[0002] The YB95 carton transparent paper packaging machine wraps a layer of transparent paper around the outside of rigid cigarette packs, providing a seal against moisture, enhancing the sensory quality of the cigarettes, and extending their shelf life. Its structure consists of five parts: a cigarette pack supply system, a transparent paper supply system, a drawstring supply system, a wrapping and heat-sealing system, and an output system. The transparent paper supply system includes a roll holder, feeding rollers, a transparent paper cutter, and a fixed bottom knife. The function of the transparent paper supply system is to unfold the transparent paper on the roll holder under the action of the feeding rollers, through various stages of rollers, and then cut it with the rotating transparent paper cutter and the fixed bottom knife, thus cutting the transparent paper and conveying the cut paper horizontally to the paper pulling device.

[0003] However, the existing transparent paper supply system does not secure the transparent paper reliably, causing it to easily fall off the transparent paper roll rack. This can lead to deformation or even damage of the transparent paper roll due to collisions with other structures, ultimately affecting the packaging quality of the transparent paper and increasing raw material waste.

[0004] Therefore, how to provide a transparent paper roll fixing device for packaging machines has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0028] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0029] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0030] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0031] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0032] like Figures 1 to 3 As shown, this utility model embodiment provides a transparent paper roll fixing device for a packaging machine, including: a base plate 1, a fixing component 2, a driving component 3, and a limiting component 4.

[0033] The fixing assembly 2 includes a first fixing plate 21, a second fixing plate 22, a first roll frame 23, a second roll frame 24, and a moving rod 25. The first end of the first fixing plate 21 and the first end of the second fixing plate 22 are respectively perpendicularly connected to the two ends of the base plate 1. The first end of the moving rod 25 passes through the first fixing plate 21 and is connected to the first end of the first roll frame 23 to drive the second roll frame 24 to move. The first end of the second roll frame 24 is connected to the second end of the second fixing plate 22. The first roll frame 23 and the second roll frame 24 are used to fix the transparent paper roll 7.

[0034] Specifically, the first roll holder 23 and the second roll holder 24 are located on both sides of the transparent paper roll 7 and are inserted into the inner wall of the transparent paper roll 7, thereby fixing the transparent paper roll 7.

[0035] The drive assembly 3 is mounted on the first fixed plate 21 and connected to the moving rod 25. The drive assembly 3 is used to drive the moving rod 25 to move.

[0036] When it is necessary to install the transparent paper roll 7, the drive assembly 3 drives the moving rod 25 to move toward the second fixing plate 22. At this time, the distance between the first roll frame 23 and the second roll frame 24 gradually decreases until they come into contact with the transparent paper roll 7, so as to fix the transparent paper roll 7.

[0037] When it is necessary to loosen the transparent paper roll 7, the drive assembly 3 drives the moving rod 25 to move away from the second fixed plate 22. At this time, the distance between the first roll frame 23 and the second roll frame 24 gradually increases, so as to release the fixation of the transparent paper roll 7.

[0038] Limiting component 4 is used to restrict the movement of moving rod 25.

[0039] This invention vertically connects the first end of the first fixing plate 21 and the first end of the second fixing plate 22 to both ends of the base plate 1, respectively. The first end of the moving rod 25 passes through the first fixing plate 21 and is connected to the first end of the first roll frame 23. The first end of the second roll frame 24 is connected to the second end of the second fixing plate 22. The driving component 3 is mounted on the first fixing plate 21 and connected to the moving rod 25. This invention enables the moving rod 25 to drive the first roll frame 23 to move, so that the first roll frame 23 cooperates with the second roll frame 24 to fix and release the transparent paper roll 7. The limiting component 4 restricts the movement of the moving rod 25, thereby avoiding the problem of unstable fixing of the transparent paper roll 7 in existing transparent paper supply systems, which causes the transparent paper roll 7 to fall and be damaged. This reduces production costs and improves the utilization rate of raw materials.

[0040] In one embodiment of the transparent paper roll fixing device for the packaging machine of this utility model, in order to enable the moving rod 25 to be stably set on the first fixing plate 21, a through hole is provided on the first fixing plate 21, and the first end of the moving rod 25 passes through the through hole and is connected to the first end of the first roll frame 23.

[0041] In one embodiment of the transparent paper roll fixing device for the packaging machine of this utility model, such as Figures 1 to 3 As shown, the moving rod 25 has a groove 26.

