Description

Technical Field

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

[0002] A sander is an electric tool used to sand and smooth the surface of workpieces made of various materials. It is widely used in industries such as construction, home decoration, and furniture manufacturing. It is used for fine grinding and sanding of wooden structural parts and sanding and smoothing of wall decorations. It can also be used for rust removal on metal surfaces in automobiles, shipbuilding, and other industries.

[0003] The working principle of a sander is to use a drive system that drives a transmission device via a motor to make the grinding wheel and sanding belt rotate and reciprocate at high speed. The grinding wheel system includes the grinding wheel and the grinding wheel support device, which is used to grind the surface of the workpiece. In long-term use and observation, it has been found that existing sanders generate a lot of debris and dust when sanding workpieces such as sheet metal, which leads to pollution and affects the health of operators. Therefore, we propose a sander waste cleaning device. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a sanding machine waste cleaning device, which has the advantage of reducing the amount of debris and dust generated during the sanding process that is scattered to the outside.

[0005] The technical solution of this utility model is as follows: it includes a conveyor belt, a lower box fixed to the bottom of the conveyor belt, an upper box fixed to the top of the conveyor belt, a sanding and polishing mechanism inside the upper box, a storage box and an air pump fixed to the bottom of the inner side wall of the lower box, the air pump and the storage box being connected by a pipe, a filter screen being installed inside the storage box, and a pair of first air inlets fixed to the side wall of the upper box, the first air inlets being connected to the storage box by a pipe. Through the above structure, the storage box is connected to the air pump and the first air inlets, which can suck out and collect the debris and dust generated during the sanding of the board from the upper box, thereby reducing the dispersion of dust and debris, which could lead to pollution and affect the health of the operators.

[0006] In a further technical solution, two sets of reciprocating lead screws are rotatably connected to the inner side wall of the upper box. A brush plate is slidably connected to the middle of the reciprocating lead screw, and the brush plate contacts the surface of the first air intake hood. A motor is fixed to the inner side wall of the upper box, and the reciprocating lead screw and the motor are driven by a synchronous belt. With the above structure, the reciprocating lead screw, brush plate and motor can facilitate the cleaning of the surface of the first air intake hood, so as to reduce the adhesion of debris and dust to the air intake of the first air intake hood and the blockage caused by it.

[0007] In a further technical solution, an electric push rod is fixedly connected to the side wall of the upper box, and a second air inlet hood is fixedly connected to the bottom of the electric push rod. The second air inlet hood is connected to the storage box through a hose. With the above structure, the electric push rod and the second air inlet hood can be conveniently removed and collected from the surface of the board, so as to reduce the situation where residual debris on the board falls into the workshop and causes pollution. At the same time, the electric push rod drives the second air inlet hood to move, which can adapt to boards of different thicknesses, thereby improving the applicability during use.

[0008] In a further technical solution, the side wall of the storage bin is provided with an opening, and a collection box is slidably fitted inside the opening. The side wall of the lower bin is provided with a discharge port, which is correspondingly arranged with the collection box. Through the above structure, the opening, the collection box, and the discharge port are provided to facilitate the removal of debris collected in the storage bin, thereby improving the convenience of use.

[0009] In a further technical solution, multiple damping spring shock absorbers are fixedly connected to the top of the inner side wall of the lower housing. A fixing plate is fixedly connected to the top of the multiple damping spring shock absorbers. The fixing plate is fixed to the bottom of the air pump. Through the above structure, the damping spring shock absorbers and the fixing plate can reduce the vibration of the air pump during operation, thereby reducing the possibility of excessive vibration of the air pump, which could lead to loosening and damage of its internal parts, and thus improving the service life of the air pump.

[0010] In a further technical solution, multiple bristles are fixed to the bottom of the second air intake hood, and the multiple bristles surround the bottom of the second air intake hood to form an opening. Through the above structure, the bristles are connected to the second air intake hood, which can improve the absorption effect of the second air intake hood on debris by sweeping and wrapping the debris under the second air intake hood.

[0011] The beneficial effects of this utility model are:

[0012] 1. A storage tank is connected to an air pump and a first air inlet hood. This allows for the extraction and collection of debris and dust generated during the grinding of the sheet metal, reducing dust and debris dispersion and minimizing pollution and health risks to operators.

[0013] 2. The electric actuator and the second air intake hood are installed to facilitate the removal and collection of debris remaining on the surface of the board, thereby reducing the possibility of debris falling into the workshop and causing pollution.

[0021] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0022] Example:

[0023] like Figures 1-4 As shown, the system includes a conveyor belt 1, a lower housing 11 fixed to the bottom of the conveyor belt 1, an upper housing 12 fixed to the top of the conveyor belt 1, a sanding and polishing mechanism inside the upper housing 12, a storage tank 13 and an air pump 14 fixed to the bottom of the inner side wall of the lower housing 11, the air pump 14 and the storage tank 13 being connected by a pipe, a filter screen being installed inside the storage tank 13, and a pair of first air inlets 15 fixed to the side wall of the upper housing 12, the first air inlets 15 being connected to the storage tank 13 by a pipe.

