Description

Technical Field

[0001] The present invention relates to the technical field of recycling of paper products, and specifically provides a paper product classification and recycling device with a crushing structure. Background Art

[0002] The paper product classification and recycling device with a crushing structure realizes the recycling of paper resources through automated sorting and efficient crushing technologies. This device uses rotary blades to cut waste paper into uniform chips for subsequent processing. Recycling and reusing paper products can save multiple resources such as trees, water resources, and electric energy, significantly reduce landfill pollution, and promote the coordinated development of environmental protection and resource circular economy.

[0003] For example, Chinese Patent (Publication No.: CN111298887B) discloses a paper product classification and recycling and crushing device, which includes a crushing box. One side of the outer wall of the crushing box is bolted to a feeding box. The top of the feeding box is welded with a plurality of feeding ports. One side of the outer wall of the feeding box is bolted to a drying box, and a plurality of drying pipes are welded to one side of the outer wall of the drying box. A drying fan is bolted inside the drying box. A partition is adhesively bonded to the inner wall of the feeding box, and an inclined plate is welded between one side of the outer wall of the partition and the inner wall of the feeding box. A plurality of liquid dripping holes are formed inside the inclined plate. The beneficial effects of this invention are as follows: Dry paper products and relatively moist paper products respectively enter the inside of the crushing box through the feeding box, enabling classified crushing of dry paper products and relatively moist paper products, and the relatively moist paper products can be dried, which is convenient to use. The paper material is collected and poured into the crushing port for crushing again. The paper material after multiple crushings has a better crushing effect.

[0004] However, this device is not convenient for the subsequent utilization of paper products. When reusing paper products, different paper products need to be manufactured according to the fiber length after crushing.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 to 2 , a paper product classification and recycling device with a crushing structure in this embodiment, including a feeding box 1, a discharging box 3 is fixed at the bottom of the feeding box 1, a processing box 2 fixedly communicated with the feeding box 1 is fixedly connected to the right side of the discharging box 3, a pretreatment component 4 for preliminarily screening recycled paper products is arranged on the inner top wall of the feeding box 1, a recycling box 5 is placed on the inner bottom wall of the feeding box 1, a processing device 6 for facilitating the recycling and reuse of paper products is arranged on the inner top wall of the processing box 2, a conveying mechanism 7 for transporting paper products is arranged on the inner front wall of the feeding box 1 and located below the pretreatment component 4, an air supply component 8 penetrating through the right side wall of the processing box 2 and communicated with the inner cavity of the processing box 2 is arranged on the right side of the processing box 2, a blocking door 9 is movably connected to the left side wall of the processing box 2, and the blocking door 9 is used to block the processing box 2 to ensure that the paper products will not enter the discharging box 3 before being crushed. An arc-shaped table 10 and two collection boxes 11 are fixedly arranged on the inner bottom wall of the discharging box 3 from right to left in sequence. The arc-shaped table 10 cooperates with the air supply component 8 to ensure that the fragments can fly up smoothly, and the two collection boxes 11 are used for separate collection by using the characteristics of different gravities of long fibers and short fibers. A movable door 12 is movably connected to the inner rear wall of the discharging box 3, and a bolt 13 is inserted into the left side of the feeding box 1. The bolt 13 is used to improve the stability of the movable door 12.

[0023] In addition, the preprocessing component 4 includes a camera module 401 fixed to the inner top wall of the feeding box 1. The camera module 401 can be selected as SPECIM FX50. A moving part 402 is provided on the inner top wall of the feeding box 1 on the right side of the camera module 401. A cylinder 403 is fixed to the bottom of the moving part 402. The cylinder 403 is used to push the pneumatic gripper 404 to move the pneumatic gripper 404 downward. The bottom of the cylinder 403 is fixed with the pneumatic gripper 404. Electromagnets 405 are fixed on both the left and right sides of the pneumatic gripper 404. When the cylinder 403 pushes the pneumatic gripper 404 downward, the paper products can be grabbed, and the electromagnets 405 are used to adsorb iron products or paper products with iron, thereby effectively protecting the processing device 6.

[0024] It should be further noted that the moving part 402 includes two stabilizing plates 4021 fixed to the inner top wall of the feeding box 1. The front side of the stabilizing plate 4021 located at the rear is rotatably connected to a threaded rod 4022 passing through the stabilizing plate 4021 at the front through a bearing. The bearing can improve the rotational stability of the threaded rod 4022.

