Description

Technical Field

[0001] The present invention relates to the field of carton waste treatment equipment, and particularly to a waste treatment equipment for processing waste generated from packaging cartons. Background Art

[0002] As a kind of packaging carton, corrugated cartons are widely used in the packaging and transportation protection of various commodities due to their high strength, good cushioning performance, and low cost. Their surfaces are often covered with PE films to enhance the moisture-proof and waterproof capabilities of the cartons, and at the same time improve the durability and applicability of the cartons.

[0003] The PE film is a kind of polymer material with a dense structure and hydrophobicity, which can effectively isolate the penetration of liquid water and water vapor, preventing the cartons from becoming soft, deformed or losing strength after being exposed to moisture. After the PE film is covered, the surface of the cartons is not easily adsorbed with dust and stains, keeping the packaging appearance clean. At the same time, it can reduce the surface damage of the cartons caused by friction and collision during transportation, and extend the service life of the cartons.

[0004] During the recycling process of cartons, the cartons are placed in a crusher (such as a hammer crusher), and the high-speed rotating hammer heads impact, shear and rub the cartons to break them down

[0005] into small pieces or fibrous materials. This waste treatment method only recycles the cartons and it is difficult to separate and recycle the PE films covered on the cartons.

Detailed implementation manners

[0028] Next, a specific embodiment of the present invention will be elaborated in detail with reference to the accompanying drawings.

[0029] Refer to the attached Figure 1- Figure, a waste treatment device for processing packaging cartons, including a waste treatment frame 111. A front support seat 5 and a rear support seat 51 are fixedly connected to the front and rear of the waste treatment frame 111 respectively. A carton crushing area and a PE film recycling area are provided on the waste treatment frame 111. A transportation component is arranged between the front support seat 5 and the rear support seat 51 to transport the cartons to be crushed to the crushing area of 111 for crushing treatment. To facilitate the transportation of cartons, this device is realized by setting a conveyor belt 7. Specifically: A first rotating shaft 6 is rotatably connected to the front support seat 5, and a second rotating shaft 701 is rotatably connected to the rear support seat 51. Two conveyor belts 7 are parallelly wound between the first rotating shaft 6 and the second rotating shaft 701. That is, the cartons to be processed are placed on the conveyor belt 7 and transported to the crushing area through the conveyor belt 7. To realize the transportation action of the conveyor belt 7, one end of the first rotating shaft 6 is fixedly connected to a power source asynchronous motor 61. By starting the asynchronous motor 61, the first rotating shaft 6 rotates, and the conveyor belt 7 and the second rotating shaft 701 rotate synchronously.

[0030] The cartons to be processed are placed on the conveyor belt 7 with the carton facing up and the PE film facing down. Start the asynchronous motor 61, and the conveyor belt 7 rotates, driving the cartons on it to move. According to the above, the cartons need to be recycled by mechanical crushing to reduce the volume of the cartons, and then combined with chemical treatment to remove the adhesives or printing pigments on the surface of the cartons and increase the bonding force between fibers to ensure the physical properties of the recycled paper meet the production requirements and facilitate recycling.

[0031] Common mechanical crushing methods include using spiral blades to crush or high-speed rotating hammers to strike the cartons to make them broken. However, according to what is described in the background technology, as a kind of packaging carton, the corrugated carton usually has a large thickness, and the thickness of the carton mainly comes from the internal wavy corrugated core layer, which can significantly improve the compressive, buffering and supporting properties of the cardboard. According to the above conventional methods, the crushing efficiency is not high and the energy consumption is large. To combine the crushing action and the chemical treatment action, this device adopts the following method: A guiding support frame 11 is fixedly connected to the waste treatment frame 111. A rolling member 14 for initially crushing the cartons is provided on the guiding support frame 11. A crushing component is provided on the rolling member 14, aiming to initially crush the cartons through the pressure of the rolling member 14 and the crushing component on it. To facilitate the installation and stability of the rolling member 14, specifically: A pin 13 is provided on the guiding support frame 11, and a fixing member 12 is clamped to the guiding support frame 11 through the pin 13. The fixing member 12 is fixedly connected to both ends of the rolling member 14, aiming to facilitate the installation and stability of the rolling member 14 on the support frame 11 through the pin 13 and the fixing member 12.

