Technical Field

The invention relates to the grain milling machine used for grinding cereals.

In particular, the invention relates to a grain milling machine that reduces torque motor costs and saves energy due to the fact that the roller motors that perform the grinding process are driven by a belt-pulley system and, at the same time, a torque motor.

Prior Art

Grain milling machines are used for grinding cereals at milling plants. The mentioned grain milling machines basically grind the grains by crushing them through roller balls making rotational movements.

In the prior art, a belt pulley or torque motor is used as the drive system in the rotational movement of the roller balls in grain milling machines. In the drive system carried out with the belt pulley system, a motor for each is used separately from the grain milling machine, and there are a total of four roller balls, two pairs at the front and back of the machine. Each motor rotates by driving a pair of roller balls. The said motor is connected to the pulley in the grain milling machine with the help of a belt using a pulley. In this way, with the help of the two roller balls in the front and another belt and pulley positioned at the back of the machine, the two roller balls at the back are moved. Since the motors are independent of the grain grinding machine in the said belt and pulley system, assembly labor is required, and a constant need for spare parts arises depending on the working principle realized with the belt pulley. At the same time, due to the movement transfer provided by the belt pulley, power losses are experienced, and energy consumption increases. In addition, these motors meet the required rotational force (torque) by consuming more energy. In addition, an extra level is required at the bottom of the machine for the connection of the motors.

In the drive system realized with a torque motor for the movement of the roller balls in the grain milling machines, the roller balls are rotated directly from both sides by the torque motor. Therefore, the product cost increases in the drive system that is connected only to the torque motor. This led to the need for a grain milling machine working with a drive system with reduced torque motor costs in the prior art.

In the literature survey, the document numbered WO2017089870 was found as an example of the current art. The said document concerns a new rolling mill with direct drive motors for grinding and processing cereals, granular materials, cereal mixtures and similar products. Each cylinder of each pair of parallel cylinders on the said machine is equipped with a drive motor. And this leads to an increase in costs.

As a result, the existence of the above problems and the inadequacy of existing solutions necessitated an improvement in the relevant technical field.

The Purpose of Invention

The invention relates to a grain milling machine to eliminate the disadvantages mentioned above and bring new advantages to the relevant technical field.

The primary purpose of the invention is to introduce a grain milling machine that enables the roller motors that perform the grinding process to be driven by a belt-pulley system together with a torque motor.

The purpose of the invention is to reduce the cost of torque motors by using a torque motor that works in conjunction with a belt pulley system.

Another purpose of the invention is to save energy by performing the rotation force with less power by preventing the belt pulley system that rotates the roller motors from being driven by an external electric motor.

Another purpose of the invention is to facilitate the assembly of the grain milling machine.

In order to fulfill all the purposes mentioned above that may arise from the detailed description, the invention is a grain milling machine used in grinding grains, consisting of a frame and a double cylinder roller mill that crushes grain and coarse-grained materials by rotating movement on the front and back of the frame,

- comprising a large poly V pulley connected to the front roller ball, a small poly V pulley attached to the roller ball on the back, and a belt pulley system with a timing belt that is associated with the large poly V pulley and the small poly V pulley, allowing the rotational movement of the roller ball in the front to be transferred to the roller ball located on the rear side, - and a torque motor that is associated with at least one roller ball and allows the roller balls to rotate.

The structural and characteristic features and all advantages of the invention outlined in the drawings below and in the detailed description made by referring these figures will be understood clearly. Therefore, the evaluation should be made considering these figures and detailed explanations.

Detailed Description of the Invention

In this detailed description, preferred embodiments of the grain milling machine of the invention will be explained only for a better understanding of the subject matter and without any restrictive effect.

In Figure 1 , the view of the grain milling machine of the invention is given. Accordingly, the grain milling machine in its most basic form consists of a frame (10), a pair of roller balls (20) that grind grain and coarse-grained materials by making a rotational movement on the front and rear of the frame (10), a belt pulley system (30), which is associated with the roller balls (20) and ensures the rotation of the roller balls (20) in the opposite direction to each other, and a torque motor (40) that provides the rotational movement of the roller balls (20). The roller ball (20) that forms the main structure of the grain milling machine of the invention is in the form of a cylinder and is double-bedded side by side on the front and back sides of the frame (10). The roller ball (20), which makes a rotational movement on the front side, needs a tensioning so that it can rotate the roller ball (20) located on the back side in the opposite direction. For this, a large poly V pulley (31) is connected to the roller ball (20) at the front, and a small poly V pulley (32) is connected to the roller ball (20) at the rear, and by means of the timing belt (33) associated with the large poly V pulley (31) and the small poly V pulley (32), the rotational movement of the roller ball (20) in the front is transferred to the roller ball (20) located at the rear. Thus, it is ensured that each pair of roller balls (20) make a rotational movement in the opposite direction to each other. At least one tensioning delrin (34) was connected to the timing belt (33), and the tensioning of the timing belt (33) was ensured.

The rotational movement of the roller balls (20) is driven by a torque motor (40) connected to at least one roller ball (20).

The working principle of the grain milling machine of the invention is as follows;

By energizing the torque motors (40), the torque motors (40) drive the large poly V pulley (31) in the belt pulley system (30). By means of the timing belt (33) associated with the large poly V pulley (31) and the small poly V pulley (32), the rotational movement of the roller ball (20) at the front is transferred to the roller ball (20) at the back. In this way, with the rotation movement of each pair of rollers (20) in opposite directions to each other, grain and coarse-grained materials are crushed and ground.
