Description

Technical Field

[0001] This utility model belongs to the technical field of wood processing equipment, specifically a wood processing push table saw. Background Technology

[0002] A sliding table saw, also known as a precision panel saw, is suitable for processing materials such as plywood, particleboard, fiberboard, solid wood boards, plastic boards, and aluminum alloys. It is a key piece of equipment in industries such as panel furniture and construction decoration. During processing, the board is placed on the worktable, and when the board is pushed into contact with the saw blade, the high-speed rotation of the saw blade completes the cutting of the board.

[0003] However, when the board comes into contact with the saw blade, it will be subjected to the reaction force of the saw blade. The operator manually holds the board and push plate tightly. In order to counteract the reaction force of the saw blade, the operator may subconsciously exert force to deviate, which will cause the board to tilt and the cutting line to deviate from the preset trajectory. This can easily lead to problems such as beveled edges and chipped edges, affecting the processing accuracy.

[0004] Therefore, it is necessary to design a sliding table saw that can ensure machining accuracy. Summary of the Invention

[0005] Based on this, this solution provides a sliding table saw for wood processing. The electric push rod built into the push plate drives the baffle to slide, so that the baffle can quickly limit the board of different widths. When pushing, the board is subjected to uniform force, which can avoid cutting deviation due to skew.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0007] A sliding table saw for wood processing includes a frame on which a cutting mechanism is rotatably mounted. A support plate and a pushing mechanism are fixed to the top of the frame. The pushing mechanism includes a support rod and a locking rod. Two support rods are fixedly connected to the top of the frame, and a locking rod is fixedly mounted on the top of each support rod. A locking plate is slidably mounted on the locking rod, and a connecting block is fixedly mounted on one end of each locking plate. A push plate is fixedly mounted between the two locking plates, and an electric push rod is fixedly mounted inside the push plate. A baffle is fixedly connected to the telescopic end of the electric push rod, and the baffle is slidably connected to the push plate. An abutment mechanism is slidably mounted on the support plate.

[0008] Optionally, in one embodiment of the present invention, the pushing mechanism further includes ball bearings, and a plurality of ball bearings are rotatably mounted at equal intervals inside the card plate, and the ball bearings are in rolling connection with the card rod.

[0009] Optionally, in one embodiment of the present invention, the inner wall of the card plate near the card rod is arranged in an arc-shaped structure, the length of the card plate is less than the length of the push plate, and the connecting block is arranged in an L-shaped structure.

[0010] Optionally, in one embodiment of the present invention, the height of the push plate near the card plate is greater than the height of the push plate away from the card plate, and the length of the push plate is less than the length of the support rod and the card rod.

[0011] Optionally, in one embodiment of the present invention, the cutting mechanism includes a hydraulic rod and a protective cover. The hydraulic rod is fixedly installed at the top of the frame, and the protective cover is fixedly connected to the telescopic end of the hydraulic rod. A saw blade is rotatably installed on the frame, and the protective cover is located on top of the saw blade.

[0012] Optionally, in one embodiment of the present invention, the abutment mechanism includes a fixed frame and support blocks. Two support blocks are symmetrically fixedly installed at the bottom end of the support plate. A fixed frame is fixedly connected between the two support blocks. A lead screw is rotatably installed inside the fixed frame. A handwheel is fixedly connected to the lead screw. A slide rod is threadedly connected to the lead screw. An abutment plate is fixedly connected to the slide rod.

[0013] Optionally, in one embodiment of the present invention, the slide rod is arranged in an L-shape, and the slide rod is slidably connected to the support plate and the fixing frame, and the abutment plate is slidably connected to the support plate.

[0017] The sliding cooperation between the clamping plate and the clamping rod ensures that the plate is evenly stressed during pushing, preventing cutting deviation caused by the tilt of the push plate. The electric push rod built into the push plate can drive the baffle to slide, enabling quick positioning of plates of different widths. It can adapt to diverse processing needs without changing parts, improving efficiency. The sliding connection design between the baffle and the push plate ensures that it always fits the side of the plate during pushing, preventing the operator's hands from getting close to the cutting saw blade area.

