Description

Technical Field

[0001] The present invention relates to the technical field of slitting machines, and particularly to a double-label stationery tape slitting machine. Background Art

[0002] A slitting machine is a device for longitudinally slitting wide coil materials. Its main function is to cut the wide coil materials into narrow coils of a certain size in the length direction. The slitting machine can slit the tape and then use a winding roller to wind the slit tape for subsequent processing. When in use, since the traditional tape slitting machine adjusts the slitting size according to different cutting requirements and cuts off the irregular sides during use, manual adjustment is required when slitting tapes of different sizes, resulting in low flexibility during the overall slitting process.

[0003] In order to overcome the above defects, the prior art (a Chinese patent with the publication number CN217376634U and the publication date of September 6, 2022) is a slitting machine for tape processing, which relates to the technical field of tape processing. The present invention includes a slitting device, a top sheet, a connecting frame, a cutting structure and an air shaft. The slitting device is detachably connected to one side of the connecting frame, and a top sheet, a cutting structure and an air shaft are detachably connected to the connecting frame. A support rod and a support plate are fixedly connected to the top of the bottom plate. A motor, a fixed rod and a cylinder part are connected to the inner side of the support plate. An arc plate is fixedly connected to the inner side of the connecting piece. A rodless cylinder is detachably connected to the outer wall of the arc plate. A cutter is detachably connected to the output end of the rodless cylinder. A jack is penetrated and opened on the connecting piece. By connecting a top sheet and a cutting structure on the connecting frame, the problems that the existing tape processing slitting machine is not convenient for the user to cut and separate the stored tape from the slitting device and the existing tape processing slitting machine is not convenient for the user to quickly separate the stored tape from the storage device are solved.

[0004] The above mechanism can separate the tape from the slitting device by using the cutter and the cutting structure. However, in the actual use process, the tape is sleeved outside the winding roller through a fixed roller. When winding, the winding roller can be removed and the tape can be moved to one side and removed. However, the prior art is not flexible enough in adjusting the slitting width of the tape, and at the same time, the irregular sides cannot be cut off by the slitting mechanism, resulting in low applicability during the overall use. Summary of the Invention

[0005] The purpose of the present invention is to provide a double-label stationery tape slitting machine to solve the problem that the traditional tape slitting machine adjusts the slitting size according to different cutting requirements and cuts off the irregular sides during use, and manual adjustment is required when slitting tapes of different sizes, resulting in low flexibility during the overall slitting process as mentioned in the above background art.

[0006] To achieve the above object, the present invention provides the following technical solution: A double-label stationery tape slitting machine, including a fixed bottom plate, a fixed frame is fixedly connected to the top end of the fixed bottom plate, and a pay-off roller is rotatably connected to one side between the inner parts of the fixed frame. A servo motor is installed on the outside of the fixed frame, and the output end of the servo motor is connected to the pay-off roller through a coupling. A tension roller is rotatably connected to one side of the fixed bottom plate close to the fixed frame, and a take-up roller is installed on the side of the fixed bottom plate far from the fixed frame; A threaded rod is rotatably connected to one side between the fixed frames, and a width adjustment mechanism for adjusting the slitting size is arranged on the outside of the threaded rod. The width adjustment mechanism includes a fixed block, and the fixed block is sleeved on the outside of the threaded rod. Both sides of the outside of the threaded rod are threadedly connected with movable blocks, and cutting knives are arranged at the bottom ends of the fixed block and the movable blocks; The top ends of the fixed block and the movable block are hinged with a hinge spring, and the top end of the hinge spring is hinged with a movable plate. Cleaning mechanisms for cleaning the outside of the threaded rod are arranged on both sides of the bottom end of the movable plate.

[0007] Further, sliding grooves are opened on both sides of the inside of the fixed frame, and sliding blocks matched with the sliding grooves are fixedly connected to both sides of the movable plate. The movable plate and the fixed frame are slidably connected through the sliding grooves and the sliding blocks to form a sliding mechanism.

[0008] Further, hinge frames are fixedly connected to the bottom ends of the fixed block and the movable block, and a cutting knife is rotatably connected to the inner side of the hinge frame. Torsion springs are wound around both sides of the cutting knife, and an elastic structure is formed between the cutting knife and the hinge frame.

[0009] Further, the bottom end of the cutting knife is attached to the outside of the pay-off roller, and the pay-off roller is arranged below the threaded rod.

[0010] Further, the distance between the tension roller and the fixed bottom plate is greater than the distance between the pay-off roller and the fixed bottom plate, and the distance between the take-up roller and the fixed bottom plate is less than the distance between the tension roller and the fixed bottom plate.

