Description

Technical Field

[0001] The utility model relates to the technical field of dry sandpaper, in particular to an open anti-static dry sandpaper. Background Art

[0002] The open dry sandpaper is a special tool for grinding and polishing, and is widely used in the surface treatment of various materials such as wood, metal, and plastic.

[0003] The open dry sandpaper generally consists of a sandpaper base layer and an abrasive layer. Among them, the sandpaper base layer generally uses a high-strength and high-toughness backing paper as the base material, and the abrasive layer generally uses an alumina high-hardness material layer.

[0004] At present, for the existing open dry sandpaper, when in use, due to continuous friction, static electricity is easily generated. The static electricity will cause environmental dust and debris to adhere to the surface of the abrasive layer of the dry sandpaper body, resulting in a decrease in the cleanliness of the abrasive layer of the dry sandpaper body and a decrease in the grinding sharpness of the abrasive layer.

[0005] In addition, for the existing open dry sandpaper, when grinding the grinding surface, the side wall surface and the corners of its sandpaper base layer are easily curled under the abrasive layer. At this time, the operator needs to stop the grinding work and turn the sandpaper base layer curled under the abrasive layer up again, and then continue the grinding operation. This will affect the normal grinding work and efficiency of the open dry sandpaper. Summary of the Utility Model

[0006] The purpose of the utility model is to solve the above-mentioned disadvantages in the prior art, and to propose an open anti-static dry sandpaper.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] Design an open anti-static dry sandpaper, including a dry sandpaper body. The dry sandpaper body consists of a sandpaper base layer and an abrasive layer, and the abrasive layer is arranged on the lower end surface of the sandpaper base layer;

[0009] A liquid storage box is arranged on the sandpaper base layer. An extrusion support column is arranged on the liquid storage box, and a pressing frame is arranged on the extrusion support column. A liquid storage cavity is arranged in the liquid storage box, and an anti-static liquid is arranged in the liquid storage cavity. Liquid outlet holes are arranged on the dry sandpaper body, and a dust-proof net and a liquid-absorbing cotton are arranged in the liquid outlet holes;

[0010] A warping panel is arranged on the dry sandpaper body, and a smooth layer is arranged on the warping panel.

[0011] Further, the liquid storage box and the pressing frame are in a group, and there are two groups symmetrically arranged in total. Both the liquid storage box and the pressing frame are made of plastic steel material.

[0012] Further, the extrusion supporting column and the liquid outlet hole are in a group, and there are seven groups arranged longitudinally in total. The extrusion supporting column is arranged between the liquid storage box and the pressing frame.

[0013] Further, the liquid outlet hole communicates with the liquid storage cavity and vertically penetrates through the sandpaper base layer and the abrasive layer. The inner hole structure of the liquid outlet hole facing downward is a constricted structure.

[0014] Further, the dust-proof net is arranged at the lower end of the liquid-absorbing cotton, and the liquid-absorbing cotton is filled in the liquid outlet hole.

[0015] Further, the number of the warped panels is four. The cross-section of the warped panel is an arc-shaped structure and is respectively arranged on the four side surfaces of the dry sandpaper body. The warped panel is made of nylon material.

[0016] Further, the smooth layer is arranged on the lower end surface of the warped panel, and the smooth layer is a PTFE polytetrafluoroethylene coating.

[0017] An open-type anti-static dry sandpaper proposed by the present utility model has the following beneficial effects:

[0018] 1.

[0019] 2. By setting a warped panel structure on the four side walls of the dry sandpaper body and a smooth layer structure on the warped panel, when using the dry sandpaper body for friction grinding, the situation that the side wall surface and the corner of the sandpaper base layer curl under the abrasive layer is effectively avoided, and thus the normal grinding work and efficiency of the open-type dry sandpaper are effectively improved.

Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0027] Refer to Figures 1-5 , an open - type antistatic dry sandpaper, including a dry sandpaper body 1, the dry sandpaper body 1 is composed of a sandpaper base layer 11 and an abrasive layer 12, and the abrasive layer 12 is arranged on the lower end surface of the sandpaper base layer 11;

[0028] A liquid storage box 3 is arranged on the sandpaper base layer 11, an extrusion support column 4 is arranged on the liquid storage box 3, a pressing frame 41 is arranged on the extrusion support column 4, a liquid storage cavity 31 is opened in the liquid storage box 3, an antistatic liquid 32 is arranged in the liquid storage cavity 31, a liquid outlet hole 5 is opened on the dry sandpaper body 1, and a dustproof net 6 and a liquid absorption cotton 7 are arranged in the liquid outlet hole 5;

[0029] A warped panel 2 is arranged on the dry sandpaper body 1, a smooth layer 21 is arranged on the warped panel 2. The dry sandpaper body 1 is an open - type dry sandpaper, which is prior art. Among them, the sandpaper base layer 11 and the abrasive layer 12 are its related prior art structures. Some prior art structures are not drawn and marked, so there is no need to elaborate.

