Description

Technical Field

[0001] The utility model relates to a double-sided adhesive tape, in particular to a ring-shaped double-sided adhesive tape with the functions of pulling adhesive and tearing film. Background Art

[0002] Double-sided adhesive material is a roll of adhesive tape made by evenly coating an elastomeric pressure-sensitive adhesive or a resin-based pressure-sensitive adhesive on a paper, cloth, or plastic film substrate. It consists of three parts: substrate, adhesive, and release paper (film). Double-sided tape can be divided into solvent-based adhesive tape (oil-based double-sided tape), emulsion-based adhesive tape (water-based double-sided tape), hot-melt adhesive tape, calendered adhesive tape, and reactive adhesive tape based on the adhesive properties. Double-sided tape is used in the assembly of electronic components to achieve waterproof and dustproof effects. It is wrapped in two layers of protective film, which must be removed before assembly. Double-sided tape is coated in a certain shape with narrow edges. After the protective film is removed, the equipment automatically adjusts the position of the double-sided tape and the product for bonding. The effectiveness of tearing off the protective film determines the quality of the double-sided tape bonding.

[0003] When using existing annular double-sided tape, it is generally necessary to manually tear the film, which has low tearing efficiency and is not conducive to use. Some devices with auxiliary tearing devices have complex structures and high use costs. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the existing technology, the utility model provides a ring-shaped double-sided adhesive tape with the function of pulling glue and tearing film, which effectively solves the problem that the existing ring-shaped double-sided adhesive tape generally needs to be manually torn off the film when in use, the tearing efficiency is low, and it is not conducive to use. Some equipment with auxiliary film tearing has a complex structure and high cost of use.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: the present invention comprises a base provided at the bottom, a first bracket mounted at the rear end of the base, and a double-sided rubber roller placed at the top end of the first bracket, further comprising an axis groove, double-sided tape, and an auxiliary mechanism, wherein the double-sided tape is wound around the double-sided rubber roller, and the auxiliary mechanism is mounted on one side of the first bracket;

[0006] The auxiliary mechanism includes a second bracket, a winding roller, a crank handle, a disc, spiral teeth, a limiting tooth block, a rotating shaft, a spring and a fixed block. The second bracket is fixed to the base, and a winding roller is installed on the top and bottom of the second bracket. A crank handle is installed at one end of the winding roller. The winding roller is located on the outside of the second bracket and is installed with a disc. Spiral teeth are provided at the edge of the disc, and a limiting tooth block is provided on one side of the spiral teeth. One end of the limiting tooth block is connected to the second bracket through the rotating shaft, a spring is installed on one side of the limiting tooth block, and one end of the spring is provided with a fixed block fixed to the second bracket.

[0007] Preferably, a plurality of suction cups are installed at the bottom end of the base.

[0008] Preferably, an axis groove is provided in the middle of the top end of the first bracket.

[0009] Preferably, the winding roller at the top end of the second bracket can only rotate clockwise.

[0010] Preferably, the winding roller at the bottom end of the second bracket can only rotate counterclockwise.

[0011] Preferably, the limiting tooth block limits the rotation of the disc and the spiral teeth.

[0012] Beneficial effect: When the present invention is in use, the double-sided adhesive roller is placed in the shaft groove opened on the first bracket, and the isolation film on both sides of the double-sided adhesive end is torn off, the upper one is wound around the upper winding roller, and the lower one is wound around the lower winding roller. In this way, when tearing the double-sided adhesive film, it can be pulled to the left. The pulled film can be wound on the winding roller by turning the handle. The rotation of the handle drives the upper winding roller to rotate clockwise, and the rotation of the handle drives the lower winding roller to rotate counterclockwise, so that the torn film can be wound on the winding roller. The provided disc, spiral teeth and limiting tooth block are used to limit the winding roller when tearing the film, which is convenient for use.

[0013] The utility model has a novel structure and an ingenious conception, is convenient for tearing off the double-sided adhesive film, has a simple overall structure, low use cost, occupies a small volume, and is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS
