Description

Technical Field

[0001] This utility model relates to the field of pipe grinding technology, specifically to a processing and grinding equipment for PVC pipes. Background Technology

[0002] PVC pipe polishing typically involves fine processing of the cut edges after pipe cutting. Because the cut edges of PVC pipes often have burrs, flash, and unevenness, these defects can seriously affect the sealing and stability of the pipe connections, potentially leading to problems such as leaks. Therefore, the polishing process is crucial.

[0003] For example, the utility model patent with announcement number CN219666085U discloses a grinding device for the production of PVC power pipes. An electric slide rail is embedded in one side of the top of the support base, and the two ends of the bottom of the mounting base are slidably connected to the moving groove. A connecting round plate is fixedly sleeved on the output shaft of the grinding motor, and a grinding round plate is fixedly sleeved on one side of the connecting round plate. Through the grinding column installed on the grinding round plate, when the grinding motor drives the grinding round plate to rotate and grind the pipe opening, the grinding column can grind both the inner and outer surfaces of the pipe opening edge at the same time, preventing deformation or burrs at the pipe opening edge, reducing the workload. Furthermore, by rotating the threaded rod, the grinding column can be moved, thereby quickly adapting to power pipes of different thicknesses and improving grinding efficiency.

[0004] However, it was discovered during actual use that the device moves two sets of grinding columns by using a threaded rod to bring the grinding columns close to the opening of the PVC pipe, and uses the grinding disc to rotate the grinding columns to grind the pipe cut.

[0005] However, the grinding column of this device has a small adjustable range, making it difficult to adapt to PVC pipes of different sizes. Furthermore, the grinding column is inconvenient to replace during long-term use, affecting the grinding effect. Therefore, it is necessary to design a PVC pipe processing and grinding equipment that is highly practical and adaptable to PVC pipes of different sizes. Utility Model Content

[0006] The purpose of this invention is to provide a processing and grinding equipment for PVC pipes to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a PVC pipe processing and grinding equipment, including a base plate, two limiting seats are fixedly installed on the top surface of the base plate, and a pipe fixing seat is provided inside each of the two limiting seats. A rotating assembly connected to the pipe fixing seat is provided on the top surface of the base plate. An adjusting seat is fixedly installed on the top surface of the base plate, and a threaded slider is provided inside the adjusting seat. A rectangular plate is fixedly installed at the front end of the threaded slider. Two mounting plates are fixedly installed on the front side of the rectangular plate, and multiple return springs are fixedly installed on the side of the two mounting plates that are close to each other. A grinding plate is fixedly installed on the end of the multiple return springs that is away from the mounting plate.

[0008] According to the above technical solution, the rotating assembly includes a circular external gear ring, a motor support, a drive motor, and a gear. The outer surface of the pipe fixing seat is fixedly mounted with the circular external gear ring. The motor support is fixedly mounted on one side of the limiting seat. The top surface of the motor support is fixedly mounted with the drive motor. The drive end of the drive motor is fixedly mounted with a gear, and the gear meshes with the circular external gear ring.

[0009] According to the above technical solution, the outer surface of the pipe fixing seat is threaded with two fastening screws, and the bottom ends of the two fastening screws extend into the interior of the pipe fixing seat. A rotating handwheel is fixedly installed on the outer surface of the fastening screws near the top.

[0010] According to the above technical solution, a limiting ring is fixedly installed on the outer surface of the pipe fixing seat, and a limiting groove corresponding to the limiting ring is opened on the inner wall surface of the limiting seat, and the outer surface of the limiting ring is inserted into the inside of the limiting groove.

[0011] According to the above technical solution, multiple roller supports are installed in an equally spaced array on the inner wall surface of the pipe fixing seat, and auxiliary rollers are rotatably connected inside each of the multiple roller supports.

[0012] According to the above technical solution, arc-shaped scrapers are fixedly installed on the left and right sides of the grinding plate, respectively.

[0013] According to the above technical solution, mounting holes are provided on the top surface of the base plate near the corners.

[0014] According to the above technical solution, a rubber pad is fixedly installed at the bottom end of the fastening screw.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: When operating this utility model, the PVC pipe to be ground is first pushed into the pipe fixing seat. The grinding plate is raised and lowered by adjusting the rotation of the screw inside the adjusting seat so that the grinding plate is aligned with the opening of the PVC pipe. Then, the fixing screw is tightened to lock the pipe. When the PVC pipe is inserted between the two grinding plates with arc-shaped structures on both sides, the return spring drives the grinding plate to open outward to adapt to the pipe diameter. Then, the spring continues to apply pressure to make the grinding plate fit tightly against the cut surface. Then, after the operator starts the rotating component, the pipe fixing seat carries the PVC pipe to rotate synchronously. The sandpaper and arc-shaped scraper at the bottom of the grinding plate can treat the burrs and flash at the cut of the rotating PVC pipe. The scraper first removes large particles of flash to reduce sandpaper wear, while the sandpaper finely grinds the remaining protrusions. This device can be compatible with PVC pipes of different diameters through screw height adjustment and spring adaptive clamping, realizing the integrated operation of rapid positioning and burr removal of PVC pipe cuts.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5The present invention provides a technical solution: a PVC pipe processing and grinding equipment, including a base plate 1, wherein an installation hole 17 is provided on the top surface of the base plate 1 near the corner; through the installation hole 17, it is convenient for personnel to use bolts to pass through the inside to install and fix the base plate 1 on a suitable PVC pipe grinding operating table or other carrier, thus facilitating the subsequent grinding operation of the PVC pipe.

