Description

Technical Field

[0001] This utility model relates to the field of cigarette manufacturing technology, and in particular to a mold box structure and a cigarette packaging machine. Background Technology

[0002] The ZB45 cigarette packaging machine is a high-speed automated packaging equipment widely used in the cigarette industry. Its main function is to complete a series of actions, including wrapping, transferring, shaping, and boxing the cigarette packs with aluminum foil. In this equipment, the No. 3 and No. 4 roller mold boxes constitute an important transition link for the transfer of the aluminum foil cigarette packs. After the aluminum foil cigarette packs are initially wrapped in the No. 3 roller mold box, they are pushed into the No. 4 roller mold box through the mold box opening for further shaping and positioning. This step has a critical impact on the appearance quality and packaging integrity of the finished cigarettes.

[0003] To ensure accurate positioning of the aluminum foil within the No. 4 mold box, a positioning component is added to the frame-shaped inner cavity of the No. 4 mold box to assist in stabilizing the position of the cigarette paper or aluminum foil during high-speed operation. While this design ensures the positioning accuracy of the aluminum foil, the addition of the positioning component disrupts the overall flatness of the inner cavity of the No. 4 mold box. In the packaging process of slim cigarettes, the overlap of the aluminum foil is relatively large, generally about 4 mm. When the wrapped aluminum foil cigarette pack is subjected to the tension of the paper inside the No. 3 mold box, the overlap may slightly fold outward or spring open. When it passes through the No. 3 mold box and is pushed into the No. 4 mold box, if there is a height difference or gap in the inner wall of the No. 4 mold box, scratches, damage, or even tears can easily occur at the overlap, affecting the appearance quality of the cigarettes and production efficiency. Utility Model Content

[0004] This utility model provides a mold box structure and a cigarette packaging machine that can prevent scratches at the seams and ensure the appearance quality and production efficiency of cigarettes.

[0005] This utility model discloses a mold box structure applied to the fourth wheel assembly of a cigarette packaging machine. The mold box structure includes a rectangular frame and an L-shaped positioning member disposed on one side of the rectangular frame along its length. The rectangular frame includes an adjacent and perpendicular first support arm and a second support arm. The two sides of the L-shaped positioning member correspond to the first support arm and the second support arm, respectively. The first support arm corresponds to the length direction of the rectangular frame. A leveling structure is disposed on the first support arm. One end of the leveling structure is connected to the L-shaped positioning member, and the other end extends to the second support arm. The top surface of the leveling structure is flush with the top surface of the L-shaped positioning member.

[0006] Optionally, the leveling structure is made of alloy steel or aluminum and is integrally formed with the rectangular frame.

[0007] Optionally, the leveling structure is detachably connected to the first support arm.

[0008] Optionally, the leveling structure is connected to the first support arm by welding.

[0009] Optionally, an inwardly protruding limiting protrusion is formed on the second support arm.

[0010] Optionally, a limit stop is formed at the bottom of the rectangular frame.

[0011] Optionally, the limiting block is located on the first support arm, and / or the limiting block is located at the connection between the first support arm and the second support arm.

[0012] Optionally, the limiting block is rectangular or triangular.

[0013] Optionally, a connecting portion is provided on the outer side of one of the first support arms, the connecting portion being used to connect with the fourth wheel set.

[0014] This utility model also discloses a cigarette packaging machine, including the mold structure described in any one of the above.

[0015] The beneficial effects of the mold box structure and cigarette packaging machine provided by this utility model embodiment are as follows: By setting a leveling structure on the first support arm, one end of the leveling structure is connected to the L-shaped positioning part, and the other end extends to the second support arm. The top surface of the leveling structure is flush with the top surface of the L-shaped positioning part, thus realizing the overall planarization of the inner cavity of the mold box structure. When the aluminum foil cigarette pack is handed over between the No. 3 wheel mold box and the mold box structure applied to the No. 4 wheel pack, the aluminum foil paper overlap can maintain parallel contact with the inner wall of the rectangular frame. This avoids the aluminum foil paper overlap being snagged, scratched, or broken due to insufficient height of the original gap and the non-planar structure. This achieves a stable transition and complete packaging of the cigarette aluminum foil paper pack, thereby significantly improving the appearance quality of the cigarette, reducing production consumption, reducing maintenance frequency, and improving production efficiency.

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0019] like Figure 1 and Figure 2 As shown, this utility model embodiment provides a mold box structure 100, which is applied to the fourth wheel set of a cigarette packaging machine. The mold box structure 100 includes: a rectangular frame 110, and an L-shaped positioning member 120 provided on one side of the rectangular frame 110 along its length. The rectangular frame 110 includes an adjacent and perpendicular first support arm 112 and a second support arm 114. The two sides of the L-shaped positioning member 120 correspond to the first support arm 112 and the second support arm 114, respectively. The first support arm 112 corresponds to the length direction of the rectangular frame 110. A leveling structure 130 is provided on the first support arm 112. One end of the leveling structure 130 is connected to the L-shaped positioning member 120, and the other end extends to the second support arm 114. The top surface of the leveling structure 130 is flush with the top surface of the L-shaped positioning member 120.

