Description
Technical field
The present invention relates to a kind of auto-cleaning method of hair at top of tooth-brush, specifically relate to a kind ofly will brush silk two is processed into the hair at top of tooth-brush behind the tip through strong alkali solution auto-cleaning method.
Technical background
Toothbrush is the requisite apparatus of brushing teeth in people's daily life, and the pointed bristles of toothbrush is owing to be easy to the calculus removal that is embedded in the teeth space is fallen, and therefore, present many toothbrushes all adopt pointed bristles to make; And the cleaning to hair at top of tooth-brush in producing the hair at top of tooth-brush process, what present domestic cleaning hair at top of tooth-brush generally adopted is that artificial hand washing and washing machine clean dual mode, and all there are the quality problems that influence hair at top of tooth-brush in these two kinds of methods when cleaning hair at top of tooth-brush.In cleaning process to hair at top of tooth-brush, because the firmly uneven gross distortion that causes the hair at top of tooth-brush perpendicularity easily, make the hair at top of tooth-brush finished product that cleans out " crescent shape " occur, thus the back road arrangement of hair at top of tooth-brush and the product of final hair at top of tooth-brush are caused the certain quality problem; Traditional in addition cleaning way generally adopts nature to dry, and causes the labour significantly to increase, adverse effect such as occupied ground is big and water resource waste is big, is unfavorable for large-scale production.
Summary of the invention
The auto-cleaning method that the purpose of this invention is to provide a kind of hair at top of tooth-brush to avoid rubbing, reduces the curved silk of hair at top of tooth-brush, to improve the product quality of hair at top of tooth-brush.
The auto-cleaning method of hair at top of tooth-brush of the present invention is a continuous procedure, be to the cleaning of hair at top of tooth-brush and the improvement of baking step technology, comprise immersion, cleaning, spray, neutralization, spray, lubricated stoving process step in the method for the invention hair at top of tooth-brush;
1) the bundled hair at top of tooth-brush that will prepare is not untied binding, directly place the fermentation vat that mass percent concentration is 0.1%～15% aqueous hydrochloric acid solution is housed, the tip direction that keeps silk vertically upward, the liquid level of the aqueous hydrochloric acid solution in the fermentation vat is higher than the vertical height of hair at top of tooth-brush; It is 40～80 ℃ that aqueous hydrochloric acid solution in the fermentation vat is heated to temperature, is incubated 30 minutes changed aqueous hydrochloric acid solution (mass percent concentration of the aqueous hydrochloric acid solution of replacing is 0.1%～15%) after 3 hours to be incubated 30 minutes to 3 hours once more;
2) the soaked hair at top of tooth-brush of step 1) is sent in the service sink by automatic conveying device (as conveyer belt etc.), by quality requirement the hair at top of tooth-brush in the service sink is carried out ultrasonic wave simultaneously and clean, oil stain on the hair at top of tooth-brush, dirt, fine particle etc. are come off;
3) with step 2) hair at top of tooth-brush crossed through cleaning treatment is sent under the spray equipment through automatic conveying device (as conveyer belt etc.), water spray hair at top of tooth-brush, the residue that the dependence hydraulic pressure that shower water produced will remain on the hair at top of tooth-brush cleans up;
4) to place mass percent concentration by automatic conveying device (as conveyer belt etc.) be 0.1%～15% aqueous hydrochloric acid solution to the hair at top of tooth-brush that step 3) is cleaned up, and makes the hair at top of tooth-brush surface be in the acid-base balance state, to satisfy instructions for use;
5) hair at top of tooth-brush that the step 4) neutralisation treatment is good is sent under the spray equipment through automatic conveying device (as conveyer belt etc.), water spray hair at top of tooth-brush, and the residue that relies on hydraulic pressure that shower water produced will remain on the hair at top of tooth-brush cleans up;
6) hair at top of tooth-brush that step 5) is cleaned up places lubricating fluid by automatic conveying device (as conveyer belt etc.), regulate ultrasonic frequency, hair at top of tooth-brush in the lubricating fluid is carried out ultrasonic, the surface of lubricating fluid and hair at top of tooth-brush is fully contacted; Take out hair at top of tooth-brush and send in the drying unit by automatic conveying device (as conveyer belt etc.), the speed of adjusting automatic conveying device (as conveyer belt etc.) was controlled corresponding drying time 30 minutes to 3 hours, obtained the finished product of hair at top of tooth-brush.
Described frequency of ultrasonic is 2～200KHZ.
Described lubricating fluid is the amido silicon oil aqueous solution; Its mass percent concentration is 0.1%～10%.
The transmission speed of described automatic conveying device (as conveyer belt etc.) is 0.2m/min～8.5m/min.
The temperature of described shower water is controlled at 5 ℃～60 ℃.
The present invention mainly is to the cleaning of the hair at top of tooth-brush of unassembled one-tenth toothbrush and oven dry, thereby obtains high-quality hair at top of tooth-brush finished product.The present invention can avoid rubbing, reduces the curved silk of hair at top of tooth-brush, can improve the product quality of hair at top of tooth-brush.Reduce manually-operated by electronic speed governing automatic conveying device, utilize warm water repeatedly to soak hair at top of tooth-brush is cleaned up with ultrasonic wave.The present invention can enhance productivity, and reaches suitable Product industrialization quantity-produced purpose.
