Description

Technical Field

[0001] This application relates to the field of cigarette pack unpacking pull cord technology, and in particular to an unpacking pull cord device. Background Technology

[0002] Cigarette pull tabs are crucial components for opening cigarette packaging. They not only facilitate easy opening but also play a vital role in anti-counterfeiting, aesthetics, and brand promotion. With the diversified development of the domestic cigarette industry, the demand for differentiated pull tabs from different brands and specifications of cigarette products continues to increase. In addition to conventional transparent BOPP pull tabs, the application of various functional pull tabs, such as laser pull tabs with holographic anti-counterfeiting patterns, easy-tear pull tabs, and color-printed pull tabs, is increasing year by year. These pull tabs exhibit significant differences in pull tab width, substrate thickness, cigarette specifications, and unwinding tension requirements, placing higher demands on the adaptability, adjustment flexibility, and unwinding stability of production equipment.

[0003] Cigarette pack pull cords (also known as gold pull cords or unpacking pull cords) are a core auxiliary material for cigarette outer packaging. The core production processes are wide-width mother film slitting and finished cigarette roll winding. Currently, most unpacking pull cord unwinding equipment in the industry is a single-station fixed structure design. The installation position of the guide roller group and the cord path are fixed, only adaptable to a single specification of pull cord roll. When producing pull cord products of different specifications, frequent equipment changes and readjustment of cord path and tension parameters are required, with a single changeover and adjustment time exceeding 30 minutes, severely impacting production efficiency and making it difficult to meet the current cigarette industry's production needs of small batches, multiple batches, and fast delivery. Traditional pull cord production equipment suffers from the following core pain points: existing pull cord production equipment cannot adapt to different types of rolls, resulting in different types of rolls needing to be placed on designated unpacking pull cord equipment. Therefore, a new unpacking pull cord equipment is proposed to solve the above problems. Summary of the Invention

[0004] The purpose of this application is to propose a decapsulation and drawing device to solve the problem that traditional drawing production equipment cannot adapt to different types of drums, resulting in different types of drums needing to be placed on a specific decapsulation and drawing device.

[0005] To achieve this objective, the following technical solution is adopted in this application: A packaging unpacking and cable pulling device includes at least one packaging unpacking and cable pulling mechanism. The packaging unpacking and cable pulling mechanism includes a mounting plate, an unwinding roller, a linear module, a vertical plate, a first auxiliary roller, a second auxiliary roller, and a third auxiliary roller. The unwinding roller is rotatably connected to the mounting plate, and the axis of the unwinding roller is perpendicular to the mounting plate. The linear module is disposed on the mounting plate, and the movement direction of the drive slider of the linear module is perpendicular to the mounting plate. A base is provided on the drive slider of the linear module, and the vertical plate is disposed on the base. The first auxiliary roller is detachably and rotatably connected to the vertical plate. The second auxiliary roller is rotatably connected to the base, and the axis of the second auxiliary roller is perpendicular to the axis of the first auxiliary roller. The third auxiliary roller is rotatably connected to the linear module, and the axis of the third auxiliary roller is parallel to the axis of the second auxiliary roller.

[0006] As a preferred technical solution of this application, the unpacking and pulling mechanism further includes a feeding and correction unit, which is disposed on the linear module to adjust the tension of the unpacking and pulling wire wound on the unwinding roller.

[0007] As a preferred technical solution of this application, the feeding correction unit includes two mounting seats, a damping shaft, a connecting rod, and a tension adjusting roller. The two mounting seats are spaced apart on the base. The two ends of the damping shaft are rotatably connected to the mounting seats respectively. One end of the connecting rod is fixedly sleeved on the damping shaft, and the other end of the connecting rod is rotatably connected to the tension adjusting roller.

[0008] As a preferred technical solution of this application, the swing angle range of the connecting rod around the damping shaft is ±15°, and the rotation damping force of the damping shaft can be preset and adjusted according to the material and thickness of the unpacking pull cable.

