Description

Technical Field

[0001] This invention relates to the field of wall sanding equipment technology, and specifically to a wall sanding device for decoration construction. Background Technology

[0002] In the decoration and construction process, wall sanding is a very important step. It is done by using sandpaper or mechanical tools to make the putty layer smooth and even, eliminating minor imperfections such as putty layer joints and pinholes, improving the overall flatness of the wall surface, and enhancing the adhesion and visual effect of subsequent paint.

[0003] Currently, wall sanding commonly uses mature electric sanding equipment. These devices are equipped with circular sandpaper, which is rotated by a sanding disc to sand the wall putty layer. However, existing electric sanding equipment is suitable for quick sanding of the middle area of ​​the wall. For the inside corners between adjacent walls, existing equipment struggles to achieve proper sanding, and it's difficult to correct the flatness and angle of the edges. These inside corners are often manually sanded by holding a sandpaper holder back and forth, which is laborious and inefficient. While some devices exist that allow sandpaper to sand the edges and corners, they lack side support, and the sanding position relies entirely on manual control. This can easily lead to over-sanding of edges and corners and damage to the verticality of the wall at the inside corners, resulting in unsatisfactory sanding results. Therefore, a wall sanding device for decoration construction is needed to solve these problems. Summary of the Invention

[0004] The purpose of this invention is to provide a wall grinding and treatment device for decoration construction, so as to solve the problems existing in the prior art mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0037] Please see Figure 1-9 The present invention provides the following technical solutions:

[0038] A wall sanding device for decoration construction includes: a housing 1, a side cover 2 rotatably connected to the side of the housing 1, the housing 1 and the side cover 2 forming an integral circular structure; a circular groove is provided on one end face of the housing 1, and a sanding disc 3 is connected to the circular groove through a rotating shaft, a circular sandpaper 4 is installed on the working surface of the sanding disc 3, and the sanding disc 3 drives the circular sandpaper 4 to rotate, which can achieve sanding of the wall putty layer; both the sanding disc 3 and the circular sandpaper 4 are provided with several through holes for dust to pass through, and the housing 1 is provided with a dust suction hole 9. By connecting a dust suction pipe to the dust suction hole 9, the dust from sanding on the wall surface during construction will be sucked into a vacuum cleaner and collected through the through holes on the sanding disc 3 and the circular sandpaper 4 and the dust suction hole 9.

[0039] The upper end face of the housing 1 is slidably connected with a buckle 14 for fixing the side cover 2. The arc surface of the side cover 2 is provided with a groove corresponding to the buckle 14. The sliding buckle 14 can release the locking relationship. Magnets 15 are provided on both sides of the end face of the side cover 2. Magnets 15 are also provided on the end face of the housing 1 that is closed with the side cover 2. When the side cover 2 is in the closed state, the magnets 15 can realize the positioning of the side cover 2.

[0040] Both the housing 1 and the side cover 2 are provided with light strips 10 for illuminating the wall surface. The light strips 10 are used to illuminate the wall surface, making it easier for the construction worker to observe the flatness of the wall surface. The housing 1 is provided with bristles 11 on the side of the end face of the grinding disc 3. The bristles 11 are used to remove the dust attached to the wall surface after grinding. A connecting frame 12 is rotatably connected to the housing 1. An operating rod 13 is connected to the connecting frame 12. The installation of the operating rod 13 makes it easier for the construction worker to perform grinding work on the wall surface at a higher position.

[0041] The power assembly 5 is installed on the other end face of the housing 1 and is used to drive the grinding disc 3 to rotate. The power assembly 5 includes a gearbox 51 and a drive motor 52. The gearbox 51 is installed on one end face of the housing 1. The output shaft of the gearbox 51 is connected to the rotating shaft of the grinding disc 3. The input end of the gearbox 51 is equipped with the drive motor 52.

[0042] A side grinding assembly 6 is installed on the side of the housing 1 and located inside the side cover 2. The side grinding assembly 6 forms a grinding surface perpendicular to the grinding disc 3, enabling the grinding and correction of wall corners. The side grinding assembly 6 can switch its working position according to the opening and closing state of the side cover 2. The side grinding assembly 6 includes a side grinding block 61, a connecting arm 62, and a telescopic rod 63. Sandpaper is installed on the surface of the side grinding block 61, and the side grinding block 61 has a cuboid structure. A transverse sliding groove is provided on the side grinding block 61, and the connecting arm 62 is slidably connected within the transverse sliding groove. The telescopic rod 63 is vertically fixed to the connecting arm 62. The telescopic rod 63 is vertically slidably connected to the connecting hole on the housing 1. The sliding of the telescopic rod 63 can switch the working state of the side grinding block 61. A tension spring 64 is installed on the telescopic rod 63. One end of the tension spring 64 is connected to the connecting arm 62, and the other end of the tension spring 64 is connected to the inner top surface of the housing 1. Its function is to pull the connecting arm 62 so that the connecting arm 62 drives the side grinding block 61 to retract, so that the side grinding block 61 switches to the non-working position, which facilitates the grinding disc 3 to quickly grind the central area of ​​the wall.