[0032] The rolling part 14 is a hollow pipe, which means that a chemical solution can be poured into the rolling part 14. The main components of the chemical solution are sodium hydroxide and vinyl alcohol. A plurality of hollow conical parts 15 are fixedly connected to the rolling part 14. The hollow conical parts 15 communicate with the inner cavity of the rolling part 14, aiming to allow the chemical solution in the rolling part 14 to flow into the inner cavity of the hollow conical parts 15. A discharge groove 152 is formed on the hollow conical part 15. A telescopic part 16 is slidably connected in the hollow conical part 15. A hollow cavity is provided in the telescopic part 16. The telescopic part 16 is a cone and a discharge hole 162 is provided at the tip. A groove 161 is also provided on the telescopic part 16. A linear spring 17 is compressed between the telescopic part 16 and the hollow conical part 15, aiming to make the groove 161 on the telescopic part 16 and the discharge groove 152 on the hollow conical part 15 be misaligned by the linear spring 17 when no extrusion occurs.

[0033] In this preliminary crushing process, holes are punched in the cardboard box by the tip of the telescopic part 16, and at the same time, the chemical solution in the hollow conical part 15 is injected into the cardboard box through the tip of the telescopic part 16. The chemical solution can directly penetrate into the interior of the cardboard through the holes quickly, avoiding the hindrance of the waterproof coating on the surface of the cardboard to penetration, shortening the reaction time at the same time. Traditional soaking takes several hours, but only a few minutes are needed after punching holes. It also reduces the targeted injection of chemical solution, avoids waste of a large amount of solution, and improves the subsequent further crushing and separation work.

[0034] To facilitate the installation and stability of the telescopic part 16 in the hollow conical part 15, a limit nut 151 is provided on the outer wall of the hollow conical part 15. The limit nut 151 contacts the telescopic part 16, aiming to prevent the telescopic part 16 from falling off the hollow conical part 15. When installing, just remove the limit nut 151.

[0035] Under the transmission of the conveyor belt 7, the cardboard box is transported to the lower part of the rolling part 14. The tip of the telescopic part 16 first contacts the cardboard box, and as the cardboard box moves, it drives the rolling part 14 to rotate. An extrusion force will be generated between the cardboard box and the telescopic part 16 in contact with the cardboard box. The telescopic part 16 moves upward under extrusion, the linear spring 17 deforms, the groove 161 on the telescopic part 16 and the discharge groove 152 on the hollow conical part 15 are communicated, and then the chemical solution in the hollow conical part 15 smoothly enters the inner cavity of the telescopic part 16 and flows into the interior of the cardboard box through the discharge hole 162 of the telescopic part 16. The telescopic part 16 that does not contact the cardboard box is not extruded and the groove 161 on the telescopic part 16 and the discharge groove 152 on the hollow conical part 15 remain misaligned, and the solution in the hollow conical part 15 cannot be discharged, thus avoiding waste of chemical solution.

[0036] Special note: In the above preliminary crushing process, the cardboard box has a certain thickness. The telescopic part 16 on the rolling part 14 only contacts and extrudes the cardboard box and will not penetrate the cardboard box and act on the PE film.

