Description

Technical Field

[0001] This application relates to the field of rewinding technology, and in particular to a fully automatic rewinding machine for dust-free paper. Background Technology

[0002] Rewinding machines are generally used for rewinding and slitting mica tape, paper, and film, effectively splitting them in two. They are commonly used to slit wide rolls of material and play an important role in subsequent re-slitting. They are specialized equipment for paper, mica tape, and film.

[0003] In the traditional process of rewinding cleanroom paper, the prepared core needs to be placed in a preset position on the rewinding machine once. The first pushing device pushes the core into the rewinding area to achieve rewinding and winding. After rewinding, it is cut by a cutter. Then, the second pushing device pushes the rewound cleanroom paper core out of the rewinding area for unloading. In this process, the core cannot be automatically replenished to the preset position of the rewinding machine. At the same time, the core needs to use two different pushing devices to complete the rewinding process, which results in a long process time and low rewinding efficiency. Summary of the Invention

[0004] In order to improve the problem that existing rewinding machines cannot automatically replenish the shaft core and require two different pushing devices, resulting in a long process time, the purpose of this application is to provide a fully automatic rewinding machine for dust-free paper.

[0005] The fully automatic dust-free paper rewinding machine provided in this application adopts the following technical solution: The fully automatic rewinding machine for cleanroom paper includes a rewinding machine body, which is equipped with several rollers for cleanroom paper transmission, a core feeding mechanism, and a rewinding mechanism. The core feeding mechanism is used to store cores and realize automatic feeding. It includes a set of limiting plates and a feeding frame. The limiting plates are connected by several sliding rods. A feeding port that allows only a single core to pass through is opened at the bottom position between the limiting plates. The feeding frame is located directly below the feeding port. A discharge port is opened on the side of the feeding frame facing the rewinding mechanism. The rewinding mechanism includes a main rewinding shaft and a secondary rewinding shaft, which are arranged parallel to each other and have a gap between them. The end of the lint-free paper abuts against the main rewinding shaft and the secondary rewinding shaft in sequence and is laid flat at the gap. The rewinding machine body is provided with a pushing mechanism on the side of the unloading frame to push the shaft core from the unloading port to the gap. The shaft core is pressed against the lint-free paper. When the main rewinding shaft and the secondary rewinding shaft rotate to drive the shaft core to rotate in preparation for rewinding, the top of the shaft core moves against the pressing mechanism. After the shaft core is rewound, it continues to be pushed out by the pushing mechanism to remove it from the gap.

[0006] By adopting the above technical solution, the cleanroom paper is conveyed to the rewinding mechanism via several rollers. Multiple cores can be stored between a set of limiting plates. The cores automatically fall one at a time into the bottom feeding frame through the feeding port, and are then stacked vertically. When the pushing mechanism pushes the bottom core from the feeding port, the corresponding core at the top of the feeding frame automatically falls to the feeding port due to gravity. This structure enables automatic core replenishment without manual placement. Simultaneously, the pushing mechanism pushes the cores to be rewound to the gap on the rewinding mechanism. After the main and auxiliary rewinding shafts rotate and rewind the cores, the pushing mechanism can still push the rewounded cores out of the gap. During the rewinding process by the main and auxiliary rewinding shafts, the pushing mechanism abuts against the feeding port, and the cores inside the feeding frame are located at the top of the pushing mechanism. When the pushing mechanism pushes out the rewound shaft core, the pushing mechanism resets to the outside of the dropping frame. At this time, the bottommost shaft core in the dropping frame is still located at the unloading port. With this structure, only one pushing mechanism is needed to complete the pushing process of the shaft core to be rewound and the rewound shaft core, eliminating the need for two different pushing devices in the traditional structure.

[0007] Optionally, a driving component is also provided between a set of limiting plates to drive the limiting plates to slide in opposite directions along the slide rod. One side of the driving component is a forward threaded end and the other side is a reverse threaded end. When the driving component rotates, the distance between a set of limiting plates can be increased or decreased to adapt to the corresponding shaft core length storage.

