Its main function is to precisely cut large sheets of material (i.e., paper) into the required sizes or shapes to meet different usage requirements. The paper cutters in the prior art cannot ensure the precise feeding and positioning of the paper before cutting, and even cannot guarantee the flat feeding of the paper roll. Utility Model Content

[0003] An embodiment of the present application provides a paper cutting device, a paper separating device, and a paper cutter. A number of technical improvements and innovative designs are made mainly aiming at the deficiencies in terms of paper cutting efficiency, precision, safety, and equipment adaptability, so as to meet the market demand for high-quality and high-efficiency paper processing equipment.

[0004] In a first aspect of an embodiment of the present application, a paper separating device is provided, which includes a paper separating device housing having a hollow structure with an inner diameter larger than the diameter of the paper tube carrying the paper to be cut. There is a paper outlet on the side wall of the paper separating device housing, and the paper to be cut can be pulled out through the paper outlet for cutting. At least one parallel guide rail is provided on the side wall of the paper separating device housing, and the parallel guide rail is parallel to the axis of the paper separating device housing. At least one of the parallel guide rails is adjacent to the paper outlet, and the parallel guide rail can ensure flat paper feeding while preventing the paper tube from being pulled out through the paper outlet. The structure of the paper separating device housing and the provided parallel guide rails make the entire paper separating device system ensure stability and durability during long-term use while maintaining a compact structure, reduce the maintenance cost, and extend the service life of the equipment.

[0005] In the second aspect of the embodiments of the present application, a paper cutter is provided, which includes a cutter assembly, comprising a paper picking member and a cutter.

[0035] Embodiment 1

[0036] As Figure 1 , Figure 2 , Figure 6 shown, according to an embodiment of the present application, a cutter assembly 3 is provided, which includes a paper picker 31. The paper picker 31 includes a first part 31a and a second part 31b connected to the first part 31a. The outer shape of the first part 31a of the paper picker 31 is elongated, which can ensure accurate positioning of the paper 41 during the cutting process. The end of the first part 31a of the paper picker 31 is a flat and pointed paper picking end 311. The flat and pointed design of the paper picking end 311 can accurately insert under the paper 41, reducing damage to the surface of the paper 41. Especially for fragile or high-gloss paper 41, it can effectively protect the integrity of the paper 41, ensure that the edge of the cut paper 41 is smooth and burr-free, and improve the cutting quality.

[0037] The paper picking end 311 can extend under the paper 41 to be cut and lift it up from the placement plane; the paper picking member 31 is provided with a cutting knife 32, the cutting knife 32 is arranged on the second part 31b of the paper picking member 31, and the cutting edge 321 of the cutting knife 32 faces the paper picking end 311, avoiding multiple papers being cut simultaneously or cutting misalignment, thus improving the cutting accuracy and efficiency. The cutting edge 321 of the cutting knife 32 is opposite to the advancing direction of the paper 41 to be cut, ensuring that whether it is a straight-line cutting or a cutting at a specific angle, the straightness and accuracy of the cutting can be maintained, suitable for the cutting requirements of papers 41 of different sizes and types, and enhancing the versatility and adaptability of the cutting knife assembly.

[0038] The upper surface of the paper picking member 31 from the paper picking end 311 to the cutting edge 321 is a contact bearing surface 312, and the contact bearing surface 312 is an arched arc surface, which is used to contact and support the paper 41 upward; the contact bearing surface 312 of the paper picking member 31 is designed as an arched arc surface, and the arched arc surface can provide a large area and evenly distributed support point after the paper 41 is lifted, ensuring that the paper 41 is in a stable state before cutting, avoiding offset or jitter during the cutting process, and thus improving the cutting accuracy and the flatness of the paper 41. The arched arc-shaped contact bearing surface 312 has a better fit with the paper 41, and whether it is a thin paper or a thicker cardboard, it can be well supported, ensuring the consistency of the cutting process and the wide range of applications.

