Abstract

The invention discloses an efficient feeding and stretching packaging machine based on thermal forming packaging. The efficient feeding and stretching packaging machine comprises a machine base, wherein a machine frame is vertically arranged at one side of the top of the machine base, a channel is formed in the other side of the top of the machine base, a lower film roller frame is arranged at one end of the channel, and a lower film roller is movably connected to the inner wall of the lower film roller frame; and a discharging hopper frame is arranged at the other end of the channel, a discharging hopper is rotationally connected to the inner wall of the discharging hopper frame, a cutting part is fixedly connected to the outer wall of the top of the discharging hopper frame, and a conveying belt support is arranged at the side, close to the channel, of the machine base. According to the efficient feeding and stretching packaging machine, two side films are vertically input and pressed at the two sides of a product, heat sealing and hot pressing are synchronously carried out, vacuumizing is carried out, the pressure difference is generated in a heat sealing cavity, gas in a heat sealing area is exhausted during heat sealing, gas exhausting, synchronous heat sealing and vacuumizing operation in a package are achieved while the product heat sealing is achieved, and various problems caused by heat sealing after the product is vacuumized can be solved.

Description

technical field [0001] The invention relates to the technical field of packaging machines, in particular to a high-efficiency feeding stretch packaging machine based on thermoforming packaging. Background technique [0002] Stretch packaging machine, also known as wrapping machine, or stretch film wrapping machine, is a packaging machine that realizes mechanized wrapping instead of manual wrapping. A machine that wraps products under tension using stretch film. It is often used to wrap products that have accumulated on a tray or platter together with the tray or platter. [0003] In the existing stretch packaging machine, the material is fed directly on the bottom film through one end, and there will be a pollution source on the side where the packaging film is attached to the product. Simultaneously, the stability of the heat seal will decrease after vacuuming, which will affect the packaging of the product. Contents of the invention [0004] Based on the technical prob...
