In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0020] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0021] Combine the following Figures 1 to 8 , the automatic weight sorting machine 100 provided in the embodiment of the present application is described in detail through a specific embodiment.

[0022] Please also refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , Figure 1 It is a structural schematic diagram of the automatic weight sorting machine provided by the present invention; Figure 2 is a structural schematic diagram of an automatic weight sorting machine provided by another embodiment of the present invention; Figure 3 It is a schematic diagram of the assembly of the frame and weighing device of the automatic weight sorting machine provided by the present invention; Figure 4 yes Figure 3 The enlarged schematic diagram at A in the middle; Figure 5 It is an assembly diagram of the lifting device and the material guiding device of the automatic weight sorting machine provided by the present invention. The automatic weight sorting machine 100 provided by one embodiment of the present invention includes a frame 10, a weighing device 20 and a feeder 200. A plurality of material boxes 70 may be arranged on the frame 10, and the plurality of material boxes 70 are used to collect the weighed materials. A weighing platform 12 is arranged at the upper end of the frame 10, and the weighing platform 12 is used to place the weighing device 20; and a supporting frame 11 is arranged on at least one side of the frame 10, and the height of the supporting frame 11 is lower than the height of the weighing platform 12, and a material box 70 may be arranged on the supporting frame 11. Since the height of the supporting frame 11 is lower than the height of the weighing platform 12, and the height of the material box 70 is lower than the height of the weighing platform 12, after the weighing device 20 on the weighing platform 12 weighs the material, the material can fall into the material box 70. The weighing device 20 is arranged on the weighing platform 12 of the frame 10. The weighing device 20 includes a plurality of weighing devices 21 and a ring conveyor line 22. The ring conveyor line 22 is operably arranged on the frame 10. A plurality of weighing devices 21 are arranged in sequence on the ring conveyor line 22 at intervals. The ring conveyor line 22 is used to drive the weighing devices 21 to move in a cycle. The weighing device 21 includes a weighing plate 211 with a mouth 212. The weighing device 21 can flip the weighed material through the weighing plate 211 and drop it into each corresponding material box 70 through its mouth 212. The loader 200 can be arranged on both sides of the frame 10, or can be arranged on one side of the frame 10. The loader 200 is used to transport multiple materials and load the materials one by one into the weighing plate 211.

[0023] The support frame 11 is located on at least one side of the frame 10, and the height of the support frame 11 is lower than the height of the weighing platform 12. The material box 70 placed on the support frame 11 is used to receive the weighed and sorted materials. At this time, the material box 70 can be directly placed on the support frame 11 with a lower height, which is convenient for taking and placing.

[0024] The loader 200 is arranged at at least one end of the frame 10, and is used to transport and load materials one by one; the sorting conveyor belt 41 is arranged at the discharge end of the lifting device 30 and the loading end of the sorting conveyor belt 41 is at least partially located on the top of the weighing device 20, and the material guide component is used to guide the materials falling through the lifting device 30 for sorting and loading them one by one to the weighing device 20, and a plurality of weighing devices 21 can be circulated on the frame 10 to sequentially receive the materials falling one by one through the sorting conveyor belt 41.

[0025] A plurality of weighing devices 21 are sequentially arranged at intervals on the annular conveyor line 22, which can realize continuous weighing operation and improve sorting efficiency. When one material is weighed, the next weighing device 21 can quickly arrive at the position to receive the new material, thus reducing waiting time.

[0026] It should be noted that the circular conveyor line 22 can rotate, thereby driving the weighing device 21 on the circular conveyor line 22 to move synchronously, thereby realizing the continuous weighing operation of the weighing device 21. Among them, a driving device can be provided at the bottom of the circular conveyor line 22, and the circular conveyor line 22 is driven to move by the driving device. The driving device can adopt a common motor available on the market, and the circular conveyor line 22 usually adopts the existing transmission chain form, which will not be described in detail here.

[0027] The provision of the annular conveyor line 22 can make the movement of the weighing device 21 more stable and orderly, ensuring the accuracy of the weighing process. The weighing device 21 circulates on the annular conveyor line 22, reducing the floor space of the equipment and making the overall structure more compact.

[0028] The feeder 200 can accurately guide the material to the weighing device 21 of the weighing device 20. This avoids the scattering and deviation of the material during the falling process, ensures that the material can accurately fall on the weighing device 21, and further improves the accuracy of weighing.

