Technical Field

[0001] The utility model relates to strip steel processing equipment, in particular to a closed strip steel polishing device. Background Art

[0002] Strip steel is a narrow and long steel plate. It is widely used in the manufacture of cold-rolled products, hot-rolled products, electrical steel, sheet metal parts, etc. It is also widely used in the automotive, shipbuilding, construction, metallurgy and other industries.

[0003] After rolling and heat treatment, in order to improve the appearance quality, the strip steel needs to be polished to remove the particles, scale and defects on the surface, so that the surface becomes smooth and flat. Generally, the polishing equipment is exposed to the air. During polishing, impurities on the surface of the strip steel will splash along with the grinding of the grinding equipment, which is not only easy to injure the operator, but also more laborious to clean. Therefore, we need a strip steel polishing device that can effectively prevent impurities from splashing. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the attached embodiment of the present utility model Figure 1-6 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example:

[0024] like Figures 1 to 6 As shown, the utility model discloses a closed type steel strip polishing device, comprising an operating table 1, on which a mounting plate 19 is fixedly mounted, on which a plurality of closed boxes 2 are fixedly connected, on which a movable door 3 is hinged, and on the sides of the closed box 2, openings 4 are provided for the steel strip to enter and exit the closed box 2, a plurality of polishing wheels 5 for polishing the steel strip are fixedly mounted on the mounting plate 19 in the closed box 2, a transmission mechanism for driving the polishing wheel 5 to rotate is provided on the mounting plate 19, a lower through pipe 6 is fixedly connected to the lower end of the closed box 2, and an extraction mechanism is provided at the lower end of the lower through pipe 6.

[0025] Among them, the transmission mechanism includes a servo motor 7, a rotating gear 8 and a plurality of transmission gears 9. The specific structure of the transmission mechanism is: the servo motor 7 is fixedly connected to the upper end of the closed box 2, the output shaft of the servo motor 7 passes through the mounting plate 19, the rotating gear 8 is fixedly connected to the output shaft of the servo motor 7, and the transmission gears 9 are respectively fixedly connected to the rotating shafts of each polishing wheel 5, and a synchronous belt 10 is meshed and connected between the rotating gear 8 and each transmission gear 9; through the above structure, the polishing wheel 5 is driven to rotate, so that the upper and lower surfaces of the strip are grinded and polished.

[0026] Furthermore, in order to ensure that the synchronous belt 10 can be closely attached to the gear teeth of the transmission gear 9, the mounting plate 19 is provided with a pressure roller 11 which is rotatably arranged between the transmission gear 9 and the rotating gear 8, and the pressure roller 11 is pressed on the outer surface of the synchronous belt 10. The pressure roller 11 squeezes the synchronous belt 10 toward the middle, thereby ensuring that the synchronous belt 10 can be closely attached to the gear teeth of the transmission gear 9, and ensuring that the transmission gear 9 in this embodiment can achieve synchronous rotation when the servo motor 7 is working.

[0027] Furthermore, the extraction mechanism includes an extraction pipe 12, an air pump 13 and a collection box 14. The specific structure of the extraction mechanism is: the extraction pipe 12 is fixedly connected to the lower end of the down pipe 6, the air pump 13 is fixedly connected to the extraction pipe 12, and the collection box 14 is fixedly connected to the lower end of the air pump 13; after the polishing wheel 5 grinds and removes the impurities on the surface of the strip, the air pump 13 sucks the impurities and dust from the closed box 2 into the collection box 14 through the extraction pipe 12; and, in order to ensure the air pressure balance in the extraction mechanism and the closed box 2, an air outlet 15 is opened at the lower end of the collection box 14, so that the air extracted by the air pump 13 can enter and disperse through the air outlet 15. At the same time, in order to prevent the collected impurities from being flushed out of the collection box 14, the collection box 14 is fixedly connected to a fine-pore filter 16 at the air outlet 15 by a screw. When the storage capacity of impurities in the collection box 14 reaches saturation, the fine-pore filter 16 can be removed to clean the impurities in the collection box 14.

[0028] The working principle of the utility model is as follows: the operator makes the steel strip pass through the through port 4 into the closed box 2. When the steel strip passes between the polishing wheels 5, the polishing wheels 5 grind and polish the upper and lower surfaces of the steel strip, thereby removing impurities on the surface of the steel strip. The fallen impurities fall downward into the lower through pipe 6 and pass through the extraction pipe 12, and are sucked into the collection box 14 by the vacuum pump 13. During the entire polishing process, the steel strip is in a relatively closed state, and the removed impurities will be sucked into the collection box 14 by the vacuum pump 13 and will not splash into the air, which can ensure that the operator will not be harmed by the splashing impurities and facilitate the collection and cleaning of impurities.

[0029] In addition, in order to facilitate the operator to observe the situation inside the closed box 2 when polishing the steel strip, an observation window 17 is fixedly connected to the upper end of the movable door 3 (the glass of the observation window 17 is high borosilicate glass, which is stable in nature, high in strength, and will not be easily damaged), and a number of lighting lamps 18 are fixedly connected to the inner side of the movable door 3 for illuminating the interior of the closed box 2. The above structure enables the operator to observe the situation of the steel strip after it enters the closed box 2, so as to better control the polishing effect of the steel strip.

[0030] It should also be pointed out that the terms used in the present invention, such as "front", "rear", "vertical", "horizontal", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
