Description
Technical Field
[0001] This utility model relates to the field of slitting machine technology, specifically a precision slitting machine. Background Technology
[0002] A slitting machine is a machine used to cut wide strips of material into multiple narrower strips. This equipment is widely used in various industrial sectors, including but not limited to packaging, printing, papermaking, plastics, textiles, and metal processing. The main function of a slitting machine is to cut continuous large rolls of material into smaller rolls as needed to meet the requirements of subsequent processing or final use.
[0003] Currently, when adjusting the spacing of the slitting blades on a slitting machine, each blade needs to be manually unsecured, and the distance between each blade needs to be measured with a ruler before being moved and fixed again. This adjustment method not only easily leads to large errors in the distance between each blade, resulting in inaccurate slitting width, but also makes adjusting the position of multiple blades individually time-consuming and laborious, affecting the processing efficiency of the slitting machine. Utility Model Content

[0007] As a preferred embodiment of this utility model of a precision slitting machine, the slitting mechanism includes a base, a first side plate and a second side plate fixed to the top of the base, two support plates fixed to the surface of the second side plate, four guide rollers detachably connected between the first side plate and the second side plate, a slitting roller and a feeding roller rotatably connected to the surface of the first side plate, two drive motors fixed to the surface of the first side plate, the output shaft of the drive motors fixedly connected to one end of the slitting roller, the surfaces of both the first side plate and the second side plate fixedly connected to the surface of the first cylinder, and slots for movement of mounting plates opened on the surfaces of both the first side plate and the second side plate.
[0008] As a preferred embodiment of the present invention, the precision slitting machine includes a driven plate surface locking structure comprising a through groove formed on the driven plate surface, a partition plate fixed to the inner wall of the through groove, a fastening knob threaded through the surface of the partition plate, and a friction plate fixedly connected to one end of the fastening knob.
[0009] As a preferred embodiment of this utility model of a precision slitting machine, both the housing and the slitting blade have multiple assembly holes on their surfaces, and the slitting blade and the housing are detachably connected by bolts through the assembly holes.
[0010] As a preferred embodiment of the present invention, a precision slitting machine includes a limiting mechanism comprising three mounting shells. The mounting shells are fixed to the surface of a second side plate. A second cylinder is fixed to the surface of the mounting shell. One end of the second cylinder passes through the mounting shell and is fixed to a slider. A first baffle is hinged to the surface of the slider on the front side, and a second baffle is hinged to the surface of the slider on the rear side. Bearing rings are fixed to the surfaces of both the first baffle and the second baffle.
[0011] As a preferred embodiment of the present invention, a precision slitting machine is provided, wherein an L-shaped block is fixed on the surface of both the first baffle and the second baffle, a pin is slidably passed through the surface of the L-shaped block, and a pin hole is provided at the top of the slider for inserting the pin.
[0012] As a preferred embodiment of the present invention, a precision slitting machine includes a positioning mechanism comprising two blocking sleeves, the blocking sleeves being slidably connected to the surface of the feeding roller, a screw threaded through the surface of the blocking sleeve, and a clamping plate rotatably connected to the bottom of the screw.

The surface of the connecting block is fixedly connected to the surface of the clamping plate.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] This invention, through the design of the slitting mechanism, allows the first cylinder to adjust the height of the mounting plate, thereby changing the height of the slitting blade. When the control motor starts, it drives the bidirectional lead screw to rotate, enabling the two active plates to move towards or away from each other on the surfaces of the lead screw and slide bar. Furthermore, as the active plates move, they also move the outermost driven plate. When the outermost driven plate moves, the folding connecting rod extends, allowing multiple driven plates to be equidistantly separated. This achieves equidistant adjustment of the distance between multiple slitting blades, eliminating the need for operators to manually adjust the distance between them. The device allows for individual adjustment of the position of each slitting blade, thereby improving the adjustment efficiency of the slitting machine and enabling it to achieve better working efficiency. The equidistant adjustment effect of the device is more accurate than manual adjustment, preventing any slitting blade from being misaligned due to human error or forgetfulness. This results in better precision in the width of the cut material. After the slitting blade position is adjusted, a locking structure can be used to fix the slitting blade, further improving the accuracy of the slitting process. The through-hole design ensures that the bidirectional lead screw does not contact the driven plate, allowing the driven plate to move normally on the slide bar surface. Attached Figure Description

[0025] Please see Figures 1-8 A precision slitting machine includes a slitting mechanism 1, on the surface of which a slitting mechanism 2, a limiting mechanism 3, and a positioning mechanism 4 are mounted.
