Description

Technical Field

[0001] This application relates to the field of wood furniture processing, and in particular to a panel saw with automatic edge-changing cutting. Background Technology

[0002] With the rise of panel furniture, the related woodworking machinery has also developed rapidly. To produce exquisite panel furniture, a panel saw with high precision, high stability, and high straightness is required, and the straight-line worktable of the panel saw is the key to ensuring the straightness of the processing.

[0003] Precision panel saws (or sliding table saws) can be used for longitudinal and transverse cutting of various engineered wood products such as veneered particleboard, fiberboard, plywood, solid wood boards, plastic boards, aluminum alloys, etc. They are widely used in the panel furniture industry and wood processing industries such as vehicle and ship manufacturing, and are considered general-purpose equipment in woodworking machinery.

[0004] The existing panel saws use fixed-size workbenches to support the wooden boards. When trimming the edges of the boards, manual replacement of the boards is required. When the boards are large, each panel saw requires at least two workers to work simultaneously, which is not only inefficient but also physically demanding. Summary of the Invention

[0005] In order to replace the traditional manual process of changing the shape of the wooden board, improve the efficiency of cutting the edge of the board, and reduce the labor intensity of the workers, this application provides an automatic edge-changing cutting panel saw.

[0006] The automatic edge-changing cutting panel saw provided in this application adopts the following technical solution:

[0007] An automatic edge-changing panel saw includes a frame with a saw wheel mounted on it. A worktable is slidably connected to one side of the frame. The worktable includes a support plate and a load-bearing plate rotatably connected to the top of the support plate. A sliding groove is provided at the bottom of the support plate, and a drive box is connected to the bottom of the support plate. A drive assembly is provided inside the drive box. The drive assembly passes through the sliding groove and is connected to the load-bearing plate. The drive assembly is used to drive the load-bearing plate to rotate 90 degrees intermittently in a cyclical manner to achieve edge changing of the wood board.

[0008] By adopting the above technical solution, the drive component drives the support plate to rotate 90 degrees sequentially on top of the support plate, which can orderly rotate the sides of the wooden board on the support plate to the position of the saw wheel, so that the saw wheel can cut the four sides of the wooden board, replacing the traditional manual turning of the wooden board, improving the efficiency of cutting the wooden board, and reducing the labor intensity of the workers.

[0009] Optionally, a positioning cylinder is fixedly connected to the top of the drive box, and the middle of the positioning cylinder is hollow. The drive assembly includes a dial rotatably connected to the drive box, a drive motor fixedly connected to the outer wall of the drive box, the output shaft of the drive motor extending into the drive box and fixedly connected to the dial, a fixed plate fixedly connected to the dial, an arc-shaped notch groove on the fixed plate, the two ends of the notch groove forming a 90-degree right angle with the center of the fixed plate, forming an outwardly concave locking arc on the dial, and a round pin fixedly connected to the top of the dial, the round pin being located in the notch groove of the positioning plate; a grooved wheel is rotatably connected inside the drive box, the grooved wheel having four radial grooves, two adjacent radial grooves forming a 90-degree right angle with the center of the grooved wheel, and an inwardly concave locking arc between two adjacent radial grooves, the radial grooves being used for the round pin to be inserted, a drive shaft fixedly connected to the middle of the grooved wheel, the drive shaft rotatably connected to the positioning cylinder, the drive shaft extending out of the positioning cylinder and fixedly connected to the bottom of the support plate.

[0010] By employing the above technical solution, the drive motor rotates. When the pin on the dial is not yet in the radial groove of the grooved wheel, the grooved wheel remains stationary because its inner locking arc is locked by the outer locking arc of the dial. As soon as the pin enters the radial groove, the grooved wheel rotates under its drive. When the pin leaves the radial groove on the other side, the locking arc is locked again, and the grooved wheel remains stationary. This process repeats until the pin enters another radial groove of the grooved wheel. This achieves intermittent 90-degree movement of the grooved wheel, which in turn drives the bearing plate to rotate intermittently by 90 degrees via the drive shaft on the grooved wheel. This sequentially rotates the four sides of the wooden board to one side of the saw wheel, thus automatically cutting the four sides of the wooden board.

