The distance between the outermost protrusion and the inner surface of the female mold is the same as the distance between each other.

The existing wiring device assembles the wires back and forth through a wiring head, and the outermost protrusions are repeatedly entangled during the wiring process of the glass fiber.

[0012] More preferably, the extension portion is lower than the main body, and the recess is formed by the upper surface of the extension portion being recessed downward.

[0013] Preferably, the wire cutting mechanism is liftably provided on the frame, and the wire cutting mechanism is aligned with the first left clamping assembly along the second direction.

[0014] A production device for producing fiberglass reinforced plastic gratings, comprising the aforementioned wire laying device for producing fiberglass reinforced plastic gratings, the production device for producing fiberglass reinforced plastic gratings further comprising a mold disposed on the frame, the mold and a plurality of sets of the first clamping mechanisms being arranged at intervals along the second direction, and the movable seat being movable along the second direction to above the mold;

[0015] The mold includes a work table provided on the frame, a baffle provided circumferentially on the upper surface of the work table, a plurality of core groups arranged in the baffle in a sequentially spaced manner along the second direction, a lifting mechanism provided on the frame and located below the work table in a liftable manner, and a through hole provided on the work table for the lifting mechanism to pass through.

[0016] The core mold group includes a plurality of core molds arranged on the work table in sequence and spaced apart along the first direction, and the core molds and the through holes are staggered on the work table; the core mold includes a lower connecting section connected to the work table and an upper connecting section connected above the lower connecting section, and the lower connecting section and the upper connecting section are respectively gradually converged inward in an upward direction, and the inward convergence angle of the lower connecting section is smaller than the inward convergence angle of the upper connecting section, and the interval between adjacent upper connecting sections gradually decreases from top to bottom, and the interval between adjacent lower connecting sections gradually decreases from top to bottom.

[0021] Cutting the glass fibers to equal lengths in advance and feeding the cut glass fibers directly into the mold can avoid the uneven edges of the fiberglass grating produced by winding the fibers directly through the male mold assembly, thereby ensuring the overall quality of the fiberglass grating.

[0022] Since the free ends of the glass fibers are poorly uniform, the first right clamping assembly integrally clamps the free ends of the glass fibers to prevent them from being excessively dispersed, so that the second right clamping assembly can effectively clamp the free ends of the glass fibers simply by descending linearly, thereby improving the clamping efficiency.

[0023] By setting the specific shape of the mold core, it can guide the glass fibers that fall after being cut, so that the glass fibers can stably fall into the horizontal or vertical intervals between the mold cores, thereby producing an overall uniform and relatively high-quality fiberglass grating;

[0024] By setting the retraction angles of the lower connecting section and the upper connecting section to be different, the upper connecting section with a larger opening angle between the two sections plays a guiding role for the glass fibers, so that the glass fibers can fall to the specified position through the upper connecting section; the lower connecting section with a smaller opening angle between the two sections plays a guiding role for the glass fibers while also playing a limiting role for the glass fibers, so that the falling glass fibers can be stably confined between the lower connecting sections; the lower connecting section can also play a positive role in demolding after the glass fiber grating is press-formed, making demolding of the glass fiber grating easier.

[0043] The disclosure below provides many different embodiments or examples for implementing different structures of the embodiments of the present invention. In order to simplify the disclosure of the embodiments of the present invention, the components and configurations of specific examples are described below. Of course, these are merely examples and are not intended to limit the embodiments of the present invention. In addition, the embodiments of the present invention may repeat reference numerals and / or reference letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or configurations discussed.

[0044] See also Figure 1-3 As shown, this embodiment provides a wire laying device for preparing glass fiber reinforced plastic grating, comprising a frame 1, a plurality of groups of wires arranged along a first direction (ie Figure 1 The first clamping mechanism 2 is arranged on the frame 1 in sequence (in the direction of the arrow in the figure), and the first clamping mechanism 2 includes a first left clamping component 21 and a first right clamping component 22 arranged at intervals along the second direction, wherein the second direction is perpendicular to the first direction, and both are parallel to the horizontal plane.

