Description

Technical Field

[0001] This invention relates to the field of dust and debris treatment technology, and in particular to a dust and debris prevention device for processing bamboo squares. Background Technology

[0002] Bamboo square material refers to bamboo material extracted from and processed from bamboo. It is lightweight, hard, corrosion-resistant, and environmentally friendly, making it widely applicable in construction, furniture, handicrafts, and decoration. Improving the appearance and texture of bamboo square material typically involves surface treatment and finishing, including sanding, polishing, and color treatment to achieve the desired smoothness and color tone. However, polishing and grinding processes usually generate a large amount of dust, which can affect the health of workers and the cleanliness of the working environment. Current dust control measures typically involve spraying water to reduce dust dispersion and installing ventilation systems to expel dust from the air. While these measures can prevent dust dispersion to some extent, they do not address the root cause of the dust problem and therefore cannot effectively prevent the impact of dust on worker health and the working environment.

[0003] Therefore, it is necessary to design a dust prevention device for bamboo square material processing that can remove dust during the processing. Summary of the Invention

[0004] To overcome the shortcomings of current dust control measures, which typically involve spraying water and installing ventilation systems, although these can prevent dust from escaping to some extent, they cannot solve the dust problem at its source and thus cannot effectively avoid the impact of dust on the health of workers and the working environment, this invention provides a dust prevention device for bamboo square material processing that can remove dust during the processing.

[0005] A dust prevention device for bamboo processing includes a mounting base, a collection drawer, a vacuum cleaner, a dust removal mechanism, and a sawdust cleaning mechanism. The collection drawer is slidably connected to the right side of the mounting base, and the vacuum cleaner is connected to the middle of the mounting base. The vacuum cleaner is equipped with a dust removal mechanism for adsorbing and cleaning the dust that is emitted. The dust removal mechanism can be fixed to the right side of the bamboo processing equipment. The vacuum cleaner is equipped with a sawdust cleaning mechanism for cleaning sawdust from the surface of the bamboo. The sawdust cleaning mechanism can be fixed at the outlet of the bamboo processing equipment.

[0006] Furthermore, the dust removal mechanism includes a magnet, a first mounting frame, a first suction nozzle, a first duct, and a partition dustproof cloth. Multiple first ducts are connected to the upper left and right sides of the vacuum cleaner, and first suction nozzles are connected between the first ducts on the same side. The first mounting frame is connected between the first suction nozzles. Magnets are connected to the upper and lower left sides of the first mounting frame. The magnets are used to attract and fix the vacuum cleaner to the bamboo processing equipment. Partition dustproof cloths are connected to the front and rear sides of the first mounting frame. The partition dustproof cloths are used to prevent dust from escaping from the sides.

[0007] Furthermore, the sawdust cleaning mechanism includes a second mounting frame, side shielding cloths, a drive assembly, a brush removal assembly, a second suction nozzle, and a second conduit. The front of the vacuum cleaner is connected to the second conduit, and the second suction nozzle is connected to the second conduit. The brush removal assembly is connected to the second suction nozzle, and the second mounting frame is slidably connected to the brush removal assembly. Bolt holes are opened on the rear side of the second mounting frame. The second mounting frame is used to install and fix it at the outlet of the bamboo square material processing equipment. Side shielding cloths are connected to both the left and right sides of the second mounting frame to prevent dust from escaping from the sides. The drive assembly is provided on the upper side of the second mounting frame to drive the brush removal assembly to move.

[0008] Furthermore, the drive assembly includes a motor and a lead screw. The motor is mounted on the upper rear side of the second mounting bracket, and the lead screw is connected to the output shaft of the motor. The lead screw is rotatably connected to the second mounting bracket, and the lead screw is threadedly connected to the brush removal assembly.

[0009] Furthermore, it also includes a dust suppression mechanism, which includes an atomizing nozzle, a first water pump, and a water tank. The atomizing nozzle is installed on the upper side of the first mounting bracket, and the water tank is installed on the left side of the mounting base. The first water pump is connected to the rear side of the water tank and is connected to the atomizing nozzle.

[0010] Furthermore, it also includes a dust cleaning mechanism, which includes a second water pump, a mounting block, a sliding frame, rollers, a first spring, and a drip nozzle. The second water pump is installed on the front side of the water tank. Mounting blocks are connected to the left and right sides of the front of the second mounting frame. A sliding frame is slidably connected between the mounting blocks. Rollers are rotatably connected to the sliding frame. The first spring is connected between the mounting blocks and the sliding frame. A drip nozzle is connected between the lower sides of the mounting blocks. The second water pump is connected to the drip nozzle.

[0011] Furthermore, it also includes a sealing mechanism, which includes a sealing plate, a connecting plate, a pressure plate, and a second spring. The sealing plate is rotatably connected to the inside of the vacuum cleaner, and the connecting plate is rotatably connected to the lower right side of the sealing plate. The pressure plate is slidably connected to the lower left inner side of the vacuum cleaner. The pressure plate contacts the collection drawer and is rotatably connected to the connecting plate. Three second springs connect the pressure plate to the vacuum cleaner.