[0039] The cutting edge 321 of the cutting knife 32 is inclined relative to the contact bearing surface 312, which is beneficial for the paper 41 to naturally lean towards the cutting edge 321 during the paper feeding process, reducing the cutting resistance, making the cutting process smoother, and at the same time ensuring that the cutting line is neater and cleaner, improving the overall quality and efficiency of the cutting. The inclination direction of the cutting edge 321 forms a preferred angle of 45° - 135° with the plane where the feeding direction of the paper 41 to be cut is located. The preferred angle is designed within the range of 45° - 135°, which can significantly improve the efficiency of the cutting process and the quality of the cutting surface. Within this angle range, the cutting edge can cut into the paper with the least resistance, reduce the distortion and debris generation during cutting, make the cutting edge smoother and flatter, improve the aesthetics and usability of the finished product. By selecting an appropriate angle, the force and energy consumption required for cutting can be reduced, the operating cost of the equipment can be lowered. At the same time, an appropriate inclination angle can also optimize the force distribution of the cutting tool, reduce the friction and wear between the cutting edge and the paper, extend the service life of the cutting tool, and reduce the maintenance cost. Within this angle range, it helps to maintain a stable contact between the cutting edge and the paper during the cutting process, avoid the phenomenon of tool jumping or skewing, and ensure the straightness and accuracy of the cutting line. Especially in continuous high-speed cutting operations, this design can improve the stability and consistency of the entire production process.

[0040] Embodiment 2

[0041] Such asFigures 1 to 6 As shown, according to an embodiment of the present application, a paper cutter is provided, including a cutter assembly 3, which includes a lifting member 31 and a cutter 32. The first end of the lifting member 31 has a paper lifting end 311, which can extend under the paper 41 to be cut and lift it upward. The paper lifting end 311 can accurately separate the paper 41 from the stack and lift it upward, ensuring that only a single sheet of paper is cut each time, avoiding the error of cutting multiple sheets of paper at the same time, and improving the cutting accuracy. The lifting member 31 is provided with a cutter 32 near its second end, and the blade 321 of the cutter 32 corresponds to the travel direction of the paper 41 to be cut, ensuring the continuity and efficiency of the cutting process. The second end of the lifting member 31 has a spring buckle 313, and the paper cutter housing 16 is provided with a spring buckle mounting groove 19. The second end of the lifting member 31 is detachably connected to the spring buckle mounting groove 19 through the spring buckle 313.

[0042] The housing 1 includes a paper cutter housing 16, and the cutter assembly 3 is connected to the paper cutter housing 16. The left and right sides of the paper cutter housing 16 both have side portions 161 extending downward, and the lower edges 162 of the side portions 161 on the left and right sides can be pressed downward on both sides of the paper 41 to be cut that is picked up by the pick-up member 31, so that both sides of the picked-up paper 41 can be pressed firmly on the placement plane before cutting, effectively preventing the paper 41 from moving or curling during the cutting process, ensuring the stability of the cutting process, and thus improving the flatness of the cutting edge and the overall cutting quality. The second end of the pick-up member 31 is connected to the paper cutter housing 16, and the cut paper 41 is divided into two sheets of paper from the second end of the pick-up member 31, and the pressing effect of the side portion 161 reduces the risk of the operator directly contacting the cutter, thereby improving the safety of use. At the same time, the operation process is simpler, and the user only needs to place the paper 41, and the rest of the positioning and pressing actions are automatically completed by the device.

[0043] The pressure guide assembly 2 is connected to the paper cutter housing 16 and is disposed between the side portions 161 on the left and right sides. When the paper 41 to be cut enters the cutter assembly 3, the pressure guide assembly 2 assists in positioning and linearly slides and guides the paper 41 to be cut toward the blade 321. The pressure guide assembly 2 not only simplifies the introduction steps of the paper 41, but also automatically assists in positioning and linearly slides and guides the paper 41 when it enters the cutter assembly 3, greatly improving the fluency and automation level of the operation, reducing the tediousness of manual operation, and improving work efficiency.

[0044] The paper picking end 311 is exposed outward relative to the paper feeding end 164 of the paper cutter housing 16, which can optimize the paper introduction process. The paper picking end 311 is exposed outward, making it easier for the paper 41 to be introduced into the cutter assembly 3. The user does not need to laboriously stuff the paper 41 into a small space, thereby improving the convenience of use.

[0045] When the upper surface from the paper picking end 311 to the cutting blade 321 serves as the contact and bearing surface 312 for the paper 41 to be cut. The contact and bearing surface 312, being a smoothly transitioning surface, helps the paper 41 to smoothly transition from the paper picking end 311 to the cutting blade 321, reducing wrinkles or offsets of the paper 41 during the conveying process and ensuring the positioning accuracy before cutting.

