1. Before starting the hardware packaging machine, check whether the specifications of the installed container and bag maker meet the requirements.
2. Pull the main motor belt by hand to see if the machine runs flexibly. After confirming that there is no abnormality, the machine can be powered on.
3. Under the machine, install the packaging material between the two paper stop wheels, and place it in the groove of the paper support arm board of the machine. The paper stop wheel should clamp the core of the loaded material, so that the packaging material is aligned with the bag maker. , and then tighten the knob on the cover, and ensure that the printed side is facing forward or the composite side (ie, the polyethylene side) is facing back. After the machine is turned on, adjust the axial position of the packaging material on the paper roller according to the feeding situation to ensure normal paper feeding.
4. Turn on the main power switch of the hardware packaging machine, press the clutch handle to separate the metering mechanism from the main drive, turn on the start switch, and the machine runs idly.
5. If the conveyor belt rotates clockwise, it should be stopped immediately. At this time, the main motor is reversed. After the motor is reversed, the belt rotates counterclockwise.
6. Set the temperature. According to the packaging materials used, set the heat sealing temperature on the temperature controller of the electric control box.
7. Adjustment of bag length Put the packaging material into the bag maker according to relevant regulations, clamp it between two rollers, turn the roller, and pull the packaging material below the cutter. After reaching the set temperature for 2 minutes, turn on the start switch. Loosen the lock nut of the bag length adjusting screw, adjust the hand button of the bag length controller, turn clockwise to shorten the bag length, and vice versa. After reaching the required bag length, tighten the nut.
8. Determine the position of the cutter, remove the cutter when the bag length is determined, turn on the start switch to seal several bags continuously, stop immediately when the heat sealer is just opened and the roller has not pulled the bag. Then move the left cutter first, so that the knife edge is aligned with the middle of the horizontal seal with an integer multiple of the bag length (usually 2 to 3 times the bag length), and make the blade perpendicular to the direction of the straight paper, tighten the left cutter fastening screw, Put the right cutter against the left cutter, let the tip of the cutter face the tip of the cutter, slightly tighten the fastening screw in front of the stone cutter, and press the back of the right cutter down to make a certain pressure between the two cutters , Tighten the fastening screw behind the right cutter, put the packaging material between the blades, knock down the front of the right cutter slightly to see if the packaging material can be cut, otherwise it should continue until it can be cut, and finally Tighten the front screws.
