DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0038] In the present embodiment, a double-unit imprinting element is used as an example for description and is only used to allow a person in this technical field to understand the present invention more comprehensively, without limiting the present invention in any way of restriction.

[0039] Referring to FIG. 1 and FIG. 2, a position fine tuning device used for a unit-type die cutting & hot stamping machine comprises a paper delivering element 16, an imprinting element and a paper receiving element 20. These parts are carried and surrounded commonly by a casing 18.

[0040] Paper 17 for imprinting is delivered by a gripper 6 installed on chains 8. Two ends of the said gripper 6 are fixed on two transmission chains 8 which are closed and parallel to each other, a grip body 11 of the gripper 6 and the chain 8 are fixed and connected through a connecting block 10 (as shown in FIGS. 1 to 4).

[0041] The said imprinting element includes a fixed platform and a movable platform. The fixed platform and the movable platform of each imprinting element can be installed with a die cutting or indenting tool to implement paper cutting and indenting (as shown in FIG. 1 and FIG. 2).

[0042] The imprinting element in the said unit-type die cutting & hot stamping machine for accomplishing the hot stamping procedure includes an aluminum foil control element, constituting a hot foil stamping control element. The said hot foil stamping control element can be added to the aluminum foil control element transversally (as shown in FIG. 1 and FIG. 2).

[0043] The fixed platform of the said imprinting element is installed with a heating system and a hot foil stamping tool to implement the hot stamping function (as shown in FIG. 1 and FIG. 2).

[0044] The said chain 8 is connected with tensioners 7 (as shown in FIGS. 2 to 4).

[0045] With the imprinting element of the unit-type die cutting & hot stamping machine including a first unit imprinting element 1 and a second unit imprinting element 2 as an example, the said imprinting element is provided with a position fine tuning device. The said imprinting element includes a first unit imprinting element, and a second unit imprinting element. The said position fine tuning device includes a front positioning element 3 disposed on an input end of the first unit imprinting element 1, a first unit rear positioning element 4 disposed on an output end of the first unit imprinting element 1, and a second unit rear positioning element 5 disposed on an output end of the second unit imprinting element 2. The front positioning element 3 and the first unit rear positioning element 4 accomplish the front positioning to the first unit imprinting element 1 together, the first unit rear positioning element 4 and the second unit rear positioning element 5 accomplish the rear positioning to the second unit imprinting element 2 together, and the three said positioning elements are disposed parallel along the direction of deliver of the chain (as shown in FIG. 2).

[0046] In the fine tuning process of the imprinting elements, one of the three positioning elements (the front positioning element 3, the first unit rear positioning element 4, and the second unit rear positioning element 5) is used as a reference, and the distance between the other two positioning elements and the reference positioning element is adjusted.

[0047] Using the first unit rear positioning element 4 as an example, the structure configurations for the three positioning elements are shown in FIGS. 2 to 10.

[0048] The front positioning element 3 is constituted by a positioning assembly installed symmetrically at each end of the imprinting element. The said positioning assembly includes a positioning rod 12 which can rotate against an installation shaft, as well as a gripper body 11 of the gripper 6. The said gripper body 11 is provided with a reference matching surface I A, and the said positioning rod 12 is provided with a positioning block 9. The said positioning block 9 is provided with a reference surface, and the reference surface of the positioning block 9 matches and positions with the reference matching surface I A of the gripper body 11.

[0049] The first unit rear positioning element 4 is constituted by a positioning assembly installed symmetrically at each end of the imprinting element. The said positioning assembly includes a positioning rod 12 which can rotate against an installation shaft, as well as a gripper body 11 of the gripper 6. The said gripper body 11 is provided with a reference matching surface II B, and the said positioning rod 12 is provided with a positioning block 9. The said positioning block 9 is provided with a reference surface, and the reference surface of the positioning block 9 matches and positions with the reference matching surface II B of the gripper body 11.

[0050] The second unit rear positioning element 5 is constituted by a positioning assembly installed symmetrically at each end of the imprinting element. The said positioning assembly includes a positioning rod 12 which can rotate against an installation shaft, as well as a gripper body 11 of the gripper 6. The said gripper body 11 is provided with a reference matching surface III C, and the said positioning rod 12 is provided with a positioning block 9. The said positioning block 9 is provided with a reference surface, and the reference surface of the positioning block 9 matches and positions with the reference matching surface III C of the gripper body 11.

[0051] The surface on which the reference matching surface II B of the first unit rear positioning element 4 matches with the positioning block 9 at that location is the reference surface.

