A multi-roll edge tape automatic paper receiving system

Abstract

This invention discloses an automatic paper splicing system for multi-roll edge sealing tape, comprising a paper feeder, a paper splicing reel assembly, a paper conveying reel, a paper splicing mechanism, and an intermediate conveyor line. The paper splicing mechanism is used to connect the paper splice from one of the paper feeders to the end of the paper splice being transported by the paper feeder that is about to run out of paper at the paper splicing reel assembly. The intermediate conveyor line provides conveying rollers and transfer rollers to transport the paper splice from the paper feeders to the paper splicing reel assembly. The paper splicing mechanism is driven to perform the splicing operation when the end of the paper splice reaches the transfer roller at the end. This invention transports the end of the paper splice from the paper feeder to the paper splicing reel assembly, ensuring that the paper splice remains taut throughout the transport process. The splicing occurs when the end of the paper splice passes the end of the intermediate conveyor line, shortening the overlap between the paper splices, ensuring complete adhesion of the overlapping parts, guaranteeing the stability of the splicing process, and improving the final production quality of gypsum board.

Description

Technical Field

[0001] This invention relates to the field of gypsum board production technology, specifically to an automatic paper splicing system for multi-roll edge banding tape. Background Technology

[0002] In the production process of gypsum board, paper needs to be attached to the surface of the gypsum board and processed into boards. New paper rolls need to be replaced manually. The production cycle of gypsum board is long and the production efficiency is low. During the processing, a paper splicing machine supplies paper to the gypsum board production line to achieve uninterrupted continuous paper feeding. The paper splicing machine achieves continuous paper splicing by bonding new and old paper rolls. However, when the paper roll on the next roll is used up, it is impossible to bond the paper roll on the previous roll, which affects the continuity of paper splicing. Therefore, when a roll of paper is used up, the splicing device is usually used to bond the splicing end of another roll of paper to the splicing end of the roll of paper. There is a certain distance between the splicing device and the paper feeder. If paper splicing is carried out when the splicing end of the paper feeder is detected to be used up, there will be a long overlap between the splicing end and the bonded splicing, and it is impossible to guarantee complete bonding of the overlapping part of the splicing. Secondary overlap is likely to occur during transportation, which affects the production quality of gypsum board.

[0003] Therefore, the existing paper splicing machine has the following technical problems: after the existing paper splicing machine completes the splicing, there is a long overlap between the spliced ​​parts, which cannot guarantee the complete adhesion of the overlapping parts. This makes it easy for secondary overlap to occur during transportation, affecting the final production quality of gypsum board. Summary of the Invention

[0004] To address this issue, the present invention provides an automatic paper splicing system for multi-roll edge banding tape, which effectively solves the problem in the prior art where the paper splicing machine has a long overlapping portion after splicing, which cannot guarantee complete adhesion of the overlapping portion and leads to secondary overlap during transportation, affecting the final production quality of gypsum board.

[0013] The conveying roller and the transmission roller form a conveying roller group. The paper receiving clamp is held between the conveying roller group. The conveying drive component is used to drive the conveying roller group to rotate so as to transport the paper receiving. The paper receiving conveying mechanism is provided with an extension drive structure on its side. The extension drive structure is used to drive the conveying roller groups on both sides to move so as to adjust the distance between the conveying roller groups.

[0014] Furthermore, the paper receiving and conveying mechanism includes a drive shaft coaxially connected to the conveying roller, a connecting shaft coaxially connected to the conveying roller, and a mounting bracket disposed on the side of the drive shaft and the connecting shaft;

[0015] Both the connecting shaft and the drive shaft are mounted on the mounting bracket, and adjacent drive shafts, adjacent connecting shafts, and the drive shaft and connecting shaft are connected by a transmission belt.

[0021] Furthermore, the extension drive structure includes connecting teeth disposed outside the connecting cylinder, a drive cavity disposed inside the inner wall of the drive frame near the connecting cylinder, a hydraulic cylinder disposed inside the drive cavity, and a snap-fit ​​tooth plate connected to the output end of the hydraulic cylinder.

[0022] The hydraulic cylinder drives the engaging toothed plate to engage with the connecting tooth.

