Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of metallurgical rolling machinery, and specifically relates to a belt coiler for a rotary coiler. Background Art
[0002] To achieve continuous production of cold-rolled strip steel, generally two decoilers are adopted at the inlet section of the production line, and the tail of the strip and the head of the next coil are welded by a welding machine to realize continuous rolling; two coilers are also correspondingly configured at the outlet section. With the continuous progress of technology, the rotary double-drum coiler has emerged. It has two drum shafts that can rotate alternately. When one side is in the coiling operation, the other side is in the standby state. Compared with the traditional coiler, this coiler has the characteristics of compact structure and small installation space, and is suitable for high-altitude operations.
[0003] Since the drum is generally a multi-segment seamless drum, a belt coiler is usually required to be used in cooperation; however, after the coiling belt is used for a period of time, it will become fatigued and loose, resulting in the strip steel being prone to deviation and slipping during coiling; at this time, it is often necessary to adjust the belt tension and the wrap angle. The traditional solution usually installs eccentric sleeves at both ends of the upper and lower holding rollers. By adjusting the eccentricity of the two ends of the eccentric sleeves, the tightness of the belt is adjusted, and at the same time, the parallelism between the holding rollers and the drum is also changed in this way to improve the deviation correction function of the strip steel coiling; however, the adjustment amount of the eccentric sleeve is limited, the operation is relatively cumbersome, and in addition, the double-drum coiler is installed at a relatively high position, with a narrow space, a lot of equipment cross-operation, and a complex environment, making it difficult for manual adjustment and difficult to control the accuracy.
[0004] Therefore, we believe that it is necessary to develop a belt coiler device with a large belt tension adjustment range and simple operation. Content of the Utility Model

[0023] Embodiment
[0024] At present, when adjusting the wrap angles and tensions of the upper holding roller 5 and the lower holding roller 6 of the coiler's coil assisting device, in the method of installing an eccentric sleeve, since the eccentric sleeve structure has limited adjustment amount when adjusting the eccentricity, and the adjustment is rather cumbersome. Moreover, the double-drum coiler is installed at a relatively high position with narrow space, a lot of equipment cross-operation, and a complex environment. The complex adjustment operation makes it difficult for manual adjustment, and the accuracy is hard to control. To solve this problem, we have designed a belt coil assisting device for a coiler that is convenient to operate. The specific solution is as follows:
[0025] As Figures 1-3 shown, a belt coil assisting device for a turntable coiler disclosed in this embodiment includes a frame 1 and a coiling belt 11. Among them, the frame 1 is the load-bearing structure of the entire coil assisting device. Two sides of the bottom of the frame 1 are rotatably installed with idler rollers 18, which play a role in threading the coiling belt 11. Two sides of the top of the frame 1 are rotatably installed with connecting shafts 21 through semi-bearing seats 20. Both ends of the two connecting shafts 21 extend to the outside of the frame 1. Upper swing arms 2 and upper holding arms 3 are fixed at both ends of the connecting shaft 21 located on the front side of the frame 1, and lower swing arms 9 and lower holding arms 7 are fixed at both ends of the connecting shaft 21 located on the rear side of the frame 1. A space for surrounding the reel 12 is formed between the upper holding arm 3 and the lower holding arm 7. The upper swing arm 2 and the lower swing arm 9 are located outside the frame 1, and the upper holding arm 3 and the lower holding arm 7 are located inside the frame 1. To improve the stability of the overall structure of the coil assisting device, reinforcing ribs are provided between the upper holding arms 3 on both sides of the frame 1 and between the lower holding arms 7.
[0026] The middle position at the top of the upper holding arm 3 is rotatably installed with an upper holding belt roller 4 through a pressing plate A13, and the front end of the upper holding arm 3 is installed with an upper holding roller 5 through a pressing plate B14. Similarly, a lower holding roller 6 is installed at the top end of the lower holding arm 7 through a pressing plate B14; the middle parts of the two connecting shafts 21 at the top of the frame 1 are rotatably installed with a transition roller 19 through bearings, and a tensioning roller 10 is also rotatably installed in the middle of the frame 1. The coiling belt 11 sequentially bypasses the idler roller 18, the tensioning roller 10, the transition roller 19, the lower holding roller 6, the upper holding roller 5, and the upper holding belt roller 4 and then forms a closed loop outside the frame 1.
