Lifting device for woven bag of circular weaving machine

Abstract

The invention provides a lifting device for a woven bag of a circular weaving machine. The lifting device comprises a lifting roller, a supporting frame, a driving device, a photoelectric sensor, a PLC and a dust exhaust device. The lifting roller is arranged at the upper end of the supporting frame, the two ends of the lifting roller are fixedly connected with the supporting frame in a rotatable mode, the driving device comprises a motor and a gear set, a gear of the gear set of the driving device is connected with one end of a roller shaft of the lifting roller, the photoelectric sensor is arranged at the other end of the lifting roller, the photoelectric sensor is connected with one end of the PLC, the other end of the PLC is connected with the motor of the driving device, and the dust exhaust device is fixed on the supporting frame and located below the lifting roller. The lifting device has the advantages of being capable of adjusting the rotation speed of the lifting roller in real time and improving the product quality.

Description

technical field [0001] The invention relates to the field of plastic weaving tools, in particular to a lifting device for weaving bags of a circular loom. Background technique [0002] In the production process of plastic woven bags, while the circular loom rotates, the hoisting roller of the circular loom continuously lifts the woven woven bag through rotation, thereby completing the weaving process. However, the rotation of the hoisting roller is driven by a multi-stage gear set. There will be errors in the process, resulting in uneven lifting speed, uneven width of weft threads, repeated weaving, and affecting product quality. In the prior art, photoelectric sensors are generally installed on the motor to regulate the motor speed. However, the photoelectric sensors are installed on the circular The lower part of the loom, because the hairs and dust generated during the working process of the circular loom will fall on the photoelectric sensor, if it is not cleaned for a l...
