Description

Technical Field

[0001] This utility model relates to mesh covering hook welding equipment, and specifically refers to a width adjustment device for a mesh covering hook welding machine. Background Technology

[0002] The main structure of the composite steel mesh insulated exterior wall panel consists of main reinforcing meshes on both sides of a graphite polystyrene board, with secondary reinforcing meshes spaced apart on the outside of the main reinforcing meshes to form a frame. The two ends of the steel wires pass through the graphite polystyrene board and are welded to the main reinforcing meshes and secondary reinforcing meshes respectively. The steel wire mesh is attached to the surface of the secondary reinforcing meshes. The only difference between the composite steel mesh insulated interior wall panel and the composite steel mesh insulated exterior wall panel is that the latter does not contain graphite polystyrene board. Because of the impact of concrete during use, the steel wires are prone to detaching from the secondary and primary reinforcing meshes. Therefore, bending the exposed ends of the steel wires on the mesh surface is an essential structure in existing products. This structure can maintain the stability of the product structure even after the steel wires detach from the secondary and primary reinforcing mesh frames. Currently, there is no dedicated equipment to complete the bending operation. The bending operation is mainly completed manually using simple non-standard tools. If equipment is used to automate the production of composite steel mesh insulation wall panels, welding the exposed steel wires on the primary reinforcing mesh to the secondary reinforcing mesh is an essential step in completing the above operation. Welding wire equipment is widely reported in existing literature and commercially available products are available. Since the thickness specifications of the processed mesh frame vary, the design of the matching width adjustment device becomes the key technology for completing the above automated operation. At the same time, the design of the width adjustment device also needs to consider the effective connection with the subsequent traction, welding wire, and steel wire bending processes.

[0003] The applicant has retrieved the following existing patent documents:

[0004] Patent document CN213564459U discloses a vertical steel wire mesh insulation board forming machine. This wire insertion device 3, through a pusher 34, drives several top rods 35 to move, allowing simultaneous, same-angle, same-speed, and same-force insertion of wires into the polystyrene board. Because the position of the second fixing plate 32 is changeable, it can adapt to polystyrene boards of different widths, solving the problem of the inability to further thicken the polystyrene board. The length of the material trough also provides sufficient redundancy to accommodate polystyrene boards of different widths. The existing technology has several problems. First, the second fixing plate 32 is a component of the wire insertion device; therefore, its adjustment cannot change the adaptability to the material thickness. Furthermore, the specification does not explain the adaptive adjustments to the material conveying device based on different material thicknesses. Therefore, this existing technology is not suitable for processing main rib meshes of different thicknesses. Since subsequent welding and bending operations require high precision at the welding points and bends, the existing technology cannot meet the requirements of the traction, welding wire, and hook mechanisms and subsequent operations after feeding. The applicant has not found any literature reports that are the same as or similar to this utility model in domestic patent databases. Summary of the Invention

[0005] The purpose of this utility model is to provide a width adjustment device for a mesh bending and welding machine, which can effectively process main rib meshes of different thicknesses, thereby providing reliable structural support for the layout of subsequent traction, welding wire, and bending mechanisms, as well as standardized and rapid operations under precise positioning.

[0006] The overall technical concept of this utility model is:

[0007] The width adjustment device of the wire mesh hook welding machine includes a main frame and a movable frame set on the main frame and forming a material conveying channel therewith. The movable frame and the main frame are adjustable in distance along the direction perpendicular to the material conveying direction through a drive mechanism. The drive mechanism adopts one or a combination of a gear and rack transmission pair, a parallelogram mechanism, and a screw feed mechanism. The bottom of the movable frame is assembled with the main frame along the direction perpendicular to the material conveying direction through a guide rail and a guide wheel that rolls with it.

[0008] The applicant should explain that the main function of the drive mechanism is to adjust the distance between the movable frame and the main frame, thereby changing the width of the material conveying channel by changing the distance. Therefore, material conveying channels of different widths can be used to accommodate space frames of different thicknesses, enabling subsequent traction, welding, and bending operations for space frames of different specifications.

[0009] Other specific technical solutions of this utility model include:

[0010] The main function of the guide wheels and guide rails is to facilitate flexible movement when adjusting the distance between the movable frame and the main frame. To meet the above requirements, the preferred technical means is to set the guide wheels at the bottom of the movable frame and fix the guide rails to the bottom upper surface of the main frame.

[0011] The main function of the drive mechanism is to provide power for adjusting the distance between the movable frame and the main frame. In order to achieve consistent adjustment of the distance between the movable frame and the main frame, not only can the material conveying channel adapt to the conveying of mesh frames of different widths, but also meet the technical requirements of precise station positioning during subsequent wire welding and bending operations, so as to realize continuous production under accurate positioning of traction, wire welding and bending. The preferred technical means is that the drive mechanism adopts a lead screw feeding mechanism, including at least three lead screw nuts fixed on the movable frame. The lead screw nuts form a plane parallel to the material conveying direction. The outer end of the lead screw is set on the main frame and driven by the drive wheel.

[0012] Furthermore, the drive wheel can be a handwheel, or a combination of a handwheel and a sprocket chain drive.

[0013] The drive wheel can be driven individually or synchronously, both without departing from the essence of this utility model. To simplify the structure and achieve synchronous adjustment of the distance between the movable frame and the main frame, ensuring the accuracy of the adjustment, the preferred technical implementation is that the drive wheel adopts a handwheel and sprocket chain transmission pair. The sprocket chain transmission pair includes sprockets and a chain connecting the sprockets, with a handwheel coaxially fixed to one of the sprockets. In this way, rotating the handwheel can achieve synchronous rotation of each sprocket through the chain, and then achieve synchronous feeding of the lead screw through the lead screw feed mechanism, thus completing the synchronous and precise adjustment of the distance between the main frame and the movable frame.

[0014] Furthermore, there are four sets of lead screw feed mechanisms, arranged symmetrically between the movable frame and the main frame.

[0015] The technological advancements achieved by this utility model are as follows:

[0016] 1. This utility model adopts a structural design with an adjustable distance between the movable frame and the main frame. Firstly, it facilitates the conveying of main rib meshes with different thicknesses. Secondly, since traction, welding wire, and bending devices can be installed on the movable frame and the main frame, this structural design provides a reliable structural guarantee for the subsequent arrangement of traction, welding wire, and bending mechanisms, as well as standardized and rapid production under precise positioning.

[0017] 2. The structural design of the drive mechanism can meet the needs of individual or coordinated adjustment, both of which enable adjustable spacing between the main frame and the movable frame. The coordinated adjustment achieved using a sprocket and chain drive pair allows for rapid, synchronized, and precise spacing adjustments, thus meeting the requirements of standardized production.

[0018] 3. This utility model adopts a structural design of guide wheels and guide rails, which improves the flexibility of component matching, facilitates the reduction of load and work intensity when adjusting the spacing. Attached Figure Description
