Technical Field

[0001] The utility model relates to the technical field of slitting machines, in particular to a slitting machine applied to the splitting and rewinding of PET materials. Background Art

[0002] A slitting machine is a mechanical device that longitudinally cuts a wide strip of material into multiple narrow strips. Slitting machines are widely used in the splitting of PET materials, insulating materials, and various PP film materials. While splitting the coil material through the slitting machine, it can also rewind the split materials, greatly improving the slitting efficiency.

[0003] The patent with the publication number CN220502218U discloses a "multifunctional PET tape slitting machine, including a slitting machine body. Inside the slitting machine body, there are cutting tools, a winding roller located at the top of the cutting tools, and a pressing roller located in front of the cutting tools; through the use of the cleaning device in the utility model, the cleaning device cleans the residual sticky glue on the surface of the cutting tools, reduces the uneven slitting of the PET tape caused by the residual sticky glue on the surface of the cutting tools, and thus improves the working efficiency of the slitting machine body."

[0004] Regarding the above related technologies, the inventor believes that the distance between the cutting tools and the PET coil cannot be adjusted. Therefore, for the splitting requirements of PET coils with different thickness specifications, cutting tools with corresponding size specifications need to be replaced, and when replacing the cutting tools, the roller of the tool needs to be disassembled and assembled, which is rather inconvenient to operate. Summary of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the utility model provides a slitting machine applied to the splitting and rewinding of PET materials. The specific technical solutions are as follows:

[0006] A slitting machine applied to the splitting and rewinding of PET materials includes a machine body, a carrying roller rotatably arranged inside the machine body and used for carrying the PET coil during splitting, a splitting mechanism rotatably arranged inside the machine body for splitting the coil on the carrying roller, and a rewinding mechanism arranged inside the machine body for rewinding the split coil. The splitting mechanism includes a splitting roller arranged inside the machine body and a plurality of splitting components detachably arranged on the outer wall of the splitting roller. An adjusting mechanism for controlling the distance between the splitting roller and the coil on the carrying roller is arranged inside the machine body;

[0007] The adjusting mechanism includes a rotating rod rotatably arranged at both ends inside the machine body, two groups of connecting plates fixedly arranged on the outer walls at both ends of the rotating rod.

[0010] Through the rotation of the winding roller, the coil on the unwinding roller can be rewound to the outside of the winding roller, enabling the neatly arranged discharging of the divided coils and facilitating the blanking.

[0011] Optionally, the dividing assembly includes an installation ring slidably arranged on the outer wall of the dividing roller, and a dividing knife fixed on the outer wall of one end of the installation ring for dividing the coil. A spring is fixed on the outer wall of the installation ring, and a grip plate for people to hold is provided at one end of the spring. A plurality of pin holes are evenly distributed on the outer wall of the dividing roller, a pin rod is provided at the end of the grip plate close to the spring, and one end of the pin rod penetrates through the installation ring and is inserted into the pin hole of the dividing roller in a matching manner.

[0012] Through the rotation of the dividing roller, it can drive the dividing assembly to divide the PET coil on the carrying roller, and the rewinding roller rewinds the divided coil, improving the production efficiency.

[0013] Optionally, a suction cup for adsorbing the dividing roller is fixed between the spring and the grip plate, one end of the pin rod is fixedly arranged inside the suction cup, and a counterweight block is fixed at the end of the dividing roller away from the grip plate.

[0014] Through the pulling force of the spring and the suction force of the suction cup, the pin rod can be inserted into the corresponding pin hole on the dividing roller to fix the slid dividing assembly, improving the stability during division.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] (1) Through the rotation of the dividing roller, it can drive the dividing assembly to divide the PET coil on the carrying roller, and the rewinding roller rewinds the divided coil, improving the production efficiency. After the cylinder expands and contracts, it will drive the overall rotation of components such as the rotating rod and the winding roller, thereby adjusting the distance between the winding roller and the PET coil, facilitating the slitting of PET coils with different thickness specifications. It has a wide range of applications, and there is no need to replace the dividing assembly with corresponding sizes when slitting coils of different thicknesses, which is convenient and fast.

[0017] (2) By sliding the dividing components on the dividing roller, the positions of dividing components such as dividing knives can be changed, facilitating the division of the PET coil into different widths. Moreover, under the pulling force of the spring and the suction force of the suction cup, the pin rod can be inserted into the corresponding pin holes on the dividing roller to fix the slid dividing components, improving the stability during division.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] 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 of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-4 , a slitting and rewinding machine for dividing and rewinding PET materials, including a machine body 1, a carrying roller 2 rotatably arranged in the machine body 1 and used for carrying the PET coil during division, a dividing mechanism rotatably arranged in the machine body 1 for dividing the coil on the carrying roller 2, and a rewinding mechanism arranged in the machine body 1 for rewinding the divided coil. The machine body 1 can support components such as the dividing mechanism. The PET coil is a coil made of PET material, such as a PET tape.

[0025] Please refer to Figures 1-2, the rewinding mechanism includes a winding roller 12 rotatably arranged inside one end of the machine body 1 for winding the PET coil, and a unwinding roller 11 rotatably arranged inside the other end of the machine body 1 for unwinding the PET coil. A motor for driving is provided on one side of the winding roller 12. After the winding roller 12 rotates, the coil on the unwinding roller 11 will be rewound to the outside of the winding roller 12, so that the coils can be neatly discharged after being separated, facilitating the feeding.

[0026] Please refer to Figures 1-2 , several guide rollers 13 for guiding the coil are rotatably arranged in the middle of the inner side of the machine body 1. The carrier roller 2 is located between the guide roller 13 and the winding roller 12. The guide roller 13 and the carrier roller 2 can guide and limit the coil, and the carrier roller 2 can carry and support the coil during splitting.

