        I. Summary of technical implementation steps

       The present technology relates to the field of vacuum forming machines, and in particular to an EPS molding machine central vacuum system and an EPS forming system.

       ⅰ.Technology Introduction

        In the process of EPS sheet production using an EPS molding machine, the formed foam is generally cooled by vacuum cooling. Since the EPS molding machine itself does not have a vacuum pump, the vacuum required in the working process needs to be provided by a special vacuum system. In the existing EPS molding machine production line, at least one vacuum pump of 7.5kw is required for the vacuum system of each EPS forming machine. And a 1.5kw pumping machine. Taking a production line with 10 EPS forming machines as an example, a 90kw motor in the vacuum system of the entire production line operates uninterruptedly, consumes a large amount of electricity, has a large noise, and has many motor failures. At the same time, the existing EPS molding machine needs to start a vacuum system every time a EPS sheet is produced. During the continuous production process, the vacuum system motor will continuously start/stop the cycle, which is often accompanied by the start of the high-power motor. Strong instantaneous current, instantaneous current under long-term operation not only has a great impact on transformer safety, but also accumulates huge power waste.

       ⅱ.Technical realization ideas

        In view of the defects existing in the prior art, the purpose of the present technology is to provide a central vacuum system and an EPS forming system for an EPS molding machine, which can reduce the power consumption of the vacuum system and save the production cost without changing the structure of the existing device. The role.
