Description

Technical Field

[0001] The present application relates to the technical field of mesh welding machines, and in particular to a mesh welding machine with an automatic feeding function. Background Art

[0002] The mesh welding machine is a welding device that welds the straightened wire rod steel bars according to the transverse bars and the longitudinal bars to form a mesh. For example, "CN114055020A, a fully automatic mesh welding machine" discloses a mesh welding machine. When it is running, "the controller sends a signal to the warp steel bar conveying mechanism to input the warp steel bars into the welding mechanism, and at the same time sends a signal to the weft steel bar sorting mechanism and the single weft steel bar feeding mechanism to feed the weft steel bars into the welding mechanism. Then the controller sends a signal to the welding mechanism for welding. When the welding mechanism completes the welding of the first row of welds, the controller sends a signal to the welding mechanism. The controller sends a signal to the mesh-pulling mechanism to make it pull the mesh for transportation. At this time, the mesh can be moved only by the mesh-pulling mechanism. When the welding mechanism is welding, the mesh-pulling mechanism, the warp steel bar conveying mechanism and the single weft steel bar sending mechanism all stop running. When the mesh moves to the truss installation mechanism, the controller sends a signal to the mesh transmission mechanism to realize the transportation of the mesh. By controlling the running time of the mesh transmission mechanism, the mesh reaches the preset position, and then sends a signal to the truss installation mechanism to install and weld the truss. Then the controller sends a signal to the bending mechanism to realize the bending of the mesh.

[0003] Existing mesh welding machines usually use electric control for conveying, such as the mesh pulling mechanism in the above patent document "The mesh pulling mechanism is located below the frame, including a connecting rod connected to the frame through a mesh pulling drive assembly, a hook connected to the mesh pulling drive assembly through a rotating assembly, and a fifth cylinder with both ends hinged to the hook and the rotating assembly. The mesh pulling drive assembly includes a fourth guide rail and a fourth slider for guiding and supporting functions correspondingly arranged on both sides of the frame (this is the prior art and will not be described here), a second rack, a second gear, and a fourth servo motor for driving the second gear to rotate. The rotating assembly is a rotating rod connected to the mesh pulling drive assembly through a bearing, and a connecting rod connected to the mesh pulling drive assembly through a bearing. There are multiple connecting rod brackets on the rotating rod, and the pull hook is connected to the rotating rod. The frame is provided with a plurality of mesh support brackets consistent with the movement direction of the mesh pulling drive assembly, which are used to support the mesh. "The mesh after welding is pulled backward by the pull hook. Most of the existing other types of mesh conveying structures are similar to this device; but the above structure has the following problems. First, there is usually a gap between the downward position of the hook and the horizontal steel bar, so it may not move into place at the initial position. In addition, a single conveying structure needs to be reset after running a certain distance, so there will be a short pause between the two actions, which will reduce the processing rate of the device. Therefore, in order to solve the above problems, the present application provides a mesh welding machine with automatic feeding function. Utility Model Content

[0021] The following is combined with Figure 1 - Figure 5 This application is described in further detail. Example

[0022] Reference Figure 1 - Figure 5 A mesh welding machine with automatic feeding function includes a frame 1, and a plurality of horizontal slide bars 11 are evenly distributed in the middle of the frame 1. The mesh 2 after welding slides on the frame 1, and a feeding mechanism 3 is arranged under the frame 1. The feeding mechanism 3 includes two push rods 36 sliding in the horizontal direction. The movement trend of the two push rods 36 is symmetrically arranged. The two push rods 36 include two strokes of pushing and resetting with smooth transition between each other. The push stroke push rod 36 protrudes from the upper end surface of the slide bar 11, and the reset stroke push rod 36 is located below the lower end surface of the slide bar 11.

[0023] A notched guide frame 33 is provided on one side of the two push rods 36. The upper section of the guide frame 33 corresponds to the pushing stroke, and the lower section corresponds to the resetting stroke. Arc-shaped transition sections are provided at both ends of the guide frame 33. A pin shaft 351 slidably embedded in the guide frame 33 is welded on one side of the two push rods 36 close to the guide frame 33. The guide frame 33 can be vertically displaced while the transmission rod 35 pushes in the horizontal direction. When the push rod 36 is in the pushing stroke, one side of it contacts the transverse steel bars in the mesh 2, thereby pushing the whole to slide to one side. When the push rod 36 reaches the transition section at the end, the push rod 36 is The rod 36 moves downward and breaks away from the contact with the mesh 2, and at this time, the other push rod 36 enters the pushing stroke from the reset stroke, but the push rod 36 that has just entered the pushing stroke does not contact the transverse reinforcement of the mesh 2, and this spare transmission process overlaps with the welding operation time of the front welding mechanism, thereby avoiding unnecessary waiting time. After the front welding mechanism completes the welding, the push rod 36 at this time contacts the transverse reinforcement of the mesh 2 on its front side and pushes again, and so on and so forth, completing the welding operation of all the transverse reinforcements, without any unnecessary waiting time in the process, and the feeding mechanism 3 has a simple structure and no complicated control system, thereby reducing the cost of the device.

[0024] A slide groove 361 is provided on the side of the push rod 36 facing away from the guide frame 33, and a motor 34 is arranged on the outer side of the side of the push rod 36 where the slide groove 361 is provided, and the output end of the motor 34 is fixedly connected to the transmission rod 35, and a second pin shaft 363 slidably embedded in the slide groove 361 is welded on the transmission rod 35. When the motor 34 rotates together with the transmission rod 35, the second pin shaft 363 thereon slides in the slide groove 361, pushing the push rod 36 to move in the horizontal direction, and cooperating with the function of the upper guide frame 33, the push rod 36 can move in the vertical direction while moving horizontally.

[0025] The bottom end of the push rod 36 is provided with a limiting section 362 of a rectangular structure, and the outer sliding sleeve of the limiting section 362 has a sliding frame 32. The function of the limiting section 362 and the sliding frame 32 is to ensure that the push rod 36 can operate stably. Preferably, the inner side of the limiting section 362 is slidably connected to a rectangular rod, and the rectangular rod can move up and down on the limiting section 362. The rectangular rod slides horizontally on the inner side of the sliding frame 32. In this way, it can be ensured that the push rod 36 will not tip over during operation. The upper sliding frame 37 can also be replaced with the same structure to further improve stability. The top of the push rod 36 also has a sliding sleeve with a sliding frame 37, and the sliding frame 37 and the slide bar 11 are fixedly connected with bolts.

[0026] A bracket 31 is welded between the two sliding frames 32, and the bracket 31 is fixedly connected to the external structure. The motor 34 and the guide frame 33 are fixedly connected by bolts between the connecting frame and the bracket 31 to ensure the stability of the overall device structure during operation.

[0027] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
