Description

Technical Field

[0001] The utility model relates to the technical field of carbon fiber processing equipment, in particular to a carbon fiber yarn spreading and blowing device. Background Art

[0002] Carbon fiber refers to high-strength and high-modulus fiber with a carbon content of more than 90%. It ranks first among all chemical fibers in terms of high temperature resistance. It is made of acrylic and viscose fibers as raw materials and oxidized and carbonized at high temperature. It is an excellent material for manufacturing high-tech equipment such as aerospace. Carbon fiber products usually use a braiding machine to weave multiple carbon fiber bundles into carbon fiber cloth, and then process various products. In the process of weaving the carbon fiber bundles with a braiding machine, the carbon fiber bundles are transported from the spool to the braiding machine. During the transportation of the carbon fiber bundles to the braiding machine, static electricity will be generated due to the mutual friction between the carbon fiber bundles. Static electricity will absorb carbon fiber burrs in the air, as well as dust, particles and other impurities in the air. The impurities stick to the carbon fiber bundles and are woven into the carbon fiber cloth by the braiding machine, resulting in a variety of impurities on the carbon fiber cloth, which reduces the quality of the product. In view of this, overcoming the defects of the above-mentioned prior art is a problem to be solved in this technical field. Utility Model Content

[0028] Example

[0029] See also Figure 1 and Figure 2 The utility model provides a carbon fiber yarn blowing device, including a support frame 100, on which a translation mechanism 200 is installed. Any translation mechanism 200 that can realize the back and forth movement of the blowing mechanism below on the support frame 100 is acceptable, and is preferably composed of a servo motor, a synchronous wheel and a synchronous belt (not shown in the figure). The mounting seat 310 of the blowing mechanism 300 is fixed on the synchronous belt, and the synchronous belt moves back and forth repeatedly, driving the mounting seat 310 to move back and forth on the support frame 100, thereby realizing all-round blowing of the carbon fiber bundle passing through the support frame 100, ensuring thorough and clean removal of impurities.

[0030] See also Figure 2 and Figure 3The translation mechanism 200 is provided with a blowing mechanism 300, and the blowing mechanism 300 includes a mounting seat 310, and the mounting seat 310 is fixed on the moving unit of the translation mechanism 200. The translation mechanism 200 can drive the mounting seat 310 to move back and forth on the support frame 100. The mounting seat 310 is provided with an air pipe joint 320, and the air pipe joint 320 is preferably a three-way joint. Specifically, the inlet of the air pipe joint 320 is connected with an air intake pipe 330, and the air intake pipe 330 is connected with a high-pressure air pump. The two outlets of the air pipe joint 320 are both connected with an air delivery pipe 340, and the ends of the air delivery pipe 340 are connected with a connecting seat 350. The two connecting seats 350 are fixedly installed on both sides of the lower end of the mounting seat 310 by welding, and the lower side of the connecting seat 350 is equidistantly provided with A plurality of air outlet heads 360 are provided, and the air outlet heads 360 are arranged downward. The carbon fiber bundle to be woven passes through the bottom of the air outlet heads 360, and the gas blown out by the air outlet heads 360 is blown toward the carbon fiber bundle, so as to blow the debris stuck on the carbon fiber bundle away from the carbon fiber bundle. Preferably, a return air pipe 370 is connected to the front and rear ends of the connecting seat 350, and the return air pipe 370 is connected to the air outlet heads 360. When the other part of the high-pressure gas flows from one end of the connecting seat 350 through the return air pipe 370 to the other end of the connecting seat 350, and then flows out from the air outlet heads 360, it is avoided that the air pressure in the connecting seat 350 is too high, resulting in the air supply pipe 340 and the air outlet heads 360 being separated from the connecting seat 350 under the pressure of the high-pressure gas, thereby reducing the air pressure and relieving the airflow.

[0031] In addition, a plurality of translation mechanisms 200 and blowing mechanisms 300 are installed at certain intervals on the support frame 100 for transporting the carbon fiber bundle. It is necessary to set up a plurality of translation mechanisms 200 and blowing mechanisms 300. The plurality of translation mechanisms 200 and blowing mechanisms 300 are used to blow the carbon fiber bundles at different positions, so that the carbon fiber bundles are blown multiple times during the process of running to the braiding machine, and the impurities in the carbon fiber bundles are removed more thoroughly and cleanly.

[0032] See also Figure 4 , Figure 5 , Figure 6 and Figure 7 It should be noted that a storage mechanism 400 is provided below the air outlet head 360, and the storage mechanism 400 includes a storage box 410 with an opening at the top, and the storage box 410 is used to store impurities blown down from the carbon fiber harness, and plug-in ports 411 are symmetrically provided on the front and rear box walls of the storage box 410, and a guide plate 420 is plugged into the plug-in port 411, and the length of the guide plate 420 is not shorter than the length of the storage box 410. In this way, after the guide plate 420 is inserted into the plug-in ports 411 on the front and rear walls of the storage box 410, the guide plate 420 crosses the inner cavity of the entire storage box 410, and the guide plate 420 is tilted downward in the storage box 410, and the impurities blown down from the carbon fiber harness are blown to the bottom end (such as Figure 7 As shown), preferably, a limit plate 421 is fixed at one end of the guide plate 420, and the limit plate 421 is arranged on the outside of the storage box 410. When the guide plate 420 is inserted into the storage box 410, the limit plate 421 contacts the outer wall of the storage box 410 and stops moving forward. At this time, the front end of the guide plate 420 passes through the rear wall of the storage box 410, and then the box wall of the storage box 410 supports and fixes the guide plate 420. The limit plate 421 plays a role of limiting and protecting. At least two guide plates 420 are provided, and at least two guide plates 420 are staggered inside the storage box 410 (as shown in FIG. Figure 7 As shown in the figure, at least two guide plates 420 are symmetrically arranged in the storage box 410, and the guide plates 420 are inclined so that the impurities blown into the storage box 410 flow forward along the direction of the guide plates 420 with the high-pressure airflow, and at the same time greatly reduce the flow speed of the airflow, thereby preventing the impurities from being driven by the high-pressure airflow and being reacted by the wall of the storage box 410 and returning to the opening of the storage box 410, thereby preventing the impurities from splashing back out of the storage box 410.

[0033] It should be noted that the motion state and motion trajectory of each mechanism of the device can be automatically controlled by numerical control programs or PLC programming, and automatic start and stop and automatic operation can be achieved in conjunction with position switches. The above-mentioned programs and programming are common knowledge known to those skilled in the art, so they will not be described in detail here;

[0034] The specific model and specifications of the translation mechanism 200 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0035] The power supply and principle of the translation mechanism 200 are clear to those skilled in the art and will not be described in detail here.

[0036] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
