Description

Technical Field

[0001] This invention belongs to the field of building decoration equipment, specifically referring to a reciprocating building decoration wall painting device. Background Technology

[0002] Wall painting is an essential process in most building renovations. Considering the complexity of buildings and the working mode of renovation teams, automatic painting machines often cannot complete wall painting efficiently due to their lack of flexibility. Therefore, nowadays, most renovation work is done manually.

[0003] When decorating interiors, latex paint is often chosen to paint the walls. When painting walls manually, the paint roller is usually placed into the paint bucket until it is submerged, then removed. After waiting for the excess paint to drip back into the bucket, the wall is painted. The process is repeated after the paint on the roller is used up. Generally, to prevent paint drips from causing pollution, the first step when using a paint-laden roller is to push it forward.

[0004] Traditional painting methods require repeated dipping of paint, which is extremely tedious. Furthermore, the amount of paint applied each time is inconsistent due to the manual application method, resulting in different amounts of paint on different wall areas and affecting the final finish of the wall.

[0005] Meanwhile, for today's decoration professionals, wall painting rollers are inexpensive consumables, and because of the nature of paint and rollers, they need to be replaced frequently. Therefore, this should be taken into consideration when designing a wall painting device. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, the present invention provides a reciprocating wall painting device for building decoration, which can feed material to the roller during the painting process and can uniformly and quantitatively feed material according to the painting distance, effectively solving the problems of cumbersome and uneven feeding in current wall painting.

[0007] The technical solution adopted by the present invention is as follows: The present invention provides a reciprocating wall painting device for architectural decoration, including a replaceable roller brush, a uniform and synchronous feeding mechanism, a main rod, a preliminary feeding bin, a handle, and a hose. The preliminary feeding bin is located in the middle of the outer wall of the main rod, the handle is located at the bottom of the outer wall of the main rod, and the hose is connected to the bottom of the handle. The main rod and the handle are hollow inside. The uniform and synchronous feeding mechanism is provided at the top of the main rod. The uniform and synchronous feeding mechanism has a first bracket on one side and a second bracket on the other side. The replaceable roller brush is rotatably locked between the first bracket and the second bracket and is located above the uniform and synchronous feeding mechanism.

[0008] Furthermore, the drive gear is rotatably disposed between the end of the first bracket and the replaceable roller brush and is coaxial with the replaceable roller brush. A first buckle is fixedly provided on one side of the drive gear, and a groove is opened on one side of the replaceable roller brush to engage with the first buckle. The first buckle is engaged in the groove. A second buckle is provided at the end of the second bracket. The second buckle has a cylindrical structure and a thread on its side wall. A threaded hole is opened at the top of the second bracket to engage with the thread of the second buckle. The second buckle is rotatably disposed in the threaded hole. A second groove is opened on the other side of the replaceable roller brush. The second groove engages with the second buckle. A handle is provided on the outer side of the second buckle.

[0009] Furthermore, the uniform synchronous feeding mechanism includes an inlet channel, a screw, an outlet, and an arc-shaped baffle. The inlet channel is a pipe with a circular cross-section and is located inside the uniform synchronous feeding mechanism. The inlet channel extends from the driving gear side of the uniform synchronous feeding mechanism to the middle of the uniform synchronous feeding mechanism and extends downward to the main rod. The screw is horizontally rotatable inside the inlet channel, and the maximum radius of the screw is in contact with the inner wall of the inlet channel. The outlet is evenly distributed and opened at the top of the feeding mechanism and communicates with the inlet channel. The arc-shaped baffle is located at the top of the uniform synchronous feeding mechanism and is in contact with the replaceable roller brush.

[0010] Furthermore, a spring-loaded one-way gear is rotatably provided on one side of the uniform feeding mechanism. The screw penetrates the side wall of the uniform feeding mechanism and is fixedly connected to the spring-loaded one-way gear. A sealing ring is provided at the contact point between the screw and the inner wall of the uniform feeding mechanism. The spring-loaded one-way gear includes a three-slotted groove, a telescopic tooth, a gear spring, and a central shaft. The three-slotted groove is opened on the outside of the spring-loaded one-way gear. The spring-loaded one-way gear has a circumferential array of sliding grooves. The telescopic tooth is slidably disposed in the sliding groove and engages with the sliding groove. The top of the telescopic tooth is arranged in an arc shape from high to low. The central shaft is located in the middle of the spring-loaded one-way gear. The gear spring is fixedly disposed between the central shaft and the telescopic tooth. The spring-loaded one-way gear meshes with the driving gear. An auxiliary handle is attached to one side of the spring-loaded one-way gear. The end of the auxiliary handle is engaged with the three-slotted groove.

[0011] When the replaceable roller brush rolls forward, the gear spring lifts the telescopic teeth, the drive gear contacts the side wall of the telescopic teeth, and the drive gear drives the spring one-way gear to rotate. When the replaceable roller rolls backward, the drive gear contacts the top arc surface of the telescopic teeth and presses the telescopic teeth downward, and the spring one-way gear does not follow the movement of the drive gear.

[0012] Furthermore, the preliminary feeding bin includes an elastic airbag, an arc-shaped plate, and a perforation. The elastic airbag is sleeved on the outside of the main rod, and the arc-shaped plate is located inside the elastic airbag and fits against the inner wall of the elastic airbag. A spring assembly is provided between the arc-shaped plate and the main rod. The perforation is opened on the main rod and connects the inside of the main rod with the preliminary feeding bin. The main rod is provided with a discharge one-way valve and a feed one-way valve. The discharge one-way valve is located above the preliminary feeding bin, and the feed one-way valve is located below the preliminary feeding bin.

