[0031] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0032] In the description of the present application, unless explicitly specified and limited, the terms "connected", "connected", "fixed" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0033] In the present application, unless explicitly specified and limited, the first feature "on" or "under" the second feature can include that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, the first feature "on", "above" and "above" the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature "below", "below" and "below" the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.

[0034] In the description of the present embodiment, the terms "up", "down", "left", "right", and other orientation or position relationships are based on the orientation or position relationship shown in the drawings, and are only for the convenience of description and simplification of operation, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0035] Reference Figures 1-7 , embodiment 1 provides a cigarette package forming wheel, which comprises two opposite wheel bodies 1, each wheel body 1 comprises a plurality of box molds 2, and the box molds 2 of the two wheel bodies 1 form a space for longitudinally accommodating a cigarette package 100 two by two. The bottoms of all the box molds 2 on one wheel body 1 include avoidance grooves 3 for avoiding the corresponding side edges of the hard-box cigarette package 100 near the side edges of the slotted large face of the hard-box cigarette package 100. The outer sides of the two wheel bodies 1 further include guide plates 4 for guiding and limiting the cigarette package 100 in the box molds 2.

[0036] Reference Figure 9 , the applicant finds that the position of the frame paper 101 most prone to creases in the hard box cigarette packet 100 is the frame paper ear 102 for producing a damping effect during the opening process of the cigarette packet 100, such as the frame paper crease 103. When the cigarette packet 100 moves quickly into the box die 2, the top end of the cigarette packet 100 will impact the bottom of the box die 2, and the frame paper ear 102 located at the edge position directly bears the impact, so it is prone to creases. The frame paper ear 102 is located on the opening seam large surface of the hard box cigarette packet 100 and the inner side of the cover body.

[0037] The avoidance groove 3 is provided on the side corresponding to the opening seam large surface of the hard box cigarette packet 100 on the box die 2, which can avoid the impact force of the bottom of the box die 2 on the frame paper ear 102 of the cigarette packet 100, and reduce the probability of creases. The avoidance groove 3 has little change to the existing wheel body, and does not affect the forming wheel for producing other types of cigarette packets 100. The cigarette packet packaging forming wheel of the present application can reduce the creases at the frame paper ear 102, and improve the production efficiency of the hard box cigarette packet containing the frame paper 101.

[0038] In some embodiments of the present disclosure, the width of the avoidance groove 3 is 2-5 mm. The width that is too wide will cause the area of the bottom of the box die 2 for contacting the end surface of the cigarette packet 100 to be too small, so that the whole cigarette packet 100 and the internal cigarettes are prone to quality problems such as wrinkles, and the width that is too narrow cannot avoid the frame paper ear 102. In the specific embodiment, the width of the avoidance groove 3 is 5 mm.

[0039] In some embodiments of the present disclosure, the depth of the avoidance groove 3 is not less than 1 mm. The depth that is too small will cause the space for the deformation buffer of the cigarette packet 100 to be insufficient, and the avoidance effect on the frame paper ear 102 is insufficient, and the depth that is too large will increase the difficulty of implementing the avoidance groove 3. In the specific embodiment, the depth of the avoidance groove 3 is 1 mm.

[0040] Reference Figures 2-3 The avoidance groove 3 can be implemented in various ways, for example, the avoidance groove 3 can be directly milled on the existing forming wheel body box die, or a block body capable of forming the avoidance groove 3 together with the box die can be additionally installed. In the present embodiment, the bottom of the box die 2 includes a buffer block 5, and the side surface of the buffer block 5 forms one side wall of the avoidance groove 3. Implementing the avoidance groove 3 with the buffer block 5 can balance the additional impact caused by the reduction of the contact area between the end of the cigarette packet 100 and the bottom of the box die, and reduce the occurrence of other quality accidents.

