Description

Technical Field

[0001] This utility model relates to the field of tobacco machinery technology, and in particular to a lifting device for packaging machine components. Background Technology

[0002] In modern tobacco industry production, the GD packaging machine, as a core production piece of equipment, utilizes a modular design to enable the combined operation of multiple components, ensuring the large-scale production needs of tobacco packaging. However, the dense and interwoven layout of the machine's components presents significant challenges to equipment maintenance.

[0003] For example, the second pusher of a GD packaging machine requires regular maintenance and precision calibration after long-term operation. However, the second pusher is surrounded and obstructed by other components, resulting in extremely limited working space and a complex structural layout, which restricts maintenance operations. Currently, tobacco factories generally perform maintenance without removing the second pusher component. However, due to the component's own structure and the spatial obstruction from surrounding parts, the range of operations for maintenance personnel is significantly reduced. This not only leads to high workload and low efficiency but also makes it difficult to guarantee maintenance accuracy, resulting in unsatisfactory maintenance outcomes. More importantly, the confined working space easily leads to operational errors, posing significant safety hazards and seriously affecting the safety and reliability of equipment maintenance.

[0004] Therefore, there is an urgent need to propose a lifting device for packaging machine components to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve or at least alleviate some or all of the aforementioned problems. Therefore, the purpose of this invention is to provide a packaging machine component hoisting device to enable the hoisting of components in confined spaces, reduce the operational difficulty for maintenance personnel, improve equipment maintenance efficiency, and eliminate safety hazards.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A packaging machine component hoisting device, comprising:

[0008] A connector is configured to be detachably connected to the component to be lifted. When the two are connected, the connector fits snugly and is rigidly connected to the component to be lifted, and a first lifting component is provided on the top of the connector.

[0009] The lifting assembly includes a bracket, a lifting component, a drive assembly, and a second lifting component. The lifting component is movably connected to the bracket, and the second lifting component is connected to the lifting component. The second lifting component is detachably connected to the first lifting component. The drive assembly is mounted on the bracket, and its output end is connected to the lifting component for driving the lifting component to lift upward.

[0010] In some optional embodiments, the component to be hoisted is provided with a plurality of first threaded holes, the connector is provided with second threaded holes corresponding to at least some of the positions of the first threaded holes on the component to be hoisted, and the packaging machine component hoisting device further includes locking bolts corresponding one-to-one with the second threaded holes, the locking bolts being able to thread into the corresponding second threaded holes and the first threaded holes.

[0011] In some optional embodiments, the first lifting component is a lifting ring, with at least two lifting rings protruding from the top of the connector at intervals, and the second lifting component is a lifting hook, with each lifting hook corresponding to one of the lifting rings.

[0012] In some alternative embodiments, the lifting assembly further includes a bearing swivel connected between the lifting member and the second lifting member.

[0013] In some alternative embodiments, the lifting member is rotatably connected to the support.

[0014] In some alternative embodiments, the support includes a horizontal portion and a vertical portion connected at an angle, and the lifting member is rotatably connected to the vertical portion.

[0015] In some alternative embodiments, the drive assembly is tilted to form a triangular support structure with the vertical portion and the lifting member.

[0016] In some alternative embodiments, the drive assembly includes a pneumatic cylinder or a hydraulic cylinder.

[0017] In some alternative embodiments, the two ends of the lifting member are located on both sides of the support, and a counterweight is provided at the end away from the second lifting member.

[0018] In some alternative embodiments, the counterweight includes a counterweight box containing fluid, the volume of which is 1 / 3 to 2 / 3 of the capacity of the counterweight box.

[0019] The beneficial effects of this utility model are:

[0020] This utility model provides a packaging machine component lifting device, including a connector and a lifting assembly. The connector is configured to be detachably connected to the component to be lifted. When connected, the connector is in close contact with and rigidly connected to the component to be lifted, and a first lifting element is provided on the top of the connector. The lifting assembly includes a bracket, a lifting element, a drive assembly, and a second lifting element. The lifting element is movably connected to the bracket, and the second lifting element is connected to the lifting element. The second lifting element is detachably connected to the first lifting element. The drive assembly is disposed on the bracket, and its output end is connected to the lifting element for driving the lifting element upward. During lifting, firstly, the connector is in close contact with and rigidly connected to the component to be lifted. Then, the second lifting elements are connected to each other. Finally, the drive assembly drives the lifting element upward, so that the component to be lifted moves upward with the connector.

