Description

Technical Field

[0001] This invention relates to the field of paper edge crushing technology, specifically to a paper edge crushing device for single-blade double-rotation synchronous cutting. Background Technology

[0002] The high-precision single-blade double-rotation fully synchronous slitting equipment is mainly used for precision paper slitting. It can slit rewound paper rolls into paper with a width within a certain range, a length deviation of less than 0.15mm, and a squareness of less than 0.3mm according to the needs of downstream packaging or printing markets.

[0003] It is conceivable that when using a high-precision single-blade double-rotation fully synchronous slitting machine to slit paper into the corresponding width, an excess portion, namely the paper edge, will inevitably be formed at the cutting point.

[0004] To reduce resource consumption, paper scraps are typically recycled and reused. Specifically, the paper scraps are broken down into fibers, and then water and chemical agents (such as sodium hydroxide, used to soften the fibers during cooking) are added. The pulp is then cooked in a cooking apparatus to further disperse and soften the fibers. After a series of processes including washing, screening, and bleaching, the resulting pure pulp can be used to produce new paper products, thus achieving the recycling of paper resources.

[0005] When cutting equipment (such as a high-precision single-blade double-rotation fully synchronous slitting machine) is used to cut loosely rolled paper, the resulting paper edges are mostly long strips. Unless torn by external force, the length of the long strips is equal to the length of the rolled paper.

[0006] When recycling long strips of paper scraps, the scraps are first piled up at the cutting equipment, then collected and moved to the shredding equipment by staff. Finally, the shredding equipment is used to shred the scraps before they can be recycled.

[0007] As can be seen from the above operating steps, the existing cutting equipment does not have the corresponding paper edge shredding function. It requires additional shredding equipment and dedicated staff to operate it to shred the collected paper strips. This not only hinders the timely recycling and processing of waste paper strips but also increases the labor costs associated with shredding. Furthermore, the accumulation of long paper edges at the cutting equipment can easily obstruct normal paper cutting operations if not cleaned promptly. Summary of the Invention

[0008] The purpose of this invention is to provide a paper edge crushing device for single-blade double-rotation synchronous slitting, which aims to improve the problem that the cutting equipment does not have a paper edge crushing device, which is not conducive to timely crushing of paper edges.

[0018] In one embodiment of the present invention, the second conveyor includes a third motor and multiple baffles. The third motor controls the rotation of the conveyor belt of the second conveyor. The multiple baffles are installed at intervals on the conveyor belt, and each baffle is arranged along the width direction of the conveyor belt. The re-crushing component is arranged on the side of the second conveyor, and the end of the second conveyor is located directly above the re-crushing component.

[0046] 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 a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

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

[0048] Example 1

[0049] like Figure 18 , Figure 19 As shown, in order to promptly shred the paper edges formed during cutting, avoiding the need for dedicated shredding equipment and requiring manual operation for centralized shredding, this embodiment provides a new shredding device. This shredding device is installed in the cutting area of ​​the cutting equipment (such as a single-blade double-rotary synchronous slitting machine). The shredded paper edges move to this shredding device, where they undergo initial and secondary shredding processes, achieving timely shredding of the paper edges.

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

[0051] The cutting tool and cutter shaft system includes the cutting tool and the cutter shaft. The cutting tool is made of high-hardness, high-wear-resistant alloy steel or other materials. Its diameter is determined based on factors such as the thickness, hardness, and slitting width of the material to be cut, generally ranging from tens to hundreds of millimeters. The material conveying system includes conveyor rollers and a drive unit. The surface material and roughness of the conveyor rollers are selected according to the material properties. Common drive methods include motor combined with belt drive, chain drive, or gear drive, which transmit power to the conveyor rollers to synchronize the material and the cutting action of the cutting tool. Some advanced equipment also uses variable frequency speed control technology to flexibly adjust the material conveying speed according to the slitting requirements.

