Description

Technical Field

[0001] The present invention relates to the technical field of raw material crushing and processing, and in particular to a device and a production method for processing secondary recycled raw materials of packaging cartons. Background Art

[0002] The packaging carton secondary recycling raw material processing device is a mechanical device specially used to convert discarded cartons into reusable raw materials. It has a wide range of application scenarios, including e-commerce warehouses, product manufacturing plants, express distribution centers, and waste paper recycling stations. The function of this device is to restore the basic properties of used cartons as papermaking raw materials through steps such as crushing. Its significance lies in, firstly, reducing the landfill and incineration of waste cartons and reducing environmental pollution; secondly, saving virgin pulp resources and improving resource utilization; thirdly, reducing packaging costs for enterprises; and finally, promoting the development of the circular economy and promoting the formation of green production and consumption patterns.

[0003] Traditional processing devices are widely used in raw material processing, but due to the limitations of their structure and working principle, there are often some problems that cannot be ignored. For example, when processing cartons, traditional packaging carton secondary recycling raw material processing devices often face a problem: they cannot effectively separate plastic parts such as tapes on cartons from paper fibers. They may be partially degraded and mixed into the pulp, affecting the quality of recycled paper. This causes the performance of recycled paper to deteriorate due to plastic impurities in subsequent use. This processing device has limitations in improving the recycling rate of cartons, and technological innovation is urgently needed to achieve the separation of cartons and plastic tapes. During the recycling process, traditional packaging carton secondary recycling raw material processing devices cannot clean plastic parts such as tapes on cartons in a timely manner. Due to the lack of a cleaning mechanism, plastic tape fragments will accumulate inside the device, resulting in a decrease in equipment operating efficiency and may even cause mechanical failures. This not only increases maintenance costs and downtime, but also reduces the quality of recycled pulp. Therefore, the shortcomings of this processing device in the treatment of plastic impurities limit its application effect in the field of packaging carton recycling. Summary of the invention

[0004] In view of the problem that the existing technology cannot effectively separate the plastic parts such as the tape on the carton from the paper fibers, a raw material processing device for secondary recycling of packaging cartons is proposed.

[0005] The purpose is to separate plastic parts such as tapes from paper fibers and clean up the separated plastics such as tapes.

[0006] The technical solution of the present invention is a packaging carton secondary recycling raw material processing device, comprising a frame, a hopper arranged on the top of the frame, a feed rod arranged inside the frame, a crushing mechanism arranged on a side of the frame away from the feed rod, and a separation mechanism arranged inside the crushing mechanism;

[0007] The crushing mechanism includes a rotor arranged on the side of the feed rod away from the hopper, a cylinder arranged on the frame close to the outer side of the rotor, a concave plate arranged on the side of the cylinder away from the rotor, a concave hole opened in the middle of the concave plate, a bracket arranged on the side of the cylinder close to the concave plate, a stepped hole opened on the side of the bracket close to the rotor, three annular arrays of support shafts arranged on the side of the stepped hole close to the rotor, a planetary gear arranged on the outer side of the support shaft, a gear ring arranged on the side of the rotor close to the planetary gear, a reciprocating screw arranged on the side of the stepped hole away from the planetary gear, a sun gear arranged on the side of the reciprocating screw close to the planetary gear, the outer side of the sun gear meshing with the planetary gear, a net cylinder arranged on the side of the cylinder close to the concave plate, two annular arrays of slide grooves opened on the inner wall of the net cylinder, a side plate arranged on the side of the frame away from the hopper, three annular arrays of air pipes arranged on the side of the side plate away from the hopper, three annular arrays of discharge pipes arranged on the side of the side plate away from the hopper, and two symmetrically arranged air ducts on the side of the frame close to the hopper;

[0008] The cam is an axially-guided sliding mechanism, and the cam is an actuating member that is adapted to move relative to the cam, and the cam is adapted to move relative to the cam when the cam is in motion.

[0009] Furthermore, a through hole is provided in the middle of the limiting sleeve, and three discharge ports are provided in an annular array on the side of the limiting plate close to the side plate.

[0010] Furthermore, the diameter of the through hole matches the diameter of the reciprocating screw rod, and the outer shape of the push rod is L-shaped.

[0011] Furthermore, the inner diameter of the air pipe is the same as the width of the discharge port, and the shape of the inner wall of the discharge pipe is the same as the shape of the discharge port.

