DETAILED DESCRIPTION
[0023] The technical solutions in the embodiments of the present utility model will be described clearly and completely below in combination with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all the embodiments.
[0024] Embodiment one:
[0025] In combination Figs. 1-3 The core component of the finished carton compression strength detection device shown in the figure is the conveyor 1, which undertakes the task of transporting finished cartons and making them pass through each key detection link in turn. The compression detection machine 2 is provided at the middle side wall position of the conveyor 1, and is the key detection unit of the entire device, which is used to apply pressure to the carton to detect its compression strength. A position adjusting mechanism 3 is arranged at one end of the conveyor 1, which is crucial to ensure that the carton is in the correct position before entering the compression detection machine 2.
[0026] Specifically, the position adjusting mechanism 3 includes a position adjusting frame 301, which serves as the basic support structure of the entire position adjusting mechanism 3 and provides a stable platform for the installation and operation of other components. Two groups of basic bottom pieces 302 are provided on the position adjusting frame 301 in a relative and symmetrical manner, which provide installation reference for the moving parts of the entire position adjusting mechanism 3. Position adjusting guide rails 303 are installed at both ends of the two groups of basic bottom pieces 302, and position adjusting sliders 304 are respectively provided on the position adjusting guide rails 303. The position adjusting sliders 304 and the position adjusting guide rails 303 are precisely matched and adjusted, so that the position adjusting sliders 304 can smoothly slide along the position adjusting guide rails 303. Two groups of position adjusting sliders 304 located at the same end are connected by a centering bottom plate 305. An obstacle avoidance rod 306 is installed at the end of the centering bottom plate 305. The function of the obstacle avoidance rod 306 is to avoid unnecessary collision with other components during the centering process, thereby protecting the equipment and ensuring the smooth progress of the centering process. A centering push plate 307 is further provided on the obstacle avoidance rod 306. The centering push plate 307 directly contacts and pushes the carton for position adjustment. The surface of the centering push plate 307 that contacts the carton is specially treated to ensure that it does not damage the surface of the carton during the pushing process. A synchronous fixing bottom plate 308 is provided between the two groups of basic bottom pieces 302. The synchronous fixing bottom plate 308 provides a rotating support point for a synchronous follow-up plate 309. Linkage rods 3010 are rotatably provided between the two ends of the synchronous follow-up plate 309 and the adjacent centering bottom plates 305. The function of the linkage rods 3010 is to convert the rotating motion of the synchronous follow-up plate 309 into the linear motion of the centering bottom plates 305, thereby realizing the synchronous motion of the two centering bottom plates 305 and ensuring the centering effect on the carton. A position adjusting cylinder 3011 is provided on the position adjusting frame 301. The position adjusting cylinder 3011 serves as the power source of the entire position adjusting mechanism 3. Its telescopic rod is fixedly connected with the side wall of one of the centering bottom plates 305. When the position adjusting cylinder 3011 works, the telescopic motion of its telescopic rod can accurately control the position of the centering bottom plate 305, thereby driving the centering push plate 307 to adjust the position of the carton.
[0027] A defective product separation mechanism 4 is arranged above the other end of the conveyor 1 relative to the position adjustment mechanism 3, and is used to separate the cartons determined as unqualified after being detected by the compression resistance detection mechanism 2 from the conveyor 1. A defective product table 5 is arranged on the side wall of the conveyor 1 at the defective product separation mechanism 4, and is used to receive the defective product cartons separated by the defective product separation mechanism 4, so as to subsequently concentrate the defective products for processing.
[0028] The position adjustment guide rail 303 in the embodiment has a T-shaped cross section. The position adjustment sliding block 304, as a key component cooperating with the position adjustment guide rail 303, has a T-shaped sliding groove accurately formed thereon. The cooperation tolerance between the T-shaped sliding groove and the T-shaped guide rail is strictly controlled, so that the close fit degree is ensured, and the movement is not blocked due to being too tight. The position adjustment sliding block 304 can stably slide on the position adjustment guide rail 303, and provides a solid and reliable foundation for the accurate position adjustment of the centering bottom plate 305 and other components, and effectively guarantees the accuracy and stability of the entire position adjustment mechanism 3.
