[0019] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] As Figure 1 - Figure 9As shown in the figure, a self-grinding cutter for paper processing proposed by the present invention includes a cutting assembly 1, a mounting box 3, a processing table 4 and a knife sharpening assembly 5. A cutting groove is opened at the central position of the processing table 4. A back plate 401 is fixedly installed on the top back surface of the processing table 4. Installation frames 405 are fixedly installed on both sides of the back surface of the back plate 401. A threaded rod 407 is installed between the installation frames 405 through bearings. One end of the threaded rod 407 extends out of the installation frame 405 and is installed with a screw motor 408. A limiting rod 406 is installed below the threaded rod 407. The processing table 4 can provide an installation position for the surrounding components and can provide a placement position for the paper, facilitating the device to perform automatic cutting and processing on the paper. The back plate 401 can provide an installation position for the surrounding components and cooperate with the mounting plate 404 to guide the paper on the top of the processing table 4, so that the paper can move towards the blade 107 under the guidance of the first guide roller 301 and the second guide roller 302, thereby realizing the cutting of the paper. The installation frame 405 can provide an installation position for the threaded rod 407, the limiting rod 406 and the screw motor 408. The threaded rod 407 can rotate and then cooperate with the threaded hole inside the sliding table 101, so that the cutting assembly 1 slides on the outside of the threaded rod 407 and the limiting rod 406. The limiting rod 406 can limit the sliding table 101, thereby improving the stability of the sliding table 101 and its surrounding components during horizontal movement. The screw motor 408 adopts the YE3-100KW type. After the screw motor 408 is powered on, it can rotate, thereby driving the threaded rod 407 to rotate at a constant speed, facilitating the adjustment of the position of the cutting assembly 1; A mounting box 3 is fixedly installed on one side of the bottom of the processing table 4. A ventilation groove is opened on one side of the mounting box 3 to facilitate the vacuum pump 303 to suck the air inside the mounting box 3, the first guide roller 301 and the second guide roller 302, so as to form a negative pressure environment inside the first guide roller 301 and the second guide roller 302, so as to utilize the negative pressure inside the first guide roller 301 and the second guide roller 302 to generate suction on the paper, thereby guiding the paper to move and folding the paper on one side of the blade 107, facilitating batch cutting of the paper; Two groups of guide assemblies 2 are fixedly installed at the position of the cutting groove on the top of the processing table 4. The guide assemblies 2 can guide the blade 107 to roll stably, so as to ensure that the blade 107 is always in a vertical state when contacting the paper, avoiding the blade 107 from skewing during the cutting process and affecting the cutting effect of the paper; A cutting component 1 is movably installed on the back of the processing table 4. The cutting component 1 includes a sliding table 101. A first installation bin 109 is fixedly installed on the top of the sliding table 101, and a second installation bin 105 is fixedly installed on the bottom of the sliding table 101. The cutting component 1 can perform batch cutting on paper, thus replacing manual labor, ensuring the cutting effect of the paper, and improving the efficiency of paper cutting. The sliding table 101 can slide horizontally on the outer sides of the threaded rod 407 and the limiting rod 406, thereby driving the components around the sliding table 101 to move horizontally, facilitating the movement of the blade 107 to one side of the paper and enabling the blade 107 to continuously apply pressure to the paper to complete the cutting. The first installation bin 109 and the second installation bin 105 can respectively provide installation positions for the internal components, so that the blades 107 are arranged in a ring inside the cutting component 1 and the blades 107 roll at a constant speed to achieve the cutting of the paper; A knife sharpening component 5 is fixedly installed inside the first installation bin 109 and the second installation bin 105. The knife sharpening component 5 can polish the front and back sides of the blade 107 while the blade 107 rolls at a constant speed. On the one hand, it can remove the impurities on the surface of the blade 107, and on the other hand, it can ensure that the cutting edge is corrected to a straight state before the blade 107 contacts the paper, thus ensuring the cutting effect of the blade 107 on the paper and also eliminating the need for equipment shutdown maintenance operations, improving the efficiency of the device for paper processing.

