Description

The present invention relates to the field of apparatus and related accessories for cutting paper, and more particularly to a paper cutting apparatus, a paper lifting member, a paper cutter and a paper separator suitable for separating and cutting packaging paper from rolls of paper.In the traditional paper cutters, the displacement of paper easily occurs during the cutting operation, resulting in low precision of cutting. During the cutting operation, the paper is easily influenced by external factors, resulting in unstable cutting. Existing paper cutters are complicated to operate and require manual adjustment of several components by the user, making the operation difficult. In addition, it is difficult to lift up individual sheets due to the small thickness thereof, resulting in that a plurality of sheets are easily lifted up simultaneously in cutting.The paper cutting device, the paper lifting member, the paper cutter, and the paper separator disclosed in the present application significantly improve the precision and stability of the cutting, simplify the operation flow, increase the applicability, and increase the efficiency of the cutting by the design and arrangement of the paper separating unit, the paper cutting unit, and the paper pressing unit being thought of.The first aspect of the embodiments of the present application provides a paper lifting member suitable for a paper cutting device including a first part and a second part connected to the first part. The end of the first part is provided with a point which can engage under the paper and raise it upwards from the depositing surface. The paper lifting member is provided with a cutter, the blade of the cutter facing the tip.In the paper raising member disclosed in the above embodiments, the tip can easily engage under the paper, thereby stably raising the paper. This prevents the paper from wobbling or shifting during lifting and increases stability during the cutting operation. The cutting edge of the cutting blade points to the tip, whereby the cutting is more concentrated and powerful. This reduces the jitter of the paper during cutting and ensures the stability of the cutting operation. The paper lifting member is capable of matching papers of different thickness and materials. Whether it is single or multi-ply paper, it can be effectively lifted and cut, thereby improving the applicability of the device.The second aspect of the embodiments of the present invention provides a paper cutter comprising a paper cutting unit, the paper cutting unit comprising a paper cutter housing; a paper lifting member connected to the paper cutter housing, a first end of the paper lifting member engageable under the paper to be cut; a slot disposed between the paper lifting member and the paper cutter housing; a cutting blade disposed within the slot and near a second end of the paper lifting member, the cutting blade being mounted in either the paper cutter housing or the paper lifting member, the cutting blade being configured to cut the paper entering from the slot.In the paper cutter provided in the above embodiments, it is ensured by the paper lifting member that the position of the paper is precise upon entering the cutting region. This reduces the possibility of paper deviation and improves the precision of cutting. The configuration of the slot allows the paper to enter the cutting area along a predetermined path. This avoids deviation of the paper during the cutting operation and further increases the precision of the cutting. By having the cutting knife disposed within the slot and proximate the second end of the paper lifting member, it is ensured that the paper is cut immediately after entering the slot. This reduces the movement of the paper during the cutting operation and improves the precision of the cutting. Due to the close interaction between the slot and the cutting blade, the cutting takes place more concentrated and powerful. This reduces the jitter of the paper during cutting and ensures the stability of the cutting operation. The configuration of the slot allows the user to intuitively observe the operation of raising and inserting the paper into the slot, which facilitates the operation. This greatly improves the precision and stability of the cutting, simplifies the operation sequence, increases the applicability, and increases the efficiency of the cutting.The third aspect of the embodiments of the present invention provides a paper separator including a paper separation unit, the paper separation unit including a paper separator housing, the paper separator housing being continuous from a first end to a second end, and a hollow accommodation space being formed between a first side wall and a second side wall extending in the axial direction, and an opening of the accommodation space being in communication with the accommodation space, wherein the paper of the paper roll located in the accommodation space can be pulled out through this opening and separated by the first and / or the second side wall.In the paper separator provided in the above-mentioned embodiments, the configuration of the accommodation space enables the roll of paper to be stably placed therein. This avoids the shifting or wobbling of the paper roll during the paper separating operation, and thus improves the precision of paper separation. The configuration of the first and second side walls allows the paper to be separated along a predetermined path when being pulled out of the opening of the receiving space. This reduces the possibility of paper deviation and further improves the precision of paper separation. Having the paper separator housing continuous from the first to second ends allows the roll of paper to freely rotate within the housing. This ensures the stability of the paper during extraction. The first and second side walls provide not only guidance during paper severing, but also support for the paper roll to prevent slippage or tilting of the paper roll during the paper severing operation. This increases the stability of the paper separating operation.The fourth aspect of the embodiments of the present invention provides a paper cutting device including a paper separating unit, at least one paper cutting unit, and a paper pressing unit, wherein the paper pressing unit is disposed near the slit and connected to the paper cutter housing, the paper pressing unit supportively limits the position of the paper continuously inserted into the slit toward the cutting blade, and presses it downward.In the paper cutting device provided in the above embodiments, the paper pressing unit can supportably limit the position of the paper to be cut, thereby ensuring that the position of the paper is precise upon entering the slit. This reduces the possibility of paper deviation, increases the precision of cutting and improves the stability of the cutting operation. The paper pressing unit continuously introduces the paper into the slot, which ensures the stability of the paper on entering the cutting area and avoids interruptions or blockages of the paper during the cutting operation. By the paper pressing unit continuously introducing the paper into the slot and pressing it downward, it is possible that after each paper raising, the cutting can be performed immediately. This achieves a continuous and efficient cutting operation. The paper cutting device is overall of compact design, in which the individual components cooperate harmonically. This reduces unnecessary operation steps and increases work efficiency.The accompanying drawings of the specification, which form a part of the present disclosure, serve to further understand the present invention.

