Description

Technical Field

[0001] This utility model relates to the field of steel rolling technology, specifically to a support roller cleaning device. Background Technology

[0002] During the dry leveling process of strip steel, cold and hot leveling machines generate metallic dust and contaminants such as iron oxide scale on the strip surface. During rolling, these contaminants adhere to the work roll surface and are gradually transferred to the support rolls through surface contact. Because the support roll replacement cycle is relatively long, contaminants accumulate on the support roll surface over time. Even when the work roll is replaced, the work roll surface is subject to cross-contamination from the support roll surface, continuously transferring contaminants to the strip surface. This not only reduces product quality but also increases the wear and tear on the leveling machine rolls. Therefore, periodically and effectively cleaning the contaminants on the support roll surface is a crucial method to ensure the surface quality of the strip steel.

[0003] Chinese Utility Model Patent Publication No. CN 209206044 U discloses a support roller surface cleaning device. This device, through a transverse movement mechanism, can drive a wiping mechanism to move along the axial direction of the support roller, thereby performing transverse and comprehensive wiping on the surface of the strip steel. Simultaneously, a wiping head is provided, which approaches the support roller surface under the action of a wiping drive cylinder. A continuously rotating wiping belt is provided on the outer surface of the wiping head, which can continuously refresh the surface of the wiping belt for better cleaning of the support roller surface. However, although this support roller surface cleaning device can move, it lacks a side cleaning structure, which can easily lead to coolant residue, affecting the normal operation of the rolling mill. Furthermore, it is not convenient to quickly replace the scraper, resulting in poor cleaning effect and low practicality after prolonged use. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a support roller cleaning device, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is: a support roller cleaning device, including a sizing machine base and a support roller body rotatably mounted on the inner surface of the sizing machine base. A mounting plate and a mounting frame are fixedly mounted on one end of the sizing machine base near the support roller body. A cylinder is fixedly mounted on the end of the mounting plate near the sizing machine base. A connecting sleeve is rotatably mounted on the output shaft of the cylinder. A fixing column is fixedly mounted on the other end of the mounting frame away from the sizing machine base. A surface cleaning component and a side cleaning component are provided on the outer surface of the fixing column away from the center line.

[0006] The surface cleaning assembly includes a mounting sleeve, a positioning plate, and an extension plate. The inner surface of the mounting sleeve is provided with a scraping plate that contacts the support roller body.

[0007] The side cleaning component includes a second mounting sleeve, the inner surface of which is provided with a second scraper that is longer than the first scraper, and the second scraper is in contact with the side of the support roller body.

[0008] Preferably, the mounting sleeve has a slot located away from the positioning plate and on the vertical line of the support roller body, and a scraper is inserted into the inner surface of the slot.

[0009] With the above technical solution, slot 1 is opened in the mounting sleeve 1 away from the positioning plate and located on the vertical line of the support roll body, so that scraper 1 can be inserted into slot 1 and contact the surface of the support roll body. This facilitates the installation and replacement of scraper 1. When scraper 1 is worn, it can be directly removed from slot 1 and replaced, ensuring that the cleaning effect on the surface of the support roll body is always good, ensuring that it can effectively clean the surface of the support roll body, prevent the roll coolant from remaining on the support roll, and prevent the coolant from entering the mill exit edge.

[0010] Preferably, the outer surface of the mounting sleeve is provided with a positioning groove, and the inner surface of the positioning groove is threaded with a positioning bolt, which passes through the positioning groove and the scraping plate.

[0011] With the above technical solution, the positioning groove is formed on the outer surface of the mounting sleeve, and the positioning bolt is threaded into the positioning groove and passes through the scraper plate. This design can firmly fix the scraper plate to the mounting sleeve. During the rotation of the support roller body, the scraper plate will not loosen or shift due to vibration or other external forces, and will continuously and stably clean the surface of the support roller body.

[0012] Preferably, a connecting sleeve is fixedly installed at one end of the extension plate near the cylinder, and the connecting sleeve is adapted to the cylinder output shaft.

[0013] With the above technical solution, a connecting sleeve is fixed to one end of the extension plate. The connecting sleeve is adapted to the cylinder output shaft, enabling the surface cleaning component to move in conjunction with the cylinder. When the cylinder is working, the connecting sleeve can drive the extension plate and the entire surface cleaning component to rotate, thus achieving angle adjustment.

