Description

Technical Field

[0001] This application relates to the technical field of steel plate degreasing and cleaning, and more particularly, to a mechanical degreasing device for a steel plate shearing equipment. Background Art

[0002] During the processing of steel plates, a certain amount of oil stains usually cover their surfaces. These oil stains are mainly used to prevent rust and reduce friction. However, during the shearing operation, a large amount of oil stains will remain on the surface of the steel plate and the shearing equipment, which not only affects the subsequent processing quality but may also cause equipment failures. Therefore, this must be taken seriously. Traditional degreasing methods are mostly manual cleaning, which is inefficient, time-consuming, laborious, and highly polluting. At the same time, mechanical degreasing devices are used for automatic degreasing before the steel plate shearing equipment shears, so as to improve the efficiency of steel plate degreasing.

[0003] In the related art, the degreasing method of the mechanical degreasing device is single, and the degreasing effect is generally poor. Moreover, during the degreasing process, some degreasing parts will also adhere to oil stains, resulting in an unsatisfactory degreasing effect and even exacerbating equipment pollution. Therefore, how to improve the single degreasing method of the existing mechanical degreasing device and reduce the adhesion of oil stains has become an urgent technical problem to be solved. There is an urgent need to develop a more efficient, environmentally friendly, and intelligent degreasing solution to improve the overall production efficiency and the service life of the equipment, and ultimately achieve higher economic benefits. Summary of the Invention

For this purpose, this application provides a mechanical degreasing device for a steel plate shearing equipment. The mechanical degreasing device for the steel plate shearing equipment can quickly and thoroughly remove the oil stains on the steel plate through a combination of scraping oil, rotating brush oil, and rinsing degreasing, greatly improving the degreasing efficiency. It also reduces the situation where oil stains adhere to the shearing equipment when the steel plate enters the shearing equipment subsequently. And by rinsing and flushing the oil stains adhered to the degreasing parts, it reduces the occurrence of an unsatisfactory degreasing effect caused by the adhesion of oil stains to the degreasing parts, further improving the degreasing effect. Moreover, the scraped oil stains and the oil stains brushed off by the rotating brush converge with the cleaning liquid, which is convenient for centralized treatment and reduces the environmental pollution caused by oil stains.

Limit rods 214 are arranged both in the upper base 210 and in the lower base 310. The limit 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 limit rod 214 in the lower base 310 limits the upward swing angle of the front end of the lower oil scraping mechanism 320.

[0027] Please refer to Figures 1 to 5 , the upper oil scraping mechanism 230 includes an upper counterweight swing plate 231, an upper oil scraping plate 233 and a first elastic telescopic rod 234. The middle part of the upper counterweight swing plate 231 is rotatably sleeved in the upper base 210. The upper oil scraping plate 233 is fixedly inclined forward at the front end of the upper counterweight swing plate 231. A scraping edge is arranged at the lower end of the upper oil scraping plate 233. The first elastic telescopic rod 234 is arranged on the inner walls on both sides of the upper base 210. The elastic extending end of the first elastic telescopic rod 234 abuts against the lower side of the rear end of the upper counterweight swing plate 231. Transition grooves 232 are formed in both the upper counterweight swing plate 231 and the upper oil scraping plate 233 for weight reduction and to provide space for the installation of the upper flushing mechanism 250. The first elastic telescopic rod 234 is composed of a housing, a telescopic rod body and a compression spring (not shown in the figure). The telescopic rod body is slidably inserted into the housing. The compression spring is arranged in the housing. The elastic force of the compression spring pushes the telescopic rod body to move towards the housing. The end of the telescopic rod body abuts against the lower side of the rear end of the upper counterweight swing plate 231. Under the dual external forces of the elastic force of the compression spring and the gravity of the upper oil scraping plate 233, the scraping edge of the upper oil scraping plate 233 presses on the upper surface of the steel plate to perform the oil scraping operation on the upper surface of the steel plate.

