Moreover, the film flattening device flattens the film 150 by means of traction force to two sides of the film 150, the flattening uniformity is high, and the adverse situation that the transverse uniformity is poor in the flattening process of the arc roller is well improved. In addition, in the flattening process of the film 150, the flattening module can be arranged at any position in the width direction of the film 150, the mounting position is flexible, and the requirements on the layout of a factory building are low. In addition, the film 150 flattening device is simple in structure, the scheme is easy to realize, and the flattening device has important significance for flattening treatment in the production process of the battery diaphragm.

With continued reference to fig. 3 and 4, in this embodiment, the flattening modules are disposed in pairs, and in particular, the flattening modules may be symmetrically disposed on both sides of the film 150 in the width direction. By the arrangement, the film 150 is subjected to symmetrical traction force F in the film running process, so that the consistency of the film 150 in the transverse direction is further ensured, and the working reliability of the film flattening device in the embodiment is improved.
It should be noted that, in this embodiment, a plurality of pairs of flattening modules may be disposed according to the longitudinal length of the film 150, so as to further ensure the flattening reliability of the film 150.
With continued reference to fig. 1-4, in this embodiment, the edge clamping device includes an upper pressing roller 100 and a lower pressing roller 110 for clamping the film 150, where the upper pressing roller 100 and the lower pressing roller 110 are disposed parallel to each other.

In the flattening process of the film 150, the upper press roll 100 and the lower press roll 110 clamp the film 150, so that the film 150 is subjected to a traction force F perpendicular to the axes of the upper press roll 100 and the lower press roll 110, and the film 150 is flattened under the action of the traction forces F at two sides of the width direction of the film 150. The pivoting arrangement of the upper press roller 100 and the lower press roller 110 greatly reduces the friction force in the contact process of the film 150 with the upper press roller 100 and the lower press roller 110, thereby reducing the damage to the film surface and further improving the working reliability of the film flattening device of the embodiment.
In addition, by adjusting the relative angle between the lower roll base 70 and the film 150, the direction of the traction force F can be controlled, so as to ensure the flattening effect of the film 150 to the maximum extent.

In this embodiment, the threaded hole may be one, and the fixing screw 140 is matched with the threaded hole. In order to ensure the stability of the support 20 after the limit, a plurality of threaded holes and a plurality of fixing screws 140 matched with the threaded holes can be provided, so long as the fixing of the support 20 after the transverse position adjustment can be realized.
With continued reference to fig. 1-4, in this embodiment, the lower roller seat 70 is rotatably connected to the support 20 by a pin 30, wherein the axis of the pin 30 is vertical. And, a stopper for restricting the rotated position of the lower roll stand 70 is further provided on the stand 20.
Referring to fig. 1-4, in the present embodiment, the support 20 includes opposite sides, the limiting member includes limiting screws 120 disposed on each side, and each limiting screw 120 is screwed on the side and abuts against the lower roller seat 70 to limit the rotated position of the lower roller seat 70.

