Description

Technical Field

[0001] This utility model relates to a fiber bundle tube fixing structure, and in particular to a glass fiber bundle tube rotating clamping structure. Background Technology

[0002] Prepreg tape is a strip-shaped composite intermediate material made by pre-impregnating a resin system with reinforcing fibers such as glass fiber. It originated from the mid-20th century aerospace field's demand for high-performance, repeatable composite materials. Its development is mainly based on the automation of resin formulation and process from thermosetting to thermoplastic. In terms of performance, it has advantages such as high specific strength, high specific modulus, strong designability and fatigue resistance, and is a key material for achieving lightweight structures.

[0003] In the prior art, for the convenience of transportation and use, the fibers are usually fixed on the yarn bobbin. The applicant previously filed a Chinese utility model patent with application number 202421435677.3, entitled Glass Fiber Feeding Guiding Structure. The yarn bobbin is usually fixed on the rotating roller. In order to tension the rotating roller, manual adjustment is usually required, which makes it impossible to quickly install and remove the yarn bobbin. Utility Model Content

[0004] The purpose of this invention is to provide a glass fiber bundle tube rotary clamping structure, which has the advantages of precise installation and positioning and convenient loading and unloading.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a glass fiber bundle tube rotary clamping structure, comprising an intermediate shaft, a limiting plate provided at one end of the intermediate shaft along its length, and an air inlet provided at the other end of the intermediate shaft along its length. An intermediate cylinder, a movable plate, and a fixed plate are sequentially arranged on the intermediate shaft. A limiting structure is provided on the intermediate shaft to limit the maximum distance between the limiting plate and the fixed plate. The intermediate cylinder and the movable plate are slidably connected axially on the intermediate shaft. The two ends of the intermediate cylinder along its axial direction are respectively connected to the limiting plate. A deformation cavity is formed between the movable plate and the fixed plate. The side of the deformation cavity closest to the intermediate cylinder is a conical surface. The conical surfaces are respectively set at both ends of the intermediate cylinder in the axial direction. A spring connected end to end is arranged around the circumference of each deformation cavity. A sliding sealing cavity is formed between the movable plate and the fixed plate. The air inlet extends into the sliding sealing cavity. After the air inlet supplies air to the sliding sealing cavity, the movable plate moves towards the intermediate cylinder, causing the spring to expand outward along the conical surface. After the air supply stops, the spring returns inward, causing the spring to contract inward along the conical surface and reset the movable plate.

[0006] Preferably, the limiting plate, the fixing plate, and the movable plate are circular, and the limiting plate, the fixing plate, and the movable plate are provided with mating holes for the intermediate shaft to pass through.

[0007] By adopting the above technical solution, the limiting plate, fixed plate and movable plate form a circular restraining spring to disengage, and the matching holes ensure accurate alignment of the components and convenient installation.

[0008] Preferably, the limiting structure restricts the limiting plate and the fixing plate from moving outward along the axial direction of the intermediate axis.

[0009] By adopting the above technical solution, the limiting structure effectively prevents the axial movement of the limiting plate and the fixing plate, and improves the stability of the clamping.

[0010] Preferably, the limiting structure includes a threaded hole, a tail washer, and a limiting bolt. The threaded hole is located at the end of the intermediate shaft, the tail washer is located on the outward side of the limiting plate, the tail washer is larger than the diameter of the mating hole, and the limiting bolt passes through the tail washer and connects to the threaded hole.

[0011] The limiting plate is fixed by adopting the above technical solution.

[0012] Preferably, the limiting structure includes a circumferential step, which is disposed on the intermediate shaft and is concentric with the intermediate shaft. The diameter of the circumferential step is larger than the diameter of the intermediate shaft and the diameter of the mating hole, and one side of the circumferential step is in contact with the outward side of the fixing plate.

[0013] By adopting the above technical solution, the limiting plate and its subsequent components are effectively limited.

[0014] Preferably, the intermediate cylinder includes a left cover plate, a PVC sleeve, and a right cover plate. The mating hole is located at the center of the left and right cover plates. A stepped groove is provided at one end of the outer circumference of the left and right cover plates facing inward. The two ends of the PVC sleeve in the axial direction mate with the stepped groove. The outer circumferential surface of the PVC sleeve is flush with the outer circumferential surface of the left and right cover plates.

[0015] By adopting the above technical solution, materials are saved, the overall weight is simplified, subsequent rotation is facilitated, and the inertia generated during rotation is reduced.

