Description

Technical Field

[0001] The utility model belongs to the technical field of cigarette packing machinery and equipment, and particularly relates to an asymmetric cigarette pack conveying device for a GDX1 packing machine. Background Art

[0002] The GDX1 cigarette packaging machine is a relatively advanced and mature packaging machine. It demonstrates excellent stability and product packaging quality during production. It is a workhorse model and plays a key role in cigarette packaging production. During transportation, cigarettes drop from the cigarette storage onto the cigarette squeezer's mold box. A push rod forces them into the cigarette box, arranging 20 cigarettes in a 7-6-7 arrangement. Driven by synchronous pulleys and belts, the cigarette box conveys the cigarettes from the storage to wheel number one, which then transfers them to wheel number two, and so on, until wheel number four. A push rod pushes the cigarette packs out of the fourth wheel for the next process step. Inspection of the cigarettes within the packed packs revealed that compared to other models, the GDX1's cigarettes were significantly deformed, significantly affecting their appearance.

[0003] In order to solve the above problems, the present invention is proposed. Utility Model Content

[0004] This applicant measured the cigarette pack slots of the cigarette mold box, wheels 1, 2, 3, and 4, and found that the dimensions of the cigarette pack slots in all the conveyor wheel systems did not meet the requirements of current production specifications. This was the key reason for the small and deformed cigarettes after packaging. The only solution to this problem was to appropriately change the cigarette pack slot dimensions.

[0005] However, the current model uses a symmetrical conveying method to transport cigarette packs. The so-called symmetrical conveying method means that when the cigarette packs are transported from the cigarette squeezer to the fourth wheel, the cigarette packs are always on the same axis when transported between the two adjacent wheels (such as Figure 2 Due to the structure of the cigarette mold box, the second wheel, the third wheel, and the fourth wheel, it is not feasible to modify the equipment based on the symmetrical conveying method. This would result in huge modification costs and even require the complete replacement of the existing equipment.

[0006] In order to solve this problem, the present invention provides an asymmetric cigarette pack conveying device and method for a GDX1 packaging machine.

[0007] In a first aspect, the present application provides an asymmetric cigarette pack conveying device for a GDX1 packaging machine, the asymmetric cigarette pack conveying device comprising: a cigarette squeezer, a first wheel, a second wheel, a third wheel, and a fourth wheel arranged in sequence from upstream to downstream, wherein the central axes of the first wheel, the second wheel, the third wheel, and the fourth wheel are located on the same straight line;

[0008] The cigarette squeezer comprises: a mold box synchronous belt, a cigarette squeezer mold box is arranged on the mold box synchronous belt, and the cigarette squeezer mold box has a bottom plate and a cover plate, and the cover plate is detachably connected to the bottom plate by studs so that the height of the cover plate can be adjusted to change the height of the cavity in the cigarette squeezer mold box;

[0009] The number one wheel has a cigarette clamping claw inside, and the cigarette clamping claw is configured to be able to adjust the height of its clamping cavity;

[0010] The second wheel, the third wheel and the fourth wheel are all circumferentially provided with grooves, and cigarette holder mold boxes are detachably arranged in the grooves;

[0011] The bottom of the cigarette holder mold box is mounted on the bottom of the groove by screws, and the screws of each groove are symmetrically distributed along the center of the wheel, and the screws are located at non-central axis positions of the cavity of the cigarette holder mold box;

[0012] The height of the cavity in the cigarette mold box is configured to be equal to the height of the cavity in the cigarette squeezer mold box.

[0013] The bottom mentioned above refers to a position close to the central axis of the wheel.

[0014] Preferably, the number one wheel is configured to rotate counterclockwise, and the number one wheel is configured such that the central axis of the clamping cavity at the intersection of the number one wheel and the cigarette squeezer is located above the central axis of the number one wheel.

[0015] Preferably, the number two wheel is configured to rotate clockwise, and the center axis of the cavity of the cigarette holder mold box at the intersection of the number two wheel and the number one wheel is located below the center axis of the number two wheel.

