Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, specifically to a lint removal device for air-jet looms. Background Technology

[0002] With the continuous development of science and technology, the textile industry has also made great progress. Taking looms as an example, early looms were shuttle looms driven by human power, but nowadays, shuttleless looms, represented by air-jet looms, have gradually become the mainstream.

[0003] Dust in air-jet looms is mainly composed of fiber debris. When dust adheres to the surface of the yarn, it can cause appearance defects such as "excessive fuzz" and "neps" in the fabric. When dust accumulates on the loom parts, it increases frictional resistance, leading to unstable equipment operation. Furthermore, dust can easily be inhaled by the human body, causing cotton dust disease. Summary of the Invention

[0004] This invention provides a lint removal device for air-jet looms, which can effectively remove dust from the surface of yarn, prevent dust from accumulating on loom parts and causing equipment failure, and effectively prevent cotton dust disease caused by inhaling dust.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: A lint removal device for an air-jet loom includes a frame. A cleaning roller assembly for cleaning yarn lint is provided on the frame along the weft insertion direction of the yarn. A dust collection trough is provided below the cleaning roller assembly, and a honeycomb filter is provided in the dust collection trough. The cleaning roller assembly includes at least one brush roller. Both ends of the brush roller are movably mounted on the frame via a dust shaking component. The dust shaking component automatically adjusts the contact pressure between the brush and the yarn by shaking.

[0006] Preferably, the dust-shaking assembly includes a connecting arm and a shaking cylinder for driving the connecting arm to shake up and down. The output end of the shaking cylinder is fixedly connected to the middle of the connecting arm. One end of the connecting arm is rigidly connected to the end of the hair roller shaft, and the other end of the connecting arm is movably mounted on the frame via a mounting base.

[0007] Preferably, the mounting base includes an arc-shaped groove with an elastic element, and the end of the connecting arm away from the brush roller is slidably disposed in the arc-shaped groove via a slide rod.

[0008] Preferably, the cleaning roller assembly includes two brush rollers, which are stacked one on top of the other, rotate in opposite directions, and abut against each other axially.

[0009] Preferably, the brush rollers are stacked one on top of the other to form a "Z" shaped cleaning path.

[0010] Preferably, one of the two brushes uses soft, anti-static nylon bristles, and the other uses hard silicon carbide bristles.

[0011] Preferably, the honeycomb filter element includes a stainless steel mesh, a honeycomb core disposed within the stainless steel mesh, and activated carbon filled within the honeycomb core.

[0012] Preferably, electrostatic adsorption meshes are provided both upstream and downstream of the honeycomb filter element.

[0013] Preferably, the frame is also provided with a dust cover, which is rotatably mounted on the frame by a cylinder.

[0014] Preferably, the bottom of the dust collection tank is provided with at least one jet pipe, which is connected to an air pump, and the jet pipe is provided with multiple jet ports. In summary, the advantages of this utility model are: This not only solves the direct damage to yarn quality caused by fuzz, but also achieves comprehensive benefits from multiple dimensions such as equipment maintenance, production efficiency, and environmental protection. First, the brush roller in the cleaning roller assembly is arranged along the weft insertion direction of the yarn. Through direct contact between the bristles and the yarn, harmful fuzz on the yarn can be efficiently removed. Second, the two ends of the brush roller are connected by a dust shaking component, which can automatically adjust the contact pressure between the brush and the yarn according to the yarn tension to avoid excessive friction that could damage the yarn, while ensuring the cleaning effect. Then, large fuzz particles settle to the bottom of the tank by gravity, while fine dust is captured by the honeycomb filter in the dust collection tank. The stacked brush rollers form a "Z"-shaped cleaning path. The yarn first passes through the horizontal combing of the upper brush roller to remove surface lint, and then passes through the vertical peeling of the lower brush roller to deeply remove stubborn lint embedded in the yarn, greatly improving lint removal efficiency; The honeycomb filter element adopts a multi-stage filtration method. The stainless steel mesh is used to intercept large particles of fuzz, the honeycomb core is used to capture particulate dust, and the activated carbon is used to adsorb oily volatiles, which facilitates the purification of the air in the working environment. 4. An air jet pipe and air jet nozzle are installed at the bottom of the dust collection tank. The air jet pipe is connected to an air pump. Air jets are sprayed at the bottom of the dust collection tank through the air jet nozzle, which can create a turbulent area at the bottom of the dust collection tank, effectively preventing dust from accumulating and causing blockage of the suction port.

It should be understood that the terms "upper," "lower," "left," "right," "longitudinal," "lateral," "inner," "outer," "vertical," "horizontal," "top," and "bottom," etc., indicating orientation or positional relationships, are based solely on the orientation or positional relationships shown in the accompanying drawings and are used only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device / component referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Example

[0018] A lint removal device for air-jet looms, such as Figure 1 As shown, the machine includes a frame 1, on which a cleaning roller assembly 2 for cleaning yarn fuzz is provided along the yarn weft insertion direction. A dust collection trough 3 is provided below the cleaning roller assembly 2, and a honeycomb filter is provided in the dust collection trough 3. The cleaning roller assembly 2 includes at least one brush roller 21, and the two ends of the brush roller 21 are movably mounted on the frame 1 through a dust shaking assembly 4.

