The feeding device comprises a feeding mechanism and a discharging mechanism arranged at intervals along the up-down direction. The feeding mechanism has a feeding surface conveying along the horizontal direction. The discharging mechanism has a discharging surface conveying along the horizontal direction. The transfer device has a transfer part movable between the feeding surface and the discharging surface. The material passing device comprises a first material passing mechanism and a second material passing mechanism located on both sides of the transfer part. The first material passing mechanism has a first conveyor conveying towards the transfer part or away from the transfer part, and a first push rod movable between the transfer part and the first conveyor. The second material passing mechanism has a second conveyor conveying towards the transfer part or away from the transfer part, and a second push rod movable between the transfer part and the second conveyor.

[0006] The technical scheme has at least the following beneficial effects: when conveying the material, the feeding, discharging and transferring of the material can be realized according to the use requirement; when the material needs to be fed, the bin loaded with the material is placed on the feeding surface of the feeding mechanism, the feeding surface conveys the bin to the transferring part, the transferring part tightly fixes the bin, at this time, the material can be transferred from the first transferring mechanism or the second transferring mechanism to the required work station, for example, when the material needs to be fed to the first transferring mechanism, the second push rod in the second transferring mechanism moves to the bin, pushes the material in the bin out to the first conveyor of the first transferring mechanism, the first conveyor sends the material to the next work station, or when the material needs to be fed to the second transferring mechanism, the first push rod in the first transferring mechanism moves to the bin, pushes the material in the bin out to the second conveyor of the second transferring mechanism, the second conveyor sends the material to the next work station, when the feeding of the material in the bin is completed, the transferring part conveys the bin to the discharging surface of the discharging mechanism, the discharging surface sends the bin after the feeding is completed; when the material needs to be discharged, the empty bin is placed on the discharging surface of the discharging mechanism, the discharging surface conveys the bin to the transferring part, the transferring part tightly fixes the bin, at this time, the material can be sent into the bin from the first discharging surface or the second discharging surface, and after the material is moved out of the first discharging surface and the second discharging surface, the first push rod and the second push rod further push the material into the bin, so that the material is in place in the bin, then the transferring part conveys the bin to the feeding surface of the feeding mechanism, the feeding surface sends the bin loaded with the material; when the material needs to be transferred, the bin is fixed in the transferring part, at this time, the external material can be sent into the first conveyor, then into the bin, then transferred from the bin to the second conveyor, and then sent out from the second conveyor to the external work station, or the external material can be sent into the second conveyor, then into the bin, then transferred from the bin to the first conveyor, and then sent out from the first conveyor to the external work station. Thus, the feeding, discharging and transferring of the material can be realized according to the use requirement, the overall versatility is high, and the production efficiency is improved.

[0007] As a further improvement of the above technical solution, the feeding mechanism comprises a feeding bottom plate, a first conveying part and a second conveying part arranged on the feeding bottom plate, and a material supporting part located between the first conveying part and the second conveying part. The first conveying part is provided with a first conveying belt capable of rotating movement, the second conveying part is provided with a second conveying belt capable of rotating movement, the top side of the first conveying belt and the top side of the second conveying belt form the feeding surface, and the material supporting part is provided with a supporting plate capable of moving up and down. When it is needed to feed the hopper to the transfer gripper, the hopper is placed on the top side of the first conveying belt in the first conveying part and the second conveying belt in the second conveying part. When the first conveying belt and the second conveying belt rotate, the hopper can be driven to move towards the transfer gripper. When the hopper moves above the supporting plate, the supporting plate moves up to protrude out of the feeding surface, and the hopper is supported away from the feeding surface. At this time, the transfer part can clamp and fix the hopper. When the transfer gripper needs to feed the hopper to the feeding surface, the transfer gripper places the hopper on the supporting plate protruding out of the feeding surface, and then the supporting plate moves down below the feeding surface to place the hopper on the feeding surface. At this time, the first conveying belt and the second conveying belt rotate in the opposite direction, so that the hopper can be fed away from the transfer gripper.

