Description

Technical Field

[0001] This utility model relates to the field of textile component technology, specifically to a shuttle rotor structure for textile machines that is easy to load and unload. Background Technology

[0002] In the shuttle-feeding mechanism of a loom, the shuttle disc is driven to rotate by a power source, and the shuttle rotor is eccentrically mounted on the shuttle disc. When the shuttle disc rotates, the eccentrically mounted shuttle rotor performs a circular motion, its trajectory deviating from the central axis of the shuttle disc. This design causes the contact point and force direction between the shuttle rotor and components such as the shuttle rod to constantly change during rotation, thereby converting the rotational motion of the shuttle disc into the reciprocating oscillation of the shuttle rod, achieving the throwing action of the shuttle.

[0003] Currently, the shuttle rotor and shuttle disc on the market are fixed by bolts. During long-term operation, the bolt threads wear due to the rotor constantly squeezing against the shuttle rod, making disassembly inconvenient. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a textile machine shuttle rotor structure that is easy to load and unload, thus solving the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a textile machine shuttle rotor structure that is easy to load and unload, including a shuttle disc and a rotor. The shuttle disc is eccentrically provided with a sleeve shaft for connecting the rotor. The inner ring of the rotor is provided with a plurality of positioning holes at equal angles in the circumferential direction. The outer ring of the sleeve shaft is provided with a plurality of sliding holes at equal angles in the circumferential direction. Each sliding hole is fitted with a positioning post that is adapted to the positioning hole. The sleeve shaft is provided with an extrusion mechanism that can push the positioning post out of the positioning hole and into the positioning hole.

[0006] Preferably, the extrusion mechanism includes a pusher shaft and a spring. The pusher shaft has an axially formed guide cavity for sliding. The spring is axially arranged in the guide cavity and its two ends are connected to the bottom of the pusher shaft and the guide cavity. The pusher shaft has a concave ring circumferentially formed. When the pusher shaft moves axially to its limit position, the concave ring corresponds to the sliding hole.

[0007] Preferably, a magnetic ring is provided at the deepest part of the concave ring, and the inner end of the positioning post is a magnetic limiting block that can be attracted to the magnetic ring.

[0008] Preferably, a limiting groove with a diameter larger than that of the sliding hole is provided on the inner wall of the guide cavity, located inside the sliding hole, and the limiting block can be placed in the limiting groove.

[0009] Preferably, the ends of the rotor and the sleeve shaft are respectively provided with arrow one and arrow two corresponding to the positioning hole and the sliding hole.

[0010] Preferably, a locking assembly is further provided between the push shaft and the sleeve shaft. The locking assembly includes a lever, a locking rod, and a second spring. The push shaft has a radial groove for the lever to slide in. The locking rod is radially disposed at one end of the lever. The inner wall of the sleeve shaft has a locking groove for the locking rod to engage. The second spring is radially disposed in the groove and one end is connected to the lever.

[0011] This utility model provides a shuttle rotor structure for textile machines that is easy to load and unload. It has the following beneficial effects:

[0012] 1. The easy-to-install and disassemble textile machine shuttle rotor structure, when pressed axially inward to the corresponding limiting block of the concave ring, the magnetic ring will attract the six limiting blocks, so that the six positioning pins are disengaged from the positioning holes. At this time, the rotor can be removed from the sleeve shaft. Therefore, this application only requires pressing the shaft to quickly complete the disassembly and installation of the rotor, which is very convenient and quick. Attached Figure Description

[0018] This utility model embodiment provides a textile machine shuttle rotor structure that is easy to load and unload, such as... Figure 1-4 As shown, it includes a shuttle disk 1 and a rotor 2, with a sleeve shaft 3 eccentrically arranged on the shuttle disk 1 for connecting the rotor 2.

