Working principle of square swing screening machine

　　The screen surface of the square swing screening machine is arranged horizontally or slightly inclined, usually at an angle of 0 to 5 degrees. When the screening machine is started normally, the screen box will move back and forth under the action of inertia force, and drive the screen surface to swing periodically. The material is evenly dispersed on the entire screen surface from the center to the outer edge, making a planar rotary motion. Therefore, materials smaller than the screen aperture are successfully separated and discharged by falling through the screen aperture, while larger particles are continuously rolled and transported to the outlet in a jumping motion. The outlet is an adjustable guide device that can effectively control the flow rate of materials and the residence time of materials on the screen surface, thus completing the screening work. The sentence is:.

Product characteristics of square swing screening machine

1. The equipment adopts a fully enclosed structure, which prevents dust from flying and reduces noise during operation, meeting environmental protection requirements.
2. The vibration motor adopts imported ordinary motors as the transmission source, introduces German technology, and the transmission method imitates manual screening.
3. The square swing screening machine adopts a soft swing form for screening, which can effectively protect the original state of material particles from being damaged, especially suitable for flammable, explosive and static materials, such as raw materials.
4. Combining circular, elliptical, and linear motion modes, the screening effect is good, suitable for screening various materials, with high screening accuracy. It can screen multiple layers and classify impurities to meet different customer requirements.
5. Adopting advanced steel wire rope suspension structure ensures more balanced operation of the equipment.
6. The device is equipped with an automatic tensioning and automatic cleaning screen installation system, which increases the utilization rate of the screen, prolongs its service life, and makes the process of replacing the screen easier and faster.

Composition of square swinging screening structure:
The square swing screening machine is mainly composed of components such as screening box, driving device, screening frame, support frame, and vibration reduction device.
The sieve box includes components such as a sieve frame, sieve mesh, sieve grid, spring card, and bouncing ball. The sieve frame is equipped with upper and lower layers of sieve mesh. The sieve mesh is tensioned on the sieve grid by spring cards set around the periphery of the sieve grid, and the bouncing ball is set in the grid of the sieve grid;
The driving device includes components such as a driver, an electric motor, a locking sleeve, a locking round nut, a stop washer, and a cone sleeve. The cone sleeve is fixed on the screen frame, and the driving shaft of the driver is set inside the cone sleeve and connected and fixed in position through the locking sleeve. Compared with existing screening machines, the fine screening machine of this utility model has the advantages of advanced and practical structure, stable and reliable performance, convenient installation and debugging, and low manufacturing cost.

Square swing screening machineProduct maintenance:
When conducting a weekly inspection of the square swing screening machine, all loose bolts of the equipment should be tightened, especially the bolts of the exciter, screen surface, and support device, which should be paid special attention to. Rough operation is strictly prohibited to prevent damage to the equipment.

2. Carefully check the tension of the triangular belt of the equipment in daily life, and tighten it appropriately if necessary.

3. The screening frame is an important component of the equipment, and it is necessary to pay more attention to the welding seams of the main beam and all crossbeams in daily life to ensure that the welding seams are tight and there will be no cracks.

When maintaining the screen mesh, it is necessary to replace the severely worn screen mesh. Even if it is a new screen mesh, it should be re tensioned every 4-8 hours until it is fully tensioned.
