Description

Technical Field

[0001] The present application relates to the technical field of steel plate degreasing and cleaning, and in particular to a mechanical degreasing device for steel plate shearing equipment. Background Art

[0002] During the processing of steel plates, their surfaces are typically covered with a certain amount of oil, which is primarily used to prevent rust and reduce friction. However, during shearing operations, a large amount of oil residue remains on the steel plate surface and shearing equipment, which not only affects the quality of subsequent processing but can also cause equipment failure, so it is important to pay attention to it. Traditional degreasing methods mostly rely on manual cleaning, which is inefficient, time-consuming, labor-intensive, and highly polluting. At the same time, mechanical degreasing devices are used to automatically remove oil from steel plate shearing equipment before shearing, thereby improving the efficiency of steel plate degreasing.

[0003] Mechanical degreasing devices used in related technologies only use a single method, resulting in generally poor degreasing results. Furthermore, during the degreasing process, oil stains may adhere to certain areas of the equipment, resulting in suboptimal degreasing and even exacerbating equipment contamination. Therefore, improving the single method of degreasing devices and reducing the adhesion of oil stains has become a pressing technical challenge. There is an urgent need to develop more efficient, environmentally friendly, and intelligent degreasing solutions to improve overall production efficiency, enhance equipment lifespan, and ultimately achieve greater economic benefits.

In addition, by flushing the oil stains adhered to the oil removal parts, the situation where the oil removal effect is not ideal due to the attachment of oil stains to the oil removal parts is reduced, further improving the oil removal effect, and the oil stains scraped off and the oil stains under the rotating brush are gathered with the cleaning liquid, which is convenient for centralized treatment, thereby reducing the pollution of oil stains to the environment.

[0039] The following describes a mechanical oil removal device for steel plate shearing equipment according to an embodiment of the present application with reference to the accompanying drawings.

