Binding wire length check mechanism of binder

Abstract

A detection and control mechanism for the length of bundling wires of a bundling machine comprises a bracket, pinch rollers and a shaft, and is characterized in that: three supporting rollers are fixedly arranged inside a lateral plate of the bracket by a shaft housing and the shaft; a pair of pinch rollers is placed above the three supporting rollers and fixedly arranged inside an equalizing frame by the shaft; the equalizing frame is fixed at the middle part of the left end of a front pressure lever by the shaft; the front pressure lever is fixedly arranged between two plates of the bracketby keys and the shaft; a rear pressure lever is fixedly arranged at one end of the shaft by keys; the other end of the rear pressure lever is connected with the lower end of a tightening screw by a pin shaft; the upper end of the tightening screw is connected with the lateral plate of the bracket by a adjusting nut; and a measuring encoder is arranged at the side of the second supporting roller by the shaft and the shaft housing and fixed on the lateral plate of the second supporting roller by an encoder bracket, and the bundling wire is arranged among the supporting rollers and the pinch rollers. The detection and control mechanism has simple structure and accurate control precision, and avoids the waste of the bundling wire.

Description

Technical field: [0001] The invention belongs to the technical field of packaging machinery, and in particular relates to a wire length inspection and control mechanism of a hot-rolled narrow strip steel strapping machine. Background technique: [0002] The existing baler is mainly composed of a base, an oil cylinder, a sliding trolley, a wire feeding mechanism, a wire drawing mechanism, a wire cutting mechanism, a hydraulic motor, a pinch wheel, upper and lower cutters, a twisting mechanism, and a wire rope path. The disadvantage of this device is: due to its structural limitations, most of it is not suitable for the bundling of hot-rolled strip coils. Under the action of high heat radiation at a temperature of about 700 degrees, the components are too close to the heat source to easily produce high-temperature radiation annealing, resulting in equipment Low working life and poor use effect. Since most of the bar tying machines adopt a closed threading channel structure, it is ...

AI Technical Summary

Problems solved by technology

[0002] The existing baler is mainly composed of a base, an oil cylinder, a sliding trolley, a wire feeding mechanism, a wire drawing mechanism, a tying wire shearing mechanism, a hydraulic motor, a pressing wheel, an upper and a lower cutter, a kink mechanism, a tying wire channel and other components. The disadvantage of this kind of device is: due to the limitation of its structure, most of them are not suitable for bundling of hot-rolled steel strips and steel coils. Under the action of high heat radiation at a temperature of about 700 degrees, it is easy to produce high-temperature radiation annealing when the parts are too close to the heat source, resulting in equipment Low working life and poor use effect

Because most of the bar balers adopt a closed threading channel structure, it is impossible to thread the tying wire into the inner hole of the strip steel coil through the line channel, and the packaging and binding of the hot-rolled narrow strip steel coil are all manually operated, and the length of the tying wire is difficult. control, which often leads to waste due to excessive length of tying wire, and also affects the quality of baling of steel
