Use

Suitable for extruded rubber (EPDM, natural, butyl green, butyl, regeneration), used for building doors and Windows sealing strip, automotive sealing strip composite strip, single extrusion strip production and construction, electrical appliances, machinery, water conservancy and other different shapes of strip, strip, tube, plate and other dense and foamed rubber products.

Working stage

The work is divided into four stages: one stage, the machine must accept the feeding, conveying and compacting of the compound; In the second stage, the rubber material must be heated and plasticized to make it a movable block material; In the third stage, the extruder must mix and heat homogenize the compound; In the fourth stage, pressure is built up to force the compound through the die. For a hot feed extruder, the second and third stages are provided by a preheated smelter.

Use and maintenance of cold feeding equipment

1 hard gear surface reducer before use need to add 25kg-30kg oil (based on the oil label), add gear oil in summer, add 45 mechanical oil in winter, regular change can prolong the service life of the reducer.

2. Open the fixed cover of cold feeding regularly for 1-2 months/time, and maintain the feeding regularly. Adjust the gap between the copper knife and the feeding roll in the roller bearing, otherwise there will be glue leakage.

Before starting, calibrate the caliber die and tighten the Harvard flange and fastener.

4 Boot operating temperature between 40℃-70℃, the temperature is too low easy to damage the machine, the temperature is too high prone to vulcanization of raw rubber (cooked rubber), resulting in damage to the machine can not work normally.

5. Before shutdown, the glue in the barrel screw should be extruded clean, and the temperature of the barrel screw should be reduced to the indoor temperature with circulating water, otherwise it will affect the next use.

6 Precautions for use in winter: Antifreeze should be added to circulating water before icing to avoid damage to equipment caused by freezing and icing.
