Description

Technical Field

[0001] The invention relates to the technical field of veneer processing, and in particular to a dust removal and separation device for veneer processing. Background Art

[0002] Veneer is a material made by cutting logs into thin sheets. It has the advantages of natural beauty, resource efficiency, and diverse selection. It is widely used in furniture manufacturing, interior decoration, construction and other fields. Veneer can not only provide the beautiful appearance of natural wood, but also effectively utilize wood resources and reduce the demand for whole pieces of wood.

[0003] Veneer processing dust removal involves the use of efficient dust removal equipment and technical means, such as bag filters, to remove sawdust dust generated during processing. These devices significantly reduce dust concentration in the air through filtering and separation technology, improve the working environment, reduce pollution to the atmosphere, and ensure processing quality and production efficiency.

[0004] For example, a Chinese patent with publication number CN218854934U discloses a dust removal machine for veneer processing, including a frame, a dust collection component is arranged in the middle position of the frame, the dust collection component includes a box body, a protective cover A, a protective cover B, a pipeline, a vacuum pump, and a collection box, the dust removal component is arranged inside the box body, feeding components are arranged on both sides of the box body, and a control component is arranged on the outer wall of the box body; by providing a vacuum pump, the vacuum pump generates a negative pressure environment in the pipeline, and the dust is collected in time, and a collection box is provided, and the collection box collects the dust for the next step of processing to prevent the dust from causing secondary pollution to the veneer; by providing a motor A, the motor A drives the brush A to rotate, and with the cooperation of the brush B, the dust is removed from the surface of the veneer, thereby ensuring the dust removal efficiency.

[0005] However, the above device still has some shortcomings in actual use:

[0006] 1. The feeding assembly of the above device sends the veneer into the box, and then uses the vacuum pump in the box to remove dust. However, only one side of the veneer sent into the box can be dusted and adsorbed, and the other side of the veneer needs to be dusted again using the same method. This will make the process more complicated and will also cause the veneer on one side that has been cleaned after the veneer is sent into the box to be re-stained with dust, affecting the dust removal effect.

[0007] 2. The above device uses a brush to sweep away the dust adhering to the wooden board. However, since the brush is composed of many independent bristles, dust is easy to hide in the gaps between the bristles and is difficult to completely remove. Over time, the dust removal efficiency of the brush will gradually weaken, thereby causing secondary pollution to the veneer.

[0008] Therefore, based on the above viewpoints, it is very important to improve and perfect the dust removal machine used for veneer processing, which not only solves the problem of only being able to clean one side of the veneer at a time, but also effectively avoids the accumulation of dust on the brush.

DETAILED DESCRIPTION

[0040] The following is combined with Figure 1-Figure 10 Embodiments of the present invention are described in detail.

[0041] The embodiment of the present application discloses a dust removal and separation device for veneer processing, which explains that the present invention is mainly used in the process of veneer processing, and can technically avoid the problem that only one side of the veneer can be subjected to dust adsorption, resulting in cumbersome procedures and affecting the dust removal effect; further, the present invention can also solve the problem that dust accumulates on the existing brush, causing secondary pollution to the veneer being dusted, resulting in reduced dust removal effect of the brush.

[0042] Embodiment 1:

[0043] Reference Figure 1 and Figure 2 As shown, it comprises a processing box 1, inside of which veneer 10 is wound. The veneer 10 in the present invention is mainly veneer 10 with a thickness between 0.1 mm and 0.5 mm, which is easier to roll up.

[0044] A feeding port for the veneer 10 is provided on one side of the processing box 1. Three conveying rollers 11 are provided inside the processing box 1. The veneer 10 is wound on the conveying roller 11 in a U shape. A conveying roller 2 12 is also provided inside the processing box 1. The veneer 10 passes through the conveying roller 11 and then winds on the conveying roller 2 12 in an L shape. A winding roller 13 is also rotatably installed inside the processing box 1. One end of the veneer 10 passes through the conveying roller 11 and the conveying roller 2 12 and then winds on the winding roller 13. The remaining veneer 10 is moved along the route of the guide rail 30 by the rotation of the winding roller 13.

[0045] The veneer 10 entering the processing box 1 is rolled up and collected by the winding roller 13. During the rolling process, the front and back sides of the veneer 10 passing through the conveying roller 11 and the conveying roller 2 12 will face the direction of the winding roller 13. At this time, the dust on the front and back sides of the veneer 10 is adsorbed and processed inside the processing box 1, which can effectively process the dust on the front and back sides of the veneer 10, and prevent the dust on only one side of the veneer 10 from being adsorbed and collected, while the other side of the veneer 10 needs to be processed again through the same steps, which causes the veneer 10 that has been cleaned to be contaminated during the re-entry process.