[0029] In this embodiment, the materials are transported one by one by the feeder 200, and the materials are accurately guided to the weighing device 20, and multiple weighing devices 21 perform continuous weighing operations, so as to weigh and sort the materials, and then the weighing device 21 can pour the weighed materials into the material box 70 through the mouth 212 on the weighing plate 211. Through such a setting, there is no need for manual sorting, weighing and sorting, which improves work efficiency, and the materials are transported one by one to the weighing device 21 for weighing, which improves the sorting accuracy, so that the quality of the materials can be well guaranteed.

[0030] See also Figure 4In some embodiments, the frame 10 includes a centrifugal shield 50, and the centrifugal shield 50 is disposed at at least one end of the frame 10, the mouth 212 of the weighing plate 211 is disposed toward the outside, and the centrifugal shield 50 is disposed around the mouths 212 of the plurality of weighing plates 211 running to the end of the frame 10 to prevent the material in the weighing plate 211 from being thrown out through its mouth 212 under the centrifugal force of the operation of the annular conveyor line 22.

[0031] When the weighing device 21 moves on the circular conveyor line 22, especially when the weighing device 21 moves at a fast speed or at a turning point, the centrifugal force is large, and the material may be thrown out from the mouth 212 of the weighing device 21 due to the centrifugal force. The centrifugal shield 50 can effectively block the material. When the material is about to be thrown out, the centrifugal shield 50 can block the material. This ensures that the material is always stably placed on the weighing device 21, ensuring the accuracy of the weighing result. At the same time, it also avoids the damage and interference caused by the falling material to the equipment and the surrounding environment.

[0032] Among them, the centrifugal shield 50 can be used as basic protection, and is directly set at both ends of the weighing platform 12, which can prevent the material from accidentally falling from both ends of the weighing platform 12 to a large extent. This provides the first guarantee for the stable placement of the material, ensuring that during normal operation, even if there are some slight shaking or unexpected situations, the material is not easy to roll directly from the edge of the weighing platform 12. In addition, the centrifugal shield 50 can also be tilted toward the weighing device 21, and the centrifugal shield 50 corresponds to the mouth 212 of the weighing device 21, so that the centrifugal shield 50 can effectively block the material and prevent the material from being thrown out from the mouth 212 of the weighing device 21.

[0033] See also Fig.10 , Fig.10 It is a structural schematic diagram of the material temporary storage device of the automatic weight sorting machine provided by the present invention. In some embodiments, it also includes a plurality of material temporary storage devices 80, and the plurality of material temporary storage devices 80 are respectively arranged between the weighing platform 12 and the supporting frame 11, so that the material flipped and fallen by the weighing plate 211 can fall into the corresponding material box 70 through the corresponding material temporary storage device 80; wherein, the material temporary storage device 80 includes a material receiving channel 81, a supporting component 82 and a driving component 83, and the upper and lower ends of the material receiving channel 81 are both open; the supporting component 82 can be movably arranged at the opening of the lower end of the material receiving channel 81 to realize opening or closing the opening of the lower end of the material receiving channel 81; the driving component 83 is telescopically arranged between the material receiving channel 81 and the supporting component 82, and the driving component 83 can be telescopic to drive the supporting component 82 to move so as to open or close the opening of the lower end of the material receiving channel 81.

[0034] The material temporary storage device 80 also includes a limit assembly 84, which is arranged on the lower end side wall of the material receiving channel. The limit assembly 84 and the supporting assembly 82 abut against each other so that the supporting assembly 82 can remain positioned in a closed state, and the limit assembly 84 can elastically retract so that the supporting assembly 82 can move to open the opening at the lower end of the material receiving channel.

[0035] The upper and lower ends of the receiving channel 81 are both opened. After the automatic weight sorting machine 100 weight-sorts the material (such as abalone), the material on the automatic weight sorting machine 100 can be poured onto the material box 70. When the material falls into the material box 70, the material first enters the receiving channel 81 through the opening at the upper end of the receiving channel 81, and then goes out from the opening at the lower end of the receiving channel 81, and then falls onto the material box 70. Specifically, the receiving channel 81 is arranged in a substantially vertical direction, so that the receiving channel 81 is adapted to the trajectory of the material falling by its own gravity.

