Description

Technical Field

[0001] The invention relates to the technical field of lacquerware polishing, in particular to a lacquerware polishing device integrating multiple processes. Background Art

[0002] The traditional lacquerware polishing process is a core step in the meticulous treatment of multiple layers of lacquer. Key steps include manual oiling, powdering, and sandpapering. The oiling process involves covering the lacquerware surface with vegetable oil (such as tung oil or castor oil), allowing the oil to penetrate and fill the microscopic pores in the paint layer, creating a foundation for the gloss. The powdering process involves applying polishing powder (natural powders such as deer antler powder or tile ash) to the surface to absorb excess oil. The sandpapering process involves dozens of hand-polishing cycles using sandpaper of varying grits (typically increasing in scale from 400 to 2000 grit) to achieve a mirror-like finish.

DETAILED DESCRIPTION

[0017] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present application belongs.

[0018] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0019] Example 1: Figures 1 to 15 As shown, a multi-step lacquerware polishing device comprises a base 1 and a support column 2 at its upper end for mounting the lacquerware in an inverted manner. The lower end of the support column 2 is pivotally connected to the base. Multiple circumferentially distributed polishing mechanisms are disposed around the support column 2. The base is equipped with a transmission mechanism 5 for controlling the operation of the polishing mechanisms. A side panel 12 is fixedly mounted on one side of the base, positioned outside the polishing mechanisms. The side panel 12 is taller than the support column. Two lifting mechanisms are mounted on the side panel 12, each equipped with a nozzle 33 for spraying oil and polishing powder, respectively, onto the surface of the lacquerware 6. The upper end of the support column 2 supports and secures the lacquerware 6. When the support column 2 rotates, the nozzles 33 spray oil onto the surface of the lacquerware 6, forming a process step for spraying oil onto the surface of the lacquerware 6. The nozzles 33 spray polishing powder onto the surface of the lacquerware 6, forming a process step for spreading a layer of polishing powder onto the surface of the lacquerware 6. The polishing mechanisms move across the surface of the lacquerware, forming the process step for polishing.

[0020] A first motor 21 is installed at the bottom of the base 1, a bearing seat is fixed on the base 1, and the lower end of the support column 2 passes through the bearing seat and is connected to the output end of the first motor 21, so that the first motor 21 can drive the support column 2 to rotate.

[0021] In this embodiment, a swing arm 22 extending toward the center and rotatable horizontally is hingedly connected to the upper end of the side panel 12. A vertical screw 23 is threadedly connected to the free end of the swing arm 22. The lower end of the vertical screw 23 is rotatably connected to a pressure plate 231 for pressing the paint container 6. A rotating handle is fixedly connected to the upper end of the vertical screw 23. The vertical screw 23 and the pressure plate 231 can be connected by embedding a bearing at the upper end of the pressure plate 231, and the lower end of the vertical screw 23 is inserted into and fixed to the bearing at the upper end of the pressure plate 231. After the lacquerware 6 is put on the outside of the support column 2 and the support column 2 supports the lacquerware 6 to the suspended support platform 11, the vertical screw 23 is loosened to allow the pressure plate 231 to press the lacquerware 6 supported by the support column 2, so that the support column 2 fixes the lacquerware 6 on the support column 2, and when the first motor 21 drives the support column 2 to rotate, the lacquerware 6 can be driven to rotate on the support platform 11. During the process, since the pressure plate 231 can rotate relative to the vertical screw 23, the pressure plate 231 pressing the lacquerware 6 will not affect the rotation of the lacquerware 6, but will rotate with it.

[0022] The lifting mechanism 3 can be a ball screw linear slide 31, which is arranged vertically. The nozzle 33 is fixed to the slide 32 of the ball screw linear slide 313. The slide 32 in the lifting mechanism 3 slides up and down, which drives the nozzle 33 to move up and down relative to the surface of the lacquerware 6. Furthermore, the lacquerware polishing device of the present invention can also be equipped with an oil tank and a powder tank. The nozzles 33 of the two lifting mechanisms 3 are connected to the oil tank and the powder tank respectively by hoses. The oil in the oil tank is pumped to the nozzle 33 for spraying, and the powder in the powder tank is pumped to the nozzle 33.

