[0002] The raw material of the mesh tire production line is chopped strands. Chopped strands are cut into fixed lengths from rolled carbon fiber strands, and then used as the raw material for the next mesh tire production process.

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

[0029] like Figures 1 to 6 As shown, the carbon fiber chopped strands uniform distribution device of this embodiment includes: a base assembly 10, a feed assembly 20, a cloth assembly 30 and a uniform distribution assembly 40. The feed assembly 20 is arranged on the base assembly 10. The cloth assembly 30 includes a weighing structure 31 and a leakage structure 32, the weighing structure 31 is arranged on the base assembly 10, the leakage structure 32 is arranged on the weighing structure 31, and the leakage structure 32 cooperates with the feed assembly 20. The uniform distribution assembly 40 includes a pouring structure 41 and a vibrating screen structure 42, the pouring structure 41 is located at the lower side of the outlet of the leakage structure 32, and the vibrating screen structure 42 is located at the lower side of the pouring structure 41.

[0030] By applying the technical solution of this embodiment, the carbon fiber chopped strands are fed to the distribution component 30 through the feeding component, so that the carbon fiber chopped strands can be initially distributed in preparation for subsequent uniform distribution. The distribution component 30 transfers the carbon fiber chopped strands to the uniform distribution component 40, and the uniform distribution component 40 evenly distributes the carbon fiber chopped strands. The technical solution of this embodiment effectively solves the problem of uneven distribution of carbon fiber chopped strands in the prior art.

[0031] It should be noted that the base assembly 10 can be an integrated structure or a split structure.

[0032] like Figure 1As shown, in the technical solution of this embodiment, the feeding assembly 20 includes a discharge table 21 and a vibration drive unit, the material leakage structure 32 includes a material chute 321 and a funnel 322, the vibration drive unit is arranged on the base assembly 10, the discharge table 21 is tilted on the vibration drive unit, the discharge table 21 is gradually tilted from high to low along the side away from the material chute 321 to the side close to the material chute 321, and the material chute 321 is matched with the feed port of the funnel 322. The vibration of the vibration unit makes the carbon fiber chopped strands on the discharge table 21 gradually fall into the material chute 321, and the material in the material chute 321 enters the funnel 322 under the action of gravity, and the weighing structure 31 weighs the material. When the weight meets the requirements, the material is transferred to the material pouring structure 41. The above structure has a good degree of automation, saves time and labor, and the material is more accurate. It should be noted that the discharge platform 21 is higher than the first end of the material chute 321, and the height of the material chute 321 gradually decreases from the discharge platform 21 to the funnel 322. The material discharge structure 32 also includes a material guide slide, and the two sides of the material guide slide have guard plates, so that the material can enter the material discharge structure 41 according to a predetermined trajectory.

[0033] like Figures 1 to 3 As shown, in the technical solution of this embodiment, the material chute 321 has an arc segment, and the arc segment cooperates with the discharge platform 21. In this way, the matching length of the material chute 321 and the discharge platform 21 is longer, which improves the efficiency of the material from the discharge platform 21 entering the material chute 321, and when the material enters the material chute 321 from the discharge platform 21, the material is not easy to slide out of the material chute 321. It should be noted that the discharge platform 21 is circular, so the matching length of the discharge platform 21 and the material chute 321 is longer, which improves the efficiency of the material from the discharge platform 21 to the material chute 321.

[0034] like Figure 4 As shown, in the technical solution of this embodiment, the material leakage structure 32 also includes a gate drive unit 323 and a gate plate 324.

The above structure is compact, and the material is transferred by gravity, which saves energy. It should be noted that the drive unit is a cylinder, and the funnel 322 also includes two guide rods 325, which are respectively located on both sides of the two side plates, the lower ends of the guide rods 325 are connected to the outward convex plates of the side plates, and the upper ends of the guide rods 325 are connected to the support plate. There are guide blocks on both sides of the gate plate 324, each guide block has a light hole, and the guide rods 325 are inserted into the light hole. The discharge port is formed on the side of the funnel 322 opposite to the inclined plate.