[0021] Furthermore, the knife sharpening component 5 includes a bottom plate 503. Two electromagnetic guide rails 502 are fixedly installed on one side of the top of the bottom plate 503, and two mounting rods 505 are fixedly installed on the other side of the top of the bottom plate 503. The top of the electromagnetic guide rails 502 and the mounting rods 505 is fixedly installed with a top plate 507. A main control box 506 is fixedly installed on the side of the mounting rod 505 away from the electromagnetic guide rail 502. The bottom plate 503 can provide installation positions for the components on the top. The electromagnetic guide rails 502 can drive the slider 501 to move longitudinally by magnetic force, thereby respectively adjusting the angles of the first grinding plate 504 and the second grinding plate 508 so that the first grinding plate 504 and the second grinding plate 508 are respectively in contact with the front and back sides of the cutting edge, thus realizing the grinding of the cutting edge. The mounting rod 505 can provide installation positions for the main control box 506 and the mounting seat 509. The top plate 507 can fixedly connect the top of the electromagnetic guide rails 502 and the mounting rods 505, so that the bottom plate 503, the electromagnetic guide rails 502, the mounting rods 505 and the top plate 507 form a frame structure, improving the overall stability of the knife sharpening component 5. The main control box 506 can be connected to the electromagnetic guide rails 502 through wires, thereby respectively controlling the installation angles of the first grinding plate 504 and the second grinding plate 508 through the electromagnetic guide rails 502 to realize the adjustment of the grinding effect of the blade 107; A first grinding plate 504 is installed between the electromagnetic guide rail 502 and the mounting rod 505, and a second grinding plate 508 is installed between another set of electromagnetic guide rail 502 and the mounting rod 505. The first grinding plate 504 is installed above the blade 107, and the second grinding plate 508 is installed below the blade 107. Connecting pieces 510 are fixedly installed at both ends of the first grinding plate 504 and the second grinding plate 508. A slider 501 is installed at one end of the first grinding plate 504 and the second grinding plate 508 close to the electromagnetic guide rail 502, and a mounting seat 509 is installed at one end of the first grinding plate 504 and the second grinding plate 508 close to the mounting rod 505. Grinding grooves are provided on the surfaces of the first grinding plate 504 and the second grinding plate 508. When the blade 107 contacts the first grinding plate 504 and the second grinding plate 508, the front and back surfaces of the blade 107 can be ground to ensure the cutting effect of the blade 107 during subsequent use. The connecting piece 510 can be axially connected to the slider 501 and the mounting seat 509 respectively. Thus, when the slider 501 slides up and down, the installation angles of the first grinding plate 504 and the second grinding plate 508 can be adjusted.

[0022] Further, the guiding component 2 includes a mounting shaft frame 206. A first limiting roller 201 is fixedly installed on one side of the mounting shaft frame 206, and a fixing frame 202 is installed at one end of the first limiting roller 201 away from the mounting shaft frame 206. A second limiting roller 204 is installed below the first limiting roller 201, and a limiting frame 205 is installed at one end of the second limiting roller 204 away from the mounting shaft frame 206. A limiting piece 203 is fixedly installed between the limiting frame 205 and the fixing frame 202, and a number of through holes are formed inside the limiting piece 203. The mounting shaft frame 206 can provide a mounting position for the surrounding components. The first limiting roller 201 and the second limiting roller 204 cooperate to limit the blade 107 in the horizontal direction. Thus, when the blade 107 passes through the inside of the guiding component 2, it can always be in a vertical state to cut the paper, thereby ensuring the cutting effect of the device on the paper. The limiting frame 205 and the fixing frame 202 respectively limit one end of the second limiting roller 204 and the first limiting roller 201, and provide a mounting position for the limiting piece 203. The limiting piece 203 is made of a flexible material with high strength elasticity, such as rubber and silica gel. During the paper cutting process, on the one hand, it can prevent the operator's hand from reaching into the cutting position and causing injury, improving the safety of the device during operation. On the other hand, during cutting, the two limiting pieces 203 apply pressure to the paper, tightly pressing the paper together, which facilitates the blade 107 to cut the paper and improves the stability of the paper during the cutting process.

