Floating pay-off rack and pay-off device

Abstract

The invention relates to a floating pay-off rack. The floating pay-off rack comprises a column, a horizontal shaft arranged on the column, a bushing rotatably connected on the horizontal shaft in a sleeving manner and a pulley assembly arranged below the bushing. The pulley assembly comprises a pulley and a pulley mounting shaft, one end of the pulley mounting shaft is rotatably connected to the bushing through a connecting rod while the pulley is mounted at the other end of the pulley mounting shaft, the pulley is rotatably connected to the pulley mounting shaft, a protecting hood is also arranged on the outer side of the pulley, the protecting hood comprises a guide barrel, an arc-shaped barrel and a front baffle plate and a back baffle plate arranged at two ends of the arc-shaped barrel, the central axis of the guide barrel is aligned to the upper part of a pulley groove in height, and both the front baffle plate and the back baffle plate are rotatably connected to the pulley mounting shaft through bearings. The invention also relates to a multi-path pay-off device adopting the floating pay-off rack, so that wear of copper wires can be reduced to the maximum extent, the copper wires are prevented from intertwining, the problem of copper wire jumping is solved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a floating pay-off rack and a pay-off device, in particular to a floating pay-off rack and a pay-off device for drawing copper wires. Background technique [0002] In the copper wire production process, it is generally necessary to form a thin copper wire through large drawing, medium drawing and small drawing of the copper rod. In the middle drawing or small drawing process, usually a drawing machine has to draw multiple groups of copper wires at the same time, and the copper wires need to be unwound in front of the drawing machine and then sent to the drawing machine in bundles formed by a pay-off frame. Each single-ended wire needs to be pulled out in a spiral form from the wire cage, through the single-ended wire pulley, the wire support frame, and then to the bundled wire frame. The existing wire pulley is an ordinary pulley, which often jumps out of the groove due to the twisting of the wire in the wire cage; in addition...

AI Technical Summary

Problems solved by technology

The existing wire pulley is an ordinary pulley, which often jumps out of the groove due to the twisting of the wire in the wire cage; in addition, the bundled wire rack adopts multiple pulleys arranged side by side, and the copper wire often jumps out of the pulley due to the jump of the wire rod , and then cause problems such as broken wires or wire-to-wire entanglement, wire jamming, etc., which will stop production

[0003] The invention patent with the application number of 201420858653.9 discloses a multi-channel copper wire pay-off device, including a pay-off platform, and the pay-off platform is provided with a plurality of floating pay-off racks and bundled wire racks, and the floating pay-off rack and bundled wire racks There is also a wire support frame between the wire frames. The floating pay-off frame includes a trumpet-shaped wire barrel and a pulley. The pulley is installed on the mounting plate. The mounting plate is hinged with the pillar. The spiral comes out of the wire cage, passes upward through the guide cylinder, passes through the pulley, passes through the wire support frame in the horizontal direction, and then enters the cluster wire frame. In this way, when the copper wire enters the wire cylinder, the degree of freedom of the guide cylinder is small. It can only rotate along the Z axis, which will cause a certain degree of wear to the copper wire. In addition, after the copper wire comes out of the pulley, because the copper wire is in a loose state, the wire holder will wear the copper wire again.

[0004] The invention patent with the application number 201420858475.X discloses a copper wire drawing multi-channel pay-off rack, including a pay-off rack and a bundled wire rack, and a supporting wire arranged between the pay-off rack and the bundled wire rack The wire support frame here adopts a universal bearing, and the inner hole of the universal bearing adopts a wire support sleeve, and the inner hole of the wire support sleeve is in an arc structure. Wear after coming out, but the structure is complicated, the cost is high, and it does not overcome the wear when the copper wire enters the guide cylinder

[0005] In addition, in the invention patent of 201420858475.X, the wire cages are arranged on both sides of the pay-off platform, and the floating pay-off racks are also arranged on both sides of the pay-off platform. However, each outlet of the floating pay-off rack The positions are different, and each copper wire is parallel to each other, so that the position of the pulley of each floating pay-off frame is different, but the position of the wire cage is in a state of alignment, so it is difficult to ensure that the pulley and the wire cage can be in the state of mutual alignment