The paper separator housing 1 of the paper cutter has two open ends and a central portion which is continuous from one of the ends to the other, the central portion defining the entire length of the paper cutter. In the present disclosure, the direction of the length of the center portion is defined as an axial direction, while the direction perpendicular to the placement surface during the operation of the paper cutter is defined as a longitudinal direction. The paper cutting device comprises a paper separating unit, a paper cutting unit and a paper pressing unit, wherein the paper separating unit comprises a paper separator housing 1, and the paper cutting unit comprises a paper cutter housing 6.In some embodiments, in the paper cutting apparatus shown in Figs. 1 to 3 and 4 to 7, the paper lifting member (not shown) is a constituent member of the paper cutter housing (not shown), and the paper cutter housing (not shown) is a constituent member of the paper separator housing 1.In some embodiments, the paper separator housing 1 and the paper cutter housing 6 are detachably connected as shown in Figs. 8 to 16.In some embodiments, the paper separator housing 1 and the paper cutter housing 6 are formed as separate parts which can cooperate as shown in Figs. 19 to 26.In some embodiments, between a first side wall 30 and a second side wall 40 of the paper separator housing 1, there is formed a receiving space 2 capable of receiving a roll of paper as shown in Figs. 1 to 16 and 23 to 26.In some embodiments, the accommodating space 2, the first side wall 30 and its side bottom 9a, the second side wall 40 and its side bottom 9b together constitute the paper separating unit as shown in Figs. 1 to 16 and Figs. 24 to 26. In paper separating, as shown in FIG. 10, when the diameter thereof is smaller than the inner diameter of the accommodating space 2, the roll of paper may optionally be inserted axially into the accommodating space 2. The paper roll can rotate in the circumferential direction of the receiving space 2 and the paper to be cut can be pulled out of the opening 3 of the receiving space. By inserting the paper roll into the receiving space 2 for paper separation, the space utilization is improved, whereby the paper cutting device is more compact and easier to carry.In some embodiments, the paper roll may also be arranged outside the receiving space 2 if its diameter is larger than the inner diameter of the receiving space. In paper separation, the paper to be cut is successively smoothed for paper separation as it passes through the side bottom 9a of the first side wall 30 and the side bottom 9b of the second side wall 40.In some embodiments, as shown in Figs. 1 to 16, the paper to be cut is pulled out from the opening 3 of the accommodation space between the side bottom 9a of the first side wall 30 and the side bottom 9b of the second side wall 40, while being smoothed by the side bottom 9a or 9b. Simultaneously, the desired length of paper is measured and the paper is separated before being cut. The side bottom 9 aof the first side wall 30 or the side bottom 9 bof the second side wall 40 can ensure that the paper roll can be stably placed and unwound during use of the paper cutting device. This improves the stability and precision of cutting and ensures the durability and reliability of the paper cutting device during use. The paper separating unit can effectively separate the paper, thereby ensuring that the paper cut at each cut is neat and uniform, and improving the efficiency and quality of the cutting. The side bottom 9a of the first side wall 30 and the side bottom 9b of the second side wall 40 of the paper separator housing 1 form a supporting structure. The side floors 9a and 9b, which are located at the lowest point of the supporting structure, are arranged on the same plane. The support structure allows the paper cutter to not tilt or shake during use, thereby ensuring that the paper is evenly loaded on both sides as the paper cutter moves to cut the paper. In moving the paper cutter during use, the support structure reduces the problem of excessive pressure on certain areas of the paper and ensures the stability of the paper cutter during set-up.In some embodiments, as shown in Figs. 8 to 16, the paper cutting apparatus further comprises four support rollers 91, the four support rollers 91 being mounted on the side bottoms of the first side wall 30 and the second side wall 40 of the paper separator housing 1, and the lowermost positions of the four support rollers 91 being arranged on the same plane. In paper separation, the support rollers 91 support the first side wall 30 or the second side wall 40 for paper separation. In the paper cutting, the support rollers 91 can reduce friction between the paper cutting device and the work table, so that the paper cutting device can easily move and simultaneously adapt to work tables having different heights and flatness, thereby increasing applicability and flexibility of the device and simultaneously reducing noise generated when the paper cutting device is moved.In some embodiments, the paper cutter is provided with a paper cutter unit disposed near the side bottom 9a of the first side wall 30 of the paper separator housing 1, as shown in Figs. 1 to 3.As shown in Figs. 1 to 16, the paper cutting unit comprises a slit 8 and a paper lifting member 50, a first end of the paper lifting member 50 is a tip 11, the slit 8 is disposed in the paper separator housing 1 near the side bottom corresponding to the first side wall 30, and the slit 8 extends axially from the first end 10 of the paper separator housing 1. It is easier for the tip 11 to engage under the paper to be cut and lift it up.The tip 11 can lift the paper more easily. Particularly, when the paper is thin or stuck together, the tip 11 can be easily inserted under the paper and separate it.In some embodiments, the paper separator housing 1 includes a first tip 11a and a second tip 11b as shown in Figs. 4 to 16, wherein the first tip 11a is disposed at an end of the paper separator housing 1 located under the opening of a first slot 8a, respectively, and the second tip 11b is disposed at an end of the paper separator housing 1 located under the opening of a second slot 8b, respectively. The tips 11a and 11b can more conveniently insert the paper into the slits during operation, reduce the manual effort for separating the paper, improve the ease of operation and the efficiency of operation, and thus ensure smooth entry of the paper into the cutting area, which reduces the failure rate.In some embodiments, the tips 11, 11a, 11b project outwardly relative to the first end 10 of the paper cutter housing 6, as shown in Figs. 1-3 and 8-16. By having the tips 11, 11a, 11b project outwardly, the visibility of the tip 11 of the paper cutter is increased when it grasps under the paper, so that in use the entry position and the state of the paper can be seen more clearly. This can more easily insert the paper into the slits during operation, reduce the manual labor for separating the paper, improve the ease of operation and the efficiency of operation, and thus ensure smooth entry of the paper into the cutting area, reducing the failure rate.In some embodiments, the cutting edge of the cutting blade 4 is disposed within the slot 8, as shown in Figs. 1 to 16, wherein the cutting blade 4 is configured to cut the paper entering the slot 8 from the first end 10 of the paper separator housing 1. The slot 8 can guide the paper along a predetermined path into the cutting area to ensure the precision and consistency of the cutting. By the arrangement of the slit 8, the paper can be allowed not to shift during the cutting operation, thereby improving the cutting effect.In some embodiments, as shown in Figs. 4 to 7, the cutter blades 4a and 4b are integrally formed with the paper separator housing 1, and the cutter blades 4a and 4b are formed inside the paper separator housing 1 during the production of the paper cutter.In some embodiments, as shown in Figs. 1 to 3 and 8 to 16, the cutter blade 4 and the paper separator housing 1 are formed together into a detachable structure, and the cutter blade is detachably mounted via a blade mounting recess 16 disposed in the paper separator housing 1. The user can thereby easily disassemble and replace the cutter without sending it for repair or purchasing a new paper cutter, thereby saving