The processing table 1 is provided with a return prevention mechanism on both sides. Structure 6, the anti-return mechanism 6 is used in conjunction with the pushing mechanism 4 to prevent the plate that has been pushed out from the bottom of the storage frame 2 from moving in the opposite direction. A cutting groove 7 is provided on the other side of the top of the processing table 1, and a cutting mechanism 8 is provided on one side of the bottom of the processing table 1. The cutting mechanism 8 is used in conjunction with the cutting groove 7. When the plate is pushed to the position of the cutting groove 7 by the pushing mechanism 4 at the top of the processing table 1, the cutting mechanism 8 can cut the plate at this time. A bridge frame 11 is bolted to the other side of the top of the processing table 1 and above the cutting groove 7. An electric telescopic rod 15 is installed on one side of the bridge frame 11 close to the through groove 5 through a support plate. The number of the electric telescopic rods 15 is two and they are symmetrically distributed. The output end of the electric telescopic rod 15 is bolted to a pressing plate 16.

[0028] The propulsion mechanism 4 includes a stepper motor 41, which is bolted to one side of the processing table 1 through a support plate, and the output shaft of the stepper motor 41 is bolted to a screw 42, and the other end of the stepper motor 41 is rotatably connected to the support plate through a bearing seat, and the support plate of the screw 42 is bolted to the bottom of the processing table 1, which can provide a supporting effect for the screw 42, and one side of the surface of the screw 42 is threadedly connected to a first screw sleeve 43, and the surface of the first screw sleeve 43 is bolted to a connecting frame 46, and the connecting frame 46 is designed as a Y-shaped structure, and both sides above the connecting frame 46 are slidably connected to the inner wall of the through groove 5. The top of the connecting frame 46 extends to the top of the processing table 1 through the through slot 5, and the top of the connecting frame 46 is bolted to the bottom of the support plate 3. When the stepping motor 41 provides power to drive the screw 42 to rotate, due to the sliding connection between the connecting frame 46 and the inner wall of the through slot 5, the first screw sleeve 43 can drive the support plate 3 to move at the bottom of the storage frame 2 through the connecting frame 46. When the support plate 3 moves, the groove on one side of it will push the bottom plate in the storage frame 2 from the bottom of the storage frame 2 to the other side of the top of the processing table 1, and in this process, the flat surface on the other side of the support plate 3 will The bottom of the storage frame 2 is in sliding contact, and the bottom of the storage frame 2 can be temporarily blocked to prevent the plate from continuing to fall. The other side of the surface of the screw 42 is threadedly connected with a second screw sleeve 45, and the surface of the second screw sleeve 45 is provided with a pushing component 44, and the pushing component 44 is used in conjunction with the through groove 5. When the screw 42 is rotating, the second screw sleeve 45 can drive the pushing component 44 on the surface of the screw 42, along the through groove 5 toward the bridge 11 through the cooperation of the pushing component 44 and the through groove 5. At this time, the pushing component 44 can push the plate on the top of the processing table 1 to the cutting groove 7 , the cutting mechanism 8 performs cutting processing on it, which can improve the adaptability of the device to different plate loading, reduce manual intervention and improve production efficiency. When the stepper motor 41 rotates in the reverse direction, the first screw sleeve 43 and the second screw sleeve 45 can respectively drive the support plate 3 and the pushing component 44 to move in the reverse direction to the initial position, and continue to push and deliver the next plate to be cut. In this process, the pushing component 44 is used in conjunction with the anti-return mechanism 6 to ensure that the plate can only be pushed from the bottom of the storage frame 2 to the processing table 1 without reverse sliding or retreating.