[0011] Further, the cleaning mechanism includes an elastic air bag. The elastic air bag is installed on both sides of the bottom end of the movable plate through springs. A jet nozzle is installed on the side of the elastic air bag through a hose. Cams are rotatably connected to both sides of the pay-off roller through a sprocket mechanism, and the cams are rotatably connected to the side wall inside the fixed frame.

[0012] Further, the cam is arranged below the elastic air bag, and the jet nozzle is arranged on the side of the threaded rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The rotation of the threaded rod is driven by a motor. The fixed block is sleeved outside the threaded rod, and the movable block is threadedly connected to the threaded rod, enabling the movable block to move on the left and right sides outside the threaded rod. During the movement of the movable block, the contact position between the cutting knife and the tape is adjusted, thereby realizing the adjustment of the size of the slit tape. The position of the cutting knife at the lower end of the fixed block is fixed, so that the size of the tape slit between the fixed block and the movable block remains consistent.

[0015] Further, when the movable block moves to the side of the threaded rod and the tape is slit by the cutting knife, the redundant and irregular positions on the side can be cut off, reducing the defective products of the tape.

[0016] Furthermore, the movable plate moves up and down due to the adjustment of the slit width. Through the mutual cooperation of the chute and the slider, the up and down movement of the movable plate can be kept stable, and further the angles of the fixed block and the movable block are also restricted.

[0017] 2. During the slitting process, the height of the movable plate remains fixed. The output end of the servo motor can drive the cam to rotate through the sprocket transmission mechanism. When the cam rotates, it continuously squeezes the elastic airbag. After the elastic airbag is squeezed, the gas inside is transported to the jet nozzle through the hose. The angle of the jet nozzle can be adjusted, so the jet nozzle can clean the thread groove outside the threaded rod, reducing the dust residue on the thread groove outside the threaded rod.

[0018] Further, the bottom end of the movable block is rotatably connected with a cutting knife through a hinge frame. The bottom end of the cutting knife is in contact with the tape outside the unwinding roller, and due to the elastic force of the torsion spring, the cutting knife exerts a certain pressure on the tape outside the unwinding roller. Since the elastic force of the torsion spring is limited, when the tape outside the unwinding roller is slit, the cutting knife will not press too deep and cause cutting jams. At the same time, through the elastic force of the torsion spring itself, the cutting knife can always be in contact with the tape outside the unwinding roller to achieve slitting.

Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Embodiment 1: As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6The shown technical solution is to solve the problem that when the traditional tape slitting machine is in use, it adjusts the slitting size according to different cutting requirements and cuts off the irregular sides. When slitting tapes of different sizes, manual adjustment is required, resulting in low flexibility during the overall slitting process: This double-identification stationery tape slitting machine discloses a width adjustment mechanism, including a fixed bottom plate 1. A fixed frame 2 is fixedly connected to the top end of the fixed bottom plate 1. One side between the inner parts of the fixed frame 2 is rotatably connected with a unwind roller 3. A servo motor 15 is installed on the outside of the fixed frame 2, and the output end of the servo motor 15 is connected to the unwind roller 3 through a coupling. A tension roller 12 is rotatably connected to one side of the top end of the fixed bottom plate 1 close to the fixed frame 2. A winding roller 13 is installed on the side of the top end of the fixed bottom plate 1 far from the fixed frame 2; One side between the fixed frames 2 is rotatably connected with a threaded rod 4, and a width adjustment mechanism for adjusting the slitting size is arranged on the outside of the threaded rod 4. The width adjustment mechanism includes a fixed block 5, and the fixed block 5 is sleeved on the outside of the threaded rod 4. Both sides of the outside of the threaded rod 4 are threadedly connected with movable blocks 6, and cutting knives 8 are arranged at the bottom ends of the fixed block 5 and the movable blocks 6; Sliding grooves 18 are opened on both sides inside the fixed frame 2, and both sides of the movable plate 11 are fixedly connected with sliders 19 that match the sliding grooves 18. The sliding connection between the movable plate 11 and the fixed frame 2 through the sliding grooves 18 and the sliders 19 constitutes a sliding mechanism; The distance between the tension roller 12 and the fixed bottom plate 1 is greater than the distance between the unwind roller 3 and the fixed bottom plate 1, and the distance between the winding roller 13 and the fixed bottom plate is less than the distance between the tension roller 12 and the fixed bottom plate 1.

