Description

Technical Field

[0001] This utility model relates to the field of plastic woven bag processing technology, specifically to a locking device for processing plastic woven bags. Background Technology

[0002] Plastic woven bags, a widely used packaging product, are bag-shaped containers made primarily from plastic raw materials such as polypropylene (PP) or polyethylene (PE) through extrusion, stretching into flat filaments, and then weaving. They play an important role in daily life and industrial production due to their lightweight, durability, waterproofing, and cost-effectiveness.

[0003] However, existing edge-locking devices for plastic woven bag processing have some prominent problems in practical use. One of the most common issues is that the edge-locking operation of plastic woven bags mostly relies on manual pulling. Because the distance of manual pulling is relatively close to the edge-locking machine head, operators are easily prone to accidental contact with the high-speed rotating machine head due to negligence or improper operation, potentially causing abrasions, cuts, or even more serious injuries, threatening the operator's health. Therefore, we provide an edge-locking device for plastic woven bag processing. Utility Model Content

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figures 1-4As shown, in this embodiment, a sealing device for processing plastic woven bags includes: a flattening mechanism 1, which includes a processing table 11. A bracket 12 is fixedly connected to one side of the top of the processing table 11. A first cylinder 13 is provided on one side of the top of the bracket 12. A first piston rod 14 is provided at the bottom of the first cylinder 13. A mounting plate 15 is provided at the bottom of the first piston rod 14. The bottom of the first cylinder 13 is fixedly mounted on one side of the top of the bracket 12. The output end of the bottom of the first cylinder 13 is movably mounted to the top of the first piston rod 14. The bottom end of the first piston rod 14 is fixedly connected to the top of the mounting plate 15. Smoothing plates 16 are provided on both sides of the mounting plate 15. A pressure roller 17 is provided at the bottom of the mounting plate 15. Smoothing plates 16 are fixedly connected to both sides of the mounting plate 15. The pressure roller 17 is rotatably mounted at the bottom of the mounting plate 15. One side of the processing table 11 is fixedly mounted on... A second support plate 32 is fixedly connected. A motor 18 is installed on one side of the processing table 11. A lead screw 19 is installed in a slot opened on the top of the processing table 11. The top of the second support plate 32 is fixedly connected to the outside of the motor 18. The output end of the motor 18 is fixedly connected to one end of the lead screw 19. The other end of the lead screw 19 is rotatably connected to the inner wall of the slot opened on the top of the processing table 11, away from the motor 18. An adjusting block 110 is installed on the outside of the lead screw 19. A mounting base 111 is installed on the top of the adjusting block 110. The outside of the lead screw 19 is threadedly connected to the inner wall of the threaded groove opened on the adjusting block 110. The top of the adjusting block 110 is fixedly connected to the bottom of the mounting base 111. An adjusting bolt 112 is threadedly connected to the threaded groove opened on the top of the mounting base 111. A pressure plate 113 is rotatably connected to the bottom of the adjusting bolt 112. An adjusting mechanism 2 is installed inside the bracket 12.

[0024] In this embodiment, when the device is needed to perform edge locking on plastic woven bags, the plastic woven bags can be laid flat on the processing table 11, and one end of the woven bag can be placed in the mounting base 111. By rotating the adjusting bolt 112, the pressure plate 113 is lowered, thereby pressing and fixing the woven bag in the mounting base 111. By starting the motor 18, the lead screw 19 is driven to rotate, so the adjusting block 110 and the mounting base 111 connected to it will move horizontally, and the pressed woven bag will move on the processing table 11 as the mounting base 111 moves. The movement mentioned here refers to the activation of the drive cylinder 26, which drives the needle bar 27 to move up and down, performing edge locking on the woven bag as it moves. During the uniform movement of the woven bag on the processing table 11, the activation of the first cylinder 13 drives the first piston rod 14 to descend, thereby causing the pressure roller 17 and the smoothing plate 16 to descend synchronously. The pressure roller 17 can effectively flatten the woven bag, and the smoothing plate 16 will play an auxiliary flattening role, avoiding quality problems in edge locking caused by wrinkles in the woven bag. The range of edge locking can be precisely controlled by the scale line 33.

[0025] like Figures 1-4As shown, the adjustment mechanism 2 includes a second cylinder 21. A first support plate 31 is fixedly connected to one side of the bracket 12. The top of the first support plate 31 is fixedly installed to the outside of the second cylinder 21. A second piston rod 22 is fixedly connected to the output end of the second cylinder 21. A mounting block 23 is fixedly connected to the end of the second piston rod 22 away from the second cylinder 21. Slider blocks 24 are fixedly connected to both sides of the mounting block 23. Slide grooves 25 are opened on both sides of the inner wall of the bracket 12. The outside of the slider 24 is slidably connected to the inner wall of the slide groove 25. A drive cylinder 26 is fixedly installed on the mounting block 23. The output end of the bottom of the drive cylinder 26 is fixedly connected to the top of the needle rod 27.

[0026] In this embodiment, in order to adjust the position of the needle bar 27 for the edge-locking processing of the woven bag, the second cylinder 21 can be activated to drive the second piston rod 22 to extend and retract, thereby the mounting block 23 will move synchronously, and the slider 24 will move in the slide groove 25. The slider 24 and the slide groove 25 can ensure the stability of the mounting block 23 when it moves horizontally.

[0027] This utility model provides a locking device for processing plastic woven bags, the specific working principle of which is as follows:

[0028] When using this device to perform edge-locking on plastic woven bags, first, lay the plastic woven bag flat on the processing table 11. Then, place one end of the woven bag into the mounting base 111. By rotating the adjusting bolt 112, control the pressure plate 113 to descend, thereby pressing and fixing the woven bag in the mounting base 111. This step is crucial, as it ensures that the woven bag will not shift or shake during processing. Subsequently, start the motor 18 to drive the lead screw 19 to rotate, so that the adjusting block 110 and the mounting base 111 connected to it will move horizontally. Since one end of the woven bag has been pressed and fixed in the mounting base 111, Therefore, it moves at a constant speed on the processing table 11 as the mounting base 111 moves. This movement is continuous and stable, providing good conditions for the subsequent overlocking process. During the uniform movement of the woven bag, the drive cylinder 26 is activated to drive the needle bar 27 to move up and down back and forth, performing overlocking on the moving woven bag. When the woven bag moves at a constant speed on the processing table 11, the first cylinder 13 is activated to drive the first piston rod 14 to descend. This action will cause the pressure roller 17 and the smoothing plate 16 to descend synchronously, thereby flattening the woven bag and avoiding overlocking quality problems caused by wrinkles.

[0029] 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.