[0016] Preferably, the third wheel is configured to rotate counterclockwise, and the central axis of the cavity of the cigarette holder mold box at the intersection of the third wheel and the second wheel is located above the central axis of the third wheel.

[0017] Preferably, the fourth wheel is configured to rotate clockwise, and the central axis of the cavity of the cigarette holder mold box at the intersection of the fourth wheel and the third wheel is located below the central axis of the third wheel.

[0018] Preferably, the mold boxes on the second wheel, the third wheel and the fourth wheel have various specifications.

[0019] A second aspect of the present application provides an asymmetric cigarette packet conveying method for a GDX1 packaging machine, wherein the asymmetric cigarette packet conveying method is performed using the asymmetric cigarette packet conveying device according to any one of the first aspects;

[0020] The asymmetric cigarette packet conveying method comprises the following steps:

[0021] Step A: The cigarette group is loaded into the cavity of the cigarette squeezer mold box and moves along with the mold box synchronous belt, the first wheel rotates counterclockwise, the second wheel rotates clockwise, the third wheel rotates counterclockwise, and the fourth wheel rotates clockwise;

[0022] Step B: When the cigarette group moves to the intersection of the cigarette squeezer mold box and the number one wheel, the cigarette group is transferred from the cigarette squeezer mold box to the clamping cavity of the cigarette clamping claw of the number one wheel at the intersection; and the central axis of the clamping cavity of the cigarette clamping claw of the number one wheel at the intersection is located above the central axis of the number one wheel;

[0023] Step C: When the cigarette group moves to the intersection of the number one wheel and the number two wheel, the cigarette group is transferred from the clamping cavity of the cigarette clamping claw of the number one wheel to the cavity of the cigarette mold box of the number two wheel at the intersection; and the central axis of the cavity of the cigarette mold box of the number two wheel at the intersection is located below the central axis of the number two wheel;

[0024] Step D: When the cigarette group moves to the intersection of the second wheel and the third wheel, the cigarette group is transferred from the cavity of the cigarette mold box of the second wheel to the cavity of the cigarette mold box of the third wheel at the intersection; and the central axis of the cavity of the cigarette mold box of the third wheel at the intersection is located above the central axis of the third wheel;

[0025] Step E: When the cigarette group moves to the intersection of the third wheel and the fourth wheel, the cigarette group is transferred from the cavity of the cigarette mold box of the third wheel to the cavity of the cigarette mold box of the fourth wheel at the intersection; and the central axis of the cavity of the cigarette mold box of the fourth wheel at the intersection is located below the central axis of the fourth wheel.

[0026] In this article, the cavity inside the cigarette squeezer mold box, the clamping cavity of the cigarette clamping claws of the No. 1 wheel, and the cavity of the cigarette mold box can all be called cigarette pack slots.

[0027] Compared with the prior art, this application has the following beneficial effects:

[0028] 1. Prior art uses symmetrical cigarette pack conveying devices. During the process of conveying cigarette packs from the cigarette squeezer to the fourth wheel, the cigarette packs are always on the same axis when conveyed between two adjacent wheels, thus achieving successful transfer of cigarette packs between the two adjacent wheels. Prior art has never paid attention to asymmetrical cigarette pack conveying devices. In fact, it is generally believed that asymmetrical conveying devices are difficult to design and cannot achieve successful transfer of cigarette packs between the two adjacent wheels because the cigarette packs are not on the same axis when conveyed between the two adjacent wheels.

[0029] This application only makes some changes to the GDX1 cigarette packaging machine, for example:

[0030] The cover plate of the cigarette squeezer mold box is detachably connected to the base plate via a stud. The threads on the two ends of the stud are opposite, one left-handed and the other right-handed. The threaded holes in the base plate are left-handed, while those in the cover plate are right-handed. The center of the stud has two flattened surfaces milled flat to facilitate later adjustment with a wrench. This allows the height of the cover plate to be easily adjusted using the stud, thereby varying the height of the cavity within the cigarette squeezer mold box.

