Description

Technical Field

[0001] The invention relates to a composite material weaving technology, in particular to a hexagonal honeycomb three-dimensional weaving device and a weaving method thereof. Background Art

[0002] With the continuous advancement of industrial technology, existing materials can no longer fully meet the functional requirements of industrial equipment. Therefore, three-dimensional woven materials with higher toughness, lighter weight and stronger pressure-bearing capacity are gradually becoming the first choice for modern industrial production.

[0003] However, the current three-dimensional weaving technology is not advanced enough. Most machines that weave three-dimensional bodies have poor error tolerance. Generally, small errors cannot be adjusted in time, but gradually accumulate until the machine is damaged and cannot move. Moreover, most braided bodies have a monotonous force direction, a complex weaving structure, and a slow weaving speed. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a hexagonal honeycomb three-dimensional weaving device and a weaving method thereof with reasonable design, good toughness and high production efficiency.

[0005] The technical solution of the present invention is: A hexagonal honeycomb three-dimensional weaving device, comprising weaving monomers, the weaving monomers are arranged in the shape of a regular hexagon to form a square array combination, the weaving monomers include a supporting platform, a rotating disc and a yarn carrier, the rotating disc is arranged on the supporting platform and the two are rotatably matched, three rotating gears and guide rails are evenly distributed along the circumference on the upper end surface of the rotating disc, a slider is arranged on the guide rail, the slider is connected to the rotating gear through a connecting rod, the yarn carrier is connected to the guide rail through a guide rail groove, and an outer gear ring is arranged on the lower end surface of the rotating disc; A rotating shaft is arranged at the center of the rotating disc, a central gear is arranged at the upper end of the rotating shaft, the central gear is meshed with the three rotating gears at the same time, and a driven gear is arranged at the lower end of the rotating shaft; The outer gear ring and the driven gear are respectively connected to the driving motor to realize respective rotation to weave the silk thread.

[0006] Furthermore: all the outer gear rings on the rotating disc are connected together by a set of transmission belts, and the outermost one of the outer gear rings is also connected to the outer gear ring drive motor; all the driven gears are connected together by another set of transmission belts, and the outermost one of the driven gears is also connected to the driven gear drive motor.

[0007] Furthermore: all the outer gear rings on the rotating disc are connected together through a set of intermediate transition gears, and finally connected to the outer gear ring drive motor; all the driven gears are connected together through another set of intermediate transition gears, and finally connected to the driven gear drive motor.

[0008] Furthermore: the supporting platform is a regular hexagon, and a center step shaft hole is arranged on its upper end face, the rotating disc is located at the upper part of the center step shaft hole, and the outer gear ring extends from the lower part of the center step shaft hole; a channel is arranged on the upper hole wall of the center step hole to facilitate the passage of the yarn carrier.

[0009] Furthermore, the end face of the guide rail is a T-shaped structure, a thread post is arranged at the upper end of the yarn carrier, and the guide rail groove at the lower end is also a T-shaped structure.

[0010] Furthermore, the supporting platform, the rotating disc and the yarn carrier are respectively made of aluminum alloy or ABS engineering plastics, so as to reduce the friction of the slide rail during the exchange.

[0011] Furthermore: there is no contact between adjacent support platforms or between the support platform and the rotating disc, and there is a gap between the two, and the gap is no greater than the width of the yarn carrier, so as to prevent the yarn carrier from falling.

[0012] A hexagonal honeycomb three-dimensional weaving method using the hexagonal honeycomb three-dimensional weaving device comprises the following steps: (1) First, select the number of braided units as required and arrange them in formation, then connect the outer gear ring and the driven gear to the drive motor respectively, and finally, start the drive motor; (2) The rotating disc drives the yarn carrier to rotate 240° to make the yarn knotted. During the rotation of the rotating disc, the driven gear on the lower layer rotates at the same speed to ensure that the central gear and the rotating disc are relatively stationary to prevent the slider from moving; (3) The outer gear ring of the upper layer is stationary, and the driven gear of the lower layer continues to rotate 360°, driving the rotating gear to rotate through the central gear, thereby driving the connecting rod to move. The connecting rod drives the slider to move outward and reach the maximum distance, pushing the yarn carrier into the slide rail on the adjacent rotating disc; (4) The rotating disc starts to rotate, and the driven gear on the lower layer starts to rotate at the same speed, keeping relatively still with the rotating disc. The rotating disc rotates 240° and then stops again; (5) The outer gear ring on the upper layer is stationary, and the driven gear on the lower layer continues to rotate 180°, driving the connecting rod to move outward to the maximum distance through the central gear and the driving gear, pushing the yarn carrier into the slide rail of the next rotating disc; (6) Repeat the above steps for the sixth time. The yarn carrier returns to its original position and the above operation can be continued to complete the weaving.

