[0021] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figure 1 An embodiment of the present invention provides an adsorbable brush roller, including a roller 1 and bristles 2 arranged on the surface of the roller 1, a magnetic attraction mechanism is arranged inside the roller 1, and an adsorption channel is arranged on the roller 1, and the adsorption channel connects the inner and outer spaces of the roller 1.

[0023] Preferably, the roller 1 is provided with a rotation drive mechanism for rotating it at a certain speed, including but not limited to being driven by a motor, etc. 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, the friction coefficient between the two, etc., in order to ensure that the roller 1 and the contacted part (steel coil, roller system or strip steel) have a certain relative motion speed, so that the iron oxide scale on the surface of the contacted part can be peeled off.

[0024] Preferably, the roller 1 is provided with a pressing drive mechanism, which can press the roller 1 against the surface of the contacted member, and the pressure is controllable, including but not limited to being driven by a hydraulic cylinder or a pneumatic cylinder.

[0025] The magnetic attraction mechanism can generate magnetic force, and under the adsorption effect of the magnetic force, the iron oxide scale and the like brushed off by the bristles 2 can be adsorbed. An adsorption space is formed in the roller 1, and the adsorption channel is connected to the adsorption space. The iron oxide scale can be adsorbed by the magnetic attraction mechanism after passing through the adsorption channel and the adsorption space in sequence.

[0026] Alternatively, if Figure 1 The magnetic attraction mechanism includes a magnetic rod 3, and two ends of the magnetic rod 3 are respectively connected to two ends of the roller 1.

[0027] Preferably, the magnetic rod 3 is coaxially arranged with the roller 1, so as to ensure the uniformity of the magnetic force at various locations around the roller 1 and ensure the adsorption and dust removal effect.

[0028] Preferably, the magnetic bar 3 can be removed from the roller 1 to facilitate the cleaning and recovery of adsorbed iron oxide and other substances. Figure 1 The roller 1 includes a cylinder 11 and two shaft heads 12 detachably assembled to the two ends of the cylinder 11, and the two ends of the magnetic bar 3 are detachably connected to the two shaft heads 12. The magnetic bar 3 and the shaft heads 12 are connected by threaded connection, etc.; the shaft heads 12 are connected to the cylinder 11. After the shaft heads 12 at both ends of the cylinder 11 are removed, the magnetic bar 3 can be taken out of the cylinder 11 for air cleaning or maintenance.

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

[0030] Among them, when an electromagnet is used, the working flexibility of the brush roller is relatively high. By controlling the operation of the magnetic suction mechanism, the brush roller can switch between multiple working modes such as bristles 2 only, bristles 2 + magnetic suction, etc.; moreover, by de-energizing the electromagnet, the adsorbed iron oxide scale can be easily removed.

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

[0032] The adsorption channel can be in the form of adsorption holes 10, that is, the adsorption channel includes a plurality of adsorption holes 10, and 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 oxidized iron scale on site.

[0033] Preferably, if Figure 2 The adsorption holes 10 are fan-shaped holes extending along the circumference of the roller 1. This design ensures that the adsorption operation can be continuously performed during the rotation of the roller 1, thereby improving the adsorption effect and efficiency of the oxidized iron scale.

[0034] More preferably, if Figure 2 , each of the adsorption holes 10 is distributed to form a plurality of adsorption rings, each of the adsorption rings is spaced in sequence along the axial direction of the roller, each adsorption ring includes a plurality of adsorption holes 10 distributed on the same cross section of the roller 1, and each of the adsorption holes 10 in two adjacent adsorption rings is 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 better matches the cleaning range of the bristles 2; 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, there is a line contact between the roller 1 and the contacted part, and the concentration of iron oxide powder near the contact line is relatively high. The distribution of the above-mentioned adsorption holes 10 can ensure that the adsorption function can cover the area near the contact line, thereby ensuring the iron oxide adsorption effect.

[0035] The adsorption holes 10 are preferably arranged away from the installation position of the bristles 2. For example, the adsorption holes 10 are arranged in the gaps between the bristles 2. This allows the iron oxide sheets acted upon by the bristles 2 to be magnetically adsorbed immediately.

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

[0037] Of course, a dust removal system can be further provided on the basis of the above-mentioned brush roller 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, and the rotary joint is connected to a vacuum suction pipe. Based on this structure, the effect of coupled dust removal by magnetic adsorption + vacuum adsorption can be achieved, which has a better effect on capturing iron oxide and can reduce the degree of dust flying; based on the vacuum adsorption effect, the flying dust can be directed through the adsorption channel, which is conducive to the capture of iron oxide and prevents the iron oxide from being deposited on the outer surface of the roller 1. Since the vacuum suction pipe is at the end of the roller 1, under the action of magnetic force, the iron oxide entering the roller 1 will be captured by the magnetic suction mechanism at the first time, which can reduce the iron oxide screening work at the vacuum suction end and facilitate the recycling of iron oxide.

[0039] In one of the embodiments, at least one end of the roller 1 is provided with an openable and closable compressed air pipe interface, and the adsorption channel can be cleaned by back-blowing with compressed air to ensure the working reliability of the brush roller.

[0040] In one embodiment, the adsorbable brush roller is further provided with a weight detection unit for detecting its weight. More specifically, the weight detection unit is used to detect the weight of the roller 1, and can be arranged on the brush roller bearing seat 4. On the one hand, after the brush roller has worked for a period of time and adsorbed a certain amount of iron oxide, the magnetic adsorption effect of the magnetic adsorption mechanism may be weakened. The weight detection unit can facilitate production personnel to clean and maintain the brush roller to ensure the working reliability of the brush roller; on the other hand, as the weight of the roller 1 increases, it can be checked whether to adjust the pressing pressure of the roller 1 according to the actual working conditions.

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

[0042] When the magnetic attraction mechanism adopts an electromagnet, the control power supply of the electromagnet is electrically connected to the above-mentioned controller, and the electromagnet can be controlled to be powered or de-powered by the controller;

[0043] When the vacuum suction pipe is configured, the vacuum suction device is electrically connected to the controller, and the controller can be used to control whether the vacuum suction device is working and the negative pressure level in the roller 1.

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