[0046] The guiding and pressing assembly 2 includes a paper pushing member 21, which is connected to the cutter housing 16 through a paper pushing member mounting rib plate 17 provided in the housing 1. The paper pushing member 21 is arranged near the paper feeding end 164 of the cutter housing 16; the paper pushing member 21 includes a first paper pushing member 21a and a second paper pushing member 21b, which are respectively arranged on the left and right sides of the paper picking member 31. When the paper 41 to be cut enters from the paper picking end 311 towards the cutting blade 321, the first paper pushing member 21a and the second paper pushing member 21b position and guide the paper 41 to be cut towards the cutting blade 321. Through the automatic guiding function of the paper pushing member 21, this design can adapt to papers 41 of different thicknesses and materials. Even thin or thick papers 41 can be effectively controlled, avoiding problems such as jamming of thin papers or difficulty in feeding thick papers, and increasing the versatility of the equipment and the convenience for users.

[0047] The guiding and pressing assembly 2 further includes a paper guiding member 23, which is connected to the cutter housing 16 through a paper guiding member mounting rib plate 18 provided in the housing 1. The paper guiding member 23 is arranged at the front end near the cutting edge 321 of the cutting knife 32.

[0048] The paper guide 23 includes a first paper guide 23a and a second paper guide 23b, which are respectively arranged on the left and right sides of the paper picking member 31. They can accurately guide and position the paper 41 about to enter the cutter area, ensuring that the paper 41 remains centered when finally entering the cutting stage, avoiding cutting deviation, and improving the cutting accuracy and the flatness of the cutting edge of the paper 41. The symmetrical layout of the first paper guide 23a and the second paper guide 23b exerts balanced pressure on the paper 41, ensuring the stability of the paper 41 during high-speed or continuous cutting, preventing the paper 41 from drifting or deviating from the center, and maintaining good control even when handling thin paper or materials with strong sliding properties. When the paper 41 to be cut is introduced from the bottom contact point of the paper pusher 21 towards the cutting edge 321, the first paper guide 23a and the second paper guide 23b are configured to position and introduce the paper 41 to be cut towards the cutting edge 321. The paper guide 23 is provided at the front end of the cutting edge 321 and, in conjunction with the paper pusher 21, forms a smooth introduction channel from the bottom contact point of the paper pusher 21 to the cutting edge 321. This not only makes the introduction of the paper 41 smoother, reducing the risk of the paper 41 being distorted or folded, but also improves the continuity and efficiency of the entire cutting process. The design of the paper guide 23 takes into account the processing requirements of papers 41 with different widths and thicknesses. Its flexible guiding mechanism can adapt to papers 41 of various sizes, enhancing the versatility of the paper cutter and meeting the diverse cutting operation requirements. The precise guiding function of the paper guide 23 reduces the possibility of the paper 41 coming into abnormal contact with the cutter, thereby reducing the risk of the paper 41 being torn or jammed during introduction and cutting, protecting the integrity of the paper 41, and extending the maintenance cycle of the equipment.

[0049] The distance between the first paper pusher 21a and the second paper pusher 21b is greater than the distance between the first paper guide 23a and the second paper guide 23b; when the paper guiding and pressing assembly 2 guides the paper 41 to be cut, a bending stress from the outside to the inside is formed from the pressure contact point between the paper pusher 21 and the corresponding paper 41 to the pressure contact point of the bottom of the paper guide 23 on the paper 41. The gradual compression and precise alignment of the paper 41 during the import process are realized. This design helps the paper 41 to form a flatter and more compact state before entering the cutting knife 32, reduces the deviation during cutting, and improves the cutting accuracy. It is beneficial to further stabilize the traveling trajectory of the paper 41, ensure that the paper 41 maintains the correct guiding and position when entering the cutting area. The bending stress helps to control the bending degree of the paper 41, avoid deviation or wrinkling during high-speed pushing or processing of thicker paper 41, and improve the stability and reliability of the cutting process. The paper 41 can be positioned with the least deformation and the highest flatness before entering the cutting link, reducing the resistance and unnecessary pauses during the cutting process and improving the cutting efficiency. At the same time, the cutting quality problems caused by the unevenness of the paper 41, such as uneven cutting edges or paper scraps, are reduced, thus improving the aesthetics and usability of the finished product. This design adjusts the distance between the paper pusher and the paper guide to adapt to papers 41 of different thicknesses and materials, increasing the adaptability and versatility of the equipment. Whether it is thin paper or thicker cardboard, this design can effectively control and guide them to ensure the consistency of the cutting effect.

