[0028] In actual use of an existing polyester high-strength yarn cutting device, the polyester yarn is not fixed during the cutting process and may move during the cutting process, resulting in inconsistent cutting lengths, affecting product quality and consistency. Therefore, a device that can fix the polyester yarn and adjust the tension of the polyester yarn is provided.

[0029] Embodiment 1:

[0030] like Figures 1 to 3 The utility model provides a thread cutting device for processing polyester yarn.

[0031] Specifically, by Figure 1-Figure 3A tangent device for processing polyester yarn is provided, comprising a polyester yarn 1, a transmission assembly 2 is arranged on the periphery of the polyester yarn 1, the transmission assembly 2 comprises two connecting rods 201 located below the polyester yarn 1, a winding roller 202 is fixedly installed on the outer wall of one of the connecting rods 201, a reeling roller 203 is fixedly installed on the outer wall of the other connecting rod 201, both ends of one of the connecting rods 201 are rotatably connected to a slider 204, a support rod 205 is arranged on one side of the reeling roller 203, and the support rod 205 is connected to the outer wall of one of the connecting rods 201. Pulleys 206 are fixedly installed, and first gears 207 are fixedly installed on the outer walls of the support rod 205 and one of the connecting rods 201. The two first gears 207 are meshed and connected, and a transmission belt 208 is transmission-connected between the two pulleys 206. A slow motor 209 is provided on one side of the winding roller 202, and the driving end of the slow motor 209 is connected to one end of one of the connecting rods 201. The polyester yarn 1 is located between the winding roller 202 and the unwinding roller 203 and is connected to the outer walls of the winding roller 202 and the unwinding roller 203.

[0032] The polyester yarn 1 is wound on the outer wall of the winding roller 202 and the unwinding roller 203. When the polyester yarn 1 needs to be cut, the connecting rod 201 with the winding roller 202 is driven by the slow motor 209 to rotate slowly clockwise. When the winding roller 202 rotates, the polyester yarn 1 on the outer wall of the unwinding roller 203 is pulled toward the position of the winding roller 202. When one of the connecting rods 201 rotates, it drives the support rod 205 and the pulley 206 to rotate through the transmission belt 208. When the support rod 205 rotates, it drives one of the first gears 207 Rotate, the first gear 207 connected to the support rod 205 drives another first gear 207 connected to the connecting rod 201 to rotate counterclockwise, thereby driving the connecting rod 201 and the unwinding roller 203 to rotate counterclockwise. After the unwinding roller 203 rotates counterclockwise, since the rotation directions of the winding roller 202 and the unwinding roller 203 are different, the polyester yarn 1 will be subjected to a tensile force between them, which helps to straighten the polyester yarn 1. The straightened polyester yarn 1 is more stable when being cut, and is not easy to deviate or shake, thereby improving the precision and accuracy of cutting;

[0033] And because the rotation speed of the slow motor 209 is very slow, the polyester thread 1 will not be broken due to the excessive rotation speed of the winding roller 202 and the unwinding roller 203. When the polyester thread 1 is straightened, the slow motor 209 can be quickly turned off. When the remaining polyester thread 1 needs to be cut, the slider 204 can be pulled to move to separate the two first gears 207. At this time, the polyester thread 1 on the outer wall of the unwinding roller 203 is rewound around the outer wall of the winding roller 202, and then the winding roller 202 is driven to rotate to pull the polyester thread 1 on the unwinding roller 203 to be wound around the outer wall of the winding roller 202 until it is wound to a position suitable for cutting. If the slider 204 is pushed back to its original position to make the two first gears 207 mesh again, in order to avoid the problem that the two first gears 207 cannot be stuck, one of the first gears 207 can be rotated during meshing so that it can be aligned.

[0034] Further:

[0035] like Figure 1 It is given that a base 3 is provided below the polyester yarn 1, and a plurality of fixed plates 4 are fixedly installed on the top of the base 3, two connecting rods 201 are located between the plurality of fixed plates 4, two sliders 204 are located inside two of the fixed plates 4 and are slidably connected to the inner walls of the fixed plates 4, one end of the support rod 205 is rotatably connected to the outer wall of the fixed plate 4, one end of one of the connecting rods 201 is rotatably connected to the outer wall of one of the fixed plates 4 and the outer wall of the connecting rod 201 is plugged into one of the fixed plates 4.

[0036] The base 3 is used to fix the fixed plate 4, so that the transmission component 2 and the polyester yarn 1 can be fixed and supported by the fixed plate 4. The slider 204 is slidably connected to the fixed plate 4, so that the user can pull the slider 204 to move along the fixed plate 4. At the same time, the fixed plate 4 also supports the slider 204. The connecting rod 201 is rotatably connected to the fixed plate 4, so that the fixed plate 4 can support the connecting rod 201 while keeping the connecting rod 201 rotating.

[0037] Further:

[0038] like Figure 1 It is given that a connecting plate 5 is fixedly installed between two fixed plates 4, an electric telescopic rod 6 is fixedly installed on the top of the connecting plate 5, the telescopic end of the electric telescopic rod 6 is connected to a mounting plate 7, and the bottom of the mounting plate 7 is connected to a cutting device 8, and the cutting device 8 corresponds to the polyester yarn 1.

[0039] The connecting plate 5 supports and fixes the electric telescopic rod 6, and the electric telescopic rod 6 can drive the mounting plate 7 and the cutting device 8 to move up and down. When the polyester yarn 1 needs to be cut, the mounting plate 7 and the cutting device 8 only need to be driven downward by the electric telescopic rod 6, so that the cutting device 8 contacts the polyester yarn 1 and the high-speed rotating cutting device 8 cuts the polyester yarn 1. After the cutting is completed, the mounting plate 7 and the cutting device 8 are lifted up.

