The ton bag unpacking method comprises the following steps: the ton bag is conveyed by the external conveying device 20 to the internal conveying device 30 in the unpacking room 10; the ton bag grabbing and transporting device 60 is located above the internal conveying device 30 and is lowered to grab the ton bag on the internal conveying device 30, and the ton bag grabbing and transporting device 60 drives the ton bag to rise; the ton bag grabbing and transporting device 60 drives the ton bag to move above the bag breaking device 40 and is lowered so that the bottom of the ton bag contacts the bag breaking device 40, the bag breaking device 40 pierces the ton bag, the material in the ton bag falls into the bag breaking device 40, and after the ton bag is discharged, the outer bag of the ton bag is driven by the ton bag grabbing and transporting device 60 to rise; the ton bag grabbing and transporting device 60 drives the outer bag of the ton bag to move above the outer bag collecting device 50 and releases the outer bag, the outer bag falls into the outer bag collecting device 50 and is conveyed out of the unpacking room 10 by the outer bag collecting device 50. Of course, the outer bag of the ton bag can also be called a waste bag.

[0092] In this embodiment, the ton bag is first conveyed by the external conveying device 20 into the unpacking room 10 and is transferred from the external conveying device 20 to the internal conveying device 30; since the internal conveying device 30 and the external conveying device 20 are arranged at intervals and the interval is not large, the ton bag can be automatically transferred from the external conveying device 20 to the internal conveying device 30 naturally without manual assistance, thereby improving the automation degree of ton bag unpacking. The ton bag grabbing and transporting device 60 above the internal conveying device 30 is lowered after the ton bag arrives, can grab the ton bag on the internal conveying device 30, is driven to rise after the ton bag is grabbed and moves above the bag breaking device 40; the ton bag grabbing and transporting device 60 drives the ton bag to descend so that the bottom of the ton bag contacts the bag breaking device 40, the bag breaking device 40 pierces the ton bag, and the material in the ton bag falls into the bag breaking device 40 along the opening at the bottom of the ton bag, the bottom of the ton bag is pierced, and the material in the ton bag can automatically fall into the bag breaking device 40 under its own gravity, again without manual assistance, thereby improving the automation degree of ton bag unpacking. After the material in the ton bag is completely discharged, the outer bag of the ton bag is driven by the ton bag grabbing and transporting device 60 to rise, then moves above the outer bag collecting device 50 and releases the outer bag, the outer bag falls into the outer bag collecting device 50 and is conveyed out of the unpacking room 10 by the outer bag collecting device 50.

[0135] As shown in FIG. 12 and FIG. 14, the ton bag grabbing and transporting device 60 comprises a hanger 68, which can take the form of a mounting seat 61 and is movably arranged on the top of the unpacking room 10, a bag hanging assembly 610 movably connected with the hanger 68, the hanger 68 can be a steel frame; the bag hanging assembly 610 is movably connected with the hanger 68, and has the hanging end 62 for hanging the bag of the ton bag; the bag unpacking assembly 620 is connected with the hanger 68 and is arranged above the hanging end 62 in a lifting manner, and when unpacking, the bag unpacking assembly 620 is lowered and acts on the ton bag to provide auxiliary force for the ton bag to leave the hanging end 62. The embodiment provides the ton bag with auxiliary force to leave the hanging end 62 by arranging the bag unpacking assembly 620, thereby accelerating the unpacking speed of the ton bag and avoiding the phenomenon of bag hanging that may occur when unpacking. Specifically, the bag hanging assembly 610 is connected with the hanger 68, and the bag hanging assembly 610 has the hanging end 62 for hanging the bag of the ton bag. When unpacking is needed, the bag unpacking assembly 620 can be lowered to press down on the ton bag, thereby providing auxiliary force for the ton bag to leave the hanging end 62, and accelerating the ton bag to leave the hanging end 62. When bag hanging or ton bag moving is needed, the bag unpacking assembly 620 is raised to avoid the ton bag and the hanging end 62. In this way, the unpacking efficiency is improved, the problem that the ton bag is difficult to separate is avoided, the bag hanging assembly 610 is not interfered, and compared with the traditional device, the bag hanging assembly 610 and the bag unpacking assembly 620 are combined to save equipment space, further simplify the equipment structure, and improve the automation degree of the ton bag grabbing and transporting device 60.

Since the jacking pushing plate 321 is below the direction ball bearing mounting seat 61, the jacking pushing plate 321 and the ton bag will move with the pushing of the side pushing baffle 331, and the ton bag may be too far forward. Here, the forward refers to the side away from the starting end of the conveying assembly 31; the ton bag enters the unpacking room and enters the unpacking stage; the jacking pushing plate 321 is retreated to the initial position by the front pushing assembly 34 and the rear pushing assembly 36; and the jacking assembly 32 is lowered to return to the initial position.

[0142] As shown in FIGS. 22-24, the external conveying device 20, the internal conveying device 30, the ton bag grabbing and transporting device 60, the dust removal device 80 and the first chamber 11 of the present embodiment can be combined into a front-end sealing device, wherein the first chamber 11 can also be referred to as a sealing box, and the ton bag grabbing and transporting device 60 can also be referred to as a ton bag lifting device.

[0143] The ton bag unpacking system can also be referred to as an unpacking device, which comprises an unpacking machine and the above-mentioned front-end sealing device. The unpacking machine comprises the second chamber 12, the third chamber 13, the bag breaking device 40 in the second chamber 12 and the outer bag collecting device 50 in the third chamber 13.

[0144] The front-end sealing device of the present embodiment is arranged on the upstream side of the unpacking machine, the sealing box is located on the upstream side of the unpacking machine, and the sealing box has a sealing cavity which is communicable with the unpacking machine. At least a part of the ton bag grabbing and transporting device 60 is movably arranged in the sealing cavity and used for moving the ton bag in the sealing box. The dust removal device 80 is in communication with the sealing cavity and used for dust removal in the sealing cavity.

