Composition of automatic thermoforming vacuum packaging machine
Automatic thermoforming vacuum packaging machine is mainly composed of 10 parts:
● Base film feeding system: ensure that the base film is installed in place, runs stably and is not biased.
● Thermoforming system: the forming studio ensures that the base film is formed quickly, accurately and completely.
● Filling area: it can be filled manually, or it can be automatically filled with automatic filling machines, multi-head scales and other automatic feeding equipment.
● Touch screen and PLC: most of the machine settings and operations can be completed through the touch screen, and faults can be found and eliminated.
● Cap film feeding system: the cap film is the upper film and the sealing film.The cap film can be a light film (without printing) or a color film. If it is a color film, the machine will be equipped with a high-precision photoelectric tracking system to ensure that the film is smooth and accurate, and the desired packaging effect is achieved.
● Vacuum sealing system: vacuum sealing studio, to ensure high vacuum and fast, tight sealing quality.
● Pneumatic system: the pneumatic system is the power source of the forming and vacuum sealing studios, ensuring that the upper and lower molds are tightly and neatly combined.
● Slitting system: generally, the cross-cutting knife system is used for horizontal cutting, and then the longitudinal cutting knife system is used for longitudinal cutting, and finally the finished product is output. In special cases, such as when using hard film or when there are special requirements for packaging, an integrated punching system is used to complete the punching in one go.
● Waste film rewinding system: the cut waste film is recycled by this system, which is more environmentally friendly and easy to handle.
● Inkjet coding system: realizes the printing of product information, date information, etc. It can be equipped with an inkjet printer or a laser printer.
Working principle of fully automatic stretch film packaging machine (thermoforming vacuum packaging machine)
The working principle of the fully automatic stretch film packaging machine (thermoforming vacuum packaging machine) is to stretch the lower film in the forming studio, load the package into the formed lower mold cavity, then perform vacuum or vacuum inflation in the vacuum sealing studio, and heat-seal the upper film with the lower film, and then divide the package through the cross-cutting knife system and the longitudinal cutting knife system. Finally, the finished package will be transported to the next process along the conveyor belt, and the remaining waste film material will be recycled by the waste film winding system.
The thermoforming vacuum packaging machine must use a forming mold. After the lower film enters the forming studio, it is formed into the shape of the container through heating and vacuum negative pressure stretching and other technologies, and the package is loaded into the formed lower mold cavity, and finally the package is sealed. The size and shape of the lower film are completely determined by the forming mold. We will design the mold according to customer needs and product characteristics.
Application scope of fully automatic thermoforming vacuum packaging machine
Automatic thermoforming vacuum packaging machine is widely used in vacuum, gas-controlled and skin packaging of various foods and non-foods, including:
1. Meat and poultry products: including fresh or frozen pork, beef, steak, cold fresh meat, chicken, duck and goose meat, goose liver, braised eggs, chicken wings, braised meat products, quail eggs, ham and sausage products, etc.;
2. Fish and seafood products: including frozen fish fillets, whole fish of various sizes, salmon meat, shellfish, crabs, frozen shrimps, kelp processed products, crayfish, etc.;
3. Pasta bakery products: including various types of bread, sandwiches, noodles, pizza, boxed lunch fast food, etc. that require inflatable packaging;
4. Vegetable and fruit products: including various types of pickles, kimchi, freeze-dried vegetable products;
5. Snacks, seasonings, sauces, hot pot ingredients, ketchup, etc.
6. Pet food
7. Medical devices: disposable masks, swabs, surgical gowns, syringes, etc.
304 Stainless steel frame structure
1. The structure has high strength and corrosion resistance. The screw holes in each fixed position are processed by high-precision laser at one time to ensure the accuracy of assembly and make the whole machine run smoothly.
2. More expandability, when the packaging form needs to be upgraded, relevant parts can be added at any time according to the packaging requirements.
Four-axis linkage lifting device
1. The lifting device is made of 6061 aviation aluminum alloy, which increases the stability and strength of the components. The sliding parts adopt imported high wear-resistant linear bearings, which are accurate in positioning and stable in operation. The lifting height can be adjusted arbitrarily according to the thickness of the product packaging. Without changing the running speed, the lifting distance is shortened to improve the packaging speed of the entire machine.
2. The parts are inlaid with graphite copper sleeves to increase lubrication, reduce abrasion and extend the service life. In addition, the graphite copper sleeve is extremely pressure-resistant, which ensures the sealing of the molding chamber and the vacuum chamber.
Electronic magnetic pre-tightening device
1. Using electromagnetic brake, the brake is stable and the force is even, avoiding the phenomenon of wrinkling and curling of the packaged products.
2. The digital display shows that the tightening force is adjustable. The key can be adjusted conveniently and intuitively according to the thickness, flexibility and softness of the packaging film to achieve the best packaging effect.
Electrical System
1. The intelligent control system adopts the German Siemens brand uniformly, and the control points are responsive and cooperative. The temperature, time, and vacuum pressure of each part are displayed on the computer screen, and it has its own fault detection function.
2. Adopting German Siemens high inertia servo motor and driver, the chain positioning is accurate and running fast.
Intelligent operating system
1. Touch screen operation, automatic program control, graphic display of the entire running status, automatic detection of the cause of failure, easy to operate and maintain the equipment.
2. The intelligent and humanized operation screen is simpler and clearer. Each parameter can be adjusted appropriately according to different products, and different product process parameters can be stored. One-click calling saves time and effort.
Safety protection system
1. All transmission parts; parts with temperature; cutting and moving parts are equipped with protection devices, and magnetic contact switches are installed. Once the protection devices are not in place or the original machine protection devices are not in place, the machine will stop immediately.
2. The equipment itself is equipped with emergency stop switches in different positions, so as to stop the machine in time when an accident occurs.
3. It is forbidden to reach out hands, feet, arms and other parts with a beam switch, once it is sensed, it will stop immediately.
Waste film recycling system
1. The waste recycling has an intelligent detection device, which can automatically adjust the operating speed according to the length of the waste film.
2. The device is noise-free, easy to collect the film, equipped with 150W power, indirect operation, saving power consumption.
Forming and heat sealing mold
All molds can be quickly replaced, and multiple sets of molds can be exchanged on a set of equipment to facilitate the packaging of multiple products.
Multifunctional slitting system
According to different products, it can realize round corner slitting, easy tearing, hanging holes, serrated slitting, overall punching and other applications, and the speed of cutter replacement is quick and easy.
