Description

Technical Field

[0001] This utility model relates to the field of wood cutting technology, and in particular to a wood cutting device assembly. Background Technology

[0002] A wood cutting machine is a device that uses mechanical power to drive cutting components (such as saw blades, saw strips, etc.) to cut and shape wood (solid wood boards, engineered wood boards, veneer boards). It is widely used in furniture manufacturing, decoration construction, and wood processing. Its core features are high efficiency and convenience, and it can adapt to different types of wood and cutting needs.

[0003] In existing technologies, common wood cutting machines generally fall into two categories: tabletop circular saws, which use a high-speed rotating circular saw blade as their core, with the machine body fixed to the table and equipped with a sliding push table. However, this type of cutting machine is bulky and only suitable for factories, not for smaller spaces. The second type is handheld circular saws, which use a small rotating circular saw blade and can be moved by hand for cutting. Since no workbench is required, they are suitable for construction sites and outdoor operations. However, the cutting accuracy is affected by the operator's experience, making it difficult to guarantee the cutting precision. In addition, both types of cutting machines tend to generate sawdust during operation, affecting the surrounding environment. After cutting, the cutting area needs to be cleaned regularly. Furthermore, existing wood cutting devices typically cut perpendicular to the surface of the wood board, making it difficult to flexibly adjust the cutting direction.

[0004] Therefore, it is necessary to improve the existing wood cutting devices. Utility Model Content

[0005] The purpose of this utility model is to overcome the defects in the existing technology and provide a wood cutting device assembly that ensures cutting accuracy, is flexible and convenient to use, allows for adjustable cutting direction and angle, and reduces cleaning workload.

[0006] To achieve the above-mentioned technical effects, the technical solution of this utility model is: a wood cutting device assembly, comprising: The tooling assembly includes tooling units distributed in a horizontal direction. The tooling units are used to clamp a wooden board. In the clamped state, the length direction of the wooden board is parallel to the distribution direction of the tooling units, and the width direction is vertical. A cutting device, disposed on one side of the tooling assembly, includes: The movable component includes a base frame, a telescopic rod mounted on the base frame and axially vertical, and casters mounted at the bottom end of the telescopic rod. A cutting assembly, located above the base frame, includes a saw shell, a saw disc, and a rotating unit. One side of the saw shell is open, and the saw disc protrudes from the open side of the saw shell. The rotating unit drives the saw disc to rotate. A guiding assembly is disposed between the saw shell and the base frame, including a guiding frame, a filter unit and a fan. The guiding frame is connected to the telescopic rod and is provided with guide wheels that are distributed along the length direction of the open side of the saw shell, are axially vertical and rotate around their own axis. The guide wheels are used to abut against one side of the wooden board in the clamped state. The air inlet of the fan is connected to the inner cavity of the saw disc through the filter unit, and the other end faces away from the open side of the saw shell. The operating assembly includes a ball joint and an operating lever, the operating lever being connected to the base frame via the ball joint.

[0008] Preferably, to ensure cutting accuracy, calibration slide rods are provided on both sides of the saw shell. The axis of the calibration slide rod is perpendicular to the open side of the saw shell, and the centerline of the axis is located in the same plane as the saw disc. The two ends of the movement path of the calibration slide rod are a calibration station and a storage station, respectively. In the calibration station, the two ends of the calibration slide rod are located on both sides of the plane where the open side of the saw shell is located. In the storage station, the calibration slide rod is located on the side of the plane where the open side of the saw shell is located, closer to the saw shell.

[0009] Preferably, in order to facilitate the adjustment of the position of the fixed calibration slide bar, the saw shell is also connected to a calibration positioning component and a storage positioning component, which are used to position the calibration slide bar at the calibration station and the storage station, respectively.

[0010] Preferably, to further ensure cutting accuracy, the two guide wheels located at the end positions are two calibration end wheels, and the two calibration slide rods are located above the two calibration end wheels.

[0011] Preferably, in order to ensure that the open side of the saw shell can be close to the wooden board during the cutting process, an adjusting frame is slidable on the guide frame. The sliding direction of the adjusting frame is horizontal and perpendicular to the length direction of the open side of the saw shell. A first locking unit for locking the guide frame is provided between the adjusting frame and the guide frame. The guide wheel rotates on the adjusting frame around its own axis.

[0012] Preferably, in order to facilitate regular cleaning of sawdust in the filter unit, the filter unit includes a filter shell disposed on the guide frame and a filter element detachably disposed in the filter shell. The filter element and the filter shell enclose an air inlet chamber communicating with the inner cavity of the saw shell and an air outlet chamber communicating with the input end of the blower.

[0013] Preferably, in order to clean the filter element inside the filter housing and promptly remove the wood chips inside the filter housing, the filter housing includes a filter cover with an open bottom and a filter cap detachably disposed at the opening of the filter cover. The filter element is a filter barrel with an open top, which is sandwiched between the top of the filter cover and the filter cap. The outer circumferential edge of the filter barrel and the inner wall of the filter housing form an annular air outlet chamber.

