[0002] Pearl cotton, also known as polyethylene foam cotton, is a non-cross-linked closed-cell structure and a new type of environmentally friendly packaging material. It is composed of countless independent bubbles produced by physical foaming of low-density polyethylene resin. Compared with traditional foamed plastic, it has many advantages such as waterproof and moisture-proof, shockproof, sound insulation, heat preservation, good plasticity, strong toughness, recycling, environmental protection, and strong impact resistance. It also has good chemical resistance and is an ideal substitute for traditional packaging materials.

[0024] 4. A passing rod is installed between the first limiting rod and the second limiting rod, so that when the pressing conveying roller is driven to move to the limit height by rotating the adjusting rod, the first limiting rod will release the restriction on one set of protective film winding and storage rollers, and the passing rod will be aligned with another set of protective film winding and storage rollers, so that the restriction on the other set of protective film winding and storage rollers is also released. At this time, the staff can assemble the protective film winding and storage rollers through the protective film assembly holes, and perform preliminary manual traction and debugging on the pearl cotton and the protective film, thereby making assembly and debugging more convenient.

[0032] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0033] like Figure 1-Figure 6 As shown, the present invention provides a technical solution:

[0034] Example 1

[0035] A pearl cotton double-sided laminating machine, comprising a fixed base 1, both ends of the top of the fixed base 1 are equipped with mounting uprights 2, a conveyor belt assembly 4 is evenly installed at the middle position of the mounting uprights 2 near one end of the fixed base 1, and a protective film assembly hole 3 is opened at the top and bottom of one end of a group of mounting uprights 2, and an assembly fixed shaft 5 is installed at the top and bottom of another group of mounting uprights 2 near one end of the fixed base 1, and a protective film winding storage roller 6 is sleeved on the outer side of the assembly fixed shaft 5. The conveyor belt assembly 4 has the same structure as the existing conveyor belt. When in use, the protective film winding storage roller 6 is sleeved on the assembly fixed shaft 5, wherein the protective film on a group of protective film winding storage rollers 6 near the top is pulled and bonded to the top of the pearl cotton, and the protective film on a group of protective film winding storage rollers 6 near the bottom is bonded to the bottom of the pearl cotton. After assembly is completed, when the pearl cotton moves, the protective film winding storage roller 6 will move accordingly, thereby performing a double-sided laminating task, and when laminating pearl cotton of different widths, the protective film winding storage roller 6 adopts a model with the same width as the pearl cotton;

[0036] An adjusting rod 7 is passed through one end of the mounting plate 2, and a worm gear 8 is installed at one end of the adjusting rod 7 away from the fixed base 1. A special-shaped movable rod 9 is sleeved on the outer side of the adjusting rod 7, and a blocking sleeve 10 is installed at one end of the special-shaped movable rod 9. A pressing and conveying roller 11 is arranged on the inner side of the blocking sleeve 10. When in use, the pressing and conveying roller 11 presses the top of the pearl cotton. At this time, the blocking sleeve 10 always restricts one side of the pearl cotton, and the other side of the pearl cotton is restricted by a group of mounting plates 2 to prevent the pearl cotton from deviating during the movement.

[0037] The cross-sectional shape of the adjusting rod 7 is square, and the adjusting rod 7 is rotatably connected to the mounting plate 2, so that the staff can drive the pressing conveying roller 11 to adjust the upper and lower heights by rotating the adjusting rod 7, thereby pressing the pearl cotton of different thicknesses;

[0038] A threaded rod 12 is passed through one end of the worm wheel 8, and the threaded rod 12 passes through the special-shaped movable rod 9. The special-shaped movable rod 9 is slidably connected to the adjustment rod 7, and the special-shaped movable rod 9 is threadedly connected to the threaded rod 12. The central axis of the threaded rod 12 is parallel to the central axis of the adjustment rod 7, and the threaded rod 12 is rotatably connected to the worm wheel 8. During use, when the adjustment rod 7 is rotated to adjust the height of the pressing conveying roller 11, the threaded rod 12 will perform corresponding circular motion, thereby not affecting the rotation of the adjustment rod 7. The longitudinal position of the special-shaped movable rod 9 can be adjusted by rotating the threaded rod 12, so that the blocking sleeve 10 can complete the restriction of pearl cotton of different widths;