[0012] Furthermore, the inclined block 1 and the inclined block 2 are both provided with inclined surfaces with the same inclination angle, and the directions of the inclined surfaces are opposite.

[0013] Furthermore, the thickness of the containing groove matches the thickness of the mesh plate, and the side of the mesh plate is provided with through mesh holes.

[0014] Furthermore, the diameter of the movable plate matches the inner diameter of the mesh cylinder, and the shape of the slider matches the cross section of the slide groove.

[0015] Furthermore, a circular protrusion is provided in the middle of the push rod, and the inner wall of the sliding hole is adapted to the push rod.

[0016] Another object of the present invention is to provide a method for processing and producing packaging cartons for secondary reuse of raw materials, the purpose of which is to process the cartons so as to achieve the purpose of reuse.

[0017] To achieve the above object, the present invention provides the following technical solution: a method for processing and producing secondary recycled raw materials of packaging cartons, comprising the following steps:

[0018] First, the collected cartons are classified according to material, degree of contamination, size and strength;

[0019] The cartons are then crushed into smaller pieces or chunks for easier processing;

[0020] Finally, the crushed cartons are put into a crusher, where the paper fibers are separated and cut by mechanical action to form paper fluff, which is then made into pulp.

[0021] Furthermore, the processed pulp is poured into a forming machine, and the water is filtered through a mesh to form a wet paper sheet. Then, the wet paper sheet undergoes processes such as pressing, drying and winding to finally form a recycled carton board or paper.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The crushing mechanism can separate the plastic parts such as tape in the carton. The crushing mechanism uses crushing and screening methods to break the carton into paper fibers and plastic impurities, and then separates the plastic fragments from the paper fibers through wind screening. This innovative design not only improves the purity of the raw materials and ensures the quality of the recycled pulp, but also enhances the environmental protection and economy of the entire recycling process, providing a more efficient and sustainable solution for the recycling of packaging cartons.

[0024] 2. The separated plastics and tapes can be cleaned up through the separation mechanism. The mechanism can further separate the broken plastic fragments and tapes from the paper fibers and carry out centralized treatment. This step ensures that the plastics and tapes are effectively recycled, avoids contamination of recycled pulp, and improves the quality of the final product. At the same time, the cleaned plastics and tapes can be sent to professional recycling units and converted into other plastic products, thereby maximizing the utilization of resources and reducing environmental pollution.

[0025] 3. Through the setting of the push rod and push block, the secondary recycling material processing device for packaging cartons can flexibly adapt to the movement direction of the moving plate, thereby controlling the rotation angle of the screen plate. This mechanism enables the screen plate to quickly follow and adjust when the moving plate changes direction, thereby intercepting and collecting the tape. This method improves the efficiency of cleaning the tape, reduces the need for manual intervention, and ensures the operation of the production line. The setting of the push rod and push block not only optimizes the tape separation process, but also improves the automation level of the overall equipment, providing more efficient hardware support for the recycling and reuse of packaging cartons.