[0025] In this embodiment, the servo motor drives the threaded rod 4022 to rotate continuously. With the limiting effect of the limiting rods 4023, the continuous and stable movement of the moving block 4024 is ensured, so as to ensure that the pneumatic gripper 404 can smoothly grab the paper products.

[0026] Please refer to again Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6, in order to improve the reuse effect of paper products, the processing device 6 in this embodiment includes a dust-proof shell 601 fixed to the inner top wall of the processing box 2. A driving motor 602 is fixed to the inner top wall of the processing box 2 and inside the dust-proof shell 601. The driving motor 602 can provide continuous and stable driving force for the rotating shaft 603. The output shaft of the driving motor 602 penetrates the bottom wall of the dust-proof shell 601 and is fixed with a rotating shaft 603. A sealing bearing is fixed to the outer side of the output shaft of the driving motor 602. The output shaft of the driving motor 602 is rotatably connected to the dust-proof shell 601 through the sealing bearing. The dust-proof shell 601 can effectively protect the dust-proof shell 601. An expansion mechanism 604 extending outside the rotating shaft 603 is provided inside the rotating shaft 603. A plurality of fixed knives 605 are fixed to the outer surface of the rotating shaft 603. The fixed knives 605 are used for cutting paper products. A spiral knife 606 is fixed to the outer surface of the rotating shaft 603 and below the expansion mechanism 604. In addition to cutting paper products, the spiral structure of the spiral knife 606 itself can ensure that the paper product fragments are brought to the upper part when the spiral knife 606 rotates.

[0027] Furthermore, the telescopic mechanism 604 includes a double-axis motor 6041 fixed to the inner side wall of the rotating shaft 603. The double-axis motor 6041 can control two driving rods 6042 respectively, so as to achieve the effect of independently controlling the telescopic knife 6046. Both ends of the double-axis motor 6041 are fixed with driving rods 6042 that are rotatably connected to the rotating shaft 603 through bearings. The outer side of each driving rod 6042 is fixed with a rotating roller 6043. When the rotating roller 6043 rotates, it can cause the pull rope 60410 to be wound or gradually released. The rotating shaft 603 The outer surface of 03 is fixedly connected with a plurality of fixed seats 6044, and the inner side of each fixed seat 6044 is movably connected with a retractable knife 6046. A support spring 6045 is abutted on the side of each retractable knife 6046 close to the rotating shaft 603. When the rotating roller 6043 rotates to release the pull rope 60410, the retractable knife 6046 can be ejected due to the action of the support spring 6045. Each support spring 6045 is located in the fixed seat 6044. A clearance hole is opened on the top and bottom of each retractable knife 6046, and the clamping block 6047 can move in the clearance hole, and each clearance hole is movably connected with a clamping block 6047 extending into the fixed seat 6044. When the telescopic knife 6046 moves to a suitable position, the clamping block 6047 can be smoothly clamped into the fixed seat 6044 under the action of two compression springs 6048, so as to fix the telescopic knife 6046. The compression spring 6048 is abutted on the opposite side of each two clamping blocks 6047, and a stabilizing groove is provided on the side of each telescopic knife 6046 close to the support spring 6045. A branch rope 6049 extending into the stabilizing groove is fixed on the opposite side of each clamping block 6047. When the rotating roller 6043 pulls the pull rope 60410, the pull rope 60410 will pull the branch rope 6049, prompting the branch rope 6049 to drive the clamping block 6047 to move, thereby unlocking the retractable knife 6046. A pull rope 60410 is fixed on the side of every two branch ropes 6049 away from the clamping block 6047, and each pull rope 60410 passes through the side wall of the rotating shaft 603 and is wrapped around the outer surface of the rotating roller 6043.

[0028] In addition, the conveying mechanism 7 includes an active rod 701 and a driven rod 702 which are rotatably connected to the inner front wall of the feed box 1 through bearings. The output motor can continuously provide power for the rotation of the active rod 701. The inner rear wall of the feed box 1 is fixed with an output motor, and the output shaft of the output motor is fixed to the active rod 701. Conveying wheels are fixed on the outer surfaces of the active rod 701 and the driven rod 702. When the active rod 701 drives the conveying wheel to rotate, it will drive the conveyor belt to move. At this time, the paper products can be ensured to move smoothly. The outer surface of the conveying wheel is sleeved with a conveyor belt. The two conveying wheels transmit power through the conveyor belt. The driven rod 702 uses the conveying wheel on its outer surface mainly to provide support for the conveyor belt.

