Abstract

The invention discloses a toothbrush and a production method thereof, and relates to the technical field of a toothbrush production process. The method comprises the following steps of: threading brush threads on a brush threading plate, wherein one end of each brush thread is arranged higher than the front of the brush threading plate; melting the brush threads on the back of the brush threading plate by hot melting and fixing the melted brush threads on the brush threading plate;, and then fixedly connecting the back of the brush threading plate at the front end of a brush handle through thermoplastic elastomer (TPE) or thermoplastic rubber (TPR). The brush threading plate can be fixedly connected with the brush handle by a general injection molding process of toothbrush production so as to overcome personal injury caused by a microwave treatment process and improve labor protection for operators. Because of the elasticity of the adopted TPE or TPR, impact on oral cavities in the tooth brushing process is avoided, and the protection performance for the oral cavity is improved. Because no metal is required for holding the brush threads, a series of harms caused by heavy metal is avoided.

Description

A kind of toothbrush and production method thereof
Technical field
The present invention relates to the toothbrush technical field of producing.
Background technology
Current toothbrushes is simultaneously to punch at the brush position of brush holder front end, will brush silk to plant in each hole after the wire clampings such as aluminium or copper or lead.Because have the gap between brush silk and the brush holder perforated surfaces, some composition and wire react in the toothpaste, form metal ingredient and leak, be unfavorable for health, therefore, in existing toothbrush standard, proposed the strictness of metal ingredient is limited.Nonetheless, also have the metal ingredient of a lot of finished product toothbrushes also to have the phenomenon that exceeds standard, bring healthy suffering to conceal to the user.
In order to overcome the above-mentioned defective that heavy metal causes, a kind of unwired toothbrush production technology has been proposed in the industry, to brush silk earlier is set in brush is sizable and wears on the hair plates, allow an end of brush silk exceed and wear the positive suitable height of hair plates, make bristle fuse and be fixed at the back side of wearing hair plates by hot melt and wear on the hair plates, make the front end that the hair plates back side is fixed in brush holder of wearing by microwave treatment then with brush silk.Though this technology need not the wire clamping be brushed silk, has solved the problem that heavy metal brings, in process of production, the operator places oneself in the midst of in the microwave environment, and the strong width of cloth that causes human body to be subjected to microwave is penetrated, and directly causes personal injury.In addition and since various toothbrush design to wear hair plates thickness different different with the thickness of brush holder, during the microwave treatment of employing varying strength, also can cause and wear hair plates or brush holder and swash and wear, waste product occur, therefore, the yield rate of this technology is not high, causes production cost high.
Summary of the invention
The object of the invention is to invent and a kind ofly is easy to process, the toothbrush of non-environmental-pollution, no metal.
The present invention includes brush holder, also comprise the hair plates of wearing that is fixed with brush silk, be characterized in: describedly wear hair plates is fixedly connected on brush holder by thermoplastic elastomer (TPE) TPE or TPR front end.
The present invention is by thermoplastic elastomer (TPE) TPE or TPR will wear hair plates and brush holder forms a fixed connection; only need general Shooting Technique by toothbrush production; can realize, overcome the personal injury of adopting microwave treatment technology to be brought, improve labour protection the operative employee.And the thermoplastic elastomer (TPE) TPE that adopts or TPR can avoid the bump of the process of brushing teeth to the oral cavity because it has elasticity, improves the oral cavity health care performance.Owing to need not metal clamping brush silk, a series of harm that also heavy metal free produced.
Produce for convenience, improve the fastness that is connected of wearing hair plates and brush holder, the present invention also is provided with groove at the front end of described brush holder, described wearing in the fixing described groove of hair plates.
Another object of the present invention provides a kind of production technology of above toothbrush:
Technical scheme of the present invention is: will brush silk earlier and be set on the hair plates, an end of brushing silk is exceeded wear the hair plates front, making bristle fuse and be fixed at the back side of wearing hair plates by hot melt wears on the hair plates, then, the back side that will wear hair plates by thermoplastic elastomer (TPE) TPE or TPR again is fixed in the front end of brush holder.
The present invention also can make groove at the front end of described brush holder earlier, and then by thermoplastic elastomer (TPE) TPE or TPR the described hair plates of wearing is fixed in the described groove when produce brush holder.
Technology of the present invention is simple, and working environment does not have microwave radiation, meets the requirement of cleaner production, and yield rate can improve greatly, is beneficial to save production cost.
