Description

[Detailed description of the invention] (Industrial application field) The present invention has a plate-shaped kneading hand placed facing the curved axis of the kneading bottom board curved in an arc shape, and the kneading hand is placed against the kneading bottom board. The present invention relates to a tea milling machine that massages tea leaves interposed between the two by reciprocating in a curved direction, and particularly relates to the structure of the rolling machine.

(Prior art) As a conventional technology, there is a structure shown in FIG. 3.

That is, an outer panel 3 made of a metal plate is curved into an arc shape, and a large number of elongated main bodies 1 made of hard wood with a trapezoidal cross section are formed on the inner surface of the outer panel 3, with the center of the curved axis of the outer panel 3. Rivets arranged in parallel in parallel 4
There was a structure in which the main bodies 1 were integrally fixed together, and saw-toothed twisted teeth 2 were formed by the inclined upper surface 1a and the thicker upright surface 1b of each main body 1.

(Problems to be solved by the invention) In the above-mentioned conventional device, the main body 1 is fixed to the inner circumferential surface of the outer plate 3 with rivets 4 to form the threaded teeth 2, so the threaded teeth 2 are worn out. Or, if it is damaged, each main body 1 along with the outer panel 3 must be replaced with a new one, which not only increases repair costs, but also
There was a drawback that repair work was time-consuming.

The object of the present invention is to obtain a structure of a rolling machine in a new tea manufacturing and rolling machine that eliminates the above-mentioned drawbacks.

(Means for Solving the Problems) In order to achieve the above object, the present invention is constructed as follows.

That is, a serrated tooth base extending substantially parallel to the curved axis of the main body is formed on the inner surface of the main body curved in an arc shape on the side of the curved axis, and a tooth base made of a thin plate material is formed on the surface of the tooth base. The teeth are removably fixed, and the false teeth surround the surface of the tooth base.

(Function) Since the present invention has the above structure, the false teeth attached to the tooth stand come into direct contact with the tea leaves during rolling.

Also, if you replace the false teeth with new ones,
The kneading performance will return to its initial state.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 1 is a partially sectional side view showing a part of a rolling machine according to an embodiment of the present invention.

Reference numeral 10 denotes a main body which is cast and molded from an aluminum material, and is curved into an arc shape, and has a serrated tooth base 11 formed on the inner surface on the curved axis side.

The tooth stand 11 is formed to extend substantially parallel to the curved axis of the main body 10, and has a cross-sectional shape that is similar to that of the main body 10.
It consists of a steep climbing side 11a that is steeply inclined and extends toward the curved axis of the main body 10, and a gentle climbing side 11b that is gently inclined and extends from the top of the steep climbing side 11a toward the curved direction of the main body 10. Form into a scalene chevron shape.

A large number of false teeth 12 made of a copper plate material are removably fixed to the surface of the tooth base 11 with set screws 13.

As shown in FIG. 3, each false tooth 12 has a scalene valley consisting of a steeply descending side 12a along the steeply ascending side 11a of the tooth base 11 and a gradually descending side 12b along the gradually ascending side 11b of the tooth base 11. By forming the false teeth 12 into a shape and fixing the slowly descending side 12b of the false teeth 12 to the gradually rising side 11b of the tooth base 11 with a set screw 13, the tooth base 11
surrounding the entire surface of.

According to the above embodiment, the tooth stand 11 formed on the inner peripheral surface of the main body 10 is surrounded by each false tooth 12, so that when rolling the tea leaves, the false teeth 12 come into direct contact with the tea leaves. I will do it.

In this case, the false teeth 12 are formed in a valley shape and are attached along the tooth base 11, so that one end edge 12c of the false teeth 12 that abut and overlap each other is at the top 11c of the tooth base 11. It will be located in

Therefore, the apex A1 of the twisting tooth A formed by assembling the false tooth 12 becomes an acute angle due to the edge 12c, and the twisting performance is improved.

Furthermore, when the false tooth 12 is made of a copper material, according to the applicant's test results, it was found that the green color of the tea leaves was not lost and the flavor did not deteriorate.

If the false tooth 12 becomes worn or damaged due to use, the set screw 13 is loosened and the false tooth 12 concerned is replaced with a new false tooth. Thereby, the kneading performance of the false tooth 12 can be maintained at a low cost and for a long period of time.

(Effects of the invention) Since the present invention is constructed as described above, it has the following effects.

(1) The tooth surface formed on the inner surface of the main body is removably surrounded by false teeth, which prevents wear or damage to the tooth base. As a result, the life of the device has been significantly extended.

(2) When the false teeth become worn or damaged, they can be replaced easily and cheaply.

(3) Since the top of the twisting tooth formed by assembling the false tooth has an acute angle due to the edge, the twisting performance is improved.
