Description

Technical Field

[0001] The invention relates to the field of new energy technology, and in particular to a bottom-breaking package unpacking machine. Background Art

[0002] With the development of the new energy industry, the market demand for lithium batteries is increasing day by day.

[0003] In the lithium battery industry, the powder required for lithium battery production is mainly packaged and transported in lifting bags, such as ton bags. Ton bags are large packaging bags used for lifting and transportation. They are of high quality, low price and strong structure. During the material preparation or feeding stage, the powder contained in the ton bag needs to be transferred to the silo.

[0004] At present, in the whole feeding operation process, it is necessary to carry out the bag breaking process, material unloading process, waste bag recycling process, waste bag collection and transportation process and other processes in sequence. Among them, in the bag breaking process, usually after the transport device transports the ton bag to the unpacking station, the ton bag rope is manually untied or the ton bag is directly cut with the help of a knife; in the material unloading process, usually the untied or cut ton bag is directly dropped into the feed bin by gravity, and then the waste bag is screened out by a rotary screen or a vibrating screen; in the waste bag recycling process, usually the screened waste bags are folded and compressed manually; in the waste bag collection and transportation process, usually a certain amount of ton bags collected by workers are regularly transported by waste collection vehicles. However, there is a lot of manual labor intervention in the whole feeding operation process, resulting in high labor costs and low work efficiency. In the bag breaking process and waste bag recycling process, the powder is easy to form dust, resulting in a bad working environment and causing great harm to the health of workers.

[0005] Therefore, how to efficiently complete the feeding operation, reduce manual labor, reduce labor costs, and improve the degree of mechanization of the operation, while trying to avoid dust generation during the operation, improve the working environment, and reduce harm to the health of workers, is a technical problem faced by technical personnel in this field.

[0081] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0082] Please refer to Figure 1 , Figure 2 , Figure 1 This is a schematic diagram of the overall structure of a specific implementation method provided by the present invention. Figure 2 for Figure 1 Axonometric drawing of the local structure.

[0083] In a specific embodiment provided by the present invention, the bottom breaking type bag unpacking machine mainly includes a frame 1, a bag breaking chamber 2, a recovery chamber 3, a lower bin 4, a collection box 5, a bag breaking device 6, a flow aid device 7, a recovery device 8 and a lifting device 9.

[0084] Among them, the frame 1 is the main structural part of the bottom breaking unpacking machine, which is mainly used to install and carry other parts.

[0085] The bag breaking chamber 2 and the recovery chamber 3 are both installed on the frame 1, and both the bag breaking chamber 2 and the recovery chamber 3 are closed cavities. The bag breaking chamber 2 is mainly used to provide a closed working environment for the bag breaking device 6 and the flow-aiding device 7, and the recovery chamber 3 is mainly used to provide a closed working environment for the recovery device 8, so as to prevent indoor dust from spilling into the external environment through the closed working environment.

[0086] like Figure 8 As shown, Figure 8 The specific structural diagram of the lower material bin 4 is shown in FIG. The lower material bin 4 is connected to the bottom of the bag breaking chamber 2. When the lifting bag is broken by the bag breaking device 6 in the bag breaking chamber 2, the powder contained in the lifting bag will fall into the lower material bin 4 through the bottom through hole of the bag breaking chamber 2 to achieve material storage.

[0087] The collection box 5 is connected to the bottom of the recovery chamber 3. When the waste bags are compressed and discharged by the recovery device 8 in the recovery chamber 3, the waste bags fall into the collection box 5 through the through hole (bag opening) at the bottom of the recovery chamber 3, thereby realizing the collection of the waste bags.

[0088] The bag breaking device 6 is arranged in the lower material bin 4 , and is mainly used to break the bag to make the powder contained in the lifting bag fall into the lower material bin 4 .

[0089] The flow-aiding device 7 is arranged in the bag breaking chamber 2, and is mainly used to repeatedly beat the hanging bag after the bag is broken to form vibration, so that the powder accumulated or even agglomerated in the hanging bag can be quickly loosened and dispersed under the action of vibration, and the flow of the powder can be enhanced, and then it can continuously flow out from the bottom of the hanging bag and fall into the unloading bin 4, so as to realize rapid unloading.

[0090] The recovery device 8 is disposed in the recovery chamber 3 , and is mainly used to compress the waste bags and discharge them into the collection box 5 .

[0091] The lifting device 9 is arranged on the frame 1 and has multiple degrees of freedom of movement. It can move horizontally and vertically. It is mainly used to grab the lifting bag and lift the lifting bag to the bag breaking chamber 2 or the recovery chamber 3 according to the process requirements.

[0092] Thus, the bottom-breaking unpacking machine provided in this embodiment has the following feeding process: first, the lifting bag is grabbed by the lifting device 9 and lifted into the bag breaking chamber 2, and the bag is broken by the bag breaking device 6 in the bag breaking chamber 2, and then the flow-aiding device 7 is started to repeatedly beat the lifting bag to form vibration, so as to achieve rapid and residue-free unloading; after unloading is completed, the lifting bag is continued to be lifted into the recovery chamber 3 by the lifting device 9, and the waste bag is compressed by the recovery device 8 in the recovery chamber 3, and then the waste bag is discharged into the collection box 5, and finally collected and transported by the collection box 5.

[0093] Compared with the prior art, the bottom-breaking bag unpacking machine provided in this embodiment, during the entire feeding operation, important processes such as the bag breaking process, the material unloading process, and the waste bag recovery process are independently completed in the bag breaking chamber 2 and the recovery chamber 3 by the bag breaking device 6, the flow-aiding device 7, the recovery device 8, etc., and the bag breaking chamber 2 and the recovery chamber 3 are both closed cavities, so they can effectively isolate dust and prevent indoor dust from spilling to the outside.

[0094] In summary, this embodiment can efficiently complete the feeding operation, reduce manual labor, reduce labor costs, and improve the degree of mechanization of the operation. At the same time, it can avoid the generation of dust during the operation as much as possible, improve the working environment, and reduce the harm to the health of workers.

[0095] like Figure 4 , Figure 7 As shown, Figure 4 Schematic diagram of the specific structure of the bag breaking chamber 2. Figure 7 It is a schematic diagram of the specific structure of the recovery chamber 3.

