[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Example: Please refer to Figures 1-5 This utility model provides a technical solution:

[0027] A foreign object detection device for spring roll filling includes a conveyor frame 1 and an X-ray detector 2 fixedly installed on the conveyor frame 1. Positioning mechanisms 3 are installed at both ends of the conveyor frame 1 and in front of the X-ray detector 2. A height limiting mechanism 4 is installed between the positioning mechanism 3 and the X-ray detector 2. A discharge hood 5 is fixedly installed at the rear end of the X-ray detector 2.

[0028] First, in this embodiment, the specific structure of the positioning mechanism 3 is as follows:

[0029] The positioning mechanism 3 includes first cylinders 301 fixedly installed at the left and right ends of the conveyor frame 1. Connecting plates 302 are fixedly installed on the driving ends of both sets of first cylinders 301. Slide rods 303 are fixedly installed on opposite sides of both sets of connecting plates 302. Springs 304 are sleeved at both ends of the slide rods 303. Sliding sleeves 305 are slidably connected to the outer sides of the slide rods 303 and at the opposite ends of the two sets of springs 304. Transmission rods 306 are rotatably connected to the outer sides of both sets of sliding sleeves 305. A connector 307 is rotatably connected between the two sets of transmission rods 306. A positioning plate 308 is fixedly installed at the end of the connector 307 away from the transmission rod 306. When inspecting the spring roll filling, after placing the packaging bag at the front end of the conveyor frame 1, the first cylinders 301 are activated to push the connecting plates 302 until the two... The positioning plates 308 position the packaging bag on both sides. When the positioning plates 308 touch the outside of the packaging bag, they push the sliding sleeve 305 on the outside of the sliding rod 303 under the connection of the transmission rod 306. Then, the sliding sleeve 305 pushes the spring 304 to deform under pressure, so that the two sets of positioning plates 308 will not clamp the packaging bag rigidly, avoiding damage to the spring rolls inside the packaging bag, thereby improving the inspection quality. The packaging bag is positioned and transported into the X-ray inspection machine 2 by the two sets of positioning plates 308 on the conveyor frame 1 for inspection. When the packaging bag collides with the lead curtain on the front of the X-ray inspection machine 2, its rear end is still located between the two sets of positioning plates 308, so that it enters the X-ray inspection machine 2 stably without displacement, thereby allowing the X-ray inspection machine 2 to perform normal inspection and improving the inspection efficiency.

[0030] Furthermore, protective covers 309 are fixedly installed at both ends of the conveyor frame 1 and on the outside of the connecting plate 302. Both ends of the slide rod 303 are fixedly connected to the connecting plate 302 through connecting feet 310. When some components of the positioning mechanism 3 are not working, the slide rod 303 is retracted into the inside of the protective cover 309 for protection. The slide rod 303 is convenient to install and disassemble through the connecting feet 310.

[0031] Then, a guide bevel 311 is fixedly connected to the front end of the positioning plate 308. Multiple sets of rotating shafts 312 are rotatably connected to the side of the positioning plate 308 away from the connector 307. When the packaging bag is placed on the conveyor frame 1, the guide bevel 311 facilitates the introduction of the packaging bag between the two sets of positioning plates 308. The rotating shafts 312 on the two sets of positioning plates 308 assist in the conveying of the packaging bag by rolling, so that while positioning the two sides of the packaging bag, it can be stably conveyed into the X-ray inspection machine 2 for inspection.

[0032] Furthermore, the height limiting mechanism 4 includes a first support frame 401 and a second support frame 402 fixedly installed at the left and right ends of the conveyor frame 1. Adjusting seats 403 are slidably connected to the inner sides of both the first support frame 401 and the second support frame 402. A height limiting plate 404 is fixedly installed between the two sets of adjusting seats 403. A threaded rod 405 is rotatably connected to the inner side of the first support frame 401. The interior of the adjusting seat 403 is threadedly connected to the threaded rod 405 via a threaded sleeve 406, and the threaded sleeve 406 is rotatably connected to the adjusting seat 403. A motor 407 is fixedly installed on the top of the first support frame 401. Furthermore, the drive end of the motor 407 is fixedly connected to the top of the threaded rod 405. While positioning the two sides of the packaging bag using two sets of positioning plates 308, the motor 407 is started to drive the threaded rod 405 to rotate. Under the connection of the threaded sleeve 406, the adjusting seat 403 is driven to slide inside the first support frame 401 and the second support frame 402, thereby adjusting the height of the height limit plate 404. When packaging bags are stacked on the conveyor frame 1, it blocks them and prevents the stacked packaging bags from entering the interior of the conveyor frame 1 for testing at the same time, thus ensuring the testing quality.

[0033] Secondly, both sides of the first support frame 401 and the second support frame 402 are provided with sliding grooves 408, and both ends of the adjusting seat 403 are slidably connected to the sliding grooves 408, so that the adjusting seat 403 can slide stably under the connection of the sliding grooves 408.

[0034] Secondly, a housing 501 is fixedly installed on the left end of the discharge hood 5. A second cylinder 502 is fixedly installed inside the housing 501. A pusher plate 503 is fixedly installed on the drive end of the second cylinder 502. A waste bin 504 is fixedly installed on the right end of the discharge hood 5. The waste bin 504 is connected to the inside of the discharge hood 5. After the packaging bags are inspected inside the X-ray inspection machine 2, they are discharged from the rear end of the discharge hood 5. When a defective product is detected, the second cylinder 502 is activated to push the pusher plate 503 for sorting. The defective products are pushed into the waste bin 504 for collection and processing, while qualified products are discharged normally, which further improves the inspection efficiency.

[0035] In this embodiment, the specific implementation scenario is as follows: When inspecting spring roll filling, after placing the packaging bag at the front end of the conveyor frame 1, the first cylinder 301 is activated to push the connecting plate 302 until the two sets of positioning plates 308 position the two sides of the packaging bag respectively. At the same time, after the positioning plates 308 touch the outer side of the packaging bag, they can push the sliding sleeve 305 on the outer side of the sliding rod 303 under the connection of the transmission rod 306. Subsequently, the sliding sleeve 305 pushes the spring 304 to be deformed by pressure, so that the two sets of positioning plates 308 will not rigidly clamp the packaging bag, avoiding damage to the spring rolls inside the packaging bag, thereby improving the inspection quality. The packaging bag is positioned and conveyed into the X-ray inspection machine 2 by the two sets of positioning plates 308 on the conveyor frame 1 for inspection, so that when the packaging bag collides with the lead curtain on the front of the X-ray inspection machine 2, its rear end is still located at the two sets of positioning plates 308. The positioning plates 308 are positioned to ensure stable entry into the X-ray inspection machine 2 without displacement, thus enabling the X-ray inspection machine 2 to perform normal inspections and improving inspection efficiency. When packaging bags are stacked on the conveyor frame 1, they are blocked. The height limiting mechanism 4 prevents stacked packaging bags from entering the conveyor frame 1 for inspection simultaneously, thus avoiding interference. After being inspected inside the X-ray inspection machine 2, the packaging bags are discharged uniformly from the rear end of the discharge hood 5. When defective products are detected, the second cylinder 502 is activated to push the pusher plate 503 for sorting, pushing the defective products into the waste bin 504 for collection and processing, while qualified products are discharged normally. The entire operation process is simple and convenient. Compared with existing spring roll filling foreign object detection equipment, this utility model improves the detection quality and efficiency of spring roll filling foreign object detection equipment through design.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