Therefore, the terms describing positional relationships in the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances. Example

[0028] Because existing sliding table saws require operators to manually hold the board tightly against the push plate, they may subconsciously shift their grip to counteract the saw blade's reaction force, causing the board to tilt and the cutting line to deviate from the preset trajectory, which can easily lead to problems. Therefore, a woodworking sliding table saw designed to avoid cutting deviation was developed, and the specific solution is as follows:

[0029] like Figure 1-6 As shown, a woodworking table saw includes a frame 1, on which a cutting mechanism 4 is rotatably mounted. A support plate 2 and a pushing mechanism 5 are fixed to the top of the frame 1. The pushing mechanism 5 includes a support rod 501 and a locking rod 502. Two support rods 501 are fixedly connected to the top of the frame 1, and a locking rod 502 is fixedly mounted on the top of each support rod 501. A locking plate 506 is slidably mounted on the locking rod 502. The inner wall of the locking plate 506 near the locking rod 502 has an arc-shaped structure. The length of the locking plate 506 is... The length of the clamping plate 506 is less than that of the push plate 503. A connecting block 507 is fixedly installed at one end of the clamping plate 506. The connecting block 507 is L-shaped. Several ball bearings 508 are equidistantly mounted inside the clamping plate 506. The ball bearings 508 are rolled and connected to the clamping rod 502. By gripping both sides of the push plate 503, the push plate 503 is pushed towards the saw blade 403. Two clamping plates 506 are symmetrically fixed at the bottom of the push plate 503. Ball bearings 508 are rotatably mounted inside the clamping plates 506. Moving along the locking rod 502, the ball bearing 508 contacts the surface of the locking rod 502. The rotation of the ball bearing 508 reduces the resistance generated by the sliding of the locking plate 506, allowing the push plate 503 to move the plate towards the saw blade 403 at a uniform speed. A push plate 503 is fixedly installed between the two locking plates 506. The height of the end of the push plate 503 closer to the locking plate 506 is greater than the height of the end of the push plate 503 away from the locking plate 506. The length of the push plate 503 is less than the length of the support rod 501 and the locking rod 502. An electric push rod 505 is fixedly installed inside the push plate 503. A baffle 504 is fixedly connected to the telescopic end of the electric push rod 505. The baffle 504 is slidably connected to the push plate 503. When the electric push rod 505 installed inside the push plate 503 is activated, the electric push rod 505 pushes the baffle 504 fixed at the telescopic end to slide along the push plate 503 until the baffle 504 is in contact with the other side of the plate. This can limit the width of the plate and prevent it from sliding during pushing. An abutment mechanism 3 is slidably installed on the support plate 2.

[0030] The cutting mechanism 4 includes a hydraulic rod 401 and a protective cover 402. The hydraulic rod 401 is fixedly installed at the top of the frame 1, and the protective cover 402 is fixedly connected to the telescopic end of the hydraulic rod 401. A saw blade 403 is rotatably installed on the frame 1. When the board comes into contact with the saw blade 403, the motor is started, causing its output shaft to drive the large guide wheel to rotate. Since a belt is wound between the large guide wheel and the small guide wheel, the belt drives the small guide wheel to rotate, which can drive the shaft to drive the saw blade 403 to rotate. Thus, when the board completely passes through the saw blade 403, the cutting can be completed. The protective cover 402 is located on top of the saw blade 403. The protective cover 402 rises and falls with the hydraulic rod 401, which can prevent sawdust from flying and also prevent the operator from accidentally touching the saw blade 403.

[0031] The contact mechanism 3 includes a fixed frame 301 and support blocks 306. Two support blocks 306 are symmetrically fixedly installed on the bottom end of the support plate 2. The support blocks 306 are located at the end of the support plate 2 away from the hydraulic rod 401. The fixed frame 301 is fixedly connected between the two support blocks 306. A lead screw 305 is rotatably installed inside the fixed frame 301. A handwheel 302 is fixedly connected to the lead screw 305. The handwheel 302 is located at the end of the fixed frame 301 away from the saw blade 403. A sliding rod 303 is threadedly connected to the lead screw 305. The sliding rod 303 is arranged in an L-shape and is connected to the support plate 2. The fixed frame 301 is slidably connected to the slide rod 303, and the abutment 304 is fixedly connected to the slide rod 303. The height of the slide rod 303 is lower than the height of the abutment 304. The handwheel 302 is rotated to drive the screw 305 installed in the fixed frame 301 to rotate. The fixed frame 301 is fixedly connected to the support block 306 installed at the bottom of the support plate 2. The slide rod 303 is threadedly connected to the screw 305. Under the limiting action of the fixed frame 301, the slide rod 303 moves the abutment 304 towards the side of the plate. The height of the baffle 504 is lower than the height of the push plate 503 near the handwheel 302.

