During the material transmission process, the pressure plate will press on the top of the material to fix the material. However, this method of fixing the material is not stable enough. When labeling both sides of the material, the labeling mechanism will exert pressure on the surface of the material, causing the material position to move, thereby reducing the labeling quality.

[0017] In order to more clearly understand the above-mentioned purposes, features and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0018] like Figure 1 - Figure 4The double-sided labeling equipment shown includes a labeling machine 1, a pressure plate frame 2 is arranged directly above the internal conveyor belt of the labeling machine 1, a fixed pressure plate 3 is arranged parallel to the inside of the pressure plate frame 2, and a reinforcement plate 4 is fixedly connected to the top of the fixed pressure plate 3 and the inner wall of the pressure plate frame 2. A positioning mechanism is arranged inside the pressure plate frame 2 and between the double-sided film-laminating mechanisms. By arranging the positioning mechanism inside the pressure plate frame 2, and the positioning mechanism is above the two labeling mechanisms, when the material moves to the bottom of the positioning mechanism, the movable roller 8 inside the positioning mechanism will move closer to the fixed roller 7 to clamp the material, thereby ensuring the stability of the material position and the labeling quality during double-sided labeling.

[0019] The positioning mechanism includes a fixed block 5, which is fixedly mounted on the inner wall of the pressure plate frame 2. A movable plate 6 is provided on one side of the fixed block 5. Two fixed rollers 7 are symmetrically mounted on the bottom of the fixed block 5. Two movable rollers 8 are symmetrically mounted on the bottom of the movable plate 6. Two slots 9 are symmetrically provided on the surface of the fixed block 5. Two plug posts 10 are symmetrically provided on the surface of the movable plate 6. The two plug posts 10 correspond to the two slots 9 respectively. The material is transported by the conveyor belt, and one side of the surface of the material to be labeled is brought close to the fixed roller 7. When the material moves between the fixed roller 7 and the movable roller 8 through the conveyor belt, the movable roller 8 will move closer to the fixed roller 7 to clamp the material, thereby ensuring the stability of the material position and the labeling quality during double-sided labeling. At the same time, with the cooperation of the plug posts 10 and the slots 9, the stability of the movable plate 6 during movement can be guaranteed.

[0020] A lifting plate 11 is provided between the fixed block 5 and the movable plate 6. A lifting rod 12 is fixedly installed at the middle end of the top of the lifting plate 11. A connecting frame 16 is fixedly provided on the top of the movable plate 6. A connecting rod 15 is installed inside the connecting frame 16 through a rotating shaft. A card slot is provided at the other end of the connecting rod 15. The top of the lifting rod 12 is rotatably installed in the card slot through the rotating shaft. A movable column 17 is installed on the outer surface of one end of the card slot of the connecting rod 15. Two side frames 13 are symmetrically provided inside the pressure plate frame 2. The two side frames 13 are symmetrically provided inside the pressure plate frame 2. 3 is located above the upper lifting rod 12, and a side groove 14 is formed on the surface of the side frame 13. The movable column 17 is movably engaged in the side groove 14. When the material moves between the fixed roller 7 and the movable roller 8 through the conveyor belt, the top of the material has an upward squeezing effect on the lifting plate 11. After the lifting plate 11 is lifted, the upper lifting rod 12 will move upward. At the same time, the upper lifting rod 12 will drive the movable plate 6 to move through the connecting rod 15. At this time, the movable plate 6 will move toward the fixed block 5 to achieve the clamping operation of the material.

[0021] The horizontal height of the lifting plate 11 is lower than that of the fixed pressure plate 3, and the end face of the lifting plate 11 is provided with a slope. The distance between the fixed pressure plate 3 and the conveyor belt is the height of the material. During the movement of the material, the end face of the material has an extrusion effect on the slope at the end of the lifting plate 11, so that when the material moves to the bottom of the lifting plate 11, the lifting plate 11 is squeezed and lifted upward.

[0022] Guide columns 18 are installed on the top of the lifting plate 11 and on both sides of the upper lifting rod 12. The surface of the guide column 18 passes through the pressure plate frame 2. A spring 19 is provided on the surface of the guide column 18, and the spring 19 is located between the lifting plate 11 and the pressure plate frame 2. Through the cooperation of the spring 19 and the guide column 18, the stability of the lifting plate 11 when moving up and down can be guaranteed. At the same time, the spring 19 has a downward pressure on the lifting plate 11, so that the lifting plate 11 has a certain extrusion force on the top of the material, which can further ensure the stability of the material when being double-sided labeled.

[0023] Working principle: First, the material is transported by the conveyor belt, and one side of the surface of the material to be labeled is placed close to the fixed roller 7. In the process of material movement, the end face of the material has an extrusion effect on the inclined surface of the end of the lifting plate 11, so that when the material moves to the bottom of the lifting plate 11, the lifting plate 11 is squeezed and lifted upward. After the lifting plate 11 is lifted, the upper lifting rod 12 will move upward. At the same time, the upper lifting rod 12 will drive the movable plate 6 to move through the connecting rod 15. At this time, the movable plate 6 will move toward the fixed block 5, and the movable roller 8 will move closer to the fixed roller 7 to clamp the material, ensuring the stability of the material position during double-sided labeling. At this time, the labeling mechanisms on both sides of the material can perform labeling operations on the material surface.
