Description

Technical Field

[0001] This utility model belongs to the field of double-speed chain technology, specifically a double-speed chain for conveying packaging boxes. Background Technology

[0002] In modern electronics manufacturing workshops, a large number of small and sophisticated electronic product packaging boxes need to be moved quickly and accurately between different production processes. A high-speed conveyor belt for transporting packaging boxes can play a significant role. With its stable conveying capacity, it can smoothly transport packaging boxes containing electronic products from one process to the next, such as from the component assembly area to the testing area, effectively meeting the needs of efficient electronic product production.

[0003] However, the following problems were found in the implementation of the relevant technologies: In existing packaging box conveying technologies, on the one hand, traditional conveying mechanisms often suffer from unstable operation and jamming during the conveying process due to structural design defects when conveying the moving platform and packaging conveyor tray. This prevents the conveyor chain from operating smoothly, affecting not only conveying efficiency but also potentially damaging the items inside the packaging boxes due to uneven conveying. On the other hand, due to the significant differences in the size and shape of different packaging boxes, traditional limiting devices are difficult to adjust flexibly to adapt to diverse limiting requirements. Furthermore, the installation of the limiting devices and the moving platform is not stable enough, and they are prone to loosening and displacement during the conveying process. Consequently, they cannot effectively limit the packaging boxes, causing them to slip or shift, affecting the normal conveying process. Utility Model Content

[0017] 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.

[0018] like Figures 1 to 4As shown, this utility model provides a high-speed conveyor for transporting packaging boxes, including a base frame 1. Two high-speed conveyor mechanisms 2 are provided on the inner side of the base frame 1. Multiple moving platforms 4 are slidably provided on the upper surface of one of the high-speed conveyor mechanisms 2. Packaging conveying trays 5 are provided on the upper surface of the moving platforms 4. Two symmetrically distributed limiting mechanisms 3 are fixedly provided on the upper surface of the moving platforms 4. The high-speed conveyor mechanism 2 includes two sliding frames 20. One side of the sliding frame 20 is fixedly connected to the inner wall of one side of the base frame 1. The two ends of the two sliding frames 20 are respectively provided with a transmission frame 21. A transmission rod 25 is rotatably provided on the inner side of the transmission frame 21. Two drive wheels 22 are fixedly provided on the outer side of the transmission rod 25. A conveyor chain 27 is meshed with the outer side of the drive wheels 22. The conveyor chain 27 slides and fits against the inner side of the sliding frame 20. A motor 23 is fixedly provided on one side of one of the transmission frames 21. The output end of the motor 23 is fixedly connected to one end of one of the transmission rods 25. Two high-speed conveyor mechanisms 2 are set on the inner side of the base frame 1, and the moving platform 4 is placed on the upper surface of one of the high-speed conveyor mechanisms 2. When motor 23 is started, its output drives the transmission rod 25, which is fixedly connected to it, to rotate. The drive wheel 22 on the transmission rod 25 rotates accordingly. Since the drive wheel 22 is engaged with the conveyor chain 27, the conveyor chain 27 begins to operate. Because the conveyor chain 27 slides against the groove 28 on the inner side of the sliding frame 20, and the transmission frames 21 at both ends of the two sliding frames 20 work together through the transmission rod 25 and the drive wheel 22, the conveyor chain 27 can run stably in a cycle. This drives the moving table 4 to slide on the upper surface of the double-speed chain mechanism 2, realizing the conveying of the packaging conveyor tray 5 and the packaging boxes on it. When loading is required, the loading guide wheel 26 on one side of the transmission frame 21 can guide the packaging boxes to be accurately placed on the packaging conveyor tray 5.

[0019] Specifically, the limiting mechanism 3 includes a base 30, the lower surface of which is fixedly connected to the upper surface of the moving platform 4. A bogie 32 is rotatably mounted on the inner side of the base 30. An adjusting screw 34 is slidably inserted into one end of the bogie 32. A limiting pad 33 is fixedly mounted on the lower end of the adjusting screw 34. Two adjusting nuts 36 are threaded onto the outer side of the adjusting screw 34. A rotating frame 39 is rotatably mounted on the inner side of the base 30. A connecting frame 37 is rotatably mounted on the inner side of the rotating frame 39. One end of the connecting frame 37 is rotatably connected to the middle of the bogie 32. A pull rod 38 is fixedly mounted on the upper surface of the rotating frame 39, which securely fixes the base 30 of the limiting mechanism 3 to the upper surface of the moving platform 4 through multiple fixing holes 31 on its lower surface. According to the size and shape of the packaging box, pulling the pull rod 38 on the upper surface of the rotating frame 39 causes the rotating frame 39 to rotate inside the base 30, simultaneously driving the connecting frame 37, which is rotatably connected to the inner side, to move. The connecting frame 37, in turn, drives the bogie 32, which is rotatably connected to it, to rotate inside the base 30. An adjusting screw 34 is slidably inserted into the insertion hole 35 at one end of the bogie 32. By rotating the two adjusting nuts 36 threaded on the outside of the adjusting screw 34, the height of the lower end limiting pad 33 of the adjusting screw 34 can be adjusted so that the limiting pad 33 contacts the packaging box, thereby achieving flexible limiting of different packaging boxes. The limiting pad 33 is a rubber pad, which can prevent scratching the packaging box while limiting.

