Problems solved by technology

However, during the loading and unloading process, the heating roller is jacked up, and all the motor connectors and bearings connected to it will be affected and dislocated. After the ring-shaped mold steel belt is replaced, it is necessary to correct the heating roller, motor connector and bearing by beating Correcting its position will cause premature wear of the corresponding parts

Embodiment 1

[0038] image 3 It shows a schematic structural view of Embodiment 1 of the multi-functional press molding compound unit provided by the present invention. The multi-functional pressing compound unit includes two sets of heating rolls and two sets of cooling rolls. Wherein, one group of heating rollers is the upper pressing type roller 11, and its temperature is set to 240~350 ℃, as the thermocompression molding heating roller of microscopic structure such as microprism. Another group of heating rollers is the lower multi-layer composite roller 12, and its temperature is set at 180~330 ℃, as the composite heating roller of multi-layer material. Two sets of heating rollers with different temperatures realize the function of setting different temperatures in different processing areas. Two groups of hydraulic rubber rollers 4 are configured for each group of heating rollers. The temperature settings of the two groups of cold rollers 2 are all kept below 18°C, so as to ensure ...

Embodiment 2

[0041] Figure 4 A schematic structural view of Embodiment 2 of the multi-functional press molding compound unit provided by the present invention is shown. The difference from Embodiment 1 lies in that the multi-functional press molding compound unit includes a set of chill rolls. Using a set of chilled rolls, the material is rapidly cooled and shaped on a set of chilled rolls, with fast cooling speed and high efficiency. It is suitable for processing soft resins such as polyvinyl chloride and polysulfone, while processing hard resins such as polymethyl methacrylate and polycarbonate is prone to residual stress and the product is easily deformed.

Embodiment 3

[0043] Figure 5 A schematic structural view of Embodiment 3 of the multi-functional press molding compound unit provided by the present invention is shown. The difference from Embodiment 1 lies in that the multi-functional molding compound unit also includes a bearing bar 5, which is arranged between two sets of heating rollers. In the process of loading and unloading the endless mold steel belt, the load-bearing rod can cooperate with the supporting parts and hydraulic lifters (not shown in the drawings) on both sides of the multi-functional molding compound unit, and the heating roller and the cold roller are pressed by the endless mold steel belt. The wrapped part is jacked up, and the old endless mold steel strip is withdrawn from the work area, and the new endless mold steel strip is moved to the work area.

Abstract

The invention relates to a multifunctional compressing composite unit and a method for manufacturing a microprism film. The unit comprises at least two groups of heating rollers and at least one group of cooling rollers; an annular die steel band surrounds the heating rollers and the cooling rollers. The method comprises: (1) mounting the annular die steel band, setting a surface temperature of the heating rollers, and setting an operation speed of the device; (2) placing at least one film in a hydraulic rubber roller of an upper compressing roller, and placing at least one film in a hydraulic rubber roller of a lower multilayered composite roller; machining and molding a microstructure by the upper compressing roller, and enabling the composite film to achieve a thickness suitable for the product by the lower multilayered composite roller; (3) cooling the annular die steel band and the film through the step (2) by the cooling rollers; and (4) separating the film which has been molded in the step (3) from the annular die steel band in the position of a peeling rubber roller, and coiling a semi-finished product. The function of setting different temperatures in different machining regions is realized, and a larger temperature difference can be set to adapt to the machining needs of different materials and functions.

Description

technical field [0001] The invention relates to a molding process of an optical film, in particular to a multi-functional molding composite unit suitable for processing and forming a microprism mold steel belt and a method for manufacturing a microprism film. Background technique [0002] The ubiquitous hot-press lamination unit for microprism products has a heating roller with a large diameter, and is equipped with five sets of hydraulic rubber rollers, and is matched with a cooling roller with a diameter similar to the heating roller. The endless mold steel belt is sheathed on the heating roller and the cooling roller, and the heating roller or the cooling roller is used as a rotating belt roller, and the mold steel belt is continuously operated by a motor or other power. Put different material films in each group of hydraulic rubber rollers. The materials are hot-pressed on the heating rollers to form a microprism structure and composite multi-layer materials. On the cool...