[0014] Preferably, to facilitate flexible adjustment and fixation of the operating lever angle, the spherical joint includes a fixed shell and a ball bearing. The fixed shell has a rotating cavity and an opening communicating with the rotating cavity. The ball bearing includes a sphere and a locking block. The sphere has a communicating compression channel and a locking channel, and its outer surface is in contact with the cavity wall of the rotating cavity. The locking channel extends to the outer surface of the sphere. The locking block is slidably connected to the sphere through the locking channel. The operating lever includes an operating tube fixedly connected to the sphere and communicating directly with the compression channel, a locking rod connected to the inner wall of the operating tube, and a compression rod slidably connected to the operating tube and extending into the sphere. The end of the compression rod away from the locking rod is in contact with the locking block, and the contact surface is a plane that forms an angle with the sliding direction of the locking block and the axial direction of the compression rod.

[0015] Preferably, to facilitate locking and fixing the wooden board so that the length direction of the wooden board is parallel to the horizontal direction, the tooling unit includes a vertical plate, a lower clamping groove, an upper clamping groove, a sliding frame, a second locking bolt, and a third locking bolt.

There are two third locking bolts, which are used to lock the top and bottom of the wooden board to the inner wall of the upper clamping groove away from the vertical plate and the inner wall of the lower clamping groove away from the vertical plate, respectively.

[0016] In summary, compared with the prior art, the wood cutting device assembly of this utility model clamps the wood board to keep the wood board horizontal in the length direction. At the same time, the cutting component drives the cutting component to cut the wood board through the moving component. In conjunction with the fan, the debris generated by the saw blade during cutting is sucked into the filter unit. The exhaust gas is sprayed out in the opposite direction to the wood board, ensuring that the guide wheel is in contact with the surface of the wood board, ensuring cutting accuracy and saw blade service life, while also taking into account ease of use.

Detailed Implementation

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0019] like Figures 1-19 As shown, the present invention provides a wood cutting device assembly, comprising: Tooling assembly 1 includes tooling units 11 distributed in a horizontal direction. Tooling units 11 are used to clamp wooden boards 6. In the clamped state, the length direction of wooden boards 6 is parallel to the distribution direction of tooling units 11, and the width direction is vertical. A cutting device, disposed on one side of tooling assembly 1, includes: The movable component 2 includes a base frame 21, a telescopic rod 22 mounted on the base frame 21 and vertically axially, and a caster wheel 23 mounted at the bottom of the telescopic rod 22. The cutting assembly 3 is located above the base frame 21 and includes a saw shell 31, a saw disc 32 and a rotating unit 33. One side of the saw shell 31 is open, and the saw disc 32 protrudes from the open side of the saw shell 31. The rotating unit 33 drives the saw disc 32 to rotate. The guide assembly 4 is located between the saw shell 31 and the base frame 21. It includes a guide frame 41, a filter unit 42 and a fan 43. The guide frame 41 is connected to the telescopic rod 22 and is provided with guide wheels 45 that are distributed along the length of the open side of the saw shell 31, are axially vertical and rotate around their own axis. The guide wheels 45 are used to abut against one side of the wooden board 6 in the clamped state. The air inlet end of the fan 43 is connected to the inner cavity of the saw disc 32 through the filter unit 42, and the other end faces away from the open side of the saw shell 31. The operating component 5 includes a ball joint 51 and an operating lever 52, with the operating lever 52 connected to the base frame 21 via the ball joint 51.

[0020] In use, the wood cutting device assembly of this utility model first adjusts the number and distribution of the tooling units 11 according to the length of the wood board 6. The tooling units 11 clamp the wood board 6, fixing its position so that its length and thickness are horizontal, while its width is vertical. Figure 1 and Figure 2 As shown.

[0021] After clamping the wooden board 6 using the tooling unit 11, adjust the position of the cutting device. In the cutting device of this utility model, such as... Figure 5 and Figure 6 As shown, the moving component 2, the guiding component 4, and the cutting component 3 are arranged sequentially from bottom to top. The moving component 2 facilitates the movement of the device, and the operating component 5 allows the user to adjust the position of the device so that the guide wheel 45 in the guiding component 4 is tangent to one side of the wooden board 6. Then, the cutting device is started, and the user holds the operating lever 52 in the operating component 5 to push the device to move. At the same time, the rotating unit 33 in the cutting component 3 drives the saw disc 32 to rotate at high speed, and the blower 43 keeps running.

[0022] like Figure 3As shown, the cutting device moves from the end of the wooden board 6 and uses the rotating saw blade 32 to cut the wooden board 6. During the cutting process, the blower 43 draws air from the inner cavity of the saw shell 31, allowing external air to enter the saw shell 31. At the same time, the saw blade 32 can suck the wood chips into the filter unit 42, which filters out the wood chips from the airflow. The airflow then exits from the outlet of the blower 43, forming an airflow that is away from the wooden board 6. This airflow acts on the cutting device, causing the guide wheel 45 in the cutting device to abut against the surface of the wooden board 6, preventing the saw blade 32 from detaching from the wooden board 6 and ensuring cutting accuracy.

