[0002] The packaging device of the red-supported bamboo fungus is designed to effectively protect the bamboo fungus from external damage while maintaining its freshness. The existing packaging method usually puts the bamboo fungus in a plastic box and then wraps the top port of the plastic box with plastic wrap to seal it and keep it fresh.

[0003] Existing packaging devices wrap plastic wrap around the top end of the plastic box to seal and preserve it, but there are some limitations and problems: Problem 1: The existing packaging device uses plastic wrap to preserve the bamboo fungus. A large amount of plastic wrap is needed to seal the bamboo fungus in multiple plastic boxes. When the plastic wrap is wrapped too little, there will be a problem of poor sealing. When the plastic wrap is wrapped too much, there will be a problem of material waste, and the plastic wrap is easily damaged.

[0004] Question 2: After wrapping the plastic box with plastic wrap, air remains between the plastic wrap and the plastic box, which can easily cause oxidation of the bamboo fungus.

DETAILED DESCRIPTION

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] Example: Figures 1-20 As shown, the present invention provides a packaging device for red-supported bamboo fungus, comprising a frame 1, a box 5 and a cover 6. A transmission assembly 4 for pushing the box 5 is mounted on the frame 1, and a guide frame 16 for supporting and sliding the box 5 is mounted on the frame 1. A one-way valve for gas discharge is installed at the bottom of the box 5; Both sides of the frame 1 are fixedly connected with a placement rack 101 for placing the cover 6; The top of the frame 1 is slidably connected to a suction box assembly 7 for feeding the lid 6; An air extraction component 8 is installed on the inner side of the bottom of the frame 1, and the air extraction component 8 cooperates with the one-way valve; Feeding components 2 for feeding bamboo fungus are respectively installed on both sides of the top of the frame 1; The cover 6 is installed at the top of the port of the box 5. A sealing structure is provided between the box 5 and the cover 6. The cover 6 is provided with a contraction groove 603. When the air between the box 5 and the cover 6 is extracted, the contraction groove 603 of the cover 6 is concave. A transparent structure is provided in the middle of the cover 6. The frame 1 is fixedly connected to a support frame 103, on which a limit assembly 9 is installed. After the box 5 and the cover 6 are installed, the limit assembly 9 limits the cover 6 to facilitate the resetting of the box suction assembly 7. The purpose of the above-mentioned arrangement is to push the bamboo fungus through the feeding component 2, push the bamboo fungus into the interior of the box 5, and then push the box 5 through the transmission component 4. The box 5 moves along the guide frame 16 and moves to the bottom of the suction box component 7. The suction box component 7 operates to move the lid 6 on the placement rack 101 for loading, and moves the lid 6 to the top port of the box 5 and puts it down. The lid 6 is installed on the top of the port of the box 5, and the exhaust component 8 cooperates with the one-way valve to extract the internal air of the box 5. When the air between the box 5 and the lid 6 is extracted, the contraction groove 603 of the lid 6 is recessed, so as to facilitate observation of the changes in the internal air of the box 5 when the air is extracted. The extraction of the air inside the box 5 is beneficial to reducing the oxidation of the bamboo fungus. A transparent structure is provided in the middle of the lid 6 for easy observation of the storage condition of the bamboo fungus.

[0044] The upper surface of the box 5 is provided with a sealing groove 501, and both ends of the box 5 are provided with sockets 502, which play a sealing role and are also used for connecting the cover 6; A first motor 401 is mounted on the outer wall of the frame 1. Rotating shafts 405 are rotatably connected to the two ends of the frame 1. One of the rotating shafts 405 is connected to the output shaft of the first motor 401. A plurality of transmission teeth 402 are fixedly connected to the two ends of the rotating shaft 405. A transmission belt 403 is connected between the two rotating shafts 405. The transmission belt 403 is provided with a plurality of tooth grooves, and the transmission teeth 402 mesh with the tooth grooves. A U-shaped frame 404 is connected between the two transmission belts 403. The purpose of the above arrangement is to drive the rotating shaft 405 to rotate through the output shaft of the first motor 401, and the transmission teeth 402 of the rotating shaft 405 drive the transmission belt 403 and the U-shaped frame 404 to operate.

