Description

Technical Field

[0001] This application relates to the field of cutter rollers, and more particularly to a single-axis cutter roller with a detachable cutter holder module. Background Technology

[0002] A single-axis blade roller is a mechanical component that uses a single rotating shaft to drive blades to perform cutting, shredding, and other functions. It is widely used in industries such as packaging, printing, plastics, and papermaking. The design of a detachable blade holder module further enhances its flexibility and maintenance efficiency.

[0003] A search revealed Chinese Patent Publication No. CN212418210U, which discloses an anti-winding single-axis cutter roller, comprising a roller shaft and multiple movable cutter seats. The movable cutter seats protrude from the outer surface of the roller shaft and are spaced apart along the axial direction. Movable cutters are mounted on the movable cutter seats, and the interval between two adjacent axially adjacent movable cutters forms a meshing space for matching with fixed cutters. The roller shaft has protruding structures corresponding to the meshing space, with the edges of the protruding structures being cutting edges protruding from the outer surface of the roller shaft. The radial distance between the cutting edges and the axis of the roller shaft is equal at all points. The cutting edges of the protruding structures cut the material wound in the meshing space, and the equal radial distance between the cutting edges and the axis of the roller shaft ensures effective shearing cooperation between the cutting edges and the fixed cutters, avoiding potential interference between the cutting edges and the fixed cutters, improving the cutting and crushing efficiency of the cutter roller, and ensuring the reliability of the cutter roller's unpacking process.

[0004] Although the aforementioned patent avoids potential interference between the cutting edge and the fixed blade, thus improving the cutting and crushing efficiency of the cutter roller, it is inconvenient to maintain, and the downtime during maintenance is too long, increasing costs. Therefore, a single-axis cutter roller with a detachable blade holder module is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this application is to provide a single-axis cutter roller with a detachable cutter holder module, which aims to address the problems of inconvenient maintenance and excessive downtime and increased costs during maintenance.

[0006] The single-axis cutter roller with a detachable cutter holder module provided in this application adopts the following technical solution: A single-axis cutter roller with a detachable cutter holder module includes a roller shaft, a connecting mechanism fixedly connected to the outside of the roller shaft, a plurality of scraper blades fixedly connected to the outside of the roller shaft, a fixing mechanism fixedly connected to the outside of the connecting mechanism, a limiting mechanism slidably connected to the inner wall of the connecting mechanism, and a replacement mechanism fixedly connected to the outside of the connecting mechanism. The fixing mechanism includes multiple connecting blocks. Two of the connecting blocks are fixedly connected to the outside of the connecting mechanism. Two limiting grooves are formed on the inner wall of the connecting mechanism. The outer side of the connecting blocks is slidably connected to the inner wall of the limiting grooves. A limiting component is slidably connected to the bottom of the connecting mechanism.

[0007] Through the above technical solution: the external connecting mechanism and the fixing mechanism of the roller shaft cooperate to achieve stable installation of the tool holder module; the scraper can clean impurities on the roller shaft surface, improving work efficiency; the connecting block of the fixing mechanism slides along the limiting groove, facilitating quick positioning and disassembly; the limiting component further strengthens the connection to prevent loosening; the limiting mechanism slides on the inner wall of the connecting mechanism, constraining the position of the tool holder and ensuring cutting accuracy; the replacement mechanism allows for quick blade replacement, reducing maintenance costs; the overall modular design makes the tool roller both stable and flexible, suitable for processing scenarios with frequent tool changes, extending equipment life and improving production efficiency.

[0008] Preferably, the limiting mechanism includes a limiting post, the limiting post being slidably connected to the inner wall of the connecting mechanism, a connecting ring 1 being fixedly connected to the outside of the limiting post, a spring 2 being fixedly connected to the outside of the connecting ring 1, a connecting ring 2 being fixedly connected to the other end of the spring 2, and a positioning post being fixedly connected to the outside of the limiting post.

