[0009] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0010] Please see Figure 1 A prepreg yarn shaking device with adjustable shaking roller includes a main body 102, on which a processing path for carbon fiber 1 is provided, and an outer frame 101 is fixedly installed at both ends of the main body 102. A longitudinal shaking mechanism 2 and a transverse shaking mechanism 3 for shaking the carbon fiber 1 are fixedly installed in the middle between the outer frame 101 and the main body 102. Specifically, when the carbon fiber 1 enters the predetermined entry line of the device, the longitudinal shaking mechanism 2 and the transverse shaking mechanism 3 shake the carbon fiber 1 longitudinally and laterally, respectively. The longitudinal shaking of the longitudinal shaking mechanism 2 and the transverse shaking of the transverse shaking mechanism 3 enable the carbon fiber 1 to be better compounded with the resin.

[0011] Please see Figure 2 and Figure 3 The protruding part of the main body 102 has two pairs of opposite holes. A protective sleeve 307 is fixedly installed in the holes of the protruding part of the main body 102. A transverse roller 306 is fixedly installed in the center of the protective sleeve 307. The holes of the protruding part of the main body 102 are used to install the protective sleeve 307, while the protective sleeves 307 on both sides are used to protect the transverse roller 306 fixed in the center. The transverse roller 306 is used to transversely shake the passing carbon fiber 1.

[0012] Please see Figure 2 and Figure 3 The main body 102 has a pair of opposing grooves on its protruding part. A guide sleeve 204 is slidably installed in the groove of the protruding part of the main body 102. A longitudinal roller 205 is fixedly installed in the center of the guide sleeve 204. The groove of the protruding part of the main body 102 is used to install the guide sleeve 204, while the guide sleeves 204 on both sides are used to protect the longitudinal roller 205 fixed in the center. The longitudinal roller 205 is used to longitudinally shake the passing carbon fiber 1, while the groove of the main body 102 is used to limit the shaking range of the longitudinal roller 205.

[0013] Please see Figure 3 The longitudinal shaking mechanism 2 includes a longitudinal motor 201, which is fixedly installed at one end of the outer frame 101 facing the main body 102. A cam 202 is rotatably installed at the output end of the longitudinal motor 201. When in use, the longitudinal motor 201 rotates, and the output end of the longitudinal motor 201 drives the cam 202 to rotate, providing a shaking force for the longitudinal shaking mechanism 2.

[0014] Please see Figure 4 A ball bearing 203 is slidably mounted on the upper end of the cam 202. The ball bearing 203 is slidably mounted in the guide sleeve 204. When the cam 202 rotates, it will push up the ball bearing 203, which will push up the guide sleeve 204. The ball bearing 203 reduces the wear of the cam 202 when it rotates and extends the service life of the cam 202. When it is necessary to adjust the vibration amplitude, simply move the cam 202.

[0015] Please see Figure 5 The horizontal shaking mechanism 3 includes a rotary motor 301, which is fixedly installed on the other end of the outer frame 101 facing the main body 102. A shaft cover 305 is fixedly installed on the output end of the rotary motor 301 near the main body 102. A rotating disk 302 is rotatably installed on the output end of the rotary motor 301 near the outer frame 101. A pneumatic telescopic cylinder 303 is fixedly installed on the protruding part of the rotating disk 302. A fixed disk 304 is fixedly installed on the end of the pneumatic telescopic cylinder 303 away from the outer frame 101. The output end of the guide sleeve 204 is fixedly installed on the end of the protective sleeve 307 near the outer frame 101. In use, the pneumatic telescopic bars on both sides extend and retract in coordination, so that the protective sleeve 307 can drive the horizontal roller 306 to perform horizontal reciprocating motion. When it is necessary to change the amplitude, the output end of the rotary motor 301 drives the rotating disk 302, the pneumatic telescopic cylinder 303 and the fixed disk 304 to rotate, rotating to the rotating disk 302 that matches the amplitude.

[0016] Working principle: During use, carbon fiber 1 travels along a preset processing route. As carbon fiber 1 travels, the pneumatic telescopic cylinders 303 on both sides of the transverse roller 306 operate. When one cylinder extends, the other retracts, allowing the transverse roller 306 to perform transverse reciprocating motion, thus fully vibrating the carbon fiber 1 on the transverse roller 306. Simultaneously, the output of the longitudinal motor 201 drives the cam 202 to rotate. When the cam 202 rotates to the point where the smaller diameter end faces upwards, it pushes up the guide sleeve 204. When 204 is lifted, the guide sleeve 204 is also lifted. When the guide sleeve 204 is lifted, it will drive the longitudinal roller 205 upward. When the cam 202 rotates to the end with the larger diameter facing upward, the guide sleeve 204 will fall. When the guide sleeve 204 falls, it will also fall due to inertia. When the guide sleeve 204 falls, it will drive the longitudinal roller 205 to fall, so that the longitudinal roller 205 can perform longitudinal reciprocating motion. Through the movement of the transverse roller 306 and the longitudinal roller 205, the carbon fiber 1 and the resin can be fully compounded.

[0017] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