[0036] The supporting assembly 82 is movably arranged at the lower end of the receiving channel 81 so as to close the opening at the lower end of the receiving channel. When the material passes through the receiving channel 81, the material can enter the receiving channel 81 through the opening above the receiving channel 81, and then the supporting assembly 82 closes the lower end opening of the receiving channel 81. At this time, the driving assembly 83 abuts against the supporting assembly 82 to limit the movement of the supporting assembly 82 in the receiving channel 81. At this time, the supporting assembly 82 can prevent the material in the receiving channel 81 from falling. Through such a setting, when the worker needs to take out or replace the fully loaded material box 70, the material can be temporarily collected through the receiving channel 81 and the supporting assembly 82 to prevent the material from falling through the receiving channel 81, and the automatic weight sorting machine 100 does not need to be closed to reduce the sorting efficiency, which is convenient to use. Then, as more materials are collected on the supporting component 82, the pressure generated by the materials on the supporting component 82 becomes greater. At this time, the supporting component 82 will generate a force on the limiting component 84 to compress and retract the limiting component 84. At this time, the limiting component 84 gradually moves away from the supporting component 82, and the supporting component 82 is no longer subjected to the abutment force from the limiting component 84. At this time, the supporting component 82 can move on the material receiving channel 81, so that the lower end opening of the material receiving channel 81 can be opened, and then the material falls into the material box 70 which is replaced under the material receiving channel 81.

[0037] Regarding the above-mentioned driving assembly 83, the driving assembly 83 is telescopically arranged between the material receiving channel 81 and the supporting assembly 82. The driving assembly 83 can be telescopically arranged to drive the supporting assembly 82 to move in the material receiving channel 81, so that the supporting assembly 82 closes the lower opening of the material receiving channel 81. Through such an arrangement, when the lower opening of the material receiving channel 81 is opened and the material box 70 under the material receiving channel 81 is taken away, the supporting assembly 82 can be driven to move by the driving assembly 83, so that the supporting assembly 82 blocks the lower opening of the material receiving channel 81.

[0038] In some embodiments, one end of the supporting assembly 82 is rotatably connected to the lower end of the material receiving channel 81, and an abutment seat 85 is provided at the bottom of the supporting assembly 82, so that the telescopic rod 831 of the driving assembly 83 abuts against the abutment seat 85 to push the supporting assembly 82 to rotate and close the opening at the lower end of the material receiving channel 81.

[0039] After the supporting assembly 82 is located in the material receiving channel 81 and closes the lower opening of the material receiving channel 81, the driving assembly 83 can drive the telescopic rod 831 to approach the supporting assembly 82 and contact the abutment seat 85 of the supporting assembly 82, thereby pushing the supporting assembly 82 to rotate to close the opening at the lower end of the material receiving channel 81.

[0040] The driving assembly 83 is connected to the telescopic rod 831, and the driving assembly 83 can drive the telescopic rod 831 to move close to or away from the supporting assembly 82. When the position of the supporting assembly 82 needs to be adjusted, the driving assembly 83 drives the telescopic rod 831 to approach the supporting assembly 82, so that the telescopic rod 831 abuts against the abutment seat 85, and then the telescopic rod 831 can drive the supporting assembly 82 to rotate toward the inner wall of the material receiving channel 81 to close the lower opening of the material receiving channel 81. When the supporting assembly 82 is adjusted to its position, the driving assembly 83 can drive the telescopic rod 831 to move away from the supporting assembly 82 and separate from the abutment seat 85. Through such a setting, the rotation of the supporting assembly 82 can be realized, thereby facilitating the position adjustment of the supporting assembly 82.

[0041] In some embodiments, the automatic weight sorting machine 100 also includes a material receiving device 60, which is arranged between the loading end of the loader 200 and the weighing platform 12, so that the material falling from the loading end of the loader 200 can fall into the corresponding weighing plate 211 through the material receiving device 60.

[0042] The material receiving device 60 includes a mounting seat 61 and a hopper 63, the mounting seat 61 is arranged on the frame 10, and the hopper 63 is adjustably arranged on the mounting seat 61, so that the distance or relative position between the hopper 63 and the loading end of the loader 200 can be adjusted, and the upper and lower ends of the hopper 63 are both through-set, so that the material falling from the loading end of the loader 200 can fall into the corresponding weighing plate 211 through the hopper 63.

[0043] The material receiving device 60 includes a mounting seat 61 and a hopper 63. The mounting seat 61 is arranged on the frame 10. The hopper 63 includes a connecting plate 62. One end of the connecting plate 62 is slidably connected to the mounting seat 61, and the hopper 63 is connected to the other end of the connecting plate 62. When the material falls onto the weighing device 21 through the discharge end of the feeder 200, the material first passes through the hopper 63. By providing the hopper 63, when the material passes through the hopper 63, the inner wall of the hopper 63 can guide the material, preventing the material from not being accurately dropped on the weighing device 21 due to its own too fast falling speed and small or large falling angle.