[0039] An arc-shaped mounting through hole 13 is provided at one end of the mounting vertical plate 2 close to the worm gear 8, and a driving mechanism for driving the pressing and conveying roller 11 to rotate is provided inside the arc-shaped mounting through hole 13. The driving mechanism includes a mounting plate 14, and the mounting plate 14 is arranged inside the arc-shaped mounting through hole 13. A driving motor 15 is installed at one end of the mounting plate 14 away from the fixed base 1, and the output end of the driving motor 15 is connected to the pressing and conveying roller 11, and the output shaft of the driving motor 15 passes through the mounting plate 14 and is rotatably connected to the mounting plate 14. After the assembly and debugging are completed, the conveyor belt assembly 4 can drive the pearl cotton to move forward, and the driving motor 15 drives the pressing and conveying roller 11 to rotate accordingly, thereby cooperating to complete the movement of the pearl cotton and the laminating task;

[0040] The cross-sectional shape of the mounting plate 14 is an arc, and the mounting plate 14 and the arc-shaped mounting through hole 13 form a relative sliding structure, the curvature of the mounting plate 14 is the same as the curvature of the arc-shaped mounting through hole 13, and the mounting plate 14 can be mounted on the inner side wall of the arc-shaped mounting through hole 13 through a slide groove slider, and the arc center of the arc-shaped mounting through hole 13 is located on the central axis of the adjustment rod 7, so that when the height of the pressing and conveying roller 11 is adjusted by rotating the adjustment rod 7, the mounting plate 14 can slide correspondingly inside the arc-shaped mounting through hole 13, and will not affect the adjustment of the position of the pressing and conveying roller 11;

[0041] An operating mechanism for driving the adjustment rod 7 to rotate is provided on the mounting plate 2, and the operating mechanism includes a U-shaped plate 19. The U-shaped plate 19 is installed at one end of the mounting plate 2 close to the worm gear 8. An operating mounting shaft 20 passes through one side of the U-shaped plate 19, and a worm 21 is installed on the outer side of the operating mounting shaft 20. The central axis of the worm 21 coincides with the central axis of the operating mounting shaft 20, and the worm 21 is meshingly connected with the worm wheel 8, so that the staff can drive the adjustment rod 7 to complete the corresponding rotation by rotating the operating mounting shaft 20, thereby adjusting the height of the pressing and conveying roller 11. At the same time, the worm wheel 8 cannot drive the worm 21 to rotate, so the worm 21 can form a limiting effect on the adjustment rod 7, thereby ensuring the stability of the height of the adjustment rod 7 and the pressing and conveying roller 11 during use.

[0042] Example 2

[0043] Based on the above-mentioned embodiment 1, a first limiting rod 16 is installed at one end of the special-shaped movable rod 9 away from the blocking sleeve 10, and a through rod 17 is installed at the bottom end of the first limiting rod 16, and a second limiting rod 18 is installed at one end of the through rod 17 away from the first limiting rod 16. During use, the first limiting rod 16 can limit one group of protective film winding storage rollers 6 on the corresponding assembly fixed shaft 5, and the second limiting rod 18 can limit another group of protective film winding storage rollers 6 on the corresponding assembly fixed shaft 5, but the first limiting rod 16 and the second limiting rod 18 will not affect the rotation of the protective film winding storage roller 6, thereby preventing the protective film winding storage roller 6 from being offset during use;

