Specific implementation mode

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1-10 , the present invention provides a technical solution: a new type of woodworking table saw mechanical device, including: a table saw box body 1 and a table saw main body 3; the table saw box body 1 is open at the top and bottom, legs 101 are connected to the four corners of the table saw box body 1, table saw supports 2 are equidistantly connected to the inner walls on both sides of the table saw box body 1, and the table saw main body 3 is connected to the table saw supports 2; a dust-proof component is provided on the table saw box body 1.

[0032] The table top 301 of the table saw main body 3 exposes the upper opening of the table saw box body 1, and the area of the upper opening of the table saw box body 1 is larger than that of the table top 301 of the table saw main body 3, which is convenient for sweeping the sawdust on the table top 301 into the table saw box body 1 while not affecting the woodworking cutting of the table saw main body 3.

[0033] Lifting rings 102 are equidistantly and symmetrically connected to the two side walls of the table saw box body 1, an operation opening 103 corresponding to the control panel of the table saw main body 3 is opened on the side wall of the table saw box body 1, slide rails 104 are symmetrically connected to both sides of the bottom wall of the table saw box body 1, the collection box 105 in the dust-proof component is arranged at the bottom opening of the table saw box body 1, slide bars 106 are symmetrically connected to both side walls of the collection box 105, and the slide bars 106 are slidably arranged on the slide rails 104.

[0034] A lifting ring 102 is provided on the side wall of the table saw housing 1 for lifting the entire device, facilitating the movement of the device. The control panel of the table saw main body 3 is adjusted through the operation opening 103 reserved on the side wall of the table saw housing 1, thereby controlling the table saw main body 3 to perform woodworking cutting operations. At the same time, a wiring hole for the table saw main body 3 is reserved on the side wall of the table saw housing 1. The collection box 105 is slidably arranged on the slide rail 104 of the table saw housing 1 for centrally collecting and cleaning wood chips.

[0035] A convex plate 107 is connected and provided on the side wall of the table saw housing 1. A first knob bolt 108 is threadedly connected to the convex plate 107. A cushion block 109 is connected to the end of the first knob bolt 108. The cushion block 109 is snap-connected to the collection box 105.

[0036] After the collection box 105 is installed on the slide rail 104, rotate the first knob bolt 108 to control the cushion block 109 to descend and be snap-connected to the side wall of the collection box 105 for positioning, preventing the collection box 105 from falling off during the lifting of the device.

[0037] A tripod 110 is connected and provided on the side wall of the table saw housing 1. An adjusting arm 111 is provided on the tripod 110. The adjusting arm 111 is composed of multiple connecting rods hinged by damping rotating shafts. The end of the adjusting arm 111 is hinged with a dust-proof protective cover 4 through a damping rotating shaft.

[0038] Adjust the position of the dust-proof protective cover 4 through the adjusting arm 111 so that the dust-proof protective cover 4 is located at the front end of the table saw main body 3. While not affecting the woodworking cutting operation of the table saw main body 3, the dust-proof protective cover 4 blocks the floating wood chips and makes them fall into the table saw housing 1 along the arc surface of the dust-proof protective cover 4.

[0039] A placement groove 302 is formed on the table surface 301 of the table saw main body 3. A rotating plate 303 is rotatably arranged in the placement groove 302. A positioning groove 304 is formed on the side wall of the rotating plate 303. When the rotating plate 303 is placed flat, its side wall is in the same plane as the table surface 301.

[0040] When the table saw main body 3 is working, rotate the rotating plate 303 to make it lie flat and snap into the placement groove 302. At this time, the side wall of the rotating plate is in the same plane as the table surface 301, preventing the pushing of the wood during woodworking cutting from being affected.

[0041] The dust-proof protective cover 4 in the dust-proof component is arc-shaped. A U-shaped cushion plate 401 is connected to the end wall of the dust-proof protective cover 4. A U-shaped frame 402 is snap-connected to the inner side wall of the dust-proof protective cover 4. Scrapers 403 are connected to the end wall and both side walls of the U-shaped frame 402. The scrapers 403 are in contact with the inner side wall of the dust-proof protective cover 4. Rotating rods 404 are symmetrically connected to both side walls of the U-shaped frame 402. The rotating rods 404 penetrate the side wall of the dust-proof protective cover 4.

[0042] The rotating rods 404 on both side walls of the U-shaped frame 402 penetrate through the side walls of the dust-proof protective cover 4, enabling the U-shaped frame 402 to rotate circumferentially along the arc surface of the dust-proof protective cover 4. As a result, the scraping plate 403 on the end wall of the U-shaped frame 402 scrapes against the arc surface of the dust-proof protective cover 4, and the scraping plates 403 on both side walls of the U-shaped frame 402 scrape against the two side planes of the dust-proof protective cover 4, thereby scraping off the wood chips adhering to the inner wall of the dust-proof protective cover 4.

[0043] A handle 405 is connected to the end of the rotating rod 404. A second knob bolt 406 is threadedly connected to the side wall of the handle 405. A plug post 407 is connected to the end of the second knob bolt 406. A slot 408 is formed on the side wall of the U-shaped backing plate 401, and the plug post 407 is inserted into the slot 408.

