Description

Technical Field

[0001] The utility model relates to a grinding device, in particular to a grinding device for pipes. Background Technique

[0002] Plastic pipes are pipes made of various plastic materials. Common types of plastic pipes include: PVC (polyvinyl chloride) pipes, PE (polyethylene) pipes, PP (polypropylene) pipes, PB (polybutene) pipes, etc. These pipes are widely used in multiple fields such as water supply and drainage systems, gas transmission, agricultural irrigation, chemical liquid transmission, wire and cable sleeves, etc. Compared with traditional metal pipes or cement pipes, plastic pipes have significant advantages such as light weight, corrosion resistance, simple installation, and low cost.

[0003] The grinding of plastic pipes is usually to prepare the surface of pipe fittings for bonding, welding or other types of connections, or to repair the defects on the surface of pipe fittings. Grinding can remove burrs, unevenness or oxide layers on the surface of plastic pipes, providing a smoother and cleaner surface, thereby enhancing the adhesion of adhesives or improving the welding quality. However, the existing plastic pipe grinding devices are designed for pipe fittings of specific sizes, which means that when encountering pipe fittings of different specifications, tools may need to be replaced or settings adjusted, reducing the adaptability and working efficiency of the equipment, that is, lacking versatility and flexibility.

[0004] Therefore, it is necessary to design a grinding device for pipes to solve the above technical problems. Content of the Utility Model

[0005] In order to overcome the shortcoming that the existing plastic pipe grinding devices are designed for pipe fittings of specific sizes and may need to replace tools or adjust settings when encountering pipe fittings of different specifications, the technical problem to be solved is: to provide a grinding device for pipes.

[0006] The technical solution is: A grinding device for pipes, including a base, a fixed box, a fixing plate, a material placing plate, a limiting block, a first motor, a grinding wheel, a second motor, a screw rod, a pulley and a flat belt. Fixed boxes are fixedly connected to the front and rear sides of the top of the base. Fixing plates and material placing plates are fixedly connected to the tops of the two fixed boxes. The fixing plates are located on the left side of the material placing plates. Screw rods are rotatably connected inside the two fixed boxes. A second motor is fixedly connected to the right front side of the top of the base. The output shaft of the second motor is fixedly connected to the front screw rod. Pulleys are fixedly connected to the right ends of the two screw rods. A flat belt is wound around between the two pulleys. Limiting blocks are threadedly connected to the two screw rods. A first motor is fixedly connected to the rear side of the base. A grinding wheel is fixedly connected to the output shaft of the first motor.

[0007] Further, it also includes a first roller, a second roller and a third motor. At least one first roller is annularly arrayed on the left sides of the two limit blocks. A third motor is fixedly connected to the top of the front fixing plate, and a second roller is fixedly connected to the output shaft of the third motor.

[0008] Further, it also includes a blower and a collection box. The blower is fixedly connected to the left side wall of the base, and the collection box is slidably connected to the rear side of the top of the base. Both the blower and the collection box are located between the grinding wheel and the rear fixing box.

[0009] Further, it also includes a shield. The shield is fixedly connected to the top of the base, and the shield is located directly above the collection box.

[0010] Further, it also includes a scale plate. The scale plates are fixedly connected to the front, rear, left and right side walls of the two fixing boxes.

[0011] Further, the bottom of the base is fixedly connected with anti-slip rubber.

[0012] Beneficial effects: 1. In the present utility model, the output shaft of the first motor drives the grinding wheel to rotate, effectively realizing the grinding of plastic pipes. Through the cooperation of components such as limit blocks, the second motor and the screw rod, the distance between the fixing plate and the limit blocks is adjusted, achieving the effect of adapting to plastic pipes of different specifications, and effectively improving the adaptability of the equipment.

[0013] 2. In the present utility model, the second roller drives the plastic pipe to rotate continuously while being ground, effectively making the pipe orifice of the plastic pipe be ground evenly.

Specific embodiments

[0021] The technical solution of the present utility model will be further described below with reference to the accompanying drawings.

[0022] Embodiment: A grinding device for pipes, as Figures 1-4 shown, includes a base 1, a fixed box 2, a fixing plate 3, a material placing plate 4, a limit block 5, a first motor 6, a grinding wheel 7, a second motor 8, a screw 9, a pulley 10, a flat belt 11, a first roller 501, a second roller 16, and a third motor 17. Fixed boxes 2 are connected to the front and rear sides of the top of the base 1 by screws. Anti-slip rubber is glued to the bottom of the base 1. Fixing plates 3 and material placing plates 4 are connected to the left sides of the tops of the two fixed boxes 2 by screws. The fixing plate 3 is located on the left side of the material placing plate 4, and the right side of the fixing plate 3 is in contact with the left side of the material placing plate 4. Screws 9 are rotatably connected inside the two fixed boxes 2. A second motor 8 is installed on the front right side of the top of the base 1 by screws. The output shaft of the second motor 8 is fixedly connected to the front screw 9. Pulleys 10 are fixedly connected to the right ends of the two screws 9. A flat belt 11 is wound around the two pulleys 10. A limit block 5 is threadedly connected to the two screws 9. A first motor 6 is installed on the rear side of the base 1 by screws. A grinding wheel 7 is fixedly connected to the output shaft of the first motor 6. Four first rollers 501 are annularly arranged on the left side of each of the two limit blocks 5. A third motor 17 is installed on the top of the front fixing plate 3 by screws. A second roller 16 is fixedly connected to the output shaft of the third motor 17.

