Description

Technical Field

[0001] The invention relates to the technical field of polishing of decorative panels, and in particular to a polishing device for producing decorative panels and a use method thereof. Background Art

[0002] Common veneers are divided into natural wood veneer veneers and artificial rosewood veneers. The difference in appearance between artificial veneer and natural wood veneer is that the texture of the former is basically straight or regular, while the latter is a natural wood pattern with natural texture pattern, large variability and irregularity. When producing and processing veneers, they often need to be polished. Polishing refers to a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of the workpiece to obtain a bright and flat surface. It is a modification of the workpiece surface using polishing tools and abrasive particles or other polishing media. Usually a polishing wheel is used as a polishing tool. When performing polishing work, it is often necessary to cooperate with polishing agents. Polishing agents (commonly known as brighteners): light yellow or yellow transparent liquid preparations. Preparations for different materials are constantly evolving according to market demand.

[0003] At present, two polishing methods are usually used when polishing veneer panels: 1. The veneer panel is placed flat on the workbench, and the staff holds a handheld polishing machine to polish the surface of the veneer panel. During the polishing process, the polishing is paused and polishing agent is applied to the surface of the veneer panel to assist polishing; 2. Polishing is performed using a high-speed rotating polishing roller, which usually requires the cooperation of two people. Each person holds one end of the veneer panel, and the rapidly rotating polishing roller is placed between the two people. The two people pull the veneer panel left and right in a "sawing" manner and rub it in contact with the polishing roller. After working for a period of time, it is necessary to pause the rotation of the polishing wheel and add polishing agent to the polishing roller to assist polishing.

[0015] A method for using a polishing device for producing a veneer panel comprises the following steps: S1. First, according to the size of the veneer to be polished, the working height of the polishing machine, the distance between the two adjacent upper and lower pressure rollers, and the clamping distance between the two adjacent front and rear rollers are adjusted. Specifically, by rotating the adjusting screw rod, the adjusting screw rod can adjust the height of the lifting seat, so that the distance between the lifting seat and the fixed seat and the angle between the two connecting rods can be adjusted, so that the distance between the upper and lower pressure rollers can be adjusted according to the thickness of the plate, and the working height of the polishing machine can be adjusted according to the thickness of the plate by rotating the threaded rod. The bidirectional screw is rotated by the turntable, so that the distance between the two translation plates can be adjusted according to the width of the plate, so that the roller can well constrain and guide the plate; S2, then, turn on the power supply and start the motor. The motor drives the disc to rotate through its output shaft. The disc drives the pushing column to revolve through the rotating frame. The pushing column pushes the movable frame. Under the limiting action of the two reciprocating rods, the movable frame drives the polishing machine to move back and forth, so that the polishing machine can reciprocate and polish the surface of the plate. S3. When the reciprocating rod moves back and forth, the tooth block provided on one of the reciprocating rods can mesh with the driving gear for transmission, that is, when the reciprocating rod is pushed forward, the tooth block and the movable cavity are squeezed and will not rotate. At this time, the driving gear can be rotated counterclockwise through the tooth block, and the driving gear drives the second bevel gear to rotate counterclockwise through the telescopic shaft, and the second bevel gear can drive the second pulley to rotate counterclockwise through the first bevel gear. Under the action of the transmission belt, the first pulley drives the second transmission gear to rotate counterclockwise. Under the action of the first pinion, the second pinion, the third pinion, the fourth pinion and the connecting rod, the first transmission gear can rotate synchronously with the second transmission gear in opposite directions, so that the upper and lower pressure rollers can rotate synchronously in opposite directions to extrude and convey the veneer to be polished. When the reciprocating rod moves backward and the tooth block is squeezed with the driving gear, the tooth block flips through the rotating shaft to tighten the torsion spring, so that the reciprocating rod will not cause the driving gear to rotate when it moves backward, thereby realizing intermittent conveying of the veneer to be polished. S4. The telescopic shaft is set so that when the working height of the polishing machine is adjusted through the transmission mechanism, the star-shaped shaft can slide inside the lower shaft, and the distance between the upper shaft and the lower shaft can be adjusted accordingly, ensuring that when the polishing machine works at different heights, the linkage mechanism can transmit the transmission between the transmission mechanism and the transmission mechanism; S5. During the reciprocating process of the other reciprocating rod, the reciprocating rod can pull the traction rope when it retracts, and the traction rope pulls up the piston, compressing the reset spring. At this time, the one-way valve inside the one-way valve tube connected to the first infusion tube opens, and the one-way valve inside the one-way valve tube connected to the second infusion tube closes, so that the polishing agent stored in the liquid tank can be pumped into the vertical cylinder. Afterwards, when the reciprocating rod is extended, the piston moves down and resets under the action of the reset spring. At this time, the one-way valve inside the one-way valve tube connected to the first infusion tube is closed. The valve is closed, and the one-way valve inside the one-way valve tube connected to the second infusion tube is opened, so that the polishing agent collected inside the vertical cylinder can be transported to the inside of the hollow tube through the second infusion tube, transported to the inside of the connecting tube through the hollow tube, and transported to the inside of the cavity through the connecting tube. As the pressure inside the cavity increases, the polishing agent inside the cavity will flow out through the micropores, and the pressure roller is used to squeeze and transport the veneer to be polished, so that the outflowing polishing agent can be equidistantly placed at different positions on the surface of the veneer to be polished, thereby assisting the polishing machine to polish the outer wall of the veneer to be polished; S6. When the spacing between the two adjacent upper and lower pressing rollers is adjusted according to the thickness of the decorative panel to be polished, the pressing roller can drive the guide block to slide accordingly on the inner side of the fixed guide frame through the connecting tube and the hollow tube, and the connecting tube and the guide block are rotationally connected, and the guide block is slidingly connected to the fixed guide frame, so that the second infusion tube can stably transport the polishing agent to the inside of the hollow tube.

