Description

Technical Field

[0001] The utility model belongs to the technical field of guide rollers, and in particular relates to a guide roller structure for producing aluminum-plastic panels. Background Art

[0002] Aluminum-plastic composite panels (also known as aluminum-plastic panels) possess unique properties and are suitable for building exteriors, curtain wall panels, renovation of older buildings, interior wall and ceiling decoration, advertising signs, display stands, and purification and dust control projects. They are a new type of building decoration material. Aluminum-plastic panels are composed of multiple layers: the upper and lower layers are high-purity aluminum alloy sheets, with a non-toxic low-density polyethylene (PE) core sheet in the middle. A protective film is applied to the front surface. For exterior applications, the front surface of the aluminum-plastic panel is coated with a fluorocarbon resin (PVDF) coating; for interior applications, a non-fluorocarbon resin coating can be used.

[0003] During the production of aluminum-plastic panels, the PE core sheet must be directly bonded to the aluminum alloy face sheet to ensure a smooth surface, ensuring the product's aesthetics and the convenience of later processing. This results in the PE core sheet being easily slipped or deflected during conveying due to its high conveying speed and smooth surface, leading to production interruptions and impacting production efficiency. To ensure the efficient conveying of the PE core sheet, a guide roller structure with fixed anti-slip ridges is generally used. However, the anti-slip ridges are generally fixedly connected to the guide roller sleeves, requiring the entire guide roller to be replaced after wear, resulting in relatively high costs. Furthermore, the anti-slip ridges have a large contact area with the sheet material, which can cause scratches or wear on the sheet material surface over time. Therefore, the present utility model proposes a guide roller structure for aluminum-plastic panel production that prevents the PE core sheet from sliding during conveying, ensuring its stable forward movement, while dispersing pressure and reducing the direct contact area with the PE core sheet, thereby reducing the risk of damage to the core sheet. Furthermore, the anti-slip sleeves can be easily replaced after wear, thereby reducing production and maintenance costs.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a guide roller structure for aluminum-plastic plate production, comprising a central shaft and an end cover, an inner roller sleeve is sleeved on the outer side of the central shaft body, an anti-slip sleeve is sleeved on the outer side of the inner roller sleeve, an outer roller sleeve is sleeved on the outer side of the anti-slip sleeve, the outer surface of the anti-slip sleeve is evenly provided with anti-slip bumps, and the surface of the outer roller sleeve is evenly provided with bump grooves, bearing seats are installed at both ends of the inner roller sleeve, the inner wall of the end of the outer roller sleeve abuts on the bearing seat, the end cover is installed at both ends of the outer roller sleeve, the end of the outer roller sleeve, the end cover and the bearing seat are fastened by screws, a rolling bearing is nested between the bearing seat and the central shaft body, and a sealing gasket is installed on one side of the bearing seat of the inner roller sleeve.

[0006] As a preferred technical solution of the present invention, there is a one-to-one correspondence between the convex point grooves and the anti-slip convex points, and the anti-slip convex points pass through the convex point grooves.

[0007] As a preferred technical solution of the present invention, the outer roller sleeve includes an upper roller sleeve and a lower roller sleeve, and the upper roller sleeve and the lower roller sleeve are connected to form a cylindrical structure.

[0008] As a preferred technical solution of the present invention, the anti-slip sleeve and the anti-slip protrusions are an integrally formed structure, and are both made of rubber.

[0009] As a preferred technical solution of the present invention, the outer roller sleeve and the inner roller sleeve are both made of stainless steel.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] During the production of aluminum-plastic panels, this utility model provides rubber bumps on the guide roller surface to increase friction between the guide roller and the PE core sheet, preventing the PE core sheet from sliding during transportation and ensuring its stable advancement. The rubber bumps also disperse pressure, reducing direct contact with the PE core sheet, thereby reducing the risk of damage to the core sheet. Furthermore, stainless steel outer roller sleeves are provided at the base of the bottom rubber bumps to strengthen the base support of the rubber bumps, making them less susceptible to deformation or damage when subjected to transportation pressure. These sleeves are also easily replaced after long-term wear and tear, thereby ensuring production efficiency and reducing maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS
