The connecting block 13, the through hole 14, the insertion hole 15, the blocking plate 19, the connecting piece 16, the feeding pipe 10 and the sealing plug 11 in the blocking assembly 12 cooperate with each other to effectively block and selectively open the feeding hole 22. When the piston plate 7 moves downward, the blocking plate 19 can timely block the feeding pipe 10, effectively prevent the adhesive remaining in the feeding pipe 10 from flowing to the top of the piston plate 7, avoid the problem that the piston plate 7 is blocked due to the adhesion of the adhesive, and reduce the cumbersome operation of cleaning and assembling the box body 5. When the adhesive needs to be added, the feeding pipe 10 is automatically opened by the magnetic linkage between the piston plate 7 and the blocking plate 19, without the need of an additional complex control mechanism, so that the structure is simple and reliable, and the automation degree and working efficiency of the equipment are improved.

[0031] As shown in Figure 3 , in the embodiment, the surface of the piston plate 7 is inlaid with a lower magnetic block 21, and an upper magnetic block 20 is fixed to the connecting piece 16. The upper magnetic block 20 is located above the lower magnetic block 21, and the upper and lower magnetic poles of the upper magnetic block 20 and the lower magnetic block 21 are opposite.

Start the driving cylinder 6, the output end of the driving cylinder 6 pushes the piston plate 7 to move downward in the box 5, the adhesive is pressure fed to the nozzle 4 through the connecting hose, the nozzle 4 is moved on the support 2 by the moving cylinder 3, and the corrugated carton is sprayed with the adhesive. When it is needed to fill the adhesive into the box 5, the sealing plug 11 at the end of the feeding pipe 10 is opened, and the adhesive is injected into the feeding pipe 10. With the upward movement of the piston plate 7, the lower magnetic block 21 approaches the upper magnetic block 20, and the connecting piece 16 is moved upward through the magnetic force, so that the blocking plate 19 is pulled out of the through hole 14, and the adhesive can smoothly enter the box 5 through the feeding hole 22. When the filling is completed, the piston plate 7 moves downward, the distance between the upper magnetic block 20 and the lower magnetic block 21 increases, the magnetic force is weakened, the blocking plate 19 is inserted into the through hole 14 under the action of gravity, the feeding hole 22 is blocked, and the residual adhesive in the feeding pipe 10 is prevented from flowing to the top of the piston plate 7.
