[0024] Embodiment 1

[0025] As Figures 1-3 shown, a bonding device for multi-layer corrugated paper proposed by the present utility model includes a bonding table 1, a glue application assembly, and a swinging mechanism. An L-shaped frame 2 is provided on the bonding table 1. The vertical section of the L-shaped frame 2 is connected to the bonding table 1, and a glue tank 3 is provided on the horizontal section of the L-shaped frame 2. The glue application assembly is movably provided below the horizontal section of the L-shaped frame 2, and an adjusting mechanism for adjusting its glue application height is provided on one side thereof. The swinging mechanism is provided on one side of the glue application assembly and is used to drive the glue application assembly to apply glue reciprocally within a certain range.

[0026] As Figure 1 shown, the glue application assembly includes a C-shaped frame 4, a glue application tube 5, and a pump body 6. The glue application tube 5 is horizontally rotatably provided therein, and a plurality of groups of glue application nozzles 7 are linearly and equidistantly provided at the bottom of the glue application tube 5. The pump body 6 is installed on the L-shaped frame 2, its liquid inlet end communicates with the glue tank 3, its output end is connected to a glue delivery tube 8, and the bottom end of the glue delivery tube 8 is connected to the glue application tube 5.

[0027] When glue application is required, the glue liquid in the glue tank 3 is transported to the glue application tube 5 through the pump body 6 via the glue delivery tube 8, and finally sprayed out through the glue application nozzles 7 to apply glue to the corrugated paper.

[0028] As Figure 2 shown, the adjusting mechanism includes a motor 9, a screw 10, a guide post 11, and a moving plate 12. The motor 9 is installed on the top of the L-shaped frame 2, its output end passes through the L-shaped frame 2 and is connected to a screw 10. The bottom end of the screw 10 is rotatably connected to the bonding table 1 through a bearing. The moving plate 12 is threadedly connected to the screw 10. The guide post 11 is vertically provided inside the L-shaped frame 2, its top end is connected to the L-shaped frame 2, its bottom end is connected to the bonding table 1, and the moving plate 12 is slidably connected to the guide post 11. The C-shaped frame 4 is installed on the side of the moving plate 12.

[0029] As shown Figure 1 in FIG. 1, a corrugated telescopic section is provided in the middle of the glue delivery pipe 8, which is used to adaptively expand and contract with the change of the position of the glue application pipe 5.

[0030] When applying glue to corrugated paper with different thicknesses or different layers, it is necessary to change the glue application height of the glue application nozzle 7. At this time, the motor 9 drives the screw 10 to rotate. During the rotation of the screw 10, the moving plate 12 is driven to move vertically under the limitation of the guide post 11. During the moving process, the height of the glue application pipe 5 and the glue application pipe 5 is adjusted through the C-shaped frame 4. During the height adjustment process, the glue delivery pipe 8 adaptively expands and contracts under the action of the corrugated telescopic section.

[0034] During the glue application process, the motor 13 drives the turntable 14 to rotate. During the rotation of the turntable 14, the convex shaft 15 is driven to make a circular motion. During the motion process, it squeezes the hole wall of the strip hole 18, and then the strip plate 17 drives the glue application pipe 5 to swing left and right within a certain range through the connecting shaft 16, thereby expanding its glue application range and improving the uniformity of glue application.

[0035] As shown Figure 3 in FIG. 4, a groove 19 is provided on the side of the turntable 14. A plurality of threaded holes 20 are linearly and equidistantly provided in the groove 19. One end of the convex shaft 15 is connected with a threaded post 21, and the threaded post 21 is threadedly connected with the corresponding threaded hole 20. A handle 22 for assisting in applying force during rotation is provided on the outer side of the other end of the convex shaft 15.

[0036] By providing a plurality of threaded holes 20, the convex shaft 15 can be unscrewed through the handle 22, so that the convex shaft 15 is threadedly connected with the threaded holes 20 at different positions through the threaded post 21, thereby changing its distance from the center of the turntable 14 and adjusting the range of its circular motion. Furthermore, the swing amplitude of the glue application pipe 5 can be adjusted according to the glue application area of the corrugated paper, improving the overall adjustability.

[0037] The embodiments of the present utility model have been described in detail in conjunction with the accompanying drawings.