[0028] Please refer to Figures 1 to 6, the upper cleaning roller mechanism 240 includes a liquid separation structure 241 and a cleaning roller structure 242. There are two liquid separation structures 241, which are arranged in parallel inside the upper base 210. Both ends of the cleaning roller structure 242 are rotatably connected inside the upper base 210. The cleaning roller structure 242 is located between the two liquid separation structures 241. The cleaning roller structure 242 rotates to clean the upper surface of the steel plate, and the two liquid separation 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 the lower cleaning roller mechanism 330 and the upper cleaning roller mechanism 240 are symmetrically arranged in the vertical direction. A liquid separation space is formed between the liquid separation structure 241 of the upper cleaning roller mechanism 240 and the upper surface of the steel plate, and between the liquid separation structure 241 of the lower cleaning roller mechanism 330 and the lower surface of the steel plate, reducing the occurrence of the cleaning liquid splashing everywhere across the liquid separation space.

[0029] Please refer to Figures 1 to 6, the liquid separation structure 241 includes a mounting block 2411, an elastic partition 2412, a circular cross-section sealing strip 2413, and a compression bolt 2414. The mounting block 2411 is fixedly connected to the inside of the upper base 210. The upper part of the elastic partition 2412 is slidably inserted into the mounting block 2411. The lower part of the elastic partition 2412 slopes forward. The circular cross-section sealing strip 2413 is fixedly connected to the bottom of the elastic partition 2412. The circular cross-section sealing strip 2413 is pressed against the surface of the steel plate. The compression bolt 2414 is threadedly connected to the mounting block 2411, and the compression bolt 2414 presses the elastic partition 2412. When the circular cross-section sealing strip 2413 cannot tightly press the steel plate, loosen the compression bolt 2414, press down the elastic partition 2412, and through the elastic partition 2412, press the circular cross-section sealing strip 2413 tightly on the surface of the steel plate again. Then tighten the compression bolt 2414 again to lock the elastic partition 2412. The lower part of the elastic partition 2412 slopes forward, and the lower cleaning roller mechanism 330 and the upper cleaning roller mechanism 240 are symmetrically arranged in the vertical direction, enabling the steel plate to be opened by the elastic force of the elastic partition 2412, facilitating the insertion of the steel plate between the circular cross-section sealing strips 2413 of the elastic partition 2412 arranged symmetrically up and down. The circular cross-section sealing strip 2413 forms a seal between the surface of the steel plate and the elastic partition 2412, reducing the occurrence of the cleaning liquid passing over the liquid separation structure 241 and scattering on the surface of the steel plate. Moreover, the circular cross-section sealing strip 2413 on the liquid separation structure 241 at the front end can scrape off the residual cleaning liquid on the surface of the steel plate. The cleaning roller structure 242 includes a first rotating shaft 2421 and a cleaning roller 2422. The cleaning roller 2422 is fixedly sleeved on the first rotating shaft 2421. The two ends of the first rotating shaft 2421 of the upper cleaning roller mechanism 240 rotate through both sides inside the upper base 210. The two ends of the first rotating shaft 2421 of the lower cleaning roller mechanism 330 rotate through both sides inside the lower base 310. The ends of both sides of the first rotating shaft 2421 extend outside both sides of the conveying mechanism 100 with a waste liquid box. The ends of both sides of the first rotating shaft 2421 on the upper base 210 can slide in the vertical direction on both sides of the conveying mechanism 100 with a waste liquid box. The first rotating shaft 2421 drives the cleaning roller 2422 to rotate, and the surface of the steel plate is scrubbed by the rotation of the cleaning roller 2422. The outer ring of the cleaning roller 2422 is a flexible brush body, which can adapt to the thickness change of the steel plate.

