Description

Technical Field

[0001] This utility model relates to the field of sanding machines, and in particular to a multi-functional sanding machine. Background Technology

[0002] A sander is a power tool widely used in some industries. It smooths the surface of different materials by attaching sandpaper to a rotating motor, generating friction. Most sanders are electric, but some are powered by compressed air. Traditional sanders mainly consist of a drive roller, a motor, a conveyor belt, and sandpaper. Before starting work, the motor is turned on, and the conveyor belt moves the object forward. The drive roller drives the sandpaper to sand the object. This method cannot be adjusted according to the thickness of the object, and different sanders need to be used for sanding, resulting in low efficiency. During operation, the sanding debris affects the cleanliness of the working environment and may directly harm the health of the workers.

[0003] Therefore, those skilled in the art have provided a multifunctional sander to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-functional sander. Before operation, the corresponding switch is activated via the control panel. During operation, an electric telescopic rod drives sliding blocks on both sides of the first fixed plate to slide within the lifting groove. This allows the conveyor assembly to adjust the space according to the thickness of A1-grade fireproof and flame-retardant boards, solving the problem of needing to change sanders of different models when sanding wood of varying thicknesses. Multiple fixed protrusions on the conveyor belt prevent shaking during surface sanding. The sanding process utilizes both coarse and fine sanding belts to achieve a smoother and more uniform surface. A large amount of debris is generated during sanding. Three suction heads (number one, number two, and number three) are positioned at the inlet, center, and outlet, respectively. The suction motor draws the debris into the suction pipe and into the dust collection box, solving the problem of debris affecting the working environment and harming the health of workers.

A fine sand belt is fixedly installed on the outer wall of the second driving roller, the second driven roller and the second tensioning wheel.

[0006] Furthermore, the conveying assembly includes a second fixing plate, the lower end of which is fixedly mounted on the output end of the electric telescopic rod, and the upper end of which is fixedly mounted on a conveyor belt via a mounting bracket. Four sliding blocks are fixedly mounted on the front and rear sides of the second fixing plate and the conveyor belt.

[0007] Furthermore, a dust removal assembly is fixedly installed at the lower end of the inner wall on one side of the outer shell of the box. The dust removal assembly includes a dust collection box, a second suction pipe, and a third suction pipe. At the lower end of the outer wall on one side of the dust collection box, a motor box is fixedly installed at the center of one end of the dust collection box. A suction motor is fixedly installed at the center of the motor box. A fan blade is fixedly installed at the output end of the suction motor. A dustproof net is fixedly installed at one end of the fan blade. A first suction pipe is fixedly installed at the center of the upper surface of the dust collection box. The first suction pipe passes through the center of the upper surface of the outer shell of the box. A first suction head is fixedly connected to one end of the first suction pipe.

[0008] Furthermore, one end of the second suction pipe is fixedly connected to the first suction pipe, and the other end is inserted through the center of the upper part of the box shell near the end of one end and connected to the second suction head. One end of the third suction pipe is fixedly connected to the first suction pipe, and the other end is inserted through the center of the upper part of the box shell near the end of one end and connected to the third suction head.

[0009] Furthermore, the four sliding blocks are slidably disposed within the four lifting grooves, and multiple friction protrusions are fixedly disposed on the outer wall surface of the conveyor belt.

[0010] Furthermore, the first suction head is fixedly installed in the gap between the fine sand belt and the coarse sand belt and at the upper end of the conveying component; the second suction head is fixedly installed in the gap between the inner wall of one end of the box shell and the outer wall of one end of the fine sand belt; and the third suction head is fixedly installed in the gap between the inner wall of one end of the box shell and the coarse sand belt.

