[0005] The aforementioned prior art effectively improves the output and working efficiency of unpacking machines, thereby enhancing the working efficiency of plastic product recycling production lines. However, the structure of the unpacking machine disclosed in the prior art is relatively broad and general, without addressing details such as the action coordination between multiple unpacking drums and the installation and fixing design of unpacking blades. The applicant has long been committed to the research and development or improvement of equipment related to recycling processes. This utility model aims to refine and improve the structure of the existing unpacking machine and its roller module to further enhance the working efficiency of the unpacking machine. Summary of the Invention

[0006] In view of the problems in the related technologies, this utility model proposes a roller module and a packaging unpacking machine suitable for packaging unpacking machines, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] The technical solution of this utility model is implemented as follows:

[0008] A roller module suitable for a pack unpacking machine includes X pack unpacking knife rollers, Y feeding rollers and Z first drive motors, where X≥2, Y≥1, and 1≤Z≤X+Y;

[0009] The first drive motor directly or indirectly drives the unpacking cutter roller and the feeding roller to rotate through a linkage mechanism;

[0010] Each of the unpacking knife rollers includes an unpacking shaft, a plurality of knife discs, and a plurality of unpacking knives;

[0011] A plurality of the aforementioned cutter discs are arranged sequentially along the axial direction of the unpacking rotating shaft, the cutter discs protruding outward from the outer peripheral surface of the unpacking rotating shaft, and the main disc body of the cutter discs being perpendicular to the axial direction of the unpacking rotating shaft;

[0012] The main disc of the cutter head is provided with several cutter grooves, and the unpacking knife can be detachably installed in the cutter grooves;

[0013] The unpacking knife has a mounting body that is detachably mounted on the knife groove. The edge of the mounting body away from the unpacking pivot continues to extend and contract in a direction away from the unpacking pivot to form an inclined tip. The inclined tip protrudes outward from the outer peripheral edge of the knife groove and the knife disc and is exposed.

[0014] The unpacking shaft, the cutter disc, and the unpacking blade of a single unpacking roller are relatively stationary.

[0015] The number and position of the unpacking knives on all the cutter discs are the same, all the unpacking knives on a single unpacking knife roller are aligned in the axial direction, all the unpacking knife rollers have the same structure, and after installation, the projection of the structure of all the unpacking knife rollers in the vertical plane is exactly the same.

[0016] When the unpacking knife roller rotates, the orientation of the inclined tip is in the same direction as the rotation direction.

[0017] Compared with existing technologies, firstly, during the unpacking process, the greatest wear occurs at the contact point between the unpacking blade and the recyclable waste. Therefore, this invention specifically designs the unpacking blade as a detachable structure. When the unpacking blade becomes dull or damaged, a single blade can be easily replaced without removing the entire unpacking blade roller for replacement or repair, simplifying maintenance. Secondly, this invention designs an inclined tip on the unpacking blade, aligning it with the rotation direction of the unpacking blade roller. This facilitates the unpacking blade gripping or inserting into the ton bag material, thereby pulling the material downwards and achieving the technical effect of breaking up the ton bag. Finally, this invention specifically designs all unpacking blades to be distributed and move in a consistent manner after installation, ensuring that as many unpacking blades as possible contact the ton bag with the roller module, avoiding incomplete unpacking and improving the efficiency and effect of breaking up ton bags.

[0018] Essentially, each of the unpacking cutter rollers and material-dispensing rollers can be driven by a first drive motor, i.e., Z = X + Y. Alternatively, it can be adapted so that two or more unpacking cutter rollers and material-dispensing rollers are driven by a single first drive motor, i.e., 1 < Z < X + Y. The inventors, through in-depth understanding and observation of the unpacking process, discovered that in practical applications, the unpacking and material-dispensing load of plastic ton bags is not large. Unpacking and material-dispensing can be achieved by designing a linkage mechanism and cooperating with a single motor, reducing the equipment production cost of this invention and facilitating simultaneous operation of all unpacking cutter rollers and material-dispensing rollers. Therefore, preferably, only one first drive motor is used. That is, when Z = 1, the linkage mechanism includes at least X + Y transmission chains. The output end of the first drive motor and the unpacking cutter rollers and material-dispensing rollers are equipped with gears adapted to the transmission chains, and each gear is connected in pairs through the transmission chains.