[0044] Among them, the hopper 63 is rotatably mounted on the mounting seat 61 through a rotating shaft, so that the hopper 63 can rotate relative to the mounting seat 61 to adjust the position of the hopper 63 or adjust the distance between the hopper 63 and the loading end of the loader 200, so that the material falling from the loading end of the loader 200 can be smoothly dropped into the corresponding weighing plate 211 through the hopper 63, thereby improving the practicality and reliability of the sorting machine.

[0045] Furthermore, by slidingly connecting the connecting plate 62 on the mounting base 61 , the position of the hopper 63 can be adjusted according to the volume of the material and the speed of movement of the material, so that the hopper 63 remains corresponding to the material and the weighing device 21 , so that the material can fall accurately onto the weighing device 21 .

[0046] Specifically, a third strip-shaped hole 611 may be opened on the mounting seat 61 , and the connecting plate 62 may be fixed in the third strip-shaped hole 611 by bolts or screws.

[0047] In some embodiments, the feeder 200 includes a feeder rack 312, a lifting device 30, and a sorting conveyor belt 41. The feeder rack 312 is provided with a receiving cavity; the lifting device 30 includes a conveyor belt 311, the conveyor belt 311 is tiltedly arranged on the feeder rack 312, and the lower end of the conveyor belt 311 extends into the receiving cavity, and a plurality of rows of pallet assemblies 3111 are arranged at intervals on the belt surface of the conveyor belt 311; the sorting conveyor belt 41 is arranged on the feeder rack 312, and the first end of the sorting conveyor belt 41 is arranged corresponding to the upper end of the conveyor belt 311, and a plurality of flow guide members 42 are arranged above the sorting conveyor belt 41, and the plurality of flow guide members 42 are arranged in a staggered interval from the first end to the second end of the sorting conveyor belt 41, so that the plurality of materials transported by the conveyor belt 311 to the first end of the sorting conveyor belt 41 pass through the plurality of flow guide members 42 in sequence and are loaded one by one at the second end of the sorting conveyor belt 41.

[0048] The conveyor belt 311 is tilted, specifically, tilted toward the loading rack 312. When materials are being transported on the conveyor belt 311, the conveyor belt 311 moves upward. At this time, the conveyor belt 311 is tilted, so that the pallet assembly 3111 on the conveyor belt 311 can be tilted relative to the loader 200, thereby preventing the materials on the pallet assembly 3111 from falling, and allowing the materials on the pallet assembly 3111 to be smoothly transported to the material guide assembly.

[0049] The pallet assembly 3111 provides a stable placement platform for the material, preventing the material from sliding due to the vibration or slope of the conveyor belt 311 during the conveying process, ensuring that the material can be safely and reliably conveyed to the next link. When the material is conveyed on the conveying group, specifically, the material is placed on the pallet assembly 3111, and the conveyor belt 311 drives the pallet assembly 3111 to move upward, and then the pallet assembly 3111 drives the material to move upward to realize the transportation of the material.

[0050] Furthermore, the multiple pallet assemblies 3111 are spaced apart from each other, and the multiple pallet assemblies 3111 can separate the materials to prevent mutual interference and overlap between the materials on adjacent pallet assemblies 3111, which is beneficial for the subsequent screening assembly 32 to perform screening work more effectively and improve the accuracy and efficiency of screening.

[0051] The sorting conveyor belt 41 is arranged at the discharge end of the lifting device 30, and a plurality of guide components 42 are staggered and spaced from the first end to the second end of the sorting conveyor belt 41, so that the plurality of materials transported to the first end of the sorting conveyor belt 41 by the conveyor belt 311 pass through the plurality of guide components 42 in sequence and are loaded one by one at the second end of the sorting conveyor belt 41.

[0052] A plurality of guide components 42 are arranged above the sorting conveyor belt 41, and the plurality of guide components 42 are staggered and spaced in sequence from the first end to the second end of the sorting conveyor belt 41, so that the plurality of materials transported by the conveyor belt 311 to the first end of the sorting conveyor belt 41 pass through the plurality of guide components 42 in sequence and are loaded one by one at the second end of the sorting conveyor belt 41. In this way, through the guiding and sorting effect of the plurality of guide components 42, the individual abalone or materials scattered and falling from the upper end of the conveyor belt 311 are gradually and orderly arranged in a row one by one, and slide down one by one at the end of the sorting conveyor belt 41, so that the individual abalone or materials can be loaded, weighed and sorted one by one, avoiding the inaccurate weighing and sorting of materials caused by loading multiple materials each time, so as to improve the practicality and accuracy of the loading machine 200.

