Description

Technical Field

[0001] This utility model relates to the field of steel plate slitting technology, and in particular to a tension roller device for a steel plate slitting machine. Background Technology

[0002] A steel plate slitting machine is a specialized piece of equipment that uses mechanical shearing to continuously cut wide steel plate coils into multiple narrow strips. After the steel plate coils are cut into narrow strips, each narrow strip needs to be wound up. By using tension rollers, a stable and adjustable forward tension can be provided for each narrow strip, so that the narrow strips can be wound up neatly and tightly.

[0003] However, it is worth considering that after the steel sheet coil is slit, multiple narrow strips will pass through the tension rollers at the same time for tension adjustment. If there are slight differences in the parallelism of the tension rollers and the condition of the roller surface, it may cause the tension on each narrow strip to be inconsistent. The strip with greater force will be tightened, and the strip with excessive tension may even be pulled apart.

[0004] Therefore, in order to solve the above problems, a more suitable facility that meets the needs of users is needed. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a tension roller device for a steel plate slitting machine to solve the problem of inconsistent tension on the various narrow strips, where the strip with greater force is wound tightly, and the strip with excessive tension may even break.

[0006] Based on the above objectives, this utility model provides a tension roller device for a steel plate slitting machine, including a frame, a guiding mechanism for guiding the narrow strip steel after cutting and slitting, and two sets of tension adjustment components for adjusting the tension of the narrow strip steel.

[0007] Each tension adjustment assembly includes several rotating shafts arranged in sequence. Tension rollers for supporting narrow strip steel are fixedly sleeved on the outside of the rotating shafts. Two sets of tension adjustment assemblies are arranged vertically in sequence. A limiting unit for limiting the vertical position of the rotating shafts is provided on the frame. A rotating frame is rotatably sleeved on the outside of the rotating shafts. A movable seat is rotatably connected to the end of the rotating frame away from the rotating shafts. An elastic translation structure for driving the movable seat to move horizontally is provided on the frame.

[0008] Preferably, the elastic translation structure includes several movable frames disposed above the frame, several first hydraulic telescopic rods are fixedly connected to the frame, and the telescopic ends of the first hydraulic telescopic rods are fixedly connected to the corresponding movable frames, and elastic elements adapted to the movable seats are installed on the movable frames.

[0009] Preferably, the elastic element includes a movable plate disposed within the movable frame, the movable plate and the movable seat are connected by a plurality of guide posts, a compression spring is sleeved on the outside of the guide posts, and the two ends of the compression spring are fixedly connected to the outer wall of the movable seat and the movable frame, respectively.

[0010] Preferably, contact switches are provided on both sides of the movable plate, and the contact switches are fixedly connected to the inner wall of the movable frame.

[0011] Preferably, a plurality of guide plates are fixedly connected to the frame, and the guide plates pass through the corresponding movable seat, movable frame and movable plate respectively.

[0012] Preferably, the limiting unit includes side plates respectively disposed on both sides of the rotating frame, the side plates and the frame are fixedly connected, the side plates are provided with rectangular holes adapted to the rotating shaft, and the two ends of the rotating shaft are respectively located in the corresponding rectangular holes.

[0013] Preferably, the guiding mechanism includes two first support rollers rotatably mounted on the frame, the two first support rollers being arranged vertically in sequence, a second support roller being provided above the frame, the two ends of the second support roller being rotatably connected to support parts, and the support parts being fixedly connected to the frame, two sets of tension adjustment components being located on the side of the second support roller facing the first support roller, a lifting roller being provided above the second support roller, the two ends of the lifting roller being rotatably connected to lifting seats, a second hydraulic telescopic rod being fixedly connected to the support parts, and the telescopic end of the second hydraulic telescopic rod being fixedly connected to the lifting seat.

[0014] The beneficial effects of this utility model are as follows: The narrow strip steel cut into strips is guided by a guiding mechanism, and the corresponding movable seat is moved horizontally by an elastic translation structure. The movable seat is driven by a rotating frame to move the rotating shaft and tension roller vertically. The tension roller applies pressure to the corresponding narrow strip steel, thereby changing the tension of the narrow strip steel. By independently adjusting the tension roller, the operator can control the tension of each narrow strip steel and reduce the tension of the narrow strip steel with smaller widths individually. While ensuring that the narrow strip steel is tightly wound, it can protect the fragile narrow strip steel, thereby significantly reducing the probability of the entire line breaking and stopping, and improving production continuity.

[0026] This specification provides one or more embodiments of a tension roller device for a steel plate slitting machine, such as... Figure 1 , Figure 2 and Figure 4As shown, it includes a frame 1, a guide mechanism for guiding the narrow strip steel 30 after cutting and slitting, and two sets of tension adjustment components for adjusting the tension of the narrow strip steel 30.