[0045] The above-mentioned wire laying device also includes a wire cutting mechanism 3 arranged on the outside of the first left clamping component 21, a movable seat 4 that can be raised and lowered above the first clamping mechanism 2, and multiple groups of second clamping mechanisms 5 arranged on the movable seat 4 in sequence along the first direction. The second clamping mechanism 5 includes a second left clamping component 51 and a second right clamping component 52 arranged at intervals along the second direction. The second clamping mechanisms 5 are arranged one by one above the first clamping mechanism 2.

[0046] During wiring, a wiring head (not shown) places the free end of the glass fiber 7 into the first right clamping assembly 22. After being clamped by the first right clamping assembly 22, the wiring head then passes leftward through the first left clamping assembly 21. After being clamped by the first left clamping assembly 21, the wiring head then passes leftward through the cutting mechanism 3. The cutting mechanism 3 cuts the glass fiber 7 on the right side of the wiring head to obtain pre-cut glass fibers 7 of substantially equal length. These glass fibers 7 are arranged in sequence along the first direction. The movable seat 4 descends and, after reaching its position, clamps the glass fibers 7 on the first clamping mechanism 2 through the second clamping mechanism 5. The first clamping mechanism 2 then releases these glass fibers 7, and the movable seat 4 rises and returns to its original position, carrying all the glass fibers 7.

[0047] By cutting the glass fibers 7 to equal lengths in advance and feeding the cut glass fibers 7 directly into the mold 6, it is possible to avoid uneven edges of the fiberglass grating produced by winding the fibers directly through the male mold assembly, thereby ensuring the overall quality of the fiberglass grating.

[0048] There are multiple cutting mechanisms 3, each aligned with a corresponding first left clamping assembly 21 along the second direction. In this embodiment, the cutting mechanisms 3 are arbitrarily mounted on the frame 1. After the first left clamping assembly 21 clamps the glass fiber 7, the wiring head passes leftward over the cutting mechanism 3. The cutting mechanism 3 rises, cuts the glass fiber 7 at the corresponding position, and then descends to reset.

[0049] See also Figure 2 As shown, the second left clamping assembly 51 is located between the wire cutting mechanism 3 and the corresponding first left clamping assembly 21, the first right clamping assembly 22 is used to clamp the free end of the glass fiber 7 as a whole, the first right clamping assembly 22 is provided with a recess 2213, and the second right clamping assembly 52 is provided with a clamping protrusion 521 for fittingly extending into the recess 2213.

[0050] Since the free end of the glass fiber 7 is less uniform, the free end of the glass fiber 7 can be prevented from being excessively dispersed by the first right clamping assembly 22 as a whole, so that the second right clamping assembly 52 can effectively clamp the free end of the glass fiber 7 only by descending linearly, thereby improving the clamping efficiency and thus improving the wire laying efficiency.

[0051] See also Figure 6 As shown, the first left clamping assembly 21 includes a pair of first left clamping parts 211 arranged along the first direction and capable of opening and closing relative to each other, and a plurality of first left protrusions 212 arranged at intervals along the second direction and protruding outwardly on the inner side surfaces of the first left clamping parts 211, that is, a row of first left protrusions 212 are respectively provided on the opposite sides of the two first left clamping parts 211, and the two opposite rows of first left protrusions 212 are staggered in sequence along the second direction. This arrangement can effectively clamp the glass fiber 7.

[0052] See also Figure 3 、 Figure 7 As shown, the first right clamping assembly 22 includes a pair of first right clamping parts 221 arranged along the first direction and capable of opening and closing relative to each other, and a plurality of first right protrusions 222 arranged at intervals along the second direction and protruding outwardly on the inner side surfaces of the first right clamping parts 221, that is, a row of first right protrusions 222 are respectively provided on the opposite sides of the two first right clamping parts 221, and the two opposite rows of first right protrusions 222 are staggered in sequence along the second direction. This arrangement can effectively clamp the glass fiber 7.