[0019] One of the first drive motors simultaneously drives all of the unpacking cutter rollers and feeding rollers to rotate.

[0020] Specifically, when Y=1 and Z=1, all the unpacking knife rollers and one feeding roller are arranged in sequence along the vertical direction, with the feeding roller located at the bottom.

[0021] The first side of the bottommost unpacking cutter roller is provided with two gears. One gear is linked to the first drive motor through a transmission chain, and the other gear is linked to the adjacent unpacking cutter roller through a transmission chain.

[0022] A gear is located on the second side of the bottommost unpacking cutter roller, which is linked to the feeding roller via a transmission chain;

[0023] Other unpacking rollers are connected in pairs via the transmission chain in an adjacent sequence to achieve linkage.

[0024] Preferably, the structures of all the unpacking cutter rollers do not overlap in the vertical plane, and the cutter discs of adjacent unpacking cutter rollers are staggered to ensure that the material being pulled out and broken down falls smoothly to the position of the feeding roller, thus avoiding material accumulation or jamming on the unpacking cutter rollers.

[0025] Preferably, the feeding roller includes a feeding shaft and several sets of feeding blades, and the several sets of feeding blades are arranged sequentially along the circumference of the feeding shaft;

[0026] Each set of material feeding blades includes at least two feeding blades. The feeding blades near the left and right outer edges are symmetrically inclined at 3 to 8 degrees to guide the dispersed material to gather in the middle of the feeding blades, preventing the material from scattering to both sides, improving the accuracy of material conveying to the next equipment, and speeding up the material entering the next process.

[0027] Preferably, the bottom of a single blade groove is provided with at least two mounting holes, and the mounting body of a single unpacking knife is provided with a through hole corresponding to the mounting holes. The blade groove and the unpacking knife are provided with screws passing through the mounting holes and the through holes and being fastened with nuts, thereby achieving detachable installation.

[0028] The width of the groove is adapted to the width of the unpacking knife, and the groove wall clamps the two sides of the unpacking knife, thereby preventing the unpacking knife from moving and avoiding the screw from being stressed and thus loosening or falling off.

[0029] This utility model also discloses a bag unpacking machine, including the above-mentioned roller module, frame and ton bag conveyor belt;

[0030] The roller assembly is mounted on the frame. The ton bag conveyor belt is provided on the first side of the roller assembly. The conveying direction of the ton bag conveyor belt is towards the position of the roller assembly. The end point of the ton bag conveyor belt is located between the unpacking cutter roller and the material-dispensing roller. The discharge cylinder is provided on the second side of the roller assembly corresponding to the position of the material-dispensing roller. The discharge cylinder is mounted on the frame. The rotation directions of the unpacking cutter roller and the material-dispensing roller are opposite.

[0031] The ton bag conveyor belt includes a second drive motor, a drive shaft, a driven shaft, and a chain plate belt. The chain plate belt connects the drive shaft and the driven shaft. The chain plate belt is horizontally arranged. The second drive motor directly or indirectly drives the drive shaft to rotate, thereby driving the chain plate belt to move.

[0032] The ton bags inevitably contain non-target recyclable materials such as sand and gravel, which are released during unpacking. If these materials are transported to the next process, they may damage the equipment. Therefore, preferably, a triangular slag discharge funnel is provided below the feeding roller on the frame. The slag discharge port of the slag discharge funnel faces the side of the frame. The spacing of the feeding blades is designed to intercept the target recyclable materials, while non-target recyclable materials such as sand and gravel pass through the gaps between the feeding blades and then leak out through the slag discharge funnel. This achieves the removal of non-target recyclable materials such as sand and gravel and reduces the difficulty of subsequent cleaning and screening. On the other hand, a slag receiving plate is provided below the chain belt to receive the material (mainly sand and gravel) that leaks down from the chain belt. The edge of the slag receiving plate near the feeding roller is connected to the top of the slag discharge funnel.