[0029] It can be known that the air supply component 8 includes an air pump 801 fixed to the right side wall of the processing box 2, and the air pump 801 is used to provide power for gas circulation. The bottom of the air pump 801 is fixedly connected to an exhaust pipe 802 extending into the right side wall of the processing box 2. The exhaust pipe 802 can provide a stable path for gas circulation. The left side of the exhaust pipe 802 is fixedly connected to a nozzle flush with the right wall of the processing box 2 and connected to the inner cavity of the processing box 2. The gas is sprayed out through the nozzle, causing the crushed paper product fragments to enter the discharge box 3. A discharge hole connected to the discharge box 3 is provided on the left side of the processing box 2, and a clearance groove connected to the discharge hole is provided on the left side wall of the processing box 2 and above the discharge hole. An electric push rod is fixed to the inner top wall of the clearance groove, and the bottom of the electric push rod is fixed to the blocking door 9. The blocking door 9 is pushed up and down by the electric push rod, and the blocking door 9 extends into the clearance groove.

[0030] In addition, the left sides of the feed box 1 and the discharge box 3 are both open, and movable grooves are provided on the front and rear side walls of the inner cavity of the processing box 2. The movable grooves can provide stable sliding of the movable door 12. A handle is fixed on the left side of the movable door 12, and the user can easily pull the movable door 12 up and down by holding the handle. Each movable groove extends into the side wall of the feed box 1, and the front and rear sides of the movable door 12 extend into the two movable grooves respectively and are movably connected with the movable grooves. A fixed groove is provided on the top of the feed box 1. When the movable door 12 moves into the fixed groove, the movable door 12 can be fixed by inserting the pin 13 into the fixing hole. The fixing groove is connected to the two movable grooves, and the pin 13 passes through the fixed groove. A fixing hole compatible with the pin 13 is provided on the movable door 12.

[0031] In this embodiment, the movable door 12 can ensure that one side of the feed box 1 or the discharge box 3 is in a closed state. When it is necessary to take materials, the movable door 12 is pulled upward, and then the latch 13 is inserted to complete the fixation of the movable door 12. At this time, the user can take out the processed materials. At the same time, the blocking effect of the movable door 12 can improve the overall safety.

[0032] It can be understood that the paper products can be preliminarily screened through the pretreatment component 4, and then the cutting degree is controlled through the processing device 6, thereby effectively reducing the excessive cutting of long fibers, facilitating subsequent recycling and reuse, and improving the utilization effect.

[0033] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the present invention is controlled by the controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0034] The working principle of the above embodiment is: (1)During use, first place the paper products on the conveying mechanism 7 in the feeding box 1. When the paper products are moving, the camera module 401 identifies the paper products. When a paper product that needs to be sorted out is identified, the output motor is started to drive the rotation of the threaded rod 4022. With the limitation of the two limiting rods 4023 on the moving block 4024, the moving block 4024 is urged to drive the pneumatic gripper 404 on the cylinder 403 to move. Through the cooperation of the pneumatic gripper 404 and the electromagnet 405, paper products such as milk cartons that cannot be directly crushed are removed. At the same time, the electromagnet 405 can suck out the paper products with iron or the iron mixed in the paper products.

[0035] (2)When multiple paper products are mixed together, the camera module 401 identifies and judges whether there are more long-fiber paper products or short-fiber paper products. When there are more long-fiber paper products, the rotating roller 6043 on the driving rod 6042 is driven to rotate by the double-shaft motor 6041, and the pulling rope 60410 is wound around the rotating roller 6043. At this time, the pulling rope 60410 will pull the branch rope 6049, prompting the clamping block 6047 to move into the retractable knife 6046. The retractable knife 6046 is retracted into the fixed seat 6044 by the pulling rope 60410 to prevent excessive crushing of long fibers due to too many blades. After the crushing is completed, the electric push rod prompts the blocking door 9 to move upward. At the same time, the air pump 801 on the air supply component 8 blows the crushed fragments into the discharge box 3. The fragments are made to fly up by the arc-shaped table 10. Since the long fibers and short fibers have different weights, most of the long fibers will fall into the collection box 11 near the arc-shaped table 10, while most of the short fibers will fall into another collection box 11, realizing the preliminary separation of long fibers and short fibers, which is convenient for subsequent reprocessing and utilization.

[0036] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made in these embodiments without departing from the principles and spirit of the present invention.
