Description

The technology of approved production of national standard shuttlecocks by quality monitoring

The present invention relates to a kind of production technology of GB shuttlecock, particularly a kind of production technology that adopts approved production of national standard shuttlecocks by quality monitoring.

At present, shuttlecock is manufactured factory both at home and abroad, no matter be new factory or old factory, the production GB of all can not finalizing the design shuttlecock, all be to adopt method for screening picks out minute quantity in thousands of shuttlecocks ball up to standard, caused the production quantity of GB ball can't guarantee that supply falls short of demand as the GB ball, and inferior on the other hand ball overstocks in a large number, has caused great waste.

Purpose of the present invention is exactly the Quality Control legal type production technology that a kind of GB shuttlecock will be provided, and it directly produces qualified GB shuttlecock by the control that is rigid in checking up to critical component in the shuttlecock production process and critical process.

The present invention realizes in the following way: the inventor to the further investigation of GB shuttlecock and pterylology, finds that can shuttlecock up to standard by for many years, except that quality want up to standard outside, key is that can inherent quality up to standard.External quality up to standard is whether apparent size, color and luster, weight in grams number of shuttlecock etc. meets the requirements, and this has been explicitly provided thing, and is also controlled in process of production easily, is difficult in the up to standard of inherent quality.Inherent quality is mainly reflected on " surely ", " standard ", " jail " three big indexs, surely is that shuttlecock flight will be stablized, and does not turn a somersault and does not wave, can be according to predetermined orbital flight; Standard i.e. hit exactly, and depart from about not taking place or front and back; It is strong durable, indeformable that promptly want in the jail.This three big index is to complement each other, and is indispensable.Reach above-mentioned three big indexs, key is: one, bulb weight will equal to urge the into amount of thinking highly of, and this is that shuttlecock is not turned a somersault, and does not take place in advance or the assurance that lags behind and degenerate; Two, the center of gravity line of shuttlecock will overlap with the axis, and the direct current gas column that forms in urging device in the flight course also will coincide with the axis, and this is not wave in the shuttlecock flight course, can be by the key of orbital flight.The present invention just is based on the basis that above-mentioned theory is understood in depth, by production technology to the shuttlecock bulb, the production technology of workprint, urge the in addition quality control of packaging technology of device into, guaranteed that the shuttlecock of producing can satisfy surely in external requisite quality, accurate, jail three big in index.

The present invention is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is GB shuttlecock technological process of production figure.

Fig. 2 is GB badminton structure figure.

At first introduce the production technology of bulb, with reference to Fig. 1, the bulb production technology is made up of choose, process the bulb base, bag PU skin, boring four procedures of bulb base material.Bulb base material adopts Portugal's one-level cork double layer composite board, this plate constitutes by soft or hard is two-layer, at first sheet material is processed into small cylinder one by one, the end face of the hardwood layer periphery of small cylinder as bulb, then column side face is worn into the bottom surface of semicircle sphere as bulb together with the cork layer, also promptly with the contact-making surface of racket, in the process except that shape and size will meet the requirements, also to count heavily, with the bulb weight that guarantees the finished product shuttlecock is half that ball weighs just, the bulb base of making is shape after testing, size, after weight all meets the requirements, wrap one deck PU skin again, require to be close to bulb base bottom surface, do not peel, surface is pure white, and unnecessary PU skin is cut away along bulb base end face, continue to use 16 holes of the even ground auger of special machine at bulb base end face along circumferential edge then, pitch-row PU skin generally is not less than 0.01mm, in order to avoid ceasma, so far, finish each procedure in the bulb production technology.

