Description

Technical Field

[0001] This utility model relates to the field of steel plate processing technology, specifically a continuous steel plate slitting and cutting device. Background Technology

[0002] A steel plate slitting and cutting device is used for slitting steel coils. Typically, the steel plate coil is first unwound and guided by a guide device to be accurately conveyed to the cutting mechanism. The cutting mechanism's cutter shaft rotates at high speed under the drive of the drive device, and the blades cut the steel plate longitudinally, cutting the wide steel plate into strips of the required width. The cut steel strips are then wound into coils by a winding mechanism, completing the entire slitting and cutting process. Usually, the edges of the cut steel strips are sharp, and to ensure safety during subsequent processing, gloves are often required when handling and transferring them.

The pushing device includes a first adjusting plate, a first guide roller, a conveying roller, a first gear, a second gear, a limiting post, and an extension block. Multiple first adjusting plates are fixedly installed on the cabinet. The first guide roller is rotatably connected to the first adjusting plate via a rotating shaft. The conveying roller is rotatably connected to the cabinet via a rotating shaft. The first gear is rotatably connected to the front side wall of the cabinet via a rotating shaft. The second gear is fixedly installed on the rotating shaft of the conveying roller and is located below the first gear. The first gear and the second gear mesh with each other. Two limiting posts are fixedly installed on the first gear, and the extension block is fixedly installed on the second gear.

[0010] Furthermore, the second gear has no teeth at the end near the extension block;

[0011] Furthermore, the pushing device also includes: a drive motor, a third gear and a fourth gear. The drive motor is fixedly mounted on the upper side of the cabinet via a motor bracket. The third gear is fixedly mounted on the output shaft of the drive motor. The fourth gear is rotatably connected to the front side wall of the cabinet via a rotating shaft. The fourth gear and the third gear mesh with each other.

[0012] Furthermore, the third gear meshes with the first gear;

[0013] Furthermore, the slitting device includes: a second guide roller, circular blades, and a fifth gear. The second guide roller is rotatably connected to the middle side of the cabinet via a rotating shaft. Multiple circular blades are fixedly mounted on the second guide roller. The fifth gear is fixedly mounted on the rotating shaft of the second guide roller. The fifth gear and the fourth gear mesh with each other.

[0014] Furthermore, the slitting device also includes: a second adjusting plate and a third guide roller, wherein multiple second adjusting plates are fixedly installed on the cabinet, and the third guide roller is rotatably connected to the second adjusting plate via a rotating shaft;

[0015] Furthermore, the continuous cutting device includes: a crankshaft, a connecting rod, a guide rail, a slider, a sliding bracket, and a reduction motor. The crankshaft is rotatably connected to the cabinet. One end of the connecting rod is hinged to the middle side of the crankshaft. Multiple guide rails are fixedly installed on the cabinet. The slider is slidably connected to the guide rail. The sliding bracket is fixedly installed on the slider. The end of the connecting rod away from the crankshaft is hinged to the middle side of the sliding bracket. The reduction motor is fixedly installed on the upper side of the cabinet.

[0018] Compared with the prior art, the beneficial effects of this utility model are: 1. By adjusting the first adjusting plate of the pushing device, this utility model makes the distance between the first guide roller and the conveying roller on the first adjusting plate adapt to the thickness of the steel plate. The rotation of the first gear drives the rotation of the second gear. When the extension block of the second gear rotates to the position of the first gear, the second gear is toothless when it is close to the position of the first gear. The second gear stops rotating. Through the cooperation of the extension block and the limiting column, the second gear continues to rotate. When the toothed position of the second gear rotates to the position of the first gear, the first gear and the second gear continue to mesh and drive each other. After the second gear rotates continuously, it stops for a period of time and then continues to rotate. The rotation of the second gear drives the conveying roller to rotate. After the conveying roller rotates continuously, it stops for a period of time and then continues to rotate. This is conducive to realizing intermittent conveying of steel plates.

