Description

Technical Field

[0001] This utility model relates to the field of packaging box stringing technology, specifically a packaging gift box stringing device. Background Technology

[0002] Currently, in the production process of gift boxes, it is often necessary to attach carrying straps to the boxes for ease of carrying or to enhance the aesthetics of the packaging. Traditionally, the strap-threading process relies mainly on manual labor. Operators must manually thread the rope ends one by one through the holes on the side of the packaging box. This is not only inefficient, but also labor-intensive and prone to errors when processing large quantities of gift boxes, resulting in inaccurate rope placement or rope ends coming loose, thus affecting product quality. Utility Model Content

[0003] In view of the problems existing in the prior art, this utility model discloses a rope threading device for packaging gift boxes. The technical solution adopted includes a table, a conveyor belt, an intelligent controller, a support plate, an L-shaped bracket, and an electric push rod. These are all conventional mechanical parts or common tools. The device also includes a top U-shaped mounting rod, a mounting frame, a winding structure, an upper connecting rope, an I-shaped plate, a lower connecting rope, a sliding part, a T-shaped slider, mounting holes, a clamping plate, a vertical stabilizing shaft, and a clamping plate opening structure. The table is placed in front of the conveyor belt, which transfers the packaging boxes. The support plate is located below the conveyor belt, and the L-shaped bracket is fixed on the support plate. The electric push rod is mounted on the L-shaped bracket, and the electric push rod and the conveyor belt are connected by wiring. The system is controlled by an intelligent controller. The downward extension length of the electric push rod is related to the height of the through-hole on the side of the packaging box and is adjusted according to the actual situation. The conveyor belt operates intermittently via the intelligent controller, running for a period of time and then stopping for a period of time. This is to transfer individual packaging boxes one by one to the center below the electric push rod. The intermittent frequency is adjusted according to the actual specifications and hole positions of the packaging boxes. Relevant technicians can easily obtain this information through a limited number of experiments without any creative effort. The output end of the electric push rod is fixedly connected to the top U-shaped mounting rod, and the bottom of the top U-shaped mounting rod is fixedly connected to the mounting frame. The mounting frame is equipped with a winding structure, and a sliding part is provided on the side of the mounting frame. The T-shaped slider is placed through the sliding part. The T-shaped slider has a mounting hole on its outer end face. When the electric actuator is activated, the mounting hole corresponds to the through hole in the packaging box. The clamping plate and the vertical stabilizing shaft inside the mounting hole are movably fitted together. A clamping spring connects the upper and lower clamping plates to the upper and lower surfaces inside the mounting hole. Under the action of the clamping spring, the front ends of the upper and lower clamping plates are tightly fitted together. The clamping plates are opened by a clamping plate opening structure inside the mounting hole. The clamping plate opening structure is connected to the lower connecting rope. The other end of the lower connecting rope extends upwards from the L-shaped channel opened by the T-shaped slider and is fixedly connected to the I-shaped plate. An upper connecting rope is fixed at the center of the upper surface of the I-shaped plate. The upper end of the upper connecting rope is connected to the winding structure. When the winding structure operates, the upper connecting rope is pulled, thus... The clamping mechanism opens to grip the thread end initially positioned in the through-hole of the packaging box. The initial insertion of the thread end is done manually by the operator (with operators standing at both the front and back). The operator only needs to insert the thread end into the through-hole of the packaging box. The clamping mechanism resets under the rewinding mechanism, allowing the clamping head to grip the thread end. By manually moving the side of the packaging box, the rope will pass directly through the through-hole (common pull-out packaging boxes are usually in the form of paper bags). Alternatively, the electric push rod can be reset and pulled up to pull the rope in. This operation eliminates the need for manually threading each thread end individually; both ropes can be threaded simultaneously with both hands, effectively improving operational efficiency.

[0004] As a preferred embodiment of this utility model, the winding structure includes an upper convex plate, a stepper motor, and an upper rotating shaft. The upper convex plates are integrally formed on both the left and right ends of the mounting frame. The upper rotating shaft is rotatably mounted between the left and right upper convex plates. The stepper motor mounted on the right side of the right upper convex plate drives the upper rotating shaft. The stepper motor is fixed to the outer surface of the right upper convex plate via its own mounting flange (or a motor mount). The output shaft of the motor is aligned with the right end of the upper rotating shaft. Standard bearings are installed in the shaft holes of both upper convex plates. The journal of the upper rotating shaft is fitted into the inner ring of the bearing with a clearance fit. The output shaft of the stepper motor is connected to the upper rotating shaft via a coupling.

[0005] As a preferred technical solution of this utility model, the sliding part includes a window, a stabilizing shaft, a positioning blind hole and a through hole. The window extends through the front and rear sides of the mounting frame. The stabilizing shaft is fixed in the left and right directions of the window. The T-shaped slider is placed in the window and is movably fitted with the stabilizing shaft. Several positioning blind holes are distributed on the front and rear sides of the mounting frame. A through hole is opened on the vertical part of the T-shaped slider. A pin passes through the through hole and is inserted into the positioning blind hole to lock the position of the T-shaped slider.

