Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a grinder for grinding coffee beans, spices, etc. The main bearing rubber of the main shaft to which the cutter is attached is compressed to reduce vibration noise, etc. This is what I did.

An embodiment of the present invention will be described below with reference to the accompanying drawings.
In the figure, 1 is the main body of the cooking machine, juicer mixer, mixer, etc., 2 is the electric motor built into the main body 1, 3 is the lower connector attached to the tip of the main shaft of the electric motor 2, and 4 is the main body 1
The body of the crusher placed on top has a recess 4a in the center.
Each has an annular convex portion 4b on its outer periphery. Reference numeral 5 denotes a container for storing the pulverized material, and the center of the bottom surface is formed to protrude upward, and is formed into an arc shape with the base as the apex.

14 is a lid that fits into the upper end of the container 5, and 6 is a main bearing fixed to the lower center of the container 5, into which an oilless bearing 7 is press-fitted.

8 is a main bearing rubber inserted into the outer periphery of the main bearing 6, and 9 is a completed container product consisting of an assembly of the container 5, the main bearing J6, and the main bearing rubber 8. 8
It is inserted into the body 4 so that it fits in, and is fixed with a rivet 10 at a seat 4e provided on a part of the convex portion 4b.

At this time, the convex portion 4b and the lowest surface of the bottom of the container are in contact with i,
The bottom of the container changes from the broken line state in FIGS. 2 and 3 to the solid line state, compressing the main bearing rubber 8 in the direction of the arrow in FIG. 3. Reference numeral 11 denotes a main shaft, which is inserted into an oilless bearing 7 and has a cutter 12 rotatably driven in the container 5 at its tip.
An upper connector 13 that fits into the lower connector 3 is attached to the lower end.

15 is a cushioning rubber provided at the lower end of the body 4.

When the body 4 is attached to the main body 1 in the above configuration, the lower connector 3 and the upper connector 13 are fitted together q, and the electric motor 2
The rotation of the coffee beans is transmitted to the spindle IL cutter 12.
It is used to crush spices, etc.

Here, the upper surface of the main bearing rubber 8 located in the recess 4a of the body 4 is connected to the lower surface of the container 5 (or the tube 6a of the main bearing 6),
The lower surface is provided so as to be in contact with the bottom surface 4C of the body 4.

As a result, the main bearing rubber 8 expands in the side direction of the recess 4a of the body 4, thereby reliably holding the main bearing 6, and transmitting rotational noise, vibration noise, etc. caused by the rotation of the cutter 12 to the recess side surface 4.
It is buffered and absorbed between the main bearing rubber 8 and the lower surface of the container 5, the bottom surface 4C, and the main bearing rubber 8. Note that the number of contact areas between the container 5 and the body 4 is reduced by the convex portion 4b, so that the transmission of vibration to the body 4 is reduced. As described above, in the present invention, the main bearing rubber is provided between the main bearing and the body that constitute the rotating part, and this main bearing rubber is compressed in the vertical and horizontal directions and is densely provided. The body is securely held, and the rotational noise and vibration noise caused by the rotation of the cutter are not transmitted to the body, so it can be used without any abnormal noise, which leads to improved quality and product image.

Although the description has been given of a case in which the body and the main body are separable, the present invention is not limited to this, and the same applies even if the body and the main body are integrated.
