Description

Technical Field

[0001] The utility model relates to the field of conveying rollers, in particular to a conveying roller table. Background Art

[0002] Rollers are often used to convey longer materials. Conveying rollers include the following two conveying modes: one is that the roller plays an active conveying role. The roller rotates under the drive of the power mechanism and drives the material on the roller forward through static friction. However, when other conveying devices (such as the next station) are needed to act on the material, the roller cannot rotate freely and cannot convert friction into rolling friction. The friction force on the material on the roller is very large, which affects the conveying efficiency and increases the conveying load. The second is that the roller is freely rotated and set on the bracket. The material is conveyed by other conveying devices, and the roller reduces the friction of the material. In this case, the roller only plays a supporting role and has a single function. It is necessary to set up an additional conveying device, which increases the cost.

[0003] For example, the Chinese patent with the publication number CN215709133U proposes a conveyor roller, which places multiple materials such as square steel on the roller. At this time, the lifting cylinder is in a retracted state, and the height of the conveyor roller is below the roller. After the placement is completed, when the roller is used to convey the material, the lifting cylinder drives the conveyor roller to rise, so that its supporting surface is higher than the supporting surface of the roller. At this time, the bottom of the material leaves the roller and only contacts the conveyor roller. The motor drives the active roller to rotate, thereby driving all the conveyor rollers to rotate, and the conveyor roller uses static friction to drive the material to move; when the material moves forward to the end surface leveling mechanism under the action of the conveyor roller, the rotating cylinder piston extends, the rotating cylinder cylinder body rises, and drives the end of the rotating frame cross plate to rise. The rotating frame rotates around the base, thereby driving the leveling surface to rotate to the front of the material head. During the forward movement of the material, it abuts against the leveling surface perpendicular to the conveying direction, and the material head is leveled. The rotating cylinder contracts, driving the leveling surface to rotate in the opposite direction and lift up to make way, so that the material continues to move forward through the end surface leveling mechanism. When the front end of the material leaves the roller and enters the next station, the conveying device of the next station, such as a clamp, clamps the material. At this time, the lifting cylinder drives the conveying roller to descend, so that its supporting surface is lower than the supporting surface of the roller. At this time, the bottom of the material only contacts the roller. At this time, the clamp drives the material to move forward. Since the roller can rotate freely, the roller converts the sliding friction of the material into rolling friction, reducing the friction of the material. However, in this solution, when the motor stops during the conveying process, the conveying roller may not stop rotating immediately due to inertia, resulting in accidents. The safety and reliability are poor. For this reason, we propose a conveying roller. Utility Model Content
