A fully automatic vertical up and down sealing and cutting shrink packaging machine is a fully automatic shrink packaging machine with a high degree of automation, which can automatically complete the steps of feeding, film wrapping, sealing and cutting, shrinking, etc. Heat shrinkable packaging effect without wrinkle, no need for personnel operation, high work efficiency. The packaged items can achieve the effect of sealing, moisture-proof, and pollution-proof, and protect the items from external impact.
The fully automatic and unmanned "L" vertical upper and lower sealing and cutting machine is widely used in the flow process of mass production and packaging. It has high work efficiency. The automatic film feeding and punching device, the manually adjusted film guiding system, and the manually adjusted feeding and conveying platform are suitable for products of different widths and heights. We have also designed special sealing functions for small packaging products.
The automatic vertical packing machine is suitable for large batch shrink packaging in software, food, cosmetics, printing, pharmaceutical, flooring, ceramics, beverages, hardware, and other industries
A vertical sealing machine is a type of packaging equipment designed to seal and close bags or pouches in a vertical position. The working principle of a vertical sealing machine involves a series of steps to ensure an efficient and airtight seal. Here's a general overview of the working principle:
Bag Feeding: The packaging material, usually in the form of a roll or pre-made bags, is fed into the machine. The bags are positioned in a vertical manner to facilitate the sealing process.
Product Filling: If the machine is part of a packaging line, the product is typically introduced into the bag either manually or through an automated filling system.
Bag Gripping and Transport: The machine uses a mechanism to grip the upper part of the bag securely. The bag is then transported vertically to the sealing station.
Sealing Station: At the sealing station, the bag is positioned between heating elements or sealing bars. These elements are designed to heat-seal the open end of the bag, creating a secure and airtight seal.
Cooling and Cutting: Once the sealing process is complete, the sealed area may pass through a cooling section to ensure that the material solidifies and the seal becomes stable. After cooling, if applicable, a cutting mechanism separates the sealed bag from the continuous roll or material.
Final Product Discharge: The sealed and filled bags are then discharged from the machine, ready for further processing or packaging.
The sealing process is often controlled by a combination of temperature, pressure, and time parameters to achieve the desired seal quality. Depending on the type of sealing machine, additional features such as date coding, batch printing, and other customization options may be integrated into the overall system.
