关键词:真空包装四连杆机构热合器
ABSTRACT
Vacuum pack machine is one of the pack mechanisms being widely technology have the many important funtions as antisepsis, protection against the damp, protection against the rust, and advance the products performance,reduce the wastage, conomize the fare of storage and transportation, and have some contributions to people's health. Vacuumized technology has been used in the industry of foodstuff, phsic,electron instrument, precision meter, chemical industry manufacture the development Vacuum pack techniques,the pack mechanisms are improving andperfecting gradually. The development directions vacuum pack mechanism are Low cost,intelligentizing and high quality.
This thesis analysed the deficiency of current pack equipments, consulted relatedmaterials, improved design of the existing vacuum pack machine which is single cover board and double position. The mostly improvements can be list as follows: rechoose the heat transformer and advance the quality of the seal; redesign the atertight groove andbar and melioration the seal character of the um room; redesign the four link mechanism and perfect the stability and flexibility of the um room movement.
Key words: vacuumize four link mechanism fusion implement
