Description

Technical Field

[0001] The utility model relates to the technical field of slitting machines, in particular to a stainless steel strip slitting machine. Background Technique

[0002] The stainless steel strip used for the production of mobile phone backplates, as the name implies, is a metal strip with stainless steel characteristics. It is a metal material with high corrosion resistance, high strength, high thermal stability and high processing performance, and is widely used in various industrial fields. The stainless steel strip is usually made of high carbon steel or alloy steel through a series of processing and treatment, with a smooth and bright surface, and excellent rust and oxidation resistance. After the production of the stainless steel strip, a slitting machine is usually required to perform slitting operations on the stainless steel strip to meet different market demands.

[0003] For example, a stainless steel strip slitting machine with the Chinese patent application number CN202321356400.7 includes a workbench, a support table is provided on the workbench, and a tension roller group is provided on the support table; a cutting knife group is provided downstream of the tension roller group, and the cutting knife group includes an upper blade and a lower blade. Through the structural design, the utility model achieves a good stretching effect while restricting the position of the steel strip, effectively preventing the steel strip from undulating and shifting left and right, resulting in deviation of the slitting accuracy.

Detailed Embodiments

[0026] To enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] As Figures 1-6 shown, the present utility model provides a stainless steel strip slitting machine, which includes a slitting machine body 1 and a lead curtain 9 fixedly arranged on one side of the slitting machine body 1. Both the front and rear side walls at both ends inside the slitting machine body 1 are connected with mounting plates 8 through bearings. The same two mounting plates 8 on the same side are detachably connected with the same rotating shaft 6. A winding shaft 3 is sleeved outside one rotating shaft 6, and a stainless steel strip roller shaft 2 is sleeved outside the other rotating shaft 6. A first motor 7 is fixedly arranged at the rear of the slitting machine body 1. The rear ends of the two rotating shafts 6 are connected through a belt transmission assembly. The output shaft of the first motor 7 penetrates through the slitting machine body 1 and is fixedly connected with the rear end of one of the rotating shafts 6, facilitating the first motor 7 to control the mutual rotation of the two rotating shafts 6. A front door is hingedly connected to one end of the front side of the slitting machine body 1. Moving wheels 11 are fixedly arranged at the four corners of the bottom of the slitting machine body 1, facilitating the movement of the present utility model.

[0028] As Figures 1-3 , 5, 6 shown, a slitting assembly 5 is arranged at the top of the slitting machine body 1, facilitating the precise slitting of the stainless steel strip into different sizes. The slitting assembly 5 includes a threaded rod 51. Another side inside the slitting machine body 1 is provided with a slotted groove, and both the front and rear ends of the threaded rod 51 are connected between the front and rear ends inside the slotted groove through bearings. A threaded block 52 is threadedly connected to the threaded rod 51, and the outer wall of the threaded block 52 contacts the inner wall of the slotted groove. A laser displacement sensor 53 is fixedly arranged at the bottom of the threaded block 52, facilitating the movement of the threaded block 52 and the laser displacement sensor 53 along the threaded rod 51. Three roller shafts 55 are arranged at the bottom of the threaded rod 51. Both the front and rear ends of the three roller shafts 55 are connected to the front and rear sides inside the slitting machine body 1 through bearings.

[0029] The rear ends of the three roller shafts 55 penetrate through the slitting machine body 1 and are all fixedly provided with gears 56. Both of the bottom two gears 56 are meshed with the top one gear 56, and the bottom two gears 56 do not contact each other, facilitating the mutual rotation of the three gears 56. The rear end of the threaded rod 51 and the rear end of the top roller shaft 55 are connected through a belt transmission assembly. A plurality of sliding cylinders 57 are slidably arranged on the top roller shaft 55. A slitting knife 58 is fixedly arranged on the sliding cylinder 57, and a bolt for fixing between the sliding cylinder 57 and the roller shaft 55 is threadedly connected to the sliding cylinder 57. A second motor 54 is fixedly arranged at the rear of the slitting machine body 1. The output shaft of the second motor 54 penetrates through the slitting machine body 1 and is fixedly connected with the rear end of the top roller shaft 55.

[0030] On the other side of the top of the slitting body 1, a scale 59 is fixedly arranged for facilitating the observation of the position of the laser displacement sensor 53. On the front side of the slitting body 1, a warning light 12 is fixedly arranged. On the front side of the slitting body 1, a controller 10 is fixedly arranged for controlling the warning light 12, the second motor 54, the first motor 7 and the laser displacement sensor 53.

