Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to a continuous irradiation sterilization system. Background Art

[0002] High-energy electron beams generally refer to the high-energy electron beam currents generated by various medical accelerators for radiotherapy. Since an electron beam is a charged particle and the electric charge carried by each electron is determined, theoretically speaking, on the acceleration path, the energy of the high-energy electron beam current is only related to the intensity of the acceleration voltage. The higher the voltage, the higher the energy of the electron beam. Therefore, the energy of the high-energy electron beam is generally expressed by the nominal acceleration voltage, and the unit is megaelectron volt (MeV), such as 6 MeV electron beam, 10 MeV electron beam, etc. In industries such as food processing, pharmaceutical manufacturing, and medical supplies manufacturing, sterilization is a crucial step to ensure the safety of products and extend their shelf life. Traditional sterilization methods, such as thermal sterilization and chemical sterilization, although effective, may have an adverse impact on the quality of products. For example, they may change the taste, color, or nutritional value of food, or leave chemical residues on medical devices. Therefore, irradiation sterilization, as a "cold disinfection" technology, is favored because it does not change the physical properties of products.

[0003] Existing continuous irradiation sterilization systems usually adopt a single irradiation process, that is, materials enter the irradiation chamber through a conveyor belt for one-time irradiation treatment. However, in some cases, especially for those materials that require a higher sterilization level or special treatment, multiple irradiations may be required to achieve the desired sterilization effect. The existing systems lack an effective blanking device, which means that after one irradiation, on the annular conveyor belt, the materials will re-enter the irradiation process, resulting in the materials being unable to be effectively taken out automatically, causing multiple irradiations, which limits the support ability of the system for complex process requirements.

[0004] In addition, most existing continuous irradiation sterilization systems rely on manual operation during the lifting process of materials, which not only increases the workload of operators, but also reduces production efficiency. At the same time, it may also lead to inconsistencies in material handling due to human factors.

[0005] Now, the utility model designs a continuous irradiation sterilization system to solve the above technical problems. Summary of the Utility Model

[0006] The utility model provides a continuous irradiation sterilization system, aiming to solve the problem that materials cannot be effectively taken out automatically when multiple irradiations are required, resulting in multiple irradiations. The technical solution is as follows:

[0007] A continuous irradiation sterilization system includes a lifting device, a first conveying device, an irradiation chamber, an irradiation conveyor belt, a second conveying device and a blanking conveyor belt. The first conveying device, the irradiation conveyor belt and the second conveying device are connected end to end to form an endless conveyor belt, and the endless conveyor belt passes through the irradiation chamber.

[0008] The blanking conveyor belt includes a blanking support, a blanking guide rail, a first motor and a second motor. The blanking guide rail is fixedly connected to the blanking support. The first motor is fixedly connected to the blanking support. The first motor is connected to a sprocket to drive the chain to move. The first motor drives the tray to move on the blanking guide rail through the chain. A roller is also provided on the blanking support, and the second motor drives the roller to rotate through a gear transmission.

[0009] Based on the above technical solution, the roller is at the same height as the blanking guide rail.

[0010] Based on the above technical solution, the lifting device includes a lifting base, a lifting back plate and a moving plate. The lifting back plate is fixedly connected to the lifting base. A slide rail is fixedly connected to the lifting back plate. The lifting motor is fixedly connected to the lifting back plate. The output end of the lifting motor is connected to a driving wheel. A driven wheel is also provided on the lifting back plate. A belt is installed between the driving wheel and the driven wheel. A sliding block is installed on the belt. The sliding block slides on the slide rail. The moving plate is fixedly connected to the sliding block.

[0011] Preferably, the bottom of the tray has rollers, and the rollers are rollably supported on the chain.

[0012] Preferably, a baffle is provided on the lifting back plate.

[0013] Beneficial effects

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows: On the one hand, the system is designed with a dedicated blanking conveyor belt, which can take out materials from the endless conveyor belt as needed, avoiding the problem that materials automatically re-enter the irradiation process after one irradiation. In this way, the irradiation times of the materials can be accurately controlled to ensure the required sterilization effect without worrying about multiple unnecessary irradiations. On the other hand, the lifting device realizes the automatic lifting of materials, reducing the work burden of operators and improving production efficiency at the same time. Automated processing reduces the time and error rate of manual intervention, making the entire production process smoother. Description of the drawings

[0024] Marks are provided on the packaging of the material to be irradiated to record the number of irradiations and prevent repeated irradiation.

