[0030] Embodiment

[0031] As Figures 1 to 8As shown in the figure, a powder conveying device provided by the present invention includes a frame 100, and the frame 100 is provided with a dust-free tray turning mechanism 200, a reciprocating conveying mechanism 300, and a powder fluidization mechanism 400. The dust-free tray turning mechanism 200 includes a tray turning box body 210 arranged on the frame 100 and a filtering component 220 arranged at the top end of the tray turning box body 210. Feed inlets and a discharge outlet 212 are arranged on both sides of the tray turning box body 210; the reciprocating conveying mechanism 300 includes a tray 310 and a driving component. The tray 310 is slidably arranged on the frame 100, and the driving component is used to drive the tray 310 to move back and forth along the direction close to or away from the discharge outlet 212; the powder fluidization mechanism 400 is arranged at the bottom end of the tray turning box body 210, and the powder fluidization mechanism 400 is used to suck away the powder in the tray turning box body 210.

[0032] In this embodiment, the feed inlets and the discharge outlet 212 are arranged opposite to each other. The tray 310 enters the tray turning box body 210 from the feed inlets and then leaves the tray turning box body 210 from the discharge outlet 212. Soft brushes 213 are arranged at both the feed inlets and the discharge outlet 212, and the soft brushes 213 can block the outflow of the powder in the tray turning box body 210. Two glove holes 214 are arranged on one side wall of the tray turning box body 210, and gloves are installed in the glove holes 214. After the tray 310 enters the tray turning box body 210, the worker puts his hand into the tray turning box body 210 through the glove holes 214 and pours the powder in the tray 310 to the bottom end of the tray turning box body 210.

[0033] As Figure 1 and Figure 2 As shown in the figure, the powder conveying device further includes a feeding mechanism 500 arranged on the frame 100, and the feeding mechanism 500 is located on one side of the feed inlets. Specifically, the feeding mechanism 500 is a conveyor belt, and the tray 310 filled with powder is conveyed into the tray turning box body 210 through the conveyor belt. After manual pouring, the tray 310 after pouring the powder is carried out from the discharge outlet 212 through the reciprocating conveying mechanism 300.

[0034] As Figures 2 to 4As shown, the filtering component 220 includes a filter cover 221, a filter net 222, and an adsorbing member 223. An adsorption hole 215 is provided at the top end of the inverted disk box body 210. The filter cover 221 communicates with the adsorption hole 215. The filter net 222 is arranged inside the filter cover 221. The adsorbing member 223 is connected to the filter cover 221, and the adsorbing member 223 is used to suck and blow gas to the filter net 222. Specifically, the adsorbing member 223 can be an air pump. When a large amount of powder floats in the inverted disk box body 210, the adsorbing member 223 is started to adsorb the powder on the filter net 222, avoiding a large amount of floating powder in the inverted disk box body 210. After a large amount of powder adheres to the filter net 222, the adsorbing member 223 works in the reverse direction to blow the powder on the filter net 222 down, so that the filtering component 220 can operate normally.

[0035] As Figure 3 and Figure 4 As shown, a partition plate 224 is arranged inside the filter cover 221. The partition plate 224 is provided with a plurality of mounting holes 226, and each mounting hole 226 is provided with the filter net 222. The adsorbing member 223 is located on the side of the partition plate 224 away from the inverted disk box body 210. Specifically, the filter cover 221 is cylindrical. The partition plate 224 divides the filter cover 221 into two sides. The adsorbing member 223 is located in the upper layer, and the mounting holes 226 are evenly distributed on the partition plate 224.

[0036] In this embodiment, the filter net 222 is cylindrical. The adsorbing member 223 is provided with a plurality of adsorption tubes 225. One end of the adsorption tube 225 away from the adsorbing member 223 is located inside the filter net 222. Specifically, the filter net 222 is a titanium alloy net, and the mesh holes are in the micron level. The titanium alloy net has high structural strength and is not easily damaged. The filter net 222 is cylindrical. The opening of the filter net 222 is connected to the mounting hole 226. The bottom of the filter net 222 is located in the lower layer of the filter cover 221. The cylindrical filter net 222 can increase the filtering area.

[0037] As Figure 2 , Figure 5 and Figure 6 As shown, the powder fluidization mechanism 400 includes a fluidization hopper 410 arranged at the bottom end of the inverted disk box body 210 and an air extraction pipe 420 connected to the fluidization hopper 410. The fluidization hopper 410 is large at the top and small at the bottom. The air extraction pipe 420 is used to suck away the powder falling into the fluidization hopper 410. Specifically, the fluidization hopper 410 is large at the top and small at the bottom, which is conducive to collecting the powder poured from the tray 310. The bottom of the fluidization hopper 410 is connected to the air extraction pipe 420, and the powder can be sucked away.

[0038] In this embodiment, the exhaust pipe 420 is arranged horizontally, and a long opening is provided at the top of the exhaust pipe 420, and the long opening is connected to the bottom end of the fluidizing bucket 410. This arrangement can increase the area for sucking powder and improve work efficiency.