[0013] This utility model has the following beneficial effects: This utility model proposes a multi-functional sander. Before operation, the control panel is used to turn on the corresponding control switch to start the machine. Before turning on the working switch, the electric telescopic rod is used to adjust the space for sanding according to the thickness of the A1-grade flame-retardant board and protective board. Turning on the conveyor belt switch utilizes multiple friction protrusions on the conveyor belt to prevent the wood board from shaking during sanding. During long-term sanding, the use of tension rollers No. 1 and No. 2 can prevent the coarse and fine sanding belts from becoming loose, resulting in uneven sanding. During the sanding process, a dust extraction motor drives dust extraction heads No. 1, No. 2, and No. 3 to suck up the sanding debris into various pipes and into the dust collection box. This solves the problem of a large amount of debris generated during sanding affecting the working environment and endangering the health of workers. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figure 1 , Figure 2 , Figure 3This utility model provides an embodiment of a multi-functional sander, including a housing 1, which includes a housing shell 101. The housing shell 101 is made of stainless steel, which is strong and corrosion-resistant. Four lifting slots 102 are fixedly installed on the front and back sides of the outer wall of the housing shell 101, near the lower end. A first fixing plate 103 is fixedly installed at the lower end of the housing shell 101. The first fixing plate 103 is made of stainless steel, which is strong and can withstand pressure well. An electric telescopic rod 5 is fixedly installed at the center of the upper surface of the first fixing plate 103. A conveying assembly 3 is installed inside the housing shell 101 near the center and fixed to the upper end of the electric telescopic rod 5. A first driving roller 6 is fixedly installed on one inner wall of the housing shell 101. The first driving roller 6 is made of steel plate and has been quenched to make it more stable and robust. A second lifting roller 6 is fixedly installed on the inner wall of the housing shell 101 above the first driving roller 6. A tensioning wheel 8 is fixedly installed on the inner wall of the first active roller 6 and the first driven roller 7, near the end of the outer shell 101. The tensioning wheel 8 can prevent the abrasive belt from becoming loose during grinding. A coarse abrasive belt 9 is fixedly installed on the outer wall of the first active roller 6, the first driven roller 7, and the tensioning wheel 8. The coarse abrasive belt 9 is made of micron-sized crystals and has zirconium dioxide material added inside, which has high wear resistance and good effect. A second active roller 10 is fixedly installed on the other side of the inner wall of the outer shell 101. A second driven roller 11 is fixedly installed on the upper end of the second active roller 10. A tensioning wheel 12 is fixedly installed on the inner wall of the second active roller 10 and the second driven roller 11, near the end of the outer shell 101. A fine abrasive belt 13 is fixedly installed on the outer wall of the second active roller 10, the second driven roller 11, and the second tensioning wheel 12. The fine abrasive belt 13 is made of micron-sized crystals and has zirconium dioxide material added inside, which is more wear-resistant and has high precision.

[0018] Specifically, during operation, the electric telescopic rod 5 drives the conveyor assembly 3 to adjust the appropriate sanding space according to the thickness, solving the problem of low work efficiency caused by the need to change different sanders for objects of different thicknesses in traditional sanders. During sanding, the multiple friction protrusions 304 on the conveyor belt 302 of the conveyor assembly 3 can prevent the object from shaking during sanding, which would lead to poor sanding results. During sanding, the coarse sanding belt 9 and the fine sanding belt 13 are used for double sanding to make the surface smoother and more uniform. During the sanding process, the first tensioning wheel 8 and the second tensioning wheel 12 can prevent the coarse sanding belt 9 and the fine sanding belt 13 from becoming loose due to long-term sanding, which would lead to inconsistent sanding surfaces and poor quality.

[0019] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4The conveying assembly 3 includes a second fixing plate 301. The second fixing plate 301 is made of stainless steel, which has high load-bearing capacity and cost-effectiveness. The lower end of the second fixing plate 301 is fixedly mounted on the output end of the electric telescopic rod 5. The upper end of the second fixing plate 301 is fixed to the conveyor belt 302 by a mounting bracket. Four sliding blocks 303 are fixedly mounted on the front and rear positions of both sides of the second fixing plate 301 and the conveyor belt 302. The four sliding blocks 303 are slidably mounted in the four lifting grooves 102. Multiple friction protrusions 304 are fixedly mounted on the outer wall surface of the conveyor belt 302. The multiple friction protrusions 304 are made of rubber to prevent the A1-grade fireproof board and flame-retardant board on the conveyor belt 302 from affecting its fireproof performance and causing shaking.

[0020] Specifically, before starting work, the electric telescopic rod 5 is used to push the second fixed plate 301 to drive the four sliding blocks 303 to slide in the four lifting slots 102. After the adjustment is completed, the conveyor belt 302 is used to move the A1 grade flame retardant board and protective board through multiple friction protrusions 304 on the surface to prevent shaking during the sanding process, which would lead to poor sanding effect. This solves the problem that traditional sanders cannot adjust the appropriate sanding space according to the thickness of the object.

