[0027] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. However, the present invention can be implemented in a variety of different ways as defined and covered below.

[0028] Please refer to the attached drawings, which is a structural schematic diagram of a preferred embodiment of a cutting device and a slitting machine provided by the utility model.

[0029] A cutting device is used for cutting and slitting a steel strip. The cutting device comprises a mounting bracket 1, a knife seat 2, a fixed blade 3, a movable blade 4, an adjustment component 5 and a driving mechanism:

[0030] The mounting bracket 1 is used to support the knife seat 2;

[0031] An installation cavity is provided inside the knife seat 2, and the knife seat 2 is connected to a driving mechanism, which is used to drive the knife seat 2 to rotate. The fixed blades 3 are arranged axially on the outer wall of the knife seat 2, and installation grooves 8 are provided between adjacent fixed blades 3. The installation grooves 8 are connected to the installation cavity, and a movable blade 4 is movably provided in the installation groove 8. An adjustment component 5 is provided in the installation cavity, and the adjustment component 5 is slidably connected to the bottom end of the movable blade 4. The adjustment component 5 is used to adjust the distance that the top end of the movable blade 4 is exposed outside the installation groove 8.

[0032] The utility model divides the cutting blade into a fixed blade 3 and a movable blade 4, and adjusts the position of the movable blade 4 to adjust the overall density of the cutting blade, thereby adjusting the width of the strips. The adjustment operation is simple, efficient and low in cost. The fixed blades 3 are arranged on the outer wall of the blade holder 2, and the distance between each fixed blade 3 is fixed, so the width of the cut steel strip is fixed. A mounting groove 8 is provided between each fixed blade 3, and the movable blade 4 in the mounting groove 8 can be adjusted by the adjustment component 5 to expose the distance outside the mounting groove 8. When the adjustment component 5 pushes the movable blade 4 out to the outermost end of the mounting groove 8, the overall density of the cutting blade is doubled, thereby adjusting the distance between each cutting blade, that is, adjusting the width of the strips.

[0033] Preferably, please refer to Figure 2 As shown, the adjustment component 5 includes an adjustment column 10 and an adjustment plate 7. The adjustment column 10 is movably arranged in the installation cavity. A strip through hole is opened on the outer wall of the installation cavity. The first end of the adjustment plate 7 is connected to the adjustment column 10, and the second end of the adjustment plate 7 extends out of the outside of the strip through hole. The adjustment plate 7 is used to push the adjustment column 10 to move axially, and the adjustment plate 7 and the outer wall of the installation cavity are locked and limited by a locking component.

[0034] It can be understood that by pushing the adjustment column 10 to move back and forth along the axial direction of the knife seat 2 through the adjustment plate 7, the position of the movable blade 4 can be adjusted, thereby adjusting the overall density of the cutting blade, achieving rapid adjustment of the cutting strip width, and the operation is very convenient.

[0035] Preferably, please refer to Figure 1 As shown, the locking assembly includes a butterfly bolt, a limiting through hole is provided on the adjustment plate 7, and a limiting screw hole is provided on the outer wall of the installation cavity. The butterfly bolt is used to pass through the limiting through hole and cooperate with the limiting screw hole to fasten the adjustment plate 7 to the outer wall of the installation cavity.

[0036] It is understandable that the butterfly bolt can be conveniently tightened manually, and the adjustment plate 7 can be manually pushed and then manually locked by the butterfly bolt, which is conducive to improving the convenience of manual operation.

[0037] Preferably, please refer to Figure 1 As shown, the regulating column 10 is provided with limiting grooves 12 at intervals, and the side walls of the limiting grooves 12 are inclined structures.

[0038] It can be understood that the two sides of the limiting groove 12 are boss structures, and the bosses on the two sides of the limiting groove 12 are set as ejection platforms 11, and the ejection platforms 11 are used to eject the movable blade 4. Specifically, when the bottom end of the movable blade 4 falls into the limiting groove 12, the distance that the top end of the movable blade 4 is exposed outside the mounting groove 8 is short. At this time, the height of the top end of the movable blade 4 is shorter than the height of the fixed blade 3, and the movable blade 4 does not play a cutting role; when the adjustment column 10 is pushed, the inclined side wall of the limiting groove 12 gradually ejects the bottom of the movable blade 4, and finally the ejection platform 11 ejects the movable blade 4 to the outermost end and is flush with the fixed blade 3. At this time, the movable blade 4 also plays a cutting role, and the shorter distance between the movable blade 4 and the fixed blade 3 is the width of the strip. In this way, the density of the entire cutting blade can be conveniently adjusted by adjusting the column 10, and then the width of the strip can be adjusted.