[0053] A guide channel is formed between the multiple guide components 42, and the width of the mouth 212 of the guide channel close to the conveyor belt 311 is greater than the width of the mouth 212 of the guide channel away from the conveyor belt 311, and the two adjacent guide components 42 on the left and right are roughly arranged in an "eight" shape.

[0054] The guide component 42 includes a bracket 421 arranged above the sorting conveyor belt 41 and a guide plate 422 arranged on the bracket 421. The plate surface of the guide plate 422 is arranged roughly perpendicular to the sorting conveyor belt 41. In this way, the material on the sorting conveyor belt 41 can be transported along the guide plate 422 and loaded one by one at the second end of the sorting conveyor belt 41.

[0055] In another embodiment, the guide component 42 includes a bracket 421 arranged above the sorting conveyor 41 and a guide sorting conveyor 41 arranged on the bracket 421. The guide sorting conveyor 41 is arranged approximately perpendicular to the sorting conveyor 41, and the inner surface of the guide sorting conveyor 41 is arranged to run from the first end to the second end of the sorting conveyor 41, so that the guide plate 422 is replaced by the guide sorting conveyor 41. In this way, under the operation of the guide sorting conveyor 41, the materials on the sorting conveyor 41 are transported along the running direction of the guide sorting conveyor 41 and loaded one by one at the second end of the sorting conveyor 41, so as to avoid the accumulation of materials on the sorting conveyor 41 due to the blocking of the guide component 42, thereby further improving the smoothness and stability of the operation of the loader 200.

[0056] Among them, the sorting conveyor belt 41 and the conveyor belt 311 are driven by a driving motor, and the specific structure and principle of their operation and conveying materials are existing technologies, as well as the weighing structure and principle of the weighing device 20, and the structure and principle of driving the weighing plate 211 to flip and pour out the sorted materials are all existing technologies, so they will not be repeated here.

[0057] See also Figure 5In some embodiments, the feeder 200 includes a screening component 32, which is disposed on the upper portion of the conveyor belt 311, and is used to knock down and screen a plurality of overlapping materials on the conveyor belt 311; The screening component 32 can screen multiple overlapping materials on the conveyor belt 311, avoiding the problem of inaccurate weighing caused by overlapping materials, ensuring that only a single material enters the subsequent weighing and sorting process, and improving the sorting accuracy.

[0058] The conveyor belt 311 can automatically transport the material to the discharge end of the lifting device 30, and make the material move on the lifting device 30 and fall to the sorting conveyor belt 41, and then the sorting conveyor belt 41 guides the material to the weighing device 21 of the weighing device 20, thereby saving labor costs and improving loading efficiency.

[0059] Specifically, in this embodiment, the material is placed on the loading rack 312. Since the conveyor belt 311 is tilted and arranged on the loading rack 312, and one end is slidably connected to the loading rack 312, the conveyor belt 311 drives the pallet assembly 3111 to move synchronously during operation. The material can move upward along the inclined conveyor belt 311 through the pallet assembly 3111. During the conveying process, the pallet assembly 3111 separates the materials so that a certain distance is maintained between the materials to avoid overlapping. As the conveyor belt 311 continues to move, the materials are stably conveyed to the screening assembly 32. The screening assembly 32 screens the conveyed materials. Since the volume of the overlapping materials is larger than that of a single material, the overlapping materials can be knocked down by the screening material during the movement, ensuring that only a single qualified material enters the subsequent loading machine 200 and the weighing device 20 for sorting operations.

[0060] Both ends of the conveyor belt 311 are arranged on the loading rack 312, and one end is rotatably connected to the loading rack 312, and the other end is slidably connected to the loading rack 312. Through such an arrangement, the inclination angle of the conveyor belt 311 can be adjusted so that the inclination angle of the conveyor belt 311 can adapt to the position of the screening assembly 32. Specifically, one end of the conveyor belt 311 can slide on the loading rack 312, and the other end of the conveyor belt 311 can rotate, and the inclination angle of the conveyor belt 311 is adjusted.