[0027] A tensioning oil cylinder 8 is installed between the bottom ends of the upper swing arms 2 and the lower swing arms 9 on both sides of the frame 1. The end of the telescopic cylinder at the front end of the tensioning oil cylinder 8 is hinged to the bottom end of the upper swing arm 2 through a piston rod hinge joint 801, and the tail end of the tensioning oil cylinder 8 is hinged to the bottom end of the lower swing arm 9 through a cross hinge seat 802.
[0028] When the tensioning oil cylinder 8 works, the piston rod at the telescopic end of the tensioning oil cylinder 8 extends, causing the entire oil cylinder to expand, thereby pushing the upper swing arm 2 and the lower swing arm 9 to rotate around the connecting shaft 21 and driving the connecting shaft 21 to rotate. When the connecting shaft 21 rotates, it drives the upper holding arm 3 and the lower holding arm 7 to approach the reel 12, drives the coiling belt 11 to wrap around the reel 12, rotates with the reel 12, and winds the strip steel on the reel 12 to complete the coil assisting function.
[0029] To facilitate the adjustment of the wrap angle of the belt coiler and regulate the tension of the coiling belt 11, screw rod adjusting devices are installed at both ends of the upper holding roller 5 and the lower holding roller 6. The screw rod adjusting devices at both ends of the upper holding roller 5 and the lower holding roller 6 have the same structure. The screw rod adjusting device includes a fixed ear 15, an adjusting screw rod 17, and a nut 16. For convenient adjustment, a square shaft head is provided at the bottom end of the adjusting screw rod 17. The lower screw rod part of the adjusting screw rod 17 is threadedly connected to the fixed ear 15 and the nut 16. The upper end of the adjusting screw rod 17 in the screw rod adjusting device located at both ends of the upper holding roller 5 is bolted to the flat head part of the roller shaft at the end of the upper holding roller 5, and one side of the fixed ear 15 that is helically engaged with the lower screw rod of the adjusting screw rod 17 is fixedly welded to the upper holding arm 3.
[0030] The upper end of the adjusting screw rod 17 in the screw rod adjusting device located at both ends of the lower holding roller 6 is bolted to the flat head part of the roller shaft at the end of the lower holding roller 6, and one side of the fixed ear 15 that is helically engaged with the lower screw rod of the adjusting screw rod 17 in the screw rod adjusting device located at both ends of the lower holding roller 6 is fixedly welded to the lower holding arm 7.
[0031] When adjusting the wrap angle of the coiler and the tension of the coiling belt 11, move the shaft head to rotate the adjusting screw rod 17, so that the upper holding roller 5 or the lower holding roller moves upward or downward. After the adjustment is in place, reverse the rotation of the nut 16 on the lower screw rod of the adjusting screw rod 17 to lock the adjustment position. Thus, the adjustment of the tension and wrap angle of the coiler is completed. The entire adjustment operation is simple, and the adjustment amount is much larger than the eccentric sleeve structure design. The simple adjustment operation helps the staff to quickly and accurately complete the adjustment of the wrap angle of the coiler and the tension of the coiling belt 11 in a complex working environment.
[0032] During the use of the present utility model: the large turntable of the coiler rotates to the working position of the reel 12 according to the instruction. At this time, the piston of the tensioning oil cylinder 8 contracts, and the upper holding arm 3 and the lower holding arm 7 of the belt coiler open. After the working position of the reel 12 is fixed, the piston of the tensioning oil cylinder 8 extends, and the upper holding arm 3 and the lower holding arm 7 of the belt coiler close; according to the requirements of the cold-rolled product for the tension and wrap angle or the actual operating conditions of the equipment, the screw rod adjusting devices at both ends of the upper holding roller 5 and the lower holding roller 6 are adjusted to adjust the wrap angle of the upper holding roller 5 and the lower holding roller 6 and the tension of the coiling belt 11. After the adjustment is completed, start the coiler to run, and the strip steel runs through the strip. Under the action of the coiler, it winds around the reel 12 to complete the function of threading the belt coiler.
[0033] After the coiling is completed, the No. 1 reel 12 of the coiler exits, and the No. 2 reel 12 enters the preparation state, and so on in a cycle.
[0034] The above are only embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the scope of the claims of the present utility model.
