Description

Technical Field

[0001] This application relates to the field of plastic pipe manufacturing, and in particular to a pipe traction device. Background Technology

[0002] Pipe traction equipment is one of the core devices in a plastic pipe production line. It is mainly used to continuously pull extruded and cooled pipes to the cutting station. The pipes are directionally conveyed by clamping them with a traction belt. In industrial production, its traction stability and efficiency directly affect the forming quality and production efficiency of the pipes.

[0003] Existing traction equipment generally consists of a mechanical frame, a traction execution unit, and a clamping and adjusting mechanism. During clamping and traction, the pipe is led out from the cooling water tank and inserted into the traction port. The hydraulic rod is operated to press down the upper support frame, and the synchronous motor adjusts the spacing of the bottom support frame to form a three-point clamp. The traction motor drives the traction belt to rotate, and the pipe is pulled to move towards the cutting station.

[0004] In actual pipe production traction, after the pipe is cooled by the water tank, it needs to be sent into the traction equipment. After leaving the cooling water tank, water stains may be attached to the surface of the pipe. After entering the traction equipment, the pipe is prone to contact with mechanical parts. Long-term accumulation will lead to rust and wear of parts, shortening the service life of the equipment. Summary of the Invention

[0005] The purpose of this application is to address the problem mentioned in the background art that after the pipes are cooled in the water tank, they need to be sent into the traction equipment. After leaving the cooling water tank, water stains may adhere to the surface of the pipes. After entering the traction equipment, the pipes are prone to contact with mechanical parts, which can lead to corrosion and wear of parts and shorten the service life of the equipment over a long period of time. This application provides a pipe traction device.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A pipeline traction device includes a traction frame with traction ports at both ends. Three circumferentially distributed support frames are mounted on the traction frame, and traction belts are installed on the support frames. A traction motor is fixed to each of the three support frames, and the output end of the traction motor is connected to the traction belt. Sliding blocks are fixed to both ends of each support frame, and sliding rails are slidably connected to the sliding blocks. The sliding rails are fixedly connected to the traction frame. Two symmetrical hydraulic rods are fixed to the traction frame, and the telescopic ends of the two hydraulic rods are correspondingly fixedly connected to the sliding blocks at both ends of one of the support frames. A synchronizing rod is rotatably connected to the traction frame, and a synchronizing motor is fixed to the traction frame. The output end of the synchronous motor is connected to the synchronous rod. Both ends of the synchronous rod are fixed with synchronous gear one and synchronous gear two. Both ends of the traction frame are fixed with two symmetrical couplings. Synchronous gear three is connected to each coupling. A chain is connected between synchronous gear one, synchronous gear two and corresponding synchronous gear three on one end of the synchronous rod. A threaded rod is connected to the coupling. The threaded rod is threadedly connected to the corresponding sliding block. A water stain cleaning mechanism and an auxiliary cleaning mechanism are provided at one end of the traction frame. The water stain cleaning mechanism and the auxiliary cleaning mechanism are located at the same end of the traction frame.

[0008] By adopting the above technical solution, a water stain cleaning mechanism is installed at the traction port where the traction frame pipe enters. The water stain cleaning mechanism cleans the water stains remaining on the surface of the pipe. At the same time, the water stain cleaning mechanism drives an auxiliary cleaning mechanism to further clean and dry the pipe. This can clean the water stains on the surface of the pipe that is about to enter the traction equipment, reduce the contact between water stains and mechanical parts of the traction equipment, and prevent residual water stains from affecting the service life of the equipment. At the same time, cleaning the surface of the pipe reduces the possibility of foreign objects on the surface of the pipe, which may cause damage when the pipe surface is squeezed.

[0009] Furthermore, the water stain cleaning mechanism includes three cleaning rods arranged in a circle at one end of the traction frame. Each of the three cleaning rods has a cleaning head fixed at one end. The cleaning head corresponds to the traction port on the traction frame. A support and adjustment assembly is provided between the three cleaning rods and the traction frame. A rotating assembly is provided on the traction frame.

