Description

Technical Field

[0001] This utility model belongs to the field of sandpaper machine technology, and specifically relates to a sandpaper machine for sanding wall putty. Background Technology

[0002] Applying putty is a method of interior decoration. Putty is applied to the wall to ensure a smooth surface. After the putty dries, it needs to be sanded with a sander to ensure its smoothness.

[0003] Existing wall putty sanders are operated by workers holding electric sanders. The motor drives the sandpaper disc or sandpaper belt to rotate or reciprocate at high speed to sand the dried putty layer. The abrasive particles of the sandpaper will evenly cut the putty surface, removing protrusions, joint marks and uneven areas. At the same time, some models are equipped with a dust collection device to absorb the dust generated during sanding and keep the working environment clean.

[0004] According to Chinese Patent Publication No. CN222227855U, a putty scraping machine for building decoration includes a motor, a motor housing located on the outer surface of the motor, and a handle mechanism fixedly installed on the side of the motor housing. A dust collection chamber is fixedly installed at the lower end of the motor housing, and a screw is provided at the lower end of the motor. A fan blade is connected through the middle section of the screw, and a grinding disc is connected to the bottom end of the screw.

[0005] However, according to the above-mentioned device and existing technology, when sanding wall putty, workers hold electric sanders and put the sanding disc in contact with the wall. Workers apply pressure to the electric sander to complete the sanding of the wall putty. Because maintaining pressure for a long time will cause arm fatigue and soreness, it will cause uneven pressure control between the sanding disc and the wall putty, ultimately causing wavy patterns on the putty surface, which will seriously affect the smoothness of the wall. Utility Model Content

[0006] In response to the problem in related technologies where workers maintain pressure for extended periods, resulting in uneven pressure control and wavy patterns on the putty surface, this utility model proposes a sander for sanding wall putty to overcome the aforementioned technical problems in existing related technologies.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model is a sander for sanding wall putty, including a sanding disc, a main body mechanism is provided on the surface of the sanding disc, a lifting mechanism is provided on the surface of the main body mechanism, a telescopic mechanism is provided at the output end of the lifting mechanism, and a buffer mechanism is provided on the surface of the sanding disc.

[0009] The main body mechanism is used to drive the sanding disc to sand the wall putty, the lifting mechanism is used to drive the telescopic mechanism to lift and lower, and the telescopic mechanism is used to drive the sanding disc to extend and retract.

[0010] Furthermore, the main body includes a housing, a protective shell is fixedly connected to the bottom of the housing, a motor is fixedly connected inside the housing, and handles and auxiliary handles are fixedly connected to the surface of the housing.

[0011] Furthermore, the bottom of each protective shell is movably connected with multiple ball bearings.

A small motor is fixedly connected to the surface of the housing, and the output shaft of the small motor is fixedly connected to the lead screw. A lifting plate is threadedly connected to the surface of the lead screw, and the lifting plate is slidably connected inside the housing.

[0013] Furthermore, the telescopic mechanism includes a connecting frame, one end of which is fixedly connected to the surface of the lifting plate. The connecting frame penetrates the housing and extends into the protective housing. The other end of the connecting frame is fixedly connected to a limit ring. A telescopic rod is rotatably connected inside the limit ring. A pin is fixedly connected to the output shaft of the motor. The pin is splinedly connected to one end of the telescopic rod.

[0014] Furthermore, the buffer mechanism includes a buffer rod, one end of which is fixedly mounted on the surface of the grinding disc, and the other end of which is fixedly connected to a spring. The buffer rod is splinedly connected to one end of the telescopic rod, and one end of the spring is fixedly connected inside the telescopic rod.

[0015] Furthermore, a telescopic hose is fixedly connected to the surface of the protective shell, a dust box is fixedly connected to one end of the telescopic hose, an air vent is rotatably connected to the surface of the dust box, a filter screen is fixedly connected inside the protective shell, and a fan is fixedly connected to the surface of the telescopic rod.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model presses the main body onto the wall putty surface, and controls the telescopic mechanism to rise and fall through the lifting mechanism. The telescopic mechanism drives the sanding disc to extend and retract within the main body, allowing the rotating sanding disc to sand the wall putty.