[0016] The working principle and beneficial effects of the present invention are: In the present invention, the transmission mechanism is set up so that the motor drives the disc to rotate through its output shaft, and the disc drives the pushing column to revolve through the rotating frame, and the pushing column pushes the movable frame. Under the limiting action of the two reciprocating rods, the movable frame drives the polishing machine to move back and forth, so that the polishing machine can reciprocate and polish the surface of the plate. While the reciprocating rods are moving back and forth, the tooth block set on one of the reciprocating rods can intermittently mesh with the driving gear, and the driving gear drives the second bevel gear to rotate counterclockwise through the telescopic shaft. Under the action of the first bevel gear, the second pulley, and the transmission belt, the first pulley can drive the transmission mechanism, so that the upper and lower pressure rollers can rotate synchronously in opposite directions to extrude and transmit the veneer to be polished, and then the reciprocating polishing of the polishing machine and the intermittent transmission of the veneer to be polished are realized through a single drive, which has a high use value; In the present invention, during the reciprocating process of the other reciprocating rod, the traction rope can be pulled and relaxed. Under the joint action of the piston, the return spring, the first infusion tube, the one-way valve tube, the second infusion tube, the liquid tank, the vertical tube and other structures, the polishing agent collected in the vertical tube can be intermittently transported to the inside of the hollow tube through the second infusion tube, transported to the inside of the connecting tube through the hollow tube, and transported to the inside of the cavity through the connecting tube. As the pressure inside the cavity increases, the polishing agent inside the cavity will flow out through the micropores, and the pressure roller is used to squeeze and transport the veneer to be polished, so that the outflowing polishing agent can be equidistantly placed at different positions on the surface of the veneer to be polished, thereby assisting the polishing machine to polish the outer wall of the veneer to be polished. The present invention has simple operation, strong linkage, diversified functions, high degree of automation, greatly improved polishing efficiency, broad application prospects, and significant progress in the field of veneer processing. In the present invention, the working height of the polishing machine, the distance between two upper and lower adjacent pressing rollers, and the clamping distance between two front and rear adjacent rotating rollers can be adjusted according to the size of the veneer to be polished, and the present invention has good applicability. In the present invention, when the spacing between the two adjacent pressing rollers is adjusted according to the thickness of the veneer to be polished, the pressing roller can drive the guide block to slide correspondingly inside the fixed guide frame through the connecting tube and the hollow tube, and the connecting tube is rotatably connected to the guide block, and the guide block is slidably connected to the fixed guide frame, so that the second infusion tube can stably transport the polishing agent into the hollow tube without rotational distortion. In the present invention, the arrangement of the telescopic shaft enables the star-shaped shaft to slide inside the lower shaft during the process of adjusting the working height of the polishing machine through the transmission mechanism, and the distance between the upper shaft and the lower shaft can be adjusted accordingly, thereby ensuring that when the polishing machine works at different heights, the linkage mechanism can transmit the power between the transmission mechanism and the transmission mechanism.

