Description

TECHNICAL FIELD

[0001] The utility model relates to four edge saw technical field, concretely is an improved wood four edge saw. BACKGROUND

[0002] Four edge saw is mainly used for cutting and processing the four edges of wood and other boards to obtain the required size and shape, and the structure of four edge saw mainly includes:

[0003] Sawing mechanism: the core component of four edge saw, usually composed of multiple saw blades, including main saw blade and side cutting saw blade, the main saw blade is used for cutting the board vertically to determine the length of the board, and the side cutting saw blade is used for cutting the two side edges of the board horizontally to control the width of the board. These saw blades are generally installed on adjustable saw shafts and driven by motors to rotate at high speed to realize sawing of the board;

[0004] Conveying mechanism: mainly composed of conveying belt, rollers and the like, the conveying belt is used for carrying the board and conveying it to the sawing area, and the rollers play the role of supporting and guiding the board to ensure that the board remains stable during the conveying process and can be accurately positioned to the sawing position;

[0005] Positioning and pressing mechanism: including positioning baffle and pressing device, the positioning baffle is used for determining the sawing position of the board to ensure the accuracy of the cutting size, and the pressing device presses the board during sawing to prevent it from moving or shaking under the action of sawing force to ensure the sawing quality and operation safety;

[0006] Control system: used for controlling the cooperative work of various components of four edge saw. It can realize accurate adjustment of parameters such as sawing speed, conveying speed, saw blade feed amount, and can also realize automatic operation, such as automatic completion of the positioning, sawing and conveying processes of the board according to the preset size parameters;

[0007] Its working principle is as follows: When the four-sided saw is working, the board to be processed is first placed on the conveyor belt. The conveyor belt transports the board to the positioning baffle for positioning. At this time, the clamping device will firmly press the board down. Then, the saw blade of the sawing mechanism starts to rotate and saws the board on all four sides according to the set dimensional parameters. After sawing, the conveyor belt transports the sawn board out of the sawing area, completing one sawing process. Through the precise control of the control system, continuous, efficient, and accurate four-sided sawing of boards can be achieved. Existing four-sided saws have protective covers installed in the saw blade's working area. These covers not only shield the rotating area of ​​the saw blade but also intercept sawing debris. A suction pipe is installed at the top of the protective cover to collect the debris. However, in actual operation, the suction pipe is located at the bottom of the protective cover. During suction, the high-speed rotation of the saw blade interferes with the suction airflow, weakening the suction force near the board surface. This results in some debris remaining on the board surface. After a period of operation, debris adheres to the four-sided saw, impacting the working environment and requiring manual cleaning, increasing workload. Therefore, an improved woodworking four-sided saw is proposed. Utility Model Content
