Description

Technical Field

[0001] The invention relates to the technical field of air jet looms, and in particular to a lower dust collecting device and method for an air jet loom. Background Art

[0002] The 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 jetted compressed airflow to generate friction traction on the weft yarn to pull the weft yarn through the shed, and achieve the purpose of weft insertion through the jet generated by the air jet; the lower dust collection device of the air jet loom is a device used to collect dust from the lower part of the air jet loom to remove cotton dust and improve the working environment.

[0003] The dust collecting port of the existing lower dust collecting device of the jet loom is mostly exposed. When air is sucked through the dust collecting port for dust collection, some fiber lint will enter the dust collecting port when the jet loom is working and block the dust collecting port, affecting the overall dust collection effect. In addition, the fiber lint is light in texture and very easy to float away, which is inconvenient to handle. It is time-consuming and laborious to handle, which greatly reduces the practicality of the device. Summary of the invention

[0004] The present invention provides a lower dust collecting device and method for an air jet loom, which solves the problems mentioned in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a dust collecting device at the bottom of a jet loom comprises a dust collecting hood, a material guide pipe is fixedly connected to the bottom of the dust collecting hood, a dust collecting box is fixedly connected to one end of the material guide pipe away from the dust collecting hood, a controller and a water injection pipe are arranged on the front surface of the dust collecting box, an annular plate is arranged inside the dust collecting hood, the annular plate is a cavity structure, a plurality of laser ports are equidistantly provided on the outer side of the annular plate, a water supply assembly is arranged at the connection between the dust collecting box and the annular plate, an intercepting plate is arranged inside the dust collecting box, a first filter screen is embedded and installed on the upper surface of the intercepting plate, a lifting and lowering assembly is arranged on the intercepting plate, a pushing trough and a receiving trough are correspondingly provided on both sides of the dust collecting box, a pushing trough is arranged inside the pushing trough, a sealing assembly is arranged inside the receiving trough, a receiving assembly is arranged on the outer side of the dust collecting box relative to the receiving trough, first limit plates are arranged at the four corners of the lower surface of the intercepting plate, the four first limit plates are respectively connected to the four corners of the inner side wall of the dust collecting box, and second limit plates are arranged at the positions directly above the intercepting plate relative to the four first limit plates.

[0006] By adopting the above technical scheme, before dust collection, the lower surface of the interception plate contacts the upper surface of the first limit plate, and then water is injected into the interior of the dust box through the water injection pipe until the water overflows the interception plate; when dust collection is performed, the water supply component is opened through the controller, and at this time, the water inside the dust box is introduced into the interior of the annular plate through the water supply component, and then can be sprayed onto the inner wall of the dust cover through multiple laser ports, so that the dust and fiber filaments inside the dust cover can be wetted, and then the dust and fiber filaments collected inside the dust cover enter the interior of the guide pipe with the water flow, and then fall into the interior of the dust box for collection, thereby avoiding dust and fiber filaments. The flocs are light in texture and cannot pass through the guide pipe to enter the dust box for collection. When dust and fiber flocs enter the dust box, they will fall onto the first filter screen and intercept the fiber flocs. The dust passes through the first filter screen with the water flow and accumulates at the bottom of the dust box. When there are many fiber flocs on the first filter screen, the intercepting plate is driven upward by the lifting and lowering assembly to move to the position of the pushing trough and the receiving trough. At this time, the sealing assembly is opened, and under the action of the pushing assembly, the collected fiber flocs can be pushed into the collecting assembly for collection. At the same time, the water entering the dust box can be recycled through the water supply assembly, which greatly increases the practicability of the device.

One end of the water inlet pipe passes through the interior of the dust box, and the end of the circulation pipe away from the circulation pump passes through the interior of the dust hood and extends to the interior of the annular plate. The inner side wall of the dust hood is fixedly connected to a fixing plate, and the fixing plate and the annular plate are detachably connected.

[0008] By adopting the above technical solution and providing a water supply assembly, the water inside the dust box can be introduced into the dust cover, thereby wetting the dust and fiber filaments inside the dust cover, making it easier to collect them.

[0009] As an optional solution of the lower dust collection device of an air jet loom of the present invention, an embedding groove is provided on the upper surface of the annular plate relative to the fixed plate, and a first fixing bolt is threadedly sleeved on the upper surface of the fixed plate relative to the embedding groove, and the fixed plate is detachably connected to the annular plate through the first fixing bolt.