[0010] By adopting the above technical solution, the rotating component drives the support and adjustment component, which in turn moves the cleaning head on the pipe. This cleans the water stains on the surface of the pipe that is about to enter the traction equipment, reducing the contact between water stains and the mechanical parts of the traction equipment, which would otherwise affect the service life of the equipment. At the same time, it cleans foreign objects from the pipe, reducing the possibility of damage to the pipe surface when it is squeezed due to foreign objects on the pipe surface.

[0011] Furthermore, the support adjustment assembly includes a support ring one disposed on the traction frame, the middle of the three cleaning rods being rotatably connected to the support ring one, a support ring two disposed on the support ring one, and three circumferentially distributed support rails fixed on the support ring two, with the ends of the three cleaning rods away from the cleaning head being slidably connected to the corresponding support rails.

[0012] By adopting the above technical solution, the support ring rotates, which in turn drives the cleaning rod. The cleaning rod rotates on the support ring under the constraint of the support rail, thus making it easy to adjust the position of the cleaning head according to the pipe diameter of different pipe materials.

[0013] Furthermore, three circumferentially distributed connecting rods are fixed on the second support ring, and a support block is fixed on each connecting rod. The support block is slidably connected to the first support ring.

[0014] By adopting the above technical solution, the support block on the connecting rod supports the first support ring, thereby making it easy for the first support ring to rotate under the support of the second support ring.

[0015] Furthermore, an adjustment groove is provided on the first support ring, the adjustment groove corresponds to one of the support blocks, and an adjustment bolt is threaded onto the support block, the adjustment bolt abutting against the first support ring.

[0016] By adopting the above technical solution, the adjusting bolt on the support block abuts against the support ring one, and the support ring one is fixed by the adjusting bolt, so that the adjusted cleaning rod can easily drive the cleaning head to maintain the adjusted state.

[0017] Furthermore, the rotating assembly includes a rotating support ring fixed on the traction frame. The rotating support ring corresponds to and is rotatably connected to the second support ring. A drive motor is fixed at one end of the traction frame near the rotating support ring. A drive gear is fixed at the output end of the drive motor. Several circumferentially distributed gear grooves are provided on the second support ring. The drive gear meshes with the gear grooves on the second support ring.

[0018] By adopting the above technical solution, the drive gear drives the second support ring, the second support ring drives the connecting rod, the connecting rod drives the support block, and the support block drives the first support ring. This allows the first support ring to easily drive the cleaning head on the cleaning rod to rotate and scrape away water stains on the surface of the pipe.

[0019] Furthermore, the auxiliary cleaning mechanism includes a support air ring fixed to one end of the traction frame near the support ring one. The support air ring has several air inlets on the side near the support frame, and the air inlets penetrate the traction frame. Several circumferentially distributed air blowing pipes are fixed to the inner wall of the support air ring, and the air blowing pipes are connected to the support air ring. An air blowing assembly is provided between the support air ring and the support ring one.

[0020] By adopting the above technical solution, external air enters the supporting air ring through the air inlet and is then blown out through the air blower. The air blown out of the air blower is directed towards the surface of the pipe, thereby further reducing the possibility of residual water stains or foreign particles on the surface of the pipe. At the same time, it can blow away the scraped water and reduce the possibility of water stains coming into contact with the pipe again.

[0021] Furthermore, the blower assembly includes a rotating ring rotatably connected to a supporting air ring, a plurality of circumferentially distributed blower blades fixed on the rotating ring, the blower blades being located inside the supporting air ring, and a connecting ring fixed on the rotating ring, the connecting ring being fixedly connected to the supporting ring.

[0022] By adopting the above technical solution, when the second support ring rotates, the second support ring drives the fan blades on the rotating ring to rotate, so that the second support ring can drive the cleaning head to move while the air blower blows out air to clean water stains on the pipe.

[0023] Furthermore, the blower tube is tilted, and the tilting direction is towards the cleaning head.

[0024] By adopting the above technical solution, the air blower is designed to be inclined toward the cleaning head, which can further reduce the possibility of water stains entering the traction equipment.

