Description

Technical Field

[0001] The utility model relates to a polymer decorative film winding device, in particular to a polymer decorative film winding device applied in the winding device field. Background Art

[0002] Polymer decorative film winding equipment is a specialized device specifically designed for winding polymer decorative film. It plays an important role in the production and processing of decorative materials, efficiently forming decorative film into rolls that are convenient for storage, transportation, and subsequent use.

[0003] The specification of Chinese patent CN221853587U discloses a stretch film rewinding device, including a machine body and an automatic cutting device. Slide grooves are provided at the bottom of both sides of the machine body. After the reel drum is rewound, the automatic cutting device arranged above the machine body automatically cuts the material between the unwinding drum and the reel drum, avoiding accidental scratches and other injuries that are easily caused when the current device is used and the material is cut by a manual handheld knife.

[0004] If the polymer decorative film winding equipment does not have a limit stop mechanism at both ends during the winding process, the film is prone to positional deviation. As the winding progresses, this deviation may gradually increase, resulting in uneven edges of the film roll. The film may gradually tilt to one side during the winding process, resulting in an irregular shape of the wound film roll, affecting the final product. Summary of the Invention

[0005] In response to the above-mentioned prior art, the present invention aims to address the technical problem that, if polymer decorative film winding equipment does not have limit stops at both ends during the winding process, the film material is prone to positional deviation. As the winding progresses, this deviation may gradually increase, resulting in uneven edges of the film roll. The film material may gradually tilt to one side during the winding process, resulting in an irregular shape of the wound film roll, which affects the final product quality.

[0006] In order to solve the above problems, the utility model provides a polymer decorative film winding device, including processing equipment, the left and right inner walls of the processing equipment are symmetrically installed with tightening rollers, the front end of the processing equipment is installed with a pressing roller, and the front end of the processing equipment is provided with a pair of supporting side frames extending out of the processing equipment, the two supporting side frames are detachably connected with a receiving roller located on the outside of the pressing roller, the outer end of the receiving roller is symmetrically provided with a limiting side ring assembly on the left and right sides, the outer end of the limiting side ring assembly is installed with a plurality of self-resetting rotating shafts, and the plurality of self-resetting rotating shafts are equidistantly arranged in a ring shape, the outer end of the shifting arc outward expansion piece is rotatably connected to the shifting arc outward expansion piece, the outer side of the limiting side ring assembly is fixedly connected to the electromagnetic outer ring layer, and the end of the shifting arc outward expansion piece close to the electromagnetic outer ring layer is fixedly connected to the metal inner surface layer.

[0007] In the above-mentioned polymer decorative film winding equipment, when the processing equipment in this scheme winds the film material outside the material receiving roller, the multiple arc-shaped outward extension pieces outside the limiting side ring assembly expand into a large circle with the centrifugal force of the rotation state. The two limiting side ring assemblies can accurately limit the position of the film material at the beginning of winding to prevent the film material from offset.

[0008] As a further improvement of the present application, film material passes through the two tightening rollers, the film material is wound around the outside of the receiving roller, and the film material is located between the two limiting side ring assemblies.

[0009] As a further improvement of the present application, a plurality of supporting symmetrical frames are provided at one end of the two gear arc-shaped outward extension pieces close to each other, and the inner ends of the supporting symmetrical frames are rotatably connected to contact rollers.

[0010] As a further improvement of the present application, the ends of the two gear arc-shaped outward extension pieces that are close to each other are each provided with a side inner groove, and the inner side wall of the side inner groove is fixedly connected to an elastic member.

[0011] As another improvement of the present application, a U-shaped inner frame layer is fixedly connected to one end of the supporting symmetrical frame close to the elastic member, and a pair of contact sensors are fixedly connected to one end of the U-shaped inner frame away from the supporting symmetrical frame.

[0012] As another improved supplement of the present application, the contact sensor contacts the inner wall of the inner side groove, and the elastic member is located on the inner side of the U-shaped inner frame layer.

[0013] As another improved supplement of the present application, the outer sides of the pressing roller shaft and the receiving roller shaft are fitted to each other, and the pressing roller shaft is rotationally connected to the processing equipment.

[0014] In summary, in this scheme, when the processing equipment winds the film material around the receiving roller, the multiple gear arc-shaped outward expansion pieces outside the limiting side ring assembly expand into a large circle with the centrifugal force of the rotating state. The two limiting side ring assemblies can accurately limit the position of the film material at the beginning of winding to prevent the film material from offsetting, and when the supporting side frame stops, the metal inner layer can automatically fall down. At this time, the electromagnetic outer ring layer is energized to magnetically connect the metal inner layer in the gear arc-shaped outward expansion piece with the electromagnetic outer ring layer, so that the finished roll material can be smoothly moved out, making the film material retraction and release process more stable. At the same time, when the gear arc-shaped outward expansion piece contacts and limits the side of the film material, a contact roller rotating outside the supporting symmetrical frame can be set on the inner side of the gear arc-shaped outward expansion piece. The rolling friction coefficient is much smaller than the sliding friction coefficient, thereby greatly reducing the friction on the side of the film material. This can effectively reduce the risk of the film material being scratched and worn during the limiting process, thereby ensuring the surface quality of the film material.