[0008] As a further improvement of the above technical solution, the first conveying part comprises a first conveying frame, a first synchronous wheel and a first motor.

The second conveying part comprises a second conveying frame, a second synchronous wheel and a second motor. The second conveying frame is slidingly connected to the feeding bottom plate and can move and position along the direction close to or away from the first conveying frame. A plurality of second synchronous wheels are rotationally connected to the second conveying frame, the second conveying belt is drivingly connected to the plurality of second synchronous wheels, the second motor is connected to the second conveying frame, and the second motor drivingly connects any one of the second synchronous wheels. The first conveying belt is supported and connected by the plurality of first synchronous wheels, so as to be rotationally connected to the first conveying frame. The first motor drives the first synchronous wheel to rotate, so as to drive the first conveying belt to rotate. Similarly, the second conveying belt is supported and connected by the plurality of second synchronous wheels, so as to be rotationally connected to the second conveying frame. The second motor drives the second synchronous wheel to rotate, so as to drive the second conveying belt to rotate. Thus, the two motors drive the two conveying belts to rotate synchronously, so as to realize the transfer of the hopper. When the size of the hopper to be fed or discharged changes, the second conveying frame can be slidingly adjusted. The distance between the first conveying belt and the second conveying belt is changed to adapt to the size of the hopper to be transferred.

The third translation driver can provide the transfer part with a translation driving force to approach or move away from the feeding device, and the third lifting driver can provide the transfer part with a driving force to move up and down.

Similarly, when it is needed to transfer the hopper from the discharging surface to the feeding surface, the third translation driver first drives the transfer part to move away from the feeding device, then the third lifting driver drives the transfer part to move up, and finally the third translation driver drives the transfer part to approach the feeding device, thereby transferring the hopper to the feeding surface.

[0010] As a further improvement of the above technical solution, the transfer part comprises a lower clamping plate, a clamping lifting driver and an upper clamping plate, the lower clamping plate and the clamping lifting driver are respectively connected to the lifting plate, and the clamping lifting driver is drivingly connected to the upper clamping plate. The clamping lifting driver can drive the upper clamping plate to approach or move away from the lower clamping plate. An area for clamping and fixing the material is formed between the upper clamping plate and the lower clamping plate. When it is needed to clamp and fix the material, the clamping lifting driver drives the upper clamping plate to approach the lower clamping plate, and at this time the upper clamping plate and the lower clamping plate clamp and fix the material. When it is needed to release the material, the clamping lifting driver drives the upper clamping plate to move away from the lower clamping plate, and at this time the upper clamping plate and the lower clamping plate release the material.

[0011] As a further improvement of the above technical solution, a rotating plate is rotatably connected to one side of the upper clamping plate away from the lifting plate, a torsional spring is arranged between the rotating plate and the upper clamping plate, and the torsional spring has a tendency to drive the rotating plate to rotate upward to be inclined relative to the upper clamping plate.

The first translation driver is connected to the first lifting driver, and the first lifting driver can drive the first translation driver to move up and down. The first translation driver is drivingly connected to the translation plate, and the first translation driver can drive the translation plate to move close to or away from the transfer part. The first material passing part and the second material passing part are respectively arranged on the translation plate, and the first material passing part and the second material passing part are respectively provided with the first conveyors.

The first translation driver can provide driving force for the first material passing part and the second material passing part to move in the direction of approaching or moving away from the material bin. When it is needed to take or place material from the material bin, the first translation driver drives the first material passing part and the second material passing part to approach the material bin. When it is needed to feed or discharge material to or from the work station outside, the first translation driver drives the first material passing part and the second material passing part to move away from the material bin.

When the size of the material changes, the first material passing part and the second material passing part can be adjusted to slide, the distance between the two first conveyors is changed to adapt to the size of the material to be transferred, and then the first material passing part and the second material passing part are repositioned, further improving the flexibility of the whole use.