[0029] In the embodiment, a layer of rubber buffer pad is arranged on the side of the centering push plate 307 close to the carton. The rubber buffer pad is made of high-elastic and wear-resistant high-quality rubber material. When the centering push plate 307 is operated to push the carton, the rubber buffer pad can effectively play a buffering role, so as to avoid rigid collision between the centering push plate 307 and the carton, thereby preventing the carton surface from being scratched and depressed due to uneven stress, and maximizing the protection of the integrity and appearance quality of the carton. In order to further improve the stability and reliability of the centering push plate 307 when pushing the carton, anti-skid lines are arranged on the surface of the rubber buffer pad, so as to increase the friction force between the rubber buffer pad and the surface of the carton.
[0030] In the embodiment, a bearing is arranged at the rotating connection between the synchronous follow-up plate 309 and the synchronous fixed bottom plate 308, so as to ensure that the synchronous follow-up plate 309 rotates stably, smoothly and accurately on the synchronous fixed bottom plate 308. Pin shafts are arranged at the rotating connections of the linkage rod 3010, the synchronous follow-up plate 309 and the centering bottom plate 305, and bushings are sleeved on the pin shafts. The bushings further reduce the friction coefficient of the connection parts of the pin shafts, the synchronous follow-up plate 309 and the centering bottom plate 305, so as to ensure the stability and reliability of the linkage rod 3010 during the transmission of movement.
[0031] The defective product separation mechanism 4 in this embodiment is an important component for sorting defective products in the finished carton compression strength detection device. Its core is the defective product separation body 401, which provides a solid and reliable operation framework for the internal components. Inside the defective product separation body 401, two sets of bearing seats 402 are arranged opposite each other. A threaded rod 403 rotates between the two sets of bearing seats 402. Next to one of the bearing seats 402, a drive motor 404 is installed to drive the rotation of the threaded rod 403. The drive motor 404 has a frequency converter that can be flexibly controlled to adjust to different production scenarios, different carton specifications, and different conveying speeds, etc. to achieve the best defective product separation effect. The drive motor 404 is connected to the threaded rod 403 through a high-precision coupling. The coupling effectively avoids transmission errors and vibration problems caused by connection deviations when transmitting power, ensuring the efficiency and stability of power transmission. A ball nut seat 405 is installed on the threaded rod 403. Separation rails 406 are symmetrically installed on the upper surface of the defective product separation body 401. Separation sliders 407 are precisely fitted on the separation rails 406. A separation plate 408 is firmly fixed between the separation sliders 407 and the ball nut seat 405, accurately and efficiently separating the detected defective products from the conveyor 1 to the defective product table 5.
[0032] The cooperation structure of the separation rails 406 and the separation sliders 407 in this embodiment is highly consistent with the cooperation structure of the position adjustment rails 303 and the position adjustment sliders 304 in terms of design concept and actual structure. Through this carefully designed and highly consistent cooperation structure, the separation rails 406 and the separation sliders 407 can accurately realize the linear motion of the separation plate 408 in the defective product separation mechanism 4, ensuring that the separation operation of the defective products is efficient and stable.
[0033] The separation plate 408 in this embodiment undertakes the key pushing task in the defective product separation mechanism. To ensure its stability and safety during operation, anti-collision pieces 409 are carefully arranged on the sidewalls of both ends of the separation plate 408. When the separation plate 408 moves quickly on the separation rails 406 to perform the defective product separation operation, it may inevitably collide with surrounding equipment or structures due to various unexpected factors. At this moment, the anti-collision pieces 409 at both ends play a key role. In the instant of collision, the anti-collision pieces 409 can quickly elastically deform, converting the huge impact force into their own elastic potential energy, greatly reducing the risk of damage to the separation plate 408 and surrounding equipment caused by the collision. This not only protects the separation plate 408 from being deformed or damaged by collision, prolonging its service life, but also avoids equipment failures caused by collisions, ensuring the continuous and stable operation of the entire defective product separation mechanism 4 and the smooth development of the finished carton compression strength detection work.
