[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] The utility model provides a technical solution:

[0019] See also Figure 1-4, a lifting structure of a label applicator, including a mobile base 1, a support column 2 installed on the mobile base 1, a lifting device is installed on one side of the support column 2, the lifting device includes a reciprocating screw 4, a slider of the reciprocating screw 4 is connected to a label applicator support arm 5, one side of the label applicator support arm 5 is connected to a support rod 6, and a downward distance sensor 6 is installed at the bottom of the support rod 7, the reciprocating screw 4 also includes a screw rod 42, a limit slide 43, and a servo motor 41, the slider is connected to the screw rod 42, and the slider limit slide 43 is slidably connected, the label applicator is installed on the label applicator support arm 5, when the distance sensor 6 recognizes the distance between it and the product, the signal is fed back to the control system, the control system calculates the distance between the label applicator and the product according to the height of the distance sensor 6 and the label applicator, thereby controlling the servo motor 41 and the reciprocating screw 4 to drive the label applicator to lift and lower, because the lifting stroke of the reciprocating screw 4 is limited, it is set to a two-stage lifting, specifically as follows:

[0020] Example 1

[0021] The lifting device also includes a vertical mounting frame 3, and the reciprocating screw 4 of the lifting device is installed in the mounting frame 3. There is a slide groove on the side of the bracket column 2, and a slider slides in the slide groove. The slider is fixed to the mounting frame 3, and the mounting frame 3 is fixed to the bracket column 2 by screws, that is, the height of the reciprocating screw 4 on the bracket column 2 can also be adjusted. When adjusting, the screws between the mounting frame 3 and the bracket column 2 are loosened, and the mounting frame 3 is manually pushed to lift on the bracket column 2 until it reaches the appropriate height, and then the screws are tightened. This is the first stage of lifting, and the second stage of lifting is the lifting on the reciprocating screw 4.