[0009] As a preferred embodiment of this application, the system further includes a fourth auxiliary roller and a fifth auxiliary roller, both of which are rotatably connected to the mounting plate. The axis of the fourth auxiliary roller is perpendicular to the axis of the third auxiliary roller, and the axis of the fifth auxiliary roller is parallel to the axis of the fourth auxiliary roller. The fifth auxiliary roller is located on the side of the fourth auxiliary roller away from the unwinding roller.

[0010] As a preferred technical solution of this application, the number of the unpacking pull-cord mechanism is multiple, and the multiple unpacking pull-cord mechanisms are arranged linearly. Alternatively, there may be multiple unpacking and pulling mechanisms arranged horizontally and stacked vertically to form a matrix. The distance between the fifth auxiliary roller on the lower mounting plate and the unwinding roller is greater than the distance between the fifth auxiliary roller on the adjacent upper mounting plate and the unwinding roller.

[0011] As a preferred technical solution of this application, the vertical plate is provided with a plurality of mounting holes, and the first auxiliary roller is mounted in the corresponding mounting holes through a bearing seat.

[0012] As a preferred technical solution of this application, the roller bodies of the first auxiliary roller, the second auxiliary roller, and the third auxiliary roller are all mirror-polished surfaces, and both ends of the roller bodies of the first auxiliary roller, the second auxiliary roller, and the third auxiliary roller are provided with anti-detachment edges with rounded transitions.

[0013] Compared to existing technologies, the beneficial effects of this application are: 1. Wide applicability and strong versatility, significantly reducing equipment investment costs. This application utilizes the adjustable design of the linear module, combined with multiple sets of vertically / parallel auxiliary roller reversing guide structures, and multi-position mounting holes on the vertical plate to achieve flexible adjustment of the installation height of the first auxiliary roller. It can fully adapt to unpacking and drawing reels with different inner diameters, outer diameters, widths, and unwinding tension requirements, breaking the limitation of traditional equipment that can only adapt to specific types of reels. It eliminates the need for dedicated production equipment for different specifications of reels, greatly expanding the applicable scenarios of the equipment and significantly reducing equipment investment costs on the production side.

[0014] 2. Strong unwinding stability and high correction accuracy effectively improve product yield. This application utilizes a feeding correction unit with a damped rotating shaft, combined with a synchronous displacement correction design of the linear module. On one hand, the adaptive oscillation of the tension adjustment roller compensates for tension fluctuations during the unwinding process, ensuring constant unwinding tension throughout and effectively preventing defects such as loosening, stretching deformation, and breakage of the wire. On the other hand, the linear module drives the synchronous displacement of the guide and correction structure, achieving precise real-time correction of the wire conveying position and eliminating problems such as wire deviation, edge flipping, and wrinkling. Simultaneously, the core guide roller's axis remains parallel to the linear module's slider movement direction, ensuring that the wire support surface remains flat during correction adjustment, further improving conveying stability, comprehensively guaranteeing the surface integrity and product consistency of the unpacked wire, and increasing the product yield.

[0015] 3. The modular design offers high flexibility, enabling simultaneous operation at multiple workstations and providing strong adaptability to production efficiency and site conditions. This application adopts a modular unpacking and pulling mechanism design. By adding a fourth and fifth auxiliary roller with a secondary reversing structure, and with adjacent mounting plates arranged vertically or horizontally, the number of workstations can be flexibly increased or decreased according to production capacity requirements without modifying the main body of the equipment. At the same time, the staggered fifth auxiliary roller ensures that the pulling wires output by multiple mechanisms do not interfere with or cross each other during the conveying process, enabling simultaneous and synchronous unwinding of multiple sets of different types of drums, significantly improving the production efficiency of the equipment. It can also flexibly adapt to production sites of different areas and layouts, significantly improving the utilization rate of site space. Attached Figure Description

