[0021] Embodiment 1:

[0022] This device uses electric control to realize automatic tooth punching operation. The main structure includes:

[0023] A support base 1 has a rectangular frame structure 2 fixed on the top of the support base 1, and the frame structure 2 is used to assist in the installation and positioning of other components.

[0024] A pallet 3 is fixedly installed on the top of one side of the frame structure 2. The pallet 3 is an operating pallet 3 specially used for carpenters and is used to place and support wooden boards.

[0025] The platen 3 is provided with strip-shaped holes 4 symmetrically on the left and right, and the length direction of the strip-shaped holes 4 is adapted to the length direction of the platen 3. A limit frame 5 is provided above the strip-shaped holes 4 and is perpendicular to the length direction of the platen 3. Two limit frames 5 are arranged in parallel, and the limit frames 5 are of L-shaped structure, and upright limit surfaces 6 are provided on the inner sides of the adjacent sides of the two limit frames 5. Based on the limit surfaces 6, the plate between the two is limited and assisted to maintain its vertical feeding with the tooth punching direction.

[0026] The limiting frame 5 is penetrated by a positioning bolt 7 , which penetrates the strip-shaped hole 4 and fixes the limiting frame 5 on the platen 3 through a nut member matched therewith.

[0027] By adjusting the distance between the two limit frames 5, it can be adapted to the width or length of the processed wooden board, thereby assisting in restraining the board on both sides of the board, so that the feeding direction of the board is kept with high precision.

[0028] A fixed tooth 8 is fixed on the inner long side of the plate 3. The length direction of the fixed tooth 8 is consistent with the plate 3 and is perpendicular to the limit frame 5, so that the feeding and the toothing correspond.

[0029] A cutting tooth 9 matching with the fixed tooth 8 is arranged above the fixed tooth 8, a crossbeam 10 fixedly connected to the cutting tooth 9 is arranged on the top of the cutting tooth 9, a sliding sleeve 11 is arranged at both ends of the crossbeam 10, a sliding column 12 slidably connected to the sliding sleeve 11 is passed through the sliding sleeve 11, and the bottom end of the sliding column 12 is fixed on the frame structure 2, so as to guide the lifting of the crossbeam 10.

[0030] The two ends of the crossbeam 10 are respectively provided with an articulated seat 13, a pull rod 14 is rotatably connected in the articulated seat 13, a rotating sleeve 15 is fixed to the bottom end of the pull rod 14, and the axis of the rotating sleeve 15 is horizontally arranged, and a connecting shaft is rotatably installed on the support base 1 through a bearing seat, and eccentric wheels 16 are respectively fixed at both ends of the connecting shaft, the eccentric wheel 16 is arranged in the rotating sleeve 15, and the circumferential side of the eccentric wheel 16 is circumferentially rotatably connected to the inner ring of the rotating sleeve 15.

Based on the rotation of the eccentric wheel 16, the pull rod 14 is driven to swing up and down to drive the crossbeam 10 to rise and fall. In this way, the cutting teeth 9 are lifted and lowered, interlaced with the fixed teeth 8, and the plate is toothed.

[0032] The square frame structure 2 is also fixedly welded with a support frame 18 which is perpendicular to the fixed teeth 8 and extends horizontally. The support frame 18 is a door-type structure. The support frame 18 is located below the platen 3 and the fixed teeth 8. A positioning frame which can adjust the fixed position along its length is provided above the support frame 18. The positioning frame includes a vertical frame 19 and a bottom frame 20. One end of the bottom frame 20 is vertically connected and fixed to the bottom end of the vertical frame 19. The vertical frame 19 has an upright positioning end face 21 on the side close to the fixed teeth 8 through welding or one-piece forming and bending processing. The positioning end face 21 is used to position the front frame rod of the fed plate material, thereby positioning the tooth punching position, so that the position of each tooth punching operation can be accurately controlled. The top surface of the support frame 18 is provided with an adjustment groove 22, and the adjustment groove 22 is provided with a notch at the end of the support frame 18 away from the platform 3. The base frame 20 is penetrated by a stud bolt 23, and the stud bolt 23 penetrates the adjustment groove 22 to conveniently and quickly adjust the position and fix the position of the positioning frame, thereby flexibly adjusting the positioning of the tooth punching position.

At the same time, the amplitude of the board feeding is positioned by adjusting and setting the position of the positioning frame in advance, and the tooth punching position is calibrated. The tooth punching operation is driven by the eccentric wheel 16 to lift and cut, which is efficient and labor-saving with good cutting quality. Through this device and the above operation, the tooth punching operation can be carried out efficiently and labor-saving, and the tooth punching quality is good, the control accuracy is high, and high-quality tooth edges are obtained.