[0045] The sealing structure includes a sealing strip 601, which is fixedly connected to the lower surface of the cover 6 and inserted into the inner side of the sealing groove 501. The two ends of the cover 6 are fixedly connected to rubber collars 602, which connect the cover 6 to the two ends of the box 5 through the rubber collars 602. The transparent structure is made of polycarbonate material. The purpose of the above arrangement is that the sealing strip 601 seals the connection between the lid 6 and the box 5. The lid 6 is connected to both ends of the box 5 through the rubber clamping ring 602. The rubber clamping ring 602 is squeezed through the socket 502 of the box 5, and then the rubber clamping ring 602 is opened to play a limiting role.

[0046] Figure 8 As shown, the feeding assembly 2 includes a discharge plate 201, which is mounted on the top outer wall of the frame 1, and a blowing assembly 3 is mounted between the two discharge plates 201; A first cylinder 202 is mounted on the outer wall of the discharge plate 201, and a push plate 203 is mounted on the output shaft of the first cylinder 202. The push plate 203 is slidably connected to the inner wall of the discharge plate 201, and a sliding groove is provided on the outer wall of the discharge plate 201. The purpose of the above-mentioned setting is that during the operation of the feeding component 2, the blowing component 3 is driven to operate, and the blowing component 3 blows and cleans the dust inside the box 5. The output end of the first cylinder 202 drives the push plate 203 to move, pushing the bamboo fungus placed on the discharge plate 201, and the bamboo fungus falls into the inside of the box 5.

[0047] like Figures 8-10The blowing assembly 3 includes a cylinder 301, which is connected between the two discharge plates 201. A piston 303 is slidably connected to the inner wall of the cylinder 301, and a connecting rod is fixedly connected to the outer wall of the piston 303. The connecting rod passes through the outer wall of the cylinder 301 and extends to the outside. The connecting rod is connected to the push plate 203 through a sliding groove. An exhaust port is provided on the outer wall of the cylinder 301, and the exhaust port faces the box 5. Two diaphragms 302 are connected to the inner wall of the exhaust port, and the two diaphragms 302 are symmetrically attached to each other. The purpose of the above-mentioned arrangement is that during the movement of the push plate 203, the piston 303 is driven to move, and a closed space is formed between the two diaphragms 302 and the piston 303. During the process of the two pistons 303 moving closer to each other, the air inside is pushed out, thereby exhausting the gas. The diaphragm 302 is made of rubber material, and the two fit together. After the exhaust is completed, the two return to fit together. When the two pistons 303 move away from each other, negative pressure will be formed, forcing the two diaphragms 302 to flip inward, thereby drawing the external gas into the interior of the cylinder 301. When the piston 303 stops moving, the diaphragm 302 returns to fit together.

[0048] like Figure 12-14 As shown, the one-way valve includes a valve body 13, which is connected to the bottom of the box 5. A valve core 15 is slidably connected to the inner wall of the valve body 13, and a spring 14 is installed inside the valve body 13; The purpose of the above arrangement is that, during the process of extracting the air inside the box 5 through the vacuum assembly 8, the negative pressure forces the valve core 15 to squeeze the spring 14, and the box 5 is connected to the vacuum assembly 8, so that the air flow inside the box 5 circulates to the outside. After the vacuum is completed, the spring 14 resets the valve core 15 to reduce the flow of external air into the interior of the box 5 again.

