Description

Technical Field

[0001] The invention relates to the technical field of corrugated paper box production, in particular to a scrap material crushing device for corrugated paper box production. Background Art

[0002] Corrugated boxes are rigid paper packaging containers made of hollow corrugated cardboard through die-cutting, creasing, nailing or gluing. The base paper of corrugated boxes mainly includes face paper, lining paper and core paper. The face paper and lining paper mainly play the role of protection and decoration, while the core paper is responsible for providing cushioning and support. Corrugated cardboard is the main component of corrugated boxes. Its production process includes base paper pretreatment, corrugated forming, gluing, laminating and drying. The box making process is the process of processing corrugated cardboard into boxes of various shapes and sizes. Common box making processes include die-cutting, creasing, folding and gluing.

[0003] In the process of making corrugated cardboard, die-cutting is required, that is, the corrugated cardboard is cut into the required shape and size by a die-cutting machine. In this process, scraps (i.e., corrugated cardboard) will be generated. In order to reduce costs, the scraps are usually crushed. The specific operation is as follows: first, the scraps of the corrugated box are placed in the crushing mechanism, and the blade or hammer in the crushing mechanism is driven to rotate by the rotating rod, so as to crush the scraps into small pieces. During the crushing process, the fragments will be continuously screened, and the large pieces will continue to remain in the crushing box for further crushing, while the small pieces will be discharged through the screen or small holes. Finally, the collection component will collect these small pieces of fragments;

[0004] However, in the process of die-cutting, the size of the scraps is usually affected by the die-cutting process. For example, the size design of the produced corrugated boxes and cardboards is unreasonable (that is, there are longer scraps in the die-cutting process), and the paper fibers between the cross-cutting gears of the die-cutting machine or the damage of the gears and bearing components may affect the accuracy of the cross-cutting, resulting in longer scraps. In the process of crushing the scraps, it is inevitable that longer cardboard will enter the crusher. Longer cardboards usually have greater strength and toughness, which makes them more difficult to be completely crushed during the crushing process. On the one hand, the crushing efficiency is reduced, and on the other hand, the workload of the crusher is increased. For this reason, we propose a scrap crushing device for corrugated box production. Summary of the invention

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figure 1-14The present invention provides a technical solution: a scrap crushing device for corrugated paperboard production. The present invention makes corresponding improvements to the technical problems in the background technology, including a crusher 1, a conveying mechanism 3 connected to the inside of the crusher 1 and used to convey corrugated paperboard 2, a baffle 31 is fixedly installed on the conveying mechanism 3, and the baffle 31 is used to prevent the corrugated paperboard 2 from being conveyed in a stacked state. It should be noted that the distance between the lowest point of the baffle 31 and the conveying mechanism 3 is greater than the thickness of one corrugated paperboard 2 and less than the superimposed thickness of two corrugated paperboards 2. Figure 3 As shown, the conveying mechanism 3 conveys the corrugated cardboard 2. If the corrugated cardboard 2 is not in an overlapping state (i.e., one corrugated cardboard 2), it will not be blocked by the baffle 31. When the corrugated cardboard 2 is in an overlapping state, it will be blocked by the baffle 31. In order to prevent the corrugated cardboard 2 with a longer size from entering the crusher 1, the present invention is designed as follows: fixed brackets 4 are fixedly installed on both sides of the conveying mechanism 3, and fixed shafts 41 are fixedly connected between the fixed brackets 4, and a plurality of detection shafts 42 rotatably connected to the outer wall thereof are installed on the fixed shaft 41, wherein a rolling ball 43 movably connected to the inner wall thereof is installed at the end of the detection shaft 42, and the end of the detection shaft 42 is located on the motion track of the corrugated cardboard 2, and an action rod frame 44 is fixedly installed on the outer wall of each detection shaft 42, and a mounting frame 45 fixedly connected to the fixed shaft 41 is provided on one side of the action rod frame 44, and a sensing element 46 for timing is fixedly installed on each mounting frame 45, and the sensing element 46 is located on the motion track of the action rod frame 44;

