[0002] In many fields such as construction, agriculture, and industrial protection, wire mesh, as an important basic material, has a wide range of application requirements. The quality of wire mesh directly affects the performance and service life of related projects or products. The welding quality and production efficiency of wire mesh are the key factors to measure its manufacturing level. With the rapid development of various industries, the demand for wire mesh is increasing day by day. Traditional wire mesh welding methods and equipment gradually expose many problems and are difficult to meet the requirements of current high-efficiency and high-quality production.

[0003] In terms of electrical safety protection during the welding process, traditional equipment is lacking. Due to the lack of insulation protection measures, current is very likely to leak during conduction, especially in key parts such as near the electrodes. Once current leakage occurs, it is extremely easy to cause electrical faults such as short circuits. These faults will not only cause the welding work to be interrupted, affecting production efficiency, but also may damage the equipment, increasing maintenance costs and downtime.

[0014] (III) Beneficial effects The present invention provides a steel wire mesh welding machine, which has the following beneficial effects: (I). In this steel wire mesh welding machine, through the coordinated cooperation of components such as the coiling roller, cylinder, cam, and pressing rod in the feeding component, the intermittent conveying of the steel wire from the feeding hopper downward is realized. This feeding method according to a preset stable rhythm can ensure that the steel wire enters the welding area in an orderly manner, avoiding problems such as jamming and winding during the steel wire conveying process, enabling the entire welding process to proceed continuously and smoothly, thereby increasing the production quantity of the steel wire mesh per unit time and improving the overall production efficiency.

[0015] (II). In this steel wire mesh welding machine, by setting the pressing component, the conductive rod in the positioning component serves as the main structure for current conduction.

When the steel wire is closely attached to the electrode under the pressing action of the top plate, a stable and appropriate Joule heat can be generated at the contact part between the electrode and the steel wire, causing the metal at the contact point of the steel wire to rapidly heat up to the melting point.

[0016] (3) The wire mesh welding machine limits the transmission path and position of the wire before welding through the limiting channel composed of the lower rotating roller and the upper rotating roller in the limiting component, enabling the wire to enter the welding station at an accurate position and maintaining an appropriate tension. This avoids quality problems such as uneven welding points and false welding caused by wire position deviation, ensures that each welding point meets the quality requirements, and improves the overall welding quality and structural stability of the wire mesh.

[0017] (4) The wire mesh welding machine has a positioning component fixedly connected to the inner wall of the insulating shell. When the wire is pressed down to closely fit the electrode, stable and appropriate Joule heat can be generated at the contact part between the electrode and the wire, causing the metal at the wire contact point to rapidly heat up to the melting point. At the same time, the rubber blocks and connecting rings arranged in an annular array on the top of the installation table, on the one hand, the good insulation performance of the rubber blocks can prevent current leakage at non-welding parts and avoid electrical faults such as short circuits, enabling the welding heat to be concentrated at the wire contact points that need to be welded; on the other hand, the outer wall of the wire is pressed by the soft rubber blocks, thereby reducing damage to the wire.

[0021] Please refer to Figures 1-11 , the present invention provides a technical solution: a wire mesh welding machine, including: Fixing frame 1, the outer wall at the top of the fixing frame 1 is fixedly connected to the feeding hopper 3, and the outer wall at the bottom of the fixing frame 1 is fixedly connected with a limiting component 4; Electric welding device 2, the outer wall of the electric welding device 2 is fixedly connected to the outer wall of the fixing frame 1, the electric welding device 2 includes a feeding component 5, and the feeding component 5 is used to intermittently convey the steel wire in the feeding hopper 3 downward by rotation.

The inner wall at the bottom of the fixing frame 1 is fixedly connected with positioning columns 613, and the positioning columns 613 are linearly arranged along the outer wall of the fixing frame 1. When the telescopic rod 62 extends and pushes the connecting frame 64 to move downward, it is compressed. When the telescopic rod 62 retracts, it relies on its own elastic restoring force to assist the connecting frame 64 to reset, playing a role of buffering and assisting in resetting, and at the same time enhancing the stability of the entire pressing structure during the movement process.

