Conveyor belt for fixed-length follow-up flying shear and fixed-length follow-up flying shear system

Abstract

The present invention relates to a conveying belt machine for a fixed-length follow-up flying shear and a fixed-length follow-up flying shear system. The conveying belt machine for the fixed-length follow-up flying shear includes a frame, a belt, and belt rollers. The frame includes a sliding bracket that can reciprocally slide in the horizontal direction. The belt rollers include movable rollers installed on the sliding bracket. When the sliding bracket slides, the movable rollers follow in the horizontal direction so that the horizontal conveying surface of the belt extends or contracts, thereby matching the reciprocating movement of the flying shear. No matter where the flying shear shears the steel strip, the present invention can ensure that the conveying belt machine can be closely connected downstream of the flying shear, thereby more stably transporting the sheared steel strip.

Description

Technical Field

[0001] The present invention relates to the field of metallurgical rolling machinery, and particularly to an improvement of a conveying belt conveyor for a fixed-length following flying shear. Background Art

[0002] The fixed-length following flying shear system is widely used in continuous strip steel processing lines such as silicon steel, carbon steel, and stainless steel. In the existing fixed-length following flying shear system, the position of the belt of the conveyor is fixed, while the flying shear has a reciprocating movement stroke, which results in the distance between the flying shear and the belt of the conveyor being always uncertain. This not only is not conducive to the cut strip steel falling into the conveyor for conveying, but also affects the fixed length of the strip steel, causing a certain manufacturing error. Summary of the Invention

[0003] Therefore, in view of the above problems, the present invention proposes a conveying belt conveyor for a fixed-length following flying shear with an optimized structure, and based on this conveying belt conveyor, a fixed-length following flying shear system is also proposed.

[0004] The present invention is implemented by adopting the following technical solutions:

[0005] The present invention proposes a conveying belt conveyor for a fixed-length following flying shear, which is used for conveying the strip steel cut by the flying shear, and includes a frame, a belt, and belt rollers. The frame includes a sliding bracket that can reciprocally slide in the horizontal direction. The belt rollers include movable rollers installed on the sliding bracket. When the sliding bracket slides, the movable rollers follow in the horizontal direction so that the horizontal conveying surface of the belt extends or contracts, thereby matching the reciprocating movement of the flying shear.

[0006] Preferably, it further includes a first idler group and a second idler group. Both the first idler group and the second idler group are composed of several horizontally arranged idlers. The first idler group and the second idler group are arranged below the belt to support the horizontal conveying surface of the belt. The axes of the idlers in the first idler group are constantly stationary. The second idler group is installed on the sliding bracket and slides following the sliding of the sliding bracket. The first idler group and the second idler group are arranged at the same height and are offset from each other.

[0007] Preferably, the length span of the first idler group and the second idler group in the horizontal direction satisfies that in the sliding stroke of the sliding bracket that extends the horizontal conveying surface, the downstream end of the second idler group is always within the length span of the first idler group.

[0008] Preferably, there are two groups of the second idler group that move synchronously. The first idler group is arranged in the middle, and the two groups of the second idler group are respectively arranged on both sides of the first idler group in the axial direction.

[0009] Among them, preferably, it further includes a third idler group, which is composed of several horizontally arranged idlers. The third idler group is installed on the sliding bracket and is upstream of the movable roller.

[0010] Among them, preferably, the third idler group and the movable roller are driven by a chain to achieve synchronous movement.

[0011] Among them, preferably, it further includes a displacement driving device. The belt roller further includes a tensioning roller. The displacement driving device is used to drive the tensioning roller to reciprocate horizontally, so that when the sliding bracket slides, the sliding of the movable roller is compensated by the sliding of the tensioning roller, thereby achieving the effect of tensioning the belt.

[0012] Among them, preferably, the displacement driving device is a linear driving cylinder.

[0013] Based on the above-mentioned conveying belt machine for a fixed-length following flying shear, the present invention also proposes a fixed-length following flying shear system, which includes pinch rolls for conveying strip steel, measuring rolls for measuring the conveying length of strip steel, a flying shear for shearing strip steel, and a conveyor for conveying the sheared strip steel. The conveyor is the above-mentioned conveying belt machine for a fixed-length following flying shear.

[0014] Among them, preferably, the flying shear is fixedly connected to the sliding bracket to drive the sliding of the sliding bracket through the reciprocating movement of the flying shear.

[0015] The present invention has the following beneficial effects: By arranging a sliding bracket on the frame of the present invention, when the movable roller installed on the sliding bracket slides, the horizontal conveying surface of the belt can be extended or contracted, so that the horizontal conveying surface of the belt can match the reciprocating movement of the flying shear. No matter where the flying shear shears the strip steel, it can ensure that the conveying belt machine can be closely connected downstream of the flying shear, thereby transporting the sheared strip steel more stably.

[0018] To further illustrate the embodiments, the present invention provides accompanying drawings. These drawings are a part of the disclosure of the present invention, mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementation manners and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation manners.

