If the verticality of the paper does not meet the standard (the industry standard is 0.003 in / in), it may cause the edge of the paper to be skewed when cut. You can solve this problem by testing the verticality of the paper by printing on one side of the paper, then turning the paper over and printing on the other side. If the printout is tilted upward on one side and tilted downward on the other side, the verticality of the paper may affect the cutting results‌1.

[0032] ‌Manual feed issues‌: When using manual feed, if the paper does not feed into the printer correctly, it can also cause the edge of the paper to be skewed when cut. Make sure that when manually feeding, the edge of the paper is aligned with the paper guide on the left side of the slot, and the printer will detect and pull the paper from the manual feed slot‌ 1.

[0033] ‌Worn printer parts‌: If the printer's pickup roller is damaged or badly worn, it can also cause the edge of the paper to tilt when cutting. Checking and replacing the worn pickup roller can solve this problem‌2.

[0034] Solutions to solve the problem of the printer cutting the paper at an angle include:

[0035] ‌Check and adjust paper verticality‌: Use standard quality paper and make sure that the paper verticality meets industry standards.

[0036] ‌Use manual feed correctly‌: When feeding paper manually, make sure the paper is fed into the printer correctly and align the paper guides.

[0037] ‌Replace worn parts‌: Regularly check and replace worn parts such as the pickup roller to ensure the normal operation of the printer.

[0038] The above method can effectively solve the problem of the tilted edge of the paper cut by the printer and ensure the printing quality.

[0039] In summary, the present invention has the following beneficial effects compared with the prior art:

[0040] The present invention solves the deficiencies existing in the existing cutting devices.

[0050] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] See also Figure 1-Figure 9 The present invention provides an angle adjustment method comprising the following steps:

[0052] A structure for preventing cutting deformation, comprising a cutting device 1, wherein a fixed knife assembly 2 and a cutting drive assembly 3 are arranged in the cutting device 1, wherein a movable blade 4 is arranged on the cutting drive assembly 3, wherein two height control mechanisms 5 for respectively driving the height positions of both ends of the movable blade 4 are arranged on the cutting drive assembly 3, wherein a first stabilizing adjustment assembly 6 is arranged between the height control mechanism 5 and the cutting drive assembly 3, wherein a second stabilizing adjustment assembly 7 is arranged between the first stabilizing adjustment assembly 6 and the cutting drive assembly 3, and wherein a centering holding structure 8 is arranged between the movable blade 4 and the cutting drive assembly 3;

[0053] The traditional cutter is composed of a housing, a transmission module, a cutter module, a sensor module, a woven belt, and a paper guide. Before the substrate passes through the paper path, the inclined design mechanism of the paper guide is used to compensate for the non-vertical cutting caused by the substrate swinging up and down in the paper path; this invention changes the non-vertical cutting of the substrate by scissors;

[0054] When using a scissor-type cutter to cut, and the border is particularly soft, the soft border is easy to arch when starting to cut at the front end. However, since the paper feeding channel has a certain distance, the border will form one high and one low when being cut and the distance is long, and the border will not be vertical after being cut.

[0055] The traditional cutter is composed of a housing, a transmission module, a cutter module, a sensor module, a woven belt, and a paper guide. The cutter is now widely used in the printer industry and needs to be applicable to a variety of consumables. The inclination angle of the movable blade 4 is adjusted according to the characteristics and materials of the cutting medium 400:

[0056] Adjusting the operation of the first stabilizing adjustment component 6 by controlling the second stabilizing adjustment component 7;

[0057] The height control mechanism 5 on the corresponding side is adjusted by the working adjustment of the first stabilizing adjustment component 6;

[0058] The paper medium enters from the cutting device 1;

[0059] The paper medium is cut by the cooperation of the movable blade 4 and the fixed knife assembly 2;

[0060] However, the material in some specific consumables is very soft, and it is easy to deform or tilt the interface when cutting with a scissors-type cutter. Therefore, it is necessary to design a cutter compensation structure to ensure smooth cutting. When cutting materials of different media, the compensation angle of the cutter is also different: according to the characteristics and material of the cutting medium, the cutting inclination angle of the movable blade 4 is adjusted, and the inclination adjustment is achieved by adjusting the height position on both sides of the movable blade 4; the centering holding structure 8 ensures that any height position adjusted at both ends of the movable blade 4 will make the middle position centered; the cutting device 1 of the present invention includes a cutting component housing 101, and a paper passing channel 102 is arranged in the cutting component housing 101, and the paper passing channel 102 is arranged between the fixed knife assembly 2 and the cutting drive assembly 3, and a paper guide 103 is arranged on the paper passing channel 102.