[0145] As shown in FIGS. 22-24, the present embodiment provides a front-end sealing device upstream of the unpacking machine, and the main body of the front-end sealing device is a sealing box, which is connected to the ton bag grabbing and transporting device 60 and the dust removal device 80 outside the sealing box, to achieve the treatment of the ton bag before unpacking, thereby effectively controlling the dust during unpacking. Specifically, the sealing box is located on the upstream side of the unpacking machine, i.e., before the entrance of the unpacking machine, and has a sealed cavity. The design of the sealed cavity ensures that the ton bag can be subjected to necessary dust removal treatment in a closed environment before entering the unpacking machine, so that the transportation and treatment of the ton bag are not directly exposed to the factory environment, thereby reducing the spread of dust during unpacking. At least a part of the ton bag grabbing and transporting device 60 is movably arranged in the sealed cavity of the sealing box. The main function of the ton bag grabbing and transporting device 60 is to drive the ton bag to move inside the sealing box, which can achieve the transportation of the ton bag to the sealed cavity or further to the unpacking machine. The close cooperation between the ton bag grabbing and transporting device 60 and the sealing box ensures that the ton bag will not cause dust overflow in the sealed cavity during lifting. The dust removal device 80 is in communication with the sealed cavity of the sealing box, which can directly remove the dust inside the sealed cavity and provide a clean environment for the subsequent unpacking process. The above front-end sealing device not only effectively controls the dust pollution during unpacking and realizes dust-free operation during unpacking, but also protects the air quality in the factory and reduces the harm to the health of the operators.

[0146] In the present embodiment, the ton bag grabbing and transporting device 60 includes a driving mechanism and a grabbing mechanism. The driving mechanism is arranged above the sealing box and can move horizontally and vertically relative to the sealing box. Specifically, the driving mechanism and the sealing box are arranged one above the other, which not only saves space but also facilitates the control of the grabbing mechanism by the driving mechanism to ensure the stability during lifting of the ton bag. The driving mechanism is designed to have horizontal and vertical movement functions, which makes it possible to accurately position the ton bag. By adjusting the position of the driving mechanism, the grabbing mechanism can accurately reach above the ton bag, thereby achieving accurate grabbing and lifting of the ton bag. The grabbing mechanism is arranged in the sealing box to ensure that the ton bag is always in a sealed environment during lifting, thereby effectively controlling the spread of dust. The grabbing mechanism is drivingly connected to the driving mechanism and moves under the driving of the driving mechanism. The grabbing mechanism is used to grab the ton bag, so that the grabbing mechanism and the driving mechanism closely cooperate through the driving connection, thereby achieving accurate grabbing and lifting of the ton bag and safe transportation in the sealing box, and ensuring that the front-end sealing device can effectively control dust and provide a clean and safe working environment for unpacking.

[0147] The operation process is as follows: first, the driving mechanism is adjusted to a proper position above the sealed box according to the position of the ton bag and the unpacking demand, then the driving mechanism drives the grabbing mechanism to descend until the clamping part of the grabbing mechanism contacts the ton bag, then the clamping part of the grabbing mechanism is closed to firmly grab the ton bag, then the driving mechanism drives the grabbing mechanism to ascend to lift the ton bag into the sealed box or the entrance of the unpacking machine, and finally, after the ton bag reaches the designated position, the driving mechanism controls the clamping part of the grabbing mechanism to open to stably release the ton bag, and prepare for unpacking operation.

[0148] In the embodiment, the front-end sealing device further comprises a dust concentration detection member, which can be a dust concentration detector 100. The dust concentration detection member is arranged in the sealed box and electrically connected with the dust removal device 80. The dust concentration detection member detects the dust concentration in the sealed cavity and controls the start and stop of the dust removal device 80. Specifically, when the dust concentration detection member detects that the dust concentration in the sealed cavity exceeds a preset safety value, it will immediately send a start signal to the dust removal device 80 to trigger the working state of the dust removal device 80. Conversely, when the dust concentration drops below the safety level, the dust concentration detection member will send a stop signal to stop the dust removal device 80 from working, avoiding waste of resources. On the one hand, the above can not only monitor and respond to the change of the dust concentration in the sealed cavity in real time, but also can realize automatic control while ensuring a clean working environment, optimize the operation efficiency of the dust removal device 80, and avoid unnecessary energy consumption, thereby achieving the effects of energy saving and environmental protection; on the other hand, such an automatic control mechanism can also provide a safer and more comfortable working environment for the operator, reducing the safety and environmental risks.

[0149] The dust removal device 80 of the embodiment first performs pre-dust removal treatment before the unpacking work starts, to ensure that the initial dust concentration in the sealed cavity is at a low level. Then, the dust concentration detection member continuously monitors the dust concentration in the sealed cavity, and immediately starts the dust removal device 80 for treatment as soon as the concentration increases. During the entire unpacking process, the dust concentration detection member and the dust removal device 80 work together to ensure stable control of the dust concentration in the sealed cavity, providing a dust-free working environment for the unpacking machine.

[0150] In the embodiment, the front-end sealing device further comprises a centering mechanism, which can be in the form of the aforementioned side pushing assembly 33. The centering mechanism is arranged in the sealing box and below the ton bag grabbing and conveying device 60, and is used for centering the ton bag. Specifically, after the ton bag enters the sealing box from the conveying line, the ton bag can be directly received by the centering mechanism. The centering mechanism can complete the accurate centering of the ton bag in the shortest time, so that the center line of the ton bag is completely aligned with the center line of the grabbing mechanism, thereby ensuring that the grabbing mechanism can accurately grab the ton bag. On the one hand, through accurate centering, the ton bag is prevented from deviating when entering the unpacking machine, unnecessary time waste is reduced, and the overall unpacking efficiency is improved. On the other hand, the safety hazard caused by improper position of the ton bag is reduced, and the stability and safety of the unpacking operation are ensured. Meanwhile, the automatic design of the centering mechanism eliminates the need for manual intervention in the centering process of the ton bag, reduces the labor intensity of the operator, and improves the production automation level.

[0151] Optionally, the arrangement position of the centering mechanism fully considers the natural falling point of the ton bag and the centering requirement of the grabbing mechanism, as long as the ton bag can be smoothly grabbed and finally accurately enter the feed inlet of the unpacking machine.

[0152] As shown in FIGS. 1 and 2, in the embodiment, the front-end sealing device further comprises a conveying line, i.e., the external conveying device 20. The conveying line is designed to be directly communicated with the sealing cavity of the front-end sealing device, so as to ensure that the ton bag can be smoothly and unobstructedly conveyed from the external environment to the inside of the sealing box. On the one hand, the automatic operation of the conveying line reduces the need for manual ton bag carrying, improves the ton bag processing efficiency, and reduces the labor intensity of the operator. On the other hand, the conveying line accurately controls the conveying speed and position of the ton bag, so as to ensure that the ton bag can accurately reach the designated position in the sealing box, thereby providing convenience for the subsequent ton bag lifting and centering operations.