cost and time. Due to the detachable structure, the user can regularly replace the worn cutting blade or remove the cutting blade for cleaning. This helps remove paper residue and other contaminants from the cutter, maintain the sharpness and cleanliness of the cutter, and improve the quality and efficiency of the cutting. The service life of the entire paper cutting device is thereby extended. This not only reduces the overall maintenance cost of the apparatus, but also ensures the long term performance and reliability of the paper cutting apparatus.In some embodiments, as shown in FIGS. 1-3, the cutting blade 4 may be a separately used wallt blade or other blade suitable for the blade mounting recess 16. The cutter blade 4 can be removed for separate use, which not only facilitates renewal but also increases the functionality, applicability, range of application and flexibility of the apparatus with respect to the tool.In some embodiments, the paper cutting device is provided with two paper cutting units as shown in Figs. 4 to 11, the two paper cutting units being separately disposed respectively on the side bottom 9a of the first side wall 30 and on the side bottom 9b of the second side wall 40 of the paper separator housing 1. A left paper cutting unit is arranged on the first side wall 30, a right paper cutting unit is arranged on the second side wall 40, wherein the left paper cutting unit and the right paper cutting unit are arranged in an axially symmetrical manner. Here, the left paper cutter unit includes a first slit 8a axially extending from a first end 10 of the paper separator housing 1 for paper feeding, and a first cutter blade 4a disposed in the paper separator housing 1. The cutting edge of the first cutting blade 4a faces the opening of the first slit 8a, and the angle and position of the cutting edge which comes into contact with the paper can be adjusted, thereby improving the quality of the cutting. The first cutter blade 4a is adapted to cut the paper entering from the opening of the first slot 8a. The right paper cutter unit includes a second slit 8b axially extending from the first end 10 of the paper separator housing 1, and a second cutter blade 4b disposed in the paper separator housing 1. The cutting edge of the second cutting blade 4b faces the opening of the second slit 8b, and the angle and position of the cutting edge which comes into contact with the paper can be adjusted, thereby improving the quality of the cutting. The second cutter blade 4b is adapted to cut the paper entering from the opening of the second slot 8b. In use, some people are accustomed to using the left hand while others prefer the right hand. The left and right paper cutting units in this embodiment can be adapted to different hand habits.In some embodiments, the paper cutting device is provided with two paper cutting units as shown in Figs. 12 to 14, the two paper cutting units being separately disposed respectively on the side bottom 9a of the first side wall 30 and on the side bottom 9b of the second side wall 40 of the paper separator housing 1. In order to meet different hand habits, a left paper cutting unit is arranged on the first side wall 30 and a right paper cutting unit is arranged on the second side wall 40, wherein the left and right paper cutting units are arranged centrosymmetrically. Here, both the left and right paper cutting units of the paper cutting apparatus shown in Figs. 12 to 13 are suitable for right-handed persons. In the centrosymmetrically arranged paper cutting device shown in FIG. 14, both the left and the right paper cutting units are suitable for left-handed persons.In some embodiments, four paper cutting units are provided as shown in Figs. 15 to 16, and these four paper cutting units may be disposed on the first side wall 30 and the second side wall 40, respectively, and in the vicinity of their respective side bottoms 9a and 9b. The first side wall 30 is provided with two left paper cutting units, the second side wall 40 with two right paper cutting units, wherein the two right paper cutting units on the second side wall 40 are simultaneously suitable for both left-handed and right-handed persons. The slot 8a and the slot 8b may guide the paper along a predetermined path into the cutting area to ensure the precision and consistency of the cutting. The first slit 8 aand the second slit 8 bextending axially can ensure that the paper does not shift during the cutting operation, thereby improving the cutting effect and reducing waste generation. The cutter blades 4a and 4b are detachably mounted in the paper separator housing 1 to ensure safety during use and to prevent accidental injuries. The paper cutting units on each side may share a cutting blade 4a or 4b. The first cutter blade 4a and the second cutter blade 4b of the paper cutter units are fixedly disposed in the paper separator housing 1, i.e., the paper separator housing 1 and the paper cutter units are formed as an integral structure.In some embodiments, the paper separator housing 1 and the paper cutter units are formed with each other as a detachable structure as shown in Figs. 8 to 16, i.e., the sub-housing of the paper cutter unit may be detachably separated from the paper separator housing 1. The first cutter blade 4a or the second cutter blade 4b may be inserted in advance into the provided slot of the cutter unit sub-housing before the cutter unit sub-housing is attached to the cutter housing 1.In some embodiments, the paper cutting device further comprises a paper pressing unit as shown in Figs. 1 to 3, wherein the paper pressing unit supportively limits the position of the paper continuously inserted toward the cutting blade 4 into the slit 8 and presses it downward. In this embodiment, the paper pressing unit is a paper pressing stand plate 7, the paper pressing stand plate 7 being connected to the outer wall of the paper separator housing 1 and the paper pressing stand plate 7 at least partially covering the corresponding slot 8. The paper pressing standing plate 7 helps to control the feeding path of the paper and reduce skew of the paper during the cutting operation. The paper pressing standing plate 7 can bend the paper inserted into the slit into an arcuate surface, so that the paper passing through the slit achieves greater rigidity and tension before reaching the blade of the blade cutter.In some embodiments, the paper cutting device further comprises paper pressing units as shown in Figs. 4 to 16, the paper pressing units supportingly limiting the position of the paper continuously inserted toward the cutting blades 4a and 4b into the slits 8a and 8b and pressing them downward. In this embodiment, the paper pressing units are paper pressing stand plates 7 aand 7 b, wherein the first paper pressing stand plate 7 ais arranged on the outer wall of the first side wall 30 and covers at least partially the first slot 8 a, and the second paper pressing stand plate 7 bis arranged on the outer wall of the second side wall 40 and covers at least partially the second slot 8 b. The paper pressing standing plates 7a and 7b extend downward to partly cover the slits 8a and 8b so that a gap remains between the paper pressing standing plates 7a and 7b and the slits 8a and 8b, respectively, the gap between the paper pressing standing plates 7a and 7b and the slits 8a and 8b contributing to control the feeding path of the paper and reducing skew of the paper during the cutting operation. The paper pressing standing plates 7a and 7b can bend the paper inserted into the slit into an arcuate surface, so that the paper passing through the slits achieves greater rigidity and tension before reaching the blade of the cutter blade. The paper pressing standing plates 7a and 7b can hold the outwardly extending paper pressed down so as to enter the slits 8a and 8b toward the cutter blade 4. This ensures that the paper remains flat during the cutting operation, the jitter and the displacement of the paper are reduced, and the precision and quality of the cutting are improved. The paper