Description

Technical Field

[0001] The present invention relates to the technical field of PE water supply pipe processing, in particular to a batch processing device for producing PE water supply pipes. Background Art

[0002] With the acceleration of urbanization and the growing demand for water resource management, efficient and reliable water supply systems have become an indispensable part of modern urban construction. Polyethylene (PE) water pipes are widely used in water supply projects due to their excellent corrosion resistance, good flexibility, and long service life. However, despite their many advantages, PE pipes still face some challenges in practical application, particularly in terms of sealing and joint strength at pipe joints.

[0003] During installation, PE water pipes typically need to be connected to other pipes or fittings at both ends. To ensure the tightness and strength of these connections, effective measures must be taken to improve the adhesion between the connecting material (such as glue or hot-melt adhesive) and the pipe. Traditional connection methods sometimes fail to meet high engineering standards, especially in harsh underground environments. Leakage or breakage at these connections can easily affect the safety and stability of the entire pipe system.

[0004] To address these issues, one effective technology is to perform a skinning treatment on the ends of PE water pipes during production. Specifically, the smooth outer plastic layer is removed mechanically or chemically, exposing a rougher surface. This roughening improves the adhesion of subsequent coatings or adhesives, thereby enhancing the seal and strength of the joints and extending the service life of the pipe. The application of this skinning technology in PE water pipe production not only addresses the seal and strength issues of joints but also improves the overall performance of the piping system, possessing significant practical significance.

[0005] Although rotary scrapers capable of scraping PE water pipes are currently available, existing rotary scrapers still require manual rotation of the blade holder to drive the scraper for uniform scraping along the pipe surface. Furthermore, each time scraping is performed, the depth of the scraper's insertion into the pipe's outer surface must be manually adjusted to achieve the desired scraping effect. Therefore, existing rotary PE pipe scrapers rely on manual operation to scrape the outer surface. This method is not only inefficient but also difficult to ensure consistent processing quality and precision, making it unsuitable for scraping large quantities of PE pipe outer surface.

The front and rear inner walls of 82 are connected with movable blocks 781, and the two movable blocks 781 are respectively slidably connected in the two slide grooves 76. The front and rear sides of the upper part of the sliding seat 782 are slidably connected with sliding rods 783. The right ends of the two sliding rods 783 are connected with an arc-shaped pressure block 784 for pressing down the connecting rod 75. A spring 3 785 is sleeved on the sliding rod 783. The two ends of the spring 3 785 are respectively connected to the arc-shaped pressure block 784 and the sliding seat 782. The left side of the sliding seat 782 is rotatably connected with a nut 77 through a bearing. The outer wall of the hollow rotating shaft 71 is provided with an external thread that cooperates with the nut 77. A pushing member for pushing the arc-shaped pressure block 784 to press down the connecting rod 75 is provided on the mounting seat 6. A driving member for driving the hollow rotating shaft 71 to rotate is provided on the mounting seat 6. The driving member includes a motor 712 installed on the right side of the mounting seat 6, and a gear 713 is connected to the outer wall of the hollow rotating shaft 71 and the output shaft of the motor 712. The two gears 713 are meshed, and the pushing member includes an electric telescopic rod 79 embedded in the mounting seat 6. The electric telescopic rod 79 is located in front of the gear 713. A push ring 710 is connected to the electric telescopic rod 79. The push ring 710 is located on the right side of the arc pressure block 784 and contacts the arc pressure block 784. A sliding rod 711 is slidably connected to the mounting seat 6. The sliding rod 711 is located on the rear side of the gear 713. The sliding rod 711 is connected to the push ring 710 for guiding the push ring 710. A hollow tube 61 is embedded in the mounting seat 6. The hollow tube 61 is located in the hollow rotating shaft 71.The hollow tube 61 and the push plate 5 are both provided with an inner support fixture 8 for supporting the tube.

