Description

Technical Field

[0001] This utility model relates to the field of traction machine technology, specifically a plastic pipe traction machine. Background Technology

[0002] Plastic pipe traction machines are auxiliary machines in plastic extrusion production lines. They are used to uniformly pull, shape, and transport high-temperature plastic pipes continuously output from the extruder die head to ensure stable pipe dimensions and smooth entry into subsequent cutting or winding processes.

[0003] In existing technologies, traction machines mostly adopt upper and lower tracked or multi-roller structures. Although tracked traction machines have high traction force, changing track specifications is time-consuming, and the large contact area between the track and the pipe easily leaves indentations on the pipe surface. Roller traction machines have a simple structure, but the bottom supporting rollers have a fixed model, and the contact area varies when facing different pipe diameters. To maintain a stable traction force, the clamping pressure of the upper rollers needs to be increased, which can easily lead to indentations and malfunctions. If the contact area between the bottom supporting rollers and the pipe is increased, the entire roller assembly must be replaced with a matching model, which is cumbersome. To address the shortcomings of existing technologies, this utility model provides a plastic pipe traction machine to solve the above problems. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0028] This utility model discloses a plastic pipe traction machine, according to the attached... Figure 1 To be continued Figure 4 As shown, the device includes a frame 1, an electric push rod 2 on the frame 1, a lifting frame 21 at the output end of the electric push rod 2, a motor 22 fixedly connected to the lifting frame 21, and a traction wheel 23 at the output end of the motor 22.

[0029] A support platform 3 is fixedly connected to the equipment frame 1. Several sets of main shafts 5 are rotatably connected to the support platform 3. Multi-wheel brackets 51 are provided on the main shafts 5. Several sets of bottom support wheels 4 for supporting the bottom of the plastic tube are rotatably connected to the multi-wheel brackets 51. A switching unit 6 is provided on the support platform 3 for driving the main shafts 5 and multi-wheel brackets 51 to rotate and thus switching the position of the bottom support wheels 4.

[0030] According to the appendix Figure 3 As shown, the switching unit 6 further includes a worm gear body 61 and a worm shaft body 62. The worm gear body 61 is fixedly connected to the main shaft 5, and the worm shaft body 62 is rotatably connected to the support platform 3 and meshes with the worm gear body 61. By rotating the worm shaft body 62, the worm gear body 61 is driven to rotate using the worm gear transmission principle, thereby causing the main shaft 5 to rotate, realizing the switching of the positions of the multi-wheel support 51 and the bottom support wheel 4.

[0031] According to the appendix Figure 3 As shown, the support platform 3 is further provided with a bearing seat 52 for supporting the spindle 5. The bearing seat 52 can provide stable support for the spindle 5, ensuring the stability of the spindle 5 during rotation and reducing shaking and deviation.

[0032] According to the appendix Figure 3 and attached Figure 4 As shown, furthermore, the worm gear body 61 has several sets of ball grooves 611 on its side, and the bearing 52 is provided with an alignment component 7 for indicating the rotation of the worm gear body 61. The alignment component 7 cooperates with the ball grooves 611 to intuitively indicate the rotation position of the worm gear body 61, making it convenient for the operator to accurately switch the position of the bottom support wheel 4.

[0033] According to the appendix Figure 4 As shown, the alignment assembly 7 further includes a sleeve 71, a spring 72, and a ball joint 73. The sleeve 71 is fixedly connected to the bearing 52, the spring 72 is disposed inside the sleeve 71, and the ball joint 73 is fixedly connected to the end of the spring 72 and passes through the sleeve 71 to fit against the worm gear body 61. The elastic force of the spring 72 keeps the ball joint 73 in contact with the worm gear body 61 at all times. When the worm gear body 61 rotates to the ball groove 611 position, the ball joint 73 enters the ball groove 611 under the action of the spring 72, producing a clear position indication.

[0034] According to the appendix Figure 3 , 4 As shown, the end of the ball head 73 is provided with a ball head that mates with the ball groove 611. The mating design between the ball head and the ball groove 611 makes the alignment more precise and reduces the alignment error caused by uneven contact surfaces.

[0035] According to the appendix Figure 1 To be continued Figure 4 As shown, the plastic pipe traction machine uses an electric push rod 2 to move the lifting frame 21 up and down, thereby adjusting the height of the traction wheel 23 to meet the traction needs of plastic pipes of different specifications.

[0036] According to the appendix Figure 2 To be continued Figure 4 As shown, the switching unit 6 achieves the switching of the position of the bottom support wheel 4 through worm gear transmission, thereby quickly changing the model of the bottom support wheel 4 and quickly adapting to different types of plastic pipe traction work. The worm gear transmission has self-locking properties, which can maintain the stability of the position after switching to the correct position and prevent the bottom support wheel 4 from moving unexpectedly during operation.

[0037] According to the appendix Figure 1 To be continued Figure 4 As shown, it is particularly important to emphasize that the design of the alignment component 7 makes the position switching of the bottom support wheel 4 more accurate and reliable. Operators can quickly determine whether the bottom support wheel 4 is in the correct position by observing the docking of the ball head rod 73 and the ball groove 611.

[0038] The working principle of this plastic pipe traction machine is as follows:

[0039] The electric push rod 2 drives the lifting frame 21 to move up and down, adjusting the height of the traction wheel 23 to a suitable position. When it is necessary to switch the position of the bottom support wheel 4, the worm gear body 62 is rotated, which drives the worm gear body 61 and the main shaft 5 to rotate through the worm gear transmission, thereby causing the multi-wheel bracket 51 to rotate and realizing the switching of the position of the bottom support wheel 4. During the alignment process, the ball head rod 73 is in contact with the worm gear body 61 under the action of the spring 72. When it rotates to the ball groove 611 position, the ball head rod 73 enters the ball groove 611, completing the alignment. The motor 22 drives the traction wheel 23 to rotate, realizing the traction of the plastic pipe under the support of the bottom support wheel 4.

[0040] The operating steps for this plastic pipe traction machine are as follows:

[0041] According to the specifications of the plastic pipe, start the electric push rod 2 and adjust the height of the traction wheel 23.

[0042] Place the plastic tube on the bottom support wheel 4 and make it contact the traction wheel 23.

[0043] Start motor 22, which drives traction wheel 23 to rotate and begin pulling the plastic pipe.

[0044] When it is necessary to change the type of plastic pipe and the bottom support wheel 4, rotate the worm gear body 62, which in turn drives the worm wheel body 61 to rotate. The worm wheel body 61 drives the main shaft 5 and the multi-wheel bracket 51 to rotate, thereby quickly switching the model of the bottom support wheel 4 to adapt to the plastic pipe.

[0045] Observe the alignment of the ball head 73 and the ball groove 611 until alignment is completed.

[0046] Restart motor 22 to drive traction wheel 23 to rotate and begin pulling the plastic pipe.

[0047] The beneficial effects of this plastic pipe traction machine are as follows:

[0048] The electric push rod 2 and the lifting frame 21 work together to quickly adjust the distance between the traction wheel 23 and the bottom support wheel 4, adapting to different specifications of plastic pipes; the switching unit 6 enables quick switching of the position of the bottom support wheel 4, improving the adaptability and working efficiency of the equipment; the worm gear meshing provides a self-locking function, ensuring the stability of the bottom support wheel 4 after position adjustment; and the ball joint 73 and the ball groove 611 work together to achieve precise positioning of the rotation position, improving the reliability of the equipment.
