[0024] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Figure 1-Figure 8 A four-head edge saw type cutting machine for wooden doors, comprising a base 1, a combined rail 2, a bearing platform 3 and a cutting head 4, wherein the combined rail 2 is arranged on the base 1, and the combined rail 2 comprises a first rail group 21 and a second rail group 22, the first rail group 21 comprises a fixed rail and a first movable rail 211, the fixed rail is arranged on the base 1, the first movable rail 211 is guided and slidably arranged on the base 1, and a hydraulic cylinder is provided to control its forward and backward sliding, wherein when the first movable rail 211 is in an extended state, the first rail group 21 is a complete rail group, the second rail group 22 is perpendicular to the first rail group 21, the second rail group 22 comprises a double fixed rail 222 and a second movable rail 221, the double fixed rail 222 is fixedly arranged on the base 1, the second movable rail 221 is guided and slidably arranged on the base 1, and a hydraulic cylinder is provided to control its forward and backward movement.

[0025] The front end of the first movable rail 211 is provided with an open long slot 212, and the slot width is the same as the diameter of the second movable rail 221. When the supporting platform 3 moves to the end of the first rail group 21, the passage of the supporting platform 3 to the second rail group 22 is blocked by the first movable rail 211. At this time, the supporting platform 3 presses the pressure touch switch at the end of the first rail group 21, and the control hydraulic cylinder starts to work, so that the first movable rail 211 retracts, and at the same time controls the second movable rail 221 to extend forward. Since the first movable rail 211 and the second movable rail 221 move at the same time, the supporting platform 3 is always supported by the rail. After all are moved into place, the first movable rail 211 leaves the blocking position, and the supporting platform 3 can enter the second rail group 22.

[0026] A wire winding device 31 is provided on the supporting platform 3, and the wire winding device 31 includes a motor 311 and a wire winding drum 312. The motor 311 is arranged in the supporting platform 3, and the wire winding drum 312 is arranged on the motor 311. The rotation of the motor 311 can cause the wire winding drum 312 to rotate. The side of the supporting platform 3 is also provided with a limiting slide groove 32 in the same direction as the second track group 22. A first sliding block 33 is slidably arranged in the limiting slide groove 32. The rear end of the first sliding block 33 touches one end of a first elastic member 331, and the other end touches the base 1 at the end of the first track group 21. The first elastic member 331 is provided with an elastic pull rope 332, and its two ends are respectively arranged on the rear end of the first sliding block 33 and the base 1 at the end of the first track group 21. The elastic pull rope 332 is used to support the first elastic member 331 to prevent the first elastic member 331 from falling.

[0027] In the initial state, the support platform 3 contacts the front end of the first track set 21 under the action of the first elastic member 331 , and the elastic pull rope 332 is in a stretched state.

[0028] The upper end track of the double fixed track 222 is the track of the carrier platform 3, and the second sliding block 23 is set on the lower end track for guiding sliding, and one end of the second elastic member 232 is set on the rear end surface of the second sliding block 23, and the other end is set on the base 1 at the end of the second track group 22. A guide wheel 231 is rotatably set on the second sliding block 23, wherein the winding drum 312 on the winding device 31 is set on one end of the pull rope 24, and the other end is fixed on the base 1 at the end of the second track group 22 by passing around the guide wheel 231, and a second locking member 25 is set on the double fixed track 222, and the second locking member 25 is an electric latch, and a latch hole is opened on the second sliding block 23.

[0029] In the initial state, the second sliding block 23 is located at the front end of the second track set 22 under the action of the second elastic member 232. At this time, the electric latch of the second locking member 25 is inserted into the latch hole on the second sliding block 23, thereby locking the second sliding block 23.

[0030] A locking protrusion 333 is provided on the first sliding block 33, and a locking hole is horizontally opened on the locking protrusion 333. A first locking piece 26 is provided at the end of the first track group 21. The first locking piece 26 is provided with an opening groove 261. The first locking piece 26 includes an electric latch. When the supporting platform 3 contacts the end of the first track group 21, the locking protrusion 333 is immersed in the opening groove 261, and the electric latch is directly inserted into the locking hole of the locking protrusion 333, thereby locking the first sliding block 33.

[0031] The motor 311 drives the cable reel 312 to rotate, tightens the pull rope 24, and the bearing platform 3 moves backward along the first track group 21 under the action of the pulling force, and drives the first sliding block 33 to move backward together during the backward movement, compressing the first elastic member 331. When the bearing platform 3 touches the end of the first track group 21, the pressure switch is pressed. The motor 311 is a brake motor, thereby controlling the motor 311 to stop. At the same time, the locking protrusion 333 is immersed in the opening groove 261, and the electric latch is directly inserted into the locking hole of the locking protrusion 333, thereby locking the first sliding block 33 and controlling the hydraulic cylinder to act. The first movable track 211 and the second movable track 221 move simultaneously, the passage opening of the second track group 22 is opened, and the track of the first track group 21 to the second track group 22 is switched. At this time, the bearing platform 3 can slide on the second track group 22, and the second locking member 25 is unlocked, so that the second sliding block 23 can slide on the double fixed track 222.

