Description

Technical Field

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

[0002] Corrugated paper, also known as kraft paper or kraft cardboard, is one of the main paper types for cartons. It is mainly bonded with a corrugated paper core to form a corrugated cardboard box, which is used for packaging household appliances, daily necessities, cotton knitted fabrics, cultural supplies, and the outer packaging of traditional Chinese and Western patent medicines. During production, it is generally wound and stored through a flexible paper winding system. The flexible paper winding system generally includes a coil support device, a tension control system, a deviation rectification device, guide rollers, a tension detection system, a winding shaft, a pressure control device, and a tension control system for automatic regulation of winding to ensure the quality of the corrugated paper after winding. The existing winding methods are divided into two types: core winding and coreless winding.

[0003] During the existing core winding, generally, the core is first installed on the winding roller by plugging or clamping, and then one end of the corrugated paper is fixed to the core with glue or tape. Then, it is fixed by a fully automatic bundling machine when the winding is completed. However, fixing the corrugated paper to the core with glue or tape easily causes the pasted part to be unusable again, resulting in waste. At the same time, when fixed with glue, it is necessary to wait for a period of time or use a cooling device to cool and fix it before winding, which easily affects the processing progress and increases power consumption, making it inconvenient to use.

[0015] A method for a flexible paper winding system of a corrugated paper machine includes the following steps:

[0016] S1. First, place the core on the first conveyor belt through an external robotic arm and engage it with the arc-shaped limiting plate. Then start the first conveyor belt to convey the core. When the core is aligned with the cylinder, start the pushing motor. The output of the pushing motor will cause the first push plate and the second push plate to move, thereby sleeving the core onto the cylinder.

[0017] S2. Then start the output motor. The output of the output motor will cause the cylinder to perform circular motion, thereby aligning the core with the fixed plate. Then, use the multi-stage electric push rod to insert the fixed plate into the fixing hole on the core. At this time, the fixed roller fixes the corrugated paper.

[0018] S3. When the corrugated paper contacts the suction cup, start the driving motor. The output of the driving motor will first cause the suction cup to adsorb and fix the corrugated paper. At the same time, the multi-stage electric push rod contracts. Then, the driving motor drives the cylinder to rotate, thereby causing the core to wind the corrugated paper.

[0019] S4. When the winding is completed, first fix the corrugated paper with the fixed roller, then cut it with a cutting knife. When the cutting is completed, bundle it with a fully automatic bundling machine, so that it is not necessary to use glue for fixing, reducing waste.

[0020] S5. When the bundling is completed, the output of the output motor causes the wound core to be at the bottom. Then start the pushing motor. The output of the pushing motor will push the wound core and the unwound core through the first push plate and the second push plate, thereby causing the wound core to be conveyed through the second conveyor belt, so as to automatically align and replace the core, reducing labor.

[0021] The beneficial effects of the present invention compared with the prior art are as follows:

[0022] 1. Through the multi-stage electric push rod and the fixed plate, one end of the corrugated paper can be pushed to contact the suction cup. Then, the driving motor causes the rotating column to rotate. The rotation of the rotating column will cause the moving block to move through the pull plate and the annular plate. The movement of the moving block will first cause the piston to move. The movement of the piston will cause the suction cup to adsorb the corrugated paper, thereby fixing it. Then, the continuous movement of the moving block will be connected to the rotating column through the arc-shaped block. At this time, the rotation of the rotating column will cause the core to rotate through the cylinder, thereby winding the corrugated paper. When the winding is completed and the cutting is done, bundle it from the outside with a fully automatic bundling machine, thereby fixing the corrugated paper, avoiding waste caused by fixing it on the core with glue. At the same time, through the first conveyor belt, the second conveyor belt, the arc-shaped limiting plate, the first push plate and the second push plate, the wound and unwound cores can be automatically positioned and replaced, reducing labor.

[0023] 2. When the winding core is wound and performs circular motion, the trapezoidal extrusion block can reset the annular plate, and further reset the moving block. The reset of the moving block will cause the L-shaped clamping plate to be clamped with the annular tooth block, so as to limit the cylinder, thus avoiding the rotation of itself and the deviation from the initial position, which may affect the subsequent use.

