Detailed implementation manners

[0026] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Embodiment 1:

[0028] Please refer to Figure 1 - Figure 5As shown in the figure, a double six-claw tractor for plastic pipes with a certain span includes a frame 1. At both the left and right ends of the frame 1, radial guiding rings 3 are fixedly installed through structural support frames 2. The radial guiding rings 3 can initially limit and guide the pipes, enabling the pipes to accurately enter from one side of the frame 1 and exit from the other side. Inside the left and right sides of the frame 1, a short six-claw traction device and a long six-claw traction device are respectively arranged. Both the short six-claw traction device and the long six-claw traction device include a first chute guide rail mechanism 4, a second chute guide rail mechanism 5, a traction mechanism 6, a driving mechanism 7, and a cleaning mechanism 8. Three groups of the first chute guide rail mechanisms 4 are arranged in a circular array and distributed in the upper half of the radial guiding ring 3. Three groups of the second chute guide rail mechanisms 5 are arranged in a circular array and are respectively in the lower half of the radial guiding ring 3. Six groups of the traction mechanisms 6 and the cleaning mechanisms 8 are arranged in an array with the center of the radial guiding ring 3 as the center of the circle. Two groups of the driving mechanisms 7 are arranged at the lower ends of the left and right sides of the frame 1 respectively;

[0029] It should be noted that a traction claw is composed of a set of the first chute guide rail mechanism 4, the second chute guide rail mechanism 5, the traction mechanism 6, the driving mechanism 7, and the cleaning mechanism 8. Six annularly distributed traction claws form the short six-claw traction device or the long six-claw traction device. After the pipe enters the inside of the frame 1, the short six-claw traction device clamps it through six traction claws and then can convey it to the right. After the right end part of the pipe enters the inside of the long six-claw traction device, the long six-claw traction device first clamps it. After the short six-claw traction device releases the pipe, the long six-claw traction device then conveys it to the right. The six annularly distributed traction claws make the regulation and control of this tractor flexible, effectively avoiding the disadvantage of suspending production due to frequently replacing the traction pipe with multiple diameters.

[0030] The first chute guide rail mechanism 4 includes a cylinder 401. Two cylinders 401 are symmetrically arranged and are respectively arranged on the inner walls of the left and right sides of the upper half of the frame 1. The telescopic ends of the two cylinders 401 are both provided with a first guide rail sliding block 402. The other ends of the two first guide rail sliding blocks 402 are both slidably connected to a first fixed guide rail 403. The two first fixed guide rails 403 are respectively arranged on the inner walls of the left and right sides of the upper half of the frame 1. Among them, the moving distance of the first guide rail sliding block 402 has a limit to prevent the whole of the first guide rail sliding block 402 from moving out of the first fixed guide rail 403, which affects the moving effect and enables the first guide rail sliding block 402 to stably move horizontally in a preset direction;

[0031] The slideway guide rail mechanism 2 5 includes a reducer 1 501, and two reducers 1 501 are symmetrically arranged and respectively arranged inside the left and right sides of the lower half of the frame 1. The output ends of the two reducers 1 501 are both provided with lead screws 502, and the circumferential surfaces of the two lead screws 502 are both threadedly connected with guide rail sliding blocks 2 503. One side of the two guide rail sliding blocks 2 503 is slidably connected with fixed guide rails 2 504. The two fixed guide rails 2 504 are respectively arranged on the inner walls of the left and right sides of the lower half of the frame 1. The setting of the fixed guide rails 2 504 can limit the moving distance of the guide rail sliding block 2 503, and prevent the guide rail sliding block 2 503 from moving out of the lead screw 502 as a whole, so that when the lead screw 502 rotates, the guide rail sliding block 2 503 can move smoothly on the lead screw 502;

[0032] The traction mechanism 6 includes a traction frame 601, the left and right ends of the traction frame 601 located at the upper half of the frame 1 are connected to the inside of the guide rail sliding block 402, and the left and right ends of the traction frame 601 located at the lower half of the frame 1 are connected to the inside of the guide rail sliding block 503. A driving motor 1 602 is arranged on the left outer surface of the traction frame 601, and the power output end of the driving motor 1 602 is connected to the reducer 2 603 through a coupling, and the output end of the reducer 2 603 is connected to the rotating shaft 604, and the circumferential surface of the rotating shaft 604 is connected to the traction belt 606 through a driving roller 605. The outer surface of the traction belt 606 is fixed with a traction gasket 607 by bolts. The setting of the bolts makes it easy for the staff to disassemble any traction gasket 607 by the bolts, so that when part of the traction gasket 607 is damaged or the anti-skid pattern is worn, a new traction gasket 607 can be replaced. , so that the traction effect of this traction claw can always be in an excellent state, and the surface of the traction pad 607 is provided with anti-skid patterns. When the traction pad 607 with anti-skid patterns can fit with the surface of the pipe, the friction force is increased, and then when the traction belt 606 drives the traction pad 607 to rotate, the pipe is smoothly pushed to the right. Support guide rollers 608 are rotatably installed inside the upper and lower ends of the traction frame 601, and the support guide rollers 608 are respectively abutted against the inner walls of the upper and lower sides of the traction belt 606. The setting of the support guide rollers 608 can support the middle part of the traction belt 606, so that when the middle part of the traction belt 606 abuts against the clamping pipe, the middle part of the traction belt 606 will not be concave, thereby improving the clamping and traction effect of the traction pad 607. At the same time, the support guide rollers 608 will not generate large friction with the inner surface of the traction belt 606, thereby reducing the loss of the traction belt 606 and improving the service life.