[0023] Further, a threaded hole and a through hole are formed inside the sliding table 101, and the threaded hole and the through hole are respectively fitted with the threaded rod 407 and the limiting rod 406. The threaded hole and the through hole inside the sliding table 101 are respectively fitted with the threaded rod 407 and the limiting rod 406, so that when the threaded rod 407 rotates, the sliding table 101 can stably move horizontally along the threaded rod 407 and the limiting rod 406, thereby adjusting the position of the blade 107 to facilitate the contact between the blade 107 and the paper to complete the cutting process.

[0024] Further, a drive shaft 110 is installed inside the first installation chamber 109 through a bearing, and a drive motor 108 is fixedly installed at one end of the drive shaft 110. The drive shaft 110 can be driven to rotate by the drive motor 108, and then drive the blade 107 to roll at a constant speed. The drive motor 108 is of the YE3 - 50KW type. After the drive motor 108 is powered on, it can rotate to drive the drive shaft 110 to rotate.

[0025] Further, a second tension pulley 106 is installed inside one side of the second installation chamber 105 through a bearing. A connection box 103 is fixedly installed on the back of the sliding table 101, and the connection box 103 is fixedly connected to the first installation chamber 109 and the second installation chamber 105. A heat dissipation fan 102 is fixedly installed on one side inside the connection box 103, and two first tension pulleys 104 are installed inside the connection box 103 through bearings. The blade 107 is sleeved on the outer sides of the first tension pulley 104, the second tension pulley 106 and the drive shaft 110. The blade 107 is an annular flexible metal knife, and the side of the blade 107 facing the installation box 3 is the cutting edge. The second tension pulley 106 can cooperate with the first tension pulley 104 and the drive shaft 110, so that the blade 107 is annularly installed inside the cutting assembly 1, and the drive shaft 110 drives the blade 107 to roll at a constant speed. The heat dissipation fan 102 can drive the air flow inside the connection box 103, thereby facilitating the heat dissipation of the blade 107 and preventing the temperature of the blade 107 from rising during continuous operation, which affects the cutting effect of the blade 107 on the paper.

[0026] Further, a support frame 402 is fixedly installed at the bottom of the processing table 4. An installation plate 404 is fixedly installed on the front of the top of the processing table 4, and an operation table 403 is fixedly installed on the front of the installation plate 404. The support frame 402 can support the processing table 4 to ensure the overall stability of the device. The installation plate 404 can provide an installation position for the operation table 403 and guide the paper between the installation plate 404 and the back plate 401, so that the paper moves stably on the top of the processing table 4, facilitating the batch cutting process of the paper.

[0027] Furthermore, a vacuum pump 303 is fixedly installed on one side inside the installation box 3, and two motors 304 are fixedly installed at the top inside the installation box 3. The output shaft of the motor 304 extends to the top of the processing table 4 and is fixedly installed with a rotating shaft 305, and a fixed disk 306 is fixedly installed at the top end of the rotating shaft 305. One side above the processing table 4 is installed with a first guiding roller 301, and a second guiding roller 302 is installed on the front of the first guiding roller 301. Adsorption grooves 3021 are formed on the sides of the first guiding roller 301 and the second guiding roller 302. The inner walls of the first guiding roller 301 and the second guiding roller 302 are fixedly connected to the fixed disk 306. The vacuum pump 303 is of the 10D1125 - 101 - 1052 type. After the vacuum pump 303 is powered on, it can suck the air inside the installation box 3, creating a negative pressure environment inside the installation box 3. And by means of the diversion holes 409, the air inside the first guiding roller 301 and the second guiding roller 302 is continuously sucked into the installation box 3, making the inside of the first guiding roller 301 and the second guiding roller 302 also create a negative pressure environment, so as to facilitate guiding and sorting the paper by the first guiding roller 301 and the second guiding roller 302. The motor 304 is of the YE3 - 50KW type. After the motor 304 is powered on, it can rotate, and then drive the rotating shaft 305 and the components on its top to rotate at a uniform speed. The fixed disk 306 can fixedly connect the rotating shaft 305 with the first guiding roller 301 and the second guiding roller 302, so that the first guiding roller 301 and the second guiding roller 302 rotate at a uniform speed, and the rotating directions of the first guiding roller 301 and the second guiding roller 302 are opposite, and the rotation speeds of the first guiding roller 301 and the second guiding roller 302 are the same. The adsorption grooves 3021 on one side of the first guiding roller 301 and the second guiding roller 302 all face the direction of the mounting plate 404 in the initial state.

