Description

A kind of manufacture method of brushing tool and the product of manufacturing thereof

The present invention aims to provide a kind of method of brushing tool and brushing tool made from the method made.

The manufacture of existing brushing tool generally is that bristle material is inserted in the bristle hole, and fixed with the bonding jumper embedding, or ties up attached formation with line, or kinking bristle with two wires makes.This plants a mao operation, the general only suitable hair of planting in the plane on feather planting machine, and feather planting machine all has certain requirement to the big or small spread length in bristle hole, and plant mao part head thickness can not be thin excessively, as reducing head thickness, it is shallow excessively to plant pore, and then bristle is implanted insecure, can make brush smaller and more exquisite and reduce head thickness, the convenient use.Planting in mao technology of shoe brush, generally finish by manual, cut flat bristle face again, work efficiency is lower, and shear long bristle, the waste bristle material, brush body plants that hair is general only plants hair on a face of brush or two, three planes, if at the comprehensive hair of planting of brush, or to make arc surface or irregular surface with planting hair side, and plant hair thereon and then plant the hair difficulty, if making the bristle of diameter 10 hairs rolls, bristle roller bearing diameter is 2 hairs, and bristle length is 4 millimeters, adopts plug-in type to plant hair and makes then very difficulty.It is little to make various mechanical type brushing tool bristle face, plants hair and also seems difficult.

I have proposed to address the above problem with the form of chain type bristle in the ZL96245962.3 patent, need to implant many bristles on the brush body but discovery still exists with the chain type bristle form in brushing tool manufacturing process, operation is more numerous, and if plant with the form of inlaying and respectively to plant hair side in brush body, as arc surface, open embedding groove on the irregular surface, embedding groove shape complexity slightly promptly is difficult to finish, and embedding groove is less, enforcement still has certain difficulty, and on the chain type bristle inlay the ridged attitude slightly complexity also be difficult to finish, on each face of brush, open many embedding grooves, also comparatively complicated, claim 2 mentions that making of chain type bristle is characterized in that being the available plastics of chain base in this patent (ZL96245962.3), rubber or resin are made, the lotus base can combine with bristle, or the chain base into two, clamps bristle and rejoins.As by wherein said bristle and the chain base made respectively, two parts engage again, because chain type bristle chain base cross section is little, engage with the bristle filaments end face and to implement difficulty, particularly the chain base into two, clamping the bristle mode of rejoining, to make the chain type bristle more difficult, so the present invention proposes the manufacture method that more last patent is easy to realize the chain type bristle, and in the present invention the application mode of chain type bristle has also been done expansion, proposed to use the chain type bristle among the present invention, further bonding or inlay, make the sheet bristle, combine with brush body by the sheet bristle again, combine with brush body on the hair side and no longer just directly plant, make the chain type bristle be used for the system brush more easily at brush.The sheet bristle mode that proposes among the present invention has solved the problems referred to above.Because of the sheet bristle has omitted numerous embedding grooves of the required manufacturing of chain type bristle, become simple thereby make brush plant the hair side shape, be easy to make, and each plants hair side and only needs bonding or inlay a sheet bristle, also make the system brush seem more simple.

Consider the problems referred to above, the invention provides a kind of method of making brushing tool, solution is planted in complexity and is planted the hair difficulty on the hair side, improve the bristle material utilization rate, improve the mechanical degree of animal hair system brush, make and comprehensively on brush plant hair and have complexity that to plant the brushing tool and the small-sized machine formula brushing tool of hair side easy to manufacture.Can produce brushing tool more exquisite, more convenient use.

Its main idea of brushing tool manufacture method of the present invention is to make a bristle base 1 at an end of bristle filaments, bristle filaments is attached on the bristle base, the bristle base is chain, sheet, the concrete shape and the requirement of planting hair side by brush body cuts into chain, sheet bristle again, and with its inlay, bonding, be wrapped in brush body and plant and make brushing tool on the hair side.

The preparation method that the present invention makes the bristle base is:

Make bristle base or the bristle one end hot melt plastics that reinject at plastic bruss batt material one end hot melt and make the bristle base jointly, the manufacture method of bristle base is at first to make the chain bristle, make sheet bristle base behind the bristle base by chain bristle hot melt chain bristle again, also directly hot melt plastic bruss batt material one end is made sheet bristle base.

Or at bristle material one end coating adhesive formation bristle base, or the bonding bristle material of coating adhesive and other part of bristle base, for example: sewing thread, lining cloth are formed the bristle base jointly.

Or make sheet, chain bristle with knitting or flocking method, the chain bristle of making is bonding again or be embedded in and form sheet bristle or bigger chain bristle on the bristle substrate plate.

Advantage of the present invention is: owing to need not plant hair planting on the hair side perforate, so can attenuate brush base plate thickness.For example: general toothbrush base plate thickness is that 5 millimeter can be reduced to 1 millimeter with this method, makes toothbrush do more exquisitely, and the mouthfeel that rises is little.Make especially for children's toothbrush, more can be suitable for children oral cavity characteristics.Can make and plant the restriction that hair is subjected to brush body to plant hair side shape and duty and diminish, be convenient to various complexity plant plant hair on the hair side and on brush the comprehensive hair of planting, and improve the bristle material utilization rate, and this method can improve the mechanical degree of system brush.Particularly improve the animal hair stock utilization.Can on tiny bristle roller bearing, reach little planting for a short time of bristle rotating band easily and plant hair on the hair side.
