Description

Technical Field

[0001] This application relates to the field of slitting machines, and more particularly to an anti-clogging device for a slitting machine. Background Technology

[0002] A slitting machine is a processing equipment that cuts wide materials (such as paper, film, metal foil, fabric, etc.) into strips according to a preset width. It is widely used in industries such as packaging, printing, electronics, and new energy. The raw materials are stably fed through an unwinding device, and the material is precisely divided into multiple narrow strips by a cutting system with multiple sets of circular or straight blades to meet the diverse material size requirements of different processes.

[0003] Traditional slitting equipment has difficulty in dynamically adjusting the blade spacing and cutting angle according to the ductility, thickness and surface characteristics of different materials. In addition, the blades lack a self-cleaning mechanism. When cutting highly viscous or fibrous materials, residual adhesive and debris will accumulate on the cutting edge, requiring the equipment to be stopped frequently for manual cleaning. The fine debris and dust generated during cutting accumulate in the blade working area, further increasing the risk of blade jamming. Utility Model Content

[0004] In order to improve the problems of material sticking to the blade and the accumulation of debris and dust that cause blade blockage, this application provides a blade anti-blocking device for a slitting machine.

[0005] The anti-clogging device for a slitting machine provided in this application adopts the following technical solution: A slitting machine anti-clogging device includes a fixed base and an adjustment mechanism fixedly mounted on the upper middle part of the fixed base. A steering mechanism is symmetrically rotatably mounted on the lower end of the adjustment mechanism. A cutting mechanism for cutting material is fixedly mounted on the bottom end of the steering mechanism. Adsorption mechanisms for absorbing dust and debris are symmetrically fixed on opposite sides of the two cutting mechanisms. A motor providing power to the steering mechanism is symmetrically slidably mounted on the upper middle part of the fixed base. The adjustment mechanism includes an adjustment block and a bidirectional lead screw rotatably passing through the middle of the adjustment block. One end of the bidirectional lead screw located inside the adjustment block is symmetrically threaded and slides along the inner wall of the adjustment block. The second slider has a knob fixed at one end of the bidirectional lead screw outside the adjusting block; the steering mechanism includes a steering block rotatably disposed at the lower end of the second slider and a steering rod fixedly inserted at the upper end of the steering block, wherein a locking block is engaged above the end of the steering rod away from the steering block, and a sleeve block fixed to one side of the second slider is slidably sleeved on the top of the locking block; the cutting mechanism includes a housing and a cutting blade rotatably disposed inside the housing, a sponge is fixed inside the housing, and a transmission sleeve rod is rotatably disposed through one side of the lower end of the housing and both sides of the lower end of the sponge, and the cutting blade is fixedly sleeved on the part of the transmission sleeve rod inside the sponge.

[0006] By adopting the above technical solution, the bidirectional lead screw drives the slider two to move the steering mechanism horizontally, thereby achieving precise adjustment of the cutting mechanism spacing. The meshing design of the steering rod and the locking block ensures that the cutting mechanism maintains a stable cutting angle when the steering block rotates. The transmission sleeve drives the cutting blade to rotate to complete the material cutting. The sponge inside the outer shell absorbs the dust generated during cutting and cleans the cutting blade. The adsorption mechanism forms a negative pressure through the reciprocating motion of the piston rod, which sucks the dust into the dust collection bag through the adsorption box and the check valve two, preventing the blade from clogging and improving the working environment.

[0007] Preferably, the two ends of the steering rod located on both sides of the steering block pass through the lower end of the second slider, and the end of the steering rod away from the steering block is provided with a toothed groove.

[0008] By adopting the above technical solution, the steering rod passes through the lower end of the slider and engages with the locking block through the tooth groove at one end, thereby locking the angle when the steering block rotates and ensuring that the cutting mechanism maintains a stable cutting direction after adjusting the spacing.

[0009] Preferably, the bottom end of the locking block is provided with a protrusion that engages with the tooth groove, the bottom end of the sleeve block is provided with a rectangular hole, the top end of the locking block slides in the rectangular hole, and a spring is fixed to the locking block, with the two ends of the spring being fixed to the inner top surface of the rectangular hole and the top end of the locking block, respectively.

