Description

Technical Field

[0001] This utility model relates to the field of cigarette stacking technology, and in particular to a cigarette stacking mechanism. Background Technology

[0002] In the automatic cigarette sorting line, the sorted cigarettes need to be stacked by a stacking device before being plastic-sealed.

[0003] Existing stacking devices, such as the solution disclosed in patent CN201276358Y, include stacking wheels, a drive device, a bracket, side baffles, positioning baffles, and sensors. The blades of the stacking wheels are fixedly mounted on a spindle. However, the lateral spacing between the blades of the two stacking wheels in this device is fixed and cannot be adjusted. When processing short cigarette packs, because the blade spacing is greater than the length of the cigarette pack, the cigarette packs easily leak out through the gaps, making effective stacking impossible and limiting its applicability to short cigarette packs. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a cigarette stacking mechanism.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a cigarette stacking mechanism, including a stacking wheel, a driving device, a frame, a cigarette side baffle, a cigarette positioning baffle, and a sensor. There are two stacking wheels, which are symmetrically arranged on the bearing seats of the frame and connected to the driving device. The stacking wheel includes a stacking core shaft and a plurality of stacking plates evenly distributed along the circumference of the stacking core shaft. A movable groove is provided at the end of the stacking plate away from the stacking core shaft. An extension plate is slidably embedded in the movable groove. A locking member for locking the extension plate is provided on the stacking plate.

[0006] Furthermore, the stacking plate has a support surface for supporting the cigarette packs, and the end face of the stacking plate opposite to the support surface is a guide surface. The guide surface is provided with an elongated waist-shaped hole arranged along the moving direction of the extension plate, and the lower end of the extension plate is provided with a guide post extending into the elongated waist-shaped hole. The guide post and the elongated waist-shaped hole are slidably engaged.

[0007] Furthermore, the guide surface is provided with limiting bolts for locking the extension plate.

[0008] Furthermore, the guide surface is provided with a weight-reduction notch that communicates with the movable groove.

[0009] Furthermore, the stacking plate has a retaining plate at one end facing the stacking core shaft, and two limiting plates are provided opposite each other along its axial direction on the outer wall of the stacking core shaft. The limiting plates have slots for inserting and cooperating with the retaining plates, and the outer wall of the limiting plates is also provided with fixing bolts for fixing the retaining plates. The retaining plates have threaded holes that cooperate with the fixing bolts.

[0010] Furthermore, the locking element is a locking screw.

[0011] Furthermore, the extension plate is made of rubber material.

[0012] Furthermore, the thickness of the card plate is less than the thickness of the stacking plate.

[0013] Furthermore, the stacking core shaft is provided with a rotating shaft at both ends, and the rotating shaft is mounted on the bearing seat of the frame.

[0014] The beneficial effects of this application are as follows: 1. By setting a slidable extension plate and its locking device at the end of the stacking plate, this application realizes the adjustment of the effective support distance between the corresponding stacking plates on two symmetrical stacking wheels. When processing short cigarette packs, the actual working distance between the stacking plates on both sides can be reduced by sliding the extension plate to make it smaller than the length of the short cigarette pack, thereby completely avoiding the phenomenon of cigarette packs leaking out from the gap. This allows the device to stably and reliably stack cigarette packs of different lengths (especially short ones), significantly expanding the applicability of the device.

[0015] 2. The sliding fit between the guide post and the elongated hole in this application provides precise guidance for the movement of the extension plate, preventing it from shaking or shifting during operation, ensuring the stability and positioning accuracy of the spacing adjustment, and thus ensuring the reliability of the stacking action.

[0016] 3. The weight-reducing notch design in this application reduces the overall weight of the stacking plate while ensuring structural strength, which helps to reduce the load on the drive device.

[0017] 4. The extension plate of this application is made of rubber material, which can reduce the impact and damage to the cigarette pack packaging.

[0018] 5. The design of this application, in which the card plate and the limiting plate are inserted and fixed by fixing bolts, realizes a modular and detachable connection between the stacking plate and the stacking spindle. This allows individual stacking plates to be replaced or repaired independently and conveniently after wear or damage, without having to replace the entire stacking wheel or spindle, significantly reducing maintenance costs.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, 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, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] Please see Figure 1-8 This utility model provides a cigarette stacking mechanism, including stacking wheels, a drive device, a frame 1, cigarette side baffles, cigarette positioning baffles, and sensors. Two stacking wheels are symmetrically arranged on bearing seats of the frame 1 and connected to the drive device. Each stacking wheel includes a stacking core shaft 2 and multiple stacking plates 3 evenly distributed along the circumference of the stacking core shaft 2 on its outer wall. A movable groove 35 is provided at the end of each stacking plate 3 away from the stacking core shaft 2, and an extension plate 4 is slidably embedded within the movable groove 35. A locking element 31 for locking the extension plate 4 is provided on each stacking plate 3. The locking element 31 is a locking screw. By setting the locking element 31, the position of the extension plate 4 can be quickly and firmly locked after adjustment, preventing it from moving due to force during stacking. It also facilitates flexible and timely adjustment of the spacing according to production needs, making operation convenient.

