Technical Field
[0001] This utility model belongs to the field of packaging film printing technology, and in particular relates to a paper packaging film printing device with a feeding auxiliary structure. Background Technology
[0002] Packaging film printing is used to produce packaging films with specific patterns. Generally, patterns, text, or other information are printed on various types of packaging films. By printing text, symbols, and charts, information is fixed on paper to achieve long-term preservation and wide dissemination. Printing technology can quickly reproduce a large amount of content, ensuring the consistency of information content and avoiding errors.
[0003] After the paper packaging film is printed, a new film roll needs to be replaced. The film roll needs to be fitted onto the surface of the roll and placed on the unwinding bracket. During the film roll replacement process, some equipment uses bolts to fix it. In order to improve the convenience of replacing the paper packaging film roll, a paper packaging film printing device with a feeding auxiliary structure is needed. The motor drives two sliders to move relative to each other, so that the two sliders drive the arc plate fixed to them to clamp and fix the roll, which effectively improves the convenience of replacing the paper packaging film roll and has a better fixing effect. Utility Model Content
[0004] The purpose of this utility model is to provide a paper packaging film printing device with a feeding auxiliary structure. It has the function of driving two sliders to move relative to each other by a motor, so that the two sliders drive the clamping plates fixed to them to clamp and fix the roll, which effectively improves the stability of the film roll position during paper packaging film printing and has a better fixing effect, so as to solve the above-mentioned technical problems.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A paper packaging film printing device with a feeding auxiliary structure includes a worktable, a printing machine fixedly connected to the top of the worktable, a roll unwinding bracket fixedly connected to the top of the worktable by bolts, a roll of film sleeved on the inner wall of the roll unwinding bracket, U-shaped plates fixedly connected to the left and right sides of the roll unwinding bracket, a motor fixedly connected to the left and right sides of the roll unwinding bracket by bolts, a threaded rod fixedly connected to the output shaft of the motor, an internal threaded slider threadedly connected to the surface of the threaded rod, two symmetrical rotating plates rotatably connected to the front side of the internal threaded slider, sliders rotatably connected to the surfaces of the two rotating plates, a limit rod fixedly connected to the inner wall of the U-shaped plate, a connecting rod fixedly connected to the top of the two sliders, an ear block provided on the inner wall of the connecting rod, and an arc-shaped plate fixedly connected to the surface of the ear block.
[0006] Preferably, a limiting block is welded to the top of the threaded rod.
[0007] Preferably, the slider and the limiting rod are slidably connected.
[0008] Preferably, a bolt rod is installed between the connecting rod and the lug, and a nut block is threaded onto the surface of the bolt rod.
[0009] Preferably, the inner wall of the arc-shaped plate is covered with an anti-slip pad.
[0010] The beneficial effects of this utility model are:
[0011] 1. This utility model uses a threaded rod to drive an internal threaded slider to move on its surface, which in turn drives two sliders to move relative to each other. This causes two connecting rods to drive the arc-shaped plates fixed to them to move relative to each other and clamp and fix the roll, thereby effectively improving the stability of the film roll position during paper packaging film printing and achieving a better fixing effect.
[0012] 2. This utility model limits the movement of the internal thread slider by setting a limiting block, thus preventing the internal thread slider from accidentally scratching the surface of the threaded rod during movement.
[0013] 3. This utility model allows for the separation of the connecting rod and the arc plate through the combined use of the bolt rod and the nut block, facilitating subsequent maintenance and replacement of the arc plate and improving the applicability of the structure.
[0014] 4. By adding an anti-slip pad, this utility model increases the friction on the surface of the curved plate and improves the stability of the curved plate when clamping the roll. Attached Figure Description

[0022] In the following description, embodiments of the paper packaging film printing apparatus of the present invention with a feeding auxiliary structure will be described with reference to the accompanying drawings.
