Abstract
The invention provides a packaging film pulling method. According to the method, a first clamping mechanism and a second clamping mechanism are sequentially arranged in the conveying direction of a packaging film so that the packaging film can be alternately clamped, sealed and pulled at the same time, when the first clamping mechanism moves by half of the length of a packaging bag, the packaging film is clamped by the second clamping mechanism, the second clamping mechanism and the first clamping mechanism move at the same speed in the same direction, and the position where the packaging film is clamped by the second clamping mechanism overlaps with the position where the packaging film is clamped by the first clamping mechanism all the time; when the first clamping mechanism and the second clamping mechanism move by one fourth of the length of the packaging bag at the same speed in the same direction, the first clamping mechanism lets the packaging film go and quickly returns to the initial position of the first clamping mechanism, and the second clamping mechanism lets the packaging film go and returns to the initial position of the second clamping mechanism after performing continuous uniform motion by one fourth of the length of the packaging bag. The method has the advantages that the packaging speed is greatly increased while the sealing effect of the packaging bag is enhanced, loss of a user caused when the packaging bag is not sealed tightly is reduced, and meanwhile the production speed is increased.

When clamping mechanism one moves to the stroke of 0.5 package length, clamping mechanism two steps up packaging film, and motion synchronized in the same way with clamping mechanism one, now clamping mechanism two and clamping mechanism one are at a distance of the length of 1 packaging bag, and the position that clamping mechanism two clamps packaging film is be clamped in the position that tight mechanism one clamped overlappingly all the time;
When the stroke of clamping mechanism one and the synchronized in the same way motion of clamping mechanism two 0.25 package length, clamping mechanism one unclamps packaging film and returns rapidly its initial position; Now clamping mechanism two continues after the stroke of uniform movement 0.25 package length on packaging film throughput direction, and clamping mechanism two unclamps packaging film and returns its initial position, and clamping mechanism one is at the tight packaging film of its initial position closed clamp;
Afterwards, repeat the action of above-mentioned steps successively always, realize traction and the secondary involution of packaging facial mask; Wherein
Conveying mechanism one and conveying mechanism two drive clamping mechanism one and clamping mechanism two to do back and forth movement, two clamping mechanisms respectively, are respectively clamping mechanism one and clamping mechanism two, are successively set on the throughput direction of packaging film.
Further, described clamping mechanism one and clamping mechanism two are all be arranged on by two the cylinder that a connecting panel is also arranged in opposite directions carry out the clamping of packaging film or loosen.
Further, described conveying mechanism one and conveying mechanism two are belt transmission mechanism, and driven by motor belt transmission mechanism works.
The beneficial effect of packaging film draw gear of the present invention and method is:
Add an involution to packaging bag enclosing, while strengthening the involution effect of packaging film, package speed promotes greatly, can reach about 100 bags/point; Reduce the loss that user does not sternly cause due to involution, improve speed of production simultaneously, reduce labor intensity;
And apparatus structure is simple, it is convenient to realize, and tooling cost is low, improves the effect of manufacturing line.
