DETAILED DESCRIPTION

[0028] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] Example 1

[0030] See also Figures 1 to 6 , which is the first embodiment of the utility model, provides a technical solution: a single-sided knitted fabric weaving auxiliary device, including a bottom plate 1, two L-shaped plates 2 are fixedly connected to the bottom plate 1, and a driving rod 3 is rotatably connected to the L-shaped plate 2. A winding machine is arranged outside the device, and the winding machine includes a servo motor and a winding roller, etc. The servo motor is started to drive the winding roller to rotate to realize the transmission of the yarn. The driving rod 3 is provided with an adjustment mechanism, which can be used to adjust the tension during the transmission of the yarn;

[0031] The adjusting mechanism includes a No. 1 driving motor 301 installed on the L-shaped plate 2, and the output end of the No. 1 driving motor 301 passes through the L-shaped plate 2 and is fixedly connected to one side of the driving rod 3. When the No. 1 driving motor 301 is started, the driving rod 3 is driven to rotate. Two connecting rods 302 are fixedly connected to the driving rod 3. The driving rod 3 rotates to drive the connecting rod 302 to rotate. The side of the connecting rod 302 away from the driving rod 3 is connected to a conveying roller 303. The connecting rod 302 rotates to drive the conveying roller 303 to rotate, thereby adjusting the angle between the yarn roller 11 and the yarn, and then adjusting the tension between the yarn and the yarn roller 11. A limiting mechanism is provided on the bottom plate 1, which can be used to limit the yarn when the yarn is conveyed.

[0032] Two mounting plates 8 are fixedly connected to the base plate 1, and pillars 9 are rotatably connected to the mounting plates 8. A No. 2 driving motor 10 is installed on one side of the mounting plate 8, and the output end of the No. 2 driving motor 10 passes through the mounting plate 8 and is fixedly connected to one side of the pillar 9. Starting the No. 2 driving motor 10 drives the pillar 9 to rotate.

[0033] A slide groove is provided in the support 9, in which a yarn roller 11 is slidably connected, and bolts are connected between the yarn roller 11 and the support 9. When the support 9 rotates, the yarn roller 11 is driven to rotate under the fixing action of the bolts to unfold the yarn.

[0034] A yarn feeding roller 12 is fixedly connected to the L-shaped plate 2 , and a plurality of yarn feeding wheels 1201 are fixedly connected to the yarn feeding roller 12 . One side of the yarn on the yarn roller 11 passes through the top of the conveying roller 303 and then passes through the yarn feeding wheel 1201 .

[0035] A hollow column 13 is fixedly connected to the bottom plate 1, and the hollow column 13 is located directly below the yarn feeding wheel 1201. A positioning rod 14 is slidably connected inside the hollow column 13. The positioning rod 14 can limit the yarn on the yarn feeding wheel 1201 to ensure that the yarn will not deviate when moving.

[0036] The width value of the positioning rod 14 is compatible with the inner diameter length value of the yarn feeding wheel 1201, so that the positioning rod 14 can better limit the yarn. A spring 15 is arranged between the bottom of the positioning rod 14 and the bottom of the hollow column 13. The setting of the spring 15 can ensure that the top of the positioning rod 14 is always in contact with the yarn on the yarn feeding wheel 1201.

[0037] Two guide rollers 16 are fixedly connected to the L-shaped plate 2 to provide guidance for the yarn when it moves. Universal wheels 17 are provided at the four corners of the bottom of the L-shaped plate 2 to facilitate the movement of the device.

[0038] When in use, the yarn on the yarn roller 11 is first passed over the conveying roller 303, and then passed through the guide roller 16 and the yarn feeding wheel 1201 in turn, and then fixed between the winding machine. By starting the No. 1 driving motor 301, the driving rod 3 is driven to rotate, thereby driving the connecting rod 302 to rotate, and then driving the conveying roller 303 to rotate. The conveying roller 303 rotates, driving the yarn of the conveying roller 303 to rise or fall, thereby adjusting the angle between the yarn roller 11 and the yarn, and then adjusting the tension between the yarn and the yarn roller 11, thereby improving the winding effect of the device.

[0039] Example 2

[0040] See also Figures 1 to 4 as well as Figure 6 , which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that: the limiting mechanism includes two screw rods 4 rotatably connected to the base plate 1, and the tops of the screw rods 4 are all set through the L-shaped plate 2, and a handle is installed on one side of the top of the screw rod 4 passing through the L-shaped plate 2. The handle installed on the screw rod 4 is manually rotated to drive the screw rod 4 to rotate.

[0041] A slider 5 is screwed on the screw rod 4. The rotation of the screw rod 4 drives the slider 5 to move linearly on the screw rod 4. The slider 5 is fixedly connected to a limit plate 6 on the side away from the screw rod 4, and the limit plate 6 is convex. The movement of the slider 5 drives the limit plate 6 to move, so that the height of the two limit plates 6 can be adjusted according to the angle of the conveying roller 303, so that the limit plate 6 can better position the yarn.

[0042] Two fixing rods 7 are fixedly connected on both sides of the bottom plate 1, and the side of the fixing rod 7 away from the bottom plate 1 is fixedly connected to the top of the L-shaped plate 2, and the fixing rod 7 is slidably connected to the limit plate 6. The setting of the fixing rod 7 makes the movement of the limit plate 6 more stable.

[0043] When in use, the handle installed on the screw rod 4 is manually turned to drive the screw rod 4 to rotate, thereby driving the slider 5 to move linearly on the screw rod 4, and then adjusting the height of the two limit plates 6 according to the angle of the conveying roller 303, so that the limit plates 6 can better position the yarn and avoid the yarn from being offset during the conveying process.

[0044] The remaining structures are the same as those of Example 1.
