Description

Technical Field

[0001] This utility model relates to the technical field of PVC-UH drainage pipe processing, and in particular to a PVC-UH drainage pipe cutting surface grinding device. Background Technology

[0002] PVC-UH drainage pipes are made primarily of sanitary-grade polyvinyl chloride resin, with added stabilizers and lubricants, and are produced through extrusion or injection molding. Their stable molecular chain structure provides excellent weather resistance and anti-aging properties, with a normal service life of over 50 years. During the cutting process, burrs, unevenness, or micro-cracks may occur on the cut surface of PVC-UH drainage pipes. These imperfections can affect the sealing of pipe connections, leading to leaks and other problems. Grinding can remove these imperfections, making the cut surface smoother and thus improving the sealing of the connection.

[0003] Chinese utility model patent document CN217800771U discloses a PE drainage pipe cutting and grinding device. It includes a grinding mechanism, the bottom of which is fixedly connected to a moving mechanism. A second mounting platform is fixedly connected to one side of the top of the moving mechanism. A clamping mechanism is fixedly connected to one side of the second mounting platform. The clamping mechanism includes a second base, one side of which is fixedly connected to the second mounting platform. Slide tracks are provided on both sides of the second base, and clamping blocks are slidably connected to the surfaces of the slide tracks. A driving mechanism is fixedly connected to one side of the second base. A limiting boss is fixedly connected to one end of the driving mechanism. A connecting rod is fixedly connected to one end of each clamping block, and one end of the connecting rod passes through another clamping block and is fixedly connected to a limiting plate.

[0004] When using the aforementioned PE drainage pipe cutting and grinding device, if the drainage pipe is long, it is easy for the drainage pipe to tilt due to gravity, resulting in poor grinding quality of the cut surface, which in turn affects the subsequent welding quality and connection sealing. Therefore, this utility model proposes a PVC-UH drainage pipe cutting and grinding device that is different from the existing technology to solve the above-mentioned technical problems. Summary of the Invention

[0005] To address the issue mentioned above where drainage pipes of considerable length tend to tilt due to gravity, resulting in poor surface grinding quality and consequently affecting subsequent welding quality and sealing, this invention provides a PVC-UH drainage pipe surface grinding device.

[0006] This utility model provides a PVC-UH drainage pipe cut surface grinding device, which adopts the following technical solution:

[0007] A PVC-UH drainage pipe cutting surface grinding device includes a working frame. A grinding component is installed at one end of the bottom of the inner cavity of the working frame. Multiple sets of sliding components are installed at the other end of the bottom of the inner cavity of the working frame. A U-shaped frame is installed on the upper surface of the multiple sets of sliding components. A cylinder is installed at the top and bottom of the inner cavity of the multiple sets of U-shaped frames. A U-shaped plate is installed at the output end of the multiple sets of cylinders. A horizontal frame overlaps the upper surface of the multiple sets of U-shaped frames. A horizontal plate is movably inserted through the inner cavity of the multiple sets of horizontal frames.

[0008] By adopting the above technical solution, the PVC-UH drain pipe to be ground is placed on the U-shaped plate on the lower side. The cylinder at the corresponding position is activated to extend and retract, so that the PVC-UH drain pipe can be tightly clamped and fixed by multiple sets of U-shaped plates. Then, the grinding component is activated and the PVC-UH drain pipe is pushed to move until the cut surface of the PVC-UH drain pipe can contact the outer wall of the grinding wheel, so that the grinding process can be carried out.

[0009] Optionally, the grinding assembly includes a pad, which is fixed at the bottom of the inner cavity of the working frame. A stepper motor is installed on the upper surface of the pad, and a grinding wheel is installed at the output end of the stepper motor.

[0010] Optionally, the sliding assembly includes a slide frame, which is welded to the bottom of the inner cavity of the working frame, and the slide frame is externally slidably fitted with a slide frame fixed to the bottom wall of the U-shaped frame.

[0011] By adopting the above technical solution, the stepper motor is started to drive the grinding wheel to rotate, and the staff pushes the PVC-UH drain pipe to one side of the grinding wheel until the cut surface of the PVC-UH drain pipe can contact the outer wall of the grinding wheel, so that the grinding process can be carried out.

[0012] Optionally, multiple sets of strip grooves are evenly formed on the upper surface of the horizontal plate, and T-shaped plates that engage with the strip grooves are movably inserted into the upper surface of the two sets of horizontal frames.

