Description

Technical Field

[0001] This utility model relates to the field of wall sanding technology, and in particular to a decorative wall sanding device. Background Technology

[0002] The sanding process after wall decoration is crucial. Its core function is to precisely eliminate various defects in the base layer through fine treatment of the wall surface, ensuring that the wall surface is smooth overall. At the same time, wall sanding can effectively enhance the adhesion between the subsequent coating and the base layer, preventing problems such as peeling and hollowing of the decorative layer from the root, and ultimately achieving the goal of improving the smoothness of the wall surface and optimizing the overall decorative effect.

[0003] Chinese utility model patent CN222114485U discloses an adjustable wall grinding device for building construction. This device has the following problems during use:

[0004] First, the sanding components can only sand vertical walls and cannot sand the ceiling.

[0005] Secondly, for large wall surfaces, the entire device needs to be moved frequently, resulting in low operating efficiency. Furthermore, when the machine is placed on an uneven construction site, the support base may sink into the bottom surface, causing instability and affecting the sanding accuracy.

[0006] Third, insufficient light during polishing may result in incomplete polishing and low precision. Utility Model Content

[0007] The purpose of this utility model is to provide a decorative wall sanding device. First, the sanding mechanism can be flipped, so it can sand vertical walls as well as top walls. Second, the sanding device can be manually held, which is convenient and flexible. Third, LED light strips are provided on both sides of the sanding component to eliminate blind spots and improve sanding accuracy.

[0008] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a decorative wall polishing device, including a support plate and an mounting plate located above the support plate, a support base is fixedly provided on one side of the support plate, the support base and the mounting plate are connected by a flipping mechanism, a polishing mechanism is provided on the mounting plate, a dust suction mechanism is connected to the side of the polishing mechanism near the support plate, and a handheld mechanism is fixedly provided below the support plate.

[0009] By adopting the above technical solution, the flipping mechanism can drive the mounting plate and the sanding mechanism to flip relative to the support plate, thereby changing the contact angle between the sanding mechanism and the wall surface, and adapting to the sanding needs of wall areas at different angles.

[0010] A further feature of this invention is that the flipping mechanism includes a connecting component and a first driving component for driving the movement of the connecting component.

[0011] A further feature of this invention is that the first drive assembly includes a first motor, the output end of which is fixedly connected to a worm gear, the worm gear meshing with a worm wheel, and a drive shaft for driving the connection assembly to move is fixedly inserted into the central hole of the worm wheel.

[0012] By adopting the above technical solution, when the first motor rotates, it will directly drive the worm to rotate synchronously, which in turn will drive the worm wheel to drive the transmission shaft to rotate synchronously.

[0013] The present invention is further configured such that: the connecting assembly includes a connecting seat fixedly disposed on the support base and a mounting seat fixedly disposed on the back of the mounting plate, and the support base and the mounting plate are rotatably connected by a first rotating shaft passing through the connecting seat and the mounting seat in sequence;

[0014] The connecting assembly also includes a rotating rod, one end of which is rotatably connected to the end of the drive shaft, and the other end of which is fixedly connected to one end of the support rod. The other end of the support rod is rotatably connected to a second rotating shaft, which passes through the mounting seat in the middle of the mounting plate.

[0015] By employing the above technical solution, when the support rod swings, it applies a pushing or pulling force to the mounting plate, forcing the mounting plate to flip around the first pivot point. Similar to the principle of a lever, with the first pivot point as the fulcrum, the force of the support rod causes the mounting plate to rotate around the fulcrum. The flipping of the mounting plate directly drives the grinding mechanism on it to change its angle until it reaches the desired position for wall construction.

[0016] A further feature of this invention is that the grinding mechanism includes a grinding disc mounted on a mounting plate and a second drive assembly for driving the grinding disc to rotate.

[0017] A further feature of this invention is that a cavity is provided between the grinding disc and the mounting plate, a central shaft that penetrates the mounting plate is fixedly connected to the center of the grinding disc, and the second drive assembly includes a second motor fixedly mounted on the back of the mounting plate, with the output shaft of the second motor and the central shaft connected by a belt drive.

