Description

Technical Field

[0001] This utility model relates to a fiber tape production equipment for real-time carbon fiber widening, and particularly to the field of textile machinery technology. Background Technology

[0002] Carbon fiber broadening, also known as "carbonization," refers to the process of further heat-treating already manufactured carbon fibers at high temperatures to alter their crystallization pattern, thereby improving their mechanical properties and increasing their service life. Carbon fiber broadening is a key step in the carbon fiber manufacturing process.

[0003] In existing technologies, fiber tape production equipment cannot stretch carbon fibers in real time, resulting in relatively low efficiency. Utility Model Content

[0004] This invention provides a fiber tape production device for real-time carbon fiber widening to overcome the defects in the prior art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses a fiber tape production equipment for real-time carbon fiber spreading, including an outer frame and a movable spreading yarn frame installed inside it. The upper part of the movable spreading yarn frame is in contact with a linear unit servo motor on the guide rail B. It includes a frame, a constant tension unwinding yarn frame in the middle of the frame, a spreading machine at its tail, a yarn collecting machine at its end, and a yarn separating machine below the yarn collecting machine.

[0007] Furthermore, the outer frame includes a frame, the bottom of which is provided with a base plate, and the upper part of which is provided with a guide rail B. A linear unit servo motor is provided on the guide rail B, and the base plate is provided with a guide rail A.

[0008] Furthermore, the bottom of the movable yarn spreading frame is equipped with rollers, which cooperate with the guide rail A of the outer frame.

[0009] Furthermore, the linear unit servo motor serves as the power element for driving the movable yarn spreading frame, driving it to move back and forth.

[0010] The beneficial effects achieved by this utility model are as follows: The movable yarn spreading frame is installed inside the outer frame, and rollers are provided at its bottom. The rollers cooperate with the guide rail A of the outer frame. The linear unit servo motor drives the movable yarn spreading frame to move back and forth. When the warp knitting machine needs to pick up yarn, the movable yarn spreading frame slowly moves forward and prepares the spread yarn sheet at the same time. When it moves to the front end, the warp knitting machine completes the yarn picking. The movable yarn spreading frame moves backward, and the yarn sheet is still being prepared. The good yarn sheet prepared during the backward movement can be used as a reserve yarn sheet. When the warp knitting machine picks up yarn again, the reserve yarn sheet is supplied to the warp knitting machine through the movable yarn spreading frame moving forward. By repeating this process continuously, the real-time preparation of carbon fiber spread fiber tape can be achieved. Attached Figure Description

[0016] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0017] Example 1

[0018] like Figure 1-3 As shown, a fiber tape production device for real-time carbon fiber spreading includes an outer frame 1 and a movable spreading frame 2 installed inside it.

[0019] The outer frame 1 includes a frame 11, a base plate 12 at the bottom of the frame 11, a guide rail B14 on the upper part of the frame 11, a linear unit servo motor 15 on the guide rail B14, and a guide rail A13 on the base plate 12.

[0020] The upper part of the mobile yarn spreading frame 2 is in contact with the linear unit servo motor 15 on the guide rail B14. It includes a frame 25, a constant tension unwinding frame 21 in the middle of the frame 25, a yarn spreading machine 24 at its tail, a yarn collecting machine 22 at its end, and a yarn separating machine 23 below the yarn collecting machine 22.

[0021] This device is directly connected to the carbon fiber warp knitting machine. The mobile yarn spreading frame 2 is mainly used to prepare the carbon fiber spread yarn sheet in real time for the warp knitting machine. The mobile yarn spreading frame 2 is installed inside the outer frame 1, and its bottom is equipped with rollers. The rollers cooperate with the guide rail A13 of the outer frame 1. At the same time, the linear unit servo motor 15 drives the mobile yarn spreading frame 2 to move back and forth. When the warp knitting machine needs to pick up yarn, the mobile yarn spreading frame 2 slowly moves forward and prepares the spread yarn sheet at the same time. When it moves to the front end, the warp knitting machine completes the yarn picking. At this time, the mobile yarn spreading frame 2 begins to move backward, and the yarn sheet is still being prepared. The prepared yarn sheet after moving backward a certain distance can be used as a reserve yarn sheet. When the warp knitting machine picks up yarn again, the reserve yarn sheet can be supplied to the warp knitting machine through the mobile yarn spreading frame 2 moving forward. By repeating this process, the real-time preparation of carbon fiber spread fiber tape can be achieved.
