Description

Technical Field

[0001] The invention relates to a winding device used in a cold rolling production line of the metallurgical industry and capable of realizing two winding modes, upper and lower winding modes, and belongs to the technical field of metallurgical equipment. Background Art

[0002] The process flow of cold rolling production is pickling-rolling mill-annealing-leveling-stretching-tinning. At present, there is basically only one winding method in the straightening process. Generally, the equipment realizes the turning over of the strip by unwinding and winding. Since the general materials will no longer be reworked after tinning, the straightening process has the important function of checking the quality of the plate surface and reworking the materials. When judging the quality of tinned coils, it is generally required that the quality of the upper plate surface is significantly better than that of the lower plate surface, so minor defects should be placed on the lower plate surface. In normal production, defects such as oil spots and roller scratches on the plate surface caused by oil dripping from the leveling machine roll or foreign objects falling generally appear on the strip. The straightening process realizes the turning over of the strip by unwinding and winding, and turns the defects to the lower plate surface to improve the quality of the upper plate surface and reduce quality risks. However, due to foreign matter such as cracked carbon black in the strip, as well as factors such as the production environment, production process and operating techniques, sometimes there will be defects such as pressure marks, color differences, scratches, roller scratches, etc. on the lower plate surface that obviously affect the quality of the plate surface, while the upper plate surface is free of defects. At this time, if the upper unwinding and lower winding methods are still used, the quality of the upper plate surface cannot meet the requirements. Generally, in this case, the strip can be turned over through secondary production by straightening so that the quality of the upper plate surface can meet customer requirements. According to incomplete statistics, the proportion of secondary production of straightening caused by the above-mentioned quality defects is between 5% and 15%. Such a high frequency of secondary production will seriously affect the normal production order and will also greatly increase production costs. Summary of the invention

[0018] See attached Figure 2 , Attachment Figure 3 and attached Figure 4The transmission mechanism includes a magnetic belt 1, an active fixed roller 2, a lower translation roller 3, a lower transverse gear plate 4, an upper gear 5, a lower gear 6, an upper translation roller 7, a driven fixed roller 8, an angle adjustment cylinder 9, a transmission box 10, a steering roller 11, a lifting cylinder 12, an upper transverse gear plate 20, an upper slide rail 24, a lower slide rail 25, a lifting frame 26 and a frame 27.

An upper slide rail 24 and a lower slide rail 25 higher than the driven fixed roller 8 are provided on the conveying box 10, and the upper slide rail 24 is located above the lower slide rail 25. The upper transverse gear plate 20 and the lower transverse gear plate 4 are slidably installed on the upper slide rail 24 and the lower slide rail 25 respectively, and can move along the upper slide rail 24 and the lower slide rail 25. The upper gear 5 and the lower gear 6 are installed on the conveying box 10 and the two are meshed with each other. The upper gear 5 is meshed with the upper transverse gear plate 20, and the lower gear 6 is meshed with the lower transverse gear plate 4. The upper translation roller 7 is installed at the end of the upper transverse gear plate 20 close to the winding mechanism, and the lower translation roller 3 is installed at the end of the lower transverse gear plate 4 away from the winding mechanism. The magnetic belt 1 is wrapped around the active fixed roller 2, the upper translation roller 7, the lower translation roller 3 and the driven fixed roller 8.

[0019] See attached Figure 5 and attached Figure 6 In the case of downward winding, the strip 19 passes through the top of the steering roller 11, and in the case of upward winding, the strip 19 passes through the bottom of the steering roller 11. In order to ensure the stability of the horizontal winding device and the product quality, the height of the strip 19 in the two winding methods remains unchanged, otherwise the strip is easily scratched when the winding method is changed. The present invention adjusts the height of the steering roller 11 by the lifting cylinder 12, so that the distance that the steering roller 11 moves upward or downward is exactly the diameter of the steering roller 11, so that the height of the strip remains unchanged when turning upward or downward.

[0020] The magnetic belt 1 is used to support and convey the steel strip 19 so that the steel strip 19 can be smoothly wound around the reel 16 from below or above after being turned by the turning roller 11. The present invention adjusts the height of the conveying box 10 by the lifting cylinder 12, and then adjusts the height of the magnetic belt 1, so that it can support and convey the steel strip 19 to the top or bottom of the reel 16.

