Description

Technical Field

[0001] This utility model relates to the technical field of film slitting equipment, specifically to a slitting device for plastic film rolls. Background Technology

[0002] A film slitting device is a specialized piece of equipment used to cut wide films to the required width. Film slitting devices are widely used in packaging, electronics, solar energy and other fields. In the packaging industry, film slitting devices can cut large rolls of film into rolls suitable for different packaging specifications. With the transformation and upgrading of the manufacturing industry and the vigorous development of the new materials industry, film slitting devices are developing towards automation, intelligence and greening.

[0003] Existing film slitting devices lack adjustable slitting and cutting distances. For example, a film slitting machine disclosed in application number CN202010749243.0 does not have this feature, and its cutting width is typically fixed. This necessitates replacing the entire cutting assembly or adjusting the entire device when processing films of different widths, reducing its flexibility. For production lines requiring frequent changes in cutting width, this limitation severely impacts production efficiency. As the types and variations of film materials increase, the requirements for cutting accuracy also rise. Slitting devices without adjustable slitting and cutting distances often struggle to adapt to the cutting needs of films of different materials and thicknesses, potentially leading to unstable cutting quality, even scrap, and increased production costs. Furthermore, the lack of adjustable slitting and cutting distances necessitates tedious manual adjustments or disassembly for operators when changing cutting widths.

[0004] Therefore, it is necessary to invent a slitting device for plastic film rolls to solve the above problems. Utility Model Content

[0025] A top seat 6 is fixedly installed on the top of the movable frame structure 5. A placement seat 7 is placed in the middle of the top seat 6.

The cutter 903 is installed on the output end of the telescopic adjustment rod 902 through a detachable part 904.

[0026] The working principle of this practical application is as follows:

[0027] Refer to the instruction manual appendix Figure 1-5For this type of plastic film roll slitting device, the plastic film roll to be slitted is first placed on the roll body 4 on the cutting table 3, ensuring the film is flat and fixed. Based on the required slitting width and spacing, the controller 9 and its related components, such as the telescopic adjustment rod 902 and the cutter 903, are adjusted. The position of the pressure plate 206 is also adjusted to press it firmly onto the film, ensuring the stability of the film during cutting. The power is then connected, and the device is started. At this time, the first motor 204 begins to work. During the cutting process, the first motor 204 drives the reciprocating screw 202 to rotate. The movement of the movable seat 207 on the reciprocating screw 202 causes the film to... The movable frame structure 5 moves back and forth above the side platform 2, which also causes the frame rod 8 and the cutting blade 903 used for slitting to move back and forth on the roll body 4 of the cutting table 3 to achieve the purpose of slitting and cutting. The cutting parameters, such as cutting speed and cutting depth, are set on the controller 9, and the cutting program is started. The controller 9 controls the driver 901 to drive the telescopic adjustment rod 902 to extend and retract, which in turn drives the cutting blade 903 to cut the film. During the cutting process, the cutting situation of the film is observed. If necessary, the cutting parameters can be adjusted at any time. After the cutting is completed, the power is turned off and the device is stopped. The cut film strips are removed from the cutting table 3 for collection and sorting.

[0028] According to the preset cutting parameters, the controller 9 controls the driver 901 to drive the telescopic adjustment rod 902 to extend and retract. The extension and retraction of the telescopic adjustment rod 902 drives the cutter 903 to cut the film, thus achieving slitting. The cutting groove design on the slitting table 301 allows the cutter 903 to accurately cut the film according to the preset width and spacing. After cutting, the cut film strips are collected and sorted by manual or automatic collection devices. This plastic film roll slitting device achieves efficient and accurate slitting and cutting of plastic film through precise drive and transmission mechanisms, pressing and positioning mechanisms, cutting and slitting mechanisms, and collection and sorting mechanisms.
