Referring to the accompanying drawings, the conveying of the hand rope of the present invention is arranged parallel to the conveying of the bag body, and the threading direction is perpendicular to the conveying direction of the hand rope. After grasping the clamping head, the insertion devices 56 and 57 need to turn the clamping head so that the clamping head is aligned with the threading direction, and then insert the clamping head into the threading hole of the bag body.

[0023] This handbag string threading mechanism includes a frame, a bag opening device 58, insertion devices 56 and 57 for grabbing the cut handbag string and inserting the clamp into the string threading hole, and extraction devices 59 and 65 for allowing the inserted clamp to enter the bag body; the insertion device includes a left insertion device 56 and a right insertion device 57, and the extraction device includes a left extraction device 59 and a right extraction device 65. A bag channel 60 is provided on the frame. In this embodiment, the bag channel 60 is vertically arranged, and the left insertion device and the right insertion device are respectively arranged on both sides of the bag channel. In order to improve the stability of the insertion device when threading the string, guide plates are provided on both sides of the bag channel, and the clamping parts of the insertion device move left and right along the guide plates. The left extraction device and the right extraction device are arranged on the inner side of the bag channel. A bag positioning plate 66 is also provided on the inner side of the bag channel. The bag positioning plate is connected to a power source that drives it to rise and fall. In this embodiment, the power source is a cylinder.

[0024] The bag opening device 58 includes a suction seat 67, a suction nozzle 61 installed on the suction seat and a power source 62 that drives the suction seat to move forward and backward. The suction nozzle is connected to an air pump, and the power source is a cylinder. The insertion device includes rope-taking components 53 and 55 and a transmission component 54 that drives the rope-taking components to rotate horizontally and move left and right. The rope-taking components are clamping parts that clamp the hand rope. The clamping parts in this embodiment use pneumatic clamping fingers of the prior art. The clamping parts have two, namely, a front clamping part 53 and a rear clamping part 54, which are used to clamp the clamps at both ends of the hand rope. The front clamping part 53 and the rear clamping part are both 55 connected to the transmission component 54, and the transmission component 54 drives the front clamping part and the rear clamping part to rotate toward or in the opposite direction. The transmission component 54 includes a connecting rod assembly and a power source 50. The power source can be a cylinder, a mechanical cam, a hydraulic cylinder, etc. The present invention uses a cylinder, so The cylinder 50 is installed on the frame, and the connecting rod assembly has two groups, namely the front connecting rod assembly and the rear connecting rod assembly. The cylinder 50 is connected to the front clamping member 53 through the front connecting rod assembly, and the cylinder 50 is connected to the rear clamping member 55 through the rear connecting rod assembly, and the front and rear clamping members are driven by one cylinder to move synchronously; the front connecting rod assembly and the rear connecting rod assembly both include a connecting rod seat 45, a connecting rod 1 52 and a connecting rod 2 51, one end of the connecting rod 1 52 is hinged to the connecting rod seat 45, and the hinge is A, the clamping member is installed at the other end of the connecting rod 1 52, one end of the connecting rod 2 51 is hinged to the connecting rod 1 52, and the other end of the connecting rod 2 51 is hinged to the output shaft 49 of the cylinder, and the output shaft is the air The piston rod of the cylinder, the connecting rod seat 45 is provided with a through hole 46 for the piston rod to pass through, and the piston rod 49 is equipped with a push block 48 for adjusting the rotation angle of the clamping member. The push block 48 is arranged on the piston rod 49 between the cylinder 50 and the connecting rod seat 45, and the outer diameter of the push block 48 is larger than the diameter of the through hole 46. When the push block 48 is close to the connecting rod seat 45, that is, the stroke from the push block to the connecting rod seat is short, the stroke of the horizontal rotation of the clamping member driven by the cylinder 50 becomes shorter, then the angle of rotation of the clamping member is small, conversely, when the push block 48 is close to the cylinder 50, the angle of rotation of the clamping member is large, and the user can adjust the position of the push block 48 according to needs. The angle of rotation of the clamping member in this embodiment is 90 degrees, the push block 48 and the piston rod 49 can be connected by threads, so that the adjustment is fast and convenient; the frame is also provided with a limit block for controlling the reset position of the connecting rod 1 and a limit plate 47 for controlling the reset position of the connecting rod seat. When the clamping part is in the cutting working condition, it is necessary to ensure that the position of the clamping part and the hand rope are in the same straight line. To ensure that the clamping part is in the specified position, when the cylinder 50 drives the connecting rod seat and the clamping part to reset, the connecting rod seat moves first, and when the connecting rod seat contacts the limit plate, the connecting rod seat stops moving, and the cylinder 50 continues to drive the clamping part to reset, and the connecting rod 1 contacts the limit block. The limit block restricts the connecting rod 1 from continuing to swing, and the clamping part no longer rotates. At this time, the clamping part is in the specified position.

