Description

Technical Field

[0001] This utility model belongs to the field of electron accelerator technology, specifically relating to an easy-to-maintain electron accelerator irradiation device. Background Technology

[0002] Electron accelerator irradiation is a technology that uses high-energy electron beams to irradiate matter. This technology has a wide range of applications in many fields. Electron beam irradiation can kill bacteria, viruses and parasites in food, extend the shelf life of food, and at the same time, it does not significantly change the nutritional components and flavor of food. Electron accelerator irradiation is a safe and effective food preservation method.

[0003] The prior art patent publication number CN220106046U describes an easy-to-maintain electron accelerator irradiation device. This patent includes an electron accelerator housed inside a constant-temperature frame. A cover plate is hinged to the rear of the top of the constant-temperature frame. Connecting plates are fixedly connected to both sides of the electron accelerator. A limiting frame adapted to the connecting plates is fixedly connected to the bottom of the cover plate. By pulling two sliding rods upwards, the two sliding rods disengage from the limiting holes on the connecting plates and limiting frames, preventing them from jamming the connecting plates and limiting frames, thus facilitating the disassembly and maintenance of the electron accelerator. However, in practical use, the following shortcomings remain: From a practical standpoint, the height of this irradiation device is not easily adjustable, and its height cannot be adjusted according to the height of food packaging boxes, limiting its production adaptability and failing to meet the needs of multi-specification packaging.

[0004] Therefore, there is a need for an easy-to-maintain electron accelerator irradiation device to solve the problem of limited production adaptability caused by the inconvenience of adjusting the height of the irradiation device in the existing technology. Utility Model Content

[0005] The purpose of this invention is to provide an easy-to-maintain electron accelerator irradiation device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an easy-to-maintain electron accelerator irradiation device, comprising two mounting plates, each mounting plate having two quick-release mechanisms on its top, a protective frame detachably connected to the top of each mounting plate, two connecting plates fixedly connected to both sides of the protective frame, and latches corresponding to the quick-release mechanisms fixedly connected to the bottom of multiple connecting plates, with openings at the front and rear ends of the protective frame, and a lifting irradiation mechanism provided inside the protective frame.

[0007] It should be noted in the solution that the quick-release mechanism includes a snap-fit ​​groove fixedly connected to the top of the mounting plate, a rotating shaft rotatably connected between the inner walls of the front and rear ends of the snap-fit ​​groove, a locking rod fixedly connected to the outer wall of the rotating shaft, a first spring top block fixedly connected to one side of the bottom upper surface of the snap-fit ​​groove, a second spring top block fixedly connected to the other side of the bottom upper surface of the snap-fit ​​groove, and a sliding plate slidably connected to the inner wall of the snap-fit ​​groove.

[0008] It is worth noting that the top of the first spring top block is fixedly connected to the bottom of the locking rod near the outer side.

[0009] Furthermore, it should be noted that the inner wall of the snap-fit ​​groove is provided with a limiting groove corresponding to the slide plate, and the slide plate is located on the side close to the top of the first spring block.

[0010] In a preferred embodiment, the lifting irradiation mechanism includes a first support plate and a second support plate fixedly connected to the inner wall of the protective frame. A guide column is fixedly connected between the lower top surface of the protective frame and the top of the first support plate. A threaded rod is rotatably connected between the lower top surface of the protective frame and the top of the second support plate. A guide sleeve is slidably connected to the outer wall of the guide column. A ball nut seat is rotatably connected to the outer wall of the threaded rod. A horizontal plate is fixedly connected to the outer walls of the guide sleeve and the ball nut seat. A column is fixedly connected to the bottom of the horizontal plate. An electron accelerator body is fixedly connected to the bottom of the column. A servo motor is fixedly connected to the top of the protective frame.

[0011] In a preferred embodiment, the electron accelerator body is mounted to the bottom of the column by fixing bolts.

[0012] In a preferred embodiment, the servo motor output tube passes through the protective frame and is fixedly connected to the threaded rod.

[0013] Compared with the prior art, the electron accelerator irradiation device provided by this utility model, which is easy to maintain, has at least the following beneficial effects:

[0014] (1) By setting up a quick-release mechanism and a locking buckle, the protective frame can be disassembled and assembled without the need for complicated tools. During operation, the sliding plate can release the locking rod from the locking buckle, and the reverse operation can lock it, greatly shortening the disassembly and assembly time. At the same time, the electron accelerator body is installed at the bottom of the column by fixing bolts. The steps are simple when disassembling the body alone, which makes it easy for staff to inspect and replace it, reducing the difficulty of maintenance operations.

