Description

Technical Field

[0001] This utility model relates to the field of fiber production technology, specifically to a continuous feeding structure for short fiber processing. Background Technology

[0002] Staple fibers are a key basic material in industries such as textiles, nonwovens, and composites. Their production process encompasses core stages including raw material mixing, melt heating, extrusion molding, and subsequent processing. Among these, uniform mixing of raw materials is a crucial prerequisite for ensuring fiber quality, directly affecting the fiber's mechanical properties (such as strength and modulus), surface quality (such as gloss and roughness), and functional characteristics (such as flame retardancy and conductivity). However, traditional feeding devices often rely on manual or simple mechanical conveying, leading to the accumulation of raw materials at the feeding port or mixer inlet, forming localized high-concentration areas. This accumulation not only hinders the uniform dispersion of raw materials but may also cause agglomeration, making it difficult to achieve uniform mixing at the microscale in subsequent mixing stages.

[0003] The patented raw material feeding machine for polyester fiber production, disclosed in authorization announcement number CN219861702U, is equipped with stirring blades. This allows the motor housing to stir the raw materials inside the lower feed hopper via the stirring shaft. Furthermore, the insertion and engagement between the positioning tooth blocks and the positioning tooth grooves enables the motor housing to rotate the upper cover via the rotating stirring shaft, thereby achieving a sealing effect on multiple upper feed hoppers.

[0004] Although the aforementioned raw material feeding machine for polyester fiber production can feed different raw materials into the lower feeding hopper through multiple upper feeding hoppers at the top of the feeding barrel, there are still some shortcomings that warrant further optimization and improvement. For example, it fails to fully consider the material dispersion requirements, causing the same material to easily accumulate in the same place during feeding. This accumulation not only reduces mixing efficiency but also affects the uniform mixing of different raw materials.

[0005] Therefore, it is necessary to invent a continuous feeding structure for short fiber processing to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a continuous feeding structure for short fiber processing to solve the problems mentioned above.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a continuous feeding structure for short fiber processing, comprising a feeding base, a rotatable hopper inside the feeding base, a discharge port fixedly connected at the bottom opening of the hopper at an angle downwards, a transmission gear ring rotatably connected to the top of the feeding base, the hopper fixedly connected to the bottom of the transmission gear ring, a No. 1 motor mounted on the left side of the feeding base, a drive gear mounted on the top of the output shaft of the No. 1 motor, the drive gear meshing with the transmission gear ring, a controller mounted on the front of the feeding base, and the No. 1 motor electrically connected to the controller.

[0008] The drive gear is driven by motor number one to rotate, which in turn drives the transmission gear ring to rotate, and drives the material hopper to rotate around the central axis of the feeding base.

[0009] Preferably, the hopper has a hemispherical bowl-shaped structure, and the bottom opening of the hopper is located at the center.

[0010] The hemispherical bowl-shaped structure helps materials to quickly converge towards the discharge port within the hopper.

[0011] Preferably, the top of the feeding base has a first annular groove, inside which a ball is tumblingly arranged; the bottom of the transmission gear ring has a second annular groove, and the top of the ball extends to the outside of the first annular groove and tumblingly connects with the second annular groove.

[0012] The ball bearing design significantly reduces friction between the transmission gear ring and the feeding base, improving the smoothness of rotation.

[0013] Preferably, a fixed bracket is installed on the top of the feeding base, a storage box is installed in the middle of the fixed bracket, and a sealing cover is hinged to the top of the storage box.

[0014] The storage bin is used to store raw materials to be added. The sealed cover design effectively prevents dust and foreign objects from entering the storage bin, ensuring the cleanliness of the raw materials.

[0015] Preferably, a feeding hopper is fixedly connected to the bottom opening of the storage box, and a rotating shaft is rotatably connected inside the feeding hopper. Multiple feeding flaps arranged in a circular array are fixedly connected to the surface of the rotating shaft, and the gap between two adjacent feeding flaps matches the bottom opening of the feeding hopper.

[0016] By controlling the rotation speed of the feeding flap, the feeding speed and flow rate can be precisely controlled.

[0017] Preferably, a second motor is installed on the back of the hopper, one end of the rotating shaft extends to the outside of the hopper and is connected to the output shaft of the second motor for transmission, and the second motor is electrically connected to the controller.

[0018] By controlling the operation of motor No. 2 with a controller, the material feeding process is automated, improving production efficiency and stability.

