Description

A traction device for metal wire mesh production Technical Field

[0001] The embodiments disclosed herein relate to the technical field of metal wire mesh production, and more specifically, to a traction device for metal wire mesh production. Background Technology

[0002] In the production of metal wire mesh, the traction device is a key piece of equipment to ensure the stable transport of metal wire, and its performance directly affects the quality and production efficiency of the metal wire mesh. However, existing traction devices for metal wire mesh production generally have significant defects and are difficult to meet the requirements of high-precision production.

[0003] Traditional traction devices often employ fixed roller sets or simple mechanical transmission structures, lacking an effective tension adjustment mechanism. They cannot adjust tension in real time based on factors such as wire material characteristics, equipment vibration, or transmission wear, leading to uneven tension during traction. Excessive tension can cause the wire to break due to overstretching; insufficient tension causes wire slack and slippage during transport, resulting in quality defects such as uneven mesh size and structural deformation in the subsequently woven mesh. Furthermore, existing devices rely on manual tension adjustment, which is not only cumbersome and inefficient but also lacks precision, failing to achieve dynamic calibration and severely impacting production continuity and product consistency.

[0004] Uneven tension can exacerbate wear and tear on equipment components and increase downtime maintenance costs. This is especially true for high-precision wire mesh (such as electronic shielding mesh and medical filter mesh), where tension imbalance directly leads to higher scrap rates, making it difficult to meet the stringent requirements of high-end applications. With the increasing automation and precision in the industry, the development of a traction device capable of flexibly adjusting tension and balancing it in real time is urgently needed to address issues such as lagging tension adjustment and frequent manual intervention in existing technologies. This would ensure constant and uniform tension during wire conveying, improve production quality and efficiency, and reduce losses. Summary of the Invention

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a traction device for metal wire mesh production, which solves the technical problem in the prior art that the tension cannot be adjusted in real time according to factors such as the material characteristics of the metal wire, equipment vibration or transmission wear, which easily leads to uneven tension during the traction process.

[0006] According to one aspect, at least one embodiment of the present disclosure provides a traction device for producing metal wire mesh, characterized in that it comprises:

[0007] A base frame and a center frame, wherein the center frame is mounted on the base frame;

[0008] A pair of side plates and a connecting adjustment assembly, wherein the side plates are disposed between the central frame and the base frame, and the connecting adjustment assembly is disposed on the side plates and the central frame;

[0009] A traction retaining assembly, which is disposed on the side plate and the center frame;

[0010] The connection adjustment assembly includes a pair of movable rods, which are fixed at both ends of the bottom of the central frame. The movable rods are movably connected to the base frame, and an adjustment screw is threadedly connected inside the base frame. The upper end of the adjustment screw is rotatably connected to the bottom of the central frame.

[0011] As a further technical solution, a pair of connecting rods are provided at both ends of the base frame, and the side plate is rotatably connected between the pair of opposing connecting rods by a pin shaft. A pair of sliding grooves are provided at both ends of the surface of the base frame.

[0012] As a further technical solution, a slider is slidably embedded in the groove, and a pair of connecting blocks are provided at the lower end of the side plate. The connecting blocks and the slider are rotatably connected by a pin.

[0013] As a further technical solution, the traction holding assembly includes several pairs of straightening wheels, all of which are rotatably connected within the central frame. The straightening wheels are distributed vertically, and a pair of circular grooves are provided at the bottom of the side plate.

[0014] As a further technical solution, a stabilizing rod is movably connected inside the circular groove, a spring is fitted on the stabilizing rod, a side block is provided at the upper end of the stabilizing rod, and the side plate is rotatably connected between the side blocks by a pin.

[0015] As a further technical solution, the side blocks are rotatably connected by a rotating shaft, the side plate surface is provided with a number of traction grooves, the rotating shaft is provided with a number of pressure rollers, and the lower end of the pressure rollers is located in the traction grooves.

[0016] As a further technical solution, the groove and the slider have a T-shaped cross-section.

[0017] As a further technical solution, the thickness of the pressure roller is matched with the inner width of the groove.

[0018] As a further technical solution, the surface of the straightening wheel has a concave structure, and the concave portion of the straightening wheel surface matches the diameter of the metal wire.