[0032] Specifically, the polishing agent adding mechanism 8 includes a fixed frame 81 installed on the bottom support frame 1, the top of the fixed frame 81 is rotatably connected to a pulley 84, the bottom end of the fixed frame 81 is fixedly connected to a bottom plate 82, a liquid tank 83 containing polishing agent is placed on the upper side of the bottom plate 82, a liquid adding component 86 is arranged on the upper side of the bottom plate 82, and a bracket 85 for supporting the liquid adding component 86 is fixedly connected to the top of the bottom plate 82.

[0033] Furthermore, the liquid adding component 86 includes a vertical cylinder 862 fixedly mounted on the inner side of the bracket 85, a piston 864 is slidably mounted on the inner side of the vertical cylinder 862, a return spring 863 is fixedly connected between the top of the piston 864 and the top of the vertical cylinder 862, a traction rope 861 is connected to the top of the piston 864, the traction rope 861 slides through the top of the vertical cylinder 862, and the other end of the traction rope 861 is connected to one of the reciprocating rods 78.

[0034] Furthermore, a one-way valve tube 865 connected to the interior of the vertical cylinder 862 is provided on both sides of the bottom of the vertical cylinder 862, and a one-way valve is provided on the two one-way valve tubes 865. One of the one-way valve tubes 865 is connected to the liquid tank 83 through the first infusion tube 866, and the other one-way valve tube 865 is connected to the hollow tube 378 through the second infusion tube 867.

[0035] In the present embodiment, during the reciprocating process of the reciprocating rod 78, the reciprocating rod 78 can pull the traction rope 861 when it retracts, and the traction rope 861 pulls up the piston 864, so that the reset spring 863 is compressed. At this time, the one-way valve inside the one-way valve tube 865 connected to the first infusion tube 866 is opened, and the one-way valve inside the one-way valve tube 865 connected to the second infusion tube 867 is closed, so that the polishing agent stored in the liquid tank 83 can be pumped into the vertical cylinder 862. Afterwards, when the reciprocating rod 78 is extended, under the action of the reset spring 863, the piston 864 moves down and resets. At this time, the one-way valve inside the one-way valve tube 865 connected to the first infusion tube 866 is closed, and the one-way valve inside the one-way valve tube 865 connected to the second infusion tube 867 is closed. The one-way valve inside the one-way valve tube 865 is opened, so that the polishing agent collected inside the vertical cylinder 862 can be transported to the inside of the hollow tube 378 through the second infusion tube 867, transported to the inside of the connecting tube 379 through the hollow tube 378, and transported to the inside of the cavity 375 through the connecting tube 379. As the pressure inside the cavity 375 increases, the polishing agent inside the cavity 375 will flow out through the micropores 374 (according to the width of the decorative panel 5 to be polished, the unworking micropores 374 can be blocked by a threaded plug), and the pressure roller 371 is used to extrude and transport the decorative panel 5 to be polished, so that the outflowing polishing agent can be equidistantly placed at different positions on the surface of the decorative panel 5 to be polished, thereby assisting the polishing machine 9 to polish the outer wall of the decorative panel 5 to be polished. Example

[0036] See also Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 , Fig. 9 as well as Fig.10 A polishing device for producing decorative panels includes all the contents of Example 3. In addition, it also includes a linkage mechanism 4 arranged between the transmission mechanism 3 and the transmission mechanism 7. While the transmission mechanism 7 reciprocates the polisher 9 left and right, the transmission mechanism 3 can be intermittently driven by the linkage mechanism 4, so that the decorative panel 5 to be polished can be intermittently transported.

