Coating machine

Abstract

The invention discloses a coating machine which comprises a machine frame and a rotary arm mechanism arranged on the machine frame, wherein the rotary arm mechanism comprises a main rotary arm and a main air cylinder, the main rotary arm is arranged on the machine frame, the main air cylinder is used for driving the main rotary arm; one end of the main rotary arm is articulated with a piston rod of the main air cylinder; the rotary arm mechanism also comprises a locking mechanism for fixing the main rotary arm; the main rotary arm is provided with a locking shaft near to the articulating end; the locking shaft is matched with the locking mechanism; the locking mechanism comprises a locking rotary arm and a locking air cylinder, wherein the locking rotary arm is rotatably arranged on the machine frame, the locking air cylinder is used for driving the locking rotary arm; one end of the locking rotary arm is articulated with the piston rod of the locking air cylinder; the other end of the locking rotary arm is provided with a cam block which is used for blocking the locking shaft at a rotating direction of the main rotary arm; and the cam block is provided with a locking concave surface which is used for being matched with and locked with the locking shaft. The coating machine does not give rise to the clearance change due to the sloshing of the main rotary arm and reduces the influence of the rotary arm mechanism to the sizing agent and coating weight when the rotary arm mechanism is used for coating textiles.

AI Technical Summary

Problems solved by technology

The fixation of the rotating arm is controlled by the piston rod of the cylinder, but relying on the piston rod of the cylinder cannot completely ensure that the rotating arm does not move. Therefore, the instability of the rotating arm will cause the change of the gap between the coating knife and the support roller, which affects the thickness of the coated slurry. and influence the control of coating amount
