Description

Technical Field

[0001] This utility model relates to the field of decoration equipment technology, and in particular to a house wall painting device. Background Technology

[0002] Latex paint, a common name for latex coatings, originated in the mid-to-late 1970s. It is a large category of synthetic resin emulsion coatings, represented by acrylic copolymer emulsions. Latex paint is a water-dispersible coating. It is made by using synthetic resin emulsions as a base material, with fillers ground and dispersed, and then adding various additives to refine the coating. Currently, the real estate industry remains hot, and housing is always the guarantee of a stable and prosperous life. Decoration is the stage before moving in, and painting the walls is basically an essential step.

[0003] Currently available technologies involve manual painting. The conventional operation involves an operator holding a roller brush and painting the wall with the handle tilted towards the wall. When using the roller brush, it is necessary to frequently dip it in latex paint. At the same time, it is impossible to control the amount of latex paint dipped in, which makes it easy for the latex paint to flow down the roller surface due to gravity, onto the handle, or even drip onto the floor or floor tiles, resulting in waste.

[0004] Therefore, it is necessary to provide a new device for painting house walls to solve the above-mentioned technical problems. Utility Model Content

[0005] To address the technical problems of difficulty in controlling the amount of paint applied and waste caused by dripping during latex paint application, this utility model provides a device for painting house walls.

[0006] The wall painting device provided by this utility model includes: a base and a placement groove opened on the top of the base for placing a paint bucket; a support plate provided on the base; a telescopic rod provided on the base, on which a roller brush is installed; a pump body fixedly installed on the top of the support plate for pumping latex paint from the paint bucket into the roller brush; a connecting pipe installed on the discharge end of the roller brush and the pump body; and a fixing mechanism provided on the base for fixing the paint bucket.

[0007] Preferably, the roller brush consists of a bracket, a discharge cylinder, a paint brush, and a pipe connector. The bracket is threaded onto the threaded cylinder of the telescopic rod, the discharge cylinder is rotatably mounted on the bracket, and the discharge cylinder has multiple discharge holes. The paint brush is sleeved on the discharge cylinder, and the pipe connector is installed on the pipe of the discharge cylinder and connected to the connecting pipe.

[0008] Preferably, the support plate is provided with a scraping mechanism for cleaning latex paint adhering to the inner wall of the paint bucket. The scraping mechanism includes: a scraper blade located below the support plate and inserted into the paint bucket; an annular groove formed at the bottom of the support plate, in which an annular frame is rotatably mounted; a gear ring fixedly mounted at the bottom of the annular frame for driving the scraper blade to rotate; a drive gear rotatably mounted at the bottom of the support plate for driving the gear ring to rotate, the drive gear meshing with the gear ring; a motor fixedly mounted at the top of the support plate, with bevel gears fixedly sleeved on both the motor output shaft and the drive gear shaft, the two bevel gears meshing with each other; and an adjustment mechanism provided on the gear ring for adjusting the rotation diameter of the scraper blade.

[0009] Preferably, the adjusting mechanism includes: a connecting frame fixedly installed at the bottom of the gear ring; a slide rod fixedly installed on the connecting frame; a slider slidably installed on the slide rod for driving the scraper to move left and right, the slider being fixedly connected to the scraper; and a fastening bolt threaded onto the slider for fixing the slider.

[0010] Preferably, a hydraulic cylinder, a collection box, and a fixing cylinder are fixedly installed on the top of the base. The hydraulic cylinder is used to adjust the height of the support plate and the scraper. The collection box is used to store the connecting pipe. The fixing cylinder is used to store the telescopic rod. An L-shaped baffle for protecting the drive gear is fixedly installed on the bottom of the support plate.

[0011] Preferably, the fixing mechanism includes: a bidirectional screw rotatably mounted on the top of the base; a set of clamping plates threaded onto the bidirectional screw and used to clamp the paint bucket, each of the clamping plates being equipped with an anti-slip pad; and a handle fixedly mounted on one end of the bidirectional screw for rotating the bidirectional screw.