[0033] The driving mechanism 7 includes a driving motor 2 701, and two driving motors 2 701 are provided and respectively installed in the middle of the lower ends of the left and right sides of the frame 1. The power output end of the driving motor 2 701 is connected to the reducer 3 702 through a coupling transmission. The output end of the reducer 3 702 is provided with a rotating rod 1 703, and the rotating rod 1 703 penetrates the reducer 3 702 and extends to the left and right sides of the reducer 3 702. The left and right ends of the rotating rod 1 703 are respectively connected to the input ends of the middle reducer 1 501 on the left and right sides, and a spur gear 1 704 is provided at the connecting end. The front and rear sides of the two spur gears 1 704 are The spur gear 2 706 is connected to the intermediate reducer 1 501 through the toothed chain 705. The four spur gears 2 706 are respectively arranged on the input ends of the four reducers 1 501 above the intermediate reducer 1 501. The arrangement of the driving mechanism 7 can make the six reducers 1 501 work synchronously when the driving motor 2 701 is started, and then the six guide rail sliding blocks 2 503 drive the three traction frames 601 to move the same distance in the direction of the center of the radial guide ring 3, so that the traction gaskets 607 inside the three traction frames 601 are respectively in contact with the outer surface in the middle of the lower end, the outer surface in front of the lower end, and the outer surface behind the lower end of the pipe;

[0034] It should be noted that the internal structures of the short six-claw traction device and the long six-claw traction device are roughly the same. The only thing about the internal structure of the long six-claw traction device is that the traction belt 606 and the rotating rod 703 are longer than those of the short six-claw traction device. Correspondingly, there are more traction gaskets 607 arranged on the traction belt 606. Other structures are the same, so that the operating steps of the short six-claw traction device and the long six-claw traction device are the same when clamping the limiting pipe.

[0035] Embodiment 2:

[0036] Please refer to Figure 3 and Figure 5As shown in the figure, the cleaning mechanism 8 includes an installation box 801, and the installation box 801 is arranged on the left surface of the traction frame 601. A second rotating rod 802 is rotatably installed inside the installation box 801. A cleaning brush 803 is arranged on the circumferential surface of the second rotating rod 802, and the lower end of the cleaning brush 803 abuts against the surface of the traction gasket 607. The cleaning brush 803 can be a brush made of nylon material (but not limited to this), so that when the cleaning brush 803 removes the dust on the surface of the traction gasket 607, it is not easy to damage the traction gasket 607, and the service life of the traction gasket 607 is improved. A third spur gear 804 is arranged on the circumferential surface at the rear side of the second rotating rod 802. The lower end of the third spur gear 804 is meshed and connected with a sliding plate 806 through a first toothed plate 807. The lower end of the sliding plate 806 is respectively meshed and connected with a first intermittent gear 809 and a second intermittent gear 814 through a second toothed plate 811. The first intermittent gear 809 is arranged on the circumferential surface of the rotating shaft 604. The second intermittent gear 814 is rotatably installed inside the installation box 801 through a third rotating rod 812. A fifth spur gear 810 is arranged on the circumferential surface of the third rotating rod 812, and the fifth spur gear 810 is located in front of the second intermittent gear 814. A fourth spur gear 808 is meshed and connected to the left side of the fifth spur gear 810, and the fourth spur gear 808 is arranged on the circumferential surface of the rotating shaft 604. An exhaust pipe 813 is arranged inside the upper end of the installation box 801. The exhaust pipe 813 penetrates through the installation box 801 and is connected with a dust suction nozzle, and the dust suction nozzle is arranged above the cleaning brush 803. The other end of the exhaust pipe 813 is connected with an air pump, so that when the air pump works, the dust and impurities cleaned can be sucked away through the exhaust pipe 813 and the dust suction nozzle, avoiding secondary adhesion of dust;

[0037] It should be noted that the teeth on the surfaces of the first intermittent gear 809 and the second intermittent gear 814 are set in a complementary state, that is, when the first intermittent gear 809 drives the sliding plate 806 to move horizontally through the first toothed plate 807, the teeth of the second intermittent gear 814 will not be meshed with the first toothed plate 807. Similarly, when the teeth of the first intermittent gear 809 are not meshed with the first toothed plate 807, the second intermittent gear 814 will drive the sliding plate 806 to move horizontally in the reverse direction through the first toothed plate 807, realizing the left and right reciprocating movement of the sliding plate 806. Then, the cleaning brush 803 is driven to swing left and right through the third spur gear 804 and the second rotating rod 802, quickly cleaning the surface of the traction gasket 607 and sweeping down the dust and impurities.

