Problems solved by technology

[0014] 1. Domestic automatic tension control device (system): the oil cylinder is automatically tensioned, and the automatic tension control range is small, so it is impossible to realize the whole process and continuous tension control
The pressure balance of the hydraulic system has a large range of changes, the automatic tension control is not accurate, and the stability is poor
The whole part is scattered, the control links are many, and the installation is complicated
The tensioning mode is simple, there are only two control modes, manual and automatic, and the automatic winding function cannot be realized
[0015] 2. Foreign automatic tension control device (system): Although it can provide full-range, continuous and relatively stable tension control, but the electric-hydraulic dual control link, the response of winch tension control is slow
Due to the existence of the hydraulic system, disassembly and maintenance are more complicated
There is no tension control ability after power failure. When the tape machine stops abnormally, the balance and release of tension cannot be achieved, which often causes damage to the winch itself or the tape machine system.

Abstract

The invention discloses a full-automatic winch take-up system, which comprises an electromagnetic braking take-up winch, an auxiliary tension device, a detection system and a take-up control system. The detection system comprises a tension sensor and a transmitter. The auxiliary tension device is connected with the tension sensor, and the detection system is connected with the take-up control system. A combination control switch of the winch of the take-up control system is connected with an electromagnetic brake of an electromagnetic brake motor of the electromagnetic braking take-up winch and a take-up motor, and the electromagnetic brake is connected with the axis of the take-up motor and a coupling. The full-automatic winch take-up system has the advantages of simple control link and faster response of the winch and the control system; and the tension device has the overall tension control and protection functions after the interruption of a power supply. The electromagnetic braking take-up winch and the take-up control system have faster, more stable and accurate tension control; the tension control and protection functions of the tensioning system after the interruption of the power supply is increased simultaneously; and a belt conveyor is designed to be more reasonable and economic.

Description

technical field [0001] The invention relates to a tensioning system, in particular to a fully automatic winch tensioning system. Background technique [0002] At present, the tensioning winch or automatic hydraulic tensioning device used in the tape machine in China cannot provide a continuous, accurate and stable tension guarantee for the tape machine when it starts, runs or stops. Even if it is a fully automatic hydraulic tensioning device, its concept of "automatic tension control" can only be realized within a certain range, and there is a problem of large fluctuation range under the state of automatic tension adjustment, while the overall layout is fragmented and the control system is limited. The complexity makes disassembly extremely inconvenient. Such tensioning winches or automatic hydraulic tensioning devices are all "single tensioning" devices. Therefore, it is not suitable for telescopic or long-distance fixed tape machines. [0003] The most advanced tensioni...
