Description

Technical Field

[0001] The invention relates to the technical field of polishing equipment, in particular to a steel wire polishing device for indoor decoration wood boards. Background Art

[0002] When the wire brush head runs or rubs on the surface of the wooden board at high speed, the wax oil can reduce the scratches and damage to the wooden board surface caused by excessive friction. In addition, there are usually some tiny pores and pits on the surface of the wooden board. The wax oil can fill these tiny defects to make the surface of the wooden board smoother. The wax oil can form a protective film on the surface of the wooden board, which can isolate the wooden board from some harmful substances in the external environment. The protective film can also resist a certain degree of physical wear and tear, thereby extending the service life of the wooden board.

[0003] The existing wire polishing device for indoor decoration wooden boards first applies wax oil on the wooden boards before polishing, and then grinds them. Since the wax oil is often a paste-like solid, it is not easy to apply the wax oil evenly on the wooden boards, thereby affecting the polishing effect of the wooden boards. Therefore, it does not meet the existing needs. In this regard, we propose a wire polishing device for indoor decoration wooden boards. Summary of the invention

[0015] The present invention has the following beneficial effects:

[0016] 1. The wire polishing device for indoor decoration wood boards, the brush head installed on the top of the rotating sleeve contacts the wax oil in the discharge sleeve. When the brush head installed at the bottom of the rotating sleeve polishes the wood board, the top brush head rotates synchronously and automatically brushes oil. At this time, the staff holds the hand grinder housing and presses the pressure rod at the same time. The pressure rod drives the No. 1 rack to move upward and drives the driving gear to rotate. The No. 1 torsion spring is twisted and stored, and the ratchet and the pawl are not engaged at this time. When the wax oil on the brush head installed at the bottom of the rotating sleeve is consumed, the staff lifts the hand grinder housing and the pressure rod The drive gear rotates in the opposite direction under the action of the No. 1 torsion spring, and the ratchet is engaged with the pawl at this time, and the connecting sleeve rotates ° under the drive of the driving gear, so that the brush head that has finished brushing the wax oil rotates to the bottom, and the brush head that has consumed the wax oil rotates to the top to brush oil again. Compared with directly applying wax oil to the wooden board, automatically applying wax oil to the brush head not only reduces the operation of manually applying wax oil and saves manpower, but also when the brush head grinds and polishes the wooden board, the wax oil will be evenly applied to the wooden board to prevent the wax oil from agglomerating into lumps, thereby increasing the practicality of the device.

[0017] 2. The wire polishing device for indoor decoration wooden boards, when the rotating sleeve rotates, the rotating sleeve drives the transmission gear to rotate through the connecting rod, and further drives the driven gear and the rotating seat to rotate. At this time, one end of the interference rod interferes with the inclined surface of the wedge block, so the interference rod moves in the direction away from the driven gear. At this time, the No. 1 compression spring is compressed and stored. When the rotating sleeve rotates after degrees, one end of the interference rod is no longer in contact with the wedge block. At this time, the wax oil box moves toward the driven gear under the action of the No. 1 compression spring, and at the same time, the wax oil is applied along the diameter direction of the brush head through the discharge sleeve. Compared with directly applying the wax oil to the brush head, the discharge sleeve moves while applying the wax oil, so that the wax oil is more evenly distributed on the brush head, which is beneficial to the wax oil being more evenly distributed on the wooden board during grinding and polishing, thereby improving the polishing effect of the wooden board and further increasing the practicality of the device.