pressing standing plates 7a and 7b can prevent the paper from curling or folding upon entering the slits 8a and 8b, ensure the flatness of the paper, and increase the cutting effect. In operation, the paper pressing stand plates 7a and 7b can better control the paper entry and improve the operating convenience and efficiency. The paper pressing standing plates 7 aand 7 bmay prevent the penetration of fingers or foreign matter into the slits and enhance safety during use.In some embodiments, as shown in FIGS. 1 to 3, the paper cutting unit further includes an upper guide ramp 13 and a lower guide ramp 12, the lower guide ramp 12 being disposed at a location of the paper separator housing 1 that is located below the opening of the slot 8, respectively, and the lower guide ramp 12 being disposed inclined outwardly and downwardly from the slot 8. The lower guide ramp 12 smoothly guides the paper into the slot 8 to ensure that the paper does not deviate from the predetermined path upon entering the slot. This increases the precision of cutting, reduces the resistance of the paper to enter the slot, and improves the ease of operation and efficiency of operation.The upper guide ramp 13 is disposed at a position of the first side wall 30 located above the opening of the slot 8, respectively, and the upper guide ramp 13 is disposed inclined outward and upward relative to the slot 8. The upper guide ramp 13 can smoothly guide the paper into the slot 8 to ensure that the paper does not deviate from the predetermined path upon entering the slot. This increases the accuracy and consistency of paper entry into the slot 8, which in turn improves the precision and quality of the cutting.In some embodiments, the first side wall 30 includes a first lower guide ramp 12a disposed at a location of the paper separator housing 1 that is located below the opening of the first slot 8a, respectively, and the first lower guide ramp 12a is disposed inclined outward and downward relative to the first slot 8a; the second side wall 40 includes a second lower guide ramp 12b disposed at a location of the paper separator housing 1 that is located below the opening of the second slot 8b, and the second lower guide ramp 12b is disposed inclined outward and downward relative to the second slot 8b, as shown in Figs. 4 to 16.The lower guide ramps 12a and 12b can smoothly guide the paper into the slots 8a and 8b and ensure that the paper does not deviate from the predetermined path upon entering the slots. This increases the precision of cutting, reduces the resistance of the paper to enter the slits, and improves the ease of operation and efficiency of operation. The lower guide ramps 12a and 12b can prevent the paper from jamming as it enters the slots 8a and 8b, thereby reducing the failure rate. The lower guide ramps 12a and 12b facilitate alignment of the paper with the slits 8a and 8b and improve ease of use and consistency.In some embodiments, as shown in Figs. 17 to 23, the paper pressing unit comprises a paper cutter housing 6 and side portions 61 on the left and right sides, a guide roller assembly connected to the paper cutter housing 6 and disposed between the side portions 61 on the left and right sides. As the paper to be cut enters the slot 8, the guide roller assembly assists in restricting and pushing down the position of the paper 70 to be cut linearly slidably inserted toward the blade 44. The paper pressing unit not only simplifies the inserting steps of the paper 70, but automatically restricts and presses down the position of the linearly slidably inserted paper when the paper 70 enters the paper lifting member 50. This significantly improves the ease of operation, reduces the effort for manual operation, and increases the working efficiency.As shown in Figs. 17 to 18, the upper surface from the tip 11 of the paper lifting member 50 to the blade 44 forms a contact support surface 14 for the paper 70 to be cut. the contact support surface 14 serves as a smoothly transitioning surface which helps the paper 70 to transition smoothly from the tip 11 to the blade 44, thereby reducing the folding or displacements of the paper 70 during transportation and ensuring the positioning accuracy before cutting.As shown in Figs. 19 to 23, the paper pressing unit comprises a paper pushing member 21 connected to the paper cutter housing 6 via a paper pushing member mounting plate 67 disposed in the paper separator housing 1. The paper pushing member 21 is disposed near a paper feeder 64 of the paper cutter housing 6. The paper pushing member 21 includes a first paper pushing member 21 aand a second paper pushing member 21 bdisposed on the left and right sides of the paper raising member 50, respectively. When the paper 70 to be cut enters from the tip 11 toward the blade 44, the first paper pushing member 21 aand the second paper pushing member 21 bposition and guide the paper 70 to be cut toward the blade 44.When the paper 70 to be cut is inserted into the slit 8, the first paper pushing member 21 aand the second paper pushing member 21 bpress the paper 70 to be cut downward and guide it toward the cutting blade 4. This avoids problems such as jamming of thin paper or difficulty in inserting thick paper and increases the applicability of the device and the user's comfort.As shown in Figs. 19 to 23, the paper pressing unit further comprises a paper guide member 23 connected to the paper cutter housing 6 via a paper guide member mounting plate 68 disposed in the paper separator housing 1. The paper guide member 23 is disposed in front of and near the blade 44 of the cutter 4. The paper guide member 23 includes a first paper guide member 23 aand a second paper guide member 23 bdisposed on the left and right sides of the paper raising member 50, respectively. They allow the paper 70 that will enter the cutting area to be accurately guided and positioned to ensure that the paper 70 remains finally centered in the cutting phase. This avoids cutting variations and improves the precision of cutting and the straightness of the cut edges of the paper 70. the symmetrical arrangement of the first paper guide member 23a and the second paper guide member 23b applies uniform pressure to the paper 70 to ensure the stability of the paper 70 during the high-speed or continuous cutting operation and to avoid drifting or deviating of the paper 70 from the center. Even when handling thin paper or high lubricity materials, control remains effective. When the paper 70 to be cut is inserted toward the cutter 44 from a contact point on the lower surface of the paper pushing member 21, the first paper guide member 23 aand the second paper guide member 23 bposition and guide the paper 70 to be cut toward the cutter 44. This not only allows smoother insertion of the paper 70, thereby reducing the risk of twists or folds of the paper 70, but also increases the continuity and efficiency of the entire cutting process. This embodiment of the paper guide element 23 takes into account the requirements for processing paper 70 of different width and thickness. Its flexible guiding mechanism can adapt to different sizes of the paper 70, which increases the applicability of the paper cutting device and meets the requirements for a variety of cutting operations. The precise guidance of the paper guide member 23 reduces the possibility of abnormal contact between the paper 70 and the cutter blade, thereby reducing the risk of the paper 70 tearing or jamming during insertion and cutting. This protects the integrity of the paper 70 and extends the maintenance intervals of the apparatus.As shown in Figs. 19 to 23, the distance between the first paper pushing member 21a and the second paper pushing member 21b is larger than the distance between the first paper guiding member 23a and the second paper guiding member 23b. During the insertion of the paper 70 to be cut, the paper pressing unit generates an outward-inward bending stress extending from the pressure contact point of the paper pushing member 21 with the corresponding paper 70 to the pressure