[0061] Please also read Figure 5 , Figure 6 and Figure 7 , Figure 6 yes Figure 5 The enlarged schematic diagram of point B in the middle; Figure 7 yes Figure 5The enlarged schematic diagram is shown at C in the middle. In some embodiments, the screening assembly 32 includes a baffle plate 322 and a first adjustment plate 3212. The first adjustment plate 3212 is disposed on both sides of the conveyor belt 311. Both ends of the baffle plate 322 are slidably connected to the first adjustment plate 3212, respectively. There is a certain gap between the baffle plate 322 and the conveyor belt 311. The baffle plate 322 can slide on the first adjustment plate 3212 to adjust the gap between the baffle plate 322 and the conveyor belt 311.

[0062] When multiple materials are stacked together and conveyed upward on the same pallet assembly 3111, due to the large sum of the external volumes of the multiple materials, they will generally exceed the edge of the pallet assembly 3111 and expose more parts. During the operation of the automatic weight sorting machine 100, the materials are conveyed to the screening assembly 32 by the conveyor belt 311. There is a certain gap between the baffle plate 322 and the conveyor belt 311. When the materials pass through, the materials with a size smaller than the gap can smoothly pass through the gap between the baffle plate 322 and the pallet assembly 3111 and continue to be conveyed to the subsequent process; while the materials with a size larger than the gap are blocked by the baffle plate 322, so that the multiple stacked materials fall off the pallet assembly 3111, which can avoid the multiple stacked materials from being fed together for weighing and sorting and affecting the practicality and accuracy of the feeder 200, thereby improving the accuracy of weighing and sorting. It can be applied to a variety of different materials for feeding, with a wide range of applications and easy use.

[0063] If the gap size needs to be adjusted, the staff can push the baffle plate 322 to slide on the first adjustment plate 3212 manually or automatically. Adjust the gap to a suitable size according to the size requirements of the material. During the adjustment process, the baffle plate 322 always remains parallel to the conveyor belt 311 to ensure the accuracy of the screening. After the adjustment is completed, the equipment continues to run, and the baffle plate 322 screens the material according to the new gap size. With such a setting, a variety of material sizes can be accommodated. By adjusting the gap size between the baffle plate 322 and the conveyor belt 311, the screening needs of materials of different sizes can be met. For products of different specifications, there is no need to replace the entire screening assembly 32, just simply slide the baffle plate 322 for adjustment, which greatly improves the versatility and flexibility of the equipment.

[0064] Among them, the pallet assembly 3111 is composed of one or more pallets in a row, and multiple rows of pallet assemblies 3111 are evenly spaced and distributed on the working surface of the conveyor belt 311, so as to support the material on the conveyor belt 311 for transportation and lifting through the pallet assemblies 3111.

[0065] See also Figure 6 In some embodiments, a first strip-shaped hole 3213 is transversely formed on the first adjustment plate 3212 , and an end of the material blocking plate 322 is movably disposed in the first strip-shaped hole 3213 .

[0066] The first strip hole 3213 is extended in a direction roughly perpendicular to the inclined plane of the conveyor belt 311, and the end of the baffle plate 322 is movably embedded in the first strip hole 3213, and a spring is arranged between the baffle plate 322 and the end of the first strip hole 3213 close to the conveyor belt 311, and a threaded hole is opened at the end of the first strip hole 3213 away from the conveyor belt 311, and an adjusting screw is arranged in the threaded hole, and the end of the adjusting screw is abutted against the baffle plate 322, so that the baffle plate 322 can slide in the first strip hole 3213 by rotating the adjusting screw, so as to be adjusted. In this way, the baffle plate 322 can be ejected outward by rotating the adjusting screw, so that the baffle plate 322 can slide in the first strip hole 3213 for adjustment. The structure is simple, the assembly and production costs are low, and the adjustment is convenient.

[0067] Furthermore, a rod is provided at one end of the first strip hole 3213 close to the conveyor belt 311, and a blind hole is correspondingly opened at the end of the baffle plate 322, the rod is inserted into the blind hole, a spring is sleeved on the rod and the spring is accommodated in the blind hole, so that a force is applied to the baffle plate 322 in a direction away from the conveyor belt 311 through the spring, so that the baffle plate 322 can be slidably adjusted along the rod, which can effectively prevent the end face of the baffle plate 322 from detaching from the first strip hole 3213, so as to improve the stability and reliability of the structure.

[0068] See also Figure 7 In some embodiments, arc-shaped holes 3121 are provided on both sides of the loading rack 312, and clamping shafts 3112 are provided on both sides of the bottom of the conveyor belt 311, and the clamping shafts 3112 are movably provided in the arc-shaped holes 3121; connecting screws 3114, second nuts 3115 and sleeves 3116 are provided on both sides of the top of the conveyor belt 311, one end of the connecting screw 3114 is hinged to the loading rack 312, one end of the sleeve 3116 is hinged to the upper part of the conveyor belt 311, and the other end of the sleeve 3116 is sleeved on the other end of the connecting screw 3114, and the second nut 3115 is threadedly connected to the connecting screw 3114, and the second nut 3115 abuts against the other end of the sleeve 3116.

