Description

Technical Field

[0001] This utility model relates to the field of warping machine technology, and in particular to a carbon fiber spreading and warping machine. Background Technology

[0002] A carbon fiber spreading and warping machine is a type of warping machine that evenly spreads multiple bundles of untwisted filaments into sheet yarns of a certain weight, and then winds them onto a warping head at a constant speed and tension.

[0003] The general principle of a carbon fiber warping machine is as follows: the fiber is passively or actively unwound from the wound yarn bobbin (several yarn bobbins wound with carbon fiber yarn are installed on the yarn frame), passes through the guide tube and the yarn separating reed into the ordinary guiding device, and then enters the vibrating and heating fiber spreading area (high frequency vibrating and heating). After spreading, it enters the tensioning area and is finally wound onto the warp head at a uniform speed and constant tension.

[0004] In existing warping machines, the heating tube surface is prone to wear due to long-term friction with the yarn, and the yarn tends to accumulate on the surface of the fixed heating tube, resulting in decreased heat transfer efficiency and unstable yarn quality. When manually adjusting the height of the heating tube, the position of the waist hole needs to be repeatedly calibrated, which is cumbersome and makes it difficult to ensure the parallelism of the heating roller, affecting the uniformity of fiber spreading. During the processing, the yarn fuzz and waste fall directly and accumulate, requiring frequent machine stops for cleaning, which affects production efficiency and environmental cleanliness. Utility Model Content

[0005] The technical problem to be solved by this utility model is: in order to overcome the problems in the prior art where the heating tube surface of the warping machine is easily worn due to long-term friction with the yarn, and the yarn is easy to accumulate on the surface of the fixed heating tube, resulting in a decrease in heat transfer efficiency and unstable yarn quality, and the need to repeatedly calibrate the waist hole position when manually adjusting the height of the heating tube, which is cumbersome and makes it difficult to ensure the parallelism of the heating roller, thus affecting the uniformity of fiber spreading, a carbon fiber spreading warping machine is provided.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a carbon fiber spreading and warping machine, including a frame and a spreading mechanism arranged on the frame. The spreading mechanism includes a mounting base, a lifting drive and a spreading assembly. The output end of the lifting drive is connected to the mounting base. The lifting drive provides power for the lifting of the spreading assembly. The spreading assembly is arranged on the mounting base. The spreading assembly is used to evenly spread multiple bundles of untwisted filament raw materials into sheet yarn. By driving the heating roller to rotate actively, the yarn is made to contact the roller surface evenly, avoiding local wear and ensuring the parallelism of the heating roller.

[0007] To address the lack of dynamic fiber spreading capability in the fiber spreading mechanism and the problem of yarn accumulation on the fixed heating roller, the fiber spreading assembly further includes a vibrating roller, a vibrating drive, a heating roller, and a roller drive. The vibrating drive is fixedly connected to the frame, the output end of the vibrating drive is drivenly connected to the vibrating roller, the vibrating roller is located between the heating rollers, the heating roller is rotatably connected to the mounting base, and the output end of the roller drive is drivenly connected to the input end of the heating roller.

[0008] To address the issue of localized overheating and wear caused by fixing the heating roller, the heating roller further includes a hollow roller body and a heating tube, with the heating tube located inside the roller body. The heating tube is fixedly connected to the mounting base, while the roller body and the mounting base are rotatably connected.

[0009] It further includes a lifting drive component for use as an elevator.

[0010] To address the issue of waste accumulation affecting the production environment, the warping machine further includes a cleaning mechanism located below the fiber spreading mechanism. The cleaning mechanism is used to collect carbon fiber fuzz, waste filaments, and other impurities and waste falling from the fiber spreading mechanism.

[0011] The cleaning mechanism includes a conveyor belt and a waste trough. The conveyor belt is fixedly connected to the frame, the waste trough is fixedly connected to the frame, and the waste trough is connected to the output end of the conveyor belt.