[0021] See attached Figure 3 -Attached Figure 6The upper translation roller 7 in the transmission mechanism can extend or retract toward the reel 16 under the control of the lower gear 6, the upper gear 5, the lower transverse gear plate 4 and the upper transverse gear plate 20, thereby realizing the extension or retraction of the magnetic belt 1, and the strip steel 19 can be smoothly wound onto the reel 16 by adjusting the supporting position.

[0022] The active fixed roller 2 is connected to the driving motor to drive the belt to run. The active fixed roller 2, the lower translation roller 3, the upper translation roller 7 and the driven fixed roller 8 are all provided with transverse lines and side baffles to ensure that the belt does not deviate when the conveying mechanism moves.

[0023] The upper gear 5 is directly meshed with the upper transverse gear plate 20, and the lower gear 6 is directly meshed with the lower transverse gear plate 4. The lower gear 6 is in a fixed position and is connected to the external motor of the conveying box 10. The diameter ratio of the upper gear 5 and the lower gear 6 is 2:1, that is, the upper gear 5 rotates one circle and the lower gear 6 rotates 2 circles. The upper gear 5 drives the upper transverse gear plate 20 to move, and the lower gear 6 drives the lower transverse gear plate 4 to move. The upper transverse gear plate 20 and the lower transverse gear plate 4 move in the same direction and distance. The lower gear 6 adopts a smaller diameter to reduce the driving force of the motor.

[0024] Driven by an external motor, the lower gear 6 drives the upper gear 5 to rotate, and at the same time drives the lower transverse gear plate 4 and the upper transverse gear plate 20 to move along the upper slide rail 24 and the lower slide rail 25 respectively, so that the lower translation roller 3 and the upper translation roller 7 move in the same direction at the same speed, and the magnetic belt 1 extends or contracts accordingly. Figure 3 As shown, when the motor drives the lower gear 6 to rotate clockwise, it drives the upper gear 5 to rotate counterclockwise, the upper gear 5 drives the upper transverse gear plate 20 to move leftward, and the lower gear 6 drives the lower transverse gear plate 4 to move leftward, so that the magnetic belt 1 is extended. Figure 4 As shown, when the motor drives the lower gear 6 to rotate counterclockwise, it drives the upper gear 5 to rotate clockwise, the upper gear 5 drives the upper transverse gear plate 20 to move rightward, and the lower gear 6 drives the lower transverse gear plate 4 to move rightward, so that the magnetic belt 1 contracts.

[0025] See attached Figure 1 , Attachment Figure 5 and attached Figure 6 With the assistance of the upper oil cylinder 13 or 17, the strip can be coiled from the upper side or from the lower side.

[0026] See attached Figure 5 and attached Figure 6 The lower swing arm 23 is driven away from the reel 16 by the contraction of the lower cylinder 17, and the upper swing arm 22 is driven to contract and move closer to the reel 16 by the extension of the upper cylinder 13. At the same time, the tensioning cylinder 15 retracts and the auxiliary winding belt 21 is tightened, so that the strip enters the winding mechanism from below and is wound around the reel 16 with the help of the auxiliary winding belt 21, thereby realizing the lower winding function.

[0027] Similarly, the upper swing arm 22 is driven away from the reel 16 by the contraction of the upper cylinder 13, and the lower swing arm 23 is driven to contract and move closer to the reel 16 by the extension of the lower cylinder 17. At the same time, the tensioning cylinder 15 retracts and the auxiliary winding belt 21 is tightened, so that the strip enters the winding mechanism from above and is wound around the reel 16 with the help of the auxiliary winding belt 21, thereby realizing the upper winding function.

[0028] After winding is completed, the upper cylinder 13 and the lower cylinder 17 retract so that the upper swing arm 22 and the lower swing arm 23 are both away from the reel 16, and the tensioning cylinder 15 extends so that the auxiliary winding belt 21 is in a relaxed state, and the transverse cylinder 18 retracts, so that the entire winding mechanism runs backward, and the equipment operates normally.

[0029] The beneficial effects of the present invention are as follows: the present invention realizes the upper coiling and lower coiling functions on the same tensioning and leveling machine, which can greatly reduce the amount of rework, improve production efficiency, and reduce production costs while ensuring product quality.