[0031] By arranging the slitting assembly 5, the stainless steel strip roller 2 sleeved with the stainless steel strip coil and the take-up reel 3 are respectively passed through the rotating shaft 6, and then the rotating shaft 6 is fixed to the mounting plate 8 through bolts and other parts.

[0032] Then, according to the requirements of the stainless steel strip slitting size, the operator operates the controller 10 to control the second motor 54 to work. The second motor 54 drives the threaded rod 51 to rotate, so that the threaded block 52 drives the laser displacement sensor 53 to move back and forth along the threaded rod 51, and the position between the laser displacement sensor 53 and the adjacent scale 59 is observed in real time through the scale 59. When reaching the required position, the second motor 54 is turned off. This position is the size of the stainless steel strip slitting. At this time, the laser displacement sensor 53 detects the distance between it and the surface of the roller 55.

[0033] Then, the bolt on the sliding cylinder 57 is unscrewed, and the sliding cylinder 57 is pushed to slide along the roller 55 until the sliding cylinder 57 slides to the bottom of the laser displacement sensor 53. At this time, the laser displacement sensor 53 detects the distance between it and the slitting knife 58 on the sliding cylinder 57. Therefore, the detected distance of the laser displacement sensor 53 changes. Then the laser displacement sensor 53 transmits a signal to the controller 10, and the controller 10 controls the warning light 12 to light up. The operator immediately stops sliding the sliding cylinder 57 and tightens the bolt on it to fix the position of the sliding cylinder 57, so as to facilitate the subsequent precise slitting of stainless steel strips of different sizes and improve the applicable range.

[0034] Open the front door, pass one end of the stainless steel strip coil on the stainless steel strip roller 2 through between the three rollers 55 and fix it to the top of the take-up reel 3. At the same time, the stainless steel strip contacts with multiple slitting knives 58. Then, the first motor 7 is rotated to drive the stainless steel strip roller 2 to rotate to unwind the stainless steel strip coil. At the same time, the second motor 54 is driven to rotate the three rollers 55. Through the transmission of the gear 56, the two bottom rollers 55 rotate in the same direction as the stainless steel strip roller 2 to guide the stainless steel strip, and the top roller 55 drives the slitting knife 58 to rotate in the opposite direction to the stainless steel strip to slit the stainless steel strip into multiple strips. Then the rotating shaft 6 rotates to wind up the slit stainless steel strip.

[0035] Such as Figures 1-4As shown in the figure, a slag removal component 4 is provided at the top of the slitting body 1, which is used to blow off the residues generated by the stainless steel strip during the slitting process. The slag removal component 4 includes a blower 41, and the blower 41 is controlled to work by a controller 10. The blower 41 is fixedly arranged on one side of the top of the slitting body 1. Two connecting pipes 42 distributed front and back are fixedly arranged at the bottom of the blower 41. The bottom ends of the two connecting pipes 42 penetrate through the top of the slitting body 1 and are respectively fixedly provided with corrugated pipes 43. The same blowing pipe 44 is fixedly arranged between the bottom ends of the two corrugated pipes 43. A plurality of uniformly distributed spray holes 45 are formed at the bottom of the blowing pipe 44. Guide platforms 48 are fixedly arranged on both sides of the bottom of the slitting body 1. An opening is formed at the center of the bottom of the slitting body 1, and a draw frame 46 is slidably clamped in the opening. A breathable net 47 is fixedly arranged inside the draw frame 46, which is convenient for the air flow inside the slitting body 1 and at the same time collects the residues during slitting.

[0036] By setting the slag removal component 4, during the process of slitting the stainless steel strip, the operator operates the controller 10 to control the blower 41 to work. The blower 41 sends the air into the two corrugated pipes 43 and the blowing pipe 44 through the two connecting pipes 42. According to the position of the stainless steel strip inside the slitting body 1, the operator manually pulls the two corrugated pipes 43 to contract or stretch, so that the blowing pipe 44 is placed on the top of the stainless steel strip, which is convenient for blowing air to the top of the stainless steel strip through a plurality of spray holes 45, and finally blows it to the outside through the breathable net 47 to form an air flow, thereby realizing blowing off and collecting the residues generated during the slitting process of the stainless steel strip on the top of the breathable net 47, avoiding affecting the quality of the stainless steel strip winding, and improving the quality of the stainless steel strip slitting.
