Description

Technical Field

[0001] This utility model relates to the field of spinning, and in particular to an integrated spinning head. Background Technology

[0002] The spinning head is an accessory in spinning, which not only guides the yarn but also assists in controlling the yarn tension.

[0003] Most existing wire-spinning heads adopt a split structure, as shown in Figure 1, including a wire guide 1, a structural body 3, and a metal connecting rod 2. During use, bolts or other tools are needed to assemble the metal connecting rod 2 onto the structural body 3, and then adhesive is used to bond the wire guide 1 to the metal connecting rod 2. The above-mentioned split-structure wire-spinning head has the following problems in practical use:

[0004] 1. When the spinning head is used for a long time, the adhesive is prone to failure, which can cause the yarn guide to loosen or even fall off. During production, this can cause differences in the running angle, vibration and air ring condition of the yarn, resulting in abnormal spinning positions such as fuzz, yarn tripping, and yarn breakage, which will affect the production quality.

[0005] 2. The spinning head consists of three parts. As we all know, the more parts there are, the more unstable it will be. During use, one end of the metal connecting rod is prone to shaking, which will cause the wire guide to shake and further affect the production quality of the wire.

[0006] 3. With prolonged use, the guide wire will inevitably wear out, so it needs to be replaced. When replacing the guide wire, the adhesive needs to be removed, which is inconvenient. Utility Model Content

[0007] In order to overcome the above-mentioned defects of the prior art, the present invention provides an integrated spinning head to solve the problems existing in the background art.

[0008] This utility model provides the following technical solution: an integrated spinning head, comprising a spinning guide and a connecting body, characterized in that: a connecting arm is integrally provided at one end of the connecting body, and a slot adapted to the spinning guide is provided at the end of the connecting arm, and a locking device is hinged to the side of the slot.

[0009] The locking device rotates along the central axis of the hinge to lock and limit the wire guide.

[0010] Preferably, the locking device includes two clamps, which are assembled at one end via a connecting shaft and the other end of the two clamps are detachably assembled via a screw, with a nut provided at one end of the screw.

[0011] Preferably, the other ends of the two clamps are connected to a connecting rod, so that the two clamps rotate synchronously along the hinged central axis, and the connecting body is provided with a fan-shaped groove on the periphery of the groove to provide the motion trajectory of the connecting rod.

[0012] Preferably, the clamp has a fan-shaped structure, and the curvature of the clamp is adapted to the groove.

[0013] Preferably, the connecting arm has the same thickness as the guide wire.

[0014] Preferably, the guide wire is made of ceramic material.

[0015] Preferably, the connecting body and connecting arm are made of plastic material.

[0016] Preferably, the connecting body and the connecting arm are manufactured by integral injection molding.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This utility model places the wire guide in the slot, and rotates the locking device to contact the upper and lower surfaces of the wire guide, thereby firmly fixing the wire guide in the slot, replacing the adhesive connection method. When disassembling, simply rotate the locking device to expose the wire guide and pull it out, which improves the convenience of later maintenance and replacement. At the same time, the snap-locking method greatly improves the stability of the wire guide and avoids the wire guide from loosening, thereby ensuring the quality of wire production.

[0019] 2. This utility model integrates the connecting arm and the connecting body of the spinning head into one piece, replacing the existing detachable installation method of metal connecting rod and plastic product connecting body. This reduces the number of components, thereby improving the stability of the spinning head and reducing the shaking of the spinning head during use. Attached Figure Description

[0024] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0025] This utility model provides an integrated spinning head, as shown in Figures 2-3, including a spinning guide 1 and a connecting body 3. One end of the connecting body 3 is integrally provided with a connecting arm 2. At the end of the connecting arm 2, a slot adapted to the spinning guide 1 is provided. A locking device 4 is hinged to the side of the slot. The locking device 4 rotates along the central axis of the hinge to lock and limit the spinning guide 1.

[0026] Specifically, during installation, the wire guide is placed in the slot, and then the locking device 4 is rotated so that the inner wall of the locking device 4 contacts the upper and lower surfaces of the wire guide 1, thereby firmly fixing the wire guide 1 in the slot, replacing the adhesive connection method. When disassembling, simply rotate the locking device 4 to expose the wire guide 1 and pull it out, which improves the convenience of later maintenance and replacement. At the same time, the snap-locking method greatly improves the stability of the wire guide 1, avoiding the occurrence of loosening of the wire guide 1, thereby ensuring the quality of wire production.

