Description

Technical Field

[0001] This invention relates to the technical field of laminated safety glass recycling and processing equipment, specifically a soaking and turning machine. Background Technology

[0002] Laminated safety glass is widely used in construction, automotive, and other fields. Its recycling requires the separation of polyvinyl butyral (PVB) film, with immersion being the core process. Traditional manual immersion operations require manual placement of broken glass into the immersion tank, repeated bending over to retrieve the material, resulting in high labor intensity and a poor operating environment. Manual immersion relies on natural softening at room temperature, taking over 12 hours and exhibiting extremely low processing efficiency. Manual operation makes it difficult to stably control the water temperature, leading to uneven PVB softening and incomplete separation of glass and film. Furthermore, manual loading and unloading cannot be seamlessly integrated with subsequent processes, hindering automated continuous production and limiting the overall efficiency of laminated glass recycling production lines. Existing immersion equipment lacks an integrated structure for automatic tilting and unloading, precise temperature control, and circulating water treatment, failing to meet the demands for efficient, automated, and low-cost laminated glass recycling. Therefore, the development of an immersion tilting machine is necessary. Summary of the Invention

[0020] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0021] Please see Figures 1-6 The diagram shown is a structural schematic of an embodiment of the soaking and turning machine of the present invention. Please refer to [link / reference]. Figures 1-6 This paper provides a detailed introduction to a soaking and turning machine.

