Description

Technical Field

[0001] The utility model relates to the technical field of sanding machines, in particular to a sanding machine with a dust suction structure. Background Art

[0002] In the field of power tools, sanders are a commonly used power tool, usually used to polish the surface of wood products. Sanders mainly include a motor, a transmission assembly and a base plate. The transmission assembly includes an eccentric piece. In the working state, the transmission assembly transmits the rotational motion of the motor to the eccentric motion of the base plate. Sandpaper or other polishing parts are installed on the lower surface of the base plate. The polishing parts move with the base plate to grind and polish the processed surface.

[0003] However, during the actual use of the above-mentioned sanding machine, a large amount of dust will be generated due to the grinding of the surface of the object. In the prior art, the sanding machine is usually provided with a suction port on the bottom plate, but only the dust near the suction port can be sucked, while the dust located at the edge of the bottom plate cannot be collected. This part of the dust will escape into the air, which has a negative impact on the environment and the health of the operator. In view of this, we propose a sanding machine with a dust suction structure. Utility Model Content

[0004] The utility model aims to provide a sanding machine with a dust suction structure to solve the problems raised in the above background technology.

[0005] To achieve the above object, the utility model provides the following technical solution: a sanding machine with a dust suction structure, comprising a sanding machine body, a side wall of the sanding machine body is provided with a dust suction component, and the dust suction component comprises:

[0006] A bending portion, wherein the outer wall of the sanding machine body is fixedly connected with a horizontal portion, and an end of the horizontal portion away from the sanding machine body is fixedly connected with the bending portion;

[0007] An annular airbag, wherein the bending portion and the annular airbag are sleeved together;

[0008] The abutment portion, the bottom of the bending portion is fixedly connected with a vertical portion, one end of the vertical portion away from the bending portion is fixedly connected with the abutment portion, and the bottom end surface of the abutment portion is provided with anti-slip grooves;

[0009] The side wall of the vertical part of the air suction pipe is fixedly connected with an air pump, and the air outlet of the air pump is fixedly connected with the air suction pipe.

[0010] Preferably, a mounting ring is fixedly connected to the outer wall of the vertical portion, and a brush is fixedly connected to the bottom end surface of the mounting ring.

[0011] Preferably, the annular airbag abuts against the inner top of the bending portion, and the annular airbag abuts against the bottom end face of the horizontal portion. The outer wall of the annular airbag is made of elastic material. The annular airbag pushes the bending portion and the vertical portion, thereby making the abutting portion abut against the polished surface.

[0012] Preferably, the anti-slip pattern includes horizontal patterns and vertical patterns, and the horizontal patterns and vertical patterns are cross-distributed at 90°.

[0013] Preferably, the abutment portion is provided in a triangular shape at one end away from the vertical portion, and the hypotenuse of the triangle abuts against the polishing surface. The triangular arrangement enables the abutment portion to shovel up dust, and there is no dead angle between the abutment portion and the polishing surface, thereby facilitating the air pump to suck dust.

[0014] Preferably, the brushes are arranged in a number of groups, and the brushes in the groups are arranged in a ring shape at equal intervals on the bottom end surface of the mounting ring.

[0015] Compared with the prior art, the utility model provides a sanding machine with a dust suction structure, which has the following beneficial effects:

[0016] 1. The sanding machine with a dust suction structure is provided with a horizontal part, a bending part, a vertical part, a contact part, an anti-skid pattern, and an annular airbag. The annular airbag elastically pushes the contact part to tightly contact the grinding surface, and then presses the bottom plate of the sanding machine body to contact the grinding surface. The dust generated by grinding is sucked out of the sanding machine body by the suction pipe and the air pump. The contact part is arranged in a triangular shape at one end away from the vertical part. The hypotenuse of the triangle contacts the grinding surface, so that the contact part can shovel up dust. There is no dead angle between the contact part and the grinding surface, which is convenient for the air pump to suck dust. The ground of the contact part is provided with anti-skid patterns. The anti-skid patterns increase the friction between the dust suction component and the grinding surface, thereby limiting the sanding machine body, reducing the torque generated on the operator's hand when the sanding machine body is rotated for grinding, and thereby improving the comfort of the sanding machine body operation.

[0017] 2. The sanding machine with a dust suction structure is provided with a mounting ring and a brush. When part of the dust leaks out from the gap between the abutting part and the polishing surface due to the unevenness of the polishing surface, the brush is always in contact with the polishing surface. The brush can effectively prevent this part of the dust from continuing to spread into the environment, thereby improving the dust control effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] like Figure 1-Figure 3 As shown, the utility model provides a technical solution: a sanding machine with a dust suction structure, including a sanding machine body 1, a side wall of the sanding machine body 1 is provided with a dust suction component 2, the dust suction component 2 includes a horizontal portion 21, a bending portion 22, a vertical portion 23, an abutment portion 24, an anti-slip pattern 25, an annular airbag 26, a mounting ring 27, a brush 28, an air suction pipe 3 and an air pump 4.