[0052] A first embodiment of adjusting the reference matching surface is shown in FIGS. 5 to 7. Upon carrying out the position fine tuning work, the distance between the reference surface and the reference matching surface II B of the reference positioning element (i.e., the first unit rear positioning element 4) is constant. By changing the gasket 13 on the reference matching surface I A, the location of the reference matching surface I A is adjusted to accomplish front positioning. By changing the gasket on the reference matching surface III C, the location of the reference matching surface III C is adjusted to accomplish rear positioning.

[0053] A second embodiment of adjusting the reference matching surface is shown in FIGS. 8 to 10. The gripper body 11 is provided with through-holes and each of the said through-holes is installed with an adjusting pin 15. The said adjusting pin 15 is locked tightly by a tightening nut 14. Upon carrying out the position fine tuning work, tightening nut 14 is adjusted to adjust the location of the reference matching surface of the adjusting pin 15, which assures that paper held by the gripper will be aligned with the reference surface to locate at the working position, thereby accomplishing the positioning work.

[0054] As shown in FIG. 2, for an example, using the first unit rear positioning element 4 as the reference positioning, the reference matching surface II B of the gasket matches and contacts with the reference surface of the positioning block at that location, forming a reference positioning surface.

[0055] Upon carrying out the position fine tuning work, the front positioning element 3 and the second unit rear positioning element 5 are adjusted respectively, in accordance with the reference positioning surface. Referring to FIG. 2 and FIG. 8, by adjusting the tightening nut 14, the reference matching surface I A of the adjusting pin 15 is made to move toward paper, thereby accomplishing the front positioning work. As shown in FIG. 9, by adjusting the tightening nut 14, the reference matching surface III C of the adjusting pin 15 is made to move away from paper, thereby accomplishing the rear positioning work. By assuring the distance between two positioning elements to be constant, paper of each positioning element can be guaranteed to reach the established working position.

[0056] The present invention also discloses a working method of the position fine tuning device used for the unit-type die cutting & hot stamping machine. The working method is characterized in following steps: [0057] (1) Selecting a positioning element as a positioning reference, meaning that the tightly contact of the reference surface of the positioning block 9 on the positioning rod with the reference matching surface of the gripper 6 of that positioning element is used as the positioning reference; [0058] (2) Adjusting other positioning elements to accomplish positioning, meaning that the distance between the positioning block 9 on the positioning rod 12 and the corresponding reference matching surface on the gripper 6 in each positioning element is adjusted, assuring that the distance between two neighboring grippers 6 is constant to accomplish positioning.

[0059] For fine tuning the distance between the said reference matching surface and the positioning block 9, by changing the gasket in a different thickness, the location of the reference matching surface on the gasket is adjusted, so that paper can be adjusted to be located at the working position; or, the adjusting pin can be adjusted toward right or left to adjust the location of the reference matching surface on the adjusting pin, thereby adjusting paper to be located at the working position. After being transmitted from the delivering element 16 to a conveyor, paper is positioned by a positioning front guide 21 on the conveyor. A front edge of the paper after being positioned is held by the gripper 6, assuring that each working position of paper relative to the gripper 6 is kept constant. The paper that is held tightly by the gripper 6 is transmitted to a subsequent working table for the following hot stamping.

[0060] Each gripper sheet of the gripper body 11 of the said gripper 6 holds and moves paper to a working position for processing. The positioning rod 12 rotates counterclockwise, and the gripper body 11 and the connecting block 10 ascend. When the positioning rod 12 rotates to an end to contact with the reference matching surface of the connecting block 10, the initial positioning to the gripper 6 is accomplished. The reference positioning is accomplished when the reference surface contacts and matches with the reference matching surface II B of first unit rear positioning element 4; whereas, the front positioning to the first unit imprinting element 1 is accomplished by adjusting the distance between the positioning block and the reference matching surface I A of the front positioning element 3 to compensate for the deformation error of the chain 8 caused by extension and assure the distance between the front gripper 6 and the rear gripper 6 of the first unit imprinting element 1 to be constant. At the same time, the rear positioning to the second unit imprinting element 2 is accomplished by adjusting the distance between the positioning block and the reference matching surface III C of the second unit rear positioning element 5 to assure that the distance between the front gripper 6 and the rear gripper 6 of the second unit imprinting element 2 is constant. Therefore, the precision positioning to two imprinting elements is accomplished simultaneously, and at this time, two paper imprinting procedures start. After accomplishing the paper processing, the positioning rod 12 rotates clockwise, and the gripper body 11 and the connecting block 10 descend. At this time, the reference matching surface of the positioning block of the chain 8 escapes from a positioning roller. When the positioning rod 12 descends to the lowest point, the positioning rod 12 will escape completely from the reference matching surface, and the gripper 6 will hold and move paper to a next working position.

[0061] It is of course to be understood that the embodiments described herein is merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.