[0023] Figure 1 and Figure 2This application provides a packaging unpacking and pulling device, including at least one packaging unpacking and pulling mechanism 1. The packaging unpacking and pulling mechanism 1 includes a mounting plate 11, an unwinding roller 12, a linear module 13, a vertical plate 15, a first auxiliary roller 16, a second auxiliary roller 17, and a third auxiliary roller 18. The unwinding roller 12 is rotatably connected to the mounting plate 11, and the axis of the unwinding roller 12 is perpendicular to the mounting plate 11. The linear module 13 is disposed on the mounting plate 11, and the direction of movement of the drive slider of the linear module 13 is perpendicular to the mounting plate 11. A base 14 is provided on the drive slider of the linear module 13, and the vertical plate 15 is disposed on the base 14. The first auxiliary roller 16 is detachably and rotatably connected to the vertical plate 15. The second auxiliary roller 17 is rotatably connected to the base 14, and the axis of the second auxiliary roller 17 is perpendicular to the axis of the first auxiliary roller 16. The third auxiliary roller 18 is rotatably connected to the linear module 13, and the axis of the third auxiliary roller 18 is parallel to the axis of the second auxiliary roller 17.

[0024] Mounting plate 11 serves as the supporting base for the entire unpacking and pulling mechanism 1, providing a stable mounting reference for unwinding roller 12 and linear module 13, ensuring the coaxiality and parallelism of each moving part; unwinding roller 12 provides a supporting carrier for the rotation and unwinding of the drum; first auxiliary roller 16, second auxiliary roller 17, and third auxiliary roller 18 form a three-level guiding and reversing system, which achieves smooth reversal of the pulling wire conveying direction through a pair of perpendicular / parallel arrangement, while providing multi-point support for the pulling wire to avoid sagging and shaking problems during long-distance conveying.

[0025] In this embodiment, according to the type and quantity of the unpacking pull wire reels to be produced, a corresponding number of unpacking pull wire mechanisms 1 are configured. Each unpacking pull wire reel is coaxially mounted on the corresponding unwinding roller 12 to complete the material preparation before unwinding. After the unpacking pull wire is led out from the unwinding roller 12, it passes through the first auxiliary roller 16, the second auxiliary roller 17, and the third auxiliary roller 18 in sequence to complete the wire feeding and reversing conveying. Among them, the first auxiliary roller 16 provides initial support and guidance for the pull wire led out from the unwinding roller 12. The second auxiliary roller 17, which is perpendicular to the first auxiliary roller 16, completes the 90° reversal of the wire feeding direction. Then, the third auxiliary roller 18, which is parallel to the second auxiliary roller 17, stably conveys the wire after reversing, ensuring the flatness of the wire during the wire feeding process and avoiding wrinkles and edge flipping problems. During the unwinding and conveying process, when the wire deviates laterally or needs to be adapted to the conveying position requirements of different rolls, the linear module 13 drives the base 14, vertical plate 15, and corresponding first auxiliary roller 16, second auxiliary roller 17, and other guide components to move synchronously along the axial direction of the linear module 13 to adjust the position. This achieves precise adjustment and real-time correction of the wire conveying position, ensuring the accuracy of the wire conveying position. It can adapt to unpacked wire rolls with different inner diameters, widths, and unwinding tension requirements, eliminating the need for dedicated equipment for different types of rolls and greatly improving the versatility and adaptability of the equipment.

[0026] Optionally, the unpacking and pulling wire mechanism 1 further includes a feeding and correction unit, which is disposed on the linear module 13 to adjust the tension of the unpacking and pulling wire wound on the unwinding roller 12. Specifically, the feeding and correction unit includes two mounting seats 1111, a damping shaft 1112, a connecting rod 1113, and a tension adjusting roller 1114. The two mounting seats 1111 are spaced apart on the base 14. The two ends of the damping shaft 1112 are rotatably connected to the mounting seats 1111 respectively. One end of the connecting rod 1113 is fixedly sleeved on the damping shaft 1112, and the other end of the connecting rod 1113 is rotatably connected to the tension adjusting roller 1114.