[0012] The beneficial effects of this utility model are as follows: The carbon fiber spreading and warping machine provided by this utility model drives the heating roller to rotate actively, so that the yarn and the roller surface are in uniform contact, avoiding local wear. At the same time, the rotation action can shake off the attached yarn, realize self-cleaning, extend the service life of the equipment and improve the heat conduction stability. The relative position between the heating roller and the shaking roller is adjusted by the lifting drive component to ensure the parallelism of the heating roller. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0019] like Figure 1 This is a schematic diagram of the structure of the present invention. A carbon fiber spreading and warping machine includes a frame 1 and a spreading mechanism 2 arranged on the frame 1. The spreading mechanism 2 includes a mounting base 21, a lifting drive component 22 and a spreading assembly. The output end of the lifting drive component 22 is connected to the mounting base 21. The lifting drive component 22 is used to provide power for the lifting of the spreading assembly. The spreading assembly is arranged on the mounting base 21 and is used to evenly spread multiple bundles of untwisted filament raw materials into sheet yarn.

[0020] like Figure 1 , 2 As shown, the fiber spreading assembly includes a vibrating roller 23, a vibrating drive component 24, a heating roller 25, and a roller drive component 26. The vibrating drive component 24 is fixedly connected to the frame 1, and the output end of the vibrating drive component 24 is drivenly connected to the vibrating roller 23. The vibrating roller 23 is located between the heating rollers 25. The heating roller 25 is rotatably connected to the mounting base 21. The output end of the roller drive component 26 is drivenly connected to the input end of the heating roller 25. The vibrating drive component 24 includes a vibrating motor and a vibrating swing arm. The output end of the vibrating motor is drivenly connected to the input end of the vibrating swing arm, and the output end of the vibrating swing arm is drivenly connected to the vibrating roller 23. The roller drive component 26 includes several sprockets, a chain, and a roller motor. The roller motor is fixedly connected to the frame 1. The sprockets are arranged on the roller body 251 of the roller motor or the heating roller 25. The chain passes around all the sprockets. The vibrating roller 23 and the heating roller 25 work together to disperse vibration and combine with hot pressing to flatten the fibers, thereby improving the uniformity of fiber spreading.

[0021] like Figure 1 , 2 As shown, the heating roller 25 includes a hollow roller body 251 and a heating tube 252. The heating tube 252 is located inside the roller body 251. The heating tube 252 is fixedly connected to the mounting base 21. The roller body 251 and the mounting base 21 are rotatably connected. The heating tube 252 is fixedly installed inside the roller body. The rotation of the roller body 251 makes the heat evenly distributed and avoids yarn accumulation.

[0022] The lifting drive component 22 is a lifting platform, which has a scale.

[0023] By driving the heating roller 25 to rotate actively, the yarn is made to contact the roller surface evenly, avoiding local wear. At the same time, the rotation action can shake off the attached yarn, achieving self-cleaning, extending the equipment life and improving the heat conduction stability. The relative position between the heating roller 25 and the shaking roller 23 is adjusted by the lifting drive component 22 to ensure the parallelism of the heating roller. The operator can quickly adjust the wrap angle height according to the scale to ensure the parallelism of the two rollers, simplifying the adjustment process and improving the uniformity of fiber spreading.

[0024] like Figure 1 As shown, the warping machine also includes a cleaning mechanism 4, which is located below the fiber spreading mechanism 2. The cleaning mechanism 4 is used to collect the carbon fiber fuzz, waste filaments and other impurities and debris that fall from the fiber spreading mechanism 2.

[0025] The cleaning mechanism 4 includes a conveyor belt 41 and a waste trough 42. The conveyor belt 41 is fixedly connected to the frame 1, and the waste trough 42 is fixedly connected to the frame 1. The waste trough 42 is connected to the output end of the conveyor belt 41. The conveyor belt and waste trough 42 are added below the fiber spreading mechanism to automatically collect and transport the shed fuzz and waste yarn, reduce the frequency of downtime for cleaning, maintain a clean production environment, and improve the continuous operation capability of the equipment.

[0026] Work process:

[0027] Fiber spreading stage: Multiple bundles of untwisted filament raw materials are initially dispersed by high-frequency vibration of the vibrating roller 23, and then enter between a pair of heating rollers 25 driven by roller drive component 26; the heating rollers 25 rotate actively through chain drive, and the heating tubes 252 inside the rollers provide a stable heat source. Under the action of rotation, extrusion and heating, the bundled filaments are spread into uniform sheet yarns; the lifting drive component 22 adjusts the height of the mounting base 21 according to the scale markings to precisely control the wrap angle of the heating rollers.

[0028] Waste cleaning stage: During the fiber spreading process, the lint and waste yarn that fall off fall to the conveyor belt 41. The conveyor belt starts at regular intervals to transport the waste to the waste trough 42 for centralized processing, realizing automated cleaning.