[0014] As a further improvement of the above technical solution, the first material passing mechanism further comprises a material blocking part arranged between the first material passing part and the second material passing part. The material blocking part has a stopper that can move up and down. When the material moves close to the material bin on the first conveyor, the stopper of the material blocking part protrudes upward from the first conveyor, and can block and position the material.

[0030] As can be seen from the above, when conveying the materials, the feeding, discharging and transferring of the materials can be realized according to the needs, specifically, when feeding the materials, the material bin loaded with the materials is placed on the feeding surface 111 of the feeding mechanism 110, the feeding surface 111 transfers the material bin to the transferring part 210, the transferring part 210 tightly fixes the material bin, at this time, the materials can be transferred from the first transferring mechanism 310 or the second transferring mechanism 330 to the desired work station, for example, when feeding the first transferring mechanism 310, the second push rod 332 in the second transferring mechanism 330 moves to the material bin to push the materials in the material bin to the first conveyor 311 of the first transferring mechanism 310, and the first conveyor 311 sends the materials to the next work station, or when feeding the second transferring mechanism 330, the first push rod 312 in the first transferring mechanism 310 moves to the material bin to push the materials in the material bin to the second conveyor 331 of the second transferring mechanism 330, and the second conveyor 331 sends the materials to the next work station, when the feeding of the materials in the material bin is completed, the transferring part 210 transfers the material bin to the discharging surface 141 of the discharging mechanism 140, and the discharging surface 141 sends the material bin after the feeding is completed; when discharging the materials, the empty material bin is placed on the discharging surface 141 of the discharging mechanism 140, the discharging surface 141 sends the material bin to the transferring part 210, the transferring part 210 tightly fixes the material bin, at this time, the materials can be sent into the material bin from the first discharging surface 141 or the second discharging surface 141, and after the materials are moved out of the first discharging surface 141 and the second discharging surface 141, the first push rod 312 and the second push rod 332 further push the materials into the material bin to ensure that the materials are in place in the material bin, then the transferring part 210 transfers the material bin to the feeding surface of the feeding mechanism, and the feeding surface sends the material bin loaded with the materials; when transferring the materials, the material bin is fixed in the transferring part 210, at this time, the external materials can be sent into the first conveyor 311, then into the material bin, and then transferred from the material bin to the second conveyor 331, and then sent out of the second conveyor 331 to the external work station, or the external materials can be sent into the second conveyor 331, then into the material bin, and then transferred from the material bin to the first conveyor 311, and then sent out of the first conveyor 311 to the external work station. Thus, the feeding, discharging and transferring of the materials can be realized according to the needs, and the whole device has high versatility and is beneficial to improve the production efficiency.

[0031] The feeding mechanism 110 can be a single belt conveyor, and the feeding surface 111 is formed by the conveying belt of the belt conveyor, and in the embodiment, the feeding surface 111 is formed by the conveying belts of two belt conveyors. Figure 2 The feeding surface 111 of the feeding mechanism 110 can be formed by the conveying belts of two belt conveyors, and the conveying belts of the two belt conveyors are arranged in parallel. Figure 3As shown, the feeding mechanism 110 includes a feeding base plate 112, a first conveying part 120 and a second conveying part 130 arranged on the feeding base plate 112, and a material supporting part 150 between the first conveying part 120 and the second conveying part 130. The first conveying part 120 has a first conveying belt 121 capable of rotating movement, the second conveying part 130 has a second conveying belt 131 capable of rotating movement, the top side of the first conveying belt 121 and the top side of the second conveying belt 131 form the feeding surface 111, and the material supporting part 150 has a supporting plate 151 capable of moving up and down. When it is needed to feed the hopper to the transfer gripper, the hopper is placed on the top side of the first conveying belt 121 in the first conveying part 120 and the second conveying belt 131 in the second conveying part 130, when the first conveying belt 121 and the second conveying belt 131 rotate, the hopper is driven to move towards the transfer gripper, when the hopper moves above the supporting plate 151, the supporting plate 151 moves up to extend out of the feeding surface 111, and the hopper is supported away from the feeding surface 111, at this time, the transfer part 210 can clamp and fix the hopper. When the transfer gripper needs to feed the hopper to the feeding surface 111, the transfer gripper places the hopper on the supporting plate 151 which protrudes from the feeding surface 111, then the supporting plate 151 moves down below the feeding surface 111 to place the hopper on the feeding surface 111, at this time, the first conveying belt 121 and the second conveying belt 131 rotate reversely, and then the hopper can be sent away from the transfer gripper.

