[0011] Figure 3 It is a schematic diagram of the working state (direction two) of an embodiment of the present utility model. Detailed implementation manners

[0012] The following will describe the detailed implementation manners of the present utility model with reference to the accompanying drawings. As Figures 1 to 3 shown: A roller bed transmission device with a flipping function, which includes a support frame 1. A first conveyor belt is arranged on the support frame 1, and the first conveyor belt is driven by a first conveyor motor 3 arranged on the support frame 1.

[0013] One end of the support frame 1 is hinged with a flipping frame 4. A second conveyor belt is arranged on the flipping frame 4, and the second conveyor belt is driven by a second conveyor motor 6 arranged on the flipping frame 4.

[0014] A flipping motor 7 is fixedly supported inside the support frame 1. The flipping motor 7 is connected to a driving wheel 8 through a transmission pair. The driving wheel 8 is arranged on a flipping drive shaft 9 that is rotatably supported on the support frame 1. Both ends of the drive shaft 9 are provided with swing arms 10. One end of the swing arm 10 is hinged to one end of a connecting rod 11. The other end of the connecting rod 11 is rotatably supported on a hinge seat 12. The two hinge seats 12 are jointly connected to a connecting plate 13, and the connecting plate 13 is fixedly connected to the bottom end surface of the flipping frame 4.

[0015] The roller bed transmission device further includes a flipping frame support 14. A lower stop block 15 is arranged on the top end surface of the flipping frame support 14, and an upper stop block 16 that matches the lower stop block 15 is arranged on the bottom end surface of the flipping frame 4. When the upper stop block 16 contacts the lower stop block 15, the second conveyor belt and the first conveyor belt are in a coplanar state.

[0016] The working process of the roller bed transmission device with a flipping function according to an embodiment of the present utility model is as follows: In the normal working state, the flipping frame 4 is in a horizontal state, that is, the second conveyor belt and the first conveyor belt are in a coplanar state. The first conveyor motor 3 works to drive the first conveyor belt to rotate, and the second conveyor motor 6 works to drive the second conveyor belt to rotate. The two conveyor belts are connected end to end to jointly realize the conveying of workpieces.

[0017] When maintenance, routine maintenance and other operations are required, the first conveyor motor 3 and the second conveyor motor 6 can be controlled by the control system to stop working, and then the tilting motor 7 is controlled to work. The tilting motor 7 drives the driving wheel 8 to rotate through the transmission pair. The driving wheel 8 drives the tilting drive shaft 9 to rotate. The swing arms 10 at both ends of the tilting drive shaft 9 swing accordingly, and then drive the connecting rod 11 connected to it to jack up, driving the tilting frame 4 to make an overall tilting action relative to the support frame 1. After the movement is in place, the tilting motor 7 stops working and locks, and the tilting frame 4 stops moving. At this time, the tilting frame 4 is completely opened, and the operator can directly pass through from below the tilted tilting frame 4;

[0018] After the maintenance, maintenance and other operations are completed and the roller bed conveyor device needs to work normally, a signal is sent to the tilting motor 7. The tilting motor 7 controls the driving wheel 8 to rotate in the reverse direction, driving the tilting drive shaft 9 to rotate in the reverse direction, and then driving the swing arms 10 at both ends of it to swing in the reverse direction. The swing arm 10 pulls down the connecting rod 11, causing the tilting frame 4 to swing in the reverse direction until the upper stop block 16 on the bottom end surface of the tilting frame 4 presses on the lower stop block 15, and then the tilting motor 7 stops working. By controlling the output rotation speed of the tilting motor 7, the tilting frame 4 can be accurately controlled to stop moving after tilting in place. At this time, the first conveyor belt and the second conveyor belt return to the coplanar state again, and the control system controls the first conveyor motor 3 and the second conveyor motor 6 to work, and the roller bed transmission device restarts working.