[0025] In summary, this application includes at least one of the following beneficial effects;

[0026] 1. This application, when feeding the pipe into the traction port of the traction frame, utilizes a support adjustment assembly to drive three cleaning rods, which in turn move three cleaning heads simultaneously, according to the pipe's diameter. The cleaning heads on the cleaning rods contact the pipe surface, and during the pipe's traction movement, a rotating assembly drives the support adjustment assembly, which in turn drives the three cleaning rods. The cleaning rods then rotate the cleaning heads. The cleaning heads are made of rubber, reducing the possibility of damage to the pipe from contact with the cleaning heads. As the pipe moves, the cleaning heads rotate on the pipe, removing water stains from its surface. The process involves scraping away water while simultaneously rotating the fan blades to draw in external air into the support air ring, which is then blown out through the air pipe. This further cleans the surface of the pipe, preventing water stains from entering the traction equipment and reducing contact between residual water and the mechanical parts of the equipment. This minimizes the risk of residual water affecting the equipment's lifespan and reduces the possibility of watermarks forming on the pipe after drying. Simultaneously, it removes foreign objects from the pipe, reducing the possibility of damage to the pipe surface during compression, thus facilitating the pipe's traction and transport.

[0027] 2. In this application, by directly moving the support ring one, the support ring one drives the cleaning rod when it rotates. The end of the cleaning rod away from the cleaning head moves on the support rail, allowing the cleaning rod to rotate on the support ring one. This allows the cleaning rod to drive the cleaning head closer to or away from the center of the support ring one, thus achieving the purpose of conveniently adjusting the position of the cleaning head according to the pipe diameter of different pipe materials.

[0028] 3. In this application, when it is necessary for the support ring to rotate on the support block, the adjusting bolt is turned to move the adjusting bolt on the support block, so that the adjusting bolt is no longer in contact with the support ring. Then, the support ring is moved so that the adjusting bolt moves in the adjusting groove. When the support ring rotates to the appropriate position, the adjusting bolt is retightened so that the adjusting bolt is in contact with the support ring, thus fixing the support ring. This achieves the purpose of making it easy for the adjusted cleaning rod to drive the cleaning head to maintain the adjusted state. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0037] This application discloses a pipeline traction device.

[0038] Reference Figure 1 , Figure 2 and Figure 3A pipeline traction device includes a traction frame 1, with traction ports at both ends. Three circumferentially distributed support frames 2 are mounted on the traction frame 1, and traction belts 3 are installed on the support frames 2. Traction motors are fixed on each of the three support frames 2, and the output ends of the traction motors are connected to the traction belts 3. Sliding blocks 4 are fixed at both ends of each support frame 2, and sliding rails 5 are slidably connected to the sliding blocks 4. The sliding rails 5 are fixedly connected to the traction frame 1. Two symmetrical hydraulic rods 14 are fixed on the traction frame 1, and the telescopic ends of the two hydraulic rods 14 are correspondingly fixedly connected to the sliding blocks 4 at both ends of one of the support frames 2. A synchronizing rod 8 is rotatably connected to the traction frame 1, and a synchronous motor 9 is fixed on the traction frame 1. The output end is connected to the synchronous rod 8 for transmission. Both ends of the synchronous rod 8 are fixed with synchronous gear 10 and synchronous gear 2. Both ends of the synchronous rod 8 are fixed with synchronous gear 11. Both ends of the traction frame 1 are fixed with two symmetrical couplings 12. Both couplings 12 are connected with synchronous gear 3 15 for transmission. Synchronous gear 10, synchronous gear 2 11 and corresponding synchronous gear 3 15 on one end of the synchronous rod 8 are connected by a chain for transmission. Threaded rod 13 is connected to the coupling 12 for transmission. Threaded rod 13 is threadedly connected to the corresponding sliding block 4. A water stain cleaning mechanism 6 is provided at one end of the traction frame 1. An auxiliary cleaning mechanism 7 is provided at one end of the traction frame 1. The water stain cleaning mechanism 6 and the auxiliary cleaning mechanism 7 are located at the same end of the traction frame 1.

