Description

Technical Field

[0001] The invention relates to the field of aerogel sheet production, in particular to a production device and a production method of an aerogel thin plate sheet. Background Art

[0002] Aerogel sheet is a material with high porosity, ultra-low density and excellent thermal insulation performance. Its production design has multiple steps, including stacking, dipping, curing, etc. The Chinese patent (authorization announcement number: CN115230205B) proposes an aerogel sheet manufacturing device. After the PVC box on the chain conveyor line completes the dipping and curing process, the clamping device tightens the partition during the return process of the chain conveyor line to achieve automatic demoulding. At the same time, the gel cotton block with good gel curing automatically falls onto the separation conveyor chain under the action of deadweight or tension to achieve demoulding. The clamping device includes a first clamp, a second clamp and a clamping drive component. The clamping drive component is electrically connected to the control device. The first clamp and the second clamp are arranged on both sides of the chain conveyor line. The clamping drive component is connected to the first clamp and the second clamp to drive the first clamp and the second clamp to clamp the gel cotton block in the PVC box and transfer it to the separation conveyor chain. Preferably, the number of the first clamps and the number of the second clamps are plural, for example, the number of the first clamps and the number of the second clamps are two respectively, and the two first clamps and the two second clamps clamp the four corners of the partition respectively.

[0003] Although the above patent can realize the demoulding function, a large number of clamps need to be set up, and since the entire demoulding process is relatively complicated, when it is implemented, the control device therein needs to rely on more complex logic programming in order to control the movement of multiple clamps and the execution of the clamping action. However, when the programming fails, the movement of multiple clamps loses coordination, resulting in the demoulding process may not be completed smoothly, causing losses in the production process.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0027] See also Figure 1-Figure 9 In an embodiment of the present invention, a production device for aerogel sheet material includes a chain plate conveyor line, a partition conveyor line, a cotton block conveyor line, a first stacking device, a vacuum dipping device, a curing device, a clamping device, a separation conveyor chain, a breathable net conveyor line, a steel plate conveyor line and a second stacking device; The clamping device is arranged at the end of the chain conveyor line, and is used to separate the gel cotton block in the PVC box on the chain conveyor line from the flexible partition, and transfer the gel cotton block to the separation conveyor chain. The clamping device includes a frame 1 and two sets of mounting arm groups respectively arranged on both sides of the frame 1 and arranged oppositely. The mounting arm group includes two cross arms 2 arranged on one side of the frame 1. The production equipment of the aerogel thin plate sheet also includes: A transverse block 5 is movably arranged on the cross arm 2 and can be driven by a threaded driving mechanism arranged on the cross arm 2 to move along the length direction of the cross arm 2. The transverse block 5 is connected to a pulling mechanism through an elastic connection mechanism, and the pulling mechanism is connected to a clamping mechanism. When the clamping mechanism reaches below the chain plate conveyor line, the clamping mechanism can clamp the flexible partition. Then, the pulling mechanism is triggered, prompting the clamping mechanism to tighten the flexible partition, so that the gel cotton block is separated from the flexible partition and falls onto the separation conveyor chain; The swing mechanism is arranged on the frame 1, and is triggered when the clamping mechanism clamps or releases the flexible partition. When the clamping mechanism releases the flexible partition, the swing mechanism can perform a downward swinging action to perform a peeling action on the flexible partition.

[0028] Specifically, during operation, a plurality of PVC boxes are installed on the chain conveyor line, the first stacking device is used to place the flexible partitions conveyed by the partition conveyor line and the cotton blocks conveyed by the cotton block conveyor line into the PVC boxes, the vacuum impregnation device is arranged above the chain conveyor line to perform vacuum and glue injection on the PVC boxes on the chain conveyor line, and the curing device is arranged above the chain conveyor line to perform curing on the PVC boxes after glue injection on the chain conveyor line; During the return process of the chain conveyor line, the clamping device works. First, the threaded drive mechanism drives the transverse block 5 to move along the length direction of the cross arm 2, and the transverse block 5 drives the clamping mechanism toward the bottom of the chain conveyor line through the elastic connection mechanism and the pulling mechanism. After the clamping mechanism reaches the end of the stroke, the clamping mechanism is triggered to perform a clamping action on the flexible partition. Then, the transverse block 5 and the pulling mechanism move relative to each other, so that the pulling mechanism prompts the clamping mechanism to perform a pulling action on the flexible partition. As a result, the flexible partition is tightened. Under the action of tension and gravity, the gel cotton block on the flexible partition falls onto the separation conveyor chain, completing the transfer process of the gel cotton block. Subsequently, the threaded drive mechanism works in the reverse direction, and the clamping mechanism drives the flexible partition to move to the side of the chain conveyor line. After the clamping mechanism releases the clamping state of the flexible partition, the swing mechanism peels the flexible partition off the clamping mechanism. The second stacking device is used to stack the steel plates conveyed by the steel plate conveyor line, the breathable nets conveyed by the breathable net conveyor line, and the gel cotton blocks to form stacked products.

