Technical Analysis of Thermoforming Plastic Cup Packaging Equipment

Thermoformed plastic cup packaging machine is widely used

In recent years, in the world, thermoforming plastic cup packaging machines (ie packaging machines for cupping, labeling, filling, heat-sealing, and slitting integration) have made many important advancements in technology, and thermoformed plastic cups The cost of packaging is very low. Compared with other packaging forms, it has obvious advantages, and it has obtained more and more extensive applications. The reasons are as follows:
1. In combination with labeling (circumference or side labeling) technology, the decorative effect of product packaging is greatly improved, which is very beneficial to the sales of the product.
2. The application scope of this packaging machine has been continuously expanding, and in many new areas, thermoforming plastic cup packaging machines have also been used, such as long-term yogurt, lactic acid beverages, student milk, and baby food.
3. The progress made in the "green" and "environmentalized" aspects of thermoformed plastic cup packaging machines has enabled it to continuously replace other forms of packaging and gain greater opportunities for development.
4. The thermoformed plastic cup packaging machine can be tailored according to the customer's unique requirements for the product, and can meet the customer's specific requirements in the most economical way.
As the well-known supplier of packaging machinery in the dairy industry, Hassier AG in Germany is mainly represented by the following aspects:
Hessian company in Germany and the FDA committee jointly developed a sterile plastic cup packaging technology and used steam as a bactericidal medium to truly achieve "green", "environmental friendly" and "no pollution." At the same time, Hasiya also developed a manufacturing technology that combines plastic cups and plastic bottles so that one device can be used to make cups (such as conventional plastic cups), and it can also be used to make bottles. The typical model is THIS type multipurpose machine from Hasiya.

The technical features of the Hessian THM yogurt filling machine are:
1. The supply of packaging material The unique design of the packaging material supply device, so that the maximum diameter of the packaging material up to 1200mm. The pre-stretching device and the tension adjusting roller ensure smooth and even feeding of the package material.
2. Preheating of packaging materials The contact ring heating plate distributes the heat evenly. The heating plate can precisely control the temperature and heat only the molding area. This avoids deformation of the sealing area and guarantees a high quality sealing effect. In addition, the package material feeding system in the subsequent process can always be in an accurate working state.
3. Plastic cup molding During molding, the servo motor-driven upper die first pre-stretches the preheated package material so that the thickness of the cup bottom and the cup wall are uniform, and the final molding is performed by aseptic compressed air.
4. How the cup lid opens According to the user's needs and the characteristics of the packaging materials, a variety of different cup lid opening methods can be designed. For example, the cup lid can be left unsealed and the like.
5. Filling system Filling system has the following characteristics: process precision, accurate filling, diversified design, and easy operation. It can solve the filling problem of various products with different characteristics and meet various packaging needs.
The intelligent servo-driven plunger type filling device is equipped with a membrane type control valve. Even if the viscosity and temperature of the product change within a large range, a satisfactory filling effect can be achieved.
Diversified feeding methods and filling head designs can meet a wide range of packaging needs. For materials containing granules, the uniquely designed device cuts the material after each filling to empty the filling head, ensuring that the product does not come into contact with the sealing area.
Automatic in-situ cleaning of CIP and steam sterilization SIP systems greatly shortens the time required to convert packaged products and prevents operators from contacting corrosive chemicals.
The adjustment of the filling volume can be carried out continuously by the HEISIAN PROMECON-H PLC microcomputer system.
6. Positioning of the marking mark The marking or marking of the marking on the lid can be precisely positioned on the lid by a proprietary mechanism.
7. Feeding the lid material The feed of the lid material includes a pretensioning device with a maximum diameter of 400 mm.
8. Heat sealing Because the temperature and pressure of the heat seal can be precisely adjusted, a uniform and ideal heat sealing effect can be achieved. When the machine is stopped for a short period of time, the heat seal plate will be cooled, so the residual heat of the radiation will not affect the product and the sealing area.
9. Driving of packaging materials Clamp drivers driven by independent electromechanical servos control the acceleration or deceleration of the packaging material. The parameters of various packaging materials and products are stored in the computer, so the machine operates at the highest speed and guarantees uniform heat sealing quality.
10. Slicing and cutting of plastic cups The multi-functional cutting knife can be divided into single cups, double cups, four cups or six cups, etc., and the change of the slitting form takes only a few seconds to complete. . The slitting tool can minimize the amount of waste, and only the star and two small fine edges between the two cups are not used. At the same time, the equipment also includes devices that generate a break-line (pre-scratched or punched, easy to open).
11. Man-machine dialogue control method The PROMECON-H PLC microcomputer system used by Hassiya is designed specifically for packaging machines, and other types of control systems can also be configured according to the needs of users. In order to achieve rapid conversion of products or packaging materials, a large number of programmed programs are stored in the memory. Operating the keyboard makes the adjustment of production parameters and storage records particularly convenient and flexible. The display of pure language on the screen is clear and clear. And equipped with a printer, you can print out a variety of production data.
12. Labeling System The labeling system can provide a circumference labeling system and also provides an exquisite side labeling system.
Hisia's new technology ensures that a wide range of flavored products can be filled at the same time during cup or bottle production, and different labels can be applied at the same time. The European market has shown that such products are extremely attractive to children and adolescents. If it is necessary to extend the product's shelf life, Hyssion can additionally provide UVC sterilizers and sterile protection channels, as well as fully sterile plastic cup forming and filling equipment.
The Hysteria THM Yoghurt filling machine uses steam sterilization, which has the following advantages compared to other aseptic packaging technologies that use hydrogen peroxide as a sterilizing medium:
● Pure natural vapor substitutes hydrogen peroxide for sterilization without any environmental pollution;
● There is no need to worry about the effect of residual bactericidal media on product color, flavor, quality, and consumers;
● Low operating costs;
● sterilization efficiency up to 106.
At present, thermoformed plastic cup packaging machines are mainly used for the packaging of conventional yoghurt, but with the development of domestic yoghurt market and the emergence of new products, new type of aseptic plastic cup packaging will gradually enter the Chinese market and become a Chinese dairy product. Enterprises provide more advanced packaging technology.