[0023] In this embodiment, the polishing mechanism includes a liftable upright 41 and a push plate 42 connected to the upper end of the upright 41 for contacting the surface of the lacquerware 6. Sandpaper 421 is fixedly provided on the push plate 42 facing the lacquerware 6. The sandpaper 421 can be fixed by Velcro to facilitate replacement of the sandpaper 421.

[0024] In this embodiment, the transmission mechanism 5 includes a lifting control device for controlling the elevation of the upright 41 and an elastic movement device for controlling the horizontal movement of the push plate 42. The lifting control device includes a transmission ring 51 rotatably mounted on a base, the rotational centerline of the transmission ring 51 coinciding with the axis of the support column 2. The transmission ring 51 is also provided with a plurality of upwardly protruding push portions 512 at intervals on its upper side, with slopes formed on either side of the push portions 512. The lower end of the upright 41 is provided with rollers 43 abutting against the upper side of the transmission ring 51, so that when the transmission ring 51 rotates, the rollers 43 and the push portions 512 cooperate to control the elevation of the upright 41. When the transmission ring 51 rotates until the push portions 512 are located at the position of the rollers 43, the rollers 43 follow the slopes of the push portions 512, driving the upright 41 and the push plate 42 upward and downward, thereby driving the sandpaper 421 to rise and fall relative to the lacquerware 6, thereby polishing the surface of the lacquerware 6.

[0025] In this embodiment, the elastic moving device includes a support platform 11 located above the base 1, and the two sides of the bottom of the support platform 11 are connected to the base 1 by a pair of fixed plates 13. A turntable 54 is rotatably arranged above the support platform 11, and the support column 2 passes through the middle of the support platform 11 and the turntable 54; the support platform 11 is provided with a sliding member 55 that corresponds one-to-one to each vertical rod 41 and can slide radially. The connection structure of the sliding member 55 can be a slider fixedly connected to the support platform 11, and the slider is adapted to connect the slide rail, and the slide rail is fixed to the bottom of the sliding member 55, thereby limiting the sliding member 55 to only slide linearly along the radial direction relative to the slider. The outward end of the slider 55 is provided with a guide hole 5501 for the vertical rod 41 to pass through and slide with. The guide hole 5501 can be a regular hexagonal hole, and the vertical rod 41 can be a hexagonal prism, so as to prevent the vertical rod 41 from rotating. The turntable 54 is provided with an arcuate groove 5401 corresponding to each slider 55. One end of the arcuate groove 5401 is close to the center of the turntable 54 and the other end is away from the center of the turntable 54. The inward end of the slider 55 is connected to a guide wheel 551 that fits in the arcuate groove 5401. When the turntable 54 rotates, the arcuate groove 5401 drives the guide wheel 551 to move relative to the support column 2. When the guide wheel 551 moves to the end of the arcuate groove 5401 close to the center of the turntable 54, it drives the slider 55 and the vertical rod 41 to move inwardly toward the support column 2. When the guide wheel 551 moves to the end of the arcuate groove 5401 away from the center of the turntable 54, it drives the slider 55 and the vertical rod 41 to move outward.

[0026] In this embodiment, a sleeve 541 is fixedly mounted at the bottom of the turntable 54. The sleeve 541 is rotatably connected to the support platform 11. A first gear 561 is fixed to the outside of the sleeve 541. A first rack 562 is positioned adjacent to the first gear 561, meshing with it and capable of horizontal reciprocating movement. A second spring 563 is connected between the first rack 562 and the fixed plate 13 on one side, enabling the turntable 54 to drive the guide wheel 551 toward the end of the arcuate slot 5401 near the center of the turntable 54. The turntable 54 exerts a torsional elastic force, which drives the guide wheel 551 toward the end of the arcuate slot 5401 near the center of the turntable 54. This allows the push plate 42 to elastically move relative to the support column 2, allowing it to follow the curved surface of the lacquerware 6 during its raising and lowering motion. The tension of the second spring 563 pushes the first rack 562 in one direction, driving the first gear 561 to rotate in one direction, thereby creating an elastic force that torsional resets the turntable 54.

