Description

Technical Field

[0001] This invention relates to the field of aluminum profile manufacturing equipment, and particularly to a photovoltaic aluminum profile hot shearing and extrusion system. Background Technology

[0002] Due to its advantages of being lightweight, high-strength, corrosion-resistant, easy to process, and highly recyclable, aluminum profiles are widely used in the manufacturing of photovoltaic equipment as the global demand for clean energy continues to grow and the photovoltaic industry develops rapidly.

[0003] The standard process for aluminum profile manufacturing involves first feeding long aluminum bars into a heating furnace for heating, typically within a specific temperature range of 420℃-530℃. After heating, the long aluminum bars are then cut into shorter segments by a hot shearing machine. The hot shearing process offers significant advantages, resulting in aluminum bars with minimal deformation and a very smooth fracture surface. This characteristic prevents air bubbles from forming due to the fracture surface during subsequent extrusion processes, effectively ensuring the surface quality of the profile. Finally, the short aluminum bars enter an extrusion press, where they are extruded through the die into the desired aluminum profile.

[0004] However, due to the extremely small cross-section of photovoltaic aluminum profiles, the extrusion speed during the process is exceptionally high. This rapid extrusion speed leads to a serious problem: the generation of a large amount of heat causes a sharp rise in processing temperature. The dies used in the extruder are subjected to immense thermal stress, resulting in accelerated die wear. It is worth noting that extruders typically need to operate continuously in actual production to meet large-scale production demands. In this situation, if the short aluminum rods sheared by the hot shearing machine are directly fed into the extruder in the existing production process, without an effective cooling system, this undoubtedly further exacerbates the wear and tear on the dies caused by high temperatures, severely impacting die lifespan, increasing production costs, and affecting product quality stability.

[0005] If a buffer platform is installed between the hot shear and extrusion machines, simply placing short aluminum bars on the platform for natural cooling results in low heat dissipation efficiency. Due to space constraints, the distance between the hot shear and extrusion machines is relatively short, leading to a short buffer platform and a limited number of short aluminum bars that can be buffered for a short period. Because of the significant cooling rate, the short aluminum bars must be transported to the extrusion machine before reaching a suitable temperature, making it difficult to match the tight production rhythm of the hot shear and extrusion machines. Using large industrial fans for cooling has several drawbacks: 1. High energy consumption; 2. Inefficient heat exchange, limited airflow area with many dead zones, and inability to effectively cool numerous short aluminum bars; 3. It easily generates dust in the workshop, and the hot air affects the working environment temperature of surrounding workers.

[0006] It is evident that existing technologies still need improvement and enhancement. Summary of the Invention

[0007] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a photovoltaic aluminum profile hot shearing and extrusion system, which aims to at least solve one of the technical problems existing in the prior art.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A photovoltaic aluminum profile hot shearing and extrusion system includes a feeding mechanism, a multi-bar heating furnace, a hot shearing machine, a buffer cooling platform, and an extruder arranged sequentially. The buffer cooling platform includes a base frame, an inclined plate fixed to the base frame, a swing plate hinged to the base frame at one end, a swing drive mechanism for driving the other end of the swing plate to swing and lift, and a release mechanism set on the inclined plate. The swing plate is located upstream of the inclined plate. The swing plate is provided with a hollow corrugated cooling platform. The top of the corrugated cooling platform forms a corrugated surface extending from front to back. Multiple continuously arranged buffer slots are formed on the corrugated surface. The buffer slots are used to receive short aluminum bars cut by the hot shearing machine. Each buffer slot is semi-circular and has the same diameter as the short aluminum bar. Refrigerant flows inside the corrugated cooling platform. The corrugated cooling platform is connected to an absorption chiller, which enables heat exchange of the refrigerant. The absorption chiller is heated by the waste heat of the multi-bar heating furnace.

[0010] As a further improvement to the above technical solution, the swing drive mechanism includes a first cylinder disposed below the swing plate and facing vertically upward, a support disposed on top of the first cylinder, and rollers disposed on both sides of the support.

