Description

Technical Field

[0001] This utility model relates to wire insertion welding equipment, and in particular to a wire feeding 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 structural element of composite steel mesh insulation panels, and also a necessary step in the production of this product. Currently, there is no universal equipment to complete this 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 easily guaranteed. Other manufacturers complete the above operations using customized equipment. This customized equipment is generally a horizontal non-standard machine, and the main problems are: first, the feed thickness and wire feeding angle are not adjustable, so 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.

[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 invention is to provide a wire feeding device for a wire insertion welding machine, which can effectively perform wire insertion operations on mesh frames with different thicknesses, thereby providing reliable structural support for the subsequent precise operation of welding wire and standardized rapid operation.

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

[0007] The wire feeding device of the wire insertion welding machine includes a main frame, a second bracket set on one side of the main frame with the wire outlet end corresponding to the conveying channel of the mesh frame, and a wire feeding mechanism driven by a linear drive mechanism on the second bracket; the second bracket consists of two symmetrically distributed members that are relatively perpendicular to the conveying channel of the mesh frame, the front of the second bracket is rotatably engaged with the main frame, the bottom of the second bracket is mounted on the upper surface of the first bracket, and a screw feeding mechanism for adjusting the distance between the two opposing second brackets is provided.

[0008] The design of using a structure in which the front of the second bracket rotates in conjunction with the main frame and the bottom of the second bracket is mounted on the upper surface of the first bracket is primarily for two reasons: firstly, to ensure that the spacing of the second bracket can be adjusted by rotating its front end under the drive of the lead screw feeding mechanism; and secondly, to provide a relatively stable support foundation for stable wire feeding operation.

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

[0010] The lead screw feeding mechanism preferably adopts the following mechanism: the lead screw feeding mechanism includes a lead screw whose outer end is flexibly engaged with the second bracket, and the inner end of the lead screw is connected by a lead nut.

[0011] To ensure the consistency of the spacing adjustment between the second supports, and thus the consistency of the wire feed angle, so as to achieve standardized production of wire insertion and welding, the preferred technical means is that there are two sets of lead screw feeding mechanisms, located at the upper and lower parts of the opposite second supports, respectively. The lead screw nuts of the two sets of lead screw feeding mechanisms are respectively fixed with sprockets on the same axis, and the two sprockets form a transmission pair through a chain.

[0012] To facilitate the arrangement of the lead screw feed mechanism, the preferred technical approach is to have the outer side of the lead screw nut rotate in conjunction with the main frame.

[0013] The main function of the linear drive mechanism is to drive the wire feeder to reciprocate. To simplify the structure and facilitate the layout, the preferred technical means is to use a cylinder located at the rear of the second support. One end of the guide shaft is connected to the power output end of the cylinder, and the other end of the guide shaft drives the wire feeder to reciprocate on the second support.

[0014] To facilitate the connection between the guide shaft and the second bracket, a preferred technical implementation is that a bushing is fixed in the middle of the guide shaft, and the outer side of the bushing is fixed to the wire feeding mechanism.

[0015] To simplify the structure and facilitate the reciprocating motion of the wire feeding frame, the preferred technical means is to provide guide grooves at the top and bottom of the second support for the reciprocating motion of the wire feeding mechanism.

[0016] To ensure the synchronous movement of the wire feeding frame and thus meet the consistency of the wire feeding stroke, so as to facilitate standardized production, the preferred technical means is that the cylinders are respectively set at the top and bottom of the rear of the second support. The top and bottom of the second support are equipped with racks, and the gears and racks respectively form a transmission pair. The gears located above and below are linked through the shaft, and the shaft rotates with the bearing sleeve fixed on the wire feeding mechanism.

[0017] The main function of the wire feeding mechanism is to complete the wire feeding under the action of the linear drive mechanism. The preferred technical means of its implementation is that the wire feeding mechanism includes a straightening wheel set on the second support for straightening the wire, a wire feeding frame driven by the linear drive mechanism to move along the guide of the second support, and a one-way wire feeder set on the wire feeding frame for conveying the wire.

[0018] The technological advancements achieved by this utility model are as follows:

[0019] 1. This utility model enables the adjustment of the wire insertion angle for core materials of different widths, meeting the processing requirements for products of different specifications, and the processed products have a wide range of applications.

[0020] 2. The structural design of the lead screw feed mechanism makes the adjustment of the spacing between the relatively set second supports more precise and flexible.

[0021] 3. The structural design of the sprocket and chain drive pair effectively ensures the synchronicity of the vertical spacing adjustment between the second supports, thereby satisfying the consistency of the wire feeding angle.

[0022] 4. A cylinder is used as the power source for the linear drive mechanism, which drives the guide shaft and bushing to move the wire feeder back and forth along the second support. The up and down movements of the wire feeder are synchronized by gears, racks and pinions, and the wire feeding action is ensured by straightening wheels and one-way wire feeders. First, the structure is simple and the operation is highly reliable. Second, it effectively ensures the accuracy and synchronization of the wire feeding angle, which is conducive to achieving standardized and rapid production. Attached Figure Description