[0023] Furthermore, the paper receiving roll assembly consists of a first paper receiving roll and a second paper receiving roll. The first paper receiving roll and the second paper receiving roll are provided with translation shafts. The first paper receiving roll and the translation shaft, and the second paper receiving roll and the translation shaft are integral structures and can rotate.

[0024] The annular groove is disposed on the outer wall of the first paper receiving roll and the second paper receiving roll, and the length of the annular groove is the same as the length of the conveying roller.

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] like Figure 1As shown, this invention provides an automatic paper splicing system for multi-roll edge sealing tape, comprising a paper feeder 1, a paper splicing reel assembly 21, a paper conveying reel 6, a paper splicing mechanism 2, and an intermediate conveyor line 3. The paper feeder 1 is used to supply paper to the gypsum board production line; there are two paper feeders 1, which feed paper alternately. The paper splicing reel assembly 21, corresponding to the paper feeder 1, is located downstream of the paper feeder 1 and is used to receive the paper splices 4 from the paper feeder 1 and drive the paper splices 4 forward. The paper conveying reel 6, located downstream of the paper splice assembly 21, receives the paper splices 4 conveyed by the paper splice assembly 21 and carries them forward. The paper splice 4 is transported forward to the gypsum board production line; the paper splicing mechanism 2 is connected to the bottom of the paper splicing roll assembly 21. The paper splicing mechanism 2 is used to drive the paper splice 4 on one of the paper feeders 1 to the end of the paper splice 4 transported by the paper feeder 1 when the paper splice 4 is about to be used up; the intermediate conveyor line 3 is set between the paper feeder 1 and the paper splicing roll assembly 21. The intermediate conveyor line 3 is used to provide conveyor rollers 3111 and transfer rollers 3112 to transport the paper splice 4 on the paper feeder 1 to the paper splicing roll assembly 21. The paper splicing mechanism 2 is driven to perform the paper splicing operation when the end of the paper splice 4 reaches the transfer roller at the end.

[0049] This invention provides an embodiment of the invention that, by setting an intermediate conveyor line 3 between the paper feeder 1 and the paper receiving roll group 21, conveys the end of the paper receiving roll 4 from the paper feeder 1 to the paper receiving roll group 21. This ensures that the paper receiving roll 4 remains taut throughout the conveying process. The paper receiving roll 4 is spliced ​​when it passes the end of the intermediate conveyor line 3, which shortens the overlapping portion between the paper receiving rolls 4, ensures complete adhesion of the overlapping portion of the paper receiving roll 4, guarantees the stability of the splicing process, and improves the final production quality of gypsum board.

[0050] There is a certain gap between the contact surface of the end conveyor roller 3112 and the contact surface of the paper receiver 4 and the contact surface of the paper receiver roll assembly 21 and the paper receiver 4, so that the paper receiver 4 is in a relaxed state after it leaves the conveyor roller 3112. In order to perform paper receiving when the paper receiver 4 is in a taut state, the paper receiving needs to be performed near the last conveyor roller 3112 at the end of the paper receiver 4. In order to minimize the overlap of the paper receiver 4, the distance between the contact apex above the conveyor roller 3112 and the paper receiver roll assembly 21 needs to be minimized. In order to reduce the distance between the conveyor roller 3112 and the paper receiver roll assembly 21, the present invention makes the radius of the conveyor roller 3112 near the paper receiver roll assembly 21 gradually decrease. The outer wall of the paper receiver roll assembly 21 is provided with an annular groove 214, and the end of the conveyor roller 3112 partially enters the annular groove 214. The contact surfaces of the conveyor roller 111, the conveyor roller 3112 and the paper receiver roll assembly 21 and the paper receiver 4 are all on the same horizontal plane.

[0051] To facilitate the transfer of the paper feeder 4 between the paper feeder 1 and the paper feed roll assembly 21, the intermediate conveyor line 3 includes a paper feed conveying mechanism 31 and a conveying drive component 32. The conveying roller 3111 and the conveying roller 3112 form a conveying roller assembly 311, and the paper feeder 4 is held between the conveying roller assemblies 311. The conveying drive component 32 is used to drive the conveying roller assembly 311 to rotate so as to transport the paper feeder 4. The paper feed conveying mechanism 31 is provided with an extension drive structure 33 on its side. The extension drive structure 33 is used to drive the conveying roller assemblies 311 on both sides to move so as to adjust the distance between the conveying roller assemblies 311.

