Description

Technical Field

[0001] This utility model relates to wire insertion welding equipment, and in particular to a width adjustment device for a wire insertion welding machine. Background Technology

[0002] Inserting wires into the foam board and welding the exposed ends of the wires to the mesh is an essential structure for composite steel mesh insulation panels, and also one of the necessary steps in the production of this product. Currently, there is no universal equipment to complete the above process. Some manufacturers produce it manually, which makes it difficult to achieve standardized and rapid production. The angle of the inserted wires, the flatness of the mesh after welding, and the welding quality are not easy to guarantee. Other manufacturers complete the above operations using customized equipment. This customized equipment is generally a horizontal non-standard machine. The main problems are: first, the feeding thickness and wire feeding angle are not adjustable, and it can only produce composite steel mesh insulation panels of a fixed thickness; second, due to the horizontal structure and the fixed frame structure of the main unit, the length of the composite insulation panel is limited, resulting in fewer product specifications; third, during welding, the mesh is laid flat, and the distance between the mesh and the core material is maintained by the hook driven by the cylinder. Due to the point connection, the consistency of the distance between the mesh and the core material is poor, resulting in poor flatness of the welded mesh.

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

[0004] A utility model patent with patent number 202022132349 discloses a vertical steel wire mesh insulation board forming machine, whose main structure includes a conveying device, a wire insertion device, and a welding device. The conveying device is used to transport polystyrene boards, the wire insertion device is used to insert wires into the polystyrene boards, and the welding device is used to weld the inserted wires to the steel wire mesh. The main problem with the above-mentioned prior art is that it cannot achieve wire insertion and welding operations for different polystyrene board thicknesses, thus greatly limiting the range of processed products. 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 wire insertion welding machine, which can effectively realize the feeding and conveying of mesh frames with different thickness specifications, thereby providing reliable structural support for the precise positioning and standardized rapid operation of subsequent wire feeding, wire insertion, and welding.

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

[0007] The width adjustment device of the wire insertion 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 lead screw feeding 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 needs to 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, realizing the arrangement and operation of subsequent traction, wire insertion, and wire welding mechanisms 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 implementation is that the guide wheels are located at the bottom of the movable frame and the guide rails are fixed to the upper surface of the bottom 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. This enables continuous production under the accurate positioning of wire traction, wire insertion, and wire welding. The preferred technical means is that the drive mechanism adopts a screw feeding mechanism, including at least two screw nuts fixed on the movable frame, with the outer end of the screw 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 a first sprocket coaxially fixedly mounted with a nut, a second sprocket, and a chain forming the transmission pair with the two. A handwheel is coaxially fixedly fitted on the first sprocket and / or the second sprocket. In this way, rotating the handwheel can achieve synchronous rotation of each sprocket through the chain, and then achieve synchronous feeding of the screw through the screw feed mechanism, thus completing the synchronous and precise adjustment of the distance between the main frame and the movable frame.

[0014] The technological advancements achieved by this utility model are as follows:

[0015] 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 mesh frames with different thickness specifications. Secondly, since the movable frame and the main frame can be equipped with wire feeding, welding, and bending devices, this structural design provides a reliable structural guarantee for the subsequent arrangement of traction, wire feeding, and welding mechanisms, as well as the accuracy of the workstation during operation.

[0016] 2. The structural design of the drive mechanism can meet the needs of individual or coordinated adjustment, both of which can achieve adjustable spacing between the main frame and the movable frame. The coordinated adjustment achieved using a sprocket and chain drive pair can quickly achieve synchronous and precise spacing adjustment.

[0017] 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
