Description

Technical Field

[0001] This invention relates to the field of paper roll packaging technology, specifically a paper roll slitting and bundling device. Background Technology

[0002] Corrugated paper rolls are used for origami and handicrafts. They are usually packaged in large rolls and need to be manually separated after purchase. According to the required length, the long rolls are cut into individual pieces, then the cut rolls are flattened and tied together with binding materials (such as rubber bands, soft thread, etc.) for later use in origami. Manual separation requires cutting and tying the long rolls one by one, which requires standing for long periods of time. The operation is tedious, easily causing hand fatigue and discomfort, and is inefficient. The accuracy of manual separation is limited by the operator's skill level and cutting tools, which can easily lead to inconsistent lengths, significantly affecting the details and proportions of the origami illustrations. Moreover, the production cost is high, requiring a lot of labor, time and material costs, making it difficult to meet the needs of large-scale production. Summary of the Invention

[0025] like Figures 1-5 As shown, this embodiment provides a roll paper slitting and bundling device, which includes a conveying device 1, a slitting device 2, a pressing device 3, a conveying device 4, a bundling device, and a finished product table 6.

[0026] The conveying device 1 is used to convey the roll of paper to the slitting device 2, and includes a number of conveying rollers 11 arranged side by side. The conveying rollers 11 are existing technology and will not be described in detail here.

[0027] The slitting device 2 is used to slit the roll of paper into preset lengths to form rolls. It includes a turntable 21, an adsorption roller 22 mounted on the turntable 21 for adsorbing the roll of paper, a cutting mechanism 23 positioned above the adsorption roller 22 for cutting the roll of paper, a rotating mechanism 24 for driving the adsorption roller to rotate and form rolls, and a conveying mechanism 25 positioned below the adsorption roller 22 for conveying the rolls to the pressing device 3. The turntable 21 is driven to rotate by a rotary motor. The adsorption roller 22 includes at least two rollers; in this embodiment, three rollers are provided. Three adsorption rollers 22 are arranged along the circumference of the turntable 21 so that the paper roll contacts the outer surface of the three adsorption rollers 22. In order to cooperate with the three adsorption rollers 22 to adsorb the paper roll, two cloth rolling rollers 27 are arranged on each side of the three adsorption rollers 22. The cloth rolling rollers 27 are also arranged along the circumference of the turntable 21, and the three adsorption rollers 22 switch positions with the rotation of the turntable 21, which are divided into a cutting station and a conveying station. The cutting mechanism 23 includes a cutter 231 and a conveyor for driving the cutter 231 to move along the width direction of the paper roll to cut the paper roll. The moving assembly includes a moving cylinder 232 and a moving guide rail 233. A moving slider 234 is embedded in the moving guide rail 233. The cutter 231 is mounted on the moving slider 234. To cooperate with the cutting mechanism 23 in cutting the paper roll, a pressing mechanism 26 is provided on one side of the cutting mechanism 23. The pressing mechanism 26 includes a pressing plate 261 and a lifting assembly for driving the pressing plate 261 to rise and fall. The lifting assembly includes a crossbeam 262 and a cylinder 263 mounted on the crossbeam 262. The cylinder shaft of 3 is connected to the pressure plate 261. The adsorption roller 22 on the cutting station is located between the cutting mechanism 23 and the pressure mechanism 26. After the cutting mechanism 23 cuts the roll of paper, the rotating mechanism 24 located on the cutting station drives the adsorption roller 22 on the cutting station to rotate to form a split roll. The rotating mechanism 24 can be a rotary motor. The turntable 21 rotates, and the adsorption roller 22 located on the cutting station rotates to switch to the conveying station. The conveying mechanism 25 includes a roller 251 and a conveying motor 252 for driving the roller 251 to rotate to convey the split roll.

[0028] The pressing device 3 is located at one end of the conveying mechanism 25 along the conveying direction. It is used to receive the rolls conveyed by the conveying mechanism 25, flatten the rolls to form paper stacks, and push them to the bundling device. The pressing device 3 includes a pressing platform 31 at the same height as the roller 251, a pressing plate 32 set on the pressing platform 31, and a pressing motor 33 for driving the pressing plate 32 to move. This makes it convenient to convey the rolls to the pressing platform 31 through the roller 251. The pressing motor 33 drives the pressing plate 32 to move downward to flatten the rolls on the pressing platform 31 to form paper stacks.

