Description

Technical Field

[0001] The invention relates to the technical field of dust removal for air jet looms, in particular to a weft yarn dust removal mechanism for air jet looms. Background Art

[0002] Air jet loom is a shuttleless loom that uses jet airflow to pull the weft yarn through the shed. The working principle is to use air as the weft insertion medium, and use the ejected compressed airflow to generate friction traction on the weft yarn to pull the weft yarn, bring the weft yarn through the shed, and achieve the purpose of weft insertion through the jet generated by the air jet. This weft insertion method can enable the loom to achieve high speed and high yield. Among several shuttleless looms, the air jet loom is the one with the highest speed. Due to the reasonable weft insertion method, high weft insertion rate, simple and safe operation, but during the use of the air jet loom, a large amount of floating dust, cotton and other impurities are often generated. These dust impurities attached to the weft yarn will not only be embedded in the fabric during the weaving process, resulting in defects, spots or uneven appearance on the fabric surface, but also the dust impurities will increase the wear of the internal components of the air jet loom such as the nozzle and the yarn guide as the weft yarn enters, shortening the service life of the equipment.

[0003] The existing Chinese patent document with publication number CN215539512U proposes to solve the above problem by setting a dust removal box and a height-adjustable support frame to perform dust removal. However, the weft yarn moves very fast with the cooperation of the airflow and the dust it carries is not easy to be removed under the action of the airflow. Dust impurities entering with the weft yarn will increase the wear of internal components of the air jet loom such as the nozzle and the yarn guide.

[0004] Therefore, the present invention proposes a weft yarn dust removal mechanism for an air jet loom, which solves the problem in the prior art that it is not easy to remove dust carried by the weft yarn by setting a dust removal box in conjunction with a height-adjustable support frame. A dust removal component is set in the weft yarn unwinder of the air jet loom before the weft yarn enters the main nozzle, and the dust and impurities on the surface of the weft yarn are separated, filtered and intercepted by utilizing the air flow pressure difference, thereby achieving the purpose of dust removal for the weft yarn.

The weft insertion center guide ring 313 guides the weft, so that the weft passes through the inside of the spindle-shaped wind cover 34 for dust removal, and finally is discharged into the main nozzle through the middle of the closed cone cover 41, which can effectively To solve the problem that it is not easy to remove dust carried by the weft yarn by setting a dust removal box in the prior art in combination with a height-adjustable support frame, the fixed weft insertion ring 31, the air inlet turbine blades 35, the spindle-shaped wind hood 34 and the conical wind hood 33 are matched to remove dust when the weft yarn passes through. The specific dust removal principle is that the motor 32 can drive the gear 321 to rotate, and the outer gear ring 351 is meshed with the gear 321 to drive the air inlet turbine blades 35 to rotate rapidly, so that the outside air is sucked into the conical wind hood 33 and the spindle-shaped wind hood 34 through the air inlet slot 312, and the wind hood sealing ring 314 is on the conical wind hood 3 The conical hood 33 is conical, with a large opening at one end and a small opening at the other end. The conical hood 33 is a special set structure with streamlined ends at the middle drum of the spindle-shaped hood 34, so that the air is divided into two parts. Most of the air flows through the conical hood 33 and the spindle-shaped hood 34, and because the opening of the conical hood 33 gradually becomes smaller, the flow rate of the air flow becomes faster to form an outer high-speed air flow, while another small part of the air flow directly enters the spindle-shaped hood 34. Because the inner diameter of the middle part of the spindle-shaped hood 34 is enlarged, the flow rate of the air flow becomes smaller, and a low-speed air flow is formed on the outer surface of the weft yarn. The dust removal auxiliary ring 36 rotates to contact and move the weft yarn so that the dust adhering to the weft yarn is taken away by the low-speed airflow. According to the Bernoulli principle, the pressure in the area with higher flow velocity is lower, while the pressure in the area with lower flow velocity is higher. When the flow velocity of the outer airflow is greater than that of the inner airflow, the pressure on the outer side will be lower than that on the inner side. In this way, the dust carried by the inner low-speed airflow will be pushed to the outer side with lower pressure through the dust removal groove 341 and taken out by the high-speed airflow, so as to achieve the purpose of separating the dust from the weft yarn. Finally, the dust is intercepted by the dust interception cover 42 to achieve the purpose of dust removal on the weft yarn. It is very simple to use and has a good dust removal effect. ;

