[0002] Airflow felting is also known as air-laying technology, which uses airflow to separate the combed fibers from the combing components to form a fiber web. The basic method is to place the combed fibers under the centrifugal force of the combing components, and then use airflow to peel off the fibers (blowing, sucking, or both), so that the dispersed single fibers pass through an air duct, diffuse and slow down due to airflow, and gradually settle on a roller or mesh curtain with small holes to form a fiber web.

DETAILED DESCRIPTION

[0030] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0031] Combine the following Figures 1 to 9As shown, an embodiment of the present invention provides an airflow felting device for titanium fiber, including a feeding conveyor belt 1, a combing machine 2 and a fan 3. The combing machine 2 and the fan 3 are prior arts and are not described in detail herein. A feeding conveyor belt 4 is provided on the side of the fan 3, and a felting mechanism 5 is provided above the feeding conveyor belt 4. The felting mechanism 5 includes a shell 51, a felting chamber 52 is provided in the shell 51, a feed port 56 is provided at the upper end of the shell 51, and the feed port 56 is connected with the output end of the fan 3 through a pipeline. A guide plate 53 is provided at the lower end of the shell 51, a limiting roller 54 is provided at the upper end of the guide plate 53, and an extrusion roller 55 is provided on the side of the limiting roller 54, wherein the limiting roller 54, the extrusion roller 55 and the feeding conveyor belt 4 are synchronously rotated by a transmission combination of prior arts such as gears and chains to convey and extrude the titanium fiber felt. This is prior art and is not shown in the figure again. A vibration component 6 for compacting the fibers is provided on one side of the lower part of the shell 51, and a vibration component 6 for compacting the fibers is provided at the feed port 56 inside the shell 51. The guide assembly 7 for controlling the direction of the airflow comprises three guide plates 71, which are vertically arranged below the feed port 56 and are parallel to each other. The upper ends of the three guide plates 71 are provided with a rotating shaft, and the guide plates 71 are rotatably connected to the housing 51 through the rotating shaft. One end of the rotating shaft extends to the outside of the housing 51, and one end of the rotating shaft located outside the housing 51 is provided with a connecting rod 72 whose end is rotatably connected to the rotating shaft. The upper end of the housing 51 is provided with a guide motor 7 3. A rotating rod 74 is provided on the output end of the material guide motor 73, and a limiting rod 75 is provided at the end of the rotating rod 74 away from the output end of the material guide motor 73. A transmission rod is provided beside the rotating rod 74, and a limiting groove 76 is provided on the transmission rod for slidingly cooperating with the limiting rod 75. A connecting rod 77 is provided at the lower end of the transmission rod, and all the connecting rods 72 are parallel to each other and the ends are rotatably connected to the connecting rod 77. An air outlet 78 is provided beside the feed port 56, and the air outlet 78 is connected to the input end of the fan 3 through a pipeline.

[0032] When the present invention is working, the combing machine 2 disperses and combs the agglomerated titanium fibers, and blows them into the feed port 56 through the fan 3 and the pipeline. When passing through the guide assembly 7, the guide motor 73 drives the rotating rod 74 to rotate. During the process of the rotating rod 74 driving the limit rod 75 to move, the cooperation between the rotating rod 74 and the limit groove 76 will push the transmission rod and the connecting rod 77 to move left and right. During the movement of the connecting rod 77, the guide plate 71 will swing together through all the connecting rods 72. During the swinging process of the guide plate 71, the moving channel of the airflow can be changed, and then the blowing direction of the airflow can be changed. If the guide assembly 7 is not provided, after the airflow drives the titanium fibers to enter the feed port 56, it will always blow toward the bottom of the felting chamber 52. The blowing of the airflow can compact the titanium fibers in the middle, but the titanium fibers on both sides will be more fluffy than the middle, thus resulting in uneven product thickness. Therefore, the guide assembly 7 is provided, and it is constantly swung left and right during the felting process, so that the product is more uniform.

