Problems solved by technology

[0004] This structure has been found to have many disadvantages in long-term use: First, it is difficult to adjust the gap between the rollers. The core of the coating machine should be the coating roller. First, ensure the gap between the coating roller and the steel belt, and then other The two rollers adjust the gap between the coating roller and the coating roller based on the coating roller, and this structure adjusts the gap between the coating roller and the coating roller by moving the coating roller up and down. Obviously, the position movement of the coating roller will Break the gap between the coating roller and the steel belt, the coating roller and the metering roller, so that the gaps of the entire system are completely destroyed, and the desired effect must be achieved through repeated adjustments; the second is that it is difficult to replace the coating roller, and the coating roller is easy Damaged parts must be replaced frequently during use. When replacing the coating roller with this structure, the screw rod and its support must be removed. The time is very long, resulting in a large loss of production line shutdown; the third is that the installation accuracy of the coating roller cannot be guaranteed. , because there must be a certain gap between the applicator roller bearing seat and the guide rail to ensure its up and down movement, this gap makes the left and right position of the applicator roller unguaranteed
It also affects the contact between the coating roller and the steel strip, resulting in uneven thickness of the coating film

Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the present invention should not be limited to the embodiments.

[0014] See figure 1 , The present invention is mainly made up of coating roller 11 and its adjustment device, dipping material roller 12 and its adjustment device, metering roller 13 and its adjustment device. The adjustment device of the coating roller 11 is composed of a track 111, a bracket 112, a screw 113, and a nut 114. Through the system of the screw 113 and the nut 114, the entire coating roller group can be moved left and right, and the coating roller 11 is close to the substrate 14. The coating on the surface of the applicator roller 11 can be smoothly and evenly applied to the substrate 14; The nut 124 system can move the dipping roller 12, metering roller 13 and its adjustment device left and right, thereby simultaneously adjusting the gap between the dipping roll...

Abstract

The invention discloses a coating machine of a prepainted steel sheet. The coating machine main consists of a coating roll, a coating roll adjusting device, a coating sticking roll, a coating sticking roll adjusting device, a metering roll and a metering roll adjusting device, wherein, the coating roll and the coating sticking roll are not aligned but staggered in the vertical direction, and the coating roll inclines towards the outside of the coating sticking roll; during adjusting the clearance between the coating roll and a steel belt, the clearance between the coating roll and the coating sticking roll and the clearance between the coating roll and the metering roll are kept unchanged; and during adjusting the clearance between the coating sticking roll and the coating roll, the clearance between the coating roll and the metering roll is kept unchanged. In the invention, a bearing seat used for the coating roll is of a quick disassembly type, i.e., the bearing seat can be opened after a fastening bolt is loosened; and after the original coating roll is replaced with a new coating roll, the fastening bolt is screwed down to completely assemble the coating roll.

Description

technical field [0001] The invention belongs to the technical field of color-coated plate production equipment, and in particular relates to a coating machine for color-coated plate production. Background technique [0002] As is commonly known in the industry, the coating machine for color-coated boards is the main equipment for applying paint to substrates and producing color-coated boards. It generally consists of 2 to 3 rollers, which are dipping rollers, coating rollers and metering rollers Rolls (2-roll coaters omit metering rolls). The role of the dipping roller is to attach the paint of the tray to its surface to be transferred to the applicator roller. The function of the metering roller is to remove excess paint on the surface of the applicator roller, control the effective amount of paint on the surface of the applicator roller, and thereby control the thickness of the coating on the surface of the color-coated plate. The function of the applicator roller is to ...
