Waste edge coiler and its width adjustment device

Abstract

The invention discloses a width adjustment device of a coiler for trimmings. The width adjustment device of the coiler for trimmings comprises a bidirectional threaded rotary element, a driving mechanism, a left support and a right support, wherein the driving mechanism is used for driving the bidirectional threaded rotary element to rotate; the left support and the right support are both fixedly installed on a bracket of the coiler for trimmings; the left support is internally provided with a left installation through hole which is internally provided with a left coiling block support shaft matched with the unidirection of the left installation through hole in a sliding mode; the end surface of the left coiling block support shaft is provided with a left threaded hole; the right support is internally provided with a right installation through hole which is internally provided with a right coiling block support shaft matched with the unidirection in a sliding mode, and a right threaded hole is formed in the end surface of the right coiling block support shaft; the threaded turning directions of the left threaded hole and the right threaded hole are opposite; two ends of the bidirectional threaded rotary element are respectively provided with a left screw matched with the left threaded hole and a right screw matched with the right threaded hole; and the bidirectional threaded rotary element is provided with a drive element matched with the driving mechanism. The invention also discloses a coiler for trimmings of the width adjustment device.

Description

technical field [0001] The invention belongs to the technical field of waste edge coiling cut by disc shears after strip steel pickling, and particularly relates to a waste edge coiler and a width adjustment device thereof. Background technique [0002] In the cold rolling production line, the edge of the pickled steel plate needs to be cut by disc shears to meet the width requirements of the finished strip. At present, there are two main ways to deal with the waste edges cut by the disc shears: one is to directly chop the waste edges, and then return the chopped waste edges to the furnace; the other is to roll the waste edges into regular Steel coils, as raw materials for the hardware and metal products industries, can be sold as finished steel coils. From the utilization benefits of the waste edges treated in the two ways, it is not difficult to see that the waste edge coiling has very high economic value. Therefore, the waste edge coilers are widely used. [0003] The c...

Problems solved by technology

[0003] The coiling device of the existing waste edge coiler is a fixed structure, the distance between the two reels is fixed, and the width of the incoming strip steel by the disc shears is different, which leads to In the actual coiling process of the coiling device, when the width of the incoming strip steel exceeds the distance between the two drums of the coiling device, the drum of the waste edge coiler cannot coil the waste edge within the full length. , when the distance is too large, there will be only 2 / 3 of the reel, or even less than 1 / 2 part can effectively take up the waste edge

This will lead to a great reduction in the effective amount of waste edge coiled by each roll, increasing the frequency of unloading rolls, which greatly affects the production rhythm and production efficiency

[0004] The Chinese patent whose publication number is CN 101181725 discloses a kind of waste edge coiling machine, although this waste edge coiling machine can meet the requirements of waste edge coiling to a certain extent, but the gap between its left reel and right reel The distance still adopts a non-adjustable fixed structure, resulting in that when the width of the incoming strip steel exceeds the distance between the two reels, the reel cannot achieve full-length coiling
