Description

Technical Field

[0001] The invention relates to the technical field of wood polishing, in particular to dust-proof polishing equipment and application thereof in carbonized wood processing. Background Art

[0002] Carbonized wood processing is a process for treating wood, which can effectively improve the stability, durability and many other properties of wood.

[0003] Carbonized wood processing mainly uses high temperature to treat wood. In an oxygen-free or low-oxygen environment, the wood is heated to a certain temperature. In this process, the hemicellulose inside the wood will decompose and produce organic acids such as acetic acid, which can inhibit some microorganisms in the wood (such as fungi, insects, etc.). At the same time, the cellulose and other components in the wood will undergo some physical and chemical changes, making the structure of the wood more compact, thereby improving the strength and stability of the wood.

[0004] After the carbonization of the carbonized wood is completed, the carbonized wood is usually cut into the required sheet-shaped plates and then the surface of the wood is polished. The existing polishing process is to use polishing equipment to first perform rough polishing on the wood and then perform fine polishing. However, when adjusting the polishing accuracy, it is usually necessary to replace the required polishing roller after stopping the machine, which undoubtedly increases the polishing steps and costs, resulting in a problem of reduced polishing efficiency. If the carbonized wood is polished through a double station, the floor space required for the equipment increases, and the dust-raising space inside it increases accordingly, resulting in a reduced dust removal effect. Summary of the invention

[0016] It also includes a gear fixedly mounted on the rotating rod and meshing with the rack plate, and a sliding structure connected to the rack plate is provided on the support plate.

[0017] As a further solution of the present invention: the sliding structure includes a second sliding groove provided on the support plate, a second sliding block is slidably installed in the second sliding groove, and a second connecting rod hinged to the rack plate is hinged on the second sliding block.

[0018] As a further solution of the present invention: the guide assembly includes a first slide groove which is symmetrically arranged on the movable plate, a first sliding block is slidably installed in the first slide groove, and a first connecting rod which is hinged to the second sliding block is hinged on the first sliding block;

[0019] It also includes a limiting column fixedly mounted on the first sliding block, and a guide groove is opened on the inner wall of the machine platform, and the guide groove is slidably engaged with the limiting column.

[0020] As a further solution of the present invention: the guide groove includes a first straight groove, a first oblique groove, a second straight groove, and a second oblique groove, and the first straight groove, the first oblique groove, the second straight groove, and the second oblique groove are connected to each other from beginning to end.

[0021] As a further solution of the present invention: the follow-up dust suction component includes a conduit connected to the machine and rotatably connected to the rotating rod, the conduit is connected to a symmetrically arranged diversion pipe, the rotating rod is provided with a conducting hole that is conductive and cooperates with the diversion pipe, and the support plate is provided with a negative pressure component connected to the diversion pipe.

[0022] As a further solution of the present invention: the negative pressure assembly includes a fixing plate fixedly mounted on the supporting plate, a dust suction nozzle is fixed on the fixing plate, and the dust suction nozzle is connected to the shunt pipe.

[0023] The invention discloses an application of dust-proof polishing equipment in carbonized wood processing, and adopts the dust-proof polishing equipment.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: the present application can realize the exchange of the positions of the first polishing roller and the second polishing roller through the cooperation of the guide component and the polishing switching mechanism, so as to perform rough polishing and fine polishing treatment on the wood. Specifically, when the conveyor belt transports the wood to the position cooperating with the first polishing roller, under the action of the translation component, the first polishing roller is controlled to move along the length direction of the wood. At the same time, under the action of the polishing switching mechanism, the first polishing roller is controlled to rotate to perform rough polishing treatment on the wood. Under the action of the follow-up dust suction component, the wood chips generated during polishing can be absorbed and treated. In order to prevent the problem of wood chips flying and causing damage to parts in the machine, after the rough polishing is completed, under the action of the guide assembly and the polishing switching mechanism, the positions of the first polishing roller and the second polishing roller are swapped, so that the wood can be finely polished by the second polishing roller. By adjusting the positions of the first polishing roller and the second polishing roller, the wood can be roughly polished when the movable plate reciprocates once, so that the uneven parts of the wood surface can be quickly ground off through strong cutting ability to make the wood initially flat, and then fine polishing is performed to further refine the wood surface and make the wood surface smoother.

