Description

Technical Field

[0001] This utility model belongs to the field of cigarette manufacturing, specifically relating to a lifting-type heat-sealing device for transparent paper of cigarette cartons. Background Technology

[0002] In modern cigarette packaging production, carton linerboard is an indispensable auxiliary material for rigid packing machines (such as GDX1 and GDX2). Its main function is to wrap the folded cigarette cartons and seal them through heat sealing, thereby achieving the goals of moisture prevention, aroma preservation, and improved appearance and brand image. On automated packaging lines, after complex folding, the carton linerboard is finally heat-sealed by a dedicated soldering iron on the machine's longitudinal seam and both sides. However, automated production lines inevitably produce a certain percentage of defective or faulty products during high-speed operation. For example, minor defects in the carton cardboard, misalignment of the linerboard feed, or momentary equipment malfunctions can all lead to some cartons failing to be successfully wrapped. Each shift produces a certain number of unfinished cartons; discarding them directly would waste auxiliary materials and increase production costs. Therefore, cigarette factories usually collect these cartons and have operators manually salvage them: first, the linerboard is folded manually, then the seams are glued together using a heat sealing tool to bring them to quality standards before they are reintroduced into production or used for other purposes.

[0003] Currently, this manual remedial operation mainly relies on operators using ordinary soldering irons. However, this method has significant safety hazards and operational inconveniences. The constantly exposed high-temperature soldering iron tip easily causes burns, and the unstable operating posture makes it difficult to ensure uniform heat sealing pressure, resulting in inconsistent sealing quality. In addition, the lack of dedicated placement devices and management measures leads to a cluttered workbench, low operating efficiency, high energy consumption, and a reduced lifespan for the soldering iron.

[0004] This application is submitted to address the aforementioned issues. Utility Model Content

[0005] To address the problems of significant safety hazards, inconvenience, inconsistent heat-sealing quality, and cluttered workbenches associated with manual heat-sealing of translucent paper strips in existing technologies, this invention aims to provide a lifting-type heat-sealing device for translucent paper strips. This device utilizes a cam-driven lifting mechanism operated by a handle to switch the soldering iron between a working position and a retractable position. When not in use, the high-temperature soldering iron tip is retracted into the machine casing, effectively reducing the risk of burns to operators and improving safety. Simultaneously, a guide support mechanism ensures smooth lifting and pressing of the soldering iron, guaranteeing uniform heat-sealing pressure. Combined with a temperature controller to monitor the soldering iron temperature, stable and reliable sealing quality is achieved. By adding a protective cover, a cooling fan, and optimizing the ventilation structure, equipment safety and heat dissipation efficiency are improved, resulting in a cleaner and more organized operating environment, improved work site management, and the creation of a safe, efficient, and controllable dedicated heat-sealing workstation.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A lifting-type heat-sealing device for transparent paper in a strip box is provided, comprising:

[0008] Casing 1;

[0009] Soldering iron 2 is disposed inside the housing 1 and electrically connected to the power module inside the housing 1;

[0010] The lifting mechanism includes a rotating shaft 3 rotatably supported in the housing 1 and a cam 4 coaxially fixedly sleeved on the rotating shaft 3, with the lower surface of the soldering iron 2 abutting against the outer contour of the cam 4.

[0011] The operating handle 5 is located outside the housing 1 and connected to one end of the rotating shaft 3, and is used to drive the rotating shaft 3 to rotate.

[0012] Operating the control handle 5 can drive the cam 4 to rotate, thereby driving the soldering iron 2 to rise and fall vertically relative to the housing 1, switching it between the working position and the storage position.

[0013] Preferably, a guide support mechanism is provided between the soldering iron 2 and the housing 1. The guide support mechanism includes at least two vertically arranged guide rods 6. The upper end of each guide rod 6 is fixedly connected to the soldering iron 2, and the lower end is slidably engaged with a sliding bearing 7 fixed in the housing 1.

[0014] Preferably, there are four guide rods 6, which are respectively located at the four corners of the soldering iron 2.

[0015] Preferably, the housing 1 is provided with a cooling fan facing the soldering iron 2, and the side wall of the housing 1 is provided with a ventilation opening 9 corresponding to the cooling fan.

