Description

Technical Field

[0001] This invention relates to the field of aerogel technology, specifically to an aerogel material production and molding apparatus and molding method. Background Technology

[0002] Aerogel is a porous three-dimensional network structure composed of a nanoscale solid framework, possessing low density and excellent thermal insulation properties. However, aerogel itself is relatively brittle, so it is composited with carbon fiber, glass fiber, ceramic fiber, etc., through special processes to produce soft thermal insulation rolls.

[0003] In response, Chinese patent CN118219588A proposes a production and processing molding device and method for thermal insulation aerogel materials, including a worktable. Two second hydraulic cylinders are mounted on the upper surface of the worktable. The output ends of the two second hydraulic cylinders are fixed to the same fixed frame. Two first grooves are formed inside the fixed frame. A support frame is fixed to the upper surface of the fixed frame, and a first hydraulic cylinder is fixed to the upper surface of the support frame. A base plate is fixed to the output end of the first hydraulic cylinder. Several injection tubes are fixed to the lower surface of the fixed frame. Two fixing rods are provided on both sides of the upper surface of the worktable. A rotating roller is rotatably arranged between the fixed rods, and an auxiliary roller is rotatably arranged below the rotating roller. By setting up structures such as fan blades and extrusion plugs, the problem of residual impurities in the aerogel preparation process clogging the pipes, nozzles, or injection needles of the injection device is solved. However, in actual use, since it only drives the fan blades to rotate by the flow of aerogel to solve the blockage of the pipes, the flow rate of aerogel will also decrease during the process of driving the fan blades to rotate. Moreover, the fan blades can only provide a turbulence effect and cannot provide sufficient impact force when the pipes are blocked. As a result, the problem of uneven aerogel delivery and poor quality in the production of aerogel insulation felt still occurs. Summary of the Invention

[0024] A method for producing and molding an aerogel material includes the following steps:

[0025] Step 1: Place the glass fiber mat to be processed on the processing table and transport the area where the aerogel needs to be injected to the bottom of the delivery tube;

[0026] Step 2: Under the action of the supporting pumping mechanism, the aerogel is transported to the storage box through the piston cylinder;

[0027] Step 3: As the amount of aerogel in the storage box gradually increases, the aerogel will enter the hollow tube through the pressurization control component, thereby driving the follow-up translation component to move through the pressurization control component.

[0028] Step 4: The follow-up translation component will also drive the strength adjustment mechanism to move, so as to control the movement of the conveying pipe to the position that matches the feeding hole through the sealing plate. The aerogel in the storage box will be conveyed to the glass fiber mat through the conveying pipe.

[0029] Step 5: The supporting pumping mechanism will also drive the negative pressure suction mechanism to move, and after the aerogel pumping is completed, it will adsorb the aerogel remaining in the storage box.

[0030] Compared with the prior art, the beneficial effects of the present invention are: the present application can maintain a large pressure during aerogel transportation to prevent the transportation pipeline from being blocked by impurities or other residual components during the transportation process. When the supporting pump mechanism is working, the aerogel in the piston cylinder can be transported to the storage box. As the amount of aerogel increases, the aerogel will gradually enter the hollow tube and drive the follow-up translation component and the strength control mechanism to move through the pressure control component, so as to drive the transportation pipe to the position that matches the feeding hole through the sealing plate. At this time, the aerogel will be transported to the surface of the glass fiber mat through the transportation pipe, and the entire pipeline will always remain unobstructed.

