Two corresponding string threading holes are respectively opened at the upper ends of the left and right bag surfaces of the hand-held bag for threading a rope. Clamping heads are arranged at both ends of the rope. In this way, it is not only convenient for threading the rope, but also the clamping heads are stuck in the bag body after passing through the string threading holes, so that the rope will not break away from the bag body. The existing hand-held bag string threading machine adopts a centering adjustment method, where the position of the front and rear center lines remains unchanged, and the insert members and the extract members approach or move away from each other to adapt to hand-held bags of different specifications, and the adjustment is not fast enough. Content of the Utility Model

[0003] In view of the technical problems existing in the background art, the utility model aims to provide a string threading machine with an adjusting function, which adjusts the first hole insert member and the first hole extract member based on the second hole of the bag surface, and the adjustment is fast.

[0004] To solve the above technical problems, the utility model adopts the following technical solution: The string threading machine with an adjusting function includes a frame. A bag body conveying mechanism is arranged on the frame. The bag body conveying mechanism forms a bag conveying path. The bag body is vertically arranged on the bag conveying path. A string threading device is arranged on the bag conveying path. The string threading device includes an inserting mechanism and an extracting mechanism. The inserting mechanism includes a left inserting mechanism and a right inserting mechanism.

The first hole insert member and the second hole insert member rotate towards each other or rotate in opposite directions. The extracting mechanism includes a left extracting mechanism and a right extracting mechanism. Both the left extracting mechanism and the right extracting mechanism include extract members. The extract members move left and right and move up and down. The extract members include a first hole extract member and a second hole extract member. Among them, both the first hole insert member and the first hole extract member are movably adjusted back and forth on the frame. When adjusting, both the second hole insert member and the second hole extract member are stationary, and both the first hole insert member and the first hole extract member move forward or backward for adjustment.

[0005] In this solution, the second hole insert member and the second hole extract member are stationary, and the first hole insert member and the first hole extract member are adjusted back and forth based on the second hole of the bag surface. Only a part of the string threading device needs to be moved, and the adjustment is fast and stable, and the adjustment structure is optimized.

[0006] Preferably, a controller is connected to the first hole insert and the first hole extractor. During adjustment, the second hole insert and the second hole extractor remain stationary, and the controller controls the first hole insert and the first hole extractor to move forward or backward for adjustment.

[0007] In this solution, the controller adjusts the first hole insert and the first hole extractor according to the input hole distance signal, with accurate adjustment and high automation.

[0008] Preferably, the bag conveying mechanism includes a conveyor belt, and a bag clamping assembly for clamping the bag is installed on the conveyor belt. The bag clamping assembly includes a first bag clamping member and a second bag clamping member. The first bag clamping member is movably adjusted back and forth on the conveyor belt, and when adjusting, the first bag clamping member moves in the same direction as the first hole insert for adjustment.

[0009] In this solution, the bag clamping members are distributed front and back, with the bag surface facing both sides. The first bag clamping member moves in the same direction as the first hole insert with the second hole on the bag surface as the reference, ensuring the stability of the bag clamping assembly for clamping the bag.

[0010] Preferably, the conveyor belt is movably installed on the frame and can move up and down relative to the frame.

[0011] In this solution, the conveyor belt moves up and down relative to the frame to adapt to different bag heights, so that the heights of the front and rear hole positions are aligned.

[0012] Preferably, the bag conveying mechanism is equipped with a bag blanking mechanism, which is movably adjusted back and forth. The bag blanking mechanism includes a suction member and a workbench. The suction member is movably arranged left and right and can move up and down. The workbench includes a conveyor belt, and a pusher for moving back and forth is arranged above the conveyor belt. Side baffles are arranged on the workbench, and the suction member and an upper baffle are arranged on the discharge side of the conveyor belt.

[0013] In this solution, the bags on the conveyor belt are placed closely against the side baffles. The bag blanking mechanism moves back and forth to adapt to the change in the distance between the hole position and the side. The suction member moves to the right and approaches the discharge side of the conveyor belt to adsorb the bag, then moves to the left to drive the bag to break away from the limit of the upper baffle, and descends to transfer the bag to the bag conveying mechanism. The pusher and the conveyor belt cooperate to stably convey the bag.

[0014] Preferably, the first hole insert is horizontally rotatably arranged on a first turning seat, the second hole insert is horizontally rotatably arranged on a second turning seat, the first turning seat is movably adjusted back and forth on a push plate, the second turning seat is fixedly arranged on the push plate, and the push plate is movably arranged left and right on the frame.

[0015] In this solution, the push plate drives the first turning seat and the second turning seat to move left and right, with unified and stable actions.

[0016] Preferably, the first hole extractor is arranged to move left and right on the first moving seat, the second hole extractor is arranged to move left and right on the second moving seat, the second moving seat is connected with a lead screw, the first moving seat is arranged to move forward and backward and adjust on the lead screw, and the lead screw is arranged to move up and down.

