A kind of asphalt coating device for high-voltage cable production

Abstract

The invention provides an asphalt coating device for high-voltage cable production, which relates to the field of high-voltage cable production. The asphalt coating device for high-voltage cable production includes a support box, a power mechanism is fixedly installed on the inside of the support box, a coating mechanism is rotatably connected to the inside of the support box under the power mechanism, and the coating mechanism and the power mechanism are connected by transmission. , the inside of the support box is located at the front end of the smearing mechanism and is rotatably connected with a scraper mechanism, and the scraper mechanism is connected with the power mechanism. The asphalt smearing device for high-voltage cable production can drive the scraper to rotate through the rotation of the driven two-tooth ring, and at the same time, it can drive the scraper to move forward at the same speed as the cable inlet speed during the rotation process through the traction wire. When the ball is in contact with the driven gear, the traction wire can be reset under the action of the reset spring, and the scraper can return to the initial position at this time, which solves the problem of uneven application of the scraper in the prior art.

Description

technical field [0001] The invention relates to the technical field of high-voltage cable production, in particular to an asphalt coating device for high-voltage cable production. Background technique [0002] Cable asphalt is a special petroleum asphalt used for insulation and protection of power cables and communication cables. Black solid. It is characterized by good electrical insulation performance, high breakdown voltage, large adhesion area, strong adhesion, and good waterproof and anti-corrosion performance. [0003] In the process of applying asphalt to the cable, the asphalt is unevenly applied due to gravity. The existing solution is to apply it with a scraper. Since the cable is moving during the production process, the rotation of the scraper and the movement of the cable will cause Textures appear in asphalt smearing, so a new type of asphalt smearing device is needed. SUMMARY OF THE INVENTION [0004] In view of the deficiencies of the prior art, the pres...
