Description

Technical Field

[0001] The present invention relates to the technical field of food processing, and particularly to an irradiation preservation device for food processing. Background Art

[0002] In food processing and preservation, processing measures are taken to prevent food from spoiling, extend its shelf life, and enable long-term storage of food. Common methods include low-temperature preservation, high-temperature preservation, dehydration preservation, increasing the osmotic pressure of food, increasing the hydrogen ion concentration of food, irradiation preservation, air isolation, adding preservatives and antioxidants, etc.

[0003] Among them, irradiation preservation is a food processing method that uses the energy of electromagnetic wave radiation to damage the DNA structure in organisms, making it impossible for microorganisms to continue to reproduce, and at the same time can also cause the plant germ to stop growing and differentiating. At present, when irradiating and processing food, a storage frame is mainly used in combination with a conveying mechanism to convey the food to the irradiation area for irradiation treatment, and the processed food is sent out by the conveying mechanism. Specifically, reference can be made to the patent document with the patent application number CN201820274621.2 of our company, whose patent title is a food irradiation system, including an irradiation chamber, a shipping area and a waiting transportation area. There is a circular upper track above them, and a spreader track is located below the side of the circular upper track. A number of spreaders are hung on the spreader track. There is a hook on the circular upper track. The rear end of the hook slopes downward and can only be lifted upward. The front end of the hook is provided with an inclined plate that slopes backward. The slope of the inclined plate is greater than that of the hook. The lower end of the inclined plate is higher than the lower end of the hook; below the upper track is the spreader track. A decoupling flat plate is provided between the upper track and the spreader track. The upper surface of the decoupling flat plate is lower than the upper end of the inclined plate, and the lower surface of the decoupling flat plate is higher than the lower end of the inclined plate. When the lower end of the inclined plate is located on the decoupling flat plate, the lower end of the hook is higher than the lower end of the inclined plate, which can mainly achieve automatic decoupling, and shipping, transportation and irradiation can be carried out simultaneously, with high work efficiency.

[0004] However, for the existing irradiation system, in the actual irradiation processing process, especially in the process of transferring food to the storage frame, traditionally, it is necessary to manually stack the packaged food in the storage frame from bottom to top in turn. During the whole process, it is necessary to continuously lift the packaged food, and as the number of stacked food increases, the lifting height also continuously rises, and the manual burden also becomes greater and greater, resulting in a large continuous labor intensity of manual work, easy fatigue, and corresponding increase in work safety hazards after fatigue. Therefore, we propose an irradiation preservation device for food processing. Summary of the Invention

[0005] The purpose of the present invention is to provide an irradiation preservation device for food processing to solve the problems raised in the above background art.

[0006] To achieve the above object, the present invention provides the following technical solution: An irradiation preservation device for food processing, comprising a storage rack for carrying items for conveying and irradiating. The storage rack includes a main frame with an opening on one side and a side door hinged at the opening position of the main frame. A plurality of horizontal storage plates are sequentially arranged from bottom to top on the inner side of the side door. After the side door is opened, food is placed between adjacent horizontal storage plates, and when the side door is closed, the food is directly stacked from top to bottom in the main frame;

[0007] And a horizontal outlet is opened at the top of the inner side of the side door, and a movable top plate mechanism is arranged in the horizontal outlet. When the side door is closed, the food on the movable top plate mechanism drives the movable top plate mechanism to slide in the horizontal outlet. After the side door is closed, the movable top plate mechanism is pushed to push the top layer of food into the main frame for stacking;

[0008] And a limiting member for restricting the deflection of the side door is arranged between the side door and the main frame, which restricts the deflection of the side door and prevents it from opening by itself after the side door is closed.