[0028] Furthermore, two groups of diversion holes 409 are formed on one side inside the processing table 4, and the diversion holes 409 are distributed in an annular array outside the rotating shaft 305, and the diversion holes 409 are all distributed inside the first guiding roller 301 and the second guiding roller 302. The diversion holes 409 can connect the inside of the first guiding roller 301, the second guiding roller 302 with the inside of the installation box 3, so as to facilitate the continuous air extraction by the vacuum pump 303, creating a negative pressure environment inside the first guiding roller 301, the second guiding roller 302 and the installation box 3, so as to facilitate adsorbing and guiding the paper by the adsorption grooves 3021 on the sides of the first guiding roller 301 and the second guiding roller 302.

[0029] Working principle: After the device is assembled and checked to be correct, adjust the adsorption grooves 3021 on the sides of the first guide roller 301 and the second guide roller 302 to face the mounting plate 404. Control the device to start working through the operation console 403. The driving motor 108 is energized to rotate, driving the driving shaft 110 to rotate, so that the blade 107 rolls at a constant speed. At the same time, the cooling fan 102 starts to rotate to perform air-cooling on the blade 107 entering the inside of the connection box 103. The motor 304 is energized to rotate, driving the first guide roller 301 and the second guide roller 302 to rotate respectively. The vacuum pump 303 sucks the air inside the first guide roller 301, the second guide roller 302 and the mounting box 3, creating a negative pressure environment inside the first guide roller 301, the second guide roller 302 and the mounting box 3; When starting the cutting work, insert one end of the paper roll vertically into the gap between the first guide roller 301 and the second guide roller 302. Rely on the first guide roller 301 and the second guide roller 302 to drive the paper to move towards the blade 107 at a constant speed. At the same time, the adsorption grooves 3021 on the sides of the first guide roller 301 and the second guide roller 302 come into contact with the paper in turn, stacking the paper at the position between the first guide roller 301, the second guide roller 302 and the blade 107. After the screw motor 408 is energized to rotate, drive the threaded rod 407 to rotate, so that the cutting assembly 1 slides towards the paper at a constant speed along the threaded rod 407 and the limiting rod 406. Apply pressure to the paper by contacting the paper with the limiting piece 203. At the same time, the first limiting roller 201 and the second limiting roller 204 guide the blade 107, so that the blade 107 contacts the paper vertically to start cutting. The cut paper is discharged from one side of the processing table 4 to complete the cutting process of the paper; During the process of the blade 107 rolling at a constant speed, control the slider 501 to longitudinally move on one side of the electromagnetic rail 502 through the main control box 506 to adjust the angles of the first grinding plate 504 and the second grinding plate 508, so that the first grinding plate 504 and the second grinding plate 508 contact the front and back sides of the blade 107 respectively, grinding the front and back sides of the blade edge of the blade 107, so that the blade 107 contacts the paper after grinding to complete cutting. After cutting, grind again to realize the automatic maintenance of the blade 107 during the working process of the device.
