Description

Technical Field

[0001] This application relates to the technical field of material cutting, and in particular to a sliding table saw. Background Technology

[0002] An existing table saw for cutting wood mainly includes a worktable, a motor bracket, a worktable support, a motor, and a circular saw. The motor is mounted on the motor bracket, which is in turn mounted on the worktable support. The circular saw is mounted on the motor's drive shaft, and the worktable is positioned above the worktable support. During operation, the motor drives the circular saw to rotate at high speed. The operator manually pushes the wood planks on the worktable, and the rotating circular saw cuts the wood planks.

[0003] During operation, because cutting wooden boards requires the operator to push the boards on the workbench by hand, the operator's hand is close to the high-speed rotating circular saw, which easily leads to safety accidents such as hand injuries from the circular saw. This needs to be improved. Utility Model Content

[0004] The purpose of this application is to provide a sliding table saw to prevent hand injuries from circular sawing.

[0005] The sliding table saw provided in this application adopts the following technical solution: it includes a cutting table, a circular saw rotatably connected to the cutting table, a first driving member connected to the cutting table for driving the circular saw to rotate, a carrier plate slidably connected to the cutting table, a lifting assembly connected to the cutting table for driving the carrier plate to rise and fall, a plurality of pressure rollers rotatably connected to the carrier plate, and a linkage assembly connected to the carrier plate for driving all the pressure rollers to rotate.

[0006] By adopting the above technical solution, the wooden board is placed on the cutting table and located below the lifting component. The lifting component drives the carrier plate to descend, and the pressure roller moves with the carrier plate until the pressure roller contacts the wooden board. The linkage component drives all pressure rollers to rotate. During the rotation, the pressure rollers drive the wooden board to move towards the circular saw, thereby completing the cutting of the wooden board. This avoids the operator pushing the wooden board by hand, prevents the circular saw from injuring their hands, and improves operational safety.

[0007] Optionally, the linkage assembly includes a linkage rod rotatably connected to the carrier plate and a second driving member connected to the carrier plate. The second driving member is used to drive the linkage rod to rotate. One end of each pressure roller is fixedly connected to a passive bevel gear, and the linkage rod is fixedly connected to an active bevel gear that corresponds one-to-one with the passive bevel gear. The active bevel gear meshes with the passive bevel gear.

[0008] By adopting the above technical solution, the second driving component drives the linkage rod to rotate around its own axis, and all the active bevel gears rotate around the axis of the linkage rod. During the rotation of the active bevel gears, the passive bevel gears are driven to rotate, thereby causing the pressure rollers to rotate around their own axes. The rotation of all the pressure rollers is connected through the second driving component, linkage rod, active bevel gears and passive bevel gears, reducing the driving force and increasing the overall structural coherence.

[0009] Optionally, each of the pressure rollers has an elastic ring attached to its outer circumferential surface.

[0010] By adopting the above technical solution, the elastic ring can reduce the damage to the wooden board caused by the pressure roller when moving the board, thereby improving the cutting quality of the board. When the elastic ring comes into contact with the wooden board, the elastic ring is compressed and undergoes elastic deformation, maintaining a tendency to elastically return to its original position. The elastic ring applies force to the wooden board, increasing the pressure on the board and facilitating the movement of the board by the elastic ring.

[0011] Optionally, the outer circumferential surface of the pressure roller is detachably connected to an mounting ring, the elastic ring is fixedly connected to the outer circumferential surface of the mounting ring, and the pressure roller is connected to a fixing component for fixing the mounting ring to the pressure roller.

[0012] By adopting the above technical solution, when the elastic ring is damaged after long-term use, the fixing component can loosen the mounting ring and remove the mounting ring from the pressure roller, which can avoid the elastic ring being directly connected to the pressure roller and difficult to disassemble, and facilitate the replacement and maintenance of the elastic ring.

[0013] Optionally, the fixing component includes a positioning part connected to the pressure roller and a fixing block threadedly connected to the pressure roller. The positioning part is located between the driven bevel gear and the mounting ring, and the mounting ring is located between the positioning part and the fixing block. The fixing block is used to abut against the mounting ring.