[0022] The bottom of the connecting frame 64 is fixedly connected with a top spring 611, and the top springs 611 are linearly arranged along the central axis of the connecting rod 63. The inner wall of the connecting frame 64 is fixedly connected with sliding rods 614, and the sliding rods 614 are linearly arranged along the central axis of the connecting rod 63. The bottom of the sliding rods 614 is fixedly connected to the inner wall at the bottom of the fixing frame 1.

The outer wall of the insulating shell 69 is fixedly connected to the bottom of the connecting frame 64. The bottom of the compression spring 612 is fixedly connected to the inner wall at the bottom of the fixing frame 1. When the telescopic rod 62 moves downward to drive the cam 55 to rotate, the convex part of the cam 55 contacts the cylinder 53, and the contact will apply a torque to the coiling roller 52, enabling it to overcome its own rotational resistance and rotate by a certain angle, thereby realizing the intermittent release of the steel wire.

[0023] The positioning component 68 includes a conductive rod 681. An inner wall of the conductive rod 681 is fixedly connected with conductive columns 684, and the conductive columns 684 are linearly arranged along an outer wall of the conductive rod 681.

A top of the mounting table 687 is fixedly connected with rubber blocks 683, and the rubber blocks 683 are arranged in a circular array along a central axis of the mounting table 687. An outer wall of each rubber block 683 is fixedly connected with a connecting ring 685, and the connecting rings 685 are arranged in a circular array along the central axis of the mounting table 687.

An outer wall of the power input column 682 is fixedly connected with the inner wall of the insulating shell 69. An inner wall of a top of the insulating shell 69 is fixedly connected with an outer wall of a bottom of the mounting table 687. When the telescopic rod 62 moves downward and drives the welding column to move toward the electrode 686, when the welding column presses down the steel wire to be in close contact with the electrode 686, current enters the conductive rod 681 from the power input column 682, and then is conducted to the electrode 686 through the conductive column 684. At a contact part between the electrode 686 and the steel wire, it is connected with the current in the welding column. Due to the Joule heat generated by the passing current, the metal at the contact point of the steel wire rapidly heats up to the melting point.

[0024] The feeding component 5 includes a coiling roller 52. The coiling roller 52 is provided with an opening structure for the steel wire to pass through. An outer wall of the coiling roller 52 is fixedly connected with cylinders 53, and the cylinders 53 are arranged in a circular array along a central axis of the coiling roller 52. An inner wall of the coiling roller 52 is rotatably connected with a rotating shaft 54. Inner walls on both sides of the rotating shaft 54 are fixedly connected with connecting plates 58. An outer wall of the connecting plate 58 is rotatably connected with a cam 55 through a shaft body. An outer wall of the cam 55 is rotatably connected with a pressing rod 57 through a connecting shaft 56, and an outer wall of the connecting shaft 56 is rotatably connected with an inner wall of the pressing rod 57. An outer wall of the feeding hopper 3 is fixedly connected with a protective shell 51. There are two groups of the protective shells 51. An outer wall of the feeding hopper 3 is fixedly connected with an outer wall of the connecting plate 58. An outer wall of the cam 55 is in contact with an outer wall of the cylinder 53. A top of the pressing rod 57 is fixedly connected with an outer wall of the telescopic rod 62.

[0025] The limiting component 4 includes lower rotating rods 42. The lower rotating rods 42 are linearly arranged along an outer wall of the fixed frame 1. Outer walls on both sides of the lower rotating rods 42 are rotatably connected with support frames 41. Bottoms of the support frames 41 are fixedly connected with an outer wall of a bottom of the fixed frame 1. An outer wall of the fixed frame 1 is fixedly connected with an upper rotating rod 44 through a cross plate 43, and an outer wall of the cross plate 43 is fixedly connected with the outer wall of the fixed frame 1.

[0026] The wire mesh welding machine uses the fixed frame 1 as the basic support structure. The top outer wall is fixedly connected with the feeding hopper 3, which provides an inlet channel for the wire to enter the welding machine. The bottom outer wall is fixedly connected with a limiting component 4, which is used to accurately limit the position of the wire during the subsequent welding process. The electric welding device 2 is fixed on the outer wall of the fixed frame 1 and is the core execution part of the entire welding operation. It includes a wire feeding component 5 and a pressing component 6, which are responsible for the conveying of the wire and the pressing and welding operations related to welding respectively.

