Adjusting the die mode of a softgel capsule machine generally involves mechanical positioning, pressure adjustment, and electronic parameter synchronization. The exact procedure varies by machine model and control system, but the basic adjustment principles remain similar.
1. Mechanical Die Adjustment
Die Installation and Positioning
The upper and lower die shafts are installed on the machine spindle and mechanically aligned so that the die cavities match correctly when the dies close. Depending on the machine design, positioning may use graduated dials, locating pins, or other mechanical reference features.
Accurate die positioning is important for maintaining consistent capsule dimensions and preventing misalignment between the upper and lower cavities.
Pressure Adjustment
The forming pressure is typically controlled through pneumatic or hydraulic mechanisms. Operators need to set the pressure according to capsule size, shell thickness, and material characteristics.
Excessive pressure can increase die wear and may affect forming quality, while insufficient pressure may result in incomplete sealing. Hansheng Automation can machine precision die shafts, locating components, adjustment parts, and related mechanical components according to customer drawings, with critical dimensions controlled to meet assembly requirements.
2. Electronic Parameter Settings
Modern softgel capsule machines use electronic control systems to synchronize die rotation, gelatin ribbon feeding, and material filling.
Speed Synchronization
The die shaft speed is normally set through the main control panel and synchronized with the gelatin ribbon rollers and feeding mechanisms. Appropriate speed ratios help maintain stable material delivery and consistent capsule forming.
For custom mechanical components used in these transmission systems, we support drawing-based precision machining, including shafts, gears, bushings, couplings, and other non-standard parts.
Electronic Gear Ratio
Servo-driven machines can use electronic gearing instead of mechanical gear replacement when changing dies. Operators can set the electronic gear ratio between the die shaft and feeding pump directly through the touchscreen control system.
This approach simplifies format changes and allows the synchronization parameters to be adjusted more efficiently.
Filling Parameter Adjustment
Injection delay time and pump stroke can also be configured through the control interface. The objective is to ensure that the filling material enters the cavity at the correct stage of the forming cycle.
The exact settings depend on capsule size, material properties, die geometry, and machine configuration.
3. Die Alignment Calibration
Traditional machines may require manual rotation of the dies to complete mechanical alignment. Operators typically adjust the die phase while observing the alignment marks until the upper and lower cavities are correctly matched.
Modern servo-controlled machines may provide electronic alignment through the touchscreen. The operator can use fine-adjustment controls to change the die-axis phase position while monitoring the alignment status.
Accurate alignment helps prevent uneven sealing, dimensional deviation, and damage caused by improper die engagement.
4. Recipe-Based Parameter Management
Advanced softgel capsule machines can store multiple groups of production parameters, such as die speed, forming pressure, filling settings, and synchronization ratios.
When switching between capsule specifications, operators can recall the corresponding recipe instead of manually entering every parameter again. This reduces setup work and helps maintain consistent process conditions between production batches.
Overall, softgel die adjustment requires coordination between mechanical alignment, forming pressure, die rotation, feeding synchronization, and filling parameters. The specific adjustment sequence should always follow the machine manufacturer's technical documentation and the actual die configuration.
For the mechanical side of the system, Hansheng Automation provides custom machining for softgel capsule machine components based on customer drawings or samples, covering precision shafts, die-related components, gears, bushings, fixtures, and other non-standard parts required for equipment integration.
