A dental model grinder according to an embodiment of the present invention will be described with reference to fig. 1 to 4.

As shown in fig. 1 to 3, a dental cast grinder according to an embodiment of the present invention includes: a shell 100, wherein the shell 100 is provided with a working window 110; a grinding wheel 200, the grinding wheel 200 being rotatably disposed in the housing 100; the driving wheel 300 is rotatably arranged in the shell 100, the driving wheel 300 is positioned below the grinding wheel piece 200, and the driving wheel 300 is tangent to the grinding wheel piece 200; and the motor 400, the motor 400 is arranged in the shell 100, the motor 400 is in transmission connection with the driving wheel 300, the motor 400 drives the driving wheel 300 to rotate, and the driving wheel 300 rotates to drive the grinding wheel piece 200 to rotate.

For example, as shown in fig. 1 to 3, the grinding wheel 200 has an axis parallel to the front-rear direction, the working window 110 is provided at the front end of the housing 100, and the operator inserts the plaster cast from the working window 110 to grind the plaster cast by the rotating grinding wheel 200. The movement of the grinding wheel 200 in the front-rear direction and the left-right direction is restricted by the housing 100, and the movement in the up-down direction is not restricted, so that the grinding wheel 200 can be conveniently taken out of the housing 100 by moving the grinding wheel 200 upward, the driving wheel 300 is positioned below the grinding wheel 200, the grinding wheel 200 is contacted and tangent with the driving wheel 300 under the action of gravity, and the surfaces of the grinding wheel 200 and the driving wheel 300 are rough, so that the driving wheel 300 can drive the grinding wheel 200 to rotate when the driving wheel 300 is driven to rotate by the motor 400. Therefore, the dental model grinder can conveniently detach the grinding wheel 200 while realizing the function of grinding the dental model, so as to clean or replace the grinding wheel 200.

In some embodiments of the present invention, the present invention further comprises a drawing cover 120, the drawing cover 120 is slidably disposed on the casing 100, two sliding grooves 121 are disposed on the drawing cover 120, a grinding wheel spindle 210 is disposed on the grinding wheel 200, and two ends of the grinding wheel spindle 210 are slidably disposed in the two sliding grooves 121, respectively.

For example, as shown in fig. 2 and 4, the drawing cover 120 is disposed at the upper end of the housing 100, two sliding grooves 121 are disposed in the vertical direction on one side of the drawing cover 120 facing the inside of the housing 100, and two ends of the grinding wheel spindle 210 on the grinding wheel 200 are respectively disposed in the two sliding grooves 121, so that the two sliding grooves 121 limit the movement of the grinding wheel 200 in the front-rear direction, and ensure that the grinding wheel 200 does not deviate in the front-rear direction when rotating along with the driving wheel 300; the grinding wheel 200 can move up and down along the slide groove 121, so that when an operator pulls the pull cover 120 upwards, the pull cover 120 firstly slides upwards relative to the grinding wheel 200 until the lower end of the slide groove 121 contacts with the grinding wheel spindle 210, the pull cover 120 drives the grinding wheel 200 to move upwards together, the pull cover 120 continues to be pulled upwards, and the grinding wheel 200 is pulled out of the shell 100; when the worker inserts the cap 120 with the grinding wheel 200 into the housing 100, the grinding wheel 200 first moves downward along with the cap 120 until the grinding wheel 200 contacts the capstan 300, at which time the cap 120 continues to move downward, but the grinding wheel 200 does not move downward any more due to the support of the capstan 300. Therefore, the grinding wheel 200 can be conveniently taken out of the shell 100 by pulling out the drawing cover 120, and the disassembly of the grinding wheel 200 is further facilitated.

In some embodiments of the present invention, the diameter of the grinding wheel spindle 210 is equal to the groove width of the slide groove 121. For example, as shown in fig. 4, since the diameter of the grinding wheel spindle 210 is equal to the groove width of the slide groove 121, the slide groove 121 further restricts the movement of the grinding wheel 200 in the left-right direction, so that the grinding wheel 200 does not shift left and right when rotating along with the driver 300, and the stability of the dental model grinder is further improved.

In some embodiments of the present invention, a handle 122 is further disposed on the lid 120. For example, as shown in fig. 4, the handle 122 is provided to facilitate the operator to grasp and lift the pull cap 120, which improves the convenience of the present dental cast grinding machine.

In some embodiments of the utility model, the housing 100 comprises: a main case 130; a side housing 140, the side housing 140 being disposed at the right side of the main housing 130, the work window 110 being disposed at the front end of the side housing 140; and a front cover 150, the front cover 150 being disposed at a front end of the main casing 130, the front cover 150 being coupled with the main casing 130 by bolts 151. For example, as shown in fig. 1, an operator may repair the driving wheel 300 and the motor 400 by removing the side case 140, and clean the inside of the housing 100 by removing the front cover 150. Since grinding the plaster cast generates a large amount of plaster dust, the provision of the front cover 150 and the side case 140 facilitates timely cleaning and maintenance of the inside of the case 100 by an operator.

In some embodiments of the present invention, a side of the front cover 150 facing the grinding wheel 200 is provided with a brush, which is in contact with the grinding wheel 200. The side of the grinding wheel 200 facing the front cover 150 is a working surface of the grinding wheel 200 for grinding gypsum, so that gypsum dust is easily remained on the surface, a brush is arranged on the side of the front cover 150 facing the grinding wheel 200 and is in contact with the grinding wheel 200, and when the grinding wheel 200 rotates, the brush cleans the working surface of the grinding wheel 200, so that the durability of the grinding wheel 200 is improved.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