[0013] Further: This structure consists of three yarns distributed outside the central axis at an interval of 120° and spirally wound around each other at 240°. The yarns between the starting points are 120° apart, and rotate 240° around the center of the wheel, so the yarns between the end points are 120° apart, thus forming a structural monomer.

[0014] Furthermore: when the yarn completes a unit, the first unit is assumed to be the first layer. After the first layer is woven, the yarn carrier is pushed into the next wheel to start the second round of weaving. It rotates 240° around the center of the wheel. When the second round ends, the benzene shape is formed. Moreover, in the overall structure, the arrangement between the yarns is such that each 240-degree rotation of the yarn carrier is regarded as a layer. When weaving enters the odd-numbered layers, the yarn carrier is pushed back by the outer slider. At this time, the yarn carrier on the outer layer of the even-numbered layers does not move, so it presents a cylindrical shape.

[0015] The beneficial effects of the present invention are: 1. The present invention consists of three yarns distributed outside the central axis at an interval of 120° and spirally wound around each other at 240°. The yarns between the starting points are 120° apart and rotate 240° around the center of the wheel, so the yarns between the end points are 120° apart, thereby forming a structural monomer. The structural monomers are staggered and connected to form a hexagonal honeycomb shape, which can effectively withstand forces from multiple directions and improve the comprehensive performance of the material.

[0016] 2. The present invention can ensure the regularity and consistency of the movement of the yarn carrier by setting the guide rail, prevent deviation, and improve the weaving effect.

[0017] 3. The present invention adopts a crank-connecting rod structure, which can periodically push the yarn carrier to move back and forth, and can participate in the weaving of adjacent different rotating discs with good consistency.

[0018] 4. In the present invention, the outer gear ring and the driven gear are connected in series respectively, and each layer is connected by an intermediate transition gear or a transition toothed belt. Finally, each layer is driven by a driving motor to achieve the purpose of unified rotation.

[0019] 5. The present invention has reasonable design, good toughness and high production efficiency, and can be applied to a variety of industrial applications, especially in fields requiring high-strength and multifunctional force support. It shows its unique advantages and application potential, and has good economic benefits after promotion. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] A hexagonal honeycomb three-dimensional weaving device, comprising weaving monomers, wherein: the weaving monomers are arranged in the shape of a regular hexagon to form a square array combination, the weaving monomers include a support platform 1, a rotating disc 2 and a yarn carrier 3, the rotating disc 2 is arranged on the support platform 1 and the two are rotatably matched, three rotating gears 12 and a guide rail 15 are evenly distributed along the circumference on the upper end surface of the rotating disc 2, a slider 14 is arranged on the guide rail 15 (the two are slidably connected, guided and slid), the slider 14 is connected to the rotating gear 12 through a connecting rod 13 (the connection here is all rotatably connected, can rotate, and constitute a crank connecting rod mechanism), the yarn carrier 3 is connected to the guide rail 15 through a guide rail groove 9 (the two are slidably connected, guided and slid), and an outer tooth ring 7 is arranged on the lower end surface of the rotating disc 2; A rotating shaft 10 is disposed at the center of the rotating disk 2, a central gear 5 is disposed at the upper end of the rotating shaft 10, the central gear 5 is meshed with three rotating gears 12 at the same time, and a driven gear 11 is disposed at the lower end of the rotating shaft 10; All the outer gear rings 7 on the rotating discs 2 are connected together through a set of transmission toothed belts 4, and the outermost outer gear ring 7 is also connected to the outer gear ring drive motor (not shown in the figure); all the driven gears 11 are connected together through another set of transmission toothed belts 4, and the outermost driven gear 11 is also connected to the driven gear drive motor (not shown in the figure). Such a drive motor can drive a layer of outer gear rings 7 or driven gears 11 to rotate. Of course, the outer gear rings 7 and driven gears 11 can be made to have a certain thickness and can be connected to several transmission toothed belts 4 at the same time.

[0023] Preferred solution: the supporting platform 1 is a regular hexagon, and a center step shaft hole is arranged on its upper end face. The rotating disc 2 is located at the upper part of the center step shaft hole, and the outer gear ring 7 extends from the lower part of the center step shaft hole; a channel 6 is arranged on the upper hole wall of the center step hole to facilitate the passage of the yarn carrier 3.

