DETAILED DESCRIPTION

[0016] The accompanying drawings are a specific embodiment of the present application. The embodiment includes a rack 1, the rack 1 is provided with an upper intermediate roller 2, an upper edge roller 3 and a lower roller 4 as working rollers, each working roller is provided with a separate power system, and the corresponding type (driving torque) of hydraulic motor reducer is selected according to the actual force condition and driving torque demand of each working roller, the driving torque of the first working roller (i.e. two on both sides of the lower roller 4) is 33% of the driving torque of the second working roller (i.e. two upper edge rollers 3), the driving torque of the first working roller (i.e. two on both sides of the lower roller 4) is 25% of the driving torque of the remaining intermediate working rollers (i.e. two upper intermediate rollers 2 and two lower rollers 4), and the size of the hydraulic motor reducer is selected according to the corresponding driving torque size.

[0017] According to the position structure and action mode of the upper intermediate roller 2, the upper edge roller 3 and the lower roller 4 of the single flatting machine, an upper intermediate roller hydraulic drive system 5, an upper edge roller hydraulic drive system 6 and a lower roller hydraulic drive system 7 are respectively arranged.

[0018] The structure principles of the upper intermediate roller hydraulic drive system 5, the upper edge roller hydraulic drive system 6 and the lower roller hydraulic drive system 7 are similar, and the upper intermediate roller hydraulic drive system 5 is taken as an example for description. The upper intermediate roller hydraulic drive system 5 includes an upper intermediate roller drive shaft head 23, an upper intermediate roller shaft head clamping plate 26, an upper intermediate roller hydraulic motor reducer 8, an upper intermediate roller torsion arm 11, an upper intermediate roller hinged shaft 12, an upper intermediate roller hinged shaft gland 60 and an upper intermediate roller fixed shaft gland 63, an upper intermediate roller hinged shaft baffle 61 and an upper intermediate roller fixed shaft baffle 64, an upper intermediate roller hinged shaft aligning bearing 59 and an upper intermediate roller fixed shaft aligning bearing 62, an upper intermediate roller swing rod 13, an upper intermediate roller fixed shaft 14, an upper intermediate roller shaft baffle 58, an upper intermediate roller cylindrical pin 24 and an upper intermediate roller screw 25.

[0019] The upper middle roller drive shaft head 23 has a positioning boss 28 at one end, which cooperates with the upper middle roller end stop 29 to realize the positioning of the upper middle roller drive shaft head 23 relative to the center of the upper middle roller 2. The upper middle roller drive shaft head 23 is provided with a plurality of pin holes and a plurality of screw holes, and is installed at one end of the upper middle roller 2 through the upper middle roller cylindrical pin 24 and the upper middle roller screw 25; the upper middle roller cylindrical pin 24 is used to bear the torque of the upper middle roller drive shaft head 23 driving the upper middle roller 2 to rotate, and the upper middle roller screw 25 is used to press the upper middle roller drive shaft head 23 tightly to the end of the upper middle roller 2. The upper middle roller drive shaft head 23 is provided with internal splines, and the other end without a positioning boss is provided with an upper middle roller drive shaft head positioning stop 30 for positioning the output spline shaft of the hydraulic motor reducer. The upper middle roller shaft head clamping plate 26 is fixed to the end face of the upper middle roller drive shaft head 23 by screws to prevent the upper middle roller cylindrical pin 24 from falling off; at the same time, the upper middle roller shaft head clamping plate 26 is embedded in the upper middle roller hydraulic motor reducer output shaft positioning clamping groove 27 to position the upper middle roller hydraulic motor reducer 8 and limit the axial displacement of the upper middle roller hydraulic motor reducer 8. The upper middle roller hydraulic motor reducer 8 is of a spline shaft output style, and the spline shaft is provided with an upper middle roller hydraulic motor reducer shaft end positioning boss 32 and an upper middle roller hydraulic motor reducer positioning cylindrical table 31, and the upper middle roller hydraulic motor reducer positioning cylindrical table 31 is provided with an upper middle roller hydraulic motor reducer output shaft positioning clamping groove 27; the upper middle roller hydraulic motor reducer shaft end positioning boss 32 cooperates with the upper middle roller internal stop 33, the upper middle roller hydraulic motor reducer positioning cylindrical table 31 cooperates with the upper middle roller drive shaft head positioning stop 30, and the upper middle roller hydraulic motor reducer output shaft positioning clamping groove 27 is used to install the upper middle roller shaft head clamping plate 26 to realize the positioning of the upper middle roller hydraulic motor reducer 8.

