Concentric wrapping device capable of actively releasing belt

Abstract

The invention discloses a concentric wrapping device capable of actively releasing a belt. The device comprises a base and a tension control device body, wherein a first motor is fixedly mounted in the base, a second motor is installed on one side of the first motor, the output shaft of the first motor is connected with an outer belt wheel through a first conveying belt, the output shaft of the second motor is connected with an inner belt wheel through a second conveying belt, and the outer belt wheel is connected with an inner rotary disc through an inner rotary shaft. In the prior art, the existing concentric wrapping device lacks an automatic tension adjusting part, and the pay-off tension cannot be kept in a constant state all the time; and the traditional concentric wrapping device adopts an open-loop mode to control a motor to passively release a belt, so that the tension cannot be monitored and controlled in real time, and the tension cannot be accurately controlled so as not toovercome the problems of the influence of mechanical damping and the like and not to achieve the precise control of small-tension belt release. According to the invention, the problems in the prior art are solved.

Description

technical field [0001] The invention relates to the field of wrapping devices, in particular to a concentric wrapping device for actively releasing tape. Background technique [0002] In the wire and cable production process, the core wire of the wire and cable needs to be wrapped one or more times, which requires the use of a concentric wrapping device, which rotates through a turntable to wrap the tape on the core wire , mainly used for wrapping core wires such as wires, power cables, control cables, and optical cables. However, the existing concentric wrapping device still has some defects when it works. Firstly, the lack of tension automatic adjustment parts does not lead to the fact that the pay-off tension cannot be guaranteed to be in a constant state all the time, so that the wrapping effect is greatly reduced. Secondly, the traditional concentric The winding device adopts an open-loop mode to control the motor to passively unwind the belt, which cannot monitor and ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a concentric wrapping device for actively unwinding the tape, which can solve the problem that the existing concentric wrapping device lacks components for automatic tension adjustment, which does not cause the unwrapping tension to be in a constant state all the time, thereby making the wrapping effect Secondly, the traditional concentric wrapping device uses an open-loop mode to control the motor to passively unwind the belt, which cannot monitor and control the tension in real time, nor can it accurately control the tension, so that it cannot overcome the influence of mechanical damping and other effects, and cannot achieve accurate Control small tension release belt
