Description

Technical Field

[0001] This application relates to the field of material handling technology, and in particular to a material handling device. Background Technology

[0002] The core of a secondary battery typically includes a positive electrode, a negative electrode, a separator, positive electrode tabs, negative electrode tabs, and an insulating sheet. The positive electrode generally uses aluminum foil as a substrate, with positive electrode material uniformly coated on both sides. The negative electrode generally uses copper foil as a substrate, with negative electrode material uniformly coated on both sides. Therefore, in the manufacturing process of secondary batteries, foil materials (such as aluminum foil, copper foil, etc.) need to be transported to mass-produce positive and negative electrodes. In existing technologies, conveyor belts on material handling devices are commonly used to transport foil materials. During transportation and processing, the foil materials are easily adhered to the conveyor belt due to static electricity, stickiness, water absorption, etc., making it extremely difficult to separate the foil materials from the conveyor belt at the end of the transport process, thus affecting the rapid use of the foil materials. Summary of the Invention

[0006] The air blowing component includes a plurality of air blowing tubes, which are arranged at intervals along the length of the air blowing component. Each air blowing tube has an air blowing port, and the air blowing port of each air blowing tube is used to blow out gas.

[0007] Both the connecting roller and the conveying roller are rotatably connected to the bracket.

[0010] The air blowing component includes an air distribution section, which has an air distribution chamber. The air distribution section is provided with a plurality of air delivery holes and air vents. The plurality of air delivery holes are disposed on the chamber wall of the air distribution section and are arranged at intervals along the length direction of the air blowing component. Each air delivery hole penetrates the chamber wall of the air distribution section. The air vents are disposed on the chamber wall of the air distribution section and are spaced apart from the plurality of air delivery holes. The air vents penetrate the chamber wall of the air distribution section.

[0011] The vent is used to introduce gas into the gas distribution section, and the air outlet of each air blowing pipe is opposite to and connected to one of the air outlets.

[0012] In one possible implementation, the air blowing device further includes a vent pipe having a connection port and a vent, the connection port and the vent being located at opposite ends of the vent pipe, respectively.

[0013] The connection port is opposite to and connected to the vent hole, and the vent hole is used to introduce gas into the vent pipe.

[0014] In one possible implementation, the air blowing component further includes two rotating shafts, which are respectively connected to opposite ends of the air distribution section along its length, and the two rotating shafts are coaxially arranged.

[0015] The material conveying device also includes a controller, and both of the rotating shafts are signal-connected to the controller. The controller can control the rotation of the two rotating shafts so that the gas distribution section rotates around the axes of the two rotating shafts.

[0016] In one possible implementation, each of the air tubes is a deformable hose.

[0017] In one possible implementation, each of the air-blowing tubes includes a first tube and a second tube, the first tube and the second tube being detachably connected and communicating with each other, the air inlet being located at the end of the first tube opposite to the second tube, and the air-blowing port being located at the end of the second tube opposite to the first tube.

[0018] In one possible implementation, the second pipe includes a plurality of connecting pipes, which are detachably connected in sequence, and adjacent connecting pipes are in communication.

[0019] The outermost of the plurality of connecting tubes is detachably connected to and communicates with the first tube, and the air inlet is located at the end of the outermost of the plurality of connecting tubes opposite to the first tube.

[0020] In one possible implementation, the material conveying device further includes a support frame, and the conveying roller further includes a first conveying shaft and a second conveying shaft, the first conveying shaft and the second conveying shaft being connected to opposite ends of the drive roller shaft, and the first conveying shaft and the second conveying shaft being coaxially arranged;

[0021] The transmission roller shaft is rotatably connected to the bracket via the first transmission shaft and the second transmission shaft.

[0024] In one possible implementation, the material conveying device further includes a plurality of auxiliary rollers, each of which has a peripheral side surface. Along the conveying direction of the material conveying device, the plurality of auxiliary rollers are located between the connecting roller and the conveying roller, and the plurality of auxiliary rollers are arranged at intervals. The axes of the plurality of auxiliary rollers are parallel to the axis of the conveying roller.

[0025] The connecting surface is rotatably connected to the peripheral surfaces of the plurality of auxiliary rollers.