[0008] By adopting the above technical solution, one side of the limiting plate is threadedly connected to the driving component with a positive thread end, and the other side of the limiting plate is threadedly connected to the driving component with a reverse thread. When the driving component rotates clockwise, the two limiting plates move inward along the slide rod, thereby reducing the distance between them. When the driving component rotates counterclockwise, the two limiting plates move outward along the slide rod, thereby increasing the distance between them. The adjustment of the distance between the two limiting plates is used to accommodate the placement of shaft cores of different lengths.

[0009] Optionally, the dropping frame is provided with several openings, through which the shaft cores fall into the dropping frame and are stacked vertically.

[0010] By adopting the above technical solution and setting several openings, it is easy for the pushing mechanism to extend into the openings and push the shaft core at the bottom of the dropping frame out from the unloading port. The shaft cores inside the dropping frame are stacked vertically, which makes it easy for the pushing mechanism to push out only one core at a time for rewinding, resulting in good production cycle efficiency.

[0011] Optionally, the pushing mechanism includes a pushing component and a pushing plate. The pushing component is fixedly mounted on the rewinding machine body, and the pushing plate is fixed on the driving end of the pushing component. The pushing plate passes through the through-hole and abuts against the shaft core located at the bottom of the feeding frame.

[0012] By adopting the above technical solution, the pusher controls the push plate to move to the opening of the dropping frame, so as to push one shaft core at a time. At the same time, when the push plate is at the opening, it can prevent the other shaft cores at the top of the dropping frame from falling to the discharge port automatically. When the push plate leaves the opening, the shaft cores at the top of the dropping frame can continue to fall to the discharge port under the influence of gravity to be pushed out, thus realizing the cyclic automatic feeding process.

[0013] Optionally, the height of the unloading port is set in the same plane as the top height of the main rewind and the auxiliary rewind, and the lint-free paper abuts against the top of the main rewind and the auxiliary rewind, with the end of the lint-free paper facing the unloading port.

[0014] By adopting the above technical solution, the height of the unloading port is level with the top height of the main rewinding shaft and the auxiliary rewinding shaft, which facilitates the pusher plate to horizontally push the shaft core from the unloading port to the gap. The main rewinding shaft and the auxiliary rewinding shaft drive the shaft core at the gap to wind and rewind the dust-free paper. The main rewinding shaft and the auxiliary rewinding shaft rotate in the same direction toward the unloading port, and the shaft core rotates in opposite directions due to the same thrust of the main rewinding shaft and the auxiliary rewinding shaft. The dust-free paper is wound along the rotation direction of the shaft core.

[0015] Optionally, the pressing mechanism includes a telescopic column, a connecting arm, and a pressing roller. The connecting arm is rotatably connected to both ends of the pressing roller, the pressing roller abuts against the shaft core, the connecting arm is fixedly mounted on the drive end of the telescopic column, and the telescopic column is fixed to the rewinder body.

[0016] By adopting the above technical solution, the pressing roller can be raised and lowered by the telescopic column. When the shaft core to be rewound is pushed into the gap, the pressing roller is driven by pressure and moves upward through the telescopic column, while abutting against the top of the shaft core. When the main rewinding shaft and the auxiliary rewinding shaft drive the shaft core to rotate and rewind, the pressing roller can prevent the shaft core from falling out of the gap, and at the same time, it can make the dust-free paper tightly rewound on the shaft core, and will not cause loose wrapping due to insufficient tension. The rotation direction of the pressing roller is the same as the rotation direction of the main rewinding shaft and the auxiliary rewinding shaft.

[0017] Optionally, the rewinding mechanism also includes an abutment roller located on the side of the main rewinding shaft. A reserved gap is provided between the abutment roller and the main rewinding shaft. The lint-free paper first abuts against the abutment roller and then extends to the main rewinding shaft and the auxiliary rewinding shaft.

[0018] By adopting the above technical solution, the abutment roller is used to assist the wrapping of the dust-free paper, and the reserved gap facilitates the sliding and cutting of the dust-free paper by the cutting mechanism, so that the cutting mechanism will not interfere with the corresponding position on the rewinder body, and avoids the cutting mechanism from interfering with the collision and causing breakage.

