Technical Field

[0001] The utility model relates to the field of paperboard production, in particular to a continuous paperboard collecting device. Background Art

[0002] Cardboard is a widely used packaging material made of thick paper or pulp with a certain thickness. It is usually used to make various packaging boxes, display racks, partitions, etc.

[0003] Compared with paper, the stacking height of cardboard increases too quickly due to its own thickness. Therefore, in the prior art, cardboard is usually received manually and stacked neatly before being sent out, which leads to low efficiency and high labor costs. Alternatively, cardboard is received by a paper receiving lifting platform, but due to the thickness of the cardboard itself, when the paper receiving lifting platform cleans the cardboard pile, in order to prevent the cardboard stacking height from exceeding the height of the cardboard delivery end, the output cardboard collides with the stacked cardboard, resulting in cardboard collection failure and reduced yield rate, the machine needs to be stopped to clean the cardboard pile on the paper receiving lifting platform, and the production efficiency is still not effectively improved. Summary of the invention

[0004] The utility model aims at the shortcomings of the prior art and provides a continuous paperboard collecting device which can ensure the normal collection of paperboards, ensure the yield rate and effectively improve the efficiency.

[0034] See attached Figure 2A continuous paperboard receiving device includes a frame 1, a paper receiving lifting platform 2, a temporary lifting platform 3 and a paper pushing mechanism 4. The frame 1 has a discharging station and a pushing station, which are arranged up and down. The pushing station is arranged below the discharging station. A paperboard conveying device 6 is connected to the discharging station. The conveyor belt of the paperboard conveying device 6 delivers the paperboard to the paper receiving lifting platform 2. The paper receiving lifting platform 2 is connected to a first power source for driving it to move back and forth between the discharging station and the pushing station. The first power source can be a cylinder or a motor, etc. The first power source is connected to a lifting sprocket. The lifting sprocket has a rotating shaft. Both ends of the rotating shaft have chains. The chains have four chains, which are respectively arranged around the paper receiving lifting platform 2 to ensure that the paper receiving lifting platform 2 moves up and down stably. The first power source drives the paper receiving lifting platform 2 to descend accordingly along the increasing height of the paperboard stack. The paper receiving lifting platform is provided with first gaps distributed at intervals, see attached Figure 4 , the temporary lifting platform 3 is arranged around the paper receiving lifting platform 2, and the temporary lifting platform 3 is arranged below the cardboard conveying device 6, which shortens the length of the equipment and makes the equipment layout more reasonable. The temporary lifting platform 3 is provided with a second gap parallel to the first gap, and the temporary lifting platform 3 is connected to the second power source driving it to move forward and backward. Among them, the temporary lifting platform 3 includes a mounting frame 32, a movable plate 33 and a receiving rod 31, the second power source is arranged on the mounting frame 32, and is connected to the movable plate 33 by transmission, and a plurality of receiving rods 31 are arranged on the movable plate 33 at intervals, and the receiving rod 31 includes a mounting end and a free end, the mounting end is fixed on the movable plate 33, and the free end is in a hanging state, and the second gap is arranged between adjacent receiving rods 31, the second power source drives the receiving rod 31 to receive cardboard, and the second power source drives the receiving rod 31 to move forward to receive cardboard, and when the temporary lifting platform 3 and the paper receiving lifting platform 2 transfer the cardboard pile, the receiving rod 31 enters the first gap, and a complete transfer surface is formed between the temporary lifting platform 3 and the paper receiving lifting platform 2. See attached Figure 8 The temporary lifting platform 3 is connected to the third power source by transmission. The third power source drives the temporary lifting platform 3 to move up and down. As the height of the cardboard stacked on it increases, the temporary lifting platform 3 drops accordingly. The third power source can be connected to the installation frame 32, or the temporary lifting platform 3 also includes a lifting frame 34. The installation frame 32 is set on the lifting frame 34. The third power source is connected to the lifting frame 34 by transmission. The lifting frame 34 is responsible for lifting. The second power source on the installation frame 32 drives the moving plate 33 to move forward and backward. The three cooperate to enable the temporary lifting platform 3 to connect paper and ensure smooth stacking of cardboard. See attached Figure 5 The paper pushing mechanism 4 is arranged below the paper receiving lifting platform 2, and the paper pushing mechanism 4 includes a plurality of push rods 41 and a longitudinal driving member arranged at intervals. The plurality of push rods 41 form a paper pushing plane. The paper receiving lifting platform 2 has a paper receiving plane, and the paper pushing plane is perpendicular to the paper receiving plane. The paper receiving lifting platform 2 descends to the pushing station, and the longitudinal driving member drives the push rod 41 to pass through the first gap to push out the cardboard pile.

