[0030] The present invention will be further described below with reference to the accompanying drawings:

[0031] like Figures 1-4 As shown, a feeding device for a monofilament stretching machine includes a housing 1. A slide rail 5 and an adjusting motor 13 are provided on the housing 1. A sliding seat 6 is provided on the slide rail 5. A lead screw 12 is provided at the output end of the adjusting motor 13. The lead screw 12 and the sliding seat 6 are connected to each other. An unwinding box 7 is provided on the sliding seat 6. An unwinding shaft 8 is provided on the unwinding box 7. A tensioning component 11 is provided on the unwinding shaft 8. An upper crossbar 16 and a lower crossbar 19 are also provided on the housing 1. The upper crossbar 16 is located between the lower crossbar 19 and the unwinding shaft 8. An adjusting sensor 21 is fixedly provided on the upper crossbar 16. The adjusting sensor 21 is electrically connected to the adjusting motor 13.

[0032] Specifically, a mounting bracket 2 is fixedly installed on the chassis 1, and a set of support plates 4 are fixedly installed on the mounting bracket 2. The slide rail 5 is fixedly installed on the mounting bracket 2 between the two support plates 4. The lead screw 12 is located between the two support plates 4, and its two ends are rotatably connected to the support plates 4 respectively. The adjusting motor 13 is fixedly installed on one of the support plates 4, and its output end is connected to one end of the lead screw 12. This arrangement provides stable support for the slide rail 5 and the sliding seat 6 through the mounting bracket 2, and the two support plates 4 ensure the cooperation between the lead screw 12 and the sliding seat 6.

[0033] Specifically, a positioning ring 10, a tensioning component 11, and a handle 9 are fixedly installed on the unwinding shaft 8. The positioning ring 10 is fixedly fitted on the unwinding shaft 8, the tensioning component 11 is located on the unwinding shaft 8 on one side of the positioning ring 10, and the handle 9 is located on the unwinding shaft 8 on the other side of the positioning ring 10. The handle 9 is connected to the tensioning component 11. This arrangement can fix the material roll 23.

[0034] like Figure 4As shown, the tensioning assembly 11 includes a fixed ring 111 fixedly connected to the unwinding shaft 8 and a sliding ring 112 slidably fitted on the unwinding shaft. A rubber sleeve 113 is provided between the fixed ring 111 and the sliding ring 112. Under the push of the elastic element, the sliding ring 112 squeezes the rubber sleeve 113 against the fixed ring 111. During the squeezing process, the rubber sleeve 113 expands outward along the radial direction of the unwinding shaft 8, thereby fixing the material roll 23. Rotating the handle 9 can move the sliding ring 112 away from the fixed ring 111, causing the rubber sleeve 113 to lose compression and shrink inward, facilitating the installation of the material roll 23.

[0035] Specifically, the unwinding box 7 is also equipped with a guide rod 14. The guide rod 14 is detachably mounted on the unwinding box 7 via a fixing buckle 15. The fixing buckle 15 is connected to the unwinding box 7 by bolts. This arrangement can both fix the guide rod 14 and adjust the extension length of the guide rod 14 to match different lengths of material rolls 23.

[0036] Specifically, the chassis 1 is also equipped with a rear tensioning rod 17 and a front tensioning rod 18. The front tensioning rod 18 is located below the upper crossbar 16, and the rear tensioning rod 17 is located below the lower crossbar 19. This arrangement can tension the carbon fiber bundle 22 and prevent the carbon fiber bundle 22 from coming out between the two sensors.

[0037] Specifically, a limit ring 20 is fixedly installed on the lower crossbar 19, and there are two limit rings 20 on the lower crossbar 19 and two adjustment sensors 21 on the upper crossbar 16. With this arrangement, the adjustment motor 13 can be precisely controlled by the cooperation of the two sensors, and the two limit rings 20 can limit the position of the carbon fiber bundle 22 output by the feeding device.

[0038] Specifically, a fixing plate 3 is provided on the chassis 1, and the upper crossbar 16 is fixedly installed on the fixing plate 3. This arrangement allows the position and number of the upper crossbar 16 to be adjusted through the fixing plate 3.

[0039] The working process of this embodiment is as follows: Before using this device, the material tube needs to be installed on the feeding shaft. During installation, the diameter of the tensioning mechanism can be reduced by turning the handle 9. Then, the material roll 23 is put on the feeding shaft so that one end of the material tube is in contact with the positioning ring 10. Then, the handle 9 is released, and the diameter of the tensioning mechanism will increase. The friction between the tensioning mechanism and the material roll 23 is used to fix the material tube on the feeding shaft so that the material roll 23 can rotate with the feeding shaft.

[0040] Then the carbon fiber bundles 22 on the coil 23 are arranged according to Figure 3The carbon fiber bundle 22 passes through the guide rod 14, upper crossbar 16, front tension rod 18, rear tension rod 17, and lower crossbar 19. When winding the carbon fiber bundle 22, it is necessary to ensure that the carbon fiber bundle 22 passes between the two adjustment sensors 21 on the upper crossbar 16 and between the two limit rings 20 on the lower crossbar 19. During processing, the subsequent equipment will pull the carbon fiber bundle 22, and the material roll 23 will start to rotate for unwinding. If the carbon fiber bundle 22 deviates from one of the sensors during the unwinding process, it will be detected by the sensor. At this time, the sensor will send a signal to the adjustment motor 13, causing the adjustment motor 13 to drive the lead screw 12 to rotate. The lead screw 12 drives the sliding seat 6 to move along the slide rail 5 in the opposite direction of the deviation of the carbon fiber bundle 22. After the sliding seat 6 moves, it will drive the material roll 23 to move, so that the carbon fiber bundle 22 can return to the space between the two adjustment sensors 21.

[0041] By setting a front tension rod 18 and a rear tension rod 17 on the housing 1, the problem of the carbon fiber bundle 22 coming off between the two adjustment sensors 21 due to the material roll 23 being unwound too quickly during the unwinding process can be avoided.

[0042] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
