Description

Technical Field

[0001] This utility model relates to the field of copper rod production technology, specifically to an anti-winding copper rod production tension adjustment frame. Background Technology

[0002] In the production of copper rods, precise tension control plays a decisive role in product quality. Appropriate tension ensures that the copper rod maintains stable shape and dimensional accuracy during stretching, rolling, and other processing stages, effectively reducing stress concentration within the rod and lowering the probability of defects such as cracks and deformation, thereby improving the overall quality and performance of the copper rod.

[0003] However, traditional tension adjustment frames for copper rod production have revealed numerous problems in practical applications. Existing tension adjustment frames have limitations in their structural design, making it difficult to provide precise and flexible tension adjustment for copper rods of different specifications and materials. When faced with the production needs of multiple copper rod models, frequent replacement of equipment parts is not only time-consuming and labor-intensive but also significantly impacts production efficiency and increases production costs. For example, when processing copper rods with significant diameter differences, traditional adjustment frames cannot quickly adapt and adjust to the optimal tension state, leading to uneven stretching and surface scratches during processing, severely affecting product quality.

[0004] Therefore, the applicant proposes an anti-winding copper rod production tension adjustment frame. Utility Model Content

[0005] The purpose of this invention is to provide an anti-winding tension adjustment frame for copper rod production, solving the following technical problems: Existing tension adjustment frames have limitations in structural design, making it difficult to provide precise and flexible tension adjustment for copper rods of different specifications and materials. When facing the production needs of multiple copper rod models, frequent replacement of equipment parts is not only time-consuming and labor-intensive, but also greatly affects production efficiency and increases production costs. For example, when processing copper rods with large diameter differences, traditional adjustment frames cannot quickly adapt and adjust to the optimal tension state, resulting in uneven stretching and surface scratches on the copper rods during processing, seriously affecting product quality.

[0006] The purpose of this utility model can be achieved through the following technical solution: an anti-winding copper rod production tension adjustment frame, including a base, an adjustment bracket slidably disposed on the upper end of the base, and a tension adjustment component disposed between the inner sidewalls of the adjustment bracket; The tension adjustment assembly includes a first adjustment roller disposed between the side walls of the adjustment bracket. The first adjustment roller has symmetrically rotatably mounted shafts at both ends. A sliding block is fixedly mounted at one end of each shaft. The sliding block is slidably disposed within a groove on the inner side wall of the adjustment bracket. Adjustment screws are threaded to both sides of the upper end of the adjustment bracket. A fixing sleeve is rotatably mounted at the lower end of each adjustment screw. A fixing rod is slidably fitted inside the fixing sleeve. A limit plate is fixedly mounted at one end of the fixing rod. A spring is fitted onto the surface of the fixing rod and fixed between the limit plate and the fixing sleeve. The lower end of the fixing rod is fixedly connected to the sliding block. A second adjustment roller is disposed below the first adjustment roller and rotatably connected to the inner side wall of the adjustment bracket.

[0007] As a further embodiment of this utility model: a mounting box is fixedly provided at the top of the base, and a winding roller assembly is provided inside the mounting box. The winding roller assembly includes a winding roller disposed between the inner side walls of the mounting box. Flanges are fixedly provided at both ends of the winding roller. A servo motor is provided on one side of the mounting box. The output shaft of the servo motor passes through the side wall of the mounting box and is fixedly connected to one of the flanges. The outer side of the other flange is rotatably connected to the inner side wall of the mounting box through a bearing.

[0008] As a further embodiment of this utility model: a support rod is slidably provided on the upper end of the base, a rotating rod is rotatably provided on the upper end of the support rod, and a guide ring is fixedly provided on the upper end of the rotating rod.

[0009] As a further embodiment of this utility model: the base is provided with a driving assembly, the driving assembly includes a connecting rod slidably disposed inside the base, the two ends of the connecting rod are fixedly provided with positioning bushings, the two positioning bushings are slidably sleeved with positioning rods, and the two positioning rods are connected to the inner sidewall of the base.

[0010] As a further embodiment of this utility model: the surfaces of both the first adjusting roller and the second adjusting roller are provided with diamond-shaped patterns.

[0011] As a further embodiment of this invention, a sponge pad is provided on the inner sidewall of the guide ring.

[0012] As a further embodiment of this utility model, multiple adjustable feet are provided at the four corners of the bottom of the base.

[0013] As a further embodiment of this utility model: the upper end of the support rod is provided with a slot, and the lower end of the rotating rod is rotatably sleeved in the slot.

[0014] The beneficial effects of this utility model are: (1) This utility model uses an adjusting screw to drive the fixed sleeve to move up and down. The fixed sleeve drives the first adjusting roller to move through the slider, thereby adjusting the distance between the two adjusting rollers to meet the basic tension requirements of copper rods of different specifications when winding. During the tension adjustment process, when the winding speed of the copper rod fluctuates, the material is uneven, or the diameter changes slightly, the spring maintains moderate elastic deformation while maintaining constant tension, which can effectively avoid equipment damage or copper strip breakage caused by rigid collision, and significantly extend the service life of the equipment.

