Description

Technical Field

[0001] This utility model belongs to the technical field of prepreg yarn spreading mechanism, specifically a prepreg yarn spreading mechanism with a guide and leak-proof structure. Background Technology

[0002] The prepreg spreading mechanism is a core equipment component in the production of composite prepregs. It is mainly used for fiber dispersion treatment in the production process of fiber-reinforced prepregs. Its core function is to spread and flatten the tightly aggregated fiber bundles through mechanical or physical methods to form a uniformly distributed fiber thin layer, providing an ideal fiber arrangement for subsequent resin impregnation.

[0003] When using existing prepreg spreading mechanisms, the surface of the spreading rollers is relatively smooth, which can cause the fibers to shift or become scattered on both sides during the spreading process. This can easily lead to fiber knots, requiring a long time to process the knots afterward, making the prepreg spreading mechanism inconvenient to use. Summary of the Invention

[0004] The purpose of this invention is to provide a prepreg yarn spreading mechanism with a guiding and leak-proof structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a prepreg yarn spreading mechanism with a guiding and leak-proof structure, comprising a machine body and spreading rollers, wherein the machine body is provided with uniformly distributed spreading rollers, and the surface of the spreading rollers is provided with symmetrically distributed guiding and leak-proof mechanisms, wherein the guiding and leak-proof mechanisms include a fixing frame disposed on the surface of the spreading rollers, one end of the fixing frame is provided with a fixing ring, and one side of the fixing frame is provided with a rotating wheel.

[0006] Preferably, one side of the rotating wheel is provided with a threaded rod extending into the interior of the fixed frame, and the surface of the threaded rod is provided with gears.

[0007] Preferably, one end of the gear is meshed with a gear ring, and one end of the gear ring is provided with a T-shaped rod extending into the interior of the fixed frame. A first spring is welded between the T-shaped rod and the fixed frame.

[0008] Preferably, the threaded rod surface is provided with a displacement block, one end of the displacement block is provided with a connecting rod extending to the outside of the fixed frame, and one end of the fixed frame is provided with a movable ring.

[0009] Preferably, anti-knotting mechanisms extending outward are provided on both sides of the interior of the machine body. The anti-knotting mechanism includes fixing blocks symmetrically distributed inside the machine body, and an mounting plate is provided on the side of the machine body near the fixing blocks.

[0010] Preferably, connecting blocks are provided on both sides of the mounting plate, and the two connecting blocks are fitted onto the surface of the fixing block, and a symmetrically distributed mounting frame is provided at one end of the machine body.

[0011] Preferably, a limiting plate is provided inside the mounting frame, and one end of the limiting plate is provided with a pull rod extending to the outside of the mounting frame.

[0012] Preferably, a second spring is welded between the limiting plate and the mounting frame, one end of the limiting plate is provided with a locking rod extending into the interior of the fixing block, and one side of the mounting frame is provided with a limiting rod extending into the interior.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. When using this utility model, first, the fixing frame is placed on the surface of the spreading roller. Then, the T-shaped rod is pulled to separate the toothed ring from the gear. Then, the rotating wheel is rotated to move the movable ring. When the movable ring moves, it can clamp the spreading roller, so that the fixing frame can be fixed on the surface of the spreading roller, thereby guiding the fiber and preventing the fiber from leaking out when it is on the surface of the spreading roller. At the same time, it can assist in clamping the spreading roller, thereby improving the guiding and leak-proof effect of this utility model when spreading the fiber.

[0015] 2. This utility model involves pulling the limiting rod to release its obstruction of the pull rod, allowing the pull rod to slide within the mounting frame. Pulling the pull rod then moves the locking rod, and the limiting rod is inserted into another hole to restrict the limiting plate. At this point, the second spring is compressed. Next, the connecting block on the mounting plate passes through the fixing block to below the locking rod. The limiting rod is then removed, and the second spring's elasticity resets the limiting plate, allowing the locking rod to pass above the connecting block and be embedded in the fixing block for locking. This allows the mounting plate to be quickly installed on both sides of the machine body, preventing fibers from clumping together during yarn spreading and thus improving the limiting effect.

