Problems solved by technology

[0002] Toothbrush is the requisite tool for brushing teeth in people's daily life, and the pointed brush wire of toothbrush is owing to be easy to remove the tartar embedded in the interdental space, therefore, many toothbrushes all adopt pointed brush wire to make at present; The cleaning of the toothbrush tip brush in the process of toothbrush tip brushing. At present, the domestic cleaning of the toothbrush tip brush generally adopts two methods: manual hand washing and washing machine cleaning. These two methods clean the toothbrush tip brush. There are quality issues affecting the filaments of the toothbrush tips
During the cleaning process of the toothbrush pointed brush filaments, due to uneven force, it is easy to cause serious deformation of the verticality of the toothbrush pointed brush filaments, so that the finished toothbrush pointed brush filaments after cleaning appear "crescent". The post-finishing of the head brush filaments and the final product of the pointed brush filaments of the toothbrush cause certain quality problems; in addition, the traditional cleaning method generally adopts natural drying, resulting in a large increase in labor force, large occupation of space, and large waste of water resources. Facilitate large-scale production

Abstract

The invention relates to an automatic cleaning method of pointed brittles, in particular to an automatic cleaning method of pointed brittles of a toothbrush for processing both ends of each brittle into points by a strong alkaline solution, which comprises the process steps of soaking, cleaning, spraying, neutralizing, spraying, lubricating and drying the pointed bristles of the toothbrush. The invention finally obtains the high-quality pointed bristles of the toothbrush by mainly cleaning and drying the pointed bristles of the toothbrush. The invention can avoid rubbing the pointed bristles to reduce bent bristles of the pointed bristles of the toothbrush, and can improve the product quality of the pointed bristles of the toothbrush. Manual operation is reduced by an automatic delivery device, and the pointed bristles of the toothbrush are cleaned in warm water soaking environment by ultrasonic cleaning for many times. The invention can improve the production efficiency and achieve the purpose of continuous industrial production of products.
