Adhesive tape cutting device

Abstract

The invention discloses an adhesive tape cutting device. The adhesive tape cutting device comprises a shell, a movable cavity and elastic filler, wherein the movable cavity is formed in the shell and is matched with the tip of the forefinger of a human body; a T-shaped groove is formed in one side of the shell; a T-shaped block is arranged at the bottom of the T-shaped groove; the tail end of a vertical part of the T-shaped block is provided with a blade; the two ends of the horizontal part of the T-shaped block are also provided with a plurality of rubber blocks, and the rubber blocks are in contact with the inner wall of the shell; the elastic filler is arranged in a gap between the movable cavity and the shell; a joint at the junction of a first section of the finger and a second section of the finger projects outwards through bending of the first section of the foreigner to squeeze the elastic filler in the shell, the elastic filler deforms to push the T-shaped block in the T-shaped groove to displace, and finally the blade protrudes out of a notch of the T-shaped groove, so an electrician can conveniently cut an adhesive tape after wrapping the adhesive tape, and the wire end insulation treatment efficiency is increased.

Description

technical field [0001] The invention relates to the field of power systems, in particular to an adhesive tape cutting device. Background technique [0002] Adhesive tape, also known as insulating tape, specifically refers to the tape used by electricians to prevent leakage and play an insulating role. It has good insulation and voltage resistance, flame retardant, and weather resistance. It is composed of a base tape and a pressure-sensitive adhesive layer. The base belt is generally made of cotton cloth, synthetic fiber fabric and plastic film, etc. The adhesive layer is made of rubber and tackifying resin and other compounding agents. It has good viscosity and excellent insulation performance. It is widely used for wrapping, joints, Electrical work such as insulation and sealing. After multiple wire ends have been wound and tinned, the connection of wire ends in some important wiring areas, such as the main switch and power distribution cabinet, needs to be wrapped with f...

Problems solved by technology

[0003] However, during the winding process of insulating tape and fireproof tape, due to the certain toughness and elasticity of the tape, after the wrapping is completed, the connection between the tape wound on the thread and the tape body is handled. The ordinary electrician's operation method is generally through Brutely tear it or bite it off with your teeth. During the tearing process of the former, there will be a long section of overstretched waste rubber end at the end of the tape, which is a waste of tape, and the excess waste glue end is in the junction box. It will take up a lot of space, making the box very crowded, which is not conducive to the sealing of the box. The latter uses the teeth directly, and the sticky substance on the tape is easy to adhere to the teeth, which is likely to cause discomfort to the electrician and endanger the health of the electrician.