[0018] By adopting the above technical solution, the second drive component can indirectly drive the grinding disc to rotate, thereby achieving the grinding effect on the wall. The cavity provides space and path for dust collection, improving the environmental friendliness and operational comfort of the device.

[0019] A further feature of this invention is that the dust collection mechanism includes a dust collection port located in the grinding disc area on the mounting plate, a dust outlet on the support plate, and the dust collection port and the dust outlet are connected by a telescopic hose. A connecting cavity is provided at the lower part of the dust collection port on the support plate.

[0020] By adopting the above technical solution, the dust collection mechanism can collect the dust generated during the polishing process.

[0021] A further feature of this invention is that the handheld mechanism includes a handheld tube fixedly connected to the connecting cavity.

[0022] By adopting the above technical solution, operators can flexibly control the movement trajectory, grinding speed, and pressure of the device by holding the handheld mechanism.

[0023] A further feature of this invention is that a lighting mechanism is fixedly provided on both sides of the mounting plate, and the lighting mechanism includes an LED light strip.

[0024] By adopting the above technical solution, the LED light strip can directly illuminate the contact point between the grinding disc and the wall, allowing operators to see the wall in real time, avoiding blind grinding and improving grinding efficiency.

[0025] The beneficial effects of this utility model are:

[0026] 1. The flipping mechanism can drive the mounting plate and the grinding mechanism to flip relative to the support plate, thereby changing the contact angle between the grinding mechanism and the wall surface, adapting to the grinding needs of wall areas at different angles, and improving the practicality and operational flexibility of the device.

[0027] 2. Operators can hold this device to flexibly control its movement trajectory, grinding speed, and pressure, thus improving the flexibility of the grinding work.

Detailed Implementation

[0035] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0036] This utility model embodiment provides a decorative wall polishing device, including a support plate 101 and an mounting plate 102 located above the support plate 101. A support base 103 is fixedly provided on one side of the support plate 101. The support base 103 and the mounting plate 102 are connected by a flipping mechanism 2. A polishing mechanism 3 is provided on the mounting plate 102. A dust suction mechanism 4 is connected to the side of the polishing mechanism 3 near the support plate 101. A handheld mechanism 5 is fixedly provided below the support plate 101.

[0037] Specifically, the flipping mechanism 2 can drive the mounting plate 102 and the sanding mechanism 3 to flip relative to the support plate 101, thereby changing the contact angle between the sanding mechanism 3 and the wall surface to adapt to the sanding needs of different wall surface areas.

[0038] Furthermore, the flipping mechanism 2 includes a connecting component 22 and a first driving component 21 for driving the movement of the connecting component 22.

[0039] Furthermore, the first drive assembly 21 includes a first motor 211 fixedly mounted on the support plate 101. The output end of the first motor 211 is fixedly connected to a worm gear 212, which meshes with a worm wheel 213. A drive shaft 214 for driving the connection assembly 22 is fixedly inserted into the center hole of the worm wheel 213.

[0040] Specifically, when the grinding angle needs to be adjusted, the first motor 211 is started, and the output end of the first motor 211 begins to rotate. The output end of the first motor 211 is fixedly connected to the worm 212. Therefore, when the first motor 211 rotates, it will directly drive the worm 212 to rotate synchronously. Since the worm 212 and the worm wheel 213 are engaged in transmission, the rotation of the worm 212 will drive the worm wheel 213 to drive the transmission shaft 214 to rotate synchronously.

[0041] Furthermore, the connecting assembly 22 includes a connecting seat 221 fixedly disposed on the support base 103 and a mounting seat 222 fixedly disposed on the back of the mounting plate 102. The support base 103 and the mounting plate 102 are rotatably connected by a first rotating shaft 223 passing through the connecting seat 221 and the mounting seat 222 in sequence.

[0042] The connecting assembly 22 also includes a rotating rod 224, one end of which is fixedly connected to the end of the drive shaft 214, and the other end of which is rotatably connected to one end of the support rod 225. The other end of the support rod 225 is rotatably connected to a second rotating shaft 226, which passes through the mounting seat 222 in the middle of the mounting plate 102.