[0009] The movable top plate mechanism includes an L-shaped moving plate slidably arranged in the horizontal outlet. A limiting chute with anti-disengagement ability is opened at the bottom edge position of the horizontal outlet. A guide rail slider slidably arranged in the limiting chute is installed at the bottom of the L-shaped moving plate, so that the L-shaped moving plate can move arbitrarily in the horizontal outlet;

[0010] It also includes a positioning member arranged in the limiting chute, which is used to limit the movement of the L-shaped moving plate when the L-shaped moving plate and the guide rail slider are horizontal, and when the L-shaped moving plate and the guide rail slider are vertical, the L-shaped moving plate can move arbitrarily in the limiting chute.

[0011] The positioning member includes a block slidably arranged in the limiting chute. The top end of the block is a wedge-shaped hypotenuse structure, and a slot is opened at the bottom of the guide rail slider, and the side of the slot is in contact with the top hypotenuse of the block;

[0012] It also includes a guiding member arranged in the limiting chute. The guiding member restricts the directional lifting of the block in the limiting chute, and an elastic member is also arranged between the block and the inner wall of the limiting chute. When the L-shaped moving plate is vertically loaded, the side of the slot on the guide rail slider pushes the wedge-shaped block to move, so as to push the block out of the slot to meet the arbitrary movement of the guide rail slider, and when the L-shaped moving plate is horizontal, the block is inserted into the slot to position the guide rail slider and the L-shaped moving plate.

[0013] The guiding member includes reels arranged on both sides in the limiting chute. The block is located between the two reels on both sides and is in rolling connection with both reels at the same time.

[0014] The elastic member includes a magnet 1 embedded at one end of the block away from the guide rail slider, and a magnet 2 is embedded on the side of the limiting chute opposite to the magnet 1, and the opposite surfaces of the magnet 1 and the magnet 2 have the same magnetic poles.

[0015] The limiting component includes a first magnetic strip embedded in the side door, and a second magnetic strip embedded on one side of the opening of the main body frame. The opposite faces of the first magnetic strip and the second magnetic strip have opposite magnetic poles.

[0016] A first bearing seat is arranged at the top of the main body frame. A first rotating shaft is arranged on the first bearing seat. A traction rope is fixedly wound around the first rotating shaft. The free end of the traction rope is connected to the top of the side door.

[0017] It further includes a first torsion spring arranged outside the first rotating shaft. The two ends of the first torsion spring are respectively fixed to the first bearing seat and the first rotating shaft. When the side door is opened, the first rotating shaft is rotated by pulling the traction rope, and the first torsion spring is forced to contract.

[0018] An active hook-and-loop mechanism is arranged at the top of the main body frame. The active hook-and-loop mechanism cooperates with the side door. When the side door is opened to load food, the active hook-and-loop mechanism is misaligned and will not be hooked and conveyed by the conveying mechanism. After the side door is loaded with food and closed, the active hook-and-loop mechanism is in the correct position and waits to be hooked and conveyed by the conveying mechanism.

[0019] And a support component capable of reducing the lateral friction of the main body frame is arranged at the bottom of the main body frame, so as to prevent the main body frame from tilting when the conveying mechanism hooks the active hook-and-loop mechanism to drive the main body frame to move.

[0020] The active hook-and-loop mechanism includes a second bearing seat arranged at the top of the main body frame. A second rotating shaft is arranged on the second bearing seat. A collar is arranged on the second rotating shaft, and the position state of the collar is changed by the second rotating shaft.

[0021] It further includes an L-shaped buckle plate arranged at the top of the main body frame. A through groove is formed in the L-shaped buckle plate. A buckle seat is arranged at the top of the main body frame. The L-shaped buckle plate slides through the buckle seat to limit the directional sliding of the L-shaped buckle plate on the top of the main body frame.

[0022] It further includes a sliding rod installed in the through groove. The sliding rod slidably penetrates through the buckle seat, and a spring is sleeved outside the sliding rod. The two ends of the spring are respectively abutted against the buckle seat and the inner wall of the through groove.

[0023] And continuous tooth grooves are formed in the L-shaped buckle plate. The bottom of the collar is of an arc-shaped structure, and continuous teeth engaging with the tooth grooves are arranged at the bottom thereof. In the closed state of the side door, the spring is in a stretched state, and the collar is in the correct position to be hooked.

