Description

Technical Field

[0001] This invention relates to the field of automatic sorting machine technology, and in particular to an automatic sorting machine and its receiving and temporary storage device. Background Technology

[0002] In the production of some materials (such as abalone), products of different weights are divided into different grades. For example, abalone can be divided into different grades such as Grade A and Grade B based on weight, which facilitates subsequent packaging and sales. The prices of abalone of different grades will also differ, thus achieving product differentiation and meeting the needs of different consumers. In this case, an automatic sorting machine can be used to sort the materials by weight for packaging and sale.

[0003] First, the various materials are sequentially fed to the weighing station by the feeding machine for weighing and sorting. Then, the sorted materials are poured into the material bin through the weighing pan assembly. Due to the limited capacity of the material bin, when the bin is full, workers need to remove it and store and transport the collected materials. During this time, since the sorting machine is constantly working, the material on the weighing pan assembly will be poured directly onto the ground after sorting, which is very inconvenient. If the sorting machine is temporarily turned off and then turned on again when the material bin is returned or replaced with an empty bin, the sorting machine will be turned on and off repeatedly when emptying the material from the bin, resulting in a decrease in sorting efficiency. Summary of the Invention

[0004] The present invention aims to provide an automatic sorting machine and its receiving and temporary storage device, and at least solves one of the technical problems existing in the prior art.

[0005] The technical solutions adopted by the embodiments of the present invention to solve their technical problems are as follows: A material receiving and temporary storage device is provided for use in an automatic sorting machine, comprising: The material receiving channel is open at both its upper and lower ends; A support component is movably disposed at the lower opening of the receiving channel to open or close the lower opening of the receiving channel. A drive assembly is retractably disposed between the receiving channel and the supporting assembly. The drive assembly can extend and retract to drive the supporting assembly to move and close the opening at the lower end of the receiving channel.

[0006] In some embodiments, a limiting component is further included, which is disposed on the lower side wall of the receiving channel. The limiting component abuts against the supporting component to keep the supporting component in a closed state, and the limiting component can elastically retract to allow the supporting component to move and open the opening at the lower end of the receiving channel.

[0007] In some embodiments, the support assembly includes a support plate and a rotating shaft. One end of the support plate is rotatably connected to the lower end of the receiving channel via the rotating shaft, so that the support plate is rotated by the drive assembly to close the opening at the lower end of the receiving channel.

[0008] In some embodiments, a positioning structure is provided between the supporting component and the lower end of the receiving channel to position the supporting plate when it is rotated to the closed state. The positioning structure includes a positioning groove and a connector. Positioning grooves are provided on both sides of the lower end of the receiving channel, and connectors are provided on both sides of the supporting plate. Two connectors are provided in correspondence with two positioning grooves so that when the supporting plate rotates, it is positioned by engaging the connectors into the positioning grooves.

[0009] In some embodiments, the limiting component includes a limiting member that is retractably disposed on both sides of the lower end of the receiving channel, such that when the lower end opening of the receiving channel is closed, the limiting member abuts against the connecting member, thereby restricting the connecting member within the positioning groove.

[0010] In some embodiments, the limiting member includes a mounting base and a first abutting portion; The mounting base is disposed on both sides of the lower end of the receiving channel, and the mounting base is hollowed out to form a moving space; The first abutting part is movably housed within the moving space; When the lower opening of the receiving channel is closed, the connector abuts against the first abutting part.

[0011] In some embodiments, the limiting member further includes an elastic member and a pushing part, and the side of the mounting base has a movable opening; The pushing part is connected to the first abutting part, and the pushing part is disposed within the moving port; One end of the elastic element abuts against the inner wall of the moving space, and the other end abuts against the first abutting part.

[0012] In some embodiments, the drive assembly includes a telescopic rod and a drive member, the drive member being driven to the telescopic rod, and the drive member being used to drive the telescopic rod to move in order to push the support plate to close the opening at the lower end of the receiving channel; The bottom of the support plate is provided with a guide abutment seat, which is correspondingly provided with the end of the telescopic rod. The telescopic rod and the guide abutment seat abut against each other to drive the support plate to rotate, thereby closing the opening at the lower end of the receiving channel.

