Description

Technical Field

[0001] The present invention relates to the technical field of packaging carton processing, and particularly to a waste crushing and recycling device for packaging carton processing. Background Art

[0002] Packaging cartons are essential items in daily life, playing an indispensable role in transportation, storage, and encapsulation. During the process of processing and crushing packaging cartons, mechanical crushing is usually adopted. After crushing the cartons into flocculent shapes, they are recycled or processed secondary.

[0003] In the existing processing and crushing of packaging cartons, the cartons are usually put into the crushing machine one by one, and then the crushed carton pieces are crushed secondary until the carton pieces become flocculent. Then, the flocculent carton debris is recycled. During this period, there are some problems. For example, the initial state of the cartons can be wet or dry. Therefore, when crushing, the wet pieces will stick to the inner wall or stick to the dry pieces, which will affect the subsequent flocculent processing. Secondly, in the existing carton processing, due to the fluffy and water-absorbing nature of the flocculent carton debris, it is difficult to transport and store for a long time. Therefore, we propose a waste crushing and recycling device for packaging carton processing. Summary of the Invention

Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. 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.

[0020] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes a waste crushing and recycling device for processing packaging cartons.

[0021] In a typical embodiment of the present application, as Figures 1-9 shown, a waste crushing and recycling device for processing packaging cartons includes a crushing box 1; Before use, it should be noted that the first crushing roller 15 inside the crushing box 1 is connected to a motor. The first crushing roller 15 and the second crushing roller 16 cooperate with each other to crush the cardboard box into pieces. Users can adjust the adjusting component 2 according to their needs to obtain cardboard box pieces of the size that meets the actual requirements. At the same time, in the crushing barrel 6, the crushing barrel 6 is an existing technology. The main function of the crushing barrel 6 is to further crush the cardboard box pieces into a flocculent state and discharge them from the rectangular fixing block 54 at its bottom. When passing through the rectangular fixing block 54, the extrusion component 5 will work synchronously. The main function of the extrusion component 5 is to dry and extrude the flocculent cardboard box debris, and its purpose is to facilitate long-term transportation and storage.

[0022] As a preferred implementation manner in this embodiment, the above-mentioned adjusting component 2 includes four groups of fixing blocks 21 symmetrically fixed on the left and right sides of the outer wall of the crushing box 1. Two groups of fixing blocks 21 on one side are each rotatably connected to a bidirectional lead screw 22. The outer wall of the bidirectional lead screw 22 is symmetrically threadedly connected to two groups of threaded blocks 23. A first transmission wheel 17 is coaxially fixed to the right outer wall of the bidirectional lead screw 22 located at the front side, and a second transmission wheel 18 is coaxially fixed to the right outer wall of the bidirectional lead screw 22 located at the rear side. The second transmission wheel 18 is connected to the first transmission wheel 17 through a transmission belt 19. A first motor 13 is fixed to the right outer wall of the crushing box 1, and the output end of the first motor 13 is fixed to the first transmission wheel 17. Two groups of first stoppers 20 are symmetrically fixed on the front and rear outer walls of the crushing box 1. A hole for the bidirectional lead screw 22 to pass through is opened on the outer wall of the first stopper 20. The first crushing roller 15 is rotatably connected to the center of the inner wall of the crushing box 1, and two groups of second crushing rollers 16 are symmetrically rotatably connected to both sides of the first crushing roller 15 on the inner wall of the crushing box 1. One of the second crushing rollers 16 on the left side is rotatably connected between the two groups of threaded blocks 23 on the left side, and one of the second crushing rollers 16 on the right side is rotatably connected between the two groups of threaded blocks 23 on the right side. Four groups of chutes 29 are symmetrically opened on the front and rear outer walls of the crushing box 1. An inlet 31 is opened on the right outer wall of the crushing box 1. The four groups of threaded blocks 23 are slidably arranged on the inner wall of the chute 29. A feeding trough 12 is fixed to the right outer wall of the inlet 31. A through groove 30 is opened at the bottom of the crushing box 1, and the bottom outer wall of the through groove 30 is fixed to the trapezoidal discharge chute 27. Two groups of inclined plates 24 are symmetrically fixed to the bottom of the inner wall of the crushing box 1; Specifically, after the staff puts the carton into the crushing box 1 through the feeding chute 12, the first crushing roller 15 will start. At the same time, if the crushed carton fragments meet the user's requirements, the adjusting component 2 will not start at this time. If the user wants to obtain relatively larger or smaller carton fragments, the first motor 13 is started at this time, and two groups of bidirectional lead screws 22 are driven to rotate through the first transmission wheel 17 and the second transmission wheel 18. Note that there are four groups of threaded blocks 23 arranged on the surface of the bidirectional lead screw 22. The main function of the threaded block 23 is to drive the second crushing roller 16 to move. It should be noted here that the displacement of the second crushing roller 16 will not be a large displacement because the second crushing roller 16 is inside the crushing box 1 and will be restricted by the internal dimensions of the crushing box 1. Therefore, the maximum displacement distance of the second crushing roller 16 is that the cutter of the second crushing roller 16 just touches the inner wall of the crushing box 1. When the user adjusts the required distance, the first motor 13 is turned off at this time, and the inside of the crushing box 1 will work normally. The crushed material will enter the screening component 3 through the trapezoidal discharge chute 27 and undergo subsequent processing.