[0014] By adopting the above technical solution, when installing the mounting ring, the mounting ring is sleeved on the pressure roller until it abuts against the positioning part. The positioning part plays a positioning role in the installation of the mounting ring, so that the mounting ring is accurately installed in the corresponding position. Rotate the fixing block until it abuts against the mounting ring. The mounting ring is clamped by the fixing block and the positioning part, thereby fixing the mounting ring on the pressure roller.

[0015] Optionally, the mounting ring is connected to a stop part, and the pressure roller is provided with a stop groove, which is used to cooperate with the stop part.

[0016] By adopting the above technical solution, when installing the mounting ring, the stop part engages with the stop groove, and the mounting ring moves along the length of the pressure roller. The sliding fit between the stop part and the stop groove guides and limits the movement of the mounting ring, thereby improving the stability of the mounting ring's movement and thus increasing the installation efficiency. When the pressure roller rotates, the inner wall of the stop groove abuts against the stop part and drives the mounting ring to rotate, further driving the mounting ring to rotate around the axis of the pressure roller.

[0017] Optionally, the number of the stop portion and the number of the stop groove are both two, with the two stop portions distributed opposite each other, and the stop grooves corresponding one-to-one with the stop portions.

[0018] By adopting the above technical solution, the two relatively distributed stop parts are matched one-to-one with the two stop grooves on the pressure roller, which can prevent the mounting ring from rotating relative to the pressure roller during the rotation process, ensure the stability of the contact between the elastic ring and the wood board, and facilitate the conveying and cutting of the wood board.

[0019] Optionally, the pressure roller is slidably connected to a reset plate, and the pressure roller is connected to a reset component. The reset component is used to drive the reset plate to reset, and the reset plate is located between the mounting ring and the positioning part.

[0020] By adopting the above technical solution, when installing the mounting ring, the mounting ring abuts against the reset plate and drives the reset plate to slide closer to the elastic element. The elastic element is compressed, generates elastic deformation, and maintains an elastic reset tendency. When disassembling the mounting ring, the fixing block is released, the elastic element elastically resets, and the elastic element forces the reset plate to slide closer to the mounting ring. The reset plate abuts against the mounting ring and drives one end of the mounting ring to protrude from the pressure roller, thereby improving the disassembly efficiency of the mounting ring.

[0021] Optionally, the positioning part is provided with an annular groove, and the reset member is installed in the annular groove.

[0022] By adopting the above technical solution, when installing the mounting ring, the mounting ring abuts against the reset plate and drives the reset plate to slide towards the elastic element until the reset plate moves to the positioning part and abuts against it. Tightening the fixing block prevents the mounting ring from moving along the length direction of the pressure roller during the process of the elastic ring abutting against the wooden board, thereby improving the stability of the mounting ring installed on the pressure roller.

[0023] Optionally, the cutting table is connected to a positioning strip, which is used to abut against the wooden board and is located between the cutting table and the pressure roller.

[0024] By adopting the above technical solution, the wooden board is placed on the cutting table, and one side of the wooden board abuts against the positioning strip, so that the wooden board is accurately installed in the corresponding position, which facilitates the elastic ring to abut against the wooden board and drive the wooden board to move.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. Place the wooden board on the cutting table and below the lifting assembly. The lifting assembly lowers the board, and the pressure roller moves with the board until it contacts the board. The linkage assembly then drives all the pressure rollers to rotate. As the rollers rotate, they move the board closer to the circular saw, thus completing the cutting of the board. This avoids the operator pushing the board by hand, prevents injury from the circular saw, and improves operational safety.

[0026] 2. The second driving component drives the linkage rod to rotate around its own axis. All the active bevel gears rotate around the axis of the linkage rod. During the rotation of the active bevel gears, the passive bevel gears are driven to rotate, thereby causing the pressure rollers to rotate around their own axes. The rotation of all the pressure rollers is connected through the second driving component, linkage rod, active bevel gears and passive bevel gears, reducing the driving force and increasing the overall structural coherence.

