[0002] The GDX6S cigarette box packaging machine primarily uses inner lining paper, label paper, and sealing paper to complete the soft box packaging process. With a production capacity of 600 packs / minute, it is a key piece of equipment ensuring efficient cigarette production. In actual production, label paper conveying malfunctions account for a relatively high proportion of equipment failures. Therefore, during the daily maintenance and repair of the GDX6S cigarette box packaging machine, it is often necessary to disassemble, install, and adjust the suction drum, gluing drum, label paper glue cylinder, and gluing roller, and to check their transmission components to ensure the normal conveying and packaging of the label paper.

[0003] The label paper glue cylinder requires daily disassembly for cleaning and maintenance. The coupling, connected to the label paper glue cylinder by locking bolts, is a crucial transmission component of the label paper glue cylinder's mixing system. Current technology lacks specialized disassembly and assembly tools for the label paper glue cylinder coupling. Furthermore, the coupling's compact installation space and strong interrelationship with surrounding components limit operating space. At least two maintenance personnel are required to disassemble surrounding components using various general-purpose tools before disassembling the coupling. This disassembly and assembly process is time-consuming and labor-intensive, not only extending equipment downtime and impacting production efficiency but also potentially causing damage to the coupling or surrounding components due to improper operation, further increasing maintenance costs.

[0004] Therefore, there is an urgent need to propose a coupling assembly and disassembly tool to solve the above problems. Utility Model Content

The wrench includes a connected wrench rod and a wrench head, the wrench head being used for circumferential limiting engagement with the bolt sleeve. The sleeve is fitted onto the wrench rod and can engage circumferentially with the anti-rotation sleeve; a handle is also connected to the outer wall of the sleeve.

[0008] In some optional embodiments, the bolt sleeve has a first limiting groove at one end near the locking bolt. The first limiting groove is adapted to the shape of the locking bolt and can be sleeved on the locking bolt.

[0009] In some alternative embodiments, the inner wall of the first limiting groove near the locking bolt is chamfered.

[0010] In some alternative embodiments, the bolt sleeve is detachably connected to the wrench head.

[0011] In some optional embodiments, the bolt sleeve has a second limiting groove adapted to the shape of the wrench head, and the wrench head can be inserted into the second limiting groove.

[0016] In some alternative embodiments, the wrench further includes a handle portion that is angled to the end of the wrench handle away from the wrench head.

[0017] The beneficial effects of this utility model are:

[0018] This utility model provides a coupling assembly / disassembly fixture. The coupling is connected to a label paper glue cylinder by a locking bolt. The fixture includes a bolt sleeve, an anti-rotation sleeve, a wrench, and a sleeve. The anti-rotation sleeve is used to circumferentially limit the coupling and has a clearance hole for exposing the locking bolt.

[0030] The embodiments of this utility model are described in detail below. 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] like Figure 1 and Figure 2As shown, this embodiment provides a coupling disassembly and assembly tool for disassembling and assembling the coupling 100 of the label paper glue cylinder. It should be noted that the coupling 100 is connected to the label paper glue cylinder by locking bolts. Its installation space is compact and it is closely related to surrounding components, resulting in limited operating space. At least two maintenance personnel are required to use a variety of general-purpose tools to disassemble some surrounding components before the coupling 100 can be disassembled. The disassembly and assembly process is time-consuming and labor-intensive, which not only prolongs the equipment downtime for maintenance and affects production efficiency, but may also cause damage to the coupling 100 or surrounding components due to improper operation, further increasing maintenance costs.

[0038] To solve the above problems, the coupling assembly and disassembly tooling of this embodiment includes a bolt sleeve 1, an anti-rotation sleeve 2, a wrench 3, and a sleeve 4. The anti-rotation sleeve 2 is used to circumferentially limit the coupling 100 and has a relief hole 21 for exposing the locking bolt. The bolt sleeve 1 is rotatably inserted into the relief hole 21 and can circumferentially limit the locking bolt. The wrench 3 includes a connected wrench rod 31 and a wrench head 32. The wrench head 32 is used to circumferentially limit the bolt sleeve 1. The sleeve 4 is sleeved on the wrench rod 31 and can circumferentially limit the anti-rotation sleeve 2. A handle 5 is also connected to the outer wall of the sleeve 4.

[0039] During operation, firstly, the anti-rotation sleeve 2 is circumferentially limited to the coupling 100; then, the bolt sleeve 1 is inserted into the clearance hole 21 of the anti-rotation sleeve 2 and limited to the locking bolt; then, the wrench handle 31 is inserted into the sleeve 4, and the wrench head 32 is circumferentially limited to the bolt sleeve 1, and the sleeve 4 is circumferentially limited to the anti-rotation sleeve 2; finally, the operator holds the handle 5 with one hand, fixes the coupling 100 through the sleeve 4, and rotates the wrench 3 with the other hand to tighten the locking bolt through the bolt sleeve 1, thereby achieving the tightening or loosening of the locking bolt, thus realizing the installation or removal of the coupling 100.

[0040] By adopting the aforementioned coupling assembly and disassembly fixtures, the structure and installation space of the label paper glue cylinder coupling 100 can be adapted. Within a limited operating space, reliable fixing of the coupling 100 and convenient disassembly and assembly of the locking bolts can be achieved, thereby improving the ease of operation for disassembling and assembling the coupling 100 and increasing equipment maintenance efficiency. Furthermore, single-person operation is possible, which helps reduce labor costs. The precision and safety of disassembly and assembly operations are optimized, avoiding damage to the coupling 100 and surrounding components due to improper operation, thus reducing equipment maintenance costs. The daily maintenance and inspection process is simplified, improving the convenience of cleaning and maintaining the label paper glue cylinder, ensuring the transmission stability of the mixing system, and thus ensuring the normal operation of the label paper conveying and soft box packaging processes.