[0037] After the cardboard box is initially crushed, the cardboard box is gradually softened after being infiltrated with a chemical solution, and then can be further crushed and separated. Therefore, this device is realized by setting a crushing pool 1 on the waste treatment rack 111. A crushing pool 1 is fixedly connected to the waste treatment rack 111. The inner lining of the crushing pool 1 is made of wear-resistant polymer material. The crushing pool 1 is placed at the bottom of the conveyor belt 7. Symmetrically distributed crushing chambers 1011 are provided in the crushing pool 1. The crushing chambers 1011 are distributed at the bottom of the conveyor belt 7. A chemical solution is placed in the crushing chambers 1011. A plurality of third rotating shafts 201 are also rotatably connected in the crushing chambers 1011. Crushing rollers 2 for further crushing the cardboard box are fixedly connected to the third rotating shafts 201. A plurality of toothed impellers are provided on the crushing rollers 2, aiming to generate eddy currents to shear the cardboard box through the high-speed rotation of the toothed impellers of the crushing rollers 2. To achieve the high-speed rotation of the crushing rollers 2, this device makes the following settings: The output end of a servo motor 4 is fixedly connected to the third rotating shaft 201. By starting the servo motor 4, the third rotating shaft 201 can be driven to rotate, thereby realizing the high-speed rotation of the toothed impellers.

[0038] Heat-conducting frames 142 are fixedly connected in the crushing chambers 1011. Heating elements are installed on the heat-conducting frames 142, aiming to heat the chemical solution in the crushing chambers 1011 through the heating elements on the heat-conducting frames 142, improve the decomposition rate, and shorten the decomposition time. Considering that the rolling members 14 are also filled with a chemical solution, to achieve the synchronous heating of the chemical solution, the following settings are made: A conveying pipe 141 is provided between the crushing chambers 1011 and the inner cavities of the rolling members 14, aiming to perform heat exchange between the crushing chambers 1011 and the inner cavities of the rolling members 14.

[0039] Of course, a plurality of third rotating shafts 201 are provided in the crushing chambers 1011. To achieve the synchronous rotation of the plurality of third rotating shafts 201, a power source can be separately provided on each third rotating shaft 201. This method has a high cost and is not advisable. Therefore, this device realizes the effect of driving a plurality of third rotating shafts 201 to rotate by only setting one power source through the method of gear linkage. Gears 3 are fixedly connected to one ends of the third rotating shafts 201. The gears 3 on adjacent two third rotating shafts 201 are meshed with each other. By starting the servo motor 4 to drive one of the third rotating shafts 201 to rotate, the gears 3 are then controlled to rotate. Through the meshing transmission of a plurality of gears 3, a plurality of third rotating shafts 201 and the crushing rollers 2 thereon are driven to rotate synchronously. As the heat-conducting frame 142 heats the chemical solution in the crushing chambers 1011, the crushing of the cardboard box in the crushing chambers 1011 can be accelerated. A discharge pipe for facilitating the discharge of materials is also provided on the crushing chambers 1011. After the cardboard box in the crushing chambers 1011 is crushed and decomposed, it can be discharged through the discharge pipe, and finally the efficient recovery of cardboard box fibers is realized.

[0035] According to the foregoing, the preliminarily crushed cartons are attached to the PE film, and the PE film is attached to the conveyor belt 7. To put the preliminarily crushed cartons into the crushing chamber 1011, a pushing power source can be set on the conveyor belt 7 to push the cartons thereon into the crushing chamber 1011. However, considering that the purpose of this device is to separate the cartons and the PE film and then process them separately, if a pushing power source is simply set on the conveyor belt 7, the cartons and the PE film will be pushed into the crushing chamber 1011 together. Therefore, in this pushing action, this device is used to push the preliminarily crushed cartons into the crushing chamber 1011, while the PE film remains on the conveyor belt 7. The following settings are made: A fixed support plate 10 is fixedly connected to the crushing pool 1. The fixed support plate 10 is placed between the two conveyor belts 7 and is in seamless contact with the side of the conveyor belt 7. The fixed support plate 10 remains stationary and is not affected by the two conveyor belts 7 on both sides. Mounting frames 18 are fixedly connected to the crushing chamber 1011. A first lead screw 20 and a second lead screw 21 are rotatably connected between the mounting frames 18. The first lead screw 20 and the second lead screw 21 are both suspended above the conveyor belt 7. A first moving frame 22 and a second moving frame 221 are respectively threadedly connected to the first lead screw 20 and the second lead screw 21. Pressing plates 24 are provided on the lower surfaces of the first moving frame 22 and the second moving frame 221. Scraping plates 25 are fixedly connected to the bottoms of the pressing plates 24. The scraping plates 25 are suspended at the central axis of the fixed support plate 10. The purpose is to drive the first moving frame 22 and the second moving frame 221 to move reciprocally by the rotation of the first lead screw 20 and the second lead screw 21, and the pressing plates 24 and the scraping plates 25 are controlled to move. Through the reciprocating movement of the scraping plates 25, the pushing action on the cartons on the conveyor belt 7 is realized. Two guide rods 19 are fixedly connected between the mounting frames 18. The guide rods 19 respectively penetrate the first moving frame 22 and the second moving frame 221, aiming to guide the movement of the first moving frame 22 and the second moving frame 221. To realize the rotation of the first lead screw 20 and the third rotating shaft 201, motors are provided at one ends of the first lead screw 20 and the second lead screw 21. Air cylinders 23 are installed on the first moving frame 22 and the second moving frame 221. The output shafts of the air cylinders 23 penetrate the first moving frame 22 and the second moving frame 221 and are fixedly connected to the tops of the pressing plates 24, aiming to adjust the height of the pressing plates 24 by starting the air cylinders 23, and further adjust the pressing height of the scraping plates 25.

