[0002] Silk is a textile made of silk or synthetic fibers, man-made fibers, staple fibers, etc. It is a general term for fabrics woven purely or interwoven with silk or man-made silk. In ancient times, silk was a textile woven from silk (mainly mulberry silk, but also including a small amount of tussah silk and cassava silk). In modern times, due to the expansion of textile raw materials, all textiles whose warp threads are woven with artificial or natural filament fibers can be called silk in a broad sense.

[0029] The embodiment of the utility model provides a silk blank conveying and correcting mechanism.

[0030] See also Figure 1 , Figure 2 , Figure 3 and Figure 4A silk blank conveying correction mechanism includes a fixed frame 1, and the internal rotation of the fixed frame 1 is connected with a rolling rod 101, a rolling rod 102 and a rolling rod 103. There is a height difference between the rolling rods. The height difference is used to reduce the single distance in the silk conveying process to prevent sagging caused by long-distance conveying.

[0031] Please refer again Figure 1 , Figure 2 and Figure 3 Two tensioning mechanisms 2 are arranged outside the fixed frame 1. The tensioning mechanism 2 includes a stabilizing frame 201 and a bearing 203. The stabilizing frame 201 is installed on the outer surface of the fixed frame 1. During the transportation process, the silk may not be tightened due to the change in speed, which may easily cause more problems, so a tensioning mechanism 2 is required.

[0032] The rolling rod 101 is rotatably connected to the bearing 203, and the inner wall of the stabilizing frame 201 is slidably connected to the slider 202. The outer surface of the slider 202 is fixedly connected to two springs 204, and one end of each spring 204 away from the slider 202 is fixedly connected to the inner wall of the stabilizing frame 201. The bearing 203 is fixedly connected to the slider 202, and the spring 204 drives the slider 202. The rolling rod 101 and the bearing 203 are fixed inside the slider 202. Under the action of the spring, the slider 202 supports and tightens the moving rolling rod 101, so that the rolling rod 101 can always be tightened relative to the silk conveyor.

[0033] Please refer again Figure 1 and Figure 2 A grating scanner 4 is installed inside the fixed frame 1. The grating scanner 4 is an existing device. The principle model of the grating scanner 4 is not described in detail in this application. A correction mechanism 3 is arranged outside the fixed frame 1. The correction mechanism 3 includes a support block 309 and a deceleration block 302. The grating scanner 4 can generate a detection grating to detect the position of the silk in motion at all times. When the edge of the silk is detected to be offset, a signal can be sent to start the motor 304 to control the correction mechanism 3 to make corrections.

[0034] Please refer again Figure 1 , Figure 2 and Figure 4 One end of the second rolling rod 102 passes through the fixed frame 1 and is fixedly connected to the deceleration block 302 . The deceleration block 302 is made of rubber and can effectively decelerate the second rolling rod 102 in cooperation with the friction block 303 .

[0035] The support block 309 is internally slidably connected with a slide bar 317, the top of the slide bar 317 is fixedly connected with a pulley bracket 307, the pulley bracket 307 is internally rotatably connected with a pulley 306, the outer surface of the fixed frame 1 is fixedly connected with a mounting plate 301, the inner wall of the mounting plate 301 is fixedly connected with a motor 304, the output end of the motor 304 is fixedly connected with a cam 305, the cam 305 is transmission-connected with the pulley 306, the shape of the cam 305 is irregular, the motor 304 is started after receiving the grating signal, during the rotation of the cam 305, the top end farther than the shaft can push the pulley 306 and the slide bar 317 forward, at this time, the friction block 303 is pushed by the slide bar 317 to briefly contact the deceleration block 302, at this time, the speed of the rolling rod 102 can be temporarily decelerated, because the cam 305 is always rotating, during the starting process of the motor 304, the friction block 303 and the deceleration block 302 are contacted multiple times but the duration is very short, and multiple decelerations can make the correction effect better.

[0036] A second spring 308 is arranged outside the slide bar 317, and the two ends of the second spring 308 are fixedly connected to the pulley bracket 307 and the support block 309 respectively. The use of the second spring 308 can make the slide bar 317 recover quickly after being pushed, so that the operation of the device is more stable.

[0037] Two telescopic rods 310 are fixedly connected to the bottom surface of the support block 309, and a friction block 303 is arranged below the support block 309. One end of each telescopic rod 310 away from the support block 309 is fixedly connected to the top surface of the friction block 303. The telescopic rods 310 are used to limit the position of the friction block 303 and the support block 309 to prevent further damage caused by position displacement during the movement process.

[0038] Please refer again Figure 1 , Figure 2 , Figure 4 and Figure 5 The top surface of the friction block 303 is fixedly connected with a sleeve box 314, and the inner wall of the sleeve box 314 is slidably connected with a slide plate 313, the top of the friction block 303 is fixedly connected with a spring three 316, and the top of the spring three 316 is fixedly connected with a pressure plate 315, and the top of the pressure plate 315 is fixedly connected with a screw 311, the screw 311 penetrates the slide plate 313 and is slidably connected with the slide plate 313, and the top of the slide plate 313 is rotatably connected with a nut 312, and the nut 312 is threadedly connected with the screw 311, and the nut 312 can be screwed. When the nut 312 is screwed, the pressure plate 315 is tightened or loosened, thereby driving the height adjustment of the friction block 303. The purpose of adjusting the height of the friction block 303 is to be able to adjust the deceleration force. Different silks can withstand different forces, thereby preventing damage to the silk due to excessive force.

[0039] Working principle: When the device is used, the silk is first passed around the rolling rod 101, the rolling rod 2 102 and the rolling rod 3 103 in the order of top, bottom and top, and then the grating scanner 4 is adjusted to limit the grating range to the edge corresponding to the silk. Finally, the nut 312 inside the correction mechanism 3 is adjusted to adjust the friction block 303 to a suitable height to prevent tearing due to excessive deceleration force. During the silk transportation process, if the edge of the silk curls and causes overlap, the grating scanner 4 will identify it and send a signal. After receiving the signal from the grating scanner 4, the motor 304 starts to rotate the cam 305. The rotation of the cam 305 pushes the slide bar 317 downward, and the friction block 303 rubs against the deceleration block 302 to perform short and multiple decelerations on the rolling rod 2 102. At this time, the silk will be tightened due to the short deceleration. At this time, the curled edge will recover due to the tightening of the silk surface. Multiple decelerations can make the correction effect better.