[0026] The beneficial effects of this invention are as follows: Material is placed on the bearing surface of the conveyor belt. Driven by the connecting roller and the conveyor roller, the conveyor belt can move the material towards the conveyor roller. Since the conveyor roller is equipped with air-blowing components on its side, the air outlets of multiple air-blowing pipes of the components all face the portion of the conveyor belt that is fitted onto the conveyor roller, and all air outlets face the connecting surface of the conveyor belt. The conveyor belt has multiple ventilation holes; therefore, the airflow blown from the air outlets of the multiple air-blowing pipes can pass through several ventilation holes in the conveyor belt and reach the back of the material. This reduces the adhesion between the material and the conveyor belt after the back of the material is subjected to force, thus facilitating quick access for the operator when the material reaches the conveyor roller. Especially when the material is foil, the airflow blown from the air outlets of the multiple air-blowing pipes reaches the back of the foil, reducing the adhesion between the foil and the conveyor belt due to static electricity, stickiness, etc., after the back of the foil is subjected to force, thus facilitating quick access for the operator when the foil reaches the conveyor roller.

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0037] Please see Figure 1 , Figure 1 This is a partial structural diagram of a material conveying device in the related art. In the related art, the material conveying device 200 includes a conveyor belt 210, a conveyor roller 220, and a connecting roller 230. The conveyor roller 220 is located at the end point of the material conveying device 200, and the connecting roller 230 is located at the beginning point of the material conveying device 200. The conveyor belt 210 is fitted onto the connecting roller 230 and the conveyor roller 220. The connecting roller 230 and the conveyor roller 220 rotate in the same direction, driving the conveyor belt 210 to rotate. The conveyor belt 210 is used to carry materials. Rotation of the conveyor belt 210 allows materials placed on the conveyor belt 210 to move from the connecting roller 230 to the conveyor roller 220.

[0038] To facilitate the separation of material from the conveyor belt 210 at the end of the material conveying device 200, especially when the material is foil, the conveyor roller 220 at the end is typically hollow and perforated, forming multiple uniform through holes (not shown). Simultaneously, the conveyor belt 210 is a mesh belt with multiple flow holes 211. When the conveyor belt 210 rotates around the conveyor roller 220 and the connecting roller 230, compressed air is introduced through the end of the conveyor roller 220. This compressed air passes through the multiple through holes of the conveyor roller 220 and the multiple flow holes 211 of the conveyor belt 210 to reach the back of the foil on the conveyor belt 210, thereby separating the foil from the conveyor belt 210. However, in related technologies, since the surface of the transfer roller 220 has uniform openings, a large portion of the compressed gas introduced into the transfer roller 220 will escape to the outside of the material transfer device 200 through the through holes of the transfer roller 220 that are not covered by the transfer belt 210. Therefore, in related technologies, the separation effect between the foil and the transfer belt 210 is not good.

[0039] Please refer to the following: Figure 2 and Figure 3 , Figure 2 A simplified structural diagram of the material conveying device provided in the embodiments of this application; Figure 3 for Figure 2A partial structural schematic diagram of the material conveying device is shown. For ease of description, in this application, the height direction of the material conveying device 100 is defined as the Z-axis direction.

[0040] This application provides a material conveying device 100, including a support 150, a conveyor belt 110, a conveyor roller 120, a connecting roller 130, and an air blowing element 140. Both the connecting roller 130 and the conveyor roller 120 are mounted on the support 150. Along the conveying direction of the material conveying device 100, the connecting roller 130 and the conveyor roller 120 are spaced apart and opposite each other. The conveyor belt 110 is sleeved on the connecting roller 130 and the conveyor roller 120. The air blowing element 140 is located on the side of the conveyor roller 120.

[0041] It should be noted that, Figure 2 The purpose is merely to illustrate the connection relationship between the support 150, conveyor belt 110, conveyor roller 120, and connecting roller 130, and is not to specifically limit the connection position or specific structure of each component, nor to specifically limit the number or type of components of the material conveying device 100.

The bearing surface 111 and the connecting surface 112 are arranged facing away from each other along the thickness direction of the conveyor belt 110. It can be understood that both the bearing surface 111 and the connecting surface 112 are annular surfaces. The bearing surface 111 is used to bear materials; the connecting surface 112 is used to connect with the connecting roller 130 and the conveyor roller 120, so that the conveyor belt 110 is fitted onto the connecting roller 130 and the conveyor roller 120. The conveyor belt 110 is provided with multiple air vents 113. Along the thickness direction of the conveyor belt 110, the multiple air vents 113 penetrate the bearing surface 111 and the connecting surface 112.