[0033] Preferably, the left and right sides of the slag receiving pan are provided with pan sidewalls to prevent slag leakage. At the same time, the pan sidewalls are provided with viewing windows at equal intervals to observe the slag accumulation at different positions of the slag receiving pan. The side of the slag receiving pan away from the slag discharge funnel is an open structure, and the waste on the slag receiving pan can be pushed to the slag discharge funnel on the other side by a long-handled broom or a blower to be discharged and collected, so as to achieve cleaning of the slag receiving pan.

[0034] Preferably, the unpacking cutter roller, the feeding roller, the drive shaft, and the driven shaft can all be detachably installed on the frame for easy disassembly and maintenance.

[0035] Preferably, the frame is equipped with cover plates at the positions corresponding to the transmission chain and gears to prevent dust and impurities from entering the gaps of the linkage mechanism and accumulating, thus affecting operation. It also prevents the linkage mechanism from being exposed, thus protecting on-site personnel.

[0036] Preferably, the frame is provided with a no-guardrail area, a low-guardrail area, and a high-guardrail area along the conveyor belt. The main functions are: to maximize the visibility range without affecting the original function of each guardrail, so as to facilitate the staff to monitor the operation of the equipment in real time and make timely adjustments; the high guardrail is level with the highest point of the unpacking cutter roller to prevent material from scattering; the low guardrail area is lower than half the height of the high guardrail area, so as to guide and correct the movement trajectory of the ton bags entering the conveyor belt.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0062] Example 1

[0063] A roller module suitable for a pack unpacking machine includes X pack unpacking knife rollers 1, Y material feeding rollers 2, and Z first drive motors 3, where X ≥ 2, Y ≥ 1, and 1 ≤ Z ≤ X + Y. (Refer to...) Figures 1 to 4 This embodiment uses X=4, Y=1, Z=1 as an example for illustration.

[0064] The first drive motor 3 drives the unpacking knife roller 1 and the feeding roller 2 to rotate directly or indirectly through the linkage mechanism. In this embodiment, the roller speed is 85 r / min.

[0065] Each of the unpacking rollers 1 includes an unpacking shaft 101, multiple cutter discs 102 and multiple unpacking blades 103, wherein the unpacking blades 103 are made of NM360 wear-resistant steel plate;

[0066] Multiple cutter discs 102 are arranged and fixed at equal intervals along the axial direction of the unpacking shaft 101 by welding process. The cutter discs 102 protrude outward from the outer peripheral surface of the unpacking shaft 101, and the main disc of the cutter disc 102 is perpendicular to the axis of the unpacking shaft 101.

[0067] The main body of the cutter disc 102 is provided with a plurality of cutter grooves 102a. In this embodiment, a single cutter disc 102 is provided with 3 cutter grooves 102a. The plurality of cutter grooves 102a are evenly distributed in a circle. The unpacking knife 103 can be detachably installed in the cutter grooves 102a.

[0068] The unpacking knife 103 has a mounting body 103a. Considering that the greatest wear occurs at the contact point between the unpacking knife 103 and the recyclable waste during the unpacking process, this embodiment is specifically designed so that the mounting body 103a can be detachably mounted on the knife groove 102a. When the unpacking knife 103 becomes chipped or damaged, a single unpacking knife 103 can be easily replaced without removing the entire unpacking knife roller 1 for replacement or treatment, which is convenient for maintenance.

[0069] Specifically, at least two mounting holes are provided at the bottom of the groove of a single blade groove 102a, and a through hole corresponding to the mounting holes is provided on the mounting body 103a of a single unpacking knife 103. The blade groove 102a and the unpacking knife 103 are provided with screws passing through the mounting holes and through holes and being fastened with nuts, thereby achieving detachable installation.

[0070] The width of the groove 102a is adapted to the width of the unpacking knife 103. The groove wall of the groove 102a clamps the two sides of the unpacking knife 103, thereby preventing the unpacking knife 103 from moving and avoiding the screw from being stressed and thus loosening or falling off.