[0020] Furthermore, one end of one of the sliding frames 20 is fixed to an assembly frame 24, which is fixedly engaged with the motor 23 on one side. This design provides stable support and a fixed position for the motor 23, ensuring that the motor 23 will not be displaced due to vibration or other reasons during operation, thereby ensuring the stable transmission of the power output of the motor 23 and making the double-speed chain mechanism 2 run more smoothly and reliably.

[0021] Furthermore, the feeding guide wheel 26 fixed on one side of the transmission frame 21 can guide the packaging box when it needs to be placed on the packaging conveyor tray 5 during the conveying process, so that the packaging box can be accurately and smoothly placed in the designated position, avoiding the packaging box from shifting or colliding during the feeding process, thus improving the accuracy and efficiency of feeding.

[0022] It is worth noting that a groove 28 is provided on one side of the sliding frame 20, and the inner side of the groove 28 slides in contact with the conveyor chain 27. The groove 28 provides a dedicated running track for the conveyor chain 27, which can limit the running direction of the conveyor chain 27 and prevent problems such as deviation or derailment during operation, thus ensuring the stability and smoothness of the operation of the conveyor chain 27, and thus ensuring the normal operation of the entire speed-multiplying chain mechanism 2.

[0023] It is worth noting that multiple fixing holes 31 are provided on the lower surface of the base 30, through which the limiting mechanism 3 can be securely fixed to the moving platform 4. During the process of conveying the packaging box, the moving platform 4 will move continuously. The secure fixing method can ensure that the limiting mechanism 3 will not loosen or shift due to the movement of the moving platform 4, thereby ensuring that the limiting effect of the limiting mechanism 3 on the packaging box is always stable and reliable.

[0024] It is worth mentioning that the bogie 32 has a socket 35 at one end, which slides and engages with the adjusting screw 34. The socket 35 provides a stable sliding space for the adjusting screw 34, allowing it to move flexibly up and down on the bogie 32. This facilitates adjusting the height of the limiting pad 33 by adjusting the adjusting nut 36 on the outside of the adjusting screw 34, thus adapting to the limiting requirements of packaging boxes of different heights and improving the versatility and flexibility of the limiting mechanism 3.

[0025] It is worth emphasizing that the limiting pad 33 is made of rubber, which has good elasticity and softness. When the limiting mechanism 3 limits the packaging box, the rubber limiting pad 33 can avoid rigid collision with the packaging box, thereby preventing scratches and damage to the packaging box and its contents. At the same time, the rubber pad can also provide a certain amount of friction, enhance the limiting effect, and ensure the stability of the packaging box during transportation.

[0026] Among them, motor 23 is existing technology and will not be described in detail; at the same time, this utility model also includes a power supply, controller and switch, etc., which are not the main technical points of this patent and will not be described in detail; the "front, back, left and right" perspectives of this device are as follows: Figure 1 The direction shown in the diagram is the reference.

[0027] Working principle: Two double-speed chain mechanisms 2 are set inside the base frame 1, and the moving table 4 is placed on the upper surface of one of the double-speed chain mechanisms 2. The motor 23 is started, and the output end of the motor 23 drives the transmission rod 25 fixedly connected to it to rotate, and the drive wheel 22 on the transmission rod 25 rotates accordingly. Since the drive wheel 22 is engaged with the conveyor chain 27, the conveyor chain 27 starts to run. Because the conveyor chain 27 slides against the groove 28 inside the sliding frame 20, and the transmission frames 21 at both ends of the two sliding frames 20 work together through the transmission rod 25 and the drive wheel 22, the conveyor chain 27 can run stably in a cycle, thereby driving the moving table 4 to slide on the upper surface of the double-speed chain mechanism 2, realizing the conveying of the packaging conveyor tray 5 and the packaging boxes on it. When it is necessary to load, the loading guide wheel 26 on one side of the transmission frame 21 can be used to guide the packaging box to be accurately placed on the packaging conveyor tray 5.

[0028] The base 30 of the limiting mechanism 3 is securely fixed to the upper surface of the moving platform 4 through multiple fixing holes 31 on its lower surface. According to the size and shape of the packaging box, the pull rod 38 on the upper surface of the rotating frame 39 is pulled, causing the rotating frame 39 to rotate inside the base 30. Simultaneously, this drives the connecting frame 37, which is rotatably connected to the inner side, to move. The connecting frame 37, in turn, drives the bogie 32, which is rotatably connected to it, to rotate inside the base 30. An adjusting screw 34 is slidably inserted into the insertion hole 35 at one end of the bogie 32. By rotating the two adjusting nuts 36 threaded on the outer side of the adjusting screw 34, the height of the lower limiting pad 33 of the adjusting screw 34 can be adjusted, allowing the limiting pad 33 to contact the packaging box. This achieves flexible limiting for different packaging boxes, and the limiting pad 33 is a rubber pad, which can prevent scratching the packaging box while limiting movement.