[0050] On the lower edges 162 of both side parts 161 near the paper picking end 311, there are smooth paper guiding edges 163 that are bent downward from top to bottom with a positive curvature. The smooth bending design of the paper guiding edge 163, especially its positive curvature form, can provide a natural and continuous guiding surface when the paper 41 is picked up by the paper picking end 311 and guided to move in the direction of the cutting knife 32. Such a design helps the paper 41 to move smoothly along the predetermined path before entering the cutting process, reduces the jamming or folding of the edge of the paper 41, and ensures that the paper 41 can be accurately positioned at the cutting position, improving the preparation efficiency and accuracy of cutting. The paper guiding edge 163 with a positive curvature can contact the edge of the paper 41 in a more gentle way. Compared with an acute angle or right angle design, it can effectively reduce the damage to the paper 41 caused by friction or extrusion during the import process, such as tearing or leaving indentations, thus protecting the integrity of the paper 41, especially suitable for application ranges with high requirements for the appearance of the paper 41. During operation, even if the paper 41 has a certain thickness or a slippery texture, the paper 41 can be more smoothly positioned through the guiding action of the paper guiding edge, reducing the risk of operation errors.

[0051] The lowest point of the pressure guiding component 2 is on the same horizontal plane as the lowest point of the lower edge 162 of the side portion 161. The lowest point of the pressure guiding component 2 is aligned with the lower edge 162 of the side portion 161 of the paper cutter housing 16, forming a flat and continuous paper 41 inlet and outlet channel. This design helps the paper 41 to move smoothly and unobstructed during the inlet and cutting processes, avoiding paper 41 jamming, folding or damage caused by height differences, and improving the smoothness of cutting and the continuity of paper 41 processing. Ensure that the paper 41 remains at a stable horizontal height during the process of being guided by the pressure guiding component 2 into the cutting blade 32, which is crucial for improving cutting accuracy. The flat inlet of the paper 41 reduces the vertical deviation of the cutting position, making the cutting line more accurate and improving the qualification rate and quality of the finished product. The overall structure of the pressure guiding component 2 and the paper cutter housing 16 is more stable, reducing vibrations or unnecessary mechanical wear caused by uneven contact during operation, extending the service life of the equipment, reducing the operating noise at the same time, and improving the stability and durability of the equipment.

[0052] Embodiment 3

[0053] As Figures 7 to 10 shown, according to an embodiment of the present application, wherein Figure 7 is a separation structure for the paper separator and the paper cutter to be used in combination. Figures 8 - 10 A paper separator is provided, having a housing 1, which further includes a paper separator housing 12, which has a hollow structure with an inner diameter larger than the diameter of the paper tube 4 carrying the paper 41 to be cut, ensuring that the paper tube 4 can be stably placed in the paper separator housing 12 and facilitating the smooth entry and exit of the paper 41. The paper tube 4 can freely rotate along its axis in the paper separator housing 12, reducing the blockage of the paper 41 during loading and processing, improving the processing speed and operation efficiency. At the same time, the paper 41 can maintain good flatness before cutting, improving the cutting accuracy. The side wall of the paper separator housing 12 has a paper outlet 13, and the paper 41 to be cut can be pulled out from the paper outlet 13 for cutting, making the positioning and cutting processes of the paper 41 more direct and efficient. In addition, the position design of the paper outlet 13 helps to control the pulling direction and speed of the paper 41, reducing the disorderly movement of the paper 41 before cutting and preventing the paper 41 from being damaged or wrinkled.