[0032] As a specific structural embodiment of the first conveying part 120 and the second conveying part 130, the first conveying part 120 comprises a first conveying frame 122, a plurality of first synchronous wheels 123 and a first motor 124, the first conveying frame 122 is connected to the feeding bottom plate 112, the plurality of first synchronous wheels 123 are rotationally connected to the first conveying frame 122, the first conveying belt 121 is drivingly connected with the plurality of first synchronous wheels 123, the first motor 124 is connected to the first conveying frame 122, and the first motor 124 is drivingly connected with any one of the first synchronous wheels 123. The second conveying part 130 comprises a second conveying frame 132, a plurality of second synchronous wheels 133 and a second motor 134, the second conveying frame 132 is slidingly connected to the feeding bottom plate 112, the second conveying frame 132 can be moved and positioned along the direction of approaching or moving away from the first conveying frame 122, the plurality of second synchronous wheels 133 are rotationally connected to the second conveying frame 132, the second conveying belt 131 is drivingly connected with the plurality of second synchronous wheels 133, and the second motor 134 is connected to the second conveying frame 132. The first motor 124 drives the first synchronous wheels 123 to rotate, thereby driving the first conveying belt 121 to rotate, and the second motor 134 drives the second synchronous wheels 133 to rotate, thereby driving the second conveying belt 131 to rotate. Thus, the two motors drive the two conveying belts to rotate synchronously, so as to realize the conveying of the silo. When the size of the silo needs to be changed, the second conveying frame 132 can be adjusted by sliding, the distance between the first conveying belt 121 and the second conveying belt 131 is changed to adapt to the size of the silo to be conveyed, and then the second conveying frame 132 is repositioned, thereby further improving the flexibility of the whole.

[0033] In actual application, the first conveying frame 122 can also be moved and positioned along the direction of approaching or moving away from the second conveying frame 132 on the feeding bottom plate 112. For example, a plurality of positioning holes are arranged on the feeding bottom plate 112 in the direction of moving away from the second conveying frame 132. After the first conveying frame 122 is adjusted to the position required to be installed, a screw is threaded on the first conveying frame 122 and connected to the opposite positioning hole, thereby realizing the positioning of the first conveying frame 122. For the second conveying frame 132, a locking screw can be threaded on the second conveying frame 132, and the end of the locking screw is pressed against the feeding bottom plate 112, thereby clamping the second conveying frame 132. When the position of the second conveying frame 132 needs to be adjusted, the locking screw is loosened.