[0014] Preferably, a positioning plate is fixedly installed at one end of the mounting sleeve, and the positioning plate is adapted to the mounting sleeve.

[0015] Through the above technical solution, the positioning plate is fixed to one end of the mounting sleeve and is adapted to it. The positioning plate plays the role of positioning and strengthening the structure. When installing components such as the scraper, the positioning plate can help determine the installation position and improve the installation accuracy.

[0016] Preferably, the outer surface of the mounting sleeve is provided with an extension block, the inner surface of the extension block is provided with a slot, and a scraping plate is inserted and installed on the inner surface of the slot.

[0017] With the above technical solution, the extension block is set on the outer surface of the mounting sleeve 2, and the slot 2 inside it is used to insert the scraper 2, which facilitates the installation and replacement of the scraper 2. When the scraper 2 is worn, it can be quickly removed from the slot 2 and replaced with a new scraper 2, ensuring the cleaning effect of the side cleaning component on the side of the support roller body.

[0018] Preferably, two identical side cleaning components are provided, and the two side cleaning components are symmetrically distributed about the center line of the support roller body.

[0019] With the above technical solution, the two side cleaning components are symmetrically distributed about the center line of the support roll body, which can clean both sides of the support roll body at the same time, ensuring the uniformity of cleaning on both sides of the support roll body, preventing coolant residue from being left uncleaned on one side and affecting the normal operation of the rolling mill, and improving the overall cleaning effect of the cleaning device.

[0020] Compared with the prior art, the present invention provides a support roller cleaning device, which has the following beneficial effects:

[0021] 1. This support roll cleaning device features a multi-angle, multi-part cleaning design. The surface cleaning component and the side cleaning component work together to thoroughly clean the coolant and other impurities on the surface and sides of the support roll body, ensuring cleaning effectiveness, preventing coolant from entering the mill exit edge, and improving the stability of mill operation.

[0022] 2. The support roller cleaning device has slot one and slot two for easy installation and replacement of scraper one and scraper two, respectively. When the scraper is worn, it can be quickly replaced, reducing maintenance costs. It can also prevent scraper one and scraper two from becoming less effective after long-term use, thus improving its practicality.

[0023] 3. The support roller cleaning device uses a cylinder to drive the surface cleaning components to rotate via a connecting sleeve to achieve angle adjustment. This allows it to flexibly adapt to the cleaning needs of different positions on the support roller body, improving the comprehensiveness and accuracy of cleaning. Attached Figure Description

[0031] 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.

[0032] Example 1: As Figure 1-6 As shown, the present invention provides a support roller cleaning device, including a slugging machine base 1 and a support roller body 2 rotatably mounted on the inner surface of the slugging machine base 1. A mounting plate 3 and a mounting frame 6 are fixedly mounted on one end of the slugging machine base 1 near the support roller body 2. A cylinder 4 is fixedly mounted on the end of the mounting plate 3 near the slugging machine base 1. A connecting sleeve 5 is rotatably mounted on the output shaft of the cylinder 4. A fixing column 7 is fixedly mounted on the other end of the mounting frame 6 away from the slugging machine base 1. A surface cleaning component 8 and a side cleaning component 9 are provided on the outer surface of the fixing column 7 away from the center line.

[0033] The surface cleaning assembly 8 includes a mounting sleeve 801, a positioning plate 802, and an extension plate 807. The inner surface of the mounting sleeve 801 is provided with a scraping plate 805 that contacts the support roller body 2.

[0034] The side cleaning component 9 includes a mounting sleeve 901, on the inner surface of which is a scraper 904 with a length longer than the scraper 805. The scraper 904 contacts the side of the support roller body 2.

[0035] Specifically, the mounting sleeve 801 has a slot 803 located away from the positioning plate 802 and on the vertical line of the support roll body 2. A scraper 805 is inserted and installed on the inner surface of the slot 803. The advantage is that the slot 803 is located away from the positioning plate 802 and on the vertical line of the support roll body 2, so that the scraper 805 can be inserted into the slot 803 and contact the surface of the support roll body 2. This facilitates the installation and replacement of the scraper 805. When the scraper 805 is worn, it can be directly removed from the slot 803 and replaced, ensuring that the cleaning effect on the surface of the support roll body 2 is always good. This ensures that it can effectively clean the surface of the support roll body 2, prevent the roll coolant from remaining on the support roll, and prevent the coolant from entering the mill exit edge.