[0049] like Figure 1 and Figure 18 A guide rail 102 is provided on the top of the frame 1, and the suction box assembly 7 includes a mobile frame 701, which is slidably connected to the guide rail 102. A second motor 702 is installed on the mobile frame 701, and a roller 703 is installed on the output shaft of the second motor 702. The roller 703 rolls on the guide rail 102; A second cylinder 704 is installed on the mobile frame 701, and a silicone suction cup 705 is installed at the output end of the second cylinder 704; The purpose of the above arrangement is to drive the roller 703 to rotate by the second motor 702, thereby driving the movable frame 701 to slide on the guide rail 102, moving the second cylinder 704 and the silicone suction cup 705 to the top of the cover 6, and the output end of the second cylinder 704 is telescopically controlled to move the silicone suction cup 705 up and down, and the silicone suction cup 705 is adsorbed on the middle position of the cover 6, and then the cover 6 is moved to the top of the box 5, and dropped to dock the cover 6 and the box 5 for installation.

[0050] like Figure 5-Figure 14 As shown, a third motor 11 is mounted on the outer wall of the frame 1, and a rotating shaft 1101 is connected to the output shaft of the third motor 11. The third motor 11 is used to drive the air extraction component 8 to rotate. The air extraction component 8 includes a micro cylinder 801, a mounting seat 802 and a tube body 803. Both ends of the mounting seat 802 pass through the guide frame 16 and the frame 1 and are rotatably connected. The output shaft of the micro cylinder 801 is connected to one end of the mounting seat 802. An arcuate groove 12 is provided on the outer wall of the guide frame 16, and the arcuate groove 12 guides the rotation of the mounting seat 802; The tube body 803 is mounted on the outer wall of the mounting base 802. The outer wall of the mounting base 802 is provided with an air inlet 8030 and an exhaust port 8031. The inner wall of the tube body 803 is slidably connected to the plug body 804. The output shaft of the micro cylinder 801 passes through the mounting base 802 and is connected to the plug body 804. The purpose of the above-mentioned arrangement is that the output shaft of the third motor 11 drives the rotating shaft 1101 to rotate, and drives the vacuum assembly 8 to move from the top position of the arc groove 12 to the bottom position, thereby avoiding obstruction to the movement of the box 5. When it is necessary to extract the gas inside the box 5, the valve body 13 of the box 5 is docked with the air inlet 8030 of the tube body 803, and the output end of the micro cylinder 801 drives the plug body 804 to move. Under the action of negative pressure, the air inside the box 5 is extracted. When the plug body 804 passes through the exhaust port 8031, the pressure is released. After the vacuum is completed, the spring 14 resets the valve core 15 to reduce the flow of external air into the interior of the box 5 again.

[0051] like Figure 17 As shown, the limiting assembly 9 includes a driving motor 901, which is mounted on a support frame 103. A driving gear 902 is mounted on the output shaft of the support frame 103. The top of the support frame 103 is rotatably connected to a driven gear 903, and the driven gear 903 and the driving gear 902 are meshed with each other. A screw rod 905 is fixedly connected to the outer wall of the driven gear 903, and a limit frame 904 is threadedly connected to the outer wall of the screw rod 905. A guide groove 1030 is provided on the top of the support frame 103, and one end of the limit frame 904 is slidably connected to the guide groove 1030; The purpose of the above arrangement is that the driving motor 901 drives the driving gear 902 to rotate, the driving gear 902 drives the driven gear 903 and the screw 905 to rotate, the screw 905 drives the limit frame 904, and the limit frame 904 moves to the top of the cover 6. After the box 5 and the cover 6 are installed, when the silicone suction cup 705 rises, the limit frame 904 blocks and limits the top of the cover 6 to prevent the silicone suction cup 705 from sucking up the box 5 and the cover 6 when it rises.

[0052] The material receiving rack 10 is fixedly connected to one end of the frame 1, and an inclined surface 1001 is provided on the material receiving rack 10; The purpose of the above arrangement is that after the box 5 and the lid 6 are installed, they are transported to the material receiving rack 10 by the transmission assembly 4 for discharge. The formed packaging box first moves along the slope of the material receiving rack 10. As the unloading width of the material receiving rack 10 becomes larger and larger, the packaging box slides to the bottom of the material receiving rack 10.

