Floss fusing device for floss machine

Abstract

The invention provides a floss fusing device for a floss machine. The device comprises a floss pick upper die and a floss pick lower die, wherein a heating rod connecting plate is arranged above the floss pick upper die, the top of the heating rod connecting plate is provided with an air cylinder driving the heating rod connecting plate to move vertically, the heating rod connecting plate is connected with a hollow heating rod, the top end of the hollow heating rod is connected with an external air source, the positions, corresponding to the hollow heating rod, of the floss pick upper die andfloss pick lower die are provided with pore canals allowing the bottom of the hollow heating rod to be inserted in, and the hollow heating rod is located above the fused portion of the thread residueof a floss pick after extending into the pore canals. The floss fusing device for the floss machine firstly creates a non-contact type fusing method in the industry, avoids a series of defects of thecontact type fusing, and can effectively control the pulling force of a floss made from a nylon thread or a polyester thread material to ensure the flat shape of the floss, so that the thread residueof the floss is perfectly integrated with a product, and the floss pick product has a very perfect surface and standard-compliant quality and height.

Description

technical field [0001] The invention relates to a dental floss machine component, in particular to a dental floss machine fusing device. Background technique [0002] Dental floss picks, also known as dental floss picks, are products used in conjunction with toothbrushes in daily oral care. The dental floss stick has the advantages of convenience, high efficiency, safety and sanitation. A toothbrush can only brush 70% of the surface of the teeth, and dental floss makes up for the shortcomings of the toothbrush, and is a commonly used household tooth care product today. Dental floss can effectively protect the gums, remove plaque, soft dirt, and food residues. [0003] At present, due to the influence of production equipment, most dental floss in China generally uses polymer thread, and its diameter is generally greater than 0.12mm. This size is larger than the gap between the general teeth and gums, and the cleaning effect is poor. Long-term use will expand The gap betwee...

AI Technical Summary

Problems solved by technology

It is usually restricted by the very critical process of fusing dental floss in the production equipment. At present, the disconnection of dental floss usually has two states, one is cutting, and the other is fusing. The failure rate of cutting this method is high, and the thread end is exposed at the same time. Outside, poor quality, less used

The fusing of dental floss uses the heating rod to directly touch the dental floss to fuse. Because the temperature of the heating rod is very high, the dental floss will be melted quickly when it touches the dental floss, but the heating rod will stick to the floss after the first melting of the dental floss. The area of ​​the heating rod increases during the next fusing process, which will cause the heating rod to burn to the edge of the floss stick. At the same time, the temperature will be too high during the melting process, which will make the thread black and the plastic yellow. Sometimes If the temperature is too low, there will be wool, and hard knots will occur at the end of the thread
