Device and method for controlling distance between paint on silicon steel sheet

Abstract

The invention discloses a separation distance control device and method for silicon steel sheet feeding for painting. The separation distance control device and method for silicon steel sheet feedingfor painting comprises a mechanical execution system and an electronic control system. The mechanical execution system comprises a body, a gas cylinder part, a positioning block and a supporting block. The positioning block and the gas cylinder part are fixed to the body. The gas cylinder part is provided with an inclined piston rod with a certain angle away from the horizontal surface. The supporting block is connected to the piston rod. The positioning block is used for positioning a stamping sheet. The supporting block is used for supporting the stamping sheet. The electronic control systemis connected with the gas cylinder part and controls the piston rod of the gas cylinder part to stretch out and draw back within the set time, so that the supporting block moves back and forth between the position of stretching out and the position of drawing back. The position of stretching out is the position where the lower surface of the supporting block making contact with a conveyer belt for silicon steel sheets. The position of drawing back is the position, away from the conveyer belt for the silicon steel sheets, of the supporting block. The separation distance control device can haveaccurate control over the separation distance between two adjacent silicon steel sheets which are fed, the operation is easy and convenient, and a very good effect is achieved on improving and keeping the painting quality of stamping sheets.

Description

technical field [0001] The invention relates to equipment automation, in particular to a device and method for controlling the spacing between paint on silicon steel sheets. Background technique [0002] Due to environmental protection reasons, the paint coating of motor punches is gradually changing from organic solvents to water solvents, but the process requirements for water-soluble paints are relatively strict. When using existing equipment, if the distance between the two punches is too close, the previous one The marks left by one punch on the paint roller will be printed on the next punch, causing water marks on the surface of the punch to reduce the apparent quality, and in severe cases, it will affect the uniform distribution of paint film thickness. According to the process requirements, the paint roller must be rolled in an empty circle to make the thickness of the paint film consistent. However, when the film is loaded by hand, the film is always in motion, and ...

[0002] Due to environmental protection reasons, the paint coating of motor punches is gradually changing from organic solvents to water solvents, but the process requirements for water-soluble paints are relatively strict. When using existing equipment, if the distance between the two punches is too close, the previous one The traces left by one punch on the paint roller will be printed on the next punch, resulting in water marks on the surface of the punch, reducing the apparent quality, and even affecting the uniform distribution of paint film thickness in severe cases

According to the process requirements, the paint roller must be rolled in an empty circle to make the thickness of the paint film consistent. However, when the film is loaded by hand, the film is always in motion, and there is no good reference for reference. The production schedule will also artificially shorten the distance between punching sheets, resulting in batch problems for products
