Description

Technical Field

[0001] The invention relates to the field of feeding for pipe fitting processing, in particular to a feeding device and a feeding method for polyethylene (PE) pipe fitting processing. Background Art

[0002] PE pipe fittings refer to pipe connectors made of polyethylene materials. PE pipe fittings are of high quality and low price. They have locking hoops, stepped annular sealing rings and other components inside. They are scientifically designed, strong and have good sealing properties. When processing polyethylene PE pipe fittings, they need to be moved by conveyor belts.

[0003] Generally, the pipe is pushed from one side of the conveyor belt to the placement plate on the conveyor belt, and the placement plate drives the pipe to move through the operation of the conveyor belt. However, since the pipe is a cylindrical structure, when the conveyor belt drives the pipe to move for feeding, the pipe is prone to rolling, which will affect the conveying effect of the conveyor belt on the pipe. It will also cause friction between the pipe and the placement plate, causing wear of the pipe. When the pipe is placed on the placement plate, the gravity of the pipe will directly act on the conveyor belt. Long-term use will easily cause deformation of the conveyor belt, thereby affecting the transportation and feeding of the pipe. Summary of the invention

When the supporting plate drives the pipe fitting to move, the guide wheel is squeezed by the guide connecting plate and the guide sleeve block, so that the push plate moves upward. At the same time, the first piston rod drives the side connecting plate to move toward the pipe fitting. In this way, the pipe fitting on the supporting plate can be limited by the movement of the push plate and the side connecting plate to prevent it from slipping due to bumps or the movement of the conveyor belt during the loading process, so as to maintain the stability of the pipe fitting at the predetermined position and prevent the pipe fitting from being worn during the loading process. 2. By setting the support guide, when the mounting block moves with the conveyor belt, the T-shaped support block will move along the gap between the inner guide ring and the outer guide ring. At this time, the inner guide ring and the outer guide ring will support the T-shaped support block. At this time, the gravity of the support plate, the mounting block and other components will act on the T-shaped support block. At the same time, the buckle plate will guide the T-shaped support block to prevent the T-shaped support block from shifting relative to the inner guide ring and the outer guide ring. In this way, the weight borne by the conveyor belt can be reduced, and the accuracy of the conveyor belt in feeding and transporting components can be further improved.

In this way, the moving distance of the side connecting plate 12 and the pushing plate 19 can be adjusted according to the diameter of the pipe. When the support plate 11 drives the pipe to move, the guide wheel 23 is squeezed by the guide connecting plate 21 and the guide sleeve block 20.
