Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, specifically to an energy-saving band saw for wood processing. Background Technology

[0002] A band saw is a processing device that uses a ring-shaped, endless band saw blade as the saw tool. The blade moves in a unidirectional, continuous linear motion around the saw wheel to cut materials. It is widely used in the timber industry and can be used to split logs, split boards and squares, saw large boards into thin boards or small squares, cut rough-edged boards into straight-edged boards or squares, and perform various cutting operations such as curves, right angles, bends, bevels, and conical shapes.

[0003] For example, the "Wood Processing Band Saw" disclosed in Chinese Patent CN218018986U includes a machine body, a motor, a drive wheel, a saw band, and a driven wheel. A placement plate is fixedly connected to the outer wall of the machine body. A conveying roller is rotatably connected to the top of the placement plate, and a sliding plate is slidably connected to the top of the placement plate. A threaded rod is threadedly connected to the bottom of the sliding plate, and a turntable is fixedly connected to the end of the threaded rod. A sliding rod is slidably connected to the bottom of the sliding plate.

[0004] Although the aforementioned utility model achieves efficient wood transport under manual pushing through the coordinated operation of conveyor rollers, guide rollers, and cylinders, reducing friction between the wood and the placement board and thus improving the efficiency of wood cutting and processing, manual assistance is still required during the cutting process. This makes the wood processing inconvenient, cumbersome, and time-consuming, ultimately reducing the processing efficiency of the boards. Utility Model Content

The transmission disc 3 is used to position and drive the saw band 4, ensuring the stable operation of the band saw. The transmission shaft 7, through its cooperation with the first bevel gear 6 and the second bevel gear 9, enables the pusher wheel 8 to rotate synchronously, allowing for simultaneous feeding and cutting.

[0023] Also includes: reference Figures 1 to 3 As shown, the driven plate 12 is slidably mounted on the housing 2, and the saw blade 4 passes through the interior of the driven plate 12; several guide rods 13 are slidably mounted on the driven plate 12, and the guide rods 13 are perpendicular to the driven plate 12; two pressure plates 14 are fixedly mounted on the bottom of the guide rods 13, and the pressure plates 14 are located on both sides of the saw blade 4; the adjusting screw 19 is rotatably mounted on the housing 2, and the outer surface of the adjusting screw 19 is threaded with the interior of the driven plate 12. When the adjusting screw 19 is rotated, the driven plate 12 moves along the axial direction of the adjusting screw 19. By setting the driven plate 12, the height can be adjusted under the action of the adjusting screw 19, so as to press and position wooden boards of different thicknesses. By setting the guide rods 13, the pressure plates 14 can be positioned and guided.

[0024] It also includes: combination Figures 1 to 3 As shown, a limiting rod 21 is fixedly mounted on the housing 2, and the driven plate 12 is slidably mounted inside the limiting rod 21 on its outer surface. The limiting rod 21 has a T-shaped cross-section. Several pressure rollers 15 are rotatably mounted on the pressure plate 14, and the surfaces of the pressure rollers 15 are in contact with the surface of the wooden board. A servo motor 20 is fixedly mounted on the housing 2, and its output end is driven. By setting the limiting rod 21, the driven plate 12 can be limited, improving its stability. By setting the pressure rollers 15, the friction between the pressure plate 14 and the wooden board can be reduced, making it easier for the wooden board to move.

[0025] Also includes: reference Figure 2As shown, the guide sleeve 17 is fixedly mounted on the driven plate 12, and the outer surface of the guide rod 13 is slidably mounted inside the guide sleeve 17; the limiting block 18 is fixedly mounted on the top of the guide rod 13; and several auxiliary wheels 11 are rotatably mounted on the worktable 1.

The clamping plate 23 can fix the wooden board, and the adjusting screw 26 can adjust the position of the clamping plate 23, facilitating cutting the wooden board at different positions and improving the practicality of the device.

[0027] Also includes: reference Figure 4 As shown, several rollers 24 are rotatably disposed inside the clamping plate 23; a driven belt 25 is driven on the surface of the rollers 24. By distributing the rollers 24 to the driven belt 25, the wooden board can be moved during the clamping and fixing process.

By setting the compression spring 16, the pressure plate 14 can be flexibly pressed to prevent the wooden board from being inconvenient to move due to excessive pressing.

[0029] The energy-saving band saw for wood processing described in this utility model has a specific working principle that can be combined with... Figures 1 to 4 And implement it with reference to the following process description:

[0030] First, the worker places the wooden board to be cut on the workbench 1, ensuring one end of the board is tightly against the saw blade 4. Then, the servo motor 20 is activated, driving the adjusting screw 19 to rotate, causing the driven plate 12 to move downwards. During this movement, the pressure roller 15 on the pressure plate 14 tightly contacts the surface of the wooden board, thus stably fixing it in place. Next, the worker activates the drive motor 5, which simultaneously rotates the transmission disc 3 and the first bevel gear 6. The rotation of the transmission disc 3 starts the saw blade 4 working, and the rotation of the first bevel gear 6, meshing with the transmission shaft 7, drives the transmission shaft 7 to rotate. The transmission shaft 7 then drives the pusher wheel 8, connected to the second bevel gear 9, to rotate, thus achieving the conveying and cutting of the wooden board.