[0023] Further, in the above solution, the screening component 3 includes a first fixing plate installed on the opposite sides of four first support columns 7. Two first conveying wheels 40 are symmetrically installed on the inner wall of the first fixing plate. A second fixing plate is fixed on the top of the first fixing plate. Two second conveying wheels 41 are symmetrically installed on the inner wall of the second fixing plate. The top of the bottom of the crushing box 1 near the second fixing plate is fixed with a trapezoidal discharge chute 27. A fourth connecting pipe 37 is installed on the left side of the trapezoidal discharge chute 27. A first discharge chute 14 is installed on the right side of the trapezoidal discharge chute 27. The two first conveying wheels 40 are symmetrically rotatably connected to the inner wall of the first fixing plate. The two second conveying wheels 41 are symmetrically rotatably connected to the inner wall of the second fixing plate. The two first conveying wheels 40 are connected by a second conveyor belt 43. The two second conveying wheels 41 are connected by a first conveyor belt 42. The bottom of the trapezoidal discharge chute 27 is provided with a second discharge port 28. Several air holes 25 are provided on the left side of the trapezoidal discharge chute 27. A first discharge port 26 is provided on the right side of the trapezoidal discharge chute 27. The several air holes 25 are fixedly connected to the fourth connecting pipe 37. The outer wall of the right side of the first discharge port 26 is fixedly connected to the first discharge chute 14. A second baffle 39 is fixed on the right side of the first fixing plate. A first baffle 38 is fixed on the right side of the second fixing plate. A driving device is installed on the front outer walls of the first fixing plate and the second fixing plate. The driving device includes a second motor 47 fixed on the front outer wall of the first fixing plate. The output end of the second motor 47 is fixedly connected with a second synchronous wheel 45. The second synchronous wheel 45 is coaxially fixed to the left first conveying wheel 40. The left outer wall of the second fixing plate is rotatably connected with a first synchronous wheel 44. The first synchronous wheel 44 is coaxially fixed to the left second conveying wheel 41. The first synchronous wheel 44 and the second synchronous wheel 45 are connected by a first synchronous belt 46; Furthermore, the characteristics of the crushed carton fragments themselves are relatively light. However, before crushing, individual cartons may be soaked by rain or contain moisture due to dampness. After crushing, the wet carton fragments will stick to the dry carton fragments. At this time, after falling into the trapezoidal discharge chute 27, start the air pump 11. When the air flow is accelerated to 3m - 5m / s at the output end of the air pump 11, at this time, the dry cartons will be blown to the first discharge port 26, while the wet carton fragments will fall to the first conveyor belt 42. The dry carton fragments fall from the first discharge chute 14 through the first discharge port 26 onto the second conveyor belt 43. Note that there is a transportation space between the second conveyor belt 43 and the second conveyor belt 43. When the first conveyor belt 42 transports the wet carton fragments to the drying component 4, after the drying component 4 dries the wet carton fragments, they fall into the collection box 32 together with the dry carton fragments and are transported through the discharge port 33 into the inside of the crushing barrel 6 for the next step of crushing; It should be mentioned that the second conveyor belt 43 and the first conveyor belt 42 are displaced by the drive of the second motor 47. There are a first baffle 38 and a second baffle 39 arranged near the first conveyor belt 42 and the second conveyor belt 43. Their main function is to prevent the carton fragments from flying around. At the same time, the air pump 11 is connected to the fourth connecting pipe 37 through the third connecting pipe 36, and the fourth connecting pipe 37 is connected to the air hole 25 on the left side of the trapezoidal discharge chute 27.

