Abstract
Description
Technical Field
[0001] This utility model relates to the field of cigarette manufacturing technology, and in particular to a transparent paper clamping and conveying device and a cigarette box packaging equipment. Background Technology
[0002] During the production process of cigarette boxes, a transparent paper packaging step is required. In the current packaging production process, the transparent paper of small boxes is pressed by the cooperation of an eccentric shaft, a limit screw and a pressure spring, which has problems such as complicated adjustment, easy fatigue and different pressure at both ends.
[0003] In the packaging process of the packaging unit, the clamping action of the small box transparent paper clamping roller relies on an eccentric shaft and a pressure spring. These components are prone to fatigue over time, resulting in inconsistent clamping effects. Furthermore, the uneven pressure at both ends of the clamping roller can cause the transparent paper to shift and vary in length during transport, leading to packaging deviations in the cigarette boxes. Maintenance and adjustments are complicated by issues such as complex eccentric shaft adjustments, easy fatigue of the pressure spring, and the need for frequent maintenance and adjustments, all of which affect cigarette packaging efficiency.

[0043] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0046] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only 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. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0047] This embodiment provides a transparent paper clamping and conveying device. The clamping and loosening of the rollers depends on the drive assembly 30, resulting in consistent clamping, longer service life, and easier adjustment and maintenance. Figure 1 and Figure 2 As shown, the transparent paper clamping and conveying device includes a fixed roller (not shown) and a movable mechanism. The fixed roller extends along a first direction (X direction in the figure) and is pivotally connected to a first frame (not shown). The movable mechanism includes a second frame 10, a movable roller 20, a drive assembly 30, and a sliding assembly 40. The movable roller 20 is arranged parallel to the fixed roller and pivotally connected to the sliding assembly 40. The sliding assembly 40 and the second frame 10 slide in a second direction (Y direction in the figure, which is perpendicular to the X direction). The output end of the drive assembly 30 is connected to the sliding assembly 40. The drive assembly 30 can drive the sliding assembly 40 to move along the second direction so that the movable roller 20 moves closer to or away from the fixed roller. The transparent paper passes between the fixed roller and the movable roller 20.
[0048] The aforementioned transparent paper clamping and conveying device uses the drive assembly 30 as the drive source for the sliding assembly 40, enabling the movable roller 20 to move closer to or further away from the fixed roller. Furthermore, the drive assembly 30 can apply constant pressure to the sliding assembly 40 when the movable roller 20 contacts the fixed roller, ensuring consistent clamping. The entire operation does not rely on springs and eccentric shafts, requires fewer parts, has a long service life for the drive assembly 30, and is easy to adjust and maintain.
[0049] Optionally, such as Figure 2 As shown, the drive assembly 30 includes a drive member 31 and a balance member 32. The drive member 31 is mounted on the second frame 10; the balance member 32 extends along the first direction and is connected to the output end of the drive member 31. The two ends of the balance member 32 are connected one-to-one with the two ends of the sliding assembly 40. It can be understood that, because the movable roller 20 has a certain length in the first direction, the arrangement of the balance member 32 ensures that both ends of the sliding assembly 40 can receive thrust in the second direction, thus ensuring the synchronicity of the sliding of both ends of the sliding assembly 40.
[0050] Optionally, the driving component 31 is a cylinder, driven by a pneumatic source, which has a more efficient pressure regulation method, can ensure sufficient pressure on the movable roller 20 for a long time, thereby ensuring sufficient and consistent pressure of the movable roller 20 on the transparent paper, and the cost of pneumatic pressure maintenance is low when maintaining pressure for a long time.
[0051] In other embodiments, the drive element 31 may also be a linear drive element such as a linear motor, which is not limited here.
[0052] Optionally, such as Figure 2 As shown, the second frame 10 includes two fixing members 11 and a second connecting member 12. The two fixing members 11 are spaced apart along a first direction, and the two ends of the sliding assembly 40 are slidably engaged with the two fixing members 11 in a one-to-one correspondence. The second connecting member 12 extends along the first direction and connects between the two fixing members 11, and the driving member 31 is mounted on the second connecting member 12. Thus, the space between the two fixing members 11 is used for the installation and sliding of the sliding assembly 40, and the second connecting member 12 is used for the installation of the driving member 31.
[0053] Optionally, in order to further improve the balance of the driving force provided by the drive member 31, the drive member 31 is installed in the middle of the second connector 12 to prevent the drive member 31 from applying force at an angle.