[0011] As a further improvement to the above technical solution, the frame of the hot shearing machine is provided with a movable flipping seat located at the unloading point. The frame is provided with a tension spring for resetting the movable flipping seat to face upward. The support is driven to tilt the movable flipping seat to the side through a transmission structure. Below the movable flipping seat is a traction structure for driving the movable flipping seat to tilt towards the wave cooling table. The first cylinder drives the traction structure to run through a triggering structure.

[0012] As a further improvement to the above technical solution, the traction structure includes a pull rope, an eccentric wheel, a coil spring, and a vertical plate mounted on the frame. The axle of the eccentric wheel is rotatably connected to the vertical plate. The inner end of the coil spring is fixed on the axle of the eccentric wheel, and the outer end of the coil spring is fixed on the vertical plate. One end of the pull rope is connected to the movable flipping seat, and the other end is connected to the eccentric wheel.

[0013] As a further improvement to the above technical solution, the triggering structure includes a pin shaft that is mounted on the support and extends laterally, and a right-angled triangular block that is rotatably mounted on the pin shaft. One end face of the right-angled triangular block is a bottom plane, and the other end face is a vertical plane. A torsion spring is provided on the pin shaft. The torsion spring is used to pull the vertical plane of the right-angled triangular block so that the right-angled triangular block abuts against the support, while the bottom plane of the right-angled triangular block faces downward. When the first cylinder drives the support to rise, the inclined surface of the right-angled triangular block contacts the eccentric wheel; when the first cylinder drives the support to fall, the bottom plane of the right-angled triangular block contacts the eccentric wheel.

[0014] As a further improvement to the above technical solution, the base frame is provided with a limiting beam, and the swing plate presses against the limiting beam when placed horizontally. The base frame is provided with buffer springs located on both sides of the limiting beam.

[0015] As a further improvement to the above technical solution, the release mechanism includes a second cylinder, a rotatable and laterally extended shaft at the bottom of the inclined plate, and multiple hook plates arranged laterally at intervals on the shaft. The hook plates are fixedly connected to the shaft, and two of the hook plates are connected by a connecting shaft. The cylinder body of the second cylinder is hinged to the bottom of the inclined plate, and the piston rod end of the second cylinder is hinged to the connecting shaft. The inclined plate has slots that are the same number as the slots and correspond one-to-one. The hook plates can extend upward through the slots to intercept the short aluminum rods.

[0016] As a further improvement to the above technical solution, the inclined plate is provided with an infrared temperature sensor for the temperature of the short aluminum rod on the inclined plate.

[0017] As a further improvement to the above technical solution, the wave cooling stage has baffles arranged inside to form a serpentine refrigerant flow channel.

[0018] As a further improvement to the above technical solution, the absorption chiller includes a generator, a condenser, a throttling valve, an evaporator, and an absorber connected in sequence. The generator contains an aqueous lithium bromide solution. The absorber is supplied with a dilute lithium bromide solution by a first circulation pump. The waste heat from the flue gas heated by the multi-bar furnace is used to heat the generator. One end of the corrugated cooling platform is provided with a refrigerant inlet, and the other end is provided with a refrigerant outlet. The refrigerant inlet and outlet are connected to the evaporator through pipes and the refrigerant is driven to circulate by a second circulation pump.

[0019] The beneficial effects of this invention: Compared with natural cooling and industrial fan cooling, the photovoltaic profile hot shearing and extrusion system provided by this invention has the following advantages:

[0020] 1. The cleverly designed corrugated cooling table features multiple buffer grooves on its corrugated surface, increasing the contact area between the short aluminum rod and the cooling table. The refrigerant flows within the corrugated cooling table, rapidly removing heat from the short aluminum rod and significantly improving cooling efficiency. This effectively reduces wear and tear on the extrusion die caused by high temperatures, extending the die's lifespan. Because cooling is achieved through refrigerant circulation, no dust is generated, and there is no adverse impact on the workshop working environment, providing a more comfortable working environment for staff.

[0021] 2. The coordination of the swing plate, the inclined plate, and the release mechanism can flexibly control the dwell time and transfer speed of short aluminum bars on the buffer cooling table, better matching the tight production rhythm of the hot shear and extrusion machine, and improving production efficiency.

