DETAILED DESCRIPTION

[0020] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0021] The present embodiment provides a fruit and vegetable crisp packaging and sealing machine. The utility model can drive the carrier frame 10 to rotate by setting a rotating structure 8, and can also limit and fix the carrier frame 10. By setting a cleaning mechanism 9, the plastic residue remaining on the carrier frame 10 can be scraped off. The rotating structure 8 and the cleaning mechanism 9 cooperate with each other to clean the plastic residue on the carrier frame 10, so that the sealing part of the packaging bag can be in a flat state, thereby ensuring normal sealing operation.

[0022] See also Figure 1 to Figure 4 A fruit and vegetable crisp packaging and sealing machine comprises a bottom plate 1, an upper surface of the bottom plate 1 is fixedly connected to an L-shaped plate 2, a first electric push rod 3 is installed on the top of the L-shaped plate 2, and a heating plate 4 is fixedly connected to the telescopic end of the first electric push rod 3.

[0023] A second electric push rod 5 is installed above the bottom plate 1 , and a supporting plate 6 is fixedly connected to the telescopic end of the second electric push rod 5 .

[0024] Two second electric push rods 5 are designed, one at the front and one at the back. The second electric push rods 5 can drive the supporting plate 6 to move up and down, and can increase the stability of the supporting plate 6 when it moves.

[0025] A limiting member 7 is arranged above the bottom plate 1 .

[0026] The limiting member 7 includes a limiting plate 701, the outer surface of which is fixedly connected to the upper surface of the base plate 1, four threaded holes 702 are provided inside the limiting plate 701, and a slide groove 703 is provided inside the limiting plate 701. The slide groove 703 can limit the movable plate 901, thereby improving the mobility stability of the movable plate 901.

[0027] A rotating structure 8 is provided on the outer side of the limiting plate 701 .

[0028] The rotating structure 8 includes a pull rod 801 , the outer surface of which is fixedly connected to a connecting plate 802 , the outer surface of which is fixedly connected to a rotating shaft 803 , and one end of the rotating shaft 803 away from the connecting plate 802 is fixedly connected to the outer surface of the supporting frame 10 .

[0029] The inner thread of the connecting plate 802 is connected with a threaded rod 804 , and the outer surface of the threaded rod 804 is threadedly connected with the threaded hole 702 . A cleaning mechanism 9 is provided inside the limiting plate 701 .

[0030] Rotate the threaded rod 804 to unscrew it from the threaded hole 702, and then rotate the pull rod 801 clockwise by 90 degrees. At this time, the pull rod 801 will drive the connecting plate 802, the rotating shaft 803 and the supporting frame 10 to rotate accordingly. Then screw the threaded rod 804 back into the threaded hole 702 to fix the position of the supporting frame 10. At this time, the flipping effect of the supporting frame 10 can be achieved.

[0031] The cleaning mechanism 9 includes a movable plate 901 , and a handle is fixedly connected to the right side of the movable plate 901 to facilitate the movement of the movable plate 901 .

[0032] The outer surface of the moving plate 901 slides with the inside of the slide groove 703 , and the outer surface of the moving plate 901 is fixedly connected with a scraper 902 .

[0033] The bottom surface of the movable plate 901 is fixedly connected with an elastic member 903 , and one end of the elastic member 903 away from the movable plate 901 is fixedly connected to the upper surface of the bottom plate 1 . The elastic member 903 is made of a spring and has elasticity and is retractable and resilient.

[0034] By moving the movable plate 901 downward, the scraper 902 can be driven to move downward. At this time, the movable plate 901 will compress the elastic member 903, causing the elastic member 903 to deform and generate upward elastic potential energy. When the movable plate 901 is released, the deformed elastic member 903 will drive the movable plate 901 to move upward, thereby achieving a rapid reset effect of the movable plate 901 and the scraper 902.

[0035] A carrier frame 10 is arranged above the bottom plate 1. The carrier frame 10 has four faces. Each time it rotates 90 degrees, the upward face can be directed toward the scraper 902, thereby facilitating the scraper 902 to scrape off the plastic on its outer surface.

[0036] Working principle: When the utility model is used, the fruit and vegetable crisp packaging bag that needs to be sealed can be placed on the carrier plate 6 first, and then the second electric push rod 5 is used to drive the fruit and vegetable crisps and the external packaging bag to move upward, so that the height of the packaging opening is above the carrier frame 10, and then the opening is moved to the carrier frame 10, and then the first electric push rod 3 can be started. At this time, the telescopic end of the first electric push rod 3 can drive the heating plate 4 to move downward. At this time, the heated heating plate 4 can heat and seal the opening of the packaging bag located on the carrier frame 10, and then it can be removed after heating. When the heating temperature of the heating plate 4 is too high due to unexpected factors, the plastic at the sealing part will melt, and the melted plastic liquid will adhere to the carrier frame 10. On the upper surface, it will quickly solidify on the carrier 10. At this time, it is necessary to rotate the threaded rod 804 to screw it out of the threaded hole 702, and then rotate the pull rod 801 clockwise ninety degrees. At this time, the pull rod 801 will drive the connecting plate 802, the rotating shaft 803 and the carrier 10 to rotate accordingly. Then, the threaded rod 804 can be screwed back into the threaded hole 702 to fix the position of the carrier 10, and then the movable plate 901 is pressed downward. At this time, the movable plate 901 will drive the scraper 902 to move downward and compress the elastic member 903 at the same time. When the outer surface of the scraper 902 contacts the outer surface of the carrier 10, the plastic adhered to its outer surface will be scraped off on the bottom plate 1, and a collection box can be used in advance for centralized collection and treatment.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
