[0019] See Figure 1 and Figure 4As shown, this application proposes a conveying device with adjustable spacing, including a base 1 and a fixed conveying plate 5 installed on the base 1, and further including: a movable conveying plate 6, which is movably disposed on the base 1; a drive screw 13, which is rotatably disposed on the fixed conveying plate 5; a nut block 16, which is movably disposed on the base 1, connected to the movable conveying plate 6, and screwed to the drive screw 13; and a conveying structure, on both the fixed conveying plate 5 and the movable conveying plate 6.

[0020] The base 1 is the structural foundation of an adjustable-pitch conveying device, and all other structures of the adjustable-pitch conveying device are directly or indirectly connected to the base 1. The fixed conveying plate 5 supports one side of the chip board, and the movable conveying plate 6 supports the other side of the chip board. The conveying structure allows the chip board to move on the fixed conveying plate 5 and the movable conveying plate 6, completing the chip board conveying action.

[0021] Among them, the drive screw 13 and the nut block 16 are the core structures of a conveying device with adjustable spacing. When the chip board is not placed on the fixed conveying plate 5 and the moving conveying plate 6, the drive screw 13 is rotated to drive the nut block 16 to move, thereby driving the moving conveying plate 6 to move on the base 1 and adjusting the distance between the moving conveying plate 6 and the fixed conveying plate 5.

[0022] In this embodiment, the nut block 16 is connected to the bottom of the movable conveyor plate 6 by screws, and the movable conveyor plate 6 is movably mounted on the base 1 by the nut block 16.

[0023] Specifically, the fixed conveyor plate 5 supports one side of the chip board, and the movable conveyor plate 6 supports the other side. The conveying structure allows the chip board to move on the fixed conveyor plate 5 and the movable conveyor plate 6, completing the chip board conveying action. In this application, the distance between the movable conveyor plate 6 and the fixed conveyor plate 5 can be adjusted by rotating the drive screw 13, so that an adjustable-pitch conveying device can adapt to chip boards of different specifications, improving the practicality of the adjustable-pitch conveying device.

[0024] See Figure 1 , Figure 2 and Figure 3As shown, in some embodiments, the conveying structure includes: a drive wheel 25, rotatably mounted on the fixed conveyor plate 5 and the movable conveyor plate 6, the drive wheel 25 being used to introduce power; a pair of first driven wheels 29, rotatably mounted on the fixed conveyor plate 5 and the movable conveyor plate 6; the first driven wheels 29 are used to adjust the power transmission of the conveying component and adjust the shape of the conveying component so that the conveying component can better support the chip board. The conveying component is wound around the drive wheel 25 and the pair of first driven wheels 29; the conveying component can be any of a conveyor belt 26 or a conveyor chain. A rotary power source 11 is connected to the drive wheel 25. The rotary power source 11 is a motor, and its output end is connected to an output shaft 24 via a coupling. The output shaft 24 is connected to the drive wheel 25 on the fixed conveyor plate 5 and the movable conveyor plate 6 to drive the drive wheel 25 to rotate, thereby driving the conveying component to rotate, ultimately achieving the purpose of moving the chip board.

[0025] In this embodiment, the fixed conveyor plate 5 and the movable conveyor plate 6 are rotatably equipped with a pair of second driven wheels 23 and a pair of third driven wheels 28. The second driven wheels 23 and the third driven wheels 28 are used to tension the conveyor and distribute the tension force, which helps to improve the service life of the conveyor, the first driven wheel 29, the second driven wheel 23 and the third driven wheel 28.

A movable bearing support is disposed on the movable conveying plate 6 and movably disposed on the base 1; the drive wheel 25 is rotatably disposed on the movable bearing support via the movable bearing support. The movable bearing support is fixed to the movable conveying plate 6 by screws. An end bearing support 12 is also disposed on the output shaft 24 and is fixed to the base 1.

[0027] See Figure 1 and Figure 4As shown, in some embodiments, it further includes: a first fixed connection end 18, one end of the drive screw 13 being rotatably disposed on the first fixed connection end 18; a second fixed connection end 14, the other end of the drive screw 13 being rotatably disposed on the second fixed connection end 14; both the first fixed connection end 18 and the second fixed connection end are detachably connected to the base 1 by screws. A guide post 15 is disposed between the first fixed connection end 18 and the second fixed connection end 14; the guide post 15 is used to guide the nut block 16 17. A guide sleeve 17 is disposed on the nut block 16, adapted to the guide post 15. The cooperation between the guide sleeve 17 and the guide post 15 restricts the movement direction of the nut block 16 and prevents the drive screw 13 from being overloaded.

[0028] In this embodiment, the first fixed connection end 18 and the second fixed connection end 14 are disposed on one side of the rotary power source 11. It also includes a third fixed connection end 4 and a fourth fixed connection end 10, both fixed to the base 1 and located on the other side of the rotary power source 11.