[0043] Specifically, when the drive shaft 214 of the first drive assembly 21 rotates under the drive of the worm gear 213, the end of the drive shaft 214 will drive one end of the rotating rod 224 connected to it to move. The other end of the rotating rod 224 is rotatably connected to one end of the support rod 225. Therefore, the movement of the rotating rod 224 will push or pull the support rod 225.

[0044] The specific working process is as follows: when the rotating rod 224 pushes the mounting plate 102, the mounting plate 102 rotates around the first rotating shaft 223, causing the angle between the mounting plate 102 and the wall to gradually decrease, with a minimum angle of 0 degrees, which is suitable for vertical walls; when the rotating rod 224 pulls the mounting plate 102, the angle between the mounting plate 102 and the wall to gradually increase, with a maximum angle of 90 degrees, which is suitable for horizontal walls; the angle of the mounting plate 102 can be adjusted within the range of 0 to 90 degrees, so the grinding mechanism 3 can also be adjusted within the range of 0 to 90 degrees, which can adapt to the grinding needs of walls with different angles and improve the practicality and operational flexibility of the device.

[0045] The other end of the support rod 225 is rotatably connected to the mounting seat 222 in the middle of the mounting plate 102 via the second rotating shaft 226, and the mounting plate 102 is rotatably connected to the connecting seat 221 of the support base 103 via the first rotating shaft 223. The first rotating shaft 223 is the core rotation fulcrum of the mounting plate 102.

[0046] When the support rod 225 swings, it applies a pushing or pulling force to the mounting plate 102, forcing the mounting plate 102 to flip around the first pivot 223. Similar to the lever principle, with the first pivot 223 as the fulcrum, the force of the support rod 225 causes the mounting plate 102 to rotate around the fulcrum. The flipping of the mounting plate 102 directly drives the grinding mechanism 3 on it to change its angle until it reaches the position required for wall construction.

[0047] Furthermore, the polishing mechanism 3 includes a polishing disc 31 disposed on the mounting plate 102 and a second drive assembly 32 for driving the polishing disc 31 to rotate.

[0048] Furthermore, a cavity 33 is provided between the grinding disc 31 and the mounting plate 102, and a central shaft 34 that penetrates the mounting plate 102 is fixedly connected to the middle of the grinding disc 31. The central shaft 34 is rotatably connected to the mounting plate 102.

[0049] Furthermore, the second drive assembly 32 includes a second motor 35 fixedly mounted on the back of the mounting plate 102, and the output shaft of the second motor 35 and the central shaft 34 are connected by a belt 36.

[0050] When wall sanding is required, the second motor 35 of the second drive assembly 32 is started, and the output shaft of the second motor 35 begins to rotate. The output shaft of the second motor 35 is connected to the central shaft 34 of the sanding disc 31 via a belt 36. The rotation of the motor output shaft will drive the central shaft 34 to rotate synchronously through the friction of the belt 36. The middle part of the sanding disc 31 is fixedly connected to the central shaft 34. When the central shaft 34 rotates under the drive of the belt 36, it will directly drive the sanding disc 31 to rotate synchronously.

[0051] The cavity 33 between the grinding disc 31 and the mounting plate 102 is designed to accommodate the subsequent dust collection mechanism 4. A large amount of dust is generated when the wall is being sanded. Under negative pressure, the dust enters the cavity 33 through the fine holes on the grinding disc 31 and is then sucked into the dust collection mechanism 4. The cavity 33 provides space and path for dust collection, improving the environmental friendliness and operational comfort of the device.

[0052] During operation, the operator holds the rotating grinding disc 31 against the wall surface. Through the friction between the grinding wheel particles on the surface of the grinding disc 31 and the wall surface, the wall surface is smoothed and polished, which can remove wall protrusions, burrs and old coatings.

