Description

Technical Field

[0001] This utility model mainly relates to the technical field of fiber bundle cutting, specifically a fiber bundle cutting device. Background Technology

[0002] In many industrial sectors today, fiber bundles play a crucial role. In the high-end textile industry, special fiber bundles used to make aerospace protective clothing need to be precisely cut to meet the stringent fabric weaving requirements. In the field of lightweight automotive parts manufacturing, carbon fiber bundles are precisely cut and then compounded with resin to reduce the weight and improve the quality of automobiles. In the building materials industry, the proper cutting of glass fiber bundles is the key to the preparation of high-strength glass fiber reinforced cement products.

[0003] Currently, in the fiber bundle processing flow, the fiber bundles are generally dried in a drying oven first to remove moisture and ensure stable bundle performance. Then, they undergo a fine flattening and straightening process to make the fiber bundles neatly arranged and with uniform tension. Finally, the fiber bundles are cleverly wound around a blade using tension for cutting. In this process, to ensure the accuracy and stability of the cutting, the blade needs to form an extremely stable connection with the device to prevent the blade from loosening or shifting at all during high-speed, high-force cutting. Otherwise, it is very easy to cause serious quality problems such as cutting size deviation and bundle breakage.

[0004] In existing disc-based cutting devices, most blades are fixed from the start of installation and cannot be adjusted. In actual production scenarios, different projects and customers have vastly different requirements for the cutting length of fiber bundles. For example, textile companies use drastically different fiber bundle lengths when producing lightweight spring / summer fabrics and heavy autumn / winter fabrics. Currently, they can only use disc structures of different sizes to replace the original ones to meet the cutting requirements of different fiber bundles, which is costly. Utility Model Content

[0005] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing solutions are too simplistic. Specifically, this utility model provides a fiber bundle cutting device to solve the technical problem mentioned in the background that most of the blades in existing disc-based cutting devices are fixed from the beginning of installation, lack the ability to adjust the blades, cannot adapt to different customers' requirements for the cutting length of fiber bundles, and can only be replaced by disc structures of different sizes.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0007] A fiber bundle cutting device includes a cutting mechanism, which includes a mounting plate, a first connecting plate, and a second connecting plate. The first connecting plate is located below the mounting plate and is connected to the mounting plate by bolts. The second connecting plate is located above the mounting plate. The mounting plate has multiple mounting openings arranged at equal intervals around it, and each mounting opening is provided with a detachable blade structure. The first connecting plate covers the lower end of the blade structure.

[0008] Furthermore, the second connecting plate is provided with a plurality of hexagonal through holes at equal intervals. Taking the center of the second connecting plate as a reference, every three hexagonal through holes located on the same radius line are set as a group, and each group of hexagonal through holes corresponds one-to-one with the mounting port on the first connecting plate.

[0009] Furthermore, each of the blade structures includes a shank, a blade, and a threaded portion, the threaded portion passing through a corresponding hexagonal through hole.

[0010] Furthermore, a nut is provided inside the hexagonal through hole, and the nut is threadedly connected to the corresponding threaded part, so that the second connecting plate can be installed on each blade structure.

[0011] Furthermore, the second connecting plate is provided with an annular baffle, and the annular baffle and the second connecting plate are connected by bolts.

[0012] Furthermore, the mounting plate has a connection hole at its center that can be connected to the motor drive unit.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention, through its mounting plate, first connecting plate, second connecting plate, hexagonal through hole, annular baffle, and blade structure, enables the annular cutting of fiber bundles during processing, achieving rapid severance. The fit between the nut, threaded part, and rod, along with the use of a screwdriver to twist the rod's end, allows for further adjustment of the blade spacing to accommodate different production needs. This eliminates the need for replacement with different sized structures, reducing costs and ensuring the stability of the adjusted blades. It allows for precise control of the blade's movement trajectory, ensuring the adjusted blades maintain ideal parallelism and concentricity. This results in consistently neat and smooth cuts when cutting fiber bundles, avoiding uneven cuts, broken fiber bundles, and other quality defects. This lays a solid foundation for subsequent processing steps, improving overall product quality. Furthermore, if a blade is damaged, it can be replaced individually without replacing the entire system, further reducing costs and optimizing economic efficiency.

