Description

Technical Field

[0001] This invention belongs to the field of stainless steel strip technology, specifically, it relates to a stainless steel strip slitting machine. Background Technology

[0002] Stainless steel strip is an extension of a thinner stainless steel sheet. During production, stainless steel strip requires a slitting machine for cutting. The stainless steel strip slitting machine can unwind and slit the metal coil, and finally rewind it into a strip of the required width.

[0003] When using a stainless steel strip slitting machine to longitudinally cut stainless steel coils, the stainless steel coils are placed on the conveyor rollers of the slitting machine. During the conveying process, the stainless steel coils are longitudinally cut into several narrow strips of stainless steel strips. Finally, the narrow strips are rewound into coils to obtain stainless steel strips.

[0004] However, when existing stainless steel strips are slit, a downward force is often applied to the strip during the slitting process. This can easily cause deformation at the edges of the strip after slitting.

The following embodiments are used to illustrate the present invention.

[0040] Example 1:

A stainless steel strip 4 is conveyed on the conveyor body 11. After being slitted by the cutting assembly 112, the stainless steel strip 4 is divided into a first strip stainless steel strip 41 and a second strip stainless steel strip 42. A protective shell 14 is provided on one side of the first concave mounting plate 12 and the second concave mounting plate 13. An upper guide assembly 15 and a lower guide assembly 151 are provided inside the first concave mounting plate 12. The first strip stainless steel strip 4... The first and second stainless steel strips 42 are located on opposite sides of the upper guide assembly 15 and the lower guide assembly 151, respectively. The inner cavity of the second concave mounting plate 13 is provided with an upper L-shaped fixing plate 33 and a lower L-shaped fixing plate 331. The upper grinding assembly 333 and the lower grinding assembly 334 are respectively staggered on the opposite side walls of the upper L-shaped fixing plate 33 and the lower L-shaped fixing plate 331. The upper grinding assembly 333 and the lower grinding assembly 334 are used to grind the sides of the first stainless steel strip 41 and the second stainless steel strip 42. A driving assembly is provided inside the protective housing 14. The driving assembly is used to adjust the positions of the upper guide assembly 15 and the lower guide assembly 151, as well as the upper grinding assembly 333 and the lower grinding assembly 334. By dividing the stainless steel strip body 4 into a first strip stainless steel strip 41 and a second strip stainless steel strip 42, with the first strip stainless steel strip 41 located on top and the second strip stainless steel strip 42 located on the bottom, the deformation of the stainless steel strip body 4 after cutting at the edge can be reduced to a certain extent when it is cut by the cutting component 112.

[0042] like Figures 1 to 6 As shown, in a specific embodiment, mounting brackets 1 are provided on both sides of the conveyor body 11, and a positioning component 111 is also provided on the top of the conveyor body 11. The positioning component 111 is used to position the belt 31. In this configuration, the components of the conveyor body 11 are defined.

[0043] Example 2:

[0044] The difference between Embodiment 1 and this embodiment is that: Figures 1 to 7 and Figure 9 as well as Figure 11 and Figure 13As shown, a stainless steel strip slitting machine has a first rectangular slot 121 extending through the first concave mounting plate 12 near the protective housing 14. The inner walls of the first rectangular slot 121 have first sliding grooves 122 on opposite sides, symmetrically arranged. Each of the two first sliding grooves 122 has a first slider 123 slidably mounted within its inner cavity, also symmetrically arranged. The upper and lower side walls of the inner cavity of the first rectangular slot 121 are each equipped with a first return spring 124, with the opposite ends of the first return springs 124 respectively mounted on the upper guide assembly 15 and the lower guide assembly 151. This configuration ensures vertical movement on both the upper and lower guide assemblies 15 and 151.

[0045] like Figures 1 to 7 and Figure 9 as well as Figure 11 and Figure 13 As shown, in a specific embodiment, the first concave mounting plate 12 has a sliding groove 125 on the side wall away from the protective housing 14, and a sliding block 126 is provided inside the sliding groove 125. This arrangement ensures that the upper guide assembly 15 and the lower guide assembly 151 can move.