[0038] Combined with Figure 3 and attached Figure 4 As shown, in the initial state, the end of the detection shaft 42 is located on the movement trajectory of the corrugated cardboard 2, and then the corrugated cardboard 2 will act on the detection shaft 42 during the movement of the conveying mechanism 3. The detection shaft 42 will rotate on the fixed shaft 41 under the force, and during the rotation process, the action rod 44 on the outer wall of the detection shaft 42 will act on the sensing element 46 on the mounting frame 45 (in the initial state, the sensing element 46 will not be affected by the action rod 44). When the sensing element 46 is triggered, the timing starts. Since the conveying speed of the conveying mechanism 3 is constant, the length of the corrugated cardboard 2 can be effectively known. If the time when the sensing element 46 is triggered exceeds the set value (that is, it means that the length of the corrugated cardboard 2 exceeds the maximum processing length of the shredder 1), the corrugated cardboard 2 needs to be effectively processed. The following design is made for this purpose in the present invention:

[0039] A cutting knife group 5 for cutting the corrugated cardboard 2 is arranged on one side of the detection shaft 42, wherein connecting brackets 6 are fixedly installed on both sides of the conveying mechanism 3, and a driving part 7 is arranged between the connecting brackets 6, and the driving part 7 is used to control the cutting knife group 5 to cut the corrugated cardboard 2 whose detection data exceeds the standard. When the time when the sensing element 46 is triggered exceeds the set value, the driving part 7 will control the cutting knife group 5 to cut the corrugated cardboard 2 on the conveying mechanism 3. In the above, in the actual processing process, the corrugated cardboards 2 may be conveyed close to each other, and then the detection shaft 42 may be in a tilted state, that is, the sensing element 46 is always in a timing state. Correspondingly, the cutting knife will still cut the corrugated cardboard 2 under the action of the driving part 7, and will not affect the crushing work of the crusher 1;

[0040] As a further limitation in the present invention, the driving part 7 includes a connecting rod frame 71 arranged between the connecting brackets 6, and a limiting frame 72 is fixedly installed on the top of each connecting bracket 6, wherein magnetic sliders 73 are fixedly installed at both ends of the connecting rod frame 71, and the magnetic slider 73 is located inside the limiting frame 72 and is slidably connected to its inner wall, wherein an electromagnetic component 721 is fixedly installed on the inner wall of one end of the limiting frame 72, and the electromagnetic component 721 is located on one side of the magnetic slider 73, and the electromagnetic component 721 generates a magnetic force on the magnetic slider 73 when it is energized. It should be noted that the magnetic pole of the electromagnetic component 721 can be adjusted by changing the direction of the current. When the power is normally turned on, the electromagnetic component 721 generates a repulsive force on the magnetic slider 73 (that is, the magnetic poles of the electromagnetic component 721 and the magnetic slider 73 are the same), and when the current direction is changed, the electromagnetic component 721 generates an attractive force on the magnetic slider 73 (that is, the magnetic poles of the electromagnetic component 721 and the magnetic slider 73 are opposite);

