Capsule filling machine is a kind of high-efficiency equipment that realizes the synchronous positioning, filling and locking of capsules through the precision indexing turntable system, and its modular station design can complete the continuous production of multiple capsules in a short time, while ensuring that the dose error rate is less than ±1%. In addition, the capsule filling machine has many advantages such as fast arrangement, high efficiency, simple operation, convenient maintenance, and low power consumption, making it widely used in pharmaceuticals, health care products and other fields with strict requirements for hygiene standards and production capacity
In the process of serving the capsule filling machine manufacturer for a long time, we have also gradually learned about the structure of the capsule filling machine.
The automatic capsule filling machine is composed of an empty capsule blanking device, a capsule distribution device, a powder blanking device, a metering disc mechanism, a capsule filling and sealing mechanism, a main transmission mechanism in the box and an electrical control system.
1. Empty capsule blanking device: It is composed of a hopper and a conveying pipeline, which mainly stores empty capsules and makes the empty capsules vertically enter the capsule sub-assembly device one by one.
2. Capsule dispensing device: through the coordinated action of horizontal fork and vertical plug, six capsules are distributed into the module hole each time, and the vacuum separation system accurately separates the capsule and cap.
3. Powder blanking device: It is composed of a powder hopper, a powder hopper screw, a blanking conveying pipe, etc., and the powder is supplied quantitatively through screw stirring and screw conveying.
4. Metering disc mechanism: according to the capsule specifications and the matching metering disc specifications. The powder is packed and compacted into a column in an intermittently rotating dosing disc and pushed into the capsule of the lower module.
5. Capsule filling and sealing mechanism: when the capsule under the capsule of the medicine column is pushed, the upper and lower modules accurately buckle the capsule and the capsule cap through mechanical pressure.
6. The main drive mechanism in the box: the cam indexing table is driven by the frequency conversion motor, and the gear pair and chain drive are combined to achieve accurate indexing and speed regulation functions.
7. Electrical control system: controlled by PLC system to display the process elements of each capsule filling.
The working principle of the fully automatic capsule filling machine
The automatic capsule filling machine drives the mold module of the capsule through 8 stations of bladder broadcasting, cap splitting, cap body displacement, filling, rejection, locking, cleaning and bladder discharge through the rotary cam indexer system, so as to realize the automatic process of quantitative filling of capsules. After the equipment is started, the empty capsules are first arranged in a directional manner through the vibrating hopper and the horizontal fork at the bladder spreading station, and vertically enter the distribution device; Subsequently, at the sub-capsule station, the vacuum negative pressure system (about -0.05MPa) uses the difference in the pore size of the upper and lower modules to accurately separate the capsule cap and the body, in which the capsule cap is adsorbed on the upper module and the capsule falls into the lower module; The core filling station adopts the compaction metering disc technology, and the powder is compacted layer by layer in the intermittent rotating metering disc to form a medicine column, and is accurately pushed into the capsule through the filling rod, and the dose error can be controlled within ±1%; After the filling is completed, the equipment rejects the capsules that are not separated or filled abnormally through sensor or mechanical detection at the rejection station, and the qualified capsules enter the capsule locking station, and the upper and lower modules are accurately aligned under mechanical pressure to fasten the capsule cap with the capsule; Finally, the residual powder of the mold is cleaned by the dust collection system at the cleaning station, and the finished capsule is ejected from the bladder station to complete the cycle. The whole process is coordinated by the PLC system with the indexing accuracy of the cam splitter and the variable frequency speed motor to achieve efficient production of more than 3,500 grains per minute.