[0022] 3. Absorption chillers utilize the waste heat from multi-bar heating furnaces for heating, eliminating the need for large amounts of additional electricity for cooling, thus significantly reducing energy consumption, aligning with the principles of energy conservation and emission reduction, and lowering production costs.

[0023] 4. By effectively reducing the temperature of the short aluminum rods before extrusion, quality problems such as bubbles caused by high temperatures are reduced, ensuring the surface quality and product quality stability of photovoltaic aluminum profiles. Attached Figure Description

Detailed Implementation

[0032] This invention provides a hot shearing and extrusion system for photovoltaic aluminum profiles. To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the scope of protection of the invention.

[0033] Please see Figures 1 to 7 This invention provides a photovoltaic aluminum profile hot shearing and extrusion system, comprising a feeding mechanism 1, a multi-bar heating furnace 2, a hot shearing machine 3, a buffer cooling platform 4, and an extruder arranged sequentially; the buffer cooling platform 4 includes a base frame 41, an inclined plate 42 fixed to the base frame 41, a swing plate 43 hinged at one end to the base frame 41, a swing drive mechanism 5 for driving the other end of the swing plate 43 to swing and lift, and a release mechanism 48 disposed on the inclined plate 42. The swing plate 43 is located upstream of the inclined plate 42, and the swing plate 43 is provided with a middle An empty corrugated cooling table 44 has a corrugated surface extending from front to back at its top. Multiple continuously arranged buffer slots 45 are formed on the corrugated surface. The buffer slots 45 are used to receive short aluminum rods 6 cut by the hot shearing machine 3. Each buffer slot 45 is semi-circular and has the same diameter as the short aluminum rod 6. Refrigerant flows inside the corrugated cooling table 44. The corrugated cooling table 44 is connected to an absorption chiller 7, which enables the refrigerant to exchange heat. The absorption chiller 7 is heated by the waste heat from the multi-rod heating furnace 2.

[0034] Long aluminum bars are fed into a multi-bar heating furnace 2 via a feeding mechanism 1. The furnace heats the long aluminum bars to a specific range of 420℃-530℃ to prepare for subsequent hot shearing and extrusion processes. This temperature range allows the aluminum bars to achieve suitable plasticity, facilitating subsequent processing. The heated long aluminum bars are then sheared by a hot shearing machine 3, which continuously cuts the long aluminum bars into short aluminum bars 6. The hot shearing process, with its unique cutting method, ensures minimal deformation and a smooth fracture surface. This excellent fracture quality provides a solid foundation for subsequent extrusion processes, effectively preventing air bubbles caused by fracture issues during extrusion, thus ensuring the surface quality of the profile. The short aluminum bars 6 cut by the hot shearing machine 3 are tilted sideways by a movable flipper 81 and fall into the buffer slot 45 at the rear of the corrugated cooling table 44. The lower half of the short aluminum rod 6 fits against the arc surface of the buffer tank 45, allowing for thorough heat exchange between the short aluminum rod 6 and the corrugated cooling table 44. Refrigerant flows inside the corrugated cooling table 44 and circulates under the action of the absorption chiller 7, achieving heat exchange and cooling. The absorption chiller 7 utilizes the waste heat generated by the multi-rod heating furnace 2 for heating, achieving efficient energy utilization.

[0035] As the hot shear machine 3 continues to feed material, the swing plate 43 periodically swings and rises under the action of the swing drive mechanism 5. When the swing plate 43 swings and rises, the short aluminum rods 6 in the previous buffer slot 45 will roll along the wave surface to the next buffer slot 45 due to gravity and the tilt angle of the swing plate 43. On the one hand, this rolling mechanism drives the short aluminum rods 6 to move in an orderly manner towards the inclined plate 42, ensuring the dynamic transfer of the short aluminum rods 6 on the wave cooling table 44. On the other hand, it can effectively prevent the last buffer slot 45 (i.e., the buffer slot 45 closest to the hot shear machine 3) from still containing short aluminum rods 6. In other words, the movable flipper 81 at the feeding point of the hot shear machine 3 will flip the short aluminum rods 6 to the last buffer slot 45. If the buffer slot 45 already contains short aluminum rods 6, it is easy to cause stacking interference. The rolling mechanism of the short aluminum rods 6 can ensure that this situation will not occur. When the short aluminum rod 6 cools down to a certain degree, the swing plate 43 swings to move the short aluminum rod 6 onto the inclined plate 42, and the release mechanism 48 on the inclined plate 42 controls the short aluminum rod 6 to move towards the extruder according to the production rhythm.

