AI Technical Summary
Traditional raw material addition equipment for the production of styrene thermoplastic rubber has the problem that powdered raw materials easily adhere to the inner wall of the equipment, resulting in insufficient actual input and a lack of precise weighing and ratio control, which affects product quality and consistency and increases production costs.
An equipment structure including a conveying threaded rod, a guide tube, a discharge barrel, a rotating plate and a discharge screw was designed. The cooperation of the rotating plate and the sealing plate ensures that the raw material powder falls from the bottom of the discharge barrel into the collection box. The discharge screw scrapes off the powder adhering to the inner wall, and the sliding frame and hook nail structure prevent dust from escaping. The dust is cleaned in combination with an air pump.
It effectively reduces the adhesion of powdered raw materials on the surface of the equipment, ensures the accurate input and mixing of raw materials, improves product quality consistency, and reduces raw material waste and production costs.

Due to the lack of precise weighing and proportioning control, the adhered powder not only affects the quality of raw materials, but also makes the proportioning of the final product inaccurate, thereby reducing the performance and consistency of the product. This situation may result in the production of styrene thermoplastic rubber that does not meet the specifications, affecting its performance in application. The adhered powder may also cause raw material waste, increasing production cost and not meeting the actual demand. SUMMARY
