Abstract
Description
Technical Field
[0001] This utility model relates to the field of composite board composite devices, specifically to an unwinding mechanism for an online composite device for packaging composite boards. Background Technology
[0002] Composite panels are made of two or more substrates bonded together. The online composite device includes an unwinding mechanism, an adhesive coating mechanism, and other mechanisms. The adhesive coating mechanism is used to apply adhesive to the surface of the substrate, while the unwinding mechanism is used to release the substrate in an orderly manner.
[0003] Currently, unwinding mechanisms include a preset number of rollers. One roller holds the substrate package, while the others rotate to move the substrate forward, thus achieving unwinding. However, these unwinding mechanisms lack a tensioning mechanism, making it easy for the substrate to bend or wrinkle during its forward movement. Consequently, when the substrate reaches the gluing mechanism, the bent or wrinkled areas cannot be coated with adhesive, resulting in "empty packages" and weak adhesion during bonding, leading to a higher product defect rate. Summary of the Invention
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an unwinding mechanism for an online composite packaging board device.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: an unwinding mechanism for an online composite packaging board device, comprising: A first rotating roller, a second rotating roller, and a frame, wherein the first rotating roller and the second rotating roller are mounted on the frame and are rotatable relative to the frame; The tensioning mechanism includes a tensioning roller, a cylinder, a first support plate, a second support plate, and a support rod. The support rod is mounted on the frame. One end of the first support plate is connected to one end of the tensioning roller, and the other end of the first support plate is rotatably connected to the support rod. One end of the second support plate is connected to the other end of the tensioning roller, and the other end of the second support plate is rotatably connected to the support rod. The cylinder has a telescopic rod, which is mounted to the first support plate, thereby causing the telescopic rod to drive the tensioning roller to move.
[0006] Preferably, it further includes a first driving mechanism, which includes a first motor, a first reducer, a first rotating rod, a first sprocket, a second sprocket, and a transmission chain. The first motor is connected to the first reducer, the first rotating rod is connected to the first reducer, the first sprocket is mounted on the first rotating rod, the second sprocket is mounted on the first rotating roller, and the transmission chain connects the first sprocket and the second sprocket, thereby enabling the first motor to drive the first rotating roller to rotate.
[0007] Preferably, it further includes a second driving mechanism, which includes a second motor and a second reducer. The second motor is connected to the second reducer, and the second reducer is connected to the second rotating roller, so that the second motor drives the second reducer to rotate.
[0008] Preferably, the device further includes a position adjustment mechanism, which comprises an adjustment roller, a second cylinder, a moving block, a support frame, and a bearing. The second cylinder has a second telescopic rod, which is mounted together with the moving block to drive the moving block to move. The bearing is mounted on the moving block and is mounted together with the adjustment roller, so that the adjustment roller can rotate relative to the moving block. The support frame has a sliding groove, the moving block is mounted in the sliding groove, and the moving block can slide in the sliding groove. The adjustment roller is located above the second rotating roller.
[0009] Preferably, the tensioning mechanism further includes a tension sensor assembly, which includes a tension sensor body and a cover. The tension sensor body is mounted on the frame, and the cover is fitted onto the tension sensor body to protect it.
[0010] Preferably, the tension sensor assembly further includes a swing arm structure, the swing arm structure including a missing gear and a toothed plate, the toothed plate being mounted on the first support plate, the toothed plate being provided with a toothed structure in the form of an arc segment; the missing gear being mounted on the tension sensor body, the missing gear meshing with the toothed structure of the toothed plate.
[0011] The beneficial effects of this application are as follows: The unwinding mechanism of the online laminating device for packaging composite sheets provided by this application has the advantages of simple structure and easy assembly. Given the presence of a first driving mechanism and a second driving mechanism, the first driving mechanism can drive the first rotating roller to rotate, and the second driving mechanism can drive the second rotating roller to rotate. The combined action of the two rotating rollers makes the movement of the substrate more powerful. Secondly, given the presence of a position adjustment mechanism, the gap between the second rotating roller and the adjustment roller can be adjusted, thus adapting to substrates of different thicknesses. Furthermore, given the presence of a tensioning mechanism, the tensioning mechanism changes the tension when the tensioning roller contacts the substrate by moving the tensioning roller to a preset position. The tensioning mechanism is also equipped with a tension sensor assembly, which can monitor the tension between the tensioning roller and the substrate. Compared to the prior art, this application adjusts the tension of the substrate by setting a tensioning mechanism, thereby eliminating substrate bending and wrinkles, and improving product yield.

[0019] Please refer to Figure 1-4 This application provides an unwinding mechanism (hereinafter referred to as "the unwinding mechanism") for an online laminating device for packaging composite sheets, the unwinding mechanism comprising: A first rotating roller 11, a second rotating roller 21, and a frame 5 are provided. The first rotating roller 11 and the second rotating roller 21 are mounted on the frame 5 and are rotatable relative to the frame 5. Tensioning mechanism 4 includes a tensioning roller 41, a cylinder 42, a first support plate 44, a second support plate 45, and a support rod 46. The support rod 46 is mounted on the frame 5. One end of the first support plate 44 is connected to one end of the tensioning roller 41, and the other end of the first support plate 44 is rotatably connected to the support rod 46. One end of the second support plate 45 is connected to the other end of the tensioning roller 41, and the other end of the second support plate 45 is rotatably connected to the support rod 46. The cylinder 42 has a telescopic rod 420, which is mounted on the first support plate 44, thereby causing the telescopic rod 420 to drive the tensioning roller 41 to move. In this way, when the tensioning roller 41 moves to a preset position, it can lift the moving substrate, thereby making the substrate taut and preventing the substrate from bending or wrinkling, thus improving the product yield. During rotation, the first rotating roller 11 and the second rotating roller 21 force the substrate to move forward continuously. The rotation of the first rotating roller 11 and the second rotating roller 21 can be driven manually or by a mechanical device. Preferably, in this application, the rotation of the first rotating roller 11 and the second rotating roller 21 is achieved by a mechanical device.
