Description

Technical Field

[0001] The invention relates to the field of corrugated paperboard, and in particular to a corrugated paper production process and production equipment. Background Art

[0002] Corrugated cardboard has a certain hardness and is elastic, with good cushioning effect; therefore, it is widely used in the field of article packaging and is in great demand; before leaving the factory, it will be made into pads or containers of various shapes and sizes according to needs, which is simpler and faster than plastic cushioning materials; after the corrugated cardboard is made, it needs to be pressed and cut using a flat creasing and cutting machine, and the grooves are cut out for easy assembly into a box shape.

[0003] At present, the existing flat-pressing, creasing and cutting machines require manual placement of corrugated cardboard. The corrugated cardboard is first placed on a pressing plate, which is then rotated against the cutting die of the flat-pressing, creasing and cutting machine to complete the pressing. It is then taken out manually, which is labor-intensive and requires high concentration, otherwise it is easy to cause safety accidents. Summary of the invention

[0004] In order to overcome the shortcomings of the prior art, one of the purposes of the present invention is to provide a corrugated paper production equipment to solve the problem that the existing flat creasing and cutting machines require manual placement and removal of corrugated paperboard, which is labor-intensive and requires high concentration, otherwise it is easy to cause safety accidents.

[0005] To achieve the above-mentioned purpose, the present invention provides a corrugated paper production equipment, including a pressing plate, and also including a paper feeding mechanism arranged above the side of the pressing plate, which is used to flatten the corrugated paperboard stack during transportation and then output it individually; a positioning component is provided in the pressing plate, which is used to position the corrugated paperboard and can be retracted into the pressing plate when the pressing plate moves to the cutting die.

[0006] Explanation: The flat creasing and cutting machine includes a creasing machine body and a pressing plate. A detachable cutting die is provided on the creasing machine body, and driving structures are provided on both sides. The cutting die corresponds to the pressing plate and is used to press corrugated cardboard. The driving structure is used to drive the pressing plate to reciprocate, so that it can continuously switch between the two states of resisting the cutting die and leaving the cutting die. The above structure is relatively existing.

[0007] The principle of the technical solution is as follows: the paper feeding mechanism is connected to the front-end process, and is used to transport the corrugated cardboard stack, flatten it during transportation, and then output it individually. The output end is located above the pressing plate where it leaves the cutting die. The output single corrugated cardboard falls on the pressing plate under the action of gravity. When falling, the pressing plate is in a state away from the cutting die, in an inclined state, and the inclination angle is small, so that the corrugated cardboard can slide to the positioning component below; the positioning component positions the corrugated cardboard, and can be retracted into the pressing plate when the pressing plate moves to the cutting die to avoid interference with pressing. At the same time, after the pressing is completed, it can be extended with a delay to allow the pressed corrugated cardboard to fall from the pressing plate, which is convenient for receiving the next corrugated cardboard, thereby realizing assembly line operation.

[0008] Beneficial effects: It can automatically place a single corrugated cardboard on the pressing plate, replacing manual work, reducing labor intensity and labor costs. At the same time, it can position the inserted corrugated cardboard to make its pressing position accurate. During pressing, the positioning component can retract, allowing the corrugated cardboard to fall naturally after pressing, achieving the effect of taking out.

[0009] As a preferred embodiment of the present invention, the paper feeding mechanism includes a first conveyor belt arranged above the pressure plate side, mounting frames are fixed on both sides of the first conveyor belt, and a plurality of limiting rollers are arranged on the mounting frames. The distance between the plurality of limiting rollers and the first conveyor belt gradually decreases, and the shortest distance is the thickness of a single corrugated cardboard. The limiting roller with the shortest distance is located on the side close to the pressure plate.

[0010] Principle of the technical solution: the first conveyor belt of the paper feeding mechanism is connected to the front-end process and is used to receive and transport the corrugated cardboard stack. The mounting frame is used to install multiple limiting rollers. The distance between the multiple limiting rollers and the first conveyor belt gradually decreases, and the shortest distance is the thickness of a single corrugated cardboard. The limiting roller with the shortest distance is located on the side close to the pressing plate. The limiting roller will flatten the corrugated cardboard stack and output a single corrugated cardboard.

[0011] As a preferred embodiment of the present invention, the positioning assembly includes an elastic limiter arranged at the lower end of the pressing plate, and the elastic limiter is used to receive the corrugated cardboard. When the pressing plate is pressed against the creasing machine body to complete the pressing, the elastic limiter can retract and release the corrugated cardboard; an annular conveying mechanism is also arranged on the pressing plate, and the annular conveying mechanism is buried in the pressing plate; a positioning plate is arranged on the annular conveying mechanism, and a positioning strip is arranged on the side of the pressing plate.

