[0021] The following specifically describes the specific embodiments of the utility model with reference to the accompanying drawings.

[0022] Embodiment:

[0023] The specific implementation of a casting film conveying and rectifying device of the present utility model is shown in the accompanying drawings. Refer to Figure 1 , Figure 2 , Figure 3 , which mainly includes a mounting substrate 1. Two conveying rollers 2 are spacedly mounted on the mounting substrate 1. One end of each conveying roller 2 is rotatably connected to the mounting substrate 1, and the other end is a free end.

[0024] A rectifying roller assembly 3 is provided between the two conveying rollers 2. The rectifying roller assembly 3 includes a deflecting frame 301. The deflecting frame 301 is in a U shape. A rectifying roller 302 is mounted at the bottom end of the deflecting frame 301. Both ends of the rectifying roller 302 are rotatably connected to the deflecting frame 301. The casting film a passes around the upper-level conveying roller 2, passes through the deflecting frame 301, and is guided by the rectifying roller 302 to the lower-level conveying roller 2 for conveying.

[0025] Detection wheels 303 for detecting whether the casting film a is offset are respectively provided at both ends of the rectifying roller 302. The detection wheels 303 are connected to the deflecting frame 301 through support plates 305. The detection wheels 303 are rotatably mounted at the bottom of the support plates 305. A sensor 304 for detecting whether the detection wheels 303 rotate is mounted at the top of the support plates 305. When the casting film a is offset, the detection wheel 303 at the offset end will contact the casting film a and be driven to rotate, and the sensor 304 will immediately detect the offset signal.

[0026] A connecting block 306 is provided in the middle of the top of the deflecting frame 301. Multiple connecting rods 307 are provided on the connecting block 306. One end of each connecting rod 307 is connected to the connecting block 306, and the other end is provided with a limit mounting block 308.

[0027] A driving assembly 4 is provided on the mounting substrate 1. The driving assembly 4 includes a connecting plate 401. The connecting plate 401 is connected to the top of the mounting substrate 1. A vertical plate 402 is also connected to the connecting plate 401. A high-precision rotating motor 403 is mounted on the top of the connecting plate 401. The output shaft of the high-precision rotating motor 403 passes through the vertical plate 402 and is connected to the connecting block 306 at the top of the deflecting frame 301. The high-precision rotating motor 403 can drive the deflecting frame 301 to rotate.

[0028] Multiple guide holes 402a are formed in the vertical plate 402. Multiple connecting rods 307 on the connecting block 306 respectively pass through the multiple guide holes 402a. The limit mounting block 308 is connected to one end of the connecting rod 307 passing through the guide hole 402a and is in sliding fit with the vertical plate 402. When the deflecting frame 301 rotates, the connecting rod 307 can be driven to slide in the guide hole 402a. The limit mounting block 308 is used to realize the connection between the deflecting frame 301 and the vertical plate 402.

[0029] On one side of the deflection frame 301 on the mounting substrate 1, there is also an avoidance opening 101. The avoidance opening 101 extends downward from the top surface of the mounting substrate 1. The depth of the avoidance opening 101 is greater than the height of the deflection frame 301, and the width of the avoidance opening 101 is greater than the width of the deflection frame 301. The avoidance opening 101 is used to prevent collision between the deflection frame 301 and the mounting substrate 1 when the deflection frame 301 rotates.

[0030] The utility model can correct the deviation during the conveying process of the casting film a. The deviation correcting roller 302 is arranged in the middle, which can correct the casting film a from the upper conveying roller 2 and send the corrected casting film a to the lower conveying roller 2 to achieve the accurate conveying of the casting film a. When the casting film a deviates, the detection wheel 303 at the deviation end will contact the casting film a and be driven to rotate. After the corresponding sensor 304 detects the signal, the high-precision rotating motor 403 controls the deflection frame 301 to tilt in the specified direction to counteract the generated deviation, ensuring that the casting film a can be conveyed along the specified path. That is, when the casting film a deviates towards one end away from the deviation correcting roller 302 of the mounting substrate 1, the outer detection wheel 303 contacts the casting film a and is driven to rotate by the casting film a. The outer sensor 304 immediately detects the deviation signal of the casting film a, and the high-precision rotating motor 403 controls the deflection frame 301 to rotate, causing the end of the deflection frame 301 away from the mounting substrate 1 to rise and the end close to the mounting substrate 1 to fall, driving the deviation correcting roller 302 to tilt and correct the casting film a. Similarly, if the casting film a deviates towards one end close to the deviation correcting roller 302 of the mounting substrate 1, the end of the deflection frame 301 close to the mounting substrate 1 rises and the end away from the mounting substrate 1 falls.

[0031] Of course, the above embodiments are only used to illustrate the technical concept and features of the utility model, and their purpose is to enable those who are familiar with this technology to understand the content of the utility model and implement it accordingly, and cannot be used to limit the protection scope of the utility model. All modifications made according to the spirit and essence of the main technical solution of the utility model should be covered within the protection scope of the utility model.
