[0002] The polyimide film is a kind of film insulation material, which needs to be coated with a layer of coating on the surface of the film and then dried during the processing. During the film drying process, the film belt is continuously fed into the drying oven from the inlet of the drying oven, and then is taken out from the outlet of the drying oven after drying, and is then pulled by the film conveying device and wound by the winding device. Only a general roller conveyor is provided between the outlet end and the winding device to convey the belt. These conveying rollers are usually fixed or slightly displaceable forward and backward. However, since the drying space in the general drying oven is relatively long, usually tens of meters, the belt may be slightly deformed during drying in the drying oven due to the long drying time, resulting in a relatively loose belt. Moreover, since the belt is dried as a whole in the drying oven, the deformation area cannot be predicted, and thus the deformation areas on both sides of the belt are inconsistent, and the loosening degree of the local areas on both sides of the belt is different, resulting in local wrinkles during winding. Therefore, it is necessary to provide a device that can freely adjust the loosening degree of the belt caused by different deformations on both sides of the belt before winding. SUMMARY

[0022] The technical solutions in the utility model will be further explained in connection with the drawings and embodiments.

[0023] As Figures 1 to 6 shown in the utility model embodiment, a film conveying belt capable of correcting deviation is provided, which comprises a roller conveying belt 1, the roller conveying belt 1 comprises two side plates 11 arranged oppositely and a plurality of rollers connected to the inner side of the side plates 11, spaces are further arranged between the rollers, the roller conveying belt 1 is sequentially provided with a detection assembly 2 and an adjusting assembly 3 along the conveying direction, the detection assembly 2 and the adjusting assembly 3 are arranged between the rollers, the detection assembly 2 comprises a mounting frame 21 suspended above the conveying belt, a plurality of sensors 22 are further arranged on the lower surface of the mounting frame 21, the detection range of the sensors 22 can cover the conveying width of the conveying belt, the adjusting assembly 3 comprises an electric telescopic cylinder 31 fixedly installed on the outer side of the side plate 11, a connecting seat 32 fixedly connected to the telescopic end of the electric telescopic cylinder 31, and a rotating seat 34 connected to the top of the connecting seat 32, further comprising an adjusting roller 35 connected to the rotating seats 34, the rotating seat 34 can further slide on the top of the connecting seat 32, the sliding direction is perpendicular to the telescopic direction of the electric telescopic cylinder 31, the rotating axis of the rotating seat 34 is perpendicular to the conveying direction, and the end of the adjusting roller 35 is connected to one side of the rotating seat 34 through a bearing.

[0024] The problem of local wrinkles in the film after deformation and winding is solved by arranging the detection assembly 2 and the adjusting assembly 3 between the general roller type film conveying belt. When the film comes out of the discharge port after long-time baking in the baking oven and is then pulled by the conveying belt, the film is detected by the sensor 22 due to the side relaxation or deformation phenomenon of different degrees in the two sides or partial areas of the film caused by baking when the film is conveyed on the roller. Then the data is transmitted to the device for processing and calculation, and then the extension end of the electric telescopic cylinder 31 is moved according to the requirement, thereby driving the connecting seat 32 to move. At this time, the rotating seat 34 at the top of the connecting seat 32 also follows the displacement, and the adjusting roller 35 connected to one end of the rotating seat 34 also follows the position adjustment. Since the rotating seat 34 is slidingly arranged and rotates at the top of the connecting seat 32, the rigidity of the adjusting roller 35 naturally drives the rotating seat 34 to slide at the top of the connecting seat 32, and the rotating seat 34 also rotates to adapt to the position of the adjusting roller 35, preventing mutual interference. After the displacement of one end of the adjusting roller 35 is adjusted, the inconsistent relaxation of the film can be adapted, and at the same time, the detection assembly 2 continuously detects the relaxation of the film, and the electric telescopic cylinder 31 drives the adjusting roller 35 to adjust the position in real time according to different tightness requirements, so that the winding device can reduce the phenomenon of wrinkles as much as possible during winding.

[0025] Further, as shown in Figure 6 , the two ends of the mounting frame are fixedly connected to the top of the side plate 11, the sensor 22 is a contact sensor, a plurality of the sensor 22 is distributed along a straight line and perpendicular to the conveying direction, and the bottom contact point of the sensor 22 is an arc contact point. When the film is relatively tight, the bottom of the contact sensor can contact the upper surface of the film, and when the film is in a relaxed state, the arc-shaped bottom of the contact sensor cannot contact the film. In order to increase the detection accuracy and prevent the problem that the film itself is relaxed but wrinkles, the convex wrinkle part contacts the sensor 22, and then the sensor 22 sends an error signal.

[0026] Further, as shown in Figure 4 , the two sides of the cylinder body front end of the electric telescopic cylinder 31 further extend and are fixedly connected with the sliding rails 311, and the connecting seat 32 is slidingly arranged on the sliding rails 311. Through the sliding rails 311, the displacement of the connecting seat 32 is more stable, and the accuracy of the entire adjusting assembly 3 is increased.

[0028] Further, as shown in the figure, Figure 4 The top of the connecting seat 32 is provided with a sliding groove 321 and a sliding block 33 corresponding to the sliding groove 321, the sliding direction of the sliding groove 321 is perpendicular to the telescopic direction of the electric telescopic cylinder 31, the sliding groove 321 is preset so that the rotating seat 34 can slide in the sliding groove 321, and the problem that the adjusting roller interferes with the displacement of the connecting seat 32 when the rotating seat 34 is displaced by the connecting seat 32 is prevented, the rotating seat 34 includes an L-shaped bottom plate 342 and a vertical plate 341, the bottom plate 342 is connected to the top of the sliding block 33, and the end of the adjusting roller 35 penetrates the vertical plate 341 and is connected to the preset bearing hole 343 through a bearing; as shown in the figure, Figure 4 and 5 The bottom of the sliding block 33 can be rectangular, the sliding groove 321 is also set to correspond to the rectangle, the bottom of the sliding block 33 is slidably connected with the sliding groove 321, and the top can be circular, and bearings can be arranged around the top edge, the top of the sliding block 33 provided with the bearings is connected to the bottom of the bottom plate 342 provided with a ring-shaped hole in advance, so that the sliding block 33 drives the rotating seat 34 to displace in the sliding groove 321 of the connecting seat 32, and the rotating seat 34 can also rotate.

[0029] Further, as shown in the figure, Figure 2 The adjusting roller 35 is provided with a protruding thread 351, the thread 351 extends to the end from the middle position of the adjusting roller 35, the protruding top of the thread 351 is arc-shaped, through the above-mentioned structure, the wrinkled film can be smoothed, and the arc-shaped top of the thread 351 will not damage the film.
