Description

Technical Field

[0001] This invention relates to the field of aerogel felt preparation technology, and more specifically to an applicator for aerogel felt preparation. Background Technology

[0002] Sizing is a crucial step in the preparation of aerogel felt. Sizing not only strengthens the bond between the aerogel and fiber materials but also effectively improves waterproofing and other properties. In actual processing, sizing is performed in a sizing machine, where the adhesive is sprayed onto the material layer of the forming mesh through the sizing components. After sizing, adhesive residue inevitably remains in the sizing pipes and nozzle structures. If not cleaned promptly, the solidified adhesive will cause significant inconvenience. Currently, workers disassemble the nozzle structures from the sizing pipes for individual cleaning, which is cumbersome and inefficient, failing to meet current needs. Therefore, designing a sizing device for aerogel felt preparation is essential to address these issues. Summary of the Invention

[0003] To address the aforementioned problems, this invention designs an adhesive application device for the preparation of aerogel felts. This device not only heats the nozzle structure during rinsing via a heated cylinder to prevent the adhesive from solidifying and making it easier to remove, but also performs forward and reverse rinsing for a more thorough cleaning of the nozzle structure, thus enhancing its practicality.

[0034] The present invention will be further described in detail below through specific embodiments.

[0035] like Figure 1 , Figure 2 , Figure 6 and Figure 7The illustrated adhesive application device for preparing aerogel felt includes an adhesive application assembly consisting of two adhesive application pipes 19 and several nozzle structures 20 disposed at the bottom of the adhesive application pipes. A cleaning fluid collection box assembly 11 and a backwashing box assembly 9 are respectively disposed on the left and right sides of the adhesive application assembly. The cleaning fluid collection box assembly 11 and the backwashing box assembly 9 are connected to fixed frames 3 on the left and right sides of the adhesive application assembly via a swing mechanism. The fixed frames 3 are inverted U-shapes, with both ends fixedly connected to the top of the adhesive application frame 1 via mounting bases 4. The adhesive application assembly is disposed between the front and rear side walls of the fixed frames. The adhesive application assembly is connected to the top of the fixed frames 3 via a lifting mechanism 7. The backwashing box assembly includes... The flushing box body 9-2 and the first panel 9-1 installed on the top of the flushing box body are provided. The first panel 9-1 has a first countersunk groove at a position relative to a plurality of nozzle structures 20. The first countersunk groove is connected to the first heating cylinder 9-4 through the first elastic cylinder 9-5. The first heating cylinder has a compression cylinder 9-3 fixed inside. The upper end of the compression cylinder has a conical groove. The center of the conical groove has a guide hole for the end of the nozzle structure to pass through. The flushing box body directly below the guide hole is provided with an insertion connector structure 9-6 connected to the backwash pipe. The insertion connector structure is located at the top of the backwash pipe. The above-mentioned lifting mechanism and swing mechanism are controlled by a controller. During operation, the formed aerogel felt preform is conveyed from right to left by the sizing forming mesh 2. The sizing is applied to the aerogel felt preform using the sizing pipe and the nozzle structure at its bottom. After sizing, the lifting mechanism is activated to raise the sizing assembly. Then, the swing mechanism on the left is activated to move the cleaning liquid collection box assembly directly below the sizing assembly. The lifting mechanism is then activated in reverse so that the lower end of the nozzle structure extends into the cleaning liquid collection box assembly. At this time, water is supplied to the sizing pipe, and the first cleaning of the sizing pipe and nozzle structure is completed by the pressurized water flow. After the first cleaning is completed, the sizing assembly continues to rise. At this time, the backwash box assembly is moved directly below the sizing assembly. The sizing assembly continues to descend so that the lower end of the nozzle structure extends into the backwash box assembly. At this time, the sizing pipe and nozzle structure are cleaned a second time through the backwash pipe and the insertion joint structure. This invention not only heats the nozzle structure during rinsing through the heating cylinder to prevent the adhesive from solidifying and making it easier to remove, but also performs forward and reverse rinsing for a more thorough cleaning of the nozzle structure, thus increasing its practicality. Furthermore, the backwashing box assembly allows for simultaneous backwashing of several nozzle structures at the bottom of the adhesive application pipe, greatly improving cleaning efficiency.

