Automated Calender machines automatically receive information from the host system, fully integrated; manual machines provide portability.

Other materials for calendering machines

When a smooth, flat surface is needed, such as cotton, linen, silk and various man-made fabrics and polymers such as vinyl and ABS polymer sheets, and to a lesser extent HDPE, calendering can also be applied to paper Outside the material, polypropylene and polystyrene.

The calender is also an important processing machine in the rubber industry, particularly the manufacture of tires, for the inner and fabric layers.

Calendering machine can also be used to polish or create evenly coated coatings on the substrate - the older use is to polish the tape, which is much faster than the web. More recently, it has been used to produce certain types of secondary batteries (such as spiral wound or prismatic lithium ion batteries) to achieve uniform thicknesses of the electrode material coating on the collector foil.

Calendering machine design

The key to the design of the two-roll open calender machine is roller structure, material selection and roller surface processing and technical parameter determination, followed by the configuration of the function. In the roller structure, we have adopted a different height of the large roller diameter in the rubber and plastic products industry, the height = (D-d) / 2, as shown in Figure 7. The purpose is to compensate for the rolling stress caused by the rolling deformation of the roll and improve the rolling part of the rolling force, forced magnetic particles to both sides of the flow, while for rolling may take different roll heating, respectively, designed for steam heating Of a hollow roll and a peripheral bore roll adapted for oil heating and water heating.

Through the production practice, the two kinds of heating methods can meet the process of roller surface temperature fluctuations in the error requirements. In the material selection, we use good wear resistance, rigidity of the alloy chilled cast iron material, roll face hardness HS72 ~ 75. But the alloy chilled cast iron roll is often due to casting defects and additives in the pellets may be on the roller surface corrosion, resulting in a short time after the use of roller surface "ice-like clouds", can not be pressed out of the smooth surface of the magnetic plate, thus It is necessary to carry out special treatment of the roller surface. Special treatment mainly has surface spray wear-resistant materials and hard chrome plating in two ways, we are using the latter.

To enhance the hard chrome and alloy chilled cast iron bonding strength, chrome before the need to first nickel, grinding processing, the thickness of the chrome layer is generally 0.05 ~ 0.08mm. It should be noted that in the production of PVC film coated with a side, the horizontal two-roll calender is best configured as a chrome-plated roller and the other is an alloy chilled cast iron roll. As the alloy chilled cast iron roll surface of the magnetic plate is relatively rough, is conducive to enhance the bonding strength of PVC film and magnetic plate.

GUANGYU Calendering machine boot steps

Calender machine boot steps：

1, open the hot oil system
2, check the roller drive to meet the operational requirements.
3, use the console, control panel or control cabinet to open the drive.
4, use the console, control panel or control cabinet to open the paper drive.
5, the transmission from the speed control, to ensure that the speed difference between the roller is correct.
6, check whether you can start drawing paper.
7, lead the paper after the lead, check the work of the scanner, and check whether the open paper control is open.
8, check whether the calendering machine can be closed.
9, press the "CLOSE" closed nip, NIP will occur after the following conditions:
A calender will load the minimum set line pressure.
B The drive is controlled by tension.
10. Press the "LOADING" button to select the calender to load. The calender load is controlled by the set value.
11, at the same time, the following checks:
A Scraper is closed and swung.
B Temperature is set correctly.
C load set correctly 1, open the hydraulic system, lubrication system
(1) Nip control: The nip can be realized by the on-site operation buttons "NIP OPEN", "NIP RELIEFE" and "NIP LOAD". When the nip is closed, press the "NIP RELIEFE" button. When the signal is no longer flashing, press the "NIP LOAD" button to load the nip.
(2) Scraper control The upper and lower scraper control is achieved through the on-site switch.
