[0032] In this embodiment, preferably, a receiving plate 59 is fixedly connected to one side of the metering cylinder 5, and a rotating rod 510 is rotatably provided on the bottom wall of the receiving plate 59.

[0036] The working principle and use process of this utility model:

[0037] In actual application, the operator needs to firstly turn the screw 53 according to the required amount of plastic particles. The screw 53 drives the adjusting plate 55 to move up and down along the inside of the quantitative cylinder 5 by cooperating with the nut 52, so as to adjust the space of the quantitative cylinder 5 to accommodate the plastic particles. When the adjusting plate 55 moves, it drives the adjusting tube 62 to slide along the outer wall of the fixed tube 61, which can effectively control the amount of plastic particles entering the quantitative cylinder 5, and ensure that the feeding position is adjustable and the level of the adjusting plate 55 is maintained, so as to ensure that the plastic particles can completely fill the space of the quantitative cylinder 5 to accommodate the plastic particles, and ensure the accuracy of quantitative measurement.

[0038] Then, different plastic particles are put into the storage barrel 4, and the electric push rod B8 drives the blocking plate 81 to block the discharge position of the quantitative barrel 5, and then the electric push rod A7 drives the frame 71 to move the blocking piece 72 to connect the fixed pipe 61, and the plastic particles in the storage barrel 4 can pass through the fixed pipe 61 and the regulating pipe 62 in turn to enter the quantitative barrel 5, until the plastic particles fill the space for accommodating the plastic particles in the quantitative barrel 5, so that the blocking piece 72 blocks the fixed pipe 61, and the quantitative amount of the plastic particles is achieved, and then the blocking plate 81 is opened, and the plastic particles can fall into the discharge hopper 2 to achieve quantitative discharge;

[0039] In the above process, the motor 56 can drive the rotating shaft 57 to rotate, and the rotating shaft 57 drives the anti-blocking rod 58 to prevent blockage at the discharge position of the metering cylinder 5. At the same time, the rotating shaft 57 can drive the active sprocket 514 to rotate. The active sprocket 514 drives the driven sprocket 515 to rotate through the transmission of the chain 516, thereby driving the worm 512 to rotate. When the worm 512 rotates, it engages with the worm wheel 513, and then the worm wheel 513 drives the rotating rod 510 to rotate. The rotating rod 510 can drive the anti-blocking strip 511 to rotate and stir the plastic particles in the adjusting tube 62 and the fixed tube 61, thereby avoiding blockage.
