1. can withdraw out the screw feeding rod after accomplishing extrusion work through the drive assembly who sets up, and then make things convenient for the raw materials of staff's clearance screw feeding rod on and the raw materials in the conveyer pipe, and then when guaranteeing to carry out the extrusion of another kind of plastics next time, off-the-shelf performance after next extrusion can not be influenced to these remaining raw materialss, the drive assembly specific use is: after extrusion work is completed, the handle is twisted anticlockwise, the screw is driven to rotate, due to the fact that a thread through hole is connected with the screw in a threaded mode, under the limiting effect of a metal optical axis, the T-shaped sliding seat retreats backwards in a T-shaped groove, and then the movable plate, the right-angle plate and the motor retreat, the connecting shaft retreats along with the screw feeding rod until the screw feeding rod retreats to be separated from the conveying pipe, at the moment, a worker can clean raw materials on the screw feeding rod and raw materials in the conveying pipe, after cleaning is completed, the handle is twisted clockwise, the screw feeding rod is driven to push the conveying pipe into the conveying pipe until the bearing is clamped into the fixing plate, the bearing is matched with the sealing seat to plug one end, used for withdrawing the screw feeding rod, of the conveying pipe, raw material leakage is avoided, subsequently, magnetism is generated when an electromagnet sleeve is electrified, the metal optical axis is firmly adsorbed and fixed by the electromagnet sleeve at the moment, the T-shaped sliding seat is further fixed in the T-shaped sliding seat, and the bad consequence that the raw materials are leaked due to the backward movement of the screw feeding rod during extrusion work is avoided.

2. The T-shaped sliding seat is provided with the transverse idler wheels, the movable plate is provided with the vertical idler wheels, in the process that the T-shaped sliding seat and the movable plate move back and forth, the transverse idler wheels are arranged to reduce the friction resistance between the T-shaped sliding seat and the inner wall of the T-shaped groove, and the vertical idler wheels reduce the friction resistance between the movable plate and the top end face of the workbench.

3. Through the oil feeding mechanism who sets up, when needs oil feeding, the staff pours into lubricating oil through leading the oilhole, lubricating oil gets into the oil groove from leading the oilhole, rethread toper through-hole gets into in the screw thread through-hole, and then realize the effect of lubricated screw thread through-hole and lead screw, and the oil groove is as the transfer station of lubricating oil, can hold more air, therefore, get into the oil groove at lubricating oil after, atmospheric pressure can crowd lubricating oil into the toper through-hole fast and accomplish oil feeding, and traditional oil feeding mode is only a single chamber way and carries out oil feeding, this kind of chamber way short distance is still good, in case will lead to lubricating oil to advance resistance increase oil feeding speed suddenly drop a little long point apart from easily, and the oil feeding mechanism of this application just does not have this kind of defect, can send lubricating oil to lubricated department fast, in addition, the setting up of toper through-hole guarantees to get into lubricating oil wherein not only can flow out smoothly and can also avoid once flowing out too much, because, lubricating oil top in the toper through-hole is great with atmosphere crimping contact surface, promote lubricating oil slowly from toper through-hole bottom outflow.

4. Because the opening at the upper end of the T-shaped groove is exposed, some sundries can fall into the T-shaped groove, the sundries fall into the cleaning groove from the T-shaped groove under the self gravity, the connecting rod moves along with the T-shaped sliding seat in the process of moving back and forth, the cleaning block is further driven to move back and forth, and when the spiral feeding rod is withdrawn, the cleaning block retreats to push the sundries on the end face of the bottom of the cleaning groove to the dust outlet, so that the cleaning work is completed.

5. In the process of withdrawing from or sending into the screw feeder pole, the limiting plate can produce relative displacement with horizontal optical axis, and the limiting plate holds the connecting axle and restricts the trend of connecting axle through wear-resisting sleeve, guarantees the stability that the screw feeder pole removed, and the half slot on the right angle board can play certain support and limiting displacement to horizontal optical axis, and wear-resisting telescopic setting can reduce the friction loss of connecting axle.

6. Because drive assembly can withdraw out the spiral feed rod after accomplishing extrusion work, consequently, the staff just inspects the state of spiral feed rod, in time changes or maintains it after the damage appears in the helical tooth of discovery spiral feed rod, has effectively improved the maintenance effect of spiral feed rod.
