[0012] Beneficial Effects
[0013] The present invention provides a wood veneer panel blanking device, which has the following beneficial effects compared with the prior art:
[0014] 1. When one end of the wood veneer panel is pushed into the groove of the connecting frame on the conveyor belt, and the wood veneer panel is pushed for a period of time to be pressed between the two push cylinders, the user then starts the motor connected to the transmission shaft. At this time, the gears A fixedly connected at both ends of the transmission shaft rotate synchronously, so that the gear A drives the gear ring A meshing with it to start to rotate synchronously at a uniform speed, and drives the slip ring fixedly connected with it to rotate synchronously, so that the slip ring starts to drive the wood veneer panel to gradually rotate to a vertical state. At this time, the slip ring starts to drive the transmission gear set thereon to rotate synchronously, so that the transmission gear starts to roll on it under the cooperation of the gear ring meshing with it, so that the shaft fixedly connected at the axis of the transmission gear starts to rotate synchronously. At this time, the gear fixedly connected at the top of the shaft starts to rotate synchronously, and the two gears meshing with each other rotate synchronously. At this time, the two push cylinders start to rotate synchronously, so that in the process of the wood veneer panel being rotated to a vertical state, the push cylinders cooperate with each other to push the wood veneer panel and push it between the other slip rings. When the wood veneer panel is turned to a vertical state, one end of the wood veneer panel is pushed out of the slip ring;
[0015] 2. When the transmission shaft starts to rotate, the worm fixed on it rotates synchronously, thereby causing the worm wheel meshing with it to rotate synchronously. Since the transmission of the worm gear has a deceleration effect, the lead screw fixed at the axis of the worm wheel can rotate at a speed slower than that of the transmission shaft, so that the lead screw begins to drive the slider threadedly connected to it. At this time, the plate frame fixedly connected to the slider begins to move linearly along the connection with the limit rod, thereby pushing the first row of partitions formed by the two rows of positioning rods to the center axis of the partition ring. At the same time, one end of the wooden veneer panel between the two connecting frames is pushed out of the connecting frame and is between the two positioning rods. At this time, the wooden veneer panel is in a vertical state. Subsequently, the user starts the motor connected to the guide rod, so that the guide rod drives the sprocket fixed on it to start rotating. At this time The sprocket drives the chain meshed with it to start rotating, so that multiple sprockets start to rotate synchronously with the cooperation of the chains meshed with it, and then multiple conveying cylinders start to rotate synchronously at this time, so as to start to transport the wood veneer panel thereon and pull the wood veneer panel out of the connecting frame. When the wood veneer panel is separated from the connecting frame, multiple conveying cylinders cooperate with each other to push the wood veneer panel to contact with the board frame; then the user can start the motor connected to the transmission shaft again, so that the connecting frame starts to continue to rotate until it is parallel to the frame, so as to adjust the position of the wood veneer panel in a cycle. At the same time, during the rotation of the connecting frame, the board frame can be synchronously linearly moved, so that the partition with the wood veneer panel placed thereon is pushed out to a position facing the central axis of the partition ring, so that multiple wood veneer panels can be pushed to the board frame in sequence for storage;
[0016] 3. When multiple guide rods start to rotate, the pulleys fixed thereon start to rotate, so that pulley B starts to rotate synchronously with the pulley under the cooperation of the belt meshing with it. At this time, the shaft rod fixedly connected at the axis of pulley B starts to rotate, and drives the cam fixed thereon to rotate synchronously, so that the cam gradually begins to contact the clamping frame during the rotation process, and pushes it to perform linear movement along the connection with the slide rod. At this time, the clamping frame begins to stretch the spring fixedly connected thereto, so that it is in a stretched state, so that the spring can rebound and reset after the cam stops supporting the spring. When the center axis of the cam is facing the clamping frame, the clamping frame pushes the guide cylinder rotatably connected thereon to press against the wood veneer panel, so that the wood veneer panel can be tightly attached to the conveying cylinder, so that the conveying cylinder can effectively convey the wood veneer panel to avoid the wood veneer panel slipping on it and being unable to be pushed. Then the slide rod continues to rotate, so that the guide cylinder periodically contacts the wood veneer panel to avoid long-term pressure on the wood veneer panel, which causes the wood veneer panel to be deformed under force.

Since the transmission of the worm gear has a deceleration effect, the lead screw 303 fixedly connected at the axis of the worm wheel 302 can rotate at a speed slower than that of the transmission shaft 2004, so that the lead screw 303 begins to drive the slider 304 threadedly connected thereto. At this time, the plate frame 305 fixedly connected to the slider 304 begins to perform linear motion along the connection between it and the limit rod 306, thereby pushing the first row of partitions formed by the two rows of positioning rods 307 to the center axis of the partition ring 201.
