Description

Technical Field

[0001] This utility model relates to the field of fireproof composite film slitting technology, and in particular to a slitting device for fireproof composite films. Background Technology

[0002] Fire-resistant composite membrane is a functional composite material with fire-retardant and heat-insulating properties. It is usually composed of multiple layers of materials with different properties and is widely used in construction, industry, transportation and other fields. Since the width of fire-resistant composite membrane used in different fields is different, it is necessary to cut the fire-resistant composite membrane into appropriate widths during the production process.

[0003] The fire-resistant composite membrane slitting device drives the rotating shaft to rotate synchronously through a drive mechanism, causing the cutter to make a circular motion around the rotating shaft as the center, and laterally cuts the conveyed composite membrane to slit it into the required width. However, in the process of using the fire-resistant composite membrane slitting device, since the traditional structure is mostly fixed welding or bolt connection, the spacing of the cutter needs to be adjusted by disassembling the cutter and repositioning the bolt holes, which makes the adjustment of the fire-resistant composite membrane slitting device take too much time. Based on the above problems, this application proposes a slitting device for fire-resistant composite membranes. Utility Model Content

Inside the bracket 1, a limiting protrusion is fixedly installed on the surface of the mounting column 4, and a limiting groove is opened inside the internal threaded sleeve 6. The limiting groove and the limiting protrusion are slidably connected. When it is necessary to cut the fireproof composite film into different widths, the internal threaded sleeve 6 is loosened, and the upper locking plate 5 and the lower locking plate 7 are pulled apart. The mounting sliding sleeve 3 drives the mounting vertical plate 9 to move through the mounting horizontal plate 8, so that the mounting vertical plate 9 drives the connecting component and the mounting shaft 14 to move, so that the mounting shaft 14 drives the cutter 15 to move through the bolt. Adjust the distance between the cutters 15. After the adjustment is completed, push the upper locking plate 5 into the interior of the lower locking plate 7, and fix the upper locking plate 5 with the internal threaded sleeve 6. The upper locking plate 5 fixes the mounting column 4 through the limiting protrusion and the limiting groove, so that the mounting sliding sleeve 3 fixes the position of the mounting shaft 14 through the mounting horizontal plate 8 and the mounting vertical plate 9, thereby fixing the position of the cutter 15. The fireproof composite film is cut into different widths through the knife groove on the surface of the cutter 15 and the support roller 16.

[0022] Specifically, the drive assembly includes a drive motor 20 fixedly mounted on the rear side of the mounting bracket 1. A drive shaft 26 is fixedly mounted at the output end of the drive motor 20. The drive shaft 26 is slidably connected to the rotating sleeve 10. An upper sprocket 23 is fixedly mounted at the front end of the drive shaft 26. A drive chain 22 is meshed on the surface of the upper sprocket 23.

The connecting shaft 19 is rotatably mounted inside the mounting bracket 1. An upper gear 18 is fixedly mounted on the surface of the upper gear 18, and a lower gear 17 is meshed on the surface of the upper gear 18. The lower gear 17 is fixedly mounted on the front end of the support roller 16. A connecting groove is opened on the surface of the drive shaft 26. A connecting slider is fixedly mounted inside the rotating sleeve 10 and is slidably connected to the connecting groove. A protective shell 25 is fixedly mounted on the front side of the mounting bracket 1. The connecting assembly includes a rotating sleeve 10 rotatably mounted inside the mounting vertical plate 9.

There is a transmission chain 12, with a lower sprocket 13 meshing inside the transmission chain 12. The mounting bracket 1 is fixedly installed at the rear end of the mounting shaft 14. The output end of the drive motor 20 drives the transmission shaft 26 to rotate, so that the transmission shaft 26 drives the rotating sleeve 10 to rotate inside the mounting vertical plate 9 through the connecting groove and the connecting slider. The rotating sleeve 10 drives the upper sprocket 11 to rotate, so that the upper sprocket 11 drives the lower sprocket 13 to rotate through the transmission chain 12, and the lower sprocket 13 drives the mounting shaft 14 to rotate on the mounting vertical plate 9. The plate 9 rotates internally, and the mounting shaft 14 drives the cutter 15 to rotate via bolts. At the same time, the transmission shaft 26 drives the upper sprocket 23 to rotate, so that the upper sprocket 23 drives the lower sprocket 21 to rotate via the transmission chain 22. The lower sprocket 21 drives the connecting shaft 19 to rotate inside the mounting bracket 1, and drives the upper gear 18 to rotate via the connecting shaft 19. The upper gear 18 drives the lower gear 17, which is meshed with it, to rotate, so that the lower gear 17 drives the support roller 16 to rotate, so that the cutter 15 cuts the fireproof composite film.

[0023] Specifically, a protective housing 24 is fixedly installed on the rear side of the mounting plate 9. The upper sprocket 11, the transmission chain 12, and the lower sprocket 13 are all located inside the protective housing 24. The protective housing 24 facilitates the protection of the upper sprocket 11, the transmission chain 12, and the lower sprocket 13, preventing them from being directly damaged by collisions. It also prevents dust from adhering to the surfaces of the upper sprocket 11, the transmission chain 12, and the lower sprocket 13.

[0024] In use: When the fireproof composite film needs to be cut into different widths, loosen the internal thread sleeve 6, pull the upper locking plate 5 to separate from the lower locking plate 7, pull the mounting sleeve 3 to slide on the surface of the mounting slide rail 2, so that the mounting sleeve 3 drives the mounting horizontal plate 8 to move, and the mounting horizontal plate 8 drives the mounting vertical plate 9 to move, so that the mounting vertical plate 9 drives the rotating sleeve 10 and the mounting shaft 14 to move, so that the mounting shaft 14 and the rotating sleeve 10 drive the upper sprocket 11 and the lower sprocket 13 to move respectively, and the upper sprocket 11 and the lower sprocket 13 drive the transmission chain 12 to move, so that the mounting shaft 14 drives the cutter 15 to move through the bolt. Move and adjust the distance between the cutters 15. After adjustment, push the upper locking plate 5 into the lower locking plate 7 and tighten the inner threaded sleeve 6 on the surface of the mounting column 4, so that the inner threaded sleeve 6 fixes the upper locking plate 5. The upper locking plate 5 fixes the mounting column 4 through the limiting protrusion and limiting groove, so that the mounting column 4 fixes the position of the mounting sliding sleeve 3. This allows the mounting horizontal plate 8 to fix the position of the mounting shaft 14 through the mounting vertical plate 9, and the mounting shaft 14 to fix the position of the cutter 15. The fireproof composite film is cut into different widths through the knife grooves on the surfaces of the cutter 15 and the support roller 16.
