As shown in fig. 1, the rack 3 is provided with a guide rail 4 for conveying the sealing cover to a position directly above the tank, and the guide rail 4 and the conveyor belt 1 are arranged perpendicular to each other in this embodiment. The guide rail 4 comprises an inclined input section 43 and a horizontal positioning section 44, in the embodiment, the inclination angle of the input section 43 is 30 degrees, the smaller inclination angle of the input section 43 enables the transition between the input section 43 and the positioning section 44 to be smoother, and the sealing cover is prevented from being clamped at the transition between the positioning section 44 and the input section 43. The positioning section 44 is arranged at the lower end of the input section 43, the positioning section 44 is arranged right above the oil tank, and the end of the positioning section 44 far away from the input section 43 is provided with a baffle plate 42 for preventing the sealing cover from leaving the guide rail 4 from the end of the positioning section 44 far away from the input section 43. One end of the input section 43, which is far away from the positioning section 44, is provided with a placing tank 5, a vibration motor 51 is arranged on the side wall of the placing tank 5, a discharge port 52 is arranged at the joint of the placing tank 5 and the guide rail 4, and the size of the discharge port 52 is only used for one sealing cover to pass through. After the sealing covers are placed in the placing tank 5, the sealing covers move towards the discharge port 52 under the action of gravity and the vibration force of the vibration motor 51, and only one sealing cover passes through the discharge port 52, so that the sealing covers reaching the guide rail 4 are sequentially arranged, and the labor intensity of operators is reduced. The vibration motor 51 is provided to vibrate the sealing cover in the setting tank 5, thereby reducing the phenomenon that the sealing cover is clamped in the setting tank 5.

As shown in fig. 1 and 2, the guide rail 4 includes two plates 41 with L-shaped cross sections, the concave sides of the two plates 41 are disposed opposite to each other to form an inverted n-shape, the plate 41 includes a vertical limiting section 411 and a horizontal supporting section 412, and the convex portion of the sealing cover is disposed between the opposite surfaces of the supporting sections 412 of the two plates 41. The side wall of the supporting section 412 far away from the ground is contacted with the flange of the sealing cover, and the conveying section is provided with a pressing roller 45 for attaching the flange of the sealing cover to the supporting section 412; in the embodiment, the rubber pad is arranged on the end face of the pressing roller 45, which is used for being in contact with the sealing cover, and the arrangement of the rubber pad reduces the rigid abrasion between the pressing roller 45 and the sealing cover and reduces the probability of damaging the sealing cover; meanwhile, the friction force between the sealing cover and the pressing roller 45 is increased due to the arrangement of the rubber pad, so that the pressing roller 45 can move the sealing cover more easily. The bracket 3 is provided with a motor 46 for driving the pressing roller 45 to rotate.

As shown in fig. 1 and 2, a pushing cylinder 47 for pushing the inverted seal cover out of the guide rail 4 is arranged on one side of the pressing roller 45 close to the placing tank 5, a telescopic end of the pushing cylinder 47 is perpendicular to the guide rail 4, a groove 4111 is formed in the limiting section 411 opposite to the telescopic end of the pushing cylinder 47, and the minimum distance between the telescopic end of the pushing cylinder 47 and the supporting section 412 is greater than the thickness of the rib of the seal cover and less than the total thickness of the seal cover. A collecting box 6 for receiving the sealing cover is arranged right below the ground groove 4111.

As shown in fig. 3 and 4, the supporting section 412 of the plate 41 at the positioning section 44 is hinged to the limiting section 411, a torsion spring 413 is disposed at the hinged position, and two legs of the torsion spring 413 are respectively connected to the supporting section 412 and the limiting section 411. The baffle 42 is provided with a limiting block 421 for making the supporting section 412 and the limiting section 411 perpendicular to each other. In the present embodiment, the length of the pressing block 22 in the vertical direction is greater than the distance between the side wall of the positioning section 44 close to the ground and the upper edge of the tank opening. The supporting section 412 is always kept at the rotated position when the pressing block 22 presses the sealing cover, so that the phenomenon that the pressing block 22 is clamped at the supporting section 412 when the pressing block 22 returns to the initial position is reduced, meanwhile, the phenomenon that the sealing cover is in contact with the end face of the pressing block 22 far away from the ground is reduced, and the phenomenon that the pressing block 22 separates the sealing cover from the guide rail 4 when the pressing block returns to the initial position is reduced.

The process of capping: the operator places the sealing cover into the placing tank 5, then the vibration motor 51 vibrates, at this moment, the sealing cover moves towards the discharge hole 52 under the action of gravity and the vibration force of the vibration motor 51, and the sealing cover sequentially penetrates through the discharge hole 52 and is arranged on the guide rail 4. The sealing cover moves along the inclined guide rail 4 under the action of the self gravity of the sealing cover, when the sealing cover moves to the moving cylinder, if the protruding part of the sealing cover is arranged close to the ground, the flange of the sealing cover is attached to the supporting section 412 of the guide rail 4, and the sealing cover penetrates through a gap between the pushing cylinder 47 and the supporting section 412 and leaves the pushing cylinder 47; if the convex part of the sealing cover is far away from the ground, that is, the sealing cover is inverted, then the pushing cylinder 47 contacts with the convex part of the sealing cover and pushes the sealing cover to move, so that the sealing cover leaves the guide rail 4 from the groove 4111 and falls into the collecting box 6 under the action of gravity. After the sealing cover penetrates through the gap between the pushing cylinder 47 and the supporting section 412, the sealing cover continuously slides along the guide rail 4 to reach the pressing roller 45, the pressing roller 45 presses the sealing cover with the flange not jointed with the supporting section 412 so that the flange of the sealing cover is jointed with the supporting section 412, and the phenomenon that the sealing cover is clamped on the guide rail 4 is reduced. Meanwhile, the pressing roller 45 provides a thrust force for the sealing cover, so that the sealing cover can move towards the direction of the positioning section 44, and the phenomenon that the sealing cover is clamped on the guide rail 4 due to the fact that the inclined angle of the guide rail 4 is small is reduced. After the sealing cover moves to the positioning section 44, the sealing cover is in contact with the baffle plate 42 and fixed at the current position, at the moment, the working cylinder 21 extends to enable the pressing block 22 to push the sealing cover to move downwards, at the moment, the supporting section 412 and the rotating part are under the action of the thrust of the working cylinder 21, the torsion spring 413 deforms, the working cylinder 21 can push the sealing cover to move towards the direction of the oil tank, after the sealing cover is tightly abutted to the oil tank, the working cylinder 21 contracts, when the working cylinder 21 retracts to the initial position, the torsion spring 413 recovers to deform to enable the supporting section 412 to return to the initial position, the sealing cover slides to be in contact with the baffle plate 42 under the action of mutual pushing between gravity and the sealing cover, the conveying belt 1 drives the oil tank to move to enable the unsealed oil tank to be aligned to the working cylinder.
