Abstract

A DEVICE FOR CUTTING FOOD PRODUCT, mainly a confectionary layer, containing a frame with a flat knife fixed on it, and a vibrator, characterized in that, in order to increase the reliability of the device and improve the quality of the cut, by providing frame vibration in two directions relative to the movement of the knife and cutting the material, the frame is equipped with spring-loaded horizontal rods mounted in holders mounted on vertical spring-loaded rods with the possibility of reciprocating variable tim vertically.

Description

The invention relates to a device for cutting food materials located on a conveyor belt, and can be used to cut mainly confectionery layers and bundles.

Known devices for cutting food materials containing a frame with a flat knife fixed to it, mounted with the possibility of reciprocating motion relative to the cut product [1] and [2].

The disadvantage of these devices is the low quality of the cut, due to crushing of the material in the cutting zone, the appearance of chips, chipping.

Closest to the proposed technical essence and the achieved result is a device for cutting a food product containing a frame with a flat knife and a vibrator fixed to it. At the same time, drums with circular and flat knives, a drive are located on the frame. The drive motor is connected to the drums through a gearbox by chain gears. In this case, the frame receives non-directional oscillatory motion [3].

In the known device does not provide reliable and durable operation of the mechanisms, since the vibration extends to the chain transmission and drive of the device. The resulting low-quality cut can be explained by the non-directional vibration of the knife and the fact that vibration is transmitted to the knife through the drum. A large mass of oscillating parts leads to the spread of vibration in the area of work of the staff.

The purpose of the invention is to increase the reliability of the device, improving the quality of the cut by providing vibration of the frame in two directions relative to the movement of the knife when cutting the material.

This goal is achieved by the fact that in the device for cutting a food product containing a frame with a flat knife fixed to it and a vibrator, the frame is equipped with spring-loaded horizontal rods mounted in holders mounted on vertically spring-loaded rods with the possibility of reciprocating movement vertically.

A rigid connection of the vibrator and the knife with the frame allows the vibration to be communicated only to the knife, and the energy consumption for creating vibration in this case is minimal. Installing the frame using spring-loaded rods in the holders allows for directional vibration in the horizontal plane, and the nozzle of the holders on the rods and springing them allows for directed vibration in the vertical plane. Two-way vibration communication to the knife improves cut quality.

The drawing shows a diagram of the proposed device.

A device for cutting food materials contains a frame 1 with a flat knife 2 rigidly fixed on it and a vibrator 3 mounted above the conveyor 4, which serves to move the product. Frame 1 with a flat knife 2 and a vibrator 3 is connected to the holders 5 by means of rods 6. The holders 5 are mounted on the rods 7. At the ends of the rods 6 and rods 7 compression springs 8 and 9 are installed. For fixing the springs 8 and 9, nuts 10 and 11 are provided.

The device operates as follows.

The product is continuously fed onto the conveyor belt of the conveyor 4 and cut with a knife 2, which is driven by reciprocating cam-eccentric mechanisms (not shown) connected to the rods 7. The springs 8 return the knife frame 1 to its original position and serve as vibration dampers in the vertical direction. The vibration is created by an unbalanced mechanical vibrator 3. The horizontal vibration is damped by the springs 9, the stiffness of which is regulated by the nut 10. The holders 5 have holes for connecting with the rods 6 of the frame 1, which allow the rods 6 to move in a horizontal direction and prevent them from rotating around its axis. The descent height of the knife frame 1 is regulated by nuts 11.

Using the proposed invention in comparison with the basic device, which is a device for cutting candy, harnesses, created at the Rot-Front confectionery and operating in the production line of unglazed praline varieties of sweets, can reduce metal consumption by 35% (from 400 to 250 ), energy consumption - = by 14% (from 1.8 to 1.55 kW), to improve the presentation of finished products by improving the quality of the cut.

Using the invention in comparison with the prototype, will increase the reliability and durability of the mechanisms in 1.5-2 times.

The economic effect of using one device in the production line of unglazed praline varieties of sweets with a productivity of 1750 tons per year will be 20 thousand rubles. in year.