[0041] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0042] Example 1, reference Figure 1-Figure 13, which is the first embodiment of the present invention, provides a packaging carton secondary recycling raw material processing device, including a frame 1, a hopper 2 fixedly connected to the top of the frame 1, a feed rod 3 rotatably connected to the inside of the frame 1, and also includes a crushing mechanism 4 fixedly connected to the side of the frame 1 away from the feed rod 3, and a separation mechanism 5 fixedly connected to the inside of the crushing mechanism 4; the crushing mechanism 4 includes a rotor 41 fixedly connected to the side of the feed rod 3 away from the hopper 2, a cylinder 42 fixedly connected to the frame 1 close to the outside of the rotor 41, a concave plate 43 fixedly connected to the side of the cylinder 42 away from the rotor 41, a concave hole 44 opened in the middle of the concave plate 43, a bracket 45 fixedly connected to the side of the cylinder 42 close to the concave plate 43, a stepped hole 46 opened on the side of the bracket 45 close to the rotor 41, and three annular arrays of support shafts fixedly connected to the stepped hole 46 close to the rotor 41 47, a planetary gear 48 rotatably connected to the outside of the support shaft 47, a gear ring 49 fixedly connected to the rotor 41 on the side close to the planetary gear 48, a reciprocating screw 410 rotatably connected to the side of the stepped hole 46 away from the planetary gear 48, a sun gear 411 fixedly connected to the reciprocating screw 410 on the side close to the planetary gear 48, the outer side of the sun gear 411 meshing with the planetary gear 48, a net cylinder 412 fixedly connected to the side of the cylinder 42 close to the concave plate 43, two annular arrays of slide grooves 413 opened on the inner wall of the net cylinder 412, a side plate 414 fixedly connected to the side of the frame 1 away from the hopper 2, three annular arrays of air pipes 415 fixedly connected to the side of the side plate 414 away from the hopper 2, three annular arrays of discharge pipes 416 fixedly connected to the side of the side plate 414 away from the hopper 2, and two symmetrically fixedly connected air ducts 417 to the side of the frame 1 close to the hopper 2;The separation mechanism 5 includes a sleeve 51 slidably connected to the outside of the reciprocating screw rod 410, an inclined block 52 fixedly connected to the bottom of the sleeve 51, a sliding hole 53 opened at the top of the sleeve 51, a push rod 54 slidably connected to the inside of the sliding hole 53, a push block 55 fixedly connected to the bottom of the push rod 54, a moving plate 56 fixedly connected to the side of the sleeve 51 close to the concave plate 43, two sliders 57 symmetrically fixedly connected to the outside of the moving plate 56, a receiving groove 58 opened in the moving plate 56, a mesh plate 59 rotatably connected to the inside of the receiving groove 58, a sleeve 510 fixedly connected to the side of the mesh plate 59 close to the push rod 54, a driving groove 511 opened at the top of the sleeve 510, and a moving plate 56 rotatably connected to the moving plate 51. The closing plate 512 on the side of the moving plate 56 close to the push block 55, the rotating drum 513 fixedly connected to the closing plate 512 away from the concave plate 43, the turning groove 514 opened on the top of the rotating drum 513, the limiting sleeve 515 fixedly connected to the side of the side plate 414 close to the net cylinder 412, the top rod 516 fixedly connected to the side of the limiting sleeve 515 away from the side plate 414, the flow limiting plate 517 rotatably connected to the side of the side plate 414 close to the limiting sleeve 515, the inclined block 2 518 fixedly connected to the flow limiting plate 517 close to the bottom of the limiting sleeve 515, and the torsion spring 519 sleeved on the middle of the limiting sleeve 515, the two ends of the torsion spring 519 are respectively fixedly connected to the limiting sleeve 515 and the flow limiting plate 517. ;

[0043] Specifically, the carton is cut into small pieces of paper and then put into the hopper 2. The paper pieces fall into the range of the feed rod 3 through the hopper 2. The feed rod 3 rotates and transports the paper pieces to the position of the rotor 41. The feed rod 3 rotates and drives the rotor 41 to rotate. The rotor 41 crushes the paper pieces into fibrous paper fluff while rotating. The tape in the paper piece has stronger ductility than the paper piece, so it will remain in a relatively complete state, thereby realizing the separation of the tape and the paper fluff. The air flow is blown into the inside of the cylinder 42 through the air duct 417, and the lighter paper fluff and the separated tape are blown to the inside of the net cylinder 412 by the air flow, and the air flow passes through the air duct 417. 15 blows air into the inside of the net cylinder 412. Since the volume of paper fluff is small, it will pass through the mesh to the outside of the net cylinder 412 and then be discharged from the bottom of the frame 1. Since the volume of the tape is large, it will remain in the inside of the net cylinder 412. The plastic parts such as the tape in the carton can be separated by the crushing mechanism 4. The crushing mechanism 4 uses the crushing and screening method to break the carton into paper fibers and plastic impurities, and then separates the plastic fragments from the paper fibers through wind screening. This innovative design not only improves the purity of the raw materials and ensures the quality of the recycled pulp, but also enhances the overall recycling process. In order to improve the environmental protection and economy of the treatment process, the rotor 41 drives the planetary gear 48 to rotate through the gear ring 49 while rotating, and the planetary gear 48 drives the reciprocating screw 410 to rotate through the sun gear 411. When the reciprocating screw 410 rotates, the push block 55 will be squeezed by the thread, and the push block 55 drives the push rod 54 to move. The push rod 54 will slide inside the slide hole 53 until it slides to the maximum stroke, and then drives the sliding sleeve 51 to move. When the sliding sleeve 51 moves, it also moves with the moving plate 56. The moving plate 56 cannot rotate because it is constrained by the slider 57, and can only move along the reciprocating screw 410. The movable plate 56 moves, while driving the mesh plate 59 and the closing plate 512 to move together, so as to intercept and concentrate the tape. The separation mechanism 5 can clean the separated plastic and tape. The mechanism can further separate the broken plastic fragments and the tape from the paper fiber and carry out centralized treatment. This step ensures that the plastic and tape are effectively recycled, avoids contamination of recycled pulp, and improves the quality of the final product. At the same time, the cleaned plastic and tape can be sent to professional recycling units and converted into other plastic products, so as to maximize the utilization of resources and reduce environmental pollution.