[0013] In some embodiments, the driving member is an electromagnetic actuator, the telescopic rod is telescopically disposed within the driving member, and both ends of the telescopic rod are exposed. A spring is disposed between the end of the telescopic rod away from the support assembly and the driving member, so that when the electromagnetic actuator is de-energized, the spring drives the telescopic rod to move in a direction away from the support assembly.

[0014] On the other hand, the present invention also provides an automatic sorting machine, comprising: frame; Multiple weighing pan assemblies are mounted on the frame; The material receiving and storage device described in any of the above technical solutions is located below the weighing pan assembly, so that the weighing pan assembly pours out the material and pours it into the material box on the frame via the material receiving and storage device.

[0015] Compared with the prior art, in the automatic sorting machine and its receiving temporary storage device provided in this embodiment of the invention, the supporting component is movably disposed at the lower end of the receiving channel to close the opening at the lower end of the receiving channel. When material passes through the receiving channel, it can enter the receiving channel through the opening at the top. At this time, the supporting component closes the opening at the lower end of the receiving channel. The limiting component then abuts against the supporting component, restricting its movement within the receiving channel. This prevents material from falling into the receiving channel. With this design, when workers need to remove or replace a full material bin, the material being sorted can be temporarily collected through the cooperation of the receiving channel and the supporting component, preventing material from falling to the ground. Workers do not need to shut down the sorting machine when collecting a full material bin. The sorting machine can perform continuous sorting work with high efficiency and ease of use.

[0020] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention.

[0021] The following is combined with Figures 1 to 5The automatic sorting machine 200 and its receiving temporary storage device 100 provided in this application will be described in detail through specific embodiments.

[0022] It should be noted that the automatic sorting machine 200 can sort and weigh materials (such as seafood like abalone, or fruits).

[0023] Please refer to the following: Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the automatic sorting machine provided by the present invention; Figure 2 This is a schematic diagram of the material receiving temporary storage device provided by the present invention. One embodiment of the material receiving temporary storage device 100 provided by the present invention is applied to an automatic sorting machine 200. The material receiving temporary storage device 100 includes a receiving channel 10, a supporting component 20, and a limiting component 70. Both the upper and lower ends of the receiving channel 10 are open; the supporting component 20 is movably disposed at the lower opening of the receiving channel 10 to close the lower opening of the receiving channel 10; the limiting component 70 is retractably disposed on both sides of the lower end of the receiving channel. The limiting component 70 is telescopically disposed on both sides of the lower end of the receiving channel. The limiting component 70 and the supporting component 20 abut against each other so that the supporting component 20 is located at the opening at the lower end of the receiving channel 10. The limiting component 70 can retract so that the supporting component 20 can move on the receiving channel 10 to open the lower opening of the receiving channel 10. The driving component 30 is telescopically disposed between the receiving channel 10 and the supporting component 20. The driving component 30 can extend and retract to drive the supporting component 20 to move within the receiving channel 10.

[0024] Regarding the aforementioned receiving channel 10, it is open at both the upper and lower ends. After the automatic sorting machine 200 sorts the material (e.g., abalone) by weight, the material on the automatic sorting machine 200 can be poured onto the material box 50. As the material falls into the material box 50, it first enters the receiving channel 10 through the opening at the upper end and exits through the opening at the lower end before falling onto the material box 50. Specifically, the receiving channel 10 is set in a roughly vertical or inclined direction, so that the receiving channel 10 is adapted to the trajectory of the material falling under its own weight.

