The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0027] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0028] A kind of aramid paper honeycomb oven, see Figures 1 to 3 , including an outer shell 1, an inner shell 2, an exhaust pipe 3 and a temperature control mechanism 4, the outer shell 1 has a accommodating space, the top surface of the outer shell 1 is provided with a connecting hole 11 connected to the accommodating space, the inner shell 2 is arranged in the accommodating space, an airway 21 is formed between the outer shell 1 and the inner shell 2, the inner cavity of the inner shell 2 is connected to the airway 21, the exhaust pipe 3 is connected to the top of the outer shell 1, the exhaust pipe 3 is arranged on one side of the connecting hole 11, the exhaust pipe 3 is connected to the airway 21, the temperature control mechanism 4 includes a baffle 41 and a driving component 42, the baffle 41 is movably arranged on the outer shell 1, the baffle 41 has a first position for blocking the connecting hole 11 and a second position for avoiding the connecting hole 11, the driving component 42 is arranged on the outer shell 1, and the driving component 42 provides a driving force for switching the baffle 41 between the first position and the second position.

[0029] The outer shell 1 serves as the main frame, playing a supporting and protective role, and the aramid paper honeycomb is located inside the inner shell 2. Since the outer shell 1 and the inner shell 2 are of different sizes, a gap is formed between the inner shell 2 located inside the outer shell 1 and the outer shell 1, and this gap is the airway 21. The airway 21 is connected to the inner cavity of the inner shell 2 for gas circulation and placement.

[0030] In this embodiment, if Figure 1 As shown, the length direction of the outer shell 1 and the inner shell 2 is the X direction shown in the figure, the width direction of the outer shell 1 and the inner shell 2 is the Y direction shown in the figure, and the height direction of the outer shell 1 and the inner shell 2 is the Z direction shown in the figure.

[0031] The baffle 41 in the temperature control mechanism 4 can block or avoid the connecting hole 11. The connecting hole 11 is mainly used for gas exchange between the airway 21 and the outside. During the gas exchange process, the high-temperature gas in the oven and the low-temperature gas outside are exchanged, which can reduce the temperature in the oven. Driven by the drive component 42, when the temperature needs to be lowered, the baffle 41 avoids the connecting hole 11. When the temperature needs to be kept warm or heated up, the baffle 41 blocks the connecting hole 11 to block the gas exchange between the inside and the outside. Control the cooling rate in the curing and shaping process to achieve energy saving and emission reduction, improve process efficiency, and improve the batch quality consistency of aramid paper honeycomb.

[0032] Furthermore, the aramid paper honeycomb oven further comprises a circulation fan 5 , which is arranged on the top of the outer shell 1 , and the temperature control mechanism 4 is arranged between the circulation fan 5 and the exhaust pipe 3 .

[0033] The circulation fan 5 can play an auxiliary role and accelerate the circulation of air in the airway 21. During the cooling process, the efficiency of gas exchange between the connecting hole 11 and the outside world can be enhanced by turning on the circulation fan 5, thereby improving the cooling effect.

[0034] Furthermore, the temperature control mechanisms 4 are arranged in pairs, and the two temperature control mechanisms 4 arranged in pairs are symmetrically arranged about the exhaust pipe 3 ; the circulation fans 5 are arranged in pairs, and the two circulation fans 5 arranged in pairs are symmetrically arranged about the exhaust pipe 3 .

[0035] When the length of the outer shell 1 is long, the temperature control mechanism 4 alone is difficult to meet the heat dissipation effect of the oven, so the heat dissipation effect of the oven is improved by adding a temperature control mechanism 4. The two temperature control mechanisms 4 arranged in pairs are symmetrically arranged about the exhaust pipe 3, which is convenient for installation. At the same time, due to the symmetrical arrangement, the air circulation effect of the air duct 21 on both sides of the inner shell 2 can be kept consistent, reducing the uneven quality of the honeycomb caused by inconsistent air flow. Similarly, the two circulating fans 5 arranged in pairs are symmetrically arranged about the exhaust pipe 3, also to keep the air circulation effect of the air duct 21 on both sides of the inner shell 2 consistent. By symmetrically arranging the temperature control mechanism 4 and the circulating fan 5 on both sides of the exhaust pipe 3, the consistency of gas circulation in the air duct 21 is guaranteed, and the quality of the product is improved.

