Description

A horizontal block raw material crushing and extrusion molding device Technical Field

[0001] The utility model relates to the technical field of granular ice making, in particular to a horizontal block raw material crushing and extrusion molding device. Background Art

[0002] Currently, the existing granular ice forming and processing devices on the market usually have two independent systems: crushing and extrusion, which have complex structures and relatively high costs.

[0003] In response to the above-mentioned existing problems, Chinese invention patent publication number CN114234509A discloses an ice-making module comprising an ice bucket, an ice scraper, and an ice squeezer. The ice scraper is disposed within the ice bucket, and its upper end is movably connected to the ice squeezer via a shaft sleeve. The ice squeezer is fixed to the upper end of the ice bucket and seals the upper end of the ice bucket. During the ice-making process, this prior art utilizes a drive mechanism to rotate the ice scraper within the ice bucket, scraping off ice formed on the inner wall of the ice bucket and pushing the scraped ice to the ice squeezer. The crushed ice below is continuously squeezed into the ice outlet of the ice squeezer, producing granulated ice. This prior art has a simple structure and low cost. However, this prior art still has structural deficiencies. When the ice scraper scrapes off larger pieces of ice, the force of the ice scraper's squeezing must be increased, which can also result in poorly formed granulated ice.

[0004] Therefore, there is still room for improvement and development in the existing technology. Technical Solutions
