Description

TECHNICAL FIELD

[0001] The utility model relates to nylon production equipment technical field, specifically relates to a kind of slice feeding online oxidation detection system. BACKGROUND

[0002] In modern industrialized production, slice intelligent centralized conveying mode has become one of the important means to improve production efficiency and reduce production cost. Especially in the production and processing field of nylon chip, the application of intelligent technology has significantly improved the automation level of production line, and realized the whole-process intelligent management from raw material input to finished product output. However, in this efficient production process, the oxidation problem of nylon chip gradually highlights, and becomes an important factor affecting the quality stability of production line.

[0003] Nylon chip, as an important high polymer material, is widely used in textile, clothing, automobile, building and other fields. Its production process is complex, involving raw material blending, polymerization reaction, slicing, drying and other links. Under the mode of intelligent centralized conveying of chip, nylon chip is efficiently conveyed through automatic production line, but in this process, due to the influence of environmental humidity, temperature, illumination and other factors, nylon chip is easy to oxidize, thereby affecting its physical properties and chemical stability.

[0004] After the oxidation of nylon chip, its color may change, such as yellowing, blackening, etc., which not only affects the appearance quality of the product, but also causes the mechanical properties to decrease, such as tensile strength, elongation at break and other indicators. Oxidation also causes changes in the internal structure of the chip, increases its brittleness, and makes the chip more prone to break or break in the subsequent processing process. These problems directly affect the quality stability of nylon chip products, and further cause customer complaints and returns, etc., causing economic losses and reputation risks to enterprises.

[0005] Under the mode of intelligent centralized conveying of chip, although the production line has high automation level, in the face of the problem of oxidation of nylon chip, the existing system still faces many challenges. Intelligent system is difficult to monitor the oxidation of chip in the conveying process in real time and accurately. Even if the oxidation problem is found, the system lacks effective measures to stop loss in time. Therefore, how to introduce effective oxidation monitoring and prevention mechanism in intelligent conveying system has become a technical problem to be solved at present. UTILITY MODEL CONTENTS
