Description

[Detailed Description of the Invention] The present invention relates to an electric Shirane in which a fixed mortar is provided on the main body of the screw with a built-in screw, and a rotary mortar is provided on the screw for feeding the material, and the rotary mortar is attached using a rotary mortar cover. Then, the rotary mill cover is configured so that the hook part provided on the rotary mill cover is hooked on the white cover hook part of the rotary mill cover of the screw to transmit the information, and between the hook part and the white cover hook part of the rotary mill cover. A relief part is provided at the top of the rotary mill to allow the waste material leaking out from the gap between the screw and the rotary mill.

An embodiment of the present invention will be described below with reference to the accompanying drawings. As shown in the diagram, 1 is a screw.

It is integrated with the screw shaft 2. The screw shaft 2 is rotated by an electric motor (not shown). Reference numeral 3 denotes a screw body with screw 1 built in, which is designed to guide the material. This is an input hole for inputting 4Fi material. 6 is a cover, 2 screws, and a flange part 6 of the main body 3.
The hook portions 9, 1o are adapted to be hooked onto the protrusion portions 7.8. The cover 6 is provided with a cover bearing 11.

The cover 6 is also provided with a screw 12 into which an adjustment screw 13 is screwed. A fixed mortar 14 made of ceramic is attached to the flange portion 6 of the screw main body 3 with some clearance in the axial direction. A buffer plate 16 is inserted between the fixed die 14 and the flange portion 6 to provide cushioning properties.

18 is a material cutting surface of the fixed die 14. A rotary mill 19 made of ceramic is attached to a rotary mill cover 20 via a buffer plate 21 with fixtures 22 such as rivets. 23 is the mounting tool 22
A gap y is provided between the caulked portion and the one-turn mill cover 20. 24 is the material cutting surface of the rotating mill 18, and the fixed mill 1
It faces the material cutting surface 18 of No. 4. Rotating mill cover 20
A hook portion 25 consisting of a plurality of concave and convex portions is formed at the center, and a flat portion 26 is provided at the tip thereof.

The hook portion 26 of the rotary mill cover 20 is adapted to engage with a mortar cover hook portion 27 having an uneven shape formed on the outer periphery of the tip of the screw 1 inserted into the center of the rotary mill cover. A gap is formed between the mortar cover hook part 27 and the flat part 26 of the rotary mortar cover 20, and serves as a release part 28 for material waste. Rotary mill 1 attached to rotary mill cover 20
9 is a fixed mortar 1 via a white presser foot 29 and a presser spring 3o.
It is pressed to the 4th side. Presser spring 5oij: is inserted into the screw shaft 2 at the tip, and is prevented from being removed by a stop shaft 31. A thrust receiver 32 is press-fitted into the tip of the screw shaft 2, and a thrust receiver 33 is also press-fitted into the tip of the adjustment screw 13. The screw shaft 2 has a cover 6
cover bearing 11 and.

The screw is rotatably supported by a bearing portion 34 of the main body 3. Material cutting surface 2 of rotating mill 19 and fixed mill 14
By contacting 4.18.

The material supplied during this time is crushed and comes out from the outlet 35 of the cover 6. Material cutting surface 24.1
8, the screw shaft 2 is pushed in by screwing in the adjusting screw 13, and the contact state between the one-turn mill 19 and the material cutting surface 22, 18 of the fixed mill 14 can be adjusted by the presser spring 30.

Now, the material that has entered through the input hole 4 is sent by the screw 1, guided to the central opening of the fixed mill 14, and entered between the fixed mill 14 and the rotary mill 19, and as the screw 1 rotates, the material is Since the rotary mill 19 rotates, the material is crushed and exits from the external part to the outlet 36.

Here, there is a slight gap between the screw 1 and the rotary mill 19, and even if the material leaks to the outside through this gap, the mortar cover hook 27 and the hook 27 of the rotary mill cover 20
6 and is discharged to the outside through a relief section 28 provided between the two. Therefore, material is prevented from accumulating in the gap B between the hook portion 26 of the rotary mill cover 20 and the end face of the mortar cover hook portion 27 of the screw 1, which is generated when the adjustment screw 13 is tightened.

As described above, since the electric motor of the present invention attaches the rotary mill to the screw through the single-turn mill cover, no stress is applied to the rotary mill, improving durability, and preventing the gap between the screw and the rotary mill from being applied. Even if material waste leaks out, a gap is provided between the hook between the screw and the rotary mill cover to allow the material waste to escape, so material waste will not accumulate between the rotary mill and the screw. This has the excellent effect of ensuring that the rotary mill always moves normally.

Claims (1)

[Claims] A screw rotatably driven by an electric motor, a screw main body containing the screw, a rotary mill attached to the screw via a rotary mill cover, and a fixed mill attached to the screw main body opposite to the rotary mill. and
The rotary mill cover and the screw engage a hooking portion formed at the center of the rotary mill cover, which is made up of a plurality of uneven portions, and an uneven white cover hooking portion formed on the outer periphery of the tip of the screw inserted into the center of the single-turn mill cover. At the same time, a gap is provided between the hook portion and the mortar cover hook portion to serve as a release portion for material waste.
