The Method of Prolonging the Service Time of Teflon Conveyor Belt

Teflon mesh conveyor belt has the characteristics of easy ventilation of mesh, so it is widely used in textile printing and dyeing, printing and drying belt, screen printing, ultraviolet drying, UV series, light curing machine, offset printing machine, loose drying Machines, non-woven dryers, high-frequency dryers, food baking machine guide belts, temperature-controlled drying rooms, rapid drying of flux-type inks, and drying of general moisture items.


Teflon high temperature cloth has the characteristics of high temperature resistance, small friction coefficient and good insulation. It is widely used in bonding machines, clothing printing and dyeing and other machinery.


Ⅰ. The characteristics of Teflon conveyor belt


1. It is used for low temperature -70 ℃ and high temperature between 260 ℃, with weather resistance and anti-aging. After practical application, if it is placed continuously for 200 days at a high temperature of 250 °C, not only the strength will not decrease, but also the weight will not decrease;


When placed at a high temperature of 350°C for 120 hours, the weight of the Teflon conveyor belt is only reduced by about 0.6%; it can maintain the original softness at an ultra-low temperature of -180°C.


2. Teflon conveyor belt is non-adhesive: it is not easy to adhere to any substance. Easy to clean all kinds of oil stains, stains or other attachments attached to its surface; almost all sticky substances such as paste, resin, paint can be easily removed;


3. It is resistant to chemical corrosion and corrosion of strong acid, strong alkali, aqua regia and various organic solvents.


4. Teflon conveyor belt has good dimensional stability (extension coefficient less than 5‰), high strength and good mechanical properties.


5. Anti-bending fatigue, can be used for smaller wheel diameter.


6, drug resistance, non-toxic. Resistant to almost all pharmaceutical items.


7. Teflon conveyor belt is fire-retardant and flame-retardant.


8. Air permeability - air permeability of conveyor belt, reduce heat source consumption and improve drying efficiency.


Ⅱ. How to extend the service time of Teflon conveyor belt?


The claw pulley at the transition of the Teflon conveyor belt. Practice has proved that the transverse strength of the steel rope conveyor belt is insufficient. When starting, the repulsion pulley causes the conveyor belt to be overstressed locally, resulting in tearing the conveyor belt. Changing the umbrella part of the belt pulley to the belt roller can completely solve this problem. question.


Improved industrial conveyor belt drop hopper. Improving industrial conveyor belt hoppers is one of the effective measures to prevent early damage to Teflon conveyor belts. Improve the drop hopper at the transition of each belt conveyor to increase the capacity of passing foreign objects by 2.5 times, long and large foreign objects are not easy to get stuck between the funnel wall and the conveyor belt during the conveying process, and reduce the possibility of foreign objects tearing the conveyor belt. probability.


For the hopper with a large drop, a buffer baffle is installed inside to prevent the material from directly impacting the Teflon conveyor belt.
