Description

Technical Field

[0001] This invention relates to the field of architectural wall painting technology, specifically to an equipment for painting interior walls and a painting method thereof. Background Technology

[0002] Painting building walls is an important part of building decoration, with the main purpose of making the walls smooth and neat. Building wall painting equipment is mainly divided into: spraying machine: it has functions such as adjusting spraying pressure, spraying angle and spraying mode, which can adapt to different painting needs; mixer: usually driven by electric or pneumatic, with high efficiency and energy saving; roller coating machine: suitable for painting large areas such as walls and ceilings; brush coating machine: suitable for painting details and corners, and can perform fine painting work.

[0003] The prior art, authorized by patent announcement number CN111927061B, discloses a special wall spraying and painting device for building interior decoration. This patent includes a movable base, a mixing tank, and a U-shaped adjusting seat. The movable base has casters installed at its four corners. Two sets of mounting slots for the mixing tank are symmetrically opened on one side of the upper surface of the movable base, and a storage slot for the mixing tank is opened on the side of the movable base away from the mounting slots. Push rods for easy gripping are provided on both sides of the movable base. The mixing tank is a cylindrical structure with an internal mixing chamber. A set of rotary motors is installed at the top center of the mixing tank, and a set of stirring shafts extending into the mixing chamber are fitted at the bottom of the rotary motors. The axis of the stirring shafts is aligned with the axis of the mixing tank. Multiple sets of stirring paddles are equidistantly arranged on the outer edge of the stirring shafts. This patent has a reasonable structure, easily achieves automated spraying and painting, effectively realizes alternating material supply, and is highly practical.

[0004] However, this patent uses a rotary motor to mix materials, but during use, after the materials are mixed, the motor needs to be turned on again for intermittent mixing to prevent the materials from solidifying due to prolonged standing, which would affect subsequent painting work. Also, when the U-shaped adjusting seat moves, the pump hose is placed on the moving base and moved up and down by the U-shaped adjusting seat. After a long period of use, the pump hose may become knotted or damaged, affecting the material conveying and the use of the equipment. During painting, the paint on the felt roller will fall to the ground and onto the right-angle corners of the walls and floors, which is difficult to clean. Summary of the Invention

[0017] A method for painting interior walls, using the aforementioned interior wall painting equipment, includes the following specific steps:

[0018] S1. When the drive motor starts, it drives the sliding seat and felt roller to move up and down, while the drive shaft rotates through the drive bevel gear and the driven bevel gear.

[0019] S2. The drive shaft drives the driven shaft to rotate, and the rotation of the two stirring shafts is achieved through the setting of two transmission belts, thereby realizing the stirring of materials;

[0020] S3. The driven shaft rotates the rotating rod via the conveyor belt, thereby driving the carrying bucket to rotate.

[0021] S4. The rotating rod drives the transmission shaft to rotate, which in turn drives the rotating shaft to rotate, thus realizing the rotation of the disc, which in turn realizes the up-and-down reciprocating motion of the sliding rod, ensuring stable feeding.

[0023] The working principle and beneficial effects of this invention are as follows:

[0024] 1. This invention, through the arrangement of a drive shaft and a driven shaft, drives the sliding seat to move up and down while simultaneously rotating the drive shaft. The drive shaft then drives the driven shaft to rotate, and the rotation of the stirring shaft is achieved through the transmission belt, thereby realizing the stirring of materials. At the same time, the materials inside the material tank are continuously stirred while the painting work is being carried out, effectively avoiding the phenomenon of solidification caused by the materials standing still. It also saves on the power consumption and installation costs of multiple motors such as the drive motor and the stirring motor.

[0025] 2. This invention, through the arrangement of rotating rods, discs, and other structures, allows the driven shaft to rotate, driving the stirring shaft to stir while simultaneously rotating the rotating rod, thereby rotating the carrying container. This causes the material inside the carrying container to slosh around. At the same time, the meshing of the driving and driven sector gears enables the rotation of the transmission shaft, which in turn causes the disc to rotate. This, in turn, causes the sliding rod to move up and down reciprocally, thereby achieving the collection and orderly loading and unloading of the conveying pipe, ensuring the transportation of materials and guaranteeing work efficiency.