[0018] 3. In the wire polishing device for indoor decoration wooden boards, when the rotating sleeve is flipped, the wax oil box moves in the direction away from the driven gear, the rotating plate does not rotate, and one end of the rotating plate conflicts with the wedge bar. The wedge bar drives the No. 2 rack to move away from the moving gear, so the No. 2 rack is not meshed with the moving gear. After the rotating sleeve is flipped, the rotating plate and the wedge bar are no longer in conflict. At this time, the No. 2 rack is meshed with the moving gear again under the action of the No. 2 compression spring, and the rotating sleeve moves in the opposite direction under the action of the No. 1 compression spring. At this time, the moving gear moves and rotates at the same time. Since the screw is threadedly connected to the moving gear, the screw continuously moves downward while the moving gear rotates, and then the wax oil is squeezed out through the pressure plate. Since the displacement of the rotating sleeve moving in the opposite direction each time under the action of the No. 1 compression spring is fixed, the downward displacement of the screw and the pressure plate is also fixed, thereby ensuring that the wax oil squeezed out of the pressure plate each time is also a fixed amount, further increasing the practicality of the device.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Embodiment 1: This embodiment is intended to promote the solution of the existing wire polishing device for indoor decoration wood boards. Before polishing, wax oil is first applied to the wood board, and then polished. Since the wax oil is often a paste solid, it is not easy to apply the wax oil evenly on the wood board, thereby affecting the polishing effect of the wood board. Please refer to Figure 1-9 A wire polishing device for indoor decoration wood boards includes a hand grinder housing 101, a brush head 102 is arranged on the hand grinder housing 101, a motor 103 for driving the brush head 102 to rotate is arranged inside the hand grinder housing 101, a rotating sleeve 202 is rotatably installed on the hand grinder housing 101, a pair of brush heads 102 are arranged, and the pair of brush heads 102 are rotatably installed at both ends of the rotating sleeve 202, a slide plate 216 is arranged on the hand grinder housing 101, a wax oil box 214 for containing wax oil is arranged on the slide plate 216, the wax oil box 214 is located directly above the brush head 102, and a discharge sleeve 215 for releasing wax oil is arranged at the bottom of the wax oil box 214, and the brush head 102 at the top of the rotating sleeve 202 contacts the wax oil in the discharge sleeve 215.

[0031] For details, please refer to Figure 2 A connecting sleeve 203 is rotatably installed at one end of the hand grinder housing 101, and a rotating sleeve 202 is fixedly connected to the connecting sleeve 203. The motor 103 is installed in the connecting sleeve 203. A rotating shaft 205 is rotatably installed in the rotating sleeve 202. Turntables 204 are installed at both ends of the rotating shaft 205. The brush head 102 is installed on the turntable 204. A driving bevel gear 207 is installed on the output shaft of the motor 103, and a driven bevel gear 206 is installed on the rotating shaft 205. The driven bevel gear 206 is meshed with the driving bevel gear 207.

[0032] In addition, a fixed rod 209 is fixedly installed in the hand grinder housing 101, and a rotating rod 210 is fixedly installed at one end of the connecting sleeve 203. The rotating rod 210 is rotatably connected to the fixed rod 209. A driving gear 213 is rotatably installed on the fixed rod 209, and a synchronous sleeve 211 is installed on the side of the driving gear 213. A No. 1 torsion spring 212 is arranged in the synchronous sleeve 211, and the other end of the No. 1 torsion spring 212 is fixedly connected to the fixed rod 209. When the synchronous sleeve 211 rotates, the No. 1 torsion spring 212 twists and accumulates force. A pressure rod 201 is slidably installed in the hand grinder housing 101, and a No. 1 rack 219 for meshing with the driving gear 213 is arranged on the top of the pressure rod 201. When the pressure rod 201 moves upward, the driving gear 213 drives the synchronous sleeve 211 to rotate.

[0033] Also, please refer to Figure 3 , Figure 4 A ratchet 220 is provided on the side of the driving gear 213, and a pawl 221 is provided on the rotating rod 210. The rotating rod 210 and the pawl 221 are movably engaged. Specifically, when the pressure rod 201 drives the No. 1 rack 219 to move upward, and at the same time drives the driving gear 213 to rotate, the ratchet 220 and the pawl 221 are not engaged at this time, and the staff lifts the hand grinder housing 101, the pressure rod 201 and the wooden board no longer conflict with each other, and the driving gear 213 rotates in the opposite direction under the action of the No. 1 torsion spring 212. At this time, the ratchet 220 and the pawl 221 are engaged, and the pawl 221 can rotate unidirectionally through the spring cooperation. The ratchet and pawl are common mechanical cooperation means, which are well known to those skilled in the art and will not be described in detail here.

