Description

Technical Field

[0001] The utility model relates to airflow laying equipment, in particular to non-woven airflow laying equipment for composite fiber felt, belonging to the technical field of composite fiber felt production. Background Art

[0002] In the prior art, for example, the utility model with application number 202320454019.8 discloses an airflow paving equipment with a screen roller. In order to ensure the accuracy of the material in the transverse direction to the production direction and stabilize the airflow, a cylindrical rotating body is arranged outside the air gate grille to replace the vibrating screen. The cylindrical rotating body can be a cylindrical rotating body, and a partition corresponding to the air gate grille is arranged on the cylindrical rotating body. During the paving process, the cylindrical rotating body can not only stabilize the airflow like the screen, but also reduce the lateral movement of the material caused by the unstable airflow within the range of the cylindrical rotating body through the partition arranged inside the cylindrical rotating body. In addition A plurality of partitions are arranged horizontally in the cylindrical rotating body, and a layer of screen is wrapped in the circumferential direction of the outer side to form a cylindrical rotating body; the cleaning device of this scheme can be of various types, for example: a plurality of small hammers with lines are arranged in the axial direction of the cylindrical rotating body axis inside the cylindrical rotating body (or each small hammer with line corresponds to a partition space, and the small hammers with lines at different axial positions are evenly arranged along the circumference of the cylindrical rotating body axis). During the rotation of the cylindrical rotating body, the lines of the small hammers with lines will be coiled up by the cylindrical rotating body axis and then tightened with the small hammers. After being released for a moment, the small hammers hit the screen surface due to gravity, thereby realizing rotation and vibration at the same time, so that the materials adhered to the screen surface fall off during the vibration.

[0003] Similar to the above application, there are still some shortcomings:

[0004] During the process of material falling, the rotating body can only vibrate once after one rotation, and the material cannot be shaken off evenly. In addition, the synchronous operation of the air supply device and the rotating body cannot be ensured, which affects the paving effect.

[0005] Therefore, a non-woven air-laying device for composite fiber felt is designed to optimize the above-mentioned problems. Utility Model Content

[0025] Overall working principle: During use, materials are injected from the feed inlet 3, and at the same time, the blowing device 2 blows air to the inside of the paving chamber 1. The gas pushes the material toward the partition 6. The partition 6 stabilizes the airflow and rotates simultaneously with the rotating rod 5. During the rotation of the screen 7, the slide bar 8 is driven to make a circular motion. When the slide bar 8 rotates, the slider 10 slides along the length direction of the slide bar 8 and reciprocates to hit the positioning block 9 and the screen 7. During the single-week rotation of the screen 7, the screen 7 will vibrate multiple times, thereby improving the effect of shaking off the material.

[0026] In this embodiment, four groups of sliding rods 8 are provided on the side walls of the screen 7 between adjacent partitions 6, and the angle between adjacent sliding rods 8 is 90°.

[0027] Local working principle: four groups of sliding rods 8 are evenly distributed on the screen 7, so that the inner side can be evenly vibrated during the rotation of the screen 7.

[0033] Partial working principle: When the motor 12 drives the shaft 13 to rotate, it will also control the rotation of the driving wheel 19. The driving wheel 19 cooperates with the belt 18 and the driven wheel 17 to control the rotation of the reducer 16, and controls the rotating rod 5 to rotate slowly.

[0034] In this embodiment, a protective cover is provided between the outer side of the paving chamber 1 and the installation box 11, and the reducer 16, the driven wheel 17 and the belt 18 are all located inside the protective cover.
