Description

Technical Field

[0001] The invention relates to the technical field of paper edge crushing, in particular to a paper edge crushing device for single-blade double-rotation synchronous slitting. Background Art

[0002] High-precision single-blade dual-rotation fully synchronous slitting equipment is mainly used for precision slitting of paper. It can slit the rewound paper roll into paper with specifications within the width, cutting length deviation less than 0.15mm and squareness less than 0.3mm according to the needs of the downstream packaging or printing market.

[0003] It is conceivable that when using high-precision single-blade double-rotation fully synchronous slitting equipment to slit paper, that is, cutting it into paper of corresponding width, there will inevitably be excess parts at the cutting point, that is, the paper edge.

[0004] In order to reduce resource consumption, paper edges are usually recycled and used. Specifically, the paper edges are shredded and broken into fibers, and appropriate amounts of water and chemicals (such as sodium hydroxide, etc., are added to soften the fibers during cooking) and cooked in a cooking device to further disperse and soften the fibers. After a series of processes such as washing, screening, and bleaching, the resulting pure pulp can be used to produce new paper products, realizing the recycling of paper resources.

[0005] When using cutting equipment (such as high-precision single-blade dual-rotation fully synchronous slitting equipment) to cut loose rolls of paper, the paper edges produced are mostly long strips. Unless torn by external force, the length of the long strip of paper is equal to the length of the roll of paper.

[0006] When recycling long strips of paper edges, they are first piled up at the cutting equipment, then collected by staff and sent to the shredding equipment, and finally shredded by the shredding equipment before they can be truly recycled.

[0007] From the above operation steps, it can be seen that the existing cutting equipment does not have the corresponding paper edge shredding process, and it is necessary to equip the corresponding shredding equipment separately, and arrange staff to operate the shredding equipment to shred the collected paper strips. This operation is not only not conducive to the timely recycling of waste paper strips, but also increases the labor cost of shredding waste paper strips. In addition, because the long paper strips are piled up at the cutting equipment, it is very likely that the paper edges will be piled up due to untimely cleaning, affecting the normal paper cutting work.

DETAILED DESCRIPTION

[0046] 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.

[0047] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0048] Example 1

[0049] like Fig.18 , Fig.19 As shown, in order to timely crush the paper edges formed by cutting, avoid the need to equip crushing equipment, and have the staff perform centralized crushing of the paper edges, this embodiment provides a new crushing device. The crushing device is installed at the cutting area of ​​the cutting equipment (such as a single-blade double-rotation synchronous slitting device), and the paper edges formed by cutting are moved to the crushing device, and the crushing device performs the initial and secondary crushing on them, thereby achieving timely crushing of the paper edges.

[0050] like Fig.18 As shown, before introducing the shredding device, a brief introduction is first given to the existing single-blade double-rotation synchronous slitting equipment. Specifically, it includes a tool and tool shaft system, a material conveying system, a double-rotation motion mechanism, a slitting adjustment and positioning system, and a control system.

[0051] The tool and cutter shaft system includes the tool and the cutter shaft. The tool is made of high-hardness, high-wear-resistant alloy steel and other materials. Its diameter is determined by factors such as the thickness, hardness and cutting width of the slitting material, and generally ranges from tens of millimeters to hundreds of millimeters. The material conveying system includes conveyor rollers and drive devices. The surface material and roughness of the conveyor roller are selected according to the material characteristics. Common driving methods include motor combined with belt drive, chain drive or gear drive, etc. Through these transmission methods, power is transmitted to the conveyor roller to achieve synchronization of material and tool slitting action. Some advanced equipment also uses variable frequency speed regulation technology to flexibly adjust the material conveying speed according to slitting requirements.

