[0002] In the field of laminated foil roll cutting, the dust removal mechanism of the slitting machine is a key component to ensure the cleanliness of the material surface. Traditional dust removal solutions mostly adopt a fixed air knife structure, which has certain shortcomings: First, the position adjustment is limited: conventional air knives are fastened to the slitting machine frame with bolts, and their position cannot be adjusted during the tape threading operation; operators need to repeatedly remove and remove bolts to adjust the position, which increases the time for each tape threading operation by about 40%, seriously affecting the equipment utilization efficiency.

[0003] Secondly, there is a limitation in functionality: existing air knives are only equipped with a single-stage dust removal system. Although they can remove non-metallic particles larger than 80μm, they are completely ineffective against ferromagnetic debris (commonly 30-150μm in diameter) generated during processing. According to industry statistics, micro-short circuit defects caused by the failure to remove iron impurities account for 12-15% of product defects.

[0004] Therefore, there is an urgent need to develop new dust removal mechanisms that combine intelligent adjustment and composite cleaning functions. Utility Model Content

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0020] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0021] Example: like Figures 1 to 5 As shown, this application provides a slitting machine air knife dust removal mechanism, including: an air knife dust removal assembly 10; cylinder connecting plates 20 symmetrically installed at both ends of the air knife dust removal assembly 10; an adjusting cylinder 30 connected between the output end and the cylinder connecting plate 20; and a roller 40 provided at the upper end of the air knife dust removal assembly 10; the air knife dust removal assembly 10 includes a dust collection cylinder 11, an air duct 12 located at the bottom of the dust collection cylinder 11 and communicating with its interior, a positive air chamber 13 and a magnet 19 installed on the outside of the dust collection cylinder 11, a positive air cover plate 131 provided on the outside of the positive air chamber 13, an air valve 14 provided on the outside of the positive air chamber 13, a positive pressure air hole 16 opened in the middle of the positive air cover plate 131, a negative pressure cover plate 17 provided on the top of the dust collection cylinder 11, and a negative pressure air hole 18 opened in the middle of the negative pressure cover plate 17; According to the appendix Figure 5 It can be seen that S is a slitting machine and E is a foil strip. There are two sets of adjusting cylinders 30, and the outer side of the adjusting cylinders 30 is provided with mounting parts. The adjusting cylinders 30 are installed on the slitting machine S through the mounting parts. The roller 40 is also installed on the slitting machine S. Before the roller 40 and the air knife dust removal assembly 10 are used, the foil strip E is threaded through the middle of the two, and the air knife dust removal assembly 10 can remove dust from the foil strip E.

[0022] By adopting the above technical solutions, the limitations of existing dust removal air knife position adjustment can be solved through the setting of the air knife dust removal component 10 and the adjusting cylinder 30: conventional air knives are fastened to the slitting machine frame with bolts, and their position cannot be adjusted during tape threading operations; operators need to repeatedly disassemble and reassemble the bolts to adjust the position, increasing the time for each tape threading operation by about 40%, which seriously affects the equipment utilization efficiency; the single-function defect: existing air knives are only equipped with a single-stage dust removal system, which can remove non-metallic particles larger than 80μm, but is completely ineffective against ferromagnetic debris (common particle size 30-150μm) generated during processing. According to industry statistics, the problem of micro-short circuit defects in products caused by unremoved iron impurities accounts for 12-15%.

[0023] It should be noted that during the dust removal process of the foil strip E, firstly, the output ends of the two sets of adjusting cylinders 30 are controlled to drive the cylinder connecting plate 20 and the air knife dust removal assembly 10 to reset, thereby increasing the gap between the air knife dust removal assembly 10 and the roller 40, making it easier to pass the foil strip E through the middle of the air knife dust removal assembly 10 and the roller 40. Then, the two sets of adjusting cylinders 30 are used to drive the cylinder connecting plate 20 and the air knife dust removal assembly 10 to reset, maintaining a certain distance from the foil strip E, and the external air supply pipe and air valve are used to control the dust removal process. The door 14 is connected to the positive air chamber 13, which is then filled with air. The air then enters the air duct and is finally blown out through the positive pressure air hole 16 to remove dust from one side of the foil strip E. At the same time, the air duct 12 is connected to the input end of the external air extraction equipment to perform a suction operation, so that the blown-off dust enters the dust collection cylinder 11 through the negative pressure air hole 18. Finally, the magnet 19 is used to perform a final iron impurity removal operation on the outside of the foil strip E to reduce the occurrence of micro short circuit defects in the foil strip E in the future.

