Description

Technical Field

[0001] The invention relates to the technical field of plywood surface treatment, in particular to a high-efficiency plywood surface treatment device. Background Art

[0002] Plywood is one of the commonly used materials for furniture. Plywood is a three-layer or multi-layer plate material made by peeling wood segments into veneers or planing wood blocks into thin wood, and then gluing them with adhesive. Usually, an odd number of veneers are used, and the fibers of adjacent layers of veneers are glued perpendicular to each other. In the production process of plywood, polishing the edges of the plywood is an indispensable process. After polishing, the edges of the plywood can be made smooth and flat.

[0003] The invention patent with the existing patent announcement number CN117325044A discloses a double-sided grinding device for plywood, including a box body, a driving roller and a pressing roller; a plurality of driving rollers and pressing rollers are rotatably plugged in the box body; the plywood is placed on a conveyor belt, and then the first motor is powered on and rotated to drive the plywood to move to the bottom of the pressing plate, the pen-shaped cylinder is actuated to push the pressing plate down to press the plywood to complete the fixation, and then the second motor is powered on and rotated to drive the symmetrical threaded shaft to rotate precisely, thereby driving the two movable plates and the grinding parts to move symmetrically, thereby clamping the two sides of the plywood for grinding, and driven by the high-precision first motor, so that the two sides of the plywood can be accurately ground to the set width, so that the grinding efficiency is high and the precision is high.

[0027] 2. The present invention provides a high-efficiency surface treatment equipment for plywood. By setting a moving component, the grinding roller can be driven to move along the side of the plywood. At the same time, under the action of the rotating component, the grinding roller moves horizontally along the side of the plywood, and the lifting component can drive the grinding roller to perform reciprocating lifting and lowering motion.

[0030] 5. By setting up the telescopic component, while the lifting component lifts the plywood, the telescopic component can drive the four grinding rollers on the four sides to move, so that the four grinding rollers can be moved to the sides of the plywood and contact with the sides of the plywood, which is convenient for subsequent grinding work.

[0031] 6. By setting up a transmission component, the telescopic component can be driven to work through the transmission component while the jacking component is working, that is, the four grinding rollers can move toward the plywood and contact the plywood while the plywood moves upward. After grinding, when the jacking component drives the plywood to return downward, the four grinding rollers can move away from the plywood to prepare for the next grinding of the plywood. That is, by utilizing the transmission component, the jacking component and the telescopic component can achieve a linkage effect, which is beneficial to reduce the number of driving sources used in the equipment, reduce power consumption, and thus help reduce costs.

[0045] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0046] The present invention provides the following preferred embodiments:

[0047] Embodiment 1, as Figure 1-Figure 12 As shown, a plywood efficient surface treatment device includes a bottom plate 11, and a roller conveyor 12 for conveying plywood 55 is installed on the top of the bottom plate 11. The roller conveyor 12 can realize the transportation of the plywood 55, so as to realize the continuous operation of the plywood 55, which is beneficial to improve the efficiency of the side treatment of the plywood 55. The roller conveyor 12 also includes a lifting mechanism, a grinding mechanism and an adjustment mechanism;

[0048] The lifting mechanism includes two lifting components and a plurality of movable top plates 50. The plurality of movable top plates 50 are symmetrically arranged on both sides below the plywood 55. Each lifting component is located between the roller conveyor 12 and the plurality of movable top plates 50 on the same side. Specifically, each movable top plate 50 is located between two adjacent driving rollers, and the movable top plate 50 does not contact the driving roller. When the two lifting components work at the same time, the plurality of movable top plates 50 can be driven to rise at the same time, thereby pushing the plywood 55 to be lifted, so that the plywood 55 can be away from the roller conveyor 12, playing a role of avoidance, making it more convenient for the grinding mechanism to fully grind the sides of the plywood 55, and effectively avoiding the situation that the side of the plywood 55 in contact with the roller conveyor 12 is difficult to be grinded, which is conducive to reducing grinding dead angles.