[0009] By adopting the above technical solution, the limiting post of the limiting mechanism slides on the inner wall of the connecting mechanism, achieving precise guidance and displacement control. The connecting ring one cooperates with the spring two to provide elastic buffer for the limiting post, reducing motion impact and noise. The connecting ring two fixes the other end of the spring two to ensure stable transmission of elastic force. The positioning post and the limiting post are fixedly connected and can cooperate with the sliding groove of the connecting plate to further constrain the motion trajectory. This structure keeps the equipment stable during operation, prevents parts from loosening or misaligning, extends service life, and improves operational accuracy and reliability. It is suitable for mechanical systems that require precise control and buffer protection.

[0010] Preferably, the inner wall of the second connecting ring is slidably connected to the outside of the limiting post, and the inner wall of the second spring is slidably connected to the inner wall of the limiting post.

[0011] By adopting the above technical solution, the inner wall of the connecting ring 2 slides outside the limiting post to achieve precise guidance and limiting, ensuring the stability of the mechanism's movement trajectory. The inner wall of the spring 2 slides with the inner wall of the limiting post, and can be compressed and deformed axially when subjected to force, effectively buffering impact and vibration. This structure allows the limiting post to remain stable when subjected to lateral force, preventing displacement or jamming. At the same time, the elastic restoring force of the spring 2 ensures accurate component reset. The sliding connection reduces friction loss and extends service life. It is suitable for mechanical systems that frequently start and stop or require precise control, improving the reliability and stability of equipment operation.

[0012] Preferably, the connecting mechanism includes a connecting plate, the outer wall of which is fixedly connected to the outside of the connecting block, and a mating plate is movably connected to the outside of the connecting plate.

[0013] By adopting the above technical solution, the connecting plate and the connecting block of the connecting mechanism are fixedly connected, providing stable support for the overall structure. The movable connecting plate allows for flexible adjustment or replacement according to actual needs, enhancing the adaptability and maintainability of the equipment. When different components need to be connected or the working position needs to be adjusted, the connecting plate can quickly cooperate with the connecting plate to achieve a stable connection. This modular design simplifies the installation and disassembly process, reduces maintenance costs, and ensures the reliability of the connection, enabling the equipment to maintain efficient operation under various working conditions and extend its service life.

[0014] Preferably, the connecting plate has a groove on its outer side, the positioning post is slidably connected to the inner wall of the groove, and the other end of the limiting post is slidably connected to the outer side of the docking plate.

[0015] By adopting the above technical solution, a sliding groove is opened on the outside of the connecting plate, allowing the positioning column to slide along the inner wall of the groove, realizing flexible relative movement between the docking plate and the connecting plate. The other end of the limiting column slides outside the docking plate, which not only limits the displacement range but also guides the sliding direction, ensuring that the connecting mechanism maintains a stable trajectory during movement. This sliding connection structure can effectively absorb vibration and impact, reduce component wear, and facilitate installation and disassembly, improving equipment maintenance efficiency. It is suitable for mechanical systems that require frequent adjustment or replacement of components.

[0016] Preferably, the replacement mechanism includes multiple reinforcing blocks, the external of which are fixedly connected to the outside of the connecting mechanism, the inner wall of each reinforcing block is fixedly connected to a blade, and the external of each reinforcing block is fixedly connected to two fixing posts.

[0017] By adopting the above technical solution, multiple reinforcing blocks of the replacement mechanism are fixed to the outside of the connecting mechanism, which enhances the structural stability and ensures the reliability of the blade during operation. The blade on the inner wall of the reinforcing block can perform cutting tasks efficiently and is easy to disassemble and replace, improving maintenance efficiency. The design of the fixing column provides precise positioning and firm fixation, so that the blade remains stable under high-speed operation or heavy load conditions, reducing deviation and vibration, extending service life, while reducing replacement difficulty and cost, and ensuring continuous and efficient operation of the equipment.

