[0020] like Figure 2 In this embodiment, the frame assembly 1 includes a fixed frame 10, two movable plates 11 and several belt trays 12, the fixed frame 10 is provided with a pulley support plate 13, the movable plate 11 is provided with several bearing pulleys 14 that slide with the pulley support plate 13, the movable plate 11 slides with the fixed frame 10 through the several bearing pulleys 14, the other end of the movable plate 11 is connected and cooperated with the telescopic mechanism 4, and several belt trays 12 are respectively limited and cooperated on the fixed frame 10 and the movable plate 11, and the belt element 3 slides with the several belt trays 12. It can be seen that the movable plate 11 supports and limits the bearing pulleys 14 and the belt trays 12, the fixed frame 10 supports and limits the pulley support plate 13 and the belt trays 12, and the pulley support plate 13 supports and guides the bearing pulleys 14. When the driving assembly 40 pushes the movable plate 11 to move, the movable plate 11 slides on the pulley support plate 13 through the bearing pulleys 14, so that the position of the movable plate 11 changes.

[0021] like Figure 1 and Figure 4 In this embodiment, the telescopic mechanism 4 includes a drive assembly 40, a telescopic connecting plate 41, a drawer guide rail assembly 42 and a guide shaft 43. The drive assembly 40, the drawer guide rail assembly 42 and the guide shaft 43 are all limitedly fitted on the fixed frame 10, the telescopic connecting plate 41 is fixedly fitted on the movable plate 11, the movable end of the drive assembly 40 and the movable end of the drawer guide rail assembly 42 are connected and fitted with the telescopic connecting plate 41, and one end of the telescopic connecting plate 41 is slidably fitted on the guide shaft 43.

The drawer guide assembly 42 and the guide shaft 43 both guide the forward and backward movement of the telescopic connecting plate 41, ensuring that the telescopic connecting plate 41 does not swing left and right when moving forward.

[0022] like Figure 2In this embodiment, the movable plate 11 is provided with a sensor that cooperates with the product component. The fixed frame 10 and the movable plate 11 are both provided with a stopper 15 that cooperates with the product component to limit its position. Thus, the movable plate 11 supports and limits the sensor. When the sensor detects that a product component has flowed through the designated position, it sends a signal to prepare the next workstation. The fixed frame 10 and the movable plate 11 support and limit the stopper 15. The stopper 15 guides and aligns the moving product component, ensuring that the product component's edge is parallel to the belt direction when it flows to the end.

[0023] like Figure 3 In this embodiment, the roller assembly 2 includes a speed regulating motor assembly, a tensioning wheel assembly, and a roller assembly. The speed regulating motor assembly is fixed to the fixed frame 10. The output end of the speed regulating motor assembly rotates with the roller assembly. The tensioning wheel assembly and the roller assembly are respectively limited and engaged on the fixed frame 10 and the two movable plates 11. The belt element 3 rotates with the tensioning wheel assembly and the roller assembly in turn. It can be seen that the fixed frame 10 supports and fixes the speed regulating motor assembly, and the speed regulating motor assembly provides a driving force to the roller assembly, so that the roller assembly drives the belt element 3 to rotate, thereby driving the product element to move. The tensioning wheel assembly adjusts the tension of the belt element 3 to ensure that the belt element 3 maintains appropriate tension during the transmission process. At the same time, it can also change the contact angle between the belt element 3 and the pulley, which helps to increase the friction between the belt element 3 and the roller assembly, thereby enhancing the stability and efficiency of the transmission.

[0024] like Figures 1 to 4 In this embodiment, the fixed frame 10 and the movable plate 11 are both composed of a plurality of connected aluminum profiles. This demonstrates that the plurality of aluminum profiles forming the fixed frame 10 and the movable plate 11 offer structural stability, strong plasticity, and wear resistance. These aluminum profiles are capable of withstanding heavy loads and vibrations, ensuring stable operation of the equipment and meeting the design requirements of various complex structures. Furthermore, these aluminum profiles are simple and quick to assemble, requiring no welding, reducing installation difficulty and cost. This assembly method also facilitates subsequent maintenance and replacement.

As can be seen, the driving assembly 40 uses a cylinder, which has the characteristics of large output torque and strong adaptability. While meeting the requirements of use, it can reduce design costs. In addition, the cylinder has a simple structure and is easy to use and maintain.

