After that, the second cylinder 14 can be started to make the push plate 15 below it stay at a height that can push the core plate, and then the steel frame 8 is started, and the transmission chain plate 11 drags the lug 13, and finally the core plate will be stably moved to the position of the partition plate 22 through the push plate 15. After staying at a suitable position, the user can continue to control the operation of the third cylinder. As the two groups of partition plates 22 slowly move to both ends, the core plate will eventually fall on the surface of the first cylinder 6 set in advance, and then the subsequent lifting, stacking and stacking operations can be continued; The inner surface of the enclosure 23 is fixedly connected with a cushion shell 24, and the inner surface of the enclosure 23 is equidistantly fixedly connected with a cushion shaft 25, and the surface of the cushion shaft 25 is fixedly connected with a back-up seat 26, and the surface of the back-up seat 26 is sleeved with a towing rack 27.

After the core plate is operated by the first cylinder 6 and starts to be lifted, it will continuously touch the towing rack 27, causing it to The surface of the back-up seat 26 is turned over and reset. As the core plates are stacked one by one, the greater the pressure on the back-up seat 26, the lower the reset degree of the bracket 27, until the core plates are stacked and pressed together. This stacking method can effectively reduce the crushing rate. At this time, as the disc cam 36 rotates, the ring cap on its surface will drag the swing rod 70, and make it move with the swing member 67 using the slot 71. As the pad 65 contacts the disc cam 36, the tooth head 72 will eventually drive the tooth plate 73 to rotate periodically, and the second screw rod 74 on its surface will cooperate with the screw sleeve 32 to move. Finally, under the action of the embedded rod 29, the entire gear rod 30 moves. Once the bracket 27 at the bottom no longer blocks the core plate, the material can be unloaded. The surface of the positioning seat 34 is rotatably connected with a connecting shaft 35, and both ends of the connecting shaft 35 are connected with a disc cam 36. A surrounding groove 37 is provided on the surface of one end of the disc cam 36 near the side edge, and a connecting groove 38 is provided on the surface of the disc cam 36 located inside the surrounding groove 37. The connecting groove 38 is fixedly connected to the connecting shaft 35. A vertical plate 39 is symmetrically fixedly connected to the top surface of the positioning frame 33 near one end edge. A movable groove 40 is provided on the side surface of the vertical plate 39, a clamping groove 41 is provided on the surface of the movable groove 40, a clamping piece 42 is embedded and connected on the surface of the movable groove 40, a protrusion 43 is fixedly connected to a side surface of the clamping piece 42, the protrusion 43 is embedded and connected with the clamping groove 41, a top section 44 is fixedly connected to the top surface of the clamping piece 42, a connecting rod 46 is sleeved and connected to the surface of the top section 44, an insertion rod 45 is fixedly connected to the side surface of the clamping piece 42, and the insertion rod 45 is embedded and connected with the surrounding groove 37, a connecting plate 47 is provided at one end of the vertical plate 39, a connecting groove 48 is provided on the surface of the connecting plate 47, and a connecting rod 49 is fixedly installed near the middle of the top surface of the connecting plate 47; The surface of the connecting rod 49 is sleeved with an annular sleeve 50, and the side surface of the annular sleeve 50 is symmetrically fixedly connected with a connecting piece 51, and the side surface of the connecting piece 51 is fixedly connected with an extension rod 52, one end of the connecting piece 51 is fixedly connected with an anti-slip rod 53, and one end of the extension rod 52 is fixedly connected with a slider 54, and a clamping rod 55 is provided on the surface of the extension rod 52, and the connecting rod 46 is sleeved with the extension rod 52, and the surface of the clamping rod 55 is located at the upper end of the slider 54 and is sleeved with a gasket 56, and the surface of the clamping rod 55 is located on both sides of the gasket 56 and is sleeved with a sleeve cap 58, and the clamping rod 55 is located at the upper end of the slider 54 ... The bottom surface of the core plate is fixedly connected with an anti-drop cap 57, one of the caps 58 is fixedly connected with a connecting piece 59, and the side surface of the connecting piece 59 is symmetrically welded and fixed with a support plate 60, one of the support plates 60 is rotatably connected with an arc sleeve 62, and the bottom surface of the other support plate 60 is fixedly connected with an elastic guide wheel 61. During the process of stacking the core plate, the user can control the motor to operate, and the connecting shaft 35 will make the two sets of disc cams 36 rotate synchronously. The two sets of disc cams 36 are reversed, which will result in only one side rotating at the same time. The baffle is unfolded to avoid interference. During the rotation of the disc cam 36, whenever the part of the surrounding groove 37 away from the axis approaches the insertion rod 45, it will drive it to move along the movable groove 40. That is, at this time, the corresponding baffle will gradually move from one side to the middle position, and then wait for the insertion rod 45 to pass the surrounding groove 37 farthest from the axis. The corresponding baffle will start to reset and move to one side again. During the movement of the disc cam 36, the clamping rod 55 on the surface of the slider 54 will move along the connecting groove under the restriction of the anti-drop cap 57. The connecting groove 48 moves, first through the straight section of the connecting groove 48, and then with the linkage of the connecting rod 46, the clamping rod 55 will enter the arc section of the connecting groove 48. Since the connecting piece 51 rotates around the connecting rod 49, the slider 54 will slowly move along the connecting piece 51 toward the connecting rod 49 with the interference of the arc section. The cap 58 that is sleeved on the surface of the anti-slip rod 53 and the arc sleeve 62 on the side surface will slowly rotate with the movement of the slider 54, causing the two baffles that were originally close to each other to slowly unfold, and finally the two sets of elastic guide wheels 61 to correct the deviation of the stacked core board.

