Problems solved by technology

[0002] In the production process of the insulation board, the foam particles are pre-foamed and then transferred to the curing bin for curing. After the curing is completed, they are transferred to the pre-storage hopper on the top of the board forming machine for pre-storage, and then added to the board forming machine for molding. On the conventional pre-storage hopper The feeding method directly introduces the matured particles in the curing chamber through the fan. In this way, the fan blades will directly contact the foam particles, and the fan blades are in a fast rotating state, and the fast rotating blades will hit the foam particles. , thereby destroying the external shape of the foam particles, so that the foam particles cannot guarantee a regular near-circular shape, resulting in the destruction of the regular gaps between the foam after the foam is set, affecting the normal thermal insulation performance of the insulation board

Abstract

The invention relates to the field of production of thermal insulation sheets, and in particular, relates to a foam sheet machine pre-storage material device capable of effectively preventing particledamage, wherein the device includes a feeding pipe, a pre-storage hopper having the top communicating with the feeding pipe, and a fan feeding mechanism. According to the device, a material is suckedby negative pressure, so a fan does not directly make contact with particles, the shape of the particles is prevented from being damaged, the regular shape of the particles after foaming molding is ensured, and the performance of thermal insulation sheets is ensured.