[0027] Each tension adjustment assembly includes several rotating shafts 2 arranged in sequence. Tension rollers 3 for supporting narrow strip steel 30 are fixedly sleeved on the outside of each rotating shaft 2. Two sets of tension adjustment assemblies are arranged vertically in sequence. A limiting unit for limiting the vertical position of the rotating shafts 2 is provided on the frame 1. A rotating frame 4 is rotatably sleeved on the outside of each rotating shaft 2. A movable seat 5 is rotatably connected to the end of the rotating frame 4 away from the rotating shaft 2. An elastic translation structure is provided on the frame 1 for driving the movable seat 5 to move horizontally. The narrow strip steel 30 being cut and slit is guided by a guiding mechanism and by elastic... The translation structure pushes the corresponding movable seat 5 to move horizontally. The movable seat 5 drives the rotating shaft 2 and tension roller 3 to move vertically through the rotating frame 4. The tension roller 3 applies pressure to the corresponding narrow strip steel 30, thereby changing the tension of the narrow strip steel 30. By independently adjusting the tension roller 3, the operator can control the tension of each narrow strip steel 30 and reduce the tension of the narrow strip steel 30 with smaller widths individually. While ensuring that the narrow strip steel 30 is tightly wound, it can protect the fragile narrow strip steel 30, thereby significantly reducing the probability of the entire line breaking and stopping, and improving production continuity.

[0028] In embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, the elastic translation structure includes several movable frames 6 disposed above the frame 1. Several first hydraulic telescopic rods 11 are fixedly connected to the frame 1, and the telescopic ends of the first hydraulic telescopic rods 11 are fixedly connected to the corresponding movable frames 6. Elastic elements adapted to the movable seats 5 are installed on the movable frames 6. The elastic elements include movable plates 7 disposed inside the movable frames 6. The movable plates 7 and the movable seats 5 are connected by several guide posts 8. Compression springs 9 are sleeved on the outside of the guide posts 8, and the two ends of the compression springs 9 are fixedly connected to the outer walls of the movable seats 5 and the movable frames 6, respectively. Contact switches 10 are respectively provided on both sides of the movable plates 7, and the contact switches 10 and the movable frames 6 are connected to each other. The inner wall of the frame 6 is fixedly connected, and several guide plates 12 are fixedly connected to the frame 1. The guide plates 12 pass through the corresponding movable seats 5, movable frames 6 and movable plates 7 respectively. The limiting unit includes side plates 13 respectively set on both sides of the rotating frame 4. The side plates 13 are fixedly connected to the frame 1. The side plates 13 are provided with rectangular holes 14 adapted to the rotating shaft 2, and the two ends of the rotating shaft 2 are respectively located in the corresponding rectangular holes 14. The movable frame 6 is driven to move by the first hydraulic telescopic rod 11. The movable frame 6 pushes the movable seat 5 to move horizontally by the compression spring 9. The movable seat 5 pushes the rotating shaft 2 and tension roller 3 to move by the rotating frame 4. The rotating shaft 2 and tension roller 3 are vertically oriented. The tension roller 3 supports the narrow strip 30, and the movable frame 6 is continuously moved by the first hydraulic telescopic rod 11, changing the distance between the movable frame 6 and the movable seat 5, thereby controlling the length of the compression spring 9, and thus controlling the pressure applied by the tension roller 3 to the narrow strip 30. The movable frame 6 slides relative to the guide post 8 and the movable plate 7. As the narrow strip 30 continues to wind up, when the tension of the narrow strip 30 changes, the narrow strip 30 pushes the tension roller 3 and the rotating shaft 2 to move. The end of the rotating shaft 2 slides within the rectangular hole 14, and the rotating shaft 2 drives the movable seat 5 to translate via the rotating frame 4. The guide post 8 drives the movable plate 7 to slide within the movable frame 6. When the movable plate 7 contacts one of the corresponding contact switches 10, it indicates that the tension of the narrow strip steel 30 exceeds the preset range. The first hydraulic telescopic rod 11 drives the movable frame 6 to move horizontally, changing the distance between the movable seat 5 and the movable frame 6 again, so that the movable plate 7 no longer contacts the contact switch 10. This ensures that the tension of the narrow strip steel 30 is always within the preset range. The guide plate 12 passes through the movable seat 5, the movable frame 6, and the movable plate 7. The design of the guide plate 12 ensures that the movable seat 5, the movable frame 6, and the movable plate 7 move smoothly in the horizontal direction.

[0029] In embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 3As shown, the guiding mechanism includes two first support rollers 15 rotatably mounted on the frame 1. The two first support rollers 15 are arranged vertically in sequence. A second support roller 16 is provided above the frame 1. Support parts 20 are rotatably connected to both ends of the second support roller 16, and the support parts 20 are fixedly connected to the frame 1. Two sets of tension adjustment components are located on the side of the second support roller 16 facing the first support roller 15. A lifting roller 17 is provided above the second support roller 16. Lifting seats 19 are rotatably connected to both ends of the lifting roller 17. A second hydraulic telescopic rod 18 is fixedly connected to the support part 20, and the telescopic end of the second hydraulic telescopic rod 18 is fixedly connected to the lifting seat 19. Several narrow strips 30, after being cut and slit, pass between the second support roller 16 and the lifting roller 17. Then, the lifting seat 19 and the lifting roller 17 are driven to move down by the second hydraulic telescopic rod 18 so that the gap between the second support roller 16 and the lifting roller 17 is consistent with the thickness of the narrow strip 30. The narrow strip 30 guided by the second support roller 16 and the lifting roller 17 passes through the first support roller 15. The first support roller 15 guides the narrow strip 30 to the winding station. Two adjacent narrow strips 30 are guided by different first support rollers 15, and two adjacent narrow strips 30 are supported by tension rollers 3 on different tension adjustment components.