[0049] The grinding mechanism includes a top frame 13, four grinding rollers 26, four moving frames 18, four second mounting plates 25, four groups of moving components, four groups of driving components, four groups of lifting components and four groups of rotating components. The top frame 13 is located above the roller conveyor 12 and is fixed to the top of the bottom plate 11. The four moving frames 18 are respectively located on the four inner sides of the top frame 13. Each moving frame 18 is located between one side of the plywood 55 and the top frame 13. Each second mounting plate 25 is slidably arranged on one side of a moving frame 18. Specifically, the second mounting plate 25 is located on the side of the moving frame 18 away from the top frame 13. Each moving component is located between a second mounting plate 25 and a moving frame 18. The moving component can realize the movement of the second mounting plate 25, so that the second mounting plate 25 can move along the length direction of the moving frame 18. Each grinding roller 26 is located at a The second mounting plate 25 is located at a side away from the moving frame 18. By arranging grinding rollers 26 on the four sides of the plywood 55, the four sides of the plywood 55 can be grinded simultaneously, that is, the equipment can grind the four sides of the plywood 55 simultaneously in one operation without grinding in batches, which not only reduces the equipment operation cost, but also greatly improves the grinding efficiency of the plywood 55 and meets the use requirements. Each driving component is located on one side of a grinding roller 26, and the driving component can drive the grinding roller 26 to rotate, so that the grinding roller 26 can grind the side of the plywood 55. Each rotating component is located above a moving frame 18, and each lifting component is located between the rotating component and a grinding roller 26. The lifting component enables the grinding roller 26 to perform reciprocating lifting and lowering motion, so that the grinding roller 26 can perform convenient grinding on the side of the plywood 55.

[0050] By setting a moving component, the grinding roller 26 can be driven to move along the side of the plywood 55. At the same time, under the action of the rotating component, the grinding roller 26 moves horizontally along the side of the plywood 55, and the lifting component can drive the grinding roller 26 to perform reciprocating lifting and lowering motions, that is, the grinding roller 26 can perform fine grinding on the side of the plywood 55 in a small range, and at the same time, it can move along the side of the plywood 55 to perform comprehensive grinding treatment on the side of the plywood 55. The grinding process is more delicate, so that the grinding treatment effect is better;

[0051] By setting a rotating component, a linkage effect can be achieved between the lifting component and the moving component, that is, a first motor 21 can realize longitudinal reciprocating lifting motion while the grinding roller 26 moves horizontally, without installing a driving source on each component, which greatly reduces the number of driving sources used in the device;

[0052] The adjusting mechanism comprises a mounting frame 15, a telescopic assembly and a transmission assembly. The mounting frame 15 is fixed above the top frame 13. The telescopic assembly is located between the mounting frame 15 and the four moving frames 18. When working, the telescopic assembly can drive the four moving frames 18 to move synchronously, so that the four moving frames 18 can synchronously approach or move away from the plywood 55. The transmission assembly is located between the telescopic assembly and one of the lifting assemblies. By utilizing the transmission assembly, the telescopic assembly can be driven to work by the transmission assembly while the lifting assembly is working, that is, while the plywood 55 moves upward, the four grinding rollers 26 can move toward the direction of the plywood 55 and contact the plywood 55. After grinding is completed, when the lifting assembly drives the plywood 55 to reset downward, the four grinding rollers 26 can move in the direction away from the plywood 55 to prepare for the grinding of the next plywood 55. That is, by utilizing the transmission assembly, a linkage effect can be achieved between the lifting assembly and the telescopic assembly, which is beneficial to reducing the number of driving sources used in the equipment, reducing power consumption, and thus helping to reduce costs.

[0053] like Figure 1-Figure 12 As shown, a plurality of fixed top rods 49 are fixed to the bottom end of the mounting frame 15, and a fixed top plate 48 is fixed to the bottom end of each fixed top rod 49. When the plywood 55 rises, the top end of the plywood 55 can contact the plurality of fixed top plates 48, and the fixed top plates 48 can be used to limit the position of the plywood 55. At the same time, a movable top plate 50 for supporting the plywood 55 is provided below the plywood 55. Therefore, the movable top plate 50 and the fixed top plate 48 can be used to position the plywood 55, thereby ensuring the stability of the plywood 55 during grinding.