[0018] Preferably, the limiting component includes a plurality of cylinders, the tops of the plurality of cylinders being slidably connected to the bottom of the connecting mechanism, a limiting ring being slidably connected to the outside of the cylinders, a spring being fixedly connected to the outside of the limiting ring, and a fixing ring being fixedly connected to the other end of the spring.

[0019] By adopting the above technical solution, the tops of multiple cylinders of the limiting component are slidably connected to the bottom of the connecting mechanism to achieve flexible support and guidance. The limiting ring can slide along the cylinder, and together with the spring and the fixed ring, they form an elastic buffer structure. When the connecting mechanism is subjected to force, the spring is compressed and deformed to absorb energy, effectively reducing impact and vibration and protecting the components from damage. At the same time, the limiting ring restricts the displacement range of the cylinder, ensuring smooth operation of the mechanism and improving the reliability and service life of the equipment.

[0020] Preferably, the roller shaft has multiple limiting holes on its outer side, the spring is fixedly connected to the inner wall of the limiting holes, and the limiting ring is fixedly connected to the inner wall of the limiting holes.

[0021] By adopting the above technical solution, multiple limiting holes are opened on the outside of the roller shaft, and the spring and the limiting ring are fixed to the inner wall of the limiting holes. This can effectively limit the axial and radial displacement of the roller shaft, enhance the stability of the roller shaft, provide elastic buffering, reduce vibration and noise during operation, and extend the service life of the roller shaft. The limiting ring further strengthens the structure, prevents the components from loosening, and ensures that the roller shaft can maintain accurate positioning under high-speed operation or heavy load conditions, thereby improving the overall performance and reliability of the equipment.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. In this utility model, the roller is installed in the machine, and the connecting block on the connecting plate is placed in the limiting groove. This operation can ensure the initial stability of the connection. The connecting block can automatically pop out the cylinder on the connecting plate through the action of spring 1 to complete the connection, ensuring a tight fit between the connecting plate and the mating plate. It also improves the convenience of disassembly, thereby greatly reducing the time spent by workers in the maintenance or adjustment process. 2. In this utility model, after the initial connection is completed, the connecting plate and the docking plate are further fixed. At this time, the sliding positioning post plays a key role. The sliding positioning post pushes the limiting post into the connecting ring one, and the limiting post at the other end further restricts the movement of the docking plate to prevent it from separating from other parts, thereby ensuring a stable connection between the connecting mechanism and the roller. Under this precise positioning and fixing design, the equipment can maintain efficient operation during work, while preventing the connecting parts from falling off due to vibration or external force, thus improving the safety and durability of the equipment.

[0024] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail below.