[0023] During the cutting process, the fan 43 remains running, guiding external air continuously into the saw casing 31. This not only cools the saw disc 32 but also draws the sawdust produced during cutting into the filter unit 42, reducing flying debris and thus lessening the amount of cleaning required from the user after cutting. Furthermore, compared to a tabletop circular saw, this device allows for convenient arrangement by the user through the tooling unit 11 to fix the wooden board 6, requiring less floor space. The position of the cutting device can be easily adjusted using the operating component 5 in conjunction with the moving component 2, making it convenient and quick to use while ensuring cutting accuracy.

[0024] To facilitate the fastening of the wooden board 6, the tooling unit 11 includes a vertical plate 111, a lower clamping groove 112, an upper clamping groove 113, a sliding frame 114, a second locking bolt 115, and a third locking bolt 116. The vertical plate 111 extends vertically. The lower clamping groove 112 is fixed to the vertical plate 111 with its opening facing upward. The upper clamping groove is fixedly connected to the sliding frame 114 with its opening facing downward. The sliding frame 114 slides vertically on the vertical plate 111. The width of both the upper clamping groove 113 and the lower clamping groove 112 is greater than the thickness of the template. The second locking bolt 115 is used to lock the upper clamping groove 113 to the vertical plate 111. There are two third locking bolts 116, which are used to lock the top and bottom of the wooden board 6 to the inner wall of the upper clamping groove 113 away from the vertical plate 111 and the inner wall of the lower clamping groove 112 away from the vertical plate 111, respectively.

[0025] More specifically, such as Figures 2-4As shown, the tooling unit 11 also includes a horizontal plate 117, which is horizontally arranged. Both the horizontal plate 117 and the vertical plate 111 are elongated. The horizontal plate 117 and the lower clamping groove 112 are integrally fixedly connected to the bottom sides of the vertical plate 111. The length direction of the horizontal plate 117 is perpendicular to the extension direction of the lower clamping groove 112. The vertical plate 111 is provided with a vertical sliding opening 1111 extending along its length direction. The vertical sliding opening 1111 is a through hole. The circumferential outer edge of the vertical plate 111 is sealed and fitted with the circumferential inner wall of the sliding frame 114, so as to facilitate the sliding frame 114 to slide along the vertical plate 111. The upper clamping groove 113 is integrally fixed to one side of the sliding frame 114. The opening of the upper clamping groove 113 faces downward, and the opening of the lower clamping groove 112 faces upward. The upper clamping groove 113 and the lower clamping groove 112 are integrally fixed to the lower side of the sliding frame 114. The grooves 112 have the same length direction, both perpendicular to and horizontal to the length direction of the horizontal plate 117. The axial directions of the two second locking bolts 115 are parallel to the length direction of the horizontal plate 117. The lower second locking bolt 115 faces the lower groove 112 and is threadedly connected to the vertical plate 111, with its rod extending into the lower groove 112. The upper second locking bolt 115 faces the upper groove 113 and is threadedly connected to the sliding frame 114, with its rod penetrating the sliding frame 114 and the vertical sliding opening 1111 and extending into the upper groove 113. There are two third locking bolts 116 facing each other, distributed on both sides of the sliding frame 114, with their axial direction parallel to the length direction of the upper groove 113, and their centerline intersecting perpendicularly with the two side walls of the vertical plate 111.

[0026] With the above structure, the horizontal plate 117 increases the contact area between the tooling unit 11 and the ground, preventing the tooling unit 11 from tipping over. In use, place the bottom ends of the horizontal plate 117 and the vertical plate 111, and the lower clamping groove 112 on the ground. Loosen the second locking bolt 115 and the third locking bolt 116, slide the upper clamping groove 113 upwards, and place the wooden board 6 between the upper clamping groove 113 and the lower clamping groove 112, ensuring the bottom of the wooden board 6 is flush with the inner bottom wall of the lower clamping groove 112. Slide the sliding frame 114 downwards until the inner bottom wall of the upper clamping groove 113 is in contact with the top of the wooden board 6. Then tighten the third locking bolt 116 to secure the sliding frame 114 and the upper clamping groove 113. Next, tighten the second locking bolt 115 so that the bottom of the wooden board 6 is clamped between the inner wall of the lower clamping groove 112 away from the vertical plate 111 and the lower second locking bolt 115, and the top is clamped between the inner wall of the upper clamping groove 113 away from the vertical plate 111 and the upper second locking bolt 115. By performing the above operations on multiple tooling units 11, the clamping and fixing operation of the wooden board 6 is completed.

[0027] It should be noted that in this utility model, the number and position of the tooling units 11 can be adjusted according to the specific length of the wooden board 6. The tooling units 11 are distributed along the groove length direction of the upper clamping groove 113, and the distribution spacing is smaller than the length of the vertical plate 111 and larger than the length of the horizontal plate 117. On the one hand, this ensures the fastening effect on the wooden board 6, and on the other hand, it avoids the need to perform corresponding fastening operations on too many tooling units 11, thereby increasing the user's workload and reducing cutting efficiency.