[0096] In some embodiments, a first avoidance slit 21 is provided on the top surface of the bag breaking chamber 2, and the first avoidance slit 21 is mainly used for the passage of the lifting device 9, so that the lifting device 9 can smoothly enter and exit the bag breaking chamber 2 through the first avoidance slit 21. At the same time, a second avoidance slit 31 is provided on the top surface of the recovery chamber 3, and the second avoidance slit 31 is mainly used for the passage of the lifting device 9, so that the lifting device 9 can smoothly enter and exit the recovery chamber 3 through the second avoidance slit 31. In addition, the bag breaking chamber 2 is flush with the top surface of the recovery chamber 3.

[0097] like Figure 3 As shown, Figure 3 for Figure 2 Top view of the .

[0098] Furthermore, in order to prevent the first avoidance slit 21 and the second avoidance slit 31 from affecting the sealing performance, a folding protective cover 11 is additionally provided in the present embodiment. Specifically, the folding protective cover 11 is arranged on the frame 1, and its two ends are respectively connected to the two ends of the frame 1, and can be elastically telescopically moved by folding to extend or shorten the length, and the bottom surface of the folding protective cover 11 is pressed against the top surfaces of the bag breaking chamber 2 and the recovery chamber 3 to seal the first avoidance slit 21 on the top surface of the bag breaking chamber 2 and the second avoidance slit 31 on the top surface of the recovery chamber 3. At the same time, the lifting device 9 specifically passes through the folding protective cover 11 and is connected to the folding protective cover 11 as a whole. Of course, in order to improve the sealing performance, the position where the lifting device 9 passes through the folding protective cover 11 can also be sealed by components such as sealants and sealing rings to prevent the formation of gaps.

[0099] With such arrangement, when the lifting device 9 moves in and out of the bag breaking chamber 2 and the recovery chamber 3 along the first avoidance slit 21 and the second avoidance slit 31, the local area of ​​the folding protective cover 11 connected to the lifting device 9 will produce elastic folding and telescopic deformation accordingly, which will not hinder the normal operation of the lifting device 9, and can ensure that the folding protective cover 11 as a whole does not move, so that the folding protective cover 11 always maintains pressure on the top surface of the bag breaking chamber 2 and the recovery chamber 3, and the sealing effect on the first avoidance slit 21 and the second avoidance slit 31, so that the bag breaking chamber 2 and the recovery chamber 3 can be completely sealed on the basis of ensuring that the lifting device 9 can smoothly enter and exit the bag breaking chamber 2 and the recovery chamber 3, thereby preventing external dust from occurring during the bag breaking and waste bag unloading operations.

[0100] In a specific embodiment of the foldable protective cover 11, the foldable protective cover 11 is a split structure, mainly including a first cover body 111 and a second cover body 112. The first cover body 111 is connected between one side of the lifting device 9 and one end of the frame 1, and the second cover body 112 is connected between the other side of the lifting device 9 and the other end of the frame 1. For example, the first cover body 111 is located Figure 3 On the left side of the frame 1, the second cover 112 is located Figure 3 The right side of the frame 1 is shown. In this way, the first cover 111 and the second cover 112 are connected as a whole through the lifting device 9 in the middle. Figure 3 When moving in the left direction, the first cover 111 will be compressed and the second cover 112 will be stretched; Figure 3 When moving in the right direction, the first cover body 111 will be stretched and the second cover body 112 will be compressed. Of course, the area where the lifting device 9 itself is located is equivalent to sealing the first avoidance gap 21 or the second avoidance gap 31.

[0101] Considering that if the bag breaking chamber 2 and the recovery chamber 3 are separately arranged on the frame 1, the two are independent of each other, which not only occupies a large area, but also increases the lifting distance of the lifting device 9, which reduces the work efficiency. In view of this, in the present embodiment, the bag breaking chamber 2 and the recovery chamber 3 are connected as a whole, and the two form an integral structure. Specifically, the bag breaking chamber 2 and the recovery chamber 3 are arranged in parallel front and back along the length direction of the frame 1 on the frame 1, and the rear end face of the bag breaking chamber 2 is connected with the front end face of the recovery chamber 3. At the same time, the first avoidance slit 21 on the bag breaking chamber 2 is connected with the second avoidance slit 31 on the recovery chamber 3 to form a slit. Considering that the lifting device 9 also needs to lift the ton bag into the bag breaking chamber 2 and the recovery chamber 3, in order to facilitate the ton bag to enter the room, an outer end door 22 that can be opened and closed is also provided on the front end face of the bag breaking chamber 2. With such arrangement, when the lifting device 9 needs to lift the ton bag into the bag breaking chamber 2 for bag breaking and unloading operations, it is only necessary to open the outer end door 22, and then move the lifting device 9 along the first avoidance gap 21 to enter the bag breaking chamber 2. Of course, after the ton bag enters the bag breaking chamber 2, the outer end door 22 needs to be closed again to ensure the sealing; when the lifting device 9 needs to lift the ton bag after bag breaking into the recycling chamber 3 for waste bag recycling operations, it is only necessary to continue to move the lifting device 9 along the first avoidance gap 21 and the second avoidance gap 31 to enter the recycling chamber 3, without the need to contact the outside world in the middle to cause dust.

[0102] like Figure 5 , Figure 6 As shown, Figure 5 for Figure 4 The front view of Figure 6 for Figure 4 Side view of.

[0103] Furthermore, in order to facilitate the opening and closing control of the outer door 22, the present embodiment is provided with an outer door shaft 23 at the front end of the bag breaking chamber 2, and an outer door driving component 24 is provided on the top surface of the bag breaking chamber 2. Specifically, the side of the outer door 22 is connected to the outer door shaft 23, and the output end of the outer door driving component 24 is connected to the top of the outer door shaft 23, so that the outer door shaft 23 is driven to rotate through the output end of the outer door driving component 24 to realize the rotation opening and closing control. Generally, the outer door driving component 24 can specifically adopt a driving motor and a reducer, or a hydraulic cylinder, a pneumatic cylinder and a connecting rod. At the same time, the outer door 22 can be a single door or two double doors, and the rotational motion states of the two double doors in the latter are synchronously reversed.