[0046] like Figures 1 to 9 and Figure 13 As shown, further, a second rectangular slot 131 is provided through one side wall of the second concave mounting plate 13 near the protective housing 14. Second sliding grooves 132 are provided on opposite side walls of the inner cavity of the second rectangular slot 131. The two second sliding grooves 132 are symmetrical. Second sliders 133 are slidably mounted within the inner cavities of both second sliding grooves 132. The two second sliders 133 are also symmetrical. Second return springs 134 are provided on both the upper and lower side walls of the second rectangular slot 131. The opposite ends of the two second return springs 134 are respectively mounted on the upper grinding assembly 333 and the lower grinding assembly 334. This configuration ensures that the upper grinding assembly 333 and the lower grinding assembly 334 can move vertically.

[0047] like Figures 1 to 9 and Figure 13 As shown, furthermore, a movable slot 135 is provided on the side of the second concave mounting plate 13 away from the protective housing 14, and a movable block 136 is slidably disposed inside the movable slot 135. In this configuration, the upper grinding assembly 333 and the lower grinding assembly 334 can move.

[0048] Example 3:

[0049] The difference between Embodiment 2 and this embodiment is that: Figures 5 to 7 and Figures 9 to 11 as well as Figure 1As shown, a stainless steel strip slitting machine includes a drive assembly comprising a servo motor 2, which is disposed within the inner cavity of a protective housing 14. A maintenance door 141 is provided on one side wall of the protective housing 14. A rotating rod 21 is provided at the output end of the servo motor 2. A first irregular plate 22 is fixedly connected to the end of the rotating rod 21 away from the servo motor 2. A first irregular groove 221 is provided on the outer wall of the first irregular plate 22. Two mutually symmetrical first sliding balls 222 are slidably disposed within the inner cavity of the first irregular groove 221. A first L-shaped mounting plate 223 is provided on each of the two first sliding balls 222. The two first L-shaped mounting plates 223 are mutually symmetrical, and one end of each first L-shaped mounting plate 223 is disposed on a second slider 133. In this setup, the installation position and components of the drive assembly are determined, ensuring that by controlling the operation of the servo motor 2, the servo motor 2 can drive the rotating rod 21 to rotate. When the rotating rod 21 rotates, it can drive the first irregular plate 22 to rotate. When the first irregular plate 22 rotates, it can drive the first sliding ball 222 through the first irregular slot 221. With the assistance of the first L-shaped mounting plate 223, the second slider 133, and the second slide groove 132, it can drive the upper guide component 15 and the lower guide component 151 set on the second slider 133 to move in opposite directions until the first strip stainless steel strip 41 is straightened by the upper guide component 15 and the lower guide component 151.

[0050] like Figures 5 to 7 and Figures 9 to 11 as well as Figure 13 As shown in the specific embodiment, the rotating rod 21 is further provided with a first pulley 3, the first pulley 3 is provided with a belt 31, the belt 31 is further provided with a second pulley 311, and a rotating rod 32 is provided through the second pulley 311. In this configuration, it is ensured that when the rotating rod 21 rotates, it can also drive the first pulley 3 to rotate, and when the first pulley 3 rotates, it can drive the second pulley 311 to rotate through the belt 31.

[0051] like Figures 5 to 7 and Figures 9 to 11 as well as Figure 1As shown, further, one end of the rotating rod 32 is rotatably mounted on the inner wall of the protective housing 14, and the other end of the rotating rod 32 is provided with a second irregular plate 321. The second irregular plate 321 is provided with a second irregular groove 322. Two mutually symmetrical second sliding balls 323 are slidably arranged in the inner cavity of the second irregular groove 322. Each of the two second sliding balls 323 is provided with a second L-shaped mounting plate 324. The two second L-shaped mounting plates 324 are mutually symmetrical. An upper L-shaped fixing plate 33 and a lower L-shaped fixing plate 331 are respectively provided at the ends of the two second L-shaped mounting plates 324 away from the second sliding balls 323. In this configuration, it is ensured that when the rotating rod 32 rotates, it can drive the second irregular plate 321 to rotate. When the second irregular plate 321 rotates, it can drive the second sliding ball 323 to move vertically in opposite directions with the assistance of the second irregular groove 322, the second L-shaped mounting plate 324, the first sliding groove 122, and the first slider 123.

