Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and in particular to a cleaning roller device for rolling metal strip. Background Technology

[0002] During the rolling process, metal strip often accumulates impurities such as metal shavings and oxide particles. If these are not cleaned in time, they will directly affect the rolling accuracy and surface quality. Traditional cleaning techniques often use a combination of fixed brush rollers and dust collection devices. The brush rollers remove the debris by rotating, and the debris is then collected using negative pressure adsorption.

[0003] For example, Chinese Patent CN216324211U discloses a cleaning roller for precision rolling of brass strip. By opening adsorption ports on the surface of the cleaning roller, it can collect debris while cleaning the copper strip. However, the above device has the following technical problems: because the adsorption occurs near the bottom of the cleaning roller, it is difficult to form a vacuum, resulting in low adsorption pressure. This causes some debris to fall and accumulate on the lower surface of the cleaning roller during cleaning, affecting the cleaning effect. Furthermore, existing technologies mostly use a single-sided cleaning roller structure, requiring multiple operations for double-sided cleaning.

[0004] Therefore, there is an urgent need for an integrated and efficient solution for double-sided cleaning and simultaneous debris collection. Utility Model Content

[0005] To address the problems of incomplete debris removal, low collection efficiency, and easy accumulation in existing technologies, this utility model provides a novel cleaning roller device for metal strip processing. By setting a first dust collection hood and a second dust collection hood in the debris cleaning mechanism, the debris falls into the interior of the first dust collection hood and the second dust collection hood when the first cleaning roller and the second cleaning roller clean the copper strip, thereby avoiding the accumulation of debris.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A cleaning roller device for metal strip processing includes a bottom fixed frame, a cleaning side bracket fixed on the bottom fixed frame, a tension roller, a support roller, two sets of debris cleaning mechanisms, and a debris collection mechanism. The debris cleaning mechanism is integrated inside the cleaning side bracket. Each set of debris cleaning mechanisms is arranged opposite to the tension roller and the support roller. The debris cleaning mechanism includes a transmission component, a first cleaning component, and a second cleaning component. The first cleaning component includes a first dust collection cover, a first cleaning roller, and a first auxiliary contact roller. The second cleaning component includes a second dust collection cover, a second cleaning roller, and a second auxiliary contact roller. The first cleaning roller and the second cleaning roller are nested inside the first dust collection cover and the second dust collection cover, respectively. The first cleaning roller and the second cleaning roller rotate synchronously in opposite directions through the transmission component. The first auxiliary contact roller and the second auxiliary contact roller are rotatably connected to the two ends of the first dust collection cover and the second dust collection cover, respectively. The debris collection mechanism includes a debris collection box, a filter component disposed in the debris collection box (19), and a dust suction component. The debris collection mechanism is connected to the first dust collection cover and the second dust collection cover through a debris collection pipe.

[0008] Furthermore, the transmission assembly includes a transmission rod, a driven rod, a transmission pulley, a driven pulley, and a power belt. One end of the transmission rod is connected to the output end of the servo motor, and the other end is connected to the transmission pulley. The driven rod is driven to rotate through the power belt and the driven pulley. The transmission rod is coaxially fixed inside the first cleaning roller, and the driven rod is coaxially fixed inside the second cleaning roller.

[0009] Furthermore, the servo motor is fixedly mounted on the outer surface of the cleaning side bracket.

[0010] Furthermore, the first cleaning roller is located directly below the tension roller, and the second cleaning roller is located directly below the idler roller.

[0011] Furthermore, the outer periphery of the first and second cleaning rollers is wrapped with bristles or a flexible scraper.

[0012] Furthermore, the dust collection assembly includes an exhaust pipe connected to the outer side of the debris collection box and an air pump disposed in the middle of the exhaust pipe.

[0013] Furthermore, the filter assembly includes a guide rail, a filter screen, and a handle on the outside of the filter screen. The guide rail is symmetrically arranged on both sides of the inner wall of the debris collection box, and the filter screen is slidably connected to the guide rail.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The cleaning roller device for metal strip processing provided by this utility model forms a three-point clamping structure with the auxiliary clamping roller, cleaning roller, and tension roller or support roller, which can maintain the tension of the metal strip and ensure full contact between the cleaning roller and the strip surface; the double-sided synchronous cleaning mechanism forms a continuous cleaning path, which significantly improves the cleaning efficiency; the debris is collected by negative pressure at the far end of the debris cleaning mechanism through the collection pipe, which can avoid debris accumulation; the debris collection mechanism is equipped with a pull-out filter screen for easy maintenance.

