[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Example 1, such as Figures 1-5As shown, this utility model provides a limiting conveyor device for food packaging bags, including a workbench 1, a conveyor belt 3 on the top of the workbench 1, an L-shaped frame 10 fixedly installed on the top of the workbench 1, a camera 11 fixedly installed on the inner wall of the L-shaped frame 10, an electric telescopic rod 12 fixedly installed on the outer wall of the L-shaped frame 10, the telescopic end of the electric telescopic rod 12 passing through the L-shaped frame 10 and fixedly installed with a U-shaped scraper 13, an opening 7 through the top of the workbench 1, placement grooves 8 on both sides inside the opening 7, an L-shaped groove 14 through the inner wall of the placement groove 8, an L-shaped slide plate 15 slidably installed inside the L-shaped groove 14, a first motor 16 fixedly installed on the outer wall of the L-shaped slide plate 15, a gear 17 fixedly installed on the output end of the first motor 16, a rack 18 fixedly installed on the bottom of the workbench 1, the gear 17 meshing with the rack 18, and two collection boxes 9 fixedly installed on one end of the L-shaped slide plate 15.

[0027] The overall effect of Embodiment 1 is as follows: when the camera 11 detects a foreign object on the conveyor belt 3, the operator activates the electric telescopic rod 12. The telescopic end of the electric telescopic rod 12 pushes the U-shaped scraper 13 to move. The U-shaped scraper 13 moves onto the conveyor belt 3 and contacts the foreign object, pushing the foreign object away from the conveyor belt 3 until the foreign object falls into the opening 7 and finally into the collection box 9. When there are too many foreign objects in the collection box 9, the operator moves and activates the first motor 16. The output end of the first motor 16 drives the gear 17 to rotate, causing the gear 17 to move along the rack 18. When the gear 17 moves to the other end of the rack 18, another collection box 9 moves below the opening 7, improving the collection efficiency.

[0028] Example 2, as Figures 1-5 As shown, further, two support plates 19 are symmetrically installed at the bottom of the collection box 9, and a rotating shaft 20 is rotatably installed between the two support plates 19. A baffle 21 is fixedly installed on the outer wall of the rotating shaft 20. When the operator rotates the baffle 21, the baffle 21 rotates along the rotating shaft 20. At this time, foreign objects in the collection box 9 can leave through the gap between the baffle 21 and the collection box 9, and the support plates 19 can prevent foreign objects from leaving from both sides of the baffle 21.

[0029] Furthermore, a U-shaped frame 22 is fixedly installed on the outer wall of the collection box 9, and a spring 23 is fixedly installed on the inner wall of the U-shaped frame 22. An L-shaped partition 24 is fixedly installed on one end of the spring 23. When the worker pulls the L-shaped partition 24, the L-shaped partition 24 moves and no longer contacts the baffle 21. At this time, the spring 23 is compressed.

[0030] Furthermore, a limiting rod 25 is fixedly installed on the outer wall of the L-shaped partition 24. One end of the limiting rod 25 is slidably inserted into the U-shaped frame 22 to limit the L-shaped partition 24 and prevent the L-shaped partition 24 from tilting.

[0031] Furthermore, two U-shaped seats 4 are fixedly installed on the top of the workbench 1. The inner wall of the U-shaped seat 4 is provided with a sliding groove 26. A threaded rod 27 is rotatably installed inside the sliding groove 26. A second motor 28 is fixedly installed on the outer wall of the U-shaped seat 4. The output end of the second motor 28 passes through the U-shaped seat 4 and is fixedly connected to one end of the threaded rod 27. Two sliders 29 are threadedly connected to the outer wall of the threaded rod 27.

[0032] Furthermore, a hydraulic cylinder 30 is fixedly installed at the bottom of the slider 29, and a storage seat 5 is fixedly installed at the bottom of the hydraulic cylinder 30. When the camera 11 detects a foreign object on the conveyor belt 3, the operator starts the hydraulic cylinder 30. The output end of the hydraulic cylinder 30 drives the storage seat 5 to rise, preventing the storage seat 5 from affecting the movement of the U-shaped scraper 13.

[0033] Furthermore, the storage base 5 is equipped with multiple evenly distributed rollers 6 that rotate inside, reducing friction and lowering the resistance to movement of the food packaging bag.

[0034] Furthermore, support frames 2 are fixedly installed at the four corners of the bottom of the workbench 1 to provide support for the workbench 1.

[0035] Furthermore, the inner wall of the L-shaped partition 24 is in contact with the outer wall of the baffle 21. When cleaning is finished, the staff rotates the baffle 21 so that its top is in contact with the bottom of the collection box 9, and then releases the L-shaped partition 24. At this time, the L-shaped partition 24 moves under the elastic force of the spring 23 until the inner wall of the L-shaped partition 24 is in contact with the outer wall of the baffle 21. In this way, the baffle 21 can be fixed and prevented from shaking up and down.

[0036] Furthermore, the threaded rod 27 is provided with two sections of threads with opposite textures. The threaded rod 27 is connected to two sliders 29 respectively through the two sections of threads with opposite textures. When the threaded rod 27 rotates, the two sliders 29 move closer to each other or further away from each other.

[0037] The effect achieved by the entire embodiment 2 is that during cleaning, the staff pulls the L-shaped partition 24, the L-shaped partition 24 moves and no longer contacts the baffle 21. At this time, the spring 23 is compressed. At this time, the staff rotates the baffle 21, the baffle 21 rotates along the drive shaft 20, and the foreign objects in the collection box 9 can leave through the gap between the baffle 21 and the collection box 9, which facilitates the staff to collect them.

[0038] Working principle: When in use, the staff places the food packaging bag on the conveyor belt 3, and then starts the second motor 28. The output end of the second motor 28 drives the threaded rod 27 to rotate, so that the two sliders 29 move closer to each other. Then, the hydraulic cylinder 30 drives the two storage seats 5 to move closer to each other until the rollers 6 on both sides contact the two sides of the food packaging bag. At this time, the food packaging bag can be limited to prevent it from deviating from the direction. When camera 11 detects a foreign object on conveyor belt 3, the operator activates hydraulic cylinder 30. The output end of hydraulic cylinder 30 drives storage seat 5 to rise. At this time, the operator activates electric telescopic rod 12. The telescopic end of electric telescopic rod 12 pushes U-shaped scraper 13 to move. U-shaped scraper 13 moves to conveyor belt 3 and contacts the foreign object, pushing the foreign object away from conveyor belt 3 until the foreign object falls into opening 7 and finally into collection box 9. When there are too many foreign objects in collection box 9, the operator moves and activates first motor 16. The output end of first motor 16 drives gear 17 to rotate, causing gear 17 to move along rack 18. When gear 17 moves to the other end of rack 18, another collection box 9 moves below opening 7, improving collection efficiency. During cleaning, the worker pulls the L-shaped partition 24, causing it to move and no longer contact the baffle 21. At this point, the spring 23 is compressed. The worker then rotates the baffle 21, causing it to rotate along the drive shaft 20. This allows foreign objects in the collection box 9 to leave through the gap between the baffle 21 and the collection box 9, facilitating collection. When cleaning is finished, the worker rotates the baffle 21 so that its top is flush with the bottom of the collection box 9, and then releases the L-shaped partition 24. The L-shaped partition 24 moves under the elastic force of the spring 23 until its inner wall is flush with the outer wall of the baffle 21, thus fixing the baffle 21 in place and preventing it from wobbling.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
