[0028] In this embodiment, refer to Figure 2 and Figure 4, the deviation rectifying mechanism 2 includes fixed boxes 201 fixedly connected to the front and back of the centers of both sides of the outer wall of the mounting base 1.

A traction rope 205 is fixedly connected to the outer wall of the sliding frame 202 at a position close to the mounting base 1. A winding shaft 206 is fixedly connected to the outer wall of the traction rope 205 inside the fixed box 201. Push springs 207 are fixedly connected to the outer wall of the mounting base 1 on the front and back of the traction rope 205. A worm gear 208 is fixedly connected to the outer wall of the winding shaft 206 on the back of the traction rope 205. A worm 209 is meshed and connected to the outer wall of the worm gear 208 at a position away from the mounting base 1.

[0030] In this embodiment, referring to Figure 1 and Figure 3 the adjusting mechanism 4 includes drive shafts 401 fixedly connected to both ends of the conveying roller 3. An adjusting ring 402 is rotatably connected to the outer wall of the drive shaft 401 and within the mounting seat 1. A sliding plate 403 is fixedly connected to the bottom of the adjusting ring 402. A pressing block 404 is slidably connected to the bottom of the adjusting ring 402 and within the mounting seat 1. A push rod 405 is rotatably connected to the outer wall of the pressing block 404. An electric push rod 406 is fixedly connected to the outer wall of the push rod 405. A connecting rod 407 is rotatably connected to the outer wall of the adjusting ring 402 on the side far from the pressing block 404.

A pressing spring 409 is fixedly connected to the outer wall of the pressing plate 408 on the side of the entertainment adjusting ring 402. A sliding seat 410 is rotatably connected to the outer wall of the drive shaft 401 on the side far from the conveying roller 3. A drive motor 411 is fixedly connected to the inside of the sliding seat 410. A displacement sensor 412 is fixedly connected to the inside of the sliding seat 410;

[0031] Among them, the sliding plate 403, the adjusting ring 402, and the extrusion block 404 are all made of ABS plastic. The sliding plate 403 and the extrusion block 404 are both designed with a conical structure.

The connection methods of the electric push rod 406, the drive motor 411, and the displacement sensor 412 with the controller 5 are all electrical connections. When the controller 5 starts the electric push rod 406, the electric push rod 406 will push the extrusion block 404 to move inward. The inward-moving extrusion block 404 will push the adjusting ring 402 to move outward through the sliding plate 403. The outward-moving sliding plate 403 will drive the two conveying rollers 3 to move away from each other through the drive shaft 401. When the distance between the conveying rollers 3 is adapted to the thickness of the label paper, the controller 5 turns off the electric push rod 406, and the electric push rod 406 no longer pushes the extrusion block 404 to move, and the two conveying rollers 3 no longer move away from each other. The controller 5 starts the drive motor 411, and the drive motor 411 drives the conveying rollers 3 to rotate through the drive shaft 401.

The controller 5 calculates the moving distances of the guiding piece 203 and the conveying roller 3 according to the input data;

[0033] The controller 5 starts the adjusting motor 210. The adjusting motor 210 drives the worm gear 209 to drive the worm wheel 208 and the winding shaft 206 to rotate. The rotating winding shaft 206 will release the traction rope 205. The released traction rope 205 no longer pulls the sliding frame 202, and the pushing spring 207 will push the sliding frame 202 to move inward. The inward-moving sliding frame 202 will drive the two guiding pieces 203 and the deviation rectifying rod 204 to move closer to each other. When the distance between the guiding piece 203 and the deviation rectifying rod 204 is adapted to the width of the label paper, the controller 5 turns off the adjusting motor 210. The adjusting motor 210 does not drive the winding shaft 206 to rotate, and the winding shaft 206 no longer releases the traction rope 205, and the sliding frame 202 no longer drives the guiding piece 203 and the deviation rectifying rod 204 to move. The controller 5 starts the electromagnet 212, and the electromagnet 212 will fixedly adsorb the sliding frame 202 in the mounting seat 1;

[0034] The controller 5 activates the electric push rod 406. The electric push rod 406 will push the extrusion block 404 to move inward. The inward-moving extrusion block 404 will push the adjustment ring 402 to move outward through the sliding plate 403. The outward-moving sliding plate 403 will drive the two groups of conveying rollers 3 to move away from each other through the drive shaft 401. When the distance between the conveying rollers 3 is adapted to the thickness of the label paper, the controller 5 turns off the electric push rod 406. The electric push rod 406 no longer pushes the extrusion block 404 to move, and the two groups of conveying rollers 3 no longer move away from each other. The controller 5 activates the drive motor 411. The drive motor 411 drives the conveying rollers 3 to rotate through the drive shaft 401;

[0035] Place the label paper into the conveying rollers 3. The rotating conveying rollers 3 will send the label paper into the inlet of the printing machine. The guiding piece 203 and the deviation-correcting rod 204 will prevent the label paper from shifting during the conveying process.
