Description

Technical Field

[0001] This application relates to the field of ton bag recycling technology, and in particular to an automatic unpacking device. Background Technology

[0002] The automatic bag unpacking equipment's bag collection bin can recycle discarded ton bags after unloading. The bag collection bin enters the cabinet of the automatic bag unpacking equipment to recycle the ton bags and then leaves the feeding cabinet after recycling. Currently, when ton bags need to be recycled, a lifting mechanism located at the bottom of the bag collection bin drives the bag collection bin to rise, so that the bag collection bin seals against the feeding cabinet, preventing dust generated during the recycling process from escaping.

[0003] However, when the lifting mechanism drives the bag collection bin to rise, it needs to support the heavy bag collection box and resist the pressure exerted by the pressure plate that squeezes the bag, which affects the sealing effect between the bag collection box and the cabinet. Utility Model Content

[0004] This application provides an automatic unpacking device to solve the technical problem of existing automatic unpacking devices that, by setting a lifting mechanism at the bottom of the bag collection bin, require the lifting mechanism to bear the weight of the bag collection bin and resist the pressure exerted by the pressure plate that squeezes the ton bag, thereby affecting the sealing effect between the bag collection bin and the cabinet.

[0005] In a first aspect, this application provides an automatic unpacking device, including a cabinet with a recycling bin and a recycling port connected to the recycling bin; a bag collection box with a bag collection compartment and a bag collection opening connected to the bag collection compartment, the bag collection box being detachably housed in the recycling bin; a sealing mechanism including a first sealing part and a second sealing part connected to the first sealing part, the first sealing part being fixedly and sealingly connected to the cabinet at the edge of the recycling port, the second sealing part being movable relative to the first sealing part toward a side away from or closer to the first sealing part, such that the second sealing part is sealedly connected to or spaced apart from the bag collection box at the edge of the bag collection opening; or, the first sealing part is fixedly and sealingly connected to the bag collection box at the edge of the bag collection opening, the second sealing part being movable relative to the first sealing part toward a side away from or closer to the first sealing part, such that the second sealing part is sealedly connected to or spaced apart from the cabinet at the edge of the recycling port; the sealing mechanism is provided with a through hole, the through hole being used to penetrate the first sealing part and the second sealing part along the direction of relative movement of the first sealing part and the second sealing part, and for connecting the recycling port and the bag collection opening.

[0006] In this application, the sealing mechanism is located between the recycling port and the bag collection port. The first sealing part of the sealing mechanism is sealed to the edge of the bag collection port or the recycling port. When the bag collection box is accommodated in the recycling bin, the second sealing part of the sealing mechanism moves towards the recycling port or the bag collection port, so that the second sealing part is sealed to the edge of the recycling port or the bag collection port. Thus, the sealing mechanism can be sealed to the edges of the bag collection port and the recycling port respectively, providing a sealed environment for the recycling of ton bags. Since the sealing mechanism is located between the recycling port and the bag collection port, the second sealing part only needs to move its own weight when moving, without moving the bag collection box. Furthermore, after the sealing mechanism is sealed to the edges of the bag collection port and the recycling port respectively, it does not need to resist the squeezing force of the ton bag, resulting in a better sealing effect and higher stability of the automatic unpacking equipment.

[0007] In one possible implementation, the first sealing part and the second sealing part are integrally formed and configured as a telescopic structure; alternatively, the first sealing part and the second sealing part are independently arranged and slidably connected to form a telescopic structure; alternatively, the first sealing part and the second sealing part are independently arranged, and one of the first sealing part and the second sealing part is configured as a telescopic structure; alternatively, the first sealing part and the second sealing part are independently arranged, and the sealing mechanism further includes a telescopic structure connected between the first sealing part and the second sealing part. The telescopic structure can adapt to the relative movement between the second sealing part and the first sealing part, thereby achieving a dynamic seal between the bag opening and the recycling port, preventing dust leakage, and avoiding dust pollution of the surrounding environment and harm to the health of workers.

[0008] In one possible implementation, the second sealing part is configured as a rigid structure, and a sealing ring is provided on the side of the second sealing part facing away from the first sealing part. The rigid structure of the second sealing part ensures structural stability during reciprocating movement. The sealing ring improves the sealing effect between the rigid second sealing part and the bag opening or recycling port.

