The vertical driving device is a lead screw mounting seat 37 fixed on the vertical supporting seat 31, a vertical lead screw 38 is mounted in the lead screw mounting seat 37, the vertical lead screw 38 is connected with a vertical driving motor 39, and correspondingly, a lead screw nut is mounted on the vertical sliding table and is in threaded connection with the vertical lead screw 38.

The vertical driving motor 39 is a servo motor or a stepping motor and is connected with the main control system.

The longitudinal driving device is a pneumatic cylinder 412 which is arranged between the vertical sliding table 32 and the longitudinal sliding table 33 and is driven longitudinally.

The tooth opening knife 36 is also coated with a dust hood 1 in a rotary mode, the dust hood 1 is communicated with an air suction pipe 2 arranged at the top of the knife shaft seat 35, and the dust hood 1 rotates under the action of the reversing power device to force the opening end of the dust hood 1 to face to one side to be cut and processed.

The reversing power device is a gear 3 arranged on a rotating shaft of the dust hood 1, and correspondingly: the cutter shaft seat is provided with a rack 4 which is meshed with the gear 3, and the rack 4 is connected with a reversing cylinder 5.

The glue coating mechanism 6 comprises a glue coating plate 61, glue coating teeth 62 consistent with the shape of the plate tooth are arranged on the end face of the glue coating plate 61, and glue supplying channels are arranged inside the glue coating teeth 62 and connected with the glue supplying mechanism.

The working principle is as follows: as shown in fig. 1 and 8, the mechanism in the present application is installed in the middle of the dynamic pressure docking mechanism 7 and the constant pressure docking mechanism 8 for use, when in operation, the spindle motor drives the tooth opening knife 36 to rotate at a high speed, the vertical driving device drives the spindle motor to move downward, and the tooth opening knife 36 first cuts the plate conveyed by the dynamic pressure docking mechanism 7. After the cutting is finished, the air cylinder 412 is longitudinally driven to drive the central sliding table to move to a tooth position, the constant pressure butt joint mechanism 8 reversely pushes the plate backwards to enter the motion track of the slotting cutter, the vertical driving device drives the spindle motor to move upwards, the slotting cutter reversely cuts the plate at the end of the constant pressure butt joint mechanism 8, and an adhesive is coated on the slotting cutter. After the cutting is finished, the vertical sliding table and the longitudinal sliding table reset, so that the slotting cutter is separated from the plate. Because the teeth of the front plate and the rear plate are staggered, the dynamic pressure butting mechanism 7 and the constant pressure butting mechanism 8 can drive the plates on the dynamic pressure butting mechanism to move relatively, and the teeth joint of the plates is realized.

Wherein, it is required to be noted that: the feed amount of the slotting cutter needs to be accurately controlled during vertical movement, so that the vertical driving device is a lead screw mounting seat 37 fixed on a vertical supporting seat 31, a vertical lead screw 38 is mounted in the lead screw mounting seat 37, the vertical lead screw 38 is connected with a vertical driving motor 39, and correspondingly, a lead screw nut is mounted on a vertical sliding table and is in threaded connection with the vertical lead screw 38. The vertical driving motor 39 may be a stepping motor or a servo motor, and its rotation speed is precisely controlled to convert its rotation motion into an up-and-down linear motion of the spindle motor. The longitudinal movement of the spindle motor only needs to drive the slotting tool to displace by one tooth position, so the longitudinal driving device in this case is a longitudinal driving pneumatic cylinder 412 arranged between the vertical sliding table 32 and the longitudinal sliding table 33. The longitudinal driving pneumatic cylinder 412 is matched with the limiting blocks arranged at the two ends of the longitudinal sliding table 33, so that the two limit positions of the slotting cutter can work, the operation is reliable, stable and efficient, and the production cost is lower.

Further: in order to collect the wood cuttings in the cutting process, the tooth cutter 36 is further coated with a dust hood 1 in a rotary manner, the dust hood 1 is in a semicircular opening shape, the dust hood 1 is communicated with an air suction pipe 2 arranged at the top of the cutter shaft seat 35, and the dust hood 1 rotates under the action of a reversing power device to force the opening end of the dust hood 1 to face one side to be cut and processed. If when processing the panel of dynamic pressure docking mechanism one side, move the open end of suction hood to this side interface of orientation, under the negative pressure effect of aspiration channel, and the suction hood to the semi-enclosure effect of opening the serrated knife, can clean the wood cutting in the cutting process, avoid dust and wood to escape outside and influence the clean environment. When the slotting cutter processes one side of the constant-pressure butt-joint mechanism, the reversing cylinder 5 drives the rack 4 to do linear motion, so that the gear 3 meshed with the rack is driven to rotate, the gear rotates to drive the dust hood to rotate for reversing, and the open end of the dust hood is forced to face one side of the constant-pressure butt-joint mechanism. Therefore, compared with the prior art, the structure in the scheme can complete the comb tooth processing of two plates in one-time action process, and when the butt joint mechanism is matched for use, the comb tooth can be realized, the butt joint can be completed at one time, so that the production efficiency can be greatly improved, the dead time of the spindle motor is reduced, the energy consumption is reduced, and the structure can be widely popularized and used.
