Positive/negative pressure vacuum film covering machine

Abstract

The invention discloses a positive / negative pressure vacuum film covering machine, and belongs to the technical field of mechanical devices. The positive / negative pressure vacuum film covering machine is composed of a main machine, a hydraulic system, a heating system, an electric system and a positive and negative system. The main machine comprises an upper cylinder, an upper beam, an upper vacuum chamber, a film pressing plate, a lower vacuum chamber, a lower beam, stand columns, a film pressing cylinder and a lower cylinder. The hydraulic system is located on the rear side of the main machine. The heating system is arranged at the top end in the upper vacuum chamber. The electric system is located on the right side of the main machine. The positive / negative pressure system is located on the left side of a machine body. A main body is a closed cavity, the closed cavity is partitioned into two independent air chambers through a decorative film, the forming process is conducted in the same closed space and not likely to be affected by the external environment, and the stability of processing can be improved so as to achieve the purpose of improving positioning accuracy; the elongation of the film can be improved by the adoption of prestretching, the interior of a plastic part can be wrapped by the film smoothly, and the high-quality film-decorative plastic part is obtained.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and relates to a laminating machine, in particular to a positive and negative pressure vacuum laminating machine (TOM). Background technique [0002] Laminating machines are widely used in home appliance appearance decoration, food packaging, architectural decoration, furniture production and other industries. With the improvement of people's life quality, consumers in the above industries are no longer satisfied with the requirements for green and environmental protection products. The exterior decoration requirements are constantly improving. Diversified product market demand poses new challenges to the traditional lamination process. The traditional vacuum lamination technology adopts the principle of blistering. When it is used for product surface lamination, air bubbles will be generated due to poor exhaust, and the working hours are long. Safety performance Low, low efficiency...