[0024] The support component includes self-locking universal wheels respectively arranged at the four corner positions of the bottom of the main body frame.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. Through the structural design of the storage shelves of the main frame and the side door, and in combination with the use of the movable top plate mechanism and the limiting components, when stacking the packaged foods inside the storage shelves, it is only necessary to place the foods on the corresponding storage horizontal plates and the movable top plate in sequence, then close the side door, and use the movable top plate mechanism to place the top-layer foods at the inner top of the storage shelves, thus completing the stacking of the irradiated foods in the storage shelves. The whole process does not require manual continuous lifting of the foods, effectively reducing the manual labor intensity and effectively improving the safety of the manual continuous labor.

[0027] 2. By using the designed movable hook ring mechanism and the supporting components, the present invention can correspondingly change the to-be-hooked state of the storage shelves at the conveying mechanism according to the opening and closing states of the side door, that is, to ensure the absolute separation of the storage shelves from the conveying mechanism when shipping the irradiated products, and at the moment of closing the side door after the shipping is completed, switch the storage shelves to the hooked and conveyed state, thereby effectively avoiding the situation of stopping the machine to ship the goods;

[0028] In addition, the setting of the supporting components can also effectively avoid the lateral friction of the storage shelves when they are hooked and moved, thus effectively avoiding the situation that the storage shelves tilt and shake due to friction, and ensuring the stable conveyance for irradiation use.

Specific embodiments

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] Embodiment 1

[0044] Please refer to Figure 1-10 , the present invention provides a technical solution: an irradiation preservation device for food processing, including a storage rack 1 for carrying items for conveying and irradiating. The storage rack 1 includes a main body frame 11 with an opening on one side and a side door 12 hinged at the opening position of the main body frame 11. A plurality of horizontal storage boards 13 are sequentially arranged from bottom to top on the inner side of the side door 12. After the side door 12 is opened, food is placed between adjacent horizontal storage boards 13, and when the side door 12 is closed, the food is directly stacked from top to bottom in the main body frame 11;

[0045] And a horizontal outlet 14 is provided at the inner top of the side door 12. An active top plate mechanism 2 is arranged in the horizontal outlet 14. When the side door 12 is closed, the food on the active top plate mechanism 2 drives the active top plate mechanism 2 to slide in the horizontal outlet 14. After the side door 12 is closed, the active top plate mechanism 2 is pushed to push the top-layer food into the main body frame 11 for stacking.

[0046] And a limiting member 3 for restricting the deflection of the side door 12 is arranged between the side door 12 and the main body frame 11, which restricts the deflection of the side door 12 after it is closed and prevents it from opening by itself.

[0047] With the above design, when loading goods into the storage rack 1, the side door 12 is opened. Only need to place the food on the corresponding storage horizontal plate 13 and the active top plate mechanism 2 in sequence, and then close the side door 12. During the closing process, the active top plate mechanism 2 is used to place the top-layer food on the top of the storage rack 1, and the stacking of irradiated food in the storage rack 1 can be completed. The whole process does not require manual continuous lifting of food, effectively reducing the manual labor intensity and effectively improving the safety of manual continuous labor.

[0048] As an embodiment, the active top plate mechanism 2 includes an L-shaped moving plate 21 slidably arranged in the horizontal outlet 14. A limiting chute 22 with anti-detachment ability is provided at the bottom edge position of the horizontal outlet 14. A guide rail slider 23 slidably arranged in the limiting chute 22 is installed at the bottom of the L-shaped moving plate 21, so that the L-shaped moving plate 21 can move arbitrarily in the horizontal outlet 14. With such a design, when loading goods, for the bottom-layer goods in the storage rack 1, they can be directly placed on the storage horizontal plate 13, as shown in the attachment Figure 3 shown. For the top-layer goods in the storage rack 1, they are correspondingly placed on the L-shaped moving plate 21. And with its L-shaped structure design, the goods are stably placed on the L-shaped moving plate 21. When the side door 12 is flipped, the top-layer goods press the L-shaped moving plate 21 to move, as shown in the attachment Figure 4 shown. In this way, it can effectively prevent the top-layer goods from being blocked by the top opening of the main body frame 11 when the side door 12 is closed. Then, the L-shaped moving plate 21 together with the goods is pushed into the main body frame 11 by hand, as shown in the attachment Figure 5 shown, and they can be stably stacked, effectively avoiding the continuous lifting and handling of goods during the loading of the main body frame 11.

