The chain and sprocket linkage mechanism 16 is arranged below the mounting seat 11, all the rotating shafts 12 are linked through the chain and sprocket linkage mechanism 16, and the motor 17 drives the chain and sprocket linkage mechanism 16 to rotate through the speed reducer. The chain and sprocket linkage mechanism 16 of the present invention is a conventional linkage structure (a structure commonly used in a driving roller), and therefore, the present invention will not be described in detail with respect to this structure and the installation manner thereof. The barrel brush 13 is also an existing structure, and the detailed structure of the barrel brush 13 is not described in detail.

A plurality of retainer rings 14 are fixedly connected to the upper end face of the mounting seat 11, one bucket brush 13 is arranged in one retainer ring 14 and is arranged coaxially with the retainer ring 14, two spongy cushions 15 are elastically supported on the inner wall of each retainer ring 14, the two spongy cushions 15 are arranged oppositely and are arranged vertically, and a brushing cavity 100 is formed between the inner end face of each spongy cushion 15 and the outer wall of the bucket brush 13.

A plurality of groups of insertion holes are formed in the base plate 21, and are positioned above one barrel brush 13, each group of insertion holes comprises two through holes, and two end edges of the U-shaped bolt are inserted into the brushing cavity 100 in each check ring 14 through the two through holes in each group of insertion holes; two spongy cushions 15 in each retainer ring 14 are attached to the two end edges of the U-shaped bolt.

And the peristaltic pump injects lubricating grease into the oil pipe 22, the lubricating grease flows into the barrel brush 13, and the barrel brush 13 rotates to coat the lubricating grease on the thread surfaces on the two end edges of the U-shaped bolt. The bucket brushes 13 rotate, and the lubricating grease can be thrown out due to centrifugal force, and a retainer ring 14 is arranged on the outer side of each bucket brush 13, so that the retainer ring 14 can effectively prevent the lubricating grease from flying around, and the lubricating grease is concentrated in the retainer ring 14. The sponge cushion 15 is arranged in the retainer ring 14, and the sponge cushion 15 can absorb a part of lubricating grease, so that the U-shaped bolt can be coated more uniformly and fully.

For the convenience of the elastic support of the spongy cushion 15 on the inner wall of the retainer ring 14, two connecting plates 141 are arranged in each retainer ring 14, the two spongy cushions 15 are respectively fixed on the two connecting plates 141, a guide rod is fixed on each connecting plate 141, the guide rods are inserted into the retainer rings 14, and springs are sleeved on the guide rods.

In order to facilitate the phenomenon of oil accumulation in the retainer ring 14, a plurality of circular oil collecting grooves 111 are arranged on the upper end surface of the mounting seat 11, one oil collecting groove 111 is arranged on the inner side of one retainer ring 14 and is arranged coaxially with the retainer ring 14, a spongy cushion in the retainer ring 14 is arranged above the oil collecting groove 111, and oil dripping from the retainer ring 14 directly flows into the oil collecting groove 111.

In order to facilitate the draining of the oil in the oil collecting tank 111, a plurality of oil leakage holes 112 are formed in the lower end surface of the mounting base 11, and one oil leakage hole 112 is communicated with one oil collecting tank 111.

After the oiling of the U-shaped bolts is completed, the U-shaped bolts need to be taken out from the base plate 21, and since the oiling operation is performed on a plurality of U-shaped bolts at a time, if the bolts are taken down one by one, an efficient effect cannot be achieved. Therefore, the invention designs the unloading mechanism 3, the bolt can be completely taken down by the unloading mechanism 3 at one time, and the unloading mechanism 3 also has the positioning function, so that the phenomenon that the bolt moves up and down in the oil coating process is avoided.

The discharge mechanism 3 is described in detail below:

the discharging mechanism 3 comprises a cylinder 31, a fixing plate 32, a pre-positioning pressing plate 33 and a discharging plate 34, the fixing plate 32 and the pre-positioning pressing plate 33 are layered from top to bottom and are arranged above the base plate 21 in parallel, the pre-positioning pressing plate 33 is elastically connected to the fixing plate 32, a cylinder shaft of the cylinder 31 is fixedly connected with the fixing plate 32, the cylinder 31 drives the fixing plate 32 and the pre-positioning pressing plate 33 to move downwards simultaneously, the discharging plate 34 is movably inserted into the pre-positioning pressing plate 33, and when the U-shaped bolt is discharged, the discharging plate 34 is inserted into the space between two end edges of the U-shaped.

In order to elastically connect the pre-positioning pressing plate 33 to the fixing plate 32, a guide rod 35 is inserted into the fixing plate 32, the bottom end of the guide rod 35 is fixedly connected with the pre-positioning pressing plate 33, a spring 36 is sleeved on the guide rod 35, and the upper end and the lower end of the spring 36 respectively abut against the fixing plate 32 and the pre-positioning pressing plate 33.

A stopper rod 37 is provided on the lower end surface of the fixed plate 32.

When the bolt is oiled, cylinder 31 drive fixed plate 32 and prepositioning clamp plate 33 move down simultaneously, and prepositioning clamp plate 33 is pressed earlier and is touched on the bolt, and then cylinder 31 continues to stretch out, and spring 36 is compressed, and when gag lever post 37 contradicted on prepositioning clamp plate 33, the cylinder stopped stretching out, and the bolt was compressed tightly on base plate 21 this moment, avoids the bolt to play the phenomenon from top to bottom that appears in the fat liquoring in-process.

The discharging plate 34 of the present invention comprises a plate body 341 and a discharging rod body 342, wherein a plurality of discharging rod bodies 342 are fixed on the plate body 341 at certain intervals, a limiting platform part 343 is arranged at the tail end of each discharging rod body 342, and when a U-shaped bolt is discharged, one discharging rod body 342 is inserted into one U-shaped bolt.

In order to facilitate the insertion and installation of the discharging plate 34 on the pre-positioning pressing plate 33, a plurality of insertion lugs 338 are arranged on the rear side of the lower end surface of the pre-positioning pressing plate 33, and a discharging rod body 342 is inserted into one insertion lug 338.

The unloading process is explained in detail with reference to fig. 4, 5 and 6:

after the U-shaped bolt is oiled, the unloading rod body 342 is manually inserted into one U-shaped bolt, then the cylinder shaft retracts, and the limiting table part 343 drives the bolt to move upwards. The stripper plate 34 can remove the used U-bolt from the base plate 21 at one time, and the efficiency is high. During the U-bolt oiling process, the stripper plate 34 is in the state shown in fig. 4, and the stop block portion 343 abuts against the lower end surface of the pre-positioning pressure plate 33 under the action of gravity.

When the pre-positioning pressing plate 33 is pressed on the U-shaped bolt, in order to prevent the U-shaped bolt from being locked on the base plate 21, a plurality of groups of supporting ribs 211 are arranged on the upper end face of the base plate 21, and after the U-shaped bolt is inserted on the base plate 21, one U-shaped bolt is supported on one group of supporting ribs 211.

The foregoing is only a preferred embodiment of this invention and it should be noted that modifications can be made by those skilled in the art without departing from the principle of the invention and these modifications should also be considered as the protection scope of the invention.
