Description

Technical Field

[0001] The present invention relates to the field of dust collection for air-jet looms, and specifically to a lower dust collection device for air-jet looms. Background Art

[0002] An air-jet loom uses air as the weft insertion medium, and the ejected compressed air flow generates frictional traction on the weft yarn to tow it, and the weft yarn is brought across the shed to achieve the purpose of weft insertion. During the high-speed operation, the air-jet loom will generate a large amount of cotton dust and fiber flocs. If these cotton dust and fiber flocs are not cleaned in time, they will not only pollute the working environment, affect the normal operation of the loom, but also may have an adverse effect on the quality of the fabric. Therefore, setting a dust collection device at the lower part of the air-jet loom can effectively collect these cotton dust and fiber flocs, keep the working environment clean, and ensure the stable operation of the loom and the quality of the fabric.

[0003] In the prior art, due to the large amount of fine cotton dust generated during the high-speed operation of the air-jet loom being difficult to be effectively captured by traditional dust collection methods, and the cotton dust having the characteristics of being easy to fly and spread, it leads to the cotton dust being easy to escape from the dust collection device during the dust collection process, further reducing the dust collection effect, making the collection and subsequent treatment of cotton dust difficult.

[0017] In order to clearly and completely describe the purpose, technical solution of the present invention and make the advantages more clearly understood, the following further details the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0018] Embodiment 1, please refer to Figure 1 - Figure 13, the present invention provides a technical solution: a lower dust collection device for a jet loom, including a converging shell 1, the converging shell 1 is arranged at the bottom end of the jet loom, the bottom end of the converging shell 1 is fixedly communicated with a guiding pipe 3, a dust collection mechanism is arranged at the bottom end of the guiding pipe 3, the dust collection mechanism includes a rectangular box 6, a driving mechanism and a meandering belt 2, the rectangular box 6 is fixedly communicated at the bottom end of the guiding pipe 3, the bottom end of the rectangular box 6 is fixedly communicated with a separation box 41, a collection component is arranged at the bottom end of the separation box 41, a plurality of through grooves arranged at equal intervals are formed at one end of the meandering belt 2, and auxiliary components are arranged inside each through groove, the auxiliary components include a spiral member 17, a water inlet cylinder 22, a special collar 23 and a water outlet cylinder 28, the water inlet cylinder 22 and the special collar 23 are respectively fixedly connected to both ends of the spiral member 17, and one end of the special collar 23 is fixedly communicated with the water outlet cylinder 28. By setting the driving mechanism, the meandering belt 2 will perform intermittent transmission, and each auxiliary component arranged inside it will rotate synchronously under the influence of the air flow, and collect the cotton dust generated during the operation of the jet loom. The spiral-shaped spiral member 17 will absorb more cotton dust, thereby improving the dust collection efficiency. These cotton dust will then be wetted and collected again, further enhancing the dust collection effect.

[0019] In Embodiment 2, on the basis of Embodiment 1, both ends of the through groove respectively penetrate through both sides of the meandering belt 2, the water inlet cylinder 22 and the water outlet cylinder 28 are both rotatably connected inside the through groove, annular strips are fixedly connected to the outer walls of the water inlet cylinder 22 and the water outlet cylinder 28, and the annular strips are rotatably connected inside the through groove. The cross section of the spiral member 17 is in a spiral shape, a plurality of receiving openings 21 arranged at equal intervals are formed on the outer wall of the spiral member 17, a plurality of check members 18 arranged at equal intervals are hinged on the inner wall of the spiral member 17, a bent elastic member 19 is fixedly connected between one end of the check member 18 and the inner wall of the spiral member 17, a collection cavity 20 is fixedly connected to the innermost inner wall of the spiral member 17, the collection cavity 20 is integrally through, and a plurality of air receiving blocks 43 arranged at equal intervals are fixedly connected to the outer wall of the spiral member 17 farthest from the axis, and one end of the air receiving block 43 is hollow.

