Description

Upper mold for making machine of air packing bag and making machine having the upper mold}

The present invention relates to an upper mold for an air packaging bag thermo fusion molding machine and an air packaging bag thermo fusion molding machine having the same, and an upper mold for an air packaging bag thermo fusion molding machine having a thermo fusion pattern forming unit which can be adjusted in more detail and the same. It relates to an air packaging bag heat fusion molding machine having.

Hereinafter, the background art and its problems will be described.

In general, expensive home appliances such as laptops and TVs are generally stored in an outer packaging box and packaged in an outer packaging box to protect them from falling and external shocks that may occur during transportation. to be.

Such an inner packaging container is generally molded using styrofoam so that the outer side is the same as the outer packaging box and the inner side is shaped to be the same or similar to the outer appearance of the packaged product, thereby preventing the product from shaking in the outer packaging box. To prevent damage.

Also, in recent years, in order to protect the environment as an inner packaging container, a paper packaging container that can be easily disassembled is used, or in the case of a small product such as a video or a portable cassette, an air cap is used.

However, since the inner packaging container manufactured using the styrofoam as described above should have an inner shape similar to that of the packaged product, a separate mold must be manufactured for each packaged product, thereby increasing the manufacturing cost. As the volume of the product is too large, it is impossible to bulk load it at the place of packing, so there is a problem in that it is inconvenient to use by bringing a certain amount to the place of packing periodically in a separate storage place, and also for the internal packaging of large products. If the machine had a problem that is very difficult to handle.

In addition, while solving the problems of the inner packaging container manufactured using the styrofoam as described above, the inner packaging container made of paper used in recent years in terms of environmental protection, the production cost is reduced because the mold is not used during the manufacturing Not only can it be saved, but the loading space can be used efficiently, but there is a space between the packaged product and the outer packaging box, causing the product to shake inside the outer packaging box or impact on the packaged product. There was a problem that often occurs.

In the case of the air cap, in the case of a small packaged product, the packaged product can be safely protected from an external impact. However, in the case of a large packaged product, the air storage chamber is closed by the pressure applied by the packaged product. As the popping cases are frequently generated, there is a problem in that they cannot be used as an inner packaging container of a large packaged product.

Therefore, in recent years, in order to solve the problems described above, an air packaging bag in which a plurality of unit air cells in which air is filled is formed by heat-sealing a film laminated in a plurality of layers using a heat fusion molding machine.

However, a mold of a general heat fusion molding machine used in manufacturing the air packaging bag, especially an upper mold, is formed to protrude integrally with a heat fusion pattern forming part on a base to meet the requirements of an orderer who requires unit air cells of various sizes. In order to make a separate upper mold according to the size of the formed unit air cell, each has to produce a separate upper mold, which leads to an increase in the manufacturing cost has a problem that eventually increases the supply cost of the air packaging bag.

In addition, since the upper mold must be replaced according to the size of the unit air cell, not only the production operation of the air packaging bag can be continuously performed, but also the upper mold is heated by the heater in order to restart the thermo fusion molding machine after assembling the upper mold. There is a problem in that the productivity is lowered by preheating it to a predetermined temperature or more.

Accordingly, it is an object of the present invention to provide an upper mold for an air packaging bag heat fusion molding machine and an air packaging bag heat fusion molding machine having the same, which can produce an air packaging bag having unit air cells of various sizes without replacing the upper mold.

The upper mold for an air packaging bag thermo fusion molding machine according to the present invention is a part of the air packaging bag thermo fusion molding machine, the base being detached from the up and down moving plate of the air packaging bag thermo fusion molding machine, and the bottom surface of the base by a gap adjusting means. Detachable and includes at least one thermal fusion pattern forming unit is installed to adjust the spacing.

Air packaging bag heat fusion molding machine according to the present invention, the base detachable to the vertical moving plate; And an upper mold having at least one heat fusion pattern forming part installed on the bottom of the base to be detachable by the gap adjusting means and adjustable in the gap.

According to the present invention, it is possible to provide an upper mold for an air packaging bag heat fusion molding machine having a heat fusion pattern forming unit capable of adjusting an interval, and an air packaging bag heat fusion molding machine having the same.

Therefore, by rearranging only by adjusting the spacing of the heat fusion pattern forming unit can produce an air packaging bag having a unit air cell of various sizes, so that the air packaging bag producer can reduce the burden on the mold production cost and at the same time There is an advantage that can reduce the production cost of the packaging bag.

Also, even if the size of the unit air cell of the air packaging bag to be manufactured is changed, the heat sealing can be performed in response to the changed size of the unit air cell only by adjusting only the interval of the heat fusion pattern forming unit formed within a short time without replacing the previously installed upper mold. In addition, there is an advantage that can improve the production efficiency because there is no need to preheat the upper mold.
