[0030] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will be combined with the drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0031] like Figures 1 to 3As shown, in one embodiment of the present invention, a yarn guide device for a carbon fiber warp knitting machine is provided. The carbon fiber warp knitting machine includes a warp knitting machine guardrail 1, which is originally provided on the outside of the carbon fiber warp knitting machine to protect the carbon fiber warp knitting machine. A yarn guide device is added to the warp knitting machine guardrail 1. The yarn guide device matches the 0° axis of the warp knitting machine. The yarn guide device facilitates the introduction of the rear of the carbon fiber warp knitting machine, thereby enabling further operation.

[0032] like Figures 1 to 3 As shown, the yarn guiding device includes two sliding seats 2, and the two sliding seats 2 are respectively slidably connected to the warp knitting machine guardrail 1. The upper end of the sliding seat 2 is fixedly connected to a bearing seat 3, and a passive yarn guide roller 4 is rotatably connected between the two bearing seats 3, and the passive yarn guide roller 4 is matched with the 0° axis of the carbon fiber warp knitting machine. The carbon fiber coming from the rear direction of the carbon fiber warp knitting machine is bypassed by the passive yarn guide roller 4, causing the direction of the carbon fiber to change, and then introduced into the forward direction of the carbon fiber warp knitting machine to play a steering role. The surface of the passive yarn guide roller 4 is treated with pear skin, so that the surface of the passive yarn guide roller 4 is formed with a pear skin surface. When the carbon fiber passes through the passive yarn guide roller 4, it is not easy to absorb the wool yarn, and there is no need to clean the roller surface frequently.

[0033] like Figures 1 to 3 As shown, the sliding base 2 includes a first slide 201 and a second slide 202, with a bearing housing 3 fixedly connected to the upper end of the sliding base 2. The first slide 201 and the second slide 202 are respectively positioned at the upper and lower ends of the guardrail bar of the warp knitting machine guardrail 1. A locking assembly is installed between the first slide 201 and the second slide 202. The locking assembly is used to secure the first and second slides 201 and 202 to the guardrail bar, thereby locking the passive yarn guide roller 4. In other words, when the position of the passive yarn guide roller 4 changes, the locking assembly can be released to allow the first and second slides 201 and 202 to slide on the guardrail bar. After sliding to the desired position, the first and second slides 201 and 202 can be locked using the locking assembly.

[0034] like Figures 1 to 3 As shown, the locking assembly includes a first bolt 203, a first mounting hole 2011 is defined on the first slide 201, and a second mounting hole 2021 is defined on the second slide 202 to match the first mounting hole 2011. The first bolt 203 passes through the first mounting hole 2011 and the second mounting hole 2021, and the other end of the first bolt 203 is threadedly connected to a nut 204. The outer wall of the first bolt 203 is in contact with the outer wall of the guardrail, thereby largely preventing the two sliding seats 2 from shifting in position during the sliding process of the sliding seat 2. In other words, it can minimize the tilting of the passive yarn guide roller 4 caused by adjusting the position of the passive yarn guide roller 4.

[0035] The yarn guide device is in use, first, need to be installed on the warp knitting machine guardrail 1.During installation, generally be to insert the first bolt 203 in the first mounting hole 2011 first, then the first mounting hole 2011 with the first bolt 203 is inserted on the guardrail, then the second mounting hole 2021 is aligned with the first bolt 203 from the lower end of the guardrail, and the second slide plate 202 is inserted in the first bolt 203, then screw on the nut 204, and then the passive yarn guide roller 4 is installed between the two bearing blocks 3.After installation is completed, according to the needs of the carbon fiber warp knitting machine, the position where the passive yarn guide roller 4 is located is adjusted, namely, slide the first slide plate 201 to the appropriate position on the guardrail, after the position adjustment is completed, the nut 204 is tightened, to realize the locking of the sliding seat 2 position.Then the carbon fiber coming from the carbon fiber warp knitting machine rear direction will bypass the passive yarn guide roller 4, change the direction of carbon fiber by the passive yarn guide roller 4, and then introduce the carbon fiber warp knitting machine forward direction, reach the effect of turning to, and simultaneously ensure the uniformity of the tension force of the monofilament as much as possible.