[0010] By adopting the above technical solution and providing the embedding groove and the first fixing bolt, the annular plate can be easily disassembled and installed.

[0012] By adopting the above technical solution and providing a lifting and lowering assembly, it is convenient to lift and lower the intercepting plate, thereby facilitating the cleaning of the fiber filaments on the first filter net.

[0013] As an optional solution of the lower dust collecting device of a jet loom of the present invention, a pushing assembly includes a pushing plate, which is movably sleeved in the interior of a pushing trough, and one side of the pushing plate is fixedly connected to two second electric push rods, and the ends of the two second electric push rods away from the pushing trough are fixedly connected to a mounting frame, and the mounting frame is connected to the dust collecting box.

[0014] By adopting the above technical solution and providing a pushing assembly, the fiber filaments on the first filter net can be pushed.

[0015] As an optional solution of the lower dust collecting device of a jet loom of the present invention, the sealing assembly includes a sealing groove, which is opened on one side of the dust collecting box and is interconnected with the material receiving groove. A sealing plate is embedded in the sealing groove, and a second fixing bolt is threadedly sleeved on the sealing plate.

[0016] By adopting the above technical solution and providing a sealing component, the sealing performance of the dust collecting box can be ensured when the fiber filaments are not cleaned.

[0017] As an optional solution of the lower dust collecting device of an air jet loom of the present invention, the sealing plate is detachably connected to the dust collecting box via a second fixing bolt, and a handle is fixedly connected to the sealing plate.

[0018] By adopting the above technical solution and providing a handle, the sealing plate can be easily disassembled.

[0019] As an optional solution of the lower dust collecting device of an air jet loom of the present invention, the material receiving assembly includes a follow-up groove, which is opened at the inner bottom end of the sealing groove. The inner bottom end of the follow-up groove is fixedly connected with a receiving plate, and a collection box is placed on the upper surface of the receiving plate.

[0020] By adopting the above technical solution and setting up a material receiving component, the fiber filaments can be cleaned and collected.

[0021] As an optional solution of the lower dust collecting device of the jet loom of the present invention, a second filter is arranged directly below the interception plate, the second filter is connected to the inner wall of the dust collecting box, and the second filter is located at the top of the water inlet pipe.

[0022] By adopting the above technical solution and setting a second filter, some fiber filaments that pass through the first filter can be intercepted for a second time, thereby avoiding blockage in the water inlet pipe when the circulating pump circulates the water source inside the dust box.

[0023] As an optional solution of the lower dust collecting device of an air jet loom of the present invention, a sewage pipe is fixedly connected to the inner bottom of the dust box, a control valve is arranged on the sewage pipe, and legs are fixedly connected to the four corners of the lower surface of the dust box.

[0024] By adopting the above technical solution, by opening the control valve, the water with mud inside the dust box can be discharged through the sewage pipe, and by providing supporting legs, the dust box can be supported.

[0025] The invention discloses a method for using a lower dust collecting device of an air jet loom as follows: before collecting dust, the lower surface of the intercepting plate contacts the upper surface of the first limiting plate, and then water is injected into the dust collecting box through a water injection pipe until the water overflows the intercepting plate;

[0026] When collecting dust, the water supply component is turned on through the controller. At this time, the water in the dust box is introduced into the inside of the annular plate through the water supply component, and then can be sprayed onto the inner wall of the dust cover through multiple laser ports, so that the dust and fiber flocs inside the dust cover can be wetted, and then the dust and fiber flocs collected inside the dust cover enter the inside of the guide pipe with the water flow, and then fall into the inside of the dust box for collection. In this way, the problem that the dust and fiber flocs are light in texture and cannot enter the dust box through the guide pipe for collection can be avoided.

[0027] When dust and fiber filaments enter the dust collecting box, they will fall onto the first filter net and intercept the fiber filaments. The dust will pass through the first filter net with the water flow and accumulate at the bottom of the dust collecting box. When there are many fiber filaments on the first filter net, the interception plate will be driven upward to the position of the pushing trough and the receiving trough by the lifting and lowering assembly. At this time, the sealing assembly will be opened. Under the action of the pushing assembly, the collected fiber filaments can be pushed into the collecting assembly for collection. At the same time, the water entering the dust collecting box can be recycled through the water supply assembly.

