Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing equipment technology, and in particular to a sheet metal straightening machine roller surface cleaning component. Background Technology

[0002] A sheet metal straightening machine is a device used to flatten uneven sheet metal. It typically includes multiple upper and lower pressure rollers arranged vertically, forming a straightening space between them. In use, the sheet metal is transferred to one end of the flattening space by a feeding mechanism. The upper and lower pressure rollers rotate in opposite directions under the drive of a drive mechanism. During the rotation, the upper and lower pressure rollers cooperate to gradually flatten the sheet metal and transfer it to the other end of the straightening space. The flattened sheet metal leaves the flattening space through a feeding mechanism, thus achieving the straightening operation of the sheet metal.

[0003] Existing sheet metal straightening machines apply pressure to the sheet metal when it comes into contact with the sheet metal surface using upper and lower pressure rollers to achieve the straightening operation. However, the straightening efficiency is low due to the limited number of upper and lower pressure rollers.

[0004] An existing patent (publication number: CN221414512U) discloses a sheet metal straightening machine. This utility model can better improve the efficiency of the sheet metal straightening machine in straightening sheets.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, the straightening rollers of existing sheet metal straightening machines are in constant contact with the sheet metal surface, making them prone to accumulating impurities such as metal shavings and oxide scale. Traditional cleaning methods often involve manual wiping after the machine is stopped, which is not only inefficient but also poses safety hazards. Furthermore, the cleaning process lacks a shavings collection and processing device, which can easily lead to secondary contamination of the straightening rollers by impurities. If the roller surface is not cleaned in time, the accumulation of impurities can cause scratches and indentations on the sheet metal surface, thus affecting the straightening quality of the sheet metal.

[0006] To address this, a roller surface cleaning component for a sheet metal straightening machine is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a roller surface cleaning component for a sheet metal straightening machine. This component addresses the problem that existing sheet metal straightening machines' straightening rollers, which are in long-term contact with the sheet metal surface, are prone to accumulating impurities such as metal shavings and oxide scale. Traditional cleaning methods often involve manual wiping after the machine is stopped, which is not only inefficient but also poses safety hazards. Furthermore, the lack of a debris collection and processing device during the cleaning process can easily lead to secondary contamination of the straightening rollers by impurities. If the roller surface is not cleaned in time, the accumulation of impurities can cause scratches and indentations on the sheet metal surface, thus affecting the straightening quality of the sheet metal.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A roller surface cleaning assembly for a sheet metal straightening machine includes a frame 1, a lower roller 2 disposed on the bottom side inside the frame 1, lifting adjustment blocks 3 disposed on both sides inside the frame 1, an upper roller 4 disposed on the inner side of the lifting adjustment blocks 3, and a cleaning mechanism 5 disposed on the inner side of both the frame 1 and the lifting adjustment blocks 3.

[0029] The cleaning mechanism 5 includes a cavity plate 51 located on the front side of the lower roller 2 and the rear side of the upper roller 4. The cavity plate 51 is respectively bolted to the left side of the machine frame 1 and the inner side of the left lifting adjustment block 3. A suction port 52 is provided at the bottom of the inner side of the cavity plate 51, and a slot 53 is provided at the top of the inner side of the cavity plate 51. An insert plate 54 is inserted into the slot 53. A rubber scraper 55 is provided at the bottom of the insert plate 54. The bottom of the front rubber scraper 55 contacts the front side of the lower roller 2, and the bottom of the rear rubber scraper 55 contacts the rear side of the upper roller 4. A suction bucket 56 is connected to the top of the cavity plate 51, and a suction pipe 57 is connected to the top of the suction bucket 56. A suction filter assembly 58 is connected to the right side of the suction pipe 57.

[0030] In this embodiment: By setting up a cleaning mechanism 5, when the board passes between the upper roller 4 and the lower roller 2, the cleaning mechanism 5, which is set inside the frame platform 1 and the lifting adjustment block 3, is started synchronously. The insert plate 54, which is inserted into the slot 53 of the cavity plate 51, carries a rubber scraper 55, which is in close contact with the front side of the lower roller 2 and the rear side of the upper roller 4 respectively. During the rotation of the roller group, the roller surfaces of the lower roller 2 and the upper roller 4 are scraped in real time, effectively removing impurities such as metal debris and oxide scale. At the same time, the suction filter assembly 58 is started synchronously to form a negative pressure. The scraped impurities enter through the suction port 52 at the bottom of the cavity plate 51, and are transported to the suction filter assembly 58 for filtration and collection through the suction bucket 56 and the suction pipe 57. This design realizes the synchronous operation of cleaning and recycling, which not only avoids the damage to the surface of the board caused by the accumulation of impurities, but also prevents secondary pollution through immediate treatment, ensuring that the roller surfaces of the lower roller 2 and the upper roller 4 are always kept clean, thereby significantly improving the straightening quality of the board and the production efficiency.