[0025] By switching between the first polishing roller and the second polishing roller, the overall integration of the equipment is higher, the volume is smaller, and the space occupied is smaller. Similarly, the reduced volume of the equipment means that the dust-raising space inside it is smaller, and the dust collection and dust removal effect of impurities such as sawdust generated during polishing is better.

[0026] Through the cooperation of the guide assembly and the polishing switching mechanism, the positions of the first polishing roller and the second polishing roller can be quickly switched after the rough polishing is completed, avoiding the need to stop the machine for replacement, thereby increasing the efficiency of the wood polishing process. In the switching process, since the rotating rod only needs to rotate half a circle to achieve switching, the rack plate and the gear have the advantage of high transmission accuracy, which can ensure that the first polishing roller and the second polishing roller move accurately to the required position, and can also avoid the rotational inertia caused by the use of a driving source such as a motor, which causes the first polishing roller and the second polishing roller to offset when switching their positions. At the same time, since the rough and fine polishing share the same reference, the processing is consistent in terms of isotopeness, achieving a higher precision effect on wood polishing.

[0027] By adjusting the connection state of the two dust suction nozzles and the duct, it can be achieved that there is always a dust suction nozzle to absorb the debris in the forward direction of the first polishing roller and the second polishing roller. This can not only absorb the debris generated by polishing, but also ensure the suction generated by the duct. The gas will not be diverted due to the connection of the two dust suction nozzles, resulting in a decrease in the suction force and failure to fully absorb the debris.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0041] See also Figures 1 to 10 In an embodiment of the present invention, a dust-proof polishing device includes:

[0042] A machine 1, and a receiving plate 2 fixedly mounted on the machine 1, a conveying assembly is arranged on the receiving plate 2, and the conveying assembly includes a belt wheel rotatably mounted on the receiving plate 2 and symmetrically arranged, a conveying belt 3 is sleeved on the belt wheel, and a plurality of limit blocks 301 distributed at equal distances are fixed on the conveying belt 3;

[0043] Also includes:

[0044] A translation assembly is arranged in the machine platform 1, the translation assembly is connected to a movable plate 6, and a symmetrically arranged support plate 11 is fixed to the movable plate 6;

[0045] A polishing switching mechanism is arranged on the support plate 11, the polishing switching mechanism is connected to a first polishing roller 22 and a second polishing roller 23, the movable plate 6 is provided with a guide assembly connected to the polishing switching mechanism, and the guide assembly can adjust the height of the first polishing roller 22 and the second polishing roller 23 through the polishing switching mechanism when the movable plate 6 moves;

[0046] The follow-up dust suction mechanism is arranged in the machine 1 and connected to the polishing switching mechanism, and is used for absorbing the debris generated by polishing.

[0047] Specifically, the first polishing roller 22 and the second polishing roller 23 are used for rough polishing and fine polishing respectively, and the limit block 301 is used to limit the carbonized wood. When polishing the carbonized wood, the wood can be placed on the conveyor belt 3. Under the action of the limit block 301, the four corners of the wood are limited so that the wood will not be relatively displaced on the conveyor belt 3, thereby ensuring that the wood will not move during polishing. Under the action of the conveyor belt 3, the wood is translated to a position coordinated with the first polishing roller 22 and the second polishing roller 23. At this time, the first polishing roller 22 can be controlled to rotate by the polishing switching mechanism, and the movable plate 6 can be controlled to move along the length direction of the wood by the translation assembly, so that the surface of the wood is roughly polished by the first polishing roller 22. Under the action of the follow-up dust collection mechanism , absorb the debris generated by polishing to prevent wood chips from flying in the machine 1 and causing damage to the internal parts of the machine 1 and affecting the subsequent fine polishing efficiency. When the first polishing roller 22 is separated from the wood, under the action of the guide component, the polishing switching mechanism is controlled to move to adjust the position between the first polishing roller 22 and the second polishing roller 23. The second polishing roller 23 will move to a position that cooperates with the wood. At this time, the translation component controls the movable plate 6 to move toward the initial position to perform fine polishing on the wood surface through the second polishing roller 23. When the polishing is completed, the conveyor belt 3 can control the wood to leave the machine 1 and repeat the above steps, thereby achieving the mutual cooperation of rough polishing and fine polishing, and absorbing the debris during the polishing process to ensure that the wood achieves the best polishing effect.