[0036] In this embodiment, the baffle 41 is arranged inside the air duct 21, and one end of the baffle 41 is rotatably connected to the outer shell 1. The driving component 42 includes: a first magnetic component 421, and the first magnetic component 421 is arranged on the other end of the baffle 41; a second magnetic component 422, and the second magnetic component 422 is arranged on the outer shell 1. The first magnetic component 421 and the second magnetic component 422 are magnetically attracted to cooperate to drive the baffle 41 to switch between the first position and the second position.

[0037] At least one of the first magnetic member 421 and the second magnetic member 422 is an electromagnet. The temperature control mechanism 4 further includes a controller, which is electrically connected to the electromagnet to control the magnetism of the electromagnet.

[0038] When the controller controls the electromagnet to open, the electromagnet can attract another magnetic part, and the baffle 41 blocks the connecting hole 11 under the drive of the driving component 42; when the electromagnet is closed, the other magnetic part loses the attraction of the electromagnet, and the baffle 41 is separated from the magnetic force of the electromagnet and is in a naturally drooping state. The baffle 41 cannot block the connecting hole 11 and is in an avoidance position. The position of the baffle 41 is switched by the electromagnet, which is convenient for operation.

[0039] Furthermore, the temperature control mechanism 4 also includes an elastic member 43, a first end of the elastic member 43 is arranged on the other end of the baffle 41, and a second end of the elastic member 43 is connected to the outer shell 1. The elastic member 43 provides elastic force for the other end of the baffle 41 to move toward or away from the outer shell 1.

[0040] When the controller controls the electromagnet to close, the baffle 41 should be in a drooping state under the action of gravity, but in some cases, such as the baffle 41 is partially stuck in the connecting hole 11, or the electromagnet still has a small amount of magnetism, etc., the baffle 41 cannot be in the avoidance position. At this time, the elastic member 43 works, and under the elastic force of the elastic member 43, the baffle 41 will move away from the connecting hole 11, ensuring that the baffle 41 is in the avoidance position, increasing the stability of the baffle 41.

[0041] Furthermore, the temperature control mechanism 4 further comprises a sealing member 44 , which is arranged on a surface of the baffle 41 on a side facing the outer shell 1 , and when the baffle 41 is in the first position, the sealing member 44 is in sealing contact with the outer shell 1 .

[0042] When the baffle 41 is in the shielding position, the sealing member 44 can increase the sealing performance of the ground connection between the baffle 41 and the outer shell 1 , thereby improving the sealing effect of the baffle 41 .

[0043] In this embodiment, the temperature control mechanism 4 also includes a base 45, which is arranged on the outer surface of the outer shell 1, and the base 45 is formed into an annular structure arranged along the circumference of the connecting hole 11, and the second magnetic member 422 is arranged on the base 45; the filter screen 46 is arranged on the base 45, and the filter screen 46 covers the connecting hole 11, and is used to allow the air passing through the connecting hole 11 to flow through the filter screen 46.

[0044] The base 45 plays a supporting role in the installation. The base 45 facilitates the installation of the second magnetic member 422 and the filter 46, and avoids installing the filter 46 and the second magnetic member 422 on the outer shell 1, which can facilitate the installation and removal of the filter 46 and the second magnetic member 422. The filter 46 can play a role in drying and filtering. After the air passes through the filter 46, the impurities and water vapor in the air can be reduced, and the influence of water vapor and impurities in the outside air on the product can be reduced.

