[0040] See also Figure 1 , 2, 3, 6, the present invention provides a technical solution: an automatic label paper printing, detection and stacking machine, comprising a label printer 100, a label information detection module 200, a pressing and stacking mechanism 300 and an infrared sensor 5, wherein the label printer 100 is located at the very beginning of the entire machine, the label printer 100 is used to print information on the label paper, the label information detection module 200 is connected to the outlet of the label paper of the label printer 100, the label information detection module 200 is used to detect whether there are character errors and unclear printing problems in the information printed on the label paper, the pressing and stacking mechanism 300 is connected to the outlet of the label paper of the label information detection module 200, the pressing and stacking mechanism 300 is used to fold the label paper that has been detected correctly to form a stacked label paper product, the infrared sensor 5 is installed on the pressing and stacking mechanism 300 and is located on the conveying path of the label paper, the infrared light emitted by the infrared sensor 5 can be irradiated on the label paper, and can find the label paper with wrong information printed on it in cooperation with the label information detection module 200.

[0041] When the automatic label paper printing detection and stacking machine is working, the information to be printed is printed on the label paper through the label printer 100, and then the label paper with the printed information comes out from the outlet of the label printer 100 and enters the label information detection module 200. The label information detection module 200 uses visual detection technology to detect whether there are errors or defects in the information on the label paper. If errors or defects are detected in the information on a certain label paper, the label information detection module 200 will calculate the moving distance of the label paper. When the label paper reaches the position of the infrared sensor 5, the infrared sensor 5 emits an infrared ray pointing at the label paper, and the entire machine stops. After the staff processes it, if there is no error in the label paper, it will be transported to the pressing and stacking mechanism 300 for folding and collection.

[0042] See also Figure 4 , 5 The label information detection module 200 includes a support frame 201, a CCD camera 202 for visual detection is installed on the top of the support frame 201, and a light source box 203 for providing light for the CCD camera 202 during detection is installed in the middle of the support frame 201, an encoder 204 for calculating the position of each label paper is installed at the bottom of the support frame 201, and a photo sensing switch 205 for triggering the CCD camera 202 to take a photo is installed on one side of the encoder 204, a label support platform 206 is installed at the bottom of the support frame 201 and below the encoder 204, and two roller shafts 207 are installed on the top of the label support platform 206, and the label paper passes between the roller shaft 207 and the label support platform 206.

[0043] When the label information detection module 200 is working, the label paper passes between the roller shaft 207 and the label support platform 206. During the movement, the CCD camera 202 will detect the information on each label paper, and the light source box 203 will light up during the detection.

[0044] See also Figure 6 , 7 8.

[0045] When the lamination and stacking mechanism 300 is working, the feeding module 4 conveys the strip-shaped label paper to the traction and stacking module 2. Through the reciprocating motion of the traction and stacking module 2, the strip-shaped label paper is folded with equal length on the lamination and storage module 3 to form a label paper pile. As the label paper is continuously folded, the thickness of the label paper pile becomes thicker and thicker. The lamination and storage module 3 can self-adjust to achieve folding while moving downward, and the lamination and storage module 3 can laminar the label paper in the folding process to prevent folding deviation.

[0046] See also Fig. 9 , 10 The traction stacking module 2 includes a linear drive module 21 installed on the top of the base plate 1, a movable seat 22 is installed on the driving end of the linear drive module 21, a roller mounting frame 23 is installed on the top of the movable seat 22, the roller mounting frame 23 is internally rotatably connected with two label guide rollers 24, and rolling drive cylinders 25 are installed on both sides of the outside of the roller mounting frame 23, the telescopic end of the rolling drive cylinder 25 is downward, and a wheel frame 26 is installed, and the wheel frame 26 is internally rotatably connected with a rubber wheel 27.

[0047] When the traction stacking module 2 is working, the strip of label paper passes through the two label guide rollers 24 and the two rubber wheels 27 in sequence. At this time, the linear drive module 21 (the specific structure and principle are existing well-known technologies and will not be described in detail here) drives the movable seat 22, the mounting frame 23, the two label guide rollers 24, the rolling drive cylinder 25, the wheel frame 26 and the rubber wheel 27 to reciprocate synchronously, and cooperate with the feeding of the feeding module 4 to complete the folding of the strip of label paper into a label paper pile.

[0048] See also Fig.11 The pressing material storage module 3 includes a base seat 31 installed at the top of the bottom plate 1 and two cylinder mounting seats 32 installed at the top of the bottom plate 1. The base seat 31 is internally slidably connected to a plurality of guide rods 33. The bottom ends of the plurality of guide rods 33 extend to the bottom of the base seat 31 and are commonly connected to a motor mounting plate 34. The top ends of the plurality of guide rods 33 are commonly connected to a label folding material storage slot 35. A screw rod 36 is threadedly connected to the middle of the base seat 31. The driven end of the screw rod 36 is connected to a servo motor installed at the bottom of the motor mounting plate 34. The driving end of the machine 37 is connected, and baffles 38 are installed on the top of the base seat 31 and on both sides of the label folding storage slot 35. The top of the baffle 38 extends upward in the direction of the label folding storage slot 35 until it exceeds the highest position of the label folding storage slot 35. The inner sides of the two cylinder mounting seats 32 are installed with top cylinders 39. The telescopic ends of the top cylinders 39 are upward and are installed with double-station cylinders 310. The two telescopic ends of the double-station cylinders 310 are installed with pressure plates 311 for pressing the stacked label papers.

[0049] When the pressing and storing module 3 is working, when the strip label paper is led out from the rubber wheel 27, the free end of the label paper will be laid flat on the label folding storage slot 35. At this time, the double-station cylinder 310 on the left side is shortened, driving the two pressing plates 311 to approach, and then the top cylinder 39 is shortened to allow the pressing plate 311 to press the beginning of the label paper, and then the pulling stacking module 2 is used to reciprocate. Similarly, when the rubber wheel 27 carrying the label paper moves to the rightmost end, the pressing plate 311 on the right is pressed down, and the pressing plate on the left is pressed down. 311 is released, and then the folding end of the stacking module 2 is pulled back to reset, and the cycle is repeated. As the label paper is continuously stacked, the thickness becomes larger and larger. During the folding process, the servo motor 37 drives the screw rod 36 to rotate. Since the base seat 31 is fixed, under the reaction force, the motor mounting plate 34, the label folding storage trough 35, the screw rod 36, and the servo motor 37 will move downward as a whole to make room for the subsequent folding space. The baffles 38 on both sides are used to constrain the label paper from deviating during the folding process.

[0051] When the feeding module 4 is working, the free end of the label belt 45 passes through the driven roller group 42 and the active roller group 43 in sequence, and the driving motor 44 is started to drive the active roller group 43 to rotate, giving the label belt 45 a pulling force to move, so that the label belt 45 can move slowly to achieve feeding.
