Description

Technical Field

[0001] The present invention relates to the technical field of packaging boxes, and specifically to a surface coating device for packaging boxes. Background Art

[0002] In the packaging industry, the appearance and performance of packaging boxes are crucial for the market competitiveness of products. As a key process to improve the quality of packaging boxes, surface coating can endow packaging boxes with richer colors and lusters, enhance their wear resistance, corrosion resistance, scratch resistance and other properties, thereby extending the service life of packaging, reducing losses of products during transportation and storage, and also enhancing the attractiveness and sense of grade of products. Currently, the common surface coating technology for packaging boxes is mainly vacuum coating technology. It is in a vacuum environment, and metal or non-metal materials are evenly deposited on the surface of the packaging box substrate through physical or chemical methods to form an extremely thin and dense film. For example, in a high-vacuum environment, the coating material is heated to evaporate, and gaseous atoms or molecules are deposited on the surface of the packaging box to form a film. This method has simple equipment and low cost, and can deposit various metal films, but the adhesion and uniformity of the coating are relatively poor; For example, the publication number CN115519783A discloses a coating method for packaging boxes, which successively includes the following steps: S1: Temperature control: Select a laminating machine, place the packaging box to be laminated in the laminating drying channel of the laminating machine, control the laminating temperature of the pre-coated film to be 80 - 100 °C, then lower its temperature to 80 - 90 °C, and finally control the temperature to be 50 - 60 °C; S2: Set the laminating pressure: Control the pressure according to the material of the packaging box. If the fiber structure of the packaging box material is tight, the tightness is large, and the smoothness is high, set the pressure to be 180 - 200 kg; if the fiber structure of the packaging box material is loose, the tightness is small, and the surface is rough, set the pressure to be 190 - 220 kg; S3: Control the laminating speed: Control the laminating speed of the laminating machine to be 10 m / min - 100 m / min; S4: Embossing: After the laminating is completed, the box body enters the embossing device through the conveying system, and the embossing device embosses different patterns and textures on the surface of the box body. This coating method not only does not have the phenomena of wrinkles, curling and local blistering, but also has high working efficiency; Although the existing coating equipment can meet the usage needs, it still has the following deficiencies in use: Before coating, due to different materials, the surfaces of some packaging boxes are relatively rough, and the product quality during coating is low, and it is necessary to spray a surfactant. Also, the sizes of existing packaging boxes are inconsistent and need to be grouped and adjusted before surface coating, resulting in low efficiency and affecting the working efficiency. At the same time, the packaging box needs to be coated with a surfactant and then dried on the surface before being transported to the coating equipment for operation. This process not only consumes time and increases costs but also occupies a large amount of space, increasing the space cost. Summary of the Invention

[0003] The object of the present invention is to provide a surface coating device for packaging boxes, so as to solve the problems raised in the above-mentioned background technology. Due to different materials of existing packaging boxes before coating, the surfaces of some packaging boxes are relatively rough, resulting in low product quality during coating, and it is necessary to spray surfactant.

Detailed implementation manner

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1 - 8 , an embodiment provided by the present invention: A surface coating device for a packaging box, including an operation table 1 and a coating machine 3. The coating machine 3 is installed on the right side of the top of the operation table 1. A moving rail 11 is fixedly arranged at the front end of the table surface of the operation table 1, and a limiting rail 12 is fixedly arranged at the rear end of the table surface of the operation table 1. Two groups of blocking frames 13 are installed at the right end of the operation table 1. A drying mechanism 2 is installed on the left side of the top of the operation table 1. A storage part 6 is placed at the bottom of the drying mechanism 2. A hydraulic cylinder 4 is installed at the right end of the operation table 1. A moving mechanism 5 is installed on the rear wall of the operation table 1. The center left side of the moving mechanism 5 is connected to the storage part 6. Two placement frames 7 are placed inside the storage part 6. The front and rear ends of the bottom of the two placement frames 7 are respectively engaged with the rear end of the moving rail 11 and the front end of the limiting rail 12.