[0019] 2. The sliding bracket moves up and down, driving the transverse bracket to move up and down as well. Under the action of the sliding rod and spring, the transverse bracket stops moving downward after pressing down on the steel plate. At this time, the spring undergoes elastic deformation, pressing down on the steel plate. The sliding bracket continues to move downward, driving the blade downward. The upper blade moves downward to cooperate with the lower blade. The steel plate is clamped at the same time as it stops between the upper and lower blades. Then, the steel coil is cut transversely, which is beneficial for continuously cutting the slit steel plate into the preset length. Attached Figure Description

[0027] 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.

[0028] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0029] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-6A continuous steel plate slitting and cutting device includes a cabinet 1, and further includes a pushing device 2, a slitting device 3, and a continuous cutting device 4. The pushing device 2 is installed on the right side of the cabinet 1, the slitting device 3 is installed in the middle of the cabinet 1, and the continuous cutting device 4 is installed on the left side of the cabinet 1. The pushing device 2 includes a first adjusting plate 21, a first guide roller 22, a conveying roller 23, a first gear 24, a second gear 25, a limiting post 26, and an extension block 27. Multiple first adjusting plates 21 are fixedly installed on the cabinet 1. The first guide roller 22 is rotatably connected to the first adjusting plate 21 via a rotating shaft. The conveying roller 23 is rotatably connected to the cabinet 1 via a rotating shaft. The first gear 24 is rotatably connected to the front side wall of the cabinet 1 via a rotating shaft. The second gear 25 is fixedly installed on the rotating shaft of the conveying roller 23. The second gear 25 is located below the first gear 24. The first gear 24 and the second gear 25 mesh with each other. Two limiting posts 26 are fixedly installed on the first gear 24. The extension block 27 is fixedly installed on the second gear 25.

[0030] The pushing device 2 pushes the steel plate coil to the position of the slitting device 3. The slitting device 3 vertically slits the steel plate, and the continuous cutting device 4 horizontally cuts the strip steel plate formed after slitting to form steel strips of a specific length for subsequent product processing.

[0031] The second gear 25 has no teeth at the end near the extension block 27.

[0032] By adjusting the first adjusting plate 21 of the pushing device 2, the distance between the first guide roller 22 and the conveying roller 23 on the first adjusting plate 21 is adapted to the thickness of the steel plate. The first gear 24 rotates, driving the second gear 25 to rotate. When the extension block 27 of the second gear 25 rotates to the position of the first gear 24, the second gear 25 is toothless when it is close to the position of the first gear 24, and the second gear 25 stops rotating. Through the cooperation of the extension block 27 and the limiting column 26, the second gear 25 continues to rotate. The toothed position of the second gear 25 rotates to the position of the first gear 24. At this time, the first gear 24 and the second gear 25 continue to mesh and drive each other. After the second gear 25 rotates continuously, it stops for a period of time and then continues to rotate. The rotation of the second gear 25 drives the conveying roller 23 to rotate, which is beneficial to realize that the conveying roller 23 rotates continuously, stops for a period of time, and then continues to rotate.

[0033] Example 2: In some embodiments, such as Figures 1-6In a preferred embodiment of the present invention, the pushing device 2 further includes a drive motor 28, a third gear 29 and a fourth gear 210.

The fourth gear 210 is rotatably connected to the front side wall of the cabinet 1 by a rotating shaft. The fourth gear 210 and the third gear 29 mesh with each other.

[0034] The rotation of the output end of the drive motor 28 drives the third gear 29 to rotate, and the rotation of the third gear 29 drives the fourth gear 210 to rotate.

[0035] The third gear 29 and the first gear 24 mesh with each other.

[0036] The rotation of the third gear 29 drives the rotation of the first gear 24.

