Description

Technical Field

[0002] Cardboard boxes possess mechanical properties such as light weight, compression resistance, puncture resistance, tear resistance, cushioning, shock resistance, and easy processing and forming. They also have good suitability for decoration and printing, can be recycled, and do not pollute the environment after disposal. As living standards improve, people's food becomes more abundant. However, cardboard boxes are often bound with tacks as needed, and the inside of the cardboard box contains tacks and other metal objects. This can easily cause certain dangers during subsequent cleaning and is not convenient for later recycling. For example, Chinese invention patent with patent publication number CN205276035U solves the problems of paper-metal separation device and paper-plastic separation.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1

[0037] Please see Figures 1-11As shown, this invention is a recycling and processing device for waste cardboard boxes, including a recycling bin 1. A transport platform 2 with a support plate 3 is fixedly installed inside the recycling bin 1. A separation component 4 is provided on the transport platform 2. The separation component 4 includes a metal detector 416 fixedly installed on the transport platform 2. The metal detector 416 is electrically connected to an electric telescopic rod 42. When the metal detector 416 detects metal, it activates the electric telescopic rod 42, causing it to drive a cutting blade 410 via a moving plate 43 to cut the metal off the cardboard box. The cardboard box is then crushed, minimizing damage to the cutting blade during the crushing process. A mounting plate 41 with the electric telescopic rod 42 is fixedly installed on the top of the recycling bin 1. Two cutting blades 410 are fixedly installed on one end of the electric telescopic rod 42 near the transport platform 2. The movable plate 43 of the 10 and the cutting blade 410 are used to cut the metal parts on the carton. The movable plate 43 has a movable groove 48 on the side near the conveyor table 2. A stirring plate 411 for moving the metal is slidably installed in the movable groove 48. The stirring plate 411 makes it easy to squeeze and push the cut metal parts into the water tank 413. The stirring roller 414 stirs and dissolves the waste paper scraps on the metal, which facilitates the collective recycling of the metal. The movable plate 43 is equipped with a winding unit. Two fixed plates 44 are fixedly installed on the side of the movable plate 43 near the electric telescopic rod 42. A winding roller 45 is rotatably installed between the two fixed plates 44. The winding roller 45 plays the role of winding the winding rope 47 under the drive of the first motor 46. The first motor 46 is fixedly installed on the side of one of the fixed plates 44 away from the winding roller 45. The winding rope 47 is fixedly installed on the winding roller 45.

[0038] A guide rod 49 is slidably mounted on the actuating plate 411. Both ends of the guide rod 49 are fixedly mounted on the inner wall of the moving groove 48. The guide rod 49 serves to guide and limit the actuating plate 411. The other end of the winding rope 47 slidably passes through the moving groove 48 and is fixedly mounted on the actuating plate 411. A first spring 412 is fixedly mounted on the side of the actuating plate 411 away from the winding rope 47. The other end of the first spring 412 is fixedly mounted on the inner wall of the moving groove 48. The first spring 412 is nested on the outer surface of the guide rod 49. The first spring 412 serves to elastically reset the actuating plate 411. The actuating plate 411 is fixedly mounted between two cutting blades 410. The output end of the first motor 46 slidably passes through a fixed plate 44 and is fixedly mounted on the winding roller 45. A metal detector 416 is fixedly mounted between the two cutting blades 410, facilitating the cutting of the detected cardboard boxes by the cutting blades 410, and allowing for the separation of cardboard boxes and metal parts. The separation and recycling process involves a cutting blade 410 fixedly installed on the side of the moving plate 43 away from the electric telescopic rod 42. A water tank 413 is formed between the support plate 3 and the inner wall of the recycling box 1. An agitating roller 414 is rotatably installed in the water tank 413. The agitating roller 414 agitates the metal containing waste paper scraps in the water tank 413, facilitating the dissolution of waste paper scraps in the water and making it easier to classify and recycle the metal and waste paper scraps. A second motor 415 is fixedly installed on one side of the recycling box 1. The output end of the second motor 415 slides through the recycling box 1 and is fixedly installed on the agitating roller 414, facilitating the separation and recycling of metal on the cardboard box before it is broken. This minimizes the need for manual metal sorting and separation, reduces the risk of damage to broken parts due to metal, and facilitates centralized metal recycling. This process also helps extend the service life of the device, improves the efficiency of the separation and recycling process, and enhances the safety of the device.

