If the tension on the film winding side is directly reduced, the metal or ultrathin film sags due to the unbalance of the tension between the two sides (namely the film unreeling part and the film winding part), so that the supply of the metal or ultrathin film becomes unstable, and meanwhile, the defect of the metal or ultrathin film caused by marking can be caused.
Therefore, the improvement of the above problems requires precise adjustment of the tension on both sides, but the production needs to be reset every time due to the variety and thickness of the metal or ultrathin film, and the engineering parameters such as the supply speed of the metal or ultrathin film, which is difficult to realize in real production.
The existing method is to install a nip roller on a main roller to adjust the tension between a film unreeling part and a film reeling part, thereby preventing the metal or ultra-thin film from wrinkling. However, when the clamping wheel is used, the clamping wheel may be directly clung to the metal or ultrathin film, so as to apply pressure to the metal or ultrathin film, and slight deformation of the metal or ultrathin film under pressure also increases the probability of occurrence of wrinkling and marking.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, a metallic or ultrathin film winding and coating device 100 of the present invention is used for unwinding, coating and winding a film in a vacuum state, and mainly comprises an unwinding part 110, a coating part 120 and a winding part 130. The unreeling part 110 is used for unreeling the coiled film to be coated and transmitting the film to the coating part 120 through a plurality of transmission wheels. The coating part 120 includes a main wheel, and the coating part 120 is used to cling the film provided by the unreeling part 110 to the surface of the main wheel and to coat the film surface with a coating. The winding portion 130 is used for winding the film coated with the film to a winding shaft.
In order to make the film tightly contact the main wheel as much as possible to obtain the best coating effect, a large tension is often applied to the film on the unwinding part 110, and in order to prevent the film from wrinkling during winding, the tension on the winding part 130 is reduced, so that in actual production, the tension of the unwinding part 110 needs to be 5-10 times greater than the tension of the winding part 130. However, since the tension at both ends is unbalanced, the film tends to sag, resulting in unstable transmission, and the film tends to be scratched, resulting in defects.
In order to solve the above problems, the present invention is provided with a tension adjusting device 200 at a side of the main wheel near the rear end.
Referring to fig. 2 to 6, the tension adjusting apparatus 200 includes a frame 213, a first tension adjusting wheel 210, a guide wheel 220, a second tension adjusting wheel 230, and a third tension adjusting wheel 240. The first tension adjusting wheel 210 is disposed at an end of the frame 213 near the main wheel, and the first tension adjusting wheel 210 can be tightly attached to the main wheel and rotate along with the rotation of the main wheel. The second tension adjusting wheel 230 is fixedly arranged on the frame 213 and is in transmission connection with the first tension adjusting wheel 210 through a transmission belt 211, specifically, a gear 212 is arranged on one side of the first tension adjusting wheel 210, the transmission belt 211 is sleeved on the outer peripheral side of the gear 212, and when the first tension adjusting wheel 210 rotates, the second tension adjusting wheel 230 is driven to rotate. The guide wheel 220 is fixedly arranged at one side of the frame 213 near the front end, and the third tension adjusting wheel 240 is arranged at one side of the frame 213 near the rear end.
In order to increase the friction force of the first tension adjusting wheel 210 and the second tension adjusting wheel 230 against the film, the surfaces of the first tension adjusting wheel 210 and the second tension adjusting wheel 230 are each provided with a high friction material layer, which in this embodiment is preferably polyurethane, but not limited thereto.
The first tension adjusting wheel 210 is closely attached to the surface of the main wheel, and the surface friction is high, thereby ensuring the tension of the film on the main wheel. By providing the guide wheel 220, the second tension adjusting wheel 230 and the third tension adjusting wheel 240, the tension of the film coming out of the first tension adjusting wheel 210 can be released and then transferred to the winding part 130, thereby acting to adjust the tension between the unwinding part 110 and the winding part 130.
Referring to fig. 7 to 9, in order to further adjust the tension of the film between the second tension adjusting wheel 230 and the unreeling part 110, an adjusting lever 250 is provided between the third adjusting wheel 240 and the frame 213. The adjusting lever 250 can adjust the distance between the third tension adjusting wheel 240 and the first tension adjusting wheel 210 to change the contact area of the film with the second tension adjusting wheel 230 to adjust the film tension between the second tension adjusting wheel 230 and the unreeling part 110.
The adjustment lever 250 mainly includes a lever body 253, a first end 251, a second end 252, and an adjustment block 256. Threads are formed at both ends of the adjusting rod 253, and the first end 251 and the second end 252 are respectively sleeved at both ends of the adjusting rod 253 and are in threaded connection with the adjusting rod 253. The first end 251 is connected to an end of the frame 213 near the first tension adjusting wheel 210, and the second end 252 is provided with a fixing base 241, where the fixing base 241 is connected to the third tension adjusting wheel 240. The adjusting block 256 is fixed to the outer peripheral side of the middle portion of the adjusting rod 253. Turning the adjustment block 256 may move the first end 251 and the second end 252 toward or away from each other, thereby changing the length of the adjustment lever 250, causing the distance between the third tensioning wheel 240 and the first tensioning wheel 210 to increase or decrease.
Specifically, when the adjustment block 256 is rotated in the direction 1, the first thread 253-2 of the rod 253 is withdrawn from the first end 251, and the gap 251-1 between the first end 251 and the rod 253 increases; at the same time, the second thread 253-3 of the rod 253 is withdrawn from the second end 252, and the gap 252-1 between the second end 252 and the rod 253 increases, thereby increasing the length of the adjustment rod 250. As shown in case 1 of fig. 9, the distance D2 between the first tension adjusting wheel 210 and the third tension adjusting wheel 240 increases as the length of the adjusting lever 250 increases, and the contact angle θ2 of the film with the second tension adjusting wheel 230 decreases.
When the adjustment block 256 is rotated in the direction 2, the first thread 253-2 of the rod 253 protrudes into the first end 251, and the gap 251-1 between the first end 251 and the rod 253 decreases; while the second thread 253-3 of the rod 253 is extended into the second end 252, the gap 252-1 between the second end 252 and the rod 253 is reduced, thereby shortening the length of the adjustment rod 250. As shown in case 2 of fig. 9, the distance D3 between the first tension adjusting wheel 210 and the third tension adjusting wheel 240 decreases as the length of the adjusting lever 250 decreases, and the contact angle θ3 of the film with the second tension adjusting wheel 230 increases.
The adjusting lever 250 is provided with a spring 254 and a positioning nut 255, the spring 254 is sleeved on the outer circumferential side of the rod 253, and the positioning nut 255 is in threaded connection with the rod 253 and fixes the spring 254 between the first end 251 and the positioning nut 255. By rotating the set nut 255, the spring force of the spring 254 may be increased or decreased, thereby changing the pressure of the first tensioning wheel 210 against the main wheel surface.
Referring to fig. 10, in order to prevent the belt 211 from being loosened, an auxiliary wheel 300 is provided between the first tension adjusting wheel 210 and the second tension adjusting wheel 230, and the auxiliary wheel 300 can move perpendicular to the direction of the belt 211, thereby pressing the belt 211, keeping the belt 211 tight, and securing the driving effect.
Referring to fig. 11 and 12, when the distance between the second tension adjusting wheel 230 and the winding portion 130 is long, a driving belt may be added between the second tension adjusting wheel 230 or the first tension adjusting wheel 210 and the other driving wheels 310.
While the invention has been described in conjunction with the specific embodiments above, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the foregoing description. Accordingly, all such alternatives, modifications, and variations are included within the spirit and scope of the following claims.
