Description

Technical Field

[0001] This invention relates to the field of carbon fiber weaving tools, and particularly to a weaving platform for weaving the arm of a carbon fiber-woven drone. Background Technology

[0002] Carbon fiber refers to high-strength, high-modulus fibers with a carbon content of over 90%. It has the highest heat resistance among all chemical fibers. It is made from acrylic and viscose fibers. After carbon fiber is woven by a weaving device, it forms carbon fiber fabric. The existing carbon fiber weaving uses a gradient diameter capsule structure, which has poor heat and friction resistance, and it is difficult to change the diameter and thickness.

[0003] Chinese Patent CN 220643401 U discloses a carbon fiber weaving device, comprising: a weaving machine body, a limiting structure, a winding mechanism, and an electric roller. The limiting structure is fixed to one side of the weaving machine body, and includes two connecting plates and two movable sleeves. Connecting plates are symmetrically fixed to one side of the weaving machine body. Movable sleeves are fixed to the lower part of the side of the two connecting plates away from the weaving machine body, and the winding mechanism is movably connected within the two movable sleeves. An electric roller is located on the side of the weaving machine body away from the limiting structure, and a first side rod is fixed to one end of the electric roller. This invention, by setting up the weaving machine body, limiting structure, winding mechanism, and electric roller, solves the problems of wrinkles easily formed in the woven fibers due to different tensions during carbon fiber weaving, and the cumbersome operation of unwinding the woven fabric from the wound carbon fiber.

[0004] However, this device cannot accurately handle variations in diameter and thickness of the woven carbon fiber, thus requiring a weaving platform for the arm of a carbon fiber weaving drone to solve the aforementioned problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the friction during the weaving process is large, making it impossible to weave fabrics of different diameters and thicknesses, and requiring secondary processing.

[0006] To address the aforementioned technical problems, a weaving platform for carbon fiber weaving drone arms is proposed; this is achieved through the following technical solution:

[0007] It includes a platform frame, an shedding actuator, a fabric traction structure, a height adjustment structure, and a drive structure. The platform frame is placed on the ground, and the shedding actuator is suspended on the platform frame through multiple drive structures. The shedding actuator moves vertically relative to the platform frame. The shedding actuator includes an inner knitting frame for threading warp threads and an outer knitting frame for threading warp threads. The height adjustment structure is vertically set on the platform frame, and the fabric traction structure is set at the output end of the height adjustment structure. The height of the fabric traction structure is adjustable. Weft yarns are fitted on the fabric traction structure.

[0008] The height of the fabric traction structure can be adjusted by a height adjustment mechanism to ensure that the fabric traction structure remains at a suitable height during the weaving process, thus guaranteeing the weaving strength and smoothness of the entire structure. The fabric traction structure can be disassembled and replaced according to the diameter of the fabric to be woven, and the opening actuator can change the weaving thickness according to the weaving requirements, reducing the possibility of secondary processing.

[0009] In a preferred embodiment of the present invention, the platform frame is composed of several aluminum profiles with a square cross-section. The platform frame is used to install other structures to ensure the stability of the entire weaving platform.

[0010] In a preferred embodiment of the present invention, both the inner and outer woven frames include four woven sub-frames, which are connected end to end in a square shape. The inner woven frame is located inside the platform frame, and the outer woven frame is located outside the platform frame. The inner and outer woven frames repeatedly approach and move away from each other during the weaving process.

[0011] In a preferred embodiment of the present invention, both the inner and outer woven frames include four woven sub-frames, which are connected end to end in a square shape. The inner woven frame is located inside the platform frame, and the outer woven frame is located outside the platform frame, ensuring that the two frames can move up and down respectively.

[0012] In a preferred embodiment of the present invention, both the inner woven frame and the outer woven basket are slidably connected to the platform frame via guide members, and the inner woven frame and the outer woven basket repeatedly move closer and further apart to perform weaving.

[0013] In a preferred embodiment of the present invention, the height adjustment structure includes a first motor, a connecting rod, and a transmission structure. The first motor and the transmission structure are connected to two mounting rods. The output end of the first motor is connected to one end of the transmission structure, and the other end of the transmission structure is connected to the lower end of the connecting rod. The upper end of the connecting rod is connected to a fabric traction structure. The transmission structure drives the connecting rod to move up and down to adjust the height of the fabric traction structure.

[0014] In a preferred embodiment of the present invention, the transmission structure is a worm gear screw jack that drives the fabric traction structure to move up and down.

