Description

Technical Field

[0001] This utility model relates to the field of nozzle technology, specifically to a nozzle for precision wet treatment of textiles. Background Technology

[0002] Dyeing, also known as coloring, refers to the process of using chemical or other methods to influence the substance itself to make it colored. Under the conditions that allow technology, dyeing can make objects present various colors that people need, using colorful colors to decorate life. In order to improve dyeing efficiency, the method of using a nozzle to spray paint ink in a mist onto the material to be dyed can improve the dyeing effect. Therefore, the nozzle is a common device in the dyeing field.

[0003] When dyeing using a conventional spray nozzle, the front end of the nozzle is round. Therefore, during the dyeing process, the nozzle will carry the material outward in a circular pattern. This type of nozzle has a large spraying range, but during the spraying process, the spraying range spreads in a circular direction. When it is necessary to dye a neat surface, an auxiliary device is required to cover the areas that do not need to be sprayed before the spraying operation can be carried out. This results in low spraying efficiency because the workers need to cover the areas that do not need to be sprayed with a protective device during the spraying operation. Therefore, we propose a spray nozzle for precise wet treatment of textiles. Utility Model Content

[0004] To address the shortcomings of existing spray heads for precision wet treatment of textiles, this utility model provides a spray head for precision wet treatment of textiles. It features the advantage of spraying dye in a flat direction by using a baffle, and adjusting the spray angle by adjusting the handle, thereby improving the precision of spraying and solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a spray head for precision wet treatment of textiles, including a spray head body, a baffle fixedly connected to the front end of the spray head body, an adjustment handle movably sleeved on the outside of the baffle, a feed pipe installed at the rear end of the spray head body through a connecting sleeve, a gas flow pipe installed at the rear end of the feed pipe, and a conical plate fixedly connected inside the feed pipe.

[0006] Preferably, an atomizing device for driving liquid atomization is installed inside the nozzle body, and the atomizing devices are arranged at equal intervals inside the nozzle body.

[0007] Preferably, an arc-shaped plate is fixedly connected to the inner side of the adjustment handle, the inner side of the arc-shaped plate is arc-shaped, the outer side of the adjustment handle is installed at the outer center of the baffle by screws, and the arc-shaped plate is fitted to the inner wall of the nozzle body.

[0008] Preferably, a dye delivery pipe is fixedly connected to the lower part of the delivery pipe, a spray material box is installed on the outside of the dye delivery pipe, and an air pump is connected to the other end of the gas flow pipe.

[0009] Preferably, a gasket is fixedly connected to the external end of the feed pipe, and a tightening nut is movably sleeved on the external end of the gasket. The tightening nut is threaded on the external end of the feed pipe, and the inner side of the tightening nut is conical. The conical surface formed on the inner side of the tightening nut contacts the external end of the gasket.

[0010] Preferably, the outer part of the conical plate is conical, and the conical plate extends into the interior of the gas flow pipe.

[0011] Compared with existing spray nozzles for precision wet treatment of textiles, this utility model has the following advantages: 1. This precision wet treatment nozzle for textiles allows for adjustment of the spraying range within 120° to 180° by adjusting the position of the handle, i.e., adjusting the spraying range formed by the inner side of the baffle, i.e., adjusting the nozzle angle. Furthermore, the arc-shaped plate is fitted and installed on the inner side of the nozzle body, so the uniformity of spraying is not affected during the adjustment of its spraying angle.

[0012] 2. This precision wet treatment nozzle for textiles is installed inside the feed pipe via a gas flow tube. By rotating the tightening nut, the position of the gas flow tube is defined. Continuous rotation of the tightening nut increases the pressure applied to the gas flow tube, thus adjusting the distance the gas flow tube extends into the feed pipe. This changes the distance between the gas flow tube and the conical plate, and the conical plate becomes conical, altering the opening between the conical plate and the gas flow tube. Thus, by rotating the tightening nut, the spray volume can be adjusted. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A spray head for precision wet treatment of textiles includes a spray head body 1. A baffle 2 is fixedly connected to the front end of the spray head body 1. The baffle 2 is flat and can limit the spraying range. An adjustment handle 3 is movably sleeved on the outside of the baffle 2. The spraying angle can be controlled by adjusting the position of the adjustment handle 3. A feed pipe 7 is installed at the rear end of the spray head body 1 through a connecting sleeve 6. A gas flow pipe 9 is installed at the rear end of the feed pipe 7. The gas flow pipe 9 drives the gas to be output to the front end. A conical plate 12 is fixedly connected inside the feed pipe 7.