[0053] Furthermore, the dust collection mechanism 4 includes a dust collection port 41 opened on the mounting plate 102 and located in the area of ​​the grinding disc 31, and a dust outlet 42 opened on the support plate 101. The dust collection port 41 and the dust outlet 42 are connected by a telescopic hose 43. A connecting cavity 44 is correspondingly provided at the lower part of the dust collection port of the support plate 101, and a small vacuum cleaner is connected in the connecting cavity 44.

[0054] Specifically, when the sanding mechanism 3 is working, the sanding disc 31 rotates and rubs against the wall, generating a large amount of dust. This dust is mainly concentrated in the contact area between the sanding disc 31 and the wall. The suction port 41 is located on the mounting plate 102 and within the area of ​​the sanding disc 31. Under the suction force generated by the vacuum cleaner, the dust will be directly sucked into the suction port 41.

[0055] The suction port 41 and the dust outlet 42 on the support plate 101 are connected by a telescopic hose 43. When the device is working, the relative position of the mounting plate 102 and the support plate 101 will change. The telescopic hose 43 has the characteristics of being flexible and stretchable, which can adapt to the changes in angle and distance between the two, avoiding pipe breakage or obstruction of the mounting plate 102 due to rigid connection. At the same time, the internal channel of the hose can stably transport the dust sucked in by the suction port 41 to the dust outlet 42. The lower part of the dust outlet 42 is provided with a connecting cavity 44. The dust finally enters the external collection device through the connecting cavity 44 for centralized storage or subsequent processing.

[0056] It is worth noting that when the mounting plate 102 rotates around the first pivot 223, the angle between the support plate 101 and the mounting plate 102 changes from inclined to nearly horizontal. The distance between the support plate 101 and the mounting plate 102 is also slightly shortened due to the flipping. The telescopic hose 43 itself has the characteristics of being flexible and stretchable: when the mounting plate 102 flips upward, if the distance between the two is shortened, the telescopic hose 43 will naturally contract and fold due to the force, achieving reasonable retraction. If the angle changes during the flipping process, the telescopic hose 43 can bend flexibly with the angle and will not be stuck or broken due to rigidity. At the same time, the channel inside the telescopic hose 43 can still remain open in the bending and contracting state, and dust can be normally transported from the suction port 41 to the dust outlet 42 through the telescopic hose 43. Therefore, the dust collection operation will not be interrupted due to the deformation during the flipping.

[0057] Furthermore, the handheld mechanism 5 includes a handheld tube 51 fixedly connected to the connecting cavity 44, and a telescopic hose 43 connected below the handheld tube 51, which guides the dust to the collection bag 45.

[0058] Specifically, the connecting cavity 44 and the handheld cylinder 51 are fixedly connected by threads. The handheld cylinder 51 has an anti-slip texture design to fit the hand grip, and the operator can flexibly control the movement trajectory, grinding speed and pressure of the device by holding it.

[0059] Furthermore, lighting mechanisms 6 are fixedly installed on both sides of the mounting plate 102, and the lighting mechanisms 6 include LED light strips 61.

[0060] Specifically, the LED light strip 61 is existing technology. The LED light strip 61 is connected to the power supply system of the device through wires. It can be synchronously triggered to illuminate when the grinding mechanism 3 is working, or it can be controlled by an independent switch. Current flows through the light-emitting diode in the LED light strip 61, and the electrons and holes in the chip recombine to generate energy, which is released in the form of visible light to achieve light emission.

[0061] Wall sanding, especially in indoor corners and ceilings, often makes it difficult for operators to see the sanding effect due to insufficient natural light or the sanding disc 31 blocking the light. However, the LED light strips 61 on both sides of the mounting plate 102 can directly illuminate the contact point between the sanding disc 31 and the wall, allowing operators to see the flatness of the wall and whether there are any residual impurities in real time. This enables them to accurately adjust the sanding pressure, speed, or path, avoiding blind sanding and improving sanding efficiency.

[0062] The above describes the basic principles, main features, and advantages of this utility model. The standard parts used in this utility model can all be purchased from the market, and the irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art, which will not be described in detail here.

The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.
