DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0019] Please refer to Figures 1-3, An automatic winding machine for plastic bags, including a winding roller 1. An installation cavity is provided inside the winding roller 1. A set of sliding grooves are provided on both the upper and lower sides of the winding roller 1, and the sliding grooves communicate with the installation cavity. Two sets of installation holes are evenly provided on the front side of the winding roller 1. A fixing component is placed in the installation cavity. The fixing component includes a sliding plate 112. A set of connecting plates 111 are fixedly provided on the opposite sides of the two sliding plates 112. A set of anti-slip pads 11 are fixedly provided on the opposite sides of the two connecting plates 111. Two sets of threaded holes are evenly provided on the outer side wall of the sliding plate 112. A bidirectional lead screw 161 is screwed into the threaded holes of the two sliding plates 112. A worm gear 162 is fixedly provided on the outer ring of the bidirectional lead screw 161. A worm 16 is engaged with the outer side wall of the worm gear 162. An internal hexagonal groove 17 is provided on the front side of the worm 16. Use two hexagonal wrenches to insert into the two internal hexagonal grooves 17 respectively and rotate them simultaneously to drive the worm 16 to rotate. The worm 16 drives the bidirectional lead screw 161 to rotate through the worm gear 162. The two sliding plates 112 are driven by the bidirectional lead screw 161 to move outward, and then the anti-slip pads 11 are driven by the connecting plates 111 to move synchronously. A first scale bar 12 is printed on the left side of the outer side wall of the anti-slip pad 11, and a second scale bar 121 is printed on the right side of the outer side wall of the anti-slip pad 11. The first scale bar 12 and the second scale bar 121 are mirror-designed. Through the first scale bar 12 and the second scale bar 121, it is convenient for users to place the winding paper tube 13 in the middle on the outer side of the winding roller 1, so as to ensure the accuracy of the winding of the plastic bag 14 on the winding paper tube 13 in the later stage. The bidirectional lead screw 161 and the worm 16 are both rotatably arranged in the installation cavity of the winding roller 1. The front side of the worm 16 is located in the installation hole of the winding roller 1. The anti-slip pad 11 is slidably arranged in the sliding groove of the winding roller 1. A set of clamping grooves 15 are provided on both the left and right sides of the outer side wall of the winding roller 1. The winding roller 1 can be placed on the roller bracket of the automatic winding machine through the clamping grooves 15. A winding paper tube 13 is sleeved on the outer ring of the winding roller 1. A plastic bag 14 is wound on the outer side wall of the winding paper tube 13. The opposite sides of the two anti-slip pads 11 are both attached to the inner side wall of the winding paper tube 13. The inner side wall of the winding paper tube 13 can be squeezed and fixed by the outward-moving anti-slip pads 11. Utilizing the self-locking property of the worm 16 and the worm gear 162, the stability of the position of the anti-slip pad 11 after adjustment can be ensured, and further the stability of the winding paper tube 13 when being wound by the plastic bag 14 can be ensured. By changing the outward movement distance of the anti-slip pad 11, the winding roller 1 can quickly fix winding paper tubes 13 of different sizes, thereby improving the adaptability of the automatic winding machine.
[0020] Working principle: The winding roller 1 can be placed on the roller bracket of the automatic wrapping machine through the card slot 15. The first scale bar 12 and the second scale bar 121 facilitate the user to place the wrapping paper tube 13 in the center on the outside of the winding roller 1, so as to ensure the accuracy of the wrapping of the plastic bag 14 around the wrapping paper tube 13 in the later stage. Two sets of hexagonal wrenches are inserted into the two sets of internal hexagonal slots 17 respectively and rotated simultaneously to drive the worm 16 to rotate. The worm 16 drives the bidirectional lead screw 161 to rotate through the worm gear 162. The bidirectional lead screw 161 drives the two driving slides 112 to move outwards, and then drives the anti-slip pad 11 to move synchronously through the connecting plate 111. The inner side wall of the wrapping paper tube 13 can be squeezed and fixed by the outward moving anti-slip pad 11. Utilizing the self-locking property of the worm 16 and the worm gear 162, the stability of the position of the anti-slip pad 11 after adjustment can be ensured, and further the stability of the wrapping paper tube 13 when being wrapped by the plastic bag 14 can be ensured. By changing the outward movement distance of the anti-slip pad 11, the winding roller 1 can quickly fix wrapping paper tubes 13 of different sizes, thereby improving the adaptability of the automatic wrapping machine.