[0039] In one embodiment, a circular array of movable blades 4 is arranged in the mounting groove 8, and a limit baffle 14 is provided on each movable blade 4. A first compression spring 13 is provided between the limit baffle 14 and the inner wall of the mounting cavity. The first compression spring 13 is used to provide an elastic force to push the movable blade 4 radially inward.

[0040] It can be understood that after the adjusting column 10 pushes out the movable blade 4, if the width of the strip needs to be increased, that is, the movable blade 4 needs to be retracted, it is only necessary to push the adjusting column 10 so that the bottom end of the movable blade 4 falls into the limiting groove 12. At this time, the first compression spring 13 plays the role of pushing the movable blade 4 back to the limiting groove 12, and there is no need to additionally set a locking assembly on the movable blade 4 to lock and limit the movable blade 4 with the outer wall of the installation cavity after it is retracted. Therefore, the adjustment is more convenient and the operation of changing the cutting blade density is more efficient.

[0041] Optionally, a plurality of mounting grooves 8 are arranged between the fixed blades 3, and the mounting grooves 8 are equidistantly arranged. Accordingly, the ejection platforms 11 on the adjusting column 10 are arranged with different lengths, and the ejection platforms 11 are used to eject the movable blades 4 between the fixed blades 3 in sequence, thereby achieving a wider range of strip width adjustment effect.

[0042] In another embodiment, the movable blades 4 are arranged in an annular array in the mounting groove 8, and a limit baffle 14 is provided on each movable blade 4. A second compression spring is provided between the limit baffle 14 and the outer wall of the mounting cavity, and the second compression spring is used to provide an elastic force to push the movable blades 4 radially inward.

[0043] It can be understood that the second compression spring is arranged outside the knife seat 2. Although the shielding and protection are slightly poor, it is convenient to install and replace.

[0044] Preferably, the movable blades 4 are arranged in an annular array in the mounting groove 8, and partitions are arranged in the annular array in the mounting groove 8. The partitions are used to isolate adjacent movable blades 4, and the partitions are also used to guide and limit the movable blades 4 in the radial direction.

[0045] It is understandable that the partitions provided on both sides of the movable blades 4 can not only isolate the movable blades 4, but also guide and limit the movable blades 4, thereby ensuring the safety and smoothness of the movement of the movable blades 4.

[0046] Preferably, please refer to Figure 1 As shown, the driving mechanism includes a motor 6, and the motor 6 is mounted on the mounting bracket 1 through a motor mounting bracket.

[0047] It is understandable that the motor 6 can drive the knife seat 2 to rotate to achieve the cutting and slitting operation. Specifically, the motor 6 can be connected to the knife seat 2 through a pulley assembly, or can be connected to a preset rotating shaft on the knife seat 2 through the output shaft of the motor 6, both of which can directly drive the knife seat 2 to rotate, and the structure is simple and the installation space is small.

[0048] Preferably, please refer to Figure 1 As shown, a support roller 9 is provided below the knife seat 2. The support roller 9 is mounted on the mounting bracket 1. A plurality of support rings are arranged at intervals along the axial direction on the outer wall of the support roller 9. The support roller 9 is used to support the steel strip to be cut.

[0049] It can be understood that the support rings arranged on the support roller 9 can support the steel strip 2 to be stripped, and the intervals between the support rings can avoid the fixed blade 3 or the movable blade 4, thereby ensuring smooth cutting.

[0050] A slitting machine comprises the above-mentioned cutting device.

[0051] The slitting machine of the utility model also has the above-mentioned beneficial effects, including that the width of the cut and slit steel strip can be conveniently adjusted.

[0053] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core ideas of the utility model. The above is only the preferred implementation method of the utility model. It should be pointed out that due to the limitations of textual expression and the objective existence of infinite specific structures, ordinary technicians in this technical field can make several improvements, modifications or changes without departing from the principles of the utility model, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the concept and technical solution of the utility model to other occasions without improvement, should be regarded as the protection of the utility model.