[0034] Similarly, the discharge mechanism 140 can be a single belt conveyor, and the discharge surface 141 is formed by the belts of the belt conveyor. In the present embodiment, the discharge surface 141 is formed by the belts of two belt conveyors. Specifically, the discharge mechanism 140 includes a discharge base plate, a third conveying portion and a fourth conveying portion arranged on the discharge base plate, and a lifting portion between the third conveying portion and the fourth conveying portion. Since the discharge mechanism 140 has a similar structure to the feeding mechanism 110, the same reference numerals are not marked in the drawings. The discharge base plate is arranged below the feeding base plate 112, and the two are connected by support rods to form an integral whole. The third conveying portion has a third conveying belt that can rotate, the fourth conveying portion has a fourth conveying belt that can rotate, the top side of the third conveying belt and the top side of the fourth conveying belt form the discharge surface 141, and the lifting portion has a lifting plate that can move up and down. When the transfer gripper needs to feed the hopper, the hopper is placed on the top side of the third conveying belt and the fourth conveying belt in the third conveying portion, and when the third conveying belt and the fourth conveying belt rotate, the hopper is driven to move towards the transfer gripper. When the hopper moves above the lifting plate, the lifting plate moves up and extends out of the discharge surface 141, lifting the hopper away from the discharge surface 141, and at this time the transfer portion 210 can clamp and fix the hopper. When the transfer gripper needs to feed the hopper to the discharge surface 141, the transfer gripper places the hopper on the lifting plate that protrudes from the discharge surface 141, and then the lifting plate moves down below the discharge surface 141 to place the hopper on the discharge surface 141. At this time, the third conveying belt and the fourth conveying belt rotate in the opposite direction, and the hopper can be fed away from the transfer gripper.

[0035] Similarly, the distance between the third conveying part and the fourth conveying part can also be adjusted. Specifically, the third conveying part comprises a third conveying frame, third synchronous wheels and a third motor. The third conveying frame is connected to the discharge bottom plate. The third synchronous wheels are rotatably connected to the third conveying frame. The third conveying belt is drivingly connected to the third synchronous wheels. The third motor is connected to the third conveying frame. The third motor is drivingly connected to any one of the third synchronous wheels. The fourth conveying part comprises a fourth conveying frame, fourth synchronous wheels and a fourth motor. The fourth conveying frame is slidingly connected to the discharge bottom plate. The fourth conveying frame can move and be positioned along a direction close to or away from the third conveying frame. The fourth synchronous wheels are rotatably connected to the fourth conveying frame. The fourth conveying belt is drivingly connected to the fourth synchronous wheels. The fourth motor is connected to the fourth conveying frame. The fourth motor is drivingly connected to any one of the fourth synchronous wheels. The third conveying belt is rotatably connected to the third conveying frame through the third synchronous wheels. The third motor drives the third synchronous wheels to rotate, thereby driving the third conveying belt to rotate. Similarly, the fourth conveying belt is rotatably connected to the fourth conveying frame through the fourth synchronous wheels. The fourth motor drives the fourth synchronous wheels to rotate, thereby driving the fourth conveying belt to rotate. The two motors drive the two conveying belts to rotate synchronously, thereby achieving the conveying of the silo. When the size of the silo to be conveyed changes, the fourth conveying frame can be adjusted to change the distance between the third conveying belt and the fourth conveying belt, thereby adapting to the size of the silo to be conveyed. Then, the fourth conveying frame is repositioned, thereby further improving the flexibility of the whole device.

[0036] The transfer device 200 has a driving structure for driving the transfer part 210 to move back and forth. Specifically, as shown in Figure 4As shown, the transfer device 200 comprises a third translation driver 220, a third lifting driver 230 connected to the third translation driver 220, and a lifting plate 240, the third translation driver 220 can drive the third lifting driver 230 to approach or move away from the feeding device 100, the third lifting driver 230 is drivingly connected to the lifting plate 240, and the third lifting driver 230 can drive the lifting plate 240 to move up and down, and the transfer part 210 is connected to the lifting plate 240. In actual application, the third translation driver 220 and the third lifting driver 230 are respectively used to provide driving force for reciprocating movement in a straight line, and there are various structural forms, for example, a pneumatic cylinder, an electric screw or a hydraulic cylinder can be used. The third translation driver 220 can provide the transfer part 210 with translation driving force for approaching or moving away from the feeding device 100, and the third lifting driver 230 can provide the transfer part 210 with driving force for moving up and down. When it is needed to transfer the hopper from the feeding surface to the discharging surface 141, the third translation driver 220 first drives the transfer part 210 to move away from the feeding device 100, then the third lifting driver 230 drives the transfer part 210 to move down, and finally the third translation driver 220 drives the transfer part 210 to approach the feeding device 100, thereby transferring the hopper to the discharging surface 141. Similarly, when it is needed to transfer the hopper from the discharging surface 141 to the feeding surface, the third translation driver 220 first drives the transfer part 210 to move away from the feeding device 100, then the third lifting driver 230 drives the transfer part 210 to move up, and finally the third translation driver 220 drives the transfer part 210 to approach the feeding device 100, thereby transferring the hopper to the feeding surface.

