When using the blowing machine, be aware of which problems

Three-tier co-extrusion blown film machine, compared with similar equipment has a higher yield, plasticizing good products, low energy consumption, the advantages of simple operation, completely solve the film falbala and winding size top problem, make the product quality on a new step. The produced films have high transparency, puncture, high toughness, low temperature, good compound fastness, and crimp resistance. This membrane is good for its obstructing, preservation, moisture-proof, frost proof, oxygen resistant, oil resistant, can be widely used in weight packaging. If all kinds of fresh fruit, meat, pickles, fresh milk, liquid beverage, medical supplies, etc.

There are some problems to be noticed in the operation of the dalian film blowing machine.

1. The die head and die cleaning can only be used to clean the mold mouth, and can not be used to wipe off the die with blade or iron blade, otherwise it will cause damage to the die.

2. Check whether there is any wet material when the raw material is unpacked, and the wet material must not be mixed. It must be dried in the drying room before it can be used.

3. The equipment shall not start extruder and rotary die head without heating, heating temperature and time, otherwise it will damage the equipment.

4. No corona treatment or corona treatment does not reach 38 dyne film, which cannot be put into the finished product. Otherwise, it will cause a serious accident of compound quality.

5. Blow molding machine guide roller, including rubber roller and roll rollers, shall not be cut with the blade, otherwise it will cause the cutting of the guide roller.

6, the filter on the extruder and corona processor must be replaced periodically filtering and cleaning, general requirements must be replaced within 24 hours to 48 hours filter and the silicon roller clean with alcohol corona processor. The specification of filter screen: for the second layer 80 eyes, a layer of 100 purpose three layers of filter screen.

7. The corona processor guide roller does not have the film to move around and must not turn on the corona processor. Once the film is broken or down, the corona processor should be turned off urgently, so that the corona processor will not burn.

In the process of heating 3 to 4 hours, it is necessary to check whether the normal and voltage current meter of each heating part is normal. Starts, the host at a speed of 15 to 20 RPM boot, observing the situation of material plastication, the pressure of the host, current is normal, it is forbidden to heat to forcibly boot (such as heating is not enough to lead to mold dislocation and film thickness). In the production process, the operator must not stay away from the rewinding part, prevent the accident from finding and handling in time, pay attention to the position of the knife and hand when collecting the volume, and make safety first.

When cleaning the membrane mouth and changing the net, wear protective gloves, and notice that the parts of the terminal are exposed and avoid electrical breakdown. Cleaning membrane mouth and change the screen must be used when copper shovel, in order to avoid injury and membrane mouth and change the screen, at the same time when the outage of net pay attention to efficiency, the grasp of time, temperature is unfavorable to avoid affecting blown film work next time. Be careful not to pull the handle into the roll during the startup process. Shut down power and air pump immediately after shutdown.
