Description

Technical Field

[0001] The utility model relates to the technical field of tobacco packaging machines, in particular to a glue spray nozzle disassembly component. Background Art

[0002] The GDX1 packaging machine, developed by the Italian company GD in the 1980s, boasts a maximum production speed of 400 packs per minute and is currently the mainstream cigarette packaging machine used by Chinese cigarette manufacturers. The label glue application system used on these cigarette packs typically uses hot melt glue. Over time, hot melt glue nozzles can become clogged and experience poor glue discharge. Therefore, disassembly of the nozzles is necessary for cleaning and maintenance. However, because existing hot melt glue dispensers are mounted on a base with their centerline parallel to the base, and multiple devices are installed adjacent to each other on the base, the space between adjacent devices is limited, making it easy to damage removal tools or adjacent devices, increasing maintenance costs. Furthermore, the nozzles' irregular, polygonal shape makes it difficult to exert force during disassembly, making nozzle removal cumbersome, time-consuming, and inefficient. Utility Model Content

[0003] The utility model aims to provide a glue spray nozzle disassembly assembly, which is easy to operate, has high disassembly efficiency, and can reduce maintenance costs.

[0004] To achieve this purpose, the present invention adopts the following technical solutions:

[0005] Glue nozzle disassembly assembly, used to disassemble the nozzle on the hot melt adhesive mechanism, including:

[0006] a disassembly member, wherein an abutment cavity is provided in the disassembly member, an opening of the abutment cavity is provided on a first side wall of the disassembly member, and a cross-sectional shape of the abutment cavity opening is adapted to the nozzle, and an inner wall of the abutment cavity is capable of abutting against an outer peripheral wall of the nozzle;

[0007] A disassembly handle, wherein a first end of the disassembly handle is connected to a second side wall of the disassembly member that is away from the first side wall, and the nozzle can be disassembled by twisting the disassembly handle.

[0008] As a further technical solution, the abutment cavity is configured to be cylindrical, and the center line of the abutment cavity is collinear with the center line of the disassembly handle.

[0009] As a further technical solution, the cross-sectional area of the abutting cavity gradually decreases from the first side wall to the second side wall.

[0010] As a further technical solution, a first anti-slip portion is provided on the outer peripheral surface of the disassembly handle.

[0011] As a further technical solution, the disassembly handle is fixedly connected to the disassembly member;

[0012] Alternatively, the disassembly handle is detachably connected to the disassembly member.

[0013] As a further technical solution, the glue nozzle disassembly assembly further includes an auxiliary handle connected to the second end of the disassembly handle.

[0014] As a further technical solution, the auxiliary handle is configured to be rod-shaped and is connected to the disassembly handle at an angle.

[0015] As a further technical solution, the second end of the disassembly handle is provided with an auxiliary hole, and the auxiliary handle can be detachably inserted into the auxiliary hole.

[0016] As a further technical solution, the second end of the disassembly handle is set as an auxiliary part, and a connecting hole is correspondingly provided on the auxiliary handle. The auxiliary handle is detachably connected to the auxiliary part through the connecting hole.

[0017] As a further technical solution, a second anti-slip portion is provided on the outer wall of the auxiliary handle.

[0018] Compared with the prior art, the glue nozzle disassembly assembly provided by the present invention has the following technical advantages:

[0019] Since a disassembly part is connected to the second side wall, and the second side wall and the first side wall provided with the abutment cavity opening are arranged away from each other, when disassembling the nozzle, the disassembly part is first placed on the nozzle, and the outer wall of the nozzle is abutted against the inner wall of the abutment cavity. Then, the disassembly handle is twisted to drive the disassembly part to rotate, thereby driving the nozzle to rotate and remove the nozzle from the hot melt adhesive mechanism. During the entire disassembly process, the glue nozzle disassembly assembly is not restricted by the space between two adjacent hot melt adhesive mechanisms, thereby improving the convenience of disassembly of the nozzle. At the same time, during the nozzle disassembly process, the collision between the glue nozzle disassembly assembly and the hot melt adhesive mechanism can be reduced, thereby reducing the probability of collision damage to the glue nozzle disassembly assembly or the adjacent hot melt adhesive spraying device, thereby reducing maintenance costs. In addition, since the cross-sectional shape of the abutment cavity opening is set to correspond to the cross-sectional shape of the nozzle, when disassembling the nozzle, idling of the disassembly part can be avoided, thereby ensuring the disassembly effect and improving the disassembly efficiency.

