Technical Field

[0001] The present disclosure relates to the technical field of tape casting machines, and in particular to a slitting device for tape casting machines. Background Art

[0002] Cast film machine refers to special equipment used for making cast film. The demand for the use of film in various industries is constantly increasing. It is widely used in food and medicine and other fields, such as beverage packaging, quick-frozen food packaging, steamed food packaging, fast food packaging, etc. These products have brought great convenience to people's lives. In the processing and production process of film, it is cut into a certain width according to demand for subsequent processing and use. In the prior art, since the cutting components are connected by passing through the tool holder shaft, when the number of cutting components needs to be adjusted, the tool holder shaft needs to be removed as a whole, and the tool holder shaft needs to be reinstalled after installation or disassembly. After multiple installation and disassembly operations, it is easy to cause wear of the tool holder shaft, and the installation and disassembly process is cumbersome and complicated, which affects production efficiency.

[0032] Reference Figure 1-Figure 4 A slitting device for a film casting machine comprises a frame 1, a conveying roller 2 arranged between the frames 1 for conveying materials, a knife frame shaft 3 installed between the frames 1 and located above the conveying roller 2, and a plurality of cutting components 4 arranged on the knife frame shaft 3, wherein the cutting components 4 are movably connected to the knife frame shaft 3, and the cutting components 4 are used for slitting and cutting films of various sizes;

[0033] The cutting assembly 4 includes a clamping component 41, an extension plate 42, an adjusting component 43 and a blade 44. The clamping component 41 includes a left clamping plate 411, a right clamping plate 412, a rotating shaft 413 and a bolt 414. The left clamping plate 411 is rotatably arranged on the rotating shaft so that the left clamping plate 411 can rotate around the rotating shaft 413 and move closer to or away from the right clamping plate. A through hole 4112 is arranged on the other end of the left clamping plate 411, and a screw hole 4122 is arranged on the other end of the right clamping plate 412. By extending one end of the bolt 414 through the through hole 4112 to the screw hole 4122, the bolt 414 can be screwed. The cutting assembly 4 is connected by a thread, so that the cutting assembly 4 can be installed on the knife holder shaft 3, and the bolt 414 fixes it, thereby ensuring the stability of the cutting assembly 4 during the slitting process, so as to improve the production quality of the film, and can also quickly and conveniently adjust the number and position of the cutting assembly 4, and the structure is simple, while effectively improving the production efficiency. A through first notch 421 is provided in the middle of the extension plate 42, and the extension plate 42 is fixed to the side of the right clamping plate 412 away from the left clamping plate 411, and a through second notch 441 is provided on the upper part of the blade 44, and the blade 44 is movably connected to the extension plate 42;

[0034] The adjusting component 43 is arranged between the extension plate 42 and the blade 44. The adjusting component 43 includes a cylindrical gear 431, a rotating rod 432 and a connecting rod 433 arranged on the extension plate 42. One end of the cylindrical gear 431 extends to the outside of the extension plate 42 and is equipped with a knob 4311. The operator can drive the cylindrical gear 431 to rotate by rotating the knob 4311, which is convenient for the operator to quickly adjust and improves the performance of the cutting assembly 4. One end of the rotating rod 432 is provided with a large disk wheel 4321, and the other end passes through the second notch 441 and is movably connected to the blade 44, and is meshed with the cylindrical gear 431 through the teeth provided on the large disk wheel 4321, so that the blade 44 is more stable during the movement, and the service life of the cutting assembly 4 is longer and the efficiency is higher. One end of the connecting rod 433 passes through the second notch 441 and is fixedly connected to the blade 44, and the other end passes through the first notch 421 and is movably connected to the extension plate 42.

[0035] The rotating rod 432 and the connecting rod 433 are linked by the connecting shaft. By turning the knob 4311, the blade 44 can move vertically on the extension plate 42. The adjustment component 43 is arranged to facilitate the operator to accurately adjust the distance between the blade 44 and the conveying roller 2, so that the blade 44 can be adjusted accordingly according to the requirements of the production film size, thereby expanding the production application range of the slitting device, meeting production needs, effectively improving production efficiency, and being more practical. When the remaining cutting components 4 are not working for a long time, they do not need to be disassembled. The blade 44 can be moved parallel to the extension plate 42 by turning the knob 4311, thereby reducing the wear rate of the blade 44 and extending its service life.

[0036] The blade 44 can be moved vertically on the extension plate 42 because the adjustment component 43 is provided between the extension plate 42 and the blade 44. The adjustment component 43 can be provided between the extension plate 42 and the blade 44 because the adjustment component 43 is provided between the extension plate 42 and the blade 44. Therefore, the rotation rod 432 and the connecting rod 433 are linked through the connecting shaft by rotating the knob 4311, so that the blade 44 can be adjusted accordingly according to the production film size requirements, thereby expanding the production application range of the slitting device and meeting the production needs. At the same time, the wear rate of the blade 44 is reduced and the service life is longer. This design is not only simple and ingenious, but also fast and convenient, thereby effectively improving the efficiency of film production and the practicality of the slitting device.

[0037] In one embodiment, referring to Figure 1-Figure 4The adjusting component 43 also includes a fastener 434, which is located at one end where the rotating rod 432 and the connecting rod 433 are movably connected to the blade 44. By extending one end of the fastener 434 through the second slot 441 to the rotating rod 432 and the connecting rod 433 for movably connecting, the blade 44 can be installed or removed from the extension plate 42, thereby achieving fast and convenient replacement of the worn blade 44, reducing production costs and effectively improving production efficiency.

[0038] In one embodiment, referring to Figure 1-Figure 2 , rotating plates 31 are hinged on both sides of the frame 1, and the tool holder shaft 3 is arranged between the two sets of rotating plates 31. The arrangement of the rotating plates 31 enables the tool holder shaft 3 to rotate synchronously according to the rotation direction of the rotating plates 31. When it is necessary to move the cutting assembly 4 or disassemble the conveying roller 2, the rotating plates 31 can be rotated so that the tool holder shaft 3 can be rotated out of the frame 1, which is convenient for the operator to adjust the position of the cutting assembly 4 and disassemble the conveying roller 2, thereby improving the performance of the slitting device. A ruler 32 is arranged on the tool holder shaft 3, which is beneficial for the operator to accurately adjust the installation position of the cutting assembly 4, and the operation is more convenient.
