Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically to an airflow web forming dust removal device. Background Technology

[0002] Airflow web forming is a process that uses airflow to detach combed fibers from the combing components to form a web. The basic method involves using airflow (blowing, suction, or a combination of both) to separate the combed fibers under centrifugal force from the combing components. The dispersed individual fibers then pass through an air duct, where the airflow diffuses and slows them down, causing them to gradually settle onto perforated rollers or screens to form a web. However, during production, the fibers inevitably generate some cotton dust due to the airflow. This dust can affect the production environment and the quality of the web.

[0003] Chinese patent CN220952376U discloses a dust cage mechanism for an airflow web forming machine, including an airflow web forming machine. A hopper is connected and fixedly connected to the top of the airflow web forming machine. Two high-speed spiked rollers are arranged in the lower part of the hopper, with their front and rear ends penetrating the hopper and the airflow web forming machine and rotatably connected to it. Air inlet pipes are connected and fixedly connected to the upper left and right sides of the airflow web forming machine, and these inlet pipes are also connected and fixedly connected to the hopper. Dust and impurities in the raw material are collected in a collection tank by the unidirectional airflow from a first and second suction fan, passing through uniform holes in the web forming dust cage. The collected dust then enters the dust collection box through a drain pipe, where it undergoes initial dust removal by filter cotton, followed by final dust removal by water spraying from nozzles. Wastewater is discharged from the equipment through a drain hole. After a period of use, the door is opened by pulling the handle to replace the filter cotton, ensuring effective dust removal. However, this device still has the following problems:

[0004] 1. During filtration, cotton lint enters the dust collection box through the air duct and is first filtered horizontally through the filter cotton before being wetted and dusted. The fibers contained in the cotton dust will quickly clog the gaps in the filter cotton, requiring frequent manual replacement of the filter cotton, thus reducing work efficiency.

[0005] 2. During the airflow web formation process, due to quality requirements of the finished product, it is necessary to filter out fibers of different lengths. This device cannot adjust the filtering of fibers of different lengths.

[0006] Based on this, the present invention designs an airflow mesh dust removal device to solve the above problems. Utility Model Content

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0037] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0038] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-7 An airflow forming dust removal device includes a housing 1, a first roller 2, a second roller 3, an adjustable suction fiber size dust cage mechanism 4, a self-cleaning dust removal mechanism 5, a dust collection box 6, an air inlet pipe 7, and a fan 8. The bottom of the housing 1 is equipped with an adjustable suction fiber size dust cage mechanism 4, which is used to form the loosened raw material into a net through airflow and remove dust and short fibers. The housing 1 is rotatably connected to a first roller 2 and a second roller 3, which are used to transport the material on the adjustable suction fiber size dust cage mechanism 4 to the outside of the housing 1. The first roller 2 is higher than the second roller 3, and the second roller 3 is higher than the adjustable suction fiber size dust cage mechanism 4.

[0039] The adjustable suction fiber size dust cage mechanism 4 is connected to the dust collection box 6 at the left end through the air inlet pipe 7. The top of the dust collection box 6 is fixedly equipped with a fan 8 for extracting cotton dust and short fibers flying inside the outer shell 1. The dust collection box 6 is equipped with a self-cleaning dust collection mechanism 5 for dust reduction treatment of cotton dust drawn into the dust collection box 6.

[0040] The self-cleaning dust removal mechanism 5 includes a baffle fan 52, a floating filter assembly 55, and a spray head 57. An air inlet 51 is located at the bottom rear of the dust collector 6. An air inlet pipe 7 connects to the interior of the dust collector 6 through the air inlet 51. A baffle fan 52 is installed in the middle of the dust collector 6 to turbulently swivel the incoming air. The baffle fan 52 is rotatably connected to the inner wall of the dust collector 6 via a rotating shaft. The floating filter assembly 55 is installed inside the dust collector 6 and located above the baffle fan 52. The end of the baffle fan 52 away from the rotating shaft can abut against the bottom of the floating filter assembly 55 when rotating. Next, a ball bearing is provided at the end of the fan blades away from the shaft on the deflector fan 52. The ball bearing is used to reduce the hard friction between the fan blades and the bottom of the floating filter assembly 55, thereby increasing the service life of the floating filter assembly 55. An air outlet 53 is provided on the top of the dust collector 6, and the air inlet of the fan 8 is connected to the air outlet 53. A drain outlet 54 is provided at the bottom front side of the dust collector 6. Multiple spray heads 57 are fixedly installed on the inner wall of the dust collector 6 above the floating filter assembly 55. The spray heads 57 are connected to the external water pipes. The spray heads 57 are atomizing nozzles, which can better reduce dust.

[0041] In this invention, the top of the inner shell 1 is provided with a dispersing structure (not shown in the diagram) for dispersing and fluffing the raw materials. The operator places the raw materials into the inner shell 1 through the feed inlet at the top of the shell 1 to disperse and fluff them. Then, under the suction force of the blower 8, the fluffy fibers are formed into a net by the airflow and adhere to the upper part of the adjustable fiber-size suction dust cage mechanism 4. The finished product is conveyed out of the shell 1 by the first roller 2 and the second roller 3. The adjustable fiber-size suction dust cage mechanism 4, under the action of the blower 8, has an adsorption function for scattered cotton dust and short fibers. The cotton dust and short fibers sucked into the adjustable fiber-size suction dust cage mechanism 4 pass through the air intake... Pipe 7 enters the dust collection box 6. The baffle fan 52 starts to rotate under the action of wind force, which disperses the incoming airflow. Since the air outlet 53 is at the top of the dust collection box 6, the cotton dust and short fibers will fly upward and then settle under the spray action of the spray head 57. At the same time, the ends of multiple fan blades with ball bearings on the baffle fan 52 take turns hitting the bottom of the floating filter assembly 55, causing the small amount of cotton dust and short fibers adhering to the floating filter assembly 55 to fall down. The settled cotton dust and short fibers are discharged from the dust collection box 6 through the drain port 54.

