Description

Technical Field

[0001] This invention relates to the field of filter rod forming technology, and more specifically to a process method for reducing suction resistance in a filter rod forming machine. Background Technology

[0002] The filter rod forming process is an important part of the cigarette manufacturing process. Its main task is to loosen the cellulose acetate tow in the horizontal and vertical directions, then spray plasticizer on the evenly loosened tow belt, convey it to the forming cigarette gun, wrap it with forming paper, and form, glue, and cut it according to the process requirements to finally form a filter rod that meets the process requirements.

[0003] However, existing filter rod forming processes result in large fluctuations in suction resistance and serious exceedances of SD values ​​during production, leading to high scrap rates and severely impacting normal production. Therefore, there is a need for a filter rod forming machine process to reduce suction resistance. Summary of the Invention

[0004] In view of the above-mentioned shortcomings in the existing technology, the present invention provides a process method for reducing suction resistance in a filter rod forming machine, which solves the problem that the existing filter rod forming process has large fluctuations in suction resistance and serious exceedance of SD value, resulting in high scrap rate and seriously affecting normal production.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A process for reducing suction resistance in a filter rod forming machine includes the following steps:

[0007] S1. Fiber bundle extraction: The fiber bundle is unpacked and aligned with the lifting roller for winding, and then carried into the first-stage air opener by the lifting roller;

[0008] S2, First air opening: The first air opening evenly blows the filament bundle apart, eliminating folds and twists in the filament bundle. The width of the first air opening is 200mm.

[0009] S3, Second Air Opening: The second air opening further stabilizes the position of the filament bundle, allowing the filament bundle to spread laterally and smoothly enter the opening roller group. The width of the second air opening is 240mm.

[0010] S4. Roller opening: When the filament belt passes through the opening roller group, adjust the opening ratio of the first opening roller to the second opening roller to 1:1.28 and the load ratio to 50%:50% to achieve the purpose of laterally opening the filament belt.

[0011] S5, Third Air Loosening: The third-stage air loosening causes the filament bundle to expand laterally, with a width of 260mm.

[0012] S6. Apply glycerin: The filament bundle enters the spraying chamber, and glycerin is evenly sprayed onto the surface of the filament bundle.

[0013] S7. Rolling and forming: Apply overlap glue and centerline glue to the surface of the forming paper. Under the drive of the conveyor belt, the forming paper wraps the filament bundle to form a uniform linear cylinder.

[0014] S8. Filter rod loading: The filter rods are cut into strips and loaded onto trays after passing through the cutter disc and the smoke separator.

[0015] Furthermore, in step 4, the fixed tooth width of both the first and second opening rollers is 0.90 mm, and the tooth depth is 0.65 mm.

[0016] Furthermore, in step 4, the diameter difference between the first opening roller and the second opening roller is 0.05 mm.

[0017] Furthermore, in step 6, the glycerin is sprayed at an angle of 80 degrees.

[0018] Furthermore, the crimp of the filament bundle is 2.5.

[0019] Furthermore, the number of curls in the filament bundle is 25.

[0020] The beneficial effects of this invention are:
