Description

Technical Field

[0001] This utility model relates to an electric spraying roller capable of spraying paint onto interior and exterior walls and roofs, and belongs to the field of electric spraying roller manufacturing. Background Technology

[0002] The applicant's prior patent CN203695352U, entitled "Manual Sprayer," includes a housing, a rotating core with a spring-loaded spring installed inside the housing, a crank handle that drives the rotating core to rotate, a handle located on the outside of the housing, and a support rod; the handle has a mounting hole, and one end of the support rod is located inside the mounting hole. Using this manual sprayer, high-altitude spraying operations can be performed conveniently and easily, reducing the labor intensity of operators and effectively improving spraying quality. Summary of the Invention

[0003] Design objective: Based on all prior patents of the applicant, to design an electric spraying roller capable of spraying paint onto interior and exterior walls and roof surfaces by electrically driving the main gear in the rotating core.

[0004] Design Scheme: To achieve the above design objectives, this utility model features the following structural design: 1. The use of a motor-driven roller rotor is one of the technical characteristics of this utility model. The purpose of this design is that the roller serves as both the container for the paint and the carrier before the rotating core sprays the paint. Therefore, when the paint is inside the roller, its weight increases. Manually operating the rotating core at high speed to spray paint is not only very strenuous, but also results in uneven paint distribution due to varying hand crank speeds, leading to uneven coating thickness on walls or roofs and directly affecting the coating quality. This utility model replaces the manual power spraying in the background technology with motor-driven spraying. Since the motor's set speed and output power are constant, using a motor-driven rotating core to spray paint not only saves labor, effort, and time, but also ensures consistent spraying speed and amount. Consequently, the coating thickness on walls and roofs is relatively consistent, with strong adhesion and a good visual effect. 2. The matching design of the main toothed plate and the baffle plate located inside the open roller with damped elastic forced passage is the second technical feature of this utility model. The purpose of this design is that: the main toothed plate is a material with a certain degree of forced elasticity, and it is the direct sprayer that sprays the paint out of the roller. This utility model uses the damped elastic forced passage matching of the main toothed plate and the baffle plate, which is like the main toothed plate undergoing elastic deformation under the action of the baffle plate. When the elastic deformation degree of the main toothed plate (the height decreases when the curvature is formed) can pass through the baffle plate, the paint adhering to the main toothed plate is reflected out under the action of the elastic deformation force. The greater the rebound force, the farther the paint is reflected. When the distance is set, the greater the rebound force, the better the adhesion of the reflected paint. 3. The design of the auxiliary toothed plate attached to the main toothed plate from the root (which can be set in the upper middle, middle, or lower middle part of the main toothed plate according to the rebound force requirements of the main toothed plate) is the third technical feature of this utility model. The purpose of this design is as follows: Since the strength of the secondary toothed plate is greater than that of the primary toothed plate, and the secondary toothed plate does not undergo elastic deformation along with the primary toothed plate, when the primary toothed plate with the secondary toothed plate attached forcibly passes through the baffle, the secondary toothed plate dampens the elastic deformation of the lower part of the primary toothed plate. Therefore, the force required for the elastic deformation of the primary toothed plate when forcibly passing through the baffle is increased, that is, the elasticity is enhanced. The rebound generated when passing through the damping baffle is greater, and the force that the paint attached to the primary toothed plate reflects off it under the action of the stored force of elastic deformation is greater, and the distance of paint reflection is farther. When the distance is set, the adhesion of the paint reflected onto the wall and roof surface is better. 4. The adjustable baffle angle is the fourth technical feature of this utility model.The purpose of this design is that, since the roller of this application is equipped with a baffle for adjusting the magnitude of the elastic deformation force of the main tooth plate, when the contact area between the baffle and the main tooth plate increases, the rebound force of the main tooth plate increases; when the contact area between the baffle and the main tooth plate decreases, the rebound force of the main tooth plate decreases. That is, by changing the angle of the baffle, the magnitude of the elastic rebound force of the main tooth plate can be changed.

[0005] Technical Solution: An electric spraying roller includes an open roller and a rotating core installed inside the open roller. The rotating core consists of a hollow rotating body, auxiliary toothed plates, and main toothed plates. The main toothed plates are fixedly spaced circumferentially on the hollow rotating body, and the auxiliary toothed plates are attached to the lower or lower-middle part of the main toothed plates. The two ends of the hollow rotating body are respectively in rotational engagement with the rotating core mounting arms located on both sides of the open roller. A motor is mounted inside the hollow rotating body and drives the rotating core to rotate. The relatively converging parts of the rotating core mounting arms located on both sides of the open roller are battery sockets. A rechargeable battery is plugged into the battery socket. The power output terminal of the battery socket controls whether the motor works through a switch. An arc-shaped switch handle is located on the non-opening part of the open roller. A switch is provided on the arc-shaped switch handle. A baffle is located inside the open roller and is in damped elastic pass-through engagement with the main toothed plates in the rotating core.