[0054] Preferably, a non-slip pad for increasing friction may be provided on one side of the movable top plate 50 and the fixed top plate 48 close to the plywood 55 , thereby improving the fixing effect on the plywood 55 .

[0055] like Figure 1-Figure 12As shown, each moving assembly includes a first motor 21, a screw rod 22, an end plate 23 and a sliding seat 24. The end plate 23 is fixed to a side of the moving frame 18 away from the top frame 13. The sliding seat 24 is sleeved on the end plate 23 and slides inside the moving frame 18. The second mounting plate 25 is fixed to a side of the sliding seat 24 away from the moving frame 18. The screw rod 22 is rotatably arranged inside the moving frame 18. The sliding seat 24 and the screw rod 22 are threadedly matched. The first motor 21 is fixed to one end of the moving frame 18, and the output end of the first motor 21 is fixedly connected to one end of the screw rod 22.

[0056] During use, when the grinding roller 26 needs to be moved to one side of the plywood 55, the first motor 21 is controlled to work, and the first motor 21 can drive the screw rod 22 to rotate. Due to the threaded fit between the sliding seat 24 and the screw rod 22, and the sliding seat 24 slides inside the moving frame 18, when the screw rod 22 rotates, it can drive the sliding seat 24 to move inside the moving frame 18, thereby driving the second mounting plate 25 to move, so that the second mounting plate 25 can drive the grinding roller 26 on one side of the second mounting plate 25 to move horizontally along the side of the plywood 55.

[0057] like Figure 1-Figure 12 As shown, each lifting assembly includes a second turntable 30, a second hinge rod 31, a first mounting plate 59, two second guide rods 28 and two sliding blocks 29;

[0058] A U-shaped frame 27 is provided on one side of the grinding roller 26, and both ends of the grinding roller 26 are rotatably arranged inside the U-shaped frame 27. Specifically, a rotating shaft is provided in the middle of the grinding roller 26, and the rotating shaft is rotatably arranged on the U-shaped frame 27. The first mounting plate 59 is fixed on one side of the second mounting plate 25, and the second turntable 30 is rotatably arranged on one side of the first mounting plate 59. One end of the second hinged rod 31 is hinged to the surface edge of the first mounting plate 59, and the other end of the second hinged rod 31 is hinged to the middle part of the U-shaped frame 27. Two second guide rods 28 are symmetrically fixed on both sides of the second mounting plate 25, and each sliding block 29 is slidably arranged on a second guide rod 28, and each sliding block 29 is fixed on the U-shaped frame 27. The sliding connection between the U-shaped frame 27 and the second guide rod 28 can guide the U-shaped frame 27 when the U-shaped frame 27 is lifted or lowered.

[0059] When the moving component drives the second mounting plate 25 to move horizontally, the second turntable 30 can be driven to rotate under the action of the rotating component. When the second turntable 30 rotates, it can drive the U-shaped frame 27 to perform reciprocating lifting and lowering motion along the length direction of the second guide rod 28 through the second hinged rod 31, so that the grinding roller 26 can perform reciprocating lifting and lowering motion, thereby achieving small-scale fine grinding of the side of the plywood 55. At the same time, the grinding roller 26 can move horizontally along the plywood 55 to achieve comprehensive grinding of the side of the plywood 55.

[0060] like Figure 1-Figure 12 As shown, each rotating assembly includes a first bevel gear 32, a second bevel gear 33, a first spur gear 34 and a first rack 35;

[0061] The first bevel gear 32 is located on the side of the first mounting plate 59 away from the second rotating disk 30. The first bevel gear 32 is coaxial with the second rotating disk 30 and is fixedly connected, that is, when the first bevel gear 32 rotates, the second rotating disk 30 can be driven to rotate synchronously. The second bevel gear 33 is rotatably arranged on the second mounting plate 25, and the second bevel gear 33 is meshed with the first bevel gear 32. When the second bevel gear 33 rotates, the first bevel gear 32 can be driven to rotate. It should be noted here that the diameter of the second bevel gear 33 is larger than the diameter of the first bevel gear 32, which has the effect of speed increase. The first spur gear 34 is located on the side of the second mounting plate 25 away from the second bevel gear 33. The first spur gear 34 is coaxial with the second bevel gear 33 and is fixedly connected, that is, when the first spur gear 34 rotates, the second bevel gear 33 can be driven to rotate synchronously. The first rack 35 is fixedly mounted on the top of the moving frame 18 and is located below the first spur gear 34. The first spur gear 34 is meshed with the first rack 35.