Introduce the production technology of workprint now, with reference to Fig. 1, the workprint production technology is made up of buying and collection, the processing of workprint, the screening and the classification three process of workprint of goose feather.The inventor is by to the further investigation of pterylology, find goose feather exist aberration, stalk poor, curved poor, bend that poor, potential difference, thread poor, the method for double differences, elastic force are poor, shape differs from nine kinds of difference.Aberration is the difference of goose feather color and luster; Stalk difference refers to that the thick thickness of doing in the middle of the goose feather is hard soft poor; Curved difference refers to the difference that a hair stalk left side is curved or the right side is curved, and right the bending of the curved left wing in a right wing left side is goose physiological law only; The bow difference refers to the upwards curved or decurved difference of hair stalk; Potential difference refers to the difference of goose feather diverse location on wing, from first of goose wing afterbody to the end near the 27th of body, the lousiness of every goose feather all forms different angles of inclination with the hair stalk, have only the 1st to the 4th requirement that just meets the GB shuttlecock, and preceding 2 is the one-level hair, back two more relatively poor, therefore, every goose can only be gathered 8 hairs at most, each 4 of promptly left and right wings; The silk difference is lousiness thickness density length poor of goose feather; The method of double differences refers to the difference of goose feather weight; The elastic force difference mainly refers to the elasticity of hair stalk, the i.e. difference of antifatigue degree; The shape difference refers to the difference of goose feather shape size.Because workprint is processed by goose feather, therefore workprint also has above-mentioned nine kinds of difference, select for use the workprint of nine kinds of difference unanimities to be assembled into same ball, it is the material base that can axis, center of gravity line, the interior air-flow post three of this ball coincide, therefore, the workprint production technology of this Quality Control method is carried out quality control to the collection and the buying of goose feather at first exactly.The further investigation of inventor by goose is raised, find same kind, same goose age, same natural surroundings, same feeding and management and feed condition, nine kinds of difference of hair of the goose chief of same health degree are approaching substantially, and nine kinds of difference of hair of the different goose chief of above-mentioned all conditions obviously increase, therefore, in the goose feather gatherer process, it must be same kind, same goose age, same natural surroundings, same feeding and management and feed condition, the hair that the goose of same health degree is cut could be formed with a collection of hair, then the goose feather of being gathered is processed into workprint respectively by different batches, at last to every batch of qualified workprint that is processed into by nine kinds of difference consistent grouping management that carries out whether, promptly every batch of workprint is divided into some groups again, its aberration of workprint on the same group, it is poor to obstruct, curved poor, it is poor to bend, silk is poor, potential difference, the method of double differences, elastic force is poor, the shape difference is basic identical.

Introduce now and urge into device packaging technology, as shown in Figure 1, urge into the device packaging technology to form by assembling workprint, hook coil, the glue three process of reaching the standard grade.With reference to Fig. 2, shuttlecock is by bulb 1 and urge into device two parts to form, and urges into device to be made up of 16 workprints 4 and upper and lower twice coil 5,6.Earlier inject glue in 16 holes of bulb end face during assembling, in workprint patchhole successively, require to accomplish then: a. selects workprint on the same group for use; B. urging into, the hair stalk top of device 16 workprints suitable for reading will surround 360 ° of circles; C. the hair stalk is wanted evenly with the spacing of hair stalk, and the size of each air inlet window 2 just can be the same, and air inflow just can be balanced; D. the workprint with the lousiness part is critical by workprint, crack, air tight not, and angle 3 will equate for same ball, for not same ball, the width of the angle 3 visual workprints of workprint and workprint is adjusted in 15 °～25 ° scopes, can be decided to be 25 ° when workprint is narrower, the workprint of medium-width can be decided to be 20 °, the workprint of broad can be decided to be 15 °, by adjustment, make the resistance of in-flight rotational velocity of shuttlecock that the workprint of different in width makes and air-flow basic identical to corner dimension.Workprint assembling finish treat that glue is done after, be that available special-purpose hook line machine hook upper track coil 5 reaches road coil 6 down, the position of upper track coil can be done suitable adjustment up and down, urge on the device into the size of bore to make meeting the requirements so that adjust, can the adjusted bore of going up keep 360 ° of circles, whether balanced closely related with the elasticity of 16 workprints, the position of following road coil is greatly about 1/2nd places of upper track coil to the bulb end face.The twice coil position glue of determining can to reach the standard grade after good is finalized the design to urging into device; the performance of the glue that requirement is selected for use can reach anti-non cold embrittlement; temperature resistance is not soft; bonding strength is preferably arranged; could guarantee good typing effect and bonding intensity; glue will divide to be gone up to coil for three times; to guarantee the uniformity of gluing; and can prevent glue " removal of home " and stick on hair stalk or the lousiness; whenever gone up and all will count weight after a glue is waited to do shuttlecock; to adjust the amount of gluing next time, adjust with this and to urge the into weight of device, make it equal heavy half of ball just.Next process pastes bulb adhesive tape 7 exactly and further reinforces bulb, at last trade mark label is being urged the into centre of device endosphere crown face, and the production technology of so far whole grain ball all finishes, and then per 12 balls is dressed up one, and warehouse entry is for sale.