[0031] After the aerogel is delivered, the supporting pump mechanism will also drive the negative pressure suction mechanism to move, so that the aerogel remaining in the storage box enters the negative pressure suction mechanism, thereby preventing the aerogel from dripping.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0047] Please see Figures 1-12 In this embodiment of the invention, an aerogel material production and molding apparatus includes: a processing table 1, a lifting plate 2, a piston cylinder 7, a support pumping mechanism, a storage box 14, a feeding hole 15, a hollow pipe 16, a pressure regulating component, a follow-up translation component, a sealing plate 24, a conveying pipe 25, a strength regulating mechanism, and a negative pressure suction mechanism. To prevent impurities or other residual components from clogging the conveying pipe during aerogel transport, a relatively high pressure needs to be maintained during aerogel transport to ensure unobstructed flow. When the support pumping mechanism is working, it can pump the gas from the piston cylinder 7... The aerogel is delivered to the storage box 14. As the amount of aerogel increases, the aerogel will gradually enter the hollow tube 16. The pressure control component drives the follow-up translation component and the strength control mechanism to move, so that the sealing plate 24 drives the delivery pipe 25 to the position that matches the feeding hole 15. At this time, the aerogel will be delivered to the surface of the glass fiber mat through the delivery pipe 25. After the aerogel delivery is completed, the support pumping mechanism will also drive the negative pressure suction mechanism to move, so that the aerogel remaining in the storage box 14 enters the negative pressure suction mechanism, thereby preventing the aerogel from dripping.

[0048] Specifically, the following are included:

[0049] A processing table 1, and a lifting plate 2 installed on the processing table 1, wherein a piston cylinder 7 is provided on the top of the processing table 1;

[0050] Also includes:

[0051] Please see Figures 1-6 , Figure 8 , Figure 9A supporting pumping mechanism is mounted on the piston cylinder 7. A storage box 14 is connected to the supporting pumping mechanism. The bottom of the storage box 14 has multiple feeding holes 15 evenly distributed. The supporting pumping mechanism can transport the material in the piston cylinder 7 to the storage box 14. The supporting pumping mechanism includes a rotating rod 8 rotatably mounted in the piston cylinder 7 and rotatably connected to the storage box 14. A first feeding groove 12 is provided on the outer circumference of the rotating rod 8. A guide column 9 is symmetrically arranged in the piston cylinder 7 and connected to the storage box 14. A pushing assembly connected to the rotating rod 8 is provided in the piston cylinder 7. The pushing assembly includes a first annular groove 801 opened on the outer circumference of the rotating rod 8. A piston disc 10 is slidably mounted on the rotating rod 8 and slidably connected to the guide column 9. The piston disc 10 is slidably and sealed to the piston cylinder 7. A first limiting block 11 is provided on the inner wall of the piston disc 10 and slidably connected to the first annular groove 801.

[0052] In detail, the lifting plate 2 is provided with symmetrically arranged fixed sleeves 3. A movable rod 4 is slidably installed inside the fixed sleeve 3. A lifting plate 5 is provided at the end of the movable rod 4 away from the fixed sleeve 3. The lifting plate 2 is also provided with a cylinder 6. The output end of the cylinder 6 is connected to the lifting plate 5. The lifting plate 5 is used to support the glass fiber mat for preparing aerogel materials. The rotating rod 8 is partially hollow and connected to the first feed trough 12. A conduit is connected to the piston cylinder 7. The conduit is used to transport the prepared aerogel. The piston cylinder 7 is also provided with a one-way valve that is connected to the conduit and the first feed trough 12 respectively. Under the action of the one-way valve, it is ensured that the piston cylinder 7 can only be fed through the conduit and discharged through the first feed trough 12. The first annular groove 801 is composed of two spiral grooves, and the spiral groove has half a turn.

[0053] When it is necessary to prepare aerogel materials, the glass fiber mat can be placed on the lifting plate 5, and the lifting plate 5 is driven to move under the action of the cylinder 6, which in turn drives the movable rod 4 to move away from the fixed sleeve 3. When the lifting plate 5 moves to the position that matches the conveying pipe 25, the cylinder 6 stops moving. In the initial state, the first limiting block 11 is located at the end of the stroke of the first annular groove 801 away from the lifting plate 2, so that the piston disc 10 is also located at the end of the stroke away from the lifting plate 2. The piston cylinder 7 is filled with aerogel. When it is necessary to pump the aerogel, the rotating rod 8 can be driven to rotate by an external motor, thereby driving the first limiting block 11 to move. Under the action of the first limiting block 11 and the first annular groove 801, the piston disc 10 moves along the length direction of the guide column 9. The guide column 9 has a guiding function to ensure that the piston disc 10 does not rotate with the rotating rod 8 when it moves. Under the action of the piston disc 10, the aerogel in the piston cylinder 7 is conveyed to the hollow part of the rotating rod 8 through the first feed groove 12, and then conveyed to the storage box 14 through the rotating rod 8.

