Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology, and in particular to a filament guide. Background Technology

[0002] During the filament winding process, a guide is needed to guide the filament. However, because the filament itself is quite thin and its color is sometimes similar to that of the machine, and because a worker often needs to monitor multiple machines at the same time, it is often difficult to detect in time when the filament breaks. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a filament guide that features automatic alerts when a filament breaks.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A filament guide, comprising:

[0006] Connector;

[0007] Two connecting rods are symmetrically fixed to the connector;

[0008] Two marking structures are provided, each including a disk and a marking rod. The disk is eccentrically rotatably connected to a connecting rod. The marking rod extends radially along the disk and is positioned near the rotatable connection between the disk and the connecting rod.

[0009] A guide wheel is rotatably mounted on the disk and is coaxially arranged with the disk.

[0010] In the aforementioned filament guide, the connector includes a body, a jaw, and an adjusting screw. The body has a limiting groove, and the jaw has a sliding part, an adjusting part, and a limiting part. The sliding part is slidably connected to the body, and the limiting part is located at the groove opening aligned with the limiting groove. The adjusting part is located on the side of the body opposite to the limiting groove. The adjusting screw is threadedly connected to the adjusting part and abuts against the body. The adjusting screw is used to adjust the distance between the limiting part and the limiting groove.

[0011] In the above-mentioned filament guide, the main body has a first limiting wall and a second limiting wall, the first limiting wall and the second limiting wall are the boundaries of the limiting groove, the first limiting wall is longer than the second limiting wall, and the sliding part is slidably disposed on the first limiting wall.

[0012] In the above-mentioned filament guide, a sliding channel is provided on the first limiting wall, and the sliding part passes through the sliding channel.

[0013] In the aforementioned filament guide, the marking rod is red or green.

[0014] In the above-mentioned filament guide, the guide wheel is connected to the disc by a hand-tightening screw, which passes through the hole in the middle of the guide wheel.

[0015] In the aforementioned filament guide, the guide wheel is made of ceramic material.

[0016] In the above-mentioned filament guide, when the guide wheel is not subjected to external force, the marking rod is parallel to the direction of gravity.

[0017] Compared with the prior art, this application has the following advantages:

[0018] The marking structure solves the problem of the filament color being similar to the machine color, making it difficult to distinguish the filament condition. The position of the marking rod forms a clear visual identifier. Even if the filament is thin and the color is not conspicuous, the staff can quickly judge that the filament may be broken or other abnormalities by the abnormal changes of the marking rod. In scenarios where one staff member needs to manage multiple devices at the same time, the marking rod can attract attention from a distance, reduce the difficulty of manual inspection, and improve the efficiency of fault detection.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0030] like Figures 1 to 3 As shown, a filament 200 guide includes: a connector 2, two connecting rods 3, two marking structures 4, and a guide wheel 5. The two connecting rods 3 are symmetrically fixed to the connector 2. The marking structure 4 includes a disk 41 and a marking rod 42. The disk 41 is eccentrically rotatably connected to the connecting rod 3. The marking rod 42 extends along the radial direction of the disk 41 and is located near the rotatable connection position between the disk 41 and the connecting rod 3. The guide wheel 5 is rotatably mounted on the disk 41 and is coaxially arranged with the disk 41.

[0031] When the filament 200 is wound, it passes around the guide wheel 5. As the winding process progresses, the guide wheel 5 drives the disc 41 to rotate eccentrically on the connecting rod 3. The tension of the filament 200 causes the guide wheel 5 to be subjected to external force, causing the disc 41 to rotate eccentrically. The marker rod 42 deviates from its initial position. At this time, the operator can visually judge whether the filament 200 is in a normal guiding and winding state by observing the position of the marker rod 42. When there is no external force on the guide wheel 5, the marker rod 42 returns to its normal position due to gravity, forming a visual warning.

[0032] The presence of the marking structure 4 solves the problem that the color of the filament 200 is similar to that of the machine, making it difficult to distinguish the state of the filament. The position of the marking rod 42 forms a clear visual identifier. Even if the filament 200 is thin and the color is not conspicuous, the staff can quickly judge the abnormal situation such as the breakage of the filament 200 by the abnormal changes of the marking rod 42. In the scenario where one staff member needs to manage multiple devices at the same time, the marking rod 42 can attract attention from a distance, reduce the difficulty of manual inspection, and improve the efficiency of fault detection.

[0033] Specifically, the connector 2 includes a body 21, a claw 22, and an adjusting screw 23. The body 21 has a limiting groove 211. The claw 22 has a sliding part 221, an adjusting part 222, and a limiting part 223. The sliding part 221 is slidably connected to the body 21. The limiting part 223 is located at the slot opening of the limiting groove 211. The adjusting part 222 is located on the side of the body 21 away from the limiting groove 211. The adjusting screw 23 is threadedly connected to the adjusting part 222 and abuts against the body 21. The adjusting screw 23 is used to adjust the distance between the limiting part 223 and the limiting groove 211.

[0034] By rotating the adjusting screw 23, the adjusting screw 23 applies force to the adjusting part 222 using the principle of thread transmission. Since the adjusting part 222 is connected to the sliding part 221, under the pushing or pulling action of the adjusting screw 23, the sliding part 221 drives the pawl 22 to slide on the main body 21. When the adjusting screw 23 is screwed in, the limiting part 223 of the pawl 22 moves closer to the limiting groove 211, reducing the distance between the limiting part 223 and the limiting groove 211. When the adjusting screw 23 is screwed out, the limiting part 223 moves away from the limiting groove 211, increasing the distance between the two. In this way, the connector 2 can be conveniently installed directly on the rod body 100 of the machine equipment.

[0035] Specifically, the main body 21 has a first limiting wall 212 and a second limiting wall 213. The first limiting wall 212 and the second limiting wall 213 are the boundaries of the limiting groove 211. The first limiting wall 212 is longer than the second limiting wall 213. The sliding part 221 is slidably disposed on the first limiting wall 212.

[0036] This design allows the rod 100 of the machine to easily enter the limiting groove 211. The rod 100 can be fed into the limiting groove 211 from the direction of the second limiting part 223. Then the position of the limiting part 223 can be adjusted so that it is fastened to the rod 100 by the limiting part 223.

[0037] Specifically, a sliding channel is provided on the first limiting wall 212, and the sliding part 221 passes through the sliding channel.

[0038] The sliding channel provides a clear linear motion trajectory for the sliding part 221 of the chuck 22, so that the sliding part 221 can only move along the channel direction.

[0039] Specifically, the marker rod 42 is red or green.

[0040] This makes it easy for staff to see the position of marker 42, allowing them to quickly identify the problem area from among many devices. Of course, in practical applications, other colors can be chosen as the standard, as long as it is easy for staff to see.

[0041] Specifically, the guide wheel 5 is connected to the disc 41 by a hand-tightening screw 6, which passes through the hole in the middle of the guide wheel 5.

[0042] The guide wheel 5 can be installed or removed by hand-tightening the screw 6 without tools, making it easy to replace. The tightening direction of the screw 6 is the same as the rotation direction of the guide wheel 5.

[0043] Specifically, the guide wheel 5 is made of ceramic material.

[0044] Specifically, when the guide wheel 5 is not subjected to external force, the marker rod 42 is parallel to the direction of gravity.

[0045] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture, as shown in the attached figure. If the specific posture changes, the directional indication will also change accordingly.

[0046] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Meanwhile, the word "and / or" throughout the text means including three solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.