[0029] It should be pointed out that the flexible partition plays a role in supporting and fixing the substrate during the manufacturing process. After being peeled off by the swing mechanism, the flexible partition may be used in the subsequent stacking device and stacked with other materials such as steel plates, breathable nets, etc. to form the final product. In addition, the flexible partitions may also be reused because they have certain elasticity and compressibility and can be compressed by 10-90% under a certain pressure. Therefore, after being separated from the cotton block, the flexible partition may be used as part of the stacking product, or be reused according to specific process requirements.

[0030] Please refer again Figure 2 and Figure 4 The cross arm 2 is fixed with a guide rail 6, the transverse block 5 is slidably engaged with the guide rail 6, and the threaded drive mechanism includes a screw rod 4 rotatably mounted on the cross arm 2 and a drive motor 3 mounted on the cross arm 2. The screw rod 4 is connected to the output end of the drive motor 3, and the screw rod 4 passes through the transverse block 5 and is threadedly connected to the transverse block 5. Two limiting protrusions 601 cooperating with the pulling mechanism are fixedly provided on the guide rail 6.

[0031] During operation, the driving motor 3 drives the screw rod 4 to rotate, and the guide rail 6 guides the transverse block 5, so that the transverse block 5 is threadedly matched with the screw rod 4 and slides along the guide rail 6. Correspondingly, the clamping mechanism moves toward the bottom of the chain conveyor line to reach a position suitable for clamping the flexible partition. After the clamping mechanism reaches the end of the row, the pulling mechanism cooperates with the limiting protrusion 601, and the transverse block 5 continues to move. At this time, the pulling mechanism is triggered, so that the clamping mechanism tightens the flexible partition to promote the separation of the gel cotton block and the flexible partition. The threaded match between the screw rod 4 and the transverse block 5 is used to realize the position movement of the clamping mechanism, and the driving accuracy is high and the stability is good.

[0032] Please refer again Figure 5 , Figure 8 as well as Fig. 9 The elastic connection mechanism includes a cross bar 7 arranged on the transverse block 5, a connecting plate 18 slidably connected to the cross bar 7, and a first vertical plate 9 connected to the connecting plate 18, and the pulling mechanism is connected to the first vertical plate 9; a first cylindrical spring 8 is sleeved on the outer periphery of the cross bar 7, one end of the first cylindrical spring 8 is connected to the connecting plate 18, and the other end is connected to the ring body 701 arranged on the cross bar 7, and two strip protrusions 1801 that cooperate with the limiting protrusion 601 are formed on the end of the connecting plate 18 away from the first vertical plate 9. Two guide posts 10 are fixed to one side of the first vertical plate 9 away from the connecting plate 18, the pulling mechanism includes two sliders 12 respectively slidably arranged on the two guide posts 10 and a second vertical plate 13 connecting the two sliders 12, the clamping mechanism is arranged on the second vertical plate 13, and can move along the length direction of the second vertical plate 13; one end of the cross bar 7 away from the transverse block 5 is connected to the slider 12 through a connecting rod 11, one end of the connecting rod 11 is rotatably connected to the slider 12, and the other end is rotatably connected to the cross bar 7.