[0025] Example 1: A single-axis cutter roller with a detachable cutter holder module, see reference. Figures 1 to 3The system includes a roller 1, with a connecting mechanism 2 externally fixed to the roller 1. This connecting mechanism 2 enables quick assembly and disassembly of the tool holder module, significantly improving maintenance efficiency. Multiple scraper blades 3 are externally fixed to the roller 1, effectively removing residual material from the roller surface and keeping the working surface clean. A fixing mechanism 4 is externally fixed to the connecting mechanism 2, employing a double-locking design to ensure the stability of the tool holder module during high-speed operation. A limiting mechanism 5 is slidably connected to the inner wall of the connecting mechanism 2, providing continuous clamping force through spring preload to prevent loosening during operation. A replacement mechanism 6 is externally fixed to the connecting mechanism 2, featuring a modular design that allows for quick replacement of individual blades without affecting the overall structure. The fixing mechanism 4 includes multiple connecting blocks 41, with two connecting blocks 41 externally fixed to the outside of the connecting mechanism 2. The connecting blocks 41 employ a trapezoidal structure design to ensure secure installation. To ensure the guiding accuracy, the inner wall of the connecting mechanism 2 has two limiting grooves 42, which form a precise fit with the connecting block 41 to achieve radial positioning. The outer side of the connecting block 41 is slidably connected to the inner wall of the limiting groove 42. This sliding fit structure allows the tool holder module to move smoothly along the axial direction. The bottom of the connecting mechanism 2 is slidably connected to a limiting component 43, which automatically pops out by a spring to achieve axial positioning, simplifying the installation operation process. The replacement mechanism 6 includes multiple reinforcing blocks 61. The reinforcing blocks 61 adopt a split structure, which facilitates the individual replacement of worn parts. The outer side of the multiple reinforcing blocks 61 is fixedly connected to the outside of the connecting mechanism 2. The bolt connection method facilitates the adjustment of the installation position. The inner wall of the reinforcing block 61 is fixedly connected to a blade 62. The blade 62 adopts a quick-release design, which can be replaced by simply removing the fixing post 63. The outer side of the reinforcing block 61 is fixedly connected to two fixing posts 63. The fixing posts 63 adopt an anti-loosening thread structure to ensure working reliability. Specifically, roller 1 serves as the core support component, and its external connection mechanism 2 enables the rapid assembly and disassembly of the modular tool holder. The connection mechanism 2 adopts a precise fit design between the trapezoidal connecting block 41 and the limiting groove 42, which can automatically guide and position during installation, ensuring the radial installation accuracy of the tool holder module. The fixing mechanism 4 achieves reliable fixing through a double locking mechanism: on the one hand, the limiting component 43 automatically pops out under the action of the spring, completing the initial axial positioning; on the other hand, the limiting mechanism 5 provides continuous clamping force through the spring preload, effectively preventing loosening caused by vibration during high-speed operation. The replacement mechanism 6 adopts an innovative modular design. The reinforcing block 61 is fixed to the connecting mechanism 2 by bolts and can be replaced individually according to the wear condition. The blade 62 adopts a quick-release structure. Replacement can be completed by simply removing the fixing column 63 with anti-loosening thread design, which greatly simplifies the maintenance process. The scraper blade 3 is evenly arranged around the roller shaft 1 and continuously cleans the residual material on the working surface during operation, keeping the processing area clean.

[0026] Reference Figure 2 and Figure 4 The limiting mechanism 5 includes a limiting post 52, which adopts a stepped shaft design and has both guiding and limiting functions. The limiting post 52 is externally slidably connected to the inner wall of the connecting mechanism 2. A wear-resistant bushing is provided at the sliding connection to extend its service life. A connecting ring 53 is fixedly connected to the outside of the limiting post 52. The connecting ring 53 acts as a spring support to ensure uniform force distribution. A spring 54 is fixedly connected to the outside of the connecting ring 53. The spring 54 provides a stable preload to ensure a tight fit between the connecting plate 21 and the mating plate 22. A connecting ring 56 is fixedly connected to the other end of the spring 54. The connecting ring 56 has an anti-rotation structure to prevent spring torsion failure. The external fixed connection is a positioning post 55. The positioning post 55 cooperates with the slide groove 51 to precisely control the limit stroke. The inner wall of the connecting ring 56 is slidably connected to the outside of the limiting post 52. This sliding cooperation ensures that the spring force is always along the axial direction. The inner wall of the spring 54 is slidably connected to the inner wall of the limiting post 52. The built-in spring design saves space and is dustproof. The connecting mechanism 2 includes a connecting plate 21. The connecting plate 21 is made of high-strength alloy steel to ensure structural rigidity. The outer wall of the connecting plate 21 is fixedly connected to the outside of the connecting block 41. The welded connection ensures the overall strength. The outside of the connecting plate 21 is movably connected to a docking plate 22. The docking plate 22 is provided with a guide slope to facilitate installation and positioning. Specifically, the limiting mechanism 5 achieves a dual function through the step-shaft design of the limiting post 52: its upper guide section precisely matches the wear-resistant bushing on the inner wall of the connecting mechanism 2 to ensure axial movement accuracy; the lower limiting section precisely controls the locking stroke through the cooperation of the positioning post 55 and the T-shaped slide 51. During installation, the guide slope of the docking plate 22 guides the limiting post 52 into place, and the second spring 54 applies a constant preload through the first connecting ring 53 and the second anti-rotation design connecting ring 56, so that the connecting plate 21 and the docking plate 22 are tightly pressed together. The built-in spring structure avoids external contamination. The connecting plate 21 made of high-strength alloy steel and the welded connecting block 41 together ensure the overall rigidity and ensure the stability of the tool holder module during high-speed operation. This design achieves a balance between quick disassembly and reliable locking.