[0010] By adopting the above technical solution, the locking block achieves angle locking by meshing the bottom protrusion with the steering rod tooth groove, and the top slides in the rectangular hole of the sleeve block and compresses the spring, using the spring force to maintain the meshing state and prevent the steering rod from loosening during cutting. At the same time, the locking can be released by compressing the spring to adjust the cutting angle.

[0011] Preferably, a transmission rod is slidably disposed inside the transmission sleeve rod, the end of the transmission rod away from the transmission sleeve rod is fixed to the output end of the motor, and a cam is fixedly sleeved on the end of the transmission sleeve rod located outside the housing.

[0012] By adopting the above technical solution, the transmission rod transmits the motor power to the transmission sleeve rod and drives the transmission sleeve rod to rotate. At the same time, the transmission sleeve rod slides with the transmission rod to adapt to the position adjustment of the cutting mechanism. The cam at one end of the transmission sleeve rod rotates with the transmission sleeve rod, periodically driving the adsorption mechanism to achieve dust adsorption.

[0013] Preferably, the adsorption mechanism includes an adsorption cylinder fixed to one side of the outer shell and a piston rod that slides through the adsorption cylinder. A fixing block fixed to one side of the outer shell is fixed to one side of the piston rod. A second spring is sleeved on one end of the piston rod outside the adsorption cylinder. The two ends of the second spring are respectively fixed to the middle part of the adsorption cylinder near the piston rod and the surface of the piston rod.

[0014] By adopting the above technical solution, the adsorption mechanism compresses the piston rod by squeezing the cam, and uses the spring's restoring force to drive the piston rod to slide back and forth in the adsorption cylinder, forming a periodic negative pressure that draws the dust generated during cutting into the dust collection bag through the adsorption box, thus achieving the functions of anti-clogging and dust removal.

[0015] Preferably, a connecting pipe is fixedly provided at the end of the adsorption cylinder away from the piston rod, a three-way pipe is fixedly provided at the end of the connecting pipe away from the adsorption cylinder, a check valve is fixedly provided at the end of the three-way pipe away from the connecting pipe, the end of the three-way pipe away from the connecting pipe is fixed to the air inlet of the check valve, and the air outlet of the check valve is fixedly connected to one port of the dust discharge pipe.

[0016] By adopting the above technical solution, the adsorption cylinder is connected to the three-way pipe through the connecting pipe. Utilizing the one-way conduction characteristic of the check valve, it is ensured that when the piston rod draws air, the dust enters the dust discharge pipe from the adsorption cylinder through the three-way pipe and the check valve, while the gas in the dust discharge pipe will not flow back into the adsorption cylinder, thus ensuring the directional discharge of dust.

[0017] Preferably, a conveying pipe is fixedly provided at the top end of the three-way pipe, and a check valve two is fixedly provided at the end of the conveying pipe away from the three-way pipe. The end of the conveying pipe away from the three-way pipe is fixedly connected to the air outlet end of the check valve two. An adsorption box fixed to one side of the outer shell is provided at the air inlet end of the check valve two. The top middle part of the adsorption box is fixedly connected to the air inlet end of the check valve two. Several oblique holes are evenly opened at the bottom end of the adsorption box.

[0018] By adopting the above technical solution, the three-way pipe is connected to the adsorption box through the conveying pipe and the second check valve. The second check valve ensures that during adsorption, dust can only be drawn in from the inclined hole at the bottom of the adsorption box and enter the conveying pipe in one direction through the second check valve, preventing gas backflow and realizing the directional collection and backflow prevention protection of dust in the cutting area.

[0019] Preferably, a slider fixed to the motor is symmetrically slidably arranged at the upper middle part of the fixed base, and a connecting block fixed on one side and the two sides of the adjusting block is symmetrically fixed at the top middle part of the fixed base. The end of the bidirectional screw located outside the adjusting block moves through one of its connecting blocks and the upper part of one side of the fixed base. A dust discharge pipe is provided at the lower part of one side of the fixed base, and a dust collection bag is fixedly provided at the top end of the dust discharge pipe.

