Method used for producing floss picks by wire groove sintering

Abstract

The invention relates to an oral hygiene product, and specifically relates to floss picks prepared by wire groove sintering. According to each floss pick, a dental floss is pre-fixed at clamping ends of a rod body mould via a wire drawing device, and integrated molding of the dental floss and the rod body is realized by injection molding. The method comprises following steps: (1) preparation of raw materials; (2) molding of the floss picks; (3) sintering and fusion; (4) the obtained products are delivered to a cutting zone so as to separate the products and a feed port; and (5) transferring and packaging of product. According to the method, integrated injection molding of the dental floss and the rod body is realized; the part of the dental floss protruding out of the clamping ends is cut by sintering, and thread residue at the sintering part is buried in a preset groove, so that stability and toughness of the floss pick are improved; row type injection molding process is employed so that production efficiency is increased; in appearance, gaps and closed angles caused in cutting process are avoided by high-temperature sintering; the dental floss will possess fresh flavor if the dental floss is coated with natural essence such as mint or fruit essence.

Description

technical field [0001] The invention relates to an oral cleaning product, in particular to a manufacturing process of a dental floss stick produced by a slot sintering method. Background technique [0002] Dental floss stick, also known as dental floss pick, is a product that is used together with a toothbrush in daily oral care. Usually, a toothbrush can only brush 70% of the upper surface of the teeth. Dental floss makes up for the shortcomings of toothbrushes. Commonly used household tooth care products, the molding method of conventional dental floss sticks is to install the dental floss on the stick body, which will cause unstable installation or unreliable straightness and toughness, making the dental floss stick a disposable product. And defective products will increase the cost of use virtually. At the same time, the dental floss is made of pure nylon silk and other single-layer dental floss without any auxiliary fragrance or fruity taste, which does not bring enjoym...