contact point of the lower surface of the paper guide member 23 with the corresponding paper 70. This allows for a step-by-step pressing and precise alignment of the paper 70 during the insertion process. This configuration contributes to the paper 70 being in a flatter and more compact state before being inserted into the cutting blade 4, thereby reducing variations in cutting and increasing the precision of cutting. It promotes further stabilization of the travel path of the paper 70 and ensures that the paper 70 retains the proper guidance and position upon entry into the cutting area. The bending stress helps control the bending angle of the paper 70, and prevents shifting or folding in fast feed or processing of thicker paper 70, which improves the stability and reliability of the cutting operation. Before the paper 70 enters the cutting operation, it can be positioned with minimal deformation and maximum flatness, which reduces resistance and unnecessary interruptions during the cutting operation and increases the efficiency of the cutting. At the same time, the quality problems of cutting caused by unevenness of the paper 70, such as uneven cutting edges or generation of paper dust, are reduced, thereby improving the aesthetic and utility of the final product. This configuration adjusts the distance between the paper pusher member and the paper guide member to accommodate paper 70 of varying thickness and materials, which increases the adaptability and applicability of the device. Whether thin paper or thicker cardboard, this configuration allows effective control and guidance to ensure consistency of the cutting action.As shown in Figs. 17 to 23, the lower edges 62 of the two side portions 61 near the tip 11 each have a smooth positively curved paper guide edge 63 from top to bottom. The smoothly curved configuration of the paper guide edge 63, particularly its positive curvature, provides a natural and continuous guide surface when the paper 70 is lifted from the tip 11 and guided toward the cutter blade 4. This configuration helps the paper 70 to move smoothly along a predetermined path prior to the cutting operation, thereby minimizing jamming or folding of the edges of the paper 70. This ensures that the paper 70 is accurately and correctly positioned in the cutting position, improving the efficiency and precision of cutting. The positively curved paper guide edge 63 can more gently contact the paper 70 at its edges. Compared to sharp or rectangular designs, it can effectively avoid damage such as cracks or printing spots that might arise from friction or pressure during the introduction of the paper 70, thereby preserving the integrity of the paper 70. This is particularly suitable for applications in which there are high requirements for the appearance of the paper 70. In operation, even with paper 70 having a certain thickness or smooth texture, by guiding the paper guide edge, the paper 70 can be positioned more stably, thereby reducing the risk of misoperation.As shown in Figs. 17 to 23, the deepest point of the paper pressing unit and the deepest point of the lower edge 62 of the side portion 61 are on the same horizontal plane. By having the deepest point of the paper pressing unit flush with the lower edge 62 of the side portion 61 of the paper cutter housing 6, a planar and continuous feed-in and feed-out channel for the paper 70 is formed. This avoids the entanglement, folding or damage of the paper 70 due to differences in height and improves the smoothness of cutting and the continuity of processing of the paper 70. it is essential that the paper 70 always remains at a stable horizontal height while being guided from the paper pressing unit to the cutter blade 4 to increase the precision of cutting. The planar introduction of paper 70 reduces the height variation at the cutting position, so that the cut line becomes more precise and the success rate and quality of the finished products is improved. The entire structure of the paper pressing unit and the paper cutter housing 6 is more stable, reducing vibration or unnecessary mechanical wear due to uneven contact during operation. This extends the life of the device, simultaneously lowers the operating noise level and increases the stability and durability of the device.In some embodiments, as shown in Figs. 8 to 16, the paper cutter further comprises a grip portion 60, the grip portion 60 being connected to the paper separator housing 1 to provide a clear force application point to the user, whereby the user can exercise force intuitively and easily when using the paper cutter. When a force is applied to the handle portion 60, at least one of its force directions perpendicular to the shelf surface is in contact with the paper cutter. This ensures that the paper cutting device does not deviate laterally from the predetermined cutting path during the cutting process on account of an exerted force. It is not limited to this that the grip portion 60 is connected to the outer wall of the paper separator housing 1 or the paper cutter housing 6. The grip portion 60 simplifies the operation in that the user does not have to search for an appropriate grip position and can stably control the paper cutting device directly over the grip portion, which ensures that the line of action of the force exerted by the user is direct and effective. When pulling out the paper 70, the force may be more concentratedly transmitted to the paper roll to avoid distribution of the force or improper direction, which may result in inefficiency or damage to the paper 70, and thus increase the efficiency and accuracy of paper separation.In some embodiments, as shown in Figs. 19 to 23, the paper cutter device further comprises a grip portion 60 connected to the outer wall of the paper cutter housing 6. The grip portion simplifies the operation in that the user does not have to search for an appropriate grip position and can stably control the paper cutting device directly over the grip portion, which ensures that the line of action of the force exerted by the user is direct and effective. The direction of force on the handle portion 60 is perpendicular to the paper 70. The paper cutting unit and the paper separating unit are separated, whereby the user can exert more intuitive and comfortable force when using the paper cutting device. When pulling out the paper 70, the force applied to the grip portion 60 can be more concentratedly transmitted to the roll of paper to avoid distribution of the force or improper direction, which might result in inefficiency or damage to the paper 70, and thus increase the efficiency and accuracy of paper separation.In some embodiments, as shown in Figs. 1 to 7, a non-slip corrugation 18 is provided on the outer wall of the paper separator housing 1 of the paper cutter, and this non-slip corrugation 18 can significantly increase the friction on the outer wall of the paper separator housing 1. When operating the paper cutting device, in particular when a greater cutting force is required, the non-slip corrugation 18 can ensure that the user's hand does not slip off. The hand can grip the cutter more firmly without requiring excessive effort to maintain the grip. This reduces the load on the hand and wrist, reduces inaccuracies in cutting or injuries due to slipping off, increases the stability and safety of the operation, and thus improves the stability of the handle.In some embodiments, as shown in Figs. 8 to 16, the paper separator housing 1 further comprises a first upper guide ramp 13a and a second upper guide ramp 13b. The first upper guide ramp 13a is disposed at a position of the first side wall 30 which is located above the opening of the first slot 8a, respectively, and the first upper guide ramp 13a is disposed inclined outward and upward relative to the first slot 8a. The first upper guide ramp 13 atogether with the first lower guide ramp 12 aform an extended opening of the first slot 8 a. The second upper guide ramp 13 bis disposed at a position of the second side wall 40 located