[0041] In this embodiment, the handle 5 extends in a direction perpendicular to the axis of the sleeve 4, forming a force-saving lever structure, which can reduce the operating force and make it easier to hold firmly, thereby preventing the coupling 100 from rotating with the locking bolt, further improving the ease of disassembly and assembly, and reducing the difficulty of operation.

[0042] In some optional embodiments, the bolt sleeve 1 has a first limiting groove 11 at one end near the locking bolt. The first limiting groove 11 is adapted to the shape of the locking bolt and can be sleeved onto the locking bolt. The precise fit between the first limiting groove 11 and the shape of the locking bolt enables quick sleeve positioning, adapts to compact installation spaces, eliminates the need to disassemble surrounding components, and improves disassembly and assembly efficiency. On the other hand, it forms a reliable limit, preventing the bolt from slipping or shifting during disassembly and assembly, ensuring stable torque transmission, improving operational accuracy, and reducing the risk of component damage.

[0043] Furthermore, the inner wall of the first limiting groove 11 near the locking bolt is chamfered. The chamfer design reduces the difficulty of aligning the first limiting groove 11 with the locking bolt, adapts to compact operating spaces, enables quick and accurate connection, reduces connection resistance, improves the smoothness of disassembly and assembly, and further enhances the ease of operation.

[0044] In some optional embodiments, the bolt sleeve 1 and the wrench head 32 are detachably connected. The detachable design of the bolt sleeve 1 and the wrench head 32 allows the operator to adaptably replace the corresponding model of the bolt sleeve 1 to accommodate different specifications of locking bolts, improving the versatility of the tooling; it eliminates the need to equip a complete set of tools separately for different locking bolts, reducing usage costs and further optimizing disassembly and assembly efficiency.

[0045] Specifically, the bolt sleeve 1 has a second limiting groove that matches the shape of the wrench head 32, into which the wrench head 32 can be inserted. The second limiting groove precisely matches the shape of the wrench head 32, forming a stable limit after insertion, preventing relative slippage during disassembly and assembly, and ensuring efficient torque transmission. The structure is compact and without redundancy, suitable for narrow operating spaces, and the connection method is simple and convenient, which can improve the convenience of tooling assembly and disassembly, and facilitate the storage or replacement of different models of bolt sleeves 1.

[0046] Furthermore, the end of the wrench head 32 near the second limiting groove is chamfered, which reduces the difficulty of insertion and alignment with the second limiting groove, adapts to the compact operating space, and achieves quick and accurate docking; it avoids sharp edges from scratching the groove wall, reduces insertion resistance, and ensures a tight fit after insertion and stable torque transmission, further reducing the difficulty of operation and improving the convenience of operation.

[0047] In some optional embodiments, the end face of the coupling 100 is provided with a limiting part 110, and the anti-rotation sleeve 2 is provided with a third limiting groove 22 that is adapted to the shape of the limiting part 110, for insertion and engagement with the limiting part 110, so as to achieve circumferential limiting of the coupling 100, preventing the coupling 100 from rotating when the locking bolts are removed or installed, and ensuring operational accuracy; its structure is compact and can be adapted to narrow installation space without additional avoidance, achieving efficient disassembly and assembly; the close-fitting limiting reduces relative friction between components, further reducing the risk of damage to the coupling 100.

[0048] In some optional embodiments, the anti-rotation sleeve 2 is detachably connected to the sleeve 4, and different models of anti-rotation sleeve 2 can be replaced to adapt to couplings 100 of different sizes and structures, further improving the tooling versatility; and with the detachable bolt sleeve 1, it is easy to achieve accurate matching of tooling with coupling 100 and locking bolts in a narrow operating space, reducing assembly difficulty.

[0049] Specifically, the inner wall of the anti-rotation sleeve 2 is provided with a limiting block 23, and the sleeve 4 is provided with a fourth limiting groove 41 that matches the shape of the limiting block 23 for insertion and engagement with the limiting block 23. The limiting block 23 and the fourth limiting groove 41 are precisely inserted to form a bidirectional limiting, which can prevent the anti-rotation sleeve 2 and the sleeve 4 from rotating or displacing relative to each other, ensuring stable transmission of anti-rotation torque; the structure is compact and without redundancy, suitable for narrow operating spaces, and the connection method is simple, making disassembly and assembly convenient and efficient.

[0050] In some optional embodiments, the wrench 3 also includes a handle 33, which is connected at an angle to the end of the wrench handle 31 away from the wrench head 32, forming a force-saving lever structure. This reduces the torque required for disassembly and assembly, improves ease of operation, and provides a more reasonable grip force, enhancing operational stability and further adapting to efficient disassembly and assembly scenarios for single individuals.

[0051] In this embodiment, the handle 33 and the wrench lever 31 are connected in a T-shape to form a symmetrical force-bearing structure, which facilitates gripping and operation; the horizontal handle is adapted to the compact space, avoids interference with surrounding components, and has a larger gripping area and stronger stability, further improving the convenience of operation and the efficiency of disassembly and assembly.

[0052] 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.
