[0021] The utility model provides the following Figure 1 , Figure 2 , Figure 3 The roller guide material blocking and centering limit mechanism shown includes a fixed box body 1, in which a bidirectional screw rod 2 is rotatably connected, the bidirectional screw rod 2 passes through the fixed box body 1 and is rotatably connected to the fixed box body 1 through a first bearing 11, thereby improving the stability of the bidirectional screw rod 2 during rotation, and both ends of the bidirectional screw rod 2 are fixedly connected to a rotating crank 3, and two sliding seats 4 slidably connected to the fixed box body 1 are threadedly connected on the bidirectional screw rod 2, and two guide rods 12 are fixedly connected to the fixed box body 1, and the two guide rods 12 pass through the sliding seat 4 and the sliding seat 4 is slidably connected to the guide rods 12, and the sliding seat 4 is guided by the guide rods 12, so that when the bidirectional screw rod 2 rotates, the sliding seat 4 can slide stably along the guide rods 12, and the tops of the two sliding seats 4 are fixedly connected with sliding connecting rods 5 passing through the top wall of the fixed box body 1, and the top wall of the fixed box body 1 is provided with guide grooves 13 for the sliding connecting rods 5 to pass through and slide.

[0022] A detachable fixing sleeve 6 is provided on the upper part of the sliding connecting rod 5 and the detachable fixing sleeve 6 is fastened to the sliding connecting rod 5 by a fastening bolt 7. A right-angle rod 8 is fixedly connected to the top of the detachable fixing sleeve 6. One end of the right-angle rod 8 is rotatably connected to a lower pressure wheel 9. One end of the right-angle rod 8 is rotatably connected to the lower pressure wheel 9 through a second bearing 14.

[0023] Both ends of the fixed box body 1 are fixedly connected with mounting components 10, and the mounting component 10 includes a column 10.1 fixedly connected to the fixed box body 1, the top of the column 10.1 is rotatably connected to a support plate 10.2, the support plate 10.2 is threadedly connected with a screw 10.3, the top of the screw 10.3 is fixedly connected to a rotating block 10.4, the bottom of the screw 10.3 is rotatably connected to a pressure plate 10.5, the top of the column 10.1 is rotatably connected to the support plate 10.2 through a bearing 10.6, and the bottom of the screw 10.3 is rotatably connected to the pressure plate 10.5 through a bearing 2 10.7.

[0024] Working principle: When the utility model is implemented, the fixed box body 1 is first placed under the roller, and the sliding connecting rod 5 extends to the top of the roller through the gap between the two driving rollers. At the same time, the two columns 10.1 on the fixed box body 1 are respectively located on both sides of the roller, and then the support plate 10.2 is rotated to make it rotate above the side baffles on both sides of the roller, and then the rotating block 10.4 is rotated to drive the screw rod 10.3 to rotate. Since the screw rod 10.3 is threadedly connected with the support plate 10.2, when the screw rod 10.3 rotates, the screw rod 10.3 will slide downward, and the screw rod 10.3 is rotationally connected with the pressure plate 10.5 through the bearing 10.7. Therefore, the downward sliding of the screw rod 10.3 will drive the pressure plate 10.5 to move downward, so that the pressure plate 10.5 moves to the top of the contact side baffle for clamping and fixing, thereby realizing the installation and fixation of the limit mechanism, and the operation is simple and convenient; then the detachable fixing sleeve 6 is installed on the top of the sliding connecting rod 5, and the connection is fastened by the fastening bolt 7, and then the rotating crank 3 is controlled to rotate, driving the bidirectional screw rod 2 to rotate, and the rotation of the bidirectional screw rod 2 drives the two sliding seats 4 to slide toward or away from each other, so that the position of the two lower pressure wheels 9 can be adjusted, which can be suitable for limiting steel plates of different widths, and can make the steel plate in the middle area to avoid deviation.
