Description

Technical Field

[0001] The utility model relates to the technical field of nozzles, in particular to an energy-saving nozzle for a cloth dyeing machine. Background Art

[0002] In a dyeing machine, in order to provide power for the cloth to circulate in the dyeing machine for dyeing, a nozzle is generally provided in the dyeing machine. The nozzle generally has an annular jet flow channel. When in use, a high-pressure water flow (generally dye liquid) is ejected from the jet flow channel, and the direction of the jet is inclined toward the forward direction of the cloth, so that the cloth is pushed forward by the jet ejected from the jet flow channel.

[0003] This type of nozzle is generally composed of two tubes, which are spaced apart to form the aforementioned inclined jet channel. For details, reference may be made to the nozzle disclosed in the utility model patent with announcement number CN209816470U, in which the guide cavity is equivalent to the aforementioned jet channel.

[0004] However, this type of nozzle still has disadvantages when used. When high-pressure water flows through the jet channel, it will generate a large pressure in the jet channel. Therefore, the jet channel will be expanded under this water pressure for a long time, causing the inner and outer side walls of the jet channel to expand away from each other, which will cause the jet channel to become wider. In this way, the impulse of the jet ejected from the jet channel will be reduced. Therefore, it is necessary to increase the power of the water pump to increase the water pressure so that the jet channel has sufficient water pressure (i.e. impulse) to push the cloth forward, which increases energy consumption. Utility Model Content

[0005] In order to solve at least one of the technical problems mentioned in the background technology, the purpose of the utility model is to provide an energy-saving nozzle for a dyeing machine.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] An energy-saving nozzle for a dyeing machine comprises a first tube body and a second tube body; one end of the first tube body is inserted into the second tube body to form an annular jet flow channel with the second tube body; and a guide cavity connected to the jet flow channel is formed between the first tube body and the second tube body; the guide cavity has a water inlet, and a plurality of convex ribs distributed along the circumference of the jet flow channel are provided in the jet flow channel, and the convex ribs extend along the length direction of the jet flow channel; a supporting ring is sleeved on the outer peripheral wall of the second tube body corresponding to the position of the jet flow channel, and a connecting piece is provided between the supporting ring and the convex rib, and in the assembled state, the inner side of the convex rib is fixed to the first tube body, and the outer side of the convex rib abuts against the outer peripheral wall of the jet flow channel under the locking of the connecting piece.

[0008] Preferably, the jet flow channel is arranged obliquely.

[0009] Preferably, the connecting member comprises a screw, which passes through the support ring and the peripheral wall of the second tube body in sequence and is threadedly connected to the convex rib.

[0010] Preferably, a first through hole is provided on the peripheral wall of the support ring, and a second through hole is provided on the peripheral wall of the second tube body; a screw hole is provided on the convex rib, and the screw passes through the first through hole and the second through hole in sequence and is threadedly connected with the screw hole.

[0011] Preferably, the nozzle further comprises an outer sleeve, which is sleeved on the outside of the first tube body to enclose the first tube body and the second tube body to form the guide cavity.

[0012] Preferably, the first tube body is provided with a first flange, and the second tube body is provided with a second flange; the two ends of the outer sleeve are respectively connected to the third flange and the fourth flange; in the assembled state, the outer sleeve is arranged between the first flange and the second flange, and the first flange is connected to the third flange, and the second flange is connected to the fourth flange.

[0013] Preferably, a sealing ring is provided between the first flange and the third flange, and / or a sealing ring is provided between the second flange and the fourth flange.

[0014] Preferably, the water inlet is arranged on the peripheral wall of the outer sleeve.

[0015] Preferably, the convex rib is integrally formed with the first tube body.

[0016] Compared with the prior art, the advantages of adopting this solution are:

[0017] In the present solution, a convex rib connected to the first tube body is provided in the jet flow channel, and a support ring is provided on the outside of the second tube body. The convex rib can play a tensile role on the first tube body located at the jet flow channel, thereby limiting the inward expansion of the first tube body; and the support ring plays a supporting role on the second tube body, limiting the outward expansion of the second tube body located at the jet flow channel, thereby restraining the jet flow channel from expanding and widening. When the water flows through the jet flow channel, there is sufficient water pressure to form an impact force to drive the cloth forward, thereby avoiding the problem of increasing the output power of the water pump due to the widening of the jet flow channel, which helps to save energy.

[0018] In addition, in this embodiment, the convex ribs can also play an anti-vortex role, reducing the formation of vortexes in the jet flow channel. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0024] In the following description, terms such as "inside", "outside", "up", "down", "left", "right", etc. that indicate directions or positional relationships are only used to facilitate the description of the embodiments and simplify the description, and do not indicate or imply that the referred device or element must have a specific direction, be constructed and operate in a specific direction. Therefore, it should not be understood as a limitation on the present invention.