[0027] The wire feeding component 5 undertakes the key task of intermittently conveying the wire in the feeding hopper 3 downward. It is mainly composed of components such as a coiling roller 52, a cylinder 53, a rotating shaft 54, a cam 55, a pressing rod 57, and a connecting plate 58. The coiling roller 52 in the two groups of protective shells 51 is the key component for carrying the wire and is provided with an opening structure for the wire to pass through. The wire drops onto it orderly. The cylinders 53 arranged in a circumferential array along the central axis on its outer wall are in close cooperation with the cam 55 to achieve the transmission function. The rotating shaft 54 passes through the inner wall of the coiling roller 52 and is rotatably connected to it, and is fixedly connected to the outer wall of the feeding hopper 3 through the connecting plates 58 on both sides, thereby ensuring the rotational stability and relative position fixation of the coiling roller 52.

[0028] The cam 55 is rotatably connected to the connecting plate 58 through a shaft body. Its unique contour shape determines the intermittent characteristic of wire feeding. When the telescopic rod 62 moves downward to drive the cam 55 to rotate, the convex part of the cam 55 contacts the cylinder 53, and the contact applies a torque to the coiling roller 52, enabling it to overcome its own rotational resistance and rotate by a certain angle, thereby realizing the intermittent release of the wire.

[0029] The pressing rod 57 is rotatably connected to the cam 55 through a connecting shaft 56 and is fixedly connected to the outer wall of the telescopic rod 62 in the pressing component 6 at the top. During the operation of the pressing component 6, the telescopic movement of the telescopic rod 62 drives the pressing rod 57 to move up and down, and this up and down movement action will in turn act on the rotation of the cam 55. The two cooperate with each other through reasonable mechanical design and motion parameter matching to ensure that the wire is conveyed downward from the feeding hopper 3 to the welding area at a preset stable rhythm, meeting the strict requirements of the welding process for wire feeding.

[0030] The pressing component 6 is the key part for realizing wire pressing and welding, mainly including components such as a hydraulic cylinder 61, a telescopic rod 62, a connecting rod 63, a connecting frame 64, a limiting block 65, an insulating shell 69, and a positioning component 68. The hydraulic cylinder 61 is the power driving unit. According to Pascal's law, it drives the telescopic rod 62 to perform linear telescopic movement through the pressure change of the hydraulic oil in the cylinder body.

[0031] The telescopic movement of the telescopic rod 62 is transmitted to the connecting frame 64 through the connecting rod 63 fixedly connected thereto. The connecting frame 64 then transmits the force to the limit block 65. The limit block 65 slides along the inner wall of the insulating shell 69, and the insulating shell 69 provides a guiding channel for it to prevent the limit block 65 from having lateral offset or shaking during the up and down movement, ensuring that the components connected to the limit block 65 can stably limit the position where the steel wire drops downward along the vertical direction. The steel wire is guided by the outwardly expanding plates on both sides of the limit block 65. When the steel wire drops downward and contacts the outwardly expanding plate, it is guided by the outwardly expanding plate, thereby restricting the position of the steel wire, and facilitating the subsequent welding work.

[0032] The top springs 611 fixedly connected to the bottom of the connecting frame 64 are linearly arranged along the central axis of the connecting rod 63, and the bottom of the top springs 611 is fixedly connected to the inner wall of the bottom of the fixed frame 1. When the telescopic rod 62 extends and pushes the connecting frame 64 to move downward, the top springs 611 are compressed. When the telescopic rod 62 retracts, the top springs 611 rely on their own elastic restoring force to assist the connecting frame 64 to reset, playing a role in buffering and assisting in resetting, and at the same time enhancing the stability of the entire pressing structure during the movement process.

[0033] In addition, the sliding rods 614 fixedly connected to the inner wall of the connecting frame 64 are also linearly arranged along the central axis of the connecting rod 63. The bottom of the sliding rods 614 is fixedly connected to the inner wall of the bottom of the fixed frame 1. A sliding fit relationship is formed between the sliding rods 614 and the connecting frame 64, further guiding the up and down movement of the connecting frame 64 and the entire pressing assembly 6, ensuring that under different working conditions, the downward pressing action can always be carried out along the vertical direction, and ensuring that the oppression of the steel wire is uniform and stable.