[0044] Reference Fig.11 A through hole 520 is opened in the middle of the limiting sleeve 515 , and three discharge ports 521 are opened in an annular array on the side of the limiting plate 517 close to the side plate 414 .

[0045] Specifically, the air pipe 415 can deliver airflow toward the inside of the mesh cylinder 412, so as to blow the paper fluff out of the inside of the mesh cylinder 412, and the discharge port 521 is connected to negative pressure for suction.

[0046] Reference Fig.12 The diameter of the through hole 520 matches the diameter of the reciprocating screw rod 410, and the outer shape of the top rod 516 is L-shaped.

[0047] Specifically, the through hole 520 of the limiting sleeve 515 can accommodate the reciprocating screw rod 410 to pass through, and the push rod 516 can push the closing plate 512 to rotate.

[0048] Example 2, reference Fig.11 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that the inner diameter of the air pipe 415 is the same as the width of the discharge port 521 , and the inner wall shape of the discharge pipe 416 is the same as the shape of the discharge port 521 .

[0049] Specifically, the airflow of the air pipe 415 enters the mesh cylinder 412 through the discharge port 521, and the discharge port 521 can suck out the concentrated tape. At the same time, the flow limiting plate 517 will make only one of the air pipe 415 and the discharge port 521 maintain the state.

[0050] Reference Figure 8 and Fig.10 The inclined block 1 52 and the inclined block 2 518 are both provided with inclined surfaces with the same inclination angle, and the directions of the inclined surfaces are opposite.

[0051] Specifically, the first inclined block 52 and the second inclined block 518 can match each other, and the first inclined block 52 can squeeze the second inclined block 518 to rotate it, and the rotation of the second inclined block 518 will drive the limiting plate 517 to rotate.

[0052] Reference Fig. 9 The thickness of the receiving groove 58 matches the thickness of the mesh plate 59, and the side of the mesh plate 59 is provided with through mesh holes.

[0053] Specifically, the receiving groove 58 can accommodate the mesh plate 59 to rotate inside. When the mesh plate 59 moves to the inside of the receiving groove 58 and is in a state of being blocked by the movable plate 56, the interception of the tape will be released.

[0054] Reference Figure 7-Figure 8 The diameter of the movable plate 56 matches the inner diameter of the net cylinder 412 , and the shape of the slider 57 matches the cross section of the slide groove 413 .

[0055] Specifically, the movable plate 56 can move inside the net cylinder 412, and after the slider 57 and the slide groove 413 cooperate, the freedom of movement of the movable plate 56 will be restricted so that it cannot rotate.

[0056] Reference Fig.10 A circular protrusion is provided in the middle of the push rod 54 , and the inner wall of the sliding hole 53 is adapted to the push rod 54 .

[0057] Specifically, the circular protrusion of the push rod 54 can prevent the push rod 54 from falling off from the sliding interior, and the sliding hole 53 can limit the stroke of the push rod 54. The remaining structure is the same as that of Example 1.