[0019] Optionally, a cutting mechanism is provided on the side of the rewinder body at the reserved gap. The cutting mechanism includes a first electric track and a cutter. A first straight groove is provided on the first electric track to facilitate the sliding of the cutter. After the core is rewound, the cutter slides along the reserved gap through the first straight groove to achieve the cutting of dust-free paper.

[0020] By adopting the above technical solution, the cutter slides in the first straight line on the first electric track. After the core is rewound with the dust-free paper, the cutter slides laterally along the reserved gap through the first electric track to achieve the cutting of the dust-free paper.

[0021] Optionally, a support roller for supporting the shaft core is provided on the outer side of the rewinder body. The shaft core with the dust-free cloth wound is pushed onto the support roller by a pushing mechanism. An auxiliary roller is provided on the side of the support roller to prevent the shaft core from detaching from the rewinder body.

[0022] By adopting the above technical solution, after the core is rewound with the dust-free paper, it is pushed onto the support roller from the gap through the pushing mechanism. During the pushing process, the core is pre-attached to the auxiliary roller, which reduces the flow intensity of the core and prevents the core from detaching from the support roller.

[0023] Optionally, the support roller also includes a pushing mechanism, which includes a second electric track and an abutment plate. The second electric track is provided with a second straight groove to facilitate the sliding of the abutment plate. A feeding plate is provided on one side of the support roller. The feeding plate is inclined to the rewinder body. The abutment plate is used to push the shaft core away from the support roller and slide onto the feeding plate.

[0024] By adopting the above technical solution, the abutment plate slides along the second straight groove on the second electric track. When the shaft core of the rewound dust-free paper falls onto the support roller, the abutment plate pushes the shaft core from the side to the unloading plate. With the inclined setting of the unloading plate, the shaft core falls directly into the prepared receiving box. By setting the unloading plate, the external receiving box is kept as far away from the equipment as possible, which facilitates the transfer and use of the receiving box.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. When the pushing mechanism pushes the bottommost shaft core in the dropping frame out of the unloading port, the corresponding top shaft core in the dropping frame automatically falls to the unloading port simultaneously under the influence of gravity. This structure can realize the automatic replenishment of shaft core feeding process without the need for manual placement once. At the same time, when the pushing mechanism pushes out the rewound shaft core, the pushing mechanism returns to the outside of the dropping frame. At this time, the bottommost shaft core in the dropping frame is still located at the unloading port. With this structure, only one pushing mechanism is needed to complete the pushing process of the shaft core to be rewound and the rewound shaft core, without the need for two different pushing devices in the traditional structure. 2. The spacing between the two limit plates can be easily adjusted by setting the drive component, which is used to adapt to the switching of different shaft core lengths; 3. By setting several openings, it is easy for the pushing mechanism to extend into the openings and push the shaft core at the bottom of the dropping frame out from the unloading port. The shaft cores inside the dropping frame are stacked vertically, which makes it easy for the pushing mechanism to push out only one core at a time for rewinding operation. 4. The pressing roller can prevent the shaft core from detaching from the gap, and at the same time, it can make the dust-free paper tightly rewound on the shaft core, so that the wrapping and bonding will not be loose due to insufficient tension. 5. By setting a reserved gap, the cutting mechanism can slide and cut the dust-free paper, so that the cutting mechanism will not interfere with the corresponding position on the rewinder body, and avoid the cutting mechanism from breaking due to interference and collision; 6. By setting up a discharge plate, the external receiving box is kept as far away from the equipment as possible, making it easier to move and use the receiving box. Attached Figure Description

Detailed Implementation

[0028] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail below.

