Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary manufacturing of coated steel plates, and in particular relates to a stable glue pressing device for coated steel plates. Background Art

[0002] Laminated steel plate gluing is a processing technology that bonds plastic film and metal plate together through high-temperature pressing technology. This technology can make the plastic film firmly adhere to the metal plate. It is widely used in interior and exterior decoration in office buildings, hospitals, hotels, venues, transportation hubs and other fields. In the process of laminated steel plate processing, in order to obtain good adhesion, specific glue is used, such as glue prepared with thermoplastic polyester resin, which can ensure good adhesion between PVC, PET, polyester coating and steel plate, aluminum plate and other materials.

[0003] In the prior art, the glue pressing work of the coated steel plate is usually carried out before the plastic film and the metal plate come into contact, and the glue is applied on the metal plate by a glue dispensing device. After the glue is applied, the plastic film and the metal plate are pressed together by a roller, but the colloid has a certain viscosity, and different colloids have different viscosities. During the pressing, the colloid is unevenly applied and the colloid escapes from the side of the metal plate. When the colloid is unevenly applied, the plastic film and the metal plate will not fit tightly; when the colloid escapes from the side of the metal plate, the colloid that escapes from the side of the coated steel plate needs to be removed later, which has poor adaptability and poor practicality.

[0039] The pressing mechanism 30 includes: a support seat 31, a support plate 32 and a pressing structure 33. The support seat 31 has an open cavity corresponding to the discharge end of the conveying mechanism 10. Two support plates 32 are provided, and the two support plates 32 are arranged at intervals along the second direction and are arranged at intervals above the support seat 31. There are multiple pressing structures 33, and the multiple pressing structures 33 are arranged at intervals along the first direction, which are used to gradually press the colloid between the metal plate to be coated and the plastic film. Each pressing structure 33 is provided with a pressing opening for the metal plate to be coated and the plastic film to pass through, and the height of each pressing opening decreases successively along the conveying direction of the metal plate, and each pressing opening is combined to form a pressing channel.

[0040] The support seat 31 can correspond to the conveying mechanism 10 through the open mouth, and gradually press the colloid between the metal plate to be coated and the plastic film through multiple pressing structures 33. Each pressing structure 33 is provided with a pressing opening for the metal plate to be coated and the plastic film to pass through. The height of each pressing opening decreases successively along the conveying direction of the metal plate, so the colloid can be gradually pressed and applied evenly.

[0041] In some embodiments, the above-mentioned pressing structure 33 can be adopted as follows Figure 1 See the structure shown. Figure 1Each lamination structure 33 includes: a first lamination roller 331, a telescopic structure 332, a second lamination roller 333 and an adjustment component 334. The first lamination roller 331 is rotatably set on the two support plates 32, and the axis of the first lamination roller 331 is set along the second direction. The telescopic structure 332 is used to drive the first lamination roller 331 to move in the vertical direction. The second lamination roller 333 is arranged below the first lamination roller 331 at intervals in the vertical direction, and the rotating shaft of the second lamination roller 333 is rotatably set on the support seat 31, and the rotating axis is set along the second direction.

It can prevent the colloid from overflowing when the colloid is pressed to the edge of the metal plate and the plastic film to ensure the amount of glue applied between the metal plate and the plastic film. The size of each laminating opening can be adjusted by adjusting the thickness of the first sleeve 3341, the second sleeve 3342 and the third sleeve 3343 to achieve a gradual laminating effect.