[0028] In this example, the output end of the servo motor 15 rotates to drive the unwinding roller 3 to rotate. When the unwinding roller 3 rotates, it can unwind the tape. The tape passes through the tension roller 12 and is slit by the cutting knife 8, and then the tape is wound around the outside of the winding roller 13. The winding roller 13 can wind the tape; the motor drives the threaded rod 4 to rotate. The fixed block 5 is sleeved on the outside of the threaded rod 4, and the movable block 6 is threadedly connected to the threaded rod 4, so that the movable block 6 can move on the left and right sides outside the threaded rod 4. During the movement of the movable block 6, the contact position between the cutting knife 8 and the tape will be adjusted, so as to realize the adjustment of the size of the slit tape. The position of the cutting knife 8 at the lower end of the fixed block 5 is fixed, so that the sizes of the tapes slit between the fixed block 5 and the movable block 6 are kept consistent; when the movable block 6 moves to the side of the threaded rod 4 and the tape is slit by the cutting knife 8 again, the redundant and irregular positions on the side can be cut off, reducing the defective products of the tape; by the mutual cooperation between the movable plate 11 and the hinge spring 10, the movable block 6 keeps its own angle fixed even during the movement, and it is not easy to have the situation of angle deviation. The movable plate 11 will move up and down by itself due to the adjustment of the slitting width. Through the mutual cooperation of the chute 18 and the slider 19, the up and down movement of the movable plate 11 can be kept stable, and further the angles of the fixed block 5 and the movable block 6 are also restricted.

[0029] Embodiment 2: As Figures 1-4 shown in the technical solution, to solve the problem that dust will remain in the thread grooves on the surface of the threaded rod 4 during long-term use, and excessive dust residue will cause the movable block 6 to wear the threaded rod 4 during the movement, affecting the overall service life: This double-label stationery tape slitting machine discloses a cleaning mechanism. The top ends of the fixed block 5 and the movable block 6 are hinged with a hinge spring 10, and the top end of the hinge spring 10 is hinged with a movable plate 11. Cleaning mechanisms for cleaning the outside of the threaded rod 4 are arranged on both sides of the bottom end of the movable plate 11; the cleaning mechanism includes elastic air bags 14. The elastic air bags 14 are installed on both sides of the bottom end of the movable plate 11 through springs. Nozzles 17 are installed on the sides of the elastic air bags 14 through hoses. Both sides of the unwinding roller 3 are rotationally connected with cams 16 through a sprocket mechanism, and the cams 16 are rotationally connected to the side walls inside the fixed frame 2; the cams 16 are arranged below the elastic air bags 14, and the nozzles 17 are arranged on the side of the threaded rod 4.

[0030] In this example, since the height of the movable plate 11 remains fixed during the slitting process, the output end of the servo motor 15 can drive the cam 16 to rotate through a sprocket transmission mechanism. When the cam 16 rotates, it continuously squeezes the elastic airbag 14. After the elastic airbag 14 is squeezed, the gas inside is transported through a hose to the jet nozzle 17. The angle of the jet nozzle 17 can be adjusted, so the jet nozzle 17 can clean the thread groove outside the threaded rod 4, reducing the residue of dust on the thread groove outside the threaded rod 4; check valves are provided at both the air inlet and the air outlet of the elastic airbag 14, which can prevent the elastic airbag 14 from sucking dust and gas back from the jet nozzle 17 into the inside of the elastic airbag 14 when inhaling air. At the same time, the air inlet opened on the elastic airbag 14 can also inflate again after the elastic airbag 14 is repeatedly squeezed and continue to clean the thread groove outside the threaded rod 4; the elastic airbag 14 is connected to the movable plate 11 through a spring. Therefore, after the elastic airbag 14 is squeezed, it will automatically reset through the elastic force of the spring and exhaust air.

[0031] Embodiment 3: As Figure 1 , Figure 3 and Figure 5 shown in the technical solution, in order to solve the problem that the depth of contact between the cutting knife 8 and the tape is prone to deviation during tape slitting: This double-identification stationery tape slitting machine discloses a cutting mechanism. The bottom ends of the fixed block 5 and the movable block 6 are both fixedly connected with hinge frames 7, and a cutting knife 8 is rotatably connected inside the hinge frames 7. Torsion springs 9 are wound around both sides of the cutting knife 8, and an elastic structure is formed between the cutting knife 8 and the hinge frames 7; the bottom end of the cutting knife 8 is in contact with the outer side of the unwinding roller 3, and the unwinding roller 3 is arranged below the threaded rod 4.

[0032] In this example, the bottom end of the movable block 6 is rotatably connected with a cutting knife 8 through a hinge frame 7. The bottom end of the cutting knife 8 is in contact with the tape outside the unwinding roller 3, and due to the elastic force of the torsion spring 9, the cutting knife 8 applies a certain pressure to the tape outside the unwinding roller 3. Since the elastic force of the torsion spring 9 is limited, when the tape outside the unwinding roller 3 is slit, the cutting knife 8 will not press too deeply and cause cutting jams. At the same time, through the elastic force of the torsion spring 9 itself, the cutting knife 8 can always be in contact with the tape outside the unwinding roller 3 to achieve slitting.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