[0039] Example 2

[0040] Please see Figure 2 , Figure 7 , Figure 8 , Figure 10 and Figure 11As shown, based on Embodiment 1, a crushing assembly 5 is provided on the transport platform 2. The crushing assembly 5 includes a conveyor belt 513 rotatably mounted on the transport platform 2, which carries the transport cartons. Two crushing rollers 514 are rotatably mounted on the end of the conveyor belt 513 away from the metal detector 416. The relative movement of the crushing rollers 514 crushes the cartons. Two pulleys 510 are rotatably mounted on one side of the transport platform 2, and a second pulley 512 is installed between the two pulleys 510. A third motor 511 is fixedly mounted on the side of the pulleys 510 away from the transport platform 2. The output end of the third motor 511 is fixedly mounted on one of the pulleys 510. Two gears 59 are rotatably mounted on one side of wheel 510. The two gears 59 mesh with each other. The rotating shafts of the two gears 59 slide through the conveyor table 2 and are fixedly mounted on the rotating shafts of the two crushing rollers 514, driving the two crushing rollers 514 to move relative to each other for crushing operation. The rotating shaft of one pulley 510 slides through the conveyor table 2 and is fixedly mounted on the drive shaft of the conveyor belt 513. The rotating shaft of the other pulley 510 slides through the conveyor table 2 and is fixedly mounted on the rotating shaft of the lower crushing roller 514. The conveyor belt 513 and the lower crushing roller 514 move in the same direction. The lower crushing roller 514 and the upper crushing roller 514 move in opposite directions, which facilitates the crushing operation.

[0041] Two protective plates 51 are fixedly installed on the side of the transport platform 2 away from the support plate 3. The conveyor belt 513 prevents the cartons from falling into the water tank 413. A connecting plate 52 is fixedly installed on the side of the protective plate 51 away from the transport platform 2. Multiple dividing blades 53 are fixedly installed on the side of the connecting plate 52 near the conveyor belt 513. The dividing blades 53 divide the cartons before crushing. A sliding rod 56 is slidably installed through the connecting plate 52. The sliding rod 56 limits and stabilizes the squeezing plate 54. The squeezing plate 54 is fixedly installed at the end of the sliding rod 56 near the conveyor belt 513. A second spring 57 is fixedly installed between the squeezing plate 54 and the connecting plate 52. The elasticity of the second spring 57 is... The resetting force drives the squeezing plate 54 to squeeze and stabilize the carton, facilitating the transport operation of the conveyor belt 513. A guide plate 55 is fixedly installed on the side of the squeezing plate 54 away from the dividing knife 53. The guide plate 55 guides the movement of the carton toward the dividing knife 53, which helps to improve the guiding ability of the device. The second spring 57 is nested on the outer surface of the slide rod 56. A limit plate 58 is fixedly installed on the end of the slide rod 56 away from the squeezing plate 54. The limit plate 58 limits and stabilizes the slide rod 56, which facilitates the crushing operation of the carton with the metal cut off. It also facilitates pre-segmentation before crushing to facilitate the crushing operation, which helps to improve the crushing capacity of the device and improve the crushing efficiency of the device.

