[0053] Reference Figures 1 to 3 , an embodiment of the present application provides a feeding system, the feeding system includes a storage component, a feeding component, a feeding component 30 and a controller. Figure 2The material storage component includes a material storage tank 11, a first material discharge valve 12 and a first material level meter 13. The bottom of the material storage tank 11 is provided with a first material discharge valve 12 and a first material level meter 13 from bottom to top. The first material level meter 13 is used to detect the low level of the material.

[0054] The feeding assembly includes a feeding tank 21, a first feeding valve 22, a first negative pressure suction assembly 23 and a first vacuum valve 234. The number of the storage tank 11, the feeding tank 21 and the feeding assembly 30 is at least two and together form a material group. In the same material group, each feeding tank 21 supplies materials to all storage tanks 11 at least through the first pipeline 210. The first pipeline 210 can be set to a main and branch structure. Exemplarily, one outlet end of the first pipeline 210 is connected to the storage tank 11, and the other outlet end of the first pipeline 210 can be connected to the feeding tank 21 or not. Exemplarily, the material can include polymer pellets, powders or a mixture of polymer pellets, powders and additive pellets. Each feeding tank 21 is correspondingly provided with a first feeding valve 22 installed on the first pipeline 210. Exemplarily, the first feeding valve 22 can be installed on the corresponding branch. By opening or closing the first supply valve 22, the process of supplying materials from the supply tank 21 to the storage tank 11 can be opened or blocked. The first negative pressure suction assembly 23 is connected to each storage tank 11 through the second pipeline 230. Exemplarily, the first negative pressure suction assembly 23 can be connected to the top of the storage tank 11. When the first negative pressure suction assembly 23 is working, it can generate negative pressure in the storage tank 11, so that under the action of negative pressure, the material can flow into the storage tank 11 through the first pipeline 210 to complete the storage operation. Exemplarily, the pipeline connected to the first negative pressure suction assembly 23 can be set as a main road and multiple branches connected to each other, and the branches are connected to the corresponding storage tanks 11. The corresponding valves can be installed in the corresponding branches, and each storage tank 11 is correspondingly provided with a first vacuum valve 234 installed in the second pipeline 230. The vacuum operation of the storage tank 11 can be started or stopped by opening or closing the first vacuum valve 234.

[0055] In this embodiment, a plurality of storage tanks 11, a plurality of supply tanks 21 and a plurality of feeding components 30 form two material groups. Due to space limitations, the storage tanks 11 and feeding components 30 of the other material group are simplified. The connection method of the simplified storage tanks 11 and feeding components 30 is the same as the connection method of the corresponding components shown in the figure.

[0056] The feeding assembly 30 includes a feeding bin 31, a feeding member 32 and a weighing sensor 33. The feeding bin 31 is arranged at the bottom side of the storage tank 11 to receive the output material of the storage tank 11. The feeding member 32 is arranged at the bottom of the feeding bin 31. The feeding member 32 includes a first driving member 321 and a screw 322 connected to each other. The first driving member 321 is used to drive the screw 322 to rotate to send the material out of the feeding bin 31. Specifically, the first driving member 321 drives the screw 322 to rotate to bring the material out along the thread direction of the screw 322. Exemplarily, the first driving member 321 may include a motor. The feeding bin 31 is carried by the weighing sensor 33.

[0057] The controller is used to calculate the feeding speed of the feeding bin 31 according to the feeding weight loss signal output by the weighing sensor 33 and control the first driving member 321 to adjust the feeding speed of the feeding bin 31 to match the preset feeding speed. When the material weight fed back by the weighing sensor 33 is lower than the lower limit of the material weight preset by the controller, the controller is also used to control the first unloading valve 12 according to the output signal of the weighing sensor 33 to adjust the storage tank 11 to replenish the feeding bin 31 until the material weight fed back by the weighing sensor 33 rises to the preset upper limit of the material weight. The controller is also used to stop calculating the feeding speed when the feeding bin 31 is replenished until the feeding bin 31 is replenished. Specifically, when the feeding bin 31 is replenished, the controller will temporarily stop calculating the weight loss of the feeding bin 31 per unit time to ensure the accuracy of the feeding amount. When the feeding bin 31 is replenished, the controller recalculates the feeding speed to further ensure the feeding accuracy. The controller is also used to control the opening of the first feeding valve 22 and the first vacuum valve 234 according to the output signal of the first material level meter 13 to perform the material suction operation, so as to ensure that there is sufficient material capacity in the storage tank 11, which is conducive to further ensuring the continuity of the feeding system to further improve the feeding efficiency. Exemplarily, the controller can close the first vacuum valve 234 after the preset material suction time, thereby stopping the material suction operation. Specifically, when the material weight fed back by the weighing sensor 33 is lower than the lower limit of the material weight preset by the controller, the controller controls the first unloading valve 12 to regulate the storage tank 11 to replenish the material to the feeding bin 31. When the material capacity of the storage tank 11 drops to the first material level meter 13, it means that there is less material in the storage tank 11. At this time, the controller controls the opening of the first feeding valve 22 and the first vacuum valve 234 to perform the material replenishment operation in the storage tank 11. The controller is also used to control the corresponding speed sequence of different feeding components 30 to replenish materials in sequence according to the speed sequence of the feeding speed, so that timely replenishment between multiple feeding routes can be achieved. Specifically, when the feeding speed output by the weighing sensor 33 of the corresponding feeding component 30 is relatively fast, the controller controls the unloading valve, feeding valve, and vacuum valve on the corresponding feeding route to start the replenishment operation, and the unloading valve, feeding valve, and vacuum valve on other feeding routes can be closed. The controller regulates the replenishment sequence of different feeding routes according to the speed sequence of the feeding speed, which is conducive to improving the continuity of replenishment, thereby further improving the feeding rate, and the coordination of the controller and the feeding speed enables the first negative pressure suction component 23 to quickly and timely regulate multiple feeding routes for replenishment, which is also conducive to improving the energy efficiency of the feeding system, and then helping to reduce production costs. In addition, the coordination of multiple storage tanks 11, multiple feeding tanks 21, and multiple feeding components 30 is also conducive to improving the feeding load per unit time of the feeding system, thereby also facilitating further improving the feeding efficiency.