[0049] It also includes a positioning member 24 arranged in the limiting chute 22. When the L-shaped moving plate 21 and the guide rail slider 23 are horizontal, the movement of the L-shaped moving plate 21 is restricted by the positioning member 24. And when the L-shaped moving plate 21 and the guide rail slider 23 are vertical, the L-shaped moving plate 21 can move arbitrarily in the limiting chute 22. At this time, with the design of the positioning member 24, the position of the L-shaped moving plate 21 is effectively restricted to ensure its stability after being pushed into the main body frame 11, so as to be stably pushed for use.

[0050] Similarly, as an embodiment, the positioning member 24 includes a clamping block 241 slidably arranged in the limiting chute 22. The top end of the clamping block 241 is a wedge-shaped hypotenuse structure, and a slot 242 is formed at the bottom of the guide rail slider 23. The side of the slot 242 is in contact with the top hypotenuse of the clamping block 241;

[0051] It further includes a guiding member 25 arranged in the limiting chute 22. The guiding member 25 includes winding shafts 251 arranged on both sides in the limiting chute 22. The clamping block 241 is located between the winding shafts 251 on both sides and is simultaneously in rolling connection with the winding shafts 251 on both sides to limit the directional lifting of the clamping block 241 in the limiting chute 22 and effectively reduce the contact friction during the longitudinal lifting of the clamping block 241, thereby facilitating the guide rail slider 23 to push the hypotenuse clamping block 241 to move;

[0052] An elastic member 26 is further arranged between the clamping block 241 and the inner wall of the limiting chute 22. The elastic member 26 includes a magnet 261 embedded at one end of the clamping block 241 away from the guide rail slider 23, and a magnet 262 is embedded on the side of the limiting chute 22 opposite to the magnet 261. The opposite surfaces of the magnet 261 and the magnet 262 have the same magnetic poles. When the L-shaped moving plate 21 bears weight vertically, the side of the slot 242 on the guide rail slider 23 pushes the wedge-shaped clamping block 241 to move, so as to push the clamping block 241 out of the slot 242 to meet the arbitrary movement of the guide rail slider 23. At this time, the clamping block 241 is forced to press down against the repulsive force between the magnet 261 and the magnet 262. When the L-shaped moving plate 21 is placed horizontally and pushed into the main body frame 11, the clamping block 241 is inserted into the slot 242 to position the guide rail slider 23 and the L-shaped moving plate 21. The magnetic repulsive force between the magnet 261 and the magnet 262 is used to push the clamping block 241 to reset and insert into the slot 242 to position the L-shaped moving plate 21, ensuring its stable object placement and movement. The setting that uses its magnetic repulsive force to provide the clamping block 241 with the ability of self-resetting movement is ingenious, with a simple structure and low cost.

[0053] Similarly, as an embodiment, the limiting component 3 includes a magnetic strip 35 embedded in the side door 12, and a magnetic strip 36 is embedded on one side of the opening of the main body frame 11. The opposite surfaces of the magnetic strip 35 and the magnetic strip 36 have opposite magnetic poles. In this way, after the side door 12 is closed, the adsorption force between the magnetic strip 35 and the magnetic strip 36 can be used to effectively position the side door 12, ensuring the stable conveying and movement of the products to be irradiated inside.

