Technical Field

[0001] The present invention relates to the technical field of furniture production, in particular to a surface polishing device for producing wooden furniture. Background Art

[0002] Fine processing on the surface of the wooden board structure of wooden furniture is a traditional furniture processing method in my country. By carving on the surface of the wooden board, the aesthetics and economic added value of the furniture can be greatly improved. Since the wooden material itself is prone to produce a large number of burrs after carving, it needs to be polished during the production process to remove burrs, rust, oil stains, dust, etc. on the surface of the board, while making the furniture lines smooth, the surface flat and smooth, the texture clear, and the feel smooth and comfortable. The existing furniture polishing equipment has a single polishing method and cannot meet the different working conditions of various furniture.

[0003] For example, Chinese patent (CN221159773U) discloses a furniture board polishing device for furniture production, including a polishing machine base, wherein two front and rear side clamps are arranged inside the polishing machine base, wherein the front and rear side clamps on the rear side are fixed to the inner wall of the polishing machine base, and the side surfaces of the front and rear side clamps at the front position are rotatably mounted with a rotating shaft 1, and the end of the rotating shaft 1 is fixedly mounted with a threaded rod, and the threaded rod is threadedly mounted on the polishing machine base and the end of the threaded rod is fixed with a knob 1, and the inner walls of the front and rear side clamps are rotatably mounted with two rotating shafts 2, and a bidirectional lead screw 1 is fixedly mounted between the two rotating shafts 2, and the outer surfaces of the two sections of the thread of the bidirectional lead screw 1 are threadedly mounted with left and right side clamps, and a knob 2 is fixed to one of the two ends of the rotating shaft, and the side surfaces of the front and rear side clamps are provided with passages for the left and right side clamps to move. One, a cylinder is fixedly installed on the inner wall of the grinder seat, and a frame is fixedly installed on the end of the piston rod of the cylinder, and two mounting seats are provided in the frame, and a grinding roller is rotatably installed in the mounting seat, and a grinding motor with an output shaft fixedly connected to the end of the grinding roller is fixedly installed on the side of the mounting seat, and a channel 2 for the mounting seat to move up and down is opened on the side of the frame, and a sliding plate is fixedly installed on the side of the mounting seat, and a channel 3 for the sliding plate to move up and down is opened on the side of the frame, four fixed plates are fixedly installed on the side of the frame, and a rotating shaft 3 is rotatably installed on the fixed plate, and a two-way screw 2 is fixedly installed between the two rotating shafts 3 on the same side, and the two sliding plates on the same side are respectively threadedly installed on the two sections of the threaded outer surface of the two-way screw 2 on the same side, and a knob 3 is fixed on the end of one of the rotating shafts 3.

[0004] The above patent uses a two-way lead screw to adjust the distance between the upper and lower grinding rollers, and performs simultaneous grinding operations on the upper and lower sides of the furniture board, thereby improving the grinding efficiency; since the grinding roller is set in the mounting seat, it can only move up and down to grind the upper and lower sides of the furniture board. The grinding method is relatively simple, and the grinding direction of the grinding roller cannot be adjusted according to needs. In addition, a large amount of debris will be generated during the grinding process, and the grinding debris cannot be collected, causing air pollution and harming people's health.