[0011] Optionally, a guide frame is fixedly connected to the bottom of the support plate, a guide block is slidably connected inside the guide frame, the bottom of the guide block is fixedly connected to the top of the drive box, a pusher cylinder is hinged to the bottom of the support plate, the cylinder body of the pusher cylinder is hinged to the support plate, and the piston rod end of the pusher cylinder is hinged to the guide block.

[0012] By adopting the above technical solution, before the bearing plate rotates, the piston rod of the pushing cylinder extends, pushing the guide block to slide away from the frame in the guide frame. The guide block drives the drive box to slide away from the frame. The guide frame guides and positions the drive, thereby driving the bearing plate to slide outward, thus reserving space for the bearing plate and the wooden board to rotate without interfering with the frame.

[0013] Optionally, a vacuum chamber is provided inside the support plate, and multiple vacuum holes are provided on the top of the support plate. The vacuum holes are connected to the vacuum chamber. A vacuum pump is fixedly connected to the bottom of the support plate, and an exhaust pipe is fixedly connected to the vacuum pump. The exhaust pipe passes through the drive shaft and is connected to the vacuum chamber.

[0014] By adopting the above technical solution, the vacuum pump works, and the exhaust pipe evacuates the vacuum chamber, adsorbing the wooden board onto the top of the support plate, thereby preventing the wooden board from falling off as it rotates with the support plate.

[0015] Optionally, a pressing mechanism is provided on the frame; a slide rail is provided on the side of the frame away from the guide rail, and the pressing mechanism includes a sliding frame that is slidably connected to the slide rail. The bottom of the sliding frame is fixed to the bottom of the support plate, and the top of the sliding frame extends above the bearing plate. A pressing cylinder is provided on the sliding frame, and the pressing cylinder is vertically downward. A pressing plate is fixedly connected to the end of the piston rod of the pressing cylinder.

[0016] By adopting the above technical solution, during the cutting of the wooden board, the piston rod of the pressure cylinder extends, pushing the pressure plate downward and abutting against the wooden board to fix the wooden board, preventing the wooden board from moving during the cutting process, making the cutting of the wooden board more standard and reducing the scrap rate; the bottom of the sliding frame and the support plate are fixed so that the sliding frame and the support plate slide synchronously.

[0017] Optionally, a telescopic plate is slidably connected to the top of the sliding frame, and a pressing cylinder is fixedly connected to the end of the telescopic plate away from the sliding frame.

[0018] By adopting the above technical solution, the position of the telescopic plate can be adjusted to make the pressure plate press against the middle of the wooden board, thus fixing the wooden board more stably.

[0019] Optionally, the bottom of the support plate is connected to a support mechanism; the support mechanism includes a telescopic sleeve with one end hinged to the frame, a support rod provided at the end of the telescopic sleeve away from the frame, the support rod being vertically arranged and fixedly connected to the bottom of the support plate.

[0020] By adopting the above technical solution, since one side of the support plate is slidably connected to the frame, most of the support plate is suspended in the air. The support rod can support the support plate and share the pressure between the support plate and the frame, thereby extending the service life of the support plate and the bracket.

[0021] Optionally, a movable plate is slidably connected inside the telescopic sleeve, and a support rod is located at the end of the movable plate away from the telescopic sleeve. The end of the telescopic sleeve away from the support rod is open to facilitate the sliding of the movable plate and its extension out of the telescopic sleeve.

[0022] By adopting the above technical solution, the movable plate slides within the telescopic sleeve, ensuring that the support rod always abuts against and supports the bottom of the support plate during the sliding process along the frame, thus ensuring that it can play a load-bearing role.

[0023] Optionally, a guide rail is fixedly connected to the frame, and a T-shaped groove is provided in the guide rail. A T-shaped slider is fixedly connected to one side of the support plate, and the T-shaped slider is slidably connected to the T-shaped groove of the guide rail.

[0024] By adopting the above technical solution, during the cutting process, the support plate slides along the guide rail of the frame, and the T-shaped slider slides in the T-shaped groove of the guide rail, which plays a guiding and positioning role for the support plate, making the sliding of the support plate more stable.

Detailed Implementation

[0032] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0033] This application discloses an automatic edge-changing panel saw. (See also...) Figure 1 An automatic edge-changing cutting panel saw includes a frame 1, a relief groove 11 on the frame 1, a saw wheel 12 on the frame 1, the saw wheel 12 protruding through the relief groove 11 and protruding from the top of the worktable 2, and the worktable 2 is slidably connected to one side of the frame 1 for supporting the wooden board.