[0038] Inside the installation box 801, there is a fixed rod 805. The sliding plate 806 is slidably installed on the surface of the fixed rod 805. The setting of the fixed rod 805 can limit the installation of the sliding plate 806. Moreover, a cross plate is provided on the surface of the fixed rod 805, and a cross groove matching the cross plate is opened inside the sliding plate 806. When the sliding plate 806 is installed on the fixed rod 805, it will not rotate, and then it can stably move horizontally on the fixed rod 805. There are two second toothed plates 811. The left second toothed plate 811 is arranged at the left rear end of the sliding plate 806, and the right second toothed plate 811 is arranged at the right front end of the sliding plate 806, so that the intermittent gear one 809 and the intermittent gear two 814 are not on the same horizontal plane. Then, when the intermittent gear one 809 rotates, it will not contact the intermittent gear two 814 and affect the rotation.

[0039] When the present invention is in use, the pipe passes through the radial guiding ring 3 on the left side and enters the inside of the frame 1. Then, the short six-claw traction device is started. The three groups of six cylinders 401 above the short six-claw traction device work together, and at the same time, the second driving motor 701 works. The six cylinders 401 work to drive the six guide rail sliding blocks one 402 to move, and then drive the three traction frames 601 above in the short six-claw traction device to move towards the center of the radial guiding ring 3. The second driving motor 701 works to drive the third reducer 702 and the first rotating rod 703 to rotate. The first rotating rod 703 rotates to drive the first spur gear 704 and the first reducer 501 in the middle of the lower end to rotate. The first spur gear 704 rotates to drive the front and rear second spur gears 706 and the first reducer 501 to rotate through the tooth chain 705. Then, the first reducers 501 in the middle of the lower end, in front of the lower end, and at the rear of the lower end work together, so that the six first reducers 501 drive the six lead screws 502 to rotate, and then drive the guide rail sliding blocks two 503 to move, so that the guide rail sliding blocks two 503 drive the three traction frames 601 below in the short six-claw traction device to move towards the center of the radial guiding ring 3. Furthermore, the traction gaskets 607 inside the six traction frames 601 abut against the outer surface of the pipe and clamp it inside the frame 1;

[0040] Start the first driving motor 602. The first driving motor 602 drives the second reducer 603, the rotating shaft 604 and the driving roller 605 to rotate. The rotation of the driving roller 605 drives the traction belt 606 and the traction gasket 607 to rotate counterclockwise, so that the traction gasket 607 pushes the pipe to the right. At the same time, the rotation of the rotating shaft 604 also drives the fourth spur gear 808 and the first intermittent gear 809 to rotate. The rotation of the fourth spur gear 808 drives the fifth spur gear 810, the third rotating rod 812 and the second intermittent gear 814 to rotate. When the teeth of the first intermittent gear 809 engage with the second toothed plate 811 below the sliding plate 806, it can drive the sliding plate 806 to move to the left, so that the sliding plate 806 drives the third spur gear 804, the second rotating rod 802 and the cleaning brush 803 to rotate slightly counterclockwise through the first toothed plate 807. Then, when the teeth of the first intermittent gear 809 do not engage with the second toothed plate 811, the teeth of the second intermittent gear 814 will engage with its corresponding second toothed plate 811, thereby driving the sliding plate 806 to move to the right, so that the sliding plate 806 drives the third spur gear 804, the second rotating rod 802 and the cleaning brush 803 to rotate slightly clockwise to reset. Furthermore, the cleaning brush 803 can swing back and forth on the traction gasket 607 to clean the surface of the traction gasket 607, and the dust cleaned is sucked away through the dust extraction pipe 813 to avoid secondary adhesion of dust;

[0041] When the pipe is moved to the right so that its right end moves into the right side inside the frame 1 and part of the pipe is located inside the left side of the long six-claw traction device, the long six-claw traction device is started at this time. Since the long six-claw traction device and the short six-claw traction device have roughly the same structure, through the same above operations, the mechanisms inside the long six-claw traction device work, and the long six-claw traction device can clamp and limit the pipe. Then, when the long six-claw traction device works, it can continue to convey the pipe to the right.

Obviously, according to the content of this specification, many modifications and changes can be made.