[0061] The cutting drive component 3 of the present invention includes a lifting drive mechanism 301 arranged in the cutting component housing 101, and a lifting mounting plate 302 is arranged on the lifting drive mechanism 301. The lifting mounting plate 302 is arranged above the paper feeding channel 102, and the lifting mounting plate 302 and the lifting drive mechanism 301 are fixedly connected by screws.

[0062] The fixed blade assembly 2 of the present invention comprises a fixed blade disposed below the paper passage 102; the fixed blade and the movable blade 4 cooperate to cut the paper medium;

[0063] The movable blade 4 and the fixed blade are made of metal material.

[0064] The height control mechanism 5 of the present invention comprises a rectangular opening 501 arranged on the lifting installation plate 302, a lifting control member 502 is movably arranged in the rectangular opening 501, two driving shafts 503 are symmetrically arranged on the surface of the movable blade 4 with the center of the movable blade 4 as the central axis, a transverse straight slot 504 is arranged on the lifting control member 502, and the driving shaft 503 is movably inserted into a corresponding one of the transverse straight slots 504;

[0065] When the lifting control member 502 is adjusted in height, the horizontal straight slot 504 is driven to follow the height adjustment, and the driving shaft 503 on the corresponding side is driven to adjust the height position through the horizontal straight slot 504;

[0066] The lifting control member 502 is adjusted along the height direction, and when adjusted, the horizontal straight slot 504 inside will be driven to follow the height position change;

[0067] During the change process, the driving shaft 503 is pushed to move up and down, so that the height of the driving shaft 503 and the horizontal straight slot 504 are kept synchronous;

[0068] The driving shaft 503 can move left and right in the corresponding transverse straight slot 504 when adjusting the height.

[0069] The first stable adjustment component 6 of the present invention includes a screw sleeve mounting seat 601 arranged above the rectangular opening 501, a screw sleeve mounting groove is arranged in the screw sleeve mounting seat 601, an adjusting screw sleeve 602 is rotatably installed in the screw sleeve mounting groove, a through hole is penetrated from top to bottom in the screw sleeve mounting seat 601, an adjusting screw 603 is arranged on the lifting control member 502, the adjusting screw 603 passes through the through hole from bottom to top, the adjusting screw 603 passes through the adjusting screw sleeve 602, and the adjusting screw 603 and the adjusting screw sleeve 602 are threadedly connected.

[0070] The second stable adjustment component 7 of the present invention includes a transverse worm mounting seat 701 arranged on the outside of the screw sleeve mounting seat 601, an adjusting worm 702 is rotatably installed in the transverse worm mounting seat 701, an adjusting worm 703 is arranged on the circumferential outer wall of the adjusting screw sleeve 602, and the adjusting worm 702 is connected to a corresponding one of the adjusting worm wheels 703.

[0071] When the adjusting worm wheel 703 performs circular rotation, it will perform threaded engagement with the adjusting worm wheel 703 on the adjusting screw sleeve 602, so that the rotation of the adjusting worm 702 is converted into the vertical rotation of the adjusting worm wheel 703;

[0072] The above structure is used to adjust the rotation angle, which effectively improves the angle stability of the worm gear 703;

[0073] That is, when the adjusting worm 702 can only adjust the rotation angle of the adjusting worm wheel 703, the adjusting worm 702 can also limit the angle adjustment of the adjusting worm wheel 703, and the adjusting worm wheel 703 cannot reversely adjust the angle of the adjusting worm 702, which greatly improves stability.

[0074] Furthermore, the centering retaining structure 8 includes a centering shaft 801 arranged in the middle of the movable blade 4 , and a centering vertical groove 802 is arranged in the middle of the lifting mounting plate 302 , and the centering shaft 801 is movably inserted into the centering vertical groove 802 .

[0075] The movable blade 4 in the figure is made of metal material, and the movable blade 4 can also be replaced with different materials. Different movable blades can be replaced according to actual processing requirements;

[0076] Storage environment: Paper cutter blades should be stored in a cool and dry place to prevent oxygen in the air from oxidizing and blunting the blades. It is best to use the box provided by the paper cutter supplier when storing to ensure that the blade does not come into contact with other objects to avoid affecting the working efficiency of the blade.

[0077] Lubrication and maintenance: When using a paper cutting blade, you should insist on using a roller shoulder to scrape the felt, and drip an appropriate amount of lubricating oil upward every day to keep the blade clean and form a thin oil film between the blade and the felt to improve the wear resistance of the blade surface.

[0078] ‌Cleaning and Maintenance‌: After each use, the paper cutter should be cleaned to ensure that the inside of the machine is clean and to avoid the influence of dust and impurities on the machine. In addition, regularly check whether the mechanical blade V-belt, handle, knob, and button are damaged. If the mechanical blade is severely worn, it should be replaced in time.

