2. The internal cooling directly passes through the film bubble to dissipate heat to achieve the purpose of cooling. Because the flow rate of the air in the bubble is relatively low and has no regularity, external cooling is more dominant. In the blowing process of the film blowing machine, in order to ensure the quality of the film product, the stability of the bubble before the film is formed must be considered, so that the qualified rate of the product can be effectively controlled. The output of blown film of the film blowing machine is not only restricted by the film bubble, but also the cooling system of the film blowing machine. A complete cooling system requires reasonable configuration and stability of the film blowing machine.

Daily inspection and maintenance of film blowing machine:

1. Check whether the temperature automatic control is intact, whether the heating appliances are intact, and pay attention to timely adjust the heating temperature of each node within the index range.

3. Observe and adjust the uniformity of the film thickness, and the folding diameter meets the standard.

5. Check and control the ratio of raw materials and mix them evenly.

7. Check the lubrication of the gearbox position and the air compressor cylinder.

8. Regularly check the temperature rise and mechanical transmission of each running motor.

Abbreviation for open mixing mill. A rubber mixing machine with exposed rollers used in the rubber factory to prepare plastic rubber, compound rubber, or perform heat refining and molding.

The main working parts are two hollow rollers or drilled rollers that rotate in different directions. The front roller is installed on the operator side. It can be moved back and forth horizontally by manual or electric action to adjust the roller.To meet the operating requirements, the rear roller is fixed and cannot be moved forwards and backwards. The two rollers are generally the same in size, and each rotates at different speeds. The raw rubber or rubber material is rolled into two with the rotation of the rollers.The gap between the rods is subjected to strong shearing to achieve the purpose of plasticizing or mixing. open mixing mill are also used in plastics processing and other sectors.

The open mixing mill is the abbreviation of the open rubber mixing machine. In plastic products factories, people are used to calling it a two-roll machine. The open mixing mill is before the calender and after the mixer, and the function is to mix the raw materials uniformly.It is mixed and plasticized to provide a more uniformly mixed molten material for the calendering of plastic products. When producing cables, the mill can directly smelt the powdery materials mixed according to the formula into a melt. The molten material is then calendered into a sheet-like belt, and the pelletizer is cut into granules. On the floor production line, it can directly provide the fabric leather with a uniformly mixed and plasticized primer, and it can also use recycled waste plastic film

Re-plasticize and re-process on the open mixing mill.

Preparatory work before the operation of the lab two roll millIn

 the rubber mixing process, the lab two roll mill machine is an indispensable equipment, During the operation, Attention should be paid to the safety of the lab two roll mill machine.

1.Before starting the open mixing mill,you must check the circuit (current and voltage,etc.) and check whether there is any residual material two roll mixing mill.

2.Wear cloth gloves (depending on the properties of the material).The kneading operation absolutely avoids waist tethers, belts, rubber, etc. 

3.Every time you start the lab two roll mill machine, you must test the emergency braking device to check whether the braking is sensitive and reliable( it it is a knee-type device, you must be used to contact your knees with the with the braking device),It is strictly prohibited to use the emergency braking device during normal operation.

4.The rubber material should also be inspected before feeding,If there are hard metal impurities mixed with the rubber, it will be put into the laboratory roll mill,resulting in a sudden increase in lateral pressure, which will cause equipment damage.(There must be no hard objects in the added materials, such as iron, sand, etc.)

5.First of all,It is necessary to adjust the roll distance of the lab two roll mill to maintain the balance of the roll distance.If the rollers at both ends have different adjustments, The rollers will be eccentrically loaded and the equipment will be easily damaged.This is strictly prohibited.
