Description

Technical Field

[0001] This utility model belongs to the field of strip steel cleaning technology, specifically relating to an easily detachable roller device. Background Technology

[0002] Squeeze rollers / brush rollers are commonly used roller equipment in cold-rolled strip steel cleaning systems. They typically consist of a squeeze roller / brush roller assembly, bearing housings, wear-resistant plates, clamping plates, and a frame. The squeeze roller / brush roller assemblies are installed on the upper and lower sides of the strip steel passage line. Wear-resistant plates are installed on both sides of the bearing housings, allowing them to slide up and down along the slide rails on both sides of the frame. The squeeze rollers are closed by a drive mechanism, thus squeezing out the liquid from the strip steel surface. Existing squeeze rollers / brush rollers have grooves on both the operating and drive sides of the bearing housings. Axial positioning of the bearing housings is achieved by inserting clamping plates into these grooves and fixing the clamping plates to the frames on both sides. The operating side bearing is a fixed support point, while the drive side bearing is a floating support point. When changing rollers, the clamping plates on both the operating and drive sides of the bearing housings need to be removed separately, and then a special roller-changing lifting tool is used to pull the roller along with the bearing housing from the operating side. Because the cleaning system has many roller assemblies, a high roller-changing frequency, and a dense arrangement of drive-side transmission devices and pipelines, space is limited, making the removal and installation of the drive-side clamping plates very inconvenient.

[0014] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0015] The easily detachable roller device provided by this utility model has a simple structure and is easy to operate. While meeting the daily use of squeeze rollers / brush rollers, it simplifies roller replacement operations. When changing rollers, the fixed connection between the operating bearing seat and the corresponding mounting slot is released, allowing the roller body along with the bearing seat to be pulled out from the operating side. This requires minimal operating space and does not interfere with the densely arranged pipelines around the strip cleaning device, making disassembly and installation convenient.

Therefore, they should not be construed as limitations on this utility model.

[0024] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature; in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0025] Reference Figure 1-3This utility model provides an easily detachable roller device, including a first frame 1, a second frame 2, and a roller body 3. The roller body 3 is connected at both ends to a first bearing seat 4 and a second bearing seat 5 via bearings. The first frame 1 has a first radial limiting hole, and the second frame 2 has a second radial limiting hole. The first bearing seat 4 is detachably installed in the first radial limiting hole via a connector. The second bearing seat 5 is installed in the second radial limiting hole. In use, the first bearing seat 4 end is generally the operating side, and the second bearing seat 5 end is the transmission side. The second bearing seat 5 is installed in the second radial limiting hole, where radial limitation is only achieved, while axial freedom is maintained, allowing the transmission-side bearing and bearing seat to move axially with the roller shaft. The first bearing seat 4 is fixed in the first radial limiting hole via a connector, where radial limitation is achieved by the first radial limiting hole, and axial limitation is achieved by the connector, preventing the roller body 3 from detaching from the frame and affecting its use. When it is necessary to change the roller, disconnect the connection between the connector and the first radial limiting hole and / or the first bearing seat 4, so that the first bearing seat 4 is disengaged from the first radial limiting hole. Then the roller body 3 together with the bearing seat can be pulled out from the operating side. The operation is simple, requires little operating space, and does not affect the densely arranged pipelines around the strip steel cleaning device.

[0027] Furthermore, the connecting member includes a baffle 7; the baffle 7 is detachably connected to the first frame 1, and a first axial limiting groove is formed between the baffle 7 and the first frame 1; the first wear-resistant plate 6 is provided with a protrusion 601; the protrusion 601 is engaged in the first axial limiting groove.

[0028] In an optimized implementation, such as Figure 4 As shown, the first wear-resistant plate 6 is provided with a second axial limiting groove 602 that matches the first bearing seat 4 on the side facing the first bearing seat 4; the first bearing seat 4 is engaged in the second axial limiting groove 602, further limiting the axial direction of the first bearing seat 4.

[0029] Specifically, a second wear-resistant plate 8 is provided between the second bearing housing 5 and the second radial limiting hole; the second wear-resistant plate 8 is detachably connected to the second bearing housing 5 to reduce the wear of the second bearing housing 5.

[0030] In a more detailed embodiment, the thickness of the first wear-resistant plate 6 is greater than that of the second wear-resistant plate 8.

[0031] Optionally, the first wear-resistant plate 6 and the first bearing seat 4, the baffle 7 and the first frame 1, and the second wear-resistant plate 8 and the second bearing seat 5 are detachably connected by screws, which facilitates the installation and disassembly of the two components.

[0032] Preferably, the first bearing housing 4 and the second bearing housing 5 have the same structure and the same external dimensions, are interchangeable, and the spare parts can be standardized.

[0033] Furthermore, the bearings at both ends of the roller body 3 are fixed support points, and the outer ring of the bearing is provided with an end cap for axial positioning. The inner ring is preferably axially positioned by a shoulder and a round nut.

[0041] When it is necessary to change the roller, remove the screws between the baffle 7 and the first frame 1 to release the axial restriction of the first axial limiting groove on the first wear-resistant plate 6 and the first bearing seat 4. Then, pull the roller body 3 along with the bearing seat out from the operating end without affecting the densely arranged pipelines around the strip cleaning device. When it is necessary to replace the wear-resistant plate, simply remove the screws between the wear-resistant plate and the corresponding bearing seat.