[0036] like Figure 8 and Figure 9The cleaning fluid collection box assembly 11 shown includes a collection box body 11-2 and a second panel 11-1 mounted on the top of the collection box body. Each of the second panel 11-1 has a second countersunk groove positioned relative to a plurality of nozzle structures 20. A second heating cylinder 11-3 is connected to each second countersunk groove via a second elastic cylinder 11-4. The ends of the nozzle structures pass through the second panel along the center of the second heating cylinder and extend into the collection box body 11-2. This invention uses the second heating cylinder to prevent the adhesive from solidifying, thus facilitating cleaning.

[0037] like Figure 2 , Figure 4 and Figure 5 The swing mechanism shown includes a swing drive cylinder 17 and swing rods 10. A swing drive cylinder 17 is installed at the top of each of the left and right fixed frames 3 of the adhesive application assembly. The swing drive cylinders are movably connected to the fixed frames. A swing rod connecting frame 8 is provided at the top of each of the left and right ends of the fixed frame 3. The cleaning fluid collection box assembly 11 and the backwash box assembly 9 are connected to the lower ends of the two swing rods via mounting connectors. The upper ends of the two swing rods 10 are movably connected to the swing rod connecting frame 8. The output shaft end of the swing drive cylinder 17 is movably connected to the two swing rods via a drive connector. A through slot is provided on the fixed frame 3 relative to the positions of the swing rods 10 on both sides. During operation, activating the swing drive cylinder causes the cleaning fluid collection box assembly 11 and the backwash box assembly 9 to swing around the swing rod connecting frame 8 under the drive of the swing rods, thereby adjusting the positions of the cleaning fluid collection box assembly 11 and the backwash box assembly 9. This mechanism has the advantages of simple structure, convenient use, and high efficiency.

[0038] like Figure 2 and Figure 3 The lifting mechanism 7 shown includes a worm 7-2, a worm wheel, a nut structure, a screw 7-3, a mounting housing 7-1, and a lifting drive servo motor 7-4. The nut structure and the worm wheel are integrally connected and rotatably mounted within the mounting housing. Two screws are provided, with their lower ends extending into the fixing frame 3 and connected to the top of the mounting frame 12. The upper ends of the two screws pass through the two mounting housings respectively. The screw passes through the worm wheel and the nut structure from the center. The external threads on the screw surface match the nut structure. The screw is movably connected to the worm wheel. The worm 7-2 is horizontally positioned, extending into the two mounting housings 7-1 and connected to the two worm wheels respectively. The lifting drive servo motor is fixed to the mounting housing and connected to one end of the worm 7-2. During operation, the lifting drive servo motor is started to rotate the worm, and the worm wheel's cooperation causes the nut structure to rotate. During the rotation of the nut structure, the screw lifts and lowers the mounting frame.

[0039] like Figure 4 and Figure 5 The two adhesive application pipes 19 shown are connected to the left and right sides of the mounting frame 12 respectively via a front-to-back translation mechanism. The front-to-back translation mechanism is electrically connected to the controller. The front-to-back translation mechanism includes a fixed-angle rotary motor 16 fixed in the mounting frame, a drive gear 21 mounted on the output shaft of the fixed-angle rotary motor, a trapezoidal guide block 15, a guide frame 13, and a connecting rod 18. A guide frame is fixed on each of the left and right sides of the mounting frame. The guide frame has a guide groove that matches the trapezoidal guide block. The trapezoidal guide block 15 is slidably connected to the guide groove, and a toothed structure 14 integrated with it is provided on the side facing the mounting frame. The drive gear passes through the mounting frame and extends into the guide frame, connecting with the toothed structures 14 on both sides. A second through groove for the connecting rod to extend into is provided at the bottom of the guide frame. The adhesive application pipe is connected to the lower end of the two connecting rods through a clamp structure. The upper end of the two connecting rods extends into the guide frame along the second through groove and is fixedly connected to the trapezoidal guide block. The connecting rod slides back and forth along the second through groove under the drive of the trapezoidal guide block. Due to the limitations of the guide frame, the trapezoidal guide block can only translate (i.e., move back and forth) along the guide groove inside the guide frame. Specifically, the working principle involves controlling the fixed-angle rotary motor 16 to rotate by a certain angle. At this time, the toothed structure 14, under the action of the drive gear 21, will carry the trapezoidal guide block to translate. After the fixed-angle rotary motor 16 reaches its position, it will reset and rotate in the opposite direction. At this time, the trapezoidal guide block will translate in the opposite direction under the cooperation of the teeth, and this back-and-forth translational motion is completed in sequence. This invention, through the setting of the back-and-forth translational mechanism, allows the nozzle structure to perform back-and-forth reciprocating motion during adhesive application, resulting in more thorough and complete adhesive application.