[0023] First, place the device horizontally at the designated working location. Then, the staff member first measures the outer diameter length of the pipe orifice of the plastic pipe to be polished. When the outer diameter length of the pipe orifice of the plastic pipe is the same as the length of the material placing plate 4, the polishing work of the plastic pipe can begin. Subsequently, place the plastic pipe on the top of the material placing plate 4, and then push the plastic pipe from front to back, causing the pipe orifice at the rear end of the plastic pipe to closely adhere to the inner wall of the baffle 14. At this time, the plastic pipe is located between the fixed plate 3 and the limit block 5 and is in a state of being limited by the limit block 5. Then, the staff member turns on the first motor 6 and the third motor 17. At this time, the output shaft of the first motor 6 drives the grinding wheel 7 to rotate, and the output shaft of the third motor 17 drives the second roller 16 to rotate. When the grinding wheel 7 rotates, it polishes the pipe orifice of the plastic pipe. When the second roller 16 rotates, it contacts the surface of the plastic pipe and drives the plastic pipe to continuously rotate. Since there are four first rollers 501 annularly arranged on the left side of the two limit blocks 5, the plastic pipe contacts the first rollers 501 when rotating and drives the first rollers 501 to rotate. At this time, the frictional force between the plastic pipe and the first rollers 501 is relatively small, making it easier for the second roller 16 to drive the plastic pipe to rotate. When the plastic pipe is being polished, it is both limited between the fixed plate 3 and the limit block 5, and the outer surface of the pipe orifice of the plastic pipe can be evenly polished. When the pipe orifice at one end of the plastic pipe is polished, the staff member can remove the plastic pipe. If it is necessary to polish the other end of the plastic pipe, the staff member turns the plastic pipe to the direction to be polished, then places the plastic pipe on the top of the material placing plate 4 and repeats the above polishing actions. Since the pipe orifice diameters of the plastic pipes have different specifications, when the outer diameter length of the pipe orifice of the plastic pipe to be polished is greater than the distance between the fixed plate 3 and the limit block 5, the staff member should first measure the corresponding distance through the scale plate 15, that is, first measure the outer diameter length of the pipe orifice of the plastic pipe, and then measure the distance that the limit block 5 should move to the right. After measuring the corresponding distances, start the second motor 8 to make it work. At this time, the output shaft of the second motor 8 drives the front screw rod 9 to rotate clockwise, and the front screw rod 9 drives the pulley 10 on it to rotate clockwise, causing the rear pulley 10 and the screw rod 9 to rotate through the rotation of the flat belt 11. At this time, the limit block 5 moves to the right through the clockwise rotation of the screw rod 9, causing the limit block 5 to gradually move away from the fixed plate 3, that is, the distance between the fixed plate 3 and the limit block 5 becomes longer. When the distance that the limit block 5 moves to the right is the measured distance to be moved, turn off the second motor 8. At this time, the screw rod 9 stops rotating, causing the limit block 5 to stop moving to the right. Subsequently, place the plastic pipe on the top of the material placing plate 4 again and repeat the above actions.

[0024] Such as Figure 1 , Figure 3 and Figure 5As shown in the figure, it further includes a fan 12, a collection box 13, a baffle 14 and a scale plate 15. The left side wall of the base 1 is installed with a fan 12 by screws. The collection box 13 is slidably connected to the rear side of the top of the base 1. A handle is fixedly connected to the right side of the collection box 13 for pushing and pulling the collection box 13. Both the fan 12 and the collection box 13 are located between the grinding wheel 7 and the fixed box 2 at the rear. The baffle 14 is connected to the top of the base 1 by screws. The baffle 14 is located directly above the collection box 13. The scale plates 15 are connected to the front and rear side walls of the two fixed boxes 2 by screws.

[0025] During the process of grinding plastic pipes, start the fan 12 so that it is always in a working state. Since there are burrs and oxide layers on the surface of the plastic pipes, when the grinding wheel 7 grinds the plastic pipes, the abrasive grains of the grinding wheel will cut the burrs and oxide layers on the surface of the plastic pipes into fine particles or fibrous waste chips. At the same time, the waste chips generated when the grinding wheel 7 grinds the plastic pipes will fly into the air. At this time, the fan 12 on the left blows the generated waste chips to the right. At the same time, under the action of the baffle 14, when the flying particles or fibrous waste chips contact the baffle 14, because the waste chips are blocked by the baffle 14, the waste chips will fall into the collection box 13 under their own gravity. When there is a lot of waste chips collected in the collection box 13, the staff can pull the collection box 13 out to the right through the handle on the right side of the collection box 13, and pour the waste chips in the collection box 13 concentratedly at a designated place. Then push the collection box 13 back to its initial state. When the device stops grinding the plastic pipes, turn off the fan 12, the first motor 6 and the third motor 17.

[0026] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
