Description

Technical Field

[0001] This utility model relates to the field of high-barrier antistatic corrugated cardboard box preparation technology, specifically a cardboard box conductive coating mechanism. Background Technology

[0002] With the rapid development of industries such as electronics, pharmaceuticals, and food, the requirements for packaging materials are becoming increasingly stringent. High barrier properties can effectively prevent the intrusion of oxygen, water vapor, etc., and extend the shelf life of products, while antistatic properties can prevent static electricity from damaging precision electronic components and ensure product quality and safety.

[0003] A Chinese patent with publication number CN222607002U discloses a conductive adhesive coating device. This device utilizes a flipping mechanism with gears and racks. After the top of the conductive material is coated with adhesive by the right-side coating mechanism, it continues to move to the left. When the conductive material passes a fan, it is quickly solidified by the airflow. When the gear passes the rack, it rotates 180 degrees, causing the conductive material to rotate 180 degrees as well. When the conductive material moves to the left-side coating mechanism, the left-side coating mechanism can then coat the other side of the conductive material with adhesive. This allows for coating both sides of the conductive material in a single pass, improving coating efficiency.

[0004] In the aforementioned literature, existing coating equipment can only coat a single material at a time and requires frequent loading and unloading operations, resulting in poor production continuity, cumbersome operation, and serious impact on production efficiency. Therefore, a conductive coating mechanism for cardboard boxes is proposed to address these issues. Utility Model Content

The roller coating assemblies 2 and hot air blowers 19 located at the upper part are arranged sequentially along the feeding direction of the upper truss 112 and are located directly above the multiple first conveyor shafts 16.

[0019] The roller coating assembly 2 includes side plates 21 fixed on both sides of the lower truss 12 or the upper truss 112. A roller coating shaft 29 and a scraper shaft 28 are rotatably mounted between the side plates 21, and the scraper shaft 28 rolls against the curved surface of the roller coating shaft 29. The scraper shafts 28 in the two roller coating assemblies 2 are located on the side of their corresponding roller coating shafts 29 facing the feed end.

[0020] The feeding assembly 4 includes two brackets 41 fixed on two side plates 21 inside the upper roller coating assembly 2. A material distribution groove 42 is fixed between the brackets 41. Multiple drip ports 43 are arranged horizontally below the material distribution groove 42, and the discharge ends of the multiple drip ports 43 are directly opposite the rolling contact point of the scraper shaft 28 and the roller coating shaft 29. A flow valve 44 is fixed on each drip port 43.

[0021] The overflow assembly 3 includes a liquid delivery pipe 32 that is fixed through the storage tank 110. An overflow groove 31 is fixed at the top of the liquid delivery pipe 32. The overflow groove 31 is fixed between two side plates 21 located in the lower roller coating assembly 2. The overflow groove 31 is fastened to the outer side of the lower part of the rolling surface of the lower roller coating shaft 29. An overflow channel 34 is fixed at the upper part of the overflow groove 31. The bottom end of the overflow channel 34 is connected to and fixed on the storage tank 110. The bottom end of the liquid delivery pipe 32 extends into the bottom of the storage tank 110. A second pump 33 is fixed on the liquid delivery pipe 32.

[0022] Each side plate 21 has a sliding groove 22, and a slider 23 is slidably disposed in each sliding groove 22. The scraper shaft 28 is rotatably installed between the sliders 23 on both sides. Each slider 23 is fixedly connected to a threaded sleeve 25 by a connecting rod 24. Each threaded sleeve 25 is rotatably provided with a lead screw 26 threadedly connected to it. The lead screw 26 is rotatably mounted on the corresponding side plate 21. The end of the rotation center shaft of the lead screw 26 is connected to a motor 27, and the motor 27 is fixed on the corresponding side plate 21.

[0023] The storage tank 110 is connected to a No. 1 pump 111 via a pipe on its side, and the No. 1 pump 111 is fixed on the base plate 1. The liquid outlet of the No. 1 pump 111 is connected to the distribution tank 42 via a hose.

