[0022] The lifting assembly 8 includes a connecting plate 81, a lifting rod 82, a cylinder 83, a cylinder push rod 84, a clamping seat 85 and a clamping block 86. The two roller sleeves 6 at the top are fixedly connected by two connecting plates 81. The tops of the two connecting plates 81 are fixedly connected with the lifting rods 82. The frame 1 is fixedly connected with a cylinder 83. The inner side of the cylinder 83 is slidably connected with a cylinder push rod 84 having one end penetrating and extending to the top of the frame 1. The top of the cylinder push rod 84 is fixedly connected with a clamping seat 85. The inner side of the clamping seat 85 is fixedly connected with a clamping block 86. The clamping blocks 86 are respectively fixedly connected to the inner sides of the two lifting rods 82.

[0023] The lifting assembly 9 includes a fixed seat 91, a sliding seat 92, a first articulated seat 93, a lifting seat 94, a second articulated seat 95, a mounting seat 96 and an electric push rod 97. The frame 1 is fixedly connected with the fixed seat 91, and the outer side of the fixed seat 91 is slidably connected with the sliding seat 92. The top of the sliding seat 92 contacts the bottom ends of the two roller sleeves 6 below. The left end of the sliding seat 92 is fixedly connected with the first articulated seat 93, the inner side of the sliding seat 92 is slidably connected with the lifting seat 94, and the right end of the lifting seat 94 is fixedly connected with the second articulated seat 95. Mounting seats 96 are provided at both left and right ends of the frame 1, and electric push rods 97 are fixedly connected to the inner sides of the two mounting seats 96. The moving end of the electric push rod 97 on the left is hinged to the inner side of the first articulated seat 93, and the moving end of the electric push rod 97 on the right is hinged to the inner side of the second articulated seat 95.

[0024] Through the above arrangement, when it is necessary to adjust the size of the rolled steel strip, the cylinder 83 can be started, and the cylinder push rod 84 can be pushed out (or retracted), driving the clamping seat 85 and the clamping block 86 to move upward (or downward), so that the two lifting rods 82 move upward (or move downward at the same time), thereby driving the two roller sleeves 6 to move upward (or move downward at the same time), and finally the upper driven roller 7 moves upward (or moves downward), thereby changing the distance between the upper driven roller 7 and the active roller 4, and at this time, the two electric push rods 97 are started at the same time, and the moving ends of the two electric push rods 97 are pushed out (or retracted) at the same time, and the slide seat 92 moves along the outer side of the fixed seat 91 to The lifting seat 94 slides to the upper right (or lower left) along the inner side of the slide seat 92, thereby lifting (or moving down) the two roller sleeves 6 below, and finally changing the spacing between the driven roller 7 and the active roller 4 below. It should be noted that the two driving shafts 3 and the two connecting shafts 5 are connected to the driving mechanism through a pulley mechanism (not shown in the figure). After starting the driving mechanism, the two driving shafts 3 and the two connecting shafts 5 can be driven to rotate, thereby rotating the two active rollers 4. The steel strip can be rolled when passing between the active roller 4 and the driven roller 7, and changing the spacing between the active roller 4 and the driven roller 7 can change the thickness of the rolled steel strip.

[0025] Reference Figure 1-3 , wherein the slide seat 92 is provided with two slide grooves 10, the fixed seat 91 and the lifting seat 94 are respectively slidably connected to the inner sides of the two slide grooves 10, the two slide grooves 10 are both inclined, and the inclination angles of the two slide grooves 10 are the same;

[0026] Through the above-mentioned structural setting, the two slide grooves 10 are both inclined and have the same inclination angle, which can ensure that when the moving ends of the two electric push rods 97 are pushed out or retracted at the same time, the slide 92 can slide smoothly to the upper right or lower left. During the sliding process, the top surface of the slide 92 is always parallel to the horizontal plane, avoiding the deviation of the driven roller 7 below.