[0020] By setting the annular strips, the stability of the rotation of the water inlet cylinder 22 and the water outlet cylinder 28 is improved. Refer to the attached Figure 4 and 6 , the direction of the air flow with cotton dust being inhaled is: from the upper right to the lower left. By setting the respective air receiving blocks 43, the air flow will blow into the inside of each air receiving block 43 in sequence. Under the push of the air flow, the spiral member 17 rotates around its axis. Refer to the attached Figure 6Taking this as an example, it rotates clockwise. The cotton dust in the airflow will then gradually enter the deepest part of the spiral member 17 along the opening at one end of the spiral member 17. The distance from the axis of the spiral member 17 gradually decreases, and finally it is concentrated in the inner cavity of the collection chamber 20 to complete the first collection. A number of storage openings 21 provide a temporary storage space for the cotton dust again, further improving the dust collection ability of the winding belt 2. During the above process, the cotton dust in the airflow will act on each check member 18. The multiple check members 18 respectively flip towards the direction close to the spiral member 17 along their hinge points, and finally squeeze the elastic member 19. By providing the check member 18 and the elastic member 19, it prevents the cotton dust from deviating from the specified path, which is beneficial for collection.

[0021] Embodiment 3: On the basis of Embodiment 2, one end of the special collar 23 is provided with a first strengthening groove 24 and multiple groups of advanced grooves. The first strengthening groove 24 is located at the axis of the special collar 23. The multiple groups of advanced grooves are arranged at equal intervals around the axis of the special collar 23. Each group of advanced grooves includes three non-connecting internal second strengthening grooves 25. The second strengthening groove 25 is composed of two relatively positioned triangular prisms. The bottom area of the triangular prism closer to the water outlet cylinder 28 is larger than the bottom area of the triangular prism farther from the water outlet cylinder 28. The first strengthening groove 24 is composed of two relatively positioned frustum-shaped grooves with equal top areas. The bottom area of the frustum closer to the water outlet cylinder 28 is larger than the bottom area of the frustum farther from the water outlet cylinder 28. The first strengthening groove 24 and the collection chamber 20 are on the same horizontal line. A connecting plate 4 and a baffle 5 are fixedly connected between the two inner walls of the rectangular box 6. The baffle 5 is fixedly connected to one end of the connecting plate 4. The top end of the connecting plate 4 is fixedly connected to the guide pipe 3. The driving mechanism includes a first motor 7. The first motor 7 is fixedly connected to the top of the rectangular box 6. One end of the output shaft of the first motor 7 passes through the top of the rectangular box 6 and is fixedly connected to a first helical gear 8. The outer wall of the first helical gear 8 is engaged with a second helical gear. One end of the second helical gear is fixedly connected to a suction fan blade 9. A fastening plate 10 is fixedly connected between the top end of the baffle 5 and the top inner wall of the rectangular box 6. A filter grid 11 is fixedly connected between the connecting plate 4 and the top inner wall of the rectangular box 6. A part of the suction fan blade 9 is located between the fastening plate 10 and the filter grid 11. The shaft rod of the suction fan blade 9 is rotationally connected to the fastening plate 10. One end of the outer wall of the rectangular box 6 is provided with a second motor 14. One end of the output shaft of the second motor 14 passes through one side inner wall of the rectangular box 6 and is fixedly connected to a cutting gear 16. The outer wall of the cutting gear 16 is engaged with an incomplete gear 15. One end of the incomplete gear 15 is fixedly connected to one end of an inner shaft cylinder 13 rotatably connected in the inner cavity of the rectangular box 6. A plurality of outer shaft cylinders 12 and inner shaft cylinders 13 are rotatably connected between the two inner walls of the rectangular box 6. A plurality of outer shaft cylinders 12 are all in transmission connection with the outer wall of the winding belt 2. A plurality of inner shaft cylinders 13 are all in transmission connection with the inner wall of the winding belt 2. One of the inner shaft cylinders 13 is rotatably connected between the two inner walls of the separation box 41.

