Description

Technical Field

[0001] This utility model relates to the field of wood processing equipment technology, and more specifically, to a multi-functional table saw for wood processing. Background Technology

[0002] A table saw is a common tool used for sawing wood and other materials. Currently, table saws on the market mainly include a workbench, an electric saw, and a crossbar. Users can push wood on the workbench and the electric saw will cut and process the wood.

[0003] A search revealed that patent publication number CN210758206U discloses a multi-functional table saw, aiming to overcome the problems of limited usage and inconvenience in portability of existing table saws. The table includes a workbench with a mounting opening. A mounting frame, shaped like a solid, is suspended within the mounting opening. A dual-shaft extension motor and a centrifugal fan are fixedly installed within the mounting frame. The mounting frame includes a mounting plate with a cover, forming a storage trough between the mounting plate and the cover. A first shaft hole and a discharge hole are formed on the mounting plate, connecting the storage trough. One output shaft of the dual-shaft extension motor is fixedly connected to a circular saw blade through the first shaft hole. The centrifugal fan includes a volute housing with an air inlet, an air outlet, and a second shaft hole. Another output shaft of the dual-shaft extension motor is fixedly connected to an impeller through the second shaft hole. The discharge hole and the air inlet are interconnected. During the development of this utility model, the inventors discovered the following problems with the existing technology:

[0004] Existing table saws generate a lot of heat due to friction between the saw blade and the wood when cutting hardwood or thick boards. This causes the saw blade to deform due to heat and the blade to wear more quickly, resulting in frequent tool replacements. In addition, when cutting engineered wood or dried wood, a lot of fine dust is generated. Due to the force of the splashing during cutting, it is difficult to completely capture the suspended and splashing particles when vacuuming, which affects processing efficiency and increases costs.

[0005] Therefore, a multi-functional table saw for wood processing is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a multi-functional table saw for wood processing to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional table saw for wood processing, comprising a workbench, a spray nozzle, a protective cover, and a liquid collection tank. A saw blade is installed at the center of the upper end of the workbench, and a rotating shaft is installed in the inner cavity of the saw blade. A support frame is provided on the rear end face of the workbench, and a liquid storage tank is installed at the center of the upper end of the support frame. A liquid pump is provided on the left side of the liquid storage tank, and a liquid delivery pipe is installed at the output end of the liquid pump.

[0008] The spray nozzle is installed at the end of the liquid delivery pipe away from the liquid pump. The protective cover is installed on the upper end of the workbench. A mounting bracket is welded to the left side of the workbench. A motor is installed below the mounting bracket. A drive wheel is installed at the output end of the motor. The liquid collection tank is located on the upper end of the mounting bracket. A filter is installed on the upper end of the liquid collection tank.

[0009] Preferably, the input end of the liquid pump is connected to the liquid storage tank, and the end of the spray nozzle away from the liquid delivery pipe is tilted at 45° toward the side of the saw blade.

[0010] Preferably, the filter element is embedded in the inner surface of the upper end of the liquid collection tank, and the bottom of the liquid collection tank abuts against the upper surface of the mounting bracket.

[0011] Preferably, the protective cover has openings on both sides, and the bottom edge of the protective cover is embedded into the upper edge of the workbench to achieve a limiting position.

[0012] Preferably, the support frame is L-shaped, with its upper end extending to the upper end of the workbench, and the upper surface of the workbench has a slope of 10°.

[0013] Preferably, a driven wheel is installed at the front end of the rotating shaft, and a belt is sleeved on the outer surface of the driven wheel and the driving wheel.

[0014] Preferably, the motor is used to drive the drive wheel to rotate about its axis, and the driven wheel and the outer surface of the drive wheel are engaged with the inner surface of the belt.

[0015] Preferably, when the driven wheel rotates with the belt, it causes the saw blade to rotate in conjunction with the rotating shaft.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. Compared with existing technologies, this multi-functional table saw for wood processing directly washes the saw blade edge with fine mist from the spray nozzle, carrying away the heat generated by cutting friction, reducing tool thermal deformation, extending life, and reducing costs. The spray forms a wide-angle fog curtain to intercept suspended dust, causing the wood chips to become wet and heavier before settling, changing the direction of the wood chips and guiding them to fall into the dust collection box below for collection.

[0018] 2. Compared with existing technologies, this multi-functional table saw for wood processing can recover settled waste liquid through a collection tank, effectively guide the waste liquid generated by spray cooling and dust removal to the collection tank, and intercept sawdust through a filter. The filtered liquid can be reused after meeting the usage standards, thereby saving processing costs. Attached Figure Description

[0024] 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.

[0025] Example 1

[0026] As attached Figures 1 to 4 The multi-functional table saw for wood processing shown includes a workbench 1, a spray nozzle 11, a protective cover 12, and a liquid collection tank 15. A saw blade 2 is installed at the center of the upper end of the workbench 1. The workbench 1 provides a stable operating surface for wood cutting and bears the weight of the wood and the impact force during cutting. A rotating shaft 21 is installed in the inner cavity of the saw blade 2. The saw blade 2 and the rotating shaft 21 rotate at high speed to achieve straight cutting of the wood. A support frame 7 is provided on the rear end face of the workbench 1. A liquid storage tank 8 is installed at the center of the upper end of the support frame 7. The liquid storage tank 8 stores water. The support frame 7 supports the weight of the liquid storage tank 8 and the liquid pump 9. The liquid pump 9 is provided on the left side of the liquid storage tank 8. A liquid delivery pipe 10 is installed at the output end of the liquid pump 9. The liquid pump 9 pressurizes the liquid in the liquid storage tank 8 and delivers it to the liquid delivery pipe 10.

