Description

Technical Field

[0001] This utility model relates to the field of sheet metal descaling technology, and more specifically to a continuous descaling device for metal sheets based on a double-roller structure. Background Technology

[0002] During the cold rolling process of metal sheets, if there is oxide scale on the surface, it will be pressed into the surface of the sheet under the rolling force, forming defects such as pits and pinholes, which seriously affect the flatness and smoothness of the sheet. Descaling, on the other hand, yields a smooth and flat surface, meeting the high surface quality requirements of subsequent applications such as automobile manufacturing and home appliance panels. A continuous descaling device for metal sheets is a device used to remove oxide scale from the surface of metal sheets. The wire brush or scraper of the mechanical descaling device moves relative to the surface of the metal sheet under power, scraping or brushing off the oxide scale through friction and mechanical force. The bristles of the wire brush or the cutting edge of the scraper make close contact with the oxide scale, gradually abrading and scraping it away, exposing the clean metal body on the surface of the metal sheet.

[0003] For example, in the prior art disclosure number CN215659538U, a surface descaling device for seamless steel pipes is described. When the rotating motor is started, it drives the rotating wheel to rotate. The rotation of the rotating wheel drives the first linkage wheel to rotate through the second transmission belt. When the first linkage wheel rotates, it drives the first rotating shaft to rotate. When the first rotating shaft rotates, it drives the abrasive belt to rotate. When the abrasive belt rotates, it processes the outer wall of the steel pipe. The worker holds the handle to descal the steel pipe.

[0004] However, the existing technology described above still has the following problems when in use: during the descaling process, the oxide scale on the metal sheet easily spreads everywhere, polluting the surrounding working environment and seriously affecting the health of workers. Based on this, the present invention provides a continuous descaling device for metal sheets based on a double-roller structure with good dust removal effect. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides a continuous descaling device for metal sheets based on a double-roller structure. The device supports the stable conveying of the metal sheet through a limiting plate and limiting rollers. When the metal sheet passes between two wire brush rollers, the two wire brush rollers scrape off the oxide scale on the surface of the metal sheet, thus achieving continuous descaling. A vacuum cleaner is used for continuous suction, which can collect the scraped oxide scale to a certain extent and prevent the oxide scale from scattering everywhere and affecting the working environment, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a continuous descaling device for metal sheets based on a double-roller structure, comprising a processing box, wherein two vertically distributed wire brush rollers are provided inside the processing box, and mounting frames are fixedly provided on the outer walls of the two wire brush rollers. Electric push rods are fixedly provided on the opposite side of the two mounting frames, and the electric push rods are fixed to the processing box for adjusting the height of the mounting frames. A feed inlet is provided on one side of the processing box, and a discharge outlet is provided on the other side of the processing box. Two vertically distributed scrapers are fixedly provided on the inner wall of the discharge outlet, and a dust suction mechanism is fixedly provided at the bottom of the processing box for sucking up debris inside the processing box.

[0007] In a preferred embodiment, two front-to-back limiting plates are fixedly installed inside the processing box, and limiting rollers are provided above and below the two limiting plates to improve the stability of the metal sheet.

[0008] In a preferred embodiment, the dust collection mechanism includes a vacuum cleaner, which is detachably fixed to the bottom of the processing box. The vacuum cleaner is connected to the inside of the processing box through a suction pipe, and the vacuum cleaner can collect oxide scale inside the processing box, making it convenient to collect oxide scale.

[0009] In a preferred embodiment, a support frame is fixedly provided at the bottom of the processing box, and baffles are detachably connected to both the front and rear sides of the processing box. A tempered glass window is fixedly provided on the baffle located at the front of the processing box, and the tempered glass window facilitates the staff to view the inside of the processing box.

[0010] In a preferred embodiment, two air outlets are fixedly provided on the inner wall of the baffle located at the rear of the processing box, and an air pump is fixedly provided on the top of the processing box. The air pump is connected to the two air outlets through a three-way pipe. The air pump continuously supplies air into the two air outlets. The air blowing from the air outlets can blow the oxide scale on the surface of the metal plate toward the rear of the processing box, thereby improving the collection efficiency of oxide scale.

