Description

Technical Field

[0001] This utility model relates to the field of cardboard production technology, and more specifically, to a compaction device for cardboard labeling. Background Technology

[0002] Paperboard, also known as board paper, is a thick sheet of paper made from various pulps and composed of interwoven fibers. The difference between paperboard and paper is usually distinguished by basis weight and thickness. Generally, paperboard with a basis weight of more than 250g / m2 and a thickness of more than 0.5mm is called paperboard. Paperboard is usually printed to improve its appearance, but there are also practices of changing the appearance and displaying information by pasting stickers.

[0003] Stickers on cardboard surfaces are typically applied manually and then compacted. A search revealed application CN202022487167.9, entitled "A Sticker Compacting Device for Decorative Boards." This application addresses the shortcomings of current sticker compaction methods. It utilizes an electric motor to roll a pressure roller from one end of the board to the other, facilitating the removal of air from the board. A hydraulic rod then applies secondary compaction with a pressure plate, improving the compaction effect. However, in practical use, when the sticker edge near the pressure roller curls up, the roller's direct, open-end rolling action can press the curled edge tightly, creating a folded edge and even causing the sticker to stick to the roller surface, affecting the finished product quality. Further improvements are needed. Additionally, the application requires manual positioning of the board using limit blocks, making board handling cumbersome and requiring further refinement.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0029] According to an embodiment of the present invention, a compaction device for cardboard stickers is provided.

[0030] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4As shown, a cardboard sticker compaction device according to an embodiment of the present invention includes a conveying chamber 1 and a top chamber 4. The top chamber 4 is fixedly installed on the top surface of the conveying chamber 1, and a drive roller 2 is rotatably connected inside the conveying chamber 1. A conveyor belt 3 is sleeved on the outside of the drive roller 2. The top chamber 4 is equipped with a first compaction mechanism 9 and a second compaction mechanism 10. The first compaction mechanism 9 and the second compaction mechanism 10 have the same structure and are arranged vertically to complete compaction operations in two directions respectively. The first compaction mechanism 9 includes a lifting frame 11, an electric cylinder 13, and a moving frame 20. The electric cylinder 13 is fixedly connected to the top surface of the conveying chamber 1, and the bottom surface of the moving rod of the electric cylinder 13 is flush with the top surface of the lifting frame 11. The lifting frame 11 is fixedly connected to the surface. A positive and negative threaded rod 15 is rotatably connected inside the lifting frame 11. A movable frame 20 is provided inside the lifting frame 11, symmetrically distributed along the center position of the positive and negative threaded rods 15. The positive and negative threaded rods 15 pass through the movable frame 20 and are threadedly connected to it. A roller frame 21 is provided below the movable frame 20, and a pressure roller 22 is rotatably connected to the inner side of the roller frame 21. The pressure roller 22 is a rubber roller.

A top plate 25 is fixedly installed on the top surface of the connecting rod 24, limiting the connecting rod 24 to prevent it from detaching from the movable frame 20. A first servo is fixedly connected to one end of the lifting frame 11. A servo motor 16 is installed inside the conveying chamber 1, and the output end of the first servo motor 16 is fixedly connected to one end of the positive and negative threaded screw 15. A pressure box 5 is fixedly installed inside the conveying chamber 1, and a suction port 6 is opened on the top surface of the pressure box 5. The top surface of the pressure box 5 slides against the conveyor belt 3. An air pump 7 is installed below the conveying chamber 1, and the input end of the air pump 7 is connected to the pressure box 5 through an air extraction pipe 8. The first compaction mechanism 9 and the second compaction mechanism 10 have the same structure and are arranged vertically. The cardboard with the sticker is conveyed by the conveyor belt 3 and enters the area below the first compaction mechanism 9. The electric cylinder 13 of the first compaction mechanism 9 extends, pushing the pressure roller 22 of the first compaction mechanism 9 to move down and abut against the sticker. The first compaction... The first servo motor 16 of mechanism 9 drives the positive and negative threaded screws 15 to rotate, which in turn drives the moving frame 20 of the first compaction mechanism 9 to move outward simultaneously, and drives the pressure roller 22 of the first compaction mechanism 9 to move outward simultaneously, rolling and compacting the sticker longitudinally from the inside to the outside at the same time, so as to prevent the longitudinal edge of the sticker from curling up. Similarly, when the cardboard moves to the bottom of the second compaction mechanism 10, the pressure roller 22 of the second compaction mechanism 10 rolls and compacts the sticker laterally from the inside to the outside at the same time, so as to prevent the lateral edge of the sticker from curling up. Through two rolling and compaction, the compaction stability is higher. At the same time, it avoids the problem that the curling edge is easily folded and pressed tightly by unidirectional compaction, improves the stability and reliability of compaction, prevents the occurrence of curling edge stability, and improves the yield.

