Description

Feeding mechanism of plasticizing machine

Technical Field

The utility model belongs to the technical field of sheet production, and particularly relates to a feeding mechanism of a plasticizing machine.

Background

The composite waterproof roll is one kind of waterproof roll compounded with high strength polypropylene fiber filament nonwoven fabric, and through one-step compounding in an automatic production line. The product is developed according to the new requirements of modern waterproof engineering and waterproof and impermeable materials on the basis of fully researching the existing waterproof and impermeable products.

The existing polyethylene polypropylene composite waterproof coiled material is characterized in that polyethylene particles and additives are mixed in the production process, then the polyethylene particles and the additives are integrally put into plasticizing equipment for heating and stirring, so that the polyethylene particles reach a flowing state and have certain plasticity, but in the feeding process of a plasticizing machine, as the polyethylene particles are generally cooled through a cooling water tank in the production cooling process, a large amount of water is adhered to the surfaces of the polyethylene particles, and in the high-temperature plasticizing stage, water vapor is required to be discharged after the water is evaporated at a high temperature, otherwise the pressure in the plasticizing machine is increased, and toxic gases released during heating of the polyethylene are discharged together due to the fact that the water vapor is discharged at the moment, so that cancerogenic risks are caused.

For the problems in the related art, no effective solution has been proposed at present.