[0024] In this embodiment, the drying component 4 includes a drying box 34 fixed on the tops of four groups of second support columns 8. A rectangular groove 49 is opened at the top of the drying box 34. A heating box 48 is fixed on the left side of the drying box 34. A heating rod 50 is fixed on the inner wall of the rectangular groove 49. The heating box 48 is fixedly connected to the heating rod 50. A air pump 11 is fixed on the top of the drying box 34. The right end of the air pump 11 is fixedly connected to a third connecting pipe 36. The third connecting pipe 36 is fixedly connected to the fourth connecting pipe 37. The left end of the air pump 11 is fixedly connected to a second connecting pipe 35. The end of the second connecting pipe 35 far from the air pump 11 is fixedly connected to the drying box 34. A number of air outlets 51 are equidistantly fixed at the bottom of the drying box 34. A first connecting pipe 10 is fixed on the outer wall of the drying box 34 near the crushing barrel 6. The other end of the first connecting pipe 10 is fixedly connected to the crushing barrel 6; Inside the drying box 34 mentioned above, a heating rod 50 is provided, and a heating box 48 is connected to the other end thereof. The specific working principles of the heating box 48 and the heating rod 50 are existing technologies and will not be elaborated in detail here. It should be noted that a second connecting pipe 35 is provided at the top of the drying box 34, and the other end of the second connecting pipe 35 is connected to the air pump 11. The main function of this design is to convert the air output by the air pump 11 into hot air and dry the wet cardboard fragments. It should be noted that a first connecting pipe 10 is provided on the outer wall of the drying box 34 close to the crushing barrel, and the other end of the first connecting pipe 10 is connected to the extrusion assembly 5. The main function of this design is to divide part of the hot air inside the drying box 34 and transfer it to the extrusion assembly 5, which is beneficial to improving work efficiency.

[0025] Finally, the extrusion assembly 5 includes a rectangular fixing block 54 fixed to the bottom of the crushing barrel 6. Two groups of second stoppers 55 are symmetrically fixed to the outer wall of the bottom of the rectangular fixing block 54. Two groups of extrusion rollers 60 are symmetrically rotatably connected to the inner walls of the two groups of second stoppers 55. A third synchronous wheel 56 is rotatably connected to the outer wall of the second stopper 55 on the front side. A fourth synchronous wheel 57 is rotatably connected to the outer wall of the second stopper 55 on the front side near the third synchronous wheel 56. The third synchronous wheel 56 and the fourth synchronous wheel 57 are connected by a second synchronous belt 58. A third motor 59 is fixed to the outer wall of the second stopper 55 on the front side. The output end of the third motor 59 is fixedly connected to the fourth synchronous wheel 57. One extrusion roller 60 on the left is coaxially fixedly connected to the third synchronous wheel 56, and one extrusion roller 60 on the right is coaxially fixedly connected to the fourth synchronous wheel 57. A fixing ring 53 is fixed to the outer wall of the bottom of the crushing barrel 6, and four groups of third support columns 9 are equidistantly fixed to the outer wall of the fixing ring 53; It is worth mentioning that after the cardboard fragments enter the inside of the crushing barrel 6, they are further crushed. Note that this crushing is to further crush the cardboard fragments into a flocculent shape and then discharge them from the rectangular fixing block 54. At the same time, the third motor 59 is started to make the two groups of extrusion rollers 60 rotate. The rotation of the extrusion rollers 60 will extrude the flocculent cardboard debris. It should be noted that several air outlets are provided on the surface of the extrusion rollers 60, and the air outlets are connected to the first connecting pipe 10. This design can transmit hot air to the flocculent cardboard debris through the air outlets, thus forming the characteristic of extrusion and drying at the same time. The main purpose of this design is to facilitate transportation and long-term storage.

[0026] Working principle of the present invention: After the staff puts the carton into the crushing box 1 through the feeding chute 12, the first crushing roller 15 will start. At the same time, if the crushed carton pieces meet the user's requirements, the adjusting component 2 will not start at this time. If the user wants to obtain relatively larger or smaller carton pieces, the first motor 13 is started at this time, and two groups of bidirectional lead screws 22 are driven to rotate through the first transmission wheel 17 and the second transmission wheel 18. Note that four groups of threaded blocks 23 are arranged on the surface of the bidirectional lead screw 22. The main function of the threaded block 23 is to drive the second crushing roller 16 to move. It should be noted here that the displacement of the second crushing roller 16 will not be a large displacement because the second crushing roller 16 is inside the crushing box 1 and will be restricted by the internal dimensions of the crushing box 1. Therefore, the maximum displacement distance of the second crushing roller 16 is that the cutter of the second crushing roller 16 just touches the inner wall of the crushing box 1. When the user adjusts the required distance, the first motor 13 is turned off at this time, and the inside of the crushing box 1 will work normally. The crushed material will enter the screening component 3 through the trapezoidal discharge chute 27 for screening. After the carton pieces enter the crushing barrel 6, they will be further crushed. Note that this crushing is to further crush the carton pieces into a flocculent shape and then discharged by the rectangular fixing block 54. At the same time, the third motor 59 is started to make the two groups of extrusion rollers 60 rotate. The rotation of the extrusion rollers 60 will extrude the flocculent carton debris. It should be mentioned that several air outlets are arranged on the surface of the extrusion roller 60, and the air outlets are connected to the first connecting pipe 10. This design can transmit hot air to the flocculent carton debris through the air outlets, thus forming the characteristic of extrusion and drying at the same time. The main purpose of this design is to facilitate transportation and long-term storage.

[0027] 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.