[0153] Optionally, the design of the communication between the conveying line and the sealing cavity needs to consider the size and weight of the ton bag, as well as the inlet size of the sealing box, as long as the accurate conveying docking between the ton bag and the sealing box is ensured.

[0154] In the embodiment, the side of the sealing box is provided with the aforementioned opening and closing door. The conveying line is arranged at the opening and closing door and conveys the ton bag into the sealing box through the opening and closing door. Specifically, the connection between the conveying line and the sealing box is provided with an opening and closing door. During the conveying of the ton bag into the sealing box, the opening and closing door automatically opens at the appropriate time to allow the ton bag to pass through, and immediately closes after the ton bag passes through, so as to quickly restore the sealing state of the sealing box. In this way, the dust generated during the unpacking of the ton bag is effectively controlled from overflowing to the external environment, a cleaner working environment is provided for the operator, and the pollution to the workshop environment is also reduced. The opening and closing door of the embodiment is a roller shutter door.

[0155] The working process of the conveying line and the rolling shutter door: first, in the external storage or transportation area, the ton bag is placed at the starting point of the conveying line, ready to be conveyed into the sealed box, then the operator or the automatic system starts the conveying line, the conveying line starts to work, and the ton bag moves to the sealed box position under the driving of the conveying line; then when the ton bag passes through the communication entrance of the conveying line and the sealed cavity, the rolling shutter door of the sealed box opens according to the preset program or operation instruction to allow the ton bag to pass, and the ton bag can accurately reach the position matched with the ton bag grabbing and transporting device 60 in the sealed box under the precise control of the conveying line, so as to ensure the smooth operation of the subsequent lifting operation, and finally when the ton bag completely enters the sealed box and reaches the specified position, the conveying line stops conveying, and the centering mechanism and the ton bag grabbing and transporting device 60 are started to perform the centering and lifting operation of the ton bag.

[0156] In this embodiment, the side of the sealed box is provided with a dust removal connecting pipe communicating with the sealed cavity, and the dust removal device 80 is arranged at the dust removal connecting pipe. Specifically, the dust removal connecting pipe is arranged at the lower middle position of the side of the sealed box, one end of which directly communicates with the sealed cavity, and the other end communicates with the dust removal device 80. In this way, on the one hand, it ensures that the dust removal device 80 can directly act on the sealed cavity to effectively capture and remove the dust generated in the ton bag processing process; on the other hand, as independent components, the dust removal connecting pipe and the dust removal device 80 are also convenient for daily maintenance and cleaning, that is, when the dust removal device 80 needs to be replaced due to performance degradation or higher dust removal technology is required, the dust removal device 80 can be replaced alone without affecting the normal operation of other parts of the front-end sealing device.

[0157] Optionally, the specific opening position and size of the dust removal connecting pipe are verified by experiments to match the working performance of the dust removal device 80 and the actual needs of the sealed cavity, so as to ensure the dust removal efficiency and the cleanliness of the working environment. The dust removal device 80 also needs to contain various dust removal technologies, such as filter dust removal, electrostatic dust removal, cyclone dust removal, etc., and the specific selection is determined according to the dust characteristics in the sealed cavity, such as dust particle size, concentration and dust removal efficiency requirement, as long as the dust removal effect is ensured.

[0158] In the embodiment, the unpacking machine has the unpacking chamber 10 described above, and the front-end sealing device is arranged on the upstream side of the unpacking machine, and the sealing cavity of the front-end sealing device is arranged in communication with the unpacking chamber 10. Specifically, the unpacking machine is the core component of the unpacking device, responsible for the unpacking and material falling process of the ton bag material. The unpacking machine is internally provided with the unpacking chamber 10, which is a closed space for accommodating the ton bag and performing unpacking operations. The unpacking chamber 10 is usually equipped with material handling tools to achieve efficient unpacking and uniform unloading of the ton bag material. The front-end sealing device is integrally arranged on the upstream side of the unpacking machine, that is, before the ton bag material enters the unpacking chamber 10, it must first pass through the front-end sealing device for pretreatment of the ton bag material. Further, the sealing cavity of the front-end sealing device can be arranged in communication with the unpacking chamber 10, so that the ton bag material can be smoothly transferred from the sealing cavity to the unpacking chamber 10. On the one hand, the integrated design of the front-end sealing device and the unpacking machine realizes the whole process of closing from the ton bag material to the unpacking process, combined with efficient dust removal treatment, significantly reduces the dust concentration in the workshop, improves the working environment, and protects the health of the operators. On the other hand, the ton bag material is pretreated in the sealing cavity to ensure the stability of the material entering the unpacking chamber 10, avoiding safety hazards caused by improper material position. At the same time, the automation of the front-end sealing device combined with the efficient unpacking process of the unpacking machine improves the automation level and processing efficiency of the whole unpacking process, and reduces the production cost.

[0159] Optionally, the design of the unpacking chamber 10 of the unpacking machine needs to ensure the closure during the unpacking process, and ensure that the front-end sealing device forms a whole process of closing and dust control from the material entering to the material unpacking. At the same time, the unpacking chamber 10 is usually equipped with material handling tools, usually cutting devices, vibrating screens and other devices, and other related tools can also be added as needed, as long as the unpacking operation can be completed.

[0160] In the embodiment, the ton bag grabbing and transporting device 60 of the front-end sealing device is movably arranged between the unpacking machine and the sealing box, and can drive the ton bag to be transported from the sealing box to the unpacking machine, which means that the lifting device is not fixed at a single position, but can move freely between the unpacking machine and the sealing box to adapt to the lifting and transfer requirements of the ton bag. On the one hand, it avoids the need for manual handling of the ton bag, reduces labor intensity, and also reduces the spread of dust and material loss caused by human operation, improving safety. On the other hand, the ton bag grabbing and transporting device 60 precisely docks with the unpacking machine to smoothly transfer the ton bag material from the sealing box to the inside of the unpacking machine, reducing the delay and loss of the ton bag material during the transfer process, ensuring the timeliness of material transfer, and improving the unpacking efficiency.

The collecting jacking assembly 53 is arranged in the second operation area 132, which has a docking port, i.e., the edge structure. The collecting jacking assembly 53 lifts the box body 521 to the docking port and docks with the waste bag generating device, and the waste bag falls into the box body 521 through the docking port.

