Abstract
Description
Technical Field
[0001] This utility model relates to the field of plywood cutting technology, and in particular to a dust collection device for plywood cutting. Background Technology
[0002] Plywood, a commonly used wood processing material, is widely used in construction, furniture manufacturing, decoration, and many other industries. The production process of plywood typically involves multiple cutting and sanding operations. Since the raw material for plywood is mostly wood, the cutting process generates a large amount of sawdust, dust, and waste.
[0003] When cutting plywood, the existing cutting equipment places the plywood on the cutting table and manually pushes it to move closer to the cutting wheel. This cutting method is unsafe, and workers are prone to being accidentally injured by the cutting wheel when pushing the plywood.
[0004] The existing patent (publication number: CN220719637U) discloses a cutting device for plywood production. In operation, the plywood is placed on a support block. By extending one end of the piston rod of the fixed electric cylinder, the connecting frame and pressure plate are driven downward to press and fix the plywood. The cutting motor drives the cutting wheel to rotate. Adjusting the extension of one end of the piston rod of the electric cylinder drives the movable seat and the cutting wheel to move. The rotating cutting wheel can automatically cut the plywood during the movement, eliminating the need for workers to manually push the plywood to move. This can prevent workers from being accidentally injured by the cutting wheel and improve the production safety of plywood cutting.
[0005] Existing patents offer solutions to the above problems, but they cannot effectively collect the dust and debris generated during plywood cutting. The inability to collect dust and debris in a timely manner results in residues remaining on the plywood surface, affecting subsequent operations and causing further issues.
[0006] To address this, a dust extraction device for plywood cutting is proposed. Utility Model Content
[0007] The purpose of this invention is to provide a dust collection device for plywood cutting, which can solve the problem that existing plywood production cutting devices cannot collect and process the dust and debris generated during the plywood cutting process.
[0008] To achieve the above objectives, the present invention provides the following technical solution: a dust collection device for plywood cutting, comprising a cutting table, a cutting blade disposed in the middle of the cutting table, a top plate disposed on the top of the cutting table, a dust collection pipe disposed in the middle of the top plate, a dust collection hood disposed at the bottom of the dust collection pipe, a dust collection mechanism disposed on the top of the top plate for easy cleaning, and a support mechanism disposed on the side wall of the dust collection hood;
[0009] The vacuuming mechanism includes a negative pressure vacuum cleaner mounted on the top of the top plate. The negative pressure end of the negative pressure vacuum cleaner is provided with a cyclone separator, which is connected to the suction pipe. A cleaning cylinder is provided at the bottom of the cyclone separator, and a cleaning shaft is connected to the middle bearing of the cleaning cylinder. A cleaning impeller is provided on the side wall of the cleaning shaft. A collection assembly is provided at the bottom of the cleaning cylinder, and a drive assembly is provided at the top of the top plate.
[0010] Preferably, the collection component includes a discharge cylinder disposed at the bottom of the cleaning cylinder, a discharge shaft connected to the middle bearing of the discharge cylinder, a spiral blade disposed on the side wall of the discharge shaft, a discharge port disposed at one end of the discharge cylinder, and a dust collection cylinder installed at the bottom of the discharge port.
[0011] Preferably, the drive assembly includes a drive motor mounted on the top of the top plate, a drive wheel fixedly connected to the output end of the drive motor, a driven wheel fixedly connected to one end of both the cleaning shaft and the discharge shaft, and a transmission belt provided between the drive wheel and the driven wheel.
[0012] Preferably, the support mechanism includes two threaded cylinders rotatably connected to the middle of the top plate. A threaded rod is threadedly connected inside each threaded cylinder. A mounting plate is provided at the bottom of each threaded rod. Connecting blocks are hinged to both sides of the mounting plate. A T-shaped rod is movably connected to the middle of each connecting block. A support sleeve is fixedly connected to the side wall of the T-shaped rod. A support spring is sleeved on the top of the T-shaped rod, located between the support sleeve and the connecting block. The bottom of the T-shaped rod is fixedly connected to the dust collection hood.
[0013] Preferably, both ends of the dust collection hood are connected to rollers by bearings, and the rollers are located at the bottom of the dust collection hood.
[0014] Preferably, the dust collection hood is provided with sealing strips on both sides, and the sealing strips are in contact with the cutting table.
