However, the protection scope of the present invention is not limited to the following embodiments. In the description of the present invention, words indicating directions or positional relationships such as "front", "rear", "left", and "right" are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0020] This embodiment discloses a textile winding device with a tension detection function, such as Figure 1-Figure 18 As shown, it includes a double-station winder 1, and the double-station winder 1 includes a base 101, an electric control unit 102, a rotating frame 103 and a winding shaft 104 arranged on the rotating frame 103, and is specifically configured as follows: Figure 1-Figure 5 As shown, an electric control unit 102 is arranged above the base 101, and a rotating frame 103 is rotatably arranged on one side of the electric control unit 102 through a rotating shaft. The rotating frame 103 rotates around the rotating shaft and is controlled by a motor. Two winding shafts 104 are also rotatably arranged on the rotating frame 103, and the two winding shafts 104 are also driven to rotate by the motor. It should be noted that the rotation drive motors 326 of the two winding shafts 104 are respectively electrically controlled by an independent motor, and the two winding shafts 104 are horizontally symmetrically arranged. In addition, the two winding shafts 104 are arranged as shafts that can be tightened, specifically, they can be arranged as air expansion shafts, so that the yarn tube 2 can be sleeved on the winding shaft 104 for fixation. Since the double-station winder 1 is a prior art, it will not be described in detail in this embodiment, and the prior art can be referred to for details.

[0021] The yarn is wound by the double-station winding machine 1, so that when winding, the yarn tube 2 is sleeved on one of the winding shafts 104 of the rotating frame 103 and fixed, and then the winding shaft 104 is driven to rotate by the motor, so that the yarn can be wound on the yarn tube 2. In addition, a yarn guide mechanism 3 is also provided on one side of the double-station winding machine 1. The yarn guide mechanism 3 allows the yarn to move along the axial direction of the yarn tube 2 during winding, so that the yarn can be evenly wound on the yarn tube 2. When the winding is completed and the shaft needs to be changed, the rotating shaft can be rotated by the motor to rotate the rotating frame 103, such as Figure 1 and Fig.18As shown, the two winding shafts 104 can rotate 180°, thereby switching the positions of the two winding shafts 104, wherein the winding shaft 104 that has been wound can be rotated to the waiting position, and the other winding shaft 104 can be rotated and moved to the winding position, and the automatic cutting and automatic connection of the yarn can be realized by setting the winding-changing mechanism 4, so that after the two winding shafts 104 complete the position switching, the winding-changing mechanism 4 is started to fix the yarn and the new yarn tube 2, and cut the yarn, thereby realizing the winding work. It should be noted that the winding-changing mechanism 4 is outside the rotation route of the winding shaft 104 when on standby.

[0022] like Figure 1-Figure 5 As shown, the yarn guiding mechanism 3 is arranged on one side of the winding station on the double-station winding machine 1 through a supporting frame 5, and is specifically located at the wire inlet end of the winding machine. It is specifically configured to include a guide column 301 and a reciprocating drive assembly 302 for controlling the guide column 301 to reciprocate along the axial direction of the winding shaft 104.

[0024] A guide hole 311 is provided inside the guide column 301, and when winding the yarn, one end of the yarn can be passed through the guide hole 311 and extended to the outer wall of the yarn drum 2 at the winding station, and then one end of the yarn is fixed to the outer wall of the yarn drum 2. When winding the yarn, the reciprocating drive assembly 302 can be started to make the guide column 301 reciprocate to guide the yarn, so that the yarn can be evenly wound on the outer wall of the yarn drum 2 along the axial direction of the yarn drum 2; The reciprocating drive assembly 302, in this embodiment, is specifically configured to include a fixed seat 321, a screw rod 322, a slide rail 323, a slide seat 324, a connecting seat 325 and a driving motor 326, wherein the fixed seat 321 is fixedly arranged on the outer wall of the vertical plate 503, and a screw rod 322 is rotatably arranged above the fixed seat 321 through a bearing, and the screw rod 322 is driven to rotate by the driving motor 326, and the upper end surface of the fixed seat 321 is also fixedly arranged with a slide rail 323, and a slide seat 324 is slidably arranged above the slide rail 323, and the outer wall of the slide seat 324 A connecting seat 325 is fixedly arranged, a threaded hole is opened on the connecting seat 325, and the connecting seat 325 is threadedly connected to the screw rod 322 through the threaded hole, and the guide column 301 is fixedly arranged above the connecting seat 325, and then, the screw rod 322 is driven to rotate forward and reverse by the driving motor 326, and the connecting seat 325 is moved back and forth laterally through the thread transmission, and a proximity sensor 6 is installed on the fixed seat 321, and the connecting seat 325 is moved back and forth through the proximity sensor 6. It should be noted that the moving stroke of the connecting seat 325 is less than the length of the yarn tube 2.