[0022] An immersion and turning machine includes a frame 100, an automatic feeding belt conveyor 101, a hopper 102, an immersion tank 103, a heating rod 104, a water temperature sensor 105, a turning drive motor 106, a position detection photoelectric switch 107, a wastewater tank 108, a water storage tank 109, a circulating water pump 110, a discharge belt conveyor 111, and a PLC controller 112. The frame 100 is made of thick-walled rectangular steel, which is welded and bolted together to form a frame support structure. The top and middle are equipped with reinforcing beams and installation platforms, and the bottom is equipped with adjustable leveling support feet. It can provide a stable and reliable installation benchmark for all parts of the machine. The overall structure has sufficient rigidity, uniform stress, and is not easily deformed during long-term operation. It can stably withstand the load when the hopper 102 is full of glass material and the dynamic load during the turning process, meeting the strength requirements of continuous industrial production. The automatic feeding belt conveyor 101 is fixedly installed at the feed end of the frame 100 in an inclined upward conveying posture. Its feed end is relatively low and is used to directly receive the laminated glass fragments discharged from the front crushing equipment. The discharge end is higher than the opening of the hopper 102, and a guide slide is provided below the discharge end. The center of the discharge port is aligned vertically with the center of the opening of the hopper 102, which can continuously, stably and evenly feed the glass fragments into the hopper 102, effectively avoiding splashing, spillage and accumulation of materials during the conveying and dropping process, and ensuring that the feeding process is smooth and controllable. The soaking tank 103 is made of 304 stainless steel plate through bending, welding, grinding and sealing. It is a rectangular tank structure with an open top. It is sealed and fixed to the main mounting platform in the middle of the frame 100 by brackets and fasteners, forming the core soaking working chamber of the equipment. Multiple heating rods 104 are installed on the inner side wall and bottom of the soaking tank 103. Each heating rod 104 is evenly distributed along the length of the tank to ensure that the water in the tank has a sufficient heating area and uniform temperature distribution, without local overheating or low temperature areas. The water temperature sensor 105 adopts a fully sealed waterproof probe structure. It is fixedly installed in the preset mounting hole on the side wall of the soaking tank 103 through a sealed joint. The detection end is completely inserted into the water body and does not leak out of the tank. It can collect the water temperature signal in the tank in real time and transmit it to the outside. The hopper 102 is made of stainless steel perforated mesh plate welded together. It has a bucket-shaped structure with an open top and an arc or sloping bottom. It is uniformly machined with water filter holes all around, and the diameter of the water filter holes is strictly smaller than the minimum particle size of the broken glass to be processed. This ensures that hot water can freely enter the hopper 102 and fully contact the glass during the soaking process, while completely preventing glass fragments from leaking out and falling from the holes during soaking and turning. A rotating shaft is horizontally fixedly connected to the center of the outer wall on both sides of the hopper 102. The rotating shaft is rotatably mounted on the corresponding support seat of the frame 100 through a bearing. The extended end of the rotating shaft is directly and rigidly connected to the output shaft of the turning drive motor 106. The turning drive motor 106 provides rotational power, which drives the hopper 102 to make a fixed angle rotational movement between the soaking station and the discharge station. The flip drive motor 106 is fixedly mounted on the outer wall of the frame 100 via a motor mount. Its output shaft is coaxially connected to the rotating shaft of the hopper 102, ensuring smooth start-up and accurate positioning. The position detection photoelectric switch 107 is divided into two sets: a reset detection switch and a discharge detection switch, which correspond to the soaking reset position and the flip discharge position of the hopper 102, respectively. It is fixed on the frame 100 via a bracket and aligned with the detection baffle at the rotating shaft. It can detect the rotation angle and position of the hopper 102 in real time and send a position signal in time when it reaches the preset position, so as to achieve precise positioning, stopping and switching of actions. Wastewater tank 108 and water storage tank 109 are fixedly installed side by side in the empty space under the frame 100, with a compact structure and no additional space occupation. The wastewater tank 108 is vertically equipped with a partition, which divides the wastewater tank 108 into two independent chambers: a sedimentation zone and a supernatant purification zone. The bottom of the soaking tank 103 has a drain outlet, which is connected to the sedimentation zone of the wastewater tank 108 through a pipeline and a manual drain valve. After the sewage and glass shards enter the sedimentation zone, the glass shards settle to the bottom of the zone under the action of gravity. The supernatant water overflows from the top of the partition into the purification zone, and then flows into the water storage tank 109 for temporary storage through the connecting pipeline. The inlet of the circulating water pump 110 is connected to the bottom of the water storage tank 109, and the outlet is connected to the inside of the soaking tank 103 through a return pipeline, which can transport the purified water in the water storage tank 109 back to the soaking tank 103 to realize the recycling of water resources. The discharge belt conveyor 111 is fixedly installed on the discharge side of the frame 100 in a horizontal conveying posture. The whole machine is located directly below the discharge port after the hopper 102 is flipped. The feed end is equipped with an arc-shaped receiving baffle, which can effectively receive the glass sheets sliding down from the hopper 102 and prevent material splashing or jamming. The discharge belt conveyor 111 can smoothly transport the soaked glass sheets to the subsequent cleaning, sorting and other processes to realize the continuous flow of the production line. The PLC controller 112 is installed inside a waterproof and dustproof electrical control box on one side of the frame 100. As the central control unit of the whole machine, it integrates a temperature acquisition module, a position signal processing module, a timing logic control module, and a drive output module. The PLC controller 112 is electrically connected to the automatic feeding belt conveyor 101, heating rod 104, water temperature sensor 105, tilt drive motor 106, position detection photoelectric switch 107, circulating water pump 110, and discharge belt conveyor 111 through signal lines. It can complete the coordinated control of the entire process of water temperature control, feeding start and stop, soaking timer, tilt positioning, discharge conveying, and water circulation replenishment according to the preset program, so as to realize the fully automatic operation of the equipment. The working process of this equipment is as follows: After the equipment is started, the PLC controller 112 first starts the heating rod 104 to heat the water temperature in the soaking tank 103 to 40 to 60°C. The water temperature sensor 105 monitors in real time and automatically replenishes the temperature when it is lower than the set value. After the set temperature is reached, it maintains a constant temperature. Automatic feeding belt conveyor 101 feeds broken glass pieces into hopper 102. Hopper 102 is in the soaking position and is completely immersed in hot water. It is kept at a constant temperature for about 80 seconds to make the PVB film soften and separate quickly. After soaking, the PLC controller 112 starts the flip drive motor 106, which drives the hopper 102 to rotate towards the discharge side. When the position detection photoelectric switch 107 detects the discharge position, the machine stops. The glass sheet slides down to the discharge belt conveyor 111 under the action of gravity and is transported to the next process by the discharge belt conveyor 111. After the material is discharged, the flip drive motor 106 reverses, the hopper 102 rotates back to the soaking position, the position detection photoelectric switch 107 detects and resets to the correct position and then stops the machine, waiting for the next feeding and entering the next working cycle; When a large amount of glass shards accumulate in the soaking tank 103, the drain valve is opened, and the sewage and glass shards are discharged into the wastewater tank 108. After sedimentation and separation, the purified water enters the water storage tank 109. The circulating water pump 110 replenishes the purified water back to the soaking tank 103. Once the liquid level reaches the target, the machine automatically stops, and the heating rod 104 reheats to the set temperature to maintain continuous operation.

