Description

Technical Field

[0001] This utility model relates to the field of slitting machine technology, and in particular to a blade adjustment mechanism for a slitting machine. Background Technology

[0002] A slitting machine is a widely used piece of machinery in industrial production. It is primarily used to precisely cut large-format materials to set dimensions, commonly found in the processing of materials such as paper, film, metal foil, plastics, and textiles. The core function of a slitting machine is to use efficient and precise cutting technology to cut raw materials into the required width or length to meet the needs of subsequent production or packaging.

[0003] During production and processing, slitting machines mostly use multiple blades that are fixed at equal intervals to cut raw materials into multiple segments. However, the required slitting width varies depending on the raw material and the processing needs. The fixed blades make it difficult to flexibly adjust the slitting distance according to the processing requirements of the raw material, which greatly reduces the flexibility of the slitting machine.

It is used to drive the cutting adjustment mechanism and the first blade 7 to move downward, so as to facilitate the cutting of the raw materials.

[0022] Specifically, the drive mechanism consists of a servo motor 17, a drive wheel 18, a transmission belt 19, and a driven wheel 20.

[0024] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0025] In use: First, the raw material to be cut is pulled between multiple feeding rollers 2 and the surface of the auxiliary roller 3 and clamped and fixed between multiple traction rollers 22. Start the dual-axis motor 8 to drive the threaded rod 9 to rotate. Through the threaded connection between the threaded rod 9 and multiple threaded sleeves 11, and with the different pitches of the two sections of the threaded rod 9, multiple second blades 12 can be driven to move synchronously at different speeds to cooperate with the first blade 7 to adjust the cutting width at equal intervals. After the adjustment is completed, start the drive motor 21 to drive the traction rollers 22 and the transmission gears 23 to rotate. Through the mutual meshing of multiple transmission gears 23, multiple traction rollers 22 are driven to rotate relative to each other along the inner wall of the fixed frame 1, which can pull the raw material to the right. Start the servo motor 17 to drive the drive wheel 18 and the transmission belt 19 to rotate. Through the meshing of the transmission belt 19 and the driven wheel 20, the transmission shaft 14 and the gear 15 are driven to rotate along the inner wall of the fixed ring 13. Through the meshing of the gear 15 and the rack 16, the limit slider 4, the connecting plate 5, the first blade 7 and the second blade 12 are driven to move downwards to contact the raw material, so that the moving raw material can be cut at equal intervals.

[0026] In summary, the blade adjustment mechanism of this slitting machine pulls the raw material through multiple feed rollers 2 and the surface of the auxiliary roller 3 into the traction assembly for clamping and fixing. The dual-axis motor 8 drives the slitting adjustment mechanism to move synchronously at different speeds, allowing for equidistant adjustment of the cutting width in conjunction with the first blade 7. The traction assembly pulls the raw material to the right, and the drive mechanism, through the lifting assembly, limit slider 4, and connecting plate 5, drives the first blade 7 and the slitting adjustment mechanism downwards to contact the raw material, thus performing equidistant slitting of the moving material. This achieves the goal of facilitating automatic adjustment of the slitting distance, avoiding the problem of existing slitting machines having relatively fixed slitting distances, which makes it difficult for the slitting machine to adapt to different widths of slitting work and greatly reduces its flexibility. This addresses the problems mentioned in the background art.