[0015] Preferably, a drive bar is installed on the side wall of the dust hood, and the drive bar is inclined.
[0016] Preferably, the bottom of the suction pipe is provided with a corrugated pipe, which is connected to the suction hood.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. This application incorporates a dust collection mechanism. This mechanism, through the action of a negative pressure vacuum cleaner, creates a negative pressure state inside the cyclone separator, drawing in dust generated in the cutting area and sending it through the suction pipe to the cyclone separator. The cyclone separator uses the rotation of the airflow to separate the dust and airflow. The dust settles to the bottom of the separator, while the purified airflow is discharged. As the cleaning shaft drives the cleaning impeller to rotate, the collected dust and debris are separated and cleaned out of the cyclone separator. This efficiently draws in and separates dust generated during the cutting process, achieving continuous cleaning of the cutting area, reducing dust pollution, and ensuring a clean and safe working environment.
[0019] 2. This application incorporates a support mechanism. This mechanism, through the connection of a threaded cylinder and a threaded rod, allows for height adjustment of the mounting plate and adjustment of the distance between the dust hood and the cutting table. This enables the dust hood to adapt to plywood of varying thicknesses. The cooperation of the T-shaped rod, connecting block, support sleeve, and support spring ensures that the dust hood and plywood remain in close contact at all times. This allows for height adjustment of the dust hood and ensures it remains in constant contact with the plywood surface, improving the dust collection efficiency during the cutting process.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figures 1 to 6 This utility model provides a technical solution:
[0031] A dust collection device for cutting plywood includes a cutting table 1, a cutting blade 2 disposed in the middle of the cutting table 1, a top plate 3 disposed on the top of the cutting table 1, a dust collection pipe 4 disposed in the middle of the top plate 3, a dust collection hood 5 disposed at the bottom of the dust collection pipe 4, a dust collection mechanism 6 for easy cleaning disposed on the top of the top plate 3, and a support mechanism 7 disposed on the side wall of the dust collection hood 5.
[0032] The vacuuming mechanism 6 includes a negative pressure vacuum cleaner 61 installed on the top of the top plate 3. A cyclone separator 62 is installed at the negative pressure end of the negative pressure vacuum cleaner 61. The cyclone separator 62 is connected to the vacuum pipe 4. A cleaning cylinder 63 is installed at the bottom of the cyclone separator 62. A cleaning shaft 64 is connected to the middle bearing of the cleaning cylinder 63. A cleaning impeller 65 is installed on the side wall of the cleaning shaft 64. A collection assembly 66 is installed at the bottom of the cleaning cylinder 63. A drive assembly 67 is installed at the top of the top plate 3.
[0033] Specifically, such as Figure 3As shown, the collection component 66 includes a discharge cylinder 661 disposed at the bottom of the cleaning cylinder 63. A discharge shaft 662 is connected to the middle bearing of the discharge cylinder 661. A spiral blade 663 is disposed on the side wall of the discharge shaft 662. A discharge port 664 is disposed at one end of the discharge cylinder 661. A dust collection cylinder 665 is installed at the bottom of the discharge port 664.
[0034] Specifically, such as Figure 5 As shown, the drive assembly 67 includes a drive motor 671 mounted on the top of the top plate 3. The output end of the drive motor 671 is fixedly connected to a drive wheel 672. One end of the cleaning shaft 64 and the discharge shaft 662 are both fixedly connected to a driven wheel 673. A transmission belt 674 is provided between the drive wheel 672 and the driven wheel 673.
[0035] Specifically, such as Figure 6 As shown, a corrugated pipe 11 is provided at the bottom of the suction pipe 4, and the corrugated pipe 11 is connected to the suction hood 5.
[0036] In use, during the plywood cutting process, the cutting table 1 is equipped with a cutting blade 2 in the middle. The cutting blade 2 precisely cuts the plywood. The sawdust and dust generated during the cutting process will diffuse into the working environment with the airflow. After the negative pressure vacuum cleaner 61 is started, a negative pressure zone is formed in the cyclone separator 62. The dust hood 5 is kept in a sealed fit with the cutting surface by the elastic deformation of the corrugated pipe 11. The dust hood 5 and the dust suction pipe 4 capture the dust generated during cutting in real time. When the dust-laden airflow passes through the cyclone separator 62, it is separated by centrifugal force. Under the action of the system, dust and gas separation is achieved. Wood particles settle into the cleaning cylinder 63. The drive motor 671 drives the cleaning shaft 64 and the discharge shaft 662 synchronously through the transmission belt 674. The cleaning impeller 65 rotates to scrape off the dust adhering to the inner wall of the cyclone separator 62. The spiral blade 663 transports the dust through the discharge cylinder 661 to the dust collection cylinder 665. In this way, efficient dust collection is achieved for the dust generated during the plywood cutting process. The dust and debris collected by the dust collection are collected and processed, which facilitates the cleaning of dust and debris.