[0104] Considering that after the bag breaking chamber 2 and the recycling chamber 3 are connected as one, although the indoor dust can basically not leak to the outside, some of the dust during the bag breaking and unloading operation may enter the recycling chamber 3. Similarly, some of the dust during the waste bag recycling operation may also enter the bag breaking chamber 2, causing mutual influence. In view of this, an inner end door 32 is added in this embodiment. Specifically, the inner end door 32 is arranged between the front end surface of the recycling chamber 3 and the rear end surface of the bag breaking chamber 2. Like the outer end door 22, the inner end door 32 can also be rotated to open and close, so that when the inner end door 32 is closed, the bag breaking chamber 2 and the recycling chamber 3 are temporarily isolated, thereby avoiding the dust from affecting each other during operation.

[0105] Furthermore, in order to facilitate the opening and closing control of the inner end door 32, the present embodiment also has an inner door shaft 33 erected at the rear end of the bag breaking chamber 2, and an inner door driving component 34 is also arranged on the top surface of the bag breaking chamber 2. Specifically, the side of the inner end door 32 is connected to the inner door shaft 33, and the output end of the inner door driving component 34 is connected to the top of the inner door shaft 33, so that the inner door shaft 33 is driven to rotate through the output end of the inner door driving component 34 to realize the rotation opening and closing control. Generally, the inner door driving component 34 can specifically adopt a driving motor and a reducer, or a hydraulic cylinder, a pneumatic cylinder and a connecting rod. At the same time, the inner end door 32 can be a single door or two double doors, and the rotational motion states of the two double doors in the latter are synchronously reversed.

[0106] In addition, considering that the top surfaces of the outer end door 22 and the inner end door 32 are usually not directly placed on the top, but door frames are provided at the front and rear ends of the bag breaking chamber 2, the outer end door 22 and the inner end door 32 are respectively provided in the door frames, and accordingly, the front and rear end surfaces of the first avoidance slit 21 are provided in the door frame, so that although the folding protective cover 11 can cover the top surface of the first avoidance slit 21 to achieve sealing, it is unable to seal the front and rear end surfaces of the first avoidance slit 21, especially the front end surface of the first avoidance slit 21, which may cause dust to leak to the outside. In view of this, a sealing sheet 10 is additionally provided in the present embodiment. Specifically, the sealing sheet 10 is provided at the top of the outer end door 22 and the top of the inner end door 32, wherein the sealing sheet 10 at the top of the outer end door 22 is mainly used to be located exactly on the front end door frame of the bag breaking chamber 2 when closed, so as to cover and seal the front end surface of the first avoidance slit 21. Similarly, the sealing sheet 10 at the top of the inner end door 32 is mainly used to be located on the rear end door frame of the bag breaking chamber 2 when closed, so as to cover and seal the rear end surface of the first avoidance slit 21 (also the front end surface of the second avoidance slit 31). In this way, through the function of the sealing sheet 10, the front and rear end surface holes of the avoidance slits on the bag breaking chamber 2 and the recovery chamber 3 can be supplemented, and the sealing performance can be improved.

[0107] like Fig. 9 As shown, Fig. 9 It is a schematic diagram of the specific structure of the collecting box 5.

[0108] In a specific embodiment of the collection box 5, the collection box 5 mainly includes a box body 51, walking legs 52 and walking rollers 53. Among them, the box body 51 is the main component of the collection box 5, which is mainly used to accommodate a certain amount of recycled waste bags. A through hole or opening is provided on the top of the box body 51 to form a detachable connection with the bottom bag outlet 35 of the recovery chamber 3 and to communicate with each other, such as being connected to each other through a hose or forming a plug-in connection. The walking legs 52 are connected to the bottom of the box body 51 and have a preset height. They are mainly used to support the box body 51, and generally 4 or more can be set at the same time. The walking rollers 53 are arranged at the bottom of each walking leg 52, and generally universal wheels are used.

[0109] Furthermore, considering that the height of the frame 1 is relatively large and the recovery chamber 3 is arranged at a relatively high position on the frame 1, in order to ensure that the collection box 5 can be conveniently connected to the recovery chamber 3, a lifting drive cylinder 54, a lifting bracket 55 and a lifting support seat 56 are additionally provided in this embodiment. Among them, the lifting bracket 55 is mainly used for supporting on the ground, has a preset height, and in a natural state (the piston rod of the lifting drive cylinder 54 is not extended), the bottom of the lifting bracket 55 is flush with the bottom of the roller. The lifting drive cylinder 54 is arranged on the lifting bracket 55 and arranged in the vertical direction, and the top of the piston rod of the lifting drive cylinder 54 is connected to the bottom of the lifting support seat 56, and the top of the lifting support seat 56 is connected to the bottom of the box body 51. With such an arrangement, when it is necessary to connect the top entrance of the box body 51 with the bag outlet 35 of the recovery chamber 3, it is only necessary to start the lifting drive cylinder 54 so that the piston rod of the lifting drive cylinder 54 extends, so that the bottom of the lifting bracket 55 is stably supported on the ground, and at the same time, the lifting support seat 56 is lifted upward, thereby lifting the box body 51 upward, so that the top entrance of the box body 51 and the bag outlet 35 of the recovery chamber 3 are close to each other, and a plug-in connection can be easily formed.

[0110] Considering that when the waste bags collected in the collection box 5 reach a preset amount, centralized transportation processing is required. For this purpose, it is necessary to first release the connection between the collection box 5 and the bottom of the recovery chamber 3. After the collection box 5 transfers the waste bags to the preset position, it is moved to the bottom of the recovery chamber 3 for connection. In order to ensure that the entrance at the top of the collection box 5 can be smoothly docked with the outlet at the bottom of the recovery chamber 3, a positioning roller 12 is added in this embodiment. Specifically, the positioning roller 12 is set on the frame 1, and multiple positioning rollers 12 can be set at the same time. It is mainly used to form abutment with the side wall of the collection box 5, so as to position the moving position of the collection box 5, so that the collection box 5 can accurately stay at the preset position, ensuring that the entrance at the top of the collection box 5 is aligned with the bag outlet 35 at the bottom of the recovery chamber 3. Of course, the entrance at the top of the collection box 5 and the bag outlet 35 at the bottom of the recovery chamber 3 can also be connected through a hose connection, which is not only easy to disassemble and connect, but also allows the collection box 5 to have a large position error.