[0052] like Figure 1-16As shown, in order to achieve paper edge crushing through the crushing device, the crushing device of the present invention includes a first conveyor 1, a second conveyor 3, a primary crushing component 2, and a secondary crushing component 4. The first conveyor 1 is located in the cutting area of ​​the single-blade double-rotation synchronous slitting device and is set perpendicular to the paper's travel direction, with one end protruding 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 exit the cutting area of ​​the single-blade double-rotation synchronous slitting device, facilitating timely paper recycling. The primary crushing component 2 has two parallel sets, both located above the first conveyor 1 and below the paper. In addition, the primary crushing component 2 is set parallel to the edge of the paper. Therefore, when the cut paper edge falls into the primary crushing component 2 under the action of gravity, the primary crushing component 2 cuts the paper edge into multiple segments. The paper segmented into multiple segments falls onto the first conveyor 1, and can then 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 inclined at the end of the first conveyor 1, with its lower end located below the first conveyor 1. Therefore, the paper detached from the first conveyor 1 falls directly onto the second conveyor 3 and rises to a higher position under the action of the second conveyor 3. The re-shredding assembly 4 is located on the side of the second conveyor 3, with its top located below the top of the second conveyor 3. The paper detached from the second conveyor 3 falls into the re-shredding assembly 4, where it is shredded and collected. Through the cooperation of the above components, the paper edges formed during cutting can be shredded in a timely manner, changing the current situation of centralized cleaning using independent shredding equipment, and avoiding the accumulation of paper edges that would affect normal paper cutting.

[0053] The first conveyor 1 and the second conveyor 3 mentioned here both include conveyor belts, drive units, rollers, idlers, frames, etc. The conveyor belt is set on the frame with the cooperation of rollers and idlers, and the rollers are connected to the drive unit through transmission devices. Therefore, when the drive unit is working, the rotation of the conveyor belt can be controlled to realize the conveying of objects.

[0054] The aforementioned driving device mainly includes a motor, a reducer, and a coupling. The motor of the first conveyor 1 is a first motor 11, located outside the cutting area, and controls the rotation of the conveyor belt. A support 12 is provided on the side of the frame of the first conveyor 1, distributed outside the conveyor belt frame and connected to the frame of the cutting area. Therefore, under the action of the support 12, the first conveyor 1 is stably positioned on the single-blade double-rotation synchronous slitting device. The motor of the second conveyor 3 is a third motor 31, which controls the rotation of the conveyor belt of the second conveyor 3. Simultaneously, multiple baffles 32 are provided on the conveyor belt of the second conveyor 3, spaced apart, with each baffle 32 positioned along the width of the conveyor belt. The baffles 32 prevent the paper from rising along the inclined direction of the second conveyor 3, thereby lifting the paper to a higher position.

[0055] To achieve the initial cutting of paper edges into multiple segments through the operation of the primary crushing component 2, the primary crushing component 2 includes a hopper 21. The upper width of the hopper 21 is greater than the lower width, and the side wall is provided with a through hole 212 and a slot 211. The through hole 212 and the slot 211 are of equal length. A slitting blade 213 is inserted through the through hole 212. The blade of the slitting blade 213 can be inserted into the slot 211. Therefore, the slitting blade 213 can reciprocate under the action of external force. During its reciprocating movement, the paper edges falling into the hopper 21 can be cut, avoiding the long paper edges from falling directly onto the first conveyor 1 and affecting its conveying.

[0056] To control the reciprocating movement of the slitting blade 213, a power mechanism 5 is provided between the two sets of primary crushing components 2. The power mechanism 5 includes a second motor 51, connecting plates 53, and a drive plate 54. A turntable 52 is provided on the power output shaft of the second motor 51, and a rod is fixedly provided on the upper side edge of the turntable 52. The drive plate 54 is designed with a cross structure and is provided with a guide hole 542. The rod of the turntable 52 extends into the guide hole 542. Therefore, when the second motor 51 controls the turntable 52 to rotate, it controls the rod to make a circular motion, thereby controlling the movement of the drive plate 54. Two connecting plates 53 are adjustablely arranged on both sides of the drive plate 54, and their ends that are far apart from each other are respectively connected to the two slitting blades 213. Under the action of the two connecting plates 53, the drive plate 54 can only move along the length direction of the connecting plates 53. At the same time, the two slitting blades 213 are controlled to reciprocate simultaneously by the action of the two connecting plates 53, thereby realizing the slitting of the paper edge.