[0033] When the threaded drive mechanism drives the transverse block 5 to move along the guide rail 6 toward the chain conveyor line, the transverse block 5 first uses the supporting force of the first columnar spring 8 to drive the connecting plate 18, the first vertical plate 9 and the second vertical plate 13 to move together. After the clamping mechanism reaches the bottom of the chain conveyor line and is suitable for clamping the flexible partition, the strip protrusion 1801 abuts against the limiting protrusion 601. At this time, the clamping mechanism is triggered to clamp the flexible partition, and the transverse block 5 continues to move. Under the limiting action of the limiting protrusion 601, the connecting plate 18 remains stationary, so the transverse block 5 gradually approaches the connecting plate 18, the cross bar 7 slides on the connecting plate 18, the first columnar spring 8 is compressed, and the cross bar 7 pulls the slider 12 on the guide column 10 toward the first vertical plate 9 through the connecting rod 11. Therefore, the two sets of clamping mechanisms located on the frame 1 are away from each other, which can tighten the flexible partition, causing the gel cotton block to detach from the flexible partition and fall onto the separation conveying chain.

[0034] The clamping mechanism includes two clamping arms 14 symmetrically and slidably arranged on the second vertical plate 13 and a column 15 arranged on the second vertical plate 13, the column 15 passes through the two clamping arms 14 and is slidably connected to the clamping arms 14, and the clamping arm 14 is connected to a second cylindrical spring 16 sleeved on the outer periphery of the column 15, and the end of the second cylindrical spring 16 away from the clamping arm 14 is connected to a boss 1501 fixedly arranged at the end of the column 15, and the two clamping arms 14 are also each connected to a set of limiting structures.

[0035] The limiting structure includes a limiting plate 19 disposed on the frame 1, a horizontal column 17 is fixed to the side of the clamping arm 14 facing the limiting plate 19, the horizontal column 17 passes through the first vertical plate 9, and the first vertical plate 9 is provided with a through slot 901 for the horizontal column 17 to move; Among them, the upper groove body of the limiting plate 19, the cross column 17 extends into the groove body, and the groove body includes a first groove 1901, a second groove 1902, a third groove 1903, a fourth groove 1904 and a fifth groove 1905 that are connected to each other. The fifth groove 1905 is connected to the connection between the first groove 1901 and the second groove 1902, and a movable part 20 is rotatably provided in the limiting plate 19, and the movable part 20 is connected with an elastic sheet and is located at the connection between the first groove 1901, the second groove 1902 and the fifth groove 1905.

[0036] Specifically, the first groove 1901 and the second groove 1902 are collinear, the fourth groove 1904 is parallel to the first groove 1901 and the second groove 1902, the third groove 1903 is perpendicular to the second groove 1902 and the fourth groove 1904, and the fifth groove 1905 is inclined. When the clamping arm 14 moves toward the lower part of the chain conveyor line, the cross column 17 moves along the first groove 1901 and the second groove 1902 in sequence. When the clamping arm 14 reaches the end of the stroke, that is, the cross column 17 reaches the connection between the second groove 1902 and the third groove 1903, the second cylindrical spring 16 in the compressed state rebounds, causing the two clamping arms 14 to approach each other and clamp the flexible partition. Accordingly, the cross column 17 is transferred from the connection between the second groove 1902 and the third groove 1903 to the connection between the third groove 1903 and the fourth groove 1904. After the flexible partition is tightened and the gel cotton block is separated from the flexible partition, the threaded drive mechanism works in the reverse direction, the transverse block 5 first moves away from the connecting plate 18, the first column spring 8 rebounds, and then the connecting plate 18 moves with the transverse block 5 and gradually returns to its original position. During this process, the cross column 17 first moves along the fourth groove 1904, and when the cross column 17 moves along the fifth groove 1905, it will cause the clamping arm 14 to give way. Specifically, the two clamping arms 14 slide away from each other on the second vertical plate 13 to release the clamping state of the flexible partition. Finally, the cross column 17 causes the movable part 20 to swing toward the first groove 1901 and the second groove 1902, and the cross column 17 enters the first groove 1901 and returns to the end of the first groove 1901 away from the second groove 1902. Furthermore, the movable part 20 is set for unidirectional rotation in the limiting plate 19. The purpose of its setting is that when the threaded drive mechanism works in the forward direction, the cross column 17 can enter the second groove 1902 from the first groove 1901, so as to prevent the cross column 17 from entering the fifth groove 1905. When the threaded drive mechanism works in the reverse direction, the cross column 17 moves along the fifth groove 1905, so that the movable part 20 can be deflected and the elastic sheet therein can be deformed. After the cross column 17 is separated from the movable part 20, the elastic sheet can prompt the movable part 20 to deflect in the reverse direction and reset.

