Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0061] Please refer to Figures 1 to 11The cold-rolled sheet slitting processing device provided by the application is described as follows. The cold-rolled sheet slitting processing device comprises a slitting machine a1, a winding machine a2, two guide plates 1, two adjusting mechanisms 2 and an edge trimming processing assembly. The slitting machine a1 is used to divide the cold-rolled sheet a3 into a plurality of steel strips a4 arranged side by side along the width direction. The winding machine a2 is used to wind the plurality of steel strips a4 simultaneously, realizing continuous and automatic production of the cold-rolled sheet a3 for automobile sealing strip skeleton, and significantly improving the production efficiency.

[0062] The two guide plates 1 are arranged side by side between the slitting machine a1 and the winding machine a2. Each guide plate 1 has a plurality of first strip-shaped holes 11 arranged at intervals along the arrangement direction of the steel strips a4. Each first strip-shaped hole 11 extends along the up-down direction to allow the steel strips a4 to pass through and twist the steel strips a4 into a vertical state with the side surface thereof facing the up-down direction. The first strip-shaped hole 11 can have a circular arc transition structure or a roller arranged therein to reduce the friction between the steel strip a4 and the first strip-shaped hole 11, thereby ensuring the smoothness of the steel strip a4 conveying.

[0063] The two adjusting mechanisms 2 are arranged on the two sides opposite to each other of the two guide plates 1 respectively and are used to interface with the plurality of steel strips a4 to twist the steel strips a4 from the horizontal state into the inclined state. By arranging the two guide plates 1 and the adjusting mechanisms 2, the steel strips a4 can be twisted from the horizontal state into the inclined state and further adjusted into the vertical state. This design can prolong the distance of the twisted part of the steel strips a4, thereby effectively avoiding the bending or even breaking of the steel strips a4 due to the too short distance of the twisted part.

[0064] According to the different materials to be processed, the adjusting mechanism 2 can flexibly adjust the inclination angle of the steel strips a4 according to the thickness and physical properties of the materials, thereby improving the practicability of the equipment.

[0065] The edge trimming processing assembly is arranged between the two guide plates 1 and is used to interface with the steel strips a4 in the vertical state to remove burrs on the edges of each steel strip a4. This step not only improves the appearance quality of the steel strips a4, but also reduces the safety hazards in subsequent processing and reduces the equipment wear or product defects caused by burrs.

[0066] In the embodiment of the present application, the cold-rolled sheet a3 first enters the slitting machine a1, and the slitting machine a1 divides the sheet into a plurality of parallel steel strips a4 along the width direction; the steel strips a4 remain in a horizontal state and move forward along the conveying direction; the slitting steel strips a4 enter between two parallel guide plates 1, each guide plate 1 is provided with a plurality of first strip-shaped holes 11, and the steel strips a4 pass through the corresponding first strip-shaped holes 11 respectively; before the steel strips a4 enter the guide plates 1, two adjusting mechanisms 2 act on both sides of the steel strips a4 respectively, the adjusting mechanisms 2 contact the steel strips a4, so that the steel strips a4 are gradually twisted from the horizontal state to the inclined state, and are prepared for the vertical state of the subsequent entering of the guide plates 1; after the action of the adjusting mechanisms 2 and the guide plates 1, the steel strips a4 are completely changed into the vertical state with the side upward, and continue to be conveyed forward in this state; the steel strips a4 in the vertical state enter the working area of the edge trimming processing assembly. The edge trimming processing assembly contacts the edges of the steel strips a4, removes the burrs on both sides of the steel strips a4, and ensures that the edges of the steel strips a4 are smooth and flat; finally, the steel strips a4 processed by the edge trimming processing assembly continue to be conveyed forward, and finally enter the winding machine a2, and the winding machine a2 can wind a plurality of steel strips a4 at the same time.

[0067] The slitting processing device for cold-rolled sheet provided in the embodiment of the present application can twist the slitting steel strips a4, thereby increasing the gap between adjacent steel strips a4, so as to facilitate the edge trimming processing assembly to polish the burrs on the edges of the steel strips a4, and improve the dimensional accuracy of the steel strips a4, compared with the prior art.

The engagement transmission mode of the gear rack 32 and the outer gear ring 31 has high transmission efficiency and stability, which can effectively avoid slipping or jamming during the adjustment process, ensuring reliable operation of the adjustment mechanism 2.

[0077] The gear rack 32 is connected to the mounting plate 21 by a pitch adjusting member 4 to adjust and fix the movement distance of the gear rack 32 relative to the mounting plate 21. The gear rack 32 is connected to the mounting plate 21 by the pitch adjusting member 4, which can accurately adjust the movement distance of the gear rack 32 and thus control the rotation angle of the rotating disc 22. This design makes the adjustment process more accurate and controllable, and the operator can quickly and accurately adjust the torsion angle of the steel belt a4 according to actual needs.
