Description

Technical Field

[0001] The utility model relates to the field of primer painting, in particular to a primer painting device. Background Art

[0002] Primer is the first layer of architectural coatings, which is used to improve the adhesion of the topcoat, increase the fullness of the topcoat, enhance alkali resistance, provide anti-corrosion functions, etc. At the same time, it can ensure that the topcoat can be evenly absorbed so that the paint can play the best effect. As for wall painting or painting, most of the current construction methods are still manual operations, which are inefficient. When facing high walls, workers need to climb up ladders to work. After painting an area, they need to get off the ladder and move the ladder to continue painting, which is very inconvenient and dangerous.

[0003] Therefore, in order to solve the deficiencies in the prior art, a primer painting device with a simple structure needs to be designed. Utility Model Content

[0004] The utility model provides a primer painting device to solve the problems of the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a primer brushing device comprises: a bracket, a lifting assembly and a brush roller, the lifting assembly is symmetrically arranged at the upper end of the bracket, the lifting assembly comprises a motor, a fixed rod, a lifting rod 1, a lifting rod 2 and a connecting plate, the lifting rod 1 is slidably arranged on the inner side of the fixed rod, the lifting rod 2 is arranged on the inner side of the lifting rod 1, the connecting plate is fixed to the upper end of the lifting rod 2, the brush roller is rotatably arranged between the two groups of connecting plates, the upper end of the fixed rod is rotatably provided with a pulley 1, the lower end of the fixed rod is provided with a fixed wheel 1, the upper end of the lifting rod 1 is rotatably provided with a pulley 2, the lower end of the lifting rod is provided with a fixed wheel 2, the lower end of the lifting rod 2 is provided with a fixed wheel 3, the motor crosses pulley 1 through a wire 1 and is connected to the fixed wheel 2, the fixed wheel 1 crosses pulley 2 through a wire 2 and is connected to the fixed wheel 3.

[0006] As a further improvement, the fixed rod, the lifting rod one and the lifting rod two are provided with sliding grooves on the right side, and the lifting rod one and the lifting rod two are provided with sliding blocks matching the sliding grooves on the left side.

[0007] As a further improvement, universal wheels are provided at the bottom of the bracket.

[0008] As a further improvement, a push handle is provided on the right side of the bracket.

[0009] Compared with the prior art, the primer coating device of the utility model has the following beneficial effects:

[0010] After the brush roller is dipped in primer, the motor drives the winding wire 1. Since one end of the wire 1 is fixedly connected to the fixed wheel 1, the lifting rod 1 moves upward while the pulley 1 rotates. The lifting rod 1 moves upward and drives the pulley 2 to move upward. Since one end of the wire 2 is fixed to the fixed wheel 1 and the other end is fixed to the fixed wheel 3, the lifting rod 2 moves upward, and the brush roller located between the connecting plates is lifted in multiple stages. No manual operation is required, which is convenient for painting at different heights of the wall and reduces the labor intensity. In addition, the motor drives multiple lifting rods to lift the lifting rods through pulleys and fixed wheels at different positions, which has a simple structure, low cost, and easy maintenance.
