[0031] Please see Figure 1As shown in the figure, this application embodiment provides a roll splicing device 100 for splicing new and old rolls of material, where the rolls can be prepreg (PP), film, or other fabrics. The roll splicing device 100 includes: a machine base 1, a feeding mechanism 2, a conveying mechanism 3, and a splicing mechanism 4. The feeding mechanism 2 is mounted on the machine base 1 and is used to place rolls of material (e.g., a first roll 200 and a second roll 300). The conveying mechanism 3 is mounted on the machine base 1 and arranged side-by-side with the feeding mechanism 2. A conveying path a is formed between the conveying mechanism 3 and the feeding mechanism 2. The rolls on the feeding mechanism 2 are conveyed along the conveying path a, bypassing the conveying mechanism 3, and further conveyed to subsequent production lines via the conveying mechanism 3. The splicing mechanism 4 is mounted on the machine base 1 and located between the feeding mechanism 2 and the conveying mechanism 3. The splicing mechanism 4 is located below the conveying path a. The splicing mechanism 4 includes a splicing platform 41, through which a plurality of adsorption holes 42 are provided. The adsorption holes 42 are used to communicate with a vacuum device (not shown in the figure). The splicing platform 41 is used to adsorb the roll material. That is, under the negative pressure provided by the vacuum device, the roll material 200 is adsorbed on the splicing platform 41, which can effectively reduce the occurrence of phenomena such as curling and warping of the joints during the splicing process and improve the splicing flatness.
[0032] Please refer to it again. Figure 1 As shown, the machine tool 1 includes a frame 11, which includes two opposing side walls 12 forming a conveying space. The feeding mechanism 2, the transmission mechanism 3, and the splicing mechanism 4 are all located in the conveying space and mounted on the side walls 12. The machine tool 1 also includes a drive module 13 located outside the side walls 12, which drives the operation of the transmission mechanism 3.
[0033] In some embodiments, a storage structure 14 is provided on the outer side of the sidewall 12, the drive module 13 is disposed in the storage structure 14, and the storage structure 14 is provided with a door 15 to facilitate maintenance of the drive module 13.
[0034] Please see Figure 2 and Figure 3 As shown, please refer to the following: Figure 1 As shown, the feeding mechanism 2 includes a first support structure 21 and a second support structure 22 arranged opposite to each other along a direction perpendicular to the conveying path a, with the two ends of the roll material placed on the first support structure 21 and the second support structure 22 respectively.
[0035] In some embodiments, the feeding mechanism 2 further includes a first feeding component 23, which is used to feed the first roll 200. Specifically, the first feeding component 23 includes a first feeding part 231 and a first limiting part 232 disposed on the first support structure 21, and a second feeding part 233 and a second limiting part 234 disposed on the second support structure 22, wherein the first feeding part 231 and the second feeding part 233 are disposed opposite to each other. The two ends of the first roll 200 are respectively disposed on the first feeding part 231 and the second feeding part 233, and are limited by the first limiting part 232 and the second limiting part 234. Specifically, the first roll 200 located on the first feeding component 23 is wound around the transmission mechanism 3 via the transmission path a, and further enters the subsequent production line.
[0036] In some embodiments, the feeding mechanism 2 further includes a second feeding assembly 24, which is used to feed the second roll 300. The second feeding assembly 24 includes a third feeding section 241 disposed on the first support structure 21 and a fourth feeding section 242 disposed on the second support structure 22, wherein the third feeding section 241 and the fourth feeding section 242 are disposed opposite to each other. The second feeding assembly 24 is mainly used as a temporary storage for the second roll 300, with both ends of the second roll 300 disposed on the third feeding section 241 and the fourth feeding section 242, respectively. When it is necessary to replace the first roll 200, the first roll 200 is removed from the first feeding assembly 23, and then the second roll 300 is moved from the second feeding assembly 24 to the first feeding assembly 23.
[0037] In some embodiments, the first feeding assembly 23 and the second feeding assembly 24 are connected by a slide rail. Specifically, the first feeding section 231 and the third feeding section 241 are connected by a first slide rail 25, and the second feeding section 233 and the fourth feeding section 242 are connected by a second slide rail 26, so as to move the second roll 300 located on the second feeding assembly 24 to the first feeding assembly 23.
[0038] Please refer to it again. Figure 1 As shown, the transmission mechanism 3 includes multiple guide rollers 31 arranged sequentially along the transmission path a. The first roll 200 is wound on the multiple guide rollers 31, and the multiple guide rollers 31 are used to limit and guide the first roll 200.
[0039] Please see Figures 4 to 6 As shown, please refer to the following: Figure 1As shown, the splicing mechanism 4 also includes an adsorption structure 43 disposed on the machine base 1, and the splicing platform 41 is disposed on the adsorption structure 43. The adsorption structure 43 has a cavity 44, and the adsorption holes 42 communicate with the cavity 44. The cavity 44 is used to communicate with the vacuum device. Through the adsorption structure 43 with the cavity 44, on the one hand, the presence of the cavity 44 can make the adsorption force of the multiple adsorption holes 42 more uniform, improve the uniform adsorption of the first roll material 200, further improve the adsorption stability of the first roll material 200, and further reduce phenomena such as joint curling and warping during splicing. At the same time, it can also provide support for splicing and further improve the splicing strength.