[0009] In one possible implementation, the sealing mechanism includes a drive member, which is fixedly installed in the cabinet, or the drive member is fixedly installed in the bag collection box, or the drive member is fixedly installed in the first sealing part, the first sealing part being configured as a rigid structure; the output end of the drive member is connected to the second sealing part, and the drive member is used to drive the second sealing part to move relative to the first sealing part toward a side away from or toward the first sealing part.

[0010] The cabinet, bag collection box, and the first sealing part, configured as a rigid structure, all possess high rigidity and strength, providing a stable support platform for the drive component and ensuring its stable operation. The drive component applies a driving force to the second sealing part, either moving away from or towards the first sealing part, ensuring the second sealing part seals against the edge of the bag collection opening or recycling port. Simultaneously, the drive component provides support force to the second sealing part, ensuring a tight fit between the second sealing part and the edge of the bag collection opening or recycling port, preventing displacement or loss of the sealing position, and improving the sealing effect.

[0011] In one possible implementation, the second sealing part has at least one symmetrical plane parallel to the height direction of the automatic unpacking device. The number of driving members is multiple, and the multiple driving members are arranged at intervals along the four edges of the second sealing part. At least two of the multiple driving members are symmetrically arranged relative to the corresponding symmetrical planes, so that the driving force acting on the second sealing part is evenly distributed, ensuring that each point on the four edges of the second sealing part is tightly fitted with the edge of the bag opening or recycling opening, thus ensuring the sealing effect of the second sealing part.

[0012] In one possible implementation, the bag collection bin is used to hold ton bags. The automatic unpacking device includes a sensor for detecting the cumulative height of the ton bags within the collection bin. The sensor is electrically connected to a drive unit. When the cumulative height of the ton bags within the collection bin reaches a preset position, the drive unit drives the second sealing part to separate from the bag collection opening or the recycling port. The sensor can detect the state of the ton bags within the collection bin, preventing excessive accumulation or overflow of the ton bags. This ensures that the sealing between the second sealing part and the bag collection opening or recycling port can be released after the collection bin reaches full capacity, thereby enabling the transfer of the collection bin.

[0013] In one possible implementation, the automatic unpacking device includes a guide component disposed on the cabinet or the bag collection box. When the bag collection box is housed in the recycling bin, the guide component abuts against the inner wall of the recycling bin and the outer wall of the bag collection box. The guide component guides the bag collection box to move into the recycling bin along a preset trajectory. As the bag collection box moves relative to the recycling bin, the guide component cooperates with the inner wall of the recycling bin or the outer wall of the bag collection box to correct and limit the movement path of the bag collection box, preventing problems such as offset, jamming, or misalignment. This ensures that the bag collection box moves smoothly and accurately into the recycling bin along the preset trajectory, thereby ensuring reliable docking between the bag collection opening of the bag collection box and the recycling opening of the recycling bin, ensuring that the ton bag can smoothly fall from the recycling opening into the bag collection bin, completing the collection of the ton bag.

[0014] In one possible implementation, there are two guide members, with the collection box located between them. The two guide members are used to roll against the outer wall of the collection box or the inner wall of the recycling bin. As the collection box enters or leaves the recycling bin, the two guide members roll against the outer wall of the collection box or the inner wall of the recycling bin. Rolling friction occurs between the guide members and the outer wall of the collection box or the inner wall of the recycling bin. This rolling friction has a lower coefficient of friction, resulting in less resistance to the collection box during movement and smoother, more stable movement.

[0015] In one possible implementation, the distance between the two guide members gradually increases in the direction of the bag collection box's movement away from the preset trajectory, so that the position of the bag collection box is gradually adjusted by the guide members during the process of the bag collection box entering the recycling bin, preventing the bag collection box from shifting.

[0016] In one possible implementation, the guide includes a mounting base and multiple rollers. The mounting base is fixedly mounted on the cabinet or the bag collection box. The multiple rollers are spaced apart along a direction parallel to the preset trajectory and rotatably mounted on the mounting base. The multiple rollers are used to roll against the outer wall of the bag collection box or the inner wall of the recycling bin. The multiple rollers can form a continuous guide surface, ensuring that the bag collection box remains in rolling contact with the rollers throughout its entry into the recycling bin, thereby reducing the resistance encountered by the bag collection box during movement.

