<p>With the automation process, all kinds of <a href="https://www.smartweighpack.com/packing-system" target="_blank">packaging machines</a> come into our sight. The packaging machines are not only safe and sanitary, but also can greatly save labor costs, and the efficiency is faster than manual labor. But the machine will face the problem of failure. In this article, Shanghai Songjing will introduce solutions to common failures of packaging machines.</p><p><br></p><p><img src="https://img.weyesimg.com/p/p21/198_0.jpg?imageView2/2/w/940/q/75" alt="Quantitative packing weigher Modular Linear Weigher milk powder granule sugar linear weighing machine"></p><p><br></p><p><strong>1. Partial failure of film guide groove:</strong></p><p><br></p><p><br></p><p>The film cannot bite into the upper pillow packaging machine heat roller, or leave the heat roller or the ends are not aligned.</p><p><br></p><p><br></p><p>Reason 1: The center of the film, guide groove, longitudinal sealing roller and horizontal sealing roller are not in a straight line.</p><p><br></p><p><br></p><p>Reason 2: The film guide groove is too inclined.</p><p><br></p><p><br></p><p>Reason 3: The speed of the eccentric sprocket of the horizontal sealing heat roller is abnormal.</p><p><br></p><p><br></p><p>Adjustment method 1: Roll the upper adjustment knob of the vertical sealing pillow packaging machine and turn it to the right, increase the pressure, and the film thickness will be stretched. It should be noted that if the stretch is too large, the seal cannot be sealed.</p><p><br></p><p><br></p><p>Adjustment method 2: Reduce the pressure of the longitudinal heat sealing roller. If the pressure is too high, the film cannot be clamped in, and it may be extruded.</p><p><br></p><p><br></p><p>Adjustment method 3: The vertical sealing roller clamps more than usual, generally 10MM should be clamped at 7MM.</p><p><br></p><p><br></p><p>Adjustment method four: Adjust through the pillow packaging machine. If the two ends are still uneven, bend the guide groove on the side of the film to bend inward.</p><p><br></p><p><br></p><p>Adjustment method five: The center line of the film guide groove has an error, and it should be replaced if it is defective.</p><p><br></p><p><br></p><p><br></p><p><strong>2. The cutting position is faulty.</strong></p><p><br></p><p><br></p><p>(1) The film cannot be cut:</p><p><br></p><p><br></p><p>Reason 1: The gap between the movable knife and the fixed knife is not well adjusted.</p><p><br></p><p><br></p><p>Adjustment method: There are two short tension screws on the outside of the fixed knife, and two long compression 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 sharpening of the two knives. The gap between the blades of the two <a href="https://www.smartweighpack.com/" rel="noopener noreferrer" target="_blank"><strong>pillow packaging machine</strong></a> is preferably 1/100MM, and the two blades can be slightly contacted, so that the sharp knives are always parallel. When adjusting, the film is clamped and cut by hand while adjusting. When adjusting, the cutter clutch should be disengaged.</p><p><br></p><p><br></p><p>Reason 2: If the cutting blade is damaged, use oilstone to grind it, and use a grinder to repair it.</p><p><br></p><p><br></p><p>Reason three: poor installation of the cutter, poor clutch clutch of the cutter, and disconnection of the positioning key.</p><p><br></p><p><br></p><p>Solution: Check all parts carefully and tighten again.</p><p><br></p><p><br></p><p>3. Failure of horizontal sealing heat roller: poor sealing.</p><p><br></p><p><br></p><p>Cause: Poor thermal regulation, insufficient or uneven pressure of the push spring.</p><p><br></p><p><br></p><p>Adjustment method: The appropriate pressure and temperature should be selected according to the thickness and type of packaging materials used. If the sealing temperature is too high, the seal will be white, and the packaging film at the seal will be easy to peel off. The pressure of each heat-sealing roller depends on the push spring. For adjustment, the temperature of the roller is controlled by a temperature controller to control the heating temperature of the heating rod. 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 <a href="https://www.smartweighpack.com/" rel="noopener noreferrer" target="_blank"><strong>packaging machine</strong></a> button and a pull button. If only the push button is used, excessive pressure will be applied to the heat roller, which may cause poor sealing, so it should be appropriate Push buttons and pull buttons are used, and two adjustment buttons are provided on the horizontal sealing heat roller to prevent uneven lateral force for adjustment.</p>