[0016] Preferably, the left and right cover plates extend outward to form a first abutting end, and the movable plate and the limiting plate are provided with a second abutting end that mates with the first abutting end. A nylon gasket is provided between the first abutting end and the second abutting end. The mating hole passes through the first abutting end and the second abutting end. The outer sides of the left and right cover plates are recessed along the axial direction to form a first annular groove, and the limiting plate and the movable plate are recessed along the axial direction to form a second annular groove.

[0017] By adopting the above technical solution, the impact between metal materials after the spring retracts can be avoided.

[0018] Preferably, the tapered surface extends axially outward at the ends of the left and right cover plates to form a horizontal section.

[0019] By adopting the above technical solution, the length of the horizontal section ensures that the spring remains in a retracted state without pressure.

[0020] Preferably, the sliding sealing cavity is disposed on the circumferential end face of the fixed plate, and the movable plate is provided with an annular sliding protrusion that mates with the sliding sealing cavity. The inner circumferential side surface and outer circumferential side surface of the annular sliding protrusion and the mating hole of the fixed plate are all provided with sealing grooves and sealing rings. The nylon gasket is disposed between the annular sliding protrusion and the sliding sealing cavity.

[0021] By adopting the above technical solution, after air enters through the air inlet, pressure is applied in the sliding sealing cavity, which pushes the annular sliding protrusion to move, expands the spring, and then fixes the fiber sleeve. The sealing groove and sealing ring cooperate to achieve the sealing function.

[0022] In summary, compared with the existing technology of manually controlling the mechanical structure to open, by injecting air pressure into the intermediate shaft, the air pressure controls the moving plate to move towards the intermediate cylinder, and then under the action of the conical surface, the spring opens to achieve automatic clamping. After the air is exhausted, the fiber tube is released under the elastic recovery of the spring. The operation is simpler and the clamping efficiency is improved. The opening and closing of the spring on the conical surface provides uniform clamping force, ensuring that the glass fiber bundle tube is fixed and the fixing effect is good.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0030] Example:

[0031] like Figures 1 to 4 As shown, a glass fiber bundle tube rotary clamping structure includes an intermediate shaft 1, which serves as a fixing component. A limiting plate 2 is provided at one end of the intermediate shaft 1 along its length, and an air inlet 11 is provided at the other end of the intermediate shaft 1 along its length. The air inlet 11 extends into the intermediate shaft 1 for a certain length and serves to maintain pressure. An intermediate tube 3, a movable plate 41, and a fixed plate 42 are sequentially arranged behind the limiting plate 2 on the intermediate shaft 1. The intermediate shaft 1 corresponds to the fiber tube. The movable plate 41 and the fixed plate 42 cooperate to open the spring 23 and fix the fiber tube. A limiting structure is provided on the intermediate shaft 1 to limit the maximum distance between the limiting plate 2 and the fixed plate 42. The intermediate tube 3 and the movable plate 41 are slidably connected in the axial direction of the intermediate shaft 1.

[0032] like Figure 3 As shown, deformation cavities 22 are formed between the two ends of the intermediate cylinder 3 and the limiting plate 2 and the fixed plate 42, respectively. When the movable plate 41 moves, the deformation cavities 22 located on the left and right sides of the intermediate cylinder 3 deform synchronously under the action of the spring 23. The side of the deformation cavity 22 closest to the intermediate cylinder 3 is a conical surface 31. The conical surfaces 31 are respectively set at the two ends of the intermediate cylinder 3 in the axial direction. The conical surfaces 31 extend outward along the axial direction at the ends of the left cover plate 33 and the right cover plate 35 to form horizontal sections 32. Each deformation cavity 22 is circumferentially surrounded by springs 23 connected end to end. A sliding sealing cavity 4 is formed between the movable plate 41 and the fixed plate 42. The air inlet 11 extends into the sliding sealing cavity 4. After the air inlet 11 supplies air to the sliding sealing cavity 4, the movable plate 41 moves towards the intermediate cylinder 3, causing the spring 23 to expand outward along the conical surface 31. After the air supply stops, the spring 23 returns inward, causing the spring 23 to contract inward along the conical surface 31 and the movable plate 41 to reset.

[0033] like Figure 2 and Figure 3 As shown, the specific structure of the limiting plate 2, the fixed plate 42 and the movable plate 41 is as follows: the limiting plate 2, the fixed plate 42 and the movable plate 41 are circular, and the limiting plate 2, the fixed plate 42 and the movable plate 41 are provided with mating holes 21 for the intermediate shaft 1 to pass through.

