[0018] Figure 3 This is a side view of the main roller lower support structure of this utility model. Detailed Implementation
[0019] like Figure 1-3 As shown, a micro-adjustment device for adjusting the height of a main roller includes an adjusting cylinder 1 and a cylinder seat 2. The cylinder seat 2 is fixed to one end of an adjusting bracket 3. An adjusting inclined block 4 is fixed to the telescopic end of the adjusting cylinder 1. The adjusting inclined block 4 is slidably mounted on a support guide plate 5 at the other end of the adjusting bracket 3. An adjusting guide plate 6 is mounted on the inclined surface of the adjusting inclined block 4. The support slider 8 at the bottom of the main roller lower support 7 is slidably supported on the adjusting guide plate 6 through the inclined surface. A main roller 9 is mounted on the main roller lower support 7. The main roller lower support 7 is vertically slidably mounted on a fixed guide plate and in a dovetail groove in the lower half of the frame 10.
[0020] The frame 10 on one side of the main roller support 7 is provided with a locking cylinder 11 for tightening and locking the main roller support 7. The extension end of the locking cylinder 11 drives the locking structure to make the outer wall of the main roller support 7 in close contact with it. The top of the adjusting bracket 3 is provided with a limit slot, and the limit key 12 provided on the frame 10 is located in the limit slot. The upper side wall of the adjusting bracket 3 is fixedly connected to the bottom of the frame 10.
[0021] The telescopic end of the adjusting cylinder 1 is fixedly connected to the fixed end of the adjusting inclined block 4 through the pressure ring 13. The pressure ring 13 is fixedly sleeved on the telescopic end of the adjusting cylinder 1. The pressure ring 13 is fixedly connected to the fixed end of the adjusting inclined block 4 through bolts. The outer end of the adjusting inclined block 4 extends to the outer end of the adjusting bracket 3. The outer wall of the adjusting bracket 3 at the outer end of the adjusting inclined block 4 is provided with a protective cover 14 covering the adjusting inclined block 4.
[0022] The upper end of the main roller 9 passes through the upper support 15 of the main roller, and the upper support 15 of the main roller is tightened and fixed on the frame 10 by the guide rail plate 16. The opposite side of the left and right guide rail plates 16 is an inward inclined slope. The upper support 15 of the main roller is tightened and fixed by the slider structure between the inclined structures of the left and right guide rail plates 16, and the main roller can move up and down along the left and right guide rail plates 16 by the lower support 7.
[0023] A vertical stud 17 is fixed in the mounting hole on one side of the bottom of the frame 10. A locking nut 18 for locking the lower support 7 of the main roller is provided at the upper end of the stud 17. A positioning plate 19 is fixed by a hexagonal bolt at the upper end of the frame 10, and the positioning plate 19 extends to the upper end of the upper support 15 of the main roller to limit the upper end of the upper support 15 of the main roller. An upper sleeve 20 is provided inside the upper support 15 of the main roller, and a positioning key 21 located in the groove of the main roller 9 is provided inside the upper sleeve 20.
[0024] Working principle of this utility model:
[0025] Positioning plate 19, hexagonal bolts, and locking cylinder 11 are always locked and fixed. Whether the equipment is working or the main roller mold is being adjusted, the upper support 15 of the main roller is always locked. When fine-tuning of the main roller position is required, the lower locking cylinder 11 of the main roller 9 is released via hydraulic-electric control, the locking nut 18 is loosened with a special wrench, and the adjusting cylinder 1 is extended or retracted via electro-hydraulic control to push the adjusting wedge 4 forward and backward, thereby adjusting the position of the lower support of the main roller and the main roller. At this time, there is relative displacement between the lower support 7 of the main roller and the adjusting pad 22, and relative displacement between the upper end of the main roller 9 and the upper sleeve 20. After the main roller position is adjusted, the lower locking cylinder 11 of the main roller 9 is re-locked, and the locking nut 18 is pre-tightened with a wrench. This completes one adjustment of the main roller position. This utility model uses an electrical control system to control the retraction and extension of the hydraulic cylinder to complete the up-and-down fine-tuning of the main roller (adjustment range 0-20mm).
[0026] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
