Description

Technical Field

[0001] This utility model relates to the field of textile manufacturing, specifically to an exhaust device for a cashmere fabric production line. Background Technology

[0002] Textile manufacturing refers to the production activities of woven products made of cotton, chemical fibers, wool, linen, and silk. Cashmere textiles generate lint during the manufacturing process. Workers typically wear masks to avoid inhaling this lint, but excessive lint can enter their ears and eyes, causing harm. Therefore, workshops need ventilation systems to remove the lint-laden air. This is usually achieved by installing exhaust fans at the vents. However, existing exhaust fans only provide ventilation; the lint removed from the workshop can actually pollute the outside environment. To avoid this, exhaust fans with filters are used. However, these fans have filters inside the fan itself, which accumulate lint after a period of use, requiring cleaning or replacement. But because exhaust fans have complex structures, disassembly is very inconvenient, and reassembly after cleaning is even more difficult, often resulting in damage to components during assembly, significantly impacting the normal operation of the exhaust fans. Summary of the Invention

[0003] In order to solve one or more technical problems existing in the prior art, the purpose of this application is to provide an exhaust device for a cashmere fabric production line, which has a simple structure, is easy to disassemble and replace filter components, is convenient to assemble, can reduce component damage, and ensure the normal operation of the exhaust function.

[0004] To address the aforementioned technical problems, this application employs the following technical solution: an exhaust system for a cashmere fabric production line, comprising an inner frame, an outer frame located outside the inner frame, a support rod located within the inner frame, and an exhaust fan located at the center of the inner side of the support rod. The inner frame is equipped with a motor that drives the exhaust fan, and the exhaust fan has a rotating wheel. The rotor of the motor is connected to the rotating wheel via a belt. The outer frame is equipped with a protective cover, which has several intersecting horizontal and vertical wires forming a mesh-like filter. The entire exhaust system has a simple structure. The filter on the protective cover effectively blocks and filters lint from the air. The lint adheres to the horizontal and vertical wires, making cleaning easy; generally, only wiping the filter is required. For more detailed cleaning, the protective cover can be removed and rinsed with water. Disassembly is convenient, and assembly is also very easy after cleaning.

[0005] Preferably, the support rod is provided with at least one connector for connecting the protective cover, which is connected to a horizontal or vertical wire. This increases the reliability of the connection between the protective cover and the support rod, preventing the filter screen on the protective cover from shaking and affecting the filtration effect.

[0006] Preferably, the inner frame is equipped with louvers located behind the exhaust fan. These louvers are used to control the direction of the exhaust air and prevent air backflow caused by opposing outdoor wind directions.

[0007] Preferably, the inner frame is provided with a baffle plate, the baffle plate has a circular groove in the center, the exhaust fan is located in the circular groove, the baffle plate has a trapezoidal groove, and the motor is located in the trapezoidal groove. This prevents small amounts of lint leaking from the filter from entering the motor and exhaust fan and affecting their operation.

[0008] Preferably, the exhaust fan includes a transition plate connected to the center of the support rod, six connecting plates evenly arranged around the transition plate, and blades disposed on the connecting plates. The rotor has a hollow structure, and the connecting plates are connected to the outer ring of the rotor. The structure is simple and easy to manufacture.

[0009] Preferably, the adapter plate has a central pivot that connects to the support rod, and the adapter plate is rotatably mounted on the pivot. This ensures the normal rotation of the adapter plate and facilitates disassembly and maintenance.

[0010] Preferably, the outer wall of the pulley is provided with a groove for transmission with a belt. The belt connects the motor rotor and the groove on the outer wall of the pulley to achieve transmission, and the groove limits the position of the belt to prevent the belt from slipping off the pulley.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] The exhaust device for cashmere fabric production line provided by the above technical solution has a simple structure, which facilitates the disassembly and replacement of filter components by setting a protective cover on the outside of the exhaust fan and installing a filter screen on the protective cover. It is also convenient to assemble, which can reduce component damage and ensure the normal operation of the exhaust function. Attached Figure Description

[0020] like Figures 1 to 4 As shown, the ventilation device for a cashmere fabric production line includes an inner frame 1, an outer frame 2 located outside the inner frame 1, a support rod 3 located inside the inner frame 1, and an exhaust fan 4 located in the center of the inner side of the support rod 3. The inner frame 1 is equipped with a motor 5 that drives the exhaust fan 4 to rotate. The exhaust fan 4 is equipped with a rotating wheel 41. The rotor of the motor 5 is connected to the rotating wheel 41 by a belt 9. The outer frame 2 is equipped with a protective cover 6. The protective cover 6 is equipped with several intersecting horizontal wires 61 and vertical wires 62. The intersecting horizontal wires 61 and vertical wires 62 form a mesh filter.

[0021] The protective cover 6 is equipped with a filter screen formed by the intersection of horizontal iron wires 61 and vertical iron wires 62, which can block and filter lint in the air. The lint is adsorbed on the horizontal iron wires 61 and vertical iron wires 62, making it easy to clean. Generally, you only need to wipe the filter screen. When fine cleaning is required, the protective cover 6 can be removed and rinsed with clean water. The structure is simple, disassembly is convenient, and it can be reassembled after cleaning. Assembly is also very convenient.

[0022] The support rod 3 is equipped with at least one connector 7 for connecting to the protective cover 6. The connector 7 is connected to the horizontal wire 61 or the vertical wire 62. This increases the reliability of the connection between the protective cover 6 and the support rod 3 and prevents the filter screen on the protective cover 6 from shaking and affecting the filtration effect. A louver 8 is provided inside the inner frame 1, located behind the exhaust fan 4. This is used to control the direction of exhaust airflow and prevent air backflow caused by opposing outdoor wind directions.

[0023] The inner frame 1 is provided with a baffle 10, and the baffle 10 has a circular groove 101 in the center. The exhaust fan 4 is located in the circular groove 101. The baffle 10 has a trapezoidal groove 102, and the motor 5 is located in the trapezoidal groove 102. This is to prevent a small amount of lint leaking from the filter screen from entering the motor 5 and the exhaust fan 4 and thus affecting their operation.

[0024] The exhaust fan 4 includes a connecting plate 42 pivotally mounted on the center of the support rod 3, six connecting plates 45 evenly arranged around the connecting plate 42, and blades 43 mounted on the connecting plates 45. The rotating wheel 41 has a hollow structure, and the connecting plates 45 are connected to the outer ring of the rotating wheel 41. A rotating shaft 46, connected to the support rod 3, is located at the center of the connecting plate 42, and the connecting plate 42 is pivotally mounted on the rotating shaft 46.