[0038] This application provides an automatic bag unpacking device 10, which integrates functions such as unpacking, feeding, and bag collection. It can be used for automated unpacking, feeding, and collection of ton bags, reducing manual intervention and achieving fully automated operation, thereby improving overall work efficiency. (See reference) Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, Figure 1 This is a schematic diagram of the structure of the automatic unpacking device 10 provided in this embodiment, where the recycling bin 110 does not contain the bag collection box 200. Figure 2 for Figure 1 A schematic diagram of the automatic unpacking device 10 in the unsealed state, showing the contents of the recycling bin 110, the collection bag box 200, and the sealing mechanism 300. Figure 3 for Figure 2 A schematic diagram of the sealing mechanism 300 of the automatic unpacking device 10 in the sealed state. Figure 4 for Figure 2 A schematic diagram of the collection box of the automatic unpacking device 10. The automatic unpacking device 10 includes a cabinet 100, a collection box 200, and a sealing mechanism 300. The cabinet 100 is provided with a recycling bin 110 and a recycling port 120 connected to the recycling bin 110. The recycling bin 110 is used to accommodate the collection box 200.

[0039] The bag collection box 200 is equipped with a bag collection compartment 210 and a bag collection opening 220 connected to the bag collection compartment 210. The bag collection box 200 can be detachably housed in the recycling compartment 110, facilitating bag removal, maintenance, and cleaning operations. After the ton bags are unloaded by the automatic unpacking device 10, the bag collection box 200 is placed in the recycling compartment 110. The ton bags fall from the recycling opening 120 and then enter the bag collection compartment 210 through the bag collection opening 220. When the bag collection compartment 210 is full, the bag collection box 200 is removed from the recycling compartment 110. Operators transfer the ton bags out of the bag collection compartment 210 and then move the bag collection box 200 back into the recycling compartment 110. The bag collection box 200 can recycle empty ton bags, helping to reduce packaging costs and improve resource utilization.

[0040] It should be noted that the ton bag in this application is a large-capacity, high-load-bearing freight bag used for packaging and transportation. It has a high load-bearing capacity and is usually used for handling solid materials such as granules, powders or lumps.

[0041] Ton bags are used to load materials, including but not limited to battery materials, food materials, pharmaceutical materials, fertilizer materials, or building materials. For example, in this application embodiment, ton bags are applied in the field of battery manufacturing to load materials such as positive electrode materials, negative electrode materials, conductive agents, and dispersants, or to load battery mixtures made from a mixture of multiple materials.

[0042] In this embodiment, when the collection bag box 200 is housed in the recycling bin 110, the collection bag box 200 is located on the opposite side of the recycling port 120 in the Z direction. There is a gap between the collection bag opening 220 and the recycling port 120 in the Z direction. The sealing mechanism 300 is located between the recycling port 120 and the collection bag opening 220, and the sealing mechanism 300 is respectively sealed to the edges of the collection bag opening 220 and the recycling port 120. This allows the recycling operation of the ton bag to be carried out in a closed environment, avoiding dust pollution of the surrounding environment and harm to the health of the workers.

[0043] See Figure 5 and Figure 6 , Figure 5 for Figure 2 A schematic diagram of the structure of the bag collection box 200 and the sealing mechanism 300 in the compressed state of the automatic unpacking device 10 in the first embodiment. Figure 6 for Figure 2 The diagram shows a second embodiment of the automatic unpacking device 10, including the bag collection box 200 and the sealing mechanism 300 in a stretched state. The sealing mechanism 300 includes a first sealing part 310 and a second sealing part 320 connected to the first sealing part 310. The first sealing part 310 is fixedly and sealed to the bag collection box 200 at the edge of the bag collection opening 220. The second sealing part 320 can move relative to the first sealing part 310 away from or closer to the first sealing part 310, so that the second sealing part 320 is sealed to the cabinet 100 at the edge of the recycling opening 120 or spaced apart. The sealing mechanism 300 is provided with a through hole 330, which is used to pass through the first sealing part 310 and the second sealing part 320 in the direction of relative movement of the first sealing part 310 and the second sealing part 320, and is used to connect the recycling opening 120 and the bag collection opening 220.

[0044] In some embodiments, the first sealing part 310 is fixedly and sealed to the cabinet 100 at the edge of the recycling port 120, and the second sealing part 320 can move relative to the first sealing part 310 toward the side away from or closer to the first sealing part 310, so that the second sealing part 320 is sealed to the bag collection box 200 at the edge of the bag collection port 220 or spaced apart.