[0062] When the screw rod 22 rotates and drives the second mounting plate 25 to move horizontally, the second mounting plate 25 can drive the first spur gear 34 to move. At this time, the first spur gear 34 can rotate while moving under the action of the first rack 35, so that the first spur gear 34 drives the second bevel gear 33 to rotate synchronously. The second bevel gear 33 and the first bevel gear 32 are meshed with each other. Therefore, when the second bevel gear 33 rotates, it drives the first bevel gear 32 to rotate. Therefore, when the first bevel gear 32 rotates, the second turntable 30 can be rotated, and the subsequent reciprocating lifting motion of the grinding roller 26 can be realized.

[0063] like Figure 1-Figure 12 As shown, each driving assembly includes a side plate 58, a second motor 36, a driving wheel 37, a driven wheel 38 and a transmission belt 39. The side plate 58 is fixed to one side of the U-shaped frame 27 and is slidably arranged on the second mounting plate 25. Specifically, the side plate 58 is fixedly connected to the U-shaped frame 27. When the U-shaped frame 27 is lifted or lowered, the side plate 58 can be driven to lift or lower. At the same time, a slider is provided at one end of the side plate 58 away from the U-shaped frame 27. A slide groove is provided on the surface of the second mounting plate 25. The slider is slidably arranged inside the slide groove. The rotating shaft of the grinding roller 26 passes through the U-shaped frame 27 and the side plate 58 and is fixedly connected to the driven wheel 38. When the second motor 36 rotates, the grinding roller 26 can be driven to rotate in the middle of the U-shaped frame 27. The second motor 36 is fixed to the side plate 58. The output end of the second motor 36 is fixedly connected to the driving wheel 37. The transmission belt 39 is sleeved on the driving wheel 37 and the driven wheel 38.

[0064] When it is necessary to grind the side of the plywood 55 , the second motor 36 is controlled to work, and the second motor 36 can drive the driving wheel 37 to rotate, and under the action of the transmission belt 39, the driven wheel 38 can be driven to rotate, so that the grinding roller 26 can rotate, which is convenient for the grinding roller 26 to grind the side of the plywood 55 .

[0065] like Figure 1-Figure 12 As shown, the telescopic assembly includes a first rotating disk 16 and four first hinged rods 17. The first rotating disk 16 is rotatably arranged at the bottom end of the mounting frame 15. One end of each first hinged rod 17 is hinged to the surface edge of the first rotating disk 16, and the other end of each first hinged rod 17 is hinged to the middle of the top end of a moving frame 18.

[0066] Two first guide rods 19 are symmetrically fixed to one side of each moving frame 18 close to the top frame 13. A first through hole 20 matching with the first guide rod 19 is opened on the surface of the top frame 13. Each first guide rod 19 is slidably arranged inside a first through hole 20.

[0067] When the jacking assembly is working, the first turntable 16 can be driven to rotate through the transmission assembly. When the first turntable 16 rotates, the moving frame 18 can be driven by the first hinged rod 17 to slide inside the first perforation 20, thereby realizing the extension and retraction of the moving frame 18, so that the four moving frames 18 can all move toward the side close to the plywood 55, and then the four grinding rollers 26 on the four moving frames 18 can be moved to the four sides of the plywood 55 and contact with the plywood 55, so as to facilitate the subsequent grinding of the side edges of the plywood 55.

[0069] When in use, when the side of the plywood 55 needs to be processed, the electric push rod 53 is controlled to work, and the electric push rod 53 can lift the movable plate 52 upward, so that the movable top plate 50 can be driven to move through the multiple movable top rods 51, so that the plywood 55 above the multiple movable top plates 50 can be lifted, so that the plywood 55 can be away from the driving roller on the roller conveyor 12;

[0070] Preferably, in actual use, a position sensor can be provided on one side of the roller conveyor 12, and the position sensor is electrically connected to the controller. When the position sensor detects that the plywood 55 moves to a preset position, a signal is sent to the controller, and the controller controls the roller conveyor 12 to stop working, that is, to stop conveying the plywood 55, so that the plywood 55 can be lifted up for grinding as needed.

