As shown in fig. 1 to 4, the conveying apparatus of the present embodiment includes: the bracket 10, the first transfer mechanism 20, the second transfer mechanism 30, and the stopper 40. The first conveying mechanism 20 is provided on the rack 10 and is used for conveying the member to be conveyed 90. The second transfer mechanism 30 is swingably provided on the bracket 10 downstream of the first transfer mechanism 20. Wherein a first end of the second transfer mechanism 30 is rotatably disposed on the bracket 10 and disposed adjacent to the first transfer mechanism 20, and the second transfer mechanism 30 has a transfer position in which the second end thereof is raised and a stop position in which the second end thereof is lowered when swinging. A stop 40 is provided on the carriage 10 downstream of the second end of the second conveyor 30. Wherein, when the second conveying mechanism 30 is at the conveying position, the upper surfaces of the first conveying mechanism 20, the second conveying mechanism 30 and the stopper 40 are flush. When the second conveying mechanism 30 is at the stop position, the second end of the second conveying mechanism 30 is located below the stop member 40 so that the stop member 40 stops the member to be conveyed 90.

By applying the technical scheme of the embodiment, after the second end of the second conveying mechanism 30 swings below the stop piece 40, due to the height difference between the second end of the second conveying mechanism 30 and the stop piece 40, the side wall of the piece 90 to be conveyed on the second conveying mechanism 30 is abutted against the stop piece 40, so that the conveying of the piece 90 to be conveyed can be stopped, and the situation that a plurality of pieces 90 to be conveyed, which are caused by the fact that the pieces 90 to be conveyed on the conveying belt are more and are close to the inlet of the box sealing device, enter the box sealing device is reduced. Thus, when the conveying speed of the conveying belt is low or there are few pieces to be conveyed 90 on the conveying belt near the entrance of the box sealing device, the second conveying mechanism 30 is brought to the conveying position so that the pieces to be conveyed 90 can enter the box sealing device through the conveying device.

Therefore, the technical scheme of the embodiment effectively solves the problems that a plurality of boxes in the related art enter the box sealing device from the discharging end of the conveying belt, the box sealing device is easy to stop and damage the boxes, normal production order and efficiency are affected, and certain loss is caused to materials.

The "flush setting" in the "flush setting of the upper surfaces of the first conveying mechanism 20, the second conveying mechanism 30, and the stopper 40" may be that the upper surfaces of the first conveying mechanism 20, the second conveying mechanism 30, and the stopper 40 are in the same plane. The "flush setting" may also be such that the difference in height between the upper surfaces of the first conveying mechanism 20, the second conveying mechanism 30, and the stopper 40 is within a preset range, and when the difference in height is within the preset range, it is necessary to enable the conveyance of the member to be conveyed 90 into the box sealing device by the first conveying mechanism 20, the second conveying mechanism 30, and the stopper 40.

In the present embodiment, in order to facilitate the conveyance of the member to be conveyed 90, the stopper 40 is a roller rotatably provided on the bracket 10.

As shown in fig. 1-4, the conveyor further includes a first drive member 70 disposed below the second end of the second conveyor 30. The first driving member 70 drives the second end of the second transfer mechanism 30 to move up and down to switch the second transfer mechanism 30 between the transfer position and the stop position. The arrangement of the first driving member 70 facilitates the swinging of the second conveying mechanism 30 to facilitate the control of the conveying state of the member to be conveyed 90 on the conveying device, and improves the production efficiency.

In an embodiment not shown in the figures, the second transfer mechanism can be controlled to switch between a transfer position and a stop position using manual operation or foot operation.

In this way, the provision of the second driving member and the first driving belt 22 facilitates the rolling of the first roller 21 to improve the conveying efficiency of the first conveying mechanism 20 to the conveying member 90. The second conveying mechanism 30 includes a frame 33, a plurality of second rollers 31 rollably provided on the frame 33, and a plurality of second driving belts 32. Each second driving belt 32 is connected between two adjacent second rollers 31 and drives the two second rollers 31 to synchronously roll. The first end of the frame 33 is rotatably disposed on the bracket 10, and the second end of the frame 33 is liftably disposed. Thus, the plurality of second rollers 31 on the frame 33 can be driven to swing synchronously when the frame 33 swings. The member to be conveyed 90 on the second conveying mechanism 30 can be conveyed from upstream to downstream by the rolling of the second roller 31 so that the member to be conveyed 90 on the second conveying mechanism 30 can pass over the stopper 40 or be in stopping engagement with the stopper 40. The conveyor further comprises a third drive belt 50, the third drive belt 50 being drivingly connected to adjacent first 21 and second 31 drums. The third driving belt 50 is provided so as to drive the second roller 31 to synchronously roll with the first roller 21 so as to make the conveying speed on the conveying device uniform.

The first driving member 70 has a telescopic rod 71 which is telescopically arranged, and the telescopic rod 71 is connected to the connection beam 333. The end of the first side member 331 facing away from the connecting beam 333 and the end of the second side member 332 facing away from the connecting beam 333 are the first ends of the frame body 33. In this way, the connection beam 333 is movable by driving the telescopic rod 71 of the first driver 70, so that the connection beam 333 can swing around the first end of the frame 33, and the second transfer mechanism 30 can be switched between the transfer position and the stop position.

As shown in fig. 1 to 4, the conveying device further includes an elastic tensioning block 60 provided on the bracket 10, the elastic tensioning block 60 being provided inside the third driving belt 50, the elastic tensioning block 60 being in tensioning engagement with the third driving belt 50. The provision of the elastic tensioning block 60 enables the third drive belt 50 to be maintained in a tensioned state when the second conveying mechanism 30 is switched between the conveying position and the stop position, so that the synchronous rolling of the first roller 21 and the second roller 31 is more reliable.

As shown in fig. 1 to 4, the first driving member 70 is fixedly provided on the bracket 10, and the telescopic rod 71 is movably connected to the lower end of the connection beam 333 through the hinge structure 80. The hinge structure 80 is configured such that when the connection beam 333 is driven by the telescopic rod 71, the connection beam 333 can rotate relative to the telescopic rod 71, so that a moving track of the connection beam 333 can be arc-shaped, and the connection beam 333 can swing around the first end of the frame 33. The condition that the moving track of the connecting beam 333 is a straight line due to the fixed connection of the telescopic rod 71 and the lower end of the connecting beam 333 is avoided.
