The embodiment of the present application discloses a lifting and discontinuous conveying device.

6 and 7 , the difference between the lifting intermittent conveying device disclosed in the embodiment of the present application and the embodiment 1 is that:

In this embodiment, a mounting frame 45 is fixedly installed on one side of the feed rack 41, one end of one of the feed conveying rollers 42 of the feed rack 41 passes through the feed rack 41 and extends toward the mounting frame 45, and one end of one of the transfer conveying rollers 32 in each transfer rack 31 passes through the transfer rack 31; the transfer drive assembly 43 includes a rotating sleeve 431, a docking strip 432, a linkage cylinder 434 and a synchronization part, and the rotating sleeve 431 is rotatably installed on the mounting frame 45. When the feed rack 41 is lifted to the same height as the transfer rack 31, the axial direction of the rotating sleeve 431 remains coaxial with the axial direction of the transfer conveying roller 32 extending from the corresponding transfer rack 31.

6 and 7 , the docking strip 432 is slidably inserted into the rotating sleeve 431, and the cross-section of the docking strip 432 is a polygon. The shape of the inner wall of the rotating sleeve 431 is matched with the shape of the docking strip 432, so that the docking strip 432 and the rotating sleeve 431 are circumferentially linked (that is, the rotating sleeve 431 can drive the docking strip 432 to rotate); a docking groove 321 is provided on the end surface of the transfer conveying roller 32 close to the mounting frame 45, and the shape of the docking groove 321 is matched with the shape of the docking strip 432. The cylinder body of the linkage cylinder 434 is fixedly installed on the mounting frame 45, and the piston rod of the linkage cylinder 434 penetrates the mounting frame 45 and abuts against the docking strip 432. When the piston rod of the linkage cylinder 434 extends outward, the docking strip 432 is matched and inserted into the docking groove 321, and the docking strip 432 and the transfer conveying roller 32 are circumferentially linked.

6 and 7 , a synchronous member is disposed on the mounting frame 45 to drive the feed conveying roller 42 and the rotating sleeve 431 to rotate synchronously. In this embodiment, the synchronous member is configured as a synchronous belt 439, which is sequentially wound around the feed conveying roller 42 and the rotating sleeve 431 to enable the feed conveying roller 42 and the rotating sleeve 431 to rotate synchronously.

It is particularly noted that since the distance between the material tray 7 and the transfer rack 31 is fixed, the number of rotations of the feed conveyor roller 42 and the transfer conveyor roller 32 is fixed; in specific applications, it is only necessary to adjust the angle of the transfer conveyor roller 32 in the initial state so that the docking groove 321 can be matched with the docking strip 432, so that when the feed rack 41 is lifted and docked with different transfer racks 31, the docking strip 432 can be inserted into the corresponding docking groove 321, so that the docking strip 432 can drive the transfer conveyor rollers 32 in all transfer racks 31.

The implementation principle of Example 2 of the present application is as follows: when the material tray 7 is transported from the feed rack 41 to the transfer rack 31, the feed rack 41 is lifted to a set height, and the docking strip 432 is driven to be inserted into the docking groove 321 through the linkage cylinder 434, and then the feed conveying roller 42 is driven to rotate. The setting of the rotating sleeve 431 and the docking strip 432 can make the feed conveying roller 42 and the transfer conveying roller 32 rotate synchronously, thereby transferring the material tray 7 to the transfer rack 31 and reducing the manufacturing cost of the overall structure.

Embodiment 3:

The embodiment of the present application discloses a lifting and discontinuous conveying device.

8 and 9 , the difference between the lifting intermittent conveying device disclosed in the embodiment of the present application and the embodiment 1 is that:

In this embodiment, a mounting frame 45 is fixedly installed on one side of the feed rack 41, one end of one of the feed conveying rollers 42 of the feed rack 41 passes through the feed rack 41 and extends to the mounting frame 45, one end of one of the transfer conveying rollers 32 in each transfer rack 31 passes through the transfer rack 31, and the transfer drive assembly 43 includes a rotating disk 435, a rotating rod 436, a pushing rod 437 and a synchronizing member. The rotating disk 435 is rotatably installed on the mounting frame 45, one end of the transfer conveying roller 32 passes through the transfer rack 31 and is connected to the rotating rod 436, and the axial normal state of the rotating rod 436 is vertically set.

Referring to Figures 8, 9 and 10, there are multiple push rods 437, which are arranged at intervals around the axial direction of the rotating disk 435. One end of each push rod 437 is fixedly installed on the rotating disk 435. A through channel 438 for the rotating rod 436 to pass through is formed between the multiple push rods 437. When the feed rack 41 is lifted to the same height as the transfer rack 31 and the rotating disk 435 is driven to rotate, the push rod 437 can push the rotating rod 436 and make the rotating rod 436 rotate around the axial direction of the transfer conveyor roller 32.

9 and 10, a synchronous member is disposed on the mounting frame 45 to drive the feed conveying roller 42 and the rotating disk 435 to rotate synchronously. In this embodiment, the synchronous member is configured as a synchronous belt 439, and the synchronous belt 439 is sequentially wound around the feed conveying roller 42 and the rotating disk 435 to enable the feed conveying roller 42 and the rotating disk 435 to rotate synchronously.

The implementation principle of Example 3 of the present application is as follows: after the lifting mechanism 2 lifts the feed rack 41 to the same height as the transfer rack 31, the rotating rod 436 passes through the passage 438 between multiple push rods 437, and then drives the feed conveyor roller 42 to rotate. The rotating disk 435 rotates with the feed conveyor roller 42 under the action of the synchronous belt 439, and the rotating disk 435 drives the push rod 437 to push the rotating rod 436 to rotate, so that the transfer conveyor roller 32 and the feed conveyor roller 42 can rotate synchronously to transport the support tray 7, thereby improving the convenience of driving the transfer conveyor roller 32 to rotate and further reducing the manufacturing cost of the overall structure.

The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