[0041] A fixed frame 74 is provided below the connecting rod frame 71, and a plurality of guide shafts 75 slidably connected to the connecting rod frame 71 are fixedly installed on the top of the fixed frame 74. A plurality of return springs 76 sleeved on the guide shafts 75 are connected between the connecting rod frame 71 and the fixed frame 74. A reciprocating screw rod 77 rotatably connected to the inner wall at both ends of the fixed frame 74 is installed inside the fixed frame 74, and a driving slide block 78 slidably connected to the inner wall of the fixed frame 74 is installed on the reciprocating screw rod 77. The cutting knife group 5 is fixedly installed on the driving slide block 78, and when the reciprocating screw rod 77 rotates, the cutting knife group 5 is fixedly installed on the driving slide block 78. When the fixed frame 74 is moved, the driving slider 78 thereon will perform a limited movement in the fixed frame 74. During the movement, the cutting knife group 5 on the driving slider 78 will move synchronously with it. It should be noted that in the initial state, the cutting knife group 5 is located directly above the corrugated cardboard 2 and does not contact the corrugated cardboard 2. A plurality of support rod frames 742 are fixedly installed on the outer walls of both sides of the fixed frame 74, and a pressure plate 743 is arranged under each support rod frame 742. A buffer spring 744 is connected between the pressure plate 743 and the support rod frame 742. One end of the reciprocating screw rod 77 penetrates the fixed The inner wall of the frame 74 extends to the outside thereof, and a meshing gear 79 is fixedly installed at one end of the reciprocating screw rod 77 located outside the fixed frame 74. A meshing gear row 61 is fixedly installed on the side wall of one of the connecting brackets 6, and the meshing gear row 61 is located on the movement trajectory of the meshing gear 79. Telescopic shafts 741 are fixedly installed at both ends of the connecting rod frame 71. A limiting groove 62 is provided on the side wall of each connecting bracket 6. The end of the telescopic shaft 741 can slide in a limited position in the limiting groove 62. Two guide panels 63 are fixedly installed in the limiting groove 62. The limiting groove 62 includes The sliding area 621, the inclined downward area 622 connected to the sliding area 621, the cutting area 623 connected to the inclined downward area 622, and the inclined upward area 624 connected to the cutting area 623 and the sliding area 621, one of the guide panels 63 is fixedly installed at the intersection of the sliding area 621 and the inclined downward area 622, and the other guide panel 63 is fixedly installed at the intersection of the inclined upward area 624 and the sliding area 621, one side of the two guide panels 63 is an inclined surface, and the other side is a right angle surface, combined with the attached Fig.13 As shown, the guide panel 63 located at the intersection of the sliding area 621 and the inclined downward area 622: the side located in the sliding area 621 is an inclined surface, and the side where the sliding area 621 and the inclined downward area 622 intersect is a right-angled surface; the guide panel 63 located at the intersection of the inclined upward area 624 and the sliding area 621: the side located in the inclined upward area 624 is an inclined surface, and the side located in the sliding area 621 is a right-angled surface;

[0042] Combined with Fig.10 and attached Fig.14As shown, when the time when the induction element 46 is triggered exceeds the set value, the electromagnetic component 721 will be controlled to be energized in the form of an electrical signal. At this time, the electromagnetic component 721 will generate a repulsive force on the magnetic slider 73, and then the magnetic slider 73 will slide within the limit frame 72, and then drive the slider 78 to drive the connecting rod frame 71 to move in a directional manner. During the movement of the connecting rod frame 71, it will drive the fixed frame 74 to move in a directional manner under the action of the guide shaft body 75. Fig.12 and attached Fig.13As shown, during the movement of the fixed frame 74, the telescopic shaft 741 thereon starts to move from the initial end of the sliding area 621. In the initial state, the pressing plate 743 and the cutting knife group 5 are both located above the corrugated cardboard 2. It should be noted that the movement speed of the magnetic slider 73 in the limiting frame 72 must be the same as the speed at which the conveying mechanism 3 conveys the corrugated cardboard 2. The telescopic shaft 741 moves to the intersection of the sliding area 621 and the inclined downward area 622. At this time, it will contact one side of the right-angled surface of the guide panel 63, and enter the inclined downward area 622 under the action of the right-angled surface of the guide panel 63, and move along the trajectory of the inclined downward area 622, that is, move to the cutting area 623. At this time, the fixed frame The frame 74 will move forward and downward under the action of the guide shaft 75, and the return spring 76 will be in a stretched state. During the descending process of the fixed frame 74, the cutting knife group 5 connected to the driving slider 78 will descend to the side wall of the connecting bracket 6 (i.e., the side of the conveying mechanism 3), and the multiple support rod frames 742 on the fixed frame 74 will drive the pressing plate 743 to contact the surface of the corrugated cardboard 2 through the buffer spring 744. Since the conveying speed of the fixed frame 74 and the corrugated cardboard 2 is the same, the pressing plate 743 will limit the corrugated cardboard 2 to prevent the corrugated cardboard 2 from shaking due to the force during the subsequent cutting process. When the telescopic shaft 741 slides in the cutting area 623, the meshing gear The wheel 79 will contact the meshing tooth row 61 and rotate due to the meshing of the meshing tooth row 61 during the movement of the fixed frame 74, and then the reciprocating screw rod 77 will rotate. During the rotation of the reciprocating screw rod 77, the driving slider 78 thereon will drive the cutting knife group 5 to cut the corrugated cardboard 2. When the meshing gear 79 is separated from the meshing tooth row 61, the cutting knife group 5 will move one cycle on the reciprocating screw rod 77 with the driving slider 78, that is, the purpose of cutting the corrugated cardboard 2 is achieved. In the cutting process, the pressing plate 743 is always in contact with the corrugated cardboard 2 to achieve the purpose of limiting the corrugated cardboard 2. When the telescopic shaft 741 moves to the inclined upward area 624, the fixed frame 74 will Under the action of the telescopic shaft 741, the mechanical parts inside it are driven to move upward, and then the cutting knife group 5 returns to the top of the corrugated cardboard 2, and the pressing plate 743 does not act on the corrugated cardboard 2. The magnetic slider 73 continues to move, and the telescopic shaft 741 passes through the inclined surface of the guide panel 63 and enters the sliding area 621. Then the electromagnetic component 721 changes the direction of the current to generate an attractive force on the magnetic slider 73. The magnetic slider 73 drives the above-mentioned related parts to move in the direction of the initial position, and the telescopic shaft 741 moves from the other end of the sliding area 621 to the initial end. Therefore, through this design, the longer corrugated cardboard 2 can be effectively cut to facilitate the crushing of the crusher 1.