[0054] Optionally, such as Figure 2 and Figure 3 As shown, the sliding assembly 40 includes a first connecting member 42 and two sliding members 41. The two sliding members 41 are slidably engaged with the two ends of the second frame 10 (i.e., the two fixing members 11) in a one-to-one correspondence. Each end of the balancing member 32 is connected to a sliding member 41. The first connecting member 42 is connected between the two sliding members 41, and the two ends of the movable roller 20 are pivotally connected to the first connecting member 42. Thus, the first connecting member 42 and the two sliding members 41 are integrated, improving the overall sliding synchronization of the sliding assembly 40. It can be understood that in the existing configuration, the first connecting member 42 is not provided, but a solid roller is pivotally connected to the two sliding members 41 at both ends. This sliding, which relies solely on the pulling or pushing of the balancing member 32, is prone to poor synchronization when the two sliding members 41 are far apart. In the solution of this embodiment, the movable roller 20 is a hollow roller (see...). Figure 4 When the movable roller 20 rotates, the second connecting piece 12 does not rotate with it, which can better ensure that the entire sliding assembly 40 slides at the same time and ensure that the distance between the two ends of the movable roller 20 and the two ends of the fixed roller is consistent.
[0055] Optionally, see Figures 2-4The movable mechanism also includes two bearings 50, which are spaced apart within the movable roller 20. The outer ring of each bearing 50 is embedded in the movable roller 20, and the inner ring of each bearing 50 is fitted onto the first connecting member 42. By using the bearings 50, the movable roller 20 can rotate relative to the first connecting member 42.
[0056] To achieve a sliding fit between the fixed member 11 and the sliding member 41, such as Figure 2 and Figure 3 As shown, the fixing member 11 has a groove 112 extending along the second direction. The sliding member 41 includes a sliding part 411 and a limiting part 412. The sliding part 411 is located in the groove 112 and slides in cooperation with the groove 112. The limiting part 412 is larger than the groove 112 in the third direction (Z direction in the figure, which is perpendicular to the X and Y directions) and can abut against the fixing member 11. With the above arrangement, the limiting part 412 abuts against the fixing member 11 to prevent the sliding member 41 from moving in the first direction during the sliding process.
[0057] In other embodiments, it can also be a combination of slide rail and slider, which is not limited here.
[0058] Optionally, such as Figures 1-3 As shown, the fastener 11 has a through hole 113 extending in the second direction, and the third connector 60 is provided through the through hole 113 and is connected at both ends to the balancer 32 and the slider 41 (specifically, connected to the slider 411).
[0059] Optionally, such as Figure 2 and Figure 3 As shown, one of the second frame 10 and the balancer 32 is provided with a guide 111, which extends along the second direction. The other one is provided with a guide hole 321 or a guide groove that matches the cross section of the guide 111. The guide 111 can slide in the guide hole 321 or the guide groove. Through the above arrangement, it can be ensured that the balancer 32 moves accurately along the second direction during the movement, avoiding deflection.
[0060] Alternatively, the balancer 32 is arranged in a Z-shape, thereby allowing the drive 31 to be positioned closer to the movable roller 20, thus reducing the overall size of the device in the second direction.
[0061] Optionally, such as Figure 2 As shown, at least two guide members 111 are provided at both ends of the second frame 10, or at least two guide members 111 are provided at both ends of the balance member 32, with the at least two guide members 111 spaced apart in the third direction. This arrangement simultaneously satisfies balance in the third direction.
[0062] Optionally, such as Figure 3 and Figure 4As shown, the movable mechanism also includes a transmission gear 70, which is coaxially fixed to the end of the movable roller 20. The transmission gear 70 is configured to be connected to a power source for transmission. Thus, the movable roller 20 is driven to rotate by external rotation. It should be noted that the connecting end of the transmission gear 70 is inserted into the movable roller 20 and connected to the end face by screws, and there is a gap between the transmission gear 70 and the first connecting member 42. Of course, in other embodiments, the transmission gear 70 can also be provided on the fixed roller; this is not limited here.
[0063] This embodiment also provides a cigarette box packaging device, including the above-mentioned transparent paper clamping and conveying device. By using the above-mentioned transparent paper clamping and conveying device, the transparent paper is pressed in a consistent manner during the conveying process, ensuring the packaging consistency of the cigarette boxes, improving the packaging quality of the cigarette boxes, and having a long service life and being easy to maintain.
[0064] 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 various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments 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.