[0041] The buffer block 5 can be implemented in various ways, as long as it has a buffer and energy absorption effect, for example, it can be set as a rubber block. Reference Figures 4-5In the embodiment, the buffer block 5 comprises a resilient member 51 directed towards the cigarette packet 100, and a fixing member 53 and a contact member 52 connected to both ends of the resilient member 51, the fixing member 53 is fixed to the wheel body 1 by screwing, and the contact member 52 is close to the direction of the cigarette packet 100. The resilient member 51, such as a spring, is arranged in the buffer block 5, so that the buffer block 5 has better buffering and energy absorption effect and higher durability.

[0042] Reference Figure 6 In the embodiment, the guide plate 4 is detachably connected to the wheel body 1, and the inner side of the guide plate 4 is provided with a guide portion 41 for guiding the buffer block 5, so as to improve the movement accuracy of the contact member after bearing the impact and avoid the cigarette packet 100 being clamped and damaged by skewing. Specifically, the guide portion 41 is a guide rail, and the contact member 52 comprises a guide block 54 which can slide in the guide rail.

[0043] In the embodiment, the buffer block 5 comprises rubber, and specifically, the contact member 52 is composed of rubber, which can buffer and absorb energy by itself through deformation.

[0044] In the embodiment, the two wheel bodies 1 are respectively a first wheel body 11 and a second wheel body 12, wherein Figure 2 The bottom of all the box molds 2 on the first wheel body 11 is close to the side edge of the hard box cigarette packet 100, and comprises an avoiding groove 3 for avoiding the corresponding side edge of the cigarette packet 100. Figure 7 The bottom of the box mold 2 on the second wheel body 12 is a plane. In most existing packaging machines, the push rod assembly 200 does not contact the center of the end surface of the cigarette packet 100 when pushing the packet, so the impact of the wheel body 1 on one side on the cigarette packet 100 is greater, and the crease of the frame paper ear 102 also mainly appears on the wheel body on one side. Therefore, only arranging the avoiding groove 3 on one of the wheel bodies can reduce the changes to the forming wheel, and is sufficient to improve the probability of the appearance of the frame paper crease 103. In other embodiments, the avoiding grooves 3 can be arranged on both wheel bodies 1 to avoid the frame paper ears 102 on both sides.

[0045] Reference Figure 8 The cigarette packet 100 packaging forming wheel and the push rod assembly 200 for pushing the cigarette packet 100 into the box mold 2 of the packaging machine provided in Embodiment 2 have all the beneficial effects of Embodiment 1. Compared with the existing packaging machine, the cigarette packet 100 packaging forming wheel of the present application can allow the push rod assembly 200 to push the packet at a faster speed without generating the frame paper crease 103, thereby improving the production efficiency.

[0046] In the embodiment, the box mould 2 of the wheel body 1 relatively close to the push rod assembly 200 comprises an avoiding groove 3, and the bottom of the box mould 2 of the second wheel body 12 is flat. In the embodiment and most of the existing packaging machines, such as the YB55 type packaging machine, the push rod assembly 200 pushes the packet at the position relatively close to the outer side of the packaging machine at the end surface of the cigarette packet 100, so that the impact of the wheel body 1 close to the outer side on the cigarette packet 100 is greater, and the crease of the frame paper ear 102 also mainly appears on the wheel body on the outer side. In the embodiment, the first wheel body 11 is installed close to the outer side, and the second wheel body 12 is installed close to the inner side.

[0047] In the embodiment, the fixed folding part 301 is arranged along the movement track of the end surface of the cigarette packet 100 away from the center of the wheel body 1, and the movable folding part 302 is arranged in front of the fixed folding part 301 along the movement track of the cigarette packet 100 and can move towards or away from the fixed folding part 301, and when moving towards the fixed folding part 301, the transparent paper is folded along the movement direction. Compared with the existing packaging machine, after the cigarette packet 100 packaging forming wheel of the application is implemented, the cigarette packet 100 can be conveyed at a faster speed, and the fixed folding part 301 and the movable folding part 302 can process the folding of the transparent paper at a faster speed.