[0071] like Figure 1-Figure 12 As shown, the transmission assembly includes a second spur gear 40, a second rack 41, a first guide rail 42, a vertical plate 43, a third guide rod 44, a second through hole 45, a spring 46, a pull rope 47, a strip groove 56, a connecting rod 57 and a guide wheel 60;

[0072] The second spur gear 40 is located at the top of the mounting frame 15 and is coaxially fixedly connected with the first rotating disk 16, that is, when the second spur gear 40 rotates, it can drive the first rotating disk 16 to rotate synchronously. The first guide rail 42 is fixed on the top of the mounting frame 15. The second rack 41 is slidably arranged inside the first guide rail 42. The first guide rail 42 is used to guide the second rack 41. The second rack 41 and the second spur gear 40 are meshed with each other. The vertical plate 43 is located at one end of the first guide rail 42 and is fixed to the top of the mounting frame 15. The second through hole 45 is opened on the vertical plate 43. The third guide rod 44 is slidably arranged inside the second through hole 45, and one end of the third guide rod 44 is fixedly connected to the end of the second rack 41. The spring 46 is sleeved on the third guide rod 44, and the two ends of the spring 46 are respectively fixedly connected to the second rack 41 and the vertical plate 43;

[0073] The strip groove 56 is provided on the side wall of the roller conveyor 12, the connecting rod 57 is slidably arranged inside the strip groove 56, and one end of the connecting rod 57 is fixedly connected to one of the movable plates 52, the guide wheel 60 is installed on the mounting frame 15, specifically, the guide wheel 60 rotates on the mounting frame 15, one end of the pull rope 47 is fixedly connected to one end of the second rack 41 away from the third guide rod 44, the other end of the pull rope 47 passes around the guide wheel 60 and is fixedly connected to the connecting rod 57, and the first turntable 16 can guide the pull rope 47;

[0074] In the initial state, the spring 46 is in a stretched state, and the plywood 55 is located on the roller conveyor 12. When the electric push rod 53 is working to lift the plywood 55, the moving plate 52 drives the connecting rod 57 to slide inside the strip groove 56. At this time, under the action of the spring 46, the second rack 41 can be driven to move toward the side close to the vertical plate 43. When moving, the second rack 41 can drive the second spur gear 40 to rotate a certain angle, thereby driving the first turntable 16 to rotate, thereby driving the four moving frames 18 to move toward the side close to the plywood 55, that is, when the plywood 55 is lifted, the four grinding rollers 26 can move toward the direction of the plywood 55 and contact the plywood 55;

[0075] When the grinding is finished, the vertical plate 43 drives the moving plate 52 to move downward, and the plywood 55 moves downward with the moving plate 52 under the action of gravity. When the moving plate 52 moves, it drives the connecting rod 57 to move downward inside the strip groove 56. At this time, under the action of the pull rope 47, the second rack 41 can be driven to move in the direction away from the vertical plate 43, thereby driving the second spur gear 40 to move in the opposite direction, so that the first rotating disk 16 can move in the opposite direction, so that the four moving frames 18 can move to the side away from the plywood 55, that is, when the plywood 55 moves downward to reset, the four grinding rollers 26 can move in the direction away from the plywood 55 to prepare for the grinding of the next plywood 55;

[0076] That is, by utilizing the transmission component, a linkage effect can be achieved between the jacking component and the telescopic component, which is beneficial to reducing the number of driving sources used in the device, reducing power consumption, and further helping to reduce costs.

[0077] like Figure 1-Figure 12 As shown, a plurality of vertical rods 14 are symmetrically fixed to the outside of the top frame 13 , each of the vertical rods 14 is located outside the roller conveyor 12 and fixed to the top of the bottom plate 11 , and the top frame 13 can be supported and installed by the vertical rods 14 .