[0057] To achieve an adjustable connection between the connecting plate 53 and the driving plate 54, grooves 531 are provided on the sidewalls of the two connecting plates 53 at their respective ends, with bolts threaded through the ends. The central angle of the grooves 531 is greater than 180° and they are arranged along the length of the connecting plates 53. A protruding post 541 with multiple threaded grooves is fixedly provided on the sidewall of the driving plate 54. The protruding post 541 is positioned within the grooves 531, thus restricting the movement of the connecting plate 53 and the driving plate 54. Specifically, the connecting plate 53 and the driving plate 54 can only move along the length of the connecting plate 53, facilitating adjustments to their relative positions as needed. The bolts penetrating the connecting plates 53 are threaded into a specific threaded groove, securing the connecting plates 53 and the driving plate 54 together and providing support for controlling the movement of the slitting blade 213 via the second motor 51. Of course, since the movement direction of the connecting plate 53 and the driving plate 54 is restricted by the cooperation of the protruding post 541 and the groove 531, the end of the bolt can directly press against the side wall of the driving plate 54 to stably connect the connecting plate 53 and the driving plate 54.

[0058] To ensure the stable installation of the hopper 21 on the first conveyor 1, the primary crushing component 2 also includes two sets of support mechanisms 22. These two sets of support mechanisms 22 are respectively located at both ends of the primary crushing component 2, and each set of support mechanisms 22 includes a T-shaped plate and a sleeve frame 223. A socket 221 is fixedly installed at the bottom of the T-shaped plate, and a snap-fit ​​groove 222 is provided at the top. Both ends of the snap-fit ​​groove 222 are open. The socket 221 is installed on the frame of the first conveyor 1, thus ensuring the stable installation of the T-shaped plate relative to the first conveyor 1. The sleeve frame 223 is designed as a U-shaped structure, and snap-fit ​​posts 224 are fixedly installed on its inner sidewall. The sleeve frame 223 is fitted onto the top of the T-shaped plate, and the snap-fit ​​posts 224 are located in the snap-fit ​​groove 222, achieving a stable and adjustable connection between the sleeve frame 223 and the T-shaped plate. In addition, a bolt is threaded through the sleeve 223, and the end of the bolt presses against the T-shaped plate. Therefore, the sleeve 223 is stably set relative to the T-shaped plate, and provides convenience for adjusting the position of the sleeve 223 as needed.

[0059] The end of the hopper 21 is connected to the sleeve frame 223. When the position of the sleeve frame 223 is changed, the position of the hopper 21 is adjusted simultaneously, making it convenient to adapt to different working environments. In addition, the horizontal plate installed below the second motor 51 is connected to the sleeve frames 223 of the other two sets of support mechanisms 22, that is, the second motor 51 can also be adjusted and set on the first conveyor 1.

[0060] To enable paper shredding, the re-shredding assembly 4 includes a top chamber 43, an intermediate chamber 42, and a storage chamber 41. The lower part of the intermediate chamber 42 is cylindrical, while the upper part is polygonal, meaning the middle section of the intermediate chamber 42 is relatively narrow, facilitating paper dispersion. The top chamber 43 is also a polygonal frame and is installed above the intermediate chamber 42. It has a through-hole on its end wall and a slot 432 on its inner side. The slot 432 is angled and communicates with the through-hole. A guide plate 431 is positioned in the space formed by the slot 432 and the through-hole. A gap is left between the bottom of the guide plate 431 and the end wall of the top chamber 43. The angled guide plate 431 prolongs the time the paper spends moving within the top chamber 43, preventing paper from concentrating in the intermediate chamber 42 and affecting the shredding process. The number of guide plates 431 can be determined based on actual needs. The storage chamber 41 is located below the intermediate chamber 42 and is used to store the shredded paper.

[0061] To achieve paper shredding, a shredding mechanism 6 is installed at the bottom of the intermediate chamber 42. This shredding mechanism 6 can shred paper passing through the narrow section of the intermediate chamber 42. Specifically, the shredding mechanism 6 includes a fourth motor 61, a first shredding blade 62, a second shredding blade 65, and a transmission device 64. The second shredding blade 65 and the first shredding blade 62 are vertically distributed at the upper and lower ends of the transmission device 64. Under the action of the transmission device 64, the second shredding blade 65 and the first shredding blade 62 can be controlled to rotate in opposite directions, thus performing two shredding processes on the falling paper. An annular support plate 63 is provided on the outside of the transmission device 64. The annular support plate 63 is connected to the intermediate chamber 42 or the storage chamber 41, thereby stabilizing the transmission device 64 and providing support for the stable operation of the first shredding blade 62 and the second shredding blade 65. The fourth motor 61 is located above the second shredding blade 65 and controls the rotation of the second shredding blade 65, which in turn controls the rotation of the first shredding blade 62.