[0031] Specifically, such as Figure 4 As shown, the suction filter assembly 58 includes a stretch tube 581 connected to the right side of the suction tube 57, and a conduit 582 connected to the bottom of the right side of the stretch tube 581.

[0032] Specifically, such as Figure 4 As shown, a filter structure 583 is provided on the right side of the top of the frame 1, and the left side of the filter structure 583 is connected to the right side of the conduit 582.

[0033] Specifically, such as Figure 4As shown, an exhaust fan 584 is installed on the right side of the top of the frame 1. The absorption end of the exhaust fan 584 is connected to a connecting pipe 585, which is connected to the right side of the filter structure 583.

[0034] In this embodiment: by setting up the suction filter assembly 58, the suction fan 584 generates negative pressure after starting, driving the airflow to enter the stretching tube 581 through the suction port 52, suction bucket 56, and suction pipe 57 at the bottom of the cavity plate 51. The scraped impurities enter the filter structure 583 through the conduit 582 at the bottom right side of the stretching tube 581 with the airflow. During this process, the principle of negative pressure adsorption is used to immediately suck in the scraped impurities and transport them to the filter structure 583 for filtration and collection. This realizes full automation from roller surface cleaning to debris collection, avoiding secondary pollution caused by impurity accumulation or scattering. At the same time, the suction power ensures cleaning efficiency, making the removal of impurities from the roller surface more thorough and ensuring stable board straightening quality.

[0035] Specifically, such as Figure 5 As shown, the filter structure 583 includes a filter box 5831 located on the top right side of the frame 1. The left side of the filter box 5831 is connected to the right side of the conduit 582, and the right side of the filter box 5831 is connected to the left side of the connecting pipe 585. A box cover 5832 is bolted to the top of the filter box 5831.

[0036] Specifically, such as Figure 5 As shown, a metal filter screen 5833 and an activated carbon adsorption layer 5834 are respectively bolted to the bottom of the box cover 5832. Both the metal filter screen 5833 and the activated carbon adsorption layer 5834 are located inside the filter box 5831, and the activated carbon adsorption layer 5834 is located to the right of the metal filter screen 5833.

[0037] In this embodiment: by setting up a filter structure 583, after impurities enter the filter box 5831, they first pass through the metal filter screen 5833 to intercept larger particles of impurities, and then pass through the activated carbon adsorption layer 5834 to purify the air, adsorb fine dust and oil stains, and achieve gas-solid separation. The detachable design of the box cover 5832 makes it easy to clean the metal filter screen 5833 and the activated carbon adsorption layer 5834 regularly to maintain filtration efficiency.

[0038] Specifically, such as Figure 4 As shown, the top and bottom of the stretch tube 581 are made of metal tubes, and the middle connecting part is made of a spiral stretchable hose.

[0039] Specifically, such as Figure 1 As shown, a PLC controller 6 is installed on the left side of the top of the frame 1, and the PLC controller 6 is electrically connected to the suction fan 584.

[0040] In this embodiment: by using a spiral stretchable hose combined with a metal tube, the stretchable tube 581 is used, which not only ensures structural strength, but also can adaptively adjust with the rise and fall of the upper roller 4, avoiding the decrease in suction due to pipe twisting, and ensuring the stable operation of the entire cleaning system. The PLC controller 6 automatically starts and stops the suction fan 584 according to the preset program, which is convenient for use.

[0041] Working principle: During the use of the roller surface cleaning component of the sheet metal straightening machine, firstly, when the sheet metal is straightened between the upper roller 4 and the lower roller 2, the PLC controller 6 starts the suction fan 584 according to the preset program, simultaneously triggering the cleaning process. At this time, the insert plate 54, which is inserted into the slot 53 of the cavity plate 51 and carries the rubber scraper 55, makes close contact with the front side of the lower roller 2 and the rear side of the upper roller 4 respectively. During the rotation of the lower roller 2 and the upper roller 4, the roller surface is scraped in real time to remove impurities such as metal debris and oxide scale. At the same time, the negative pressure generated by the suction fan 584 causes the airflow to enter the stretching tube 581 through the suction port 52, suction bucket 56, and suction pipe 57 at the bottom of the cavity plate 51. The scraped impurities are carried by the airflow through the bottom right side of the stretching tube 581. The conduit 582 enters the filter box 5831. Impurities in the filter box 5831 first pass through the metal filter screen 5833 to intercept larger particles, and then pass through the activated carbon adsorption layer 5834 to purify the air, adsorbing fine dust and oil stains, thus achieving gas-solid separation. During this process, the spiral stretchable hose structure of the stretch tube 581 adaptively adjusts with the height change of the upper roller 4 driven by the lifting adjustment block 3, avoiding pipe twisting that would cause a decrease in suction. When the preset cleaning cycle is completed, the PLC controller 6 automatically stops the suction fan 584. The entire cleaning process does not require manual intervention, realizing full automation from roller surface cleaning to debris collection, ensuring that the roller surface is always kept clean, thereby significantly improving the straightening quality of the board and production efficiency.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
