(54) Title: VEGETABLE LEAF CUTTING    MACHINE

(57) Abstract: Vegetable leaves hasher device for cutting Vegetable leaves and cabbage. It
including round blade with circumference edge sharp that is perpendicular it keep rotating continuous while return mover of the Vegetable leaves carry constrain Vegetable leaves to be cut by help of table support, and table support is supported by faller gauge all this, is driven by electricity automatically to produce sliced result of leaves and edible.
 
Vegetable leaf cutting machine  
1 Abstract

The device is for cutting vegetable leaves and consist of six principle parts. The first part is a cutting blade sharpened on its curved surface and rotates about the central axis. The second part is a restricting device that is a vertical plate for setting sizes of cut leaves. A third part is a cutting board supported by the restricting device and is used for adjusting the loading section upon wear of the blade. A fourth part consist of a leaf hopper for holding leaves as they are loaded towards the cutting blade. The leaves are then fed towards the blade by means of a loader, the fifth part, operated by extension springs. The final part is a supporting device for both the loader and hopper. All these parts are made of stainless steel to avoid human contamination.

2   Background

The present invention is a an automated vegetable leaves cutting device. The idea was born out of study of the manual labor involved in cutting of leaves. The manual method is unsafe causing injuries to the hands and is tiresome especially when large amount of vegetable leaves are to be cut. In the development of the invention no similar device was referred to. The device can be used in large scale operations in hotels and other institutions where cut leaves are required for cooking. A prototype has already been constructed and is going through necessary improvements.

3   Outline of    vegetable cutter elements

The following is an outline of the figures making up various parts of the vegetable

cutting    machine.

1.    Figure 1 consists of three major views that is the plan, elevation and an isometric view of the vegetable leaf    cutter

2.    Figure 2 is an isometric view of the cutting blade which is a circular disc whose curved surface has been sharpened to a knife edge.

3.    Figure 3 is the crank mechanism that brings about the reciprocating motion of the leaf feeding    device.

4.    Figure 4 is the leaf hopper having three open sides (to allow movement of loader and the top section    for feeding of    leaves).

5.   Figure 5 is the supporting section fur leaf loader consisting of five bearings.

6.    Figure 6 is a leaf loader that is spring loaded and has bearings at the rear end to ease location on the    supporting device figure 5.

7.   Figure 7 is the cut leaf restricting plate that is rectangular in shape.
3.  One side of shaft 30 is supported by side plate 2 and the other end is supported by the intermediate plate 4.
 On the opposite end of shaft 30 is the crank 31, having a bearing 32 on its free end as shown in figure 3. This bearing runs about a slotted link 33, which is part of the reciprocating motion leaf feeding section. The leaf feeding section consists of three set of parts. One of them is the leaf hopper 34 shown in figure 4 in which vegetable leaves are placed. The second part is the loader support 35, shown in figure 5, for supporting the hopper. The final part is the leaf loader 36 shown in figure 6. for feeding the leaves towards the cutting blade. Feeding of the leaves towards .the cutting blade is achieved by means of extension springs 37 and 38 located underneath the loader.

       At the leaf cutting section are two parts 38 and 39. Part 38 shown in figure 7 is a plate for setting the size of the cut leaves while 39 acts as the cutting board. The cutting board has two slots 40 and 41 as shown in figure 8 and is held on part 38 by means by means of bolts to ease adjustment as    the cutting blade wears.

    The invention described herein with reference to the drawings may be modified without departing from     the scope of the invention.

5   Claim

The following is the list of the main parts being claimed in this invention.

1.    Vegetable leaves cutting blade of claim 1 comprising of a circular blade sharpened to a knife edge on its curved surface. It rotates on its central axis and hangs perpendicular to the table and the leaf loader. This blade made of stainless steel is shown on sheet 2 of 8.

2.   The leaf hopper device claim 3 that is a box open at the top for insertion of vegetable leaves as shown in sheet 4 of    8.

3.   The loader support device claim 2 consisting of a reciprocating section that
moves the leaf loader and hopper back and forth along the table. It consists of a set of bearings and locaters to ensure perpendicular motion with respect to the cutting blade as shown in sheet 5 of 8.

4.    The leaf loader device claim 4 comprising of a feeding plate fitting onto the hooper for forcing the leaves towards the blade. This facilitated by means of extension springs supported on one end as shown in sheet 6 of 8.

5.    The cut leaves sizing device of claim 5 that is a rectangular plate made of stainless steel located on the table. It assists in setting the size of the leaves to be cut and is shown in sheet 7 of 8.

6.    The leaves cutting board device claim 6 for ensuring vegetable leaves do not bend during cutting. This is shown in sheet 8 of 8.
