Through a cylinder control iron rod slide up and down, convenient feeding. Roll with screw QQ dead. After feeding, bundle the film with a low pressure wide bag. The reel is turned counterclockwise.

(2) tail frame rubber roller

The two rubber rollers are pressed and driven by a small motor to rotate and pull the film.

(3) Rolling curtain

The rolling curtain is generally made of mat or plastic, which mainly plays the role of press material and tension control. An inductor behind the cursor detects whether there is a film in front of it to control the running and stopping of the tail frame cots motor. If there is, stop; if there is nothing, move.

(4) suspension plate

Made of stainless steel, play a flat film, prevent the bag wrinkles, ensure the size of the bag function. So the pause board should be flat. Light weight items can be placed above the film to flatten the film.

(5) Light eyes

Control bag length, cut position, and color label length by tracking changes in the level of the printed color on the bag. The optical eye can be moved forward and backward by adjusting the screws at both ends, and the optical eye stop position can be corrected (2-3mm). A piece of white paper can be placed under the film that the light eye is facing to increase its sensitivity. If the pattern is complex, you can also pad white paper on the pattern to ensure that the square pattern under the light is straight, without other colors before and after, and pattern interference.

Light eye location: ① flat straight line. (2) There is no other pattern interference before the pattern, otherwise it will affect the optical eye stop.

(6) Seal

The sealing knife is triangular, and there are a group of rollers at each end to ensure that the film runs smoothly at the sealing knife. Knife roller is generally heat-resistant silicone roller. There is a heat-resistant tape on the knife and on the silicone roller. There are two copper tiles at both ends of the sealing knife to control the sealing knife up and down, so the lubricating oil should be often added here.

Change the knife cloth: ① First use sandpaper to polish the sealing knife.

(2) Stick the knife cloth in the middle of the knife, toward both sides to avoid bubbles and folds in the middle of the knife cloth, otherwise it will lead to virtual seal.

(7) alignment bar

By adjusting the screw to control the height of the iron bar, and then adjust the film cutting position.

(8) corrugated rubber roller

There is a spring on the roller to avoid electrostatic membrane entanglement, there is a special motor to control its operation. There are special electrostatic removal devices before sealing and after cutting the knife (a iron bar with a row of iron needles).

(9) Cutting knife

There are two upper and lower cutting knives, the lower cutting knife is fixed, the blade incline upward about 5° Angle, and the film is cut by the upper cutting knife. The cutting knife is mostly cast iron, with lubricating oil at both ends. The setting screw of the upper cutter can be adjusted to control the distance between the upper cutter and the lower cutter.

(10) Fold

Folding is divided into three steps, bag making machine folding automatically. If the customer requires the word to face out when packing, the roll is rotated clockwise when winding. If the words are facing inward, the roll rotates counterclockwise when winding up.