[0024] The rotating end of the roller coating shaft 29 located in the lower truss 12 is connected to multiple first conveyor shafts 16 and first end shafts 15 via chains. The rotating end of the roller coating shaft 29 located in the upper truss 112 is connected to multiple second conveyor shafts 18 and second end shafts 17 via chains.

[0025] During operation, existing coating equipment can only coat a single material at a time and requires frequent loading and unloading operations, resulting in poor production continuity, cumbersome operation, and serious impact on production efficiency. In this solution, the distance between the upper truss 112 and the lower truss 12 is adjusted by controlling the extension and retraction of the hydraulic rod 13. When the distance between the lower truss 12 and the upper truss 112 changes, the distance between their internal structures also changes accordingly, thus making it suitable for processing paperboard of different thicknesses. By synchronously driving the first end shaft 15 and one of the second conveyor shafts 18 in the upper truss 112 and lower truss 12 respectively, the roller coating shafts 29 in the lower truss 12 and upper truss 112 are driven synchronously under the synchronous transmission of the chain. Multiple first conveyor shafts 16 and multiple second conveyor shafts 18 are also driven synchronously. By controlling the operation of the second pump 33 and the first pump 111, the paint in the storage tank 110 is pumped into the overflow trough 31 and the distribution trough 42 respectively. When the paint is pumped into the overflow trough 31, the lower part of the roller coating shaft 29 is coated by the paint in the overflow trough 31. The coating material is submerged, and under the rotation of the inner roller coating shaft 29, the lower roller coating shaft 29 will be evenly coated with coating material. Due to the rolling contact between the lower scraper shaft 28 and the roller coating shaft 29, excess coating material will be scraped off to ensure that the coating material on the lower roller coating shaft 29 is evenly thick. The coating material in the distribution groove 42 will drip from the drip outlet 43 onto the rolling contact area between the roller coating shaft 29 and the scraper shaft 28. Similarly, under the rolling pressure of the scraper shaft 28, excess coating material is left at the rolling contact area between the upper roller coating shaft 29 and the scraper shaft 28, while the upper roller coating shaft 29... With uniform coating thickness, the cardboard is placed between the feed ends of the lower truss 12 and the upper truss 112. It is then fed forward by the No. 2 end shaft 17 and the No. 1 conveyor shaft 16 located below it. As the cardboard passes under the upper roller coating shaft 29, the coating on the upper roller coating shaft 29 is transferred to the upper surface of the cardboard. With the continuous conveying of multiple No. 1 conveyor shafts 16, the cardboard passes under the upper hot air blower 19. The hot air blown from the upper hot air blower 19 dries the coating on the upper surface of the cardboard. As the cardboard continues to advance to the lower roller coating... When the cardboard is above component 2, under the constraint of multiple second conveyor shafts 18, the coating on the lower roller coating shaft 29 will be transferred to the lower surface of the cardboard, thereby completing the double-sided coating of the cardboard. As the first conveyor shaft 16 continues to convey the cardboard, it will be conveyed to the upper part of the lower hot air blower 19. Under the action of the hot air blown out by the lower hot air blower 19, the cardboard will be lifted and adhered to the lower part of multiple second conveyor shafts 18, and the coating on the lower part of the cardboard will be dried. Then, double-sided coating and double-sided drying will be carried out. Finally, the processed cardboard will be discharged from between the first end shaft 15 and the second conveyor shaft 18 on the far side. In this process, by controlling the operation of motor 27 located at the same height, two lead screws 26 are driven respectively. When the lead screws 26 rotate, under the restriction of connecting rod 24, they will drive the threaded sleeves 25 on them to translate, thereby driving the slider 23 to slide in the groove 22. When the slider 23 slides, it will drive the scraper shaft 28 to move, thereby adjusting its rolling gap with the roller coating shaft 29, so that different thicknesses of coating can be applied to the substrate to meet different processing requirements. In summary, the paperboard is coated and dried on both sides by the roller coating assembly 2 and the hot air blower 19, which are staggered in the lower truss 12 and the upper truss 112, and continuous feeding processing is possible, which effectively improves production efficiency. It achieves the effect of conductive coating, is more convenient to operate than traditional coating mechanisms, and can continuously feed materials, effectively improving production efficiency.
