The design principle of fruit and vegetable packaging machines is mainly based on improving packaging efficiency and quality, while meeting the market's packaging needs for fruits of different sizes and shapes. This type of packaging machine usually includes multiple parts such as conveying system, sorting system, packaging system, and control system, aiming to achieve efficient and reliable fruit and vegetable packaging process.

Introduction to the Four Major Systems of Fruit and Vegetable Packaging Machine:

1. Conveyor system: The conveyor system is responsible for transporting the fruits and vegetables to be packaged from the supply end to the packaging area. In order to accommodate fruits and vegetables of different sizes and shapes, the conveyor belt is designed with adjustable height to accommodate the height differences of different fruits and vegetables. In addition, the conveying system also has automatic control function, which can automatically adjust the conveying speed according to the adjustment of packaging speed.

2. Sorting system: The sorting system is used to classify and sort the fruits and vegetables to be packaged. Through photoelectric sensors and image recognition technology, fruits and vegetables can be accurately detected and classified. The sorting system should have fast response and accuracy, and be able to automatically sort out unqualified fruits and vegetables to ensure the quality of packaged fruits and vegetables.

3. Packaging system: The packaging system is the core part of the vegetable packaging machine, responsible for packing fruits and vegetables into packaging. When designing, adjustable packaging and filling devices are used to accommodate the packaging needs of different shapes and sizes of fruits and vegetables. The packaging system should have efficient and stable packaging speed, and ensure that fruits and vegetables are not damaged during the packaging process.

4. Control system: The control system is the brain of the entire vegetable packaging machine, responsible for monitoring and controlling the operation of various parts. The control system should have automatic control function and be able to achieve automated packaging process according to the set parameters. Through the coordination of sensors and actuators, the control system can monitor and adjust the transportation, sorting, and packaging processes of fruits and vegetables in real time, ensuring the smooth progress of the entire packaging process.

Analysis of the Composition Device of Fruit and Vegetable Packaging Machine:

1. The fully automatic packaging machine adopts Panasonic PLC intelligent control system to control the operation of the whole machine, which runs more stably and can adjust the setting parameters without stopping the machine. The whole machine is controlled by electronic touch screens in both Chinese and English languages, with a human-machine interface display. A large-sized touch screen is used to control the packaging process of the packaging machine, accurately and conveniently controlling key parameters such as packaging speed and temperature.

2. Linked film rolling axis, using multiple linked film rolling axes to coordinate the mold pulling process, adapting to more film rolling materials and making film rolling smoother. The roll film shaft is fixed by inflation expansion, making mold installation and removal very convenient.

3. Electronic control components: All electrical control modules of the whole machine are programmed by software to achieve reliable quality and easy maintenance. Equipped with Schneider/Panasonic electronic controllers, three-phase multi-stage speed control, bag length can be set and cut in one step, saving time and packaging film.

4. The packaging machine uses a customized metal bag maker: the stretching device enters the bag maker through the stretching mold, and the film is folded on both sides of the metal panels to form a bag shape. The bag shape is beautiful and flat.

5. The independent PID temperature control system controls the sealing area, heats the double-sided turntable for sealing, and seals the back of the packaged product. Two sets of sealing wheels are used for mold drawing, ensuring the accuracy and stability of the mold.

6. The end sealing cutting area is equipped with high-strength and hard materials to create a rotating and constant temperature heat sealing cutting blade, which seals the front and rear ends of the packaged product, effectively avoiding curled edges or loopholes at the sealing position.

7. The transmission structure of the entire packaging equipment uses traditional and simple mechanical transmission devices, with a simple transmission system that is more reliable, has strong operational coordination, and is easier to maintain.