[0111] Considering that the dust is relatively large when the bag breaking process is performed on the lifting bag in the bag breaking chamber 2 and the waste bag recycling process is performed in the recycling chamber 3, in order to prevent the dust from leaking to the outside due to poor sealing, a dust collector 13 is added in this embodiment. Specifically, two dust collectors 13 are provided, and are respectively arranged on the side walls of the bag breaking chamber 2 and the recycling chamber 3, and are respectively connected to the inside of the bag breaking chamber 2 and the inside of the recycling chamber, so that the dust in the bag breaking chamber 2 and the recycling chamber 3 can be absorbed in real time during the bag breaking process and the waste bag recycling process.

[0112] like Fig.10 As shown, Fig.10 It is a schematic diagram of the specific structure of the bag breaking device 6.

[0113] In a specific embodiment of the bag breaking device 6 , the bag breaking device 6 mainly includes a lifting mechanism 61 and a bag breaking mechanism 62 .

[0114] The lifting mechanism 61 is disposed in the lower material bin 4 , and the output end of the lifting mechanism 61 is connected to the bag breaking mechanism 62 , and is mainly used to drive the bag breaking mechanism 62 to perform vertical lifting movement in the lower material bin 4 .

[0115] The bag breaking mechanism 62 mainly includes a knife frame 621, a breaking cone head 622 and a cutting blade 623. Among them, the knife frame 621 is the main part of the bag breaking mechanism 62, which is mainly used to install the other parts of the bag breaking mechanism 62, and connect the bag breaking mechanism 62 as a whole to the output end of the lifting mechanism 61 through the knife frame 621. The breaking cone head 622 is set at the top position of the knife frame 621, and is generally in the shape of a sharp cone or an arrow, and is mainly used to pierce the bottom surface of the lifting bag, thereby forming a dot-shaped or circular break on the bottom surface of the lifting bag. The cutting blade 623 is also arranged on the tool holder 621, and there are multiple cutting blades 623. Each cutting blade 623 is distributed along the circumferential direction of the tool holder 621, and each cutting blade 623 is arranged obliquely on the tool holder 621 to form a cone-shaped distribution, but the height position on the tool holder 621 is located below the breaking cone head 622, ensuring that when breaking the bag, the breaking cone head 622 always contacts the bottom surface of the lifting bag first and forms a break, and then each cutting blade 623 cuts the bottom surface of the lifting bag, thereby cutting multiple cracks distributed along the circumferential direction outside the break on the bottom surface of the lifting bag.

[0116] With such arrangement, when the lifting bag is lifted to the top of the lower silo 4, the lifting bag is lowered normally. At this time, the lifting mechanism 61 also rises vertically synchronously, and lifts the bag breaking mechanism 62 upward, moving towards the lifting bag; after a short time, the breaking cone head 622 located at the top of the tool holder 621 first contacts the bottom surface of the lifting bag, and pierces the bottom surface of the lifting bag, opening a break in the bottom surface of the lifting bag, and then, the lifting mechanism 61 continues to lift, and each cutting blade 623 then contacts the bottom surface of the lifting bag, and uses the break as a reference to cut multiple circumferentially distributed cracks outside the break.

[0117] When breaking the lifting bag, the present embodiment, on the one hand, utilizes the lifting mechanism 61 to lift and drive the bag breaking mechanism 62, thereby increasing the relative movement speed between the bag breaking mechanism 62 and the lifting bag, thereby increasing the positive impact force between the two; on the other hand, the breaking cone head 622 is firstly utilized to achieve the point-breaking effect on the bottom surface of the lifting bag, thereby forming a break on the bottom surface of the lifting bag, and then the cutting blade 623 is utilized to cut outward along the break. The contact mode between the cutting blade 623 and the lifting bag is improved from the positive line-surface contact to the oblique point-line contact, and the blade pressure is greatly improved, making it easier to cut a crack on the lifting bag, so that a single successful bag breaking can be achieved efficiently and reliably.

[0118] like Fig.11 As shown, Fig.11 It is a schematic diagram of the specific structure of the bag breaking mechanism 62.

[0119] Considering that the tool in the prior art is an integral structure, when part of the blade is damaged or notched, the entire tool needs to be disassembled and replaced, resulting in high maintenance costs. In view of this, in a specific embodiment of the bag breaking mechanism 62, the bag breaking mechanism 62 also includes a mounting column 624. Specifically, the mounting column 624 is erected at the center of the tool holder 621 and has a preset height, and the broken cone head 622 is specifically arranged at the top position of the mounting column 624, and a detachable connection is formed between the broken cone head 622 and the mounting column 624. For example, the bottom of the broken cone head 622 forms a threaded connection, a card plug connection, etc. with the top of the mounting column 624. In this way, when the blade of the broken cone head 622 is damaged, it is only necessary to remove the broken cone head 622 from the mounting column 624 and reinstall a new broken cone head 622, without replacing the entire bag breaking mechanism 62.

[0120] Similarly, if the blade of the cutting blade 623 is damaged, it also needs to be replaced. In view of this, an installation baffle 625 is also provided in this embodiment. Specifically, the installation baffle 625 is connected between the installation column 624 and the tool holder 621, and multiple pieces are provided at the same time, and each installation baffle 625 is evenly or unevenly distributed along the circumferential direction of the installation column 624. Each installation baffle 625 is in the shape of a triangle or a trapezoid as a whole, such as a right triangle, and one of the right-angled sides is connected to the top surface of the tool holder 621, and the other right-angled side is connected to the installation column 624, and the cutting blade 623 is arranged on the hypotenuse, and multiple cutting blades 623 form a cone. At the same time, each cutting blade 623 forms a detachable connection with each installation baffle 625, such as a threaded connection, a snap-on connection, etc. With such arrangement, when the blade of a cutting blade 623 is damaged, it is only necessary to remove the cutting blade 623 from the corresponding mounting baffle 625 and then reinstall a new cutting blade 623, without having to replace all the cutting blades 623. Generally, there are 8 mounting baffles 625 evenly distributed along the circumference of the mounting column 624, and correspondingly, there are 8 cutting blades 623 evenly distributed on the blade holder 621.

[0121] In order to improve the installation stability of the cutting blade 623 on the mounting baffle 625, a clamping plate 626 is added in this embodiment. Specifically, the clamping plate 626 is arranged on the side of the mounting baffle 625 and forms a detachable connection with the mounting baffle 625. At the same time, the cutting blade 623 is closely arranged on the side of the mounting baffle 625, which is equivalent to the mounting baffle 625 and the clamping plate 626 clamping each other, thereby clamping and fixing the cutting blade 623.

