Description

Technical Field

[0001] The invention belongs to the technical field of accessories for slitting machines, and particularly relates to a dust removal device for the surface of cold-rolled steel sheets in a slitting machine production line. Background Art

[0002] Cold-rolled steel sheets are also known as cold-rolled steel strips. A steel strip refers to a conveyor belt made of carbon steel as the traction and carrying component of a belt conveyor, and can also be used for bundling goods; it is a narrow and long steel plate produced by various rolling mills to meet the needs of different industrial sectors for industrial production of various metal or mechanical products. A steel strip, also known as a strip steel, has a width within 1300 mm, and its length varies slightly according to the size of each roll. Strip steel is generally supplied in coils, and has the advantages of high dimensional accuracy, good surface quality, easy processing, and material saving. Strip steel is divided into two categories: ordinary strip steel and high-quality strip steel according to the materials used.

[0003] The prior art CN222077352U discloses a dust removal device for the surface of a steel strip in a slitting machine production line, including a box body. An inlet bin is provided at the middle position of the box body. Two dust suction components are symmetrically arranged up and down inside the inlet bin. The dust suction component includes a first strip-shaped suction pipe and a second strip-shaped suction pipe. One end of the first strip-shaped suction pipe is inserted into the box body through the bin wall of the inlet bin and is connected to a dust collector installed on the side wall of the box body through a connecting component. The other end of the first strip-shaped suction pipe is connected to the second strip-shaped suction pipe. The second strip-shaped suction pipe is sleeved on the first strip-shaped suction pipe in an adjustable position. A dust scraping component is installed on the rear pipe wall of the end faces where the two second strip-shaped suction pipes are close to each other. When this device removes dust from the surface of a sheet, the dust on the surface of the steel plate is scraped off by the dust scraping component. Since the brush on the scraping component cannot rotate, after a long time of scraping, a lot of dust will adhere to the brush, and thus it cannot ensure the full dust removal of the steel plate.

The air suction end of the high-pressure blower 7 is connected to one side of the dust stripping module 5 through a channel A8. The sheet is smoothly moved in the machine cover 1 through the sheet guiding module 2. During the movement of the sheet, the dust removal module 4 removes dust from both sides of the sheet through a high-speed rotating dust cleaning brush 45 to ensure full cleaning of the sheet. With the cooperation of the high-pressure blower 7, the removed dust is sucked into the dust stripping module 5 through the dust suction module 3, and the dust stripping module 5 strips the inhaled dust to ensure dust collection.

[0021] Refer to Figure 5 , the sheet guiding module 2 includes a pair of brackets A21 fixedly connected to the upper end inside the machine cover 1. A guiding roller 22 is rotatably connected between the pair of brackets A21, and the sheet is carried on the guiding roller 22, thereby ensuring the smooth movement of the sheet in the machine cover 1 for dust removal work in the machine cover 1.

[0022] Refer to Figure 1 , Figure 2 And Figure 5 , the dust suction module 3 includes a pair of O-shaped channels 31 fixedly connected to the inside of the machine cover 1. The pair of O-shaped channels 31 are opposite to the sheet inlet and outlet on the machine cover 1. The pair of O-shaped channels 31 are connected through a channel F32. A channel B33 is connected to the channel F32. The lower end of the channel B33 is connected to a channel C34. The lower end of the channel C34 is connected to a channel D35. A number of channels E36 are connected to the side of the channel D35. A number of dust suction ports are reserved on the inner side wall of the O-shaped channel 31 and the upper end of the channel E36. The sheet can pass through the O-shaped channel 31, and the cleaned dust is sucked into the channel B33 through the dust suction ports on the O-shaped channel 31 and the channel E36, and then enters the dust stripping module 5 for dust stripping.