[0036] After being cooled by the buffer cooling platen 4, the short aluminum rod 6 enters the extrusion press and is extruded into the required photovoltaic aluminum profile through the extrusion die. Because the short aluminum rod 6 has been cooled, the thermal stress on the die during the extrusion process is significantly reduced, which helps to ensure product quality and extend the service life of the die.

[0037] Compared to natural cooling and industrial fan cooling, the photovoltaic profile hot shearing and extrusion system provided by this invention has the following advantages:

[0038] 1. The cleverly designed corrugated cooling table 44, with its corrugated surface forming multiple buffer grooves 45, increases the contact area between the short aluminum rod 6 and the cooling table. The refrigerant flows within the corrugated cooling table 44, quickly removing heat from the short aluminum rod 6, significantly improving cooling efficiency. This effectively reduces wear and tear on the extrusion die caused by high temperatures, extending the die's lifespan. Because cooling is achieved through refrigerant circulation, no dust is generated, and there is no adverse impact on the workshop working environment, providing a more comfortable working environment for staff.

[0039] 2. The cooperation of the swing plate 43, the inclined plate 42, and the release mechanism 48 can flexibly control the dwell time and transfer speed of the short aluminum rod 6 on the buffer cooling table 4, better match the tight production rhythm of the hot shear machine 3 and the extruder, and improve production efficiency.

[0040] 3. The absorption chiller 7 uses the waste heat of the multi-rod heating furnace 2 for heating, eliminating the need for a large amount of additional electricity to cool, which greatly reduces energy consumption, conforms to the concept of energy conservation and emission reduction, and reduces production costs.

[0041] 4. By effectively reducing the temperature of the short aluminum rod 6 before extrusion, quality problems such as bubbles caused by high temperature are reduced, ensuring the surface quality and product quality stability of photovoltaic aluminum profiles.

[0042] For details, please refer to Figure 5 The swing drive mechanism 5 includes a first cylinder 51 positioned below the swing plate 43 and vertically upward, a support 52 positioned on top of the first cylinder 51, and rollers 53 positioned on both sides of the support 52. The first cylinder 51 serves as a power source, providing a stable and precisely adjustable thrust. In the actual production of the photovoltaic aluminum profile hot shearing and extrusion system, the feeding speed of the hot shear machine 3 is relatively stable. The first cylinder 51 can precisely control the swing frequency and amplitude of the swing plate 43 according to the feeding rhythm of the hot shear machine 3 and the cooling requirements of the short aluminum rods 6 on the wave cooling table 44. For example, by adjusting the air pressure inside the cylinder, the swing plate 43 can be slowly or quickly swung and lifted, ensuring that the short aluminum rods 6 can be rolled and moved between the buffer tanks 45 at a predetermined speed. This effectively avoids problems such as poor conveying of the short aluminum rods 6 or interference from stacking materials caused by the unstable swing of the swing plate 43, ensuring the continuity and stability of the entire production process.

[0043] The rollers 53 located on both sides of the support 52 provide rolling support when the swing plate 43 swings. When the swing plate 43 is raised or lowered, the rollers 53 roll in contact with the surface of the base frame 41, which greatly reduces friction compared to direct sliding friction. This not only reduces energy consumption but also effectively buffers the impact force during the swing of the swing plate 43, further improving the stability of the swing plate 43's movement. This makes the rolling transfer of the short aluminum rod 6 on the wave cooling table 44 smoother, which is conducive to ensuring the orderly operation of the short aluminum rod 6 during the buffer cooling stage.