[0035] The PE water pipe is placed on the lifting bracket 3, which can be used to lift the PE water pipe, ensuring that the center of the circle of PE water pipes of different diameters is aligned with the center of the circle of the hollow rotating shaft 71. This can accommodate PE water pipes of different diameters and achieve the scraping of PE water pipes of different diameters. The distance between the base 1 and the base 2 is adjustable, so that the position of the components on the base 1 and the base 2 can be adjusted, thereby accommodating PE water pipes of different lengths. By turning the nut 77, the nut 77 can drive the sliding seat 782 to move to the left. The sliding seat 782 moves to the left, which pulls the arc pressure block 784 to move to the left through the spring three 785. The arc pressure block 784 moves to the left and presses the connecting rod 75 downward, so that the connecting rod 75 pulls the lifting plate 73 and the scraper 74 to move downward, and the spring two 70 is compressed accordingly. At the same time, the electric telescopic rod 79 is controlled to drive the push ring 710 to move to the left and keep it in close contact with the arc pressure block 784, so that the arc pressure block 784 keeps pressing the connecting rod 75, preventing the lifting plate 73 from pushing itself and driving the scraper 74 upward under the action of the spring two 70. When it is necessary to raise the scraper 74, first control the electric telescopic rod 79 to drive the push ring 710 to move right and reset, and then reverse the nut 77 so that the nut 77 drives the sliding seat 782 to move right. The sliding seat 782 moves to the right and pushes the arc pressure block 784 to move right through spring three 785. Under the reset action of spring two 70, the lifting plate 73 is pushed to move up with the scraper 74, and the connecting rod 75 swings upward accordingly; the height of the scraper 74 is adjustable, which can ensure that the scraper 74 contacts the outer surface of PE water supply pipes of different diameters, adapts to PE water supply pipes of different diameters, and realizes scraping of PE water supply pipes of different diameters.

[0036] After the height of the scraper 74 is adjusted, the electric slide 4 is controlled to drive the push plate 5 with the inner support clamp 8 thereon to move to the right. The inner support clamp 8 on the push plate 5 is then inserted into the PE water supply pipe. When the push plate 5 moves to the right until it contacts the PE water supply pipe, the push plate 5 continues to move to the right, pushing the PE water supply pipe to the right and contacting the scraper 74. The PE water supply pipe is then sleeved on the inner support clamp 8 of the hollow tube 61. The inner support clamp 8 is then controlled to open to support and clamp the PE water supply pipe, preventing deformation of the end area of ​​the PE water supply pipe from affecting the subsequent outer skin scraping work, and can also prevent the PE water supply pipe from rotating and affecting the subsequent outer skin scraping work. Then, the electric telescopic rod 79 is controlled to drive the push ring 710 to move to the left by an appropriate distance. The push ring 710 moves to the left, pushing the arc-shaped pressure block 784 to move to the left and press the connecting rod 75 downward. The spring 3 785 is then compressed. The connecting rod 75 then pulls the lifting plate 73 and the scraper 74 downward by an appropriate distance. The spring 2 70 is compressed, so that the scraper 74 can cut into the outer surface of the PE water supply pipe to an appropriate depth, ensuring that the outer skin of the PE water supply pipe end is subsequently removed. Then, the motor 712 is controlled to work, and the hollow shaft 71 is driven to rotate through the transmission of the gear 713. The components on the hollow shaft 71 rotate accordingly, so that the scraper 74 can rotate along the PE water supply pipe and scrape off the outer skin of the PE water supply pipe end. When the scraper 74 rotates at least one circle, the electric slide 4 is controlled to drive the push plate 5 to drive the inner support clamp 8 on it to move to the left, thereby driving the PE water supply pipe to move to the left, completing the removal of the outer skin of the PE water supply pipe end.