[0025] In this embodiment, the supporting component 20 is movably disposed at the lower end of the receiving channel 10 to close the opening at the lower end of the receiving channel. When material passes through the receiving channel 10, it can enter the receiving channel 10 through the opening on the upper part of the receiving channel 10. At this time, the supporting component 20 closes the opening at the lower end of the receiving channel 10. At this time, the limiting component 70 abuts against the supporting component 20 to restrict the movement of the supporting component within the receiving channel 10. The supporting component 20 can prevent material from falling through the receiving channel 10. With this configuration, when the worker needs to remove or replace the full material box 50, the material can be temporarily collected through the receiving channel 10 and the supporting component 20, preventing the material from falling through the receiving channel 10. This avoids the need to shut down the sorting machine 200, which would reduce the sorting efficiency, and is convenient to use. As more material is collected on the supporting component 20, the pressure exerted on the supporting component 20 increases. At this time, the supporting component 20 exerts a force on the limiting component 70, causing the limiting component 70 to be compressed and retracted. The limiting component 70 gradually moves away from the supporting component 20, and the supporting component 20 is no longer subjected to the resisting force from the limiting component 70. At this time, the supporting component 20 can move on the receiving channel 10, so that the lower opening of the receiving channel 10 can be opened, and the material falls into the material box 50 placed below the receiving channel 10.

[0026] Regarding the aforementioned drive assembly 30, the drive assembly 30 is retractably disposed between the receiving channel 10 and the supporting assembly 20. The drive assembly 30 can extend and retract to move the supporting assembly 20 within the receiving channel 10, thereby enabling the supporting assembly 20 to close the lower opening of the receiving channel 10. With this arrangement, when the lower opening of the receiving channel 10 is open and the material box 50 below the receiving channel 10 is removed, the drive assembly 30 can drive the supporting assembly 20 to move, thereby causing the supporting assembly 20 to block the lower opening of the receiving channel 10.

[0027] Specifically, when the drive component 30 extends, it gradually approaches and abuts against the support component 20. Then, the drive component 30 can move the support component 20 within the receiving channel 10, thereby closing the opening at the lower end of the receiving channel 10. At this time, the support component 20 gradually approaches and abuts against the limiting component 70, so that when the support component 20 closes the lower opening of the receiving channel 10, the limiting component 70 can restrict the movement of the support component 20 within the receiving channel 10. With this configuration, when the support component 20 moves to close the lower opening of the receiving channel 10, the limiting component 70 can abut against the support component 20 to restrict its movement and prevent the lower opening of the receiving channel 10 from opening again.

[0028] In other examples, when material passes through receiving channel 10, it is blocked by support component 20 and accumulates on support component 20. Due to the gravity of the material, a force is exerted on support component 20. At this time, support component 20 will apply this force to drive component. After being subjected to the force from support component 20, drive component can be compressed, so that drive component gradually moves away from support component 20. Then support component 20 can move within receiving channel to open the lower opening of receiving channel 10, and material can fall through the lower opening of receiving channel 10.

[0029] Please refer to the following: Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the bottom structure of the material receiving and temporary storage device provided by the present invention; Figure 4 This is a side view of the material receiving temporary storage device provided by the present invention. In some embodiments, the support assembly 20 includes a support plate 21 and a rotating shaft 22; the rotating shaft 22 is disposed on one side of the lower end of the material receiving channel 10; one end of the support plate 21 is rotatably connected to the rotating shaft 22, and the other end is close to the other side of the material receiving channel 10; the drive assembly can extend and retract to drive the support plate 21 to rotate around the rotating shaft 22.

