Description

Technical Field

[0001] This invention relates to the field of aluminum rod processing technology, and in particular to an online dust removal device for the surface of aluminum rods. Background Technology

[0002] With the rapid development of the aluminum market, increasingly stringent requirements are being placed on the quality, mechanical properties, dimensional tolerances, and appearance of aluminum products. Therefore, strict control of production processes and improved product quality are necessary to meet market demands. Currently, aluminum rods are mainly transported by train and truck in open-air conditions, involving various processes such as changing vehicles, handling, and waiting, inevitably resulting in dust, oil, and other impurities adhering to the surface of the aluminum rods. During production, companies typically directly immerse the aluminum rods in heating furnaces for heating. These impurities then continue to accumulate on the molds and profiles during production, affecting output quality and product qualification rates. Therefore, cleaning of the aluminum rod surfaces is essential.

[0003] For example, patent CN110788044A discloses an aluminum rod cleaning device, which includes a frame, a cleaning mechanism mounted on the frame, a drive motor mounted above the frame, and an aluminum rod passing through the cleaning mechanism. The cleaning mechanism includes a roller, a pulley at one end of the roller, a disc at the other end of the roller, a counterweight and a fixing rod mounted on the disc, a cleaning brush hinged to the counterweight, and a spring fixed to the fixing rod by screws. By installing the cleaning mechanism, which consists of a roller, pulley, disc, counterweight, fixing rod, cleaning brush, and spring, inside the frame, and using the centrifugal force generated by the rotation of the roller under the action of the drive motor, the cleaning brush presses tightly against the aluminum rod and rotates continuously, effectively removing oxides from the surface of the aluminum rod. However, this device is not suitable for online cleaning. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an online dust removal device for aluminum rod surfaces, which enables online processing and improves product production efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: The online cleaning device for aluminum rod surfaces includes a frame, on which are mounted rollers that carry the aluminum rods in a straight line and a cleaning mechanism for cleaning the surface of the aluminum rods. The lower part of the frame is provided with a drive structure for driving the rollers. The cleaning mechanism includes a rotating frame, with an inner area for the aluminum rods to pass through, and a wire brush on the inner side of the rotating frame.

[0006] Further or preferred: The drive structure includes a drive motor, a chain, and a drive roller. The end of the drive roller is provided with a driven gear, and the drive motor is provided with a driving gear. The driving gear and the driven gear are connected by a chain.

[0007] The rotating frame is a ring frame, with a toothed ring on the outer edge of the ring frame. A servo motor is mounted on the frame, and a drive gear that meshes with the toothed ring is mounted on the servo motor.

[0008] The frame is equipped with an annular spray structure in front of the dust removal mechanism, through which the aluminum rod passes.

[0009] It also includes a controller, and the drive motor and servo motor are all connected to the controller.

[0010] The ring frame is provided with a slot, one end of which is open, and the brush body of the wire brush can be inserted into the slot. The end of the slot and the brush body are connected by fasteners.

[0011] The wire brushes are arranged in a circumferential manner.

[0012] A negative pressure dust collection structure for dust collection is provided on the frame behind the dust removal mechanism.

[0013] The negative pressure dust collection structure is a ring-shaped box with a hollow area in the center for the aluminum rod to pass through, and a dust collection port on the side of the ring-shaped box facing the dust removal structure.

[0014] The inner side of the annular box is provided with an adsorption port corresponding to the hollow area.

[0015] Compared with the prior art, the present invention has the following advantages: The online cleaning device for aluminum rods has a reasonable structural design. Before entering the heating furnace, the aluminum rods first pass through this cleaning device. The aluminum rods move in a straight line back and forth, while the cleaning mechanism rotates. The continuous friction between the steel wire brush inside the cleaning mechanism and the surface of the aluminum rod removes dust and debris. The cleaned dust and debris are collected in the lower collection device to avoid environmental pollution. At the same time, the cleaning mechanism and the aluminum rod drive are synchronously linked, further reducing energy consumption.
