Description

Technical Field

[0001] The present invention relates to the technical field of boxboard paper reeling, and more specifically to a flexible paper reeling system and method for a boxboard paper machine. Background Art

[0002] Container board, also known as kraft paper and cow cardboard, is one of the main types of paper for cartons. It is mainly made into corrugated boxes after being bonded with corrugated paper cores. It is used to package household appliances, daily necessities, needle-cotton fabrics, cultural supplies, and outer packaging of Chinese and Western medicines. During production, it is generally rolled and stored through a flexible paper rolling system. The flexible paper rolling system generally contains a roll support device, a tension control system, a correction device, a guide roller, a tension detection system, a winding shaft, a pressure control device and a tension control system for automatic regulation and winding to ensure the quality of the container board after winding. The existing winding methods are divided into two types: winding with a shaft core and winding without a shaft core.

[0003] When the existing shaft core reel is reeled up, the shaft core is generally installed on the reel by plugging or snapping, and then one end of the corrugated board paper is fixed to the shaft core by glue or tape, and then fixed by a full-automatic strapping machine when the reeling is completed. However, fixing the corrugated board paper to the shaft core by glue or tape can easily lead to the pasted part being unusable, thereby causing waste. At the same time, fixing by glue requires waiting for a period of time or using cooling equipment to cool and fix it before reeling can be carried out, which can easily affect the processing progress, increase power loss, and is inconvenient to use.

[0014] A method for a flexible paper reel system for a boxboard machine, comprising the following steps: S1. First, the roll core is placed on the first conveyor belt by an external robot arm and clamped on the arc-shaped limit plate. Then, the first conveyor belt is started to transport the roll core. When the roll core is aligned with the cylinder, the push motor is started. The output of the push motor causes the first push plate and the second push plate to move, thereby causing the roll core to be sleeved on the cylinder. S2, then start the output motor, the output of the output motor will make the cylinder move in a circular motion, so that the winding core corresponds to the fixed plate, and then the fixed plate is inserted into the fixed hole on the winding core through the multi-stage electric push rod, and the fixed roller fixes the boxboard paper at this time; S3. When the boxboard paper contacts the suction cup, the drive motor is started. The output of the drive motor will first make the suction cup absorb and fix the boxboard paper, and at the same time the multi-stage electric push rod will shrink. Then the drive motor will drive the cylinder to rotate, and then the reel core will reel the boxboard paper. S4. When the reel is finished, the cardboard is first fixed by the fixing roller, and then cut by the cutting knife. When the cutting is completed, it is bundled by the fully automatic strapping machine, so there is no need for glue to fix it, reducing waste; S5. When the bundling is completed, the output motor outputs so that the wound core is at the bottom, and then the push motor is started. The push motor output pushes the wound core and the unwound core through the first push plate and the second push plate, so that the wound core is transported through the second conveyor belt, so that the core is automatically replaced to reduce manpower.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the multi-stage electric push rod and the fixed plate, one end of the corrugated board paper can be pushed and contacted with the suction cup, and then the driving motor is used to rotate the rotating column. The rotation of the rotating column will move the moving block through the pulling plate and the annular plate. The movement of the moving block will first move the piston. The movement of the piston will cause the suction cup to adsorb the corrugated board paper and then fix it. Then the moving block continues to move and connects to the rotating column through the arc block. At this time, the rotation of the rotating column will cause the roll core to rotate through the cylinder, and then the corrugated board paper is rolled up. After the rolling is completed and cut, it is bundled from the outside through the fully automatic strapping machine to fix the corrugated board paper, avoiding waste caused by fixing it on the roll core by glue. At the same time, the first conveyor belt, the second conveyor belt, the arc limit plate, the first push plate and the second push plate can automatically position and replace the rolled and unrolled roll cores to reduce manpower.

[0016] 2. The trapezoidal extrusion block can reset the annular plate and the moving block when the core is rolled up and moves in a circular motion. The reset of the moving block will cause the L-shaped clamping plate to engage with the annular gear block to limit the position of the cylinder, thereby preventing the rotation from deviating from the initial position and affecting subsequent use.