[0025] As Figure 1 shown, a continuous irradiation sterilization system is characterized in that it comprises a lifting device 1, a first conveying device 2, an irradiation chamber 3, an irradiation conveyor belt 4, a second conveying device 5 and a blanking conveyor belt 6. The first conveying device 2, the irradiation conveyor belt 4 and the second conveying device 5 are connected end to end to form an endless conveyor belt, and the endless conveyor belt passes through the irradiation chamber 3. The first conveying device 2, the irradiation conveyor belt 4, the second conveying device 5 and the blanking conveyor belt 6 are all provided with driving devices.

[0026] As Figure 2 shown, the blanking conveyor belt 6 comprises a blanking support, a blanking guide rail 61, a first motor 62 and a second motor 65. The blanking guide rail 61 is fixedly connected to the blanking support. The first motor 62 is fixedly connected to the blanking support, and the first motor 62 is connected to a sprocket 63 to drive the chain to move. The first motor 62 drives a tray 7 to move on the blanking guide rail 61 through the chain. A roller 64 is further arranged on the blanking support, and the second motor 65 drives the roller 64 to rotate through gear transmission. The first motor 62 transmits power to the main sprocket, the main sprocket transmits power to the driven sprocket through a chain or a belt, the driven sprocket moves the chain through a gear, the second motor 65 transmits power to the driving gear, the driving gear is belt-connected to the driven gear, gears are arranged at the ends of the rollers on the roller 64, the gears are engaged with each other to transmit power to the roller 64, and the friction force generated by the rotation of the roller 64 pushes the materials placed on it forward.

[0027] The roller 64 is at the same height as the blanking guide rail 61, which can reduce the bumps or jams of the materials caused by the height difference during the transfer process, so as to ensure the smooth transition of the materials.

[0028] The bottom of the tray 7 is provided with rollers, and the rollers are rollably supported on the chain. In order to avoid the wear of the chain, these rollers can be embedded within the chain pitch and roll along with the movement of the chain, thereby reducing friction and wear. In addition, the rollers can also improve the overall efficiency and reliability of the system.

[0029] As Figure 3 and Figure 4As shown in the figure, the lifting device 1 includes a lifting base 11, a lifting back plate 12 and a moving plate 18. The lifting back plate 12 is fixedly connected to the lifting base 11. A slide rail 121 is fixedly connected to the lifting back plate 12. A lifting motor 13 is fixedly connected to the lifting back plate 12. The output end of the lifting motor 13 is connected to a driving wheel 14. A driven wheel 15 is also arranged on the lifting back plate 12. A belt 16 is installed between the driving wheel 14 and the driven wheel 15. A sliding block 17 is installed on the belt 16. The sliding block 17 slides on the slide rail 121. The moving plate 18 is fixedly connected to the sliding block 17. An outer shell 10 is connected to the lifting base 11 and the lifting back plate 12. The outer shell 10 can prevent dust from entering the lifting motor 13. When the lifting device 1 breaks down, the outer shell 10 can be opened for maintenance.

[0030] A baffle 181 is arranged on the lifting back plate 12. The baffle 181 surrounds the moving plate 18. According to the shape of the material, slots can be opened on the baffle 181 to make the material move smoothly during the up and down movement.

[0031] A belt conveyor 66 is arranged on the blanking support. The pallet 7 is transported onto the belt conveyor 66 after passing through the sprocket 63, and the next process can be continued, or various other conveying methods can also be used.

[0032] During use, the material is loaded onto the pallet 7. The bottom of the pallet is provided with rollers and can roll on the chain. Marks are set on the material packages on each pallet 7 to record the number of irradiation times and prevent repeated irradiation.

[0033] The material is lifted to an appropriate height by the lifting device 1. When the moving plate 18 rises to an appropriate height, the pallet 7 is on the same horizontal plane as the first conveying device 2. A manipulator or other conveying mechanism is used to smoothly transfer the pallet 7 from the moving plate 18 to the first conveying device 2.

[0034] The pallet 7 is located on the first conveying device 2, and the driving device of the first conveying device 2 is started.

[0035] The material is sent into the annular conveyor belt through the first conveying device 2 and leads to the irradiation chamber 3. After being sterilized in the irradiation chamber 3 and completing one irradiation, the material passes through the irradiation conveyor belt 4 and goes around to the second conveying device 5. If further irradiation is required, the second motor 65 is driven to transport the pallet from the roller 64 to the first conveying device 2 and continue to enter the irradiation chamber 3. If the irradiation is completed, the second motor 65 stops working and the first motor 62 works to transport the pallet 7 from the chain to the belt conveyor 66, and the next process can be continued.

[0036] The present invention has been described by way of example, but the present invention is not limited to the above specific embodiments. Any modification or variation based on the present invention falls within the scope of protection required by the present invention.
