[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] like Figures 1 to 4 , Figure 6As shown, a preparation device for worsted wool reflective yarn according to an embodiment of the present invention comprises a device base 1; a melting box 11 is fixedly connected to the device base 1, and a first through hole is provided in the middle of the melting box 11; a heater 12 is fixedly connected to the outer wall of the melting box 11; a servo motor 13 is fixedly connected to the top outer wall of the device base 1; a first wheel shaft 14 is fixedly connected to the output end of the servo motor 13; a second wheel shaft 15 is rotatably connected to the top outer wall of the device base 1 and close to the servo motor 13 , the No. 1 axle 14 and the No. 2 axle 15 are connected by a No. 1 belt; the No. 3 axle 16 is rotatably connected to the outer wall of one end of the device base 1, the No. 2 axle 15 and the No. 3 axle 16 are connected by a No. 2 belt, the No. 4 axle 18 is rotatably connected to the outer wall of the other end of the device base 1, and the No. 1 axle 14 and the No. 4 axle 18 are connected by a No. 3 belt; the No. 1 limit plate 17 is threadedly connected to the No. 3 axle 16; the No. 2 limit plate 19 is threadedly connected to the No. 4 axle 18;When preparing the worsted wool reflective yarn, firstly, two TEC treated 30-count Merino ultrafine wool and a reflective yarn are selected, and the two wools and the reflective yarn are paralleled by a paralleling machine, and then the yarn after paralleling is twisted by a double twisting machine, and the twist is designed to be 200S. Then, the yarn after double twisting is waxed. Waxing is used to reduce the friction between the yarn and the machine during the textile process and reduce the occurrence of broken ends. After waxing, the yarn is placed in a balanced room and placed in an environment of 30℃ / 80%RH for 1 2 hours, and finally the worsted wool reflective yarn is taken out for packaging. When waxing the worsted wool reflective yarn, the wax is first placed inside the melting box 11, and then the heater 12 is operated to heat and melt the wax inside the melting box 11 into wax liquid, and the wax liquid overflows the No. 1 through hole. During the waxing process, it is necessary to add broken wax regularly to ensure that the wax liquid is located above the No. 1 through hole. Both ends of the No. 1 through hole of the melting box 11 are equipped with seals, which are not shown in the figure. The seals are used to prevent the wax liquid from overflowing at both ends of the No. 1 through hole. , place the yarn disc with yarn on the No. 3 wheel axle 16, and use the No. 1 limit plate 17 to fix the yarn disc with yarn on the No. 3 wheel axle 16, fix the empty yarn disc on the No. 4 wheel axle 18 through the No. 2 limit plate 19, draw out the yarn from the yarn disc on the No. 3 wheel axle 16, pass the yarn through the No. 1 through hole and fix it on the yarn disc at the No. 4 wheel axle 18, as the output end of the servo motor 13 on the device base 1 drives the No. 1 wheel axle 14 to rotate, the No. 1 wheel axle 14 synchronously drives the No. 2 wheel axle 14 through the No. 1 belt and the No. 3 belt respectively. The shaft 15 and the fourth wheel shaft 18 rotate, and the second wheel shaft 15 drives the third wheel shaft 16 to rotate through the second belt. The outer wall of the yarn pulled through the first through hole can be evenly covered with wax liquid, and the excess wax liquid will be scraped off by the seal. After the yarn is pulled out of the melting box 11, the wax liquid solidifies due to the drop in temperature and adheres to the yarn. Finally, the waxed yarn is rolled up on the yarn disk at the fourth wheel shaft 18, replacing the waxing method of squeezing the yarn with crushed wax. By wrapping the yarn with wax liquid, the effect of evenly waxing the worsted wool reflective yarn can be improved. ;

The cooling box 2 is fixed to the front end of the melting box 11, and the yarn passes through the No. 1 guide cylinder 22 and the No. 2 through hole in advance. The No. 1 guide cylinder 22 guides the yarn to enter the No. 2 through hole. The refrigerator 21 works to cool and send cold air to the No. 2 through hole of the cooling box 2. The cold air cools the yarn passing through the cooling box 2. After the cooled yarn enters the melting box 11, it can not only reduce the occurrence of breakage caused by the high temperature of the wax liquid, but also quickly cool the wax liquid to wax the yarn, thereby improving the effect of waxing the yarn.

[0039] like Figure 1 , Figure 3 , Figure 4 and Figure 8As shown, a heat conductive sheet No. 1 is fixedly connected to the heater 12, and the end of the heat conductive sheet No. 1 away from the heater 12 is located below the metal plate 34; a heat conductive sheet No. 2 41 is fixedly connected to the bottom end of the metal plate 34, and the heat conductive sheet No. 2 41 is slidably connected to the inner wall of the heat conductive sheet No. 1 4; when scraping wax on the outer wall of the wax block 32, one end of the heat conductive sheet No. 1 4 is fixed to the heater 12, and the other end is fitted with the heat conductive sheet No. 2 41. As the heater 12 is working and heating, part of the heat is conducted to the metal plate 34 through the heat conductive sheet No. 1 4 and the heat conductive sheet No. 2 41, and then conducted to the metal scraper 36 by the metal plate 34. The heated metal scraper 36 can improve the wax scraping effect on the outer wall of the wax block 32.