[0012] Preferably, a guide rod is provided on one side of the bidirectional screw, the guide rod is slidably connected to a set of clamping plates, and a counterweight is fixedly installed on the top of the support plate, the counterweight being away from the motor.

[0013] Compared with related technologies, the house wall painting device provided by this utility model has the following beneficial effects:

[0014] This utility model provides a device for painting house walls:

[0015] By combining the base, placement slot, pump body and fixing mechanism, the paint bucket fixing and automatic paint supply are integrated, reducing the manual paint dipping process and improving painting efficiency. The telescopic rod and roller brush can adapt to wall work at different heights, reducing the risk of working at height. The roller brush adopts a split design (discharge cylinder, paint brush, bracket), and the threaded installation makes it easy to quickly disassemble and replace. At the same time, the discharge cylinder has a multi-hole structure to allow the latex paint to penetrate evenly to the paint brush, avoiding paint accumulation and improving the uniformity of wall painting.

[0016] The motor drives the scraper to rotate, automatically cleaning residual latex paint from the inner wall of the paint bucket and reducing paint waste (especially for viscous latex paint). At the same time, the annular groove and gear ring transmission structure is designed to be stable and ensure that the scraper is subjected to uniform force when rotating. The sliding rod and slider adjustment mechanism can be adapted to paint buckets of different diameters. The position is locked by fastening bolts, making operation simple and reliable. The scraper is designed to fit closely to the inner wall to maximize the scraping effect and further reduce the amount of residue.

[0017] The hydraulic cylinder allows for precise height adjustment of the scraping mechanism, facilitating paint bucket replacement. The collection box and fixing cylinder respectively house the connecting pipe and telescopic rod, preventing pipe tangling or component loss and improving portability. The fixing mechanism, combining a two-way screw and a clamping plate, allows for one-handed operation with high efficiency. The anti-slip pad enhances the stability of the paint bucket, preventing it from shaking during pump operation. The guide rod ensures horizontal movement of the clamping plate, and the counterweight balances the weight on the motor side, preventing the device from tipping over due to instability.

The wall painting device includes: a base 1 and a placement groove 2 on the top of the base 1 for placing a paint bucket; a support plate 3 on the base 1; a telescopic rod 4 on the base 1, with a roller brush 5 mounted on the telescopic rod 4; a pump body 6 fixedly installed on the top of the support plate 3 for pumping latex paint from the paint bucket into the roller brush 5; a connecting pipe 7 installed on the discharge end of the roller brush 5 and the pump body 6; and a fixing mechanism on the base 1 for fixing the paint bucket. Through the combination of the base 1, placement groove 2, pump body 6, and fixing mechanism, paint bucket fixing and automatic paint supply are integrated, reducing manual paint application and improving painting efficiency. The cooperation between the telescopic rod 4 and the roller brush 5 can adapt to wall work at different heights, reducing the risk of working at heights.

[0027] The roller brush 5 consists of a bracket, a discharge cylinder 51, a paint brush 52, and a pipe connector. The bracket is threaded onto the threaded cylinder of the telescopic rod 4. The discharge cylinder 51 is rotatably mounted on the bracket and has multiple discharge holes. The paint brush 52 is sleeved on the discharge cylinder 51. The pipe connector is installed on the pipe of the discharge cylinder 51 and is connected to the connecting pipe 7. The roller brush 5 adopts a split design (discharge cylinder 51, paint brush 52, bracket), and the threaded installation facilitates quick disassembly and replacement. At the same time, the discharge cylinder 51 has a porous structure that allows the latex paint to penetrate evenly into the paint brush, avoiding paint accumulation and improving the uniformity of wall painting.