[0041] See also Figures 1 to 3The upper surface oil removal system 200 includes an upper base 210, a pressure plate roller 220, an upper oil scraping mechanism 230, an upper cleaning roller mechanism 240 and an upper flushing mechanism 250. The upper base 210 is slidably connected to the upper part of the conveying mechanism 100 with the dirty liquid box in the vertical direction. The pressure plate roller 220 is rotatably arranged at the front and rear ends of the upper base 210 respectively. The pressure plate roller 220 presses the upper surface of the steel plate. The upper oil scraping mechanism 230, the upper cleaning roller mechanism 240 and the upper flushing mechanism 250 are all arranged in the upper base 210. The upper cleaning roller mechanism 240 is located at the front end of the upper oil scraping mechanism 230. The upper oil scraping mechanism 230 scrapes the oil on the upper surface of the steel plate. The upper cleaning roller mechanism 240 rotates to clean the oil on the upper surface of the steel plate. The front of the upper flushing mechanism 250 The upper cleaning roller mechanism 240 and the upper oil scraping mechanism 230 are respectively flushed at the front and rear ends. The lower surface oil removal system 300 includes a lower base 310, a lower oil scraping mechanism 320, a lower cleaning roller mechanism 330 and a lower flushing mechanism 340. The lower base 310 is fixedly connected to the bottom of the conveying mechanism 100 with a dirty liquid box. The lower oil scraping mechanism 320, the lower cleaning roller mechanism 330 and the lower flushing mechanism 340 are all arranged in the lower base 310. The lower cleaning roller mechanism 330 is located at the front end of the lower flushing mechanism 340. The lower oil scraping mechanism 320 scrapes the oil on the lower surface of the steel plate. The lower cleaning roller mechanism 330 rotates to clean the oil on the lower surface of the steel plate. The front and rear ends of the lower flushing mechanism 340 flush the lower cleaning roller mechanism 330 and the lower oil scraping mechanism 320 respectively.When in use, the upper base 210 moves upward, and the pressure roller 220 moves up with the upper base 210 to reserve space for the steel plate, and the steel plate is sent into the conveying mechanism 100 with the dirty liquid box. The upper base 210 moves downward, and the upper flushing mechanism 250 and the lower flushing mechanism 340 are supplied with liquid. The pressure roller 220 presses the steel plate on the conveying mechanism 100 with the dirty liquid box, so that the conveying mechanism 100 with the dirty liquid box can convey the steel plate forward by friction. As the steel plate is conveyed forward, the steel plate is inserted between the upper scraper mechanism 230 and the lower scraper mechanism 320 and between the upper cleaning roller mechanism 240 and the lower cleaning roller mechanism 330. The upper scraper mechanism 230 and the lower scraper mechanism 320 are pressed on the upper surface and the lower surface of the steel plate respectively to scrape off some oil stains on both sides of the steel plate. The upper cleaning roller mechanism 240 and the lower cleaning roller mechanism 330 rotate to clean the steel plate. The upper and lower cleaning roller mechanisms 240 and 330 are used to clean the oil stains on the upper and lower surfaces of the steel plate. The upper and lower cleaning roller mechanisms 240 and 330 are used to clean the oil stains on the upper and lower surfaces of the steel plate. The cleaning liquid used to clean the oil stains flows through the steel plate into the bottom end of the conveying mechanism 100 with a dirty liquid box for centralized collection. The upper and lower cleaning roller mechanisms 240 and 330 are used to scrape off the cleaning liquid remaining on both sides of the steel plate. After the steel plate is degreased, the upper base 210 moves upward, and the rear ends of the upper and lower cleaning roller mechanisms 250 and 340 spray cleaning liquid. The cleaning liquid sprayed by the upper and lower cleaning roller mechanisms 250 and 340 cleans the oil stains adhered to the upper and lower scraping mechanisms 230 and 320. The mechanical oil removal device of the steel plate shearing equipment can quickly and thoroughly remove the oil stains on the steel plate through the oil scraping of the upper oil scraping mechanism 230 and the lower oil scraping mechanism 320, the oil brushing of the rotating upper cleaning roller mechanism 240 and the lower cleaning roller mechanism 330, and the washing and degreasing combination of the upper flushing mechanism 250 and the lower flushing mechanism 340, thereby greatly improving the oil removal efficiency and reducing the situation where the oil stains adhere to the shearing device when the steel plate enters the shearing device later. The oil stains adhered to the cleaning roller mechanism 240 and the lower cleaning roller mechanism 330 as well as the upper oil scraping mechanism 230 and the lower oil scraping mechanism 320 are reduced, thereby reducing the occurrence of unsatisfactory oil removal effects caused by the oil stains adhered to the upper cleaning roller mechanism 240 and the lower cleaning roller mechanism 330 as well as the upper oil scraping mechanism 230 and the lower oil scraping mechanism 320, thereby further improving the oil removal effect. Moreover, the scraped oil stains and the oil stains under the rotating brush are gathered at the bottom end of the conveying mechanism 100 with the dirty liquid box along with the cleaning liquid, which is convenient for centralized treatment and reduces the pollution of the oil stains to the environment.

[0042] See also Figures 1 to 4The upper base 210 includes an upper side plate 211, a first rotating rod 212, and a second rotating rod 213. The first rotating rod 212 is located in the middle between the two upper side plates 211. The upper oil scraper mechanism 230 is rotatably connected to the first rotating rod 212. The weight of the upper oil scraper mechanism 230 at the front end of the first rotating rod 212 is greater than the weight of the upper oil scraper mechanism 230 at the rear end of the first rotating rod 212. The second rotating rod 213 is rotatably connected to the lower portion between the front and rear ends of the two upper side plates 211. The pressure rollers 220 are rotatably connected to the second rotating rods 213. The front end of the upper oil scraper mechanism 230 rotates around the first rotating rod 212, allowing the upper oil scraper mechanism 230 to press against the upper surface of the steel plate. The pressure rollers 220 press the steel plate against the conveying mechanism 100 with a dirty liquid box. When the conveying mechanism 100 with a dirty liquid box conveys the steel plate, the pressure rollers 220 rotate around the second rotating rod 213, providing friction for conveying the steel plate. Limiting rods 214 are provided in both the upper base 210 and the lower base 310. The limiting rod 214 in the upper base 210 limits the downward swing angle of the front end of the upper oil scraping mechanism 230, and the limiting rod 214 in the lower base 310 limits the upward swing angle of the front end of the lower oil scraping mechanism 320.