[0037] Specifically, such as Figure 6 As shown, the support mechanism 7 includes two threaded cylinders 71 rotatably connected to the middle of the top plate 3. Threaded rods 72 are threadedly connected inside the threaded cylinders 71. A mounting plate 73 is provided at the bottom of the threaded rods 72. Connecting blocks 74 are hinged to both sides of the mounting plate 73. A T-shaped rod 75 is movably connected to the middle of the connecting block 74. A support sleeve 76 is fixedly connected to the side wall of the T-shaped rod 75. A support spring 77 is sleeved on the top of the T-shaped rod 75. The support spring 77 is located between the support sleeve 76 and the connecting block 74. The bottom of the T-shaped rod 75 is fixedly connected to the dust collection hood 5.
[0038] Specifically, such as Figure 6As shown, both ends of the dust hood 5 are connected to rollers 8 by bearings, and the rollers 8 are located at the bottom of the dust hood 5.
[0039] Specifically, such as Figure 6 As shown, sealing strips 9 are provided on both sides of the dust hood 5, and the sealing strips 9 are in contact with the cutting table 1.
[0040] Specifically, such as Figure 6 As shown, a drive bar 10 is installed on the side wall of the dust hood 5, and the drive bar 10 is set at an angle.
[0041] In use, the height of the mounting plate 73 is first adjusted by connecting the threaded cylinder 71 and the threaded rod 72, thereby adjusting the distance between the dust hood 5 and the cutting table 1. This allows the dust hood 5 to adapt to plywood of different thicknesses. Through the cooperation of the T-shaped rod 75, connecting block 74, support sleeve 76, and support spring 77, the dust hood 5 and the plywood are always kept in close contact. This allows for height adjustment of the dust hood 5, ensuring it remains in constant contact with the plywood surface and improving dust collection during the cutting process. When the plywood contacts the dust hood 5, it tilts... The drive bar 10 contacts the plywood first, allowing one end of the dust hood 5 to tilt up and contact the plywood. At this time, the T-shaped rod 75 compresses the support spring 77 through the support sleeve 76 and is hinged to the mounting plate 73 through the connecting block 74, allowing the T-shaped rod 75 to be finely adjusted at a certain angle. The roller 8 reduces the friction between the dust hood 5 and the plywood, and the sealing strip 9 increases the fit between the dust hood 5 and the plywood. In this way, the height of the dust hood 5 can be adjusted, ensuring that the dust hood 5 is always in contact with the surface of the plywood, thus improving the dust collection effect generated during the cutting process.
[0042] By adopting the above technical solution, the problem that existing plywood production cutting devices cannot collect and process the dust and debris generated during the plywood cutting process has been solved.
[0043] Working principle: When this application is in use, firstly, during the plywood cutting process, the cutting table 1 is equipped with a cutting blade 2 in the middle. The cutting blade 2 precisely cuts the plywood. The sawdust and dust generated during the cutting process will diffuse into the working environment with the airflow. After the negative pressure vacuum cleaner 61 is started, a negative pressure zone is formed in the cyclone separator 62. The dust hood 5 is kept in a sealed fit with the cutting surface by the elastic deformation of the corrugated pipe 11. The dust hood 5 and the dust suction pipe 4 capture the dust generated during cutting in real time. When the dust-laden airflow passes through the cyclone separator 62, the dust and air are separated under the action of centrifugal force. The wood particles settle into the cleaning cylinder 63. The drive motor 671 drives the cleaning shaft 64 and the discharge shaft 662 synchronously through the transmission belt 674. The cleaning impeller 65 rotates and scrapes off the dust adhering to the inner wall of the cyclone separator 62. The spiral blade 663 transports the dust to the dust collection cylinder 665 through the discharge cylinder 661.
[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
