577724 Printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 ______ B7 V. Description of the Invention (1) Background of the Invention The present invention relates to a method for manufacturing brushes, including: at least one bracket, and made of bristles made of The moldable plastic material thereon, wherein the bristles are made from the plastic melt and enter the bristles-shaped molding tank through the spray side. The invention also relates to a device and a brush for manufacturing brushes. The brushes, especially any kind of brushes in the present invention, are mainly made by machines, with a brush holder having holes at first, and then producing bristle bundles mechanically. With the use of plastic materials, the brush body has been manufactured by molding or spraying, and the bristles are either fixed by traditional mechanical methods or more recently by thermal methods. In any case, the bristles single fiber must be squeezed or rotated at the beginning. According to the method, the single fiber must be cuttable, and the bristles can be fixed to the bracket. With the recent traditional fixing technology, the bristles are looped and the metal holder is used to punch holes into the brush body. There have been many attempts to streamline the process by making bristles or bundles in one piece, together with a bracket, and connecting the bracket to the brush body. More than 100 years ago (GB788 / 1861, GB24 935/18 9), there have been proposals to mold the bristles and brackets, the bristles are connected there, and an elastic material such as rubber or the like is used to install them next to each other Hard brush body. The manufacture of the Jiejie element, connected in groups, and connected to the same bracket, adopts a common spray treatment, and the free choice of two brackets to connect the bracket to the brush body has also been proposed (DE941 364, GB2 151 971, USP 301 644, USP 4 2 4 4 076, this paper size it uses the Chinese National Standard (CNS) A4 specification (210X297 mm) '(Please read the note on the back 4 ▼ items before filling-Packing —: Write this page )

Invention Description (2) USP 5,0 40,260, USP 5,966,771, W98 / 03097), and finally, US Patent No. 5,926,900 has also been proposed for the manufacture of a full brush body and part of the bristles as an injection mold. These brushes are used only for hair care or-to a lesser extent-as discardable brushes. These brushes are not suitable for many applications because such spray die bristles have unacceptably low bending strength compared to those made by rotary processing. The bristles, which have no fixed molecular structure, are mainly characterized by the longitudinal component of the molecular chain in a parallel brush manner. For this reason, they must be identified as working or cleaning elements, not just bristles. The lack of fixing in the connection area of the working element to the bracket is of particular concern, where the orientation of the molecules is complete or not. Such a result The working element that is properly aligned directly after manufacturing will change its position after being used for a short period of time and will bend, break and cannot be straightened (bending recovery). This technology further requires that the working element and the bracket use the same plastic The use of materials increases the price, because high-quality bristles must be customized from high-quality plastic materials. Every effort to reduce the price will force the choice of plastic materials to be limited, because the disadvantages of considerations about use always exist. This kind of brush is suitable for new applications. The difference between the carrier material and the material for bristles, or the individual bristles on separate requirements is impossible, especially regarding mechanical strength, coefficient of friction, color and so on. Brushes with working elements ("needle") are conventional (USP 2 621 639), which are not actual bristles but needles, bolts, strips or the like. They are injection molded elements, which are mainly made of Paper size applies Chinese National Standard (CNS) A4 specification (210X297mm) • ϋ -ί 1! 1 n — &gt; il-一 丨 ϋ—Bl 1 ^ 1 —ϋ tm ϋϋ 士 ϋ I (Please read the Note: Please fill in this page again.)

Description of the invention (3) Rubber or elastic rubber plastic materials, such as elastomers, with a large cross section, They often have shorter bristles. In this brush, this "bristle" compression structure is absolutely necessary for two reasons: to obtain a satisfactory fixing force and fatigue strength; to avoid the molding groove for spraying being too narrow or deep, it has sufficient molding Charge to allow removal. These "pins" are characterized by their soft effect and increased friction coefficient on the treated surface. For example: they produce a stroke and massage, not an effective brush hole. The typical range of application is hair brushes, which are mainly used for For separating and arranging hair and massaging the head skin, the stiffness of these components will only be affected by the diameter to diameter / length ratio, just like the hardening of plastic. Brushes according to USP 2 6 2 1 6 3 9 are manufactured by injection molding. They are made by inserting a porous thin elastic bracket plate into an injection mold that matches the arrangement of the working elements. The mold has several groove-shaped molding cavities, which are connected. The bracket is porous and shapes the needle-shaped working element. The opposite side-the spray side-is provided with distributed grooves, which guide the plastic melt, such as nylon, to independent holes and adjacent molding grooves. The frame is directly widened after drilling to create a thickener on the two sides of the thin bracket plate, and in order to axially fix the working element in two directions, although the nylon used will be suitable for achieving the bristle-like characteristics, it is not here Use, however, because the fabrication of longitudinal molecular structures is not possible, at least at the foot of the element. The same situation is true in another conventional hair brush (EP-B 1 -0 1 2 0 2 2 9), in which the bracket is sprayed from the beginning, it has a sleeve-shaped cone protrusion, and another plastic material follows It is injected into the sleeve as a heart, which is adjacent to the opened sleeve end with a thickener. On the rear side, the heart is connected via a second bracket plate of the same material. This procedure is mainly for the application of the Chinese standard on the two paper sizes.