[0028] After the wood board 6 has been cut using the cutting device, loosen the second locking bolt 115 below to remove the cut wood board 6.

[0029] The saw disc 32 is detachably installed inside the saw housing 31 and protrudes from the open side of the saw housing 31. The output end of the rotating unit 33 extends into the saw housing 31 and is detachably connected to the saw disc 32 to facilitate the replacement of the saw disc 32.

[0030] Specifically, such as Figure 8 and Figure 9 As shown, the saw casing 31 includes a casing 311 and a casing bottom 312 connected to the casing 311 by four first screws 313. The rotating unit 33 includes a rotating motor 331, which is fixed above the casing 311 and has its output end extending downward through the top of the casing 311. A turntable 332 is fixedly connected to the output end. A docking post 333 is fixed to the end of the turntable 332 facing away from the rotating motor 331. Five docking posts 333 are provided, one of which is coaxial with the output end of the rotating motor 331, and the other two are arranged in a ring array on the turntable 332. The saw disc 32 includes a disc-shaped thickened portion 322 and a cutting portion 321 integrally formed on the outer circumferential edge of the thickened portion 322 with a coaxial center line and a thickness less than that of the thickened portion 322. The outer circumferential edge of the cutting portion 321 is provided with a ring array of saw teeth. The thickened portion 322 is provided with docking holes 3221 that correspond one-to-one with the docking posts 333 and are inserted into each other. A bearing 37 is provided on the side of the bottom shell 312 adjacent to the rotating unit 33. The outer ring of the bearing 37 is fixed on the bottom shell 312, the inner ring abuts against the bottom surface of the thickened portion 322, and the top surface of the thickened portion 322 abuts against the turntable 332.

[0031] With the above structure, the first screw 313 enables a quick and easy detachable connection between the housing 311 and the housing bottom 312, facilitating the replacement and maintenance of the saw disc 32. The saw disc 32 is connected to the rotary motor 331 by the mating hole 3221 on the thickened part 322 and the mating hole 3221 on the turntable 332, enabling a quick and easy detachable connection between the saw disc 32 and the rotary motor 331. Furthermore, the bearing 37 is clamped between the thickened part 322 and the housing bottom 312 to prevent changes in the axial height position of the turntable 332, ensuring the stable rotation of the turntable 332 and thus helping to ensure cutting accuracy.

[0032] The moving component 2 of the cutting device, such as Figure 10 As shown, the base frame 21 is used to install the telescopic rods 22. There are four telescopic rods 22, which are located at the four corners of the base frame 21. The bottom end of the telescopic rods 22 is equipped with casters 23, which facilitate the sliding of the base frame 21 in the cutting device in any direction. One end of the telescopic rod 22 is connected to the base frame 21, and the other end is connected to the guide frame 41. The telescopic rods 22 facilitate the adjustment of the height position of the guide frame 41 and the cutting component 3, so that the wooden board 6 can be cut into different widths and shapes after it is fixed.

[0033] For the specific structure of the telescopic rod 22, please refer to Figure 11 and Figure 12 The telescopic rod 22 includes three support tubes 24 on the same axis (of course, the number of support tubes 24 can also be multiple). The inner diameter and outer diameter of the three support tubes 24 decrease sequentially. In two adjacent support tubes 24, the circumferential inner wall of the thicker support tube 24 is sealed and fitted with the circumferential outer edge of the thinner support tube 24. The circumferential inner wall of the thicker support tube 24 is provided with a groove 241 extending along its axial direction. There is a gap between the bottom end of the groove 241 and the bottom end of the support tube 24. The top end of the circumferential outer edge of the thinner support tube 24 is provided with a protruding key 242 that slides with the groove 241. In this way, the sliding fit between the two adjacent support tubes 24 can be achieved at the same time as the limiting connection between the two, preventing the two adjacent support tubes 24 from separating.

[0034] In two adjacent support tubes 24, a fixing sleeve 25 is fixed to the outer circumferential edge of the bottom end of the thicker support tube 24. A notch 252 is provided on one side of the fixing sleeve 25. A central shaft 251 is fixedly connected to the fixing sleeve 25 and is axially parallel to the axis of the support tube 24. A concentric sleeve 27 is provided on the outer sealing sleeve of the central shaft 251. A locking arm 26 is integrally connected to the concentric sleeve 27. The locking arm 26 is used to fit against the outer circumferential edge of the thicker support tube 24. An eccentric protrusion 28 is integrally connected to the outer axial edge of the concentric sleeve 27. The eccentric protrusion 28 is used to lock the tube wall of the thicker support tube 24 onto the tube wall of the thinner support tube 24.

