[0002] A search revealed that the existing technology with announcement number CN222989455U has the following general solution: It includes a main shaft, on which a driving synchronous pulley is mounted. The driving synchronous pulley is connected to a driven synchronous pulley via a belt. A driven shaft passes through the driven synchronous pulley, and an eccentric sleeve is mounted on the driven shaft. The eccentric sleeve is connected to a first connecting rod, which is connected to a first joint. It also includes a rocker arm plate connected to the wire frame pushing device, rotatably mounted on a mounting frame, with the first joint rotatably connected to the rocker arm plate. While it offers advantages such as stable transmission, high efficiency, and controllable transmission speed, the eccentric structure of the pushing mechanism is prone to wear and requires timely replacement. Therefore, a pushing structure that is easy to maintain and replace is preferred. Summary of the Invention

Both ends of the needle shaft, located on the outer side of the mounting frame, are connected to the needle pusher frame via a first transmission rod; both ends of the pusher shaft, located on the outer side of the mounting frame, are connected to the pusher frame via a second transmission rod; the first main shaft drives the needle pusher shaft and the pusher shaft to rotate, causing the needle pusher frame and the pusher frame to slide upward or downward on the support frame; the needle pusher shaft is connected to a second core sleeve provided inside the first transmission rod; wherein, the second core sleeve is movably connected to the first transmission rod, and the second core sleeve has an eccentric structure.

[0005] As a preferred technical solution of the present invention: the mounting bracket is further provided with a second main shaft, and the first main shaft and the second main shaft are connected by a coupling.

[0006] As a preferred technical solution of the present invention: the pusher frame is further provided with a first connecting rod, which passes through the first guide member provided on the support frame and is connected to the first transmission rod.

[0007] As a preferred technical solution of the present invention: the pusher holder is connected to the second transmission rod after passing through the second guide member provided on the support frame via a second connecting rod.

[0008] As a preferred embodiment of the present invention: the upper end of the second transmission rod is connected to a clamping pin, and the other end of the clamp is clamped on the second connecting rod.

[0009] As a preferred embodiment of the present invention: the second transmission rod is connected to the pusher shaft through a first core sleeve and is connected to the first core sleeve through a first clamping plate, so as to fix one end of the second transmission rod on the pusher shaft.

[0022] Please see Figure 1-5An embodiment of the present invention provides a textile machine, including a frame 1 and a swing assembly 2 mounted on the frame 1. The swing assembly 2 includes a support frame 20, with a needle pusher frame 21 and a knife pusher frame 22 above the support frame 20. A pushing structure 29 is also provided below the support frame 20. The pushing structure 29 includes a mounting frame 214 and a first main shaft 210 mounted on the mounting frame 214. The mounting frame 214 is also provided with a knife pusher shaft 215 and a needle pusher shaft 216, and both the knife pusher shaft 215 and the needle pusher shaft 216 are provided with driven wheels 217. The driven wheels 217 are connected to a driving wheel 211 provided on the first main shaft 210. The driving wheel 211 and the driven wheel 217 are connected by a belt. Specifically, the driving wheel 211 and the driven wheel 217 are preferably synchronous wheels, and the belt is preferably a synchronous belt, so that the needle pusher shaft 216 and the knife pusher shaft 215 can rotate synchronously with the first main shaft 210. When the push needle shaft 216 and the push knife shaft 215 rotate synchronously with the first main shaft 210, the push needle shaft 216 and the push knife shaft 215 are driven to rotate by the first main shaft 210, so that the push needle holder 21 and the push knife holder 22 slide up or down on the support frame 20.

[0023] Furthermore, since both ends of the pusher shaft 216, located on the outside of the mounting bracket 214, are connected to the pusher frame 21 via a first transmission rod 27; and both ends of the pusher shaft 215, located on the outside of the mounting bracket 214, are connected to the pusher frame 22 via a second transmission rod 28; therefore, the first transmission rod 27 and the second transmission rod 28 are positioned on the outside of the mounting bracket 214 to facilitate user disassembly and assembly, improve the convenience of maintenance, and thus facilitate the maintenance of vulnerable parts. In particular, the pusher shaft 216 is connected to the second core sleeve 271 provided inside the first transmission rod 27; wherein, the second core sleeve 271 is movably connected to the first transmission rod 27, and the second core sleeve 271 has an eccentric structure, so the movement amplitude can also be adjusted by changing the size of the second core sleeve 271. For example, by increasing the diameter of the second core sleeve 271, the center of the pusher shaft 216 and the center of the second core sleeve 271 are enlarged, thus increasing the movement amplitude. When a smaller size second core sleeve 271 is selected, the distance between the center of the pusher shaft 216 and the center of the second core sleeve 271 is reduced, thus reducing the movement amplitude.