[0028] The present invention has the following beneficial effects:

[0029] 1. The lower dust collecting device of the jet loom is provided with structures such as a water injection pipe, a water supply component, an annular plate and a laser port. When collecting fiber wadding and dust, water can be injected into the interior of the dust collecting box through the water injection pipe. Under the action of the water supply component, the water in the dust collecting box can be introduced into the interior of the annular plate, and then lasered onto the inner wall of the dust collecting cover through the laser port. In the process of water lasering, the fiber wadding and dust can be wetted, thereby avoiding the problem of being difficult to handle due to the light texture of the fiber wadding and easy to float. At the same time, the fiber wadding and dust are collected by flowing into the interior of the dust collecting box along with the water, which can avoid the problem of blockage.

[0030] 2. The lower dust collecting device of the jet loom is provided with structures such as an intercepting plate, a first filter screen, a lifting and lowering assembly, a pushing assembly and a receiving assembly. When dust and fiber flocs enter the dust collecting box, they will fall on the first filter screen and intercept the fiber flocs. The dust passes through the first filter screen with the water flow and accumulates at the bottom of the dust collecting box. When there are many fiber flocs on the first filter screen, the lifting and lowering assembly drives the intercepting plate to move upward to the position of the pushing trough and the receiving trough. At this time, the sealing assembly is opened, and under the action of the pushing assembly, the collected fiber flocs can be pushed into the receiving assembly for collection and cleaning, which greatly increases the practicability of the device.

A first filter screen 15 is embedded and installed on the upper surface of the plate 14, and a lifting and lowering assembly is arranged on the intercepting plate 14. A pushing groove 20 and a receiving groove 21 are correspondingly provided on both sides of the dust box 3. A pushing groove 20 is provided with a pushing assembly inside, and a sealing assembly is provided inside the receiving groove 21. A receiving assembly is provided on the outer side of the dust box 3 relative to the receiving groove 21. First limit plates 17 are provided at the four corners of the lower surface of the intercepting plate 14, and the four first limit plates 17 are respectively connected to the four corners of the inner wall of the dust box 3.

[0042] Before dust collection, the lower surface of the interception plate 14 contacts the upper surface of the first limit plate 17, and then water is injected into the dust box 3 through the water injection pipe 5 until the water overflows the interception plate 14;

[0043] When collecting dust, the water supply component is turned on through the controller 4. At this time, the water in the dust box 3 is introduced into the inside of the annular plate 8 through the water supply component, and then can be sprayed onto the inner wall of the dust hood 1 through the multiple laser ports 9, so that the dust and fiber lint inside the dust hood 1 can be wetted, and then the dust and fiber lint collected inside the dust hood 1 enter the inside of the guide pipe 2 with the water flow, and then fall into the inside of the dust box 3 for collection. In this way, the problem that the dust and fiber lint are light in texture and cannot enter the inside of the dust box 3 through the guide pipe 2 for collection can be avoided;

[0044] When dust and fiber filaments enter the dust box 3, they will fall onto the first filter screen 15 and intercept the fiber filaments. The dust passes through the first filter screen 15 with the water flow and accumulates at the bottom of the dust box 3. When there are many fiber filaments on the first filter screen 15, the interception plate 14 is driven by the lifting and lowering assembly to move upward to the position of the pushing trough 20 and the receiving trough 21. At this time, the sealing assembly is opened. Under the action of the pushing assembly, the collected fiber filaments can be pushed into the collecting assembly for collection. At the same time, the water entering the dust box 3 can be recycled through the water supply assembly, which greatly increases the practicality of the device.

[0045] To facilitate dust and lint collection, see Figure 1 , Figure 2 , Figure 4 and Figure 8 The water supply assembly includes a circulation pump 6, which is fixedly connected to the rear surface of the dust box 3. A circulation pipe 7 and a water inlet pipe 11 are fixedly connected to the circulation pump 6. One end of the water inlet pipe 11 passes through the interior of the dust box 3. One end of the circulation pipe 7 away from the circulation pump 6 passes through the interior of the dust cover 1 and extends to the interior of the annular plate 8. The inner side wall of the dust cover 1 is fixedly connected to a fixing plate 10, and the fixing plate 10 is detachably connected to the annular plate 8.