[0035] With the above structure, the locking arm 26 can easily drive the concentric sleeve 27 and the eccentric protrusion 28 to rotate. After the eccentric protrusion 28 is rotated to disengage from the notch 252, the relative sliding of the two adjacent support tubes 24 can be facilitated to adjust the length of the telescopic rod 22. After the adjustment is completed, the locking arm 26 is rotated so that the locking arm 26 abuts against the outer edge of the thicker support tube 24. At the same time, the eccentric protrusion 28 rotates into the notch 252 and squeezes the thicker support tube 24, thereby achieving a locking connection between the walls of the two adjacent support tubes 24 and preventing relative axial displacement of the two support tubes 24, which is beneficial for locking the length of the telescopic rod 22.

[0036] Of the three support tubes 24 of the telescopic rod 22 of this utility model, the support tube 24 at the bottom, that is, the one with the smallest diameter, is connected to the universal wheel 23, and the support tube 24 at the top, that is, the one with the largest diameter, is fixedly connected to the guide frame 41 by the second screw 29, thereby facilitating the adjustment of the height position of the guide frame 41 and the cutting component 3.

[0037] A further improvement is that the saw shell 31 rotates above the guide frame 41 and the axis of rotation extends along the length direction parallel to the open side of the saw shell 31. The guide assembly 4 also includes a rotating unit 46, which drives the saw shell 31 to rotate.

[0038] By setting the rotating unit 46, the angles of the saw shell 31 and the saw disc 32 can be easily adjusted, so that the device can form cut surfaces with different angles after cutting the wooden board 6 to meet different usage requirements.

[0039] like Figures 16-18 As shown, in this utility model, the guide frame 41 includes a horizontal bracket 411. At the four corners of the top surface of the bracket 411, a positioning frame 413 is fixedly connected to it via a connecting frame 412. The positioning frame 413 is a tubular structure that is vertical in the axial direction, closed at the top, and open at the bottom. The outer edge of the topmost support tube 24 is sealed and fitted to the inner wall of the positioning frame 413 and is fixedly connected to the top of the support tube 24 via a second screw 29.

[0040] To achieve angle adjustment of the saw shell 31, a rotating seat 414 is fixed above the guide frame 41. The shell bottom 312 rotates on the top of the rotating seat 414. The rotating unit 46 includes a lead screw 461, a threaded sleeve 462, a slide rail 463, a bushing 464, a knob 465, and a support rod 466. The bushing 464 and the slide rail 463 are both fixed above the bracket 411. The axial direction of the lead screw 461 and the length direction of the slide rail 463 are both horizontal and perpendicular to the length direction of the open side of the saw shell 31. One end of the lead screw 461 rotates inside the bushing 464, and the other end is fixedly connected to the knob 465. The threaded sleeve 462 is threaded on the outside of the lead screw 461 and slides with the slide rail 463. The slide rail 463 is hinged to the shell bottom 312 through the support rod 466.

[0041] With the above structure, by rotating the knob 465, the lead screw 461 can be driven to rotate under the support of the bushing 464. The lead screw 461 acts on the bushing 464 through the thread, so that the bushing 464 slides under the sliding cooperation of the slide rail 463. Through the support rod 466 acting on the bottom of the shell 312, the saw shell 31 rotates, and the direction and position of the saw disc 32 are adjusted, so that when the cutting device cuts the wooden board 6, it can form cuts at different angles and positions at the cutting point.

[0042] A further improvement is that calibration slide rods 34 are provided on both sides of the saw shell 31. The axis of the calibration slide rod 34 is perpendicular to the open side of the saw shell 31 and the axis is located on the same plane as the saw disc 32. The two ends of the movement path of the calibration slide rod 34 are the calibration station and the storage station, respectively. In the calibration station, the two ends of the calibration slide rod 34 are located on both sides of the plane where the open side of the saw shell 31 is located. In the storage station, the calibration slide rod 34 is located on the side of the plane where the open side of the saw shell 31 is located, closer to the saw shell 31.

[0043] With this design, before cutting after securing the wooden board 6, the cutting device is moved to one end of the wooden board 6, the length of the telescopic rod 22 is adjusted, and the angle of the saw shell 31 is adjusted by the rotating unit 46. The calibration slide rod 34 near the end of the wooden board 6 is moved to the calibration position, so that the calibration slide rod 34 abuts against the end of the wooden board 6, and at the same time, the guide wheel 45 abuts against the side of the wooden board 6 facing away from the horizontal plate 117. Figure 3 As shown, at this time, the user can observe the cutting position of the cutting device on the wooden board 6 through the calibration slide bar 34. By observing whether the position conforms to the predetermined cutting position, the user can adjust the length of the telescopic rod 22 and adjust the rotating unit 46 to ensure that the calibration slide bar 34 is on the same plane as the predetermined cutting position, thereby ensuring the cutting accuracy.

[0044] A further improvement is that the saw shell 31 is also connected to a calibration positioning component 35 and a storage positioning component 36, which are used to position the calibration slide bar 34 at the calibration station and the storage station, respectively.