[0020] The one end of the upper intermediate roll torsion arm 11 is machined with the upper intermediate roll torsion arm stop 56 which installs the upper intermediate roll hydraulic motor reducer shell positioning boss 57, and there are several threaded holes which position the upper intermediate roll hydraulic motor reducer 8 circumferentially. The other end of the upper intermediate roll torsion arm 11 installs the upper intermediate roll hinged shaft 12 which is above the upper intermediate roll 2. The upper intermediate roll hinged shaft 12, the upper intermediate roll hinged shaft gland 60, the upper intermediate roll hinged shaft baffle 61 and the upper intermediate roll hinged shaft plummer block 59 hinge the one end of the upper intermediate roll swing lever 13 and the one end of the upper intermediate roll torsion arm 11 together. The application of the upper intermediate roll hinged shaft plummer block 59 enables the upper intermediate roll swing lever 13 to produce a swing angle relative to the upper intermediate roll torsion arm 11. The other end of the upper intermediate roll swing lever 13 is connected by the upper intermediate roll fixed shaft gland 63, the upper intermediate roll fixed shaft baffle 64, the upper intermediate roll fixed shaft plummer block 62 and the upper intermediate roll fixed shaft 14. The upper intermediate roll fixed shaft 14 is fixedly installed on the rack 1. The application of the upper intermediate roll fixed shaft plummer block 62 enables the upper intermediate roll swing lever 13 to produce a swing angle relative to the upper intermediate roll fixed shaft 14. In this way, when the upper intermediate roll 2 is deflection adjusted, the position of the upper intermediate roll hydraulic motor reducer 8 swings following the deflection of the upper intermediate roll 2. The upper intermediate roll torsion arm 11 and the upper intermediate roll swing lever 13 can follow the swing, avoiding mechanical interference. The deflection adjustment range of the upper intermediate roll 2 is small. The swing range of the upper intermediate roll hydraulic motor reducer 8, the upper intermediate roll torsion arm 11 and the upper intermediate roll swing lever 13 are all small, which can meet the use requirements.

[0021] The structure of the upper intermediate roll hydraulic drive system 5 adapts to the feature that the height position of the upper intermediate roll 2 is adjustable. The axis of the upper intermediate roll 2, the upper intermediate roll hinged shaft 12 and the upper intermediate roll fixed shaft 14 form a triangular stable structure. The upper intermediate roll torsion arm 11 and the upper intermediate roll swing lever 13 enable the upper intermediate roll fixed shaft 14 to bear the reverse torque of the upper intermediate roll hydraulic motor reducer 8 driving the upper intermediate roll 2 to rotate.

[0022] The upper edge roll hydraulic drive system 6 includes the upper edge roll drive shaft head 34, the upper edge roll shaft head clamping plate 37, the upper edge roll hydraulic motor reducer 9, the upper edge roll torsion arm 15, the guide sliding block 18 and the guide rail plate 17. The structure principle of the upper edge roll drive shaft head 34, the upper edge roll shaft head clamping plate 37 and the upper edge roll hydraulic motor reducer 9 is the same as that of the upper intermediate roll hydraulic drive system 5. The upper edge roll torsion arm 15 is machined with a vertical direction guide sliding groove 16. The guide sliding block 18 is vertically fixed on the rack 1. The guide rail plate 17 is installed on both sides of the guide sliding block 18. The guide rail plate 17 is made of copper alloy wear-resistant material. When the height position of the upper edge roll 3 is adjusted, the guide sliding groove 16 on the upper edge roll torsion arm 15 is adjusted by the vertical direction lifting of the guide sliding block 18. The guide sliding block 18 bears the reverse torque of the upper edge roll hydraulic motor reducer 9 driving the upper edge roll 3 to rotate through the upper edge roll torsion arm 15. Through the swing of the upper edge roll torsion arm 15, the mechanical interference caused by the deflection deformation of the upper edge roll 3 can be eliminated.

[0023] The lower roller 4 is fixed in position, and the lower roller torsion arm 19 and the lower roller swing rod 21 of the lower roller hydraulic drive system 7 are designed to eliminate the influence of the assembly error (center height position variation) of the lower roller 4 on the lower roller hydraulic drive system 7.

[0024] The driving torque of the import and export first working rollers (i.e. the two on the sides of the lower roller 4) is 33% of the driving torque of the import and export second working rollers (i.e. the two upper side rollers 3), and the driving torque of the import and export first working rollers (i.e. the two on the sides of the lower roller 4) is 25% of the driving torque of the remaining intermediate working rollers (i.e. the upper intermediate rollers 2 and the two middle lower rollers 4), so that the driving torque of the import and export first working rollers is at least one specification smaller than the driving torque of the import and export second working rollers and two specifications smaller than the driving torque of the remaining intermediate working rollers, thereby reducing the manufacturing cost of the equipment.
