Description

Technical Field

[0001] This utility model relates to the field of color-coated steel sheet production technology, and in particular to a color-coated steel sheet roller coating device. Background Technology

[0002] Pre-coated steel sheets are a widely used building material. They are made from metal coils such as cold-rolled steel sheets, hot-dip galvanized steel sheets, aluminized steel sheets, high-aluminum alloy steel sheets, or stainless steel sheets, with organic coatings applied to their surfaces. Existing roller coating equipment for pre-mixing pre-stirred pre-coated steel sheets typically involves pre-stirring the coating material before adding it to the hopper, where it is picked up by a roller for application. However, during continuous production, the coating material tends to settle or form a skin due to prolonged standing in the hopper, leading to uneven coating application in certain areas of the pre-coated steel sheet. This affects the coating quality and reduces the yield rate of the finished product.

[0003] Therefore, there is an urgent need for a color-coated steel sheet roller coating device that can stir the paint in the material box during the color-coated steel sheet coating process to avoid paint sedimentation and skin formation, thereby improving the coating effect of the color-coated steel sheet. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a roller coating device for color-coated steel sheets.

[0005] This utility model is achieved through the following technical solution: a color-coated steel plate roller coating device is provided, including a material box for holding paint, a material taking roller that is rotatably connected to the inner wall of the material box at both ends by rotating shafts, and a drive motor for driving the material taking roller to rotate; a set of stirring mechanisms are respectively installed on the rotating shafts at both ends of the material taking roller, and each set of stirring mechanisms includes a first swing rod and a second swing rod, and a connecting piece that drives the first swing rod and the second swing rod to swing left and right.

[0006] Preferably, the connector includes a first connecting rod fixed to the rotation shaft and a second connecting rod with one end hinged to the first connecting rod, and the other end of the second connecting rod hinged to the top of the first swing rod.

[0007] Preferably, the upper parts of the first swing rod and the second swing rod are rotatably connected to the inner wall of the hopper via connecting shafts, and the top ends of the first swing rod and the second swing rod are connected via connecting arms.

[0008] Preferably, the two ends of the connecting arm are hinged to the first swing rod and the second swing rod respectively, and the hinges between the first swing rod and the second connecting rod and the first swing rod and the connecting arm are coaxial hinges.

[0009] Preferably, a first stirring plate is connected between the two first swing rods of the two sets of stirring mechanisms, and a second stirring plate is connected between the two second swing rods of the two sets of stirring mechanisms. The two first swing rods swing synchronously, driving the first stirring plate to stir the coating, and the two second swing rods swing synchronously, driving the second stirring plate to stir the coating, thereby achieving agitation of the coating and preventing the coating from settling or forming a skin.

[0010] Preferably, a coating roller for applying the coating on the coating roller to the substrate surface and a guide roller for supporting and guiding the substrate are provided above the coating roller, and the output shaft of the drive motor is connected to the rotation shaft of one end of the coating roller.

[0011] The beneficial effects of this utility model are as follows:

[0012] The rotating shaft of this invention drives the first and second swing rods to swing via the first and second connecting rods, causing the first and second stirring plates to agitate the coating. This effectively prevents coating sedimentation or skin formation, ensures uniform coating of the substrate, improves the coating effect of the color steel plate, and enhances product quality.

[0018] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0019] like Figure 1-3 As shown, this utility model includes a material box 1 for holding paint, a material taking roller 3 whose two ends are rotatably connected to the inner wall of the material box 1 via rotating shafts 2, and a drive motor for driving the material taking roller 3 to rotate. A set of stirring mechanisms are respectively installed on the rotating shafts 2 at both ends of the material taking roller 3.

[0020] Each mixing mechanism includes a first swing rod 4 and a second swing rod 12, as well as a connecting member that drives the first and second swing rods 4 and 12 to swing left and right. The connecting member includes a first connecting rod 5 fixed to the rotating shaft 2 and a second connecting rod 6 with one end hinged to the first connecting rod 5. The other end of the second connecting rod 6 is hinged to the top of the first swing rod 4. The upper parts of the first swing rod 4 and the second swing rod 12 are rotatably connected to the inner wall of the material box 1 through connecting shafts 7, respectively. The tops of the first swing rod 4 and the second swing rod 12 are connected through a connecting arm 8. The two ends of the connecting arm 8 are hinged to the first swing rod 4 and the second swing rod 12, respectively. The hinges between the first swing rod 4 and the second connecting rod 6, and between the first swing rod 4 and the connecting arm 8, are coaxial hinges.

[0021] The two first swing rods 4 of the two sets of stirring mechanisms are connected to the first stirring plate 9, and the two second swing rods 12 of the two sets of stirring mechanisms are connected to the second stirring plate 13. The two first swing rods 4 swing synchronously to drive the first stirring plate 9 to stir in the coating, and the two second swing rods 12 swing synchronously to drive the second stirring plate 13 to stir in the coating, thereby realizing the stirring of the coating and avoiding the coating from settling or forming a skin.

[0022] Above the feed roller 3, a paint roller 10 is provided for applying the paint on the feed roller 3 to the surface of the substrate, and a guide roller 11 is provided for supporting and guiding the substrate. The output shaft of the drive motor is connected to the rotating shaft 2 at one end of the feed roller 3.

[0023] The drive motor rotates the material-collecting roller 3 via the rotating shaft 2. As the material-collecting roller 3 rotates, it picks up paint from the material box 1. The paint roller 10 rotates under the drive of the material-collecting roller 3 and applies the paint on the material-collecting roller 3 to the surface of the substrate. The rotation of the rotating shaft 2 drives the first swing rod 4 and the second swing rod 12 to swing via the first connecting rod 5 and the second connecting rod 6. This causes the first stirring plate 9 and the second stirring plate 13 to stir the paint, preventing paint sedimentation or skin formation, ensuring uniform coating of the substrate, improving the coating effect of the color steel plate, and improving product quality.
