Description

Technical Field

[0001] The utility model relates to the technical field of toothed V-belt production, in particular to a grinding machine for producing rubber toothed V-belts. Background Art

[0002] Belt transmission is one of the important transmission forms of mechanical transmission. With the continuous improvement of industrial technology and the requirements for precision, lightweight, functional and personalized mechanical equipment, there are more and more transmission forms and their application scope is getting wider and wider. The conveyor belt transmits the power generated by the rotation of the prime mover's motor or engine to the mechanical equipment through the pulley, so it is also called a power belt or conveyor belt.

[0003] The existing Chinese utility model patent with reference announcement number: CN214519401U discloses a grinding machine for rubber V-belt production, including: a first conveying roller, on which the rubber V-belt is sleeved; a left grinding mechanism, which is arranged on one side of the rubber V-belt on the first conveying roller, and includes a left grinding disc, the plane where the left grinding disc is located forms an acute angle with the length direction of the rubber V-belt, and the left grinding mechanism is arranged on a first front-to-back moving mechanism, which is used to adjust the distance between the left grinding disc and the rubber V-belt, and the first front-to-back moving mechanism is arranged on a first left-to-right moving mechanism, which is used to adjust the position of the left grinding disc in the left-to-right direction. The rubber V-belt production grinding machine shown in the utility model has a simple structure, can automatically grind the rubber V-belt, and has the advantages of being easy to use and can be easily adjusted.

[0004] Existing grinding machines generally use a motor to drive the roller to rotate the V-belt to change the relative position between the cutting tool and the V-belt. In this way, the relative position between the V-belt and the tool cannot be fixed during the cutting process, which causes errors in the spacing between the V-belt tooth structures. Since the rubber material has a certain deformation ability, when the tool contacts the V-belt during the grinding process, the V-belt will be compressed and deformed, affecting the tooth shape.