[0037] The slitting device 3 includes: a second guide roller 31, a circular blade 32, and a fifth gear 33. The second guide roller 31 is rotatably connected to the middle side of the cabinet 1 via a rotating shaft. A plurality of the circular blades 32 are fixedly installed on the second guide roller 31. The fifth gear 33 is fixedly installed on the rotating shaft of the second guide roller 31. The fifth gear 33 and the fourth gear 210 mesh with each other.

[0038] The fourth gear 210 drives the fifth gear 33 of the slitting device 3 to rotate, the rotation of the fifth gear 33 drives the second guide roller 31 to rotate, and the rotation of the second guide roller 31 drives the circular blade 32 to rotate.

[0039] The slitting device 3 further includes: a second adjusting plate 34 and a third guide roller 35. Multiple second adjusting plates 34 are fixedly installed on the cabinet 1, and the third guide roller 35 is rotatably connected to the second adjusting plate 34 via a rotating shaft.

[0040] The second adjusting plate 34 makes the distance between the second guide roller 31 and the circular blade 32 on the second adjusting plate 34 adapt to the thickness of the steel plate. The circular blade 32 rotates and cooperates with the third guide roller 35 to cut the steel plate pushed by the pushing device 2 into strips.

[0041] The continuous cutting device 4 includes: a crankshaft 41, a connecting rod 42, a guide rail 43, a slider 44, a sliding bracket 45, and a reduction motor 46. The crankshaft 41 is rotatably connected to the cabinet 1. One end of the connecting rod 42 is hinged to the middle side of the crankshaft 41. Multiple guide rails 43 are fixedly installed on the cabinet 1. The slider 44 is slidably connected to the guide rails 43. The sliding bracket 45 is fixedly installed on the slider 44. The end of the connecting rod 42 away from the crankshaft 41 is hinged to the middle side of the sliding bracket 45. The reduction motor 46 is fixedly installed on the upper side of the cabinet 1. The output shaft of the reduction motor 46 is fixedly connected to the rotating shaft of the crankshaft 41.

[0042] The rotation of the output end of the geared motor 46 drives the crankshaft 41 to rotate. The rotation of the crankshaft 41 drives the connecting rod 42 to move up and down. The up and down movement of the connecting rod 42 drives the sliding bracket 45 to move up and down under the constraint of the guide rail 43 and the slider 44, which is conducive to the continuous up and down movement of the sliding bracket 45.

[0043] The continuous cutting device 4 further includes: an irregularly shaped bracket 47 and a limiting plate 48. The irregularly shaped bracket 47 is fixedly installed on the left side of the cabinet 1, and the limiting plate 48 is fixedly installed on the upper side of the cabinet 1. The limiting plate 48 is located on the upper side of the irregularly shaped bracket 47 and is used to limit the steel plate so that it does not move too far up or down.

[0044] The continuous cutting device 4 further includes: an upper blade 49, a lower blade 410, a sliding rod 411, a transverse support 412, and a spring 413. The upper blade 49 is fixedly installed on the left side of the sliding support 45, the lower blade 410 is fixedly installed on the irregular support 47, a plurality of sliding rods 411 are slidably connected to the lower side of the sliding support 45, the transverse support 412 is fixedly installed on the lower side of the sliding rods 411, and the spring 413 is disposed on the sliding rods 411. One end of the spring 413 is in close contact with the sliding support 45, and the other end of the spring 413 is in close contact with the transverse support 412.

[0045] The sliding bracket 45 moves up and down, driving the transverse bracket 412 to move up and down. Under the action of the sliding rod 411 and the spring 413, the transverse bracket 412 stops moving downward after pressing the steel plate. At this time, the spring 413 undergoes elastic deformation, pressing the steel plate down. The sliding bracket 45 continues to move downward, driving the blade to move downward. The upper blade 49 moves downward to cooperate with the lower blade 410. While the steel plate is being transported between the upper blade 49 and the lower blade 410, it is clamped and then the steel coil is cut transversely. This is beneficial for continuously cutting the slit steel plate into a preset length.
