Description

Technical Field

[0001] This utility model relates to the field of carbon fiber filament bundle processing, and in particular to a sizing device for carbon fiber filament bundle processing. Background Technology

[0002] In recent years, the application of carbon fiber has developed rapidly and has been widely used in many fields such as aerospace, automobiles, energy, construction, and sports equipment. In the carbonization of carbon fiber, sizing is a very important process. The purpose of sizing is to give carbon fiber properties such as bundled properties, wear resistance, and water absorption resistance.

[0003] The prior art utility model patent with publication number CN 216006274 U discloses a sizing device for processing carbon fiber filament bundles. This sizing device for processing carbon fiber filament bundles increases the number of sizing rollers and extends the time when the carbon fiber filament bundles are immersed in the sizing solution, making it easier for the sizing solution to combine with the carbon fiber and improving the sizing efficiency. This utility model has the advantages of reasonable setting and low manufacturing cost.

[0004] However, it lacks the ability to space multiple sets of carbon fiber bundles. When sizing multiple sets of bundles simultaneously, problems such as bundle slippage and entanglement can easily occur, affecting processing safety and quality. In addition, it lacks the ability to filter and separate the device, and the debris carried by the bundles will fall directly into the box, making subsequent cleaning very troublesome. Therefore, we need to upgrade and modify the existing technology to overcome the existing problems and shortcomings. Utility Model Content

[0005] The purpose of this invention is to provide a sizing device for processing carbon fiber filament bundles, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] Design a sizing device for processing carbon fiber filament bundles, including a device body. The device body includes an outer shell, an inner shell, a limiting component, and a driving component. The inner wall of the outer shell is provided with a support frame. The lower end of the inner shell is inserted into the outer shell and the upper end is placed on the support frame. The lower end of the inner shell is provided with a filter hole. Two sets of upper guide rollers are symmetrically arranged at the upper end of the inner shell. Two sets of lower guide rollers are symmetrically arranged at the lower end of the inner shell. The limiting component is arranged on the lower guide rollers. The driving component is connected to the outside of the inner shell.

[0008] Furthermore, the limiting component includes a left chuck and a right chuck, the lower ends of the left chuck and the right chuck are respectively provided with a rotating groove and a rotating shaft, and the rotating shaft is inserted into the rotating groove.

[0009] Furthermore, the drive assembly includes a lifting cylinder, a collar is sleeved on the top of the lifting cylinder, and a connecting seat is fixed to the upper end of the collar.

[0010] Furthermore, the left and right chucks are provided with corresponding connecting holes at their upper ends, and fixing bolts are screwed into the connecting holes. The left and right chucks are symmetrically sleeved on the lower guide roller.

[0011] Furthermore, two sets of lifting cylinders are symmetrically arranged and located on the outer side of the outer shell, and the connecting seat is fixed on the side wall of the inner shell.

[0012] Furthermore, two sets of handles are symmetrically arranged at the upper end of the inner shell, two sets of brush rollers are provided at the lower end of the inner shell, and a scraper box is provided on one side of the inner wall of the inner shell.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1 As shown in Figure 5, this embodiment provides a sizing device for processing carbon fiber filament bundles, including a device body 1. The device body 1 includes an outer shell 2, an inner shell 3, a limiting component 6, and a driving component 7. The inner wall of the outer shell 2 is provided with a support frame 21. The lower end of the inner shell 3 is inserted into the outer shell 2 and the upper end is placed on the support frame 21. The lower end of the inner shell 3 is provided with a filter hole 31. Two sets of upper guide rollers 4 are symmetrically arranged on the upper end of the inner shell 3. Two sets of lower guide rollers 5 are symmetrically arranged on the lower end of the inner shell 3. The limiting component 6 is arranged on the lower guide rollers 5. The driving component 7 is connected to the outside of the inner shell 3. Two sets of handles 32 are symmetrically arranged on the upper end of the inner shell 3. Two sets of brush rollers 9 are provided on the lower end of the inner shell 3. A scraper box 8 is provided on one side of the inner wall of the inner shell 3. The handles 32 facilitate the lifting and placing of the inner shell 3. The brush rollers 9 facilitate the brushing of the carbon fiber filament bundles, improving the sizing quality and uniformity. The scraper box 8 facilitates the scraping of excess sizing material on the surface of the carbon fiber filament bundles.

[0026] Preferably, the limiting assembly 6 includes a left chuck 61 and a right chuck 62. The lower ends of the left chuck 61 and the right chuck 62 are respectively provided with a rotating groove 63 and a rotating shaft 64, and the rotating shaft 64 is inserted into the rotating groove 63. The upper ends of the left chuck 61 and the right chuck 62 are respectively provided with connecting holes 65, and fixing bolts 66 are screwed into the connecting holes 65. The left chuck 61 and the right chuck 62 are symmetrically sleeved on the lower guide roller 5.

[0027] The left chuck 61 and the right chuck 62 are rotatably connected by the rotating groove 63 and the rotating shaft 64. The left chuck 61 and the right chuck 62 are rotatably sleeved on the outside of the lower guide roller 5 and fixedly connected by the connecting hole 65 and the fixing bolt 66. This enables convenient disassembly and assembly of the limiting component 6, facilitates the division of the lower guide roller 5 into multiple independent areas, facilitates the blocking of multiple groups of carbon fiber bundles, prevents contact entanglement, and improves the practicality of the device.

[0028] Preferably, the drive assembly 7 includes a lifting cylinder 71, a collar 72 is sleeved on the top of the lifting cylinder 71, a connecting seat 73 is fixed at the upper end of the collar 72, two sets of lifting cylinders 71 are symmetrically arranged and located on the outside of the outer shell 2, and the connecting seat 73 is fixed on the side wall of the inner shell 3.

[0029] The lifting cylinder 71 drives the collar 72 and the connecting seat 73 to rise and fall. The connecting seat 73 moves the inner shell 3 to rise and fall, which can separate the inner shell 3 from the outer shell 2. This makes it easy to remove the inner shell 3 from the outer shell 2, thereby separating the fiber debris from the slurry, facilitating the cleaning of the inside of the device, and improving the practicality of the device.

[0030] The working principle and process of this utility model are as follows: First, the limiting component 6 is installed on the lower guide roller 5. The left chuck 61 and right chuck 62 are rotatably connected via the rotating groove 63 and rotating shaft 64. The left chuck 61 and right chuck 62 are rotatably sleeved on the outside of the lower guide roller 5 and fixedly connected via the connecting hole 65 and fixing bolt 66. Install an appropriate number of limiting components 6 as needed and adjust the appropriate spacing. Then, the carbon fiber bundle can pass through the upper end of one side of the upper guide roller 4, and then sequentially pass through the lower ends of the two sets of lower guide rollers 5. The material passes through the scraper box 8 and exits from the upper end of the guide roller 4 on the other side, completing the sizing operation of the carbon fiber tow. When it is necessary to replace or clean the slurry inside the equipment, the lifting cylinder 71 can be driven to work. The lifting cylinder 71 drives the collar 72 and the connecting seat 73 to rise and fall. The connecting seat 73 carries the inner shell 3 to rise until the inner shell 3 is completely separated from the outer shell 2. At this time, the inner shell 3 can be lifted and removed by the handle 32. During this process, the filter hole 31 can separate the fiber debris from the slurry, preventing the fiber and slurry from mixing and becoming difficult to clean.