[0020] By adopting the above technical solution, the fixed seat achieves horizontal sliding through the slider-support motor to adapt to the adjustment of the cutting spacing, the connecting block and the fixed adjusting block ensure the stable rotation of the bidirectional lead screw, and the dust discharge pipe and the dust collection bag cooperate to discharge the dust collected by the adsorption mechanism in a directional manner and store it centrally.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. The motor drives the transmission rod to rotate, which in turn drives the transmission sleeve and the cutting blade to rotate. At the same time, the cutting blade rotates inside a sponge soaked in cleaning solution, allowing the cleaning solution to clean the cutting surface and initially adsorb dust and debris. Simultaneously, the cam periodically pushes the piston rod to reciprocate, causing alternating negative and positive pressures inside the adsorption cylinder. Cutting dust is drawn in through the oblique holes of the adsorption box, and then flows through the conveying pipe and the three-way pipe into the dust discharge pipe and is collected by the dust collection bag. This achieves self-cleaning and continuous adsorption during the cutting process, avoiding the accumulation of residual glue and debris, reducing the risk of blade jamming, and extending the continuous operation time of the equipment.

[0022] 2. By rotating the knob, the bidirectional lead screw is rotated, causing the bidirectional thread to drive two sliders to slide in opposite directions along the adjusting block. This drives the steering mechanism to adjust the horizontal spacing of the cutting mechanism to match the material width. Simultaneously, by lifting the locking block upwards to release the rotation restriction of the steering rod, the steering rod is rotated to drive the steering block to rotate, adjusting the deflection angle of the cutting mechanism to match the material thickness and surface characteristics. This allows the equipment to dynamically adjust the cutting parameters according to the ductility, thickness, and other characteristics of different materials, avoiding cutting defects caused by fixed parameters and improving cutting accuracy and applicability.

[0025] The following is in conjunction with the appendix Figure 1 - Figure 10 This application will be described in further detail.

[0026] This application discloses an anti-clogging device for a slitting machine.

[0027] Reference Figure 1 A slitting machine anti-clogging device includes a fixed base 1 and an adjusting mechanism 2 fixedly mounted on the upper middle part of the fixed base 1. A steering mechanism 3 is symmetrically rotatably mounted on the lower end of the adjusting mechanism 2. A cutting mechanism 4 is fixedly mounted on the bottom end of the steering mechanism 3. Adsorption mechanisms 5 are symmetrically fixed on opposite sides of the two cutting mechanisms 4. The adsorption mechanisms 5 are used to adsorb dust and debris generated by the cutting mechanism 4 when cutting materials. Slide grooves 10 are opened on both sides of the upper middle part of the fixed base 1. A slider 8 is slidably mounted inside the slide groove 10. The shape of the slider 8 is adapted to the shape of the slide groove 10. The slide groove 10 provides guidance and a sliding track for the slider 8. A symmetrically mounted device is located at the top middle part of the fixed base 1. The connecting block 11 has a circular hole 12 in the middle and on the upper side of the fixed base 1. The fixed base 1 has a motor 9 symmetrically slidably mounted on the upper middle part. The motor 9 provides driving power for the steering mechanism 3. The lower side of the fixed base 1 has a dust discharge pipe 6. The top of the dust discharge pipe 6 is fixedly connected to a dust collection bag 7 (the dust collection bag 7 has a capacity of 10L, which is sufficient for long-term operation and does not need to be replaced frequently). The dust collection bag 7 is made of flexible plastic. Its top opening is fixedly connected to the bottom outer wall of the dust discharge pipe 6 by a clamp. The dust discharge pipe 6 is a Y-shaped pipe used to transfer the dust adsorbed by the adsorption mechanism 5 to the inside of the dust discharge pipe 6 for collection.