[0030] In this embodiment, the rotating shaft 22 is located at the lower end of the receiving channel 10, and the support plate 21 is rotatably connected to the rotating shaft 22. The support plate 21 can rotate around the rotating shaft 22, thereby changing the angle of the support plate 21 within the receiving channel 10. At this time, while the support plate 21 is rotating, the distance between the other end of the support plate 21 and the inner wall of the receiving channel 10 will change. For example, when the support plate 21 rotates around the pivot 22 until the angle with the horizontal direction gradually decreases, the distance between the support plate 21 and the inner wall of the receiving channel 10 will gradually decrease, thereby gradually closing the lower opening of the receiving channel 10. At this time, the support plate 21 can be used to receive materials, which is applicable to the scenario where the material box 50 below the receiving channel 10 is removed, preventing materials from falling directly to the ground after passing through the receiving channel 10. When the support plate 21 rotates around the pivot 22 until the angle with the horizontal direction gradually increases, the distance between the support plate 21 and the inner wall of the receiving channel 10 will gradually increase, thereby gradually opening the lower opening of the receiving channel 10. At this time, the materials on the support plate 21 can fall down through the opening, which is applicable to the scenario where a material box 50 is set below the receiving channel 10. With this setup, when there is no material box 50 below the receiving channel 10, the support plate 21 gradually rotates towards the inner wall of the receiving channel 10 to close the lower opening of the receiving channel, thereby preventing the material from falling directly onto the frame 60 of the sorting machine 200; then, when the material in the receiving channel 10 increases, the support plate 21 can rotate away from the inner wall of the receiving channel 10 due to the weight of the material, at which point the lower opening of the receiving channel 10 is opened, and the material can fall onto the material box 50.

[0031] In some other embodiments, the support plate 21 is horizontally slidable within the receiving channel 10. In this case, the support plate 21 can gradually move closer to or further away from the inner wall of the receiving channel 10 in the horizontal direction, thereby opening or closing the opening below the receiving channel 10. This also achieves the purpose of the invention. Therefore, it is understood that any simple change to the movement of the support plate 21 (e.g., changing the rotation of the support plate 21 within the inner wall to movement) without requiring any labor effort is within the scope of protection of this invention.

[0032] In some embodiments, a sleeve 23 is provided at one end of the support plate 21 near the rotating shaft 22, and the sleeve 23 is sleeved on the rotating shaft 22.

[0033] In this embodiment, a sleeve 23 is provided on the support plate 21. The sleeve 23 has a hollowed-out middle section, so that the sleeve 23 can be fitted onto the rotating shaft 22. Then the rotating shaft 22 is fixed to the lower end of the receiving channel 10, thereby allowing one end of the support plate 21 to be connected to the sleeve 23, and enabling the support plate 21 to rotate around the rotating shaft 22 to open or close the lower opening of the receiving channel 10.

[0034] In some embodiments, a positioning structure is provided between the lower end of the support assembly 20 and the receiving channel 23 to position the support plate 21 to the closed state by means of the positioning structure.

[0035] Specifically, the positioning structure includes positioning grooves 12 and connectors 212. Positioning grooves 12 are provided on both sides of the lower end of the receiving channel 10, and connectors 212 are provided on both sides of the other end of the support plate 21. The connectors 212 are movably housed in the positioning grooves 12 to accommodate the rotation of the support plate 21. The two connectors 212 are provided in a one-to-one correspondence with the two positioning grooves 12, so that when the support plate 21 rotates, the connectors 212 are engaged into the positioning grooves 12 to achieve positioning.

[0036] Positioning grooves 12, roughly inverted V-shaped, are provided on both sides of the lower end of the receiving channel 10. Connectors 212 on both sides of the other end of the support plate 21 can be accommodated within these positioning grooves 12. This arrangement provides the receiving channel 10 with sufficient accommodating space. Specifically, when the support plate 21 rotates around the pivot 22 to open or close the lower opening of the receiving channel 10, the connectors 212 of the support plate 21 can move in an arc within the positioning grooves 12. At this time, the positioning grooves 12 are roughly inverted V-shaped, adapting to the movement trajectory of the connectors 212.

[0037] Please refer to the following: Figure 4 , Figure 5 , Figure 5 yes Figure 4Enlarged schematic diagram at point A; In some embodiments, the limiting component 70 further includes a limiting member 74, which is retractably disposed on both sides of the lower end of the receiving channel 10, and the limiting member 74 is inclined downwards approximately along the horizontal plane; wherein, when the lower end opening of the receiving channel 10 is in the closed state, the connecting member 212 and the limiting member 74 abut against each other, thereby restricting the connecting member 212 within the positioning groove 12.

