Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard production technology, specifically to a corrugated cardboard humidification device for a corrugated cardboard production line. Background Technology

[0002] Corrugated paper is a sheet-like material made by bonding linerboard and corrugated paper formed by corrugating rollers. It is generally divided into single-wall and double-wall corrugated paperboard, and further classified into five types according to the size of the corrugations: A, B, C, E, and F. Corrugated paper has been invented and used for over a century, possessing advantages such as low cost, light weight, easy processing, high strength, excellent printability, and convenient storage and handling. Over 80% of corrugated paper can be recycled. It is widely used for packaging food and digital products, is relatively environmentally friendly, and its applications are quite extensive. During the processing of corrugated paperboard, its surface needs to be moistened to facilitate subsequent processing.

[0003] In existing corrugated cardboard humidification devices, multiple sets of nozzles are used simultaneously to humidify the cardboard in order to improve the efficiency of cardboard humidification. However, there are gaps between the nozzles, which leads to uneven wetting of the corrugated cardboard surface during the humidification process. Some areas of the cardboard surface are more moist than others, which affects the subsequent processing quality of the cardboard. Furthermore, existing humidification devices do not have a function to flip the cardboard, so cardboard that has been humidified on one side needs to be reprocessed, resulting in low humidification efficiency. Summary of the Invention

The moving frame 9 is slidably connected, the rack 16 is meshed with the gear 15, the moving frame 9 is equipped with a cylinder 17, the rack 16 is connected to the output end of the piston rod of the cylinder 17, the flying disc 8 is rotatably connected to the mounting bracket 2 through a rotating shaft, the end of the first support rod 5 away from the second support rod 6 is rotatably connected to the slider 4 through a rotating shaft, the end of the second support rod 6 away from the first support rod 5 is rotatably connected to the flying disc 8 through a rotating shaft, the first support rod 5 and the second support rod 6 are slidably connected, the second support rod 6 is equipped with a threaded rod 7, the right end of the threaded rod 7 passes through the second support rod 6 and is rotatably connected to the second support rod 6 through a bearing, the left end of the threaded rod 7 passes through the first support rod 5 and is threadedly connected to the first support rod 5.

[0022] Based on the installation gap between each group of nozzles in the combined nozzle 3, the motor inside the second support rod 6 is activated to drive the threaded rod 7 to rotate. Under the limiting action of the second support rod 6, the extension lengths of the first support rod 5 and the second support rod 6 are adjusted. During the process of water mist spraying by the combined nozzle 3, the motor is activated to drive the rotation of the flying disc 8. During the rotation of the flying disc 8, the second support rod 6 and the first support rod 5 are driven to swing back and forth, thereby driving the slider 4, which is slidably connected to the mounting frame 2, and the combined nozzle 3 on the slider 4 to move back and forth, so as to achieve uniform humidification spraying of the cardboard in conjunction with the combined nozzle 3.

[0023] like Figure 3, Figure 4 and Figure 5 As shown, both ends of the two sets of lead screws 10 pass through the bracket 1 and are rotatably connected to the bracket 1. The two sets of lead screws 10 pass through the movable frame 9 and are threadedly connected to the movable frame 9. Synchronous pulleys 11 are sleeved on the left end of each set of lead screws 10. A synchronous belt 12 is provided on the bracket 1, and the synchronous belt 12 is connected to the two sets of synchronous pulleys 11 respectively. Four sets of symmetrically distributed clamping blocks 18 are provided in the mounting frame 13, and two sets of symmetrically distributed first adjusting rods 19 are provided in the mounting frame 13. The mounting frame 13 is provided with two sets of symmetrically distributed second adjusting rods 20. Both sets of first adjusting rods 19 and second adjusting rods 20 are slidably connected to the mounting frame 13. Adjacent sets of first adjusting rods 19 and second adjusting rods 20 are perpendicularly distributed. Clamping blocks 18 are slidably connected to the corresponding first adjusting rods 19 and second adjusting rods 20 respectively. The mounting frame 13 is provided with two sets of symmetrically distributed first bidirectional screws 21 and second bidirectional screws 22. Both ends of the first bidirectional screws 21 and second bidirectional screws 22 pass through the mounting frame 13 and are rotatably connected to the mounting frame 13.

[0024] The installation frame 13 and the moving frame 9 enable automatic movement of the cardboard. After humidifying one side of the cardboard with spray, the cardboard is automatically flipped, thus completing double-sided humidification with the combined nozzle 3. The motor inside the installation frame 13 drives the first bidirectional screw 21 or the second bidirectional screw 22 to rotate, adjusting the distance between the two sets of symmetrically distributed first adjusting rods 19 and the two sets of symmetrically distributed second adjusting rods 20.

After the cardboard is fixed, the motor on the bracket 1 is started to drive the lead screw 10 to rotate. Under the limiting action of the bracket 1, the moving frame 9 drives the installation frame 13 and the cardboard inside to slide on the bracket 1, allowing the cardboard to work with the combined nozzle 3 to humidify one side of the cardboard. Then, the cylinder 17 inside the moving frame 9 is started to drive the rack 16 to slide and engage with the gear 15, causing the installation shaft 14 to drive the installation frame 13 to flip on the moving frame 9, thus completing the automatic flipping of the cardboard and the double-sided humidification.

[0025] This utility model provides a corrugated cardboard humidification device for a corrugated cardboard production line. The specific working principle is as follows: Based on the installation gap between the nozzles in the combined spray head 3, the motor inside the second support rod 6 is activated to drive the threaded rod 7 to rotate. Under the limiting action of the second support rod 6, the extension lengths of the first support rod 5 and the second support rod 6 are adjusted. During the water mist spraying process of the combined spray head 3, the motor is activated to drive the rotation of the fly disc 8. The rotation of the fly disc 8 drives the second support rod 6 and the first support rod 5 to swing back and forth, thereby driving the slider 4 slidably connected to the mounting frame 2 and the combined spray head 3 on the slider 4 to move back and forth. This, in conjunction with the combined spray head 3, achieves uniform humidification spraying of the cardboard. The motor inside the mounting frame 13 drives either the first bidirectional screw 21 or the second bidirectional screw 2... The rotation of 2 adjusts the distance between the two sets of symmetrically distributed first adjusting rods 19 and the two sets of symmetrically distributed second adjusting rods 20, and then adjusts the distance between the four sets of clamping blocks 18 to fix different types of cardboard. After the cardboard is fixed, the motor on the bracket 1 is started to drive the lead screw 10 to rotate. Under the limiting action of the bracket 1, the moving frame 9 drives the mounting frame 13 and the cardboard inside to slide on the bracket 1, so that the cardboard and the combined nozzle 3 can complete the humidification of one side of the cardboard. Then, the cylinder 17 in the moving frame 9 is started to drive the rack 16 to slide and engage with the gear 15 so that the mounting shaft 14 drives the mounting frame 13 to flip on the moving frame 9, thus completing the automatic flipping of the cardboard and completing the double-sided humidification of the cardboard.
