Description

Technical Field

[0001] This utility model relates to the field of carbon fiber cloth processing technology, specifically a pre-impregnation device for carbon fiber cloth processing. Background Technology

[0002] Traditional carbon fiber cloth processing methods have many shortcomings in the impregnation process. Early manual impregnation methods involved operators immersing each piece of carbon fiber cloth into impregnation solutions such as resin. This method was not only inefficient, but also made it difficult to ensure the uniformity of impregnation for each piece of carbon fiber cloth, resulting in inconsistent product quality and failing to meet the requirements of large-scale industrial production for product consistency and high quality.

[0003] Furthermore, the treatment of excess impregnation liquid on the impregnated carbon fiber cloth is not precise enough. Some devices only use simple natural dripping or rough squeezing to remove excess impregnation liquid, which cannot accurately control the adhesive content of the carbon fiber cloth. Inaccurate adhesive content will have an adverse effect on the curing process and final performance of the carbon fiber composite material. For example, too high adhesive content may lead to a decrease in the strength and an increase in the weight of the composite material, while too low adhesive content will affect its interlayer bonding.

[0004] For example, the existing Chinese patent with publication number CN221895337U discloses a pre-impregnation device for processing carbon fiber cloth. Because the device does not have a corresponding structure for removing excess impregnation liquid, a large amount of resin adheres to the surface of the carbon fiber cloth after impregnation, which affects subsequent processing steps.

[0005] Therefore, a pre-impregnation device for carbon fiber cloth processing is needed. Utility Model Content

[0006] The purpose of this invention is to provide a pre-impregnation device for carbon fiber cloth processing. By using this device, the problem of a large amount of resin adhering to the surface of the carbon fiber cloth after impregnation is solved, which affects subsequent processing steps.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a pre-impregnation device for carbon fiber cloth processing, comprising an impregnation tank, with a winding structure at both ends of the impregnation tank, a material stop at one end of the winding structure, and a recovery mechanism fixedly installed inside the impregnation tank. The recovery mechanism includes a lower scraper and connecting plates 1 fixedly connected to both sides of the lower scraper. The connecting plates 1 are fixedly connected to the inner wall surface of the impregnation tank. An upper scraper is provided above the lower scraper, and connecting plates 2 are fixedly installed on both sides of the upper scraper. The connecting plates 2 are slidably connected to the inner wall surface of the impregnation tank. A threaded rod is threadedly installed inside the connecting plate 2 located on one side of the upper scraper, and the threaded rod is connected to the lower scraper. A connecting plate on one side is rotatably connected and passes through the threaded rod. A rotating handle is fixedly installed at the upper end of the threaded rod. A sliding rod is slidably installed inside the connecting plate on the other side of the upper scraper. The sliding rod is fixedly connected to the connecting plate on the other side of the lower scraper. After the carbon fiber cloth is impregnated, it is squeezed by the lower and upper scrapers to remove excess resin, thus facilitating subsequent processing operations. At the same time, according to the needs of use, the threaded rod can be rotated by turning the rotating handle, which in turn drives the connecting plate to move the upper scraper vertically up and down, realizing the adjustment of the distance between the lower and upper scrapers, greatly improving its application range and enhancing its practicality.

[0008] Preferably, the lower end of the connecting plate is provided with an elastic element, which includes a fixed plate fixedly connected to the inner wall surface of the immersion tank. A telescopic rod is fixedly installed on the upper end of the fixed plate, and an insert block is fixedly installed on the upper end of the telescopic rod. A lever block is fixedly installed on one side of the insert block. A spring is sleeved on the outer side of the telescopic rod. The upper end of the spring is fixedly connected to the insert block, and the lower end of the spring is fixedly connected to the fixed plate. In the initial state, the insert block is inserted into the lower end of the threaded rod, effectively preventing it from rotating. When adjustment is required, the lever block is moved to drive the insert block to squeeze the spring, so that the insert block leaves the inside of the threaded rod. After adjustment, the lever block is released, the spring resets, and pushes the insert block to re-insert into the inside of the threaded rod, achieving quick fixation.

[0009] Preferably, the winding structure includes a connecting rod fixedly connected to the impregnation tank. A rotating shaft is rotatably mounted on the upper end of the connecting rod. A servo motor is fixedly mounted on one end of the rotating shaft. A fixing component fixedly connected to the connecting rod is fixedly mounted on the outside of the servo motor. A winding roller is fixedly mounted on the outside of the rotating shaft. This allows one end of the carbon fiber cloth to be fixed by the winding roller. Then, the servo motor is started to drive the rotating shaft to rotate, thereby driving the winding roller to rotate. Since there are two sets of winding structures located on both sides of the impregnation tank, the carbon fiber cloth passes through the impregnation tank at a uniform speed to complete the impregnation process.