[0058] It is understandable that the controller is electrically connected to the weighing sensor 33, the first driving member 321, the first discharge valve 12, and the first material level meter 13. For example, the controller can be a PLC controller. Specifically, the preset feeding speed of the first driving member 321 can be set in the controller program. The controller calculates the value of the weight loss recorded by the weighing sensor 33 per unit time as the output feeding speed, that is, the actual feeding speed of the feeding assembly 30. The preset feeding speed and the actual feeding speed are compared. When the actual feeding speed does not match the preset feeding speed, the controller adjusts the rotation speed of the first driving member 321 so that the actual feeding speed is the same as the preset feeding speed, thereby ensuring the accuracy of the feeding speed.

[0059] In the present application, continuous feeding of the feeding system can be achieved through the coordinated cooperation of the feeding component, the storage component, the feeding component 30 and the controller. In addition, through the cooperation of the controller and the weighing sensor 33, the feeding speed of the feeding bin 31 is accurately matched with the preset feeding speed, which is beneficial to improve the feeding accuracy of the feeding system. In addition, through the cooperation of the controller, the weighing sensor 33 and the first discharge valve 12, the storage tank 11 can replenish the feeding bin 31 in time, which is beneficial to improve the feeding continuity. Therefore, the feeding system of the present application has the advantages of efficient and accurate feeding. And in the same material group, each feed tank 21 feeds all storage tanks 11, the first negative pressure suction component 23 is connected to each storage tank 11, and the controller controls different feeding components 30 to replenish materials in the corresponding speed sequence according to the speed sequence of the feeding speed, which is conducive to further improving the feeding rate, and the coordination of the controller and the feeding speed enables the first negative pressure suction component 23 to quickly and timely regulate multiple feeding routes for replenishment, which is also conducive to improving the energy efficiency of the feeding system, and then helping to reduce production costs. And the coordination of multiple storage tanks 11, multiple feed tanks 21 and multiple feeding components 30 is also conducive to increasing the feeding load per unit time of the feeding system, thereby also facilitating further improving the feeding efficiency.

[0060] In some embodiments, reference Figure 1 and Figure 2The material storage tank 11 includes a first tank portion 111 and a second tank portion 112. The first tank portion 111 is provided with a first discharge valve 12 and a first material level meter 13. The second tank portion 112 is connected to the top of the first tank portion 111. The first pipeline 210 and the second pipeline 230 are both connected to the second tank portion 112. The material storage assembly also includes a second discharge valve 14 and a second material level meter 15. The second discharge valve 14 is provided at the bottom of the second tank portion 112. The second material level meter 15 is provided at one end of the first tank portion 111 close to the second tank portion 112 for detecting the high level of the material. It can be understood that the number of the second discharge valve 14 and the second material level meter 15 are the same as the number of the material storage tank 11. The controller is also used to control the second discharge valve 14 to open to discharge the material according to the closing signal of the first vacuum valve 234. The controller is also used to control the closing of the second discharge valve 14 to end the discharge according to the detection signal of the second material level meter 15, so that there is enough material storage in the material storage tank 11. It can be understood that the controller is electrically connected to the second discharge valve 14 and the second material level meter 15. The second discharge valve 14 separates different tank parts of the storage tank 11 so that the interference between different areas in the tank is small, thereby facilitating the adjustment of the functions of different areas. In addition, the coordination between the controller and the second discharge valve 14, the first vacuum valve 234, and the second material level meter 15 is conducive to improving the continuity of feeding and the control accuracy.

