Technical Field

[0001] This utility model relates to the field of composite film processing technology, specifically to a position-adjustable BOPP composite film slitting device. Background Technology

[0002] BOPP (biaxially oriented polypropylene) composite film has wide applications in the packaging industry. In actual production, BOPP composite film needs to be slit according to different product specifications, requiring the use of slitting equipment.

[0003] In existing composite film slitting equipment, the position of most slitting mechanisms is fixed during use. When it is necessary to change the slitting width or adapt to raw material rolls of different diameters, each slitting blade needs to be manually adjusted individually. This involves many steps, and manual adjustment by operators may easily introduce errors due to difficulty in controlling the adjustment force, which will affect the slitting accuracy of the composite film. If it is difficult to make flexible and stable adjustments to the slitting mechanism, the equipment will have poor versatility, which will affect the slitting accuracy and efficiency of the composite film processing slitting equipment. Optimization and improvement are needed. Utility Model Content

[0016] 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.

[0017] 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.

[0018] like Figure 1 - Figure 5 As shown, this application provides a position-adjustable BOPP composite film slitting device, including: a slitting frame 1, a film roller 2 rotatably connected to one side of the top of the slitting frame 1, and a guide roller 3 rotatably connected to the middle of the inner side of the slitting frame 1; a slitting adjustment assembly including a sliding guide bar 8, the sliding guide bar 8 being fixedly connected to the bottom inner side of the slitting frame 1, a grooved guide frame 10 connected to one side of the sliding guide bar 8, and a slidable sliding blade 11 connected to the top of the grooved guide frame 10; the slitting adjustment assembly is used for size adjustment during composite film slitting; specifically, as shown... Figure 1 As shown, a laminating table 4 is fixedly connected to one side of the slitting frame 1, and a winding roller 5 is rotatably connected to the top of the laminating table 4. The slitting BOPP composite film is transported along the inclined surface of the laminating table 4 and is wound up and stored by the winding roller 5.

[0019] Specifically, such as Figure 1 As shown, an adjustment limiting groove 6 is provided on one side of the top wall of the slitting frame 1. The adjustment limiting groove 6 is used to restrict the longitudinal movement of the slitting blade 11, so that the slitting blade 11 can be adjusted to a certain extent inside the adjustment limiting groove 6.

[0020] Specifically, such as Figure 3As shown, a telescopic cylinder 7 is fixedly installed on the inner bottom of the slitting frame 1. A slide rod 9 that is slidably connected to the sliding guide bar 8 is fixedly connected to one side of the telescopic cylinder 7. The telescopic cylinder 7 drives the slide rod 9 to slide inside the sliding guide bar 8, which facilitates stable adjustment of the position of the grooved guide frame 10.

[0021] Specifically, such as Figure 3 As shown, the grooved guide frame 10 is fixedly connected to one side of the slide rod 9. The grooved guide frame 10 is divided into five connecting strips, each with a different angle. The purpose is to restrict the slitting blade 11 from making synchronous longitudinal position adjustments when the grooved guide frame 10 moves laterally. The bottom end of the slitting blade 11 is slidably connected to the grooved guide frame 10, and the slider at the bottom end of the slitting blade 11 also changes angle according to the corresponding connecting strip to ensure that the slitting blade 11 is always perpendicular to the adjusting limit groove 6.

[0022] Specifically, such as Figure 3 and Figure 4 As shown, the slitting blades 11 are connected by an elastic connector 14. A pulley 15 is fixedly installed on the inner side of the slitting blades 11. A guide rod 13 that is slidably connected to the slitting blades 11 is fixedly connected to one end of the inner side of the adjusting limiting groove 6. A limiting strip 12 that is adapted to the pulley 15 is fixedly connected to the bottom end of the inner side of the adjusting limiting groove 6. The slitting blades 11 are connected to the elastic connector 14 and slide through the guide rod 13. While limiting a certain position, the squeezing force of the elastic connector 14 also achieves a certain protective effect, making the slitting blades 11 less prone to damage during adjustment. The pulley 15 on the inner side of the slitting blades 11 rolls on the limiting strip 12. While reaching the limit, it also reduces friction and improves the smoothness and flexibility of the slitting blades 11 during transfer.

[0023] The pressing protection assembly includes a slide frame 16, which is fixedly connected to one side of the top of the slitting frame 1. A sliding pressure plate 18 is slidably connected to the inner side of the slide frame 16. A bonding pressure roller 20 is provided at the bottom end of the sliding pressure plate 18. The pressing protection assembly is used for limiting pressing protection during composite film slitting.

[0024] Specifically, such as Figure 5 As shown, a telescopic cylinder 17 is fixedly connected to the top of the sliding frame 16, and a sliding pressure plate 18 is fixedly connected to the bottom of the telescopic cylinder 17. A snap-fit ​​positioning rod 19 is slidably connected to the inner side of the sliding pressure plate 18, and a bonding roller 20 is fixedly connected to the bottom of the snap-fit ​​positioning rod 19. The telescopic cylinder 17 drives the sliding pressure plate 18 to slide and adjust inside the sliding frame 16, and then drives the bonding roller 20 to press down and bond the BOPP composite film. The bonding roller 20 has a smooth outer surface to reduce the friction generated during the bonding of the BOPP composite film. It cooperates with the guide roller 3 to limit the movement, ensuring the stability of the BOPP composite film during transmission and ensuring the slitting efficiency.

[0025] In this embodiment: When slitting the composite film, the grooved guide frame 10 is slidably adjusted by the telescopic cylinder 7. The grooved guide frame 10 is set at different angles. The lateral adjustment of the grooved guide frame 10 can drive the slitting blade 11 to be longitudinally adjusted inside the adjustment limiting groove 6. The positions of different slitting blades 11 can be adjusted synchronously and stably to adapt to the slitting requirements of BOPP composite films of different widths. When slitting the BOPP composite film, the guide roller 3 is set to reverse the direction of the film so that it fits the slitting blade 11 better. Then, the telescopically adjustable sliding pressure plate 18 is used to flexibly press and limit the transmission of the BOPP composite film, making the slitting more stable and ensuring the processing efficiency of the equipment.

[0026] Specifically, when slitting BOPP composite film, the film is first placed on the film roller 2, and then one end of the film passes through the bottom of the guide roller 3 for guidance and transmission. Before slitting, the width of the BOPP composite film needs to be adjusted. At this time, the grooved guide frame 10 is slidably adjusted by the telescopic cylinder 7. The grooved guide frame 10 has multiple adjustment channels inside according to the number of slitting blades 11, and the angles of these channels are different. The purpose is to ensure that the longitudinal adjustment distance of the slitting blades 11 is the same when the grooved guide frame 10 moves laterally. When the grooved guide frame 10 is adjusted laterally, the inner side of the slitting blades 11 is guided by the guide rod 13 and the limiting strip 1. The setting of 2 provides longitudinal movement limit, which can drive the slitting blade 11 to adjust the stability of longitudinal adjustment inside the adjustment limit groove 6. The position of different slitting blades 11 is adjusted synchronously and stably to adapt to the slitting requirements of BOPP composite film of different widths. While slitting the BOPP composite film, a telescopic and adjustable sliding pressure plate 18 is set to flexibly press and limit the transmission position of the BOPP composite film close to the guide roller 3, making the slitting more stable and ensuring the processing efficiency of the equipment. Then, after adjustment, the BOPP composite film slid by the slitting blade 11 is guided along the laminating table 4 and wound up and stored by the winding roller 5.