[0039] During the production of plastic pipes, the extruder extrudes the plastic into a shape and then feeds the pipe into a cooling water tank. After cooling, the pipe is pulled out of the cooling water tank and passes through the traction port of the traction frame 1. According to the diameter of the pipe, the synchronous motor 9 drives the synchronous rod 8. The synchronous rod 8 drives the synchronous gears 10 and 11 at both ends. The synchronous gears 10 and 11 drive the synchronous gear 3 15 of the corresponding coupling 12 via a chain. The coupling 12 drives the threaded rod 13, which in turn drives the corresponding sliding block 4. Block 4 moves within the sliding rail 5, causing the two lower support frames 2 to move towards or away from the traction port of the traction frame 1. This allows the traction belts 3 on the two lower support frames 2 to support the pipe. Then, the hydraulic rod 14 on the traction frame 1 pushes the sliding block 4 of the upper support frame 2, causing the traction belts 3 on the upper support frame 2 to press against the pipe. The traction motor on the support frame 2 drives the traction belts 3 to move, which in turn moves the pipe along the traction frame 1. Subsequent pipes are then pulled into the traction frame 1 and fed into the next... The pipe is cut using a pipe cutting device. As the pipe passes through the traction port on the traction frame 1, a water stain cleaning mechanism 6 on the traction frame 1 contacts the pipe. During the pipe's movement, the water stain cleaning mechanism 6 rotates on the pipe, scraping away any water stains remaining after passing through the cooling water tank. While the water stain cleaning mechanism 6 is cleaning the pipe, it also drives an auxiliary cleaning mechanism 7. The auxiliary cleaning mechanism 7 blows air onto the pipe surface, further reducing the possibility of residual water stains. This process is achieved by cutting the pipe through the traction frame 1. A water stain cleaning mechanism 6 is installed at the traction port to clean the water stains remaining on the surface of the pipe. At the same time, the water stain cleaning mechanism 6 drives the auxiliary cleaning mechanism 7 to further clean and dry the pipe. This can clean the water stains on the surface of the pipe that is about to enter the traction equipment, reduce the contact between water stains and mechanical parts of the traction equipment, and prevent residual water stains from affecting the service life of the equipment. At the same time, cleaning the surface of the pipe reduces the possibility of foreign objects on the surface of the pipe, which may cause damage when the pipe surface is squeezed.

[0040] Reference Figure 3 , Figure 4 and Figure 5 The water stain cleaning mechanism 6 includes three cleaning rods 61 arranged in a circle at one end of the traction frame 1. Each of the three cleaning rods 61 has a cleaning head 62 fixed at one end. The cleaning head 62 corresponds to the traction port on the traction frame 1. A support adjustment component 63 is provided between the three cleaning rods 61 and the traction frame 1. A rotating component 64 is provided on the traction frame 1.

[0041] When the pipe is fed into the traction port of the traction frame 1, the support adjustment assembly 63 drives the three cleaning rods 61 according to the pipe diameter. The three cleaning rods 61 then drive the three cleaning heads 62 to move simultaneously. Based on the pipe diameter, the cleaning heads 62 on the cleaning rods 61 contact the pipe surface. During the traction movement of the pipe, the rotation assembly 64 drives the support adjustment assembly 63, which in turn drives the three cleaning rods 61. The cleaning rods 61 then drive the cleaning heads 62 to rotate. The cleaning heads 62 are made of rubber to reduce contact with the pipe. To prevent damage to the pipe, the cleaning head 62 rotates on the pipe during its movement, scraping away water stains from its surface. By using the cleaning head 62 on the cleaning rod 61 to press against the pipe and move it along the pipe, the cleaning head 62 can clean the water stains on the surface of the pipe that is about to enter the traction equipment, reducing the contact between water stains and the mechanical parts of the traction equipment, which could affect the service life of the equipment. At the same time, it also cleans foreign objects from the pipe, reducing the possibility of damage to the pipe surface when it is squeezed due to foreign objects.

[0042] Reference Figure 4 and Figure 5 The support adjustment assembly 63 includes a support ring 631 mounted on the traction frame 1, three cleaning rods 61 rotatably connected to the support ring 631 at their middle parts, a support ring 632 mounted on the support ring 631, and three circumferentially distributed support rails 633 fixed on the support ring 632. The ends of the three cleaning rods 61 that are away from the cleaning head 62 are slidably connected to the corresponding support rails 633.