[0052] like Figures 5 to 7 and Figures 9 to 11 as well as Figure 1 As shown, furthermore, a first return spring 124 is provided on the opposite side wall of the upper L-shaped fixing plate 33 and the lower L-shaped fixing plate 331. Multiple placement components 332 are respectively provided on the side walls of the upper L-shaped fixing plate 33 and the lower L-shaped fixing plate 331, and each placement component 332 is provided with an upper grinding component 333 and a lower grinding component 334. This configuration ensures that the lower L-shaped fixing plate 331 can be reset, and determines the positions of the upper grinding component 333 and the lower grinding component 334.

[0053] The implementation principle of the stainless steel strip slitting machine of the present invention is as follows:

[0054] First, the stainless steel strip body 4 is transported. When the stainless steel strip body 4 is longitudinally cut by the cutting component 112, the multiple first strip stainless steel strips 41 and multiple second strip stainless steel strips 42 are placed on the upper guide component 15 and the lower guide component 151 respectively, and the stainless steel strip body 4 is unwound until the first strip stainless steel strips 41 and the second strip stainless steel strips 42 move to the winding component. At this time, the winding component winds the first strip stainless steel strips 41 and the second strip stainless steel strips 42 (the unwinding of the stainless steel strip body 4 and the winding of the first strip stainless steel strips 41 and the second strip stainless steel strips 42 by the winding component are both existing technologies).

[0055] At this time, by controlling the operation of the servo motor 2, the servo motor 2 will be able to drive the rotating rod 21 to rotate. When the rotating rod 21 rotates, it will be able to drive the first irregular plate 22 to rotate. When the first irregular plate 22 rotates, it will be able to drive the first sliding ball 222 through the first irregular slot 221 to drive the upper guide component 15 and the lower guide component 151 set on the second slider 133 to move in opposite directions with the assistance of the first L-shaped mounting plate 223, the second slider 133 and the second slide groove 132, until the first strip stainless steel strip 41 is straightened by the upper guide component 15 and the lower guide component 151 (wherein the position of the first sliding ball 222 in the attached drawing of the specification is the position in the straightened state).

[0056] Simultaneously, when the rotating rod 21 rotates, it can also drive the first pulley 3 to rotate. When the first pulley 3 rotates, it can drive the second pulley 311 to rotate via the belt 31 (because the second pulley 311 is equipped with a rotating rod 32, the rotation of the second pulley 311 can be ensured with the assistance of the rotating rod 32). When the rotating rod 32 rotates, it can drive the second irregular plate 321 to rotate. When the second irregular plate 321 rotates, it can drive the second sliding ball 323 to rotate vertically in opposite directions with the assistance of the second irregular groove 322, the second L-shaped mounting plate 324, the first sliding groove 122, and the first slider 123. The movement (where the first pulley 3 is a small pulley and the second pulley 311 is a large pulley, so when the first pulley 3 rotates once, the second pulley 311 rotates more times, thus ensuring that the upper guide assembly 15 and the lower guide assembly 151 move faster, while the upper L-shaped fixing plate 33 and the lower L-shaped fixing plate 331 move slower, and always ensure that the upper grinding assembly 333 and the lower grinding assembly 334 set on the upper L-shaped fixing plate 33 and the lower L-shaped fixing plate 331 can grind the edges of the first strip stainless steel strip 41 and the second strip stainless steel strip 42 respectively, thus reducing the burrs of the first strip stainless steel strip 41 and the second strip stainless steel strip 42 after cutting to a certain extent).

[0057] By dividing the stainless steel strip body 4 into a first strip stainless steel strip 41 and a second strip stainless steel strip 42, with the first strip stainless steel strip 41 located on top and the second strip stainless steel strip 42 located on the bottom, the deformation of the stainless steel strip body 4 after cutting at the edge can be reduced to a certain extent when it is cut by the cutting component 112.