[0026] The slitting mechanism 2 includes a first cylinder 201, a mounting plate 202 fixed to the bottom of the first cylinder 201, a regulating motor 203 fixed to the surface of the mounting plate 202, an output shaft of the regulating motor 203 passing through the first cylinder 201 and fixed to a bidirectional lead screw 204, one end of the bidirectional lead screw 204 being rotatably connected to the inner wall of the mounting plate 202, two sliding rods 205 fixed to the inner wall of the mounting plate 202, and two drive plates 208 threadedly connected to the surface of the bidirectional lead screw 204, the drive plates 208 being slidably connected to the surfaces of the sliding rods 205. Multiple driven plates 206 are arranged between the two active plates 208. A folding connecting rod 207 is installed on the top of the driven plate 206. The surface of the active plate 208 is fixedly connected to the surface of the outermost driven plate 206. A sleeve 209 is fixed to the bottom of the driven plate 206. A slitting blade 210 is arranged inside the sleeve 209. A through hole 212 is opened on the surface of the driven plate 206. The diameter of the through hole 212 is larger than that of the bidirectional lead screw 204. The driven plate 206 is slidably connected to the surface of the slide rod 205. A locking structure is provided on the surface of the driven plate 206.
[0027] The height of the mounting plate 202 can be adjusted by the first cylinder 201, thereby changing the height of the slitting blade 210. When the control motor 203 is started, it drives the bidirectional lead screw 204 to rotate, allowing the two active plates 208 to move towards or away from each other on the surfaces of the bidirectional lead screw 204 and the slide bar 205. When the active plates 208 move, they also drive the outermost driven plate 206 to move. When the outermost driven plate 206 moves, the folding connecting rod 207 can extend, allowing the multiple driven plates 206 to be equidistantly separated. This achieves equidistant adjustment of the distance between the multiple slitting blades 210, eliminating the need for operator intervention. The position of each individual slitting blade 210 is then adjusted to improve the device's adjustment efficiency, enabling the slitting machine to achieve better working efficiency. Furthermore, the equidistant adjustment of the device is more accurate than manual adjustment, preventing any slitting blade 210 from being left unadjusted due to human error or forgetfulness. This results in better accuracy in the width of the material after slitting. After the slitting blade 210 is adjusted, it can be fixed using a locking structure to further improve the accuracy of slitting. The through-hole 212 design ensures that the bidirectional lead screw 204 does not contact the driven plate 206, allowing the driven plate 206 to move normally on the surface of the slide bar 205.
[0028] Furthermore, the slitting mechanism 1 includes a base 101, a first side plate 102 and a second side plate 103 fixed to the top of the base 101, two support plates 108 fixed to the surface of the second side plate 103, four guide rollers 104 detachably connected between the first side plate 102 and the second side plate 103, a slitting roller 106 and a feeding roller 107 rotatably connected to the surface of the first side plate 102, two slitting rollers 106, two drive motors 105 fixed to the surface of the first side plate 102, the output shaft of the drive motor 105 fixedly connected to one end of the slitting roller 106, the surfaces of the first side plate 102 and the second side plate 103 fixedly connected to the surface of the first cylinder 201, and slots that cooperate with the mounting plate 202 to move on the surfaces of the first side plate 102 and the second side plate 103.
[0029] The material can be placed on the surface of the feeding roller 107, and the material can pass through the four guide rollers 104 to obtain a guiding effect. After the material is cut by the slitting knife 210, the material can be wound onto the surface of two different slitting rollers 106. When the drive motor 105 is working, it can drive the slitting rollers 106 to rotate, so that the material can automatically pass through the slitting knife 210. The slot design ensures that the mounting plate 202 can move up and down in the slot.
[0030] Furthermore, the surface locking structure of the driven plate 206 includes a through groove 211 opened on the surface of the driven plate 206, a partition 213 fixed on the inner wall of the through groove 211, a fastening knob 214 threaded through the surface of the partition 213, and a friction plate 215 fixedly connected to one end of the fastening knob 214.
[0031] After the positions of multiple driven plates 206 are adjusted by rotating the bidirectional lead screw 204, the friction plate 215 can be pressed against the slide bar 205 by rotating the fastening knob 214. This increases the friction force and fixes the driven plates 206 on the surface of the slide bar 205, preventing the driven plates 206 from wobbling slightly due to vibrations during the cutting process, thereby further improving the cutting accuracy.
[0032] Furthermore, both the housing 209 and the slitting blade 210 have multiple assembly holes 216 on their surfaces, and the slitting blade 210 and the housing 209 are detachably connected by bolts through the assembly holes 216.
[0033] This design allows the slitting blade 210 to be removed from the housing 209, which further increases the distance between each slitting blade 210, meeting the need for wider material slitting, and also allows the worn slitting blade 210 to be removed and replaced.
