[0001] The utility model relates to the technical field of grinding mills, in particular to a driving component of a grinding mill. Background Art

[0002] In the existing grinding mill technology field, there are various driving methods, among which belt drive is a more common one. The traditional belt drive grinding mill transmits the power of the motor to the grinding roller through the belt to realize the material grinding operation. However, this traditional belt drive method has some significant disadvantages:

[0003] Difficulty in adjusting the tension: Traditional belt drive systems lack an effective tension adjustment mechanism, which causes the belt to become loose after long-term use, thereby affecting transmission efficiency, increasing energy consumption, and even causing belt breakage and other faults.

[0004] Poor stability: Belt drive is easily affected by external factors such as ambient temperature and humidity, which leads to decreased transmission stability and affects the overall performance of the grinding mill. Utility Model Content

[0005] The purpose of the utility model is to provide a grinding mill drive assembly to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a grinding mill drive assembly, comprising a bracket, a grinding mill body and a tensioning adjustment mechanism, the grinding mill body is fixedly installed on the top of the bracket, a motor is arranged on one side of the bottom of the bracket, a transmission belt is arranged on the output end of the motor, a first transmission wheel is arranged on one end of the transmission belt, a second transmission wheel is installed on the top of the first transmission wheel through transmission belt transmission, two tensioning adjustment mechanisms are installed on one side of the bracket, a screw rod is arranged inside the tensioning adjustment mechanism, a turntable is installed on one end of the screw rod, a threaded sleeve is slidably arranged inside the tensioning adjustment mechanism, a rotating wheel is installed on the front side of the threaded sleeve through a bearing, the rotating wheel abuts against the inner side of the transmission belt, and the screw rod passes through the threaded sleeve.

[0007] The grinding mill body is the main body of the grinding mill, which can grind materials. The transmission belt is driven by a motor, and the transmission belt drives the first transmission wheel and the second transmission wheel to operate, thereby driving the grinding mill body to operate. The device is provided with a tensioning adjustment mechanism on the inner side of the transmission belt. The tensioning adjustment mechanism can rotate the screw rod by rotating the turntable, and then the threaded sleeve moves back and forth inside the tensioning adjustment mechanism, which can drive the wheel to move along the inner side of the transmission belt, thereby changing the tension of the transmission belt. This design makes the tensioning adjustment of the transmission belt simple and quick, reduces maintenance costs and downtime, improves the stability and reliability of the equipment, and reduces transmission failures caused by slackness of the transmission belt after long-term use.

[0008] Preferably, a feed hopper is provided on one side of the top of the grinding mill body, and casters are installed on the bottom of the bracket.

[0009] The staff can put the materials into the grinding mill body through the feed hopper so that the grinding mill body can grind and crush the materials. The casters can facilitate the staff to move the device to the designated position.

[0010] Preferably, the second transmission wheel is arranged on one side of the grinding mill body, and the first transmission wheel is arranged on one side of the bracket through a bearing.

[0011] Because the second transmission wheel is arranged on one side of the grinding mill body, when the second transmission wheel is driven to rotate, it can provide power for the operation of the grinding mill body. The second transmission wheel is arranged on one side of the bracket and can be used as a relay transmission for the second transmission wheel, thereby changing the gear ratio of the motor output end and providing greater torque for the operation of the grinding mill body.

[0012] Preferably, a handle is installed on one side of the turntable.

[0013] The handle can provide a gripping position for the staff's hands, making it convenient for the staff to easily rotate the turntable.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] The device is provided with a tensioning adjustment mechanism on the inner side of the transmission belt. The tensioning adjustment mechanism can rotate the screw rod by rotating the turntable, thereby causing the threaded sleeve to move back and forth inside the tensioning adjustment mechanism, and can drive the turntable to move along the inner side of the transmission belt, thereby changing the tension of the transmission belt. This design makes the tensioning adjustment of the transmission belt simple and quick, reduces maintenance costs and downtime, improves the stability and reliability of the equipment, and reduces transmission failures caused by loosening of the transmission belt after long-term use.

However, after understanding the disclosure of the present application, various changes, modifications and equivalents of the methods, devices and / or systems described herein will be apparent. For example, the order of operations described herein is merely an example, and is not limited to the order set forth herein, but in addition to the operations that must occur in a particular order, changes that will be apparent after understanding the disclosure of the present application may be made. In addition, in order to improve clarity and brevity, descriptions of features known in the art may be omitted.

[0021] The features described herein may be implemented in different forms and should not be interpreted as being limited to the examples described herein. Rather, the examples described herein have been provided only to illustrate some of the many possible ways of implementing the methods, devices and / or systems described herein that will be apparent after understanding the disclosure of the present application.

[0022] Throughout the specification, when an element (such as a layer, a region, or a substrate) is described as being “on”, “connected to”, “bound to”, “over”, or “covering” another element, it may be directly “on”, “connected to”, “bound to”, “over”, or “covering” another element, or one or more other elements may be present between them. In contrast, when an element is described as being “directly on”, “directly connected to”, “directly bound to”, “directly over”, or “directly covering” another element, there may be no other elements present between them.

[0023] As used herein, the term "and / or" includes any one of the associated listed items and any combination of any two or more items.

[0024] Although terms such as "first," "second," and "third" may be used herein to describe various members, components, regions, layers, or portions, these members, components, regions, layers, or portions are not limited by these terms.
