[0002] Welding electrodes consist of two parts: the core and the coating. The coating is applied evenly and concentrically to the metal core. Different types of welding electrodes have different cores. The core is the metal part of the electrode. To ensure the quality and performance of the weld, the coating is a layer of paint applied to the surface of the core. Its main function is to improve welding process performance and ensure weld quality. Its components include arc stabilizers, slag builders, deoxidizers, gas builders, slag thinners, alloying agents, and binders.

[0003] Currently, in existing technologies, the electrode coating is adhered to the core of the welding rod using an adhesive. This process is mostly done manually, and the adhesive needs to dry before the coating can be applied again, resulting in high work efficiency and increased manual labor. Therefore, this invention proposes a device for applying electrode coating to welding rods. Summary of the Invention

[0004] The purpose of this invention is to solve the problem in the prior art where the electrode coating is adhered to the core wire with an adhesive. This process is mostly done manually, and the adhesive needs to dry before the coating can be applied again, which results in a lot of wasted work and increased manual labor.

[0006] The wrapping mechanism includes a fixed bracket, which is disposed on the outside of the support base. A side slide plate is fixedly connected to the inner side wall of the fixed bracket. The fixed bracket is slidably installed in the side limiting groove through the side slide plate. Several evenly distributed pulleys are rotatably installed on both sides of the lower surface of the fixed bracket.

Detailed Implementation

[0017] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0019] In existing technology, welding electrodes consist of two parts: the core and the coating. The coating is applied evenly and concentrically to the metal core. Different types of welding electrodes have different cores. The core is the metal part of the electrode. To ensure the quality and performance of the weld, the coating is a layer applied to the surface of the core. Its main function is to improve welding process performance and ensure weld quality. Its components include arc stabilizers, slag generators, deoxidizers, gas generators, slag thinners, alloying agents, and binders. The coating is then adhered to the core using an adhesive. This process is mostly done manually, as the adhesive needs to dry before a second coating can be applied, resulting in high work efficiency and increased labor costs.

[0020] Therefore, the objective of this invention is at least as follows: The welding rod is placed in the mounting groove 214, and the second electric actuator 306 is activated to drive the lifting plate 305 to rise and fall. The lifting plate 305, through the linkage of the side connecting rod 304, can pull the side plate 307 to move synchronously. The side plate 307 will move horizontally along the side sliding groove 211 via the side slider 303. The welding rod is fixed in the mounting groove 214 by the side clamping plate 301. Then, the electric actuator 212 is activated to drive the fixing bracket 202 to move horizontally along the limiting groove 102. Subsequently, the upper toothed plate 203 on the upper surface of the fixing bracket 202 meshes with the driven gear 205, which drives the transmission rod 206 to rotate around the driven gear 205. This allows the transmission rod 206 to drive the loading plate 209 and the unloading plate 104 to overlap outside the welding rod, thereby achieving the fixation of the outer coating of the welding rod.

[0021] Implementation examples, based on Figures 1-7 An embodiment of the present invention provides a device for coating welding rods, comprising a support mechanism 100, a coating mechanism 200 mounted on the support mechanism 100, and a positioning mechanism 300 mounted on the support mechanism 100; as shown Figure 3 As shown, the support mechanism 100 includes a fixed seat 103, a feeding plate 104 is fixedly connected to the upper surface of the fixed seat 103, a support seat 101 is fixedly connected to the lower surface of the fixed seat 103, and side limiting grooves 102 are opened on both sides of the support seat 101.

[0022] like Figure 4As shown, the wrapping mechanism 200 includes a fixed bracket 202, which is disposed on the outside of the support base 101. A side slide plate 201 is fixedly connected to the inner wall of the fixed bracket 202. The fixed bracket 202 is slidably installed in the side limiting groove 102 via the side slide plate 201. Several evenly distributed pulleys 213 are rotatably installed on both sides of the lower surface of the fixed bracket 202. An upper toothed plate 203 is fixedly connected to the upper surface of the fixed bracket 202. A driven gear 205 is meshed above the upper toothed plate 203. A central shaft 204 is fixedly connected to the center of each driven gear 205. Each central shaft 204 is rotatably installed on the outer wall of the fixed base 103. A transmission rod 206 is fixedly connected to the outside of each central shaft 204. A connecting piece 207 is fixedly connected to the upper end of the transmission rod 206. A connecting side plate 208 is rotatably installed on the inner side of the connecting piece 207. A feeding plate 209 is fixedly connected to the inner side of the side plate 208. The feeding plate 209 is located above the unloading plate 104. A mounting sheet metal 210 is fixedly connected to one side of the upper surface of the fixed bracket 202. The upper end of the mounting sheet metal 210 has a mounting groove 214. The lower end of the mounting sheet metal 210 has side sliding grooves 211 on both sides. An electric push rod 212 is fixedly connected to one side surface of the mounting sheet metal 210. The electric push rod 212 is fixedly connected to one end of the fixed base 103. When the electric push rod 212 is started, the fixed bracket 202 can be moved horizontally along the limiting groove 102. Then, the upper toothed plate 203 on the upper surface of the fixed bracket 202 and the driven gear 205 mesh, which can drive the transmission rod 206 to rotate around the driven gear 205. Thus, the feeding plate 209 and the unloading plate 104 are aligned outside the welding rod through the transmission rod 206, thereby fixing the outer coating of the welding rod.

[0023] like Figure 7 As shown, the positioning mechanism 300 includes two side clamps 301, which are disposed on both sides inside the mounting groove 214. Side plates 307 are fixedly connected to the outer walls of the two side clamps 301, located on both sides of the mounting sheet metal 210. Side sliders 303 are fixedly connected to the inner walls of the side plates 307, allowing the side plates 307 to slide within the side sliding groove 211 via the side sliders 303. A rotating seat 302 is fixedly connected to the inner wall of the side plate 307, allowing the rotating seat 302 to rotate within the groove. A side connecting rod 304 is rotatably installed, and a lifting plate 305 is rotatably installed at the lower end of the side connecting rod 304. A second electric actuator 306 is fixedly connected to the lower surface of the lifting plate 305. The second electric actuator 306 is fixedly connected to the upper surface of the fixed bracket 202. When the welding rod is placed in the mounting groove 214, the second electric actuator 306 is activated to drive the lifting plate 305 to rise and fall. The lifting plate 305 can pull the side plate 307 to move synchronously through the linkage of the side connecting rod 304. The side plate 307 will move horizontally along the side sliding groove 211 through the side slider 303. The welding rod is fixed in the mounting groove 214 by the side clamping plate 301.

[0024] The working principle of this invention is as follows: First, the welding rod is placed in the mounting groove 214, and the second electric push rod 306 is started to drive the lifting plate 305 to rise and fall. The lifting plate 305, through the linkage of the side connecting rod 304, can pull the side plate 307 to move synchronously. The side plate 307 will move horizontally along the side sliding groove 211 through the side slider 303. The welding rod is fixed in the mounting groove 214 by the side clamping plate 301. Then, the electric push rod 212 is started to drive the fixed bracket 202 to move horizontally along the limiting groove 102. Then, the upper toothed plate 203 on the upper surface of the fixed bracket 202 and the driven gear 205 mesh, which can drive the transmission rod 206 to rotate around the driven gear 205. The transmission rod 206 can drive the loading plate 209 and the unloading plate 104 to coincide outside the welding rod, thereby fixing the outer coating of the welding rod.
