[0002] Fruits and vegetables, that is, the general term for vegetables and fruits, are an important and indispensable part of our daily diet. They not only taste delicious but also are rich in various nutrients beneficial to the human body, such as vitamins, minerals, dietary fiber, and various antioxidant substances, etc. Vegetables mainly refer to a category of plants that can be cooked into food and are one of the essential foods in people's daily diet. Vegetables usually contain relatively low calories but are rich in vitamins, minerals, and dietary fiber, which helps promote intestinal peristalsis and maintain good health. Fruits refer to the edible plant fruits that are juicy and mainly have a sweet and sour taste. Fruits not only contain rich vitamins (especially vitamin C and vitamin A), minerals (such as potassium and magnesium), and dietary fiber but also contain various bioactive substances, such as flavonoids and polyphenols, etc. These substances have various health care functions for the human body, such as antioxidant and anti-inflammatory effects.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0020] Refer to Figures 1-4 , a fresh-keeping film covering device for fruits and vegetables, comprising a workbench 1 placed on the ground. A fixed plate 2 is fixedly connected to the top end of the workbench 1. A right fixed frame 3 is fixedly connected to the outer wall of the fixed plate 2. A fresh-keeping film 4 is arranged on the right fixed frame 3. Symmetrically distributed fixed columns 5 are fixedly connected to the outer wall of the fixed plate 2. The fixed columns 5 are connected to a lower pressing roller 6 through a pressing structure. A support frame 7 is fixedly connected to the top end of the workbench 1. The support frame 7 is connected to a cutting tool 8 through a cutting structure. A sliding groove 9 is opened on the outer wall of the fixed plate 2. A left fixed frame 10 is slidably connected to the inner wall of the sliding groove 9. A threaded hole 11 is opened on the outer wall of the left fixed frame 10. A bolt 12 is threadedly connected to the threaded hole 11. A fixed rod 13 is rotatably connected to the right fixed frame 3. The end of the fixed rod 13 facing the left fixed frame 10 is also provided with a threaded hole 11.
[0021] It should be noted that the electric push rod 19 is a prior art. The specific model and specification need to be selected according to the actual specifications of the device. The specific selection calculation method uses the prior art in this field, so it will not be elaborated here.
[0022] Among them, the length of the bolt 12 can completely penetrate the left fixing frame 10 and be connected to the threaded hole 11 on the fixing rod 13.
[0023] Furthermore, the pressing structure includes symmetrically distributed connecting frames 14, sliding columns 15, sliders 16, springs 17, and upper pressing rollers 18. The connecting frames 14 are fixedly connected to the fixing columns 5. The sliding columns 15 are fixedly connected to the inner walls of the connecting frames 14. The sliders 16 are slidably connected to the sliding columns 15. Both ends of the spring 17 are fixedly connected to the sliders 16.
[0024] Among them, under the action of the spring 17, the lower pressing roller 6 and the upper pressing roller 18 can approach each other and abut against each other, clamping the plastic wrap 4. At the same time, the lower pressing roller 6 and the upper pressing roller 18 can be separated to facilitate the plastic wrap 4 to pass through.
[0025] Furthermore, the sliders 16 are slidably connected to the inner walls of the connecting frames 14. Both ends of the lower pressing roller 6 are rotatably connected to the lower sliders 16. Both ends of the upper pressing roller 18 are rotatably connected to the upper sliders 16. The spring 17 is arranged in the middle of the sliders 16.
[0026] Among them, the pressing structure pulls the sliders 16 arranged on the sliding columns 15 and makes them approach each other through the spring 17. At the same time, the sliders drive the lower pressing roller 6 and the upper pressing roller 18 to approach each other, clamping the pulled-out plastic wrap 4 to avoid losing the starting end.
[0027] Furthermore, the cutting structure includes an electric push rod 19, a limiting groove 20, a working groove 21, and a knife groove 22. The electric push rod 19 is fixedly connected to the top of the support frame 7. The limiting grooves 20 are symmetrically distributed and arranged on both sides of the inner wall of the support frame 7. The working groove 21 is arranged at the top of the workbench 1. The knife groove 22 is arranged at the bottom end of the inner wall of the working groove 21.
[0028] Among them, for the cutting structure, by starting the electric push rod 19, the electric push rod 19 drives the tool 8 to move up and down. The tool 8 slides up and down along the limiting groove 20. When the tool 8 moves down to the lowest position, it can be inserted into the knife groove 22.
[0029] Furthermore, the telescopic end of the electric push rod 19 penetrates the outer wall of the support frame 7 and is connected to the top end of the tool 8. The tool 8 is slidably connected to the inner wall of the limiting groove 20. The position of the knife groove 22 is adapted to the position of the tool 8.
[0030] The limiting groove 20 is arranged all the way to the bottom end of the working groove 21 , so that the tool 8 can enter the working groove 21 , so that the tool 8 can be in closer contact with the bottom surface of the working groove 21 , and the cutting is faster.
[0031] Working principle: When it is necessary to wrap fruits and vegetables, first place the fruits and vegetables on the working groove 21 on the workbench 1, then tighten the bolt 12 so that the bolt 12 leaves the threaded hole 11, and at the same time, move the left fixing frame 10 to move leftward along the slide groove 9, and then insert the cling film 4 onto the fixing rod 13, and then insert the bolt 12 into the threaded hole 11 on the left fixing frame 10 to complete the replacement of the cling film 4, and then find the beginning of the cling film 4, guide it through the gap between the upper pressing roller 18 and the lower pressing roller 6, and wrap it. After wrapping, start the electric push rod 19, the electric push rod 19 drives the cutter 8 to move up and down, and the cutter 8 slides up and down along the limiting groove 20, and the cutter 8 cuts the cling film 4 downward. The opening of the cut cling film 4 is firmly pressed in the middle by the upper pressing roller 18 and the lower pressing roller 6, so that it is no longer necessary to find the beginning of the cling film 4, thereby avoiding damage to the cling film 4 caused by improper operation, and no longer directly contacting the cutter 8, which greatly avoids cuts to the hands, and is easier to operate.
[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