[0020] Please refer to some embodiments of this application. Figure 1-4The unwinding mechanism further includes a first drive mechanism 1, which comprises a first motor 12, a first reducer 13, a first rotating rod 14, a first sprocket 15, a second sprocket 16, and a transmission chain 17. The first motor 12 is connected to the first reducer 13, the first rotating rod 14 is connected to the first reducer 13, the first sprocket 15 is mounted on the first rotating rod 14, the second sprocket 16 is mounted on the first rotating roller 11, and the transmission chain 17 connects the first sprocket 15 and the second sprocket 16, thereby enabling the first motor 12 to drive the first rotating roller 11 to rotate. Those skilled in the art should understand that the reducer 13 is a common mechanical device whose main purpose is to convert the high speed of the first motor 12 to a low speed. In this application, the reducer 13 is a worm gear reducer.
[0021] Please refer to some embodiments of this application. Figure 1-4 The unwinding mechanism further includes a second drive mechanism 2, which includes a second motor 22 and a second reducer 23. The second motor 22 is connected to the second reducer 33, and the second reducer 33 is connected to the second rotating roller 21, thereby causing the second motor 22 to drive the second reducer 33 to rotate. In this application, the first rotating roller 11 and the second rotating roller 21 are spaced apart; for example, the second rotating roller 21 is located above the first rotating roller 11. As mentioned above, the second reducer 23 is also a common mechanical device used to lower the second motor 22. In this application, preferably, the second reducer 23 is a worm gear reducer.
[0022] Please refer to some embodiments of this application. Figure 1-4The unwinding mechanism also includes a position adjustment mechanism 3, which comprises an adjusting roller 31, a second cylinder 32, a moving block 34, a support frame 33, and a bearing 35. The second cylinder 32 has a second telescopic rod 320, which is mounted together with the moving block 34 to drive the moving block 34 to move. The bearing 35 is mounted on the moving block 34 and is mounted together with the adjusting roller 31, allowing the adjusting roller 31 to rotate relative to the moving block 34. The support frame 33 has a sliding groove 330, into which the moving block 34 is mounted and can slide. The adjusting roller 31 is located above the second rotating roller 21. Thus, the second cylinder 32 drives the moving block 34 to move within the sliding groove 330 of the support frame 33, causing the adjusting roller 31 to move closer to or further away from the second rotating roller 21, adjusting the gap between the adjusting roller 31 and the second rotating roller 21 according to the thickness of the substrate. In this application, there can be multiple second cylinders 32, moving blocks 34, support frames 33, and bearings 35. For example, in this application, there are two second cylinders 32, moving blocks 34, support frames 33, and bearings 35. The components consisting of second cylinders 32, moving blocks 34, support frames 33, and bearings 35 are respectively arranged at both ends of the adjusting roller 31, thereby realizing the adjustment of the gap between the adjusting roller 31 and the second rotating roller 21.
[0023] Please refer to some embodiments of this application. Figure 1-4 The tensioning mechanism 4 further includes a tension sensor assembly 43, which includes a tension sensor body 432 and a cover 431. The tension sensor body 432 is mounted on the frame 5, and the cover 431 is fitted onto the tension sensor body 432 to protect it. In this application, the tension sensor body 432 is used to monitor the tension on the tension roller 41.
[0024] Please refer to some embodiments of this application. Figure 1-4The tension sensor assembly 43 further includes a swing arm structure, which includes a broken gear 433 and a toothed plate 434. The toothed plate 434 is mounted on the first support plate 44 and has a toothed structure 4340 with an arc segment. The broken gear 433 is mounted on the tension sensor body 432, and the broken gear 433 meshes with the toothed structure 4340 of the toothed plate 434. Thus, when the cylinder 42 drives the telescopic rod 420 to a preset position, the telescopic rod 420 also moves the first support plate 44 to the preset position. During the movement of the first support plate 44, the toothed plate 434 moves, causing the toothed structure 4340 to rotate relative to the broken gear 433 by a preset angle. When the adjusting roller 41 reaches the preset position, tension is applied to the adjusting roller 41, and the geared structure 4340 will also tightly abut against the broken gear 433, thereby enabling the tension sensor body 432, which is mounted with the broken gear 433, to monitor the tension.

It features a first driving mechanism and a second driving mechanism. The first driving mechanism drives the first rotating roller to rotate, and the second driving mechanism drives the second rotating roller to rotate. The combined action of the two rotating rollers makes the movement of the substrate more powerful. Secondly, it includes a position adjustment mechanism that can adjust the gap between the second rotating roller and the adjustment roller, thus adapting to substrates of different thicknesses. Furthermore, it includes a tensioning mechanism that changes the tension between the tensioning roller and the substrate by moving the tensioning roller to a preset position. The tensioning mechanism also includes a tension sensor assembly that can monitor the tension between the tensioning roller and the substrate. Compared to existing technologies, this application adjusts the tension of the substrate by incorporating a tensioning mechanism, thereby eliminating substrate bending and wrinkles, and improving product yield.