[0015] (2) This utility model uses a drive assembly to drive the adjustment bracket to reciprocate. The copper rod enters from one end of the guide ring, is guided by two sets of adjustment rollers, and then winds around the surface of the winding roller. The reciprocating movement of the adjustment bracket can make the copper rod evenly wind around the surface of the winding roller, avoiding the formation of winding blind areas at both ends, and effectively improving the space utilization of the winding roller. This structural design can prevent the copper rod from being squeezed and deformed due to local accumulation, ensuring that the wound copper rod is tight and regular, providing high-quality coil material for subsequent handling, storage and deep processing, and significantly improving production efficiency and product quality.

Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0022] In the field of copper rod production technology, the anti-winding and pressure regulation problems of tension adjustment brackets in copper rod production not only affect the stability and efficiency of copper rod winding, but also cause reduced operability and significant limitations in the use of adjustment brackets. This utility model develops an anti-winding tension adjustment bracket for copper rod production, which achieves uniform winding of copper rods through a series of innovative designs, avoiding the occurrence of winding. Its specific implementation is as follows: Example 1: As Figure 1 As shown, an anti-winding copper rod production tension adjustment frame includes a base 1, with a mounting box 2 fixedly mounted on the top of the base 1. A winding roller assembly 3 is installed inside the mounting box 2. The winding roller assembly 3 is used to uniformly wind the straightened copper rod from the adjustment bracket 5, facilitating subsequent forklift handling, warehousing management, and centralized transportation and processing. Simultaneously, the winding roller assembly 3 provides uniform and stable support force to the copper rod during the winding process, effectively avoiding secondary bending deformation caused by factors such as suspension and swaying after straightening, thereby improving processing efficiency and accuracy. The winding roller assembly 3 includes a winding roller 31 disposed between the inner side walls of the mounting box 2. Flanges 32 are fixedly mounted at both ends of the winding roller 31. A servo motor 33 is mounted on one side of the mounting box 2. The output shaft of the servo motor 33 passes through the side wall of the mounting box 2 and is fixedly connected to one of the flanges 32. The outer side of the other flange 32 is rotatably connected to the inner side wall of the mounting box 2 via a bearing. The first servo motor 33 drives the winding roller 31 to rotate, so that the straightened copper rod can be slowly wound onto the winding roller 31.

[0023] The base 1 houses a drive assembly 4, which enables the reciprocating movement of the adjusting bracket 5. The drive assembly 4 drives the adjusting bracket 5 to reciprocate at a constant frequency, causing the copper rod to gradually cover the entire surface of the winding roller 31 in a spiral trajectory. This dynamic adjustment mechanism completely changes the drawback of traditional fixed winding methods, where the copper rod is concentrated in the middle of the winding roller 31 due to its fixed position, resulting in winding blind spots at both ends. By evenly distributing the winding area, not only is the space utilization of the winding roller 31 improved, but the deformation of the copper rod caused by excessive local accumulation is also effectively avoided. This ensures that the copper rod is wound tightly and neatly, providing higher quality and more regular copper rod coils for subsequent handling, storage, and deep processing, significantly improving production efficiency and product quality.

[0024] An adjusting bracket 5 is slidably mounted on the upper end of the base 1. The adjusting bracket 5 is connected to the drive assembly 4. A tension adjusting assembly 6 is provided between the inner side walls of the adjusting bracket 5. The tension adjusting assembly 6 is used to adjust the pressure of the winding copper rod. In actual production, due to the significant differences in the diameter of the copper rod, ranging from the very thin 8mm to the thicker 40mm, the tension adjusting assembly 6 is required during production to flexibly adjust the pressure value according to the different diameters of the copper rod, ensuring that the copper strip maintains a constant tension during the production process. This ensures that the copper strip is not subjected to excessive mechanical stress during the production process, thus avoiding deformation or breakage of the copper strip.