[0024] 3. Through the settings of the lifting rod, horizontal block, L-shaped support plate, second spring and fixed roller, when pushing the corrugated paper, it can be limited, thus avoiding the warping of one end of the corrugated paper, which may affect 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 winding core and the unwound winding core can be replaced, avoiding the separate replacement, which may increase the replacement time and affect the processing progress.

[0046] Specifically, through the setting of the first spring 16, the arc-shaped block 15 can be contracted and avoided, so as to prevent the arc-shaped block 15 from getting stuck while continuously moving without aligning with the arc-shaped groove.

[0047] The lifting and fixing unit includes a lifting hole opened at the top of the movable block 35. A lifting rod 37 is slidably installed in the lifting hole.

[0054] In this solution, through the settings of the annular plate 14, the reciprocating threaded guide sleeve 24, the fixed rods, the pull plate 26 and the trapezoidal extrusion block 29, it is convenient to move the moving block 13.

[0055] Specifically, through the annular plate 14, the reciprocating threaded guide sleeve 24, the fixed rods and the pull plate 26, the moving block 13 can be moved, so that a connection relationship is generated between the arc-shaped block 15 and the rotating column 23.

[0058] Specifically, when the moving block 13 is in the initial position, it can be limited by the L-shaped clamping plate 30 and the annular tooth blocks 31. At the same time, under the action of the friction force of the piston 19, it is avoided that the cylinder 10 rotates during circumferential movement, resulting in an offset of the initial position.

[0059] A pushing motor 2 is installed on the side of the U-shaped base 1. A top plate 44 is installed on the top of the U-shaped base 1. Fixed grooves are formed on the inner wall of the top of the U-shaped base 1 and the bottom of the top plate 44.

A first push plate 43 and a second push plate 47 are respectively installed on the top of the first threaded block 42 and the bottom of the second threaded block 46. The first lead screw 41 and the second lead screw 45 are cooperatively installed through a transmission assembly.

[0060] In this solution, through the arrangement of the pushing motor 2, the top plate 44, the first lead screw 41, the second lead screw 45, the first threaded block 42, the second threaded block 46, the first push plate 43 and the second push plate 47, it is convenient to push the core 9.

[0061] Specifically, through the pushing motor 2, the top plate 44, the first lead screw 41, the second lead screw 45, the first threaded block 42 and the second threaded block 46, the first push plate 43 and the second push plate 47 can be moved. The first push plate 43 and the second push plate 47 will respectively push the wound core 9 and the unwound core 9, so as to replace the core 9.

[0062] The transmission assembly includes a first sprocket 48 and a second sprocket 49 respectively installed at one end of the first lead screw 41 and the second lead screw 45, and a chain 50 is commonly engaged and installed on the first sprocket 48 and the second sprocket 49.

[0063] In this solution, through the arrangement of the first sprocket 48, the second sprocket 49 and the chain 50, it is convenient to make the first lead screw 41 and the second lead screw 45 rotate simultaneously.

[0064] Specifically, through the arrangement of the first sprocket 48, the second sprocket 49 and the chain 50, the first push plate 43 and the second push plate 47 move simultaneously, so as to push the two cores 9 at the same time.

[0065] A method for a flexible paper winding system of a corrugated paper machine includes the following steps:

[0066] S1. First, place the core 9 on the first conveyor belt 7 through an external robotic arm and engage it with the arc-shaped limiting plate, and then start the first conveyor belt 7 to convey the core 9. When the core 9 is aligned with the cylinder 10, start the pushing motor 2. The output of the pushing motor 2 will cause the first push plate 43 and the second push plate 47 to move, and then the core 9 is sleeved on the cylinder 10;

[0067] S2. Then start the output motor 3. The output of the output motor 3 will cause the cylinder 10 to perform a circular motion, and then the core 9 is aligned with the fixing plate 36. Then, the fixing plate 36 is inserted into the fixing hole on the core 9 through the multi-stage electric push rod 33. At this time, the fixing roller 40 fixes the corrugated paper;

[0068] S3. When the corrugated paper contacts the suction cup 18, start the driving motor 4. The output of the driving motor 4 will first cause the suction cup 18 to adsorb and fix the corrugated paper, and at the same time, the multi-stage electric push rod 33 contracts. Then, the driving motor 4 drives the cylinder 10 to rotate, and then the core 9 winds the corrugated paper;

[0069] S4. When the winding is completed, first fix the corrugated paper with the fixed roller 40, then cut it with the cutting knife. When the cutting is completed, bundle it with the fully automatic bundling machine 6, so that fixing without glue can reduce waste.