[0054] At least one parallel guide rail 11 is provided on the side wall of the paper separator housing 12. The parallel guide rail 11 is parallel to the axis of the paper separator housing 12. At least one parallel guide rail 11 is adjacent to the paper outlet 13. The parallel guide rail 11 can prevent the paper tube 4 from being pulled out from the paper outlet 13 while ensuring smooth paper discharge. Some parallel guide rails 11 provide additional support for the paper 41; some parallel guide rails play a pressure-guiding role for the smooth discharge of the paper 41, preventing the paper 41 from being offset or twisted during the pulling process. In addition, the positioning role of the parallel guide rail 11 increases the stability of the paper 41 before cutting, ensuring the continuity and accuracy of the cutting process. In addition to guiding the paper 41 to be discharged smoothly, the parallel guide rail 11 also prevents the paper tube 4 from being accidentally pulled out from the paper outlet 13. This design detail reflects the consideration of user operation safety, avoids equipment damage or personal injury that may be caused by improper operation, enhances the safety of use, and also improves the user experience.

[0055] A contact plane 10 is provided on the outer wall of the paper separator housing 12, and the contact plane 10 is a contact plane with the placement plane. The contact plane 10 directly contacts the placement plane rather than through sharp edges or points, which can effectively reduce the wear or damage to the placement plane (such as a desktop, a workbench), protect the working environment, and extend the service life. The contact plane 10 can be a supporting surface of the paper separator housing 12 formed by at least two parallel guide rails 11. It can ensure that the paper separator has a more stable contact with the work surface or the placement plane when placed. Its supporting surface increases the overall stability of the equipment, prevents displacement or shaking caused by external forces during operation, thereby ensuring cutting accuracy and operational safety. The parallel guide rails 11 not only serve as a supporting structure, but also as a linear guide device for importing and exporting the paper 41. The parallel guide rails 11 are parallel to the placement plane, ensuring that the paper 41 moves along a straight path when entering and exiting the paper separator, reducing the risk of deflection or paper jams, and improving the smoothness of the paper 41 processing and the accuracy of cutting.

[0056] The inner wall of the paper separator housing 12 has circumferentially arranged inclined strips 14, which utilize the physical contact principle. When the paper 41 in the roll paper tube 4 is drawn out, the paper tube 4 rotates accordingly. During the rotation process, the paper tube 4 contacts the inclined strips 14, and due to the guiding effect of the inclined plane, the paper tube 4 will be guided and pressed against the inner wall of the paper separator housing on the side close to the paper outlet 13. The inclined strips 14 are arranged on the side wall corresponding to the paper outlet 13. When the roll paper tube 4 is pulling out the paper 41, the paper tube 4 rotates inside the paper separator housing 12. When it rotates and rolls to the inclined strips 14, the paper tube 4 will slide down to the inner wall of the paper separator housing 12 on the side close to the paper outlet under the obstruction of the inclined strips 14. This ensures that when the paper 41 is drawn out, the paper tube 4 maintains an optimal positional relationship with the paper outlet 13, facilitating the smooth and accurately positioned pulling of the paper 41 from the paper outlet 13 and avoiding blockage or distortion of the paper 41 during the pulling process. Through the guiding effect of the inclined strips 14, the paper tube 4 can quickly and stably adjust its own position during the rotation process, reducing the resistance during the extraction of the paper 41, making the paper separation process more rapid and continuous, enhancing the user experience, and also improving the overall working efficiency. The design of the inclined strips 14 makes the contact mode between the paper tube 4 and the inner wall of the paper separator housing 12 smoother and more controllable, avoiding wear on the inner wall of the paper tube 4 or the paper separator housing 12 caused by direct friction, and at the same time reducing unnecessary noise, making the equipment operate more quietly and durably. When the user extracts the paper 41, there is no need to exert special effort or perform complex operations. The automatic guiding function of the inclined strips 14 simplifies the operation process, enabling even first-time users to easily get started and enhancing the product's usability. The inclined strips 14 do not depend on the specific size or material of the paper tube 4. The setting of the inclined strips 14 enables the paper separator housing 12 to be compatible with roll paper tubes 4 of various specifications, enhancing the product's versatility and market adaptability.

