Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Specific examples are given below.

[0025] See also Figure 1 - Figure 4 The utility model provides a food packaging bag production and trimming device, including a body 1, the four corners of the body 1 are fixedly connected with a positioning column 2, the inner wall of each positioning column 2 is rotatably connected to two bearings 3, a guide roller 4 is rotatably connected between every two bearings 3, and a packaging bag material belt 7 is rotatably connected between multiple guide rollers 4. A limiting groove 8 is provided in the middle of the body 1, and movable blocks 9 are sleeved at both ends of the limiting groove 8. A limiting block 12 is fixedly connected to the middle of the limiting groove 8. A second motor 11 is fixedly connected to one side of the body 1, and one end of the output shaft of the second motor 11 is fixedly connected to a bidirectional threaded rod 10. The bidirectional threaded rod Both ends of 10 are rotatably connected to the inner wall of the body 1, and the outer walls of the two-way threaded rod 10 are threadedly connected to the inner wall of the movable block 9. The two movable blocks 9 are slidably connected to the inside of the limit groove 8 through the two-way threaded rod 10. An open groove 16 is provided on the inner wall of one end of each movable block 9. A third motor 17 is sleeved inside each open groove 16. A cutter 18 is fixedly connected to one end of the output shaft of each third motor 17. A top plate 19 is fixedly connected to one side of each top plate 19. One side of each top plate 19 is fitly connected to one side of the packaging bag material belt 7, and each cutter 18 is rotatably connected to the top of the top plate 19.

[0026] During operation, the packaging bag material strip 7 is passed through multiple guide rollers 4 and arranged horizontally on the top of the machine body 1. The bearings 3 reduce friction with the positioning columns 2, improving the rotation efficiency of the guide rollers 4. The rotation of the multiple guide rollers 4 guides and conveys the packaging bag material strip 7. When the edge of the packaging bag material strip 7 needs to be cut, the second motor 11 is activated. The output shaft of the second motor 11 drives the bidirectional threaded rod 10 to rotate, which in turn drives the two movable blocks 9 to slide within the limit slots 8. The limit blocks 12 prevent collision between the two movable blocks 9. When moved to the appropriate position, the cutter 18 contacts both ends of the packaging bag material strip 7. The two top plates 19 are aligned with the bottom side of the packaging bag material strip 7 to prevent wrinkles during conveyance. The third motor 17 is then activated. The output shaft of the third motor 17 drives the cutter 18 to rotate. The cutter 18 cooperates with the top plate 19 to complete the trimming of the packaging bag material strip 7. By adopting the above method, when the size of the packaging bag material strip 7 changes, by starting the second motor 11 to adjust the position between the two movable blocks 9, the trimming requirements of packaging bag material strips 7 of different sizes can be met, and it is convenient for the staff to quickly adjust the equipment, which can improve the practicality and work efficiency of the trimming device.

[0027] Further, such as Figure 2 As shown, two first motors 6 are fixedly connected to one side of the body 1, one end of the output shaft of each first motor 6 is fixedly connected to one end of the guide roller 4, and the outer wall of one end of each guide roller 4 is fixedly connected to a transmission gear 5, and every two transmission gears 5 are meshed and connected.

[0028] During operation, by starting the first motor 6, the output shaft of the first motor 6 is used to drive the guide roller 4 to rotate, which can drive the transmission gear 5 to rotate. The transmission gear 5 is then engaged with another transmission gear 5 to make the other guide roller 4 rotate synchronously, thereby ensuring the rotation efficiency of the guide roller 4, ensuring the conveying efficiency of the packaging bag material belt 7, and improving the practicality of the device.

[0029] Further, such as Figure 3 As shown, a plurality of positioning blocks 15 are provided on both sides of the limiting groove 8. One end of each positioning block 15 is fixedly connected to one side of the body 1, and a slide bar 14 is fixedly connected between every two positioning blocks 15. A rectangular block 13 is fixedly connected to both sides of each movable block 9. The inner wall of each rectangular block 13 is slidably connected to the outer wall of the slide bar 14, and each movable block 9 slides between the slide bars 14 via two rectangular blocks 13.

[0030] During operation, when the second motor 11 drives the movable block 9 to move, the rectangular blocks 13 on both sides can be driven to slide outside the slide bar 14. The positioning blocks 15 can ensure the stability of the slide bar 14, so that the slide bar 14 is fixed on both sides of the limit groove 8. The connection between the rectangular blocks 13 and the slide bar 14 can prevent the movable block 9 from being misaligned during movement, thereby improving the stability and service life of the structure.

[0031] Further, such as Figure 4 As shown, push plates 20 are fixedly connected to both sides of each third motor 17. Each push plate 20 is slidably connected to the inner wall of the opening slot 16 via the third motor 17. Two electric push rods 21 are fixedly connected to one side of each push plate 20. One end of each electric push rod 21 is fixedly connected to the inner wall of the opening slot 16. Each third motor 17 slides inside the opening slot 16 via multiple electric push rods 21, and a return spring 22 is sleeved on the outside of each electric push rod 21.

[0032] During operation, the extension or contraction of the electric push rod 21 drives the push plate 20 to slide within the opening slot 16. The fixed connection between the push plate 20 and the third motor 17 allows the third motor 17 to slide synchronously within the opening slot 16, facilitating adjustment of the trim width of the packaging bag web 7. Furthermore, the sliding movement between the outer wall of the push plate 20 and the inner wall of the opening slot 16 prevents the third motor 17 from falling off. The elastic force of the return spring 22 enhances the structure's anti-seismic effect, thereby increasing the service life of the device.

[0033] Working Principle: The packaging bag material strip 7 is passed through multiple guide rollers 4 and arranged horizontally on top of the machine body 1. The first motor 6 is activated, and its output shaft drives the guide roller 4 to rotate. The meshing of two transmission gears 5 then synchronizes the rotation of the other guide roller 4. Bearings 3 reduce friction with the positioning column 2. The rotation of the multiple guide rollers 4 guides and conveys the packaging bag material strip 7. When the edges of the packaging bag material strip 7 need to be cut, the second motor 11 is activated, and its output shaft drives the bidirectional threaded rod 10 to rotate. This causes the two movable blocks 9 to slide within the limiting slots 8, which in turn drives the rectangular block 13 to slide outside the slide rod 14, preventing the movable blocks 9 from misaligning during movement. Once the movable blocks 9 are moved to the appropriate position, the extension or contraction of the electric push rod 21 drives the push plate 20 to slide within the opening slot 16. The fixed connection between the push plate 20 and the third motor 17 causes the third motor 17 to slide synchronously within the opening slot 16, allowing the trimming width of the packaging bag material strip 7 to be adjusted. The cutter 18 is brought into contact with both ends of the packaging bag material strip 7, and the top plate 19 is brought into contact with one side of the bottom of the packaging bag material strip 7. The third motor 17 is then started, and the output shaft of the third motor 17 drives the cutter 18 to rotate. The cutter 18 and the top plate 19 cooperate to trim the edge of the packaging bag material strip 7.