[0024] Please see Figure 1-4 Two limiting seats 2 are fixedly installed on the top surface of the base plate 1, and each of the two limiting seats 2 has a pipe fixing seat 3 inside. A rotating component 4 connected to the pipe fixing seat 3 is provided on the top surface of the base plate 1. Multiple roller brackets 14 are installed in an evenly spaced array on the inner wall of the pipe fixing seat 3, and auxiliary rollers 15 are rotatably connected inside the multiple roller brackets 14. The two limiting seats 2 are used to support the pipe fixing seat 3, which facilitates subsequent rotation under the drive of the rotating component 4. The pipe fixing seat 3 is used to limit and fix the PVC pipe, which is convenient for subsequent grinding operations. The auxiliary rollers 15 are used to facilitate the entry and exit of the PVC pipe, improving convenience.

[0025] Please see Figure 1-4 Two fastening screws 11 are threadedly connected to the outer surface of the pipe fixing seat 3, and the bottom ends of both fastening screws 11 extend into the interior of the pipe fixing seat 3. A rubber base pad 18 is fixedly installed at the bottom end of the fastening screw 11, and a rotating handwheel is fixedly installed near the top outer surface of the fastening screw 11. With the fastening screws 11 and the rubber base pad 18, when the PVC pipe enters the interior of the pipe fixing seat 3, the personnel tighten the fastening screws 11, so that the rubber base pad 18 contacts the top outer surface of the PVC pipe and applies a downward force to it. This helps to maintain the stability of the PVC pipe and prevents it from moving during subsequent grinding.

[0026] Please see Figure 1-5 A limiting ring 12 is fixedly installed on the outer surface of the pipe fixing seat 3. A limiting groove 13 corresponding to the limiting ring 12 is opened on the inner wall surface of the limiting seat 2. The outer surface of the limiting ring 12 is inserted into the inside of the limiting groove 13. Through the cooperation of the limiting ring 12 and the limiting groove 13, the pipe fixing seat 3 is more stable when rotating.

[0027] Please see Figure 1-3The rotating assembly 4 includes a circular external gear ring 401, a motor support 402, a drive motor 403, and a gear 404. The circular external gear ring 401 is fixedly installed on the outer surface of the pipe fixing seat 3. The motor support 402 is fixedly installed on one side of the limiting seat 2. The drive motor 403 is fixedly installed on the top surface of the motor support 402. The gear 404 is fixedly installed on the drive end of the drive motor 403. The gear 404 meshes with the circular external gear ring 401. The drive motor 403 drives the gear 404 to rotate, so that the circular external gear ring 401 drives the pipe fixing seat 3 and the PVC pipe that is limited and fixed inside to rotate, which facilitates the subsequent grinding operation of the PVC pipe.

[0028] Please see Figure 1-3 An adjusting seat 5 is fixedly installed on the top surface of the base plate 1. A threaded slider 6 is provided inside the adjusting seat 5. A rectangular plate 7 is fixedly installed at the front end of the threaded slider 6. A lead screw is rotatably connected inside the adjusting seat 5 through a bearing. The threaded slider 6 is threadedly connected to the lead screw, and the lead screw is driven by a motor. This makes it easy for the threaded slider 6 to drive the rectangular plate 7 to move up and down to adjust the height. The threaded slider 6 is a rectangular threaded block, and its side is close to the inner wall of the adjusting seat 5, so that it will not rotate when moving up and down.

[0029] Please see Figure 1-3 Two mounting plates 8 are fixedly installed on the front side of the rectangular plate 7. Multiple return springs 9 are fixedly installed on the side of the two mounting plates 8 that are close to each other. A grinding plate 10 is fixedly installed on the end of the multiple return springs 9 that is away from the mounting plate 8. Arc-shaped scrapers 16 are fixedly installed on the left and right sides of the grinding plate 10. The return springs 9 facilitate the grinding plate 10 to grind the end cut of the PVC pipe. A sandpaper adhesive sheet is installed at the bottom of the grinding plate 10, and sandpaper is glued to the bottom of the sandpaper adhesive sheet. The sandpaper can be selected as coarse or fine grit as needed. When the end cut of the PVC pipe is located between the two grinding plates 10, the sandpaper is in contact with the end cut of the PVC pipe. When the PVC pipe rotates, the sandpaper can effectively grind the outside and inside of the end cut.
