Description

Technical Field

[0001] This utility model relates to the field of carbon fiber production technology, specifically to a guide roller cleaning device for carbon fiber production. Background Technology

[0002] Carbon fiber production involves multiple complex processes, from the preparation of precursor fibers to carbonization. In these processes, carbon fiber precursor fibers or fiber bundles need to undergo continuous processing under the guidance of guide rollers. Guide rollers play an important role in supporting and guiding the movement of carbon fibers in carbon fiber production. They directly affect the production quality of carbon fibers, such as the uniformity of fiber tension and operational stability. If there are problems with the guide rollers, it may lead to a decrease in the surface quality of carbon fibers and defects such as fuzzy fibers and broken fibers.

[0003] The utility model patent application document with announcement number "CN219943782U" discloses a cleaning device for guide rollers used in carbon fiber production. The device includes a base, a support frame at the top of the base, a limiting block at the top of the support frame, a fixing bolt on one side of the limiting block, a main body for the carbon fiber production guide roller inside the limiting block, and a first support seat on one side of the support frame. This utility model, by setting a first cleaning blade, a second cleaning blade, a third cleaning blade, and a cleaning brush, allows for the sequential cleaning of fiber debris and residual resin adhering to the outer surface of the carbon fiber production guide roller body during use. Then, the cleaning brush removes any remaining debris after cleaning. This method improves the cleaning effect on the carbon fiber production guide roller body.

[0004] The carbon fiber production guide roller cleaning device disclosed in the aforementioned document has the following defects: With prolonged use, the cleaning brushes in this technical solution will inevitably wear down. When the cleaning brushes become shorter due to wear, they cannot effectively contact the guide roller surface, thus affecting the cleaning effect. Since the cleaning brushes in this technical solution are fixedly installed, they need to be replaced once they wear down to this extent. This frequent replacement of cleaning brushes increases production costs, as new cleaning brushes need to be constantly purchased; furthermore, frequent brush replacements also increase equipment downtime, thus affecting production efficiency.

[0005] Therefore, it can be seen that the existing guide roller cleaning device for carbon fiber production lacks a mechanism that can effectively adjust the cleaning brush after it wears down. It is necessary to improve the existing shortcomings and provide a guide roller cleaning device for carbon fiber production. Utility Model Content

[0006] The purpose of this invention is to provide a guide roller cleaning device for carbon fiber production, so as to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a guide roller cleaning device for carbon fiber production, comprising a base plate, two sets of brackets mounted on the upper surface of the base plate, a guide roller body rotatably connected between the two sets of brackets, a fixing plate fixedly mounted between the two sets of brackets, a vertical plate mounted on the upper surface of the fixing plate, a blade mounting plate mounted on the upper surface of the vertical plate, a first cleaning blade, a second cleaning blade, and a third cleaning blade respectively mounted on the upper surface of the blade mounting plate, and a cleaning mechanism mounted on the outer surface of the fixing plate, the cleaning mechanism including a threaded sleeve, the threaded sleeve being fixedly mounted on the upper surface of the fixing plate.

[0009] Furthermore, the cleaning mechanism also includes a screw, the inner surface of the threaded sleeve is threaded with the screw, and one end of the screw extends to the bottom of the fixed plate.

[0010] Furthermore, the cleaning mechanism also includes a rotary handle, which is fixedly installed at one end of the screw.

[0011] Furthermore, the cleaning mechanism also includes a cleaning brush mounting base, and the end of the screw away from the throttle is rotatably connected to the cleaning brush mounting base.

[0012] Furthermore, the cleaning mechanism also includes a cleaning brush, which is installed inside the cleaning brush mounting base and abuts against the outer surface of the guide roller body.

[0013] Furthermore, the cleaning mechanism also includes guide slides, and two sets of guide slides are fixedly installed on the lower surface of the cleaning brush mounting base. Both sets of guide slides are slidably connected to the inside of the fixed plate.

[0014] This utility model has the following beneficial effects:

