[0023] Further, one side of the surface of the rubber pad 406 is attached to the ramming plate 405. Four sets of second springs 404 are provided. With the arrangement of the second springs 404 and the rubber pad 406, during use, the second springs 404 and the rubber pad 406 can cause the ramming plate 405 to vibrate during ramming, increasing the ramming effect and also playing a certain buffering and protective role.

[0024] Further, the ramming plate 405 is fitted inside the powder chamber 7. One side of the surface of the ramming plate 405 is in line with the size of the powder chamber 7. The push plate 403 is fitted inside the powder chamber 7.

When in use, when applying pressure to the welding rod, firstly, one end of the welding rod to be applied is passed through the mounting hole 309, and is clamped by the clamping device 310, and then the cylinder 301 is started, and one end of the cylinder 301 drives the connecting plate 303 to move, and then the connecting plate 303 drives the connecting shell 307 to move through the telescopic block 305 and the first spring 306, and at the same time, the connecting shell 307 drives the stabilizing block 304 moves horizontally along one end of the stabilizing rod 302, and then the connecting shell 307 drives one end of the welding rod clamped by the clamping device 310 to penetrate into the inlet hole 5, and then the powder inside the powder chamber 7 continuously adheres to the surface of the welding rod under the action of pressure. After the adhesion is completed, the first electric telescopic rod 308 is started, and one end of the first electric telescopic rod 308 drives the top plate 311 and the top rod 312 to move, and the top rod 312 pushes one end of the welding rod to make it detach from the clamping device 310, and then the welding rod with the powder adhered is squeezed out at the extrusion die hole 6 to form a powder-coated welding rod.

[0026] Furthermore, one end of the push rod 312 is embedded in the inside of the mounting hole 309, and one end of the push rod 312 is consistent with the size of the mounting hole 309. Through the setting of the push rod 312, when in use, the push rod 312 is used to push the welding rod to make it disengage from the clamping device 310.

[0027] Furthermore, one side of the surface of the stabilizing block 304 is connected to the connecting shell 307. One end of the first electric telescopic rod 308 passes through the connecting shell 307 and is connected to the top plate 311. Through the settings of the stabilizing block 304 and the top plate 311, during use, the stabilizing block 304 cooperates with the stabilizing rod 302 to ensure the smooth movement of the connecting shell 307. The top plate 311 is used to transmit the force of the first electric telescopic rod 308 to drive the ejector rod 312 to move.

[0028] Furthermore, one end of the telescopic block 305 passes through the first spring 306 and is connected to the connecting shell 307. There are two groups of stabilizing blocks 304. Through the setting of the first spring 306, during use, the first spring 306 plays a role in buffering and resetting, which helps to smoothly transmit power.

[0029] Working principle: First, when ramming the medicinal powder, after the welding rod passes through the inlet hole 5, the medicinal powder continuously enters the powder chamber 7 from the feeding port 402 and is squeezed in. Then, the second electric telescopic rod 401 is started. One end of the second electric telescopic rod 401 extends and drives the push plate 403 to move along the inside of the powder chamber 7. After that, the push plate 403 drives the ramming plate 405 to beat the powder inside the powder chamber 7 through the second spring 404, ensuring the tightness between the powders and ramming the powders. The rubber pad 406 on the surface of the ramming plate 405 can make the ramming plate 405 have a certain vibration when beating. At the same time, in cooperation with the second spring 404, it repeatedly contracts and then releases its elasticity, pushing the ramming plate 405 to vibrate back and forth further, so that the effect of ramming the powders is further enhanced. Then, when coating the welding rod, first, one end of the welding rod to be coated is inserted into the mounting hole 309 and is clamped by the clamping device 310. Then, the cylinder 301 is started. One end of the cylinder 301 drives the connecting plate 303 to move. Subsequently, the connecting plate 303 drives the connecting shell 307 to move through the telescopic block 305 and the first spring 306. At the same time, the connecting shell 307 drives the stabilizing block 304 to move horizontally along one end of the stabilizing rod 302. After that, the connecting shell 307 drives one end of the welding rod clamped by the clamping device 310 to pass through the inlet hole 5. Then, the medicinal powder inside the powder chamber 7 continuously adheres to the surface of the welding rod under the action of pressure. After the adhesion is completed, the first electric telescopic rod 308 is started. One end of the first electric telescopic rod 308 drives the top plate 311 and the ejector rod 312 to move. By pushing the end of the welding rod with the ejector rod 312, it makes the welding rod break away from the clamping device 310. Subsequently, the welding rod with adhered medicinal powder is extruded at the extrusion die hole 6 to form a coated welding rod.
