Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical equipment, specifically to a dust removal device for sheet-like rolls. Background Technology
[0002] In the production of sheet-like roll materials such as paper, the headbox pours the slurry onto a steel strip, where it is then coated with a specific thickness by a doctor blade. After drying and curing, the slurry is peeled off as a raw sheet and wound into a roll. During the roll material production process, due to factors such as slurry mixing and the production environment, dust particles and other impurities may sometimes adhere to the outer surface of the roll material. If this dust is not removed promptly, it will result in substandard quality of the final product. Utility Model Content
[0003] To address the aforementioned deficiencies in existing technologies, the technical problem this invention aims to solve is how to remove dust particles from sheet-like rolls during production. The specific technical solution provided is as follows:
[0004] A dust removal device for sheet-like roll materials includes a frame, a guide roller assembly, a fixed frame, a lifting mechanism, a support assembly, a dust removal main frame, an air blowing pipe, a bending plate, and a suction pipe. The guide roller assembly is installed at one end of the upper part of the frame. The fixed frame is located away from the guide roller assembly. The lifting mechanism is installed in the fixed frame and drives the support assembly to move up and down. The dust removal main frame is installed above the support assembly. An air blowing pipe with a hollow structure is installed at one end inside the dust removal main frame. The end of the air blowing pipe extends out of the dust removal main frame and has an air blowing port at the bottom. A bending plate is installed at the other end inside the dust removal main frame. The inner cavity of the bending plate is bent to form an air suction chamber. The bottom opening of the air suction chamber forms a dust suction port. A suction pipe is installed on one side of the dust removal main frame and connects to the air suction chamber.
[0005] As a preferred embodiment of this utility model, there are two sets of fixed frame, lifting mechanism and support components. The first set of fixed frame, lifting mechanism and support components is located in front of the main dust removal frame, and the second set of fixed frame, lifting mechanism and support components is located behind the main dust removal frame.
[0006] As a preferred embodiment of this utility model, the lifting mechanism is a cylinder.
[0007] As a preferred embodiment of this utility model, the support assembly includes a support block and a support ring. The support block is inverted T-shaped, and a lifting mechanism is connected to the bottom surface of the support block. The support ring is welded above the middle rod of the support block, and the support ring is fixedly installed on the side of the dust removal main frame.
[0008] In a preferred embodiment of this utility model, the air blowing pipe is connected to a hair dryer, and the dust suction pipe is connected to a vacuum cleaner.
[0009] As a preferred embodiment of this utility model, the width of the air blowing port is smaller than the width of the dust suction port, and the dust suction port is located higher than the air blowing port.
[0010] As a preferred embodiment of this utility model, the air blowing port is tilted to the right and the dust suction port is tilted to the left, with the angle between the central axis of the air blowing port and the central axis of the dust suction port being 45°-70°.
[0011] Beneficial effects: The guide roller assembly guides the roll material below the main dust removal frame. The lifting mechanism drives the main dust removal frame to descend and approach the roll material. Air is blown out from the air outlet at the bottom of the air blowing pipe onto the roll material. The dust particles on the surface of the roll material are blown away and loosened. The dust is sucked into the suction chamber through the dust suction port and then output to the outside through the dust suction pipe. The dust removal method of blowing first and then sucking can effectively remove dust and impurities from the surface of the roll material, which helps to ensure product quality and meet production needs.
