[0002] In the production process of some textiles, fraying and loose fibers often remain on the product surface, affecting the appearance and subsequent packaging quality, such as underwear. Traditional cleaning methods rely on manual labor or simple blowing equipment, which are inefficient and inconsistent in their effectiveness. Existing exhaust systems are mostly used for industrial dust removal, have complex structures, and are unsuitable for the delicate processing of flexible textiles. Therefore, there is an urgent need for an exhaust system specifically designed for textiles such as underwear, which can automatically and efficiently remove fraying, improve product quality, and meet practical usage requirements.

Detailed Implementation

[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0026] This invention provides a negative pressure exhaust device to solve the problem that traditional textile products often have residual fuzz and loose fibers on their surface, which affects their appearance and subsequent packaging quality.

[0027] For ease of understanding, the specific processes in the embodiments of this application are described below. Please refer to [link / reference]. Figures 1 to 5 A negative pressure ventilation device according to an embodiment of this application includes a support 1, a ventilation box 2, an air inlet pipe 3, a filter screen 4, a separating component 5, and a sealing component 6. The ventilation box 2 is mounted on the support 1, and the top of the ventilation box has an exhaust port 20. The air inlet pipe 3 communicates with the ventilation box 2 and is used to connect to an external ventilation device. One end of the filter screen 4 is disposed on the side wall inside the ventilation box, and the other end is disposed on the other side wall of the ventilation box 2, thereby dividing the ventilation box into two parts. The separating component 5 is disposed through the air inlet pipe 3, dividing the air inlet pipe 3 into two sections. The separating component 5 has a slot 50, and a through hole 51 is provided along the vertical direction of the slot 50, and the through hole 51 connects the two sections of the air inlet pipe. The sealing component 6 is retractably disposed on the support, and when the sealing component extends forward, it can completely seal the through hole.

[0028] During operation, the sealing component 6 is in a retracted state, and the sealing component 6 does not seal the through hole 51. At this time, the air inlet duct 3 is connected to the external exhaust equipment. After the exhaust equipment is turned on, there is suction at the exhaust port 20. The product is manually placed at the exhaust port 20, and the suction generated at the exhaust port 20 is used to absorb the loose lint and surface fibers of the product into the exhaust box 2. After the lint and other waste materials enter the exhaust box 2, they are filtered out by the filter screen 4. The waste materials remain on the left side of the filter screen 4, and the air is blown out from the air inlet duct 3. After a period of time, the lint and surface fibers of the product have been sucked into the exhaust box 2.

[0029] When not in use, the sealing component 6 moves into the slot 50 and seals the through hole 51, thereby isolating the external exhaust device and the exhaust box 2. As a result, no suction is generated at the exhaust port 20, and the device is in a non-working state.

[0030] Furthermore, the exhaust box 2 has a shape that is small at the top and large at the bottom. This structure can enhance the suction power, thereby making it more effective at removing lint and loose fibers from the product surface.

[0031] Furthermore, the exhaust port 20 is also provided with eaves 7 extending outward from both ends of the bottom of the exhaust box 2. Due to the presence of the two eaves 7, the product can be easily sucked into the exhaust port.

[0032] Furthermore, to facilitate the removal of waste materials such as lint from the exhaust box 2, a material inlet 21 is provided on the side of the exhaust box 2 opposite to the air inlet duct 3. The material inlet 21 is covered by a material inlet panel 8, which is movably mounted via a movable mechanism. This movable mechanism includes a rotating shaft 9 and a limiting shaft 10 located on both sides of the material inlet 21. One end of the material inlet panel 8 is rotatably connected to the rotating shaft 9, and the other end is secured to the limiting shaft 10 via a slot 11 on the material inlet panel. The slot 11 is U-shaped, allowing the limiting shaft 10 to be secured within the U-shaped slot, thus fixing the material inlet panel 8. When the material inlet panel 8 needs to be fixed, it is rotated clockwise, and then secured by the matching of the limiting shaft 10 and the U-shaped slot 11. When the movable panel needs to be opened, it is simply rotated counterclockwise around the rotating shaft 9 to open, facilitating the removal of waste materials.

[0033] The bracket 1 is equipped with a telescopic cylinder 12 connected to the sealing component 6; the telescopic cylinder 12 drives the sealing component 6 to move back and forth within the slot 50, and other driving methods can also be used.

[0034] This utility model's negative pressure exhaust device, when it needs to adsorb burrs, does not block the through hole with the sealing component. It uses an external exhaust device to adsorb the burrs of the product located at the exhaust port into the exhaust box. After the burr waste is filtered by the filter screen, the waste remains in the exhaust box and is automatically collected. Then, the waste is taken out from the dispensing port through the movable material dispensing panel, achieving efficient adsorption and convenient waste cleaning. The overall structure is simple and easy to operate, and it is suitable for automated packaging lines, significantly improving the quality and efficiency of product packaging.

[0035] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
