Description

The invention relates to the field of commercial engineering and can be used for the packaging of agricultural products (potatoes, onions, etc.) before their implementation in commercial enterprises operating according to the method of self-service.

Devices for sealing packages with metal straps are known, consisting of a housing, an actuator, a metal tape feeding mechanism, a knife for cutting the embedded package, a die and a punch.

Closest to the invention is a device in which a bracket of metal tape is formed by bending an array of metal in the shape of

open ring. The metal tape is fed by the tape feeding mechanism into the slit ring, and with further feeding it slides along the inner surface of the ring, taking the shape of a circle. After the tape feed is finished, the punch cuts it and enters the ring out, squeezing the tape there, and then returns to its original position.

The disadvantage of the device is that the finished bracket is removed from the die only along the longitudinal axis of the inner surface of the ring. When a groove is made during operation at the point where the metal strip slides along the inner surface of the ring, the recess of the ready-made bracket from the die becomes impossible. 00

Oh comes mz st. To restore it, it is necessary to replace the matrix

The chain of the invention is increased reliability in operation.

To achieve the goal of a bag sealing device, having a body, a drive, a punch, a metal tape feed mechanism, a knife for cutting a sealed bag, the matrix is made of two parts, one of which is rigidly fixed on the body, and has the ability to move the first one and contains lever with hinge. A double-arm lever is hinged on the casing; the punch is additionally equipped with an L-shaped pull with a stop, which is installed with the possibility of interfacing with one of the two shoulders of the double shoulder. the other arm of which is pivotally connected with the lever of the movable part of the matrix, 1 shows a device for sealing packages, a general view; FIGS. 2-4, brackets forming circuits,

The device for sealing packages includes a housing 1, an actuator 2, a fixed part 3 of the matrix, rigidly fixed. On the case 1, a movable part 4 of the matrix, having a lever with a hinge, and able to move relative to the fixed part 3 matron, punch 5, feed mechanism 5 metal tape, knife 7 for cutting off the package. Drive 2 is a motor with a gearbox. A lane 8 is attached to the core 5, and a stop 9 is installed on it. On housing 1, there is a double-arm lever 10, one end of which interacts with the stop 9, and the second pivotally connected to the lever of the movable part 4 of the matrix. Also installed on the housing 1 mechanism b feed tape and

G OIZOD 2,

The device works as follows after the filing of the wire harness 11 in not

the movable part 3 of the matrix is included

drive 2 and punch 5 coupled to

oh, it starts moving. When moving

punch 5 moves connected to it

L-shaped ha 8 and the stop 9 mounted on it, runs over the shoulder of the two shoulders lever 10, turns it, while the second shoulder acts on the movable part 4 of the matrix, moving it to the grid harness. The feed mechanism 6 from the metal tape starts the feed, and the tape 12, slipping along the fixed part 3 of the matrix and the moving part 4 of the matrix, forms a circle, bending around the wire rope 11.

Punch 5 with further movement cuts the tape 12 and compresses it in the matrix, giving the bracket the shape shown in Fig.Z. At the same time, the knife 7 cuts the wire bundle between the brackets. The punch 5 starts to move in the opposite direction and exits the die. The L-shaped bar with its protrusion moves the double-arm lever 10, which shifts the movable part 4 of the matrix from the stationary part 3, freeing the zone for the exit of the bracket in the direction A (figure 4). The punch 5 returns to its original position, the actuator 2 is turned on.

Thus, removing the finished bracket

It is carried out with the shifted movable part of the matrix not only along the longitudinal axis of the matrix, perpendicular to the axis, which significantly increases the service life of the device and reliability of operation.
