Description

A wall painting device for old house renovation Technical Field

[0001] This utility model relates to the field of painting technology, specifically a wall painting device for old house renovation. Background Technology

[0002] Old house renovation refers to the renovation and refurbishment of old houses. This includes repainting the walls. Painting equipment is used to paint the walls of old houses during the renovation process.

[0003] According to a public notice (Announcement No.: CN218508949U) of a wall painting device for old house renovation, the above application uses a horizontal extension rod and sleeve in conjunction with a drive wheel for rotating painting. A guide rod and guide groove are arranged in an S-shape. A first spring enables the painting roller to paint evenly along an S-shaped trajectory. A rack, servo motor, and swing rod enable the extension rod to rotate back and forth, allowing the guide rod to swing back and forth within the guide groove and adjust its vertical position. Compared to the original painting roller, the painting level is higher, effectively reducing the phenomenon of secondary painting, reducing paint flow on site, and improving the practicality of the device.

[0004] However, in actual use, although the above-mentioned equipment can apply paint evenly in an S-shaped trajectory, excess paint on the outer wall of the paint roller will continuously drip down during the painting process, resulting in paint waste and dirt on the ground. In view of this, we propose a wall painting device for old house renovation. Summary of the Invention

[0005] The purpose of this utility model is to provide a wall painting device for old house renovation, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wall painting device for old house renovation, comprising a vehicle body, a lifting and forward moving component provided on the outer wall of the vehicle body, an installation chamber provided on the outer wall of the lifting and forward moving component, a circulation discharge component provided on the outer wall of the installation chamber, a side plate fixedly connected to the outer wall of the installation chamber, a brush roller rotatably mounted on the outer wall of the side plate, an anti-fall component provided on the outer wall of the side plate, the anti-fall component comprising a motor, the motor fixedly connected to the outer wall of the side plate, a reciprocating threaded rod fixedly connected to the output end of the motor through the side plate, a threaded slider threadedly connected to the outer wall of the reciprocating threaded rod, and a flexible connecting rod fixedly connected to the outer wall of the threaded slider;

[0007] A resilient scraper is fixedly connected to the end of a resilient connecting rod. A fixed scraper is fixedly connected to the outer wall of the side plate, and an arc-shaped rubber block is fixedly connected to the outer wall of the installation chamber.

[0008] Preferably, the number of the arc-shaped adhesive blocks is several, and the several arc-shaped adhesive blocks are arranged in a linear array on the outer wall of the installation chamber.

[0009] Preferably, the outer wall of the brush roller is adapted to the outer wall of the fixed scraper, so that when the brush roller rotates, the fixed scraper can scrape off the paint that is about to drip.

[0010] Preferably, the centerline of the reciprocating threaded rod and the centerline of the threaded slider are on the same straight line.

[0011] Preferably, the outer wall of the installation chamber is provided with a sliding assembly, the sliding assembly including an impact plate, the impact plate being fixedly connected to the outer wall of the installation chamber, a blocking rod being fixedly connected to the outer wall of the installation chamber, a rubber rod being fixedly connected to the outer wall of the threaded slider, and an impact ball being fixedly connected to the end of the rubber rod.

[0012] Preferably, the center line of the rubber rod and the center line of the striking ball are on the same straight line, so that the rubber rod can drive the striking ball to move.

[0013] Preferably, the number of the blocking rods is two sets, and the two sets of blocking rods are arranged on both sides mirroring the center plane of the impact plate.

[0014] Compared with the prior art, this utility model provides a wall painting device for old house renovation, which has the following beneficial effects:

[0015] 1. This wall painting device for old house renovation uses a motor to drive a reciprocating threaded rod to rotate. This causes the limited threaded slider to move the flexible connecting rod and the flexible scraper. As the flexible scraper moves, it scrapes off the paint in the installation chamber and on the outer wall of the fixed scraper and pushes it to accumulate. This prevents the paint in the installation chamber from settling and solidifying before entering the circulation pipe. At the same time, it scrapes off the paint that has accumulated on the outer wall of the fixed scraper for a long time, preventing the paint from drying out continuously. When the flexible connecting rod moves, it is periodically touched by the arc-shaped rubber block. This oscillation allows the paint adhering to the outer wall of the flexible scraper to flow better into the installation chamber, ultimately enabling the paint to be effectively collected and recycled.

[0016] 2. In this old house renovation wall painting device, when the threaded slider that is limited moves, it will simultaneously drive the rubber rod and the striking ball to move. As a result, the rubber rod will be periodically squeezed and deformed by the blocking rod after the displacement. Finally, when the rubber rod and the striking ball are completely separated from the blocking rod and reset, the rubber rod will drive the striking ball to periodically strike the impact plate. Finally, through vibration, the paint adhering to the inner wall of the installation chamber can drip off better and enter the pipeline of the circulation discharge component.

