Description

Technical Field

[0001] This utility model relates to the field of die-cutting technology, specifically to a load-bearing structure for die-cut parts. Background Technology

[0002] In the manufacturing of die-cut parts, after die-cutting, there are two common finished product forms: some are rolled into rolls, while others are sliced. Rolled die-cut parts rely on carrier belts for support. However, in actual production, frequent friction between the carrier belt and the die-cut parts, and between the carrier belt and other components, easily generates static electricity. This static electricity causes the carrier belt and the surface of the die-cut parts to attract a large amount of dust and impurities, affecting not only the appearance quality of the die-cut parts but also their performance. Furthermore, if the winding process is too tight, it applies excessive pressure to the die-cut parts. Combined with the static electricity generated by friction, this can easily lead to problems such as displacement or back-sticking, severely impacting production quality and efficiency, increasing production costs, and reducing product yield. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a load-bearing structure for die-cut parts.

[0004] The purpose of this utility model can be achieved through the following technical solution: a bearing structure for a die-cut part, including a roll and a base film, on which the die-cut part is adhered, and on both sides of the die-cut part are symmetrically provided heightening strips higher than the die-cut part, and the heightening strips are covered with a conductive layer, which abuts against the roll when the part is wound up, and the roll is made of conductive material.

[0005] Preferably, baffles are provided on both sides of the scroll.

[0006] Preferably, the inner wall of the baffle is provided with a conductive sheet that is connected to the roll, and the conductive layer extends to the side of the riser and contacts the conductive sheet during winding.

[0007] Preferably, the two sides of the heightening strip have an arc-shaped structure.

[0008] Preferably, the conductive layer is copper foil.

[0009] Preferably, the copper foil surface is covered with a protective film.

[0010] The beneficial effects of this invention are as follows: by setting a conductive layer on the bottom film and constructing an electrostatic discharge path with the roll, the static electricity generated during the die-cutting process is quickly released, avoiding static electricity accumulation; at the same time, the use of the riser strip higher than the die-cut part provides support, avoiding the direct action of the winding pressure on the die-cut part, overcoming the problems of die-cut part displacement and back-sticking caused by excessive winding and static electricity, significantly improving the production quality and efficiency of die-cut parts, reducing production costs and defect rate, and ensuring the quality and integrity of die-cut parts.

[0015] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0016] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0017] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] See Figures 1 to 2As shown, the structure of this utility model is as follows: a support structure for a die-cut part, including a roll 1 and a base film 2. A die-cut part 3 is adhered to the base film 2. The two sides of the die-cut part 3 are symmetrically provided with raising strips 4 that are higher than the die-cut part 3. The raising strips 4 are covered with a conductive layer 5. The conductive layer 5 abuts against the roll 1 when it is wound up. The roll 1 is made of conductive material. Specifically, in the production process of the die-cut part 3, the conductive roll 1 is installed on the die-cutting machine, and then the base film 2 with the raising strips 4 is fixed on the roll 1. At this time, the conductive layer 5 covering the surface of the raising strips 4 is in close contact with the roll 1. At the same time, the roll 1 is connected to the die-cutting machine. The three together form a complete conductive path. In this process, static electricity is generated by the friction between the base film 2 and the guide rollers of the die-cutting machine, as well as the friction between the layers of material during winding. This static electricity is quickly conducted through the conductive layer 5 to the roll 1, and then from the roll 1 to the die-cutting machine. Finally, the static electricity is safely released to the ground through the grounding wire of the die-cutting machine, thus effectively preventing static electricity accumulation from damaging the die-cut part 3 and preventing the die-cut part 3 from sticking due to static adsorption. During winding, the raised strips 4 on both sides support the die-cut part 3, preventing the pressure during winding from acting directly on the die-cut part 3, thereby effectively preventing displacement or deformation of the die-cut part 3 and ensuring the quality and integrity of the die-cut part 3 in all aspects.

[0019] like Figure 2 As shown, the two sides of the heightening strip 4 have an arc-shaped structure. Specifically, the arc-shaped sides can make the pressure of the heightening strip 4 and the conductive layer 5 more evenly distributed when they are rolled up, avoiding stress concentration at the corners, and helping to reduce the possibility of deformation or damage to the heightening strip 4 and the conductive layer 5 due to excessive local stress.

[0020] like Figure 1 As shown, baffles 6 are provided on both sides of the roll 1. Specifically, when performing operations such as winding, storage or handling, the baffles 6 physically block the bottom film 2, restricting the movement of the bottom film 2 in the horizontal direction to both sides of the roll 1, thereby enhancing the stability of winding.

[0021] like Figure 1 , Figure 2 As shown, the inner wall of the baffle 6 is provided with a conductive sheet 7 connected to the roll 1. The conductive layer 5 extends to the side of the bottom film 2 and the raising strip 4 and contacts the conductive sheet 7 during winding. Specifically, during the winding process, the extended conductive layer 5 will contact the conductive sheet 7, which further expands the contact area and contact path between the conductive layer 5 and the roll 1, making the conductive path smoother. This can significantly improve the efficiency and stability of electrostatic conduction, and more effectively release the static electricity generated by the die-cut part 3 in a timely manner, reducing the potential harm of static electricity to the die-cut part 3.

[0022] Furthermore, the conductive layer 5 is made of copper foil. Specifically, the excellent conductivity of copper foil ensures that static electricity can be efficiently conducted from the die-cut part 3 to the roll 1 and released, guaranteeing a smooth conductive path. In addition, copper foil also has a certain degree of flexibility and corrosion resistance, making it easy to process into the required shape to cover the reinforcing strip 4, and it can maintain good conductivity for a long time under certain environmental conditions.

[0023] Furthermore, the copper foil surface is covered with a protective film, which forms a physical isolation layer that prevents external dust, moisture, oxygen, and other substances from directly contacting the copper foil. This prevents the copper foil from being oxidized, corroded, scratched, or stained during storage, transportation, and when not in use, thus ensuring the flatness and conductivity of the copper foil surface. When needed, simply remove the protective film, and the copper foil will function normally, extending its service life and performance stability.

[0024] In practical use, during the production process of die-cut part 3, a conductive roller 1 is installed on the die-cutting machine. Then, a base film 2 with lifting strips 4 is fixed on the roller 1. The static electricity generated by the friction between the base film 2 and the guide roller of the die-cutting machine, and the mutual friction between the layers of materials during winding, is conducted through the conductive layer 5 to the roller 1, and then transmitted from the roller 1 to the die-cutting machine. Finally, the static electricity is safely released to the ground with the help of the grounding wire of the die-cutting machine, thereby effectively avoiding the accumulation of static electricity that could damage the die-cut part 3 and preventing the die-cut part 3 from sticking due to static adsorption. During winding, the lifting strips 4 on both sides provide support for the die-cut part 3, preventing the pressure during winding from acting directly on the die-cut part 3, thereby effectively preventing the die-cut part 3 from shifting or deforming.

[0025] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