Description of the invention (4) Positive between the points The connection is fixed axially, making the working element less easy to move. (Please read the notes on the back before filling this page.) This type of cleaning element is also known in toothbrushes and brooms (USP 5 0 4 0 260, usp 5 966 771). These brushes have two parts. Finally, toothbrushes are known (usp 1 924 152, 2 1 3 9 242, DE 826 440, WO 00/64307), in which the bristles support consists of a combination of traditional bristles, whose use has been proven Good cleaning effect with needle-like cleaning element of bolt or elastic rubber plastic material. One of the objects of the present invention is to propose a method and device for manufacturing brushes. Among them, the conventional advantages of spray technology can be utilized. When the manufacture of brushes is allowed, the bristles have the same quality and use characteristics as the rotary spray bristles. According to the conventional method, the bristle-like working elements placed on the bracket are manufactured by spraying plastic melt into a groove to shape them, and the object of the present invention is achieved there. -Manufacturing brackets with perforations used as rotary nozzles (spinnerets), printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, and-holes, slots connected thereto, along at least a part of their depth, having less than Or equal to a minimum width of 3 mm,-where the ratio between this width and the flow path of the melt, derived from the depth of the perforation and the length of the groove, is less than or equal to 1: 5 and-the plastic melt is at least from the bracket On one side, the molten liquid is guided to the side to be sprayed through a hole and into a groove to form bristles. This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) 577724 A7 B7 Printed by the Consumer Cooperatives of the Intellectual Property Office of the Ministry of Economic Affairs 5. Description of the invention (5) The above ratio is preferably less than / equal to 1: 1 〇 The lower limit of this ratio can be in the range of 1: 2 50. The method of the invention paves a new path for the manufacture of brushes. Support, the bristles are placed on it and it forms the brush body itself or a part, such as the shape of insert or the like, and at the same time as a disposable "tool" for making brushes by spray molding. Because of the dynamic effect and the wall The frictional force, the tensile flow in the hole, acts on the rotating nozzle, which has a high shear force in the area close to the wall. These make the molecular structure flow direction oriented, which is in the melt or plasticized material. And continue into the bristle forming groove, where the ratio between the narrowest part of the perforation and the length of the melt flow path is selected according to the present invention, and the longitudinal molecular orientation has the best efficiency. The self-reinforcing force of this bristle passes The orientation of the molecular chain in the direction of the bristle is particularly significant for partially crystalline thermoplastic materials. Furthermore, compared to the manufacture of single-piece brushes, the brushes according to the present invention place short lengths of bristles in a carriage, for example: Its root or base, where it is supported, this root region is the most sensitive region relative to the hard, because the molecule is not or is not just slightly positioned at this position This fixation not only produces higher bending strength, especially bending fatigue strength, but also higher tensile strength. Regarding the brushes molded traditionally into a single piece, the bending strength of the required brushes intended to be biased can be increased by 40. % And more, and the elastic molecules are understandably increased because the tensile strength is also increased, and bristles with small cross sections and large lengths can be removed from the mold. Mainly, the method according to the present invention can be used to process all moldables Plastic materials, however, due to the characteristics of the brush, thermoplastic or thermoelastic materials or their mixtures (alloys) can be used, because these plastic materials are also aged (please read 4 notes on the back before filling and filling —: (Write this page) The size of the paper is in accordance with the Chinese National Standard (CNS) A4 (210X297 mm) 577724 A7 B7 Printed by the Intellectual Property Bureau Employee Consumer Cooperatives of the Ministry of Economic Affairs 5. The description of invention (6) lists the best molecular orientation. Main The ground is that not only any material can be used for the bracket, especially the plastic material which has different mechanical characteristics from the bristles. There are other improvements in the plastic material. , Color, or the like, and non-plastic materials, such as wood, metal, or the like. Perforations can be made by casting, melting, laser, injection molding, punching, drilling, or other independent materials on the carriage. They can be made in any arrangement. If the arrangement is closely spaced, it may be the method of the present invention. The bristles are closed together in the form of bundles, strips or packages, or the holes can be widely separated for individual manufacture. The upright bristles have a larger separation from it. It is also possible to combine such an arrangement with any contoured bristles. Finally, the perforations can also be axially parallel to the side section in order to divide the longitudinal side section to the bristles. In a preferred embodiment, the perforation itself is designed with a transverse and / or longitudinal cross-section, and / or the spray pressure is selected in such a way that the melt passing through the perforation undergoes a longitudinal molecular orientation at least in the area around the bristles, for example, it occurs at The bristles are spinning. The range of longitudinal molecular orientation will be affected by the absolute depth of the cross section and the hole. The narrower the cross section and the greater the hole depth, the higher the shear force when the melt is sprayed, and the shear flow is also affected by the spray pressure or spray speed. It has been revealed in the method of the invention that the higher the spray speed, the higher the bending strength of the bristles, especially when considering the ratio of the minimum hole width to the width and the flow path of the melt. The formation of shear flow is also affected by the shape of the perforations in the axial and radial directions. When the perforation has a cross section with a side profile, the shear flow in the profile of the side profile is subject to Chinese national standards (€ Milk) 8 4 specifications (210 father 297 mm) (Please read the notes on the back 4 items and then fill in-install — — write this page) Order No. 577724 Printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 ____B7 V. Invention Explanation (7) The movement will be larger than that in the heart. The reduced cross section from the ejection side to the opposite side produces a steeper velocity side profile on the external exit. The narrowing of the cone or stage produces a tensile flow. Excimer orientation. The perforations in the brackets are preferably deep, which is such that the sprayed bristles are surrounded by a drop in the area, where the longitudinal molecular orientation is insufficient, ie, for example, where the bristles are connected to region. The method of the invention also allows the bristles to be sprayed in different lengths so as to form the envelope surface at the ends of the bristles on the finished bristles, which are not flat. The perforation in the bracket acts on the rotating nozzle to produce a longitudinal molecular orientation, which is independent of the length of the bristles so that the bristles of different lengths have the same good bending behavior and recovery capacity. The molding grooves for the bristles can be correctly defined so that The topography produces precisely predetermined topography, which is sewn to separate use of the bristles. With traditional brushes, especially toothbrushes, this terrain is created by mechanical processing methods, which does not allow high accuracy. Brushes can also be formed by spraying to have different shaped ends to sew the effect of individual bristles or the entire bristle handle to achieve the desired use. In another method variant, the bristles are guided annularly over the perforation with a plastic melt to create empty bristles. In this case, the plastic melt is sprayed annularly through the opening and into the groove to make empty bristles, which are either open or closed at their empty ends. In the first case, they have the shape of a groove, in which the wall friction force creates a molecular orientation not only on the outside but also on the inner wall of the empty bristles, and the empty bristles can be filled with any suitable filling material. Or, after the empty bristles are sprayed and removed from the mold, another plastic melts (please read the precautions on the back before filling this page) This paper size applies to China National Standard (CNS) A4 (210X 297 mm) 577724 A7 B7 V. Description of the invention (8) (Please read the precautions on the back before filling this page) The liquid is sprayed into the empty space of the bristles to generate heart bristles, which also have longitudinal molecular orientation on the surface, because the Shear flow and friction on its inner wall. This makes a multi-synthetic brush, in which the plastic component can again meet the application 'The heart of the empty bristles can be composed of an inexpensive and / or hard material, and its exterior meets the purpose of using the brush, for example: to produce stronger The working layer with a polishing or polishing effect can also form a softer working layer on the outside; when such a layer is worn, the inside will be exposed and an indication of wear will be formed, especially when the inner wall of the empty bristles is different from the cover and the cover. Or the ejected heart can also be profiled sideways to improve adhesion, and the increased surface will also result in increased wall friction to further support the longitudinal molecular orientation for melt flow. The empty bristles can be sprayed to have perforations, and another plastic melt for heart bristles can be sprayed through the perforated projection bristles. This creates different structures on the bristles surface, which individually differ in the shape of the perforations and the selection of materials. In the shape of a nodule, finger, or thread, the perforation can act as a rotating nozzle with the appropriate well-known size. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs may also initially squeeze the heart bristles and be at least partially surrounded by sprayed plastic melt to form empty bristles. In another embodiment, at least one recess is provided on the supporting melt feeding side, and at least one hole is extended from there to the opposite side, wherein the recess is at least partially filled with bristle plastic melt during spraying. . This creates a corresponding melt reserve to provide additional melt into the brush as required, and in addition, this is either completely or partially interconnecting the dorsal sides of the bristles, thereby producing a positive fixation relative to the pull-out force The paper size of this paper applies the Chinese National Standard (CNS) A4 specification (210X297 mm) 577724 A7 B7 Employees 'Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. 5.

