Description

Technical Field

[0001] This invention relates to the field of crushing equipment technology, specifically to an energy-saving multi-blade matrix grinding device. Background Technology

[0002] After long-term operation, photovoltaic panels need to be recycled and pre-treated. Waste photovoltaic panels have a multi-layer composite structure, with layers bonded by high-strength adhesive layers. The inner side has metal lines and fixing screws, and the outer side has a glass frame. The crushing and grinding pre-treatment requires first separating the layers, removing residual connection structures, and treating the adhesive film.

[0003] Existing equipment mostly adopts a single impact crushing or single-blade cutting mode, lacking targeted pretreatment design: on the one hand, the cutting accuracy is insufficient, there are dead corners in operation, and it is difficult to completely cut off the interlayer adhesive layer and residual wires and screws, resulting in high grinding resistance and poor crushing uniformity in the subsequent process; on the other hand, the cutting process lacks effective cooling and lubrication protection, which can easily cause glass thermal cracking and high-temperature softening and adhesion of the adhesive film, resulting in blade encapsulation and blade slit blockage, poor stability of continuous operation of the equipment, and rapid blade wear. At the same time, there is a lack of material classification and guiding structure, resulting in mixed crushing of different material layers, which affects the purity of subsequent resource recovery. To address this, we propose an energy-saving multi-blade matrix grinding equipment. Summary of the Invention

[0016] Compared with the prior art, the present invention provides an energy-saving multi-blade matrix grinding device, which has the following beneficial effects: 1. Through the cooperation of the laser probe and accessories such as the threaded rod and upper cutting blade, the laser probe accurately positions the interlayer bonding area. The seventh motor drives the threaded rod for transmission, and the guide rod provides limit guidance, ensuring that the upper cutting blade is precisely aligned with the bonding layer. The sixth motor drives the upper cutting blade to rotate at high speed, and the upper cylinder provides feed power, achieving the effect of precise cutting and separation of the interlayer adhesive layers, avoiding the incomplete separation caused by the offset of traditional cutting. Through the cooperation of the fourth gear and accessories such as the lower cutting blade, the fifth motor drives the fourth gear to mesh with the second gear. The second gear pushes the pin through the arc-shaped guide groove, and the pin drives the T-shaped push rod along the sliding groove rod. The telescopic design allows the lower cutting blade to adapt to different interlayer spaces, achieving the effect of cutting residual lines and screws without dead angles. This solves the problems of limited cutting range and residual connection structures affecting subsequent grinding in existing technologies. Through the cooperation of accessories such as pins, T-shaped push rods, and lower cutting blades, the fifth motor drives the fourth gear to mesh with the second gear. The second gear pushes the pin through the arc-shaped guide groove. The pin drives the T-shaped push rod to extend and retract along the sliding groove rod, allowing the lower cutting blade to adapt to different interlayer spaces. This achieves the effect of cutting residual lines and screws without dead angles, solving the problems of limited cutting range and residual connection structures affecting subsequent grinding in existing technologies.

[0017] 2. Through the cooperation between the annular toothed plate, the lower cutting blade, and the second motor, the annular toothed plate drives multiple sets of lower cutting blades to perform circular motion, forming a multi-blade matrix for surrounding cutting. The second motor adjusts the cutting angle in real time, ensuring that the lower cutting blades always fit against the photovoltaic panel frame, forming cross-stress grooves on the panel surface. Utilizing the stress concentration effect, this achieves the effect of rapid panel breakage during subsequent grinding, significantly reducing grinding pressure, and improving crushing efficiency. Through the cooperation between the grinding disc, the lower cutting blade, the liquid storage tank, the hose, and the solenoid valve spray head, the grinding disc self-grinds the cutting edge of the lower cutting blade in real time. The photovoltaic cutting fluid is cooled, lubricated, and chip removed in one go through the hose and the solenoid valve spray head, thus extending the blade's service life, reducing the frequency of downtime for replacement, and indirectly improving the continuous operation efficiency of the equipment.

