[0024] The technical solutions of the present invention will be further described below in conjunction with the drawings and specific implementations.

[0025] figure 1 It is a schematic diagram of the specific implementation structure of the present invention. A fully automatic continuous stretch vacuum packaging machine includes a frame 1 on which a packaging system, a control system and a film unwinding device are arranged, wherein the packaging system includes:

[0026] It is set at one end of the frame and connected with the control system to stretch and shape the packaging film;

[0027] Connected to the control system, a material filling device for filling materials to be packaged after the stretching forming device on the frame;

[0028] It is connected with the control system and the vacuum pump 4 under the packaging machine at the same time, and is provided with a packaging device of the vacuum chamber 7;

[0029] It is connected with the control system and is provided with a cutting device for the transverse cutter 13 and the longitudinal cutter 14;

[0030] The stretch forming device includes a heating device and a forming device. The forming device is provided with a forming chamber 6, which is connected to a vacuum pump 4. The heating device is provided with a laminating heating plate. The main work of the stretch forming device is The flat stretchable film is laminated with a heating plate to increase the temperature of the film to increase the plasticity of the film, and then stretch the film into the same shape as the mold through compressed air and suction, which is convenient for subsequent heat sealing package.

[0031] The control system of the present invention is a servo closed-loop control system, including servo motors, PLC controllers, sensors and displays 8. The control system adopts the world’s leading servo closed-loop control technology with advanced pneumatic drive technology, plus stable and reliable mechanical transmission. Precisely control the filming and sealing of the equipment chain, which greatly reduces equipment maintenance costs. The sensor adopts a proximity sensor, which combines the photoelectric eye 17 on the side of the packaging device and the brake device 9 on the electrical box 10 to achieve automatic tracking and control , And the display adopts a true color touch screen, which is not only convenient for monitoring, but also convenient for inputting programs and instant operation;

[0032] The wrapping film unwinding device includes an upper film unwinding shaft 11 installed on the upper part of the frame 1 and a lower film unwinding shaft 5 installed on the lower end of the forming device on the frame 1.

[0033] A coding machine 12 is installed between the packaging device and the cutting device for printing codes and production dates on the packaging bags.

[0034] The electrical device of the control system is installed in the electrical box 10 on the rack 1, and the display 8 and the brake device 9 are installed on the electrical box 10.

[0035] A conveyor belt 16 is installed after the cutting device at the end of the rack 1 to convey the packaged goods, and a waste collection system 15 for recycling waste is also installed above the conveyor belt 16 at the end of the rack 1.

[0036] The frame 1 and most of the devices are made of stainless steel, which meets the safety requirements of food production.

[0037] A lifting mechanism 2 is provided on the frame 1 below the vacuum chamber 7.

[0038] The present invention mainly uses polyethylene coils as packaging materials, through heating forming, filling goods, sealing, cutting, vacuum-tight packaging of goods in bags and other operations. It can be used for food, grain and other items such as dried tofu, Packaging of melon seeds, peanuts, biscuits, aquatic products, meat, spices, tea, chicken feet and other food and snack foods, as well as packaging of electronic products such as hard drives, LEDs, resistors, capacitors, bearings, screws and other mechanical parts. A high-efficiency filter device is installed at the entrance of the compression control device. After use, all exhaust gas is filtered and discharged to ensure that the filling room and the air in the workshop are clean during the filling production of the equipment, and the sterility of the product is greatly improved Performance and reduce the pollution of compressed air to the operating workshop.

[0039] The key parts adopt lubrication-free sliding bearings or oil-free sliding bearings, which are simple to install and easy to replace. Moreover, the equipment bearings do not need to be refueled for life, which completely eliminates the risk of product contamination by oil. A variety of different products and different packaging forms can be packaged on the same equipment, such as vacuum packaging, modified atmosphere packaging, double-sided stretch packaging, hard box packaging, etc.

[0040] The specific operation process of the present invention includes the following:

[0041] 1. Lower film unwinding: the lower film is installed on the lower film unwinding shaft 5, the clamp on the chain clamps the edge of the lower film, and the operation of the chain drives the lower film to move forward, in order to ensure the tension of the lower film during operation It is stable, and a tension adjustment device is installed at the unwinding place.

[0042] 2. Stretch forming: When the lower film runs to the stretch forming plate in the forming chamber 6, the lower film is preheated by the heating plate, and then stretched.

[0043] 3. Upper film unwinding: the upper film is installed on the upper film unwinding shaft 11, through the tension roller, the photoelectric eye 16 device and the guide roller, and the lower film is converged and heat-sealed at the heat-sealing plate, which is guaranteed during operation The tension of the film is smooth, and a tension adjustment device is installed at the unwinding place.

[0044] 4. Heat sealing device: After the upper and lower films are merged, the heat sealing device first seals the upper and lower films, and then vacuums the upper and lower air through the vacuum pump 4, and then the upper heat sealing plate heats the film to make the upper and lower films in Heat sealed together under pressure to ensure that the product does not leak after leaving the heat sealing plate.

[0045] 5. Date printing: The coding machine 12 codes the packaging bag. According to different requirements, the method of printing the date is different, and the position of the device for printing the date is also different. The printing with ribbon is used before the heat sealing plate, and the ink is sprayed. The printed one is behind the heat sealing plate.

[0046] 6. Slitting: The entire film with the product needs to be slit in both the horizontal and vertical directions, and multiple products after packaging are slit into a single product.

[0047] 7. Sterilization: the packaged products are sterilized in the sterilization pot.

[0048] The invention has complete functions and high degree of automation, especially when packing naked oats and other food crops, it is not only clean and not easy to cause pollution, but also has high packing efficiency, neatness and tightness, and uniform finished product specifications.