[0048] See also Figure 2 , Figure 4 , Figure 5The translation assembly includes a screw rod 4 rotatably installed in the machine platform 1, a threaded sleeve 5 is threadedly connected to the screw rod 4, a guide column 7 is fixed in the machine platform 1, a guide sleeve 8 is slidably installed on the guide column 7, and the guide sleeve 8 and the threaded sleeve 5 are fixedly connected to the movable plate 6 respectively.

[0049] In detail, when polishing carbonized wood, the carbonized wood can be placed on the conveyor belt 3, and under the action of the conveyor belt 3, the wood enters the machine 1 and moves to the position cooperating with the first polishing roller 22 and the second polishing roller 23. At this time, the screw 4 rotates and drives the threaded sleeve 5 to move, thereby driving the movable plate 6 to move. The movable plate 6 will control the guide sleeve 8 to move along the length direction of the guide column 7. Since the guide sleeve 8 and the guide column 7 have a guiding function, it can be ensured that the threaded sleeve 5 moves along the length direction of the screw 4 and will not rotate with the screw 4. The movable plate 6 will also drive the polishing switching mechanism to move through the support plate 11 to control the first polishing roller 22 and the second polishing roller 23 to move along the length direction of the wood. The first polishing roller 22 will perform a rough polishing action on the surface of the wood, wherein the screw 4 can be driven by a motor. This is an application of the prior art and will not be elaborated in this application.

[0050] See also Figure 1 , Figure 2 , Figure 4-Figure 10 , the polishing switching mechanism includes a rotating rod 12 rotatably mounted on the support plate 11, a rotating plate 19 is fixed at the end of the rotating rod 12, a symmetrically arranged motor 21 is fixed on the rotating plate 19, and the output shafts of the two motors 21 are respectively connected to the rotating shafts of the first polishing roller 22 and the second polishing roller 23, and a toothing assembly is provided on the support plate 11, wherein the toothing assembly includes a third slide groove 1102 opened on the support plate 11, a third sliding block 17 is slidably mounted in the third slide groove 1102, and a rack plate 18 is fixed on the third sliding block 17; it also includes a gear 13 fixedly mounted on the rotating rod 12 and meshing with the rack plate 18, and a sliding structure connected to the rack plate 18 is provided on the support plate 11, and the above-mentioned sliding structure includes a second slide groove 1101 opened on the support plate 11, a second sliding block 15 is slidably mounted in the second slide groove 1101, and a second connecting rod 16 hinged to the rack plate 18 is hinged on the second sliding block 15.

[0051] It should be noted that two motors 21 are provided, which are used to control the rotation of the first polishing roller 22 and the second polishing roller 23 respectively. In the initial state, under the action of the guide component, the second sliding block 15 is located at the end of the stroke in the second slide groove 1101 close to the movable plate 6. Under the action of the second connecting rod 16, the third sliding block 17 is controlled by the rack plate 18 to be located at the end of the stroke on one side of the third slide groove 1102. Since the guide component has a locking effect, it can be ensured that the position of the rack plate 18 will not change at this time. Under the action of the rack plate 18 and the gear 13, it is ensured that the rotating rod 12 is in a fixed state, so as to lock the positions of the first polishing roller 22 and the second polishing roller 23 through the rotating plate 19. At this time, the motor 21 connected to the first polishing roller 22 rotates, and drives the first polishing roller 22 to rotate, so as to perform a rough polishing treatment on the wood surface. At the same time, the screw 4 rotates to control the first polishing roller 22 to move along the length direction of the guide column 7, so as to ensure that the wood surface is comprehensively rough polished. When the rough polishing is completed, the first polishing roller 22 will be separated from the wood surface. At this time, under the action of the guide component, the second sliding The block 15 moves along the length direction of the second slide groove 1101 and moves in the direction away from the movable plate 6. The second sliding block 15 will control the rack plate 18 and the third sliding block 17 to move along the length direction of the third slide groove 1102 through the second connecting rod 16. Since the rack plate 18 and the gear 13 are meshed with each other, the gear 13 will rotate to control the rotation of the rotating plate 19 through the rotating rod 12. The rotating plate 19 will drive the first polishing roller 22 and the second polishing roller 23 to move. When the rack plate 18 moves to the end of the stroke, the rotating rod 12 just rotates half a circle. The positions of the first polishing roller 22 and the second polishing roller 23 are switched so that the second polishing roller 23 moves to a position cooperating with the wood. Under the action of the guide assembly, the position of the second sliding block 15 is locked again to ensure that the positions of the first polishing roller 22 and the second polishing roller 23 will not shift during the polishing process. A support sleeve 20 is fixed on the support plate 11 and is sleeved on the rotating rod 12. Under the action of the support sleeve 20, the stability of the rotating rod 12 can be increased to ensure that the rotating rod 12 will not bend due to the reaction force generated during polishing.