[0028] Before use, the device needs to be installed on the cutting section of the slitting machine. The adjusting mechanism 2 is fixedly installed on the upper middle part of the fixed base 1. The steering mechanism 3 is symmetrically installed on the lower part of the adjusting mechanism 2. The cutting mechanism 4 is fixed to the bottom of the steering mechanism 3 respectively. The adsorption mechanism 5 is symmetrically installed on the opposite side of the two cutting mechanisms 4 to complete the assembly of the cutting and adsorption components. Then, the slider 8 is slidably embedded into the grooves 10 opened on both sides of the upper middle part of the fixed base 1. The grooves 10 provide guidance and sliding track for the slider 8. The connecting block 11 is symmetrically fixed at the top middle part of the fixed base 1, so that one end of the bidirectional screw 202 rotates through the middle of one of the connecting blocks 11 and the upper side of one side of the fixed base 1. The two motors 9 are fixed on the opposite side of the two sliders 8. Dust collection bags 7 are placed on the ground on both sides of the equipment. The adsorption mechanism 5 at the top of the dust collection bag 7 is connected through the dust discharge pipe 6.

[0029] In use, the bidirectional lead screw 202 drives the slider 203 to slide in opposite directions inside the adjusting block 201, thereby adjusting the distance between the two cutting mechanisms 4 to adapt to the material width. The turning rod 302 adjusts the rotation of the cutting mechanism 4 around the lower end of the slider 203, thereby adjusting the deflection angle of the cutting mechanism 4 to adapt to materials of different thicknesses. The motor 9 drives the cutting mechanism 4 to cut. During the cutting process, the adsorption mechanism 5 moves with the cutting mechanism 4 and adsorbs the generated dust and debris. The debris is transferred to the dust collection bag 7 through the dust discharge pipe 6 for collection, thus realizing the synchronous operation of cutting position adjustment, material cutting and dust treatment.

[0030] The adjusting mechanism 2 includes an adjusting block 201 and a bidirectional lead screw 202 rotatably passing through the middle of the adjusting block 201. Both ends of the adjusting block 201 are fixed to opposite sides of two connecting blocks 11. The shape of the adjusting block 201 (e.g., ...) Figure 4 As shown), a circular hole 205 is provided on one side of the adjusting block 201. One end of the bidirectional lead screw 202 rotates through the circular hole 205. The surface of the end of the bidirectional lead screw 202 inside the adjusting block 201 has bidirectional threads. A slider 203 is symmetrically threaded onto the end of the bidirectional lead screw 202 inside the adjusting block 201. The shape of the upper end of the slider 203 is adapted to the shape of the inner wall of the adjusting block 201, so that the slider 203 slides on the inner wall of the adjusting block 201. The shape of the slider 203 (as shown) Figure 6As shown), the upper end of slider 203 has a threaded hole 207, and slider 203 is threaded onto the bidirectional lead screw 202 through the threaded hole 207. The lower end of slider 203 has a groove, and the inner wall of the groove of slider 203 has circular holes 206 on both sides. A knob 204 is fixed at one end of the bidirectional lead screw 202 outside the adjusting block 201. (A limiting block (such as a ratchet) is provided on one side of the knob 204. The limiting block is fixed to one side of the fixed seat 1 near the knob 204. The knob 204 and the limiting block are pressed together so that the vibration generated by the motor will not cause the bidirectional lead screw 202 to rotate. Only a large external force (such as manpower through a tool) can make the bidirectional lead screw 202 rotate.) Rotating the knob 204 drives the bidirectional lead screw 202 to rotate. The end of the bidirectional lead screw 202 outside the adjusting block 201 passes through the circular hole 12 opened on the connecting block 11 and the fixed seat 1. The knob 204 is located outside the fixed seat 1.

[0031] Rotating the knob 204 drives the bidirectional lead screw 202 to rotate, causing the bidirectional threads on the surface of the bidirectional lead screw 202 to drive the two sliders 203 to slide in opposite directions along the inner wall of the adjusting block 201. When the sliders 203 slide, they drive the steering mechanism 3 connected in the lower groove to move synchronously, thereby adjusting the horizontal position of the cutting mechanism 4 fixed at the bottom of the steering mechanism 3, so as to adjust the distance between the two cutting mechanisms 4 to adapt to cutting materials of different widths.