[0018] 2. This utility model uses the sanding disc to extend and retract, causing the sanding disc to drive the buffer rod to compress the spring inside the extension rod, thus buffering the sanding disc. Through the elastic force of the spring, the buffer rod slides inside the extension rod, and the buffer rod drives the sanding disc to keep in contact with the wall putty, dynamically compensating for the pressure applied when sanding the putty and avoiding over-sanding defects caused by improper manual operation.

[0029] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0030] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0031] Please see Figures 1-6 As shown, this utility model is a sander for sanding wall putty, including a sanding disc 1, a main body mechanism 2 is provided on the surface of the sanding disc 1, a lifting mechanism 3 is provided on the surface of the main body mechanism 2, a telescopic mechanism 4 is provided at the output end of the lifting mechanism 3, and a buffer mechanism 5 is provided on the surface of the sanding disc 1.

[0032] The main mechanism 2 is used to drive the sanding disc 1 to sand the wall putty, the lifting mechanism 3 is used to drive the telescopic mechanism 4 to lift and lower, and the telescopic mechanism 4 is used to drive the sanding disc 1 to extend and retract.

[0033] By connecting the main body 2 to the power supply, the sanding disc 1 is rotated and pressed onto the wall putty surface. The lifting mechanism 3 controls the telescopic mechanism 4 to rise and fall, causing the telescopic mechanism 4 to move the sanding disc 1 within the main body 2, allowing the sanding disc 1 to sand the wall putty. The sanding disc 1 maintains a constant sanding pressure, avoiding the wave-like patterns caused by pressure fluctuations in traditional operations. The floating design of the buffer mechanism 5 ensures that the sanding disc 1 can always contact the wall putty, avoiding over-sanding defects caused by improper manual operation.

[0034] By pressing the main body 2 onto the wall putty surface, the lifting mechanism 3 controls the telescopic mechanism 4 to rise and fall, causing the telescopic mechanism 4 to drive the sanding disc 1 to extend and retract within the main body 2. The rotating sanding disc 1 then sands the wall putty. During the sanding process, the height of the telescopic rod 403 is adjusted according to the required depth of sanding of the wall putty, thereby driving the sanding disc 1 to adjust the pressure between the wall putty and the sanding disc 1, maintaining a constant sanding pressure and avoiding the wavy patterns caused by pressure fluctuations in traditional operations.

[0035] In one embodiment, the main body 2 includes a housing 201, a protective shell 202 fixedly connected to the bottom of the housing 201, a motor 203 fixedly connected inside the housing 201, and handles 204 and auxiliary handles 205 fixedly connected to the surface of the housing 201.

[0036] Multiple ball bearings 206 are movably connected to the bottom of the protective shell 202.

[0037] The worker picks up handle 204 with one hand and auxiliary handle 205 with the other, bringing multiple ball bearings 206 on the surface of the protective shell 202 into contact with the wall surface to prevent the protective shell 202 from scratching the wall surface. At the same time, when the device moves, the multiple ball bearings 206 rotate, reducing the friction with the wall putty and improving the efficiency of the device's movement. The motor 203 is used to drive the sanding disc 1 to rotate.

[0038] In one embodiment, the lifting mechanism 3 includes a lead screw 301, which is rotatably connected to the surface of the housing 201. A small motor 302 is fixedly connected to the surface of the housing 201. The output shaft of the small motor 302 is fixedly connected to the lead screw 301. A lifting plate 303 is threadedly connected to the surface of the lead screw 301 and is slidably connected inside the housing 201.

[0039] The small motor 302 drives the lead screw 301 to rotate, causing the lead screw 301 to drive the lifting plate 303 to slide inside the housing 201, thus completing the lifting of the lifting plate 303.

[0040] In one embodiment, the telescopic mechanism 4 includes a connecting frame 401. One end of the connecting frame 401 is fixedly connected to the surface of the lifting plate 303. The connecting frame 401 passes through the housing 201 and extends into the protective housing 202. The other end of the connecting frame 401 is fixedly connected to a limiting ring 402. A telescopic rod 403 is rotatably connected inside the limiting ring 402. A pin 404 is fixedly connected to the output shaft of the motor 203. The pin 404 is splinedly connected to one end of the telescopic rod 403.

