Description

Technical Field

[0001] This utility model application relates to the technical field of grinding devices, specifically a grinding device for PTFE pipe production. Background Technology

[0002] PTFE pipe, also known as polytetrafluoroethylene pipe, is a high-performance plastic pipe made of tetrafluoroethylene monomer. It has a very wide operating temperature range, and can be used safely in a temperature range of -80℃ to 260℃ or even wider. It is suitable for highly corrosive gases and liquids at high temperatures, as well as media that are not suitable for transporting by other types of steel-plastic composite pipes and metal pipes.

[0003] When welding flanges after cutting the end face of PTFE pipe, the end face needs to be ground in order to ensure its flatness. In the process of grinding with traditional grinding equipment, the debris generated by grinding can easily enter the inside of the pipe, making subsequent cleaning of the pipe inconvenient. Summary of the Invention

[0004] To address the problem that existing grinding devices used in PTFE pipe production generate debris that easily enters the pipe and is difficult to clean, this invention provides a grinding device for PTFE pipe production to solve the aforementioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A grinding device for PTFE pipe production includes a support base. Two support bases are symmetrically connected to a support roller via bearings. A servo motor is installed on one side of each support base. The output end of the servo motor rotates through the support base and is fixedly connected to one of the support rollers. Adjustable side plates are fixed to the top surfaces of both support bases. An adjustable limit roller is connected to the inner side of the adjustment side plate away from the servo motor. A fan is fixed to the bottom surface of the limit roller near the end of the adjustment side plate. An adjustable grinding roller is connected to the inner side of the other adjustment side plate. The air outlet of the fan faces the servo motor.

[0007] Furthermore, an interval pad is slidably provided on the inner side of the adjustment side plate near the servo motor end, and an adjustment cross plate is slidably provided on the side of the interval pad away from the adjustment side plate, and the end of the adjustment cross plate is detachably fixedly connected to the grinding roller.

[0008] Furthermore, limit sliders are fixed on both sides of the spacer pad and on the side of the limit roller near the fan. The limit sliders are slidably connected to the adjustment grooves opened inside the adjustment cross plate and the adjustment side plate, respectively. A connecting screw is fixed on the side of the two limit sliders away from the spacer pad. A fixing clamp is threaded onto one end of the connecting screw extending to the outside of the adjustment side plate and the adjustment cross plate.

[0009] Furthermore, a positioning block is fixed to one end of the grinding roller facing the adjusting horizontal plate, a fixing screw is fixed to the other end of the positioning block away from the grinding roller, and a fixing clamping block 2 is threaded onto one end of the fixing screw extending to the outside of the adjusting horizontal plate.

[0010] Furthermore, the thickness of the grinding roller is greater than the thickness of the connecting screw, and the adjusting plate has a rectangular hole inside that mates with the positioning block, the thickness of the positioning block being less than the thickness of the rectangular hole.

[0011] Furthermore, each of the connecting screws is configured as a horizontally placed T-shape, the width of the fixing clamp and the spacer plate is greater than the width of the adjustment groove, each of the limiting sliders is configured as a rectangle that cooperates with the adjustment groove, and the thickness of each limiting slider is less than the thickness of the adjustment groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, the dust generated during grinding is blown out by a fan, preventing the dust from entering the pipe. The fan size can be adjusted according to the pipe diameter, which solves the problem that the dust generated during grinding in existing PTFE pipe production grinding devices easily enters the pipe and is inconvenient to clean, thus improving the practicality and applicability of the grinding device.

[0014] 2. In this utility model, the adjustable design of the grinding roller and the limiting roller makes it easy to adapt to the grinding of pipes of different diameters, thus improving the applicability of the grinding device. Furthermore, the detachable design of the grinding roller allows for individual alignment and replacement of the grinding roller after it is severely worn, thereby improving the service life of the grinding device while ensuring the grinding effect.

[0021] Reference Figure 1 , Figure 2 and Figure 3 A grinding device for PTFE pipe production includes a support base 1. Two support bases 1 are symmetrically connected by bearings to support rollers 2. A servo motor 3 is mounted on one side of each support base 1. The output end of the servo motor 3 rotates through the support base 1 and is fixedly connected to one of the support rollers 2. Adjustable side plates 4 are fixed to the top surfaces of both support bases 1. An adjustable limit roller 5 is connected to the inner side of the adjustable side plate 4 away from the servo motor 3. A fan 16 is fixed to the bottom surface of the limit roller 5 near the end of the adjustable side plate 4. The other adjustable side plate 1... An adjustable grinding roller 7 is connected to the inner side of the side plate 4. A positioning block 13 is fixed to one end of the grinding roller 7 facing the adjusting horizontal plate 6. The thickness of the grinding roller 7 is greater than the thickness of the connecting screw 11. A rectangular hole that mates with the positioning block 13 is opened inside the adjusting horizontal plate 6. The thickness of the positioning block 13 is less than the thickness of the rectangular hole. A fixing screw 14 is fixed to one end of the positioning block 13 away from the grinding roller 7. A fixing clamp 15 is threaded onto one end of the fixing screw 14 extending to the outside of the adjusting horizontal plate 6. The air outlet of the fan 16 faces the servo motor 3.

[0022] Specifically, during grinding, the pipe is placed between two support rollers 2, and then the limiting roller 5 is adjusted so that it fits against the top surface of the pipe, and the fan 16 is positioned on the side of the pipe. The servo motor 3 is turned on, and the grinding roller 7 is adjusted so that it fits against the side of the pipe. After fitting, the servo motor 3 and the fan 16 are turned on, so that the servo motor 3 drives the pipe to rotate and rub against the grinding roller 7. At the same time, the fan 16 blows out the debris generated during grinding. When the grinding roller 7 needs to be replaced, the fixing clamp 15 is turned to pull out the positioning block 13 and the fixing screw 14, so that the grinding roller 7 can be replaced.

[0023] As an optimization scheme, an interval pad 8 is slidably provided on the inner side of the adjustment side plate 4 near the servo motor 3. An adjustment horizontal plate 6 is slidably provided on the side of the interval pad 8 away from the adjustment side plate 4. The end of the adjustment horizontal plate 6 is detachably fixedly connected to the grinding roller 7. Limiting sliders 10 are fixed on both sides of the interval pad 8 and on the side of the limiting roller 5 near the fan 16. The limiting sliders 10 are slidably connected to the adjustment grooves 9 opened inside the adjustment horizontal plate 6 and the adjustment side plate 4, respectively. A connecting screw 11 is fixed on the side of the two limiting sliders 10 away from the interval pad 8. Each connecting screw 11 is set as a horizontally placed T-shape. The width of the fixing clamp 12 and the interval pad 8 is greater than the width of the adjustment groove 9. Each limiting slider 10 is set as a rectangle that cooperates with the adjustment groove 9. The thickness of each limiting slider 10 is less than the thickness of the adjustment groove 9. The end of the connecting screw 11 extending to the outside of the adjustment side plate 4 and the adjustment horizontal plate 6 is threaded with the fixing clamp 12.

[0024] Specifically, when it is necessary to adjust the position of the grinding roller 7 and the limiting roller 5, turn the fixing block 12 to release the clamping and fixing of the fixing block 12 on the adjusting side plate 4 or the adjusting horizontal plate 6, so that the position of the limiting roller 5 and the grinding roller 7 can be adjusted. During the adjustment, pull the limiting slider 10 to slide inside the adjusting groove 9. After the adjustment is completed, turn the fixing block 12 to re-clamp and fix the adjusting side plate 4 or the adjusting horizontal plate 6.