[0024] To facilitate the installation and replacement of the belt, a second main shaft 213 is provided inside the mounting bracket 214, and the first main shaft 210 and the second main shaft 213 are connected by a coupling 212. Therefore, when the belt is damaged, the coupling 212 can be disassembled to separate the first main shaft 210 and the second main shaft 213, so that the belt can be inserted into the drive pulley 211 through the gap between the two main shafts. Based on this, the installation and replacement of the belt is simple and convenient.

[0025] To ensure that the needle pusher 21 slides stably and reliably upward or downward, the needle pusher 21 is also provided with a first connecting rod 23. The first connecting rod 23 passes through the first guide member 25 provided on the support frame 20 and is connected to the first transmission rod 27.

[0026] To ensure that the pusher holder 22 slides stably and reliably upward or downward, the pusher holder 22 is connected to the second transmission rod 28 after passing through the second guide member 26 provided on the support frame 20 via the second connecting rod 24.

[0027] In summary, the sliding engagement between the first guide member 25 and the first connecting rod 23 can guide the directional sliding of the pusher pin holder 21, and the sliding engagement between the second guide member 26 and the second connecting rod 24 can guide the directional sliding of the pusher pin holder 22; wherein, the first guide member 25 and the second guide member 26 are preferably linear bearings.

[0028] To facilitate the connection and disassembly of the second transmission rod 28 and the second connecting rod 24, the upper end of the second transmission rod 28 is pin-connected to a chuck 281, and the other end of the chuck 281 is clamped onto the second connecting rod 24. Specifically, one end of the chuck 281 is connected to the upper end of the second transmission rod 28 using a pin. Then, the lower end of the second connecting rod 24 is inserted into the connecting hole 284 on the chuck 281. Fasteners such as bolts are then passed through the internal threaded holes on the chuck 281, causing the connecting hole 284 to grip the second connecting rod 24, thus completing the connection between the second connecting rod 24 and the second transmission rod 28. Simultaneously, disassembling the fasteners on the internal threaded hole 285 releases the second connecting rod 24, facilitating the disassembly of the chuck 281 and the second connecting rod 24. This makes the disassembly and assembly of the second transmission rod 28 and the pusher holder 22 simple and convenient, allowing the second transmission rod 28 to be easily removed from the pusher holder 22.

[0029] Furthermore, since the second transmission rod 28 is connected to the pusher shaft 215 via a first core sleeve 283 and to the first core sleeve 283 via a first clamping plate 282, one end of the second transmission rod 28 is fixed to the pusher shaft 215. Therefore, connecting and disassembling the second transmission rod 28 to the pusher shaft 215 is simple and convenient. Specifically, when one end of the pusher shaft 215 is inserted into the first core sleeve 283, a fastener passes through the first clamping plate 282 and connects to the first core sleeve 283, thus completing the connection between the pusher shaft 215 and the second transmission rod 28. Conversely, disassembling the first clamping plate 282 allows for the disassembly of the second transmission rod 28 to the pusher shaft 215. Based on this, the assembly and disassembly of the second transmission rod 28 to the pusher shaft 215 are simple and convenient, facilitating the installation and replacement of the second transmission rod 28.

[0030] Alternatively, the operating range of the pusher holder 22 can be adjusted by selecting different first core sleeves 283.

[0031] Based on the above solution, since the first spindle 210, the second spindle 213, the pusher shaft 216 and the pusher shaft 215 are all connected to the mounting bracket 214 through the provided bearing seat 218, the installation of each shaft is simple and convenient.

[0032] Furthermore, both ends of the pusher shaft 216 are provided with shaft pins 219, and the shaft pins 219 are eccentrically set with the pusher shaft 216, so that the pusher shaft 216 can be easily and conveniently connected to the second core sleeve 271.

[0033] Furthermore, since the second core sleeve 271 is also equipped with a ball bearing 270, and the outer ring of the ball bearing 270 is connected to the pin hole 275 on the first transmission rod 27, and is confined within the pin hole 275 by a retaining ring 273, the installation and replacement of the second core sleeve 271 are simple and convenient. Simply remove the retaining ring 273 from the pin hole 275 and push the second core sleeve 271 to the right to separate it from the first transmission rod 27. Therefore, the operating range of the pusher pin holder 21 can be adjusted by replacing different second core sleeves 271. The first core sleeve 283 has the same structure as the second core sleeve 271.

[0034] Furthermore, after the second core sleeve 271 is connected to the shaft pin 219, the second core sleeve 271 is fixed to the shaft pin 219 by the provided second clamping plate 272. Therefore, the assembly and disassembly of the second core sleeve 271 and the shaft pin 219 are simple and convenient. In particular, the end of the second core sleeve 271 away from the shaft pin 219 is also provided with an annular groove 274. Therefore, a retaining ring can be used to hold the ball bearing 270 on the second core sleeve 271 by being held in the annular groove 274. Conversely, the ball bearing 270 can be replaced by disassembling the retaining ring.

[0035] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and these variations still fall within the protection scope of the present invention.
