DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0020] The implementation of the present utility model will be described in detail below in conjunction with specific embodiments.
[0021] According to Figures 1-4 As shown, a small and portable thermoplastic slitting device includes a base 1;
[0022] At the center and in front of the left side of the top of the base 1, fixed seats 2 are fixedly connected. Between the centers of the opposite sides of the two fixed seats 2, a traction roller 3 is rotatably connected. On the left side of the center of the top of the base 1, a slitting assembly 4 is arranged. In front of the right side of the top of the base 1, a baffle 6 is fixedly connected. Above the inside of the baffle 6, a measuring assembly 7 is arranged. At the rear of the right side of the top of the base 1, a limiting assembly 5 is arranged; during operation, the prepreg or film with a thickness of 6.35 mm or 12.7 mm is placed near the baffle 6, and is limited by the limiting assembly 5, and then is cut by the slitting assembly 4. Also, the width of the prepreg can be adjusted by the limiting assembly 5 to adjust the size of the material before slitting. Finally, the prepreg is slit into a size of 2 mm. When the slitting assembly 4 is slitting, the rotation of the traction roller 3 also plays a fixing role, and the two cooperate with each other. At the same time, the measuring assembly 7 inside the baffle 6 can measure the distance between the baffle 6 and the limiting assembly 5. Therefore, the present utility model can slit the prepreg into a width of 2 mm, and the size conforms to the rotor edge-filling process. At the same time, the device is small and easy to carry, the width is adjustable, and the operation is simple, so the efficiency can be improved during the production process, and manual cutting can be replaced, thus making the device highly practical.
[0023] The slitting assembly 4 includes two support plates 403 fixedly connected to the left side of the center of the top of the base 1. Between the two support plates 403, a rotating rod 402 is rotatably connected. The rear end of the rotating rod 402 penetrates through the rear surface of the rear support plate 403. In front of the outer surface of the rotating rod 402, a cutter 404 is fixedly connected. At the rear of the left side of the center of the top of the base 1, a motor 401 is fixedly installed, and the output end of the motor 401 is fixedly connected to the rear end of the rotating rod 402; during operation, the motor 401 is connected to an external power supply to make the motor 401 work. After the motor 401 works, it drives the rotating rod 402 supported by the two support plates 403 to rotate. Then, after the rotating rod 402 rotates, it drives the cutter 404 to rotate. The rotation speed of the cutter 404 is faster than the advancing speed of the material, and the prepreg is frictionally cut off.
[0024] The cutter 404 corresponds to the traction roller 3; when working, the cutter 404 is convenient for cutting the prepreg.
[0025] The limit assembly 5 includes a limiter 501 arranged at the rear right side of the top of the base 1, and the limiter 501 has upper and lower penetrating adjustment slots 503 on both the left and right sides. A threaded rod 502 is fixedly connected to the top of the base 1 corresponding to the adjustment slot 503, and the top end of the threaded rod 502 penetrates the adjustment slot 503, and a rotating nut 504 is threadedly connected above the outer surface of the threaded rod 502; when working, the prepreg located between the retaining edge 6 and the limiter 501 is limited by the rotating nut 504 and the limiter 501 in a clamped state with the base 1, and the rotating nut 504 is rotated to separate it from the contact with the limiter 501, and then the position of the limiter 501 can be adjusted by the movement of the threaded rod 502 and the adjustment slot 503, so that the distance between the limiter 501 and the retaining edge 6 can be adjusted, and the width of the prepreg can be adjusted.
[0026] The bottom of the rotating nut 504 fits with the top of the stopper 501; during operation, the rotating nut 504 can be rotated to separate the rotating nut 504 from the stopper 501, and the adjustment of the stopper 501 is facilitated.
[0027] The measuring assembly 7 includes a storage slot 701 provided above the rear surface of the retaining edge 6, a slot 704 is provided on the right side of the lower surface of the storage slot 701, a rod 705 is rotatably connected to the slot 704 via a bearing, the outer surface of the rod 705 is located inside the storage slot 701 and is fixedly connected to a swivel 703, the outer surface of the swivel 703 is fixedly connected to a measuring ruler 702, and the measuring ruler 702 is located inside the storage slot 701; when working, the measuring ruler 702 is rotated so that the measuring ruler 702 is rotated out of the storage slot 701 through the rotation of the swivel 703 for use, and the swivel 703 is rotated under the limit of the rotation connection between the rod 705 and the slot 704, and then the measuring ruler 702 can be used after being rotated out to measure the distance between the retaining edge 6 and the stopper 501.
[0028] On the upper surface of the right side inside the storage groove 701, an inner groove 707 is provided. A pressing rod 706 is slidably connected inside the inner groove 707, and the bottom end of the pressing rod 706 is in contact with the top of the rotating ring 703. A spring 708 is fixedly connected between the top end of the pressing rod 706 and the upper surface inside the inner groove 707. During operation, when the spring 708 is in a compressed state, it has a rebounding force to drive the pressing rod 706 to exert a certain extrusion on the top of the rotating ring 703. Therefore, when the rotating ring 703 and the measuring scale 702 are stored inside the storage groove 701, they are relatively stable and not easily rotated out of the storage groove 701 when being collided. At the same time, the pressing rod 706 is in contact with the rotating ring 703 and does not affect manual rotation for use.