[0041] The lifting plate 303 drives the connecting frame 401 to rise and fall inside the housing 201. At the same time, the connecting frame 401 drives the limiting ring 402 to rise and fall. The limiting ring 402 drives the telescopic rod 403 to slide on the surface of the pin 404, increasing the length of the pin 404 and completing the extension and retraction of the telescopic rod 403. The motor 203 drives the pin 404 to rotate, causing the pin 404 to drive the telescopic rod 403, which is splinedly connected to the pin 404, to rotate. This spline connection is movable, so that when the pin 404 rotates, the telescopic rod 403 can also slide on the surface of the pin 404.

[0042] The connection between the limiting ring 402 and the telescopic rod 403 is a bearing connection, which optimizes the friction between the telescopic rod 403 and the limiting ring 402 when the rod rotates.

[0043] In one embodiment, the buffer mechanism 5 includes a buffer rod 501, one end of which is fixedly mounted on the surface of the grinding disc 1, and the other end of which is fixedly connected to a spring 502. The buffer rod 501 is splinedly connected to one end of the telescopic rod 403, and one end of the spring 502 is fixedly connected inside the telescopic rod 403.

[0044] When the grinding disc 1 extends or retracts, it causes the buffer rod 501 to compress the spring 502 inside the telescopic rod 403, thus buffering the grinding disc 1. Through the elastic force of the spring 502, the buffer rod 501 slides inside the telescopic rod 403. The buffer rod 501 drives the grinding disc 1 to keep in contact with the wall putty, dynamically compensating for the pressure applied when grinding the putty and avoiding over-grinding defects caused by improper manual operation.

[0045] In one embodiment, for the main body 2 described above, a telescopic hose 207 is fixedly connected to the surface of the protective shell 202, a dust box 208 is fixedly connected to one end of the telescopic hose 207, a ventilation net 209 is rotatably connected to the surface of the dust box 208, a filter screen 210 is fixedly connected inside the protective shell 202, and a fan 211 is fixedly connected to the surface of the telescopic rod 403.

[0046] The telescopic rod 403 rotates while driving the fan 211, creating a negative pressure inside the protective shell 202. This pressure attracts dust from the wall putty sanding process, allowing the dust to pass through the protective shell 202 and into the telescopic hose 207. The telescopic hose 207 is extendable, facilitating long-distance sanding. Large dust particles are filtered through the filter screen 210 fixedly connected inside the protective shell 202, preventing damage to the fan 211. The filtered dust then passes through the telescopic hose 207 into the dust box 208. The filtered air is then discharged through the air vent 209 on the surface of the dust box 208. The air vent 209 is removable for easy cleaning.

[0047] Through the above technical solution, 1. When sanding wall putty, the lifting plate 303 drives the connecting frame 401 to rise and fall inside the housing 201. At the same time, the connecting frame 401 drives the limiting ring 402 to rise and fall. The limiting ring 402 drives the telescopic rod 403 to slide on the surface of the pin 404, increasing the length of the pin 404 and completing the extension and retraction of the telescopic rod 403. The motor 203 drives the pin 404 to rotate, causing the pin 404 to drive the telescopic rod 403, which is splinedly connected to the pin 404, to rotate. 04 During rotation, the telescopic rod 403 can also slide on the surface of the pin 404. The telescopic rod 403 drives the buffer rod 501 to rotate, which in turn drives the sanding disc 1 to rotate. The rotating sanding disc 1 then sands the wall putty. During the sanding process, the height of the telescopic rod 403 is adjusted according to the required depth of sanding of the wall putty. This adjusts the pressure between the wall putty and the sanding disc 1, ensuring that the sanding disc 1 maintains a constant sanding pressure and avoiding the wavy patterns caused by pressure fluctuations in traditional operations.

[0048] 2. When the grinding disc 1 extends or retracts, it causes the buffer rod 501 to compress the spring 502 inside the telescopic rod 403, thus buffering the grinding disc 1. Through the elastic force of the spring 502, the buffer rod 501 slides inside the telescopic rod 403. The buffer rod 501 drives the grinding disc 1 to keep in contact with the wall putty, dynamically compensating for the pressure applied when grinding the putty and avoiding over-grinding defects caused by improper manual operation.
