[0029] Working principle of a plunger spray clamping device:
[0030] When the plunger needs to be sprayed, first, one end of the plunger is attached to the arc-shaped clamping plate 2 fixed at the bottom of the side of the fixed plate 16, and then the motor 3 20 is started. The motor 3 20 rotates, driving the screw 3 18 to rotate, thereby driving the sliding plate 2 17 to slide close to the fixed plate 16, and the arc-shaped clamping plate 2 below the sliding sliding plate fits and supports the bottom of the other end of the plunger, which is suitable for clamping and spraying plungers of different lengths, and the scope of application is expanded.
[0031] When the plunger is clamped and stabilized, the short rod 9 on the telescopic rod 7 is then pressed to separate the positioning block 10 from the positioning hole 8, and then the outer rod 72 is pulled to slide on the inner rod 71. The position of the outer rod 72 on the inner rod 71 is adjusted according to the distance between the nozzle 6 and the plunger. After the distance between the nozzle 6 and the plunger is determined, the external force is released, and the spring drives the short rod 9 to rotate, so that the positioning block 10 is clamped into the positioning hole 8 again. The nozzle 6 and the plunger maintain a suitable distance, which is conducive to more uniform spraying.
[0032] Finally, start the motor three 20 in the supporting vertical plate 5 to drive the double-headed screw 3 to rotate, so that the two arc-shaped clamping plates 2 in each clamping assembly are close to each other to clamp the plunger, and then start the motor one 24, and the motor one drives the active synchronous pulley to rotate. Since the active synchronous pulley is connected to the driven synchronous pulley two through the limit rod 22, it can simultaneously drive the supporting vertical plates 5 in the two clamping assemblies to rotate in the fixed plate 16 and the sliding plate. At the same time, start the motor two 15 to drive the spray head 6 to slide along the length direction of the plunger. While the plunger rotates, the spray head 6 sprays it, so as to efficiently complete the coating of the plunger and automatically spray, saving time and effort and significantly improving work efficiency.