[0024] As shown in Figures 1-6, this utility model provides a technical solution: a wall painting device for old house renovation, including a vehicle body 1. The outer wall of the vehicle body 1 is provided with a lifting and forward moving component 2, which can drive the installation chamber 3 to move vertically, forward and backward. The outer wall of the lifting and forward moving component 2 is provided with an installation chamber 3. The outer wall of the installation chamber 3 is provided with a circulation discharge component 4, which can collect and discharge paint liquid through a pipeline. The outer wall of the installation chamber 3 is fixedly connected with a side plate 5. A brush roller 6 is rotatably installed on the outer wall of the side plate 5. The outer wall of the side plate 5 is provided with an anti-fall component 7, which includes a motor 701. The motor 701 is fixedly connected to the outer wall of the side plate 5. The output end of the motor 701 passes through the side plate 5 and is fixedly connected with a reciprocating threaded rod 702. The outer wall of the reciprocating threaded rod 702 is threadedly connected with a threaded slider 703. The outer wall of the threaded slider 703 is fixedly connected with a flexible connecting rod 704.

[0025] Furthermore, the toughening scraper 705 is fixedly connected to the end of the toughening connecting rod 704, the outer wall of the side plate 5 is fixedly connected to the fixing scraper 706, and the outer wall of the installation chamber 3 is fixedly connected to the arc-shaped rubber block 707.

[0026] The number of arc-shaped adhesive blocks 707 is several, and the arc-shaped adhesive blocks 707 are arranged in a linear array on the outer wall of the mounting chamber 3. The outer wall of the brush roller 6 is adapted to the outer wall of the fixed scraper 706, so that when the brush roller 6 rotates, the fixed scraper 706 can scrape off the paint that is about to drip. The center line of the reciprocating threaded rod 702 and the center line of the threaded slider 703 are on the same straight line.

[0027] Furthermore, the outer wall of the installation chamber 3 is provided with a sliding assembly 8, which includes an impact plate 801. The impact plate 801 is fixedly connected to the outer wall of the installation chamber 3. A blocking rod 802 is fixedly connected to the outer wall of the installation chamber 3. A rubber rod 803 is fixedly connected to the outer wall of the threaded slider 703. A striking ball 804 is fixedly connected to the end of the rubber rod 803. The center line of the rubber rod 803 and the center line of the striking ball 804 are on the same straight line, so that the rubber rod 803 can drive the striking ball 804 to move. There are two sets of blocking rods 802, and the two sets of blocking rods 802 are mirror images of the center plane of the impact plate 801 on both sides.

[0028] In the embodiments of this utility model, during daily use, the vehicle body 1 is first moved to the old house wall that needs to be painted, then an appropriate amount of paint is added to the installation chamber 3, and the circulation discharge component 4 is activated. Finally, the lifting and forward moving component 2 can be lifted and moved forward, so that the installation chamber 3 can be moved to a suitable position, which is convenient for driving the brush roller 6 to lift and paint. When the paint discharged by the circulation discharge component 4 flows onto the brush roller 6, the brush roller 6 can be painted by the reciprocating lifting and moving component 2. At the same time, when the brush roller 6 is rotating, the fixed scraper 706 can scrape off the paint that is about to drip.

[0029] At this time, the start motor 701 drives the reciprocating threaded rod 702 to rotate, causing the limited threaded slider 703 to move the flexible connecting rod 704 and the flexible scraper 705. This allows the flexible scraper 705 to scrape off and push the paint in the installation chamber 3 and on the outer wall of the fixed scraper 706 during displacement, preventing the paint in the installation chamber 3 from settling and solidifying before entering the circulation pipe. At the same time, it can scrape off the paint that has accumulated on the outer wall of the fixed scraper 706 for a long time, preventing the paint from continuously accumulating and drying on the outer wall of the fixed scraper 706. When the flexible connecting rod 704 is displaced, it is periodically touched by the arc-shaped rubber block 707, which causes the paint adhering to the outer wall of the flexible scraper 705 to flow better into the installation chamber 3 through oscillation, so that the paint can be effectively collected and recycled.

[0030] In this invention, when the threaded slider 703 is displaced, it simultaneously drives the rubber rod 803 and the striking ball 804 to move. As a result, the rubber rod 803 is periodically squeezed and deformed by the blocking rod 802 after displacement. Finally, when the rubber rod 803 and the striking ball 804 are completely separated from the blocking rod 802 and reset, the rubber rod 803 will drive the striking ball 804 to periodically strike the impact plate 801. Finally, the vibration allows the paint adhering to the inner wall of the installation chamber 3 to drip off better and enter the pipeline of the circulation discharge component 4.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
