Description

Technical Field

[0001] This utility model relates to the field of rice milling roller processing technology, specifically to a straight groove and large lead spiral sand roller grooving device for rice milling. Background Technology

[0002] The manufacturing of rice milling rollers belongs to the grain processing and rice milling wheel manufacturing industry within the machinery industry. The manufacturing process is quite special, involving processes such as material distribution, mixing, mold forming, kiln drying, processing, and kiln hardening.

[0003] After the rice milling roller blank is dried, it must be machined to achieve the dimensional accuracy required by the drawings. The surface of the rice milling roller is designed with various geometric cross-sections of grooves, generally including triangular spiral grooves and straight grooves. In existing technology, there are separate spiral groove processing machines and separate straight groove processing machines. However, the spiral groove processing machines have certain limitations. They can generally only process spiral grooves with small leads, such as leads below 500mm. Larger leads above 500mm cannot be processed. The larger the lead, the worse the dimensional accuracy of the processed groove becomes, making it more difficult to meet the requirements of the drawings. Utility Model Content
