Description

Technical Field

[0001] The utility model relates to the technical field of yarn mouths, and more particularly to an anti-reverse yarn mouth. Background Art

[0002] The yarn feeding device of the existing double-sided weft knitting machine has defects, which is manifested in that the yarn threading hole and the spandex groove are both opened on the front of the yarn feeding mouth, and the position layout of the spandex groove and the spandex guide wheel is actually unreasonable, which causes the spandex yarn to be excessively bent and easily reversed. Therefore, it is necessary to improve the structure. Utility Model Content

[0003] The purpose of the utility model is to provide an anti-reverse yarn mouth in order to solve the above technical problems.

[0004] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0005] An anti-reverse yarn mouth comprises a yarn mouth seat, a connecting rod, a yarn feeding mouth, a spandex seat and a spandex guide wheel; a yarn threading hole is provided on the front of the yarn feeding mouth, the spandex seat is mounted on the connecting rod, a plug hole is provided on the side wall of the spandex seat, a connecting shaft is inserted into the plug hole, and one end of the connecting shaft is rotatably connected to the spandex guide wheel;

[0006] A through slot is located on one side of the yarn feeder, along with a spandex slot. The upper portion of the slot extends through the top of the yarn feeder, while the lower portion of the slot is connected to the through slot. The slot is located directly below the spandex guide wheel. The through slot runs through the front and back of the yarn feeder. The vertical slot allows the spandex yarn to flow downward vertically. The bottom of the connecting rod is bolted to the yarn feeder, and the spandex holder and connecting rod are also bolted together. The spandex holder has a tightening bolt that secures the connecting shaft.

[0007] The inner diameter of the spandex groove gradually decreases from the top to the bottom. The spandex groove is configured to be wide at the top and narrow at the bottom, so as to facilitate the yarn to pass through and reduce the contact between the yarn and the spandex groove.

[0008] A thread loop is provided at the bottom of the spandex groove, the bottom of which extends into the through groove. The connection between the spandex groove and the through groove is prone to wear, and the outer wall of the spandex groove is thin, which can easily break over time, requiring the entire yarn feeder to be replaced. The thread loop is designed to increase the wear resistance of the connection between the spandex groove and the through groove. If the thread loop is excessively worn, it can be replaced separately, reducing costs. The bottom of the thread loop extends into the through groove, preventing the spandex yarn from touching the connection between the spandex groove and the through groove.

[0009] The wire passing ring has a structure that is wide at the top and narrow at the bottom.

[0010] The outer wall of the thread passing ring is covered with a rubber protective sleeve. The rubber protective sleeve is provided to increase the friction of the thread passing ring so that the thread passing ring is closely attached to the spandex groove, and the rubber material is easier to remove.

[0011] The top and bottom of the through groove are both concave.

[0012] The through-groove opening is provided with curved hooks at both the upper and lower portions. The curved hooks increase the thickness of the through-groove opening at its edges. Without these curved hooks, the edges of the through-groove opening would be sharp and could easily damage the yarn. This is avoided by providing these curved hooks.

[0013] The beneficial effects of the utility model are as follows:

[0014] By setting a spandex groove just below the spandex guide wheel, the spandex can pass through the spandex groove vertically downward, avoiding bending and reducing reverse yarn; the spandex groove is set to be wide at the top and narrow at the bottom to facilitate the passage of yarn and reduce the contact between the yarn and the spandex groove; by designing a wire ring, the wear resistance of the connection between the spandex groove and the through groove can be increased. When the wire ring is excessively worn, the wire ring can be replaced separately to reduce costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0022] Example 1

[0023] like Figures 1 to 4 As shown, this embodiment provides an anti-reverse yarn mouth, including a yarn mouth seat 1, a connecting rod 2, a yarn feeding mouth 3, a spandex seat 4 and a spandex guide wheel 5; the front of the yarn feeding mouth 3 is provided with a yarn threading hole 6, the spandex seat 4 is installed on the connecting rod 2, and the side wall of the spandex seat 4 is provided with a socket, and a connecting shaft 8 is inserted into the socket, and one end of the connecting shaft 8 is rotatably connected to the spandex guide wheel 5;

[0024] A through slot 9 is provided on one side of the yarn feeder 3. A spandex slot 10 is also provided on the yarn feeder 3. The upper portion of the spandex slot 10 extends through the top of the yarn feeder 3, and the lower portion of the spandex slot 10 is connected to the through slot 9. The spandex slot 10 is located directly below the spandex guide wheel 5. The through slot 9 extends through the front and back of the yarn feeder 3. The spandex slot 10 is vertically positioned, allowing the spandex yarn to be directed downward. The bottom of the connecting rod 2 is bolted to the yarn feeder 3, and the spandex holder 4 is also bolted to the connecting rod 2. The spandex holder 4 is provided with a tightening bolt 7, which is tightened to secure the connecting shaft 8. The connecting rod 2 is bolted to the yarn feeder holder 1. The connecting rod 2 is provided with a strip hole 14, and the yarn feeder holder 1 is provided with a screw hole. The strip hole 14 is used to adjust the installation position of the connecting rod 2. The bolt passes through the strip hole 14 and connects with the screw hole to secure the yarn feeder holder 1.

[0025] The inner diameter of the spandex groove 10 gradually decreases from the top to the bottom. The spandex groove 10 is configured to be wide at the top and narrow at the bottom to facilitate the passage of the yarn and reduce the contact between the yarn and the spandex groove 10.

[0026] A thread loop 11 is provided at the bottom of the spandex groove 10, and the bottom of the thread loop 11 extends into the through groove 9. The connection between the spandex groove 10 and the through groove 9 is easily worn, and the outer groove wall of the spandex groove 10 is thin, which is easy to break once it is worn, and the yarn feeder 3 needs to be replaced as a whole. The design of the thread loop 11 can increase the wear resistance of the connection between the spandex groove 10 and the through groove 9. When the thread loop 11 is excessively worn, the thread loop 11 can be replaced separately to reduce costs; the bottom of the thread loop 11 extends into the through groove 9, which can prevent the spandex yarn from touching the connection between the spandex groove 10 and the through groove 9.

[0027] The wire loop 11 is a structure that is wide at the top and narrow at the bottom.

[0028] The outer wall of the wire loop 11 is covered with a rubber protective sleeve 12. The friction of the wire loop 11 is increased by arranging the rubber protective sleeve 12 so that the wire loop 11 is in close contact with the spandex groove 10. In addition, the setting of the rubber material makes it easier to take out the entire wire loop 11.

[0029] The top and bottom of the through groove 9 are both concave.

[0030] The through slot 9 is provided with curved hooks 13 at both the upper and lower portions of the notch. The curved hooks 13 increase the thickness of the notch edge. Without these curved hooks 13, the notch edge of the through slot 9 would be sharp and could easily damage the yarn. This prevents this from happening.
