[0022] A conveying device 12 is installed inside the installation groove 11, and limiting plates 13 are symmetrically and fixedly connected inside the installation groove 11 near the conveying device 12.

[0023] By adopting the above technical solution, the conveying device 12 is provided to replace manual work for feeding packaging bags.

[0024] An electric cylinder 21 is fixedly installed near the top of the end of the column 2 away from the U-shaped mounting frame 3, and the output end of the electric cylinder 21 is fixedly connected to the U-shaped sliding plate 22.

[0025] By adopting the above technical solution, the electric cylinder 21 is operated, so that the fixedly connected U-shaped slide plate 22 is lifted and lowered.

[0026] On the other side between the inner walls of the U-shaped mounting frame 3, a first lead screw 35 is rotatably connected, and the sliding frame 34 is in threaded rotational connection with the first lead screw 35. A cross-shaped rotating rod 36 is rotatably connected near the first lead screw 35 between the inner walls of the U-shaped mounting frame 3.

[0027] By adopting the above technical solution, the first lead screw 35 rotates, thereby causing the sliding frame 34 in threaded rotational connection to move.

[0028] One end of the sliding frame 34 close to the first lead screw 35 and near the top is fixedly connected with an L-shaped plate 38. A first helical gear 39 is rotatably connected to the side end of the L-shaped plate 38, and the side end of the second lead screw 37 penetrates through the L-shaped plate 38 and is fixedly connected with the first helical gear 39.

[0029] By adopting the above technical solution, the first helical gear 39 rotates, thereby causing the fixedly connected second lead screw 37 to rotate.

[0030] A U-shaped seat 310 is fixedly connected to the side end of the sliding frame 34 and below the L-shaped plate 38. A cross-shaped sliding sleeve 311 is slidably connected to the outer circle of the cross-shaped rotating rod 36, and the cross-shaped sliding sleeve 311 is rotatably sleeved inside the U-shaped seat 310. A second helical gear 312 is fixedly connected to the outer circle of the cross-shaped sliding sleeve 311, and the second helical gear 312 meshes with the first helical gear 39.

[0031] By adopting the above technical solution, the cross-shaped rotating rod 36 rotates, thereby causing the cross-shaped sliding sleeve 311 to drive the second helical gear 312 to rotate.

[0032] A second motor 32 is fixedly installed near one side of the side end of the U-shaped mounting frame 3. The output end of the second motor 32 penetrates through the U-shaped mounting frame 3 and is fixedly connected with the first lead screw 35.

[0036] Working principle: When this device is in use, first, the packaging bag to be labeled can be placed on the conveying device 12. Then, the conveying device 12 is operated. When the packaging bag moves under the U-shaped mounting frame 3, it can be stopped. Then, the electric cylinder 21 can be operated, so that the U-shaped sliding plate 22 moves downward under the action of the column 2 until the labeling device body 314 touches the packaging bag, thereby realizing the work of adjusting the height of the labeling device body 314, and solving the problem that it is not convenient to adjust the height and thus it is impossible to be applicable to labeling packaging bags of different sizes.

[0037] By operating the first motor 31, the fixedly connected cross-shaped rotating rod 36 rotates. Then, under the action of the cross-shaped sliding sleeve 311, the second helical gear 312 is driven to rotate, thereby making the meshing-connected first helical gear 39 rotate, and then making the fixedly connected second lead screw 37 rotate. Thus, the bracket 313 connected by screw rotation drives the labeling device body 314 to move horizontally. By operating the second motor 32, the fixedly connected first lead screw 35 rotates, so that the sliding frame 34 connected by screw rotation drives the labeling device body 314 to move longitudinally, thereby realizing the effect of driving the labeling device body 314 to move at multiple angles, and further solving the problem that the position where the label is pasted cannot be flexibly controlled.

[0038] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model also intends to include these modifications and variations.
