Description

Technical Field

[0001] The utility model relates to the technical field of strip steel shearing, in particular to a slitting machine used for strip material shearing. Background Art

[0002] Strip is a long strip of metal or non-metallic material, usually with a small width and a large length. During the production process, the strip usually needs to be cut using a slitting machine. A slitting machine is a tool used to cut metal coils or plates into the required width or size along the length direction. It cuts the strip with a high-speed rotating blade or scissors to achieve precise size control and efficient production.

[0003] When existing slitting machines are shearing strips, the strips may deviate during the transmission process. This deviation will not only affect the accuracy of the shearing position of the strip, resulting in quality problems such as uneven shearing surface and excessive burrs, but also cause the slitting machine to frequently stop to adjust the position of the strip, thereby affecting production efficiency. For example, the slitting machine for cutting air-conditioning bracket plates disclosed in the announcement number CN211804103U does not have a steel plate limiting structure. Due to the lack of a limiting plate to clamp and position the two sides of the steel plate, the steel plate may deviate during the transmission process due to tension, vibration or operation error. This deviation will directly affect the shearing accuracy, resulting in problems such as uneven cutting edges and inaccurate dimensions.

[0004] Therefore, it is necessary to invent a slitting machine for strip shearing to solve the above problems. Utility Model Content

[0028] Working principle of this utility model:

[0029] Refer to the instruction manual Figure 1-2 When using the utility model, first, the strip to be sheared is guided by the conveying wheel 3 and the guide roller 4 to enter the area of ​​the No. 1 conveying roller 6. The No. 1 conveying roller 6 stably conveys the strip forward to the shearing area. When the strip is transmitted to the shearing area, the cylinder 8 pushes the mounting plate 9 to move downward, so that the No. 1 pressing roller 10 and the No. 2 pressing roller 11 press the strip. The pressing operation ensures that the strip will not deviate or shake during the shearing process, thereby improving the shearing accuracy.

[0030] Refer to the instruction manual Figure 3-5 When using the utility model, the rotating motor 16 then drives the shearing roller 15 to rotate, and the knife body on the shearing roller 15 cooperates with the knife groove on the supporting roller 17 to shear the strip. When the strip is placed on the supporting roller 17, the bidirectional lead screw 19 is driven by the driving motor 21 to rotate, so that the limit plate 18 threadedly connected to the bidirectional lead screw 19 slides along the slide bar 20. The movement of the limit plate 18 can clamp and position the two sides of the strip. Thus, the limit plate 18 limits the position of the strip during the shearing process, thereby achieving the accuracy of the strip shearing. After the strip shearing is completed, the strip is output through the No. 2 conveyor roller 22 to complete the entire shearing process.
