AI Technical Summary
In the prior art, the entrance guide structure of a three-roll mill suffers severe wear after long-term use. The lack of a limiting structure makes it impossible to adjust the position of the guide wheel, stably support the workpiece, and adapt to the guide requirements of workpieces of different sizes.
A guide structure including a base, a fixing ring, a mounting frame, an adjustment mechanism, and a locking mechanism is designed. The adjustment mechanism enables the adjustment and locking of the guide roller position, while the extension rod, positioning frame, and locking assembly enable the flexible installation and removal of the guide roller.
It achieves stable guidance for workpieces of different sizes, facilitates the disassembly and installation of guide rollers, and improves the adaptability and service life of the guide structure.

Abstract
Claims
1. A mill entry guide structure comprising a base (1), characterised in that: The base (1) is fixedly connected to the top of a fixing ring (11), and the fixing ring (11) is provided with an installation frame (12) on its inner circumference. A fixing bolt (13) is provided through the middle of the installation frame (12). The fixing bolt (13) is slidably connected to the installation frame (12). A fixing nut (14) is threaded to the end of the fixing bolt (13). A guide roller (15) is rotatably provided on the outer circumference of the fixing bolt (13). An adjustment mechanism (2) is provided on one side of the mounting frame (12). The adjustment mechanism (2) is used to conveniently adjust the position of the mounting frame (12) at the same time. The adjustment mechanism (2) includes a mounting groove (21), an extension rod (22) and a positioning frame (23). The mounting groove (21) is opened on the surface of the fixing ring (11), and a limiting shaft (24) is fixedly connected inside the mounting groove (21). The extension rod (22) is disposed in the mounting groove (21). A limiting groove (25) is provided through the middle of the extension rod (22). The limiting groove (25) is sleeved on the outer periphery of the limiting shaft (24). The limiting groove (25) is movably connected to the limiting shaft (24). A positioning shaft (26) is also provided through the middle of the extension rod (22). The end of the extension rod (22) is fixedly connected to the mounting frame (12). The positioning frame (23) is U-shaped. The end of the positioning frame (23) is fixedly connected to the inner circumference of the fixing ring (11). The positioning frame (23) has a positioning groove (27) on its edge. The positioning groove (27) is set in multiple groups, and the number of positioning grooves (27) in each group is set to two. The positioning groove (27) matches the positioning shaft (26). The inner circumference of the fixing ring (11) is provided with a locking mechanism (3), which is used to lock multiple mounting frames (12) at the same time.
2. A mill entry guide structure as claimed in claim 1, characterised in that: The locking mechanism (3) includes a rotating ring (31), the outer periphery of which is rotatably connected to a fixed ring (11), and a fixing bolt (32) is threadedly connected to the surface of the rotating ring (31). The inner periphery of the rotating ring (31) is provided with multiple locking components (33), and the multiple locking components (33) are respectively corresponding to multiple adjusting mechanisms (2).
3. A mill entry guide structure as claimed in claim 2, characterised in that: The locking assembly (33) includes a locking hole (331) and a fixing rod (332). The locking hole (331) is opened on the surface of the adjacent positioning frame (23), and the number of the locking holes (331) is set to two. The end of the fixed rod (332) is fixedly connected to the rotating ring (31), and a locking rod (333) is fixedly connected to the side wall of the fixed rod (332). The locking hole (331) and the limiting groove (25) are both matched with the locking rod (333).
4. A mill entry guide structure as claimed in claim 3, characterised in that: The locking rod (333) is arc-shaped, and the end of the locking rod (333) is chamfered.
5. A mill entry guide structure as claimed in claim 1, characterized in that: The extension rod (22) has a gripper (4) at the end away from the mounting frame (12), and the gripper (4) is cylindrical.