[0013] By adopting the above technical solution, the two sets of T-shaped plates are pulled out to separate them from the strip groove. Then, the two sets of U-shaped frames are pulled outward to drive the horizontal frame to slide synchronously on the outer wall of the horizontal plate to an appropriate length. Then, the T-shaped plates are reinserted to re-engage with the strip groove at the corresponding position. This allows for adjustment of the horizontal distance between the two sets of U-shaped frames, making it suitable for PVC-UH drainage pipes with larger lengths.

[0014] Optionally, a first upright plate is installed at one end of the bottom wall of the inner cavity of the working frame, and a stainless steel water pipe is fixedly embedded at the upper end of the first upright plate. One end of the stainless steel water pipe is connected to the tap water supply network, and a nozzle is installed at the other end of the stainless steel water pipe at an angle.

[0015] By adopting the above technical solution, the control valve on the stainless steel water pipe is opened during the grinding process, so that tap water can be sprayed out evenly and at a low speed through the stainless steel water pipe and nozzle. This can reduce the temperature of the PVC-UH drainage pipe during the grinding process with the help of tap water, and at the same time, the powder generated during the grinding process can be discharged.

[0016] Optionally, a wastewater hole is provided at one end of the bottom wall of the work frame, and a wastewater frame is provided below the work frame.

[0017] By adopting the above technical solution, the wastewater after use can be collected into the inner cavity of the wastewater frame through the wastewater hole, thus minimizing the possibility of wastewater flowing freely.

[0018] In summary, this utility model has at least one of the following beneficial effects:

[0019] During the polishing process, the control valve on the stainless steel water pipe is opened, allowing tap water to be sprayed out evenly and at a low speed through the stainless steel water pipe and nozzle. This helps to reduce the temperature of the PVC-UH drain pipe during the polishing process and also removes the powder from the polishing process.

[0020] Pull out the two sets of T-shaped plates to separate them from the strip groove, then pull the two sets of U-shaped frames outward to make the horizontal frame slide synchronously on the outer wall of the horizontal plate to the appropriate length. Then reinsert the T-shaped plates to make them re-engage with the strip groove at the corresponding position, thereby adjusting the horizontal distance between the two sets of U-shaped frames, which is convenient for use with longer PVC-UH drainage pipes.

[0024] The following is in conjunction with the appendix Figure 1-2 The present invention will be described in further detail below.

[0025] Please refer to the attached diagram in the instruction manual. Figure 1 and 2This utility model provides an embodiment of a PVC-UH drainage pipe cutting surface grinding device, including a working frame 10. The upper surface of the working frame 10 is set as an opening. A grinding component is installed at one end of the bottom of the inner cavity of the working frame 10. The grinding component includes a pad 3, which is fixed at the bottom of the inner cavity of the working frame 10. A stepper motor 2 is installed on the upper surface of the pad 3. A grinding wheel 1 is installed at the output end of the stepper motor 2. Multiple sets of sliding components are installed at the other end of the bottom of the inner cavity of the working frame 10. The sliding components include a slide 8, which is welded to the bottom of the inner cavity of the working frame 10.

[0026] Please refer to the attached diagram in the instruction manual. Figure 1 and 2 The longitudinal section of the slide 8 is set as an inverted U-shape. The slide frame 7 is slidably sleeved on the outside of the slide 8. A loop frame 12 is installed on the upper surface of multiple sets of slide frames 7. The lateral longitudinal section of the loop frame 12 is set as an open shape. Cylinders 9 are installed at the top and bottom of the inner cavity of multiple sets of loop frames 12. A U-shaped plate 11 is installed at the output end of multiple sets of cylinders 9. The lateral longitudinal section of the U-shaped plate 11 is set as U-shaped.

[0027] Place the PVC-UH drain pipe to be polished on the U-shaped plate 11 on the lower side, and activate the cylinder 9 at the corresponding position to extend and retract, so that the PVC-UH drain pipe can be tightly clamped and fixed by multiple sets of U-shaped plates 11. Then, start the stepper motor 2 to drive the polishing wheel 1 to rotate. The operator pushes the PVC-UH drain pipe to one side of the polishing wheel 1, so that the sliding frame 7 can be driven by the U-shaped frame 12 to slide synchronously on the outer wall of the slide frame 8 until the cut surface of the PVC-UH drain pipe can contact the outer wall of the polishing wheel 1, and then the polishing process can be carried out.

