Automatic fitting vacuum packaging machine

Abstract

The invention belongs to the technical field of packaging equipment, and particularly relates to an automatic fitting vacuum packaging machine. The machine comprises a rack, an upper vacuum heating assembly, a lower vacuum chamber assembly, a vacuum embedding cavity, a film rolling roller and a film clamping and conveying device, wherein a dumping device is fixed in the lower vacuum chamber assembly; a lower heating polar plate is fixed at the top end of the dumping device; the film clamping and conveying device comprises a gear sliding rod, a guide rail, a conveying motor, a conveying block, a lower clamping plate, an upper clamping plate, a servo motor, a hydraulic cylinder, a sliding block and a sliding rail. The upper clamping plate is controlled to rotate through the film clamping and conveying device, so that the upper clamping plate and the lower clamping plate clamp a packaging film, the conveying motor works, the packaging film is conveyed from one end of the rack to the other end of the rack, a supporting basket is covered with the packaging film, therefore, the film laying work can be automatically completed, and the working efficiency can be effectively improved; and by arranging the dumping device, products can be directly dumped and taken out after being packaged, and compared with the mode of taking out manually or via a mechanical arm, the dumping device is safer and more reliable.

Description

technical field [0001] The invention belongs to the technical field of packaging equipment, and in particular relates to an automatic vacuum skin packaging machine. Background technique [0002] Vacuum skin packaging technology is a form of vacuum packaging. When packaging cold and fresh food, a negative pressure is formed on the top of the film by vacuuming, so that the packaging film is close to the food. After heating, the transparent packaging film is vacuum formed according to the shape of the food. , close to the food, can effectively maintain the color, juice, fragrance and freshness of the food, has the double effect of sculpture-like stereoscopic visual display and vacuum preservation, and the pre-heating packaging film is not easy to produce wrinkles, compared with the traditional Packaging technology, vacuum body-fitting technology can not only isolate food from the outside world, because the gravitational force is evenly displayed on the packaging box, it can eff...