[0022] 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.

[0023] Please see Figures 1-3 It can be seen that this utility model provides a technical solution:

[0024] exist Figure 1 In the middle: The machine body 1 is provided with evenly distributed yarn spreading rollers 2. The surface of the yarn spreading rollers 2 is provided with symmetrically distributed guide and anti-leakage mechanisms 3. The guide and anti-leakage mechanism 3 includes a fixing frame 301 provided on the surface of the yarn spreading rollers 2. One end of the fixing frame 301 is provided with a fixing ring 302, and one side of the fixing frame 301 is provided with a rotating wheel 303.

[0025] The machine body 1 is equipped with a yarn spreading roller 2. The fibers are placed on the surface of the yarn spreading roller 2 and spread out. Then, the fixing frame 301 is fitted onto the surface of the yarn spreading roller 2, and the rotating wheel 303 is rotated to fix the fixing frame 301.

[0026] exist Figure 3 In the middle: A threaded rod 304 extending into the fixed frame 301 is provided on one side of the rotating wheel 303, and a gear 305 is provided on the surface of the threaded rod 304.

[0027] Rotating the rotating wheel 303 causes the rotating wheel 303 to drive the gear 305 on its surface to rotate.

[0028] exist Figure 3 In the middle: one end of the gear 305 is meshed with a gear ring 306, and one end of the gear ring 306 is provided with a T-shaped rod 307 extending into the interior of the fixed frame 301. A first spring 308 is welded between the T-shaped rod 307 and the fixed frame 301.

[0029] The gear 305 is engaged by the gear ring 306, which restricts the gear 305. The T-shaped rod 307 connected to one end of the gear ring 306 forms an elastic structure with the fixed frame 301, which can pull the gear ring 306 and the T-shaped rod 307 as a whole, so that the gear ring 306 is disengaged from the gear 305.

[0030] exist Figure 3 In the middle: a displacement block 309 is provided on the surface of the threaded rod 304, and a connecting rod 310 extending to the outside of the fixed frame 301 is provided at one end of the displacement block 309, and a movable ring 311 is provided at one end of the fixed frame 301.

[0031] Rotating the rotating wheel 303 causes the threaded rod 304 to rotate, which in turn moves the displacement block 309 connected to the surface thread. At the same time, the displacement block 309 moves the connecting rod 310 and the movable ring 311.

[0032] See Figures 1-3 It can be seen that, firstly, the fixing frame 301 is fitted onto the surface of the yarn spreading roller 2, so that the fixing ring 302 contacts the yarn spreading roller 2. Then, the T-shaped rod 307 is pulled, so that the T-shaped rod 307 compresses the first spring 308 when it moves. When the T-shaped rod 307 moves, it drives the gear ring 306 to move, so that the gear ring 306 separates from the gear 305. Then, the rotating wheel 303 is rotated, so that the rotating wheel 303 drives the threaded rod 304 to rotate, thereby driving the displacement block 309 to move. At the same time, the displacement block 309 moves. 09 When moving, it drives the connecting rod 310 to move, which in turn drives the movable ring 311 to move. When moving, the movable ring 311 can clamp the spreading roller 2, so that the fixed frame 301 is fixed on the surface of the spreading roller 2, thereby guiding the fiber. When the fiber is on the surface of the spreading roller 2, the fixed frame 301 can prevent the fiber from detaching from the spreading roller 2 and causing the fiber to leak out. At the same time, it can also assist in clamping the spreading roller 2, thereby improving the guiding and leak-proof effect of the present invention when spreading the fiber.

[0033] Specifically: Since the surface of the yarn spreading roller 2 is relatively smooth, a rubber pad can be provided on the inner side of the guide leak prevention mechanism 3, i.e. the contact surface with the yarn spreading roller 2, or a textured surface can be provided on the inner side of the guide leak prevention mechanism 3 to prevent relative rotation or sliding between the yarn spreading roller 2 and the guide leak prevention mechanism 3.