[0052] Preferably, in order to further enhance the polishing effect, after the positions of the first polishing roller 22 and the second polishing roller 23 are swapped, the screw 4 is reversed to control the movable plate 6 to move toward the initial position, so that the second polishing roller 23 can be used to fine-polish the wood surface. When the fine polishing is completed, under the action of the guide assembly, the second sliding block 15 returns to the end of the stroke of the second slide groove 1101 toward the side of the movable plate 6, so that the positions of the first polishing roller 22 and the second polishing roller 23 are swapped again. By adjusting the positions of the first polishing roller 22 and the second polishing roller 23, it is possible to achieve a rough polishing treatment on the wood when the movable plate 6 reciprocates once, so that the uneven parts of the wood surface can be quickly ground off through a strong cutting ability to make the wood initially flat, and then fine polishing is performed to further refine the wood surface and make the wood surface smoother.

[0053] Among them, through the cooperation of the guiding assembly and the polishing switching mechanism, the positions of the first polishing roller 22 and the second polishing roller 23 can be quickly switched after the rough polishing is completed, avoiding the problem of stopping the machine for replacement, thereby increasing the efficiency of the wood polishing process. In addition, during the switching process, since the rotating rod 12 only needs to rotate half a circle to achieve switching, the rack plate 18 and the gear 13 have the advantage of high transmission accuracy, which can ensure that the first polishing roller 22 and the second polishing roller 23 can be accurately moved to the required position, and can also avoid the rotational inertia caused by the use of a driving source such as a motor, which causes the first polishing roller 22 and the second polishing roller 23 to be offset when the position is switched.

[0054] See also Figure 2-Figure 5 , Figure 7 , Figure 8 The guide assembly includes a first slide groove 601 which is opened on the movable plate 6 and is symmetrically arranged, a first sliding block 9 is slidably installed in the first slide groove 601, and a first connecting rod 14 which is hinged to the second sliding block 15 is hinged on the first sliding block 9; it also includes a limiting column 10 fixedly installed on the first sliding block 9, and a guide groove is opened on the inner wall of the machine 1, and the guide groove is slidably engaged with the limiting column 10, wherein the guide groove includes a first straight groove 101, a first oblique groove 102, a second straight groove 103, and a second oblique groove 104, and the first straight groove 101, the first oblique groove 102, the second straight groove 103, and the second oblique groove 104 are connected to each other in sequence from head to tail.