[0042] The limiting component 4 includes a limiting post 41, a limiting plate 42, and a sliding groove 43. The sliding groove 43 is disposed on the first fixed plate 21 and communicates with the through hole. The limiting post 41 is slidably disposed in the sliding groove 43 and inserted into the groove 26. The limiting plate 42 is located on the sliding groove 43.

[0043] It should be noted that the limiting component 4 of this utility model can be used to limit the moving rod 25 when the driving component 3 stops driving the moving rod 25. In this embodiment, the groove 26 can be an annular groove or a circular groove. When the driving component 3 stops driving the moving rod 25, the operator inserts the limiting post 41 into the groove 26 and fixes the limiting plate 42 on the slide groove 43, thereby achieving the limiting effect on the moving rod 25.

[0044] The limiting component 4 of this utility model can also continuously limit the movement rod 25. In this embodiment, the groove 26 is an annular groove, so even if the movement rod 25 rotates, the limiting post 41 will not affect the operation of the movement rod 25.

[0045] This invention sets a sliding groove 43 on a first fixed plate 21, and the sliding groove 43 is connected to a through hole. A limiting post 41 is slidably set in the sliding groove 43 and inserted into a groove 26. A limiting plate 42 is located on the sliding groove 43. By inserting the limiting post 41 into the groove 26, the limiting plate 42 is fixed on the sliding groove 43, thereby achieving the limiting effect on the moving rod 25. Even if the drive assembly 3 stops working, the limiting post 41 prevents the moving rod 25 from moving, avoiding the falling of the transparent paper roll 7, effectively avoiding the waste of raw materials and the related quality risks.

[0046] In one embodiment of the transparent paper roll fixing device for the packaging machine of this utility model, such as Figure 3 As shown, the limiting component 4 also includes mounting holes and fastening bolts 44. The mounting holes are located on both sides of the slide groove 43, and the fastening bolts 44 pass through the limiting plate 42 and are threadedly connected to the mounting holes.

[0047] This utility model places the mounting holes on both sides of the slide groove 43, and the fastening bolts 44 pass through the limiting plate 42 and are threadedly connected to the mounting holes, thereby making the limiting plate 42 stably fixed on the first fixing plate 21, so that the limiting post 41 can be stably inserted.

[0048] In one embodiment of the transparent paper roll fixing device for the packaging machine of this utility model, such as Figure 1 and Figure 2 As shown, the fixing component 2 also includes a spring 27, the first end of which is connected to the second fixing plate 22, and the second end of which is connected to the first end of the second drum frame 24.

[0049] This utility model connects the first end of the spring 27 to the second fixing plate 22 and the second end of the spring 27 to the first end of the second roll frame 24. Through the action of the spring 27, the position of the transparent paper roll 7 can be adjusted appropriately, thereby improving the practicality of the transparent paper roll fixing device for packaging machines.

[0050] In one embodiment of the transparent paper roll fixing device for the packaging machine of this utility model, such as Figure 1 and Figure 2 As shown, a rotating handwheel 5 is provided at the second end of the moving rod 25 to facilitate adjustment of the position of the moving rod 25.

[0052] The drive assembly 3 includes a drive cylinder 31 and a push plate 32. The drive cylinder 31 is fixed on the first fixed plate 21. The output shaft of the drive cylinder 31 is connected to the push plate 32. The push plate 32 is connected to the moving rod 25, and the top of the push plate 32 is located between the fixed ring 6 and the rotating handwheel 5.

[0053] This invention fixes the drive cylinder 31 on the first fixed plate 21, connects the output shaft of the drive cylinder 31 to the push plate 32, connects the push plate 32 to the moving rod 25, and positions the top of the push plate 32 between the fixed ring 6 and the rotating handwheel 5. Through the continuous operation of the drive cylinder 31, the moving rod 25 is always kept in the preset position, thereby ensuring that the first roll frame 23 and the second roll frame 24 continuously fix the transparent paper roll 7, thus guaranteeing the stability of the transparent paper roll fixing device of the packaging machine of this invention during operation.

[0054] In one embodiment of the transparent paper roll fixing device for the packaging machine of this utility model, such as Figure 2 As shown, the first fixing plate 21 is also provided with a sliding hole 28.

[0055] The drive assembly 3 also includes a guide rod 33, the first end of which is connected to the sliding hole 28, and the second end of which is connected to the bottom end of the push plate 32.

[0056] This invention connects the first end of the guide rod 33 to the sliding hole 28 and the second end of the guide rod 33 to the bottom end of the push plate 32. The guide rod 33 can limit the movement direction of the push plate 32, thereby improving the stability of the push plate 32.
