The cutter part is faulty. 

(1) The film cannot be cut: 

Reason 1: The gap between the moving knife and the fixed knife is not adjusted properly. Adjustment method: There are two short tightening screws on the outside of the fixed knife, and two long pressing screws on the outside of the fixed knife. When the blade of the movable knife is close to the fixed knife, the film is cut by the grinding of the two knives. The gap between the blades of the two pillow-type packaging machines is preferably 1/100mm. At the same time, the film is clamped and cut by hand while adjusting, and the cutter clutch should be disengaged when adjusting. 

Reason2: The cutting blade is damaged and small with a whetstone grinding, and the large damage is repaired with a grinder. 

Reason 3: Poor installation of the cutter, poor clutch clutch of the cutter, and disengagement of the positioning key. Solution: Carefully check all parts and re-tighten them.

 3. Failure of horizontal sealing heat roller: poor sealing.

 Cause: Poor thermal regulation, insufficient or uneven pressure on the push spring. 

Adjustment method: The appropriate pressure and temperature should be selected according to the thickness and type of the packaging materials used. If the sealing temperature is too high, the seal will be white, and the packaging film at the seal will be easily peeled off. The pressure of each heat sealing roller is driven by the push spring. For adjustment, the temperature of the roller is controlled by the temperature controller to control the heating rod temperature. There are pressure adjustment buttons on the left and right of the horizontal sealing roller, and each adjustment button is composed of a push-pillow packaging machine button and a pull button. Using push buttons and pull buttons, there are two adjustment buttons on the horizontal sealing heat roller to prevent uneven lateral force for adjustment.
