Description

Technical Field

[0002] Aerogel felt is a flexible thermal insulation felt made of nano-silicon dioxide or metal aerogel as the main material, which is compounded with carbon fiber or ceramic glass fiber wool or pre-oxidized fiber felt through a special process. It is characterized by low thermal conductivity, certain tensile and compressive strength, and is a new type of pipeline insulation material.

[0003] In this regard, Chinese patent CN214725680U proposes an aerogel felt mold demoulding device and aerogel production equipment. The aerogel felt mold demoulding device includes a mounting frame, a driving mechanism, an ejection mechanism and a fixing hoop. The fixing hoop is arranged on the mounting frame and is fixed to the mounting frame. The fixing hoop can fix the cylindrical aerogel felt mold. The driving mechanism drives the ejection mechanism to eject in the direction of the fixing hoop, so that the aerogel felt in the aerogel felt mold moves relative to the aerogel felt mold, thereby demoulding the aerogel felt, which is convenient and labor-saving. However, in actual use, since the ejection mechanism simply exerts an action on the aerogel felt, when the aerogel felt is moved by the thrust, it is very likely to cause deformation and breakage due to uneven force.

[0014] A demoulding method for an aerogel felt mold demoulding device comprises the following steps: Step 1: After the aerogel felt is placed in the mold for forming, the ejector plate can be controlled by the ejector assembly to move toward the mold opening to eject the aerogel felt; Step 2: The ejection assembly also drives the follower translation mechanism to move, and controls the translation opening and closing mechanism to move through the rotating assembly, so that the two support plates move toward each other; Step 3: When the side walls of the support plate abut against each other, the mold is sealed under the action of the support plate, and as the ejection plate continues to move, the aerogel felt is placed between the support plate and the ejection plate; Step 4: At this time, the mold opening direction is rotated to the direction of the processing frame, and the ejector assembly continues to control the movement of the ejector plate to make the aerogel felt separate from the mold. At the same time, the ejector assembly also reduces the downward pressure of the support plate on the aerogel felt through the strength control mechanism; Step 5: When the ejection assembly controls the ejection plate to move toward the initial position, the support plates move away from each other under the action of the follow-up translation mechanism until the aerogel felt is separated from the mold.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the present application can ensure that the glass fiber felt will not be damaged due to deformation when it is ejected through the cooperation between the support plate and the ejector plate. When the ejector assembly moves, the glass fiber felt is controlled to move toward the mold opening through the ejector plate. The ejector assembly also drives the rotation assembly to move through the follower translation mechanism, so as to control the two support plates to move toward each other through the horizontal opening and closing mechanism. When the side walls of the two support plates fit together and block the mold opening, the ejector plate continues to move. At this time, the support plate no longer moves. When the ejector plate is When the glass fiber felt is pushed to the position abutting the support plate, the mold can be controlled to flip, and the ejector assembly continues to control the movement of the ejector plate until the glass fiber felt is separated from the mold. At this time, the ejector assembly moves toward the initial position, and controls the horizontal opening and closing mechanism to reset through the follow-up translation mechanism and the rotation assembly to control the support plate to move away. During this process, the ejector plate always provides force to the glass fiber felt in the direction of the support plate to ensure that the glass fiber felt will not be deformed. Until the support plate is separated from the glass fiber felt, the glass fiber felt is separated from the ejector plate under the action of gravity, thereby achieving the demoulding effect.

[0016] When the ejector plate controls the glass fiber mat to be separated from the mold, the ejector assembly will also adjust the squeezing force of the support plate on the glass fiber mat through the strength control mechanism to prevent the glass fiber mat from being damaged due to excessive squeezing force.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. 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.

[0033] See also Figure 1 to Figure 13 In an embodiment of the present invention, an aerogel felt mold demoulding device comprises: A processing frame 1, and a mold 2 rotatably mounted on the processing frame 1; Also includes: See also Figure 1-Figure 5 , Fig. 9 , Fig.11 , an ejection assembly is arranged on the mold 2, and an ejection plate 7 is connected to the ejection assembly and is slidably and sealedly connected to the mold 2. The ejection assembly includes a rotating sleeve 3 rotatably installed at the bottom of the mold 2, a hollow rod 4 penetrating the mold 2 is slidably installed in the rotating sleeve 3, a movable rod 5 is slidably installed in the hollow rod 4, and the movable rod 5 is connected to the ejection plate 7; it also includes a first spring 9 installed in the hollow rod 4 and abutting against the movable rod 5, a connecting plate 6 is provided at the end of the hollow rod 4, and a cylinder 8 connected to the connecting plate 6 is provided on the mold 2.

