[0007] As a further optimization of the present invention, the plate body is fixedly connected to the rotating shaft through a connecting hole, two positioning holes are opened inside the plate body, and the two positioning holes are arranged at the upper and lower ends of the plate body. The plate body is slidingly connected to the reset plate and the piston plate respectively through the positioning holes.
[0008] As a further optimized content of the present invention, wherein: the movable column is slidably connected inside the fixed column, one end of the movable column is fixedly connected to the first spring, and the other end of the movable column is fixedly connected to the bottom of the storage hole.
[0009] As a further optimization of the present invention, there are two control mechanisms and two storage holes, and the control mechanisms and the storage holes correspond one to one.

[0013] As a further optimized content of the present invention, the following steps are included: Step I: water-grinding the polytetrafluoroethylene waste: pouring the polytetrafluoroethylene waste into a waste water mill, grinding it for reuse; Step II: The treated polytetrafluoroethylene powder flows into one side of the collection bin through the discharge port together with water: the polytetrafluoroethylene residue is processed by the residue water mill to become polytetrafluoroethylene powder, and is discharged into the collection bin together with water; Step III: The cleaning mechanism transfers the polytetrafluoroethylene powder from one side to the other side: During the operation of the device as a whole, every 10 minutes, the stepper motor drives the shaft to rotate at a specific angle. During the rotation of the shaft, the fixed shell is driven to rotate. During the rotation of the fixed shell, the sieve plate is driven to rotate. During the rotation of the sieve plate, the polytetrafluoroethylene powder is transferred to the other side of the collection bin and water is controlled during the rotation. When the sieve plate completely enters the other side of the collection bin, the reset plate contacts the top block and is squeezed.

When the piston plate contacts the partition, the piston plate moves toward the horizontal plate, so that the card block is connected to the vertical card plate, and at the same time, the gas between the connecting plates is pushed into the fixed column, so that the sieve plate is moved out of the plate body and obliquely inserted into the collection bin. Step IV: Collect the polytetrafluoroethylene powder transferred to the other side of the collection bin and proceed to the next process: After the polytetrafluoroethylene powder enters the end of the collection bin away from the discharge port, the staff takes it out for drying.
[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the stepper motor and the cleaning mechanism are arranged, and the original collecting box is transformed. The rotation of the cleaning mechanism can remove a large amount of moisture from the powder material coming out of the water mill discharge port and place it separately. No manual input is required, the efficiency is high, and the transformation cost is relatively low. It is suitable for small processing plants; 2. In the present invention, the position of the sieve plate can be automatically adjusted according to the rotation angle of the stepper motor. When entering the side of the collecting shell away from the discharge port, the sieve plate is completely stored inside the plate body, and the powder on the upper end of the sieve plate can be unloaded. When entering the side of the collecting shell close to the discharge port, the powder can be obliquely inserted into the collecting bin to avoid the problem that more powder is at the lower end of the sieve plate and cannot be transferred to the other side of the collecting bin. 3. In the present invention, the air supply mechanism is automatically adjusted through the position of the plate body, and no electronic equipment and control system are required. The screen plate contraction control can be achieved, the production cost is low, and the service life is short, and it is more suitable for working in a humid environment.

During the rotation of the sieve plate (42), the polytetrafluoroethylene powder is transferred to the other side of the collecting bin (3) and water is controlled during the rotation. When the sieve plate (42) completely enters the other side of the collecting bin (3), the reset plate (444) contacts the top block (33), the reset plate (444) is squeezed, and during the squeezing of the reset plate (444), the reset plate (444) is driven The horizontal plate (449) moves. During the movement of the horizontal plate (449), one end of the through hole (4410) enters the interior of the sealing shell (441), thereby discharging the gas inside the sealing shell (441). At this time, the movable column (432) moves toward the interior of the fixed column (431), and drives the sieve plate (42) to move toward the interior of the plate body (411), thereby pouring the polytetrafluoroethylene powder on the sieve plate (42) into the inner side of the end of the collecting bin (3) away from the discharge port (2). During this process, the cylinders at both ends of the horizontal plate (449) push the semicircular block (448) to move to one side, thereby separating the clamping block (446) from the vertical clamping plate (447). After the clamping block (446) and the vertical clamping plate (447) are separated, the piston plate (443) automatically resets. Then, the stepper motor (5) is reset, and when the piston plate (443) fails to contact the top block (33) on the other side of the partition plate (32), the sieve plate (42) is located inside the plate body (411). When the piston plate (443) contacts the partition plate (32), the piston plate (443) moves toward the horizontal plate (449), so that the clamping block (446) is connected to the vertical clamping plate (447), and at the same time, the gas between the connecting plates (445) is pushed into the fixed column (431), thereby moving the sieve plate (42) out of the plate body (411) and obliquely inserting it into the collection bin (3); Step IV: The polytetrafluoroethylene powder transferred to the other side of the collecting bin (3) is collected and entered into the next process: After the polytetrafluoroethylene powder enters the end of the collecting bin (3) away from the discharge port (2), the staff takes it out for drying.
