Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for color steel plate production lines, in particular to slitting and rewinding equipment in color steel plate production lines, and in particular to a steel coil cutting and recycling mechanism. Background Art

[0002] During the processing of color-coated steel sheets, due to varying product specifications, the raw material, or steel coils, must be cut and slit to meet the required product size specifications. This slitting process inevitably produces leftover scraps, which are currently piled aside, affecting the cleanliness of the workshop and the management of the scrap transport. CN221473742 U discloses a steel coil cutting device with a rational design. It utilizes water to not only cool the cutting process but also remove the cutting debris into a recycling bin. However, this device can only collect smaller scraps, such as scraps, and cannot meet the collection and recycling needs of larger sheet materials.

[0003] Therefore, it is of great practical significance to develop a cutting and recycling mechanism that can meet the needs of collecting and recycling larger-sized plates. Utility Model Content

[0004] Due to the above-mentioned defects in the prior art, the present invention provides a steel coil cutting and recycling mechanism that meets the needs of collecting and recycling larger-sized plates, so as to solve the problem that the existing steel coil cutting device cannot meet the needs of collecting and recycling larger-sized plates.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A steel coil cutting and recycling mechanism, comprising a cutting and slitting part and a side material rewinding and recycling part;

[0007] The cutting and slitting section includes a cutting and slitting section frame, on which an active cutting roller and a driven cutting roller are arranged up and down, and the active cutting roller and the driven cutting roller are installed with multiple groups of cutting knives arranged in a staggered manner, and a cutting drive motor is also installed on the cutting and slitting section frame, and the cutting drive motor is connected to the active cutting roller through a cutting transmission belt;

[0008] The cam is provided with a spring which is fixed to the drive shaft of the said machine shaft, and a spring which is provided on the cam to allow the cam to move forward and backward, so that the cam can move along the said cam and move along the said driving shaft of the said machine shaft can move along the said cam.

[0009] The steel coil cutting and recycling mechanism of the utility model has a reasonable structural design, which organically combines the steel coil cutting device and the recycling device. The cutting device uses the cutting drive motor as the power source to drive the active cutting roller to roll, and the plate is inserted between the active cutting roller and the driven cutting roller. The plate moves forward as the active cutting roller rolls, thereby driving the driven cutting roller to roll, and the cutting tools on the two cutting rollers run to cut the plate; the edge material rewinding and recycling part transmits torque to the connecting plate through the friction force between the friction plate and the driven sprocket, thereby driving the main shaft to rotate. Since the diameter of the edge material gradually increases during winding, the linear speed of the material collection gradually increases, but when it is too large, relative sliding will occur between the friction plate and the driven sprocket to avoid interference between the linear speed of the material collection and the shearing speed of the material collection, thereby ensuring stable material collection and good application prospects.

[0010] As the preferred technical solution:

[0011] In the steel coil cutting and recycling mechanism described above, bearing blocks are installed on both sides of the cutting and slitting unit frame, and the active cutting roller and the driven cutting roller are installed on the bearing blocks. The gap between the cutting blades on the two cutting rollers can be adjusted through the bearing blocks.

[0012] In the steel coil cutting and recycling mechanism as described above, multiple groups of cutting tools are arranged at equal distances on the active cutting roller and the driven cutting roller.

[0013] In the aforementioned steel coil cutting and recycling mechanism, the outer wall of the main shaft is provided with an external thread structure that matches the spring retaining nut, and the spring retaining nut is threadedly connected to the main shaft. By controlling the position of the spring retaining nut, the compression of the compression spring is controlled (the tighter the spring is compressed, the greater the force, the greater the friction, and the less likely the friction plate is to slide relative to each other), thereby controlling the speed difference between the friction plate and the driven sprocket when they slide relative to each other.

[0014] In the steel coil cutting and recycling mechanism as described above, the limiting holes are strip-shaped through holes arranged along the length direction of the main shaft.

[0015] In the steel coil cutting and recycling mechanism as described above, the main shaft is provided with side plates and side frames, which are respectively located on both sides of the material receiving rack, and the material receiving rack is limited by the side plates and side frames.

[0016] In the steel coil cutting and recycling mechanism as described above, the side plates and side frames are provided with mutually matching latch hole groups, and the latches are plugged into the latch hole groups to prevent the side plates and side frames from rotating relative to each other when the main shaft rotates.

[0017] In the steel coil cutting and recycling mechanism as described above, a locking nut for limiting the side frame is threadedly connected to the main shaft.

[0018] The above technical solution is only a feasible technical solution of the present invention. The protection scope of the present invention is not limited to this. Those skilled in the art can reasonably adjust the specific design according to actual needs.

[0019] Compared with the prior art, the above utility model has the following advantages or beneficial effects:

[0020] (1) The steel coil cutting and recycling mechanism of the utility model has a reasonable structural design, which organically combines the steel coil cutting device and the recycling device;

[0021] (2) The steel coil cutting and recycling mechanism of the utility model uses a cutting drive motor as a power source to drive the active cutting roller to roll. The plate is inserted between the active cutting roller and the driven cutting roller. The plate moves forward as the active cutting roller rolls, thereby driving the driven cutting roller to roll. The cutting tools on the two cutting rollers operate to cut the plate. The design is reasonable.

[0022] (3) In the steel coil cutting and recycling mechanism of the present invention, the edge material rewinding and recycling part transmits torque to the connecting plate through the friction between the friction plate and the passive sprocket, thereby driving the main shaft to rotate. As the edge material diameter gradually increases during rewinding, the rewinding linear speed gradually increases. However, when it is too large, relative sliding will occur between the friction plate and the passive sprocket to avoid interference between the rewinding linear speed and the rewinding shearing speed, thereby ensuring stable rewinding and having good application prospects.