[0021] Reference Figure 1 , Figure 3 , Figure 4 , Figure 5A dust removal assembly 4 is fixedly installed at the lower end of the inner wall of one side of the outer shell 101. The dust removal assembly 4 includes a dust collection box 401, a second suction pipe 408, and a third suction pipe 410. The dust collection box 401 is fixedly installed at the lower end of the outer wall of one side of the outer shell 101. The dust collection box 401 is made of polypropylene plastic, which is corrosion-resistant, high-temperature resistant, and not easily damaged. A motor box 402 is fixedly installed at the center of one end of the dust collection box 401. A vacuum motor 403 is fixedly installed at the center of the motor box 402. A fan blade 404 is fixedly installed at the output end of the vacuum motor 403. A dustproof net 405 is fixedly installed at one end of the fan blade 404. The dustproof net 405 is made of polypropylene fiber, which is waterproof, high-temperature resistant, and moisture-resistant. It can prevent debris from entering the motor box 402 and affecting the operation of the vacuum motor 403. The upper surface of the dust collection box 401 is... A first suction pipe 406 is fixedly installed at the center of the box shell 101. The first suction pipe 406 is made of plastic and is resistant to high temperature and corrosion. The first suction pipe 406 passes through the center of the upper surface of the box shell 101. One end of the first suction pipe 406 is fixedly connected to a first suction head 407. The end of the first suction head 407 near the conveyor belt 302 is provided with multiple filter holes to prevent some larger debris from entering and causing blockage. One end of the second suction pipe 408 is fixedly connected to the first suction pipe 406, and the other end passes through the center of the upper surface of the box shell 101 near the end of one end and is connected to a second suction head 409. One end of the third suction pipe 410 is fixedly connected to the first suction pipe 406, and the other end passes through the center of the upper surface of the box shell 101 near the end of one end and is connected to a third suction head 411.

[0022] Specifically, at the start of the polishing process, the corresponding switch is turned on via the control panel 2 to activate the vacuum motor 403. During operation, the first vacuum head 407, the second vacuum head 409, and the third vacuum head 411 collect the polishing debris and draw it into the corresponding pipes. Finally, the debris converges into the first vacuum pipe 406 and falls into the dust collection box 401. This solves the problem of a large amount of debris being generated during polishing, which affects the working environment and endangers the health of the workers. The dustproof net 405 inside the dust collection box 401 prevents the debris from entering the motor housing 402 and affecting its operation.

[0023] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4The first suction head 407 is fixedly installed in the gap between the fine sand belt 13 and the coarse sand belt 9 and at the upper end of the conveyor assembly 3. The second suction head 409 is fixedly installed in the gap between the inner wall of one end of the box shell 101 and the outer wall of one end of the fine sand belt 13. The third suction head 411 is fixedly installed in the gap between the inner wall of one end of the box shell 101 and the coarse sand belt 9. Four fixed legs 14 are fixedly installed at the lower end of the box shell 101. The four fixed legs 14 are fixedly installed at the four corners of the lower surface of the first fixed plate 103. The four fixed legs 14 are made of silicone material at the ground contact position to prevent them from moving during operation. A control panel 2 is fixedly installed on one side of the outer wall of the box shell 101 near the center.

[0024] Specifically, when performing debris removal, the first suction head 407, fixed in the gap between the fine sand belt 13 and the coarse sand belt 9, the second suction head 409, fixed in the gap between the inner wall of one end of the box shell 101 and the outer wall of one end of the fine sand belt 13, and the third suction head 411, fixed in the gap between the inner wall of one end of the box shell 101 and the coarse sand belt 9, are used to remove debris from three directions. This method can effectively prevent debris from entering the workers' bodies and affecting their health. Before starting work, the four fixed legs 14 are used to place the debris on a relatively flat surface. The silicone sealant adheres to the ground to prevent the debris from moving during operation.

[0025] Working principle: Before operation, the machine is fixed to the ground using four fixed legs 14. During operation, the corresponding switches are turned on using the control panel 2. Turning on the electric telescopic rod 5 drives the second fixed plate 301 and the four sliding blocks 303 on the conveyor belt 302 to slide within the four lifting slots 102. This solves the problem of traditional sanders not being able to adjust the space appropriately according to the different thicknesses of A1-grade flame-retardant and fireproof boards. Turning on the switches of the first active roller 6 and the second active roller 10 drives the coarse sanding belt 9 and fine sanding belt 13 on the outer walls of the first driven roller 7 and the second driven roller 11 for sanding. Multiple friction protrusions 304 on the conveyor belt 302 prevent friction during sanding. If shaking occurs, the A1-grade flame-retardant board is transported to the grinding position by the conveyor belt 302. The coarse sanding belt 9 and the fine sanding belt 13 are used for double grinding to make the surface smoother and more uniform. During long-term grinding, the No. 1 tensioning wheel 8 and the No. 2 tensioning wheel 12 are used to prevent the coarse sanding belt 9 and the fine sanding belt 13 from loosening, which would lead to poor grinding effect. When grinding, the dust collection motor 403 is turned on, and the dust collection head in three directions is used to suck up the grinding debris and transfer it to each dust collection pipe. Finally, it flows into the No. 1 dust collection pipe 406 and falls into the dust collection box 401. This solves the problem of a large amount of debris generated during grinding affecting the working environment and endangering the health of the workers.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