[0037] Specifically, the linkage mechanism 4 includes a first bevel gear 44 rotatably connected to the truss 12, a second bevel gear 45 is meshedly connected to the upper side of the first bevel gear 44, a right-angle plate 49 is rotatably connected between the first bevel gear 44 and the second bevel gear 45, the right-angle plate 49 is fixed to the outer wall of the truss 12, a hanging plate 48 is fixed to the side wall of the U-shaped frame 71, a driving gear 47 is rotatably connected to the bottom of the hanging plate 48, a telescopic shaft 46 is connected between the driving gear 47 and the second bevel gear 45, the telescopic shaft 46 includes an upper shaft 461 fixed to the bottom end of the driving gear 47 and a lower shaft 463 fixed to the top end of the second bevel gear 45, the lower shaft 463 is rotatably connected to the right-angle plate 49, a star shaft 462 is fixed to the bottom end of the upper shaft 461, the star shaft 462 extends to the inside of the lower shaft 463 and is slidably connected thereto.

[0038] Furthermore, the linkage mechanism 4 also includes a second pulley 42 fixedly connected to the outer wall of the first bevel gear 44 and a first pulley 41 fixedly connected to the outer wall of the second transmission gear 366 , and a transmission belt 43 is connected between the first pulley 41 and the second pulley 42 .

[0039] Furthermore, an active cavity 781 is provided on the outer wall of the reciprocating rod 78 located on one side of the driving gear 47, and a tooth block 782 extending out of the active cavity 781 and cooperating with the driving gear 47 is distributed on the inner wall of the active cavity 781. The hole provided inside the U-shaped frame 71 for the reciprocating rod 78 to slide will not interfere with the tooth block 782. One side of the tooth block 782 abuts against the active cavity 781, and the other side of the tooth block 782 is rotatably connected to the active cavity 781 through a rotating shaft 784, and a torsion spring 783 is connected between the rotating shaft 784 and the active cavity 781.

[0040] In this embodiment, while the reciprocating rod 78 is moving back and forth, the tooth block 782 provided on one of the reciprocating rods 78 can be meshed with the driving gear 47 for transmission, that is, when the reciprocating rod 78 is pushed forward, the tooth block 782 is squeezed by the movable cavity 781 and will not rotate. At this time, the driving gear 47 can be rotated counterclockwise through the tooth block 782, and the driving gear 47 drives the second bevel gear 45 to rotate counterclockwise through the telescopic shaft 46. The second bevel gear 45 can drive the second pulley 42 to rotate counterclockwise through the first bevel gear 44. Under the action of the transmission belt 43, the first pulley 41 drives the second transmission gear 366 to rotate counterclockwise.

[0041] Working principle and usage process: First, according to the size of the decorative panel 5 to be polished, the working height of the polishing machine 9, the distance between the two adjacent upper and lower pressure rollers 371, and the clamping distance between the two adjacent front and rear rollers 24 are adjusted. Specifically, by rotating the adjusting screw 35, the adjusting screw 35 can adjust the height of the lifting seat 32, so that the distance between the lifting seat 32 and the fixed seat 31 and the angle between the two connecting rods 367 can be adjusted, so that the distance between the upper and lower pressure rollers 371 can be adjusted according to the thickness of the plate. By rotating the threaded rod 76, the working height of the polishing machine 9 can be adjusted according to the thickness of the plate. By rotating the bidirectional screw 22 through the turntable 21, the distance between the two translation plates 23 can be adjusted according to the width of the plate, so that the roller 24 can constrain and guide the plate well.

[0042] Next, turn on the power supply and start the motor 74. The motor 74 drives the disc 721 to rotate through its output shaft. The disc 721 drives the pushing column 723 to revolve through the rotating frame 722. The pushing column 723 pushes the movable frame 77. Under the limiting action of the two reciprocating rods 78, the movable frame 77 drives the polishing machine 9 to move back and forth, so that the polishing machine 9 can reciprocate and polish the surface of the plate.

