On the side of the rocker plate C2-55, there is a hook 2-56;

[0051] Among them, the rope winding module 2-6 includes a long fixing plate 2-61 fixedly installed on the lower surface of the driven wheel. In the middle of the right surface of the long fixing plate 2-61, a mounting shaft D2-62 is provided. A rocker plate A2-63 is sleeved on the mounting shaft D. In front of the rocker plate A2-63, a connecting plate 2-64 is fixedly installed. The other end of the connecting plate 2-64 is fixedly installed on the rocker plate B2-65. The other end of the rocker plate B2-65 is rotatably installed on a mounting shaft E2-66. The mounting shaft E2-66 passes through the long fixing plate 2-61, the rope threading block 2-67 and a pressing rope block 2-68 is installed below it,

[0052] One end of the pressing rope block 2-68 is fixedly connected to the mounting shaft E2-66, and the other end is installed at the lower end of the rope threading block 2-67. The pressing rope block 2-68 is a wedge-shaped block and there is a gap between it and the rope threading block 2-67;

[0053] Behind the rocker plate A2-63, a spring 2-70 is installed. The other end of the spring 2-70 is installed on a fixing block 2-69 on the lower surface of the driven wheel;

[0054] As Figure 7 Schematic diagram of the structure of the mounting shaft E2-66 shown. The mounting shaft E2-66 includes a shaft body. On the shaft body, there is a mounting groove for installing the pressing rope block 2-68. On the shaft body corresponding to the mounting groove, there is a mounting hole A;

[0055] As Figure 8Schematic structural diagram of the rope threading block 2-67 shown. The rope threading block 2-67 is a rectangular block. On one side of the rope threading block 2-67 facing the long fixed plate 2-61, there is a long fixed plate mounting groove 2-671. On the rope threading block 2-67, there is a mounting shaft hole 2-672 for mounting the mounting shaft E2-66.

The mounting shaft E2-66 is installed in the mounting shaft hole 2-672. One end of the mounting shaft E2-66 extending out of the mounting shaft hole is fixedly installed with the pressing rope block 2-68. The pressing rope block 2-68 is located in the pressing rope mounting groove 2-673.

[0056] In the initial state, the piston rod of the hook driving cylinder is extended. When the bag clamping assembly clamps the packaging bag, the rope winding motor starts, drives the driven wheel to rotate through the transmission mechanism, and the driven wheel drives the rope winding module to rotate. When the rope winding module bypasses the packaging bag, the hook, and the extension block, at this time, the hook and the extension block are in a closed state. The rope extending cylinder starts, the piston rod extends, drives the mounting shaft B to move downward, and the mounting shaft B drives the fixed seat B to rotate clockwise. When it rotates a certain angle, the nylon rope falls off the hook. After the nylon rope falls off the hook, the rope extending cylinder retracts, drives the fixed seat B back to the original state, and the rope winding module continues to rotate. The nylon rope only bypasses the packaging bag to complete the first circle of winding. After completing the first circle of winding, the rope winding module continues to rotate, and the nylon rope still bypasses the outside of the packaging bag and the hook to complete the second circle of winding. When the rope winding module rotates to the hook, that is, when it rotates half a circle, the hook driving cylinder starts, the piston rod retracts, drives the rocker plate C to rotate counterclockwise, that is, the hook moves away from the extension block, that is, there is a certain distance between the two. At this time, the nylon rope falls between the hook and the extension block. Then the hook driving cylinder extends the piston rod, drives the rocker plate C to rotate clockwise, that is, the hook approaches the extension block, and the two clamp the nylon rope. After clamping, the rope winding module rotates in the reverse direction, the rope extending cylinder starts, and the nylon rope extends out from the gap between the hook and the extension block, that is, from the circle formed by the second circle, to complete the knotting. When the rope winding module rotates half a circle in the reverse direction, the piston rod of the rope extending cylinder retracts, and the piston rod of the hook driving cylinder also retracts, and the nylon rope is loosened, and the knotting is completed.

[0057] Among them, as Figure 9The bag clamping assembly 3 shown includes a descending cylinder 3-1 mounted on the power mounting plate 1. Guide rails 3-2 are provided on both sides of the descending cylinder 3-1. A center plate 3-3 is mounted at the output end of the descending cylinder. A clamping cylinder 3-4 is mounted in the middle of the center plate 3-3. A fixed support plate 3-5 is mounted on the piston rod of the clamping cylinder 3-4. 3-6 groups of crescent plates 3-6 are evenly distributed around the fixed support plate 3-5.

One of them is a fork mounting hole for mounting the fork, and the other is a crescent plate mounting hole for mounting on the crescent plate. The clamping jaw is located between the two crescent plates.