[0030] Please refer to Figures 1 to 8, the upper flushing mechanism 250 includes a front liquid box 251, a rear liquid box 252, a spray head 253, a two-way liquid supply structure 254, an elastic double plug column liquid control structure 255, and a liquid outlet pipe 256. The lower flushing mechanism 340 includes a front liquid box 251, a rear liquid box 252, and a spray head 253. The front liquid box 251 and the rear liquid box 252 are arranged in the upper base 210. The spray heads 253 are arranged on the front liquid box 251 and the rear liquid box 252 at equal intervals. The spray heads 253 communicate with the interiors of the front liquid box 251 and the rear liquid box 252. The spray heads 253 of the front liquid box 251 on the upper flushing mechanism 250 face the upper cleaning roller mechanism 240, and the spray heads 253 of the rear liquid box 252 on the upper flushing mechanism 250 face the oil scraping part of the upper oil scraping mechanism 230. The spray heads 253 of the front liquid box 251 on the lower flushing mechanism 340 face the lower cleaning roller mechanism 330, and the spray heads 253 of the rear liquid box 252 on the lower flushing mechanism 340 face the oil scraping part of the lower oil scraping mechanism 320. Both the front end and the rear end of the two-way liquid supply structure 254 are connected to a liquid outlet pipe 256. The liquid outlet at the front end of the two-way liquid supply structure 254 and the liquid outlet pipe 256 are respectively connected to the front liquid box 251 of the upper flushing mechanism 250 and the lower flushing mechanism 340. The liquid outlet at the rear end of the two-way liquid supply structure 254 and the liquid outlet pipe 256 are respectively connected to the rear liquid box 252 of the upper flushing mechanism 250 and the lower flushing mechanism 340. The elastic double plug column liquid control structure 255 is arranged on the two-way liquid supply structure 254. When the elastic double plug column liquid control structure 255 is in its original position, 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 liquid supply of the two-way liquid supply structure 254 and the rear liquid outlet pipe 256 to the rear liquid box 252 is closed. A control rod 150 is arranged in the conveying mechanism 100 with a waste liquid box. After the elastic double plug column liquid control structure 255 rises and abuts against the control rod 150, the elastic double plug column liquid control structure 255 slides in the two-way liquid supply structure 254 and leaves its original position. The two-way liquid supply structure 254 and the rear liquid outlet pipe 256 supply liquid to the rear liquid box 252 respectively, and the liquid supply of the two-way liquid supply structure 254 and the front liquid outlet pipe 256 to the front liquid box 251 is closed. 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 plug column liquid control structure 255 is in its original position. 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 liquid supply of the two-way liquid supply structure 254 and the rear liquid outlet pipe 256 to the rear liquid box 252 is closed. The two-way liquid supply structure 254 centrally supplies liquid to the front liquid box 251 of the upper flushing mechanism 250 and the lower flushing mechanism 340, reducing the occurrence of the situation where the cleaning liquid flows everywhere with the steel plate due to the liquid outlet of the rear liquid box 252 during the conveying of the steel plate. The upper cleaning roller mechanism 240 and the lower cleaning roller mechanism 330 are wetted and flushed through the spray heads 253 on the front liquid box 251, facilitating the washing 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 degreasing of the steel plate is completed, the upper base 210 moves upward. The upper base 210 drives the elastic double-plunger liquid control structure 255 to move upward accordingly. After the elastic double-plunger liquid control structure 255 abuts against the control rod 150, the elastic double-plunger liquid control structure 255 remains stationary. The two-way liquid supply structure 254 continues to move upward. The elastic double-plunger liquid control structure 255 slides out of its original position within the two-way liquid supply structure 254. The liquid supply from the two-way liquid supply structure 254 and the front liquid outlet pipe 256 to the front liquid box 251 is closed, and the liquid supply from the two-way liquid supply structure 254 and the rear liquid outlet pipe 256 to the rear liquid box 252 is opened. The two-way liquid supply structure 254 supplies liquid to the rear liquid box 252 of the centralized upward flushing mechanism 250 and the lower flushing mechanism 340. The scraping parts of the upper scraping oil mechanism 230 and the lower scraping oil mechanism 320 are flushed through the spray heads 253 on the rear liquid box 252. Since the steel plate is not between the upper scraping oil mechanism 230 and the lower scraping oil mechanism 320, the flushed oil and dirt fall into the conveying mechanism 100 with a dirty liquid box under the action of gravity, which is convenient for centralized collection of oil and dirt and reduces environmental pollution caused by oil and dirt.

