BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plastic can manufacturing apparatus, and more particularly, to a plastic container manufacturing apparatus for manufacturing a plastic container without a neck by cutting a blown intermediate in two steps.

As is well known, the plastic container is not only easy to manufacture, but also has increased use in various fields due to its light and excellent strength, which is not easily broken.

The plastic container is generally divided into a plastic container with a neck and a plastic container without a neck as in a general PET bottle.

In the case of the plastic container with the neck portion, after injection molding the preform (A) for manufacturing a plastic container with the neck portion as shown in Figure 6a, the blowing processing portion (A2) of the preform (A) is put into the mold Then, a blowing process of injecting high-pressure air through the neck A1 while applying heat is performed to complete the plastic container with a neck (see intermediate B shown in FIG. 6B).

On the other hand, in the case of the plastic container (C ') without the neck portion, after injection molding the preform (A') for producing a plastic container without the neck portion as shown in Figure 7a, the blowing treatment portion of the preform (A) (A2 ') is injected into the mold and subjected to a blowing process of injecting high-pressure air through the lid connection portion (A1') while applying heat, thereby removing the plastic container (C ') having no neck portion as shown in FIG. 7B. To complete).

In the case of the plastic container with the neck part, the neck part A1 on which the thread is formed has sufficient thickness and rigidity, so that even if the neck part A1 of the preform A is not blown after injection molding, The external force applied during the process or during the transportation and use of the finished product does not cause problems such as neck deformation or damage easily.

However, in the case of the plastic container (C ') having the neck portion, the lid connecting portions (A1', C1 ') have a thin thickness and rigidity, and are injection-molded during manufacturing or transportation and use of the finished product. When an external force is applied to the lid connecting portions A1 'and C1', problems such as the lid connecting portions A1 'and C1' are easily deformed or broken are caused.

For reference, only the injection-molded portion, such as the lid connecting portion (A1 ', C1') is easily deformed or broken by external force because the particles are not dense and firm, while the blown portion such as the container body (C2 ') is The particles are densely and firmly placed so that they are not easily deformed or broken by external forces.

Therefore, the present invention was invented to solve the above problems, by cutting the blown intermediate over two times, to manufacture a plastic container that can produce a plastic container without the neck portion excellent in the strength of the lid connection portion The object is to provide a device.

The present invention for achieving the above object, Intermediate input unit for injecting the blown intermediate in sequence to the first cutting unit; A first cutting unit which firstly cuts a part of the container body of the intermediate material introduced from the intermediate material feeding unit to remove the neck portion, and then supplies it to the first transfer unit; A first transfer unit interlocked with the first cutting unit to transfer the intermediate material from which the neck portion supplied from the first cutting unit is cut off to the second cutting unit; The second cutting unit is interlocked with the first transfer unit, and secondly cuts the intermediate material from which the neck portion transferred from the first transfer unit is cut off to complete the plastic container without the neck portion, and then supplies it to the second transfer unit. unit ; A second transfer unit interlocked with the second cutting unit to transfer the plastic container having no neck portion supplied from the second cutting unit to the plastic container discharge unit; A plastic container discharging unit for discharging the plastic container having no neck portion transferred by the second transfer unit to the outside; And a drive unit for forcibly driving the second cutting unit.