[0034] In detail, when producing aerogel felt, it is necessary to mix the raw materials in a certain proportion and add the raw materials into the mold 2 containing glass fiber felt. The glass fiber felt will be placed on the surface of the ejector plate 7. After standing for a certain period of time, the surface of the glass fiber felt will gel to form a wet gel fiber felt. At this time, the material needs to be taken out of the mold 2. In the initial state, under the action of the cylinder 8, the hollow rod 4 is controlled by the connecting plate 6 to be located at the end of the stroke away from the mold 2. At the same time, since the ejector plate 7 is subjected to a certain gravity, the first spring 9 is slightly compressed. When ejection is required, under the action of the cylinder 8, the hollow rod 4 is driven to move through the connecting plate 6, thereby driving the movable rod 5 to move through the first spring 9. The movable rod 5 will also drive the ejector plate 7 to move. Under the action of the ejector plate 7, the glass fiber felt placed in the mold 2 is pushed in the direction of leaving the mold 2.

[0035] Preferably, since the size of the ejector plate 7 is the same as the size inside the mold 2, the glass fiber mat will not be deformed when it is pushed, ensuring that it will not be damaged during the demolding process.

[0036] See also Figure 1-Figure 5 , Figure 7-Figure 10 , a follow-up translation mechanism is arranged on the side wall of the mold 2 and connected to the ejection assembly, the follow-up translation mechanism includes a guide column 11 installed on the side wall of the mold 2, a guide sleeve 12 is slidably installed on the guide column 11, a movable plate 13 and a rack plate 16 are arranged on the side wall of the guide sleeve 12, a guide assembly connected to the hollow rod 4 is arranged on the movable plate 13, wherein the guide assembly includes a guide groove opened on the movable plate 13, a guide rod 14 cooperating with the guide groove is rotatably installed on the movable plate 13, a fixed block 15 abutting against the guide rod 14 is arranged on the movable plate 13, and a limiting column 10 slidably engaged with the guide groove is arranged on the hollow rod 4.

[0037] It should be noted that the guide groove can be divided into multiple sections, namely the first straight groove 1301, the first oblique groove 1302, the second straight groove 1303, and the second oblique groove 1304, and one end of the first oblique groove 1302 is connected to the end of the second straight groove 1303, and the other end is connected to the first straight groove 1301, one end of the second oblique groove 1304 is connected to the end of the first straight groove 1301, and the other end is connected to the second straight groove 1303, and two guide rods 14 are provided, one of which is located at the connection position between the first oblique groove 1302 and the first straight groove 1301, and the other is located at the connection position between the second oblique groove 1304 and the second straight groove 1303, and a torsion spring is sleeved on the rotating shaft of the guide rod 14, under the action of the torsion spring, the guide rod 14 is abutted against the fixed block 15.

[0038] In the initial state, under the action of the cylinder 8, the hollow rod 4 is located at the end of the stroke away from the mold 2, and the limit column 10 is located at the end of the stroke on the side of the first straight groove 1301 away from the second inclined groove 1304. When demolding is required, under the action of the cylinder 8, the hollow rod 4 is controlled to move along the length direction of the rotating sleeve 3 to control the glass fiber felt to be demolded through the ejection plate 7. The hollow rod 4 will also drive the limit column 10 to move, so that the limit column 10 slides along the first straight groove 1301. When the limit column 10 moves to the position abutting against one of the guide rods 14, the guide rod 14 will not rotate because it abuts against the fixed block 15.