[0021] The connector is rigidly attached to the component to be lifted, minimizing its footprint in confined spaces. This perfectly suits the cramped and complex working environment of the GD packaging machine, reducing installation difficulty in such confined spaces. Furthermore, the rigid connection ensures no relative displacement between the connector and the component during lifting, preventing swaying or shifting, guaranteeing lifting stability, and preventing collisions or safety hazards caused by loose connections. Simultaneously, the lifting assembly provides stable support through a bracket, and the drive assembly directly lifts the lifting components upwards. Combined with the detachable connection between the first and second lifting components, this enables rapid assembly and efficient lifting of components in confined spaces. It provides maintenance personnel with a spacious and safe working area, reducing operational difficulty, improving equipment maintenance efficiency, and eliminating safety hazards. This also helps shorten equipment downtime for maintenance, ensuring the continuity of tobacco production. Attached Figure Description

Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar parts or parts having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0030] In this invention, the terms "comprising," "including," "having," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0031] In this invention, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, in this invention, the character " / " generally indicates that the preceding and following related objects have an "and / or" relationship.

[0032] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," "fixed," "combined," "coupled," and "installed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; they can be a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For example, a direct connection refers to two parts or components being connected together without an intermediate component, while an indirect connection refers to two parts or components each being connected to at least one intermediate component, with the connection achieved through the intermediate component. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Furthermore, "connected" and "coupled" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0033] In this invention, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the value and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0034] In this invention, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can be performed by one part, one component, or a combination of multiple parts.

[0035] In this utility model, the terms "upper," "lower," "left," "right," "front," and "rear," etc., refer to the orientation or positional relationships shown in the accompanying drawings. They are used solely for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, in the context, it should be understood that when an element is mentioned as being "upper" or "lower" of another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as "upper side," "lower side," "left side," "right side," "front side," and "rear side" not only represent positive orientation but can also be understood as lateral orientation. For example, "above," "on top of," "upper side of," and "above" of the first feature and the second feature include the first feature being directly above, to the upper left, to the upper right, to the upper front, and to the upper rear of the second feature, or simply indicating that the first feature is at a higher horizontal level than the second feature. The terms "below," "under," "below," and "below" for "first feature" and "second feature" include situations where the first feature is directly below, to the lower left, to the lower right, in front of, or behind the second feature, or simply indicate that the first feature is at a lower horizontal level than the second feature. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.

[0036] like Figures 1-3As shown, this embodiment provides a packaging machine component hoisting device, including a connector 1 and a hoisting assembly 3. The connector 1 is configured to be detachably connected to the component 100 to be hoisted. When the two are connected, the connector 1 fits against and is rigidly connected to the component 100 to be hoisted, and a first hoisting component 2 is provided on the top of the connector 1. The hoisting assembly 3 includes a bracket 31, a hoisting component 32, a drive assembly 33, and a second hoisting component 34. The hoisting component 32 is movably connected to the bracket 31, and the second hoisting component 34 is connected to the hoisting component 32. The second hoisting component 34 is detachably connected to the first hoisting component 2. The drive assembly 33 is disposed on the bracket 31, and its output end is connected to the hoisting component 32 for driving the hoisting component 32 to lift upward. During hoisting, firstly, the connecting piece 1 is fitted and rigidly connected to the part 100 to be hoisted. Then, the second hoisting piece 34 is connected to the second hoisting piece 34. Finally, the hoisting piece 32 is driven upward by the drive assembly 33 so that the part 100 to be hoisted moves upward with the connecting piece 1.

[0037] The connector 1 is rigidly connected to the component 100 to be lifted, which minimizes its volume in confined spaces, perfectly adapting to the cramped and complex working environment of the GD packaging machine and reducing installation difficulty. Furthermore, the rigid connection ensures no relative displacement between the connector 1 and the component 100 during lifting, preventing component swaying or shifting, ensuring lifting stability, and preventing component collisions or safety hazards caused by loose connections. Simultaneously, the lifting assembly 3 provides stable support through the bracket 31, and the drive assembly 33 directly drives the lifting component 32 upwards. Combined with the detachable connection between the first lifting component 2 and the second lifting component 34, this enables rapid assembly and efficient lifting of components in confined spaces, providing maintenance personnel with a spacious and safe working area, reducing operational difficulty, improving equipment maintenance efficiency, and eliminating safety hazards. It also helps shorten equipment downtime for maintenance and ensures the continuity of tobacco production.

[0038] like Figure 1 and Figure 2As shown, in some optional embodiments, the component 100 to be lifted has multiple first threaded holes, and the connector 1 has second threaded holes 11 corresponding to at least some of the first threaded holes on the component 100 to be lifted. The packaging machine component lifting device also includes locking bolts that correspond one-to-one with the second threaded holes 11, and the locking bolts can be threadedly engaged with the corresponding second threaded holes 11 and first threaded holes. Utilizing the existing first threaded holes on the component 100 to be lifted eliminates the need for additional drilling or welding on the component, avoiding damage to the component structure; the threaded locking method provides a firm connection, further enhancing the rigid connection effect, ensuring no relative displacement during lifting, and improving lifting stability and safety; the detachable threaded connection is convenient to operate, adaptable to rapid assembly and disassembly in confined spaces, requiring no complex tools, reducing operational difficulty and intensity; the corresponding arrangement of multiple threaded holes can distribute the force, avoiding local stress concentration, making the force on the component 100 to be lifted and the connector 1 balanced, which is beneficial to improving the reliability of lifting.