[0015] This invention utilizes a rotating handle to drive a screw. Because the screw is threadedly connected to a threaded sleeve fixed to a fixed plate, the screw undergoes axial movement during rotation. One end of the screw is rotatably connected to a cleaning brush mounting base. As the screw moves axially, it causes the cleaning brush mounting base to move up and down. Two sets of guide rods on the lower surface of the cleaning brush mounting base are slidably connected to the inside of the fixed plate, ensuring the stability of the cleaning brush mounting base during its up-and-down movement. The cleaning brush, installed inside the cleaning brush mounting base, then abuts against the outer surface of the guide roller body. By adjusting the screw, the worn and shortened cleaning brush re-adheres to the guide roller surface to clean the guide roller body. This improves the overall service life of the cleaning brush, avoiding the need for replacement when it is worn and no longer in contact with the guide roller body, thus reducing the frequency of cleaning brush replacement and lowering operating costs.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 - Figure 4 As shown, this utility model is a guide roller cleaning device for carbon fiber production, including a base plate 1, two sets of brackets 2 are installed on the upper surface of the base plate 1, a guide roller body 3 is rotatably connected between the two sets of brackets 2, a fixing plate 4 is fixedly installed between the two sets of brackets 2, a vertical plate 5 is installed on the upper surface of the fixing plate 4, a blade mounting plate 6 is installed on the upper surface of the vertical plate 5, a first cleaning blade 7, a second cleaning blade 8 and a third cleaning blade 9 are respectively installed on the upper surface of the blade mounting plate 6, and a cleaning mechanism is installed on the outer surface of the fixing plate 4.

[0026] The cleaning mechanism includes a threaded sleeve 10, and the threaded sleeve 10 is fixedly installed on the upper surface of the fixing plate 4;

[0027] The cleaning mechanism also includes a screw 11, and the inner surface of the threaded sleeve 10 is threaded with the screw 11. One end of the screw 11 extends to the bottom of the fixing plate 4.

[0028] The cleaning mechanism also includes a handle 12, which is fixedly installed at one end of the screw 11;

[0029] The cleaning mechanism also includes a cleaning brush mounting base 13, and the end of the screw 11 away from the handle 12 is rotatably connected to the cleaning brush mounting base 13;

[0030] The cleaning mechanism also includes a cleaning brush 14, which is installed inside the cleaning brush mounting base 13. The cleaning brush 14 abuts against the outer surface of the guide roller body 3.

[0031] The cleaning mechanism also includes guide slide rods 15. Two sets of guide slide rods 15 are fixedly installed on the lower surface of the cleaning brush mounting base 13. Both sets of guide slide rods 15 are slidably connected to the inside of the fixing plate 4.

[0032] When the cleaning brush 14 wears down and shortens after prolonged use, and the guide roller body 3 can no longer make contact, rotating the handle 12 will cause the screw 11 to rotate. Because the screw 11 is threadedly connected to the threaded sleeve 10, which is fixed to the fixing plate 4, the screw 11 will move axially when it rotates. One end of the screw 11 is rotatably connected to the cleaning brush mounting base 13. When the screw 11 moves axially, it will cause the cleaning brush mounting base 13 to move up and down. The two sets of guide slides 15 on the lower surface of the cleaning brush mounting base 13 are connected to the inside of the fixing plate 4. The sliding connection ensures the stability of the cleaning brush mounting base 13 when it moves up and down. Then, the cleaning brush 14 installed inside the cleaning brush mounting base 13 abuts against the outer surface of the guide roller body 3. By adjusting the screw 11, the worn and shortened cleaning brush 14 is made to re-adhere to the surface of the guide roller to clean the guide roller body 3. This improves the overall service life of the cleaning brush 14 and avoids the situation where it needs to be replaced when it is worn and shortened and can no longer contact the guide roller body 3. This reduces the replacement frequency of the cleaning brush 14 and thus reduces the cost of use.

[0033] In use, when the guide roller body 3 rotates, impurities on its outer surface come into contact with the first cleaning blade 7, the second cleaning blade 8, and the third cleaning blade 9. Due to the rotation of the guide roller, these blades can scrape off relatively hard and firmly attached impurities from the guide roller surface. At the same time, the cleaning brush 14 can brush off finer impurities such as dust and fiber debris from the guide roller surface.

[0034] When the cleaning brush 14 wears down and shortens after prolonged use, and the guide roller body 3 can no longer make contact, rotating the handle 12 will cause the screw 11 to rotate. Because the screw 11 is threadedly connected to the threaded sleeve 10, which is fixed to the fixing plate 4, the screw 11 will move axially when it rotates. One end of the screw 11 is rotatably connected to the cleaning brush mounting base 13. When the screw 11 moves axially, it will cause the cleaning brush mounting base 13 to move up and down. The two sets of guide slides 15 on the lower surface of the cleaning brush mounting base 13 are connected to the inside of the fixing plate 4. The sliding connection ensures the stability of the cleaning brush mounting base 13 when it moves up and down. Then, the cleaning brush 14 installed inside the cleaning brush mounting base 13 abuts against the outer surface of the guide roller body 3. By adjusting the screw 11, the worn and shortened cleaning brush 14 is made to re-adhere to the surface of the guide roller to clean the guide roller body 3. This improves the overall service life of the cleaning brush 14 and avoids the situation where it needs to be replaced when it is worn and shortened and can no longer contact the guide roller body 3. This reduces the replacement frequency of the cleaning brush 14 and thus reduces the cost of use.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