[0011] In a preferred embodiment, a motor is fixedly inserted through the rear end of each of the two mounting brackets. The front end of the motor output shaft passes through the mounting bracket and is fixed to the rear end of the wire brush roller. The motor is located inside the tempered glass window, and the wire brush roller is automatically rotated by the motor, thereby improving the descaling effect.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model supports the stable conveying of metal plates through limiting plates and limiting rollers. When passing between two wire brush rollers, the two wire brush rollers scrape off the oxide scale on the surface of the metal plate, playing a continuous descaling role. A vacuum cleaner is used to continuously suck up the scraped oxide scale, which can collect the scraped oxide scale to a certain extent and prevent the oxide scale from scattering everywhere and affecting the working environment.

[0014] 2. By continuously supplying air into the two air outlets through the air pump, the oxide scale on the surface of the metal sheet can be blown off the limiting plate and placed below the metal sheet. This can improve the collection efficiency of oxide scale to a certain extent. Furthermore, the scraper can clean the oxide scale on the surface of the metal sheet, which facilitates the improvement of the subsequent processing efficiency of the metal sheet.

[0023] Refer to the instruction manual appendix Figures 1-5 This utility model provides a continuous descaling device for metal plates based on a double roller structure, including a processing box 1. The processing box 1 is provided with two vertically distributed wire brush rollers 2. The outer walls of the two wire brush rollers 2 are fixedly provided with mounting brackets 3. The rear ends of the two mounting brackets 3 are fixedly connected to a motor 16. The front end of the output shaft of the motor 16 passes through the mounting bracket 3 and is fixed to the rear end of the wire brush roller 2.

[0024] Furthermore, electric push rods 4 are fixedly installed on the opposite sides of the two mounting brackets 3. The electric push rods 4 are fixed to the processing box 1 and are used to adjust the height of the mounting brackets 3. A feed port 5 is opened on one side of the processing box 1, and a discharge port 6 is opened on the other side of the processing box 1. Two scrapers 7 distributed vertically are fixedly installed on the inner wall of the discharge port 6.

[0025] The bottom of the processing box 1 is fixedly equipped with a dust collection mechanism 8 for sucking up debris inside the processing box 1. Specifically, the dust collection mechanism 8 includes a vacuum cleaner 801, which is detachably fixed to the bottom of the processing box 1. The vacuum cleaner 801 is connected to the inside of the processing box 1 through a suction pipe 802. The vacuum cleaner 801 can collect oxide scale inside the processing box 1, making it convenient to collect oxide scale.

[0026] The processing box 1 is fixedly equipped with two front-to-back limiting plates 9. Limiting rollers 10 are provided above and below the two limiting plates 9 to improve the stability of the metal sheet. A support frame 11 is fixedly provided at the bottom of the processing box 1. Baffles 12 can be detachably connected to both the front and rear sides of the processing box 1. A tempered glass window 13 is fixedly provided on the baffle 12 located at the front of the processing box 1. The tempered glass window 13 is provided to facilitate the staff to view the inside of the processing box 1. The motor 16 is located inside the tempered glass window 13 to avoid the motor 16 affecting the lifting and lowering of the mounting frame 3.

[0027] In actual use, the operator inserts one end of the metal sheet into the feed port 5 on the left side of the processing box 1. After being limited by the upper and lower limit rollers 10, the metal sheet can be stably conveyed between the two wire brush rollers 2. The electric push rod 4 drives the mounting frame 3 to rise and fall, thereby adjusting the distance between the wire brush rollers 2 and the metal sheet. With the help of the wire brush rollers 2 in the two mounting frames 3, the oxide scale on the surface of the metal sheet can be scraped off, which plays a descaling role. After descaling, the metal sheet continues to move and is removed from the discharge port 6, thus realizing continuous descaling. During the descaling process, the vacuum cleaner 801 in the dust collection mechanism 8 continuously sucks up the dust, which can collect the scraped oxide scale to a certain extent and prevent the oxide scale from spreading everywhere and affecting the working environment. At the same time, the two scrapers 7 on the inner wall of the discharge port 6 can scrape off the oxide scale on the surface of the metal sheet, thereby reducing the oxide scale on the surface of the metal sheet to a certain extent.

[0028] Refer to the instruction manual appendix Figures 1-5 Two air outlets 14 are fixedly installed on the inner wall of the baffle 12 located behind the processing box 1. An air pump 15 is fixedly installed on the top of the processing box 1. The air pump 15 is connected to the two air outlets 14 through a three-way pipe.

[0029] Air is continuously pumped into the two air outlets 14 by the air pump 15 on the processing box 1. The air blown from the air outlets 14 can blow the oxide scale on the surface of the metal plate to the rear of the processing box 1, thereby improving the collection efficiency of the oxide scale.