[0046] A filter mechanism 2 for collecting and filtering dust is also provided inside the processing box 1. The adsorbed air mixed with dust will be filtered through the filter mechanism 2, and the filtered gas will return to the processing box 1 again to prevent dust in the air from falling onto the veneer 10, thereby affecting the dust removal effect of the veneer 10.

[0047] Reference Figure 3 , Figure 4 and Figure 5As shown, that is, a schematic diagram of the structure of pulling the veneer 10 through the conveyor roller 11 and the conveyor roller 2 12 and winding it around the winding roller 13; specifically, the processing box 1 is provided with a traction mechanism 3 that brings one end of the veneer 10 into the processing box 1 and winds it around the conveyor roller 11 and the conveyor roller 2 12, and the traction mechanism 3 includes a guide rail 30 arranged at the bottom of the processing box 1, a through slide groove is opened inside the guide rail 30, and a slider 31 is slidably arranged inside the slide groove.

[0048] One end of the veneer 10 is set on the slider 31. The slider 31 moves on the guide rail 30, and will move the veneer 10 inside the processing box 1, driving one end of the veneer 10 to move along the route of the guide rail 30, contact with the conveying roller 11 and the conveying roller 2 12, and finally clamped on the winding roller 13.

[0049] Reels 32 are disposed at both ends of the guide rail 30 , and pull ropes 33 are disposed at both ends of the slider 31 along the extending direction of the guide rail 30 . The pull ropes 33 are respectively wound around the two reels 32 .

[0050] As the reel 32 rotates, the pull rope 33 is gradually wound around it, and the slider 31 is pulled to move steadily along the guide rail 30 toward the corresponding reel 32. Through the control of the reel 32, one end of the veneer 10 is driven to move inside the processing box 1. Through the control of another reel 32, the slider 31 is driven back to the initial state to prepare for dust removal of the next veneer 10.

[0051] Both reels 32 are provided with synchronous wheels through ratchet teeth (not shown in the figure), and synchronous belts 34 are sleeved on the two synchronous wheels. The ratchet grooves of the two ratchets are opened in opposite directions. When one of the synchronous wheels rotates, it can drive the reel 32 connected to it to rotate, and then drive the slider 31 to slide on the guide rail 30 first through the pull rope 33, while the other reel 32 will not be affected by the rotation of the synchronous wheels. When it is necessary to drive the slider 31 to approach to another direction, one of the synchronous wheels rotates, and the reel 32 connected to it will not rotate, and it will drive the reel 32 connected to the other synchronous wheel to rotate, driving the slider 31 to approach to another direction, thereby realizing that the rotation of one synchronous wheel can control the sliding direction of the slider 31.

[0052] Reference Figure 3 , Figure 4 and Figure 5 As shown, that is, a schematic diagram of the structure for clamping one end of the veneer 10 during the process of conveying it; specifically, a clamping member 4 for clamping the veneer 10 is provided on the slider 31, and the clamping member 4 includes a connecting shaft 40, which is rotatably arranged on the top of the slider 31 along the height direction of the processing box 1, and a clamping block 41 is provided on the connecting shaft 40.

[0053] A clamping groove is formed on the side of the clamping block 41 , and a clamping plate 42 is rotationally symmetrically arranged inside the clamping groove via a torsion spring, and an electromagnet 43 is installed on the opposite side of the clamping plate 42 .

[0054] In the initial state, the two clamping plates 42 have a deflection tendency to rotate from the rotation point to both sides under the action of the torsion spring. When the veneer 10 needs to be clamped, one end of the veneer 10 is placed between the two clamping plates 42, and then the two clamping plates 42 are driven to rotate until the two clamping plates 42 gradually become parallel. It should be noted that the magnetic poles of the electromagnets 43 on the two clamping plates 42 are opposite. The approach of the electromagnets 43 can make the two clamping plates 42 close to clamp the veneer 10, making it convenient for the veneer 10 to move following the clamping plates 42.

[0055] When the veneer 10 is completely wound on the winding roller 13, the processed winding roller 13 needs to be taken out. At this time, the electromagnet 43 does not work, and the two clamping plates 42 rotate under the action of the torsion spring to release the clamping of the veneer 10, making it convenient to take out the winding roller 13 and the wound veneer 10.

[0056] Reference Figure 2 , Figure 6 and Figure 7 As shown, it is a schematic diagram of the structure for collecting dust on the veneer 10; specifically, the filtering mechanism 2 includes a filter box 20, and the filter box 20 is arranged inside the processing box 1. A collecting pipe 21 connected to the filter box 20 is arranged on the side of the processing box 1 away from the winding roller 13, and the processing box 1 is symmetrically provided with a collecting box 22 connected to the collecting pipe 21 along its length direction. A plurality of collecting buckets 23 connected to the interior of the processing box 1 are equidistantly and obliquely installed.