[0037] The transfer part 210 can adopt a clamping structure that can be opened and closed, such as a pneumatic clamping jaw or an electric clamping jaw. In the present embodiment, the transfer part 210 comprises a lower clamping plate 211, a clamping lifting driver 212, and an upper clamping plate 213, the lower clamping plate 211 and the clamping lifting driver 212 are respectively connected to the lifting plate 240, the clamping lifting driver 212 is drivingly connected to the upper clamping plate 213, and the clamping lifting driver 212 can drive the upper clamping plate 213 to approach or move away from the lower clamping plate 211. In actual application, the clamping lifting driver 212 is used to provide driving force for reciprocating movement in a straight line, and there are various structural forms, for example, a pneumatic cylinder, an electric screw or a hydraulic cylinder can be used. The upper clamping plate 213 and the lower clamping plate 211 form a region for clamping and fixing materials. When it is needed to clamp and fix materials, the clamping lifting driver 212 drives the upper clamping plate 213 to approach the lower clamping plate 211, at this time, the upper clamping plate 213 and the lower clamping plate 211 clamp and fix materials. When it is needed to release materials, the clamping lifting driver 212 drives the upper clamping plate 213 to move away from the lower clamping plate 211, at this time, the upper clamping plate 213 and the lower clamping plate 211 release materials.

[0038] Furthermore, a rotating plate 214 is rotatably connected to the side of the upper clamping plate 213 away from the lifting plate 240. A torsion spring 215 is provided between the rotating plate 214 and the upper clamping plate 213. The torsion spring 215 has the tendency to drive the rotating plate 214 to rotate upward to tilt relative to the upper clamping plate 213. Because the rotating plate 214 has gravity, in its natural state, the rotating plate 214 rotates to a vertical position. Due to the external force applied to the rotating plate 214 by the torsion spring 215, when it is not necessary to clamp and fix the hopper, the torsion spring 215 drives the rotating plate 214 to rotate upward, so that the rotating plate 214 is tilted relative to the upper clamping plate 213. When it is necessary to clamp and fix the hopper, the upper clamping plate 213 moves downward. At this time, the rotating plate 214 abuts against the top side of the hopper, so that the rotating plate 214 rotates upward until it abuts against the upper clamping plate 213. At this time, the torsion spring 215 is elastically compressed, which can provide a horizontal thrust to the hopper, making the clamping of the hopper between the upper clamping plate 213 and the lower clamping plate 211 more stable.

[0039] like Figure 5 As shown, as a specific structural embodiment of the first material conveying mechanism 310, the first material conveying mechanism 310 includes a first lifting driver 313, a first translation driver 314, a translation plate 315, a first material conveying section 316, and a second material conveying section 317. The first translation driver 314 is connected to the first lifting driver 313, and the first lifting driver 313 can drive the first translation driver 314 to move up and down. The first translation driver 314 is connected to the translation plate 315, and the first translation driver 314 can drive the translation plate 315 to move closer to or away from the transfer section 210. The first material conveying section 316 and the second material conveying section 317 are respectively disposed on the translation plate 315. The first conveyor 311 is respectively disposed in the first material conveying section 316 and the second material conveying section 317. In practical applications, the first lifting driver 313 and the second lifting driver 312 are respectively used to provide driving force for reciprocating movement in a straight direction. Their structural forms are various, for example, cylinders, electric screws, or hydraulic cylinders can be used. The first lifting drive 313 can provide the first conveying part 316 and the second conveying part 317 with the driving force to move up and down, which can adapt to the feeding of hoppers of different heights. The first translation drive 314 can provide the first conveying part 316 and the second conveying part 317 with the driving force to move in the direction of approaching or moving away from the hopper. When it is necessary to pick up or put down materials from the hopper, the first translation drive 314 drives the first conveying part 316 and the second conveying part 317 to move closer to the hopper. When it is necessary to load or unload materials to an external workstation, the first translation drive 314 drives the first conveying part 316 and the second conveying part 317 away from the hopper.

