Description

Technical Field

[0001] This utility model relates to the field of conveyor belt technology, specifically a conveyor belt for a single-box re-inspection machine with automatic start-stop function. Background Technology

[0002] A single-box re-inspection machine is a device used to inspect the weight of a single box of products. It can accurately measure the weight of a single box of products and determine whether it meets the preset weight standard. Through weight inspection, it can also indirectly determine whether the products in the box are missing parts or instructions. The conveyor belt of the re-inspection machine is an important component used for conveying and bearing weight. It is responsible for carrying and conveying materials to ensure that the materials can pass through the re-inspection machine smoothly and accurately for inspection.

[0003] When using a single-box re-inspection machine, if a conveyor belt is needed for assistance, the conveyor motor is started first, causing the conveyor belt at the top of the conveyor to move. Then, the moving conveyor belt brings the products on its surface closer to the re-inspection machine. At this time, the re-inspection machine detects the weight of the products to determine whether the products meet the weight standards. However, during the use of the single-box re-inspection machine's conveyor belt, it runs continuously regardless of whether there are products passing through it. Opening and closing the conveyor belt requires manual operation by the operator. This results in the conveyor belt running idle when no products are passing through, leading to waste. Furthermore, the conveyor belt transports products through friction between itself and the products. If products are not separated, they are prone to deviating during transport and slipping off the sides of the conveyor belt, thus affecting the use of the re-inspection machine's conveyor belt. Utility Model Content

[0004] The purpose of this invention is to provide a conveyor belt for a single-box re-inspection machine with automatic start-stop function, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a conveyor belt for a single-box re-inspection machine with automatic start-stop function, comprising a conveyor, a conveyor belt, and a photoelectric sensor.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-5This utility model provides a technical solution: a conveyor belt for a single-box re-inspection machine with automatic start-stop function, including a conveyor 1, a conveyor belt 2, and a photoelectric sensor 4. The top of the conveyor 1 is connected to the conveyor belt 2 via a conveyor roller, and a support platform 3 is connected to one side of the outer wall of the conveyor 1. The photoelectric sensor 4 is installed on the top of the support platform 3. A limit mechanism 5 is provided on the outer wall of the conveyor 1, and the limit mechanism 5 includes a protective box 501, a servo motor 502, a threaded column 503, a guide seat 504, a slide 505, a track 506, a transmission rod 507, and a base 508. The conveyor 1 consists of a fixed column 509, a limiting plate 510, a snap-fit ​​seat 511, a threaded rod 512, and a rubber disc 513. Protective boxes 501 are connected to both sides of the bottom of the conveyor 1. A servo motor 502 is installed at the bottom of the outer wall of the protective box 501, and a threaded column 503 is connected to the output end of the servo motor 502. A guide seat 504 is threadedly connected to the middle of the outer wall of the threaded column 503, and a transmission rod 507 is rotatably connected to the top of the guide seat 504. The top of the transmission rod 507 is rotatably connected to the limiting plate 510. The base 508 has the limiting plate 510 connected to its top center. A slide block 505 is welded to the bottom of the outer wall of the base 504, and a track 506 is slidably connected inside the slide block 505. The support platform 3 has a "Z"-shaped structure design, and the guide seats 504 are evenly distributed. The slide block 505 has a "C"-shaped structure design. The bottom of the outer wall of the track 506 is welded to the inner wall of the protective box 501. The side of the threaded column 503 away from the servo motor 502 is connected to both sides of the inner wall of the protective box 501 through a bearing seat. The top of the protective box 501 has an outlet, and the limiting plate 510 extends into it. Fixed columns 5 are slidably connected to both sides of the outer wall of the base 508. 09, and the outer wall of the fixed column 509 is welded to the inner wall of the protective box 501. The limiting plate 510 is connected to the snap-fit ​​seat 511. The top of the snap-fit ​​seat 511 is threadedly connected to the threaded rod 512, and the outer wall of the threaded rod 512 is connected to the rubber disc 513. The limiting plate 510 has a snap-fit ​​cavity, and the snap-fit ​​seat 511 extends into it. The snap-fit ​​seat 511 has a "T" shaped structure design. The limiting plates 510 are evenly distributed. The support platform 3 is symmetrically distributed about the vertical center line of the conveyor belt 2. The protective box 501 has a movable cavity.

[0020] In practice, during the use of the conveyor belt of the single-box re-inspection machine with automatic start and stop function, since the conveyor 1 is connected to the sensor 4 through the support platform 3, the sensor 4, in conjunction with the time control circuit, will automatically start the conveyor belt 2 when a product is detected passing by, and automatically stop the conveyor belt 2 when no product passes by, thereby reducing the power loss caused by the idling of the conveyor belt 2.

[0021] To prevent the product from slipping off the conveyor belt 2, the servo motor 502 at the bottom of the protective box 501 is first started. Since the output end of the servo motor 502 is connected to the threaded post 503, starting the servo motor 502 will drive the threaded post 503 to rotate. Then, the rotation of the threaded post 503 will drive the guide seat 504 to move. Because the bottom end of the guide seat 504 is connected to the slide 505, the slide 505 moves along the track 506, thus limiting the movement of the guide seat 504 and ensuring its smooth movement. Furthermore, because the guide seat 504 and the transmission rod 507 are rotatably connected, the movement of the guide seat 504 will drive the transmission rod... When 507 rotates, the angle between the guide seat 504 and the transmission rod 507 changes, which in turn generates a thrust on the base 508, causing the base 508 to move upward along the fixed column 509. Since the base 508 is connected to the limiting plate 510, the movement of the base 508 will drive the limiting plate 510 to move together until the limiting plate 510 moves to the designated height, thereby covering both sides of the conveyor 1 to prevent products from falling off both sides of the conveyor belt 2 and affecting work efficiency. Furthermore, the limiting plate 510 can be moved down and stored inside the protective box 501 to prevent the limiting plate 510 from obstructing the workers from cleaning the conveyor belt 2.

[0022] To prevent the product from shifting significantly on the conveyor belt 2, first insert the locking seat 511 into the limiting plate 510. At this time, the limiting plate 510 and the locking seat 511 are engaged. Then, rotate the threaded rod 512 to move the rubber discs 513, causing them to move closer to each other. This makes the distance between the rubber discs 513 correspond to the volume of the product. During the transport of the product on the conveyor belt 2, the product is confined between the rubber discs 513, preventing significant shifts. The rubber discs 513 can be removed simply by moving the locking seat 511 upwards, making it convenient and flexible to use. This provides a convenient function for limiting, preventing slippage, and preventing shifting when used on a single-box re-inspection machine conveyor belt with automatic start / stop function.

[0023] In summary, when using this single-box weighing inspection machine conveyor belt with automatic start-stop function, the conveyor motor is first started, causing the conveyor belt 2 at the top of the conveyor 1 to move. Then, the moving conveyor belt 2 brings the products on its surface closer to the weighing inspection machine. At this time, the weighing inspection machine detects the weight of the products to determine whether the products meet the weight standards. This is existing technology and will not be elaborated on here. The limiting mechanism 5 causes the base 508 to move the limiting plate 510 to a specified height, thereby covering both sides of the conveyor 1 to prevent the products from falling off the sides of the conveyor belt 2 and affecting work efficiency. The rotating threaded rod 512 makes the distance between the rubber discs 513 correspond to the volume of the products, thereby restricting the products between the rubber discs 513 and preventing large-scale deviation of the products during transportation. The contents not described in detail in this description are existing technologies known to those skilled in the art.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