[0028] The support plate 3 is equipped with a scraping mechanism for cleaning latex paint adhering to the inner wall of the paint bucket. The scraping mechanism includes: a scraper 8 located below the support plate 3 and inserted into the paint bucket; an annular groove 9 formed at the bottom of the support plate 3, in which an annular frame 10 is rotatably mounted; a gear ring 11 fixedly mounted at the bottom of the annular frame 10 for driving the scraper 8 to rotate; and a drive gear 12 rotatably mounted at the bottom of the support plate 3 for driving the gear ring 11 to rotate, the drive gear 12 meshing with the gear ring 11. A motor 13 is fixedly installed on the top of the support plate 3. Both the output shaft of the motor 13 and the rotating shaft of the drive gear 12 are fixedly fitted with bevel gears 14, and the two bevel gears 14 mesh with each other. An adjustment mechanism is provided on the gear ring 11 to adjust the rotation diameter of the scraper 8. The scraper 8 is driven to rotate by the motor 13 to automatically clean the residual latex paint on the inner wall of the paint bucket and reduce paint waste (especially for viscous latex paint). At the same time, the transmission structure of the annular groove 9 and the gear ring 11 is designed to be stable, ensuring that the scraper 8 is subjected to uniform force when rotating.

[0029] The adjustment mechanism includes: a connecting frame 15 fixedly installed at the bottom of the toothed ring 11; a slide rod 16 fixedly installed on the connecting frame 15; a slider 17 slidably installed on the slide rod 16 for moving the scraper 8 left and right, the slider 17 being fixedly connected to the scraper 8; and a fastening bolt 18 threadedly installed on the slider 17 for fixing the slider 17. The adjustment mechanism of the slide rod 16 and the slider 17 can be adapted to paint buckets of different diameters, and the position is locked by the fastening bolt 18. The operation is simple and the fixation is reliable. The design of the scraper 8 closely adhering to the inner wall maximizes the scraping effect and further reduces the amount of residue.

[0030] A hydraulic cylinder 19, a collection box 20, and a fixing cylinder 21 are fixedly installed on the top of the base 1. The hydraulic cylinder 19 is used to adjust the height of the support plate 3 and the scraper 8. The collection box 20 is used to store the connecting pipe 7.

[0031] The fixing mechanism includes: a bidirectional screw 23 rotatably mounted on the top of the base 1; a set of clamping plates 24 threaded onto the bidirectional screw 23 for clamping the paint bucket, each of the clamping plates 24 being equipped with an anti-slip pad; and a handle 25 fixedly mounted on one end of the bidirectional screw 23 for rotating the bidirectional screw 23. Through the fixing mechanism combining the bidirectional screw 23 and the clamping plates 24, it is possible to operate with one hand, which is highly efficient. The anti-slip pads can enhance the stability of the paint bucket and prevent the bucket from shaking when the pump body 6 is working.

[0032] A guide rod 26 is provided on one side of the bidirectional screw 23. The guide rod 26 is slidably connected to a set of clamping plates 24. A counterweight 27 is fixedly installed on the top of the support plate 3. The counterweight 27 is away from the motor 13. The guide rod 26 ensures that the clamping plate 24 moves horizontally. The counterweight 27 balances the weight on the side of the motor 13, preventing the device from tipping over due to instability.

[0033] It is worth noting that the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0034] The working principle of the house wall painting device provided by this utility model is as follows:

[0035] This solution also includes an electrical control cabinet, which is installed on the equipment. During use, each piece of electrical equipment can be started and operated separately through the electrical control cabinet. The power connection method of each piece of electrical equipment is an existing mature technology and is well known to those in the field, so it will not be described in detail here.

[0036] When in use, first take out the telescopic rod 4 from the fixed cylinder 21, then adjust the length of the telescopic rod 4 to match the height of the wall to be painted, then take out the connecting pipe 7 from the collection box 20 and install its two ends on the pipe joint of the roller brush 5 and the discharge end of the pump body 6 respectively.