[0015] (2) By setting up a lifting irradiation mechanism, the servo motor drives the threaded rod to rotate, which can drive the ball nut seat, the horizontal plate and the electron accelerator body to move up and down, so as to achieve precise height adjustment. During the adjustment process, the guide column and the guide sleeve cooperate to ensure the stable movement of the horizontal plate and avoid the electron accelerator body from shifting. It can be adapted to food packaging boxes of different heights, meet the production needs of multiple specifications, and improve the practicality of the device. Attached Figure Description

[0022] The present invention will be further described below with reference to the embodiments.

[0023] Please see Figure 1-5 This utility model provides an easy-to-maintain electron accelerator irradiation device, including two mounting plates 1. Each mounting plate 1 is provided with two quick-release mechanisms 2 on its top. A protective frame 3 is detachably connected to the top of the two mounting plates 1. Two connecting plates 4 are fixedly connected to both sides of the protective frame 3. Each of the connecting plates 4 is fixedly connected to a latch 5 corresponding to the quick-release mechanism 2 at its bottom. The protective frame 3 has openings 6 at both its front and rear ends. A lifting irradiation mechanism 7 is provided inside the protective frame 3.

[0024] Further as Figure 4As shown, it is worth noting that the quick-release mechanism 2 includes a snap-fit ​​groove 201 fixedly connected to the top of the mounting plate 1. A rotating shaft 202 is rotatably connected between the inner walls of the front and rear ends of the snap-fit ​​groove 201. A locking rod 203 is fixedly connected to the outer wall of the rotating shaft 202. A first spring top block 204 is fixedly connected to one side of the bottom upper surface of the snap-fit ​​groove 201. A second spring top block 205 is fixedly connected to the other side of the bottom upper surface of the snap-fit ​​groove 201. A sliding plate 206 is slidably connected to the inner wall of the snap-fit ​​groove 201. By setting the quick-release mechanism 2 and the locking buckle 5 together, the installation and removal of the protective frame 3 can be completed without the need for complicated tools. During operation, sliding the sliding plate 206 can release the locking rod 203 from fixing the locking buckle 5, and reversing the operation can lock it, which greatly shortens the installation and removal time and facilitates the maintenance of the device.

[0025] Further as Figure 4 As shown, it is worth noting that the top of the first spring top block 204 is fixedly connected to the bottom of the locking rod 203 near the outer side, which can continuously apply an upward elastic force to the outer side of the locking rod 203, so that the locking rod 203 always remains tightly engaged with the latch 5, preventing the locking rod 203 from loosening due to its own weight or slight vibration of the device, and ensuring the stability of the connection between the protective frame 3 and the mounting plate 1.

[0026] Further as Figure 4 As shown, it is worth noting that the inner wall of the snap-fit ​​groove 201 is provided with a limiting groove corresponding to the slide plate 206. The limiting groove on the inner wall of the snap-fit ​​groove 201 is adapted to the slide plate 206, which can strictly constrain the sliding trajectory of the slide plate 206, preventing the slide plate 206 from shifting laterally or getting stuck when pushing the locking rod 203. This ensures that the slide plate 206 can act smoothly and accurately on the locking rod 203, thus ensuring the operational reliability of the quick-release mechanism 2. Furthermore, the slide plate 206 is located on the side close to the top of the first spring top block 204. This position allows the slide plate 206 to act directly on the end of the locking rod 203 near the first spring top block 204. When the slide plate 206 is slid, it can quickly push the inner side of the locking rod 203 downward, thereby causing the outer side of the locking rod 203 to tilt upward to disengage from the latch 5. There is no need to adjust the position of the slide plate 206, which shortens the unlocking operation time and improves the disassembly and assembly efficiency of the quick-release mechanism 2.

[0027] As can be seen from the above working process, by setting up the quick-release mechanism 2 and the locking buckle 5, the installation and removal of the protective frame 3 can be completed without the need for complicated tools. During operation, sliding the sliding plate 206 can release the locking rod 203 from fixing the locking buckle 5, and reversing the operation can lock it, which greatly shortens the installation and removal time and facilitates the maintenance of the device.

