Automatic control device of drying roller

Abstract

The invention provides an automatic control device of a drying roller, belongs to the field of surface treatment of sheet material, and particularly relates to an automatic control device in the field of surface treatment of discontinuous strip material. The automatic control device of the drying roller includes a pinch roll 1, a drying roll 2, a detection member 4 and an execution member 5, and the detection member 4 is mounted between the pinch roll 1 and the drying roll 2. The pinch roll 1 includes a first pinch roll and a second pinch roll, and the first pinch roll is an inlet of strip material. The drying roll 2 is composed of an upper roll and a lower roll, the lower roll is fixedly mounted on a pedestal, and the upper roll is mounted on a support; and the upper roll of the drying roll 2 can be uplifted along with the support. By adopting an automatic control for pressing down, an end of strip steel can be prevented from directly impacting the drying roll 2, abrasion is effectively reduced, the service life of the drying roll 2 can be extended, the manufacturing cost can be reduced, the frequency of changing rolls is reduced, and the production efficiency is raised.

Description

technical field [0001] The invention belongs to the field of plate surface treatment, in particular to an automatic control device in the field of discontinuous plate and strip surface treatment. Background technique [0002] In the production process of the existing cleaning treatment line figure 1 In the process, there will be cleaning liquid residue on the surface of the strip after the cleaning process section. The existing production line mainly adopts the method of squeezing the dry roller to remove the residual cleaning liquid on the surface of the strip. In the prior art, every time the strip passes through the cleaning process section, the strip head will impact the wringing roll surface, and the wringing roll surface is made of acid-resistant rubber, and the impact of the strip head will inevitably be on the roll surface. Impact marks are left and wear on the squeeze roller, especially when cleaning and processing 4mm thick strips, the wear on the squeeze roller i...

Problems solved by technology

[0003] In order to overcome the serious wear and tear problem of the squeeze rollers in the existing cleaning treatment production line, the present invention provides an automatic control device for the squeeze rollers in the cleaning treatment line, by adding a detection element behind the pinch rollers to calculate the length of the strip passing through, And cooperate with the executive element to realize the automatic control of the lifting and pressing of the squeezing roller, avoiding the impact of the head on the roller surface, and prolonging the service life of the squeezing roller
