Selection and installation of sliding switch of belt conveyor Installation method and matters needing attention Selection and installation of sliding switch of belt conveyor Installation method and matters needing attention
Jan .31.2023
Selection and installation of sliding switch of belt conveyor Installation method and matters needing attention:
The relation between the diameter of the conveying drum of the belt conveyor and the belt layer of the conveyor belt, the matching of the driving drum, the groove Angle of the reversing drum and the drum should be selected reasonably according to the design regulations of the conveyor.
The feed direction shall be in the running direction of the conveyor belt. In order to reduce the impact of falling materials on the conveyor belt, chute should be used to reduce the falling distance of materials.
The receiving part of the conveyor belt should shorten the spacing between idler wheels and use buffer rolls as leakage materials.
The belt conforms to a soft and moderate baffle to prevent the baffle from being too hard and scratching the belt surface of the conveyor belt.

Selection principles and precautions:
Select the appropriate installation method according to the product type; Non-contact sliding switches should be installed away from strong electromagnetic interference and covered with a metal cover.
The slip alarm value should be set after the actual measurement; The speed parameters of each belt conveyor are usually different, and the actual belt running speed is also affected by the installation method and structure of the conveyor, so each conveyor must be set up one by one. The action alarm value of the sliding switch of the machine.
Some products can automatically avoid low speed when the conveyor starts: the conveyor will power the slide switch at the same time the conveyor starts. After the slide switch is energized, after a period of time, it will begin to detect belt speed normally. Try to display real speed and remote display. A product that transmits speed signals.
By installing two protective devices, steer switch and slide switch, belt conveyors can effectively reduce the possibility of conveyor failure, reduce downtime, and better protect transportation equipment and personnel. The products corresponding to the measuring range should be selected according to the actual moving speed of the belt conveyor being measured; Usually, when the conveyor is in normal operation, the speed of the belt running line is about 2.5-4m /s, and the speed of the drum is about 50-300rpm. At the same time, in addition to comparing the rotation speed of the drum and the speed of the conveyor belt, and comparing the sliding switch type, choose the product that can automatically avoid the low speed when the conveyor belt starts. Because the slip alarm of the coal conveyor belt is actually a low speed alarm, therefore, the slip alarm should be shielded during the start of the conveyor. A delay detection method for belt startup can be used (i.e., the delay is delayed for some time after the start of startup, and the working power of the skid switch is turned on after the belt conveyor reaches the belt. Normal speed), but more cumbersome to implement.
What are the factors affecting the service life of the steel wire rope conveyor belt What are the factors affecting the service life of the steel wire rope conveyor belt

2, according to the terrain of the conveying line and the relationship between the adjacent equipment. Determine whether the conveyor conveyor line is set up curve section, or whether the intermediate need to set transfer point.
3, according to the nature of conveying materials and working environment, can determine the speed, bandwidth.
4, according to the production requirements of the conveyor, can determine the specifications of the conveyor.
The above is the large dip Angle belt conveyor selection requirements and basis, hope to help you.
What are the reasons for the cracking of rubber conveyor belt joint What are the reasons for the cracking of rubber conveyor belt joint
Jan .31.2023
There are usually three kinds of rubber conveyor belt joint. The rubber conveyor belt is a mechanical joint, a cold rubber joint and a hot vulcanized joint. The strength of conveyor belt joint is lower than the strength of its own belt body. When the conveyor belt uses mechanical joint, the joint strength can only reach 40-50% of the strength of the belt body. When cold adhesive is selected for the conveyor belt, the joint strength can reach 60-70%. When hot vulcanized joints, the joint strength of the conveyor belt can reach 80-90%.
The strength of the conveyor belt joint is relatively low. If the bonding method is not accurate, the strength of the conveyor belt joint will be lower. If the cutter and conveyor belt grinding damage the next layer of canvas, grinding too much, the lap length is not good, the number of steps is not good, the rubber function of the joint is not good or has already self-sulfur failure, steel wire rope grinding too much, steel wire rope rust, etc., the strength of the joint will be greatly reduced, when in use, it is easy to show the scene of conveyor belt joint disconnection and cracking. If the conveyor belt does not choose sealing glue, or the direction of the joint is wrong, the joint (surface glue part) will also show the cracking scene.
Avoid cracking from the source, add cracking inspection equipment, check the results in the shortest time, send an alarm and stop. Belt tear is formed by a variety of factors, can not completely avoid the cracking of the conveyor belt, tear prevention equipment and inspection equipment is mainly torn inspection equipment, usually located in the blanking point, composed of sensors and controllers, sensors installed under the conveyor belt or chute, controller installed in the machine side or indoor.
