Description

Technical Field

[0001] This utility model relates to the field of plastic packaging bag processing technology, and in particular to a winding structure for a wear-resistant plastic packaging bag. Background Technology

[0002] Plastic packaging bags are packaging bags made of plastic as raw material, used in the production and daily life of various products. They are widely used in daily life and industrial production. However, this convenience brings long-term harm. Most commonly used plastic packaging bags are made of polyethylene film, which is non-toxic and can therefore be used to hold food. The existing roll-up structure of a wear-resistant plastic packaging bag can basically meet the needs of daily use, but there are still some shortcomings that need to be improved.

[0003] As disclosed in a Chinese patent, a plastic packaging bag winding device includes two support plates. Each support plate has a winding shaft inside. One of the winding shafts has several identical slots on its right side, and the other winding shaft has several identical support shafts fixedly installed on its left side. The outer surface of each support shaft engages with the inside of a slot. Each support plate has a base on its bottom surface. One of the bases has two grooves on its upper surface, and two sliding rods are fixedly installed on the inner wall of each groove. This plastic packaging bag winding device, by incorporating support plates, winding shafts, slots, support shafts, bases, grooves, sliding rods, and hydraulic push rods, modifies the structure of the winding shaft. The hydraulic push rods then move the support plates, separating the winding shafts and facilitating the removal of the wound packaging bag from them.

[0004] However, the above technical solution still has the following shortcomings in actual use. When the hydraulic push rod moves the support plate and separates the winding shaft, the packaging bag on the winding shaft is easy to fall directly off the winding shaft. The fallen packaging bag is easy to enter the inside of the lower roller, causing the roller to jam and the surface of the packaging bag to be damaged. To solve the above problems, we propose a winding structure for wear-resistant plastic packaging bags. Utility Model Content

[0005] The purpose of this invention is to provide a winding structure for wear-resistant plastic packaging bags to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a winding structure for a wear-resistant plastic packaging bag, comprising a first upright, a second upright, and a roller. The roller is located at the bottom of the first and second uprights. A first drive motor is located at the top of the second upright. The output end of the first drive motor is connected to a winding shaft. A support frame is located at the top of the first upright. A second winding shaft is rotatably connected to the support frame. Two sets of sliding grooves are provided at the top of the first upright. Sliding blocks are slidably connected within each of the two sets of sliding grooves. Movable seats are installed at the top of each of the two sets of sliding blocks. A linear actuator is installed at the top of the movable seat. The output end of the linear actuator is connected to the outer wall of the movable seat. A rotating drum is installed on the movable seat. A rotating shaft is rotatably connected inside the rotating drum. The support frame is fixed to the top of the rotating shaft. A driven gear is fixed to the outside of the rotating drum. A second drive motor is installed on the lower right outer wall of the support frame. A driving gear is installed at the output end of the second drive motor. The driving gear meshes with the driven gear. An auxiliary feeding assembly is located at the upper end of the support frame.

[0007] As an improved technical solution, the auxiliary material feeding assembly includes a sleeve, a lead screw, a third drive motor, a threaded cylinder, a guide groove, a guide rod, a cross link, and a first lever. The sleeve is fixed to the upper side of the end of the support frame away from the first upright. The lead screw is rotatably connected inside the sleeve. The third drive motor is installed at the end of the sleeve away from the support frame. The output end of the third drive motor is connected to the end of the lead screw. The threaded cylinder is threaded to the outside of the lead screw. A guide groove is opened at the upper end of the sleeve. The outer wall of the top of the threaded cylinder is connected to the cross link through the guide rod. The guide rod can pass through the inside of the guide groove. The first lever and the second lever are fixed to both sides of the bottom end of the cross link, respectively.

[0008] As an improved technical solution, a storage box is installed on the top of the first stand, and a groove corresponding to the linear actuator is opened at the bottom of the storage box.

[0009] As an improved technical solution, a slot is provided at the end of the take-up shaft one facing the take-up shaft two, and a card plate corresponding to the slot on the take-up shaft one is installed at the end of the take-up shaft two facing the take-up shaft one.