[0026] 3. This invention, through the setting of structures such as a collection bin and locking blocks, rotates the irregularly shaped disc to realize the movement of two locking blocks, and uses a retaining spring to realize the reset of the locking blocks, thereby realizing the installation and disassembly of the collection bin, which facilitates the collection of waste paint on the felt roller, and also facilitates the disposal of waste paint after the painting work is completed.

[0043] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0044] Example 1, as Figures 1-9As shown, this embodiment proposes a wall painting device for interior decoration, including a base 1 and a sliding seat 2. A rack plate 9 and two symmetrically arranged columns 6 are fixedly connected to the top of the base 1. The sliding seat 2 is slidably mounted on both columns 6. A drive motor 10 is installed on the sliding seat 2. The output end of the drive motor 10 is connected to a coaxially arranged drive shaft 11 via a coupling. A drive gear 12 is fixedly connected to one end of the drive shaft 11. Two material tanks 13 and two suction pumps 15 are respectively installed on the base 1. Several equally spaced, arrayed spray nozzles 16 are installed on the sliding seat 2. Both sides of the sliding seat 2 are fixedly connected to fixed plates 17, and felt rollers 7 are rotatably mounted on the two fixed plates 17. A square plate 8 is fixedly connected to one side of the rack plate 9. Feed hoppers 14 are installed on both material buckets 13. A collecting device 5 is provided on the sliding seat 2. A stirring auxiliary device 3 is provided on both the base 1 and the sliding seat 2. The stirring auxiliary device 3 includes a drive shaft 30, which is rotatably mounted on the base 1 and the square plate 8. A driven shaft 31 is rotatably mounted on both the base 1 and the square plate 8. Small teeth are fixedly sleeved on the outer circumferential surfaces of the drive shaft 30 and the driven shaft 31 respectively. Wheel 32 and large gear 33, sliding sleeve 37 is slidably mounted on the outer circumferential surface of drive shaft 30, wheel axle 35 is rotatably mounted on sliding seat 2, driven bevel gear 36 and drive bevel gear 34 are respectively fixedly sleeved on the outer circumferential surface of wheel axle 35 and drive shaft 11, synchronous belt 38 is mounted on wheel axle 35 and sliding sleeve 37, two symmetrically arranged fixed rods 39 are fixedly connected to the outer circumferential surface of drive shaft 30, stirring shaft 301 is rotatably mounted inside both material barrels 13, drive belt 300 is mounted on the outer circumferential surface of driven shaft 31 and stirring shaft 301, driven shaft 31 and bottom A feeding auxiliary device 4 is provided on the seat 1. Through the arrangement of the drive shaft 30, driven shaft 31 and other structures, the drive shaft 11 rotates and drives the sliding seat 2 to move up and down, while driving the drive shaft 30 to rotate. The drive shaft 30 drives the driven shaft 31 to rotate. The transmission belt 300 causes the stirring shaft 301 to rotate, thereby realizing the stirring of materials. At the same time, the materials inside the material bucket 13 are continuously stirred while the painting work is being carried out, which effectively avoids the phenomenon of solidification caused by the material standing still. It also saves the power consumption and installation cost of multiple motors such as the drive motor 10 and the stirring motor.

[0045] like Figures 1-6 As shown, the drive gear 12 meshes with the rack plate 9, the driving bevel gear 34 meshes with the driven bevel gear 36, the large gear 33 meshes with the small gear 32, and the sliding seat 2 has four symmetrically arranged through holes, and the two columns 6 pass through the interior of the four through holes respectively.

[0046] like Figures 1-6As shown, two drive wheels are fixedly sleeved on the outer circumferential surface of the driven shaft 31, and drive wheels are fixedly sleeved on the outer circumferential surface of the two stirring shafts 301. The drive belt 300 is installed on the outer circumferential surface of each pair of drive wheels. Synchronous pulleys are fixedly sleeved on the outer circumferential surface of the sliding sleeve 37 and the wheel axle 35. The synchronous belt 38 is installed on the outer circumferential surface of the two synchronous pulleys.

[0047] like Figure 6 As shown, a circular groove is provided on the sliding sleeve 37, and the drive shaft 30 passes through the inside of the circular groove. Two square grooves are provided on the sliding sleeve 37, which are symmetrically arranged and connected to the circular groove. The fixing rod 39 passes through the inside of the square groove.