[0012] Principle of the technical solution: the elastic limiter is used to support the corrugated cardboard, and the corrugated cardboard slides on the inclined pressing plate. When it slides to the elastic limiter, the upper and lower positions are positioned. The annular conveying mechanism is buried in the pressing plate, and its annular surface is perpendicular to the placement surface of the pressing plate on which the corrugated cardboard is placed. The positioning plate is arranged on the side of the annular conveying mechanism. During operation, the positioning plate can move cyclically. When the positioning plate moves to the outside of the pressing plate, the corrugated cardboard can be pushed to press against the positioning strip, and its left and right positions are positioned to correspond to the cutting die. At the same time, after completing the positioning of the corrugated cardboard, the positioning plate can move to the inside of the pressing plate to avoid interference with pressing.

[0013] As a preferred embodiment of the present invention, the annular conveying mechanism includes a driving motor fixed in the pressure plate, a driving sprocket is fixed on the output shaft of the driving motor, a driven sprocket is also rotatably arranged in the pressure plate, chains are meshed on the outer sides of the driving sprocket and the driven sprocket, and the chain is fixedly connected to the positioning plate.

[0014] The principle of the technical solution is as follows: the driving motor is used to drive the active sprocket to rotate, and with the cooperation of the driven sprocket, drives the chain to rotate, and then drives the positioning plate to perform circular motion.

[0015] As a preferred embodiment of the present invention, the positioning plate includes a positioning seat fixed on the chain, a positioning block is rotatably connected to the positioning seat, and a torsion spring is provided between the positioning seat and the positioning block.

[0016] The principle of the technical solution is as follows: the positioning seat is used to install the positioning block and the torsion spring. The torsion spring has a small torsion force and is used to rotate the positioning block. When the corrugated cardboard is against the positioning bar, the positioning block is subjected to increased resistance, thereby compressing the torsion spring to rotate downward, and then follows the chain to move to the inside of the pressure plate.

[0017] As a preferred embodiment of the present invention, the elastic limiting member includes an electric push rod fixed in the pressure plate and a limiting plate fixed on the piston rod of the electric push rod.

[0018] The principle of the technical solution is as follows: the electric push rod is used to push out the limit plate, and the limit plate is used to support the corrugated cardboard and limit its upper and lower positions. When the pressing plate changes from a state away from the die cutting to a state against the die cutting, the electric push rod slowly retracts. When it is completely against the die cutting to complete the pressing, the electric push rod drives the limit plate to retract into the pressing plate. When the pressing plate changes from a state against the die cutting to a state away from the die cutting, the electric push rod is set to extend with a delay to allow the corrugated cardboard time to fall. When the pressing plate moves to the farthest distance from the die cutting, the electric push rod is fully extended to allow the limit plate to receive the next corrugated cardboard.

[0019] As a preferred embodiment of the present invention, the elastic limiter comprises a hydraulic damper fixed in the pressure plate, a limit block is fixed on the piston rod of the hydraulic damper, and a spring is arranged on the outer side of the hydraulic damper.

[0020] Principle of the technical solution: The above structure is another option for the elastic limiter. When the pressure plate changes from a state away from the cutting die to a state against the cutting die, the limit block is pushed back by the cutting die, and the spring is compressed at this time. When the pressure plate changes from a state against the cutting die to a state away from the cutting die, the spring rebounds, but slowly rebounds under the action of the hydraulic damper to achieve a delay effect.

[0021] As a preferred embodiment of the present invention, a second conveyor belt is arranged below the pressing plate, and a receiving slide is fixed on the creasing machine body, and the receiving slide is used to guide the pressed corrugated cardboard onto the second conveyor belt.

[0022] Principle of the technical solution: the second conveyor belt is used to transport the fallen corrugated cardboard to the next process, and the receiving slide plate is used to guide and change the inclination angle of the corrugated cardboard so that it falls parallel to the second conveyor belt.

[0023] The second object of the present invention is to provide a corrugated cardboard production process, which is applied to the corrugated paper production equipment, including: a paper feeding mechanism takes over the upper process and transports the corrugated cardboard stack; the paper feeding mechanism tilts the corrugated cardboard stack when transporting it, and outputs the corrugated cardboard in single pieces through multiple limiting rollers; the output single corrugated cardboard falls on a pressing plate and is positioned by a positioning component; after positioning is completed, the creasing machine body is started, and the pressing plate is allowed to run onto the cutting die of the creasing machine body to complete the pressing of the corrugated cardboard.