The second connecting shaft is set at an angle to the second driving surface. The first connecting shaft 132, the second connecting shaft, and the connecting roller shaft 131 are coaxially arranged. The first connecting shaft 132 and the second connecting shaft are used to rotatably connect the connecting roller 130 to the bracket 150.

[0046] Please see Figure 4 , Figure 4 for Figure 3 The diagram shows the structure of the transfer roller of the material transfer device. The transfer roller 120 includes a transfer roller shaft 121, a first transfer shaft 122, and a second transfer shaft 123. The first transfer shaft 122 and the second transfer shaft 123 are respectively connected to opposite ends of the transfer roller shaft 121.

[0047] The transfer roller shaft 121 is cylindrical. The transfer roller shaft 121 includes a first transfer surface 1211, a second transfer surface 1212, and a peripheral surface 1213. The first transfer surface 1211 and the second transfer surface 1212 are arranged opposite to each other along the length of the transfer roller shaft 121. The peripheral surface 1213 connects the first transfer surface 1211 and the second transfer surface 1212.

[0048] The transfer roller shaft 121 is provided with a plurality of air blowing guide grooves 124. Each air blowing guide groove 124 is an annular groove. Each air blowing guide groove 124 is recessed into the circumferential side surface 1213 of the transfer roller shaft 121 and extends along the circumferential direction of the transfer roller shaft 121. Each air blowing guide groove 124 surrounds the axis of the transfer roller shaft 121. Each air blowing guide groove 124 is coaxially arranged with the transfer roller shaft 121. The plurality of air blowing guide grooves 124 are spaced apart along the length direction of the transfer roller shaft 121.

[0049] A first transmission shaft 122 protrudes from the first transmission surface 1211 of the transmission roller shaft 121 and extends in a direction away from the first transmission surface 1211. The first transmission shaft 122 is set at an angle to the first transmission surface 1211. A second transmission shaft 123 protrudes from the second transmission surface 1212 of the transmission roller shaft 121 and extends in a direction away from the second transmission surface 1212. The second transmission shaft 123 is set at an angle to the second transmission surface 1212. The first transmission shaft 122, the second transmission shaft 123, and the transmission roller shaft 121 are coaxially arranged. The first transmission shaft 122 and the second transmission shaft 123 are used to rotatably connect the transmission roller 120 to the support 150.

[0050] Please see Figure 5 , Figure 5 for Figure 3The diagram shows the structure of the air blowing component of the material conveying device. The air blowing component 140 includes an air distribution section 141, an air inlet pipe 142, and multiple air blowing pipes 143. The air inlet pipe 142 and the multiple air blowing pipes 143 are all connected to the air distribution section 141.

[0051] The gas distribution section 141 includes two end walls 1411 and a peripheral side wall 1413. The two end walls 1411 are disposed opposite each other along the length direction of the gas distribution section 141. The peripheral side wall 1413 is connected between the two end walls 1411. The two end walls 1411 and the peripheral side wall 1413 form a gas distribution cavity. It can be understood that the gas distribution section 141 has a gas distribution cavity, and the two end walls 1411 and the peripheral side wall 1413 form the cavity wall of the gas distribution cavity. In this embodiment, the cross-section of the gas distribution section 141 is rectangular. That is, the peripheral side wall 1413 is formed by connecting four rectangular side walls. In other embodiments, the cross-section of the gas distribution section 141 may also be circular.

[0052] The gas distribution section 141 is provided with a vent 1414 and a plurality of gas delivery holes 1415. The vent 1414 is located on the wall of the gas distribution chamber and penetrates the wall. The plurality of gas delivery holes 1415 are located on the wall of the gas distribution chamber and penetrate the wall. The plurality of gas delivery holes 1415 are arranged at intervals along the length of the gas distribution section 141. The vent 1414 and the plurality of gas delivery holes 1415 are spaced apart. In this embodiment, the vent 1414 is located on one of the end walls 1411 and penetrates two surfaces of the end wall 1411 that are opposite to each other in the thickness direction. The plurality of gas delivery holes 1415 are located on the peripheral sidewall 1413 and are arranged at intervals along the length of the gas distribution section 141. Each gas delivery hole 1415 penetrates two surfaces of the peripheral sidewall 1413 that are opposite to each other in the thickness direction.