[0019] This invention not only solves the problem of direct damage to yarn quality caused by fuzz, but also achieves comprehensive benefits from multiple dimensions such as equipment maintenance, production efficiency, and environmental protection. First, the brush roller in the cleaning roller assembly 2 is arranged along the weft insertion direction of the yarn. Through direct contact between the brush bristles and the yarn, harmful fuzz on the yarn can be efficiently removed. Second, the two ends of the brush roller 21 are movably connected by the dust shaking assembly 4, which can automatically adjust the contact pressure between the brush and the yarn according to the yarn tension, avoiding excessive friction that could damage the yarn, while ensuring the cleaning effect. Then, large particles of fuzz settle to the bottom of the tank by gravity, while fine dust is captured by the honeycomb filter in the dust collection tank 3.

[0020] like Figure 4As shown, the dust-shaking assembly 4 includes a connecting arm 41 and a shaking cylinder 42 that drives the connecting arm 41 to shake up and down. The output end of the shaking cylinder 42 is fixedly connected to the middle of the connecting arm 41. One end of the connecting arm 41 is rigidly connected to the shaft end of the brush roller 21, and the other end of the connecting arm 41 is movably mounted on the frame 1 via a mounting base 43. The mounting base 43 includes an arc-shaped groove, and the end of the connecting arm 41 away from the brush roller 21 is slidably mounted in the arc-shaped groove via a sliding rod. With this configuration, the output end of the shaking cylinder 42 is fixedly connected to the middle of the connecting arm 41, forming a motion mode similar to a crank-rocker mechanism. When the cylinder piston rod performs linear reciprocating motion, the connecting arm 41 generates a lever amplification effect with the mounting base 43 as the fulcrum, causing the vibration amplitude at the end of the brush roller 21 to be several times greater than the cylinder stroke, effectively improving the brush's efficiency in removing embedded dust.

[0021] Understandably, elastic elements can also be installed on the mounting base 43 to absorb vibration and impact energy, while also reducing the overall noise of the equipment.

[0022] Specifically, such as Figure 3 As shown, the cleaning roller assembly 2 includes two brush rollers 21, which are stacked one on top of the other, rotate in opposite directions, and abut against each other axially. This arrangement creates a "Z"-shaped cleaning path between the stacked rollers 21. The yarn first passes through the upper roller 21 for transverse combing, removing surface lint, and then through the lower roller 21 for longitudinal stripping, deeply removing stubborn lint embedded in the yarn, greatly improving lint removal efficiency.

[0023] Of the two stacked brush rollers 21, the upper brush roller 21 has bristles made of soft, anti-static nylon filaments to absorb loose hair and dissipate static electricity, while the lower brush roller 21 has bristles made of hard silicon carbide to tackle stubborn hair. This complementary design of upper and lower brush bristles effectively enhances the service life of the brush and further improves its cleaning efficiency.

[0024] This embodiment of the honeycomb filter includes a stainless steel mesh, a honeycomb core disposed within the stainless steel mesh, and activated carbon filled within the honeycomb core. Employing a multi-stage filtration method, the stainless steel mesh intercepts large particles of fuzz, the honeycomb core captures particulate dust, and the activated carbon adsorbs oily volatiles, facilitating the purification of air in the working environment.

[0025] To prevent dust escape, electrostatic adsorption meshes are installed both upstream and downstream of the honeycomb filter element. This arrangement allows the upstream and downstream electrostatic adsorption meshes to be designed in parallel, thereby forming a laminar flow channel. This reduces the deviation in airflow velocity within the honeycomb core, effectively preventing dust escape and further improving the filtration effect.

[0026] In this embodiment, the frame 1 is also equipped with a dust cover 8, such as Figure 2As shown, the dust cover 8 can be flipped and mounted on the frame 1 via a flipping cylinder 9. With this configuration, the dust cover 8 can be flipped by the flipping cylinder 9, completely covering key components such as the warp beam and weft insertion mechanism. When the dust cover 8 is closed, it can form a negative pressure sealed cavity, which can significantly reduce the dust escape rate.

[0027] In this embodiment, at least one air jet pipe 6 is provided at the bottom of the dust collection tank 3. The air jet pipe 6 is connected to the air pump 10, and multiple air jet ports 7 are provided on the air jet pipe 6. In practical applications, the number of air jet pipes can be reasonably set according to needs. By spraying air through the air jet ports 7 at the bottom of the dust collection tank 3, a turbulent disturbance zone can be formed at the bottom of the dust collection tank 3, which can effectively prevent dust accumulation and blockage of the suction port.

[0028] In addition to the preferred embodiments described above, there are other embodiments of this utility model. Those skilled in the art can make various changes and modifications based on this utility model. As long as they do not depart from the spirit of this utility model, they should all fall within the scope defined by the appended claims.