[0017] 3. Through the setting of the lifting rod, horizontal block, L-shaped support plate, second spring and fixed roller, the boxboard paper can be limited when it is pushed, so as to avoid one end of the boxboard paper from tilting up and affecting the subsequent adsorption and fixation. Through the setting of the round block, the four cylinders can be installed and rotated, so that when winding, the wound core and the unwound core can be replaced, avoiding separate replacement time and affecting the processing progress.

[0052] The working principle and use process of the present invention are as follows: when in use, the winding core 9 is first placed on the first conveyor belt 7 by an external robot or manually, and is clamped on the arc-shaped limit plate, and then the first conveyor belt 7 is started to transport the winding core 9. When the winding core 9 is aligned with the cylinder 10, the pushing motor 2 is started, and the output of the pushing motor 2 causes the first screw rod 41 to rotate, and the rotation of the first screw rod 41 causes the first sprocket wheel 48 to rotate, and the rotation of the first sprocket wheel 48 causes the second sprocket wheel 49 to rotate through the chain 50, and the rotation of the second sprocket wheel 49 causes the second screw rod 45 to rotate, and the rotation of the first screw rod 41 and the second screw rod 45 causes the first threaded block 42 and the second threaded block 46 to move respectively, and the movement of the first threaded block 42 and the second threaded block 46 causes the first push plate 43 and The second push plate 47 moves, and the movement of the second push plate 47 will push the winding core 9 to move it, thereby making the winding core 9 sleeved on the cylinder 10, and at the same time the L-shaped block 17 is in the fixed hole to limit it, and then the push motor 2 outputs in the reverse direction, and the output of the push motor 2 will make the first push plate 43 and the second push plate 47 reset and move, when the first push plate 43 and the second push plate 47 are reset, the output motor 3 is started, and the output of the output motor 3 will make the movable column 11 rotate, and the rotation of the movable column 11 will make the round block 12 rotate, and the rotation of the round block 12 will make the cylinder 10 move in a circle, and when the cylinder 10 with the winding core 9 inserted is aligned with the rotating column 23, the output motor 3 stops outputting, and at the same time the multi-stage electric push rod 33 outputs, and the output of the multi-stage electric push rod 33 will make the movable block 35 move, and the movable The movement of block 35 will cause the fixed plate 36 to move. When the fixed plate 36 is inserted into the fixed hole, the boxboard is placed on top of the fixed plate 36, and then the output motor 3 is started to make the cylinder 10 move in a circle, so that the suction cup 18 is pressed against the top of the boxboard. When pressed against, the drive motor 4 is started, and the output of the drive motor 4 will cause the rotating column 23 to rotate. The rotation of the rotating column 23 will cause the L-shaped threaded plate 25 to reciprocate through the reciprocating threaded guide sleeve 24 and the guide rod. The reciprocating movement of the L-shaped threaded plate 25 will cause the pulling plate 26 to reciprocate through the fixing rod. When the back of the pulling plate 26 contacts the annular plate 14, the L-shaped threaded plate 25 continues to move, which will cause the pulling plate 26 to be squeezed and rotate to avoid. When the pulling plate 26 moves to the other side of the annular plate 14, the pulling plate 26 is on the elastic sheet. The L-shaped threaded plate 25 is reset under the action of 27, and is limited by the L-shaped threaded plate 25 and cannot rotate in the opposite direction. At this time, the L-shaped threaded plate 25 continues to rotate and pulls the annular plate 14 through the pulling plate 26. The annular plate 14 moves under the force. The movement of the annular plate 14 causes the moving block 13 to move. The movement of the moving block 13 causes the arc block 15 and the movable plate 22 to move. The movement of the movable plate 22 gives a pulling force to the connecting plate 21. The connecting plate 21 is forced to pull the moving plate 20 to move it. The movement of the moving plate 20 causes the piston 19 to move, and then the suction cup 18 adsorbs one end of the boxboard paper, thereby fixing the boxboard paper to avoid waste by fixing with glue. Then, the tension is regulated by the tension control module 51, and the arc block 15 contacts the rotating column 23 at the same time.Then, the movable block 35 and the fixed plate 36 are reset by the multi-stage electric push rod 33, and the movable block 13 continues to move. When the arc block 15 does not correspond to the arc groove, the movable block 13 continues to move, which causes the arc block 15 to be squeezed and retracted into the movable groove. When the arc block 15 corresponds to the arc groove, the arc block 15 enters the rotating column 23 under the action of the first spring 16. At this time, the rotation of the rotating column 23 causes the arc block 15 to rotate, and the rotation of the arc block 15 causes the movable block 13 to rotate. The rotation of the movable block 13 causes the cylinder 10 to rotate, and the rotation of the cylinder 10 causes the winding core 9 to rotate, thereby winding the boxboard paper. When the sensor 32 senses that the winding core 9 is wound, When the roll reaches a certain thickness, the driving motor 4 stops outputting, and the multi-stage electric push rod 33 outputs again. The multi-stage electric push rod 33 outputs again, which will move the movable block 35. The movement of the movable block 35 will move the lifting rod 37. The movement of the lifting rod 37 will move the L-shaped support plate and the horizontal block 38. The movement of the L-shaped support plate will move the fixed roller 40. The movement of the horizontal block 38 will be squeezed by the trapezoidal fixed block 34 and move downward. The downward movement of the horizontal block 38 will move the lifting rod 37 downward. The downward movement of the lifting rod 37 will move the fixed roller 40 downward through the L-shaped support plate, thereby squeezing the boxboard to fix it. When the fixation is completed, the multi-stage electric push rod 33 stops outputting, and then The rear cylinder 5 outputs, and the output of the cylinder 5 causes the cutting knife to descend to perform a cutting operation. When the cutting is completed, the fully automatic strapping machine 6 straps the rolled boxboard paper. When strapping is completed, the output motor 3 starts to rotate the round block 12, and the round block 12 causes the arc block 15 to pass under the arc groove. At the same time, the annular plate 14 contacts the trapezoidal extrusion block 29. At this time, the round block 12 continues to rotate, causing the annular plate 14 to be squeezed and reset. The reset movement of the annular plate 14 causes the movable block 13 to reset. The reset movement of the movable block 13 resets the piston 19 through the movable plate 20, the connecting plate 21 and the movable plate 22, and the reset of the piston 19 causes the suction cup 18 does not adsorb and fix the cardboard. At this time, since the cardboard is tied and fixed, the cardboard will not be loose. Then the round block 12 continues to move to make the cylinder 10 continue to move. When another cylinder 10 is aligned with another winding core 9, the output motor 3 stops outputting and the push motor 2 starts. The push motor 2 starts to move the first push plate 43 and the second push plate 47. The movement of the first push plate 43 will push the wound winding core 9, so that the winding core 9 moves to the second conveyor belt 8 for transportation. At the same time, the second push plate 47 pushes another winding core 9 to another cylinder 10, so as to load and unload materials, thereby positioning and replacing the winding core 9 and reducing manpower.