[0057] There are two inclined strips 14. By arranging at least two inclined strips 14 on the inner wall of the paper separator housing 12, the position adjustment of the paper tube 4 during rotation can be guided more evenly and stably. The layout of two or more inclined strips ensures that no matter where the paper tube 4 rotates to, it can come into contact with the inclined strip 14 in time, so as to be continuously guided, avoiding the random rolling or deviation of the paper tube 4 inside, and improving the stability during the extraction process of the paper 41. The inclined strips 14 are arranged circumferentially along the inner wall of the paper separator housing 12, and the outer shape of the inclined strips 14 is a smooth arc-shaped strip or a wedge-shaped strip. The design of the smooth arc-shaped strip or wedge-shaped strip of the inclined strip 14 reduces the frictional resistance between the paper tube 4 and the inclined strip, making the paper tube 4 roll more smoothly without causing unnecessary pulling or damage to the paper 41, ensuring the continuity and flatness of the paper 41 when it is drawn out of the paper tube 4 and improving the user experience. The circumferentially arranged inclined strips 14 can precisely control the rotation angle and the final stop position of the paper tube 4 in the paper separator housing 12 through their specific shape and position layout, ensuring that the paper 41 can be accurately aligned with the paper outlet 13, facilitating the user to quickly and accurately extract the required length of the paper 41 and improving the accuracy and efficiency of the operation.

[0058] The holding part 15 is connected to the housing 1, and the force application direction to the holding part 15 is perpendicular to the contact plane 10 arranged on the outer wall of the paper separator housing 12. The holding part 15 is directly connected to the housing 1, providing a clear force application point for the user. When using the paper cutting device, the user can apply force more intuitively and conveniently. The connection of the holding part 15 is not limited to being connected to the outer wall of the paper separator housing 12 or the outer wall of the paper cutter housing 16. By simplifying the operation process, the user does not need to find a suitable grasping position and can directly control the paper cutting device stably through the holding part, ensuring that the force line during the user's force application is direct and effective. When pulling the paper 41, the force can be more concentratedly transmitted to the paper tube 4, avoiding the inefficiency or damage to the paper 41 caused by the force dispersion or improper direction, thereby improving the efficiency and accuracy of the paper separation operation.

[0059] Embodiment 4

[0060] As Figures 11 to 17As shown, according to an embodiment of the present application, a paper cutting device is provided, which includes a housing 1. The housing 1 includes a paper separator housing 12, which has a hollow structure; an outlet 13 is provided on the side wall of the paper separator housing 12; the housing 1 further includes a cutter housing 16, which is disposed near the outlet 13 and connected to the outer wall of the paper separator housing 12; the paper separator housing 12 and the cutter housing 16 are integrally connected structures. The cutter assembly 3 includes a paper picking member 31. One end of the paper picking member 31 has a flat and pointed paper picking end 311, and the paper picking end 311 protrudes outward relative to the paper inlet end 164 of the cutter housing 16; the other end of the paper picking member 31 is connected to the cutter housing 16, and a cutter 32 is disposed near the other end of the paper picking member 31. The cutting edge 321 of the cutter 32 corresponds to the traveling direction of the paper 41 to be cut; a guiding and pressing assembly 2 is connected to the inside of the cutter housing 16. When the paper 41 to be cut enters the cutter assembly 3, the guiding and pressing assembly 2 assists in positioning and linearly slides the paper 41 to be cut in the direction of the cutting edge 321. The other end of the paper picking member 31 has an elastic buckle 313, and the cutter housing 16 is provided with an elastic buckle installation groove 19. The other end of the paper picking member 31 is detachably connected through the elastic buckle 313 and the elastic buckle installation groove 19.

[0061] To improve the cutting accuracy and efficiency, the flat and pointed design of the paper picking end 311 can accurately insert under the paper 41, effectively pick up a single sheet of paper 41, and improve the cutting efficiency. At the same time, the alignment design of the cutting edge 321 of the cutter 32 with the traveling direction of the paper 41 ensures a smooth and efficient cutting process, reducing the deviation or damage of the paper 41 during the cutting process. The setting of the guiding and pressing assembly 2 inside the cutter housing 16, by assisting in positioning and guiding the paper 41 to linearly slide in the direction of the cutter 32, not only simplifies the operation process but also ensures the stability and straightness of the paper 41 when it is introduced into the cutting area, avoiding the bending or jamming of the paper 41 and improving the continuity and efficiency of cutting. The design that the paper picking end 311 protrudes outward relative to the paper inlet end 164 of the cutter housing 16 enables the user to more intuitively and safely position and introduce the paper 41 during operation, reducing the risk of fingers touching the cutter, improving the safety of use, and enhancing the user experience. The combined design of the cutter housing 16 and the paper separator housing 12, and the hollow structure of the paper separator housing, ensure the stable placement of the paper tube 4, reduce the vibration and wear of the device during use, and enhance the stability and durability of the overall structure.