[0019] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0020] 1. By designing the rotation mechanism of the feeding hopper, this utility model can ensure that the short fiber raw materials can be dispersed in all directions when added to the mixing container, avoiding local accumulation, thereby improving the mixing uniformity of the raw materials in the subsequent stirring process;

[0021] 2. By precisely controlling the rotation speed and frequency of the feeding flap and the rotation speed of the hopper, continuous and stable raw material feeding can be achieved. This continuous and stable feeding method helps to maintain the continuity and stability of the production process and improve production efficiency. Attached Figure Description

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0030] This utility model provides, for example Figure 1-5The continuous feeding structure for short fiber processing shown includes a feeding base 1, a hopper 2 rotatably disposed inside the feeding base 1, a discharge port 3 fixedly connected at an angle downward at the bottom opening of the hopper 2, a transmission gear ring 4 rotatably connected to the top of the feeding base 1, the hopper 2 fixedly connected to the bottom of the transmission gear ring 4, a first motor 5 installed on the left side of the feeding base 1, a drive gear 6 installed at the top of the output shaft of the first motor 5, the drive gear 6 meshing with the transmission gear ring 4, a controller 7 installed on the front of the feeding base 1, and the first motor 5 electrically connected to the controller 7.

[0031] In one aspect of this embodiment, the hopper 2 has a hemispherical bowl-shaped structure with its bottom opening at the center. A first annular groove 8 is formed on the top of the feeding base 1, and a ball bearing 9 is rolled inside the first annular groove 8. A second annular groove 10 is formed on the bottom of the transmission gear ring 4, and the top of the ball bearing 9 extends to the outside of the first annular groove 8 and is rolledly connected to the second annular groove 10. A fixed bracket 11 is installed on the top of the feeding base 1, and a storage box 12 is installed in the middle of the fixed bracket 11. The top of the storage box 12 is hinged. A sealing cover plate 13 is provided. A feeding hopper 14 is fixedly connected to the bottom opening of the storage box 12. A rotating shaft 15 is rotatably connected inside the feeding hopper 14. Multiple feeding flaps 16 arranged in a ring array are fixedly connected to the surface of the rotating shaft 15. The gap between two adjacent feeding flaps 16 matches the bottom opening of the feeding hopper 14. A second motor 17 is installed on the back of the feeding hopper 14. One end of the rotating shaft 15 extends to the outside of the feeding hopper 14 and is connected to the output shaft of the second motor 17. The second motor 17 is electrically connected to the controller 7.

[0032] The controller 7 mentioned above is an existing technology product, and its specific structure and functions will not be described in detail here.

[0033] Working principle of this utility model:

[0034] Refer to the instruction manual appendix Figure 1-5 When using this utility model, firstly, the entire device is set up at the top opening of the mixing container, and the short fiber raw material to be processed is placed into the storage box 12. The top of the storage box 12 is provided with a sealing cover plate 13, which can be closed when not in use to prevent dust and impurities from entering.

[0035] When it is necessary to add material into the mixing container, the No. 2 motor 17 is started, and its output shaft drives the rotating shaft 15 to rotate. Multiple feeding flaps 16 arranged in a ring array are fixed on the surface of the rotating shaft 15. As the rotating shaft 15 rotates, the feeding flaps 16 will open and close the bottom opening of the feeding hopper 14 in sequence, thereby controlling the feeding speed and flow rate of the raw materials. This process is controlled by the controller 7, which can adjust the speed of the No. 2 motor 17 according to production needs, thereby adjusting the feeding speed and flow rate.

[0036] The raw material falling from the feed hopper 14 enters the collection hopper 2. The collection hopper 2 is a hemispherical bowl-shaped structure with its bottom opening located in the center and a discharge port 3 fixedly connected at an angle downwards, which facilitates the guidance of the raw material to the discharge port 3 for collection.

[0037] At the same time, the No. 1 motor 5 is started, and the drive gear 6 at the top of its output shaft meshes with the transmission gear ring 4, driving the transmission gear ring 4 and the material collection hopper 2 fixed at its bottom to rotate around the central axis of the feeding base 1. During the rotation, the raw materials in the material collection hopper 2 are evenly discharged into the mixing container through the discharge port 3.

[0038] The top of the feeding base 1 has a first annular groove 8, inside which rolling balls 9 are rolled and connected to the second annular groove 10 at the bottom of the transmission gear ring 4, which reduces frictional resistance and improves the smoothness of rotation.