[0122] like Fig.12 As shown, Fig.12 It is a schematic diagram of the specific structure of the flow-aiding device 7.

[0123] In a specific embodiment of the flow-aiding device 7, the flow-aiding device 7 mainly includes a flow-aiding mounting plate 71, a transverse vibration mechanism 72 and a vertical vibration mechanism 73. The flow-aiding mounting plate 71 is fixedly mounted on the side wall of the bag-breaking chamber 2, and the transverse vibration mechanism 72 is mounted on the flow-aiding mounting plate 71, and is mainly used to slap the side wall of the hoisting bag in the horizontal direction, thereby forming a vibration effect in the horizontal direction on the hoisting bag, that is, shaking left and right; the vertical vibration mechanism 73 is also mounted on the flow-aiding mounting plate 71, and is mainly used to slap the bottom surface of the hoisting bag in the vertical direction, thereby forming a vibration effect in the vertical direction on the hoisting bag, that is, shaking up and down.

[0124] like Fig.13 As shown, Fig.13 for Fig.12 Top view of the local structure.

[0125] In a specific embodiment of the lateral vibration mechanism 72, the lateral vibration mechanism 72 mainly includes a first drive cylinder 721 and a flapping plate 722. The first drive cylinder 721 is arranged on the flow-aiding mounting plate 71, and the cylinder body is generally arranged on the outer surface of the flow-aiding mounting plate 71, while the piston rod passes through the flow-aiding mounting plate 71 and extends to the inner side of the flow-aiding mounting plate 71 and faces the lifting bag. The flapping plate 722 is arranged in the inner area of ​​the flow-aiding mounting plate 71 and is connected to the output end of the first drive cylinder 721, such as being connected to the end of the piston rod of the first drive cylinder 721. When the piston rod of the first driving cylinder 721 extends inward, it drives the flapping plate 722 to move synchronously toward the side wall of the lifting bag until the front end surface (or inner surface) of the flapping plate 722 abuts against the side wall of the lifting bag, completing one flapping operation; thereafter, the piston rod of the first driving cylinder 721 retracts outward again, driving the flapping plate 722 to move synchronously toward the direction away from the side wall of the lifting bag, until the flapping plate 722 maintains a certain distance from the lifting bag, and the piston rod of the first driving cylinder 721 extends inward again, and this is repeated to complete multiple flapping operations on the side wall of the lifting bag.

[0126] Generally, the linear extension direction of the piston rod of the first driving cylinder 721 is horizontal, that is, the width direction of the bag breaking chamber 2 or the spacing direction of the inner walls on both sides of the bag breaking chamber 2.

[0127] In a specific embodiment of the vertical vibration mechanism 73, the vertical vibration mechanism 73 mainly includes a hinge support 731, a second drive cylinder 732, a connecting seat 733, a support rod 734, a rotating sleeve 735 and a beating roller 736. Among them, the hinge support 731 is arranged on the flow-aiding mounting plate 71, specifically on the inner side surface of the flow-aiding mounting plate 71, and generally two are arranged at the same time, and are respectively located at the two ends of the length direction of the flow-aiding mounting plate 71. The connecting seat 733 is also arranged on the flow-aiding mounting plate 71 (or the inner wall of the bag breaking chamber 2), specifically on the inner side surface of the flow-aiding mounting plate 71, and is generally located below the hinge support 731, and two can be arranged at the same time, and are respectively located at the two ends of the length direction of the flow-aiding mounting plate 71. The support rod 734 is arranged on the connecting seat 733, and can generally be connected between the two connecting seats 733, and remain parallel to the length direction of the flow-aiding mounting plate 71. The rotating sleeve 735 is sleeved on the support rod 734 and forms a rotational connection with the support rod 734, and can rotate on the support rod 734. One end of the second drive cylinder 732 is connected to the hinge support 731, that is, a rotational connection is formed, and the other end of the second drive cylinder 732 is connected to the outer wall of the rotating sleeve 735 and a rotational connection is formed. Since two hinge supports 731 are generally provided at the same time, two second drive cylinders 732 can also be provided accordingly, and are respectively connected to the corresponding hinge supports 731, and the other ends of the two second drive cylinders 732 are respectively connected to the axial two end positions on the outer wall of the rotating sleeve 735. The beating roller 736 is connected to the outer wall of the rotating sleeve 735, is generally cylindrical, and remains parallel to the support rod 734, and is located at the bottom of the hoisting bag as a whole.

[0128] With such arrangement, when the piston rod of the second driving cylinder 732 is extended or retracted, a pushing and pulling force will be formed on the outer wall of the rotating sleeve 735, thereby forming a rotational torque on the rotating sleeve 735, driving the rotating sleeve 735 to rotate clockwise or counterclockwise, and finally driving the flapping roller 736 and the rotating sleeve 735 to perform synchronous rotational motion; at the same time, when the piston rod of the second driving cylinder 732 performs repeated telescopic motion, the flapping roller 736 will synchronously perform a reciprocating swinging motion at a certain angle, and when the flapping roller 736 swings to the top of the track, it will abut against the bottom surface of the lifting bag, thereby forming a flapping effect on the bottom surface of the lifting bag, thereby causing the lifting bag to produce a vibration effect of shaking up and down.

[0129] like Fig.14 As shown, Fig.14 It is a schematic diagram of the specific structure of the outward extension plate 737 and the inward extension plate 738.

[0130] Furthermore, in order to facilitate the connection between the piston rod of the second drive cylinder 732 and the rotating sleeve 735, and the connection between the flapping roller 736 and the rotating sleeve 735, this embodiment adds an outward extension plate 737 and an inward extension plate 738 in the vertical vibration mechanism 73. Among them, the outward extension plate 737 is connected to the outer side wall of the rotating sleeve 735 and extends in the direction toward the flow-aiding mounting plate 71, so that the end of the piston rod of the first drive cylinder 721 is rotatably connected to the outward extension plate 737 through components such as a pin. The inward extension plate 738 is connected to the inner side wall of the rotating sleeve 735 and extends in the direction away from the flow-aiding mounting plate 71, so that the flapping tube is connected to the extended end of the inward extension plate 738.