[0010] Preferably, the material stop includes a material stop rod and fixed rods located on both sides and fixedly connected thereto. A connecting block is rotatably mounted on the end of the fixed rod away from the material stop rod and fixedly connected to the other end of the rotating shaft. A torsion spring is sleeved on the outside of the fixed rod. One end of the torsion spring is fixedly connected to the material stop rod, and the other end of the torsion spring is fixedly connected to the connecting block. Due to the setting of the torsion spring, the material stop rod is initially in a vertical state, thereby preventing the carbon fiber cloth from detaching from the winding roller during the winding process, thus preventing processing accidents. When unloading, the material stop rod is rotated around the fixed rod as the axis until it reaches a horizontal state.

[0011] Preferably, the impregnation chamber is equipped with two sets of leveling rollers and multiple sets of impregnation rollers. The two sets of leveling rollers are used to level the carbon fiber cloth entering the impregnation chamber in advance to prevent wrinkles and ensure the subsequent impregnation effect. The multiple sets of impregnation rollers cause the carbon fiber cloth to bend continuously during the impregnation process, thereby realizing the repeated absorption and extrusion of resin by the carbon fiber cloth and achieving efficient impregnation.

[0012] Preferably, the outer surface of the impregnation tank is provided with a window, and an addition tube is fixedly installed at the upper end of the impregnation tank. The opening of the window facilitates quick observation by personnel, while the addition tube facilitates quick addition of resin by personnel.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This utility model proposes a pre-impregnation device for carbon fiber cloth processing. After the carbon fiber cloth is impregnated, it is squeezed by the lower scraper and the upper scraper to remove excess resin, thereby facilitating subsequent processing operations. At the same time, according to the needs of use, the screw rod can be rotated by turning the handle, which in turn drives the connecting plate to move the upper scraper vertically up and down, thereby adjusting the distance between the lower scraper and the upper scraper, greatly improving its application range and enhancing its practicality.

After the carbon fiber cloth is impregnated, it is squeezed by the lower scraper 141 and the upper scraper 142 to remove excess resin, which facilitates subsequent processing operations. At the same time, according to the needs of use, the threaded rod 146 can be rotated by turning the rotating handle 147, which in turn drives the connecting plate 144 to move the upper scraper 142 vertically up and down, so as to adjust the distance between the lower scraper 141 and the upper scraper 142, greatly improving its application range and enhancing its practicality.

[0026] Combination Figure 7 The lower end of the connecting plate 143 is provided with an elastic element 145.

In the initial state, the insert 1453 is inserted into the lower end of the threaded rod 146, effectively preventing it from rotating. When adjustment is required, the insert 1453 is pushed by the toggle block 1454 to squeeze the spring 1455, so that the insert 1453 leaves the inside of the threaded rod 146. After the adjustment is completed, the toggle block 1454 is released, the spring 1455 is reset and pushes the insert 1453 to re-insert into the inside of the threaded rod 146, so as to achieve quick fixation.

This allows one end of the carbon fiber cloth to be fixed by the winding roller 23. Then, the servo motor 24 is started to drive the rotating shaft 22 to rotate, thereby driving the winding roller 23 to rotate. Since the winding structure 2 is provided with two sets and located on both sides of the impregnation tank 1, the carbon fiber cloth passes through the impregnation tank 1 at a uniform speed to complete the impregnation process.

Due to the setting of the torsion spring 34, the material stop rod 31 is initially in a vertical state, thereby preventing the carbon fiber cloth from detaching from the winding roller 23 during the winding process, thus preventing processing accidents. When unloading, the material stop rod 31 is rotated around the fixed rod 32 as the axis until it is in a horizontal state.

[0029] Combination Figure 3 The impregnation chamber 1 is equipped with two sets of leveling rollers 13 and multiple sets of impregnation rollers 15. The two sets of leveling rollers 13 are used to level the carbon fiber cloth entering the impregnation chamber 1 in advance to prevent it from wrinkling, so as to ensure the subsequent impregnation effect. The multiple sets of impregnation rollers 15 are used to make the carbon fiber cloth bend continuously during the impregnation process, thereby realizing the repeated absorption and extrusion of resin by the carbon fiber cloth and achieving efficient impregnation.
