Belt-retracting device for tightener

Abstract

The invention provides a belt-retracting device for a tightener, and relates to a tightener. The device solves the problems that the prior belt-retracting device for the tightener cannot detect the teThe invention provides a belt-retracting device for a tightener, and relates to a tightener. The device solves the problems that the prior belt-retracting device for the tightener cannot detect the tey and the inner end face of the worm shaft. When the worm shaft moves, the inner end face of the worm shaft can be supported against the sensor, and make the sensor generate signals which correspond ty and the inner end face of the worm shaft. When the worm shaft moves, the inner end face of the worm shaft can be supported against the sensor, and make the sensor generate signals which correspond to the tension of the binding belt. The belt-retracting device has the advantages of simple structure, convenient operation, safe use, intelligence, and the like.o the tension of the binding belt. The belt-retracting device has the advantages of simple structure, convenient operation, safe use, intelligence, and the like.nsion of a binding belt and has instability, troublesome operation, complicated structure, and the like. In the belt-retracting device, a bracket of the tightener is provided with a rotatable belt shansion of a binding belt and has instability, troublesome operation, complicated structure, and the like. In the belt-retracting device, a bracket of the tightener is provided with a rotatable belt shaft of which one end extends out of the bracket. The device comprises a case body, a worm, a worm shaft and a worm wheel, wherein the case body is fixedly connected with the side part of the bracket; tft of which one end extends out of the bracket. The device comprises a case body, a worm, a worm shaft and a worm wheel, wherein the case body is fixedly connected with the side part of the bracket; the worm, the worm shaft and the worm wheel are arranged in the case body; the worm wheel is fixedly connected with the extending end of the belt shaft; the worm is sleeved on and fixedly connected withe worm, the worm shaft and the worm wheel are arranged in the case body; the worm wheel is fixedly connected with the extending end of the belt shaft; the worm is sleeved on and fixedly connected with the worm shaft which is arranged on the side part of the worm wheel and can move in the case body along the axial direction. The device also comprises a sensor which is arranged between the case bodh the worm shaft which is arranged on the side part of the worm wheel and can move in the case body along the axial direction. The device also comprises a sensor which is arranged between the case bod

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a winch and a winch for bundling goods in the process of logistics transportation, in particular to a belt retracting device for a belt shaft in the winch. Background technique [0002] During the transportation of goods, the goods usually need to be bundled to prevent the goods from falling off or colliding with each other during transportation and causing loss or damage. Although the method of directly binding with ropes is very common, it is time-consuming and laborious, and it is difficult to tie the goods tightly. The tightener is an advanced binding tool. It is convenient and safe to use the tightener to bind the goods, and is welcomed by the majority of transport personnel. Existing tighteners are usually made up of support, band shaft and binding band. The tape shaft is connected to the bracket and the tape shaft is rotatable, and the binding tape is wound on the tape ...

AI Technical Summary

Problems solved by technology

[0004] Obviously, although the above-mentioned binding device can realize the control of the belt shaft, the worm is manually controlled by the operator, and the operation is cumbersome and the degree of automation is not high.

In the prior art, although the power mechanism is also used to drive the worm to move, the power mechanism cannot know the tension of the binding belt, and it is difficult to control it during use.

Often it will cause damage to the goods due to excessive binding, break the binding belt, or affect the transportation of goods because the binding is not tight enough

In addition, when binding goods, different goods or the same goods will have different strengths when binding in different positions, which further increases the difficulty of manual control.
