[0002] Composite board lines are usually processed by automated production lines. During the processing, they are cut according to the required length. When the composite board line is continuously produced and cut to length, since the panel is made of metal sheet (thickness is generally 0.4-0.8mm), the middle material is polyurethane with a cellular structure, phenolic organic foam plastic or rock wool, glass wool inorganic insulation material, the core material is relatively soft, and when the cross section is cut by a band saw, the steel plate on the surface will cause more burrs, and this burr is very difficult to remove, which can easily cause scratches on the surface of the composite board, and will also cause scratches during installation and other great safety hazards.

[0003] In the prior art, there is no better solution for online continuous production, and the only way is to use manual files for repair or automatic scrapers for scraping. The main problems are:

[0017] A hand wheel is installed on the top of the panel, and the hand wheel is connected to a screw mechanism to control the up and down sliding of the panel.

[0018] The cross section of the guide sleeve is in a "π"-shaped structure.

[0019] The baffle is made of three plates to form a "[" structure.

[0020] The structure of the rotary cutting tool assembly is as follows: it includes a main shaft of an integrated structure, a cutter head is installed on the head of the main shaft, an L-shaped plate is fixed on the outer circumference of the main shaft, a right angle plate of the L-shaped plate is parallel to the axis direction of the main shaft, and another right angle plate is arranged beside the cutter head;

[0021] The outer end surface of the L-shaped plate is also parallelly and spaced apart with a rear plate and a limit plate, an adjusting stud is installed between the rear plate and the limit plate, and a groove is arranged in the middle of the limit plate, and the groove cooperates with the cutter head.

[0024] An operating method of a composite plate sawing online tracking deburring limit control device includes the following operating steps:

[0025] Step 1: Initial state: The driving motor is in the initial position, the rotary cutting tool assembly and the limit compensation assembly on the carriage are away from the workpiece, and the compression spring of the limit compensation assembly is in a free state at this time;

[0026] Step 2: Importing state: Start the drive motor, the reducer drives the synchronous wheel to rotate, and the synchronous belt drives the carriage to move;

[0077] The operation method of the composite plate sawing online tracking deburring limit control device of this embodiment includes the following operation steps:

[0078] Step 1: Initial state: The driving motor 11 is in the initial position, the rotary cutting tool assembly 2 and the limit compensation assembly 3 on the carriage 4 are away from the workpiece 1, and at this time, the compression spring 303 of the limit compensation assembly 3 is in a free state;

[0079] Step 2: Importing state: Start the driving motor 11 to work, the reducer 10 drives the synchronous wheel 9 to rotate, and the synchronous belt 8 drives the carriage 4 to move;

[0080] At the same time, the driving cylinder 307 is actuated, the piston rod 306 extends, pushes the top plate 305, and compresses the compression spring 303.
