[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a waste sorting and recycling device for building materials, including a base plate 1, a lifting structure 3 on the base plate 1, and a sorting structure 2 on the lifting structure 3;

[0024] The sorting structure 2 includes a fixed frame 201, a tilting plate 202, a first motor 203, a crank 204, a connecting rod 205, a first conveyor belt 206, a feeding conveyor belt 207, a support frame 208, a waste conveyor belt 209, a second conveyor belt 210, and a lifting plate 211. The fixed frame 201 is mounted on the lifting plate 211, the tilting plate 202 is movably mounted on the fixed frame 201, the first motor 203 is mounted on the fixed frame 201, the crank 204 is mounted on the drive end of the first motor 203, and the connecting rod 205... The connecting rod 205 is movably connected to the tilting plate 202 and mounted on the crank 204. The first conveyor belt 206 is mounted on the tilting plate 202, the feeding conveyor belt 207 is mounted on the lifting plate 211, the support frame 208 is mounted on the lifting plate 211, the waste conveyor belt 209 is mounted on the support frame 208, and the second conveyor belt 210 is mounted on the support frame 208. When sorting of the boards is required, the semi-finished boards and waste boards are continuously fed in at intervals via the feeding conveyor belt 207. When the semi-finished boards arrive at the first conveyor belt 206, the system keeps the first conveyor belt 206 in a horizontal conveying state and smoothly transfers them to the second conveyor belt 210, entering the qualified product collection process. When the waste sheet enters the first conveyor belt 206, the first motor 203 starts, driving the crank 204 to rotate. This, through the connecting rod 205, pushes the tilting plate 202 to rotate around the fixed frame 201 by a certain angle, thereby changing the end angle of the first conveyor belt 206 so that it aligns with the waste conveyor belt 209. The waste sheet then slides into the waste conveyor belt 209 under the influence of gravity and the conveyor belt, achieving automatic sorting and realizing continuous, efficient, and reliable sorting operations.

[0025] Furthermore, the base plate 1 is provided with support legs, and the fixed frame 201 is provided with reinforcing ribs. The support legs make the base plate 1 more stable. Through reasonable layout design, the support legs effectively increase the contact area and friction between the base plate 1 and the ground, significantly improving the overall stability of the equipment during operation, preventing displacement or shaking caused by external forces or internal moving parts, and ensuring the smooth operation of sorting. The reinforcing ribs increase the strength of the fixed frame 201. Through scientific topology optimization design, the reinforcing ribs are arranged in the key stress areas of the fixed frame 201 by welding or integral molding, which can effectively improve its bending and torsional stiffness, suppress structural deformation and vibration caused by the movement of the flip plate 202 and load changes, and ensure the long-term operating accuracy and reliability of the sorting mechanism under frequent start-stop and load conditions.

[0026] Furthermore, the first motor 203 is fixed to the fixed frame 201 by bolts. The tilting plate 202 is adapted to the fixed frame 201. The first motor 203, fixed by bolts, is easy to install and remove on the fixed frame 201. This connection method not only provides the motor with a stable installation rigidity, effectively resisting the periodic vibration and torque reaction force generated when the crank 204 and connecting rod 205 mechanism is working, but also facilitates the quick alignment adjustment, maintenance or replacement of the motor, significantly improving the maintainability of the transmission components and the long-term reliability of the system. The adapted tilting plate 202 rotates stably on the fixed frame 201. This mating structure, through strict tolerance design, appropriate surface treatment and lubrication, ensures that the rotation of the tilting plate 202 on the fixed frame 201 has low friction and no shaking. It can accurately respond to the drive of the connecting rod 205 mechanism, realize the stable and controllable adjustment of the tilt angle of the first conveyor belt 206, and ensure the accuracy and smoothness of the sorting action.

[0027] Furthermore, the lifting structure 3 includes a sleeve 301, a moving rod 302, a second motor 303, a placement frame 304, a moving rack 305, a mounting frame 306, a rotating shaft 307, a rotating gear 308, a rotating gear 309, a connecting frame 310, and a transmission gear 311. The sleeve 301 is mounted on the base plate 1. The moving rod 302 is movably mounted on the sleeve 301 and is connected to the lifting plate 211. The placement frame 304 is mounted on the base plate 1. The moving rack 305... A rack 305 is movably mounted on the placement frame 304 and connected to the lifting plate 211. A mounting frame 306 is mounted on the base plate 1. A rotating shaft 307 is movably mounted on the mounting frame 306. A rotating gear 308 is mounted on the rotating shaft 307 and meshes with the moving rack 305. A rotating gear 309 is mounted on the rotating shaft 307. A connecting frame 310 is mounted on the mounting frame 306. A transmission gear 311 is movably mounted on... On the connecting frame 310, the transmission gear 311 meshes with the rotating gear 309. The second motor 303 is mounted on the connecting frame 310, and the driving end of the second motor 303 is connected to the transmission gear 311. Four sleeves 301 and four moving rods 302 are provided. The four sleeves 301 are symmetrically arranged in pairs on the base plate 1, and the four moving rods 302 are respectively located inside the four sleeves 301. When the height of the feeding conveyor belt 207 needs to be adjusted to adapt to different feeding machines for easy sorting, the second motor 303 is driven. The second motor 303 drives the transmission gear 311 to rotate on the connecting frame 310. The transmission gear 311 drives the rotating gear 309 to rotate. The rotating gear 309 drives the rotating shaft 307 to rotate on the mounting frame 306. The rotating shaft 307 drives the rotating gear 308 to rotate. The rotating gear 308 drives the moving rack 305 to move on the placement frame 304. The moving rack 305 drives the lifting plate 211 to move. The lifting plate 211 synchronously drives the four moving rods 302 to move in the corresponding sleeves 301. The four-column guide structure effectively limits the unexpected displacement and deflection of the lifting plate 211 during the lifting process, ensuring that the entire height adjustment process is smooth, synchronous, and without jamming, ultimately achieving accurate, stable, and reliable adjustment of the feeding station height.