[0020] Embodiment 1:

[0021] Refer to Figure 1-2 As shown, as a preferred embodiment of the present invention, a conveying belt conveyor for a fixed-length following flying shear is provided for conveying the strip steel sheared by the flying shear. The conveying belt conveyor includes a frame 1, a belt 3 and belt rollers. The belt rollers are composed of several rollers rotatably arranged on the frame 1, including a driving roller 2 driven by a motor. The belt 3 is wound around the belt rollers to form a belt conveyor. Among them, the frame 1 includes a sliding bracket 7 that can reciprocally slide in the horizontal direction. The belt rollers also include a movable roller 9 installed on the sliding bracket 7. When the sliding bracket 7 slides, the movable roller 9 follows in the horizontal direction so that the horizontal conveying surface of the belt 3 (such as Figure 1 the upper end surface of the belt 3 in the figure is the horizontal conveying surface of the belt 3) extends or contracts, so that the horizontal conveying surface of the belt 3 can match the reciprocating movement of the flying shear. No matter where the flying shear shears the strip steel, it can ensure that the conveying belt conveyor can be closely connected downstream of the flying shear, so as to more stably transport the sheared strip steel. The sliding drive of the sliding bracket 7 can be realized by any existing displacement drive means, such as a linear stepping motor, a cylinder, an oil cylinder, etc. Moreover, the movement of the sliding bracket 7 can also be automatically controlled by electrical control means, which can be easily achieved by those skilled in the art.

[0022] The belt rollers also include a tensioning roller 5. A linear displacement cylinder 4 acts on the tensioning roller 5 to drive the tensioning roller 5 to reciprocally slide in the horizontal direction. When the sliding bracket 7 and the movable roller 9 slide, the sliding of the tensioning roller 5 compensates for the sliding of the movable roller 5, so as to achieve the effect of tensioning the belt 3. The movement stroke of the tensioning roller 5 can be in the same direction as that of the movable roller 9 or in the opposite direction to that of the movable roller 9, which depends on the actual design of the winding directions of the tensioning roller 5 and the movable roller 9 with respect to the belt 3. This example is not specifically limited. The linear displacement cylinder 4 can be replaced by other displacement drive devices, such as a linear stepping motor, in other embodiments.

[0023] The rack 1 is also provided with a first idler group 6 and a second idler group 8. Both the first idler group 6 and the second idler group 8 are composed of several horizontally arranged idlers. The first idler group 6 and the second idler group 8 are arranged at the same height below the belt 3 to support the horizontal conveying surface of the belt 3. Among them, the axes of the idlers in the first idler group 6 are fixedly arranged without movement, while the second idler group 8 is installed on a sliding bracket 7 and slides along with the sliding of the sliding bracket 7. The first idler group 6 and the second idler group 8 are offset from each other. Thus, when the sliding bracket 7 slides and the horizontal conveying surface of the belt 3 extends, the first idler group 6 and the second idler group 8 are staggered to form a larger supporting surface to support the horizontal conveying surface of the belt 3. That is to say, as the horizontal conveying surface of the belt 3 extends, the supporting surfaces of the first idler group 6 and the second idler group 8 also extend accordingly, so as to ensure that the supporting effect of the idlers on the belt 3 will not be affected by the extension of the horizontal conveying surface of the belt 3, and the stability of the conveyor structure is improved.

[0024] Further preferably, in this embodiment, the length spans of the first idler group 6 and the second idler group 8 in the horizontal direction satisfy that: during the sliding stroke of the sliding bracket 7 that extends the horizontal conveying surface of the belt 3, the downstream end 81 of the second idler group 8 is always within the length span range of the first idler group 6. That is to say, no matter which sliding position the sliding bracket 7 is in, the downstream end 81 of the second idler group 8 will not break away from the length span range of the first idler group 6. Thus, the supporting surfaces of the first idler group 6 and the second idler group 8 will never separate from each other. Even when the sliding bracket 7 slides to the farthest end, the first idler group 6 and the second idler group 8 can fully support the horizontal conveying surface of the belt 3. The satisfaction of the above conditions can be achieved by reasonably adjusting the horizontal lengths of the first idler group 6 and / or the second idler group 8.

[0025] Furthermore, in this embodiment, there are two groups of the second idler group 8 that move synchronously. The first idler group 6 is arranged at the center position in the width direction of the belt 3, and the two groups of the second idler group 8 are symmetrically arranged on both sides of the first idler group 6 in the axial direction. Thus, the supporting effects of the first idler group 6 and the second idler group 8 on the belt 3 are symmetric with respect to the width center of the belt 3, and the strip steel will not deflect to one side in the width direction of the belt 3 during the transportation process.

[0026] The conveyor belt machine further includes a third idler group 11. The third idler group 11 is composed of several horizontally arranged idlers. The third idler group 11 is installed on the sliding bracket 7 and is upstream of the movable roller 9. Under the rotation of the third idler group 11, the steel plates sheared by the flying shear can be conveyed backward, further ensuring that the strip steel stably enters the conveying path of the belt 3.

[0027] In this embodiment, the third idler group 11 and the movable roller 9 are driven by a chain 10 to achieve synchronous movement, so as to ensure that the speed of the belt 3 is the same as that of the third idler group 11. Then in actual production, as long as the speed of the belt 3 is set to be the same as the feeding speed of the strip steel, it can be ensured that the speed of the third idler group 11 is the same as the feeding speed of the strip steel.

[0028] Embodiment 2:

[0029] This embodiment provides a fixed-length following flying shear system, including pinch rolls for conveying strip steel, measuring rolls for measuring the conveying length of the strip steel, a flying shear for shearing the strip steel, and a conveyor for conveying the sheared strip steel. The conveyor is the fixed-length following conveying belt conveyor of Embodiment 1 and has the same structure and equivalent technical effects.

[0030] Further preferably, in this embodiment, the sliding bracket of the flying shear and the conveying belt conveyor are fixedly connected, so that the reciprocating movement of the flying shear can drive the sliding of the sliding bracket, saving the manufacturing cost.

[0031] The fixed-length following flying shear system of this embodiment can be used for shearing continuous strip steel, including but not limited to silicon steel, carbon steel, stainless steel, etc.

[0032] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes made to the present invention in form and detail without departing from the spirit and scope of the present invention defined by the appended claims all fall within the protection scope of the present invention.