[0031] Please refer to Figures 1 to 8 , the lower base 310 includes a lower side plate 311, a third rotating rod 312, and a connecting block 313. The third rotating rod 312 is arranged in the middle between the two lower side plates 311. The lower scraping oil mechanism 320 is rotatably sleeved on the third rotating rod 312. The weight of the lower scraping oil mechanism 320 at the rear end of the third rotating rod 312 is greater than the weight of the lower scraping oil mechanism 320 at the front end of the third rotating rod 312. The front end of the lower scraping oil mechanism 320 flips around the third rotating rod 312, enabling the lower scraping oil mechanism 320 to press on the lower surface of the steel plate.

The top ends of the two piston rods 2552 are provided with sealing plugs 2554. The two sealing plugs 2554 are respectively slidably connected to the front liquid box sealing cabin 2543 and the rear liquid box sealing cabin 2544. The upper end of the long piston rod 2552 slides through the bottom end of the front liquid box sealing cabin 2543 into the front liquid box sealing cabin 2543, and the upper end of the short piston rod 2552 slides through the bottom end of the rear liquid box sealing cabin 2544 into the rear liquid box sealing cabin 2544. The tension spring 2553 is provided on the upper side of the top plate 2551 and the double liquid outlet pipe 2541, the tension spring 2553 pulls the top plate 2551, and the top plate 2551 pushes the sealing plug 2554 through the two piston rods 2552 to press the top of the front liquid box sealing cabin 2543 and the rear liquid box sealing cabin 2544 upward. At this time, the sealing plug 2554 is in place, the rear section of the double liquid outlet tube 2541 is closed, and the front section of the double liquid outlet tube 2541 is opened. The control rod 150 can resist the top plate 2551, and the top plate 2551 pulls the sealing plug 2554 through the two piston rods 2552 to press the bottom of the front liquid box sealing cabin 2543 and the rear liquid box sealing cabin 2544 downward. At this time, the rear section of the double liquid outlet tube 2541 is opened, and the front section of the double liquid outlet tube 2541 is closed.When the elastic double-plug column liquid control structure 255 is in place, the tension spring 2553 pulls the top plate 2551. The top plate 2551 pushes the sealing cabin plug column 2554 upward through two piston rods 2552 to press against the top ends inside the front liquid box sealing cabin 2543 and the rear liquid box sealing cabin 2544. The pressure inside 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 relief connecting pipe 2545, facilitating the movement of the sealing cabin plug column 2554 to the highest end. At this time, the sealing cabin plug column 2554 is in place, and the liquid supply from the rear end of the double-outlet pipe 2541 and the rear liquid outlet pipe 256 to the rear liquid box 252 is closed, while the liquid supply from the front end of the double-outlet pipe 2541 and the front liquid outlet pipe 256 to the front liquid box 251 is opened.

The pressure inside 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 relief connecting pipe 2545, facilitating the movement of the sealing cabin plug column 2554 to the lowest end. The tension spring 2553 elongates, and the elastic force of the tension spring 2553 increases. At this time, the liquid supply from the rear end of the double-outlet pipe 2541 and the rear liquid outlet pipe 256 to the rear liquid box 252 is opened, while the liquid supply from the front end of the double-outlet pipe 2541 and the front liquid outlet pipe 256 to the front liquid box 251 is closed.

The lower oil scraping plate 322 is fixedly inclined forward on the upper side of the front end of the lower counterweight swing plate 321. A scraping blade edge is provided at the upper end of the lower oil scraping plate 322. The second elastic telescopic rod 323 is arranged on the inner walls on both sides of the lower base 310, and the elastic extension end of the second elastic telescopic rod 323 abuts against the upper side of the rear end of the lower counterweight swing plate 321.

