Below I will talk about the common failure of particle packaging machine, the causes and solutions.
1. Fault of horizontal sealing hot roller: bad sealing.
Causes: poor thermal regulation, insufficient push spring pressure or uneven pressure.
Solution: 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 is easy to peel off. The pressure of each hot sealing roller is adjusted by push spring, and the temperature of the roller is controlled by temperature controller to heat the heating bar. About horizontal sealing roller is equipped with pressure adjusting knob, every adjustment knob and consists of driving pillow packaging machine button and pull button, if using just push the button to put stress on hot roll, easy to cause bad sealing, so should be appropriate use of push button and the knob, transverse seal hot roller two sets adjust knob is adjusted in order to prevent the transverse uneven when used.
Second, the electromagnet does not attract
Reason: this kind of fault is mainly caused by the internal fault of the main engine, electromagnet coil burning, circuit interruption and other reasons. The solution is: first check the host internal or external problems; Second, check the safety tube of the electromagnet, check whether the electromagnet has power signs, eliminate the mechanical resistance, in the case of all normal detection of the internal power supply. 2. In weighing and packaging machine, the electromagnet often fails to close, which is caused by: sensor damage, supply bridge voltage fault, wrong line connection or interruption.
The solution is: to detect the load signal of sensors and wires or the host, and then to detect the bridge and amplifier circuit or computer output display circuit.
Three, the rotary table position fault
(1) the packaging material is mixed into the heat sealing part.
Reason 1: the bagging time is not coordinated with the heat sealing time
Solution: the gear connected with the turntable is the two-gear, push the two-gear up, change the engagement, so that its material does not fall when sealing, the ideal time is the lateral sealing after the completion of particles into the bag, adjust properly do not change easily.
Reason 2: packaging speed is too fast, material landing time is too long.
(2) the cutting time has been adjusted and is abnormal again.
Cause: the rotary disc is not fixed properly, the key and the fixing screw are loose, or the fixed position is not right, the opening and closing device in the rotary disc is not open and closing properly.
Repair and adjustment: fix the turntable in the correct position of pillow packing machine, and fix the key and screw again. Adjust the opening and closing mechanism of the opener to the correct position and then fix the opener. In addition, it takes a long time to pack a small powder or a mixture with a very different specific gravity, thus causing the powder particles to bite into the sealing part. At this time, the packaging speed should be slightly slowed down, so that the revolution should be suitable for the performance of the packed material.