DETAILED DESCRIPTION

[0037] Refer to the following Figures 1 to 13 The embodiments of the present invention are described in detail. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0038] A surface polishing device for wooden furniture production, such as Figure 1 、 Figure 2 、 Figure 7 、 Figure 8 、 Figure 12As shown, it includes a device body 1, which is a cavity structure with an upper end opening. Top brackets 2 are installed on the left and right top ends of the device body 1. The top bracket 2 is an inverted "U" structure and can slide back and forth along the device body 1. A reversing shell 3 is installed below the top bracket 2. The reversing shell 3 can move up and down. The lower end of the reversing shell 3 is a cavity structure. (The structure of the reversing shell 3 is shown in FIG. Figure 7 The cam 6 has two guide holes 5 formed on the top and bottom of the cam 6, and the guide holes 5 are connected to each other to form a circle, and the cam 6 has two guide holes 5 on the bottom and bottom, and the cam 6 has two guide holes 5 on the bottom. The cam 10 is provided with a plurality of rollers 6 and a plurality of intermediate rollers 9, and the cam 10 is provided with a plurality of rollers 6 and a plurality of intermediate rollers 9. When the plurality of rollers 6 and the intermediate rollers 9 are on the same plane, the lower end of the grinding belt 10 protrudes from the outer sides of the side rollers 6 and the intermediate rollers 9 for easy grinding. The side rollers 6 and the intermediate rollers 9 have the same specifications. The grinding belt 10 is made of existing suitable soft components, and the installation method of the grinding belt 10 can be selected according to needs. The front right side of the reversing shell 3 is connected to a vertical plate for sliding left and right. A driving motor is fixedly installed on the vertical plate. The rightmost side roller rotates and passes through the vertical plate. A moving gear is coaxially fixed on the rotating shaft of the driving motor. A driven gear is coaxially fixed on the corresponding side roller. The moving gear is meshed with the driven gear, and the moving gear and the driven gear are not interfered with by any components (the moving gear and the driven gear are not shown in the figure). The corresponding side roller can move the vertical plate left and right. The driving motor is connected to the controller and the power supply. (It should be noted that the position and direction of the components in this application are shown in FIG. Figure 1 for reference);

[0039] When grinding the flat surface of furniture boards, the operator places the furniture boards on the equipment body 1, drives the reversing assembly to move the middle roller 9 upward, and the side rollers 6 on the left and right sides move away from each other until the middle roller and the side rollers are on the same plane. Since the grinding belt 10 is wrapped around the outer sides of the multiple side rollers 6 and the middle roller 9, it will not separate from the side rollers 6 and the middle roller 9 during use;

[0040] Then the corresponding components push the reversing shell 3 to move downward gradually until the grinding belt 10 contacts the surface of the furniture board, and then the reversing shell 3 stops moving. The power is turned on, the controller starts the drive motor to rotate, the moving gear engages with the slave gear to rotate, and the multiple side rollers 6 and the middle roller 9 synchronously drive the grinding belt 10 to rotate. The grinding belt 10 is attached to the outside of the furniture board for grinding, which can smooth the surface of the board, remove defects and impurities, make the surface quality of the furniture more uniform and beautiful, and also increase the durability and corrosion resistance of the furniture, thereby improving the service life.

[0041] When grinding the groove surface of the furniture board, the driving reversing assembly moves the middle roller 9 downward. Due to the force of the grinding belt 10, the side rollers 6 on the left and right sides gradually approach each other until the middle roller 9 is moved to the appropriate position of the guide hole 8. At this time, the middle roller 9 is located below the side rollers 6.

[0042] Then the corresponding components push the reversing shell 3 to move downward gradually until the arc-shaped grinding belt 10 on the middle roller 9 moves into the groove. The power is turned on, the controller starts the drive motor to rotate, and the grinding belt 10 is attached to the groove surface for grinding. Grinding can make the groove surface smoother and more delicate, make the lines more fluid, and enhance the exquisiteness of the furniture.

[0043] By continuously changing the shape of the polishing belt 10 , it is possible to better adapt to the polishing needs of furniture, thereby increasing the diversity of the polishing device.