[0032] Working principle:

[0033] First, place the sheet material flat on the support plate 2, aligning one edge with the cutting baseline. Then, turn the handwheel 302 to drive the lead screw 305 inside the fixing frame 301 to rotate. The fixing frame 301 is fixedly connected to the support block 306 at the bottom of the support plate 2. A sliding rod 303 is threaded onto the lead screw 305. Under the limiting action of the fixing frame 301, the sliding rod 303 moves the abutment plate 304 towards the side of the sheet material until the abutment plate 304 is in close contact with the side of the sheet material, thus completing the lateral dimension positioning and fixing of the cutting width. Then, through the electric push rod 505 inside the push plate 503, push the baffle 504 to slide along the push plate 503 until the baffle 504 is in contact with the other side of the sheet material, which can limit the width of the sheet material and prevent it from sliding during pushing. The baffle 504 and the abutment plate 304 provide double limiting to avoid the risk of collision or rebound caused by the sliding of the sheet material.

[0034] During cutting, hold both sides of the push plate 503 with both hands and push the push plate 503 towards the saw blade 403. The clamping plate 506 moves along the clamping rod 502, so that the ball bearing 508 contacts the surface of the clamping rod 502. The ball bearing 508 rotates, reducing the sliding resistance of the clamping plate 506, so that the push plate 503 drives the plate to move towards the saw blade 403 at a uniform speed. When the plate contacts the saw blade 403, start the motor to drive the large guide wheel to rotate, so that the shaft drives the saw blade 403 to rotate, and the cutting is completed when the plate has completely passed through the saw blade 403.

[0035] The protective cover 402 rises and falls with the hydraulic rod 401, which can prevent sawdust from flying and also prevent the operator from accidentally touching the saw blade 403. After cutting, the push plate 503 is pulled back to the initial position, and the electric push rod 505 drives the baffle 504 to reset, so that the cut board can be removed.

[0036] The sliding table saw of this design has a ball bearing 508 in the chuck plate 506 that is in rolling contact with the chuck rod 502. This reduces the resistance of the pushing mechanism when it moves, allowing the operator to push the push plate and the board more easily and smoothly, so as to achieve uniform speed approach to the saw blade 403. This greatly improves the cutting accuracy and cut quality, and reduces the cutting deviation caused by uneven resistance.

[0037] The baffle 504 is driven to slide by the electric push rod 505, which can quickly and accurately fit one side of the board and realize reliable limiting of the pushing direction, effectively preventing the board from sliding back and forth during the pushing process; the abutment is driven to move by the lead screw 305 and the slide rod 303, which can firmly abut against the side of the board and accurately fix the cutting width.

[0038] The baffle 504 and the stop plate 304 form a double limit, fixing the plate in the processing position, eliminating the risk of slippage, displacement or rebound of the plate during pushing and cutting, and improving operational safety and processing accuracy.

[0039] The top of the saw blade 403 is equipped with a protective cover 402 that can be raised and lowered with the hydraulic rod to block the flying sawdust generated during cutting, improve the working environment, and protect the operator. It can be raised when not cutting or during adjustment so as not to obstruct the placement and observation of the board, and can be lowered to provide protection during cutting. Example

[0040] In this embodiment, the structure of the sliding table saw is basically the same as that of Embodiment 1, except that a dust suction port is provided inside the frame 1 below the saw blade 403, and the dust suction port is connected to an external dust collection device. A dust suction port is also provided inside the protective cover 402 near the saw blade 403, which improves the working environment and protects the equipment components. Example

[0041] In this embodiment, the structure of the sliding table saw is basically the same as that of Embodiment 1. The difference is that the front end and both sides of the protective cover 402 are designed with a transparent structure, so that the operator can observe the contact point between the saw blade 403 and the board and the cutting status during the cutting process, thereby improving the safety and controllability of the operation.

[0042] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