Specifically, in the present embodiment, the upper surface of the support 20 is provided with a groove, the lower roll seat 70 is in an "L" shape, the horizontal edge of the "L" lower roll seat 70 is disposed in the groove, and the width of the groove is greater than the width of the horizontal edge, so as to provide enough space for the rotation of the lower roll seat 70.
When the included angle between the axis of the lower press roller 110 and the film running direction needs to be adjusted, the limit screw 120 is unscrewed, then the lower press roller seat 70 rotates around the pin 30, after the lower press roller seat 70 rotates to a required position, the limit screws 120 on two sides of the support 20 are screwed to tightly support the lower press roller seat 70, and the position of the lower press roller seat 70 can be fixed under the auxiliary action of the pin 30.
With continued reference to fig. 2, in this embodiment, a lock nut 130 may be disposed on each of the limit screws 120. Specifically, the lock nut 130 is screwed on the limit screw 120 and abuts against a side edge of the support 20. After limiting the lower roll seat 70 by the limiting screw 120, the locking nut 130 can be screwed to reduce the adverse condition of shaking of the lower roll seat 70 caused by loosening of the limiting screw 120.
With continued reference to fig. 1-3, in this embodiment, the film flattening device may further include an upper roller stand 80. Specifically, the upper press roll seat 80 is slidably mounted on the lower press roll seat 70, and the sliding direction is vertical, and the upper press roll 100 is pivotally connected to the upper press roll seat 80.
Specifically, in this embodiment, a guiding device 90 for guiding in a sliding manner may be disposed between the upper press roll seat 80 and the lower press roll seat 70, where the guiding device 90 includes a linear guide rail and a slider slidingly connected with the linear guide rail, the linear guide rail is fixedly connected with a side wall of the lower press roll seat 70, the slider is fixedly connected with a side wall of the upper press roll seat 80, and the upper press roll seat 80 and the lower press roll seat 70 can slide relatively in a vertical direction by using sliding fit between the slider and the linear guide rail.
In the present embodiment, the guide device 90 may be a structure in which the linear guide rail is fixedly connected to the lower roll stand 70 and the slider is fixedly connected to the upper roll stand 80, but not limited thereto, and may be other structures, for example, a structure in which the linear guide rail is fixedly arranged on the upper roll stand 80 and the slider is fixedly arranged on the lower roll stand 70, and the sliding connection and guiding between the upper roll stand 80 and the lower roll stand 70 may be realized by arranging the guide device 90.
With continued reference to fig. 1-4, in this embodiment, the film flattening device may further include a pre-tightening device for adjusting the pressing force between the upper pressing roller 100 and the lower pressing roller 110. Specifically, the pre-tightening device comprises a tension spring 40 and an adjusting component for adjusting the elongation of the tension spring 40, wherein the tension spring 40 is arranged between the upper press roller seat 80 and the lower press roller seat 70, one end of the tension spring is fixedly connected with the lower press roller seat 70, and the other end of the tension spring is movably connected with the upper press roller seat 80 through the adjusting component.
Specifically, the adjusting assembly may include an adjusting lever 50 and an adjusting nut 60, wherein the adjusting lever 50 includes a screw portion 51 and a hanger portion 52 for connecting with the tension spring 40, and the screw portion 51 passes through the upper roll seat 80 from bottom to top and is screwed into the adjusting nut 60, so that the adjusting nut 60 is closely abutted with the upper surface of the upper roll seat 80.
When the pressing force between the upper press roller 100 and the lower press roller 110 needs to be adjusted, the adjusting nut 60 may be rotated, and the rotation of the adjusting nut 60 is converted into the vertical feeding of the screw portion 51 by using the screw transmission relationship between the screw portion 51 and the adjusting nut 60, thereby elongating the tension spring 40. At this time, the tension spring 40 has an elastic restoring force. According to hooke's law, the magnitude of the elastic restoring force is proportional to the elongation, so that the larger the elongation of the tension spring 40, the larger the elastic restoring force, and the larger the pressing force between the upper press roller 100 and the lower press roller 110. With this feature of the tension spring 40, the pretension adjustment between the upper platen roller 100 and the lower platen roller 110 can be achieved.
In this embodiment, the upper press roller 100 always maintains contact with the lower press roller 110 under the action of its own weight, so as to press the film 150. "tension spring" means that the spring is always in tension and the film 150 is subjected to the combined action of the gravity of the upper press roller 100 and the elastic restoring force of the tension spring 40 during the flattening process. When the tension spring 40 continues to be stretched, the upper press roller 100 remains in contact with the lower press roller 110, and the elastic restoring force increases with the increase of the elongation, so that the adjustment of the pressing force between the upper press roller 100 and the lower press roller 110 is realized.
Through setting up preloading device, realized the regulation to film 150 clamp force for operating personnel can select suitable clamp force according to film 150 characteristic, in order to fully guarantee the exhibition paper-back edition effect.
In this embodiment, the adjusting rod 50 may be a sheep eye screw.
It should be noted that, in the present embodiment, the pretensioning device may be in the form of the tension spring 40, but is not limited thereto, and may take other forms, such as the cylinder 160. Specifically, as shown in fig. 5, the cylinder body of the cylinder 160 is fixedly connected with the lower roll stand 70, and the piston rod is fixedly connected with the upper roll stand 80.
By providing the air cylinder 160 between the upper roll stand 80 and the lower roll stand 70, not only can the adjustment of the pressing force between the upper roll 100 and the lower roll 110 be achieved by the extension and retraction of the piston rod, but also the upper roll 100 can be lifted up to separate the upper roll 100 from the lower roll 110 for maintenance. Moreover, the power source of the air cylinder 160 is air, which is widely available and clean, and basically does not pollute the film 150.
In addition, in the present embodiment, a connection member 170 may be further provided between the piston rod of the air cylinder 160 and the upper roll base 80. The connection member 170 plays a role of conversion connection, and is convenient for assembly, so that the power of the air cylinder 160 can be smoothly transferred to the upper press roller 100.
The flattening process of the film flattening device is that, as shown in fig. 4, first, the lower roll seat 70 on two sides of the width direction of the film 150 is adjusted to rotate a certain angle by taking the pin 30 as the center, then the limit screw 120 on the support 20 is screwed to enable the free end of the limit screw to abut against the lower roll seat 70, the lock nut 130 is screwed to enable the free end of the limit screw to abut against the side edge of the support 20, at this time, the included angle between the axis of the upper roll 100 and the film running direction is alpha, meanwhile, the position of the upper end of the lower roll seat 70 in the width direction of the film 150 can be adjusted by using the fixing screw 140, and then the pressing force between the upper roll 100 and the lower roll 110 can be adjusted by using the pre-tightening device. In the film running process of the film 150, both sides in the width direction are subjected to traction forces F perpendicular to the axes of the pressing rollers, so that the film 150 is pulled to both sides, and wrinkles generated by the film 150 under the action of longitudinal tensile stress are weakened or eliminated, so that the flattening purpose is realized.
