CEMA Galvanized Painting Rubber Conveyor Rollers For Electronic
Belt Conveyor
Conveyor Belts Scales Roller For Electronic Belt Scale Conveyor
The roller is an important part of the belt conveyor, and its
function is to support the weight of the conveyor belt and the
material. There are many types of rollers. Next, Tianyu will
introduce you to the types of rollers.
According to its structure, the rollers can be divided into
parallel rollers, buffer rollers, spiral rollers, self-aligning
rollers and trough rollers, etc. According to their materials, they
can be divided into polymer rollers, steel rollers and ceramic
rollers. class. Among them, parallel rollers include ordinary type,
comb type, forward tilt type, steel rubber type, spiral type, etc.;
buffer rollers include spring plate type, buffer ring type, strong
buffer type, adjustable elastic type, hanging type, etc.;
adjustment The core roller has general type, friction reversible
type, strong type, cone type, spiral type, combined type, etc.;
grooved roller has ordinary type, forward tilt type, quick-change
bearing type, hanging type, variable groove angle type, etc.
Transition type, V type, etc.
Impact roller temperature protection
When the belt conveyor roller and the belt friction cause the
temperature to exceed the limit, the detection device installed
close to the roller sends out an over-temperature signal. After the
receiver receives the signal, a 3s delay will cause some actions to
be performed, the motor power supply is cut off, and the conveyor
automatically Stopping, play a role in temperature protection.
Speed protection of roller group
If the conveyor fails, such as the motor is burned, the mechanical
transmission part is damaged, the belt or chain is broken, the belt
slips, etc., the magnetic switch in the accident sensor SG
installed on the driven part of the conveyor cannot be closed or
cannot be closed at normal speed At this time, the control system
will function after a certain delay according to the inverse time
limit characteristic, and the speed protection circuit will take
effect to execute some actions and cut off the power supply of the
motor to avoid the expansion of the accident.
Impact roller coal bunker coal level protection
There are two high and low coal level electrodes in the coal
bunker. When the coal bunker cannot cleave coal because there is no
empty car, the coal level will gradually increase. When the coal
level rises to the high level electrode, the coal level protection
will start from the first belt conveyor. , Each conveyor stops in
turn due to coal piled at the tail.

Advantages of the tapered roller:
1. The mass of some rotating parts is reduced by 1/3, and the
moment of inertia is greatly reduced;
2. The production process is simplified, the labor intensity is
reduced, and the work speed is increased;
3. The old-fashioned sealing structure has been changed, and the
normal operation without pollution has been completed for a long
time in various harsh environments;
4. The coaxiality of the bearing positions at both ends of the
idler roller is measured, and the error is ≤0.05mm;
5. The interference pressing of the bearing seat and the support
ring can reduce the out-of-roundness of the steel pipe by about
60%, and the radial runout of the outer circle is ≤0.3mm;
6. Rotation resistance≤1N;
7. Noise (under 1000r/min) ≤30dB;
8. The manufacturing precision of the idler is used, and the
assembly pass rate is good.
