[0003] With the development of the times, the materials industry is constantly updating and iterating, and high-performance, lightweight materials are continuously developed by scientific researchers. Composite materials are materials prepared by compounding two or more materials through adhesives. Composite materials not only have the good performance of composite monomer materials, but also fully combine the excellent performance of different monomers, taking advantage of each other's strengths to achieve a functional 1+1>2 result. In the production and preparation process of composite materials, in order to improve the firmness of the material, after the material is compounded and prepared by adhesives, it usually goes through a aging process. This aging process is to accelerate the curing of the adhesive in a certain temperature environment, promote the internal cross-linking of the adhesive, and enhance the bonding force between the composite monomers.

[0004] The aging process is generally carried out in an aging room. The existing aging room has a publication number of CN213055630U and a patent name of a new type of composite film aging room, which includes a reel for winding the composite film and a aging room body. The two ends of the reel are fixed with connecting parts. The aging room body is provided with a hot air system and a door, and also includes a track, a discharge rack slidably connected to the track, a locking shaft rotatably arranged on opposite sides of the discharge rack, and a locking mechanism arranged on the locking shaft. The above technology still has many problems such as: ① The internal structure is simple, the temperature radiation is uneven, and the temperature near the hot air outlet is relatively high, resulting in inconsistent temperature in the aging room, affecting the aging effect of the product; ② People frequently carry goods in and out of the aging room, which is easy to affect the cleanliness of the aging room, and thus affect the product quality.

It can be understood here that the wall 1 includes the top, three sides around, and the bottom, and the wall 1 and the sealing door together form the outer shell of the curing chamber; an inner partition 2, placed inside the wall 1, the overall size of the inner partition 2 is smaller than that of the wall 1, the inner cavity of the inner partition 2 is a curing cavity 9 for placing the composite coil 8 for curing, and a closed cavity is formed between the inner partition 2 and the inner wall of the wall 1 as an air supply channel 4. The side surface of the inner partition 2 is set as a perforated plate 21. Here, the side surface can be understood as the vertical surfaces of the three sides around, that is, the left, right, and rear walls 1. The perforated plate 21 is made of stainless steel, and a number of air inlet holes 211 are provided on the perforated plate 21. The air inlet holes 211 are arranged in a matrix. A filter screen 3 is installed on the air inlet holes 211, and the filter screen 3 is installed on the perforated plate 21 by clamping or screwing. The filter screen 3 is made of metal. Setting the filter screen 3 is beneficial to filtering dust in the hot air and purifying the hot air. Specifically, the arrangement rule of the air inlet holes 211 on the perforated plate 21 is that the area becomes larger and larger from top to bottom, and the hole spacing of the air inlet holes 211 on the perforated plate 21 becomes smaller and smaller from top to bottom. Specifically, the aperture diameters of each row of air inlet holes 211 from top to bottom are: D1, D2, D3... D n , D n+1 , where D n < D n+1 < 1.2D n , n is a natural number, and the aperture diameter can gradually increase from 5 mm to 25 mm. The hole spacings of the aperture diameters of adjacent two rows of air inlet holes 211 from top to bottom are: L1, L2, L3... L n , L n+1 , where 0.8L n < L n+1 < L n , n is a natural number.

It can be understood here that: the fan 6, the air supply channel 4, the curing cavity 9, and the heating unit 5 are connected in series in turn to form a circulation channel, aiming to make the heat generated by the heating unit 5 enter the curing cavity 9 through the air supply channel 4 and then return to the heating unit 5 for reheating and then enter the air supply channel 4 to form circulating air.

[0037] See the appendix Figure 1 and 2 and 4, further including a conveying assembly 7. The function of the conveying assembly 7 here is to convey and move the composite coil 8 placed in the curing chamber 9 in the curing chamber 9 for one circle and then take it out through the sealing door. The purpose is to make the composite material heat more uniformly and consistently. Specifically, the conveying assembly 7 includes a conveying line placed in the curing chamber 9. The conveying line is used to carry the composite coil 8 and convey it along a specified path so that the composite material is heated evenly in the curing chamber 9. The conveying line includes an upper conveying line 71 and a lower conveying line 72. The upper conveying line 71 is set to feed from the top and discharge from the bottom, and the lower conveying line 72 is set to feed from the bottom and discharge from the top. Both the upper conveying line 71 and the lower conveying line 72 are set as chain conveyors. Bearings are rotatably installed at both ends of the composite coil 8, and teeth for cooperating with the chain are provided on the outer ring of the bearing for limiting both ends of the composite coil 8. Both the upper conveying line 71 and the lower conveying line 72 are set as independent rotary conveyors. The upper layer of the upper conveying line 71 is the upper feeding layer 73, and the lower layer of the lower conveying line 72 is the lower feeding layer 75, that is, the composite coil 8 can be loaded on the upper feeding layer 73 and the lower feeding layer 75. The lower layer of the upper conveying line 71 and the upper layer of the lower conveying line 72 are combined into the middle discharging layer 74. A spring plate 10 is provided at the end of the lower layer of the upper conveying line 71. The spring plate 10 is used for the composite coil 8 on the upper conveying line 71 to enter the middle discharging layer 74. Here, it can be understood that the composite coil 8 on the upper conveying line 71 enters from the upper feeding layer 73 and runs along the upper conveying line 71 until it reaches the end and then enters the middle discharging layer 74 through the spring plate 10. The composite coil 8 on the lower conveying line 72 enters from the lower feeding layer 75 and runs along the lower conveying line 72 until it reaches the end and then enters the middle discharging layer 74. The composite coils 8 on the upper conveying line 71 and the lower conveying line 72 are loaded in a staggered manner. In addition, the setting of the spring plate 10 can be understood as follows: a guiding plate is provided at the end of the upper conveying line 71 away from the sealing door, and guiding plates are also provided below and at the end of the lower conveying line 72 away from the sealing door. The function of the guiding plate is to provide guidance for the composite coil 8 during operation. One end of the spring plate 10 is hinged to the guiding plate at the end of the upper conveying line 71, and the other end is freely set. The hinged part is set as an elastic structure, such as using a spring cylinder to realize the rotation of the spring plate 10 when it is stressed and then return to its original position after the force application ends.

[0038] When the curing chamber of the present utility model is working, a stacker truck is used to sequentially place the composite coils 8 to be cured on the upper conveying line and the lower conveying line of the feeding assembly. The heating unit 5 works to generate heat, and the fan 6 works to blow the heat into the air supply channel 4. The heat enters the curing chamber 9 through the air inlet holes 211 of the orifice plate 21. After the composite coils 8 enter the middle discharging layer 74 from the upper feeding layer 73 and the lower feeding layer 75 respectively driven by the upper conveying line and the lower conveying line, the composite coils 8 are taken from the middle discharging layer 74. After staying in the curing chamber for a certain period of time, the curing operation is completed. After curing the composite material through the curing chamber of the present utility model, the composite coils 8 at various parts in the curing chamber are heated evenly, the product performance is stable, and the curing quality is good. Through the curing group frame, personnel can load and unload the composite coils 8 outside the curing chamber, improving the safety factor and reducing the number of operators entering the curing room, which not only ensures the temperature uniformity in the curing chamber but also avoids the introduction of dust.