[0054] Preferably, during the aerogel preparation process, there may be some residues in the raw materials or impurities introduced during the preparation process. This may cause blockage of the hollow part of the rotating rod 8, resulting in the aerogel not being transported normally. This leads to uneven aerogel injection in some glass fiber mats, which in turn affects the production efficiency and quality of aerogel insulation mats. Therefore, it is necessary to ensure that a certain pumping pressure is maintained during the aerogel transport process. As the aerogel is gradually added into the storage box 14, the storage box 14 will gradually fill up. When the storage box 14 is full, the pressure in the hollow part of the rotating rod 8 will also increase. Under the action of pressure, the pressure control component will move, and the sealing plate 24 will move through the follow-up translation component. When the pressure reaches the required level, the conveying pipe 25 will move to the position where it connects with the feeding hole 15. At this time, the aerogel in the storage box 14 can be transported to the glass fiber mat through the feeding hole 15 and the conveying pipe 25.

[0055] Please see Figures 1-4 , Figure 6 , Figure 8 , Figure 9A hollow tube 16 is mounted on the supporting pumping mechanism. A pressure regulating component connected to the supporting pumping mechanism is mounted on the hollow tube 16. The pressure regulating component includes a fixing ring 1601 mounted on the inner wall of the hollow tube 16. A first sealing disc 17 that abuts against the fixing ring 1601 is slidably mounted inside the hollow tube 16. A sliding sleeve 18 sleeved on the rotating rod 8 is mounted on the first sealing disc 17. The component also includes a movable plate 19 mounted on the end of the sliding sleeve 18 and slidably connected to the guide post 9. A first spring 20 that abuts against the movable plate 19 is mounted on the guide post 9. A second feed groove 13 that communicates with the hollow tube 16 is opened on the rotating rod 8.

[0056] It should be noted that, initially, the first spring 20 is in a compressed state, causing the movable plate 19 to be at the end of its stroke away from the lifting plate 2. Under the action of the movable plate 19, the sliding sleeve 18 controls the first sealing plate 17 to be in contact with the fixed ring 1601. Under the action of the movable plate 19, the follow-up translation component and the sealing plate 24 control the conveying pipe 25 to be separated from the feeding hole 15. Under the action of the sealing plate 24, the feeding hole 15 is blocked. When it is necessary to pump the aerogel, under the action of the piston plate 10, the aerogel in the piston cylinder 7 enters the storage box 14 through the first feed groove 12 and the rotating rod 8. As the amount of aerogel conveyed increases, the storage box 14 and the rotating rod... As the pressure in the hollow part of the rotating rod 8 gradually increases, the aerogel inside the hollow part will be transported to the hollow tube 16 through the second feed trough 13. The pressure inside the hollow tube 16 will also increase. Under the action of the pressure, the first sealing plate 17 will be pushed to move towards the storage box 14. The first sealing plate 17 will also drive the movable plate 19 to move through the sliding sleeve 18 and compress the first spring 20. The movable plate 19 will also drive the follow-up translation component to move. When the pressure inside the hollow tube 16 reaches the required level, the follow-up translation component will drive the conveying pipe 25 to move to the position that matches the feeding hole 15 through the sealing plate 24. The aerogel inside the storage box 14 will be transported to the surface of the glass fiber mat through the feeding hole 15 and the conveying pipe 25.

