Description

Technical Field

[0001] This utility model relates to the field of pipe cutting technology, and in particular to a polytetrafluoroethylene pipe cutting and positioning device. Background Technology

[0002] Polytetrafluoroethylene (PTFE) is an engineering plastic with excellent chemical resistance, low coefficient of friction, and good electrical insulation properties, widely used in chemical, pharmaceutical, food, and electronics industries. When cutting PTFE pipes, a PTFE pipe cutting and positioning device is typically used.

[0003] For example, a polytetrafluoroethylene (PTFE) tube processing device with publication number CN221271285U relates to the field of fluoroplastic product processing technology. It includes a support plate, a clamping assembly mounted on the surface of the support plate, equidistantly arranged positioning elements mounted on the surface of the support plate and inside the clamping assembly, a chip removal assembly mounted on the surface of the support plate and to one side of the positioning elements, a cutting assembly fixedly connected to the surface of the support plate and to one side of the clamping assembly, and a scale fixedly connected to the surface of the support plate and at the bottom of the cutting assembly. The clamping assembly includes a base fixed to the surface of the support plate. The PTFE tube processing device provided by this utility model, by incorporating the clamping assembly, can solve the problem of PTFE tubes shaking due to the friction of the cutting blade. Shaking of the PTFE tube leads to deviations in the cutting position of the cutting blade, resulting in inaccurate cutting specifications of the PTFE tube. However, due to the fact that the clamping components of this PTFE tube processing equipment clamp and fix the PTFE tube, it is not convenient to move the PTFE tube to cut it, and the PTFE tube cannot be rotated. When cutting large PTFE tubes, the cutting efficiency is low.

[0004] Therefore, a PTFE pipe cutting and positioning device has been developed that can automatically transport PTFE pipes and improve the cutting efficiency of large PTFE pipes. Utility Model Content

[0005] To overcome the shortcomings of existing PTFE pipe processing equipment, such as inconvenience in moving PTFE pipes for cutting and inability to rotate PTFE pipes, resulting in low cutting efficiency when cutting large PTFE pipes, this utility model provides a PTFE pipe cutting and positioning device that can automatically transport PTFE pipes and improve the cutting efficiency of large PTFE pipes.

[0006] A polytetrafluoroethylene (PTFE) pipe cutting and positioning device includes a base, a connecting plate, a first motor, a housing, a cutting machine, a lead screw, a guide rod, a conveying assembly, and a rotating assembly. Two connecting plates are connected to the front of the base, and the housing is connected to the inner side of the lower part of the base. The first motor is connected to the right side of the housing, and a lead screw is connected to the output shaft of the first motor. The lead screw is rotatably connected to the housing, and the cutting machine is threaded onto the lead screw. A guide rod is connected to the upper part of the housing, and the cutting machine is slidably connected to the guide rod. The connecting plate is equipped with a conveying assembly for conveying the pipe, and a rotating assembly for rotating the pipe is also provided on the connecting plate.

[0007] Furthermore, it is particularly preferred that the conveying assembly includes clamps, connecting rods, connecting blocks, a second cylinder, a frame, rollers, a third motor, and a second belt. The frame is connected to the upper side of the middle of the connecting plate, and two clamps are slidably connected to the upper side of the frame. The connecting rods are rotatably connected to the front and rear sides of the clamps. The second cylinder is connected to the upper side of the middle of the frame, and a connecting block is connected to the telescopic end of the second cylinder. The connecting rods are rotatably connected to the adjacent connecting blocks. The lower part of the clamps is rotatably connected to the front and rear rollers. The second belt is wound around the two adjacent rollers through a transmission wheel. The lower inner side of the clamps is connected to the third motor, and the output shaft of the third motor is connected to the adjacent rollers.

[0008] Furthermore, it is particularly preferred that the rotating assembly includes wheels, a first belt, a first cylinder, a first box, a second motor, and a fixed frame. Multiple wheels are rotatably connected to both the front and rear parts of the connecting plate, and a rotating shaft is provided between each pair of adjacent front and rear wheels. Two first cylinders are connected to the upper middle part of the base. The first box is slidably and detachably connected to the left and right sides of the rear part of the base. A second motor is connected to the upper rear part of the connecting plate. The rotating shafts are connected to the output shafts of the adjacent second motors via a first belt through a transmission wheel. A fixed frame is connected to the telescopic end of each first cylinder. Multiple wheels are rotatably connected to the lower side of the fixed frame, and a connecting shaft is provided between each pair of adjacent front and rear wheels.

[0009] Furthermore, it is particularly preferred that the first box has a handle.

[0010] In addition, it is particularly preferred that the device also includes a vacuuming assembly, which includes a second box, a suction head, and an air pump. The second box is slidably and detachably connected to the lower left side of the base, the suction head is connected to the middle of the base, and the air pump is connected to the middle of the base. The air pump is located below the suction head and is connected to the suction head and the second box.

[0011] Furthermore, it is particularly preferred that the first cylinder, the first motor, the second motor, the second cylinder, the third motor, the air pump, the cutting machine, and the processor are electrically connected through a control module.

[0012] The beneficial effects are as follows: 1. By starting the second motor, the first belt rotates and drives the shaft to rotate, causing the lower wheel to rotate, which in turn causes the polytetrafluoroethylene pipe to rotate, and then the cutting machine cuts the pipe, thus achieving the effect of improving the cutting efficiency of large polytetrafluoroethylene pipes.

