Automatic sand cutting machine

Abstract

The invention discloses an automatic sand cutting machine which comprises a sand cutting box 1, a base 2, a feed port 3, a discharge port 4, a comb tooth belt machine 5, a first tooth roller 6 and a second tooth roller 7. The sand cutting box 1 is provided with a cavity structure and fixed to the base 2. The feed port 3 is formed in the top of the sand cutting box 1. The first tooth roller 6 and the second tooth roller 7 are arranged on the two sides of a cavity of the sand cutting box 5 respectively. The comb tooth belt machine 5 is arranged below the first tooth roller 6 and the second tooth roller 7 in an inclined manner. The comb tooth belt machine 5 comprises two belt wheels 12 and a comb tooth belt 10. Multiple comb tooth pieces 11 are fixed to the upper surface of the comb tooth belt 10. The discharge port 4 is formed below the comb tooth belt machine 5 in an inclined manner. The automatic sand cutting machine can crush and decompose sand lumps efficiently, has a sand drying function, and then achieves a good sand cutting effect.

Description

technical field [0001] The invention relates to the field of casting processing, in particular to an automatic sand loosening machine. Background technique [0002] Sand is the most commonly used mold material in the foundry processing industry, but the raw materials of sand are prone to moisture absorption and agglomeration during long-term transportation and stacking, which seriously affects the casting effect of the sand core model and greatly reduces Productivity in foundry shops. [0003] At the beginning, artificial sand raising and loose sand were used, which was inefficient and costly. At present, most of the small sand loosening machines have poor sand loosening effect and low sand loosening efficiency, and the casting quality and efficiency of the sand core model still need to be improved. Contents of the invention [0004] The purpose of the present invention is to provide an automatic sand loosening machine, which can efficiently realize the crushing and deco...
