[0002] Cardboard boxes are a common storage tool in people's daily work and life. However, it has been found that when cardboard boxes are stored for too long, the fruits, food, or other stored items inside will spoil and rot. Therefore, in order to prevent the stored items inside the cardboard boxes from spoiling or to slow down the spoilage rate, people often spray some coating liquid on the inner wall of the cardboard boxes. When spraying cardboard boxes, most of them require a spraying device and a positioning device. Existing spraying devices lack positioning functions, which may lead to deviations in the position of the cardboard box when spraying. This can cause the position of the cardboard box to not correspond to the nozzle during spraying, resulting in spraying errors and affecting the spraying quality. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a spraying device for carton processing with a cleaning mechanism. It solves the problem that most carton spraying devices require both a spraying device and a positioning device. Existing spraying devices lack positioning function, which may lead to deviations in the position of the carton during spraying. This results in the carton's position not corresponding to the spray head, causing spraying errors and affecting the spraying quality.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a spraying device for cardboard box processing with a cleaning mechanism, including a mounting base, a conveyor belt mechanism disposed inside the mounting base, a fixing buckle fixedly connected to the bottom end of the mounting base, a rotary motor fixedly connected to the bottom of the mounting base, an adjusting gear fixedly connected to the output end of the rotary motor, movable gears symmetrically disposed on the surface of the adjusting gears, the movable gears being slidably connected to the fixing buckle, and a movable rod fixedly connected to one end of the movable gears;

[0005] A guide frame is fixedly connected to one side of the movable rod. A mounting groove is opened on one side of the guide frame. A guide wheel is rotatably connected in the mounting groove. There are several guide wheels. Four support columns are fixedly connected to the top of the mounting base. A top plate is fixedly connected to the top of the four support columns. A fixing rod is fixedly connected to the top of the top plate. Two electric telescopic blocks are fixedly connected to the bottom of the fixing rod. A fixing plate is fixedly connected to the bottom of the two electric telescopic blocks through the top plate. Three buffer rods are slidably connected to the bottom of the fixing plate. Mounting columns are fixedly connected to both sides of the top of the mounting base.

[0006] As a further embodiment of this utility model: a buffer spring is sleeved on the outer arc surface of the buffer rod, the bottom ends of the three buffer rods are fixedly connected to the same cleaning roller brush, and the top ends of the three buffer rods are fixedly installed with limit strips through the fixing plate.

[0007] As a further embodiment of this utility model: a sliding groove is provided on one side of the mounting column, and a motor protection block is fixedly connected to one side of one of the mounting columns, and a servo motor is fixedly connected inside the motor protection block.

[0008] As a further embodiment of this utility model: a threaded rod is rotatably installed inside the sliding groove, and a second bevel gear is fixedly installed at the top end of the threaded rod.

[0009] As a further embodiment of this utility model: the second bevel gear is meshed with the first bevel gear, and a connecting shaft is fixedly installed between the two first bevel gears, and the connecting shaft is rotatably connected to the top of the mounting column.

[0010] As a further embodiment of this utility model: the output end of the servo motor is fixedly connected to one side of a first bevel gear, the surface of the threaded rod is provided with a movable seat, and a spray strip is fixedly installed between the two movable seats.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This carton processing spraying device with a cleaning mechanism, by setting up a conveyor belt mechanism, a guide frame, and a rotary motor, first places the carton onto the conveyor belt mechanism, and then uses the conveyor belt mechanism to move the carton. When the carton moves and contacts the front end of the guide frame, the rotary motor can be started to drive the adjusting gear and the upper and lower moving gear to move. Then, the moving gear drives the moving rod, the guide frame, and the guide wheel to move closer to the carton. When both guide wheels contact the carton, the guide wheels can be used to adjust the position of the carton until the carton is adjusted to be parallel to the bottom of the cleaning roller and spray bar, ensuring that there is no tilting or misalignment when spraying the top of the carton.

[0013] 2. This carton processing spraying device with a cleaning mechanism, by setting up a servo motor, a first bevel gear, a connecting shaft, and a second bevel gear, allows the servo motor in the motor protection block to be activated when the height of the spray bar needs to be adjusted. The output of the servo motor drives the first bevel gear to rotate. When the first bevel gear rotates, it simultaneously drives the connecting shaft to rotate, which in turn drives another first bevel gear to rotate. The first bevel gear meshes with the second bevel gear, which in turn drives the threaded rod to rotate. When the threaded rod rotates, it can drive the spray bar to adjust its height, making it convenient to adjust the spray bar to a suitable height for spraying the top of cartons of different heights.

[0014] 3. This carton processing spraying device with a cleaning mechanism, by setting up an electric telescopic block and a cleaning roller, allows the cleaning roller at the bottom to descend and contact the top of the carton when the carton moves under the cleaning roller. The cleaning roller cleans the top of the carton. At this time, not only can the cleaning roller clean the top of the carton, but the guide frames on both sides can also be used to position and adjust the carton so that it can be adjusted to the middle position of the conveyor belt mechanism. This avoids the presence of particulate impurities on the top of the carton when spraying the top, which would affect the spraying effect on the top of the carton. Attached Figure Description

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figure 1-3 As shown, this utility model provides a technical solution: a spraying device for carton processing with a cleaning mechanism, including a mounting base 1, a conveyor belt mechanism 2 is provided inside the mounting base 1, and a fixing buckle 5 is fixedly connected to the bottom end of the mounting base 1. By setting the fixing buckle 5, the moving gear 6 is fixed inside, which facilitates the installation of the moving gear 6 and prevents the moving gear 6 from falling off the surface of the adjusting gear 4.