[0191] The waste bag recycling device in this embodiment further includes an inspection port located on the side of the third chamber 13.

[0192] The embodiment sets the outer bag conveying assembly 51, the cover opening assembly 54 and the collection jacking assembly 53 in the operation area to realize automatic opening and conveying of the box 521 and finally docking with the waste bag generating device. Specifically, the box 521 is part of the collection box 52, the shell forms the operation space of the entire waste bag recycling device, and the first operation area 131 and the second operation area 132 adjacent to the first operation area 131 are sequentially formed, the first operation area 131 and the second operation area 132 are connected in communication, and the outer bag conveying assembly 51 is arranged below the first operation area 131 and the second operation area 132, so that the outer bag conveying assembly 51 drives the box 521 to convey between the first operation area 131 and the second operation area 132. The cover opening assembly 54 is arranged in the first operation area 131, which opens or closes the cover 522 of the box 521. The cover opening assembly 54 is arranged in the first operation area 131, which opens or closes the cover 522 of the box 521. The second operation area is provided with a docking port at the upper portion and a collection jacking assembly 53 at the lower portion, so that the box 521 without the cover 522 in the second operation area 132 moves upward and docks with the waste bag generating device at the docking port to receive the waste bag into the box 521. The specific working process is as follows: the box 521 is conveyed by the outer bag conveying assembly 51 to the first operation area 131 inside the shell, the cover opening assembly 54 in the first operation area 131 opens the cover 522 of the box 521, then the outer bag conveying assembly 51 continues to convey the box 521 without the cover 522 to the second operation area 132, at this time the collection jacking assembly 53 in the second operation area 132 starts jacking work and lifts the box 521 without the cover 522 to the docking port at the upper portion of the second operation area 132, finally the waste bag generated by the waste bag generating device falls into the box 521 through the docking port, when the box 521 is full of waste bags or one-time bagging is completed, the collection jacking assembly 53 drives the box 521 to fall back to the outer bag conveying assembly 51 below the second operation area 132, and the outer bag conveying assembly 51 drives the box 521 full of waste bags to return from the second operation area 132 to the first operation area 131, the cover opening assembly 54 in the second operation area 132 continues to work and re-covers the cover 522 on the upper portion of the box 521, and finally the outer bag conveying assembly 51 conveys the box 521 to the outside of the shell.In the above aspect, the automatic design of the outer bag conveying assembly 51, the cover opening assembly 54, and the collection jacking assembly 53 realizes automatic transportation, cover opening, and jacking docking of the box body 521 during the waste bag recycling process, greatly improves the operation efficiency, reduces the labor demand, and reduces the processing cost. On the other hand, the closed design of the shell and the division of the operation area effectively control the pollution during the waste bag recycling process, reduce the impact on the operating environment, and at the same time reduce the direct contact of the operator with the waste bag, thereby improving the operation safety.

[0193] As shown in FIGS. 26, 28, 30, 32, and 33, in the present embodiment, the cover opening assembly 54 includes a support mechanism 541 and a lifting mechanism 542. At least a part of the support mechanism 541 is movably arranged in the first operation area 131 and can be docked with the operation end 523 of the cover body 522, which is to provide stable support when the cover body 522 is opened, so as to avoid the cover body 522 from shaking or tilting during the opening process, thereby ensuring the safety and reliability of the operation. The lifting mechanism 542 is drivingly connected with the box body 521 or the support mechanism 541 and drives the lifting movement of the box body 521 or the support mechanism 541, so that the cover body 522 of the box body 521 is docked with the support mechanism 541, and the support mechanism 541 can support the cover body 522 at a predetermined height, thereby realizing the opening of the cover body 522. The present embodiment adopts the driving cooperation form between the lifting mechanism 542 and the box body 521. Specifically, when it is needed to open the cover body 522, the lifting mechanism 542 drives the upward movement of the box body 521 to a predetermined position, and then the support mechanism 541 extends. At this time, the support mechanism 541 is located below the operation end 523 and can support the cover body 522 at the predetermined position. Then the lifting mechanism 542 drives the downward movement of the box body 521, and the box body 521 falls back to the outer bag conveying assembly 51, thereby completing the opening of the cover body 522. The aforementioned collection jacking assembly 53 can be used as the lifting mechanism 542, or a separate lifting mechanism 542 can be additionally provided.

[0194] In addition to the above driving cooperation between the lifting mechanism 542 and the box body 521, the driving cooperation between the lifting mechanism 542 and the supporting mechanism 541 can also be adopted. Specifically, the supporting mechanism 541 of the cover opening assembly 54 and the lifting mechanism 542 work together, so that the cover body 522 can be automatically opened and closed in the first operation area 131. When opening the cover body 522, the lifting mechanism 542 is located at a height position slightly lower than the operation end 523, the supporting mechanism 541 is driven to extend into the directly below of the operation end 523, then the supporting mechanism 541 rises to the operation end 523 of the cover body 522, then the supporting mechanism 541 continues to lift, so that the cover body 522 is separated from the box body 521 and is fixed at a predetermined height by the supporting mechanism 541; when closing the cover body 522, the lifting mechanism 542 drives the supporting mechanism 541 to descend, so that the cover body 522 is reconnected with the box body 521, the supporting mechanism 541 exits the directly below of the operation end 523, and the sealing is completed. The design of the cover opening assembly 54 not only greatly reduces the need for manual operation, improves the automation degree of the waste bag collection process, but also ensures the safety of the operation process and the maintenance of the dust-free environment.

[0195] Optionally, the connection between the supporting mechanism 541 and the cover body 522 can be realized by precise positioning devices, such as sensors, visual recognition systems or mechanical positioning pins, and the lifting mechanism 542 can be a hydraulic cylinder, an electric push rod, a gear and rack system or other driving devices capable of realizing vertical movement, and the lifting mechanism 542 should have sufficient lifting force, as long as it can ensure that the box body 521 or the supporting mechanism 541 can be lifted to a predetermined height.

