Description

Technical Field

[0001] This utility model relates to the field of glass fiber fabric processing technology, specifically to a uniaxial pre-stretched structure for glass fiber fabric. Background Technology

[0002] Fiberglass fabric is a type of fabric made from fine glass fiber yarns. Due to its insulation, heat resistance, and high strength, it is widely used in various fields. However, the manufacturing process of fiberglass fabric often requires a uniaxial pre-stretching structure. By pre-stretching the fiberglass fabric unidirectionally using pre-support components, the unidirectional glass fibers can be straightened, thereby improving the mechanical properties of hand lay-up products. However, existing uniaxial pre-stretching structures for fiberglass fabric have some shortcomings, such as:

[0003] Existing uniaxial pre-stretching structures for glass fiber fabrics often make it difficult to synchronously pre-stretch multiple groups of fiber filaments or fiber fabrics. This may lead to problems such as inconsistent fiber usage or inconsistent fiber fabric thickness during the manufacturing process, affecting the quality and efficiency of the fiber fabric during manufacturing.

[0004] Therefore, we propose a uniaxial pre-stretched structure for glass fiber fabric to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a uniaxial pre-stretching structure for glass fiber fabrics, in order to solve the problem mentioned in the background art that the current uniaxial pre-stretching structures for glass fiber fabrics on the market often have difficulty in synchronously pre-stretching multiple groups of fiber filaments or the fiber fabric body.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a uniaxial pre-stretched structure for glass fiber fabric, comprising a device frame and a fiber roller installed inside the device frame, wherein a fiber fabric body is stretched on the outside of the fiber roller;

[0007] A combing mechanism is installed on the top of the device frame, and the combing mechanism includes a stretching roller, and a combing roller is provided on the top of the stretching roller. The fiber fabric body is wrapped around the outside of the stretching roller, and the combing roller is in contact with the surface of the fiber fabric body. The fiber fabric body moves to the left under the straightening of the stretching roller.

[0008] The device frame is equipped with a device shell on top, and a smoothing mechanism is provided at the left end of the device shell. The smoothing mechanism includes two sets of squeezing rollers, and the fiber fabric body is located between the two sets of squeezing rollers. The two sets of squeezing rollers can drive the fiber fabric body to move to the left.

[0009] By synchronously driving the combing mechanism and the smoothing mechanism through the drive mechanism, the stretching roller in the combing mechanism can be in contact with the surface of the fiber fabric body when it moves the fiber fabric body to the left in a single axial direction, thereby preventing the fiber fabric body from getting tangled. Subsequently, the two sets of extrusion rollers in the smoothing mechanism extrude and smooth multiple sets of fiber fabric bodies, so that the fiber fabric body will not have problems with deviation or inconsistent straightening and stretching length when it is pre-stretched in a single axis.

[0010] As a preferred technical solution of this utility model, a driving mechanism is provided inside the device housing, and the driving mechanism includes a driving motor, and a driving rod is connected to the driving end of the driving motor. A first bevel gear set and a second bevel gear set are provided on the outside of the driving rod.

[0011] The above technical solution enables the drive mechanism to operate more stably when driving the combing mechanism and the smoothing mechanism synchronously, thereby increasing the stability of the equipment during operation.

[0012] As a preferred technical solution of this utility model, the front end of the first bevel gear set is provided with a first driving gear, and the top of the first driving gear is meshed with a first driven gear, and the front ends of the first driving gear and the first driven gear are respectively connected to a set of extrusion rollers.

[0013] The above technical solution enables the meshing transmission of the first driving gear and the first driven gear, driving the two sets of extrusion rollers to rotate in opposite directions, and simultaneously extruding and smoothing multiple sets of fiber fabric bodies, thereby increasing the smoothing efficiency of the equipment on the fiber fabric body.

[0014] As a preferred technical solution of this utility model, the first driven gear is rotatably connected to the inside of the device housing through a bearing seat, and the front end of the second bevel gear set is connected to the second driving gear, and the top of the second driving gear is meshed with the second driven gear. The front end of the second driving gear is fixedly connected to the stretching roller, and the front end of the second driven gear is fixedly connected to the combing roller.