[0061] The initial state of the bag clamping assembly is that the piston rod of the clamping cylinder extends. The piston rod drives the fixed support plate to move downward. The crescent plate rotates counterclockwise under the drive of the fixed support, and at the same time drives the clamping jaw to rotate counterclockwise, that is, the clamping jaw opens. When the clamping cylinder is activated, the piston rod retracts. The piston rod drives the fixed clamping plate to move upward. The crescent plate rotates clockwise under the drive of the fixed support, and at the same time drives the clamping jaw to rotate clockwise. The clamping jaws move closer to the middle, that is, the clamping jaws close, and the bag mouth of the packaging bag is clamped.

[0062] Among them, the rope cutting assembly 4 includes a threading module 4-1, a tensioning drive module 4-2 and a cutting module 4-3,

[0063] The string threading module 4-1 includes a support plate 4-11. At one end of the support plate 4-11, a string threading frame A 4-12 is installed. At the other end of the support plate 4-11, an extension plate 4-13 is fixedly installed, and a string threading frame B 4-14 is installed on the extension plate 4-13;

[0064] The tensioning drive module 4-2 includes an L-shaped plate B 4-21 installed on the power mounting plate 1. A press wheel cylinder 4-22 is fixedly installed on the vertical plate of the L-shaped plate B 4-21. The output end of the press wheel cylinder 4-22 is provided with a press wheel plate 4-23, and the press wheel plate 4-23 is arranged above the swing plate A 2-63;

[0065] The tensioning drive module further includes a rope clamping block A 4-24 installed in the middle of the support plate 4-11. Above the rope clamping block A 4-24, a rope clamping cylinder 4-25 is installed. The output end of the rope clamping cylinder 4-25 is provided with a rope clamping block B 4-26 that cooperates with the rope clamping block A 4-24 to clamp the rope. The rope clamping cylinder 4-25 is fixedly installed on a vertical mounting block 4-27. At the other end of the vertical mounting block 4-27, a rope pulling cylinder 4-28 is installed. A push-pull block 4-29 is installed on the piston rod of the rope pulling cylinder 4-28, and the push-pull block 4-29 is fixedly installed on the vertical mounting block 4-27;

[0066] The cutting module 4-3 includes a rope cutting cylinder 4-31 installed on the lower end face of the support plate 4-11. A connecting block 4-32 is installed on the piston rod of the rope cutting cylinder 4-31. An L-shaped plate 4-33 is fixedly installed on the connecting block 4-32. The horizontal plate of the L-shaped plate 4-33 is located above the support plate 4-11, and a pair of scissors 4-34 and a scissors cylinder for driving the scissors to move are fixedly installed thereon. The pair of scissors 4-34 is located on one side of the rope pulling cylinder 4-25;

[0067] Before the rope winding module starts winding the rope, there is a nylon rope between the rope pressing block and the rope threading block and the nylon rope is pressed tightly. When the rope winding ends and before the rope winding module returns to the initial position, the pressing wheel cylinder is activated. The piston rod of the pressing wheel cylinder moves downward, driving the pressing wheel plate to move downward. When the pressing wheel plate moves downward, it presses on one end of the rocker plate A. The rocker plate A rotates clockwise around the axis, which drives the connecting plate to move upward. The upward movement of the connecting plate drives the rocker plate B to rotate clockwise. Since the rope winding module rotates clockwise and the rocker plate B also rotates, while both are rotating, the gap between the rope pressing block and the rope threading block becomes larger and the nylon rope falls off. The piston rod of the pressing wheel cylinder continues to move downward, and the gap between the rope pressing block and the rope threading block becomes smaller, and the nylon rope between the rope threading assembly and the nylon bag is clamped again. When the rope winding module reaches the middle between the rope winding module and the knotting module, the rope cutting cylinder, the rope clamping cylinder, and the rope pulling cylinder are activated simultaneously. The rope cutting cylinder drives the scissors to the front of the nylon rope. The piston rod of the rope clamping cylinder moves downward, and the rope clamping block A6-13 and the rope clamping block B6-15 cooperate to clamp the nylon rope. At the same time, the piston rod of the stretching cylinder extends to drive the push-pull block to move backward. The push-pull block drives the rope clamping block A, the rope clamping block B, and the vertically installed block to move successively, tightening the nylon rope. When the rope pressing block and the rope threading block clamp the nylon rope between the rope threading assembly and the nylon bag again, the scissors cylinder is activated to cut the nylon rope. After the nylon rope is cut, the rope winding module returns to its original position under the action of the spring. The rope cutting cylinder drives the rope cutting assembly to return to its original position. The pressing wheel cylinder, the rope clamping cylinder, and the rope pulling cylinder drive the tensioning drive module to return to its original position.
