Description

Technical Field

[0001] This utility model relates to the field of garment equipment technology, and in particular to a connector for a vortex texturing machine network nozzle. Background Technology

[0002] In the technological evolution of texturing machine network nozzle connectors, the applicant's prior patent CN 114717711B proposed an improved solution. This connector includes a ceramic plate and an outer frame. The top of the ceramic plate has an upper air hole extending through the height direction and a groove passing through the upper air hole. The bottom of the ceramic plate has an outwardly expanded upper air hole forming a first guide slope. The bottom surface of the outer frame has a support column and a lower air hole, with the upper and lower air holes arranged concentrically. A gap is maintained between the ceramic plate and the bottom surface of the outer frame. This design optimizes the airflow path through the sloped guide, alleviating to some extent the airflow impact problem of traditional right-angle air holes. However, in practical applications, it has been found that because the airflow is still mainly axially direct and lacks rotational momentum control, the improvement in the entanglement uniformity of the filament network nodes is limited. Simultaneously, shear turbulence is easily generated when the airflow accelerates between the air holes, leading to a decrease in air pressure utilization. Therefore, how to further enhance the swirl generation capability, reduce turbulent pulsation, and balance the velocity gradient between air holes based on the existing guide structure has become a pressing technical bottleneck. Utility Model Content

[0003] Purpose of the invention: The purpose of this utility model is to provide a connector for a vortex texturing machine network nozzle. By adding a spiral groove to the inner wall of the lower or upper air hole, the spiral groove forces the airflow to generate tangential momentum, so that the airflow forms a stable spiral jet in the gap between the ceramic pieces. The uniformity of the filament entanglement is improved by about 15% to 25% compared with the prior art.

[0004] Technical solution:

[0005] A connector for a swirl-type texturing machine network nozzle includes a ceramic plate and an outer frame that mates with the ceramic plate. The top of the ceramic plate has an upper air hole that extends through the height direction of the ceramic plate. The top of the ceramic plate also has a groove that extends along the length direction of the ceramic plate and passes through the upper air hole. The outer frame includes a bottom surface with multiple support columns that protrude from the bottom surface and can clamp the two ends of the ceramic plate in the width direction or the two ends in the length direction. The bottom surface also has a lower air hole that extends through the height direction of the bottom surface. There is a gap between the upper air hole and the lower air hole that communicates with the outside air. The inner wall of the lower air hole or the upper air hole is provided with a spiral groove.

[0006] Furthermore, only the inner wall of the lower air hole is provided with a spiral groove.

[0007] Furthermore, only the inner wall of the upper air hole is provided with a spiral groove.

[0008] Furthermore, the inner walls of both the lower and upper air holes are provided with spiral grooves, and the spiral grooves of the upper air hole rotate in the same direction as the spiral grooves of the lower air hole.

[0009] Furthermore, the upper air vent at the bottom of the ceramic tile expands outward on the side near the air inlet to form a first guide slope communicating with the upper air vent. The bottom surface of the outer frame corresponding to the lower air vent extends upward and close to the upper air vent to form an extended lower air vent. The protruding part of the bottom surface of the outer frame corresponding to the extended lower air vent expands outward along the direction close to the bottom surface on the side near the air inlet to form a second guide slope that can guide the airflow.

[0010] Furthermore, a spiral groove is provided on the inner sidewall of the first guide slope.

[0011] Furthermore, the inner wall of the lower air hole in the extension section is provided with a spiral groove.

[0012] Furthermore, the diameter of the lower vent is 0.8-0.85 times that of the upper vent.

[0013] Beneficial effects: By adding spiral grooves to the inner wall of the lower or upper air hole, the spiral grooves force the airflow to generate tangential momentum, so that the airflow forms a stable spiral jet in the gap between the ceramic pieces, and the uniformity of the filament entanglement is improved by 15% to 25% compared with the existing technology.

[0018] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Example 1

[0020] like Figure 1 , 2As shown, a connector for a vortex texturing machine network nozzle includes a ceramic plate 1 and an outer frame 2 that cooperates with the ceramic plate. The top of the ceramic plate 1 is provided with an upper air hole 3 that extends through the height direction of the ceramic plate. The top of the ceramic plate 1 is also provided with a groove 4 that extends along the length direction of the ceramic plate and passes through the upper air hole. The outer frame 2 includes a bottom surface 5. The bottom surface 5 is provided with a plurality of support columns 6 that protrude from the bottom surface and can cooperate to clamp the two ends of the width direction or the two ends of the length direction of the ceramic plate. The bottom surface is also provided with a lower air hole 7 that extends through the height direction of the bottom surface. There is a gap between the upper air hole 3 and the lower air hole 7 that communicates with the outside air. The inner wall of the lower air hole 7 or the upper air hole 3 is provided with a spiral groove 8.

[0021] The spiral grooves 8 on the inner walls of the lower air hole 7 and the upper air hole 3 force the airflow to move along a spiral trajectory through the groove walls, giving the airflow tangential momentum. This design breaks through the limitation of unidirectional airflow impact of the straight air holes in the previous patent (CN 114717711B), forming a rotating jet, enhancing the circumferential winding effect of the airflow on the filament bundle, and improving the uniformity of network node distribution by 15% to 25%.

[0022] In this embodiment, the inner walls of both the lower air hole 7 and the upper air hole 3 are provided with spiral grooves 8, and the spiral grooves of the upper air hole and the lower air hole rotate in the same direction. When the inner walls of both the upper and lower air holes are provided with spiral grooves rotating in the same direction, the airflow is initially swirled in the upper air hole and then guided by a secondary spiral when entering the lower air hole, resulting in superimposed swirling intensity. This dual swirling design can suppress the momentum attenuation of the airflow during transmission, reduce turbulent kinetic energy loss by more than 30%, and prolong the effect time of the swirling on the filament bundle, thereby improving the entanglement tightness.

[0023] Furthermore, the diameter of the lower vent is 0.8-0.85 times that of the upper vent.

[0024] Example 2

[0025] like Figure 3 , 4 As shown, the upper air vent at the bottom of ceramic plate 1 expands outward on the side near the air inlet to form a first guide slope 31 that communicates with the upper air vent. The bottom surface of the outer frame corresponding to the lower air vent 7 extends upward and close to the upper air vent to form an extended lower air vent 71. The protruding part of the bottom surface of the outer frame corresponding to the extended lower air vent 71 expands outward along the direction close to the bottom surface on the side near the air inlet to form a second guide slope 72 that can guide the airflow.

[0026] When the high-pressure airflow is ejected downward from the upper air hole 3, according to the Bernoulli effect, the high-speed airflow will generate a local negative pressure through the gap, thereby adsorbing the external ambient airflow. The outward expansion design of the first guide slope 31 and the lower air hole of the extension section provide a smooth inlet channel for the external airflow, avoiding flow separation caused by right-angle edges.

[0027] Furthermore, a spiral groove 8 is provided on the inner sidewall of the first guide slope 31.

[0028] The inner wall of the lower air hole 71 of the extension section is provided with a spiral groove 8.

[0029] When a spiral groove is provided on the inner wall of the first guide slope 31, the external airflow is simultaneously given tangential rotational momentum during the guiding process.

[0030] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