[0038] Embodiment 2, on the basis of embodiment 1, in order to make the dust adhered to the surface of the weft yarn be fully shaken off when the weft yarn passes through the spindle-shaped wind hood 34, so that the dust can be carried away by the airflow and separated from the weft yarn, an auxiliary dust removal ring 36 is fixedly installed on the surface of one side of the air inlet turbine blade 35 close to the spindle-shaped wind hood 34, and the auxiliary dust removal ring 36 is arranged inside the spindle-shaped wind hood 34, and a dust removal lever 361 is hingedly installed on the inner side of the auxiliary dust removal ring 36 through a support rod, and a limiting baffle 363 is provided on one side of the dust removal lever 361, and a buffer support rod 362 is fixedly installed on the outer surface of the limiting baffle 363, and one end of the buffer support rod 362 is fixedly connected to the outer surface of the support rod of the auxiliary dust removal ring 36; in this embodiment, the reinforcement ring 331 plays the role of stabilizing and fixing the conical wind hood 33 and the spindle-shaped wind hood 34, so that the small end of the conical wind hood 33 is close to the spindle The part with the largest diameter in the middle of the spindle-shaped wind hood 34 is sleeved to form a narrow air outlet duct, so that most of the air passing through the spindle-shaped wind hood 34 and the conical wind hood 33 forms a high airflow, and the air inlet turbine blades 35 rotate rapidly under the cooperative drive of the motor 32 and the gear 321. At this time, the auxiliary dust removal ring 36 and the air inlet turbine blades 35 are fixed and rotate synchronously. Under the cooperative action of centrifugal force and gravity, the dust removal lever 361 generates a swinging effect to contact the surface of the weft yarn and produce a stirring effect on the weft yarn when the auxiliary dust removal ring 36 rotates, so that the dust carried by the weft yarn is fully shaken off and carried away by the low-speed airflow passing through the inside of the spindle-shaped wind hood 34. The buffer support rod 362 mainly cooperates with the limit baffle 363 to provide stable support for the surface of the weft yarn, and buffers the weft yarn vibration caused by the dust removal lever 361, so that the weft yarn routing is more stable.

[0039] Embodiment 3, on the basis of embodiment 2, a closed conical cover 41 is arranged on the inner side of the fixed weft insertion ring 31, an exhaust cover 411 is fixedly mounted on one end of the closed conical cover 41, and an oblique air outlet slot is opened on the side wall of the exhaust cover 411. A weft yarn stabilizer 412 is fixedly installed at one end of the exhaust hood 411, and a dust interception hood 42 is snap-fitted on the inner surface of the closed conical hood 41. The size of the dust interception hood 42 is adapted to the size of the closed conical hood 41 and the exhaust hood 411. The inner surface of one side of the spindle-shaped wind hood 34 on which the dust removal groove 341 is opened is snap-fitted with the side surface of the dust interception hood 42. The inner surface of the dust interception hood 42 is evenly distributed with guide strips 421, and stabilizing rings 422 are fixedly installed between the guide strips 421. Ash storage folding nets 423 are fixedly installed between the stabilizing rings 422, and the ash storage folding nets 423 are staggered with the guide strips 421. In this embodiment, the closed conical hood 41 can be detachably installed on one side of the fixed weft insertion ring 31 by using threads or bolts, and the closed conical hood 41 plays the role of closing the spindle-shaped wind hood 34. , and the conical wind hood 33. At the same time, the dust interception hood 42 can be installed through the card hole, which is convenient for the dust interception hood 42 to be disassembled and cleaned. The shape of the dust interception hood 42 is completely in line with the closed conical hood 41 and the exhaust hood 411, and can effectively intercept the dust carried by the outer airflow, so as to achieve the purpose of separating the airflow and dust, so that the dust is adsorbed on the inner side of the dust interception hood 42. The guide strip 421 can play a guiding role, so that the dust collides and flows along the guide strip 421 into the gap between the dust interception hood 42 and the conical wind hood 33. The stabilizing ring 422 cooperates with the ash storage folding net 423 to increase the adhesion area of ​​the dust, so that the dust is intercepted and temporarily stored during the collision. Later, you only need to disassemble the closed conical hood 41 to separate the dust interception hood 42, so that the dust can be cleaned centrally.

