Technical Field
[0001] The utility model relates to the technical field of cold-rolled plate production, in particular to a cold-rolled plate trimming device with a protection mechanism. Background Art
[0002] Cold-rolled sheet is a common product in metal processing and is widely used in the manufacturing industry. The production process of cold-rolled sheet includes raw material preparation, rolling, annealing and trimming.
[0003] Since the edges of cold-rolled sheets are often irregular during the rolling process, trimming is required to trim the edges of the sheets and ensure that they are flat. In the prior art, the trimming device cannot tighten the steel strips when tying them, so that there are certain gaps between the layers of steel strips, which makes the steel strips as a whole easy to loosen and inconvenient to store; and when the cold-rolled steel strips are tyed to the tail end, the tail end of the cold-rolled steel strips will also swing left and right on the ground during the process of rolling from one end of the reel to the other end. Since the edges of the cold-rolled steel strips are sharp, it is very easy to cause danger to the staff.
[0004] The patent with authorization announcement number CN 208178604 U discloses a fixed trimming device for cold-rolled steel strips, which can solve the problem of loose steel strips to a certain extent, but cannot solve the problem of left and right swinging of the tail end of the cold-rolled steel strips, and there is still a certain degree of danger.

[0008] Preferably, the protective transverse plate is connected to the first folding plate and the second folding plate in sequence, and the second folding plate is connected to the protective connecting plate.
[0009] Preferably, three telescopic shafts are provided, and a spring is sleeved on the middle telescopic shaft.
[0010] Preferably, the length of the protective cross plate is slightly smaller than the distance between the two shaft plates.
[0011] The length of the protective cross plate is 2-10 mm shorter than the distance between the two shaft plates.

[0022] See also Figure 1 The cold-rolled plate trimming device with a protective mechanism in the utility model includes a trimmer 42, on which a cold-rolled plate 41 is placed. Through the action of the trimmer 42, the edge of the cold-rolled plate 41 is cut to form a cold-rolled steel strip 4.
[0023] A reel 1 is disposed on one side of the trimming machine 42, and shaft plates 11 are disposed at both ends of the reel 1. The reel 1 between the two shaft plates 11 has a preset length and is used to wrap the cold-rolled steel strip 4. One end of the reel 1 passes through the shaft plate 11 and the first fixed block 12 and is connected to the first rotating motor 13, which is disposed on the first fixed block 12; the reel 1 is driven to rotate by the first rotating motor 13, and the reel 1, the shaft plate 11, and the first rotating motor 13 are supported and fixed by the first fixed block 12.
[0024] The trimming device also includes a protective transverse plate 2, which is arranged along the axial direction of the reel 1 and abuts against the cold-rolled steel strip 4; the protective transverse plate 2 is connected to the first folding plate 24 and the second folding plate 25 in sequence, the second folding plate 25 is connected to the protective connecting plate 21, the protective transverse plate 2 is connected to the protective connecting plate 21, and a plurality of telescopic shafts 22 are arranged between the protective connecting plate 21 and the first fixed block 12, and a spring 23 is sleeved on the telescopic shaft 22.
[0025] When the spring 23 is at a free length, the length of the telescopic shaft 22 is the shortest, and the protective cross plate 2 is close to the reel 1; when the thickness of the cold-rolled steel strip 4 wound on the reel 1 increases, the reel 1 becomes thicker, pushing the protective cross plate 2 outward, and the spring 23 passively becomes longer; due to the action of the spring 23, the protective cross plate 2 can always abut against the surface of the cold-rolled steel strip 4 and has a certain pressure, preventing the cold-rolled steel strip 4 from loosening easily during the winding process.
[0026] In the utility model, three telescopic shafts 22 are provided, and a spring 23 is sleeved on the middle telescopic shaft 22 .
[0027] Preferably, the length of the protective transverse plate 2 is slightly smaller than the distance between the two shaft plates 11. In the present invention, the length of the protective transverse plate 2 is 2-10 mm smaller than the distance between the two shaft plates 11, so that the protective transverse plate 2 can fully abut against the outer surface of the cold-rolled steel strip 4, exerting pressure on the cold-rolled steel strip 4 wound on the reel 1, so that the cold-rolled steel strip 4 is tightly wound.
[0028] Preferably, see Figure 1 and Figure 2 The trimming device also includes a protective sleeve 3, a cold-rolled steel strip 4 is passed through the protective sleeve 3, the protective sleeve 3 is arranged on the feeding side of the cold-rolled steel strip 4, and the distance between the protective sleeve 3 and the reel 1 is 30-60 cm; the protective sleeve 3 is fixedly connected to a moving block 31, the moving block 31 is threadedly sleeved with a lead screw 32, and the lead screw 32 is connected to a second rotating motor 34.

[0031] The second rotating motor 34 works to drive the lead screw 32 to rotate, and the moving block 31 moves together with the protective sleeve 3 along the axial direction of the lead screw 32, thereby driving the cold-rolled steel strip 4 to roll from one end of the reel 1 to the other end.
[0032] The working principle of the utility model is:
[0033] The cold-rolled steel strip 4 is coiled and bundled by rotating the reel 1. During the bundling process, the protective cross plate 2 abuts against the surface of the cold-rolled steel strip 4 under the action of the spring 23 and the telescopic shaft 22, and forms pressure to prevent the cold-rolled steel strip 4 from being loosely bundled. At the same time, the protective cover 3 moves left and right, driving the cold-rolled steel strip 4 from one end of the reel 1 to the other end, so that the cold-rolled steel strip 4 is evenly bundled, and the protective cover 3 can carefully limit the cold-rolled steel strip 4 to prevent the tail end of the cold-rolled steel strip 4 from swinging left and right.
[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
