Description

Technical Field

[0001] The utility model belongs to the technical field of carton drying, in particular to a carton printing and drying device. Background Art

[0002] A carton printing machine is a device that can print text, patterns or other information onto the surface of a carton. It generally uses roller printing and has the characteristics of large-scale and efficient production. It generally includes process flows such as plate mounting, inking, embossing, and paper feeding.

[0003] After cartons are printed and ejected from the printing press, the ink on the designs is often still wet and needs to be dried quickly for easy storage. Currently, the conveyor belt that transports the cartons is typically placed inside the box, where hot air is introduced for drying. This hot air blows directly onto the cartons, which can easily move the cartons on the conveyor belt and cause them to shift. The hot air then flows out through openings on both sides of the box, reducing the contact time between the hot air and the cartons. This results in low hot air utilization and energy waste.

[0014] In order to more clearly understand the technical solution of the present invention, the present invention is further described below with reference to the accompanying drawings.

[0015] like Figure 1-3The carton printing and drying device shown includes a frame 1, with an active roller 2 and a driven roller 3 horizontally and symmetrically arranged between the two ends of the frame 1. One end of the active roller 2 is connected to the transmission shaft of the motor 4. A support plate 18 is fixedly arranged horizontally on the frame 1, and the motor 4 is fixedly arranged on the support plate 18 to ensure the stability of the position of the motor 4. A conveyor belt 5 is tightly fitted on the active roller 2 and the driven roller 3. The cartons are placed stably on the conveyor belt 5. When the motor 4 is started, the cartons on the conveyor belt 5 move accordingly. A box 6 with a downward opening is arranged above the frame 1. The lower end of the box 6 is fixedly connected to the upper end wall of the frame 1 to ensure the stability and reliability of the position of the box 6. A first partition 7 is vertically fixed on the side of the box 6 close to the active roller 2 to divide the interior of the box 6 into multiple areas. The size of the first partition 7 is the same as the size inside the box 6, which ensures that the first partition 7 is in contact with the inner surface of the box 6. The inner wall of the box body 6 is tightly connected without affecting the movement of the carton on the conveyor belt 5. A second partition 8 is fixed vertically and symmetrically in the box body 6 on one side of the first partition 7, dividing the box body 6 on the first partition 7 into multiple areas. The distance between the lower end of the second partition 8 and the conveyor belt 5 is greater than the distance between the lower end of the first partition 7 and the conveyor belt 5, which is convenient for the circulation of hot air. A third partition 9 is fixed horizontally on the lower part of the second partition 8 and close to the inner wall of the box body 6 to block and disperse the hot air. The box body above the third partition 9 An air inlet pipe 10 is provided on the side wall 6, and a heater 11 is provided on the air inlet pipe 10. A plurality of first ventilation holes 12 are evenly opened on the third partition 9. When the heater 11 is started, the warm air first enters the area above the third partition 9 along the air inlet pipe 10, and then enters the area below the third partition 9 through the first ventilation holes 12, drying the cartons on the conveyor belt 5, reducing the flow rate of the hot air, and avoiding the hot air blowing directly on the cartons to cause the displacement of the carton position. A fourth partition 13 is fixedly provided horizontally between the lower parts of the second partition 8. A plurality of second ventilation holes 14 are evenly arranged on the plate 13. After the hot air dries the cartons, it flows along the second ventilation holes 14 into the top of the fourth partition 13 for reuse. A third ventilation hole 15 is provided in the middle of the upper portion of the first partition 7. The hot air on the fourth partition 13 passes through the third ventilation hole 15 and reaches the box body 6 on the other side of the first partition 7, preheating and drying the cartons on the internal conveyor belt 5. The aperture of the first ventilation hole 12 is the same as that of the second ventilation hole 14 and is smaller than that of the third ventilation hole 15, ensuring smooth circulation of the hot air. An exhaust duct 16 is provided on the upper end wall of the box body 6 facing away from the first partition 7. The air that has been preheated and dried on the cartons is discharged along the exhaust duct 16.

[0016] A plurality of fifth partitions 17 are vertically and evenly fixed in the box body 6 between the first partition 7 and the exhaust duct 16, dividing the box body 6 into multiple areas. The distance between the lower end of the fifth partition 17 and the conveyor belt 5 is greater than the distance between the lower end of the first partition 7 and the conveyor belt 5. The hot air is blocked by the fifth partition 17 and flows along the gap between the lower end of the fifth partition 17 and the conveyor belt 5, ensuring sufficient contact between the hot air and the cartons on the conveyor belt 5, and preheating and drying the cartons.

[0017] The above description is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, features and principles described in the scope of the present invention patent application are included in the scope of the present invention patent application.