[0025] The left extraction device 59 and the right extraction device 65 each include a clamping member, a moving part 64 that drives the clamping member to move left and right, and a lifting part 63 that drives the clamping member to move up and down. In this embodiment, the clamping member also uses the existing pneumatic clamping fingers; the lifting part and the moving part are both cylinders, which respectively drive the clamping member to move up and down and move left and right. During the rope threading operation, the bag opening device 58 separates the bag surface left and right, and the clamping members of the insertion devices 56 and 57 clamp the clip of the cut hand rope. The clamping members 53 and 55 rotate to align the clip with the rope threading hole on the bag body. The transmission part 54 drives the clamping member to move toward the rope threading hole so that the clip is inserted into the rope threading hole. The clamping members of the extraction devices 59 and 65 clamp the inserted clip and pull the clip into the bag body.

[0026] When the present invention is in operation, the clamping members 53 and 55 are used to take the rope at the cutting station. The front clamping member 53 is opened to clamp the clamping head on the hand rope, and the rear clamping member 55 is opened to clamp the starting end of the hand rope, that is, the clamping head that has been cut is clamped, and the cutting device performs the cutting work. The clamping member has a certain distance from the front end of the clamping head. When the bag body is threaded with rope, the clamping head is inserted into the rope threading hole; at this time, the bag body is vertically arranged in the bag body channel 60, and the suction nozzle 61 sucks air to adsorb the left and right bag surfaces of the bag body, and the cylinder 62 drives the suction nozzles 61 on both sides of the bag body to move in the opposite direction to open the bag body, so that the bag mouth of the bag body is opened, and then the bag body is opened. The bag body positioning plate 66 moves down, and the positioning plate cooperates with the suction nozzle to clamp and fix the bag surface, which is convenient for the subsequent rope threading work; the clamping members 53 and 55 turn the clamped card head to align the card head with the rope threading hole. After the cutting is completed, the pneumatic piston rod 49 is extended, and the front end of the piston rod passes through the through hole 46 on the connecting rod seat. At this time, the connecting rod seat 45 does not move, and the piston rod drives the connecting rod 2 51 to swing outward, and forces the connecting rod 1 52 to swing toward the rope threading station with A as the center, that is, the two clamping members 53 and 55 rotate toward each other until the push block 48 on the piston rod contacts the connecting rod seat 45. At this time, the card head clamped by the clamping member is facing the bag body. The through hole of the bag body is formed, and the piston rod 49 continues to extend, pushing the connecting rod seat 45 to move toward the bag body, so that the clamping head is inserted into the through hole on the bag body; then the clamping piece in the open state moves down to the clamping head position, the left and right clamping plates are closed, and the clamping head is clamped, and the moving component drives the clamping pieces to move toward each other, so that the clamping head inserted into the rope threading hole enters the bag body, and then the clamping heads of the extraction devices 59 and 65 in the open state move down to the clamping head position to clamp the clamping head, and the moving component 64 drives the clamping heads to move toward each other, so that the clamping head inserted into the rope threading hole enters the bag body, so that the clamping head completes the rope threading, and then the clamping head of the extraction device is reset, and the fixed The positioning plate moves upward, the suction cup stops sucking air, and after the insertion is completed, the rope-taking component is also reset, that is, the piston rod 49 retracts, driving the connecting rod seat 45 to reset until the connecting rod seat contacts the limit plate 47 on the frame, and the piston rod 49 continues to retract, and the connecting rod seat 45 does not move. The inner side of the connecting rod 2 51 swings, forcing the connecting rod 1 52 to swing toward the cutting station with A as the center, so that the two clamping parts rotate in the opposite direction until the connecting rod 1 contacts the limit block, and the clamping parts return to the cutting station. The front clamping part 53 and the rear clamping part 55 respectively clamp the two ends of the hand rope, and this is repeated, and the bag body is automatically perforated.