[0040] The first conveyor 311 within the first conveying section 316 and the second conveying section 317 can be a belt conveyor or a wheel conveyor. To easily adapt to different material sizes, in this embodiment, the first conveying section 316 and the second conveying section 317 can be adjusted and positioned on the translation plate 315 in a direction that moves closer to or further away from each other. In practical applications, a locking screw can be inserted into the first conveying section 316, and the end of the locking screw can be used to press against the translation plate 315, thereby pressing and positioning the first conveying section 316. When it is necessary to slide and adjust the first conveying section 316 again, the locking screw can be loosened. Similarly, the adjustment and positioning of the second conveying section 317 is also positioned in the same way. When the size of the material changes, the first conveying section 316 and the second conveying section 317 can be slidably adjusted. By changing the distance between the two first conveyors 311, the size of the material to be transferred can be adapted. Then, the first conveying section 316 and the second conveying section 317 can be repositioned, further improving the overall flexibility of use.

[0041] In order to better control the travel of the material on the first conveyor 311, in this embodiment, the first feeding mechanism 310 further includes a baffle 318 disposed between the first feeding section 316 and the second feeding section 317. The baffle 318 has a stop 319 that can move up and down. Naturally, a drive source for driving the stop 319 to move up and down can also be provided in the first feeding mechanism 310. The drive source can be connected to the translation plate 315, the fixed structure of the first feeding section 316 or the fixed structure of the second feeding section 317, and can be an electric screw, a cylinder or a hydraulic cylinder, etc. The stop 319 can be rod-shaped or block-shaped. When the material moves toward the hopper on the first conveyor 311, the stop 319 of the baffle part 318 protrudes upward from the first conveyor 311 to block and limit the material. When it is necessary to send the stop 319 out of the first conveyor 311, the stop 319 moves downward to below the first conveyor 311, which can improve the accuracy of feeding the material into the hopper.

[0042] Furthermore, the first material handling mechanism 310 also includes a first base 320, a second translation driver 321, and a second lifting driver 322. The first base 320 is connected to the translation plate 315, the second translation driver 321 is connected to the first base 320, and the second lifting driver 322 is connected to the second translation driver 321. The second translation driver 321 can drive the second lifting driver 322 to move closer to or further away from the transfer part 210. The second lifting driver 322 is connected to the first push rod 312 and can drive the first push rod 312 to move up and down. The first translation driver 314 provides a driving force to the first push rod 312 to move in the direction of approaching or moving away from the hopper, while the second lifting driver 322 drives the first push rod 312 to move up and down. When the material on the first conveyor 311 moves into the hopper, the second lifting driver 322 can drive the first push rod 312 to move down to face the material. Then the second translation driver 321 drives the first push rod 312 to move further into the hopper and push the material into the hopper.