[0027] Please refer to Figures 1-2 , the splitting mechanism includes a splitting roller 3 arranged in the machine body 1 and several splitting components detachably arranged on the outer wall of the splitting roller 3. The splitting component includes an installation ring 4 slidably arranged on the outer wall of the splitting roller 3 and a splitting knife 41 fixedly arranged on the outer wall of one end of the installation ring 4 for splitting the coil. A motor for driving is provided at one end of the splitting roller 3. The driving of the motor for the winding roller 12 and the splitting roller 3 is a public technology and is a common structure in existing slitting machines, so it will not be elaborated here. After the installation ring 4 is installed on the outer wall of the splitting roller 3, it will rotate together with the splitting roller 3, thereby driving the rotating splitting knife 41 to split the coil on the carrier roller 2.

[0028] Please refer to Figures 2-3 , a spring 42 is fixedly arranged on the outer wall of the installation ring 4, and a grip plate 43 for people to hold is provided at one end of the spring 42. Under the pulling force of the spring 42, the grip plate 43 will be pulled towards the installation ring 4.

[0029] Please refer to Figures 2-3 , a number of pin holes are evenly distributed on the outer wall of the splitting roller 3. One end of the grip plate 43 close to the spring 42 is provided with a pin rod 44. One end of the pin rod 44 penetrates through the installation ring 4 and is inserted into the pin hole of the splitting roller 3 in a matching manner. Under the pulling force of the spring 42, one end of the pin rod 44 will be inserted into the corresponding pin hole, thereby connecting and fixing between the installation ring 4 and the splitting roller 3 and fixing the split splitting component.

[0030] Please refer to Figures 2-3A suction cup 45 for adsorbing the splitting roller 3 is fixedly provided between the spring 42 and the gripping plate 43, and one end of the pin rod 44 is fixedly provided in the suction cup 45. The suction cup 45 can be an existing curved suction cup for adsorbing arc-shaped objects. The suction cup 45 can connect the spring 42 and the gripping plate 43, and the suction cup 45 can shield and protect the internal spring 42. After the suction cup 45 adsorbs the splitting roller 3, the tension of the spring 42 can improve the stability of the pin rod 44 plugging into the pin hole, so that when the splitting roller 3 rotates, the pin rod 44 will not be separated from the pin hole due to centrifugal force, thereby improving the stability of the connection between the mounting ring 4 and the splitting roller 3.

[0031] See also Figures 2-3 A counterweight 46 is fixedly provided at one end of the split roller 3 away from the gripping plate 43. The counterweight 46 can roughly balance the weight on both sides of the split roller 3 to prevent the gripping plate 43 of the split roller 3 from being too heavy and causing the split roller 3 to rotate unsteadily.

[0032] See also Figure 1 , Figure 2 and Figure 4 The machine body 1 is provided with an adjusting mechanism for controlling the spacing between the splitting roller 3 and the coil on the carrying roller 2. The adjusting mechanism includes a rotating rod 5 rotatably arranged at both ends of the machine body 1, and two groups of connecting plates 51 fixedly arranged on the outer walls of both ends of the rotating rod 5. The splitting roller 3 is rotatably arranged between two adjacent groups of connecting plates 51. A connecting rod 52 is fixedly arranged in the middle of the outer wall of the rotating rod 5. A cylinder 53 is rotatably arranged between one end of the connecting rod 52 and the bottom of the machine body 1. The connecting plate 51 can connect the rotating rod 5 and the splitting roller 3, and the connecting plate 51 and the connecting rod 52 can rotate with the rotating rod 5. The connecting rod 52 can connect the rotating rod 5 and the cylinder 53.

[0033] After the cylinder 53 is extended and retracted, it will drive the rotating rod 5, the connecting plate 51 and the dividing roller 3 and other components to rotate around the axis of the rotating rod 5 through the connection of the connecting rod 52, so as to control the distance between the dividing roller 3 and the coil on the carrying roller 2, so as to facilitate the slitting machine to slit PET coils of different thickness specifications.

[0034] Working principle: When in use, people can install the PET coil on the outside of the unwinding roller 11, and then connect one end of the coil through the guide roller 13 and the carrying roller 2 to the outside of the winding roller 12. At this time, people can control the extension and contraction of the cylinder 53 according to the thickness of the coil, and drive the rotating rod 5, the connecting plate 51 and the dividing roller 3 and other components to rotate around the axis of the rotating rod 5, so that the dividing knife 41 on the rotating outer side of the dividing roller 3 can abut on the coil, and then the external motor of the dividing roller 3 can be driven to drive the rotating dividing knife 41 to divide the coil on the carrying roller 2. At this time, the external motor of the winding roller 12 will drive the winding roller 12 to rotate and rewind the divided coil;

[0035] When it is necessary to adjust the splitting width of the coil material, people can hold the grip plate 43 and pull it strongly outward to the splitting roller 3, so that the pin rod 44 is pulled into the tension pin hole, thereby detaching the splitting assembly from the fixation. Then people can slide the splitting assembly such as the mounting ring 4 on the splitting roller 3. After the components such as the mounting ring 4 enter the required position, people can press the grip plate 43 strongly toward the splitting roller 3 side, so that the pin rod 44 is inserted into the corresponding pin hole to fix the moved splitting assembly such as the mounting ring 4. At the same time, the suction cup 45 will adsorb the splitting roller 3 to improve the connection stability between the mounting ring 4 and the splitting roller 3.

[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