[0043] When the reciprocating rod 78 reciprocates, the tooth block 782 provided on one of the reciprocating rods 78 can mesh with the driving gear 47 for transmission. That is, when the reciprocating rod 78 is pushed forward, the tooth block 782 is squeezed by the movable cavity 781 and does not rotate. At this time, the driving gear 47 can be rotated counterclockwise through the tooth block 782. The driving gear 47 drives the second bevel gear 45 to rotate counterclockwise through the telescopic shaft 46. The second bevel gear 45 can drive the second pulley 42 to rotate counterclockwise through the first bevel gear 44. Under the action of the transmission belt 43, the first pulley 41 drives the second transmission gear 366 to rotate counterclockwise. Under the action of the wheel 361, the second pinion 362, the third pinion 363, the fourth pinion 364 and the connecting rod 367, the first transmission gear 365 can rotate synchronously with the second transmission gear 366 in opposite directions, so that the upper and lower pressure rollers 371 can rotate synchronously in opposite directions to extrude and convey the polished decorative panel 5. When the reciprocating rod 78 moves backward and the tooth block 782 is squeezed by the driving gear 47, the tooth block 782 is flipped through the rotating shaft 784 to tighten the torsion spring 783, so that the reciprocating rod 78 will not cause the driving gear 47 to rotate when moving backward, thereby realizing intermittent conveying of the polished decorative panel 5.

[0044] The setting of the telescopic shaft 46 enables the star-shaped shaft 462 to slide inside the lower shaft 463 during the process of adjusting the working height of the polishing machine 9 through the transmission mechanism 7, and the distance between the upper shaft 461 and the lower shaft 463 can be adjusted accordingly, ensuring that when the polishing machine 9 works at different heights, the linkage mechanism 4 can transmit the power between the transmission mechanism 7 and the transmission mechanism 3.

[0045] During the reciprocating process of the other reciprocating rod 78, the reciprocating rod 78 can pull the traction rope 861 when it retracts, and the traction rope 861 pulls up the piston 864, so that the reset spring 863 is compressed. At this time, the one-way valve inside the one-way valve tube 865 connected to the first infusion tube 866 is opened, and the one-way valve inside the one-way valve tube 865 connected to the second infusion tube 867 is closed, so that the polishing agent stored in the liquid tank 83 can be pumped into the vertical cylinder 862. Afterwards, when the reciprocating rod 78 is extended, under the action of the reset spring 863, the piston 864 moves down and resets. At this time, the one-way valve inside the one-way valve tube 865 connected to the first infusion tube 866 is closed. The valve is closed, and the one-way valve inside the one-way valve tube 865 connected to the second infusion tube 867 is opened, so that the polishing agent collected inside the vertical cylinder 862 can be transported to the inside of the hollow tube 378 through the second infusion tube 867, transported to the inside of the connecting tube 379 through the hollow tube 378, and transported to the inside of the cavity 375 through the connecting tube 379. As the pressure inside the cavity 375 increases, the polishing agent inside the cavity 375 will flow out through the micropores 374, and the pressure roller 371 is used to extrude and transport the decorative panel 5 to be polished, so that the outflowing polishing agent can be equidistantly placed at different positions on the surface of the decorative panel 5 to be polished, thereby assisting the polishing machine 9 to polish the outer wall of the decorative panel 5 to be polished.

[0046] When the spacing between the two adjacent upper and lower pressing rollers 371 is adjusted according to the thickness of the decorative panel 5 to be polished, the pressing roller 371 can drive the guide block 377 to slide accordingly on the inner side of the fixed guide frame 376 through the connecting tube 379 and the hollow tube 378, and the connecting tube 379 and the guide block 377 are rotatably connected, and the guide block 377 is slidably connected to the fixed guide frame 376, so that the second infusion tube 867 can stably transport the polishing agent to the inside of the hollow tube 378.

