Description

Technical Field

[0001] This utility model belongs to the field of garment equipment technology, specifically relating to a ceramic sheet for a texturing machine network nozzle connector with a grooved protrusion structure. Background Technology

[0002] Network nozzles are one of the important components of spinning machines. Their function is to network the filament bundle to enhance the toughness of the filament, and they have been widely used in the spinning industry.

[0003] The ceramic network nozzles currently used in the industry still follow the technical framework of the 1990s and have two common defects: (1) rough airflow control: the traditional trough is a smooth channel with equal cross-section, the airflow is severely dissipated along the way, and the network uniformity is poor; (2) high yarn damage rate: the yarn slides and rubs against the trough wall over a large area, which leads to the proliferation of hair and the increase in the breakage rate. Utility Model Content

[0004] Purpose of the utility model:

[0005] In order to overcome the problems existing in the prior art, this utility model provides a ceramic plate for a texturing machine network nozzle connector with a grooved protrusion structure, which solves the problems of rough airflow control and high yarn damage rate in the prior art.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] A ceramic plate for a texturing machine network nozzle connector with a grooved protrusion structure is disclosed. The top of the ceramic plate has an upper air hole corresponding to the lower air hole, extending through the height of the ceramic plate. The top of the ceramic plate also has a groove extending along its length and passing through the air hole. The groove has at least one set of protrusions along its length. By setting the protrusions, friction of the yarn when contacting the sidewall of the groove is reduced. The shape and arrangement of the protrusions disrupt the smooth flow of airflow, making it easier to form vortices or turbulent zones between or behind the protrusions, which are conducive to network node formation. This more complex and powerful airflow dynamic can more effectively entangle and bind the filaments. The protrusions help to "support" the yarn near the central area where the airflow is more concentrated, allowing it to be more fully exposed to the network airflow, improving the efficiency and uniformity of network node formation. The presence of the protrusions physically prevents the yarn from completely adhering to the smooth groove wall (especially in the absence of airflow or under low tension), avoiding unnecessary friction and potential snagging.

[0008] Furthermore, the cross-sectional shape of the protruding structure along the length of the yarn groove is at least one of arc, trapezoid, triangle, or wave. Arc, triangle, and wave shapes can transform the line contact between the yarn and the yarn groove into point contact during yarn vibration. The trapezoidal structure can also reduce the length of the line contact. This significant reduction in contact area directly lowers the sliding friction resistance of the yarn as it passes through the yarn groove. This is particularly important for high-speed texturing machines, effectively reducing tension fluctuations and breakage rates. Smaller friction and contact area mean less physical damage to the yarn surface, reduced fuzzing, and better yarn strength retention.

[0009] Furthermore, the protruding structure has a continuous wavy cross-section along the length of the groove, with the troughs trapping air to form a micro-lubricating film, reducing contact pressure and eliminating yarn scratches; the non-abrupt contour ensures uniform stress distribution and improves the service life of the ceramic tile.

[0010] Furthermore, the cross-section of the protruding structure along the length of the groove is an arc, trapezoid, or triangle arranged at equal intervals along the length of the groove. The arc-shaped guide surface allows for a smooth transition of airflow, minimizing energy loss and generating stable, orderly vortices; the flat top surface of the trapezoidal structure provides a larger limiting support area, suppressing yarn bounce; the arc-shaped structure ensures a smooth transition when in contact with the yarn, avoiding sharp edges from cutting the yarn; the sharp apex of the triangular structure cuts through the airflow like a "knife," generating a strong, bidirectionally symmetrical vortex street, but it is essential to ensure that the radius of the apex rounded corner is ≤ the diameter of the yarn filament (usually <0.05mm), and to perform mirror polishing to reduce yarn damage.

[0011] Furthermore, the raised structure covers all circumferential directions of the radial cross-section of the groove.

[0012] Furthermore, the ceramic tile has an air guide groove at the bottom of the groove, and the bottom of the upper air hole is located at the upper end of the air guide groove. External airflow is introduced through the air guide groove, which is more energy-efficient.

[0013] Furthermore, the width of the groove at the rear end of the upper air hole is expanded outward, and a protruding structure is provided in the groove at the front end of the upper air hole. The expansion of the rear groove makes it easier for the airflow entering the groove from the upper air hole to move towards the rear end under the action of Bernoulli's principle, that is, to move along the conveying direction of the line, which is more energy-efficient. Since the groove at the front end is narrower, the line is more likely to collide with the groove here during conveying. Therefore, a protruding structure is provided in the groove at the front end.

[0014] Furthermore, a raised structure is also provided in the groove at the rear end of the upper air hole. Since the rear groove is wider, the collision between the wire and the groove wall is relatively less frequent. Whether or not to set this structure can be considered according to actual needs.

[0015] A connector for a texturing machine network nozzle includes the aforementioned ceramic piece.

[0016] A texturing machine network nozzle includes the aforementioned connector.

[0017] Beneficial effects: Compared with the prior art, the present invention has the following advantages: By setting the protruding structure, the friction of the yarn when it contacts the side wall of the groove is reduced. The shape and arrangement of the protrusions will disrupt the smooth flow of airflow and make it easier to form vortices or turbulent zones between or behind the protrusions that are conducive to the formation of network nodes.