[0030] The antistatic liquid 32 is prior art and has an antistatic effect. When the antistatic liquid 32 is extruded through the liquid outlet hole 5, the antistatic effect on the friction part is achieved.

[0031] The liquid storage box 3 and the pressing frame 41 are a group, and there are two groups symmetrically arranged in total. The liquid storage box 3 and the pressing frame 41 are both made of plastic steel material, with a certain elastic softness. When not pressed, they can perform elastic deformation and reset themselves.

[0032] The liquid storage box 3 is preset with a liquid replenishing hole, and a sealing plug made of elastic polyurethane is inserted into the liquid replenishing hole by extrusion and sealing (not shown in the figure). Pull out the sealing plug, and the anti-static liquid 32 can be replenished into the liquid storage cavity 31.

[0033] The extrusion supporting column 4 and the liquid outlet hole 5 are a group, and there are a total of seven groups arranged longitudinally. The extrusion supporting column 4 is arranged between the liquid storage box 3 and the pressing frame 41. When the pressing frame 41 is pressed downward, the pressing frame 41 with a certain elasticity and softness will deform, and the anti-static liquid 32 can be squeezed and absorbed into the liquid absorbing cotton 7.

[0034] The extrusion supporting column 4 is made of hard silicone material, does not deform, and is resistant to extrusion.

[0035] The liquid outlet hole 5 communicates with the liquid storage cavity 31 and vertically penetrates through the sandpaper base layer 11 and the abrasive layer 12. The inner hole structure of the liquid outlet hole 5 facing downward is a retracted structure. Without squeezing out the anti-static liquid 32, combined with the dust-proof net 6, dust particles can be prevented from entering.

[0036] The dust-proof net 6 is arranged at the lower end of the liquid absorbing cotton 7. The dust-proof net 6 has strong toughness and wear resistance, can prevent dust particles from entering the liquid outlet hole 5 during grinding, and can also allow the anti-static liquid 32 to pass through.

[0037] The liquid absorbing cotton 7 is filled in the liquid outlet hole 5. The liquid absorbing cotton 7 is made of soft polypropylene material, can quickly absorb the anti-static liquid 32, and after being saturated with absorption, it is extruded downward through the liquid outlet hole 5 under the vertical extrusion force.

[0038] The number of the warped panels 2 is four. The cross-section of the warped panel 2 is an arc-shaped structure and is respectively arranged on the four side surfaces of the dry sandpaper body 1. The warped panel 2 is made of nylon material, and the nylon material has strong toughness and does not deform, avoiding the situation that the side wall surface and the corner of the sandpaper base layer 11 curl under the abrasive layer 12.

[0039] The smooth layer 21 is arranged on the lower end surface of the warped panel 2. The smooth layer 21 is a PTFE polytetrafluoroethylene coating. The PTFE polytetrafluoroethylene coating has excellent smoothness, a flat and smooth surface, and low friction, further improving the smoothness during the use of the dry sandpaper body 1 for grinding.

[0040] Working mode: When used through the dry abrasive paper body 1, continuous friction generates static electricity. At this time, the pressing frame 41 can be pressed downward. By pressing the supporting column 4, the liquid storage box 3 is extruded. The liquid storage cavity 31 of the liquid storage box 3 itself will deform, and the anti-static liquid 32 inside the liquid storage cavity 31 will be quickly absorbed by the liquid absorption cotton 7. After the liquid absorption cotton 7 is saturated with absorption, the anti-static liquid 32 will be evenly coated on the friction part of the abrasive layer 12 through the liquid outlet hole 5, achieving the anti-static effect on the friction part. At this time, the grinding operation is carried out through the dry abrasive paper body 1, effectively avoiding the attachment of environmental dust and debris caused by static electricity on the surface of the abrasive layer 12 of the dry abrasive paper body 1, and further avoiding the reduction of the cleanliness of the abrasive layer 12 of the dry abrasive paper body 1 and the reduction of the grinding sharpness of the abrasive layer.

[0041] In addition, when using the dry abrasive paper body 1 for friction grinding, the structure of the warped panel 2 with a smooth layer 21 provided on the four sides effectively avoids the situation that the side wall surface and the corners of the sandpaper base layer 11 curl under the abrasive layer 12, thereby effectively improving the normal grinding work and efficiency of the open dry abrasive paper.

[0042] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
