Description

Container discharge device for rimming molding machine {DISCHARGE DEVICE FOR RIMMING MOLDING PLASTIC CONTAINER}

The present invention relates to a container dispensing device for a reaming molding machine, and in particular, disposed at an outlet side of a reaming molding machine for reaming and molding the flange portion of a plastic container in a simple manner, and rapidly outwardly stacking plastic containers continuously reaming and molding. It relates to a container discharge device for a reaming molding machine whose structure is improved so that it can be discharged.

In general, various types of plastic packaging containers have been conventionally manufactured by methods such as injection molding.

A conventional container is composed of a container having an open top for putting food therein, and a lid coupled to an upper rim of the container to seal the container.

However, existing plastic containers are classified into those with and without lids, and those without lids are used as packaging containers by placing an object to be packaged, such as food, in the container, and then wrapping the upper rim of the container with a wrap.

Prior art related to existing plastic containers includes Korea Utility Model Registration No. 20-0307755 "Plastic Container Alignment and Fixing Frame" (registration date: 2003.03.05), the upper side of which is formed in a circular cross section A standardized plastic container is formed, a plurality of fixtures formed to be inserted and fixed to the upper side of the plastic container are formed to be interconnected in the X-axis and Y-axis, and supports formed on the outer surface of the fixture are attached to the body frame, respectively. By being formed to be integrally connected, a plurality of fixtures are formed to be interconnected in the X-axis and Y-axis inside the body frame, and the support formed on the fixture is integrally connected to the body frame, and the fixture is formed on the lower side and the upper side The inner plate and the outer plate are interconnected so that a plastic container having a circular cross section can be inserted, and a body frame is provided so that a fixture is inserted into the upper side of the plastic container, respectively, so that each container is fixed to the body frame. , so that a number of plastic containers can be conveniently and stably loaded vertically.

Prior art related to a manufacturing apparatus for manufacturing such a plastic container is Korean Utility Model Registration No. 20-0319476, "Disposable cooking container manufacturing apparatus" (registration date: 2003.06.30), as shown in the frame rotation A lower mold having a container forming groove, a motor for rotating the lower mold, an upper mold installed on the upper part of the lower mold and inserted into the container forming groove, an upper mold holder supporting the upper mold, an elevating cylinder for lifting the upper mold, and one side of the lower mold. It is configured to include a cutting member installed on the molded cooking vessel to uniformly cut the upper rim, and a curling member installed on the other side of the lower mold to form a curl on the flange of the cooking vessel.

By the way, it is preferable that the existing container is molded at an angle where the rim part is inclined toward the outside as it goes upward for demolding with the mold, and the container with this structure is formed in a sharp rim cutting surface, so that the user's hand is in contact with it. In this case, there is a risk that the plastic wrap will be torn or the user's hands will be cut in the process of covering the plastic wrap.

In order to prevent this, a process of curling the flange of the container is required, and the above curling process refers to the process of forming a rim at the end of the trimmed container, which increases the strength of the product and It is a process performed to provide stability to the product by removing the sharp part of the product.

However, as described above, as the container is molded at an inclined angle for demolding with the mold, the general press machine does not transmit uniform pressure during curling, so different pressure is transmitted to each part, resulting in a high defect rate, In particular, in the case of a rectangular container, it was very difficult or impossible to curl the square container due to the imbalance of compression force in a general press machine due to the flange structure of the container.

Another prior art to solve this problem is Korean Patent Registration No. 10-1459748, "Container Discharge Device for Reaming Molding Machine" (registration date: 2014.11.03), which preheats a plastic container using a preheater. Afterwards, the flange portion of the container is removed using a molding machine composed of an upper mold and a lower mold.

However, in the case of the existing reaming molding apparatus, a discharge device for continuously discharging the continuously molded plastic container is required.
