Description
Technical Field
The utility model relates to a belt elasticity mechanism.
Background
In glass machinery, belt transmission is generally adopted, particularly a bilateral edge grinding machine is adopted, when glass with different thicknesses is ground, the height of a workbench needs to be adjusted, the height of the workbench needs to be adjusted at this time, and the tightness of a belt needs to be adjusted, but the conventional belt tightening mechanism generally adopts a manual screw rod to be connected with a tightening wheel or adopts an air cylinder to be directly connected with the tightening wheel, so that the manual adjustment is troublesome in operation and time and labor are wasted; the cylinder is connected with the elastic wheel, and the elastic wheel and the cylinder are continuously impacted in the long-time running of the belt, so that the cylinder is easy to damage and produces after sales.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a belt elasticity mechanism aims at providing a belt elasticity mechanism that degree of automation is high, receive belt power to strike for a short time.
The utility model provides a belt tightening mechanism, which comprises a belt transmission mechanism with a belt and a belt tightening mechanism, the belt tightening mechanism is provided with a tightening wheel, a cylinder and a swing rod, the tightening wheel is close to the belt or the tightening wheel is contacted with the belt, the elastic wheel is arranged on a swing rod, one end of the swing rod is coupled with the air cylinder, the other end of the swing rod is coupled with the frame or the belt transmission mechanism, the air cylinder drives the swing rod and the elastic wheel to swing so as to loosen or tighten the belt, the swing rod is driven by the cylinder to drive the elastic wheel to swing so as to realize the tightness of the belt, the relative elastic wheel is directly connected with the cylinder to realize the tightness of the belt, this structure becomes the driving force of cylinder elasticity wheel wobbling circumference power, when the belt motion, has reduced the reaction force of the belt that the cylinder received, has prolonged the life-span of cylinder, reduces after sale, improves the stability of elasticity wheel.
In one or more embodiments, the belt transmission mechanism includes a driving wheel and a driven wheel, the belt is disposed between the driving wheel and the driven wheel, and the belt take-up mechanism is disposed near the driven wheel.
In one or more embodiments, the elastic wheel is attached to the inner side of the belt, and the swing rod is coupled with a machine plate of the belt transmission mechanism.
The utility model has the advantages that: the belt is driven to swing through the cylinder driving swing rod to achieve tightness of the belt, the relative tightness wheel is directly connected to the cylinder to achieve the tightness of the belt, the driving force of the cylinder is changed into circumferential force of the tightness wheel in a swinging mode through the structure, when the belt moves, the reaction force of the belt received by the cylinder is reduced, the service life of the cylinder is prolonged, after sale is reduced, and the stability of the tightness wheel is improved.

Fig. 2 is another schematic structural view of the belt tensioner.
Detailed Description
The application scheme is further described below with reference to the accompanying drawings:
referring to the attached drawings 1-2, a belt tightening mechanism comprises a belt transmission mechanism 1 with a belt 3 and a belt tightening mechanism 2, wherein the belt tightening mechanism 2 is provided with a tightening wheel 21, a cylinder 22 and a swing rod 23, the tightening wheel 21 is close to the belt 3 or the tightening wheel 21 is in contact with the belt 3, the tightening wheel 21 is installed on the swing rod 23, one end of the swing rod 23 is coupled with the cylinder 22, the other end of the swing rod is coupled with a frame or the belt transmission mechanism 1, the cylinder 22 drives the swing rod 23 and the tightening wheel 21 to swing so as to loosen or tighten the belt, the swing rod 23 is driven by the cylinder 22 to drive the tightening wheel 21 to swing so as to realize the tightness of the belt, the structure realizes the tightness of the belt by directly connecting the tightening wheel to the cylinder, the structure changes the driving force of the cylinder 22 into the circumferential force of the swing of the tightening wheel 21, and reduces the reaction force of the belt 3 received by the cylinder 22 when the, the service life of the cylinder 22 is prolonged, after sale is reduced, and the stability of the tension wheel 21 is improved.
Further, the belt transmission mechanism 1 comprises a driving wheel 11 and a driven wheel 12, the belt 3 is arranged between the driving wheel 11 and the driven wheel 12, and the belt tightening mechanism 2 is arranged close to the driven wheel 12.
Further, the elastic wheel 21 is attached to the inner side of the belt 3, and the swing rod 23 is coupled with a machine plate of the belt transmission mechanism 1.
The above preferred embodiments should be considered as examples of the embodiments of the present application, and technical deductions, substitutions, improvements and the like similar to, similar to or based on the embodiments of the present application should be considered as the protection scope of the present patent.