[0044] like Figure 12 、 Figure 13 As shown, the adjusting component includes a telescopic spring 11 and a telescopic limiting rod 12, which has a telescopic characteristic. A positioning block is rotatably installed on the outer end of each side roller on the left side, and the positioning block can slide left and right along the outside of the limiting bar 4. A fixed ear plate 13 is fixedly installed on the outer end of each positioning block, and a support shaft 14 is fixedly installed between every two fixed ear plates 13 on the left side, and a support shaft 14 is fixedly installed between every two fixed ear plates 13 on the right side, so that the multiple side rollers 6 on the same side become a whole, and positioning plates are fixedly installed on the outer ends of the left and right sides of the reversing shell 3 respectively, and a telescopic limiting rod 12 is fixedly installed on one end of each positioning plate, and the other end of each telescopic limiting rod 12 is fixedly installed on the fixed ear plate 13 on the edgemost side. (The installation position of the telescopic limiting rod 12 is fixedly installed on the outer end of the reversing shell 3. Figure 7 As shown in the figure), each limiting telescopic rod 12 is provided with a telescopic spring 11, one end of the telescopic spring 11 is fixedly connected to the corresponding positioning plate, and the other end is fixedly connected to the corresponding fixed ear plate 13. The specifications of the telescopic spring 11 are selected according to needs, and the telescopic spring 11 can play a tensioning role on the grinding belt 10, so that the grinding belt 10 is always kept in a tensioned state, thereby preventing the grinding belt 10 from shaking significantly during the grinding process;

[0045] When the groove of the furniture board is roughly sanded, the driving reversing assembly moves the middle roller 9 downward. Due to the force of the sanding belt 10, the side rollers 6 on the left and right sides gradually move closer to the guide block 7. At the same time, the limiting telescopic rod 12 gradually extends and the telescopic spring 11 is stretched until the middle roller 9 is moved to the appropriate position of the guide hole 8. The position of the middle roller 9 is adjusted to meet the sanding needs of the groove and the tension of the sanding belt 10 is maintained.

[0046] When the surface of the furniture needs to be polished, the driving reversing assembly moves the middle roller 9 upward. Due to the reset force of each telescopic spring 11, the side rollers 6 on the left and right sides gradually move away from the guide block 7. At the same time, the limiting telescopic rod 12 contracts until the middle roller and the side roller are in the same plane. By continuously changing the shape of the polishing belt 10, it can better adapt to the polishing needs of the furniture, improve the diversity of the polishing device, and enable the side rollers 6 to automatically reset.

[0047] like Figure 7 、 Figure 8 、 Figure 12 As shown, the reversing assembly includes a lifting screw rod 15 and a lifting shaft 16, and the front and rear ends of the middle roller are rotatably installed with a middle block respectively, and the middle block can slide up and down along the outside of the guide block 7, and the outer end of each middle block is fixedly installed with a positioning ear plate 17. The rear end of the reversing shell 3 is fixedly installed with a screw plate, and the lifting screw rod 15 is rotatably installed on the screw plate, and the lifting screw rod 15 is threadedly installed on the positioning ear plate 17 on the rear side. The front end of the reversing shell 3 is fixedly installed with a shaft plate, and the lifting shaft 16 is fixedly installed on the shaft plate. The lower end of the lifting shaft 16 slides up and down through the positioning ear plate 17 on the front side. Each limit bar 4 is provided with a vertical slot located on the left and right sides of the guide block 7, and an intercepting block 18 is detachably installed in each vertical slot. An intercepting roller 19 is rotatably installed between the two intercepting blocks 18 on the left, and an intercepting roller 19 is rotatably installed between the two intercepting blocks 18 on the right, and an inserting shaft 20 that passes through the limit bar 4 is installed in each vertical slot. An insertion eye is provided on the intercepting block 18, and the insertion shaft 20 is installed in the corresponding insertion eye.

[0048] When rough grinding the plane of the furniture board, unplug the two plug-in shafts 20, remove the intercepting roller 19, and make the bottom surface of the grinding belt 10 on the plane through observation or using measuring tools, so that the surface of the board can be ground and polished more smoothly;

[0049] When the groove is roughly ground, each intercepting block 18 is inserted into the corresponding vertical slot, and the insertion shaft 20 is inserted into the insertion eye. The intercepting block 18 is limited. At this time, the grinding belt 10 is located above the two intercepting rollers 19 and contacts the two intercepting rollers 19. The lifting screw 15 is rotated to move the corresponding positioning ear plate 17 downward, and the front positioning ear plate 17 slides along the lifting shaft 16. Due to the force of the grinding belt 10, the side rollers 6 on the left and right sides gradually move closer to the guide block 7. At the same time, the limiting telescopic rod 12 is extended and the telescopic spring 11 is stretched until the middle roller 9 is moved to the appropriate position of the guide hole 8, thereby adjusting the position of the middle roller 9 to meet the grinding needs of the groove. Due to the setting of the two intercepting rollers 19, the grinding belt 10 can always be kept in a tensioned state, avoiding the relaxation of the grinding belt 10 during use, thereby improving the stability of grinding.

