SU472687A1 - Herb Cutting Machine - Google Patents

Description

one

The invention is intended for cutting herbaceous and leafy raw materials, such as dill, parsley leaves and celery, tobacco, and is used in the canning industry.

Machines for cutting herbal raw materials are known, comprising a housing, a cutting drum, whose blade cylindrical surface is reinforced with blade knives, located with a slight slope to the cylinder, feeding device and a spring-loaded deck.

However, such maschins do not provide particles of certain sizes and shapes.

In order to improve the cutting accuracy in the proposed machine, the spring-loaded deck is made in the form of a set of alternating knives of different thickness, while the cutting edges of some knives are arranged in the longitudinal plane, and the cutting edges of others are in the transverse plane, the cutting drum is assembled from cutters alternating with gaskets serving for interacting with deck knives with longitudinal cutting edges.

In addition, in the spring-loaded deck over each horizontal cutting edge there are windows whose dimensions do not exceed the specified sizes of the cut particles.

In order to dose the material into the working space, the feeding device is made in the form of a rubberized roller that interacts with the teeth of the cutting drum, and the roller speed is less than the circumferential speed of the drum.

FIG. 1 schematically depicts the described maschina in the interaction of the mills with a thick fire; in fig. 2 - the same, in the interaction of mills with a thin nol-som; in fig. 3 is a section along A-A in FIG. 2; pas figs. 4 is a section according to BB and FIG. 2

The machine consists of a cutting drum, assembled on the drive shaft 1 of disc

cutters 2 alternating with spacers 3 having a diameter equal to the diameter of the circle of the cutters; spring-loaded sickle deck 4, also recruited from knives 5, having a thickness equal to the thickness of the cutters, the cutting edges of which are located in the transverse plane alternating with the knives 6, having a thickness equal to the thickness of the spacers 3, and located in the longitudinal plane.

The knives 5 have windows 7, the outer edges of which 8 form a cutting pair with the tip of the tooth of the 9 mills. Knives (3 on the concave part have a sharpened blade inserted into the gap between the fre3

clamp, and rest on the spacers 3, pressing the spring 10 against them.

The product is supplied by a set of cutters 2 and a rubberized roller 11 having a linear rotation speed less than the rotation speed of the cutters.

The drum, rollers and deck are housed in a housing 12 having openings for loading and unloading the product.

Maschina works as follows.

The product feed is carried out by milling cutters 2 and a rubberized roller 11 rotating at a speed lower than the speed of rotation of the mills, whereby the relative movement of the mills and the material, the preliminary introduction of the tool tips to the material and the dosing of the feed occur. The gap between the rubber-roller and the mills can be adjusted.

The material captured by the cutters is drawn into the narrowing gap between deck 4 and the drum, and when the tips of the cutters interact with the outer edges 8 of the entrenchment 7, the product is cut across the flow of the strip with a length equal to the length of the drum 2. The strips with a width equal to the step of the cutter teeth are pulled through the knives 6 and are cut into segments equal to the thickness of the mills, and then thrown out for unloading.

Product particles that are smaller than the window 7 in the knives 5 of the crescent deck 4 and not caught by the teeth of the milling cutters are thrown out through the window 7 and are also delivered for unloading.

Thus, the particles of the cut material are limited in magnitude by the accepted

four

Hiaroii and thick cutters and can not be more than these sizes.

By changing the step size and thickness of the cutters, it is possible to obtain particles of a rectangular or square shape of the required size.