[0035] Working principle: the paper receiving lifting platform 2 receives the cardboard at the discharging station, and the first power source drives the paper receiving lifting platform 2 to gradually descend according to the height of the cardboard pile until the paper receiving lifting platform 2 moves to the pushing station and stops descending. The longitudinal driving member drives the pushing rod 41 into the first gap to push the cardboard out, and then the paper receiving lifting platform 2 rises.

[0036] When the paper receiving lifting platform 2 stops descending, the second power source drives the temporary lifting platform 3 to move forward to receive the cardboard, and the third power source drives the temporary lifting platform 3 to descend accordingly as the height of the cardboard stacked thereon increases, until the paper receiving lifting platform 2 rises to the corresponding position of the temporary lifting platform 3 (the first gap and the second gap are in the same plane), the paper receiving lifting platform 2 receives the cardboard pile on the temporary lifting platform 3, and then the second power source drives the temporary lifting platform 3 to return to its original position, and the paper receiving lifting platform 2 and the temporary lifting platform 3 cooperate in paper receiving in a cycle, thereby ensuring the finished product rate while ensuring that the equipment can continuously and normally perform paper receiving work, effectively improving the paper receiving efficiency.

[0037] In order to prevent the fed cardboard from flying out of the paper receiving lifting platform, a front baffle 5 is provided on the frame 1, and the front baffle 5 is arranged on the crossbeam of the frame 1. The front baffle 5 can be adjusted forward and backward and arranged on the crossbeam. There are many adjustment methods, such as a longitudinal long groove is arranged on the front baffle 5, and the screws are fixed on the crossbeam through the longitudinal long groove. The front baffle 5 can prevent the cardboard from flying out and ensure that the cardboard is neatly stacked on the paper receiving lifting platform. The front baffle 5 and the cardboard conveying device 6 are arranged on both sides of the paper receiving lifting platform relatively. The front baffle 5 and the cardboard conveying device 6 are respectively arranged on the front and rear sides of the paper receiving lifting platform, or the front baffle 5 can also be arranged on the left and right groups of the paper receiving lifting platform 2.

[0038] In order to ensure that the cardboards are stacked neatly, the front baffle 5 is provided with a patting plate 7 on both sides, and the patting plate 7 is transmission-connected to the telescopic power source. A regular area is formed between the front baffle 5 and the patting plate 7. The telescopic power source drives the patting plate 7 to flatten the left and right sides of the cardboard pile to ensure that the left and right sides of the cardboard pile are stacked neatly.

[0039] In order to ensure that the temporary lifting platform 3 moves forward and backward within a preset range, a limiting push rod 8 is provided on the installation frame 32. The limiting push rod 8 has two groups. The limiting push rod 8 faces the movable plate 33. There is a limiting area between the two groups of limiting push rods 8. The movable plate 33 moves forward and backward within the limiting area. When the movable plate 33 moves to the edge of the preset range, the limiting push rod 8 acts on the movable plate 33 to prevent it from moving beyond the preset range. The limiting push rod 8 ensures that the movable plate 33 moves stably and reliably within the preset range.

[0040] Because the receiving rod 31 is suspended on the movable plate 33, in order to prevent the receiving rod 31 from shifting during operation, a positioning block 9 is provided in front of the movable plate 33, and a positioning cavity and a fixing portion are provided on the positioning block 9.