[0057] The collecting bucket 23 is responsible for collecting dust on the moving veneer 10 , and the dust is then introduced into the collecting box 22 and then enters the interior of the filter box 20 through the collecting pipe 21 .

[0058] An air pump and a plurality of filter plates 24 are sequentially arranged inside the filter box 20 along its height direction, and the filter hole diameters of the filter plates 24 decrease sequentially from top to bottom.

[0059] The suction force of the collecting hopper 23 comes from the input end of the air pump. The air mixed with dust will enter the filter box 20 through the air pump. After the dust is filtered layer by layer by the filter plate 24, the air will return to the processing box 1 again. In this way, the air filtration cycle inside the processing box 1 is realized, ensuring the cleanliness of the environment inside the processing box 1 and preventing dust from falling onto the veneer 10 and affecting the dust treatment effect.

[0060] Reference Figure 2 , Figure 6 and Figure 7As shown, it is a schematic diagram of the structure for scraping off the dust adhered to the veneer 10; specifically, a plurality of abutment plates 51 are equidistantly arranged on one side of the two collecting boxes 22 close to the veneer 10 through a rotating shaft 50, and the abutment plates 51 are arranged to be tilted in the opposite direction to the movement direction of the veneer 10. During the movement of the veneer 10, it will contact the abutment plates 51. If there is stubborn dust that cannot be adsorbed and removed, it will be scraped off by the abutment plates 51, and the abutment plates 51 correspond to the collecting buckets 23 one by one. The dust scraped off by the abutment plates 51 will be immediately absorbed by the collecting bucket 23 to prevent the dust from gathering on the collecting bucket 23 and affecting the cleanliness of the inside of the processing box 1.

[0061] The rotating shafts 50 on the same side rotate synchronously via a sprocket chain, and one of the rotating shafts 50 on the opposite side is connected via a synchronous belt 34 .

[0062] The tilt angle of the abutment plate 51 can be easily adjusted by rotating the rotating shaft 50 , and the rotation of any rotating shaft 50 on the same side can drive the other rotating shafts to rotate synchronously, ensuring that the veneer 10 will not be blocked by the abutment plate 51 before entering the processing box 1 .

[0063] Reference Figure 2 , Figure 7 and Figure 8 As shown, it is a schematic diagram of the structure that drives the winding roller 13 to rotate; specifically, a mounting plate 60 is slidably arranged above the winding roller 13 at the top of the processing box 1, and a square rod 61 is rotatably arranged on the mounting plate 60 through a matching shaft, and a matching groove that slidably matches with the square rod 61 is downwardly provided at the top of the winding roller 13. In addition, a motor is also installed on the mounting plate 60, and the output shaft of the motor is connected to the matching shaft. When the motor is started, the matching shaft is driven to rotate, thereby rotating the square rod 61. The square rod 61 cooperates with the matching groove to rotate the winding roller 13, and then moves and rolls the veneer 10 inside the processing box 1.

[0064] When the winding roller 13 of the wound veneer 10 needs to be taken out, the mounting plate 60 needs to be pushed to slide, at which time the square rod 61 cancels the cooperation with the matching groove, and an installation opening for installing the winding roller 13 is opened on the top of the processing box 1, and the winding roller 13 is taken out through the installation opening.

[0065] Reference Figure 2 , Figure 7 and Figure 8 As shown, it is a schematic diagram of the structure that drives the abutment plate 51 to be linked with the mounting plate 60; specifically, one of the rotating shafts 50 passes through the processing box 1, and a synchronous shaft 70 is rotatably mounted on the top of the processing box 1, and the synchronous shaft 70 is connected to one end of the rotating shaft 50 located outside the processing box 1 through a belt pulley. The rotation of the synchronous shaft 70 can drive the rotating shaft 50 to rotate.

[0066] A first gear 71 is also mounted on the synchronization shaft 70, a second gear 72 is rotatably mounted at the bottom of the mounting plate 60 and is movably engaged with the first gear 71, and a pull shaft 73 is threadedly mounted on the mounting plate 60 and is plugged into the second gear 72. The rotation of the pull shaft 73 drives the rotation of the second gear 72, and then the first gear 71 also starts to rotate under the drive of the second gear 72, thereby realizing the linkage of the entire transmission system.