The depression can be continuously extended beyond the bracket side facing away from the brush, or can be placed in the form of grooves, which are arranged on the partition to form each other. Crossbone bone leading to the hole. After the bristle material is sprayed, the back parts of the bristles will be connected together through the elastic strips or bones in the depression. Generally, only the bristles need to be made of high-quality plastic, so a cost-effective structure can be obtained. Decorative effect. In another embodiment, a space-defining bracket, such as an at least partially cylindrical bracket, has an opening as a rotating nozzle, and the bristles are extruded from the inside with a plastic melt. This allows the manufacture of brushes with curved brackets, where the correct alignment and alignment of the bristles can be achieved compared to the mechanical fixing method, optionally including the situation where the ends of the bristles fit. According to an embodiment of the present invention, the bracket is used as a tube cross section, in which the bristles are sprayed through the hole with a plastic melt from the inside. This allows the manufacture of round brushes, eyelash brushes, etc., as well as any terrain shapes on the surface of the brush, which use bristles of different lengths, which cannot be understood by all or just using conventional techniques for the inappropriate use of round brushes. If at least one end of the pipe section is closed, such as the manufacture of toilet brushes, bottle brushes or the like, it can be manufactured according to the method of the present invention. Hollow space, which is defined by a bracket, can be at least partially filled with plastic melt for bristles.

