Manufacturer of fully automatic suppository continuous production line

The manufacturer of the fully automatic suppository continuous production line uses PVC and PVC/PE rolled packaging materials, which are blow molded into the shell bands required for suppositories through molds and intermittently enter the infusion section. The suppository mixture is made by mixing the powder with the matrix. After thorough stirring and homogenization, it is automatically filled into the suppository shell with high precision and sent to the cooling and shaping box by the conveying device. Under the action of cold air, it is rapidly cooled and shaped, completing the transformation from liquid to solid. After Zui, the sealing mechanism automatically seals the upper opening, prints the batch number and production date, trims the triangular dotted line, aligns the upper edge, and servo cuts it. Zui then enters the finished product packaging.

Fully automatic suppository continuous production lineIntroduction to each section

1. Molding and filling part

Composed of a film tray, servo conveyor fixture, forming, trimming bottom edge, filling pump, material bucket, and material circulation pump station, it completes the shell making and filling process of the film material (Figure 6-1)

Figure 6-1 Schematic diagram of molding and filling part

1.1 Molding

The packaging material aluminum foil is placed in the film tray A and B (Figure 6-2), guided by a guiding mechanism, and enters the forming station. This workstation has feeding, feeding, and cold pressing molds. After the single piece is formed, it is merged by the folding mechanism and enters the hot sewing mold for sewing and forming.

1.2 Filling

The formed plug shell enters the filling station. The filling station consists of a track, servo screw system, filling pump, insulation material bucket, mixer, electric heating system, screw circulation pump, and material circulation pipeline to complete the filling process. During filling, a servo screw system is used to ensure precise and stable filling volume. The filling volume adjustment is completed within the touch screen, with simple operation and precise control.

Figure 6-3 Schematic diagram of servo filling pump

The filling pump body has 7 plunger pumps, and the filling volume is controlled by the servo screw system at the top. The plunger shell enters the injection channel at the lower part of the pump body for filling 12 particles at a time. (Figure 6-3)

Materials are added to the material bucket and heated by heating elements to maintain a certain temperature. The mixer is driven by a variable frequency adjustable speed reducer motor, and the material circulation pump is composed of a screw pump (variable frequency adjustable) and its pipeline. The speed adjustment is easy to operate on the touch screen. (Figure 6-7)

2. Cooling box section

Figure 6-8 Schematic diagram of cooling box section

It consists of four sets of Eight Trigrams Plate Chain Conveyor System (Figure 6-9), Eight Trigrams Guide Membrane System, Transmission Maintenance System, Cold Water Pipeline, Insulation System, and Cold Exchanger. After filling, the plug shell is conveyed through the Eight Trigrams Plate inner chain and continuously enters the 2 # Eight Trigrams Plate after passing through the 1 # Plate (there is a transition device between the 1 # Plate and the 2 # Plate to prevent accumulation and breakage between them). It then enters the 3 # Plate for cooling and sequentially enters the 4 # Plate for cooling, completing the solidification process (Figure 6-8). The cooling temperature selected varies depending on the freezing characteristics of the materials. By adjusting the cooling temperature of the two cooling plates separately (variable frequency adjustable) (Figure 6-10), the desired curing requirements can be achieved. The rack is equipped with rollers and feet for easy relocation and positioning. The parameter settings are completed within the touch screen.

After filling, the bolt shell continuously enters the cooling track, and the chain is continuously sent to the sealing station after cooling (Figure 6-11)

Cold water is supplied by a chiller and evenly dispersed through a cold exchanger, with a temperature controlled between 8 ℃ and 16 ℃.

3. Closing completion part

After solidification, the strip is continuously fed into the mold preheating, sealing, and batch number mold (Figure 6-13) through the tail sealing servo conveyor mechanism (Figure 6-12) and the material guide groove mechanism for batch number printing. The batch number is changed according to the user's needs, and then the bottom and middle engraving lines are trimmed (Figure 6-14), the top edge is trimmed (Figure 6-15), and finally the servo film feeding disc (Figure 6-16) sends it into scissors (Figure 6-17) for final cutting and slicing into the set suppository products. Enter the discharge port and feed into the next process. The number of particles is set within the touch screen, which can be set arbitrarily and is easy to operate.

4. Human computer interface

The touch screen adopts Siemens ten inch screen, and the programmable controller adopts the original Siemens brand. The font is clear and the quality is reliable. All parameters are completed on the touch screen, making it easy to change molds and varieties. All alarms are displayed on the main control screen for easy maintenance.

Comparison Table of Equipment Performance

1. PLC detection function: Through the PLC online monitoring function, it can self check and alarm for operational faults, and synchronously display the cause of the fault, making it convenient for operators to troubleshoot in a timely manner.

The filling section is equipped with a static electricity removal system

Note: If the device is not included before the formed shell reaches the filling position, it may climb a small height along the inner wall of the shell under the action of electrostatic force when filling trace amounts of drugs, which may reach the sealing position of the plug. Therefore, it will affect the sealing quality later on.

3 Mixing bucket speed adjustment system

Note: Due to the different viscosities of the drug matrix, the fixed stirring effect may not be able to mix the drug evenly before filling, thereby affecting the drug content of the finished plug.

4 Cooling speed regulation system

Note: Different cooling rates may be required due to variations in drug composition; When the cooling speed is too slow, it will cause a decrease in the production efficiency of the entire machine; When the cooling rate is too high, it may cause the drug to break due to a sudden temperature drop, so the cooling rate needs to be adjustable The cooling temperature can be adjusted by frequency conversion. Screw pump ensures stable circulation of medication and improves filling accuracy.

5 adjustable cutting particle number system

Note: By adjusting the parameters through the touch screen according to customer needs, it is easy to set the number of finished particles as 1/2/3/4/5/6/7 /It can be cut arbitrarily.