[0034] The positioning assembly 68 fixedly connected to the inner wall of the insulating shell 69 plays a key role during the welding process. The conductive rod 681 in the positioning assembly 68 is the main structure for current conduction. An incoming current column 682 is fixedly connected to its outer wall, and the welding current required is accessed through an external welding power supply. The conductive columns 684 linearly arranged along the outer wall of the conductive rod 681 inside the conductive rod 681 are fixedly connected to the electrode 686 through the mounting table 687. When the telescopic rod 62 moves downward and drives the welding column to move towards the electrode 686, when the welding column presses down the steel wire to be in close contact with the electrode 686, the current enters the conductive rod 681 from the incoming current column 682, and then is conducted to the electrode 686 through the conductive columns 684. At the contact part between the electrode 686 and the steel wire, it is connected to the current in the welding column. Due to the Joule heat generated by the passing of the current, the metal at the contact point of the steel wire rapidly heats up to the melting point. Under the continuous pressure applied by the top plate 610, the contact points of adjacent steel wires achieve metallurgical bonding, completing the welding process. On the outer wall of the insulating shell 69, there are a fixed plate 66 and a rotating cylinder 67, and the rotation of the two rotating cylinders 67 restricts the steel wire conveyed to the electrode 686.

[0035] The rubber blocks 683 arranged in a circular array on the top of the mounting table 687 and the connecting ring 685 have two important functions. On the one hand, the good insulation performance of the rubber blocks 683 can effectively prevent current leakage at non-welded parts, avoid electrical faults such as short circuits, and ensure the safety and stability of the welding process. On the other hand, the connecting ring 685 enhances the connection strength between the electrode 686 and the mounting table 687, ensuring that the electrode 686 can still maintain an accurate position and good electrical conductivity under frequent welding operations and downward pressing forces, thereby ensuring the consistency and reliability of the welding quality. Moreover, the soft rubber blocks 683 press the outer wall of the steel wire, thus reducing damage to the steel wire.

[0036] The compression springs 612 fixedly connected to the bottom of the top plate 610 are arranged in a linear array along the central axis of the connecting rod 63, and the bottom of the compression springs 612 is fixedly connected to the inner wall of the bottom of the fixed frame 1. During the downward pressing of the top plate 610, the compression springs 612 undergo elastic deformation according to the actual feedback force of the steel wire, playing a buffering role. After the steel wire is welded and the telescopic rod 62 moves upward, the top plate 610 moves upward synchronously under the drive of the telescopic rod 62. Then, the welded steel wire mesh is pushed by the outer wall of the top plate 610, so as to push the steel wire mesh to move away from the top plate 610, thereby vacating a position for subsequent steel wire welding.

[0037] The limiting component 4 is mainly composed of components such as the lower rotating roller 42, the support frame 41, the cross plate 43, and the upper rotating roller 44. Its function is to limit the transmission path and position of the steel wire before welding. The lower rotating rollers 42 are arranged in a linear array along the outer wall of the fixed frame 1, and each lower rotating roller 42 is fixedly connected to the outer wall of the bottom of the fixed frame 1 through the support frames 41 on both sides. The support frames 41 have sufficient strength and stability to withstand various forces exerted by the steel wire during transmission, ensuring that the lower rotating rollers 42 always maintain a stable position and good rotation state during operation, enabling the steel wire to slide smoothly on its surface, reducing damage to the surface of the steel wire and energy loss caused by friction. The upper rotating roller 44 is fixedly connected to the outer wall of the fixed frame 1 through the cross plate 43. The cross plate 43 ensures the accurate installation position and height of the upper rotating roller 44 on the fixed frame 1. The upper rotating roller 44 also has good rotation performance and cooperates with the lower rotating roller 42 to form a transmission channel for clamping the steel wire up and down.

[0038] After the steel wire is conveyed out from the feeding component 5, it sequentially passes through the limiting channel composed of the lower rotating roller 42 and the upper rotating roller 44. In this channel, the position of the steel wire in the vertical direction is limited, effectively preventing the steel wire from bouncing up and down, shifting, etc., ensuring that the steel wire can enter the welding station below the pressing component 6 at an accurate position, and at the same time maintaining an appropriate tension, which not only avoids affecting the positioning accuracy during welding due to the steel wire being too loose, but also prevents the steel wire from being stretched and deformed or even broken due to excessive tension, providing a good prerequisite for subsequent stable and high-quality welding operations.
