Analysis of conveyor belt characteristics (2)

The special conveyor belts of Fuli brand tile line provide reliable guarantees for the flexibility from the selection of raw materials to the reasonable weaving structure. The bendable radius is: medium-speed belt R75mm, high-speed belt R50mm, and acupuncture belt R70mm, ensuring the conveyor belt in each A variety of models, different widths, and different vehicle speeds can be smoothly and smoothly operated on the production line. Fuli Brand's high-speed driving flexibility is better. It has been proved by the industry users for many years that this belt has only low sound in the high-speed operation of 180m/min. The high-speed mute belt thus gets its name.
3, breathability: After the rubberized single-sided corrugated cardboard with the conveyor belt into the double-sided machine synchronously for bonding, compounding, drying, the cardboard in the cornstarch adhesive at a temperature of 170 °C and the strip body itself 60- The paperboard is gelatinized, bonded and dried at a temperature of 70°C in both directions.
The Fuli brand conveyor belt has a good air permeability of 202m3/cm2min to ensure that the dried corrugated board has low moisture content, high stiffness and high peel strength.
With its reliable comprehensive quality and breathability, Fuli brand conveyor belt can meet the high-speed operation of tile line 1.50m-180m/min and ensure the production of qualified cardboard.
The determination of the air permeability data is based on the theoretical scientific rationality, the reliability of the applied practice, and the verification of the paper board quality. The air permeability is not too low and not too large, and the air permeability is too large to cause heat loss and the conveyor belt is reduced. The moisturizing properties.
4. Insulation property Due to the change and difference in the thickness of various types of corrugated production board (3 layers, 5 layers, 7 layers), when the Veneton board is dried by a double-sided machine heating plate, the lower surface of the board (bearing the heating board On one side, the temperature is transmitted to the other side of the board through the board thickness (on the side of the belt), which is originally in the thickness of the board (especially the thicker 5-layer and 7-layer board), resulting in a certain temperature difference between the upper and lower sides of the corrugated board. In order to reduce the temperature difference between the two sides and ensure the gelatinization temperature (above 60°C) required for the adhesive in the cardboard, this requires the conveyor belt itself to be maintained at a certain temperature (about 70°C) to be compensated in order to make the cardboard thicker on both sides. All get the best adhesion and drying effect. The conveyor belt keeps warm and breathable, both of which cannot be neglected.
5. Dimensional stability: In the course of running, the conveyor belt tends to have different degrees of dimensional change, that is, the length of the belt gradually stretches, and the width of the belt gradually shrinks and narrows. The special conveyor belt for the tile line is a multi-layer fabric, although it has a high Intensity, but the phenomenon of micro extension and shrinkage under the continuous action of strong force and high temperature is theoretically normal and allowable, but this change in length and width should be limited and limited. The length and width of the tape after stretching and shrinking must be stable within the scope of meeting the cardboard production process requirements. If the length of the stretched belt exceeds the adjustable range of the tensioning device, the fitment between the belt and the driving roller is too loose, resulting in insufficient friction and slippage, which affects the normal operation of the conveying belt. If the contracted bandwidth is less than the width of the production board (ie, the maximum width of the board that the production line can produce), the conveyor cannot cover the full width of the board, leaving the edges of the board exposed and debonded. Therefore, the width of the conveyor belts fitted for each type of tile line must be 60mm-80mm more than the maximum width of the machine for the production of cardboard, so as to ensure that the contracted conveyor belt can still cover the entire web (after shrinking, the bandwidth is better than paper. The width of 20mm is the minimum value).
Fuli brand tile line special belt from the raw material to the production of goods through the physical stereotypes and chemical styling agent special treatment, so that the conveyor belt longitudinal elongation and transverse shrinkage are controlled to the minimum (elongation rate of 4%, shrinkage rate of 1.8%), To ensure the stability of the entire length and width dimensions. According to this, the special ribbons for the Fuli brand tiles are also called non-elastic bands in a certain sense.
Third, concluding remarks Quality is the root of an enterprise's survival and is the basis of its credibility.
Fuli brand tile line special conveyor belt not only wins the common trust of all carton manufacturers in China, but also attracts many foreign and joint venture users who have imported foreign high-speed production lines (US, Italy, Japan, South Korea, and Taiwan) for their unique performance and quality advantages. , such as: Shanghai Jifeng, Shanghai Shengbao, Shanghai Zhongyu, Shanghai Jiakang, Shanghai Jiehua, Guangzhou Yangcheng, Shenzhen Huali, Shenzhen Shunfeng, Shenzhen Huahong, Dongguan Liwen, Dongguan Zhenxing, Fuzhou cartons, Xiamen Baoyin, Suzhou Longbang, Suzhou Shengbai, Nanjing Shengbai, Baoding Shengbai, Zhuji Shangfeng, Ningbo Paper Products, Chongqing White Cat, Chongqing Dingyi, Shenyang Topside and many other large-scale enterprise users are numerous.
