[0016] 1.

Therefore, the annular expansion sleeve can be automatically expanded and deformed during the closing process of the sealing component, thereby improving the sealing performance of the autoclave.

[0020] 5. The present invention provides a sealing component, an oil storage box, an I-shaped slider and a sliding ring to increase the pneumatic volume that can be pushed when the top block is retracted into the sliding sleeve, so that more air can enter the annular expansion sleeve when the top block is contracted, and an I-shaped slider is provided to increase the force area of ​​the sliding ring to prevent the sliding ring from being squeezed and deformed. The annular expansion sleeve is limited by providing an annular skeleton to prevent the annular expansion sleeve from bending inward when deformed, resulting in a poor sealing effect.

[0021] 6. The present invention provides a material-bearing device, wherein a limit plate passes between two layers of rotating rollers installed on the outside of a triangular bracket, and the bottom of the limit plate contacts the top rotating roller, so that the rotating roller is rotated by the thrust force when the limit plate and the material-bearing plate move, so that the rotating roller assists the material-bearing plate, thereby reducing the friction resistance encountered by the material-bearing plate.

[0022] 7. The present invention provides a material receiving device, and the air spring located on the top of the fixed plate presses the wheel frame downward, so that the clamping wheel is tightly pressed against the surface of the material receiving plate. When the composite material product is placed on the surface of the material receiving plate, the downward pressure of the air spring can prevent the side of the material receiving plate located in the tank body from tilting upward and overturning. At the same time, the air spring is provided to allow the material receiving plate to be slightly deformed when under pressure, thereby preventing the material receiving plate from being damaged when the force is uneven.

[0023] 8. The present invention sets a connecting assembly and connects the limit plate and the receiving plate together by setting a connecting plate, so that the limit plate can provide auxiliary support to the receiving plate, and the two layers of rotating rollers can limit the limit plate, further limiting the movement range of the receiving plate. At the same time, the connecting plate is supported by the triangular block and the arc-shaped support rod, which can prevent the connecting plate from being deformed due to excessive torque, thereby enhancing the structural strength of the connecting plate.

When the sealing assembly 37 is stuck in the limiting slot 5, the hand wheel 374 is turned to make the hand wheel 374 drive the threaded rod 373 to rotate together. At this time, the internal threaded ring 375 can slide along the surface of the threaded rod 373 and approach the inner support plate 372 during the sliding process. During this process, the internal threaded ring 375 pushes the outer support block 377 outward through the connecting rod 376, so that the outer support block 377 slides outward along the limiting sleeve 378.

When the staff puts the composite material product into the tank body 1, the receiving plate 46 can be pulled out of the tank body 1 first, and the receiving plate 46 can drive the limit plate 46 through the connecting assembly 45. 4 slides toward the outside of the tank body 1, and then the composite material product is placed on the surface of the receiving plate 46.

When the composite product is placed on the surface of the receiving plate 46, the downward pressure of the air spring 47 can prevent the side of the receiving plate 46 located in the tank body 1 from tilting upward and overturning. At the same time, the air spring 47 is provided to allow the receiving plate 46 to be slightly deformed when under pressure, thereby preventing the receiving plate 46 from being damaged when the force is uneven.

[0045] Working principle:

[0046] When in use, the tank body 1 is supported by the legs 2, and then the composite material product to be processed is placed above the material receiving device 4 in the tank body 1, and then the tank body 1 is closed by the opening and closing device 3. At this time, the composite material product in the tank body 1 can be subjected to hot pressing and curing molding. The double-layer structure of the tank body 1 and the external insulation layer effectively reduce heat loss and improve energy utilization efficiency.

[0047] When the tank body 1 is closed, the rotating collar 33 is pushed to move by the telescopic cylinder 32 inside the fixing frame 31, and then the position of the sealing assembly 37 is adjusted by rotating the movable rod 35 and the mounting plate 36, so that the sealing assembly 37 can be stuck in the limiting groove 5 provided on the outside of the tank body 1 when it is just opened. In the process of putting the composite material product into the tank body 1, the position of the sealing assembly 37 can be adjusted by contracting the telescopic cylinder 32, so that the sealing assembly 37 can be blocked by the outer edge of the tank body 1 during the swinging process, thereby reducing the rotatable range of the sealing assembly 37, thereby preventing it from hindering the operation of the staff during the feeding process;