[0028] Please refer to the attached diagram in the instruction manual. Figure 1 and 2 A horizontal frame 13 is attached to the upper surface of multiple sets of rectangular frames 12. A horizontal plate 16 is movably inserted into the inner cavity of multiple sets of horizontal frames 13. The lateral longitudinal section of the horizontal plate 16 is set as I-shaped. Multiple sets of strip grooves 15 are evenly opened on the upper surface of the horizontal plate 16. T-shaped plates 14 that engage with the strip grooves 15 are movably inserted into the upper surface of two sets of horizontal frames 13.

[0029] Pull out the two sets of T-shaped plates 14 to separate them from the strip groove 15, then pull the two sets of loop frames 12 outward to drive the horizontal frame 13 to slide synchronously on the outer wall of the horizontal plate 16 to an appropriate length. Then reinsert the T-shaped plates 14 to re-engage them with the strip groove 15 at the corresponding position, thereby adjusting the horizontal distance between the two sets of loop frames 12, which is convenient for use with longer PVC-UH drainage pipes.

[0030] Please refer to the attached diagram in the instruction manual. Figure 1 and 2A first vertical plate 4 is installed at one end of the bottom wall of the inner cavity of the working frame 10. The first vertical plate 4 is located on the outside of the stepper motor 2 and the pad 3. A stainless steel water pipe 18 is fixedly embedded on the upper end of the first vertical plate 4. A control valve is installed on the outside of the stainless steel water pipe 18. One end of the stainless steel water pipe 18 is connected to the tap water supply network. A nozzle 17 is installed at an angle on the other end of the stainless steel water pipe 18.

[0031] Open the control valve on the stainless steel water pipe 18 so that tap water can be sprayed out evenly and at a low speed through the stainless steel water pipe 18 and the nozzle 17. This can reduce the temperature of the PVC-UH drain pipe during the polishing process and remove the powder from the polishing process.

[0032] Please refer to the attached diagram in the instruction manual. Figure 1 and 2 A wastewater hole 6 is provided at one end of the bottom wall of the working frame 10, and the wastewater hole 6 is located below the grinding wheel 1. A wastewater frame 5 is provided below the working frame 10, and the wastewater frame 5 is located directly below the wastewater hole 6. The upper surface of the wastewater frame 5 is open. Wastewater after use can be collected into the inner cavity of the wastewater frame 5 through the wastewater hole 6, so as to avoid wastewater from flowing freely.

[0033] Working principle: When using this PVC-UH drain pipe cutting surface grinding device, place the PVC-UH drain pipe to be ground on the U-shaped plate 11 on the lower side, start the cylinder 9 at the corresponding position to extend and retract, so that the PVC-UH drain pipe can be tightly clamped and fixed by multiple sets of U-shaped plates 11. Then, start the stepper motor 2 to drive the grinding wheel 1 to rotate. The operator pushes the PVC-UH drain pipe to one side of the grinding wheel 1, so that the sliding frame 7 can be driven by the U-shaped frame 12 to slide synchronously on the outer wall of the slide frame 8 until the cutting surface of the PVC-UH drain pipe can contact the outer wall of the grinding wheel 1, and then the grinding process can be performed.

[0034] During the polishing process, the control valve on the stainless steel water pipe 18 is opened, allowing tap water to be sprayed evenly and at a low speed through the stainless steel water pipe 18 and the nozzle 17. This helps to reduce the temperature of the PVC-UH drain pipe during the polishing process and also allows the powder produced during polishing to be discharged. Wastewater after use can be collected in the inner cavity of the wastewater frame 5 through the wastewater hole 6, minimizing the risk of wastewater flowing freely.

[0035] When grinding is required on a long PVC-UH drain pipe, first pull out the two sets of T-shaped plates 14 to separate them from the strip groove 15. Then pull the two sets of loop frames 12 outward to drive the horizontal frame 13 to slide synchronously on the outer wall of the horizontal plate 16 to the appropriate length. Then reinsert the T-shaped plates 14 to re-engage them with the strip groove 15 at the corresponding position. This allows adjustment of the horizontal distance between the two sets of loop frames 12, making it suitable for long PVC-UH drain pipes.

[0036] All standard parts used in this utility model document can be purchased from the market. Each component in this utility model document can be customized according to the description and drawings. The specific connection methods of each component adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.
