AI Technical Summary
Existing batching machines lack a structure for filtering raw materials, resulting in large differences in particle size when mixing different raw materials, which increases production costs and affects degradation rate and tableware quality.
A batching machine for the production of biodegradable disposable tableware was designed, which includes an inclined screening screen and a grinding cylinder. Small particles of raw material are screened out through the screening screen, and the large particles of raw material after screening enter the grinding cylinder for crushing. The grinding roller is driven by a rotating rod to achieve the re-grinding of large particles, thereby improving the uniformity of raw material particle size.
Screening and grinding processes improve the uniformity of raw material particle size, reduce the defect rate of tableware processing, and ensure the quality and degradation rate of tableware.