[0023] Refer to Figures 1-5The dust removal module 4 includes a pair of brackets B41 fixedly connected to the upper end of the inner side of the hood 1, and slideways 42 are reserved on both sides of the brackets B41 vertically. A slider 43 is movably installed in the slideway 42. One side of the slider 43 is connected to the other side of the slideway 42 via an elastic member 44. A cleaning brush 45 is screwed between the two opposite sliders 43. A servo motor 46 is fixedly connected to the outer side of one of the sliders 43. The rotating part of the servo motor 46 is connected to one side of the corresponding cleaning brush 45. A hydraulic rod 47 is fixedly connected to the outer wall of the two brackets B41 on the same side of the two groups of dust removal modules 4. The movable end of the hydraulic rod 47 is fixedly connected to the fixed block 48. The side wall of the fixed block 48 is screwed to a movable column 49. The cleaning brush 45 is fixedly connected to the movable column 49 on both sides. Sprockets 410 are fixedly connected to the movable column 49 on both sides. The three sprockets 410 on the same side are connected through a chain 411. When cleaning the surface of the steel plate, The plate passes through a pair of cleaning brushes 45, and the hydraulic rod 47 extends to push the movable column 49 to move outward. Under the cooperation of the chain 411, the slider 43 connected to the sprocket 410 is driven to approach each other, and the elastic member 44 extends, so that the pair of cleaning brushes 45 are moved close to each other, and then the cleaning brushes 45 are brought into contact with the surface of the plate, so as to adjust the cleaning brushes 45 and ensure that the cleaning brushes 45 can always be in contact with the surface of the plate, thereby ensuring the cleaning function of the cleaning brushes 45. During cleaning, the servo motor 46 drives one of the cleaning brushes 45 to rotate at high speed. Under the cooperation of the sprocket 410 and the chain 411, the two cleaning brushes 45 rotate at high speed, and the rotating cleaning brush 45 cleans the surface of the plate, and at the same time, the dust adhering to the cleaning brush 45 is thrown away, ensuring that the surface of the plate can be fully cleaned.

[0024] Reference Figure 1 and Figures 6-13, the dust stripping module 5 includes an access channel 51. The access channel 51 is connected to the other side of the channel B33, and the other side of the access channel 51 is connected to one side of the channel A8.

An assembly seat A56, an assembly seat C510, and an assembly seat B58 are sequentially installed in the outer cover 52. Positioning ports 513 are reserved on the walls of the assembly seat A56, the assembly seat C510, and the assembly seat B58. A stripping net 512 is assembled in the positioning ports 513. The assembly seat A56, the assembly seat C510, and the assembly seat B58 respectively match the notch A53, the notch B54, and the notch C55. A traction part 528 is installed in the outer cover 52. The traction part 528 drives the assembly seat A56, the assembly seat C510, and the assembly seat B58 to move. Assembly parts 514 are installed at the lower ends of the assembly seat A56 and the assembly seat B58. This dust stripping module 5 can temporarily replace the stripping net 512 on the assembly seat A56 and the assembly seat B58 with the stripping net 512 on the assembly seat C510, ensuring that the dust stripping module 5 can continuously strip dust during the production of cold-rolled steel sheets. And through the installed assembly parts 514, when the assembly seat A56 and the assembly seat B58 are received into the outer cover 52, the stripping net 512 on them can be tilted, so that the operator can disassemble and clean the stripping net 512. And after the assembly seat A56 and the assembly seat B58 leave the notch A53 and the notch C55, one side of the assembly seat A56 close to the access channel 51 is always embedded in the notch A53, and one side of the assembly seat B58 close to the access channel 51 is always embedded in the notch C55. After the walls of the assembly seat A56 and the assembly seat B58 are removed, it still has the function of sealing the notch A53 and the notch C55, thereby preventing the air with un-stripped dust from flowing out of the access channel 51. Similarly, after the assembly seat C510 leaves the notch B54, one side of it close to the access channel 51 is always embedded in the notch B54.

