Description

Technical Field

[0001] The utility model relates to the technical field of PE coiled core pipe grinding, in particular to a double-end surface grinding device for PE coiled core pipes. Background Art

[0002] PE roll-core pipe is a tubular core material made of polyethylene as raw material, also known as polyethylene roll-core pipe. PE roll-core pipe is mainly made of polyethylene resin, has good toughness and corrosion resistance, and has good heat resistance and pressure resistance. During the production process, some defects may appear on the surface of PE roll-core pipe, such as scratches and unevenness. Polishing can remove the rough part of the surface of PE roll-core pipe, making its surface smoother, thereby improving the overall appearance quality of the product.

[0003] The grinding of PE coiled core pipe is to use coarser sandpaper or grinding wheel for preliminary grinding to remove large particles, burrs and obvious unevenness on the surface. On the basis of preliminary grinding, use finer sandpaper or grinding wheel for fine grinding to further smooth the surface and improve the finish. After grinding, use a cleaning cloth or detergent to remove the grinding residue on the surface to keep the surface clean and tidy.

[0004] However, manual polishing relies on the manual operation of workers, and its efficiency is usually lower than that of mechanical polishing. In large-scale production scenarios, manual polishing may not be able to meet the needs of fast and efficient production. The polishing process requires workers to exert continuous effort, which places high demands on workers' physical strength and endurance. Working for a long time can easily lead to fatigue and decreased efficiency. Utility Model Content

The grinding blade 4 is used to grind both ends of the PE core roll pipe, and a lifting platform 5 is fixedly connected to both sides of the operating frame 1. A clamping plate 6 that can be lifted and slid is provided at the bottom of the lifting platform 5. A clamping assembly for clamping the PE core roll pipe is provided on the surface of the clamping plate 6. The clamping assembly is used to clamp the PE core roll pipe to facilitate subsequent clamping and grinding. The clamping can quickly and accurately position and clamp the PE core roll pipe, reducing the time and error of manual adjustment, thereby improving the overall production efficiency;

[0029] The clamping assembly includes a No. 2 threaded rod 7 rotatably connected to the inner wall of the clamping plate 6, and sliding rods 8 are fixedly connected on both sides of the No. 2 threaded rod 7. The surfaces of the No. 2 threaded rod 7 and the sliding rod 8 are slidably connected to the No. 1 clamping rod 9. The bottom of the clamping plate 6 is fixedly connected to the No. 2 clamping rod 10, and the upper surface of the No. 1 clamping rod 9 is rotatably connected to the No. 1 rotating rod 11. The upper surface of the clamping plate 6 is rotatably connected to the No. 2 rotating rod 12. The above-mentioned parts can be clamped in an appropriate clamping manner according to the characteristics and processing requirements of the PE core tube, so as to effectively protect the surface of the PE core tube from damage. Automated grinding reduces manual participation, and workers do not need to perform repetitive and heavy grinding work for a long time, which reduces labor intensity. Automated equipment can operate continuously, which improves equipment utilization and production efficiency, and further reduces the production cost of unit products.

[0030] Example 2

[0031] Reference Figure 1-4 , which is the second embodiment of the present utility model, which is different from the first embodiment in that: a conveyor belt is provided on the inner side wall of the operating frame 1, which is used to transport the PE core pipe to facilitate subsequent processing operations, and a support frame is fixedly connected to the bottom of the operating frame 1, and a No. 1 motor 13 with an output end spline-connected to the surface of the grinding blade 4 is installed on the other side of the grinding plate 3, and a hydraulic rod 14 is fixedly connected to the side of the grinding plate 3 away from the grinding blade 4, and a cylinder 15 with an output end spline-connected to the surface of the hydraulic rod 14 is installed on the upper surface of the No. 1 fixed plate 2, and a spring 16 is fixedly connected to the inner side wall of the No. 1 fixed plate 2, and one end of the spring 16 is fixedly connected to a buffer plate 17, and the spring 16 and the buffer plate 17 are used to avoid long-term collision with the No. 1 fixed plate 2 when the grinding plate 3 finishes work and moves backward, causing wear, and at the same time can extend the service life of the product;

[0032] The inner side wall of the lifting platform 5 is fixedly connected with a U-shaped plate 19, and the inner top of the lifting platform 5 is rotatably connected to a No. 1 threaded rod 20. The upper surface of the lifting platform 5 is provided with a No. 2 motor 18 whose output end is splined with the surface of the No. 2 threaded rod 7. The surface of the No. 1 threaded rod 20 is threadedly connected to the surface of the clamping plate 6. Both sides of the clamping plate 6 are fixedly connected with a slide plate 21, and the slide plate 21 slides on the surface of the U-shaped plate 19. One end of the No. 2 threaded rod 7 and the sliding rod 8 is provided with a No. 2 fixed plate 22. The connection intersection of the No. 1 rotating rod 11 and the No. 2 rotating rod 12 is rotatably connected. One side of the No. 2 fixed plate 22 is installed with a No. 3 motor 23 whose output end is splined with the surface of the No. 2 threaded rod 7. The inner side wall of the No. 1 clamping rod 9 and the No. 2 clamping rod 10 is fixedly connected with an anti-skid pad. The anti-skid pad is made of rubber. The anti-skid pad is used to prevent slipping when the No. 1 clamping rod 9 and the No. 2 clamping rod 10 clamp the PE core pipe, which is convenient for subsequent grinding work.

[0033] The working process of this utility model is as follows:

[0034] The conveyor belt transports the PE core pipe, and then the staff starts the No. 2 motor 18 and the No. 3 motor 23. The No. 1 threaded rod 20 rotates, driving the clamping plate 6 to move up and down in the lifting platform 5. At the same time, the slide 21 moves in the U-shaped plate 19, and the No. 2 threaded rod 7 rotates. The No. 1 clamping rod 9 moves in the No. 2 threaded rod 7 and the sliding rod 8. As the distance between the No. 1 clamping rod 9 and the No. 2 clamping rod 10 is shortened, the No. 1 rotating rod 11 and the No. 2 rotating rod 12 are driven to rotate closer, and at the same time, the No. 1 clamping rod 9 can be assisted to move through precise lifting control and clamping. Force adjustment can achieve precise control of the grinding force and avoid surface quality problems of workpieces caused by excessive or insufficient force. The No. 1 clamping rod 9 and the No. 2 clamping rod 10 can clamp the PE core tube, and then the staff starts the No. 1 motor 13 and the cylinder 15, and the grinding blade 4 rotates to start grinding the clamped PE core tube. At the same time, the hydraulic rod 14 drives the grinding plate 3 to move. By adjusting the distance of the grinding blade 4, the contact point and contact force between the grinding blade 4 and the PE core tube can be accurately controlled, thereby ensuring the accuracy and consistency of grinding.
