Description

Technical Field

[0001] This utility model relates to the field of felt production technology, and more specifically, it relates to a coating device for felt production. Background Technology

[0002] Felt is a thick, soft, and multifunctional nonwoven material, primarily made from natural or synthetic fibers through a series of complex processes. These fibers can be animal fibers such as wool and camel hair, or synthetic fibers such as polyester and polypropylene. During the manufacturing process, the fibers are first combed and arranged in parallel, and then interwoven and tightly bonded together through mechanical or physical methods such as needle punching, hydroentangling, or hot pressing, forming a dense fabric.

[0003] Some felt fabrics require coating during the production process, but most of the existing coating nozzles are installed in fixed positions, which can easily lead to uneven coating and affect the quality of the felt fabric. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an infeed coating device for felt production.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coating device for felt production, comprising an outer ring, a drive mechanism, and a rotation mechanism;

[0006] A ring rail is fixedly connected to the inner wall of the outer ring, and multiple sliders are slidably connected to the ring rail. All of the sliders are fixedly connected to the inner ring. Multiple support plates are fixedly connected to the inner wall of the inner ring. A rotating cylinder is rotatably connected to each support plate. A nozzle is fixedly connected inside each rotating cylinder. A diverter pipe is connected to each nozzle. The ends of the multiple diverter pipes away from the nozzles are connected to the diverter head. A first rotary joint is connected to the inlet of the diverter head.

[0007] The drive mechanism is mounted on the outer ring and is used to drive the inner ring to rotate.

[0008] The rotation mechanism is installed on multiple rotating drums, and the rotation mechanism is used to drive the multiple rotating drums to rotate.

[0009] Preferably, the drive mechanism includes a motor, a first gear, and an external gear ring. The motor is mounted on the outer ring, and the first gear is fixedly connected to the output shaft of the motor. The external gear ring is meshed with the first gear, and the external gear ring is fixedly connected to the inner ring.

[0010] Preferably, the rotation mechanism includes an internal gear ring and a second gear. The internal gear ring is fixedly connected to an outer ring, and a plurality of second gears are meshed on the internal gear ring. The plurality of second gears are respectively fixedly connected to a plurality of rotating drums.

[0011] Preferably, a second rotary joint is installed between the nozzle and the diverter pipe.

[0012] Preferably, multiple support legs are fixedly connected to the outer ring.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The outer ring is mounted above the conveyor belt of the felt cloth. The inner ring is driven to rotate along the ring track by the drive mechanism. The inner ring drives the multiple nozzles on it to rotate. The first rotary joint ensures the normal delivery of the coating liquid during the rotation. The multiple nozzles coat the felt cloth during the rotation, thereby effectively improving the uniformity of the coating and improving the quality of the felt cloth.

[0015] 2. During the process of the inner ring driving the rotating drum to rotate, the rotating drum will rotate on its own axis due to the influence of the internal gear ring and the second gear.