[0025] During winding, improper tension control may lead to yarn breakage, reduced winding quality, and even equipment damage. Therefore, the tension needs to be monitored. In this embodiment, Figure 1-Figure 3 As shown, a tension detection mechanism 8 is provided at the yarn inlet end; Specifically, the tension detection mechanism 8 includes a mounting frame 801, a tensioning plate 802, a driving push rod 803, a tension wheel 804, a limit shaft 805, a pressure plate 806, a support spring 807 and a pressure sensor 808, wherein the mounting frame 801 is fixedly connected to the support frame 5, and a tensioning plate 802 is longitudinally slidably arranged on the mounting frame 801 through the slide rail 323, and the tensioning plate 802 can be lifted and slid, and a driving push rod 803 is arranged below the tensioning plate 802 to control its lifting and lowering, and a tension wheel 804 is also arranged on the tensioning plate 802, and the tension wheel 807 is provided with a tensioning plate 804. A limit shaft 805 is fixedly arranged at the bottom of the wheel frame of 04, and the limit shaft 805 passes through the tensioning plate 802, and the limit shaft 805 is slidably plugged with the tensioning plate 802, and a pressure plate 806 is fixedly arranged on the outer wall of the limit shaft 805, and a support spring 807 is arranged between the pressure plate 806 and the tensioning plate 802, which is used to rebound the tension wheel 804 upward, and a pressure sensor 808 is arranged on the tensioning plate 802 and at the bottom of the support spring 807, and the pressure sensor 808 monitors the contact pressure at the end of the support spring 807, and then feeds back the tension of the yarn in real time.

[0026] Through the above arrangement, when the yarn is wound, the yarn is guided from above the tension wheel 804, and then the electric push rod 4212 is activated to move the tensioning plate 802 upward. The tension of the yarn is adjusted by moving the tension wheel 804 upward. At the same time, the tension wheel 804 will be affected by the yarn and compress the support spring 807. The pressure sensor 808 monitors the pressure data. In the subsequent winding, when the tension changes, the tension wheel 804 will move up or down, and the support spring 807 will be compressed and released to varying degrees. The pressure sensor 808 monitors its contact pressure and then determines the tension based on the pressure data. The staff can choose to stop winding based on the pressure data, thereby improving the reliability of winding.

[0027] Roll changing mechanism 4, such as Figure 1-Figure 8 As shown, the roll changing mechanism 4 specifically includes a cutting component 401 and a fixing component 402, wherein after the two winding shafts 104 switch positions, the cutting component 401 is used to cut the yarn between the two winding shafts 104, and the fixing component 402 is used to fix one end of the cut yarn to the new yarn tube 2, thereby changing the roll; It should be noted that when changing the winding, the yarn is first fixed to the new yarn tube 2, and then the yarn is cut.

[0028] In order to facilitate the fixation of the yarn and the yarn tube 2, as Figure 1-Figure 10 As shown, in the present embodiment, the yarn tube 2 is specifically configured to include a tube body 201 and a connecting ring 202 arranged at one end of the tube body 201, and the connecting ring 202 and the tube body 201 are connected via a connecting assembly 203, and the connecting assembly 203 enables the outer wall of one end face of the tube body 201 to fit tightly with the end face of one end of the connecting ring 202, and thus when fixing the yarn, the yarn can be fixed between the connecting ring 202 and the tube body 201, and the connecting ring 202 and the tube body 201 can clamp and fix one end of the yarn via the connecting assembly 203.

[0029] like Figure 4-Figure 12As shown, the barrel 201 includes a hollow tube 211 and a fixing ring 212 fixedly arranged at one end of the tube 211, and the fixing ring 212 is integrally formed with the tube 211, and the fixing ring 212 is concentrically arranged with the tube 211, and the inner diameter of the fixing ring 212 is the same as the inner diameter of the tube 211. It should be noted that the outer diameter of the fixing ring 212 is smaller than the outer diameter of the tube 211, so that a sleeve space is provided in the fixing ring 212 part, and the connecting ring 202 can be slidably sleeved on the fixed ring 212. The outside of the fixed ring 212, in addition, the inner hole of the cylinder 201 matches the outer diameter of the winding shaft 104, and the cylinder 201 can be movably sleeved on the outer wall of the winding shaft 104, and then when the winding work is performed, the cylinder 201 can be sleeved on the outer wall of the winding shaft 104, and then the outer diameter of the winding shaft 104 is expanded, so that the outer wall of the winding shaft 104 is expanded and fits tightly with the inner wall of the cylinder 201, and then the cylinder 201 is fixed, and then the winding shaft 104 is rotated so that the yarn can be wound on the outer wall of the cylinder 201.

[0030] The connecting ring 202 is concentrically arranged with the cylinder 201, and the connecting ring 202 is slidably sleeved on the outside of the fixed ring 212, so that the connecting ring 202 can move at one end of the tube 211, and the end faces of the connecting ring 202 and the tube 211 facing each other are tightly fitted with each other through the connecting component 203. It should be noted that friction lines can be provided on the side of the connecting ring 202 facing the cylinder 201, so that the friction force makes the clamping and fixing of the yarn by the connecting ring 202 and the tube 211 more stable.

