Description

Technical Field

[0001] The utility model belongs to the technical field of sanding machines, and particularly relates to an environmentally friendly and dust-free surface sanding machine. Background Art

[0002] A sander is a machine used for surface treatment. It uses abrasive wheels and polishing wheels to create a smooth, flat, and lustrous finish. Sanders are also a common tool used in woodworking. For example, sanding and polishing wooden furniture and flooring can create a smooth, flat surface, enhancing their aesthetics and feel.

[0003] However, when the current sanding machine is in use, dust is mainly removed by the dust removal fan blades and dust removal pipes. Therefore, after long-term use, a large amount of dust is easily attached to the dust removal fan blades and the filter surface. A large amount of dust not only affects the rotation of the dust removal fan blades, but also causes the filter screen to be blocked, thereby affecting the dust collection effect of the dust removal fan blades. The present invention provides an environmentally friendly and dust-free surface sanding machine to alleviate the above-mentioned problems. Summary of the Invention

[0004] The utility model realizes the purpose of cleaning dust accumulated on the filter screen by cooperating with the cleaning components so that the cam knocks the surface of the filter screen plate and the rubber block beats the dust removal bag.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] The dust collecting box is connected to the dust collecting box by the dust collecting pipe, and the dust collecting box is cleaned by the dust collecting pipe.

[0007] Preferably, the cleaning component includes a second motor, and the second motor is installed on one side of the dust removal box, the output end of the second motor is connected to a rotating shaft, the outer sleeve of the rotating shaft is provided with a cam, and the surface of the partition close to the dust removal bag is symmetrically installed with a third motor, and the two third motors are respectively arranged on the upper and lower sides of the dust removal bag, the output end of the third motor is connected to a rotating rod, and the rotating rod is externally connected to a beating rod, and both ends of the beating rod are connected to rubber blocks.

[0008] Preferably, an installation groove is provided on the surface of the dust removal box away from the dust removal pipe, a fixing bracket is installed in the installation groove, a first motor is installed on the surface of the fixing bracket away from the dust removal pipe, and an output end of one side of the first motor passes through the fixing bracket and is connected to a fan blade.

[0009] Preferably, the inner walls of the dust removal box on both sides of the filter screen are provided with limiting grooves, both ends of the filter screen are connected with sliders, the inner walls of the limiting grooves are connected to guide rods, and the outer sleeve of the guide rods is provided with springs.

[0010] Preferably, a plurality of cams are arranged at equal intervals, and the outer ends of the cams are in contact with the surface of the filter plate, a plurality of beating rods are distributed at equal intervals, and the rubber block close to the dust bag side is in contact with the dust bag.

[0011] Compared with the prior art, the gain effect of the present invention is:

[0012] 1. By setting up structures such as dust removal bags, filter screens, activated carbon filters and fan blades, the air flowing into the dust removal box is driven by the fan blades and filtered through the filter screens, dust removal bags and activated carbon filters in turn, and finally discharged out of the device through the installation slot, thereby removing dust and impurities in the air as much as possible to avoid polluting the environment.

[0013] 2. By setting up a cleaning component, the second motor drives the rotating shaft and the cam to rotate together, so that the cam continuously knocks on the surface of the filter screen to prevent a large amount of dust from adhering to the surface of the filter screen, thereby affecting the dust suction effect of the fan blades; at the same time, the third motor drives the rotating rod to rotate, and the rotating rod drives the beating rod and the rubber block to rotate, so as to beat the dust bag and discharge the dust accumulated on its inner wall, thereby ensuring the dust removal effect of the device.

[0029] Working principle: When in use, the staff starts the first motor 12 to drive the fan blade 10 to rotate, driving the air flow inside the dust removal pipe 2 and the dust removal box 3. The dust generated by the sander body 1 during operation can be collected through the air flow inside the dust removal pipe 2. The staff can regularly take out the collection frame 14 for unified collection; then when the air flows inside the dust removal box 3, it first passes through the filter plate 7 to filter out the dust and large particles in the air, and then gradually enters the dust removal bag 6 to remove the fine particles suspended in the air, and finally passes through the activated carbon filter. The filter 9 absorbs and filters the air again, and finally discharges the purified air out of the device through the installation slot 19; after long-term use, the second motor 801 is started to operate, and the second motor 801 drives the rotating shaft 802 and the cam 803 to rotate together, so that the cam 803 continuously knocks on the surface of the filter plate 7, and at the same time the third motor 804 is started to drive the rotating rod 805 to rotate, and the rotating rod 805 drives the beating rod 806 and the rubber block 807 to rotate, so as to beat the dust bag 6 and discharge the dust accumulated on its inner wall, thereby ensuring the dust removal effect of the device.