[0032] The steering mechanism 3 includes a steering block 301 rotatably mounted at the lower end of the slider 203 and a steering rod 302 fixedly inserted at the upper end of the steering block 301. The shape of the steering block 301 is as follows (e.g., Figure 6 As shown), a circular hole 308 is provided at the upper end of the steering block 301. The diameter of the circular hole 308 is the same as the diameter of the circular hole 206. The width of the steering block 301 is the same as the width of the groove at the lower end of the slider 203. The two sides of the steering block 301 are in contact with the inner wall of the groove at the lower end of the slider 203 twice. The upper end of the steering block 301 is located in the groove of the slider 203. The center lines of the circular hole 308 and the circular hole 206 are on the same horizontal line. One end of the steering rod 302 is movably inserted through the circular hole 206. The part of the steering rod 302 located inside the groove at the lower end of the slider 203 is fixedly inserted through the circular hole 308.

[0033] By lifting the locking block 303 upwards, the locking block 303 moves towards the sleeve block 304, causing the bottom protrusion of the locking block 303 to separate from the tooth groove 307, thus releasing the rotation restriction on the steering rod 302. At this time, the spring 305 is in a compressed state. Rotating the steering rod 302 drives the steering block 301 to rotate in the groove at the lower end of the slider 203 to a suitable position. The locking block 303 is then released, and the spring 305 rebounds, pushing the locking block 303 back to its original position, causing the bottom protrusion of the locking block 303 to re-engage in the tooth groove 307, automatically locking the steering rod 302 and keeping it stable. At the same time, the rotation of the steering block 301 causes the cutting mechanism 4, which is fixed at the bottom of the steering block 301, to adjust its flipping angle, thereby adjusting the angle of the cutting mechanism 4 to adapt to cutting materials with different ductility, thickness, and surface characteristics.

[0034] The steering lever 302 has a toothed groove 307 at the end away from the steering block 301. A sleeve block 304 is fixed to the middle of one side of the slider 203. The side of the sleeve block 304 near the slider 203 is fixed to the middle of one side of the slider 203. A rectangular hole 306 is opened inside the sleeve block 304. A locking block 303 is slidably arranged inside the rectangular hole 306. The upper end of the locking block 303 is a T-shaped block, the lower end is an arc-shaped block, and the middle of the side is a long handle. The shape of the T-shaped block at the upper end of the locking block 303 matches the internal shape of the rectangular hole 306. The top of the locking block 303... A spring 305 is fixedly installed (the formula for calculating the elastic force of spring 305 is F=kx, where F represents the elastic force of spring 305, k represents the constant of spring 305, and x represents the compression of spring 305). The two ends of spring 305 are fixed to the inner top surface of rectangular hole 306 and the top of locking block 303, respectively. Multiple protrusions are fixed on the inner bottom surface of the arc-shaped block at the lower end of locking block 303. The shape of the protrusions matches the shape of the tooth groove 307. The bottom protrusion of locking block 303 is engaged in tooth groove 307 under normal conditions, restricting the rotation of steering rod 302.

[0035] When the horizontal position or deflection angle of the cutting mechanism 4 is adjusted, the outer shell 401 fixed on the steering block 301 drives the transmission sleeve 404 to move, so that the irregular groove 411 inside the transmission sleeve 404 slides relative to the transmission rod 405 fixed on the output shaft of the motor 9; at the same time, it drives the slider 8 fixed at the bottom of the motor 9 to slide along the slide groove 10 at the upper end of the fixed seat 1, so that the motor 9 moves synchronously with the cutting mechanism 4, further maintaining the effective meshing length between the transmission rod 405 and the irregular groove 411.