[0046] When in use, by turning on the circulation pump 6, under the action of the water inlet pipe 11, the water inside the dust box 3 can be introduced into the inside of the annular plate 8 through the circulation pipe 7, and then the water can be sprayed onto the inner wall of the dust hood 1 through the injection port 9. In the process of spraying, the dust and fiber lint can be wetted, so that the dust and fiber lint can be passed through the guide pipe 2 with the water flow into the inside of the dust box 3 for collection, thereby avoiding the problem of difficulty in collection due to the light texture of the dust and fiber lint. At the same time, by setting the fixing plate 10, the annular plate 8 can be fixed, thereby increasing the stability of the annular plate 8 after being placed inside the dust hood 1;

[0047] It should also be noted that an embedding groove 12 is provided on the upper surface of the annular plate 8 relative to the fixed plate 10, and a first fixing bolt 13 is threadedly sleeved on the upper surface of the fixed plate 10 relative to the embedding groove 12. The fixed plate 10 is detachably connected to the annular plate 8 via the first fixing bolt 13. By providing the embedding groove 12 and the first fixing bolt 13, the annular plate 8 can be easily disassembled and installed.

[0048] To facilitate the removal and cleaning of the collected fiber lint, please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The lifting and lowering assembly includes four first electric push rods 16, one end of the four first electric push rods 16 is connected to the upper surface of the intercepting plate 14, and the end of the first electric push rod 16 away from the intercepting plate 14 is connected to the inner top of the dust box 3, and a second limit plate 18 is arranged directly above the intercepting plate 14 relative to the four first limit plates 17. The four second limit plates 18 are respectively connected to the four corners of the inner side wall of the dust box 3, and positioning grooves 19 are provided at the four corners of the upper surface of the intercepting plate 14 relative to the four second limit plates 18; the pushing assembly includes a pushing plate 22, the pushing plate 22 is movably sleeved inside the pushing groove 20, and two second electric push rods 23 are fixedly connected to one side of the pushing plate 22, and one end of the two second electric push rods 23 is away from the pushing groove 20. The ends are fixedly connected with a mounting frame 24, which is connected to the dust collecting box 3; the sealing assembly includes a sealing groove 25, which is opened on one side of the dust collecting box 3 and is interconnected with the material receiving groove 21, and a sealing plate 26 is embedded and installed inside the sealing groove 25, and a second fixing bolt 27 is threadedly sleeved on the sealing plate 26; the sealing plate 26 is detachably connected to the dust collecting box 3 through the second fixing bolt 27, and a handle 28 is fixedly connected to the sealing plate 26; the material receiving assembly includes a follow-up groove 29, which is opened at the inner bottom end of the sealing groove 25, and a receiving plate 30 is fixedly connected to the inner bottom end of the follow-up groove 29, and a collecting box 31 is placed on the upper surface of the receiving plate 30, and the telescopic part of the first electric push rod 16 is movably sleeved on the outer side of the second limiting plate 18.

[0049] When dust and fiber lint enter the dust box 3, the first filter screen 15 on the interception plate 14 can intercept the fiber lint, and the dust passes through the first filter screen 15 along with the water flow and settles at the bottom end of the dust box 3. When there are many fiber lints intercepted on the first filter screen 15, the first electric push rod 16 drives the interception plate 14 to move upward until the positioning groove 19 provided on the interception plate 14 is clamped to the outer side of the second limit plate 18.

[0050] Then, the second fixing bolt 27 is removed, and the sealing plate 26 can be taken out from the sealing groove 25 by connecting the handle 28, so that the receiving groove 21 is exposed;

[0051] Then, the second electric push rod 23 is controlled by the controller 4 to drive the push plate 22 to move toward a position close to the receiving trough 21. When the push plate 22 moves, the lower surface of the push plate 22 fits against the upper surface of the intercepting plate 14, so that the fiber filaments collected and intercepted on the intercepting plate 14 can be pushed until the fiber filaments are pushed into the collecting box 31 for collection, thereby completing the automatic collection and cleaning of the fiber filaments.

[0052] To avoid clogging of the water inlet pipe 11, please refer to Figure 5 A second filter screen 32 is arranged directly below the interception plate 14. The second filter screen 32 is connected to the inner wall of the dust box 3. The second filter screen 32 is located at the top of the water inlet pipe 11. By setting the second filter screen 32, some fiber filaments passing through the first filter screen 15 can be intercepted for the second time, thereby avoiding blockage in the water inlet pipe 11 when the circulating pump 6 circulates the water source inside the dust box 3.