[0053] The vent pipe 142 is a hollow tube open at both ends. The vent pipe 142 has a vent 1421 and a connection port. The vent 1421 and the connection port are located at opposite ends of the vent pipe 142. The vent 1421 of the vent pipe 142 is used to introduce gas into the vent pipe 142. The connection port of the vent pipe 142 is opposite to and communicates with the vent hole 1414 of the gas distribution section 141.

[0054] Each air tube 143 is a hollow tube open at both ends. Each air tube 143 has an air inlet 1431 and an air outlet. The air inlet 1431 and the air outlet are located at opposite ends of the air tube 143. In this embodiment, each air tube 143 is a deformable flexible tube. Exemplarily, each air tube 143 is a plastic flexible tube, or each air tube 143 is a metal flexible tube. In other embodiments, each air tube 143 may also be non-deformable.

[0055] The number of air-blowing pipes 143 is the same as the number of air outlets 1415 in the air distribution section 141. Multiple air-blowing pipes 143 are connected to the peripheral sidewall 1413 of the air distribution section 141, and are spaced apart along the length of the air-blowing member 140. The air outlet of each air-blowing pipe 143 is opposite to and communicates with one air outlet 1415 of the air distribution section 141. The air-blowing port 1431 of each air-blowing pipe 143 is used for blowing air.

[0056] In one possible implementation, the air blowing pipe 143 includes a first pipe and a second pipe. Both the first pipe and the second pipe are hollow tubes open at both ends. The first pipe and the second pipe are detachably connected and communicate with each other. Exemplarily, the first pipe and the second pipe are connected by threads, or by snap-fit ​​connections. The air inlet of the air blowing pipe 143 is located at the end of the first pipe opposite to the second pipe. The air blowing port 1431 of the air blowing pipe 143 is located at the end of the second pipe opposite to the first pipe.

[0057] In another possible implementation, the air blowing pipe 143 includes a first pipe and a second pipe. The second pipe is formed by splicing multiple connecting pipes. The first pipe is a hollow tube open at both ends. The multiple connecting pipes are also hollow tubes open at both ends. The multiple connecting pipes are detachably connected in sequence to form the second pipe. Adjacent connecting pipes are connected. The outermost connecting pipe is detachably connected to and communicates with the first pipe. The air inlet of the air blowing pipe 143 is located at the end of the first pipe facing away from the second pipe. The air blowing port 1431 of the air blowing pipe 143 is located at the end of the connecting pipe farthest from the first pipe facing away from the first pipe. Exemplarily, adjacent connecting pipes can be connected by threads or by snap-fit ​​connections.

[0058] In another possible implementation, the air blowing element 140 further includes two rotating shafts. The two rotating shafts are respectively connected to the two end walls 1411 of the air distribution section 141, and are coaxially arranged. The material conveying device 100 also includes a controller, and both rotating shafts are signal-connected to the controller. The controller can control the two rotating shafts to rotate around their axes, causing the air distribution section 141 to rotate around the axes of the two rotating shafts, thereby causing the plurality of air blowing pipes 143 connected to the air distribution section 141 to rotate around the axes of the two rotating shafts. In this embodiment, the material conveying device 100 also includes a venting element (not shown), which is used to supply gas to the air blowing element 140. In other embodiments, the venting element may also exist independently of the material conveying device 100.

[0059] Please refer to the following: Figure 1 and Figure 6 , Figure 6 for Figure 3A cross-sectional schematic diagram of the material conveying device along the AA direction. The connecting roller 130 is located at the starting point of the material conveying device 100, and the conveying roller 120 is located at the ending point of the material conveying device 100. The axes of the connecting roller 130 and the conveying roller 120 are parallel to each other (with certain process tolerances allowed). The connecting roller 130 and the conveying roller 120 rotate in the same direction, and their linear velocities are the same. In this embodiment, along the height direction (Z-axis direction) of the material conveying device 100, the connecting roller 130 and the conveying roller 120 can be at the same height.

[0060] In other embodiments, the connecting roller 130 and the conveying roller 120 may be at different heights along the height direction (Z-axis direction) of the material conveying device 100.