[0015] In a preferred embodiment of the present invention, the drive structure includes a second motor, a mounting frame, rollers, a transmission belt, and a connecting rope. Two mounting frames are installed on each of the four sides of the top of the platform frame. Multiple rollers are symmetrically arranged on both sides of the mounting frames. A second motor is connected to each side of the mounting frame. The output end of the second motor is connected to the bottom roller through a bevel gear transmission assembly. Multiple rollers installed on one side are connected in pairs through a transmission belt. A connecting rope is inserted through a set of symmetrically arranged rollers. The two ends of the connecting rope are respectively connected to the inner layer braided frame and the outer layer braided frame. The second motor drives the bottom roller to rotate, thereby changing the length of the connecting rope and controlling the up and down movement of the inner layer braided frame and the outer layer braided frame. When multiple sets of inner layer braided frames and outer layer braided frames are installed, the transmission belt drives multiple sliding rotations above, driving multiple connecting ropes to move and controlling the movement of multiple sets of inner layer braided frames and outer layer braided frames.

[0016] In a preferred embodiment of the present invention, a slot is provided in the middle of the top of the platform frame to prevent damage to the fabric traction structure from impact, thus preventing the upper end of the fabric traction structure from colliding with the top plate and causing damage to the fabric traction structure.

[0017] The advantages of this utility model compared with the prior art are:

[0018] 1. The height of the fabric traction structure is adjusted by the height adjustment structure to ensure that the fabric traction structure is kept at a suitable height during the weaving process, thus ensuring the weaving strength and smoothness of the entire structure during the weaving process.

[0019] 2. The fabric traction structure can be disassembled and replaced according to the diameter of the fabric to be woven, and the opening actuator can change the weaving thickness according to the weaving requirements, reducing the possibility of secondary processing.

[0020] 3. Reduce friction between the weaving platform and the weaving material to reduce the possibility of the platform being heated by friction and affecting the weaving process. Attached Figure Description

[0027] The following will refer to the appendix in the embodiments of this utility model. Figures 1-5 The technical solutions in the embodiments of this utility model will be described in detail below. Example

[0028] like Figure 1 , 2 As shown in Figures 3, 4, and 5, a weaving platform for a carbon fiber weaving drone arm includes a platform frame 1, an opening actuator 2, a fabric traction structure 4, a height adjustment structure 3, and a drive structure 5.

[0029] like Figure 1 As shown, the platform frame 1 is placed on the ground. The platform frame 1 is constructed by welding several aluminum profiles and has a square cross-section. The top of the platform frame 1 is fixedly connected to the drive structure 5 by screws. An opening actuator 2 is slidably connected to the platform frame 1. The opening actuator 2 is driven by the drive structure 5 to perform weaving.

[0030] The platform frame 1 includes four top rods 11 welded end to end, four vertical guide columns 12, and a mounting base 8. The four vertical guide columns 12 are welded to the four corners of the four top rods 11 welded end to end. The four vertical guide columns 12 are provided with sliding grooves. The opening actuator 2 is slidably connected to the four vertical guide columns 12 through guide members 61, so as to ensure that the guide members 61 can drive the opening actuator 2 to move vertically along the four vertical guide columns 12.

[0031] Four vertical guide posts 12 are evenly distributed on the same arc construction line with the center point of the loom as the center.

[0032] The mounting base 8 is welded to the lower center of the four vertical guide columns 12 to reserve installation space for the height adjustment structure 3.

[0033] The top center of the platform frame 1 has a hollow groove 7 to prevent the fabric traction structure 4 from being damaged by impact during operation, thus preventing operational errors from causing the fabric traction structure 4 to collide with the platform frame 1 and be damaged.

[0034] like Figure 1 As shown, a height adjustment structure 3 is fixedly installed on the mounting base 8 by screws. The adjustment structure 3 is installed in the middle position of the entire mounting base 8 to prevent the height adjustment structure 3 and the fabric traction structure 4 from being misaligned, which could cause problems with the woven fabric.

[0035] like Figure 1 and Figure 2 As shown, the height adjustment structure 3 includes a first motor 31, a connecting rod 32, and a transmission structure 33. The transmission structure 33 has two threaded connection holes on its two bottom sides. The transmission structure 33 and the first motor 31 are mounted on the mounting base 8 with screws. The output end of the first motor 31 is fixedly connected to the drive end of the transmission structure 33. The other end of the transmission structure 33 is connected to the connecting rod 32 through a flange. The upper end of the connecting rod 32 is connected to the fabric traction structure 4 with screws.

[0036] The first motor 31 drives the transmission structure 33 to move the connecting rod 32 and the fabric traction structure 4 up and down. During the weaving process, the warp and weft yarns start to weave from the top of the fabric traction structure 4. The first motor 31 controls the fabric traction structure 4 to move upward during the weaving process, so that the woven product wraps around the fabric traction structure 4 from top to bottom, ensuring that the weaving material can be wrapped around the fabric traction structure 4 during the weaving process.

