Fully -automatic membrane machines are mainly used in the product packaging industry in our daily life, especially in the printing industry.How to overwriting the filmmaker before operation? What are the functions and characteristics of the automatic membrane machine? Lets take a look.
How to overwriting the membrane before the operation of the membrane machine
1. Tear the corner of the sample of the film to tear in the width direction. Press and hold the paper. After the width direction is torn away, it is torn all after the width direction.Moving to the film, it means that the printing of the print and the film is well bonded, which is a qualified product.
2. Put the samples with good membranes in the baked channel and bake for about 30 minutes with 60 ~ 65 degrees Celsius.After baking, the film should not be separated from the paper.
3. Put the sample in cold water for 1 hour and take it out. If the plastic film and the print are not separated, it is a qualified product.
4. Press the sample on the indentation machine.In summary, after the membrane samples pass one or more test methods, they can be put into mass production.If it does not meet the requirements, the sample is not qualified, and the compression adjustment process is tested, knowing that the inspection is qualified.
What are the characteristics of the membrane machine function
The functions and characteristics of its fully automatic film covering machine are mainly the following points:
1. Automatic paper delivery machine: Feidas precise design of paper heads can be sent out steadily. Using segmented transmission devices, automatic edge control is installed to adapt to different paper for paper.The precise limelight, which is convenient to adjust the limelight in the relative position of the paper pile during operation.Unique non -stop paper renewal device, that is, it is equipped with auxiliary platform, which can make paper supplements while sending paper to ensure that production is continuously carried out.
2. Divopy device (optional combination): The two -level powder removal structure of the powder sweeping and pressure powder is adopted.After the pressure roller goes out, it effectively removes the dust sprayed by the paper surface in the printing; the tight arrangement design of the conveyor belt combines efficient wind absorption so that the paper will not abdicate or misalignment, so that the paper is accurately delivered to the host pressure part.
3. The inner electric heating system and automatic temperature control device of the hard chromium composite roller of the host make the temperature distribution evenly.Increased composite roller design to increase the pressure bumper surface: the diameter of the electric heating roller is 420mm, and the inner wall of the roller core is round, so that the roller is not biased and the heating surface is uniform;Operation.Hand -type hydraulic cylinder controls the composite pressure, which can make the upper and lower rolls on the left and right pressure balance.High -precision hard chromium heating rollers are matched with high -performance pressure -blending rubber rollers to perfectly realize the heat -re -membrane process.
Failure to eliminate a membrane machine
1. The machine does not start: the input wire is not connected, the power cord is connected, and the voltage is not enough.
2. Inaccurate temperature measurement: thermocouple, temperature control meter. Whether it is installed correctly and damaged.
3. The vacuum of the work is not available: the air path is not connected, the hand valve or solenoid valve is not closed, the vacuum pump motor belt is loose, and the vacuum table is damaged.
4. Total power switch jumper: The heating box top input electric leakage, the power distribution box leakage, the external wires are set on the device, the motor leakage, etc.
5. Insufficient diaphragm: Insufficient vacuum, leakage, insufficient temperature, the membrane too thin, the workpiece has pasted other materials, the depth of the workpiece exceeds the pull of the membrane, the suction time is too short, the membrane does not rise, the workpiece distance is not pulled, the distance of the workpiece distanceToo close.
