To supply the service life of that hot press, we need to regularly maintain and maintain the particular hot press, and often thoroughly clean the hot press. To clear the hot press, we need to pay attention to the following areas:
1. The staff needs being cleaned up before cleaning.
TWO. Turn off the power before cleaning.
3. The hot pressing web should be cleaned to extend the assistance life.
4. Clean up and check whether the web link is normal and whether you can find any oil leakage.
5. Check if you have any abnormality before starting the operation every single day.

Precautions for selecting a constant flat pressure hot press
Since the start of the 21st century, the pace connected with developing continuous flat-press hot presses has accelerated in China. After not too long of production practice, the effectiveness of domestic continuous flat-press scorching presses has reached the intercontinental advanced level. The continuous flat pressure output line has obvious advantages in producing MDF using a thickness of 4~15 mm.
????Whenever selecting a continuous flat pressure hot press, you should focus on:
????(1) According to the main direction with the enterprise product, the main parameters on the press should be determined. The production line of the main production sheet really should be a shorter press length plus a faster production speed; the presses with medium and thick plates needs to be compared. The length of your press is relatively low, plus the production speed is relatively lower. It is not required to require a press to produce a plate which includes a thickness of 2 to 35 mm. The width of the press need to be selected from 4' to 9' in accordance with the specifications of the product or service.
????(2) The structure of the inlet platen belonging to the continuous flat press is really critical. Although the pre-press includes compacted the slab, there continues to be air in the slab, along with the slab is exhausted so the slab is not vented. The tiny fiber mass is caused to fall for the steel strip, which requires a unique press plate inlet structure. Imported presses have their very own patented technology to solve this problem, and domestic presses also have their particular patented technology. For example, the Shanghai plate machine endless press adopts the flexible adjustment technology from the inlet bending platen, which can automatically adjust the opening penetration of the inlet and the curved surface in the platen according to the thickness detection data on the pre-pressed slab. The supporting hydraulic procedure adopts the servo control technique, and the technology is very advanced. Yalian Machinery's continuous press uses a very flexible inlet structure and constant pressure hot plate for the production of thin and lower density sheets.
????(3) According for the requirements of the hot annoying curve, the frame and this oil cylinder are divided in to several sections, and each section includes a set of thermal oil this circulation system, and each technique are designed according to the home heating requirement. The first and second portions are high temperature and high pressure sections, which are the sections using the most heat consumption during an entire pressing process. Therefore, the design on the secondary circulation system of this section should fully find the requirements of different plate types and different specifications belonging to the pressing process. The suppression of special plates as well as increase in production leave some heat supply.
????(4) The structure of the chain plus the roller rod and the bolt is vital. It must be reliable plus easy to disassemble and swap. The cleaning and lubrication system directly affects the service life with the roller rod and the bolt. The particular bolt structure of Yalian Equipment has advanced technology. Reliable use is a company's patented technology.
????(5) The hydraulic system with the cylinder can adopt the proportional valve system as well as the open-close valve system, each that has its own characteristics, nonetheless it is better to use the proportional valve system within the high pressure section and the actual opening and closing valve process in other areas.
????(6) The press belt is an important and valuable wearing part. Although press designer considers a group of measures to protect the metallic strip, it will cause damage as a result of various reasons during its surgery. In addition to the servicing and operation level, the life belonging to the steel strip depends on the specifications from the products that are often generated. The long-term high-speed production of thin sheets enhances the possibility of damage to the particular steel strip. The smoothness on the steel strip on the continuous flat-press hot press directly affects the surface from the sheet, especially when producing calenders (non-sanded sheets), double-polished steel strips really should be selected. The thickness of the iron strip is determined by along the press. The author believes that the thickness of the steel strip isn't as thick as possible. The actual thicker the steel strip, the larger the diameter on the drive roller, otherwise the time for fatigue cracking will probably be advanced, and the service life in the steel strip will be sophisticated. It will be shortened, so the thickness of the steel strip used under along the press is 2. 7mm.
????(7) The pressure from the continuous flat press is increased. When using the heat move oil, try to choose a reliable synthetic heat transfer oil, and usually do not use mineral heat transfer essential oil.
????(8) Pay attention to the design of the upper steel strip return seal cover. The cover not only has the protection function, your closed waste steam, but also the heat preservation function. The lower the return temperature with the steel strip is, the far better.