[0043] like Figure 7 As shown, the second translation actuator 321 and the second lifting actuator 322 are used to provide driving force for reciprocating movement in a linear direction. Their structural forms are varied, such as cylinders, hydraulic cylinders, or electric lead screws. In this embodiment, the second translation actuator 321 includes a translation base 323, a synchronous belt 324, a transmission wheel 325, and a fifth motor. Two transmission wheels 325 are rotatably connected to the first base 320. The synchronous belt 324 is driven between the two transmission wheels 325. The fifth motor drives either transmission wheel 325. The translation base 323 is slidably connected to the first base 320, and one side of the translation base 323 is fixedly connected to the synchronous belt 324. During operation, the fifth motor drives the synchronous belt 324 to rotate via the transmission wheel 325, thereby causing the translation base 323 to slide. The second lifting actuator 322 includes a sixth motor 326, an output wheel, and a lifting base 328. The lifting base 328 is slidably connected to the translation base 323 in the vertical direction. The sixth motor 326 is connected to the lifting base 328 and drives the output wheel. An output shaft 327 is eccentrically connected to the output wheel. The lifting base 328 is provided with a transmission groove 329 extending in the horizontal direction. The output shaft 327 extends into the transmission groove 329. A first push rod 312 is connected to the lifting base 328. During operation, the sixth motor 326 drives the output wheel to rotate. At this time, the output shaft 327 rotates around the axis of the output wheel and transmits the torque for vertical movement to the lifting base 328, thereby driving the lifting base 328 to move up and down.

[0044] like Figure 6As shown in the diagram, as a specific structural embodiment of the second material conveying mechanism 330, the second material conveying mechanism 330 includes a fourth lifting drive 333, a movable plate 334, a third material conveying section 335, and a fourth material conveying section 336. The fourth lifting drive 333 is drively connected to the movable plate 334, and can drive the movable plate 334 to move up and down. The third material conveying section 335 and the fourth material conveying section 336 are respectively disposed on the movable plate 334. The second conveyor 331 is respectively disposed in the third material conveying section 335 and the fourth material conveying section 336. In practical applications, the fourth lifting drive 333 is used to provide the driving force for reciprocating movement in a straight direction. Its structural form can be various, for example, it can be a cylinder, an electric screw, or a hydraulic cylinder. When it is necessary to pick up or drop material from the hopper, the material can enter and exit between the two second conveyors 331. When it is necessary to load or unload material to an external workstation, the two second conveyors 331 can transport the material to the external workstation.

[0045] The second conveyors 331 within the third and fourth conveyor sections 335 and 336 can be belt conveyors or wheel conveyors. In this embodiment, the third and fourth conveyor sections 335 and 336 can be adjusted and positioned relative to each other on the movable plate 334. In practical applications, locking screws can be installed on the third conveyor section 335, with the ends of the screws pressing against the movable plate 334 to secure the third conveyor section 335. When further adjustment of the third conveyor section 335 is needed, the locking screws can be loosened. Similarly, the adjustment and positioning of the fourth conveyor section 336 can be done in the same way. When the size of the material changes, the third and fourth conveyor sections 335 and 336 can be slidably adjusted by changing the distance between the two second conveyors 331 to accommodate the size of the material to be conveyed. Then, the third and fourth conveyor sections 335 and 336 can be repositioned, further improving the overall flexibility of use.

[0046] Furthermore, the second feeding mechanism 330 also includes a second base 337, a fourth translation driver 338, and a fifth lifting driver 339. The second base 337 is connected to the fixed structure of the third feeding part 335 or the fourth feeding part 336. The fifth lifting driver 339 is connected to the second base 337. The fourth translation driver 338 is connected to the fifth lifting driver 339. The fifth lifting driver 339 can drive the fourth translation driver 338 to move up and down. The fourth translation driver 338 is connected to the second push rod 332. The fourth translation driver 338 can drive the second push rod 332 to move closer to or away from the transfer part 210. In practical applications, the fourth translation driver 338 and the fifth lifting driver 339 are used to provide driving force for reciprocating movement in a straight direction. Their structural forms are various, such as cylinders, hydraulic cylinders, or electric lead screws. The fourth translational driver 338 provides a driving force to the second push rod 332 to move in the direction of approaching or moving away from the hopper, while the fifth lifting driver 339 drives the second push rod 332 to move up and down. When the material on the second conveyor 331 moves into the hopper, the fifth lifting driver 339 can drive the second push rod 332 to move down to face the material, and then the fourth translational driver 338 drives the second push rod 332 to move further into the hopper, pushing the material into the hopper.