[0029] Example 1: 120 fully automatic dust-free paper rewinding machine, refer to Figure 1 The rewinder includes a rewinder body 100, which is equipped with several rollers 110 for driving the clean paper 120, a core feeding mechanism 200, and a rewinding mechanism 300. The clean paper 120 is wound around the rollers 110 to achieve a certain tension. The core feeding mechanism 200 and the rewinding mechanism 300 are both fixedly installed on the rewinder body 100. The rewinding mechanism 300 is located to the side of the core feeding mechanism 200. The clean paper 120 is driven towards the rewinding mechanism 300, and the end of the clean paper 120 is connected to the rewinding mechanism 300. The core feeding mechanism 200 has multiple cores 150 for rewinding the clean paper 120.

[0030] Reference Figure 1 and Figure 2The shaft core blanking mechanism 200 includes a set of symmetrically distributed limiting plates 210 and blanking frames 230. The limiting plates 210 are movably connected by several sliding rods 211. A driving member 220 is also provided between the limiting plates 210. In this embodiment, the driving member 220 is a driving screw. One side of the driving member 220 has a forward threaded end 221, and the other side has a reverse threaded end 222. One limiting plate 210 is threadedly connected to the driving member 220 with the forward threaded end 221, and the other limiting plate 210 is threadedly connected to the driving member 220 with the reverse thread. When the drive component 220 rotates clockwise, the two limiting plates 210 move inward along the slide bar 211, reducing the distance between them. When the drive component 220 rotates counterclockwise, the two limiting plates 210 move outward along the slide bar 211, increasing the distance between them. The adjustment of the distance between the two limiting plates 210 is used to accommodate the placement of shaft cores 150 of different lengths. A discharge port 223, which allows only a single shaft core 150 to pass through, is provided at the bottom position between the limiting plates 210. The discharge frame 230 is located directly below the discharge port 223, and a descrambling port 231 is provided on the side of the discharge frame 230 facing the rewinding mechanism 300.

[0031] Reference Figure 2 and Figure 3 The discharge frame 230 is provided with several openings 232. The shaft cores 150 fall into the discharge frame 230 through the discharge openings 223 and are stacked vertically. The rewinder body 100 is provided with a pushing mechanism 400 on the side of the discharge frame 230 for pushing the shaft cores 150 out of the discharge port 231. The pushing mechanism 400 includes a pushing member 410 and a pushing plate 420. The pushing member is fixedly installed on the rewinder body 100, and the pushing plate 420 is fixed on the driving end of the pushing member 410. The pushing plate 420 passes through the openings 232 and abuts against the shaft core 150 at the bottom of the discharge frame 230. In this embodiment, the pushing member 410 is a telescopic cylinder. The pusher 410 controls the pusher plate 420 to move to the opening 232 of the dropping frame 230, so as to push one shaft core 150 at a time. At the same time, when the pusher plate 420 is located at the opening 232, it can prevent the remaining shaft cores 150 at the top of the dropping frame 230 from falling to the discharge port 231 automatically. When the pusher plate 420 leaves the opening 232, the shaft cores 150 at the top of the dropping frame 230 can continue to fall to the discharge port 231 under the influence of gravity to be ejected, thus realizing the cyclic automatic feeding process.

[0032] Reference Figure 3 , Figure 4 and Figure 5The rewinding mechanism 300 includes a main rewinding shaft 310 and an auxiliary rewinding shaft 320. A set of fixing plates 160 is provided on the side of the rewinder body 100 near the shaft core unloading mechanism 200. Both the rewinding shaft 310 and the auxiliary rewinding shaft 320 are rotatably connected to the fixing plates 160. The main rewinding shaft 310 and the auxiliary rewinding shaft 320 are arranged parallel to each other and have a gap 330 between them. The end of the lint-free paper 120 abuts against the main rewinding shaft 310 and the auxiliary rewinding shaft 320 in sequence and lies flat at the gap 330. The discharge port 231 is located at a height that is planar with the top height of the main rewinding shaft 310 and the auxiliary rewinding shaft 320. The lint-free paper 120 abuts against the top of the main rewinding shaft 310 and the auxiliary rewinding shaft 320, with the end of the lint-free paper 120 facing the discharge port 231. The pusher 410 pushes the pusher plate 420 into the through 232 of the discharge frame 230 and abuts against the shaft core 150, pushing the shaft core 150 from the discharge port 231 to the gap port 330, and pressing the shaft core 150 onto the dust-free paper 120. When the main rewinding shaft 310 and the auxiliary rewinding shaft 320 roll and drive the shaft core 150 to rotate in preparation for rewinding, the top of the shaft core 150 is movably abutted against the pressing mechanism 500.

