Description

Technical Field

[0001] The utility model belongs to the technical field of clothing making equipment, and in particular relates to a plug-in connector for network nozzle accessories of a texturing machine. Background Art

[0002] The network nozzle is one of the important parts of the spinning machine. Its function is to network the filament bundle to enhance the toughness of the filament. It has been widely used in the spinning field.

[0003] The existing network nozzle accessories for texturizing machines adopt the conventional technology that has been used for 20 to 30 years and require the cooperation of high-energy air compressors. The current network nozzles form an overall structure by matching the ceramic tiles and brackets. The airflow of the air compressor enters the ceramic tiles through the vents on the bracket, and then networks the wires in the ceramic tile wire trough.

[0004] In view of the above problems, improvements have been proposed in the prior art, such as the applicant's previous application, and the publication number thereof is CN114717711B3. The specific content is a connector for a network nozzle accessory of a texturing machine, including a ceramic piece and an outer frame that cooperates with the ceramic piece. The top of the ceramic piece is provided with an upper air hole that penetrates the height direction of the ceramic piece. The top of the ceramic piece is also provided with a wire groove that extends along the length direction of the ceramic piece and passes through the upper air hole. The upper air hole at the bottom of the ceramic piece is expanded outward to form a first guide slope connected to the upper air hole. The outer frame includes a bottom surface, and the bottom surface is provided with a plurality of bracket columns 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 piece. The bottom surface is also provided with a lower air hole which runs through the height direction of the bottom surface. The upper air hole and the lower air hole are concentric along the transmission direction of the air flow. There is a gap between the bottom of the tile and the bottom surface of the outer frame. Through the coordination of the upper air hole, the lower air hole and the gap between the bottom of the tile and the bottom surface of the outer frame, when the air flow enters the lower air hole and reaches the upper air hole, the Bernoulli principle is used to form a negative pressure at the gap to attract external air flow to enter. At the same time, due to the existence of the first guide slope, the upper air hole can accommodate more air flow and increase the air flow speed at the upper air hole. In this way, the operating power of the air compressor can be reduced, thereby achieving the same preparation effect with lower energy consumption.

[0005] However, during actual use, it was found that during the process of inhaling external airflow, the airflow at the end of the wire trough would be inhaled. The flow direction of the airflow here is opposite to the direction of wire movement during the inhalation process, and the gap here is close to the outlet end of the wire trough, which will cause certain obstacles to the movement of the wire, resulting in limited energy consumption reduction during actual use. Utility Model Content

[0006] Purpose of the utility model:

[0007] In order to overcome the problems existing in the prior art, the utility model provides a connector for the network nozzle accessories of a texturizing machine.

At the same time, the air inlet of the air guide groove is set at one end in the direction of the ceramic piece, so that all the air enters from the air inlet close to the position of the wire groove inlet end. The flow direction of the external airflow at this end is the same as the conveying direction of the silk thread during the inhalation process, so that when the external airflow is inhaled, it can play a certain role in promoting the conveying of the silk thread, further reducing the overall energy consumption of the device.

[0008] In order to solve the above problems, the utility model adopts the following technical solutions:

The prior art uses the gap between the ceramic tile and the outer frame to introduce external airflow, but instead opens an air inlet at the bottom of the ceramic tile in the direction of the ceramic tile inlet to introduce external airflow through the air guide groove. At the same time, the air inlet of the air guide groove is provided at one end in the direction of the ceramic tile inlet, so that all of the air enters from the air inlet close to the inlet end of the wire trough.