[0027] The spray nozzle 11 is installed at the end of the liquid delivery pipe 10 away from the liquid pump 9. The water mist generated by the spray nozzle 11 adsorbs the sawdust generated during cutting. The protective cover 12 is installed on the upper end of the workbench 1, covering the saw blade 2 to prevent splashing. A mounting frame 14 is welded to the left side of the workbench 1. The mounting frame 14 supports the weight of the liquid collection tank 15. A motor 6 is installed below the mounting frame 14. A drive wheel 4 is installed at the output end of the motor 6. The motor 6 drives the drive wheel 4 to rotate. The liquid collection tank 15 is located on the upper end of the mounting frame 14. The liquid collection tank 15 collects the waste liquid flowing down the workbench. A filter 16 is installed on the upper end of the liquid collection tank 15. The filter 16 works with the liquid collection tank 15 to filter and reuse the waste liquid, thereby achieving multi-functional cutting processing.

[0028] Example 2

[0029] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0030] In a preferred embodiment, the input end of the liquid pump 9 is connected to the liquid storage tank 8. The liquid pump 9, through its input end connected to the liquid storage tank 8, can quantitatively and continuously deliver the liquid in the liquid storage tank 8 to the liquid delivery pipe 10. The end of the spray nozzle 11 away from the liquid delivery pipe 10 is tilted at 45° toward the side of the saw blade 2. The 45° tilt allows the spray from the spray nozzle 11 to be directly aimed at the contact point between the saw blade 2 and the wood.

[0031] In a preferred embodiment, the filter 16 is embedded in the inner surface of the upper end of the liquid collection tank 15, and the filter 16 directly covers the upper end of the liquid collection tank 15. When the liquid flows in from above, the sawdust and debris are intercepted by the filter 16, and only the liquid enters the bottom of the liquid collection tank 15 through the filter holes, thereby achieving rapid solid-liquid separation. The bottom of the liquid collection tank 15 abuts against the upper end face of the mounting frame 14, and the liquid collection tank 15 is supported by the mounting frame 14 for quick removal and placement.

[0032] In a preferred embodiment, the protective cover 12 has openings 13 on both sides, through which the wood passes, allowing the spray nozzle 11 to extend to the cutting area of ​​the saw blade 2. The bottom edge of the protective cover 12 is embedded in the upper edge of the workbench 1 to achieve a limit. The protective cover 12 covers the saw blade 2 and the spraying area, preventing the spray and wood chips from spreading in all directions.

[0033] As a preferred embodiment, the support frame 7 is L-shaped, with its upper end extending to the upper end of the workbench 1. The horizontal section of the support frame 7 extends to the upper end of the workbench 1, making the installation position of the liquid storage tank 8 closer to the top of the saw blade 2. The slope of the upper surface of the workbench 1 is 10°, and the 10° slope makes the table surface of the workbench 1 form an inclined plane. The waste liquid generated by the spray dust suppression automatically flows to the low-level area where the collection tank 15 is located under the action of gravity.

[0034] In a preferred embodiment, a driven wheel 3 is installed at the front end of the rotating shaft 21. The driven wheel 3 drives the rotating shaft 21 to rotate. A belt 5 is sleeved on the outer surface of the driven wheel 3 and the driving wheel 4. The motor 6 is used to drive the driving wheel 4 to rotate around its axis. The outer surface of the driven wheel 3 and the driving wheel 4 is meshed with the inner surface of the belt 5. The belt 5 causes the driven wheel 3 and the driving wheel 4 to rotate in linkage. When the driven wheel 3 rotates with the belt 5, it causes the saw blade 2 to rotate in linkage with the rotating shaft 21. The motor 6 directly drives the driving wheel 4 and transmits power synchronously to the driven wheel 3 through the belt 5.

[0035] The working process of this utility model is as follows: First, the wood is placed on the workbench 1 and positioned using the stable plane provided by the workbench 1. The motor 6 is started, and the drive wheel 4 at the output end of the motor 6 starts to rotate. Through the transmission of the belt 5, the driven wheel 3 is driven to rotate synchronously. The driven wheel 3 then drives the rotating shaft 21 and the saw blade 2 to rotate at high speed, thereby realizing the straight cutting of the wood. During the cutting process, the liquid pump 9 starts to work. Its input end is connected to the liquid storage tank 8, which pressurizes the water stored in the liquid storage tank 8 and delivers it to the liquid delivery pipe 10. Finally, it is sprayed out from the spray nozzle 11 at an angle of 45°. The water mist sprayed from the spray nozzle 11 accurately covers the contact point between the saw blade 2 and the wood. On the one hand, it absorbs the wood dust generated during cutting and improves the working environment. On the other hand, it cools the saw blade 2. At the same time, the protective cover 12 covers the saw blade 2. The openings 13 on both sides facilitate the passage of wood and the extension of the spray nozzle 11. Its bottom is embedded in the edge of the workbench 1 to limit the spray and wood dust to spread to the surroundings.

[0036] The waste liquid generated during cutting and the wood chips adsorbed by the water mist flow along the surface of the workbench 1 with a 10° slope to the collection tank 15 under the action of gravity. The filter 16 above the collection tank 15 is embedded in its upper inner surface, which can intercept wood chips and debris, allowing only liquid to enter the bottom of the collection tank 15 through the filter holes, thus achieving solid-liquid separation. The filtered waste liquid can be recycled. The bottom of the collection tank 15 abuts against the upper surface of the mounting frame 14, which is convenient for quick removal and cleaning. Throughout the process, the L-shaped support frame 7 stably supports the storage tank 8 and the liquid pump 9. The above is the working principle of this multi-functional table saw for wood processing.