[0053] Among them, the first right clamping portion 221 includes a main body 2211 for connecting to the first right convex portion 222, an extension portion 2212 formed by extending the main body 2211 to the right, and the above-mentioned recess 2213 is opened in the extension portion 2212. A pair of extension portions 2212 are used to clamp the glass fiber 7 in cooperation with each other. The glass fiber 7 is exposed in the recess 2213, so that it can be clamped by the clamping protrusion 521 extending into the recess 2213.

[0054] See also Figure 3 As shown, in this embodiment, the top surface of the extension portion 2212 is lower than the top surface of the body 2211 , and the recess 2213 is formed by the upper surface of the extension portion 2212 being recessed downward.

[0055] See also Figure 4-5 As shown, this embodiment provides a production device for producing fiberglass reinforced plastic grating, including the aforementioned wire laying device for producing fiberglass reinforced plastic grating. The production device for producing fiberglass reinforced plastic grating also includes a mold 6 mounted on a frame 1. The mold 6 and multiple sets of first clamping mechanisms 2 are arranged in a spaced relationship along a second direction. The movable seat 4 can move in the second direction to above the mold 6.

[0056] Figure 4 This is the first working state of the production device for preparing fiberglass reinforced plastic gratings, where the movable seat 4 is located directly above the first clamping mechanism 2 and is used to clamp the glass fiber 7; Figure 5 This is the second working state of the production device for preparing fiberglass reinforced plastic grating. The movable seat 4 is located directly above the mold 6 and is used to release the glass fiber 7 after descending to a suitable height, allowing it to fall freely into the mold 6.

[0057] See also Figure 8-10 As shown, the mold 6 includes a worktable 61 mounted on the frame 1, a baffle 62 circumferentially disposed on the upper surface of the worktable 61, multiple rows of core assemblies spaced sequentially along a second direction within the baffle 62, a lifting mechanism 63 movably mounted on the frame 1 and positioned below the worktable 61, and through-holes 611 formed in the worktable 61 for the lifting mechanism 63 to pass through. The worktable 61 and baffle 62 form the female mold, while the multiple rows of core assemblies form the male mold, which cooperate to produce the fiberglass reinforced plastic grating. Through-holes 611 are provided at the intersection of the transverse and longitudinal spacings between the core assemblies 64, allowing the lifting mechanism 63 to eject the finished fiberglass reinforced plastic grating.

[0058] The mold core assembly includes a plurality of mold cores 64 arranged on the worktable 61 in a sequentially spaced arrangement along a first direction. The mold cores 64 and the through-holes 611 are staggered on the worktable 61. The mold core 64 includes a lower connecting section 641 connected to the worktable 61 and an upper connecting section 642 connected above the lower connecting section 641. The lower connecting section 641 and the upper connecting section 642 each gradually converge inward in an upward direction. The inward convergence angle of the lower connecting section 641 is smaller than the inward convergence angle of the upper connecting section 642. The spacing between adjacent upper connecting sections 642 gradually decreases from top to bottom, and the spacing between adjacent lower connecting sections 641 gradually decreases from top to bottom.

[0059] The lower connecting section 641 converges inwardly at an angle α, where 0° < α ≤ 8°. In this embodiment, α is 3°. The upper connecting section 642 converges inwardly at an angle β, where 0° < β < 90°. In this embodiment, β is 40°. The inward convergence angle β of the upper connecting section 642 is much greater than the inward convergence angle α of the lower connecting section 641.

[0060] By setting the retraction angles of the lower connecting section 641 and the upper connecting section 642 to be different, the upper connecting section 642 with a larger opening angle between the two sections plays a guiding role for the glass fiber 7, so that the glass fiber 7 can fall to the specified position through the upper connecting section 642; the lower connecting section 641 with a smaller opening angle between the two sections not only plays a guiding role for the glass fiber 7, but also plays a limiting role for the glass fiber 7, so that the falling glass fiber 7 can be stably confined between the lower connecting sections 641; the lower connecting section 641 can also play a positive role in demolding after the glass fiber grating is press-formed, making demolding of the glass fiber grating easier.

