Abstract

The utility model provides a roller structure with a belt deviation preventing function, which comprises a rotating shaft and a roller body which are coaxially connected, wherein a circle of limiting groove is formed in the circumferential direction of the roller body, and the limiting groove is used for limiting a conducting bar arranged on the inner side of a belt. The belt guide device has the beneficial effects that the limit groove is formed in the cylinder body in a circle and is matched with the belt provided with the guide strip, so that the belt can be effectively prevented from deviating, the maintenance cost is reduced, and the working efficiency is improved.

Description

Roller structure with belt deviation preventing function

Technical Field

The utility model relates to a roller structure with a belt deviation preventing function.

Background

Before the driving source transmits power to the roller to drive the belt to operate, the belt needs to obtain a certain pretightening force through tensioning, so that the designed transmission power can be achieved when the belt operates. However, the belt is easy to deflect after being tensioned, and in order to solve the problem, the roller is mostly designed into an arc-shaped structure with a concave middle part to limit the deflection of the belt at present, but in actual operation, the limiting effect of the structure is poor.

SUMMERY OF THE UTILITY MODEL

In view of the above defects, the present invention aims to provide a roller structure capable of effectively preventing a belt from deviating, and to reduce maintenance cost.

The utility model provides a roller structure with a belt deviation preventing function, which comprises a rotating shaft and a roller body which are coaxially connected, wherein a circle of limiting groove is formed in the circumferential direction of the roller body, and the limiting groove is used for limiting a conducting bar arranged on the inner side of a belt.

Preferably, the limiting groove is located in the middle of the barrel.

Preferably, the rotating shaft and the cylinder are integrally formed.

Preferably, the rotating shaft is connected with an output shaft of a motor, and the motor drives the rotating shaft to rotate.

The belt guide device has the beneficial effects that the limit groove is formed in the cylinder body in a circle and is matched with the belt provided with the guide strip, so that the belt can be effectively prevented from deviating, the maintenance cost is reduced, and the working efficiency is improved.

Detailed Description

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and are not intended to limit the present invention.

In the description of the present invention, it should be noted that the terms "inside", "outside", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, which are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and operate, and thus, should not be construed as limiting the present invention.

The utility model provides a roller structure with a belt deviation preventing function, which comprises a rotating shaft 1 and a roller body 2 which are coaxially connected, wherein the rotating shaft 1 and the roller body 2 can be connected in a welding mode or integrally formed, and compared with welding, the integrally formed structure can greatly reduce the processing technology and the processing cost. A circle of limiting groove 3 is formed in the circumferential direction of the barrel 2, and the limiting groove 3 is coaxial with the barrel 2 and used for limiting a conducting bar 5 arranged on the inner side of a belt 4. The "inner side" herein refers to a side of the belt 4 contacting the drum 2. In the specific implementation, the limiting groove 3 is located in the middle of the barrel 2, and those skilled in the art can adjust the size of the limiting groove 3 and the position of the limiting groove on the barrel 2 as required. The structure may be applied to a driving roller or a supporting roller which is in contact with the belt 2, and when applied to the driving roller, the rotation shaft 1 is connected to an output shaft of a motor (not shown) which drives the rotation shaft 1 and the drum 2 to rotate.

When the device works, the rotating roller drives the belt 4 with the guide strip 5 arranged on the inner side to run, and in the process, part of the guide strip 5 is embedded in the limiting groove 3 all the time. The limiting groove 3 can help the belt 4 to cling to the barrel 2, so that a good driving effect is guaranteed, the belt 4 can be helped to keep the moving direction in the initial state, and deviation is prevented.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