[0020] Working principle of the present invention: according to the needs of material unloading, the user can control the operation of the first motor 2, and after the output end thereof drives the first screw rod 3 to rotate, in cooperation with the limiting effect of the vertical rod 4, the entire carrier plate 5 will drive the first cylinder 6 to stay at a suitable height to meet the height requirements in the processing process. During the unloading and stacking process of the plywood core board, it can be placed on the surface of the conveyor rack 16 in an orderly manner through an external machine, and then the conveyor rack 16 can be controlled to stay at a suitable position by the operation controller. After that, the second cylinder 14 can be started to make the push plate 15 below it stay at a height capable of pushing the core board, and then the steel frame 8 is started, and the transmission chain plate 11 is used to drag the support ear 13, and finally the core board will be stably moved toward the partition 22 through the push plate 15. Position, after staying in the appropriate position, the user can continue to control the operation of the third cylinder, as the two groups of partitions 22 slowly move to both ends, the core plate will eventually fall on the surface of the first cylinder 6 set in advance, and then the subsequent lifting, stacking and stacking operations can be continued. After the core plate begins to be lifted by the operation of the first cylinder 6, it will continue to touch the trailer 27, causing it to flip and reset on the surface of the back-force seat 26. As the core plates are stacked one by one, the greater the pressure on the back-force seat 26, the lower the reset degree of the trailer 27, until the core plates are stacked layer by layer and pressed against each other. This stacking and stacking method can effectively reduce the crushing rate. At this time, as the disc cam 36 rotates, the ring cap on its surface will drag the rocker arm 70 and make it use the groove 71 to match The swinging member 67 moves, and as the pad 65 contacts the disc cam 36, the tooth head 72 will eventually drive the toothed disc 73 to rotate periodically, and the second screw rod 74 on its surface will cooperate with the movement of the screw sleeve 32, and finally under the action of the embedded rod 29, the entire gear rod 30 moves. Once the bottom trailer 27 no longer blocks the core plate, the unloading can be completed. During the unloading and stacking of the core plate, in order to stabilize the stacking, the user can control the operation of the motor, and the connecting shaft 35 will make the two sets of disc cams 36 rotate synchronously. The two sets of disc cams 36 are set upside down, which will result in only one side of the baffle being unfolded at the same time to avoid interference. During the rotation of the disc cam 36, whenever the part of the surrounding groove 37 away from the axis leans against the insertion rod When the disc cam 36 moves, the clamping rod 55 on the surface of the slider 54 will move along the connecting groove 48 under the restriction of the anti-slip cap 57, first through the straight section of the connecting groove 48, and then with the linkage of the connecting rod 46, the clamping rod 55 will enter the arc section of the connecting groove 48. Because the connecting piece 51 rotates around the connecting rod 49, the slider 54 will slowly move toward the connecting rod 49 along the connecting piece 51 with the interference of the arc section, and the sleeve cap 58 on the surface of the anti-slip rod 53 will move along the connecting piece 51.The arc-shaped sleeve 62 on the side surface will slowly rotate with the movement of the slider 54, causing the two baffles that were originally close together to slowly expand, and finally allowing the two sets of elastic guide wheels 61 to correct the deviation of the stacked core board.
