Detailed Description

The invention is further described below with reference to the accompanying drawings.

As shown in figure 1, the anti-fake string bead head main body of the anti-fake string bead head is made of aviation aluminum pieces, the hardness of the aviation aluminum pieces is equivalent to that of copper, and the weight of the aviation aluminum pieces is lighter. The both ends terminal surface cover colour coating 1 of pearl head 4, and the colour coating 1 of this embodiment is the metal printing ink layer, the metal printing ink layer forms through the silk screen printing mode, and after the pearl head was neatly arranged according to the order, a plurality of pearl heads of disposable silk screen printing can improve production efficiency. The color of the ink layer can be various colors, such as a common black metal ink layer, a red metal ink layer, a pink metal ink layer, a blue metal ink layer, a purple metal ink layer, a green metal ink layer and the like; the color of the end surface of the bead head can be matched with strings with different colors, for example, the bead head of the red end surface can be matched with red strings, so that the whole color is richer; when the strings have no color, a beginner can hardly distinguish the line number of each string in the packaging bag, so that the six strings are difficult to be correctly arranged, and after the bead heads and the strings are wound, the line numbers of the strings can be distinguished through the colors of the end surfaces of the bead heads, if the packaging bag is marked with black, red, pink, blue, purple and green and respectively corresponds to 1, 2, 3, 4, 5 and 6 line numbers, under the condition, a user can distinguish the line numbers of the strings according to the colors; when the metal ink layer is black, the metal ink layer can form a sharp contrast with the white color of an aluminum piece, and fine numbers 1, 2, 3, 4, 5 and 6 formed on the black metal ink layer by laser marking can be clearly distinguished, so that the string line type can be distinguished.

The metal ink layer is provided with a groove 2 penetrating to the end face of the string bead head, the groove 2 is formed by laser marking, the shape of the groove 2 can form a word mark or a pattern, and the word mark or the pattern can be a trademark of a manufacturer, so that an anti-counterfeiting logo is formed. The diameter of the through hole 3 on the bead head is reduced to 1.5mm, the effective area of the end face of the bead head is increased, the marked logo can be distributed along the through hole in an arc shape, the area of the logo is increased, and consumers can recognize the logo more easily.

As shown in fig. 2, a transparent protective layer 5 is provided on the color coating, the transparent protective layer of the embodiment is formed by spraying mirror surface UV varnish, and the mirror surface UV varnish has the following characteristics: 1. high brightness; 2. excellent protective performance, acid and alkali resistance, oil resistance, water resistance and corrosion resistance; 3. good weather resistance and chemical resistance; 4. scratch resistance, high hardness and scratch resistance; 5. easy wiping and cleaning; 6. the curing speed is high.

As shown in FIG. 5, the method for manufacturing the anti-counterfeiting string ball head comprises the following steps:

(1) turning an aviation aluminum material to form a bead head;

(2) deburring and polishing the bead heads;

(3) cleaning and drying the bead heads;

(4) covering the end faces of the two ends of the bead head with a metal ink layer by silk-screen printing;

(5) drying the metal ink layer at the temperature of 100-120 ℃;

(6) marking the end surfaces of the two ends of the bead head by a laser marking machine to form a groove on the metal ink layer;

(7) spraying mirror surface UV gloss oil on the metal ink layer;

(8) and irradiating the end surface mirror surface UV gloss oil of the bead head by using a UV curing machine to cure the UV gloss oil to form a transparent protective layer.

In the step (2), the bead heads are polished in a cylinder polishing machine, and sawdust or chaff can be put into the cylinder without damaging the surfaces of the bead heads.

The specific method of the step (3) is as follows:

(3.1) putting the bead heads into a polishing agent 3188 for immersion cleaning, so that the surfaces of the bead heads are bright;

(3.2) putting the bead heads into clear water for cleaning;

(3.3) putting the bead heads into a release agent for immersion washing;

(3.4) putting the bead heads into clear water for cleaning;

and (3.5) drying the bead heads.

The surface brightness of the cleaned bead head is higher, and the bead head is in sharp contrast with a metal ink layer, and particularly, the display effect of the groove logo is enhanced by the black metal ink layer.

In the step (4), as shown in fig. 3 and 4, the bead heads need to be shaped and arranged by using a fixture before silk-screen printing on the bead head end surfaces, the fixture comprises a metal plate 6, a plurality of equidistant and parallel-arranged limiting grooves 8 are formed in the metal plate 6, an introduction groove 7 communicated with the limiting grooves 8 is formed in one end of each limiting groove 8, the width of each limiting groove 8 is smaller than the diameter of the end surface of each bead head 4, and the width of each introduction groove 7 is larger than the diameter of the end surface of each bead head 4; the bead head 4 enters the limiting groove 8 from the leading-in groove 7, and the limiting groove 8 clamps the circumferential surface of the bead head 4, so that the end surfaces of the two ends of the bead head are exposed at the two sides of the metal plate 6. During silk-screen printing, the metal plate 6 is vertically placed, the end faces of the two sides of the bead heads 4 are subjected to silk-screen printing through the silk-screen mesh cloth 9, and a metal ink layer can be subjected to silk-screen printing through manual or automatic equipment.

The specific marking method in the step (6) comprises the following steps:

(6.1) putting the silk-screen bead heads into a vibration disc;

(6.2) the bead heads are orderly arranged and output through a vibrating disk, and the end faces of the bead heads are upward;

(6.3) the bead heads are arranged in order and conveyed to a laser marking machine, and the marking head marks the end faces of the arranged bead heads in sequence;

and (6.4) automatically blanking the marked bead heads.

In the step (7), 20 ~ 35% alcohol is added into the mirror surface UV gloss oil, and then the mirror surface UV gloss oil is sprayed on the metal ink layer through a spray gun.

The end face of the string bead head is covered with the color coating as the bottom lining, then the color coating is provided with the groove penetrating to the end face of the string bead head, the color of the end face of the bead head can be seen through the groove, the two colors form bright contrast, the anti-counterfeiting word mark or the pattern formed by the groove can be more prominent, and the anti-counterfeiting word mark or the pattern can be more easily recognized by a consumer; the color coating is arranged on the end face of the bead head, and the winding of the string cannot be scraped to the color coating; in addition, a transparent protective layer is added on the color coating, so that the color coating can be protected and can be completely stored for a long time; the string ball head is usually sold after being wound with a string, and the anti-counterfeiting effect of the string is indirectly achieved through the anti-counterfeiting effect of the ball head.