[0045] In this embodiment, the inner shell 2 also has an air inlet end at the bottom and an air outlet end at the top which are connected to the inner cavity. The air inlet end and the air outlet end are connected to the air duct 21. A partition 22 is provided inside the inner shell 2. The partition 22 divides the inner cavity into an upper cavity connected to the air outlet end and a lower cavity connected to the air inlet end. The partition 22 has a through hole structure which is connected to the upper cavity and the lower cavity.

[0046] Through the air inlet and the air outlet, the inner cavity of the inner shell 2 is connected with the air passage 21, so as to cool the aramid paper honeycomb. The partition 22 divides the inner cavity into an upper cavity and a lower cavity, and the upper cavity and the lower cavity are connected through a through-hole structure. The aramid paper honeycomb is located in the upper cavity, and the partition 22 can play a supporting role. By circulating the gas in this way, the gas circulation will pass through the aramid paper honeycomb, thereby increasing the heat dissipation effect of the aramid paper honeycomb.

[0047] Furthermore, a vertical plate 23 is provided inside the lower cavity, which divides the lower cavity into two independent air inlet cavities spaced apart along the length direction of the outer shell 1, and the air inlet ends are arranged in pairs on two side walls of the inner shell 2 spaced apart along the length direction of the outer shell 1, and the two air inlet ends are respectively connected to the two air inlet cavities.

[0048] By setting the vertical plate 23, the lower cavity can be partitioned, so that after the air in the airway 21 enters the lower cavity, it must pass through the upper cavity before it can be discharged. If there is no vertical plate 23, the air may enter from one end of the lower cavity and be discharged from the other end, and in this process it does not pass through the upper cavity, which affects the heat dissipation effect of the aramid paper honeycomb. By setting the vertical plate 23, the gas must enter the upper cavity, which improves the heat dissipation effect of the aramid paper honeycomb.

[0049] In this embodiment, the aramid paper honeycomb oven further includes an exhaust fan 6, which is disposed on the exhaust pipe 3 and is used to provide a driving force for the gas flow.

[0050] The exhaust fan 6 plays an auxiliary role and is beneficial to the circulation of air.

[0051] The aramid paper honeycomb oven further comprises a heating element 7 , which is arranged inside the air passage 21 . The heating elements 7 are arranged in pairs, and the two heating elements 7 arranged in pairs are arranged in one-to-one correspondence with the two air inlet ends of the inner shell 2 .

[0052] The air in the containing space is heated by the heating element 7 to meet the process requirements of curing and molding.

[0053] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:

[0054] 1. The baffle 41 in the temperature control mechanism 4 can block or avoid the connecting hole 11. The connecting hole 11 is mainly used for gas exchange between the airway 21 and the outside. During the gas exchange process, the high-temperature gas in the oven and the low-temperature gas outside are exchanged, which can reduce the temperature in the oven. Driven by the drive component 42, when the temperature needs to be lowered, the baffle 41 avoids the connecting hole 11. When the temperature needs to be kept warm or heated up, the baffle 41 blocks the connecting hole 11 to block the gas exchange inside and outside. Control the cooling rate in the curing and shaping process, achieve energy saving and emission reduction, improve process efficiency, and improve the batch quality consistency of aramid paper honeycomb.

[0055] 2. The circulation fan 5 can play an auxiliary role and accelerate the circulation of air in the airway 21. During the cooling process, the efficiency of gas exchange between the connecting hole 11 and the outside world can be enhanced by turning on the circulation fan 5, thereby improving the cooling effect.

[0056] 3. When the electromagnet is turned on, it can attract another magnetic part. At this time, the baffle 41 blocks the connecting hole 11 under the drive of the driving component 42; when the electromagnet is turned off, the other magnetic part loses the attraction of the electromagnet. At this time, the baffle 41 is separated from the magnetic force of the electromagnet and is in a naturally drooping state. The baffle 41 cannot block the connecting hole 11 and is in an avoidance position. The position of the baffle 41 is switched by the electromagnet, which is convenient for operation.