[0027] The connecting arm 2 and the connecting body 3 of the spinning head are integrated into one piece, replacing the existing detachable installation method of metal connecting rod and plastic product connecting body 3. This reduces the number of components, thereby improving the stability of the spinning head and reducing the shaking of the spinning head during use.

[0028] In this embodiment, the locking device 4 includes two clamps 41, which are respectively arranged above and below the slot, with the front end of each clamp protruding from the slot to limit the wire guide in the slot. The two clamps 41 are mounted at one end via a connecting shaft 42, allowing them to rotate synchronously. The other ends of the clamps 41 are detachably mounted via a screw 43, with a nut at one end for securing the two clamps 41.

[0029] The two clamps 41 are fixedly connected, so that the other end of the two clamps 41 is connected and assembled with the connecting arm through the screw 43, thereby limiting the wire guide after the two clamps 41 are connected and assembled.

[0030] It can be explained here that the connecting arm 2 is provided with a hole for the connecting shaft 42 to pass through. The connecting shaft 42 is vertically rotated and assembled in the hole. When one of the clamps 41 is rotated, the other clamp 41 also rotates synchronously.

[0031] Furthermore, the other ends of the two clamps 41 are connected to a connecting rod 44, allowing the two clamps 41 to rotate synchronously along the hinged central axis. The connecting body 3, located on the periphery of the groove, has a fan-shaped groove 31 for providing the movement trajectory of the connecting rod 44. The other ends of the two clamps 41 are connected via the connecting rod 44, and the connecting shaft 42, in conjunction with the connecting rod 44, further improves the stability of the connection and assembly of the two clamps 41, enabling the two clamps 41 to move synchronously.

[0032] It can be noted that the connecting part 3 has a fan-shaped groove 31, which is used for the movement of the connecting rod.

[0033] 44 provides the necessary space for movement, and the other end of each of the two clamps 41 is provided with a hole for the screw 43 to pass through. The connecting arm 2 is also provided with a hole for the connecting rod 44 to pass through. The connecting rod 44 can be vertically inserted into the hole and connected to the two clamps 41 (at this time, the holes on the two clamps 41 are coaxial with the holes on the connecting arm 2). Finally, the nuts are used to fix it, so as to realize the assembly of the two clamps 41 and the connecting arm 2.

[0034] In this embodiment, the clamp 41 has a fan-shaped structure, and the curvature of the clamp 41 is adapted to the groove, so that the inner wall of the clamp 41 is in full contact with the upper and lower surfaces of the wire guide 1 inside the groove, thereby increasing the contact area between the clamp 41 and the upper and lower surfaces of the wire guide 1, and thus improving the limiting effect on the wire guide.

[0035] In this embodiment, the connecting arm 2 and the wire guide 1 have the same thickness, so that the upper and lower surfaces of the wire guide 1 are level with the upper and lower surfaces of the connecting arm 2, thereby improving the fixing effect of the clamp 41 on the wire guide 1 inside the slot.

[0036] In this embodiment, the wire guide 1 is made of ceramic material, which improves the lifespan of the wire guide 1.

[0037] In this embodiment, the connecting body 3 and the connecting arm 2 are made of plastic. Furthermore, the connecting body 3 and the connecting arm 2 are integrally injection molded, and the connecting arm 2 and the connecting body 3 of the thread-extracting head are integrally formed, replacing the existing method of detachable installation of the connecting body 3 made of metal connecting rod and plastic product.

[0038] This design reduces the number of components, thereby improving the stability of the spinning head and reducing the likelihood of it shaking during use.

[0039] The working principle of this utility model:

[0040] When assembling the wire guide 1, directly embed the wire guide 1 into the slot opened in the connecting arm 2, and keep the upper and lower surfaces of the wire guide 1 horizontal with the upper and lower surfaces of the connecting arm. Then rotate one end of the clamp 41 to the screw position, and finally insert the screw and nut to fix the two clamps 41 on the connecting arm 2 to fix and limit the wire guide 1. When disassembling, unscrew the nut, pull out the screw 43, and rotate the two clamps 41 in opposite directions until the clamps 41 are completely disengaged from the slot, and then the wire guide 1 can be pulled out for replacement.

[0041] Several points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
