Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example
[0024] Please see Figures 1-4 The present invention provides the following technical solution:
[0025] A fruit and vegetable preservation packaging device, comprising:
[0026] Packaging line 1;
[0027] The packaging mechanism includes a wrapping conveyor belt 2, a sealing conveyor belt 3, an upper sealing bag 4, a lower sealing bag 5, an extrusion plate 6, an extrusion cylinder 7, a hot melt block 8, and a cutting blade 18. The wrapping conveyor belt 2 is connected to the packaging line 1. The sealing conveyor belt 3 is located at one side of the wrapping conveyor belt 2. The upper sealing bag 4 and the lower sealing bag 5 are located at the upper end of the packaging line 1 through a belt exit mechanism. The extrusion plate 6 is fixedly connected to the lower inner wall of the packaging line 1 and is located at the close ends of the wrapping conveyor belt 2 and the sealing conveyor belt 3. The extrusion cylinder 7 is located at the upper end of the packaging line 1. The hot melt block 8 is fixedly connected to the lower end of the extrusion cylinder 7. The cutting blade 18 is located at one side of the hot melt block 8.
[0028] In a specific embodiment of this utility model, the wrapping conveyor belt 2 and the sealing conveyor belt 3 are two packaging conveyor belts. When the fruits and vegetables are at the upper end of the wrapping conveyor belt 2, the upper sealing bag 4 and the lower sealing bag 5 wrap the fruits and vegetables through the upper and lower ends. When the fruits and vegetables are conveyed to the upper end of the sealing conveyor belt 3, the packaging mechanism cuts and seals the upper sealing bag 4 and the lower sealing bag 5 to complete the fruit and vegetable packaging. Both the upper sealing bag 4 and the lower sealing bag 5 are pulled out from the sealing bag output cylinder. When the fruits and vegetables are conveyed to the upper end of the wrapping conveyor belt 2, they are conveyed to the upper end of the lower sealing bag 5 and moved forward by the wrapping conveyor belt 2 to the connection point of the wrapping conveyor belt 2 and the sealing conveyor belt 3. At this time, the packaging mechanism presses down and contacts the extrusion plate 6, so that the hot melt block 8 The lower sealing bag 5 and the upper sealing bag 4 are pressed down and melted together. When the hot melt block 8 presses down to connect the upper sealing bag 4 and the lower sealing bag 5, the cutting blade 18 cuts down the connection end of the upper sealing bag 4 and the lower sealing bag 5. At this time, the front end of the fruit and vegetable is sealed. The packaging mechanism moves upward and the fruit and vegetable continues to move forward until the packaging mechanism connects and cuts down the upper sealing bag 4 and the lower sealing bag 5. The fruit and vegetable in this section is sealed from front to back in a sealed packaging bag connected by the upper sealing bag 4 and the lower sealing bag 5. Through this device, the continuous fruit and vegetable wrapping, cutting and sealing operation is realized through an automated process, which greatly improves the packaging speed and the overall efficiency of the production line.
[0029] Please refer to the details. Figures 1-4 The upper end of the packaging line 1 is fixedly connected to a lifting support rod 11, the upper end of the lifting support rod 11 is fixedly connected to a drive cylinder 12, the output end of the drive cylinder 12 is fixedly connected to a lifting plate 13, the lower end of the lifting plate 13 is fixedly connected to a blade plate 17, and the cutting blade 18 is fixedly connected inside the blade plate 17.
[0030] In this embodiment: A drive cylinder 12 is fixedly connected to the upper end of the lifting support rod 11. The drive cylinder 12 serves as a power source, responsible for driving the lifting plate 13, which is fixedly connected to its output end, to move up and down. By controlling the action of the drive cylinder 12, the position of the lifting plate 13 can be precisely adjusted to adapt to the packaging needs of fruits and vegetables of different sizes and types. The cutting blade 18 is fixedly connected inside the blade plate 17. Thus, when the drive cylinder 12 pushes the lifting plate 13 downward, the cutting blade 18 also descends accordingly, accurately completing the cutting operation at the connection between the upper sealed bag 4 and the lower sealed bag 5.
