Adjustable position guide wheel box device

Abstract

The invention relates to a position-adjustable guide wheel box device. The device comprises a fixed box body, wherein a guide wheel mounting plate is fixed on the upper end surface of the fixed box body; a plurality of guide wheel shaft mounting holes are formed in the guide wheel mounting plate and are waist-shaped holes; guide wheel shafts are mounted in the guide wheel shaft mounting holes through adjusting nuts; guide wheels are rotationally mounted on the guide wheel shafts; and grooves are formed in excircles of the guide wheels. The position-adjustable guide wheel box device has the advantages of low cost, simple structure, convenience in operation and the like; the guide wheel shafts are fixed in the waist-shaped guide wheel shaft mounting holes through the adjusting nuts, and the guide wheel shafts can be moved up and down by the adjusting nuts, so that tensile force is regulated and controlled, the operation is convenient, and the effect is remarkable.

Description

technical field [0001] The invention relates to a guide wheel box device, in particular to a position-adjustable guide wheel box device. Background technique [0002] At present, in the extrusion process, most of the extrusion machines only fix one or several guide wheels between the pay-off frame and the extrusion head to play a supporting role, and this device only plays a supporting role. [0003] The core wire enters the die mouth through the fixed guide wheel. When it deviates from the center position of the die mouth, since the machine head and the guide wheel are fixed, it is impossible to adjust the eccentricity problem, which will cause the core wire to be scratched at the die mouth. The guide wheels between the machine heads are fixed, and the tension in the middle cannot be adjusted, so the core wire will sometimes be tight and sometimes loose, resulting in strands when extruding. Contents of the invention [0004] The purpose of the present invention is to ove...