[0050] like Figure 1 、 Figure 5 、 Figure 7 、 Figure 11 As shown, a fixing cover 21 is fixedly installed on the top of the top bracket 2, and the fixing cover 21 is an inverted "U" structure. A lifting telescopic rod 22 is fixedly installed on the fixing cover 21. The lifting telescopic rod 22 is an electric telescopic rod and is connected to the controller and power supply. A through hole is provided on the top bracket 2, and the lifting telescopic rod 22 is arranged in the through hole. Vertical external holes are respectively provided at the left and right ends of the top bracket 2. A lifting beam 23 is installed at the bottom of the top bracket 2, and a limiting block is fixedly installed at both ends of the lifting beam 23. Each limiting block is slidably installed in the corresponding external hole up and down, and an external plate 24 is fixedly installed on the top of the lifting beam 23. An inner cavity is provided on the external plate 24, and the telescopic end of the lifting telescopic rod 22 is fixedly connected to the top of the external plate 24. A built-in reciprocating screw 25 located in the inner cavity is rotatably installed on the external plate 24, and a slider 26 is threadedly installed on the built-in reciprocating screw 25. The block 26 is installed in the inner cavity for sliding left and right, and a long hole in the left and right direction is opened on the lifting beam 23. The lower end of the slider 26 is fixedly installed with a sliding rod located in the long hole, and the sliding rod can slide left and right along the long hole. The lower end of the slide rod is fixedly installed with a sliding round block 27, and the lower end of the sliding round block 27 is fixedly installed with a positioning round block 28. A reversing round block 29 is fixedly installed in the middle of the top of the reversing shell 3, and the top of the reversing round block 29 is rotatably connected to the bottom end of the positioning round block 28. A positioning plug 30 that slides up and down is installed on the positioning round block 28. A plurality of sockets are evenly arranged on the top of the reversing round block 29, and the plurality of sockets form a circular structure. The positioning plug 30 is inserted in the corresponding sockets to realize the positioning of the reversing round block 29. An adjusting motor is fixedly installed at one end of the external plate 24. The rotating shaft of the adjusting motor is coaxially fixedly connected to the built-in reciprocating screw 25, and the adjusting motor is connected to the power supply and the controller;

[0051] When the power is turned on, the controller starts the regulating motor to rotate the built-in reciprocating screw 25. The built-in reciprocating screw 25 drives the slider 26, the sliding block 27, the positioning block 28, and the reversing block 29 to reciprocate left and right, so that the grinding belt 10 grinds the furniture board during the reciprocating motion, thereby improving the grinding efficiency and reducing the operation of the personnel. The reversing housing 3 will not hit the top bracket 2 during the left and right motion. The specifications of the built-in reciprocating screw 25 can be selected according to needs.

[0052] When adjusting the direction of the reversing shell 3, the positioning rod 30 is driven upward and pulled out from the socket, and the reversing block 29 is rotated to adjust the angle of the reversing shell 3. Then the positioning rod 30 is inserted into the corresponding socket to position the reversing shell 3, thereby improving stability to meet the needs of various grinding angles.