[0044] The frame of the hot shearing machine 3 is equipped with a movable tilting seat 81 located at the unloading point. In fact, if the movable tilting seat 81 is driven by a separate side-tilting drive mechanism, not only will energy consumption increase, but the swing drive mechanism 5 must also cooperate to form the unloading timing logic. That is, the swing drive mechanism 5 must act first and then reset before the side-tilting drive mechanism can trigger the action to unload. This is to avoid the problem of material stacking interference in the buffer slot 45 and the problem of the movable tilting seat 81 tilting to unload while the swing plate 43 is still in an inclined state, causing the short aluminum rod 6 to fall to the ground. Therefore, it is necessary to use the first cylinder 51 as a drive source for the swing plate 43 and the movable tilting seat 81 to work together, reducing the difficulty of control editing, and ensuring that the short aluminum rod 6 on the swing plate 43 moves forward before the hot shearing machine 3 tilts to unload.

[0045] Furthermore, the frame is provided with a tension spring 82 for resetting the movable tilting seat 81 to face upwards, and the support 52 drives the movable tilting seat 81 to tilt to the side through a transmission structure. Below the movable tilting seat 81 is a traction structure 9 for driving the movable tilting seat 81 to tilt towards the wave cooling table 44; the first cylinder 51 drives the traction structure 9 to run through a triggering structure.

[0046] When the system is in the initial or waiting-to-feed state, the tension spring 82 activates, keeping the movable tilting seat 81 in its reset upward position, and the discharge port of the hot shear machine 3 is closed to prevent the aluminum rod from falling accidentally. The swing plate 43 is in the initial position, and the buffer slot 45 of the wave cooling table 44 is ready to receive the short aluminum rod 6 after hot shearing. At this time, the piston rod of the first cylinder 51 retracts, and no drive is applied to the swing plate 43 and the movable tilting seat 81.

[0047] After the hot shearing machine 3 completes one shearing cycle, the short aluminum rod 6 falls into the movable tilting seat 81. The control system issues a command, and the first cylinder 51 starts working. The piston rod extends and pushes the support 52 upward, causing the swing plate 43 to swing and lift around its hinge point with the base frame 41. During this process, the short aluminum rod 6 in the buffer slot 45 of the corrugated cooling table 44 rolls along the corrugated surface from the current buffer slot 45 to the next buffer slot 45 due to the tilt of the swing plate 43 and the action of gravity, completing the forward movement of the short aluminum rod 6 on the corrugated cooling table 44.

[0048] After the piston rod of the first cylinder 51 extends to the set stroke, it begins to retract. During the retraction process, the traction structure 9 is synchronously driven by the trigger mechanism. Since the actual retraction time is relatively short, as the piston rod of the first cylinder 51 completes its retraction, the swing plate 43 returns to its initial horizontal position. At the same time, the traction structure 9 pulls the movable tilting seat 81 to tilt sideways around its fulcrum on the frame toward the wave cooling table 44. The short aluminum rod 6 on the movable tilting seat 81 tilts sideways and falls into the buffer slot 45 of the wave cooling table 44 closest to the hot shear machine 3.

[0049] After the short aluminum bar 6 is unloaded, the movable flipper 81, under the tension of the tension spring 82, flips upward and resets around the fulcrum. Simultaneously, the swing plate 43 maintains its initial horizontal position, awaiting the next drive of the first cylinder 51. The swing plate 43 and the movable flipper 81 work together under the unified drive of the first cylinder 51 to complete the unloading of the hot shear machine 3 and the orderly transfer of the short aluminum bar 6 onto the corrugated cooling table 44.

[0050] Compared to the previous method, which required the swing drive mechanism 5 and the tilting drive mechanism to work together to form a complex feeding sequence logic, placing higher demands on the programming and debugging of the control system, the current method uses a single first cylinder 51. This simplifies the control program by requiring only the programming around a single drive source, significantly reducing the difficulty of control editing. Whether during the initial installation and commissioning phase or in subsequent production operations, this reduces the risk of malfunctions due to complex control logic and improves the stability of equipment operation.