[0025] One side of the assembly seat A56 close to the traction part 528 is fixedly connected with a connecting rod A57. One side of the assembly seat B58 close to the traction part 528 is fixedly connected with a connecting rod B59. One side of the assembly seat C510 close to the traction part 528 is fixedly connected with a connecting rod C511, enabling the traction part 528 to control the assembly seat A56, the assembly seat B58, and the assembly seat C510 respectively through the connecting rod A57, the connecting rod B59, and the connecting rod C511.

[0026] A rectangular opening is reserved on one side of the assembly seat C510. The stripping net 512 is assembled in the positioning port 513 on the assembly seat C510 through the rectangular opening. Through the installed rectangular opening, the operator can embed the stripping net 512 into the positioning port 513 on the assembly seat C510, and the assembly is very convenient.

[0027] One side of the connecting rod A57 and the connecting rod B59 are both reserved with a variable port B520. An arched port 521 is reserved on the side wall of the variable port B520. The assembling part 514 includes a rotating disc 522. A number of teeth are reserved on the outer peripheral surface of the rotating disc 522.

The bending rod 524 is located on the side of the stop port 513. When the engaging rod 525 moves into the variable port B520, the linkage piece 526 drives the rotating disc 522 to rotate, and the rotating disc 522 drives the guiding rod A523 to rotate. The bending rod 524 is in a skewed state. The distance between the bending rod 524 and the stop port 513 becomes larger. At this time, the operator can insert the lower end of the peeling net 512 between the bending rod 524 and the stop port 513. Then the engaging rod 525 moves out of the variable port B520. The linkage piece 526 drives the rotating disc 522 to rotate, and the rotating disc 522 drives the guiding rod A523 to rotate. The bending rod 524 will lock the side wall of the peeling net 512, so that the peeling net 512 is fastened in the stop port 513.

[0028] A pair of stop boxes 515 are installed in the outer cover 52 in a mirror image manner. The pair of stop boxes 515 cooperate with the connecting rod A57 and the connecting rod B59 respectively. A variable port A516 is installed in the stop box 515. A track A517 is reserved on the side wall of the variable port A516. The track A517 includes a vertical end A518 and an inclined end A519.

When the connecting rod A57 and the connecting rod B59 move into the outer cover 52, the protruding rod 527 moves along the vertical end A518 towards the inclined end A519. When the protruding rod 527 moves into the inclined end A519, the entire engaging rod 525 moves into the variable port B520. Then when the connecting rod A57 and the connecting rod B59 are received in the outer cover 52, the bending rod 524 is in a skewed state. At this time, it is convenient for the operator to assemble and disassemble the peeling net 512.

[0029] The traction part 528 includes a traction platform 529, which is movably installed in the center of the outer cover 52. A square block 530 is installed on the side wall of the traction platform 529. A pair of track Bs 531 are reserved on the square block 530 in a mirror image manner. The track Bs 531 include a vertical end B532 and an inclined end B533. The vertical end B532 and the inclined end B533 are connected. The vertical end B532 is close to the connection channel 51. Each of the pair of track Bs 531 cooperates with a connecting rod A57 and a connecting rod B59 respectively. Connecting columns are installed on the side walls of the connecting rod A57 and the connecting rod B59. A boss is movably installed in each of the pair of track Bs 531. A connecting strip 534 is connected between the center of the boss and the side wall of the connecting column through a rotating column. A strip-shaped groove 538 is reserved on the inner surface side wall of the outer cover 52. One side of the boss is movably installed in the strip-shaped groove 538. The strip-shaped groove 538 is located in the center of the inner side of the outer cover 52. When the traction platform 529 pulls the square block 530 and continuously approaches the connection channel 51, one side of the boss slowly changes from the vertical end B532 to the inclined end B533. The inclined end B533 has a pressing effect on one side of the changing boss, and the strip-shaped groove 538 can restrict the connecting strip 534 to ensure that the distance between the boss and the connection channel 51 remains unchanged. Then, when the inclined end B533 presses on one side of the boss, one side of the boss changes in the strip-shaped groove 538. When the entire traction platform 529 changes towards the connection channel 51, the track B531 can guide the boss. When the boss changes in the inclined end B533 and the square block 530 changes towards the connection channel 51, the boss slowly changes towards the center of the square block 530. The connecting strip 534 on one side of the boss changes towards the center of the square block 530, and the connecting strip 534 on one side of the connecting column will change towards the outer cover 52, and then the mounting seat A56 and the mounting seat B58 are received into the outer cover 52.