[0006] Compared with the prior art, this utility model has two advantages: First, when using a motor-driven rotating core to spray paint, it not only saves labor, effort, and time, but also ensures consistent spraying speed and amount, resulting in a relatively uniform coating thickness on walls and roofs. This leads to strong adhesion and a superior visual effect. Second, the matching design of the main toothed blade and the baffle plate located inside the open roller, which provides damped elastic forced passage, allows the magnitude of the main toothed blade's rebound force to be adjusted by changing the downward or upward movement of the baffle plate, based on the required rebound force. When the elastic deformation of the main toothed blade reaches a point where it can pass through the baffle plate, the paint adhering to the main toothed blade accumulates elastic deformation. Under the action of force, the paint on it is reflected outward. The greater the rebound force, the farther the paint is reflected. When the distance is set, the adhesion of the reflected paint is better. Third, the design of the auxiliary toothed plate attached to the main toothed plate limits the elastic force of the main toothed plate from the root to the middle or lower part. Therefore, when the upper part of the main toothed plate is subjected to force, the middle and lower part will not rebound and deform. The rebound force of the main toothed plate is concentrated in the upper or upper middle part of the main toothed plate for reflecting the sprayed paint. This not only has a good reflective spraying effect on the paint, but also strong adhesion of the sprayed paint. Fourth, the design of the baffle blocking distance can be adjusted to change the magnitude of the elastic rebound force of the main toothed plate. Attached Figure Description

The engagement method can be various and is existing technology, which will not be described here.

[0013] Motor 4 is a waterproof motor, and waterproof motors are existing technology, so they will not be described here. The waterproof motor is mounted in the hollow rotating body, and motor 4 drives the rotating core 2 to rotate. The rotating core 2 is composed of a hollow rotating body 23, a secondary toothed plate 22, and a main toothed plate 21. The main toothed plate 21 is fixed to the hollow rotating body 23 at intervals along its circumference. The secondary toothed plate 22 is attached to the lower part of the main toothed plate 21. The secondary toothed plate 22 is attached to the main toothed plate 21 from the root of the main toothed plate 21 upwards to the middle, or lower, or upper middle part. The specific assembly method and process are existing technology and will not be described here.

[0014] The retractable portions of the rotating core mounting arms 3 located on both sides of the open roller are battery connectors 5. Battery connectors 5 are known technology and have been publicly used in products such as cordless hand drills. The rechargeable battery 6 is plugged into the battery connector 5 for easy plugging in after charging and unplugging after depletion of power. This is existing known technology and will not be described in detail here.

[0015] The power output terminal of the battery socket 5 is connected to the motor 4 via the switch 8 and lead wires. The power supply method and connection system are existing technologies and will not be described here.

[0016] The arc-shaped switch handle 7 is located (installed) on the non-opening part of the open roller 1 and the arc-shaped switch handle 7 is equipped with a switch 8. The switch 8 is purchased externally and controls whether the motor 4 works through the power lead. The baffle 10 is located inside the open roller and the baffle and the main tooth 21 in the rotating core 2 are in a damped elastic pass-through fit.

[0017] An auxiliary handle 9 is provided on the open roller 1 located above the arc-shaped switch handle 7. The auxiliary handle 9 works in conjunction with the arc-shaped switch handle 7 to complete the spraying of the wall or roof surface.

[0018] The motor housing 41 drives the rotating core 2 to rotate via the driving rotor 42, but in practical applications, it is not limited to this structure.

[0019] The baffle plate 10 has two ends that are rotatably engaged with the two sides of the drum, and one end of the baffle plate 10 is connected to one end of the pull rod 11 through the butterfly nut 13. The other end of the pull rod 11 is engaged with the dividing plate 12 located on the side of the drum. That is, the pull rod 11 can drive the baffle plate 10 to rotate. When the baffle plate 10 rotates downward, the contact area between the baffle plate 10 and the main toothed plate 21 increases, and the rebound force generated by the main toothed plate 21 increases. Conversely, when the baffle plate 10 rotates upward, the contact area between the baffle plate 10 and the main toothed plate 21 decreases, and the rebound force generated by the main toothed plate 21 decreases.
