[0001] This utility model belongs to the field of corn storage technology, specifically a modified atmosphere packaging device for fresh corn to lock in freshness. Background Technology

[0002] Modified atmosphere packaging (MAP) for fresh corn is a packaging device specifically designed for preserving fresh corn. It alters the internal gas environment by replacing ordinary air with a specific mixture of gases (such as nitrogen and carbon dioxide), thereby inhibiting the corn's respiration and the growth and reproduction of microorganisms. This effectively extends the shelf life of fresh corn, maintaining its freshness, taste, and nutritional value. At the same time, this packaging method also prevents the corn from being contaminated by the external environment, ensuring food safety.

[0003] Existing modified atmosphere packaging (MAP) devices for fresh corn generally require specific molds to position the corn boxes accurately, ensuring proper packaging. However, different sizes of corn boxes require different molds, which are typically integrated into the packaging device, making replacement difficult and limiting their applicability to various corn boxes. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a modified atmosphere packaging freshness-locking device for fresh corn, which solves the problem that in the use of existing modified atmosphere packaging freshness-locking devices for fresh corn, different molds need to be changed according to the actual situation because the size of fresh corn packaging boxes of different specifications varies. However, the existing molds are generally installed as one piece on the packaging freshness-locking device, which makes it difficult to change them and makes it difficult to be applicable to fresh corn packaging boxes of different specifications, thus limiting its scope of application.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modified atmosphere packaging freshness-locking device for fresh corn, comprising a base, four support legs fixedly connected to the top of the base, a main body of the modified atmosphere packaging freshness-locking device fixedly connected to the top of the four support legs, a box body provided on the top of the base, fixing plates fixedly connected to both sides of the inner wall of the box body, two round holes provided on the fixing plates, two fixing plates in total, a mold provided on the top of the two fixing plates, and four mold holes provided on the mold.

[0006] The bottom of the mold is fixedly connected to four cylinders, and the bottom of each cylinder is fixedly connected to a circular plate. The bottom of the two fixed plates is provided with a movable plate. The movable plate has four circular holes and four square holes, which are connected to the circular holes. The box body is fixedly connected to a shell, and a screw is threaded onto the shell. One end of the screw is rotatably connected to a movable plate, and two movable columns are fixedly connected to the movable plate.

[0007] As a further embodiment of this utility model: the end of the movable column away from the moving plate passes through the box body and is fixed to the movable plate, and the end of the screw away from the moving plate is fixedly connected to a knob.

[0008] As a further embodiment of this utility model: both sides of the movable plate are fixedly connected with slide bars, and a slide groove is opened inside the box body corresponding to the position of the slide bar, and the slide bar is slidably connected inside the slide groove.

[0009] As a further embodiment of this utility model: a support plate is fixedly connected to one side of the base, and two triangular plates are fixedly connected to the bottom of the support plate, and the triangular plates are fixed to the base.

[0010] As a further embodiment of this utility model: a motor is fixedly connected to the top of the support plate, and a lead screw is fixedly connected to the output section of the motor.

[0011] As a further embodiment of this utility model: both sides of the top of the base are fixedly connected to fixing strips, the lead screw is rotatably connected to the two fixing strips through bearings, and a fixing rod is fixedly connected between the two fixing strips.

[0012] As a further embodiment of this utility model: four uprights are fixedly connected to the bottom of the box body, two of which are fixedly connected to a second slider at their bottom ends, and the other two are fixedly connected to a first slider at their bottom ends. The second slider is threadedly connected to a lead screw, and the first slider is slidably connected to a fixed rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This modified atmosphere packaging freshness-locking device for fresh corn comprises a mold, a cylinder, a circular plate, a fixed plate, a square hole, a circular hole, and a screw. When the mold needs to be disassembled, rotating the knob drives the screw to rotate. Since the screw is threaded onto the housing, it moves as it rotates, causing the moving plate, movable cylinder, and movable plate to move. When the circular hole aligns with the circular plate, the movable plate no longer obstructs the circular plate, allowing the mold to be disassembled. When the mold needs to be installed, it is placed inside the box, limiting its horizontal position. The fixed plate supports the mold, and the circular plate passes through the circular hole. At this point, rotating the knob in the opposite direction... The knob drives the screw to rotate, which in turn moves the movable plate, the movable column, and the movable plate. When the circular hole moves to a position where it is misaligned with the circular plate, the cylinder is located inside the square hole. Since the width of the square hole is equal to the diameter of the cylinder but smaller than the diameter of the circular plate, the movable plate can block the circular plate, thus limiting the vertical direction of the mold and completing the mold installation. This device uses a modular mold, and the mold can be disassembled and assembled simply by turning the knob. The operation is simple and quick. By changing the mold, the mold hole can be changed to a different size, which can be used for different specifications of fresh corn packaging boxes, thereby expanding the scope of application.

[0015] 2. This modified atmosphere packaging (MAP) device for fresh corn, consisting of a lead screw, a motor, and a second slider, allows for easy operation. When the device is needed, the fresh corn packaging box is placed inside the mold hole. The motor is then activated, driving the lead screw to rotate. Since the second slider is threaded onto the lead screw, its rotation moves the second slider and the box together. Once the box, carrying the fresh corn, reaches the bottom of the MAP device, the device is activated to perform MAP. This device automatically moves the fresh corn packaging box to the bottom of the MAP device for loading, eliminating the need for manual loading and significantly reducing the workload of staff.

