Abstract
Description
Technical Field
[0001] This utility model relates to a copper foil slitting device, and more specifically, to a copper foil slitting device with a dust removal mechanism. Background Technology
[0002] After copper foil is produced, it needs to be slit into products of various widths according to customer requirements. During the slitting process, copper dust is generated. In current slitting machines, a negative pressure suction nozzle is usually installed next to the cutter to remove the dust. However, the small copper dust particles can easily adhere to the 3-5cm range at the cut edge. Furthermore, the dust that is kicked up may stick to the cutter surface as it moves toward the negative pressure suction nozzle, causing it to be brought back to the copper foil surface during the next cut. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of the prior art by providing a copper foil slitting device with a dust removal mechanism that has a simple structure and can clean dust from the surface of copper foil.
[0004] The technical solution of this utility model is implemented as follows: A copper foil slitting device with a dust removal mechanism includes a frame, with slitting rollers and several winding rollers for winding the slitting copper foil at the front and rear ends of the frame respectively; several cutters are provided above the slitting rollers, and a first dust extraction hood connected to an external negative pressure is provided on the outer side of each cutter; brushes that cooperate with the two sides of the cutter are symmetrically provided on the inner wall of the first dust extraction hood on both sides of the cutter; an intermediate roller is provided between the slitting rollers and the winding rollers, and a dust removal component for sweeping dust from the upper and lower surfaces of the copper foil is provided between the slitting rollers and the intermediate rollers.

[0017] See Figure 1-5 As shown, this utility model discloses a copper foil slitting device with a dust removal mechanism, comprising a frame 1. The frame 1 has slitting rollers 2 at its front and rear ends, and several winding rollers 3 for winding the slitted copper foil. Several cutters 4 are positioned above the slitting rollers 2, and each cutter 4 has a first dust extraction hood 5 connected to an external negative pressure on its outer side. Brushes 6, matching the surfaces of the cutters 4, are symmetrically arranged on the inner walls of the first dust extraction hoods 5 on both sides of the cutters 4. An intermediate roller 7 is positioned between the slitting rollers 2 and the winding rollers 3, and a dust removal assembly 8 is positioned between the slitting rollers 2 and the intermediate rollers 7 for removing dust from the upper and lower surfaces of the copper foil. By cleaning the cutter surfaces with brushes on the first dust extraction hoods, the brushed dust is drawn away by the first dust extraction hoods, and then the dust removal assembly removes dust from the upper and lower surfaces of the copper foil, effectively reducing dust adhering to the surface of the slitted copper foil and ensuring the quality of the copper foil.
[0018] In this embodiment, the frame 1 is provided with a mounting beam 9, on which a plurality of elongated mounting holes 10 are evenly distributed along the length direction; C-shaped mounting ears 11 are provided on both sides of the first dust extraction hood 5 to cooperate with the mounting beam 9, and mounting holes 12 corresponding to the elongated mounting holes 10 are provided on the C-shaped mounting ears 11. The mounting holes 12 and the elongated mounting holes 10 are connected by fastening screws. With this structure, the installation of the first dust extraction hood can be adjusted according to the actual cutting requirements by adjusting the installation position of the cutter, ensuring that it can cooperate with the cutter.
[0019] In this embodiment, preferably, the brush 6 is mounted on the inner wall of the first dust extraction hood 5 via an adaptive component 13. The adaptive component 13 includes at least two guide rods 13a mounted on the side of the brush 6 away from the cutter 4. A through hole 13b is provided on the side wall of the first dust extraction hood 5 to cooperate with the guide rods 13a. A spring 13c is provided on the guide rods 13a between the inner wall of the first dust extraction hood 5 and the brush 6. When the brush tip rubs against the cutter surface for a long time, the bristles on the brush will wear or bend and deform, causing the bristles to not make close contact with the cutter surface and thus failing to completely remove dust. By setting the adaptive component, the bristles at the brush tip can always remain in close contact with the cutter surface, ensuring effective dust removal from the cutter surface.
[0020] More preferably, the guide rod 13a includes a first round rod 13d located at the center of the side of the brush 6 away from the cutter 4, and two second round rods 13e symmetrically arranged on the brush 6 on both sides of the first round rod 13d; a threaded section 13f is provided on the free end of the first round rod 13d, and an adjusting nut 13g is provided on the threaded section 13f located outside the first dust extraction cover 5, with a washer 13h between the adjusting nut 13g and the outer wall of the first dust extraction cover 5. With this structure, the position of the brush can be adjusted by cooperating with the adjusting nut and the threaded section, which can be used to adapt to cutters of different thicknesses or to change the adhesion between the brush and the cutter surface.
[0021] In this embodiment, preferably, the dust removal assembly 8 includes two sequentially arranged brush rollers 8a, which respectively cooperate with the upper and lower surfaces of the copper foil. A support plate 8b for supporting the copper foil is provided on the frame 1 on the opposite side of each brush roller 8a. A second dust extraction hood 8c connected to an external negative pressure is provided on the outside of each brush roller 8a. A dust-tapping plate 8d, which cooperates with the brushes of the brush roller 8a, is inclinedly provided at the negative pressure port of the second dust extraction hood 8c. When the brush roller rotates to the negative pressure port of the second dust extraction hood, the bristles collide with the dust-tapping plate, knocking off the dust adhering to the bristles. This effectively cleans the dust on the brush roller, preventing the dust from being carried back to the copper foil surface during the next contact, thus effectively improving the efficiency of dust removal. Because the copper foil is thin and has a smooth surface, the brush roller should use soft bristles to avoid the brush being too hard and piercing or scratching the copper foil surface when cleaning dust.
[0022] During operation, the copper foil is conveyed through the slitting roller and cut by the cutter. At the same time, the brush cleans the two sides of the cutter. The cut copper foil is then cleaned by two brush rollers in sequence, with the upper and lower surfaces cleaned respectively. The copper powder removed is extracted through the negative pressure ports on the first and second dust extraction hoods to the external dust recovery and treatment equipment for processing. After the surface dust is cleaned, the copper foil continues to be conveyed through the intermediate roller and then separated and wound up by the slitting rollers.
[0023] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