[0020] Further, a sliding groove 111 is opened at the top of the moving rail 11. The left end of the sliding groove 111 penetrates through the moving rail 11. A front rack plate 112 is fixedly arranged at the rear end of the moving rail 11. Through this design, it is convenient for the storage part to be installed and moved, thus saving time for manually coating the packaging box one by one. The bottom end of the limiting rail 12 is fixedly arranged on the table surface of the operation table 1. The limiting rail 12 is horizontally parallel to the moving rail 11. A rear rack plate 121 is fixedly arranged at the front end of the limiting rail 12. The sliding groove 111 in the moving rail 11 only allows a group of moving wheels 612 to move horizontally. Through this design, the shaking generated by the moving wheels 612 during movement is reduced, thereby improving stability. When the rear blocking plate 13 stops the movement of the storage box 61 when it moves to the rightmost position, the fixing plate 73 in the stopped storage box 61 is perpendicular to the bottom side of the top coating machine 3, reducing the positioning time and improving the accuracy. Through the moving rail 11 and the limiting rail 12, it is convenient for the storage part 6 to move, thus saving time for manually coating the packaging box one by one.

[0021] Furthermore, the drying mechanism 2 includes a dryer 21 and a controller 22. The dryer 21 is installed on the left side of the top of the operating table 1. Six groups of fans 23 are installed at the bottom of the dryer 21. The controller 22 is installed at the top of the dryer 21. The controller 22 can be used to remotely operate the dryer 21 when the bottom storage box 61 moves, thereby reducing the labor burden. The six groups of fans 23 can quickly dry the packaging boxes placed in the storage box 61 on the bottom side, which is convenient for subsequent coating processing.

[0022] As a further step of the present invention, the moving mechanism 5 includes a servo motor 51 and a threaded rod 53. The left end of the servo motor 51 drives the threaded rod 53 to rotate. The rear end of the servo motor 51 is installed at the front end of the limit block 52. The left end of the threaded rod 53 is sleeved with a limit sleeve 54. The limit sleeve 54 is installed on the left side of the rear end of the operating table 1. This design is beneficial to driving the threaded rod to rotate under the drive of the servo motor, thereby driving the installed storage parts and placement racks to move, and then the hydraulic cylinder installed at the bottom is pushed into the coating machine. This design is beneficial to the packaging box in the drying link and other central processes without a lot of manual operation, reducing safety hazards.

[0023] As a further step of the present invention, the storage component 6 includes a storage box 61 and a connecting component 62. The bottom side of the front end of the storage box 61 moves on the upper side of the movable rail 11. Connecting components 62 are threadedly fixed on both sides of the rear end of the storage box 61. The rear ends of the two groups of connecting components 62 move in the threaded rod 53. An inner square groove 601 is provided inside the storage box 61. Vertical rods 602 are fixed on the four sides of the inner square groove 601. Side blocks 611 are fixed at the front end of the storage box 61. Three groups of moving wheels 612 are fixed at the bottom end of the side blocks 611. The bottom end of the moving wheels 612 moves in the movable rail 11. A protruding block 613 is fixed at the left end of the storage box 61. The square groove and four groups of vertical rods provided inside can facilitate the placement of the rack vertically into the storage box, making it easy to lift and lower, and convenient for storage and retrieval.

[0024] Furthermore, the connecting piece 62 includes a long barrel nut 621 and a C-shaped block 622. The long barrel nut 621 is installed in the center of the threaded rod 53. The C-shaped block 622 is fixed to the front end of the long barrel nut 621. The center of the C-shaped block 622 is engaged with the protruding block 613. The C-shaped block 622 uses a bolt 623 to thread the protruding block 613. This design facilitates the rapid installation and disassembly of the storage box, and then the entire group can be replaced, thereby improving placement efficiency and saving time.

