[0002] Spray printing machines have the function of fixing patterns during the knurling process of velvet products. The quality of the spray printing performance determines the quality and style of the velvet fabric after spray printing. Traditional methods rely on natural gas or resistance wire to heat air or steam, and spray fixed patterns onto the fabric surface through small nozzles. However, the fabric patterns often have problems such as unclear layers and weak three-dimensionality.

[0003] There are currently no effective solutions to the problems in the relevant technologies.

[0004] Therefore, in order to solve the above problems, this utility model provides a spraying mechanism for a high-speed airflow finishing machine. Utility Model Content

[0025] The utility model will now be further described in conjunction with the accompanying drawings and specific embodiments:

[0026] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 According to an embodiment of the present invention, a spraying mechanism for a high-speed airflow finishing machine includes a blowing chamber 1 disposed inside the finishing machine, a spraying mechanism 2 mounted on the finishing machine, and a driving mechanism 3. The spraying mechanism 2 includes a front guide roller 21, a rear guide roller 22, and a spraying cylinder assembly mounted inside the finishing machine. The front guide roller 21 and the rear guide roller 22 are arranged in parallel, and the spraying cylinder assembly is disposed between the front guide roller 21 and the rear guide roller 22. The front guide roller 21, the rear guide roller 22, and the spraying cylinder assembly are arranged in a triangular pattern. The spraying cylinder assembly includes a spraying stationary cylinder 24 fixedly installed inside the finishing machine. The spraying mechanism 2 includes a spraying moving cylinder 25 installed inside the spraying stationary cylinder 24, and a nozzle 26 installed outside the spraying stationary cylinder 24. The nozzle 26 is a rotating air knife with an automatic rotation function when airflow passes through it. The drive mechanism 3 drives the spraying moving cylinder 25 to move, which is used to adjust the air outlet gap and air outlet time of the spraying stationary cylinder 24 and the spraying moving cylinder 25. One end of the spraying mechanism 2 is connected to an external natural gas heating mechanism for spraying only. The airflow first passes through the spraying moving cylinder C25 and rotates inside the spraying stationary cylinder C24 to the air outlet slot, then passes through the nozzle C26, and finally sprays onto the rough surface to form a random and irregular rotating flower pattern.

[0027] Please see Figure 1 The blowing chamber 1 is divided into upper and lower blowing chambers, which are evenly arranged inside the wool finishing machine. The main body of the spraying mechanism 2 is installed on the fixed frame of the wool finishing machine by bolts and is located at the front or rear end of the blowing chamber 1. The spraying mechanism 2 is an airflow jet spraying mechanism. The blowing chamber 1 realizes airflow blowing and combing of the fabric, so that the root hair of the pile fabric is loose and straight, the layers are distinct, and the three-dimensional effect is strong. At the same time, it shortens the production line, reduces energy consumption, and saves energy.

[0028] Please see Figure 3 and Figure 4The spraying mechanism 2 also includes a fixed plate A28 and a fixed plate B29 mounted on the finishing machine. The two ends of the front guide roller 21 and the rear guide roller 22 are respectively connected to the fixed plate A28 and the fixed plate B29 by bolts through the bearing seat 23. The front guide roller 21 and the rear guide roller 22 provide support for the bottom of the fabric and prevent the nozzle airflow from deforming.

[0029] Please see Figure 2 and Figure 5 Both the fixed spraying cylinder 24 and the moving spraying cylinder 25 are provided with air slots. One end of the moving spraying cylinder 25 is equipped with a sprocket A27. The drive mechanism 3 includes a drive reduction motor 31 mounted on the finishing machine. A sprocket B32 is mounted on the drive reduction motor 31. The sprocket A27 and the sprocket B32 are connected by a chain drive. The drive reduction motor 31 drives the sprocket B32 to rotate. The sprocket B32 drives the sprocket A27 to rotate through the chain. As the sprocket A27 rotates, the moving spraying cylinder 25 moves intermittently to the air slot, which facilitates the subsequent formation of random and irregular rotating flower patterns.

[0030] The working principle of the spraying mechanism of a high-speed airflow finishing machine is as follows: During operation, the control system on the finishing machine controls the drive reduction motor 31 to rotate the sprocket B32, which in turn drives the sprocket A27 to rotate via a chain. This causes the spraying cylinder 25 to move intermittently to the air outlet. The airflow first flows through the spraying cylinder 25 and then through the spraying stationary cylinder 24, and then through the nozzle 26 with an automatic airflow rotation function, finally spraying onto the pile surface to form random, irregular rotating floral patterns. The high-speed airflow finishing machine blows and combs the fabric pattern with airflow, making the pile fabric pattern loose and straight, with distinct layers and a strong three-dimensional effect, while simultaneously shortening the production line, reducing energy consumption, and saving energy.

[0031] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