[0036] The cardboard box and the PE film move along with the conveyor belt 7 and are transported under the scraper 25. After controlling the asynchronous motor 61 to stop the rotation of the first rotating shaft 6, and then the conveyor belt 7 stops moving, first start the cylinders 23 on the first moving frame 22 and the second moving frame 221 to drive the pressing plate 24 and the scraper 25 to move downward, aiming to press and fix the cardboard box and the PE film. Subsequently, start the motor on the first lead screw 20. The first lead screw 20 rotates, and the first moving frame 22 is controlled to move, thereby driving the pressing plate 24 and the scraper 25 on one side of the first moving frame 22 to move. Thus, the cardboard box on one side of the first moving frame 22 is pushed into the crushing chamber 1011 of the crushing pool 1. The pressing plate 24 and the scraper 25 on one side of the first moving frame 22 achieve the pushing action of the cardboard box, while the pressing plate 24 and the scraper 25 on one side of the second moving frame 221 maintain the downward pressing action, aiming to press the PE film on the fixed support plate 10. During the process of pushing the cardboard box on the PE film into the crushing chamber 1011 by the pressing plate 24 and the scraper 25 on one side of the first moving frame 22, the PE film and the cardboard box are separated. Subsequently, the cylinder 23 acts to lift the pressing plate 24 and the scraper 25, and the motor on the first lead screw 20 reverses, driving the first lead screw 20 to rotate in the reverse direction, thereby driving the pressing plate 24 and the scraper 25 on one side of the first moving frame 22 to move back to their original positions.

[0037] After the pressing plate 24 and the scraper 25 on one side of the first moving frame 22 move back to their original positions, the cylinder 23 acts again to drive the pressing plate 24 and the scraper 25 to move downward. Start the motor on the second lead screw 21. The second lead screw 21 rotates, and the second moving frame 221 is controlled to move, thereby driving the pressing plate 24 and the scraper 25 on one side of the second moving frame 221 to move. Thus, the cardboard box on one side of the second moving frame 221 is pushed into the crushing chamber 1011 of the crushing pool 1. The pressing plate 24 and the scraper 25 on one side of the second moving frame 221 achieve the pushing action of the cardboard box, while the pressing plate 24 and the scraper 25 on one side of the first moving frame 22 maintain the pressing action on the PE film. The PE film and the cardboard box are separated. Similar to the above, subsequently, the cylinder 23 acts to lift the pressing plate 24 and the scraper 25, and the motor on the second lead screw 21 reverses, driving the second lead screw 21 to rotate in the reverse direction, thereby driving the pressing plate 24 and the scraper 25 on one side of the second moving frame 221 to move back to their original positions.

