Description

Technical Field

[0001] This utility model belongs to the field of plastic welding technology, and specifically relates to an extrusion-type plastic welding gun wire feeder. Background Technology

[0002] Extrusion-type plastic welding guns utilize hot air heating and screw extrusion technology to weld plastic materials through a mechanical structure. During the welding process, a continuous supply of welding wire is required to the gun. Current technologies typically involve simply unwinding a roll of welding wire before welding, resulting in a messy, scattered mess on-site that can interfere with other construction activities. Utility Model Content

[0003] In view of this, the purpose of this utility model is to address the shortcomings of the existing technology by providing an extrusion-type plastic welding gun wire feeder to ensure orderly wire feeding during the welding process.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An extrusion-type plastic welding gun wire feeder includes a base plate, a vertical shaft, a support plate, a sleeve, and a bearing. The vertical shaft is vertically mounted on the base plate. The support plate is fixedly sleeved on the bottom outer side of the sleeve. The sleeve is sleeved on the outside of the vertical shaft, and the sleeve and the vertical shaft are rotatably connected by a bearing. There is a movable gap between the support plate and the base plate.

[0006] To better realize this utility model, the above structure is further optimized by providing two bearings, which are respectively located at the top and bottom of the sleeve.

[0007] To better realize this utility model, the above structure is further optimized, and the bearing adopts a deep groove ball bearing or a tapered roller bearing.

[0008] To better realize this utility model, the above structure is further optimized. Both the base plate and the support plate are disc structures, and the diameter of the support plate is smaller than the diameter of the base plate.

[0009] To better realize this utility model, the above structure is further optimized, and the vertical shaft is fixedly set at the center of the base plate.

[0010] To better realize this utility model, the above structure is further optimized, and the base plate and support plate are made of PP board.

[0011] To better realize this utility model, the above structure has been further optimized, and both the vertical shaft and the sleeve are made of PP material.

[0012] Compared with the prior art, this utility model has the following advantages:

[0013] The extrusion-type plastic welding gun wire feeder provided by this utility model allows a roll of welding wire to be directly sleeved on the sleeve. The power of the welding gun when feeding the wire drives the sleeve to rotate around the vertical axis to feed the wire, ensuring orderly wire feeding during the welding process, keeping the construction site clean, and not hindering the operation of other processes.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0022] like Figure 1 and Figure 2 As shown, the extrusion-type plastic welding gun wire feeder provided in this application includes a base plate 1, a vertical shaft 2, a support plate 3, a sleeve 4, and a bearing 5. The vertical shaft 2 is vertically mounted on the base plate 1. The vertical shaft 2 and the base plate 1 form the support part. The support plate 3 is fixedly sleeved on the bottom outer side of the sleeve 4. The sleeve 4 is sleeved on the outside of the vertical shaft 2. The sleeve 4 and the support plate 3 form the rotating part. In use, a roll of welding wire is passed through the sleeve 4 from above and placed on the support plate 3. The power of the welding gun when feeding the wire drives the sleeve 4 to rotate around the vertical shaft 2 to feed the wire, ensuring orderly wire feeding during the welding process. The sleeve 4 and the vertical shaft 2 are rotatably connected by the bearing 5. There is a movable gap between the support plate 3 and the base plate 1. The support plate 3 rotates with the sleeve 4 without interfering with the base plate 1 below. In actual use, if the mass of the welding wire is large, a thrust bearing for bearing axial load can be set between the support plate 3 and the base plate 1.

[0023] Two bearings 5 ​​are provided, one at the top and one at the bottom of the sleeve 4. Both ends of the sleeve 4 have stable supports, making the rotation between the sleeve 4 and the vertical shaft 2 smoother. In this device, the bearings 5 ​​mainly bear radial loads, and also need to bear the axial load exerted by the weight of the welding wire itself. Since the welding wire is made of plastic and is lightweight, it only needs to bear a small portion of the axial load due to gravity during actual operation, making most bearings suitable. Preferably, the bearings 5 ​​can be deep groove ball bearings or tapered roller bearings, mainly bearing radial loads while also bearing a portion of the axial load. In this embodiment, the two bearings 5 ​​are deep groove ball bearings 6004.

[0024] Both the base plate 1 and the support plate 3 are disc structures with a thickness of 30mm. The diameter of the support plate 3 is smaller than that of the base plate 1. The diameter of the support plate 3 is 340mm, and the diameter of the base plate 1 is 500mm.

[0025] The vertical shaft 2 is fixedly set at the center of the base plate 1. The diameter of the vertical shaft 2 is 20mm, and the height from the top of the vertical shaft 2 to the bottom of the base plate 1 is 207mm.

[0026] For ease of material sourcing and manufacturing, the base plate 1 and support plate 3 are made of PP board. The vertical shaft 2 and sleeve 4 are also made of PP material. The top of sleeve 4 is flush with the top of vertical shaft 2, the height from the top of sleeve 4 to the top surface of support plate 3 is 142mm, and the outer diameter of sleeve 4 is 48mm. The width of the movable gap between support plate 3 and base plate 1 is 5mm. By lowering the center of gravity of the entire device through the base plate 1 and support plate 3 at the bottom, tipping over during operation can be effectively prevented.

[0027] When in use, place the device stably on the ground and pass a coil of welding wire through the sleeve 4 and place it on the support plate 3. When connecting the welding wire to the welding gun for welding operations, the power of the welding gun feeding the wire will cause the welding wire to rotate around the vertical axis 2 to feed the wire. Moreover, since the top of the wire feeder has an open structure, it can effectively avoid interference and friction between the welding wire and the device when working at height, ensuring smooth and reliable rotation.

[0028] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
