Description

Technical Field

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

[0002] High-performance fiber-reinforced asphalt macadam flexible crack-resistant seal (hereinafter referred to as high-performance flexible crack-resistant seal) technology uses mechanical equipment such as four-synchronous intelligent seal vehicles to spread a certain amount of fiber, modified asphalt binder, and controlled-gradient crushed stone simultaneously through high-precision, mechanized, and intelligent control methods. This is then compacted by a road roller (or by natural traffic) to form a flexible crack-resistant seal. Currently, fiber spraying mechanisms are installed between two rows of asphalt spraying pipes to spray short, cut fibers onto the road surface. However, these short fibers tend to clump together and distribute unevenly during their descent. Utility Model Content

[0003] This invention provides a fiber fabric mechanism to solve the problem of fiber clumping and uneven distribution during the falling process.

[0004] This utility model provides a fiber fabric mechanism, including a fiber conveying pipe, a discharge chamber connected to the lower part of the fiber conveying pipe, the fiber conveying pipe being used to spray fibers into the discharge chamber, a discharge port being provided at the lower end of the discharge chamber, air inlets being provided on both sides of the discharge chamber, a high-pressure air supply device being connected to the air inlets, a guide plate being provided between the air inlets and the fiber conveying pipe, the air outlet of the air inlets facing one end of the guide plate, and the other end of the guide plate extending to the discharge port of the fiber conveying pipe.

[0005] Preferably, the lower side of the guide plate is provided with an arc surface.

[0006] Preferably, the air intake pipe has an L-shaped structure, and the air outlet of the air intake pipe faces upward.

[0007] Preferably, the material discharge chamber is provided with multiple fiber conveying pipes.

[0008] Preferably, the material discharge chamber has a rectangular structure, and the air inlet pipe is located at the upper end of the material discharge chamber.

[0009] Preferably, there are multiple material discharge chambers, and the arrangement direction of the material discharge chambers is the same as the arrangement direction of the fiber conveying pipe.

[0010] Preferably, two adjacent material discharge cavities are staggered.

[0011] Compared with the prior art, the present invention has a simple structure and is easy to implement. The air inlet pipes on both sides of the feeding chamber blow high-pressure gas to the guide plate. The guide plate guides the high-pressure gas from both sides to the outlet of the fiber conveying pipe to form a vortex. When the fiber ejected from the fiber conveying pipe is drawn into the vortex, it can be fully dispersed, and the fiber distribution becomes more uniform. Secondly, the vortex can effectively slow down the ejection speed of the fiber, resulting in better fiber fabrication. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] See attached document Figure 2This embodiment provides a fiber fabric mechanism, including a fiber conveying pipe 1. A discharge chamber 2 is connected to the lower part of the fiber conveying pipe 1. The fiber conveying pipe 1 is used to spray fibers into the discharge chamber 2. The aperture of the discharge chamber 2 is much larger than the aperture of the fiber conveying pipe 1. A discharge port 21 is provided at the lower end of the discharge chamber 2. Air inlets 3 are respectively provided on both sides of the fiber conveying pipe 1 in the discharge chamber 2. A high-pressure air supply device is connected to the air inlets 3. A guide plate is provided between the air inlets 3 and the fiber conveying pipe 1. The air outlet 31 of the air inlets 3 faces one end of the guide plate, and the other end of the guide plate extends to the discharge port of the fiber conveying pipe 1. In this invention, the air inlets 3 blow high-pressure gas to the guide plate, and then the gas is guided by the guide plate to the discharge port of the fiber conveying pipe 1. The high-pressure gas on both sides interacts at the discharge port of the fiber conveying pipe 1 to form a vortex, which disrupts the fibers conveyed by the fiber conveying pipe 1, allowing them to interweave and distribute evenly. At the same time, vortexes can effectively slow down the fiber ejection speed, making the fiber fabric more stable and reliable.

[0019] As another embodiment of this utility model: the lower side of the guide plate is provided with an arc surface 4. This structural design facilitates the guidance of high-pressure gas to form a vortex at the outlet of the fiber conveying pipe 1.

[0020] As another embodiment of this utility model: the air inlet pipe 3 has an L-shaped structure and the air outlet 31 of the air inlet pipe 3 faces upward. This arrangement makes the air inlet pipe 3 in the material discharge chamber 2 vertically distributed, which can effectively avoid occupying too much space in the material discharge chamber 2.

[0021] As another embodiment of this utility model: multiple fiber conveying pipes 1 are distributed on the discharge chamber 2, and the fibers ejected from multiple fiber conveying pipes 1 can be dispersed simultaneously through one discharge chamber 2.

[0022] As another embodiment of this utility model: the dropping chamber 2 has a rectangular structure, and the air inlet pipe 3 is located at the upper end of the dropping chamber 2. During the process of fiber falling, this structural design allows the fiber to be fully dispersed in the dropping chamber 2.

[0023] As another embodiment of this utility model: refer to the appendix Figure 1 There are multiple material discharge chambers 2, and the arrangement direction of the material discharge chambers 2 is the same as that of the fiber conveying pipe 1.

[0024] As another embodiment of this utility model: two adjacent material drop chambers 2 are staggered and the turbine formed in the material drop chamber 2 can interfere with the airflow in the vicinity. This structural design can effectively reduce the interference with the material distribution in the adjacent material drop chamber 2.

[0025] This utility model has a simple structure and is easy to implement. The air inlet pipes 3 on both sides of the feeding chamber 2 blow high-pressure gas to the guide plate. The guide plate guides the high-pressure gas from both sides to the outlet of the fiber conveying pipe 1 to form a vortex. When the fiber sprayed out of the fiber conveying pipe 1 is drawn into the vortex, it can be fully dispersed, and the fiber distribution becomes more uniform. Secondly, the vortex can effectively slow down the fiber spraying speed, making the fiber fabric distribution better.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not 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 do 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.
