It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0026] like Figure 1 and Figure 2 As shown, the material conveying device of this embodiment includes: a silo 10, a conveying member 20, a dust collecting member 30 and a cleaning member 40. The silo 10 has a material storage chamber 11 and a feed port 12 and a dust collecting port 13 connected to the material storage chamber 11. A first filter member 14 is arranged in the silo 10. The first filter member 14 is located between the feed port 12 and the dust collecting port 13. The first filter member 14 is provided with a plurality of filter holes. The discharge end of the conveying member 20 is arranged corresponding to the feed port 12. The dust collecting member 30 is connected to the dust collecting port 13. The cleaning member 40 can separate the dust adsorbed on the first filter member 14 from the first filter member 14.

[0027] Applying the technical solution of this embodiment, the silo 10 has a storage chamber 11, a feed port 12 and a dust suction port 13, the feed port 12 is connected to the storage chamber 11, and the dust suction port 13 is connected to the storage chamber 11. The first filter element 14 is arranged in the silo 10, the first filter element 14 is located between the feed port 12 and the dust suction port 13, and a plurality of filter holes are arranged on the first filter element 14. The discharge end of the conveying member 20 is arranged corresponding to the feed port 12. The dust suction member 30 is connected to the dust suction port 13. The cleaning member 40 can separate the dust adsorbed on the first filter element 14 from the first filter element 14. Through the above-mentioned arrangement, the conveying member 20 can convey the material to the discharge end of the conveying member 20, and then the material can enter the storage chamber 11 through the feed port 12. The dust suction member 30 can remove the dust floating in the storage chamber 11 through the dust suction port 13. When the floating dust is sucked out of the material storage chamber 11 by the dust collecting member 30, some of the dust will be adsorbed on the first filter element 14, which will block the filter holes of the first filter element 14, so that the dust collecting member 30 cannot effectively suck out the floating dust. The cleaning member 40 can separate the dust adsorbed on the first filter element 14 from the first filter element 14, that is, the dust blocking the filter holes is separated from the first filter element 14. The airflow generated by the dust collecting member 30 when working can flow between the external environment, the material storage chamber 11, the first filter element 14 and the dust collecting member 30, so as to achieve dust removal. When the cleaning member 40 separates the dust adsorbed on the first filter element 14 from the first filter element 14, there is no need to stop the operation of the conveying member 20 and the dust collecting member 30, which avoids the situation that the first filter element 14 can be cleaned only after the conveying member 20 and the dust collecting member 30 are stopped, which leads to a decrease in material conveying efficiency. Therefore, the technical solution of this embodiment effectively solves the problem of equipment shutdown required when cleaning the filter structure in the related art.

[0028] It should be noted that when the material bag moves to the discharge end, that is, when the material bag is transported to the conveying silo 10, the operator destroys the material bag and pours the material in the material bag into the silo 10. The material in the material bag is in powder form. After the material enters the silo 10, it will be transported to the next station, which can be a metering buffer warehouse. The conveying member 20 is a conveyor belt. Of course, in other embodiments, the conveying member 20 can also be a plurality of conveying rollers arranged at intervals, or a conveying plate chain.

[0029] like Figures 1 to 3 As shown, the cleaning member 40 includes a first air blowing pipe 41, and the first air blowing pipe 41 has a first air inlet 411 and a first air outlet 412. The first air outlet 412 of the first air blowing pipe 41 extends into the material storage chamber 11 and is arranged toward the first filter element 14. Gas can enter the first air blowing pipe 41 through the first air inlet 411, and then flow out through the first air outlet 412 and blow toward the first filter element 14, so that dust adsorbed on the first filter element 14 can be separated from the first filter element 14 to prevent dust from clogging the filter holes.

[0030] Preferably, the first filter element 14 is a first filter bag, and a plurality of filter holes are provided on the first filter bag. When the dust collecting element 30 is collecting dust, the airflow flows from the outside of the first filter bag to the inside of the first filter bag, and then flows to the dust collecting port. When the first air blowing pipe 41 is blowing air, the airflow flows from the inside of the first filter bag to the outside of the first filter bag, thereby being able to blow away the dust adsorbed on the first filter bag.

[0031] like Figure 3 As shown, the first air outlet 412 of the first air blowing pipe 41 is located between the first filter element 14 and the dust suction port 13. The above arrangement makes the direction of the airflow flowing out through the first air outlet 412 opposite to the direction of the airflow flowing out through the dust suction port 13, that is, when the dust suction port 13 is sucking dust, the dust flows to the dust suction port 13 through the side of the first filter element 14 away from the dust suction port 13, while the airflow flowing out through the first air outlet 412 is blown to the side of the first filter element 14 close to the dust suction port 13, so that the airflow flowing out through the first air outlet 412 can more effectively blow away the dust adsorbed on the first filter element 14, so that the dust no longer blocks the filter hole, and it is convenient for the dust suction element to suck out the dust.