[0039] Therefore, the limiting column 10 will disengage from the first straight groove 1301 and enter the first inclined groove 1302 to control the guide sleeve 12 to move along the length direction of the guide column 11 through the movable plate 13. The guide sleeve 12 and the guide column 11 have a guiding function to ensure that the movable plate 13 will not deviate during movement. The guide sleeve 12 will also drive the rack plate 16 to move to drive the rotating assembly to move. The rotating assembly will drive the horizontal opening and closing mechanism to move to control the two support plates 28 to move in a direction close to each other. When the limiting column 10 disengages from the first inclined groove 1302 and enters the second straight groove 1303, the movable plate 13 no longer moves, so that the rotating assembly no longer moves. At this time, the two support plates 28 just move to a position where they fit together to seal the opening of the mold 2.

[0040] Preferably, a conveyor belt for receiving the demolding glass fiber felt can be provided under the mold 2, and the ejector plate 7 continues to move and drives the glass fiber felt to continue to move, so that the limiting column 10 moves along the length direction of the second straight groove 1303. When the glass fiber felt moves to a position in contact with the support plate 28, the glass fiber felt will be placed between the support plate 28 and the ejector plate 7 to ensure that the glass fiber felt will not be deformed. At this time, the mold 2 is flipped so that the opening of the mold 2 is facing the processing frame 1, and the cylinder 8 continues to move to control the glass fiber felt to continue to move through the ejector plate 7. When the elastic potential energy of the first spring 9 is greater than the supporting force of the support plate 28, the ejector plate 7 will control the movement of the support plate 28 through the glass fiber felt, so that the glass fiber felt is separated from the mold 2.

[0041] During this process, the limit column 10 will abut against another guide rod 14, causing the guide rod 14 to rotate and separate from the fixed block 15, ensuring that the limit column 10 can continue to slide along the second straight groove 1303. When the limit column 10 is separated from the guide rod 14, the guide rod 14 is reset under the action of the torsion spring. When the limit column 10 moves to the end of the stroke on one side of the second straight groove 1303, the glass fiber felt is completely separated from the mold 2, and the distance between it and the conveyor belt is very small. At this time, the cylinder 8 controls the connecting plate 6 to move toward the initial position, and the first spring 9 is elastically released to control the position of the ejection plate 7 through the movable rod 5 to remain unchanged, so as to always provide downward pressure to the glass fiber felt. At the same time, the limit column 10 will slide along the second straight groove 1303 again.

[0042] When the limiting column 10 moves to the connection position between the second straight groove 1303 and the second inclined groove 1304, the limiting column 10 abuts against the guide rod 14. Under the action of the guide rod 14, the limiting column 10 enters the second inclined groove 1304 to control the guide sleeve 12 to move toward the initial position through the movable plate 13, thereby driving the rack plate 16 to move. Under the action of the rack plate 16, the support plate 28 is controlled to move in the direction away from each other through the rotating assembly and the horizontal opening and closing mechanism until the limiting column 10 disengages from the second inclined groove 1304 and returns to the first straight groove 1301. The support plate 28 returns to the initial position and is no longer in contact with the glass fiber felt. Under the action of gravity, the glass fiber felt will be separated from the ejection plate 7 and fall onto the conveyor belt, thereby achieving a smooth demolding effect.

[0043] See also Figure 1-Figure 7 , Fig. 9 , a rotating assembly is arranged on the side wall of the mold 2 and connected to the follow-up translation mechanism, the rotating assembly includes a first rotating rod 17 rotatably mounted on the mold 2, the first rotating rod 17 is provided with a gear 18 and a first bevel gear 19, the gear 18 is meshed with the rack plate 16; it also includes a second rotating rod 20 and a third rotating rod 22 rotatably mounted on the mold 2, the second rotating rod 20 is connected to the third rotating rod 22 through a first belt 23, and the second rotating rod 20 is provided with a second bevel gear 21 meshed with the first bevel gear 19.

[0044] Furthermore, when the glass fiber felt needs to be ejected, under the action of the limit column 10 and the guide groove, the movable plate 13 is controlled to move to control the movement of the rack plate 16. Under the action of the rack plate 16 and the gear 18, the first rotating rod 17 is controlled to rotate, thereby driving the first bevel gear 19 to rotate. Under the action of the first bevel gear 19 and the second bevel gear 21, the second rotating rod 20 is rotated. The second rotating rod 20 also controls the rotation of the third rotating rod 22 through the first belt 23, so as to control the two support plates 28 to move toward each other through the horizontal opening and closing mechanism. Similarly, when the rack plate 16 moves toward the initial position, the two support plates 28 move toward each other. Move away from each other.

