Description

Technical Field

[0001] This utility model belongs to the field of guide and decontamination technology, and in particular relates to a self-cleaning guide assembly for rolling mills. Background Technology

[0002] Mill guides are auxiliary devices installed before and after the roll passes. They are core components used to guide the workpiece to enter and exit the roll passes accurately in a predetermined direction and state, ensuring the stability of the rolling process and the quality of the product.

[0003] Currently, impurities such as iron oxide scale, oil stains, and dust easily accumulate on the surface of rolling mill guide rolls, directly affecting rolling efficiency and product quality, increasing friction between the guide rolls and the rolled workpiece, accelerating wear on the guide roll surface, and even causing scratches or deformation.

[0004] To address the aforementioned issues, this application proposes a self-cleaning guide assembly for rolling mills. Utility Model Content

[0005] The purpose of this utility model is to provide a self-cleaning guide assembly for rolling mills, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a self-cleaning guide assembly for a rolling mill, including a fixed base, a support, and guide rollers inside it;

[0008] The cleaning unit is located on the outside of the support and has a bracket inside. The inner side of the bracket has an arc-shaped structure with an outwardly convex end face that fits against the side plate of the guide roller.

[0009] The bracket is also provided with an arc-shaped roller on the inner side and a densely protruding block on the outer side.

[0010] Furthermore, the bottom of the support is provided with a positioning hole for the positioning shaft at the bottom of the guide roller to pass through.

[0011] Furthermore, the bottom of the bracket is provided with a gear, and a square rod is provided above it to be inserted into the bottom of the positioning shaft.

[0012] Furthermore, the bottom of the arc-shaped roller is provided with a toothed disc that meshes with a gear.

[0013] Furthermore, the lower inner side of the bracket is provided with a bearing seat to rotatably mount the lower end of the arc-shaped roller.

[0014] Furthermore, the end of the side plate is provided with a scraper that fits against the guide roller and extends toward the side of the arc-shaped roller.

[0015] Furthermore, the side plate is provided with a side seat on its side, and a brush is provided on its inner side to remove dirt from the arc-shaped roller in real time.

[0016] This utility model has the following beneficial effects:

[0017] This invention uses an external cleaning unit to remove impurities from the surface of the guide roller during its rotation by a scraper, thereby keeping the surface in contact with the workpiece clean at all times. This avoids the situation where residual impurities increase frictional resistance and scratch the workpiece or roller body.

[0018] This invention utilizes the rotation of an arc-shaped roller to continuously scrape the surface of the support, thereby loosening or removing solidified impurities on the surface. Then, a scraper is used for secondary scraping to remove solid impurities from the roller surface, achieving a double cleaning and decontamination effect.

[0019] 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

[0036] 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.

[0037] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0038] Please see Figure 1-5 As shown, this utility model is a self-cleaning guide assembly for a rolling mill, including a fixed base 110, a support 120, and a guide roller 130 inside the support.

[0039] The cleaning unit 2 is located on the outside of the support 120 and has a bracket 210 inside. The inner side of the bracket 210 has a side plate 240 with an outwardly protruding arc structure that fits against the guide roller 130. The arc structure extends to the side of the arc roller 220 and has a protruding scraper 241, so as to scrape off the impurities on the surface of the guide roller 130 in real time when it rotates.

[0040] The inner side of the support 210 is also provided with an arc-shaped roller 220, and the outer side is densely protruding protrusions 222. In this way, when the guide roller 130 rotates, the circular protrusions 222 come into contact with the impurities, thereby creating a loosening effect and even scraping them off.

[0041] Preferably, the bottom of the support 120 is provided with a positioning hole 121 for the positioning shaft 131 at the bottom of the guide roller 130 to pass through, and the bottom of the positioning shaft 1311 is provided with a square hole.

[0042] Preferably, the bottom of the bracket 210 is provided with a gear 250, and a square rod is provided above it and inserted into the bottom of the positioning shaft 131. The bottom of the arc roller 220 is provided with a toothed disc 221 that meshes with the gear 250. Thus, the rotational force of the guide roller 130 is used to replace the rotating motor and other equipment to transmit the rotational driving force to the arc roller 220.

[0043] Preferably, the lower inner side of the bracket 210 is provided with a bearing 230 for rotatably mounting the lower end of the arc roller 220, which is used to support and limit the arc roller 220.

[0044] Preferably, the side plate 240 is provided with a side seat 260, and the inner side of the side seat 260 is provided with a brush 261 to remove dirt from the arc roller 220 in real time, thereby brushing off impurities and preventing them from returning to the guide roller 130.

[0045] It is understood that this utility model adds a decontamination component to the outside of the roller body and uses the rotation of the roller body to generate driving force, so that the decontamination component forms a dual decontamination of loosening and scraping, thereby achieving real-time cleaning treatment and keeping the contact surface between the roller body and the rolled piece clean at all times.

[0046] A specific application of the operation process of this embodiment is as follows: First, the bracket 210 is installed on the outer side of the support 120, and the square rod above the gear 250 is inserted into the bottom of the positioning shaft 131. Then, the rotation of the guide roller 130 drives the arc roller 220 to rotate through the meshing of the gear 250 and the gear plate 221. At this time, the outer side 222 of the arc roller 220 continuously scrapes the solidified impurities on the outer side of the guide roller 130, making them loose or fall off. Then, the impurities that have not fallen off are scraped off by the scraper 241 when they rotate to the area where the side plate 240 is located, thus forming a double cleaning effect. In addition, during the rotation of the arc roller 220, the brush 261 on the inner side of the side seat 260 brushes away the impurities on the outer side of the arc roller 220 in real time, so that the surface in contact with the guide roller 130 is always free of impurities, thereby preventing impurities from returning to the guide roller 130.