[0048] In this embodiment, the drive motor 10 starts and drives the drive shaft 11 to rotate, which in turn drives the drive gear 12 to rotate, thereby raising and lowering the sliding seat 2. The drive shaft 11 drives the active bevel gear 34 to rotate, which in turn drives the driven bevel gear 36 to rotate, thereby causing the wheel axle 35 to rotate. The sliding sleeve 37 rotates through the synchronous belt 38. The sliding sleeve 37 drives the active shaft 30 to rotate through two fixed rods 39. The active shaft 30 drives the small gear 32 to rotate, which in turn drives the large gear 33 to rotate. The large gear 33 drives the driven shaft 31 to rotate. The driven shaft 31 moves the stirring shaft 301 through two transmission belts 300. This causes the sliding seat 2 to rise and fall while painting, and simultaneously drives the stirring shaft 301 to stir the material inside, maintaining the activity of the material. The upper and lower ends of the sliding sleeve 37 abut against the sliding seat 2, so that the sliding seat 2 rises and falls simultaneously with the sliding sleeve 37, thereby ensuring that the sliding sleeve 37 drives the active shaft 30 to rotate.

[0049] Example 2, as Figures 1-9As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes a feeding auxiliary device 4 including two carrying buckets 40. Two symmetrically arranged support plates 402 are fixedly connected to the base 1. The carrying buckets 40 are rotatably mounted on the top of the support plates 402. A rotating rod 41 is fixedly connected to the bottom of the carrying buckets 40. Two transmission shafts 42 and two rotating shafts 43 are rotatably mounted on the base 1. A driving sector gear 44, a driven sector gear 45, and a disc 46 are fixedly sleeved on the outer circumferential surfaces of the rotating rod 41, the transmission shaft 42, and the rotating shaft 43, respectively. Four symmetrically arranged directional rods 47 are fixedly connected to the base 1. A sliding rod 48 is slidably assembled on the outer circumferential surface of every two directional rods 47. A sliding column 49 is fixedly connected to one side of the disc 46. A through groove is provided on the top, and a roller is installed inside the through groove. A first conveyor belt 400 is installed on the driven shaft 31 and two rotating rods 41. A second conveyor belt 401 is installed on the outer circumference of the drive shaft 42 and the rotating shaft 43. Through the arrangement of rotating rods 41, discs 46 and other structures, the rotation of the driven shaft 31 drives the stirring shaft 301 to stir, and at the same time drives the rotating rods 41 to rotate, thereby realizing the rotation of the carrying bucket 40, so that the material inside the carrying bucket 40 can be shaken. At the same time, due to the meshing of the driving sector gear 44 and the driven sector gear 45, the drive shaft 42 rotates, which in turn realizes the rotation of the disc 46, thereby making the sliding rod 48 move up and down reciprocally, so as to realize the collection and orderly opening and closing of the conveying pipe, ensuring the transportation of materials and ensuring work efficiency.

[0050] like Figures 1-3 As shown, the driving sector gear 44 and the driven sector gear 45 mesh with each other. Two conveyor wheels are fixedly mounted on the outer circumferential surface of the driven shaft 31. Conveyor wheels are fixedly mounted on the outer circumferential surface of the two rotating rods 41. Conveyor belts 400 are installed together on the outer circumferential surface of each pair of conveyor wheels. Conveyor wheels are fixedly mounted on the outer circumferential surface of the drive shaft 42 and the rotating shaft 43. Conveyor belts 401 are installed together on the outer circumferential surface of the two conveyor wheels.

[0051] like Figures 2-4 As shown, a sliding groove is provided on the sliding rod 48, and the sliding column 49 is located inside the sliding groove. Two symmetrically arranged directional holes are provided on the sliding rod 48, and the directional rod 47 passes through the interior of the directional holes.

