Description

[Detailed description of the invention] This invention allows the spatula in the tea processing machine to elastically slide into contact with the curved inner bottom surface 1 of the container 2 in a constant elastic state without bouncing up the curved inner bottom surface 1 of the container 2. It relates to a spatula operating mechanism in a tea processing machine whose purpose is to smoothly and effectively roughen the tea confections placed in the bottom 1, and a rotating shaft 3 runs vertically through the center of the interior of a container box 2 having a curved inner bottom 1. A bending part 7 of a bending hand rotating arm lever 6 is pivotally attached to the tip of a support lever 5, which is constructed by a rotary shaft 3 and has a base 4 attached to its rotating shaft 3.

2 is attached, and the upper bent arm rod 13 of the bent arm lever 6 is installed along the top surface 14 of the tip of the support lever 5, and the tip of the upper bent arm rod 13 is The upper end edge 17 of a support rod 16 provided vertically through the support rod 5 is pivoted to the edge 15 by a pivot 18, and the support rod 16 is attached to the inner surface 2 of a stop plate 19 attached to its tip.
0 and the lower surface 21 of the support lever 5. The shaft 23 is installed protruding from the upper surface of the base 4 of the lever 5, and the rotating shaft 3 is installed by inserting it into the hole 24', and tightening is done using the nut 2.
5, the support lever 5 is attached to the rotating shaft 3.

In the drawings, 26 and 27 are bolts and nuts used to attach the head 12 of the spatula body 11, 28 is a tea leaf, and 29 is a rough surface for rubbing.

Conventionally, the spatula in this type of roughing machine has its head attached to the lower edge of a rotating arm of the kneading hand, whose base is directly attached to a rotating shaft that extends vertically through the center of the inside of a box having a curved inner bottom surface. A leaf spring is connected to the head of the spatula body to cause the spatula to operate elastically.

In this conventional structure, during the rough rolling operation of tea manufacturing, the spatula body may suddenly bounce up against the repelling force of the leaf spring, which may impede the rough rolling operation.

In contrast, this invention eliminates the drawbacks of this conventional structure and allows the tea confectionery placed in the bottom of the container to slide elastically into contact with the confectionery in an unchanging state without being bounced up. According to this invention, the curved inner bottom surface 1
A rotary shaft 3 is vertically installed in the center of the interior of the container box 2, and a bent portion 7 of a bent kneading arm rotary arm 6 is attached to the tip of a support lever 5 having a base 4 attached to the rotary shaft 3. A head 12 of a spatula main body 11, which is a suitably curved band-shaped steel plate, is attached to the lower end edge 10 of the lower bent arm rod 9 of the bent kneading hand rotating arm rod 6. The upper bending arm rod 13 of the bending hand rotating arm rod 6 is installed along the top surface 14 of the tip of the support lever 5, and the tip edge 15 of the upper bending arm rod 13 is connected to the support lever. The upper end edge 17 of a support rod 16 provided vertically through the support rod 16 is pivoted by a pivot 18, and the support rod 16 is attached to the stop plate 1 attached to its tip.
The spatula main body is elastically supported by a coil spring 22 that is elastically interposed between the inner surface 20 of the support lever 9 and the lower surface 21 of the support lever 5. Since the bent kneading hand is attached to the dynamically supported rotating arm rod 6, the spatula body does not jump up suddenly during the rough kneading operation, and it always slides into soft and constant elastic contact with the tea cake. Therefore, the roughening action is carried out smoothly and effectively, which is extremely useful.
