Description

Technical Field

[0001] The utility model relates to the field of carbon fiber cloth processing, in particular to a carbon fiber cloth heating and drying machine. Background Art

[0002] After impregnation, carbon fiber cloth typically needs to be heated and dried in a specialized dryer to ensure stable performance and smooth subsequent processing. Dryers currently on the market typically consist of a sealed drying box with multiple layers of horizontal support nets designed to maximize space utilization, allowing users to stack and secure the carbon fiber cloth to be dried layer by layer. While this design significantly improves space utilization, it also presents several technical challenges that require urgent resolution:

[0003] Specifically, during the drying process of carbon fiber cloth, due to the increase in temperature, the chemicals inside or coated on the surface may undergo reactions such as pyrolysis and volatilization, thereby generating a certain amount of gas. To ensure the drying effect and the safety of the working environment, these gases must be quickly and effectively discharged from the drying box. However, the current multi-layer horizontal stacking layout to a certain extent hinders the natural rise of gas with the hot air flow, causing gas to accumulate between layers and difficult to quickly converge to the exhaust pipe at the top of the drying box. This reduces the gas emission efficiency, increases energy consumption during the drying process, and may affect the final drying quality of the carbon fiber cloth.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute prior art known to ordinary technicians in the field.

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0035] After the impregnation process, the carbon fiber cloth needs to be heated and dried in a dryer. Existing dryers primarily consist of a drying box with multiple layers of horizontal support nets, which are used to place the carbon fiber cloth to be dried layer by layer. While this facilitates placement of the carbon fiber cloth in the drying box, it also has some limitations: the carbon fiber cloth generates gases during the drying process, which need to be promptly discharged through the exhaust pipe at the top of the drying box. However, the layered arrangement of the carbon fiber cloth does not facilitate the upward flow of the gases with the hot air flow, reducing the efficiency of gas discharge.

[0036] In order to solve the above technical problems, this embodiment provides a carbon fiber cloth heating and drying machine, please refer to Figures 1 to 3 As shown, Figure 1 This is an exploded view of the carbon fiber cloth heating dryer in the embodiment. Figure 2 This is a front view of the carbon fiber cloth heating and drying machine in the embodiment. Figure 3 1 is a top view of a carbon fiber cloth heating and drying machine in an embodiment.

[0037] A carbon fiber cloth heating and drying machine according to this embodiment includes a drying box 1 , a carrier plate 2 , and a transfer table 3 .

[0038] The drying oven 1 has an inner chamber 11, which communicates with the exterior through an opening. A door 12 is provided at the opening to seal or open the inner chamber 11. An exhaust pipe 13 is mounted at the top of the inner chamber 11. The bottom and top of the inner chamber 11 are each provided with a plurality of pairs of slots 10 extending vertically and arranged on the same horizontal plane. One end of each pair of slots 10 extends to the opening. It will be appreciated that the drying oven 1 includes a heating device, such as an electric heater mounted on the bottom or side of the drying oven, to increase the temperature within the inner chamber 11.

[0039] The carrier plate 2 is used to fix the carbon fiber cloth. The carrier plate 2 can enter the two slots 10 of the same pair through the opening and be placed vertically in the drying box 1. There is a gap between each pair of slots 10 to form a vertically extending channel between the two adjacent carrier plates 2 and the carbon fiber cloth, and connected to the exhaust pipe 13.

[0040] The transfer table 3 is disposed at the front end of the opening and is provided with a table surface 31 . The table surface 31 is flush with the bottom of the inner cavity 11 and is used to support the carrier plate 2 .

[0041] The carbon fiber cloth heating and drying machine of the above technical solution fixes the carbon fiber cloth through the carrier plate 2. Subsequently, the carrier plate 2 can be placed on the table 31 of the transfer table 3 first, with the transfer table 3 as a support, and then conveniently pushed into the two pairs of card slots 10 from the opening, and placed vertically in the drying box 1, thereby improving the convenience of the carrier plate 2 and the carbon fiber cloth entering the drying box 1. After placing multiple carrier plates 2 in the above manner, due to the spacing between each pair of card slots 10, a vertically extending channel connected to the exhaust pipe 13 is formed between the adjacent two carrier plates 2 and the carbon fiber cloth. This channel can shorten the path of the gas generated during the drying process of the carbon fiber cloth to flow to the exhaust pipe 13. At the same time, the hot air flow has an upward trend, which can drive the gas to flow upward quickly, thereby increasing the efficiency of the gas discharged from the drying box 1. It can be seen that compared with the existing dryer, the carbon fiber cloth heating and drying machine of the above technical solution can improve the convenience of placing the carbon fiber cloth into the drying box 1 and improve the gas emission efficiency during the drying process.

[0042] Exemplarily, the drying box 1 is provided with a chamber on the top of the carrier plate 2 that is connected to the exhaust pipe 13 , and each channel formed between two adjacent carrier plates 2 and between the carbon fiber cloths is connected to the exhaust pipe 13 through the chamber.

