Plastic wrap packaging machine

Abstract

The invention discloses a preservative film packaging machine. An existing semi-automatic preservative film packaging machine easily infects bacteria during packaging, and a fully-automatic preservative film packaging machine is not suitable for being used in a supermarket or by individual household. A controller of the preservative film packaging machine controls a preservative film circulating pulling device, a preservative film cut-off device, a preservative film clamping device and a tray lifting device to act; a preservative film is arranged on a preservative film optical axis in a sleeving mode, and one end of the preservative film is continuously pulled out by the preservative film circulating pulling device; the pulled-out preservative film is cut off by the preservative film cut-off device after being clamped by the preservative film clamping device; when a tray conveyed by the tray lifting device lifts, the preservative film clamping device enables two sides of the cut-off preservative film to package the tray; and when the tray is manually taken out, the other two sides of the preservative film package the tray. According the preservative film packaging machine disclosed by the invention, sanitation hidden danger is solved, a preservative film utilization rate is increased, and production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of food packaging and sealing, and in particular relates to a fresh-keeping film packaging machine capable of automatically sealing and packaging food. Background technique [0002] Most of the existing plastic wrap packaging machines are semi-automatic, with a single function, and can only complete cutting. The manual packaging is mainly used. Using a hot knife to cut consumes a lot of energy, and the cutting is not smooth. It often needs to be broken manually. The utilization rate is very low, and multi-layer packaging is required to completely seal. After the packaging is completed, the plastic wrap is partially exposed, and the plastic wrap needs to be pulled manually every time it is packaged. The fully automatic machinery on the market has high cost, complex structure, large floor space, complex replacement of plastic wrap, high power consumption of the equipment, the use of a fully enclosed structure ...

Problems solved by technology

[0002] Most of the existing plastic wrap packaging machines are semi-automatic, with a single function, and can only complete cutting. The manual packaging is mainly used. Using a hot knife to cut consumes a lot of energy, and the cutting is not smooth. It often needs to be broken manually. The utilization rate is very low, and multi-layer packaging is required to completely seal. After the packaging is completed, the plastic wrap is partially exposed, and the plastic wrap needs to be pulled manually every time it is packaged.

The fully automatic machinery on the market has high cost, complex structure, large floor space, complex replacement of plastic wrap, high power consumption of the equipment, the use of a fully enclosed structure is easy to cause sanitary dead ends, and the maintenance cost of the equipment is high, and the market application area is narrow , not suitable for supermarkets or self-employed