[0027] When each push plate 42 moves upward, the push plate 42 moves against the lacquerware 6 to the bottle belly above it and expands outward, causing the guide wheel 551 to move outward and drive the turntable 54 to rotate in the opposite direction, causing the first gear 561 to rotate in the opposite direction. At this time, the first gear 561 rotates in the opposite direction, driving the first rack 562 to move and compress the second spring 563. Then, when the push plate 42 moves downward, the turntable 54 loses the resistance to reverse push. At this time, the elastic force of the second spring 563 resets and pushes the first rack 562 to move to the reset position, which can drive the first gear 561 to rotate to the reset position, causing the guide wheel 551 to move inward and drive the turntable 54 to rotate forward, causing the push plate 42 to retract inward with the bottleneck of the lacquerware 6, thereby forming a movement of adaptive horizontal movement of the push plate 42 as the curvature of the surface of the lacquerware 6 changes during the lifting process, so as to simulate the movement of a human hand close to the surface of the lacquerware 6.

[0028] The specific method of rotational connection between the sleeve 541 and the support platform 11 can be that the first bearing 542 is adapted to be embedded and fixed in the support platform 11, the sleeve 541 is adapted to be embedded in the inner ring of the first bearing 542, the second bearing 543 is embedded in the sleeve 541, and the support column 2 is adapted to pass through the inner ring of the second bearing 543. The friction force of the rotation of the sleeve 541 can be reduced by the connection between the first bearing 542 and the second bearing 543. Furthermore, a shoulder can be provided on the sleeve 541, the outer diameter of which is larger than the outer diameter of the inner ring of the first bearing 542, and the shoulder abuts against the upper end of the inner ring of the first bearing 542. At the same time, a bearing can be assembled at the position of the sleeve 541 at the lower end of the first bearing 542 to limit the turntable 54 from being able to rise and fall relative to the support platform 11 along its axial direction and only being able to rotate.

[0029] The lower side of the first rack 562 can also be fixedly connected to the pull rod 57, which is L-shaped and extends downward from the base 1. By pulling the pull rod 57 under the base, the first rack 562 moves accordingly and compresses the spring. During the movement of the first rack 562, the first rack 562 can be driven to rotate and the push plate 42 can be driven to move outward to make room for taking and placing the lacquerware 6.

[0030] In this embodiment, the axial line of the roller 43 is arranged along the diameter direction of the support platform 11 , and the length of the roller 43 is not less than the sliding stroke of the sliding member 55 .

[0031] In this embodiment, the roller 43 is rotatably connected to the lower end of an adjustment sleeve. The lower end of the vertical rod 41 is inserted into the adjustment sleeve 44. The vertical rod 41 is provided with a row of adjustment holes 4101. The side of the adjustment sleeve 44 is provided with an adjustment bolt 441. The adjustment bolt 441 is inserted into one of the adjustment holes 4101 after passing through the adjustment sleeve 44. The height of the vertical rod 41 can be adjusted by sliding the vertical rod 41 relative to the adjustment sleeve 44, thereby changing the height of the push plate 42, so that the push plate 42 can adapt to the polishing operation of lacquerware 6 of different heights. In a specific implementation, the lower end of the support column 2 can also be mounted on a sleeve (not shown in the drawings). The connection between the support column 2 and the sleeve is similar to the connection between the vertical rod 41 and the adjustment sleeve 44, forming a height-adjustable structure. The first motor 21 then drives the sleeve to rotate, driving the support column 2 after the height is adjusted.

[0032] In this embodiment, a circle of recessed limiting grooves 5101 is provided on the outer periphery of the transmission ring 51, and a number of connecting seats 52 distributed around the transmission ring 51 are connected to the base 1, and each connecting seat 52 is rotatably connected to a limiting wheel 521, and the limiting wheel 521 is adapted to be embedded in the limiting groove 5101; and each limiting wheel 521 surrounds the outside of the transmission ring 51 to form a restriction on the transmission ring 51, so that the transmission ring 51 and the support column are coaxial.

[0033] In this embodiment, a gear ring 511 is provided on the inner periphery of the transmission ring 51 , a second motor 53 is mounted on the base 1 , and an output shaft of the second motor 53 is connected to a second gear 531 meshing with the gear ring 511 .

