Description

Molding machine for producing food containers using pulp {Pulp Mold Machine}

The present invention relates to a molding for producing a food container that does not cause environmental pollution by using pulp, and more particularly, to a molding machine to obtain a large amount of production with a small production equipment.

Recently, with the rapid development of society, modern people prefer fast and easy things to adapt to the rapidly changing society, and especially foods, they prefer instant foods with short cooking time and easy to eat.

However, in order to transport and sample the above-mentioned instant food, a container for containing food is required, and such a container usually uses a single-use disposable container.

Conventional disposable containers are generally molded using resin or metal foil as raw materials, and these disposable containers do not need to be returned, and most of them are discarded.

However, as described above, the disposable container made of resin or metal causes environmental pollution because almost no decay occurs in the natural state, and in order to regulate this, the disposable container has recently been amended by amending regulations and laws for the disposable container. Although the use of containers is regulated, it is not well observed.

Accordingly, in recent years, the disposable container is manufactured from pulp that is easily closed, and the configuration of an apparatus (hereinafter, a food container manufacturing molding machine) for this will be briefly described below.

The conventional food container manufacturing molding machine is a raw material supply unit for supplying a predetermined amount of the raw material liquid containing pulp, and a room temperature dehydration unit, a heating dehydration unit, and a press molding unit for molding a product using the pulp liquid supplied from the raw material supply unit. It is composed.

In addition, the raw material supply unit constituting the food container manufacturing machine for forming the lower mold and the discharge mold for discharging water, and the same shape as the lower mold carrier net and the carrier net and the raw material for raw material supply It consists of a tank and a discharge pump.

In addition, the room temperature dehydration unit, the heating dehydration unit and the press molding unit is composed of the upper mold provided with a blower tube path and a heat transfer plate for blowing air for dehydration to the lower mold, the carrier net and the lower mold as described above.

And, the food container manufacturing molding machine having the configuration as described above is arranged in duplicate so that the carrier net can be circulated to improve the production efficiency.

Looking at the arrangement structure with reference to Figure 1, first in one row, the product stacking part, the raw material supply unit, room temperature dehydration unit, heating dehydration unit, press molding unit and product stacking part is sequentially arranged, the other side spaced apart from the one side row The papermaking standby part, the raw material supply part, the room temperature dehydration part, the heating dehydration part, the dehydration part, and the product lamination waiting part which hold the carrier net discharged from the final product lamination part of one side row were sequentially arranged along the circulation direction of the carrier net.

According to such a conventional configuration, since the work is done in duplicate at the same time, there is an effect of increasing the output, but since the devices are placed in a double spaced space, the cost and space for production are increased, and the initial installation cost is increased, which puts an economic burden on the producer. .

In addition, there is a problem that requires a lot of manpower and time to maintain and repair because of the use of many equipment.

An object of the present invention for solving the above problems is to provide a dewatering molded part and a product stacking part on both sides of a raw material input part, and the carrier net is reciprocated left / right, while one side supports the molded product on the carrier net. By moving the upper mold with the upper mold supported and the other side with the molding supported on the upper mold and the carrier net in the next process, the number of molds is greatly reduced and the space for the equipment is reduced, resulting in increased product production efficiency. To improve.
