Description

Technical Field

[0001] This utility model relates to the field of stainless steel strip slitting, and in particular to a slitting and winding mechanism for a stainless steel coil slitting machine. Background Technology

[0002] During the manufacturing process of steel pipes, a coil of stainless steel strip is first unwound. Then, the wider strip is slit into multiple thinner strips using a slitting machine. These thinner strips are then bent and welded into steel pipes. During the slitting process, the edges of the wider strip are cut off as scrap and then wound up. Currently, the freshly cut scrap is guided to the scrap take-up roller by a vertical guide roller located behind the slitting machine. However, the vertical guide roller cannot provide effective vertical support for the scrap. When the scrap's moving speed slightly exceeds the take-up speed of the scrap take-up roller, the scrap gradually moves downwards without vertical support until it detaches from the vertical guide roller, rendering the vertical guide roller ineffective.

[0003] To guide the edge material during winding and prevent it from popping out and injuring personnel, the current method involves setting two vertical guide rollers and two horizontal guide rollers on an L-shaped base, allowing the edge material to pass through the space enclosed by these four guide rollers. However, due to the small gap between the four guide rollers, each time a new roll of wide steel strip is slit, personnel must manually pass the front end of the edge material between the four guide rollers. This is not only cumbersome, but also causes personnel to be easily scratched on the arms by the edge material when catching it from the other side, even while wearing gloves, because the guide rollers obstruct the view.

[0004] In addition, during the process of winding the edge material, as the edge material is gradually wound along the length of the edge material winding roller, the strip edge material may scrape against the vertical plate of the L-shaped seat when it passes through the L-shaped seat. This not only poses a risk of edge material breakage, but also wears down the vertical plate of the L-shaped seat. Utility Model Content

[0005] The purpose of this invention is to provide a slitting and winding mechanism for a stainless steel coil slitting machine, which allows operators to quickly and safely pass the front end of the edge material through each guide roller, making operation convenient.

[0006] To achieve the above objectives, this utility model provides a slitting and winding mechanism for a stainless steel coil slitting machine, comprising a discharge guide structure, a winding guide structure, and an edge material winding roller assembly arranged sequentially along the edge material conveying direction; the winding guide structure includes an L-shaped seat, which includes an L-shaped seat body with a vertical plate and a horizontal plate, and a swing seat, wherein the horizontal plate of the L-shaped seat body and the swing seat are rotatably connected by a first rotating shaft, and a locking structure is provided between the L-shaped seat body and the swing seat; two horizontal guide rollers are rotatably connected to the vertical plate of the L-shaped seat body, and the two horizontal guide rollers are arranged side by side, and vertical guide rollers are rotatably connected to the horizontal plate of the L-shaped seat body and the swing seat respectively.

[0007] As a further improvement of this utility model, the locking structure includes a socket and a pin that are mutually inserted and mated. The socket is set on the horizontal plate of the L-shaped base body, and the pin passes through the swing base. A handle is connected to the end of the pin away from the socket.

[0008] As a further improvement of this utility model, a baffle is connected to the pin, and a return spring is provided between the baffle and the swing seat.

[0009] As a further improvement of this utility model, a sliding seat is provided below the L-shaped seat, and a guide rail is slidably connected to the sliding seat. The sliding seat and the L-shaped seat are linked by a rotation drive mechanism.

[0010] As a further improvement of this utility model, the rotation drive mechanism includes a meshing gear and a rack, the gear being rotatably connected to the sliding seat, and the gear being coaxially fixedly connected to the L-shaped seat body via a second rotating shaft.

[0011] As a further improvement of this utility model, a guide rail bracket is connected to the end of the guide rail, and a reciprocating drive device is installed on the guide rail bracket. The output end of the reciprocating drive device is connected to the sliding seat.

[0012] As a further improvement of this utility model, the discharge guiding structure includes a guide seat set on the slitting machine, and a sliding strip is slidably connected on the guide seat; the sliding strip is provided with a horizontally arranged first guide roller and a vertically arranged second guide roller, the first guide roller and the second guide roller are arranged sequentially along the conveying direction of the edge material, and the highest point of the first guide roller is located between the upper end and the lower end of the second guide roller.

[0013] Beneficial effects

[0014] Compared with the prior art, the advantages of the slitting and winding mechanism of the stainless steel coil slitting machine of this utility model are as follows:

[0015] 1. When a new roll of wide steel strip is slit, the operator unlocks the locking mechanism, allowing the swing seat to rotate at a certain angle relative to the horizontal plate of the L-shaped seat body. This causes the two vertical guide rollers to no longer be parallel to each other. At this point, the space enclosed by all the guide rollers will open on one side, allowing the edge material of the steel strip to be quickly moved between the guide rollers from that side. Then, the swing seat is reset and fixed by the locking mechanism. This structure is convenient to use.

[0016] 2. The locking structure uses a pin-and-socket combination, which is simple in structure and low in production cost. A return spring is provided between the pin's baffle and the swing seat. The return spring can be used to reset the pin, avoiding the problem of personnel forgetting to reinsert the pin into the socket.

[0017] 3. During the lateral movement of the L-shaped seat along the guide rail, the edge material of the steel strip can be wound along the length direction of the edge material winding roller through each guide roller. During the lateral movement, the L-shaped seat and the sliding seat also rotate relative to each other, which avoids the edge material from contacting the vertical plate of the L-shaped seat, prevents the vertical plate of the L-shaped seat from wearing, extends the service life, and also reduces the risk of sudden breakage of the edge material, making it safer.

