[0026] Figures 1 to 3An embodiment of a length-adjustable conveyor belt device of the present invention is shown. The length-adjustable conveyor belt device of this embodiment includes a support frame 1, a fixed mounting seat 2, a movable mounting seat 3, a driving wheel 4, a driven wheel 5, a conveyor belt 6, a tensioning wheel mechanism 7, a length adjustment mechanism 8 and a driving mechanism 10 for driving the driving wheel 4 to rotate. The driving wheel 4 is arranged on the fixed mounting seat 2, the driven wheel 5 is arranged on the movable mounting seat 3, the fixed mounting seat 2 is fixed on the support frame 1, and the movable mounting seat 3 is slidably arranged on the support frame 1. The length adjustment mechanism 8 is used to drive the movable mounting seat 3 to move so that the driven wheel 5 approaches or moves away from the driving wheel 4. The conveyor belt 6 is wound around the driving wheel 4, the driven wheel 5 and the tensioning wheel mechanism 7. The tensioning wheel mechanism 7 is used to adjust the tension of the conveyor belt 6.

[0027] This length-adjustable conveyor belt device uses a length adjustment mechanism 8 to drive a movable mounting base 3 to move the driven pulley 5 toward or away from the driving pulley 4, thereby adjusting the conveying length between the driving pulley 4 and the driven pulley 5. Simultaneously, a tensioning pulley mechanism 7 controls the tensioning force based on the length adjustment, ensuring that the tension of the conveyor belt 6 is always at an appropriate level for conveying. The adjustable conveying length of the conveyor belt 6 in this conveyor belt device can adapt to changes in the distance between production equipment and the conveying location, providing strong adaptability. Furthermore, length adjustment can eliminate processing errors and facilitate installation of the conveyor belt device.

[0028] In this embodiment, the length adjustment mechanism 8 includes a screw 81, a sliding seat 82, and a rotary motor 83 for rotating the screw 81. The screw 81 is rotatably mounted on the support frame 1. The sliding seat 82 is threadedly connected to the screw 81 and slidably mounted on the support frame 1. The movable mounting seat 3 is connected to the support frame 1. The rotary motor 83 drives the screw 81 to rotate, causing the sliding seat 82 to slide on the support frame 1, thereby driving the movable mounting seat 3 to extend forward, thereby moving the driven wheel 5 away from the driving wheel 4, thereby lengthening the conveying length of the conveyor belt 6; conversely, shortening the conveying length.

[0029] In this embodiment, a screw rod mounting seat 11 is provided on the support frame 1, and the screw rod 81 is provided on the screw rod mounting seat 11, so as to facilitate the installation of the screw rod 81.

[0030] In this embodiment, the rotary motor 83 and the screw rod 81 are connected via a coupling 84. The coupling 84 serves to connect the transmission.

[0031] In this embodiment, the tensioning wheel mechanism 7 includes a first transition wheel 71, a second transition wheel 72, a tensioning wheel 73, and an adjustment assembly 74, which are arranged on the support frame 1. The first transition wheel 71 and the second transition wheel 72 are respectively located below the driving wheel 4 and the driven wheel 5. The tensioning wheel 73 is located between the driven wheel 5 and the second transition wheel 72. The conveyor belt 6 is wound around the driving wheel 4, the driven wheel 5, the second transition wheel 72, the tensioning wheel 73, and the first transition wheel 71. The tensioning wheel 73 is located outside the conveyor belt 6. The adjustment assembly 74 is used to drive the tensioning wheel 73 to move on the support frame 1. When the driven wheel 5 moves away from the driving wheel 4, the conveying length of the conveyor belt 6 is increased, the adjustment assembly 74 should drive the tensioning wheel 73 to move toward the outside of the conveyor belt 6 to reduce the tension. When the driven wheel 5 moves closer to the driving wheel 4, the conveying length of the conveyor belt 6 is shortened, the adjustment assembly 74 should drive the tensioning wheel 73 to move toward the inside of the conveyor belt 6 to increase the tension.

[0032] In this embodiment, the adjustment assembly 74 includes an adjustment screw 741, an adjustment nut 742, and a mounting sleeve 743. The mounting sleeve 743 is mounted on the support frame 1, and the adjustment nut 742 is mounted on the tensioning pulley 73. The adjustment screw 741 is slidably connected to the mounting sleeve 743. The adjustment screw 741 passes through the mounting sleeve 743 and is threadedly connected to the adjustment nut 742. By screwing the adjustment screw 741, the tensioning pulley 73 can be driven to move, resulting in a simple structure and convenient adjustment.

[0033] In this embodiment, the length-adjustable conveyor belt device further includes a guide assembly 9, which is used to provide guidance for the movement of the movable mounting seat 3. The guide assembly 9 ensures that the moving trajectory of the movable mounting seat 3 is stable, that is, the stability of the conveying is ensured.

[0034] In this embodiment, the guide assembly 9 includes a guide rod 91 and a guide sleeve 92. The guide rod 91 is provided on the fixed mounting seat 2, and the guide sleeve 92 is provided on the movable mounting seat 3. The guide sleeve 92 is sleeved on the guide rod 91 and can slide relative to the guide rod 91. When the movable mounting seat 3 moves, the guide sleeve 92 slides on the guide rod 91 to provide guidance.

[0035] In this embodiment, a linear bearing 93 is provided between the guide sleeve 92 and the guide rod 91. The linear bearing 93 converts the sliding friction between the guide sleeve 92 and the guide rod 91 into rolling friction, thereby reducing the friction force and improving the smoothness of the movement of the fixed mounting seat 2.

[0036] In this embodiment, protective cover plates 12 are detachably connected to both sides of the support frame 1 to protect the conveyor belt device.

[0037] Although the present invention has been disclosed above with reference to preferred embodiments, this is not intended to limit the present invention. Any person skilled in the art can, without departing from the scope of the present invention, utilize the technical content disclosed above to make many possible changes and modifications to the present invention, or modify it into equivalent embodiments with equivalent variations. Therefore, any simple modifications, equivalent variations, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the scope of protection of the present invention.