[0031] The height of the cigarette mold box cavity is adjusted only by adjusting the position of the bottom plate of the cigarette mold box without changing the screw installation position between the cigarette mold box and the groove, resulting in the screw being offset from the central axis position of the cigarette mold box cavity to a non-central axis position;

[0032] The above two solutions achieve a larger height of the cigarette pack slot in the entire conveying device. Therefore, this application effectively solves the problem of cigarette and cigarette box deformation caused by the original mold box structure.

[0033] 2. In addition, the new mold box structure can improve the mold box size according to actual needs, and has good compatibility for the production of cigarettes of different specifications.

[0034] 3. In addition, the detachable mold box fixed with screws on the second wheel, the third wheel and the fourth wheel has a simple structure, convenient operation and simple maintenance.

[0035] 4. In summary, the standard mold box provided by this application effectively adapts to the production of cigarette packs of different specifications. This application avoids quality problems such as cigarette deformation and cigarette pack deformation, and effectively improves the packaging quality of the packaging machine.

[0054] In response to the problems existing in the background technology, the present application proposes an asymmetric cigarette pack conveying device and method for a GDX1 packaging machine. In view of the symmetrical conveying mode between the four packaging wheels, the structure of the cigarette mold box 8 of the second and third wheels is improved. By changing the structure of the cigarette mold box 8, an asymmetric conveying mode is formed. After the structure of the cigarette mold box 8 is improved, the size of the cigarette mold box 8 is no longer restricted by the original conveying mode, and the size of the mold box can be adjusted according to actual needs to avoid cigarette pack squeezing and cigarette squeezing during the packaging process.

[0062] The height of the cavity inside the cigarette mold box 8 is configured to be equal to the height of the cavity inside the cigarette squeezer mold box 1 - 1 .

[0063] Preferably, the number one wheel 2 is configured to rotate counterclockwise, and the number one wheel 2 is configured such that the central axis of the clamping cavity at the intersection of the number one wheel 2 and the cigarette squeezer 1 is located above the central axis of the number one wheel 2 .

[0064] Preferably, the number two wheel 3 is configured to rotate clockwise, and the center axis of the cavity of the cigarette holder mold box 8 at the intersection of the number two wheel 3 and the number one wheel 2 is located below the center axis of the number two wheel 3 .

[0066] Preferably, the fourth wheel 5 is configured to rotate clockwise, and the central axis of the cavity of the cigarette holder mold box 8 at the intersection of the fourth wheel 5 and the third wheel 4 is located below the central axis of the third wheel 4.

[0067] Preferably, the cigarette holder mold boxes 8 on the second wheel 3, the third wheel 4 and the fourth wheel 5 have various specifications.

[0068] The asymmetric cigarette packet conveying method of the present application comprises the following steps:

[0069] Step A: The cigarette group is loaded into the inner cavity of the cigarette squeezer mold box 1-1 and moves along with the mold box timing belt 1-2. The first wheel 2 rotates counterclockwise, the second wheel 3 rotates clockwise, the third wheel 4 rotates counterclockwise, and the fourth wheel 5 rotates clockwise.

This application improves the cigarette squeezer mold box 1-1, featuring a removable cover plate 1-1-2 connected to the base plate 1-1-1 by four studs 1-1-3. Because the upper and lower threads of the studs 1-1-3 rotate in opposite directions, the height of the cigarette squeezer mold box 1-1 can be adjusted by rotating the four studs 1-1-3.

[0075] The cigarette mold boxes 8 of the second wheel 3, the third wheel 4 and the fourth wheel 5 have been improved. The cigarette mold boxes 8 on their workstations are all detachable and can be removed and replaced individually. At the same time, the fixed size of the cigarette mold box 8 is changed to a movable mold box by moving the mold box bottom plate, so that the size of the cigarette mold box 8 can be changed arbitrarily. Figure 5 This is a schematic diagram of the No. 2 wheel structure of this application.

[0076] Furthermore, the cigarette pack molds 8 of the second, third, and fourth wheels can be modified into detachable standardized molds. This allows the mold sizes of the fourth and third wheels to change with those of the second wheel, thus forming an asymmetric cigarette pack conveying method. The molds are fixed with screws for easy removal and replacement. Figure 6 This is a schematic diagram of the structure of the third wheel of this application.