[0040] like Figure 10 , Figure 11 and Figure 13The nozzle structure 20 shown includes a fixed nozzle end 20-1, a movable nozzle end 20-2, a frustum-shaped valve core 20-3, a guide seat 20-8, a guide plate 20-9, a hollow outer rod 20-6, and a first spring 20-10. The fixed nozzle end is connected to the adhesive application pipe via a threaded structure on its outer wall. The top of the fixed nozzle end has an inlet / outlet port, and its upper end contains a flow guide chamber 20-1-1 communicating with the inlet / outlet port. The top of the flow guide chamber 20-1-1 has a conical sealing surface matching the frustum-shaped valve core. The bottom of the fixed nozzle end has a connecting chamber 20-1-2 matching the movable nozzle end 20-2. The upper end of the movable nozzle end extends... The flow guide chamber 20-1-1 is connected to the connecting chamber 20-1-2 through the flow guide hole 20-1-3 opened inside the nozzle fixed end. The outer wall of the hollow outer rod is provided with an annular protrusion. The frustum-shaped valve core is fitted on the hollow outer rod above the annular protrusion. The guide seat is installed at the top of the connecting chamber. The guide plate is connected to the guide seat through the first spring. The lower end of the hollow outer rod extends into the guide seat and is connected to the guide plate. The annular protrusion on the hollow outer rod contacts the frustum-shaped valve core under the action of the first spring. The frustum-shaped valve core cooperates with the conical sealing surface under the action of the first spring to seal the inlet and outlet of the liquid. The principle of forward flushing is the same as that of adhesive application. When adhesive application or forward flushing is required, the pressurized adhesive or pressurized water will push the frustum-shaped valve core downward, so that the inlet and outlet are connected to the guide chamber through the gap between the frustum-shaped valve core and the conical sealing surface, as well as the guide groove and the second guide hole. At this time, the adhesive or water will first enter the guide chamber, and then flow into the connecting chamber through the guide hole and perform adhesive application or flushing through the moving end of the nozzle.

[0041] like Figure 10 , Figure 11 and Figure 14A second spring 20-4 is also provided between the movable end of the nozzle and the connecting chamber. A guide rod 20-11 is also movably connected inside the hollow outer rod. The upper end of the guide rod 20-11 extends out of the hollow outer rod and is connected to the sealing plate 20-5. A guide groove 20-7 is also provided inside the upper end of the hollow outer rod. The guide groove is sealed by the sealing plate. A second guide hole 20-6-1 is provided on the outer wall of the guide groove below the annular protrusion. The guide groove is connected to the guide chamber 20-1-1 through the second guide hole 20-6-1. The lower end of the guide rod extends out of the hollow outer rod and passes through the guide seat and is connected to the inner wall of the movable end of the nozzle through the connecting rod 20-12. During backwashing, the moving end of the nozzle, as it descends, will press the second spring upward through the squeezing cylinder. At this time, the sealing plate will separate from the upper surface of the frustum-shaped valve core under the action of the guide rod, thereby opening the guide groove. The backwashing water will then enter the connecting chamber through the moving end of the nozzle, and then enter the guide chamber through the guide hole. The water entering the guide chamber will then enter the guide groove along the second guide hole, and finally enter the adhesive application pipe along the guide groove to complete the backwashing work.

[0042] like Figure 12 The adhesive application pipeline shown has a switch valve assembly 22 installed at each end. One end of the switch valve assembly is connected to a reversing valve assembly 24 via a distributor 23. The reversing valve assembly 24 is connected to the adhesive storage tank and the rinsing water storage tank via pipelines. The other end of the switch valve assembly is connected to a recovery switch valve assembly 25 via a manifold 26. The recovery switch valve assembly is connected to the recovery tank via a pipeline. During adhesive application, the reversing valve assembly is controlled to connect the adhesive storage tank to the distributor, and the switch valve assembly connected to the distributor is opened to complete the adhesive application. During forward rinsing, the reversing valve assembly is controlled to connect the rinsing water storage tank to the distributor, and the switch valve assembly connected to the distributor is opened to complete the first rinsing. During reverse rinsing, the switch valve assembly connected to the manifold and the recovery switch valve assembly are opened, and the second rinsing is completed using the backwash pipeline.

[0043] like Figure 2 A glue recovery and collection hood 5 is also connected to the glue application frame directly below the glue application assembly. The glue recovery and collection hood is funnel-shaped, and its bottom is connected to a return pipe 6. This design allows for the recovery of excess glue, thus saving resources and reducing costs.
