Description

Technical Field

[0001] The present application relates to the technical field of winding, and in particular to a method for winding a PVC decorative film. Background Art

[0002] After the PVC decorative film is rolled up, the ends of the PVC decorative film need to be fixed to reduce the probability of it becoming scattered during transportation. The existing rolling method is usually to cut it and then fix it with a cable tie. This method has the risk of squeezing and damaging the PVC decorative film. Summary of the Invention

[0003] In view of the shortcomings of the prior art, one of the objectives of the present application is to provide a PVC decorative film rolling method, which has the advantage of reducing the risk of extrusion damage to the PVC decorative film.

[0004] The above-mentioned purpose of this application is achieved through the following technical solutions:

[0005] A PVC decorative film winding method comprises a punching step of punching a plurality of holes in the PVC decorative film along the width direction, a gluing step of gluing the holes when the holes are moved onto the PVC decorative film on a winding shaft, and a drying step of drying the glued areas.

[0006] By adopting the above technical solution, in production, multiple holes are punched in the width direction of the PVC decorative film, and then glue is applied. During the gluing process, the glue penetrates into the adjacent PVC decorative films through the holes. After drying, the PVC decorative films are connected, thereby reducing the probability of scattering. At the same time, the risk of squeezing and damaging the PVC decorative film caused by using cable ties can be avoided by connecting with glue.

[0007] In a preferred example, the present application can be further configured as follows: it also includes a marking step, the marking step is located before the piercing step, the marking step is performed along the length direction of the PVC decorative film, the marking is set obliquely, and the length of the mark is greater than the circumference of the PVC decorative film roll.

[0008] By adopting the above technical solution, since the mark is set at an angle and the length of the mark is greater than the circumference of the PVC decorative film roll, after being rolled up, the mark is spiral-shaped, and the two ends of the mark are the glue joints, thereby enabling users to quickly identify the ends of the PVC decorative film.

[0009] In a preferred example, the present application can be further configured as follows: it also includes a splicing step, splicing the PVC decorative film on both sides of the marking area, and then rolling it up. After the drying step, there is a transfer step, in which the rolled PVC decorative film is moved a certain distance from the upper position after rolling up, and the spliced decorative film on this side is gathered toward the axis core of the rolled PVC decorative film and stuffed into the axis core, and then it is unloaded from the winding shaft, and the spliced decorative film on the other side is gathered toward the axis center of the rolled PVC decorative film and stuffed into the axis core.

[0010] By adopting the above technical solution, the PVC decorative film is spliced so that after rolling up, the spliced PVC decorative film will exceed the edge of the rolled up PVC decorative film, so that the side edges of the rolled up PVC decorative film can be covered, thereby protecting the side edges. At the same time, since the film is fixed by friction by being inserted into the shaft core, disassembly is also more convenient.

[0011] In a preferred example, the present application can be further configured as follows: in the marking step, the area to be marked is lifted so that the area to be marked is transported in a suspended state and contacts the marking head, and the PVC decorative film is marked as it is transported.

[0012] By adopting the above technical solution, the area to be marked is lifted so that the area to be marked comes into contact with the marking head, thereby achieving the marking function.

[0013] In a preferred example, the present application can be further configured as follows: in the splicing step, when the area to be marked begins to be marked, the PVC decorative film used for splicing is unrolled and placed under the area to be marked, and partially overlaps with the area to be marked; when the marking of the area to be marked is completed, the area to be marked is lowered and bonded to the PVC decorative film used for splicing.

[0014] By adopting the above technical solution, after the area to be marked is lifted, the PVC decorative film for splicing is placed under the area to be marked. As the marking of the area to be marked is completed and it descends, it contacts and bonds with the PVC decorative film for splicing.

[0015] In a preferred example, the present application can be further configured as follows: in the hole-piercing step, the area overlapping with the spliced PVC decorative film is not pierced.

[0016] By adopting the above technical solution, when using PVC decorative film, since there are no holes on both sides of the glued part, after the spliced parts are disassembled, the glued parts can be disconnected by pulling both sides of the glued part, making it easy to use. DETAILED DESCRIPTION

[0017] The present application discloses a method for winding PVC decorative film, comprising the following steps: a marking step, wherein marking is performed along the length of the PVC decorative film, the marking being arranged at an angle, the length of the marking being greater than the circumference of the PVC decorative film roll, and a predetermined length (not less than the circumference of the PVC decorative film roll, where the circumference of the PVC decorative film roll herein refers to the outer circumference of the PVC decorative film roll after the predetermined length of the PVC decorative film roll is wound) of the area to be marked is lifted, so that the area to be marked is conveyed in a suspended state and contacts a marking head, and the PVC decorative film is marked as it is conveyed. The marking head can be a coding device, an inkjet device, a paintbrush, or other structure capable of leaving lines on the surface of the PVC decorative film.

[0018] During the splicing process, when the area to be marked begins to be marked, the PVC decorative film for splicing is unwound and placed below the area to be marked, partially overlapping it. When the area to be marked is completed, the area to be marked is lowered and bonded to the PVC decorative film for splicing. The PVC decorative film used for splicing can be used from defective products produced during the production process, which is more energy-efficient and environmentally friendly.

[0019] In the piercing step, a plurality of holes are pierced in the width direction of the PVC decorative film, and the area overlapping with the spliced PVC decorative film is not pierced. In the gluing step, when the holes are moved to the PVC decorative film on the winding shaft, glue is applied to the holes. In the drying step, the glued areas are dried.

[0020] The transfer step is to move the rolled PVC decorative film a certain distance from the upper position after rolling, gather the spliced decorative film on this side to the axis core of the rolled PVC decorative film, and insert it into the axis core, then unload it from the winding shaft, gather the spliced decorative film on the other side to the axis center of the rolled PVC decorative film, and insert it into the axis core.

[0021] The implementation principle of this embodiment is: through the above-mentioned arrangement, the end of the PVC decorative film can be fixed, and at the same time, both sides of the rolled PVC decorative film can be protected.

[0022] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