[0037] It should be emphasized that after the clamping arm 14 clamps the flexible partition, the clamping arm 14 will tighten the flexible partition during the compression of the first cylindrical spring 8. At this time, the cross column 17 will move toward the groove on the limiting plate 19. For this purpose, the groove should have a certain depth. Secondly, the width of the fourth groove 1904 is relatively large. When the second cylindrical spring 16 rebounds, the clamping arm 14 clamps the flexible partition. At this time, the cross column 17 does not contact the inner wall of the second groove 1904, ensuring that the elastic force of the second cylindrical spring 16 can smoothly act on the flexible partition through the clamping arm 14.

[0038] Please refer again Figure 3 , Figure 4 as well as Figure 7 The swing mechanism includes a sliding fit component installed on the frame 1 and a transmission structure connecting the sliding fit component and the clamping arm 14. The transmission structure includes a slide plate 23 slidably arranged on the frame 1, a guide cylinder 24 arranged on the slide plate 23, and a telescopic rod 25 slidably fitted with the guide cylinder 24. A transmission arm 22 is fixed to the end of the telescopic rod 25 away from the slide plate 23. A follower arm 21 is slidably fitted on both ends of the transmission arm 22. The follower arm 21 is fixed to the clamping arm 14 located above.

[0039] The sliding fitting assembly includes a driven shaft 26 rotatably mounted on the frame body 1 and a sleeve 27 slidably mounted on the driven shaft 26, a boss is provided on the inner wall of the sleeve 27, and a slide groove 2601 adapted to the boss is provided on the outer periphery of the driven shaft 26; the slide groove 2601 is spirally arranged, the boss extends into the slide groove 2601 and is slidably connected to the driven shaft 26, the sleeve 27 is connected to the guide cylinder 24 through a support rod 28, and the two ends of the support rod 28 are respectively hinged to the sleeve 27 and the guide cylinder 24, and a swing arm 29 is fixedly provided at each end of the driven shaft 26.

[0040] Please see attached Figure 1 At this time, the height of the swing arm 29 away from the driven shaft 26 is lower than the two clamping arms 14 located below the frame 1; When the clamping arm 14 clamps the flexible partition, the slide plate 23 is driven to slide downward on the frame body 1 through the follower arm 21, the transmission arm 22, the telescopic rod 25 and the guide cylinder 24. Correspondingly, the guide cylinder 24 drives the sleeve 27 to slide on the driven shaft 26 along the length direction of the driven shaft 26 through the support rod 28, and the protruding column slides with the driven shaft 26 through the slide groove 2601, thereby causing the driven shaft 26 to rotate, and the swing arm 29 swings upward, and the end away from the driven shaft 26 is higher than the two clamping arms 14 located below the frame body 1; When the clamping arm 14 is in the process of tightening the flexible partition, the follower arm 21 slides on the transmission arm 22. In the latter part of the stroke of the clamping arm 14 resetting, the clamping arm 14 releases the clamping state of the flexible partition. At this time, the slide plate 23 slides upward on the frame 1, and the boss again slides with the driven shaft 26, prompting the driven shaft 26 to drive the swing arm 29 to swing downward, thereby peeling off the flexible partition on the clamping arm 14 below, so as to complete the collection of the flexible partition, and use it in the subsequent stacking device, stacked together with other materials such as steel plates, breathable nets, etc. to form the final product or be reused.

[0041] As another embodiment of the present invention, a method for producing an aerogel sheet is also proposed, using the production equipment, comprising the following steps: Step 1: The first stacking device places the flexible partitions conveyed by the partition conveyor line and the cotton blocks conveyed by the cotton block conveyor line into the PVC box on the chain conveyor line; Step 2: The vacuum dipping device performs vacuuming and glue injection on the PVC box body, and the curing device performs a curing treatment on the glue-injected PVC box body; Step 3: The clamping device works during the return process of the chain conveyor line to clamp and tighten the flexible partition, so that the gel cotton block falls onto the separation conveyor chain, and the flexible partition is transferred to the collection end; Step 4: The second stacking device stacks the steel plates conveyed by the steel plate conveyor line, the breathable nets conveyed by the breathable net conveyor line, and the gel cotton blocks to form stacked products.

[0042] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
