[0002] A slitting machine is a mechanical device widely used in industrial production, mainly used for slitting materials such as wide-width paper, film, non-woven fabric, metal sheet, etc. into multiple narrow-width products.

[0003] The Chinese utility model patent with the publication number CN215854143U discloses a fully automatic PVC film slitting machine with adjustable width. After the material of this slitting machine is slit, it will exit from the inside of the slitting machine. When replacing with a new material roll, it is necessary to pass the material along the path inside the slitting machine through the slitting machine and finally reach the winding roller for winding; the material needs to bypass multiple roller shafts and slitting knife groups when passing through the inside of the slitting machine, so it takes a lot of time, and during this process, the slitting machine cannot be used normally, greatly reducing the working efficiency of the slitting machine.

[0004] Therefore, it is necessary to improve the slitting machine in the prior art. Content of the Utility Model

[0005] The purpose of the utility model is to overcome the defects existing in the prior art, and provide a slitting machine convenient for roll changing, which improves the working efficiency of the slitting machine.

[0006] To achieve the above purpose, the specific technical solution of the slitting machine convenient for roll changing of the utility model is as follows:

[0007] A slitting machine convenient for roll changing includes a roll changing mechanism. The roll changing mechanism includes a receiving platform.

[0023] The following combines the accompanying drawings and embodiments to further describe the detailed implementation mode of the present utility model. The following embodiments are only used to more clearly illustrate the technical solution of the present utility model, and cannot be used to limit the protection scope of the present utility model.

[0024] "Top surface", "bottom", "bottom surface" are referenced based on the normal use state of the slitting machine, only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation to the present utility model.

[0025] As Figure 3 and 4 shown, a slitting machine convenient for rewinding includes a rewinding mechanism 5. The rewinding mechanism 5 includes a material receiving platform 502. Two independently liftable clamping strips 501 are arranged on the top surface of the material receiving platform 502. Along the forward direction of the material inside the slitting machine is the first direction, the clamping strips 501 are arranged perpendicular to the first direction, and there is a gap for the material to pass between the clamping strips 501 and the material receiving platform 502.

[0026] The above slitting machine is used to slit a wide-width material into multiple narrow-width products. The slitting machine includes a base 2. A slitting cutter group 1 and a mounting frame 3 are fixedly connected to the base 2. The rewinding mechanism 5 and the material roller 4 are both installed on the mounting frame 3; the material is initially wound on the material roller 4. After unwinding, it passes through the rewinding mechanism 5 and the slitting cutter group 1 in sequence. After the material is slit into multiple narrow-width products by the slitting cutter group 1, it is wound by a winding machine, and thus the slitting of the material is completed; a lifting cylinder 504 is arranged on the material receiving platform 502. The lifting end of the lifting cylinder 504 is connected to the clamping strip 501 for driving the clamping strip 501 to lift. When the clamping strip 501 rises, there is a gap for the material to pass between the clamping strip 501 and the material receiving platform 502. When the clamping strip 501 falls, the material can be clamped from both sides by the clamping strip 501 and the material receiving platform 502 to realize the fixation of the material.

[0027] During the operation of the above slitter, when the material on the material roll 4 is cut, the end of the material detaches from the material roll 4. When the end of the material passes above the material receiving platform 502, the end of the material can be clamped by the clamping strip 501 located in front of the advancing direction of the material. Then, a new material roll 4 is replaced. After unrolling the material on the material roll 4, the front end of the material is moved above the material receiving platform 502, and the front end of the material is clamped by another clamping strip 501. Then, the head and tail ends of the two materials are butted on the material receiving platform, and adhesive tape is used for bonding and fixing at the butting moment. After the butting is completed, the two clamping strips 501 are loosened, and at the same time, the slitter is started to operate normally, so that the latter material can be driven forward by the former material to realize continuous slitting of the material.

[0028] With the assistance of the roll changing mechanism 5, the slitter can realize the head-to-tail butting between the front and rear rolls of materials, and drive the latter material forward by the former material to realize continuous slitting of the material by the slitter. Compared with the situation after replacing the material, it is necessary to pass the material completely through the entire slitter along the path of the material advancing inside the slitter, which saves more time, thereby shortening the downtime of the slitter and improving the working efficiency of the slitter.

[0029] A further improvement is that, as Figure 3 and 4 shown, guide rollers 505 are arranged on both the front and rear sides of the material receiving platform 502 along the first direction. The axis line of the guide roller 505 is parallel to the clamping strip 501, and the horizontal height of the top of the guide roller 505 is greater than the horizontal height of the top surface of the material receiving platform 502. The arrangement of the two guide rollers 505 can support the material passing above the material receiving platform 502, and reduce the resistance of the material advancing through the rolling friction between the material and the guide rollers 505. The horizontal height of the top of the guide roller 505 being greater than the horizontal height of the top surface of the material receiving platform 502 can reduce the friction between the material and the material receiving platform 502 when the material advances, reduce the wear on the material, and improve the quality of the material.

[0030] A further improvement is that, as Figure 5 and 6 shown, the side edges on both the front and rear sides of the material receiving platform 502 along the first direction are bent downward to form a bent portion 506, and the bent portion 506 and the material receiving platform 502 are transitioned by an arc. The bent portion 506 and the material receiving platform 502 are perpendicularly distributed. The bent portion 506 can improve the strength of the material receiving platform 502 in the direction perpendicular to the first direction, thereby improving the bearing capacity of the material receiving platform 502. The arc can make the connection part between the bent portion 506 and the material receiving platform 502 smoother, thereby reducing the probability of damaging the material and ensuring the quality of the materials produced by the slitter.

[0031] A further improvement is that, as Figure 6As shown, a support bar 507 is fixedly connected to the bottom surface of the material receiving platform 502, and the support bar 507 is fixedly connected to the bent portion 506. The support bar 507 supports the material receiving platform 502 from the bottom, further enhancing the strength of the material receiving platform 502, reducing the probability of deformation of the material receiving platform 502, and enhancing the firmness of clamping the material by the material receiving platform 502 and the clamping bar 501.

[0032] A further improvement is that, as Figures 4-6 shown, the material receiving platform 502 is provided with a guide groove 503, and the guide groove 503 is located between the two clamping bars 501. When docking the front and rear ends of the material on the material receiving platform 502, the ends of the material need to be cut flat to improve the docking quality; the provided guide groove 503 can play a role in guiding and positioning the cutting tool during material cutting, thereby improving the flatness of the cut material, improving the quality of material docking, and further improving the quality of material cutting by the cutting machine.

[0033] A further improvement is that, as Figures 1-3 shown, the mounting frame 3 is slidably connected to the base 2 perpendicular to the first direction. When docking the front and rear rolls of material, there may be a misalignment between the two rolls of material. Therefore, after loosening the end of the front roll of material, the position of the mounting frame 3 can be moved along the direction perpendicular to the first direction, so that the end of the rear roll of material fixed on the mounting frame 3 is aligned with the end of the front roll of material. Then, fix the ends of the front and rear rolls of material and perform docking and fixing, thereby improving the docking accuracy and the quality of material cutting by the cutting machine.

[0034] A further improvement is that, as Figures 1-3 shown, a slide rail 201 is fixedly connected to the base 2 perpendicular to the first direction. A slide block 301 is slidably engaged with the slide rail 201, and the slide block 301 is fixedly connected to the mounting frame 3. A deviation correction actuator 6 for driving the mounting frame 3 to slide is further provided on the base 2. The deviation correction actuator 6 is a push-pull cylinder, and both ends of the push-pull cylinder are respectively hinged to the base 2 and the mounting frame 3. The cooperation between the slide block 301 and the slide rail 201 plays a guiding role in the movement of the mounting frame 3. When adjusting the position of the mounting frame 3, the push-pull cylinder provides power to drive the mounting frame 3 to move on the base 2, thereby adjusting the position of the rear roll of material and realizing the precise docking of the ends of the front and rear rolls of material.