[0131] Generally, the vertical vibration mechanism 73 and the horizontal vibration mechanism 72 can be operated separately or simultaneously. Obviously, the latter has a stronger vibration effect and a better auxiliary feeding effect.

[0132] like Fig.15 As shown, Fig.15 It is a schematic diagram of the specific structure of the recovery device 8.

[0133] In a specific embodiment of the recovery device 8 , the recovery device 8 mainly includes a compression mechanism 81 and an extrusion mechanism 82 .

[0134] The compression mechanism 81 is disposed on the side wall of the recovery chamber 3, and is mainly used to gradually flatten the waste bag from the top until the waste bag is compressed as a whole to the bag outlet 35 at the bottom of the recovery chamber 3. At this time, if the waste bag has a regular shape matching the shape of the bag outlet 35, it may fall directly out of the bag outlet 35. However, the waste bag usually still presents an irregular shape even after compression, but its height is reduced and its volume is reduced.

[0135] The extrusion mechanism 82 is also arranged on the side wall of the recovery chamber 3, and is mainly used to punch the top of the waste bag that is still stuck at the bag outlet 35 after compression, so as to squeeze the waste bag out of the bag outlet 35 and drop it into the waste collection vehicle under the recovery chamber 3, thereby realizing the waste bag recovery operation.

[0136] With such arrangement, when the waste bag is hoisted into the recovery chamber 3, the top of the waste bag is first compressed by the compression mechanism 81 to flatten the waste bag as a whole and reduce its volume, and then pressed to the bag outlet 35, and then the compressed waste bag is punched by the extrusion mechanism 82 to squeeze the waste bag out of the bag outlet 35, thereby realizing the waste bag recovery operation.

[0137] In order to improve the efficiency of punching and extruding the waste bag, in this embodiment, two sets of extrusion mechanisms 82 are provided at the same time, and the two sets of extrusion mechanisms 82 are respectively provided on the side walls of the recycling chamber 3, so that the top left and right sides of the waste bag can be impacted at the same time. Correspondingly, only one compression mechanism 81 is required, and it is provided on the side wall of the recycling chamber 3 adjacent to the side wall where the extrusion mechanism 82 is located. For example, the recycling chamber 3 is usually rectangular, and the two sets of extrusion mechanisms 82 are respectively provided on the side walls of the recycling chamber 3, and the compression mechanism 81 is provided on the front side or rear side wall of the recycling chamber 3.

[0138] like Fig.16 As shown, Fig.16 It is a schematic diagram of the specific structure of the compression mechanism 81.

[0139] In a specific embodiment of the compression mechanism 81, the compression mechanism 81 mainly includes a compression mounting seat 811, a compression drive cylinder 812 and a compression rod group 813. The compression mounting seat 811 is arranged on the side wall of the recovery chamber 3, can be connected to the side wall of the recovery chamber 3 as a whole, and is connected to the side wall of the recovery chamber 3 in a convex shape. The compression drive cylinder 812 is arranged on the compression mounting seat 811, and the compression rod group 813 is also arranged on the compression mounting seat 811, and forms a rotation connection with the compression mounting seat 811, and can rotate relative to the compression mounting seat 811. At the same time, the output end of the compression drive cylinder 812 is connected to the compression rod group 813, which is mainly used to drive the compression rod group 813 to rotate and press the top of the waste bag, so as to flatten the waste bag until the compression is completed. For example, the end of the piston rod of the compression drive cylinder 812 is connected to the compression rod group 813. Generally, the compression rod group 813 is located above the recovery chamber 3 as a whole, and the rotation trajectory range of the compression rod group 813 is located above the top of the waste bag. With such arrangement, when the compression drive cylinder 812 operates, the piston rod extends or retracts, thereby driving the compression rod set 813 to rotate clockwise or counterclockwise, thereby causing the compression rod set 813 to press the top of the waste bag or detach from the top of the waste bag.

[0140] In a specific embodiment of the compression drive cylinder 812, the compression drive cylinder 812 is specifically arranged on the outside of the compression mounting seat 811, or on the outer wall of the recovery chamber 3, and the compression rod group 813 is specifically arranged on the inside of the compression mounting seat 811 and located in the recovery chamber 3. In order to facilitate the connection between the output end of the compression drive cylinder 812 and the compression rod group 813, in this embodiment, the output end of the compression drive cylinder 812 passes through the compression mounting seat 811 from the outside and extends to the inside thereof, thereby connecting with the compression rod group 813.

[0141] In a specific embodiment of the compression rod group 813, the compression rod group 813 mainly includes a compression rotating shaft 8131 and a lower pressure rod frame 8132. The compression rotating shaft 8131 is inserted on the compression mounting seat 811, such as inserted between the side walls of the compression mounting seat 811, and forms a rotation connection with the compression mounting seat 811, has a rotational freedom, and can rotate relative to the compression mounting seat 811. At the same time, one end of the compression rotating shaft 8131 extends out of the side wall of the compression mounting seat 811 to be connected to the output end of the compression drive cylinder 812. One end of the lower pressure rod frame 8132 is connected to the compression rotating shaft 8131, and the other end extends a preset length along a preset direction, and can rotate synchronously with the compression rotating shaft 8131, and is mainly used to compress the top of the waste bag. With such arrangement, when the piston rod of the compression drive cylinder 812 is extended or retracted, it can drive the compression rotating shaft 8131 to rotate synchronously clockwise or counterclockwise, thereby driving the lower pressure rod frame 8132 to swing up and down.

[0142] Generally, the lower pressure rod frame 8132 is specifically a plurality of truss structures connected horizontally and vertically to cover a larger area of ​​the top of the waste bag and improve the compression efficiency.

[0143] Furthermore, in order to facilitate the dynamic connection between the piston rod of the compression drive cylinder 812 and the extended end of the compression rotating shaft 8131, a compression swing rod 814 is added in this embodiment. Specifically, one end of the compression swing rod 814 is rotationally connected with the end of the piston rod of the compression drive cylinder 812, such as being connected by a pin, and at the same time, the other end of the compression swing rod 814 is connected to the extended end of the compression rotating shaft 8131. In this way, when the piston rod of the compression drive cylinder 812 is extended or retracted, a pulling force or a thrust force will be applied to the end of the compression swing rod 814, thereby forming a rotation torque on the compression rotating shaft 8131 through the compression swing rod 814, thereby driving the compression rotating shaft 8131 to rotate. Of course, in order to avoid motion interference, the cylinder body of the compression drive cylinder 812 is also rotationally connected with the compression mounting seat 811 or the outer wall of the recovery chamber 3.