[0027] Because existing technologies lack integrated real-time correction and adaptive tensioning structures, traditional equipment is prone to problems such as wire deviation and excessive tension fluctuations during high-speed unwinding. This not only leads to quality defects such as wire stretching and deformation, misalignment of anti-counterfeiting patterns, and edge fraying, but also frequently causes tape breakage and downtime, significantly increasing product losses and production and maintenance costs. To address this issue, this application adds a feeding correction unit to perform real-time correction and tension adjustment of the wire's conveying position. After the unsealed wire is led out from the unwinding roller 12, it first passes through the tension adjusting roller 1114 and then is conveyed to the first auxiliary roller 16. The tension adjusting roller 1114 is linked to the damping shaft 1112 through the connecting rod 1113. The damping shaft 1112 provides constant rotational damping, adaptively adjusting the tension of the wire to compensate for tension fluctuations during unwinding and ensure constant unwinding tension. When the tension fluctuates during the unwinding process, the tension adjusting roller 1114 can drive the connecting rod 1113 to swing adaptively around the damping shaft 1112.

[0028] The axial directions of the unwinding roller 12, tension adjusting roller 1114, first auxiliary roller 16, fourth auxiliary roller 19, and fifth auxiliary roller 110 are parallel to the sliding motion direction of the linear module 13. This ensures that the axial direction of each roller remains consistent with the adjustment direction during position correction adjustment of the linear module 13, guaranteeing that the support surface of the tensioned wire remains flat throughout the correction process. This prevents wire deviation and detachment from the rollers, improving the accuracy and stability of the correction adjustment.

[0029] Optionally, the swing angle range of the connecting rod 1113 around the damping shaft 1112 is ±15°, and the rotation damping force of the damping shaft 1112 can be preset and adjusted according to the material and thickness of the unpacking pull cable.

[0030] The swing angle range of the connecting rod 1113 around the damping shaft 1112 is ±15°. This swing range can completely cover the tension variation range caused by changes in the outer diameter of the drum and fluctuations in the unwinding speed during the unwinding process, eliminating the need for real-time manual adjustment of the tension and significantly reducing the manual operation intensity of the equipment. The change in swing amplitude compensates for the tension fluctuation of the pull wire in real time, ensuring that the tension of the pull wire remains constant during the unwinding process and avoiding problems such as loose pull wire, stretching deformation, or breakage. At the same time, the damping force of the damping shaft 1112 can be preset and adjusted according to different drum materials and different thicknesses of unpacked pull wires, further adapting to the unwinding requirements of different types of drums and ensuring that the tension fluctuation throughout the unwinding process does not exceed ±5%, which is far superior to the ±15% tension fluctuation range of traditional equipment.

[0031] Optionally, such as Figure 2 As shown, it also includes a fourth auxiliary roller 19 and a fifth auxiliary roller 110, both of which are rotatably connected to the mounting plate 11. The fourth auxiliary roller 19 is perpendicular to the third auxiliary roller 18, and the fifth auxiliary roller 110 is parallel to the fourth auxiliary roller 19. The fifth auxiliary roller 110 is located on the side of the fourth auxiliary roller 19 away from the unwinding roller 12.

[0032] After the unpacked wire is led out from the unwinding roller 12, it passes through the first auxiliary roller 16, the second auxiliary roller 17, and the third auxiliary roller 18 in sequence to complete the wire feeding and reversal. Then, it passes through the fourth auxiliary roller 19 and the fifth auxiliary roller 110 to complete the second reversal and final output guidance. Through the perpendicular setting of the fourth auxiliary roller 19 and the third auxiliary roller 18, the wire feeding direction is reversed by 90° again, so that the final output direction of the wire is parallel to the unwinding direction of the unwinding roller 12.

