The wire end is pulled by the winding end, and the sub-wires or yarns are separated from multiple wire devices. Then relevant technicians (for example: workers) are required to stop the machine for threading, thereby reducing the braiding efficiency. Utility Model Content

Detailed implementation manners
[0022] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.
[0023] The broken - wire capturing mechanism of the knitting machine according to the embodiment of the present utility model will be described below with reference to the drawings.
[0024] As Figures 1-5 shown, the broken - wire capturing mechanism of the knitting machine according to the embodiment of the present utility model may include a frame body 1, an auxiliary component 2, a wire - guiding roller shaft 3, a capturing component 4, and a connection component 5.
[0025] Among them, the auxiliary component 2 is arranged on the frame body 1, and the wire - guiding roller shaft 3 is rotatably connected inside the frame body 1.
[0026] It should be noted that the auxiliary component 2 described in this embodiment is connected to an external control device (not shown in the figure). The auxiliary component 2 can monitor the broken - wire situation and transmit the monitoring signal to the external control device, and the external control device sends a signal to the capturing component 4.
[0027] The capturing component 4 is located below the wire - guiding roller shaft 3. The capturing component 4 includes a cylinder 41, a connecting push - plate 42, and a wire - pressing member 43.
[0028] Among them, the cylinder 41 is installed on the inner bottom wall of the frame body 1. The connecting push - plate 42 is arranged between the telescopic end of the cylinder 41 and the wire - pressing member 43, and the wire - pressing member 43 is slidably connected to the frame body 1.
[0029] It should be noted that the shape of the wire pressing member 43 described in this embodiment is adapted to that of the wire guiding roller 3, and the two can be closely attached to ensure that the broken wire can be fixed between the wire pressing member 43 and the wire guiding roller 3.
[0030] The connecting assembly 5 is arranged on the frame 1.
[0031] It should be noted that relevant technical personnel (such as workers) can use the connecting assembly 5 to install multiple such catching mechanisms on the knitting machine, and the position and quantity of such catching mechanisms can be set according to the path of wire transmission.
[0032] Specifically, the worker uses the connecting assembly 5 to install multiple such catching mechanisms on the knitting machine. At one such catching mechanism, the sub-wire bypasses the wire guiding roller 3 after passing through the auxiliary assembly 2 and moves.
[0033] If the auxiliary assembly 2 detects the occurrence of a broken wire, the auxiliary assembly 2 sends a signal to an external control device, and the external control device sends an operation signal to the cylinder 41 in the catching assembly 4. The cylinder 41 instantly pushes the connecting push plate 42 and the wire pressing member 43 to abut against the outer side of the wire guiding roller 3, and the wire end of the broken wire is fixed between the wire pressing member 43 and the wire guiding roller 3, preventing the broken wire from separating from other wire devices, thus saving the wire threading time and improving the knitting efficiency. Then the knitting machine stops and gives a reminder to the worker.
[0034] The worker pulls both ends of the broken wire and presses a reset key (not shown in the figure), the catching assembly 4 resets, and the worker connects the broken wire and continues the knitting operation.
[0035] In an embodiment of the present invention, as Figure 2 shown, a second through groove 44 is formed in the wire pressing member 43.
[0036] It should be noted that the shape of the second through groove 44 described in this embodiment is adapted to that of the wire guiding roller 3.
[0037] It can be understood that when the wire pressing member 43 abuts against the outer wall of the wire guiding roller 3, the sub-wire in the middle of the wire pressing member 43 is suspended, and the frictional force between the sub-wire and the wire pressing member 43 is greater.
[0038] In an embodiment of the present invention, as Figure 1 and Figure 4 shown, the auxiliary assembly 2 includes a bracket 21, an auxiliary wire wheel 22, a shaft body 23, two auxiliary blocks 24, and a pressure sensor 25.
[0039] Among them, the bracket 21 is installed on the inner top wall of the frame 1, the auxiliary wire wheel 22 is rotatably connected to the shaft body 23, both ends of the shaft body 23 are respectively connected to the bracket 21 through the two auxiliary blocks 24, and the pressure sensor 25 is arranged between the auxiliary block 24 and the bracket 21.
[0040] It should be noted that under normal circumstances, when the sub-line passes around the auxiliary line wheel 22, a force will be applied to it. The pressure sensor 25 can monitor this pressure. When the pressure sensor 25 detects that the force is reduced instantaneously, it can be determined as a line break and a signal can be sent to the external control device.
[0041] In one embodiment of the present invention, Figure 1 and Figure 3 As shown, two cavities 31 are symmetrically arranged inside the frame 1 , and a first through slot 32 is opened on the side wall of the cavity 31 .
[0042] A moving block 33 is slidably connected in the cavity 31 , and buffer rods 35 are respectively provided above and below the moving block 33 . Both ends of the wire roller 3 pass through the corresponding first through slots 32 , and one end of the wire roller 3 is rotatably connected to the moving block 33 .
[0043] It is understandable that under the action of the buffer rod 35, the conductor roller 3 can play the role of tightening the sub-wire, and the buffer rod 35 can adapt to the jumping of the sub-wire during its own transmission process, reducing the misjudgment of the auxiliary component 2 during the pressure monitoring process.
[0044] In one embodiment of the present invention, Figure 1 and Figure 5 As shown, the connecting assembly 5 includes a fixed plate 51 , a movable plate 53 and a screw rod 54 .
[0045] The fixed plate 51 is provided with a plurality of fixing holes 52 , the movable plate 53 is connected to the frame 1 , the screw rod 54 is disposed on the fixed plate 51 , and the screw rod 54 is threadedly connected to the movable plate 53 .
[0046] In one embodiment of the present invention, Figure 1 and Figure 5 As shown, two guide blocks 61 are symmetrically arranged on the moving plate 53 , and two clamping grooves 62 are symmetrically opened on the frame body 1 , and the guide blocks 61 are slidably connected to the clamping grooves 62 .
[0047] Specifically, the capture mechanism can adjust the position of the connecting component 5 on the frame 1 according to the specific installation position on the braiding machine, so that the sub-line can bypass the wire roller 3, push the movable plate 53, and the guide block 61 slides inside the slot 62. After reaching the preset position, the fixed plate 51 is rotated, and the fixed plate 51 drives the screw 54 to rotate. The screw 54 is threadedly connected to the movable plate 53, so that the guide block 61 is engaged in the slot 62 to fix the connecting component 5 on the frame 1.
[0048] In summary, for the broken wire capturing mechanism of the knitting machine of the present utility model, when the auxiliary component monitors the occurrence of a broken wire situation, the air cylinder drives the pressing member to abut against the wire guiding roller shaft through the connecting push plate, and the broken wire is fixed between the pressing member and the wire guiding roller shaft, preventing the broken wire from detaching from other wire devices, saving the threading time, and improving the knitting efficiency.
