Description

Air-cushion film machine automatic cutting means

Technical field

The utility model relates to a kind of air-cushion film machine, and what be specifically related to is a kind of air-cushion film machine automatic cutting means.

Background technology

The air-cushion film machine is the production facilities of air-cushion film (claiming bubble chamber film again) goods; this equipment is raw material with low density polyethylene (LDPE) (LDPE); make the air-cushion film packing articles; have the packaging protecting effect of protection against the tide, dustproof, antidetonation, electrostatic prevention, it is widely used in the packing of electronic product, ceramic, glass ware, hardware, furniture and exquisite workmanship or the like.The present air-cushion film machine that uses, air-cushion film all is to adopt manually air-cushion film is cut after being wound into tube on the collecting shaft basically, its shortcoming is: speed of cut is slow, otch is irregular, has increased working strength of workers.

Summary of the invention

In view of the problem that present known technology exists, the technical problems to be solved in the utility model be to provide a kind of improve speed of cut, otch neat, save artificial air-cushion film machine automatic cutting means.

For solving the problems of the technologies described above, the utility model takes following technical scheme to finish: air-cushion film machine automatic cutting means, be located at the rewinding reel next door of air-cushion film machine, it is characterized in that: described air-cushion film machine automatic cutting means comprises swing arm and is located at cutting knife, film idler roller and Rodless cylinder in the swing arm, cutting knife is fixed on the slide block of Rodless cylinder, the cylinder body of Rodless cylinder is captiveed joint with swing arm, the film idler roller is located at the dual-side of cutting knife, swing arm is rotatable to be located on the frame, and swing arm is connected with drive element.

The utility model has increased the air-cushion film automatic cutting means on the basis of existing air-cushion film machine, consequently air-cushion film is wound into the tube back and just can carries out fly cutter automatically and cut, and has saved manually, improved speed of cut, and otch is very neat.

Description of drawings

Fig. 1 is a structural representation of the present utility model; Fig. 2 is the lateral plan of Fig. 1.

The specific embodiment

With reference to accompanying drawing 1,2, this kind air-cushion film machine automatic cutting means, be located at the rewinding reel next door of air-cushion film machine, comprise swing arm 5 and the cutting knife of being located in the swing arm 52, article two, film idler roller 1,4 and Rodless cylinder 3, cutting knife 2 is fixed on the slide block of Rodless cylinder 3, the cylinder body of Rodless cylinder 3 is captiveed joint with swing arm 5, article two, film idler roller 1,4 are divided into the dual-side of cutting knife 2, the effect of film idler roller is when cutting knife cuts air-cushion film, together air-cushion film is strained with another idler roller (not drawing among the figure) on the rewinding support, be convenient to cutting knife air-cushion film is cut, described swing arm 5 rotatable being located on the frame 6, swing arm 5 is connected with cylinder 7.

The utility model is like this work: when the rewinding reel is finished rolling and need be cut air-cushion film, cylinder action lifting swing arm, two idler rollers in the swing arm and and the rewinding support on another idler roller will wait that together the air-cushion film at the place of cutting strains, Rodless cylinder action subsequently, the slide block of Rodless cylinder drives cutting knife and moves rapidly, and air-cushion film is cut, and then slide block drives the cutting knife return, cylinder drives the swing arm return simultaneously, waits for the work that cuts next time.
