Description

Demolding production line for perlite insulation board

Technical Field

The utility model relates to an heated board processing technology field, concretely relates to perlite heated board's demolding production line.

Background

The heat insulation board is a building material advocated by modern energy-saving buildings. The heat-insulating board has various functions of water resistance, fire resistance, moisture resistance and the like besides heat insulation according to different requirements, and has different functions and different formulas. However, most of the heat insulation materials contain cement, and the strength of the heat insulation plate is improved through the cement.

The existing insulation board is mostly extruded and formed through a hydraulic press, the insulation board prepared by the method is required to be not too thick, if the insulation board is too thick, uneven stress can exist during hydraulic pressure, uneven compactness of the insulation board can be caused, the strength is reduced, and therefore the overall use performance of the insulation board is affected. For the reasons, the insulation boards formed by hydraulic forming are all thin, and the thickness of the insulation boards in the final use state is generally 3-6 cm; but the heated board is too thin, and in the maintenance process after the hydraulic forming, cement hydration water therein runs off very easily, causes heated board intensity to descend, and the period needs often moisturizing, leads to the maintenance time longer, generally needs about 3 days.

In addition, adopt the mode of hydraulic pressure extrusion molding, crush the perlite granule easily, lead to the clearance between the granule to diminish, although increased the intensity of heated board to a certain extent, nevertheless because the clearance between the granule diminishes for the air between the granule reduces, thereby causes the heat preservation effect reduction of heated board.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a demolding production line of pearlite heated board to the heated board causes the problem that heated board heat preservation effect reduces through extrusion in solving prior art.

In order to achieve the above object, the utility model adopts the following technical scheme:

a demolding production line of a perlite insulation board comprises a feeding unit, a mixing unit, a material conveying unit and a demolding unit, wherein the demolding unit comprises a material storage hopper, a material pushing trolley is connected below the material storage hopper in a sliding mode, a cavity used for being in butt joint with a discharge hole of the material storage hopper is formed in the material pushing trolley, and the cavity is formed by enclosing the side wall of the material pushing trolley; one side of the storage hopper is connected with a die for demolding and forming the heat-insulation plate, and a vibration mechanism for vibrating materials in the die and a driving mechanism for driving the vibration mechanism to move are arranged above the die.

Compared with the prior art, the utility model discloses a principle and beneficial effect: various raw materials are added into the mixing unit in batches through the feeding unit, and then the raw materials are uniformly mixed through the mixing unit, so that the prepared heat-insulating plate can be uniform, and the effect of effectively preserving heat is achieved. The uniformly mixed materials are conveyed to the demolding unit through the conveying unit, the materials firstly enter the material storage hopper to be stored, and the cavity of the material pushing trolley is in butt joint with the material storage hopper, so that the materials entering the material storage hopper are preferentially filled into the cavity; after the materials enter the cavity, the materials slide towards the direction of the die through the pushing trolley, and the cavity is formed by enclosing the side wall of the pushing trolley, namely an upper opening and a lower opening of the cavity, the materials in the cavity fall into the die, and the non-cavity part of the pushing trolley gradually blocks the discharge hole of the material storage hopper to stop feeding the materials into the cavity, so that intermittent feeding into the die can be realized; simultaneously can be through changing reinforced number of times and reinforced every time how much, fill into the material of different volume in the mould promptly, reach the effect that production has different thickness heated board.

After the material enters the die, the vibration mechanism is driven by the driving mechanism to move towards the die, and the vibration mechanism extends into the die to be in contact with the material, so that the material in the die is vibrated and tamped by the vibration of the vibration mechanism.