[0043] When adjusting the position of the cleaning head 62 on the cleaning rod 61, directly move the support ring 631. When the support ring 631 rotates, it drives the cleaning rod 61. The end of the cleaning rod 61 away from the cleaning head 62 moves on the support rail 633, allowing the cleaning rod 61 to rotate on the support ring 631. This causes the cleaning rod 61 to move the cleaning head 62 closer to or further away from the center of the support ring 631. By moving the support ring 631, the support ring 631 drives the cleaning rod 61, allowing the cleaning rod 61 to rotate on the support ring 631 under the constraint of the support rail 633. This makes it easy to adjust the position of the cleaning head 62 according to the pipe diameter of different pipe materials.

[0044] Reference Figure 4 and Figure 5Three circumferentially distributed connecting rods 634 are fixed on the second support ring 632. Support blocks 635 are fixed on the connecting rods 634, and the support blocks 635 are slidably connected to the first support ring 631. When the first support ring 631 is moved, the second support ring 632 supports the connecting rods 634, the connecting rods 634 support the support blocks 635, and the first support ring 631 rotates on the support blocks 635. By utilizing the support blocks 635 on the connecting rods 634 to support the first support ring 631, it is possible to easily allow the first support ring 631 to rotate under the support of the second support ring 632.

[0045] Reference Figure 4 and Figure 5 The support ring 631 has an adjustment groove 636, which corresponds to one of the support blocks 635. The support block 635 is threaded with an adjustment bolt 637, which abuts against the support ring 631.

[0046] When it is necessary for the support ring 631 to rotate on the support block 635, tighten the adjusting bolt 637 to move the adjusting bolt 637 on the support block 635, allowing the adjusting bolt 637 to disengage from the support ring 631. Then, move the support ring 631 so that the adjusting bolt 637 moves in the adjusting groove 636. When the support ring 631 rotates to the appropriate position, retighten the adjusting bolt 637 so that it contacts the support ring 631 to fix it. By using the adjusting bolt 637 on the support block 635 to contact the support ring 631 and fix the support ring 631, it is easy to keep the adjusted cleaning rod 61 driving the cleaning head 62 in the adjusted state.

[0047] Reference Figure 3 and Figure 4 The rotating assembly 64 includes a rotating support ring 641 fixed on the traction frame 1. The rotating support ring 641 corresponds to and is rotatably connected to the second support ring 632. A drive motor 642 is fixed at one end of the traction frame 1 near the rotating support ring 641. A drive gear 643 is fixed at the output end of the drive motor 642. Several circumferentially distributed gear grooves are opened on the second support ring 632. The drive gear 643 meshes with the gear grooves on the second support ring 632.

[0048] After the cleaning head 62 on the cleaning rod 61 is pressed against the pipe surface and fixed, the drive motor 642 drives the drive gear 643 to rotate, which in turn drives the second support ring 632. The second support ring 632 rotates under the support of the rotating support ring 641. The second support ring 632 drives the connecting rod 634, which in turn drives the support block 635. The support block 635 drives the first support ring 631, which in turn drives the cleaning rod 61. The cleaning rod 61 then drives the cleaning head 62 to rotate on the pipe surface, allowing the cleaning head 62 to scrape away the water stains remaining on the pipe surface. By using the drive motor 642 to drive the second support ring 632 to rotate under the support of the rotating support ring 641, it is easy for the first support ring 631 to drive the cleaning head 62 on the cleaning rod 61 to rotate and scrape away the water stains on the pipe surface.

[0049] Reference Figure 3 and Figure 4 The auxiliary cleaning mechanism 7 includes a support air ring 71 fixed to one end of the traction frame 1 near the support ring 631. The support air ring 71 has several air inlets 72 on the side near the support frame 2. The air inlets 72 penetrate the traction frame 1. Several circumferentially distributed air blowing pipes 73 are fixed on the inner wall of the support air ring 71. The air blowing pipes 73 are connected to the support air ring 71. An air blowing assembly 74 is provided between the support air ring 71 and the support ring 631.

[0050] While the cleaning head 62 scrapes away water stains on the pipe surface, the rotating support ring 632 on the rotating support ring 641 drives the air blowing assembly 74. The air blowing assembly 74 rotates in the support air duct, allowing external air to enter the support air ring 71 from the air inlet 72 and then blow out from the air blowing duct 73. The air blown out from the air blowing duct 73 is directed towards the surface of the pipe to further clean the water stains remaining on the pipe surface. By using the air blowing assembly 74 to rotate in the support air ring 71, the air is blown from the air blowing duct 73 towards the surface of the pipe, thereby further reducing the possibility of water stains or foreign particles remaining on the pipe surface. At the same time, it can blow away the scraped water, reducing the possibility of water stains coming into contact with the pipe again.

