Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire feeding technology for welding machines, specifically a wire feeding device for welding machines. Background Technology
[0002] A welding machine is an industrial device that uses heating, pressurization, or a combination of both to achieve atomic bonding at the joints of metal or non-metal workpieces, thereby forming a permanent joint. The wire feeding of the welding machine is for consumable electrode arc welding, such as carbon dioxide gas shielded welding and submerged arc welding. The core process refers to the process of using a special mechanical device to stably and accurately deliver the welding wire to the welding arc area at a preset speed.
[0003] In existing technologies, positioning is difficult, waiting time is long when frequently changing welding wire, significantly reducing work efficiency. There is no transition guide for wire lead-out, welding wires of different diameters are prone to bending and twisting, the angle of the incident wire feeding roller is unstable, exacerbating slippage and wire feeding speed fluctuations, the welding wire path is chaotic and prone to skipping and tangling, generating a large amount of bent waste during cleaning, and the surface is easily scratched, leading to coating peeling and end deformation. Consumable consumption is high, and the operation threshold is high; novices find it difficult to accurately adjust the installation and guide angles, easily causing welding defects such as uneven weld width and arc breakage. These defects, combined with inaccurate tension adjustment and poor vibration damping, create a vicious cycle, severely reducing the overall performance of the wire feeding system. Utility Model Content
[0004] The purpose of this utility model is to provide a wire feeding device for a welding machine to solve the problems mentioned in the background art, such as the inability to quickly install welding wire rolls and the lack of a suitable guiding structure, which leads to the need for tools for loading and unloading, difficulty in positioning, time-consuming wire replacement and reduced efficiency; the lack of guidance for welding wire, which makes it easy to bend and twist, resulting in large slippage and fluctuations in wire feeding; chaotic path, easy skipping and tangling, and high material consumption.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a welding machine wire feeding device, comprising a welding machine body, and further comprising an unwinding reel mounted on the welding machine body, a support mounting base fixedly connected to the welding machine body, a welding machine connector mounted on the welding machine body, a tension adjusting component mounted on the welding machine body, a rotating connecting rod fixedly connected to the support mounting base, a welding wire transmission disc rotatably connected to the rotating connecting rod, a fixed limiting shaft fixedly connected to the support mounting base, a limiting block rotatably connected to the fixed limiting shaft, a welding wire guide hole formed on the support mounting base, and a fixing component mounted on the limiting block, wherein the welding wire transmission disc is rotatably connected inside the groove of the support mounting base.
[0006] In the preferred embodiment of this technical solution, there are two rotating connecting rods, and the two rotating connecting rods are symmetrically and fixedly connected to the support mounting base.
[0007] In the preferred embodiment of this technical solution, the limiting block has a limiting groove at the corresponding position of the welding wire, and the welding wire is connected to the limiting groove for transmission.
[0008] In a preferred embodiment of this technical solution, the fixing component includes a fixing mounting block fixedly connected to the limiting block, a fixing mounting shaft mounted on the support mounting base, an adjusting support rod rotatably connected to the fixing mounting shaft, a fixing threaded rod fixedly connected to the adjusting support rod, and a fixing threaded extrusion rod threadedly connected to the fixing threaded rod, wherein the fixing threaded extrusion rod is in contact with the limiting block.
[0009] In the preferred embodiment of this technical solution, the limiting block has a slot at the corresponding position of the adjusting support rod, and the adjusting support rod is engaged inside the slot.
[0010] In the preferred embodiment of this technical solution, the support mounting base has a through groove at the corresponding position of the adjusting support rod, and the adjusting support rod rotates inside the through groove.
[0011] According to the preferred embodiment of this technical solution, the tension adjustment assembly includes a first motor fixedly connected to the welding machine body, a rotating connecting shaft fixedly connected to the output end of the first motor, an adjusting turntable fixedly connected to the rotating connecting shaft, a second motor fixedly connected to the adjusting turntable, a threaded screw fixedly connected to the output end of the second motor, an adjusting threaded block threadedly connected to the threaded screw, and a guide roller fixedly connected to the adjusting threaded block. The second motor drives the guide rollers on the threaded screw to move closer to or further away from each other.
[0012] In the preferred embodiment of this technical solution, there are two adjusting thread blocks, and the two adjusting thread blocks are symmetrically threadedly connected to the threaded screw.
