Continuous production line for PU filter end caps are a kind of specialized equipment used to produce rigid and half-rigid PU filter end caps. Its operation principle is as follows: Raw materials are injected into moulds automatically running along a preset locus after being agitated in the low-pressure reaction injection machine. Then after inserting a element, the injected mould will be transferred onto the streamline with mating fixtures, waiting for ripening and hardening into shape. Constituents of the equipment Continuous production line for PU filter end caps is consisted of low-pressure reaction injection machine, automatic turntable and ring-shaped conveying line. Model R2S machine with a LCD touch screen as the man-machine interface employs NC automatic turntable to complete material injection into the mould. The turntable is driven by digitalized ETN200 double-axle servo-controller. Model R2S machine's features are listed hereby: 1. Module design with the integration of controller, actuator and operational panel. 2. Location through point to point method between two axles, clearance compensated through a slant line. 3. Huge resource for software-conducting operation and information memory. 4. Two axles utilize DC servo-motors with fully-closed circuit control system. Model LJ machine uses mechanical contouring method to finish material injection with an automatic turntable, which is driven by a mechanically-driven speed-variable electromotor and has a template below. Such machine has the advantage of low price, suitable for mass, uniform and simple production. Model X conveying line with speed-adjustable function for curing air-filters is a kind of special auxiliary equipment for making PU polyfoam products, moving in a smooth and reliable way. Baking channel of the line adopts electrical heating with evenly-distributed temperature.