It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0032] In the description of this embodiment, the terms "upper," "lower," "right," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0033] The overall structure of the hot melt adhesive device is as follows Figure 4 As shown, multiple hot melt adhesive mechanisms 20 are spaced apart and arranged on one side of the hot melt adhesive base 30 , and the center lines of the multiple hot melt adhesive mechanisms 20 are parallel to the bottom plate of the hot melt adhesive base 30 , and each hot melt adhesive mechanism 20 is provided with a nozzle 10 .

[0034] Combine Figures 1 to 3 As shown, the nozzle disassembly assembly is used to disassemble the nozzle 10 from the hot melt adhesive mechanism 20. It is easy to operate, has high disassembly efficiency, and can reduce maintenance costs. Specifically, the nozzle disassembly assembly includes a disassembly member 100 and a disassembly handle 200. The disassembly member 100 is provided with an abutment cavity 110. The opening of the abutment cavity 110 is provided on the first side wall 101 of the disassembly member 100. The cross-sectional shape of the opening of the abutment cavity 110 is adapted to the nozzle 10. The inner wall of the abutment cavity 110 can abut against the outer peripheral wall of the nozzle 10. The first end of the disassembly handle 200 is connected to the second side wall 102 of the disassembly member 100, which is opposite to the first side wall 101. The nozzle 10 can be disassembled by twisting the disassembly handle 200.

[0035] Since the second side wall 102 is connected to the disassembly piece 100, and the second side wall 102 and the first side wall 101 provided with the opening of the abutting cavity 110 are arranged to be separated from each other, when disassembling the nozzle 10, the disassembly piece 100 is first placed on the nozzle 10, and the outer wall of the nozzle 10 is abutted against the inner wall of the abutting cavity 110. Then, the disassembly handle 200 is twisted to drive the disassembly piece 100 to rotate, thereby driving the nozzle 10 to rotate and remove the nozzle 10 from the hot melt adhesive mechanism 20. During the entire disassembly process, the glue nozzle disassembly assembly is not restricted by the space between two adjacent hot melt adhesive mechanisms 20, thereby improving the convenience of disassembly of the nozzle 10. At the same time, during the disassembly process of the nozzle 10, the collision between the glue nozzle disassembly assembly and the hot melt adhesive mechanism 20 can be reduced, thereby reducing the probability of collision damage to the glue nozzle disassembly assembly or the adjacent hot melt adhesive spraying device, thereby reducing maintenance costs. In addition, since the cross-sectional shape of the opening of the abutting cavity 110 is set to correspond to the cross-sectional shape of the nozzle 10, when the nozzle 10 is disassembled, idling of the disassembly component 100 can be avoided, thereby ensuring the disassembly effect and improving the disassembly efficiency.

[0036] Preferably, the abutting cavity 110 is configured to be cylindrical, and the center line of the abutting cavity 110 is collinear with the center line of the disassembly handle 200 .

[0037] In this embodiment, the cross-sectional shape of the nozzle 10 is configured as a regular hexagon. Correspondingly, the cross-sectional shape of the abutment cavity 110 from the first sidewall 101 to the second sidewall 102 is configured as a regular hexagon. This ensures that after the disassembly member 100 is inserted into the nozzle 10, all portions of the outer peripheral wall of the nozzle 10 abut against the inner wall of the abutment cavity 110, thereby ensuring effective disassembly. By aligning the centerline of the abutment cavity 110 with the centerline of the disassembly handle 200, the disassembly member 100 is uniformly stressed during rotation of the disassembly handle 200, ensuring effective disassembly of the target nozzle 10 while preventing mechanical damage to the disassembly member 100 due to uneven stress.

[0038] Preferably, the cross-sectional area of the abutment cavity 110 gradually decreases from the first side wall 101 to the second side wall 102. This arrangement allows nozzles 10 of different sizes to be disassembled by abutting against corresponding locations on the inner wall of the abutment cavity 110. That is, the same disassembly member 100 can disassemble multiple nozzles 10 of different sizes, thereby expanding the applicability of the nozzle disassembly assembly.

[0039] Preferably, a first anti-slip portion 210 is provided on the outer circumference of the removal handle 200. The first anti-slip portion 210 prevents slipping when twisting the removal handle 200, thereby avoiding difficulty in exerting force. Depending on actual needs, the first anti-slip portion 210 can be configured as a plurality of spaced anti-slip protrusions or anti-slip grooves; or it can be directly configured as an anti-slip sleeve and fitted over the removal handle 200.