[0015] The above technical solution enables the bearing housing to support the driven gear and reduce rotational wear; the meshing transmission between the second driving gear and the second driven gear drives the stretching roller and the combing roller to rotate synchronously; the traction effect of the stretching roller realizes precise uniaxial stretching of the fiber fabric body; and the contact between the combing roller and the fabric surface can comb and entangle the fibers.

[0016] As a preferred technical solution of this utility model, the second driven gear is rotatably connected to the inside of the device housing through a bearing seat, and a fixed frame is provided on the top of the device frame, and the device frame is rotatably connected to the stretching roller and the combing roller through the fixed frame.

[0017] The above technical solution enables the fixing frame to provide stable support for the stretching roller and the combing roller, preventing the roller shaft from tilting; the rotary connection design ensures smooth operation of the roller shaft, and the lubrication effect of the bearing seat further reduces wear; and the modular design of the fixing frame facilitates the disassembly and maintenance of the roller shaft.

[0018] As a preferred technical solution of this utility model, a limiting hole is provided at the right end of the fixing frame, and the fiber fabric body passes through the limiting hole and wraps with the stretching roller.

[0019] The above technical solution enables the limiting holes to accurately guide the fiber fabric body and prevent deviation before stretching; the chamfered edge design of the limiting holes avoids scratching the fabric edge; and multiple fiber fabric bodies can be fed synchronously through the corresponding limiting holes to ensure that the stretching starting point of each structure is consistent, further improving the stretching uniformity.

[0020] As a preferred technical solution of this utility model, a limiting roller is installed on the top of the device frame, and the limiting roller is located between the extrusion roller and the stretching roller, and the limiting roller can guide the fiber fabric body.

[0021] The above technical solution enables the limiting roller to provide secondary guidance to the stretched fiber fabric body, avoiding displacement between the stretching and smoothing processes. Furthermore, the position design of the limiting roller can buffer fabric tension fluctuations and prevent fiber breakage caused by excessive stretching. The guiding effect ensures that the fabric enters the squeezing roller smoothly.

[0022] Compared with the prior art, the beneficial effects of this utility model are: by driving the combing mechanism and the smoothing mechanism to run synchronously through the drive mechanism, the stretching roller in the combing mechanism can be in contact with the surface of the fiber fabric body when it drives the fiber fabric body to move uniaxially to the left, thereby preventing the fiber fabric body from getting tangled. Subsequently, the two sets of extrusion rollers in the smoothing mechanism extrude and smooth multiple sets of fiber fabric bodies, so that the fiber fabric body will not have the problem of deviation or inconsistent straightening and stretching length when it is pre-stretched uniaxially.

[0023] Furthermore, by setting up the second driving gear and the second driven gear, the bearing seat can support the driven gear and reduce rotational wear; the meshing transmission of the second driving gear and the second driven gear drives the stretching roller and the combing roller to rotate synchronously. The traction effect of the stretching roller realizes the precise uniaxial stretching of the fiber fabric body, and the contact between the combing roller and the fabric surface can comb the entangled fibers.

[0024] Furthermore, by setting the limiting roller, the limiting roller can provide secondary guidance to the stretched fiber fabric body, avoiding displacement between the stretching and smoothing processes. In addition, the position design of the limiting roller can buffer fabric tension fluctuations and prevent fiber breakage caused by excessive stretching; the guiding effect ensures that the fabric enters the squeezing roller smoothly.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0033] Example 1: To address the problem that existing uniaxial pre-stretching structures for glass fiber fabrics often struggle to simultaneously pre-stretch multiple groups of fiber filaments or the entire fabric body, the following solution is disclosed. Please refer to [link / reference]. Figures 1-6 This utility model provides a technical solution: a uniaxial pre-stretched structure for glass fiber fabric, including a device frame 1 and a fiber roller 3 installed inside the device frame 1, wherein a fiber fabric body 4 is stretched on the outside of the fiber roller 3.