[0023] I. Working Principle This solution primarily uses PLC controller 112 as the central control unit to coordinate the linkage of various components according to preset timing logic, thereby achieving fully automated operation of the entire process of automatic feeding, constant temperature soaking, precise flipping and discharging of laminated glass fragments, and water circulation and purification. The complete operation process is as follows: After the equipment is powered on and started, the PLC controller 112 first sends a start command to the heating rods 104. Multiple heating rods 104, which are evenly arranged along the inner wall of the soaking tank 103, simultaneously heat the water in the tank. The water temperature sensor 105 collects the water temperature signal in the soaking tank 103 in real time and transmits it to the PLC controller 112. When the water temperature reaches the set value of 40-60℃, the PLC controller 112 controls the heating rods 104 to enter the constant temperature heat preservation state. When the water temperature is lower than the set threshold, it automatically triggers supplemental heating to ensure that the soaking temperature is stable.

[0024] Once the constant temperature condition is met, the PLC controller 112 starts the automatic feeding belt conveyor 101. The inclined automatic feeding belt conveyor 101 continuously transports the laminated glass fragments discharged from the front crushing equipment. Its discharge end is precisely aligned with the top opening of the hopper 102, and the glass fragments are smoothly fed into the hollow hopper 102.

[0025] After the material is fed, the PLC controller 112 starts the soaking timer program. The hopper 102 is kept in the soaking position and completely immersed in the hot water in the soaking tank 103. The hot water comes into full contact with the glass fragments through the hollow hole of the hopper 102, so that the PVB film on the glass surface softens and separates quickly. The soaking time is about 80 seconds.

[0026] After the soaking timer ends, the PLC controller 112 starts the tilting drive motor 106, which drives the hopper 102 to rotate towards the discharge side via the rotating shaft. When the hopper 102 rotates to the discharge limit position, the corresponding position detection photoelectric switch 107 detects the detection baffle and sends a signal to the PLC controller 112. The PLC controller 112 immediately controls the tilting drive motor 106 to stop. Under the action of gravity, the glass fragments slide from the hopper 102 to the discharge conveyor belt 111 below, and are transported by the discharge conveyor belt 111 to the subsequent cleaning and sorting process.

[0027] After the material is discharged, the PLC controller 112 controls the flip drive motor 106 to reverse, driving the hopper 102 to rotate back to the soaking position; when the hopper 102 returns to the reset limit position, the position detection photoelectric switch 107 at the corresponding position sends a reset signal, the PLC controller 112 controls the flip drive motor 106 to stop, and the equipment enters the next feeding-soaking-discharging work cycle.

[0028] When the glass shards in the soaking tank 103 accumulate to a certain amount, the drain valve is opened, and the sewage and glass shards are discharged into the sedimentation zone of the wastewater tank 108 through the pipeline. The glass shards settle to the bottom of the sedimentation zone under the action of gravity, and the upper layer of clean water overflows into the clean water zone through the partition and then flows into the water storage tank 109. When the water level in the soaking tank 103 is lower than the set value, the PLC controller 112 starts the circulating water pump 110 to transport the clean water in the water storage tank 109 back to the soaking tank 103 to replenish the water level. After the liquid level reaches the standard, the circulating water pump 110 automatically stops, realizing the recycling of water resources.

[0029] II. Core Innovation Points The core innovation of this solution lies in its integrated, modular immersion and reversing structure for laminated glass. This solves the industry pain points of traditional manual immersion, such as high labor intensity, extremely low processing efficiency, uneven PVB softening effect, inability to connect with upstream and downstream processes for continuous production, and the limited functionality, fragmented systems, and low automation of existing immersion equipment. Furthermore, it integrates for the first time four core systems—automatic feeding and conveying, closed-loop constant-temperature immersion, precise positioning and reversing for discharge, and zoned sedimentation water circulation—onto a single frame 100, achieving fully automated, continuous operation of the laminated glass immersion process and filling the technological gap in dedicated automated immersion equipment for laminated glass recycling.

[0030] From a technical logic chain perspective: First, it addresses the core pain points of traditional processes, namely "excessive manual intervention, discontinuous processes, and uncontrollable process parameters," by integrating all functional components onto the frame 100 to achieve a unified structural implementation. A PLC controller 112 centrally controls the heating rod 104 and water temperature sensor 105 to form a closed-loop water temperature control system. Combined with the fully immersed design of the hollow hopper 102, the feasibility of constant-temperature uniform immersion is verified. Through the linkage of the flip drive motor 106 and the dual-position detection photoelectric switch 107, precise control of the hopper 102's flip angle and reliable execution of the discharge action are achieved. The wastewater tank 108's zoned sedimentation and the circulating water pump 110's water replenishment design form a closed loop for water resource recycling. Finally, it extends to the recycling and processing of laminated glass of different specifications and thicknesses, possessing broad industrial application value.

