Description

Technical Field

[0001] This invention relates to the technical field of optical thin film production, specifically to an optical thin film conveying mechanism. Background Technology

[0002] In the production and processing of optical thin films, winding and conveying is a crucial step. As a high-precision material, the flatness of the surface, the neatness of the edges, and the tightness after winding directly affect the quality and performance of the final product. Although traditional optical thin film winding equipment can complete the basic winding task, it is often difficult to avoid the optical film being affected by external forces and other factors during the winding and conveying process, which is not conducive to flattening the film and makes it difficult to carry out subsequent conveying and winding operations, thus reducing the practicality of the overall equipment.

[0003] Therefore, based on the above problems, the present invention provides an optical thin film delivery mechanism. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an optical thin film delivery mechanism that solves the problems mentioned in the background art.

[0017] 1. This invention, through the cooperative arrangement of conveying components and other structures, drives the motor to rotate the lower conveyor roller shaft, which in turn drives the lower conveyor roller to rotate synchronously via the lower conveyor belt. Simultaneously, under the meshing operation, it synchronously drives the upper conveyor belt to rotate. At the same time, since the front end of the lower conveyor roller shaft on the left is connected to the connecting shaft via a synchronous pulley and synchronous belt, the power is transmitted to the linkage roller, which tensions the conveying components and drives the connecting roller and the conveyor roller to rotate synchronously, thereby realizing the conveying of the film body from left to right.

[0018] 2. This invention, through the setting of the tensioning conveyor fitting component, ensures that when the optical film is conveyed from left to right, it passes through the tensioning conveyor fitting component. Relying on the gravity drive of the counterweight, the belt is always kept at the preset tension, avoiding slippage or power loss caused by belt slack. It ensures the synchronous transmission accuracy of the drive belt, connecting shaft, and fitting shaft, eliminating the need for frequent manual adjustments. The mechanical structure automatically compensates for belt deformation, reducing maintenance costs. It is suitable for continuous conveying scenarios and facilitates the tensioning and flattening of the optical film during the conveying process, which is beneficial for conveying operations.
