KLM-ZL-2 Automatic Suppository Filling and Sealing Machine
Main Application:
Our full-automatic suppository production unit, the pinnacle of modern engineering, harnesses a PLC-controlled system and pneumatic power to deliver unparalleled efficiency and stability. Marrying cutting-edge foreign technology with local expertise, this machine showcases a novel design that prioritizes user-friendly operation. It stands as a leader in domestic technical content, designed with the user in mind for adjustable and precise operations. This versatile machine can mold various suppository shapes and specifications using a range of packaging materials (PVC, PE, PVC/AL/PE Compound film), while effectively eliminating defective products.
Working Principle:
The process begins with the rolled plastic sheet material (PVC or PVC/PE) being positively pressed and blown into shape. It then automatically proceeds to the filling stage, where the drug fluid is evenly stirred and precisely dosed through a high-precision pump into multiple segments. This fluid solidifies through multiple cryo-stereotypia stages, transitioning seamlessly from fluid to solid. Finally, the suppositories undergo forming, sealing, batch numbering, and shearing to emerge as the final product.

1.2)Filling part:
The film material (PVC/PE) from the film release tray enters the forming area via the servo transmission and clamping mechanism. It then passes through the pre-heating mold -> forming mold -> blowing mold -> blowing film forming.
The PVC/PE material (height 58-65mm, thickness 0.13-0.20mm, with an outer diameter of 180-220mm and inner diameter of 70-85mm) is placed into the film release plate and secured by the tightening mechanism (as shown in Figure 3). When two printed sheets are placed on the film tray, they enter symmetrically via the film roller, with the PE film layer serving as the adhesive layer. The sheet moves through compression molding, film separation, support, and servo conveying mechanism (Figure 4). For accurate film feeding and ease of operation, the displacement position can be adjusted via the touch screen, ensuring feeding accuracy of less than 0.02mm. The machine can be expanded to accommodate 1 Duckbill type with a head spacing of 26mm or extended to 2 bullet/torpedo types with the same spacing by simply replacing the mold, which is designed for easy replacement. The sheet then enters the preheating, heating, and forming mold device (Figure 5), with temperature precisely adjustable via the touch screen. After the blowing mold device (Figure 6), the suppository is formed. It then moves to the filling station through the film guide device, with the operation screen located in the forming part (Figure 7) for user convenience. A three-level management password system is set up for efficient management.
1.3) Cooling part
The filled plug shells are continuously conveyed in an S-shaped serpentine path through the film feeding wheel (Figure 11), then seamlessly enter the cooling tunnel (Figure 12). The cooling tunnel features an innovative S-shaped cooling channel with a single temperature control point and a dual-stage, water-cooled system. This advanced cooling method allows for easy temperature adjustments tailored to the specific characteristics of each medication, ensuring a flawless, burr-free finish on the suppository tails.The cooling plate transmission utilizes a synchronized pulley motor system (Fig. 13), with speed adjustments accessible via a touch screen interface. A photoelectric sensor halts the process to prevent bolt shell breakage at the transition point. During transport, the charging part's shell avoids contact with any component, preserving the pristine surface of the formed plug shell. The cooled and solidified suppository then progresses to the sealing, shearing, and coding station (Figure 14).
1.4)Seal and print code part:
This station integrates a servo film feeding device (Fig. 15), heating batch number device (Fig. 16), triangular dotted line device (Fig. 17), driven film feeding device (Fig. 18), pre-cut film feeding device (Fig. 19), upper trimming device, shearing device (Figure 20), and an optional waste collection device (a vacuum cleaner can be added for enhanced collection).
The cooled plug shell is transferred to the servo film feeding device via the transition wheel, enters the heating mold, and proceeds to the batch number mold for coding. The batch number code can be customized and easily changed. The coded shells move to the triangular dotted line device for precise lower edge trimming and mid-grain cutting, ensuring each segment can be effortlessly torn apart. Cut waste is directed into the lower waste slot. Subsequently, the shell advances through the driven film feeding device to the upper trimming device for final shaping. Waste from this process is funneled into the lower waste groove. The shell then enters the pre-cut film feeding device, where the servo drive ensures accurate, controllable transmission positioning. The shearing device, controlled via touch screen settings, cuts the suppositories into the desired number of particles, allowing for flexible customization (ranging from 1 to 10 grains as needed).
