Oil removing device and oil removing method for aluminum plate base for CTP production

Abstract

The invention discloses an oil removing device for an aluminum plate base for CTP production. The oil removing device comprises an oil removing box, a mounting plate, a cleaning mechanism and a wiping mechanism; the wiping mechanism is arranged on the mounting plate; the wiping mechanism comprises air cylinders, sliding plates, sliding rails, a center plate, movable shafts and wiping rollers, the air cylinders are arranged on the top face of the mounting plate, the two sliding plates are arranged in parallel and located between the two sliding plates, and the output ends of the air cylinders are connected with one sliding plate; the center plate is rotatably mounted in the middle of the mounting plate, the two ends of the center plate are respectively connected with the movable shafts, and the ends, away from the center plate, of the movable shafts are connected with sliding plates; and the cleaning mechanism comprises water inlet pipes, flow dividing pipes, spraying plates and spraying holes, the water outlet ends of the water inlet pipes communicate with the middles of the flow dividing pipes, the flow dividing pipes communicate with the multiple sets of spraying plates, and the multiple sets of spraying holes are evenly formed in the side walls, away from the oil removing box, of the spraying plates. According to the oil removing device, an aluminum plate can be thoroughly subjected to oil removing work, and the working efficiency of oil removing for the aluminum plate is improved.

Description

technical field [0001] The invention belongs to the technical field of CTP plates, in particular to a degreasing device and a degreasing method for an aluminum plate base used in CTP plate production. Background technique [0002] The CTP plate and the PS plate are coated with a photosensitive layer on the surface of the aluminum plate base. In order to make the aluminum plate base have a good adsorption effect on the photosensitive layer, the surface of the aluminum plate base must undergo a series of surface treatments: degreasing→neutralization→electrolysis→oxidation→sealing and other processes. [0003] Chinese patent CN103215604B discloses a degreasing method for an aluminum plate base used in CTP plate production, and the method is used for degreasing the surface of an aluminum plate base in CTP plate production. This method makes full use of the advantages of the soaking method and the spraying method. The front of the aluminum plate base adopts the spraying method, ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem in the prior art that CTP plate manufacturers have abandoned the soaking method and changed it to the spraying method in the degreasing process. Swelling of the plate belt causes scratches or tension fluctuations; the spraying method can achieve the purpose of sufficient corrosion on the front side and mild corrosion on the back side through more nozzles on the front side and fewer nozzles on the back side; and the equipment used in this degreasing method is often directly used The two groups of nozzles can be sprayed, but there is a problem that the degreasing is not thorough and comprehensive enough. It is only a simple cleaning of the surface of the aluminum plate, and a degreasing device and an aluminum plate base for CTP plate production are proposed. degreasing method
