Description

Technical Field

[0001] This utility model relates to the field of dust collection devices, and in particular to a dust collection device for the lower part of an air-jet loom. Background Technology

[0002] As an important piece of equipment in the textile industry, the working efficiency and working environment of air-jet looms have a significant impact on product quality and the health of operators. However, air-jet looms generate a large amount of cotton dust and debris during production. If not handled in a timely manner, this will not only affect the normal operation of the loom but also harm the health of the operators. Therefore, the research and application of dust collection devices at the bottom of air-jet looms are of particular importance.

[0003] The existing dust collection device at the bottom of the air-jet loom mainly consists of a dust collection shell, a dust collection pipe, and a dust collection box. It is usually installed at the bottom of the air-jet loom to collect and contain cotton dust and debris generated at the bottom of the loom, and guides the cotton dust gas to the dust collection box through pipes.

[0004] On the one hand, existing dust collection devices at the bottom of air-jet looms typically have a fixed suction port, requiring sufficient suction to prevent cotton dust from falling to other places. Furthermore, the suction port cannot be adjusted to fit snugly against the bottom of the air-jet loom. On the other hand, existing dust collection devices at the bottom of air-jet looms usually use a single box to collect cotton dust. When the dust collection box is opened for cleaning, the cotton dust is affected by the airflow and flies around, making it impossible to keep the cotton dust moist and accumulating it. Therefore, a new dust collection device for the bottom of air-jet looms is proposed to solve these problems. Utility Model Content

Then, excess water is drained into the seepage tank through the drainage hole at the bottom of the slope of the dust collection box, keeping the dust collection box moist. This prevents the cotton dust from flying around due to air pollution when it is emptied. Attached Figure Description

An air duct 4 is fixedly connected to the outer end of the slider 3. The air duct 4 is U-shaped and is used to change its height through a limiting component to drive the height of the dust suction port 5. One end of the air duct 4 is fixedly connected to the dust suction port 5, which is used to connect to the bottom of the air-jet loom. The dust is drawn by a fan 6 through the dust suction port 5 into the housing 1. The other end of the air duct 4 is fixedly connected to the fan 6.

A pad 7 is fixedly connected to the outer wall of the air duct 4. The pad 7 is used to extend the air duct 4 to fit the housing 1 and keep the air duct 4 moving up and down stably.

[0033] Reference Figures 2-4A fixed rod 8 is fixedly connected to the top of the outer wall of the pad 7. The fixed rod 8 provides a hinge point for the connecting rod 9, so that when the connecting rod 9 unfolds, it can drive the fixed rod 8 to rise, achieving a lifting effect. A connecting rod 9 is hinged to the bottom of the outer wall of the fixed rod 8. The connecting rod 9 is used to change the position of its bottom end through the limiting component. A sliding rod 10 is fixedly connected to the bottom of the outer wall of the connecting rod 9. The sliding rod 10 is used to connect the two sets of connecting rods 9 to move along the connecting block 11. The outer wall of the sliding rod 10 is slidably connected to the connecting block 11. The connecting block 11 is used to drive the two sets of connecting rods 9 to make a fan-shaped unfolding movement along the hinge point of the fixed rod 8 through the limiting component. An auxiliary block 12 is fixedly connected to the bottom of the outer wall of the connecting block 11. The auxiliary block 12 is set in T shape and is used to lock the auxiliary groove 13 to keep the connecting block 11 moving stably. An auxiliary groove 1 is opened on the top of the outer wall of the box 1. 3. The auxiliary groove 13 is used to engage the auxiliary block 12 to keep the auxiliary block 12 moving stably. The outer wall end of the connecting block 11 is fixedly connected to the limiting plate 16. The limiting plate 16 is provided with a handle on the outside, which is convenient for manual pulling to move it back and forth and to extend the connecting block 11.

[0034] Reference Figures 3-4A dust cover 15 is elastically connected to the top of the outer wall of the housing 1 via a return spring 14. The dust cover 15 can be made of rubber to provide dust protection at the point where the air duct 4 passes through the housing 1, preventing gaps from allowing cotton dust to fly out. A water storage tank 18 is fixedly connected to the top of the inner wall of the housing 1, with a water inlet at the top of the tank 1 for storing water for dust suppression. A spray pipe 19 is fixedly connected to the top of the outer wall of the water storage tank 18 for spraying water to suppress the sucked-in cotton dust, preventing it from adhering to the inside of the housing 1. A seepage tank 20 is slidably connected to the bottom of the inner wall of the housing 1. The inner wall of the seepage tank 20 has a slope to guide the water to the end of the drain valve 22. A stabilizing block 21 is fixedly connected to the inner wall of the seepage tank 20. The fixed block 21 is used to maintain a certain space between the bottom of the inner wall of the dust collection box 23 and the seepage box 20 to prevent excessive water accumulation and the inner wall of the dust collection box 23 from being filled with water. A drain valve 22 is provided at the bottom of the outer wall of the seepage box 20. The drain valve 22 is used to manually drain excess water from the outside. The dust collection box 23 is placed on the top of the outer wall of the stabilizing block 21. The dust collection box 23 is provided with a slope inside.

The outer wall of the dust collection box 23 is slidably connected to the inner wall of the seepage box 20.

[0035] Reference Figures 3-5 The limiting component includes a limiting rod 24, which is used to keep the limiting block 26 moving stably up and down and to prevent the limiting block 26 from tilting due to force. The outer wall of the limiting rod 24 is elastically connected to the top inner wall of the box 1 through a limiting spring 25. The top of the outer wall of the limiting rod 24 is fixedly connected to the limiting block 26, which is used to lock the limiting groove 17 to fix the height of the dust suction port 5. One end of the limiting spring 25 is fixedly connected to the top inner wall of the box 1, and the other end of the limiting spring 25 is fixedly connected to the bottom end of the outer wall of the limiting rod 24. Through the opposing pressing force between the limiting spring 25 and the box 1, the limiting block 26 is always locked on the inner wall of the limiting groove 17 without being affected by external force. The outer wall of the limiting rod 24 is slidably connected to the top inner wall of the box 1 and the inner wall of the limiting plate 16. The outer wall of the limiting block 26 is locked on the inner wall of the limiting groove 17.

[0036] Working principle: When collecting dust at the bottom of the air-jet loom at different heights, the limiting block 26 is manually pulled out of the limiting groove 17 to release the limit. Then, the limiting plate 16 is moved back and forth, which drives the connecting block 11 to move back and forth. The connecting block 11 drives the connecting rod 9 to make a fan-shaped unfolding motion along the hinge point of the fixed rod 8. Then, the connecting rod 9 drives the fixed rod 8 to rise. The fixed rod 8 drives the air duct 4 to rise. Then, the air duct 4 drives the dust suction port 5 to rise, realizing manual adjustment of the height of the dust suction port 5 and improving the applicability of the device.

[0037] To prevent cotton dust from flying around inside the chamber 1, turn on the water pump and spray water into the chamber 1 through the spray pipe 19, so that the cotton dust adheres to the water inside the dust collection box 23. Then, drain the excess water into the seepage box 20 through the drain hole at the bottom of the slope of the dust collection box 23. Then, manually open the drain valve 22 to drain the water inside the seepage box 20. Then, lift the dust collection box 23 upwards and slide it out of the seepage box 20 to keep the dust collection box 23 moist, so as to prevent the cotton dust from flying around when emptying the dust, which would cause air pollution.