[0016] Preferably, the vent 9 is a louvered vent with a dustproof structure.

[0017] Preferably, a temperature controller 10 for monitoring and / or controlling the temperature of the soldering iron 2 is installed on the housing 1.

[0018] Preferably, the rotating shaft 3 is supported by a bearing on a support 13 fixedly disposed inside the housing 1.

[0019] Preferably, the device further includes a protective cover 11 that can be opened and closed and is disposed above the housing 1, and the protective cover 11 has a plurality of heat dissipation holes 12 distributed thereon.

[0020] Preferably, the heat dissipation holes 12 are honeycomb-shaped holes.

[0021] Preferably, the outer contour of the cam 4 is elliptical or eccentrically circular, used to drive the soldering iron 2 to reciprocate up and down in the vertical direction.

[0022] The advantages of this utility model over the prior art are as follows:

[0023] 1. This utility model achieves the "raise when in use, store when not in use" capability of the soldering iron by combining a cam lifting mechanism with a protective cover. The high-temperature soldering iron tip is safely isolated inside the protective cover when not in use, fundamentally avoiding the risk of burns to the operator and greatly improving operational safety.

[0024] 2. With this invention, the operator can easily control the raising and lowering of the soldering iron simply by moving the control handle, which is labor-saving and intuitive. The guide support mechanism (guide rod and sliding bearing) ensures that the soldering iron moves smoothly in the vertical direction during raising, lowering and pressing, without shaking or wobbling, thus providing a guarantee for applying uniform and stable heat sealing pressure.

[0025] 3. Thanks to the stable guiding mechanism and integrated temperature controller, the two key parameters of temperature and pressure during heat sealing can be precisely controlled. This ensures consistent conditions for each heat sealing operation, effectively guaranteeing uniform sealing strength and appearance quality, and avoiding defects caused by temperature fluctuations or uneven pressure.

[0026] 4. The cooling fan and optimized ventilation openings (such as louvers) work together to effectively dissipate the heat accumulated inside the casing in a timely manner, preventing the soldering iron and other electronic components from aging due to long-term high-temperature operation, thereby extending the service life of the entire device.

[0027] 5. This utility model can be managed as a dedicated workstation. Specifically, energy saving can be achieved through simple automatic control logic, such as installing a micro switch inside the casing that is linked to the operating handle or rotating shaft. When the operating handle switches the soldering iron to the storage position, the switch is triggered, automatically switching the soldering iron circuit to a disconnected or low-power standby state; when work is needed, lifting the handle automatically restores full power supply. This design fundamentally overcomes the energy waste caused by the need for manual management of ordinary soldering irons and the resulting prolonged dry burning, achieving automated energy saving. At the same time, the integration and specialization of the device also make workbench management simpler and more standardized.

[0028] 6. The integrated and specialized nature of the equipment ensures a clean and orderly workbench, solving the problem of clutter caused by the random placement of traditional soldering irons and related tools, and meeting the requirements of lean management in modern factories.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0038] Example 1

[0039] As attached Figure 1-5 As shown, this embodiment provides a lifting-type heat-sealing device for transparent paper strip boxes, including a housing 1, a soldering iron 2, a lifting mechanism, a control handle 5, a guide support mechanism, a cooling fan, a temperature controller 10, a protective cover 11, and related auxiliary components. The soldering iron 2 has a rectangular panel and is used to heat-seal the folded transparent paper strip boxes.

[0040] The lifting mechanism of this device includes a rotating shaft 3 rotatably supported within the housing 1, and a cam 4 coaxially fixedly sleeved on the rotating shaft 3. The lower surface of the soldering iron 2 abuts against the outer contour of the cam 4. The outer contour of the cam 4 is elliptical or eccentrically circular. By rotating the rotating shaft 3, the cam 4 is driven to rotate, realizing the reciprocating lifting and lowering of the soldering iron 2 in the vertical direction, thereby switching the soldering iron 2 between the working position and the storage position (see attached diagram). Figure 4 Appendix Figure 5 The operating handle 5 is located outside the housing 1 and connected to one end of the rotating shaft 3. The operating handle 5 can drive the rotating shaft 3 and the cam 4 to rotate, thereby driving the soldering iron 2 to rise and fall (see attached image). Figure 1 Appendix Figure 2 ).

