Anti-curling tape core

Abstract

This utility model relates to the field of adhesive tape technology and discloses an anti-curling adhesive tape core, including an adhesive tape core body and an inner core ring located inside the adhesive tape core body. An elastic layer with a honeycomb structure is fixedly installed between the adhesive tape core body and the inner core ring. Reinforcing rings are fixedly installed at the front and rear ends of the inner wall of the inner core ring. This utility model improves the rigidity of the adhesive tape core body by fixing the reinforcing rings and reinforcing rods to the inner side of the inner core ring. When the adhesive tape is wound around the outer side of the adhesive tape core body, generating large pressure or vibration during transportation, the elastic layer between the adhesive tape core body and the inner core ring acts as a buffer. Furthermore, the reinforcing rings and reinforcing rods support the inner side of the inner core ring, avoiding the situation where the adhesive tape core body made of cardboard has weak resistance to deformation, which can cause the adhesive tape core to deform under the pressure of tape winding or transportation vibration, resulting in the tape edge curling and reducing the ease of use of the tape.

[0002] Adhesive tape is an item composed of a substrate and an adhesive. It can connect two or more unconnected objects together through bonding. Adhesive tape can be classified according to its function into high temperature tape, double-sided tape, insulating tape, special tape, pressure-sensitive tape, and die-cut tape. Different functions are suitable for different industry needs.

[0003] In the process of realizing this invention, the inventors discovered at least the following problems in the prior art:

[0004] Existing tapes are stored by wrapping them around the outside of the tape roll core. However, since most tape roll cores are currently made of cardboard, their resistance to deformation is relatively weak. The tape winding pressure or transportation vibration may cause the tape roll core to deform, resulting in the tape edges curling and reducing the ease of use of the tape.

[0005] Therefore, the aforementioned technical problems need to be solved. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an anti-curling tape core, which solves the problem that the main body of the tape core made of cardboard has weak resistance to deformation, which can cause the tape core to deform under tape winding pressure or transportation vibration, resulting in tape edge curling and reduced ease of use of the tape.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] An anti-curling tape core includes a tape core body and a core inner ring located inside the tape core body. An elastic layer is fixedly installed between the tape core body and the core inner ring, and the elastic layer is honeycomb-shaped. Reinforcing rings are fixedly installed at the front and rear ends of the inner wall of the core inner ring, and reinforcing rods are fixedly installed between the reinforcing rings in an axially distributed manner.

[0009] Preferably, a release film layer is fixedly installed on the outer side of the tape core body, and the release film layer is made of polypropylene. The tape body is wrapped around the outer side of the tape core body, and the inner side of the tape body is tightly adhered to the release film layer.

[0010] Preferably, the outer layer inside the tape body is provided with a waterproof layer, and the waterproof layer is made of polyvinyl chloride.

[0013] Preferably, the tape body has a high-temperature resistant layer inside, the high-temperature resistant layer is made of polytetrafluoroethylene, and the bottom layer inside the tape body has a tensile layer located at the bottom of the high-temperature resistant layer.

[0014] Compared with the prior art, this utility model provides an anti-curling tape core with the following beneficial effects: This utility model fixes the tape core body to the inner side of the inner ring by means of a reinforcing ring and a reinforcing rod, thereby improving the rigidity of the tape core body. When the tape is wound around the outer side of the tape core body and generates large pressure or vibration occurs during transportation, the elastic layer located between the tape core body and the inner ring of the core plays a buffering role. In addition, the reinforcing ring and the reinforcing rod support the inner side of the inner ring of the core, avoiding the situation where the tape core body made of cardboard has weak resistance to deformation, which may cause the tape core to deform under tape winding pressure or transportation vibration, resulting in tape edge curling and reducing the ease of use of the tape.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes an anti-rolling tape core.

[0022] Please see Figures 1-4 An anti-curling tape core includes a tape core body 1 and a core inner ring 101 located inside the tape core body 1. An elastic layer 102 is fixedly installed between the tape core body 1 and the core inner ring 101, and the elastic layer 102 is honeycomb-shaped. Reinforcing rings 103 are fixedly installed at the front and rear ends of the inner wall of the core inner ring 101, and reinforcing rods 104 are fixedly installed in an axially distributed manner between the reinforcing rings 103.

[0023] Through the above structural design, the anti-curling tape core improves the rigidity of the tape core body 1 by providing a reinforcing ring 103 and a reinforcing rod 104 on the inner side of the inner ring 101. The elastic layer 102 between the tape core body 1 and the inner ring 101, and the honeycomb shape of the elastic layer 102, plays a buffering role, so that the tape core body 1 will not deform under pressure or vibration during transportation when the tape is wrapped around the outside of the tape core body 1. This avoids the situation where the tape core body 1 made of cardboard has weak resistance to deformation, which may cause the tape core to deform under the pressure of tape winding or vibration during transportation, resulting in the tape edge curling and reducing the ease of use of the tape.

[0024] Furthermore, a release film layer 105 is fixedly installed on the outer side of the tape roll core body 1, and the release film layer 105 is made of polypropylene. A tape body 2 is wound around the outer side of the tape roll core body 1, and the inner side of the tape body 2 is tightly adhered to the release film layer 105. Specifically, by adhering the innermost side of the tape body 2 to the outer side of the release film layer 105, the tape body 2 is wound around the outer side of the tape roll core body 1, avoiding the problem of the tape body 2 being difficult to peel off from the innermost layer of the outer side of the tape roll core body 1.

[0025] Furthermore, a waterproof layer 201 is provided on the outer layer inside the tape body 2, and the waterproof layer 201 is made of polyvinyl chloride. Polyvinyl chloride has good waterproof performance, so that when the outermost layer of the tape body 2 comes into contact with water during use, it will not penetrate to the adhesive layer, thereby preventing the tape body 2 from falling off after being exposed to water;

[0026] Furthermore, an antistatic layer 202 is provided inside the tape body 2, and the antistatic layer 202 is located inside the waterproof layer 201. The antistatic layer 202 provides antistatic treatment to the tape body 2, preventing dust floating in the air from adsorbing onto the surface of the tape body 2 during use, thus avoiding a reduction in the adhesive strength of the tape body 2.

[0027] Furthermore, a flame-retardant layer 203 is provided inside the tape body 2, and the flame-retardant layer 203 is located inside the antistatic layer 202. The flame-retardant layer 203 provides fire protection for the tape body 2, preventing spontaneous combustion due to high temperatures or electronic sparks when the tape adheres to or wraps around the surface of wires or electronic devices.

[0028] Furthermore, the tape body 2 has a high-temperature resistant layer 204 inside, which is made of polytetrafluoroethylene. The bottom layer inside the tape body 2 is a tensile layer 205 located at the bottom of the high-temperature resistant layer 204. The high-temperature resistant layer 204 allows the tape body 2 to maintain high adhesive performance in high-temperature environments, improving the tape's performance. The tensile layer 205 increases the tensile strength of the tape body 2, preventing a decrease in adhesive strength when the tape body 2 is stretched.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
