Description

Technical Field

[0001] This utility model relates to the field of PE pipe production technology, and in particular to a grinding device for PE pipe production. Background Technology

[0002] PE pipe (polyethylene pipe) is a thermoplastic pipe made primarily of polyethylene resin. It features corrosion resistance, low-temperature resistance, good toughness, light weight, and easy installation. According to its application, it is divided into water supply pipes, drainage pipes, gas pipes, etc., and is widely used in municipal engineering, building water supply and drainage, agricultural irrigation, and other fields.

[0003] Before fusion splicing, both ends of PE pipes need to be polished. Traditional polishing methods rely heavily on manual operation using scrapers, resulting in low efficiency. Although various polishing devices are available on the market, they still require manual re-flipping of the PE pipe to complete the polishing, and these devices are not compatible with PE pipes of different diameters. Furthermore, a large amount of waste accumulates in the polishing area during the process, affecting the polishing effect. Therefore, we propose a polishing device for PE pipe production.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0027] Reference Figures 1-8This utility model provides a technical solution: a grinding device for PE pipe production, including a workbench 1 and a discharge module. A grinding box 2 is arranged above the workbench 1. A rotating cylinder 3 is connected through the inside of the grinding box 2. A first driven gear 4 is connected to one end of the rotating cylinder 3 near the outside of the grinding box 2. A first motor 5 is arranged on one side of the grinding box 2. A driving gear 6 is connected to the output end of the first motor 5. The driving gear 6 meshes with the first driven gear 4. A second driven gear 30 is meshed with the other side of the first driven gear. Two sets of electric push rods 7 are connected to the other end of the rotating cylinder 3. A connecting block 8 is connected to the output end of the electric push rod 7. A second motor 9 is installed on one side of the connecting block 8. A rotating component 10 is connected to the output end of the second motor 9. A second scraper 12 is connected to the outside of the rotating component 10. A first scraper 11 is connected to one side of the connecting block 8. A feeding mechanism is arranged on one side of the grinding box 2. The feeding mechanism includes a limiting platform 16. The limiting platform 16 has a limiting hole 17 inside; a feeding motor 18 is provided on one side of the limiting platform 16, and a roller 20 is connected to the output end of the feeding motor 18. A transmission belt 19 is connected to the outer side of one end of the roller 20, and the transmission belt 19 connects multiple sets of rollers 20 to form a synchronous rotation structure; a fixing frame 21 is provided on one side of the grinding box 2, and a third motor 22 is provided on one side of the fixing frame 21. A lead screw 23 is connected to the output end of the third motor 22, and the threads on both sides of the lead screw 23 are positive threads and negative threads, respectively. Multiple sets of sliders 24 are connected to the outer side of the lead screw 23, and a first clamp 25 is connected to one side of the slider 24; a discharge motor 27 is provided on one side of the discharge hole 15. The structure of the discharge module is the same as that of the feeding mechanism. The output end of the discharge motor 27 is also connected to another set of rollers 20 and the transmission belt 19; a cylinder 28 is provided on the side of the grinding box 2 near the discharge hole 15, and a second clamp 29 is connected to the pushing end of the cylinder 28.

[0028] In practical implementation, when using this device to grind the ends of PE pipes, the PE pipe is first manually passed through the limiting hole 17 of the limiting platform 16. At this time, the feeding motor 18 is started. The rotation of the feeding motor 18 drives the roller 20 to rotate, and the transmission belt 19 connected to the outside of the roller 20 drives multiple sets of rollers 20 to rotate. The PE pipe is transported through the rollers 20 to the bottom of the fixed frame 21. Then, the third motor 22 is started. The rotation of the third motor 22 drives the lead screw 23 to rotate, which in turn drives the slider 24 to move. Because the threads on both sides of the lead screw 23 are forward and reverse threads respectively, it can achieve relative reverse movement of the two sets of sliders 24. Through the movement of the sliders 24, the bottom connection can be driven. The first clamp 25 moves to provide auxiliary support for the PE pipe, allowing it to accurately enter the grinding box 2. Once one end of the PE pipe is inside the grinding box and the end requiring grinding is below the electric push rod 7, the first clamp 25 clamps the PE pipe to prevent movement. The electric push rod 7 pushes the first scraper 11 against the outer wall of the PE pipe. At this point, the second motor 9 is activated. The rotation of the second motor 9 drives the connecting rotating part 10 connected to its output end to rotate, causing the second scraper 12 to rotate to one side of the inner wall of the PE pipe. The rotating part 10 is initially in a horizontal position, so it does not affect the transport of the PE pipe, and it can rotate 360°. During operation, the second scraper 12 is also in contact with the inner wall of the PE pipe. Since the inner side of the PE pipe does not require extensive grinding, only a small amount of grinding is needed in the outer area, the second scraper 12 does not need to penetrate deep into the inner side of the PE pipe. After the scraper is fixed, the first motor 5 is started. The rotation of the first motor 5 drives the drive gear 6 to rotate, which in turn drives the first driven gear 4 meshing with it to rotate. The rotation of the first driven gear 4 drives the rotating cylinder 3 to rotate. The second driven gear 30 on the other side of the first driven gear 4 provides stable support for the rotating cylinder 3 during rotation, ensuring normal operation of the rotation. The rotation of the first driven gear 4 drives the grinding mechanism at the other end of the rotating cylinder 3 to rotate, thereby grinding the PE pipe. The port is polished. After polishing, the rotating part 10 returns to its initial position, the first clamp 25 releases its clamping of the PE pipe, and the PE pipe moves and enters the discharge module through the discharge hole 15. The structure of the discharge module is the same as that of the feeding mechanism. Both are driven by a motor to operate multiple sets of rollers 20. The discharge motor 27 is started so that the PE pipe continues to be transported. When the other end of the PE pipe comes to the bottom of the electric push rod 7, the cylinder 28 pushes the second clamp 29 to fix the PE pipe. At this time, the rotating part 10 rotates in the opposite direction so that the second scraper 12 contacts the inner wall of the PE pipe from the other side and works with the polishing mechanism to polish the other end of the PE pipe. After polishing, the fixation of the PE pipe is released, and the discharge is completed.The above operations make it easy to use this device.

[0029] Example 2

[0030] Reference Figure 1 and Figure 8 This embodiment is an optimization based on embodiment 1. A blower 13 is connected to the top of the grinding box 2, and a discharge hole 15 is opened on one side of the grinding box 2. A brush 14 is connected inside the discharge hole 15. A waste bin 26 is connected through the bottom of the workbench 1, and the waste bin 26 is connected to the bottom of the grinding box 2.

[0031] In practice, when dealing with the waste generated during grinding, the blower 13 is activated during the grinding process. The airflow blows the waste to the bottom, where it is collected in the waste bin 26. This prevents waste from accumulating and affecting the scraper's operation or contaminating the grinding surface, thus improving grinding accuracy. Furthermore, as the PE pipe passes through the discharge hole 15, the brush 14 inside the discharge hole 15 removes any residual waste from the surface, ensuring pipe cleanliness and preventing waste from overflowing and contaminating the working environment. The grinding box 2 also protects against waste splashing during grinding, preventing it from affecting the cleanliness of the workbench 1. These operations facilitate the cleaning of waste generated during grinding.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