[0045] See also Figure 1-Figure 7 , Fig. 9 , Fig.12 , a horizontal opening and closing mechanism is provided on the rotating assembly, and a symmetrically arranged support plate 28 is connected to the horizontal opening and closing mechanism, and the rotating machine assembly can be actuated when the follow-up translation mechanism moves, and the two support plates 28 are controlled by the horizontal opening and closing mechanism to move toward or away from each other, and the horizontal opening and closing mechanism includes a second spiral groove 2201 provided on the third rotating rod 22, and a symmetrically arranged sliding sleeve 24 is slidably installed on the third rotating rod 22, and a second limit block 2401 slidably engaged with the second spiral groove 2201 is provided in the sliding sleeve 24, and a side wall of the sliding sleeve 24 is provided with a second limit block 2401 slidably engaged with the second rotating rod 20 A guide ring 25 connected to the sliding sleeve 24 is provided with an elastic support component, wherein the elastic support component includes a support sleeve 26 installed on the sliding sleeve 24, a support rod 27 is slidably installed in the support sleeve 26, the support rod 27 is connected to the support plate 28, and a movable ring 30 is slidably installed on the support sleeve 26; it also includes a groove 2601 opened on the support sleeve 26, a limit ring 2701 slidably connected to the groove 2601 is provided on the support rod 27, and a second spring 29 is sleeved on the support sleeve 26, and the two ends of the second spring 29 are respectively abutted against the movable ring 30 and the limit ring 2701.

[0046] Furthermore, in the initial state, the second spring 29 is in a compressed state, so as to control the support rod 27 to be located at the end of the stroke toward the support sleeve 26 through the limit ring 2701, so that the support plate 28 has a tendency to move toward the support sleeve 26, and the second limit block 2401 is located at the end of the stroke on one side of the second spiral groove 2201, so that the distance between the two sliding sleeves 24 is maximized. When the opening of the mold 2 needs to be closed, at this time, the third rotating rod 22 rotates and drives the second spiral groove 2201 to move. 1, the sliding sleeve 24 is driven to move, thereby driving the guide ring 25 to move along the length direction of the second rotating rod 20. Under the action of the guide ring 25 and the second rotating rod 20, it is ensured that the sliding sleeve 24 will not rotate with the third rotating rod 22, and moves along the length direction of the third rotating rod 22. The sliding sleeve 24 will also drive the supporting sleeve 26 to move, thereby controlling the two supporting plates 28 to move towards each other through the supporting rod 27. When the limiting column 10 breaks away from the first inclined groove 1302 and enters the second straight groove 1303, the two supporting plates 28 will abut against each other.

[0047] Preferably, in the initial state, the compression amount of the second spring 29 is greater than the compression amount of the first spring 9. Therefore, when the ejector plate 7 controls the glass fiber mat to abut against the support plate 28, under the action of the connecting plate 6, the size of the hollow rod 4 and the movable rod 5 is controlled to increase, thereby increasing the compression amount of the first spring 9. Before the compression amount of the first spring 9 does not exceed the compression amount of the second spring 29, the ejector plate 7 will not move, so as to provide a certain extrusion force to the glass fiber mat to prevent the glass fiber mat from being deformed when the mold 2 rotates. When the second spring 29 is moved, the ejection plate 7 will drive the support plate 28 to move through the glass fiber felt, so that the support rod 27 moves in the direction away from the support sleeve 26, so as to compress the second spring 29 through the limit ring 2701. At the same time, when the hollow rod 4 moves, it will also drive the strength control mechanism to move, so that when the support plate 28 moves in the direction away from the support sleeve 26, the elastic potential energy of the first spring 9 remains constant, so as to prevent the glass fiber felt from being damaged due to excessive compression of the first spring 9 and the second spring 29, which causes excessive extrusion force on the glass fiber felt.

