Description

Technical Field

[0001] This utility model relates to the technical field of tension adjustment components, specifically a tension adjustment component for a chemical fiber winding machine. Background Technology

[0002] A chemical fiber winding machine is a key piece of equipment specifically used for the production of chemical fibers. It is mainly used to wind spun fiber bundles into packages of a specific shape. Its core function includes tension control. By using tension adjustment components, it can ensure that the fibers maintain constant tension during the winding process, ensuring that the package is tight and structurally stable.

[0003] In existing tension controllers and solutions for winding machines, the tension adjustment component of the chemical fiber winding machine typically consists of a rotating support rod, a guide roller at the end away from the support rod, and a spring. One end of the spring is fixed to a small steel rod extending from the vertical plate, and the other end is fixed to the surface of the rotating support rod. The spring force causes the support rod to rotate in response to changes in tension. However, in actual use, the combination of the support rod and spring is easily affected by inertia during rotation, making it prone to vibration. Due to the high moment of inertia of the support rod and guide roller, dynamic response is delayed. When the fiber tension changes abruptly, the support rod cannot rotate quickly, easily leading to tension loss of control. Therefore, it is necessary to improve the tension adjustment component of the chemical fiber winding machine to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a tension adjustment component for a chemical fiber winding machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tension adjustment component for a chemical fiber winding machine, comprising a vertical plate, a limiting rod fixedly installed on the front of the vertical plate, a limiting guide roller rotatably installed on the outside of the limiting rod, and a counterweight tension adjustment mechanism provided on the front of the vertical plate.

[0006] Preferably, the counterweight tension adjustment mechanism includes a rotating limit seat, which is fixedly installed on the front of the upright plate. A rotating column is rotatably installed inside the rotating limit seat, and a support rod is fixedly installed inside the rotating column. A limit guide roller is fixedly installed at the end of the support rod away from the rotating limit seat, and a connecting arm is rotatably installed at the end of the support rod near the rotating limit seat. A counterweight is rotatably installed at the end of the connecting arm away from the support rod. A limit shell and a fixed limit post are fixedly installed on the front of the upright plate. A perforated sleeve is fixedly installed on the outside of the support rod, and a spring is hung inside the perforated sleeve. A baffle is slidably installed on the outside of the fixed limit post, and a bolt is threaded inside the fixed limit post.

[0007] Preferably, the limiting shell has a sliding groove inside, and the counterweight is slidably installed inside the sliding groove inside the limiting shell.

[0008] Preferably, the end of the spring away from the perforated sleeve is provided with a collar, and the collar provided at the end of the spring away from the perforated sleeve is sleeved on the outside of the fixed limiting post, and the collar is provided on the inside of the baffle and the bolt.

[0009] Preferably, the counterweight has a limiting shaft on its front side, and the limiting shaft on the front side of the counterweight is rotatably mounted on the end of the connecting arm away from the support rod.

[0010] Preferably, the perforated sleeve has a hole inside, and the top end of the spring is hung inside the hole inside the perforated sleeve.

[0011] Compared with the prior art, this utility model provides a tension adjustment component for a chemical fiber winding machine, which has the following beneficial effects:

[0012] The tension adjustment component of this chemical fiber winding machine, through its counterweight-type tension adjustment mechanism, utilizes a connecting arm and a counterweight located at the left end of the support rod. When the support rod rotates, the counterweight is subjected to centrifugal force and moves within the limiting shell. Through the combination of levers and the counterweight, the rotational inertia of the support rod is changed. During high-speed winding, the counterweight increases the rotational inertia to suppress support rod vibration, while at low speeds, it reduces the inertia to improve response speed. Through the adaptive adjustment of the counterweight, it can counteract the inertial impact caused by sudden changes in fiber tension and avoid tension loss of control. Attached Figure Description

[0019] 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.

[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example

[0021] Please see Figure 1-4 This utility model provides a technical solution: a tension adjustment component for a chemical fiber winding machine, including a vertical plate 1, a limiting rod 3 fixedly installed on the front of the vertical plate 1, a limiting guide roller 4 rotatably installed on the outside of the limiting rod 3, and a counterweight tension adjustment mechanism 2 provided on the front of the vertical plate 1.

[0022] Furthermore, the counterweight tension adjustment mechanism 2 includes a rotation limit seat 21, which is fixedly installed on the front of the upright plate 1. A rotating column 22 is rotatably installed inside the rotation limit seat 21, and a support rod 23 is fixedly installed inside the rotating column 22. A limit guide roller 24 is fixedly installed at the end of the support rod 23 away from the rotation limit seat 21, and a connecting arm 25 is rotatably installed at the end of the support rod 23 near the rotation limit seat 21. A counterweight block 26 is rotatably installed at the end of the connecting arm 25 away from the support rod 23. A limit shell 2 is fixedly installed on the front of the upright plate 1. 7. A perforated sleeve 28 is fixedly installed on the outside of the fixed limiting post 210 and the support rod 23. A spring 29 is hooked inside the perforated sleeve 28. A baffle 211 is slidably installed on the outside of the fixed limiting post 210. A bolt 212 is threaded inside the fixed limiting post 210. Through the set counterweight tension adjustment mechanism 2, the counterweight block 26 and the spring 29 work together to accurately balance the rotational inertia of the support rod 23. When the fiber tension changes suddenly, the counterweight block 26 moves quickly through the slide groove to generate a reverse torque, suppressing the vibration of the support rod and reducing the dynamic response delay.

[0023] Furthermore, a groove is provided inside the limiting shell 27, and the counterweight 26 is slidably installed inside the groove provided inside the limiting shell 27. The groove forcibly guides the movement path of the counterweight 26, reduces the lateral vibration caused by inertial impact, avoids the amplitude accumulation caused by the lack of restraint in the traditional pure spring structure, and reduces the risk of tension runaway.

[0024] Furthermore, a collar is provided at the end of the spring 29 away from the perforated sleeve 28, and the collar at the end of the spring 29 away from the perforated sleeve 28 is sleeved on the outside of the fixed limiting post 210. The collar is located inside the baffle 211 and the bolt 212. The collar cooperates with the baffle 211 and the bolt 212 to limit the spring 29 and prevent the spring 29 from displacing and falling off.

[0025] Furthermore, a limiting shaft is provided on the front of the counterweight 26, and the limiting shaft on the front of the counterweight 26 is rotatably mounted on the end of the connecting arm 25 away from the support rod 23. The hinged design of the limiting shaft allows the rotational inertia of the counterweight 26 to adapt to the angle of the support rod 23, dynamically matching the tension adjustment requirements and solving the problem of response hysteresis in high inertia systems.

[0026] Furthermore, the perforated sleeve 28 has a hole inside, and the top of the spring 29 is hung inside the hole inside the perforated sleeve 28. The perforated sleeve 28 constrains the spring 29, eliminating the interference of the spring's lateral swing on the support rod 23 when traditional single-point suspension is used, and ensuring the linear accuracy of tension control.

[0027] In actual operation, when this device is used, the counterweight 26 and the internal groove of the limiting shell 27 cooperate to generate a reverse inertial torque when the fiber tension changes abruptly. This directly counteracts the shaking caused by the high rotational inertia of the support rod 23. The variable stiffness characteristic of the spring 29, combined with the adaptive rotational inertia adjustment of the counterweight 26, automatically compensates for the tension attenuation when the roll diameter increases. At the same time, the hinge of the limiting shaft eliminates the lateral swing interference of the support rod 23. This allows the tension to be adaptively adjusted when the winding machine is producing chemical fiber, and the support rod 23 will not shake or the tension will not get out of control.

[0028] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
