Description
technical field
[0001] The invention relates to the field of extruders, in particular to a mixing type extruder for processing refrigerator door seals. Background technique
[0002] The refrigerator door seal is a kind of refrigerator accessory used to seal between the refrigerator door and the cabinet. It consists of two parts, a soft polyvinyl chloride (SPVC) jacket and a magnetic adhesive strip.
[0003] In the mixing extruder technology currently used for the processing of refrigerator door seals, most mixing extruders are often unable to adjust the extrusion port in time when the mixed material is processed and extruded to the required amount. Closed, easy to cause more extrusion during the extrusion process, and after extrusion, because the extrusion port is directly exposed to the air, when in use, the extrusion port is easy to be stained with dust, resulting in The phenomenon of impure mixing, so we designed a mixing extruder for refrigerator door seal processing t...