[0057] Preferably, since the pressure inside the storage box 14 is relatively high when the aerogel is discharged through the conveying pipe 25, when the conveying pipe 25, the feeding hole 15, or the rotating rod 8 is blocked due to impurities or other substances, the pressure can increase the fluidity of the aerogel to clear the blocked pipe, thereby ensuring the best production quality of the aerogel insulation felt.

[0058] Please see Figures 1-4 , Figures 6-8 , Figures 10-12A follow-up translation component is disposed on the storage box 14 and connected to the pressure control component. A sealing plate 24 that cooperates with the storage box 14 is connected to the follow-up translation component. A conveying pipe 25 that cooperates with the feeding hole 15 is disposed on the sealing plate 24. The follow-up translation component includes a support column 21 that is installed on the storage box 14 and is symmetrically arranged. A guide sleeve 22 is slidably installed on the support column 21. A limit plate 23 is provided on the side wall of the guide sleeve 22. A limit groove 2301 is formed on the limit plate 23. It also includes a movable block 34 that is slidably installed in the limit groove 2301. A second connecting rod 33 that is hinged to the movable plate 19 is connected to the movable block 34.

[0059] Furthermore, the limiting groove 2301 can be divided into four sections: a first horizontal groove, a second horizontal groove, a first vertical groove, and a second vertical groove. The first horizontal groove, the first vertical groove, the second horizontal groove, and the second vertical groove are connected end to end and can be combined to form a square shape. In the initial state, under the action of the first spring 20, the movable plate 19 is located at the end of its stroke away from the storage box 14, so that the movable block 34 is controlled by the second connecting rod 33 to be located at the end of its stroke in the direction of the limiting groove 2301 toward the rotating rod 8. At the same time, under the action of the movable plate 19, The guide sleeve 22 and the limiting plate 23 are positioned at the end of their stroke towards the support column 21. At this time, the movable block 34 will be located at the connection position of the first horizontal groove and the second vertical groove. Under the action of the limiting plate 23, the sealing plate 24 controls the conveying pipe 25 to be separated from the feeding hole 15. When it is necessary to convey the aerogel, the aerogel will be gradually conveyed into the storage box 14. As the amount of aerogel conveyed gradually increases, the aerogel will enter the hollow tube 16 through the second feeding groove 13, thereby controlling the movable plate 19 to move towards the lifting support. When the movable plate 19 moves in the direction of plate 2, it also drives the second connecting rod 33 to move, thereby causing the movable block 34 to move along the length of the first transverse groove. Under the action of the movable block 34 and the first transverse groove, the position of the limiting plate 23 is ensured not to change. The movable plate 19 also drives the strength adjustment mechanism to move, so as to change the supporting force on the guide sleeve 22. With the movement of the movable plate 19, under the action of the strength adjustment mechanism, the guide sleeve 22 will tend to move towards the other side of the support column 21. When the movable block 34 moves to the first... When the horizontal groove is connected to the first vertical groove, the strength adjustment mechanism causes the guide sleeve 22 to move toward the other side of the support column 21 and drives the limiting plate 23 to move, so that the movable block 34 moves along the length of the first vertical groove. The limiting plate 23 also drives the sealing plate 24 to move, so as to drive the conveying pipe 25 to move. When the movable block 34 moves to the position where the first vertical groove is connected to the second horizontal groove, the conveying pipe 25 just moves to the position where it matches the feeding hole 15. At this time, the aerogel can be conveyed to the surface of the glass fiber felt through the conveying pipe 25.

