The horizontal flow wrap machine is a kind of commonly used packaging machinery equipment at present, such as cookies, toilet paper and other commodities are all packaged by horizontal flow wrap machine. It is inevitable that there will be failures during the long-term use of the machines, we‘d better master some flow wrap machine troubleshooting methods in advance, this may help you deal with the small flow wrap machine fails as soon as possible.

(2) The filling time has been adjusted properly, but the machine malfunctions again.
Reason: The turntable of the small flow wrap machine is not fixed well, the keys and fixing screws are loose, the fixed position is incorrect or the switch inside the turntable is not functioning properly.
Solution: Fix the turntable of the flow wrap machine in the correct position and re-fix the keys and screws. Adjust the opening and closing mechanism of the switch to the correct position and fix the switch after adjustment. Additionally, when filling small particle powders, or mixtures with extremely different densities, will take longer time to fill the bag, and this may result in particles getting stuck in the sealing area. In this case, the packaging speed should be slightly slowed down to make the speed suitable for the performance of the packaged material.

◆ The electrical components of the compact flow wrap machine failure

1. The current of the heat sealing roller is too high or the fuse is blown.
Reason: There is a short circuit in the electric heater or in the heat sealing circuit.

2. The heat sealing roller is not heating up.
Reasons: 1. the electric heating wire is broken. 2. The fuse is blown. 3. There is a malfunction in temperature control, in which case the red and green lights do not flicker when setting different temperatures.

3. The temperature cannot be self-controlled, and the temperature is too high. Reasons:
● The thermocouple is in poor contact with the roller or damaged.
● There is a malfunction inside the temperature controller.

4. The photoelectric positioning of the compact flow wrap machine is not accurate.
Reasons:
● The controller's fuse is blown or there is an issue with its internal components.
● The packaging material is not installed properly, causing the tracking center to not pass through the center of the photoelectric head's aperture.
● There is dirt on the photoelectric head.
● The sensitivity knob is not adjusted properly.

◆ Failure of the compact flow wrap machine mechanism itself

1. Part of the flow wrap machine for sale mechanism cannot be started.
Reasons:
● The connection of the electric motor is broken. The broken part should be reconnected. If it is a motor malfunction, the motor should be replaced.
● The fuse is blown. It needs to be replaced with a fuse of the same ampere value.
● Gear screws and buttons are loose. Check from the motor in the order of transmission, and tighten the loose screws and buttons.
● Foreign objects have fallen into the gears and other rotating parts, causing abnormal sounds from the motor. If not deal with it timely, the motor is prone to burning out. Please remove the foreign object as soon as possible.
● Foreign objects falling onto the cutter of the compact flow wrap machine can cause the dual blades to be too tightly matched. The foreign object needs to be removed, and when removing it, the clearance should be appropriately increased if the dual blades are too tightly matched.

2. The cross sealing heat roller does not rotate
Reason1: The bearing part of the heat roller is not oiled, causing it to burn and lock.
Reason 2: The gear fixing lock ring and key are loose.
Solutions: 1. Oil should be added to the bearing part of the heat roller. 2. The gear fixing lock ring and key should be tightened again.