First, according to the size of the veneer panel (5) to be polished, the working height of the polishing machine (9), the distance between the two upper and lower adjacent pressure rollers (371), and the clamping distance between the two front and rear adjacent rotating rollers (24) are adjusted. Specifically, by rotating the adjusting screw rod (35), the adjusting screw rod (35) can adjust the height of the lifting seat (32), so that the distance between the lifting seat (32) and the fixed seat (31) and the angle between the two connecting rods (367) can be adjusted, so that the distance between the upper and lower pressure rollers (371) can be adjusted according to the thickness of the plate. By rotating the threaded rod (76), the working height of the polishing machine (9) can be adjusted according to the thickness of the plate. By rotating the bidirectional screw rod (22) through the turntable (21), the distance between the two translation plates (23) can be adjusted according to the width of the plate, so that the rotating roller (24) can well constrain and guide the plate; S2, then, the power supply is turned on and the motor (74) is started. The motor (74) drives the disc (721) to rotate through its output shaft. The disc (721) drives the pushing column (723) to revolve through the rotating frame (722). The pushing column (723) pushes the movable frame (77). Under the limiting action of the two reciprocating rods (78), the movable frame (77) drives the polishing machine (9) to move back and forth, so that the polishing machine (9) can reciprocate and polish the surface of the plate. S3. When the reciprocating rod (78) is reciprocating, a tooth block (782) provided on one of the reciprocating rods (78) can be meshed with the driving gear (47) for transmission, that is, when the reciprocating rod (78) is pushed forward, the tooth block (782) is squeezed with the movable cavity (781) and does not rotate. At this time, the driving gear (47) can be rotated counterclockwise through the tooth block (782). The driving gear (47) drives the second bevel gear (45) to rotate counterclockwise through the telescopic shaft (46). The second bevel gear (45) can drive the second pulley (42) to rotate counterclockwise through the first bevel gear (44). Under the action of the transmission belt (43), the first pulley (41) drives the second transmission gear (366) to rotate counterclockwise. Under the action of the pinion (361), the second pinion (362), the third pinion (363), the fourth pinion (364) and the connecting rod (367), the first transmission gear (365) and the second transmission gear (366) can rotate synchronously in opposite directions, so that the upper and lower pressure rollers (371) can rotate synchronously in opposite directions to squeeze and convey the veneer panel (5) to be polished. When the reciprocating rod (78) moves backward and the tooth block (782) squeezes the driving gear (47), the tooth block (782) turns over through the rotating shaft (784) to tighten the torsion spring (783), so that the reciprocating rod (78) does not cause the driving gear (47) to rotate when moving backward, thereby achieving intermittent conveying of the veneer panel (5) to be polished; S4, the telescopic shaft (46) is arranged so that when the working height of the polishing machine (9) is adjusted by the transmission mechanism (7), the star-shaped shaft (462) can slide inside the lower shaft (463), and the distance between the upper shaft (461) and the lower shaft (463) can be adjusted accordingly, thereby ensuring that when the polishing machine (9) is working at different heights, the linkage mechanism (4) can transmit the power between the transmission mechanism (7) and the transmission mechanism (3); S5. During the reciprocating process of the other reciprocating rod (78), the reciprocating rod (78) can pull the traction rope (861) when it retracts, and the traction rope (861) pulls up the piston (864), so that the reset spring (863) is compressed. At this time, the one-way valve inside the one-way valve tube (865) connected to the first infusion tube (866) opens, and the one-way valve inside the one-way valve tube (865) connected to the second infusion tube (867) closes, so that the polishing agent stored in the liquid tank (83) can be pumped into the vertical cylinder (862). Afterwards, when the reciprocating rod (78) is extended, under the action of the reset spring (863), the piston (864) moves down and resets. At this time, the one-way valve inside the one-way valve tube (865) connected to the first infusion tube (866) is closed. The one-way valve is closed, and the one-way valve inside the one-way valve tube (865) connected to the second liquid delivery tube (867) is opened, so that the polishing agent collected inside the vertical cylinder (862) can be transported to the inside of the hollow tube (378) through the second liquid delivery tube (867), transported to the inside of the connecting tube (379) through the hollow tube (378), and transported to the inside of the cavity (375) through the connecting tube (379). As the pressure inside the cavity (375) increases, the polishing agent inside the cavity (375) flows out through the micropores (374), and the pressure roller (371) is used to squeeze and transport the veneer panel (5) to be polished, so that the polishing agent that flows out can be equidistantly placed at different positions on the surface of the veneer panel (5) to be polished, thereby assisting the polishing machine (9) in polishing the outer wall of the veneer panel (5) to be polished; S6. When the spacing between the two upper and lower adjacent pressing rollers (371) is adjusted according to the thickness of the veneer panel (5) to be polished, the pressing roller (371) can drive the guide block (377) to slide correspondingly inside the fixed guide frame (376) through the connecting tube (379) and the hollow tube (378), and the connecting tube (379) and the guide block (377) are rotationally connected, and the guide block (377) is slidably connected to the fixed guide frame (376), so that the second infusion tube (867) can stably transport the polishing agent to the inside of the hollow tube (378).
