[0002] Tape slitting machines are a type of mechanical equipment widely used in industries such as packaging, printing, and electronics. They mainly consist of an unwinding device, a traction device, a slitting device, and a rewinding device. The working principle is to use the traction device to transport the roll or sheet material from the unwinding device to the slitting device, where the blades cut it according to preset requirements. Then, the rewinding device rewinds the cut narrow strips of material, thereby achieving the function of slitting wide rolls or sheets into several narrow strips.
[0003] Currently, existing semi-automatic tape slitting machines have shortcomings in terms of cutting position and force adjustment. Their mechanical structure design is relatively fixed, and adjustment operations often require complex manual tools and cumbersome steps, making it difficult to fine-tune the cutting position and flexibly adjust the cutting force according to different material characteristics. This inevitably leads to situations where the cutting position is offset or the force is not suitable, resulting in material damage and serious insufficient slitting accuracy, which restricts production efficiency and finished product quality. Improvements are needed, and to this end, a cutting device for tape slitting machines is proposed. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figure 1-4 This utility model provides a technical solution:
[0028] A cutting device for a tape slitting machine includes a machine body 1, a conveyor roller 2 rotatably mounted on the machine body 1, a crossbar 3 above the conveyor roller 2, and evenly distributed slices 4 on the crossbar 3. Symmetrical cylinders 5 are fixedly mounted on the machine body 1, and symmetrical movable plates 6 are hinged to the side of the machine body 1. The output shaft ends of the cylinders 5 are respectively hinged to the sides of the movable plates 6. A connecting rod 7 is fixedly mounted between the ends of the two sets of movable plates 6, and the crossbar 3 is mounted on the connecting rod 7.
[0029] When in use, start the drive unit inside the machine body 1 to drive the conveyor roller 2 to rotate and convey the whole object to be cut. During the conveying process, the object is cut by the evenly distributed slices 4 on the crossbar 3.
[0030] When it is necessary to adjust the cutting position and force of the slice 4, the symmetrical cylinder 5 installed on the machine body 1 is activated simultaneously. The output shaft end of the cylinder 5 is hinged to the side of the movable plate 6. When the cylinder 5 is working, the output shaft extends and retracts, causing the movable plate 6 to rotate around the hinge point with the machine body 1. Since the connecting rod 7 is fixedly installed between the ends of the two sets of movable plates 6, and the crossbar 3 is set on the connecting rod 7, the rotation of the movable plate 6 will cause the connecting rod 7 to rise or fall, thereby causing the crossbar 3 and the slice 4 on the crossbar 3 to rise or fall synchronously. By precisely controlling the extension and retraction of the output shaft of the cylinder 5, the cutting position of the slice 4 can be easily and accurately adjusted. At the same time, as the height of the slice 4 changes, the pressure applied by the slice 4 to the cut material will also change accordingly when slitting the cut material, thereby realizing the adjustment of the cutting force and effectively avoiding problems such as material damage and insufficient slitting accuracy caused by cutting position deviation or improper force.
[0031] A symmetrical mounting block 8 is fixedly installed on the connecting rod 7. The mounting block 8 has an insertion port 9. Both ends of the crossbar 3 are fixedly installed with connecting blocks 10. The side of the connecting block 10 is fixedly installed with a plug plate 11. The size of the insertion port 9 is adapted to the size of the plug plate 11. The top surface of the mounting block 8 has a through opening 12. The side of the plug plate 11 has a threaded opening 13. The size of the through opening 12 is adapted to the size of the threaded opening 13. The mounting plate and the plug are fixedly installed with screws.
[0032] When it is necessary to replace the crossbar 3 and the slice 4, the operator uses a tool to unscrew the screws that pass through the opening 12 on the top surface of the mounting block 8 and the threaded opening 13 on the side of the insert plate 11. Since the size of the insert plate 11 matches the size of the socket 9, and the insert plate 11 is mounted on the connecting block 10 at the end of the crossbar 3, and the socket 9 is opened on the mounting block 8 on the connecting rod 7, after unscrewing the screws, the insert plate 11 can be pulled out from the socket 9, thereby separating the crossbar 3 from the connecting rod 7, and realizing the disassembly of the crossbar 3 and the slice 4. When it is necessary to install a new crossbar 3 and slice 4, align the insert plate 11 on the connecting block 10 at the end of the crossbar 3 with the socket 9 on the mounting block 8 and insert it so that the insert plate 11 is fully inserted into the socket 9. Then, through the through hole 12 on the top surface of the mounting block 8, screw the screw into the threaded hole 13 on the side of the insert plate 11 and tighten the screw. This will allow the crossbar 3 to be securely installed on the connecting rod 7, making it easy to disassemble and assemble the crossbar 3 and slice 4, and facilitating the replacement of slice 4 with different spacing and size.
[0033] The size of the insert plate 11 is compatible with the size of the socket 9, and a damping is provided between the insert plate 11 and the socket 9;
[0034] The size of the insert plate 11 is compatible with the size of the socket 9, and a damping is provided between the insert plate 11 and the socket 9. Therefore, when the insert plate 11 on the connecting block 10 at the end of the crossbar 3 is inserted into the socket 9 of the mounting block 8, the damping will generate a certain resistance, preventing the insert plate 11 from sliding freely in the socket 9. This ensures the stability of the crossbar 3 and the slice 4 after installation and fixation, thereby improving the cutting stability and ensuring the accuracy and quality of slitting.
