Description

Technical Field

[0001] This utility model relates to the technical field of traction devices for polyethylene pipe production, and in particular to a traction device for polyethylene pipe production. Background Technology

[0002] In the continuous production of polyethylene pipes, the conveying and orientation of the formed pipes are crucial steps affecting the efficiency of subsequent processing. In traditional production processes, extruded pipes are prone to random rolling deviations after cooling, leading to inconsistent conveying angles. This necessitates frequent manual adjustments to ensure alignment. However, manual intervention is not only inefficient and labor-intensive but also difficult to adapt to the pace of high-speed production lines. Delayed adjustments can easily cause pipe accumulation or misalignment, severely impacting the continuity of automated production. Furthermore, existing traction devices often employ fixed guide structures, failing to dynamically correct pipe angle deviations, resulting in a higher defect rate.

[0003] To address this issue, we propose a traction device for polyethylene pipe production. Utility Model Content

[0004] The purpose of this invention is to provide a traction device for polyethylene pipe production. When using this device, the coordinated action of an infrared detector and an angle adjustment mechanism enables automated detection and dynamic correction of the polyethylene pipe's conveying posture. On one hand, the infrared detector accurately identifies pipe angle deviations and triggers classified flow guidance, avoiding manual intervention. On the other hand, the rotating and lifting design of the adjustment disc combined with the electric push rod allows for rapid correction of the pipe angle within a 90° range, ensuring consistent output posture. Simultaneously, the traction adjustment platform forms a closed-loop adjustment process through the linkage control of the limit wall, push block, and turntable. The timing coordination between the electric telescopic rod and the cylinder platform enables rapid interception, directional pushing, and resetting of defective pipes. The overall structure is compact and responsive, significantly improving conveying efficiency and product qualification rate, thus solving the problems mentioned in the background art.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 A polyethylene pipe production traction device includes a conveyor belt 1. The pipe is first conveyed by the conveyor belt 1 to the traction adjustment table 2. The limiting wall 3 at the front end of the traction adjustment table 2 initially limits the pipe. Its side wall opening and the push block 9 form a guide channel. When the pipe enters the traction adjustment table 2, the infrared detector 5 scans the outline of the pipe through multiple sets of transverse infrared beams: if the pipe axis is parallel to the conveying direction, the infrared beam is blocked in its entirety, the opening 4 remains open, and the pipe directly enters the next process via the conveyor table 15; if the pipe is tilted, causing part of the infrared beam to be unblocked, the infrared detector 5 immediately triggers the electric control shaft to close the opening 4, and at the same time starts the electric telescopic rod 6 to push the limiting plate 7 to block the opening 4, preventing the pipe from moving forward.

[0025] Subsequently, the cylinder platform 8 drives the push block 9 to push the inclined pipe into the opening of the limiting wall 3, so that it slides into the semi-circular groove of the adjusting plate 12. The electric rotating shaft 11 at the bottom of the adjusting plate 12 is linked with the turntable 10. When the pipe falls into the semi-circular groove, the pressure sensor at the top of the electric push rod 13 senses the pressure signal and triggers the electric rotating shaft 11 to drive the turntable 10 to rotate 90°. During this process, the electric push rod 13 rises synchronously with the turntable 10 until the pipe is lifted to a vertical position and then leaves the semi-circular groove, sliding down the discharge port 14 to the conveying platform 15. When the electric push rod 13 detects that the pressure has disappeared, the electric rotating shaft 11 reverses and resets. At the same time, the limiting plate 7 retracts, the push block 9 returns to its original position, and the opening and closing port 4 reopens, and the system enters the next cycle.

[0026] The working principle of this utility model is as follows: As shown in the figure, it includes a conveyor belt 1. The pipe is first conveyed by the conveyor belt 1 to the traction adjustment table 2. The limiting wall 3 at the front end of the traction adjustment table 2 initially limits the pipe. Its side wall opening and the push block 9 form a guide channel. When the pipe enters the traction adjustment table 2, the infrared detector 5 scans the outline of the pipe through multiple sets of transverse infrared beams: If the pipe axis is parallel to the conveying direction, the infrared beam is blocked in its entirety, the opening 4 remains open, and the pipe directly enters the next process through the conveyor table 15; If the pipe is tilted, causing part of the infrared beam to be unblocked, the infrared detector 5 immediately triggers the electric control shaft to close the opening 4, and at the same time starts the electric telescopic rod 6 to push the limiting plate 7 to block the opening 4, preventing the pipe from moving forward.

[0027] Subsequently, the cylinder platform 8 drives the push block 9 to push the inclined pipe into the opening of the limiting wall 3, so that it slides into the semi-circular groove of the adjusting plate 12. The electric rotating shaft 11 at the bottom of the adjusting plate 12 is linked with the turntable 10. When the pipe falls into the semi-circular groove, the pressure sensor at the top of the electric push rod 13 senses the pressure signal and triggers the electric rotating shaft 11 to drive the turntable 10 to rotate 90°. During this process, the electric push rod 13 rises synchronously with the turntable 10 until the pipe is lifted to a vertical position and then leaves the semi-circular groove, sliding down the discharge port 14 to the conveying platform 15. When the electric push rod 13 detects that the pressure has disappeared, the electric rotating shaft 11 reverses and resets. At the same time, the limiting plate 7 retracts, the push block 9 returns to its original position, and the opening and closing port 4 reopens, and the system enters the next cycle.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity.