[0051] The shared first cylinder 51 not only reduces the need for additional power equipment and its energy consumption, but also ensures that the short aluminum rods 6 on the swing plate 43 before the hot shear machine 3 tilts and discharges are moved forward. Through the unified action of the first cylinder 51, the swing plate 43 first swings, rises, and resets before triggering the movable tilting seat 81 to tilt and discharge, fundamentally avoiding interference from the stacked material in the buffer tank 45 and the problem of the short aluminum rods 6 falling to the ground. This not only ensures smooth production and reduces material waste and equipment damage risks, but also improves safety on the production floor and reduces the possibility of workers being injured by falling materials.

[0052] For details, please refer to Figures 3 to 6 The traction structure 9 includes a pull rope 91, an eccentric wheel 92, a coil spring 93, and a vertical plate 94 mounted on the frame. The axle of the eccentric wheel 92 is rotatably connected to the vertical plate 94. The inner ring end of the coil spring 93 is fixed on the axle of the eccentric wheel 92, and the outer ring end of the coil spring 93 is fixed on the vertical plate 94. One end of the pull rope 91 is connected to the movable flipping seat 81, and the other end is connected to the eccentric wheel 92.

[0053] When the piston rod of the first cylinder 51 retracts, the triggering mechanism activates the traction mechanism 9, causing the eccentric wheel 92 to rotate. The eccentric wheel 92 rotates in a circular motion around its axle. As the eccentric wheel 92 rotates, the pull rope 91 connected to it is gradually wound and tightened. Since the other end of the pull rope 91 is connected to the movable tilting seat 81, the tightening of the pull rope 91 generates tension, causing the movable tilting seat 81 to tilt sideways around its fulcrum on the frame toward the wave cooling table 44, allowing the short aluminum rod 6 to be smoothly fed into the buffer slot 45 of the wave cooling table 44.

[0054] After the movable tilting seat 81 completes its side-tilting unloading, the piston rod of the first cylinder 51 retracts, at which point the side-tilting driving force of the movable tilting seat 81 disappears. During the side-tilting process of the movable tilting seat 81, the coil spring 93 stores elastic potential energy due to the rotation of the eccentric wheel 92. When the side-tilting action is complete, the coil spring 93 releases its elastic potential energy, driving the eccentric wheel 92 to rotate in the opposite direction and reset. As the eccentric wheel 92 rotates in the opposite direction, the pull rope 91 is gradually released and retracted. Under the combined force of the elastic potential energy released by the pull spring 82 and the coil spring 93, the movable tilting seat 81 flips upward around the fulcrum and resets, returning to its initial waiting-for-unloading state, completing one full work cycle.

[0055] The traction structure 9 can closely coordinate with the action of the first cylinder 51 to achieve the coordinated work of the swing plate 43 and the movable tilting seat 81. During the retraction of the piston rod of the first cylinder 51, it is precisely triggered to operate, coordinating with the reset action of the swing plate 43, ensuring that the short aluminum rod 6 on the swing plate 43 completes forward movement before the hot shear machine 3 tilts and unloads, thus meeting the strict timing logic requirements of the production process.

[0056] For further details, please refer to [link / reference]. Figures 3 to 5 The triggering structure includes a pin 56 that is mounted on the support 52 and extends laterally, and a right-angled triangular block 54 that is rotatably mounted on the pin 56. One end face of the right-angled triangular block 54 is a bottom plane, and the other end face is a vertical plane. A torsion spring 55 is provided on the pin 56. The torsion spring 55 is used to pull the vertical plane of the right-angled triangular block 54 so that the right-angled triangular block 54 abuts against the support 52, with the bottom plane of the right-angled triangular block 54 facing down. When the first cylinder 51 drives the support 52 to rise, the inclined surface of the right-angled triangular block 54 contacts the eccentric wheel 92; when the first cylinder 51 drives the support 52 to fall, the bottom plane of the right-angled triangular block 54 contacts the eccentric wheel 92.

[0057] When the first cylinder 51 drives the support 52 to rise, the inclined surface of the right-angled triangular block 54 contacts the eccentric wheel 92. The component force of the eccentric wheel 92 on the right-angled triangular block 54 causes the right-angled triangular block 54 to rotate around the pin 56. During this process, the eccentric wheel 92 remains stationary under the action of the coil spring 93, which effectively reduces unnecessary impact on the eccentric wheel 92 during the rising phase and avoids premature activation of the traction structure 9. Only when the first cylinder 51 drives the support 52 to fall, and the bottom plane of the right-angled triangular block 54 presses down on the eccentric wheel 92, is the rotation of the eccentric wheel 92 precisely triggered, thereby driving the pull rope 91 to pull the movable tilting seat 81. This precise start-up control method ensures that the traction structure 9 starts working at the appropriate time, improves the accuracy and stability of equipment operation, and reduces equipment failures and production stoppages caused by malfunctions.

