Description

Technical Field

[0001] The utility model relates to the technical field of paper feeding equipment, in particular to a paper feeding platform of a corrugator stacking machine. Background Art

[0002] A corrugated cardboard line refers to a production line for producing corrugated cardboard. When the corrugated cardboard line produces corrugated cardboard, it needs to cut the corrugated cardboard. The cut cardboard is transported to the stacker position through a paper feeder, and the cut cardboard is stacked by the stacker.

[0003] After searching, it was found that the prior art has made many improvements to the paper feeding platform of the corrugator stacking machine. For example, the patent with patent publication number CN211437134U discloses a paper feeding platform of the corrugator stacking machine, including a box body, a paper scrap cleaning mechanism and a negative pressure dust extraction mechanism; a plurality of conveying rollers driven by a power drive mechanism are arranged side by side in the box body, and the rotating shafts of the conveying rollers are rotatably mounted on the front and rear end side walls of the box body; outlets for cardboard to pass through are opened on the left and right side walls of the box body, and a slag cleaning port is provided at the bottom end of the box body; a paper scrap cleaning mechanism is provided above the conveying roller in the inner cavity of the box body; the negative pressure dust extraction mechanism includes a plurality of exhaust branch pipes, an exhaust main pipe, a filter box and an exhaust fan; a plurality of exhaust ports are opened at the top of the box body, and a plurality of the exhaust branch pipes are installed in the exhaust ports one by one and are commonly connected to the exhaust main pipe; the starting end of the exhaust main pipe is connected to the filter box, and the exhaust fan is connected to the filter box. The paper feeding platform can effectively clean up paper scraps during the cardboard transportation process, and the cleaning process is more environmentally friendly and can effectively reduce the harm to operators.

[0004] The above patents have obvious beneficial effects, but still have the following deficiencies in actual operation:

[0005] In the above-mentioned comparative document, the cardboard conveyed on the conveyor table is cleaned by a paper scrap cleaning mechanism. However, in actual operation, after the corrugated line produces the corrugated cardboard, the cardboard needs to be cut to the required size by a cutting device, and conveyed to the stacking machine position through the conveyor table, and the cut cardboard is stacked. The cardboard needs to be aligned and straightened when stacking. In the existing situation, the width of the cardboard after cutting is different. For example, when a wider conveyor table conveys a narrower cardboard, the cardboard may be offset on the conveyor table. When the offset cardboard is conveyed to the stacking machine position, it will cause the stacked cardboard to offset, affecting the neatness of the cardboard stacking. If the cardboard offset is more serious, it may also cause the cardboard on the conveyor table to be blocked or the cardboard to be damaged. Therefore, there is an urgent need in this field to improve the paper feed table of the corrugated line stacker to solve the defects of the existing technology. Utility Model Content

A first fixed plate 3 and a second fixed plate 4 are fixedly installed on the upper ends of the two support plates 2, and a first driving motor 5 is fixedly installed on one side of the first fixed plate 3. Two symmetrical rotating shafts 6 that pass through the second fixed plate 4 are rotatably connected to the first fixed plate 3. One end of a rotating shaft 6 is fixedly connected to the output end of the first driving motor 5. Several sliding sleeves 7 are slidably connected to the side surfaces of the two rotating shafts 6. An adjustment unit is provided between each sliding sleeve 7 and the rotating shaft 6. A transmission belt 8 for conveying cardboard is sleeved between the sides of each two corresponding sliding sleeves 7. A driving unit 9 for driving the two support plates 2 to move toward or away from each other is provided on one side of the bearing base plate 1.

[0032] Specific implementation method in this embodiment: In this embodiment, when the cut cardboard needs to be transported, the distance between the first fixed plate 3 and the second fixed plate 4 can be adjusted according to the width of the cardboard. The two support plates 2 can be driven to move toward or away from each other by the driving unit 9. When the two support plates 2 drive the first fixed plate 3 and the second fixed plate 4 to move, the second fixed plate 4 slides along the side of the rotating shaft 6. After the distance between the first fixed plate 3 and the second fixed plate 4 is adjusted, the position of the plurality of sliding sleeves 7 on the side of the rotating shaft 6 is adjusted by the adjusting unit. The sides of the transmission belts 8 on both sides are respectively aligned with the first fixed plate 3 and The side surfaces of the second fixed plates 4 are abutted against each other, and the cut cardboard is placed on several transmission belts 8. The first drive motor 5 is started, and the output end of the first drive motor 5 drives the rotating shaft 6 to rotate, and the rotating shaft 6 drives the sliding sleeve 7 to rotate, and the sliding sleeve 7 drives the transmission belt 8 to rotate the cardboard. When the cardboard is transported, the first fixed plate 3 and the second fixed plate 4 play a positioning role on the cardboard to prevent the cardboard from shifting. The distance between the first fixed plate 3 and the second fixed plate 4 can be adjusted according to the width of the cardboard to be transported, thereby improving the stability of the cardboard when being transported on the paper feeding platform and preventing the cardboard from shifting when being transported on the conveying platform.