[0043] However, in actual use, it is inevitable that some of the corrugated cardboard 2 will be damp during transportation or storage. When the wet corrugated cardboard 2 enters the pulverizer 1, it is easy to adhere to the blade during the pulverization process, which will not only lead to incomplete pulverization, but also easily aggravate the wear of the cutter of the pulverizer 1. In view of this, the present invention makes the following design: a heating mechanism 10 is installed on the conveying mechanism 3, and the heating mechanism 10 is close to the feed end of the pulverizer 1. In order to save resources and avoid the heating mechanism 10 being in a heating state all the time, the present invention makes the following design: a support shaft is symmetrically installed on the fixed bracket 4 8, one of the support shaft bodies 8 is located above the conveying mechanism 3, and the other support shaft body 8 is located below the conveying mechanism 3, and a plurality of annular sleeves 81 are fixedly installed on each support shaft body 8, and a magnetic panel 82 is installed in the annular sleeve 81 and is slidably connected to the inner wall thereof, and an extension shaft body 83 is also fixedly installed on the magnetic panel 82 and is slidably connected to the inner wall of the annular sleeve 81, and the end of the extension shaft body 83 passes through the inner wall of the annular sleeve 81 and extends to the outside thereof, and an electromagnet body 84 is fixedly installed on the inner wall of the top of the annular sleeve 81, and the electromagnet body 84 generates a repulsive force on the magnetic panel 82 when it is energized, and the magnetic panel 82 A constant force spring 85 is connected to the inner wall of the bottom of the annular sleeve 81. One end of the extension shaft 83 located outside the annular sleeve 81 is also provided with a detection part 9 for detecting the wetness of the corrugated cardboard 2. As a further limitation in the present invention, the detection part 9 includes a detection frame 91 fixedly connected to the end of the extension shaft 83, and slots 92 are provided on both sides of the detection frame 91, and a sliding sleeve 93 slidably connected to the inner wall thereof is installed inside the slot 92. A detection rod frame 94 is provided inside the detection frame 91, and a transmission shaft 95 is fixedly installed on the detection rod frame 94. The transmission shaft 95 is rotatably connected to the inner wall of the sliding sleeve 93. A torsion spring 96 is connected between the end of the transmission shaft 95 and the sliding sleeve 93, wherein a block magnet 97 is also fixedly mounted on the outer wall of the transmission shaft 95, and force magnetic plates 98 are fixedly mounted on the outer walls of both sides of the detection frame 91, and the force magnetic plates 98 are located on the movement trajectory of the block magnet 97, and the magnetic poles of the force magnetic plates 98 and the block magnet 97 are opposite, and a spring body 99 connected to the outer wall of the sliding sleeve 93 is installed in the slot 92, wherein a button (not shown in the figure) is also installed in the slot 92, and the button is electrically connected to the heating mechanism 10. Since the button is a prior art component, the present invention does not describe it in detail;

