[0027] Furthermore, the labeling mechanism 5 includes a pair of first guide rollers 51 fixedly installed on the side of the workbench 1, and a clamping member 53 for positioning the label tape is provided below the first guide rollers 51 through a slide rail 511. Round rods 52 are fixedly installed on both sides of the pair of first guide rollers 51 on the side of the workbench 1, and one end of the pair of round rods 52 is respectively slidably connected with a first guide plate 54 and a second guide plate 55, and the first guide plate 54 and the second guide plate 55 are used to guide the label tape.

[0028] It should be supplemented that the first material guide plate 54 and the second material guide plate 55 are threadedly connected with bolts, and the bolts can be pressed against the round rod 52 to achieve the function of fixing the first material guide plate 54 and the second material guide plate 55;

[0029] In order to ensure accurate labeling positioning, the position of the label tape needs to be adjusted. First, the first guide plate 54 and the second guide plate 55 are adjusted and fixed by the bolts, and the label tape is passed through the first guide rod 4 and the guide roller and then through the first guide plate 54 into the clamping member 53, and then bypasses the second guide plate 55 and is connected to the pulling roller 56 and the winding roller 57.

[0030] Furthermore, the driving assembly 8 includes a first motor 81 and a second motor 9 fixedly installed on the other side of the workbench 1. The side of the workbench 1 is rotatably connected to a pulling roller 56. The shaft ends of the first motor 81 and the pulling roller 56 pass through the workbench 1 and are respectively fixedly installed with a first pulley 82 and a second pulley 83. A transmission belt 84 is sleeved between the first pulley 82 and the second pulley 83. The side of the workbench 1 is rotatably connected to a winding roller 57, and the shaft end of the winding roller 57 is fixedly connected to the shaft end of the second motor 9.

[0031] The specific operation is that the first motor 81 and the second motor 9 drive the pulling roller 56 and the winding roller 57 to rotate, on the one hand to pull the label tape, and on the other hand to reel up the release paper after the label and the release paper are separated. After the label tape passes through the clamping member 53 and the first guide roller 51, it passes through other guide rollers and is clamped by the pulling roller 56 and then fixed to the winding roller 57.

[0032] In more detail, the clamping member 53 includes a pair of first support plates 531 slidably connected to the slide rail 511, the first support plate 531 is laterally slidably connected to the second support plate 533 through a slide groove 532, the second support plate 533 is longitudinally slidably connected to the clamping plate 535 through a guide groove 534, and the clamping plate 535 is arranged above the first guide roller 51 for clamping and positioning the label tape.

[0033] It should be added that the first support plate 531 and the second support plate 533 are both threadedly connected with bolts, and the bolts are used to adjust and fix the first support plate 531 and the second support plate 533, so that the clamping plate 535 can clamp and position the label belt.

[0039] Specifically, the label paper passes through the second material guide plate 55 and the separation plate 66, and under the action of the pressing roller 651 and the winding roller 57, the label tape is separated due to the tight contact of the separation plate 66;

[0040] Among them, the label and the release paper are separated by the action of the separation plate 66, the label is attached to the product, and the release paper passes through the pulling roller 56 and the guide roller and is rolled up by the winding roller 57. The stop block 68 is provided to facilitate the adjustment of the position of the second guide plate 55 so that the second guide plate 55 is in a suitable position to prevent the label tape from tilting and sticking crookedly.

[0041] Finally, a separation plate 66 is fixedly installed on the side of the workbench 1 below the first material guide plate 54, and a stop block 68 is slidably connected to one side of the separation plate 66 through a straight groove 67. The stop block 68 is fixed by bolts and can position the first material guide plate 54.

[0042] Working mode: When working, the product is placed in the fixture, and the feed rack 7 cooperates with the motor and the timing belt to drive the fixture so that the fixture comes to the bottom of the pressure roller 651 to prepare the label;

[0043] Then, the positions of the first support plate 531 and the second support plate 533 need to be adjusted to facilitate the clamping plate 535 to clamp and position the label tape, and then the clamp, the stop block 68 and the second guide plate 55 are adjusted to pull the label tape through the pulling roller 56 and the winding roller 57, and the label tape is separated from the release paper at the separation plate 66;

[0044] Finally, the cylinder 62 drives the connecting plate 64 and the pressing plate 65 to move downward so that the pressing roller 651 flattens the labels after the labels are separated.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