[0144] Of course, the compression mechanism 81 is not limited to the above-mentioned structure. Other structures, such as using a driving motor in combination with a reducer to drive the compression rotating shaft 8131 to rotate, are also feasible.

[0145] like Fig.17 As shown, Fig.17 It is a schematic diagram of the specific structure of the extrusion mechanism 82.

[0146] In a specific embodiment of the extrusion mechanism 82, the extrusion mechanism 82 mainly includes a stamping mounting seat 821, a stamping drive cylinder 822 and a stamping rod group 823. Among them, the stamping mounting seat 821 is arranged on the side wall of the recovery chamber 3, can be connected to the side wall of the recovery chamber 3 as a whole, and is protrudingly connected to the side wall of the recovery chamber 3 in a convex shape. The stamping drive cylinder 822 is arranged on the stamping mounting seat 821, and the compression rod group 813 is also arranged on the stamping mounting seat 821, and forms a rotation connection with the stamping mounting seat 821, and can rotate relative to the stamping mounting seat 821. At the same time, the output end of the stamping drive cylinder 822 is connected to the stamping rod group 823, which is mainly used to drive the stamping rod group 823 to rotate, and during the rotation process, a stamping effect is formed on the top of the waste bag, so that the waste bag is squeezed and falls out of the bag outlet 35. For example, the end of the piston rod of the stamping drive cylinder 822 is connected to the stamping rod group 823. Generally, the punching rod group 823 is located in the middle or lower part of the recovery chamber 3, and the rotation track range of the punching rod group 823 is located above the top of the waste bag, wherein the lowest position of the track can reach the bottom of the bag outlet 35. In this way, when the punching drive cylinder 822 is running, the piston rod extends or retracts, thereby driving the punching rod group 823 to rotate clockwise or counterclockwise, so that the punching rod group 823 forms a punching effect on the top of the waste bag during the rotation process.

[0147] In a specific embodiment of the punching drive cylinder 822, the punching drive cylinder 822 is specifically arranged on the outside of the punching mounting seat 821, or on the outer wall of the recovery chamber 3, and the punching rod group 823 is specifically arranged on the inside of the punching mounting seat 821 and located in the recovery chamber 3. In order to facilitate the connection between the output end of the punching drive cylinder 822 and the punching rod group 823, in this embodiment, the output end of the punching drive cylinder 822 passes through the punching mounting seat 821 from the outside and extends to the inside thereof, thereby connecting with the punching rod group 823.

[0148] In a specific embodiment of the punching rod group 823 , the punching rod group 823 mainly includes a punching rotating shaft 8231 and a punching rod frame 8232 .

[0149] The punching rotating shaft 8231 is inserted on the punching mounting seat 821, for example, between the side walls of the punching mounting seat 821, and is rotatably connected with the punching mounting seat 821, has a rotational freedom, and can rotate relative to the punching mounting seat 821. At the same time, one end of the punching rotating shaft 8231 extends out of the side wall of the punching mounting seat 821 to be connected to the output end of the punching driving cylinder 822.

[0150] The punching rod frame 8232 can be an integral structure, one end of which is connected to the punching rotating shaft 8231, and the other end of which is L-shaped and extends downward by a preset length, and can rotate synchronously with the punching rotating shaft 8231, and is mainly used to punch the top of the waste bag. In this way, when the piston rod of the punching drive cylinder 822 is extended or retracted, it can drive the punching rotating shaft 8231 to rotate synchronously clockwise or counterclockwise, and then drive the punching rod frame 8232 to swing up and down, so as to hit the top of the waste bag obliquely during the downward swinging process, thereby forming a punching effect on the waste bag.

[0151] Of course, the punching rod frame 8232 can also be a split structure, specifically including a horizontal extension rod and a vertical punching rod. Among them, one end of the horizontal extension rod is connected to the punching rotating shaft 8231, and can rotate synchronously with it, while the other end of the horizontal extension rod is connected to the top of the vertical punching rod. At the same time, the vertical punching rod extends downward as a whole and maintains a vertical state. In this way, when the piston rod of the punching drive cylinder 822 extends or retracts, it can drive the punching rotating shaft 8231 to rotate synchronously clockwise or counterclockwise, thereby driving the horizontal extension rod in the punching rod frame 8232 to swing up and down, and finally drive the vertical punching rod to perform vertical lifting movement through the connecting rod transmission characteristics, so that when the vertical punching rod vertically descends, it will positively hit the top of the waste bag, forming a punching effect on the waste bag.

[0152] Further, in order to facilitate the power connection between the piston rod of the stamping drive cylinder 822 and the extended end of the stamping rotating shaft 8231, a stamping swing rod 824 is additionally provided in this embodiment. Specifically, one end of the stamping swing rod 824 is rotatably connected with the end of the piston rod of the stamping drive cylinder 822, such as being connected by a pin, and at the same time, the other end of the stamping swing rod 824 is connected to the extended end of the stamping rotating shaft 8231. In this way, when the piston rod of the stamping drive cylinder 822 is extended or retracted, a pulling force or a thrust force is applied to the end of the stamping swing rod 824, thereby forming a rotational torque on the stamping rotating shaft 8231 through the stamping swing rod 824, and then driving the stamping rotating shaft 8231 to perform a rotational motion. Of course, in order to avoid motion interference, the cylinder body of the stamping drive cylinder 822 is also rotatably connected with the stamping mounting seat 821 or the outer wall of the recovery chamber 3.

[0153] Of course, the extrusion mechanism 82 is not limited to the above structure, and other structures such as using a driving motor combined with a reducer to drive the stamping rotating shaft 8231 to rotate are also feasible.

[0154] like Fig.18 As shown, Fig.18 It is a schematic diagram of the local structure of the lifting device 9.

[0155] In a specific embodiment of the lifting device 9 , the lifting device 9 mainly includes a three-dimensional motion mechanism 91 , a lifting bracket 92 and a hook assembly 93 .

[0156] Among them, the three-dimensional motion mechanism 91 mainly adopts an XYZ three-axis motion mechanism and the like.

