Description

Air pumping type rice cake molding extruder {Extruder for molding paste bait}

The present invention relates to a rice cake forming extruder for extruding rice cake material to form rice cake, and more particularly, to an air pumping type rice cake forming extruder in which a user easily presses and supplies with hand or foot to extrude rice cake.

Fishing refers to the act of catching a target fish when the target fish bites the bait by inserting a bait into the hook while the hook is connected to the end of the fishing line. Several types of fishing baits are used, and one of them is rice cakes.

Rice cakes are used as fishing baits by making small, tightly lumped rice cake ingredients that have been given viscosity by pouring water into grain flour. In the fishing process, the operation of forming rice cakes into small sizes is mainly performed by hands, but there was a problem that the hands were dirty and the hands were sore due to the operation of forming rice cakes by the hands.

Therefore, anglers wash their hands frequently, especially in late autumn, as the water temperature gets colder, so washing hands is somewhat painful. Also, people who dislike this process or find it cumbersome, especially women, avoid fishing.

In order to solve this problem, rice cake forming machines have been proposed in Public Utility Model Publication No. 94-23864, Registered Utility Model No. 20-0471584, Registered Utility Model No. 20-0186731, and Patent Publication No. 10-2007-0096152, etc. It was not easy to produce a large amount of rice cakes.

In order to solve this problem, Patent Registration No. 10-1988935 can accommodate a large amount of rice cake material, so there is no need to store the rice cake material in a bowl, so it is possible to prevent the rice cake from being dried by sunlight and wind, and even with a small force. We proposed a rice cake extruder that allows the rice cake to be extruded so that it can be conveniently molded.

However, this rice cake extruder was very cumbersome and difficult to use because the user had to rotate the circular rotating body by hand. Also, the power transmission structure for the rotation of the circular rotating body to be transmitted to the piston is very complicated and the number of components is very complicated. It was difficult to manufacture and broke down very easily, resulting in a short lifespan and poor usability.

In addition, since such a conventional rice cake extruder cannot mold several types of rice cakes at once, but can extrude only a single rice cake, it was necessary to possess several rice cake extruders to form various types of rice cakes, and accordingly, each rice cake There was an inconvenience in that the user had to troubleshoot each extruder.

Public Utility Model No. 94-23864 Registered Utility Model No. 20-0471584 Registered Utility Model No. 20-0186731 Patent Publication No. 10-2007-0096152 Registered Patent No. 10-1988935