[0052] like Figure 1-16As shown, in order to realize the crushing of paper edges by the crushing device, the crushing device of the present invention includes a first conveyor 1, a second conveyor 3, a primary crushing component 2, a secondary crushing component 4, etc. The first conveyor 1 is arranged at the cutting area of ​​the single-blade double-rotation synchronous slitting device, and is arranged perpendicular to the traveling direction of the paper, and one end protrudes from the single-blade double-rotation synchronous slitting device. Therefore, under the action of the first conveyor 1, the paper falling on the first conveyor 1 can be controlled to be output from the cutting area of ​​the single-blade double-rotation synchronous slitting device, which provides convenience for the timely recycling of paper. The primary crushing component 2 is provided with two parallel groups, and both are arranged above the first conveyor 1 and below the paper. In addition, the primary crushing component 2 is arranged in parallel at the edge of the paper. Therefore, when the paper edge formed by cutting can fall into the primary crushing component 2 under the action of gravity, and the paper edge is cut into multiple sections under the operation of the primary crushing component 2. The paper cut into multiple sections falls on the first conveyor 1, and can be transferred to the outside of the single-blade double-rotation synchronous slitting device under the action of the first conveyor 1. The second conveyor 3 is obliquely arranged at the end of the first conveyor 1, and the lower end is located below the first conveyor 1, so that the paper detached from the first conveyor 1 directly falls on the second conveyor 3, and rises to a high place under the action of the second conveyor 3. The re-shredding component 4 is arranged on the side of the second conveyor 3, and the top is located below the top of the second conveyor 3. The paper detached from the second conveyor 3 falls into the re-shredding component 4, and can be shredded by the re-shredding component 4, and the shredded paper is collected at the same time. Through the cooperation of the above components, the paper edges formed by cutting can be shredded in time, which changes the current situation of using independent shredding equipment to clean them centrally, and at the same time avoids the accumulation of paper edges affecting the normal paper cutting process.

[0053] The first conveyor 1 and the second conveyor 3 mentioned here both include a conveyor belt, a driving device, rollers, idlers, a frame, etc. The conveyor belt is arranged on the frame in cooperation with the rollers and idlers, and the rollers are connected to the driving device through a transmission device. Therefore, when the driving device is working, the conveyor belt can be controlled to rotate to realize the transportation of objects.

[0054] The above-mentioned driving device mainly includes a motor, a reducer, a coupling, etc. The motor of the first conveyor 1 is set as a first motor 11, which is located outside the cutting area and controls the rotation of the conveyor belt. A bracket 12 is set on the side of the frame of the first conveyor 1. The bracket 12 is distributed on the outside of the conveyor belt frame and is connected to the frame of the cutting area. Therefore, under the action of the bracket 12, the first conveyor 1 is stably set on the single-blade double-rotation synchronous slitting device. The motor of the second conveyor 3 is set as a third motor 31, and the third motor 31 controls the rotation of the conveyor belt of the second conveyor 3. At the same time, a plurality of baffles 32 are set on the conveyor belt of the second conveyor 3. The plurality of baffles 32 are installed on the conveyor belt at intervals, and each baffle 32 is set along the width direction of the conveyor belt. The baffle 32 can prevent the paper from rising along the inclined direction of the second conveyor 3, and then the paper can be lifted to a high place.

[0055] In order to realize the preliminary cutting of the paper edges formed by cutting into multiple sections through the operation of the primary crushing component 2, the primary crushing component 2 comprises a silo 21, the width of the upper end of the silo 21 is greater than the width of the lower end, and a perforation 212 and a slot 211 are arranged on the side wall, the lengths of the perforation 212 and the slot 211 are equal, a slitting knife 213 is arranged through the perforation 212, and the blade of the slitting knife 213 can be inserted into the slot 211, so that the slitting knife 213 can reciprocate under the action of external force, and the paper edges falling into the silo 21 can be cut during the reciprocating movement, so as to prevent the long paper edges from falling directly on the first conveyor 1 and affecting its conveyance.

[0056] In order to control the reciprocating movement of the slitting blade 213, a power mechanism 5 is arranged between the two groups of primary crushing components 2, and the power mechanism 5 includes a second motor 51, a connecting plate 53 and a driving plate 54. A rotating disk 52 is arranged on the power output shaft of the second motor 51, and a rod body is fixedly arranged on the upper side edge of the rotating disk 52. The driving plate 54 is arranged in a cross structure and is provided with a guide hole 542, and the rod body of the rotating disk 52 extends into the guide hole 542. Therefore, when the second motor 51 controls the rotating disk 52 to rotate, the rod body is controlled to make a circular motion, thereby controlling the movement of the driving plate 54. Two connecting plates 53 are adjustable and arranged on both sides of the driving plate 54, and the ends away from each other are respectively connected to the two slitting blades 213. Under the action of the two connecting plates 53, the driving plate 54 can only move along the length direction of the connecting plate 53, and the two slitting blades 213 are controlled to reciprocate at the same time under the action of the two connecting plates 53, thereby realizing the slitting process of the paper edge.