[0013] In use, rotate and pull out clip two, align the slot one of the replaceable roller brush with clip one and insert it, then rotate clip two into slot two to complete the installation of the replaceable roller brush. Next, insert the hose into the paint bucket, squeeze the initial feeding hopper, and the gas inside the hopper will be discharged through the discharge check valve. The elastic airbag rebounds through the arc plate and spring assembly, generating negative pressure, which draws in the gas below through the inlet check valve. Driven by the discharge check valve, the inlet check valve, and the negative pressure, the paint is drawn upwards. When the paint level reaches the hole, the paint flows into the initial feeding hopper and continues to be squeezed upwards. As the paint rises and flows out of the outlet, painting can begin. When the replaceable roller moves forward, the drive gear drives the spring-loaded one-way gear to rotate, which in turn drives the screw to rotate, continuously feeding paint from the outlet. The paint is then picked up by the replaceable roller brush. When moving backward, it functions as a regular roller brush. Preferably, to better suit actual operation, the screw's thread direction follows the direction the screw delivers paint outward as the replaceable roller brush rolls forward. When the painting height is high and replenishing paint becomes difficult due to hydraulic pressure, an auxiliary handle can be inserted into the groove to manually rotate the screw for replenishment.

[0014] The beneficial effects of the present invention using the above structure are as follows: The reciprocating wall painting device provided by this solution uses a spring-driven one-way gear and screw design to achieve automatic and uniform material replenishment during the painting process based on the forward painting distance. At the same time, this feeding method is practical and easy to learn. The replaceable roller brush design can minimize the cost of use. This method is practical, has a low learning cost, is flexible in use, and can effectively improve the efficiency of wall painting. At the same time, the structure is simple and the cost is low.

A screw hole is opened at the top of the bracket 7 to engage with the thread of the buckle 701. The buckle 701 is rotatably disposed in the screw hole. A groove 102 is opened on the other side of the replaceable roller brush 1. The groove 102 engages with the buckle 701. A handle is provided on the outside of the buckle 701.

[0028] Figure 3 and Figures 5-6As shown, a spring-loaded one-way gear 5 is rotatably mounted on one side of the uniform feeding mechanism 2. One side of the screw 502 penetrates the side wall of the uniform feeding mechanism 2 and is fixedly connected to the spring-loaded one-way gear 5. A sealing ring is provided at the contact point between the screw 502 and the inner wall of the uniform feeding mechanism 2. The spring-loaded one-way gear 5 includes a slot 501, a telescopic gear 503, a gear spring 504, and a central shaft 505. The slot 501 is located on the outside of the spring-loaded one-way gear 5. The gear 5 has a circumferential array with grooves. The telescopic tooth 503 is slidably disposed in the groove and engaged with the groove. The top of the telescopic tooth 503 is arc-shaped from high to low. The central shaft 505 is disposed in the middle of the spring one-way gear 5. The gear spring 504 is fixedly disposed between the central shaft 505 and the telescopic tooth 503. The spring one-way gear 5 meshes with the driving gear 3. An auxiliary handle 6 is attached to one side of the spring one-way gear 5. The end of the auxiliary handle 6 is engaged with the groove 3 501.

[0029] like Figures 3-4 As shown, the preliminary feeding bin 8 includes an elastic airbag 801, an arc-shaped plate 802, and a perforation 803. The elastic airbag 801 is sleeved on the outside of the main rod 9. The arc-shaped plate 802 is located inside the elastic airbag 801 and fits against the inner wall of the elastic airbag 801. A spring assembly is provided between the arc-shaped plate 802 and the main rod 9. The perforation 803 is opened on the main rod 9 and connects the inside of the main rod 9 with the preliminary feeding bin 8.

[0030] In practical use, rotate and pull out buckle 2 701, align the groove 101 of replaceable roller brush 1 with buckle 1 301 and insert it, then rotate buckle 2 701 into groove 2 102 to complete the installation of replaceable roller brush 1. Next, insert hose 11 into the paint bucket, squeeze the initial feeding chamber 8, and the gas in the chamber is discharged through discharge check valve 901. The elastic airbag 801 rebounds through the arc plate 802 and spring assembly, generating negative pressure, drawing in the gas below through inlet check valve 902, and then through outlet check valve 901... Driven by the feed check valve 902 and negative pressure, the paint is drawn upwards. When the paint level reaches the hole 803, the paint flows into the initial feed bin 8 and continues to rise upwards through compression. After the paint flows out from the discharge port 202, the painting operation can begin. When the replaceable roller moves forward, the drive gear 3 drives the spring one-way gear 5 to rotate, and the spring one-way gear 5 drives the screw 502 to rotate, continuously sending the paint out from the discharge port 202. The paint is then picked up by the replaceable roller brush 1 and used as a regular roller brush when moving backwards. This process is repeated to complete the painting operation.

[0031] Preferably, in order to fit actual operation, the thread direction of the screw 502 follows the direction that the replaceable roller brush 1 rolls forward and the screw 502 delivers paint outward. When the painting height is high and it is difficult to replenish the material due to the influence of hydraulic pressure, the auxiliary handle 6 can be inserted into the groove 3 501 to manually rotate the screw 502 to replenish the material.
