Description

Technical Field

[0001] The utility model relates to the technical field of labeling machines, in particular to a packaging box labeling mechanism. Background Art

[0002] A labeling machine is a mechanical device that uses an electromechanical control mechanism to stick and adhere labels to manually predetermined positions to achieve the purpose of packaging. During the processing of packaging boxes, a labeling machine is needed to stick the labels on the top of the packaging box.

[0003] The utility model patent with authorization announcement number CN215827163U discloses a labeling device for polyethylene wax powder packaging boxes, which includes a frame body, a marking part installed on the frame body, a pressing part fixed above the marking part and a transmission device arranged below the frame body; and an inclined platform is fixed on the top of the transmission device below the marking part, and an operating panel for supporting the packaging box is fixed on one side of the inclined platform, and the pressing part includes a pressing cylinder fixed on the frame body; wherein the packaging box labeled by the marking part contacts the pressing cylinder through the operating panel to enhance the label adhesion. After the packaging box surface is labeled by the marking part, the packaging box is placed on the operation plate. At this time, the label pressing part stirs and squeezes the labeling surface of the packaging box. At the same time, the soft cylinder is compressed, and the supporting spring cylinder is deformed, so that the convex balls will contact the labeled packaging box through the soft cylinder, so that the staggered convex balls act evenly on the surface of the packaging box, avoiding extrusion dead corners and preventing the sharp corners of the label from curling up, so that the label is fully bonded to the packaging box, avoiding label falling off during transportation and sales, and enhancing labeling stability.

[0004] Although the labeling equipment for polyethylene wax powder packaging boxes enhances labeling stability, the device still has the following problems in actual use: when labeling the packaging box, the device directly sticks the label on the top of the packaging box. If there is dust or other foreign matter on the top of the packaging box, the adhesion between the label and the packaging box will be poor, which may easily cause the label to fall off later. In view of this, we propose a packaging box labeling mechanism. Utility Model Content

[0005] The purpose of the present utility model is to provide a packaging box labeling mechanism to solve the problems raised in the above background technology.

A strip groove is provided at the top center of the movable plate 35; a movable seat 37 that can move horizontally is provided below the movable plate 35, and a brush 370 for cleaning the surface of the packaging box is fixed to the bottom of the movable seat 37; a support plate 372 is fixed at the top center of the movable seat 37, and the support plate 372 passes through the strip groove and is slidably connected to the strip groove, and a fixed block 38 is fixed at the top of the support plate 372. A rectangular groove 380 is provided on the outer wall of the fixed block 38, and a cam 39 is rotatably installed in the rectangular groove 380. A connecting shaft 390 is fixed to the cam 39, and a motor 36 for driving the connecting shaft 390 to rotate is installed on the front side of the cam 39.

[0033] In this embodiment, the support 30 and the support plate 32 are integrally formed, with the support 30 perpendicular to the support plate 32. This integral structure provides greater connection strength, ensuring a secure connection between the support 30 and the support plate 32 and providing effective support for the first electric cylinder 31.

[0034] In this embodiment, the cross-section of the bracket 1 is H-shaped, and the bracket 1 is fixedly connected to the frame of the conveyor 2 by bolts. The H-shaped bracket 1 plays a role in stably supporting and fixing the device.

[0035] In this embodiment, two lugs 350 are fixed to each end of the bottom of the movable plate 35, with a guide rod 351 fixed between the two lugs 350. Protrusions 371 are fixed to each side of the top of the movable seat 37, and the guide rods 351 pass through and are slidably connected to the protrusions 371. The provision of the guide rods 351 guides the horizontal movement of the movable seat 37, ensuring the stability of the movable seat 37 during horizontal movement.

The conveyor 2 is a device used to transport powder and granular materials horizontally, inclined, and vertically. The main structure includes components such as a motor, a transmission roller, a coupling, and a reducer; the labeling component 4 is the core part of the labeling machine, which is responsible for accurately attaching labels to products. The main structure includes a labeling head, a pressure device, and a peeling plate; the principles of the conveyor 2 and the labeling component 4 are well known to people in this field and will not be repeated here.

[0041] During specific use, the user first places the packaging box on the conveyor belt of the conveyor, and the conveyor belt drives the packaging box to move. When the packaging box moves to the bottom of the cleaning part 3, the user turns on the power of the motor 36, and the motor 36 starts to work. The output shaft of the motor 36 rotates to drive the connecting shaft 390 and the cam 39 to rotate. While the cam 39 rotates, it pushes the left and right side walls of the rectangular groove 380 back and forth. Under the action of the cam 39, the fixed block 38 reciprocates in the horizontal direction. The fixed block 38 also drives the support plate 372 and the movable seat 37 to reciprocate horizontally. The movable seat 37 drives the bristles 370 to reciprocate horizontally. The bristles 370 rub the top of the packaging box back and forth, and the dust on the top of the packaging box is cleaned. Finally, the conveyor belt drives the packaging box to move to the bottom of the labeling component 4 for labeling.
