[0019] The technical solution of this utility model will be clearly and completely described below through specific embodiments. Example 1

[0020] refer to Figure 1 and Figure 2 This utility model discloses a yarn guiding device for a winding system in grid production, comprising a yarn guiding plate 1, a yarn guiding wheel 2, a yarn guiding needle 3, an angle adjusting mechanism 4, and a rotating bracket 5; the yarn guiding plate 1 is provided with a yarn guiding hole; the yarn guiding plate 1 is mounted on the rotating bracket 5; the angle adjusting mechanism 4 drives the rotating bracket 5 to rotate; a yarn guiding needle frame 6 is provided below the yarn guiding plate 1; the yarn guiding wheel 2 is provided between the yarn guiding plate 1 and the yarn guiding needle frame 6; the yarn guiding needle 3 is mounted on the yarn guiding needle frame 6; and the yarn guiding needle frame 6 is provided with a yarn guiding hole at the corresponding position of the yarn guiding needle 3.

[0021] The yarn guiding device in this embodiment is provided with three yarn guiding needles 3, which are arranged in a straight line.

[0022] The rotating bracket 5 in this embodiment includes two L-shaped side plates and a rear baffle; the two sides of the rear baffle are fixedly connected to the L-shaped side plates; the L-shaped side plates are fixed to the surface of the yarn guide plate 1.

[0023] The rotating bracket 5 in this embodiment facilitates changing the direction of the yarn guiding device, making it convenient for both horizontal and vertical yarn distribution.

[0024] In this embodiment, the angle adjustment mechanism 4 is a rotary cylinder; the rear baffle of the rotary bracket 5 is fixedly installed on the rotary cylinder.

[0025] When the reinforcing yarn traction device of this embodiment is working, the reinforcing yarn is unwound from the yarn frame and pulled by the traction device to be laid in the grid plate.

[0026] After the three sets of reinforcing yarns are unwound from the yarn frame, they pass through the three yarn guide holes on the yarn guide plate, and after passing through the corresponding yarn guide rollers 2, they pass through the corresponding yarn guide needles 3. The reinforcing yarns then exit through the yarn guide holes of the yarn guide needles 3. Then, the driving assembly drives the reinforcing yarn traction device to move longitudinally or laterally, so that the reinforcing yarn is laid inside the grid plate.

[0027] The angle adjustment mechanism set in this embodiment controls the angle of the yarn guide needle 3, which on the one hand reduces the friction between the yarn and the yarn guide needle 3, and on the other hand makes it easier for the yarn to adhere to the resin surface.

[0028] The yarn guide needle 3 of this embodiment includes a hollow yarn guide tube 31 and a spring tube 32; a connecting tube 33 is provided between the spring tube 32 and the yarn guide tube 31; a yarn threading hole is provided inside the connecting tube 33; the yarn guide tube 31 and the spring tube 32 are respectively welded to the upper and lower end faces of the connecting tube 33.

[0029] This embodiment improves the service life of the yarn guide needle by setting the yarn guide needle structure. With the setting of the spring tube, the yarn guide needle itself has a micro-adjustment function, and the spring tube is used to make micro-adjustments in the horizontal and vertical directions.

[0030] In this embodiment, the guide roller 2 includes a roller frame 21, a first guide roller 22, and a second guide roller 23. The top of the roller frame 21 is mounted on the yarn guide plate 1, and the bottom is mounted on the guide needle frame 6. The first guide roller 22 and the second guide roller 23 are arranged sequentially from top to bottom on the roller frame 21. The arrangement of the guide roller 2 in this embodiment allows the reinforcing yarn to unwind smoothly and avoid tangling, and also ensures that the reinforcing yarn has a certain tension during the yarn laying process. Example 2

[0031] This embodiment also includes a spacing adjustment mechanism; the spacing of the yarn guide needle 3 is controlled by the spacing adjustment mechanism; the spacing adjustment mechanism includes an adjustment cylinder 71; the yarn guide needle frame 6 includes a fixed frame and two movable frames slidably connected to the fixed frame on both sides: a yarn guide needle 3 is respectively arranged on the fixed frame and the two movable frames, and the adjustment cylinder 71 drives the movable frames to move and adjust the spacing of the yarn guide needle 3.

[0032] This embodiment, through the setting of the adjustment mechanism, can quickly and conveniently adjust the needle pitch of the yarn guide needle, thereby increasing the spacing between yarns. At the same time, when the yarn guide device turns, by adjusting the spacing, collisions between the yarn guide needle and the grid plate forming bracket are avoided.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Those skilled in the art can make various modifications or equivalent substitutions to the present utility model within its substance and protection scope, and such modifications or equivalent substitutions should also be considered to fall within the protection scope of the present utility model's technical solution.
