Deviation correction type uncoiling device having tension control function

Abstract

The invention relates to the field of a coiled material machining device, in particular to a deviation correction type uncoiling device having a tension control function. The deviation correction typeuncoiling device comprises a bracket; two supporting plates are symmetrically installed at the two ends of the bracket; the deviation correction type uncoiling device is characterized in that two sliding bearings are installed at positions, correspondingly positioned on the supporting plates, of the two ends of the bracket; an air expansion shaft is installed between the two sliding bearings; thesupporting plate at one end of the bracket is equipped with a tension brake device; the supporting plate at the other end of the bracket is equipped with a tension driving device; and the supportingplate at one end of the bracket is also equipped with an automatic deviation correcting device. The deviation correction type uncoiling device provided by the invention can maintain a constant uncoiling speed of a coiled material, also has an automatic deviation correction function, improves the product quality and is good in application prospects.

Description

Technical field [0001] The invention relates to the field of coil processing devices, in particular to a correction type unwinding device with a tension control function. Background technique [0002] In the medical auxiliary material processing industry, many raw materials are coils. In actual production, subsequent processing such as uncoiling, fixed distance conveying, sealing, cutting, etc. are required. The uncoiling process is to place the coiled raw materials on a support with a roller. , The coil is unrolled by the traction conveyor and transported to the rear end. [0003] In the prior art, the traction and conveying device is generally provided with a pair of rollers that rotate under the drive of a motor to pull the coil to be conveyed backward. The traction force of the traction and conveying device on the coil is often set to a fixed value, so that the coil The conveying speed is uniform, and the length of the coil conveyed per unit time is kept consistent to meet the...

AI Technical Summary

Problems solved by technology

[0004] However, during the winding process, manufacturers of raw materials for coils often have inconsistent tightness of the coils on the parent roll due to equipment reasons, resulting in inconsistent lengths of the coils delivered by the traction device per unit time during the unwinding process. It leads to unstable cutting at a fixed distance, which seriously affects the product quality of the subsequent process