[0017] In this solution, the lead screw drives the first moving seat and the second moving seat to move up and down uniformly, with unified and stable actions. The first moving seat moves forward and backward along the lead screw, and the adjustment is accurate.

[0018] Preferably, the first moving seat is arranged to move up and down on the first vertical slide rail, the first vertical slide rail is arranged to move forward and backward and adjust on the frame, the second moving seat is arranged to move up and down on the second vertical slide rail, and the second vertical slide rail is arranged on the frame.

[0019] In this solution, by moving the first vertical slide rail forward and backward to adjust its position on the frame, the position of the first moving seat in the front-back direction can be correspondingly adjusted, and the first vertical slide rail and the second vertical slide rail can play a guiding role in the up and down movement of the second moving seat.

[0020] Preferably, the rope threading device further includes a rope pulling member, a blunt end mechanism for the hand-held rope, and a cutting mechanism for the hand-held rope. The rope pulling member is arranged to move forward and backward, and the rope pulling member has a rope taking position, a rope pulling position, and a rope feeding position. The rope feeding position is located between the rope taking position and the rope pulling position. The rope taking position is fixed, and the rope pulling position and the rope feeding position are arranged to move forward and backward and adjust. When adjusting, the rope feeding position moves in the same direction as the first hole inserting member. When the rope pulling member is in the rope feeding position, the starting end of the hand-held rope clamped by the rope pulling member is handed over to the first hole inserting member for clamping. The blunt end mechanism for the hand-held rope is arranged to move forward and backward and adjust. When adjusting, the blunt end mechanism for the hand-held rope moves in the opposite direction to the rope pulling position. The cutting mechanism for the hand-held rope is located between the rope pulling member and the blunt end mechanism for the hand-held rope. The cutting mechanism for the hand-held rope includes a clamping member. When the rope pulling member is in the rope taking position, the starting end of the hand-held rope clamped by the clamping member is handed over to the rope pulling member for clamping. When the rope pulling member is in the rope pulling position, the clamping member clamps the hand-held rope.

[0021] In this solution, when the rope pulling member is in the rope pulling position, the clamping member clamps the hand-held rope to fix the length of the hand-held rope. Then the rope pulling member moves to the rope feeding position and hands over the starting end of the hand-held rope to the first hole inserting member. Adding the rope pulling position increases the length of the hand-held rope and compensates for the elongation of the hand-held rope due to tension, ensuring that the actual length is consistent with the required length.

[0022] Preferably, the cutting mechanism for the hand-held rope includes a cutting member for cutting the card head of the hand-held rope. When cutting, the second hole inserting member and the clamping member clamp the hand-held rope, and the cutting member cuts the hand-held rope between the two.

[0023] In this solution, before and after the cutting point, it is clamped by the clamping member and the second hole insert. When cutting, the tension of the carrying handle rope is sufficient and the cutting effect is good.

[0024] The beneficial effects of the present utility model are as follows: The first hole insert and the first hole extractor are moved and adjusted based on the second hole on the bag surface. The adjustment is fast and stable, and the adjustment structure is optimized; the pulling rope position of the pulling rope member is increased and adjusted to compensate for the elongation caused by the tightening of the carrying handle rope, and to adapt to the changes in the material and length of the carrying handle rope. Therefore, the present utility model has substantial features and progress compared with the prior art. Description of the Drawings

[0038] In this embodiment, the conveying direction of the bag body is from front to back. The conveyor belt and the pusher cooperate to supply the suction member. The side baffle aligns the side edges of the bags on the conveyor belt, and the upper baffle limits the bags about to be discharged to prevent the bags from tipping over. The suction member is specifically a suction nozzle installed on the moving seat. The suction nozzle adsorbs the bag body and delivers it to the bag clamping assembly. The bag clamping member is specifically a clamp that can be opened and closed, which is a mature technology. The bag surfaces of the bags on the bag feeding path face left and right. The bag clamping assembly clamps the bag body and successively undergoes punching (riveting) and stringing. In the stringing device, the bag opening member 10 is specifically a suction nozzle installed on the moving frame. The suction nozzle is slidably and positionedly connected to the moving frame. When stringing, the two bag opening members 10 move towards each other to adsorb the bag surface and move in the opposite direction to open the bag mouth.

Guide rails are also arranged on the frame 1 to guide the moving plate 25.

[0039] In other alternative embodiments, the bags on the workbench can align the hole positions before and after the change by adjusting the side baffle, so that there is no need to adjust the bag discharging mechanism. The bags on the workbench can be pre-punched, and are positioned by rods passing through the stringing holes. The rods can be clamped by opening and closing claws. The rods are clamped by multiple claws in a relay manner, and the corresponding claws are loosened when the bags pass by. The bag clamping member can also be immobile and adjustable as long as it can clamp the bag body.