[0040] Further:

[0041] like Figure 3 It is shown that the slow motor 209 is fixedly installed on the top of the connecting plate 5, and the top of the connecting plate 5 is fixedly connected with a fixing belt 14. The slow motor 209 is located inside the fixing belt 14, and the inner wall of the fixing belt 14 is tightly attached to the outer wall of the slow motor 209.

[0042] The connecting plate 5 supports the slow motor 209 to prevent the slow motor 209 from vibrating and moving during operation. The fixing belt 14 fixes the slow motor 209 tightly to the top of the connecting plate 5, which can effectively prevent the slow motor 209 and the connecting plate 5 from loosening.

[0043] Further:

[0044] like Figure 1-Figure 2 It is shown that a fixing ring 12 is fixedly installed on the outer wall of the slider 204 , a pull rod 13 is connected between the two fixing rings 12 , the outer wall of the fixing ring 12 abuts against the inner wall of the pull rod 13 , and the pull rod 13 is located on one side of the unwinding roller 203 .

[0045] The fixing ring 12 is fixed to the slider 204 , and then the pull rod 13 connects the two fixing rings 12 together. When the slider 204 needs to be pulled, only the pull rod 13 needs to be pulled to drive the two sliders 204 to move simultaneously, thereby achieving convenience.

[0046] Embodiment 2:

[0047] Further:

[0048] like Figure 2 It is shown that the slider 204 is inserted with the sleeve 9, the inner wall of the sleeve 9 is slidably connected with the sleeve rod 10, the end of the sleeve rod 10 away from the sleeve 9 is fixedly connected with the second gear 11, the second gear 11 is located between the two first gears 207 and meshingly connected with the two first gears 207, and the slider 204 is provided with a groove for the second gear 11 to slide into.

[0049] When the two first gears 207 are separated, pull out the sleeve rod 10 and the sleeve 9, and then rotate the second gear 11 or the first gear 207 to adjust the position where the second gear 11 and the two first gears 207 are engaged. When the first gear 207 connected to the support rod 205 rotates, it drives the second gear 11 to rotate counterclockwise, and then the second gear 11 drives the first gear 207 connected to the connecting rod 201 to rotate clockwise, so that the unwinding roller 203 can rotate in the same direction as the winding roller 202, so that the polyester yarn 1 can be more easily transmitted to the winding roller 202, and the winding roller 202 can be prevented from rotating alone and tearing the polyester yarn 1. Because the sleeve 9 and the slider 204 are plug-in, the second gear 11 can be pressed into the slider 204 when the two first gears 207 need to engage.

[0050] Working principle:

[0051] The polyester yarn 1 is wound on the outer wall of the winding roller 202 and the unwinding roller 203. When the polyester yarn 1 needs to be cut, the connecting rod 201 with the winding roller 202 is driven by the slow motor 209 to rotate slowly clockwise. When the winding roller 202 rotates, the polyester yarn 1 on the outer wall of the unwinding roller 203 is pulled toward the position of the winding roller 202. When one of the connecting rods 201 rotates, it drives the support rod 205 and the pulley 206 to rotate through the transmission belt 208. When the support rod 205 rotates, it drives one of the first gears 207 Rotate, the first gear 207 connected to the support rod 205 drives another first gear 207 connected to the connecting rod 201 to rotate counterclockwise, thereby driving the connecting rod 201 and the unwinding roller 203 to rotate counterclockwise. After the unwinding roller 203 rotates counterclockwise, since the rotation directions of the winding roller 202 and the unwinding roller 203 are different, the polyester yarn 1 will be subjected to a tensile force between them, which helps to straighten the polyester yarn 1. The straightened polyester yarn 1 is more stable when being cut, and is not easy to deviate or shake, thereby improving the precision and accuracy of cutting;

[0052] And because the rotation speed of the slow motor 209 is very slow, the polyester thread 1 will not be broken due to the excessive rotation speed of the winding roller 202 and the unwinding roller 203. When the polyester thread 1 is straightened, the slow motor 209 can be quickly turned off. When the remaining polyester thread 1 needs to be cut, the slider 204 can be pulled to move to separate the two first gears 207. At this time, the polyester thread 1 on the outer wall of the unwinding roller 203 is rewound around the outer wall of the winding roller 202, and then the winding roller 202 is driven to rotate to pull the polyester thread 1 on the unwinding roller 203 to be wound around the outer wall of the winding roller 202 until it is wound to a position suitable for cutting. If the slider 204 is pushed back to its original position to make the two first gears 207 mesh again, in order to avoid the problem that the two first gears 207 cannot be stuck, one of the first gears 207 can be rotated during meshing so that it can be aligned.

[0053] When the two first gears 207 are separated, pull out the sleeve rod 10 and the sleeve 9, and then rotate the second gear 11 or the first gear 207 to adjust the position where the second gear 11 and the two first gears 207 are engaged. When the first gear 207 connected to the support rod 205 rotates, it drives the second gear 11 to rotate counterclockwise, and then the second gear 11 drives the first gear 207 connected to the connecting rod 201 to rotate clockwise, so that the unwinding roller 203 can rotate in the same direction as the winding roller 202, so that the polyester yarn 1 can be more easily transmitted to the winding roller 202, and the winding roller 202 can be prevented from rotating alone and tearing the polyester yarn 1. Because the sleeve 9 and the slider 204 are plug-in, the second gear 11 can be pressed into the slider 204 when the two first gears 207 need to engage.

[0054] The above is only a preferred embodiment of the present invention, and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the present invention.