above the opening of the second slot 8 b, respectively, and the second upper guide ramp 13 bis disposed inclined outward and upward relative to the second slot 8 b. The second upper guide ramp 13 btogether with the second lower guide ramp 12 bform an extended opening of the second slot 8 b.By the fact that the first upper guide ramp 13 aand its corresponding first lower guide ramp 12 a, and the second upper guide ramp 13 band its corresponding second lower guide ramp 12 bform respectively widened openings, the inlet openings of the first slot 8 aand of the second slot 8 bare enlarged. This allows the paper to enter the slits more easily and reduces problems such as jamming of the paper or difficulty in alignment due to too small entrance openings. The upper guide ramps 13a and 13b can smoothly guide the paper into the slots 8a and 8b and ensure that the paper does not deviate from the predetermined path upon entering the slots. This increases the accuracy and consistency of paper entry into the slots, which in turn improves the precision and quality of the cutting. The upper guide ramps 13a and 13b reduce the resistance of the paper as it enters the slots, thereby more easily guiding the paper into the slots. This improves the ease of operation and the operating efficiency, and reduces the difficulty of operation for the user. The enlarged apertures prevent the paper from jamming upon entering the slots and assure smooth entry into the cutting area, thereby reducing the failure rate and thus increasing the reliability and stability of the apparatus.In some embodiments, the cutting edge of the cutting blade forms with the side edges of the slit 8 a rhombic clearance 5, 5a or 5b as shown in Figs. 1 to 3 and 10 to 11. As the paper to be cut approaches the cutter blade 4, the paper slides upward along the cutting edge of the cutter blade 4 with the contact with the cutter blade 4. At this moment, the rhombic clearance 5, 5a or 5b can distribute the stress acting on the cutting point, thereby decreasing the concentration of the stress. This makes the cut edges of the paper more stable and reduces the risk of deformation and tearing.Embodiment 2As shown in Figs. 17 to 22, the embodiments of the present invention disclose a paper lifting member 50 optionally connected to the paper cutter housing 6. The tip 11 of the paper lifting member 50 can engage under the paper to be cut. The tip 11 projects outwardly relative to the paper feeder 64 of the paper cutter housing 6. As shown in Figs. 24 to 25, a specific structure of the paper lifting member 50 comprises a first part 50a and a second part 50b connected to the first part 50a. The first part 50 aof the paper raising member 50 has an elongated shape and can ensure the accurate positioning of the paper 70 during the cutting operation. The end of the first part 50 aof the paper raising member 50 is a flat-pointed tip 11, and by the flat-pointed configuration, the tip 11 can be accurately inserted under the paper 70 to minimize the damage to the surface of the paper 70. Particularly, in the case of damage-prone or high-gloss paper 70, the integrity of the paper 70 can be effectively protected to ensure that the cut edges of the paper 70 are smooth and burr-free, and to improve the quality of the cutting.The tip 11 can engage under the paper 70 to be cut and lift it from the tray surface. The blade mounting recess 16 of the paper lifting member 50 is provided with a cutter 4. The cutting blade 4 is disposed in the second part 50 bof the paper lifting member 50, and the blade 44 of the cutting blade 4 faces the tip 11. The cutting edge 44 of the cutting blade 4 is opposed to the moving direction of the paper 70 to be cut, which ensures that the straightness and precision of cutting are maintained at a certain angle both in the straight cutting and in the cutting. This is suitable for the cutting requirements of papers 70 of different sizes and types, thereby improving the applicability and adaptability of the paper lifting member 50.The upper surface from the tip 11 of the paper raising member 50 to the blade 44 forms a contact support surface 14, the contact support surface 14 being an arcuate surface and serving to contact and support the paper 70 upward.The contact support surface 14 of the paper lifting member 50 is formed as an arcuate surface which, after lifting the paper 70, provides supporting points which are distributed over a large area and uniformly to ensure that the paper 70 remains in a stable state before cutting. This prevents displacements or vibrations during the cutting operation, thus improving the precision of cutting and the flatness of the paper 70. The arcuate contact support surface 14 will better conform to the paper 70, whether thin paper or thicker cardboard, and provide good support. This ensures consistency during the cutting operation and a wide range of applications.The blade 44 of the blade 4 is inclined relative to the contact support surface 14, which assists the paper 70 from being naturally drawn towards the blade 44 during insertion. This reduces the cutting resistance, making the cutting operation smoother and at the same time ensuring that the cut line is clean and clean, and improves the overall quality and efficiency of the cutting. Preferably, the direction of inclination of the blade 44 forms an angle of 45° to 135° with the plane of the direction of insertion of the paper 70 to be cut. The preferred configuration with an angle in the range of 45° to 135° can significantly improve the efficiency of the cutting process and the quality of the cut surface. Within this angular range, the blade can penetrate the paper with minimal resistance, thereby reducing deformation of the paper and the formation of paper residue during cutting. This results in smoother and more uniform cut edges, thereby improving the aesthetic and performance of the final product. By selecting an appropriate angle, the force and power consumption required for cutting can be reduced and the running cost of the apparatus can be lowered.At the same time, an appropriate tilt angle can optimize the force distribution on the cutting blade, reduce friction and wear between the blade and the paper, extend the life of the cutting blade, and reduce maintenance costs. Within this angular range, stable contact between the blade and the paper is promoted during the cutting operation, thereby preventing the blade from jumping or deviating, and ensuring the rectilinearity and accuracy of the cut line. Particularly in continuous high-speed cutting operations, this configuration can improve the stability and consistency of the entire production process.Embodiment 3As shown in Figs. 17 to 23, the embodiments of the present invention disclose a paper cutter comprising a paper cutter housing 6, a paper lifting member 50 and a paper pressing unit, wherein the paper lifting member 50 is connected to the paper cutter housing 6, and the tip 11 of the paper lifting member 50 can engage under the paper 70 to be cut and lift it up. By allowing the tip 11 to precisely separate and lift the paper 70 up from the stack, it is ensured that only a single sheet of paper is cut each time, thereby avoiding errors such as simultaneously cutting multiple sheets of paper and improving the precision of the cutting. The paper lifting member 50 is provided near its second end with a cutter blade 4, the blade 44 of the cutter blade 4 being opposed to the moving direction of the paper 70 to be cut, ensuring the continuity and efficiency of the cutting operation. The second end of the paper lifting member 50 has a spring presser 15 and the paper cutter housing 6 is provided with a spring presser mounting slot 17, the second end of the paper lifting member 50 being connected to the paper cutter housing by the cooperation of the spring presser 15 with the spring presser mounting slot 17.At the left and right sides of the paper cutter housing 6, there are downwardly extending side portions 61, and the lower edges 62 of the side portions 61 on both sides can press down