[0027] Reference Figure 1 and Figure 2The connecting plate 21 has a groove 51 on its outer side. The groove 51 adopts a T-slot design, which serves both guiding and anti-detachment functions. The positioning post 55 is slidably connected to the inner wall of the groove 51. This fit can precisely control the movement trajectory of the limiting post 52. The other end of the limiting post 52 is slidably connected to the outer side of the docking plate 22. A self-lubricating bearing is provided at the connection to ensure smooth operation. The limiting assembly 43 includes multiple cylinders 431. The ends of the cylinders 431 have spherical structures to facilitate automatic centering and positioning. The tops of the multiple cylinders 431 are slidably connected to the bottom of the connecting mechanism 2 to ensure positioning accuracy. A limiting ring 432 is slidably connected to the outer side of the cylinders 431. The limiting ring 432 is made of hard material. The roller shaft 1 is equipped with multiple limiting holes 435 on its exterior. The positions of the limiting holes 435 are precisely calculated to ensure accurate positioning of each tool holder module. The spring 433 is fixedly connected to the inner wall of the limiting hole 435 with an interference fit to ensure reliable connection. The limiting ring 432 is fixedly connected to the inner wall of the limiting hole 435 on its exterior. A sealing ring is provided at the fixing point to prevent foreign objects from entering and affecting the operation. Specifically, the sliding groove 51 of the connecting plate 21 adopts a T-slot structure, which precisely matches the positioning post 55 to ensure that the limiting post 52 moves along the predetermined trajectory and avoids deviation. When the limiting post 52 is inserted into the docking plate 22, the self-lubricating bearing at its end reduces friction and makes the locking action smoother. The cylinder 431 of the limiting component 43 automatically centers through the spherical end and is inserted into the limiting hole 435 under the elastic force of the spring 433 to achieve axial fixation. The limiting ring 432 is hardened and works with the sealing ring to prevent foreign objects from entering and ensure long-term stable operation. The positions of each limiting hole 435 are precisely arranged so that the tool holder module maintains a precise circumferential distribution after installation, ensuring machining accuracy.

[0028] The implementation principle of this embodiment is as follows: the tool holder module is quickly assembled and disassembled through the coordinated action of the connecting mechanism 2 and the fixing mechanism 4. During installation, the connecting block 41 on the connecting plate 21 is slid into the limiting groove 42, so that the connecting mechanism 2 and the roller 1 are initially positioned. At this time, the cylinder 431 in the limiting component 43 automatically pops out under the elastic force of the spring 433 and is locked into the limiting hole 435, so that the connecting plate 21 and the docking plate 22 are axially fixed to prevent loosening. This design greatly simplifies the installation process, and workers can complete the initial fixing without additional tightening operations, significantly improving assembly efficiency.

[0029] For further reinforcement, the positioning post 55 of the sliding limiting mechanism 5 drives the limiting post 52 to move along the slide groove 51, so that it inserts into the corresponding hole of the docking plate 22. At the same time, the second spring 54 continuously applies pressure to ensure that the limiting post 52 is always tightly attached to the docking plate 22, forming a stable locking structure. This double locking mechanism effectively prevents the tool holder module from falling off due to vibration during high-speed rotation, improving operational reliability.

[0030] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