[0022] Since the converging shell 1 is arranged at the bottom end of the air-jet loom, and a guiding pipe 3 is fixedly connected to the bottom end of the converging shell 1, the cotton dust generated at the lower end of the air-jet loom will fall into the converging shell 1. Because the guiding pipe 3 is inclined as a whole, the cotton dust will then enter the inside of the guiding pipe 3. Through the arranged connecting plate 4, baffle 5, motor 1 7, helical gear 1 8 and suction fan blades 9, as shown in the attached Figure 3 of the specification. When the motor 1 7 is started, the helical gear 1 8 will rotate synchronously. Under the connection of the helical gear 2 meshing with it, the suction fan blades 9 rotate to generate suction, so as to suck the cotton dust inside the guiding pipe 3 towards the direction of the suction fan blades 9. Blocked by the winding belt 2, the traveling route of these cotton dust is blocked. It should be noted here that: the motor 2 14 will be started synchronously when the air-jet loom is working; the arc length of the gear part of the incomplete gear 15 occupies seven twentieths of its overall arc length, and the smooth part occupies thirteen twentieths. The gear part of the cutting gear 16 has two sections, and the arc length together occupies seven tenths of its overall arc length, and the smooth part occupies three tenths. The two smooth parts on the cutting gear 16 are symmetrically distributed with the gear part. The arc length of the gear part of the incomplete gear 15 is equal to the arc shape of the two gear parts of the cutting gear 16. Through the arranged incomplete gear 15 and cutting gear 16, the attached Figure 9 of the specification is the initial state when the motor 2 14 is not started. When the incomplete gear 15 rotates with the motor 2 14, the smooth part of the incomplete gear 15 first slides along one of the smooth parts of the cutting gear 16, and the cutting gear 16 does not rotate. Then the gear part of the incomplete gear 15 will push one end of the smooth part of the cutting gear 16 and immediately mesh with the gear part of the cutting gear 16, and the cutting gear 16 rotates synchronously. When the gear part of the incomplete gear 15 disengages from the cutting gear 16, the smooth part of the incomplete gear 15 just has a sliding connection relationship with the other smooth part of the cutting gear 16. At this time, when the incomplete gear 15 rotates again, the cutting gear 16 does not rotate. Generally speaking, the incomplete gear 15 will continue to rotate, and the cutting gear 16 will rotate intermittently. The inner shaft cylinder 13 arranged in the separation box 41 also rotates synchronously corresponding to the attached Figure 9Reference numeral 13 therein causes the meandering belt 2 to be driven under the combined drive of the remaining inner shaft cylinder 13 and each outer shaft cylinder 12. The meandering belt 2 in the running state will first block the cotton dust going to the suction fan blade 9. The spiral members 17 hidden inside each through groove are rotated by the influence of the air flow to collect the cotton dust for the first time. The intermittent operation mode increases the residence time of the spiral members 17 inside 49 instead of passing by in a flash, enabling the spiral members 17 to collect more cotton dust, thereby enhancing the dust collection effect. The filter grid 11 is provided to secondarily block the remaining cotton dust, greatly reducing the influence on the rotation of the suction fan blade 9. The fastening plate 10 supports the shaft rod of the suction fan blade 9 to ensure its normal operation. Secondly, air holes for air flow passage and exchange are provided at one end of both the fastening plate 10 and the rectangular box 6.

[0023] Embodiment 4, on the basis of Embodiment 3, a protective shell 31 is fixedly connected to the outer wall of one side of the separation box 41. A water delivery system 42 is arranged inside the protective shell 31. Through the arranged water delivery system 42, water can enter the inside of the separation box 41.

