The existing sawing machines have a fixed and simple structure. When cutting wooden boards, they still need to be manually guided, which is inefficient. When pushing the wooden boards for cutting, the wooden boards are prone to deflection and are easily affected by the vibration of the machine to produce slight vibrations, resulting in lower cutting accuracy. To this end, we proposed a downward pressing device for a sawing machine. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figures 1 to 3 The utility model provides a technical solution: a pressing device for a sawing machine, comprising an operating table 15, an L-shaped seat 19 is arranged above the operating table 15, the bottom of the L-shaped seat 19 is slidably connected to the side wall of the operating table 15, a cutting device is connected to the L-shaped seat 19 through a lifting device, and a pressing device is fixedly connected to one side of the lifting device;

[0021] The pressing device includes a mounting frame 6 fixedly connected to one side of the lifting device, a U-shaped seat 4 with an opening downward is provided directly below the mounting frame 6, a pressing roller 9 is connected to the U-shaped seat 4 via a rotating shaft, and a plurality of guide rods 5 are vertically connected to the top of the U-shaped seat 4;

[0023] like Figure 1 , 3 As shown, the lifting device can be lifted and lowered with the mounting frame 6 so that the pressure roller 9 at the bottom of the mounting frame 6 first contacts the wooden board, and the cutting device then cuts the wooden board after the contact and pressing, thereby achieving the goal of first fixing the wooden board and then cutting it, and after the cutting is completed, the cutting device is first separated from the wooden board, and then the pressure roller 9 is separated from the wooden board, thereby avoiding the cutting device from affecting the wooden board when it is separated from the wooden board.

[0024] Furthermore, a strip seat 2 is fixedly connected to the side wall of the operating table 15, a slide slot 1 is provided on the top of the strip seat 2, a first screw 21 is connected to the slide slot 1 through a bearing, one end of the first screw 21 passes through the strip seat 2 and is coaxially connected to a second motor 22, and the second motor 22 is fastened to the operating table 15;

[0025] The bottom of the L-shaped seat 19 is fixedly connected with a slider 3 , the slider 3 is slidably connected in the slide groove 1 , and the first screw rod 21 passes through the slider 3 and is threadedly connected thereto.

[0026] like Figure 2As shown, the second motor 22 is connected to the switch through a wire, and the second motor 22 drives the first screw 21 to rotate. Since the slider 3 is threadedly connected to the first screw 21, the slider 3 can be driven to move in the slide groove 1, and then the L-shaped seat 19 can be moved along the side wall of the operating table 15, and then the cutting device can be driven to move, avoiding pushing the wooden board to be cut, and further improving the cutting quality.

[0027] Furthermore, the lifting device includes a U-shaped frame 14 with an opening facing upward, the top of the U-shaped frame 14 passes through an L-shaped seat 19, a cross plate 12 is fixedly connected inside the U-shaped frame 14, a hydraulic telescopic rod 18 is vertically connected between the cross plate 12 and the L-shaped seat 19, and the cutting device is slidably connected to the bottom of the U-shaped frame 14.

[0028] like Figure 1 As shown, the hydraulic telescopic rod 18 drives the U-shaped frame 14 to be raised and lowered, thereby realizing the raising and lowering adjustment of the cutting device, thereby meeting the cutting requirements of wooden boards of different thicknesses and improving the practicability of the device.

[0029] Furthermore, the U-shaped frame 14 is connected to the L-shaped seat 19 via the guide seat 16 , and the top of the U-shaped frame 14 is fixedly connected to the limiting block 17 , thereby ensuring stable up and down sliding between the U-shaped frame 14 and the L-shaped seat 19 .

[0030] Further, the cutting device includes a sliding seat 23, a through slot 20 is provided at the bottom of the U-shaped frame 14, the sliding seat 23 is slidably connected to the through slot 20, and a second screw 24 is coaxially connected to the sliding seat 23, both ends of the second screw 24 are connected to the side wall of the U-shaped frame 14 through bearings, and one end of the second screw 24 is coaxially connected to the first motor 13, and the first motor 13 is fastened to the outer wall of the U-shaped frame 14;

[0031] The bottom of the sliding seat 23 is fixedly connected to a motor box 10 , the interior of the motor box 10 is fixedly connected to a driving motor, and the output end of the driving motor passes through the exterior of the motor box 10 and is coaxially connected to a saw blade 11 .

[0032] like Figure 3 As shown, the first motor 13 and the driving motor are connected to the control switch through wires. When the first motor 13 works, it can drive the sliding seat 23 to adjust horizontally on the second screw rod 24, and cooperate with the rotating saw blade 11 to achieve normal cutting of the wooden board.

[0033] Furthermore, the plane where the bottom surface of the saw blade 11 is located is higher than the plane where the bottom surface of the pressure roller 9 is located, so that the pressure roller 9 can contact the wooden board first, and the saw blade 11 can cut the wooden board later, thereby avoiding shaking and tilting of the wooden board.

[0034] To sum up, when the pressing device of the sawing machine is in use, the template to be cut is placed on the top of the operating table 15, and the second motor 22 drives the L-shaped seat 19 to move according to the required cutting distance. After moving to the position where cutting is required, the hydraulic telescopic rod 18 controls the U-shaped frame 14 to move downward. During the movement, the pressure roller 9 first contacts the wooden board. After the wooden board is fixed, the saw blade 11 can cut the wooden board under the drive of the driving motor and the first motor 13. After the cutting is completed, the hydraulic telescopic rod 18 drives the saw blade 11 to move upward. Under the elastic force of the reset spring 7, the saw blade 11 can be separated from the wooden board first, and then the pressure roller 9 is separated from the wooden board, which not only ensures that the wooden board will not be offset during and after cutting.