[0024] Optimal solution: the end face of the guide rail 15 is a T-shaped structure, a thread post 8 is provided at the upper end of the yarn carrier 3, and the guide rail groove 9 at the lower end is also a T-shaped structure.

[0025] Optimal solution: the supporting platform 1, the rotating disc 2 and the yarn carrier 3 are respectively made of aluminum alloy or ABS engineering plastics to reduce the friction of the slide rail during exchange.

[0026] Optimal solution: There is no contact between adjacent support platforms 1 or between the support platform 1 and the rotating disk 2, and there is a gap between the two. The gap is no greater than the width of the yarn carrier 3 to prevent the yarn carrier 3 from falling.

[0027] The weaving method is as follows: (1) First, select the number of braided monomers as needed and arrange them in formation, then connect the outer gear ring 7 and the driven gear 11 to the drive motor respectively, and finally start the drive motor; (2) The rotating disc 2 drives the yarn carrier 3 to rotate 240° to make the yarn knotted. During the rotation of the rotating disc 2, the lower driven gear 11 rotates at the same speed to ensure that the central gear 5 and the rotating disc 2 are relatively stationary to prevent the slider from moving.

[0028] (3) The outer gear ring 7 on the upper layer is stationary, and the driven gear 11 on the lower layer continues to rotate 360 ​​degrees, driving the rotating gear 12 to rotate through the central gear 5, thereby driving the connecting rod 13 to move. The connecting rod 13 drives the slider 14 to move outward and reach the maximum distance, pushing the yarn carrier 3 into the slide rail 15 on the adjacent rotating disk 22.

[0029] (4) The rotating disc 2 starts to rotate. At this time, the driven gear 11 on the lower layer starts to rotate at the same speed, keeping relatively still with the rotating disc 2. The rotating disc 2 rotates 240° and then stops again.

[0030] (5) The outer gear ring 7 of the upper layer is stationary, and the driven gear 11 of the lower layer continues to rotate 180°, driving the connecting rod 13 to move outward to the maximum distance through the central gear 5 and the driving gear 12, pushing the yarn carrier 3 into the slide rail 15 of the next rotating disc 2.

[0031] (6) Repeat the above steps for the sixth time, and the yarn carrier 6 returns to its original position, and the above operation can be continued.

[0032] When the yarn has completed a unit, the first unit is assumed to be the first layer. After the first layer is completed, the yarn carrier is pushed into the next wheel to start the second round of weaving. It rotates 240° around the center of the wheel. When the second round is finished, the benzene shape is formed. In addition, in the overall structure, the arrangement of the yarns is such that each 240-degree rotation of the yarn carrier is regarded as a layer. When weaving enters the odd-numbered layers, the yarn carrier is pushed back by the outer slider. At this time, the yarn carrier on the outer layer of the even-numbered layers does not move, so it presents a cylindrical shape.

[0033] The structural advantages of the textile thread of the present invention are: 1. Anisotropy: The three-dimensional hexagonal honeycomb structure has significant differences in mechanical properties in different directions, that is, it has anisotropy. This means that the mechanical properties of the material in different directions are different, resulting in superior mechanical properties in the vertical direction.

[0034] 2. Strong adaptability: The hexagonal structure can be designed and adjusted as needed to meet different mechanical performance requirements, such as by changing the size, thickness or material properties of the hexagon.

[0035] 3. High strength and light weight: The hexagonal structure can effectively disperse the force applied to the material, so that under the same area and material usage, the hexagonal fabric can provide higher strength and stability. At the same time, due to the characteristics of the hexagonal structure, the material can be lightweight, which is particularly important for aerospace, military equipment and other fields.

[0036] 4. Shock absorption performance: The hexagonal structure can absorb shock to a certain extent and has a good effect on reducing vibration and noise.

[0037] Embodiment 2: This embodiment is basically the same as Embodiment 1, and the similarities are not repeated. The difference is that: the outer gear rings on all the rotating discs are connected together through a set of intermediate transition gears, and finally connected to the outer gear ring drive motor; all the driven gears are connected together through another set of intermediate transition gears, and finally connected to the driven gear drive motor.

[0038] Embodiment 3: This embodiment is basically the same as Embodiment 1, and the similarities are not repeated. The difference is that the outer gear ring and the transmission gear are not connected together through an intermediate transition gear or a transmission belt, but are connected to the drive motor separately. This solution is suitable for small square arrays.

[0039] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification made according to the technical essence of the present invention still falls within the scope of the technical solution of the present invention.