[0024] It should be noted here that: The water delivery system includes devices such as water pumps and water pipes. These are all existing mature technologies. Applied here, they are only used to input water flow. The detailed working process of the water delivery system will not be elaborated. By starting the water delivery system 42, it can introduce water flow from the outside. The high-speed water flow will directly enter the inside of the water outlet cylinder 28 closest to the water inlet position. Then these water flows pass through the special collar 23. Through the arranged first enhanced groove 24 and each group of advanced grooves, the water flows enter the inside of the first enhanced groove 24 and the advanced grooves with a certain pressure. Since the cross-sectional areas of the first enhanced groove 24 and the advanced grooves gradually decrease, the flow velocity of the fluid gradually increases. When reaching the middle position, such as the junction of the two frustums, the flow velocity reaches the maximum, and at this time the kinetic energy of the water flow also reaches the maximum. Then the water flow will spray out in a relatively strong state. Also due to the positional relationship between the special collar 23 and the spiral members 17, the water flow will directly enter the inner cavity of the collection chamber 20, the spaces of each spiral shape of the spiral members 17, and the inside of each receiving port 21 to mix the concentrated and remaining cotton fluffs with water. Finally, it leaves through the water inlet cylinder 22 together with the water flow and enters the inside of the separation box 41 and the triangular box 26. The washed spiral members 17 are prepared for the next cotton dust collection.

[0025] Embodiment 5, on the basis of embodiment 4, the collecting component comprises a triangular box 26, the bottom end of the triangular box 26 is fixedly connected to a trapezoidal box 29, the cross section of the triangular box 26 is a right triangle, a third motor is arranged on one side outer wall of the triangular box 26, one end of the output shaft of the third motor is fixedly connected to a horizontal shaft rod, the horizontal shaft rod is rotatably connected between the inner walls of both sides of the triangular box 26, a bottom plate 27 is fixedly connected to the outer wall of the horizontal shaft rod, the bottom plate 27 can completely close the bottom end opening of the triangular box 26, and a sliding plate is provided on the top of the trapezoidal box 29. Slot 1 32, a motor 4 36 is provided on the top of the trapezoidal box 29, and three fixed blocks 33 are fixedly connected to the top of the trapezoidal box 29, wherein the positions of two fixed blocks 33 are far away from each other and a threaded rod 44 is rotatably connected between the two, one end of the threaded rod 44 is fixedly connected to a short rod, one end of the short rod passes through the side of one of the two fixed blocks 33, one end of the output shaft of the motor 4 36 passes through the outer wall of one side of the remaining fixed block 33, and a connecting belt 35 is transmission-connected between the outer wall of the output shaft of the motor 4 36 and the outer wall of the short rod, the trapezoidal box 29 is fixedly connected to the top of the trapezoidal box 29, and the two fixed blocks 33 are located far away from each other. A threaded rod 44 is rotationally connected between the two fixed blocks 33, and a short rod is fixedly connected to one end of the threaded rod 44, and one end of the short rod passes through the side of one of the two fixed blocks 33. One end of the outer wall of the box 29 is fixedly connected and connected with a drain port 30, the outer wall of the threaded rod 44 is threadedly connected with a connecting plate 34, the bottom end of the connecting plate 34 is fixedly connected with an extrusion block 37, the cross section of the extrusion block 37 is a right-angled trapezoid, and a filter plate 38 is fixedly connected between the inner walls of the two sides of the trapezoidal box 29, the bottom end of the extrusion block 37 is slidably connected to the top of the filter plate 38, and the bottom end of the filter plate 38 is fixedly connected with two reinforcement members 39 at positions far away from each other, one end of the reinforcement member 39 is fixedly connected to one side of the inner wall of the trapezoidal box 29, and the trapezoidal box A collecting box 45 is fixedly connected to the outer wall of one side of the collecting box 29, a transverse groove 1 40 is provided on the side of the trapezoidal box 29 close to the collecting box 45, a transverse groove 2 is provided on the side of the closing door 47 close to the trapezoidal box 29, both the transverse groove 1 40 and the transverse groove 2 are through-type, a closing door 47 is hingedly connected to the outer wall of one side of the collecting box 45, a compression assembly 46 is arranged on the top of the collecting box 45, the compression assembly 46 includes a driving rod and an extrusion plate, the bottom end of the driving rod passes through the top of the collecting box 45 and is fixedly connected to the extrusion plate, and the extrusion plate is slidably connected to the inside of the collecting box 45.

