Description

Technical Field

[0001] This utility model belongs to the field of metallurgical equipment technology, specifically relating to an adsorption-type brush roller. Background Technology

[0002] Hot-rolled leveling or continuous strip steel production units typically have brush rollers installed at the uncoiler coil uncoiling point, strip steel transport channel, or dry leveler rolls to remove iron oxide scale from the surface of the strip steel or roll system, preventing the iron oxide scale from repeatedly rolling into the strip steel surface and affecting the surface quality of the strip steel.

[0003] Conventional brush rollers are equipped with dust hoods, which use negative air pressure to draw iron oxide scale into the pipeline and connect it to the dust removal system. However, due to limitations imposed by actual working conditions, the dust hoods cannot form a truly sealed space with the actual strip steel or roller system, resulting in larger gaps and limited dust removal efficiency.

[0021] The technical solutions in the embodiments of this utility model are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] like Figure 1 This utility model provides an adsorption-type brush roller, including a roller 1 and brush bristles 2 disposed on the surface of the roller 1. The roller 1 is provided with a magnetic attraction mechanism and an adsorption channel is provided on the roller 1, which connects the inner and outer spaces of the roller 1.

[0023] Preferably, the roller 1 is equipped with a rotary drive mechanism for rotating at a certain speed, including but not limited to driving it with a motor. The direction and speed of the roller 1 rotation are determined according to the actual production conditions, such as the specifications of the strip steel, the material of the bristles 2, and the coefficient of friction between them. The purpose is to ensure that the roller 1 and the contacted part (steel coil, roller system, or strip steel) have a certain relative speed, so as to peel off the iron oxide scale on the surface of the contacted part.

[0024] Preferably, the roller 1 is equipped with a pressing drive mechanism, which can press the roller 1 against the surface of the contacted part, and the pressure is controllable, including but not limited to using a hydraulic cylinder or a pneumatic cylinder for driving.

[0025] The aforementioned magnetic attraction mechanism generates magnetic force, which attracts iron oxide scale and other materials brushed off by the brush bristles 2. An adsorption space is formed inside the roller 1, and the aforementioned adsorption channel is connected to this adsorption space. The iron oxide scale can pass through the adsorption channel and the adsorption space sequentially before being attracted by the magnetic attraction mechanism.

[0026] Optionally, such as Figure 1 The magnetic attraction mechanism includes a magnetic rod 3, the two ends of which are respectively connected to the two ends of the roller 1.

[0027] Preferably, the magnetic rod 3 is coaxially arranged with the roller 1, which can ensure the uniformity of magnetic force in all directions of the roller 1 and ensure the adsorption and dust removal effect.

[0028] Preferably, the magnetic rod 3 can be removed from the roller 1 to facilitate the cleaning and recycling of adsorbed iron oxide scale and other substances. In one embodiment, such as Figure 1 The roller 1 includes a cylinder body 11 and two shaft heads 12 detachably mounted to both ends of the cylinder body 11. The magnetic rod 3 is detachably connected to both shaft heads 12 at both ends. The connection between the magnetic rod 3 and the shaft heads 12 includes, but is not limited to, threaded connections; the shaft heads 12 are, but are not limited to, fitted onto the cylinder body 11. After removing the shaft heads 12 from both ends of the cylinder body 11, the magnetic rod 3 can be removed from the cylinder body 11 for air intake cleaning or maintenance.

[0029] In one embodiment, the magnetic attraction mechanism uses a permanent magnet, for example, the magnetic rod 3 is made of a permanent magnetic material. In another embodiment, the magnetic attraction mechanism uses an electromagnet, for example, the magnetic rod 3 is an electromagnet rod. Accordingly, a rotary electrical connector can be provided at the end of the roller 1, and the electromagnet is electrically connected to the rotary electrical connector, which is used to connect an external controllable power supply.

[0030] Among them, when using an electromagnet, the brush roller has relatively high working flexibility. By controlling whether the magnetic attraction mechanism is working or not, the brush roller can switch between multiple working modes such as brushing only 2 bristles and brushing 2 + magnetic attraction. Moreover, when the electromagnet is de-energized, it is easier to remove the adsorbed iron oxide scale.

[0031] Whether it is a permanent magnet or an electromagnet, the iron oxide powder can be scraped off by scraping the workpiece. After cleaning, the magnetic attraction mechanism can be reinstalled into the roller 1 and can be put back into operation.