[0060] Preferably, after the aerogel is delivered, the amount of aerogel in the storage box 14 gradually decreases, and therefore the pressure also decreases. The first spring 20 is released elastically and drives the movable plate 19 to move toward the initial position. This allows the movable block 34 to move along the length of the second transverse groove via the second connecting rod 33. At the same time, the movable plate 19 also drives the strength adjustment mechanism to move, causing the guide sleeve 22 to tend to move toward the initial position. When the movable plate 19 moves to the initial position, the second connecting rod 33 will control the movable block 34 to move to the connection position between the second transverse groove and the second vertical groove. At this time, under the action of the strength adjustment mechanism, the guide sleeve 22 and the limiting plate 23 move toward the initial position, so that the movable block 34 moves along the length of the second vertical groove until the movable block 34 returns to the connection position between the first transverse groove and the second vertical groove. The above steps are repeated, thereby achieving automatic control of the delivery pipe 25 and the feeding hole 15 after the aerogel output pressure reaches the required level, to ensure the normal delivery of the aerogel.

[0061] Please see Figures 1-4 , Figures 6-8 , Figures 10-12 A strength adjustment mechanism is provided on the pressure adjustment component and connected to the follow-up translation component. The strength adjustment mechanism can adjust the conduction state between the conveying pipe 25 and the feeding hole 15 through the follow-up translation component and the sealing plate 24 when the pressure adjustment component moves. The strength adjustment mechanism includes a first support plate 26 and a second support plate 28 slidably mounted on the support column 21. A second spring 27 and a third spring 29 are sleeved on the support column 21. The two ends of the second spring 27 abut against the first support plate 26 and the guide sleeve 22, respectively. The two ends of the third spring 29 abut against the second support plate 28 and the guide sleeve 22, respectively. A driven component is provided on the movable plate 19 and connected to the first support plate 26 and the second support plate 28. The driven component includes a first connecting rod 30 hinged to the movable plate 19 and hinged to the first support plate 26. A fixed rod 31 is provided on the movable plate 19. A support sleeve 32 sleeved on the fixed rod 31 is provided on the second support plate 28.

[0062] Furthermore, in the initial state, the movable plate 19 is located at the end of its stroke away from the lifting plate 2. Under the action of the movable plate 19, the first support plate 26 is controlled by the first connecting rod 30 to be located at the end of its stroke towards the central axis of the storage box 14. At the same time, the movable plate 19 also controls the second support plate 28 to be located at the end of its stroke away from the central axis of the storage box 14 through the fixed rod 31 and the support sleeve 32. Therefore, the supporting force provided by the second spring 27 to the guide sleeve 22 is greater than the supporting force provided by the third spring 29 to the guide sleeve 22, so that the guide sleeve 22 is located at the end of its stroke towards the support column 21 and has a tendency to move away from the first support plate 26. At this time, the movable block 34 will be located at the connection position between the first horizontal groove and the second vertical groove. When it is necessary to transport the aerogel, as the pressure increases, the movable plate 19 will move towards the lifting plate 2, thereby controlling the movement of the movable block 34 through the second connecting rod 33. The movable block 34 will move along the length direction of the first horizontal groove, and under the action of the movable block 34 and the first horizontal groove, the aerogel will be transported. The position of the guide sleeve 22 is restricted by the limiting plate 23. The movable plate 19 also drives the first connecting rod 30 to move, causing the first support plate 26 to move away from the central axis of the storage box 14. The movable plate 19 also drives the support sleeve 32 to move through the fixed rod 31, causing the second support plate 28 to move towards the central axis of the storage box 14. This reduces the elastic potential energy of the second spring 27 and increases the elastic potential energy of the third spring 29. The guide sleeve 22 tends to move away from the second support plate 28. When the movable block 34 moves to the position where the first horizontal groove and the first vertical groove are connected, the third spring 29 is released elastically and drives the guide sleeve 22 to move toward the other side of the support column 21. Under the action of the guide sleeve 22, the limiting plate 23 is driven to move, so that the movable block 34 moves along the length direction of the first vertical groove. The limiting plate 23 will also drive the sealing plate 24 to move. When the movable block 34 moves to the position where the first vertical groove and the second horizontal groove are connected, the conveying pipe 25 just moves to the position where it is connected with the feeding hole 15. At this time, the aerogel can be conveyed normally.