[0037] Then, start the hydraulic cylinder 19, which drives the support plate 3 and scraper 8 to slide upward to a certain height. Then, place the paint bucket in the placement slot 2, turn the handle 25, which drives the double screw 23 to rotate. The double screw 23 drives a set of clamping plates 24 to slide relative to each other, so that the set of clamping plates 24 clamps the paint bucket and fixes it. Then, adjust the rotation diameter of the scraper 8 according to the size of the paint bucket to match the diameter of the paint bucket.

[0038] When adjusting the scraper 8, first rotate the fastening bolt 18 to make its top end rotate away from the slide bar 16, then slide the slider 17 to make the scraper 8 position inside the paint bucket, then start the hydraulic cylinder 19, the hydraulic cylinder 19 drives the support plate 3 and the scraper 8 to slide down, at this time, the scraper 8 is inserted into the paint bucket, then slide the slider 17 again to make one side of the scraper 8 close to the inner wall of the paint bucket, then rotate the fastening bolt 18 to fix the slider 17.

[0039] When painting the wall, the operator first holds the telescopic rod 4 so that the roller brush 5 contacts the wall surface. Then, the pump body 6 is started so that the pump body 6 pumps the latex paint into the discharge cylinder 51. Then, the paint seeps into the paint brush 52 through the discharge hole in the discharge cylinder 51. Finally, the latex paint is evenly applied to the wall by the roller brush 5.

[0040] As the pump body 6 continuously supplies paint to the roller brush 5, the liquid level in the paint bucket continuously decreases. When the liquid level is below half of the paint bucket, the motor 13 is started. The output shaft of the motor 13 drives the bevel gear 14 to rotate, which in turn drives the drive gear 12 to rotate. The drive gear 12 drives the gear ring 11 to rotate, which in turn drives the ring frame 10 to rotate along the annular groove 9. At the same time, the gear ring 11 synchronously drives the scraper 8 to rotate, so that the scraper 8 scrapes off the latex paint on the inner wall of the paint bucket, which helps to reduce the waste of latex paint.

[0041] Compared with related technologies, the house wall painting device provided by this utility model has the following beneficial effects:

[0042] This utility model provides a wall painting device. Through the combination of a base 1, a placement groove 2, a pump body 6, and a fixing mechanism, it integrates paint bucket fixing and automatic paint supply, reducing manual paint application and improving painting efficiency. The telescopic rod 4 and the roller brush 5 can adapt to wall work at different heights, reducing the risk of working at heights. The roller brush 5 adopts a split design (discharge cylinder 51, paint brush 52, bracket), and the threaded installation facilitates quick disassembly and replacement. Simultaneously, the discharge cylinder 51 has a multi-hole structure to allow latex paint to evenly penetrate the paint brush, preventing paint accumulation and improving the uniformity of wall painting. The motor 13 drives the scraper 8 to rotate, automatically cleaning residual latex paint from the inner wall of the paint bucket, reducing paint waste (especially for viscous latex paint). At the same time, the annular groove 9 and the toothed ring 11 transmission structure are designed for stability, ensuring even force distribution when the scraper 8 rotates.

[0043] The sliding mechanism of slide bar 16 and slider 17 can be used to adjust paint buckets of different diameters. The position is locked by fastening bolt 18, which is simple to operate and reliable. The design of scraper 8 close to the inner wall maximizes the scraping effect and further reduces the amount of residue. The hydraulic cylinder 19 enables precise height adjustment of the scraping mechanism, which is convenient for changing paint buckets. The collection box 20 and the fixed cylinder respectively store the connecting pipe 7 and the telescopic rod 4, avoiding pipe tangling or loss of parts and improving portability. The fixing mechanism of bidirectional screw 23 and clamping plate 24 can be operated with one hand, which is highly efficient. The anti-slip pad can enhance the stability of the paint bucket and prevent the bucket from shaking when the pump body 6 is working. The guide rod 26 ensures that the clamping plate 24 moves horizontally. The counterweight 27 balances the weight on the side of the motor 13 to prevent the device from tipping over due to instability.