[0029] The pushing assembly 44 includes a sliding frame 441, which is fixedly connected to the surface of the second screw sleeve 45. There are two sliding frames 441, and they are both slidably connected to the inner wall of the through groove 5. One side of the inner wall of the sliding frame 441 is rotatably connected to a rotating shaft 442, and a push rod 443 is fixedly connected to the surface of the rotating shaft 442. One end of the push rod 443 is fixedly connected to a counterweight block 444. The counterweight of the counterweight block 444 can keep the push rod 443 in a stable tilted posture under normal conditions. The top of the tilted push rod 443 extends to the top of the processing table 1 through the through groove 5. The sliding frame 441 is slidably connected to the inner wall of the through groove 5. When the stepping motor 41 provides power, the second screw sleeve 45 can drive the push rod 443 to move along the through groove 5 toward the cutting groove 7 through the sliding frame 441. When the stepper motor 41 rotates in the reverse direction, the second screw sleeve 45 drives the push rod 443 to automatically return to the initial position through the sliding frame 441, and the push rod 443 rotates around the rotating shaft 442, so that the push rod 443 is in a relatively horizontal posture and slides in contact with the bottom surface of the plate, and the plate can be prevented from retreating to the bottom of the storage frame 2 by the anti-return mechanism 6 until the push rod 443 is moved back to the initial position. Under the action of the counterweight block 444, the push rod 443 can be quickly tilted, so as to continue to push and deliver the next plate to be cut, thereby effectively reducing manual intervention and improving the automation level of the device.

[0030] The anti-return mechanism 6 includes a mounting shell 61, which is bolted to the top of the processing table 1. A rotating column 62 is rotatably connected to one side of the inner wall of the mounting shell 61. A blocking rod 63 is fixedly connected to the surface of the rotating column 62. The blocking rod 63 is designed to be inclined. One end of the blocking rod 63 extends to the outside of the mounting shell 61. The blocking rod 63 is used in conjunction with the plate. A tension spring 64 is fixedly connected to one side of the inner wall of the mounting shell 61. The other end of the tension spring 64 is fixedly connected to one side of the blocking rod 63. When the propulsion mechanism 4 pushes the plate out from the bottom of the storage frame 2 through the support plate 3, the plate The two sides will slide in contact with the side surfaces of the baffle rod 63, so that the inclined end of the baffle rod 63 is squeezed by sliding, and the baffle rod 63 as a whole is in a relatively horizontal state, which will not affect the pushing and unloading of the plate. When the plate completely leaves the bottom of the storage frame 2, the baffle rod 63 can be quickly restored to the inclined state under the action of the tension spring 64, so that one end of the inclined baffle rod 63 is in contact with one side of the plate, ensuring that the plate can only be pushed forward to the processing table 1, thereby preventing the plate that has left the bottom of the storage frame 2 from reversing.

[0031] The cutting mechanism 8 includes a driving motor 81, which is bolted to one side of the processing table 1 through a support plate, and the output shaft of the driving motor 81 is bolted to a first screw rod 82, and the surface of the first screw rod 82 is rotatably connected to the support plate through a bearing, and the support plate of the first screw rod 82 is bolted to the bottom of the processing table 1, which can provide a stable support effect for the first screw rod 82, and the surface of the first screw rod 82 is threadedly connected to a first slider 83, and the top of the first slider 83 is slidably connected to the bottom of the processing table 1, and a cutting saw 84 is installed on one side of the first slider 83, and the cutting saw 84 includes a motor and a saw blade, and the motor of the cutting saw 84 is bolted to one side of the second slider 93, and the saw blade of the cutting saw 84 is bolted to the output shaft of its motor, and the motor of the cutting saw 84 drives the saw blade to rotate The plate can be cut and trimmed, the saw blade of the cutting saw 84 corresponds to the position of the cutting groove 7, and the saw blade of the cutting saw 84 extends to the top of the processing table 1 through the cutting groove 7. When the driving motor 81 provides power to drive the first screw rod 82 to rotate, the first slider 83 can drive the cutting saw 84 to move on the first screw rod 82 through the sliding connection between the top of the first slider 83 and the bottom of the processing table 1, so that the saw blade of the cutting saw 84 can move along the cutting groove 7, so that the plate located at the cutting groove 7 can be cut. The first screw rod 82 is used in conjunction with the linkage mechanism 9 to drive the dust collection shell 18 to move synchronously during the process of cutting the plate, so that the dust collection shell 18 can promptly absorb and treat the dust and wood chips generated during cutting.

