Description

Devices for making sausage casings made of cellophane are known, consisting of a reel for cellophane, guide rollers, an applicator, a knife mechanism and a forming head.

The described device differs from the known ones in that, in order to manufacture the shell in two layers, its forming head is made in the form of a vertically mounted and performing intermittently rotational disk, on the end surface of which on a common circle - mounted hollow perforated cylindrical mandrels, rotating around their axes and internally connected with a vacuum line.

FIG. Figures 1 and 2 show the device in two projections.

It is equipped with two powering devices located on both sides of the device and allowing the manufacture of two shells simultaneously. Each such feeding device consists of a roll / cellophane, guide rollers 2 and 3, a pair of guide planes 4, a knife mechanism 5 and an applicator 6.

Between both gluing machines, a forming head is mounted, including a vertically mounted disk 7, performing an intermittent-rotary movement using a ratchet mechanism 8. Hollow cylindrical mandrels I with slit-like slots 10 are attached to the end face of the disk 7 line 11, rotate around their axes.

Above the mandrels is mounted a device for removing the finished shells from them, which is a chain conveyor} 2 carrying the clamps 13 for the shells; the latter interact with pro. filing guide 14.

The knife mechanism 5 consists of a fixed and movable spring-loaded knife, driven by a cam / 5, and a gluing machine is made in the form of a bath for gelatin and a roller-ku. laca 16.

The device works as follows.

The cellophane in the form of a tape unwound from a reel I is supported by guide rollers. and 3 between the rails 4 to the forming head. The end of the tape is sucked to the slit-shaped slot / A-Connected vacuum line. At this point, the cam / 5 drives the movable knife, which, together with the fixed knife, cuts off the tape. The length of the segment is equal to two circumference of the mandrel 9 with the allowance for the seam. The width of the tape and the cut is equal to the length of the shell. At the same time, the first application of a layer of gelatin is made on the edge of a piece of tape using a roller 16. After the mandrel 9 has made one full turn and wound one layer of cellophane over itself, the cellophane gelled again, and the second turn the cellophane is wound on a mandrel and glued. The disc 7 is then rotated by an angle equal to the double angle between adjacent mandrels 9; when approaching the mandrels with shells to the clamps 13, the latter clamp the shells, and the chain conveyor 12 pulls them off the mandrels. The shells released from the clamps fall onto the external conveyor 17 and are removed by it from the device.

Subject invention

A device for making sausage casings of cellophane, consisting of a reel for cellophane, guide rollers, an applicator, a knife mechanism and a forming head, characterized in that, in order to manufacture the casing in two Layers, its forming head is made in the form of a vertical mounted and performing intermittent-rotational movement of the disk, on the end surface of which on a common circle are mounted hollow perforated cylindrical mandrels, rotating around their axes and connected by an inner rim Lost to a vacuum line.