[0017] Please see Figure 3 The nozzle body 1 is equipped with an atomizing device 5 that drives the liquid to atomize. The atomizing devices 5 are arranged at equal intervals inside the nozzle body 1. When the high-pressure gas carries the dye into the nozzle body 1, it provides a barrier to the atomizing device 5, so that the material can form an atomized state. At the same time, the atomized dye is sprayed out through the baffle 2. The baffle 2 has a fan-shaped flat structure, which ensures the accuracy of the spraying after the dye is sprayed out through the baffle 2 and improves the spraying effect.

[0018] Please see Figure 2 and Figure 4 An arc-shaped plate 4 is fixedly connected to the inner side of the adjusting handle 3. The inner side of the arc-shaped plate 4 is arc-shaped. The outer side of the adjusting handle 3 is installed at the outer center of the baffle 2 by screws. The arc-shaped plate 4 is fitted against the inner wall of the nozzle body 1. The adjusting handle 3 is installed at the outer center of the baffle 2, and the arc-shaped plate 4 is fitted against the inner wall of the nozzle body 1. In the normal state, the adjusting handle 3 drives the arc-shaped plate 4 to move to a parallel state, that is, the dye is sprayed at 180°. Adjusting the angle of the arc-shaped plate 4, that is, the arc-shaped plate 4 drives the inner side of the baffle 2 to form a spray angle, can adjust the nozzle angle of the nozzle within the range of 120° to 180°.

[0019] Please see Figure 1A dye delivery pipe 8 is fixedly connected to the lower part of the conveying pipe 7. A spray material box is installed on the outside of the dye delivery pipe 8. An air pump is connected to the other end of the gas flow pipe 9. The spray material box is fixedly installed at the lower part of the conveying pipe 7. At the same time, an air pump is installed on the outside of the gas flow pipe 9. When the air pump is in use, it generates gas towards the front end. When the gas passes through the conveying pipe 7, it can drive the dye inside the spray material box of the dye delivery pipe 8 to be sprayed out together, thus driving the dye to perform dyeing treatment.

[0020] Please see Figure 5 A gasket 10 is fixedly connected to the external end of the feed pipe 7. A tightening nut 11 is movably sleeved on the external end of the gasket 10. The tightening nut 11 is threaded onto the external end of the feed pipe 7. The inner side of the tightening nut 11 is conical. The conical surface formed on the inner side of the tightening nut 11 contacts the external end of the gasket 10. It is installed at the rear end of the feed pipe 7 through the gas flow pipe 9. When the tightening nut 11 is rotated, the inner side of the tightening nut 11 applies pressure to the external end of the gasket 10. That is, the gasket 10 causes the gas flow pipe 9 and the feed pipe 7 to be tightly pressed together, thereby improving the stability of the gas flow pipe 9 when it is spliced.

[0021] Please see Figure 5 The outer part of the conical plate 12 is conical, and the conical plate 12 extends into the interior of the gas flow pipe 9. By rotating the tightening nut 11, the pressure applied by the tightening nut 11 to the gasket 10 is increased. At the same time, the tightening nut 11 adjusts the gap between the gas flow pipe 9 and the material conveying pipe 7. After the gas flow pipe 9 continues to move forward, the distance between the gas flow pipe 9 and the conical plate 12 changes. At the same time, the size of the space formed between the gas flow pipe 9 and the conical plate 12 can be adjusted. Thus, the amount of coating can be adjusted.

[0022] Working principle: In use, a spray material box is installed on the outside of the dye delivery pipe 8, and the gas flow pipe 9 is installed at the rear end of the delivery pipe 7. By rotating the tightening nut 11, the tightening nut 11 pushes the gasket 10 to move inward, that is, the gas flow pipe 9 is fixed at the rear end of the delivery pipe 7. By continuously rotating the tightening nut 11, the distance between the gas flow pipe 9 and the conical plate 12 is adjusted, and the spraying amount is adjusted. Depending on the spraying range, the spraying angle can be adjusted by rotating the adjustment handle 3. The gas is delivered to the inside of the delivery pipe 7 through the gas flow pipe 9, and at the same time, the gas drives the dye to be sprayed out. After being atomized by the atomizing device 5, the dye can be used for dyeing.