[0040] like Figures 1 to 3 , Figure 6 As shown, a No. 1 gear rod 5 is rotatably connected to the base 1 of the device and located below the melting box 11; a wheel disc 51 is fixedly connected to the No. 1 gear rod 5, and the No. 4 wheel axle 18 is connected to the wheel disc 51 through a No. 4 belt; a No. 2 gear rod 52 is rotatably connected to the bottom end of the melting box 11, and the bevel gear on the No. 1 gear rod 5 can mesh with the bevel gear on the No. 2 gear rod 52; a main gear 53 is fixedly connected to the No. 2 gear rod 52; sub-gears 54 are rotatably connected to the four corners of the bottom end of the melting box 11, and the four sub-gears 54 can mesh with the main gear 53; the four sub-gears 54 are fixedly connected to the There is a stirring blade 55, and the stirring blade 55 is located inside the melting box 11; when part of the wax on the wax block 32 is scraped off into the melting box 11, the No. 4 wheel shaft 18 rotates with the output end of the servo motor 13, and synchronously drives the wheel 51 connected by the No. 4 belt to rotate, and the wheel 51 synchronously drives the bevel gear on the No. 1 gear rod 5 and the bevel gear on the No. 2 gear rod 52 to engage and rotate with each other, and the main gear 53 drives multiple sub-gears 54 to rotate synchronously with the No. 2 gear rod 52, and each sub-gear 54 drives the stirring blade 55 to stir the melted wax liquid inside the melting box 11, thereby increasing the melting speed of the scraped wax on the wax block 32.

The melted wax liquid penetrates into the interior of the protective tube 6 through multiple No. 1 through holes 61 to evenly wax the yarn. The protective tube 6 blocks the broken wax that falls into the melting box 11, and reduces the shaking caused by the multiple stirring blades 55 stirring the melted broken wax. The waxed yarn is scraped when passing through the scraper 63 inside the blocking block 62, reducing excessive wax adhesion on the yarn. Multiple No. 2 through holes 64 introduce air into the protective tube 6 outside the melting box 11, so that the yarn reaching the No. 2 through holes 64 can be quickly cooled. Finally, the cooled yarn is guided by the No. 2 guide tube 65 to the yarn reel for winding, which plays a role in evenly waxing the yarn and scraping off excess wax layer.

[0044] like Figures 1 to 9 As shown, a method for preparing worsted wool reflective yarn is provided, wherein the method adopts the worsted wool reflective yarn preparation device described above for production, and the method comprises the following steps:

[0045] S1: First, two chlorinated Merino superfine wools and a reflective yarn are selected, and the two Merino superfine wools and the reflective yarn are combined by a doubling machine to form a yarn, and then the rotation and twisting of the yarn are controlled by a doubling machine to achieve twisting of the yarn;

[0046] S2: Then, the two-for-one twisted yarn is waxed, and the two-for-one twisted yarn disc is placed on the third wheel axle 16. The yarn is drawn out and passes through the first guide cylinder 22, the cooling box 2, the melting box 11, the protective cylinder 6, and the second guide cylinder 65 to be connected to the yarn disc installed on the fourth wheel axle 18. Crushed wax is added into the melting box 11 and melted by heating with the heater 12. As the output end of the servo motor 13 drives the third wheel axle 16 and the fourth wheel axle 18 to rotate and pull the yarn, the yarn is cooled in the cooling box 2 and then enters the melting box 11 to be coated with wax liquid. The wax liquid quickly adheres to the cooled yarn and solidifies until the waxed yarn is pulled out and wound on the yarn disc at the fourth wheel axle 18.

[0047] S3: The waxed yarn is then placed in a balancing room to adjust the moisture content and regain of the yarn. After the adjustment is completed, it is transported for packaging, and multiple yarn reels are loaded into paper tubes. After packaging, it is sent to a warehouse for storage to complete the preparation of the worsted wool reflective yarn.

The No. 1 elastic member 35 squeezes the metal plate 34 to slide on the fixed rod 33 to fit closely to the outer wall of the wax block 32. The scraped wax falls into the melting box 11 for continuous waxing and melting. The wheel 51 drives the No. 1 gear rod 5 The bevel gear meshing with the bevel gear on the No. 2 gear rod 52 rotates, and the main gear 53 drives multiple meshing sub-gears 54 to rotate. Multiple stirring blades 55 stir the wax liquid and crushed wax in the melting box 11 to accelerate melting and mixing.