[0013] 2. This utility model starts a third motor to drive the rollers to rotate, and the second belt causes the other rollers to rotate, thus conveying the polytetrafluoroethylene tube backward to a certain length for cutting. This achieves the effect of automatically conveying the polytetrafluoroethylene tube, saving manpower and improving cutting efficiency.

[0014] 3. This utility model uses an air pump to draw the dust generated during cutting into a second box, thus keeping the work area clean. Attached Figure Description

It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0025] A polytetrafluoroethylene pipe cutting and positioning device, such as Figures 1-8 As shown, the device includes a base 1, a connecting plate 101, a first motor 8, a housing 19, a cutting machine 21, a lead screw 22, a guide rod 23, a conveying assembly, and a rotating assembly. The front of the base 1 is connected to two connecting plates 101 on the left and right sides. The housing 19 is connected to the inner side of the lower part of the base 1. The first motor 8 is connected to the right side of the housing 19. The lead screw 22 is connected to the output shaft of the first motor 8. The lead screw 22 is rotatably connected to the housing 19. The cutting machine 21 is threadedly connected to the lead screw 22. The guide rod 23 is connected to the upper part of the housing 19. The cutting machine 21 is slidably connected to the guide rod 23. The connecting plate 101 is equipped with a conveying assembly and a rotating assembly.

[0026] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the conveying assembly includes clamps 3, connecting rods 10, connecting blocks 11, second cylinders 12, frames 13, rollers 14, third motors 15, and second belts 20. Frames 13 are connected to the upper middle part of the connecting plate 101. Two clamps 3 are slidably connected to the upper part of the frames 13. Connecting rods 10 are rotatably connected to the front and rear sides of the clamps 3. Second cylinders 12 are connected to the upper middle part of the frames 13. Connecting blocks 11 are connected to the telescopic ends of the second cylinders 12. Connecting rods 10 are rotatably connected to adjacent connecting blocks 11. Two rollers 14 are rotatably connected to the lower part of the clamps 3. The second belt 20 is wound around the two adjacent rollers 14 through a transmission wheel. The third motor 15 is connected to the inner lower part of the clamps 3. The output shaft of the third motor 15 is connected to the adjacent rollers 14.

[0027] like Figures 1-3As shown, the rotating assembly includes wheels 2, a first belt 4, a first cylinder 5, a first box 6, a second motor 9, and a fixed frame 16. The connecting plate 101 is rotatably connected to four wheels 2 at both the front and rear. A rotating shaft is provided between each pair of adjacent wheels 2. The upper middle part of the base 1 is connected to two first cylinders 5 on the left and right. The left and right sides of the rear part of the base 1 are slidably connected to the first box 6. The first box 6 is provided with a handle for easy gripping. The upper rear part of the connecting plate 101 is connected to the second motor 9. The rotating shaft is connected to the output shaft of the adjacent second motor 9 through a transmission wheel and the first belt 4 is wound around it. The telescopic end of the first cylinder 5 is connected to the fixed frame 16. The lower part of the fixed frame 16 is rotatably connected to four wheels 2. A connecting shaft is provided between each pair of adjacent wheels 2.

[0028] When using this utility model, first place the base 1 in the PTFE pipe cutting area, then place two PTFE pipes on the connecting plate 101 respectively, and place the PTFE pipes between the wheels 2. After placement, the processor starts the first cylinder 5 through the control module to push the fixing frame 16 downward, so that the wheels 2 on the fixing frame 16 contact the PTFE pipe. When placing the PTFE pipe, the PTFE pipe passes between two adjacent clamps 3. Then start the second cylinder 12 to drive the connecting block 11 downward, so that the clamps 3 come closer to each other to clamp the PTFE pipe. When it is necessary to cut the PTFE pipe, start the third motor 15 to drive the roller 14 to rotate. The second belt 20 causes the other rollers 14 to rotate, and the PTFE pipe is transported backward for a certain length for cutting. This achieves the function of automatically transporting PTFE pipe, saving manpower and improving cutting efficiency. During cutting, the processor starts the first motor 8 through the control module, which drives the lead screw 22 to rotate, so that the cutting machine 21 moves along the guide rod 23 to cut the polytetrafluoroethylene pipe. The cut pipe enters the first box 6. When cutting large PTFE pipes, the processor starts the second motor 9 through the control module, which drives the shaft to rotate through the first belt 4, causing the lower wheel 2 to rotate, which in turn causes the PTFE pipe to rotate, and then the cutting machine 21 to cut the pipe, thereby improving the cutting efficiency of large PTFE pipes.

[0029] like Figure 1 and Figure 7As shown, it also includes a vacuuming assembly, which includes a second box 7, a suction head 17, and an air pump 18. The second box 7 is slidably and detachably connected to the lower left side of the base 1.

The air pump 18 is located below the suction head 17 and is connected to the suction head 17. The air pump 18 is connected to the second box 7. The first cylinder 5, the first motor 8, the second motor 9, the second cylinder 12, the third motor 15, the air pump 18, the cutter 21, and the processor are electrically connected through a control module.

[0030] When cutting pipes, the air pump 18 can be activated to suck the dust generated during cutting into the second box 7, so as to keep the work area clean.