[0015] The present invention will be explained in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0021] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly associated with those skilled in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] Please refer to the appendix carefully. Figure 1-4A fiber bundle cutting device includes a cutting mechanism 1, which includes a mounting plate 11, a first connecting plate 12, and a second connecting plate 13. The first connecting plate 12 is located below the mounting plate 11 and is connected to the mounting plate 11 by bolts. The second connecting plate 13 is located above the mounting plate 11. The mounting plate 11 has a plurality of mounting openings 111 arranged at equal intervals around it. Each mounting opening 111 is provided with a detachable blade structure 2. The first connecting plate 12 covers the lower end of the blade structure 2.

[0025] The aforementioned structure allows for continued adjustment of the distance between the blades to adapt to different production needs without requiring replacement with different sized structures, thus reducing costs. It also ensures the stability of the adjusted blades, enabling precise control of their movement trajectory and guaranteeing that the adjusted blades maintain ideal parallelism and concentricity. This results in consistently neat and smooth cuts when cutting fiber bundles, preventing uneven cuts, fiber breakage, and other quality defects. This lays a solid foundation for subsequent processing steps, improving the overall quality of the product. Furthermore, if a single blade is damaged, it can be replaced individually without replacing the entire equipment, further reducing costs and optimizing economic efficiency.

[0026] The specific operation is as follows: When it is necessary to change the distance between the blade structures 2, first unscrew the bolts between the first connecting plate 12 and the mounting plate 11. Then, the operator uses a screwdriver to tighten the head end of each rod 21 so that the threaded part 23 of the blade structure 2 is separated from the nut 3. Then the second connecting plate 13 can be removed from the blade structure 2. Since each set of hexagonal through holes 131 is set along the same radius straight line with the center of the second connecting plate 13 as the reference, the closer the hexagonal through hole 131 is to the center, the smaller the distance between the blade parts 22 and the shorter the cut fiber bundle. Conversely, the closer the distance is to the center, the longer the cut fiber bundle. Then, according to the requirements, a suitable hexagonal through hole 131 can be selected and the previously disassembled parts can be reassembled.

[0027] Please refer to the appendix carefully. Figure 2 and attached Figure 3 The second connecting plate 13 is provided with an annular baffle 14, which is connected to the second connecting plate 13 by bolts. The annular baffle 14 covers the outside of the hexagonal through hole 131, preventing wire ends or dust impurities from entering during the cutting process and affecting the subsequent blade adjustment. The mounting plate 11 is provided with a connecting hole 112 at its center, which can be connected to the motor drive unit. The connecting hole 112 allows it to be installed with the coupling at the motor output end, thereby achieving the purpose of driving the cutting mechanism 1 to rotate and cut.

[0028] Please refer to the appendix carefully. Figure 2 and attached Figure 4 The second connecting plate 13 has a plurality of hexagonal through holes 131 evenly spaced around it. Taking the center of the second connecting plate 13 as a reference, every three hexagonal through holes 131 located on the same radius line are grouped together, and each group of hexagonal through holes 131 corresponds one-to-one with the mounting port 111 on the first connecting plate 12. Through the layout design of each group of hexagonal through holes 131, the installation of the blade structure 2 is limited, thereby achieving the purpose of adjusting the distance between the blades. Each blade structure 2 includes a rod 21 and a blade 2. 2 and threaded portion 23, the threaded portion 23 passing through the corresponding hexagonal through hole 131, the rod portion 21 passing through the mounting port 111 on the mounting plate 11, a nut 3 is provided in the hexagonal through hole 131, and the nut 3 is threadedly connected to the corresponding threaded portion 23, so that the second connecting plate 13 can be installed on each blade structure 2. Through the cooperation between the threaded portion 23 and the hexagonal through hole 131, the blade structure 2, the first connecting plate 12, the mounting plate 11 and the second connecting plate 13 are connected together to form a stable cutting whole.

[0029] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