[0030] The number of stacking tobacco plates 3 is 2-5, preferably three. Each stacking tobacco plate 3 has a support surface 32 for supporting the tobacco strips, and a guide surface 33 on the end face of the stacking tobacco plate 3 facing away from the support surface 32. The guide surface 33 has a weight-reducing notch 34 communicating with the moving groove 35. The weight-reducing notch 34 in this application reduces the overall weight of the stacking tobacco plate while ensuring structural strength, which helps to reduce the load on the driving device. It should be noted that any parts not detailed in this application are prior art.

[0031] Specifically, the end of the stacking plate 3 facing the stacking core shaft 2 is provided with a retaining plate 6. Two limiting plates 5 are provided axially opposite each other on the outer wall of the stacking core shaft 2. The limiting plates 5 have slots for inserting and engaging with the retaining plates 6. The outer wall of the limiting plates 5 also has fixing bolts 51 for securing the retaining plates 6, and the retaining plates 6 have threaded holes for engaging with the fixing bolts 51. Through the design of the retaining plates 6 and limiting plates 5 inserting and engaging and being secured by the fixing bolts 51, a modular and detachable connection between the stacking plate 3 and the stacking core shaft 2 is achieved. This allows a single stacking plate 3 to be replaced or repaired independently and conveniently after wear or damage, without having to replace the entire stacking wheel or stacking core shaft 2, significantly reducing maintenance costs and downtime.

[0032] In addition, the extension plate 4 is made of rubber material, which reduces impact and damage to the cigarette pack. The thickness of the card plate 6 is less than the thickness of the stacking plate 3. The stacking core shaft 2 has a rotating shaft 21 at each end, and the rotating shaft 21 is rotatably mounted on the bearing seat of the frame 1.

[0033] Of course, this utility model is not limited to the embodiments described above. Several other embodiments based on the design concept of this utility model are also provided below.

[0034] For example, in other embodiments, unlike the embodiments described above, such as... Figure 5 As shown. The guide surface 33 has an elongated, waist-shaped hole 331 positioned along the moving direction of the extension plate 4. The lower end of the extension plate 4 has a guide post 41 extending into the elongated, waist-shaped hole 331, with the guide post 41 slidingly engaged with the elongated, waist-shaped hole 331. The guide surface 33 also has a limiting bolt 36 for locking the extension plate 4. The sliding engagement between the guide post 41 and the elongated, waist-shaped hole 331 provides precise guidance for the movement of the extension plate 4, preventing it from shaking or shifting during operation, ensuring the stability and positioning accuracy of the spacing adjustment, and thus ensuring the reliability of the stacking operation.

[0035] For example, in other embodiments, unlike the embodiments described above, in this embodiment, scale lines are provided on both sides of the extension plate 4 to facilitate adjustment of the extension length of the extension plate 4.

[0036] Depending on the length of the cigarette packs to be processed, especially short cigarettes, during adjustment, loosen the locking piece 31 and manually slide the extension plate 4 to extend or retract within the moving groove 35. The guide post 41 at the lower end of the extension plate 4 slides along the oblong hole 331 of the stacked cigarette plate 3 to ensure precise movement trajectory without deviation.

[0037] After adjusting to the target position, ensure that the distance between the extension plates 4 on both sides of the cigarette stacking wheel is less than the length of the cigarette strip, tighten the locking piece 31, and fix the extension plates 4.

[0038] By providing a sliding extension plate 4 and its locking element 31 at the end of the stacking plate 3, the effective support distance between the corresponding stacking plates 3 on the two symmetrical stacking wheels can be continuously adjusted. When processing short cigarette packs, the actual working distance between the stacking plates 3 on both sides can be reduced by sliding the extension plate 4 to make it smaller than the length of the short cigarette pack, thereby completely preventing the cigarette packs from leaking out of the gap. This allows the device to stably and reliably stack cigarette packs of different lengths (especially short ones), significantly expanding the applicability of the device.

[0039] When stacking cigarette packs, the stacking plates 3 or extension plates 4 on both sides of the stacking wheels form a rectangular receiving groove. The cigarette packs are transported laterally along the conveyor belt into the receiving groove and arranged in a row along the stacking core shaft 2. Currently, cigarette packs are generally packaged in layers of 5. When 5 packs are full, a sensor sends a control signal to control the stacking wheels to rotate downwards by 120°, causing the cigarette packs to fall. At the same time, the next stacking plate moves into a horizontal position, forming a rectangular receiving groove again to receive the next batch of cigarette packs. When the second row of cigarette packs is full, the sensor sends a control signal to control the stacking wheels to rotate another 120°. As the stacking wheels rotate, the second row of cigarette packs falls on top of the first row. The above steps are repeated until the required number of layers are stacked.

[0040] It should be noted that the above embodiments are only used to illustrate the present utility model, but the present utility model is not limited to the above embodiments. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