[0034] Reference Figure 1 and Figure 2 The workbench 2 includes a support plate 21 and a bearing plate 22 rotatably connected to the top of the support plate 21. A T-shaped slider 211 is fixedly connected to one side of the support plate 21. A guide rail 13 is fixedly connected to the frame 1. A T-shaped groove 131 is provided in the guide rail 13. The T-shaped slider 211 is slidably connected to the T-shaped groove 131 of the guide rail 13.

[0035] Reference Figure 3 Since the wooden boards are mostly rectangular, to prevent interference between the wooden boards and the frame 1 during the rotation of the support plate 22, a guide frame 25 is fixedly connected to the bottom of the support plate 21. A guide block 251 is slidably connected inside the guide frame 25, and a drive box 24 is fixedly connected to the bottom of the guide block 251. The drive box 24 is connected to the bottom of the support plate 22 and is used to drive the support plate 22 to rotate. A pusher cylinder 26 is hinged to the bottom of the support plate 21. The cylinder body of the pusher cylinder 26 is hinged to the support plate 21, and the piston rod end of the pusher cylinder 26 is hinged to the guide block 251. Before the support plate 22 rotates, the piston rod of the pusher cylinder 26 extends, pushing the guide block 251 to slide away from the frame 1 inside the guide frame 25. The guide block 251 drives the drive box 24 to slide away from the frame 1, thereby driving the support plate 22 to slide outward, thus reserving space for the support plate 22 and the wooden boards to rotate and preventing interference with the frame 1.

[0036] Reference Figure 3 and Figure 4 The bottom of the support plate 21 is provided with a sliding groove 212, which is parallel to the guide frame 25. The sliding groove 212 is arranged along the diagonal of the support plate 21. The top of the drive box 24 is fixedly connected to a positioning cylinder 23, which is hollow in the middle. A dial 242 is rotatably connected inside the drive box 24. A drive motor 241 is fixedly connected to the outer wall of the drive box 24. The output shaft of the drive motor 241 extends into the drive box 24 and is fixedly connected to the dial 242. A fixed plate 243 is fixedly connected to the dial 242. An arc-shaped notch 244 is provided on the fixed plate 243. The two ends of the notch 244 form a 90-degree right angle with the center of the fixed plate 243, so that the dial 242 forms an outward concave shape. A locking arc is formed by a pin 245 fixedly connected to the upper part of the dial 242, which is located in the notch 244 of the positioning plate. A grooved wheel 246 is rotatably connected inside the drive box 24. The grooved wheel 246 has four radial grooves 247. Two adjacent radial grooves 247 form a 90-degree right angle with the center of the grooved wheel 246. An inward locking arc is formed between two adjacent radial grooves 247. The radial grooves 247 are used for the insertion of the pin 245. A drive shaft 248 is fixedly connected to the middle of the grooved wheel 246. The drive shaft 248 is hollow and passes through the positioning cylinder 23 and can rotate inside the positioning cylinder 23. The drive shaft 248 extends out of the positioning cylinder 23 and is fixedly connected to the bottom of the support plate 22.

[0037] When the drive motor 241 rotates, if the pin 245 on the dial 242 has not entered the radial groove 247 of the grooved wheel 246, the grooved wheel 246 remains stationary because its inner locking arc is locked by the outer locking arc of the dial 242. As soon as the pin 245 enters the radial groove 247, the grooved wheel 246 rotates under the drive of the pin 245. When the pin 245 leaves the radial groove 247 on the other side, the locking arc is locked again, and the grooved wheel 246 remains stationary. This process repeats until the pin 245 enters the other radial groove 247 of the grooved wheel 246. This achieves intermittent 90-degree movement of the grooved wheel 246, which in turn drives the bearing plate 22 to rotate intermittently by 90 degrees via the drive shaft 248 on the grooved wheel 246. This sequentially rotates the four sides of the wooden board to one side of the saw wheel 12, thus automatically cutting the four sides of the wooden board.

