KLM-ZL-2 Automatic Suppository Filling and Sealing Machine
Main Application: High-speed, precise filling and sealing of suppositories for medical and pharmaceutical uses.
The full-automatic suppositories production unit integrates PLC for comprehensive control and pneumatic mode for power. Merging advanced foreign technology with domestic realities, it features a novel design and user-friendly operation. This highly efficient and stable automatic suppository production unit leads in domestic technical content. During development, we prioritize user convenience, ensuring adjustable and precise operations. It can mold various shapes and specifications of suppositories using different packaging materials (PVC, PE, PVC/AL/PE Compound film), effectively eliminating defective products.
Working Principle:
The rolled plastic sheet material (PVC or PVC/PE) is positively pressed and blown into shape, then automatically enters the filling procedure. The drug fluid is evenly stirred and precisely dosed through a high-precision pump into multiple segments. It solidifies through multiple cryo-stereotypia stages, transitioning from fluid to solid. Finally, the suppositories undergo forming, sealing, batch numbering, and shearing to become the end product.
Instruction and Description
1) Operating Principle
1.1)Finalize the design:

, shearing numbers.
1.2)Filling Part:
The film material (PVC/PE) from the film release tray enters the forming area through the servo transmission and clamping mechanism, passing sequentially through the pre-heating mold, forming mold, and blowing mold for film formation.
The material PVC/PE (height 58-65mm, thickness 0.13-0.20mm, outer diameter 180-220mm, inner diameter 70-85mm) is loaded into the film release plate and tightened (Figure 3). The film is symmetrically fed through the film roller with the PE film layer as the adhesive layer. It undergoes compression molding, film separation, support, and servo conveying (Figure 4). For precise and easy operation, displacement positions can be adjusted via touch screen parameters, ensuring feeding accuracy below 0.02mm. The machine can be expanded to accommodate different molds, making replacement straightforward.
1.3) Cooling Part
The filled plug shells are continuously conveyed in an S-shaped serpentine through the film feeding wheel (Fig. 11) and enter the cooling tunnel (Fig. 12) for effective solidification.The cooling tunnel features an innovative S-shaped cooling channel with one precise temperature control point for dual-stage water cooling. This intelligent design allows you to conveniently adjust the cooling temperature to match the specific characteristics of the medicament, ensuring a flawless and burr-free finish on the suppositories.The cooling plate operates via a synchronous pulley motor transmission (Fig. 13), with speed adjustments made through the intuitive touch screen. For added protection, a photoelectric induction stop at the transition prevents the bolt shell from breaking. Notably, the charging part's shell does not contact any components during conveyance, preserving the pristine surface of the formed plug shell. Once cooled and solidified, the suppository progresses to the sealing, shearing, and coding station (Figure 14).
1.4)Seal and Print Code Section:
This station is composed of several high-precision devices: a servo film feeding device (Fig. 15), a heating batch number device (Fig. 16), a triangle dotted line device (Fig. 17), a driven film feeding device (Fig. 18), a pre-cutting film feeding device (Fig. 19), an upper trimming device, a shearing device (Figure 20), and an optional waste collection device (vacuum cleaner device).
The cooled plug shell transfers to the servo film feeding device via the transition wheel, then moves into the heating mold and batch number mold for coding. Codes can be tailored to various requirements and are easy to change. Next, the coded plug shells seamlessly enter the triangular dotted line device for lower edge trimming and are cut between the medicine grains, allowing each grain to be easily separated. Cut waste is collected in the lower waste slot. Subsequently, the plug shell advances to the driven film feeding device (adjustable through touch screen parameters for precise positioning) and upper trimming device for final shaping. The resultant waste is directed to the lower waste slot. The trimmed shell then moves to the pre-shearing film feeding device (precisely controlled by servo drive) to be sheared into the required number of particles, which can be adjusted to user specifications (e.g., 1-10 particles).