[0061] In some embodiments, the material storage assembly further includes a first dust removal net 16, a first exhaust valve, a first air supply system 17 and a first air supply valve 172. The first dust removal net 16 is arranged at the top of the cavity of the second tank portion 112. For example, the first dust removal net 16 can be an annular net. The first dust removal net 16 can be connected to the second tank portion 112 by snapping or screwing. For example, the first dust removal net 16 can absorb dust by electrostatic adsorption, thereby facilitating the reduction of dust in the granular material, thereby facilitating the improvement of the cleanliness of the material. The first exhaust valve is arranged at the bottom of the second tank portion 112, and the first exhaust valve is arranged on the side of the second unloading valve 14 away from the first tank portion 111. The first air supply system 17 is connected to each second tank portion 112 of the material group through the third pipeline 171, and the access points of the second pipeline 230 and the third pipeline 171 are placed on the side of the first dust removal net 16 away from the first tank portion 111. The first air supply valve 172 is provided on the third pipeline 171. Opening the first air supply valve 172 allows the first air supply system 17 to ventilate the second tank portion 112. For example, the first air supply system 17 can store air or an inert gas. Each storage tank 11 is provided with a first air supply valve 172.

[0062] The controller is also used to control the opening of the first air supply valve 172 and the first exhaust valve to blow and clean dust according to the closing signal of the second unloading valve 14, so as to complete a cycle of feeding and dust cleaning operation. Since the second unloading valve 14 isolates the first tank part 111 and the second tank part 112, and the dust removal operation component acts on the second tank part 112, on the one hand, it is beneficial to reduce the dust removal operation space to improve the dust removal efficiency, thereby shortening the time interval for the next refilling of the storage tank 11, and on the other hand, it is also beneficial to reduce the interference between the unloading process of the first tank part 111 and the cleaning process of the second tank part 112, thereby also helping to reduce the waiting operation time of the storage tank 11. Therefore, the cooperation of the first dust removal net 16, the first exhaust valve, the first air supply system 17, the first air supply valve 172 and the controller is beneficial to further ensure the cleanliness of the material, and at the same time, it is also beneficial to improve the cooperation efficiency of the feeding system to improve the operation efficiency of the feeding system. It can be understood that the controller is electrically connected to the first air supply valve 172 and the first exhaust valve.

[0063] In some embodiments, reference Figure 1 The feeding assembly also includes a feeding bin 24, a second feeding valve 241, a third material level meter 25, a second negative pressure suction assembly 26 and a second vacuum valve 262. The feeding bin 24 is used to put materials. The feeding bin 24 is connected to the top of each feeding tank 21 through a fourth pipeline 240. The second feeding valve 241 is arranged on the fourth pipeline 240. By closing or opening the second feeding valve 241, the feeding process of the feeding bin 24 can be blocked or opened. Each feeding tank 21 is provided with a corresponding second feeding valve 241. The third material level meter 25 is installed at the bottom of the supply tank 21 to detect the low level of the material capacity. The second negative pressure suction component 26 is connected to each supply tank 21 through the fifth pipeline 261. Exemplarily, the second negative pressure suction component 26 can be connected to the top of the supply tank 21. When the second negative pressure suction component 26 is working, it can generate negative pressure in the supply tank 21. The second vacuum valve 262 is arranged on the fifth pipeline 261. The opening or closing of the second vacuum valve 262 can start or stop the vacuum operation process in the supply tank 21. Each supply tank 21 is correspondingly provided with a second vacuum valve 262. The controller is also used to control the opening of the second supply valve 241 and the second vacuum valve 262 to suck the material according to the detection signal of the third material level meter 25, that is, when the material in the supply tank 21 drops to the low level of the material capacity, the second negative pressure suction component 26 is controlled to operate to feed the material from the supply bin to the supply tank 21. The coordination of the above functional parts is conducive to further improving the feeding continuity of the feeding system, thereby further improving the feeding efficiency and the feeding tonnage of the feeding system.

[0064] In some embodiments, the feed tank 21 includes a third tank portion 211 and a fourth tank portion 212, the third tank portion 211 is provided with a third material level meter 25, the fourth tank portion 212 is connected to the top of the third tank portion 211, the fourth pipeline 240 and the fifth pipeline 261 are both connected to the fourth tank portion 212, and the feed assembly also includes a third discharge valve 27 and a fourth material level meter 251. The third discharge valve 27 is provided at the bottom of the fourth tank portion 212, and the fourth material level meter 251 is provided at one end of the third tank portion 211 close to the fourth tank portion 212 for detecting the high level of the material. The controller is also used to control the third discharge valve 27 to open to discharge the material according to the closing signal of the second vacuum valve 262, and the controller is also used to control the closing of the third discharge valve 27 according to the detection signal of the fourth material level meter 251. The third discharge valve 27 is used to separate different tank parts of the supply tank 21, so that the interference between different areas in the tank is small, thereby facilitating the adjustment of the functions of different areas. In addition, the coordination between the controller and the second vacuum valve 262 and the third discharge valve 27 is conducive to improving the continuity of supply and the control accuracy.

[0065] In some embodiments, the feeding assembly further includes a second dust removal net 28, a second exhaust valve, a second air supply system 29 and a second air supply valve 291. The second dust removal net 28 is arranged at the top of the cavity of the fourth tank part 212. For example, the second dust removal net 28 can adsorb dust by electrostatic adsorption. For example, the installation method of the second dust removal net 28 can be the same as the installation method of the first dust removal net 16, so it is not repeated. The second exhaust valve is arranged at the bottom of the fourth tank part 212, and the second exhaust valve is arranged on the side of the third unloading valve 27 away from the third tank part 211.