[0031] In one embodiment, a first guide rod 12 is fixedly installed on the top surface of the lifting frame 11, and the first guide rod 12 passes through the top compartment 4 and is slidably connected to the top compartment 4. The first guide rod 12 stabilizes the lifting of the lifting frame 11.

[0032] In one embodiment, a second guide rod 14 is fixedly installed inside the lifting frame 11, and the second guide rod 14 passes through the movable frame 20 and is slidably connected to the movable frame 20, thereby stabilizing the movement of the movable frame 20.

[0033] In one embodiment, the positive and negative threaded rods 15 pass through both ends of the lifting frame 11 and are rotatably connected to both ends of the lifting frame 11 via bearings, thereby improving the stability of rotation.

[0034] In one embodiment, a pressure sensor 23 is fixedly installed on the bottom surface of the lifting frame 11, and the detection end of the pressure sensor 23 abuts against the top surface of the roller frame 21. The output end of the pressure sensor 23 is electrically connected to the input end of the electric cylinder 13 through the controller 19.

An observation window 18 is provided on the front facade of the top compartment 4. The controller 19 is convenient for operators to operate, and the observation window 18 is convenient for operators to observe the position of the cardboard conveying.

[0036] In one embodiment, a second servo motor 17 is fixedly installed on the front facade of the conveying bin 1, and the output end of the second servo motor 17 is fixedly connected to one end of the roller shaft of the drive roller 2, which is a common drive structure.

[0037] In one embodiment, multiple sets of suction ports 6 are densely distributed at equal intervals, and the suction ports 6 are located below the first compaction mechanism 9 and the second compaction mechanism 10. When conveying the cardboard, the vacuum pump 7 extracts the air from the pressure box 5, so that the suction ports 6 are in a negative pressure suction state. The conveyor belt 3 has densely opened through holes, and the through holes at the suction ports 6 also generate a negative pressure effect, which can hold the cardboard, prevent the cardboard from moving randomly, stabilize the conveying of the cardboard, and complete the function of automatically fixing the cardboard, eliminating the need for manual limiting and improving the convenience of use.

[0038] Working principle:

[0039] The first compaction mechanism 9 and the second compaction mechanism 10 have the same structure and are arranged vertically. The cardboard with the sticker is conveyed by the conveyor belt 3 and enters below the first compaction mechanism 9. The electric cylinder 13 of the first compaction mechanism 9 extends, pushing the pressure roller 22 of the first compaction mechanism 9 to move down and abut against the sticker. The first servo motor 16 of the first compaction mechanism 9 drives the positive and negative threaded screws 15 to rotate, which in turn drives the moving frame 20 of the first compaction mechanism 9 to move outward at the same time, and drives the pressure roller 22 of the first compaction mechanism 9 to move outward at the same time, rolling and compacting the sticker longitudinally from the inside to the outside at the same time to prevent the longitudinal edge of the sticker from curling up. Similarly, when the cardboard moves to below the second compaction mechanism 10, the pressure roller of the second compaction mechanism 10... 22. The sticker is rolled and compacted horizontally from the inside out simultaneously to prevent the horizontal edges of the sticker from curling up. Through two rolling and compaction processes, the compaction stability is higher. At the same time, it avoids the problem of curling edges being folded and pressed tightly, which is easy to cause with unidirectional compaction. This improves the stability and reliability of compaction, prevents curling, and increases the yield rate. Meanwhile, the top surface of the pressure box 5 has a suction port 6. When the cardboard is conveyed, the air pump 7 extracts the air from the inside of the pressure box 5, so that the suction port 6 is in a negative pressure suction state. The surface of the conveyor belt 3 is densely covered with through holes. The through holes at the suction port 6 also generate a negative pressure effect, which can hold the cardboard and prevent it from moving around. This stabilizes the conveying of the cardboard and completes the function of automatically fixing the cardboard, eliminating the need for manual limiting and improving the convenience of use.
