Description

Technical Field

[0001] The present invention relates to the technical field of domestic waste treatment equipment, and in particular to a bag tearing machine and a use method thereof. Background Art

[0002] Most of the domestic waste generated by residents is first put into garbage bags and then sent to designated garbage collection points. This practice is of great significance for improving the efficiency of garbage disposal and promoting resource recycling. However, in the garbage disposal process, the bagged domestic waste must first be torn and removed from the bag before further comprehensive sorting. This step is crucial for subsequent garbage disposal. Therefore, as a key equipment for the preliminary treatment of bagged garbage, the performance and efficiency of the bag tearing machine directly affect the smoothness of the entire garbage disposal process.

[0003] In the prior art, there are many types of bag breaking machines to meet this demand. For example, Chinese patent publication number CN114408313A discloses a garbage disposal system and its supporting garbage bag breaking machine, which adopts a hydraulically driven single-axis design. However, this design has obvious defects, that is, the bag breaking roller is prone to generate large impact vibration during the forward and reverse rotation process, which not only affects the stability and service life of the equipment, but also may cause noise pollution to the surrounding environment.

[0004] For another example, a Chinese patent with publication number CN 113578477 A introduces a single-axis bag breaker that uses a cam structure guide groove and an arc-shaped groove to achieve the extension and retraction of the crushing knife. Although this design improves the bag breaking efficiency to a certain extent, it also has the problem of inconvenient tool replacement and maintenance. What is more serious is that when foreign matter is mixed in the garbage bag, these foreign matter can easily enter the inside of the crushing roller, interfere with the extension and retraction action of the crushing knife, and even cause the equipment to jam, affecting the continuity and efficiency of garbage treatment. In addition, the clamping plate adjustment in the clamping device of the bag breaker is mechanical, which is cumbersome, time-consuming and labor-intensive to operate, and is not conducive to the rapid response and flexible adjustment of the equipment.

[0005] In summary, the bag tearing machine in the prior art has deficiencies in performance, stability and ease of use to varying degrees, and it is difficult to meet the growing needs and standards for domestic waste treatment. Therefore, it is urgent to develop a bag tearing machine and a method of using the same to solve the problems in the prior art and improve the efficiency and quality of waste treatment.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0050] The following is based on the attached Figure 1 To Attachment Fig.10 The invention discloses a bag tearing machine and a method for using the bag tearing machine.

[0051] Specifically, refer to Figure 1 As shown, in this embodiment, the bag tearing machine mainly includes a conveying device 100, a storage bin 300, a tearing device 200, a hydraulic device 500 and a discharge chute device 400. Among them, the conveying device 100 is used to input materials (such as garbage bags and recyclables) into the tearing device 200, and the storage bin 300 is used to facilitate the stacking and collection of materials in the conveying device 100. The tearing device 200 is used to tear the material to remove the bag, thereby tearing the material, especially the bag structure such as garbage bags. The hydraulic device 500 is used to provide power to some driving parts in the tearing device 200, so as to realize the tearing and removing of the bag with a preset pressure. The torn fragments and various garbage are collected by the discharge chute device 400 to facilitate the input into the subsequent garbage disposal equipment.

[0052] Specifically, Figure 2 , Figure 3 As shown, the tearing device 200 includes a rotor assembly, a fixed knife assembly and a scraper assembly. The rotor assembly includes a rotor roller 203 and a plurality of first knives 209, which are detachably arranged on the outer circumference of the rotor roller 203, and the rotor roller 203 has the ability to rotate in the clockwise direction and the counterclockwise direction, so that it can selectively rotate in the clockwise direction or the counterclockwise direction.

[0053] The fixed knife assembly includes a fixed knife support 204 and a plurality of second knives 210. The plurality of second knives 210 are arranged on the fixed knife support 204 and are detachably arranged in a direction parallel to the axial direction of the rotor roller 203, thereby facilitating the disassembly and maintenance of the second knives 210. The hydraulic device 500 can drive the second knives 210 to move in a direction close to the rotor roller 203 until the second knives 210 extend into the space between two adjacent first knives 209 to form a small and curved gap. In this embodiment, as Figure 2 As shown, when the rotor roller 203 rotates continuously in the clockwise direction, the first cutter 209 can carry the material to move. When the material passes through the gap, the bag structure can be torn by the first cutter 209 and the second cutter 210, thereby releasing the recyclables in the bag structure and tearing the bag. Compared with the continuous alternating forward and reverse rotation in the prior art, the impact vibration generated when the bag is broken can be greatly reduced, and the noise pollution to the surrounding environment can be reduced.

