A T-shaped support block (15) is provided at one end of the pallet (11) above the push pin (25). The end of the T-shaped support block (15) away from the pallet (11) is located between the inner connecting ring (7) and the outer connecting ring (6). A snap-fit ​​plate (16) connected to the top of the outer connecting ring (6) is provided at the top of the T-shaped support block (15).

7. The feeding device for processing polyethylene (PE) pipe fittings according to claim 6, characterized in that, The distance between the bottom of the end of the fastening plate (16) near the outer guide ring (6) and the inner wall of the outer guide ring (6) is five centimeters.

8. The feeding device for processing polyethylene (PE) pipe fittings according to claim 7, characterized in that, The extrusion plate (22) is located inside the inner guide ring (7), and the vertical central axis of the extrusion plate (22) coincides with the vertical central axis of the inner guide ring (7).

9. A feeding method for processing polyethylene (PE) pipe fittings, characterized in that, The feeding device for processing polyethylene (PE) pipe fittings according to any one of claims 1-8 includes the following steps: S1: The pipe fitting is pushed from above the motor (4) to the top of the pallet (11) by an external pushing device. Then, the operation of the motor (4) causes the conveyor belt (3) to move the mounting block (13), so that the pipe fitting on the pallet (11) moves with the pallet (11). S2: The pipe fittings on the pallet (11) are positioned in multiple directions by correcting the operation of the locking device. At the same time, the weight of the pipe fittings is shared by the support guide device during the movement of the installation block (13) driven by the conveyor belt (3). S3: When the pipe fitting moves from one end of the conveyor body (2) to the other end along with the movement of the pallet (11), the pipe fitting will lose its limit under the operation of the corrective locking device; S4: Remove the pipe fittings for processing.
