Description

Technical Field

[0001] This utility model relates to the technical field of circular knitting machine components, specifically a yarn guiding device for a double-sided circular knitting machine. Background Technology

[0002] The yarn guide plays an important role in the circular knitting machine. It is mainly used to guide the yarn through the knitting needles and ensure that the yarn can smoothly enter the knitting area to complete the knitting process of the fabric.

[0003] Existing patent application number: 202022987284.1 A yarn guiding structure for a circular knitting machine includes a mounting frame disposed on the circular knitting machine and a yarn guiding device disposed on the mounting frame. The yarn guiding device includes a mounting base disposed on the mounting frame and a yarn guiding plate disposed on the mounting base. The yarn guiding plate is provided with a yarn guiding hole for the yarn to pass through. The yarn guiding plate is rotatably and slidably connected to the mounting base by a positioning member.

[0004] The aforementioned patent describes a yarn guide for a circular knitting machine. In use, the yarn passes through the slots on the yarn guide for guidance. Although existing yarn guides have a lubricating coating on the inner wall of the slots to reduce friction, in actual application, the yarn still experiences varying degrees of wear due to direct movement and friction within the slots, thus affecting fabric quality. Furthermore, the lifespan of the yarn guide itself is shortened due to wear. Therefore, we propose a yarn guide device for a double-sided circular knitting machine to solve the above problems. Utility Model Content

The wheel-type yarn guiding mechanism includes a threaded groove, an upper yarn guiding component, and a lower yarn guiding component. A threaded groove is longitudinally provided at the front end of the yarn guide. An upper yarn guiding component is installed at the upper end of the inner side of the threaded groove. The upper yarn guiding component includes an upper threaded sleeve, an upper nut, an upper through hole, and an upper guide wheel. The upper threaded sleeve is threaded into the upper end of the inner side of the threaded groove. An upper nut is fixedly fitted onto the upper end of the outer surface of the upper threaded sleeve. An upper through hole is provided through both the upper and lower ends of the upper threaded sleeve. An upper guide wheel is rotatably installed on the top side wall of the upper through hole. A lower yarn guide is installed on the lower end of the inner side of the threaded groove. The lower yarn guide includes a lower threaded sleeve, a lower nut, a lower through hole, and a lower guide wheel. The lower threaded sleeve is screwed into the lower end of the inner side of the threaded groove. A lower nut is fixedly fitted onto the lower end of the outer surface of the lower threaded sleeve. A lower through hole is provided through both the upper and lower ends of the lower threaded sleeve. A lower guide wheel is rotatably installed on the bottom side wall of the lower through hole.

[0007] Preferably, the upper yarn guide and the lower yarn guide have the same structural dimensions.

[0021] Please see Figure 1 This utility model provides a yarn guiding device for a double-sided circular knitting machine, including a yarn guide 1 and a wheel-type yarn guiding mechanism 2, with the wheel-type yarn guiding mechanism 2 provided at the front end of the yarn guide 1.

[0022] Please see Figure 2-5 This utility model provides a yarn guiding device for a double-sided circular knitting machine. The wheel-type yarn guiding mechanism 2 includes a threaded groove 21, an upper yarn guiding component 22, and a lower yarn guiding component 23. The front end of the yarn guide 1 has a longitudinally penetrating threaded groove 21. The upper yarn guiding component 22 is installed on the upper inner side of the threaded groove 21. The upper yarn guiding component 22 includes an upper threaded sleeve 221, an upper nut 222, an upper through hole 223, and an upper guide wheel 224. The upper threaded sleeve 221 is screwed into the upper inner side of the threaded groove 21. The upper nut 222 is fixedly fitted onto the upper upper surface of the upper threaded sleeve 221. The upper threaded sleeve 221 has an upper through hole 223 penetrating both the upper and lower ends. An upper guide wheel 224 is rotatably mounted on the top side wall of hole 223. The upper yarn guide 22 serves to guide the yarn. A lower yarn guide 23 is installed on the lower end of the inner side of the threaded groove 21. The lower yarn guide 23 includes a lower threaded sleeve 231, a lower nut 232, a lower through hole 233, and a lower guide wheel 234. The lower threaded sleeve 231 is screwed into the lower end of the inner side of the threaded groove 21. The lower nut 232 is fixedly fitted onto the lower end of the outer surface of the lower threaded sleeve 231. The lower through hole 233 is provided through both the upper and lower ends of the lower threaded sleeve 231. The lower guide wheel 234 is rotatably mounted on the bottom side wall of the lower through hole 233. The lower yarn guide 23 serves to guide the yarn.

[0023] To further explain, the upper yarn guide 22 and the lower yarn guide 23 have the same structural dimensions, which makes the upper yarn guide 22 and the lower yarn guide 23 interchangeable and interchangeable, with good versatility.

[0024] To further explain, the depth of the threaded groove 21 is twice the thread length on the surface of the upper threaded sleeve 221, so that the threaded groove 21 can provide sufficient screw-in length for the upper threaded sleeve 221 and the lower threaded sleeve 231, and avoid the upper threaded sleeve 221 and the lower threaded sleeve 231 squeezing each other.

[0025] To further explain, the axial directions of the upper through hole 223 and the lower through hole 233 are in the same straight line direction, ensuring that the yarn can pass smoothly through the upper through hole 223 and the lower through hole 233.

[0026] To further clarify, the inner diameter of the upper through hole 223 and the lower through hole 233 is not less than 10mm to ensure the passage of yarn.

[0027] To further explain, the upper threaded sleeve 221 and the lower threaded sleeve 231 have a rotation angle of not less than 360° within the threaded groove 21, which has good angle adjustment and can adjust the direction of the guide wheel to match the yarn direction.

[0028] The working principle is as follows:

[0029] First, install the yarn guide 1 to the designated position, and then screw the upper yarn guide 22 and the lower yarn guide 23 into the upper and lower ends of the threaded groove 21 respectively to complete the preparation work.

[0030] Second, before use, first adjust the position of the upper guide wheel 224 according to the direction of yarn introduction. Assuming the yarn is introduced from the right, use a wrench to turn the upper nut 222 to control the upper threaded sleeve 221 to rotate until the upper guide wheel 224 moves to the right of the upper through hole 223, so that the position of the upper guide wheel 224 is directly opposite to the direction of yarn introduction. The lower guide wheel 234 is adjusted according to the direction of yarn exit. Assuming the yarn is exited from the left, use a wrench to turn the lower nut 232 to control the lower threaded sleeve 231 to rotate until the lower guide wheel 234 moves to the left of the lower through hole 233, so that the position of the lower guide wheel 234 is directly opposite to the direction of yarn exit, thus completing the orientation adjustment.

[0031] Third, in use, the yarn is first inserted from top to bottom through the upper through hole 223 and the lower through hole 233, and the end of the yarn is connected to the knitting mechanism of the circular knitting machine. During the process of the yarn guide 1 guiding the yarn, the yarn will be placed on the surface of the upper guide wheel 224 and guided into the inner side of the upper through hole 223 to avoid the yarn rubbing at the top edge of the upper through hole 223. Subsequently, the yarn is placed on the surface of the lower guide wheel 234 and guided out into the inner side of the lower through hole 233 to avoid the yarn rubbing at the bottom edge of the lower through hole 233, effectively reducing yarn wear and improving fabric quality.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
