Description

Technical Field

[0001] The utility model relates to a nozzle, in particular to an adjustable nozzle for a dyeing machine, belonging to the technical field of dyeing and finishing equipment. Background Art

[0002] For different fabric varieties, in order to avoid the drawbacks of rope-like dyeing such as scratches, creases, chicken claw marks, color difference or color mottle during the dyeing process, the general method is to replace nozzles with different gaps to adjust the water flow pressure. A variety of nozzles with fixed gap specifications are needed for production use. This method requires replacing nozzles with the required gap specifications, which is a cumbersome process and has high production costs. Utility Model Content

[0003] In order to solve the above problems, a single nozzle is used to replace the nozzles that previously required multiple fixed gap specifications by changing the gap, so as to solve the problems of cumbersome replacement and high production cost in the past.

[0004] The utility model provides an adjustable dyeing machine nozzle, comprising a nozzle housing, an upper sealing ring, a nozzle head, a closed cavity, a nozzle body and a lower sealing ring; the nozzle head is provided with an upper groove corresponding to the upper sealing ring, and the upper sealing ring is embedded in the upper groove; the nozzle head is embedded in the nozzle housing, and the nozzle head is provided with a countersunk hole, a nozzle head rib plate and a gap rib plate; the nozzle housing is provided with a gap groove and a threaded hole corresponding to the nozzle head; the nozzle body is provided with a lower groove corresponding to the lower sealing ring, and the lower sealing ring is embedded in the lower groove, and the nozzle body is also provided with a clamping ring; the nozzle housing is provided with a rib plate to support the nozzle body and a positioning hole corresponding to the nozzle body, and the nozzle body can be prevented from rotating by a positioning bolt; the gap groove of the nozzle housing can ensure that the nozzle head can adjust the nozzle gap between the nozzle head and the nozzle body within a certain range and is fixed by a bolt.

[0005] Furthermore, the nozzle housing, nozzle head, closed cavity and nozzle body are all made of 316L material.

[0006] Furthermore, the nozzle housing and the nozzle head are both provided with facing grooves and corresponding matching holes, and the nozzle gap between the nozzle head and the nozzle body can be adjusted by the stepped groove structure.

[0007] Compared with the prior art, the present invention has the following beneficial effects: the present invention accurately adjusts the nozzle gap between the nozzle head and the nozzle body through a stepped structure connection, thereby changing the nozzle pressure and greatly reducing the number of nozzles produced. The material of the nozzles is 316L, which can effectively prevent corrosion in environments where they are in contact with dye solution for a long time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0014] In order to understand the present invention more clearly, the following describes the specific implementation of the present invention in conjunction with the accompanying drawings.

[0015] like Figure 1-5 As shown, the utility model provides an adjustable dyeing machine nozzle, including a nozzle housing 1, an upper sealing ring 2, a nozzle head 3, a closed cavity 5, a nozzle body 18 and a lower sealing ring 11. The nozzle head 3 is provided with an upper sealing ring groove 13 corresponding to the upper sealing ring 2, and the upper sealing ring 2 is embedded therein to ensure that the dye liquid does not leak. The nozzle head 3 is provided with a sink hole 15, a nozzle head rib 14 and a gap rib 16; the nozzle body 18 is provided with a lower sealing ring groove 20 corresponding to the lower sealing ring 11, and the lower sealing ring 11 is embedded therein to ensure that the dye liquid does not leak. The clamping ring 19 is welded to the nozzle body 18, and four ribs 8 are welded inside the nozzle housing 1 to support the axial position of the nozzle body 18. The positioning bolts 12 can prevent the nozzle body 18 from rotating due to the impact of the water flow. The nozzle housing 1 is provided with a rib to support the nozzle body and a positioning hole 17 corresponding to the nozzle body. The positioning bolts can prevent the nozzle body from rotating.

[0016] By inserting gap rib 16 of nozzle head 3 into second gap groove 22 and then securing it with bolt 4 through threaded hole 26, nozzle gap 7 can be adjusted. By inserting gap rib 16 into different gap grooves (21-25) via stepped groove structure 6, the nozzle gap 7 can be adjusted to the corresponding value, thereby changing the nozzle pressure.

[0017] The working principle of the present invention is as follows: during operation, the dye liquid flows through the water inlet 9 and fills the entire closed cavity 5. As the cross-sectional area of ​​the water flows through the nozzle gap 7, a sharp decrease is caused, thereby generating nozzle pressure, and finally the water is ejected from the water outlet 10 in the form of a high-pressure liquid jet. The kinetic energy generated can drive the fabric to circulate and dye in the dyeing machine.

[0018] The present invention is not limited to the above-mentioned specific implementation methods. Without departing from the principle and spirit of the present invention, various changes and modifications can be made to the present invention, or some of the features therein can be replaced; all of which are within the technical solutions claimed to be protected by this patent.
