Pneumatic motor with dead-point-free exhaust reversing mechanism

Abstract

The invention discloses a pneumatic motor with a dead-point-free exhaust reversing mechanism. An air cylinder, a piston and the dead-point-free exhaust reversing mechanism are included. The piston islocated in the air cylinder and divides the air cylinder into an upper cavity, a lower cavity and a dead point preventer arranged at one end of the reversing piston. The dead-point-free exhaust reversing mechanism is used for switching an air inlet channel and an air outlet channel of the air cylinder. According to the disclosed pneumatic motor with the dead-point-free exhaust reversing mechanism,through additional arrangement of the reversing mechanism with the reasonable structure, the reversing capability of the pneumatic motor is improved, impacts are effectively reduced in the forward rotation and reverse rotation process, load unloading is not needed, the cruising time of the pneumatic motor is prolonged, and noise is effectively lowered through additional arrangement of an exhaustsilencer; and an anti-freezing air distribution block is additionally arranged, air outlet way freezing during rapid exhausting is effectively prevented, and reversing reliability is greatly improved.

Description

technical field [0001] The invention relates to the field of pneumatic spraying equipment, in particular to an air motor with a non-dead point exhaust reversing mechanism. Background technique [0002] As an indispensable power source in spraying equipment, the air motor for spraying is widely used in spraying production. In order to realize the forward rotation and reverse rotation of the output shaft of the air motor, and to change the direction instantaneously, when the forward and reverse conversion is performed, the impact force Small, the engineers worked tirelessly. The main advantage of the reversing work of the air motor is that it has the ability to rise to full speed almost instantaneously. It uses the operating mechanism to change the intake direction to achieve positive and negative rotation. The advantage of needing to unload the load. [0003] The existing operating mechanism used to change the air intake direction of the air motor has complex structure, low...

AI Technical Summary

Problems solved by technology

[0003] The existing operating mechanism used to change the air intake direction of the air motor has complex structure, low precision, high noise, easy to freeze, poor exhaust and easy to produce dead spots, short battery life, and poor reliability, especially in forward and reverse conversion. It is very easy to produce a stuck position when turning, resulting in unsuccessful commutation of the air motor