[0026] One outer wall of the collection box 45 is provided with a drainage channel. As the water volume increases and with the intermittent movement of the meandering belt 2, the amount of cotton dust contained in the water gradually increases. By starting the second motor, the bottom plate 27 deflects along the axis of the horizontal shaft rod, and the opening at the bottom end of the triangular box 26 is revealed. The mixture inside the separation box 41 and the triangular box 26 will then enter the interior of the trapezoidal box 29. Under the blocking and filtration of the filter plate 38, the cotton dust is left on the top of the filter plate 38. Start the fourth motor 36. Under the connection action of the connecting belt 35 and the threaded rod 44, the connecting plate 34 displaces along the threaded rod 44 and synchronously drives the extrusion block 37. During the displacement, the extrusion block 37 will push the cotton dust on the top of the filter plate 38. Through the first horizontal groove 40 opened, when the extrusion block 37 contacts the inner wall of the trapezoidal box 29, this cotton dust is also pushed into the interior of the collection box 45. Subsequently, when the amount of cotton dust inside the collection box 45 reaches a certain level, the extrusion and compression assembly 46 can be used to compress the collected cotton wool, drain the water, reduce the space, and it can be taken out from the closing door 47. Note: Observe the attached instruction manual Figure 11 The right end of the filter plate 38 is the first horizontal groove 40. By means of the provided reinforcing member 39, the contact area between the filter plate 38 and the interior of the trapezoidal box 29 is indirectly increased, the stability is increased, and it is beneficial to the pushing and collection of the cotton wool.

[0027] During actual use, the direction of the airflow with cotton dust being inhaled is: from the upper right to the lower left. The airflow will blow into the interior of each air-receiving block 43 in sequence. Driven by the airflow, the spiral member 17 rotates around its axis. Taking the accompanying drawings of the specification as an example, it rotates clockwise. The cotton dust in the airflow will then gradually enter the deepest part of the spiral member 17 along the opening at one end of the spiral member 17, and the distance from the axis of the spiral member 17 gradually decreases. Eventually, it is concentrated in the inner cavity of the collection chamber 20 to complete the first collection. A number of storage ports 21 provide a temporary storage space for the cotton dust again, further improving the dust collection capacity of the meandering belt 2. The intermittent setting increases the residence time of the spiral member 17 inside 49 instead of passing by in one go, enabling the spiral member 17 to collect more cotton dust, thereby enhancing the dust collection effect. By starting the water supply system 42, it can introduce water from the outside. The high-speed water flow will directly enter the interior of the water outlet cylinder 28 closest to the water inlet position. These water flows then pass through the special collar 23. Through the provided enhanced groove 1 and each group of advanced grooves, the water flow will spray out in a relatively strong state. The cotton fluffs in the inner cavity of the collection chamber 20, in the spaces of various spiral shapes of the spiral member 17, and inside each storage port 21 will mix with the water and finally leave through the water inlet cylinder 22 and enter the separation box 41 and the triangular box 26 together with the water flow. The washed spiral member 17 will be ready for the next cotton dust collection. The mixture inside the separation box 41 and the triangular box 26 will then enter the interior of the trapezoidal box 29. Blocked and filtered by the filter plate 38, the cotton dust is left on the top of the filter plate 38. Start the fourth motor 36, the connecting plate 34 displaces along the threaded rod 44, and synchronously drives the extrusion block 37. During the displacement process, the extrusion block 37 will push the cotton dust on the top of the filter plate 38. When the extrusion block 37 contacts the inner wall of the trapezoidal box 29, these cotton dusts are also pushed into the interior of the collection box 45. Subsequently, when the cotton dust inside the collection box 45 reaches a certain amount, the extrusion and compression assembly 46 can be used to compress the collected cotton fluffs, drain the water, reduce the space, and it can be taken out from the closing door 47, which is conducive to the pushing and collection of the cotton fluffs.