[0042] This invention can achieve the settling of cotton dust and short fibers scattered during the airflow web formation process through the self-cleaning dust removal mechanism 5, and can also self-clean the filter screen 551, reducing the impact on work efficiency caused by frequent replacement of the filter screen 551.

[0043] In some embodiments, the floating filter assembly 55 includes a filter 551, a second spring 552, and a guide rod 553. The filter 551 is slidably installed inside the top of the dust collector 6 and located above the baffle fan 52. The filter 551 is slidably connected to the inner wall of the dust collector 6 via the guide rod 553. Two guide rods 553 are fixedly installed on the inner top wall of the dust collector 6. The two guide rods 553 are symmetrically and vertically arranged on the inner top walls of the front and rear sides of the dust collector 6. The second spring 552 is wrapped around the outer wall of the guide rod 553. The bottom of the second spring 552 is fixedly connected to the top surface of the filter 551, and the top of the second spring 552 is fixedly connected to the top of the guide rod 553.

[0044] In this invention, multiple blades on the deflector fan 52, each with ball bearings, alternately strike the bottom surface of the filter screen 551. This vibration causes the filter screen 551 to vibrate and shake off dust and short fibers. The filter screen 551 then slides upwards along the guide rod 553, and after the fan blades have rotated, the spring force of the second spring 552 pushes the filter screen 551 back to its original position. This self-cleaning mechanism reduces the impact on work efficiency caused by frequent filter screen replacements.

[0045] In some embodiments, the adjustable suction fiber size dust cage mechanism 4 includes an inner dust cage 41, an outer dust cage 42, and a cage hole size adjustment component 45. The left and right ends of the outer dust cage 42 are fixedly connected to the left and right ends of the bottom of the inner shell 1, respectively. The inner dust cage 41 is fitted inside the outer dust cage 42, and the outer wall of the inner dust cage 41 is rotatably connected to the inner wall of the outer dust cage 42. The left end of the inner dust cage 41 is rotatably connected to the left end of the inner shell 1, and the right end of the inner dust cage 41 is connected to the cage hole size adjustment component 45. Multiple sets of inner dust cage holes 43 are linearly arranged on the outer wall of the inner dust cage 41, and each set of inner dust cage holes 43 is a plurality of inner dust cage holes 43 distributed in a circumferential array. Multiple sets of outer dust cage holes 44 are linearly arranged on the outer wall of the outer dust cage 42, and each set of outer dust cage holes 44 is a plurality of outer dust cage holes 44 distributed in a circumferential array. Both the inner dust cage holes 43 and the outer dust cage holes 44 are through holes, and the inner dust cage holes 43 and the outer dust cage holes 44 are the same size and have the same shape.

[0046] The cage size adjustment assembly 45 includes a square guide rod 451, a first spring 452, a first toothed block 453, a rotating shaft 454, a rotating wrench 455, and a second toothed block 456. The left end of the square guide rod 451 passes through the right side wall of the inner dust cage 41 and is slidably connected to the inner dust cage 41. The first spring 452 is sleeved on the outside of the right end of the square guide rod 451. The left end of the first spring 452 is fixedly connected to the outer wall of the right end of the inner dust cage 41. The right ends of the first spring 452 and the right ends of the square guide rod 451 are both connected to the second toothed block 456. The left end of 53 is fixedly connected, and the first tooth block 453 and the second tooth block 456 are meshed and connected. The right end of the second tooth block 456 is fixedly connected to the inner wall of the right side of the outer shell 1. The rotating shaft 454 passes through the second tooth block 456 from left to right, and the rotating shaft 454 and the second tooth block 456 are rotated and slidably connected. The left end of the rotating shaft 454 is fixedly connected to the right end of the first tooth block 453. The right end of the rotating shaft 454 rotates and extends through to the outer right side of the outer shell 1 and is fixedly connected to one end of the rotating wrench 455. The rotating shaft 454 is slidably connected to the right side wall of the outer shell 1.

[0047] In this invention, when it is necessary to adjust the effective suction diameter of the dust cage, the operator pushes the rotary wrench 455 to the left. The rotary wrench 455 pushes the toothed block 453 to the left through the rotating shaft 454. The toothed block 453 presses the spring 452 to the left and causes the square guide rod 451 to slide against the right side wall of the inner dust cage 41. At this time, the engagement between the toothed block 453 and the toothed block 456 is canceled. Then, the rotary wrench 455 is rotated. The rotary wrench 455 drives the inner dust cage 41 to rotate through the rotating shaft 454, the toothed block 453 and the square guide rod 451, so that the inner dust cage hole 43 and the outer dust cage hole 44 slide relative to each other. When the inner dust cage hole 43 and the outer dust cage hole 44 are completely overlapped, the hole diameter is adjusted to the maximum. After the hole diameter is adjusted to the required size, the push force on the rotating shaft 454 to the left is released, and the elastic force of the spring 452 pushes the toothed block 453 to reset and engage with the toothed block 456 to lock the angle.

[0048] This invention enables the rapid adjustment of the cage size to filter fibers according to the product's fiber length requirements via the cage size adjustment component 45.

[0049] In some embodiments, the size of the air outlet 53 is matched with the size of the air inlet of the fan 8 to ensure better airflow.

[0050] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
