Description

Technical Field

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

[0002] Carbon fiber precursor, also known as carbon fiber preform, refers to the polymer filament used in the production of carbon fiber. During production, a cutting device is needed to cut the carbon fiber filament to obtain the required length.

[0003] Carbon fiber filament cutting devices often cut carbon fiber filaments with a cutter. During this process, the carbon fiber filaments are prone to deviating as the cutter moves downward, which affects the cutting of the carbon fiber filaments and the subsequent conveying of the carbon fiber filaments. Utility Model Content

[0004] This utility model mainly provides a carbon fiber filament processing and cutting device to solve the technical problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A carbon fiber filament processing and cutting device includes a cutting table, a wire breaking mechanism connected to the upper surface of the cutting table, and wire feeding mechanisms on both sides of the wire breaking mechanism.

[0007] The wire breaking mechanism includes a support frame connected to the upper surface of the cutting table, a support plate connected to the top of the support frame, and a cylinder connected to the upper surface of the support plate. The piston rod of the cylinder is connected to a cutter and a clamping assembly.

[0008] Furthermore, the cutting table includes a cutting groove at its top end, which is located at the bottom end of the cutter.

[0009] Furthermore, the clamping assembly includes a lifting plate slidably connected to the outside of the piston rod of the cylinder, with clamping rollers connected to both ends of the bottom of the lifting plate, and the lifting plate is located at the top of the cutter.

[0010] Furthermore, the top of the cutter is provided with a convex ring connected to the outside of the piston rod of the cylinder, and a spring is connected to the lower surface of the convex ring. The end of the spring away from the convex ring is connected to the upper surface of the lifting plate.

[0011] Furthermore, the pressing roller includes bearing seats connected to both ends of the lower surface of the lifting plate, and a roller body rotatably connected between the two bearing seats on the same side.

[0012] Furthermore, the wire feeding mechanism includes rotating shaft seats connected to both sides of the upper surface of the cutting table, and a wire feeding roller is connected between the two rotating shaft seats.

[0013] Furthermore, a motor is connected to one side of one of the rotating shaft seats, and the output shaft of the motor is connected to the adjacent feed roller.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In this invention, when the cylinder drives the cutter to move down into the cutting groove and the clamping roller presses down on the carbon fiber filament, the piston rod of the cylinder drives the convex ring, which in turn compresses the spring, thereby pressing the lifting plate by the spring. This ensures that the clamping roller connected to the lifting plate can tightly press down on the carbon fiber filament. In this way, excessive compression of the cutting table and carbon fiber filament before cutting is prevented.

[0016] The present invention will be explained in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0020] 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.

[0021] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of this invention is for the purpose of describing particular embodiments only 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.

[0023] For an example, please refer to the appendix. Figure 1-2 A carbon fiber filament processing and cutting device includes a cutting table 1, a wire breaking mechanism 2 connected to the upper surface of the cutting table 1, and wire feeding mechanisms 3 provided on both sides of the wire breaking mechanism 2.

[0024] The wire breaking mechanism 2 includes a support frame 21 connected to the upper surface of the cutting table 1, a support plate 22 connected to the top of the support frame 21, and a cylinder 23 connected to the upper surface of the support plate 22. The piston rod of the cylinder 23 is connected to a cutter 29 and a clamping assembly 24.

[0025] For details, please refer to the appendix. Figure 1 and 2 The cutting table 1 includes a cutting groove 11 at its top end, and the cutting groove 11 is located at the bottom end of the cutter 29;

[0026] The clamping assembly 24 includes a lifting plate 25 that is slidably connected to the outside of the piston rod of the cylinder 23. The bottom ends of the lifting plate 25 are connected to clamping rollers 26, and the lifting plate 25 is located at the top of the cutter 29.

[0027] It should be noted that, in this embodiment, the groove 11 provides space for the cutter 29 to move, so that the cutter 29 can extend into the groove and cut the carbon fiber filaments.

[0028] Furthermore, the cylinder 23 drives the cutter 29 to descend, and the pressure rollers 26 on both sides of the cutter 29 press the carbon fiber filaments, thereby preventing the carbon fiber filaments from deviating when cutting them.

[0029] For details, please refer to the appendix. Figure 1 and 2 The top of the cutter 29 is provided with a convex ring 28 connected to the outside of the piston rod of the cylinder 23. A spring 27 is connected to the lower surface of the convex ring 28. The end of the spring 27 away from the convex ring 28 is connected to the upper surface of the lifting plate 25.

[0030] The pressing roller 26 includes bearing seats 261 connected to both ends of the lower surface of the lifting plate 25, and roller body 262 rotatably connected between the two bearing seats 261 on the same side.

[0031] It should be noted that in this embodiment, when the cylinder 23 drives the cutter 29 to move down into the cutting groove 11 and the pressing roller 26 presses the carbon fiber filament, the piston rod of the cylinder 23 drives the convex ring 28, which in turn compresses the spring 27, thereby pressing the lifting plate 25 through the spring 27. This ensures that the pressing roller 26 connected to the lifting plate 25 can tightly press the carbon fiber filament. In this way, the cutting table 1 and the carbon fiber filament are not excessively compressed before the cutting process.

[0032] Furthermore, the roller body 262 is supported by the bearing housing 261.

[0033] For details, please refer to the appendix. Figure 1 and 2 The wire feeding mechanism 3 includes a rotating shaft seat 31 connected to both sides of the upper surface of the cutting table 1, and a wire feeding roller 32 is connected between the two rotating shaft seats 31.

[0034] One of the rotating shaft seats 31 is connected to a motor 33 on one side, and the output shaft of the motor 33 is connected to the adjacent feed roller 32;

[0035] It should be noted that in this embodiment, the conveying roller 32 is supported by the rotating shaft seat 31, and the conveying roller 32 is driven by the motor 33. The rotation of the conveying roller 32 drives the carbon fiber to move.

[0036] The specific operation method of this utility model is as follows:

[0037] When cutting carbon fiber filaments, the cylinder 23 drives the cutter 29 to descend, and the pressure rollers 26 on both sides of the cutter 29 press the carbon fiber filaments to prevent them from deviating when cutting.

[0038] When the cylinder 23 drives the cutter 29 to move down into the cutting groove 11 and the pressure roller 26 presses down on the carbon fiber filament, the piston rod of the cylinder 23 drives the convex ring 28, which in turn compresses the spring 27. This, in turn, presses down on the lifting plate 25, so that the pressure roller 26 connected to the lifting plate 25 can press down on the carbon fiber filament. In this way, the cutting table 1 and the carbon fiber filament are not overly compressed before the cutting process.

[0039] 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.