[0018] 3. Through the cooperation of the storage tank, hose, and solenoid valve spray head, a closed-loop cooling and lubrication system is formed. The cutting fluid is precisely sprayed onto the cutting area through the hose and solenoid valve spray head, achieving rapid heat removal and preventing photovoltaic glass from cracking due to thermal stress. At the same time, a lubricating film is formed on the blade surface, preventing the film from softening and sticking, efficiently dispersing debris, preventing kerf blockage and blade entanglement, and ensuring continuous and stable cutting action. Through the cooperation of the lower cylinder and the rotating plate, the lower cylinder drives the rotating plate to flexibly adjust the angle through the universal coupling, and the rotating plate is precisely aligned with the layer. The opening separates the outer photovoltaic panel from the middle functional layer into different areas of the material distribution box, achieving preliminary classification and collection, and avoiding the mixing of different materials from affecting the purity of subsequent grinding products. This solves the problem of low recycling rate caused by material mixing in existing technologies. Through the cooperation between the clamping plate, universal wheels, first gear and annular toothed plate, the clamping plate holds the annular toothed plate and cooperates with the universal wheels for limiting, and the first gear meshes with the annular toothed plate for transmission. This achieves the effects of ensuring the stability of multi-blade matrix circumferential cutting, avoiding cutting deviation that causes equipment wear, improving overall operational reliability and reducing maintenance costs.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0022] The following electrical components are all electrically connected via an external PLC controller.

[0023] Please see Figures 1-13 An energy-saving multi-blade matrix grinding device includes an operating table 1, a buffer chamber 2 fixedly connected to the upper end of the operating table 1, a feed inlet at the upper end of the buffer chamber 2, at least two mutually symmetrical first motors 3 installed on the outer side of the buffer chamber 2, a cutting mechanism 4 for processing photovoltaic panels installed on the inner side of the buffer chamber 2, the cutting mechanism 4 including a moving component 41 for circumferential positioning, a cutting component 42 for cutting stress marks on the photovoltaic panels, a panel separating mechanism 5 for layering photovoltaic panels installed near the upper part of the inner side of the buffer chamber 2, two electric rollers at the upper end of the buffer chamber 2, and a guide mechanism 6 for recycling photovoltaic panels at the lower end of the operating table 1.

[0024] In this embodiment, the moving component 41 includes at least two symmetrical first gears 411. The first gears 411 are fixedly connected to the output shaft of a first motor 3 corresponding to the lower end. Two clamping plates 412 are fixedly connected to the outer side of the first gears 411. An annular toothed plate 413 is provided between the two clamping plates 412. The outer side of the annular toothed plate 413 is meshed with the first gears 411. The annular toothed plate 413 is rotatably connected to the inner side of the buffer chamber 2. Sliding grooves are provided at both the upper and lower ends of the annular toothed plate 413. Universal wheels 414 are provided at the adjacent ends of the two clamping plates 412. The universal wheels 414 are rotatably connected to the inner side of the sliding groove of the annular toothed plate 413.

[0025] Specifically, the first motor 3 provides the power for the circular drive, driving the first gear 411 to rotate via its output shaft, thus enabling the entire annular toothed plate 413 to perform circular motion within the buffer chamber 2. The first gear 411 meshes with the annular toothed plate 413, transmitting the power of the first motor 3 to the annular toothed plate 413, causing it to rotate as a whole. The clamping plate 412 clamps and positions the annular toothed plate 413 and, in conjunction with the universal wheel 414, rolls to limit the radial runout of the annular toothed plate 413, ensuring rotational stability. The annular toothed plate 413 serves as the bearing base for the multi-blade matrix, driving multiple lower cutting blades 4217 to perform circular motion, achieving the circular cutting and stress groove processing of the photovoltaic panel frame. The sliding groove, in conjunction with the universal wheel 414, forms a rolling guide, reducing the rotational friction of the annular toothed plate 413 and lowering energy consumption. The universal wheel 414 rolls within the sliding groove, reducing friction between the annular toothed plate 413 and the clamping plate 412, improving equipment operational stability and energy efficiency.

[0026] In this embodiment, a plurality of fixing frames 421 are arranged around the lower end of the annular toothed plate 413. A support plate 422 is rotatably connected to the inner side of the fixing frame 421 via a rotating shaft. A second motor 423 is installed at the front end of the fixing frame 421. The output shaft of the second motor 423 is fixedly connected to the support plate 422. A liquid storage tank 420 is fixedly connected to the upper end of the support plate 422. Photovoltaic cutting fluid is stored inside the liquid storage tank 420. A third motor 424 is installed at the lower end of the support plate 422.

[0027] Specifically, the mounting bracket 421 is used to install the support plate 422 and the second motor 423, and provides a rotation fulcrum for the support plate 422 to ensure stable angle adjustment. The support plate 422 is used to install the second motor 423, the liquid storage tank 420, the third motor 424, and the guide bracket 428, and can rotate around the mounting bracket 421 to adjust the angle of the lower cutting blade 4217, adapting to the frame position of photovoltaic panels of different sizes. The second motor 423 is an energy-saving motor used to drive the support plate 422 to rotate around the axis, adjusting the cutting angle of the lower cutting blade 4217 to ensure precise fit with the frame for circumferential cutting. The liquid storage tank 420 is used to store photovoltaic cutting fluid, providing a continuous cooling, lubrication, and chip removal medium for the cutting assembly 42. The third motor 424 is used to drive the first pulley 425 to rotate, transmitting power through the synchronous belt 427 to drive the guide bracket 428 to rotate. The first pulley 425 cooperates with the synchronous belt 427 to transmit the power of the third motor 424 to the second pulley 426, realizing the angle adjustment of the guide bracket 428.