[0157] The hanging bracket 92 is connected to the frame 1, and the hook assembly 93 is connected to the bottom of the hanging bracket 92. At least two hook assemblies 93 are provided and are respectively located at the two sides of the bottom of the hanging bracket 92. They are also distributed opposite to each other in the circumferential direction of the hanging bracket 92, corresponding to the side hanging belt b on the hanging bag a. At the same time, the hook assembly 93 is connected to the hanging bracket 92 in a rotating manner and can be turned inward or outward. The hook assembly 93 is mainly used to pass through the gap space between the side hanging belt b and the outer side wall of the hanging bag a from the bottom, so that the side hanging belt b is hung on the hook assembly 93.

[0158] With such a configuration, when the lifting bag a is to be lifted, the height of the lifting bracket 92 is first lowered on the frame 1 to a suitable height above the lifting bag a. Specifically, the hook assembly 93 at the bottom of the lifting bracket 92 is exactly located below the side hanging belt b on the lifting bag a. Then the hook assembly 93 is slightly flipped inwards so that the hook assembly 93 slightly abuts against the side wall of the lifting bag a, and then passes through the gap between the side hanging belt b and the outer wall of the lifting bag a from below, so that the side hanging belt b slides into the hook assembly 93 to achieve a hanging connection. After that, the lifting bag a can be lifted to the target position through the horizontal movement and / or lifting movement of the lifting bracket 92, and then the hook assembly 93 is flipped outwards so that the side hanging belt slides out of the hook assembly 93 and is disconnected from the hanging connection, so that the lifting bag a can automatically fall under the action of gravity.

[0159] In a specific embodiment of the hook assembly 93, the hook assembly 93 mainly includes a lifting connecting rod 931, a lifting driving plate 932, a gripping driving cylinder 933 and a hook 934. Among them, the lifting connecting rod 931 is connected to the bottom of the lifting bracket 92, and generally extends a preset length vertically downward. The lifting driving plate 932 is connected to the bottom end of the lifting connecting rod 931, and forms a rotation connection with the lifting connecting rod 931, such as being connected or hinged by a pin shaft. The gripping driving cylinder 933 is connected to the bottom of the lifting bracket 92, and the output end of the gripping driving cylinder 933 is connected to the lifting driving plate 932, which is mainly used to drive the lifting driving plate 932 to rotate inward or outward relative to the lifting connecting rod 931 (i.e. swing) through the linear motion of the piston rod of the gripping driving cylinder 933. The hook 934 is arranged on the hoisting driving plate 932, generally at the bottom of the hoisting driving plate 932, and extends inwardly, and is mainly used for hanging the side hanging belt b.

[0160] In this way, when the piston rod of the clamping drive cylinder 933 is extended, it will push the lifting drive plate 932 to rotate outward, thereby driving the hook 934 away from the lifting bag a; conversely, when the piston rod of the clamping drive cylinder 933 is retracted, it will push the lifting drive plate 932 to rotate inward, thereby driving the hook 934 to approach the lifting bag a, until it abuts against the outer wall of the lifting bag a and passes through the gap between the side hanging belt b and the outer wall of the lifting bag a from below, thereby realizing the hanging connection of the side hanging belt b on the hook 934.

[0161] In a specific embodiment of the hoisting drive plate 932, the hoisting drive plate 932 is specifically an L-shaped plate, that is, it includes two mutually perpendicular sides, and the piston rod of the clamping drive cylinder 933 is connected to one side of the hoisting drive plate 932, and the hook 934 is specifically arranged on the other side of the hoisting drive plate 932. In this way, the linear motion of the piston rod of the clamping drive cylinder 933 can be easily converted into the rotational motion of the hoisting drive plate 932. Of course, the hoisting drive plate 932 is not limited to the L-shaped plate structure, and other structures such as triangular structure, wedge structure, etc., or a linear structure but connected to the piston rod of the clamping drive cylinder 933 through other transmission mechanisms that can change the transmission direction, etc., are also feasible.

[0162] like Fig.19 As shown, Fig.19 It is a schematic diagram of the specific structure of the lifting bag.

[0163] In a specific embodiment of the hook 934, in order to facilitate the side hanging belt b to slide smoothly into the hook 934 to form a stable hanging connection, in this embodiment, the top surface of the hook 934 is specifically an inclined surface. Specifically, the low point of the inclined surface is located at the root connected to the hanging link 931, and the high point is located at the outer end, facing the hanging bag a, and the slope is generally between 15° and 45°. In this way, when the outer end of the hook 934 abuts against the outer wall of the hanging bag a and just penetrates the gap between the side hanging belt b and the hanging bag a, the side hanging belt b can slide along the inclined surface of the hook 934 to the root of the hook 934 under the action of its own weight to achieve stable hanging.

[0164] In order to prevent the side hanging belt b from accidentally detaching from the hook 934 during the lifting process, in this embodiment, a lock hole is opened on the top surface of the hook 934, and the lock hole can be a through hole or a blind hole. At the same time, a locking drive cylinder 935 is provided on the outer side of the lifting drive plate 932, and a lock pin 936 is provided on the inner side of the lifting drive plate 932. Specifically, the lock pin 936 is slidably arranged on the inner side of the lifting drive plate 932, and the top of the lock pin 936 passes through the plate body of the lifting drive plate 932 and is connected to the output end (i.e., piston rod) of the locking drive cylinder 935. The output end of the locking drive cylinder 935 can move linearly along the extension direction (such as the length direction) of the lifting drive plate 932, so that the lock pin 936 can be driven by the locking drive cylinder 935 to move synchronously on the lifting drive plate 932, so that the lock pin 936 can move linearly toward the hook 934 until the bottom end of the lock pin 936 is inserted into the lock hole on the hook 934 to achieve locking. Of course, a through hole or a slit can also be provided on the hoisting drive plate 932 to avoid the top of the locking pin 936. With such a configuration, after the side hanging belt b slides into the root position of the hook 934 to form a hanging connection, the locking drive cylinder 935 can drive the locking pin 936 to move toward the hook 934 (such as vertical downward movement) until the bottom end of the locking pin 936 is inserted into the locking hole on the hook 934, so that the locking pin 936, the hook 934, and the hoisting drive plate 932 form a temporary closed space together, and the side hanging belt b is locked in the closed space, thereby preventing the side hanging belt b from accidentally detaching from the hook 934 during the hoisting process.