[0006] As a preferred technical solution of this utility model, the upper connecting rope and the lower connecting rope are made of nylon material, the mounting hole has four vertical stabilizing shafts near the inner wall, and the movable parts are all at the horizontal part of the clamp.

[0007] As a preferred technical solution of this utility model, the clamping plate opening structure includes a trapezoidal plate, a movable shaft, a sleeve, an annular plate, and a spring. The inclined portion of the trapezoidal plate contacts the inclined portion of the clamping plate. The movable shaft is fixed at the center of the back of the trapezoidal plate. The sleeve is fixed to the inner wall of the mounting hole. The movable shaft is movably inserted into the sleeve. The annular plate is fixed to the outside of the movable shaft. The annular plate is connected to the inner wall of the mounting hole by a spring. The lower end of the lower connecting rope is fixedly connected to the protruding part of the outer edge of the annular plate.

[0008] The beneficial effects of this invention are as follows: By setting up a conveyor belt for automatic feeding, and with the electric actuator, clamping plate, and clamping plate opening structure working together to automatically clamp and pull the thread end, it replaces the traditional operation mode that relies entirely on manual rope threading. The operator only needs to initially place the rope end at the through hole of the packaging box, and the subsequent clamping and pulling actions are all completed automatically by the device, realizing semi-automatic operation. In particular, it supports simultaneous double rope threading by operators on both the front and back sides, which improves the rope threading efficiency several times compared to purely manual operation, effectively meeting the needs of mass production, significantly reducing the skill requirements of operators, reducing training costs and time, helping enterprises control labor costs, and maintaining a stable production rhythm.

[0016] As a preferred technical solution of this utility model, the sliding part includes a window 12, a stabilizing shaft 13, a positioning blind hole 15, and a through hole 16.

[0017] As a preferred technical solution of this utility model, the upper connecting rope 9 and the lower connecting rope 11 are made of nylon material, the mounting hole 17 has four vertical stabilizing shafts 19 near the inner wall, and the movable parts are all at the horizontal part of the clamping plate 18.

[0018] As a preferred technical solution of this utility model, the clamping plate opening structure includes a trapezoidal plate 20, a movable shaft 21, a sleeve, an annular plate 22, and a spring 23. The inclined portion of the trapezoidal plate 20 contacts the inclined portion of the clamping plate 18. The movable shaft 21 is fixed at the center of the back of the trapezoidal plate 20.

[0019] The working principle of this utility model is as follows: First, the device is adjusted according to the specifications of the packaging box to be threaded with ropes. The operator moves the T-shaped sliders on both sides of the front and rear sides through the sliding part, changing the distance between them so that the mounting holes on them are aligned with the through holes on the side of the packaging box, and locks them with pins. At the same time, the intelligent control program is set to control the intermittent running rhythm of the conveyor belt and adjust the downward extension stroke of the electric push rod to ensure that the mounting holes are accurately aligned with the through holes of the packaging box when it descends to the correct position; then the device is started. The conveyor belt runs intermittently under the control of the intelligent controller, and stops after transporting a packaging box to the predetermined working position directly below the electric push rod. At this time, the operators located on the front and rear sides of the packaging box manually insert the ends of the two lifting ropes into the through holes on the front and rear sides of the packaging box from the outside, so that the rope ends slightly extend into the through holes. After receiving the control signal, the electric push rod starts, pushing the top U-shaped mounting rod, the mounting frame and the entire clamping mechanism on it downward. When the mounting hole at the front end of the T-shaped slider reaches the position flush with the through hole of the packaging box, the electric push rod stops. Subsequently, the winding mechanism (driven by a stepper motor to the upper rotating shaft) actuates, tightening the upper connecting rope. The upper connecting rope pulls the I-beam plate, which in turn drives the lower connecting rope upwards. The lower connecting rope then pulls the annular plate in the clamping plate opening mechanism, overcoming the spring force to move backwards, pushing the movable shaft and the trapezoidal plate backwards within the sleeve. The inclined surface of the trapezoidal plate then presses against the inclined surfaces of the upper and lower clamping plates, overcoming the force of the tightening spring, causing the front ends (clamping ends) of the upper and lower clamping plates to open. At this point, the opened clamping plates are positioned precisely behind the rope end pre-placed by the operator. Next, the winding mechanism reverses and resets, releasing the upper and lower connecting ropes. Under the restoring force of the spring in the clamping plate opening mechanism, the trapezoidal plate moves forward, and the upper and lower clamping plates quickly close under the action of the tightening spring, firmly clamping the rope end between them. The electric actuator retracts, driving the entire clamping mechanism upwards. Because the clamping plate tightly holds the rope end, as the clamping mechanism rises, the rope end is pulled out of the through hole, allowing the entire rope to be smoothly threaded through the through hole of the packaging box, completing the rope threading action. Once the clamping mechanism reaches its initial height, the operator can easily remove the pulled-out rope end from the clamping plate. Simultaneously, the conveyor belt starts, removing the threaded packaging box and transporting the next packaging box to be processed to the work position, thus initiating the next work cycle.