It can be flat or have any curvature. The bristles can be sprayed. There are at least two different plastics. In the preferred embodiment, the bracket is perforated, which corresponds to the arrangement of the bristles in the complete bristle handle of the brush, wherein, as indicated above, bristles, strips or bags or individual bristles can be selected Permutations or combinations thereof. In another embodiment, the bristles sprayed through the bracket are stretched, just like the conventionally known bolt-shaped working element (DE 2 1 5 5 8 8 8), after spraying, and after the spraying work is distributed by a suitable tool. This can work directly after the ejection during work operation. The stretching in response to the tensile force will produce another molecular orientation in the longitudinal direction. In addition, the alternate elastic forces can be used to use the same molecular orientation to act. Increase the elasticity of the bristles, which can provide a degree of spare elasticity for curved bristles during use. In order to facilitate the application of tension via tension, protrusions, such as thickness, can be sprayed into the ends of the bristles, and tension is generated by tension, which extends the separation between the bracket and the protrusion, thereby allowing simultaneous thickness deformation. So that it is in line with the bristles, it is also possible to extrude protrusions, which connect some or all of the bristles together, and they will be separated later. Stretching can work in one or more steps, thereby reducing the tensile force in each step. Can be limited to the bristles.

In the context, the noun "depression , Refers to the mold cavity for connecting the bristles in any form, it can completely seal all the back part of the shrinking bristles 'or basically composed of individual bridges or bridges distributed to the grid bone' to connect the bristles to each other, The spare melt in the recess can supply additional false liquid to the bristles in response to the pressure in the spray unit. In a sturdy state, it creates a positive connection between the bristles and the bracket, and receives at least part of the action on the bristles It can also form a brush body together with the bracket. Because the bracket is clamped into the injection mold, the plastic melt of the bristles can be sprayed under high pressure, even when the bracket is not completely solid or Made of a flexible plastic material, such as an elastomer, because the nozzle opening is maintained to maintain its shape. In addition, at least part of the molding groove is on the side where it faces the bracket. The opening may have a cross-section that is tapered relative to the cross-section of the joint hole, which leads to additional restrictions on the melt flow and the longitudinal molecular orientation of the joint. The molding grooves may be of different lengths in order to provide the bristle ends of the finished bristle handle. To obtain a contoured working surface, the openings can be selectively separated from each other and different cross sections to obtain the corresponding density or low-density arrangement of bristles of different strength on the finished brush handle. The molding groove can have different end contours, For example: more or less spherical recognition, or extended to a point, the end of the molding groove can also be terminated in several thin capillary grooves to make a finger brush.