[0058] This triggering structure can adapt well to the movement of the first cylinder 51 in different directions, playing a stabilizing role in different working stages of the equipment. During the upward phase, the rotation of the right-angled triangular block 54 cleverly avoids direct drive to the eccentric wheel 92, and the coil spring 93 maintains the stability of the eccentric wheel 92; during the downward phase, it precisely achieves downward drive of the eccentric wheel 92. This allows the entire hot shear extrusion system to reliably control the side-tilting and unloading action of the movable tilting seat 81 during frequent cylinder reciprocating motions, adapting to various complex production conditions. Whether it's high-speed continuous production or intermittent start-stop operations, it ensures the consistency and reliability of equipment operation, enhancing the equipment's versatility and meeting different production needs.

[0059] For further details, please refer to [link / reference]. Figure 3 and Figure 4 The base frame 41 is equipped with a limiting beam 46. When the swing plate 43 is placed horizontally, it presses against the limiting beam 46. The base frame 41 is equipped with buffer springs 47 located on both sides of the limiting beam 46. The setting of the limiting beam 46 provides a clear horizontal positioning reference for the swing plate 43. When the swing plate 43 swings back to the horizontal state, it will accurately press against the limiting beam 46, ensuring the consistency and accuracy of the position of the swing plate 43 after each reset. This is crucial for the stable operation of the entire photovoltaic aluminum profile hot shearing and extrusion system, because the accuracy of the swing plate 43's position directly affects the buffering and transfer effect of the short aluminum rod 6 on the wave cooling table 44. For example, if the swing plate 43 is not inaccurate, it may cause the short aluminum rod 6 to roll poorly in the buffer groove 45, or even cause jamming or falling. The limiting beam 46 effectively avoids such situations.

[0060] For details, please refer to Figure 7The release mechanism 48 includes a second cylinder 481, a rotating shaft 482 rotatably and laterally extended at the bottom of the inclined plate 42, and multiple hook plates 483 arranged laterally at intervals on the rotating shaft 482. The hook plates 483 are fixedly connected to the rotating shaft 482, and two of the hook plates 483 are connected by a connecting shaft 484. The cylinder body of the second cylinder 481 is hinged to the bottom of the inclined plate 42, and the piston rod end of the second cylinder 481 is hinged to the connecting shaft 484. The inclined plate 42 has slots 421 in the same number and corresponding to the slots 421. The hook plates 483 can extend upward through the slots 421 to intercept the short aluminum rods 6. The movement of the second cylinder 481 can be precisely controlled. The extension and retraction of the piston rod drives the connecting shaft 484, thereby causing the rotating shaft 482 to rotate, realizing the lifting and lowering of the hook plates 483, and realizing the release of a single short aluminum rod 6. Operators can flexibly adjust the action of the second cylinder 481 based on factors such as the working rhythm of the extruder and the cooling status of the short aluminum rod 6, thereby precisely controlling the release timing of the short aluminum rod 6 on the inclined plate 42. For example, when the extruder needs to be fed, the hook plate 483 is lowered in time to allow the short aluminum rod 6 to enter the extruder smoothly; when the extruder is in a short pause or needs adjustment, the hook plate 483 is raised to intercept the short aluminum rod 6, preventing the short aluminum rod 6 from accumulating excessively or entering the extruder prematurely, thus ensuring the orderly progress of the production process.