[0037] In this application, the transmission structure 33 is a worm gear screw jack, which is existing technology.

[0038] Weft yarns are wound around the fabric traction structure 4, so that the woven finished product is wound around the fabric traction structure 4. Different sizes and shapes of fabric traction structures 4 can be replaced by removing the screws. The upper and lower diameters of the fabric traction structure 4 are different, which can realize the diameter change during the weaving process without secondary processing, and can achieve one-piece molding.

[0039] like Figure 1 and Figure 4 As shown, the four vertical guide columns 12 of the platform frame 1 are slidably connected to the opening actuator 2 for weaving. The top of the platform frame 1 is fixedly connected to multiple drive structures 5 by screws. The lower end of the drive structure 5 is attached to the opening actuator 2, driving the opening actuator 2 to move up and down.

[0040] The opening actuator 2 includes an inner braided frame 21 for threading warp threads and an outer braided frame 22 for threading warp threads. Both the inner braided frame 21 and the outer braided frame 22 include four braided sub-frames. The four braided sub-frames are welded together at the ends to form a square shape. The braided sub-frames are slidably mounted on the vertical guide post 12 via the guide member 61.

[0041] The repeated relative movements of the inner weaving frame 21 and the outer weaving frame 22 of the opening actuator 2 interweave the warp threads passing through the inner weaving frame 21 and the outer weaving frame 22 with the weft threads on the fabric traction structure 4, so that the woven fabric is wrapped around the fabric traction structure 4.

[0042] In this embodiment, each vertical guide post 12 is slidably connected to a guide member 61. The guide member 61 includes a right-angle slider 611, which is slidably engaged with a groove on the vertical guide post 12. An inner layer woven frame 21 or an outer layer woven frame 22 is welded onto the right-angle slider 611 to facilitate the up-and-down movement of the inner layer woven frame 21 or the outer layer woven frame 22 for weaving.

[0043] The thickness of the woven fabric can be changed by altering the number of warp threads passing through the inner weaving frame 21 and outer weaving frame 22 on the vertical guide post 12, thus reducing the possibility of secondary processing.

[0044] like Figure 1 and Figure 2 As shown, the drive structure 5 includes a second motor 51, a mounting bracket 52, a roller 53, a transmission belt 54, and a connecting rope 55. Two mounting brackets 52 are welded to each of the four top rods at the top of the platform frame 1. The mounting bracket 52 includes a bottom rod 521 and two mounting inclined frames 522. The two mounting inclined frames 522 are symmetrically installed at both ends of the bottom rod 521 by screws. The bottom rod 521 is welded to the four top rods at the top of the platform frame 1. In this embodiment, two mounting brackets 52 are welded to each top rod.

[0045] Rollers 53 are installed inside the mounting bracket 52. In this embodiment, three rollers 53 are installed in each mounting bracket 52 through bearings. The rollers 53 in two mounting brackets 52 correspond one-to-one in the horizontal direction. A second motor 51 is installed at the bottom of the mounting bracket 52. The second motor 51 drives the bottom roller 53 through a bevel gear transmission assembly. The three rollers 53 are connected in pairs through a transmission belt 54 to ensure that the rotation of the bottom roller 53 can drive the upper roller 53 to rotate together.

[0046] Each set of horizontal rollers 53 is equipped with a connecting rope 55. One end of the connecting rope 55 is tied to the inner woven frame 21, and the other end of the connecting rope 55 is tied to the outer woven frame 22. This ensures that when the inner woven frame 21 moves down, the outer woven frame 22 moves up, so that the inner woven frame 21 and the outer woven frame 22 can achieve a repetitive motion of first moving closer and then moving further apart.

[0047] When it is necessary to change the weaving thickness, the number of right-angle sliders 611 and inner weaving frames 21 and outer weaving frames 22 that are slidably connected on the vertical guide post 12 can be changed without secondary processing.

[0048] How to use:

[0049] First, install a suitable fabric traction structure 4 according to the requirements. During the weaving process, the drive structure 5 drives the fabric traction structure 4 to move up and down. When the opening actuator 2 opens, the inner weaving frame 21 and the outer weaving frame 22 move vertically. The opening actuator 2 forms a warp opening. The warp yarns come into contact with the weft yarn of the loom through the opening movement of the opening actuator 2 and interweave. The woven fabric is wrapped around the fabric traction structure 4 to form a fabric with an adjustable diameter. This method is easy to operate, the forming thickness can be adjusted, and it can be formed in one piece.

[0050] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
