Device for mounting sleeve on coiler mandrel

Abstract

The invention discloses a device for mounting a sleeve on a coiler mandrel. The device comprises a support upright arranged on a wrapper of a coiler, and a support bracket. The support bracket comprises two supporting steel members parallelly arranged in the transverse direction and two bearing steel members parallelly arranged in the longitudinal direction. One ends of the supporting steel members are rotationally mounted at the support upright of the wrapper. The bearing steel members are arranged at the other ends of the supporting steel members and oppositely inclined relative to the supporting steel members. Two sets of pulleys sliding longitudinally are arranged on the two opposite sides of the two bearing steel members correspondingly. According to the technical scheme provided by the invention, during the mounting of the sleeve, the support bracket rotates around the rotation axis of the support upright to get close to the coiler, the sleeve is steadily placed between the two bearing steel members inclined oppositely and slides along the two sets of pulleys of the bearing steel members to get close to and be aligned with the coiler mandrel, and the coiler mandrel can be easily sleeved with the sleeve, therefore, the sleeve is mounted on the coiler mandrel safely and efficiently.

Description

technical field [0001] The invention relates to the technical field of continuous stripping, hot-dip galvanizing and color coating equipment of steel plates, in particular to a sleeve installation device for a reel of a coiler. Background technique [0002] In order to improve the product quality requirements in the production of the steel plate continuous unwinding, hot-dip galvanizing, and color-coating production units, paper sleeves or other material sleeves will be put on the coiler reel at the exit of the unit to avoid If the inner circumference of the finished product is coiled with marks, scratches or the finished product collapses, the quick and safe installation of the sleeve is an important factor to ensure the product quality of the continuous unwinding, hot-dip galvanizing and color coating units. [0003] Usually, when the sleeve needs to be added in production, one person is required to carry out the coiling operation on the console, and one person is required...

AI Technical Summary

Problems solved by technology

[0006] (3) The safety risk is high, the exit pit is deep, and the sleeve loading operation needs to stand on the edge of the pit, and the operator has the risk of falling into the pit. If the roll operator does not cooperate properly or makes a mistake, there is a risk that the upper sleeve operator will be crushed by the guide plate

[0007] (4) The operation takes a long time, and the time for putting on the sleeve is too long, which will affect the winding time of the export section, which will easily lead to an excessively high amount of export loops, which has a great hidden danger to the smooth production, and the finished product is defective and needs to be divided into small rolls due to export If the amount of loops is too high, the defective parts cannot be divided into rolls in time, resulting in an increase in the quantity of unqualified products

[0008] (5) The labor intensity is high. The weight of a 15mm thick paper sleeve is about 15 kg, the weight of a 20mm thick paper sleeve is about 25 kg, and the sleeve of other materials can reach 45 kg. The normal production of a shift takes about 20 The upper sleeve operation is about once, and the labor intensity of frequent operations is huge, time-consuming, labor-intensive, and the operation risk is high