[0034] exist Figure 4 In the middle: both sides inside the body 1 are provided with anti-knotting mechanisms 4 extending to the outside. The anti-knotting mechanism 4 includes fixing blocks 401 symmetrically distributed inside the body 1. An installation plate 402 is provided on the side of the body 1 near the fixing blocks 401.

[0035] Mounting plates 402 are provided on both sides inside the body 1, and the mounting plates 402 guide the fibers.

[0036] exist Figure 4 In the middle: both sides of the mounting plate 402 are provided with connecting blocks 403, and both connecting blocks 403 are fitted onto the surface of the fixing block 401. One end of the body 1 is provided with symmetrically distributed mounting frames 404.

[0037] By fitting the connecting blocks 403 on both sides of the mounting plate 402 onto the surface of the fixing block 401, the mounting plate 402 can be limited, and a mounting frame 404 is provided at one end of the body 1.

[0038] exist Figure 4 In the middle: a limiting plate 405 is provided inside the mounting frame 404, and a pull rod 406 extending to the outside of the mounting frame 404 is provided at one end of the limiting plate 405.

[0039] Pulling the lever 406 moves the limiting plate 405 inside the mounting frame 404.

[0040] exist Figure 4 In the middle: a second spring 407 is welded between the limiting plate 405 and the mounting frame 404. One end of the limiting plate 405 is provided with a locking rod 408 extending into the fixed block 401, and one side of the mounting frame 404 is provided with a limiting rod 409 extending into the interior.

[0041] The limiting plate 405 can compress the second spring 407, and the limiting plate 405 drives the locking rod 408 to move, so that the locking rod 408 restricts the connecting block 403. At the same time, the limiting rod 409 on one side of the mounting frame 404 restricts the limiting plate 405.

[0042] See Figure 1 , Figure 2 and Figure 4It is known that the limiting rod 409 penetrates the mounting frame 404. The mounting frame 404 has two limiting holes (front and back). First, pulling the limiting rod 409 releases its obstruction of the pull rod 406, allowing the pull rod 406 to slide within the mounting frame 404. Then, pulling the pull rod 406 causes it to move the limiting plate 405. During this movement, the limiting plate 405 compresses the second spring 407 and also moves the locking rod 408. Finally, the limiting rod 409 is inserted into the other hole, thus limiting the locking plate... 405 is used for restriction. At this time, the second spring 407 is in a compressed state. Then, the connecting block 403 on the mounting plate 402 passes through the fixing block 401 to the bottom of the locking rod 408. Then, the limiting rod 409 is removed. The elastic force of the second spring 407 causes the limiting plate 405 to reset, so that the locking rod 408 passes through the top of the connecting block 403 and is then embedded into the fixing block 401 for locking. This allows the mounting plate 402 to be quickly installed on both sides of the machine body 1, preventing the fibers from coming into contact with each other and clumping during the yarn spreading process, thereby improving the limiting effect.

[0043] In summary, the fixing frame 301 is first fitted onto the surface of the spreading roller 2, so that the fixing ring 302 contacts the spreading roller 2. Then, the T-shaped rod 307 is pulled to compress the first spring 308. When the T-shaped rod 307 moves, it causes the toothed ring 306 to separate from the gear 305. Then, the rotating wheel 303 is rotated, causing the threaded rod 304 to rotate, which in turn causes the displacement block 309 and the connecting rod 310 to move. When the connecting rod 310 moves, it causes the movable ring 311 to clamp the spreading roller 2, thereby fixing the fixing frame 301 to the surface of the spreading roller 2, thus guiding the fiber and preventing the fiber from leaking out when it is on the surface of the spreading roller 2. At the same time, it can provide auxiliary clamping for the spreading roller 2, thereby improving the guiding and leak-proof effect of the present invention when spreading the fiber. The contents not described in detail in this description are the prior art known to those skilled in the art.

[0044] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