[0067] Reference Figure 2 , Figure 7 and Figure 8 As shown, it is a schematic diagram of the structure for fixing the mounting plate 60; specifically, a socket corresponding to the pull shaft 73 is provided on the top of the processing box 1 above the winding roller 13. When the pull shaft 73 rotates, it realizes the lifting function during the rotation process by virtue of its threaded connection with the mounting plate 60. When the mounting plate 60 moves to the top of the winding roller 13 and the square rod 61 corresponds to the winding roller 13, the rotation of the pull shaft 73 will drive the pull shaft 73 to extend into the socket, which can prevent the mounting plate 60 from sliding and the square rod 61 from sliding in the process of driving the winding roller 13 to rotate, thereby affecting the winding effect of the veneer 10.

[0068] The pulling shaft 73 can also limit the second gear 72 to prevent the second gear 72 from rotating, thereby affecting the rotation of the rotating shaft 50 and preventing the contact plate 51 on the rotating shaft 50 from weakening the dust removal effect on the veneer 10 .

[0069] At the same time, the pull shaft 73 can also serve as a handle for the staff during the operation. By pulling the pull shaft 73 to move in translation, the mounting plate 60 is controlled to slide above the processing box 1.

[0070] Embodiment 2:

[0071] On the basis of the first embodiment, in order to further improve the dust collection effect, a method is proposed which is conducive to beating the moving veneer 10, which is conducive to knocking off some dust adhering to the veneer 10 and enhancing the dust collection effect on the veneer 10.

[0072] Reference Fig. 9 and Fig.10 As shown, it is a structural schematic diagram of beating the dust on the veneer 10; specifically, the beating member 8 includes a conveyor belt 80, which is arranged on one side of the inside of the processing box 1 along the width direction of the processing box 1, and a plurality of mounting blocks 81 are equidistantly arranged on the conveyor belt 80, and a beating shaft 82 is rotatably penetrated on the mounting block 81, a beating column 83 is eccentrically arranged at one end of the beating shaft 82, and a linkage gear 84 is arranged at the other end of the beating shaft 82, and a linkage rack 85 corresponding to the conveyor belt 80 is arranged at the bottom of the processing box 1, and a plurality of linkage racks 85 are all meshed with the linkage rack 85.

[0073] When the conveyor belt 80 rotates, it drives the mounting block 81 to move synchronously. At this time, the linkage gear 84 at one end of the beating shaft 82 on the mounting block 81 meshes with the linkage rack 85, driving the beating shaft 82 to rotate. The beating post 83 on the beating shaft 82 rotates accordingly, and its side surface contacts the veneer 10. Since the beating post 83 is eccentrically arranged on the beating shaft 82, the veneer 10 can be effectively beaten.

[0074] Compared with the traditional method of using a brush to remove dust stuck on the veneer, the patting method can reduce small spaces, reduce small spaces where dirt and grime hide, and improve the dust collection effect.

[0075] During operation: the first step is to place one end of the veneer 10 between the two clamping plates 42, and then bend the two clamping plates 42 to drive the two clamping plates 42 to gradually become parallel, and the two clamping plates 42 are used to clamp the veneer 10. Through the rotation of the reel 32, the pull rope 33 is driven to be gradually wound around the reel 32. The pull rope 33 will bring the slider 31 to gradually move on the guide rail 30 in the direction of the corresponding reel 32. Through the control of the reel 32, one end of the veneer 10 is driven to move inside the processing box 1, and gradually approach the winding roller 13 until the clamping block 41 is engaged with the winding roller 13.

[0076] Step 2: Push the mounting plate 60 to slide, drive the square rod 61 to cooperate with the matching groove, start the motor to drive the matching shaft to rotate, and then make the square rod 61 rotate. The square rod 61 cooperates with the matching groove to drive the winding roller 13 to rotate, and then drive the veneer 10 to move and roll inside the processing box 1.

[0077] Step 2: During the rolling process, the dust on the veneer 10 will come into contact with the abutment plate 51 , and any stubborn dust that cannot be removed by adsorption will be removed by the abutment plate 51 .

[0078] Step 4: The dust on the moving veneer 10 is collected through the collecting bucket 23, and the collected dust enters the collecting box 22. The dust in the collecting box 22 enters the filter box 20 through the collecting pipe 21, and the air mixed with dust enters the filter box 20 through the air pump. The dust is filtered layer by layer by the filter plate 24, and the air returns to the processing box 1 again, thus realizing the air filtration cycle inside the processing box 1.

[0079] Step 5: After winding is completed and dust is cleaned, push the mounting plate 60 to slide. At this time, the square rod 61 cancels the cooperation with the matching groove. An installation opening for installing the winding roller 13 is opened on the top of the processing box 1, and the winding roller 13 is taken out through the installation opening.

[0080] It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.

[0081] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