[0058] Based on the embodiments 1-2, the working principle of the present invention is as follows: the carton is divided into small pieces and put into the equipment through the hopper 2. After the paper pieces enter the hopper 2, they are sent by the feed rod 3 into the rotating area of ​​the rotor 41 to be broken into paper fluff, thereby being separated from the tape, and then transported to the inside of the net cylinder 412 for separation. In this process, the air duct 417 will blow air into the inside of the cylinder 42. While the feed rod 3 rotates, it will drive the rotor 41 to rotate. After the rotor 41 rotates, the paper pieces are beaten into fibrous paper fluff. The tape will not be broken because it has higher ductility than the paper pieces. Since the paper fluff and the tape are lighter in weight, they are brought into the inside of the net cylinder 412 by the air flow blown out by the air duct 417. At this time, the air pipe 415 blows air into the inside of the net cylinder 412, and the paper fluff is driven by the air flow. The tape moves out of the net cylinder 412 through the mesh, and then falls from the bottom of the frame 1. Due to its large size, the tape will be intercepted by the net cylinder 412. The rotor 41 rotates while driving the gear ring 49. The gear ring 49 drives the sun gear 411 to rotate through the planetary gear 48. The sun gear 411 drives the reciprocating screw 410 to rotate. The reciprocating screw 410 rotates while driving the push block 55 and the push rod 54 to move. After the push rod 54 moves to the maximum stroke in the slide hole 53, it drives the sliding sleeve 51 to move synchronously. The sliding sleeve 51 drives the moving plate 56 to move in the same direction. The moving plate 56 drives the net plate 59 and the closing plate 512 to move together. When the push block 55 and the push rod 54 move toward the direction of the concave plate 43, the sleeve 51 will be driven by the extrusion driving groove 511. 0 rotates, the sleeve 510 drives the mesh plate 59 to rotate synchronously, so that the mesh plate 59 rotates to the inside of the accommodating groove 58, so as to no longer block the paper fluff and the adhesive tape. After the push block 55 moves to the maximum stroke toward the concave plate 43, it begins to move toward the direction close to the side plate 414. At this time, the reciprocating screw rod 410 will drive the push rod 54 to move in the same direction through the push block 55. The push rod 54 moves in the sliding hole 53 toward the side plate 414 and squeezes the driving groove 511 while moving, so that the sleeve 510 and the mesh plate 59 are reset. At this time, the paper fluff can pass through the mesh plate 59 driven by the airflow, and the adhesive tape will be intercepted by the mesh plate 59. The push rod 54 drives the sliding sleeve 51 and the movable plate 56 to move toward the side plate 414. When it moves to a position close to the side plate 414, After the positioning, the push rod 516 will dock with the steering groove 514, and push the rotating drum 513 to rotate through the steering groove 514. The rotating drum 513 drives the closing plate 512 to rotate at the same time. After the closing plate 512 rotates, it will block the mesh plate 59, so that neither paper wool nor tape can pass through the mesh plate 59. The sliding sleeve 51 moves and drives the inclined block 1 52 to move. After the closing plate 512 blocks the mesh plate 59, the inclined block 1 52 will contact and squeeze the inclined block 2 518 to rotate the inclined block. After the inclined block rotates, it drives the flow limiting plate 517 to rotate. When the flow limiting plate 517 rotates, the torsion spring 519 accumulates force, and the discharge port 521 is aligned with the discharge pipe 416. At the same time, the air pipe 415 is blocked, so that negative pressure is formed between the flow limiting plate 517, the closing plate 512 and the movable plate 56.The intercepted tape will be sucked out through the discharge pipe 416. After the push block 55 moves to the maximum stroke, it will move in the opposite direction again and drive the sliding sleeve 51 to move together, thereby releasing the squeezing of the inclined block 1 52 on the inclined block 2 518. The flow limiting plate 517 will be reset under the action of the torsion spring 519, closing the discharge pipe 416 and opening the air pipe 415. At this time, the push rod 516 will drive the rotating drum 513 and the closing plate 512 to reset through the turning groove 514.

[0059] Example 3, reference Figure 1-Figure 13 , which is the third embodiment of the present invention, provides: a method for processing and producing secondary recycled raw materials of packaging cartons, comprising the following steps:

[0060] S1, first of all, the collected cartons are classified according to material, degree of contamination, size and strength, etc. Different types of cartons need to be processed in different ways.

[0061] S2, then crush the cartons into smaller pieces or blocks for subsequent processing. Small pieces or blocks of cartons are easier to carry out subsequent processing.

[0062] S3, finally, the crushed cartons are put into a crusher, and the paper fibers are separated and cut by mechanical action to form paper fluff, and the paper fluff is made into pulp. Making the paper fluff into pulp will make it easier to shape the paper fibers.

[0063] S4, pour the processed pulp into the forming machine, filter the water through the mesh to form wet paper sheets, and then the wet paper sheets go through processes such as pressing, drying and winding to finally form recycled carton boards or paper. After a series of processing, the finished cartons or paper will be put into use again.

[0064] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