[0028] In this embodiment, a second pulley 426 is rotatably connected to the other side of the support plate 422 via a rotating shaft.

The guide bracket 428 mounts the electric actuator 429, mounting block 4210, lower sleeve 4214, and fourth motor 4213, and provides multi-directional motion guidance for the lower cutting blade 4217. The slide groove cooperates with the mounting block 4210 to provide a precise displacement path for the solenoid valve spray head 4211 and the grinding disc 4212.

[0039] Specifically, the upper cylinder 51 drives the mounting frame 52 to feed towards the photovoltaic panel, providing pressing and positioning power for interlayer cutting. The mounting frame 52 carries the laser probe, the sixth motor 53, the cavity rotating plate 54, and the upper cutting blade 57, forming the overall execution mechanism for interlayer cutting. The laser probe is used for visual positioning of the interlayer bonding position of the photovoltaic panel, providing a precise alignment reference for the upper cutting blade 57. The sixth motor 53 is an energy-saving motor used to drive the cavity rotating plate 54 to rotate, thereby driving the upper cutting blade 57 to perform interlayer cutting.

The lower end of the rotating plate 63 is rotatably connected to the inner side of the material distribution box 61 through a rotating shaft.

[0041] Specifically, the sorting box 61 is used to classify and guide different layers of the photovoltaic panel, achieving initial material separation. The lower cylinder 62 is used to drive the rotating plate 63 to rotate and adjust its angle to match the opening position between the photovoltaic panel layers, forming a sorting channel. The universal coupling is used to connect the lower cylinder 62 and the rotating plate 63, allowing the rotating plate 63 to rotate flexibly within the sorting box 61 and maintain a stable connection. The rotating plate 63 is used to separate the internal space of the sorting box 61, guiding the front and rear outer panels and the middle layer of the photovoltaic panel into different areas, avoiding the mixing of different materials from affecting subsequent grinding.

