[0021] Please see Figures 1 to 5 As shown in the figure, this application provides a cooling mechanism for a hot-melted composite fabric, which includes a frame 10, a conveyor belt (not shown), a drive assembly 20, and a cooling assembly 30. The conveyor belt is rotatably mounted on the frame 10 and is configured to receive the hot-melted composite fabric. The drive assembly 20 is configured to drive the conveyor belt to rotate, thereby moving it along a first horizontal direction (…). Figure 1 (In the direction of X) the conveyor belt carries the hot-melted composite fabric; the conveyor belt has multiple ventilation holes evenly distributed on its body; the cooling component 30 is set on the frame 10 and located between the upper and lower belt bodies of the conveyor belt; the air extraction end of the cooling component 30 is set upward; the cooling component 30 is configured to draw air from above the hot-melted composite fabric carried on the conveyor belt through the air extraction end, so that the air above the conveyor belt flows quickly through the hot-melted composite fabric, thereby cooling and solidifying the hot-melted composite fabric.

[0022] By combining a cooling component 30 with its exhaust end facing upwards and a conveyor belt with multiple vents evenly distributed, air above the conveyor belt flows quickly through the composite fabric, increasing the cooling speed of the composite fabric after hot melting.

[0023] In one embodiment, the cooling assembly 30 includes a cooling duct 31 and at least one set of exhaust components (not shown in the figure), wherein: the cooling duct 31 is along a second horizontal direction ( Figure 1The cooling duct 31 extends in the Y direction and the exhaust end of the cooling duct 31 faces upward. The exhaust component is connected to the cooling duct 31 and is configured to extract air from the cooling duct 31, thereby extracting air above the hot-melted composite fabric through the exhaust end of the cooling duct 31.

[0024] Specifically, the first horizontal direction is perpendicular to the second horizontal direction.

[0025] Specifically, the air extraction component includes an air pump and an air extraction pipe. The air pump is connected to the cooling air duct 31 through the air extraction pipe and extracts air from the cooling air duct 31 through the air extraction pipe, providing a stable air extraction component.

[0026] Specifically, the cooling assembly 30 includes two sets of air extraction components. The two sets of air extraction components are respectively arranged on both sides of the frame 10 extending along the first horizontal direction and are connected to the cooling air duct 31, so that the entire cooling area forms a double-sided symmetrical air extraction layout. While enhancing the symmetry of airflow, it also enhances the negative pressure at the extraction end, thereby enhancing the air velocity and further improving the cooling efficiency.

[0027] By cooperating with the cooling air duct 31 and the air extraction component, directional suction of air above the composite fabric is achieved, enhancing the controllability of airflow and further improving the stability of cooling.

[0028] In one embodiment, the exhaust end of the cooling air duct 31 is provided with a plurality of air distribution plates 32, which extend along the second horizontal direction and have a plurality of air distribution holes 323 evenly distributed on them.

[0029] By setting a uniform air distribution plate 32 at the exhaust end of the cooling air duct 31, a uniform negative pressure is provided below the upper side of the conveyor belt, thereby allowing air to pass through the composite fabric and the conveyor belt evenly, thus improving the uniformity of cooling of the composite fabric.

[0030] In one embodiment, the cooling air duct 31 includes a main air duct 310, a first side air duct 311, and a second side air duct 312, wherein: the main air duct 310 extends along a second horizontal direction, the first side air duct 311 is disposed on a first side of the main air duct 310 extending along the second horizontal direction, and the second side air duct 312 is disposed on a second side of the main air duct 310 extending along the second horizontal direction, and the main air duct 310 is connected to the first side air duct 311 and the second side air duct 312 along the first horizontal direction.

[0031] Specifically, the exhaust end specifications of the main air duct 310, the first side air duct 311, and the second side air duct 312 are all the same, which is conducive to the balanced distribution of gas through the conveyor belt and composite fabric.

[0032] By coordinating the main air duct 310, the first side air duct 311, and the second side air duct 312, the gas is ensured to flow stably in the preset direction, while the airflow distribution range is improved, further enhancing the cooling efficiency and cooling effect.

[0033] In one embodiment, the air distribution plate 32 is spaced apart along the first horizontal direction at the air extraction end of the corresponding air duct and covers the corresponding air duct.