[0062] Through the adjustable pressure guiding component 2 and the precisely positioned cutter component 3, it is possible to adapt to papers 41 of different specifications and materials, improving the applicable range of the paper cutter, meeting diverse cutting requirements, and enhancing the versatility of the equipment. In summary, through the carefully designed cutter component, pressure guiding component, and housing structure, the paper cutter effectively improves the cutting accuracy, efficiency, and safety, while ensuring the stable durability and wide applicability of the equipment, providing users with an efficient, safe, and easy-to-operate cutting solution.

[0063] The pressure guiding component 2 includes a paper pushing member 21, which is connected to the paper cutter housing 16 through a paper pushing member mounting rib plate 17 arranged in the housing 1. The paper pushing member 21 is arranged near the paper feeding end 164 of the paper cutter housing 16; the paper pushing member 21 includes a first paper pushing member 21a and a second paper pushing member 21b, which are respectively arranged on the left and right sides of the paper picking member 31. When the paper to be cut enters from the paper picking end 311 towards the cutting edge 321, the first paper pushing member 21a and the second paper pushing member 21b position and guide the paper to be cut towards the cutting edge 321. The pressure guiding component 2 further includes a paper guiding member 23, which is connected to the paper cutter housing 16 through a paper guiding member mounting rib plate 18 arranged in the housing 1. The paper guiding member 23 includes a first paper guiding member 23a and a second paper guiding member 23b, which are respectively arranged on the left and right sides of the paper picking end 311. When the paper to be cut is guided towards the cutting edge 321 from the bottom contact point of the paper pushing member 21, the first paper guiding member 23a and the second paper guiding member 23b position and guide the paper to be cut towards the cutting edge 321. The pressure guiding component 2 can accurately guide and position the paper: ensuring that when the paper to be cut enters the cutter component 3, it can start from the paper picking end 311, through precise guidance and positioning, until it reaches the cutting edge 321. Such a design effectively avoids the deviation or wrinkling of the paper during the conveying process, improving the cutting accuracy and efficiency.

[0064] The first paper pushing member 21a and the second paper pushing member 21b are connected by a fixed shaft member 22. The first paper pushing member 21a and the second paper pushing member 21b are a set of rollers with the same outer diameter; the first paper pushing member 21a and the second paper pushing member 21b can rotate synchronously, which can ensure the synchronous and stable transmission of the paper pushing member 21.

[0065] The first paper guiding member 23a and the second paper guiding member 23b are connected by a fixed shaft member 22. The first paper pushing member 21a and the second paper pushing member 21b are a set of rollers with the same outer diameter. The first paper pushing member 21a and the second paper pushing member 21b can rotate synchronously, which can ensure the synchronous and stable transmission of the paper guiding member 23.

[0066] The first paper pusher 21a and the second paper pusher 21 are designed as rollers with the same outer diameter, and the first paper guide 23a and the second paper guide 23b are designed as rollers with the same outer diameter, which can rotate synchronously, ensuring the smoothness and continuity of the paper during the feeding process, reducing the damage that may be caused by uneven stress on the paper, and at the same time reducing the noise and vibration during the operation of the equipment, improving the stability of the equipment operation.

[0067] The outer diameters of the first paper pusher 21a and the second paper pusher 21b are larger than those of the first paper guide 23a and the second paper guide 23b. The outer diameters of the paper pusher 21 and the paper guide 23 are different during the paper feeding process, and the paper tension can be controlled in sections. Among them, the outer diameter of the paper pusher 21 is larger than that of the paper guide 23, and the paper tension can be gradually adjusted during the paper transmission process, from the stronger guiding force of the paper pusher to the more precise positioning of the paper guide, realizing the sectional optimization of the paper control force, ensuring the smooth feeding of the paper, avoiding unnecessary excessive compression, and protecting the paper quality. When the guide and pressure assembly 2 feeds the paper 41 to be cut, a bending stress from the outside to the inside is formed from the pressure contact point between the paper pusher 21 and the corresponding paper 41 to the pressure contact point of the bottom of the paper guide 23 corresponding to the paper 41. The gradual compression and precise alignment of the paper 41 during the feeding process are realized. It helps the paper 41 to form a flatter and more compact state before entering the cutting knife 32, reducing the deviation during cutting and improving the cutting accuracy. It is beneficial to further stabilize the traveling trajectory of the paper 41, ensure that the paper 41 maintains the correct guiding and position when entering the cutting area, and the bending stress helps to control the bending degree of the paper 41, avoiding deviation or wrinkle during high-speed pushing or processing of thicker paper 41, and improving the stability and reliability of the cutting process. The paper 41 can be positioned with the least deformation and the highest flatness before entering the cutting link, reducing the resistance and unnecessary pauses during the cutting process, and improving the cutting efficiency.

