Detailed implementation manners

[0029] The following combines the drawings and embodiments to further describe the detailed implementation manners of the present utility model. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model, and cannot be used to limit the protection scope of the present utility model.

[0030] "Top surface", "bottom", "bottom surface" are referenced based on the normal use state of the slitting device, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model.

[0031] Such as Figures 1-6As shown, a slitting device with a tool switching function includes a frame 1; a plurality of rollers 5 are arranged on the frame 1, and are used to guide the material to advance along a first path 6; a circular knife group 3, including a second rotating shaft 307 provided with an upper knife disc 305 and a first rotating shaft 301 provided with a lower knife groove 306, the upper knife disc 305 is a circular knife, at least the second rotating shaft 307 of the first rotating shaft 301 and the second rotating shaft 307 is slidably connected to the frame 1, and the first path 6 passes between the first rotating shaft 301 and the second rotating shaft 307; a straight knife group 2, including a knife seat 201 and a blade 205 installed on the knife seat 201, the blade 205 is a straight knife, the knife seat 201 is arranged adjacent to the first path 6, and the knife seat 201 is rotatably connected to the frame 1 for adjusting the position of the blade 205.

[0032] When the above-mentioned slitting machine is used, the setting of multiple rollers 5 can make the material bypass each roller 5, thereby guiding the material forward path; in the slitting machine, the material is guided by each roller 5 along the path of the material. Figure 4 The first path 6 shown in the figure moves forward. During the material moving forward, the material passes through the circular knife group 3 and the straight knife group 2; the upper knife disc 305 of the circular knife group 3 is arranged at equal intervals along the axial direction of the second rotating shaft 307, and the lower knife groove 306 is arranged at equal intervals along the axial direction of the first rotating shaft 301. The lower knife groove 306 corresponds to the upper knife disc 305 one by one. When the material passes between the lower knife groove 306 and the upper knife disc 305 along the first path 6, the side wall of the lower knife groove 306 cooperates with the upper knife disc 305 to achieve shearing of the material, thereby cutting the material into multiple narrow products; the second rotating shaft 307 of the circular knife group 3 is slidably connected to the frame 1, and the distance between the second rotating shaft 307 and the first path 6 can be adjusted, thereby realizing the contact and separation of the upper knife disc 305 and the material. When the upper knife disc 305 contacts the material, Effective cutting, when the upper knife disc 305 is separated from the material, the lower knife groove 306 alone cannot cut the material, so the first rotating shaft 301 can be used as a guide at this time; when the knife seat 201 of the straight knife group 2 rotates, the position of the blade 205 on the knife seat 201 can be changed. When the blade 205 rotates to the side close to the first path 6, the blade 205 contacts the material to cut the material. When the blade 205 rotates to the side away from the first path 6, the blade 205 is separated from the material; by controlling the blade 205 and the upper knife disc 305 to contact or stay away from the material, the switching between the blade 205 and the upper knife disc 305 can be achieved, so that the slitting machine can flexibly select the blade 205 or the upper knife disc 305 to cut the material according to the different cutting materials, which greatly improves the practicality and convenience of use of the slitting machine.

[0033] A further improvement is, Figure 1 and 2As shown, there are two frames 1. The roller shaft 5, the first rotating shaft 301, the second rotating shaft 307 and the tool holder 201 are pairwise parallel to each other, and both ends are rotatably connected to the two frames 1 through bearings. The frame 1 is provided with a power unit 4 for driving the roller shaft 5, the first rotating shaft 301 and the second rotating shaft 307 to rotate. The setting of the two frames 1 can stably support both ends of the roller shaft 5, the first rotating shaft 301, the second rotating shaft 307 and the tool holder 201, thereby improving their stability. The power unit 4 includes a motor and gears. The gears are arranged at the ends of the roller shaft 5, the first rotating shaft 301 and the motor drive shaft. Powered by the motor, under the driving action of each gear, the roller shaft 5 and the first rotating shaft 301 are driven to rotate. Transmission gears 302 that mesh with each other are arranged at both ends of the first rotating shaft 301 and the second rotating shaft 307. In this way, the second rotating shaft 307 can be driven to rotate by the first rotating shaft 301.

[0034] A further improvement is that, as Figure 3 and 6 shown, mounting seats 303 are connected to both ends of the first rotating shaft 301 and the second rotating shaft 307 through bearings. The frame 1 is provided with a slot 103 into which the mounting seat 303 can enter. The frame 1 is also provided with a locking member for locking the mounting seat 303. The mounting seat 303 slides inside the slot 103, enabling the adjustment of the position of the first rotating shaft 301, and further enabling the adjustment of the distance between the upper tool disc 305 and the material. The setting of the locking member is used to fix the second rotating shaft 307 or the relative position between the first rotating shaft 301 and the second rotating shaft 307, thereby achieving the positioning of the first rotating shaft 301 and the second rotating shaft 307 and improving the stability of the equipment operation.