[0070] S5. When the bundling is completed, the output motor 3 outputs to make the wound core 9 at the lowest position. Then the pushing motor 2 is started. The output of the pushing motor 2 will push the wound core 9 and the unwound core 9 through the first push plate 43 and the second push plate 47, so that the wound core 9 is conveyed through the second conveyor belt 8, thereby automatically aligning and replacing the core 9 and reducing manpower.

[0071] In order to make the arc block 15 move or rotate more stably, the following Embodiment 2 is provided. The following combines the attached Figure 9 to further optimize the present invention.

[0072] Install an electromagnet 28 on the inner wall of the side of the arc groove. The power cord of the electromagnet 28 is connected to an external power supply through a coupling. By starting the electromagnet 28, the electromagnet 28 adsorbs the arc block 15 to make it move, so that the electromagnet 28 contacts the arc block 15, thereby connecting the arc block 15 to the rotating column 23 or increasing its stability effect.

[0073] Working principle and usage process of the present invention: When in use, first place the core 9 on the first conveyor belt 7 by an external robotic arm or manually, and engage it with the arc-shaped limiting plate. Then start the first conveyor belt 7 to convey the core 9. When the core 9 is aligned with the cylinder 10, the pushing motor 2 is started. The output of the pushing motor 2 will cause the first lead screw 41 to rotate. The rotation of the first lead screw 41 will cause the first sprocket 48 to rotate. The rotation of the first sprocket 48 will cause the second sprocket 49 to rotate through the chain 50. The rotation of the second sprocket 49 will cause the second lead screw 45 to rotate. The rotation of the first lead screw 41 and the second lead screw 45 will cause the first threaded block 42 and the second threaded block 46 to move respectively. The movement of the first threaded block 42 and the second threaded block 46 will cause the first push plate 43 and the second push plate 47 to move. The movement of the second push plate 47 will push the core 9 to move, so that the core 9 is sleeved on the cylinder 10. At the same time, the L-shaped block 17 is in the fixing hole to limit it. Then the pushing motor 2 outputs in the reverse direction. The output of the pushing motor 2 will cause the first push plate 43 and the second push plate 47 to move back to their original positions. When the first push plate 43 and the second push plate 47 are reset, the output motor 3 is started. The output of the output motor 3 will cause the movable column 11 to rotate. The rotation of the movable column 11 will cause the round block 12 to rotate. The rotation of the round block 12 will cause the cylinder 10 to perform a circular motion. When the cylinder 10 with the core 9 inserted is aligned with the rotating column 23, the output of the output motor 3 stops. At the same time, the multi-stage electric push rod 33 outputs. The output of the multi-stage electric push rod 33 will cause the movable block 35 to move. The movement of the movable block 35 will cause the fixed plate 36 to move. When the fixed plate 36 is inserted into the fixing hole, place the box board paper above the fixed plate 36. Then start the output motor 3 to make the cylinder 10 perform a circular motion, so that the suction cup 18 is in close contact with the top of the box board paper. When it is in close contact, start the driving motor 4. The output of the driving 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 move back and forth through the reciprocating threaded guide sleeve 24 and the guide rod. The reciprocating movement of the L-shaped threaded plate 25 will cause the pull plate 26 to move back and forth through the fixed rod. When the back of the pull plate 26 contacts the annular plate 14, the continuous movement of the L-shaped threaded plate 25 will cause the pull plate 26 to be squeezed and rotate to avoid it. When the pull plate 26 moves to the other side of the annular plate 14, the pull plate 26 is reset under the action of the elastic piece 27 and is limited by the L-shaped threaded plate 25 and cannot rotate in the reverse direction. At this time, the continuous rotation of the L-shaped threaded plate 25 will pull the annular plate 14 through the pull plate 26. The annular plate 14 will move under the force. The movement of the annular plate 14 will cause the moving block 13 to move. The movement of the moving block 13 will cause the arc-shaped block 15 and the movable plate 22 to move. The movement of the movable plate 22 will give a pulling force to the connecting plate 21. The connecting plate 21 will pull the moving plate 20 to move under the force. The movement of the moving plate 20 will cause the piston 19 to move, so that the suction cup 18 adsorbs one end of the box board paper, thus fixing the box board paper and avoiding waste caused by fixing with glue. Then, the tension control module 51 is used to regulate the tension. At the same