[0029] The bundling device is used to absorb bundling tape, place the paper stack on the bundling tape, and bundle the paper stack with the bundling tape, then push it to the finished product table 6. The bundling device includes a rotating frame 51, a placement platform 52 for placing the bundling tape disposed on one side of the rotating frame 51, a bundling mechanism 53 mounted on the rotating frame 51, a first transfer mechanism 54 that moves between the placement platform 52 and the bundling mechanism 53 to place the bundling tape on the bundling mechanism 53, a second transfer mechanism 55 that moves between the pressing table 31 and the bundling mechanism 53 to place the paper stack on the bundling tape, and a third transfer mechanism 56 that moves between the bundling mechanism 53 and the finished product table 6 to transport the bundled paper stack to the finished product table 6. The rotating frame 51 is driven to rotate by a rotary motor. The bundling mechanism... At least two of the three binding mechanisms 53 are included; in this embodiment, three are provided. The three binding mechanisms 53 are arranged along the circumference of the rotating frame 51, and their positions change with the rotation of the rotating frame 51 to improve work efficiency. Each binding mechanism 53 includes a base plate 531, a flipping plate 532 disposed on both sides of the base plate 531 and of the same length as the base plate 531, and a flipping assembly for rotating the flipping plate 532 180° to cover the base plate 531, thereby connecting the folded edges of the binding strap to bind the paper stack. The flipping assembly includes a flipping shaft 533, the output end of which is connected to the flipping plate 532, and a gear 534 sleeved on the input end of the flipping shaft 533. The rotating frame 51 is provided with a transmission mechanism that communicates with the gear 534. The system includes a rack 535 with a moving engagement and a transmission cylinder 536 for driving the rack 535 to reciprocate. The width of the flipping plate 532 is smaller than the width of the base plate 531. When not flipped, the flipping plate 532 and the base plate 531 are on the same plane. When flipping, one side of the flipping plate 532 flips first, followed by the other side. After flipping 180°, the flipping plate 532 covers the base plate 531. The first transfer mechanism 54 is located on one side of the base plate 531 along its length and includes a suction cup frame 541 for picking up strapping and a moving component for moving the suction cup frame 541. The suction cup frame 541 has a square structure and is equipped with a suction cup and a suction component for moving the suction cup to pick up the strapping. The suction cup and suction component are existing technologies and will not be described in detail here. The moving assembly includes a transverse cylinder 542, a transverse guide rail 543, and a first lifting cylinder 544. A transverse slider 545 is embedded within the transverse guide rail 543. The first lifting cylinder 544 is mounted on the transverse slider 545 and is connected to a suction cup holder 541. The transverse cylinder 542 drives the transverse slider 545 to move along the transverse guide rail 543, thereby causing the first lifting cylinder 544 and the suction cup holder 541 to reciprocate between the placement platform 52 and the strapping mechanism 53. The first lifting cylinder 542 drives the suction cup holder 541 to move downwards at the placement platform 52 to pick up the strapping tape and then rises. At the strapping mechanism 53, it moves downwards to place the strapping tape on the base plate 531 and the flip plate 532 before rising again.The second transfer mechanism 55 includes a first pusher frame 551 and a first pusher assembly for driving the first pusher frame 551. The first pusher assembly includes a first pusher cylinder 552 and a first pusher guide rail 553. A first pusher slider 554 is embedded in the first pusher guide rail 553. The first pusher frame 551 is mounted on the first pusher slider 554. The first pusher cylinder 552 drives the first pusher slider 554 to move on the first pusher guide rail 553, so as to drive the first pusher frame 551 to push the paper stack on the pressure table 31 to the position of the base plate 531 and place it on the strapping. The first pusher frame 551 returns to the position of the pressure table 31. The third transfer mechanism 56 includes a second pusher frame 561 and a first pusher assembly for driving the first pusher frame 551. A first pushing assembly drives the second pushing frame 561. The second pushing assembly includes a second pushing cylinder, a second pushing guide rail 563, and a second lifting cylinder 565. A second pushing slider is embedded in the second pushing guide rail 563. The second lifting cylinder 565 is mounted on the second pushing slider. The second pushing frame 551 is mounted on the second lifting cylinder 565. When the second lifting cylinder 565 descends, it causes the second pushing frame 561 to descend. The second pushing cylinder causes the second pushing slider to move on the second pushing guide rail 563, thereby pushing the second pushing frame 561 to push the bundled paper stacks on the base plate 531 to the finished product table 6. When the second lifting cylinder 565 rises, the second pushing frame 561 returns to the position of the base plate 531.

