Pressure-regulating vacuum round and square dual-purpose three-dimensional continuous foaming machine

Abstract

The invention discloses a pressure-regulating vacuum round and square dual-purpose three-dimensional continuous foaming machine, which comprises a vertical vacuum foaming cabin, a pressure-regulating conveying cabin, a pressure-regulating storage cabin and a vacuumizing air distribution system, wherein the vertical vacuum foaming cabin is communicated with the pressure-regulating conveying cabin; the pressure-regulating conveying cabin is communicated with the pressure-regulating storage cabin; the pressure-regulating storage cabin and the pressure-regulating conveying cabin are provided with air distribution cabins; the air distribution cabins are communicated with the pressure-regulating conveying cabin by air pressure balancing conversion control valves; the air distribution cabins are communicated with the pressure-regulating storage cabin by air distribution valves; the vacuumizing air distribution system is communicated with the air distribution cabins; and straight-inserting adjustable lifting chain plates are arranged in the vertical vacuum foaming cabin, and can be two semi-barrel lifting chain plates or can be two long-plate lifting chain plates. The pressure-regulating vacuum round and square dual-purpose three-dimensional continuous foaming machine not only can generate round foam but also can generate square foam so as to satisfy the market requirement to the greatest extent, is safe and environmentally friendly, is free from pollution and has the advantages that land occupation is small, one machine has two purposes, the product quality is high, and cost can be lowered by 20-30%.

Description

technical field [0001] The invention relates to the technical field of polyurethane soft foam foaming equipment, and is a three-dimensional continuous foaming machine of a pressure-regulating type, vacuum, radius, and dual-purpose. Background technique [0002] At present, the existing domestic foaming technology mostly adopts the traditional method to carry out the foaming operation in the normal pressure process, and uses freon and methylene chloride, which are harmful to the human body, as foaming aids, which have a large degree of pollution to the environment, High consumption of raw materials, uneven pores of finished products and other disadvantages; and the equipment installation occupies a large area, cannot be used for multiple purposes, and the production cost is high. Contents of the invention [0003] The object of the present invention is to provide a pressure-regulating type vacuum, square and radius dual-purpose three-dimensional continuous foaming machine; ...
