Abstract
Description
Technical Field
[0001] This utility model relates to the field of irradiation device technology, and more specifically, to a high-dose product uniform irradiation device. Background Technology
[0002] Irradiation, a novel sterilization and preservation technology, uses (cesium-137, cobalt-60, etc., which affect DNA) to sterilize and deactivate grains, vegetables, fruits, meats, condiments, and pharmaceuticals. For example, patent application number CN202111618387 describes a plate irradiation device for irradiating plates. The device includes a shield, an electron accelerator positioned above the shield, and a transmission device for moving the plate within the shield. The shield is hollow and divided into an irradiation zone and two shielding zones on either side of the irradiation zone. Each shielding zone has at least two shielding doors, which have a first state of being open to allow the plate to pass through and a second state of being closed to shield radiation. The plate irradiation device of the present invention employs multiple shielding doors, enabling the front shielding door to automatically open and the rear shielding door to automatically close as the plate is continuously advanced and irradiated. This allows for continuous, uninterrupted irradiation of plates of different sizes, ensuring shielding effectiveness while reducing the overall length of the equipment and improving production line efficiency. In contrast, the above-mentioned technical solutions, when processing large-sized products, can only irradiate one surface of the product. This results in a greater absolute difference between the maximum and minimum absorbed doses of the product as the irradiation dose increases, leading to significant differences in irradiation effects and wasted production capacity. Utility Model Content
[0003] The main objective of this invention is to provide a high-dose product uniform irradiation device, which can effectively solve the problem in the background technology that, during the processing of some large-sized products, only one surface of the product can be irradiated, resulting in a greater absolute difference between the maximum and minimum values of the absorbed dose as the irradiation dose increases, thus leading to large differences in the irradiation effect of the product and wasted production capacity.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a high-dose product uniform irradiation device, including a support frame, a roller conveyor arranged between the inner walls of the support frame, a base frame installed on the lower surface of the support frame, mounting side plates fixedly installed on both sides of the base frame, a top plate fixedly installed between the top ends of the two mounting side plates, an irradiator installed on the top plate, and a positioning and flipping assembly provided on the mounting side plates.
[0005] Preferably, positioning clamps are slidably installed on both sides of the upper surface of the support frame.
[0006] Preferably, the upper surface of the support frame is provided with a sliding groove, and the inner surface of the sliding groove is provided with a plurality of bolt holes at equal intervals. Two sliders are slidably installed inside the sliding groove. The two sliders are respectively connected to two positioning clamps. Bolts are installed on the upper surface of the two positioning clamps, and the top of the bolts is located inside the bolt holes.
[0007] Preferably, the positioning and flipping assembly includes a limiting plate and a through slot. The limiting plate is fixedly installed on one side surface of the top plate, and the through slot is opened through the surface of the mounting side plate.
[0008] Preferably, a hydraulic cylinder is fixedly installed on the lower surface of the limiting plate, a connecting plate is installed on the output end of the hydraulic cylinder, a first servo motor is fixedly installed on the lower surface of the connecting plate, a bidirectional lead screw is installed on the output end of the first servo motor, and two lead screw sleeves are sleeved on the middle of the bidirectional lead screw.
[0009] Preferably, a positioning plate is fixedly installed on the circumference of both lead screw sleeves, and a through block is fixedly installed on one end of the positioning plate.
[0010] Preferably, the through block moves through the through slot, and a second servo motor is fixedly installed at the top of the through block, with a clamping plate installed at the output end of the second servo motor.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] (1) The bidirectional lead screw is driven to rotate by the output end of the first servo motor. This drives the two lead screw sleeves to move towards each other, which in turn drives the two positioning plates to move towards each other and the two clamping plates to move towards each other. The two clamping plates are then placed on the two sides of the product to fix it in place. The hydraulic cylinder is then extended and retracted, which drives the connecting plate to move upward and the two clamping plates to move upward, thus moving the product upward. After the product is moved to a suitable height, the two clamping plates are driven to rotate by the output ends of the two second servo motors, which in turn drives the product to rotate, allowing the irradiator to irradiate the product from all sides and to irradiate it evenly, thereby improving the irradiation quality of the device.

[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.
