Screw Conveyor Belt Tensioning Devices

The spiral tensioning device of the belt conveyor includes a slide frame and a screw rod. The slide frame is fixed with a nut connected to the screw rod with a thread width. It also includes a fixed bracket. Both ends of the screw rod are rotationally connected to the fixed bracket. The fixed bracket is provided with The guide rail is parallel to the screw, and the slide frame has a slide groove that matches the guide rail. This device is installed on the conveyor through a fixed bracket. It is easy to install and easily meets the requirements of product series. The guide rails on the fixed bracket play a supporting role in the slide frame and can improve its strength. The two ends of the screw are supported on the fixed bracket and will not Deformation.

It is generally adjusted manually through a screw or through a small hydraulic cylinder to lock and fix the device after reaching the required tightening force. The spiral tensioning device is generally placed on the tail frame of the belt conveyor, and the tail roller serves as the tensioning roller. When the machine head roller is used as a tensioning roller, the spiral tensioning device is placed on the machine head frame.

The characteristics of spiral tightening are simple structure and compact arrangement. However, the tension and stroke of manual adjustment of spiral tensioning are small, and the adjustment of the tensioning force is based on experience and observation of the status of the conveyor belt. The pretension force cannot be kept constant automatically and needs to be adjusted frequently. Belt conveyors generally used on small belt conveyors and equipment.

Specifications

Performance features:

Flexible and adjustable: The screw can flexibly adjust and control the tension of the nut and object by adjusting the rotation speed and direction of the driving device.

Tight connection: Due to the role of threads, screws and nuts can achieve a relatively strong connection, thereby ensuring the stability of the connected objects.

High bearing capacity: Due to the mechanical characteristics of the thread, the screw and nut can withstand large pulling forces and are suitable for occasions requiring higher tension.

Application: Steel, metallurgy, coal, cement, power generation, ports and other industries.

Conveyor Belt Tensioning Devices Industry knowledge

What is the load-bearing capacity of screw conveyor belt tensioning devices? What tension requirements are suitable?
1. Definition of load-bearing capacity
The load-bearing capacity refers to the pull or tension limit that the screw conveyor belt tensioning device can withstand under normal working conditions. This ability affects the tension adjustment of the conveyor belt, ensuring that the conveyor belt maintains proper tension during operation to prevent slipping, loosening or damage.

2. Design and materials
Material: Screw conveyor belt tensioning devices are usually made of high-strength steel or alloy materials, which have good tensile strength and wear resistance to withstand large tensile forces.
Structural design: The design parameters of the screw, such as the diameter, pitch, and thread depth, will directly affect the load-bearing capacity. A well-designed screw tensioning device can effectively disperse the load and reduce local stress concentration.

3. Load-bearing capacity range
Standard load-bearing capacity: Generally speaking, the load-bearing capacity of screw conveyor belt tensioning devices can reach thousands to tens of thousands of Newtons (N), and the specific value depends on the specifications and design of the device.
Suitable tension requirements: Screw tensioning devices commonly used for small and medium-sized belt conveyors are generally suitable for load-bearing tensions ranging from 500 to 5000 Newtons; for large conveying systems, devices with stronger load-bearing capacity, reaching tens of thousands of Newtons, may be required.

4. Impact of the use environment
High temperature and humidity: In high temperature or humid environments, the load-bearing capacity may be affected, especially material fatigue and corrosion. Therefore, it is particularly important to choose a screw tensioning device made of high temperature resistant and corrosion-resistant materials.
Load changes: During operation, the load-bearing capacity of Screw Conveyor Belt Tensioning Devices also needs to take into account factors such as the type of material, the width and length of the conveyor belt, and the operating speed.

5. Regular maintenance and inspection
In order to ensure that the Screw Conveyor Belt Tensioning Devices always work within their load-bearing capacity, it is recommended to perform regular inspections and maintenance. This includes:
Checking thread wear
Ensuring that the screw device is well lubricated
Monitoring tension changes and adjusting them in time