The elastically extended end of the first elastic telescopic rod 234 abuts the lower side of the rear end of the upper counterweight swing plate 231. Transition grooves 232 are provided on both the upper counterweight swing plate 231 and the upper oil scraper plate 233 to reduce weight and provide space for the installation of the upper flushing mechanism 250. The first elastic telescopic rod 234 consists of a housing, a telescopic rod body, and a compression spring (not shown). The telescopic rod body is slidably inserted into the housing. The compression spring is located within the housing. The elastic force of the compression spring pushes the telescopic rod body toward the housing, causing the end of the telescopic rod body to abut the lower side of the rear end of the upper counterweight swing plate 231. The combined external forces of the compression spring force and the weight of the upper oil scraper 233 cause the scraping edge of the upper oil scraper 233 to press against the upper surface of the steel plate, scraping the oil from the steel plate.

[0044] See also Figures 1 to 6The upper cleaning roller mechanism 240 includes a liquid barrier structure 241 and a cleaning roller structure 242.

The cleaning roller structure 242 is rotatably connected to the interior of the upper base 210 at both ends. The cleaning roller structure 242 is located between the two liquid barrier structures 241. The cleaning roller structure 242 rotates to clean the upper surface of the steel plate, while the two liquid barrier structures 241 press against the upper surface of the steel plate. The lower cleaning roller mechanism 330 has the same structure as the upper cleaning roller mechanism 240 and is arranged symmetrically in the vertical direction. Liquid barrier spaces are formed between the liquid barrier structures 241 of the upper cleaning roller mechanism 240 and the upper surface of the steel plate, and between the liquid barrier structures 241 of the lower cleaning roller mechanism 330 and the lower surface of the steel plate, thereby reducing the possibility of cleaning liquid splashing across the liquid barrier spaces.

[0045] See also Figures 1 to 6The liquid isolation structure 241 includes a mounting block 2411, an elastic baffle 2412, a circular-section sealing strip 2413, and a clamping bolt 2414.

The clamping bolt 2414 is threadedly connected to the mounting block 2411 and compresses the elastic baffle 2412. If the circular-section sealing strip 2413 fails to press against the steel plate, the clamping bolt 2414 is loosened, the elastic baffle 2412 is pressed downward, and the circular-section sealing strip 2413 is re-pressed against the surface of the steel plate through the elastic baffle 2412. The clamping bolt 2414 is then re-tightened to lock the elastic baffle 2412. The lower part of the elastic partition 2412 is tilted forward, and the lower cleaning roller mechanism 330 and the upper cleaning roller mechanism 240 are symmetrically arranged in the vertical direction, so that the steel plates can be opened to each other through the elastic force of the elastic partition 2412, making it easy for the steel plates to be inserted between the circular cross-section sealing strips 2413 of the upper and lower symmetrically arranged elastic partitions 2412. The circular cross-section sealing strips 2413 form a seal between the steel plate surface and the elastic partition 2412, reducing the occurrence of cleaning liquid crossing the liquid isolation structure 241 and scattering on the steel plate surface, and the circular cross-section sealing strip 2413 on the liquid isolation structure 241 at the front end can scrape off the cleaning liquid remaining on the steel plate surface. The cleaning roller structure 242 includes a first rotating shaft 2421 and a cleaning roller 2422. The cleaning roller 2422 is fixedly mounted on the first rotating shaft 2421.

When the elastic double-stopper liquid control structure 255 is in place, the two-way liquid supply structure 254 and the liquid outlet pipe 256 at the front end supply liquid to the front liquid box 251 respectively. The liquid supply structure 254 and the liquid outlet pipe 256 at the rear end close the liquid supply to the rear liquid box 252. A control rod 150 is provided in the conveying mechanism 100 with the dirty liquid box. After the elastic double-stopper liquid control structure 255 rises and presses against the control rod 150, the elastic double-stopper liquid control structure 255 slides away from its original position in the two-way liquid supply structure 254.

