[0032] A woodworking band saw for facilitating the replacement of saw blades, such as Figures 1 - 3As shown in the figure, it includes a saw table 10 and a flexible saw band 50. On one side of the top of the saw table 10, a top frame 20 is installed. Above the saw table 10, two groups of fixed saw band pulleys 30 and one group of adjustable saw band pulleys 40 are installed on the same plane. An adjusting mechanism 60 for adjusting the position of the adjustable saw band pulley 40 is installed on the top frame 20. The two groups of fixed saw band pulleys 30 are respectively arranged on the upper and lower sides of the saw table 10. A saw band groove 12 for installing the flexible saw band 50 is opened on the surface of the saw table 10. A cross seat 21 for fixing one group of fixed saw band pulleys 30 is connected to the top frame 20. A servo motor 22 for driving the fixed saw band pulley 30 is installed on the cross seat 21. On one side of the bottom of the saw table 10, a side plate 14 for fixing the other group of fixed saw band pulleys 30 is installed. The adjusting mechanism 60 includes an adjusting cylinder 61. The piston rod 62 of the adjusting cylinder 61 passes through the top frame 20 and is connected to an L-shaped mounting seat 63. The adjustable saw band pulley 40 is rotatably connected to the mounting seat 63 through a locking ring seat 64. The adjusting mechanism 60 installed on the top frame 20 for adjusting the position of the adjustable saw band pulley 40, in combination with the adjusting cylinder 61 and the L-shaped mounting seat 63, enables the position of the adjustable saw band pulley 40 to be adjusted flexibly, greatly facilitating the adjustment of the saw blade tension and the rapid replacement of saw blades of different specifications or worn ones according to processing requirements, improving work efficiency and flexibility. Combined with the saw band groove 12 opened on the surface of the saw table 10, it provides a stable and parallel running track for the flexible saw band 50, ensuring the smoothness and accuracy of the sawing process. The precise control characteristics of the servo motor further improve the efficiency and accuracy of the sawing operation, while reducing energy consumption and noise.

[0033] Furthermore, support seats 11 are symmetrically arranged on both sides of the bottom of the saw table 10. At both ends of the bottom of each group of support seats 11, two groups of moving wheels 13 are symmetrically arranged, enabling the entire saw table to move easily within the working area, improving the flexibility of the equipment. Operators can quickly adjust the position of the saw table according to needs to adapt to different working environments or processing requirements. At the same time, the design of the moving wheels also facilitates the handling and storage of the equipment.

[0034] It is worth noting that the number of saw band grooves 12 on the saw table 10 is two, which improves the structural stability.

[0035] Specifically, the output shaft of the servo motor 22 passes through the cross seat 21 and is coaxially connected to the fixed saw band pulley 30. The precise control of the servo motor ensures the stability of the sawing speed and the consistency of the sawing quality.

[0036] In addition, the edge cross-sections of the fixed saw band wheel 30 and the adjustable saw band wheel 40 are U-shaped, and the width of the U-shaped groove is the same as that of the flexible saw band 50, ensuring the stability and reliability of the saw band during transmission, helping to reduce the vibration and deviation of the saw band, improving the sawing accuracy and smoothness. The flexible saw band 50 is drivingly connected to the fixed saw band wheel 30 and the adjustable saw band wheel 40, enabling the saw band to rotate smoothly on the saw band wheels and ensuring the continuity and efficiency of the sawing operation.

[0037] Working principle of this woodworking band saw machine facilitating saw blade replacement:

[0038] First, place the flexible saw band 50 in the saw band groove 12 formed on the surface of the saw table 10.

[0039] Then, start the servo motor 22 on the cross base 21 to drive the rotation of the fixed saw band wheel 30 located above the saw table 10.

[0040] Meanwhile, adjust the position of the adjustable saw band wheel 40 through the adjusting mechanism 60 on the top frame ২০. Specifically, the adjusting cylinder 61 operates, and its piston rod 62 pushes the mounting seat 63 with an L-shaped cross-section to move, thereby driving the adjustable saw band wheel 40 rotatably connected thereto through the locking ring seat 64 to move to a proper position, enabling the flexible saw band 50 to be tensioned and operate normally.

[0041] The side plate 14 on one side at the bottom of the saw table 10 is used to fix another set of fixed saw band wheels 30 to ensure the stable operation of the entire saw blade system.