[0038] The limiting member 74 is fixed to both sides of the lower end of the receiving channel 10, and the limiting member 74 is telescopic. When the limiting member 74 is in the uncompressed state, part of the limiting member 74 is located on the side wall of the positioning groove 12 (either the inner or outer side). As the support plate 21 gradually approaches the inner wall of the receiving channel 21, the connecting member 212 can gradually approach the limiting member 74 and make contact with it. Furthermore, while the support plate 21 continues to rotate, the connecting member 212 can exert a force on the limiting member 74 to compress it, thereby allowing the support plate 21 to continue rotating to close the lower opening of the receiving channel 21. Furthermore, when the support plate 21 closes the lower opening of the receiving channel, the connector 212 is in the recessed part of the positioning groove 12. The connector 212 does not exert force on the limiting member 74. After the limiting member 74 undergoes elastic deformation, it stretches and returns to its original shape. At this time, the limiting member blocks the opening of the positioning groove 12, thereby causing the limiting member 74 to lock the connector 212 in the positioning groove 12, thus restricting the movement of the connector 212. With this setting, the limiting member 74 can lock the support plate 21, thereby restricting the support plate 21 from moving to open the lower opening of the receiving channel 10. In the absence of a material box 50 below the receiving channel 10, this prevents materials from falling directly onto the frame 60.

[0039] It should be noted that it is preferable for the limiting member 74 to be located on the outer side wall of the positioning groove 12, so as to facilitate the user to control the limiting member 74.

[0040] Furthermore, the limiting member 74 is inclined downwards in a roughly horizontal direction. When the support plate 21 rotates upwards to approach the inner wall of the receiving channel 10, the bottom of the limiting member 74 is set at an angle to the support plate 21, so that the support plate 21 can exert a force on the limiting member 74 to cause the limiting member 74 to retract.

[0041] In some embodiments, the limiting member 74 includes a mounting base 741 and a first abutting part 742; the mounting base 741 is disposed on both sides of the lower end of the receiving channel 10, and a movable space is formed in the mounting base 741; the first abutting part 742 is movably received in the movable space, and the upper surface of the end of the first abutting part 742 is inclined downward, and the lower surface of the end of the first abutting part 742 is inclined upward; wherein, when the lower end opening of the receiving channel 10 is closed, the connecting member 212 abuts against the first abutting part 742.

[0042] The mounting base 741 is located on both sides of the lower end of the receiving channel 10. A first abutment portion 742 is provided within the mounting base 741. The first abutment portion 742 can move within the mounting base 741, allowing it to be either exposed or contained within the mounting base 741. When the first abutment portion 742 is exposed within the mounting base 741, it is located on the wall of the positioning groove 12, thus blocking the opening of the positioning groove 12 and preventing the connector 212 from entering the positioning groove 12 or abutting against the connector 212 located within the positioning groove 12. When the first abutment portion 742 is located within the mounting base 741, it moves away from the positioning groove 12, opening the groove and allowing the connector 212 to enter the positioning groove 12 as the support plate 21 rotates.

[0043] During the process of closing the lower opening of the receiving channel 10 by the support plate 21, the support plate 21 drives the connector 212 to rotate upward. The connector 212 moves to the end of the first abutting part 742 and abuts against it. After the connector 212 applies a force to the first abutting part 742, the connector 212 can cause the first abutting part 742 to retract, thereby causing the first abutting part 742 to retract into the mounting base 741. At this time, the slot of the positioning groove 12 is opened, and the connector 212 can rotate synchronously with the support plate 21 to enter the positioning groove 12. After the support plate 21 is fixed in position, the connector 242 separates from the end of the first abutment 742. The first abutment 742 is no longer subjected to force from the connector 242 and expands towards the positioning groove 12, thereby moving the first abutment 742 to the side wall of the positioning groove 12. At this time, the connector 212 located in the arc-shaped groove can abut against the top of the first abutment 742, thereby restricting the downward movement of the connector 212. With this arrangement, the first abutment 742 is movably disposed on the lower end groove wall of the receiving channel 10. On the one hand, it can move towards the mounting base 741 to open the groove of the positioning groove 12 to facilitate the movement of the connector 212; on the other hand, it can move away from the mounting base 741 to close the groove of the positioning groove 12, preventing the connector 212 and the support plate 21 from rotating downward from the positioning groove 12 due to their own weight, thereby opening the lower end opening of the receiving channel 10.