[0040] Furthermore, the disassembly handle 200 is fixedly connected to the disassembly member 100. This minimizes the loss of twisting force when turning the disassembly handle 200, thereby further improving the efficiency of disassembling the nozzle 10. The fixed connection method can be welding, bonding, or integral molding. In this embodiment, the disassembly handle 200 and the disassembly member 100 are integrally molded.

[0041] In some other embodiments, the disassembly handle 200 is detachably connected to the disassembly member 100. While ensuring the disassembly effect, after the disassembly is completed, the disassembly handle 200 is removed from the disassembly member 100, which can reduce the space volume of the glue nozzle disassembly assembly and facilitate the storage of the glue nozzle disassembly assembly. The detachable connection method can be selected as plug-in, specifically, a plug-in hole is provided on the second side wall 102, the center of the plug-in hole is concentrically arranged with the center line of the abutment cavity 110, the cross-sectional shape of the plug-in hole is set to a polygon or an ellipse, and the cross-sectional shape of the first end of the disassembly handle 200 is set corresponding to the plug-in hole. When the first end of the disassembly handle 200 is inserted into the plug-in hole, the nozzle 10 can be disassembled; it can also be set as a threaded connection, specifically, a first threaded hole is provided on the second side wall 102, and the rotation direction of the internal thread provided on the inner side of the first threaded hole is opposite to the rotation direction of the connecting thread on the inner side of the nozzle 10. The first end of the disassembly handle 200 is provided with an external thread corresponding to the first threaded hole. When the first end of the disassembly handle 200 is threadedly connected to the first threaded hole, the nozzle 10 can be disassembled; in addition, a suitable detachable connection method can be selected according to actual needs.

[0042] Preferably, the glue nozzle disassembly assembly further includes an auxiliary handle 300, which is connected to the second end of the disassembly handle 200. The auxiliary handle 300 can be fixedly connected to the disassembly handle 200 to reduce the loss of twisting force, thereby further improving the disassembly efficiency of the nozzle 10. The fixed connection method can be selected from welding, bonding or one-piece molding. Alternatively, the auxiliary handle 300 can be detachably connected to the disassembly handle 200. When the auxiliary handle 300 is connected to the second end of the disassembly handle 200, it can assist the disassembly handle 200 to complete the disassembly of the nozzle 10 more quickly; when the disassembly of the nozzle 10 is completed, the auxiliary handle 300 can be removed from the second end of the disassembly handle 200, thereby reducing the spatial volume of the glue nozzle disassembly assembly and facilitating the storage of the glue nozzle disassembly assembly.

[0043] Preferably, the auxiliary handle 300 is configured as a rod and is connected to the disassembly handle 200 at an angle, so as to avoid relative rotation between the auxiliary handle 300 and the disassembly handle 200 when the auxiliary handle 300 is twisted, thereby affecting the disassembly of the nozzle 10 .

[0044] When the auxiliary handle 300 is detachably connected to the disassembly handle 200, it can be configured as follows: the second end of the disassembly handle 200 is provided with an auxiliary hole 220, and the auxiliary handle 300 is detachably inserted into the auxiliary hole 220. By inserting the auxiliary handle 300 into the auxiliary hole 220, the nozzle 10 can be disassembled.

[0045] Alternatively, the second end of the disassembly handle 200 may be configured as an auxiliary portion, and a corresponding connecting hole may be provided on the auxiliary handle 300, so that the auxiliary handle 300 can be detachably connected to the auxiliary portion through the connecting hole. Specifically, the cross-sectional shape of the auxiliary portion may be configured as a polygon or an ellipse, and the cross-sectional shape of the connecting hole may be configured to correspond to the auxiliary portion. When the auxiliary handle 300 is inserted into the second end of the disassembly handle 200 through the connecting hole, the nozzle 10 can be disassembled. Alternatively, a second threaded hole may be configured as the connecting hole, and the internal thread provided on the inner side of the second threaded hole has a direction of rotation opposite to that of the connecting thread on the inner side of the nozzle 10. The second end of the disassembly handle 200 may be configured with an external thread corresponding to the second threaded hole. When the second end of the disassembly handle 200 is threadedly connected to the second threaded hole, the nozzle 10 can be disassembled. In addition to this, a suitable detachable connection method may be selected according to actual needs.

[0046] Preferably, a second anti-slip portion 310 is provided on the outer wall of the auxiliary handle 300. The second anti-slip portion 310 prevents slipping when turning the auxiliary handle 300, thereby preventing difficulty in exerting force. Depending on actual needs, the second anti-slip portion 310 can be configured as a plurality of spaced anti-slip protrusions or grooves, or directly configured as an anti-slip sleeve that fits over the auxiliary handle 300.

[0047] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