[0045] This design allows for easy adjustment and fixation of the calibration slide bar 34 according to different needs. Specifically, before cutting, the calibration slide bar 34 is slid to the calibration station and its position is fixed by the calibration positioning piece 35, which facilitates calibration of the cutting position. After calibration, the calibration slide bar 34 is slid to the storage station and its position is fixed by the storage positioning piece 36, which facilitates the cutting device to avoid the cutting board 6.

[0046] Furthermore, such as Figure 8 and Figure 9As shown, calibration grooves 3111 are provided on the two opposite outer side walls of the housing 311. The calibration grooves 3111 extend perpendicularly to the plane of the open side of the saw shell 31 and are through grooves. A stop bar 3112 of the same length as the calibration groove 3111 is also fixed to the two outer side walls of the housing 311 near the open side of the saw shell 311. The circumferential outer edge of the calibration rod 34 is sealed and fitted to the stop bar 3112 and the inner wall of the calibration groove 3111, facilitating the calibration rod 34 to move along its own length. The calibration slide bar 34 moves along its length direction. A protrusion 341 is fixed to the side of the saw shell 31 facing away from the open side. The protrusion 341 is an iron sheet. The lengths of the stop bar 3112, the calibration slide bar 34, and the calibration groove 3111 increase sequentially. The calibration positioning component 35 and the storage positioning component 36 are both magnets. The calibration positioning component 35 is fixed to the end of the stop bar 3112 away from the open side of the saw shell 31, and the storage positioning component 36 is fixed to the end of the calibration groove 3111 away from the open side of the saw shell 31.

[0047] With the above structure, the calibration slide 3111 facilitates the movement of the calibration slide 34, the protrusion 341 facilitates the control of the movement of the calibration slide 34, and the calibration positioning member 35 and the storage positioning member 36, made of magnets, facilitate the adsorption and fixation of the protrusion 341 to fix the position of the calibration slide 34. When the protrusion 341 is in contact with the calibration positioning member 35, the calibration slide 34 is located in the calibration position, with one end protruding out of the calibration slide 3111, which facilitates the calibration of the cutting position. When the protrusion 341 is released from the storage positioning member 36, the calibration slide 34 is located in the storage position, with both ends located between the two ends of the calibration slide 3111, which facilitates the cutting device to cut the wooden board 6.

[0048] A further improvement is that the two guide wheels 45 located at the ends are two calibration end wheels, and the two calibration slide bars 34 are located above the two calibration end wheels.

[0049] With the upward design, after clamping the wooden board 6, when the cutting device is brought close to the wooden board 6 and the end cutting position of the wooden board 6 is calibrated by the calibration slide 34, one end of the calibration wheel 45 still rests against the side of the wooden board 6 facing away from the horizontal plate 117. Figure 3 As shown, under these circumstances, the calibration accuracy of the cutting position can be guaranteed.

[0050] A further improvement is that an adjustment frame 44 slides on the guide frame 41. The sliding direction of the adjustment frame 44 is horizontal and perpendicular to the length direction of the open side of the saw shell 31. A first locking unit 47 for locking the guide frame 41 is provided between the adjustment frame 44 and the guide frame 41. The guide wheel 45 rotates on the adjustment frame 44 around its own axis.

[0051] This design is primarily based on the fact that after adjusting the angle of the saw shell 31 via the rotating unit 46, the position of the open side of the saw shell 31 changes. Since the guide wheel 45 is required to rest against the wooden board 6 during cutting, changing the position of the adjusting bracket 44 alters the horizontal distance between the guide wheel 45 and the open side of the saw shell 31. This ensures that the axis of the guide wheel 45 is close to the side of the open side of the saw shell 31 closest to the rotating unit 33, guaranteeing that the outer circumferential edge of the guide wheel 45 is in contact with the wooden board 6, and that the open side of the saw shell 31 is in close proximity to the wooden board 6. During the cutting process, after the blower 43 is running, most of the debris generated by the saw blade 32 after cutting is sucked into the saw shell 31, avoiding excessive gap between the two causing most of the saw chips to fly around and increasing the user's cleaning workload. On the other hand, since the distance between the open side of the saw shell 31 and the wooden board 6 is shortened, the blower 43 can generate suction on the open side of the saw shell 31 during cutting, attracting the saw shell 31 closer to the wooden board 6, so that the guide wheel 45 keeps against the wooden board 6, further ensuring the cutting accuracy.

[0052] Specifically, such as Figures 16-18 As shown, the guide frame 41 also includes two guide frames 415 fixed on the bracket 411. The two guide frames 415 extend horizontally along the length direction perpendicular to the open side of the saw shell 31 and are arranged side by side. The adjustment frame 44 includes an integrally connected adjustment frame 441, a sliding plate 442, and a protruding plate 443. The length direction of the adjustment frame 441 is parallel to the length direction of the open side of the saw shell 31, and the width direction is parallel to the length direction of the guide frame 415. The length dimension is greater than the length dimension of the bracket 411, and the thickness dimension is smaller than the outer diameter of the guide wheel 45. The wheels 45 are distributed along the length of the adjusting frame 441 and rotate around their own axis within the adjusting frame 441. Two slide plates 442 are provided and slide in one-to-one with two guide frames 415. One end of the slide plate 442 is fixedly connected to the adjusting frame 441, and the other end is connected to a protruding plate 443 to prevent the slide plate 442 from disengaging from the guide frame 415. The first locking unit 47 includes a first locking bolt threadedly connected to the guide frame 415. The axial direction of the first locking bolt is parallel to the length of the adjusting frame 441.

