Description

Technical Field

[0001] This invention relates to the field of tension control technology, specifically to a tension control system for take-up and unwinding equipment that improves stability. Background Technology

[0002] Wire winding and unwinding technology is a core part of the production and processing of continuous materials such as cables, metal wires, and films. The main components include winding and unwinding reels, tension frames, and guide wheels. Current wire winding and unwinding equipment is prone to wire vibration and uneven tension when operating at high speeds, which can lead to wire breakage, wire stacking, or equipment vibration. Existing tension frames cannot effectively buffer the tension fluctuations of the wire. Summary of the Invention

[0003] The purpose of this invention is to provide a tension control system for take-up and unwinding equipment that improves stability, so as to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: a tension control system for a take-up and unwinding device with improved stability, comprising a tension frame, wherein a first wheel and a second wheel are disposed on the tension frame, the distance between the first wheel and the second wheel is adjustable, and further comprising: A cable routing assembly is provided on the front side of the tension frame. The cable routing assembly includes a mounting frame with multiple cable routing wheels on the mounting frame. The cable moves along the cable routing wheels in a Z-shaped path to the first wheel body. A guide assembly is mounted on the mounting frame. The guide assembly includes two guide blocks arranged opposite each other. The wire passes between the two guide blocks. The guide blocks can move linearly under the drive of the drive body.

[0005] Furthermore, the mounting bracket includes a first connecting arm and a second connecting arm arranged in parallel, the first connecting arm and the second connecting arm being connected by a third connecting arm, the first connecting arm being located below the second connecting arm, and both the first connecting arm and the second connecting arm being provided with at least two cable guide wheels.

[0006] Furthermore, the guide group is disposed on the first connecting arm and the second connecting arm and is located between two adjacent cable guide wheels.

[0007] Furthermore, the guide assembly includes a mounting plate for accommodating the guide block and the drive body.

[0008] Furthermore, a laser rangefinder is provided on the mounting plate. The laser rangefinder is used to detect the change in distance between itself and the wire. If the change in distance is greater than a set value, the drive body is controlled to move the guide block to adjust the lateral displacement of the wire.

[0009] Furthermore, the tension frame is also provided with a guide assembly, which includes two connecting plates and two guide rollers rotatably connected between the two connecting plates. The guide rollers have two symmetrically arranged inclined sides on their axial cross-section, and the adjacent inclined sides of the two guide rollers are arranged in parallel. The wire passes through the gap between the two guide rollers and contacts the inclined sides on both sides to generate rotation.

[0010] The present invention has the following beneficial effects: This invention extends the contact surface of the wires by using Z-shaped wiring of the wiring group, disperses the tension, makes the tension distribution of the wires more uniform, reduces local stress concentration, and at the same time provides buffering vibration, reducing equipment noise and wear.

[0011] The present invention, through the structure of the guide group, can limit the lateral deviation of the wire, avoid excessive sway, and improve the stability of the wiring.

[0012] This invention uses a guiding component to induce a certain degree of rotation in the wire before it is tensioned, thereby reducing wire tension fluctuations and facilitating its stable arrangement in the first and second wheel bodies. Attached Figure Description

[0013] To more clearly illustrate the technical solutions of the embodiments of the present invention, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0014] Figure 1 This is a schematic diagram of the tension control system for the take-up and unwinding equipment with improved stability, as described in Example 1. Figure 2 for Figure 1 Schematic diagram of the guide group; Figure 3 for Figure 1 A schematic diagram of the bootloader component. Detailed Implementation

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Example 1 like Figures 1-3As shown, the tension control system for improving stability of the take-up and unwinding equipment in this embodiment is used in conjunction with the take-up and unwinding equipment. It is used to take up or unwind the wire by means of a take-up wheel or an unwinding wheel. Specifically, it is integrated into the tension frame 10. This tension frame 10 is provided with a first wheel body 20 and a second wheel body 30. The distance between the first wheel body 20 and the second wheel body 30 is adjustable.

[0017] Specifically, the control system consists of a wiring assembly 40 located on the front side of the tension frame 10, a guide assembly 50 located on the mounting frame, and a guide component 60 located on the tension frame 10.

[0018] The cable routing assembly 40 includes a mounting frame with multiple cable routing wheels 44. The mounting frame includes a first connecting arm 41 and a second connecting arm 42 arranged in parallel. The first connecting arm 41 and the second connecting arm 42 are connected by a third connecting arm 43. The first connecting arm 41 is located below the second connecting arm 42. At least two cable routing wheels 44 are provided on both the first connecting arm 41 and the second connecting arm 42. Thus, the cable 100 moves along the cable routing wheels 44 in a Z-shaped path to the first wheel body 20.

[0019] The guide group 50 is disposed on the first connecting arm 41 and the second connecting arm 42 and located between two adjacent wire guide wheels 44. The guide group 50 includes two guide blocks 51 disposed opposite to each other. The wire 100 passes between the two guide blocks 51. The guide blocks 51 can perform linear motion under the drive of the drive body 52. ​​The guide group 50 also includes a mounting plate 53 that accommodates the guide blocks 51 and the drive body 52. ​​The drive body 52 can be a miniature cylinder or the like, and its output end is connected to the guide block 51, thereby realizing the linear motion of the drive body 52.

[0020] Furthermore, a laser rangefinder sensor 54 is provided on the mounting plate 53. The laser rangefinder sensor 54 is used to detect the distance change between itself and the wire 100. If the distance change is greater than a set value, such as 1.5mm, the drive body 52 is controlled to move the guide block 51 to adjust the lateral displacement of the wire 100. If the distance change is smaller, such as 5cm-4.5cm, the guide block 51 on the same side as the laser rangefinder sensor 54 is controlled to push outward by the difference exceeding the set value to compensate. If the distance change is larger, such as 5cm-5.5cm, the guide block 51 on a different side from the laser rangefinder sensor 54 is controlled to push outward by the difference exceeding the set value to compensate. After the distance change returns to normal, the guide block 51 can be reset to avoid contact with the wire and reduce contact damage.

[0021] Furthermore, the guide assembly 60 includes two connecting plates 62, and two guide rollers 61 are rotatably connected between the two connecting plates 62. The guide rollers 61 have two symmetrically arranged inclined sides 611 on their axial cross-section, and the adjacent inclined sides 611 of the two guide rollers 61 are arranged in parallel. The wire 100 passes through the gap between the two guide rollers 61 and contacts the inclined sides 611 on both sides to generate rotation. That is, the guide rollers 61 have a frustum structure. Thus, when the wire 100 passes between the two guide rollers 61, the guide rollers 61 rotate accordingly. At this time, the wire 100 will rotate due to the inclined sides on both sides, and will undergo a certain degree of self-twisting, eliminating a certain tension fluctuation.

[0022] The preferred embodiments of the present invention disclosed above are merely illustrative of the invention. These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to better understand and utilize the invention. The invention is limited only by the claims and their full scope and equivalents.