[0022] A rotary motor 3 is fixedly connected to the bottom of the mounting base 1. An adjusting gear 4 is fixedly connected to the output end of the rotary motor 3. A movable rack 6 is symmetrically provided on the surface of the adjusting gear 4. The movable rack 6 is slidably connected to the fixed buckle 5. A movable rod 7 is fixedly connected to one end of the movable rack 6. Through the setting of the movable rod 7, the movable rack 6 drives the movable rod 7 to move with the guide frame 8, so that the guide frame 8 can face cartons of different widths.

[0023] A guide frame 8 is fixedly connected to one side of the movable rod 7. A mounting groove 9 is opened on one side of the guide frame 8. A guide wheel 10 is rotatably connected in the mounting groove 9. There are several guide wheels 10. Four support columns 11 are fixedly connected to the top of the mounting base 1. A top plate 12 is fixedly connected to the top of the four support columns 11. A fixing rod 13 is fixedly connected to the top of the top plate 12. Two electric telescopic blocks 14 are fixedly connected to the bottom of the fixing rod 13. The electric telescopic blocks 14 are set to extend and retract, and the height of the cleaning roller brush 18 is adjusted by the extension and retraction, so as to accommodate cartons of different heights.

[0024] Two electric telescopic blocks 14 are fixedly connected to a fixed plate 15 at the bottom of the top plate 12. Three buffer rods 16 are slidably connected to the bottom of the fixed plate 15. Mounting posts 19 are fixedly connected to the top two sides of the mounting base 1. Buffer springs 17 are sleeved on the outer arc surface of the buffer rods 16. Limiting strips 29 are fixedly installed at the top of the three buffer rods 16 through the fixed plate 15. With the setting of the buffer springs 17, when the cleaning roller brush 18 cleans the top of the carton, the buffer springs 17 can buffer the cleaning roller brush 18 when it comes into contact with the carton, preventing the cleaning roller brush 18 from flattening the carton.

[0025] Mounting posts 19 are fixedly connected to the top two sides of the mounting base 1. A sliding groove 27 is provided on one side of the mounting post 19. A motor protection block 20 is fixedly connected to one side of one of the mounting posts 19. A servo motor 21 is fixedly connected inside the motor protection block 20. The motor protection block 20 protects the servo motor 21 and prevents dust and debris from entering and causing damage to the servo motor 21.

[0026] A threaded rod 24 is rotatably mounted inside the sliding groove 27. A second bevel gear 23 is fixedly mounted on the top of the threaded rod 24. A first bevel gear 22 is meshed on the surface of the second bevel gear 23. A connecting shaft 26 is fixedly mounted between the two first bevel gears 22, and the connecting shaft 26 is rotatably connected to the top of the mounting column 19. Through the setting of the connecting shaft 26 and the first bevel gear 22, when the output end of the servo motor 21 drives the first bevel gear 22 to rotate, the first bevel gear 22 can drive the connecting shaft 26 to rotate, and then the connecting shaft 26 drives the other first bevel gear 22 to rotate, so that the two first bevel gears 22 can rotate simultaneously.

[0027] The output end of the servo motor 21 is fixedly connected to one side of a first bevel gear 22. The surface of the threaded rod 24 is provided with a movable seat 28. A spray strip 25 is fixedly installed between the two movable seats 28. Through the setting of the sliding groove 27, the threaded rod 24 and the first bevel gear 22 can be installed inside, so that the first bevel gear 22 can drive the second bevel gear 23 and the threaded rod 24 to rotate in the sliding groove 27.

[0028] The working principle of this utility model is as follows: First, the cardboard box to be sprayed is placed on the conveyor belt mechanism 2. The conveyor belt mechanism 2 is then started, moving the cardboard box. When the cardboard box contacts the front end of the guide frame 8, the rotary motor 3 is started, driving the adjusting gear 4 to rotate. As the adjusting gear 4 rotates, it drives the up-and-down moving rack 6 to move, which in turn drives the moving rod 7 to move. At this time, the guide frame 8 and guide wheel 10 can be moved closer to the carton by the moving rod 7 until both guide wheels 10 are in contact with the carton. At this time, the carton can be positioned and adjusted by the guide wheels 10 so that the carton can be adjusted to the middle position of the conveyor belt mechanism 2. At the same time, the electric telescopic block 14 on the top of the top plate 12 is activated. The two electric telescopic blocks 14 drive the cleaning roller brush 18 at the bottom to descend until the cleaning roller brush 18 contacts the top of the carton. The top of the carton can then be cleaned by the cleaning roller brush 18.

[0029] At this point, the spray bar 25 can be sprayed. Before spraying, if the height of the spray bar 25 needs to be adjusted, the servo motor 21 can drive the first bevel gear 22 to rotate. The rotation of the first bevel gear 22 then drives the connecting shaft 26 to rotate. The connecting shaft 26 then drives the other first bevel gear 22 to rotate, so that both first bevel gears 22 rotate simultaneously. When the first bevel gear 22 rotates, it drives the second bevel gear 23 to rotate. The second bevel gear 23 then drives the threaded rod 24 to rotate, and the threaded rod 24 then drives the spray bar 25 to adjust its height.
