DETAILED DESCRIPTION
[0018] The utility model will be explained in detail in combination with the drawings as follows:
[0019] As shown in the figure: curtain knitting machine knotter, including fixed sheet 61, pneumatic knotter 62, adjusting mechanism 63, wire pressing mechanism 64, cutting knife 65; Figures 1-6
[0020] Fixed sheet 61 is equipped with two, and the opposite faces of the two fixed sheets 61 are all installed with pneumatic knotter 62, and cutting gap is equipped between the two pneumatic knotters 62;
[0021] Adjusting mechanism 63 is installed between the two fixed sheets 61, and the upper part of adjusting mechanism 63 is installed with wire pressing mechanism 64 and cutting knife 65, and two wire pressing mechanisms 64 are separately arranged on the two sides of cutting knife 65, and two wire pressing mechanisms 64 are pressed on the corresponding pneumatic knotter 62 after being adjusted through adjusting mechanism 63, and cutting knife 65 moves to cutting gap;
[0022] Among them, the upper edge of fixed sheet 61 is provided with guide groove 611, and the upper surface of pneumatic knotter 62 is provided with wire guide groove 622 through air outlet 621.
[0023] The fixed sheet here is essentially a mounting carrier, mainly used for mounting and positioning other components; the pneumatic knotter needs to be externally connected to a gas supply device, but this is a conventional technology, and the specific usage will not be described here; the purpose of the adjustment structure is mainly to control the line pressing mechanism and the cutting knife. Since the rope used for binding is in a state of tension, if it is cut directly, the rope will be directly pushed away to both ends due to elasticity. By using the line pressing mechanism, the rope can be pressed against the pneumatic knotter 62, ensuring that the knotted rope remains on the pneumatic knotter, making it easier to arrange later. The guide groove 611 and the wire guide groove 622 are used to guide the rope used for binding, and the wire guide groove 622 mainly provides a channel for the exhaust of the gas flow during the exhaust of the air outlet hole 621.
[0024] Among them, according to the position relationship and structure of the adjustment mechanism 63, the utility model derives the following three embodiments:
[0025] Embodiment 1
[0026] As shown in Figures 1-3 : The adjustment mechanism 63 includes a first swing arm 631, a rotating shaft 632, a bearing 633, and a rotating motor. The bottom end of the first swing arm 631 is connected to the rotating shaft 632, the bearing 633 is installed on the two fixed sheets 61, the rotating shaft 632 passes through the bearing 633 and is connected to the rotating motor, and the motor rotating motor is on the outside of one of the fixed sheets.
[0027] Among them, the first swing arm 631 is located in front of the pneumatic knotter 62.
[0028] As can be seen from Figure 3 , by driving the first swing arm, the line pressing mechanism can be tightly attached to the pneumatic knotter 62 and the procedure of cutting the rope is completed. Here, the swing arm method is used to allow the cutting knife to produce a forward and backward cutting effect, making it easy to cut the rope.
[0029] The upper part of the first swing arm 631 is bent backward, and the cutting knife 65 is installed at the bent part. A spring fixing plate 67 is also installed at the bent part of the first swing arm 631, and the line pressing mechanism 64 is installed on the spring fixing plate 67.

[0039] It should be noted that the cutting edge of the cutting knife also needs to be designed as an inclined cutting edge.
[0040] The other end of the telescopic arm 639 is also provided with a spring fixing plate 67, and the wire pressing mechanism 64 is installed on the spring fixing plate 67. The spring fixing plate 67 is mainly used to facilitate the installation of the wire pressing mechanism 64.

[0043] A wire guide groove 661 is formed in the upper edge of any wire clamping baffle 66. The wire clamping baffle 66 is mainly used to clamp the binding wire, so that the binding wire cannot be loosened at both ends after being cut by the cutting knife.