[0024] In an optional embodiment, a protective pad 15 is provided on one side edge of the upper end of the positive air cover plate 131; the protective pad 15 is a sponge pad. By providing the protective pad 15, the foil strip E can avoid friction with one side edge of the positive air cover plate 131 and avoid wear during the conveying process along the roller 40.

[0025] In an optional embodiment, the cylinder connecting plates 20 are in two sets and symmetrically distributed, and the cylinder connecting plates 20 are connected to the dust collection cylinder 11 by bolts. The cylinder connecting plates 20 have a "T" shaped structure, according to the appendix. Figure 2 It can be seen that a bonding block is installed at one end of the cylinder connecting plate 20, which is connected to the dust collection cylinder 11 by bolts to ensure the stability between the cylinder connecting plate 20 and the dust collection cylinder 11. Then, the end of the cylinder connecting plate 20 away from the bonding block is connected to the output end of the adjusting cylinder 30 by bolts to ensure that the adjusting cylinder 30 can normally drive the cylinder connecting plate 20 and the air knife dust removal assembly 10 to rise and fall.

[0026] In an optional embodiment, the dust collection cylinder 11 is connected to the air duct 12, and the end of the air duct 12 is provided with a hose clamp. The end of the air duct 12 is connected to the input end of the external air extraction device. The hose clamp connects and fixes the end of the air duct 12 to the input end of the external air extraction device, so that the negative pressure air hole 18 can generate negative pressure to provide a basis for drawing dust into the interior of the dust collection cylinder 11.

[0027] In an optional embodiment, a duct is provided in the middle of the positive air chamber 13, which is connected to the protective pad 15. One end of the air valve 14 is connected to the duct, and the other end of the air valve 14 is connected to the external air supply pipe, so as to ensure that the gas can enter the duct through the air valve 14 and then be discharged through the positive pressure air hole 16. Since the positive pressure air hole 16 is a strip structure, it can uniformly perform dust removal operation on the outer side of the foil strip E.

[0028] In an optional embodiment, the negative pressure cover plate 17 and the dust collection cylinder 11 are connected by bolts, which can ensure that the negative pressure cover plate 17 can be disassembled and installed normally. If blockage occurs later, it can be disassembled and cleaned in time. The negative pressure air hole 18 penetrates the negative pressure cover plate 17 and is connected to the inside of the dust collection cylinder 11, which can ensure that dust can be sucked into the inside of the dust collection cylinder 11 for dust removal.

[0029] In an optional embodiment, angle irons are provided at both ends of the magnet 19, and the angle irons are connected to the dust collection cylinder 11 by bolts. This allows the magnet 19 to be installed and removed from one side of the dust collection cylinder 11. The included angle between the magnet 19 and the dust collection cylinder 11 is greater than 90 degrees, ensuring that the foil strip E does not come into contact with the magnet 19 during the rotation of the roller 40. This allows for the adsorption and cleaning of metal debris on the outside of the foil strip E. The magnet 19 is an N52 neodymium iron boron magnet, fixed to the side wall of the dust collection cylinder 11 by ∠30×3 angle irons (150mm spacing). The magnet installation angle is designed to be 115°±1°, forming a 2.5mm non-contact gap with the roller 40.

[0030] This configuration generates a 0.5T gradient magnetic field on the surface of foil strip E, which can adsorb iron filings with a particle size ≥50μm, while avoiding contact wear of the foil (relative speed ≤0.01m / s), and the metal impurity removal rate is ≥98%.