[0054] Furthermore, a bearing seat 31 is arranged on the top of the main body frame 11. A rotating shaft 32 is arranged on the bearing seat 31, and a traction rope 33 is fixedly wound around the rotating shaft 32. The free end of the traction rope 33 is connected to the top of the side door 12;

[0055] It also includes a first torsion spring 34 arranged outside the first rotating shaft 32. The two ends of the first torsion spring 34 are respectively fixed to the first bearing seat 31 and the first rotating shaft 32. When the side door 12 is opened, the first rotating shaft 32 is driven to rotate by the towing rope 33, and the first torsion spring 34 is forced to contract. With such a design, after the side door 12 is opened, it is necessary to overcome the elastic pulling force of the first torsion spring 34 during winding at this time to forcibly keep the side door 12 in the open state. However, when the side door 12 is closed, the traction force of the first torsion spring 34 and the towing rope 33 can be used to tow the side door 12 to close, so as to achieve the purpose of saving effort, and thus effectively facilitate the labor-saving closing use of the side door 12 filled with products.

[0056] Furthermore, a movable hook and loop mechanism 4 is arranged at the top of the main body frame 11. The movable hook and loop mechanism 4 cooperates with the side door 12. When the side door 12 is opened to load food, the movable hook and loop mechanism 4 is misaligned and will not be hooked and conveyed by the conveying mechanism. For the conveying mechanism, because it can realize the automatic unhooking and automatic hooking and conveying of the main body frame 11, although it can automatically hook and convey the storage rack 1, when loading goods in the storage rack 1, the entire device can only be stopped and continue to move after loading the goods. Otherwise, when loading goods, the storage rack 1 will be directly hooked and conveyed away by the conveying mechanism, or the hook and loop of the storage rack 1 is set to be adjustable and switchable. After loading the goods, manually or using an electric device to automatically control the state of the hook and loop to switch it to the state to be hooked. However, the overall height of the storage rack 1 is relatively high, manual operation is not safe, and it increases the workload of workers, which is very inconvenient. When using an electric control device to control, the simplest is an electric push rod or a cylinder, but a control unit (remote control or control button) needs to be added, and the problem of continuous power supply needs to be considered. A mobile power supply needs to be added to the storage rack 1, which not only increases the overall weight and the burden on the conveying mechanism, but also seriously increases the use cost. In this case, with the designed movable hook and loop mechanism 4, the hooking state of the storage rack 1 can be switched instantly when the side door 12 is closed, so that the device can meet the goods loading of the storage rack 1 without stopping, so as to conveniently meet the continuous conveying and irradiation use.

[0057] And a support member 5 capable of reducing the lateral friction of the main body frame 11 is arranged at the bottom of the main body frame 11 to prevent the main body frame 11 from tilting when the conveying mechanism hooks the movable hook and loop mechanism 4 to drive the main body frame 11 to move.

[0058] As an embodiment, the movable hook and loop mechanism 4 includes a second bearing seat 41 arranged at the top of the main body frame 11. A second rotating shaft 42 is arranged on the second bearing seat 41, and a collar 43 is arranged on the second rotating shaft 42. The position state of the collar 43 is changed by the second rotating shaft 42.

[0059] It further includes an L-shaped clamping plate 44 arranged at the top of the main body frame 11. A through groove 45 is formed in the L-shaped clamping plate 44, and a clamping seat 46 is arranged at the top of the main body frame 11. The L-shaped clamping plate 44 slides through the clamping seat 46 to limit the directional sliding of the L-shaped clamping plate 44 at the top of the main body frame 11;

[0060] It further includes a sliding rod 47 installed in the through groove 45. The sliding rod 47 slides through the clamping seat 46, and a spring 48 is sleeved outside the sliding rod 47. Two ends of the spring 48 are respectively abutted against the clamping seat 46 and the inner wall of the through groove 45;

[0061] And continuous tooth grooves 49 are formed in the L-shaped clamping plate 44. The bottom of the collar 43 is an arc-shaped structure, and continuous teeth 410 that engage with the tooth grooves 49 are arranged at the bottom thereof. In the closed state of the side door 12, the spring 48 is in a stretched state, and the collar 43 is in a normal position waiting to be hooked. At the moment when the side door 12 is closed, the deflection state of the collar 43 is switched, and then it is switched to a hooked state to meet the shipment of goods without stopping the machine.

