ZL21 Filter Rods Making Machine – Cost-Efficient Domestic Filter Rod Forming Equipment For Small & Medium Tobacco Factories

Introduction to ZL21 Filter Rods Making Machine

The ZL21 filter rods making machine is a mature domestic filter rod forming unit, specially developed for small and medium-sized tobacco manufacturers with moderate filter output demand. The whole unit consists of two core modules: YL11 tow opening & plasticizer coating machine and YL21 filter rod forming cutter, completing tow unwinding, expansion, plasticizer spraying, rolling, paper wrapping and fixed-length cutting in one continuous workflow.

Different from high-speed imported KDF2 filter rod machines with high investment cost, ZL21 features compact footprint, low power consumption and affordable purchase & maintenance cost, supporting two mainstream raw materials: acetate tow and polypropylene tow, and can also produce grooved filter rods and water-soluble glue filter rods after simple modification.

It seamlessly connects downstream mini MK8, commercial MK9 and Protos70 automatic cigarette making machines, and can be matched with capsule filter cigarette manufacturing machine to produce burst-bead aroma capsule filter rods. Cooperated with full tobacco primary processing line and post-packaging equipment (GDX1/GDX2/HLP2 packers, YB59A film wrapper, YB69A carton machine), it builds a complete closed automatic cigarette production line from raw acetate tow & tobacco leaf to finished cartoned cigarettes.

All tow and filter contact components adopt anti-rust stainless steel, with closed dust-proof housing to prevent fiber scattering, stable enough for 24-hour continuous light industrial production.

• Key Advantages of ZL21 Filter Rods Making Machine For Tobacco Manufacturers

1. Ultra-Cost Performance For Small & Medium Filter Production ZL21 greatly lowers the threshold of filter rod independent production, with much lower procurement cost than imported KDF2 units. Its 8.5KW low power design cuts daily electricity expense, ideal for startup tobacco workshops, medium OEM factories and regional cigarette material suppliers with medium daily filter demand.
2. Dual Raw Material Compatibility, Diversified Filter Production Supports both acetate tow and polypropylene tow, and can produce grooved filter rods, ordinary plain filter rods and modified water-soluble glue filter rods after simple component adjustment, meeting multi-type filter product demands without purchasing multiple separate machines.
3. Seven-Vane Expansion Wheel, Precise Filter Size Control Equipped with seven-vane expansion & shrinkage tape wheel, effectively controls filter rod length, circumference and hardness errors. Finished filter rods meet high-speed tipping matching requirements of MK9 and Protos70 cigarette makers, avoiding tipping failure and defective cigarettes caused by irregular filter rods.
4. Simple Mechanical Structure, Easy Operation & Low Maintenance Modular split structure with fewer complex transmission parts; operators can master startup, parameter adjustment and daily cleaning within half a day without professional mechanical background. Centralized lubrication design reduces component abrasion; we stock full range domestic matching spare parts for ZL21 machine for fast global delivery and remote video technical guidance. Detachable feeding channels support quick cleaning of residual plasticizer and fiber scraps to prevent cross-contamination between different filter formulas.
5. Perfect Synchronous Docking With All MK Series & Protos Cigarette Makers Standard finished filter rod conveying outlet perfectly links mini MK8, commercial MK9 and Protos70 high-speed cigarette making machines, supporting real-time speed interlock for automatic filter feeding without manual transfer. Reserved docking interface for capsule filter inserting equipment enables integrated mass production of mint/fruit flavor burst bead capsule filter rods.
6. Compact Footprint, Suitable For Limited Workshop Space Compared with large KDF2 filter rod machines, ZL21 occupies far less workshop area, does not require oversized factory plant, convenient for layout reconstruction of old production workshops and new small factory construction.

Complete Production Workflow Matched With ZL21 Filter Rods Making Machine

1. Acetate or polypropylene tow raw material is loaded into ZL21 filter rods making machine for opening, plasticizer spraying, rolling, paper wrapping and fixed-length cutting into standard filter rods
2. Optional capsule filter inserting machine embeds aroma burst beads into filter rods for flavored capsule cigarettes
3. Finished filter rods are automatically conveyed to mini MK8 / commercial MK9 / Protos70 cigarette making machine
4. Uniform cut tobacco processed by tobacco primary line (steaming, separating, casing & flavoring, drying, storage silo, vibrating conveyor) enters cigarette maker feeding hopper
5. Cigarette machine completes tobacco rod rolling and filter tipping assembly
6. Finished tipped cigarettes flow into GDX1/GDX2/HLP2 cigarette packing machine for inner aluminum foil packet forming
7. Cigarette packets pass YB59A packing film machine for transparent cellophane wrapping with tear tape, then YB69A carton packing machine for strip carton loading and sealing for wholesale & export shipment