[0037] After the outer skin of one end of the PE water supply pipe is removed, the electric telescopic rod 79 is first controlled to drive the push ring 710 to move rightward and reset. Under the reset action of the spring three 785, the arc-shaped pressure block 784 is pushed to move rightward and reset. Under the reset action of the spring two 70, the lifting plate 73 is pushed upward with the scraper 74. Then, the inner support clamp 8 is controlled to close to loosen the PE water supply pipe, and then the PE water supply pipe is turned around. Then, the above operation is repeated to complete the removal of the outer skin of the other end of the PE water supply pipe. In this way, the device can support the PE water supply pipe through the lifting support 3, support and clamp the PE water supply pipe through the inner support clamp 8, and drive the hollow shaft 71 to drive the scraper 74 to rotate along the PE water supply pipe through the cooperation of the motor 712 and the gear 713 to remove the outer skin of the PE water supply pipe end. The device has a high degree of automation and stable processing quality. It is suitable for large-scale PE pipe outer skin scraping, improves processing efficiency, and can ensure consistent processing quality and precision.

[0038] See also Figure 10-12The inner support fixture 8 includes a cylinder body 81 and a connecting plate 82. The left end of the hollow tube 61 and the upper part of the vertical plate 51 are connected to the cylinder body 81. The cylinder body 81 on the left side passes through the vertical plate 51 and the cross plate 52. The hollow tube 61 is connected to the cylinder body 81. Three connecting plates 82 are hinged on the outer wall of the cylinder body 81 at even intervals along the circumference. A support plate 83 for supporting the pipe is hinged on the connecting plate 82. A sliding ring 84 is slidingly sleeved on the outer wall of the cylinder body 81. Three connecting plates 85 are hinged on the outer wall of the sliding ring 84 at even intervals along the circumference. The connecting plates 85 are hinged to the corresponding support plates 83. Three guide grooves 86 are evenly spaced along the circumference on the cylinder body 81. A piston rod 88 is provided in a sliding manner in the cylinder body 81, and a sliding block 87 and a sealing ring 89 are respectively connected to the two ends of the piston rod 88. The sealing ring 89 is used to seal the gap between the piston rod 88 and the inner wall of the cylinder body 81 to prevent gas leakage. The sliding block 87 is in the shape of a herringbone. The herringbone sliding block 87 extends out of the guide groove 86 and is connected to the sliding ring 84. The length of the piston rod 88 is longer than the length of the guide groove 86. Rollers 10 are rotatably provided on the right support plate 83 at even intervals from left to right. The rollers 10 can reduce the friction between the right support plate 83 and the inner wall of the pipe, so that the pipe can move smoothly to the left along the right support plate 83.

[0039] The left cylinder 81 and the hollow tube 61 are connected to the air pump via a hose. The air pump is controlled to input external gas into the cylinder 81. The gas pushes the piston rod 88, which drives the sliding block 87 toward the connecting plate 1 82, thereby driving the sliding ring 84 toward the connecting plate 1 82. In turn, the connecting plate 2 85 pushes the support plate 83 outward to contact the inner wall of the PE water supply pipe, thereby supporting and clamping the PE water supply pipe. Because the length of the piston rod 88 is longer than the length of the guide groove 86, the piston rod 88 can continuously block the guide groove 86 after moving toward the connecting plate 1 82, preventing the gas in the cylinder 81 from leaking from the guide groove 86, thereby ensuring stable support and clamping of the PE water supply pipe. Controlling the air pump to extract the gas in the cylinder 81 can enable the piston rod 88 to drive the sliding block 87 to move away from the connecting plate 1 82, thereby driving the sliding ring 84 to move away from the connecting plate 1 82, and then enabling the connecting plate 2 85 to pull the support plate 83 inward to loosen the PE water pipe.

[0040] See also Figure 13The lifting support frame 3 includes a cylinder 1 31 and a connecting plate 32. Two front and rear cylinders 1 31 are installed on the base 1 and the base 2 2. The cylinder 1 31 is connected to the connecting plate 32. Two left and right guide rods 33 are connected between the front and rear connecting plates 32. Two front and rear support blocks 34 are slidably connected between the two guide rods 33. The support blocks 34 are used to support the pipes. The top of the support blocks 34 is arc-shaped, which can better fit the pipes. Two front and rear springs 1 35 are mounted on the guide rod 33. The two ends of the spring 1 35 are respectively connected to the support block 34 and the connecting plate 32. The top of the support block 34 is connected to a sponge pad 36 for buffering and protecting the pipes.

[0041] The PE water supply pipe is placed on the support block 34. Since the top of the support block 34 is curved, the weight of the PE water supply pipe can push the support blocks 34 on the front and back sides away from each other, and the spring 1 35 is compressed accordingly. This can adapt to supporting PE water supply pipes of different diameters. The support block 34 with a curved top can limit the PE water supply pipe to prevent it from shifting forward and backward. The control cylinder 1 31 drives the connecting plate 32 to rise and fall, which can cause the guide rod 33 to drive the support block 34 to rise and fall, thereby driving the PE water supply pipe to rise and fall, ensuring that the center of the circle of PE water supply pipes of different diameters can be aligned with the center of the circle of the hollow rotating shaft 71, so that PE water supply pipes of different diameters can be scraped.

[0042] See also Figure 8-Figure 9 , both the base 1 and the base 2 are provided with a loading and unloading mechanism, which includes a cylinder 2 91 and a telescopic ejector plate 92. A group of cylinders 2 91 is installed on both the base 1 and the base 2, and each group of cylinders 2 91 has two cylinders. The two cylinders 2 91 in each group are symmetrically arranged front to back. The two groups of cylinders 2 91 are located between the two lifting supports 3. Each group of cylinders 2 91 is connected to a telescopic ejector plate 92 for lifting the pipe. The telescopic ejector plate 92 includes a top plate 921 connected to the cylinder 2 91. A sliding groove is provided on the rear side of the top of the top plate 921. A top block 922 is slidably connected in the sliding groove. A screw 923 is rotatably connected to the rear side of the top of the top plate 921. The screw 923 is threadedly connected to the top block 922, and the top of the top plate 921 is connected with a baffle 93 for blocking the pipe. The top rear sides of the base 1 and the base 2 are connected with a guide slide 1 94, and the top front sides of the base 1 and the base 2 are connected with a guide slide 2 95. Guide slide 2 95 and guide slide 1 94 are both located on the outside of the two lifting supports 3. The side where guide slide 2 95 and guide slide 1 94 are close to each other are both inclined to guide the pipe downward to the lifting support 3. The rear side of guide slide 1 94 is provided with a storage rack 96 for storing pipes. The top of the top plate 921, the top block 922, the guide slide 1 94, the guide slide 2 95 and the storage rack 96 are all inclined with the front being low and the back being high.

[0043] The PE water supply pipe to be scraped is placed on the storage rack 96. The PE water supply pipe then slides forward along the inclined surface at the top of the storage rack 96. The PE water supply pipe on the storage rack 96 is blocked by the guide slide 1 94. The control cylinder 2 91 drives the telescopic lifting plate 92 to drive the baffle 93 to move up and down. The rise of the telescopic lifting plate 92 can not only lift the scraped PE water supply pipe on the lifting support 3 upward, but also lift the PE water supply pipe at the front end of the storage rack 96 upward. The PE water supply pipe to be scraped then slides forward along the inclined surface at the top of the telescopic lifting plate 92 to the top of the guide slide 1 94, and is then blocked by the baffle 93. The scraped PE water supply pipe then slides forward along the inclined surface at the top of the telescopic lifting plate 92 to the top of the guide slide 2 95, and then slides forward and downward along the inclined surface at the top of the guide slide 2 95. When the baffle 93 follows the telescopic ejector plate 92 downward and disengages the PE water supply pipe on top of the guide slide 94, the PE water supply pipe then slides forward and downward along the inclined surface of the top of the guide slide 94 onto the lifting support 3, thus achieving the effect of automatic loading and unloading, improving the degree of automation and further enhancing processing efficiency. The screw 923 can be rotated to adjust the front and rear position of the ejector block 922 to accommodate PE water supply pipes of different diameters, ensuring that the telescopic ejector plate 92 can accurately lift a PE water supply pipe on the storage rack 96 each time.
