Roll coater for multilayer board blank

Abstract

The invention discloses a roll coater for a multilayer board blank, which comprises an upper roller and a lower roller of the roll coater. The bearing seats of roll shafts on two ends of the upper roller and the lower roller are connected with a frame, wherein, the bearing seat of the roll shaft of the upper roller can move up and down along the frame when a connecting bolt of the bearing seat is loosened. The roll coater is characterized in that a bracket is arranged below the bearing seat of the roll shaft of the upper roller. In the invention, the bracket is arranged below the bearing seat of the upper roller of the roll coater connected with the frame, so the upper roller is tightened by the bolt and supported by the bracket after a roll gap is well-adjusted. Therefore, the upper roller can not move downwards.

Description

technical field [0001] The invention relates to sheet metal processing equipment, in particular to a glue rolling machine for the slab gluing process in the production process of multilayer boards. Background technique [0002] In the production process of multi-layer boards, the slabs must be glued with a rubber roller, and then the slabs are stacked together and hot-pressed. At present, the rubber rolling machine used generally adopts the method of rolling up and down rollers, and the thickness of the slab to be glued is inconsistent, and the roll gap often needs to be adjusted. At present, the installation method of the rollers and the frame is: The roller bearing seat of the roller is fixedly connected to the frame, and the roller bearing seat of the upper roller is slidingly connected with the frame, that is, there is a hole on the frame. Penetrate into the frame hole to push the bearing seat to the top, but during the production process, the roller often moves down, r...

At present, the installation method of the rollers and the frame is: The roller bearing seat of the roller is fixedly connected to the frame, and the roller bearing seat of the upper roller is slidingly connected with the frame, that is, there is a hole on the frame. Penetrate into the frame hole to push the bearing seat to the top, but during the production process, the rollers often move down, resulting in the roll gap being too small to meet the production requirements