the both sides of the paper 70 to be cut lifted by the paper lifting member 50. Thereby, the raised paper 70 is firmly pressed onto the deposition surface before cutting, which effectively prevents the paper 70 from moving or corrugating during cutting. This ensures the stability of the cutting operation and thus improves the flatness of the cut edges as well as the overall quality of the cutting. The second end of the paper lifting member 50 is connected to the paper cutter housing 6. The cut paper 70 is separated into two sheets at the second end of the paper lifting member 50. Along with the pressing function of the side portions 61, the risk for the operator to directly contact the cutter blade is reduced, thereby enhancing safety in use. At the same time, the operating process is simplified in that the user merely has to insert the paper 70, while the remaining positioning and pressing processes are automatically carried out by the device.The paper pressing unit is connected to the paper cutter housing 6 and is disposed between the side portions 61 on the right and left sides. Upon entry of the paper 70 to be cut into the paper lifting member 50, the paper pressing unit positions and linearly slidably introduces the paper 70 to be cut toward the cutter 44. The paper pressing unit not only simplifies the inserting steps of the paper 70, but automatically positions and linearly slidably inserts the paper as the paper 70 enters the paper lifting member 50. This significantly improves the ease of operation and the degree of automation, reduces the effort for manual operation, and increases the working efficiency.The tip 11 protrudes outward relative to the paper feeder 64 of the paper cutter housing 6, which can optimize the feeding operation of the paper. The outward protrusion of the tip 11 facilitates the insertion of the paper 70 into the paper lifting member 50, so that the user does not have to slide the paper 70 cumbersomely into a narrow space. This greatly improves user-friendliness.The upper surface from the tip 11 to the blade 44 forms a contact surface 14 for the paper 70 to be cut, and the contact surface 14 serves as a smooth transitional surface which helps the paper 70 to smoothly transition from the tip 11 to the blade 44, thereby reducing the folding or shifting of the paper 70 during transportation and ensuring the positioning accuracy before cutting.The paper pressing unit comprises a paper pushing member 21 connected to the paper cutter housing 6 via a paper pushing member mounting plate 67 disposed in the paper separator housing 1. The paper pushing member 21 is disposed near a paper feeder 64 of the paper cutter housing 6. The paper pushing member 21 includes a first paper pushing member 21 aand a second paper pushing member 21 bdisposed on the left and right sides of the paper raising member 50, respectively. When the paper 70 to be cut enters from the tip 11 toward the blade 44, the first paper pushing member 21 aand the second paper pushing member 21 bposition and guide the paper 70 to be cut toward the blade 44. This avoids problems such as jamming of thin paper or difficulty in inserting thick paper and increases the applicability of the device and the user's comfort.The paper pressing unit further comprises a paper guide member 23 connected to the paper cutter housing 6 via a paper guide member mounting plate 68 disposed in the paper separator housing 1. The paper guide member 23 is disposed in front of and near the blade 44 of the cutter 4. The paper guide member 23 includes a first paper guide member 23 aand a second paper guide member 23 bdisposed on the left and right sides of the paper raising member 50, respectively. They allow the paper 70 that will enter the cutting area to be accurately guided and positioned to ensure that the paper 70 remains finally centered in the cutting phase. This avoids cutting variations and improves the precision of cutting and the straightness of the cut edges of the paper 70. the symmetrical arrangement of the first paper guide member 23a and the second paper guide member 23b applies uniform pressure to the paper 70 to ensure the stability of the paper 70 during the high-speed or continuous cutting operation and to avoid drifting or deviating of the paper 70 from the center. Even when handling thin paper or high lubricity materials, control remains effective. When the paper 70 to be cut is inserted toward the cutter 44 from a contact point on the lower surface of the paper pushing member 21, the first paper guide member 23 aand the second paper guide member 23 bposition and guide the paper 70 to be cut toward the cutter 44. This not only allows smoother insertion of the paper 70, thereby reducing the risk of twists or folds of the paper 70, but also increases the continuity and efficiency of the entire cutting process. This embodiment of the paper guide element 23 takes into account the requirements for processing paper 70 of different width and thickness. Its flexible guiding mechanism can adapt to different sizes of the paper 70, which increases the applicability of the paper cutter and meets the requirements for a variety of cutting operations. The precise guidance of the paper guide member 23 reduces the possibility of abnormal contact between the paper 70 and the cutter blade, thereby reducing the risk of the paper 70 tearing or jamming during insertion and cutting. This protects the integrity of the paper 70 and extends the maintenance intervals of the apparatus.The distance between the first paper pushing member 21a and the second paper pushing member 21b is larger than the distance between the first paper guiding member 23a and the second paper guiding member 23b. During the insertion of the paper 70 to be cut, the paper pressing unit generates an outward-inward bending stress extending from the pressure contact point of the paper pushing member 21 with the corresponding paper 70 to the pressure contact point of the lower surface of the paper guide member 23 with the corresponding paper 70. This allows for a step-by-step pressing and precise alignment of the paper 70 during the insertion process. This configuration contributes to the paper 70 being in a flatter and more compact state before being inserted into the cutting blade 4, thereby reducing variations in cutting and increasing the precision of cutting. It promotes further stabilization of the travel path of the paper 70 and ensures that the paper 70 retains the proper guidance and position upon entry into the cutting area. The bending stress helps control the bending angle of the paper 70 and prevents shifting or folding in fast feed or thicker paper processing, which improves the stability and reliability of the cutting operation. Before the paper 70 enters the cutting operation, it can be positioned with minimal deformation and maximum flatness, which reduces resistance and unnecessary interruptions during the cutting operation and increases the efficiency of the cutting. At the same time, the quality problems of cutting caused by unevenness of the paper 70, such as uneven cutting edges or generation of paper dust, are reduced, thereby improving the aesthetic and utility of the final product. This configuration adjusts the distance between the paper pusher member and the paper guide member to accommodate paper 70 of varying thickness and materials, which increases the adaptability and applicability of the device. Whether thin paper or thicker cardboard, this configuration allows effective control and guidance to ensure consistency of the cutting action.The lower edges 62 of the two side sections 61 close to the tip 11 each have a paper guide edge 63 which is positively curved smoothly from top to bottom. The smoothly curved configuration of the paper guide edge 63, particularly its positive curvature, provides a natural and continuous guide surface when the paper 70 is lifted from the tip 11 and guided toward the cutter blade 4. This configuration helps the paper 70 to move smoothly along a predetermined path prior to the cutting