[0054] In addition, the hydraulic device 500 can also drive the second cutter 210 to move in a direction away from the rotor roller 203, so that the second cutter 210 can leave between the two adjacent first cutters 209 to form a passage space with a larger spacing. The passage space can allow materials with a larger volume to pass through, so as to facilitate the withdrawal and anti-jamming. For example, in the process of tearing and bagging, when encountering a larger volume or harder material that is difficult to tear, first move the second cutter 210 so that the second cutter 210 moves from between the adjacent first cutters 209 to outside the adjacent first cutters 209 to form the above-mentioned passage space, and then reverse the rotation direction of the rotor roller 203, so that the material that was originally unable to pass through the gap or stuck in the gap can be withdrawn from the feed port position of the tearing device 200 to avoid continuous jamming. Compared with the operation of stopping the machine for disassembly and then manually removing the material in the prior art, it can greatly facilitate the normal use and maintenance of the bag tearing machine and reduce the loss of the bag tearing machine during use.

[0055] The scraper assembly includes a scraper support 205 and a plurality of third cutters 214, which are arranged on the scraper support 205 and are detachably arranged in a direction parallel to the axial direction of the rotor roller 203, thereby facilitating the disassembly and maintenance of the third cutters 214. The hydraulic device 500 can drive the second cutter 210 to reciprocate in the direction of approaching and moving away from the rotor roller 203 until the third cutter 214 extends into the space between two adjacent first cutters 209 to achieve scraping and cleaning. For example, in this embodiment, the second cutter 210 is lifted and lowered in a vertical direction, and can extend into the space between two adjacent first cutters 209 during the movement of the second cutter 210, thereby ejecting and scraping the material stuck between the two adjacent first cutters 209. By rotating the rotor roller 203 clockwise or counterclockwise, the outer peripheral surface of the rotor roller 203 can be scraped and cleaned comprehensively.

[0056] The bag tearing machine is equipped with a rotor assembly, a fixed knife assembly and a scraper assembly, which can respectively realize tearing and removing bags, returning materials to prevent jamming, and scraping and cleaning through the cooperation of the three. It has excellent garbage disposal performance, high stability and ease of use, thereby realizing continuous and efficient garbage disposal and meeting the growing needs and standards for garbage disposal.

[0057] Preferably, if Figure 3 , Figure 4 As shown, in this embodiment, the rotor roller 203 is a roller in the shape of a regular octagon welded from thick plates, that is, the outer circumference of the rotor roller 203 is composed of eight planes. A plurality of first cutters 209 are installed on each plane, and the plurality of first cutters 209 on the same plane are arranged equidistantly, and the first cutters 209 on two adjacent planes are staggered. Exemplarily, in two adjacent planes, n first cutters 209 are arranged on one plane, and n+1 first cutters 209 are arranged on the other plane, and the first cutters 209 on each plane are symmetrically arranged about the center of the plane, so that the first cutters 209 on two adjacent planes are staggered.

[0058] More preferably, if Figure 4 As shown, the first cutter 209 adopts an integrated structure formed by welding a first cutter seat 209A and a first cutter body 209B, which can withstand greater pressure and achieve a better tearing effect. The first cutter seat 209A is detachably mounted on the outer circumference of the rotor roller 203 through a hexagon socket screw 209C. When the first cutter body 209B is worn, it only needs to be replaced as a whole, which greatly improves the convenience of installation and maintenance.

[0059] In this embodiment, continue to refer to Figure 2 , Figure 3As shown, the tearing device 200 also includes a frame assembly and a drive assembly 207. The frame assembly is fixedly arranged, and the drive assembly 207, the rotor assembly, the fixed knife assembly and the scraper assembly are all installed on the frame assembly. The drive assembly 207 adopts a combined drive structure of a variable frequency motor and a reducer, and the variable frequency motor is connected to the reducer through a roller chain coupling 208. The variable frequency motor has the function of adjusting the rotation direction and the rotation power, the reducer can adjust the torque of the rotor roller 203, and the roller chain coupling 208 can protect the variable frequency motor and the reducer. Exemplarily, in this embodiment, when the variable frequency motor drives the rotor roller 203 to rotate clockwise, the operation of tearing and removing the bag (scraping and cleaning can also be performed) can be realized, and when the variable frequency motor drives the rotor roller 203 to rotate counterclockwise, the operation of withdrawing material and preventing jamming (scraping and cleaning can also be performed) can be realized.

