Abstract

The invention discloses a central vacuum system of a foam-plastic forming machine. The central vacuum system is characterized in that a rack is provided with three condensing barrels (3), a water discharging box (6) and a plurality of vacuum pumps (4); a gas inlet pipeline (1) is communicated with the condensing barrels (3); the upper parts of the condensing barrels (3) are communicated with a distribution pipeline (2) by upper valves; the lower parts of the condensing barrels (3) are communicated with the water discharging box (6) by lower valves; the middle parts of the condensing barrels (3) are communicated with auxiliary vacuum pipelines (5) by auxiliary vacuum valves; the vacuum pumps (4) are communicated with a distribution pipeline (2) and the water discharging box (6); the condensing barrels (3) are provided with a plurality of sprayers (7); and all the parts form the central vacuum system. The central vacuum system disclosed by the invention has the advantages that the relatively independent condensing barrels are adopted, independent pre-vacuumizing can be adopted for vacuumizing, and no pressure drop of the whole pipeline can be maintained in working, so that the qualification rate of a product is guaranteed.

Description

technical field [0001] The invention relates to the field of machinery, in particular to the central vacuum system of a foam molding machine. Background technique [0002] At present, when the central vacuum system of the foam molding machine on the market is working, there will be a certain pressure drop when the drainage is switched, which will affect the quality of the produced products. Contents of the invention [0003] The purpose of the present invention is to provide a central vacuum system of a foam molding machine, which ensures the pressure in the pipeline and solves the problem of pressure drop in the central vacuum system. [0004] The technical solution adopted by the present invention to solve the technical problem is: the central vacuum system includes an air intake pipeline 1, a distribution pipeline 2, a condensation bucket 3, a vacuum pump 4, an auxiliary vacuum pipeline 5, a drainage tank 6 and a shower 7, and Three condensing barrels 3, a drainage box...
