DETAILED DESCRIPTION

(12) With reference to FIG. 1, an automatic packaging machine for paper bags according to a preferred embodiment of the present invention comprises: a support platform 1, a rotation table 2, a stacking device 3, a displacement device 4, a packaging device 5, and a paper delivery device 6.

(13) The support platform 1 includes multiple paper bags A delivered thereon.

(14) The rotation table 2 is connected with the support platform 1 and is configured to rotate the multiple paper bags A at two opposite angles.

(15) The stacking device 3 is connected with the rotation table 2 and is configured to stack the multiple paper bags which are rotated by the rotation table by moving downward.

(16) The displacement device 4 is mounted below the stacking device 3 and is configured to deliver the multiple paper bags A, and the displacement device 4 includes a clamper 41 and a rail 42 on which the clamper 41 is mounted and moves horizontally, wherein the clamper 41 is configured to move vertically and to clamp the multiple paper bags A securely.

(17) The packaging device 5 is connected on the displacement device 4, and the packaging device 5 includes an entering platform 51, a press plate 52, and a glue sprayer 53, wherein an inlet 511 of the entering platform 51 accommodates the press plate 52, and the glue sprayer 53 is fixed on a predetermined position of the entering platform 51.

(18) The paper feeder 6 is connected with the packaging device 5 and is configured to deliver multiple packing papers 61 onto the entering platform 51.

(19) The packaging device 5 includes a pusher 54 disposed on a side thereof and configured to push the multiple paper bags which are packaged to a designated location, as shown in FIG. 10.

(20) The support platform 1 is connected with a bag manufacturing machine 7 so as to package the multiple paper bags produced by the bag manufacturing machine 7, as shown in FIG. 11.

(21) Referring to FIGS. 1 and 2, in operation, the multiple paper bags A are delivered on the support platform 1, and a worker stands beside the support platform 1 to inspect whether the multiple paper bags have defects, such as skewed bags or damaged bags. Before the multiple paper bags are carried to the rotation table 2 (also as illustrated in FIGS. 3-4), a direction of an opening of the multiple paper bags A faces forward or rearward. After the multiple paper bags are delivered into the rotation table 2, the multiple paper bags are rotated to 90 degrees so that the opening of the multiple paper bags A are in a left or right side, then the multiple paper bags A are moved to the stacking device 3 (as shown in FIG. 5) and are displaced downward so that a highest position of the multiple paper bags A is parallel to the automatic packaging machine, and the rotation table 2 holds the multiple paper bags continuously, wherein some paper bags which are rotated last time in a direction are opposite to the other paper bags which are rotated this time in another direction. For example, same paper bags are rotated last time in a left direction, and the other paper bags are rotated this time in a right direction. Thereafter, the multiple paper bags A are delivered to the stacking device 3 and are stacked to a predetermined height so that the displacement device 4 picks and displaces the multiple paper bags under an inlet of the packaging device 5 (as illustrated in FIGS. 6-9). In the meantime, the multiple packing paper 61 are fed and transported to a feeding platform 51 of the packaging device 5 by the paper feeder 6 so that the displacement device 4 displaces the multiple paper bags A to the feeding platform 51, and the press plate 52 of the packaging device 5 presses the multiple paper bags A and the multiple packaging papers 61 to the displacement device 4. Thereafter, the multiple paper bags A are moved upward with the multiple packaging papers 61 so that the glue sprayer 53 sprays glues to the multiple packing bags 61 on the feeding platform 51, thus adhering the multiple paper bags A with the multiple packing papers 61 to produce multiple finished paper bags automatically.

(22) Thereafter, the packaging device 5 packages the multiple finished paper bags A and pushes the multiple finished paper bags A to a product collection platform 8 so that the worker collects and stores the multiple finished paper bags A.

(23) Accordingly, the automatic packaging machine is capable of packaging the multiple paper bags automatically to reduce package cost and labor consumption.

(24) While the first embodiments of the invention have been set forth for the purpose of disclosure, modifications of the disclosed embodiments of the invention as well as other embodiments thereof may occur to those skilled in the art. The scope of the claims should not be limited by the first embodiments set forth in the examples, but should be given the broadest interpretation consistent with the description as a whole.
