Description

Technical Field

[0001] The utility model relates to the technical field of large-diameter PE pipe production, and particularly relates to an anti-sticking backing plate device for multi-specification large-diameter pipes. Background Art

[0002] During the automatic production process of large-diameter PE pipes, they are extruded by a front-end extruder and then cut to a fixed length of 6 meters, 9 meters, and 12 meters by a rear-end cutting machine. The pipes extruded by the extruder push the cut pipes backward. After reaching a certain position, they are flipped to another measurement station for on-line end face size and length measurement operations. Since the pipes produced on-line still have a certain temperature and the front-end pipes push the rear-end pipes backward after cutting, the mutual thrust makes the large-diameter pipes easily stick back at the cutting position. If not separated, it is easy to cause the front-end pipes to be carried over when flipped to the measurement station, resulting in collisions between the continuously extruded and conveyed pipes and the equipment. On the one hand, it damages the pipes, and on the other hand, it also damages the equipment. Since there are three length specifications of pipes, the device also needs to be compatible with the anti-sticking purpose of pipes of three length specifications. Content of the Utility Model

[0045] Please refer to Figure 9 , the device of the present utility model includes an induction pipe turning mechanism. The induction pipe turning mechanism includes a pipe turning induction photoelectric sensor transmitter 12, a pipe turning induction photoelectric sensor receiver 13, a photoelectric sensor receiver fixing bracket 15 and a photoelectric sensor transmitter fixing bracket 16.

[0046] The photoelectric sensor transmitter fixing bracket 16 and the photoelectric sensor receiver fixing bracket 15 are formed by cutting, bending and punching a steel plate. The pipe turning induction photoelectric sensor transmitter 12 and the pipe turning induction photoelectric sensor receiver 13 are used to sense whether the large-diameter pipe 9 is in place, so as to control the pipe turning action. The pipe turning induction photoelectric sensor transmitter 12 and the photoelectric sensor transmitter fixing bracket 16 are connected and fixed by 2 hexagon socket head cap screws. The pipe turning induction photoelectric sensor receiver 13 and the photoelectric sensor receiver fixing bracket 15 are connected and fixed by 2 hexagon socket head cap screws.

[0047] The specific implementation process of the device of the present utility model during production is as follows:

[0048] First, switch the device according to the length specification of the large-diameter pipeline 9 being produced. When producing a pipeline with a length specification of 12 meters, the lifting and abutting cylinders 20 of the 9-meter pipe lifting and abutting mechanism 10 and the 6-meter pipe lifting and abutting mechanism 11 both remain in the contracted state.

[0049] When producing a large-diameter pipeline with a 9-meter specification, the lifting and abutting cylinder 20 of the 9-meter lifting and abutting mechanism 10 extends, and the lifting and abutting cylinder 20 of the 6-meter lifting and abutting mechanism 11 remains in the contracted state.

[0050] When producing a large-diameter pipeline with a 6-meter specification, the lifting and abutting cylinder 20 of the 9-meter lifting and abutting mechanism 10 contracts, while the lifting and abutting cylinder 20 of the 6-meter lifting and abutting mechanism 11 extends. Then start the device. After the large-diameter pipeline 9 is cut to a fixed length by the cutting machine, it is pushed by the pipeline pusher extruded from the left end extruder and transported continuously to the right along the pipe outlet nylon idler wheel 2. When the large-diameter pipeline 9 is pushed and transported to the rightmost end of the overall frame 1, it is sensed by the pipe turning induction photoelectric sensor transmitter 12 and the pipe turning induction photoelectric sensor receiver 13. At this time, multiple groups of lifting and pipe turning mechanisms 14 on the overall frame act together. The lifting and pipe turning cylinder 22 acts and extends to drive the lifting and pipe turning frame 21 to move upward, and the large-diameter pipeline 9 slides along the inclined plane of the lifting and pipe turning frame 21 into the pipe turning connection plate 6. At this time, due to the abutting effect of the corresponding pipe length abutting fixed plate and the abutting polyurethane buffer pad, the large-diameter pipeline 9 is separated from the extruded pipeline.

[0051] Then the separated whole large-diameter pipeline 9 falls onto the measuring nylon idler wheel 5 along the pipe turning connection plate 6. During this process, the pipe turning fixed baffle 8 and the pipe turning polyurethane buffer pad 7 intercept the large-diameter pipeline 9 to prevent it from rolling out from the rear end of the overall frame 1 due to inertia. Then the lifting and pipe turning cylinder 22 contracts to drive the lifting and pipe turning frame 21 to return to its original position. The measuring device at the rear end measures the end face size and length of the large-diameter pipeline 9. After the measurement is completed, it is grabbed by the rear-end grabbing mechanism and sent to the subsequent packaging process. The device then waits for the next large-diameter pipeline to be pushed to the rightmost end of the overall frame. The device operation is completed.

[0052] Its main working mode is composed of the set overall frame 1, the lifting and pipe turning cylinder 22, the lifting and pipe turning cylinder fixing frame 23, the lifting and pipe turning frame 21, etc., which are combined together. The lifting and pipe turning frame 21 is fixed on the moving block of the lifting and pipe turning cylinder 22 and is driven by the lifting and pipe turning cylinder 22 to move up and down to form a practical anti-adhesion abutting plate device for large-diameter pipelines of multiple specifications.
