Wire storing device

Abstract

The invention discloses a wire storing device, which comprises a fixed part, a driving wire wheel set and a driven wire wheel set. The driving wire wheel set is provided with a plurality of driving wire wheels and a driving pivot. The plurality of driving wire wheels are assembled on the driving pivot. The driven wire wheel set is provided with a plurality of driven wire wheels and a driven pivot. The plurality of driven wire wheels are assembled on the driving pivot. One end of the driving pivot is fixed on the fixed part. The driving pivot and the driven pivot are arranged in parallel. The driven wire wheel set is below the driving wire wheel set. The wire storing device is characterized by comprising driving and speed-adjusting equipment which is used for driving the driving wire wheels and controlling the rotation speed of the driving wire wheels. The wire storing device disclosed by the invention is high in wire storing capacity. Furthermore, the wire quality can be ensured after wires are stored.

Description

Technical field [0001] The invention relates to a cable storage device, in particular to a cable storage device with large storage capacity and capable of ensuring the quality of the cable after the storage. Background technique [0002] In the cable production process, a wire storage device is needed. The wire storage device stores the wire when the wire pay-off reel is discharged. The purpose is to prepare for the reel replacement. When the reel is empty, the reel needs to be changed. The cable storage device spits out the cable, which can avoid the production stop caused by the change of the pay-off reel, thereby ensuring the large-scale continuous production of the cable. Similarly, the wire depositing device can also be used in the case of a wire depositing disk for changing disks, that is, the wire depositing device spits out the wire when the wire is stored, and the wire depositing device performs storage when the wire is full and then swaps. line.

Problems solved by technology

[0004] However, the wire storage capacity of the above-mentioned wire storage device is relatively small. In order to increase the wire storage capacity of this kind of device, people take the method of increasing the number of main wire reels in the main wire reel group and the number of slave wire reels in the slave wire reel group. Since all the main wire wheels and slave wire wheels are idler pulleys, they need to be rotated under the action of cable tension. To make a larger number of main wire wheels and slave wire wheels rotate, a greater cable tension is required. With stretchability, the increase of cable tension causes the elongation of the cable, and the diameter of the cable becomes thinner, so that the cable after storage does not meet the quality requirements; second, the increase of cable tension causes the cable to press on the wire wheel As the pressure N increases, the friction coefficient u between the cable and the wire wheel remains unchanged. According to the friction calculation formula f=uN, the friction force between the cable and the wire wheel increases, which causes the outer insulation of the cable to wear, Scratched phenomenon
