Description

Technical Field

[0001] The utility model relates to the technical field of light guide plate processing, in particular to a light guide plate rolling device. Background Art

[0002] The existing hot roller printing method is to roll the light guide plate after extrusion to form a dot structure on its surface. The conventional light guide plate hot press machine sets the hot pressing roller at a relatively high position, mainly because the upper roller is fixed and the device for adjusting the height of the lower roller is set at the lower side of the lower roller. Please refer to the patent with authorization announcement number CN220314174U. This results in a higher discharge port between the two rollers, so that workers must stand on the workbench to operate, which needs to be improved. Utility Model Content

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the protection scope of the utility model.

[0016] like Figure 1-Figure 4As shown, a light guide plate rolling device comprises a base 1, a door frame 2, an upper roller 3, an upper shaft seat 4, a lower roller 5, a lower shaft seat 6, an upper motor 7, a lower motor 8 and an adjusting device. A pair of door frames 2 are fixedly mounted on the base 1, an upper shaft seat 4 is fixedly mounted on the top of the door frame 2, and a lower shaft seat 6 is slidably mounted on the door frame 2 along the longitudinal direction. Preferably, a guide groove 21 is longitudinally arranged on the door frame 2, and the upper shaft seat 4 is fixed to the upper part of the guide groove 21 by bolts. An upper roller 3 is mounted between the two upper shaft seats 4, and a lower roller 5 is mounted between the two lower shaft seats 6. An upper motor 7 and a lower motor 8 for driving the upper roller 3 and the lower roller 5 are respectively mounted on the upper shaft seat 4 and the lower shaft seat 6. The device includes an upper wedge block 9, a lower wedge block 10 and an adjusting rod 110. The lower wedge block 10 is installed on the bottom wall of the guide groove 21 along the transverse sliding direction. The upper wedge block 9 is matched with the lower wedge block 10. The upper wedge block 9 is slidably fitted in the guide groove 21, and the upper wedge block 9 is fixed to the bottom of the lower shaft seat 6 by bolts.