[0063] Please see Figures 1-4 , Figure 6A negative pressure suction mechanism is disposed on the storage box 14 and connected to the supporting pumping mechanism. The negative pressure suction mechanism can operate when the supporting pumping mechanism moves to adjust the pressure inside the storage box 14. The negative pressure suction mechanism includes a negative pressure tank 35 installed on the storage box 14 and connected to the storage box 14. A second sealing disc 36 is slidably and sealed inside the negative pressure tank 35. A push rod 37 is provided at one end of the second sealing disc 36 away from the storage box 14, penetrating the negative pressure tank 35. A lifting assembly is provided on the rotating rod 8 and connected to the push rod 37. The lifting assembly includes a second annular groove 802 formed on the outer circumference of the rotating rod 8. A connecting plate 38 is slidably installed on the rotating rod 8 and slidably connected to the guide post 9. The connecting plate 38 is connected to the push rod 37. A second limiting block 39 is provided on the inner wall of the connecting plate 38 and slidably fitted with the second annular groove 802.

[0064] To further explain, to prevent residual aerogel from dripping from the conveying pipe 25 after delivery or from clogging it due to prolonged residue, the residual aerogel in the conveying pipe 25 needs to be adsorbed. The second annular groove 802 is also composed of two spiral grooves, with each spiral turning half a turn. Initially, the piston disc 10 is located at the end of its stroke away from the lifting plate 2, and the second limiting block 39 is located at the end of the stroke of the second annular groove 802 away from the lifting plate 2. This causes the connecting plate 38 to also be located at the end of its stroke away from the lifting plate 2. Under the action of the connecting plate 38, the push rod 37 controls the second sealing disc 36 to be located at the end of its stroke away from the storage box 14. At this time, aerogel is adsorbed in the storage box 14. When it is necessary to convey the aerogel, the rotating rod 8 rotates, and the piston is controlled by the first annular groove 801 and the first limiting block 11. The disc 10 moves toward the storage box 14. Simultaneously, under the action of the second annular groove 802 and the second limiting block 39, the connecting plate 38 moves toward the storage box 14, thereby driving the second sealing disc 36 to move through the push rod 37, thus pushing the aerogel in the negative pressure tank 35 into the storage box 14. When the first limiting block 11 moves to the end of the stroke of the first annular groove 801 toward the storage box 14, the second limiting block 39 also moves to the end of the stroke of the second annular groove 802 toward the storage box 14. At this time, the aerogel delivery is completed, and the rotating rod 8 continues to rotate. Under the action of the second annular groove 802 and the second limiting block 39, the connecting plate 38 moves toward the initial position, thereby driving the second sealing disc 36 to move toward the initial position through the push rod 37. A negative pressure will be formed in the negative pressure tank 35 to draw the aerogel remaining in the delivery pipe 25 and the storage box 14 into the negative pressure tank 35.

[0065] A method for producing and molding an aerogel material includes the following steps:

[0066] Step 1: Place the glass fiber mat to be processed on the processing table 1 and transport the area where the aerogel needs to be injected to below the delivery tube 25.

[0067] Step 2: Under the action of the supporting pumping mechanism, the aerogel is transported to the storage box 14 through the piston cylinder 7;

[0068] Step 3: As the amount of aerogel in the storage box 14 gradually increases, the aerogel will enter the hollow tube 16 through the pressurization control component, thereby driving the follow-up translation component to move through the pressurization control component.

[0069] Step 4: The follow-up translation component will also drive the strength adjustment mechanism to move, so as to control the conveying pipe 25 to move to the position that matches the feeding hole 15 through the sealing plate 24. The aerogel in the storage box 14 will be conveyed to the glass fiber mat through the conveying pipe 25.

[0070] Step 5: The supporting pumping mechanism will also drive the negative pressure suction mechanism to move, and after the aerogel pumping is completed, it will adsorb the aerogel remaining in the storage box 14.