[0030] A receiving cavity 535 is reserved in the traction platform 529. A guiding rod B536 is movably installed in the receiving cavity 535. One side of the guiding rod B536 passes through the traction platform 529, and one side of the guiding rod B536 is fixedly connected to the connecting rod C511. A deformation member 537 is installed on the outer peripheral surface of the guiding rod B536 and between the connecting rod C511 and the traction platform 529. An electric telescopic rod is installed at the upper end of the outer cover 52. The movable end of the electric telescopic rod is connected to the traction platform 529. The electric telescopic rod can pull the traction platform 529 to change in the outer cover 52. When the entire traction platform 529 changes towards the connection channel 51, the entire mounting seat C510 is inserted into the notch B54, and then the traction platform 529 continues to change towards the connection channel 51. Due to the constant position of the mounting seat C510, the change of the traction platform 529 towards one side of the connection channel 51 has a pressing effect on the deformation member 537, making the deformation member 537 shorter, and the guiding rod B536 is received into the receiving cavity 535.

[0031] During operation, when the electric telescopic rod pulls the entire traction table 529 to move towards one side of the connection channel 51, the entire mounting seat C510 is inserted into the notch B54. At this moment, the boss moves inside the vertical end B532, and then the traction table 529 continues to move towards one side of the connection channel 51. Due to the constant orientation of the mounting seat C510, the movement of the traction table 529 towards one side of the connection channel 51 exerts a pressing force on the deformable part 537, causing the deformable part 537 to become shorter and guiding the guide rod B536 to be received into the accommodation cavity 535. At this moment, the boss moves inside the inclined end B533, and the boss slowly moves towards the center of the square block 530. The connecting strip 534 on one side of the boss moves towards the center of the square block 530, and the connecting strip 534 on one side of the connecting column moves towards the outer cover 52, thereby receiving the mounting seat A56 and the mounting seat B58 into the outer cover 52. Then, during the movement of the connecting rod A57 and the connecting rod B59 towards the outer cover 52, the protruding rod 527 moves along the vertical end A518 towards the inclined end A519. After the protruding rod 527 moves into the inclined end A519, the entire embedding rod 525 moves towards the moving port B520. Then, when the connecting rod A57 and the connecting rod B59 are received into the outer cover 52, the linkage piece 526 pulls the rotating disc 522 to rotate, and the rotating disc 522 pulls the guide rod A523 to rotate. The bending rod 524 is in an inclined state, and the distance between the bending rod 524 and the stop port 513 becomes larger. At this time, it is convenient for the operator to assemble and disassemble the peeling net 512. During this period, the mounting seat C510 first peels off the dusty air inside the connection channel 51, and then the mounting seat A56 and the mounting seat B58 move into the outer cover 52. Then, after the peeling net 512 on the mounting seat A56 and the mounting seat B58 is cleaned, the electric telescopic rod pulls the traction table 529 to move back. At this moment, the deformation effect of the deformable part 537 positions the mounting seat C510 in the notch B54, and while the boss moves in the inclined end B533, it pulls and inserts the mounting seat A56 and the mounting seat B58 into the notch A53 and the notch C55 respectively. Then the traction table 529 continues to retract, and the mounting seat C510 moves out of the notch B54 and is received into the outer cover 52.
