The carousel 23 is installed at the drive end of carousel actuating mechanism 24, and carousel actuating mechanism 24 is used for driving carousel 23 and rotates for bottom plate 21 to drive each second blanking hole 27 and link up with first blanking hole 26 in proper order, make the guide pulley of depositing in corresponding guide pulley work rest 25 drop into transfer cover 22 through second blanking hole 27, first blanking hole 26 in proper order, the guide pulley that is located the lower part in guide pulley work rest 25 drops to material loading station B department.

The guide wheel pushing part 3 is disposed at an edge side of the mounting table 1, and the guide wheel pushing part 3 is configured to reciprocate along a first horizontal direction so as to extend into the pushing groove 28 and push the guide wheel at the lowest part to the mounting station a, and exit the pushing groove 28 so that the next guide wheel falls to the feeding station.

The specific process of matching the guide wheel feeding part 2 and the guide wheel pushing part 3 with the feeding is as follows:

the turntable driving mechanism 24 first drives the turntable 23 to rotate relative to the bottom plate 21, so that the first blanking holes 26 are not communicated with all the second blanking holes 27 on the turntable 23. The guide wheels to be assembled are stacked into respective guide wheel holders 25.

The turntable driving mechanism 24 drives the turntable 23 to rotate relative to the bottom plate 21, so that one second blanking hole 27 is communicated with the first blanking hole 26, and therefore, the guide wheels stored in the guide wheel material frame 25 corresponding to the second blanking hole 27 fall into the transfer sleeve 22 through the second blanking hole 27 and the first blanking hole 26 in sequence, and the guide wheel at the lowest part falls into the feeding station B of the mounting table 1.

The guide wheel pushing part 3 reciprocates along the first horizontal direction, so that the guide wheels in the guide wheel material frame 25 are sequentially pushed to the installation station A.

When all the guide wheels in the guide wheel frame 25 are pushed out, the turntable driving mechanism 24 drives the turntable 23 to rotate relative to the bottom plate 21 again, so that the adjacent other second blanking hole 27 is communicated with the first blanking hole 26, and the guide wheel pushing part 3 starts pushing the guide wheels in the guide wheel frame 25 corresponding to the other second blanking hole 27. Meanwhile, the guide wheels to be assembled can be supplemented into the guide wheel frame 25 which is pushed to be empty, and of course, the guide wheels can be supplemented into the empty guide wheel frame 25 at intervals of preset time.

Through the cooperation of guide wheel feed portion and guide wheel pushing part, the guide wheel in the guide wheel work or material rest is pushed to the installation station department one by one to realize the autoloading to the guide wheel. In particular, by setting the distance between the transfer sleeve 22 and the mounting table 1 (i.e., the height of the pushing slot 28), it is ensured that the guide wheel pushing portion pushes only one guide wheel to the mounting station a at a time without carrying out the guide wheel above the pushed guide wheel, and also without carrying out the guide wheel falling thereon when the guide wheel pushing portion exits the pushing slot 28.

Optionally, the guide wheel pushing part 3 includes a pushing cylinder 31 and a pushing plate 32, where: the pushing plate 32 is connected to a driving end of the pushing cylinder 31, and the pushing cylinder 31 is used for driving the pushing plate 32 to move toward or away from the mounting table 1 along the first horizontal direction.

When the pushing cylinder 31 drives the pushing plate 32 to move toward the mounting table 1, the pushing plate 32 is inserted into the pushing groove 28, and pushes the guide wheel falling to the feeding station B to the mounting station a, and the guide wheel above the pushed guide wheel is supported on the pushing plate 32.

When the pushing cylinder 31 drives the pushing plate 32 to move away from the mounting table 1, the pushing plate 32 leaves the pushing groove 28, and the guide wheel supported on the pushing plate 32 falls to the feeding station B.

In this way, it can be ensured that when the pushing cylinder 31 drives the pushing plate 32 to reciprocate towards or away from the mounting table 1 along the first horizontal direction, the guide wheels in the current guide wheel work rest 25 can be sequentially pushed to the mounting station A.

With continued reference to fig. 4, optionally, the guide wheel feeding mechanism in the embodiment of the present utility model further includes a photoelectric sensor 6 disposed on the bottom plate 21 and located at an edge side of the guide wheel frame 25, and when a predetermined one of the guide wheel frames 25 rotates to the position of the photoelectric sensor 6, the photoelectric sensor 6 generates a feeding signal.

In this way, it can be ensured that when a predetermined idler frame 25 which is pushed to be empty after being fed rotates to the photoelectric sensor 6, the photoelectric sensor 6 can be triggered to generate a feeding signal, so that timely feeding is conveniently carried out on the pushed idler frame 25.

The embodiment of the utility model provides a guide wheel clamping part 4, as shown in fig. 6, the guide wheel clamping part 4 comprises a clamping driving part 41, a sliding rail 42, a first sliding block 43, a second sliding block 44, a first clamping part 45 and a second clamping part 46, wherein:

The second clamping portion 46 is connected to the second slider 44, and a clamping end of the second clamping portion 46 extends upward out of the mounting table 1 and is located at a second side of the mounting station a opposite to the first side.

When the clamping driving part 41 drives the first slider 43 and the second slider 44 to slide towards each other along the slide rail 42, the clamping end of the first clamping part 45 and the clamping end of the second clamping part 46 clamp the guide wheel at the installation station a.

When the clamping driving part 41 drives the first slider 43 and the second slider 44 to slide along the slide rail 42 to separate to both sides, the clamping ends of the first clamping part 45 and the second clamping part 46 release the guide wheels.

At the same time, the compression spring 413 is compressed.

When the telescopic cylinder 411 drives the driving block 412 to move away from the installation station a, the compression spring 413 is decompressed and stretched, so that the first slider 43 and the second slider 44 are pushed to slide along the sliding rail 42 to separate to two sides, and the clamping end of the first clamping portion 45 and the clamping end of the second clamping portion 46 are driven to release the guide wheels at the installation station a.
