Mixing type extruder for refrigerator door seal machining

Abstract

The invention discloses a mixing type extruder for refrigerator door seal machining. The mixing type extruder comprises an extrusion pipeline; a driving device is connected with one side of the extrusion pipeline; an extrusion port is formed in the other side of the extrusion pipeline; a feeding hopper is formed in the top of the side, close to the driving device, of the extrusion pipeline; a vertical first connection frame is arranged on the extrusion pipeline on one side of the feeding hopper; a vertical second connection frame is arranged at the top of one side, close to the extrusion port,of the extrusion pipeline; a fixed sleeve is mounted in the upper inner side of the second connection frame; and one end of the fixed sleeve is connected with a first limiting block. During the use,the mixing type extruder is convenient to close the extrusion port in time to prevent redundant mixed materials from being extruded, and convenient to clean the dust on the outer side of the extrusionport when the dust falls to the outer side of the extrusion port; and a protection cover is closed one the outer side of the extrusion port to play a dustproof role for the extrusion port, so that the using of the users is more facilitated.

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...