[0032] The linkage mechanism 9 includes a second screw rod 92, which is located on one side of the bridge frame 11. One end and the surface of the second screw rod 92 are rotatably connected to a support plate through a bearing. The support plate of the second screw rod 92 is bolted to one side of the bridge frame 11, which can provide a stable support effect for the second screw rod 92. A synchronous pulley component 91 is provided at one end of the second screw rod 92. The driving motor 81 includes two gears and a transmission toothed belt. One gear of the synchronous pulley component 91 is fixedly connected to one end of the second screw rod 92, and the other gear of the synchronous pulley component 91 is fixedly connected to one end of the second screw rod 92, and the transmission toothed belt of the synchronous pulley component 91 is meshed with the two gears. When the first screw rod 82 rotates, power can be transmitted to the second screw rod 92 through the synchronous pulley component 91 so that it can be synchronously The second slider 93 is threadedly connected to the surface of the second screw rod 92, and one side of the second slider 93 extends to the inside of the bridge frame 11 through the sliding groove 17. The surface of the second slider 93 is slidably connected to the inner wall of the sliding groove 17, and one side of the second slider 93 is bolted to the surface of the dust collection shell 18. When the cutting mechanism 8 cuts the plate at the cutting groove 7, the synchronous pulley component 91 can synchronously transmit the rotational power of the first screw rod 82 to the second screw rod 92 to rotate it, and under the sliding restriction of the second slider 93 and the sliding groove 17, the second slider 93 can drive the dust collection shell 18 to move in the inner cavity of the bridge frame 11, thereby automatically and timely sucking in and collecting the dust and wood chips generated during cutting, so as to keep the surrounding working environment clean and reduce the impact on the operator.

[0033] It is worth noting that the vacuum cleaner 10 and the cutting saw 84 proposed in this technical solution are both existing technologies, and their working principles and beneficial effects when used are not described in detail here.

[0034] Working principle: First, the stacked plates are placed inside the storage frame 2 by a forklift, and then the stepper motor 41 is started to drive the screw 42 to rotate, so that the first screw sleeve 43 drives the support plate 3 to move at the bottom of the storage frame 2 through the connecting frame 46, so that the groove of the support plate 3 pushes the plates at the bottom of the storage frame 2 to its outside. At this time, the two sides of the plates will contact and slide with the side surfaces of the blocking rod 63, so that the blocking rod 63 is squeezed in a horizontal state, and when the plates completely leave the storage frame 2, the blocking rod 63 can be pressed under the action of the tension spring 64. The rod 63 is restored to an inclined state so that one end thereof abuts against one side of the plate, which ensures that the plate can only be pushed forward. Then, the second screw sleeve 45 on the surface of the screw rod 42 drives the push rod 443 to abut against one side of the plate through the sliding frame 441, and the plate is continuously pushed to the cutting groove 7 by the push rod 443 to deliver the material. Then, the driving motor 81, the cutting saw 84 and the vacuum cleaner 10 are started, and the driving motor 81 drives the first screw rod 82 to rotate, so that the first sliding block 83 drives the cutting saw 84 to move along the cutting groove 7 to cut the plate. The cutting process is carried out. During this process, the power of the first screw rod 82 can be transmitted to the second screw rod 92 through the synchronous pulley component 91 to make it rotate, so that the second slider 93 can drive the dust collection shell 18 to move synchronously in the bridge frame 11, thereby automatically and timely sucking in the dust and wood chips generated during cutting, and transporting them to the dust collector 10 for collection through the hose 13, so that the surrounding working environment can be kept clean. When it is necessary to continue to deliver the plates in the storage frame 2, first reverse the stepper motor 41 to make the connecting frame 46 and the pushing assembly 44 move in the opposite direction to the initial position. During this process, the push rod 443 will rotate around the rotating shaft 442, so that the push rod 443 becomes horizontal and slides in contact with the bottom surface of the plate until the push rod 443 is moved back to the initial position. Under the action of the counterweight block 444, the push rod 443 can be quickly tilted, so as to continue to push and deliver the next plate to be cut. Such reciprocating operation can effectively improve the automation level of the plate delivery of this device and improve the cutting efficiency of the plate.