[0040] Referring to the attached drawings, the first hole inserting member 4 and the first hole pulling-out member 7 are connected with a controller. When adjusting, the second hole inserting member 5 and the second hole pulling-out member 9 are both stationary, and the controller controls the first hole inserting member 4 and the first hole pulling-out member 7 to move forward or backward for adjustment.

[0041] In this embodiment, the controller can also be connected to the punching (riveting) device, the conveyor belt, the rope pulling member 19, and the blunt end mechanism 20 of the carrying rope. The connection between the controller and the corresponding control structure can be an electrical connection or a wireless signal connection, as long as signals can be transmitted. Parameters can be pre-recorded and the corresponding parameters can be selected according to the bag body specifications, or parameters can be manually input, such as the hole pitch, the bag height, and the rope length. When adjustment is required, the conveyor belt is adjusted to rise and fall according to the input bag height, the rope feeding positions of the first hole inserting member 4, the first hole pulling-out member 7, and the rope pulling member 19 are adjusted in the same direction according to the input hole pitch, and the rope pulling member 19 and the blunt end mechanism 20 of the carrying rope are adjusted in the opposite direction according to the input rope length.

[0042] Referring to the attached drawings, the rope threading device 3 further includes a rope pulling member 19, a blunt end mechanism 20 of the carrying rope, and a cutting mechanism 21 of the carrying rope. The rope pulling member 19 is arranged to move back and forth. The rope pulling member 19 has a rope taking position, a rope pulling position, and a rope feeding position. The rope feeding position is located between the rope taking position and the rope pulling position. The rope taking position is fixed. The rope pulling position and the rope feeding position are adjusted to move back and forth. When adjusting, the rope feeding position is adjusted to move in the same direction as the first hole inserting member 4. When the rope pulling member 19 is in the rope feeding position, the starting end of the carrying rope clamped by the rope pulling member 19 is clamped by the first hole inserting member 4. The blunt end mechanism 20 of the carrying rope is adjusted to move back and forth. When adjusting, the blunt end mechanism 20 of the carrying rope is adjusted to move in the opposite direction to the rope pulling position. The cutting mechanism 21 of the carrying rope is located between the rope pulling member 19 and the blunt end mechanism 20 of the carrying rope. The cutting mechanism 21 of the carrying rope includes a clamping member 26 and a cutting member for cutting the clamping head of the carrying rope. When the rope pulling member 19 is in the rope taking position, the starting end of the carrying rope clamped by the clamping member 26 is clamped by the rope pulling member 19. When the rope pulling member 19 is in the rope pulling position, the clamping member 26 clamps the carrying rope. When cutting, the second hole inserting member 5 and the clamping member 26 clamp the carrying rope, and the cutting member cuts the carrying rope between the two.

[0043] In this embodiment, the blunt-end mechanism 20 of the carrying cord wraps a plastic sheet around the carrying cord to form a clamping head. When the cord-pulling member 19 reaches the cord-taking position, it clamps the starting end of the carrying cord held by the clamping member 26, and the clamping member 26 releases the carrying cord to allow it to be stretched. The cord-pulling member 19 moves backward to reach the cord-pulling position, and the clamping member 26 clamps the carrying cord so that the length of the carrying cord between the cord-pulling member 19 and the clamping member 26 is determined. The cord-pulling member 19 moves forward to reach the cord-feeding position, and the first hole-inserting member 4 and the second hole-inserting member 5 rotate in opposite directions to the in-place position and clamp the carrying cord. The cutting member cuts the carrying cord between the second hole-inserting member 5 and the clamping member 26 to form a new starting end and a new ending end of the carrying cord. The second hole-inserting member 5 clamps the ending end of the carrying cord, and the clamping member 26 clamps the starting end of the carrying cord. The two side bag-opening members 10 move towards each other to suck the left and right bag surfaces, and move in the reverse direction to open the bag mouth. The first hole-inserting member 4 and the second hole-inserting member 5 rotate towards each other to align with the first hole and the second hole on the bag surface. The inserting members on both sides move towards each other to insert the clamping heads at both ends of the carrying cord into the cord-passing holes. Among them, the blunt-end mechanism 20 of the carrying cord and the carrying cord cutting mechanism 21 are mature technologies. When the material of the carrying cord changes, the cord-pulling position is adjusted forward and backward to adapt to the change in the elongation amount. When the length of the carrying cord changes, the blunt-end mechanism 20 of the carrying cord and the cord-pulling position are adjusted in the reverse direction to adapt to the change in the cord length and the elongation amount, so as to compensate for the starting end of the carrying cord.

[0044] In other alternative embodiments, in addition to the lead screw, a combination of a moving block and a synchronous belt can also be used for the movement adjustment.

[0045] The above is the preferred embodiment of the present invention. It should be noted that the protection scope of the present invention is not limited thereto. For those skilled in the art of this technology, without departing from the technical scope disclosed by the present invention under the premise of the same inventive concept, several improvements, refinements or equivalent replacements can also be made, which are also regarded as the protection scope of the present invention.