operation, thereby minimizing jamming or folding of the edges of the paper 70. This ensures that the paper 70 is accurately and correctly positioned in the cutting position, improving the efficiency and precision of cutting. The positively curved paper guide edge 63 can more gently contact the paper 70 at its edges. Compared to sharp or rectangular designs, it can effectively avoid damage such as cracks or printing spots that might arise from friction or pressure during the introduction of the paper 70, thereby preserving the integrity of the paper 70. This is particularly suitable for applications in which there are high requirements for the appearance of the paper 70. In operation, even with paper 70 having a certain thickness or smooth texture, by guiding the paper guide edge, the paper 70 can be positioned more stably, thereby reducing the risk of misoperation.The deepest point of the paper pressing unit and the deepest point of the lower edge 62 of the side portion 61 are located on the same horizontal plane. By having the deepest point of the paper pressing unit flush with the lower edge 62 of the side portion 61 of the paper cutter housing 6, a planar and continuous feed-in and feed-out channel for the paper 70 is formed. This avoids the entanglement, folding or damage of the paper 70 due to differences in height and improves the smoothness of cutting and the continuity of processing of the paper 70. it is essential that the paper 70 always remains at a stable horizontal height while being guided from the paper pressing unit to the cutter blade 4 to increase the precision of cutting. The planar introduction of paper 70 reduces the height variation at the cutting position, so that the cut line becomes more precise and the success rate and quality of the finished products is improved. The entire structure of the paper pressing unit and the paper cutter housing 6 is more stable, reducing vibration or unnecessary mechanical wear due to uneven contact during operation. This extends the life of the device, simultaneously lowers the operating noise level and increases the stability and durability of the device.Embodiment 4As shown in Figs. 23 to 26, in some embodiments of the present invention, there is further disclosed a paper separator comprising a paper separating unit, the paper separating unit having a paper separator housing 1 having a hollow structure with an inner diameter larger than the diameter of the paper roll 80 carrying the paper 70 to be cut. This ensures that the paper roll 80 can be stably placed in the paper separator housing 1 and that the paper roll 80 can freely rotate along its axis in the paper separator housing 1 while smoothly feeding in and out the paper 70. This reduces the blocking of the paper 70 during the loading and processing operation and improves the processing speed and the operation efficiency. At the same time, the good flatness of the paper 70 before cutting can be maintained, which improves the cutting accuracy. The side wall of the paper separator housing 1 is provided with an opening 3 of the receiving cavity. The paper 70 to be cut can be cut after being pulled out from the opening 3 of the receiving space, whereby the positioning and cutting operation of the paper 70 are performed more directly and efficiently. In addition, the arrangement of the opening 3 of the receiving space helps control the drawing direction and speed of the paper 70, reduce the random movement of the paper 70 before cutting, and prevent the damage or the folding of the paper 70.The outer wall of the paper separator housing 1 is provided with a supporting structure 9 which is in contact with the deposition surface. The support structure 9 forms a surface that directly contacts the shelf surface rather than over sharp edges or points, whereby wear or damage to the shelf surface (e.g., table top, work surface) can be effectively reduced. This protects the working environment and extends the service life. The support structure 9 comprises a support surface. It can ensure more stable contact between the paper separator and the work surface when it is placed. The support surface increases the stability of the entire apparatus and prevents displacements or wobbles by external forces during operation, thereby ensuring the precision of cutting and the operational reliability.The inner wall of the paper separator housing 1 is provided with a circumferentially arranged bevel 90 and the paper roll 80 is rotated along according to the principle of physical contact when the paper 70 is pulled out of the paper roll 80. During rotation, the paper roll 80 comes into contact with the bevel 90. By the guiding action of the slope, the paper roll 80 is guided and abutted against a side of the inner wall of the paper separator housing which is located near the opening 3 of the receiving space. The inclined strip 90 is arranged on the side wall opposite the opening of the receiving space 3. When the paper 70 is pulled out from the paper roll 80, the paper roll 80 rotates in the paper separator housing 1, and when the paper roll 80 rolls up to the slope 90, it slides to the side of the inner wall of the paper separator housing 1 near the outlet opening by the protrusion 90, thereby ensuring that when the paper 70 is pulled out, the paper roll 80 remains in an optimum positional relationship with the opening 3 of the receiving space, thereby enabling smooth and precise pulling out of the paper 70 from the opening 3 of the receiving space and avoiding the blocking or deformation of the paper 70 when it is pulled out. By the guiding action of the skew bar 90, the paper roll 80 can adjust its position quickly and stably upon rotation, thereby reducing the resistance to pulling the paper 70 and making the separating operation of the paper 70 faster and more continuous. This improves the user experience and simultaneously increases overall work efficiency. The arrangement of the bevel 90 enables more uniform and controlled contact between the paper roll 80 and the inner wall of the paper separator housing 1, thereby avoiding direct abrasion which may lead to wear of the paper roll 80 or the inner wall of the paper separator housing 1. At the same time, unnecessary noise is reduced, which makes the apparatus run more quietly and longer-lived. When the paper 70 is pulled out, no particular effort or complicated operation is required. The automatic guidance of the inclined strip 90 simplifies the operating sequence, so that even inexperienced users can handle it without problems. The user-friendliness of the product is thereby increased. The skew bar 90 does not depend on a particular size or material of the paper roll 80. By the placement of the skew bar 90, the paper separator housing 1 can be compatible with various specifications of the paper rolls 80, thereby improving the applicability and marketability of the product.Preferably, two inclined rails 90 are provided, both of which are disposed on the inner wall of the paper separator housing 1, which can more uniformly and stably control the positional displacement of the paper roll 80 during its rotation. The arrangement of the two or more skew bars ensures that the paper roll 80 can contact the skew bars 90 in time and be continuously guided regardless of the location to which it rotates. This prevents the paper roll 80 from rolling or slipping in an uncontrolled manner inside and increases the stability of the extraction of the paper 70. the inclined strips 90 are arranged along the inner wall of the paper separator housing 1 in the circumferential direction. The inclined strips 90 are designed as a smooth arcuate strip or wedge-shaped strip. By forming the ramp 90 as a smooth arcuate ledge or wedge shaped ledge, frictional resistance between the paper roll 80 and the ramp ledges is reduced so that rolling of the paper roll 80 is more smooth and the paper 70 is not unnecessarily pulled or damaged. This ensures the continuity and flatness of the paper 70 when it is pulled out of the paper roll 80 and improves the user experience.