[0041] As attached Figure 3 As shown, a guide support mechanism is provided between the soldering iron 2 and the housing 1. The guide support mechanism includes four vertically arranged guide rods 6, which are fixed at the four corners of the soldering iron 2. The lower ends of the guide rods 6 extend into and slide into the sliding bearings 7 fixed on the support 13. The sliding bearings 7 are sleeve-type structures, and the guide rods 6 are inserted into them to form a sliding pair, with a clearance fit between them.

[0042] During the lifting and lowering process, the guide rod 6 maintains a sliding engagement with the sliding bearing 7. When the soldering iron 2 is in the retracted position, the guide rod 6 descends until its lower end directly abuts against the preset limiting surface on the support 13, thereby achieving precise vertical positioning of the soldering iron 2. At the same time, the inner wall of the sliding bearing 7 provides circumferential (radial) constraint for the guide rod 6, jointly ensuring stable support for the soldering iron 2 in the non-working state and effectively preventing swaying in any direction.

[0043] When the operating handle 5 drives the cam 4 to rotate, lifting the soldering iron 2 to the working position, the guide rod 6 slides upward relative to the sliding bearing 7. During this process, under the precise guidance and coordinated limiting of their respective sliding bearings 7, the four guide rods 6 ensure that the soldering iron 2 can move smoothly in a strictly vertical direction throughout the entire lifting stroke, without any wobble or jamming.

[0044] To reduce motion friction resistance and improve wear resistance, a low-friction coating can be plated on the surface of the guide rod (6), or a high-temperature self-lubricating material (such as polytetrafluoroethylene or embedded bronze graphite bushing) can be directly lined on the inner wall of the sliding bearing (7), thereby ensuring the long-term stability and reliability of the entire lifting mechanism.

[0045] A cooling fan (not shown in the figure) is installed inside the casing 1, and louvered ventilation openings 9 are opened on the side wall of the casing. The fan 8 and the ventilation openings 9 work together to dissipate the heat accumulated inside the casing in a timely manner. The temperature of the soldering iron 2 is monitored and controlled in real time by a temperature controller 10 to ensure that the heat sealing temperature is kept within the preset range, thereby ensuring uniform sealing strength and stable appearance quality. The protective cover 11 can be opened and closed and installed on the top of the casing 1. The cover has honeycomb-shaped heat dissipation holes 12. When the soldering iron 2 is stored, the protective cover 11 can isolate the high-temperature parts, effectively improving operational safety (see attached figure). Figure 1 Appendix Figure 2 ).

[0046] To achieve energy saving, this embodiment incorporates a microswitch within the housing 1, linked to the operating handle 5 or the rotating shaft 3. When the handle 5 is rotated to the retracted position, the microswitch is triggered, automatically disconnecting the soldering iron 2 circuit or switching it to a low-power standby mode. When the handle 5 is raised to the working position, the microswitch automatically restores full power supply, enabling rapid activation of the soldering iron 2. This design overcomes the drawbacks of traditional soldering irons that burn dry for extended periods, ensuring automated energy conservation and improving the tidiness of the work surface.

[0047] During operation, the operator only needs to manually turn the handle 5 to raise the soldering iron 2 to the working position. The guide rod 6 and the sliding bearing 7 ensure a smooth lifting process, and the temperature controller 10 maintains a constant heat-sealing temperature. The uniform pressure applied by the soldering iron 2 ensures a stable and reliable heat-sealing effect for the transparent paper. When storing, rotating the handle 5 lowers the soldering iron 2 into the protective cover 11, simultaneously triggering a microswitch to cut off power or enter low-power standby mode, preventing dry burning and saving energy. The cooling fan and vent 9 work together to dissipate heat, extending the lifespan of the soldering iron 2 and the internal components of the casing.

[0048] Through the above design, this embodiment ensures the safety of heat sealing operations and the reliability of sealing quality, while achieving energy saving, simple operation, and a clean and orderly workstation, fully demonstrating the specialization, integration, safety, and high efficiency of the device.

[0049] Of course, the above description is not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, alterations, additions or substitutions made by those skilled in the art within the scope of the present utility model should be protected by the present utility model.
