Opening and closing mechanism for esters coating valve

Abstract

The invention discloses an opening and closing mechanism for an esters coating valve. The opening and closing mechanism comprises a mounting plate and a floating coupling; a motor is arranged on the mounting plate; one end of the floating coupling is connected with a mainshaft of the motor, and a firing pin connecting piece is fixed on the other end of the floating coupling; the mainshaft of the motor is a screw rod on which the screw rod can move; a firing pin is fixed on the firing pin connecting piece; the rotating speed, the number of turns, the forward and reverse rotation directions and the forward and reverse rotation switching time of the motor are controlled by a controller. When the opening and closing mechanism works, the controller is set first, then the motor is started, and the mainshaft of the motor rotates forwards or reversely to drive the floating coupling to move forwards or backwards, so that the firing pin finishes a task of closing or opening a high-viscosity coating valve. The opening and closing mechanism for the esters coating valve is stable to work without impact, fast in response, high in precision, low in fault rate and widely applied, and the working state of the opening and closing mechanism can be controlled in a digitalized manner.

Description

technical field [0001] The present invention relates to a switch mechanism for an ester coating valve. Background technique [0002] What the high-viscosity coating valve in the prior art adopts is a pneumatic switch mechanism, such as figure 1 As shown, it includes: cylinder 1, cylinder 1 is provided with cylinder connector 2 and adjustment screw 3, and cylinder connector 2 is provided with striker 4; adjustment screw 3 can adjust the stroke of cylinder rod, thereby driving striker 4 to coat The cloth valve is sealed or opened, and the stroke of the cylinder rod is adjusted properly and then fixed with the lock nut 5; [0003] Its disadvantages are: the pressure of air source, the temperature and humidity of the environment, and the vibration generated during work will all cause the instability of the working state of the coating valve; the vibration of the cylinder and the connecting rod of the cylinder will cause the striker to appear eccentric, resulting in The stop se...