[0034] In this embodiment, a protective cover 14 can also be fixed on the base 1, which covers the pushing mechanism 4 and the transmission mechanism 5, and a strip-shaped clearance groove is set on the protective cover 14, so that the vertical rod 41 can pass through the clearance groove to protect the pushing mechanism 4 and the transmission mechanism 5.

[0035] In addition, a control system may be configured, which may be a PLC controller for controlling the operation of the first motor 21 , the second motor 53 and the two lifting mechanisms 3 .

[0036] The working method of the lacquerware polishing device of the present invention is as follows: Pull out each push plate 42, specifically by pulling the pull rod 57 under the base, then place the lacquerware 6 upside down on the support column 2, so that the lacquerware 6 is sleeved on the upper end of the support column 2, and the support column 2 supports the inner bottom surface of the lacquerware 6. Then, swing the swing arm 22 until the vertical screw 23 is directly above the lacquerware 6, and rotate the vertical screw 23 downward to press the lacquerware 6 on the pressing plate 231, so that the lacquerware 6 can be fixed relative to the support column 2, and then release the push plates 42 so that each push plate 42 clamps the lacquerware 6; Control the support column 2 to rotate, so that the lacquerware 6 is suspended and rotated on the center of the support platform 11; The nozzle 33 connected to the oil tank sprays oil onto the paint ware 6, and the lifting mechanism 3 drives the nozzle 33 to move up and down relative to the paint ware 6, so that the oil is sprayed on the surface of the paint ware 6, forming an oiling operation process; The nozzle 33 connected to the powder box sprays the polishing powder onto the lacquerware 6, and the lifting mechanism 3 drives the nozzle 33 to move up and down relative to the lacquerware 6, and the polishing powder is sprayed on the surface of the lacquerware 6, forming a powder sprinkling operation process; The rotation of the transmission ring 51 drives each pushing part 512 to rotate with the support column 2 as the axis. During the process, the roller 43 moves up and down with the slope on both sides of the pushing part 512, thereby driving the vertical rod 41 and the push plate 42 to move up and down, thereby driving the sandpaper 421 to rise and fall relative to the lacquerware 6, forming the sandpaper 421 moving up and down on the surface of the lacquerware 6, forming an operating process of evenly applying vegetable oil, rubbing the polishing powder and the paint surface smooth, and polishing the paint surface. At this time, under the elastic force of the torsion of the turntable 54, the push plate 42 moves inward and outward adaptively with the curved surface of the lacquerware 6 during the process of rising and falling, and the lacquerware 6 keeps rotating during this process, so that the sandpaper 421 can perform polishing operations on various positions on the surface of the lacquerware 6.

[0037] As can be seen from the above working method, the present invention integrates the process steps of oil spraying, powder sprinkling and polishing in the polishing process of lacquerware 6. The lifting mechanism 3 sprays oil and powder to the lacquerware 6 through the nozzle 33, and the transmission mechanism 5 rotates through the transmission ring 51, so that the vertical rod 41 of the polishing mechanism 4 moves up and down along the slope on both sides of the push portion 512, thereby driving the sandpaper 421 fixed by the push plate 42 to move vertically on the surface of the lacquerware 6. At the same time, the elastic force of the torsion of the turntable 54 causes the push plate 42 to move horizontally inside and outside the curved surface of the lacquerware 6, thereby adaptively adhering to the surface of the lacquerware 6 with different curvatures, and during this process, the lacquerware 6 keeps rotating, so that the sandpaper 421 can perform polishing operations on various positions on the surface of the lacquerware 6. It can be seen that the present invention can realize the operation of multiple process steps on the lacquerware 6, which is more labor-saving and convenient than the manual polishing method.

[0038] Example 2: Figure 16 As shown, this embodiment differs from the first embodiment in that the structure of the elastic moving device is simplified. The elastic moving device employs a first spring 45, which connects the upper end of the vertical rod 41 to the push plate 42. The first spring 45 ensures that the sandpaper 421 adheres tightly to the surface of the lacquerware 6, enhancing the polishing effect.

[0039] In this embodiment, the sliding member 55 does not need to be slidably connected to the support platform. The sliding member 55 is directly fixedly connected to the support platform. The outward end of the sliding member 55 is provided with a guide hole 5501 for the vertical rod 41 to pass through and slide with it.