[0062] As an embodiment, the supporting member 5 includes self-locking universal wheels 51 respectively arranged at the four corner positions of the bottom of the main body frame 11. In this way, when the conveying mechanism hooks the storage rack 1 and moves it horizontally for conveying, the self-locking universal wheels 51 roll to reduce the horizontal friction, so as to stably move it horizontally for conveying and avoid tilting due to the influence of friction force.

[0063] Embodiment 2

[0064] Please refer to Figure 11-12 , the present invention provides another technical solution: an irradiation preservation device for food processing, including a storage rack 1 for carrying items for conveying and irradiating. The storage rack 1 includes a main body frame 11 with an opening on one side and a side door 12 hinged at the opening position of the main body frame 11. A plurality of storage cross plates 13 are sequentially arranged from bottom to top on the inner side of the side door 12. After the side door 12 is opened, food is placed between adjacent storage cross plates 13, and when the side door 12 is closed, the food is directly stacked from top to bottom in the main body frame 11;

[0065] And a horizontal outlet 14 is formed at the top inner side of the side door 12, and a movable top plate mechanism 2 is arranged in the horizontal outlet 14. When the side door 12 is closed, the food on the movable top plate mechanism 2 drives the movable top plate mechanism 2 to slide in the horizontal outlet 14. After the side door 12 is closed, the movable top plate mechanism 2 is pushed to push the top layer of food into the main body frame 11 for stacking;

[0066] And a limiting member 3 for limiting the deflection of the side door 12 is arranged between the side door 12 and the main body frame 11 to limit the deflection of the side door 12 after it is closed and prevent it from opening by itself.

[0067] With the above design, when loading goods into the storage rack 1, open the side door 12. Just place the food items on the corresponding horizontal storage plates 13 and the movable top plate mechanism 2 in sequence, then close the side door 12, and use the movable top plate mechanism 2 to place the top-layer food items on the top of the storage rack 1. Thus, the stacking of irradiated food items in the storage rack 1 can be completed. Throughout the process, there is no need for manual continuous lifting of the food items, effectively reducing the manual labor intensity and significantly enhancing the safety of continuous manual labor.

[0068] As an embodiment, the movable top plate mechanism 2 includes an L-shaped moving plate 21 slidably disposed in the horizontal outlet 14. A limiting chute 22 with anti-disengagement ability is provided at the bottom edge of the horizontal outlet 14. A guide rail slider 23 slidably disposed in the limiting chute 22 is installed at the bottom of the L-shaped moving plate 21, enabling the L-shaped moving plate 21 to move freely within the horizontal outlet 14. With such a design, when loading goods, for the bottom-layer goods in the storage rack 1, they can be directly placed on the horizontal storage plates 13, while for the top-layer goods in the storage rack 1, they are correspondingly placed on the L-shaped moving plate 21. And with its L-shaped structure design, the goods are stably placed on the L-shaped moving plate 21. When the side door 12 is flipped, the top-layer goods press the L-shaped moving plate 21 to move, effectively preventing the top-layer goods from being blocked by the top opening of the main frame 11 when the side door 12 is closed. Then, push the L-shaped moving plate 21 together with the goods into the main frame 11 by hand, and they can be stably stacked, effectively avoiding the continuous lifting and carrying of goods during the loading of the main frame 11.

[0069] It further includes a positioning member 24 disposed in the limiting chute 22. When the L-shaped moving plate 21 and the guide rail slider 23 are horizontal, the positioning member 24 is used to limit the movement of the L-shaped moving plate 21. And when the L-shaped moving plate 21 and the guide rail slider 23 are vertical, the L-shaped moving plate 21 can move freely within the limiting chute 22. At this time, with the design of the positioning member 24, the position of the L-shaped moving plate 21 is effectively limited to ensure its stability after being pushed into the main frame 11, thus enabling stable pushing for use.