[0052] In order to monitor the position of the paper feed 4 in real time, a position monitoring element 5 is provided on the conveyor roller group 311. The position detection element 5 is used to detect the paper feed 4 on the conveyor roller group 311, and to issue an alarm signal when the end of the paper feed 4 passes the end of the conveyor roller group 311 and to issue a disengagement prompt signal when the end of the paper feed 4 completely disengages from the conveyor roller group 311. According to the alarm signal, the paper feed mechanism 2 drives the head of the paper feed 4 on another paper feeder 1 to connect with the paper feed 4 on the paper feed roll group 21. The extension drive structure 33 drives the opposite conveyor roller groups 311 to move away from each other according to the disengagement prompt signal, so that an installation channel for the paper feed 4 to pass through is formed between the conveyor roller groups 311.

[0053] To facilitate the forward transport of the paper splice 4, this invention includes a paper splice conveying mechanism 31. The paper splice conveying mechanism 31 of this invention primarily adopts the following preferred embodiments, such as... Figure 4 As shown, the paper feeding mechanism 31 includes a drive shaft 312 coaxially connected to the conveying roller 3111, a connecting shaft 313 coaxially connected to the conveying roller 3112, and a mounting frame 314 disposed on the sides of the drive shaft 312 and the connecting shaft 313; the connecting shaft 313 and the drive shaft 312 are both mounted on the mounting frame 314, and adjacent drive shafts 312, adjacent connecting shafts 313, and drive shafts 312 and connecting shafts 313 are all connected by a transmission belt 315.

[0054] Therefore, in the above embodiment, it is only necessary to drive one or more drive shafts 312 to rotate, which can drive the remaining drive shafts 312 and connecting shafts 313 to rotate, so as to drive the paper feed 4 to be transported forward.

[0055] In order to ensure that the paper splice 4 is transported forward at a constant speed, the conveyor roller 3111 and the transfer roller 3112 need to have the same linear speed. Since the conveyor roller 3111 and the transfer roller 3112 have different radii, and the drive shaft 312 and the connecting shaft 313 have the same rotational linear speed, the drive shaft 312 and the connecting shaft 313 need to rotate at corresponding different angular velocities. Therefore, the drive shaft 312 and the connecting shaft 313 need to be set to specific radii so that the conveyor roller 3111 and the transfer roller 3112 are transported forward at the same linear speed.

[0056] In order to drive the drive shaft 312 to rotate so as to transport the paper 4 forward via the rotation of the conveying roller 3111 and the transfer roller 3112, the conveying drive component 32 of the present invention mainly adopts the following preferred embodiments, such as... Figure 3 As shown, the conveying drive component 32 includes a drive frame 321, a transmission worm gear 322 connected to a plurality of drive shafts 312 therein, a transmission worm 323 meshing with the side of the transmission worm gear 322, a connecting cylinder 324 connected to the lower end of the transmission worm 323, and a threaded post 325 threadedly connected to the bottom of the connecting cylinder 324; a second drive motor 326 is provided at the bottom of the threaded post 325, the second drive motor 326 is provided on the drive frame 321, and the threaded post 325 is connected to the output end of the second drive motor 326.

[0057] In the above embodiment, the driving process of the conveying drive component 32 is as follows: the second drive motor 326 drives the threaded column 325 to rotate, thereby driving the transmission worm 323 to rotate through the connecting cylinder 324. The transmission worm 323 drives the transmission worm wheel 322 to rotate, thereby driving the drive shaft 312 to rotate, thus driving the conveying roller 3111 and the conveying roller 3112 to rotate.