[0061] The inclined plate 42 is equipped with an infrared temperature sensor to monitor the temperature of the short aluminum rod 6 on it. The extrusion molding of photovoltaic aluminum profiles places strict requirements on the temperature of the short aluminum rod 6. Real-time monitoring of the temperature of the short aluminum rod 6 on the inclined plate 42 by the infrared temperature sensor ensures that the short aluminum rod 6 entering the extruder is within a suitable temperature range. If the temperature is too high, problems such as bubbles and surface roughness may occur during extrusion; if the temperature is too low, the plasticity of the aluminum rod deteriorates, making it difficult to extrude into the required shape, and may even damage the mold. The sensor can provide timely temperature feedback, allowing operators to take appropriate measures, such as adjusting the cooling time or speed of the buffer cooling platform 4, thereby ensuring the stable quality of the extruded aluminum profile.

[0062] Preferably, the corrugated cooling table 44 has baffles arranged inside to form a serpentine refrigerant flow channel. The serpentine refrigerant flow channel, through the rational arrangement of the baffles, significantly extends the flow path of the refrigerant inside the corrugated cooling table 44. Compared to traditional straight-channel flow channels, the refrigerant stays in the cooling table for a longer time, having more opportunities to exchange heat with the short aluminum rods 6. This allows the refrigerant to fully absorb the heat from the short aluminum rods 6, thereby improving the cooling effect. For example, under the same refrigerant flow rate and temperature conditions, the serpentine flow channel allows the refrigerant to carry away more heat, enabling the short aluminum rods 6 to reach the appropriate extrusion temperature more quickly.

[0063] Specifically, the absorption chiller 7 includes a generator, a condenser, a throttling valve, an evaporator, and an absorber connected in sequence. The generator contains an aqueous lithium bromide solution. The absorber is supplied with a dilute lithium bromide solution via a first circulation pump. The waste heat from the flue gas heated by the multi-bar furnace 2 heats the generator. One end of the corrugated cooling platform 44 is provided with a refrigerant inlet, and the other end is provided with a refrigerant outlet. The refrigerant inlet and outlet are connected to the evaporator via pipes and are driven to circulate by a second circulation pump.

[0064] The working principle of the absorption chiller 7 is as follows: The waste heat from the flue gas supplied by the multi-rod heater 2 heats the generator, which contains a lithium bromide aqueous solution. Under the heating of the waste heat, the water in the lithium bromide aqueous solution evaporates, forming high-temperature, high-pressure water vapor, while the solution is concentrated into a concentrated lithium bromide solution remaining in the generator. The high-temperature, high-pressure water vapor from the generator enters the condenser, where it releases heat to the outside, is cooled, and condenses into liquid water. During this process, heat is dissipated to the surrounding environment through the condenser. The liquid water passes through a throttling valve, which reduces pressure and temperature, becoming low-temperature, low-pressure liquid water. This low-temperature, low-pressure liquid water enters the evaporator, where refrigerant from the refrigerant outlet of the wave cooling platform 44 flows into the evaporator through pipes. The liquid water absorbs heat from the refrigerant in the evaporator and evaporates, thereby lowering the temperature of the refrigerant. The cooled refrigerant is pumped back to the refrigerant inlet of the corrugated cooling platform 44 via the second circulation pump, further cooling the short aluminum rods 6 on the platform. Water vapor generated in the evaporator enters the absorber and is absorbed by the dilute lithium bromide solution within. The concentration of the lithium bromide solution is further reduced after absorbing the water vapor, and then the solution is pumped from the absorber to the generator via the first circulation pump for further heating and concentration, completing one full working cycle.

[0065] The entire refrigeration system is based on the absorption refrigeration principle. Compared to traditional compression refrigeration systems, it does not require a large amount of electrical energy to drive the compressor during operation. Refrigeration is achieved through the absorption and regeneration process of lithium bromide aqueous solution, resulting in higher energy efficiency. While meeting the cooling requirements of the wave cooling platform 44, it significantly reduces energy consumption, aligning with the environmental protection concept of energy conservation and emission reduction. The waste heat from the flue gas supplied by the multi-bar heater 2 is used to heat the generator, achieving effective recovery and utilization of industrial waste heat. In traditional refrigeration systems, a large amount of electrical energy or other energy sources are typically required to generate the heat needed for refrigeration. This absorption chiller 7 fully utilizes the waste heat from the flue gas, which would otherwise be wasted, reducing dependence on external energy sources and lowering energy consumption and production costs.