[0053] To facilitate the discharge of sewage, please refer to Figure 5 and Figure 8 A sewage pipe 33 is fixedly connected to the bottom of the dust box 3, and a control valve 34 is provided on the sewage pipe 33. Support legs 35 are fixedly connected to the four corners of the lower surface of the dust box 3. By opening the control valve 34, water with mud inside the dust box 3 can be discharged through the sewage pipe 33. By providing the support legs 35, the dust box 3 can be supported.

[0054] Working principle: before dust collection, the lower surface of the intercepting plate 14 contacts the upper surface of the first limiting plate 17, and then water is injected into the dust box 3 through the water injection pipe 5 until the water overflows the intercepting plate 14; when dust collection is carried out, the water supply component is turned on by the controller 4, and at this time, the water inside the dust box 3 is introduced into the inside of the annular plate 8 through the water supply component, and then can be sprayed onto the inner wall of the dust hood 1 through multiple laser ports 9, so that the dust and fiber flocs inside the dust hood 1 can be wetted, and then the dust and fiber flocs collected inside the dust hood 1 enter the inside of the guide tube 2 with the water flow, and then fall into the inside of the dust box 3 for collection, so that the texture of the dust and fiber flocs can be avoided The problem is that the dust and fiber filaments are too light to enter the dust collecting box 3 through the guide pipe 2 for collection; when the dust and fiber filaments enter the dust collecting box 3, they will fall onto the first filter screen 15 and intercept the fiber filaments. The dust passes through the first filter screen 15 with the water flow and accumulates at the bottom of the dust collecting box 3. When there are many fiber filaments on the first filter screen 15, the intercepting plate 14 is driven by the lifting and lowering assembly to move upward to the positions of the pushing groove 20 and the receiving groove 21. At this time, the sealing assembly is opened. Under the action of the pushing assembly, the collected fiber filaments can be pushed into the collecting assembly for collection. At the same time, the water entering the dust collecting box 3 can be recycled through the water supply assembly, which greatly increases the practicability of the device.

The sealing plate (26) is detachably connected to the dust box (3) via the second fixing bolt (27), and a handle (28) is fixedly connected to the sealing plate (26); The material receiving assembly comprises a follow-up groove (29), the follow-up groove (29) is opened at the inner bottom end of the sealing groove (25), a receiving plate (30) is fixedly connected to the inner bottom end of the follow-up groove (29), and a collection box (31) is placed on the upper surface of the receiving plate (30); A second filter screen (32) is arranged directly below the interception plate (14), the second filter screen (32) is connected to the inner wall of the dust collecting box (3), and the second filter screen (32) is located at the top end of the water inlet pipe (11); Before dust collection, the lower surface of the interception plate (14) is in contact with the upper surface of the first limit plate (17), and then water is injected into the interior of the dust collection box (3) through the water injection pipe (5) until the water overflows the interception plate (14); When collecting dust, the water supply component is turned on through the controller (4), and the water in the dust box (3) is introduced into the interior of the annular plate (8) through the water supply component, and then sprayed onto the inner wall of the dust cover (1) through the plurality of jet ports (9), thereby wetting the dust and fiber flocs in the dust cover (1), and then allowing the dust and fiber flocs collected in the dust cover (1) to flow into the guide pipe (2) and then fall into the dust box (3) for collection. In this way, the problem that the dust and fiber flocs are light in texture and cannot pass through the guide pipe (2) to enter the dust box (3) for collection can be avoided. When dust and fiber filaments enter the dust box (3), the first filter (15) on the interception plate (14) can intercept the fiber filaments, and the dust passes through the first filter (15) along with the water flow and settles at the bottom end of the dust box (3). When a large amount of fiber filaments are intercepted on the first filter (15), the interception plate (14) is driven to move upward by the first electric push rod (16) until the positioning groove (19) provided on the interception plate (14) is engaged with the outer side of the second limit plate (18); Then, the second fixing bolt (27) is removed, and the sealing plate (26) can be removed from the inside of the sealing groove (25) by connecting the handle (28), thereby exposing the material receiving groove (21); Then, the controller (4) controls the second electric push rod (23) so that it drives the push plate (22) to move toward a position close to the receiving trough (21). When the push plate (22) moves, the lower surface of the push plate (22) fits with the upper surface of the intercepting plate (14), so that the fiber lint collected and intercepted on the intercepting plate (14) can be pushed until the fiber lint is pushed into the collection box (31) for collection, thereby completing the automatic collection and cleaning of the fiber lint; At the same time, the water that enters the dust collecting box (3) can be recycled through the water supply component, which greatly increases the practicality of the device.
