Description

Technical Field

[0001] The utility model belongs to the technical field of winding machines, and particularly relates to a cable insulating tape winding machine. Background Art

[0002] Insulating tape refers to the tape used by electricians to prevent electric leakage and play an insulating role. Also known as insulating adhesive tape or adhesive tape, it consists of a base tape and a pressure-sensitive adhesive layer. The base tape is generally made of cotton cloth, synthetic fiber fabric, plastic film, etc., and the adhesive layer is made of rubber plus tackifying resin and other compounding agents, with good viscosity and excellent insulation performance. The insulating tape has good insulation voltage resistance, flame retardancy, weather resistance and other characteristics, and is suitable for wire connection, electrical insulation, heat insulation protection and other features.

[0003] During the production process of the tape, it is not cut to the required width first and then wound. According to the information provided in the reference article, the typical production process of the tape is as follows: Film blowing: Add plastic masterbatch into the film blowing machine to blow into plastic film, with a width of about 1.3M generally. Different plastic particles are selected according to the use of the tape, and some special additives are added; Glue coating: After film blowing, put the film into the coating machine to add coating glue. This process mainly selects the glue according to the required viscosity and use of the tape, and the basic form of the tape is formed after coating; Rewinding: Then, it is necessary to wind the large roll of plastic film into small rolls through a rewinder. This step can be rewound according to the length of the tape usually used; Cutting: The small rewound film roll can be cut into the width required for ordinary tape by a cutting machine. This step is carried out after rewinding, that is, first wound into a film roll of a certain length and then cut into the required width.