[0069] Among them, a first nut 3113 is also provided on the clamping shaft 3112, the clamping shaft 3112 is arranged on both sides of the bottom of the conveyor belt 311, and an arc hole 3121 is opened on the side of the loading rack 312, the arc hole 3121 is roughly bent and extended around the central axis of the clamping rhythm to form an arc, the clamping shaft 3112 can be slidably inserted in the arc hole 3121, and the first nut 3113 is sleeved on the end of the clamping shaft 3112, so that the clamping shaft 3112 on the conveyor belt 311 can slide in the arc hole 3121 by loosening the first nut 3113, and at the same time, the top of the conveyor belt 311 can rotate around the central axis of the clamping shaft 3112, so as to adjust the inclination angle of the conveyor belt 311, and the adjustment is simple and fast, and it is easy to use. Furthermore, after the inclination angle of the conveyor belt 311 is adjusted, the first nut 3113 can be re-sleeved on the clamping shaft 3112. At this time, the clamping shaft 3112 is fixed on the arc hole 3121 and no longer slides, so that the inclination angle of the conveyor belt 311 is fixed.

[0070] By loosening the second nut 3115, the connecting screw 3114 and the sleeve 3116 can be movably fitted into each other to adjust the length of the overall rod formed by the connecting screw 3114 and the sleeve 3116, thereby enabling the conveyor belt 311 to rotate in the arc hole 3121 to adjust the inclination angle of the conveyor belt 311, and the conveyor belt 311 is supported by being arranged on the top of the conveyor belt 311.

[0071] In this embodiment, the bottom of the conveyor belt 311 is slidably connected in the arc hole 3121 through the clamping shaft 3112, and the top of the conveyor belt 311 is rotationally connected to the loading rack 312 through the connecting screw 3114, so that the inclination angle of the conveyor belt 311 on the loading rack 312 can be adjusted.

[0072] Please also read Figure 8 and Fig. 9 , Figure 8 It is a schematic assembly diagram of a lifting device 30 and a material guiding device of an automatic weight sorting machine 100 provided by another embodiment of the present invention; Fig. 9 yes Figure 8A is an enlarged schematic diagram. In some embodiments, the screening assembly 32 includes an impeller assembly 321, and the impeller assembly 321 includes a blade 3213, a rotating shaft 3214, a driving unit 3215, and a second adjustment plate 326; a plurality of blades 3213 are arranged around the rotating shaft 3214; the rotating shaft 3214 is rotatably arranged in the transverse direction on the upper part of the conveyor belt 311, and the output shaft of the driving unit 3215 is drivingly connected to the rotating shaft 3214, so that the rotating shaft 3214 is driven by the driving unit 3215 to rotate, and the blade 3213 close to the conveyor belt 311 is arranged at an interval with the conveyor belt 311; the second adjustment plate 326 is movably arranged on both sides of the conveyor belt 311, and the rotating shaft 3214 is arranged on the second adjustment plate 326.

[0073] The conveyor belt 311 is tiltedly arranged on the loading rack 312, and a plurality of rows of support plate assemblies 3111 are arranged at intervals on the belt surface of the conveyor belt 311. The screening assembly 32 includes a driving part 3215, a rotating shaft 3214 and a plurality of blades 3213. The driving part 3215 can adopt a servo motor. The plurality of blades 3213 are arranged around the rotating shaft 3214, and the blades 3213 extend from one side of the conveyor belt 311 to the other side of the conveyor belt 311. The rotating shaft 3214 is rotatably arranged in the transverse direction of the conveyor belt 311. 11, the output shaft of the driving part 3215 is connected with the rotating shaft 3214 to rotate through the driving part 3215, and the blade 3213 that runs to the side close to the conveyor belt 311 is spaced apart from the blade 3213 that runs to the side close to the screening material assembly 32. In this way, by providing a gap space between one of the blades 3213 and the adjacent conveyor belt 311, the blade 3213 can be prevented from rotating and interfering with the support plate assembly 3111 on the conveyor belt 311.

