[0023] like Figures 1 to 4 As shown, this embodiment provides a telescopic support structure for convenient strip threading, including a movable guide plate 2 located on the outlet side of the working roll 1 at the outlet of the rolling mill, the movable guide plate is installed on the frame 3, and is driven by a driving mechanism to reciprocate forward and backward along the strip threading direction, the upper surface of the movable guide plate is provided with a first comb tooth area 4, the first comb tooth area is composed of a plurality of first upper convex ribs spaced apart from each other on the left and right, and the first upper convex ribs all extend along the strip threading direction.
[0024] In the embodiment of the utility model, the movable guide plate is fastened with a copper strip 5 by screws at the front edge close to the working roller, and the upper surface of the front edge of the copper strip gradually tilts downward from top to bottom toward the working roller.
[0025] In the embodiment of the utility model, a first oil drain channel 6 is formed between two adjacent first upper ribs on the left and right sides, the front groove port of the first oil drain channel is blocked and closed by a copper bar, and the rear groove port of the first oil drain channel is open.
[0026] In the embodiment of the utility model, the left and right ends of the movable guide plate are connected to the frame via a slider and rail moving pair 7, and the guiding direction of the slider and rail moving pair is the front-back direction.
[0027] In the embodiment of the utility model, the movable guide plate is connected to the frame via the fixed guide plate. The bottom surface of the movable guide plate is provided with a movable slide groove 9 for the fixed guide plate to be embedded in. The front side of the fixed guide plate is embedded in the movable slide groove and the rear side is fixed to the frame.
[0028] In the embodiment of the utility model, the fixed guide plate is composed of a front low horizontal section 10, a middle inclined section 11, and a rear high horizontal section 12 from front to back.
[0029] In an embodiment of the utility model, the front low horizontal section is used to embed into the movable slide groove and its upper surface is lower than the upper surface of the movable guide plate. The middle inclined section is used to connect the front low horizontal section and the rear high horizontal section and gradually inclines upward from front to back. The upper surface of the rear high horizontal section is higher than the upper surface of the front low horizontal section.
[0030] In the embodiment of the utility model, a second comb tooth area 13 is provided on the upper surface of the rear high horizontal section.
