Pharmaceutical companies are increasingly demanding filling machines, including the accuracy of filling and the efficiency of filling. In the pharmaceutical industry, filling machines are mainly for filling pharmaceutical products and are a small class of products in packaging machines.
In terms of the degree of automation of production, it is mainly divided into semi-automatic filling machines and fully automatic filling production lines. From the perspective of packaging materials, it can be divided into liquid filling machinery, paste filling machine, powder filling machine, particle filling machine and sauce filling machine.
According to the introduction of *, there are three filling methods commonly used when filling liquids. First, the atmospheric pressure method, the atmospheric pressure method is also called the pure gravity method, that is, under normal pressure, the liquid material flows into the packaging container by its own weight. Most of the free-flowing, gas-free liquids can be filled by this method.
The R method is also called the pressure gravity filling method, that is, under high atmospheric pressure, the packaging container is first inflated to form an air pressure equal to that in the liquid storage tank, and then flows into the tank by the weight of the liquid. Inside the packaging container. The vacuum method is filled under sub-atmospheric conditions, mainly including differential pressure vacuum type and gravity vacuum type.
Of course, the filling machine is also like a human being. If you do not replenish energy for a long time, or if you do not have proper rest, you will malfunction. When the filling machine is used in daily use, the filling of the ceramic pump filling system in the stoppering machine may be unstable. Some manufacturers of filling machines said that they can be considered from two points: mechanical structure and electrical control.
In general, the filling system includes a dosing system and a dispenser. The liquid dispensing system is mainly used for transferring the configured chemical liquid into the liquid separator or the liquid medicine bag, and the liquid dispensing device is a buffer liquid separation integrated tank and a closed liquid separator.
The filling part is mainly composed of a rotary valve motor and a drive unit, a multi-package motor and a drive unit, a transmission gear, a roller screw and a ceramic pump. The needle frame structure is mainly used to track and position the bottle for corresponding filling.
In terms of electrical control, the filling is performed by the position control mode of the servo motor, and positioning can be achieved. The following three points are all electrical: when the servo motor does not reach the set position, the servo motor alarms and stops the filling and equipment; at the same time, the control of the rotary valve is the same as the control of the filling pump; the reciprocating and lifting control of the needle holder.
*Analysis, the amount of filling is generally not due to the production of dripping liquid or bubbles, you can use special sterilization equipment as much as possible; do not mix the pump body and pump rod; try to reduce the height difference of the installation position of each component, if you can not reduce Add a buffer device between the buffer tank and the pump; increase the number of tests after each pump is installed. If the connection slip is too large, it is recommended to replace it.
In addition, if the needle holder is fastened, if it is not fastened, replace the fasteners. The silicone tube should be reduced in length as much as possible. If there is still shaking, add a fastener in the middle. Of course, it is also necessary to add different suckback formulas according to different drug processes, and call different back sucking formulas under different conditions.
If you want the filling machine to work efficiently and have a long service life, the user should also regularly maintain and maintain the filling machine equipment. You can observe the moisture filter and the oil mister of the pneumatic combination two-pieces before going to work every day. If too much water is accumulated, it should be removed in time. If the oil surface is not enough, it should be refueled in time. During the production, the mechanical parts should be inspected frequently to see if the rotation and lifting are normal, whether there is any abnormality, and whether the screws are loose.
Always check the grounding of the filling machine, the contact requirements are reliable; often clean the weighing platform; check the pneumatic piping for leaks, and whether the air pipe is broken. The user also needs to replace the lubricating oil (fat) every year with the reducer motor, check the chain tightness, and adjust the tension in time. If you stop using it for a long time, empty the material in the pipe.
The user should do a good job of cleaning and keeping the surface of the machine clean, and often remove the accumulated material on the scale body, and keep the inside of the electric control cabinet clean. In addition, the sensor is a high-precision, high-sealing, high-sensitivity device. It is strictly prohibited to impact and overload. It must not be touched during work. It is not allowed to disassemble for non-overhaul.
