[0027] The working principle of the utility model is:

[0028] I. Up and down trimming and front and rear head processing mode of plate

[0029] 1. After power-on, the electric control switch is turned to the head opening mode, and the initial positions of the trimming structure are respectively adjusted by the cylinder action to make the front trimming mechanism be below and the rear trimming mechanism be above

[0030] 2. When the plate reaches the front travel switch of the trimming mechanism, the cutter head of the rear trimming mechanism moves below the bottom surface of the plate, and with the plate moving forward, the cutter head of the rear trimming mechanism performs trimming processing on the bottom surface of the plate;

[0031] 3. When the front end of the plate reaches the front trimming mechanism, the front end of the plate contacts the cutter head of the front trimming mechanism, and with the plate moving forward, the cutter head of the front trimming mechanism completes the head trimming processing on the front end of the plate, and then the cutter head of the front trimming mechanism starts to perform trimming processing on the top surface of the plate, and at the same time, the cutter head of the rear trimming mechanism continues to perform trimming processing on the bottom surface of the plate;

[0032] 4. The plate continues to move forward, and when the plate leaves the contact switch, the cutter head of the rear trimming mechanism completes the trimming processing on the bottom surface of the plate, the cylinder of the rear trimming mechanism pulls the sliding frame to move upward on the sliding rail of the slanting base, the cutter head of the rear trimming mechanism starts to perform head trimming processing on the rear end of the plate, and at the same time, the cutter head of the front trimming mechanism continues to perform trimming processing on the top surface of the plate, until the plate leaves the trimming mechanism, thereby completing the trimming and head processing of the plate, and the dust generated in the trimming process is absorbed and processed by the dust suction pipe.

[0033] II. The plate only needs to be trimmed up and down, without front and back head processing mode

[0034] When the plate only needs to be trimmed up and down without head processing, only need to handle plate thickness specifications, through the upper limit bolt of the front trimming mechanism to limit the cylinder stroke of the trimming mechanism, so that the trimming motor cutter of the rear trimming mechanism driven by the cylinder can only displace to the top edge of the processed plate. During the adjustment process of the limit bolt, as the limit bolt rotates, the limit bolt drives the synchronous rotating shaft sleeve to rotate synchronously through the pin shaft, and the synchronous rotating shaft sleeve only rotates without displacement. In this way, the digital display on the top of the synchronous rotating shaft sleeve synchronously displays the displacement data of the limit bolt, so as to accurately control the displacement of the rear trimming motor cutter.

[0035] 1. Specific process: after power-on, the electric control switch is turned to the head mode, and the initial position of the trimming structure is respectively above the front trimming mechanism and below the rear trimming mechanism by the action of the cylinder. When the plate reaches the front travel switch of the trimming mechanism, in this mode process, the front and rear trimming mechanism cylinders are not in action.

As the plate moves forward, the cutter of the front trimming mechanism cuts the top surface of the plate. The dust generated in the trimming process is absorbed and treated through the dust suction pipe.