[0060] like Figure 3 As shown, in this embodiment, the tearing device 200 also includes a first lifting assembly 212 and a second lifting assembly 213. The first lifting assembly 212 is used to control the distance between the second tool 210 and the rotor roller 203, and the second lifting assembly 213 is used to control the distance between the third tool 214 and the rotor roller 203.

[0061] Specifically, the frame assembly includes a first support frame 201, an upper frame 202 and a front side frame 206, and the first support frame 201 is used to fix and support the upper frame 202, the front side frame 206, the rotor assembly and the driving assembly 207. The fixed knife assembly is installed on the upper frame 202 and is located above the rotor assembly. The upper frame 202 is provided with a guide rail, and the fixed knife bracket 204 is slidably installed on the guide rail, and can approach and move away from the rotor roller 203 along the guide rail under the drive of the first lifting assembly 212. Optionally, in this embodiment, the first lifting assembly 212 includes a gear rack structure and is driven by the above-mentioned hydraulic device 500, so that the second tool 210 cooperates with the first tool 209 to apply a constant preset pressure to the material to achieve stable tearing and bag removal.

[0062] Similar to the first cutter 209, the second cutter 210 is also detachably installed by bolt fixing, so as to facilitate maintenance and replacement. Specifically, the fixed cutter bracket 204 is connected with a plurality of second cutters 210, each of which includes a mounting plate 210A, a second cutter seat 210B and a second cutter body 210C. The second cutter body 210C adopts a serrated structure, and three second cutter bodies 210C are fixedly arranged on each second cutter seat 210B, and adjacent second cutter bodies 210C are staggered according to a certain gap, which can improve the bag breaking effect. The second cutter body 210C is detachably installed on the second cutter seat 210B by bolt fixing, and the second cutter seat 210B is installed on the fixed cutter bracket 204. At the same time, a mounting plate 210A is fixedly provided on the upper frame 202, and the mounting plate 210A and the second tool holder 210B are rotatably connected, so that the second tool 210 is swingably mounted on the upper frame 202, and can be raised and lowered with the fixed tool bracket 204, thereby changing the distance between the second tool body 210C and the rotor roller 203.

[0063] Preferably, a plurality of swing cylinders 211 are also installed on the fixed knife support 204, each swing cylinder 211 is connected to a corresponding second knife seat 210B, and the second knife seat 210B is swingably installed on the upper frame 202 through the mounting plate 210A. The swing cylinder 211 is driven by the hydraulic device 500, and can adjust the angle between the mounting plate 210A and the upper frame 202, so as to further facilitate the adjustment of the distance and angle between the second knife body 210C and the rotor roller 203. Further preferably, while adjusting the distance and angle between the second knife body 210C and the rotor roller 203, the swing cylinder 211 is provided with an accumulator and a hydraulic lock, and the accumulator and the hydraulic lock are used to keep the second knife 210 at a constant pressure in the tearing and bagging process, and reduce the vibration impact in the tearing and bagging process.

[0064] Continue to refer to Figure 2 , Figure 3 As shown, the front frame 206 is located above the first support frame 201 and is arranged farther from the feed port of the tearing device 200 than the upper frame 202. The front frame 206 is also provided with a guide rail, and the scraper bracket 205 is slidably connected to the guide rail and performs lifting and lowering motion under the action of the second lifting assembly 213. The second lifting assembly 213 also adopts a gear rack structure, which can smoothly drive the scraper bracket 205 to lift and lower under the drive of the hydraulic device 500. A plurality of third knives 214 are detachably provided on the scraper bracket 205. The third knives 214 are in the shape of a hook bent toward the rotor roller 203 as a whole, and adopt an integrated structure formed by welding a third knife seat 214A and a third knife body 214B, so that the scraping and cleaning operation can be achieved with a relatively large pressure.

[0065] It should be noted that, in addition to the above-mentioned hydraulic device 500, the first lifting assembly 212, the second lifting assembly 213 and the swing cylinder 211 can also be driven separately by other driving devices, or the rotor assembly can also be driven by the hydraulic device 500, etc. The present invention does not make specific restrictions on these, as long as the above-mentioned tearing and bag removal, material return and anti-jamming, and scraping and cleaning can be achieved.

[0066] Optionally, in this embodiment, the bag tearing machine further includes a conveying device 100 , which is used to input the material into the tearing device 200 , and the conveying device 100 can convey the material in a direction away from the tearing device 200 .