[0019] The beneficial effects of the embodiments disclosed herein are as follows:

[0020] 1. In this disclosure, the beneficial effect of the connecting adjustment component is that the movable rod cooperates with the adjusting screw, and the vertical lifting of the center frame is achieved by rotating the adjusting screw, thereby driving the side plate to rotate and adjust the angle. It can dynamically adjust the tension of the metal wire in real time according to the material characteristics of the metal wire, equipment vibration and other factors, effectively solving the problem that traditional devices cannot flexibly adjust the tension, so that the metal wire maintains constant tension during the traction process, avoiding breakage or loosening caused by uneven tension, and improving the stability and consistency of metal wire mesh production.

[0021] 2. The beneficial effect of the traction holding assembly in this disclosure is that the upper and lower distributed straightening wheels, through their concave structure, match the diameter of the metal wire, enabling precise clamping and guiding of the metal wire and preventing deviation during conveying. The pressure rollers on the side plate press the metal wire under the action of springs, and cooperate with the traction groove to increase friction, avoiding slippage and ensuring stable conveying of the metal wire along the predetermined path. This assembly works in conjunction with the connecting adjustment assembly, not only realizing dynamic adjustment of tension but also ensuring the conveying accuracy of the metal wire, reducing quality defects caused by uneven tension and conveying deviation, and improving the production quality and efficiency of the metal wire mesh.

[0033] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0034] As shown in Figures 1-4, a traction device for producing metal wire mesh according to an embodiment of this disclosure is illustrated, comprising:

[0035] A base frame 1 and a center frame 2, wherein the center frame 2 is mounted on the base frame 1;

[0036] A pair of side plates 3 and a connecting adjustment assembly 4, wherein the side plates 3 are disposed between the central frame 2 and the base frame 1, and the connecting adjustment assembly 4 is disposed on the side plates 3 and the central frame 2;

[0037] Traction retaining assembly 5, which is disposed on the side plate 3 and the center frame 2;

[0038] The connecting adjustment assembly 4 includes a pair of movable rods 4-1, which are fixed at both ends of the bottom of the central frame 2. The movable rods 4-1 are movably fitted into the base frame 1. An adjusting screw 4-2 is threadedly connected to the base frame 1. The upper end of the adjusting screw 4-2 is rotatably connected to the bottom of the central frame 2. A pair of connecting rods 4-3 are provided at both ends of the base frame 1. The side plate 3 is rotatably connected between the pair of opposing connecting rods 4-3 by a pin. A pair of sliding grooves 4-4 are provided at both ends of the surface of the base frame 1. A slider 4-5 is slidably embedded in the sliding grooves 4-4. A pair of connecting blocks 4-6 are provided at the lower end of the side plate 3. The connecting blocks 4-6 and the sliders 4-5 are rotatably connected by a pin.

[0039] In some examples, during the wire mesh production process, in order to flexibly adjust the angle between the side plate 3 and the central frame 2, and thus cooperate with the traction holding assembly 5 to achieve the effect of adjusting the tension of the wire conveying, a connecting adjustment assembly 4 is designed. This assembly includes a pair of movable rods 4-1 fixed at both ends of the bottom of the central frame 2. The movable rods 4-1 are movably fitted inside the base frame 1. This installation method provides the central frame 2 with a vertical sliding effect, allowing the central frame 2 to stably change height within the base frame 1. An adjusting screw 4-2 is threadedly connected inside the base frame 1, and its upper end is rotatably connected to the bottom of the central frame 2. When the operator rotates the adjusting screw 4-2, the rotational motion of the screw can be converted into the vertical lifting motion of the central frame 2, thereby driving the side plate 3 to adjust its angle. A pair of connecting rods 4-3 are set at both ends of the base frame 1, and the side plate 3 is rotated through a pin. Connected between a pair of opposing connecting rods 4-3, providing a fulcrum for the rotation of the side plate 3, a pair of sliding grooves 4-4 are opened at both ends of the surface of the base frame 1. A slider 4-5 is slidably embedded in the sliding grooves 4-4 and is rotatably connected to a pair of connecting blocks 4-6 set at the lower end of the side plate 3 via a pin. When the center frame 2 is raised and lowered under the action of the adjusting screw 4-2, the slider 4-5 will slide in the sliding groove 4-4, and at the same time drive the side plate 3 to rotate around the pin connected to the connecting rod 4-3, thereby realizing the precise adjustment of the angle between the side plate 3 and the center frame 2. Through this structural design, changing the angle between the side plate 3 and the center frame 2 can change the degree of tension of the wire mesh during the traction process, thereby cooperating with the traction holding component 5 to achieve the effect of adjusting the tension of the wire mesh, ensuring that the wire mesh maintains a proper tension during the production process, and avoiding the impact of improper tension on product quality.