[0053] When the rolled-up core 9 is pushed, another core 9 will correspond to the fixed plate 36. At this time, the multi-stage electric push rod 33 continues to output to move the movable block 35, thereby making the box board paper contact with the suction cup 18. When the box board paper is fixed, the multi-stage electric push rod 33 contracts to reset the fixed plate 36. At this time, the fixed roller 40 will rotate. When the horizontal block 38 is not in contact with the trapezoidal fixed block 34, the horizontal block 38 will reset under the action of the second spring 39. The reset of the horizontal block 38 will reset the fixed roller 40, thereby releasing the fixation of the box board paper.

[0054] When the moving block 13 moves, the L-shaped clamping plate 30 will move together. The L-shaped clamping plate 30 will engage or disengage with the annular gear block 31, thereby limiting the cylinder 10 when the round block 12 rotates, thereby preventing the cylinder 10 from rotating during circular movement and causing the initial position to shift.

[0055] In the second embodiment, in order to make the arc block 15 move or rotate more stably, the electromagnet 28 can be activated to magnetically attract the arc block 15, thereby moving the arc block 15 or limiting it, so that the arc block 15 is connected to the rotating column 23 or its stability is increased.

[0056] The above is only a preferred embodiment of the present invention, and does not limit the present invention in other forms. Any technician familiar with the profession may use the above disclosed technical content to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment according to the technical essence of the present invention without departing from the technical solution of the present invention still belongs to the protection scope of the technical solution of the present invention.