[0033] It should be noted that after the main rewinding shaft 310 and the auxiliary rewinding shaft 320 rotate to rewind the shaft core 150, the rewound shaft core 150 can still be pushed out of the gap opening 330 by the pushing mechanism 400. During the rewinding process of the main rewinding shaft 310 and the auxiliary rewinding shaft 320, the pushing mechanism 400 abuts against the discharge opening 223, and the shaft core 150 inside the discharge frame 230 is located at the top of the pushing mechanism 400. When the pushing mechanism 400 pushes out the rewound shaft core 150, the pushing mechanism 400 returns to the outside of the discharge frame 230. At this time, the bottommost shaft core 150 inside the discharge frame 230 is still located at the unloading opening 231.

[0034] Reference Figure 5 and Figure 6The pressing mechanism 500 includes a telescopic column 510, a connecting arm 520, and a pressing roller 530. The connecting arm 520 is rotatably connected to both ends of the pressing roller 530. The pressing roller 530 abuts against the top of the shaft core 150. The connecting arm 520 is fixedly mounted on the driving end of the telescopic column 510. The telescopic column 510 is fixed on the rewinder body 100. The pressing roller 530 moves up and down via the telescopic column 510. When the core 150 to be rewound is pushed into the gap 330, the pressing roller 530 is driven by pressure and moves upward through the telescopic column 510, while simultaneously abutting against the top of the core 150. When the main rewinding shaft 310 and the auxiliary rewinding shaft 320 drive the core 150 to rotate and rewind, the pressing roller 530 can prevent the core 150 from falling out of the gap 330, and at the same time can ensure that the dust-free paper 120 is tightly rewound on the core 150, without the filaments being loosely wrapped due to insufficient tension. The rotation direction of the pressing roller 530 is the same as the rotation direction of the main rewinding shaft 310 and the auxiliary rewinding shaft 320.

[0035] Reference Figure 6 The rewinding mechanism 300 also includes an abutment roller 340, which is located on the side of the main rewinding shaft 310 and rotatably connected to the fixed plate 160. A reserved gap 350 is provided between the abutment roller 340 and the main rewinding shaft 310. The lint-free paper 120 first abuts against the abutment roller 340 and then extends to the main rewinding shaft 310 and the auxiliary rewinding shaft 320. The abutment roller 340 is used to assist the lint-free paper 120 in winding, and the reserved gap 350 facilitates the sliding and cutting of the lint-free paper 120 by the cutting mechanism 600, so that the cutting mechanism 600 will not interfere with the corresponding position on the rewinder body 100, and avoids breakage caused by interference and collision of the cutting mechanism 600.

[0036] The rewinder body 100 is provided with a cutting mechanism 600 on the side of the reserved gap 350. The cutting mechanism 600 includes a first electric track 610 and a cutter 630. The first electric track 610 is provided with a first straight groove 620 to facilitate the sliding of the cutter 630. The cutter 630 slides in the first straight groove on the first electric track 610. After the core 150 rewinds the dust-free paper 120, the cutter 630 slides laterally along the reserved gap 350 through the first electric track 610 to achieve the cutting of the dust-free paper 120.

[0037] Reference Figure 1As shown, a support roller 130 for supporting the unloading of the shaft core 150 is provided on the outer side of the rewinder body 100. The shaft core 150, after being rolled with clean paper, is pushed down onto the support roller 130 by the pushing mechanism 400 and temporarily placed there. An auxiliary roller 140 is provided on the side of the support roller 130 to prevent the shaft core 150 from detaching from the rewinder body 100. The two ends of the auxiliary roller 140 are rotatably connected to the rewinder body 100. After the shaft core 150 is rewound with the clean paper 120, it is pushed again from the gap 330 onto the support roller 130 by the pushing mechanism 400. During the pushing process, the shaft core 150 is pre-aggregated against the auxiliary roller 140. The auxiliary roller 140 reduces the flow intensity of the shaft core 150 and prevents the shaft core 150 from detaching from the support roller 130.