[0044] With the help of the handle 405, it is convenient to control the rotation of the U-shaped frame 402 to scrape off the wood chips on the inner wall of the dust-proof protective cover 4. At the same time, by rotating the second knob bolt 406, the plug post 407 is controlled to be inserted into the slot 408 on the side wall of the U-shaped backing plate 401 to fix the position of the U-shaped frame 402 and prevent the U-shaped frame 402 from shaking during use.

[0045] The U-shaped backing plate 401 is snap-fitted with the tabletop 301. The dust-proof protective cover 4 covers the circular saw of the table saw main body 3. A clamping plate 5 is connected to the side wall of the U-shaped backing plate 401. A rotating plate groove 501 is formed on the side wall of the clamping plate 5, and the rotating plate groove 501 is snap-fitted with the rotating plate 303.

[0046] Rotate the rotating plate 303 to expose the tabletop 301 until the rotating plate 303 abuts against the side of the placement groove 302 for positioning and moving the dust-proof protective cover 4. After the rotating plate groove 501 on the side wall of the clamping plate 5 is snap-fitted with the rotating plate 303, it is convenient to move the dust-proof protective cover 4 to a specified position so that the U-shaped backing plate 401 is snap-fitted with the tabletop 301 and the dust-proof protective cover 4 covers the circular saw of the table saw main body 3, playing a protective role to prevent the circular saw from being damaged in the non-use state.

[0047] Symmetrically arranged sliding grooves 502 are formed on both side walls of the clamping plate 5. A U-shaped moving plate 503 is snap-fitted on the side wall of the clamping plate 5. Symmetrically arranged sliding blocks 504 are connected to the inner walls of both sides of the U-shaped moving plate 503, and the sliding blocks 504 are movably snap-fitted in the sliding grooves 502. A positioning plug plate 505 is connected to the side wall of the U-shaped moving plate 503, and the positioning plug plate 505 is inserted into the positioning groove 304.

[0048] Move the sliding block 504 along the sliding groove 502 to adjust the position of the U-shaped moving plate 503 so that the positioning plug plate 505 is inserted into the positioning groove 304 to fix the position of the dust-proof protective cover 4.

[0049] A guide groove 506 is formed on the side wall of the clamping plate 5. The guide groove 506 penetrates through the sliding groove 502. A guide post 507 is connected to the inner wall of the guide groove 506. A spring 508 is sleeved on the guide post 507. A limiting plate 509 is clamped in the guide groove 506. The limiting plate 509 is sleeved on the guide post 507. The limiting plate 509 is clamped with the spring 508. The limiting plate 509 is clamped with the U-shaped moving plate 503.

[0050] The compressed spring 508 resets and pushes the limiting plate 509 to move to the end of the guide groove 506 and be clamped with the U-shaped moving plate 503, thereby limiting the U-shaped moving plate 503 to ensure stable insertion of the positioning plug 505 into the positioning groove 304. The sleeving of the limiting plate 509 on the guide post 507 prevents the limiting plate 509 from falling off.

[0051] Working principle: When the table saw main body 3 performs woodworking cutting, the position of the dust shield 4 is adjusted through the adjusting arm 111 to meet the space requirements for cutting different woods. The dust shield 4 covers the upper part of the cutting position, blocking the flying wood chips during wood cutting to prevent the wood chips from splashing and hurting people. After the wood chips hit the inner side wall of the dust shield 4, they fall into the table saw box body 1. At the same time, rotate the second knob bolt 406 to control the separation of the plug post 407 from the plug slot 408 to unlock and fix the position of the U-shaped frame 402. Rotate the U-shaped frame 402 with the handle 405 to make the scraping plate 403 scrape off the wood chips on the inner wall of the dust shield 4, and sweep the wood chips on the table top 301 into the table saw box body 1. The wood chips falling into the table saw box body 1 are collected in the collection box 105 at the bottom end of the table saw box body 1. Rotate the first knob bolt 108 to control the separation of the cushion block 109 from the collection box 105 to unlock the collection box 105, and then the collection box 105 can be pulled out from the slide rail 104, which is convenient for timely centralized treatment of the wood chips collected in the collection box 105, avoiding the influence of wood chip fluttering on other constructions and reducing the fire risk at the same time.

[0052] After the woodworking cutting of the table saw main body 3 is completed, rotate the rotating plate 303 to expose the table top 301. The rotating plate 303 abuts against the side of the placing groove 302. Move the position of the dust shield 4 so that the rotating plate groove 501 on the side wall of the clamping plate 5 is clamped with the rotating plate 303, and then the U-shaped cushion plate 401 is clamped with the table top 301. At this time, the dust shield 4 covers the circular saw of the table saw main body 3. Move the U-shaped moving plate 503 along the clamping plate 5 so that the positioning plug 505 is inserted into the positioning groove 304 until the U-shaped moving plate 503 is clamped with the rotating plate 303. The compressed spring 508 resets and pushes the limiting plate 509 to move to the end of the guide groove 506 and be clamped with the U-shaped moving plate 503, preventing the positioning plug 505 from separating from the positioning groove 304, thereby fixing the position of the dust shield 4 and achieving the protection effect on the circular saw of the table saw main body 3.
