[0019] The effects provided in the content of the invention are only the effects of the embodiments, not all the effects of the invention. One of the above technical solutions has the following advantages or beneficial effects:

[0020] 1. The present invention realizes that the horizontal distance between the limiter and the cutter head is adjustable by the relative horizontal sliding of the limiter and the upper trimming device. When trimming, the plate is attached to the limiter, so that the horizontal distance between the side of the plate and the cutter head is adjustable, so that the position of the cutter head can be adjusted according to the distance between the excess edge band of the plate and the edge of the plate, so that the edge band of the vertical side of the plate can be trimmed, and the edge band of the non-vertical side can be trimmed, thereby improving the adaptability of the equipment.

[0021] 2. The present invention is provided with a lower trimming device through a mirror image below the upper trimming device. The upper trimming device and the lower trimming device can work together to trim the upper and lower sides of the plate at the same time, thereby improving work efficiency. The lower trimming device is horizontally slidably arranged on the connecting plate to adjust the horizontal position of the lower trimming cutter head, so that the position of the cutter head can be adjusted according to the distance between the excess edge banding on the upper and lower sides of the plate and the edge of the plate.

[0022] 3. In the present invention, a second position adjustment device is provided between the lower trimming device and the connecting plate, and a position adjustment device is provided between the upper trimming device and the connecting plate. Compared with directly adjusting the positions of the upper trimming device and the lower trimming device by hand, the position adjustment has higher accuracy, and the position stability of the upper trimming device and the lower trimming device after adjustment is better.

[0023] 4. The trimming cutter head of the present invention is installed on the driving shaft of the motor, and the motor drives the trimming cutter head to rotate to perform trimming work. The motor is vertically slidably arranged on the mounting plate, so that the motor and the cutter head can move up and down. The height adjustment device is connected to the motor, and the height of the trimming cutter head is adjusted through the height adjustment device to adapt to the thickness of the plate, so that the cutter head fits the upper or lower side of the plate, ensuring that the edge band is flush with the plate after trimming, thereby improving the work quality.

[0024] 5. The present invention arranges a support member on the side of the trimming cutter head, and the support member contacts the upper or lower side of the plate. The lower support member supports the plate, and the upper support member limits the plate on the one hand to keep the plate horizontally placed, and on the other hand realizes the positioning of the trimming cutter head of the upper trimming device to keep the vertical distance between the cutter head and the plate at the optimal position.

[0025] 6. An air outlet is provided on the side where the limiter and the support plate contact each other. The limiter and the support are also provided with an air inlet connected with the air outlet. The air inlet is connected to an external air source, and the gas is discharged through the air outlet. The pressure generated when the gas is discharged is used to support the plate, thereby reducing the friction between the limiter or the support plate and the plate, which not only saves effort when pushing the plate, but also prevents the plate from being damaged due to excessive contact with the limiter or the support, thereby protecting the plate.

[0026] 7. The present invention is arranged on a fixed plate by sliding a connecting plate, the fixed plate is provided with an elongated hole, the connecting plate slides in the elongated hole, an elastic member is provided between the connecting plate and the fixed plate, so that the trimming device and the limiting member can move together in the horizontal direction, thereby solving the problem of damage to the plate on the limiting member due to the uneven side of the plate, and a certain pressure is exerted between the limiting member and the plate through the elastic member, thereby ensuring that the plate is always in contact with the limiting member.

[0027] 8. The present invention provides limiting screws on both sides of the connecting plate. The sliding range of the connecting plate can be adjusted by the limiting screws on both sides. The sliding range and sliding position of the trimming device and the horizontal position of the limiting member can be adjusted according to needs, thereby adjusting the pulling force generated by the elastic member on the connecting plate, thereby solving the processing quality problem caused by excessive or insufficient pressure between the limiting member and the plate due to the sliding range or sliding position: excessive pressure damages the plate, and insufficient pressure causes insufficient tightness between the plate and the limiting member.
