Description

Technical Field

[0001] The utility model relates to the technical field of aluminum foil production equipment, in particular to an aluminum powder adsorption device at an inlet of an aluminum foil slitting machine. Background Art

[0002] Aluminum foil slitting machines are commonly used in aluminum foil production. They use blades on a knife holder located at the feed inlet to slit the continuously fed aluminum foil into finished aluminum foil rolls of specified specifications. However, during the high-speed slitting process, aluminum powder will be generated on both sides of the blade. When the finished aluminum foil roll is subsequently curled, it will be rolled into the finished aluminum foil roll, thus affecting product quality.

[0003] Aluminum foil has a variety of specifications for different industrial applications, and its width can range from a few millimeters (such as extremely narrow aluminum foil used for precision packaging of electronic components) to several meters (such as wide aluminum foil used for large industrial packaging or building insulation). When the aluminum foil slitting machine performs slitting operations, it needs to handle aluminum foil raw materials of different widths. If the suction hood cannot adapt to this diverse variation in aluminum foil width, it will result in uneven coverage when slitting aluminum foil of different widths. For example, when slitting narrow aluminum foil, an overly wide fixed suction hood may cause unnecessary waste of suction and may lack suction in the edge area; while when slitting wide aluminum foil, a narrow suction hood cannot completely cover the area where aluminum powder is generated at the inlet. Utility Model Content

[0004] The purpose of the utility model is to solve the problems in the background technology and to propose an aluminum powder adsorption device at the inlet of an aluminum foil slitting machine.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A device for adsorbing aluminum powder at the inlet of an aluminum foil slitting machine comprises an air suction hood and a telescopic mechanism, wherein the telescopic mechanism comprises a first motor fixedly mounted on the top of the air suction hood, the first motor being rotatably connected to a screw with a different direction of thread through a gear transmission assembly, the two ends of the screw with a different direction of thread being sleeved and threadedly connected to a fixed plate, the bottoms of the two fixed plates being fixedly connected to the telescopic hood, grooves being provided on both sides of the air suction hood, the telescopic hood being slidably connected to the air suction hood.

[0007] Preferably, the top of the suction hood is fixedly connected to an L-shaped rod, the L-shaped rod passes through and is threadedly connected to a threaded rod, the top of the threaded rod is fixedly connected to a second motor, the second motor is fixedly connected to a fixing frame through two symmetrical fixing rods, and the bottom of the fixing frame is fixedly connected to a base.

[0008] Preferably, a ventilation duct is fixedly connected to the top of the air hood, and a dustproof processor is provided at one end of the ventilation duct away from the air hood.

[0009] Preferably, the gear transmission assembly includes a first gear fixedly connected to the output end of the first motor, a second gear is sleeved on the middle end of the counter-rotating screw, and the first gear is meshed with the second gear.

[0010] Preferably, a sliding rod is fixedly connected to the top inner wall of the fixing frame, the sliding rod penetrates and is slidably connected to the L-shaped rod, and the sliding rod is fixedly connected to the top of the base.

[0011] Preferably, the threaded rod passes through and is rotatably connected to the top of the fixing frame, and is rotatably connected to the top of the base.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. This utility model utilizes a telescopic mechanism to adjust according to the actual width of the aluminum foil, ensuring that the coverage width of the suction hood matches the width of the foil. This allows the suction hood to cover the area where aluminum powder is generated, regardless of whether the foil is narrow or wide, at the entrance of the foil slitting machine. This minimizes the possibility of aluminum powder escaping into the surrounding environment. For example, when slitting narrow foil, the suction hood can be retracted to concentrate the negative pressure in a smaller area above the foil, effectively capturing aluminum powder. When slitting wide foil, the suction hood is extended to accommodate the wide foil, creating a uniform negative pressure across the entire width of the foil, thereby drawing in the generated aluminum powder.

[0014] 2. The utility model can adapt to the slitting of aluminum foils of different thicknesses by arranging an L-shaped rod, a threaded rod, a second motor and a fixed frame, and avoids the situation where the suction hood is too high or too low, resulting in poor capture effect of floating aluminum powder. The height can be adjusted according to the specific structure of the slitting machine, so as to adapt to different models of slitting machines, which increases the versatility of the adsorption device.