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

[0026] Any feature disclosed in this specification, including any additional claims, abstracts and drawings, can be replaced by other equivalent or alternative features with similar purposes unless otherwise stated. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-3 As shown, in the first embodiment of the utility model, a connector for a network nozzle accessory of a texturizing machine includes a ceramic piece 1 and an outer frame 2 matched with the ceramic piece, a cavity for installing the ceramic piece is formed in the middle of the outer frame 2, and a lower air hole 7 penetrating the bottom surface height direction is also provided on the bottom surface of the outer frame, and an upper air hole 3 penetrating the height direction of the ceramic piece is provided at the top of the ceramic piece 1 corresponding to the lower air hole, and a wire groove 4 extending along the length direction of the ceramic piece and passing through the air hole is also provided on the top of the ceramic piece 1, and a circular groove with a diameter greater than the width of the wire groove is provided at the air hole of the wire groove, and the ceramic piece is provided with an air guide groove 5 at the bottom of the wire groove, and the bottom of the upper air hole 3 is provided at the upper end of the air guide groove 5, and an air inlet 6 is provided at one end of the air guide groove 5 close to the ceramic piece inlet direction, and an opening is provided at the position of the outer frame 2 corresponding to the air inlet.

[0029] An air guide groove is arranged at the bottom of the wire trough of the ceramic tile, and the bottom of the upper air hole is arranged at the upper end of the air guide groove. The prior art uses the gap between the ceramic tile and the outer frame to introduce external airflow, but instead uses an air inlet at the bottom of the ceramic tile to open an air guide groove in the direction of the ceramic tile inlet line to introduce external airflow. At the same time, the air inlet of the air guide groove is arranged at one end in the direction of the ceramic tile inlet line, so that all of them enter from the air inlet close to the inlet end of the wire trough. The flow direction of the external airflow at this end is the same as the conveying direction of the silk thread during the inhalation process, so that when the external airflow is inhaled, it can play a certain role in promoting the conveying of the silk thread, further reducing the overall energy consumption of the device.

[0030] Compared with the gap between the ceramic sheet and the outer frame in the prior art, the air guide groove is closer to the wire inlet of the wire trough and can better promote the transportation of the wire.

[0031] The exoskeleton does not need to be equipped with additional support columns to clamp the tiles. The tiles are directly installed on the bottom surface of the exoskeleton, which increases the overall firmness and simplifies the overall structure of the exoskeleton.

[0032] In this embodiment, the aperture of the lower air hole is 0.8 to 0.85 times the aperture of the upper air hole. With this structure, the airflow entering from the gap can be regarded as a reinforcement of the airflow in the lower air hole, and the airflow obtained in the upper air hole is the expected value. The pores in the upper air hole can accommodate more airflow, so the airflow loss will be reduced.

[0033] like Figure 4 As shown, in the second embodiment of the present utility model, the upper air hole opening located at the top of the air guide groove is expanded on one side close to the gap to form a first guiding inclined surface 31 communicating with the upper air hole.

[0034] In this embodiment, the bottom surface of the exoskeleton corresponding to the lower air hole 7 extends upward and close to the upper air hole to form an extended section lower air hole 71. Since a gap needs to be formed between the ceramic piece and the bottom surface of the exoskeleton, a gap needs to exist between the upper air hole and the lower air hole, but this gap cannot be extended indefinitely, so it is necessary to form an extended section lower air hole as close to the upper air hole as possible.

[0035] In this embodiment, the convex part of the bottom surface of the outer frame corresponding to the air hole in the extension section is expanded outward along the direction close to the bottom surface on one side close to the gap, forming a second guiding inclined surface 72 capable of guiding the airflow. The air hole is arranged in the second wire groove which is wider than the first wire groove, so that the air resistance encountered by the yarn in the wire groove is significantly reduced, thereby reducing the inclination angle of the air hole, increasing the strength of the network node, effectively reducing the air pressure consumption, and reducing the operating cost of the air compressor.

[0036] The purpose of the above embodiments is to exemplarily reproduce and deduce the technical solution of the utility model, and to fully describe the technical solution, purpose and effect of the utility model. Its purpose is to make the public understand the disclosed content of the utility model more thoroughly and comprehensively, and it does not limit the protection scope of the utility model.

[0037] The above embodiments are not exhaustive enumerations based on the present invention, and there may be multiple other implementations not listed. Any replacement and improvement made without violating the concept of the present invention shall fall within the protection scope of the present invention.