[0074] It can be seen that in the present embodiment, a screening assembly 32 is provided on the upper portion of the conveyor belt 311, so as to drive the rotating shaft 3214 to rotate and drive the plurality of blades 3213 to rotate through the driving portion 3215, so that when a plurality of materials are stacked together and conveyed upward on the same pallet assembly 3111, due to the large sum of the external volumes of the plurality of materials, a larger portion of the materials will generally be exposed beyond the edge of the pallet assembly 3111. In this way, the plurality of materials stacked together on the pallet assembly 3111 can be knocked off by the rotating blades 3213, thereby ensuring as much as possible that the weighing plate 211 contains only single materials, avoiding the plurality of materials stacked together from being fed together for weighing and sorting, thereby affecting the practicability and accuracy of the feeder 200, and thereby improving the accuracy of weighing and sorting.

[0075] In addition, the second adjustment plate 326 is movably arranged on both sides of the conveyor belt 311, and the rotating shaft 3214 is installed on the second adjustment plate 326. The second adjustment plate 326 can move horizontally on both sides of the conveyor belt 311, thereby driving the rotating shaft 3214 and the blade 3213 installed on the second adjustment plate 326 to move synchronously. At this time, when the adjustment plate moves toward the conveyor belt 311, the blade 3213 and the rotating shaft 3214 move synchronously toward the conveyor belt 311, and the gap between the blade 3213 and the supporting plate assembly 3111 on the conveyor belt 311 becomes smaller, which can be used to screen materials with smaller volumes; when the adjustment plate moves away from the conveyor belt 311, the blade 3213 and the rotating shaft 3214 move synchronously away from the conveyor belt 311, and the gap between the blade 3213 and the supporting plate assembly 3111 on the conveyor belt 311 becomes larger, which can be used to screen materials with larger volumes.

[0076] When the material is placed on the pallet assembly 3111 and lifted and transported upward, the larger the material's external volume is, the more the material will be exposed from the edge of the pallet assembly 3111. When multiple materials are stacked on the same pallet assembly 3111, the exposed portion usually exceeds the exposed portion of a normal single material. The material can be seafood or other materials, and this embodiment does not specifically limit it. In this way, by movably setting the second adjustment plate 326 on both sides of the conveyor belt 311, the size of the gap between the impeller and the pallet assembly 3111 can be adaptively adjusted according to the external volume of the material, so as to improve the applicability and reliability of the lifting device 30, and can be used for loading a variety of different materials, with a wide range of applications and easy use.

[0077] In some embodiments, a second strip-shaped hole 3261 is transversely opened on the second adjustment plate 326 , and the second adjustment plate 326 is movably connected to the conveyor belt 311 via the second strip-shaped hole 3261 .

[0078] The second bar hole 3261 can be passed through by screws or bolts, and then fixed to the side of the conveyor belt 311. At this time, the second adjustment plate 326 can be fixed on the conveyor belt 311, so that the rotating shaft 3214 connected to the second adjustment plate 326 is fixed on the conveyor belt 311. When the gap between the impeller and the support plate assembly 3111 is to be adjusted, the screws or bolts can be loosened, and then the second adjustment plate 326 can be moved to change the position of the second adjustment plate 326 on the conveyor belt 311. At this time, the positions of the rotating shaft 3214 and the impeller will be moved and changed synchronously, so that the gap between the impeller and the support plate assembly 3111 can be adjusted.

[0079] In some embodiments, the material receiving assembly 327 is disposed on the upper part of the conveyor belt 311, and the material receiving assembly 327 is located below the screening assembly 32, so as to receive and guide the material knocked down by the screening assembly 32 through the material receiving assembly 327. The material receiving assembly 327 also includes a material guiding channel 3271, which is obliquely extended from one side of the conveyor belt 311 to the other side of the conveyor belt 311.

[0080] Among them, the material guide channel 3271 is set at an angle, so that after receiving the knocked-down materials, the materials on the material guide channel 3271 can slide downward on the inclined material guide channel 3271 by their own gravity and thus leave the material guide channel 3271, without causing the knocked-down materials to accumulate on the material guide channel 3271.

[0081] In some other embodiments, the material receiving assembly 327 includes a material guide conveyor belt 3272 to receive and transport the material knocked down by the screening assembly 32 through the material guide conveyor belt 3272. The material on the material guide conveyor belt 3272 can move synchronously with the material guide conveyor belt 3272 by its own gravity, and the knocked down material will not be accumulated on the material guide conveyor belt 3272.

It can be understood that the automatic weight sorting machine 100 provided in the embodiment of the present invention also includes other structures for realizing the automatic weight sorting machine 100, including but not limited to material cleaning mechanisms, material boxes, etc.
