Description

Technical Field

[0001] This utility model relates to the field of electron beam irradiation sterilization technology, specifically a high-energy electron beam irradiation sterilization device. Background Technology

[0002] Irradiation sterilization technology is an effective method for killing harmful bacteria and microorganisms by using radiation. With advancements in technology, irradiation sterilization technology has matured and is widely used in various fields such as food, medicine, and materials. High-energy electron beam irradiation sterilization, as a type of irradiation sterilization technology, is gaining increasing popularity due to its advantages such as high efficiency, no residue, and environmental friendliness.

[0003] Currently, existing electron beam irradiation sterilization devices typically sterilize square objects or boxes by placing the objects on a conveyor belt and transporting them into the sterilization chamber, where an electron beam generator emits radiation to sterilize the objects. However, the surfaces of the objects that come into contact with the conveyor belt cannot directly contact the radiation, resulting in poor sterilization. Therefore, a high-energy electron beam irradiation sterilization device is proposed. Utility Model Content

[0004] The main objective of this invention is to provide a high-energy electron beam irradiation sterilization device that addresses the problems raised in the background section above.

[0005] To achieve the above objectives, the present invention proposes a high-energy electron beam irradiation sterilization device, comprising a sterilization chamber fixedly mounted on a support frame, a transfer roller rotatably connected to the support frame, a transfer belt drivingly connected to the transfer roller, an adjustment opening structure provided on the outer wall of the sterilization chamber, an electron beam generator fixedly mounted in the sterilization chamber, and a flipping mechanism provided in the sterilization chamber, the flipping mechanism comprising:

[0006] An adjustment structure is provided in the sterilization chamber;

[0007] An electric telescopic rod, wherein the electric telescopic rod is connected to an adjustment structure, and a flipping frame is rotatably connected to the telescopic end of the electric telescopic rod;

[0008] A connecting frame is fixedly connected to the telescopic end of the electric telescopic pole.

[0009] Preferably, the connecting frame is provided in two sets, and the two sets of connecting frames are symmetrically arranged with the center line of the electric telescopic rod as the axis of symmetry. Each set of connecting frames is rotatably connected to a set of flipping frames. By using the flipping frames, after the conveyor belt transports the square object to the flipping frame for contact, the square object is driven to flip under the action of inertia, so that the square component is flipped. By using the three sets of flipping frames, the bottom surface of the object can be flipped to the top, which is convenient for sterilizing the bottom of the object and improving the sterilization effect of the object.

[0010] Preferably, a guide rod is fixedly connected to the outer wall of the connecting frame, the guide rod passes through the fixing block and is slidably connected to the fixing block, and the fixing block is fixedly connected to the sleeve part of the electric telescopic rod.

[0011] Preferably, the adjustment structure includes a fixed base, a bidirectional lead screw, and a threaded block. The bidirectional lead screw is rotatably connected to the fixed base, and the threaded block is threadedly connected to the bidirectional lead screw. The threaded block is slidably connected to the inner surface of the fixed base and fixed to an electric telescopic rod. The bidirectional lead screw is driven by a motor, which is fixedly connected to the outer wall of the sterilization chamber. By driving the bidirectional lead screw to rotate, the threaded block moves. In conjunction with the use of the electric telescopic rod, the position of the turning frame can be adjusted, making it convenient to turn over objects of different sizes.

[0012] Preferably, a counterweight is embedded in the flipping frame, and the counterweight is located at the end of the flipping frame.

[0013] Preferably, the conveyor belt is provided in multiple sets, and the multiple sets of conveyor belts are arranged in an equidistant array. The distance between the conveyor belts is greater than the sum of the thickness of the flipping frame and the connecting frame. By using counterweights, the face of the flipping frame can remain horizontal or vertical with the conveyor belt after the flipping is completed, preventing tilting and ensuring that the object is stably moved onto the flipping frame for flipping.

[0014] Preferably, the adjustable opening structure includes a guide rail, the outer wall of which is fixedly connected to the outer wall of the sterilization chamber. A protective plate is slidably connected to the guide rail, and a clamping bolt is threaded onto the guide rail. By rotating the clamping bolt, the protective plate can be fixed or released from its limiting position, and the height of the protective plate can be adjusted, thereby adjusting the opening size of the sterilization chamber.

[0015] This invention provides a high-energy electron beam irradiation sterilization device. It has the following beneficial effects:

[0016] (1) The high-energy electron beam irradiation sterilization device uses the cooperation of the flipping frame and the conveyor belt to drive the flipping frame to flip by the inertia of the object to flip the bottom surface of the square object to the top, so as to facilitate the sterilization of the bottom of the object. This solves the problem of sterilization dead corner caused by the bottom surface of the object contacting the conveyor belt in traditional devices, and achieves sterilization without dead corners, thus improving the sterilization effect.

[0017] (2) The high-energy electron beam irradiation sterilization device uses an adjustable structure. The motor drives the bidirectional lead screw to rotate, which in turn moves the threaded block. Under the extension and retraction of the electric telescopic rod, the lateral position of the flipping frame is adjusted, which can adapt to the flipping requirements of square objects or boxes of different lengths and widths. It can handle items of various specifications without changing the hardware, avoiding the flipping failure problem caused by the difference in the size of the object in the traditional device, and enhancing the versatility of the equipment and the flexibility of production.

[0018] (3) The high-energy electron beam irradiation sterilization device, through the use of counterweights, can ensure that the face of the flipping frame is horizontal or vertical to the conveyor belt after the flipping is completed, preventing tilting and ensuring that the object is stably moved to the flipping frame for flipping. At the same time, by adjusting the opening structure, the size of the sterilization chamber entrance can be adjusted according to the height of the object, which can reduce the meaningless scattering of radiation and adapt to the entry and exit of items of different heights.