[0026] like Figure 3 In this embodiment, the speed regulating motor assembly includes a speed regulating motor element 20, two synchronous pulleys 21, and a synchronous belt element 22. The two synchronous pulleys 21 are respectively limitedly engaged with the speed regulating motor element 20 and the roller assembly, and the synchronous belt element 22 is respectively engaged with the two synchronous pulleys 21. It can be seen that the output end of the speed regulating motor element 20 drives the synchronous pulleys 21 limitedly engaged with the speed regulating motor element 20, and the synchronous pulley 21 drives the synchronous pulleys 21 limitedly engaged with the roller assembly through the synchronous belt element 22, thereby transferring the rotational output of the speed regulating motor element 20 to the roller assembly.

[0027] like Figure 3 In this embodiment, the tensioning wheel assembly includes a rear tensioning wheel 23, a telescopic tensioning wheel 24, and a fixed tensioning wheel 25. The rear tensioning wheel 23 is fixedly engaged with the fixed frame 10, and the telescopic tensioning wheel 24 and the fixed tensioning wheel 25 are fixedly engaged with the movable plate 11. The belt element 3 is sequentially rotatably engaged with the rear tensioning wheel 23, the telescopic tensioning wheel 24, and the fixed tensioning wheel 25. It can be seen that the fixed frame 10 supports and limits the rear tensioning wheel 23, the movable plate 11 supports and limits the telescopic tensioning wheel 24 and the fixed tensioning wheel 25, the rear tensioning wheel 23 adjusts the tension and proper tension of the belt element 3 in the rear direction, the fixed tensioning wheel 25 adjusts the tension and proper tension of the belt element 3 in the bottom direction, and the telescopic tensioning wheel 24 adjusts the tension and proper tension of the belt element 3 after being driven by the telescopic mechanism 4.

[0028] like Figure 3 In this embodiment, the roller assembly includes a transmission roller 26, a rear roller 27, and a front roller 28. The transmission roller 26 and the rear roller 27 are fixedly engaged with the fixed frame 10, and the front roller 28 is fixedly engaged with the movable plate 11. The belt element 3 is rotatably engaged with the transmission roller 26, the rear roller 27, and the front roller 28 in sequence. It can be seen that the fixed frame 10 supports and limits the transmission roller 26 and the rear roller 27, the movable plate 11 supports and limits the front roller 28, the rear roller 27 and the front roller 28 support and limit the belt element 3 in the front-to-back direction, and the transmission roller 26 provides driving, support, and limiting functions for the belt element 3.

[0029] In this embodiment, the working principle of the utility model is as follows:

[0030] like Figures 1 to 4 As shown, the telescopic belt line mechanism can normally transport products in both the extended and retracted states. During transportation, the speed regulating motor element 20 is started to rotate the two synchronous pulleys 21 and the synchronous belt element 22, thereby driving the transmission roller 26 to rotate. The belt element 3 respectively passes around the rear tensioning wheel 23, the rear roller 27, the telescopic tensioning wheel 24, the front roller 28, and the fixed tensioning wheel 25, thereby driving the entire belt line to rotate to transport materials. When transporting materials, when the product element flows through the stopper 15, the stopper 15 guides and straightens the product element. When the product element flows to the end, the sensor will send a signal to prompt the next station to take action.

[0031] When the telescopic belt line mechanism is ready to be in the extending action;

[0032] The driving assembly 40 pushes the movable plate 11 and the telescopic connecting plate 41 to extend, and at the same time, drives the telescopic tensioning wheel 24, the front roller 28, and the belt tray 12 to extend forward together. The front end of the belt element 3 is stretched by the telescopic tensioning wheel 24, and the belt element 3 between the front roller 28 and the fixed tensioning wheel 25 in the retracted state is pulled out, and the tensioned state is restored after being extended. At this time, the speed regulating motor 20 is still rotated to drive the belt element 3 to rotate for transportation.

[0033] When the telescopic belt line mechanism is ready to be in a retracting action;

[0034] The driving assembly 40 pushes the movable plate 11 and the telescopic connecting plate 41 to retract, and at the same time, drives the telescopic tensioning wheel 24, the front roller 28, and the belt tray 12 to retract together. The telescopic connecting plate 41 re-tightens the extended belt element 3 to the middle of the front roller 28 and the fixed tensioning wheel 25 to complete the retraction operation. At this time, the speed regulating motor 20 is still rotated to drive the belt element 3 to rotate for transportation.

[0035] Although the embodiments of the present invention are described with practical solutions, they do not limit the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