[0055] Further, in the initial state, the limit column 10 is located at the connection position of the first straight groove 101 and the second inclined groove 104, so that the first sliding block 9 is located at the end of the stroke on one side of the first sliding groove 601, and the distance between the two first sliding blocks 9 is the smallest. Under the action of the first sliding block 9, the second sliding block 15 is controlled by the first connecting rod 14 to be located at the end of the stroke on one side of the second sliding groove 1101 close to the movable plate 6. At this time, the first polishing roller 22 is located at the position matching the wood. When the wood needs to be polished, the screw rod 4 rotates to make the movable plate 6 move along the length direction of the guide column 7. The plate 6 will also drive the limiting column 10 to move along the length direction of the first straight groove 101 through the first sliding block 9. Under the action of the limiting column 10 and the first straight groove 101, the position of the first sliding block 9 is locked to ensure that the position of the first polishing roller 22 will not change. When the rough polishing is completed, since the movable plate 6 continues to move along the length direction of the guide column 7, the limiting column 10 will be separated from the first straight groove 101 and enter the first inclined groove 102, so that the two first sliding blocks 9 move in a direction away from each other, so as to control the second sliding block 15 to move away from the movable plate through the first connecting rod 14. 6, under the action of the rack plate 18 and the gear 13, the rotating rod 12 is controlled to rotate to adjust the positions of the first polishing roller 22 and the second polishing roller 23. When the limiting column 10 moves to the connecting position of the first inclined groove 102 and the second straight groove 103, the positions of the first polishing roller 22 and the second polishing roller 23 are interchanged to perform fine polishing on the wood by the second polishing roller 23. At this time, the screw rod 4 is reversed to control the movable plate 6 to move toward the initial position, and the limiting column 10 will slide along the second straight groove 103. When the fine polishing is completed, the movable plate 6 continues to move along the length of the guide column 7. When the first polishing roller 22 and the second polishing roller 23 move in the opposite direction, the limiting column 10 will disengage from the second straight groove 103 and enter the second inclined groove 104, so that the first sliding block 9 moves toward the initial position to reverse the rotating rod 12. When the limiting column 10 returns to the position where the second straight groove 103 is connected to the first straight groove 101, the first polishing roller 22 and the second polishing roller 23 return to the initial position. Through the cooperation between the guide groove and the limiting column 10, the position of the first polishing roller 22 and the second polishing roller 23 can be controlled to be exchanged after the rough polishing or the fine polishing is completed. The angle of the rotating rod 12 can also be locked during the polishing process to ensure the best polishing accuracy.

[0056] See also Figure 2 , Figure 4 , Figure 5 , Figure 7 , Fig. 9 , Fig.10The follow-up dust collection component includes a conduit 26 connected to the machine 1 and rotatably connected to the rotating rod 12, the conduit 26 is connected to a symmetrically arranged shunt pipe 27, the rotating rod 12 is provided with a conducting hole 1201 that is conductively connected to the shunt pipe 27, and the support plate 11 is provided with a negative pressure component connected to the shunt pipe 27, wherein the negative pressure component includes a fixed plate 24 fixedly mounted on the support plate 11, and a dust collection nozzle 25 is fixed on the fixed plate 24, and the dust collection nozzle 25 is connected to the shunt pipe 27.

[0057] Furthermore, the duct 26 is connected to the fan to form a negative pressure in the dust nozzle 25. When polishing the wood, debris will be generated. In order to prevent the debris from splashing and causing damage to the parts in the machine 1, the debris needs to be absorbed. When absorbing, it is necessary to ensure that the dust nozzle 25 is located in front of the debris splashing direction. There are two groups of shunt pipes 27 and dust nozzles 25, which are respectively located on both sides of the first polishing roller 22. In the initial state, the conducting hole 1201 is connected to one of the shunt pipes 27, so that one of the dust nozzles 25 located in the forward direction of the first polishing roller 22 is connected to the duct 26, and the other shunt pipe 27 is in a blocked state. When the first polishing roller 22 is moved forward, the dust nozzle 25 is blocked. When the smooth roller 22 is polishing the wood, the fan is working and forms a negative pressure in the dust nozzle 25 through the duct 26 and the diverter pipe 27. Under the action of the negative pressure, the debris generated during the polishing process is absorbed. When the rough polishing is completed, under the action of the guide assembly and the polishing switching mechanism, the rotating rod 12 is rotated to interchange the positions of the first polishing roller 22 and the second polishing roller 23. When the rotating rod 12 rotates, it also drives the guide hole 1201 to move, so that the other dust nozzle 25 is connected to the duct 26. This dust nozzle 25 is located in the forward direction of the second polishing roller 23, so that during fine polishing, the debris is absorbed by the dust nozzle 25.

[0058] Preferably, by adjusting the connection state of the two dust nozzles 25 and the duct 26, it can be achieved that in the forward direction of the first polishing roller 22 and the second polishing roller 23, there is always a dust nozzle 25 to absorb the debris, which can not only absorb the debris generated by polishing, but also ensure the suction force generated by the duct 26. The gas will not be diverted due to the connection of the two dust nozzles 25, resulting in a decrease in the suction force and the inability to fully absorb the debris.