[0032] like Figure 1 and Figure 2 As shown, the cleaning member 40 also includes a control member and a solenoid valve 42 electrically connected to the control member, and the solenoid valve 42 is connected to the first air blowing pipe 41. The control member can control the opening and closing of the solenoid valve 42, and further control whether the gas flows out through the first air blowing pipe 41.

[0033] like Figure 3 As shown, the control component has a pulse controller, which is electrically connected to the electromagnetic valve 42. The first air blowing pipe 41 has a plurality of first air outlets 412 arranged at intervals. The electromagnetic valve 42 includes a plurality of first air outlets 412 arranged at intervals, and the plurality of electromagnetic valves 42 are arranged one by one corresponding to the plurality of first air outlets 412. The control component can control the electromagnetic valve 42 to open once at a preset interval through the pulse controller, that is, the first air blowing pipe 41 blows air to the first filter element 14 once at a preset interval, so that the dust adsorbed on the first filter element 14 can be separated from the first filter element 14. The plurality of first air outlets 412 can make more gas flow out through the first air blowing pipe 41 at the same time, thereby improving the removal effect of the dust adsorbed on the first filter element 14.

[0034] It should be noted that the preset interval time refers to the interval time for the solenoid valve to open once, which can be 5s, 10s, 20s, or other values.

[0035] like Figure 1As shown, the silo 10 includes a silo body 15 and a silo door 16, the feed port 12 is arranged on the silo body 15, and the silo door 16 is rotatably arranged at the feed port 12. The silo body 15 and the silo door 16 can shield the materials in the silo to prevent the materials from being contaminated. The silo door 16 is rotatably arranged at the feed port 12, so that when the silo door 16 is opened, materials can be added to the storage cavity 11, and when the silo door 16 is closed, the storage cavity 11 can be isolated from the external environment, and then the silo door 16 can protect the materials in the silo 10.

[0036] Preferably, the silo body 15 includes a delivery section and a guide section. The delivery section is arranged above the guide section. The silo door 16 is arranged on the delivery section. The shape of the guide section is a quadrangular pyramid. The tip of the quadrangular pyramid is provided with a connecting port. After the material enters the delivery section, it flows out from the connecting port. The bottom of the quadrangular pyramid is located between the delivery section and the tip of the quadrangular pyramid. A temporary storage plate is also provided on the outside of the delivery section. The feed port 12 is located above the temporary storage plate. The length direction of the temporary storage plate is arranged parallel to the extension direction of the conveying member 20. When delivering materials, the material bags can be temporarily stored on the temporary storage board, which is convenient for the operator to open the material bags and put the materials into the silo 10. The extension direction of the conveying member 20 is Figure 1 From the lower left corner to Figure 1 direction of the upper right corner.

[0037] like Figure 1 and Figure 3 As shown, the silo 10 further includes a driving member 17 connected between the silo body 15 and the silo door 16, and the driving member 17 can drive the silo door 16 to open and close relative to the feed port 12. The driving member 17 makes it easier to open the silo door 16, and after the silo door 16 is opened, it can be kept in the open position to prevent the silo door 16 from closing, so as to facilitate the addition of materials.

[0038] It should be noted that the driving member 17 includes two. The two sides of the warehouse body in the extension direction of the conveying member are respectively the first side and the second side, and the first side is located between the conveying member and the second side. One driving member is arranged on the first side, and the other driving member is arranged on the second side. Two support rods are also arranged on the warehouse body 15, one of the two support rods is the first support rod, and the other is the second support rod. In the length direction of the warehouse door 16, the first support rod, the first side, the second side and the second support rod are arranged in sequence, and the length direction of the warehouse door 16 is the same as the extension direction of the conveying member 20. The first support rod and the second support rod each support a driving member 17, the first end of the driving member 17 is hingedly connected to the support rod, and the second end of the driving member 17 is hingedly connected to the warehouse door 16. The warehouse door 16 is driven to open by the driving member 17, and then the warehouse door 16 is fixed. Compared with manually opening the warehouse door 16 and then fixing the warehouse door 16 with a padlock, the safety risk is reduced. The warehouse door 16 has an open position and a closed position. When the door 16 is in the open position, the door 16 is separated from the feed port 12, and when the door 16 is in the closed position, the door 16 covers the feed port 12. The driving member 17 is a cylinder. Of course, in an embodiment not shown in the figure, the driving member 17 can also be a hydraulic cylinder, or the driving member 17 is a driving motor. The door 16 is provided with a gear, and the driving motor drives the gear to rotate, thereby driving the door to open. The first end of the cylinder is hingedly connected to the support rod, and the telescopic rod of the cylinder is hingedly connected to the door 16.