[0045] In this application, the sealing mechanism 300 is located between the recovery port 120 and the bag collection port 220. The first sealing part 310 of the sealing mechanism 300 is sealed to the edge of the bag collection port 220 or the recovery port 120. When the bag collection box 200 is accommodated in the recovery bin 110, the second sealing part 320 of the sealing mechanism 300 can move toward the recovery port 120 or the bag collection port 220, so that the second sealing part 320 is sealed to the edge of the recovery port 120 or the bag collection port 220. Thus, the sealing mechanism 300 can be sealed to the edges of the bag collection port 220 and the recovery port 120 respectively, providing a sealed environment for the recovery of the ton bag. The ton bag enters the bag collection bin 210 in sequence through the recovery port 120, the through hole 330 and the bag collection port 220. Dust will not leak into the external environment through the connection between the sealing mechanism 300 and the bag collection port 220 and the recovery port 120, avoiding dust pollution of the surrounding environment and harm to the health of workers. The sealing mechanism 300 is located between the recycling port 120 and the bag collection port 220. When the second sealing part 320 moves, it only needs to move its own weight without moving the bag collection box 200. After the sealing mechanism 300 is sealed to the edges of the bag collection port 220 and the recycling port 120 respectively, it does not need to resist the squeezing force of the squeeze bag, resulting in a better sealing effect and higher stability of the automatic unpacking equipment 10.

[0046] In this embodiment, the first sealing part 310 can be directly connected to the second sealing part 320 or indirectly connected to the second sealing part 320. The first sealing part 310 is fixedly and sealed to the cabinet 100 at the edge of the recycling port 120 to prevent dust from escaping between the first sealing part 310 and the edge of the recycling port 120.

[0047] It should be noted that, in this embodiment, when the second sealing part 320 moves away from the first sealing part 310 and moves to the point where the second sealing part 320 abuts against the edge of the bag opening 220, the second sealing part 320 and the bag collection box 200 are sealed together at the edge of the bag opening 220. When the second sealing part 320 moves away from or closer to the first sealing part 310 and does not contact the bag opening 220, the second sealing part 320 and the bag opening 220 are spaced apart.

[0048] See Figure 5 and Figure 6 In some embodiments, the first sealing part 310 and the second sealing part 320 are independently arranged, and the sealing mechanism 300 further includes a telescopic structure 340, which is connected between the first sealing part 310 and the second sealing part 320. Figure 5 The diagram shows the state of the telescopic structure 340 under compression under external force. Figure 6The diagram illustrates the state of the telescopic structure 340 under tension. The first sealing portion 310 and the second sealing portion 320 are connected via the telescopic structure 340, which can be stretched or compressed to ensure that the second sealing portion 320 can move relative to the first sealing portion 310, either towards or away from it. The telescopic structure 340 allows the second sealing portion 320 to seal the bag opening 220 or the recycling port 120, preventing dust leakage and avoiding dust pollution of the surrounding environment and harm to the health of workers.

[0049] In this embodiment, the independent arrangement of the first sealing part 310 and the second sealing part 320 means that the first sealing part 310 and the second sealing part 320 are two independent structures manufactured and installed separately. The first sealing part 310 and the second sealing part 320 are not integrally formed, but exist separately as independent structures. The phrase "the first sealing part 310 and the second sealing part 320 are independently arranged" in the following text refers to the same situation.

[0050] In this embodiment, the telescopic structure 340 includes, but is not limited to, a sleeve-type telescopic structure, an accordion-type telescopic structure, or an adhesive-type telescopic structure.

[0051] In other embodiments, the first sealing portion 310 and the second sealing portion 320 are integrally formed and configured as a telescopic structure 340. The first sealing portion 310 and the second sealing portion 320 are themselves telescopic. The integral forming of the first sealing portion 310 and the second sealing portion 320 improves the sealing performance and structural strength between them. The telescopic structure 340 can accommodate relative movement between the second sealing portion 320 and the first sealing portion 310, thereby achieving a dynamic seal between the bag opening 220 and the recovery opening 120, preventing dust leakage and avoiding dust pollution of the surrounding environment and harm to the health of workers.