[0036] Specifically, a positioning groove 804 is formed on the outer surface of the mounting sleeve 801, and a positioning bolt 806 is threadedly connected to the inner surface of the positioning groove 804. The positioning bolt 806 passes through the positioning groove 804 and the scraper plate 805. The advantage is that the positioning groove 804 is formed on the outer surface of the mounting sleeve 801, and the positioning bolt 806 is threaded into the positioning groove 804 and passes through the scraper plate 805. This design can firmly fix the scraper plate 805 to the mounting sleeve 801. During the rotation of the support roller body 2, the scraper plate 805 will not loosen or shift due to vibration or other external forces, and will continuously and stably clean the surface of the support roller body 2.

[0037] Specifically, a connecting sleeve 5 is fixedly installed at one end of the extension plate 807 near the cylinder 4. The connecting sleeve 5 is adapted to the output shaft of the cylinder 4. The advantage is that the connecting sleeve 5 fixed at one end of the extension plate 807 and the connecting sleeve 5 adapted to the output shaft of the cylinder 4 allow the surface cleaning component 8 to be linked with the cylinder 4. When the cylinder 4 is working, the connecting sleeve 5 can drive the extension plate 807 and the entire surface cleaning component 8 to rotate, thereby achieving angle adjustment.

[0038] Example 2: Figure 2-6 As shown, this is an improvement on the previous embodiment.

[0039] Specifically, a positioning plate 802 is fixedly installed at one end of the mounting sleeve 801. The positioning plate 802 is compatible with the mounting sleeve 801. The advantage is that the positioning plate 802 is fixed at one end of the mounting sleeve 801 and is compatible with it. The positioning plate 802 plays the role of positioning and strengthening the structure. When installing components such as the scraper plate 805, the positioning plate 802 can help determine the installation position and improve the installation accuracy.

[0040] Specifically, the outer surface of the mounting sleeve 901 is provided with an extension block 902, and the inner surface of the extension block 902 is provided with a slot 903. A scraper 904 is inserted into the inner surface of the slot 903. The advantage is that the extension block 902 is located on the outer surface of the mounting sleeve 901, and the slot 903 inside is used to insert the scraper 904, which facilitates the installation and replacement of the scraper 904. When the scraper 904 is worn, it can be quickly removed from the slot 903 and replaced with a new scraper 904, ensuring the cleaning effect of the side cleaning component 9 on the side of the support roller body 2.

[0041] Specifically, two identical side cleaning components 9 are provided, and the two side cleaning components 9 are symmetrically distributed about the center line of the support roll body 2. The advantage is that the two side cleaning components 9 are symmetrically distributed about the center line of the support roll body 2, which can clean both sides of the support roll body 2 at the same time, ensuring the uniformity of cleaning on both sides of the support roll body 2, preventing coolant residue from being left uncleaned on one side and thus affecting the normal operation of the rolling mill, and improving the overall cleaning effect of the cleaning device.

[0042] Working principle: During use, the support roller body 2 is rotatably installed inside the rolling mill base 1. An mounting plate 3 and a mounting bracket 6 are fixedly installed at one end near the support roller body 2. The cylinder 4 on the mounting plate 3 is connected to the extension plate 807 of the surface cleaning component 8 via a connecting sleeve 5 rotatably installed on the output shaft. The fixing post 7 on the mounting bracket 6 is used to install the surface cleaning component 8 and the side cleaning component 9. In the surface cleaning component 8, the slot 803 on the mounting sleeve 801 facilitates the installation and replacement of the scraper 805. The positioning groove 804 and the positioning bolt 806 firmly fix the scraper 805. The positioning plate 802 assists in installation and reinforces the structure. For stability, when cylinder 4 is working, it drives extension plate 807 and the entire surface cleaning assembly 8 to rotate through connecting sleeve 5, thereby achieving angle adjustment. This allows scraper 805 to continuously adhere to the surface of the support roller body 2 for cleaning, effectively removing impurities such as coolant. The slot 903 in the extension block 902 outside the mounting sleeve 901 of the side cleaning assembly 9 facilitates the installation and replacement of scraper 904. The two side cleaning assemblies 9 are symmetrically distributed about the center line of the support roller body 2. The scraper 904 is longer than scraper 805, allowing simultaneous cleaning of both sides of the support roller body 2, ensuring that impurities such as coolant on the sides are effectively removed.

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