[0070] Similarly, as an embodiment, the positioning member 24 includes a block 241 slidably disposed in the limiting chute 22. The top of the block 241 is a wedge-shaped hypotenuse structure, and a slot 242 is provided at the bottom of the guide rail slider 23. The side of the slot 242 contacts the top hypotenuse of the block 241.

[0071] It further includes a guiding member 25 disposed in the limiting chute 22. The guiding member 25 includes winding shafts 251 provided on both sides within the limiting chute 22. The block 241 is located between the winding shafts 251 on both sides and is simultaneously in rolling connection with the winding shafts 251 on both sides to limit the directional lifting of the block 241 within the limiting chute 22 and effectively reduce the contact friction during the longitudinal lifting of the block 241, thus facilitating the top movement of the guide rail slider 23 to move the hypotenuse block 241.

[0072] An elastic member 26 is further provided between the clamping block 241 and the inner wall of the limit sliding groove 22. The elastic member 26 includes a first magnet 261 embedded at one end of the clamping block 241 away from the guide rail slider 23, and a second magnet 262 is embedded on the side edge of the limit sliding groove 22 opposite to the first magnet 261. The opposite surfaces of the first magnet 261 and the second magnet 262 have the same magnetic poles. When the vertical load-bearing part of the L-shaped moving plate 21 is in place, the side of the slot 242 on the guide rail slider 23 pushes the wedge-shaped clamping block 241 to move, so as to push the clamping block 241 out of the slot 242 to meet the arbitrary movement of the guide rail slider 23. At this time, the clamping block 241 is forced to press down against the repulsive force between the first magnet 261 and the second magnet 262. When the L-shaped moving plate 21 is placed horizontally and pushed into the main body frame 11, the clamping block 241 is inserted into the slot 242 to position the guide rail slider 23 and the L-shaped moving plate 21. The magnetic repulsive force between the first magnet 261 and the second magnet 262 is used to push the clamping block 241 to reset and insert into the slot 242 to position the L-shaped moving plate 21, ensuring its stable placement and movement. The setting that uses its magnetic repulsive force to provide the clamping block 241 with the ability of self-resetting movement is ingenious, with simple structure and low cost.

[0073] Similarly, as an embodiment, the limiting member 3 includes a first magnetic strip 35 embedded on the side door 12, and a second magnetic strip 36 is embedded on one side of the opening of the main body frame 11. The opposite surfaces of the first magnetic strip 35 and the second magnetic strip 36 have opposite magnetic poles. In this way, after the side door 12 is closed, the adsorption force between the first magnetic strip 35 and the second magnetic strip 36 can be used to effectively position the side door 12, ensuring the stable conveying and movement of the products to be irradiated inside.

[0074] Furthermore, a first bearing seat 31 is provided on the top of the main body frame 11, a first rotating shaft 32 is provided on the first bearing seat 31, a traction rope 33 is fixedly wound around the first rotating shaft 32, and the free end of the traction rope 33 is connected to the top of the side door 12;

[0075] A first torsion spring 34 is further provided outside the first rotating shaft 32. The two ends of the first torsion spring 34 are respectively fixed to the first bearing seat 31 and the first rotating shaft 32. When the side door 12 is opened, the traction rope 33 is used to pull the first rotating shaft 32 to rotate, and the first torsion spring 34 is forced to contract. With such a design, after the side door 12 is opened, it is necessary to overcome the elastic force of the first torsion spring 34 during winding at this time to forcibly keep the side door 12 in the open state. However, when the side door 12 is closed, the traction force of the first torsion spring 34 and the traction rope 33 can be used to pull the side door 12 to close, so as to achieve the purpose of saving effort, and further effectively facilitate the labor-saving closing of the side door 12 filled with products.