[0052] In some other embodiments, see [reference] Figure 7 As shown, Figure 7 for Figure 2 A schematic diagram of the third embodiment of the sealing mechanism 300 of the automatic unpacking device 10 is shown. The first sealing part 310 and the second sealing part 320 are independently arranged and slidably connected to form a telescopic structure 340. Exemplarily, both the first sealing part 310 and the second sealing part 320 are tubular structures. The first sealing part 310 is sleeved on the outside of the second sealing part 320, and the second sealing part 320 can move relative to the first sealing part 310 along its axial direction within the first sealing part 310. The first sealing part 310 and the second sealing part 320 together form a telescopic bushing structure. The fitting gap between the two tubular first sealing parts 310 and the second sealing part 320 is sealed by a sealing ring.

[0053] In some other embodiments, the first sealing portion 310 and the second sealing portion 320 are independently disposed, and one of the first sealing portion 310 and the second sealing portion 320 is configured as a telescopic structure 340. For example, as Figure 8 As shown, the first sealing part 310 is configured as a telescopic structure 340, and the second sealing part 320 is configured as a rigid structure. Of course, in some embodiments, the first sealing part 310 is configured as a rigid structure, and the second sealing part 320 is configured as a telescopic structure 340; or, both the first sealing part 310 and the second sealing part 320 are configured as telescopic structures 340. Therefore, configuring either the first sealing part 310 or the second sealing part 320 as a telescopic structure 340 allows either the first sealing part 310 or the second sealing part 320 to deform during the movement of the second sealing part 320 relative to the first sealing part 310, thereby maintaining a sealed connection between the second sealing part 320 and the bag opening 220 or the recycling port 120, preventing dust leakage, and avoiding dust pollution of the surrounding environment and harm to the health of workers.

[0054] See Figure 5 In some embodiments, the second sealing part 320 is configured as a rigid structure, and a sealing ring 321 is provided on the side of the second sealing part 320 facing away from the first sealing part 310. The rigid structure has high resistance to deformation and is not easily subjected to bending, stretching, or compression. When the sealing mechanism seals the bag opening 220 and the recycling opening 120, the second sealing part 320 moves relative to the first sealing part 310. The rigid configuration of the second sealing part 320 ensures that it maintains structural stability during reciprocating movement.

[0055] In this embodiment, the first sealing part 310 is sealed to the edge of the recycling port 120, and the sealing ring 321 is used to seal between the second sealing part 320 and the collection bag opening 220, thereby improving the sealing effect between the rigid second sealing part 320 and the collection bag opening 220.

[0056] In some other embodiments, the first sealing part 310 is sealed to the edge of the collection bag opening 220, and the sealing ring 321 is used to seal between the second sealing part 320 and the collection port 120. This improves the sealing effect between the rigid second sealing part 320 and the collection port 120.

[0057] In some embodiments, the sealing mechanism 300 includes a drive member 350. The drive member 350 is connected to the first sealing portion 310 or the second sealing portion 320 and is used to drive the first sealing portion 310 to move relative to the second sealing portion 320 toward a side away from or closer to the second sealing portion 320; or, to drive the second sealing portion 320 to move relative to the first sealing portion 310 toward a side away from or closer to the first sealing portion 310. In this embodiment, the drive member 350 is fixedly mounted to the first sealing portion 310. The first sealing portion 310 is configured as a rigid structure. Thus, the cabinet 100, the bag box 200, and the first sealing portion 310 configured as a rigid structure all have high rigidity and strength, providing a stable support platform for the drive member 350 and ensuring the stable operation of the drive member 350.

[0058] In this embodiment, refer to Figure 6 One end of the driving member 350 is fixedly connected to the first sealing part 310, and the output end of the driving member 350 is connected to the second sealing part 320. The driving member 350 is used to drive the second sealing part 320 to move relative to the first sealing part 310, either away from or closer to the first sealing part 310. Thus, the driving member 350 can apply a driving force to the second sealing part 320, moving it away from or closer to the first sealing part 310, so that the second sealing part 320 seals against the edge of the collection bag opening 220 or the recycling port 120. Simultaneously, the driving member 350 can also provide support force to the second sealing part 320, ensuring that the second sealing part 320 is tightly fitted against the edge of the collection bag opening 220 or the recycling port 120, preventing displacement or loss of the sealing position, and improving the sealing effect.