The first frame 510 is fixedly connected to the outer wall of the conveying mechanism 100 with the dirty liquid box, the second motor 520 is installed on the first frame 510, both ends and the middle of the double-threaded screw 540 are rotatably connected to the outer wall of the conveying mechanism 100 with the dirty liquid box through the bearing seat 530, and the output end of the second motor 520 is connected to the outer wall of the conveying mechanism 100 with the dirty liquid box through the inclined The teeth are engaged with the double-threaded screw 540, and the threads at both ends of the double-threaded screw 540 are in opposite directions. The movable seat 550 is respectively connected to the two ends of the double-threaded screw 540 through threads. Double-layer rocker arms 560 are hinged on the upper sides of the two movable seats 550. Two first fixed shafts 260 are arranged on the outer wall of the upper base 210. The ends of the double-layer rocker arms 560 on the upper sides of the two movable seats 550 are respectively hinged to the two first fixed shafts 260, and the double-layer rocker arms 560 on the upper sides of the two movable seats 550 are distributed in an "eight" shape.

When the two movable seats 550 move away from each other, the double-layer rocker arm 560 drives the upper base 210 to move downward through the first fixed shaft 260. When the two movable seats 550 approach each other, the double-layer rocker arm 560 drives the upper base 210 to move upward through the first fixed shaft 260.

