AI Technical Summary
Existing twisting machines require additional tools or equipment to achieve the rotation of the bobbin during the yarn pulling process, which increases costs and makes bobbin disassembly inconvenient.
The system employs a combination structure of a fixed frame, a first guide, and a second guide, along with a lifting drive, to allow the yarn to extend upwards before entering the winding roller. The bobbin can be placed directly below the fixed frame. The design of the guide wheel and the limiting structure of the protruding part ensure stable yarn output.
The yarn can be pulled out smoothly without the need for the bobbin to rotate, which reduces costs, simplifies the bobbin replacement process, and improves the stability of use and the quality of the yarn.

Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the field of twisting machine, in particular, to a yarn guiding device for a twisting machine. BACKGROUND
[0002] When a plurality of yarns need to be twisted together into one yarn, a twisting machine can be used to achieve this. The principle is to pull the yarn out of the bobbin on which the yarn is wound, and extend the pulling line to the twisting machine. In order to better pull the yarn out, a corresponding mounting device is often needed to mount the bobbin so that the bobbin can rotate to achieve the pulling of the yarn out of the bobbin. However, the rotation of the bobbin requires additional tools or equipment, which will increase the cost and make the disassembly of the bobbin troublesome. CONTENT OF THE UTILITY MODEL

[0004] In order to solve the technical problems mentioned in the background part, some embodiments of the present application provide a yarn guiding device for a twisting machine, comprising: a fixed frame, a first guide and a second guide; the fixed frame is used to install the first guide and the second guide; the twisting machine forms a winding roller for winding yarn, the first guide is located above the winding roller, and the second guide is located below the winding roller; the yarn extends to the winding roller after winding around the first guide and the second guide.
[0005] Further, the guiding device further comprises a lifting driving member, which is used to drive the first guide to rise and fall.
[0006] Further, the fixed frame is used to form a placing plane below the first guide, the placing plane is used to place a bobbin, and the bobbin is vertically placed on the placing plane.
[0007] Further, a plurality of protruding parts are formed on the placing plane, and the bobbin is embedded in the protruding parts.
[0008] Further, the first guide comprises a first guide wheel, and the first guide wheel is rotationally connected with the fixed frame; the second guide comprises a second guide wheel, and the second guide wheel is rotationally connected with the fixed frame.
[0009] Further, the wrap angle of the yarn around the first guide wheel is greater than 120°, and the wrap angle of the yarn around the second guide wheel is greater than 120°.
[0010] Further, a stepped gap is formed on the protruding part, and the stepped gap is used to form a plurality of engaging surfaces with different sizes on the protruding part.
[0011] The application has the beneficial effect that the yarn in the bobbin is first extended upward and then enters the twisting machine, so that the yarn can be pulled out of the bobbin without rotating the bobbin, thereby only needing to place the bobbin on the ground to realize the outward pulling of the yarn, saving cost and making the replacement of the bobbin more simple.

[0025] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
[0026] Referring to Figures 1-4 ,
[0027] A yarn guide device for a twisting machine, comprising: a fixed frame 1, a first guide 2 and a second guide 3. The fixed frame 1 is used to install the first guide 2 and the second guide 3, and the twisting machine forms a winding roller 7 for winding yarn. The first guide 2 is located above the winding roller 7, and the second guide 3 is located below the winding roller 7; the yarn extends to the winding roller 7 after passing through the first guide 2 and the second guide 3. By using the method of first extending the yarn upward, then passing through the first guide 2 and entering the winding roller 7 through the second guide 3, the spool 5 can be directly placed below the first guide 2, and then the yarn on the spool 5 is pulled out upward, which can ensure the pulling out of the yarn without the need to fix the spool 5, and better reduce the cost of the spool 5 to pull out the yarn outward.
[0028] Specifically, the guiding device further comprises a lifting driving member 4, which is used to drive the first guiding member 2 to ascend and descend. The lifting driving member 4 comprises a guiding wheel 41, a rope 42, a winch 43 and a lifting frame 44. The lifting frame 44 is slidably connected with the fixed frame 1 and is used to mount the first guiding member 2. The winch 43 is arranged on the ground. One end of the rope 42 is connected with the winch 43 and the other end is connected with the lifting frame 44 through the guiding wheel 41. The winch 43 can wind and unwind the rope to make the lifting frame 44 ascend and descend, thereby realizing the ascending and descending of the first guiding member 2.
[0029] Specifically, the fixed frame 1 is used to form a placing plane below the first guiding member 2, the placing plane is used to place a bobbin 5, and the bobbin 5 is vertically placed on the placing plane. A plurality of protruding portions 6 are formed on the placing plane, and the bobbin 5 is embedded in the protruding portions 6. The bobbin 5 is embedded in the protruding portions 6, which aims to prevent the bobbin 5 from falling over, thereby better enabling the bobbin 5 to stand on the ground and avoiding the yarn from being wound and knotted, and ensuring the stability of use.
[0030] Specifically, the first guiding member 2 comprises a first guiding wheel 41, which is rotatably connected with the fixed frame 1; and the second guiding member 3 comprises a second guiding wheel 41, which is rotatably connected with the fixed frame 1. Preferably, the first guiding member 2 and the second guiding member are both fixed pulleys.
[0031] More specifically, the wrap angle of the yarn around the first guiding wheel 41 is greater than 120°, and the wrap angle of the yarn around the second guiding wheel 41 is greater than 120°. Then the area of contact between the yarn and the first guiding wheel 41 or the second guiding wheel 41 can be larger, and the friction between the yarn and the first guiding wheel 41 and the second guiding wheel 41 can be larger. When the yarn is driven, the sliding of the yarn on the guiding wheel 41 due to the damage of the bearing of the guiding wheel 41 after long-term use can be avoided. Thus, the guiding wheel 41 can be kept in a rotating state by using a larger friction force even when the bearing of the guiding wheel 41 is damaged, and the yarn can be prevented from being abraded, thereby better ensuring the quality of the yarn.
[0032] Specifically, a stepped gap is formed on the protruding portion 6, and the stepped gap is used to form a plurality of clamping surfaces with different sizes on the protruding portion 6. The stepped gap can form a plurality of clamping surfaces for contacting the inner wall of the bobbin 5, thereby being able to limit and fix the bobbin 5 with different sizes.
[0033] The above description is merely exemplary of some of the many possible embodiments of the present disclosure and of the principles thereof. It is to be understood that those skilled in the art will be able to devise various embodiments of the present disclosure without departing from the scope of the present disclosure as disclosed in the above description and attached claims, and that the scope of the present disclosure is not limited to the specific technical features described above. For example, the technical features described above can be replaced with other technical features with similar functions disclosed in the embodiments of the present disclosure (but not limited to) to form other technical solutions.
