DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Reference Figure 1-Figure 4, a yarn guide device for a textile machine that is easy to clamp, includes a machine body 1, a yarn winding roller 2, a limiting circular groove 3 and a vertical bracket 4 are provided in the machine body 1, the yarn winding roller 2 is arranged at the upper end of the machine body 1, and the limiting circular groove 3 is opened at one end of the yarn winding roller 2. When the yarn is wound on the yarn winding roller 2, the yarn end can be wound around the limiting circular groove 3 and tied and fixed, so that the yarn is connected to the yarn winding roller 2, so that the yarn winding roller 2 can be rotated to wind the yarn. Two vertical brackets 4 are fixedly connected to the left and right ends of the machine body 1 respectively;

[0028] The body 1 is further provided with a rotating mounting chamber 5, a limiting movable block 6, and a contact protrusion 13. The two rotating mounting chambers 5 are respectively rotatably mounted on the two vertical brackets 4. The two sets of limiting movable blocks 6 are respectively arranged at the two rotating mounting chambers 5 in a linearly movable manner. The two sets of contact protrusions 13 are respectively fixedly connected to the two sets of limiting movable blocks 6. The two sets of contact protrusions 13 can be made of silicone material.

[0029] The driving mechanism is arranged at the vertical bracket 4 and the rotating mounting chamber 5, and is used to drive two sets of contact protrusions 13 to perform four-point clamping on the two ends of the winding roller 2 to improve the stability of the winding roller 2 after clamping, and drive the winding roller 2 to rotate to wind the yarn on the winding roller 2.

[0030] There are four limit moving blocks 6 in a group, and the four limit moving blocks 6 in a group are equidistantly distributed around the circumference. The two groups of contact protrusions 13 are both semi-cylindrical structures. When the arc surface ends of the two groups of contact protrusions 13 are movably against the arc surface ends of the winding roller 2, the two ends of the winding roller 2 are clamped. A pushing cylinder 7 is fixedly installed on the machine body 1, and the output end of the pushing cylinder 7 is fixedly connected to a placement semi-arc plate 8. When the winding roller 2 is not clamped, the middle end of the winding roller 2 is first movably placed on the placement semi-arc plate 8, and then the winding roller 2 is lifted by pushing the cylinder 7, and the two ends of the winding roller 2 are respectively aligned with the center of the rotating installation chamber 5, so that there is no need for manpower to lift the winding roller 2, simplifying the clamping process. After the winding roller 2 is clamped, the placement semi-arc plate 8 is moved downward and away from the winding roller 2 to avoid affecting the winding of the yarn.

[0031] The driving mechanism includes an installation chamber, a guide groove 11 and a limit motor 14. The two installation chambers are respectively opened in the two rotating installation chambers 5. Figure 2 As shown, four guide grooves 11 are equidistantly arranged on a rotating mounting chamber 5, and the four guide grooves 11 are connected to the mounting chamber. Four limit moving blocks 6 are respectively slidably arranged in the four guide grooves 11 to allow the limit moving blocks 6 to move linearly. A limit motor 14 is fixedly installed in a mounting chamber.

[0032] The driving mechanism also includes a rotating shaft 15, a rotating disc 16 and a connecting rod 12. A rotating shaft 15 is fixedly connected to the output end of a limit motor 14, and the rotating disc 16 is fixedly connected to the rotating shaft 15. One end of the four connecting rods 12 is pin-connected to a rotating disc 16, and the other ends of the four connecting rods 12 are respectively pin-connected to the four limit moving blocks 6. Figure 2 and attached Figure 3 As shown, when the rotating disc 16 rotates clockwise, the connection point between the middle and upper end of the connecting rod 12 and the rotating disc 16 moves from the middle and upper end to the right middle end, and the connection point between the middle and upper end of the connecting rod 12 and the limiting moving block 6 moves from the highest point to the lowest point of the guide groove 11, thereby causing the connecting rod 12 to deflect in the horizontal direction.

[0033] The driving mechanism also includes a driving motor 9 and a rotating shaft 10. The two driving motors 9 are respectively fixedly connected to the two vertical brackets 4. The two rotating shafts 10 are respectively installed on the two vertical brackets 4 for rotation. One end of the two rotating shafts 10 is respectively fixedly connected to the output ends of the two driving motors 9, and the other ends of the two rotating shafts 10 are respectively fixedly connected to the two rotating installation chambers 5. After the yarn winding roller 2 completes clamping, the yarn winding roller 2 is driven to rotate by the driving motor 9 to wind the yarn around the yarn winding roller 2.

[0034] The functional principle of this utility model can be explained through the following operation modes:

[0035] First, place the yarn winding roller 2 on the placement semi-arc plate 8, then start the push cylinder 7, so that the push cylinder 7 drives the placement semi-arc plate 8 to move upward, so as to lift the yarn winding roller 2 and align the two ends of the yarn winding roller 2 with the center of the two rotating installation chambers 5 respectively;

[0036] Then start the limit motor 14, so that the limit motor 14 drives the rotating shaft 15 to rotate, and the rotating shaft 15 drives the rotating disk 16 to rotate, as shown in the attached figure. Figure 2 and attached Figure 3 As shown, when the rotating disc 16 rotates clockwise, the rotating disc 16 drives the four connecting long rods 12 to rotate, and the four connecting long rods 12 are deflected in the horizontal direction, so that the four limit moving blocks 6 move toward the center of the rotating installation chamber 5, so that the arc surface ends of the four contact protrusions 13 abut against the arc surface ends of the yarn winding roller 2, thereby clamping the two ends of the yarn winding roller 2, and then starting the pushing cylinder 7 to move the placing semi-arc plate 8 downward to move away from the yarn winding roller 2;

[0037] When the yarn needs to be wound, the yarn head is first wound around the limiting circular groove 3 and knotted to fix it, and then the driving motor 9 is started to drive the rotating shaft 10 to rotate, and the rotating shaft 10 drives the rotating installation chamber 5 to rotate, and then drives the winding roller 2 to rotate to wind the yarn around the winding roller 2.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