[0034] In this embodiment: the brush head 102 installed on the top of the rotating sleeve 202 contacts the wax oil in the discharge sleeve 215. When the brush head 102 installed at the bottom of the rotating sleeve 202 grinds the wooden board, the top brush head 102 rotates synchronously and automatically brushes oil. At this time, the staff holds the hand grinder housing 101 and presses the pressure rod 201 at the same time. The pressure rod 201 drives the No. 1 rack 219 to move upward, and at the same time drives the driving gear 213 to rotate. The No. 1 torsion spring 212 is twisted and stored. At this time, the ratchet 220 and the pawl 221 are not engaged, so the driving gear 213 will not drive the rotating sleeve 202 to rotate. When the wax oil on the brush head 102 installed at the bottom of the rotating sleeve 202 is consumed, the staff lifts the hand grinder housing 101, the pressure rod 201 no longer conflicts with the wooden board, and the driving gear 213 rotates in the opposite direction under the action of the No. 1 torsion spring 212, at which time the ratchet 220 is engaged with the pawl 221, and the connecting sleeve 203 rotates 180° driven by the driving gear 213, so that the brush head 102 that has finished brushing the wax oil rotates to the bottom, and the brush head 102 that has consumed the wax oil rotates to the top to brush the oil again. Since the wax oil is a paste-like solid, if the wax oil is directly applied to the wooden board, the wax oil will clump, resulting in uneven distribution of the wax oil on the wooden board. The device automatically applies the wax oil to the brush head 102, which not only reduces the operation of manually applying the wax oil and saves manpower, but also when the brush head 102 polishes the wooden board, the contact surface of the brush head 102 and the wooden board always has wax oil, so the brush head 102 will evenly apply the wax oil on the wooden board to prevent the wax oil from agglomerating into lumps, thereby increasing the practicality of the device.

[0035] Embodiment 2: This embodiment is intended to promote the solution of the problem that the wax oil is directly applied to the brush head 102 through the discharge sleeve 215, which will cause the wax oil to gather into lumps on the brush head 102 and the wax oil on the brush head 102 cannot be evenly distributed during grinding. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-9 A slide groove 217 is provided on the slide plate 216, and the wax oil box 214 is slidably installed in the slide groove 217. A through groove 218 is opened in the slide groove 217, and the discharge sleeve 215 is in sliding contact with the inner wall of the through groove 218. When applying wax oil, the discharge sleeve 215 moves along the diameter direction of the brush head 102 to evenly apply the wax oil on the brush head 102.

[0036] Also, please refer to Figure 2 A positioning rod 301 is installed on one side of the wax oil box 214, and a No. 1 compression spring 309 is arranged on the positioning rod 301. A vertical plate 308 is installed on the hand grinder housing 101. The positioning rod 301 is inserted into the vertical plate 308, and one end of the No. 1 compression spring 309 is in contact with the vertical plate 308. A wedge block 306 is installed on the rotating seat 305, and a resistance rod 307 is installed on the other end of the wax oil box 214. When one end of the resistance rod 307 is in contact with the inclined surface of the wedge block 306, the resistance rod 307 moves away from the driven gear 304.

[0037] It should be noted that after the pressure on the pressure rod 201 stops, the rotating sleeve 202 rotates driven by the No. 1 torsion spring 212, and further rotates the rotating seat 305 through the transmission of the transmission gear 303 and the driven gear 304. At this time, the inclined surface of the wedge block 306 on the rotating seat 305 conflicts with one end of the interference rod 307, thereby driving the interference rod 307 to move away from the driven gear 304, and at this time, the rotating plate 408 does not deflect, and one end of the rotating plate 408 conflicts with the wedge bar 404, so that the No. 2 rack 402 moves away from the moving gear 403. , therefore, the No. 2 rack 402 is not meshed with the moving gear 403. When the rotating seat 305 rotates 180° along with the rotating sleeve 202, one end of the abutment rod 307 separates from the wedge block 306, and the abutment rod 307 and the wax oil box 214 are reset under the action of the No. 1 compression spring 309. During the resetting of the wax oil box 214, the rotating plate 408 rotates, and the No. 2 rack 402 is re-engaged with the moving gear 403 under the action of the No. 2 compression spring 407. Therefore, the moving gear 403 rotates while the wax oil box 214 is reset, further causing the pressure plate 411 to move downward to squeeze out the wax oil.

