Description

Technical Field

[0001] This utility model relates to the field of fiber sorting technology, and in particular to a fiber blowing mechanism. Background Technology

[0002] Fiber is the most basic raw material in the textile industry. It is composed of thin, flexible solid substances and is used in textile processing. In order to improve the quality of textile products, ensure product purity and characteristics, and achieve effective recycling and reuse of waste textiles, it is necessary to separate lightweight and heavy fibers.

[0003] Currently, the commonly used method is to use gravity settling and airflow for layer separation. However, when using gravity settling and airflow separation in the traditional way, most of them use continuous gas to separate the mixed fibers of light and heavy materials into layers. In the continuous gas flow, the speed and direction of the airflow are not completely uniform, which will cause the movement trajectory of the fibers in the airflow to deviate. This makes it impossible for some light or heavy fibers to be accurately separated into layers, resulting in poor separation quality.

[0004] Therefore, this application provides a fiber blowing mechanism to solve the problems mentioned in the background art. Utility Model Content

[0007] A further improvement of this utility model is that: support columns are respectively provided on both sides of the discharge end of the conveyor belt, support plates are provided on the top surface of the support columns, bearing seats are provided on the support plates, and the bearing seats are respectively rotatably connected to the two ends of the limiting roller.

[0008] A further improvement of the present invention is that the air outlet includes a horizontal cylinder, an opening is provided in the upper middle part of the cylinder body away from the conveyor belt, and upwardly inclined and parallel guide plates are respectively provided at both ends of the opening body. A vertical top plate is provided on the top of the guide plate, and a number of air outlet holes are evenly provided on the top plate.

[0009] A further improvement of this utility model is that the diameter of the air outlet is 0.5~2 mm, the diameter of the cylinder is 3~10 cm, the center of the cylinder is aligned with the center of the roller at the discharge end of the conveyor belt, and the vertical distance between the bottom surface of the cylinder and the discharge end of the conveyor belt is 1 cm.

[0010] A further improvement of this utility model is that the angle between the guide plate and the horizontal plane is 45 to 60 degrees, and the outer edge of the top surface of the guide plate near the conveyor belt is aligned vertically with the outer end surface of the conveyor belt.

[0011] A further improvement of this utility model is that: the two ends of the cylinder are closed, and square fixing plates are welded to the two end faces of the cylinder respectively. The square fixing plates are provided with mounting holes, and bolts are inserted into the mounting holes to connect with the inner side of the support column.

[0012] A further improvement of the present invention is that the pipeline includes a main pipeline, one end of which is connected to a pulse valve, and the other end of which is connected to the middle of the bottom of a horizontal pipeline. Vertical branch pipes are respectively installed at both ends of the horizontal pipeline, and the other end of each branch pipe is connected to the bottom of a cylinder.

[0013] A further improvement of this utility model is that the diameter of the main pipeline and the horizontal pipeline are the same, and the diameter of the cylinder is 1 to 3 times the diameter of the pipeline.

[0014] A further improvement of this utility model is that the pulse valve has a blowing time of 1 to 3 seconds and a blowing interval of 1 second.

[0015] A further improvement to the technical solution of this utility model is that the air pump and the air tank are connected by an air pipe.

[0016] By adopting the above technical solution, this utility model has the following beneficial effects:

[0017] 1. This utility model provides a fiber blowing mechanism. The blowing mechanism adopts a pulse airflow mechanism design. By controlling the blowing time and interval of the pulse valve, and in conjunction with the evenly distributed air outlet holes on the air outlet cylinder, the gas can accurately blow and separate the fibers on the conveyor belt. The instantaneous high pressure characteristics of the pulse airflow can overcome the difference in fiber inertia. Light fibers are effectively blown to the upper layer, while heavy impurities settle to the lower layer due to gravity and detach.

[0031] The present invention will be further explained below with reference to specific embodiments.

[0032] like Figures 1-7As shown, this embodiment provides a fiber blowing mechanism, including a frame 1, a conveyor belt 2 mounted on the frame 1, and limiting rollers 3 and a pulse airflow mechanism 4 respectively positioned above and below the discharge end of the conveyor belt 2. The pulse airflow mechanism 4 includes an air pump 5 located on one side of the frame 1, the air pump 5 being positioned on top of an air tank 6, and the air pump 5 and air tank 6 being connected by an air pipe 51. The air outlet pipe at the top of the air tank 6 is connected to a pulse valve 7. The blowing time of the pulse valve 7 is 1-3 seconds, and the blowing interval is 1 second. The intermittent blowing of the pulse valve 7 forms an airflow pulse peak, causing the lightweight fibers to obtain an acceleration difference, resulting in a certain greater throwing height compared to the heavy fibers, thus achieving... The dynamic stratification system uses existing equipment such as air pump 5, air tank 6, and pulse valve 7. The specific structure will not be described in detail here. Air pump 5 compresses air to generate compressed gas with a certain pressure and flow rate, providing a power source for the entire blowing mechanism. The compressed gas enters air tank 6 through air pipe 51. Air tank 6 plays a role in buffering and stabilizing the airflow, ensuring that the airflow entering pulse valve 7 is more stable. Pulse valve 7 is connected to the bottom of air outlet cylinder 9 through pipe 8. Air outlet cylinder 9 is set parallel to the bottom of the discharge end of conveyor belt 2. Multiple air outlet holes 10 are evenly arranged on the top surface of air outlet cylinder 9. The gas blown out of air outlet holes 10 blows and separates the fibers conveyed by conveyor belt 2. The blowing mechanism controls the blowing time and interval of the pulse valve 7, and works in conjunction with the evenly distributed air outlets 10 on the air outlet cylinder 8 to enable the gas to accurately blow away and separate the fibers falling on the conveyor belt. The instantaneous high pressure characteristics of the pulse airflow can overcome the difference in fiber inertia. Lightweight fibers are effectively blown away to the upper layer, while heavy impurities are separated from the lower layer due to gravity. This reduces the deviation of fiber trajectory caused by uneven airflow and improves the accuracy of separating lightweight and heavy fibers into layers.