[0034] like Figure 2 and Figure 3 As shown, in this embodiment, the limiting structure restricts the limiting plate 2 and the fixing plate 42 from moving outward along the axial direction of the intermediate shaft 1. Therefore, the specific structure and method of the fiber structure are as follows: the limiting structure of the limiting plate 2 includes a threaded hole 51, a tail washer 52 and a limiting bolt 53. The threaded hole 51 is located at the end of the intermediate shaft 1, the tail washer 52 is located on the outward side of the limiting plate 2, the tail washer 52 is larger than the diameter of the mating hole 21, and the limiting bolt 53 passes through the tail washer 52 and connects to the threaded hole 51.

[0035] like Figure 2 and Figure 3 As shown, the limiting structure at the position of the fixed plate 42 includes a circumferential step 54, which is set on the intermediate shaft 1 and is concentric with the intermediate shaft 1. The diameter of the circumferential step 54 is larger than the diameter of the intermediate shaft 1 and the diameter of the mating hole 21. One side of the circumferential step 54 is in contact with the outward side of the fixed plate 42. Therefore, the fixed plate 42, the movable plate 41 and the limiting plate 2 are installed through the outward end of the intermediate shaft 1.

[0036] like Figure 3 As shown, in order to simplify the weight, the weight will generate a large inertia during the rotation process. Because it is necessary to ensure stable tension, the large inertia will cause the fiber thread to go out. Therefore, the intermediate cylinder 3 adopts a structure with extreme weight reduction. That is, the intermediate cylinder 3 includes a left cover plate 33, a PVC sleeve 34 and a right cover plate 35. The mating hole is set at the center of the left cover plate 33 and the right cover plate 35. The outer circumference of the left cover plate 33 and the right cover plate 35 is provided with a stepped groove at one end. The two ends of the PVC sleeve 34 in the axial direction are engaged with the stepped groove. The outer circumference of the PVC sleeve 34 is flush with the outer circumference of the left cover plate 33 and the right cover plate 35. The intermediate cylinder 3 is formed by clamping the PVC sleeve 34 with the left and right cover plates 35.

[0037] like Figure 3 As shown, in order to reduce the impact when spring 23 retracts, and to adjust the gap between the two,

[0038] The left cover plate 33 and the right cover plate 35 extend outward to form a first abutting end 36. The movable plate 41 and the limiting plate 2 are provided with a second abutting end 24 that cooperates with the first abutting end 36. A nylon gasket 25 is provided between the first abutting end 36 and the second abutting end 24. The mating hole 21 is provided through the first abutting end 36 and the second abutting end 24. The outer sides of the left cover plate 33 and the right cover plate 35 are recessed along the axial direction to form a first annular groove 37. The limiting plate 2 and the movable plate 41 are recessed along the axial direction to form a second annular groove 26.

[0039] like Figure 3 and Figure 4As shown, the specific structure of the sliding sealing cavity 4 is as follows: the sliding sealing cavity 4 is set on the circumferential end face of the fixed plate 42, and the movable plate 41 is provided with an annular sliding protrusion 43 that cooperates with the sliding sealing cavity 4. The inner circumferential side surface, the outer circumferential side surface of the annular sliding protrusion 43 and the mating hole 21 of the fixed plate 42 are all provided with sealing grooves 44 and sealing rings 45. The nylon gasket 25 is provided between the annular sliding protrusion 43 and the sliding sealing cavity 4.

[0040] Working principle:

[0041] High-pressure gas is injected into the intermediate shaft 1 through the factory gas pipe. The high-pressure gas enters the sliding sealing cavity 4, which in turn pushes the annular sliding protrusion 43 to move outward within the sliding sealing cavity 4. Since the annular sliding protrusion 43 is integrated with the movable plate 41, the high-pressure gas controls the movable plate 41 to move towards the intermediate cylinder 3. Under the action of the conical surfaces 31 on both sides, the spring 23 deforms outward along the radial direction of the intermediate cylinder 3, protruding from the circumferential side of the intermediate cylinder 3, thereby automatically clamping the outer fiber tube. At the same time, after exhausting the gas, that is, after the high-pressure gas is discharged from the sliding sealing cavity 4, the spring 23 deforms inward to restore its shape, synchronously controlling the movable plate 41 to move outward, thereby releasing the fiber tube.