[0038] Reference Figure 5 and Figure 6 To prevent the wooden board from falling off the support plate 22 during rotation, a vacuum chamber 221 is provided inside the support plate 22. Multiple vacuum holes 222 are located on the top of the support plate 22, communicating with the vacuum chamber 221. The vacuum holes 222 are funnel-shaped. A vacuum pump 223 is fixedly connected to the bottom of the support plate 21, and an exhaust pipe 224 is fixedly connected to the vacuum pump 223. The exhaust pipe 224 extends into the drive shaft 248, passes through the drive shaft 248, and communicates with the vacuum chamber 221. When the vacuum pump 223 operates, the exhaust pipe 224 evacuates the vacuum chamber 221, adsorbing the wooden board onto the top of the support plate 22, thus preventing the wooden board from falling off as the support plate 22 rotates.

[0039] Reference Figure 1 and Figure 2 To prevent the wood board from shaking due to friction between the wood board and the saw wheel 12 during the cutting process, a pressing mechanism 3 is provided on the frame 1. A slide rail 14 is provided on the side of the frame 1 away from the guide rail 13. The pressing mechanism 3 includes a sliding frame 31 that is slidably connected to the slide rail 14. The bottom of the sliding frame 31 is fixed to the bottom of the support plate 21, and the top of the sliding frame 31 extends above the bearing plate 22. A telescopic plate 32 is slidably connected to the top of the sliding frame 31, and a pressing cylinder 33 is fixedly connected to the telescopic plate 32. The pressing cylinder 33 is set vertically downwards, and the cylinder body of the pressing cylinder 33 is fixedly connected to the sliding frame 31. The piston rod end of the pressing cylinder 33 is fixedly connected to the pressure plate 34. During the cutting of the wooden board, the piston rod of the pressing cylinder 33 extends, pushing the pressure plate 34 to move downwards and abut against the wooden board to fix the wooden board and prevent the wooden board from moving during the cutting process. The telescopic plate 32 can adjust the position of the pressing cylinder 33 so that the pressure plate 34 is pressed against the middle position of the wooden board, making the wooden board more stable.

[0040] Reference Figure 1 and Figure 2 The bottom of the support plate 21 is connected to the support mechanism 4. The support mechanism 4 includes a telescopic sleeve 41 hinged to the frame 1. A movable plate 42 is slidably connected inside the telescopic sleeve 41. A support rod 43 is fixedly connected to the end of the movable plate 42 that is slid away from the telescopic sleeve 41. The support rod 43 is vertically arranged and fixedly connected to the bottom of the support plate 21. The end of the telescopic sleeve 41 that is away from the support rod 43 is open, which facilitates the sliding of the movable plate 42 and its extension out of the telescopic sleeve 41. Since one side of the support plate 21 is slidably connected to the guide rail 13, most of the support plate 21 is suspended. The support rod 43 can support the support plate 21 and share the pressure between the support plate 21 and the guide rail 13, thereby extending the service life of the support plate 21 and the guide rail 13. The movable plate 42 slides inside the telescopic sleeve 41, which can ensure that the support rod 43 always abuts against and supports the bottom of the support plate 21 during the sliding process of the support plate 21 along the guide rail 13, ensuring that it can play a load-bearing role.

[0041] The implementation principle of an automatic edge-changing cutting panel saw according to an embodiment of this application is as follows: When cutting the four sides of a wooden board, the wooden board is first placed on the support plate 22, the support plate 21 slides along the guide rail 13, and the saw wheel 12 cuts one side of the template; then, when it is necessary to cut the other side, the piston rod of the pressure cylinder 33 retracts, the vacuum pump 223 works, the exhaust pipe 224 evacuates the vacuum chamber 221, and the wooden board is adsorbed onto the top of the support plate 22. Then, the drive motor 241 rotates, and as soon as the round pin 245 enters the radial groove 247 of the grooved wheel 246, the grooved wheel 246 rotates under the drive of the round pin 245. When the round pin 245 leaves the radial groove 247 on the other side, the locking arc is locked again, and the grooved wheel 246 remains stationary until the round pin 245 enters the other radial groove 247 of the grooved wheel 246 again, and the above movement is repeated. This achieves the intermittent movement of the grooved wheel 246 at ninety degrees, which in turn drives the bearing plate 22 to rotate intermittently at ninety degrees through the transmission shaft 248 on the grooved wheel 246. This allows the four sides of the wooden board to be rotated to one side of the saw wheel 12 in sequence, thereby automatically cutting the four sides of the wooden board, replacing the traditional manual edge turning, improving processing efficiency and reducing labor.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