[0053] Working principle: the box 5 is placed on the guide frame, and the output end of the first cylinder 202 drives the push plate 203 to move. During the movement of the push plate 203, the piston 303 is driven to move, and a closed space is formed between the two diaphragms 302 and the piston 303. During the movement of the two pistons 303 approaching each other, the air inside is pushed out, thereby exhausting. The diaphragm 302 is made of rubber material, and the two fit each other. After the exhaust is completed, the two return to fit. When the two pistons 303 move away from each other, negative pressure is formed, forcing the two diaphragms 302 to flip inward, thereby drawing external gas into the interior of the cylinder 301. When the piston 303 stops moving, the diaphragm 302 returns to fit. During the flow of air, the dust inside the box 5 is blown away, and the push plate 203 moves to push the bamboo fungus placed on the discharge plate 201, and the bamboo fungus falls into the interior of the box 5. The output shaft of the first motor 401 drives the rotating shaft 405 to rotate, and the transmission gear 402 of the rotating shaft 405 drives the transmission belt 403 and the U-shaped frame 404 to operate. The U-shaped frame 404 slowly pushes the box 5 to the bottom of the suction box assembly 7, and at the same time, the one-way valve of the box 5 is connected and docked with the air extraction assembly 8; The second motor 702 drives the roller 703 to rotate, thereby driving the movable frame 701 to slide on the guide rail 102, moving the second cylinder 704 and the silicone suction cup 705 to above the cover 6. The output end of the second cylinder 704 is extended and retracted to control the silicone suction cup 705 to move up and down, and the silicone suction cup 705 is adsorbed on the middle position of the cover 6. Then, the cover 6 is moved above the top of the box 5 and dropped to dock the cover 6 with the box 5 for installation. The driving motor 901 drives the driving gear 902 to rotate, and the driving gear 902 drives the driven gear 903 and the screw 905 to rotate. The screw 905 drives the limiting frame 904, and the limiting frame 904 moves to the top of the cover 6. After the box 5 and the cover 6 are installed, when the silicone suction cup 705 rises, the limiting frame 904 blocks the top of the cover 6 to prevent the silicone suction cup 705 from sucking up the box 5 and the cover 6 when it rises; To evacuate the air inside the box 5, the valve body 13 of the box 5 is docked with the air inlet 8030 of the tube 803. The output end of the micro-cylinder 801 drives the plug 804 to move. Under the action of negative pressure, the air inside the box 5 is evacuated. When the plug 804 passes the exhaust port 8031, the pressure is released. After the air extraction is completed, the spring 14 resets the valve core 15 to prevent the external air from flowing into the box 5 again. When the air between the box 5 and the lid 6 is reduced, the shrinkage groove 603 of the lid 6 is recessed, so that it is easy to observe the changes when the air inside the box 5 is extracted. At the same time, the sealing strip 601 of the lid 6 is more tightly engaged with the sealing groove of the box 5. Compared with the existing technology, the sealing performance is better. The reduction of air is conducive to reducing the oxidation of the bamboo fungus, effectively inhibiting the circulation of moisture and air, reducing the probability of mold growth, and keeping the bamboo fungus dry and hygienic. After the box 5 and the lid 6 are installed, they are transported by the transmission assembly 4 to the receiving rack 10 for discharge. The formed packaging boxes first move along the slope of the receiving rack 10. As the unloading width of the receiving rack 10 becomes larger and larger, the packaging boxes slide to the bottom of the receiving rack 10 for collection. The box 5 and the lid 6 are made of the plastic material of the existing packaging box. The specific material can be selected by technicians in this field according to the use requirements. When the box 5 and the cover 6 need to be disassembled, Figure 12-14 As shown, a slender rod is fixedly connected to the outer wall of the valve core 15 and extends to the outside of the port of the valve body 13. Pulling the slender rod drives the valve core 15 to move to release pressure, allowing air to enter the interior of the box 5, so that the box 5 and the lid 6 can be disassembled, and the rubber clamping ring 602 is squeezed to lift the lid 6 and pick it up from the port of the box 5, so that the bamboo fungus can be taken out.
