[0001] The utility model relates to an adjustable laminating machine for packaging films. Background Art

[0002] Laminating technology was born in the 1950s and was first adopted by the US Army. my country's laminating process was inspired by Japanese calendar cards in the mid-1960s, and was successfully tested on printed products and soon widely used. Generally, a special tensioning device is required for laminating, but the existing laminating tensioning device with adjustable tension cannot meet the demand for tension adjustment during laminating, which increases the workload of the staff, is not stable enough during laminating, reduces the quality of the product during laminating, and may cause tearing during laminating.

[0003] The existing laminating machine that can avoid tearing, for example, a laminating tensioning device with adjustable tensioning degree with announcement number CN213201769U, comprises a bottom plate, a tensioning structure and an adjusting tensioning structure; the bottom plate: a U-shaped plate is provided at the left end of its upper surface, a mounting seat 1 is provided in the middle of the rear surface of the U-shaped plate, a motor 1 is provided in the arc-shaped groove at the upper end of the mounting seat 1, a U-shaped plate is provided at the right end of the upper surface of the bottom plate, the interior of the U-shaped plate is rotatably connected to two rotating columns through a rotating shaft, mounting plates are symmetrically provided at the front and rear ends of the upper surface of the U-shaped plate, a mounting seat 2 is provided on the rear surface of the mounting plate on the rear side, and a motor 2 is provided in the arc-shaped groove at the upper end of the mounting seat 2; the tensioning structure: arranged between the two mounting plates, the front end of the output shaft of the motor 2 is fixedly connected to the tensioning structure; the adjusting tensioning structure: arranged inside the U-shaped plate, the front end of the output shaft of the motor 1 is fixedly connected to the adjusting tensioning structure; the laminating tensioning device with adjustable tensioning degree meets the demand for tensioning adjustment during laminating and improves the quality of the product during laminating.

In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0043] The server provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0044] Embodiment 1:

[0045] like Figure 1 , Figure 2 As shown, an embodiment of the present application provides an adjustable laminating machine for packaging film, including a base plate 1, a bracket 2, a unwinding roller 3, a pressure roller 4, a guide roller 5 and a winding roller 6, and also includes: a clamping unit 7, which is fixedly mounted on the bracket 2; wherein the lower end of the clamping unit 7 is in contact with the winding roller 6.

[0046] Furthermore, the clamping unit 7 includes a mounting plate 8, which is fixedly mounted on the upper end of the bracket 2; a driving assembly 9, which is fixedly mounted on the mounting plate 8; a moving block 10, which is movably mounted on the driving assembly 9; and a pressure plate, which is fixedly connected to the lower end of the moving block 10, and the lower end surface is against the outer wall of the pressure roller 4.

[0047] Furthermore, the driving assembly 9 includes a pair of limit blocks 12, which are respectively fixedly mounted on the bracket 2 and located below the mounting plate 8; a screw rod 13, which is rotatably connected between the limit block 12 on one side and the mounting plate 8 and driven by a motor; a guide rod 14, which is fixedly connected between the limit plate on the other side and the mounting plate 8; wherein the moving block 10 is movably mounted on the screw rod 13 and the guide rod 14.

[0048] In this embodiment of the present application, due to the adoption of the above-mentioned structure, the packaging film is wound up by the winding roller 6. In order to avoid bubbles and creases during the winding process, the outer wall of the winding roller 6 is pressed against the pressing block 11. Since the winding diameter of the winding roller 6 will continue to increase during the winding process, the height of the pressing block 11 will also change. At the same time, the motor drives the screw 13 to rotate, and the moving block 10 drives the pressing block 11 to move upward along the screw 13. The moving block 10 also moves upward along the guide rod 14 to improve the stability of the moving block 10 during movement. The moving block 10 continues to move upward with the increase of the winding diameter of the packaging film on the winding roller 6, ensuring that the pressing block 11 is pressed against the outer end of the packaging film during the winding process at any time. The pressing of the pressing block 11 can avoid bubbles and creases during the winding process.

[0049] Embodiment 2:

[0050] like Figure 1 , Figure 3 As shown, in this embodiment, in addition to the structural features of the previous embodiments, it also includes: a cleaning component 15, which is fixedly mounted on the bracket 2 and located below the guide roller 5.

[0051] Furthermore, the cleaning assembly 15 includes a support plate 16 fixedly mounted on the bracket 2 ; a brush 17 fixedly mounted on the support plate 16 ; and a dust hood 18 fixedly mounted on the support and located behind the brush 17 .

[0052] Furthermore, it also includes a dust box 19 placed on the bottom plate 1 ; a dust suction pipe 20 fixedly connected between the dust hood 18 and the dust box 19 ; and an exhaust fan 21 fixedly connected to the dust box 19 .

[0053] Furthermore, it also includes a filter plate 22 which is fixedly installed in the dust box 19 .

[0054] In this embodiment of the present application, due to the adoption of the above-mentioned structure, the packaging film is transported from the unwinding roller 3, the pressure roller 4 and the guide roller 5 in sequence, and is wound up by the winding roller 6. During the coating process, dust and other impurities will adhere to the packaging film. In order to ensure the cleanliness of the packaging film before winding, a cleaning component is arranged under a pair of guide rollers 5. When the packaging film passes through a pair of guide rollers 5, the guide rollers 5 are parallel to each other, ensuring that the packaging film is in a plane during transportation. The packaging film is first cleaned by a brush 17, and the brush 17 sweeps away the dust and impurities on the packaging film. At the same time, the exhaust fan 21 is started, and the dust suction pipe 20 sucks the swept dust from the dust suction hood 18 into the dust collecting box 19, effectively removing dust from the surface of the packaging film, and a filter plate 22 is arranged in the dust collecting box to filter out impurities to prevent impurities from flying into the exhaust fan 21 and damaging the exhaust fan 21.
