Description

Technical Field

[0001] The utility model relates to a pressure wheel surface lubrication device. Background Art

[0002] During the cigarette packaging production process, a plurality of felts arranged side by side along the rotation direction of the pressing wheel are installed between the label paper pressing wheel conveying device and the cover plate. The felt is installed on the cover plate by passing bolts through the holes of the felt and the cover plate, and locking the other end surface of the cover plate with nuts. A through hole is opened in the cover plate, and paraffin oil is injected into the hole to make the paraffin oil flow to the surface of the felt and penetrate downward. The felt and the pressing wheel are always in contact, so that the pressing wheel can smear paraffin oil on the surface of the label paper while conveying the label paper, so as to achieve the purpose of improving the packaging quality. However, due to the different surface friction coefficients of materials between different material suppliers or different brands, the demand for paraffin oil is also different, and sometimes even lubrication is not necessary. At this time, it takes a long time and is not convenient to remove the felt. If the cover plate is directly removed, there is no cover protection above the fast-rotating pressing wheel, which poses a safety hazard. On the other hand, paraffin oil flows directly into the felt from the through hole. Since the felt penetrates slowly and there is a gap between it and the cover plate, when too much paraffin oil is injected, the paraffin oil that does not have time to penetrate will flow into the equipment from the edge of the felt along the surface of the felt. Therefore, the uniformity and continuity of lubrication are not good, and it will cause pollution to the inside of the equipment. Utility Model Content

The lower end face maintains contact with the exposed surface of the outer wheel of the pressure wheel 11 directly below along the entire axial length of the wheel body, and the vertical spacing between the felt 46 and the pressure wheel 11 directly below is adjustable.

[0027] In a specific implementation, the corresponding structural setting of the device also includes:

[0028] The refueling structure 4 includes a top plate 42, a pair of side plates 44, and a felt 46. The top plate 42 is detachably mounted on the lower end of the cover plate 3 by means of fixing bolts 43. A concave groove is formed in the center of the upper end surface. An oil storage cavity 41 is formed between the top plate 42 and the cover plate 3. A plurality of oil holes 411 are provided at the bottom of the groove.

[0034] When this device is used to lubricate the surface of the pressure wheel, the convenience of operation is reflected in the following aspects:

[0038] Third, the refueling structure itself is easy to disassemble and assemble, which mainly involves two points;

[0039] The first point is to adjust the vertical spacing between the felt and the pressing wheel directly below. By using the oblong holes on the side panels and adjusting the vertical installation position of the side panels, the position of the felt supported by the side panels can be adjusted, and then the relative spacing between the felt and the pressing wheel directly below can be conveniently adjusted until the felt can maintain contact with the exposed surface of the outer wheel of the pressing wheel facing upward;

[0040] The second point is that the felt is easy to replace. Since the felt is placed in a space surrounded by a top plate and a pair of side plates with horizontal flanges, the felt can be directly pulled out, making replacement more convenient.

[0041] Fourth, it is more convenient to add oil to the felt;

[0042] By adding paraffin oil into the oil storage chamber through the oil filling hole on the cover plate, the paraffin oil can flow into the felt through the oil hole of the oil storage chamber. Furthermore, due to the setting of the oil storage chamber, a certain amount of paraffin oil can be stored, which can achieve continuous and slow flow into the felt through the oil hole, ensuring continuous and uniform lubrication of the pressure wheel, reducing the waste of paraffin oil, and avoiding pollution to the equipment caused by oil leakage.

[0043] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
