Description

Technical Field

[0001] This utility model relates to a fiber blowing device. Background Technology

[0002] Before processing, the various fiber materials in the polymer fiberboard need to be uniformly mixed in a blending machine, and then conveyed through ducts to a cotton spinning machine for weaving into polymer fiber fabric. The ducts use air power to blow the mixed fibers, but the amount of fiber is uneven during the blowing process, resulting in an uneven amount delivered to the cotton spinning machine. When the amount of fiber delivered to the duct increases, the fiber may clog the duct due to insufficient airflow from the blower. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, this utility model provides a fiber blowing device that can ensure the uniform delivery of fiber materials.

[0004] To achieve this objective, the structure adopted in this utility model is as follows: a fiber blowing device, including a conveyor box and an air duct. A conveyor belt is installed inside the conveyor box, and L-shaped hooks are provided on the surface of the conveyor belt. The opening of the L-shaped hooks faces the forward direction of the conveyor belt. The outlet of the conveyor box is connected to the air duct, and the air duct is connected to a fan. A rotating shaft is provided at the center of the bottom of the air duct. The rotating shaft is connected to a motor, and support rods are arranged on the surface of the rotating shaft. The support rods can contact the conveyor belt.

[0005] The end of the support rod that contacts the conveyor belt is a flexible plastic rod or a rubber rod.

[0006] A bend is provided in the center of the air duct. The bend has an S-shaped filling structure and an observation window at the top. The observation window can be opened.

[0007] Its beneficial effects are: the structure of this utility model is reasonable and ingenious. The rotating shaft with support rods picks down the fibers on the conveyor belt in batches and evenly, and the wind blown by the fan moves along the air duct. When the fan suddenly stops, the fibers in the air duct fall and accumulate at the bend. The rotating shaft stops, and there are no fibers accumulating at the bottom of the air duct. The accumulated fibers can be treated at the through-window to clean the pipe. Attached Figure Description

[0008] This utility model will be described by way of example and with reference to the accompanying drawings, wherein:

[0009] Figure 1 This is the front view of this utility model. Detailed Implementation

[0010] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0011] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0012] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components; a fixed connection can be welding or adhesive bonding. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0013] like Figure 1 The fiber blowing device shown includes a conveyor box 1 and an air duct 4. The conveyor box 1 is a box connected to the outlet of the cotton blending machine. A conveyor belt 2 is installed inside the conveyor box 1. The conveyor belt 2 is rotated by a rotating roller. L-shaped hooks 3 are evenly arranged on the surface of the conveyor belt 2. One end of the L-shaped hook 3 is connected to the conveyor belt 2, and the other end forms an opening with the conveyor belt, facing the direction of the conveyor belt 2's movement. During rotation, the L-shaped hooks 3 hook the fibers at the outlet of the cotton blending machine and convey them to the air duct. The air duct 4 is connected to a blower 7. A rotating shaft 5 is installed at the center of the bottom of the air duct 4. The rotating shaft 5 is driven by a motor. Multiple support rods 6 are arranged on the surface of the rotating shaft 5. The ends of the support rods 6 contact the conveyor belt 2. During rotation, they pick up the fibers on the conveyor belt 2. The end of the support rod 6 that contacts the conveyor belt is a flexible rubber rod or plastic rod, which ensures that the fibers are picked up while avoiding scratches on the conveyor belt.

[0014] The middle section of the air duct 4 is equipped with a bend pipe 8, which is S-shaped. The top of the bend pipe 8 is equipped with an observation window 9, which can be opened. When the fan stops working, the fibers that have lost power fall and accumulate at the bend pipe, and can be cleaned through the observation window 9.

[0015] An airflow detection head is installed inside the duct. The airflow detection head is connected to a PLC. The PLC controls the operation of the shaft motor and the conveyor belt motor. When the airflow detection head detects insufficient airflow in the duct, the PLC controls the shaft motor and the conveyor belt motor to stop rotating to prevent fiber accumulation at the lower end of the duct.

[0016] Based on the above description and inspired by this utility model, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