[0042] Specifically, the working principle of the mechanical oil removal device of the steel plate shearing equipment: During use, the second motor 520 drives the double-threaded screw rod 540 through the helical gear meshing principle. The double-threaded screw rod 540 drives the two movable seats 550 at both ends of the double-threaded screw rod 540 to approach each other through the screw thread transmission principle. The upper base 210 moves upward, and the pressing plate roller 220 moves upward with the upper base 210 to reserve space for the placement of the steel plate. The steel plate is fed between the pressing plate roller 220 and the driving roller 130. 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 column 2554 upward through the two piston rods 2552 to press against the top ends inside the front liquid box closed cabin 2543 and the rear liquid box closed cabin 2544. The pressure inside the upper and lower ends of the front liquid box closed cabin 2543 and the rear liquid box closed cabin 2544 is released through the pressure reducing communication pipe 2545, facilitating the sealing plug column 2554 to move to the highest end. At this time, the sealing plug column 2554 returns to its original position, and the liquid supply from the rear end of the double-outlet pipe 2541 and the rear outlet pipe 256 to the rear liquid box 252 is closed, and the liquid supply from the front end of the double-outlet pipe 2541 and the front outlet pipe 256 to the front liquid box 251 is opened. The front end of the double-outlet pipe 2541 and the front outlet pipe 256 supply liquid to the front liquid box 251 concentratedly, reducing the situation that the cleaning liquid flows everywhere with the steel plate when the steel plate is transported due to the liquid discharge from the rear liquid box 252. The cleaning roller 2422 of the upper cleaning roller mechanism 240 and the lower cleaning roller mechanism 330 is wetted and rinsed through the spray head 253 on the front liquid box 251. The first motor 412 is started. The first motor 412 drives the driving double pulley 413. The driving double pulley 413 drives the rear pulley 430 and the follower double pulley 420 through the belt 450. The rear pulley 430 drives the driving roller 130 at the rear end. The follower double pulley 420 drives the front pulley 442 through the belt 450. The front pulley 442 drives the driving roller 130 at the front end. Through the cooperation of the driving rollers 130 at the front and rear ends and the pressing plate roller 220 to press on the steel plate, the forward transportation of the steel plate is realized. The steel plate extends between the oil scraping cutting edges of the upper oil scraping plate 233 and the lower oil scraping plate 322. Under the dual external forces of the elastic force of the first elastic telescopic rod 234 and the gravity of the upper oil scraping plate 233, the oil scraping cutting edge of the upper oil scraping plate 233 presses on the upper surface of the steel plate for the oil scraping operation on the upper surface of the steel plate. Under the dual actions of the elastic force of the second elastic telescopic rod 323 and the gravity of the lower counterweight swing plate 321, the oil scraping cutting edge of the lower oil scraping plate 322 presses on the lower surface of the steel plate for the oil scraping operation on the lower surface of the steel plate. The steel plate is transported between the cleaning rollers 2422 of the upper cleaning roller mechanism 240 and the lower cleaning roller mechanism 330. The front pulley 442 drives the large gear 441 through the driving 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 helical gear 465 to rotate.The second helical gear 465 drives the first helical gear 464 in the fixed box 462 through the principle of helical gear meshing. The first helical gear 464 in the fixed box 462 drives the rhombic rotating shaft 461 to rotate. The rhombic rotating shaft 461 drives the first helical gear 464 in the movable box 463. The first helical gear 464 in the movable box 463 drives the second helical gear 465 on the upper cleaning roller mechanism 240 through the principle of helical gear meshing. The second helical gear 465 on the upper cleaning roller mechanism 240 drives the first rotating shaft 2421 of the lower cleaning roller mechanism 330 to rotate. The first rotating shaft 2421 drives the cleaning roller 2422 to rotate for scrubbing the steel plate. A liquid separation space is formed between the liquid separation structure 241 of the upper cleaning roller mechanism 240 and the upper surface of the steel plate, and between the liquid separation structure 241 of the lower cleaning roller mechanism 330 and the lower surface of the steel plate, reducing the occurrence of the cleaning liquid splashing everywhere across the liquid separation space. The liquid separation structure 241 at the front end can scrape off the residual cleaning liquid on the surface of the steel plate. After the degreasing of the steel plate is completed, the second motor 520 drives the double-threaded screw rod 540 through the principle of helical gear meshing. The double-threaded screw rod 540 drives the two movable seats 550 at both ends of the double-threaded screw rod 540 to approach each other through the principle of screw drive. The upper base 210 moves upward. The upper base 210 drives the elastic double-plug liquid control structure 255 to move upward accordingly. When the control rod 150 abuts against the top plate 2551, the top plate 2551 pulls the sealing cabin plug 2554 downward through the two piston rods 2552 to press against the bottom ends inside the front liquid box closed cabin 2543 and the rear liquid box closed cabin 2544. The pressure inside the upper and lower ends of the front liquid box closed cabin 2543 and the rear liquid box closed cabin 2544 is released through the pressure relief through pipe 2545, facilitating the movement of the sealing cabin plug 2554 to the bottommost end. The tension spring 2553 elongates, and the elastic force of the tension spring 2553 increases. At this time, the liquid supply from the rear end of the double-outlet pipe 2541 and the rear outlet pipe 256 to the rear liquid box 252 is opened, and the liquid supply from the front end of the double-outlet pipe 2541 and the front outlet pipe 256 to the front liquid box 251 is closed. As the upper base 210 rises and falls, the liquid supply direction of the double-outlet pipe 2541 automatically changes, eliminating the need for manual control of the liquid supply direction change of the double-outlet pipe 2541, facilitating automated management.

[0043] 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 combination of oil scraping by the upper oil scraping plate 233 and the lower oil scraping plate 322, oil brushing by the rotating cleaning roller 2422, and oil removal by washing with the upper washing mechanism 250 and the lower washing mechanism 340, greatly improving the oil removal efficiency. It also reduces the situation where oil stains adhere to the shearing equipment when the steel plate enters the shearing equipment subsequently. Moreover, the upper washing mechanism 250 and the lower washing mechanism 340 flush and clean the oil stains adhered to the cleaning roller 2422, the upper oil scraping plate 233, and the lower oil scraping plate 322, reducing the occurrence of the situation where the oil removal effect is not ideal due to the adhesion of oil stains to the cleaning roller 2422, the upper oil scraping plate 233, and the lower oil scraping plate 322, further improving the oil removal effect. In addition, the scraped oil stains and the oil stains brushed by the rotating brush converge at the bottom of the sewage collection tank along with the cleaning liquid, facilitating centralized treatment and reducing environmental pollution caused by oil stains.
