[0005] 2. Due to reasons such as processing and wear, there will be a certain gap between the gears, resulting in a decrease in accuracy and affecting the reliability and stability of the transmission.

[0006] 3. During the gear transmission process, friction generates heat, causing the system temperature to rise, accelerating wear and aging.

[0007] 4. The reducer is an open-loop control method. Due to the lack of feedback control signal, its control accuracy has certain limitations, which has a certain impact on the positioning accuracy.

[0028] The spring 23 is a conical tower spring, which can minimize the diameter of the top limit platform of the support rod 24, thereby reducing the fluidity of the falling material.

[0029] The driving rotating device includes a servo motor 1, a transmission shaft 2, a motor connecting seat 3 and a sealing seat 4; the top of the connecting disk 6 is connected to the base of the servo motor 1 through the sealing seat 4 and the motor connecting seat 3 in turn, the output shaft of the servo motor 1 is connected to the rotating disk 7 through the transmission shaft 2, a deep groove ball bearing 15 is provided at the upper end of the inner cavity of the sealing seat 4, the deep groove ball bearing 15 is coaxially supported between the transmission shaft 2 and the sealing seat 4, and two sealing rings 16 are provided at the lower end of the inner cavity of the sealing seat 4, and the sealing ring 16 is rotationally sealed with the transmission shaft 2.

This control method can accurately control the parameters such as the position, speed and acceleration of the servo motor.

[0032] In this embodiment, the injection cylinder 12 is required to drive the discharge shaft 13 to move downward. When the trigger rod 26 is pushed upward by the limit rod 18, a gap is generated between the wedge-shaped annular discharge port between the blocking block 22 and the sealing cover 21, and the material can flow out from the gap.

[0033] The specific working process of the above two embodiments is as follows: when a certain workstation needs to inject material, the servo motor 1 is controlled to rotate through an external control mechanism. When the corresponding feed connector 8 reaches directly below the designated injection device 10, the injection cylinder 12 is started, and the feed shaft 13 moves downward to drive the injection nozzle to move downward as a whole. When the bottom surface of the sealing cover 21 contacts the rotating disk 7, the feed shaft 13 starts to inject material, and the material enters the designated workstation through the feed connector 8 and the hose 9 to complete the injection.
