Abstract
Description
Technical Field
[0001] This utility model relates to the field of yarn production technology, and in particular to a yarn anti-tangle guide for a warping machine. Background Technology
[0002] Warping machines are crucial mechanical devices in the textile industry, playing a key role in the textile production process. They are preparatory equipment for warp knitting, winding yarn evenly onto warp beams with a certain tension according to the required number and length of yarn for the knitting machine. During operation, warping machines are equipped with yarn guides to prevent yarn tangling during transport. However, the yarn guides have fixed positions at both ends for yarn entry and exit, resulting in a fixed angle for the yarn to pass through them. When the angle is large, the friction between the yarn and the protective sleeve inside the guide increases, hindering yarn transport. Utility Model Content
[0003] The main purpose of this utility model is to provide a yarn anti-tangle guide for a warping machine, which can effectively solve the problems in the background art.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A yarn anti-tangle guide for a warping machine includes a mounting base and a threaded rod. The threaded rod is fixedly mounted on the upper surface of the mounting base at its center. A guide block is sleeved on the surface of the threaded rod near its lower end. A tray is sleeved on the surface of the threaded rod below and above the guide block. A limiting cap is threaded on the surface of the threaded rod at its upper end. A No. 1 spring is sleeved on the surface of the threaded rod below the limiting cap. Guide frames are embedded on the upper surfaces of both ends of the mounting base. A protective sleeve is embedded inside the upper end of the guide frame.
[0006] More preferably, the upper surfaces of both ends of the mounting base are provided with rod grooves, and the upper surface of the mounting base and the periphery of the rod grooves are provided with adjustment grooves. The number of adjustment grooves is several, and the several adjustment grooves are distributed in a circular shape around the rod grooves on the upper surface of the mounting base.
[0007] More preferably, the upper end of the conductor frame has an installation hole, the lower surface of the conductor frame and the middle part of it are fixedly installed with a guide rod embedded in the rod groove, the lower surface of the guide rod is fixedly installed with a stop block, the lower surface of the conductor frame and the sides are fixedly installed with a positioning rod embedded in the adjustment groove, and a second spring is sleeved on the surface of the guide rod inside the rod groove.
[0008] More preferably, the protective sleeve is embedded in the mounting hole.
[0009] Compared with the prior art, this utility model proposes a yarn anti-tangle guide for a warping machine, which has the following beneficial effects:
[0010] In this invention, by setting up a guide wire frame and a mounting base that cooperate with each other, by pulling up the guide wire frame, the lower end of the guide wire frame's positioning rod is disengaged from the adjustment groove of the mounting base. The guide wire frame can then be rotated so that the protective sleeve at the upper end of the guide wire frame faces different positions. Then, the external force pulling up the guide wire frame can be released. At this time, the guide wire frame descends under the action of the second spring until the positioning rod of the guide wire frame is embedded in another adjustment groove. This allows the orientation of the guide wire frame to be adjusted, avoiding increased friction between the yarn and the protective sleeve inside the guide wire frame due to a large angle at which the yarn passes through the guide wire frame.

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0016] It should be noted that all directional indicators such as up, down, left, right, front, back, etc. in the embodiments of this utility model 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 indicator will also change accordingly.
[0017] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can refer to a fixed connection, a detachable connection, or an integral part; it can also refer to a mechanical connection, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0018] like Figure 1-3 As shown, a yarn anti-tangle guide for a warping machine includes a mounting base 1 and a threaded rod 2. The threaded rod 2 is fixedly mounted on the upper surface of the mounting base 1 at the middle. A guide block 6 is sleeved on the surface of the threaded rod 2 near its lower end. A tray 5 is sleeved on the surface of the threaded rod 2 below and above the guide block 6. A limiting cap 3 is threaded on the surface of the threaded rod 2 at its upper end. A No. 1 spring 4 is sleeved on the surface of the threaded rod 2 below the limiting cap 3. Guide frames 7 are embedded on the upper surfaces of both ends of the mounting base 1. A protective sleeve 8 is embedded inside the upper end of the guide frame 7.
[0019] In a preferred embodiment: rod grooves 101 are provided on the upper surfaces of both ends of the mounting base 1, and adjustment grooves 102 are provided on the upper surface of the mounting base 1 and around the rod grooves 101. There are several adjustment grooves 102, and the several adjustment grooves 102 are distributed in a circular shape around the rod grooves 101 on the upper surface of the mounting base 1.
[0020] In the above structure, since there are several adjustment slots 102, the positioning rod 704 of the wire frame 7 can be inserted into the adjustment slots 102 at different positions, so that the wire frame 7 can be positioned after rotating at different angles.
[0021] In a preferred embodiment: the upper end of the conductor frame 7 has an installation hole 705, the lower surface of the conductor frame 7 and the middle part of it are fixedly installed with a guide rod 701 embedded in the rod groove 101, the lower surface of the guide rod 701 is fixedly installed with a stop block 702, the lower surface of the conductor frame 7 and the sides are fixedly installed with a positioning rod 704 embedded in the adjustment groove 102, and the surface of the guide rod 701 located inside the rod groove 101 is fitted with a second spring 703.
[0022] In the above structure, the second spring 703 must ensure that the positioning rod 704 of the conductor frame 7 is embedded in the adjustment groove 102 of the mounting base 1 in its natural state. This is so that the conductor frame 7 can maintain its angle after the angle is adjusted. The stop block 702 can prevent the lower end of the guide rod 701 from completely disengaging from the rod groove 101 when the conductor frame 7 is pulled up.
[0023] In a preferred embodiment, the protective sleeve 8 is fitted into the mounting hole 705.
[0024] In use, the mounting base 1 is fixed in the mounting position using a fastener. Then, the yarn passes through the protective sleeves 8 of the two wire frames 7 and the wire block 6 between the two trays 5. By pulling the wire frame 7 upward, the lower end of the positioning rod 704 of the wire frame 7 is disengaged from the adjustment groove 102 of the mounting base 1. The wire frame 7 can then be rotated so that the protective sleeve 8 at the upper end of the wire frame 7 faces different positions. Then, the external force pulling the wire frame 7 can be released. At this time, the wire frame 7 descends under the action of the second spring 703 until the positioning rod 704 of the wire frame 7 is embedded in another adjustment groove 102. In this way, the orientation of the wire frame 7 can be adjusted to avoid increasing the friction between the yarn and the protective sleeve 8 inside the wire frame 7 due to the large angle at which the yarn passes through the wire frame 7.
[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
