Installation and adjustment of mesh belt conveyor and adjustment of tension

Mesh belt conveyors rely on its load-bearing and transparent characteristics. In addition to conveying in the natural environment, they are widely used in large dryer lines and cleaning lines. The basic function of a mesh belt conveyor is transportation. It is unique in that it can complete the transportation in a high temperature, high humidity, and high corrosion environment. This is the characteristics and advantages of the mesh belt conveyor, and it is a job that other conveyors cannot complete. The permeability of the mesh belt conveyor can complete the rapid cooling or drying of high-temperature or high-humidity materials during transportation (drying requires a heat source, otherwise it is only natural moisture discharge), which is also the main reason for its matching on drying equipment.
The normality of the tension of the mesh belt conveyor directly affects the use effect and service life of the conveyor. If the tension is too loose, the chain will lose teeth or jump teeth, and the tension is too tight, which will affect the life of the mesh belt chain. Can't even turn or when the mesh belt jumps up and down.
Adjusting the tension of the mesh belt conveyor is divided into three steps: First, adjust the parallelism of the drive shaft and the passive shaft (because the parallelism is not reached will cause the belt conveyor to run off and skip teeth on one side) and then drive the bearing 3. Fix the sprocket and adjust the center distance of the sprocket. The passive end is tensioned in parallel from loose to tight sides. At this time, the lower mesh belt is supported vertically by hand until the chain is 50mm higher than the lower track. Finally, the passive end bearing and the tension bolt can be fixed.
The correct installation and commissioning of the mesh belt conveyor during the initial operation is of great significance for evaluating the quality of the mesh belt conveyor. Generally speaking, the mesh belt conveyor must first be equipped with accurate power for operation. Vibration or noise will occur when the power is low. It may even cause the motor to burn out under long-term overload operation, and the power will cause waste. Because the initial installation and commissioning of the mesh belt conveyor is an important link for good or bad use in the future, the initial installation and commissioning of the mesh belt conveyor is particularly important. The installation and commissioning of the mesh belt conveyor is divided into five steps:
(1) Horizontal installation of mesh belt conveyor: After installing the fuselage, adjust each foot until the whole machine is level.
(2) Installation of the mesh belt: When installing the mesh belt, pay attention to measuring the contact size between the chain and the track, and ensure that the mesh belt and the track are re-divided into contact without distortion or offset.
(3) Adjustment of tension: The initial adjustment of the tension of the mesh belt should be slightly looser than the normal tension.
(4) Drive motor installation: The motor should be fixed firmly, the chain should be tensioned normally, and then the sealing cover should be installed.
(5) Debugging and starting: The starting point of the mesh belt conveyor should adopt the point starting method, adjust the frequency converter to 40HZ, observe no noise and vibration, and then press the button completely.
Initially, the installation and adjustment of the mesh belt conveyor must first adjust the parallelism and horizontality of the mesh belt. If the parallelism is not good, the mesh belt will be unevenly stressed. Use the jog mode when starting, and gradually adjust the speed to the required level after starting, usually it is better to reach 60% of the normal speed within 24 hours. In general, a good mesh belt conveyor must not only be designed but also debugged. Long-term operation can only be guaranteed if the debugging and installation are correct.
