PE Air Bubble Film Extrusion production line industry news

How is Air bubble film made with air bubble film extrusion machine?

1. Do you know how bubbles are made on bubble membranes? Maybe a lot of people have that question all the time. Now let's take a look at a lot of people like to pinch by hand bubble film is how to use the air cushion film machine to do.

First choose different kinds of resin raw materials according to the soft and hard requirements of the air bubble film, the raw material particles are inhaled into the mixer, and different kinds of raw materials are mixed evenly in a certain proportion, and then the mixed raw materials are sent to the next process through the pipeline. The raw material is put into the air cushion film machine of the extruder, and the melted raw material particles are heated at 230 degrees Celsius. The melted resin is sent to the film forming and blowing machine. Through the air bubble film machine extrusion and expansion of the film made of resin, by pulling inward at the exit of the film and injecting air, air bubble film machine will make the film into a cylindrical film, and through the injection of air can make the film thickness more uniform. The cylindrical film is then cut in two with a knife and placed on a spool. The two layers are made of a double film made by a pressure roller, which is softened by heating the film and then slowly wound over a vacuum forming roller with a round hole, where one layer is sucked up into a vacuum bubble. These rollers have holes in the round holes and are connected to a machine to extract air, and the vacuum rollers suck out the numerous bubbles in the film. These air cushion film machines produce bubble film that can be cut and bundled for packaging, and it has long been thought that the foam was caused by inflating. It was so easy to make, you can rest assured that the bubble.

2. As a buffer packaging material, how strong is the compression energy of air bubble film? We usually pinch the bubble film by hand, can not feel how strong. But someone put a stack of bubble wrap under the hydraulic press, and it was quickly crushed. The sound of bubbles bursting can be heard throughout the roll. The pressure gauge on the side showed that the pressure reached more than 70,000 kg, but when the press rose, the compressed bubble film began to expand, as if the press had no effect on it.

3. In life, many people like to pinch bubble film by hand. Why do you do this? Is it because it's fun?According to a study from western New England College in the US, squeezing bubbles can make people feel more conscious and softer, which means it can reduce stress. Like banging on the table or jigging your leg, it's the body's way of relieving stress by relaxing tense muscles.

Air bubble membrane machine types and components

Air bubble film extrusion machine through the polyethylene raw material heating, extrusion, molding, so as to produce between 600mm-3000mm single/double layer composite air bubble film products equipment. Air bubble membrane machine is mainly divided into single layer air bubble membrane machine, double layer composite air bubble membrane machine, three layers of composite air bubble membrane machine, five layers of composite air bubble membrane machine and seven layers of composite air bubble membrane machine. Various air bubble films are widely used in daily life. Bubble diameters are available in 3 sizes: 6mm, 10mm and 28mm.

Air bubble film machine is mainly composed of extruder, electric control cabinet, molding machine, tractor, coiler five parts.

1. Extruder is composed of motor, reducer, screw, barrel, net changer, mold and heater. It is mainly responsible for the melting, filtration and extrusion of raw materials.

2. The electric control cabinet is composed of temperature controller, electric material and frequency converter, which is mainly responsible for the central electric control of the whole equipment.

3. Forming machine is composed of forming roller and vacuum pump. The forming roller has 3 kinds of specifications (6mm, 10mm, 28mm), can be equipped according to customer needs. The molding machine is mainly responsible for the effective molding of the molten material extruded from the mold. It is very important to make it into air cushion film products.

4. The tractor is composed of traction roller, cutting device and film guide roller. It is mainly responsible for effective traction of air cushion film from the forming roller.

5. The coiler consists of two film reels, a rollover and a torque motor meter meter. Mainly responsible for the air cushion film on the tractor to effectively roll up the air cushion film products, and then packaging. Storage is also one of the key links of air cushion film production.

Standardize the operation and maintenance of bubble film machine

Bubble film manufacturing process: composite bubble film machine through continuous research and development, independent innovation, the company generally absorbs the world's technology, its overall design has been studied, easy to use and effective. Bubble film machine available raw materials: the equipment can be used to recycle LDPE and LLDPE plastic. The finished products can replace paper version envelope bags, paper plastic composite bags, pearl cotton and other packaging products. Environmental protection, moisture-proof, anti-extrusion molding. Used for furniture, hardware, electronic equipment, mechanical equipment, etc. How to regulate the operation of our bubble film machine, the following is a brief introduction for you:

1. Ensure that there is no problem with the automatic temperature control and the heater. Pay attention to timely adjust the heating temperature of each point within the index range.

2. Check the traction speed and control the film thickness.

3, observe the uniformity of film thickness adjustment, folding diameter is in line with the standard.

4. Check the pressure of the gas cylinder. It shouldn't be too high, but it needs extra pressure.

5. Control the ratio of raw materials and mix evenly.

6, check whether the raw materials have impurities. In particular, make sure the iron and magnet mix in time.

7. Check the position of the gear box and the lubrication of the air compressor cylinder.

8, regularly check the operation of the motor temperature rise and bubble film machine transmission.

After maintenance, what impact will the bubble film have on the later work?

1. Check the power supply, vacuum system, air pressure system and cooling system before each startup. After the device is started, check whether the rotation direction of each rotating part is correct. Usually pay attention to check the lubrication of the lubrication parts. Electrical instruments should be maintained as required.

2, the equipment should be operated by special personnel, do not let the extruder screw idle without material, so as not to scratch the screw and barrel. After shutdown, if there is material storage in the barrel, before starting again, the temperature of each temperature zone must be raised to the specified requirements according to the process requirements and kept for more than 30 minutes before starting. It is strictly forbidden to start before the temperature does not meet the requirements, so as not to damage the parts.

3, in the hopper feed, must keep clean, strictly prevent metal debris, sand and small tools into the feed mouth, so as not to damage the barrel and screw. If abnormal noise is found during operation, stop the machine immediately.