[0040] Embodiment 4, on the basis of embodiment 3, a weft stabilizer 412 is fixedly installed at one end of the exhaust hood 411; in this embodiment, the exhaust hood 411 at the front end of the closed conical hood 41 is also conical, but its direction is opposite to that of the closed conical hood 41. This design can make the airflow generated by the spindle-shaped hood 34 and the conical hood 33 have a guiding effect when it is discharged, and cooperate with the oblique air outlet slot to extend the flow length of the discharged airflow, so that the airflow can be discharged in close contact with the surface of the weft yarn, so that before the weft yarn enters the main nozzle, due to the interference of the airflow To prevent dust in the air from adhering to the surface of the weft yarn again, the weft yarn stabilizer 412 extends to the inner side of the dust removal groove 341, and one end of the weft yarn stabilizer 412 gradually becomes smaller. An arc-shaped gasket ring is also provided at its front end. Because larger dust particles may stay in the inner low-speed airflow for a longer time, the weft yarn stabilizer 412 can finally intercept the dust remaining in the inner low-speed airflow, so that it can be dispersed through the guidance of the arc-shaped gasket ring and pushed back to the outside under the action of the pressure difference between the inside and the outside, and can be successfully intercepted by the dust interception cover 42, thereby improving the dust removal effect of the weft yarn.

[0041] Embodiment 5. On the basis of embodiment 4, this embodiment further proposes a dust removal method for a weft dust removal mechanism for a jet loom, comprising the following steps: step 1, installing and fixing the weft insertion ring 31, fixing the fixing bracket 311 on the dust removal component fixing bracket 21 with bolts, manually combing the weft yarn to be unwound from the weft yarn unwinder 2 and enter the weft insertion center guide ring 313 in the middle of the fixed weft insertion ring 31, pass through the inside of the spindle-shaped wind hood 34, and finally be discharged into the main nozzle through the middle of the exhaust hood 411; step 2, starting the jet loom, the jet loom weft storage unwinding device 1 of the jet loom cooperates with the weft yarn unwinder 2 to unwind the weft yarn, and at the same time, the motor 32 works to drive the air inlet turbine blades 35 to rotate rapidly, and the outside air is sucked into the conical wind hood 33 and the spindle-shaped wind hood through the air inlet slot 312. Inside the hood 34, most of the airflow passes through the conical wind hood 33 and the spindle-shaped wind hood 34 to form an outer high-speed airflow, while another small part of the airflow directly enters the spindle-shaped wind hood 34 to form a low-speed airflow on the outer surface of the weft yarn. The auxiliary dust removal ring 36 rotates to contact and move the weft yarn so that the dust sticking to the weft yarn is carried away by the low-speed airflow, and the dust carried by the inner low-speed airflow will be pushed to the outer side with lower pressure through the dust removal groove 341 and carried out by the high-speed airflow; Step three, the shape of the dust interception hood 42 is completely fitted with the closed conical hood 41 and the exhaust hood 411, which can effectively intercept the dust carried by the outer airflow and make it adsorbed on the inner side of the dust interception hood 42. Subsequently, you only need to disassemble the closed conical hood 41 and separate the dust interception hood 42 to clean the dust centrally.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
