Description

Technical Field

[0001] The invention relates to the technical field of automatic paper feeding equipment for corrugated paper box production, in particular to an automatic paper feeding device for corrugated paper box production. Background Art

[0002] Cardboard, also known as corrugated cardboard, is made of at least one layer of corrugated paper and one layer of boxboard. It has good elasticity and extensibility and is mainly used to make cartons, cardboard cores and other packaging materials for fragile goods. It is mainly made of traditional straw pulp and waste paper through pulping to make raw cardboard similar to yellow cardboard, which is then mechanically processed and rolled into a corrugated shape, and then bonded to the boxboard with adhesives such as sodium silicate on its surface.

[0003] Existing automatic paper feeding devices often use an adsorption and grabbing method to pick up cardboard. This conveying method increases the structural complexity of the device and reduces the reliability of the device. There is no supporting device on the inner wall of the conveyor belt, so when the cardboard reaches a certain weight during transportation on the conveyor belt, the conveyor belt will sink, resulting in the need to manually reduce the number of cardboards, resulting in the inability to achieve fully automated transportation, which increases labor waste and reduces work efficiency due to unstable transportation. The size of the cardboard box cannot be controlled, and the cardboard cannot be fixed to make it disordered and cannot be kept neat at all times, which will affect the continuous movement of the push plate. The existing automatic paper feeding device is not convenient for cleaning paper scraps, which will cause the machine to jam for a long time and affect normal operation. Summary of the invention

On the contrary, when the threaded rod rotates counterclockwise, it will drive the partition and the telescopic rod to move backward, and at the same time, the telescopic rod will drive the pushing plate, the shrinking rod and the paper feeding paper to move backward. When the pushing plate and the paper feeding paper move forward and backward, the bottom passes through the sliding rod, and the sliding rod makes it more convenient and sensitive to move, reduces the friction between the bottom of the pushing plate and the paper feeding paper and the main body of the paper feeding device, so that it can achieve a longer service life, avoids unnecessary losses and waste, and adopts a multi-stage pushing plate to further improve work efficiency.

[0017] The electric push rod of the present invention can drive the square plate to move left and right when running, so that the shell can more conveniently fix corrugated paper shells of different sizes, reduce manual operation, and fix the corrugated paper boxes faster, and put into work to effectively improve the work efficiency. The push-pull rod inside the shell can also move left and right with the electric push rod, effectively controlling the stability of the shell. When the shell moves left and right, the support rod and the pull rod can be driven by the push rod to move left and right together, so that the shell can be avoided from tilting to both sides when operating large corrugated paper, so that unnecessary waste and the waste of materials, machines, labor and time caused by the push plate can be avoided. When the push plate moves back and forth, the push rod can move back and forth, and the push rod can move back and forth, and the lifting plate can move up and down when the push plate moves back and forth, and the lifting plate can drive the corrugated paper board to move up and down, so that the feeding paper board can be avoided when working. The fast speed causes the feeding paper board to drive the paper board back together. When the feeding paper board passes the paper feeding port, the soft tooth chain will tilt outward due to pressure, but when the feeding paper board returns, the soft tooth chain will push the corrugated paper box onto the conveyor belt due to pressure, effectively avoiding the instability problem of pushing corrugated paper, so as to improve the paper feeding efficiency.

[0018] When the second motor of the present invention is turned on, the output end will drive the pulley to rotate clockwise, and the pulley drives the rotating rod to rotate in the same direction. The rotating rod drives the conveyor belt to run through friction. The paper feeding load-bearing plate is higher than the conveyor belt, which will make the corrugated paper reach the conveyor belt along the paper feeding load-bearing plate, thus avoiding the cardboard from falling onto the conveyor belt, thereby improving work efficiency and reducing unnecessary manual operation. The load-bearing thin plate on the inner wall of the conveyor belt enables the conveyor belt to bear the weight of the cardboard better, so as to avoid the problem of the conveyor belt sinking when the corrugated cardboard is piled up or the workload is large, so that it achieves a more stable effect and effectively improves work efficiency. When the corrugated cardboard box passes through the conveyor belt, the soft board will adjust the position of the cardboard box to avoid the work stopping caused by the deviation of the cardboard box, avoid the waste of time and improve work efficiency. When the soft board contacts the cardboard, it will touch the extrusion spring. After the cardboard passes, the elastic force of the spring will quickly make the soft board return to the original position and repeat the next operation, thereby achieving the stability of operation, improving work efficiency, reducing manual operation and completing the carton transportation work more effectively. The electric push-pull rod pushes the paper scrap cleaning plate to move back and forth during movement, and the paper scrap cleaning plate drives the paper scraps to move toward the paper scrap cleaning slot, effectively cleaning the paper scraps and garbage inside the machine and increasing the service life of the machine.

When the paperboard 45 passes through the paper feeding port 65, the soft tooth chain 63 will tilt outward due to pressure, but when the paperboard 45 returns, the soft tooth chain 63 will push the corrugated paper box onto the conveyor belt 10 due to pressure, which effectively avoids the instability problem of pushing corrugated paper and improves the paper feeding efficiency.When the second motor 2 is turned on, the output end will drive the pulley 76 to rotate clockwise, and the pulley 76 drives the rotating rod 77 to rotate in the same direction. The rotating rod 77 drives the conveyor belt 10 to run through friction. The paper feeding load-bearing plate 74 is higher than the conveyor belt 10, which will allow the corrugated paper to reach the conveyor belt 10 along the paper feeding load-bearing plate 74. This prevents the cardboard from falling onto the conveyor belt 10, thereby improving work efficiency and reducing unnecessary manual operations. The load-bearing thin plate 79 on the inner wall of the conveyor belt 10 better enables the conveyor belt 10 to bear the weight of the cardboard, so as to avoid the accumulation of corrugated cardboard or the occurrence of heavy workload. The problem of the conveyor belt 10 sinking is solved, making it more stable and effectively improving work efficiency. When the corrugated box passes through the conveyor belt 10, the soft board 704 will adjust the position of the box to avoid the work stopping caused by the deviation of the box, avoiding the waste of time and improving work efficiency. The soft board 704 will touch the extrusion spring 72 when it contacts the cardboard.