[0196] As shown in FIG. 32 and FIG. 33, in the present embodiment, the supporting mechanism 541 comprises a supporting plate 543 and a supporting driving member 544, the supporting plate 543 is the main part of the supporting mechanism 541, designed as a transversely movable structure, and extends into the lower side of the operation end 523 of the cover 522 in the first operation area 131 to provide necessary support for the cover 522. The supporting driving member 544 is drivingly connected with the supporting plate 543 and drives the supporting plate 543 to move transversely to realize the interfacing and separating with the operation end 523 of the cover 522. In this way, when it is needed to open the cover 522, first the lifting mechanism 542 drives the box 521 to rise to a predetermined position, then the supporting driving member 544 drives the supporting plate 543 to move transversely into the lower side of the operation end 523 until the supporting plate 543 completely interfaces with the bottom of the operation end 523 of the cover 522, the lifting mechanism 542 drives the box 521 to descend, and the cover 522 is supported by the supporting plate 543 during the descending process of the box 521, the box 521 falls back to the outer bag conveying assembly 51, at this time the box 521 is in the open cover state; when it is needed to close the cover 522, the lifting mechanism 542 drives the box 521 to rise, and during the process of approaching the cover 522, the supporting driving member 544 drives the supporting plate 543 to retract transversely to remove the support for the cover 522, the cover 522 reinterfaces with the box 521 under the action of gravity to complete the sealing.

[0197] Optionally, the supporting plate 543 can be made of a solid metal material to bear the weight of the cover 522, and the surface of the supporting plate 543 can be covered with an anti-skid material to increase the friction force of the contact surface with the cover 522, further improving the stability of the support, as long as it can stably support the cover 522 when the cover 522 is opened to prevent the cover 522 from shaking or accidentally falling in the opened state. At the same time, the supporting driving member 544 can be an electric push rod, a hydraulic cylinder, a screw transmission mechanism or other driving devices capable of realizing linear motion, as long as it can ensure that the supporting driving member 544 has sufficient pushing and pulling force to stably drive the supporting plate 543 to move transversely during the opening and closing process of the box 521 and the cover 522.

[0198] In the embodiment, the lifting mechanism 542 is arranged below the first operation area 131, the top of the lifting mechanism 542 is provided with a support table 545 for supporting the box 521, the box 521 is supported on the support table 545 when being transported into the first operation area 131, the lifting mechanism 542 drives the whole box 521 to rise, and drives the remaining part of the box 521 to descend after the cover 522 is supported by the supporting mechanism 541. Specifically, the lifting mechanism 542 comprises the support table 545, a jacking cylinder, a mounting bracket and a controller, the jacking cylinder is fixed on the mounting bracket, the cylinder rod of the jacking cylinder is connected with the support table 545, when the waste bag recycling device starts to work, the box 521 is sent to the lower part of the first operation area 131 by the outer bag conveying assembly 51, at this time, the bottom of the box 521 is directly placed on the support table 545 of the lifting mechanism 542. When it is needed to open the cover 522 of the box 521, the controller is opened, the jacking cylinder is started, the support table 545 and the whole box 521 are driven to rise, until the operation end 523 of the cover 522 of the box 521 is connected with the support plate 543 of the supporting mechanism 541, after the cover 522 is successfully supported by the support plate 543 of the supporting mechanism 541, the jacking cylinder is axially retracted to drive the support table 545 to descend, at this time, only the bottom and the side of the box 521 are driven to descend on the outer bag conveying assembly 51. In this way, the cooperative work of the lifting mechanism 542 and the supporting mechanism 541 can not only improve the automation degree of the waste bag collection process, but also can ensure the safety and stability of the operation, and provides a guarantee for the efficient operation of the waste bag recycling device. It should be noted that the remaining part of the box 521 refers to the other part of the box 521 after the cover 522 is opened, that is, the bottom and the side of the box 521.

[0199] As shown in FIG. 29, in the present embodiment, the upper surface of the support table 545 is provided with a first positioning structure for cooperating with the protrusion 524 at the bottom of the box 521. The purpose of this structure is to precisely dock with the protrusion 524 at the bottom of the box 521, thereby achieving stable positioning of the box 521 during lifting, avoiding shaking or deviation of the box 521 during lifting or lowering. The first positioning structure has a first positioning slope for positioning with the inclined surface of the protrusion 524. The slope is used to position with the inclined surface of the protrusion 524 at the bottom of the box 521. When the box 521 is sent into the support table 545 by the outer bag conveying assembly 51, the inclined surface of the protrusion 524 at the bottom of the box 521 will contact the first positioning slope on the support table 545, and during the lifting or lowering of the box 521 by the lifting mechanism 542, the box 521 will be guided to be precisely positioned in the first positioning structure through the relative sliding between the slopes, achieving stable positioning of the box 521. In this way, through the precise cooperation of the support table 545 and the bottom of the box 521 by the first positioning structure and the first positioning slope, not only the accuracy and stability of the box 521 during lifting can be improved, but also the safety of operation can be ensured, providing protection for the stable and efficient operation of the waste bag recycling device. At the same time, it also reduces the operation failure that may be caused by inaccurate positioning of the box 521, prolongs the service life of the equipment, and reduces the maintenance cost.

[0200] In the embodiment, the supporting mechanism 541 is multiple, and the first operation area 131 is provided with the supporting mechanism 541 on opposite sides. Specifically, the supporting mechanism 541 is not single position but multiple, and is distributed on opposite sides of the first operation area 131, and each supporting mechanism 541 includes a supporting plate 543 and a supporting driving element 544, which cooperates to support the cover 522 of the box 521. The multiple supporting mechanisms 541 can evenly distribute the weight of the cover 522 when opened, avoid the structural stress concentration problem that may be caused by single-point support, and ensure the balance of the cover 522 after opening, avoid the inclination or shaking that may be caused by single-side support, thereby improving the stability and safety of the opening operation, and reducing the operation risk. When the box 521 opens the cover 522 in the first operation area 131, the supporting driving element 544 on both sides drives the supporting plate 543 to move horizontally into the lower side of the operation end 523 of the cover 522, and the supporting plate 543 is completely connected with the bottom of the cover 522. Due to the supporting effect of the multiple supporting mechanisms 541, the cover 522 is stably hung at a predetermined height, forming a balanced and stable opening state. Similarly, when the cover 522 needs to be closed on the box 521, the supporting driving element 544 on both sides drives the supporting plate 543 to move horizontally out, and the support of the cover 522 is released, ensuring the smooth transition of the cover 522 in the closing process, avoiding the problem of loose closing or damage of the cover 522 that may be caused by single-side support. The above supporting mechanism 541 is designed to be multiple on both sides, which can not only improve the operation accuracy and reduce the safety hidden danger that may be caused by improper operation, but also ensure the integrity of the cover 522 in the opening and closing process, prolong the service life of the equipment, and reduce the maintenance cost.