[0071] The mounting body 103a extends and contracts away from the unpacking shaft 101, forming an inclined tip 103b. In this embodiment, the unpacking knife 103 has an approximately right-angled trapezoidal structure. The inclined tip 103b protrudes from the outer periphery of the knife groove 102a and the knife disc 102, and is exposed. This facilitates the unpacking knife 103 to grip or insert into the ton bag material, thereby pulling the material down and achieving the technical effect of breaking up the ton bag.

[0072] The unpacking shaft 101, the cutter disc 102, and the unpacking cutter 103 of the single unpacking roller 1 are relatively stationary.

[0073] The number and position of the unpacking knives 103 on all the cutter discs 102 are the same, all the unpacking knives 103 on a single unpacking knife roller 1 are aligned in the axial direction, all the unpacking knife rollers 1 have the same structure, and after installation, the projection of the structure of all the unpacking knife rollers 1 in the vertical plane is exactly the same.

[0074] When the unpacking roller 1 rotates, the inclined tip 103b faces the same direction as the rotation, so that when the ton bag comes into contact with the roller module, each unpacking roller 1 has as many unpacking blades 103 as possible in contact with the ton bag. As shown in the example device in this embodiment, 44 unpacking blades 103 come into contact with the ton bag with each rotation, avoiding incomplete unpacking and improving the efficiency and effect of dispersing the ton bag.

[0075] When Z=1, the linkage mechanism includes at least X+Y transmission chains 4. The output end of the first drive motor 3, the unpacking cutter roller 1, and the feeding roller 2 are all equipped with gears adapted to the transmission chains 4. Each gear is connected in pairs through the transmission chains 4.

[0076] One of the first drive motors 3 simultaneously drives all of the unpacking cutter rollers 1 and the feeding rollers 2 to rotate.

[0077] Specifically, in this embodiment, when X=4, Y=1, and Z=1, all the unpacking rollers 1 and one material-pushing roller 2 are arranged in sequence along the vertical direction, with the material-pushing roller 2 located at the bottom, pushing the dispersed material toward the target direction.

[0078] Considering that the standard height of a ton bag is ≤1.2m, the unpacking cutter roller 1 at the bottom is used as the horizontal reference, and the unpacking cutter roller 1 at the top is set at a horizontal height of 1.5m, which can be applied to more occasions and different types of incoming materials.

[0079] Meanwhile, two gears are provided on the first side of the bottommost unpacking knife roller 1. One gear is linked to the first drive motor 3 through the transmission chain 4, and the other gear is linked to the adjacent unpacking knife roller 1 through the transmission chain 4.

[0080] A gear is provided on the second side of the unpacking cutter roller 1 located at the bottom, which is linked to the feeding roller 2 via the transmission chain 4;

[0081] Other unpacking rollers 1 are connected in pairs via the transmission chain 4 in an adjacent sequence for linkage.

[0082] Reference Figure 2In this embodiment, the structures of all the unpacking knife rollers 1 do not overlap in the vertical plane projection, that is, there is a gap between the unpacking knives 103 at the upper and lower positions, and the knife discs 102 of adjacent unpacking knife rollers 1 are staggered and arranged to leave space so that the material that has been pulled out and broken can fall smoothly to the feeding roller 2, avoiding material accumulation and jamming.

[0083] In this embodiment, the feeding roller 2 includes a feeding shaft 202 and several groups of feeding blades 201 (specifically, four groups of equally spaced feeding blades), and the several groups of feeding blades 201 are arranged sequentially along the circumference of the feeding shaft 202.

[0084] The single set of feeding blades 201 includes at least two feeding blades 201a (in this embodiment, the single set of feeding blades 201 has six feeding blades 201a), and the feeding blades 201a of adjacent feeding blade sets 201 are staggered. Figure 4 The material-pulling blades 201a near the left and right outer sides are symmetrically tilted at 3 to 8 degrees (specifically 5 degrees) to guide the dispersed material to gather in the middle, prevent the material from scattering to both sides, improve the accuracy of conveying, and speed up the material's entry into the next process.

