BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a wrapping apparatus for wrapping, which comprises a raw material production unit, a raw material supply unit, and a casting unit.

More particularly, the present invention relates to a unit for producing a raw material in an automated wrapping apparatus for easily producing a wrapping wrap, a unit for supplying a raw material, And to a casting unit.

The wrap film is used for packaging of boxes, bags and commodities. Conventional wrap films made of PVC are suitable resins in terms of price and performance, and are excellent in softness, adhesiveness and transparency, and are excellent in moldability. It is the most widely used material in the world as a material for packaging products.

For wrapping purposes, for example, wrapping or eating food and putting the remaining food into a lid can be done simply by wrapping a single wrap or wrap without worrying about the smell, or wrapping the wrap before putting it in a microwave It is used very conveniently in real life because it prevents evaporation of water to prevent hardening of food.

To manufacture such a wrap film, a wrap manufacturing apparatus has been developed. Most of the conventional lab manufacturing apparatuses are configured in such a manner that a raw material for manufacturing the lap is separately prepared and the prepared raw material is supplied at the first stage of the lap manufacturing process of the lap producing apparatus to produce the lap film. That is, the production process of the raw material for the production of the wrap film is omitted.

Further, in the conventional wrap manufacturing apparatus, in the process of winding the wrap film in the process of manufacturing the wrap film, it is common to wind the wrap film as it is. In this case, the roll of the wrap film wrapped in the roll form is cut There is a problem that it is necessary to separately perform the process of performing the process.

In addition, the conventional wrap manufacturing apparatus has disadvantages in that, in the case of a wrap film produced in a defective state or in the case of a wrap film manufactured to a size not meeting the product standard, it can not be regenerated and is discarded.

In order to solve such a conventional problem, the inventor of the present invention has proposed a method for producing a wrapping wrap by introducing the following constitution to produce a raw material, a film (wrap), a film, The process of cutting the both sides of the roll is automated until the production process of the wrapping wrap becomes quick and the film can be wound into a roll shape by cutting the film to a size that can be provided to the consumer in the process of forming, , A wrapping wrap manufacturing apparatus has been developed which can reproduce a remaining divided film cut to a width that does not meet the specifications of a product in a process of dividing the film into a plurality of pieces and using the same as a raw material.

The present invention relates to a raw material agitator for mixing raw materials for the production of wrapping wrap; A cooling stirrer for cooling while mixing the raw materials mixed in the raw material stirrer; And a raw material crusher for crushing the supplied raw materials into chip form and feeding them in one direction, wherein the mixed and cooled raw materials are supplied to the cooling agitator, and the raw material producing unit is provided.

The packaging wrap manufacturing apparatus comprises: a hopper into which a raw material in the form of a chip transferred from the raw material crusher is charged; A transporting space extending in a direction perpendicular to the longitudinal direction of the hopper; A transfer screw installed in the transfer space in parallel with the longitudinal direction of the transfer space and transferring the chip-shaped raw material supplied into the transfer space in one direction while melting; And a raw material supply unit installed outside the transfer space and connected to the transfer screw and rotating the transfer screw.