[0012] Furthermore, it also includes a fixing mechanism, which includes a limit buckle, a mounting rod, a fixing plate, and a torsion spring. Limit buckles are welded to the front and back of the right side of the collection drawer. Mounting rods are connected to the front and back of the right side of the mounting base. Fixing plates are rotatably connected to the mounting rods. The fixing plates are engaged with the limit buckles. A torsion spring connects the mounting rods and the fixing plates.

[0013] The present invention has the following advantages: 1. The present invention uses a magnet to fix the first mounting bracket to the right side of the bamboo square material processing equipment, and uses bolt holes to fix the second mounting bracket to the outlet of the bamboo square material processing equipment. Then, the vacuum cleaner is turned on, and the dust can be adsorbed and fall into the collection drawer. Thus, the dust can be adsorbed and collected at the source, avoiding the dust from escaping and causing harm to the workers.

[0014] 2. During the grinding and processing of bamboo square material, the present invention can also start the first water pump, which will draw water from the water tank and spray it out through the atomizing nozzle, thereby effectively reducing dust and preventing dust from being raised and scattered.

[0015] 3. When the bamboo square material is moved out after grinding, it will also come into contact with the roller to clean the surface of the bamboo square material. At the same time, the second water pump can be activated to draw water from the water tank and then drip it out through the drip nozzle, thereby increasing the cleaning effect of the roller.

[0016] 4. When the collection drawer is pulled out to the right, it will disengage from the pressure plate. The second spring will then push the pressure plate to the right, which will in turn drive the sealing plate to rotate counterclockwise through the connecting plate, thereby blocking the vacuum cleaner from continuing to feed into the collection drawer. This prevents dust from falling onto the mounting base during the cleaning of the collection drawer.

[0017] 5. The present invention uses a limiting buckle to engage with a fixing plate, thereby fixing the position of the collection drawer and preventing the collection drawer from moving to the right and being pushed out under the action of the second spring. Attached Figure Description

Detailed Implementation

[0031] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0032] A dust prevention device for bamboo processing, such as Figure 1 and Figure 2 As shown, it includes a mounting base 1, a collection drawer 2, a vacuum cleaner 3, a dust removal mechanism 4, and a sawdust cleaning mechanism 5. The collection drawer 2 is slidably connected to the right side of the mounting base 1, the vacuum cleaner 3 is connected to the middle of the mounting base 1, the dust removal mechanism 4 is connected to the vacuum cleaner 3, and the sawdust cleaning mechanism 5 is provided on the vacuum cleaner 3.

[0033] like Figure 1 and Figure 3As shown, the dust removal mechanism 4 includes a magnet 41, a first mounting frame 42, a first suction nozzle 43, a first conduit 44, and a partition dustproof cloth 45. Five first conduits 44 are connected to the upper left and right sides of the vacuum cleaner 3. First suction nozzles 43 are connected between the first conduits 44 on the same side. The first mounting frame 42 is connected between the first suction nozzles 43. Magnets 41 are connected to the upper and lower left sides of the first mounting frame 42. The magnets 41 are used to attract and fix the bamboo square material processing equipment. The partition dustproof cloth 45 is connected to the front and rear sides of the first mounting frame 42. The partition dustproof cloth 45 is used to prevent dust from escaping from the side.

[0034] like Figure 1 , Figure 4 and Figure 5 As shown, the wood chip cleaning mechanism 5 includes a second mounting frame 51, a side shielding cloth 52, a drive assembly 53, a brush removal assembly 54, a second suction nozzle 55, and a second conduit 56. The front side of the vacuum cleaner 3 is connected to the second conduit 56, and the second suction nozzle 55 is connected to the second suction nozzle 56. The brush removal assembly 54 is connected to the second suction nozzle 55, and the second mounting frame 51 is slidably connected to the brush removal assembly 54. The rear side of the second mounting frame 51 has bolt holes. The second mounting frame 51 is used to install and fix at the outlet of the bamboo square material processing equipment. The left and right sides of the second mounting frame 51 are connected to the side shielding cloth 52, which is used to prevent dust from escaping from the sides. The upper side of the second mounting frame 51 is provided with the drive assembly 53, which includes a motor and a lead screw. The motor is installed on the upper rear part of the second mounting frame 51, and the output shaft of the motor is connected to the lead screw. The lead screw is rotatably connected to the second mounting frame 51, and the lead screw is threadedly connected to the brush removal assembly 54.

[0035] During the bamboo square material grinding process, the first mounting bracket 42 can be fixed to the right side of the bamboo square material processing equipment by magnet 41. Then, the vacuum cleaner 3 is started. During the bamboo square material grinding process, the scattered dust will be absorbed by the first suction nozzle 43, and then enter the vacuum cleaner 3 through the first conduit 44, and finally fall into the collection drawer 2, thus achieving the function of dust adsorption and collection, preventing dust from escaping and causing harm to the workers. At the same time, the second mounting bracket 51 can be fixed to the outlet of the bamboo square material processing equipment through the bolt holes. When the bamboo square material is moved out after grinding, it will pass through the bottom of the second mounting bracket 51. At this time, the brushing component 54 will brush up the dust stuck to the bamboo square material. At the same time, the drive component 53 is started, and the drive component 53 drives the brushing component 54 to move, thereby improving the effect of brushing up the dust stuck to the bamboo square material. Meanwhile, the second suction nozzle 55 can adsorb the dust, and then enter the vacuum cleaner 3 through the second conduit 56, and finally fall into the collection drawer 2.

