1. The belt is torn due to impurities in the PU timing belt conveying materials. The impurities in the transported materials are mainly due to the poor coal quality of the coal port. The bulk coal and various impurities in the raw coal, such as iron and wooden rods, cause about 70-80% of the tears, thus ensuring the source coal Quality is the key to tear resistance. 2. The belt tear caused by improper installation of auxiliary equipment of PU timing belt machine. There are many auxiliary equipments for the belt conveyor. The falling of the lining board, the sharp iron absorbed by the iron remover, and the improper installation of the sweeper may cause tearing and scraping of the conveyor belt. The ordinary conveyor belt has no lateral protection structure and cannot prevent tearing. 3. The belt conveyor is torn due to imperfect structure. Due to the imperfect structure of the belt conveyor, the falling point of the conveyor belt is large, the relative velocity of the impurities in the coal flow is large, the impact force is large, and the sharp and hard extra-long impurities are easily inserted into the conveyor belt at the falling point, causing The conveyor belt is torn. 4. The conveyor belt is torn due to blocking. The transfer chute is small, which is easy to hinder the passage of materials and impurities and cause the conveyor belt to tear. 5. The deviation of the PU timing belt caused a torn edge. 6. Coiled coal on the return trip. In addition, the aging of the PU timing belt joint edge glue makes the core layer of the conveyor belt enter the water, causing the steel rope to be corroded and pulled out, which can also cause tearing.
Foshan Uliflex Transmission Technology Co., Ltd. (Uliflex Industrial Belt) participated in the 2026 China International Elevator Exhibition from May 20 to 23, 2026 at the Canton Fair Complex in Guangzhou, China. Yangzhou P&B Transmission Technology Co., Ltd., which belongs to the same group as us, also participated in this exhibition.
Uliflex industrial belts will participate in the 2026 World Elevator & Escalator Expo from May 20th to 23rd at the Guangzhou Canton Fair Complex. At this exhibition, Uliflex Industrial Belt will bring a variety of Uliflex's latest developed new elevator traction steel belt products for customers from various countries to visit and exchange.
Uliflex had productive business exchanges with people from different countries and regions at the 35th China International Glass Industry Technology Exhibition, allowing Uliflex to gain a deeper understanding of the development trends and trends of the glass production industry in 2026
Uliflex has started the process of localization of polyurethane industrial belts in China since the mid-1990s. It is one of the first enterprises to establish industrial belt production lines in Chinese Mainland. From improving production equipment to independently developing new molds and exploring more effective production processes, after the passage of time, the entire polyurethane industrial belt production process has been connected.
Uliflex will participate in the 35th China International Glass Industry Technology Exhibition at the Shanghai New International Expo Center from April 7 to 10, 2026. We sincerely invite customers and peers from all over the world to gather in Shanghai for business exchanges and discussions on indust
Based on 25 years of experience in industrial belt production, Uliflex Industial Belt has drawn this conclusion: Typical faults of synchronous belt drives mainly include fatigue fracture, belt tooth wear and shear, belt deviation and unilateral wear, skipped teeth, and abnormal noise. These faults directly affect the stability and lifespan of equipment operation. Let's analyze the causes of various classic synchronous belt drive faults one by one:
Many timing belt users have likely encountered the issue of belt tooth jumping. If this problem occurs frequently, production workshops have to shut down for inspections, significantly affecting the efficiency of enterprise production. Based on over 20 years of experience in timing belt manufacturin
In numerous fields such as automation equipment and precision machinery, timing belts have become core transmission components due to their advantages of precise transmission, low noise, and high efficiency. However, their tooth-skipping failure has always been a concern for industry practitioners.