[0044] Combined with Figure 3 and attached Figure 4In the initial state, the detection rod frame 94 is above the corrugated board 2 (the other detection rod frame 94 will be below the corrugated board 2), that is, it does not contact the corrugated board 2. When the sensing element 46 is triggered and the timing starts, the electromagnet body 84 is energized to generate a repulsive force on the magnetic panel 82. The magnetic panel 82 drives the detection frame 91 to move in a directional manner through the extended shaft 83. At this time, the constant force spring 85 is in a compressed state, and the slots 92 on both sides of the detection frame 91 will pass through the spring body. 99 applies a force to the sliding sleeve 93, and the sliding sleeve 93 makes the detection rod frame 94 contact with the corrugated cardboard 2 under the action of the transmission shaft body 95. Since the end of the corrugated cardboard 2 is sharp, when there is a wet area on the corrugated cardboard 2, the detection rod frame 94 will contact the wet area of ​​the corrugated cardboard 2 under the action of the electromagnet body 84 and enter the corrugated cardboard 2. It should be noted that the strength of the wet area of ​​the corrugated cardboard 2 will decrease, and it is easy to be damaged when subjected to force. Figure 7-9As shown, when the detection rod frame 94 enters the corrugated cardboard 2, the moving corrugated cardboard 2 will apply a force to the detection rod frame 94, and then the detection rod frame 94 will drive the transmission shaft 95 to rotate, and then the transmission shaft 95 moves in the sliding sleeve 93, and the torsion spring 96 is deformed. It should be noted that the elastic coefficient of the torsion spring 96 in the present invention is relatively small, so that the detection rod frame 94 can adjust the angle. When the transmission shaft 95 rotates, the block magnet 97 thereon will rotate to the force-applying magnetic plate 9 8, since the magnetic poles of the force-applying magnetic plate 98 and the block magnet 97 are opposite, the force-applying magnetic plate 98 will generate an attraction force on the block magnet 97, and the transmission shaft 95 is rotatably connected with the sliding sleeve 93, and the transmission shaft 95 will drive the sliding sleeve 93 to move in the slot 92, and the detection rod frame 94 moves synchronously with the transmission shaft 95, and the detection rod frame 94 leaves the corrugated cardboard 2, and the sliding sleeve 93 will compress the spring body 99 during the movement in the slot 92, and at the same time A trigger button (not shown in the figure) controls the heating mechanism 10 to start (the start time of the heating mechanism 10 can be specifically designed) to heat the wet area of ​​the corrugated cardboard 2 to avoid incomplete crushing of the corrugated cardboard 2. When the detection rod frame 94 leaves the inside of the corrugated cardboard 2, the transmission shaft 95 will be restored to the initial position under the action of the torsion spring 96, that is, the detection rod frame 94 returns to the initial state, and the block magnet 97 is not at the corresponding position of the force-applying magnetic plate 98. Under the action of the spring body 99, the sliding sleeve 93 is restored to the initial position. When the sensing element 46 is triggered again (that is, it is not timing), the electromagnet body 84 is powered off, and the magnetic panel 82 is restored to the initial position under the action of the constant force spring 85. When the sensing element 46 is triggered again and timing is performed, the electromagnet body 84 is powered on to repeat the above operation. Therefore, the structural design of the present invention can effectively process the corrugated cardboard 2 to prevent the longer or wet corrugated cardboard 2 from entering the pulverizer 1, so as to improve the crushing efficiency and quality.
