Full-automatic film seal-cutting packaging machine

Abstract

The invention discloses a full-automatic film seal-cutting packaging machine. The full-automatic film seal-cutting packaging machine is characterized by comprising a machine frame, a film conveying and sleeving device, a seal-cutting device and a conveying device; the conveying device comprises a first conveying mechanism, a second conveying mechanism and a third conveying mechanism; the seal-cutting device comprises an upper seal-cutting piece, a lower seal-cutting piece, a vertical rod and a swing piece; when the swing piece is driven to rotate in the forward direction or in the backward direction, the upper seal-cutting piece and the lower seal-cutting piece are driven to get close to or get away from each other; the swing piece is arranged movably in the vertical direction, so that the seal-cutting position when the upper seal-cutting piece and the lower seal-cutting piece are folded and the relative height of the working plane of the conveying device are adjusted; the machine frame is provided with an encoder and a programmable controller; the encoder is used for monitoring the stir quantity in real time and feeding the stir quantity back to the programmable controller; and the driving distance of a second motor is the new film packaging length of a packaged product. By the adoption of the full-automatic film seal-cutting packaging machine, the front film allowance length and the rear film allowance length of the product can be kept consistent, the height of a longitudinal seal-cutting mechanism can be easily adjusted according to to-be-packaged objects of different specifications, and the packaging quality is improved.

Description

technical field

[0001] The invention relates to the field of packaging machines, more specifically, it relates to an automatic film sealing and cutting packaging machine. Background technique

[0002] With the continuous improvement of people's living standards, the rapid development of my country's packaging industry has been stimulated. Packaging machine is one of the fastest-growing packaging machinery and has broad development prospects, especially shrink packaging machines. The shrink packaging machine is a machine that wraps the product with a heat-shrinkable film and then heats it so that the film shrinks and wraps the product.

[0003] In the prior art, before the shrink wrapping machine heats the film, it is necessary to rely on the film sealing and cutting packaging machine to wrap the film on the product, but the film sealing and cutting packaging machine needs to leave a certain amount of film residue on the front and rear of the product The amount is for the s...