[0034] A combing mechanism is installed on the top of the device frame 1, and the combing mechanism includes a stretching roller 14, and a combing roller 15 is provided on the top of the stretching roller 14. The fiber fabric body 4 is wrapped around the outside of the stretching roller 14, and the combing roller 15 is in contact with the surface of the fiber fabric body 4. The fiber fabric body 4 moves to the left under the straightening of the stretching roller 14.

[0035] The device frame 1 is equipped with a device shell 2 on the top, and a smoothing mechanism is provided at the left end of the device shell 2. The smoothing mechanism includes two sets of squeezing rollers 10. The fiber fabric body 4 is located between the two sets of squeezing rollers 10, and the two sets of squeezing rollers 10 can drive the fiber fabric body 4 to move to the left.

[0036] The device housing 2 is equipped with a drive mechanism, which includes a drive motor 5 and a drive rod 6 connected to the drive end of the drive motor 5. A first bevel gear set 7 and a second bevel gear set 11 are provided on the outside of the drive rod 6.

[0037] The first bevel gear set 7 has a first driving gear 8 at its front end, and the top of the first driving gear 8 is meshed with a first driven gear 9. The front ends of the first driving gear 8 and the first driven gear 9 are respectively connected to a set of extrusion rollers 10.

[0038] The first driven gear 9 is rotatably connected to the inside of the device housing 2 through a bearing seat, and the front end of the second bevel gear set 11 is connected to the second driving gear 12, and the top of the second driving gear 12 is meshed with the second driven gear 13. The front end of the second driving gear 12 is fixedly connected to the stretching roller 14, and the front end of the second driven gear 13 is fixedly connected to the combing roller 15.

[0039] The second driven gear 13 is rotatably connected to the inside of the device housing 2 through the bearing seat, and the top of the device frame 1 is provided with a fixed frame 16. The device frame 1 is rotatably connected to the stretching roller 14 and the combing roller 15 through the fixed frame 16. The right end of the fixed frame 16 is provided with a limiting hole 17, and the fiber fabric body 4 passes through the limiting hole 17 and is wrapped with the stretching roller 14.

[0040] Example 2: This example discloses another guiding method, which is different from Example 1. The difference between this example and Example 1 is that a limiting roller is installed on the top of the device frame 1, and the limiting roller is located between the extrusion roller 10 and the stretching roller 14, and the limiting roller can guide the fiber fabric body 4.

[0041] Working principle: When using the uniaxial pre-stretching structure, it is first connected to an external power source. Then, the fiber fabric body 4 wrapped around the outside of the fiber roller 3 is wrapped around the outside of the extrusion roller 10 and the stretching roller 14. This can be done manually or with mechanical assistance from other equipment. Then, the drive mechanism inside the device housing 2 is activated, which in turn drives the smoothing mechanism and the combing mechanism to run. This causes the stretching roller 14 and the combing roller 15 to rotate synchronously. The stretching roller 14 will straighten and transfer the fiber fabric body 4 to the outside of the extrusion roller 10. At the same time, the combing roller 15 will also come into contact with the surface of the fiber fabric body 4, thereby combing the surface of the fiber fabric body 4 to prevent entanglement. Meanwhile, the two sets of extrusion rollers 10 will also rotate in opposite directions, so that the fiber fabric body 4 passes between the extrusion rollers 10 and is extruded and smoothed.

[0042] When the drive mechanism is running, the drive motor 5 drives the drive rod 6 to rotate, which in turn drives the first bevel gear set 7 and the second bevel gear set 11 to rotate. This causes the first bevel gear set 7 to drive the first drive gear 8 to rotate, and the first drive gear 8 to drive the first driven gear 9 to rotate, causing the two sets of extrusion rollers 10 to rotate in opposite directions. At the same time, the drive rod 6 also drives the second drive gear 12 to rotate, which in turn drives the second driven gear 13 to rotate. This causes the second drive gear 12 to drive the stretching roller 14 to rotate, and the second driven gear 13 to drive the combing roller 15 to rotate. Simultaneously, the fiber fabric body 4 can be moved and limited through the limiting hole 17.

[0043] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.

No reference numerals in the claims should be construed as limiting the scope of the claims.