[0201] The cover 522 of the embodiment can be a steel shell, and a sealing strip is pasted inside. When it needs to be covered, it is placed above the collection box 52 to prevent dust overflow of the collection box 52 during transportation.

[0202] As shown in FIG. 27, in the present embodiment, the waste bag recycling device further comprises a centering device 55, which is connected with the outer bag conveying assembly 51 and located in the first operation area 131. When the box 521 is located in the first operation area 131, the centering device 55 pushes the box 521 to center the position of the box 521. Specifically, the centering device 55 is arranged on both sides of the box 521 to ensure that the centering device 55 contacts the side surface of the box 521 and can stably control the position of the box 521 when pushing the box 521. In this way, when the box 521 enters the first operation area 131, the centering device 55 accurately adjusts the position of the box 521 to ensure that the box 521 can be accurately docked with other components such as the cover opening assembly 54 and the lifting mechanism 542. On the one hand, the above improves the automation degree of the waste bag collection process and the safety of the operation; on the other hand, it can reduce the operation failure that may be caused by the position deviation, at the same time, improve the operation efficiency of the equipment, reduce the maintenance cost, and provide a guarantee for the efficient operation of the waste bag recycling device. The centering device 55 of the present embodiment is provided in two and distributed on the opposite sides of the conveying direction of the outer bag conveying assembly 51 in the first operation area 131.

[0203] As shown in FIG. 31, in the present embodiment, the collection jacking assembly 53 comprises a jacking support 531, a jacking platform 532 and a jacking driving component 533. Specifically, the jacking support 531 serves to support the entire jacking platform 532 and the jacking driving component 533, ensuring the stability of the jacking operation and the structural stability. The jacking platform 532 is connected to the jacking support 531 in a lifting manner, and the box 521 is supported on the jacking platform 532 when it is located in the second operation area 132. The upper surface of the jacking platform 532 is provided with a second positioning structure 534 for cooperating with the protrusion 524 at the bottom of the box 521, ensuring the stable positioning of the box 521 during the jacking process. The jacking driving component 533 is drivingly connected to the jacking platform 532 and drives the jacking platform 532 to lift, so that the box 521 on the jacking platform 532 can be lifted to an appropriate height in the second operation area 132, so that the waste bag can be smoothly dropped into the box 521 for processing. In this way, when the box 521 needs to be operated in the second operation area 132, the box 521 is first conveyed to the outer bag conveying assembly 51 above the jacking platform 532. At this time, the protrusion 524 at the bottom of the box 521 is positioned and cooperated with the second positioning structure 534 on the upper surface of the jacking platform 532, realizing the stable support of the box 521 during the jacking process. Then the jacking driving component 533 drives the jacking platform 532 to stably rise until the box 521 reaches the docking port, so as to facilitate the subsequent waste bag processing and other operations. When the waste bag packaging is completed, the jacking driving component 533 is started again to drive the jacking platform 532 to stably descend until the bottom of the box 521 completely touches the support surface of the outer bag conveying assembly 51. The above not only can improve the accuracy of the jacking process of the box 521, realize the accurate positioning of the box 521 at the docking port, and reduce the safety hazards that may be caused by improper operation, but also can ensure the stability of the box 521 during the jacking and descending processes.

[0204] In the present embodiment, the second positioning structure 534 comprises a plurality of positioning blocks, the positioning blocks are provided with second positioning slopes 535 for cooperating with the inclined surfaces of the protrusions 524, the inclined directions of the second positioning slopes 535 are the same as the inclined directions of the inclined surfaces of the protrusions 524, and the protrusions 524 are positioned in the positioning areas between the positioning blocks. This design can utilize the contact between the slopes to guide the smooth transition of the box body 521 during the lifting or lowering process of the lifting platform 532, and avoid the shaking or deviation of the box body 521. Specifically, the plurality of positioning blocks are uniformly distributed on the lifting platform 532, the second positioning slopes 535 of the positioning blocks are opposite to each other so that a positioning area is formed between the second positioning slopes 535, and the size and position of the positioning area are matched with the size and position of the protrusions 524 at the bottom of the box body 521, so as to ensure that each protrusion 524 can contact and cooperate with the second positioning slope 535 of at least one positioning block. In this way, when the box body 521 is conveyed above the lifting platform 532, the protrusions 524 at the bottom of the box body 521 will contact the second positioning slopes 535 of the positioning blocks. With the start of the lifting driving component 533, the lifting platform 532 starts to rise, and the protrusions 524 slide along the inclined direction of the second positioning slopes 535 until the protrusions 524 are completely positioned in the positioning area between the positioning blocks. At this time, the position of the box body 521 on the lifting platform 532 is accurately adjusted, and the accurate docking of the box body 521 with other parts of the waste bag recycling device is ensured. Above, through the joint action of the plurality of positioning blocks, the stability of the box body 521 during the lifting process is improved, and the support imbalance or position deviation that may be caused by single-point contact is avoided. The positioning blocks of the present embodiment are provided with two, and the second positioning slopes 535 are correspondingly provided with two.

[0205] In the embodiment, the outer bag conveying assembly 51 is a bidirectional conveying assembly, the outer bag conveying assembly 51 has a first conveying direction from the first operation area 131 to the second operation area 132 and a second conveying direction opposite to the first conveying direction, and the outer bag conveying assembly 51 can drive the box body 521 to move along the first conveying direction and the second conveying direction. In this way, when the box body 521 needs to be conveyed from the first operation area 131 to the second operation area 132 and the cover body 522 is opened, the controller starts the outer bag conveying assembly 51 and drives the outer bag conveying assembly 51 to move along the first conveying direction, i.e., from the first operation area 131 to the second operation area 132, and the box body 521 moves stably on the outer bag conveying assembly 51 until it reaches the second operation area 132; after the waste bag collection in the second operation area 132 is completed, the box body 521 needs to return to the first operation area 131 for resealing. At this time, the controller switches the running direction of the conveying device and drives the outer bag conveying assembly 51 to move along the second conveying direction, i.e., in the direction opposite to the first conveying direction. The box body 521 moves reversely along the outer bag conveying assembly 51 until it returns to the first operation area 131. Through the above arrangement of the outer bag conveying assembly 51, on the one hand, the box body 521 can be efficiently and automatically conveyed between the first operation area 131 and the second operation area 132, avoiding the cumbersome operation of manually carrying the box body 521; on the other hand, the automation degree and the processing efficiency of the waste bag recycling device are improved, and the labor intensity of the operator is reduced, the working safety is improved. The outer bag conveying assembly 51 in the embodiment is achieved by adopting a bidirectional motor driving mode, and bidirectional conveying is achieved by forward and reverse rotation of the bidirectional motor.

