Carbon Steel 63.5mm Spiral Return Roller With Deep Groove Ball Bearing

Spiral Screw Conveyor Roller For Industry Machinery Belt Conveyor​

The Screw roller is mainly used to clean up the debris adhering to the tape, and can play a role in adjusting the deviation. The structure is as follows: Weld left and right spiral round steel with a diameter of 10 to 14 mm on the ordinary roller or add a spiral groove cast rubber sleeve on the outer surface to increase the entire roller, which can clean the adhesive on the tape, and it can be belt type. The service life of the conveyor belt, but also plays a role in adjusting the center to prevent deviation.

The principle of the Screwroller to prevent deviation is: the two side rollers in the roller group are Screw rollers with a taper, but the spiral direction of the thread is different, one roller is left-handed, and the other roller is right-handed Rotate so that the lateral force given to the conveyor belt is directed to the line. When the conveyor belt is running, due to the action of the spiral, axial forces are generated respectively. When running off, the conveyor belt slides to one side and receives the thrust of the helix angle to the belt. The greater the outer side, at this time, the two rollers produce different forces to push the conveyor belt. The difference between the two forces will be Prompt the conveyor belt to reset. When the spiral roller is installed on the conveyor belt, the spiral of the middle roller should be bidirectional, that is, one end is a left spiral, and the other end is a right spiral. One side of the rollers on both sides is left-handed thread, and the other side is right-handed thread. The key to installing the screw roller is that it can face the tail of the conveyor, and then install the right-hand threaded roller on the right hand side and the left-hand threaded roller on the left hand side.

Requirements for the use of Spiral Return Roller:

1. According to the belt width or machine opening width, select the rollers and brackets that match the specifications;

2. Install the supporting roller bracket on the side beam of the conveyor correspondingly. (Symmetry deviation is not more than 2mm)

3. Enlarge the shaft shells of the two ends of the supporting roller into the ear groove of the bracket, and the horizontal angle between the supporting roller and the frame is 20 or the distance of the corresponding bracket. (The angle and distance of the oval hole at the bottom of the bracket can be adjusted)

4. When the rollers are running, the spiral direction must be consistent.

5. The installation distance of each group of rollers can be designed according to the specific gravity of the conveyed materials, and the general installation distance is 0.8-1.0m.

6. The bearing part is equipped with grease nipple, and the oil is injected every 6 months.

7. The impact force during conveying operation shall not exceed 300Kg/m.

8. This product can be used in the range of -40?-70?, and if the range is exceeded, it should be proposed in advance. Special specifications of spiral rollers can be designed and produced according to the user's different climatic conditions, working media and models.

9. During transportation and storage, it is forbidden to prevent heavy pressure, mechanical damage and grease nipple damage.