[0043] In order to facilitate the insertion of the carrier board 2 from the table 31 into the card slot 10, refer to Figure 1 and Figure 3 As shown, the transfer table 3 is provided with a plurality of pairs of guide bars 32 on the table top 31, and guide openings 33 are formed between the same pair of guide bars 32. Each guide opening 33 is respectively arranged toward each card slot 10, and the diameter gradually decreases in the direction toward the card slot 10, and the whole presents a trapezoidal or trumpet-shaped shape. In this way, the bottom of the carrier board 2 can enter the card slot 10 from the guide opening 33, thereby improving the convenience of installing the carrier board 2.

[0044] Exemplarily, the guide bar 32 is integrally formed on the table top 31 .

[0045] Exemplarily, the transfer table 3 is placed on the ground and is fixed relative to the drying box 1 when in use.

[0046] In order to achieve that the carrier board 2 can be quickly aligned with the opening or guide opening 33 when entering the card slot 10 from the table 31, refer to Figure 1 、 Figure 4 and Figure 5 As shown, Figure 4 This is a three-dimensional diagram of the carrier board in the embodiment. Figure 5 This is a schematic diagram of the cooperation between the telescopic rod and the drying box in the embodiment. The carrier plate 2 includes a breathable mesh 21, a frame 22 and a telescopic rod 23. The frame 22 is fixed to the edge of the breathable mesh 21 by welding or clamping, and is provided with a sliding hole 200 extending in the direction of pushing into the card slot 10. The telescopic rod 23 is movably arranged in the sliding hole 200 to extend or retract relative to the frame 22; wherein, when the telescopic rod 23 extends out of the sliding hole 200, it is used to contact the inner wall of the inner cavity 11 or the carrier plate 2 in the inner cavity 11, so that the carrier plate 2 to be entered into the card slot 10 is positioned opposite to the card slot 10; when the carrier plate 2 fully enters the card slot 10, the telescopic rod 23 retracts or partially retracts into the sliding hole 200 due to the obstruction of the inner wall of the inner cavity 11. With such an arrangement, when the first carrier board 2 is placed, the carrier board 2 can contact the inner wall of the inner cavity 11 through the extended telescopic rod 23, so that the bottom end of the frame 22 is opposite to the guide port 33 or the opening position, that is, opposite to the position of the card slot 10. In this way, the operator can push the carrier board 2 into the card slot 10 more quickly, thereby improving the efficiency of the installation of the carrier board 2.

[0047] For example, see Figure 4 and Figure 5 As shown, the sliding hole 200 of the telescopic rod 23 is set on the cross bar 26 fixed to the top of the frame 22, and a limiting groove 260 for clamping the carbon fiber cloth is formed between the cross bar 26 and the breathable net 21.

[0048] Exemplarily, the breathable mesh 21 and the frame are square structures, and the telescopic rod 23 is spaced apart from the breathable mesh 21 so that the carbon fiber cloth can be placed on the breathable mesh 21 .

[0049] For example, see Figure 5 As shown, when the carrier plate 2 is completely inserted into the slot 10, the telescopic rod 23 is partially retracted into the slide hole 200 under the obstruction of the inner wall of the inner cavity 11; the inner wall of the inner cavity 11 is provided with a clearance hole 14, which is used to accommodate the telescopic rod 23 partially retracted into the slide hole 200. With this arrangement, when the carrier plate 2 is used to fix the carbon fiber cloth again, the extended part of the telescopic rod 23 facilitates the pulling out of the telescopic rod 23 from the slide hole 200, quickly preparing for the positioning required for the current installation of the carrier plate 2 and the carbon fiber cloth.

[0050] In one embodiment of fixing the carbon fiber cloth on the carrier plate 2, see Figure 4 As shown, a receiving groove 24 for receiving the carbon fiber cloth is formed between the frame 22 and the breathable mesh 21; the carrier plate 2 also includes a clip 25, which is rotatably connected to the frame 22 via a pin, and a damping structure is provided between the clip 25 and the frame 22. The damping structure, such as a rubber member, enables the clip 25 to maintain its position after rotation, so that when the clip 25 rotates into the receiving groove 24, the carbon fiber cloth is fixed between the clip 25 and the breathable mesh 21.

[0051] For example, see Figure 4 As shown, the clip 25 is provided with a fixing portion recessed into the receiving groove 24 , and the fixing portion is used to clamp the carbon fiber cloth with the breathable mesh 21 .

[0052] For example, see Figure 4 As shown, the edge of the clip 25 is provided with a curved surface, and an entrance 201 is formed between the curved surface and the breathable mesh 21. The diameter of the entrance 201 gradually increases toward the opening. The entrance 201 facilitates the clip 25 to be rotated from the side to the carbon fiber cloth, so that the carbon fiber cloth is fixed between the clip 25 and the breathable mesh 21.

[0053] In order to speed up the exhaust of gas in the inner cavity 11, refer to Figure 3 As shown, the drying box 1 further includes a fan 15 , which is disposed at the front end of the exhaust pipe 13 and fixed to the drying box 1 by bolts, and is used to guide the airflow in the inner cavity 11 to flow out from the exhaust pipe 13 .

[0054] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