The cleaning liquid is supplied to the front liquid box 251 and the rear liquid box 252 through the two-way liquid supply structure 254 and the liquid outlet pipe 256. The upper base 210 moves downward. At this time, the elastic double-piston liquid control structure 255 is in place. The two-way liquid supply structure 254 and the front liquid outlet pipe 256 supply liquid to the front liquid box 251 respectively, and the two-way liquid supply structure 254 and the rear liquid outlet pipe 256 close the liquid supply to the rear liquid box 252. The two-way liquid supply structure 254 concentrates on supplying liquid to the front liquid box 251 of the upper flushing mechanism 250 and the lower flushing mechanism 340, reducing the situation where the cleaning liquid flows around with the steel plate due to the discharge of liquid from the rear liquid box 252 when the steel plate is transported. The upper cleaning roller mechanism 240 and the lower cleaning roller mechanism 330 are soaked and flushed through the nozzle 253 on the front liquid box 251, which facilitates the cleaning of the upper and lower surfaces of the steel plate and the cleaning of the upper cleaning roller mechanism 240 and the lower cleaning roller mechanism 330.After the steel plate is degreased, the upper base 210 moves upward, and the upper base 210 drives the elastic double-stopper liquid control structure 255 to move upward accordingly.

Since the steel plate is not between the upper scraping mechanism 230 and the lower scraping mechanism 320, the flushed oil falls into the conveying mechanism 100 with the dirty liquid box under the action of gravity, which is convenient for the centralized collection of oil and reduces the pollution of oil to the environment.