[0059] In some other embodiments, the drive unit 350 is fixedly mounted to the cabinet 100. Exemplarily, one end of the drive unit 350 is fixedly mounted to the inner wall of the recycling bin 110 of the cabinet 100, and the output end of the drive unit 350 is connected to the second sealing part 320.

[0060] In some other embodiments, the drive member 350 is fixedly mounted to the bag collection box 200. Exemplarily, the drive member 350 is fixedly mounted to the outer wall of the bag collection box 200, and the output end of the drive member 350 is connected to the second sealing part 320.

[0061] The driving component 350 may include, but is not limited to, a telescopic cylinder, an electric push rod, or a ball screw. In this embodiment, the driving component 350 includes a telescopic cylinder, which can continuously output force to continuously drive the second sealing part 320 upward to seal the bag opening 220 or the recovery port 120. The telescopic cylinder can also adjust the output force by adjusting the pressure of compressed air, so as to achieve adjustable sealing force.

[0062] See Figure 9 , Figure 9 for Figure 2 An enlarged view of the sealing mechanism 300 of the automatic unpacking device 10 is shown. In some embodiments, the second sealing portion 320 has at least one symmetry plane 301 parallel to the height direction of the automatic unpacking device 10. Multiple driving members 350 are arranged at intervals along the periphery of the second sealing portion 320. At least two of the driving members 350 are symmetrically arranged relative to each other on the corresponding symmetry planes 301, thereby ensuring a uniform distribution of the driving force acting on the second sealing portion 320. This guarantees that each point on the periphery of the second sealing portion 320 is tightly fitted to the edge of the bag opening 220 or the recycling port 120, ensuring the sealing effect of the second sealing portion 320.

[0063] In this embodiment, the height direction of the automatic unpacking device 10 is the Z direction, and the surfaces parallel to the height direction of the automatic unpacking device 10 are the XZ surface and the YZ surface. The symmetry surface 301 of the second sealing part 320 is coplanar with the XZ surface or coplanar with the YZ surface. Figure 9 The dashed lines in the middle show two of the symmetrical planes 301 of the second sealing part 320.

[0064] In this embodiment, "multiple" refers to a quantity of at least two, meaning that the number of drive members 350 is at least two. The term "multiple" in the following text has the same meaning. The output terminal of each drive member 350 is connected to the second sealing portion 320 and is used to apply driving force to the second sealing portion 320.

[0065] For example, in this embodiment, there are four driving members 350, two of which are symmetrical about a symmetry plane 301 that is coplanar with the XZ plane, and the other two driving members 350 are symmetrical about a symmetry plane 301 that is coplanar with the YZ plane.

[0066] Understandably, in this embodiment, each driving component 350 can drive the second sealing part 320 to rise and fall synchronously, so that the plane where the opening of the through hole 330 is located during the rising and falling of the second sealing part 320 is always parallel to the plane where the bag opening 220 or the recycling port 120 is located. This allows the second sealing part 320 to better fit the edge of the bag opening 220 or the recycling port 120, and avoids the second sealing part 320 from tilting upward, which would cause uneven circumferential force on the second sealing part 320.

[0067] In some other embodiments, the number of drive members 350 can be two. The two drive members 350 can be arranged opposite each other along the X direction, or symmetrically arranged along the YZ plane. Alternatively, the two drive members 350 can be arranged opposite each other along the Y direction, or symmetrically arranged along the XZ plane. Alternatively, the two drive members 350 can be arranged diagonally on the second sealing portion 320.

[0068] See Figure 5In some embodiments, the ton bags fall from the collection port 120 into the bag collection box 200, and the bag collection compartment 210 of the bag collection box 200 is used to hold the ton bags. The automatic unpacking device 10 includes a sensor 400, which can be disposed inside or outside the bag collection compartment 210, and is used to detect the cumulative height of the ton bags in the bag collection compartment 210. The sensor 400 converts the detected cumulative height of the ton bags into an electrical signal output. The sensor 400 is electrically connected to a drive unit 350, which is used to drive the second sealing part 320 to separate from the bag collection port 220 or from the collection port 120 when the cumulative height of the ton bags in the bag collection compartment 210 reaches a preset position.

[0069] In this embodiment, the preset position refers to a height threshold set within the bag collection bin 210, used to indicate the maximum permissible height that the ton bags stacked within the bag collection bin 210 can reach. When the cumulative height of the ton bags within the bag collection bin reaches this preset position, it indicates that the bag collection bin 210 is currently full or about to be full.