[0036] like Figures 1 to 5 As shown, in the technical solution of this embodiment, the material reversing structure 41 includes a material reversing belt, a rack, a flip gear and a flip motor, the rack is installed on the base assembly 10, the flip gear is installed on the output end of the flip motor, and the material reversing belt is installed on the flip gear. Through the setting of the material reversing structure 41, the uniformity of the material arrangement of the carbon fiber chopped strands uniform distribution device is further improved. The above structure is compact and easy to operate. It should be noted that when in use, the gate is opened, and the material slides downward under the action of gravity. At this time, the material reversing belt moves under the drive of the material reversing belt driving roller, and the material is arranged on the material reversing belt along the width direction. After the material reversing belt evenly distributes the material, the flip motor rotates, and the flip gear rotates a certain angle on the rack, so that the material on the material reversing belt falls on the screen plate 421. When the flip motor rotates, the screen plate 421 moves under the action of the moving eccentric motor 422, so that the material can fall on the screen plate 421 more evenly.

[0037] like Figures 1 to 5 As shown, in the technical solution of this embodiment, the material pouring structure 41 also includes a material pouring mounting frame, a material pouring belt driving roller, a material pouring belt driven roller and a material pouring belt driving unit. The material pouring belt driving roller and the material pouring belt driven roller are rotatably mounted on both sides of the material pouring mounting frame, respectively. The material pouring belt is a closed circular ring. The material pouring belt driven roller and the material pouring belt driving roller are respectively braced on the inner wall of the material pouring belt. The material pouring belt driving unit is arranged on the material pouring mounting frame and is connected to the material pouring belt driving roller. The flipping motor is arranged on the material pouring mounting frame. The material pouring belt has a certain width, so that the material is not easy to fall outside the material pouring belt when it slides from the funnel 322. The above structure further improves the uniformity of material distribution, and the degree of automation of the carbon fiber chopped strand distribution device is further improved.

[0038] like Figure 5 and Figure 6As shown, in the technical solution of this embodiment, the vibrating screen structure 42 includes a sieve plate 421, a mobile eccentric motor 422, a connecting rod 423 and a limiting rod 424. The sieve plate 421 is movably arranged on the base assembly 10, the mobile eccentric motor 422 is arranged on the base assembly 10, the first end of the connecting rod 423 is rotatably connected to the eccentric shaft of the mobile eccentric motor 422, the second end of the connecting rod 423 is rotatably connected to the first end of the limiting rod 424, and the second end of the limiting rod 424 is connected to the sieve plate 421. The mobile eccentric motor 422 drives the connecting rod 423, the connecting rod 423 drives the limiting rod 424, and the limiting rod 424 drives the sieve plate 421 to move horizontally. The connecting rod 423 is divided into two sections, and the middle part of the connecting rod 423 has a rotating joint, so that the change of the connecting rod 423 in the height direction will not be transmitted to the limiting rod 424. In addition, a limiting sleeve is provided on the base assembly 10, and the limiting rod 424 is inserted into the limiting sleeve. It should be noted that there are two movable eccentric motors 422, connecting rods 423 and limiting rods 424, which are respectively provided on both sides of the sieve plate 421, and will not be described in detail here.

The setting of the long hole allows the boss and the long hole to have a certain degree of freedom, the width of the long hole is adapted to the diameter of the boss, and the length of the long hole is set corresponding to the eccentricity of the vibrating eccentric motor 425, which will not be repeated here. The long hole and the vibrating eccentric motor are respectively located on both sides of the screen plate body and are symmetrically arranged, so that the force of the screen plate body is relatively balanced. The rotation of the eccentric motor drives the movement and vibration of the screen plate body, so that the carbon fiber short chopped strands continuously change positions and fall from the screen plate holes more evenly.

[0040] like Figure 5 and Figure 6 As shown, in the technical solution of this embodiment, a plurality of sieve plate holes are arranged on the sieve plate 421, each sieve plate hole is larger than the carbon fiber chopped strands, and the plurality of sieve plate holes are arranged in a staggered manner. In this way, the carbon fiber chopped strands fall more evenly. The plurality of sieve plate holes are arranged in a staggered manner, which means that the adjacent sieve plate holes in the direction perpendicular to the width are arranged in a staggered manner, so that the material is spread more evenly.