[0048] Among them, the compression spring 34 is provided to convert the rigid connection between the telescopic cylinder 32 and the rotating collar 33 into a flexible connection, so as to prevent the sealing assembly 37 from being unable to normally fit into the limiting groove 5 when the hydraulic oil in the telescopic cylinder 32 is injected in excess or in small amounts. At the same time, the movable rod 35 is provided to expand the rotatable range of the sealing assembly 37, thereby improving the flexibility of the sealing assembly 37 when closing the opening of the tank body 1;

[0049] When the sealing assembly 37 is stuck in the limiting groove 5, the hand wheel 374 is turned to make the hand wheel 374 drive the threaded rod 373 to rotate together, and the internal threaded ring 375 can slide along the surface of the threaded rod 373 and approach the inner support plate 372 during the sliding process. During this process, the internal threaded ring 375 pushes the outer support block 377 outward through the connecting rod 376, so that the outer support block 377 slides outward along the limiting sleeve 378. At this time, the outer edge of the outer support block 377 can enter the slot 6. Under the mutual squeezing action of the inclined surface of the outer support block 377 and the inclined surface of the slot 6, the position of the sealing cover 371 can be locked, and then the sealing component 379 is used to seal the interface between the sealing assembly 37 and the tank body 1, thereby preventing hot air from leaking from the interface between the sealing assembly 37 and the tank body 1 during the hot pressing process;

[0050] During this process, the top block 796 first contacts the inner wall of the limiting groove 5, and then under the mutual squeezing of the sealing component 37 and the tank body 1, the top block 796 gradually retracts into the sliding sleeve 795. At this time, the hydraulic oil in the sliding sleeve 795 can enter the oil storage box 798 through the connecting pipe 797, and then the hydraulic oil entering the oil storage box 798 can push the I-shaped slider 799 outward. At this time, the sliding ring 792 slides in the fixed ring 791 together with the I-shaped slider 799, and pushes the air in the fixed ring 791 into the annular expansion sleeve 794. At this time, the air in the annular expansion sleeve 794 increases and the pressure increases, forcing the annular expansion sleeve 794 to expand and fit tightly against the inner wall of the limiting groove 5. In this way, the annular expansion sleeve 794 can be automatically expanded and deformed during the closing process of the sealing component 37, thereby improving the sealing performance of the autoclave.

[0051] The oil storage box 798, the I-shaped slider 799 and the sliding ring 792 are provided to increase the volume of air force that can be pushed when the top block 796 is retracted into the sliding sleeve 795, so that more air can enter the annular expansion sleeve 794 when the top block 796 is retracted, and the I-shaped slider 799 is provided to increase the force area of ​​the sliding ring 792 to prevent the sliding ring 792 from being squeezed and deformed. The annular skeleton 793 is provided to limit the annular expansion sleeve 794 to prevent the annular expansion sleeve 794 from bending inward when deformed, resulting in poor sealing effect.

[0052] When the staff puts the composite material product into the tank body 1, the material receiving plate 46 can be firstly pulled out of the tank body 1, and the material receiving plate 46 can drive the limiting plate 44 to slide toward the outside of the tank body 1 through the connecting assembly 45, and then the composite material product is placed on the surface of the material receiving plate 46, and then the material receiving plate 46 is reset to put the composite material product into the tank body 1. In this process, the limiting plate 44 passes between the two layers of rotating rollers 43 installed on the outside of the triangular bracket 42, and the bottom of the limiting plate 44 contacts the top rotating roller 43, so that the rotating roller 43 is rotated by the thrust when the limiting plate 44 and the material receiving plate 46 move, so that the rotating roller 43 has a boosting effect on the material receiving plate 46, thereby reducing the friction resistance of the material receiving plate 46;

[0053] During this process, the air spring 47 located on the top of the fixed plate 41 presses the wheel frame 48 downward, so that the pressing wheel 49 is tightly pressed against the surface of the receiving plate 46. When the composite material product is placed on the surface of the receiving plate 46, the downward pressure of the air spring 47 can prevent the side of the receiving plate 46 located in the tank body 1 from tilting upward. At the same time, the air spring 47 is provided so that the receiving plate 46 can be slightly deformed when under pressure, thereby preventing the receiving plate 46 from being damaged when the force is uneven.

[0054] Among them, the limit plate 44 and the receiving plate 46 are connected together by setting a connecting plate 451, so that the limit plate 44 can provide auxiliary support to the receiving plate 46, and the two layers of rotating rollers 43 can limit the limit plate 44, further limiting the movement range of the receiving plate 46. At the same time, the connecting plate 451 is supported by the triangular block 452 and the arc support rod 453, which can prevent the connecting plate 451 from being deformed due to excessive torque, thereby enhancing the structural strength of the connecting plate 451.
