Manufacturing method and manufacturing device of dental floss rod

Abstract

The invention discloses a manufacturing method and a manufacturing device of a dental floss rod. The manufacturing method successively comprises following steps: a combination moulding process, a cooling process, a burn-cutting process, a disconnecting process and a material collecting process. The combination moulding process includes steps: (1) enabling a dental floss body to be clamped by a dental floss rod die provided with a dental floss rod-shaped groove; (2) injecting plastic into the dental floss rod-shaped groove through a material injecting apparatus; (3) cooling the plastic to form a dental floss rod frame. The dental floss rod frame comprises a bracket and at least one dental floss rod, wherein each dental floss rod includes an opening part and a holding part so that a dental floss body can be arranged in a manner of being fixed onto two ends of the opening part. Each dental floss rod is connected to the bracket through a plastic rod body. A thermal burn-cutting process is carried out by means of a burn-cutting apparatus, wherein the thermal burn-cutting process can be performed in an electric-thermal burn-cutting manner or a laser burn-cutting manner. The dental floss body connecting the two outer edges of the opening part is burn-cut at 300-450 DEG C. A joint is formed by means of sintering at each burn-cutting position on the dental floss body. The joints are pressed against the two ends of the opening part so that the dental floss body is fastened on the two ends of the opening part. Finally the dental floss rod is separated from the bracket and is collected by means of a disconnecting process for performing punch-disconnection.

Description

technical field [0001] The present invention relates to a manufacturing method and equipment of a dental floss stick; more specifically, it refers to the use of electrothermal cutting or laser cutting to cut the outer edges of the two ends of the opening at a temperature of 300°C to 450°C. The floss body is burnt, and the burnt part of the floss body is sintered by the high temperature to form a pedicle, so that the floss body is divided into several pieces that are fixed between the two ends of the opening of the dental floss stick by the pedicle. Dental floss rod manufacturing method and apparatus. Background technique [0002] The purpose of teeth is mainly to tear food and chew food to facilitate swallowing. Therefore, if the teeth are damaged or collapsed, it will greatly affect eating and cause a lot of inconvenience, so the maintenance of teeth is very important; and Doctors also often recommend cleaning teeth once after eating, but for busy office workers, it seems ...

AI Technical Summary

Problems solved by technology

[0003] Among them, the dental floss stick is the most common dental cleaning product, and the invention of the dental floss stick allows users to remove foreign matter in the gaps between the teeth more reliably, and is more convenient to carry and use. However, the dental floss on the known dental floss stick Most of the fixing methods are to fix the dental floss on the outside of the dental floss stick with adhesives, or tie the two ends of the dental floss to the dental floss stick, or bury the dental floss in the dental floss stick, etc. The method allows the user to easily fall off the dental floss from the dental floss stick during use, and the adhesive has a certain degree of toxicity, which has a certain degree of impact on the user's health