[0057] In order to achieve the adjustable connection between the connecting plate 53 and the driving plate 54, grooves 531 are provided on the side walls of the two connecting plates 53 near each other, and bolts are threadedly penetrated through the ends. The central angle of the groove 531 is greater than 180°, and it is arranged along the length direction of the connecting plate 53. A convex column 541 is fixedly provided on the side wall of the driving plate 54, and a plurality of threaded grooves are provided. The convex column 541 is arranged in the groove 531, which can limit the movement of the connecting plate 53 and the driving plate 54, that is, the connecting plate 53 and the driving plate 54 can only move in the length direction of the connecting plate 53, which provides convenience for adjusting the relative positions of the driving plate 54 and the connecting plate 53 according to requirements. The end of the bolt penetrating through the connecting plate 53 is threadedly inserted into a certain threaded groove to realize the firm connection between the connecting plate 53 and the driving plate 54, which provides support for controlling the movement of the cutting knife 213 through the operation of the second motor 51. Of course, since the movement directions of the connecting plate 53 and the driving plate 54 have been limited by the cooperation of the convex column 541 and the groove 531, therefore, the end of the bolt can directly press against the side wall of the driving plate 54 to make the connecting plate 53 and the driving plate 54 stably connected.

[0058] In order to stably install the material bin 21 on the first conveyor 1, the primary crushing assembly 2 further includes two groups of support mechanisms 22. The two groups of support mechanisms 22 are respectively arranged at both ends of the primary crushing assembly 2, and each group of support mechanisms 22 includes a T-shaped plate and a sleeve frame 223. A socket 221 is fixedly provided at the bottom of the T-shaped plate, and a snap groove 222 is provided at the top. Both ends of the snap groove 222 are open. The socket 221 is installed on the frame of the first conveyor 1. Therefore, the T-shaped plate is stably installed relative to the first conveyor 1. The sleeve frame 223 is arranged in a U-shaped structure, and a snap column 224 is fixedly provided on the inner side wall. The sleeve frame 223 is sleeved on the top of the T-shaped plate, and the snap column 224 is located in the snap groove 222 to realize the stable and adjustable connection between the sleeve frame 223 and the T-shaped plate. In addition, a bolt is threadedly penetrated through the sleeve frame 223, and the end of the bolt presses against the T-shaped plate. Therefore, the sleeve frame 223 is stably arranged relative to the T-shaped plate, and it provides convenience for adjusting the position of the sleeve frame 223 according to requirements.

[0059] The end of the material bin 21 is connected to the sleeve frame 223. By changing the position of the sleeve frame 223, the adjustment of the position of the material bin 21 is synchronously realized, which provides convenience for it to adapt to different working environments. In addition, the cross plate installed below the second motor 51 is connected to the sleeve frames 223 of the other two groups of support mechanisms 22, that is, the second motor 51 can also be adjustably arranged on the first conveyor 1.

[0060] In order to realize the shredding of paper, the re-shredding component 4 includes a top bin 43, an intermediate bin 42 and a storage bin 41. The lower part of the intermediate bin 42 is set as a cylindrical body and the upper part is set as a polygonal body, that is, the middle part of the intermediate bin 42 is relatively narrow, which provides convenience for the dispersion of paper. The top bin 43 is also set as a polygonal frame and is installed above the intermediate bin 42. A through hole is provided on the end wall of the top bin 43, and a card slot 432 is provided on the inner side. The card slot 432 is inclined and connected with the through hole. At the same time, a guide plate 431 is provided at the space formed by the card slot 432 and the through hole. The bottom of the guide plate 431 is spaced from the end wall of the top bin 43. The guide plate 431 is inclined, which can extend the time for the paper to move in the top bin 43 and prevent the paper from entering the intermediate bin 42 in a concentrated manner to affect the shredding of the paper. The number of guide plates 431 can be determined according to actual conditions. The storage bin 41 is set below the intermediate bin 42 and is used to store shredded paper.

