[0002] Synthetic fibers are made of synthetic polymer compounds. Common synthetic fibers include polyester, nylon, acrylic, chloroprene, vinylon, spandex, polyolefin stretch yarn, etc. Synthetic fibers need to be processed by a variety of auxiliary equipment during processing. Yarn spraying is a surface treatment process. Compressed air is used as the power to form a high-speed jet beam to spray the material at high speed onto the surface of the fiber to be treated, so that the appearance of the fiber surface changes. Therefore, the yarn spraying device for synthetic fiber processing is indispensable.

[0003] The existing patent (publication number: CN208762613U) discloses a yarn spraying device for processing graphite tetrafluoro synthetic fiber, including a second return spring, a right guide wheel, a left guide wheel, a first return spring, an upper electric push rod, an upper arc plate, an upper nozzle, a lower arc plate and a lower nozzle. The second return spring is installed on the right side surface of the second guide groove, the right guide wheel is installed on the upper end of the second bracket, the left guide wheel is installed on the upper end of the first bracket, and the first return spring is installed on the left side surface of the first guide groove. The design realizes the precise guiding function of the fiber yarn. The upper electric push rod and the lower electric push rod are symmetrically arranged at the upper and lower parts of the central spray hole. The upper arc plate is fixed to the lower end of the upper electric push rod, the upper nozzle is installed on the lower surface of the upper arc plate, the lower arc plate is installed on the upper end of the lower electric push rod, and the lower nozzle is arranged on the upper surface of the lower arc plate. The design realizes the yarn spraying function of fiber yarns of different specifications. In the process of realizing the present utility model, the inventors found that the prior art has the following problems: 1. The sandblasting device will generate a large amount of harmful gases during the sandblasting process. The traditional sandblasting device cannot absorb these gases, resulting in some of the gases generated by the sandblasting being easily inhaled by nearby workers, which can easily cause certain harm to the workers' bodies over a long period of time; 2. The sandblasting heads of traditional sandblasting devices are mostly fixed structures. The fixed nozzles can only be fixed to sandblast one side of the synthetic fiber, and cannot spray yarn on other sides of the fiber, resulting in uneven yarn spraying on the fiber surface.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: a yarn spraying device for synthetic fiber processing, comprising a shell component 1 and two brackets 2, an exhaust fan 3 is arranged on the top of the shell component 1, an air collecting hood 4 is arranged on the inner top of the shell component 1, a collecting box 5 is arranged at one end of the shell component 1, a fixing seat 6 is arranged on the top of the two brackets 2, a sleeve 7 is arranged inside the two fixing seats 6 through a bearing, a plurality of nozzles 8 are arranged inside the sleeve 7, a plurality of connecting ports 9 are arranged on the outer side of the sleeve 7, an annular rack 10 is arranged on the outer middle part of the sleeve 7, a servo motor 11 is arranged on one side of the shell component 1, threaded rods 12 are arranged on the two inner walls of the shell component 1 through bearings, a threaded block 13 is arranged on the outer side of the threaded rod 12, a guide rod 14 parallel to the threaded rod 12 is penetrated through the inner top of the threaded block 13, and a rack 15 is arranged at the bottom end of the threaded block 13.

[0022] In this embodiment, Figure 1 As shown, the housing assembly 1 includes a base 101 , four corners of the bottom end of the base 101 are provided with support seats 102 , and a box body 103 is provided outside the top end of the base 101 .

[0023] In this embodiment, Figure 2 As shown, the wind collecting hood 4 and the exhaust fan 3 are connected to the collection box 5 through a connecting pipe, which realizes absorption of harmful gases generated during yarn spraying, solves the problem of the gas generated by sandblasting being emitted into the air and causing physical harm to the workers, thereby meeting the demand for yarn spraying for synthetic fiber processing.

[0024] In this embodiment, Figure 4 As shown, a plurality of nozzles 8 are equiangularly distributed inside the sleeve 7, so that the nozzles 8 can spray the surface of the synthetic fiber evenly, thereby greatly improving the spraying effect of the synthetic fiber.

[0025] In this embodiment, Figure 4 As shown, the central axis of the servo motor 11 is consistent with the central axis of the threaded rod 12; the consistent center lines can improve the stability of the rack 15 during movement, make the movement direction of the rack 15 single, and avoid the rack 15 from being offset during movement.

[0026] In this embodiment, Figure 3 As shown, the threaded block 13 and the guide rod 14 are provided with a sliding connection, which increases the stability of the threaded block 13 during movement, thereby preventing the threaded block 13 from rotating with the rotation of the threaded rod 12 .

[0027] In this embodiment, Figure 3 and Figure 4 As shown, the annular rack 10 and the rack 15 are arranged to be meshedly connected; the nozzle 8 is driven by the sleeve 7 to change its angle and position, thereby solving the problem of uneven spraying on the fiber surface because the nozzle 8 can only sandblast one side of the synthetic fiber, thereby greatly improving the spraying effect of the synthetic fiber.

[0028] The use method and advantages of the utility model: When the yarn spraying device for synthetic fiber processing is used, the working process is as follows:

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, first, the base 101 is placed at the designated position through the support seat 102, and then the external yarn spraying hose is connected to the connection port 9. When it is necessary to spray the synthetic fiber yarn, the servo motor 11 is started to drive the threaded rod 12 to rotate, and the threaded rod 12 drives the threaded block 13 to move under the limit of the guide rod 14. At this time, the threaded block 13 drives the rack 15 to move, and the rack 15 engages to drive the annular rack 10 to rotate, and the annular rack 10 drives the nozzle 8 to reciprocate through the sleeve 7 under the limit of the two fixed seats 6, so that the angle and position of the nozzle 8 are driven by the sleeve 7. The change solves the problem of uneven yarn spraying on the fiber surface because the nozzle 8 can only fix sandblasting on one side of the synthetic fiber, thereby greatly improving the yarn spraying effect of the synthetic fiber. At this time, the exhaust fan 3 is started to work, and the exhaust fan 3 absorbs the gas inside the box body 103 through the wind collecting hood 4. The absorbed yarn spraying gas is transported to the inside of the collecting box 5 through the connecting pipe, so as to absorb the harmful gas generated during the yarn spraying, and solves the problem of the gas generated by sandblasting being emitted into the air and causing physical harm to the staff, thereby meeting the yarn spraying requirements for synthetic fiber processing.

[0030] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected.