[0035] A temperature sensor is installed inside the body 1, and a cooling fan is installed inside the body 1;
[0036] The temperature sensor installed inside the machine body 1 monitors the temperature inside the machine body 1 in real time. The cooling fan installed inside the machine body 1 is activated, and the rotation of the fan blades accelerates the airflow inside the machine body 1, carrying away the heat inside the machine body 1, thereby achieving heat dissipation inside the machine body 1 and preventing the temperature inside the machine body 1 from being too high, which would affect the normal working performance and service life of the various components of the slitting machine.
[0037] The side of the body 1 has evenly distributed heat dissipation holes 14;
[0038] The evenly distributed heat dissipation holes 14 on the side of the machine body 1 can work together with the cooling fan installed inside the machine body 1 to further enhance the heat dissipation effect inside the machine body 1 and provide a good environmental condition for the stable operation of the slitting machine.
[0039] A controller is installed on the body 1, and the controller is electrically connected to the body 1, cylinder 5, temperature sensor and cooling fan respectively;
[0040] Setting up a controller enables automatic control of the device components.
[0041] Working principle:
[0042] When in use, start the drive unit inside the machine body 1 to drive the conveyor roller 2 to rotate and convey the cutting material, i.e. the entire tape. During the conveying process, the tape is cut by the evenly distributed slices 4 on the crossbar 3.
[0043] When it is necessary to adjust the cutting position and force of the slice 4, the symmetrical cylinder 5 installed on the machine body 1 is activated simultaneously. The output shaft end of the cylinder 5 is hinged to the side of the movable plate 6. When the cylinder 5 is working, the output shaft extends and retracts, causing the movable plate 6 to rotate around the hinge point with the machine body 1. Since the connecting rod 7 is fixedly installed between the ends of the two sets of movable plates 6, and the crossbar 3 is set on the connecting rod 7, the rotation of the movable plate 6 will cause the connecting rod 7 to rise or fall, thereby causing the crossbar 3 and the slice 4 on the crossbar 3 to rise or fall synchronously. By precisely controlling the extension and retraction of the output shaft of the cylinder 5, the cutting position of the slice 4 can be easily and accurately adjusted. At the same time, as the height of the slice 4 changes, the pressure applied by the slice 4 to the cut object will also change accordingly when slitting the cut object, thereby realizing the adjustment of the cutting force and effectively avoiding problems such as material damage and insufficient slitting accuracy caused by cutting position deviation or improper force.
[0044] in,
[0045] When it is necessary to replace the crossbar 3 and the slice 4, the operator uses a tool to unscrew the screws that pass through the opening 12 on the top surface of the mounting block 8 and the threaded opening 13 on the side of the insert plate 11. Since the size of the insert plate 11 matches the size of the socket 9, and the insert plate 11 is mounted on the connecting block 10 at the end of the crossbar 3, and the socket 9 is opened on the mounting block 8 on the connecting rod 7, after unscrewing the screws, the insert plate 11 can be pulled out from the socket 9, thereby separating the crossbar 3 from the connecting rod 7, and realizing the disassembly of the crossbar 3 and the slice 4. When it is necessary to install a new crossbar 3 and slice 4, align the insert plate 11 on the connecting block 10 at the end of the crossbar 3 with the socket 9 on the mounting block 8 and insert it so that the insert plate 11 is fully inserted into the socket 9. Then, through the through hole 12 on the top surface of the mounting block 8, screw the screw into the threaded hole 13 on the side of the insert plate 11 and tighten the screw. The crossbar 3 can be securely installed on the connecting rod 7, which makes it easy to disassemble and assemble the crossbar 3 and slice 4, and facilitates the replacement of slice 4 with different spacing and size.
[0046] The size of the insert plate 11 is compatible with the size of the socket 9, and a damping is provided between the insert plate 11 and the socket 9. Therefore, when the insert plate 11 on the connecting block 10 at the end of the crossbar 3 is inserted into the socket 9 of the mounting block 8, the damping will generate a certain resistance, which will prevent the insert plate 11 from sliding freely in the socket 9. This ensures the stability of the crossbar 3 and the slice 4 after installation and fixation, thereby improving the cutting stability and ensuring the accuracy and quality of slitting.
[0047] The temperature sensor installed inside the machine body 1 monitors the temperature inside the machine body 1 in real time. The cooling fan installed inside the machine body 1 is activated. Through the rotation of the fan blades, the air flow inside the machine body 1 is accelerated, and the heat inside the machine body 1 is carried out, thereby achieving heat dissipation inside the machine body 1 and preventing the temperature inside the machine body 1 from being too high, which would affect the normal working performance and service life of the various components of the slitting machine.
[0048] The evenly distributed heat dissipation holes 14 on the side of the machine body 1 can work together with the cooling fan installed inside the machine body 1 to further enhance the heat dissipation effect inside the machine body 1 and provide a good environmental condition for the stable operation of the slitting machine.
[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
