SU438408A1 - DEVICE FOR TRIMING THE END OF FRUITS - Google Patents

Description

one

The invention relates to the canning and vegetable-drying industry, namely, devices for trimming the ends of fruits, such as onions.

A similar device is known comprising a housing with mounted therein with the possibility of simultaneous rotational and reciprocating movement by the sleeve and the cutting mechanism.

The proposed device reduces waste and is more reliable in operation. This is achieved by the fact that inside the sleeve there is a spring-loaded stop, and the cutting mechanism is designed as an annular section of a spherical surface hinged on the sleeve so that the processed end of the fruit freely passes inside the cutting mechanism.

FIG. 1 shows the proposed device, a longitudinal section; in fig. 2 - the same, when pruning the end of the fetus; in fig. 3 and 4 - the cutting mechanism in two positions.

A device for trimming the ends of knots, for example a bow 1, comprises a body 2 with mounted therein with the possibility of simultaneous rotational and reciprocating movement by a sleeve 3 and a cutting mechanism 4 made in the form of an annular portion of a spherical surface fixed with a hinge 5 on the sleeve 3

so that the free end of the bow 1 freely passes inside the cutting mechanism.

Inside the liner 3 there is a spring-loaded spring 6 stop 7, which moves reciprocatingly, interacting with the cutting mechanism by means of the pin 8 and ensuring the latter to rotate in a vertical plane.

The cutting mechanism 4 is mounted on the hinge 5 in the sleeve 9, rigidly connected with the end of the spring 6. The sleeve 3 is equipped with a cone 10, centering the fruit.

The housing 2 is attached to the traverse 11 with the actuator 12.

The device works as follows.

Onion 1 is fed oriented to

the centering cone 10 of the sleeve 3, and

its end enters the cutting cavity

mechanism.

Upon further progress, until contact of the cone 10 with the surface of the fetus, gplz 3 stops. However, the sleeve 13, which receives rotation from the actuator 12, continues to move progressively along the crosshead P. In this spring 6, by means of which the rotation from the actuator 12 is transmitted to the sleeve 9, is compressed, and the pin 8 rotates the cutting mechanism 4, which is set to

the process of rotation under the action of centrifugal forces cutting edge in a horizontal plane around the axis.

Due to the fact that the axes of rotation and rotation of the cutting mechanism 4 intersect, a spherical hole is cut out.

During the return stroke of the crosspiece 11, the pin 8 releases the cutting mechanism 4, and under the action of centrifugal forces it is set by the cutting edge in the horizontal plane, while the trimmed end of the fetus is dropped from the cutting mechanism.

The knife, having the form of an annular spherical surface, has great strength and does not create an imbalance of the rotating masses (rotation speed up to 3000 rpm), which increases the durability of the mechanism.

Subject invention

A device for trimming the ends of fruits, such as an onion, comprising a housing with mounted therein with the possibility of simultaneous rotational and reciprocating movement by a sleeve and a cutting mechanism, characterized in that, in order to reduce the amount of waste and increase

the reliability of the device in operation; a spring-loaded stop is located inside the sleeve, and the cutting mechanism is designed as an annular section of a spherical surface hinged on the sleeve so that the processed end of the fetus passes freely inside the cutting mechanism.