[0024] The working principle of the above technical solution is as follows:

[0025] The conveyor belt 1 is started, and the sheet is placed on the surface of the conveyor belt 1. The sheet is then conveyed to the upper box 12 and sanded by the sanding and polishing mechanism. During the sanding of the sheet, a lot of debris and dust are generated. At this time, the air pump 14 is started to drive the airflow from the upper box 12 into the first air intake hood 15. The debris and dust generated during the sanding can be drawn into the first air intake hood 15 and then into the storage box 13, where they are filtered out and collected by the filter screen. Through the above structure, the storage box 13 is connected to the air pump 14 and the first air intake hood 15. During the sanding of the sheet, the debris and dust generated can be sucked out and collected from the upper box 12, thereby reducing the dispersion of dust and debris, which may cause pollution and affect the health of the operators.

[0026] In another embodiment, such as Figures 2-3 As shown, two sets of reciprocating lead screws 2 are rotatably connected to the inner side wall of the upper housing 12. A brush plate 21 is slidably connected to the middle of the reciprocating lead screw 2. The brush plate 21 is in contact with the surface of the first air intake hood 15. A motor 22 is fixedly connected to the inner side wall of the upper housing 12. The reciprocating lead screw 2 and the motor 22 are driven by a synchronous belt.

[0027] When debris and dust enter the first air intake hood 15, some debris may adhere to the air intake of the first air intake hood 15. At this time, starting the motor 22 can drive the reciprocating screws 2 on both sides to rotate. The reciprocating screws 2 will drive the brush plate 21 to move back and forth. At this time, the brush plate 21 contacts the surface of the first air intake hood 15 and can clean its air intake. Through the above structure, by setting the reciprocating screws 2, brush plate 21 and motor 22, it is convenient to clean the surface of the first air intake hood 15, so as to reduce the adhesion of debris and dust to the air intake of the first air intake hood 15 and the blockage caused by it.

[0028] In another embodiment, such as Figure 1 and Figure 5 As shown, an electric push rod 3 is fixedly connected to the side wall of the upper box 12, and a second air inlet hood 31 is fixedly connected to the bottom of the electric push rod 3. The second air inlet hood 31 is connected to the storage box 13 through a hose.

[0029] After the board is polished, the output will be directed towards the second air intake hood 31. At this time, the electric push rod 3 is activated to stretch and move the second air intake hood 31 downward. When the second air intake hood 31 is close to the top of the board, the stretching of the electric push rod 3 is stopped. When the air pump 14 is pumping air, the airflow will also enter through the second air intake hood 31. At this time, the second air intake hood 31 can suck away the debris remaining on the surface of the board, and then it will also enter the storage box 13 for collection. Through the above structure, the electric push rod 3 and the second air intake hood 31 can facilitate the removal and collection of debris remaining on the surface of the board, so as to reduce the situation of debris remaining on the board falling into the workshop and causing pollution. At the same time, the electric push rod 3 drives the second air intake hood 31 to move, which can adapt to boards of different thicknesses, thereby improving the applicability during use.

[0030] In another embodiment, such as Figure 1 and Figure 4 As shown, the storage box 13 has an opening 4 on its side wall, and a collection box 41 is slidably fitted inside the opening 4. The lower box 11 has an outlet 42 on its side wall, and the outlet 42 is correspondingly set with the collection box 41.

[0031] After the debris enters the storage bin 13, it will fall into the collection box 41 inside the storage bin 13. After collection is completed, the collection box 41 can be pulled out and then moved out of the lower box 11 from the discharge port 42. The debris collected by the collection box 41 can be poured out and then the collection box 41 can be returned to the storage bin 13. Through the above structure, the opening 4, the collection box 41 and the discharge port 42 are set to facilitate the removal of debris collected in the storage bin 13, thereby improving the convenience of use.

[0032] In another embodiment, such as Figure 4 As shown, multiple damping spring shock absorbers 5 are fixedly connected to the top of the inner side wall of the lower housing 11, and a fixing plate 51 is fixedly connected to the top of the multiple damping spring shock absorbers 5. The fixing plate 51 is fixedly connected to the bottom of the air pump 14.

[0033] When the air pump 14 is running, it will generate a lot of vibration. At this time, multiple damping spring shock absorbers 5 at the bottom of the air pump 14 will continuously contract and rebound to achieve the function of buffering and damping vibration. Through the above structure, the damping spring shock absorbers 5 and the fixing plate 51 are set to reduce the vibration of the air pump 14 during operation, so as to reduce the situation where the air pump 14 vibrates too much, causing the internal parts to loosen and be damaged, thereby improving the service life of the air pump 14.

[0034] In another embodiment, such as Figure 5 As shown, a plurality of bristles 6 are fixed to the bottom of the second air intake shroud 31, and the plurality of bristles 6 surround the bottom of the second air intake shroud 31 to form an opening.

[0035] When the second air intake hood 31 approaches the surface of the board, the bristles 6 will come into contact with the surface of the board. At this time, the bristles 6 have an open structure on three sides around the bottom of the second air intake hood 31. While cleaning the surface of the board, the bristles 6 block the debris under the second air intake hood 31, so that they can be better absorbed by the second air intake hood 31. With the above structure, the bristles 6 are connected to the second air intake hood 31. By cleaning the debris and wrapping it under the second air intake hood 31, the absorption effect of the second air intake hood 31 on the debris can be improved.

[0036] In another embodiment, such as Figure 2 As shown, the surface of the conveyor belt 1 is covered with a rubber layer 7, and the surface of the rubber layer 7 is provided with anti-slip grooves.

[0037] When the sheet material is conveyed on the surface of the conveyor belt 1, it will come into contact with the rubber layer 7 on its surface. Through the above structure, the rubber layer 7 can increase the friction between the conveyor belt 1 and the sheet material, and at the same time reduce the wear between the conveyor belt 1 and the sheet material.

[0038] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