[0039] In this embodiment, in order to prevent the powder from blocking the exhaust pipe 420, comb teeth 430 are obliquely arranged in the fluidizing bucket 410, and the comb teeth 430 are provided with a plurality of strip holes 431. Specifically, two comb teeth 430 are provided, and they are arranged in a V shape. The arrangement of the comb teeth 430 can block the falling powder and reduce the falling speed of the powder. At the same time, the arrangement of the plurality of strip holes 431 can make the powder evenly dispersed, so that the exhaust pipe 420 can extract the powder, and it also effectively reduces the situation where the powder accumulates at the bottom of the fluidizing bucket 410 and blocks the exhaust pipe 420.

[0040] In this embodiment, the side wall of the fluidizing bucket 410 is provided with an air inlet 411. Specifically, the air inlet 411 is located at the lower side of the comb teeth 430. Through the cooperation of the air inlet 411 and the strip holes 431, the air inlet 411 can form a reflux airflow, so that the powder falling into the inner cavity of the fluidizing bucket 410 flows in the reflux airflow, forming a phenomenon of powder fluidization, so that the exhaust pipe 420 can extract the powder, and effectively reduce the situation where the powder accumulates at the bottom of the fluidizing bucket 410 and blocks the exhaust pipe 420; the arrangement of the strip holes 431 allows the gas blown into the air inlet 411 to be divided into multiple streams, thereby forming multiple uniform reflux airflows to better fluidize the powder.

[0041] like Figure 7 and Figure 8 As shown, the driving assembly includes a mounting rod 321 that moves back and forth in a direction close to or away from the discharge port 212, push blocks 322 disposed at both ends of the mounting rod 321, and a driving member 323 that is transmission-connected to the mounting rod 321, wherein the push blocks 322 are used to carry the tray 310, and the driving member 323 is used to drive the mounting rod 321 to move back and forth. In this embodiment, two mounting rods 321 are provided, and the push blocks 322 are disposed at both ends of the two mounting rods 321. The two mounting rods are connected by a synchronous shaft 3211. Specifically, the mounting rod 321 is disposed in a direction from the feed port to the discharge port 212, and the travel of the mounting rod 321 is greater than the distance from the feed port to the discharge port 212.

[0042] In this embodiment, fixing seats 324 are provided at both ends of the mounting rod 321. The push block 322 is hinged to the fixing seat 324. A return spring 325 is provided between the fixing seat 324 and the push block 322. When the return spring 325 is in its natural state, the push block 322 is in a vertical state. Through the structural design of the fixing seat 324 and the push block 322, the push block 322 is in a perpendicular state to the fixing seat 324 when pushing the tray 310. When the push block 322 is driven back to its original position by the driving member 323, under the gravity of the tray 310, the push block 322 abuts against the edge of the tray 310 and gradually flips towards the bottom of the tray 310, so that the push block 322 disengages from the tray 310 and resets to its original position, and is reset by the return spring 325, so that the pushing mechanism that returns to its original position returns to the state of originally pushing the tray 310.

[0043] As Figure 7 and Figure 8 shown, the mounting rod 321 is vertically connected with a connecting rod 326. The connecting rod 326 extends out of one side in the width direction of the tipping box body 210. The connecting rod 326 is connected with a connecting plate 327. The driving member 323 is a motor. A first pulley 328 is provided on the output shaft of the motor. A second pulley 329 is provided on the frame 100. A driving belt 330 is provided between the first pulley 328 and the second pulley 329. The connecting plate 327 is fixed on the driving belt 330. When the motor rotates forward and backward, the mounting rod 321 can be driven to move back and forth.

[0044] Working principle:

[0045] The tray 310 filled with powder is transported into the tipping box body 210 through the conveyor belt. After manual dumping, the reciprocating conveying mechanism 300 is used to carry out the tray 310 with the powder dumped from the discharge port 212;

[0046] When a large amount of powder floats in the tipping box body 210, the adsorbing member 223 is started to adsorb the powder on the filter screen 222, so as to avoid a large amount of floating powder in the tipping box body 210; after a large amount of powder adheres to the filter screen 222, the adsorbing member 223 works in the reverse direction to blow the powder on the filter screen 222 down, so that the filtering assembly 220 can operate normally;

[0047] The fluidizing hopper 410 collects the powder poured from the tray 310. The bottom of the fluidizing hopper 410 is connected with an air extraction pipe 420, which can extract the powder.

[0048] In summary, the powder conveying device adopts a dust-free turnover mechanism 200, which can effectively filter the powder suspended in the turnover box body 210. The reciprocating conveying mechanism 300 can improve the efficiency of the handling tray 310. The powder fluidization mechanism 400 can quickly suck away the powder in the turnover box body 210, improving the powder handling efficiency, reducing dust pollution at the same time, and reducing the safety hazard of dust explosion.

[0049] The above embodiments are preferred implementation solutions of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present invention.