[0070] The sensor 400 can detect the status of the ton bags in the bag collection bin 210, preventing the ton bags in the bag collection bin 210 from piling up too high or even overflowing, and ensuring that the sealing contact between the second sealing part 320 and the bag collection port 220 or the recycling port 120 can be released after the bag collection bin 210 reaches the full load state, thereby realizing the transfer of the bag collection bin 210.

[0071] Understandably, when the first sealing part 310 of the sealing mechanism 300 is fixedly and sealed to the cabinet 100 at the edge of the collection port 120, the driving member 350 is used to drive the second sealing part 320 to separate from the collection port 220 when the accumulated height of the ton bags in the collection bin 210 reaches a preset position. Similarly, when the first sealing part 310 of the sealing mechanism 300 is fixedly and sealed to the collection box 200 at the edge of the collection port 220, the driving member 350 is used to drive the second sealing part 320 to separate from the collection port 120 when the accumulated height of the ton bags in the collection bin 210 reaches a preset position.

[0072] In this embodiment, the sensor 400 may include, but is not limited to, photoelectric, ultrasonic, or laser rangefinder sensors.

[0073] In some other embodiments, sensor 400 is electrically connected to the control system, and the control system is electrically connected to drive unit 350. Sensor 400 converts the detected cumulative height of the ton bag into an electrical signal output. The control system receives the electrical signal from sensor 400 and processes and judges the electrical signal. When the electrical signal fed back by sensor 400 indicates that the cumulative height of the ton bag has reached a preset position, the control system generates a control signal. Drive unit 350 drives the second sealing part 320 to displace relative to the bag collection port 220 or the recycling port 120 according to the received control signal, releasing the sealing state so that the subsequent bag collection box 200 can be moved out of the recycling bin 110.

[0074] In some other embodiments, the drive unit 350 has a built-in control system, and the sensor 400 is electrically connected to the control system within the drive unit 350. When the control system of the drive unit 350 receives the electrical signal output by the sensor 400 and determines that the accumulated height of the ton bag has reached a preset position, the control system of the drive unit 350 controls the drive unit 350 to drive the second sealing part 320 to move relative to the bag collection port 220 or the recycling port 120, thereby releasing the seal so that the subsequent bag collection box 200 can be moved out of the recycling bin 110.

[0075] See Figure 1 and Figure 10 , Figure 10 for Figure 2 The diagram shows the structure of the two guide members 500 and the bag collection box 200 of the automatic unpacking device 10. In some embodiments, the automatic unpacking device 10 includes guide members 500, which are disposed in the cabinet 100 (e.g., Figure 1 (as shown) or collection bag box 200 (e.g. Figure 10 As shown, when the collection bag 200 is contained in the recycling bin 110, the guide 500 abuts between the inner side wall 130 of the recycling bin 110 and the outer side wall 230 of the collection bag 200. The guide 500 is used to guide the collection bag 200 to move into the recycling bin 110 along a preset trajectory.

[0076] In this embodiment, the bag collection box 200 moves into the recycling bin 110 along the positive Y direction and moves out of the recycling bin 110 along the negative Y direction. As the bag collection box 200 moves relative to the recycling bin 110, the guide member 500 cooperates with the outer wall 230 of the bag collection box 200 to correct and limit the movement path of the bag collection box 200, preventing problems such as offset, jamming, or misalignment. This ensures that the bag collection box 200 moves smoothly and accurately into the recycling bin 110 along a preset trajectory, thereby ensuring reliable docking between the bag collection opening 220 of the bag collection box 200 and the recycling opening 120 of the recycling bin 110. This ensures that the ton bag can smoothly fall from the recycling opening 120 into the bag collection bin 210, completing the collection of the ton bag.

[0077] The specific structure of the guide component 500 can be adapted to meet the requirements. The guide component 500 includes, but is not limited to, one or more combinations of guide rail structure, slide groove structure, roller assembly, limiting protrusion or elastic guide block.

[0078] In some other embodiments, the length of the guide 500 along the Y direction is greater than the length of the bag collection box 200 along the Y direction, to ensure that the bag collection box 200 is always guided and limited by the guide 500 throughout the movement.