[0030] The conveying device 4 is used to convey the strapping to the placement table 52. It includes a conveying table 41 and a conveying roller 42 disposed on the conveying table 41. The conveying table 41 and the placement table 52 are on the same plane. The height of the finished product table 6 is lower than the height of the base plate 531. The finished product table 6 is also a conveying platform on which the bundled paper stacks are stacked. The finished product table 6 is provided with a flattening mechanism for flattening the bundled paper stacks again. The flattening mechanism includes a pressing plate 61 and a flattening motor 62 for driving the pressing plate 61 to move.

[0031] Working principle: A large roll of paper is flattened and conveyed to the adsorption roller 22 via the conveyor roller 11. One of the adsorption rollers 22 switches to the cutting position as the turntable rotates. The cylinder 263 drives the pressure plate 261 to descend and press against the paper roll. The motion cylinder 232 drives the motion slider 234 to move on the motion guide rail 233, which in turn drives the cutter 231 to move along the width of the paper roll to cut it. Subsequently, the rotary motor at the cutting position drives the adsorption roller 22 at the cutting position to rotate and form a split roll. The turntable 21 continues to rotate, and the adsorption roller 22 at the cutting position rotates to switch to the conveying position. The conveyor motor 252 drives the roller 251 to rotate, and the split rolls are driven by the roller 251 from the adsorption roller. The 22 strip is ejected and conveyed to the pressing table 31. The pressing motor 33 drives the pressing plate 32 to move downward, flattening the rolls on the pressing table 31 to form a paper stack. The conveyor table 41 and the conveyor roller 42 convey the strapping to the placement table 52. The first lifting cylinder 542 drives the suction cup frame 541 to move downward at the position of the placement table 52 to pick up the strapping and then rise. The transverse cylinder 542 drives the transverse slider 545 to move on the transverse guide rail 543, so as to move the first lifting cylinder 544 and the suction cup frame 541 from the placement table 52 to the position of the bottom plate 531 and the flip plate 532. The first lifting cylinder 542 drives the suction cup frame 541 to move downward at the position of the placement table 52 to place the strapping on the bottom plate. After rising onto the platen 531 and flipping plate 532, the paper stack rises and then returns to the position of the placement table 52. The first pushing cylinder 552 drives the first pushing slider 554 to move on the first pushing guide rail 553, thereby driving the first pushing frame 551 to push the paper stack on the pressing table 31 to the position of the base plate 531 and place it on the strapping. The first pushing frame 551 returns to the position of the pressing table 31. The transmission cylinder 536 rotates, driving the rack 535 to move, which in turn drives the gear 534 to rotate, thereby driving the flipping plate 532 to flip. During the flipping, one side of the flipping plate 532 flips first, and then the other side flips. After flipping 180°, the flipping plate 532 covers the base plate 531, thereby driving the first strapping. The tail folds are joined together to firmly bind the paper stack. To prevent the bundle from coming apart, glue can be applied to one side of the binding tape to stick the ends of the binding tape together. The second lifting cylinder 565 descends, driving the second pusher 561 to descend as well. The second pusher cylinder drives the second pusher slider to move on the second pusher guide rail 563, thereby driving the second pusher 561 to push the bundled paper stack on the base plate 531 to the finished product table 6. The second lifting cylinder 565 rises, and the second pusher 561 returns to the position of the base plate 531, completing the entire cutting and binding process. The flattening motor 62 drives the flattening plate 61 to descend and press against the bundled paper stack, which is then transported to the next process for packaging via the finished product table 6.

[0032] This invention uses a turntable, adsorption roller, cutting mechanism, rotating mechanism, and conveying mechanism to adsorb, cut, slit, and transport paper rolls. It can accurately slit paper rolls according to preset lengths, ensuring that each roll is of consistent length. A pressing device flattens the rolls to form paper stacks, facilitating subsequent bundling, packaging, and transportation. Bundling with strapping tape makes the paper stacks easy to use. The entire process is completed in one piece of equipment, saving space and equipment investment. This equipment can automatically complete the paper cutting and bundling operations, improving production efficiency, reducing manual operation, and improving product quality and work efficiency.