[0025] See also Figure 1-4 As shown, this embodiment provides an energy-saving nozzle for a dyeing machine, comprising a first tube body 1 and a second tube body 2; Figure 2 As shown, one end of the first tube body 1 is inserted into the second tube body 2 to form an annular injection channel 10 with the second tube body 2. Preferably, the first tube body 1 and the second tube body 2 are coaxially arranged.

[0026] The jet channel 10 is inclined, and its inclination direction is gradually inclined toward the center of the first tube body 1 along the axial direction of the first tube body 1. In this way, the water flow injected by the jet channel 10 is inclined toward the axis of the first tube body 1 to generate thrust on the cloth and push the cloth forward.

[0027] Specifically, the outer peripheral wall of the end side of the first tube body 1 is a conical surface, and the portion of the second tube body 2 located on the opposite side of the conical surface is conical, so that an inclined injection channel 10 is formed between the conical surface of the first tube body 1 and the conical portion of the second tube body 2.

[0028] It can also be understood that the conical surface of the first tube body 1 constitutes the inner peripheral wall of the injection channel 10 , and the inner side wall of the conical portion of the second tube body 2 constitutes the outer peripheral wall of the injection channel 10 .

[0029] A guide cavity 30 connected to the jet flow channel 10 is formed between the first tube body 1 and the second tube body 2; the guide cavity 30 has a water inlet 33, and water (i.e., dye liquid) is drawn by a water pump and introduced into the guide cavity 30 through the water inlet 33. After the high-pressure water enters the guide cavity 30, it is ejected from the jet flow channel 10 to push the cloth forward.

[0030] The specific structure of the flow guide cavity 30 is as follows:

[0031] The nozzle further includes an outer sleeve 3, which is sleeved outside the first tube body 1 to enclose the first tube body 1 and the second tube body 2 to form the guide cavity 30. Specifically:

[0032] Combination Figure 2 and Figure 3 As shown, a first flange 12 is fixed on the outer peripheral wall of the first tube body 1 , and a second flange 21 is fixed on the upper end of the second tube body 2 .

[0033] The two ends of the outer sleeve 3 are respectively connected with the third flange 31 and the fourth flange 32; in the assembled state, the outer sleeve 3 is arranged between the first flange 12 and the second flange 21, and the first flange 12 and the third flange 31 are connected by bolts and nuts, and the second flange 21 and the fourth flange 32 are also connected by bolts and nuts.

[0034] The water inlet 33 is arranged on the peripheral wall of the outer sleeve 3 .

[0035] In order to improve the sealing performance of the flange connection, in this embodiment, a sealing ring 6 is embedded between the first flange 12 and the third flange 31 , and a sealing ring 6 is also embedded between the second flange 21 and the fourth flange 32 .

[0036] Combination Figure 2 and Figure 4 As shown, the jet channel 10 is provided with a plurality of convex ribs 11 distributed along the circumference of the jet channel 10 , and the convex ribs 11 extend along the length direction of the jet channel 10 ; the length direction here can also be understood as the extension direction of the jet channel 10 .

[0037] A support ring 4 is sleeved on the outer peripheral wall of the second tube body 2 corresponding to the position of the jet flow channel 10 (i.e., the tapered portion forming the position of the jet flow channel 10). The support ring 4 is an annular structure and is adapted to the tapered portion of the second sleeve 3. The function of the support ring 4 is to support the second tube body 2 at the position of the jet flow channel 10, and prevent the second tube body 2 from expanding outward due to the high-pressure water flow in the jet flow channel 10.

[0038] A connecting piece is provided between the support ring 4 and the convex rib 11 . In the assembled state, the inner side of the convex rib 11 is fixed to the first tube body 1 . Preferably, the convex rib 11 is integrally formed with the first tube body 1 , that is, the convex rib 11 is formed on the conical surface of the first tube body 1 .

[0039] The outer side of the rib 11 abuts against the outer peripheral wall of the jet channel 10 when the connector is locked. After the rib 11 is connected by the connector, it can restrain the first tube body 1 when the connector is locked, preventing the conical surface of the first tube body 1 from expanding inward due to the high-pressure water flow in the jet channel 10.

[0040] In addition, the presence of the convex rib 11 can also play an anti-vortex flow role, reducing the vortex flow formed in the injection flow channel 10 and rotating circumferentially around the injection flow channel 10.

[0041] The connecting member may be a screw 5, which passes through the support ring 4 and the peripheral wall of the second tube body 2 in sequence and is threadedly connected with the rib 11. Specifically:

[0042] like Figure 2 and Figure 3 As shown, a first through hole 41 is provided on the peripheral wall of the support ring 4, and a second through hole 22 is provided on the peripheral wall of the second tube body 2; a screw hole 111 is provided on the convex rib 11, and the screw 5 passes through the first through hole 41 and the second through hole 22 in sequence and is threadedly connected with the screw hole 111.

[0043] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