[0019] like Figure 1 As shown, a high-dose product uniform irradiation device includes a support frame 1, a roller conveyor 12 disposed between the inner walls of the support frame 1, a base frame 2 mounted on the lower surface of the support frame 1, mounting side plates 4 fixedly mounted on both sides of the base frame 2, a top plate 6 fixedly mounted between the top ends of the two mounting side plates 4, an irradiator 7 mounted on the top plate 6, and a positioning and flipping assembly 3 disposed on the mounting side plates 4.
[0020] like Figure 1 , 2 As shown, positioning clamps 5 are slidably installed on both sides of the upper surface of the support frame 1. A sliding groove 8 is provided on the upper surface of the support frame 1. A plurality of bolt holes 10 are equidistantly provided on the inner surface of the sliding groove 8. Two sliders 9 are slidably installed inside the sliding groove 8. The two sliders 9 are respectively connected to the two positioning clamps 5. Bolts 11 are installed on the upper surface of the two positioning clamps 5. The top of the bolt 11 is set inside the bolt hole 10. By sliding the two positioning clamps 5, the distance between the two positioning clamps 5 is adjusted to a suitable distance. Then, by rotating the bolt 11, the top of the bolt 11 is set inside the bolt hole 10, which fixes the two positioning clamps 5.
[0021] like Figure 2 , 3As shown in Figure 4, the positioning and flipping assembly 3 includes a limiting plate 301 and a through groove 308. The limiting plate 301 is fixedly installed on one side surface of the top plate 6. The through groove 308 is opened through the surface of the mounting side plate 4. A hydraulic cylinder 302 is fixedly installed on the lower surface of the limiting plate 301. A connecting plate 303 is installed at the output end of the hydraulic cylinder 302. A first servo motor 304 is fixedly installed on the lower surface of the connecting plate 303. A bidirectional lead screw 305 is installed at the output end of the first servo motor 304. Two lead screw sleeves 306 are sleeved in the middle of the bidirectional lead screw 305. Positioning plates 307 are fixedly installed on the circumference of both lead screw sleeves 306. A through block 309 is fixedly installed at one end of the positioning plate 307. The through block 309 moves through the through groove 308. A second servo motor 310 is fixedly installed at the top of the through block 309. A clamping plate 311 is installed at the output end of the second servo motor 310. The output of the first servo motor 304 drives the bidirectional lead screw 305 to rotate, which in turn drives the two lead screw sleeves 306 to move closer together, thereby driving the two positioning plates 307 to move closer together, and then driving the two clamping plates 311 to move closer together, placing the two clamping plates 311 on both sides of the product to fix the product. At this time, the output of the hydraulic cylinder 302 extends and retracts, which drives the connecting plate 303 to move upward, thereby driving the two clamping plates 311 to move upward, and thus moving the product upward. After the product is moved to a suitable height, the outputs of the two second servo motors 310 drive the two clamping plates 311 to rotate, thereby driving the product to rotate, so that the irradiator 7 can irradiate the product from all sides and evenly, improving the irradiation quality of this device.
[0022] The working principle of a high-dose product uniform irradiation device:
[0023] In use, when this device is needed to irradiate a product, the two positioning clamps 5 are slid together to adjust the distance between them. Then, the bolt 11 is rotated to fix its tip inside the bolt hole 10, thus securing the two positioning clamps 5. The product is then placed between the two positioning clamps 5 on the upper surface of the roller conveyor 12. The roller conveyor 12 then moves the product. When the product is moved to the lower end of the irradiator 7, the irradiator 7 irradiates the product. The output of the first servo motor 304 drives the bidirectional lead screw 305 to rotate, which in turn drives the two lead screw sleeves 306 to move closer together. The movement of the two positioning plates 307 and the two clamping plates 311 can drive the two positioning plates 307 to move closer to each other, thus fixing the product on both sides. At this time, the hydraulic cylinder 302 extends and retracts, which drives the connecting plate 303 to move upward, and then drives the two clamping plates 311 to move upward, thus moving the product upward. After the product is moved to a suitable height, the two clamping plates 311 are driven to rotate by the output of the two second servo motors 310, which drives the product to rotate, so that the irradiator 7 can irradiate the product from all sides and evenly, thus improving the irradiation quality of the device.
[0024] The above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
