Roller press mechanism for external protection layer sheet production

Abstract

The invention relates to a roller press mechanism for external protection layer sheet production. The roller press mechanism comprises a base, wherein a first reversing rotary shaft, a first reversing mechanism, a first laminating mechanism, a second reversing mechanism, a second laminating mechanism, a third reversing mechanism, a third laminating mechanism, a fourth reversing mechanism, an exhaust mechanism and a second reversing rotary shaft are sequentially arranged on the base; an external protection layer sheet to be laminated is sequentially reversed, laminated and exhausted through the first reversing rotary shaft, the first reversing mechanism, the first laminating mechanism, the second reversing mechanism, the second laminating mechanism, the third reversing mechanism, the third laminating mechanism, the fourth reversing mechanism, the exhaust mechanism and the second reversing rotary shaft, and is then collected and coiled through a coiling mechanism. The roller press mechanism is used for laminating and forming the external protection layer sheet, and is operated automatically, so that the work efficiency and the product quality are improved, and the smoothness of a product is improved.

Description

technical field [0001] The invention relates to a rolling mechanism, in particular to a rolling mechanism used for the production of outer protective layer sheets. Background technique [0002] Pipeline crossing project is a pipeline project in which transportation pipelines are laid underwater or underground through rivers, lakes, railways, highways and other areas. [0003] Pipelines are easily corroded in underwater or underground environments, and are generally protected by coating anti-corrosion coatings. However, this method has a short protection period and still poses safety hazards when used for a long time. [0004] The applicant has developed a six-layer structure of the outer protective layer sheet, the sheet from bottom to top is "upper bearing film, outer epoxy vinyl ester base layer, glass fiber reinforced layer, glass fiber stitched mat , Inner epoxy vinyl ester base layer and lower bearing film", this kind of sheet has light weight, high tensile strength an...
