The implementation principle is as follows:

when the material conveying device works, a worker firstly places the lower cramp 3 on the lower die holder 2, then places a cloth 26 to be buckled on the lower cramp 3, and at the moment, the end part, far away from the vibration disc 10, of the material conveying rail 11 is located above the cloth 26. Then the staff starts vibration dish 10, carries upper cramp 13 towards horn pipe 8 department, and upper cramp 13 is in the effect of self gravity from horn pipe 8 and drops to in the conveying pipeline 6. Meanwhile, the worker starts the pushing motor 93, the pushing motor 93 drives the worm 19 to rotate, the worm wheel 18 is driven to rotate, the connecting column 15 is driven to rotate, the pushing cam 92 is driven to rotate, and the pushing rod 91 is driven to slide in the direction back to the vibrating disk 10. When the pushing rod 91 slides to the position right below the conveying pipe 7, the pushing rod 91 is contacted with the upper buckle piece 13 in the conveying pipeline 6. Then, the pushing rod 91 moves continuously, so that the upper buckle piece 13 moves towards the cloth 26, and finally the upper buckle piece 13 is pushed from the conveying pipeline 6 to the position above the cloth 26, and the upper buckle piece 13 is positioned right below the upper die holder 5. When the push rod 91 pushes out the upper cramp 13, the outer side wall of the push rod 91 blocks the filling opening, and the upper cramp 13 in the conveying pipe 7 is prevented from falling into the conveying pipeline 6.

After the first upper flap 13 is fed to the cloth 26, the pushing cam 92 is continuously rotated, and the force of the pushing cam 92 on the pushing rod 91 is eliminated. At this time, the spring 23 drives the push lever 91 to slide toward the push cam 92, so that the rolling wheel 17 at the end of the push lever 91 always interferes with the rolling groove 16. As the push cam 92 continues to rotate, so that the portion of the push cam 92 protruding is farthest from the roller wheel 17, the spring 23 is driven to move the push rod 91 to the farthest distance from the upper die base 5. At this time, the filling opening is released, the upper cramp 13 in the conveying pipe 7 is conveyed towards the conveying pipeline 6 continuously, then the pushing cam 92 is pushed to rotate continuously, the protruding part of the pushing cam 92 rotates towards the pushing rod 91 again, and the upper cramp 13 in the conveying pipe 7 is conveyed towards the whole lower part of the upper die holder 5 continuously. Since the thickness of the upper cramp 13 is close to the inner height of the material conveying pipe 6, it is possible to prevent only one upper cramp 13 from being pushed by the push rod 91 at a time.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection.
