Description

Technical Field

[0001] This utility model relates to the technical field of non-ferrous metal strip and foil cleaning line equipment, specifically to a finishing machine that automatically adjusts the roller gap. Background Technology

[0002] The existing finishing machine used at the back end of the metal strip and foil cleaning line adjusts the gap between the upper and lower finishing rollers by replacing shims of different thicknesses between the bearing seats of the upper and lower finishing rollers. Each time the gap size is adjusted, operators must manually replace the shims, resulting in a large workload and low efficiency. Furthermore, to accommodate finishing of metal strips and foils of varying thicknesses, a large number of shims of different thicknesses are required, causing difficulties in production preparation and organization. Continuous adjustment of the gap size is also impossible, meaning the gap size often cannot be set optimally, thus affecting the final surface quality of the metal strips and foils. Additionally, whenever the upper and lower finishing rollers are worn and repaired, the outer diameter of the rollers changes, requiring recalculation or recalibration of the gap size corresponding to the original shims of different thicknesses, thus adding extra unnecessary workload. These problems severely impact the uptime and production quality of the metal strip and foil cleaning line, thereby affecting the economic benefits of the production company. Utility Model Content

See the instruction manual appendix Figure 8 , 9 The assembly process of the double wedge sliding mechanism 5.2 is as follows: The flat key is fixedly installed in the flat keyway of the lower wedge 5.2.2; the wedge surface strip 5.2.1.1.1 of the upper wedge 5.2.1 is slidably installed from the left side of the lower wedge 5.2.2 in the wedge surface guide groove 5.2.2.1.1, with the wedge surfaces of the upper wedge 5.2.1 and the lower wedge 5.2.2 abutting and slidingly connected; the upper wedge 5.2.1 and the lower wedge 5.2.2, which are slidably connected together, are installed from below the wedge support 5.2.3 on the two guide plates 5.

The adjacent end face of the locking plate 5.2.4.2 and the upper wedge block 5.2.1 abuts against the side of the upper wedge block body 5.2.1.1, locking the position of the upper wedge block 5.2.1. See the instruction manual appendix Figure 2The assembly process of the roll gap adjustment mechanism 5 is as follows: The servo drive mechanism 5.1 is fixedly mounted on a column on one side of the portal frame 1.2, with the telescopic rod 5.1.2.1 facing the rectangular hole of the portal frame 1.2; the double wedge sliding mechanism 5.2 is fixedly mounted on the lower end face of the upper bearing seat 2.2 via the wedge bracket connecting plate 5.2.3.2, at which point there is a gap between the upper horizontal surface of the upper wedge 5.2.1 and the lower end face of the upper bearing seat 2.2; the bolts of the fixing locking block 5.2.4 are loosened, releasing the upper wedge 5.2.1. Position locked, move the upper wedge block 5.2.1 to the left, so that the telescopic rod 5.1.2.1 of the electric telescopic cylinder 5.1.2 is inserted into the upper wedge block connecting groove 5.2.1.3 of the upper wedge block 5.2.1. Use the nut to initially connect the telescopic rod 5.1.2.1 to the upper wedge block 5.2.1. At this time, the nut is kept loose. Retighten the fixing bolt of the locking block 5.2.4; drive the plunger of the hydraulic plunger cylinder 4 to rise, push the lower finishing roller group 3 to rise, so that the upper end face of the lower bearing seat 3.2 is aligned with the lower wedge block 5.2.2. When the upper and lower wedges 5.2.1 and 5.2.2 are in contact with each other, they are pushed upward together (at this time, the upper and lower wedges 5.2.1 and 5.2.2 are locked, and the connecting nut between the telescopic rod 5.1.2.1 and the upper wedge 5.2.1 remains unlocked), until the upper horizontal surface of the upper wedge 5.2.1 contacts the lower end surface of the upper bearing seat 2.2. Then, the connecting nut between the telescopic rod 5.1.2.1 and the upper wedge 5.2.1 is locked, and the roll gap adjustment mechanism 5 is assembled. Subsequently, when the telescopic rod 5.1.2.1 drives the upper wedge 5.2.1 to move horizontally, the upper wedge 5.2.1 can no longer move up and down. Therefore, through the cooperation of the wedge edge strip 5.2.1.1.1 and the wedge guide groove 5.2.2.1.1, the lower wedge 5.2.2 will be driven to move up and down. The flat key of the lower wedge 5.2.2 is set in the flat key guide groove 5.2.3.1.1 of the guide plate 5.2.3.1 to prevent the lower wedge 5.2.2 from moving horizontally due to friction between it and the upper wedge 5.2.1. See the instruction manual appendix Figure 13 , 14 The smoothing roller drive assembly 6 includes a motor 6.1 and a reducer 6.2, which are connected by a transmission. One end of the reducer 6.2 extends out to a reducer output shaft 6.2.1. The smoothing roller drive assembly 6 is fixedly mounted on the drive mounting frame 1.9. The reducer output shaft 6.2.1 is connected to the upper smoothing roller shaft head 2.1.1 or the lower smoothing roller shaft head 3.1.1 by a universal joint shaft 7.

