[0022] The egg trays are placed in the discharge mechanism 3. When labeling, the discharge mechanism 3 transfers the egg trays to the conveyor belt 2 in sequence. After the egg trays are labeled by the labeling mechanism, they are sorted and collected in the receiving mechanism 4 to complete the entire process.

[0023] The labeling mechanism includes a header mechanism and an adjustment mechanism, and the adjustment mechanism is used to adjust the position of the header mechanism; the header mechanism includes a label plate 5, multiple guide rollers 6, a labeling plate 7 and a winding wheel 8, and a traction roller is provided between the labeling plate 7 and the winding wheel 8. The traction roller includes an adjacent rubber-coated roller 9 and a knurled aluminum roller 10, and the label paper passes between the rubber-coated roller 9 and the knurled aluminum roller 10; the header mechanism also includes a drive motor 26, and the drive motor 26 is connected to the winding wheel 8 and the knurled aluminum roller 10 via a synchronous belt 27, so that the winding wheel 8 and the traction roller rotate synchronously.

[0024] The labeling mechanism is provided with a traction roller, which adopts a combination of a rubber-coated roller 9 and a knurled aluminum roller 10 to increase the friction between the roller and the label paper. The knurled aluminum roller 10 is driven by a synchronous belt 27 to pull the label, making it easier to control the label output and label stop, thereby improving the labeling accuracy.

[0025] In order to adjust the labeling position, the adjustment mechanism includes a fixed seat 11 fixed on the frame 1, and an angle adjustment structure is provided on the fixed seat 11. The top of the angle adjustment mechanism is connected to a vertical lifting frame, and a sliding block 12 is slidably connected to the lifting frame. A horizontal mobile frame is provided on the sliding block 12, and the header mechanism is fixed on the mobile frame; the angle adjustment mechanism includes a bottom plate 13 provided on the fixed seat 11, a fixed plate 14 is provided on the bottom plate 13, and the lifting frame is provided on the fixed plate 14.

[0026] Due to the differences in the size of the egg trays, the position of the labeling plate 7 needs to be adjusted. The specific adjustment method is as follows:

[0027] Adjustment of labeling angle: Turning the first hand wheel 18 rotates the first lead screw 17, which changes the distance between the first connecting block 15 and the second connecting block 16, thereby changing the angle between the fixing plate 14 and the bottom plate 13, thereby causing the lifting frame to deflect, which is converted into an angle change of the labeling position;

[0028] Adjustment of the horizontal position: Move in parallel with the conveyor belt 2. Since the bottom plate 13 can slide on the fixed seat 11 and a fourth hand wheel 28 is provided on the fixed seat 11, rotating the fourth hand wheel 28 can drive the sliding of the bottom plate 13 to realize the movement of the labeling position in the direction parallel to the conveyor belt 2; Move in the blowing direction of the conveyor belt 2, rotate the third hand wheel 23, so that the third screw 24 rotates, driving the connecting plate 25 and the header mechanism to move in the direction perpendicular to the conveyor belt 2;

[0029] Height adjustment: Turn the second hand wheel 20 to rotate the second lead screw 21, driving the sliding block 12 and the header mechanism to move vertically up and down, thereby completing the height adjustment.

[0030] A more visual page design is set up on the equipment so that the operator can understand and learn to operate the equipment more quickly. Common troubleshooting solutions and precautions are provided so that the operator can accurately and quickly eliminate abnormalities and restore equipment operation.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] Unique label head design, the traction roller adopts a knurled aluminum roller and a rubber-coated drum to clamp the label, which increases friction when pulling the label and prevents slipping. At the same time, the winding wheel and the traction roller are driven synchronously by a synchronous belt. The knurled aluminum roller pulls the label, making it easier to control the accuracy of label output and label stopping.

[0033] The adjustment mechanism can accurately adjust the labeling position so that its position better matches the egg tray, thereby more accurately labeling the egg tray.