[0036] like Figure 1 , Figure 6 and Figure 7As shown, it also includes a dust suppression mechanism 6, which includes an atomizing nozzle 61, a first water pump 62, and a water tank 63. The atomizing nozzle 61 is installed on the upper side of the first mounting bracket 42, and the water tank 63 is installed on the left side of the mounting base 1. The first water pump 62 is connected to the rear side of the water tank 63, and the first water pump 62 is connected to the atomizing nozzle 61.

[0037] During the grinding and processing of bamboo squares, the first water pump 62 can be started. The first water pump 62 will draw water from the water tank 63 and then spray it out through the atomizing nozzle 61, which can effectively reduce dust and prevent dust from being raised and scattered.

[0038] like Figure 1 , Figure 8 and Figure 9 As shown, it also includes a dust cleaning mechanism 7, which includes a second water pump 71, a mounting block 72, a sliding frame 73, a roller 74, a first spring 75, and a drip nozzle 76. The second water pump 71 is installed on the front side of the water tank 63. Mounting blocks 72 are connected to the left and right sides of the front of the second mounting frame 51. The sliding frame 73 is slidably connected between the mounting blocks 72. The roller 74 is rotatably connected to the sliding frame 73. The first spring 75 is connected between the mounting blocks 72 and the sliding frame 73. The drip nozzle 76 is connected between the lower sides of the mounting blocks 72. The second water pump 71 is connected to the drip nozzle 76.

[0039] When the bamboo strip is polished and moved out, it will come into contact with the roller 74, which will then squeeze the roller 74 and the sliding frame 73 to move upward. The first spring 75 is compressed, so that the roller 74 is in close contact with the bamboo strip. During the movement of the bamboo strip, the roller 74 will rotate to clean the surface of the bamboo strip. At the same time, the second water pump 71 can be activated to draw water from the water tank 63 and then drip it out through the drip nozzle 76, thereby increasing the cleaning effect of the roller 74.

[0040] like Figure 2 , Figure 10 and Figure 11 As shown, it also includes a sealing mechanism 8, which includes a sealing plate 81, a connecting plate 82, a pressure plate 83, and a second spring 84. The sealing plate 81 is rotatably connected to the inside of the vacuum cleaner 3. The connecting plate 82 is rotatably connected to the lower right side of the sealing plate 81. The pressure plate 83 is slidably connected to the lower left inner side of the vacuum cleaner 3. The pressure plate 83 contacts the collection drawer 2. The pressure plate 83 is rotatably connected to the connecting plate 82. Three second springs 84 are connected between the pressure plate 83 and the vacuum cleaner 3.

[0041] Initially, the second spring 84 is compressed. When the collection drawer 2 is full of dust, it can be pulled out to the right. At this time, the collection drawer 2 will disengage from the pressure plate 83. The second spring 84 will then push the pressure plate 83 to the right, which will then drive the sealing plate 81 to rotate counterclockwise through the connecting plate 82, thus blocking the vacuum cleaner 3 from continuing to feed into the collection drawer 2. This prevents dust from falling onto the mounting base 1 during the cleaning of the collection drawer 2. After cleaning, the collection drawer 2 can be moved to the left to reset. At this time, the collection drawer 2 will push the pressure plate 83 to move to the left to reset, the second spring 84 will be compressed, and the sealing plate 81 will rotate clockwise to reset through the connecting plate 82. At this time, the sealing plate 81 will no longer block the feeding and can guide the adsorbed dust into the collection drawer 2.

[0042] like Figure 1 and Figure 12 As shown, it also includes a fixing mechanism 9, which includes a limit buckle 91, a mounting rod 92, a fixing plate 93, and a torsion spring 94. Limit buckles 91 are welded to the front and back sides of the right side of the collection drawer 2. Mounting rods 92 are connected to the front and back sides of the right side of the mounting base 1. Fixing plates 93 are rotatably connected to the mounting rods 92. The fixing plates 93 are engaged with the limit buckles 91. A torsion spring 94 is connected between the mounting rods 92 and the fixing plates 93.

[0043] The position of the collection drawer 2 is fixed by engaging with the fixing plate 93 through the limit buckle 91, thereby preventing the collection drawer 2 from moving to the right and being pushed out under the action of the second spring 84. When it is necessary to clean the dust in the collection drawer 2, the fixing plate 93 is rotated, the torsion spring 94 is deformed, and the fixing plate 93 is disengaged from the limit buckle 91. Then the collection drawer 2 can be moved to the right and pulled out to clean the dust. After cleaning, the collection drawer 2 is reset, and the fixing plate 93 is no longer controlled. At this time, the torsion spring 94 returns to its original position, which will drive the fixing plate 93 to rotate back to its original position, so that the limit buckle 91 and the fixing plate 93 are engaged again.

[0044] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