Detailed Implementation

[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0022] like Figure 1-4 As shown, this utility model provides a technical solution: a modified atmosphere packaging freshness-locking device for fresh corn, including a base 1, four support legs 11 fixedly connected to the top of the base 1, the main body 10 of the modified atmosphere packaging freshness-locking device fixedly connected to the top of the four support legs 11, a box 7 provided on the top of the base 1, and fixed plates 18 fixedly connected to both sides of the inner wall of the box 7. Two round holes 23 are opened on the fixed plates 18. The end of the movable column 27 away from the movable plate 17 passes through the box 7 and is fixed to the movable plate 24. The end of the screw 14 away from the movable plate 17 is fixedly connected to a knob 15.

[0023] There are two fixed plates 18. A mold 19 is set on the top of the two fixed plates 18. The mold 19 has four mold holes 20. Four cylinders 21 are fixedly connected to the bottom of the mold 19. A circular plate 22 is fixedly connected to the bottom of the cylinders 21. A movable plate 24 is set at the bottom of the two fixed plates 18. The movable plate 24 has four circular holes 25. Slide strips 28 are fixedly connected to both sides of the movable plate 24. A groove 29 is opened inside the box body 7 corresponding to the position of the slide strip 28. Because of the slide strip 28 and the groove 29, when the movable plate 24 moves, the slide strip 28 will slide inside the groove 29. The groove 29 can support and limit the slide strip 28 and the movable plate 24, improve the stability of the movement of the movable plate 24, and the slide strip 28 is slidably connected inside the groove 29.

[0024] Four square holes 26 are provided on the movable plate 24, which are connected to the circular holes 25. A shell 16 is fixedly connected to the box body 7, and a screw 14 is threadedly connected to the shell 16. One end of the screw 14 is rotatably connected to a movable plate 17. A support plate 12 is fixedly connected to one side of the base 1. Two triangular plates 13 are fixedly connected to the bottom of the support plate 12. The triangular plates 13 can support the support plate 12 and the motor 9, thereby improving the stability of the support plate 12 and the motor 9. The triangular plates 13 are fixed to the base 1. The motor 9 is fixedly connected to the top of the support plate 12. A lead screw 8 is fixedly connected to the output section of the motor 9. The lead screw 8 can automatically move the fresh corn packaging box to the bottom of the modified atmosphere packaging freshness-locking device body 10 for feeding by rotating the lead screw 8, without the need for manual feeding, thereby greatly reducing the labor intensity of the staff.

[0025] Two movable columns 27 are fixedly connected to the movable plate 17. Fixed strips 2 are fixedly connected to both sides of the top of the base 1. The lead screw 8 is rotatably connected to the two fixed strips 2 through bearings. A fixed rod 3 is fixedly connected between the two fixed strips 2. Because of the fixed rod 3, when the box 7 moves, the first slider 4 will slide on the fixed rod 3. The fixed rod 3 can limit and guide the first slider 4 and the box 7, thereby improving the stability and accuracy of the movement of the box 7. Four uprights 6 are fixedly connected to the bottom of the box 7. The bottom ends of two uprights 6 are fixedly connected to the second sliders 5, and the bottom ends of the other two uprights 6 are fixedly connected to the first sliders 4. The second sliders 5 are threaded to the lead screw 8, and the first sliders 4 are slidably connected to the fixed rod 3.

[0026] The working principle of this utility model is as follows:

[0027] When the device is needed, place the fresh corn packaging box inside the mold hole 20. At this time, start the motor 9 to drive the lead screw 8 to rotate. Since the second slider 5 is threadedly connected to the lead screw 8, when the lead screw 8 rotates, it will drive the second slider 5 and the box body 7 to move. When the box body 7 moves the fresh corn to the bottom of the modified atmosphere packaging freshness-locking device body 10, the modified atmosphere packaging freshness-locking device body 10 can be started to perform modified atmosphere packaging on the fresh corn. When the mold 19 needs to be disassembled, turn the knob 15 to drive the screw 14 to rotate. Since the screw 14 is threadedly connected to the housing 16, when the screw 14 rotates, it will move. The screw 14 will drive the moving plate 17, the movable column 27, and the movable plate 24 to move. When the circular hole 25 moves to align with the circular plate 22, the movable plate 24 will no longer block the circular plate 22, and the mold 19 can be disassembled.

[0028] When the mold 19 needs to be installed, the mold 19 is placed inside the box 7 to limit the horizontal direction of the mold 19. The fixing plate 18 will support the mold 19, and the circular plate 22 will pass through the circular hole 23 and the circular hole 25. At this time, the knob 15 is rotated in the opposite direction to drive the screw 14 to rotate. When the screw 14 rotates, it will drive the moving plate 17, the movable column 27, and the movable plate 24 to move. When the circular hole 25 moves to the point where it is misaligned with the circular plate 22, the column 21 is located inside the square hole 26. Since the width of the square hole 26 is equal to the diameter of the column 21 but smaller than the diameter of the circular plate 22, the movable plate 24 can block the circular plate 22, thereby limiting the vertical direction of the mold 19 and completing the installation of the mold 19.