[0018] The specific method for adjusting the roll gap between finishing roll group 2 and finishing roll group 3 is as follows: See the instruction manual appendix Figure 2When it is necessary to reduce the gap between the upper polishing roll group 2 and the lower polishing roll group 3, firstly, drive the plunger of the hydraulic plunger cylinder 4 to descend, causing the lower polishing roll group 3 to descend, so that the upper end face of the lower bearing seat 3.2 disengages from the lower horizontal surface of the lower wedge block 5.2.2; loosen the fixing bolt of the locking block 5.2.4; according to the pre-calculated amount, the servo drive mechanism 5.1 drives the upper wedge block 5.2.1 to move to the left by a set distance, causing the lower wedge block 5.2.2 to move upward by a set distance, and then re-tighten the fixing bolt of the locking block 5.2.4 to lock the position of the upper wedge block 5.2.1; drive the plunger of the hydraulic plunger cylinder 4 to rise, causing the lower polishing roll group 3 to rise, until the upper end face of the lower bearing seat 3.2 re-engages with the lower horizontal surface of the lower wedge block 5.2.2, completing the adjustment to reduce the gap between the upper polishing roll group 2 and the lower polishing roll group 3; When it is necessary to increase the roll gap between the upper polishing roll group 2 and the lower polishing roll group 3, firstly, drive the plunger of the hydraulic plunger cylinder 4 to descend, causing the lower polishing roll group 3 to descend, so that the upper end face of the lower bearing seat 3.2 disengages from the lower horizontal surface of the lower wedge block 5.2.2; loosen the fixing bolt of the locking block 5.2.4; according to the pre-calculated amount, the servo drive mechanism 5.1 drives the upper wedge block 5.2.1 to move to the right by a set distance, causing the lower wedge block 5.2.2 to move downward by a set distance, and then re-tighten the fixing bolt of the locking block 5.2.4 to lock the position of the upper wedge block 5.2.1; drive the plunger of the hydraulic plunger cylinder 4 to rise, causing the lower polishing roll group 3 to rise, until the upper end face of the lower bearing seat 3.2 re-engages with the lower horizontal surface of the lower wedge block 5.2.2, completing the adjustment to increase the roll gap between the upper polishing roll group 2 and the lower polishing roll group 3.

[0019] The adjustment of the gap between the upper and lower finishing roller groups 2 and 3 can be completed automatically, except for the manual operation of loosening and tightening the fixing bolts of locking block 5.2.4. This eliminates the need for numerous shims of varying thicknesses. When the outer diameter of the upper and lower finishing rollers changes due to wear and repair, simply inputting the repaired diameter into the finishing machine's control system automatically adjusts the gap. This eliminates the need to recalculate or recalibrate the gap size corresponding to shims of different thicknesses, significantly reducing the workload of adjusting the gap and improving the economic efficiency of the production enterprise. Furthermore, this automatically adjusting finishing machine allows the gap to be continuously adjusted to any desired size, ensuring the optimal gap size and guaranteeing the final surface quality of the metal strip / foil.