[0031] like Figure 8-Figure 12As shown, the connecting assembly 203 includes a plug hole 231, a plug column 232, a movable groove 233, a movable disk 234, a push rod 235, a through hole 236 and a reset spring 237, wherein the end surface of the tube 211 facing the connecting ring 202 is provided with a plug hole 231, and at least two plug holes 231 are provided. In this embodiment, the number of the plug holes 231 is set to four, and the four plug holes 231 are arranged in a circular array with the center of the tube 211 as the center. The inside of the four plug holes 231 The plug-in column 232 is slidably plugged in, and a movable groove 233 is opened inside the tube wall of the tube 211, and the number of the movable grooves 233 is the same as the plug-in hole 231. The movable grooves 233 and the plug-in hole 231 are concentrically arranged and connected to each other, and the movable disk 234 is movably plugged in the movable groove 233, and the outer diameter of the movable disk 234 is larger than the inner diameter of the plug-in hole 231, and one end of the plug-in column 232 extends into the movable groove 233 and is fixedly connected to the movable disk 234, so that the plug-in of the plug-in column 232 is limited by the movable disk 234. The other end of the plug-in column 232 is fixedly connected to one end of the connecting ring 202. In addition, a return spring 237 is also provided inside the movable groove 233, and the return spring 237 is sleeved on the outside of the plug-in column 232. One end of the return spring 237 contacts the end surface of the movable disk 234, and the other end contacts the inner wall of the movable groove 233 toward the plug-in hole 231, and then the return spring 237 is used to elastically control the connecting ring 202, and the return spring 237 makes the movable disk 234 rebound in the opposite direction of the connecting ring 202, so that The connecting ring 202 can fit tightly with the end face of the tube 211. In addition, a push rod 235 is fixedly arranged on the other end face of the movable disk 234. The push rod 235 is specifically arranged on the side of the movable disk 234 opposite to the connecting ring 202, and the other end of the push rod 235 passes through the through hole 236 along the axial direction of the tube 211 and extends to the other end of the tube 211 through the tube wall of the tube 211. The other end of the push rod 235 has a section extending to the outside of the other end of the tube 211, and the outer wall of the push rod 235 is slidably plugged into the through hole 236.

[0032] Therefore, through the setting of the connecting component 203, one end of the yarn can be clamped between the connecting ring 202 and the tube 211, and the connecting ring 202 and the tube 211 are tightly fitted and clamped by the reset spring 237, so that one end of the yarn is fixed. When it is necessary to loosen the fitting contact between the connecting ring 202 and the tube 211, it is necessary to push one end of the push rod 235 located at the other end of the tube 211 toward the connecting ring 202, so that the movable disk 234 drives the plug-in column 232 toward the connecting ring 202, and then the plug-in column 232 can drive the connecting ring 202 to slide on the outer wall of the fixed ring 212, so that there is a gap between the connecting ring 202 and the tube 211, and after the push rod 235 is loosened, the connecting ring 202 can continue to fit tightly with the tube 211 through the reset spring 237.

[0033] Based on the above arrangement, when fixing the yarn, the connecting ring 202 needs to be separated from the tube 211, and the yarn needs to be pressed down so that the yarn is stuck at the connection between the connecting ring 202 and the tube 211.

[0042] The principle of the present invention is as follows: when the present invention is working, first one end of the yarn is fixed to the cylinder 201 at the winding station, and then the double-station winding machine 1 works, so that the winding shaft 104 rotates to wind the yarn, and the yarn can be evenly wound on the outer wall of the cylinder 201 through the guidance of the yarn guide mechanism 3. When the roll needs to be changed, the yarn guide mechanism 3 stops working and the guide column 301 stops at a position corresponding to the connection between the connecting ring 202 and the tube 211. Then the double-station winding machine 1 is started, and the rotating frame 103 is rotated by the motor. , so that the two winding shafts 104 can rotate 180 degrees, and then the two winding shafts 104 can switch positions, wherein the winding shaft 104 that has been wound can be rotated to the waiting position, and the other winding shaft 104 can be rotated and displaced to the winding position. At this time, the yarn on the finished winding shaft 104 is not cut, and then the electric push rod 4212 is started, so that the lower pressure plate 4213 is lowered, first the lower pressure plate 4213 is lowered to drive the lifting plate 4222 to lower, and the yarn is pressed down by the lifting plate 4222, and the yarn is stuck at the connection between the connecting ring 202 and the tube 211 The first top block 4236 contacts the second top block 4237, so that the second top block 4237 drives the top plate 4232 to move toward the winding shaft 104, so that the top ring 4231 moves and contacts the top rod 235, and pushes the top rod 235 so that the connecting ring 202 is pushed and separated from the tube 211, and the yarn enters the connecting ring 202 and the tube 211 as the lifting plate 4222 continues to press down. The top block 4237 is separated, and the second top block 4237 is reset by the connecting spring 4234, so that the top ring 4231 is reset. Without the push of the top ring 4231, the connecting ring 202 is reset by the reset spring 237 and fits tightly with the tube 211 again to clamp the yarn. Then, the scissors cut the yarn under the tension of the traction rope 412, and the subsequent electric push rod 4212 drives the lower pressure plate 4213 to rise and reset, while the double-station winder 1 continues the winding work, automatically completing the roll changing, yarn cutting and fixing of the yarn to the new tube 201.
