Guidelines for self-tracking conveyor belts when fabricating PVC or PU conveyors

Except for a number of conveyor lines where the wheels have the effect of locating against the screen (also known as deflection) such as plastic conveyor, chain conveyor …, there are many lines of conveyors such as PVC conveyor, PU conveyor, belt rubber conveyor … is very often screened, especially in the design of long conveyor belt, narrow belt and two-way conveyor belt.

 

One of the methods that you often think of when designing conveyors is to glue the straps positioned at the bottom of the belt like PVC conveyor. It is the most common method, but when the conveyor is long, the large belt sieving force presses on the positioning groove of the roller, it cracks tendons, breaks tendons, breaks guide tendons. In this case, it is often necessary to remove the PVC conveyor belt, glue the ribs, or replace the new wire. PVC conveyor belt life is therefore much lower than the actual life we ​​would be using PVC conveyor.

Viet Phat Conveyor Belt offers you a better, more durable and more convenient anti-sieve method. It is pressed the anti-sieve positioner on the top of the PVC conveyor belt, and positioned the belt by a pair of two ribbed clamping rollers locating the lower surface of the conveyor belt.

 

This method is only available when the upper conveyor surface application does not require absolute flatness. As is the case with the conveyor belt shown in the picture above, which was designed by Viet Phat Conveyor, the three independent chains of conveyor belts that assemble the machine components do not need to be completely flat, allowing the upper surface of the conveyor to be attached to the positioning ribs, and thanks to so there is no need to cut the positioning groove on the drum shaft.

 

Figure 1 below is the top of the conveyor belt, the thermoforming of the positioning rib. The white PVC conveyor belt is rough underneath, no need to press the ribs, the surface is very good at friction.

Figure 2 below shows the underside of PVC conveyor belt. Viet Phat Conveyor Belt is designed against the screen by a pair of rollers supporting the return road. Every road must manufacture rollers to support the back-way runway. Viet Phat Conveyors design a pair of wire support rollers, and at the same time clamp the belt to guide the conveyor.

On the underside of PVC conveyor belts, Viet Phat Conveyors are designed to support rollers in pairs, both supporting the wire and clamping the position against the screen for the conveyor belt.

This method of design does a double job. Easy to fabricate, reduced cost, much more efficient than traditional method of slitting on drum. Reason: a conveyor belt usually only has two two-headed drums to cut the groove. With many long conveyor designs, two drums are not strong enough to resist the belt screen. With this method, each roller supporting the conveyor belt has the effect of locating against the belt screen. With the design of the wire support roller distance from 700mm to 1000mm, no matter how long your PVC conveyor belt, one-way or two-way running, wide or narrow conveyor belt, you can 100% eliminate the worry of sieving when designing PVC or PU conveyors.