[0044] In some embodiments, the limiting member 74 further includes an elastic member (not shown) and a pushing part 743. The side of the mounting base 741 is provided with a moving opening 7411. The pushing part 743 is connected to the first abutting part 742, and the pushing part 743 is disposed in the moving opening 7411. One end of the elastic member abuts against the mounting base 741, and the other end abuts against the first abutting part 742.

[0045] The elastic element can be a spring. The elastic element has a certain elasticity. When the elastic element is compressed, it can accumulate elastic potential energy, and when no external force compresses the elastic element, the elastic element can return to its original shape through elastic potential energy.

[0046] The elastic element is installed in the mounting base 741, and its two ends abut against the end of the first abutment portion 742 and the inner wall of the mounting base 741, respectively. During the process of closing the lower opening of the receiving channel 10 with the support plate 21, the support plate 21 drives the connector 212 to rotate upwards. The connector 212 moves to abut against the end of the first abutment portion 742. After the connector 212 applies force towards the first abutment portion 742, the connector 212 can cause the first abutment portion 742 to retract, thereby causing the first abutment portion 742 to retract into the mounting base 741. At this time, the opening of the positioning groove 12 is opened, and the elastic element is compressed. The connector 212 can rotate synchronously with the support plate 21 to enter the positioning groove 12. After the support plate 21 is positioned and fixed, the connector 242 separates from the end of the first abutment 742. The first abutment 742 is no longer subjected to force from the connector 242, and the elastic member undergoes elastic deformation to return to its original shape. This allows the first abutment 742, which abuts against the elastic member, to move to the side wall of the positioning groove 12. At this time, the connector 212, located in the arc-shaped groove, can abut against the top of the first abutment 742, thereby restricting the downward movement of the connector 212. With this arrangement, an elastic member is provided between the mounting base 741 and the first abutment 742, allowing the first abutment 742 to automatically adjust its position without requiring manual movement, thus improving work efficiency.

[0047] Furthermore, a movable opening 7411 is provided on the mounting base 741, specifically on the side of the mounting base 741, which facilitates user operation of the pushing part 743 located within the movable opening 7411. The movable opening 7411 is arranged laterally and its length is greater than the length of the pushing part 743, thereby allowing the pushing part 743 to slide within the movable opening 7411, thereby driving the first abutment part 742 to slide within the mounting base 741.

[0048] In some embodiments, the drive assembly 30 includes a telescopic rod 31 and a drive member 32, which are connected to each other. The drive member 32 is used to drive the telescopic rod 31 to move closer to or away from the support plate 21. The bottom of the support plate 21 is provided with a guide abutment seat 211, which is provided with the end of the telescopic rod 31. The guide abutment seat 211 and the telescopic rod 31 abut against each other to drive the support plate 21 to rotate around the pivot 22, thereby closing the lower opening of the receiving channel 10.

[0049] Preferably, the driving component 32 is an electromagnetic actuator. The specific structure and principle of the electromagnetic actuator driving the telescopic rod 31 to move closer to the supporting component 20 are existing technologies and will not be described in detail here. The telescopic rod 31 is telescopically disposed inside the driving component 32, and both ends of the telescopic rod 31 are exposed. A spring is disposed between the end of the telescopic rod 31 away from the supporting component 20 and the driving component 32, so that when the electromagnetic actuator is de-energized, the spring force drives the telescopic rod 31 to move in the direction away from the supporting component 20.

[0050] When the support plate 21 is located within the receiving channel 10 and the lower opening of the receiving channel 10 is closed, the connector 212 is positioned above and in contact with the first abutment portion 742, which restricts the connector 212 from rotating downwards. At this time, the drive member 32 can drive the telescopic rod 31 away from the guide abutment seat 211.

