A connecting groove 611 is provided inside the bending frame 61. A limiting rod 612 is provided at the inward bending of the bending frame 61. The limiting rod 612 is located inside the connecting groove 611 and is fixedly connected to the inner wall of the connecting groove 611. The left and right ends of the bending frame 61 are respectively threadedly connected with a fixing rod 1 62 and a fixing rod 2 63 through a threaded sleeve. The fixing rod 1 62 and the fixing rod 2 63 are connected to the ends away from the bending frame 61. The extrusion mechanism 64 and the inner wall of the connecting groove 611 are fixedly connected with a sliding rod 613, and the outer surface of the sliding rod 613 is slidably sleeved with a connecting sleeve 65. The distance between the connecting sleeve 65 and the adjacent limiting rod 612 is short, ensuring that the placement block 67 will not affect the normal sliding of the lubricating oil bottle. The outer surfaces of the two groups of connecting sleeves 65 are fixedly connected with fixed rods three 66. A placement block 67 is arranged on the outer side of the sliding rod 613.

The end of the connecting rod 644 away from the cleaning block 642 is located inside the slot 648. The ends of the limit block 1 641, the cleaning block 642 and the limit block 2 643 away from the bending frame 61 are all arranged obliquely outward, and the surfaces of the limit block 1 641, the cleaning block 642 and the limit block 2 643 are all embedded with balls 649, and the surface of the cleaning block 642 is bonded with a cleaning cloth 647.

[0028] The working principle of this embodiment is as follows: the lubricating oil bottle is placed on the roller, with the mouth of the lubricating oil bottle placed downward and the mouth of the bottle close to the roller, and the lubricating oil bottle slides downward along the roller, and when the lubricating oil bottle slides, the lubricating oil bottle contacts the limit block 1 641, and with the assistance of the ball 649, the lubricating oil bottle slides downward to the cleaning block 642 and contacts the cleaning cloth 647, and the lubricating oil on the surface of the lubricating oil bottle is wiped off by the cleaning cloth 647, and the lubricating oil bottle continues to slide down along the roller while being contacted by the cleaning cloth 647, and directly slides to the limit block 2 643, and slides to the next row of rollers under the restriction of the limit block 2 643, and then performs the subsequent packing process.

[0029] Example 2, based on Example 1, please refer to Figure 7-8 The present invention provides a technical solution: the contact mechanism 68 includes a vertical rod 681, the bottom of the vertical rod 681 is fixedly connected to the top of the placement block 67, the upper end of the vertical rod 681 contacts the cleaning block 642, the outer surface of the lower end of the vertical rod 681 is fixedly sleeved with a clamping sleeve 682, a knocking plate 684 is arranged inside the clamping sleeve 682, the bottom of the knocking plate 684 is rotatably connected to a connecting block 683 through a rotating shaft, the knocking plate 684 contacts the cleaning cloth 647, and the bottom of the connecting block 683 is fixedly connected to the top of the placement block 67.

[0030] A circular spring 685 is disposed inside the sleeve 682, and the two ends of the circular spring 685 are respectively fixedly connected to the surface of the knocking plate 684 and the vertical rod 681. A heavy ball 687 is disposed on the outer surface of the knocking plate 684, and a pull rope 686 is fixedly connected to the outer surface of the knocking plate 684. The pull rope 686 penetrates the heavy ball 687. The working principle of this embodiment is as follows: when the lubricating oil bottle slides down along the roller, the placing block 67 contacts the surface of the roller, so the placing block 67 slides downward under the drive of the roller, and the placing block 67 drives the connecting sleeve 65 to slide along the sliding rod 613 through the fixed rod 3 66 connected thereto, until the fixed rod 3 66 contacts the limiting rod 612, and the placing block 67 squeezes the cleaning cloth 647 when sliding along the roller, so that the cleaning cloth fits the lubricating oil bottle more closely; When the placement block 67 slides, the vertical rod 681 is driven to move. At the same time, because the slide bar 613 is inclined, after the placement block 67 slides along the slide bar 613, the vertical rod 681 can be gradually driven to squeeze the cleaning block 642, so that the cleaning block 642 can be squeezed through the square spring 1 645 to deflect inward, so that the cleaning block 642 can be closer to the lubricating oil bottle body; When the fixing rod three 66 contacts the limiting rod 612, the placing block 67 moves to the maximum position, and then with the continuous rotation of the roller, the placing block 67 will be driven to swing up and down slightly. Therefore, when the placing block 67 swings, the heavy ball 687 pulls the knocking plate 684 through the pull rope 1 686, so that the knocking plate 684 continuously knocks the cleaning cloth 647 under the restriction of the circular spring 1 685, so that the cleaning cloth 647 fits better with the lubricating oil bottle.

[0031] Example 3, based on Example 1 and Example 2, please refer to Fig. 9 The present invention provides a technical solution: the scratching mechanism 69 includes a placing plate 691, a placing groove is opened inside the placing plate 691, a leakage groove 692 is opened at the central axis of the placing groove wall, the bottom of the placing groove is arc-shaped, so that the adsorbed lubricating oil is conveniently gathered in the middle and then discharged from the leakage groove 692, and a pull rope 695 and a circular spring 696 are fixedly connected to the bottom of the placing plate 691, and the tops of the pull rope 695 and the circular spring 696 are fixedly connected to the bottom of the placing block 67.

[0032] A protrusion 1 693 and a protrusion 2 694 are fixedly connected to the top of the placement groove wall. The protrusion 1 693 is located on the left side of the protrusion 2 694, and the height of the protrusion 1 693 is greater than the height of the protrusion 2 694.

[0033] A bending plate 697 is provided on the top of the second protrusion 694, and a plurality of leakage holes are opened on the surface of 697. The bending plate 697 is rotatably connected to the wall of the placement groove through a rotating shaft. The left side of the top of the second protrusion 694 is in contact with the bending plate 697, and the right side of the top of the second protrusion 694 is bent downward. Cleaning cotton 698 is bonded to the inner wall of the placement groove, and the right side of the top of the cleaning cotton 698 is inclined to facilitate cleaning of the roller.

[0034] The working principle of this embodiment is as follows: as the placement block 67 moves, the placement block 67 drives the cleaning cotton 698 to approach the roller through the pull rope 2 695 and the circular spring 2 696, and then as the placement block 67 continues to move, the cleaning cotton 698 stretches the circular spring 2 696 to tilt toward the approaching roller, so that the roller can be cleaned through the inclined part of the cleaning cotton 698, and the raised part of the cleaning cotton 698 cleans the bottom of the lubricating oil bottle. At the same time, when the cleaning cotton 698 approaches the roller, the bending plate 697 can be squeezed and deflected, so that the raised area of ​​the cleaning cotton 698 is more closely fitted to the lubricating oil bottle body.