[0023] In one embodiment of the utility model, the outer wall of the sanding machine body 1 is fixedly connected with a horizontal part 21, and the end of the horizontal part 21 away from the sanding machine body 1 is fixedly connected with a bending part 22, and the bending part 22 is sleeved with an annular airbag 26, and the annular airbag 26 abuts against the inner top of the bending part 22, and the annular airbag 26 abuts against the bottom end surface of the horizontal part 21. The material of the outer wall of the annular airbag 26 is an elastic material, and the annular airbag 26 pushes the bending part 22 and the vertical part 23, so that the abutting part 24 abuts against the grinding surface, and the bottom of the bending part 22 is fixedly connected with the vertical part 23, and the end of the vertical part 23 away from the bending part 22 is fixedly connected with the abutting part 24, and the bottom end surface of the abutting part 24 is provided with an anti-slip pattern 25 The anti-slip pattern 25 is provided with horizontal and vertical patterns, and the horizontal and vertical patterns are cross-distributed at 90 degrees. The abutment portion 24 is opened at one end away from the vertical portion 23 in a triangular arrangement, and the hypotenuse of the triangle abuts the polished surface. The triangular arrangement enables the abutment portion 24 to shovel up dust, and there is no dead angle between the abutment portion 24 and the polished surface, which facilitates the air pump 4 to suck dust. The side wall of the vertical portion 23 is fixedly connected to the air pump 4, and the air outlet of the air pump 4 is fixedly connected to the suction pipe 3. The outer wall of the vertical portion 23 is fixedly connected to a mounting ring 27, and the bottom end face of the mounting ring 27 is fixedly connected to a brush 28. The number of brushes 28 is set in several groups, and several groups of brushes 28 are arranged in an annular manner at equal intervals on the bottom end face of the mounting ring 27.

[0024] The sanding machine body 1 is brought into contact with the polishing surface. During the downward pressing process, the abutting portion 24 will first contact the polishing surface. The sanding machine body 1 is continuously pressed downward. The abutting portion 24 and the vertical portion 23 push the bending portion 22 to bend. The annular airbag 26 elastically pushes the abutting portion 24 to tightly abut against the polishing surface. Then, the bottom plate of the press sanding machine body 1 abuts against the polishing surface. The sanding machine body 1 is started to polish the polishing surface. The dust generated by the polishing is sucked out of the sanding machine body 1 by the suction pipe 3 and the air pump 4. By isolating the polishing range of the sanding machine body 1, the dust generated by the polishing is prevented from escaping into the air, thereby improving the cleanliness of the environment. In addition, since the ground of the abutting portion 24 is provided with anti-skid patterns 25, the anti-skid patterns 25 increase the friction between the dust collection component 2 and the polishing surface, thereby limiting the sanding machine body 1, reducing the torque generated on the operator's hand when the sanding machine body 1 rotates and polishes, thereby improving the comfort of the sanding machine body 1 operation.

[0025] In addition, the outer wall of the vertical portion 23 is fixedly connected to a mounting ring 27, and the bottom end face of the mounting ring 27 is fixedly connected to a brush 28. The number of brushes 28 is arranged in several groups, and several groups of brushes 28 are arranged in a ring shape at equal intervals on the bottom end face of the mounting ring 27. The brush 28 is always in contact with the polishing surface. When some dust leaks out from the gap between the abutting portion 24 and the polishing surface due to the unevenness of the polishing surface, the brush 28 can effectively prevent this part of the dust from continuing to spread into the environment, thereby improving the dust control effect.

[0026] In the utility model, when in use, the sanding machine body 1 is brought into contact with the polishing surface. During the pressing process, the abutting portion 24 will first contact the polishing surface. The sanding machine body 1 is continuously pressed down. The abutting portion 24 and the vertical portion 23 push the bending portion 22 to bend. The annular airbag 26 elastically pushes the abutting portion 24 to tightly abut against the polishing surface. Then, the bottom plate of the sanding machine body 1 is pressed against the polishing surface. The sanding machine body 1 is started to polish the polishing surface. The dust generated by the polishing is sucked out of the sanding machine body 1 by the suction pipe 3 and the air pump 4. The grinding range of the sanding machine body 1 is isolated, and the ground of the abutment part 24 is provided with anti-skid grooves 25. The anti-skid grooves 25 increase the friction between the dust collection component 2 and the grinding surface, thereby limiting the sanding machine body 1 and reducing the torque generated on the operator's hand when the sanding machine body 1 rotates for grinding. Furthermore, the brush 28 is always in contact with the grinding surface. When part of the dust leaks out from the gap between the abutment part 24 and the grinding surface due to the unevenness of the grinding surface, the brush 28 can well prevent this part of the dust from continuing to spread into the environment.

[0027] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
