Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Example:

Referring to Fig. 1, the present invention provides a technical solution: a preparation method for continuous production of foamed silica gel sheets, comprising the following steps:

Step 1: L-shaped tablet press structure 1 adjusts different speed ratios to suppress and eliminate the air bubbles in the rubber compound;

Step 2: The lifting device 7 adjusts the position of the lower heating plate, and the pressed rubber sheet enters the upper heating plate 4 and the lower heating plate with the conveyor belt for shaping and vulcanization;

On, the calendering roller driving device and the calendering roller are connected in rotation, and the high-temperature setting and vulcanization part includes a column 2, an upper heating plate 4, a lower heating plate, a beam 3 and a base 6, the beam 3 is connected with the column 2, and the upper heating plate 4 is arranged on the beam 3. The upper and lower heating plates are connected to the lifting device 7 , and the upright column 2 and the lifting device 7 are arranged on the base 6 .

Specifically, the lifting device 7 is an oil cylinder, which has a large supporting force.

Working principle: The mechanical working principle of the present invention is that the mixed foamed rubber is re-melted by an open mill, and then the rubber is put into an L-shaped tablet press. Enter the conveyor belt and transfer it to the upper heating plate 4 and the lower heating plate for high-temperature vulcanization, so that the foamed rubber material is heated up and the rubber molecules are cross-linked. Products with certain physical and mechanical properties are obtained, but after the rubber compound is heated, it begins to liquefy, foam, and self-expand to generate pressure vulcanization. Sufficient pressure fills the mold with the compound and limits the generation of air bubbles, making the product denser. In addition, give enough pressure to prevent the overflow of the mold from the seam surface and the lack of glue in the pattern. For plate and belt products with high surface strength requirements or continuous patterns, its superiority is particularly significant, and the product performance over the entire length can be uniform.