[0040] In some embodiments, the splicing platform 41 includes a splicing surface 45 facing the conveying path a, and the adsorption hole 42 is disposed through the splicing surface 45. Since the conveying path a changes as the diameter of the first roll 200 decreases, when the first roll 200 needs to be replaced, the splicing surface 45 is parallel to the conveying path a. In this way, the first roll 200 located on the conveying path a can be more easily adsorbed onto the splicing surface 45, increasing the adsorption area between the splicing surface 45 and the first roll 200, and further improving the adsorption stability.
[0041] In some embodiments, multiple adsorption holes 42 are evenly distributed on the splicing platform 41, which can further adsorb the first roll 200 evenly onto the splicing surface 45.
[0042] In some embodiments, the splicing platform 41 further includes a bent portion 46 connected to the splicing surface 45. The bent portion 46 extends in a direction away from the conveying path a, and forms an obtuse angle α between the bent portion 46 and the splicing surface 45, or the bent portion 46 forms an acute angle with the conveying path a. By providing a downwardly extending bent portion 46 on the edge of the splicing platform 41 near the conveying mechanism 3, damage to the first roll material 200 by the edge of the splicing platform 41 can be reduced after the splicing platform 41 adsorbs the first roll material 200, while the bent portion 46 can also provide support for the first roll material 200.
[0043] Please refer to it again. Figure 1As shown, the roll splicing device 100 further includes a positioning mechanism 5 disposed between the splicing mechanism 4 and the transmission mechanism 3. The positioning mechanism 5 includes two connecting arms 51 and a positioning rod 52. The two connecting arms 51 are rotatably connected to the machine base 1, and the two ends of the positioning rod 52 are respectively rotatably connected to the two connecting arms 51. When the first roll 200 is located on the transmission path a, the positioning rod 52 is located above the first roll 200, and the positioning rod 52 can rotate along a preset path b to position the first roll 200, thereby improving the transmission stability of the first roll 200. At the same time, it can also allow the first roll 200 to approach or adhere to the splicing mechanism 4, so that the splicing mechanism 4 can better adsorb the first roll 200. When the first roll 200 needs to be positioned, the connecting arm 51 drives the positioning rod 52 to rotate, so that the positioning rod 52 and the splicing surface 45 of the splicing platform 41 are roughly on the same plane, so that the first roll 200 is close to the splicing surface 45; or, the connecting arm 51 drives the positioning rod 52 to rotate, so that the positioning rod 52 is lower than the plane where the splicing surface 45 is located, so that the first roll 200 can be pressed onto the splicing surface 45, further improving the splicing stability.
[0044] In some embodiments, the positioning mechanism 5 further includes a limiting post 53 disposed on the machine base 1, and the connecting arm 51 is located above the limiting post 53. When the connecting arm 51 drives the positioning rod 52 to rotate close to the splicing mechanism 4, the connecting arm 51 abuts against the limiting post 53, thereby achieving the function of limiting the movement of the positioning rod 52.
[0045] Please see Figures 7 to 9 As shown, please refer to the following: Figure 1 The process of splicing roll materials using the roll splicing device 100 specifically includes the following steps:
[0046] First step, such as Figure 7 As shown, the first roll 200 located on the first feeding assembly 23 is wound onto the guide roller 31 of the transmission mechanism 3 via the conveying path a, and the positioning mechanism 5 is rotated. During the rotation, the positioning rod 52 presses down the first roll 200 located on the conveying path a and brings it close to the splicing platform 41. At the same time, the second roll 300 can be temporarily placed on the second feeding assembly 24 for storage.
[0047] The second step, as Figure 8 As shown, when the first roll 200 needs to be replaced, the first roll 200 is placed close to the splicing surface 45 of the splicing platform 41, and the vacuum device is turned on to provide negative pressure to the splicing mechanism 4, so that the first roll 200 is adsorbed on the splicing surface 45 and the bending part 46.
[0048] The third step, as Figure 9As shown, the first roll 200 is cut off from the spool on which the first roll 200 is wound, either manually or by an automatic cutting method, and the spool and the remaining first roll 200 are removed from the first feeding assembly 23.
[0049] Step four, as Figure 9 As shown, the second roll 300 located on the second feeding assembly 24 is moved to the first feeding assembly 23, and the end of the second roll 300 is pulled to bond the end of the second roll 300 to the surface of the first roll 200 located on the splicing surface 45 through an adhesive layer, thereby achieving splicing of the first roll 200 and the second roll 300. Afterwards, the vacuum device is turned off, the negative pressure on the splicing mechanism 4 disappears, the adsorption on the first roll 200 is released, and subsequent feeding can proceed.
[0050] The roll splicing device 100 provided in this application embodiment, by setting a splicing mechanism 4 with adsorption function between the feeding mechanism 2 and the conveying mechanism 3, can adsorb and fix the old roll (i.e., the first roll 200) onto the splicing platform 41, improving the stability of the roll during the splicing process, facilitating the splicing and fixing of the new roll (i.e., the second roll 300) with the old roll, effectively reducing phenomena such as curling and warping at the joints during the splicing process, and also providing support for the splicing, improving the splicing strength. Using the aforementioned roll splicing device 100 to splice new and old rolls is convenient to operate, has high splicing efficiency, and can be completed by one person, reducing manual labor.
[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application.
