Description

Technical Field

[0001] This utility model relates to the field of weft feeder technology, specifically a positioning device for weft feeders. Background Technology

[0002] In the field of textile machinery, the loom is the core equipment, and its efficient and stable operation is crucial to the production quality and efficiency of textiles. The weft feeder, as an indispensable key component of the loom, is mainly responsible for storing and supplying weft yarn in a timely manner to meet the needs of high-speed weft insertion of the loom.

[0003] Currently, the common method for fixing weft feeders on looms is by bolt connection. This involves pre-setting screw holes on the loom frame that match the weft feeder's mounting holes. During installation, the mounting holes of the weft feeder must be precisely aligned with the screw holes on the frame before screws are screwed in and tightened to ensure the weft feeder is securely fixed to the frame. However, this traditional bolt fixing method is inconvenient for installation and disassembly. During routine maintenance, repairs, and equipment upgrades, the weft feeder often needs to be disassembled and reinstalled. Since bolt connections require specialized tools for tightening and loosening, and the operating space is often limited, the entire process is time-consuming and labor-intensive, increasing the workload of maintenance personnel, reducing equipment maintenance efficiency, and consequently affecting the loom's uptime and production efficiency. Furthermore, frequent disassembly and installation of bolts can lead to wear on the screw holes, affecting the installation accuracy and stability of the weft feeder, further impacting the weaving quality.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0028] Please see Figures 1-4 This utility model provides a technical solution: a positioning device for a weft feeder, comprising:

[0029] The main body of the weft feeder includes a driver 1 and a winding disc 2 disposed thereon for winding the yarn;

[0030] The positioning assembly includes a positioning rod 3 vertically disposed at the bottom of the driver 1. The bottom end of the positioning rod 3 is provided with a plurality of positioning claws 4. The positioning claws 4 include an inclined portion 41 rotatably connected to the side wall of the bottom end of the positioning rod 3 and a vertical portion 42 connected to the top surface of the inclined portion 41. A stepped portion 43 is formed at the connection between the inclined portion 41 and the vertical portion 42.

[0031] See Figure 4 A rotating shaft is provided on the outer wall of the bottom end of the positioning rod 3, and a rotating part 44 is connected to the bottom end of the inclined part 41. The rotating part 44 is rotatably connected to the rotating shaft.

[0032] See Figure 4 A torsion spring is fitted on the rotating shaft. One end of the torsion spring is connected to the side wall of the rotating part 44, and the other end of the rotating part 44 is connected to the outer side wall of the positioning rod 3.

[0033] See Figure 3 The top of the positioning rod 3 is provided with a mounting plate 5, which is connected to the bottom surface of the driver 1.

[0034] See Figure 4 The positioning rod 3 has a rotating rod 10 rotatably installed inside it. The bottom end of the rotating rod 10 is connected to a rotating sleeve 12. A steel rope 13 is connected to the top wall of the rotating sleeve 12. The free end of the steel rope 13 passes through the rotating sleeve 12 and is connected to the side wall and inclined part 41 of the positioning rod 3.

[0035] See Figure 4 Both the rotating sleeve 12 and the positioning rod 3 have rope holes 14 on their side walls, and the steel rope 13 is threaded through the rope holes 14.

[0036] See Figure 4 A notch is provided on the side of the positioning rod 3, and a rotating column 11 is fixedly connected to the outer wall of the rotating rod 10. The position of the rotating column 11 corresponds to the notch.

[0037] Specifically, the rotating column 11 makes the rotation of the rotating rod 10 more convenient.

[0038] See Figures 2-4 It also includes an angle adjustment component disposed on the outer wall of the positioning rod 3, the angle adjustment component including,

[0039] Side seat 6 is fixedly connected to the outer wall of positioning rod 3, and connecting rod 7 is rotatably mounted on it;

[0040] The locking head 8 is rotatably connected to the free end of the connecting rod 7, and its other end is locked to the bottom of the driver 1;

[0041] Multiple card slots 9 are equidistantly spaced along the length of the driver 1, and card heads 8 are snapped into the inside of the card slots 9.

Its free end is rotatably connected to the locking head 8. Multiple slots 9 are equidistantly opened at the bottom of the driver 1 along the length direction. When it is necessary to adjust the angle between the positioning rod 3 and the driver 1, the connecting rod 7 is rotated to disengage the locking head 8 from the current slot 9. After adjusting to the appropriate angle, the locking head 8 is then inserted into the corresponding slot 9 to achieve angle locking. The angle adjustment component enables the adjustment of the angle between the positioning rod 3 and the driver 1, allowing the weft feeder to be adjusted to a suitable tilt angle according to different working scenarios and installation requirements, further improving the flexibility and adaptability of the weft feeder positioning and meeting diverse working needs.

[0043] Working principle: The torsion spring drives the inclined part 41, the vertical part 42 and the stepped part 43 to rotate at an angle, so that the positioning rod 3 is fixed in the positioning hole opened on the loom, thereby realizing the installation of the weft feeder body. By rotating the rotating column 11, the rotating rod 10 can be driven to rotate, and the rotating rod 10 drives the rotating sleeve 12 to rotate. The rotation of the rotating sleeve 12 causes the steel rope 13 to be wound on the outer wall of the rotating sleeve 12. During the winding process, the rotating sleeve 12 can pull the inclined part 41 to move closer to the positioning rod 3, thereby facilitating the removal of the positioning rod 3 from the loom and making it convenient to disassemble the weft feeder body.