[0051] The driving component 32 is connected to the telescopic rod 31, and the driving component 32 can drive the telescopic rod 31 to move closer to or away from the support plate 21. When it is necessary to adjust the position of the support plate 21, the driving component 32 drives the telescopic rod 31 to move closer to the support plate 21, so that the telescopic rod 31 abuts against the guide abutment seat 211. Then, the telescopic rod 31 can drive the support plate 21 to rotate towards the inner wall of the receiving channel 10, thereby closing the lower opening of the receiving channel 10. After the support plate 21 is adjusted to the correct position, the driving component 32 can drive the telescopic rod 31 to move away from the support plate 21 until it separates from the guide abutment seat 211. With this configuration, the support plate 21 can be rotated, thereby facilitating the adjustment of the position of the support plate 21.

[0052] It should be noted that the guide abutment 211 is located at the bottom of the support plate 21 and is generally vertically arranged (or can be slightly inclined vertically), so that the guide abutment 211 can abut against the telescopic rod 31 which is generally horizontally arranged.

[0053] In one embodiment, the guide abutment 211 includes an abutment surface 2111 and a guide surface 2112; the abutment surface 2111 is disposed corresponding to the telescopic rod 31; the guide surface 2112 extends along the abutment surface 2111 toward the support plate 21.

[0054] The contact surface 2111 and the telescopic rod 31 are respectively provided. The contact surface 2111 is generally set vertically (or can be set slightly inclined vertically) so as to facilitate contact with the telescopic rod 31.

[0055] The guide surface 2112 is positioned along the abutment surface 2111 towards the support plate 21. When the support plate is rotated to close the lower opening of the receiving channel 10, the drive unit 32 drives the telescopic rod 31 to move towards the support plate 21. The telescopic rod 31 first contacts the guide surface 2112, applying force to it, causing the support plate 21 to gradually rotate towards the inner wall of the receiving channel 10. During this process, the telescopic rod 31 moves along the guide surface 2112 until it contacts the abutment surface 2111. This arrangement allows the guide surface 2112 to act as a transition guide, preventing the telescopic rod 31 from getting stuck during contact with the abutment surface 2111.

[0056] Please see Figure 1 On the other hand, the present invention also provides an automatic sorting machine 200, including the aforementioned receiving and temporary storage device 100, weighing pan assembly 40, and frame 60. At least one weighing pan assembly 40 is disposed on the frame 60, and the receiving and temporary storage device 100 is disposed below the weighing pan assembly 40, so that the weighing pan assembly 40 pours out the material and pours it into the material bin 50 via the receiving and temporary storage device 100.

[0057] After the weight of the material is detected, the weighing pan assembly 40 can send the detected material to the receiving channel 10. The material enters the receiving channel 10 through the opening on the receiving channel 10 and then falls onto the material bin 50. When the material bin 50 is full and needs to be removed, the drive assembly 30 can drive the support assembly 20 to move towards the inner wall of the receiving channel 10 to close the lower opening of the receiving channel 10. At this time, the limiting assembly 70 and the support assembly 20 abut against each other to restrict the movement of the support assembly 20 to open the lower opening of the receiving channel 10, so that the material can be temporarily stored in the space enclosed by the receiving channel 10 and the support assembly 20, preventing the material from falling directly onto the frame 60. Furthermore, once a certain amount of material has been collected in the receiving channel, there is a certain period of time to place the empty material box 50 on the frame 60. At this time, the supporting component 20 applies a force towards the limiting component 70, causing the limiting component 70 to retract. The limiting component 70 no longer restricts the movement of the supporting component 20, and the supporting component 20 moves, thereby opening the lower opening of the receiving channel 10. The material collected in the receiving channel 10 falls into the empty material box 50 on the frame 60. With this setting, it is not necessary to temporarily shut down the sorter 200. When the material box 50 is removed, the receiving channel 10 and the supporting component 20 work together to temporarily collect the material. The sorter 200 can still operate even when the material box 50 is not placed on the frame 60, thereby improving the working efficiency of the sorter 200.