[0034] Specifically, the exhaust end of each air duct has the same specifications and is equipped with a corresponding air distribution plate 32. The air distribution plate 32 includes a first plate 320 and a second plate 321. The first plate 320 and the second plate 321 are arranged side by side along the second horizontal direction and are connected by bolt assembly, which improves the installation flexibility of the air distribution plate 32.

[0035] By setting the air distribution plates 32 on the same horizontal plane, the air extraction end of the corresponding air duct and the conveyor belt maintain the same preset distance, which further improves the uniformity of air flow.

[0036] In one embodiment, the drive assembly 20 includes a drive member 21, a drive roller 22, and a driven roller 23, wherein the drive roller 22 and the driven roller 23 are rotatably mounted on the frame 10 at intervals along a first horizontal direction, and the conveyor belt is rotatably mounted on the drive roller 22 and the driven roller 23; the fixed end of the drive member 21 is mounted on the frame 10, and the drive end of the drive member 21 is connected to the drive roller 22. The drive member 21 is configured to drive the drive roller 22 to rotate, and then drive the conveyor belt to rotate through the cooperation of the driven roller 23.

[0037] Specifically, the drive component 21 is a motor.

[0038] By cooperating with the driving component 21, the driving roller 22 and the driven roller 23, a driving assembly 20 with a simple structure and stable and controllable drive is provided.

[0039] In one embodiment, a support plate 313 is provided at the connection between the main air duct 310 and the first side air duct 311 and the connection between the second side air duct 312. The support plate 313 extends along the second horizontal direction, and the height of the support plate 313 in the vertical direction is not higher than the top height of the roller surface of the active roller 22. The support plate 313 is configured to support the upper belt of the conveyor belt.

[0040] Specifically, the vertical height of the support plate 313 is higher than the installation height of the air distribution plate 32, so that the upper belt of the conveyor belt maintains a certain distance from the air distribution plate 32, which is conducive to the balanced flow of gas.

[0041] By setting a support plate 313 at the air duct connection, a stable support is provided for the upper belt of the conveyor belt, preventing the fabric from sinking excessively due to wind pressure or its own weight, thereby ensuring the flatness and process stability of the composite fabric during cooling.

[0042] In one embodiment, the support plate 313 has inclined surfaces 3130 extending on both sides along the second horizontal direction, and the inclined surfaces 3130 are inclined downwards.

[0043] By setting inclined surfaces 3130 at both ends of the support plate 313, a guiding transition is formed when the conveyor belt contacts the support plate 313. This not only avoids damage to the conveyor belt caused by the support plate 313, but also reduces friction between the conveyor belt and the support plate 313, thus improving the smoothness of the conveyor belt's operation.

[0044] In one embodiment, the drive assembly 20 further includes a tension roller assembly disposed below the cooling duct 31 and abutting against the inner side of the lower layer of the conveyor belt, the tension roller assembly being configured to tension the conveyor belt.

[0045] Specifically, the first tension roller 24 and the second tension roller 25 are rotatably mounted on the frame 10 at intervals along a first horizontal direction. The first tension roller 24 is located diagonally below the side of the driving roller 22 near the driven roller 23, and the second tension roller 25 is located diagonally below the side of the driven roller 23 near the driving roller 22. Both the first tension roller 24 and the second tension roller 25 abut against the lower side of the conveyor belt, providing a tension roller assembly with a stable structure.

[0046] By setting up tension rollers that abut against the lower layer of the conveyor belt, continuous tension control of the conveyor belt can be achieved, preventing belt deviation or fabric wrinkling due to slack during operation and improving overall operational stability.

[0047] The working principle of the cooling mechanism for the composite fabric after hot melting is as follows: S1, the driving component 21 drives the active roller 22 to rotate so as to drive the conveyor belt to rotate through the cooperation of the driven roller 23, thereby causing the hot-melted composite fabric carried by the conveyor belt to move along the first horizontal direction to the top of the exhaust end of the cooling air duct 31. S2, the air extraction component draws air from the main air duct 310, and at the same time draws air from the first side air duct 311 and the second side air duct 312 through the main air duct 310, so as to form a negative pressure at the air extraction end of the corresponding air duct. S3, the air above the conveyor belt flows quickly through the composite fabric and the conveyor belt, and then enters the corresponding air duct through the air distribution hole 323, thereby cooling and curing the composite fabric.

[0048] A composite fabric hot-melt device, comprising any one of the above-mentioned cooling mechanisms for the composite fabric after hot-melt.

[0049] The above embodiments merely illustrate the basic principles and characteristics of this application. This application is not limited to the above examples.
