Embodiments

[0032] With reference to FIGS. 1-4, the three-axis ribbon cutter includes a base 1, a traversing cutter set 2, a ribbon guiding mechanism 3, a first guide rail 4, a second guide rail 5, a cutting cylinder 6, a lifting cylinder 7, a traversing cylinder 8 and a ribbon 9. A mounting block is provided on the base 1 and the mounting block is connected with the first guide rail through a bolt structure or a rivet structure.

[0033] The mounting block is connected with the traversing cutter set 2, the ribbon guiding mechanism 3, the first guide rail 4, the second guide rail 5, the cutting cylinder 6, the lifting cylinder 7 and the traversing cylinder 8; cutters of the traversing cutter set 2 and the ribbon guiding mechanism 3 are provided in multiple sets, and the ribbon guiding mechanism 3 is provided with through holes matched with a number of special-shaped cutters 21. The through holes are configured to pass through a primary limit ribbon 9.

[0034] The traversing cutter set 2 includes special-shaped cutters 21 which are connected to the cutting cylinder 6 and the traversing cylinder 8, edges of the special-shaped cutters extend by a certain volume, and edges of the special-shaped cutters 21 are wider than shanks of the special-shaped cutters. After the ribbon 9 is pulled in place, the special-shaped cutters 21 will be raised to the cutting height, and the ribbon 9 will block a rising path. A similar gap is left in shanks of the special-shaped cutters 21. When the special-shaped cutter rises, it bypasses the ribbon 9 through the traversing cylinder 8, and when it reaches the height, the gap can be buckled above the ribbon 9, and when cutting is to be made, it will fall to finish the cutting.

[0035] The traversing cutter set 2 and the lower cutter 22 are both connected to the lifting cylinder 7. The traversing cutter set 2 and the lower cutter 22 are slidably connected to the mounting block through the first guide rail 4; and the second guide rail 5 is slidably connected to a bottom of the base 1. The whole device can slide and translate under an action of the second guide rail 5. The first guide rail 4 serves as a structure for lifting. Under actions of the cutting cylinder 6 and the traversing cylinder 8, the traversing cutter set 2 can traverse along its own cutter arranging direction and perform cutting actions. Lifting actions of the traversing cutter set 2 and the lower cutter 22 are carried out under control of the lifting cylinder 7, and in order to raise the cutters to a preset ribbon 9 height, the cutters are previously lower than this height to make space available for the ribbon 9 to be pulled into this device.

[0036] Edges of the special-shaped cutter 21 and the lower cutter 22 are staggered, the cutters are trapezoidal in shape, and angles of the edges are 50-90 degrees. Instead of a traditional sharp edge, a trapezoidal edge can provide a certain supporting force when the ribbon 9 is cut, while the ribbon 9 is bent when it is cut, and the trapezoidal edge can protect the ribbon 9 from being bent after cutting. Service life of the cutter is prolonged, and the cutter is not easy to become dull. The special-shaped cutters 21 and the lower cutter 22 are integrally formed. An integrally formed structure is beneficial to improve a structural strength of the special-shaped cutters 21 and the lower cutter 22.

[0037] Driving directions of the cutting cylinder 6 and the lifting cylinder 7 are perpendicular to directions of the ribbon 9 and the cutters; and a driving direction of the traversing cylinder 8 is the same as an arrangement direction of the traversing cutter set 2.

[0038] The implementation method includes following steps:

[0039] 1. A ribbon 9 pulling mechanism pulls the ribbon 9, and the cutter lifting cylinder 7 is in a low position to leave space for the ribbon 9 pulling mechanism. When the cutters at a ribbon-taking position, the cutters are at a height lower than a height of the ribbon 9, and at this time, the ribbon 9 pulling mechanism can pass tops of the cutters and pull the ribbon 9. One of advantages of this design is that space above the cutters can be opened to make room for an action of the ribbon 9 pulling mechanism, and at the same time, the open space also creates favorable conditions for multi-set handling of the ribbon 9.

[0040] 2. The lifting cylinder 7 rises to make a cutting edge of the lower cutter 22 flush with the ribbon 9, and then the transverse cylinder 8 moves to make edges of the special-shaped cutters be located directly above the ribbon 9, and then cut the ribbon 9. In an arrangement of the cutters, we combine multiple sets of cutters. An advantage of the multiple sets of cutters is that they can make cutting for multiple segments of ribbons 9 at the same time, which greatly improves cutting efficiency of the ribbon 9 and creates favorable conditions for productivity improvement of a string welder.

[0041] 3. After the cutting is finished, the special-shaped cutters rise and the transverse cylinder 8 retracts, and then the lifting cylinder 7 lowers to a low position to prepare for a next cutting.

[0042] Edges of the special-shaped cutters and only span 5-7 mm between opening and closing, and when the cutters are not in operation, they are in a low position and far away from the operator, which has a certain protective effect on safety of an operator threading the ribbon and has high safety.

[0043] The ribbon 9 pulling mechanism is an external tooling structure used to straighten the ribbon 9 and pull it to a preset cutting position of the ribbon guiding mechanism.

[0044] As shown in FIG. 4, a dotted-line part is at a high position of the lifting cylinder 7, where the special-shaped cutters 21 and the lower cutter 22 are located when the cutting is made.

[0045] The present disclosure and embodiments thereof are described above in an illustrative manner, which is not restrictive; and what is shown in the drawings is only one of the embodiments of the present disclosure, and its actual structure is not limited thereto. Therefore, structures and embodiments similar to the technical scheme designed by those of ordinary skilled in the art inspired by this disclosure without creativity, without departing from the creative purpose of the present disclosure, are all within a protection scope of the present disclosure.