[0024] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0025] The first implementation method:

[0026] Figure 1-5 A polymer decorative film winding device is shown, including a processing device 1, on which tightening rollers 2 are symmetrically installed on the left and right inner walls of the processing device 1, a pressing roller 3 is installed at the front end of the processing device 1, and a pair of supporting side frames 4 extending out of the processing device 1 are provided at the front end of the processing device 1, and the two supporting side frames 4 are detachably connected to a receiving roller 5 located on the outside of the pressing roller 3, and the outer ends of the receiving roller 5 are symmetrically provided with limiting side ring assemblies 6 on the left and right sides. The outer ends of the limiting side ring assemblies 6 are provided with multiple self-resetting rotating shafts 8, and the multiple self-resetting rotating shafts 8 are equidistantly arranged in a ring shape, the outer ends of the shifting arc outward expansion pieces 7 are rotatably connected to the shifting arc outward expansion pieces 7, the outer sides of the limiting side ring assemblies 6 are fixedly connected to the electromagnetic outer ring layer 9, and the end of the shifting arc outward expansion piece 7 close to the electromagnetic outer ring layer 9 is fixedly connected to the metal inner surface layer 10.

[0027] Figure 1-5 It is shown that there is film material passing through the two tightening rollers 2, the film material is wound around the outside of the receiving roller 5, and the film material is located between the two limiting side ring assemblies 6. A plurality of supporting symmetrical frames 11 are provided at one end close to each other of the two gear arc-shaped outward extension pieces 7, and the inner end of the supporting symmetrical frame 11 is rotatably connected to the contact roller 12, the pressing roller 3 and the outer side of the receiving roller 5 are in contact with each other, and the pressing roller 3 is rotatably connected to the processing equipment 1.

[0028] Figure 1-5 It is shown that when the processing equipment 1 in this scheme winds the film material around the outside of the material receiving roller shaft 5, the material receiving roller shaft 5 is quickly rotated on the outside of the material receiving roller shaft 5 by an external driving mechanism to rewind it. During the rapid rotation of the material receiving roller shaft 5, multiple gear arc-shaped outward expansion pieces 7 outside the limiting side ring assembly 6 are expanded into a large circle by the centrifugal force of the rotating state. The two limiting side ring assemblies 6 can accurately limit the position of the film material at the beginning of winding to prevent the film material from deflecting, and when the supporting side frame 4 stops, the metal inner surface layer 10 can automatically fall down. At this time, the electromagnetic outer ring layer 9 is energized to make the metal in the gear arc-shaped outward expansion piece 7 expand. The inner surface layer 10 is magnetically connected to the electromagnetic outer ring layer 9, so that the finished roll material can be smoothly removed, making the film material retraction process more stable, which is not only beneficial to subsequent processing and use, but also can improve the overall quality of the product. At the same time, when the gear arc-shaped outward expansion piece 7 contacts and limits the side of the film material, a contact roller 12 rotating outside the supporting symmetrical frame 11 can be set on the inner side of the gear arc-shaped outward expansion piece 7. The rolling friction coefficient is much smaller than the sliding friction coefficient, thereby greatly reducing the friction on the side of the film material. This can effectively reduce the risk of the film material being scratched and worn during the limiting process, and ensure the surface quality of the film material.

[0029] The second implementation method:

[0030] Figure 6-7 A polymer decorative film winding device is shown, in which two gear arc-shaped outward extension pieces 7 are provided with side inner grooves 13 at the ends close to each other, and the inner side walls of the side inner grooves 13 are fixedly connected with elastic parts 14. The end of the supporting symmetrical frame 11 close to the elastic part 14 is fixedly connected with a U-shaped inner frame layer 15, and the end of the U-shaped inner frame layer 15 away from the supporting symmetrical frame 11 is fixedly connected with a pair of contact sensors 16. The contact sensors 16 are in contact with the inner side walls of the side inner grooves 13, and the elastic part 14 is located on the inner side of the U-shaped inner frame layer 15.

[0031] Figure 6-7As shown, the contact roller 12 can cooperate with the inner side groove 13 outside the gear arc-shaped outward expansion piece 7. The contact rollers 12 at different positions can also be squeezed into the inner side groove 13 at the corresponding position as the thickness of the film material increases during the winding process with different thicknesses of the film material, so that the contact sensor 16 at the end of the supporting symmetrical frame 11 contacts the inner side wall of the inner side groove 13. When different contact sensors 16 are squeezed and reminded, a material removal reminder can be issued, so that the operator can accurately judge the thickness of the film roll to avoid over-winding. The operator can stop winding at the right time and perform the material removal operation in time, thereby improving production efficiency.

[0032] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