Description of the invention (1) Cold is used to increase the separation between the bracket and the protrusion to stretch the sprayed bristles. Similar to the extrusion of single fibers, the design invented by this device allows spraying after manufacturing. The improvement of the mold bristles increases the longitudinal direction of the polymer coefficient by stretching the entire length or the length of the bristles, which provides the brush with good bending strength, and especially the bending fatigue strength, thereby increasing the elastic coefficient. In this method, Even after spraying the bristles, it maintains its shape during extended use, and the surface hardness is improved.

In the description of the invention (28), due to the reduction in the cross section, the molecular chain is positioned vertically to a certain range. The wall friction force will generate cutting flow along the flow path of the melting liquid, and it will also generate a certain degree of molecular positioning, at least near the outer area of the surface of the spiral working element. The range of the longitudinal orientation is decisive for bending elasticity and bending fatigue. The strength and bending restore the eradicating element. As shown in Figure 2, the weakest point of the working element is the transfer area to the bracket 4, because the molecular orientation is completely insufficient, and it is generated only near the surface along the farther length. According to the inventive method of FIGS. 3 and 4, the bracket 6 is formed from the beginning, and the perforations are formed by rotating the nozzles. Preferably, the perforations are nozzle-shaped, which are used in the rotation technology. However, in the process of rotation, they may also have a simpler geometry, which passes through the longitudinal molecular orientation and starts in the pores, the main purpose of self-reinforcing. The bracket 6 of the illustrated embodiment includes a recess 8 on its back side, and the perforations extend therefrom. The bristled plastic melt is sprayed into the recess 8 from the ejection side indicated by the indicated arrow, while spraying through the perforations to the die groove of the injection mold (Not presented), which will be described later. The bristles are neatly connected to the plastic material 1 filled with depressions, especially shown in Figure 4. Because the shape of the perforation is smaller than that of the rotating nozzle, the indefinite orientation molecule 1 1 is initially oriented. When it enters the hole 7 and is almost completely Extending in the longitudinal direction of the bristles 9, traverse the longer path of the melt until they exit the bracket 6. The accompanying self-strengthening (by molecular orientation) gives the bristles 9 characteristics similar to those exhibited only by squeezing or rotating a single filament. FIG. 5 shows the complete bracket 6. It can form the body of the brush or at least its part, and therefore has a corresponding contour, and it has a lot of perforations. 7 (Please read the notes on the back first and then fill it out.

Description of the invention (29) The bristle handle is designed to form a bristle for each perforation, and the perforations are formed like a rotating nozzle (Figure 6 shows an ideal example). Using the terminology of rotation, the plastic melt produces a so-called melt in the depression 8. The spring 12 is inserted into the chimney in the form of a conical transformation section 13. This insertion chimney draws a guiding course 14 (so-called shear zone) of a cylindrical cross section, which is accompanied by a conical transfer zone 15 The reduced cross section leads to the so-called smooth route 16. The diameter-to-length ratio of the smooth path is between 1: 1 and 1 ·· 6. This shape of the hole 7 produces the best stretch and longitudinal orientation of the molecules in the bristles 9. In order to obtain a bristle-like structure, the minimum width of the perforation 7, for example: along the smooth path 16 should be less than or equal to 3 'The ratio of the bristle length to the minimum cross section of the hole 7 should be less than or equal to 1: 5, It is preferably less than or equal to 1: 10, where the ratio can be as high as 1: 250. The hole has been shown in the experiment, which has a smooth course of 16 with an entrance area gradually tapering down to its diameter, and accompanied by With a ratio of diameter to length ratio of 1: 4, it is guided to increase the wall friction with the melt flow in the spray speed to cause excellent self-reinforcing force of the bristles. A larger diameter to length ratio, for example: 1: 1, Conducive to the use of especially thinner and more flexible brackets. According to the configuration of hole 7 in Fig. 6, the inlet diameter of the 8.5 mm inlet funnel and the smooth path diameter of 0.5 mm are increased by a factor of 2 8 · 5. The higher the speed, the faster the speed distribution The steeper, and the better the shear force, it is extended to a longer range by cone transfer. The melting spring 12 according to Fig. 6 is used as a molten liquid supply in the conventional fiber rotation. According to the present invention, when the bristles 9 are sprayed, it is also melted.