[0085] Example 2

[0086] Reference Figures 1 to 8 A package unpacking machine includes the roller assembly, frame, and ton bag conveyor belt of Embodiment 1.

[0087] The roller module is installed on the frame. The ton bag conveyor belt is set on the first side of the roller module. The conveying direction of the ton bag conveyor belt is towards the position of the roller module. The end point of the ton bag conveyor belt is located between the unpacking cutter roller 1 and the material-dispensing roller 2. The second side of the roller module is provided with a downwardly inclined discharge cylinder 14 corresponding to the position of the material-dispensing roller 2, which facilitates accurate docking with the conveying or processing equipment of the next process in this embodiment. The rotation directions of the unpacking cutter roller 1 and the material-dispensing roller 2 are opposite.

[0088] The ton bag conveyor belt includes a second drive motor 10, a frequency converter, a drive shaft 11, a driven shaft 12, and a chain plate belt 8 with superior load-bearing capacity and wear resistance. The chain plate belt 8 connects the drive shaft 11 and the driven shaft 12. The chain plate belt 8 is horizontally arranged. The second drive motor directly or indirectly drives the drive shaft 11 to rotate, thereby driving the chain plate belt 8 to move. Specifically, in this embodiment, the rotational speed of the second drive motor 10 combined with the frequency converter is 0.05 m / s, which is adapted to the feeding speed of the roller module.

[0089] In this embodiment, the effective conveying length of the chain plate belt 8 is about 4 meters, which can hold at least 3 ton bags in practical applications.

[0090] The ton bags inevitably contain non-target recyclable materials such as sand and gravel, which are released during unpacking. If these materials are transported to the next process, they may damage the equipment. Therefore, in this embodiment, a triangular slag discharge funnel 13 is provided below the feeding roller 2 on the frame, with the slag discharge port of the slag discharge funnel 13 facing the side of the frame. The spacing of the feeding blades 201a is designed to trap the target recyclable material, while non-target recyclable materials such as sand and gravel pass through the gaps between the feeding blades 201a and then leak out through the slag discharge funnel 13, thereby achieving the screening out of non-target recyclable materials such as sand and gravel. On the other hand, a slag receiving plate 9 is provided below the chain belt 8 to receive the material (mainly sand and gravel) that leaks down from the chain belt 8. The slag receiving plate 9 is located near the edge of the feeding roller 2 and connects to the top of the slag discharge funnel 13.

[0091] In this embodiment, the left and right sides of the slag receiving pan 9 are provided with pan sidewalls to prevent slag leakage. At the same time, the pan sidewalls are provided with viewing windows 901 at equal intervals to observe the slag accumulation of the slag receiving pan 9. The side of the slag receiving pan 9 away from the slag discharge funnel 13 is an open structure, and the waste on the slag receiving pan 9 can be pushed to the slag discharge funnel 13 on the other side by a long-handled broom or a blower to achieve cleaning of the slag receiving pan 9.

[0092] In this embodiment, the unpacking roller 1, the feeding roller 2, the drive shaft 11, and the driven shaft 12 can all be detached and installed on the frame for easy disassembly and maintenance.

[0093] In this embodiment, the frame is provided with cover plates 5 at the positions of the transmission chain 4 and gears to prevent impurities from entering the gap of the linkage mechanism and thus affecting the operation. It also prevents the linkage mechanism from being exposed, thus protecting the personnel on site.

[0094] In this embodiment, the frame is provided with a high guardrail area 6, a low guardrail area 7, and a guardrail-free area in sequence along the transport direction of the chain conveyor belt 8. The main functions are: to maximize the visibility range without affecting the original function of each guardrail, so as to facilitate the staff to monitor the operation of the equipment in real time; the high guardrail is level with the highest point of the unpacking cutter roller 1 to prevent material from scattering; the low guardrail area 7 is lower than half the height of the high guardrail area 6, so as to guide and correct the movement trajectory of the ton bags entering the conveyor belt.

[0095] Based on the disclosure and teachings of the foregoing specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the protection scope of the claims of the present invention. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the present invention.