[0039] In some optional embodiments, the first lifting component 2 is a lifting ring, with at least two lifting rings protruding from the top of the connecting component 1 at intervals, and the second lifting component 34 is a lifting hook, with each hook corresponding to a lifting ring. The matching structure of the lifting ring and the lifting hook is convenient to connect, can be quickly assembled, and multi-point lifting can distribute the force, protecting the connecting component 1 and the component 100 to be lifted, further ensuring lifting safety.

[0040] like Figure 2 As shown, in some optional embodiments, the lifting assembly 3 further includes a bearing swivel 35, which is connected between the lifting member 32 and the second lifting member 34. This allows the second lifting member 34 to rotate flexibly relative to the lifting member 32, eliminating torque stress and rope entanglement problems during lifting. This facilitates the adjustment of the orientation of the component 100 to be lifted in confined spaces, precisely avoiding surrounding obstructing components. Simultaneously, the bearing structure reduces rotational resistance, making operation easier and smoother, and improving the force balance of multi-point lifting, further ensuring lifting stability and safety, and adapting to the needs of precision component relocation.

[0041] The bearing ring 35 includes a first ring, a second ring, and a bearing. The first ring and the second ring are rotatably connected by the bearing. One of them is connected to the lifting member 32, and the other is connected to the second lifting member 34, so that the second lifting member 34 can rotate flexibly relative to the lifting member 32.

[0042] In some optional embodiments, the lifting component 32 is rotatably connected to the support 31, with the support 31 providing a pivot point for the lifting component 32. The output end of the drive assembly 33 is spaced apart from the pivot point, forming a lever structure. The component is lifted by driving the lifting component 32 to rotate upward, which is labor-saving and highly efficient. The rotary lifting mechanism allows for flexible adjustment of the component's lifting angle, adapting to optimized posture in confined spaces, accurately avoiding surrounding obstructions, further expanding the maintenance work space, simplifying the device structure, improving the flexibility and accuracy of lifting operations, and effectively ensuring the stability and safety of component relocation.

[0043] In some optional embodiments, the bracket 31 includes a horizontal portion 311 and a vertical portion 312 connected at an angle, with the lifting member 32 rotatably connected to the vertical portion 312. The horizontal portion 311 can be placed against the equipment or the ground for reliable fixation, while the vertical portion 312 provides a stable fulcrum for the lifting member 32, adapting to installation layouts in confined spaces and further optimizing operational flexibility within such spaces.

[0044] In some optional embodiments, the drive assembly 33 is tilted, forming a triangular support structure with the vertical part 312 and the lifting component 32. Utilizing the stability characteristics of a triangle, the structural rigidity during lifting can be improved, component swaying reduced, and lifting misalignment avoided in confined spaces. Furthermore, the tilted layout optimizes the drive force transmission path, making the drive more efficient and less labor-intensive, while reducing the space occupied by the drive assembly 33, avoiding interference with surrounding components, and adapting to compact working environments. This design balances structural stability and spatial adaptability, further ensuring the accuracy, safety, and ease of operation during component lifting.

[0045] Specifically, the drive assembly 33 includes a cylinder or hydraulic cylinder, which can form a triangular support structure with the vertical part 312 and the lifting component 32. It has the advantages of stable output force and rapid start and stop response, and can provide continuous and reliable driving force for the lifting component 32, ensuring the smooth lifting of components in a narrow space. It also has a compact structure, occupies little space, and is compatible with the overall compact layout of the device.

[0046] In some optional embodiments, the two ends of the lifting member 32 are located on both sides of the bracket 31, and the end away from the second lifting member 34 is provided with a counterweight 36, forming a balance lever structure. This structure can offset part of the weight of the component 100 to be lifted, reduce the load on the drive assembly 33, and make the lifting operation more labor-saving and efficient. At the same time, the counterweight balance design can reduce the tilting and swaying of the lifting member 32 when it rotates, significantly improving the stability and accuracy of lifting in confined spaces and preventing components from bumping into each other.

[0047] In some optional embodiments, the counterweight 36 includes a counterweight box containing fluid, the volume of which is 1 / 3 to 2 / 3 of the counterweight box's capacity. On the one hand, the counterweight weight can be flexibly adjusted by increasing or decreasing the fluid volume to adapt to different loads on the components 100 to be lifted, improving the device's versatility. On the other hand, the fluid volume being 1 / 3 to 2 / 3 of the counterweight box's capacity allows fluid to flow within the box; the fluid's flowability can buffer the impact force during lifting, reducing component sway and enhancing lifting stability in confined spaces. Furthermore, the counterweight box has a compact structure and convenient weight adjustment, eliminating the need to disassemble and replace counterweight blocks, reducing workload, and avoiding the adaptation limitations caused by fixed counterweights, thus balancing practicality and operational flexibility while ensuring component lifting safety.

[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