[0062] To reduce the impact of the rotating shredder blades on the paper's fall, the structure of the shredder chamber and the layout of the shredder blades can be optimized in actual manufacturing. For example, a relatively enclosed shredder chamber can be designed to reduce free airflow and decrease the impact of airflow generated by the rotating shredder blades on the paper. Buffer zones can be set up within the shredder chamber, such as soft barriers or guide structures around the shredder blades. When airflow impacts these structures, it slows down the airflow speed, weakening its impact on the paper and preventing it from flying. Specialized airflow guiding devices, such as deflectors and ventilation slots, can be installed. Deflectors can guide the airflow generated by the shredder blades in a specific direction, allowing it to flow along a predetermined path and preventing the airflow from directly impacting paper fragments. Ventilation slots can help to promptly expel excess airflow generated during shredding, maintaining air pressure balance within the chamber and preventing paper from being carried away by airflow due to pressure changes. The spacing and arrangement of the shredder blades within the shredder chamber can also be adjusted. Appropriately increasing the spacing between the shredder blades prevents paper from being concentrated in a small area during shredding, reducing the possibility of paper flying due to excessively strong local airflow. At the same time, by adopting a reasonable arrangement method, such as staggered arrangement, the paper can be more evenly distributed in the crushing chamber and the airflow effect is more uniform, thereby reducing the risk of paper flying.

[0063] To ensure stable installation of the fourth motor 61, a material distribution mechanism 7 is provided inside the intermediate chamber 42. The material distribution mechanism 7 includes an outer ring plate 71, a guide cone shell 72, and a support frame 73. The outer ring plate 71 is installed on the outside of the guide cone shell 72 and connected to the intermediate chamber 42. Simultaneously, the guide cone shell 72 extends into the junction of the cylindrical body and the polygonal body of the intermediate chamber 42. This arrangement utilizes the structural characteristics of the guide cone shell 72 to disperse the paper falling into the narrow space of the intermediate chamber 42, ensuring it falls outside the fourth motor 61 and providing support for the shredder to shred it. The support frame 73 is located below the guide cone shell 72 and is surrounded by an isolation net 74. The fourth motor 61 is located within the isolation net 74 and connected to the guide cone shell 72.

[0064] In order to achieve the opposite rotation of the first crushing blade 62 and the second crushing blade 65 through the transmission device 64, the transmission device 64 includes a first end plate 641, a second end plate 642, a housing 643, and a gear set 644. The first end plate 641 and the second end plate 642 are respectively connected to the first crushing blade 62 and the second crushing blade 65, and are also connected to both ends of the gear set 644. The gear set 644 is disposed in the housing 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 achieved, thereby controlling the opposite rotation of the first crushing blade 62 and the second crushing blade 65.

[0065] Example 2

[0066] like Figure 17As shown, based on Embodiment 1, to achieve paper storage, the storage compartment 41 includes a square compartment 414, a cylindrical body 413, etc. The cylindrical body 413 is disposed above the square compartment 414 and connected to the intermediate compartment 42. A port 415 is provided at the end of the square compartment 414, and a blocking plate 416 is detachably provided at the port 415. Therefore, the port 415 can be unblocked by removing the blocking plate 416, providing 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 paper collection. In order to reduce the space occupied by the paper in the square compartment 414, a squeezing plate 412 is provided on the inner side of the square compartment 414, and an electric cylinder 411 is provided at the end of the square compartment 414. The telescopic end of the electric cylinder 411 passes through the square compartment 414 and is connected to the squeezing plate 412. Therefore, the operation of the electric cylinder 411 can control the movement of the squeezing plate 412, push the paper to the blocking plate 416, and realize the paper compression process.

[0067] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