[0044] The cross-sectional shape of the through rod 17 is semicircular, and the through rod 17, the first limiting rod 16 and the second limiting rod 18 are made in an integrated manner to ensure the strength during use. When the pressing and conveying roller 11 is adjusted upward to the limit height by rotating the adjusting rod 7, the first limiting rod 16 then drops to release the restriction on the corresponding protective film winding and storage roller 6, and the through rod 17 is just aligned with the other group of protective film winding and storage rollers 6 at this time. At this time, the center of the through rod 17 is on the central axis of the group of protective film winding and storage rollers 6, and the circumference of the through rod 17 is greater than the circumference of the group of protective film winding and storage rollers 6, so that the longitudinal movement restriction of the group of protective film winding and storage rollers 6 is also released at this time. At this time, the staff can quickly and conveniently disassemble or assemble the two groups of protective film winding and storage rollers 6. Further, at this time, the pressing and conveying roller 11 is at the maximum height, which is convenient for the staff to further manually pull the protective film on the protective film winding and storage roller 6 and preliminarily bond it to the pearl cotton after the protective film winding and storage roller 6 is assembled;

[0045] It should be noted that the first limiting rod 16, the passing rod 17 and the second limiting rod 18 are located between the two groups of conveyor belt assemblies 4, and the entire movable stroke of the first limiting rod 16, the passing rod 17 and the second limiting rod 18 will not interfere with the conveyor belt assembly 4. Furthermore, the first limiting rod 16 will completely release the restriction on the corresponding protective film winding and storage roller 6 only when the special-shaped movable rod 9 drives the pressing conveying roller 11 to rotate to the maximum height. Similarly, only at this time will the passing rod 17 complete the center of the circle on the central axis of the corresponding protective film winding and storage roller 6. Therefore, during other strokes, the protective film winding and storage roller 6 is always restricted on the corresponding assembly fixed shaft 5, so that when the pressing conveying roller 11 adjusts the appropriate height to complete the film coating task of the pearl cotton of different heights, the protective film winding and storage roller 6 is always restricted from longitudinal movement.

[0046] Working principle of the present invention: the device is powered by an external power supply, and the operating installation shaft 20 is rotated. As mentioned above, the adjusting rod 7 can be rotated accordingly, and the height of the pressing and conveying roller 11 is adjusted accordingly. The height of the pressing and conveying roller 11 is adjusted to the maximum amplitude, and the protective film winding storage roller 6 corresponding to the width of the batch is inserted into the corresponding assembly fixed shaft 5 through the protective film assembly hole 3, and the pearl cotton is pulled and placed on multiple groups of conveyor belt components 4, and it is ensured that one side of the pearl cotton and the installation vertical plate 2 close to the side of the worm gear 8 are mutually restricted, and then the protective films on the two groups of protective film winding storage rollers 6 are manually pulled and bonded to the top and bottom of the pearl cotton. Since the pressing and conveying roller 11 is at the maximum height at this time, there is a large operating space, and the operation is convenient and quick;

[0047] After the above operation is completed, the operating installation shaft 20 is rotated again to adjust the height of the pressing and conveying roller 11 until the pressing and conveying roller 11 is pressed and squeezed with the top of the pearl cotton. Further, the threaded rod 12 is rotated. As mentioned above, the special-shaped movable rod 9 can move longitudinally along the threaded rod 12 until the blocking sleeve 10 forms a restriction on one side of the pearl cotton. At this time, since the pressing and conveying roller 11 is no longer at the maximum height, the first limiting rod 16, the through rod 17 and the second limiting rod 18 restrict the two groups of protective film winding and storage rollers 6, thereby preventing the pearl cotton or the protective film winding and storage rollers 6 from deviating during subsequent operations, and completing the assembly and debugging tasks;

[0048] After the assembly and debugging tasks are completed, the conveyor belt assembly 4 and the drive motor 15 are turned on to drive the pearl cotton to move continuously, and the protective film on the protective film winding storage roller 6 is continuously bonded to the corresponding side of the pearl cotton, thereby completing the double-sided lamination task.

[0049] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
