Description

Technical Field

[0001] The utility model relates to the technical field of packaging film processing, and particularly relates to a multi-segment slitting device for packaging films. Background Technique

[0002] During the production of packaging films, it is usually necessary to cut the continuously produced film into coils of a specific length through a slitting process for easy packaging and use;

[0003] The slitting of packaging films is completed by a slitting device, which plays a crucial role in the production process of packaging films. The main function of the slitting device is to cut the continuous film into the required length on the production line;

[0004] During the slitting operation of the existing slitting device, if it is necessary to slit another specification of packaging film after slitting, the tool will be adjusted. The most common adjustment method is manual adjustment, and the operator needs to manually adjust the position of the tool according to the width to be cut. However, this adjustment method is not only inconvenient, but also there is a risk of being scratched, and it is impossible to quickly switch the slitting specification; at the same time, the slit packaging film will be wound up synchronously after slitting. However, in the existing winding operation, it is generally relied on the tension of the packaging film during transportation to ensure the compactness of the packaging film during winding. However, when the tension is insufficient and the winding facility lacks corresponding limiting measures, the wound packaging film will become loose, affecting the material taking of the film material;

[0005] Therefore, this application proposes a multi-segment slitting device for packaging films. Content of the Utility Model

[0028] Combined with Figures 1 - 5As shown, the utility model provides a packaging film multi-segment slitting device, including a base 1 and a shell 2, the shell 2 is fixedly installed on the top of the base 1, and a slitting assembly 8 is docked and installed inside the shell 2, and an adjustment assembly 3 is fixedly installed on the front of the shell 2, and the adjustment assembly 3 is used to drive the slitting assembly 8, a first support frame 5 is fixedly installed on one side of the top of the base 1, and a winding assembly 7 is docked and installed on the inner side of the first support frame 5, and a second mounting port 51 is provided on the first support frame 5, and an extended limiting assembly 9 is assembled in the second mounting port 51, and the limiting assembly 9 and the winding assembly 7 cooperate with each other;

[0029] During this period, the adjustment component 3 cooperates with the slitting component 8 to achieve real-time switching of the six groups of slitting rollers, and the six groups of guide rollers correspond to six different slitting specifications, which meets the slitting requirements of the packaging film, and there is no need to disassemble and adjust, and the switching is faster. The slit packaging film is rolled up through the winding component 7 to complete the separate collection. The limiting component 9 cooperates with the winding component 7, which not only ensures the winding of the separated packaging film, but also limits the rolled-up packaging film to prevent it from loosening, and can also make real-time buffering and giving way according to the increase in the winding amount to ensure the continuous winding of the packaging film.

[0030] The adjusting assembly 3 includes a mounting cavity 31, a tooth plate 32, a gear 33, and a cylinder 34; the cutting assembly 8 includes a first mounting plate 81, a second mounting plate 82, a cutting component 83, a separating component 84, and a docking shaft 85. The interior of the shell 2 is docked with the second mounting plate 82 and the first mounting plate 81 through the docking shaft 85, and the first mounting plate 81 and the second mounting plate 82 correspond to each other. Six groups of cutting components 83 are docked and installed between the first mounting plate 81 and the second mounting plate 82. Six groups of mounting ports 811 are provided on the first mounting plate 81 and the second mounting plate 82, and the separating component 84 installed and connected to the cutting component 83 is assembled in the mounting port 811.