[0031] III. Technical Effects of Implementing this Solution Implementing this solution can fundamentally solve many technical challenges in the laminated glass recycling and soaking process, resulting in significant improvements in production efficiency, quality, and costs. Specific technical effects are as follows: The integrated design enhances equipment performance: The feeding, soaking, turning, discharging, and water circulation systems are all integrated into the frame 100, resulting in a compact and rational overall layout. This reduces the floor space by over 40% compared to traditional distributed equipment. Installation and commissioning require only simple fixing and piping connections, significantly reducing installation and transportation costs. The frame 100 is constructed from thick-walled rectangular steel, providing ample structural rigidity to stably withstand the static load of a fully loaded glass hopper 102 and the dynamic load during turning. It is resistant to deformation during long-term continuous operation, reducing equipment failure rates by over 60% and extending service life to over 8 years.

[0032] The efficiency and labor improvements brought by fully automated continuous production: Through the integrated design of the automatic feeding conveyor belt 101, the precise tilting discharge mechanism, and the discharge conveyor belt 111, the arduous traditional manual feeding and retrieval operations are completely replaced. A single unit requires only one person for regular inspection to achieve 24-hour continuous operation, reducing labor intensity by over 90%. It also significantly improves the harsh working environment for workers who are constantly exposed to hot water and glass shards. Regarding processing efficiency, traditional manual soaking at room temperature requires over 12 hours to soften PVB film. This solution, through constant temperature soaking at 40-60℃, requires only 80 seconds per batch, and a single unit can process over 15 tons per day, more than 20 times the efficiency of traditional manual processing. This perfectly matches the capacity requirements of large-scale laminated glass recycling production lines.

[0033] Improved recycling quality through closed-loop constant temperature control: Heating rods 104 are evenly arranged along the inner wall of the soaking tank 103. Combined with real-time detection by the water temperature sensor 105 and closed-loop control by the PLC controller 112, the water temperature fluctuation in the tank can be controlled within ±2℃. This ensures that the soaking environment of all glass fragments is consistent, the PVB film softens evenly and thoroughly, and the separation rate between glass and film reaches over 99%. This significantly improves the purity and quality of recycled glass and avoids equipment blockage and product quality problems in subsequent processes caused by incomplete separation.

[0034] The precise flipping and water circulation design enhances operational reliability and economy: Dual-position photoelectric switches 107 correspond to the discharge and reset limit positions of the hopper 102, achieving a positioning accuracy of ±1°. Combined with the filtration design of the hollowed-out hopper 102, this effectively prevents material scattering, splashing, and jamming during the flipping process, ensuring 100% smooth discharge. It also seamlessly integrates with upstream and downstream crushing, washing, and sorting equipment, enabling continuous automated operation of the entire production line. The water circulation system, through the partitioned sedimentation design of the wastewater tank 108, achieves efficient separation of glass slag and water, with a water resource recycling rate exceeding 85%. This significantly reduces production water costs and wastewater discharge, meeting green and environmentally friendly production requirements.

[0035] Centralized control enhances operation and maintenance convenience: The PLC controller 112, acting as the central control unit, enables digital adjustment of all process parameters, including water temperature, soaking time, feeding speed, and tilting speed, allowing for rapid adaptation to the processing needs of laminated glass of varying thicknesses and types. All vulnerable components are modularly designed for easy disassembly and replacement. Routine maintenance requires only periodic cleaning of glass shards from the wastewater tank 108 and checking the operating status of the heating rod 104, reducing maintenance costs by more than 50% compared to traditional equipment.

An electric regulating valve is installed at the steam pipeline inlet, and the electric regulating valve is electrically connected to the PLC controller 112. The water temperature signal collected by the water temperature sensor 105 is transmitted to the PLC controller 112, which then controls the opening of the electric regulating valve to adjust the steam flow, thereby achieving precise control of the water temperature. The above-mentioned modified solution is suitable for large-scale industrial recycling plants with centralized steam supply systems.

The above-mentioned modified scheme is suitable for processing large-diameter, heavy glass fragments, facilitating rapid cleaning of mesh plate blockages, and improving the braking reliability and load-bearing capacity of the flipping mechanism. It achieves the precise flipping and discharging effect of the present invention and falls within the protection scope of the present invention.

[0038] Application Example 3 of this Solution Another embodiment of the present invention has the same basic structure as the basic embodiment, except that: multiple sets of parallel inclined plate sedimentation components are added to the sedimentation zone of the wastewater tank 108, with the inclined plates arranged at a 60° angle to the horizontal plane; a detachable polypropylene filter element with a filtration accuracy of 5μm is installed at the outlet of the water storage tank 109; the circulating water pump 110 is a variable frequency pump, which is electrically connected to the PLC controller 112, and the PLC controller 112 can adjust the operating speed of the pump according to the water level difference in the soaking tank 103.
