When the extension supporting assembly 40 is not used, the supporting plate 41 is pushed, the pulling rod 42 is inserted into the pulling groove 110, and the supporting plate 41 is attached to the side edge of the platform panel 11, as shown in fig. 1.
In the actual design, the sliding grooves 20 and the drawing grooves 110 should be coated with lubricating oil to improve the free sliding effect.
In addition, there should be a gap between the cutting wheel 50 and the strip notch 14 to avoid the cutting wheel 50 from contacting and wearing away from the strip notch 14 when rotating at high speed.
In the present invention, the driving motor, the dust blower 70 and the negative pressure blower 90 are existing devices in the art. In practical designs, the driving motor may be protected by a protective net to prevent debris sucked into the cabinet 101 from affecting the operation of the driving motor.
When the wood cutting table is used, a wood plate to be cut is placed on the table top plate 11 of the cutting table 10, the position, needing to be cut, on the wood plate is aligned to the cutting wheel 50, then the switch is pressed, the power supply supplies power to the driving motor, the dust blowing fan 70 and the negative pressure fan 90 at the moment, the driving motor drives the cutting wheel 50 to rotate at a high speed, and the dust blowing fan 70 and the negative pressure fan 90 start to operate. Then, the operator holds the grip handle 340 and presses downward, the pressing plate 37 is driven to press tightly on the top surface of the wood plate, and at this time, the grip handle 340 is slowly pushed toward the cutting wheel 50 along the feeding direction, so that the whole feeding mechanism 30 can slide in the chute 20 by the sliding block 32, and the pressing plate 37 drives the wood plate to move along the feeding direction by the friction force between the pressing plate 37 and the wood plate (if the non-slip mat 38 is designed, the driving effect of the friction force is better), so as to complete the cutting after moving to the cutting wheel 50 rotating at high speed. When the cut is complete, the operator releases the handle 340 so that the platen 37 is returned to the upward position by the spring 36, which pulls the entire feed mechanism 30 back to the starting position.
Of course, during the whole cutting process, the operator can push the wood plate to move a certain distance towards the cutting wheel 50, then release the holding handle 340, pull the whole feeding mechanism 30 back to other positions on the wood plate, and then push the wood plate towards the cutting wheel 50 repeatedly.

In addition, in the cutting process, the dust blowing fan 70 blows air towards the cutting wheel 50 below continuously, the negative pressure fan 90 continuously pumps air into the closed space formed by the table panel 11 and the case 101 (or the inside of the chip collecting box 80) to form a negative pressure effect, so that under the cooperation of the dust blowing fan 70 and the negative pressure fan 90, chips generated by cutting are blocked by the chip blocking plate 60, and simultaneously enter the chip collecting box 80 below the table panel 11 through the screen 15 together with air to be collected, the chips are effectively prevented from scattering, and the cutting environment is cleaner and more sanitary. And the cooperation of the dust blowing fan 70 and the negative pressure fan 90 also enables the effect of air circulation to be generated around the cutting wheel 50, so that the heat generated by the cutting wheel 50 in the cutting process can be rapidly taken away by the circulating air, and a good heat dissipation effect is achieved.
When the debris needs to be cleaned, the maintenance door 12 is opened only through the locking screw 13, and the debris collection box 80 is taken out and falls to the debris.
When maintenance of equipment such as a drive motor is required, the maintenance door 12 is opened by the lock screw 13 to observe the situation and perform maintenance work.
The invention has the advantages that:
the invention can realize the cutting operation of the timber board, and simultaneously, the limbs of an operator, particularly the hands can be far away from the cutting wheel in the process of pressing and pushing the timber board on the cutting table, thereby effectively avoiding the occurrence of safety accidents, and the scraps generated by cutting can be quickly and effectively collected, thereby avoiding the scraps from flying, ensuring the cleanness and sanitation of the whole cutting environment, preventing the scraps from being sucked into the human body and furthest ensuring the personal safety of the operator.