[0067] Specifically, Figures 5 to 7 As shown, the conveying device 100 preferably adopts a chain belt conveyor, which is arranged on the feed port side of the tearing device 200, and includes a driving unit 101, a driving shaft 102, a driven shaft 109, a chain 107, a conveyor belt 108, a connecting plate and a frame structure 110 and other structures. The driving shaft 102, the driven shaft 109 and the frame structure 110 and other structures can install the chain 107 so that the chain 107 rotates along a preset direction. Connecting plates are connected between the chains 107, and the connecting plates and the conveyor belt 108 are fixedly connected. The conveyor belt 108 and the connecting plates move together, and have higher load-bearing capacity and conveying capacity.

[0068] More specifically, the drive unit 101 is connected to the drive shaft 102, and the drive shaft 102 is equipped with a sprocket 103, which can mesh with the chain 107 to transmit power and drive the chain 107 to rotate. The drive unit 101 adopts a variable frequency motor to drive the reducer configuration, which can not only provide adjustable different speeds and torques for the chain belt conveyor to meet the diverse material transportation needs, but also has the ability to run in reverse, so that when the tearing device 200 is performing material withdrawal and anti-jamming, it can run in reverse to avoid blockage at the feed port of the tearing device 200.

[0069] Two expansion sleeves 104 are arranged on the drive shaft 102, and a sprocket 103 is arranged on the outer side of the expansion sleeve 104 to ensure that there is no relative movement between the sprocket 103 and the drive shaft 102, thereby stably transmitting power. At the same time, two seat bearings 106 are also installed on the drive shaft 102. These bearings are fixed on the frame to provide a stable support for the drive shaft 102 and allow it to rotate smoothly under low friction conditions, ensuring the smooth operation of the entire conveying system.

[0070] In order to reduce the impact that may occur during the operation of the chain belt conveyor, especially when loaded, a shock absorbing unit 105 is specially provided on one side of the driving unit 101. This design effectively absorbs and disperses the vibration energy during operation, protects the driving unit 101, prolongs the service life of the equipment, and improves the stability of operation.

[0071] At the other end of the chain belt conveyor, the driven shaft 109 is configured in a similar manner and is also equipped with two expansion sleeves 104, two sprockets 103 and two seat bearings 106. Such a layout not only ensures a reliable connection between the driven shaft 109 and the chain 107, but also ensures the stability and continuity of the entire conveying path.

[0072] like Figure 8 As shown, the bag tearing machine also includes a storage bin 300, which is arranged above the conveyor belt 108 so that the materials can be stacked and stored on the conveyor belt 108. Specifically, the storage bin 300 includes a second support frame 301, a side plate 304, a guide plate 305, and a hopper assembly 303. Among them, the second support frame 301 is the skeleton structure of the storage bin 300, which is welded by square steel and channel steel. The structure is simple and strong, which can provide support for the link belt conveyor, ensuring the rigidity and stability of the bag tearing machine during operation, which is the basis for achieving efficient material processing.

[0073] A plurality of side panels 304 and guide plates 305 are installed on the second support frame 301, and form an enclosed space 302, which is the main storage space for materials. The side panels 304 constitute the outer boundary of the enclosed space 302, and the guide plates 305 are arranged between the side panels 304 and the conveyor belt 108, and are inclined toward the conveyor belt 108, so that the materials can fall smoothly onto the conveyor belt 108 under the guidance of the guide plates 305. Such a design not only improves the storage efficiency, but also ensures the orderliness of the materials during the conveying process.

[0074] like Fig. 9 As shown, the hopper assembly 303 includes a plurality of hopper plates, each of which is detachably fixed above the enclosed space 302 through the cooperation of the latch 307 and the socket 308 and the tightening action of the set screw. The hopper plate is similar to the guide plate 305 and is also tilted in the direction toward the conveyor belt 108, so that the storage bin 300 can form a larger trumpet-shaped opening at the top, which can facilitate the falling of materials and prevent the materials from falling out of the storage bin 300.

[0075] Preferably, a maintenance window 306 is also provided on the side panel 304, and the maintenance window 306 can provide a convenient maintenance passage and observation window for the staff. Through the maintenance window 306, the staff can easily maintain and inspect the inside of the storage bin, and timely discover and deal with potential problems, thereby ensuring the continuous and stable operation of the entire system.