[0079] See Figure 10 In some embodiments, there are two guide members 500, which are arranged opposite each other along the X direction. The collection box 200 is located between the two guide members 500. The two guide members 500 can restrict the position of the collection box 200 in the X direction, ensuring that the collection box 200 can only enter the recycling bin 110 along a preset trajectory, thereby improving the stability and accuracy of the collection box 200 when moving along the preset trajectory. When the collection box 200 enters or leaves the recycling bin 110, the two guide members 500 roll against the outer wall 230 of the collection box 200 or the inner wall 130 of the recycling bin 110. Rolling friction occurs between the guide members 500 and the outer wall 230 of the collection box 200 or the inner wall 130 of the recycling bin 110. Rolling friction has a lower coefficient of friction, resulting in less resistance to the movement of the collection box 200 and smoother movement. The number of guide members 500 can also be one, three, or more.

[0080] Understandably, when the guide members 500 are installed on the outer wall 230 of the collection box 200, the two guide members 500 are used to roll against the inner wall 130 of the collection box 110 when the collection box 200 enters or leaves the collection bin 110.

[0081] See Figure 11 , Figure 11 for Figure 2The first-view structural diagram of the two guide members 500 of the automatic unpacking device 10 shows that in some embodiments, the distance between the two guide members 500 gradually increases towards the direction of movement of the bag collection box 200 in a direction parallel to a preset trajectory. In this embodiment, the preset trajectory of the bag collection box 200 is the trajectory along the Y direction relative to the recycling bin 110, and the direction parallel to the preset trajectory is the direction parallel to the Y direction. The direction of movement of the bag collection box 200 is the opposite direction of Y, and the direction of movement of the bag collection box 200 into the recycling bin 110 is the positive direction of Y. The distance L between the two guide members 500 in the X direction gradually increases towards the opposite direction of Y, so that the position of the bag collection box 200 is gradually adjusted by the guide members 500 during the process of the bag collection box 200 entering the recycling bin 110, preventing the bag collection box 200 from shifting.

[0082] See Figure 1 , Figure 2 See also Figure 10 and Figure 12 , Figure 12 for Figure 11 The diagram shows a second-view structural diagram of the two guide members 500 of the automatic unpacking device 10. In some embodiments, the guide member 500 includes a mounting base 510 and multiple rollers 520. The mounting base 510 is fixedly mounted on the cabinet 100 or the bag collection box 200. The multiple rollers 520 are spaced apart along a direction parallel to a preset trajectory and are rotatably mounted on the mounting base 510. The multiple rollers 520 are used to roll against the outer wall 230 of the bag collection box 200 or the inner wall 130 of the recycling bin. The mounting base 510 is fixed to the cabinet 100 or the bag collection box 200 to ensure the stability of the mounting base 510's position. The mounting base 510 serves as a support structure for fixing the multiple rollers 520. The multiple rollers 520 can form a continuous guide surface, ensuring that the bag collection box 200 rolls against the rollers 520 throughout its entry into the recycling bin 110, thereby reducing the resistance encountered by the bag collection box 200 during its movement.

[0083] In this embodiment, the mounting seats 510 of the two guide members 500 are respectively mounted on the two inner sidewalls 130 of the recycling bin 110 in the X direction. Exemplarily, the guide members 500 are mounted on the two inner sidewalls 130 of the recycling bin 110 by bolting, welding, or other means. Multiple rollers 520 are mounted on the side of the mounting seat 510 opposite to the inner sidewall 130 of the recycling bin 110. The multiple rollers 520 are spaced apart along the Y direction and are rotatable relative to the mounting seat 510. When the collection bag 200 moves into the recycling bin 110, the outer surface of the rollers 520 rolls against the outer sidewall 230 of the collection bag 200, guiding the collection bag 200 into the recycling bin 110 along a preset trajectory.

[0084] In other embodiments, the mounting bases 510 of the two guide members 500 are respectively mounted on the two outer side walls 230 of the bag collection box 200 in the X direction. Multiple rollers 520 are mounted on the side of the mounting base 510 away from the outer side walls 230 of the bag collection box 200. The multiple rollers 520 are spaced apart along the Y direction and are rotatable relative to the mounting base 510. When the bag collection box 200 moves into the recycling bin 110, the outer surface of the rollers 520 rolls against the inner side wall 130 of the recycling bin 110, guiding the bag collection box 200 into the recycling bin 110 along a preset trajectory.
