In order to further optimize the feeding process of powder raw materials, so that the powder can be fed continuously and evenly, and avoid the agglomeration and agglomeration of the powder, a feeding system is proposed.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a unloading system, comprising a transfer box, a unloading barrel and a pneumatic unloading mechanism, the pneumatic unloading mechanism comprising an air pump fixedly connected to the bottom surface of the transfer box, four air supply ports being installed on the surface of the unloading barrel, the four air supply ports being symmetrical in pairs and located at different heights, the output end of the air pump being connected to an air supply pipe, and the air supply pipe being respectively connected to the four air supply ports.

[0007] An auxiliary unloading mechanism is provided inside the transfer box, and the auxiliary unloading mechanism includes a first spiral blade and a second spiral blade rotatably sleeved on the inner wall of the transfer box.

[0008] Through the above scheme, the air pump is started to deliver the gas to the air delivery pipe, and the gas is delivered to the inside of the discharge barrel from four directions through the four air delivery ports. The height difference and symmetrical design between the four air delivery ports can form a swirl airflow, which produces a continuous and uniform powder flow in the discharge barrel, avoiding the agglomeration and agglomeration of the raw materials.

[0031] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0032] See also Figure 1 、 Figure 3 and Figure 4 , a unloading system in this embodiment includes a transfer box 1, a unloading barrel 2 and a pneumatic unloading mechanism 3. The four corners of the transfer box 1 are provided with evenly distributed positioning bolts 6 and positioning bolts 2 7. The transfer box 1 and the unloading barrel 2 are connected by several positioning bolts 1 6 and positioning bolts 2 7. By setting the positioning bolts 1 6 and positioning bolts 2 7, the transfer box 1 and the unloading barrel 2 can be stably connected. At the same time, it is also convenient for the disassembly work between the transfer box 1 and the unloading barrel 2, and it is convenient for regular maintenance work. The bottom of the unloading barrel 2 is connected to the interior of the transfer box 1, so that the raw materials in the unloading barrel 2 can fall into the transfer box 1 for unloading.

[0033] See also Figure 2 、 Figure 3 and Figure 4The pneumatic unloading mechanism 3 includes an air pump 301 fixedly connected to the bottom surface of the transfer box 1, and four air supply ports 302 are installed on the surface of the unloading barrel 2. The four air supply ports 302 are symmetrical in pairs and located at different heights. The output end of the air pump 301 is connected to an air supply pipe 303, and the air supply pipe 303 is respectively connected to the four air supply ports 302. When the air pump 301 is started, gas will be transported through the air supply pipe 303, and the gas in the air supply pipe 303 will be transported to the inside of the unloading barrel 2 through the four air supply ports 302. In this way, the gas can enter the inside of the unloading barrel 2 from four directions at different heights through the four air supply ports 302, and each air supply port 3 02 and the symmetrical design can form a swirl airflow, which produces a continuous and uniform powder flow in the discharge barrel 2, effectively reducing the probability of raw material agglomeration, so that the raw materials can be evenly dispersed and discharged. The outer surface of the transfer box 1 is fixedly connected to the first guide frame 304, and the outer surface of the discharge barrel 2 is fixedly connected to the second guide frame 305. The output end of the air supply pipe 303 passes through the first guide frame 304 and the second guide frame 305 in sequence. By setting the first guide frame 304 and the second guide frame 305, the air supply pipe 303 can be guided to avoid the air supply pipe 303 from being scattered at will and interfering with the movement of other components.

[0034] See also Figure 2 、 Figure 3 and Figure 4 The interior of the transfer box 1 is provided with an auxiliary unloading mechanism 4, which includes a first spiral blade 401 and a second spiral blade 403 which are rotatably sleeved on the inner wall of the transfer box 1. The outer surface of the transfer box 1 is respectively provided with a first feeding pipe 402 corresponding to the first spiral blade 401 and a second feeding pipe 404 corresponding to the second spiral blade 403. The first feeding pipe 402 and the second feeding pipe 404 are both provided with an electromagnetic valve 405. The first feeding pipe 402 and the second feeding pipe 404 are both connected to the interior of the transfer box 1. By setting up the solenoid valve 405, the flow inside the first feeding pipe 402 and the second feeding pipe 404 can be controlled, which facilitates the precise feeding work. When the first spiral blade 401 rotates, the raw materials inside the transfer box 1 can be transported through the first feeding pipe 402. When the second spiral blade 403 rotates, the raw materials inside the transfer box 1 can be transported through the second feeding pipe 404. The work of feeding the powder raw materials through the first spiral blade 401 and the second spiral blade 403 can further prevent the raw materials from agglomerating and clumping.