[0206] As shown in FIG. 26, in the present embodiment, the outer bag conveying assembly 51 comprises a first conveying part 511 and a second conveying part 512. The housing cover is arranged above the first conveying part 511. The side of the first operation area 131 away from the second operation area 132 is the entrance side. The second conveying part 512 is located outside the housing and at the entrance side. The housing has a hinged door which is located at the entrance side to shield the entrance side. Specifically, the first conveying part 511 is a conveying mechanism located inside the housing, responsible for conveying the box 521 from the entrance side of the first operation area 131 to the second operation area 132, or from the second operation area 132 back to the exit side of the first operation area 131. The housing cover is arranged above the first conveying part 511 to form a closed conveying channel, so as to protect the box 521 during conveying and prevent waste from escaping during conveying, keeping the operating area clean. The second conveying part 512 is located outside the housing and corresponds to the entrance side of the first conveying part 511. Its function is to send the box 521 into the first conveying part 511 inside the housing from the entrance side, or to send the box 521 out of the first conveying part 511 inside the housing. The hinged door temporarily closes the housing. When the box 521 needs to enter the housing, the second conveying part 512 sends the box 521 smoothly into the entrance side of the first conveying part 511. At this time, the hinged door is opened to allow the box 521 to pass through, and then closed to keep the operating area closed. When the box 521 needs to be removed from the housing, the hinged door is opened, and the second conveying part 512 receives the box 521 from the first conveying part 511 and conveys it to the operator or subsequent processing equipment. Through the design of the first conveying part 511 and the second conveying part 512, not only the conveying efficiency of the box 521 between different operation areas is improved, and manual intervention is reduced, but also the operating environment is kept clean and waste leakage is prevented.

[0207] As shown in FIG. 27, in the present embodiment, the first conveying part 511 comprises a conveying support 513, a conveying part 514, a conveying driving part 515, a detection part 516 and a limiting part 517. Specifically, the conveying support 513 is the basic support structure of the first conveying part 511, which comprises a containing area for containing the collection jacking assembly 53, the size and shape of the containing area are matched with the collection jacking assembly 53, which ensures that the collection jacking assembly 53 can run smoothly under the conveying part 514 to perform the jacking operation of the box 521. The conveying part 514 is the main working part of the first conveying part 511, which can be rotatably arranged along the conveying support 513 to realize the continuous conveying of the box 521. The conveying driving part 515 is drivingly connected with the conveying part 514, which serves as the power source of the conveying part 514 and drives the rotation of the conveying part 514; the detection part 516 is arranged on the side of the conveying support 513 and is used to detect the position of the box 521 on the conveying part 514, which ensures the accurate conveying of the box 521; the limiting part 517 is arranged at the end of the conveying support 513 and is used to abut against the box 521 when the box 521 is conveyed to the limit position, so as to prevent the box 521 from exceeding the predetermined conveying range due to excessive conveying speed or improper control. The above arrangement of the first conveying part 511 not only ensures that the first conveying part 511 provides efficient, stable and accurate conveying for the box 521 of the waste bag recycling device, but also improves the automation degree of the conveying process, ensures the position stability of the box 521 during the conveying process, prevents the box 521 from exceeding the predetermined conveying range, and provides protection for the efficient operation and operation safety of the waste bag recycling device. The conveying part 514 of the present embodiment is specifically a chain structure, the conveying driving part 515 is the aforementioned bidirectional motor, and the detection part 516 is a photoelectric switch.

[0208] Alternatively, the limiting part 517 can be an elastic stopper, a positioning pin or a limit switch, etc., which can reliably block the box 521 and will not cause damage to the box 521 or the conveying part 514 when the box 521 contacts the limiting part 517; the detection part 516 can be a displacement sensor or a contact sensor, etc., which ensures the accurate conveying of the box 521. In addition, the conveying driving part 515 can also use a hydraulic motor or a pneumatic motor, etc. according to actual needs, and the power thereof should be sufficient to drive the continuous operation of the conveying part 514 under load conditions. The conveying part 514 can also be a belt drive or a gear drive, as long as the stability and transmission efficiency of the box 521 during the conveying process are ensured.

[0209] The main process steps of the ton bag unpacking system of the present embodiment are as follows when used:

[0210] 1. Initial state of the device: ton bag grabbing and transporting device 60 is located above side pushing assembly 33, zero point calibration switch of horizontal walking front end detection unit 671 feeds back signal, vertical lifting structure 65 is lifted to high point, zero point calibration switch of lifting structure upper end detection unit 656 feeds back signal; cylinder of locking mechanism 63 is retracted, locking mechanism 63 is in open state; cylinder of collecting jacking assembly 53 is extended, and collecting box 52 is tightly jacked on sealing strip of third chamber 13 closing structure;

[0211] 2. The ton bag placed on the support is moved by the forklift to the external conveying device 20, at this time, the photoelectric detection group and the grating detection group distinguish whether the object entering the detection area is a person or goods through detection logic judgment;

[0212] 3. The opening and closing door at the front end of the first chamber 11 of the second chamber 12 is opened, the external conveying device 20 is started and feeds back signal, the roller flow line 21 of the external conveying device 20 is started, and the support is conveyed forward from the roller flow line 21 to the chain conveying line of the internal conveying device 30;

[0213] 4. The ton bag is detected by the front angle photoelectric detection switch, and after a delay, the ton bag laser range finder measures the distance to the ton bag at this time and records it as value A; the support continues to move forward on the chain conveying line of the internal conveying device 30, the rear angle photoelectric detection switch detects the ton bag leaving the detection area, and the ton bag laser range finder measures the distance to the ton bag at this time and records it as value B;

[0214] 5. The ton bag to position detection switch detects the ton bag to the deviation correction area, the chain conveying line of the internal conveying device 30 stops, and the opening and closing door at the front end of the first chamber 11 of the second chamber 12 is closed;

[0215] 6. The ton bag jacking structure movable plate supports the support to leave the chain conveying line of the internal conveying device 30, the ton bag jacking structure movable plate supports the support to leave the chain conveying line of the internal conveying device 30; the front pushing structure cylinder is extended, and the ton bag is pushed backward on the ton bag jacking structure top plate along with the ton bag jacking structure movable plate, and enters the deviation correction area;