[0058] Specifically, the working principle of the mechanical oil removal device of the steel plate shearing equipment is as follows: when in use, the second motor 520 drives the double-threaded screw 540 through the principle of helical gear meshing, and the double-threaded screw 540 drives the two movable seats 550 at both ends of the double-threaded screw 540 to approach each other through the principle of thread transmission, and the upper base 210 moves upward, and the pressure plate roller 220 moves up with the upper base 210 to reserve space for the steel plate, and the steel plate is fed between the pressure plate roller 220 and the active roller 130, and the second motor 520 drives the two movable seats 550 to move away from each other, and the upper base 210 moves downward. At this time, the tension spring 2553 pulls the top plate 2551, and the top plate 2551 pushes the sealing plug 2554 upward through the two piston rods 2552 to press the front liquid box sealing compartment 2 543 and the top of the rear liquid box sealing cabin 2544, the pressure in the upper and lower ends of the front liquid box sealing cabin 2543 and the rear liquid box sealing cabin 2544 is released through the pressure reducing pipe 2545, which facilitates the movement of the sealing plug 2554 to the highest end. At this time, the sealing plug 2554 returns to its original position, the rear end of the double liquid outlet pipe 2541 and the rear end liquid outlet pipe 256 close the liquid supply to the rear liquid box 252, and the front end of the double liquid outlet pipe 2541 and the front end liquid outlet pipe 256 open the liquid supply to the front liquid box 251. The front end of the double liquid outlet pipe 2541 and the front end liquid outlet pipe 256 concentrate on supplying liquid to the front liquid box 251, reducing the situation where the cleaning liquid flows around with the steel plate due to the discharge of liquid from the rear liquid box 252 when the steel plate is transported, and the cleaning liquid flows around with the steel plate through the nozzle 253 on the front liquid box 251. The upper cleaning roller mechanism 240 and the cleaning roller 2422 of the lower cleaning roller mechanism 330 are soaked and rinsed, and the first motor 412 is started. The first motor 412 drives the active double pulley 413, and the active double pulley 413 drives the rear pulley 430 and the follower double pulley 420 through the belt 450. The rear pulley 430 drives the active roller 130 at the rear end, and the follower double pulley 420 drives the front pulley 442 through the belt 450. The front pulley 442 drives the active roller 130 at the front end. The active rollers 130 at the front and rear ends cooperate with the pressure plate roller 220 to apply pressure to the steel plate to realize forward transportation of the steel plate. The steel plate extends between the scraping edges of the upper scraper plate 233 and the lower scraper plate 322, and is moved by the elastic force of the first elastic telescopic rod 234 and the weight of the upper scraper plate 233. Under the dual external force of force, the scraping edge of the upper scraper plate 233 is pressed against the upper surface of the steel plate to scrape the oil from the upper surface of the steel plate. Under the dual action of the elastic force of the second elastic telescopic rod 323 and the gravity of the lower counterweight swing plate 321, the scraping edge of the lower scraper plate 322 is pressed against the lower surface of the steel plate to scrape the oil from the lower surface of the steel plate. The steel plate is transported between the upper cleaning roller mechanism 240 and the cleaning roller 2422 of the lower cleaning roller mechanism 330. The front pulley 442 drives the large gear 441 through the active roller 130. The large gear 441 drives the small gear 466 through the gear meshing principle. The small gear 466 drives the first rotating shaft 2421 of the lower cleaning roller mechanism 330. The first rotating shaft 2421 of the lower cleaning roller mechanism 330 drives the second bevel gear 465 to rotate.The second beveled teeth 465 drive the first beveled teeth 464 in the fixed box 462 through the principle of beveled gear meshing, and the first beveled teeth 464 in the fixed box 462 drive the prismatic rotating shaft 461 to rotate, and the prismatic rotating shaft 461 drives the first beveled teeth 464 in the movable box 463, and the first beveled teeth 464 in the movable box 463 drive the second beveled teeth 465 on the upper cleaning roller mechanism 240 through the principle of beveled gear meshing, and the second beveled teeth 465 on the upper cleaning roller mechanism 240 drive the first rotating shaft 2421 of the lower cleaning roller mechanism 330 to rotate, and the first rotating shaft 2421 drives the cleaning roller 2422 to rotate to scrub the steel plate. Liquid isolation spaces are formed between the liquid isolation structure 241 of the upper cleaning roller mechanism 240 and the upper surface of the steel plate, and between the liquid isolation structure 241 of the lower cleaning roller mechanism 330 and the lower surface of the steel plate, thereby reducing the occurrence of splashing of cleaning liquid across the liquid isolation space. The liquid isolation structure 241 at the front end can scrape off the cleaning liquid remaining on the surface of the steel plate. After the steel plate is degreased, the second motor 520 drives the double-threaded screw 540 through the principle of helical gear meshing. The double-threaded screw 540 drives the two movable seats 550 at both ends of the double-threaded screw 540 to approach each other through the principle of thread transmission. The upper base 210 moves upward, and the upper base 210 drives the elastic double-piston liquid control structure 255 to move upward accordingly. When the control rod 150 presses against the top plate 2551, the top plate 2551 pulls the sealing plug 2554 downward through the two piston rods 2552 to press the bottom ends of the front liquid box sealing cabin 2543 and the rear liquid box sealing cabin 2544. The front liquid box sealing cabin 2543 and the rear liquid box sealing cabin 2544 are The pressure within the upper and lower ends of the closed chamber 2544 is released through the pressure-reducing pipe 2545, allowing the closed chamber plug 2554 to move to its bottom end. The tension spring 2553 extends, increasing its elastic force. At this point, the rear end of the dual liquid outlet pipe 2541 and the rear liquid outlet pipe 256 open to supply liquid to the rear liquid box 252, while the front end of the dual liquid outlet pipe 2541 and the front liquid outlet pipe 256 close to supply liquid to the front liquid box 251. As the upper base 210 rises and falls, the liquid supply direction of the dual liquid outlet pipe 2541 automatically changes, eliminating the need for manual control to change the liquid supply direction of the dual liquid outlet pipe 2541, facilitating automated management.

[0059] The mechanical oil removal device of the steel plate shearing equipment can quickly and thoroughly remove the oil stains on the steel plate through the upper scraper 233 and the lower scraper 322 scraping oil, the rotating cleaning roller 2422 brushing oil, and the upper flushing mechanism 250 and the lower flushing mechanism 340 washing and degreasing combination, which greatly improves the oil removal efficiency and reduces the situation where the oil stains adhere to the shearing equipment when the steel plate enters the shearing equipment later. The upper flushing mechanism 250 and the lower flushing mechanism 340 flush the oil stains adhering to the cleaning roller 2422 and the upper scraper 233 and the lower scraper 322, reducing the situation where the oil removal effect is not ideal due to the attachment of oil stains to the cleaning roller 2422 and the upper scraper 233 and the lower scraper 322, further improving the oil removal effect. The scraped oil stains and the oil stains under the rotating brush are gathered at the bottom of the collecting tank with the cleaning liquid, which is convenient for centralized treatment and reduces the pollution of oil stains to the environment.
