Description

Technical Field

[0001] This utility model relates to the field of coloring devices for packaging boxes, specifically a coloring device for packaging boxes. Background Technology

[0002] The box-filling and coloring device is easy to operate and can quickly and evenly color various types of packaging boxes. It uses automatic spraying or roller brush technology, which can precisely control the color and coating thickness, supports multiple color switching, improves production efficiency while ensuring coloring quality, and is suitable for the personalized coloring needs of large-volume packaging boxes.

[0003] One existing coloring device for packaging boxes, as described in application number CN202220489456.9, includes a machine body with a conveyor belt at the top and a work frame mounted on one side of the top. An ink tank is mounted on the top of the work frame. Connecting seats are mounted on both sides of the bottom of a sliding plate, and coloring tubes are mounted at the bottom of the connecting seats. A drying chamber is mounted on the top of the machine body on one side of the work frame, and a heating tube is mounted at the upper part of the drying chamber. This coloring device for packaging box production quickly dries the painted packaging boxes by activating a circulating fan and heating tube to blow hot air into the lower part of the drying chamber. Simultaneously, residual hot air overflowing from the lower sides of the drying chamber is drawn into the drying chamber through a return air vent, where it is dried and dehumidified by a drying plate. The dried residual hot air is then returned to the drying chamber, achieving a circulating drying process and thus solving the problem of inconvenient rapid drying. The aforementioned device does not include a component for replacing the printhead. After prolonged use, the printhead is prone to damage or blockage, requiring replacement. However, existing devices cannot quickly remove the printhead for easy replacement later. Therefore, a coloring device for packaging boxes is proposed to address the above problem.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0016] Please see Figures 1-7As shown, a coloring device for packaging boxes includes a lower body 1; the top of the lower body 1 is fixedly connected to the upper body 2, the middle position of the bottom of the upper body 2 is fixedly connected to the top of the paint box 3, the bottom of the paint box 3 is fixedly connected to the top of the spray pipe 4, and a replacement mechanism is provided on the upper part of the lower body 1. The easy-to-replace mechanism includes a nozzle 10, the top of which is fixedly connected to the bottom of a fixed sleeve block 11. The front and rear ends of the bottom of the nozzle 4 are also fixedly connected to a first fixed plate 12. The fixed sleeve block 11 is also inserted into the outside of the first fixed plate 12 and the bottom of the nozzle 4, and the fixed sleeve block 11 is also slidably connected to the first fixed plate 12 and the nozzle 4. The first fixed plate 12 is a square design. During operation, pulling the nozzle 10 causes the fixing block 11 to move downwards. The inside of the fixing block 11 will move downwards along the outside of the nozzle 4 and the first fixing plate 12 until it is completely detached.

[0017] Furthermore, positioning blocks 13 are also inserted on the left and right sides inside the fixed sleeve 11, and the fixed sleeve 11 is slidably connected to the positioning blocks 13. The outer side of the positioning blocks 13 is fixedly connected to one end of the pressing rod 18, and the other end of the pressing rod 18 passes through the fixed sleeve 11 to reach the outer side of the fixed sleeve 11 and is fixedly connected to the pressing plate 19. The pressing rod 18 is slidably connected to the fixed sleeve 11, and the pressing rod 18 is a round rod design. During operation, press the pressing plates 19 on both sides of the fixing sleeve 11 above the nozzle 10 towards the center simultaneously. This causes the pressing plates 19 to move the pressing rod 18 along the fixing sleeve 11 into the fixing sleeve 11. As the pressing rod 18 moves, it pushes the positioning insert 13 towards the center until the positioning insert 13 is completely disengaged from the fixing sleeve 11.

[0018] Furthermore, the front and rear ends of the positioning plug 13 are also fixedly connected to the second fixing plate 14. The second fixing plate 14 is sleeved on the outside of the guide rod 15, and the guide rod 15 is slidably connected to the second fixing plate 14. The guide rod 15 is a round rod design. Support plates 16 are also provided at the left and right ends of the guide rod 15, and the guide rod 15 is fixedly connected to the side end of the support plate 16. The bottom end of the support plate 16 is fixedly connected to the top end of the first fixing plate 12. During operation, the positioning block 13 moves towards the center, causing the second fixing plate 14 to move along the outside of the guide rod 15 inside the support plate 16.

[0019] Furthermore, a return spring 17 is sleeved on the outside of the guide rod 15, and the left and right ends of the return spring 17 are respectively fixedly connected to the second fixing plates 14 on the left and right sides inside the fixing sleeve block 11. During operation, the second fixed plate 14 will compress the return spring 17 and retract as it moves.

[0020] Furthermore, the bottom end of the fixed sleeve 11 is fixedly connected to the bottom end of the second sealing block 21, the top end of the second sealing block 21 is inserted into the bottom end of the nozzle 4, and the second sealing block 21 is slidably connected to the nozzle 4. The inner wall of the fixed sleeve 11 near the lower position is fixedly connected to the outer side of the first sealing block 20, the inner wall of the first sealing block 20 is inserted into the nozzle 4, and the first sealing block 20 is slidably connected to the nozzle 4. Both the first sealing block 20 and the second sealing block 21 are made of rubber. When in operation, the nozzle 10 is pulled down, which causes the fixed sleeve 11 to move downward along the outer side of the bottom end of the nozzle 4. During the movement, the first sealing block 20 and the second sealing block 21 are gradually disengaged from the inside of the nozzle 4.

[0021] Furthermore, a caster wheel 22 is also provided at the bottom of the lower main body 1 near the corner, and the bottom of the lower main body 1 is fixedly connected to the top of the caster wheel 22. When in operation, pushing the lower body 1 of the device will drive the casters 22 at the bottom of the lower body 1 to move.

[0022] Working principle: First, press the pressing plates 19 on both sides of the fixing sleeve 11 above the nozzle 10 towards the center. This causes the pressing plates 19 to move the pressing rod 18 along the fixing sleeve 11 into the fixing sleeve 11. At the same time, as the pressing rod 18 moves, it pushes the positioning insert 13 towards the center until the positioning insert 13 is completely disengaged from the fixing sleeve 11. When the positioning insert 13 moves towards the center, it causes the second fixing plate 14 to move along the outside of the guide rod 15 inside the support plate 16. During the movement of the second fixing plate 14, it will compress the return spring 17 and retract it. Then, the nozzle 10 is pulled down, causing the fixing sleeve 11 to move downward along the outside of the bottom end of the nozzle 4. During the movement, the first sealing block 20 and the second sealing block 21 are gradually disengaged from the nozzle 4. At the same time, the fixing sleeve 11 moves downward, and the inside of the fixing sleeve 11 will move downward along the outside of the first fixing plate 12 until it is completely disengaged.