[0010] As an improved technical solution, the input terminals of the linear driver, the second drive motor, and the third drive motor are all electrically connected to an external controller via wires.

[0011] As an improved technical solution, the surfaces of the two sets of first levers at the bottom of the cross link are all coated with a rubber coating.

[0012] As an improved technical solution, the outer wall of the guide rod is fully fitted with the inner wall of the guide groove on the sleeve, and the guide rod and the guide groove form a sliding connection.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are:

[0014] I. This utility model features a laterally movable seat installed at the bottom of the support frame. A linear drive can be activated, causing the movable seat and two sets of sliders to move laterally. This allows the support frame to move the second take-up shaft and the packaging bag on its surface away from the first take-up shaft. Then, a second drive motor can be activated, causing the drive gear to rotate the shaft at the bottom of the support frame along the inside of the drum. This allows the support frame to rotate the second take-up shaft 180 degrees, causing the packaging bag on the surface of the second take-up shaft to move away from the top of the drum. This effectively prevents the packaging bag from falling onto the drum, allowing the first and second take-up shafts to separate stably and effectively guiding the packaging bag on the surface of the second take-up shaft away from the top of the drum, reducing the risk of the packaging bag falling.

[0015] II. This utility model, by installing a laterally movable horizontal connecting rod on the support frame, allows the first and second levers on the horizontal connecting rod to assist in feeding packaging bags on take-up shaft one and take-up shaft two. The first lever can first move the packaging bag on the surface of take-up shaft one to the right, allowing the packaging bag to slowly move to the surface of take-up shaft two. When the support frame drives take-up shaft two and the packaging bag on it to rotate 180 degrees, the horizontal connecting rod can then drive the second lever to laterally feed the packaging bag on the surface of take-up shaft two, allowing the packaging bag on take-up shaft two to leave the surface of take-up shaft two, thereby facilitating the quick unloading of packaging bags from the surface of take-up shaft two and improving the convenience of using the device.

[0027] Figures 1 to 5As shown, this embodiment provides a winding structure for a wear-resistant plastic packaging bag, including a first upright 1, a second upright 2, and a roller 3. The roller 3 is located at the bottom of the first upright 1 and the second upright 2. A first drive motor 4 is located at the top of the second upright 2, and the output end of the first drive motor 4 is connected to a winding shaft 5. A support frame 6 is located at the top of the first upright 1, and a second winding shaft 7 is rotatably connected to the support frame 6. Two sets of sliding grooves 8 are opened at the top of the first upright 1, and sliders 9 are slidably connected within each set of sliding grooves 8. Movable parts are installed at the top of each set of sliders 9. A linear actuator 11 is mounted on the top of the movable seat 10. The output end of the linear actuator 11 is connected to the outer wall of the movable seat 10. A rotating drum 12 is mounted on the movable seat 10. A rotating shaft 13 is rotatably connected inside the rotating drum 12. A support frame 6 is fixed to the top of the rotating shaft 13. A driven gear 14 is fixed to the outside of the rotating drum 12. A second drive motor 15 is mounted on the lower right outer wall of the support frame 6. A drive gear 16 is mounted on the output end of the second drive motor 15. The drive gear 16 meshes with the driven gear 14. An auxiliary feeding assembly is provided on the upper end of the support frame 6.

[0028] By installing a laterally movable seat 10 at the bottom of the support frame 6, after the winding shaft 5 and winding shaft 7 have finished winding the packaging bag, the linear driver 11 is then activated. The linear driver 11 drives the movable seat 10 and the two sets of sliders 9 to move laterally, allowing the support frame 6 to move the winding shaft 7 and the packaging bag on its surface away from the winding shaft 5. Then, the second drive motor 15 is activated, allowing the drive gear 16 to drive the rotating shaft 13 at the bottom of the support frame 6 to rotate along the inside of the rotating drum 12, allowing the support frame 6 to rotate the winding shaft 7 180 degrees, so that the packaging bag on the surface of the winding shaft 7 is away from the top of the drum 3. This effectively prevents the packaging bag from falling onto the drum 3, allowing the winding shaft 5 and winding shaft 7 to separate stably, and effectively guiding the packaging bag on the surface of the winding shaft 7 away from the top of the drum 3, reducing the risk of the packaging bag falling.