[0043] A reciprocating drive assembly 7 is installed inside the housing 1 and is used to drive the linear reciprocating motion of the side grinding assembly 6. The reciprocating drive assembly 7 includes a slide rail 71, a transverse plate 72, and a drive block 73. The slide rail 71 is installed in a rectangular groove in the housing 1.

It is slidably connected to the groove of the side grinding block 61; the housing 1 is provided with a bearing 74, and a drive disk 75 is connected to the bearing 74 through a rotating shaft. The drive disk 75 is rotatably connected to a connecting rod 76 at an eccentric position. The other end of the connecting rod 76 is rotatably connected to a connecting shaft on the transverse plate 72. The drive disk 75 is coaxially connected to a driven gear 77. The rotation of the drive disk 75 can drive the transverse plate 72 to slide linearly back and forth through the connecting rod 76, thereby driving the side grinding block 61 to move linearly back and forth.

[0044] A transmission control assembly 8 is installed inside the housing 1. The transmission control assembly 8 controls the operating state of the reciprocating drive assembly 7 according to the opening and closing state of the side cover 2. The transmission control assembly 8 includes a drive shaft 81, a drive gear 82, and a lever frame 83. The drive shaft 81 is rotatably connected to a rectangular groove in the housing 1. The cross-section of the drive shaft 81 is polygonal. The drive gear 82 has a corresponding polygonal hole in its center and is slidably connected to the drive shaft 81. The drive gear 82 can mesh with the driven gear 77. The connecting arm 62 is connected to... The device includes a drive frame 84, one end of which is connected to a lever frame 83. The lever frame 83 is used to move the drive gear 82 to slide on the drive shaft 81, so that the drive gear 82 meshes with or disengages from the driven gear 77. The drive shaft 81 is connected to the rotating shaft of the grinding disc 3 via a transmission belt 85. The operation of the side grinding component 6 can be controlled synchronously when the side cover 2 is opened or closed through the transmission control component 8. The operation is convenient and quick. Moreover, this device only uses one power component 5 to drive the grinding disc 3 and the side grinding component 6, which ensures that the device has a light weight and reduces production costs.

[0045] The working process of this invention is as follows:

[0046] When a large area of ​​the wall needs to be sanded quickly, the side cover 2 is closed, the drive motor 52 is started, and the drive motor 52 drives the sanding disc 3 to rotate through the gearbox 51. The sanding disc 3 drives the circular sandpaper 4 installed on its surface to rotate. The construction worker can use the hand lever 13 to bring the circular sandpaper 4 into contact with the wall and move it to achieve quick sanding of the middle area of ​​the wall.

[0047] When it is necessary to sand the inside corner of the wall, the side cover 2 is flipped over and rotated to the top of the housing 1. During this process, the side cover 2 presses the telescopic rod 63, causing the telescopic rod 63 to slide towards the sanding disc 3. The telescopic rod 63 drives the side sanding block 61 to extend through the connecting arm 62, so that the lower end surface of the side sanding block 61 is flush with the surface of the circular sandpaper 4, thereby switching the side sanding block 61 to the working state.

[0048] The movement of the connecting arm 62 drives the drive frame 84 to move synchronously. The drive frame 84 drives the actuating frame 83 to actuate the drive gear 82, causing the drive gear 82 to mesh with the driven gear 77. The rotating shaft of the grinding disc 3 drives the drive shaft 81 and the drive gear 82 to rotate through the transmission belt 85. This causes the drive gear 82 to drive the drive disc 75 to rotate through the driven gear 77. The drive disc 75 drives the transverse plate 72 to move linearly back and forth through the connecting rod 76. This causes the transverse plate 72 to drive the side grinding block 61 to move linearly back and forth through the drive block 73, thus achieving the grinding treatment of the adjacent inside corner of the wall. The front end face of the side grinding block 61 is perpendicular to the working surface of the grinding disc 3. This structure can provide support and limit for the grinding position of the grinding disc 3, preventing the grinding disc 3 from over-grinding the inside corner of the wall. Moreover, the perpendicular grinding surfaces can correct the inside corner of the wall, making the two adjacent surfaces at the inside corner of the wall more perpendicular.

[0049] After the inner corner of the wall is sanded, the sliding buckle 14 is used to disengage it from the slot on the side cover 2. The side cover 2 is rotated to close it and is fixed by the magnet 15. The side grinding block 61 retracts into the housing 1 under the action of the tension spring 64. The actuating frame 83 actuates the drive gear 82, causing the drive gear 82 to disengage from the driven gear 77. At this time, the sanding device quickly switches to the flat sanding mode, thus enabling rapid switching of sanding modes and providing convenience for wall sanding construction.
