[0029] Depend on Figure 1As shown, two groups of sliding brackets 2 are symmetrically mounted on the cooling pool 1 and have the freedom of movement in the horizontal direction. A first rotating rod 3 is rotatably mounted between the two sliding brackets 2 in the same group. Therefore, when in use, the two first rotating rods 3 are used for feeding and receiving materials respectively, and the specifications of the two first rotating rods 3 are the same;

[0030] Depend on Figure 1 As shown, the lifting plate 4 is located directly above the cooling pool 1 and has the freedom of movement in the vertical direction. Two groups of mounting ears 5 with holes are symmetrically fixed on the bottom surface of the lifting plate 4. A second rotating rod 6 is rotatably installed between the two mounting ears 5 with holes in the same group, so that the lifting plate 4 drives the second rotating rod 6 to descend, and the polyester monofilament is pressed into the cooling pool 1 through the second rotating rod 6.

[0031] Depend on Figure 1 and Figure 2 As shown, the top end of the connecting column 72 is fixedly connected to the lifting plate 4, and the bottom end is fixedly connected to the linkage plate 71. One end of the flip connecting arm 73 is hinged to the linkage plate 71, and the other end is hinged to the sliding bracket 2. When the lifting plate 4 descends, the lifting plate 4 uses the connecting column 72 to push the linkage plate 71 down, so that the flip connecting arm 73 flips and moves. The flip connecting arm 73 pulls the sliding brackets 2 on both sides toward the inside for a certain distance, so that the two first rotating rods 3 are brought toward the inside for a certain distance, thereby avoiding the stretching of the polyester monofilament, ensuring the production quality of the polyester monofilament, and greatly improving the safety.

[0032] Depend on Figure 1 and Figure 2 As shown, two spaced connection columns 72 are fixed between the lifting plate 4 and the linkage plate 71 to improve the stability of the connection between the linkage plate 71 and the lifting plate 4.

[0033] Depend on Figure 1 and Figure 3 As shown, it also includes a fixed frame 13 and a guide rod 14. The two fixed frames 13 are symmetrically fixed on the cooling pool 1. The guide rod 14 is fixed between the two fixed frames 13 and passes through the sliding bracket 2. The guide rod 14 is used to guide the sliding bracket 2. The two fixed frames 13 are used to limit the moving range of the sliding bracket 2 to ensure the stability of the sliding bracket 2.

[0034] Depend on Figure 1 and Figure 3 As shown, two guide rods 14 are fixed between the two fixing frames 13 and are spaced apart from each other to ensure the stability of the sliding bracket 2 and prevent the sliding bracket 2 from rotating.

[0035] Depend on Figure 1 and Figure 4As shown, it also includes a power mechanism 8, and the power mechanism 8 includes a lower fixed plate 81, an upper fixed plate 82, a support column 83, a threaded column 84 and an asynchronous motor 85. The lower fixed plate 81 is fixed on the cooling pool 1, and the two support columns 83 are symmetrically fixed on the lower fixed plate 81 and penetrate the lifting plate 4. The upper fixed plate 82 is fixed to the top of the support column 83. The threaded column 84 is rotatably installed between the lower fixed plate 81 and the upper fixed plate 82, and the threaded column 84 penetrates the lifting plate 4 and is connected to the lifting plate 4 by threaded screwing. The asynchronous motor 85 is fixed on the upper fixed plate 82 to drive the threaded column 84 to rotate. The asynchronous motor 85 is started to drive the threaded column 84 to rotate. Under the action of the threaded screwing, the lifting plate 4 rises or falls along the support column 83.

[0036] Depend on Figure 1 and Figure 3 As shown, it also includes a servo motor 15, which is fixed on the sliding bracket 2 and is used to drive the first rotating rod 3 to rotate, so as to realize the feeding and receiving of polyester monofilaments and ensure the stability of the first rotating rod 3. When the servo motor 15 is not working, the first rotating rod 3 remains stationary.

[0037] Depend on Figure 1 As shown, a water inlet 9 is fixed at the top of the outer side surface of the cooling pool 1, a drain port 11 is fixed at the bottom, and an interface flange 10 is fixed on the water inlet 9. A sealing screw cap 12 is installed on the drain port 11 by threaded engagement. It is convenient to inject cooling water into the cooling pool 1 through the water inlet 9. The sealing screw cap 12 can be unscrewed later to discharge the cooling water, which is convenient for replacing the cooling water.

[0038] Working principle and use process of the utility model: When the cooling device for polyester monofilament production of the utility model is used, a proper amount of cooling water is injected into the cooling pool 1 through the water injection port 9, and the two first rotating rods 3 are respectively driven by independent servo motors 15, which are respectively used to realize the feeding and receiving of polyester monofilament, so that the feeding and receiving are carried out synchronously;

[0039] The asynchronous motor 85 is started to drive the threaded column 84 to rotate. Under the action of the thread rotation, the lifting plate 4 is lowered along the support column 83, and the lifting plate 4 drives the second rotating rod 6 to descend. The polyester monofilament is pressed into the cooling pool 1 through the second rotating rod 6, and the polyester monofilament is continuously cooled by the cooling water in the cooling pool 1 until all the polyester monofilaments on the first rotating rod 3 are cooled.

[0040] When the lifting plate 4 descends, the lifting plate 4 uses the connecting column 72 to push the linkage plate 71 downward, so that the flip connecting arm 73 flips and moves, and the flip connecting arm 73 pulls the sliding brackets 2 on both sides to move closer to the inside by a certain distance, so that the two first rotating rods 3 move closer to the inside by a certain distance, thereby avoiding the stretching of the polyester monofilament, ensuring the production quality of the polyester monofilament, and greatly improving the safety;

[0041] It should also be noted that the utility model drives the second rotating rod 6 to descend vertically through the lifting plate 4 to press the polyester monofilament into the cooling pool 1. The polyester monofilament descends vertically and has high stability, thus avoiding the problem of lateral deviation of the polyester monofilament.

[0042] It should be noted that the asynchronous motor 85 and the servo motor 15 are both conventional commercially available devices with built-in power switches. Those skilled in the art can make conventional selections based on usage requirements. Their working principles are common knowledge known to those skilled in the art and have been fully disclosed in the prior art, so they will not be elaborated in this article.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