[0038] The support roller 130 also includes a pushing mechanism 700, which includes a second electric track 710 and an abutment plate 730. The second electric track 710 is provided with a second straight groove 720 to facilitate the sliding of the abutment plate 730. A discharge plate 740 is provided on one side of the support roller 130. The discharge plate 740 is inclined to the rewinder body 100. The abutment plate 730 is used to push the shaft core 150 away from the support roller 130 and slide it onto the discharge plate 740. When the shaft core 150 of the rewound dust-free paper 120 falls onto the support roller 130, the abutment plate 730 pushes the shaft core 150 from the side of the shaft core 150 to the discharge plate 740. With the inclined setting of the discharge plate 740, the shaft core 150 falls directly into the prepared receiving box (not shown in the figure). By setting the discharge plate 740, the external receiving box is kept as far away from the equipment as possible, which facilitates the transfer and use of the receiving box.

[0039] It should be noted that in this embodiment, a labeling mechanism 800 is provided on the side of the support roller 130. The labeling mechanism 800 is used to sequentially label the rewound shaft core 150.

[0040] The implementation principle of this application embodiment is as follows: The dust-free paper 120 is conveyed to the gap 330 position of the rewinding mechanism 300 through several rollers 110. The shaft cores 150 to be rolled are automatically dropped one at a time into the bottom dropping frame 230 through the dropping port 223, and are stacked vertically by one through the dropping frame 230. When the pushing mechanism 400 pushes the bottom shaft core 150 in the dropping frame 230 out of the unloading port 231, the corresponding top shaft core 150 in the dropping frame 230 is automatically dropped to the unloading port 231 simultaneously under the influence of gravity. The pusher mechanism 400 pushes the core 150 to be rewound to the gap 330 on the rewinding mechanism 300. The core 150 is pressed onto the cleanroom cloth 120. The main rewinding shaft 310 and the auxiliary rewinding shaft 320 rotate in the same direction toward the discharge port 223, driving the core 150 to rotate in the opposite direction to realize the rewinding of the cleanroom cloth. During the rotation of the core 150, the pressing mechanism 500 abuts against the top of the core 150 to prevent the core 150 from falling off the gap 330. At the same time, it can make the cleanroom cloth 120 tightly rewound onto the core 150, and prevent the wrapping from being loose due to insufficient tension.

[0041] After the shaft core 150 is rewound, the cutter 630 slides laterally along the reserved gap 350 via the first electric track 610 to cut the dust-free paper 120. Then, the pushing mechanism 400 continues to extend and retract toward the shaft core 150, pushing the shaft core 150 from the gap 330 onto the support roller 130. The labeling mechanism 800 performs the labeling operation on the shaft core 150. Finally, the abutment plate 730 pushes the shaft core 150 from the side to the unloading plate 740. With the inclined setting of the unloading plate 740, the shaft core 150 falls directly into the prepared receiving box for storage.

[0042] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.

After the shaft core is rewound, the pushing mechanism continues to push the rewounded shaft core out of the gap. After pushing out the rewounded shaft core, the pushing mechanism returns to the outside of the discharge frame. At this time, the bottom shaft core in the discharge frame is located at the discharge port, waiting for the next push. The rewinding mechanism also includes an abutment roller, which is located on the side of the main rewinding shaft. A reserved gap is provided between the abutment roller and the main rewinding shaft. The dust-free paper first abuts against the abutment roller and then extends to the main rewinding shaft and the auxiliary rewinding shaft. The rewinding machine body is equipped with a cutting mechanism on the side of the reserved gap. The cutting mechanism includes a first electric track and a cutter. The first electric track is provided with a first straight groove to facilitate the sliding of the cutter. After the core is rewound, the cutter slides along the reserved gap through the first straight groove to cut the dust-free paper. Then the pushing mechanism extends and retracts toward the core to push the core out from the gap opening.
