[0037] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0038] Example:

[0039] See also Figure 1-Figure 4A yarn core cooling mechanism includes a frame, a guide groove 1, a guide wheel 2, a pressing groove 3 and a lifting assembly. Specifically, the guide groove 1 is fixedly arranged on the frame, the guide groove 1 is a long strip structure, the cross-section of the guide groove 1 is a V-shaped structure, and the bottom surface of the inner side of the guide groove 1 is arc-shaped. There are a plurality of through holes 4 on the bottom surface of the guide groove 1, and the through holes 4 pass through the inner and outer sides of the guide groove 1.

[0040] There are two guide wheels 2 rotatably arranged on the frame, and the two guide wheels 2 are respectively close to the two ends of the guide groove 1. The wheel surface of the guide wheel 2 is a concave arc structure, and is arranged in the same direction as the inner side surface of the guide groove 1. Generally, the cross-section of the top of the guide wheel 2 is also a concave V-shaped structure, and has the same structure as the inner side surface of the guide groove 1.

[0041] The pressing groove 3 is located above the guide groove 1 . The pressing groove 3 is a U-shaped structure. The pressing groove 3 is buckled on the guide groove 1 . In addition, a fan 13 is provided on one side of the pressing groove 3 . The fan 13 sends external airflow into the interior of the guide groove 1 .

[0042] The lifting assembly is arranged on the frame, and the driving end of the lifting section is connected to the pressing groove 3, and drives the pressing groove 3 to reciprocate in the vertical direction above the guide groove 1.

[0043] In this embodiment, the guide wheel 2 is provided to guide the direction of the yarn core, and the lifting assembly is provided to lift the pressing groove 3 and place the yarn core in the guide groove 1. When working, the yarn core passes through the guide groove 1, and the fan 13 blows cool air into the guide groove 1, and the cool air then passes through the two ends of the pressing groove 3 and the through hole 4 on the guide groove 1. In this process, the cool air contacts the yarn core, takes away the heat on the yarn core, and thus cools the yarn core.

[0044] In the technical solution, the yarn core is cooled by adding a fan 13 and a pressing groove 3, and heat accumulation on the guide groove 1 is avoided, thereby ensuring that the yarn core can be cooled continuously and effectively.

[0045] In one specific embodiment:

[0046] The two ends of the guide groove 1 are mutually connected and bent downward. The through holes 4 in the guide groove 1 are all rounded, so that the through holes 4 are connected with smooth curved surfaces.

[0047] The main function of this embodiment is to prevent the edges and corners at the end of the guide groove 1 and the edges and corners at one end of the channel in the guide groove 1 from affecting the surface of the yarn core.

[0048] In another specific embodiment:

[0049] The cooling mechanism also includes two pressing wheels 11, which are respectively arranged corresponding to the two guide wheels 2 and respectively arranged above the two guide wheels 2. The wheel surface of the pressing wheel 11 is also a concave arc surface structure. At the same time, the width of the pressing wheel 11 is smaller than the width of the guide wheel 2, so that a part of the bottom of the pressing wheel 11 can be embedded in the top of the guide wheel 2, so that the bottom of the pressing wheel 11 and the top of the guide wheel 2 form a channel for the yarn core to pass through. By setting up the channel, the yarn core can be prevented from jumping under the action of the fan 13, so as to prevent the yarn core from jumping out of the concave wheel surface of the guide wheel 2.

[0050] In another specific embodiment:

[0051] The lifting assembly includes a connecting plate 5, a supporting plate 6, a cylinder 7, a guide rail 8, and a guide column 9. Specifically, the connecting plate 5 is connected to the pressing groove 3, and the connecting plate 5 and the fan 13 are respectively located on both sides of the pressing groove 3. The supporting plate 6 is located below the connecting plate 5, and the top surface of the supporting plate 6 is in a sliding contact state with the lower side surface of the connecting plate 5.

[0052] The bottom surface of the support plate 6 is fixedly connected to the end of the piston rod of the cylinder 7, and the length direction of the cylinder 7 is arranged along the vertical direction. The cylinder 7 is fixedly arranged on the frame.

[0053] The guide rail 8 is fixedly arranged on the frame, and the guide rail 8 is close to a side of the connecting plate 5 away from the pressing groove 3. The extension direction of the guide rail 8 is perpendicular to the length direction of the pressing groove 3, and a guide column 9 is also arranged on the connecting plate 5. The end of the guide column 9 away from the connecting plate 5 is slidably arranged on the guide rail 8.

[0054] In this embodiment, the cylinder 7 drives the support plate 6 to move, thereby driving the connecting plate 5 to move in the vertical direction, and then driving the pressing groove 3 to move in the vertical direction through the connecting plate 5, so the connecting plate 5 is the driving end of the lifting assembly. In addition, the movement trajectory of the connecting plate 5 and the pressing groove 3 can be limited by the guide column 9 and the guide rail 8.

[0055] In another specific embodiment:

[0056] The rotating shafts of the two pressing wheels 11 are rotatably arranged at both ends of the connecting plate 5. The pressing wheels 11 are connected to the guide wheel 2 through a gear train. The rotating shaft of the guide wheel 2 is connected to the output shaft of a motor 10. When the lifting assembly drives the connecting plate 5 to rise, the pressing wheels 11 rise together with it, thereby separating from the guide wheel 2, and making it easier to place the yarn core between the guide wheel 2 and the pressing wheels 11.

[0057] Since the guide wheel 2 and the pressure wheel 11 are connected by a gear set, after the lifting assembly drives the pressure wheel 11 to rise, the two gears in the gear set can be directly separated, and when the pressure wheel 11 is reset, the two gears can be meshed again.

[0058] In another specific embodiment:

[0059] A plurality of guide rails 8 are arranged in parallel on the frame, and each guide rail 8 is matched with a guide post 9. One section of the guide rail 8 is straight-line, and the other end is arc-shaped, and the arc-shaped section of the guide rail 8 is located at the top.

[0060] Preferably, the middle portion of the guide rail 8 is a through groove structure, the guide column 9 is cylindrical, and the guide column 9 is provided with two hemispherical limiting bodies 12 , and the two limiting bodies 12 are respectively located on the two sides of the guide rail 8 .

[0061] In this embodiment, by providing a plurality of guide rails 8 and guide posts 9, the stability of the movement of the connecting plate 5 and the pressing groove 3 can be enhanced. The upper half of the guide rail 8 is set to an arc shape, so that after the connecting plate 5 and the pressing groove 3 are driven to rise, the pressing groove 3 is in an inclined upward direction, which makes it easier to place the yarn core in the guide groove 1.

[0062] Preferably, the central angle of the arc-shaped section of the guide rail 8 is less than or equal to 90°, and the arc-shaped section of the guide rail 8 is connected to the straight end thereof in a tangent direction.

[0063] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