[0068] When the outer diameter of the paper tube 4 is larger than the inner diameter of the paper separator housing 12, the embodiment of the present application also proposes another solution. Figure 16 As shown in the figure, the paper tube 4 is placed outside the paper separator housing 12 and used close to its outer wall. The paper tube 4 is directly placed outside the paper separator housing 12, no longer restricted by the inner diameter size of the housing, greatly expanding the adaptability range of the equipment to different specifications of paper tubes, and improving the versatility and flexibility of the equipment. The parallel guide rails 11 equipped at the bottom of the paper separator housing 12 play a dual role. They not only play a physical support role to prevent the paper tube 4 from rolling or moving, but also help the paper 41 to maintain a flatter state when leaving the paper tube by directly pressing the bottom of the paper tube 4. This can reduce the wrinkles or bending of the paper during the conveying process, and improve the operation efficiency and finished product quality in the subsequent processing process. Figure 16In the usage mode shown, there is no need to precisely match the diameters of the paper tube 4 and the paper separating device housing 12. Just place the paper tube closely against the outer wall of the housing to start the operation, which reduces the operation difficulty and improves the work efficiency.

[0069] The working principle of the paper cutter disclosed in this application: First, as Figure 17 shown, the user places the paper tube containing the paper to be cut into the paper separating device housing 12. The paper separating device housing 12 has a hollow structure with an inner diameter larger than the outer diameter of the paper tube 4, ensuring that the paper tube can be stably placed and rotated. The parallel guide rails 11 can prevent the paper tube 4 from being pulled out from the paper outlet 13 while ensuring smooth paper output. The paper 41 in the paper tube 4 is smoothly pulled out from the bottom of the parallel guide rails 11, and the parallel guide rails 11 press the paper 41 against the placement plane. One end of the paper 41 in the paper tube 4 passes through the paper picking end 311 in a flat and pointed shape, which is convenient for inserting under the paper and gently lifting it to prepare for subsequent cutting. When the paper cutting process is started, the guiding and pressing assembly 2 begins to function. The paper pushing members 21, especially its first paper pushing member 21a and second paper pushing member 21b, are arranged on the left and right sides of the paper picking member 31. By contacting the paper, they smoothly push the paper towards the blade 321. The roller design of the paper pushing members 21 ensures the stability of the paper during the pushing process and reduces friction. At the same time, the synchronous rotation of the paper pushing members 21 ensures the uniform force and straight advancement of the paper, avoiding paper distortion or jamming. As the paper advances forward, the paper guiding members 23 also start to guide the paper. The first paper guiding member 23a and the second paper guiding member 23b are located on both sides of the paper picking end 311. They are also connected by the fixed shaft member 22 and can rotate synchronously, but the outer diameter of the paper guiding members 23 is smaller than the outer diameter of the paper pushing members 21. This design is to further precisely control the position and tension of the paper before the paper enters the cutter assembly 3, ensuring that the paper reaches the cutting point in the best state. When the paper is precisely guided to the position of the cutter 32 by the paper pushing members 21 and the paper guiding members 23, the blade 321 is aligned with the advancing direction of the paper 41. At this time, the paper 41 is quickly and precisely cut, and the cut paper 41 is exported from the first paper outlet slot 165, and the uncut paper 41 is exported from the second paper outlet slot 166; the design and position of the blade 321 ensure the high efficiency of cutting and the neatness of the edge. The entire paper cutting process, through the coordinated action of the carefully designed mechanical structures such as the paper picking end, paper pushing members, paper guiding members, and cutter assembly, realizes the precise introduction, stable advancement, precise cutting, and smooth output of the paper, ensuring high-efficiency and high-quality paper processing effects.