[0048] See also Figure 1-Figure 9 , Fig.11 , Fig.13, a strength regulating mechanism is arranged on the mold 2 and is connected to the horizontal opening and closing mechanism and the ejection assembly. The ejection assembly can adjust the supporting force of the horizontal opening and closing mechanism on the support plate 28 through the strength regulating mechanism. The strength regulating mechanism includes a vertical groove 401 and a first spiral groove 402 provided on the outer circumferential wall of the hollow rod 4. The ends of the vertical groove 401 and the first spiral groove 402 are connected to each other. A first limit block 301 is provided in the rotating sleeve 3 and is slidably engaged with the vertical groove 401 and the first spiral groove 402. A fourth rotating rod 32 is rotatably installed on the mold 2. The fourth rotating rod 32 is sleeved with a second belt 31 connected to the rotating sleeve 3, and the fourth rotating rod 32 is provided with a lifting assembly connected to the movable ring 30, wherein the lifting assembly includes a third spiral groove 3201 opened on the fourth rotating rod 32, and a movable sleeve 33 is slidably installed on the fourth rotating rod 32, and a third limit block 3301 slidably engaged with the third spiral groove 3201 is provided in the movable sleeve 33, and a regulating plate 34 sleeved on the supporting sleeve 26 is provided on the movable sleeve 33, and the regulating plate 34 abuts against the movable ring 30.

[0049] To elaborate, in the initial state, the hollow rod 4 is located at the end of the stroke away from the mold 2. At this time, the first limit block 301 is located at the end of the stroke on the side of the vertical groove 401 away from the first spiral groove 402, and the third limit block 3301 is located at the end of the stroke on the side of the third spiral groove 3201 away from the support plate 28, so that the distance between the regulating plate 34 and the sliding sleeve 24 is minimized. When the hollow rod 4 moves toward the mold 2, the ejector plate 7 will push the glass fiber felt to move toward the opening direction of the mold 2, and the hollow rod 4 will also drive the vertical groove 401 to move, so that the first limit block 301 slides along the vertical groove 401 to ensure that the fourth rotating rod 32 does not rotate. When the ejector plate 7 controls the glass fiber felt to abut against the support plate 28, the first limit block 301 is still located in the vertical groove In 401, when the elastic potential energy of the first spring 9 exceeds the elastic potential energy of the second spring 29, the ejector plate 7 will control the movement of the support plate 28 through the glass fiber felt. At this time, the first limit block 301 just breaks away from the vertical groove 401 and enters the first spiral groove 402, so that the rotating sleeve 3 rotates, thereby controlling the fourth rotating rod 32 to rotate through the second belt 31. Under the action of the third spiral groove 3201 and the third limit block 3301, the regulating plate 34 moves along the length direction of the fourth rotating rod 32 and moves away from the sliding sleeve 24. Since the support plate 28 is also moving away from the sliding sleeve 24 at this time, the compression amount of the second spring 29 remains unchanged, thereby ensuring that the extrusion force on the glass fiber felt is not too large.

[0050] A demoulding method for an aerogel felt mold demoulding device comprises the following steps: Step 1: After the aerogel felt is placed in the mold 2 for forming, the ejector plate 7 can be controlled by the ejector assembly to move toward the opening direction of the mold 2 to eject the aerogel felt; Step 2: The ejection assembly also drives the follower translation mechanism to move, and controls the translation opening and closing mechanism to move through the rotating assembly, so that the two support plates 28 move toward each other; Step 3: When the side walls of the support plate 28 abut against each other, the mold 2 is sealed under the action of the support plate 28, and as the ejection plate 7 continues to move, the aerogel felt is placed between the support plate 28 and the ejection plate 7; Step 4: At this time, the opening direction of the mold 2 rotates to the direction toward the processing frame 1, and the ejector assembly continues to control the movement of the ejector plate 7 to make the aerogel felt separate from the mold. At the same time, the ejector assembly also reduces the downward pressure of the support plate 28 on the aerogel felt through the strength control mechanism; Step 5: When the ejection assembly controls the ejection plate 7 to move toward the initial position, the support plates 28 move away from each other under the action of the follower translation mechanism until the aerogel felt is separated from the mold 2.