[0053] like Figure 1 、 Figure 6 、 Figure 4The top of the equipment body 1 is shown in FIG, , The top bracket 2 is slidably mounted on the equipment body 1 front and back, and two blocking blocks are fixedly mounted on the left end of the equipment body 1, and the top bracket 2 is arranged between the two blocking blocks. A displacement screw rod 31 is rotatably mounted between the two blocking blocks, and the displacement screw rod 31 is threadedly mounted on the top bracket 2. A crank is fixedly mounted on the front end of the displacement screw rod 31, and the rotation of the displacement screw rod 31 can move the top bracket 2 back and forth, thereby adjusting the grinding position. At the same time, the furniture board can also be polished during the front and back movement of the top bracket 2. The left and right top ends of the equipment body 1 are respectively fixed with fixed shells 32 in the front and back directions, and the two fixed shells 32 are arranged between the top bracket 2, and an adjustment slide plate 33 is slidably mounted between the two fixed shells 32. A placement frame 55 is fixedly mounted in the middle of the adjustment slide plate 33, and a wire mesh is fixedly mounted inside the placement frame 55. The left end of the placement frame 55 is provided with two limiting holes and the right end is provided with two limiting holes. Sliding rods 34 are slidably mounted in the two limiting holes on the left, and the right The two limit holes are respectively slidably mounted on the two sliding rods 34, and a clamping plate 35 is commonly fixedly mounted between the inner ends of the two sliding rods 34 on the same side. The two clamping plates 35 are arranged in the placement frame 55, and a push plate 36 is commonly fixedly mounted between the outer ends of the two sliding rods 34 on the same side. The two push plates 36 are arranged on the outside of the placement frame 55. Each sliding rod 34 is sleeved with an extrusion spring 37, and the extrusion spring 37 is arranged on the outside of the placement frame 55. One end of the extrusion spring 37 is fixedly connected to the corresponding push plate 36, and the other end is fixedly connected to the outer end of the placement frame 55. Normally, the two clamping plates 35 are arranged close to each other. A driving screw rod 38 is rotatably mounted in one of the fixed shells 32, and the driving screw rod 38 is threadedly mounted on the corresponding adjustment slide 33. The front end of the driving screw rod 38 is fixedly mounted with a crank handle. The front and rear ends of the placement frame 55 are respectively threadedly mounted with a plurality of top pressing screw rods, and the inner end of each top pressing screw rod is fixedly mounted with a top block. The number of top pressing screw rods is selected as needed. Two top pressing screw rods are provided here.

[0054] When sanding the furniture board, the crank is rotated to rotate the driving screw 38, thereby moving the adjustment slide 33 forward to the appropriate position, driving the two push plates 36 away from each other to the appropriate position, each extrusion spring 37 is stretched, and the person places the furniture board in the placement frame 55 and between the two clamping plates 35. The furniture board is higher than the end surface of the placement frame 55, and the two push plates 36 are released. Due to the resetting contraction force of the extrusion spring 37, the two clamping plates 35 quickly clamp the furniture board into position, and then the two top pressing screws are rotated to gradually approach the furniture board. The two top pressing screws clamp the front and rear end surfaces of the furniture board through the top block to prevent it from moving around during sanding;

[0055] After the furniture board is placed, the driving screw 38 is rotated in the reverse direction to move the adjustment slide 33 backward to the appropriate position, and then the subsequent grinding work is carried out. Since the two clamping plates 35 clamp and position the furniture board, it will not move during the grinding process, which improves the stability of the grinding and allows the furniture board to be quickly removed.

[0056] like Figure 1 、 Figure 4 As shown, a built-in filter 39 is fixedly installed in the top of the equipment body 1, and the adjustment slide 33 is arranged above the built-in filter 39. A cavity 40 is opened at the lower end of the equipment body 1, and a material receiving component is installed in the cavity 40.

[0057] like Figure 1 、 Figure 3 、 Figure 9 As shown, the material receiving assembly includes a material receiving box 41, which is slidably mounted in the cavity 40 back and forth. A blocking plate 42 is fixedly mounted inside the material receiving box 41, and a sealing net 43 is provided in the middle of the blocking plate 42 (the mesh inner diameters of the wire mesh and the built-in filter screen 39 are the same, and the mesh inner diameter of the sealing net 43 is smaller than the mesh inner diameter of the wire mesh). Two blocking plates are fixedly mounted between the sealing net 43 and the bottom end of the material receiving box 41, and the two blocking plates are arranged on the left and right sides of the sealing net 43. Feed openings 44 are respectively provided at the left and right ends of the blocking plate 42. Material storage boxes 45 are fixedly mounted on the left and right bottom ends of the material receiving box 41, and the material storage boxes 45 are arranged on one side of the blocking plate, and the material storage boxes 45 are arranged below the material feeding opening 44. An auger pipe with an upward opening is fixedly mounted in the storage box 45, and an inclined plate is fixedly mounted on both ends of the opening of each auger pipe. The material feeding opening 44 is arranged corresponding to the two inclined plates directly below, that is, the material feeding opening 44 and the material storage box 45 are connected.

