DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0018] Please refer to Figures 1-5 The present application provides a technical solution: a metal powder automatic feeding device, comprising a feeding frame 1 and an anti-blocking mechanism 2 and a buffer mechanism 5 both mounted on the upper end of the feeding frame 1.

[0019] The anti-blocking mechanism 2 comprises a feeding pipe 201 mounted on one side of the top of the feeding frame 1. The top of the feeding frame 1 is provided with a feeding groove 202 on one side, and the inner wall of the feeding groove 202 is in communication with the inner wall of the feeding pipe 201. A support frame 203 is mounted on one side of the top of the feeding frame 1, one end of the support frame 203 is provided with a first electric telescopic rod 204, the output end of the first electric telescopic rod 204 is provided with an extension frame 205, one end of the extension frame 205 is provided with a second electric telescopic rod 206, the output end of the second electric telescopic rod 206 is provided with a mounting cover 207, the inside of the mounting cover 207 is provided with a motor 208, the bottom of the mounting cover 207 is connected with a dredging drill bit 209, and one end of the dredging drill bit 209 is fixedly connected with the output end of the motor 208.

[0020] When in use, the block-shaped metal raw material used by the metal powder processing is transmitted to the chute 501 through the conveying belt 4, and falls into the feeding chute 202 along with the chute 501, and then is introduced into the feeding pipe 201 through the feeding chute 202, and the feeding operation can be performed by opening the sealing valve 211. In this process, the block-shaped raw material may be squeezed and blocked in the feeding pipe 201 due to irregularity. At this time, the first electric telescopic rod 204 is started to push the extension frame 205 to move, so that the dredging drill bit 209 moves directly below the feeding pipe 201, and then the second electric telescopic rod 206 and the motor 208 are started to make the dredging drill bit 209 rotate and extend into the feeding pipe 201, so as to stir the metal raw material in the feeding pipe 201, so that the metal raw material is dredged, and then the dredging drill bit 209 is retracted and the first electric telescopic rod 204 is retracted to move the mechanism to the outer edge of the feeding pipe 201, without affecting the normal feeding of the feeding pipe 201, thereby solving the problem that the metal powder raw material is easily blocked frequently during the feeding process, affecting the metal powder processing efficiency.

[0021] Further, the limit stop 210 is installed at the edge of the bottom of the feeding pipe 201, and the sealing valve 211 is installed on one side of the feeding pipe 201. The limit stop 210 on one side of the feeding pipe 201 limits the installation cover 207, so that the extension frame 205 does not move excessively, so that the dredging drill bit 209 can accurately enter the feeding pipe 201 to dredge the raw material, and the sealing valve 211 is used to control the opening and closing of the feeding pipe 201.

[0022] Further, the installation groove 3 is formed on the other side of the top of the feeding frame 1, and the conveying belt 4 is installed in the installation groove 3. During feeding, the raw material is transmitted by the conveying belt 4.

[0023] Further, the buffer mechanism 5 comprises the chute 501 formed on one side of the top of the feeding frame 1, and the inner wall of one end of the chute 501 is in communication with the inner wall of the feeding chute 202. The guide chute 502 is installed on both sides of the inner wall of the chute 501.

[0024] The buffer groove 503 is formed on one side of the chute 501, the buffer plate 504 is rotatably connected to one side of the inner wall of the buffer groove 503, a plurality of springs 505 are fixedly arranged at the bottom of the inner wall of the buffer groove 503 at equal intervals, and one end of each spring 505 is fixedly connected to the bottom of the buffer plate 504. During feeding, the raw material is transmitted to the chute 501 through the conveying belt 4, and is guided by the guide chute 502 on both sides to be centered and transmitted, so as to be accurately dropped into the feeding chute 202. During the falling process, the raw material is pressed on the buffer plate 504 and the spring 505 is compressed in the buffer groove 503, so as to reduce the falling speed of the raw material in the chute 501 and reduce the damage caused by the impact of the raw material on the equipment. At the same time, it can also prevent the raw material from splashing out of the equipment and causing loss.