[0042] Example 3

[0043] Please see Figure 1 , Figure 3 and Figure 4 As shown, based on Embodiments 1 and 2, a compression assembly 6 is provided on the support plate 3. The compression assembly 6 includes a groove 61 on the side of the support plate 3 away from the agitator roller 414. A bidirectional screw 66 is rotatably installed in the groove 61. Two sliders 62 are threaded through the bidirectional screw 66. A rotating plate 63 is rotatably installed on the side of the sliders 62 away from the agitator roller 414. The bidirectional screw 66 drives the rotating plate 63 through the compression plate 64 to push the compression plate 64 to squeeze the crushed waste paper scraps, which facilitates secondary shaping of the waste paper scraps and facilitates subsequent stacking and transportation operations. A compression plate 63 is rotatably installed on the end of the two rotating plates 63 away from the sliders 62. 4. A fourth motor 67 is fixedly installed on the side of the recycling box 1 near the second motor 415. The output of the fourth motor 67 slides through the recycling box 1 and the chute 61 and is fixedly installed on the bidirectional screw 66. An elastic band 65 rotates on the side of the compression plate 64 near the conveyor table 2. The other end of the elastic band 65 is fixedly installed on the support plate 3. The elastic band 65 can be stretched with the movement of the compression plate 64, which plays the role of receiving the fragments, making it easier for the crushed waste paper to be reshaped, and facilitating subsequent stacking and transportation operations. It is convenient for stacking and extrusion molding, which helps to improve the working efficiency of the device and the ability of the device to compress waste paper.

[0044] The working principle of this invention is as follows: When using the device, first, water is poured into the water tank 413, and then the cardboard from the disassembled carton is placed on the transport platform 2 inside the recycling bin 1. When the cardboard passes the metal detector 416 and metal is detected, the metal detector 416 controls the electric telescopic rod 42 to move downwards. At the same time, the electric telescopic rod 42 drives the cutting blade 410 on the moving plate 43 to move to the transport platform 2, facilitating the cutting of the cardboard on the transport platform 2. Then, the first motor 46 is started, and the output end of the first motor 46 drives the winding roller 45, causing the winding roller 45 to rotate and wind up the winding rope 47. The winding rope 47 then drives the actuating plate 411 to move. The first spring 412 slides within the groove 48, simultaneously causing the actuating plate 411 to slide on the guide rod 49, stretching the first spring 412. This puts the first spring 412 in a stretched state, and simultaneously causes the actuating plate 411 to push the cut cardboard containing metal into the water tank 413. Then, the second motor 415 is activated to drive the agitating roller 414 to agitate and remove the waste paper containing metal. Next, the electric telescopic rod 42 drives the cutting blade 410 to return to its original position, causing the elasticity of the first spring 412 to elastically reset the actuating plate 411. Simultaneously, the third motor 511 is activated, causing its output to drive one of the pulleys 510 to rotate, thus causing one of the pulleys... The pulley 510 drives another pulley 510 to rotate via the second pulley 512. Simultaneously, the two pulleys 510 drive the conveyor belt 513 and the lower crushing roller 514 to rotate synchronously. The lower crushing roller 514, through two meshing gears 59, drives the other crushing roller 514 to rotate, causing the two crushing rollers 514 to move relative to each other. At the same time, the conveyor belt 513 moves the cardboard towards the guide plate 55. Under the action of the guide plate 55, the cardboard drives the pressure plate 54 to press against the second spring 57 and the slide bar 56, causing the slide bar 56 to slide on the connecting plate 52. Simultaneously, the second spring 57 is in a compressed state, and the conveyor belt 51... 3. The cardboard moves towards the dividing knife 53, and then moves to the two crushing rollers 514 for crushing. The crushed waste paper scraps fall into the recycling bin 1 through the elastic belt 65. Then, the fourth motor 67 is started, and the output end of the fourth motor 67 drives the bidirectional screw 66 to rotate in the slide groove 61. At the same time, the bidirectional screw 66 drives the two sliders 62 to move relative to each other. Simultaneously, the sliders 62 drive the rotating plate 63 to push out the compression plate 64 to squeeze the waste paper scraps. At the same time, the compression plate 64 pulls the elastic belt 65 and compresses the waste paper scraps. Finally, the water in the water tank 413 is drained, and the metal is collected.

[0045] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