[0079] ‌Transportation and handling‌: During transportation and handling, the paper cutting blades should be packed in suitable boxes and foam plastics to prevent the die cutting blades from shifting or being damaged during transportation. The words "consumable parts" should be marked on the surface of the box to draw attention‌.

[0080] Safe operation: During operation, the operation procedures should be strictly followed to avoid unauthorized personnel operating the equipment. The machine should be shut down when people leave to ensure safe use of the equipment;

[0081] According to the use requirements, the materials of the adjusting worm 702 and the adjusting worm wheel 703 can be changed:

[0082] Common materials for worm gears

[0083] Carbon steel and alloy steel: Generally, worms can be made of carbon steel such as 45 and 40, which are quenched and tempered to a hardness of 220-250 HBS. For high-speed and heavy-loaded worms, alloy steels such as 20Cr and 20CrMnTi are commonly used, carburized and quenched to 56-62 HRc, or 40Cr, 38SiMnMo and other steels are surface-quenched to 45-55 HRC and should be ground.

[0084] Common materials for worm gears

[0085] ‌ Bronze ‌: Common bronze materials include cast tin bronze (such as ZCuSn10P1, ZCuSn5Pb5Zn5) and aluminum iron bronze (such as ZCuAl10Fe3). Cast tin bronze has good anti-adhesion and wear resistance, and is suitable for high-speed important occasions; aluminum iron bronze has sufficient strength and impact resistance, but poor cutting performance and anti-adhesion performance, and is not suitable for high-speed use.

[0086] ‌Cast Iron‌: Gray cast iron is mainly used in low-speed and light-load situations.

[0087] Principles of material selection

[0088] Sufficient strength: Ensure that the worm and worm wheel will not undergo plastic deformation or breakage during transmission.

[0089] ‌Good anti-friction and wear resistance‌: reduce friction loss and extend service life.

[0090] ‌Good anti-gluing property‌: prevents gluing at high speeds‌.

[0091] Transmission efficiency and application scenarios of worm and worm gear

[0092] ‌Cylindrical worm‌: Suitable for general transmission needs, relatively simple processing.

[0093] ‌Arc cylindrical worm‌: high efficiency, strong load-bearing capacity, small size, light weight, suitable for high load and high speed transmission.

[0094] ‌Toroidal worm gear‌: Smooth transmission, suitable for occasions requiring high-precision transmission‌.

[0095] The inner end of the adjusting worm 702 of the present invention is provided with a limited rotor, the inner end of the transverse worm mounting seat 701 is provided with a rotor limited slot, the limited rotor and the rotor limited slot cooperate to limit the axial movement of the adjusting worm 702, and the outer end of the adjusting worm 702 is provided with a knob structure;

[0096] A scale structure is provided between the knob structure and the side wall of the lifting mounting plate 302;

[0097] The scale structure includes an angle scale mark arranged on the side wall of the lifting mounting plate 302, and the outer circumferential wall of the knob structure is provided with a pointer structure for cooperating with the angle scale mark to prompt the inclination angle of one end of the movable blade 4.

[0098] There are several reasons why the printer cuts the paper at an angle:

[0099] ‌Paper problem‌: The paper you are using may not meet the printer's specifications, such as being too thin or too thick, incorrect size, damp, curled, or damaged, which may cause paper jams or inaccurate cutting.‌

[0100] ‌Feed roller problem‌: If the feed roller is worn or dirty, the paper will not be able to enter the printer normally, thus affecting the cutting effect.

[0101] ‌Problems inside the printer‌: The accumulation of dust and paper scraps inside the printer will affect paper feeding and cutting. It is very necessary to clean the inside of the printer regularly‌.

[0102] Installation problem: Improper installation of paper in the paper box, such as the limit card is not properly locked or there are foreign objects in the paper box, can also cause inaccurate cutting.

[0103] Solutions to these problems include:

[0104] ‌Check the paper‌: Make sure the paper meets the printer's specifications and is not damp, curled, or damaged‌.

[0105] ‌Clean the paper feed roller‌: Use a clean cloth or cotton swab dipped in a small amount of alcohol and gently wipe the surface of the paper feed roller to remove dirt and restore its friction‌.

[0106] ‌Clean the inside of the printer‌: After turning off the printer power, open the front cover or back cover, carefully remove the jammed paper, and use a clean cloth or vacuum cleaner to clean the dust and paper scraps inside the printer‌.

[0107] ‌Adjust the paper position‌: Make sure the paper fits neatly in the input tray and that the edges do not extend beyond the edge of the tray‌.

[0108] ‌Update Driver‌: Regularly check and update your printer's driver to ensure the proper functioning of your printer‌.

[0109] The above method can effectively solve the problem of printer cutting paper at an angle.

