Convenient type self-shearing polyvinyl chloride (PVC) electrical insulating tape

Abstract

The invention discloses convenient type self-shearing polyvinyl chloride (PVC) electrical insulating tape, and relates to the technical field of insulating tape. The convenient type self-shearing PVC electrical insulating tape comprises a tape body which is connected with a fixing plate, and the fixing plate is connected with a connecting device which is connected with a shearing device. The shearing device comprises an upper tool rest, an upper rotating head, a blade rotating rod, a rotating tool rest, an upper blade, a lower tool rest, a lower rotating head and a lower blade. The connecting device is connected with the upper rotating head and the lower rotating head. The upper tool rest is hinged to the upper rotating head, the rotating tool rest is arranged on the upper tool rest, and the upper blade is connected to the rotating tool rest. The lower tool rest is hinged to the lower rotating head and connected with the lower blade. According to the convenient type self-shearing PVC electrical insulating tape, cutting-off of the insulating tape and shearing correction of the width of the insulating tape can be achieved without carrying an extra shearing tool, and the electrical insulating tape is convenient and quick to use; tools cannot be lost, and staff are not prone to being hurt.

Description

technical field [0001] The invention relates to the technical field of insulating tapes, in particular to a portable self-cutting PVC electrical insulating tape. Background technique [0002] Insulating tape specifically refers to the tape used by electricians to prevent leakage and perform insulation. Also known as insulating tape and tape, it consists 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 plus tackifying resin and other compounding agents, with good viscosity and excellent insulation performance. Insulating tape has good insulation and voltage resistance, flame retardant, weather resistance and other characteristics, and is suitable for wire connection, electrical insulation protection and other characteristics. [0003] When using insulating tape to fix joints, in order to ensure the safety of electricity use, it is often ...