[0034] Furthermore, the limiting mechanism 3 includes three mounting shells 301. The mounting shells 301 are fixed to the surface of the second side plate 103. A second cylinder 302 is fixed to the surface of the mounting shell 301. One end of the second cylinder 302 passes through the mounting shell 301 and is fixed to a slider 303. A first baffle 304 is hinged to the surface of the front slider 303, and a second baffle 305 is hinged to the surface of the rear slider 303. Bearing rings 306 are fixed to the surfaces of both the first baffle 304 and the second baffle 305.
[0035] When the first baffle 304 and the second baffle 305 are located on top of the support plate 108, the support plate 108 can support the first baffle 304 and the second baffle 305. At this time, the right end surface of the slitting roller 106 can be located inside the bearing ring 306 on the surface of the first baffle 304, and the right end surface of the feeding roller 107 can also be located inside the bearing ring 306 on the surface of the second baffle 305. This makes the support effect of the slitting roller 106 and the feeding roller 107 better. When installing or removing material from the surface of the slitting roller 106 and the loading roller 107, the second cylinder 302 is activated, causing the slider 303 to move the first baffle 304 to the right, thereby causing the bearing ring 306 to detach from the surface of the slitting roller 106 and the loading roller 107. Then, the first baffle 304 and the second baffle 305 are manually rotated to ensure that the right side of the slitting roller 106 and the loading roller 107 is unobstructed, thus allowing normal material installation operations to be performed on the surface of the slitting roller 106 and the loading roller 107.
[0036] Furthermore, L-shaped blocks 307 are fixed on the surfaces of the first baffle 304 and the second baffle 305, and pins 308 slide through the surface of the L-shaped blocks 307. A pin hole is opened at the top of the slider 303 to accommodate the insertion of the pins 308.
[0037] After the pin 308 is passed through the L-shaped block 307 and placed inside the pin hole, both the first baffle 304 and the second baffle 305 can be fixed, ensuring that the first baffle 304 and the second baffle 305 will not rotate on their own when the slitting roller 106 and the feeding roller 107 are rotating.
[0038] Furthermore, the positioning mechanism 4 includes two blocking sleeves 401, which are slidably connected to the surface of the feeding roller 107. A screw 402 is threaded through the surface of the blocking sleeve 401, and a clamping plate 403 is rotatably connected to the bottom of the screw 402.
[0039] The blocking sleeve 401 can slide on the surface of the feeding roller 107, so that the two ends of the material on the surface of the feeding roller 107 can be limited and blocked by the blocking sleeve 401. Then, the screw 402 is rotated to press the surface of the clamping plate 403 against the surface of the feeding roller 107. At this time, the blocking sleeve 401 will be able to be fixed on the surface of the feeding roller 107. Through this design, the material can be prevented from moving left and right on the surface of the feeding roller 107 during the slitting process.
[0040] Furthermore, two grooves 404 are formed on the surface of the blocking sleeve 401, and a connecting block 405 is slidably connected to the surface of the groove 404. The surface of the connecting block 405 is fixedly connected to the surface of the clamping plate 403.
[0041] The clamping plate 403 can drive the connecting block 405 to slide inside the slide groove 404, which can ensure that the clamping plate 403 can move vertically up and down, and avoid the screw 402 driving the clamping plate 403 to rotate.
[0042] Working Principle: After the material is loaded onto the surfaces of the feeding roller 107 and the slitting roller 106, the motor 203 drives the bidirectional lead screw 204 to rotate. This allows the two driving plates 208 to move in opposite directions on the surfaces of the bidirectional lead screw 204 and the slide bar 205. When the driving plates 208 move, they also drive the outermost driven plate 206 to move. When the outermost driven plate 206 moves, the folding connecting rod 207 extends, allowing the multiple driven plates 206 to be equidistantly separated. This achieves equidistant adjustment of the distance between the multiple slitting blades 210, eliminating the need for operators to individually adjust the position of each slitting blade 210. This improves the device's adjustment efficiency and gives the slitting machine better working efficiency. Furthermore, the equidistant adjustment effect of this device is significantly better than manual adjustment. The accuracy of the cutting process is improved, preventing any misalignment of the slitting blade 210 due to human error or forgetfulness, resulting in better precision in the width of the material after slitting. After the slitting blade 210 is adjusted, the friction plate 215 can be brought into contact with the slide bar 205 by rotating the fastening knob 214, thus fixing the slitting blade 210 and further improving the accuracy of slitting. After slitting, the second cylinder 302 is activated, causing the slider 303 to move the first baffle 304 to the right, thereby disengaging the bearing ring 306 from the surfaces of the slitting roller 106 and the loading roller 107. Then, the first baffle 304 and the second baffle 305 are manually rotated to ensure that the right side of the slitting roller 106 and the loading roller 107 is unobstructed, allowing normal material loading operations to be performed on the surfaces of the slitting roller 106 and the loading roller 107.
[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