[0029] In other embodiments, the auxiliary material feeding assembly includes a sleeve 17, a lead screw 18, a third drive motor 19, a threaded cylinder 20, a guide groove 21, a guide rod 22, a cross link 23, and a first lever 24. The sleeve 17 is fixed on the upper side of the end of the support frame 6 away from the first stand 1. The lead screw 18 is rotatably connected inside the sleeve 17. The third drive motor 19 is installed on the end of the sleeve 17 away from the support frame 6. The output end of the third drive motor 19 is connected to the end of the lead screw 18. The threaded cylinder 20 is threadedly connected to the outside of the lead screw 18. The upper end of the sleeve 17 has a guide groove 21. The outer wall of the top end of the threaded cylinder 20 is connected to the cross link 23 through the guide rod 22. The guide rod 22 can pass through the inside of the guide groove 21. The first lever 24 and the second lever 25 are fixed on both sides of the bottom end of the cross link 23, respectively.

[0030] When it is necessary to separate take-up shaft 5 and take-up shaft 7, start the third drive motor 19. The threaded cylinder 20 outside the lead screw 18 will drive the cross link 23 to move to the right under the guidance of the thread and the guide rod 22. The first lever 24 on the cross link 23 will first push the packaging bag on the surface of take-up shaft 5 to the right, so that the packaging bag will slowly move to the surface of take-up shaft 7. When the support frame 6 drives take-up shaft 7 and the packaging bag on it to rotate 180 degrees, the third drive motor 19 will drive the lead screw 18 to rotate in the opposite direction. This will allow the cross link 23 to drive the second lever 25 to push the packaging bag on the surface of take-up shaft 7 to the right again, so that the packaging bag on take-up shaft 7 will leave the surface of take-up shaft 7. This makes it easier to quickly unload the packaging bag on the surface of take-up shaft 7 and improves the convenience of using the device.

[0031] In other embodiments, a storage box 26 is installed at the top of the first stand 1, and a groove corresponding to the linear actuator 11 is opened at the bottom of the storage box 26.

[0032] This design allows the storage box 26 to be placed outside the linear drive 11 and enables the storage box 26 to receive packaging bags that fall off the reel 2 7.

[0033] In other embodiments, a slot is provided at one end of the take-up shaft 5 facing the take-up shaft 7, and a card plate corresponding to the slot on the take-up shaft 5 is installed at one end of the take-up shaft 7 facing the take-up shaft 5.

[0034] This design allows the take-up shaft 2 7 to drive the plate on it to insert into the slot on the take-up shaft 1 5, so that when the first drive motor 4 drives the take-up shaft 1 5 to rotate, the take-up shaft 2 7 can rotate synchronously with the take-up shaft 1 5.

[0035] In other embodiments, the input terminals of the linear driver 11, the second drive motor 15, and the third drive motor 19 are all electrically connected to an external controller via wires.

[0036] This design allows an external controller to control the start and stop of the linear drive 11, the second drive motor 15, and the third drive motor 19 in real time, ensuring that the linear drive 11, the second drive motor 15, and the third drive motor 19 can operate accurately.

[0037] In other embodiments, the surfaces of the two sets of first levers 24 at the bottom of the cross link 23 are all coated with a rubber coating.

[0038] With this design, when the two sets of first levers 24 move to the packaging bag side of the surface of the first winding shaft 5 and the second winding shaft 7, it can effectively prevent the two sets of first levers 24 from damaging the surface of the packaging bag.

[0039] In other embodiments, the outer wall of the guide rod 22 is fully fitted with the inner wall of the guide groove 21 on the sleeve 17, and the guide rod 22 and the guide groove 21 form a sliding connection;

[0040] With this design, when the guide rod 22 can slide smoothly laterally along the inside of the guide groove 21, it can be ensured that the guide rod 22 can drive the cross link 23 and the two sets of first levers 24 on it to move smoothly laterally.

[0041] The electrical components mentioned in this article are all electrically connected to an external main controller and industrial power supply, and the main controller can be a conventional known device such as a computer that provides control.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