[0033] like Figure 2 As shown, in this embodiment, support columns 11 are respectively provided on both sides of the discharge end of the conveyor belt 2. Support plates 110 are provided on the top surface of each support column 11, and bearing seats 111 are provided on the support plates 110. The bearing seats 111 are rotatably connected to both ends of the limiting roller 3. The limiting roller 3 is a driven roller that passively rotates with the movement of the fibers, working in conjunction with the conveyor belt 2. It can effectively constrain the thickness of the fiber layer on the conveyor belt 2, preventing the fiber layer from being too thick or uneven, ensuring a more uniform distribution of fibers on the conveyor belt 2, and improving the effect of blowing, sealing, and separating the layers.

[0034] like Figures 3-7As shown, in this embodiment, the air outlet 9 includes a horizontal cylinder 91. The cylinder 91 is closed at both ends. The design of the cylinder 91 avoids excessive concentration of airflow in localized areas, thus preventing excessive fiber dispersion or separation from the conveyor belt 2 in certain areas and improving the uniformity of the dispersion effect. Square fixing plates 911 are welded to both ends of the cylinder 91. The square fixing plates 911 have mounting holes 912, through which bolts are inserted to connect to the inner surface of the support column 11. An opening 92 is provided in the upper middle part of the cylinder 91 body away from the conveyor belt 2. Upwardly inclined and parallel guide plates 93 are provided at both ends of the opening 92 body. A vertical top plate 94 is provided on the top of the guide plates 93, and several air outlet holes 10 are evenly distributed on the top plate 94. The diameter of the air outlet holes 10 is 0.5~2 mm, and the diameter of the cylinder 91 is 3~10 cm. The center of the cylinder 91 is aligned with the center of the roller at the discharge end of the conveyor belt 2, and the vertical distance between the bottom surface of the cylinder 91 and the discharge end of the conveyor belt 2 is 1 cm. The guide plate 93 has an angle of 45-60 degrees with the horizontal plane. The outer edge 931 of the top surface of the guide plate 93 closest to the conveyor belt 2 is aligned vertically with the outer end face of the conveyor belt 2. The opening 92 is located on the side of the cylinder 91 away from the conveyor belt 2. Together with the upwardly inclined guide plate 93, it guides the airflow to be evenly distributed along the entire width of the conveyor belt, avoiding airflow concentration and ensuring good dispersion and separation effects. The guide plate has an angle of 45-60 degrees with the horizontal plane, and the outer edge of the guide plate closest to the conveyor belt is aligned with the outer end face of the conveyor belt, so that the airflow impacts the fibers at the optimal angle, enhancing the dispersion and separation effect. Several air outlets 10 are evenly arranged on the top plate 94, so that the airflow is evenly sprayed onto the fibers, preventing localized excessively strong or weak airflow and improving the dispersion and separation effect.

[0035] like Figure 4 As shown, in this embodiment, the pipeline 8 includes a main pipeline 81, one end of which is connected to the pulse valve 7, and the other end of which is connected to the middle of the bottom of the horizontal pipeline 82. Vertical branch pipes 83 are respectively provided at both ends of the horizontal pipeline 82, and the other end of the branch pipes 83 is connected to the bottom of the cylinder 91. Multiple branch pipes 83 can be provided, with one end uniformly and vertically connected to the top surface of the horizontal pipeline 82, and the other end connected to the bottom surface of the cylinder 91. The main pipeline 81 and the horizontal pipeline 82 have the same diameter, and the diameter of the cylinder 91 is 1 to 3 times the diameter of the pipeline 8. The main pipeline 81 connects to the center point of the horizontal pipeline 82, and together with the evenly distributed branch pipelines 83, forms a symmetrical flow distribution system to ensure that the pulsed airflow is evenly distributed to the cylinder 91, reducing flow deviation and avoiding local overshoot or undershoot. The main pipeline 81 and the horizontal pipeline 82 have the same diameter to reduce flow resistance. The diameter of the cylinder 91 is designed to be 1 to 3 times the diameter of the pipeline to form a buffer cavity, reduce sudden changes in airflow velocity, weaken the energy dissipation caused by pulse impact, maintain stable airflow pressure, and make the fiber layer separation more complete.

[0036] This utility model also provides a working principle for a fiber blowing mechanism: the user places the fiber to be separated on the conveyor belt 2. The conveyor belt 2 rotates, and the fiber moves to the discharge end of the conveyor belt 2. After the fiber roller 3 above the discharge end of the conveyor belt 2 limits and controls the thickness, the fiber continues to move forward with the conveyor belt 2 and falls down from the conveyor belt 2. At this time, the air pump 5 is in the start state. The compressed air of the air pump 5 enters the air tank 6. After passing through the pulse valve 7, pipeline 8, and air outlet 9 from the air tank 6, it is sprayed out from the air outlet 10 on the top plate 94 of the air outlet 9, which blows and separates the downward falling fiber into layers.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the 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 or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