[0078] The specific working process of the present invention is as follows:

[0079] First, the plywood 55 to be processed is placed on the roller conveyor 12, and the roller conveyor 12 is used to convey the plywood 55. When the plywood 55 is conveyed to the preset position, the controller controls the roller conveyor 12 to stop working, and then controls the electric push rod 53 to work. The electric push rod 53 can lift the movable plate 52 upward, so that the movable top plate 50 can be driven to move by the multiple movable top rods 51, so that the plywood 55 above the multiple movable top plates 50 can be lifted, so that the plywood 55 can be away from the driving rollers on the roller conveyor 12. At the same time, when the plywood 55 rises, the top of the plywood 55 can contact with the multiple fixed top plates 48, and the fixed top plates 48 can be used to limit the plywood 55. At the same time, a movable top plate 50 for supporting the plywood 55 is arranged below the plywood 55, so the positioning of the plywood 55 can be achieved by using the movable top plate 50 and the fixed top plate 48;

[0080] At the same time, when the electric push rod 53 is working to lift the plywood 55, the moving plate 52 drives the connecting rod 57 to slide inside the strip groove 56. At this time, the second rack 41 can be driven to move toward the side close to the vertical plate 43 under the action of the spring 46. When moving, the second rack 41 can drive the second spur gear 40 to rotate a certain angle, thereby driving the first rotating disk 16 to rotate, thereby driving the four moving frames 18 to move toward the side close to the plywood 55. That is, when the plywood 55 is lifted, the four grinding rollers 26 can move toward the direction of the plywood 55 and contact the plywood 55.

[0081] Then, the second motor 36 is controlled to work. When the second motor 36 is working, it can drive the driving wheel 37 to rotate, and under the action of the transmission belt 39, it can drive the driven wheel 38 to rotate, thereby driving the grinding roller 26 to rotate inside the U-shaped frame 27;

[0082] At the same time, the first motor 21 is controlled to work, and the first motor 21 can drive the screw rod 22 to rotate. Since the sliding seat 24 and the screw rod 22 are threadedly matched, and the sliding seat 24 slides inside the moving frame 18, when the screw rod 22 rotates, it can drive the sliding seat 24 to move inside the moving frame 18, thereby driving the second mounting plate 25 to move, so that the second mounting plate 25 can drive the grinding roller 26 on one side of the second mounting plate 25 to move horizontally along the side of the plywood 55. When the screw rod 22 rotates and drives the second mounting plate 25 to move horizontally, the second mounting plate 25 can drive the first spur gear 34 to move. At this time, the first spur gear 34 can be driven by the first rack 35 to move horizontally. The first bevel gear 33 is rotated while moving, so that the first spur gear 34 drives the second bevel gear 33 to rotate synchronously, and the second bevel gear 33 and the first bevel gear 32 are meshed with each other, so when the second bevel gear 33 rotates, it drives the first bevel gear 32 to rotate, so that when the first bevel gear 32 rotates, the second turntable 30 can be rotated, and when the second turntable 30 rotates, it can drive the U-shaped frame 27 to perform reciprocating lifting and lowering motion along the length direction of the second guide rod 28 through the second hinge rod 31, so that the grinding roller 26 can perform reciprocating lifting and lowering motion, so as to achieve fine grinding of the side of the plywood 55 with a small amplitude, and at the same time, the grinding roller 26 can move horizontally along the plywood 55 to achieve comprehensive grinding of the side of the plywood 55;

[0083] After the grinding is completed, the vertical plate 43 drives the movable plate 52 to move downward, and the plywood 55 moves downward with the movable plate 52 under the action of gravity. When moving, the movable plate 52 drives the connecting rod 57 to move downward inside the strip groove 56. At this time, under the action of the pull rope 47, the second rack 41 can be driven to move in the direction away from the vertical plate 43, thereby driving the second spur gear 40 to move in the opposite direction, so that the first turntable 16 can move in the opposite direction, so that the four movable frames 18 can move toward the side away from the plywood 55, that is, when the plywood 55 moves downward to reset, the four grinding rollers 26 can move in the direction away from the plywood 55 to prepare for the grinding of the next plywood 55.

[0084] The beneficial effects of the present invention are specifically embodied in that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