[0025] The tension adjustment assembly 6 includes a first adjustment roller 61 disposed between the side walls of the adjustment bracket 5. The two ends of the first adjustment roller 61 are symmetrically rotatably provided with a rotating shaft 62. A sliding block 63 is fixedly provided at one end of the rotating shaft 62. The inner side wall of the adjustment bracket 5 is provided with a sliding groove at both ends. The sliding block 63 is slidably disposed in the sliding groove. The upper end of the adjustment bracket 5 is threadedly connected to both sides of the adjustment screw 64. The adjustment screw 64 is rotatably provided with a fixed sleeve 65 in the sliding groove inside the adjustment bracket 5. A fixed rod 66 is slidably sleeved inside the fixed sleeve 65. The lower end of the fixed rod 66 is fixedly connected to the sliding block 63. A limit plate 67 is fixedly provided inside the fixed sleeve 65 at one end of the fixed rod 66. A spring 68 is sleeved on the surface of the fixed rod 66. One end of the spring 68 is fixedly connected to the limit plate 67. The other end of the spring 68 is fixedly connected to the bottom of the fixed sleeve 65. A second adjustment roller 69 is provided below the first adjustment roller 61. The two ends of the second adjustment roller 69 are rotatably connected to the inner side wall of the adjustment bracket 5 through bearings. In practical use, rotating the adjusting screw 64 pushes the fixed sleeve 65 up and down, thereby driving the first adjusting roller 61 to move vertically. This process is used to pre-set the initial pressure value according to the diameter of the copper rod (a larger initial pressure is required for copper rods with a larger diameter). This is a rigid mechanical adjustment to ensure the basic tension requirements of copper rods of different specifications during winding. When the winding speed of the copper rod fluctuates, the material is uneven, or the diameter changes slightly, the first adjusting roller 61 can move up and down slightly through the elastic deformation of the spring 68 to automatically compensate for tension fluctuations. If the diameter of the copper rod increases locally, it will push the first adjusting roller 61 upward, and the spring 68 will be further compressed. The elastic reaction will maintain stable clamping pressure and avoid deformation of the copper rod due to rigid compression. Conversely, if the diameter decreases, the spring 68 will rebound and push the first adjusting roller 61 downward to maintain constant tension, avoid equipment damage or copper strip breakage caused by direct collision of rigid structures, and extend the mechanical life.

[0026] The surfaces of the first adjusting roller 61 and the second adjusting roller 69 are both provided with diamond-shaped patterns. The roller surfaces are processed with fine mesh or diamond-shaped concave and convex patterns to increase the friction coefficient of the contact area and improve the stability of tension control. The gaps between the patterns can store a small amount of lubricant to reduce wear on the surface of the copper rod.

[0027] A support rod 7 is slidably mounted on the upper end of the base 1. The lower end of the support rod 7 is connected to the drive assembly 4. A rotating rod 8 is rotatably mounted on the upper end of the support rod 7. A guide ring 9 is fixedly mounted on the upper end of the rotating rod 8. A sponge pad is provided on the inner side wall of the guide ring 9. Its function is to prevent the copper rod from directly contacting the metal inner wall. Through the buffer isolation of the flexible material, the quality defects such as surface scratches, wear or scratches caused by rigid friction are effectively avoided. The copper rod enters from one end of the guide ring 9 and exits from the other end, then passes between the first adjusting roller 61 and the second adjusting roller 69 for tension adjustment. The guide ring 9 rotates slightly left and right relative to the support rod 7, with a slight rotation of ±90° to compensate for positional deviations. During the conveying process, the copper rod may shift laterally due to factors such as equipment vibration and roller wear. The micro-rotation function of the guide ring 9 can finely adjust the lateral position of the copper rod in real time, keeping it always in the center position of the adjusting roller, avoiding uneven tension caused by deviation. The rotatable design of the guide ring 9 avoids hard friction between the copper rod and the guide ring 9, reducing surface scratches, burrs and other damage.

[0028] The drive assembly 4 includes a connecting rod 41 slidably disposed inside the base 1. Positioning bushings 42 are fixedly disposed at both ends of the connecting rod 41. Positioning rods 43 are slidably sleeved inside the two positioning bushings 42. Both positioning rods 43 are connected to the inner side wall of the base 1. The upper end of one positioning bushing 42 is fixedly connected to the lower end of the adjusting bracket 5, and the upper end of the other positioning bushing 42 is fixedly connected to the lower end of the support rod 7. A motor is disposed at one end of the base 1. A lead screw is disposed on the output shaft of the motor. A slider is threadedly connected to the surface of the lead screw. The upper end of the slider is fixedly connected to the lower end of the connecting rod 41. The motor drives the slider, which is threadedly connected to the lead screw, to move back and forth. The slider drives the connecting rod 41 to move, and the connecting rod 41 drives the two positioning bushings 42 to slide on the positioning rod 43, thereby realizing the reciprocating movement of the adjusting bracket 5 and the support rod 7.

[0029] The base 1 is provided with multiple adjustable feet 10 at the four corners of its bottom end, which are used to flexibly adjust the height of the base 1. In actual production and use, the multiple adjustable feet 10 work together to increase the balance and stability of the device, improve the operability of leveling, increase the convenience of use, and reduce the limitations of use.

[0030] The working principle of this utility model is as follows: A tension adjustment frame for anti-winding copper rod production operates by using a motor to drive a connecting rod 41 and a positioning sleeve 42 to slide on a positioning rod 43. The positioning sleeve 42 then drives a support rod 7 and an adjusting bracket 5 to reciprocate, slowly winding the copper rod onto a winding roller 31. This prevents winding blind spots from forming at both ends of the winding roller 31, effectively improving the space utilization of the winding roller 31. To address the basic tension requirements of different specifications of copper rods during winding, an adjusting screw 64 drives a fixed sleeve 65 to move up and down, thereby adjusting the distance between the two adjusting rollers. An initial pressure value is preset according to the copper rod diameter (e.g., a larger initial pressure is required for thicker diameter copper rods). The spring 68 maintains moderate elastic deformation while maintaining constant tension, effectively preventing equipment damage or copper strip breakage due to rigid collisions, significantly extending the equipment's service life.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