[0028] Furthermore, the connecting frame 310 is provided with reinforcing ribs, and the moving rod 302 is adapted to the sleeve 301. The reinforcing ribs increase the stability of the connecting frame 310. Through reasonable topology optimization layout, the reinforcing ribs are rigidly connected to the main body of the connecting frame 310 by welding or casting, which significantly improves the bending and torsional stiffness of the connecting frame 310 during the operation of the transmission gear 311, effectively suppresses vibration and deformation, and ensures the operational reliability and durability of the entire lifting transmission system. The adapted moving rod 302 moves stably on the sleeve 301. By selecting appropriate tolerance grades and surface treatment processes, and by pre-setting a lubrication structure on the mating surface, this design ensures that the moving rod 302 has both a low coefficient of friction and high guiding accuracy when it moves linearly in the sleeve 301, effectively avoiding possible jamming, uneven wear or shaking during the lifting process, and providing a stable and reliable vertical guiding function for the lifting plate 211.

[0029] Furthermore, the second motor 303 is fixed to the connecting frame 310 by bolts. The rotating shaft 307 is adapted to the mounting frame 306. The second motor 303, fixed by bolts, is easy to install and remove on the connecting frame 310. This connection method not only provides the motor with sufficient installation rigidity and positioning accuracy to effectively resist the reaction torque and vibration generated during gear transmission, but also facilitates quick alignment adjustment, maintenance or replacement of the motor, significantly improving the maintainability of the power source and the stability and reliability of the system in long-term operation. The adapted rotating shaft 307 rotates stably on the mounting frame 306. This mating structure, through strict tolerance design, appropriate surface hardness treatment and lubrication, ensures that the rotation of the rotating shaft 307 on the mounting frame 306 has low friction and no radial runout, can accurately transmit gear drive torque, effectively suppress vibration and off-center load, and ensure the smoothness and control accuracy of power transmission during lifting and adjustment.

[0030] Furthermore, the movable rack 305 is adapted to the placement frame 304, and the transmission gear 311 is adapted to the rotating gear 309. The adapted movable rack 305 moves stably on the placement frame 304. Through strict tolerance control, appropriate surface hardening treatment and continuous lubrication, this adaptation structure ensures that the movable rack 305 has both a low coefficient of friction and high guiding accuracy during reciprocating motion, effectively suppressing crawling, lateral swaying or jamming that may occur during lifting, providing a smooth, reliable and precise linear motion output for the entire lifting system. The rotating gear 309 moves stably under the action of the transmission gear 311. This gear pair can achieve low noise and high efficiency power transmission during meshing transmission, effectively reducing impact vibration and tooth surface wear, ensuring that the rotating gear 309 rotates at a uniform speed and the transmission is smooth under the drive of the transmission gear 311, and ensuring the accuracy and reliability of lifting height adjustment.

[0031] Working principle: When the height of the feeding conveyor belt 207 needs to be adjusted to adapt to different feeding machines for easy sorting, the second motor 303 is driven. The second motor 303 can drive the transmission gear 311 to rotate on the connecting frame 310. The transmission gear 311 can drive the rotating gear 309 to rotate. The rotating gear 309 can drive the rotating shaft 307 to rotate on the mounting frame 306. The rotating shaft 307 can drive the rotating gear 308 to rotate. The rotating gear 308 can drive the moving rack 305 to move on the placement frame 304. The moving rack 305 can drive the lifting plate 211 to move. The lifting plate 211 synchronously drives the four moving rods 302 to move in the corresponding sleeves 301 for guidance. The four-column guide structure effectively limits the unexpected displacement and deflection of the lifting plate 211 during the lifting process, ensuring that the entire height adjustment process is smooth, synchronous, and without jamming. This ultimately achieves precise, stable, and reliable adjustment of the feeding station height. When sorting of the boards is required, semi-finished boards and waste boards are continuously fed in at intervals via the feeding conveyor belt 207. When the semi-finished boards arrive at the first conveyor belt 206, the system keeps the first conveyor belt 206 in a horizontal conveying state, smoothly transferring them to the second conveyor belt 210 for the qualified product collection process. When waste boards enter the first conveyor belt 206, the first motor 203 starts, driving the crank 204 to rotate. This, through the connecting rod 205, pushes the tilting plate 202 to rotate around the fixed frame 201 by a certain angle, thereby changing the end angle of the first conveyor belt 206 and aligning it with the waste conveyor belt 209. The waste boards slide down into the waste conveyor belt 209 under gravity and the conveyor belt's pull, achieving automatic sorting and realizing continuous, efficient, and reliable sorting operations.
