A single / dual hole switchable textured wire mesh

Abstract

This utility model relates to the field of chemical fiber equipment technology, and discloses a single / double-hole switchable texturing yarn networker, including a networker body with two parallel yarn grooves formed on the body. An air jet hole is formed in the middle of each yarn groove, and a detachable plug is connected to the air jet hole. In use, when yarn bundles passing through both yarn grooves require networking, the plug does not need to be installed on the air jet hole. When one yarn bundle does not require networking, the plug is installed on the air jet hole on the yarn groove through which that yarn bundle passes, preventing normal air jetting and thus preventing networking of that yarn bundle. The air jetting state of the networker can be changed by adding or removing plugs, eliminating the need to replace the networker, thus facilitating production, saving on networker investment, and reducing production costs.

Description

Technical Field

[0001] This utility model relates to the field of chemical fiber equipment technology, and in particular to a single- or double-hole switchable texturing yarn network device. Background Technology

[0002] In the field of chemical fiber production, the production process of textured twisted yarn often involves the combination of S-twist and Z-twist to form torque-free yarn, where one yarn is S-twist and the other is Z-twist. After the two are twisted, more varieties can be produced by using different raw materials and processes.

[0003] When producing standard twisted yarn, a networker with two grooves is typically used, with one groove for S-twist and one for Z-twist yarns. However, when producing a special style of twisted yarn where one yarn is unnetworked and the other is networked, the existing networker is insufficient, requiring a custom-made networker with one groove having a hole and the other not. Conversely, when producing ordinary twisted yarn, a networker with two holes must be reverted to the original design.

[0004] This current situation, which requires the customization of special network devices, forces companies to increase their investment in spare parts, thereby increasing production costs. At the same time, frequent replacement of network devices also has a certain impact on production efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a single- or double-hole switchable spring-loaded wire mesh device. By simply removing and installing the plug, the air jet state of the mesh device can be changed without replacing the mesh device, which is convenient for production, saves on the investment in the mesh device, reduces production costs, and at the same time ensures the meshing effect and improves production efficiency.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A single / double-hole switchable texturing yarn mesher includes a mesher body with two parallel yarn grooves formed on it. An air jet hole is formed in the middle of each yarn groove, and a removable plug is connected to the air jet hole. In use, when yarn bundles passing through both yarn grooves require meshing, the plug does not need to be installed on the air jet hole. When one yarn bundle does not require meshing, the plug is installed on the air jet hole on the yarn groove through which that yarn bundle passes, preventing normal air jetting and thus preventing meshing of that yarn bundle. The air jetting state of the mesher can be changed by adding or removing plugs, eliminating the need to replace the mesher, thus facilitating production, saving on mesher investment, and reducing production costs.

[0008] The present invention is further configured such that the plug is in the shape of a "T". The T-shape provides a limit during insertion into the air jet hole and also facilitates the removal of the plug.

[0009] The plug includes a vertically arranged plug post and a plug head. The plug head is formed with an arc-shaped outer wall that matches the wire groove. The plug post is configured to cooperate with the air jet hole. The plug is inserted into the air jet hole to block it.

[0010] The present invention is further configured such that: the lower part of the jet hole is formed with an enlarged hole, and the enlarged hole and the jet hole are connected by a tapered hole;

[0011] An annular groove is formed on the outer wall of the end of the plunger furthest from the plug head. A rubber ring is fitted onto the annular groove, positioned below the air jet and against the inner wall of the conical hole. When the plunger is inserted into the air jet, the rubber ring is compressed within the annular groove. As the rubber ring moves below the air jet, it deforms and rests against the inner wall of the conical hole. The rubber ring acts as a barrier, preventing the plunger from being ejected from the air jet due to high-pressure gas. It also restricts the position of the plug, preventing excessive movement of the plug in the air jet and thus hindering the passage of the filament. Finally, the rubber ring increases the seal, preventing air leakage from the plugged air jet. When the plug is removed, pulling the plug head outward causes the rubber ring to be compressed again by a greater pressure, forcing it back into the annular groove, allowing the plug to be removed.

[0012] The present invention is further configured such that the cross-sections of the jet hole, the enlarged hole, the conical hole, and the plug are elliptical.

[0013] The long axis of the jet nozzle is set perpendicular to the extension direction of the wire groove, which can increase the width of the gas ejected from the jet nozzle and make the wire bundle passing through the wire groove have a better networking effect.

[0014] The present invention is further configured such that: both ends of the plug are formed with process grooves, through which the plug can be removed by inserting a corresponding tool into the process groove, and then removing the plug from the air vent, thereby facilitating the removal of the plug.

[0015] The outstanding effect of this utility model is:

[0016] Compared with existing technologies, the jet state of the networker can be changed through simple plug removal and installation, without the need to replace the networker. This facilitates production, saves on networker investment, reduces production costs, ensures network application effect, and improves production efficiency. Attached Figure Description

[0024] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0025] The following is for reference Figures 1 to 3 The present invention will be described as follows:

[0026] As shown in Figure 1, a single- or double-hole switchable elastic wire mesh includes a mesh body (1). Two parallel wire grooves 11 are formed on the mesh body 1. An air jet hole 12 is formed in the middle of the wire groove 11. The air jet hole 12 is connected to a detachable plug 2.

[0027] The plug 2 is T-shaped, as shown in Figure 2, and includes a vertically arranged plug post 21 and a plug head 22. The plug head 22 is formed with an arc-shaped outer wall 23 that matches the wire groove 11. The plug post 21 is matched with the air jet hole 12.

[0028] The lower part of the jet hole 12 is formed with an enlarged hole 13, and the enlarged hole 13 and the jet hole 12 are connected by a conical hole 14, as shown in Figure 3; an annular groove 24 is formed on the outer wall of the end of the plug 21 away from the plug head 22, and a rubber ring 3 is fitted on the annular groove 24. The rubber ring 3 is located below the jet hole 12 and abuts against the inner wall of the conical hole 14.

[0029] The cross-sections of the jet hole 12, the enlarged hole 13, the tapered hole 14, and the plug 21 are elliptical, and the major axis of the jet hole 12 is perpendicular to the extension direction of the wire groove 11.

[0030] The two ends of the plug 22 are formed with process grooves 25.

[0031] In actual production, when both filament bundles 9 need to be netted, the plug 2 is not installed, and the two filament bundles pass through the two filament grooves 11 respectively. The air jet hole 12 sprays air normally to net the filament bundles. When one of the filament bundles does not need to be netted, the plug 2 is installed on the air jet hole 12 on the corresponding filament groove 11, the plug 21 is inserted into the air jet hole 12, and the rubber ring 3 is attached to the inner wall at the conical hole 14 to block the air jet hole 12. The filament bundle corresponding to this filament groove 11 does not need to be netted, while the air jet hole 12 corresponding to the other filament groove 11 sprays air normally to net the corresponding filament bundle.

[0032] When it is necessary to remove the plug 2, insert a tool into the process grooves 25 at both ends of the plug head 22, pry the plug head 22, and the rubber ring 3 will be compressed and squeezed into the annular groove 24, so that the plug 2 can be removed from the air vent 12.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