[0028] Further as Figure 5As shown, it is worth noting that the lifting irradiation mechanism 7 includes a first support plate 701 and a second support plate 702 fixedly connected to the inner wall of the protective frame 3. A guide post 703 is fixedly connected between the lower top surface of the protective frame 3 and the top of the first support plate 701. A threaded rod 704 is rotatably connected between the lower top surface of the protective frame 3 and the top of the second support plate 702. A guide sleeve 705 is slidably connected to the outer wall of the guide post 703. A ball nut seat 706 is rotatably connected to the outer wall of the threaded rod 704. A horizontal plate 707 is fixedly connected to the outer walls of the guide sleeve 705 and the ball nut seat 706. A vertical rod is fixedly connected to the bottom of the horizontal plate 707. The column 708 has an electron accelerator body 709 fixedly connected to its bottom, and a servo motor 710 fixedly connected to the top of the protective frame 3. By setting up a lifting irradiation mechanism 7, the servo motor 710 drives the threaded rod 704 to rotate, which can drive the ball nut seat 706, the horizontal plate 707 and the electron accelerator body 709 to move up and down, so as to achieve precise height adjustment. During the adjustment process, the guide column 703 and the guide sleeve 705 cooperate to ensure the stable movement of the horizontal plate 707 and prevent the electron accelerator body 709 from deviating. It can adapt to food packaging boxes of different heights, meet the needs of multi-specification production, and improve the practicality of the device.

[0029] Further as Figure 5 As shown, it is worth noting that the electron accelerator body 709 is installed at the bottom of the column 708 by fixing bolts. The steps for disassembling the electron accelerator body 709 are simple, making it easy for staff to inspect and replace it, thus reducing the difficulty of maintenance operations.

[0030] Further as Figure 5 As shown, it is worth noting that the output tube of the servo motor 710 passes through the protective frame 3 and is fixedly connected to the threaded rod 704. This allows the driving force of the servo motor 710 to be transmitted to the threaded rod 704 without loss, avoiding potential power attenuation or transmission delay issues in intermediate transmission components. This ensures that the threaded rod 704 can accurately respond to the start, stop, and speed commands of the servo motor 710, thereby enabling precise adjustment of the height of the electron accelerator body 709 to adapt to the irradiation requirements of different packaging sizes.

[0031] This solution has the following working process: In actual use, according to the height specifications of the food packaging box to be irradiated, the servo motor 710 at the top of the protective frame 3 is started. Its output shaft passes through the protective frame 3 and drives the threaded rod 704 to rotate. When the threaded rod 704 rotates, the ball nut seat 706 on the outer wall moves up and down along the rod body. At the same time, the guide sleeve 705 on the outer wall of the guide column 703 slides synchronously, driving the horizontal plate 707, which is fixedly connected to the two, to rise and fall smoothly. The column 708 at the bottom of the horizontal plate 707 moves accordingly, and finally adjusts the height of the electron accelerator body 709 at the bottom of the column 708 until it is adapted to the specifications of the food packaging box. The food packaging box to be irradiated is continuously fed through the openings 6 at the front and rear ends of the protective frame 3. The electron accelerator is placed inside the protective frame 3, below the electron accelerator body 709. The electron accelerator body 709 is then activated, and the high-energy electron beam it generates irradiates downwards, treating the food packaging materials during transport to kill bacteria, viruses, and parasites, thus preserving the food. If the electron accelerator body 709 needs to be inspected, the equipment can be turned off first. The sliding plate 206 in the quick-release mechanism 2 at the top of the mounting plate 1 can be slid to push the locking rod 203 to rotate around the rotating shaft 202 and disengage from the locking buckle 5 at the bottom of the connecting plate 4. The protective frame 3 can then be removed, and the fixing bolts connecting the column 708 and the electron accelerator body 709 can be unscrewed. The body can be disassembled separately for inspection. After inspection, the installation can be completed by reversing the operation.

[0032] In summary: By combining the quick-release mechanism 2 with the locking buckle 5, the protective frame 3 can be disassembled and assembled without the need for complex tools. During operation, sliding the sliding plate 206 releases the locking rod 203 from the locking buckle 5, and reversing the operation locks it, significantly shortening the disassembly and assembly time and facilitating device maintenance. By setting up the lifting irradiation mechanism 7, the servo motor 710 drives the threaded rod 704 to rotate, which can move the ball nut seat 706, the horizontal plate 707, and the electron accelerator body 709 up and down, achieving precise height adjustment. During the adjustment process, the guide column 703 and the guide sleeve 705 cooperate to ensure the stable movement of the horizontal plate 707 and prevent the electron accelerator body 709 from shifting. This allows it to adapt to food packaging boxes of different heights, meet the needs of multi-specification production, and improve the practicality of the device.

[0033] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