[0053] With the above structure, loosen the first locking bolt to allow the slide plate 442 to slide along the length direction parallel to the guide frame 415 under the guidance of the guide frame 415. Adjust the position of the adjustment frame 441 and the guide wheel 45. After the adjustment is completed, tighten the first locking bolt to prevent the slide plate 442 from sliding, thereby locking the adjustment frame 441.

[0054] A further improvement is that the filter unit 42 includes a filter housing 421 disposed on the guide frame 41 and a filter element 422 detachably disposed in the filter housing 421. The filter element 422 and the filter housing 421 enclose an air inlet chamber that communicates with the inner cavity of the saw shell 31 and an air outlet chamber that communicates with the input end of the fan 43.

[0055] With the above design, after the device has been used for a period of time, the filter element 422 inside the filter shell 421 can be removed, the inside of the filter shell 421 and the filter element 422 can be cleaned to remove the absorbed wood chips, and then the filter element 422 can be put back into the filter shell 421. This ensures that after the fan 43 is running, it can draw in external air and pass through the saw shell 31 and the filter shell 421 in sequence, thus collecting the wood chips in the airflow inside the filter shell 421.

[0056] A further improvement is that the filter housing 421 includes a filter cover 4211 with an open bottom and a filter cover 4212 detachably disposed at the opening of the filter cover 4211. The filter element 422 is a filter barrel with an open top. The filter barrel is sandwiched between the top of the filter cover 4211 and the filter cover 4212. The outer circumferential edge of the filter barrel and the inner wall of the filter housing 421 enclose an annular air outlet chamber.

[0057] More specifically, such as Figure 18 and Figure 19 As shown, in the filter unit 42, the filter cover 4211 is fixedly inserted through the bracket 411, and the top of the filter cover 4212 is fixed with a lower positioning cylinder 4213. The outer circumferential edge of the lower positioning cylinder 4213 is threadedly connected to the inner circumferential wall of the bottom of the filter cover 4211. The inner top of the filter cover 4211 is coaxially fixed with an upper positioning cylinder 4214. The filter element 422 is a filter barrel with an open top and a closed bottom. The outer circumferential edge of the bottom of the filter barrel is sealed to the inner circumferential wall of the lower positioning cylinder 4213, and the inner circumferential wall of the top is sealed to the outer circumferential edge of the upper positioning cylinder 4214. The filter element 422 is fitted with its inner top wall and the filter cover 4212 at both ends. The outer diameter of the filter element 422 is smaller than the inner diameter of the filter cover 4211, so that after the filter element 422 is installed between the filter cover 4212 and the filter cover 4211, a cylindrical air inlet chamber and an air outlet chamber with its coaxial centerline located outside the air inlet chamber are formed. The input end of the fan 43 is connected to the side wall of the filter cover 4211 to realize the communication between the input end of the fan 43 and the air outlet chamber. A corrugated hose 423 is provided at the top of the filter cover 4211, and the bottom of the shell 312 (such as...) Figure 9 The bottom of the filter element 422 (as shown) is provided with a suction port 3121. The top of the corrugated hose 423 is connected to the suction port 3121, and the bottom is connected to the air intake chamber through the through hole at the top of the filter cover 4211. The outer circumferential edge of the filter element 422 is densely covered with filter mesh holes, and the bottom is fixed with a screw 4215 that penetrates the filter cover 4212. The screw 4215 is threadedly connected to a nut 4216.

[0058] With the above structure, the deformation of the corrugated hose 423 facilitates the angular rotation of the saw shell 31. After the blower 43 is running, the external air carries the saw chips into the saw shell 31 through the open side of the saw shell 31, and then enters the air intake chamber through the through holes at the top of the corrugated hose 423 and the filter cover 4211. The saw chips are intercepted by the filter element 422 with dense mesh, while the air flows to the outer air outlet chamber and is discharged by the blower 43, forming an airflow away from the wooden board 6. This generates an airflow towards the wooden board 6 on the cutting device, so as to promote the guide wheel 45 to abut against the wooden board 6.

[0059] After the cutting device has been running for a long time, rotating the filter cover 4212 allows both the filter cover 4212 and the filter element 422 to be removed simultaneously from the bottom of the cutting device. After cleaning and discharging the sawdust collected by the filter element 422, the closed end of the filter element 422 is inserted into the lower positioning cylinder 4213. By rotating the filter cover 4212 in the opposite direction, the lower positioning cylinder 4213 secures the filter cover 4212 to the filter housing 4211. Simultaneously, the top of the filter element 422 is fitted over the upper positioning cylinder 4214 and finally secured to the inner top wall of the filter housing 4211. When it is necessary to replace or maintain the filter element 422, unscrew the nut 4216 to remove the filter element 422. Replace the filter element 422 individually or perform other maintenance operations. Then, insert the filter element 422 back onto the filter cover 4212, ensuring its bottom is sealed against the inner wall of the lower positioning cylinder 4213. Finally, tighten the nut 4216 to achieve a sealed and fixed connection between the filter element 422 and the filter cover 4212.