[0042] Working principle: When in use, the photovoltaic panel with the frame removed is put into the feed port above the buffer chamber 2. The photovoltaic panel is then clamped and positioned by the two electric rollers at the top of the buffer chamber 2. The energy-saving drive motors of the electric rollers are started, and the photovoltaic panel is smoothly conveyed downward to the working area of ​​the separating mechanism 5 by rotating in opposite directions. The separating mechanism 5 is started to pre-process and cut the interlayer adhesive layer of the photovoltaic panel to reduce the resistance for subsequent crushing and grinding. First, the laser probe inside the mounting frame 52 is activated to precisely locate the bonding joints between the multi-layer photovoltaic panels. Then, the seventh motor 59 is activated, and its output shaft drives the threaded rod 55 to rotate. Under the limiting and guiding action of the guide rod 58, the threaded rod 55 drives the upper sleeve 56 to move linearly along the guide rod 58 through threaded transmission, thereby driving the upper cutting blade 57 to precisely align with the bonding joints between the photovoltaic panel layers. Next, the sixth motor 53 is activated, and its output shaft drives the upper cutting blade 57 to rotate at high speed through the cavity rotating plate 54 to achieve the cutting action. At the same time, the upper cylinder 51 is activated, and its output shaft pushes the mounting frame 52 and the upper cutting blade 57 towards the photovoltaic panel, completely cutting and separating the bonding layers between the photovoltaic panel layers, achieving the initial separation of the photovoltaic panel layers, and reducing the risk of material adhesion in the subsequent crushing process. After the photovoltaic panels are separated into layers, they are continuously conveyed downwards. First, the layered flow is guided by the guide mechanism 6. Then, the lower cylinder 62 is activated, and its output shaft drives the rotating plate 63 to rotate inside the material distribution box 61 through the universal coupling and adjusts the angle so that the upper end of the rotating plate 63 is precisely aligned with the opening after the photovoltaic panels are separated into layers. The rotating plate 63 divides the material distribution box 61 into multiple independent areas, so that the front and rear outer panels and the middle functional layer of the photovoltaic panels enter the corresponding areas during the falling process, achieving preliminary classification and collection, and avoiding the mixing of different materials from affecting the subsequent grinding efficiency. Then, the cutting assembly 42 is operated. First, the second motor 423 is started, and its output shaft drives the support plate 422 to rotate around the pivot within the fixed frame 421 to adjust the angle, so that the lower cutting blade 4217 approaches and extends into the interlayer space of the photovoltaic panel. This is used to cut the remaining connection lines or fixing screws between the multiple photovoltaic panels, achieving complete separation of the photovoltaic panel layers. Then, the fifth motor 4221 is started, and its output shaft drives the fourth gear 4222 at the front end of the third gear 4220 to rotate. The fourth gear 4222 drives the second gear 4219 to rotate through meshing transmission. The second gear 4219 pushes the pin 4218 along the arc-shaped guide groove on the outside by the curvature change of the arc-shaped guide groove. As the groove slides, the pin 4218 simultaneously drives the T-shaped push rod 4216 to extend radially outward along the sliding groove rod 4215, allowing the lower cutting blade 4217 to extend to the required stroke, adapting to the working space of different widths between photovoltaic panel layers and avoiding cutting dead angles; the fourth motor 4213 is started, and its output shaft drives the lower sleeve 4214 to rotate at high speed inside the guide bracket 428, driving the lower cutting blade 4217 to thoroughly cut the residual lines and screws on the inside of the photovoltaic panel. At the same time, the frosted surfaces at both ends of the lower cutting blade 4217 are used to clean the burrs of the residual adhesive on the inside of the photovoltaic panel, preventing the adhesive from sticking to the grinding particles during subsequent grinding and ensuring uniform crushing; While the lower cutting blade 4217 completes angle adjustment and performs cutting, the electric actuator 429 is simultaneously activated. Its output shaft pushes the mounting block 4210 to slide smoothly along the groove of the guide bracket 428, allowing the mounting block 4210 to precisely align the solenoid valve spray head 4211 and the grinding disc 4212 with the lower cutting blade 4217. The grinding disc 4212 contacts the high-speed rotating lower cutting blade 4217, achieving real-time self-grinding of the cutting edge, maintaining the sharpness of the lower cutting blade 4217, and ensuring the stability of the cutting effect. Simultaneously, through electric... The solenoid valve controls the opening of the spray head 4211, which delivers the photovoltaic cutting fluid in the storage tank 420 to the spray head through the hose. The fluid is then sprayed onto the cutting area and the surface of the lower cutting blade 4217, quickly removing the heat generated during cutting. This prevents the photovoltaic glass from cracking due to thermal stress and the cutting blade from overheating and wearing out. It also prevents the adhesive film from softening and sticking due to high temperature. The cutting fluid forms a lubricating film on the blade surface, reducing cutting resistance and the probability of blade breakage. It also efficiently disperses glass fragments and silicon powder, preventing slit blockage or blade entanglement, and ensuring the continuity and stability of the cutting action. After the remaining connecting structure inside the photovoltaic panel is cut, the layers of the photovoltaic panel within the cutting mechanism 4 area are completely separated. At this time, the lower cutting blade 4217 is moved out of the interlayer space of the photovoltaic panel by angle adjustment and adjusted to a position that fits the frame of the photovoltaic panel. The third motor 424 is started, and its output shaft drives the first pulley 425 to rotate. The first pulley 425 drives the second pulley 426 to rotate synchronously through the synchronous belt 427. The second pulley 426 drives the guide bracket 428 to rotate around the support plate 422 as the axis to adjust the angle. The rotation angle is controlled within 180 degrees. The lower cutting blade 4217 is adjusted to a suitable angle according to the model and specifications of the photovoltaic panel. The first motor 3 is started, and its output shaft drives the first gear 411 to rotate. Multiple first gears 411 mesh in concert to drive the annular toothed plate 413 to rotate smoothly inside the buffer chamber 2. The clamping plate 412 clamps and limits the annular toothed plate 413. To prevent the annular toothed plate 413 from tilting during rotation, the universal wheels 414 roll within the grooves at both ends of the annular toothed plate 413, reducing frictional resistance and energy consumption during rotation. The annular toothed plate 413 drives multiple lower cutting blades 4217 in a circular motion, while the second motor 423 continuously adjusts the angle of the lower cutting blades 4217 to ensure they remain in contact with the photovoltaic panel frame for circumferential cutting. This results in segmented cutting of the continuously downward-moving outer side of the photovoltaic panel, forming multiple sets of intersecting stress cutting grooves on the photovoltaic panel surface. These cutting grooves serve as weak points for subsequent grinding, concentrating the impact force on the photovoltaic panel during the grinding process at the cutting grooves. This achieves rapid crushing and effectively reduces the working pressure of the grinding mechanism, improving overall crushing efficiency and uniformity. Furthermore, the coordinated control of various energy-saving motors further reduces the overall energy consumption of the equipment.