[0061] See also Figure 9-11 As shown, the lower connecting section 641 and the upper connecting section 642 are each polyhedrons. In this embodiment, the lower connecting section 641 and the upper connecting section 642 are each tetrahedrons. The bottom surface of the tetrahedron is parallel to the worktable 61, and the four side surfaces of the tetrahedron are aligned with the other four tetrahedrons on the four sides. The lower connecting section 641 and the upper connecting section 642 are arranged coaxially, and their cross-sectional areas gradually decrease in the upward direction. The top angle of the lower connecting section 641 is smaller than the top angle of the upper connecting section 642. The lower connecting section 641 and the upper connecting section 642 have a smooth transition at the connection to prevent snagging of the fallen glass fiber 7.

[0062] Wherein, A is the height of the formed FRP grating product, B is the shrinkage of the FRP grating product, and H is the total height of the mold core 64. The height H of the lower connecting section 641 is 下 =A+B, the height H of the upper connecting section 642 上 =H-(A+B).

[0063] In another embodiment, the lower connecting section 641 and the upper connecting section 642 are each cone-shaped, with the bottom surfaces of the cones parallel to the worktable 61. The lower connecting section 641 and the upper connecting section 642 each taper upward, with the taper angle of the lower connecting section 641 being smaller than that of the upper connecting section 642. The lower connecting section 641 and the upper connecting section 642 have a smooth transition at the connection to prevent snagging of the fallen glass fiber 7.

[0064] In this embodiment, the direction of the glass fiber 7 is consistent with the direction of the longitudinal spacing in the mold 6. When it is necessary to arrange the glass fiber 7 in the lateral spacing of the mold core 64, it is only necessary to set up another set of wire-laying devices, and accordingly set the first left clamping assembly 21 and the first right clamping assembly 22 to be arranged at intervals along the first direction. In this set of wire-laying devices, the corresponding second left clamping assembly 51 and the second right clamping assembly 52 are also arranged at intervals along the first direction, and the wire-laying heads lay wires along the first direction.

[0065] The working process of this embodiment is described in detail below:

[0066] A wiring head (not shown) places the free end of the glass fiber 7 into the first right clamping assembly 22. After being clamped by the first right clamping assembly 22, the wiring head then passes leftward through the first left clamping assembly 21. After the glass fiber 7 is clamped by the first left clamping assembly 21, the wiring head then passes leftward through the cutting mechanism 3. The cutting mechanism 3 rises and cuts the glass fiber 7 on the right side of the wiring head to obtain pre-cut glass fibers 7 of substantially equal length. These glass fibers 7 are arranged in sequence along the first direction.

[0067] The movable seat 4 descends and, after it has fallen into place, clamps the glass fibers 7 on the first clamping mechanism 2 through the second clamping mechanism 5. The first clamping mechanism 2 releases the glass fibers 7. The movable seat 4 ascends and returns to its original position with all the glass fibers 7 and moves horizontally to the right to be directly above the mold 6. The glass fibers 7 are aligned with the longitudinal spacing between the mold cores 64 in the vertical direction, and their two ends are located on the inner sides of the baffle 62.

[0068] Loosen the glass fiber 7 and allow it to fall downward into the longitudinal interval of the mold core 64. During the falling process of the glass fiber 7, the upper connecting section 642 and the lower connecting section 641 are used to guide the glass fiber 7 so that the glass fiber 7 can fall stably between the lower connecting section 641. Before or after, resin is injected into the mold 6 and then compacted by the pressing plate.

[0069] When it is necessary to lay wires in the lateral spaces between the mold cores 64, another set of wire laying devices is started.

[0070] The above embodiments are only for illustrating the technical concept and features of the present invention. Their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of protection of the present invention.
