Description

Technical Field

[0001] This utility model relates to the field of flexible packaging for king oyster mushrooms, specifically a flexible packaging device for king oyster mushrooms. Background Technology

[0002] King oyster mushrooms are a rare new variety of edible fungi that integrates culinary, medicinal, and therapeutic uses. The flesh of king oyster mushrooms is thick and tender, especially the dense, firm, milky-white stem, which is entirely edible. The stem is even crisper and more refreshing than the cap, earning it the nicknames "King of Oyster Mushrooms" and "Scallop Mushroom." It has an almond-like aroma and a texture similar to abalone. However, the lack of proper sealing during packaging results in insufficient storage time after packaging and ineffective drainage of the packaged mushrooms.

[0003] According to publicly available patent CN221586001U, a soft packaging device for king oyster mushrooms includes a box body. The top of the box body has an inlet, and the bottom has an outlet. A pressing mechanism is installed inside the box body, along with a support mechanism for lifting the packaging bag. The pressing mechanism includes a drive component, clamping plates, a hot press plate, and a controller. Two clamping plates are installed inside the box body, and a drive component is provided inside the box body to move the two clamping plates closer together or further apart. A hot press plate is installed on each adjacent side of the two clamping plates. A controller electrically connected to the two hot press plates is located on the top of the box body. In the process of realizing this utility model, [further details are needed]. The present researchers have discovered at least the following unresolved problems in existing technologies: The traditional method involves placing empty flexible packaging bags into the feed inlet, adding king oyster mushrooms inside, activating a drive motor to rotate the output double-threaded rod, and using a controller to adjust the heat on adjacent sides of two heat-sealing plates. The two plates then press against each other to thermo-seal the packaging bag, completing the flexible packaging of the king oyster mushrooms. However, this process requires manual loading of the mushrooms into the bags and then manually removing them to the heat-sealing mechanism for final sealing. This increases labor intensity and results in poor continuity in the flexible packaging process, thus affecting efficiency. Therefore, a new technical solution is needed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a flexible packaging device for king oyster mushrooms. This device solves the technical problems of manually filling king oyster mushrooms into flexible packaging bags and then manually taking the bags to a heat-sealing mechanism for thermoplastic sealing, which increases the labor intensity of personnel and results in poor continuity of flexible packaging, thus affecting the efficiency of flexible packaging of king oyster mushrooms.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a soft packaging device for king oyster mushrooms is designed, including a packaging platform, support plates are installed on both sides of the bottom of the packaging platform, a circular through hole is opened in the middle of the packaging platform, support frames are installed on both sides of the circular through hole, a feeding pipe is installed between the two support frames, mounting frames are installed on both sides of the surface of the packaging platform, plastic film rollers are rotatably installed on both mounting frames, and side sealing mechanisms are provided on both sides of the feeding pipe;

[0006] A bidirectional lead screw and a slide bar are installed between the two support plates. The bidirectional lead screw is rotatably connected between the two support plates. A servo motor is installed on the outer side of one of the support plates. The drive end of the servo motor is connected to the bidirectional lead screw. A sealing and cutting mechanism is provided on the outer side between the bidirectional lead screw and the slide bar.

[0007] Preferably, the side sealing mechanism includes four connecting plates, the length of which is greater than the thickness of the packaging table. The four connecting plates are placed opposite each other on both sides of the feed pipe. Two heat sealing wheels are rotatably connected to the middle of the end of the four connecting plates near the feed pipe. Multiple rubber wheels are rotatably connected to both sides of the heat sealing wheels on the same connecting plate. A driving mechanism is provided at the outer end of each of the four connecting plates.

[0008] Preferably, the sealing and cutting mechanism includes movable plates sleeved on both sides of the bidirectional lead screw and slide bar. Two heat-sealing plates and two cutting blades are provided at the middle of opposite ends of the two movable plates. The two heat-sealing plates and the two cutting blades are distributed alternately in sequence. A first spring is connected between the heat-sealing plates and the movable plates.

[0009] Preferably, the driving mechanism includes a driving motor mounted on the bottom of the connecting plate, a driving sprocket mounted on the driving end of the driving motor, and a plurality of driven sprockets rotatably connected to one end of the connecting plate near the driving sprocket. The plurality of driven sprockets are respectively connected to a rubber wheel and a heat-sealing wheel, and a chain is provided between the driving sprocket and the plurality of driven sprockets.

[0010] Preferably, a telescopic rod is connected between the heat-sealing plate and the movable plate, and the first spring is sleeved on the outside of the telescopic rod.

[0011] Preferably, two adjustment slots are provided on both sides of the surface of the packaging platform, and adjustment blocks are slidably connected in each of the four adjustment slots. The four adjustment blocks are respectively connected to the four connecting plates by mounting rods. A second spring is installed at one end of the inner cavity of each of the four adjustment slots, and the other end of each of the four second springs is respectively connected to the four adjustment blocks.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model combines a side-seam mechanism, a drive mechanism, and a sealing and cutting mechanism to allow for continuous soft packaging of king oyster mushrooms. The mushrooms are simply fed into the plastic film that is heat-sealed together on both sides and the bottom through the feed pipe. This further improves the efficiency of soft packaging of king oyster mushrooms.

