Analysis of some common problems of tube filling and sealing machine( Toothpaste filling and sealing machine )

This article analyzes some common problems of the tube filling and sealing machine (not including the problems caused by the low quality of the filling and sealing machine itself). First, before analyzing specific problems, the equipment must be tested as follows:

●Check whether the actual running speed of the tube filling and sealing machine is the same as the initial debugging speed in the manual;

●Detect whether the Leicester heater is in the on position;

●Check whether the compressed air supply pressure of the equipment meets the pressure requirements when the equipment is working normally;

●Check whether the cooling water flows smoothly and whether the cooling water temperature is within the range required by the equipment;

●Check whether there is any paste falling during the filling process of the filling and sealing machine, especially to ensure that the paste will not stick to the upper part of the inner wall of the pipe;

●Do not touch anything on the inner surface of the hose, so as not to contaminate the inner surface of the hose;

●Check whether the air intake of the Leicester heater is normal;

●Detect whether the temperature detector inside the heater is in the correct position;

●Check whether the ventilation device of the heating head is working normally;

After the above preliminary inspection, we will analyze some common specific problems of the filling and sealing machine:

Phenomenon 1: When Phenomenon 1 on the left appears, it is usually caused by excessive temperature. At this time, it should be checked whether the actual temperature is the temperature required for the normal operation of the specification hose. The actual temperature on the temperature display should be relatively stable at the set temperature (the normal deviation range is between 1°C and 3°C.

Phenomenon 2: One ear phenomenon: first check whether the heating head is correctly placed in the heating head nest; then check the verticality of the heating head and the hose below. Another possible reason for the ear phenomenon on one side is the deviation of the parallelism between the two tailboards. The deviation of the parallelism of the tailboards can pass 0.2 to 0.3 mm spacers for the test.

Phenomenon 3: The sealing tail begins to crack from the middle of the hose. This phenomenon occurs because the heating head is not big enough, please replace it with a larger heating head. The standard for judging the size of the heating head is to insert the heating head into the hose, then pull it out, and feel a slight suction when pulling it out.

Phenomenon 4: "eye bags" appear under the explosion-proof line of the sealed end: this happens because the height of the air outlet of the heating head is incorrect, and it can be adjusted according to the following method.

Phenomenon 5: The middle part of the hose tail is sunken: This problem is usually because the size of the tube cup is wrong, and the hose is clamped too tightly in the tube cup. Criteria for judging the size of the tube cup: the hose should be completely clamped in the tube cup, but when the tail is clamped, the tube cup should not affect the natural change of the hose shape.

The above list are just some common tail sealing problems, the users of the filling and sealing machine must analyze and solve the specific problems according to the specific situation.