When the wooden board is installed on the cutting table 1, one side of the wooden board is in contact with the positioning strip 14, and the positioning strip 14 is located between the side of the wooden board away from the cutting table 1 and the cutting table 1.

[0038] Combination Figure 3 and Figure 4 As shown, a number of pressure rollers 4 are rotatably connected to the side of the carrier plate 2 near the cutting table 1. All pressure rollers 4 are spaced apart, and the distance between two adjacent pressure rollers 4 is equal. The carrier plate 2 is connected to a linkage assembly 5, which drives all pressure rollers 4 to rotate in the same direction. The linkage assembly 5 includes a linkage rod 51 rotatably connected to the carrier plate 2 and a second drive component 52 fixedly connected to the carrier plate 2. The second drive component 52 is a motor. The signal output terminal of the controller is connected to the signal input terminal of the second drive component 52. The end of the linkage rod 51 near the second drive component 52 is fixedly connected to the output terminal of the second drive component 52. The linkage rod 51 rotates around its own axis through the second drive component 52. A passive bevel gear 41 is fixedly connected to one end of each pressure roller 4. An active bevel gear 511 corresponding to the passive bevel gear 41 is fixedly connected to the outer circumferential surface of the linkage rod 51. The active bevel gear 511 meshes with the passive bevel gear 41.

[0039] Combination Figure 3 , Figure 4 , Figure 5and Figure 6 As shown, each pressure roller 4 has an mounting ring 6 fitted on its outer circumferential surface. The mounting ring 6 is detachably connected to the pressure roller 4. An elastic ring 61 is fixedly connected to the outer circumferential surface of the mounting ring 6. The pressure roller 4 is connected to a fixing component 7, and the mounting ring 6 is fixedly connected to the pressure roller 4 through the fixing component 7. The fixing component 7 includes a positioning part 71 fixedly connected to the pressure roller 4 and a fixing block 72 threadedly connected to the pressure roller 4. The positioning part 71 is located between the driven bevel gear 41 and the mounting ring 6, and the mounting ring 6 is located between the positioning part 71 and the fixing block 72. Two stop parts 62 are arranged opposite each other on the inner ring of the mounting ring 6. The stop parts 62 are integrally formed with the mounting ring 6. The outer circumferential surface of the pressure roller 4 has a stop groove 42 that corresponds one-to-one with the stop parts 62. The stop parts 62 are engaged in the stop grooves 42 and fit against the inner wall of the stop grooves 42. The pressure roller 4 is slidably connected to a reset plate 8, which is located between the mounting ring 6 and the positioning part 71. The mounting ring 6 abuts against the reset plate 8. The positioning part 71 is connected to several reset elements 9, which are springs. The positioning part 71 has an annular groove 711 on the side away from the driven bevel gear 41. The reset elements 9 are located in the annular groove 711. One end of the reset element 9 is fixedly connected to the inner wall of the annular groove 711, and the other end is fixedly connected to the reset plate 8. When the mounting ring 6 is sleeved on the pressure roller 4, the fixing block 72 is threadedly connected to the pressure roller 4, and the fixing block 72 abuts against the mounting ring 6.

[0040] The implementation principle of a sliding table saw according to an embodiment of this application is as follows: A wooden board is placed on the cutting table 1, and one side of the wooden board abuts against the positioning strip 14, so that the wooden board is accurately installed in the corresponding position, and the carrier plate 2 is located above the wooden board. The hydraulic cylinder 31 drives the carrier plate 2 to slide towards the wooden board until the elastic ring 61 abuts against the wooden board. The second driving member 52 drives the linkage rod 51 to rotate. All the active bevel gears 511 rotate around the axis of the linkage rod 51. During the rotation of the active bevel gears 511, the passive bevel gears 41 are driven to rotate, so that each elastic ring 61 rotates in the same direction. During the rotation of the pressure roller 4, the wooden board is moved towards the circular saw 11, thereby completing the cutting of the wooden board. This avoids the operator pushing the wooden board by hand, prevents the circular saw 11 from injuring the hand, and improves the safety of operation.

[0041] 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.