[0038] To sum up: This pushing action alternately starts the motors on the first lead screw 20 and the second lead screw 21, causing the scraper 25 on one side to move and return to its original position, while the scraper 25 on the other side maintains the downward pressing action. Thus, the PE film is stably fixed on the fixed support plate 10, and the cardboard box on the PE film is pushed into the crushing chamber 1011 for further crushing and decomposition.

[0039] After the pushing action ends, the cardboard box falls into the crushing chamber 1011, and the PE film moves to the rear support seat 51 along with the conveyor belt 7. A collecting component for the PE film is provided on the rear support seat 51, including a guiding member 26 fixedly connected to the rear support seat 51. The guiding member 26 is connected to the end of the conveyor belt 7, aiming to smoothly transport the PE film on the conveyor belt 7 into the guiding member 26. An inclined surface that slopes downward is provided at the end of the guiding member 26 to facilitate the sliding of the PE film. A limiting rod 28 is installed on the side wall of the rear support seat 51 through a fastener. A storage basket 27 for collecting the PE film is installed on the limiting rod 28. The storage basket 27 can be installed or disassembled by removing the fastener. The storage basket 27 is located below the guiding member 26 to receive the PE film sliding down from the guiding member 26.

[0040] The PE film moves to the rear support seat 51 along with the conveyor belt 7, and then is received by the guiding member 26. The PE film falls into the storage basket 27 along the inclined surface of the guiding member 26, thus completing the collection of the PE film.

[0041] During the above process, after the cardboard box is initially crushed by the rolling member 14 and infiltrated with a chemical solution and gradually softened, there is a risk that the chemical solution remains on the PE film and the conveyor belt 7, causing the PE film to stick to the conveyor belt 7 and unable to be smoothly transferred to the guiding member 26. Therefore, the present device makes the following settings to solve this problem: A plurality of ventilation holes 29 are opened on the conveyor belt 7. An airbag 8 is installed in each ventilation hole 29. A pressure relief hole is provided on each airbag 8. The pressure relief hole of the airbag 8 is connected to the ventilation hole 29. The airbags 8 are all placed at the bottom of the conveyor belt 7 and move along with the conveyor belt 7. Extrusion blocks 9 are sleeved on both ends of the first rotating shaft 6 and the second rotating shaft 701. A connecting rod 291 is connected between the extrusion blocks 9 at both ends of each first rotating shaft 6 and the second rotating shaft 701. The two connecting rods 291 penetrate through the first rotating shaft 6 and the second rotating shaft 701 and are respectively fixed to the front support seat 5 and the rear support seat 51. The rotation of the first rotating shaft 6 and the second rotating shaft 701 does not affect the extrusion blocks 9. The extrusion block 9 is in the shape of a water droplet. The airbag 8, the ventilation hole 29, and the extrusion block 9 form a passive one-way air flow mechanism. When the external force is removed, a negative pressure is formed inside the airbag 8, and external gas enters the airbag 8. When the airbag is under external pressure, the gas inside the airbag 8 is discharged passively.

[0042] As the conveyor belt 7 moves, the airbag 8 on the conveyor belt 7 moves synchronously. The movement of the airbag 8 will generate extrusion with the extrusion block 9. The airbag 8 on one side of the front support seat 5 presents an action of first passive exhaust and then automatic inhalation with the extrusion of the water droplet-shaped surface of the extrusion block 9. Through the automatic inhalation of the airbag 8, the PE film and the cardboard box near the front support seat 5 can be adsorbed on the conveyor belt 7 to prevent them from falling. The airbag 8 on one side of the rear support seat 51 presents an action of first automatic inhalation and then passive exhaust with the extrusion of the water droplet-shaped surface of the extrusion block 9. Through the passive exhaust of the airbag 8, the gas is discharged from the ventilation hole 29 and then acts on the PE film on the conveyor belt 7. The PE film can be lifted upward by a certain distance through the airflow, preventing the PE film from sticking to the conveyor belt 7 due to the chemical solution excessively.

[0043] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