[0040] As shown in Figures 1 to 4, this embodiment proposes that the traction and holding assembly 5 includes several pairs of straightening wheels 5-1, all of which are rotatably connected to the central frame 2. The straightening wheels 5-1 are distributed vertically. A pair of circular grooves 5-2 are provided at the bottom of the side plate 3. A stabilizing rod 5-3 is movably connected to the circular groove 5-2. A spring 5-4 is fitted on the stabilizing rod 5-3. A side block 5-5 is provided at the upper end of the stabilizing rod 5-3. The side plate 3 is rotatably connected between the side blocks 5-5 by a pin. A rotating shaft 5-6 is rotatably connected between the side blocks 5-5. Several traction grooves 5-7 are provided on the surface of the side plate 3. Several pressure rollers 5-8 are provided on the rotating shaft 5-6. The lower end of the pressure roller 5-8 is located in the traction groove 5-7.

[0041] In some examples, during the traction process of the wire mesh, in order to effectively limit the conveying position of the wire mesh, avoid deviation, and ensure the conveying accuracy and production quality of the wire mesh, a traction holding assembly 5 is designed. This assembly includes several pairs of straightening wheels 5-1 rotatably connected within the central frame 2 and distributed vertically. These straightening wheels 5-1 clamp and guide the wire mesh from both vertical and horizontal directions. When the wire mesh deviates during conveying, the straightening wheels 5-1 can promptly correct its position. Through contact and friction with the wire mesh, they pull the wire mesh back to the predetermined conveying path, ensuring that the wire mesh moves in the correct direction. A pair of circular grooves 5-2 are opened at the bottom of the side plate 3, and springs 5 ​​are fitted on the stabilizing rods 5-3 that are movably connected within the grooves. -4. The side block 5-5 is set at the upper end of the stabilizing rod 5-3. The side plate 3 is rotatably connected between the side blocks 5-5 by a pin. The elasticity of the spring 5-4 enables the stabilizing rod 5-3 and the side block 5-5 to generate a certain downward pressure. The rotating shaft 5-6 rotatably connects the side blocks 5-5. The lower ends of the several pressure rollers 5-8 set on the shaft are located in several traction grooves 5-7 opened on the surface of the side plate 3. During the conveying process of the wire mesh, the pressure rollers 5-8 roll in the traction grooves 5-7, pressing the wire mesh tightly in the traction grooves 5-7. This not only increases the friction between the wire mesh and the traction device and prevents the wire mesh from slipping, but also further restricts the horizontal movement of the wire mesh, ensuring that the wire mesh is always in the predetermined conveying position and effectively avoiding deviation.

[0042] For example, as shown in Figure 3, the cross-sections of the groove 4-4 and the slider 4-5 are T-shaped.

[0043] In some examples, the T-shaped structure provides a limiting effect when the slider 4-5 moves within the groove 4-4, preventing it from falling off or wobbling.

[0044] For example, as shown in Figure 3, the thickness of the pressure roller 5-8 matches the inner width of the groove 4-4.

[0045] In some examples, by matching the dimensions, there is no gap between the pressure roller 5-8 and the inner wall of the groove 4-4, so that the metal wire will not get stuck.

[0046] For example, as shown in Figure 3, the surface of the straightening wheel 5-1 has a concave structure, and the concave portion of the surface of the straightening wheel 5-1 matches the diameter of the metal wire.

[0047] In some examples, the concave structure allows the metal wire to be stably held within the concave portion of the straightening wheel 5-1, resulting in better stability.

[0048] In practical use: the metal wire is passed through the straightening wheels 5-1 distributed vertically inside the center frame 2, so that the metal wire is embedded in the concave part of the straightening wheel 5-1. According to the metal wire material and production requirements, the adjusting screw 4-2 is rotated. The adjusting screw 4-2 drives the center frame 2 to move up and down along the movable rod 4-1 through the threaded engagement. When the center frame 2 is raised and lowered, the side plate 3 is driven to rotate around the connecting rod 4-3 through the pin shaft. The connecting block 4-6 at the lower end of the side plate 3 drives the slider 4-5 to slide in the T-shaped slide groove 4-4 of the base frame 1, thereby adjusting the angle between the side plate 3 and the center frame 2. At the same time, the connecting rod 4-3 in the circular groove 5-2 at the bottom of the side plate 3, under the action of the spring 5-4, causes the pressure wheel 5-8 to press against the metal wire in the traction groove 5-7 through the side block 5-5 and the rotating shaft 5-6, thereby adjusting the tension of the metal wire and ensuring that the metal wire maintains a suitable tension during the traction process.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