[0025] As a further aspect of the present invention, the placement rack 7 includes two sets of rotating members 71 and placement columns 72. The two sets of rotating members 71 are installed at the center of the fixed plate 73. The four sides of the fixed plate 73 are inserted outside the four vertical rods 602. Multiple sets of placement columns 72 are installed at the top of the rotating members 71. The rotating member 71 includes a fixed bearing 711 and a rotating shaft 712. The fixed bearings 711 are respectively installed on the front and rear sides of the center of the fixed plate 73. The rotating shaft 712 is inserted through the centers of the two fixed bearings 711. Fixed circular plates 713 are fixedly provided at the tops of the two rotating shafts 712. Gears 714 are fixedly provided at the bottoms of the two rotating shafts 712. The outer walls of the two gears 714 are respectively engaged with the front rack plate 112 and the rear rack plate 121. The placement columns 72 are fixedly provided at the tops of the two fixed circular plates 713 in a snowflake shape. Through this design, it is beneficial for the placement columns to place packaging boxes of different sizes for clamping, improving the applicability of the device.

[0026] Working principle: During operation, when coating is required, first apply a surfactant to the surface of the packaging box and then insert it on the upper side of the fixed circular plate 713 in sequence. Then, place the placement rack 7 with the packaging box and the storage part 6 as a whole at the left end of the operating table 1. Subsequently, insert the protruding block 613 fixed at the rear end of the storage box 61 into the center of the C-shaped block 622 and fix it with a bolt 623. The moving wheels 612 installed at the bottom side of the front section of the storage box 61 slide in the sliding groove 111 at the top of the moving track 11. Then, power on and start the servo motor 51 to drive the threaded rod 53 at the left end to rotate. The rotation of the threaded rod 53 can drive the long barrel nut 621 to move. The movement of the long barrel nut 621 can drive the storage box 61 installed with threads at the front end to move. When the storage box 61 moves to the bottom side of the drying mechanism 2, the controller 22 can power on and start the dryer 21 to work, and then six groups of fans are used to dry the storage box 61 at the bottom side. When the storage box 61 moves, the gears at the bottom ends of the two rotating shafts 712 are respectively engaged with the front rack plate 112 installed at the rear end of the moving track 11 and the rear rack plate 121 fixed at the front end of the limiting track 12 to rotate. The rotation of the two gears 714 can drive the rotating shafts 712 to rotate in the fixed bearings 711 fixed before and after the fixed plate 73. The rotation of the rotating shafts 712 can drive the fixed circular plate 713 at the top to rotate. The rotation of the fixed circular plate 713 can drive the placement column 72 with the packaging box inserted at the top to rotate and dry. When the storage box 61 moves to the right end, after being blocked by the blocking frame 13, the servo motor 51 stops working. Then, the hydraulic cylinder 4 at the bottom side works to vertically lift the fixed plate 73 and the rotating part 71 under the limitation of the vertical rod 602 to the bottom side of the coating machine 3 for coating treatment. After coating, start the hydraulic cylinder 51 to descend, which can drive the fixed plate 73 to vertically descend into the inner groove 601 inside the storage box 61. Then, power on and reverse-start the servo motor 51 to rotate and drive the threaded rod 53 to rotate in the reverse direction. The reverse rotation of the threaded rod 53 can drive the long barrel nut 621 to move leftward. The movement of the long barrel nut 621 can drive the storage box 61 connected at the front end to move leftward. When the storage box 61 moves leftward to the left end of the moving track 11, the protruding block 613 at the rear end of the storage box 61 can be directly disassembled from the C-shaped block 622 fixed at the front end of the long barrel nut 621. After taking out the packaging box, another group of storage boxes 61 can be reinstalled, or directly pull the fixed circular plate 713 to lift the whole set of rotating parts 71 and placement column 72 out of the storage box 61, and insert a new set of rotating parts 71, fixed plate 73 and the placed packaging box into the storage box 61 to repeat the previous operation. The above is only the preferred embodiment of the present invention and does not impose any form of limitation on the present invention; any ordinary technician in the industry can smoothly implement the present invention according to the description in the accompanying drawings and the above description; however, any slight changes, modifications and equivalent changes made by those skilled in the art within the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention;Meanwhile, any equivalent changes, modifications, and evolutions made to the above embodiments based on the substantial technology of the present invention still fall within the protection scope of the technical solutions of the present invention.
