Description

Technical Field

[0001] The invention relates to a conveying and loading and unloading mechanism for a wide asbestos substrate plate. Background Art

[0002] Asbestos substrate board is made of asbestos, glass fiber, clay and other materials according to scientific formula. It has strong resistance to tension and pressure. Asbestos substrate board is mainly used for insulation, heat preservation and sound insulation, boilers, steel mills, chemical plants, aluminum foundries and other occasions, and is also suitable for insulation of general electrical appliances. As a sealing element, asbestos substrate board ensures the complete transmission of substances and is an important industrial product in my country's modernization construction. The vulcanization treatment of asbestos substrate board is to enhance its physical properties, improve heat resistance and chemical corrosion resistance, and improve processing performance. During the processing, the asbestos substrate board before vulcanization needs to be transported to the vulcanization box one by one. In view of the soft physical properties and large specifications of single asbestos substrate board, the electrostatic adsorption of stacked substrate boards is not easy to separate, resulting in low production efficiency in the manual operation process. A wide-width asbestos substrate board conveying and loading and unloading mechanism is needed to adapt to the vulcanization treatment and conveying of asbestos substrate boards under different needs, reduce the labor intensity of workers, and improve the production efficiency of enterprises.