[0058] In the aforementioned driving process, it is necessary for the rotation of the threaded post 325 to drive the rotation of the connecting cylinder 324. To ensure that the rotation of the threaded post 325 can drive the rotation of the connecting cylinder 324, the present invention also incorporates the following design: Figure 6 As shown, an adjusting frame 327 is provided on the connecting cylinder 324. Both the drive shaft 312 and the connecting shaft 313 pass through the adjusting frame 327. The connecting cylinder 324 is provided through the bottom surface of the adjusting frame 327. A limit bolt 328 is provided near the connection point between the connecting cylinder 324 and the adjusting frame 327. A drive chamber 329 is provided at the end of the connecting cylinder 324. A drive cylinder 3210 is provided outside the drive chamber 329. A drive cylinder 3211 is provided inside the drive cylinder 3210. A connecting arc plate 3212 is connected to the output end of the drive cylinder 3211. A locking tooth 3213 is provided on the end face of the connecting arc plate 3212 that abuts against the threaded post 325. The locking tooth 3213 fits into the inner groove of the threaded post 325.

[0059] The drive cylinder 3211 drives the connecting arc plate 3212 to move forward, so that the locking teeth 3213 are locked in the inner groove of the threaded post 325. At this time, the threaded post 325 and the connecting cylinder 324 are limited and cannot rotate relative to each other. Therefore, when the threaded post 325 rotates, it can directly drive the connecting cylinder 324 to rotate.

[0060] In the above embodiments, the forward movement of the connecting arc plate 3212 to engage the locking teeth 3213 within the inner groove of the threaded post 325 requires that the locking teeth 3213 correspond to the inner groove of the threaded post 325. Otherwise, the locking teeth 3213 may directly contact the threaded protrusion on the threaded post 325. To ensure that the locking teeth 3213 correspond to the inner groove of the threaded post 325 before the connecting arc plate 3213 moves forward, the present invention makes the following design, as follows: Figure 5 As shown, a gear ring 3214 is provided outside the drive cylinder 3210, and a drive gear 3215 is meshed on the side of the gear ring 3214. A third drive motor 3216 is connected to the drive gear 3215, and the drive gear 3215 is connected to the output end of the third drive motor 3216.

[0061] The third drive motor 3216 drives the drive gear 3215 to rotate, which in turn drives the gear ring 3214 to rotate. The gear ring 3214 drives the drive cylinder 3210 to rotate, which in turn drives the drive cylinder 3211 and the connecting arc plate 3212 to rotate, so that the connecting arc plate 3212 rotates until the locking teeth 3213 on it correspond to the inner groove of the threaded post 325. At this time, the drive cylinder 3211 can drive the locking teeth 3213 to engage in the inner groove of the threaded post 325.

[0062] This invention mainly employs an extension drive structure 33 to drive the overall extension and retraction of the conveyor roller assembly 311. The extension drive structure 33 mainly adopts the following preferred embodiments, such as... Figure 5 As shown, the extension drive structure 33 includes a connecting tooth 331 disposed outside the connecting cylinder 324, a drive cavity 332 disposed inside the inner wall of the drive frame 321 near the connecting cylinder 324, a hydraulic cylinder 333 disposed inside the drive cavity 332, and a snap-fit ​​tooth plate 334 connected to the output end of the hydraulic cylinder 333; the hydraulic cylinder 333 is driven to move the snap-fit ​​tooth plate 334 to snap-fit ​​with the connecting tooth 331.

[0063] The driving principle of the extension drive structure 33 is as follows: the hydraulic cylinder 333 drives the snap-fit ​​toothed plate 334 to snap into the connecting tooth 331. At this time, the connecting cylinder 324 is limited and cannot rotate. The second drive motor 326 drives the threaded column 325 to rotate. Under the rotation of the threaded column 325 and the limiting action of the snap-fit ​​toothed plate 334, the connecting cylinder 324 gradually moves closer to the threaded column 325. This causes the adjusting frame 327 to move closer to the threaded column 325 through the connecting bolt 328. This causes the conveying roller group 311 to move inward, and the distance between the two conveying roller groups 311 gradually increases.

[0064] In this invention, the paper receiving roll assembly 21 performs paper receiving and conveying operations. The paper receiving roll assembly 21 consists of a first paper receiving roll 211 and a second paper receiving roll 212. The first paper receiving roll 211 and the second paper receiving roll 212 are provided with translation shafts 213. The first paper receiving roll 211 and the translation shaft 213, the second paper receiving roll 212 and the translation shaft 213 are an integral structure and can rotate. An annular groove 214 is provided on the outer wall of the first paper receiving roll 211 and the second paper receiving roll 212. The length of the annular groove 214 is the same as the length of the conveying roller 3112.