[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. By integrating the unwinding reel, support mounting base, and limiting block into a single structure, the cumbersome bolt tightening steps of traditional wire loading and unloading devices are eliminated, significantly reducing positioning difficulty, shortening wire changing standby time, and improving work efficiency. The limiting slot of the limiting block, in conjunction with symmetrically arranged rotating connecting rods and welding wire transmission discs, provides transitional guidance constraints for the welding wire, preventing bending and twisting of welding wires of different diameters, ensuring a stable welding wire incident angle, and solving slippage and wire feeding speed fluctuation problems. By standardizing the welding wire feeding path, skipped wires and tangling phenomena are eliminated, reducing bending waste and preventing surface scratches on the welding wire, thus reducing consumable consumption. The simple and intuitive structural design lowers the operating threshold, allowing novices to quickly complete installation and guide angle adjustment, reducing weld defects. Simultaneously, in conjunction with the tension adjustment component, the stability of the wire feeding system is comprehensively improved.
[0014] 2. Adopting a dual-motor collaborative drive structure, the first motor drives the adjusting turntable to rotate, which can flexibly adjust the angle of the guide rollers to adapt to diverse wire feeding paths and avoid uneven tension caused by path deviation. The second motor drives the threaded screw, which drives two symmetrical adjusting threaded blocks and guide rollers to move closer or further away synchronously, enabling stepless tension control and precise matching of the clamping force for different diameter welding wires. This effectively prevents wire stretching deformation caused by excessive tension and slippage caused by insufficient tension. The symmetrical structure design ensures that the clamping force of the guide rollers on the welding wire is evenly distributed, ensuring that the welding wire is always in the center position, further improving wire feeding stability. This component works in conjunction with the device's limiting and guiding structure to break the vicious cycle of tension and guiding defects superimposed on traditional devices, significantly reducing the operating threshold and comprehensively improving the overall performance of the wire feeding system.

Detailed Implementation
[0017] 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.
[0018] Please see Figure 1-5This utility model provides an embodiment of a wire feeding device for a welding machine: it includes a welding machine body 1, a winding reel 2 mounted on the welding machine body 1, a support mounting base 3 fixedly connected to the welding machine body 1, a welding machine connector 4 mounted on the welding machine body 1, a tension adjusting assembly mounted on the welding machine body 1, a rotating connecting rod 801 fixedly connected to the support mounting base 3, a welding wire transmission disc 802 rotatably connected to the rotating connecting rod 801, a fixed limiting shaft 803 fixedly connected to the support mounting base 3, a limiting block 804 rotatably connected to the fixed limiting shaft 803, and a welding wire guide formed on the support mounting base 3. The welding wire drive disc 802 is rotatably connected to the groove of the support mounting base 3 via the hole 806 and the fixing component mounted on the limit block 804. Through the integrated structural design of the unwinding disc 2, the support mounting base 3, the tension adjustment component, the rotating connecting rod 801, the welding wire drive disc 802, the limit block 804 and the fixing component, the entire process of unwinding, guiding, tension adjustment and conveying of the welding wire is controlled in a closed loop. This effectively avoids problems such as wire deviation and entanglement during the conveying process. At the same time, the cooperation of each component improves the structural compactness and operational stability of the wire feeding device, reduces the overall space occupied by the device and adapts to the welding operation requirements under different working conditions.
[0019] Please see Figure 2 A further solution based on this embodiment is as follows: two rotating connecting rods 801 are provided, and the two rotating connecting rods 801 are symmetrically fixedly connected to the support mounting base 3. By using two symmetrically arranged rotating connecting rods 801 to support the welding wire transmission disk 802, the force on the welding wire transmission disk 802 can be kept uniform, avoiding tilting or jamming of the welding wire transmission disk 802 due to unilateral force, ensuring the contact stability between the welding wire and the welding wire transmission disk 802, thereby maintaining the consistency of the wire feeding speed and reducing weld quality defects caused by unstable transmission.
[0020] Please see Figure 2 A further solution based on this embodiment is as follows: the limiting block 804 has a limiting groove at the corresponding position of the welding wire, and the welding wire is connected in the limiting groove. By opening the limiting groove at the corresponding position of the welding wire in the limiting block 804, the welding wire can be precisely limited and constrained, restricting the lateral displacement of the welding wire during the conveying process, avoiding twisting, bending and other situations of the welding wire, ensuring that the welding wire always enters the welding wire guide hole 806 of the support mounting base 3 and the subsequent conveying process in a stable posture, and improving the accuracy of the angle at which the welding wire is injected into the welding area.
[0021] Please see Figure 3A further solution based on this embodiment is as follows: the fixing component includes a fixing mounting block 805 fixedly connected to the limiting block 804, a fixing mounting shaft 807 mounted on the support mounting base 3, an adjusting support rod 808 rotatably connected to the fixing mounting shaft 807, a fixing threaded rod 809 fixedly connected to the adjusting support rod 808, and a fixing threaded pressing rod 810 threadedly connected to the fixing threaded rod 809. The fixing threaded pressing rod 810 contacts the limiting block 804. By adjusting the rotation of the adjusting support rod 808 around the fixing mounting shaft 807 in conjunction with the thread adjustment of the fixing threaded pressing rod 810, the angle and pressing degree of the limiting block 804 can be flexibly adjusted to adapt to the limiting requirements of welding wires of different diameters. At the same time, the pressing force can be adjusted according to the characteristics of the welding wire material to avoid damage to the surface of the welding wire due to excessively tight limiting or welding wire falling off due to excessively loose limiting, thereby improving the versatility and adaptability of the device.