[0110] in Fig. 9 Shown is the extra area after cropping.

[0111] In order to improve the flatness of the cut paper, the following methods can also be used to solve the problem:

[0112] ‌Paper verticality issue‌: The verticality of the paper may affect the printer's cutting results. If the verticality of the paper does not meet the standard (the industry standard is 0.003 in / in), it may cause the edge of the paper to be skewed when cut. You can solve this problem by testing the verticality of the paper by printing on one side of the paper, then turning the paper over and printing on the other side. If the printout is tilted upward on one side and tilted downward on the other side, the verticality of the paper may affect the cutting results‌1.

[0113] ‌Manual feed issues‌: When using manual feed, if the paper does not feed into the printer correctly, it can also cause the edge of the paper to be skewed when cut. Make sure that when manually feeding, the edge of the paper is aligned with the paper guide on the left side of the slot, and the printer will detect and pull the paper from the manual feed slot‌ 1.

[0114] ‌Worn printer parts‌: If the printer's pickup roller is damaged or badly worn, it can also cause the edge of the paper to tilt when cutting. Checking and replacing the worn pickup roller can solve this problem‌2.

[0115] Solutions to solve the problem of the printer cutting the paper at an angle include:

[0116] ‌Check and adjust paper verticality‌: Use standard quality paper and make sure that the paper verticality meets industry standards.

[0117] ‌Use manual feed correctly‌: When feeding paper manually, make sure the paper is fed into the printer correctly and align the paper guides.

[0118] ‌Replace worn parts‌: Regularly check and replace worn parts such as the pickup roller to ensure the normal operation of the printer.

[0119] The above method can effectively solve the problem of the tilted edge of the paper cut by the printer and ensure the printing quality.

[0120] The following is the adjustment method for the tilt angle compensation of the cutting tool:

[0121] Step 1: Rotate the adjusting worm 702, and the adjusting worm 702 rotates in coordination with the adjusting worm wheel 703, so that the adjusting worm wheel 703 rotates on different axes. After the adjustment is completed, the height position of the lifting control member 502 is prevented from being automatically adjusted.

[0122] Step 2: When the adjusting worm wheel 703 rotates, the corresponding adjusting screw sleeve 602 is driven to rotate accordingly. When the adjusting screw sleeve 602 rotates, it cooperates with the corresponding adjusting screw 603 to change the height position of the adjusting screw 603. When the adjusting screw sleeve 602 rotates, its axial position is limited by the screw sleeve mounting seat 601. After the adjustment is completed, the height position of the lifting control member 502 is further prevented from being automatically adjusted.

[0123] Step 3: When the adjusting screw 603 is adjusting the height, the lifting control member 502 on the corresponding side is pulled to adjust the height. During the height adjustment process, the lifting control member 502 drives the horizontal straight slot 504 to follow the height adjustment, and drives the driving shaft 503 on the corresponding side to adjust the height through the horizontal straight slot 504;

[0124] Step 4: When the height of the driving shaft 503 at one side is adjusted and the driving shaft 503 at the other end is in a fixed state, the movable blade 4 will be tilted at one side;

[0125] Step 5: According to the characteristics and requirements of the cutting medium, the tilt angle of the movable blade 4 is adjusted to ensure qualified cutting.

[0126] The main reasons why the printer's scissor cutter easily deforms or tilts the media during cutting include the following:

[0127] ‌Design and manufacturing accuracy of scissor cutters‌: The design and manufacturing accuracy of scissor cutters directly affects their cutting effect. If the cutting edge of the cutter is not sharp enough or the cutting edge is not smooth, the media will be deformed or tilted during cutting‌1.

[0128] Wear and aging during use: As the use time increases, the cutting edge of the cutter will gradually wear out, resulting in reduced cutting effect and the media is prone to deformation or tilting. 1.

[0129] ‌Media quality and thickness‌: Different media quality and thickness have different requirements for the cutter. If the media is too thick or uneven in texture, the cutter may lose control during cutting, causing the media to deform or tilt‌1.

[0130] Solutions to these problems include:

[0131] ‌Check and maintain the cutter regularly‌: Check the cutting edge of the cutter regularly to see if it is sharp. Sharpen or replace the cutter if necessary to ensure the cutting effect.

[0132] Adjust the pressure and angle of the cutter: By adjusting the pressure and angle of the cutter, the cutter can be more stable during cutting and the deformation or tilt of the media can be reduced.

[0133] ‌Choose the right media‌: Choose the right media according to the printer's requirements and avoid using media that is too thick or has uneven texture to ensure the cutting effect.

[0134] Through the above method, the problem that the printer's scissor cutter easily deforms or tilts the media during cutting can be effectively solved, thereby ensuring printing quality and efficiency.

[0135] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected.