[0025] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0026] This specification includes any feature disclosed in any appended claims, abstract, and drawings, which, unless specifically stated otherwise, may be replaced by other equivalent or similar features. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Example 1

[0029] like Figure 1-3As shown, a ceramic plate for a texturing machine network nozzle connector with a grooved protrusion structure is provided. The top of the ceramic plate 1 has an upper air hole 2 that extends through the height of the ceramic plate, corresponding to the lower air hole. The top of the ceramic plate 1 also has a groove 3 extending along the length of the ceramic plate and passing through the air hole. The groove 3 has at least one set of protrusions 4 along its length. By setting the protrusions, the friction of the yarn when contacting the sidewall of the groove is reduced. The shape and arrangement of the protrusions disrupt the smooth flow of airflow, making it easier to form vortices or turbulent zones between or behind the protrusions, which are conducive to the formation of network nodes. This more complex and powerful airflow dynamic can more effectively entangle and bind the filaments. The protrusions help to "support" the yarn near the central area where the airflow is more concentrated, allowing it to be more fully exposed to the network airflow, improving the efficiency and uniformity of network node formation. The presence of the protrusions physically prevents the yarn from completely adhering to the smooth groove wall (especially in the absence of airflow or under low tension), avoiding unnecessary friction and potential snagging.

[0030] Furthermore, the protruding structure 4 has a continuous wavy cross-section along the length of the groove 3. The troughs trap air to form a micro-lubricating film, reducing contact pressure and eliminating yarn scratches. The non-abrupt contour ensures uniform stress distribution and improves the service life of the ceramic tile.

[0031] Furthermore, the cross-section of the protruding structure 4 along the length of the groove 3 is an arc, trapezoid, or triangle arranged at equal intervals along the length of the groove 3. The arc-shaped guide surface allows for a smooth transition of airflow, minimizing energy loss and generating stable, orderly vortices; the flat top surface of the trapezoidal structure provides a larger limiting support area, suppressing yarn bounce; the arc-shaped structure ensures a smooth transition when in contact with the yarn, avoiding sharp edges from cutting the yarn; the sharp apex, like a "knife," cleaves the airflow, generating a strong, bidirectional symmetrical vortex street, but it must be ensured that the radius of the apex rounded corner is ≤ the diameter of the yarn filament (usually <0.05mm), and it must be mirror-polished to reduce yarn damage.

[0032] Furthermore, the raised structure covers all circumferential directions of the radial cross-section of the groove.

[0033] Furthermore, the ceramic tile has an air guide groove 5 at the bottom of the groove, and the bottom of the upper air hole 3 is located at the upper end of the air guide groove 5. External airflow is introduced through the air guide groove, which is more energy-efficient.

[0034] Example 2

[0035] like Figure 4 As shown, the protruding structure 4 has an arc-shaped cross-section along the length of the groove 3. The arc-shaped guide surface allows for a smooth transition of airflow, resulting in minimal energy loss and generating a stable and orderly vortex.

[0036] Example 3

[0037] like Figure 5 As shown, the cross-sectional shape of the protruding structure 4 along the length of the groove 3 is triangular; the sharp vertex of the triangular structure cuts through the airflow like a "blade", generating a strong vortex street with bidirectional symmetry, but it is necessary to ensure that the radius of the vertex round corner is less than or equal to the diameter of the yarn filament (usually less than 0.05 mm), and to perform mirror polishing to reduce damage to the yarn.

[0038] Example 4

[0039] like Figure 6 As shown, the cross-sectional shape of the protrusion structure 4 in the length direction of the groove 3 is trapezoidal. The flat top surface of the trapezoidal structure provides a larger limiting support area and suppresses yarn jump. The arc structure ensures a smooth transition when in contact with the yarn, avoiding sharp edges from cutting the yarn. The two apex corners of the trapezoidal structure are chamfered and polished.

[0040] Example 5

[0041] like Figure 7 As shown, the width of the groove 3 located at the rear end of the upper air hole 2 is expanded outward, and a protruding structure 4 is provided in the groove located at the front end of the upper air hole 2. The expansion of the rear groove makes it easier for the airflow entering the groove from the upper air hole to move towards the rear end under the action of Bernoulli's principle, that is, to move along the conveying direction of the line, which is more energy-efficient. Since the front groove is narrower, the line is more likely to collide with the groove during conveying. Therefore, a protruding structure is provided in the front groove.

[0042] Furthermore, a raised structure 4 is also provided in the wire groove located at the rear end of the upper air hole 2. Since the rear wire groove is wider, the collision between the wire and the wire groove wall is relatively less frequent. Whether to set it can be considered according to actual needs.

The purpose is to enable the public to have a more thorough and comprehensive understanding of the disclosed content of this utility model, and it is not intended to limit the protection scope of this utility model.

[0044] The above embodiments are not an exhaustive list based on the present invention, and there may be other embodiments not listed. Any substitutions and improvements made without departing from the concept of the present invention are within the protection scope of the present invention.