[0038] In this embodiment, when the rotating sleeve 202 rotates, the rotating sleeve 202 drives the transmission gear 303 to rotate through the connecting rod 302, and further drives the driven gear 304 and the rotating seat 305 to rotate. At this time, one end of the contact rod 307 contacts the inclined surface of the wedge block 306, so the contact rod 307 moves away from the driven gear 304. At this time, the first compression spring 309 is compressed and stored. When the rotating sleeve 202 rotates 180°, one end of the contact rod 307 is no longer in contact with the wedge block 306. At this time, the wax oil box 2 14 moves toward the driven gear 304 under the action of the No. 1 compression spring 309, and at the same time, the wax oil is applied along the diameter direction of the brush head 102 through the discharge sleeve 215. Compared with directly applying the wax oil on the brush head 102, the discharge sleeve 215 moves while applying the wax oil, so that the wax oil is more evenly distributed on the brush head 102, which is beneficial for the wax oil to be more evenly distributed on the wooden board during grinding and polishing, thereby improving the polishing effect of the wooden board and further increasing the practicality of the device.

[0039] Embodiment 3: This embodiment aims to solve the problem that the amount of wax applied each time is not fixed by rotating the brush head 102. This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-9A pressure plate 411 for squeezing wax oil is movably provided in the wax oil box 214, a screw 401 is installed on the pressure plate 411, a moving sleeve 406 is slidably installed inside the hand grinder housing 101, a moving gear 403 is rotatably installed on the bottom end of the moving sleeve 406, the moving gear 403 is threadedly connected with the screw 401, a flat plate 409 is provided on the side of the vertical plate 308, a No. 2 rack 402 is provided on the flat plate 409, the No. 2 rack 402 is meshed with the moving gear 403, and when the moving gear 403 rotates, the pressure plate 411 moves downward.

[0040] Also, please refer to Figure 6 A plurality of No. 2 compression springs 407 are arranged on the flat plate 409, the other end of the No. 2 compression spring 407 is fixedly connected to the No. 2 rack 402, a wedge-shaped bar 404 is arranged on the No. 2 rack 402, an L-shaped rod 405 is installed on the abutment rod 307, a rotating plate 408 is movably arranged on the other end of the L-shaped rod 405, one end of the rotating plate 408 is in contact with the wedge-shaped bar 404, a No. 2 torsion spring 410 is arranged on the rotating plate 408, and the other end of the No. 2 torsion spring 410 is fixedly connected to the L-shaped rod 405.

[0041] In this embodiment, when the rotating sleeve 202 is turned over, the wax oil box 214 moves away from the driven gear 304, the rotating plate 408 does not rotate, and one end of the rotating plate 408 conflicts with the wedge bar 404, and the wedge bar 404 drives the second rack 402 to move away from the moving gear 403, so the second rack 402 and the moving gear 403 do not mesh. After the rotating sleeve 202 is turned over, the rotating plate 408 and the wedge bar 404 no longer conflict, and at this time, the second rack 402 is meshed with the moving gear 403 again under the action of the second compression spring 407, and the rotating sleeve 202 is in a The movable gear 403 moves in the reverse direction under the action of the compression spring 309. At this time, the movable gear 403 moves and rotates at the same time. Since the screw 401 is threadedly connected with the movable gear 403, the screw 401 moves downward continuously while the movable gear 403 rotates, and then the wax oil is squeezed out through the pressure plate 411. Since the displacement of the rotating sleeve 202 moving in the reverse direction each time under the action of the compression spring 309 is fixed, the downward displacement of the screw 401 and the pressure plate 411 is also fixed, thereby ensuring that the wax oil squeezed out by the pressure plate 411 each time is also a fixed amount, further increasing the practicality of the device.

[0042] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention.
