Description

Technical Field

[0001] The utility model belongs to the technical field related to aluminum foil rolling mills, and specifically relates to an edge oil blocking device for an aluminum foil rolling mill. Background Art

[0002] The aluminum foil rolling mill is a device that rolls aluminum sheet coils with a thickness of less than 0.5mm through several passes to make it into aluminum foil with a thickness of more than 2×0.0045mm. During the rolling process, the edges of the aluminum foil are often subjected to greater stress, which can easily lead to damage to the roller surface or unstable aluminum foil quality. Therefore, chamfers are performed on both ends of the rolling section of the working rollers of the aluminum foil rolling mill. There is a large gap at the chamfers of the two corresponding rollers. During production, oil will be thrown outward along the working rotation direction, causing oil on the edges of the aluminum foil plate surface and affecting the processing quality of the aluminum foil rolling mill.

[0003] In view of this, the present utility model is proposed. Utility Model Content

A lower protective device 5 is fixedly mounted on the main support body 2 of the rolling mill at a position on the side of the lower roller 3 of the rolling mill. The upper protective device 4 and the lower protective device 5 are symmetrical about the center line between the upper roller 1 and the lower roller 3 of the rolling mill. The upper protective device 4 comprises a fixed seat plate 6, an upper mounting matching shaft 7, an oil blocking baffle 8, a flexible The upper shielding piece 20 and the upper locking nut 16, the fixed seat plate 6 is fixedly installed on the main support body 2 of the rolling mill by screws, and the upper mounting mating shaft 7 is fixedly installed on the fixed seat plate 6. A limited support platform 15 is fixedly set on the end of the upper mounting mating shaft 7 close to the fixed seat plate 6, and an upper rotating mating sleeve 14 is installed on the upper mounting mating shaft 7 outside the limited support platform 15. The upper rotating mating sleeve 14 is fixedly connected to one end of the oil blocking baffle 8, and an upper locking nut 16 is installed at the end position of the upper mounting mating shaft 7 away from the limited support platform 15 for locking the position of the oil blocking baffle 8.

[0027] Among them, an installation groove 21 is opened at the end of the oil blocking baffle 8 away from the upper rotating matching sleeve 14. The cross-section of the installation groove 21 is a T-shaped structure. The upper end position of the flexible shielding piece 20 is fixedly provided with a mounting end 22. The mounting end 22 is installed in the mounting groove 21. The size specifications of the mounting end 22 match the size specifications of the mounting groove 21. The flexible shielding piece 20 is used to contact with the rolling mill roller to avoid damage to the rolling mill roller.

[0028] Corresponding fixed countersunk holes 23 are processed on both side edges of the mounting groove 21. The fixed countersunk holes 23 are threaded holes, and fixing screws 24 are installed in the fixed countersunk holes 23. The upper plane of the flexible shielding plate 20 is tilted downward along the side close to the main support body 2 of the rolling mill, and the position of the flexible shielding plate 20 and the oil blocking baffle 8 is locked by the fixing screws 24.

[0029] An arc-shaped adjustment fitting groove 9 is opened below the fixed seat plate 6 with the installation fitting shaft 7 as the center. An auxiliary support rod 10 is fixedly provided on the bottom surface of the oil blocking baffle 8 on one side close to the fixed seat plate 6. A lower rotating fitting sleeve 18 is fixedly provided at the outer end position of the auxiliary support rod 10. The setting of the auxiliary support rod 10 can improve the structural stability of the oil blocking baffle 8.

[0030] A lower mounting fitting shaft 17 is provided in a sliding connection in the adjusting fitting groove 9. The cross-section of the adjusting fitting groove 9 is a convex structure. The mating ends of the lower mounting fitting shaft 17 and the adjusting fitting groove 9 are provided with a limiting end adapted to the adjusting fitting groove 9 to ensure that the lower mounting fitting shaft 17 can move along the adjusting fitting groove 9 without detaching from the adjusting fitting groove 9.

[0031] The lower rotating fitting sleeve 18 is installed on the outside of the lower mounting fitting shaft 17 , and a lower locking nut 19 is provided at the end of the lower mounting fitting shaft 17 for locking the relative position of the lower mounting fitting shaft 17 and the fixed seat plate 6 .

[0032] An installation chute 11 is processed on the main support body 2 of the rolling mill at a position below the fixed seat plate 6, and an upper oil collecting trough 12 and a lower oil collecting trough 13 are installed in the installation chute 11 accordingly. The sides of the upper oil collecting trough 12 and the lower oil collecting trough 13 are provided with a mounting block structure sliding connection that is compatible with the installation chute 11, which makes it easy to take out the oil collecting trough for cleaning.

[0033] The working principle of this utility model is: Figure 2 As shown, two sets of upper protection devices 4 are symmetrically provided at both ends of the upper roller 1 of the rolling mill, and two sets of lower protection devices 5 are symmetrically provided at both ends of the lower roller 3 of the rolling mill; Figure 3As shown, an upper oil collecting trough 12 is provided below the upper guard device 4, and a lower oil collecting trough 13 is provided below the lower guard device 5. The upper guard device 4 and the lower guard device 5 are symmetrical about the aluminum foil. When the inclination angle of the oil blocking baffle 8 is adjusted, the lower locking nut 19 and the upper locking nut 16 are loosened. When the oil blocking baffle 8 is rotated, the upper rotating matching sleeve 14 will rotate relative to the upper mounting matching shaft 7, so that the lower end of the flexible shielding piece 20 contacts the outer wall of the upper roller 1 of the rolling mill. During the adjustment process, the auxiliary support rod 10 will rotate synchronously with the oil blocking baffle 8, thereby causing the lower mounting matching shaft 17 to rotate along the adjustment matching groove 9. After adjustment, tighten the upper locking nut 16 and the lower locking nut 19. The double locking method can effectively improve the stability of the installation structure of the oil blocking baffle 8. In order to facilitate the oil on the oil blocking baffle 8 and the flexible shielding piece 20 to effectively fall into the upper oil collecting trough 12, the flexible baffle is tilted to the side close to the main support body 2 of the rolling mill;

[0034] The utility model has a reasonable structural design and is easy to install and use. An upper protective device 4 and a lower protective device 5 are respectively provided at the two end positions of the upper roller 1 and the lower roller 3 of the rolling mill. The protective devices can effectively protect the chamfered positions of the rolling mill rollers. The oil thrown out at the chamfered positions falls on the oil blocking baffle 8 and the flexible shielding sheet 20, which effectively protects and isolates the rolled aluminum foil, avoids the influence of the thrown oil on the surface quality of the aluminum foil, and solves the problem of oil on the edges of the aluminum foil during production. The flexible shielding sheet 20 is used to contact the outer surface of the rolling mill roller to avoid damage to the rolling mill roller. The inclination angle of the oil blocking baffle 8 can be adjusted as needed. Through the setting of the upper mounting mating shaft 7 and the lower mounting mating shaft 17, and the cooperation of the upper locking nut 16 and the lower locking nut 19, double locking is achieved to ensure the stability of the position and structure of the oil blocking baffle 8.

Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with this patent can make slight changes or modifications to equivalent embodiments using the above-mentioned technical content without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
