[0027] The preferred embodiments of the present utility model will be described below with reference to the drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model.

[0028] The present utility model provides a cold-rolled steel plate polishing device, including;

[0029] Box body 1;

[0030] Through ports 2, a pair in number, are respectively formed in the two side walls of the box body 1;

[0031] Support plates are respectively fixedly installed on the outer wall surface of the box body 1 and below the pair of through ports 2. The lower end surface of the support plate is fixedly installed with a support rod, and the bottom end of the support rod is fixedly connected to the outer wall surface of the box body 1, which can support the support plate. The staff places the steel plate on one support plate and moves the steel plate from one through port 2 into the box body 1. At the same time, the other through port 2 facilitates the steel plate in the box body 1 to be moved out of the box body 1;

[0032] The first N-shaped frame 3 is fixedly installed in the box body 1;

[0033] Connecting blocks are respectively fixedly installed on the two side wall surfaces of the first N-shaped frame 3, and one end surface of the connecting block is fixedly connected to the inner wall surface of the box body 1, which can keep the first N-shaped frame 3 fixed;

[0034] The first rotating shaft 4 is rotatably installed in the first N-shaped frame 3;

[0035] The first polishing roller 5 is arranged on the outer surface of the first rotating shaft 4;

[0036] The first polishing roller 5 is fixedly installed on the outer surface of the first rotating shaft 4, and the first rotating shaft 4 drives the first polishing roller 5 to rotate, which can make the first polishing roller 5 polish the lower end surface of the steel plate in the box body 1;

[0037] The second N-shaped frame 6 is arranged above the first N-shaped frame 3;

[0038] The second rotating shaft 7 is rotatably installed in the second N-shaped frame 6;

[0039] The second polishing roller 8 is arranged on the outer surface of the second rotating shaft 7;

[0040] The second polishing roller 8 is fixedly installed on the outer surface of the second rotating shaft 7, and the second rotating shaft 7 drives the second polishing roller 8 to rotate, which can make the second polishing roller 8 polish the upper end surface of the steel plate in the box body 1. At the same time, a cleaning port is formed at the lower end of one side wall surface of the box body 1, which facilitates the staff to clean the residue of the steel plate accumulated on the lower end surface inside the box body 1. At the same time, a sealing door is hinged on the outer side wall surface of the box body 1 to seal the cleaning port;

[0041] The driving mechanism is arranged in the box body 1 and is used to drive the second N-shaped frame 6 to move.

[0042] Specifically, the driving mechanism includes;

[0043] The pressing plate 9 is arranged in the box body 1 and above the second N-shaped frame 6;

[0044] The threaded rod 10 is arranged inside the upper wall of the box body 1, and its bottom end is rotatably connected to the upper end surface of the pressing plate 9;

[0045] The elastic member 11 has one end fixedly connected to the upper end surface of the second n-shaped frame 6 and the other end fixedly connected to the lower end surface of the pressing plate 9;

[0046] The rotation of the threaded rod 10 can drive the movement of the pressing plate 9. The pressing plate 9 can move downward, which can drive the movement of the elastic member 11, so that the elastic member 11 can exert a downward pressure on the second n-shaped frame 6, making the second polishing roller 8 fit against the upper end surface of the steel plate for polishing.

[0047] Specifically, L-shaped frames 12 are fixedly installed on both sides of the pressing plate 9 on the upper end surface of the second n-shaped frame 6. The end of the L-shaped frame 12 away from the second n-shaped frame 6 contacts the upper end surface of the pressing plate 9;

[0048] The reverse rotation of the threaded rod 10 can drive the upward movement of the pressing plate 9. At the same time, the upper end surface of the pressing plate 9 contacts one end of the L-shaped frame 12. Under the action of the L-shaped frame 12, the second n-shaped frame 6 can be driven to move upward simultaneously.

[0049] Specifically, two pairs of limiting rods 13 are fixedly installed on the upper end surface of the second n-shaped frame 6. The tops of the limiting rods 13 sequentially penetrate through the pressing plate 9 and the upper wall of the box body 1;

[0050] Under the action of the limiting rods 13, the positions of the pressing plate 9 and the second n-shaped frame 6 can be limited to keep them stable during movement;

[0051] A limiting block 14 is fixedly installed at the top of the limiting rod 13;

[0052] The limiting block 14 can limit the sliding position of the limiting rod 13 to prevent its top from separating from the upper wall of the box body 1.

[0053] Specifically, a first motor 15 for driving the first rotating shaft 4 is provided on one side wall surface of the first n-shaped frame 3, and a second motor 16 for driving the second rotating shaft 7 is provided on one side wall surface of the second n-shaped frame 6;

[0054] The first motor 15 is fixedly installed on one side wall surface of the first n-shaped frame 3. At the same time, its output end is fixedly connected to one end surface of the first rotating shaft 4 and can drive its rotation. The second motor 16 is fixedly installed on one side wall surface of the second n-shaped frame 6. At the same time, its output end is fixedly connected to one end of the second rotating shaft 7 and can drive its rotation.

[0055] Working principle: First, the staff starts the first motor 15 and the second motor 16 simultaneously. At the same time, one end of the steel plate is inserted into the box body 1 through a through port 2. Meanwhile, the staff rotates the threaded rod 10. The rotation of the threaded rod 10 can drive the pressing plate 9 to move. The pressing plate 9 can move downward, which can drive the elastic member 11 to move, so that the elastic member 11 can exert a downward pressure on the second n-shaped frame 6, making the second polishing roller 8 fit with the upper end surface of the steel plate. At this time, the output end of the second motor 16 drives the second rotating shaft 7 and the second polishing roller 8 to rotate simultaneously to polish the upper end surface of the steel plate. At the same time, the rotation of the output end of the first motor 15 can drive the first rotating shaft 4 and the first polishing roller 5 to rotate simultaneously, which can polish the lower end surface of the steel plate. Under the action of the first polishing roller 5 and the second polishing roller 8, the upper and lower end surfaces of the steel plate can be polished simultaneously. At this time, the polished steel plate extends out through another through port 2, which is convenient for the staff to collect and brings convenience to people.
