Description

Technical Field

[0001] The utility model relates to the technical field of winding, in particular to a winding device for carbon fiber manufacturing and processing. Background Art

[0002] In the manufacturing process of carbon fiber, winding is a crucial step. Traditional carbon fiber winding devices usually only focus on the basic winding function, ignoring the control of environmental conditions during the winding process and the impact on the winding quality. During the winding process, if the temperature and humidity cannot be effectively controlled, and dust pollutants in the environment cannot be removed, it may cause quality problems in the carbon fiber tow during winding.

[0003] During the winding process, tension control is one of the key factors that determine the quality of carbon fiber. Traditional winding devices often cannot achieve precise tension adjustment, resulting in the carbon fiber being easily relaxed or overstretched during winding.

[0004] Carbon fiber is very sensitive to environmental conditions (such as temperature, humidity, and cleanliness). Traditional winding devices lack effective environmental control measures and cannot guarantee constant temperature and humidity during the winding process, nor can they effectively remove dust and other pollutants in the environment.

[0005] Adjust the winding position or angle according to different process requirements, but the existing technology does not have the ability to flexibly adjust.

[0006] How to maintain constant tension during the winding process, especially during continuous winding, as the diameter of the coil gradually increases, how to dynamically adjust the tension to maintain uniformity is a problem that needs to be solved. Utility Model Content

The heating strip heats up and the air duct supplies air to jointly maintain the required temperature and humidity in the cabin, ensuring the stability of the winding environment. The following is a specific description of the solution through specific embodiments.

[0029] Reference Figures 1-6 A winding device for carbon fiber manufacturing and processing, comprising:

[0030] A base plate 1, a gearbox 2 and a clean cabin 31 mounted on the base plate 1, and a winding assembly mounted on one side of the gearbox 2 and cooperating with the clean cabin 31; the clean cabin 31 is connected to the bracket 3 by bolts; the inner wall of the clean cabin 31 is also provided with a heating strip for regulating the cabin temperature and an air duct for removing dust from the cabin.

[0031] The base plate 1 is provided with a bracket 3 for supporting the clean cabin 31 and a screw rod 5 for adjusting the bracket 3. The bracket 3 is sleeved on the screw rod 5 and meshes with the screw rod 5 for transmission. One end of the screw rod 5 is also provided with a first motor mounted on the base plate 1. The bracket 3 slides in cooperation with the groove 11 opened in the base plate 1. A positioning hole 313 and a feed port 311 are opened in the clean cabin 31. A guide wheel 312 is installed at the feed port 311; the positioning hole 313 and the transmission shaft 4 are located on the same axis, and the feed port 311 is opened on the outer surface of the clean cabin 31.

[0032] The winding assembly includes a transmission shaft 4 connected to the gearbox 2, and the transmission shaft 4 is clearance-fitted with the positioning hole 313. Two fixed plates 42 are sleeved on the transmission shaft 4, and movable plates 43 sleeved on the transmission shaft 4 are provided on both sides of one of the fixed plates 42. A connecting rod 44 passing through the fixed plate 42 is also provided between the two movable plates 43; the fixed plate 42 is interference-fitted with the transmission shaft 4, and the movable plate 43 is slidingly fitted with the transmission shaft 4.

[0033] A strut 46 movably connects the movable plate 43, the fixed plate 42 and the pull rod 45 in sequence, and a plurality of struts 46 are provided and evenly distributed on the outer surface of the movable plate 43. The gearbox 2 is also provided with a second motor for driving the transmission shaft 4; the two ends of the strut 46 are respectively movably connected to the pull rod 45 and the movable plate 43, and the strut 46 is provided with a through hole, and the through hole is movably connected to the fixed plate 42; a pull rod 45 is also provided between the two struts 46; a spring 47 and a baffle 41 are respectively sleeved on the two ends of the transmission shaft 4, and the spring 47 is clearance-fitted with the transmission shaft 4 and abuts against the movable plate 43, the baffle 41 is interference-fitted with the transmission shaft 4 and is a distance away from the fixed plate 42, and the baffle 41 is clearance-fitted with the clean cabin 31.

[0034] Working principle: First, the reel is inserted into the winding section. Then, the first motor drives the screw 5 to rotate, driving the bracket 3 to slide along the groove 11 on the bottom plate 1. The bracket 3 drives the clean cabin 31 to move toward the gearbox 2, thereby adjusting the distance between the clean cabin 31 and the winding section, so that the position of the clean cabin 31 and the winding assembly are matched.

[0035] During the movement of the clean cabin 31, the baffle 41 enters the clean cabin 31, and the positioning hole 313 cooperates with the transmission shaft 4 to insert the transmission shaft 4, and then the insertion depth is adjusted according to the length of the reel. During the insertion process, the spring 47 sleeved on the transmission shaft 4 will be squeezed, and the spring 47 will transmit the squeezing force it receives to the movable plate 43. At this time, the movable plate 43 moves on the transmission shaft 4 and approaches the fixed plate 42. The distance between the movable plate 43 and the fixed plate 42 changes, which changes the angle of the support rod 46, and then squeezes the reel sleeved on the pull rod 45 to make it firm. The connecting rod 44 connects the two movable plates 43 and runs synchronously. The feed port 311 guides the carbon fiber filaments to enter the clean cabin 31 smoothly for winding. The heating strips and air ducts are started to adjust the temperature in the cabin and remove dust in the cabin to provide a suitable winding environment. The carbon fiber filaments enter the clean cabin 31 through the guide wheel 312 and are evenly wound on the support part under the action of the winding assembly.

However, the present invention is not limited to the specific details in the above embodiments.