[0019] The inner ring of the rotor 2 has several positioning holes 6 at equal angles in the circumferential direction. In this embodiment, six positioning holes 6 are used. The outer ring of the sleeve shaft 3 has six sliding holes 7 at equal angles in the circumferential direction. Each sliding hole 7 is fitted with a positioning post 5 that is adapted to the positioning hole 6. The sleeve shaft 3 is provided with an extrusion mechanism that can push the positioning post 5 out of the positioning hole 6 and into the positioning hole 6.

[0020] Specifically, such as Figure 3 As shown, the extrusion mechanism includes a pusher shaft 4 and a spring 9. A guide cavity 8 is axially formed within the sleeve shaft 3, allowing the pusher shaft 4 to slide. The spring 9 is axially positioned within the guide cavity 8, with both ends connecting the pusher shaft 4 and the bottom of the guide cavity 8. When there is no external force, the outer end of the pusher shaft 4 is flush with the outer end of the sleeve shaft 3. A concave ring 10 is circumferentially formed on the pusher shaft 4. When the pusher shaft 4 moves axially inward to its limit position, the concave ring 10 aligns with the sliding hole 7. A transition arc edge is provided between the front and rear sides of the concave ring 10 and the outer wall of the pusher shaft 3. The inner end of the positioning post 5 is a limiting block 12, which is arc-shaped.

[0021] A magnetic ring 11 is disposed at the deepest part of the concave ring 10, and the limiting block 12 is a magnetic body that can be attracted to the magnetic ring 11. The magnetic ring 11 does not use a strong magnet; a magnet with appropriate neutrality can be used. When moving axially along axis 4, the limiting block 12 can slide axially away from the magnetic ring 11. Under normal conditions... Figure 3 As shown, the limiting block 12 is pressed by the outer wall of the pressing shaft 4, causing the outer end of the positioning post 5 to be pushed into the positioning hole 6, thereby locking the rotor 2. When the pressing shaft 4 is pressed inward to the position of the concave ring 10 corresponding to the limiting block 12, the magnetic ring 11 will attract the six limiting blocks 12, causing the six positioning posts 5 to disengage from the positioning hole 6. At this time, the rotor 2 can be removed from the sleeve shaft 3.

[0022] A limiting groove 20 with a diameter larger than that of the sliding hole 7 is provided on the inner wall of the guide cavity 8, located inside the sliding hole 7. The limiting block 12 can be placed in the limiting groove 20. The diameter of the limiting block 12 is larger than that of the sliding hole 7. By providing the limiting groove 20, the positioning post 5 can be prevented from sliding out of the sliding hole 7.

[0023] like Figure 2 As shown, to facilitate quick alignment of the positioning hole 6 and the positioning post 5, the ends of the rotor 2 and the sleeve shaft 3 are respectively provided with arrow 18 and arrow 19 corresponding to the positioning hole 6 and the sliding hole 7. During installation, simply align arrow 18 on the rotor 2 with arrow 19 on the sleeve shaft 3 to quickly install the rotor 2.

[0024] like Figure 4 As shown, a locking assembly is also provided between the pressing shaft 4 and the sleeve shaft 3. By providing the locking assembly, the pressing shaft 4 can be prevented from being disturbed by external forces during the use of the rotor 2. Figure 4As shown, the locking assembly includes a lever 13, a locking rod 15, and a second spring 17. A radial groove 14 is provided on the shaft 4 for the lever 13 to slide. The locking rod 15 is radially positioned at one end of the lever 13. A slot 16 is provided on the inner wall of the shaft 3 for the locking rod 15 to engage. The second spring 17 is radially positioned within the groove 14, with one end connected to the lever 13. Under normal conditions, the lever 13, under the action of the second spring 17, holds the locking rod 15 within the slot 16, achieving axial locking of the shaft 4. When the rotor 2 needs to be disassembled, the lever 13 is first moved laterally to disengage the locking rod 15 from the slot 16, and then the shaft 4 is pressed down. Both the movement of the lever 13 and the pressing of the shaft 4 can be performed with one hand, making the operation very convenient.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