time, the arc-shaped block 15 will contact the rotating column 23.Then, the multi-stage electric push rod 33 is used to reset the movable block 35 and the fixed plate 36. At the same time, the moving block 13 continues to move. When the arc block 15 does not correspond to the arc groove, if the moving block 13 continues to move at this time, the arc block 15 will be squeezed and retracted into the movable groove. When the arc block 15 corresponds to the arc groove, the arc block 15 will enter the rotating column 23 under the action of the first spring 16. At this time, the rotation of the rotating column 23 will cause the arc block 15 to rotate. The rotation of the arc block 15 will cause the moving block 13 to rotate. The rotation of the moving block 13 will cause the cylinder 10 to rotate. The rotation of the cylinder 10 will cause the core 9 to rotate, thereby winding the corrugated paper. When the sensor 32 senses that the core 9 has been wound to a certain thickness, the drive motor 4 stops outputting, and the multi-stage electric push rod 33 outputs again. The output of the multi-stage electric push rod 33 again will cause the movable block 35 to move. The movement of the movable block 35 will cause the lifting rod 37 to move. The movement of the lifting rod 37 will cause the L-shaped support plate and the horizontal block 38 to move. The movement of the L-shaped support plate will cause the fixed roller 40 to move. 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 cause the lifting rod 37 to move downward. The downward movement of the lifting rod 37 will cause the fixed roller 40 to move downward through the L-shaped support plate, thereby squeezing the corrugated paper to fix it. When the fixing is completed, the multi-stage electric push rod 33 stops outputting. Then, the cylinder 5 outputs. The output of the cylinder 5 will cause the cutting knife to descend for cutting operation. When the cutting is completed, the fully automatic bundling machine 6 bundles the wound corrugated paper. When the bundling is completed, the output motor 3 starts, causing the round block 12 to rotate. The round block 12 will cause the arc block 15 to pass below the arc groove. At the same time, the annular plate 14 will contact the trapezoidal extrusion block 29. At this time, if the round block 12 continues to rotate, the annular plate 14 will be squeezed and reset. The reset movement of the annular plate 14 will cause the movable block 13 to reset. The reset movement of the movable block 13 will cause the piston 19 to reset through the moving plate 20, the connecting plate 21, and the movable plate 22. The reset of the piston 19 will cause the suction cup 18 not to adsorb and fix the corrugated paper. At this time, since the corrugated paper is bundled and fixed, the corrugated paper will not become loose. Then, the round block 12 continues to move, causing the cylinder 10 to continue to move. When another cylinder 10 aligns with another core 9, the output motor 3 stops outputting, and the pushing motor 2 starts. The start of the pushing motor 2 will cause the first push plate 43 and the second push plate 47 to move. The movement of the first push plate 43 will push the wound core 9, thereby causing the core 9 to move onto the second conveyor belt 8 for conveying. At the same time, the second push plate 47 pushes another core 9 onto another cylinder 10, thereby performing loading and unloading, and thus positioning and replacing the core 9, reducing labor.

[0074] When pushing the wound core 9, another core 9 will correspond to the fixed plate 36. At this time, the multi-stage electric push rod 33 continues to output to make the movable block 35 move, so that the corrugated paper contacts the suction cup 18. After the corrugated 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 does not contact the trapezoidal fixed block 34, the horizontal block 38 will reset under the action of the second spring 39, and the reset of the horizontal block 38 will cause the fixed roller 40 to reset, thereby releasing the fixation of the corrugated paper.

[0075] When the moving block 13 moves, it will cause the L-shaped clamping plate 30 to move together. The L-shaped clamping plate 30 moving together will be engaged or disengaged with the annular tooth block 31, so as to limit the cylinder 10 when the round block 12 rotates, thereby preventing the cylinder 10 from rotating when moving circumferentially and causing the initial position to shift.

[0076] In the second embodiment: In order to make the arc block 15 move or be more stable when rotating, the electromagnet 28 can be activated to magnetically attract the arc block 15, so as to make the arc block 15 move or limit it, so that the arc block 15 is connected to the rotating column 23 or its stability effect is increased.

[0077] The above is only a preferred embodiment of the present invention, and does not limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution content of the present invention still belong to the protection scope of the technical solution of the present invention.
