A multi-layer composite board processing device

Abstract

The invention discloses a processing device for a multi-layer composite panel, belonging to the fields of drying and curing machines of panels. The processing device comprises a placement frame, a support frame and a furnace body, wherein the support frame is placed between the placement frame and the furnace body; upper and lower extrusion wheels are arranged on the placement frame, the upper extrusion wheel can move up and down, and travel switches are respectively arranged on two sides and end parts of contact sites of the upper and lower extrusion wheels; a vacuum bag is arranged on the support frame, and a pressure sensor is arranged on the vacuum bag and is connected with a vacuum pump; a relay, a movable furnace cover heating device and an air flue are arranged in the furnace body, a plurality of air outlets are formed in the air flue, a draught fan is arranged at an inlet of the air flue, and the travel switches, the vacuum pump, the pressure sensor, the draught fan and the heating device are respectively connected with the relay; and conveying devices are respectively arranged on the surfaces of the placement frame and the support frame and in the furnace body. The processing device is simple in structure, reasonable in design, low in cost, high in rate of finished products and high in production efficiency and can be automatically controlled, and the dry curing time of a joint panel is short.

Description

technical field [0001] The invention relates to the field of plate drying and curing equipment, in particular to a multilayer composite plate processing device. Background technique [0002] Along with the continuous improvement of living standards, people often will bond various patterns on the surfaces of plates such as glass and planks to increase the appearance. At present, the commonly used equipment is only the extrusion device and the drying device, and there is no vacuum device, so that after extrusion, there may be tiny air bubbles between the plates, which will affect the drying effect; the extrusion equipment is generally simple mechanized operation, It is not intelligent enough and wastes energy. The drying and curing equipment is generally hot air drying and curing or resistance wire heating and drying and curing. The disadvantage of hot air drying and curing is that coal needs to be burned, which increases environmental pollution, and smoke exhaust pipes and a...

Problems solved by technology

At present, the commonly used equipment is only the extrusion device and the drying device, and there is no vacuum device, so that after extrusion, there may be tiny air bubbles between the plates, which will affect the drying effect; the extrusion equipment is generally simple mechanized operation, Not intelligent enough, waste of energy, drying and curing equipment is generally hot air drying and curing and resistance wire heating and drying and curing

The disadvantage of hot air drying and curing is that coal needs to be burned, which increases environmental pollution. In addition, smoke exhaust pipes and ash outlets must be installed. The structure of the ventilation pipeline is complicated and the manufacturing cost is high.

The resistance wire is heated, dried and cured. The disadvantage is that the resistance wire cannot directly heat the plate. It is necessary to add a layer of heat-resistant bricks outside and rely on heat radiation for heating, which increases the weight of the equipment, and the heating temperature of the resistance wire is difficult to control. It often deforms and cracks the plate, making it difficult to guarantee the pass rate