[0022] Please see Figure 3 A further solution based on this embodiment is as follows: the support mounting base 3 has a through groove at the corresponding position of the adjusting support rod 808. The adjusting support rod 808 rotates inside the through groove. By opening a through groove on the support mounting base 3 to allow the adjusting support rod 808 to rotate, a stable rotation space can be provided for the adjusting support rod 808, limiting the rotation range of the adjusting support rod 808 and avoiding failure of the fixing component due to excessive rotation. At the same time, the structural design of the through groove makes it easy for the operator to observe the position status of the adjusting support rod 808 from the outside, improving the convenience of operation.
[0023] Please see Figure 3 A further solution based on this embodiment is as follows: the support mounting base 3 has a through groove at the corresponding position of the adjusting support rod 808. The adjusting support rod 808 rotates inside the through groove. By opening a through groove on the support mounting base 3 to allow the adjusting support rod 808 to rotate, a stable rotation space can be provided for the adjusting support rod 808, limiting the rotation range of the adjusting support rod 808 and avoiding failure of the fixing component due to excessive rotation. At the same time, the structural design of the through groove makes it easy for the operator to observe the position status of the adjusting support rod 808 from the outside, improving the convenience of operation.
[0024] Please see Figure 4-5A further embodiment of this solution is as follows: the tension adjustment assembly includes a first motor 901 fixedly connected to the welding machine body 1, a rotating connecting shaft 902 fixedly connected to the output end of the first motor 901, an adjusting turntable 903 fixedly connected to the rotating connecting shaft 902, a second motor 904 fixedly connected to the adjusting turntable 903, a threaded screw 905 fixedly connected to the output end of the second motor 904, an adjusting threaded block 906 threadedly connected to the threaded screw 905, and a guide roller 907 fixedly connected to the adjusting threaded block 906. The guide rollers 907 on the drive screw 905 move closer or further apart. The first motor 901 drives the adjusting turntable 903 to rotate, which can flexibly adjust the angle of the guide rollers 907 to adapt to different wire feeding path requirements. At the same time, the second motor 904 drives the screw 905 to move the guide rollers 907 closer or further apart, which can precisely adjust the clamping force of the guide rollers 907 on the wire, thereby realizing stepless control of the wire tension. This avoids the wire from being stretched and deformed due to excessive tension or slipping due to insufficient tension, ensuring the stability and accuracy of the wire feeding process.
[0025] Please see Figure 4-5 A further solution based on this embodiment is as follows: two adjusting thread blocks 906 are provided, and the two adjusting thread blocks 906 are symmetrically threaded onto the threaded screw 905. By setting two adjusting thread blocks 906 symmetrically threaded onto the threaded screw 905, the two guide rollers 907 can move closer or further away synchronously and symmetrically, ensuring that the welding wire is always in the center position of the two guide rollers 907, avoiding the welding wire deviation caused by uneven force on the guide rollers 907. At the same time, the symmetrical structure can make the clamping force on the welding wire more uniform, further improving the accuracy of tension adjustment and the stability of wire feeding.
[0026] Working principle: First, the welding wire coil is installed on the unwinding reel 2. The end of the welding wire passes sequentially through the welding wire guide hole 806 of the support mounting base 3, the limiting groove of the limiting block 804, the welding wire transmission disc 802, and the guide roller 907 of the tension adjustment assembly, and finally connects to the welding machine connector 4. During the limiting and fixing stage, the adjusting support rod 808 is rotated to make it engage with the limiting block 804 slot. The fixed threaded extrusion rod 810 is screwed on, and the limiting block 804 is pressed by the thread transmission of the fixed threaded rod 809. This adapts to the diameter of the welding wire to complete the limiting and prevent the welding wire from shifting laterally. During the wire feeding stage, the welding wire transmission disc 802 rotates around the rotating connecting rod 801, and is constrained by the limit block 804 to guide the welding wire to be fed smoothly. When the tension adjustment component is activated, the second motor 904 drives the threaded screw 905 to rotate, which drives the two symmetrical adjusting threaded blocks 906 and the guide roller 907 to move closer or further away at the same time, so as to accurately control the tension of the welding wire clamping and avoid slippage or stretching deformation. The first motor 901 drives the adjusting turntable 903 to rotate through the rotating connecting shaft 902, and adjusts the angle of the guide roller 907 to adapt to different conveying path requirements.
