Description

The utility model relates to the field of national economy, namely to the manufacture of devices for hermetically sealing glass jars with metal lids, mainly for home canning.

A device is known for hermetically sealing glass jars with metal lids (Ukrainian patent No. 73261, publ. 09/10/2012), which contains a handle with a central screw on which the pressure disk is rigidly mounted, a base located between the pressure disk and the handle with the possibility of rotational and radial movement, with a seaming roller and a handle mounted on it.

A disadvantage of the known design is:

- reduced operating life of the seaming roller due to wear of its outer surface that interacts directly with the metal cover during the rolling of the glass jar;

- insufficient reliability of the seaming machine.

This design is the closest in functionality and technical result, which is claimed and accepted by us as a prototype.

The utility model is based on the task of improving the seaming machine by changing the design of the seaming roller.

This problem is solved as follows: in a semi-automatic seaming machine containing a handle with a central screw on which the clamping disk is rigidly mounted, a base located between the clamping disk and the handle with the possibility of rotational and radial movement, with a handle mounted on it and a seaming roller made of polymer material, according to a utility model, the roller on the outer surface further comprises a metal crown.

As the polymeric material, for example, host forms C9021, etc. can be used.

The design of the machine, which is claimed, coincides with the prototype for a number of basic design features.

Common signs are:

- a handle with a central screw on which the clamping disk is rigidly mounted;

- a base located between the clamping disk and the handle, with the possibility of rotational and radial movement ,;

- handle;

- seaming roller made of a polymer material.

Distinctive features are:

- a metal crown on the outer surface of the roller.

The technical result, which is claimed:

- improving the reliability of the machine;

- increase its operational resource.

A causal relationship between the existing features of the proposed solution and the obtained technical result provides new technical characteristics that, together with the known features, allow to obtain the technical result indicated in the statement of the problem.

According to the information available to the applicant, the proposed set of features that characterize the essence of the utility model is unknown from the prior art, that is, it meets the criterion of “novelty”.

The utility model is illustrated in the drawing. In Fig 1. presents a General view of the machine in the context.

The semi-automatic seaming machine comprises a handle 1 with a central screw 2, on which a clamping disk 3 is fixed, fixed by a nut 4. The base 5 is movably located between the clamping disk 3 and the handle 1 and contains a cam 6, which interacts with the nut 7. To the base 5 using bolts 8 attached to the handle 9 and the sealing roller 10 with a metal crown 11.

The seaming machine is semi-automatic as follows.

With the left hand, take the machine by the handle 1 and rotate the handle 9 counterclockwise until it stops. After that, the handle 9 is moved from the center and the machine with the clamping disk 3 is mounted on the metal cover and the handle 1 is pressed with the left hand.

Turn the handle 9 clockwise with your right hand. When the base 5 is rotated, the cam 6 rotates the running nut 7, which moves down the screw thread 2 and affects the cam 6, moving it together with the base 5 and the sealing roller 10 to the center of the can. In this case, the roller 10 through the crown 11 affects the rim of the metal cover, gradually deforming it and thereby tightly pressing the rubber ring to the neck of the glass jar.

After 7 revolutions, the movement of the roller 10 is stopped and the rolling process ends.

The proposed utility model can be implemented in an industrial environment, therefore, meets the criterion of "industrial applicability".

Claims (1)

Semi-automatic seaming machine, comprising a handle with a central screw on which the clamping disk is rigidly mounted, a base located between the clamping disk and the handle with the possibility of rotational and radial movement, with a handle mounted on it and a seaming roller made of polymer material, characterized in that the roller on the outer surface further comprises a metal crown.