[0036] The yarn guide device of the utility model has a simple structure and does not need to destroy the structure of the original equipment during installation, so the installation and disassembly are relatively convenient.

[0037] The utility model is to directly put the 0° axial carbon fiber of the warp knitting machine onto the creel and introduce it from the rear of the warp knitting machine to achieve further operation. The 0° axial carbon fiber on the warp knitting machine can shorten the stroke of the carbon fiber introduction device through the yarn guide device.

[0038] In another embodiment, Figures 4 to 8 As shown, a connecting plate 5 is fixedly connected between the two sliding seats 2, a connecting rod 6 is rotatably connected to one side of the connecting plate 5, and a cleaning frame 7 is fixedly connected to the end of the connecting rod 6 away from the connecting plate 5. By rotating the connecting rod 6, one side of the cleaning frame 7 can be brought into contact with the passive yarn guide roller 4, and by pressing, one side of the cleaning frame 7 can be rubbed against the surface of the passive yarn guide roller 4, thereby cleaning the surface of the passive yarn guide roller 4.

[0039] Specifically, the contact surface of the cleaning frame 7 and the passive yarn guide roller 4 is detachably mounted with a cleaning component 701 by Velcro, and the cleaning component 701 can specifically be a cleaning cloth. The upper end of the connecting plate 5 is also provided with a collecting groove 501, and the collecting groove 501 can realize the storage of solvent. When the passive yarn guide roller 4 needs to be cleaned, a detergent can be applied to the passive yarn guide roller 4, and then the cleaning component 701 is contacted with the outer surface of the passive yarn guide roller 4 by rotating the connecting rod 6, so as to realize the cleaning of the passive yarn guide roller 4. The detergent and impurities finally fall into the collecting groove 501, so as to avoid as much as possible that impurities directly fall on the ground during the cleaning process, which is difficult to clean.

[0040] like Figures 4 to 8As shown, a drive structure 8 matching the connecting plate 5 is installed on the warp knitting machine guardrail 1. The drive structure 8 can control the change of the position of the connecting plate 5, that is, the drive structure 8 can control the change of the position of the passive yarn guide roller 4. Specifically, the drive structure 8 includes a threaded rod 9. A through hole 101 matching the threaded rod 9 is opened on the warp knitting machine guardrail 1. One end of the through hole 101 passes through the through hole 101 and is fixedly connected to the middle part of the connecting plate 5. By pulling the threaded rod 9, the connecting plate 5 can be moved on the warp knitting machine guardrail 1. The connecting plate 5 moves with the sliding seat 2, the sliding seat 2 moves with the bearing seat 3, and the bearing seat 3 moves with the passive yarn guide roller 4.

[0041] like Figures 4 to 8 As shown, the warp knitting machine guardrail 1 is also fixedly connected to a convex ring 102 that matches the threaded rod 9. The convex ring 102 is rotatably connected to the driving part 10, and the driving part 10 is provided with a threaded hole 1001 that matches the threaded rod 9. The threaded rod 9 and the driving part 10 are threadedly connected. During the rotation of the driving part 10, the threaded rod 9 can slide back and forth along the direction set by the through hole 101.

[0042] like Figures 4 to 8 As shown, a rubber pad 12 is fixedly connected between the driving part 10 and the warp knitting machine guardrail 1. The rubber pad 12 can increase the friction between the driving part 10 and the warp knitting machine guardrail 1. By increasing the friction, the resistance to the rotation of the driving part 10 is increased. When the staff does not manually rotate the driving part 10, the rotation of the driving part 10 by itself is reduced.

[0043] like Figure 5 As shown, a spring 11 is sleeved on the threaded rod 9 and is located between the connecting plate 5 and the warp knitting machine guardrail 1. The spring 11 is used to increase the friction between the driving part 10 and the threaded rod 9 to avoid the driving part 10 from rotating by itself as much as possible.

[0044] When in use, first you need to adjust the sliding seat 2 to a state where it can slide on the guardrail rod. When you need to adjust the position of the passive yarn guide roller 4, directly rotate the drive part 10, and the threaded hole 1001 is threadedly connected to the threaded rod 9. During the rotation process, the threaded rod 9 can be moved toward one end close to the passive yarn guide roller 4 or toward the end away from the passive yarn guide roller 4 to control the position of the passive yarn guide roller 4.

[0045] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0046] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