[0065] The inner annular grooves 214 of the first paper receiving roll 211 and the second paper receiving roll 212 are provided so that the conveying roller 3112 can enter the interior of the first paper receiving roll 211 and the second paper receiving roll 212 to reduce the size of the paper receiving overlap.

[0066] This invention employs a paper-receiving mechanism 2 to connect the paper feeder 4 from one of the paper feeders 1 to the end of the paper feeder 4 being transported by the paper feeder 1 when the paper feeder 4 is about to run out. The paper-receiving mechanism 2 of this invention mainly adopts the following preferred embodiments, such as... Figure 7 As shown, the paper receiving mechanism 2 includes a translation seat 22 disposed at the bottom of the translation shaft 213, a mounting platform 23 disposed at the bottom of the translation seat 22, a mounting groove 24 disposed in the mounting platform 23, and a first drive motor 25 and a drive threaded rod 26 disposed in the mounting groove 24; a rotary motor 27 is disposed in the translation seat 22, the translation shaft 213 is connected to the output end of the rotary motor 27, the drive threaded rod 26 is connected to the output end of the first drive motor 25, the drive threaded rod 26 is connected to the bottom of the translation seat 22, and the translation seat 22 slides in the mounting groove 24.

[0067] The first drive motor 25 drives the drive threaded rod 26 to rotate. Under the rotation of the drive threaded rod 26, the translation seat 22 gradually moves to be close to the corresponding other paper receiving roll until the two paper receiving rolls come into contact. At this time, the paper on the two paper receiving rolls contacts and sticks together. After the paper receiving is completed, the first drive motor 25 resets.

[0068] In order to drive the paper feeder 4 forward for feeding, a pair of paper feeder spools 6 are provided at the downstream end of the paper feeder spool group 21, and the paper feeder 4 is arranged between the paper feeder spools 6. In addition, in order to provide sufficient installation space for the paper feeder conveyor 31 on both sides and to make the distance between the translation seats 22 smaller (which can shorten the paper feed time to a certain extent), the present invention is designed as follows: the distance between the paper feeders 1 is a, and the distance between the first paper feeder spool 211 and the second paper feeder spool 212 is b, wherein a is greater than b.

[0069] In summary, the main implementation process of this invention is as follows: Paper feeder 4 on one of the paper feeders 1 is pre-fed; a third drive motor 3216 drives the drive gear 3215 to rotate, causing the connecting arc plate 3212 to rotate until the engaging teeth 3213 on it align with the inner groove of the threaded post 325. At this time, the drive cylinder 3211 can drive the engaging teeth 3213 to engage in the inner groove of the threaded post 325; a second drive motor 326 drives the threaded post 325 to rotate, thereby driving the drive shaft 312 to rotate, thus driving the conveying roller 3111 and the transfer roller 3112 to rotate; a first drive motor 25 drives the first paper feeder roll 211 and the second paper feeder roll 212 to rotate; the paper feeder roll 6 rotates, and the above structure rotates, causing the paper feeder 4 to be transported forward. The position detection element 5 monitors the position of the paper feeder 4 in real time, and issues an alarm signal when the end of the paper feeder 4 passes the end of the conveying roller group 311. The paper feeder mechanism 2 then responds accordingly. An alarm signal drives the first drive motor 25 to drive the two paper receiving rolls to come into contact. At this time, the paper on the two paper receiving rolls comes into contact and sticks. After the paper receiving is completed, the first drive motor 25 resets. The position detection element 5 sends a separation prompt signal when the end of the paper receiving 4 is completely separated from the conveyor roller group 311. The extension drive structure 33 resets the drive cylinder 3211 according to the separation prompt signal, and drives the hydraulic cylinder 333 to limit the connecting cylinder 324 so that it cannot rotate. The second drive motor 326 drives the threaded column 325 to rotate. Under the rotation of the threaded column 325 and the limiting action of the clamping tooth plate 334, the connecting cylinder 324 gradually moves closer to the threaded column 325, thereby gradually increasing the distance between the two conveyor roller groups 311, forming an installation channel through which the paper receiving 4 passes between the conveyor roller groups 311. The paper receiving 4 is pasted through this installation channel to one of the paper receiving rolls, waiting for the next paper receiving action.
