[0025] The pushing mechanism includes a stepper motor 8 fixed to one end of the base bar shell 1, the main shaft end of the stepper motor 8 penetrates into the base bar shell 1 and is fixedly connected to a threaded rod 9, a nut block 10 is threadedly connected to the threaded rod 9, and a moving frame 11 is fixedly connected to the upper end of the nut block 10. An opening 12 is opened on the upper side wall of the base bar shell 1, and the moving frame 11 passes through the opening 12 and is fixedly connected to a push plate 13;

[0026] When the wood is placed and fed into the sawing machine, the stepper motor 8 is started to drive the threaded rod 9 to rotate. Since the threaded rod 9 is threadedly connected to the nut block 10, the nut block 10 is forced to move, driving the push plate 13 fixed to the mobile frame 11 to move. The push plate 13 can push the wood to move horizontally into the sawing machine for feeding. The feeding is stable and only one motor is required. Compared with the prior art of the background technology, the equipment investment cost is lower, the energy consumption is less, the maintenance is convenient, and it is easy to popularize and use.

[0027] like Figure 4 As shown: the spacing adjustment mechanism includes a hand crank 14 inserted at one end of the rectangular strip shell 2 and rotatably connected thereto, one end of the hand crank 14 is fixedly connected to a bidirectional screw rod 15, and two symmetrically arranged threaded blocks 16 are threadedly connected to the bidirectional screw rod 15, and the upper ends of the two threaded blocks 16 are fixedly connected to a connecting rod 17, and the upper side wall of the rectangular strip shell 2 is provided with two sliding openings 18, and the two connecting rods 17 respectively pass through the two sliding openings 18 and are respectively fixedly connected to the two mounting plates 3. When it is necessary to adjust the spacing of the two guide rollers 5 according to the diameter specifications of the wood, the hand crank 14 is rotated to drive the bidirectional screw rod 15 to rotate. Since the bidirectional screw rod 15 is threadedly connected to the two threaded blocks 16 respectively, at this time, the two threaded blocks 16 are forced to move in opposite directions, thereby driving the mounting plate 3 fixed to the connecting rod 17 to move, so as to realize the adjustment of the spacing between the two guide rollers 5, so as to carry out tight guiding feeding for wood of different diameter specifications.

[0028] like Figure 3 As shown, the inner walls on both sides of the sliding opening 18 are slidably connected to the side walls on both sides of the connecting rod 17, so that the displacement of the connecting rod 17 is more stable.

[0029] like Figure 3 and Figure 4 As shown: the elastic pressure relief mechanism includes two slide bars 19 inserted into the side wall of the mounting plate 3 and slidably connected thereto, the first ends of the two slide bars 19 are fixedly connected to the concave plate 4, the second ends of the two slide bars 19 are fixedly connected to the connecting plate 20, and two tension springs 21 are fixedly connected between the mounting plate 3 and the connecting plate 20, and the two tension springs 21 are respectively sleeved on the outer sides of the two slide bars 19. When the two guide rollers 5 are pressed against the two sides of the wood, at this time, the concave plate 4 pushes the two slide bars 19 to move, and then pushes the connecting plate 20 to move and pull the two tension springs 21 to stretch to generate elastic force, and the elastic force rebounds to make the guide rollers 5 press against the wood to prevent the wood from being squeezed by excessive pressure. At the same time, it can adapt to different concave and convex surfaces of the wood for continuous pressing.

[0030] like Figure 2 As shown, the inner walls on both sides of the opening 12 are frictionally connected with the side walls on both sides of the moving frame 11, so that the displacement of the moving frame 11 is stable.

[0031] like Figure 1 As shown: the side wall of the mounting plate 3 is rotatably connected with a supporting roller 22, and the supporting roller 22 and the supporting roller 7 are located at the same horizontal height, which can support the wood and provide more stable support.

[0032] like Figure 1 and Figure 2 As shown, the distance between the two opposing support rollers 7 is greater than the width of the moving frame 11 , which facilitates the displacement of the moving frame 11 .

[0033] Working principle: When using this device to feed wood to the sawing machine, place the wood on the support roller 7, one end of the push plate 13 is pressed against one end of the wood, and the hand crank 14 is rotated first to drive the bidirectional screw rod 15 to rotate. Since the bidirectional screw rod 15 is threadedly connected with the two threaded blocks 16 respectively, at this time, the two threaded blocks 16 are forced to move in opposite directions, thereby driving the mounting plate 3 fixed to the connecting rod 17 to move, and the spacing between the two guide rollers 5 can be adjusted to allow wood of different diameters to be pressed against and guided for feeding. The guide rollers 5 can press against both sides of the wood to position and guide the transportation of the wood, making the wood feeding more stable and accurate to prevent deviation.

[0034] Then, the stepper motor 8 is started to work, driving the threaded rod 9 to rotate. Since the threaded rod 9 is threadedly connected to the nut block 10, the nut block 10 is forced to move, driving the push plate 13 fixed to the mobile frame 11 to move. The push plate 13 can push the wood to move horizontally into the sawing machine for feeding. The feeding is stable, and only one motor is required. Compared with the prior art of the background technology, the equipment investment cost is lower, the energy consumption is less, the maintenance is convenient, and it is easy to popularize and use;

[0035] Secondly, when the two guide rollers 5 are pressed against the two sides of the wood, at this time, the concave plate 4 pushes the two slide bars 19 to move, and then pushes the connecting plate 20 to move and pull the two tension springs 21 to stretch to generate elastic force. The elastic force rebounds to make the guide rollers 5 press against the wood to prevent the wood from being squeezed by excessive pressure. At the same time, it can adapt to the different concave and convex surfaces of the wood for continuous pressing.

[0036] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