[0032] The cutting head 4 includes a first cutting group 41 and a second cutting group 42. Each cutting group is provided with two cutting heads, and the axes of the two cutting heads are the same. When the board surface passes through, both sides of the board surface can be cut. The first cutting group 41 is arranged along the direction of the first track group 21, and the second cutting group 42 is arranged along the direction of the second track group 22.

[0033] A locking device is provided on the supporting platform 3, and the locking device is a suction cup. When the robot or the circulation device places the wooden board on the supporting platform 3, the locking device can adsorb the wooden board on the supporting platform 3. When the supporting platform 3 moves along the direction of the first track 21, the first cutting group 41 completes the cutting of both sides of the wooden board.

[0034] After the track switching is completed and the second locking piece 25 is unlocked, the motor 311 is started, and the pull rope 24 is wound again. The supporting platform 3 slides on the second track group 22. During the movement, the second cutting group 42 completes the cutting of the other two sides of the wooden board, and the cutting tasks are performed on both sides at the same time, so the parallelism of the two sides is consistent. At the same time, the first track group 21 is perpendicular to the second track group 22, so each corner of the cut wooden board is a right angle, ensuring the cutting quality.

[0035] When the supporting platform 3 slides along the second track group 22, the first sliding block 33 on the supporting platform 3 is locked on the first locking piece 26 at the end of the first track group 21. After the supporting platform 3 moves to the end of the second track group 22, the entire cutting operation is completed and the motor 311 stops. At this time, the manipulator or the circulation device moves the cut wooden board away from the supporting platform 3. After the moving away, the motor 311 is powered off. Under the action of the second elastic piece 232, the supporting platform 3 slides forward along the second track group 22 and touches the front end of the second track group 22. During the forward sliding process of the supporting platform 3, the limiting slide groove 32 on the supporting platform 3 slides back into the first sliding block 33 locked on the first track group 21, thereby locking the movement of the first sliding block 33 and the supporting platform 3 in the direction of the first track group 21.

[0036] When the supporting platform 3 touches the front end of the second track group 22, the pressure switch is pressed, thereby controlling the hydraulic cylinder to start working, so that the first movable track 211 is extended, and the second movable track 221 is controlled to retract backward, and at the same time, the second locking member 25 is controlled to be locked and the first locking member 26 is controlled to be unlocked. The second locking member 25 is locked to lock the second sliding block 23, and the first locking member 26 is unlocked to unlock the first sliding block 33. At this time, the track returns to its initial state. Therefore, the supporting platform 3 slides forward under the action of the first elastic member 331 and touches the front end of the first track group 21. At this point, the supporting platform 3 is reset.

[0037] Its working principle or usage is as follows:

[0038] In the initial state, the wooden board is placed on the supporting platform 3 by a robot or a circulation device, and the locking device on the supporting platform 3 is started to adsorb the wooden board on the supporting platform 3. At this time, the motor 311 on the supporting platform 3 is started, and the pull rope 24 is tightened, thereby pulling the supporting platform 3 to move along the first track group 21. When the motor 311 is started, the first cutting group 41 is started. Therefore, in the process of the supporting platform 3 moving along the first track group 21, the cutting operation on both sides of the wooden board is completed. When the supporting platform 3 moves to the end of the first track group 21, it touches the pressure touch switch at the end, so that the motor 311 is braked.

[0039] At the same time, the hydraulic cylinder is controlled to start working, so that the first moving rail 211 is retracted, and the second moving rail 221 is controlled to extend forward. After all the movements are in place, the first moving rail 211 leaves the blocking position, and the supporting platform 3 can enter the second rail group 22. When the pressure switch is pressed, the second locking member 25 is controlled to be unlocked and the first locking member 26 is locked. The first locking member 26 locks the first sliding block 33 at the end position of the first rail group 21. The second locking member 25 is unlocked to allow the second sliding block 23 to move. At this time, the motor 311 continues to rotate and continues to tighten the pull rope 24, thereby driving the second sliding block 23 to move along the second rail group 22, and the supporting platform 3 moves laterally out of the first sliding block 33. When the motor 311 continues to rotate, the second cutting group 42 is started, and the cutting operation on the other two sides of the wooden board is completed while the supporting platform 3 is moving along the second rail group 22.

[0040] When the supporting platform 3 moves to the end of the second track group 22, the motor 311 brakes and the locking device is released. After the manipulator or the transfer device removes the wooden board from the supporting platform 3, the motor 311 is powered off, so the brake device on the motor 311 stops working. As a result, the tensioning force and locking force on the pull rope 24 disappear. Under the action of the second elastic member 232, the supporting platform 3 first moves forward along the second track group 22 and touches the front end of the second track group 22, pressing the pressure switch, thereby controlling the hydraulic cylinder to start working, so that the first moving track 211 is extended, and the second moving track 221 is controlled to retract backward, and the track returns to its initial state.

[0041] At the same time, the second locking member 25 is controlled to lock and the first locking member 26 is unlocked. The second locking member 25 is locked to lock the second sliding block 23, and the first locking member 26 is unlocked to unlock the first sliding block 33. Therefore, the supporting platform 3 slides forward under the action of the first elastic member 331 and touches the front end of the first rail group 21. At this point, the supporting platform 3 is reset.
