The existing polarizing sheet for the vehicle-mounted instrument has different display effects at different angles, and therefore, a viewing angle compensation film is needed to be added on the basis of the existing polarizing sheet. When the polarizing sheet is produced, the existing manufacturing device has poor pressing effect on the viewing angle compensation film, and the viewing angle compensation film is easy to separate during winding. Therefore, the present application provides a manufacturing device for a polarizing sheet of a vehicle-mounted instrument. SUMMARY

[0007] a chassis;

[0008] a processing table assembly connected with the chassis;

[0009] a material collecting roller assembly connected with the processing table assembly and used for driving winding and unwinding of the film;

[0010] an elastic pressing assembly connected with the processing table assembly and used for assisting pressing of the film;

[0011] a driving adjusting device connected with the chassis;

[0012] a pressing device connected with the driving adjusting device;

[0013] wherein the pressing device comprises:

[0014] a pressing roller assembly connected with the driving adjusting device and used for cooperating with the driving adjusting device to complete pressing of the film;

[0015] A preheating assembly is connected with the pressing roller assembly and used for preheating the film.

[0016] Compared with the prior art, the device can realize the tensioning of the film during pressing, and the elastic pressing assembly and the pressing device can realize the double pressing driving of the film, thereby improving the pressing quality and stability of the film, improving the deficiencies of the existing polaroid manufacturing equipment, and having high practicability and market prospect.