[0031] Please refer to the details. Figures 1-4 The extrusion cylinder 7 has a pressure groove 14, and a pressure boosting plate 15 is provided in the pressure groove 14. The pressure boosting plate 15 is fixedly connected to the lower end of the lifting plate 13.
[0032] In this embodiment: to ensure that the sealing bags are evenly stressed during heat fusion, a pressure groove 14 is provided inside the extrusion cylinder 7. When the drive cylinder 12 pushes the lifting plate 13 downward, the pressure plate 15 also descends into the pressure groove 14 and applies appropriate pressure to the upper sealing bag 4 and the lower sealing bag 5. This design helps ensure that the sealing bags can be tightly bonded under uniform pressure during the heat fusion operation, thereby forming a strong sealing connection.
[0033] Please refer to the details. Figures 1-4 Multiple pressure springs 16 are fixedly connected to the lower end of the pressure plate 15 and the lower inner wall of the pressure groove 14.
[0034] In this embodiment: when the lifting plate 13 drives the pressure plate 15 to move downward, the pressure spring 16 begins to compress and generate a reaction force. These springs can flexibly adjust their compression degree according to different pressure requirements, thereby ensuring that the upper sealing bag 4 and the lower sealing bag 5 can be subjected to uniform and appropriate pressure during the heat fusion connection.
[0035] Please refer to the details. Figures 1-4 The upper end of the packaging line 1 is fixedly connected to two side heat melters 9, and the output end of the side heat melters 9 is located at the connection end of the upper sealed bag 4 and the lower sealed bag 5.
[0036] In this embodiment, two side heat-sealing machines 9 are located on both sides of the packaging line 1, and their output ends are precisely located at the connection end of the upper sealing bag 4 and the lower sealing bag 5. This arrangement can ensure that while the top and bottom are heat-sealed, the sides can also be fully heat-sealed, avoiding the problem of poor side sealing that may occur in traditional packaging methods.
[0037] Please refer to the details. Figures 1-4 One end of the wrapping conveyor belt 2 is equipped with a conveyor belt for transporting fruits and vegetables.
[0038] In this embodiment: the conveyor belt is designed to achieve seamless docking with the packaging conveyor belt 2, ensuring that fruits and vegetables can be smoothly transferred, reducing possible damage during transportation, and transporting the fruits and vegetables onto the packaging conveyor belt 2.
[0039] The working principle and usage process of this utility model: The wrapping conveyor belt 2 and the sealing conveyor belt 3 are two packaging conveyor belts. When the fruits and vegetables are at the upper end of the wrapping conveyor belt 2, the upper sealing bag 4 and the lower sealing bag 5 wrap the fruits and vegetables through the upper and lower ends. When the fruits and vegetables are conveyed to the upper end of the sealing conveyor belt 3, the packaging mechanism cuts and seals the upper sealing bag 4 and the lower sealing bag 5 to complete the fruit and vegetable packaging. Both the upper sealing bag 4 and the lower sealing bag 5 are pulled out from the sealing bag output cylinder. When the fruits and vegetables are conveyed to the upper end of the wrapping conveyor belt 2, they are conveyed to the upper end of the lower sealing bag 5 and are moved forward by the wrapping conveyor belt 2 to the connection point of the wrapping conveyor belt 2 and the sealing conveyor belt 3. At this time, the packaging mechanism presses down and contacts the extrusion plate 6, so that the hot melt block The hot melt block 8 presses down on the lower sealing bag 5 and the upper sealing bag 4, melting and connecting them. As the hot melt block 8 presses down to connect the upper sealing bag 4 and the lower sealing bag 5, the cutting blade 18 cuts down on the connecting end of the upper sealing bag 4 and the lower sealing bag 5. At this time, the front end of the fruit and vegetable is sealed, the packaging mechanism moves upward, and the fruit and vegetable continues to move forward until the packaging mechanism connects and cuts down on the upper sealing bag 4 and the lower sealing bag 5. This section of fruit and vegetable is then sealed from front to back in a sealed packaging bag connected by the upper sealing bag 4 and the lower sealing bag 5. Through this device, continuous fruit and vegetable wrapping, cutting, and sealing operations are achieved through an automated process, greatly improving the packaging speed and the overall efficiency of the production line.