[0014] 2. This utility model combines a second spring, an adjusting groove, and an adjusting block. The elastic force of the second spring pushes the adjusting block to move, thereby always pushing the rubber wheels on both sides into contact. This improves the stability of the contact between the rubber wheels and the soft plastic packaging film, and ensures that the rotation of the rubber wheels can drive the soft plastic packaging film to move downwards for soft packaging of the king oyster mushrooms.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0021] Example 1: A flexible packaging device for king oyster mushrooms, see [link to example]. Figures 1 to 4The system includes a packaging platform 1, with support plates 11 installed on both sides of its bottom. A circular through hole 12 is opened in the middle of the packaging platform 1. Support frames 3 are installed on both sides of the circular through hole 12 on the packaging platform 1. A feed pipe 31 is installed between the two support frames 3. Mounting frames 2 are installed on both sides of the surface of the packaging platform 1. Plastic film rollers 21 are rotatably mounted on both mounting frames 2. Side sealing mechanisms are provided on both sides of the feed pipe 31. The side sealing mechanism includes four connecting plates 23. The length of the four connecting plates 23 is greater than the thickness of the packaging platform 1. The four connecting plates 23 are placed in pairs on both sides of the feed pipe 31. Two heat-sealing wheels 26 are rotatably connected to the middle of one end of the connecting plate 23 near the feed pipe 31. Multiple rubber wheels 24 are rotatably connected to both sides of the heat-sealing wheels 26 on the same connecting plate 23. A drive mechanism is provided at one end of the outer side of each of the four connecting plates 23. The drive mechanism includes a drive motor 28 installed at the bottom of the connecting plate 23. A drive sprocket is installed at the drive end of the drive motor 28. Multiple driven sprockets 25 are rotatably connected to one end of the connecting plate 23 near the drive sprocket. The multiple driven sprockets 25 are respectively connected to the rubber wheels 24 and the heat-sealing wheels 26. A chain 27 is provided between the drive sprocket and the multiple driven sprockets 25.A bidirectional lead screw 41 and a slide bar 42 are installed between two support plates 11. The bidirectional lead screw 41 is rotatably connected between the two support plates 11. A servo motor 4 is installed on the outer side of one of the support plates 11. The drive end of the servo motor 4 is connected to the bidirectional lead screw 41. A sealing and cutting mechanism is provided on the outer side between the bidirectional lead screw 41 and the slide bar 42. The sealing and cutting mechanism includes movable plates 43 sleeved on both sides of the bidirectional lead screw 41 and the slide bar 42. Two heat-sealing plates 45 and two cutting blades 44 are provided at the middle of the opposite end of each of the two movable plates 43. The two heat-sealing plates 45 and the two cutting blades 44 are staggered. A first spring 47 is connected between the heat-sealing plates 45 and the movable plates 43. During operation, the soft plastic packaging film on the plastic film rollers 21 on both sides of the feed pipe 31 is placed between the two rubber wheels 24 on the same side and adhered to the outer side of the feed pipe 31. Then, the drive motor 28 is started to drive the drive sprocket 29 to rotate, which, together with the driven sprocket 25 and the chain 27, drives the feed pipe 31 to rotate. The rotating rubber wheel 24 and heat-sealing wheel 26 cause the rubber wheel 24 to bring the two sides of the soft plastic packaging film together and move downwards. Simultaneously, the rotating heat-sealing wheel 26 heat-seals the two sides of the soft plastic packaging film, thus combining the two soft plastic packaging films into a single packaging film with open ends. Then, the servo motor 4 is activated, driving two moving plates 43 to move towards the packaging film. This allows the two heat-sealing plates 45 to heat-seal the top of the packaged king oyster mushroom plastic film and the bottom of the plastic film for the next packaged king oyster mushroom. The moving plates 43 continue to move, coordinating with the first spring 47 to cause the two heat-sealing plates 45 to press against the cutting blade 44, cutting and separating the packaged film from the soft plastic packaging film. Therefore, when soft-packing king oyster mushrooms, the mushrooms only need to be added from the feed pipe 31 into the plastic film that is heat-sealed together on both sides and bottom, allowing for continuous soft-packing of king oyster mushrooms and further improving the efficiency of the packaging process.

[0022] For details, see Figure 4 A telescopic rod 46 is connected between the heat-sealing plate 45 and the moving plate 43, and a first spring 47 is sleeved on the outside of the telescopic rod 46. The telescopic rod 46 can guide the movement of the heat-sealing plate 45, thereby improving the stability of the heat-sealing plate 45 when it compresses and moves under the first spring 47.

[0023] Further, see Figure 2Two adjustment slots 5 are provided on both sides of the surface of the packaging platform 1. Adjustment blocks 51 are slidably connected in each of the four adjustment slots 5. The four adjustment blocks 51 are connected to the four connecting plates 23 by mounting rods 22. A second spring 52 is installed at one end of the inner cavity of each of the four adjustment slots 5. The other end of the four second springs 52 is connected to the four adjustment blocks 51 respectively. The adjustment blocks 51 are pushed to move by the elastic force of the second springs 52, thereby always pushing the rubber wheels 24 on both sides to contact, thereby improving the stability of the contact between the rubber wheels 24 and the soft plastic packaging film, and thus ensuring that the rotation of the rubber wheels 24 can drive the soft plastic packaging film to move downward to softly package the king oyster mushrooms.