[0033] Specifically, the vibration assembly 6 includes a groove 61 arranged on one side of the bottom of the shell 51, an elastic cloth 62 for separating the felt chamber 52 and the groove 61 is arranged at the opening 10 of the groove 61, an impact plate 63 is arranged inside the groove 61, and a plurality of impact rods 64 fixedly connected to the impact plate 63 are arranged on one side of the impact plate 63, and one end of the impact rod 64 extends to the outside of the shell 51, and a connecting plate 65 connected to the impact rod 64 is arranged on the outside of the shell 51, and a plurality of push rods 66 hinged to the connecting plate 65 are arranged on the side of the shell 51. A crankshaft 67 is provided through the bracket, and the ends of all the push rods 66 are rotatably connected to the crankshaft 67. A driving motor 68 is provided on one side of the housing 51, and the output end of the driving motor 68 is connected to one end of the crankshaft 67 through a coupling; when working, the crankshaft 67 is driven to rotate by the driving motor 68, and the crankshaft 67 pulls the connecting plate 65 to continuously reciprocate through the push rod 66, and the connecting plate 65 drives the impact plate 63 to continuously reciprocate through the impact rod 64, so that the product below the felting chamber 52 can be further compacted. During the vibration process, the fluffy parts of the product will be further compacted. Then the thickness of the product is made more uniform. The reason why the elastic cloth 62 is provided in the present invention to collide with the titanium fiber is to prevent the impact plate 63 from directly contacting the titanium fiber and bringing the titanium fiber back into the groove 61. In addition, the blocking of the elastic cloth 62 can prevent the felt from being thicker at the groove 61.

[0034] Specifically, the length and width of the impact plate 63 are smaller than the length and width of the elastic cloth 62; the size of the impact plate 63 is designed as follows: Fig. 9 As shown, it is possible to prevent the impact plate 63 from directly impacting the connection between the elastic cloth 62 and the housing 51 during the collision between the impact plate 63 and the elastic cloth 62. This prevents the impact plate 63 from directly causing damage to the connection between the elastic cloth 62 and the housing 51.

[0035] Specifically, a partition cavity 8 is provided on one side of the upper end of the housing 51, a waist plate 9 is provided between the partition cavity 8 and the felt-forming chamber 52, an opening 10 is provided on the waist plate 9, and the air outlet 78 is connected with the felt-forming chamber 52 through the partition cavity 8 and the waist plate 9. The waist plate 9 separates the felt-forming chamber 52 and the air outlet 78 as much as possible to prevent the titanium fibers floating in the felt-forming chamber 52 from directly entering the air outlet 78.

[0036] Specifically, a baffle 11 is provided at the opening 10 and is curved downward. Figure 7 As shown, when the material guide assembly 7 rotates to the side facing the opening 10 , the airflow will rotate and flow downward through the setting of the baffle 11 , thereby preventing the titanium fibers fed with the airflow from entering the partition cavity 8 and the air outlet 78 from the opening 10 .

[0037] Specifically, a filter screen 12 is provided at the opening 10, and the filter screen 12 is provided to prevent titanium fibers from entering the partition chamber 8 and the air outlet 78 from the opening 10. When the present invention is working, the titanium fibers are transported by the fan 3, and then the air in the felt-forming chamber 52 is led back to the fan 3 through the pipeline by the air outlet 78, which, on the one hand, avoids excessive air pressure in the felt-forming chamber 52, and on the other hand, does not need to further use the negative pressure fan 3 to extract the air in the felt-forming chamber 52, thereby saving energy.

[0038] Specifically, a first connecting door 13 for taking out the filter 12 is provided on one side of the shell 51 . The filter 12 can be cleaned by opening the first connecting door 13 to prevent the titanium fibers from excessively sticking to the filter 12 .

[0039] Specifically, a connecting cylinder 14 is provided at the upper end of the shell 51, a piston 15 is provided in the connecting cylinder 14, a movable rod 16 is provided at the upper end of the piston 15, the upper end of the movable rod 16 extends to the top of the shell 51, an extension plate 17 is provided at the upper end of the movable rod 16, a connecting rope 18 fixedly connected to the extension plate 17 is provided at the lower end of the extension plate 17, a handle 19 is provided at the lower end of the connecting rope 18, a spring 20 is provided between the extension plate 17 and the shell 51, the spring 20 is sleeved on the movable rod 16, an air outlet 21 is provided at the lower end of the connecting cylinder 14, and the air outlet 21 is arranged toward the filter 12. During operation, the setting of the baffle 11 can prevent titanium fibers from entering the opening 10 and being adsorbed on the filter 12 as much as possible, but such a situation may not be completely avoided. In order to avoid stopping the machine to clean the filter 12 during operation, the handle 19 can be pulled to drive the extension plate 17 downward through the connecting rope 18. The movable rod 16 and the piston 15 move downward quickly, so that the air in the connecting cylinder 14 quickly forms an airflow to purge the filter 12 below, and the filter 12 can be cleaned during the continuous operation of the present invention, which is simple to operate. In addition to the above embodiments, the movable rod 16 can also be connected to a driving device for automatic operation, such as a cylinder, an electric push rod, etc.

[0040] Specifically, the side wall of the housing 51 opposite to the vibration assembly 6 is provided with a second connecting door 22 for cleaning the felt-forming chamber 52. The felt-forming chamber 52 can be cleaned by opening the second connecting door 22.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