[0061] In order to realize the shredding of paper, a shredding mechanism 6 is arranged at the bottom of the intermediate bin 42, and the shredding mechanism 6 can shred the paper passing through the narrow part of the intermediate bin 42. Specifically, the shredding mechanism 6 includes a fourth motor 61, a first shredding knife 62, a second shredding knife 65 and a transmission device 64. The second shredding knife 65 and the first shredding knife 62 are arranged at the upper and lower ends of the transmission device 64. Under the action of the transmission device 64, the second shredding knife 65 and the first shredding knife 62 can be controlled to rotate in opposite directions, and at the same time, the falling paper can be shredded twice. An annular support plate 63 is arranged on the outside of the transmission device 64, and the annular support plate 63 is connected to the intermediate bin 42 or the storage bin 41, so that the transmission device 64 is stably arranged, and provides support for the stable operation of the first shredding knife 62 and the second shredding knife 65. The fourth motor 61 is arranged above the second shredding knife 65, and controls the rotation of the second shredding knife 65, thereby controlling the rotation of the first shredding knife 62.

[0062] In order to reduce the impact of the rotation of the pulverizer on the falling of paper, the pulverizer chamber structure and pulverizer layout can be optimized in actual manufacturing. For example, a relatively closed pulverizer chamber is designed to reduce the free flow of air and reduce the impact of the airflow generated by the rotation of the pulverizer on the paper. A buffer area is set in the pulverizer chamber, such as some soft barriers or guide structures around the pulverizer. When the airflow hits these structures, the airflow speed can be slowed down and its impact on the paper can be weakened, thereby preventing the paper from flying. Install special airflow guide devices, such as guide plates and ventilation slots. The guide plate can guide the airflow generated by the pulverizer to a specific direction, so that it flows along a predetermined path to prevent the airflow from directly impacting paper fragments. The ventilation slot can help to timely discharge the excess airflow generated by pulverization in the pulverizer chamber, maintain the air pressure balance in the chamber, and prevent the paper from being driven by the airflow due to changes in air pressure. Adjust the spacing and arrangement of the pulverizers in the pulverizer chamber. Appropriately increase the spacing between the pulverizers to avoid the paper from being too concentrated in a small area during the pulverization process and reduce the possibility of the paper flying due to excessive local airflow. At the same time, reasonable arrangement methods, such as staggered arrangement, are adopted to make the paper more evenly distributed in the crushing chamber and be more evenly affected by the airflow, thereby reducing the risk of paper flying.

[0063] In order to ensure the stable installation of the fourth motor 61, a material distribution mechanism 7 is provided inside the intermediate bin 42. The material distribution mechanism 7 includes an outer ring plate 71, a material guide cone shell 72 and a support frame 73. The outer ring plate 71 is installed outside the material guide cone shell 72 and connected to the intermediate bin 42. At the same time, the material guide cone shell 72 extends into the intersection of the cylinder and the polygon of the intermediate bin 42. This arrangement can utilize the structural characteristics of the material guide cone shell 72 to disperse the paper falling into the narrow part of the intermediate bin 42, that is, falling outside the fourth motor 61, providing support for the crushing knife to crush it. The support frame 73 is arranged below the material guide cone shell 72 and is surrounded by an isolation net 74. The fourth motor 61 is located in the isolation net 74 and is connected to the material guide cone shell 72.

[0064] In order to realize the opposite rotation of the first crushing knife 62 and the second crushing knife 65 through the transmission device 64, the transmission device 64 includes a first end plate 641, a second end plate 642, a shell 643 and a gear set 644. The first end plate 641 and the second end plate 642 are respectively connected to the first crushing knife 62 and the second crushing knife 65, and are connected to the two ends of the gear set 644. The gear set 644 is arranged in the shell 643. Therefore, under the action of the gear set 644, the opposite rotation of the first end plate 641 and the second end plate 642 can be realized, thereby controlling the first crushing knife 62 and the second crushing knife 65 to rotate oppositely.

[0065] Example 2

[0066] like Fig.17As shown, on the basis of Example 1, in order to realize the storage of paper, the storage bin 41 includes a square bin 414, a cylinder 413, etc. The cylinder 413 is arranged above the square bin 414 and connected to the middle bin 42. A port 415 is arranged at the end of the square bin 414, and a blocking plate 416 is detachably arranged at the port 415. Therefore, the port 415 can be unobstructed by removing the blocking plate 416, which provides convenience for taking out the accumulated paper. Of course, the port 415 can also be blocked by the blocking plate 416 to provide space for temporary collection of paper. In order to reduce the space occupied by the paper in the square bin 414, a squeezing plate 412 is arranged on the inner side of the square bin 414, and an electric cylinder 411 is arranged at the end of the square bin 414.
