The cardboards 5 on both sides of the middle paper stop component 2 are respectively aligned front and back under the action of the synchronous stops 38, so that the two pieces of cardboard 5 are pushed to the nailing machine 6 for nailing and fixing. After the fixing is completed, they continue to be pushed to the back process. The number and position of the transmission wheel 35 and the driven wheel 36 in the request itself can be set according to the actual situation. Multiple sets of transmission wheels 35, driven wheels 36, and synchronous belts 37 can be set, or they can be set on one side or both sides of the lower plate 32, or they can be used synchronously in combination with the conveyor belt.

The paper pushing cylinder 46 can realize the adjustment of the position of the push plate 47 along the connecting square tube 12, so that the side push plate component 4 can adapt to more models and sizes of cardboards 5.

[0027] When the paper baffle 24 enters the middle of the movable plate 3, the side push plate components 4 arranged on both sides can push the paperboard 5 so that the fixed edges in the middle of the two pieces of paperboard 5 can fit the paper baffle 24 in the middle, so that the paperboard 5 is aligned left and right, and plays a guiding and stabilizing role when the paperboard 5 moves forward and backward. In addition, under the action of the synchronous block 38 arranged on the synchronous belt 37, the front and rear squares of the paperboards 5 on both sides are aligned. The aligned paperboards 5 continue to be transported forward and transported to the nailing machine 6 for nailing and fixing.

[0028] In addition, a ground rail 7 is provided at the bottom of the frame 1, and a rack is fixedly provided on the ground rail 7.