[0032] The above-mentioned adsorption channel can take the form of adsorption holes 10, that is, the adsorption channel includes multiple adsorption holes 10. The width and length of the adsorption holes 10 can be set according to the size of the roller 1 and the particle size of the iron oxide scale on site.

[0033] Preferably, such as Figure 2 The adsorption hole 10 is a fan-shaped hole extending circumferentially along the roller 1. This design ensures that the adsorption operation can be carried out continuously during the rotation of the roller 1, thereby improving the adsorption effect and efficiency of iron oxide scale.

[0034] More preferably, such as Figure 2 Each of the adsorption holes 10 is distributed to form multiple adsorption rings, which are sequentially spaced along the roller axial direction. Each adsorption ring includes multiple adsorption holes 10 distributed on the same cross-section of the roller 1, and the adsorption holes 10 in two adjacent adsorption rings are staggered in the circumferential direction of the roller 1. Based on this structure, on the one hand, the adsorption effect in the axial direction of the brush roller is guaranteed, which matches the cleaning range of the bristles 2 well; on the other hand, the staggered distribution of the adsorption holes 10 can ensure the continuity and reliability of adsorption in the axial direction of the brush roller; in addition, the contact between the roller 1 and the contacted part is a line contact, and the concentration of iron oxide powder near the contact line is relatively high. The above-mentioned distribution of adsorption holes 10 can ensure that the adsorption function can cover the area near the contact line, thereby ensuring the adsorption effect of iron oxide powder.

[0035] The aforementioned adsorption holes 10 should preferably avoid the installation position of the brush bristles 2. For example, the adsorption holes 10 can be set in the gaps in the arrangement of the brush bristles 2, so that the iron oxide scale acted upon by the brush bristles 2 can be magnetically adsorbed immediately.

[0036] In this embodiment, by setting a magnetic attraction mechanism inside the brush roller, the brushed iron oxide scale can be captured by the magnetic attraction mechanism through the adsorption channel under the action of magnetic force, thereby effectively improving the air quality at the work site, making it more operator-friendly and achieving clean rolling; the dust removal system with poor sealing performance can be eliminated, thereby reducing the space occupied by the equipment and the operating cost.

[0037] Of course, a dust removal system can also be added to the brush rollers mentioned above to further improve the on-site production environment.

[0038] In one embodiment, at least one end of the roller 1 is provided with a rotary joint, which is connected to a vacuum suction pipe. Based on this structure, a coupled dust removal effect of magnetic adsorption and vacuum adsorption can be achieved, resulting in better capture of iron oxide scale and reduced dust dispersion. Due to the vacuum adsorption effect, the flying dust can be directed through the adsorption channel, which is beneficial for capturing iron oxide scale and preventing it from depositing on the outer surface of the roller 1. Since the vacuum suction pipe is located at the end of the roller 1, under the action of magnetic force, the iron oxide scale entering the roller 1 is immediately captured by the magnetic attraction mechanism, reducing the iron oxide scale screening work at the vacuum suction end and facilitating the recycling of iron oxide scale.

[0039] In one embodiment, at least one end of the roller 1 is provided with an openable and closable compressed air pipe interface, which can be used to clean the adsorption channel by means of compressed air backflushing, so as to ensure the working reliability of the brush roller.

[0040] In one embodiment, the adsorption-type brush roller is further equipped with a weight detection unit for detecting its weight. More specifically, this weight detection unit is used to detect the weight of the roller 1 and can be mounted on the brush roller bearing seat 4. On the one hand, after the brush roller has been working for a period of time and has adsorbed a certain amount of iron oxide scale, the magnetic adsorption effect of the magnetic attraction mechanism may weaken. The aforementioned weight detection unit facilitates the cleaning and maintenance of the brush roller by production personnel, ensuring the reliability of the brush roller's operation. On the other hand, as the weight of the roller 1 increases, the pressing pressure of the roller 1 can be checked and adjusted according to the actual working conditions.

[0041] Accordingly, the brush roller is also equipped with a controller, which can be directly adopted from the central control console of the rolling workshop. The weight detection unit is electrically connected to the controller. The controller is used to determine whether to adjust the pressing pressure of roller 1 based on the detection information fed back by the weight detection unit, and to perform the corresponding operation.

[0042] When the magnetic attraction mechanism uses an electromagnet, the control power supply of the electromagnet is electrically connected to the controller mentioned above, and the controller can control the electromagnet to be energized or de-energized.

[0043] When a vacuum suction pipe is configured, the vacuum suction equipment is electrically connected to the controller mentioned above. The controller can control whether the vacuum suction equipment is working and the degree of negative pressure inside the roller 1.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