[0076] Furthermore, an active hook mechanism 4 is provided at the top of the main body frame 11. The active hook mechanism 4 cooperates with the side door 12. When the side door 12 is opened to load food, the active hook mechanism 4 is misaligned and will not be hooked and conveyed by the conveying mechanism. For the conveying mechanism, precisely because it can achieve automatic unhooking and automatic hooking and conveying of the main body frame 11, although it can automatically hook and convey the storage rack 1, when loading goods in the storage rack 1, the entire device can only be stopped and then continue to move after the goods are loaded. Otherwise, when loading goods, the storage rack 1 will be directly hooked and conveyed away by the conveying mechanism, or the hook of the storage rack 1 is set to be adjustable and switchable. After loading the goods, manually or using an electric device to automatically control the state of the hook to switch it to the state to be hooked. However, the overall storage rack 1 is relatively high, manual operation is not safe, and it increases the workload of workers, which is very inconvenient. When using an electric control device to control, the simplest ones are electric push rods or cylinders, but a control unit (remote control or control button) needs to be added, and the problem of continuous power supply needs to be considered. A mobile power supply needs to be added to the storage rack 1, which not only increases the overall weight and burdens the conveying mechanism, but also seriously increases the use cost. In this case, by using the designed active hook mechanism 4, the hooking state of the storage rack 1 can be switched instantly when the side door 12 is closed, so that the device can meet the goods loading of the storage rack 1 without stopping, so as to conveniently meet the continuous conveying and irradiation use.

[0077] And a support member 5 capable of reducing the lateral friction of the main body frame 11 is provided at the bottom of the main body frame 11 to prevent the main body frame 11 from tilting when the conveying mechanism hooks the active hook mechanism 4 to drive the main body frame 11 to move.

[0078] As an embodiment, the active hook mechanism 4 includes a second bearing seat 41 provided at the top of the main body frame 11. A second rotating shaft 42 is provided on the second bearing seat 41, and a collar 43 is provided on the second rotating shaft 42. The position state of the collar 43 is changed by using the second rotating shaft 42;

[0079] It further includes an L-shaped clamping plate 44 provided at the top of the main body frame 11. A through groove 45 is opened on the L-shaped clamping plate 44. A clamping seat 46 is provided at the top of the main body frame 11. The L-shaped clamping plate 44 slides through the clamping seat 46 to limit the directional sliding of the L-shaped clamping plate 44 on the top of the main body frame 11;

[0080] It further includes a sliding rod 47 installed in the through groove 45. The sliding rod 47 slides through the clamping seat 46, and a spring 48 is sleeved outside the sliding rod 47. Both ends of the spring 48 are abutted against the clamping seat 46 and the inner wall of the through groove 45 respectively;

[0081] And a continuous tooth groove 49 is formed in the L-shaped buckle plate 44. The bottom of the collar 43 is of an arc-shaped structure, and continuous teeth 410 that engage with the tooth groove 49 are provided at the bottom thereof. When the side door 12 is in the closed state, the spring 48 is in a stretched state, and the collar 43 is in a proper position to be hooked. At the moment when the side door 12 is closed, the deflection state of the collar 43 is switched, and then it is switched to a hooked state to meet the shipment of goods under the non-stop state.

[0082] As an embodiment, the support member 5 includes bearing seats three 52 arranged on both sides of the bottom of the main body frame 11. A bearing shaft 53 is arranged on the bearing seat three 52. A deflection support leg 54 is arranged on the bearing shaft 53, and a second coil spring 55 with two ends respectively connected to the bearing seat three 52 and the deflection support leg 54 is arranged on the bearing shaft 53.

[0083] And an L-shaped top plate 56 is arranged at the bottom of the side door 12. When the side door 12 is opened, the L-shaped top plate 56 is inserted into the two deflection support legs 54 to limit the simultaneous deflection of the deflection support legs 54, so as to stably support the main body frame 11. When the side door 12 is closed, at this time, the L-shaped top plate 56 cancels the deflection limit on the deflection support legs 54. When the conveying mechanism automatically hooks the collar 43 for lateral movement, the deflection support legs 54 deflect by using the bearing shaft 53, thereby avoiding the inclination and shaking of the storage rack 1 due to lateral friction. After the storage rack 1 is conveyed to the loading area, the deflection support legs 54 self-reset for supporting unloading.