[0051] Reference Figure 3 and Figure 4 The blower assembly 74 includes a rotating ring 742 rotatably connected to a supporting air ring 71. Several circumferentially distributed blower blades 741 are fixed on the rotating ring 742. The blower blades 741 are located inside the supporting air ring 71. A connecting ring 743 is fixed on the rotating ring 742. The connecting ring 743 is fixedly connected to the supporting ring 732.

[0052] While the second support ring 632 rotates on the rotating support ring 641, the second support ring 632 drives the connecting ring 743, the connecting ring 743 drives the rotating ring 742, and the rotating ring 742 drives the fan blade 741 to rotate in the support air duct. When the fan blade 741 rotates, it draws in external air into the support air ring 71 and then blows it out from the air duct 73. By rotating the second support ring 632, the second support ring 632 drives the fan blade 741 on the rotating ring 742 to rotate, so that the second support ring 632 can move the cleaning head 62 while the air duct 73 blows out air to clean water stains on the pipe.

[0053] Reference Figure 3 and Figure 4 The air blower 73 is tilted, with the tilt direction facing the cleaning head 62. By designing the air blower 73 to be tilted, with the tilt direction opposite to the direction of pipe traction, when the air blower 73 blows air, the air blown out will drive the residual water stains towards the cleaning head 62. By designing the air blower 73 to be tilted towards the cleaning head 62, the possibility of water stains entering the traction equipment can be further reduced.

[0054] Working principle: During the production of plastic pipes, the extruder extrudes the plastic into a shape and then sends the pipe into a cooling water tank. After cooling, the pipe is pulled out of the cooling water tank and passes through the traction port of the traction frame 1. According to the diameter of the pipe, the synchronous motor 9 drives the synchronous rod 8. The synchronous rod 8 drives the synchronous gears 10 and 11 at both ends. The synchronous gears 10 and 11 drive the synchronous gear 15 of the corresponding coupling 12 via a chain. The coupling 12 drives the threaded rod 13, which drives the corresponding sliding block 4. The sliding block 4 moves in the sliding rail 5, causing the two lower support frames 2 to move toward or away from the traction port of the traction frame 1. The traction belts 3 on the two lower support frames 2 support the pipe. Then, the hydraulic rod 14 on the traction frame 1 pushes the sliding block 4 of the upper support frame 2 of the pipe, causing the traction belts 3 on the upper support frame 2 to press against the pipe.

[0055] Tighten the adjusting bolt 637 to move it on the support block 635, disengaging it from the support ring 631. Rotate the support ring 631, causing it to drive the cleaning rod 61. The end of the cleaning rod 61 away from the cleaning head 62 moves on the support rail 633, allowing it to rotate on the support ring 631. This causes the cleaning rod 61 to drive the cleaning head 62 to contact the pipe surface. Simultaneously, the pipe is pulled and moved, utilizing the drive... Motor 642 drives drive gear 643 to rotate, which in turn drives support ring 2 632. Support ring 2 632 rotates under the support of rotating support ring 641. Support ring 2 632 drives connecting rod 634, which in turn drives support block 635. Support block 635 drives support ring 1 631, which in turn drives cleaning rod 61. Cleaning rod 61 drives cleaning head 62 to rotate on the surface of the pipe, allowing cleaning head 62 to scrape away residual water stains on the surface of the pipe.

[0056] Simultaneously, the second support ring 632 drives the connecting ring 743, which in turn drives the rotating ring 742. The rotating ring 742 drives the fan blade 741 to rotate within the support air duct. As the fan blade 741 rotates, it draws external air into the support air ring 71 and then blows it out through the air duct 73. The air blown out of the air duct 73 is directed towards the surface of the pipe to further clean the water stains remaining on the surface of the pipe. Subsequently, the pipe is pulled into the traction frame 1 and then sent to the subsequent pipe cutting device for cutting.