[0018] 4. The edge material is supported by the first guide roller to prevent it from sliding down, and then guided horizontally outward by the second guide roller. This structure ensures that the edge material does not leave the coverage area of ​​the second guide roller, guaranteeing that the second guide roller always plays a guiding role for the edge material.

[0030] Example

[0031] The specific embodiments of this utility model are as follows: Figures 1 to 8 As shown, a slitting and winding mechanism for a stainless steel coil slitting machine includes a discharge guide structure 10, a winding guide structure, and an edge material winding roller assembly arranged sequentially along the conveying direction of the edge material 9. The edge material winding roller assembly includes an edge material winding roller 8 and a drive motor 81 that are linked together. The winding guide structure includes an L-shaped seat 1, which includes an L-shaped seat body 11 with vertical and horizontal plates, and a swing seat 12. The horizontal plate of the L-shaped seat body 11 and the swing seat 12 are rotatably connected by a first rotating shaft 13. A locking structure 4 is also provided between the L-shaped seat body 11 and the swing seat 12. Two horizontal guide rollers 2 are rotatably connected to the vertical plate of the L-shaped seat body 11, and the two horizontal guide rollers 2 are arranged side by side. Vertical guide rollers 3 are rotatably connected to the horizontal plate of the L-shaped seat body 11 and the swing seat 12, respectively.

[0032] Since the steel strip is cut into edge material 9 on both sides during slitting, the discharge guide structure 10, the winding guide structure, and the edge material winding roller assembly are arranged in two sets and symmetrically on the left and right sides of the slitting machine.

[0033] The discharge guiding structure 10 includes a guide seat 102 mounted on a sliding machine (not shown in the figure), and a sliding strip 101 slidably connected to the guide seat 102. The sliding strip 101 is equipped with a horizontally arranged first guide roller 104 and a vertically arranged second guide roller 105, which are arranged sequentially along the conveying direction of the edge material 9. The highest point of the first guide roller 104 is located between the upper and lower ends of the second guide roller 105. The sliding strip 101 passes through a guide hole in the middle of the guide seat 102, and a locking screw 103 is threaded onto the guide seat 102. The end of the locking screw 103 presses against the side wall of the sliding strip 101 to lock it in place.

[0034] The edge material 9 first passes between two horizontal guide rollers 2, and then between two vertical guide rollers 3. The swing seat 12 is located on the side of the horizontal plate of the L-shaped seat body 11 away from the vertical plate, which facilitates operation.

[0035] The locking structure 4 includes a socket 45 and a pin 41 that are mutually inserted and engaged. The socket 45 is located at one end of the horizontal plate of the L-shaped base body 11, and the pin 41 passes through the swing base 12. A handle 42 is connected to the end of the pin 41 away from the socket 45, and the handle 42 is located outside the swing base 12.

[0036] A baffle 43 is connected to the pin 41, and a return spring 44 is provided between the baffle 43 and the swing seat 12. The return spring 44 is sleeved on the outside of the pin 41.

[0037] In use, the operator holds the front end of the edge material 9 with one hand and operates the handle 42 with the other to pull the pin 41 out of the insertion hole 45. Then, the operator directly flips the swing base 12 through the handle 42, causing the vertical guide roller 3 on the swing base 12 to rotate backward by approximately 90°. The edge material 9 is then moved from the side between the two horizontal guide rollers 2 and the two vertical guide rollers 3. The swing base 12 and the vertical guide rollers 3 connected to it are then reset, and the pin 41 is released, allowing it to be reinserted into the insertion hole 45. During this process, it is not necessary to switch hands when moving the edge material 9, and the view is not obstructed, thus enhancing safety.

[0038] Below the L-shaped seat 1 is a sliding seat 5, which is slidably connected to a guide rail 7. The sliding seat 5 and the L-shaped seat 1 are linked by a rotation drive mechanism 6. The guide rail 7 and the edge material take-up roller 8 are parallel to each other.

[0039] The rotation drive mechanism 6 includes a meshing gear 61 and a rack 63. The gear 61 is rotatably connected to the sliding seat 5, and the gear 61 is coaxially fixedly connected to the L-shaped seat body 11 via a second rotating shaft 62. The rack 63 is parallel to the guide rail 7, and both ends of the rack 63 are fixedly connected to the guide rail bracket 71.

[0040] Guide rail 7 has guide rail brackets 71 connected to both ends. A reciprocating drive device 72 is mounted on one of the guide rail brackets 71, and the output end of the reciprocating drive device 72 is connected to the sliding seat 5. In this embodiment, the reciprocating drive device 72 is a hydraulic cylinder. The reciprocating drive device 72 drives the sliding seat 5 to slide along the guide rail 7.

[0041] During the lateral movement of the L-shaped seat 1 along the guide rail 7, the edge material 9 of the steel strip can be wound along the length direction of the edge material winding roller 8 by the transverse guide roller 2 and the vertical guide roller 3. During the lateral movement, due to the meshing of the gear 61 and the rack 63, the L-shaped seat 1 and the sliding seat 5 will also rotate relative to each other around the second rotating shaft 62, preventing the edge material 9 from contacting the vertical plate of the L-shaped seat 1. Figure 2As shown, this design prevents wear on the vertical plate of the L-shaped seat 1, extending its service life, and also reduces the risk of sudden breakage of the edge material 9, resulting in higher safety.

[0042] The present invention has been described above in conjunction with the preferred embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations made in accordance with the essence of the present invention.
