Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.
[0027] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc. indicating the orientation or position relationship are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the utility model.
[0028] Please refer to Figures 1-6 As shown, the present utility model is a curved surface polishing device for wooden tableware, including a housing 1. A feeding assembly 2 and a polishing assembly 3 are arranged inside the housing 1. An elastic assembly 4 is arranged on the outer surface of the polishing assembly 3. A transmission assembly 5 is arranged on the outer surface of the housing 1. The feeding assembly 2 is used to drive the wooden tableware to move. The polishing assembly 3 is used to polish the wooden tableware on the feeding assembly 2. The elastic assembly 4 is used to enable a part of the structure of the feeding assembly 2 to move up and down within a small range to apply a downward pressure to different tableware.
[0029] Put the wooden tableware into the feeding component 2, and the feeding component 2 drives the wooden tableware to move into the polishing component 3 in the housing 1 for polishing. During the moving process, the feeding component 2 can move up and down within a small range under the action of the elastic component 4, so that the feeding component 2 can maintain a certain clamping force on the wooden tableware while avoiding breaking the wooden tableware. The wood chips generated when the polishing component 3 polishes the wooden tableware fall into the housing 1. Through the setting of the transmission component 5, the driving source of the polishing component 3 drives the polishing component 3 to work through the transmission component 5, and the driving source of the polishing component 3 can be arranged on the outer surface of the housing 1 to prevent wood chips from entering the inside of the driving source of the polishing component 3.
[0030] In the utility model, through the connection of the feeding component 2 and the elastic component 4, the feeding component 2 is divided into two parts. The upper half of the feeding component 2 is connected to the elastic component 4, so that the upper half of the feeding component 2 can move up and down within a small range through the elastic component 4. At this time, the position of the upper half of the feeding component 2 can be adjusted according to the curved surface shape of the wooden tableware, avoiding breakage of the wooden tableware during the feeding and polishing process.
[0031] In one embodiment, for the above-mentioned feeding component 2, the feeding component 2 includes a first rotating shaft 201, the first rotating shaft 201 is rotatably connected inside the housing 1, a first feeding roller 202 is fixedly connected to the outer surface of the first rotating shaft 201, a second rotating shaft 203 is slidably connected inside the housing 1, a second feeding roller 204 is fixedly connected to the outer surface of the second rotating shaft 203, and the second rotating shaft 203 can slide and rotate inside the housing 1. There are multiple groups of the first rotating shaft 201, the first feeding roller 202, the second rotating shaft 203 and the second feeding roller 204.
[0032] The first rotating shaft 201 can rotate actively, and the power source of the first rotating shaft 201 is installed in the box on the side of the housing 1. When the wooden tableware is placed between the first feeding roller 202 and the second feeding roller 204, the first rotating shaft 201 drives the first feeding roller 202 to rotate to push the wooden tableware to move, and the second feeding roller 204 rotates passively while applying a certain downward pressure on the wooden tableware.
[0033] In one embodiment, for the above-mentioned polishing assembly 3, the polishing assembly 3 includes a first polishing wheel 301, a first gear 302 is fixedly connected to the outer surface of the first polishing wheel 301, a second gear 303 meshes with the outer surface of the first gear 302, and a second polishing wheel 304 is fixedly connected to the outer surface of the second gear 303. There are two sets of the first polishing wheel 301, the first gear 302, the second gear 303 and the second polishing wheel 304. The axes of the two sets of the first polishing wheels 301 and the second polishing wheels 304 are perpendicular to each other. The two sets of the first polishing wheels 301 and the second polishing wheels 304 are rotatably connected to the inside of the housing 1, and a motor 305 is drivingly connected to the outer surface of the first gear 302.
[0034] Start the motor 305. The motor 305 transmits power to the first gear 302. The first gear 302 meshes with the second gear 303, so that the first polishing wheel 301 and the second polishing wheel 304 on the first gear 302 and the second gear 303 rotate simultaneously. The polishing material on the first polishing wheel 301 and the second polishing wheel 304 is sandpaper. The softness of the sandpaper enables it to adapt to the curved surface radian of the wooden tableware. The first polishing wheel 301 and the second polishing wheel 304 are divided into two groups, namely horizontal and vertical. The vertical first polishing wheel 301 and the second polishing wheel 304 are used to polish the sides of the wooden tableware, and the horizontal first polishing wheel 301 and the second polishing wheel 304 are used to polish the upper and lower surfaces of the wooden tableware.
