[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: a conveyor roller for irradiating low-density products, including a fixed frame 1 and a connecting rod 11, a support plate 3 is arranged on the left and right sides of the bottom of the fixed frame 1, an open groove 4 is opened on the top of the support plate 3, a servo motor 5 is fixedly connected to the front side of the support plate 3, the output end of the servo motor 5 passes through the open groove 4 and is fixedly connected to a bidirectional screw rod 6, the front and rear sides of the outer walls of the two bidirectional screw rods 6 are threadedly connected to movable blocks 7, the top of the movable block 7 is rotatably connected to a first rotating shaft 8, and the front and rear ends of the left and right sides of the bottom of the fixed frame 1 are fixedly connected to U-shaped plates 9 The U-shaped plate 9 is internally rotatably connected with a second rotating shaft 10, and a plurality of second rotating shafts 10 are respectively connected with the corresponding first rotating shafts 8 through connecting rods 11. A limiting mechanism 2 is provided at the inner bottom of the fixed frame 1. The two movable blocks 7 are both slidably connected with the inside of the opening groove 4. The rear ends of the two bidirectional screw rods 6 are respectively rotatably connected with the rear sides of the corresponding opening grooves 4. A servo motor 12 is fixedly connected to the left side of the front end of the fixed frame 1. The output end of the servo motor 12 passes through the fixed frame 1 and is fixedly connected with a first rotating roller 13. A plurality of second rotating rollers 14 are rotatably connected to the inner side of the fixed frame 1 at equal intervals.

[0031] Specifically, the servo motor 5 drives the bidirectional screw 6 to rotate, and the movable block 7 outside the bidirectional screw 6 will move toward the middle, and the first rotating shaft 8 will rotate accordingly, and the second rotating shaft 10 is connected to the first rotating shaft 8 through the connecting rod 11. When the first rotating shaft 8 rotates, the connecting rod 11 will drive the second rotating shaft 10 to rotate accordingly, so that the fixed frame 1 can be lifted up, and the height and inclination angle of the roller can be adjusted at this time, so as to ensure that the product maintains a stable position during transportation. This adjustment can not only avoid the position deviation or tilt of the product during transportation, but also ensure that the effect of irradiation treatment is not affected.

[0032] Reference Figure 1 , Figure 2 and Figure 4 The limiting mechanism 2 includes a hollow block 201, which is fixedly connected to the inner bottom of the fixed frame 1, and a micro motor 202 is fixedly connected to the inner bottom of the hollow block 201. The output end of the micro motor 202 is fixedly connected to a gear 203. Slide grooves 204 are provided on the left and right sides of the hollow block 201. A slider 205 is slidably connected inside the slide groove 204. Racks 206 are fixedly connected to the adjacent sides of the two sliders 205. The two racks 206 are respectively meshed with the left and right sides of the gear 203. A U-shaped block 207 is fixedly connected to the away side of the two racks 206. The away ends of the two U-shaped blocks 207 respectively penetrate the hollow block 201 and the fixed frame 1 in sequence and are fixedly connected to a U-shaped frame 208. A plurality of rollers 209 are equidistantly connected to the adjacent sides of the two U-shaped frames 208.

[0033] Specifically, when the micro motor 202 is started, it drives the gear 203 to start rotating. The gear 203 is tightly meshed with the rack 206, so the rack 206 will move toward the middle inside the slide 204. As the rack 206 moves, the U-shaped blocks 207 on both sides will follow its movement, further driving the U-shaped frame 208 to move toward the middle. In this way, the U-shaped frame 208 can limit and clamp the product to be processed placed therein. In addition, a roller 209 is also provided inside the U-shaped frame 208, which can conveniently transport the product. This design not only improves the product's ability to correct deviation, but also effectively prevents the product from falling off the roller, thereby greatly improving the practicality of the device.

[0034] Reference Figure 1 and Figure 2 A connection frame 15 is fixedly connected to the middle of the top of the fixed frame 1, and a radiation source 16 is fixedly connected to the inner top of the connection frame 15;

[0035] Specifically, the radiation source 16 can be used to conveniently perform irradiation treatment on the product.

[0036] Reference Figure 1A controller 17 is fixedly connected to the right side of the front end of the fixed frame 1. The controller 17 is electrically connected to the micro motor 202, the servo motor 5, the servo motor 12 and the radiation source 16 respectively. A protective cover 18 is arranged on the outside of the controller 17. One side of the protective cover 18 is rotatably connected to the front end of the fixed frame 1.

[0037] Specifically, the operation of the micro motor 202, the servo motor 5, the servo motor 12 and the radiation source 16 can be controlled by the controller 17, and the protective cover 18 can protect the controller 17 from being damaged by external factors.

[0038] Working principle: When using the device, first put the product to be irradiated on the roller, then the servo motor 12 can drive the first roller 13 to rotate, and the second roller 14 will rotate accordingly to transport the product until the product is transported to the bottom of the radiation source 16. At this time, the radiation source 16 can irradiate the product, and the servo motor 5 can drive the bidirectional screw rod 6 to rotate, and the movable block 7 on the outside of the bidirectional screw rod 6 will move toward the middle. At this time, the first rotating shaft 8 will rotate accordingly, and the second rotating shaft 10 will also rotate through the connecting rod 11, so that the fixed frame 1 can be lifted up. At this time, the height and inclination angle of the roller can be adjusted to ensure that the product is transported. Maintaining a stable position, avoiding position deviation or tilting, and thus not affecting the irradiation effect, can meet the needs of users, and when the irradiated product is placed on the roller, the micro motor 202 can drive the gear 203 to rotate, and the rack 206 will move toward the middle inside the slide 204 due to the engagement with the gear 203, and the U-shaped blocks 207 on both sides will move along, thereby driving the U-shaped frame 208 to move toward the middle to limit the clamping of the product to be processed, and the roller 209 provided can facilitate the conveying of the product, so that the deviation correction operation can be performed on products of different sizes, so that it is not easy to fall off the roller, thereby improving the practicality of the device.