[0061] A conveyor belt 110 is fitted onto a connecting roller 130 and a conveyor roller 120. The connecting surface 112 of the conveyor belt 110 is rotatably connected to the peripheral side surfaces 1313 of the connecting roller 130 and 1213 of the conveyor roller 120. The rotation of the connecting roller 130 and the conveyor roller 120 provides friction to the connecting surface 112 of the conveyor belt 110, causing the conveyor belt 110 to rotate along with the connecting roller 130 and the conveyor roller 120. The bearing surface 111 of the conveyor belt 110 carries material. The rotation of the conveyor belt 110 around the connecting roller 130 and the conveyor roller 120 allows the material to move towards the conveyor roller 120.

[0062] In one possible implementation, the material conveying device 100 further includes a plurality of auxiliary rollers. Each auxiliary roller has a circumferential side surface. The plurality of auxiliary rollers are located between the connecting roller 130 and the conveying roller 120, and are parallel to the connecting roller 130 and the conveying roller 120. The connecting surface 112 of the conveyor belt 110 is rotatably connected to the circumferential side surfaces of the plurality of auxiliary rollers. The plurality of auxiliary rollers are used to support the conveyor belt 110 during rotation, thereby improving the rotational stability of the conveyor belt 110.

[0063] Please refer to the following: Figure 1 , Figure 6 , Figure 7 and Figure 8 , Figure 7 for Figure 4 A schematic diagram of the assembly structure of the transfer roller and the air blowing component at the first angle; Figure 8 for Figure 4This is a schematic diagram of the assembly structure of the transfer roller and the air blowing element at a second angle. Along the conveying direction of the material conveying device 100, the air distribution section 141 of the air blowing element 140 is located on the side of the transfer roller 120 near the connecting roller 130. The air pipe 142 of the air blowing element 140 is used to introduce gas into the air distribution section 141. Each air blowing pipe 143 of the air blowing element 140 extends into an air blowing guide groove 124 of the transfer roller 120, and is spaced apart from the groove wall of the air blowing guide groove 124. The air blowing port 1431 of each air blowing pipe 143 faces the portion of the conveyor belt 110 that is fitted onto the transfer roller 120. The air blowing port 1431 of each air blowing pipe 143 faces the connecting surface 112 of the conveyor belt 110. It can be understood that when the connecting roller 130 and the transfer roller 120 rotate, causing the conveyor belt 110 to rotate, a portion of the conveyor belt 110 is always fitted onto the transfer roller 120. The air outlet 1431 of each air blowing pipe 143 remains relatively stationary with respect to the axis of the conveyor roller 120. The air outlet 1431 of each air blowing pipe 143 always faces the portion of the conveyor belt 110 that is fitted onto the conveyor roller 120. Compressed gas is introduced into the air distribution section 141 through the air pipe 142. The compressed gas in the air distribution section 141 enters the multiple air blowing pipes 143 and is blown through the air outlets 1431 of the multiple air blowing pipes 143 onto the portion of the conveyor belt 110 that is fitted onto the conveyor roller 120.

[0064] It should be noted that the air blowing component 140 can be directly connected to the bracket 150 or connected to the transmission roller 120, which is equivalent to the air blowing component 140 being indirectly connected to the bracket 150 through the transmission roller 120. This application embodiment does not specifically limit this.

[0065] Understandably, when material is placed on the bearing surface 111 of the conveyor belt 110, the conveyor belt 110 can move the material from the connecting roller 130 to the conveyor roller 120 under the drive of the connecting roller 130 and the conveyor roller 120. Since the conveyor roller 120 is provided with an air blowing element 140 on its side, the air blowing ports 1431 of the multiple air blowing pipes 143 of the air blowing element 140 all face the part of the conveyor belt 110 that is sleeved on the conveyor roller 120, and the air blowing ports 1431 of the multiple air blowing pipes 143 face the connecting surface 112 of the conveyor belt 110. The conveyor belt 110 is provided with multiple air vents 113. Therefore, the airflow blown out from the air vents 1431 of the multiple air blowing pipes 143 can pass through the air vents 113 of the conveyor belt 110 and blow onto the back of the material. After the back of the material is subjected to force, the adsorption force between the material and the conveyor belt 110 is reduced. As a result, when the material reaches the conveyor roller 120, that is, when the material reaches the end of the material conveying device 100, it is convenient for the operator to quickly pick up the foil.