[0035] The first set of the first feeding rollers 202 and the second feeding rollers 204 squeeze and push the wooden tableware to move between the vertical first polishing wheel 301 and the second polishing wheel 304. At this time, the vertical first polishing wheel 301 and the second polishing wheel 304 polish the sides of the wooden tableware. During the movement, the front part of the wooden tableware gradually enters the first feeding rollers 202 and the second feeding rollers 204 located in the middle position. At this time, the first feeding rollers 202 and the second feeding rollers 204 located in the middle position continue to drive the wooden tableware to move, and make the wooden tableware enter between the horizontal first polishing wheel 301 and the second polishing wheel 304. At this time, the horizontal first polishing wheel 301 and the second polishing wheel 304 polish the upper and lower surfaces of the wooden tableware. The wooden tableware gradually moves between the third set of the first feeding rollers 202 and the second feeding rollers 204 and exits under the pushing action of the third set of the first feeding rollers 202 and the second feeding rollers 204.
[0036] In one embodiment, for the above-mentioned elastic component 4, the elastic component 4 includes a sliding seat 401 which is slidably connected inside the housing 1. The sliding seat 401 is rotatably connected to the second rotating shaft 203. A sliding plate 402 is fixedly connected to the outer surface of the sliding seat 401. The sliding plate 402 is slidably connected inside the housing 1. A spring 403 is fixedly connected to the bottom of the sliding plate 402, and the lower end of the spring 403 is fixedly connected inside the housing 1.
[0037] When the wooden tableware enters between the first feeding roller 202 and the second feeding roller 204, the wooden tableware can lift the second feeding roller 204. The second rotating shaft 203 on the second feeding roller 204 drives the sliding seat 401 to move. The sliding seat 401 drives the sliding plate 402 to slide and stretch the spring 403. As the wooden tableware moves, the second feeding roller 204 can move up and down to adapt to the curved surface radian of the wooden tableware, avoiding the situation of breakage caused by excessive extrusion.
[0038] In one embodiment, for the above-mentioned transmission component 5, the transmission component 5 includes a first pulley 501 which is fixedly connected to the output shaft of the motor 305. A belt 502 is installed on the outer surface of the first pulley 501. The first pulley 501 is drivingly connected to a second pulley 503 through the belt 502. A transmission shaft 504 is fixedly connected to the outer surface of the second pulley 503. A first bevel gear 505 is fixedly connected to the end of the transmission shaft 504. A second bevel gear 506 is meshed with the outer surface of the first bevel gear 505, and the second bevel gear 506 is fixedly connected to the first gear 302.
[0039] The output shaft of the motor 305 drives the first pulley 501 to rotate. The first pulley 501 drives the second pulley 503 to rotate synchronously through the belt 502. The second pulley 503 drives the first bevel gear 505 to rotate through the transmission shaft 504. The first bevel gear 505 meshes with the second bevel gear 506 and drives it to rotate. At this time, the two groups of first gears 302 in the horizontal and vertical directions are simultaneously driven. The two groups of first gears 302 are respectively meshed with the two groups of second gears 303, so that the two groups of first polishing wheels 301 and the second polishing wheels 304 can rotate simultaneously. Moreover, the motor 305 is located outside the housing 1, which can prevent the wood chips generated during the polishing process from entering the motor 305.
[0040] In one embodiment, for the above-mentioned housing 1, a baffle 6 is rotatably connected to the outer surface of the housing 1, and a handle 7 is fixedly connected to the outer surface of the baffle 6.
[0041] In one embodiment, for the above-mentioned baffle 6, a first fixing seat 8 is fixedly connected to the outer surface of the baffle 6, a second fixing seat 9 is fixedly connected to the outer surface of the housing 1, and a bolt 10 is slidably connected between the first fixing seat 8 and the second fixing seat 9.
[0042] Pull the bolt 10 to separate it from the first fixing seat 8 on the baffle 6, release the limit fixation of the baffle 6, pull the handle 7 to drive the baffle 6 to rotate and open it. At this time, the wood chips in the housing 1 can be cleaned.
[0043] Through the above technical solutions: 1. Through the connection between the feeding component 2 and the elastic component 4, the feeding component 2 is divided into two parts. The upper half of the feeding component 2 is connected to the elastic component 4, so that the upper half of the feeding component 2 can move up and down within a small range through the elastic component 4. At this time, the position of the upper half of the feeding component 2 can be adjusted according to the curved surface shape of the wooden tableware, avoiding breakage of the wooden tableware during the feeding and polishing process; 2. Through the connection between the first gear 302 and the second bevel gear 506, the second bevel gear 506 meshes with the first bevel gear 505, and the first bevel gear 505 is installed on the transmission shaft 504. When the motor 305 is started, it can drive the horizontal first gear 302 and the first pulley 501 to rotate. The first pulley 501 drives the second pulley 503 and the transmission shaft 504 to rotate through the belt 502. The transmission shaft 504 transmits the power to the longitudinal first gear 302, so that the two groups of horizontal and longitudinal first gears 302 rotate simultaneously. At this time, the longitudinal first gear 302 does not require an additional drive source, and only one motor 305 needs to be installed outside the housing 1, avoiding the influence of wood chips when the motor 305 is installed inside the housing 1 to drive the longitudinal first gear 302.