[0028] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-6 This utility model proposes a high-energy electron beam irradiation sterilization device, including a sterilization chamber 1, which is fixedly installed on a support frame 2. A transmission roller is rotatably connected to the support frame 2, and a transmission belt 3 is drivenly connected to the transmission roller. An adjustment opening structure 4 is provided on the outer wall of the sterilization chamber 1. An electron beam generating device 5 is fixedly installed in the sterilization chamber 1, and a flipping mechanism 6 is provided in the sterilization chamber 1.

[0031] In this embodiment of the invention, in order to sterilize the square object by flipping the bottom surface of the contact area between the object and the conveyor belt 3, the flipping mechanism 6 specifically includes an adjustment structure, an electric telescopic rod 65, and a connecting frame 67. The adjustment structure is installed in the sterilization chamber 1. The electric telescopic rod 65 is connected to the adjustment structure. A flipping frame 66 is rotatably connected to the telescopic end of the electric telescopic rod 65. The connecting frame 67 is fixedly connected to the telescopic end of the electric telescopic rod 65. Two sets of connecting frames 67 are provided, and the two sets of connecting frames 67 are symmetrically arranged about the center line of the electric telescopic rod 65. A set of flipping frames 66 is rotatably connected to each set of connecting frames 67. 3. Multiple sets of conveyor belts 3 are arranged in an equidistant array. The distance between the conveyor belts 3 is greater than the sum of the thicknesses of the flipping frame 66 and the connecting frame 67. The flipping frame 66 is located between the distances of two conveyor belts 3. In this way, when the flipping frame 66 flips the object, it will not affect the conveying of the conveyor belt 3. Through the cooperation of the flipping frame 66 and the conveyor belt 3, the inertia of the object is used to drive the flipping frame 66 to flip, so that the bottom surface of the square object that is in contact with the conveyor belt 3 is flipped to the top, which is convenient for sterilizing the bottom of the object. This solves the problem of sterilization dead corners caused by the bottom surface of the object contacting the conveyor belt 3 in traditional devices, and achieves sterilization without dead corners, thus improving the sterilization effect.

[0032] Furthermore, a guide rod 68 is fixedly connected to the outer wall of the connecting frame 67. The guide rod 68 passes through the fixed block and is slidably connected to the fixed block. The fixed block is fixedly connected to the sleeve part of the electric telescopic rod 65. Through the use of the guide rod 68 and the fixed block, the movement of the flipping frame 66 can remain stable when the telescopic end of the electric telescopic rod 65 is telescopic.

[0033] Furthermore, to accommodate the flipping of objects of different sizes, the adjustment structure specifically includes a fixed base 61, a bidirectional lead screw 62, and a threaded block 63. The bidirectional lead screw 62 is rotatably connected to the fixed base 61, and the threaded block 63 is threadedly connected to the bidirectional lead screw 62. The threaded block 63 is slidably connected to the inner surface of the fixed base 61 and is fixed to the electric telescopic rod 65. The bidirectional lead screw 62 is driven by a motor 64, which is fixedly connected to the outer wall of the sterilization chamber 1. By driving the bidirectional lead screw 62 to rotate, the threaded block 63 moves. With the use of the electric telescopic rod 65, the adjustable flipping frame 66 can be positioned between different pairs of conveyor belts 3, facilitating the flipping of objects of different sizes. This avoids the flipping failure problem caused by differences in object size in traditional devices, enhancing the equipment's versatility and production flexibility.

[0034] Furthermore, a counterweight 661 is embedded in the flipping frame 66 and is located at the end of the flipping frame 66. By using the counterweight 661, the face of the flipping frame 66 can remain horizontal or vertical with the conveyor belt 3 after flipping, preventing tilting and ensuring that the object moves stably onto the flipping frame 66 for flipping.

[0035] Furthermore, the adjustable opening structure 4 includes a guide rail 41, which is fixedly connected to the outer wall of the sterilization chamber 1. A protective plate 42 is slidably connected to the guide rail 41, and a clamping bolt 43 is threadedly connected to the guide rail 41. By rotating the clamping bolt 43, the protective plate 42 can be fixed or released from its protective position, and the height of the protective plate 42 can be adjusted, thereby adjusting the opening size of the sterilization chamber 1. This can reduce the meaningless scattering of radiation and accommodate items of different heights entering and exiting.

[0036] It should be noted that the above electrical components are all existing technology products. Those skilled in the art should select, install and complete the circuit debugging work according to the needs of use to ensure that all electrical appliances can work normally. The components are all general standard parts or components known to those skilled in the art. Their structure and principle can be known by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are made here.

[0037] In use, first, depending on the size of the object, start the motor 64 to drive the bidirectional lead screw 62 to rotate, causing the threaded block 63 to move. With the use of the electric telescopic rod 65, the flipping frame 66 can be adjusted to be positioned between different pairs of conveyor belts 3. Then, through the cooperation between the flipping frame 66 and the conveyor belt 3, the inertia of the object's transmission is used to drive the flipping frame 66 to flip, so that the bottom surface of the square object in contact with the conveyor belt 3 is flipped to the top, which is convenient for sterilizing the bottom of the object. After the flipping frame 66 has finished flipping, its frame surface can remain horizontal or vertical with the conveyor belt 3 to prevent tilting, so that the object can be stably moved onto the flipping frame 66 for flipping.