[0036] The cutting mechanism 4 includes a housing 401 and a cutting blade 402 rotatably mounted inside the housing 401. A circular hole 407 is provided on one side of the lower end of the housing 401. A sponge 403 filled with cleaning solution is fixedly installed inside the housing 401. The sponge 403 surrounds the cutting blade 402. The volume of the sponge 403 is 50 cm³, which can meet most cutting needs. The sponge 403 is replaced regularly to ensure the cleaning effect. The cleaning solution is a water-based rust-preventive coolant (which facilitates cleaning the blade and prevents rusting) or an ethanol solution. It can clean and cool the cutting blade 402 and the cutting surface of the material, and also wet the dust and debris so that they can easily agglomerate and settle. A circular hole 410 is provided in the middle of the cutting blade 402. A circular hole 408 is provided on one side of the lower end of the sponge 403. The center point of the circular hole 408 coincides with that of the circular hole 407, and the circular holes 407 and 408 are located on the same horizontal line.

[0037] A transmission sleeve 404 is rotatably installed on one side of the lower end of the outer shell 401 and on both sides of the lower end of the sponge 403. The transmission sleeve 404 passes through circular holes six 408 and five 407. The part of the transmission sleeve 404 located inside the sponge 403 is fixedly installed in the circular hole eight 410 of the cutting blade 402. The shape of the cutting blade 402 is as follows (e.g., ...). Figure 8 As shown), the cutting blade 402 is used to cut materials. The transmission sleeve 404 has an irregular groove 411 inside. The transmission rod 405 is slidably arranged inside the irregular groove 411. The shape of the transmission rod 405 is adapted to the shape of the irregular groove 411. The end of the transmission rod 405 away from the transmission sleeve 404 is fixed to the output end of the motor 9. The end of the transmission sleeve 404 located outside the housing 401 is fixedly fitted with a cam 406. The middle part of the cam 406 has a circular hole 409. The transmission sleeve 404 passes through the circular hole 409.

[0038] By turning on the motor 9 to drive the transmission rod 405 to rotate, the transmission rod 405 drives the transmission sleeve 404 to rotate synchronously through the irregular groove 411. This causes the cutting blade 402 fixed on the surface of the transmission sleeve 404 to rotate around the inside of the outer shell 401, cutting the material. Since part of the cutting blade 402 is inside the sponge 403 filled with cleaning solution, the cleaning solution simultaneously wets the cutting surface and absorbs the dust and debris generated during cutting, achieving synchronous operation of cutting and cleaning. At the same time, the rotation of the transmission sleeve 404 drives the cam 406 fixed at its end to rotate synchronously. After cutting, a 5-minute cleaning cycle can be performed to ensure that the blade remains clean and to prevent dust accumulation.

[0039] The adsorption mechanism 5 includes an adsorption cylinder 501 fixed to one side of the outer casing 401 and a piston rod 502 that slides through the inside of the adsorption cylinder 501. The shape of the piston rod 502 is as follows: Figure 9As shown in the diagram, a piston is fixedly mounted on one end of the piston rod 502 inside the adsorption cylinder 501. The piston is made of wear-resistant rubber. The diameter of the end of the piston rod 502 inside the adsorption cylinder 501 is the same as the inner wall diameter of the adsorption cylinder 501. A fixing block 510 is fixed on one side of the piston rod 502. The side of the fixing block 510 near the outer shell 401 is fixed to the side of the outer shell 401 facing the adsorption cylinder 501. The fixing block 510 guides the piston rod 502, restricting the piston rod 502 to only move along its axis. The line makes a linear reciprocating motion. The middle part of the piston rod 502 moves through one side of the adsorption cylinder 501. A spring 503 is sleeved on one end of the piston rod 502 outside the adsorption cylinder 501 (the formula for calculating the elastic force of spring 503 is F=kx, where F represents the elastic force of spring 503, k represents the constant of spring 503, and x represents the compression of spring 503). The two ends of the spring 503 are fixed to the middle part of the side of the adsorption cylinder 501 near the piston rod 502 and the surface of the piston rod 502, respectively.

