[0060] Among them, see Figure 2 As shown, the puncture needle disk assembly 27 of this embodiment can rotate around the puncture needle disk rotating shaft 22 as the axis. Figure 1 and Figure 2 As shown, see Figure 2 As shown, the needle disc assembly 27 rotates in a horizontal plane with the needle disc rotating shaft 22 as the axis (the needle disc assembly 27 can also move up and down along the axial direction of the needle disc rotating shaft 22), and can rotate to a receiving position and a suturing position, wherein the receiving position refers to the needle disc assembly 27 receiving the semi-finished product on the needle cylinder 24 of the hosiery machine 25, and the suturing position refers to the needle disc assembly 27 swinging back to a position where it can be positioned with the clutch body, and in this position, the needle disc assembly 27 can rotate and sew the sock head under the drive of the gear disc 37. The needle disc assembly 27 can rotate in a horizontal plane under the drive structure of the motor gear, and can reciprocate in a vertical plane under the drive of a transmission structure such as a worm gear (horizontal rotation and vertical movement are both prior art, which will not be described in detail here).

[0061] When the clutch body and the clutch gear 7 are in a disengaged state, the puncture needle disk assembly 27 rotates in a horizontal plane with the puncture needle disk rotating shaft 22 as the axis, rotates to the receiving position, and then receives the semi-finished product on the needle cylinder 24 of the hosiery machine 25; when the puncture needle disk assembly rotates to the suture position and the external force acting on the fork 6 is removed, under the action of the reset elastic member 14, the clutch body and the clutch gear 7 are positioned and connected, and the two are in a transmission state, and the driving device 1 can drive the gear 2 to rotate through the clutch body and the clutch gear 7, and the puncture needle disk assembly 27 rotates synchronously with the gear disk 37.

[0063] The telescopic pin 5 is fixed to the telescopic end of the cylinder 3, and the telescopic pin 5 reciprocates in the vertical direction under the drive of the cylinder 3. Figure 5 , Figure 8 , Fig.12 and Fig.13 As shown, when the telescopic pin 5 is in the extended state, it can press the second end of the fork 6, the fork 6 rotates, the first end of the fork 6 tilts up, the clutch body moves up, and the clutch body and the clutch gear 7 are in a disengaged state; when the telescopic pin 5 retracts, the fork 6 is reset, the clutch body moves down, and the clutch body (specifically the clutch seat 16) is repositioned and transmission-connected with the clutch gear 7. The above structure can realize the automatic disengagement or transmission connection between the clutch body (clutch seat 16) and the clutch gear 7.

[0064] As an alternative embodiment, see Figure 5-Figure 13 As shown, the clutch body includes a shaft 9 and a clutch seat 16, wherein: the fixed platform 26 includes a bracket 17, and the fork 6 is rotatably connected to the bracket 17; the driving device 1 is transmission-connected to the shaft 9, the clutch seat 16 is sleeved on the lower end of the shaft 9, the clutch seat 16 is slidably connected to the shaft 9 in the axial direction, and both can rotate synchronously around the axis of the shaft 9; the first end of the fork 6 is fixedly connected to the clutch seat 16, and the fork 6 can rotate when the second end thereof is pressed by an external force, and drive the clutch seat 16 to move upward along the axial direction of the shaft 9, thereby The clutch seat 16 is disengaged from the clutch gear 7; when the puncture needle disk assembly 27 is rotated to the suturing position and the external force acting on the fork 6 is removed, the clutch seat 16 can be inserted and positioned in the clutch gear 7, and the clutch seat 16 and the clutch gear 7 are in a transmission state; the clutch body also includes a reset elastic member 14, which is sleeved on the shaft 9, one end of the reset elastic member 14 is fixed on the shaft 9, and the other end is against the clutch seat 16, and the reset elastic member 14 is used to drive the clutch seat 16 to reset. The output end of the driving device 1 is provided with a driving gear 2, and the shaft 9 is outer-mounted and fixed with a driven gear 12, and the driving gear 2 is meshed with the driven gear 12, and is used to drive the shaft 9 and the clutch seat 16 to rotate synchronously around the axis of the shaft 9. The driving device 1 can be a motor.

[0065] See also Figure 7 and Figure 8As shown, in this embodiment, the shaft 9 can be a spline shaft, and the spline shaft outer sleeve is provided with a spline shaft sleeve 10, the spline shaft sleeve 10 is fixedly connected to the driving gear 2, and the driven gear 12 is rotatably connected to the bracket 17 through the gear bearing 11, so as to realize the synchronous rotation of the driving gear 2 and the shaft 9. A spline shaft locating ring 13 is fixed to the outside of the shaft 9, and the spline shaft locating ring 13 is fixed by the fixing nut 4, and a plane bearing 15 is also sleeved on the outside of the shaft 9.

[0066] In this embodiment, the clutch seat 16 can move axially along the shaft 9, and the clutch seat 16 can rotate synchronously with the shaft 9 with the axis of the shaft 9 as the axis. In this way, the drive device 1 drives the shaft 9 and the clutch seat 16 to rotate through the driving gear 2 and the driven gear 12, and the clutch seat 16 can be positioned in the clutch gear 7, thereby realizing the rotation of the clutch gear 7, and the rotation of the clutch gear 7 also drives the gear plate 37 to rotate, thereby realizing the synchronous rotation of the puncture needle disk assembly 27 and the gear plate 37, and sewing the sock head. When the fork 6 is pressed, the clutch seat 16 can move axially along the shaft 9, the clutch seat 16 moves up, and disengages from the clutch gear 7. At this time, the drive device 1 cannot drive the clutch gear 7 to rotate, the gear plate 37 does not rotate, and the puncture needle disk assembly 27 cannot rotate to sew the sock head.