[0066] Especially when the material is foil, the airflow blown out from the air outlets 1431 of the multiple air blowing pipes 143 can pass through several air vents 113 of the conveyor belt 110 and blow onto the back of the foil. After the back of the foil is subjected to force, the adsorption force between the foil and the conveyor belt 110 due to static electricity, stickiness and other reasons is reduced, so that after the foil reaches the end of the material conveying device 100, it is convenient for the operator to quickly pick up the foil.

[0067] Compared to related technologies where gas is uniformly blown from the surface of the conveyor roller 220 to separate the material on the conveyor belt 210, this application uses an air-blowing component 140 located on the side of the conveyor roller 120. The airflow from the air outlet 1431 of the air-blowing component 140 is always directed towards the portion of the conveyor belt 110 that is fitted onto the conveyor roller 120. This allows the material carried on the portion of the conveyor belt 110 fitted onto the conveyor roller 120 to be separated from the conveyor belt 110. Therefore, it saves gas flow and improves blowing accuracy, ensuring effective separation of the material from the conveyor belt 110. It not only avoids poor blowing effect but also eliminates the need to increase gas pressure or flow rate, thus preventing gas waste and excessive blowing noise.

[0068] In this application, the air blowing component 140 is always stationary. To improve gas utilization, a sealing solution between the air vent and the air vent pipe 142 of the air blowing component 140 can be easily achieved. However, in related technologies, since compressed gas needs to be introduced into the end of the transfer roller 220 during its rotation, it is difficult to achieve a sealing solution at the end of the transfer roller 120.

[0069] Furthermore, the multiple air-blowing pipes 143 of the air-blowing component 140 are all deformable flexible hoses, thus allowing adjustment of the blowing angle of the multiple air-blowing pipes 143 according to usage requirements to meet the air output needs of the material conveying device 100 in various directions. Each air-blowing pipe 143 of the air-blowing component 140 is spaced apart from the wall of the air-blowing guide groove 124 it is located in. Therefore, during the rotation of the conveying roller 120, each air-blowing pipe 143 of the air-blowing component 140 will not interfere with the rotation of the conveying roller 120, avoiding the air-blowing component 140 affecting the normal rotation of the conveying roller 120, and also avoiding mutual interference between the conveying roller 120 and the air-blowing pipe 143, which could easily damage the conveying roller 120 or the air-blowing pipe 143.

[0070] The blowing pipe 143 of the blowing component 140 is formed by a detachable connection of a first pipe and a second pipe, and the second pipe is formed by a detachable connection of multiple connecting pipes. Therefore, the length of the blowing pipe 143 of the blowing component 140 can be adjusted according to actual needs so that the airflow blown out of the blowing port 1431 of the blowing pipe 143 can flow precisely to the back of the material, so that the material separates from the conveyor belt 110 when it reaches the end of the material conveying device 100. For example, when the diameter of the conveyor roller 120 is large, the length of the air blowing pipe 143 can be extended by increasing the number of connecting pipes, so that after the air blowing pipe 143 is arranged along the air blowing guide groove 124 of the conveyor roller 120, the air blowing port 1431 of the air blowing pipe 143 can be directly facing the part of the conveyor belt 110 that is sleeved on the conveyor roller 120; conversely, when the diameter of the conveyor roller 120 is small, the length of the air blowing pipe 143 can be shortened by reducing the number of connecting pipes, so that the air blowing port 1431 of the air blowing pipe 143 can be directly facing the part of the conveyor belt 110 that is sleeved on the conveyor roller 120.

[0071] Gas is introduced into the air distribution section 141 through the vent pipe 142 to improve the sealing performance of the air blowing component 140. The air distribution section 141 of the air blowing component 140 connects multiple air blowing pipes 143. By introducing gas into the air distribution section 141, airflow can be blown out from the air blowing ports 1431 of the multiple air blowing pipes 143, simplifying the air path structure and eliminating the need for individual air supply to each air blowing pipe 143.

[0072] By controlling the air distribution section 141 of the air blowing component 140 to rotate around the axes of the two rotating shafts of the air blowing component 140, the multiple air blowing pipes 143 connected to the air distribution section 141 can rotate around the axes of the two rotating shafts. Therefore, the angle between the multiple air blowing pipes 143 and the conveyor belt 110 can be adjusted according to the usage requirements, thereby adjusting the position of the air blowing port 1431 of the multiple air blowing pipes 143 facing the conveyor belt 110.

[0073] The embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