[0040] A connecting pipe 505 is fixedly installed at the end of the adsorption cylinder 501 away from the piston rod 502. A three-way pipe 507 is fixedly installed at the end of the connecting pipe 505 away from the adsorption cylinder 501. The three-way pipe 507 is a pipe with three openings. A check valve 506 is fixedly installed at the end of the three-way pipe 507 away from the connecting pipe 505. The end of the three-way pipe 507 away from the connecting pipe 505 is fixed to the air inlet of the check valve 506. The air outlet of the check valve 506 is fixedly connected to one port of the dust discharge pipe 6. A conveying pipe is fixedly installed at the top of the three-way pipe 507. 508, a check valve 2 509 is fixedly installed at the end of the delivery pipe 508 away from the three-way pipe 507. The end of the delivery pipe 508 away from the three-way pipe 507 is fixedly connected to the outlet end of the check valve 2 509. An adsorption box 504 is fixedly installed at the inlet end of the check valve 2 509. The middle part of the adsorption box 504 is fixedly connected to the inlet end of the check valve 2 509. The end of the adsorption box 504 near the outer shell 401 is fixed to one side of the outer shell 401. Several oblique holes 511 are evenly opened at the bottom end of the adsorption box 504. The check valve 2 509 is fixedly installed in the middle of the top end of the adsorption box 504.

[0041] The cam 406 rotates with the transmission sleeve 404, and its protruding part periodically contacts and pushes the piston rod 502 at one end outside the adsorption cylinder 501, causing the piston rod 502 to reciprocate (the reciprocating cycle of the piston rod 502 is 3 seconds, and the dust is sucked in and discharged in each cycle to ensure continuous cleaning). This causes the piston rod 502 to move periodically inside the adsorption cylinder 501, while simultaneously compressing the second spring 503 and returning it to its original position, thereby creating an alternating negative and positive pressure environment inside the adsorption cylinder 501. When the piston rod 502 is protruded... When the roller 406 is squeezed, the positive pressure in the adsorption cylinder 501 pushes the gas through the connecting pipe 505, through the three-way pipe 507, and the first check valve 506 to discharge it into the dust discharge pipe 6. When the piston rod 502 is reset, the negative pressure in the adsorption cylinder 501 draws in the dust and debris generated during cutting through the conveying pipe 508 and the second check valve 509 from the inclined hole 511 of the adsorption box 504. The dust enters the conveying pipe 508 through the adsorption box 504 and flows into the dust discharge pipe 6 through the three-way pipe 507 and is collected by the dust collection bag 7, thus realizing the continuous adsorption and transmission of cutting dust.

[0042] The implementation principle of the anti-blocking device for a slitting machine according to an embodiment of this application is as follows: During use, rotating the knob 204 drives the bidirectional lead screw 202 to rotate, causing the bidirectional threaded drive slider 203 to slide in opposite directions along the adjusting block 201, thereby driving the steering mechanism 3 to adjust the horizontal spacing of the cutting mechanism 4 to match the material width; after lifting the locking block 303 to release the locking of the steering rod 302, it rotates to a suitable position, adjusting the deflection angle of the cutting mechanism 4 to match the material thickness; after releasing the locking block 303, the spring 305 resets, pushing the bottom protrusion of the locking block 303 back into the toothed groove 307 on the steering rod 302; the motor 9 is then turned on to drive the transmission rod 405 to rotate. This drives the transmission sleeve 404 and the cutting blade 402 to rotate and cut the material. At the same time, the cutting blade 402 rotates in the sponge 403, which is filled with cleaning solution, to clean the cut surface and initially absorb dust. When the transmission sleeve 404 rotates, it drives the cam 406 to periodically push the piston rod 502 to reciprocate, so that negative pressure and positive pressure are alternately generated in the adsorption cylinder 501. When the pressure is negative, the cutting dust is sucked in through the inclined hole 511 of the adsorption box 504. The dust enters the three-way pipe 507 through the adsorption box 504, the second check valve 509, and the conveying pipe 508. When the pressure is positive, the gas is discharged into the dust discharge pipe 6 through the three-way pipe 507 and the first check valve 506. Finally, the dust is collected by the dust collection bag 7.