[0216] 7. The ton bag is clamped to the axis position by the extension of the deviation correction device cylinder; the system calculates the A and B values calculated in the previous step by the ton bag laser range finder, and when A-B does not meet the predetermined condition, it is judged that the ton bag is not inclined and does not need to be corrected obliquely; when A-B meets the predetermined condition, it is judged that the ton bag is inclined, at this time, the side pushing assembly 33 acts, and the ton bag rotates to the right position under the action of the diagonal thrust. After the ton bag is corrected, the corresponding side pushing assembly 33 is retracted and feeds back the in-place signal;

[0217] 8. The ton bag grabbing and transporting device 60 moves downward under the action of the vertical lifting structure 65, stops and sends a feedback signal after reaching a designated height above the ton bag; the cylinders of the multiple hook ends 62 on the ton bag grabbing and transporting device 60 extend, the hook ends 62 and the locking mechanism 63 are pressed against the outer side of the ton bag, and the cylinders send a feedback signal indicating that they are in position; the vertical lifting structure 65 drives the ton bag grabbing and transporting device 60 to move upward, the multiple hook ends 62 move upward along the side of the ton bag, and the side strap of the ton bag is guided onto the hook ends 62. As the ton bag grabbing and transporting device 60 gradually moves upward, the ton bag is gradually lifted away from the support; at this time, the weighing device 64 judges the weight. Considering the offset, when the weight displayed by all the weighing devices 64 is greater than 1 / 8 of the weight of the ton bag, it is considered that the bag is successfully hung. The locking device 631 moves down and locks the bag strap with the hook end 62, completing the automatic bag hanging action;

[0218] 9. If the weight displayed by one or more weighing components 64 is less than 1 / 8 of the ton bag weight, the bag hanging is considered a failure. After the ton bag grabbing and transporting device 60 moves downward a specified distance, the cylinder of the hook end 62 retracts and sends a feedback signal. The hook end 62 opens and resets, and the vertical lifting structure 65 moves upward back to the starting position. If the ton bag correction is not performed the first time, the system determines whether AB is positive or negative, and the side push component 33 performs correction. If correction is performed in one direction the first time, correction in the other direction is performed again. After correction is completed, the bag hanging and weight judgment process is repeated. If the bag hanging judgment fails, after the hook end 62 opens and resets, and the vertical lifting structure 65 moves upward back to the starting position, the ton bag correction action is performed in the opposite direction to the previous one. After correction is completed, the bag hanging and weight judgment process is repeated. If the system still indicates bag hanging failure after the above bag hanging and correction are performed 3 times, an alarm will be issued, requiring personnel to stop the machine for judgment and intervention.

[0219] 10. After the automatic bag hanging is completed, the vertical lifting structure 65 moves upward and returns to the starting position. The centrifugal fan of the dust removal device 80 is turned on, and a slight negative pressure environment is formed in the second chamber 12. The front door of the second chamber 12 opens and sends a feedback signal to the position. The pre-blowing component 41 introduces compressed air to blow the ton bag at the entrance of the front door of the second chamber 12 at high speed.

[0220] 11. The servo motor of the lateral travel drive component 672 starts, and the ton bag grabbing and transporting device 60 lifts the ton bag and moves it into the second chamber 12. When the ton bag passes the pre-blowing component 41, foreign objects at the bottom are blown off by the high-speed compressed air. The system calculates that the servo motor of the lateral travel drive component 672 is precisely positioned directly above the bag-breaking knife 42 and sends a positioning signal. The pre-blowing component 41 stops supplying compressed air, the second chamber 12 closes, the scraper component 46 motor starts, the scraper in the buffer chamber 45 rotates, and the ton bag reaches the bag-breaking area above the bag-breaking knife 42. The program then enters the bag-breaking process.

[0221] 12. The vertical lifting structure 65 moves downward, and the bottom of the ton bag starts to contact the bag-breaking knife 42. As the vertical lifting structure 65 continues to move downward, the ton bag is gradually cut by the eight groups of blades embedded in the bag-breaking knife 42 due to its own weight, and the bottom packaging bag of the ton bag is cut open. When the ton bag completely falls onto the knife rest, the bottom packaging of the ton bag is cut into a "rice" - shaped opening area. At this time, the vertical lifting structure 65 stops moving. The blowing pipe 43 is supplied with compressed air, and the high - speed compressed air is blown into the ton bag to fluidize the powder. The vertical lifting structure 65 slowly and continuously moves upward. The "rice" - shaped opening at the bottom of the ton bag gradually opens under the action of the gravity of the powder, and the powder in the ton bag is carried out by the compressed air of the blowing pipe 43. When the bottom of the ton bag reaches the air outlet of the blowing pipe 43, the lifting stops, and the ton bag remains in a hovering state. The blowing pipe 43 continues to supply compressed air, and the powder in the ton bag continues to be fluidized and continuously flows out downward. The flapping component 44 swings reciprocally driven by the cylinder of the swinging flapping drive unit, continuously knocking on the bottom of the ton bag to assist the powder to flow out faster. The powder falls into the lower buffer bin 45. According to different powder characteristics, the left and right groups of the flapping component 44 can be synchronized, can be alternated; or the ton bag can move up and down reciprocally when the flapping component 44 flaps to accelerate the powder discharging speed; the program enters the discharging process;

[0222] 13. The weighing component 64 monitors the weight of the ton bag at any time. When the total weight is less than 20 Kg, it enters the residue cleaning stage. The blowing pipe 43 stops supplying compressed air, and the vertical lifting structure 65 moves upward so that the lower discharging port of the ton bag脱离 the area of the bag - breaking knife 42. The flapping component 44 continues to flap the bottom of the ton bag for 15 times and then stops. The ton bag hovers, and the weighing component 64 feeds back the weight value C at this time. When C > ton bag tare weight + allowable residual weight, the flapping component 44 flaps the bottom of the ton bag for another fifteen times and then feeds back the value C until C ≤ ton bag tare weight + allowable residual weight; the flapping component 44 resets; in the residue cleaning stage, the continuous flapping times of the flapping component 44 are set personalized according to the powder characteristics;

[0223] 14. The scraper in the buffer bin 45 rotates continuously, and the falling powder is continuously pushed by the scraper component 46 to the discharging port of the buffer bin 45 and enters the lower automatic iron remover 47, and is transported through the acceleration chamber and the negative pressure pipeline;