[0033] Optionally, there may be multiple unpacking pull-cord mechanisms 1, which are arranged linearly. The mounting plates 11 of adjacent unpacking pull-cord mechanisms 1 may be arranged linearly along the vertical or horizontal direction.

[0034] Optionally, there may be multiple unpacking pull mechanisms 1, which are arranged horizontally and stacked vertically to form a matrix. The mounting plates 11 of adjacent unpacking pull mechanisms 1 are arranged in a matrix of multiple rows and columns in both the vertical and horizontal directions. The distance between the fifth auxiliary roller 110 on the lower mounting plate 11 and the unwinding roller 12 is greater than the distance between the fifth auxiliary roller 110 on the adjacent upper mounting plate 11 and the unwinding roller 12.

[0035] In practical applications, linear or matrix layout methods can be selected for flexible assembly and arrangement based on the on-site production space and the number of workstations required. When a large number of workstations are required, a matrix layout method can be adopted. The distance between the fifth auxiliary roller 110 on the lower mounting plate 11 and the unwinding roller 12 is greater than the distance between the fifth auxiliary roller 110 on the adjacent upper mounting plate 11 and the unwinding roller 12. This ensures that the final output direction of the multiple unpacking and pulling mechanisms 1 arranged in the upper and lower layers is parallel to and staggered with the unwinding direction of the unwinding roller 12, without interfering with or crossing each other. This allows multiple unpacking and pulling mechanisms 1 to operate simultaneously, and can simultaneously adapt to the synchronous production of various types of rolls, further improving the production efficiency and site adaptability of the equipment, and reducing the investment cost of production equipment. The horizontal misalignment distance of the fifth auxiliary rollers 110 of adjacent upper and lower layers can be set to 50mm-200mm. This distance can be adapted and adjusted according to the width of the unpacked wire and the conveying speed to ensure that even under high-speed unwinding conditions, the wires output from the upper and lower layers will not entangle or interfere with each other. The maximum unwinding speed of the equipment can reach 200m / min, which is suitable for high-speed large-scale production needs.

[0036] Optionally, the vertical plate 15 has multiple mounting holes 112, and the first auxiliary roller 16 is mounted in the corresponding mounting hole 112 through a bearing seat.

[0037] According to the outer diameter of the drum and the required cable routing height, the first auxiliary roller 16 can be fixedly installed in the mounting hole 112 at the corresponding height through the bearing seat, so that the installation height of the first auxiliary roller 16 can be flexibly adjusted to adapt to drums with different outer diameter specifications, ensuring that the cable routing angle after the cable is drawn out is always in the optimal range, avoiding friction and scratching between the cable and the edge of the drum, and protecting the surface integrity of the unpacked cable.

[0038] Optionally, the roller surfaces of the first auxiliary roller 16, the second auxiliary roller 17, and the third auxiliary roller 18 are all mirror-polished, and both ends of the roller bodies of the first auxiliary roller 16, the second auxiliary roller 17, and the third auxiliary roller 18 are provided with arc-transition anti-detachment guard edges.

[0039] This design effectively prevents the pull cord from coming off the edge of the roller during the conveying process, while also avoiding scratches on the edge of the pull cord by the sharp corners of the roller end, ensuring the neatness of the edges of the pull cord during unpacking, avoiding burr defects, and meeting the high requirements of cigarette packaging for the appearance of the pull cord.

[0040] In summary, this application achieves comprehensive compatibility with unpacking and pulling reels of different inner diameters, widths, materials, and tension requirements through the adjustable design of the linear module, the reversing and guiding structure of multiple auxiliary rollers, the adaptively adjustable feeding and correction unit, and the flexibly arranged multiple unpacking and pulling mechanisms. This solves the pain point of traditional equipment being unable to adapt to different types of reels and requiring dedicated equipment, significantly improving the equipment's versatility, production efficiency, and site adaptability, while reducing the investment cost of production equipment.