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0023] like Figure 1As shown, the cleaning roller device includes a bottom fixed frame 1, a cleaning side support 2 vertically fixed thereon, a tension roller 3, a support roller 4, a debris cleaning mechanism 5, and a debris collection mechanism 6. The debris cleaning mechanism 5 is integrated in the middle of the cleaning side support 2, and its bottom is connected to the debris collection mechanism 6. The copper strip passes sequentially through the first dust collection hood 9, the support roller 4, and the second dust collection hood 25 to form a continuous cleaning path.

[0024] like Figure 1 and 3 As shown, the debris cleaning mechanism 5 includes a transmission assembly, a first cleaning assembly, a transmission assembly, and a second cleaning assembly. A servo motor 7 is fixed to the outside of the cleaning side bracket 2, and its output end is connected to a transmission rod 8. The transmission rod 8 passes through the cleaning side bracket 2 and is supported by bearings. One end of the transmission rod 8 is connected to the output end of the servo motor 7, and the other end is fixed to a transmission pulley 13. Power transmission is achieved by connecting the driven pulley 14 at the end of the driven rod 12 via a power output belt 15. A first cleaning roller 10 is coaxially fixed to the transmission rod 8, and a second cleaning roller 16 is coaxially fixed to the driven rod 12. The first cleaning roller 10 in the first cleaning assembly is powered by the servo motor 7 via the transmission rod 8, while the second cleaning roller 16 in the second cleaning assembly rotates synchronously in opposite directions via the transmission assembly consisting of the transmission pulley 13, the driven pulley 14, and the power output belt 15.

[0025] like Figure 2 As shown, the first cleaning assembly includes a first dust collection cover 9, a first cleaning roller 10, and a first auxiliary contact roller 11. The second cleaning assembly is disposed opposite to the support roller 3 below. The first cleaning roller 10 is nested inside the first dust collection cover 9. The two ends of the first dust collection cover 9 are connected to the freely rotatable first auxiliary contact roller 11 via bearings to ensure close contact between the copper strip and the cleaning roller. The second cleaning assembly is disposed opposite to the support roller 3 below. The second cleaning assembly includes a second dust collection cover 25, a second cleaning roller 16, and a second auxiliary contact roller 17. The second cleaning roller 16 is nested inside the second dust collection cover 25. The two ends of the second dust collection cover 25 are connected to the freely rotatable second auxiliary contact roller 11 via bearings to ensure close contact between the copper strip and the cleaning roller. The outer periphery of the first and second cleaning rollers is wrapped with bristles or a flexible scraper. The first auxiliary contact roller 11 and the second auxiliary contact roller 17 are distributed at both ends of each collection cover by a rotatable connection, forming a three-point positioning and clamping structure during the movement of the copper strip.

[0026] like Figure 4 and 5As shown, the debris collection mechanism 6 includes a debris collection pipe 18, a debris collection box 19, and a filter assembly disposed within the debris collection box 19. The debris collection pipe 18 is a Y-shaped branched pipe, connecting to the bottom of the first dust collection hood 9 and the bottom of the second dust collection hood 25, respectively, collecting debris into the debris collection box 19. An air pump 21 draws gas from the collection box 19 through an exhaust pipe 20, creating a negative pressure to accelerate the suction of debris along the collection pipe 18; the inner wall of the collection box 19 is provided with symmetrical guide rails 22, and the filter screen 23 is pulled along the guide rails 22 via a handle 24. Debris is retained on the surface of the filter screen 23, and the gas is discharged through the exhaust pipe 20.

[0027] When using this utility model device, one end of the copper strip is inserted between the tension roller 3 and the first dust collection hood 9 from one side. After the copper strip enters, the first auxiliary pressing roller 11 and the first cleaning roller 10 are in close contact with the surface of the copper strip. After the copper strip exits from the other side of the first dust collection hood 9, it is guided by the support roller 4 and then inserted into the second dust collection hood 25 from the end away from the first dust collection hood 9. At this time, the servo motor 7 is turned on. The servo motor 7 drives the transmission rod 8 to rotate, and the transmission rod 8 drives the first cleaning roller 10 to rotate and clean the upper surface of the copper strip. At the same time, the driven rod 12 and the second cleaning roller 16 are driven to rotate in the opposite direction through the belt drive to clean the lower surface of the copper strip. The debris generated during cleaning falls into the collection hood under the action of gravity and the negative pressure generated by the air pump 21 and enters the debris collection box 19 through the debris collection pipe 18. The filter screen 23 intercepts the debris. When the filter screen 23 is full of debris, the operator can pull out the filter screen 23 along the guide rail 22 by the handle 24 to complete the cleaning and maintenance.

[0028] This utility model allows the copper strip to complete double-sided cleaning in a single pass, with a debris collection rate of ≥95%. The pull-out filter design shortens maintenance time and improves the overall operating efficiency of the cleaning equipment.

[0029] The embodiments described above are merely some preferred embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort should fall within the protection scope of this utility model.