[0058] like Figure 2 、 Figure 9As shown, two connecting blocks are fixedly installed in the rear end of the material receiving box 41, and a driving reciprocating screw 46 is rotatably installed between the two connecting blocks. Scrapers 47 are respectively threadedly installed on the left and right ends of the driving reciprocating screw 46. The scrapers 47 slide left and right along the blocking plate 42. Threads are respectively provided at both ends of the driving reciprocating screw 46. In the initial state, the two scrapers 47 are arranged close to each other and are located in the middle of the sealing net 43. A fan 48 is fixedly installed at the rear end of the material receiving box 41. The fan 48 is connected to the power supply and the controller. A driving gear 49 is coaxially fixed on the rotating shaft of the fan 48. The rear end of the material receiving box 41 is rotatably installed. The driven gear 50 is meshed with the driving gear 49, and the driven gear 50 is arranged above the driving gear 49. A bevel gear set 51 is installed on the driving reciprocating screw 46. The bevel gear set 51 includes two bevel gears, one of which is coaxially fixedly mounted on the driving reciprocating screw 46. The shaft of the driven gear 50 rotates and passes through the material receiving box 41. The other bevel gear is coaxially fixedly mounted on the shaft of the driven gear 50. The two bevel gears are meshed and connected. An exhaust pipe 54 is fixedly mounted on the exhaust port of the fan 48. The exhaust pipe 54 extends between the sealing net 43 and the material receiving box 41. A plurality of exhaust holes are provided on the exhaust pipe 54.

[0059] like Figure 2 、 Figure 10 As shown, a conveying auger 52 is rotatably installed in each auger tube, and the conveying auger 52 is arranged in contact with the inner wall of the auger tube. A crank handle is fixedly installed at the front end of each conveying auger 52, and an extrusion cylinder 53 is fixedly installed at the rear end of each receiving box 41. The auger tube and the extrusion cylinder 53 are arranged in a through-connected manner, and a discharge plate is bolted in the rear port of the extrusion cylinder 53 to facilitate the discharge of debris in the extrusion cylinder 53.

[0060] When the power is turned on, the controller starts the fan 48 to draw air outwards. The wood chips from the grinding process are blown by the wind through the wire mesh and the built-in filter 39 and enter the receiving box 41. Since the mesh of the sealing net 43 is relatively small, the wood chips will accumulate on the mesh surface of the sealing net 43, preventing the chips from floating into the air and affecting the air quality.

[0061] During the rotation of the fan 48, the driven gear 50 is engaged with the driving gear 49, and then the bevel gear set 51 drives the reciprocating screw 46 to rotate. Since the left and right ends of the driving reciprocating screw 46 are respectively provided with threads, the driving reciprocating screw 46 drives the two scrapers 47 to move away from and close to each other, thereby pushing the wood chips on the sealing net 43 into the corresponding feed port 44. The wood chips eventually fall onto the conveying auger 52. Since the feed port 44 has a slender strip structure, the wood chips will not be sucked out in the opposite direction.

[0062] When the sanding is finished, the power is turned off, the unloading plate is opened, and the driving rod crank drives the corresponding conveying auger 52 to rotate. During the rotation process, the conveying auger 52 can convey the wood debris into the extrusion cylinder 53 and finally discharge it into the external collection bag. People can use the wood debris to make other parts without affecting people's health. For example, if there are uncleaned wood debris remaining on the sealing net 43, people drive the receiving box 41 to slide out of the cavity 40 and clean the debris on the sealing net 43.