[0035] A further improvement is that, as Figure 6 shown, the mounting seat 303 is provided with a limiting groove 304, and the side of the slot 103 is slidably arranged inside the limiting groove 304. The limiting groove 304 and the side of the slot 103 are mutually limited, which can improve the firmness of the mounting seat 303 installed inside the slot 103 and further improve the stability of the equipment operation.

[0036] A further improvement is that, as Figure 3As shown in the figure, one end of the slot 103 has an opening communicating with the outside of the slot 103. The locking member includes a cover plate 102 detachably arranged at the opening. A locking screw 101 is threadedly connected to the cover plate 102, and the front end of the locking screw 101 abuts against the mounting seat 303. In this slitting device, the cover plate 102 is connected to the machine frame 1 by screws. When the cover plate 102 is opened, the mounting seat 303 can be taken out from the inside of the slot 103, and then the maintenance and replacement of the upper cutter head 305 or the lower cutter groove 306 can be completed. The setting of the locking screw 101 can, when the upper cutter head 305 cuts materials, press tightly the mounting seat 303 on the first rotating shaft 301 and the second rotating shaft 307, so that the upper cutter head 305 and the lower cutter groove 306 are tightly connected, ensuring the slitting effect on the materials. When it is not necessary to use the upper cutter head 305 to cut materials, the locking screw 101 can be loosened, so that the first rotating shaft 301 and the second rotating shaft 307 can slide inside the slot 103. In order to facilitate the mounting seat 303 to stay at different positions inside the slot 103, the inner bottom wall of the slot 103 can be in a horizontal state. In this way, the mounting seat 303 can stay at different positions inside the slot 103 under the action of the friction force between the mounting seat 303 and the inner wall of the slot 103 and is not prone to sliding.

[0037] A further improvement is that, as Figure 5 shown in the figure, the machine frame 1 is provided with a driving unit 206 for driving the tool holder 201 to rotate. An installation groove 202 is formed on one side of the tool holder 201 along its extending direction, and the blade 205 is detachably connected to the installation groove 202. The driving unit 206 includes a gear arranged at the end of the tool holder 201, a worm gear matching the gear, and a hand wheel arranged at the end of the worm gear. By rotating the hand wheel, the tool holder 201 can be driven to rotate, so as to adjust the position of the blade 205 on the tool holder 201 and realize the switching of the blade 205.

[0038] A further improvement is that, as Figure 5 shown in the figure, a plurality of blade pads 204 are slidably arranged in the installation groove 202. There is an interval for placing the blade 205 between two adjacent blade pads 204. At least one end of the two ends of the tool holder 201 is provided with a fastener for pressing each blade pad 204; the fastener includes a bolt 203 arranged along the extending direction of the tool holder 201. The bolt 203 is threadedly connected to the tool holder 201, and the front end of the bolt 203 abuts against the blade pad 204. Bolts 203 are arranged at both ends of the tool holder 201. By adjusting the two bolts 203 simultaneously, the positions of the blade pads 204 and the blade 205 inside the installation groove 202 can be adjusted, so as to realize the adjustment of the position of the blade 205. It can also realize the clamping and loosening operations of the blade pads 204, so as to realize the fastening and loosening of the blade 205 and improve the convenience of blade 205 replacement; by installing the blade 205 between two different blade pads 204, the interval between the blades 205 can be adjusted, so as to realize the adjustment of the width of the product after cutting.

[0039] A further improvement is that, as Figure 1 , 2 and shown in FIG. 4, two of the roller shafts 5 are arranged adjacent to the tool holder 201, and the tool holder 201 and the roller shafts 5 are respectively located on both sides of the first path 6. The arrangement of the roller shafts 5 can support the material and keep the material in a tensioned state, thereby improving the cutting effect of the blade 205 on the material.

[0040] A further improvement is that, as Figure 4 shown, the material further has a second path 7, and the second path 7 bypasses from the side of the first rotating shaft 301 away from the second rotating shaft 307 and is arranged adjacent to the tool holder 201. The part of the material on the second path 7 in contact with the circular knife group 3 is different from that on the first path 6. When cutting the same roll of material, if different cutting requirements require tool switching, the switching between the blade 205 and the upper tool plate 305 can be achieved by rotating the tool holder 201 or moving the second rotating shaft 307; if the materials being cut are from different material rolls and have different cutting requirements between different material rolls, the switching between the blade 205 and the upper tool plate 305 can be achieved by advancing different material rolls along the first path 6 or the second path 7; when the material advances along the first path 6, the material passes between the upper tool plate 305 and the lower tool groove 306, and when the blade 205 is rotated to a state of being separated from the material, the state of cutting the material with the upper tool plate 305 can be switched; when the material advances along the second path 7, the material is separated from the upper tool plate 305, and when the blade 205 is rotated to a state of being in contact with the material, the state of cutting the material with the blade 205 can be switched.
