Description

Technical Field

[0001] This application relates to the field of film slitting technology, specifically to a packaging film slitting device. Background Technology

[0002] "Packaging film" is a general term encompassing a variety of film materials used for wrapping and protecting goods. Common packaging film materials typically include polyethylene, polypropylene, polyvinyl chloride, and composite films, all of which possess good tensile strength and toughness.

[0003] A search revealed, for example, a patent with publication number CN211225754U, which specifically discloses a cutting machine for cutting films. This patent uses two or more sets of pressure rollers and a moving clamp assembly to reduce wrinkles during film cutting and reduce cutting errors.

[0004] The device described above can only cut once at a time during use, and cannot cut multiple films simultaneously. This makes it difficult to adjust the distance between the cutting blades according to the required situation during the slitting process, and it cannot cut films of different sizes.

[0005] However, conventional slitting devices typically require replacing the entire slitting blade or disassembling the blade separately and readjusting its position when faced with films of different sizes. This makes it difficult to control the slitting size each time, and is time-consuming and labor-intensive, affecting slitting efficiency. Therefore, it is necessary to provide a packaging film slitting device to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0032] like Figures 1-2As shown, this application provides a packaging film slitting device, including a support frame 5. A transmission mechanism 1 is provided at the upper end of the support frame 5. The transmission mechanism 1 is used to transport and transmit the packaging film from other workstations to the slitting device. The transmission mechanism 1 has two sets of upright plates 11 fixedly installed on both sides of the upper end of the support frame 5. A transmission roller 12 is rotatably connected between the two sets of upright plates 11. Multiple sets of transmission shafts 13 are fixedly installed on the transmission roller 12. A drive device is driven to one side of the transmission roller 12. The drive device is used to drive the transmission roller 12 to rotate.

[0033] In this application, the drive device consists of a sprocket, a chain, and a motor as in the prior art. Typically, a sprocket is installed on the side end of the guide roller 12 and the output end of the motor, and then the drive is transmitted through the chain. Therefore, starting the motor can drive the guide roller 12 to rotate.

[0034] Meanwhile, a mounting bracket 14 is fixedly installed on one side of the upright plate 11. Multiple sets of conveying rollers 15 are rotatably connected between the mounting brackets 14. It should be noted that the height of these multiple sets of conveying rollers 15 is higher than the lowest end of the transmission shaft 13, thus ensuring the tension of the film during the transmission process.

[0035] Furthermore, a fixing plate 16 is fixedly installed on the inner side of the upper end of the upright plate 11. The fixing plate 16 is inclined downwards, and a pressure roller 17 is rotatably connected between the fixing plates 16. The pressure roller 17 presses the upper end of the film to improve the transmission stability.

[0036] like Figures 2-3 As shown, a cutting mechanism 2 is also provided on the other side of the upright plate 11. The cutting mechanism 2 is used to cut the film transmitted by the transmission mechanism 1. The cutting mechanism 2 has a support plate 21 fixedly installed on the outside of the two sets of upright plates 11. The upper end of the two sets of support plates 21 is fixedly installed with an mounting plate 22. The mounting plate 22 has multiple sets of threaded holes 23, and bolts 27 are threadedly connected in the multiple sets of threaded holes 23.

[0037] Meanwhile, the upper end of the bolt 27 is rotatably connected to a blade clip 25, and a cutter 26 is fixedly installed inside the blade clip 25. Therefore, by rotating the bolt 27, the blade clip 25 can be moved up and down, thus adjusting the position and height of the cutter 26.

[0038] Furthermore, multiple sets of compression springs 28 are fixedly installed between the tool holder 25 and the mounting plate 22. The compression springs 28 are sleeved on the outside of the bolt 27. In this application, the number of compression springs 28 is the same as the number of threaded holes 23. The compression springs 28 are used to improve the engagement degree between the bolt 27 and the threaded holes 23.

[0039] To prevent the tool holder 25 from wobbling, a pin 4 is fixedly installed at the bottom of the tool holder 25. At the same time, a movable hole 24 is provided on the mounting plate 22. The movable hole 24 is located to the side of the threaded hole 23. The pin 4 is movably connected in the movable hole 24. Therefore, the stability of the tool holder 25 is ensured by the pin 4.

[0040] It should be noted that the initial position of the cutter 26 is below the bottom of the guide roller 12, and it can be adjusted according to the requirements when needed.

[0041] like Figure 1 As shown, two sets of extension frames 3 are fixedly installed on the side of the upright plate 11 near the slitting mechanism 2. A first bearing seat 31 is fixedly installed on the upper end of each of the two sets of extension frames 3. A first take-up roller 32 is fixedly installed between the first bearing seats 31. The slitting film can be wound up by the first take-up roller 32.

[0042] In order to separate and wind up films of different sizes, in this application, the extension frame 3 is provided in an L-shape, and a second bearing seat 33 is fixedly installed at the upper end of the two sets of extension frames 3. A second take-up roller 34 is fixedly installed between the second bearing seats 33, and the second take-up roller 34 is located above the first take-up roller 32.

[0043] It should be noted that in this application, the dimensions between the multiple sets of cutters 26 are the fixed dimensions required for film slitting, and the dimensions have been correctly adjusted during installation.

[0044] In summary: When faced with films of different sizes, the operator selects the appropriate cutter 26 according to the requirements, then tightens the bolt 27 to adjust the cutter 26 upwards so that it is higher than the bottom of the guide roller 12. The film ends are then cut and wound onto the first take-up roller 32 and the second take-up roller 34 respectively. Finally, the device is started normally to complete the cutting operation. Therefore, it is not necessary to replace the entire cutter 26 each time, or to disassemble and readjust the cutter 26 individually, ensuring the correct cutting size each time. This saves time and effort and improves cutting efficiency.

[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