[0076] like Fig.10 As shown, in this embodiment, the discharge chute device 400 is mainly composed of a main beam 401, a top connecting plate 402, a vertical connecting plate 403, a horizontal connecting plate 404 and a bottom chute 405. The various parts work together to ensure that the material after the tearing process can be smoothly transferred to the subsequent process equipment.

[0077] The main beam 401 is fixedly connected to the second support frame 301 and is used to support other structures such as the top connecting plate 402. The top connecting plate 402 is used to dock with the discharge port of the tearing device 200 to ensure that the processed materials can directly and smoothly enter the discharge chute device 400, thereby avoiding the scattering and waste of materials. The vertical connecting plate 403 and the horizontal connecting plate 404 are closely connected to the chain belt conveyor, and the stability and reliability of the entire bag tearing machine are enhanced through the connection in both vertical and horizontal directions. The bottom chute 405 is used to support the material to prevent the material from falling directly to the ground, thereby realizing the collection of the material.

[0078] The present invention also provides a method for using the bag tearing machine, which is applied to the above-mentioned bag tearing machine. The method for using the bag tearing machine specifically includes:

[0079] The second cutter 210 is moved in a direction approaching the rotor roller 203 until the second cutter 210 is inserted into between two adjacent first cutters 209 , and the third cutter 214 is moved in a direction away from the rotor roller 203 until the third cutter 214 is away from between two adjacent first cutters 209 .

[0080] The rotor roller 203 is driven to rotate in one of a clockwise direction and a counterclockwise direction to tear and remove the bag.

[0081] Specifically, in the above process, by moving the second cutter 210 in a direction close to the rotor roller 203 until the second cutter 210 extends into the space between two adjacent first cutters 209, a small and curved gap can be formed. At the same time, by moving the third cutter 214 in a direction away from the rotor roller 203 until the third cutter 214 leaves between two adjacent first cutters 209, the third cutter 214 can be prevented from hindering the movement of the material.

[0082] Then, when the rotor roller 203 continues to rotate in the clockwise direction, the first cutter 209 can carry the material to move, and when the material passes through the gap, the bag structure can be torn by the first cutter 209 and the second cutter 210, thereby releasing the recyclables in the bag structure and tearing the bag. Of course, in some other structures, according to the relative position between the specific first cutter 209 and the second cutter 210, the tearing and bag removal can also be achieved by rotating in the counterclockwise direction. Therefore, the specific rotation direction of the rotor roller 203 when tearing and bag removal is achieved in the present invention is not limited, as long as it is continuously rotated in one of the clockwise direction and the counterclockwise direction.

[0083] Through the above-mentioned method of using the bag tearing machine, compared with the continuous alternating forward and reverse rotation in the prior art, the impact vibration generated when breaking the bag can be greatly reduced, and the noise pollution to the surrounding environment can be reduced, thereby improving the working stability and service life of the bag tearing machine.

[0084] Specifically, the method for using the bag tearing machine also includes:

[0085] The second cutter 210 is moved in a direction away from the rotor roller 203 until the second cutter 210 leaves between two adjacent first cutters 209 ; the rotor roller 203 is driven to rotate in the other direction of the clockwise direction and the counterclockwise direction to perform material stripping and anti-jamming.

[0086] Specifically, in the above process, by moving the second cutter 210 in a direction away from the rotor roller 203 until the second cutter 210 leaves between two adjacent first cutters 209, a passage space with a larger spacing is formed, and the passage space can allow larger volume materials to pass through. After the passage space is formed, the rotation direction of the rotor roller 203 is reversed, and the material that originally could not pass through the gap or was stuck in the gap can be withdrawn from the feed port position of the tearing device 200, avoiding the situation of continuous material jamming. Compared with the operation of stopping the machine for disassembly and then manually removing the material in the prior art, it can greatly facilitate the normal use and maintenance of the bag tearing machine and reduce the loss of the bag tearing machine during use.

[0087] Specifically, the method for using the bag tearing machine also includes:

[0088] The third cutter 214 is reciprocated in a direction approaching and moving away from the rotor roller 203 , and the third cutter 214 is able to extend into between two adjacent first cutters 209 during the reciprocating motion to perform scraping and cleaning.

[0089] Specifically, in the above process, by reciprocating the third tool 214 in the direction approaching and moving away from the rotor roller 203, and allowing the third tool 214 to extend between two adjacent first tools 209 during the reciprocating motion, the third tool 214 can push out or hook out the material remaining between the first tools 209, thereby achieving scraping and cleaning, avoiding the complicated process of disassembling and cleaning.