[0067] As an alternative embodiment, see Figure 5 The shift fork 6 includes a pressing plate 61, a fork body 62 and a connecting plate 63, wherein: the opposite ends of the connecting plate 63 are fixedly connected to the pressing plate 61 and the fork body 62 respectively, the connecting plate 63, the pressing plate 61 and the fork body 62 are in a bent structure, the pressing plate 61 is rotatably connected to the bracket 17, and the two fork rods of the fork body 62 are respectively located on the opposite sides of the clutch seat 16 and fixedly connected to the clutch seat 16; the pressing plate 61 is an inclined plate, and more than two shaft holes 64 are arranged on the inclined plate, and the rotating shaft of the shift fork 6 can pass through different shaft holes 64 and be fixed on the bracket 17, thereby adjusting the height of the shift fork 6.

[0068] The shift fork 6 of this embodiment can rotate under the pressing action of the telescopic pin 5, thereby driving the clutch seat 16 to move along the shaft 9, and realizing the transmission or disengagement of the clutch seat 16 and the clutch gear 7. The structure is simple, and the clutch gear 7 can be rotated or not rotated, thereby realizing the rotation or non-rotation of the gear plate 37.

[0069] In this embodiment, at least part of the clutch seat 16 is inserted into the clutch gear 7, and the transmission connection between the two can be achieved through the following structure:

[0070] See also Fig. 9 and Fig.10As shown, the clutch seat 16 is provided with an alignment convex head 33, and the clutch gear 7 is provided with an alignment concave hole 34 at the center position, wherein: a latch 32 is fixed on the clutch seat 16, the latch 32 is located beside the alignment convex head 33, and a pin groove 35 is provided on the clutch gear 7; when the clutch body and the clutch gear 7 are in a transmission state, the alignment convex head 33 is inserted into the alignment concave hole 34 for center positioning, and the latch 32 is inserted into the pin groove 35, so that the clutch body and the clutch gear 7 rotate synchronously.

[0071] In this embodiment, the alignment convex head 33 and the latch pin 32 are located at the same end of the clutch seat 16, and the bottom end of the alignment convex head 33 is at a lower horizontal position. When the clutch seat 16 moves downward, the alignment convex head 33 is first inserted into the alignment concave hole 34 of the clutch gear 7 to achieve the center positioning of the clutch seat 16 and the clutch gear 7. Then, as the clutch seat 16 continues to move downward, the latch pin 32 is inserted into the pin groove 35. The latch pin 32 can be a wedge-shaped block. When the latch pin 32 is inserted into the pin groove 35, the clutch body and the clutch gear 7 are in a transmission state, and the clutch seat 16 drives the clutch gear 7 to rotate. Since the clutch gear 7 is engaged with the gear plate 37, as shown in FIG. Fig.14 As shown, therefore, the gear plate 37 rotates synchronously at this time.

[0072] The above description is about the structure when the clutch body and the clutch gear 7 are in the transmission state. When the clutch body and the clutch gear 7 are in the disengagement state, in order to ensure the structural stability of the clutch body, as an optional implementation method, see Figure 5 and Figure 6 As shown, an annular positioning block 18 is provided on the clutch seat 16, and the annular positioning block 18 is arranged concentrically with the clutch seat 16. A positioning groove 31 is opened on the positioning block 30, and the notch of the positioning groove 31 is arranged away from the axis of the clutch seat 16; the positioning block 30 is fixedly arranged on the fixed platform 26, and when the clutch body and the clutch gear 7 are in a disengaged state, the positioning block 30 is inserted into the positioning groove 31.

[0073] See also Figure 5 As shown, when the puncture needle disk assembly 27 is rotated to the suturing position, the puncture needle disk assembly 27 and the gear disk 37, and the gear disk 37 and the fixed platform 26 are positioned, and the clutch body and the clutch gear 7 are in a disengaged state, the clutch seat 16 moves up until the positioning block 30 is inserted into the positioning groove 31, see Figure 5 and Figure 6 As shown, the stability of the clutch body structure is improved.

[0074] Since the puncture needle disk assembly 27 can rotate around the puncture needle disk rotating shaft 22, how to ensure that when the puncture needle disk assembly 27 rotates to the suture position, the alignment protrusion 33 is just inserted into the alignment concave hole 34 and the latch 32 is inserted into the pin groove 35, so that the clutch body (clutch seat 16) and the clutch gear 7 rotate synchronously, is achieved by the following structure:

[0075] See also Figure 1 , Figure 2 and Figure 4 As shown, the clutch transmission device of the puncture needle disk assembly 27 also includes a positioning assembly, and the positioning assembly and the clutch body are located on opposite sides of the gear disk 37. The positioning assembly is used to ensure that the clutch body is positioned and connected with the clutch gear 7; see Figure 2 As shown, the clutch body is located on the opposite side of the positioning assembly. Figure 2 The middle clutch assembly and its installation position A are the best positions. The clutch assembly includes a shift fork 6, a clutch body and a clutch gear 7.
