[0021] A hydraulic telescopic frame 31 is movably installed inside the side plate 3, two push plates 32 are movably installed on one side of the hydraulic telescopic frame 31, a first guide rod 34 is fixedly installed between the side plates 3, the push plate 32 is movably installed on the surface of the first guide rod 34, a paper support 33 is fixedly installed inside the side plate 3, and the push plate 32 is movably sleeved on the surface of the paper support 33.

[0022] In this embodiment, the cardboard body 100 enters the interior of the buffer box 2 from the paper feed port 21, and after descending due to gravity, it will be offset from the previous cardboard body 100 in the front, back, left, and right directions. At this time, the hydraulic telescopic frames 31 arranged on both sides are used to simultaneously push the push plates 32 to move, and the push plates 32 stop when they encounter a certain resistance. At this time, the left and right sides of all the cardboard bodies 100 will be flush; and when the cardboard body 100 is fed from the paper feeding port 5, the conveying component 7 drives the bottom cardboard body 100 to move, and the control component 6 creates an obstacle to the cardboard body 100. At this time, the control component 6 can be set to be lifted at the same interval, so as to control the front and back positions of the fed cardboard bodies 100 to be the same, thereby improving production accuracy.

[0023] There are four first guide rods 34 , two of which are arranged at a height higher than the paper inlet 21 , and the other two are arranged at a height lower than the paper support 33 .

[0024] In this embodiment, the first guide rod 34 higher than the paper feed port 21 can prevent the cardboard body 100 entering from the paper feed port 21 from being affected by the first guide rod 34. The cardboard body 100 can be supported by the provided paper support 33, and the first guide rod 34 can also be prevented from affecting the cardboard body 100.

[0025] The transmission assembly 7 includes a fixed plate 71, a mounting groove 11 is provided in the middle of the mounting base 1, the fixed plate 71 is fixedly mounted on the inner wall of the mounting groove 11, a second cylinder 72 is fixedly mounted on the bottom of the fixed plate 71, the output end of the second cylinder 72 passes through the fixed plate 71 and is fixedly sleeved with a lifting plate 73, two parallel rotating rollers 75 are rotatably mounted on the top of the lifting plate 73, both ends of the rotating rollers 75 are fixedly sleeved with paper feeding wheels 76, one end of the two rotating rollers 75 are transmission-connected by a first synchronous belt 77, a motor 78 is fixedly mounted on the bottom of the lifting plate 73, the output end of the motor 78 is transmission-connected to one end of one of the rotating rollers 75 through a second synchronous belt 79, a second guide rod 74 is fixedly mounted on the bottom of the lifting plate 73, and the second guide rod 74 is movably mounted on the top of the fixed plate 71.

[0026] In this embodiment, the motor 78 is driven by the second synchronous belt 79 and then by the first synchronous belt 77 to simultaneously drive the four paper feeding wheels 76 to rotate. After controlling the output end of the second cylinder 72 to move upward, the lifting plate 73 can be driven to push the paper feeding wheels 76 upward, so that the paper feeding wheels 76 contact the bottom surface of the paperboard body 100, thereby pushing the bottom paperboard body 100 toward the paper feeding port 5.

[0027] Air exhaust grooves 22 are provided on both the front and rear sides of the buffer box 2 , and a sponge protective layer is bonded to the inner wall of the buffer box 2 away from the paper inlet 21 .

[0028] In this embodiment, the exhaust groove 22 provided can effectively discharge the air when the cardboard body 100 descends, enabling the cardboard body 100 to descend faster and with less offset. Additionally, since the cardboard body 100 has a certain speed when entering the buffer box 2, the added sponge protection layer can reduce the degree of deformation of the cardboard body 100 during impact.

[0029] The control component 6 includes a mounting frame 61 which is fixedly installed on the side of the buffer box 2. A first cylinder 62 is fixedly installed on the side of the mounting frame 61. A connecting block 63 is fixedly sleeved on the output end of the first cylinder 62. A baffle 64 is fixedly installed on the side of the connecting block 63, and the side of the baffle 64 is in contact with the side of the buffer box 2.

[0030] In this embodiment, the first cylinder 62 can control the lifting of the baffle 64 through the connecting block 63, thereby controlling the paper output of the cardboard body 100. Additionally, by controlling the lifting distance, papers of different thicknesses can be controlled.

[0031] Working principle: The cardboard body 100 enters the interior of the buffer box 2 from the paper inlet 21. After descending under the action of gravity, it will generate an offset in the front, back, left, and right directions from the previous cardboard body 100. At this time, the hydraulic telescopic frames 31 provided on both sides are used to simultaneously push the push plate 32 to move, and stop when the push plate 32 encounters a certain resistance. At this time, the left and right sides of all the cardboard bodies 100 will be flush; when the cardboard body 100 is fed from the paper outlet 5, the conveyor component 7 drives the lowermost cardboard body 100 to move, and the control component 6 obstructs the cardboard body 100. At this time, the control component 6 can be set to lift at the same interval, so as to control the positions of the fed cardboard bodies 100 to be the same before and after, improving the production accuracy.