[0035] See also Figure 1 、 Figure 2 and Figure 4The first spiral blade 401 and the second spiral blade 403 are provided with a driving mechanism 5 at the rotating shaft end. The driving mechanism 5 includes a servo motor 501 fixedly connected to both sides of the outer surface of the transfer box 1. The output shaft end of each servo motor 501 is fixedly connected to a driving sprocket 502. By setting the servo motor 501, power can be provided for the rotation of the driving sprocket 502. The rotating shaft end of the first spiral blade 401 is fixedly connected to a first driven sprocket 503. A first chain 505 is provided on the outside of the first driven sprocket 503. The first driven sprocket 503 is transmission-connected to the corresponding driving sprocket 502 through the first chain 505. When the corresponding driving sprocket 502 rotates, the first driven sprocket 503 can be driven to rotate by the first chain 505. The rotation of the first driven sprocket 503 can make the first spiral blade 401 rotate, and then the powder raw material can be transported to the outside through the first feeding pipe 402 through the rotation of the first spiral blade 401. The rotating shaft end of the second spiral blade 403 is fixedly connected to the second driven sprocket 504. The second driven sprocket 504 is provided on the outside of the second driven sprocket 504. The second driven sprocket 504 is connected to the corresponding driving sprocket 502 through the second chain 506. When the corresponding driving sprocket 502 rotates, the second driven sprocket 504 can be driven to rotate by the set second chain 506. When the second driven sprocket 504 rotates, it can drive the second spiral blade 403 to rotate, and then the powder raw material can be transported to the outside through the second feeding pipe 404.

[0036] It should be noted that, in a feeding system, by starting the air pump 301, the gas can be delivered to the air supply pipe 303, and the air can be delivered to the inside of the feeding barrel 2 from four directions through four evenly distributed air supply ports 302. The design of the four air supply ports 302 not only takes into account the height difference and symmetrical layout, but also can form a swirl airflow, promote continuous and uniform powder flow inside the feeding barrel 2, and effectively prevent the raw materials from agglomerating and agglomerating. In addition, through the operation of the driving mechanism 5, the first spiral blade 401 and the second spiral blade 403 can be driven to rotate. The rotation of these two spiral blades can not only further prevent the raw materials from agglomerating and agglomerating, but also can deliver the raw materials to other feeding barrels through the first feeding pipe 402 or the second feeding pipe 404.

[0037] The working principle of the above embodiment is as follows: when in use, the air pump 301 can be started to generate gas, and the generated gas will be transported through the air supply pipe 303, and the gas in the air supply pipe 303 will be input into the discharge barrel 2 through the four air supply ports 302. Since there is a height difference between the four air supply ports 302, the gas can enter the interior of the discharge barrel 2 from four directions at different heights through the four air supply ports 302. The height difference and symmetrical design between the air supply ports 302 can form a swirl airflow, which produces a continuous and uniform powder flow in the discharge barrel 2, effectively reducing the probability of raw material agglomeration, so that the raw material can be evenly dispersed for discharge. When it is necessary to discharge through the first feeding pipe 402, the corresponding solenoid valve 405 can be opened first and the second feeding pipe can be opened. The solenoid valve 405 in the material pipe 404 is in a closed state, and the corresponding servo motor 501 is started. When the corresponding servo motor 501 is started, it will drive the driving sprocket 502 to rotate and drive the first driven sprocket 503 to rotate through the first chain 505. When the first driven sprocket 503 rotates, it will drive the first spiral blade 401 to rotate. The rotation of the first spiral blade 401 can avoid the agglomeration of raw materials and ensure the normal feeding of raw materials. Similarly, when it is necessary to feed through the second feeding pipe 404, the solenoid valve 405 in the first feeding pipe 402 should be closed and the solenoid valve 405 in the second feeding pipe 404 should be opened, and then the corresponding servo motor 501 should be started, so that the raw materials can be fed through the rotation of the second spiral blade 403.
