Problems solved by technology

The main problems are: low production capacity, more labor, high labor intensity, low degree of automation, difficult quality control, which is not conducive to large-scale production, and the performance of foam is far inferior to that of continuous foaming block foam
In addition, with the application of foam in many fields, the size requirements of the produced foam are also different, and the use of fixed-width production lines is likely to cause waste or fail to meet the requirements

Embodiment Construction

[0023] A continuous foaming production line of polyurethane hard foam with adjustable width, such as figure 2 and image 3 As shown, at least one of the crawler belts 16 and 18 on both sides of the crawler production line used in the polyurethane rigid slab foam foaming and curing molding part can move left and right, so that the width of the produced foam can be adjusted.

[0024] The width-adjustable continuous foaming line includes a production line frame 7, a crawler conveyor belt 10 at the bottom, crawler conveyor side plates 16, 18 on the left and right sides, and an electric width adjustment device. Foaming production line is fixed by framework 7 conveying crawler belt 16,18 and lower conveying crawler belt 10 below. When foaming is produced, the foam is foamed and solidified on the synchronous three-sided conveyor belt, and then sent to the cutting section.

[0025] Wherein, the electric width adjustment device part is composed of multiple groups of worm gear screw ...

Abstract

The invention discloses a width-adjustable continuous foaming production line of rigid polyurethane foam. The width-adjustable continuous foaming production line comprises a bottom crawler-type transmitting belt, a left crawler-type transmitting side plate and a right crawler-type transmitting side plate. The bottom crawler-type transmitting belt, the left crawler-type transmitting side plate and the right crawler-type transmitting side plate are fixedly connected with a production line frame; and an electric width adjusting device is connected with the left crawler-type transmitting side plate and the right crawler-type transmitting side plate and adjusts movement of at least one of the left crawler-type transmitting side plate and the right crawler-type transmitting side plate. By means of the width-adjustable continuous foaming production line, continuous production of a factory is achieved, quality is stable, cost is low, the production efficiency is high, and mass production can be achieved; and in addition, the width of the production line can be adjusted, the material cutting rate of a product is increased, the product cost is reduced, and the foam has a wider application range accordingly.

Description

technical field [0001] The invention relates to a polyurethane hard foam continuous foaming production line with adjustable width. Background technique [0002] Due to its excellent physical properties and special processing and application characteristics, polyurethane rigid foam has continuously increased its application share in the building energy-saving market. As the most excellent thermal insulation building material, polyurethane rigid insulation board is easy to install, and can avoid or reduce maintenance costs during use. It is widely used in building enclosure insulation. The national plan is to complete the energy-saving transformation of all buildings in the country by 2020. It is predicted that 150 million m 2 The above polyurethane energy-saving insulation board has a very huge market. [0003] At present, domestically produced polyurethane insulation boards are cut from rigid polyurethane block foam produced in batches. This method has a small production v...