[0052] In this embodiment, the suction pump 15 draws material from the material tank 13 through the pumping hose and transports it to the carrying tank 40. Then, the material is transported to the sliding seat 2 through the hose wound around the carrying tank 40. The driven shaft 31 drives two rotating rods 41 to rotate via the conveyor belt 400. The rotating rods 41 drive the carrying tank 40 to rotate. Due to the arrangement of the large gear 33 and the small gear 32, the rotation speed of the driving shaft 30 is lower than that of the driven shaft 31, resulting in a lower rotation speed of the rotating rods 41. This allows the speed at which the carrying tank 40 rotates to extend and retract the hose to match the moving speed of the sliding seat 2. The through grooves on the sliding rods 48 are all rounded, and the cooperation of the rollers allows the hose to be more... The flexible protection prevents damage to the hose from the edge of the trough. The rotating rod 41 drives the active sector gear 44 to rotate, which in turn drives the driven sector gear 45 to rotate. The driven sector gear 45 drives the drive shaft 42 to rotate, which in turn drives the rotating shaft 43 to rotate via the conveyor belt 401. The rotating shaft 43 drives the disc 46 to rotate, which in turn drives the sliding column 49 to rotate. The sliding column 49 slides inside the trough, causing the sliding rod 48 to move. The two directional rods 47 restrict the sliding rod 48 to slide up and down along the directional rods 47, thus ensuring that the hose is neatly and orderly wound on the carrying bucket 40, avoiding knots and other issues that may affect the material conveying.

[0053] Example 3, as Figures 1-9 As shown, based on the same concept as Embodiments 1 and 2 above, this embodiment also proposes a collection device 5 including a collection chamber 50. Two symmetrically arranged mounting blocks 51 are fixedly connected to one side of the collection chamber 50. Two symmetrically arranged mounting slots 57 and four locking holes 58 are respectively opened on the sliding seat 2. A round rod 52 is rotatably installed inside the mounting block 51. A shaped disk 54 and a turntable are fixedly connected to both ends of the round rod 52, respectively. Two symmetrically arranged locking blocks 53 are slidably assembled inside the mounting block 51. A pull rod 55 is fixedly connected to one side of the locking block 53. One end of each of the two pull rods 55 is slidably assembled on the shaped disk 54. Through the arrangement of the collection chamber 50, locking blocks 53 and other structures, rotating the shaped disk 54 realizes the movement of the two locking blocks 53. The locking blocks 53 are reset by the snap ring 56, thereby realizing the installation and disassembly of the collection chamber 50, which facilitates the collection of waste paint on the felt roller 7, and also facilitates the disposal of waste paint after the painting work is completed.

[0054] like Figure 9 As shown, the mounting block 51 has two symmetrically arranged slots, the locking block 53 is slidably connected inside the slots, the outer circumferential surface of the pull rod 55 is fitted with a retaining spring 56, and the retaining spring 56 is connected between the locking block 53 and the inner wall of the slot. The irregular disc 54 has a rolling groove, and one end of the pull rod 55 is slidably connected inside the rolling groove.

[0055] In this embodiment, the rotation of the round rod 52 drives the shaped disk 54 to rotate, and the rotation of the shaped disk 54 drives the two pull rods 55 to move. The pull rods 55 drive the locking block 53 to move into the slot, reverse the shaped disk 54, and the locking block 53 is reset by the setting of the locking spring 56 and locked into the locking hole 58, so as to realize the installation and removal of the collection chamber 50. The collection chamber 50 is installed before painting to facilitate the collection of waste paint on the felt roller 7. After painting is completed, the collection chamber 50 is removed to facilitate the disposal of waste paint by the staff.

[0056] A method for painting interior walls, using the aforementioned interior wall painting equipment, includes the following steps: S1, the drive motor 10 starts, driving the sliding seat 2 and felt roller 7 to move up and down, while simultaneously rotating the drive shaft 30 via the drive bevel gear 34 and driven bevel gear 36; S2, the drive shaft 30 drives the driven shaft 31 to rotate, and the two mixing shafts 301 rotate via two transmission belts 300, thereby achieving material mixing; S3, the driven shaft 31 rotates the rotating rod 41 via the conveyor belt 400, thereby driving the carrying bucket 40 to rotate; S4, the rotating rod 41 drives the transmission shaft 42 to rotate, and the transmission shaft 42 drives the rotating shaft 43 to rotate, thereby achieving the rotation of the disc 46, and thus achieving the up-and-down reciprocating motion of the sliding rod 48, ensuring stable feeding; S5, before painting, the collection bin 50 is installed to collect waste paint falling from the felt roller 7, and after painting, the collection bin is disassembled for waste paint disposal.

[0057] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
