[0002] The powder spraying system is widely used in industrial production. The spray guns of the powder spraying system are usually installed horizontally according to the shape of the workpiece, and then a lifting device is used to drive the horizontally set spray gun group to move up and down to realize the spraying of large workpieces. Spraying, the lifting device is usually driven by hydraulic pressure or motor. When using motor drive, it usually uses sprocket drive, screw drive, etc. In this type of drive mode, the motor often needs to switch between forward and reverse to realize the spray gun Move up and down, but the motor often switches between forward and reverse, which will reduce the service life of the motor, and even burn the motor

The invention discloses a pulley structure swinger with an extension spring. The pulley structure swinger with the extension spring comprises a base, a driving motor which is installed on the base, a spray gun rack which is arranged on the base through a pulley device, a connecting rod mechanism which is connected with the driving motor and the spray gun rack, and a spring device which takes a buffering effect. The connecting rod mechanism and the pulley device form a crank and sliding block mechanism. The driving motor can drive the spray gun rack to move up and down through the crank and sliding block mechanism. In the entire spray-coating process, the driving motor is only required to rotate always towards one direction, so that the service life of the driving motor is prolonged. Moreover, since the spring device is configured and is used for taking the buffering effect when the spray gun rack moves to a limit position at the upper end or the lower end, the impact to the driving motor at the limit position is reduced and the service life of the driving motor is further prolonged.
Description
technical field [0001] The invention relates to a swinger with tension spring pulley structure which is applied to the lifting and lowering of a spray gun in a powder spraying system. Background technique [0002] The powder spraying system is widely used in industrial production. The spray guns of the powder spraying system are usually installed horizontally according to the shape of the workpiece, and then a lifting device is used to drive the horizontally set spray gun group to move up and down to realize the spraying of large workpieces. Spraying, the lifting device is usually driven by hydraulic pressure or motor. When the motor is used, it is usually driven by a sprocket or a screw. Moving up and down, however, frequent forward and reverse switching of the motor will reduce the service life of the motor, and even burn the motor. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a swinger with te...