[0023] Example 1:
[0024] Figure 1-4 This invention illustrates a paper packaging film printing device with a feeding auxiliary structure according to an embodiment of the present invention. The device includes: a workbench 1; a printing machine 2 fixedly connected to the top of the workbench 1; a roll unwinding bracket 3 fixedly connected to the top of the workbench 1 by bolts; a roll 4 provided on the inner wall of the roll unwinding bracket 3; a film roll 5 sleeved on the surface of the roll 4; U-shaped plates 6 fixedly connected to both the left and right sides of the roll unwinding bracket 3; and motors 7 fixedly connected to both the left and right sides of the roll unwinding bracket 3 by bolts. A threaded rod 8 is fixedly connected to the output shaft of the motor 7. A limit block 9 is welded to the top of the threaded rod 8. The limit block 9 limits the movement of the internal threaded slider 10, preventing the internal threaded slider 10 from moving freely. In the event of accidental scraping of the surface of the threaded rod 8 during movement, the surface of the threaded rod 8 is threadedly connected to an internally threaded slider 10. The front side of the internally threaded slider 10 is rotatably connected to two symmetrical rotating plates 11. The surfaces of the two rotating plates 11 are rotatably connected to sliders 12. The inner wall of the U-shaped plate 6 is fixedly connected to a limit rod 13. The top of the two sliders 12 is fixedly connected to a connecting rod 14. The inner wall of the connecting rod 14 is provided with an ear block 15. The surface of the ear block 15 is fixedly connected to an arc-shaped plate 18. The inner wall of the arc-shaped plate 18 is attached with an anti-slip pad 19. The anti-slip pad 19 increases the friction of the surface of the arc-shaped plate 18 and improves the stability of the arc-shaped plate 18 when clamping the scroll 4.
[0025] Example 2:
[0026] Figure 1-4This invention illustrates a paper packaging film printing device with a feeding auxiliary structure according to an embodiment of the present invention. The device includes: a workbench 1; a printing machine 2 fixedly connected to the top of the workbench 1; a roll unwinding bracket 3 fixedly connected to the top of the workbench 1 by bolts; a roll 4 disposed on the inner wall of the roll unwinding bracket 3; a film roll 5 sleeved on the surface of the roll 4; U-shaped plates 6 fixedly connected to the left and right sides of the roll unwinding bracket 3; and motors 7 fixedly connected to the left and right sides of the roll unwinding bracket 3 by bolts. A threaded rod 8 is fixedly connected to the output shaft of the motor 7. An internally threaded slider 10 is threadedly connected to the surface of the threaded rod 8. Two symmetrical rotating plates 11 are rotatably connected to the front side of the internally threaded slider 10. Slider 12 is rotatably connected to the surface of plate 11. Limiting rod 13 is fixedly connected to the inner wall of U-shaped plate 6. Slider 12 and limiting rod 13 are slidably connected. Connecting rod 14 is fixedly connected to the top of each slider 12. Ear block 15 is provided on the inner wall of connecting rod 14. Bolt rod 16 is installed between connecting rod 14 and ear block 15. Nut block 17 is threadedly connected to the surface of bolt rod 16. By using bolt rod 16 and nut block 17 together, connecting rod 14 and arc plate 18 can be separated to facilitate subsequent maintenance and replacement of arc plate 18, thus improving the applicability of the structure. Arc plate 18 is fixedly connected to the surface of ear block 15.
[0027] Working principle: When using this utility model, the user places the film roll 5 on the surface of the roll 4 and then places it on the inner wall of the unwinding bracket 3. At this time, the motor 7 is started, which drives the threaded rod 8 to rotate, thereby causing the internal threaded slider 10 to move on the surface of the threaded rod 8. At this time, through the cooperation of the rotating plate 11 and the limiting rod 13, the two sliders 12 move relative to each other on the surface of the limiting rod 13. This causes the two sliders 12 to drive the connecting rod 14 fixed to them to move relative to each other. Then, the two connecting rods 14 drive the two arc plates 18 to move relative to each other, thereby causing the arc plates 18 to clamp and fix the roll 4. This effectively improves the stability of the film roll position during paper packaging film printing and achieves a better fixing effect.
[0028] In summary, this paper packaging film printing device with a feeding auxiliary structure drives the internal threaded slider 10 to move on its surface via the threaded rod 8. This causes the internal threaded slider 10 to drive the two sliders 12 to move relative to each other, thereby causing the two connecting rods 14 to drive the arc plate 18 fixed to them to move relative to each other and clamp and fix the roll 4. This effectively improves the stability of the film roll position during paper packaging film printing and provides a better fixing effect.
