Description

Technical Field

[0001] This utility model relates to the field of carbon fiber production technology, specifically to a slurry mixing device for carbon fiber sizing. Background Technology

[0002] In the field of carbon fiber production technology, carbon fiber sizing is one of the key steps. The sizing process can significantly improve the surface properties of carbon fiber, enhance the interfacial bonding force between it and the resin matrix, and thus improve the overall mechanical properties of composite materials, such as tensile strength, flexural strength and interlaminar shear strength.

[0003] Existing mixing methods are relatively simple, usually relying solely on fixed-position stirring blades for mixing. This limits the mixing range and makes it difficult to achieve a comprehensive and uniform mixture of slurry within the tank. Consequently, the sizing agent and water are not fully mixed, resulting in low mixing efficiency. Existing feeding methods are mostly point-to-point feeding, causing the sizing agent to concentrate in a certain area after being injected into the tank, further exacerbating the problem of uneven mixing. This results in some areas having excessively high sizing agent concentrations while others have excessively low concentrations, failing to meet the uniformity requirements of carbon fiber sizing. Utility Model Content

[0004] To address this issue, this invention provides a slurry mixing device for carbon fiber sizing, which solves the problem of relatively simple stirring methods. Typically, stirring is carried out using only fixed-position stirring blades, resulting in a limited stirring range and difficulty in achieving a comprehensive and uniform mixture of slurry and water within the tank. This leads to insufficient mixing of the sizing agent and water, resulting in low mixing efficiency. Existing feeding methods are mostly fixed-point feeding, where the sizing agent is concentrated in a certain area after being injected into the tank, further exacerbating the problem of uneven mixing. This results in some areas having excessively high sizing agent concentrations while others have excessively low concentrations, failing to meet the uniformity requirements of carbon fiber sizing.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a slurry mixing device for carbon fiber sizing, comprising a tank, wherein a mixing mechanism is provided inside the tank; The mixing mechanism includes a first motor, which is fixedly mounted at the bottom of the tank. A rotating rod is fixedly connected to the output end of the first motor. The rotating rod extends into the tank and is connected to the tank via a bearing. Multiple second stirring blades are fixedly connected to the outside of the rotating rod. Multiple first stirring blades are also fixedly connected to the outside of the rotating rod. A connecting shell is fixedly connected to one end of the rotating rod. A round tube is fixedly mounted on the top of the connecting shell. The round tube passes through the top of the tank and is connected to the tank via a bearing. A threaded rod is connected to the inside of the connecting shell via a bearing. A second bevel gear is fixedly fitted on the outside of the threaded rod. The threads on both sides of the threaded rod have opposite directions. Sliding blocks are threaded on both sides of the threaded rod. A connecting rod is fixedly mounted at the bottom of the sliding blocks. Multiple third stirring blades are fixedly mounted on one side of the connecting rod.

[0006] Preferably, a circular plate is fixedly provided at the top of the circular tube, a second motor is fixedly connected to the output end of the circular plate, a transmission shaft is fixedly connected to the output end of the second motor, the transmission shaft passes through the connecting shell and is connected to the connecting shell through a bearing, a first bevel gear is fixedly connected to one end of the transmission shaft, and the first bevel gear meshes with the second bevel gear.

[0007] Preferably, the mixing mechanism includes a feeding assembly, which includes a material shell fixedly disposed inside the tank. A feeding pipe is connected to one side of the material shell, and a rotating plate is connected to the bottom of the material shell through a sealed bearing. Two conveying pipes are fixedly connected to one side of the rotating plate, and one end of each of the two conveying pipes is fixedly connected to a connecting rod. A material cavity is opened inside the connecting rod, and the conveying pipes communicate with the material cavity. A feeding head is fixedly connected to one side of the connecting rod.

[0008] Preferably, a plurality of fixing rods are fixed between the rotating plate and the connecting shell.

[0009] Preferably, a sliding rod is fixedly provided on both sides of the rotating rod, and a sliding sleeve is sleeved on the outside of the sliding rod. The sliding sleeve slides outside the sliding rod, and multiple pulleys are connected inside the sliding sleeve through bearings. The pulleys are in contact with the sliding rod, and the sliding sleeve is fixedly connected to the connecting rod.

[0010] Preferably, a heating sleeve is fixedly fitted on the outside of the tank.

[0011] Preferably, a feed pipe is fixedly provided on the top of the tank.

[0012] Preferably, a discharge pipe is fixedly provided at the bottom of the tank.

[0013] Preferably, the bottom of the tank is fixedly provided with multiple support columns.

[0014] The present invention has the following advantages: The first motor drives the rotating rod to rotate, causing the first stirring blade, the second stirring blade, and the connecting rod to rotate synchronously, thus achieving initial stirring of the slurry in the tank. At the same time, the second motor drives the threaded rod to rotate, causing the sliding block to move, which in turn causes the connecting rod and the third stirring blade to move horizontally while rotating, expanding the stirring range and forming a multi-dimensional stirring mode. This allows for more thorough mixing of the slurry, greatly improving the mixing efficiency and effectively solving the problems of limited stirring range and insufficient mixing in traditional devices. The design of the feeding assembly allows the sizing agent to enter the material shell through the feeding pipe, and then be fed through the conveying pipe, material chamber and feeding head. With the rotation of the connecting rod, the sizing agent is fed in a rotary manner. This feeding method allows the sizing agent to be injected into the tank at multiple points, avoiding the problem of excessively high local concentration caused by fixed-point feeding. It allows the sizing agent to be distributed more evenly in the water, further improving the mixing uniformity of the slurry and providing a stable slurry for carbon fiber sizing.