[0060] A further improvement is that the ball joint 51 includes a fixed shell 53 and a ball 54. The fixed shell 53 has a rotating cavity and an opening communicating with the rotating cavity. The ball 54 includes a ball 541 and a locking block 542. The ball 541 has a connected pressing channel 5411 and a locking channel 5412 and its outer surface is in contact with the cavity wall of the rotating cavity. The locking channel 5412 extends to the outer surface of the ball 541. The locking block 542 is slidably connected to the ball 541 through the locking channel 5412. The operating lever 52 includes an operating tube 55 fixedly connected to the ball 541 and communicating directly with the pressing channel 5411, a locking rod 56 connected to the inner wall of the operating tube 55, and a pressing rod 57 slidably connected to the operating tube 55 and extending into the ball 541. The end of the pressing rod 57 away from the locking rod 56 is in contact with the locking block 542 and the contact surface is a plane that has an angle with the sliding direction of the locking block 542 and the axial direction of the pressing rod 57.

[0061] With this structure, the ball joint 51 not only allows for easy adjustment of the angle of the operating lever 52, but also enables convenient locking of the angle position of the operating lever 52. When using this cutting device, the user can flexibly adjust the angle and orientation of the operating lever 52, making the cutting of the wooden board 6 more convenient and flexible.

[0062] Specifically, such as Figures 13-15As shown, the ball joint 51 mainly includes two parts: a fixed shell 53 and a ball 54. The fixed shell 53 is fixed in position relative to the guide frame 41. The ball 54 is rotatably connected to the fixed shell 53, the ball center is fixed in position and fixedly connected to the operating lever 52, so as to facilitate the adjustment of the specific position of the operating lever 52.

[0063] More specifically, the fixed shell 53 includes a lower shell 531 fixed to the bracket 411. The top of the lower shell 531 has a hemispherical recess and is fixedly connected to the upper shell 532 by a third screw 533. The bottom surface of the upper shell 532 is integrally formed with an upper recess and an opening communicating with the upper recess. The curved surface of the inner wall of the upper recess is a spherical surface and coincides with the spherical surface of the upper recess. The central angle of the upper recess is less than 180°. Thus, the lower recess and the upper recess combine to form a rotating cavity. The cavity wall of the rotating cavity, that is, the recess on the top surface of the lower shell 531 and the recess on the bottom surface of the upper shell 532, is in contact with the outer surface of the ball 54.

[0064] The ball bearing 54 consists of two parts: the first part is a sphere 541, and the second part is five locking blocks 542. The sphere 541 has a compression channel 5411 and five locking channels 5412. The compression channel 5411 extends upward from the center of the sphere 541 to the outer surface of the sphere 541. The five locking channels 5412 all extend from the center of the sphere 541 to the outer surface of the sphere 541. One of them extends downward and is coaxial with the compression channel 5411. The other four are arranged in a ring array and extend to the side and downward. The five locking blocks 542 slide in cooperation with the five locking channels 5412.

[0065] The operating lever 52 includes an operating tube 55 integrally connected to the ball 541 and communicating directly with the extrusion channel 5411. An extrusion rod 57 is provided on the inner side of the operating lever 52 and is sealed to its circumferential inner wall. One end of the extrusion rod 57 extends into the ball 541 and is a frustum-shaped quadrangular pyramid. This end is in contact with the side of the five locking blocks 542 near the center of the ball 541. A locking rod 56 is provided at the end of the extrusion rod 57 away from the ball 541 and is threaded to the inner wall of the operating tube 55. One end of the locking rod 56 extends into the operating tube 55 and is fixedly connected to the extrusion rod 57. The other end is integrally connected to a handle 58.

[0066] With the above structure, the locking rod 56 can be easily rotated by the handle 58 to adjust its axial position. When the locking rod 56 approaches the center of the ball 541, it abuts against the pressing rod 57, causing the pressing rod 57 to tend to move towards the center of the ball 541. This causes the end of the pressing rod 57 away from the locking rod 56 to apply pressure to the locking block 542, causing the locking block 542 to slide along the locking channel 5412 and abut against the cavity wall of the rotating cavity. This increases the pressure and friction between the locking block 542 and the fixed shell 53, thereby fixing the angle of the ball 541 and the operating rod 52. When the locking rod 56 moves away from the center of the ball 541, the pressure between the locking rod 56 and the pressing rod 57 decreases, thereby reducing the compressive force on the locking block 542 and the compressive force between the locking block 542 and the fixed shell 53. This allows the ball 54 to rotate easily and the angle of the operating rod 52 to be adjusted.

[0067] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