[0039] like Figure 3 As shown, the material conveying device further includes a first detection member capable of detecting the position of the bin door 16, and the first detection member is electrically connected to the control member so that the control member controls the operation of the solenoid valve 42. The first detection member can detect the position of the bin door 16, and then when the bin door 16 is opened, the first detection member can transmit a detection signal to the control member, so that the control member can control the operation of the solenoid valve 42, that is, the gas is blown out through the first gas outlet 412.

[0040] like Figure 1 As shown, a second filter 50 is provided between the dust suction port 13 and the dust suction member 30, and the cleaning member 40 further includes a second air blowing pipe 43, the second air blowing pipe 43 has a second air inlet 431 and a second air outlet 432, and the second air outlet 432 extends into the second filter 50. The second filter 50 can filter the dust flowing out through the dust suction port 13 again. The gas can flow in through the second air inlet 431 and then flow out through the second air outlet 432, and the second air outlet 432 can remove the dust adsorbed on the second filter 50, thereby preventing the dust from clogging the second filter 50.

[0041] It should be noted that the second filter element 50 includes a shell and a second filter bag disposed in the shell. When the dust collecting element 30 is sucking dust, the gas flows from the outside of the second filter bag to the inside of the second filter bag. When the second air blowing pipe 43 is blowing air, the gas flows from the inside of the second filter bag to the outside of the second filter bag. The dust collecting element 30 includes a dust removal fan, a first connecting pipe, and a second connecting pipe. The first connecting pipe is connected between the dust suction port 13 and the shell, and the second connecting pipe is connected between the shell and the dust removal fan.

[0042] Specifically, a plurality of solenoid valves are also arranged at intervals on the second air blowing pipe 43, and the second air blowing pipe 43 has a plurality of second air outlets 432 arranged at intervals, and the plurality of solenoid valves 42 arranged on the second air blowing pipe 43 are arranged one-to-one correspondingly to the plurality of second air outlets 432. The pulse controller can control the solenoid valve to open once at a preset interval, that is, the second air blowing pipe 43 blows air to the second filter element 50 once at a preset interval, so that the dust adsorbed on the second filter element 50 is separated from the second filter element 50. The plurality of second air outlets 432 can make more gas flow out through the second air blowing pipe 43 at the same time, thereby improving the removal effect of the dust adsorbed on the second filter element 50.

[0043] Preferably, the control member also has a controller, and the material conveying device also includes a second detection member arranged at the discharge end of the conveying member 20, the second detection member is electrically connected to the controller, and the second detection member is used to detect whether there is a material bag at the discharge end of the conveying member 20, so that the controller controls whether the conveying member 20 is running, that is, when there is no material bag at the discharge end of the conveying member, the conveying member runs to convey the material bag to the discharge end. The material conveying device also includes an air source, which is connected to the first air inlet 411 and the second air inlet 431.

[0044] like Figures 1 to 4 As shown, the material transfer production line of this embodiment includes a material conveying device, and the material conveying device is the above-mentioned material conveying device. When the above-mentioned material conveying device is in use, the cleaning member 40 can remove the dust adsorbed on the first filter element 14, avoiding the need to shut down the dust collecting member 30 and the conveying member 20 when the first filter element 14 needs to be cleaned, thereby improving production efficiency. The material transfer production line with the above-mentioned material conveying device also has the above-mentioned advantages.

[0045] Preferably, the material transfer production line also includes a robotic arm and a third detection component. The conveying member is arranged between the silo and the robotic arm. The end of the conveying member 20 close to the robotic arm is the feeding end. The third detection component is arranged at the feeding end of the conveying member 20. The third detection component is used to detect whether there is a material bag at the feeding end and transmit a detection signal to the controller to control whether the robotic arm transports the material bag. That is, when there is no material bag at the feeding end, the controller controls the robotic arm to transport the material bag to the conveying member 20.

[0046] It should be noted that when the third detection member detects that there is a material bag at the end of the conveying member 20 close to the robot arm and the second detection member detects that there is no material bag at the discharge end, the conveying member 20 conveys the material bag to the discharge end. The first detection member, the second detection member and the third detection member are all photoelectric sensors.

[0047] In this embodiment, the working process of the material transfer production line is as follows: after the material bag is placed on the conveying member 20, the third detection member is triggered, and the conveying member 20 starts to deliver the material to the bin door 16. When the material is ready to be fed, the control switch of the bin door 16 is pressed. The controller receives the signal and controls the driving member 17 to open the bin door. The first detection member detects that the bin door is open and outputs a signal to the controller. The controller controls the dust collecting member 30 to start, and controls the cleaning member 40 to start, and at the same time gives a start signal to the pulse controller. The pulse controller controls the first blowing pipe 41 and the second blowing pipe 43 to blow air in sequence according to the preset interval time pulse, respectively realizing the blowing of the first filter 14 and the second filter 50, thereby removing the adsorbed dust. At this point, through the control member, the cleaning member 40, the first detection member, the second detection member and the third detection member, the places that originally needed to be completed manually one by one and could not be cleaned in time can be automatically controlled, thereby improving production efficiency.