[0020] Specifically, the L-shaped positioning member 120 is disposed on one side of the rectangular frame 110 along its length, with its two sides respectively connected to the first support arm 112 and the second support arm 114, forming a structure similar to "corner positioning." This ensures that the aluminum foil cigarette assembly can maintain a stable position during high-speed operation, preventing lateral or longitudinal displacement. Additionally, one end of the leveling structure 130 is connected to the L-shaped positioning member 120, and the other end extends to the second support arm 114. The top surface of the leveling structure 130 is flush with the top surface of the L-shaped positioning member 120. The length of the leveling structure 130 covers the area from the L-shaped positioning member 120 to the second support arm 114, preventing the leveling structure 130 from causing new interference to the rectangular frame 110. Furthermore, the inner side of the leveling structure 130 is flush with the inner side of the first support arm 112, and its thickness is designed to ensure a flush top surface. This ensures that there is no height difference in the support surface of the entire mold box structure 100 cavity and guarantees the smoothness of the sliding path of the aluminum foil cigarette assembly.

[0021] The mold box structure 100 provided in this application embodiment achieves overall planarization of the inner cavity of the mold box structure 100 by means of a leveling structure 130 provided on the first support arm 112. One end of the leveling structure 130 is connected to the L-shaped positioning member 120, and the other end extends to the second support arm 114. The top surface of the leveling structure 130 is flush with the top surface of the L-shaped positioning member 120. This enables the aluminum foil paper cigarette pack assembly to maintain parallel contact with the inner wall of the rectangular frame 110 when it is handed over between the No. 3 wheel mold box and the mold box structure 100 applied to the No. 4 wheel assembly. This avoids the aluminum foil paper overlap from being snagged, scratched, or broken due to insufficient height of the original gap and non-planar structure. As a result, a stable transition and complete packaging of the cigarette aluminum foil paper pack assembly are achieved, which significantly improves the appearance quality of the cigarette, reduces production consumption, reduces maintenance frequency, and improves production efficiency.

[0022] In an optional embodiment of this application, the leveling structure 130 is made of alloy steel or aluminum and is integrally formed with the rectangular frame 110.

[0023] Specifically, alloy steel features high strength, high hardness, and good wear resistance, enabling it to withstand the impact and friction forces during high-speed transfer of aluminum foil cigarette sets. It also possesses good toughness, making it less prone to deformation or breakage. Aluminum, on the other hand, offers advantages such as light weight, corrosion resistance, and good machinability, reducing the overall weight of the mold box and lowering the operating load of the No. 4 wheel set. Furthermore, the surface flatness of aluminum is easily controlled, making it suitable for structural components requiring high-precision flat surfaces. The one-piece machining process ensures that there are no connection gaps between the leveling structure 130 and the rectangular frame 110, while also enhancing the connection strength between them, preventing the leveling structure 130 from detaching or shifting due to long-term use or high-speed impact.

[0024] In an optional embodiment of this application, the leveling structure 130 is detachably connected to the first support arm 112.

[0025] Specifically, compared to integral molding, the detachable leveling structure 130 and the first support arm 112 can be machined separately, reducing the machining difficulty and equipment requirements of individual components. In practical applications, matching threaded holes can be provided on the leveling structure 130 and the first support arm 112 to facilitate connection by bolts or screws. The detachable connection allows the leveling structure 130 to be disassembled and replaced individually without replacing the entire rectangular frame 110, significantly reducing equipment maintenance costs.

[0026] In an optional embodiment of this application, the leveling structure 130 is connected to the first support arm 112 by welding.

[0027] Specifically, the metallurgical bond formed by the welding connection makes the leveling structure 130 and the first support arm 112 a whole. The connection strength is much higher than that of detachable connections and ordinary splicing structures. It can withstand the impact, friction and vibration loads when the aluminum foil cigarette sticks are transferred at high speed, and avoid the failure of the mold box structure 100 due to loosening or falling off of the connection, thus ensuring the stability and reliability of the equipment in high-speed automated production.

[0028] like Figure 1 As shown, an inwardly protruding limiting protrusion 1142 is formed on the second support arm 114.

[0029] Specifically, during the process of pushing the aluminum foil cigarette assembly from the No. 3 wheel mold box into the mold box structure 100 of this application, high-speed movement may cause the aluminum foil cigarette assembly to shift laterally, affecting the subsequent forming and boxing accuracy. The limiting protrusion 1142 on the second support arm 114 can block and limit the aluminum foil cigarette assembly laterally, ensuring the accurate lateral position of the aluminum foil cigarette assembly within the mold box structure 100, avoiding uneven aluminum foil wrapping or boxing difficulties due to shifting, and further improving the accuracy and consistency of cigarette packaging.

[0030] like Figure 1 As shown, a limit stop 140 is formed at the bottom of the rectangular frame 110.

[0031] Specifically, the limiting block 140 can support the aluminum foil cigarette pack inside the mold box structure 100 to prevent the aluminum foil cigarette pack from detaching from the rectangular frame 110, which helps to ensure the stability of production.

[0032] In optional embodiments of this application, such as Figure 1 As shown, the limiting block 140 is located on the first support arm 112, and / or the limiting block 140 is located at the connection between the first support arm 112 and the second support arm 114.

[0033] Specifically, the limiting blocks 140 only need to support the aluminum foil cigarette pack. The more limiting blocks 140 are set in a certain position and the more evenly they are distributed within the rectangular frame 110, the better the supporting effect on the aluminum foil cigarette pack will be. This will prevent the aluminum foil cigarette pack from becoming skewed and help ensure the packaging quality.

[0034] In an optional embodiment of this application, the limiting block 140 is rectangular or triangular. The triangular limiting block 140 is characterized by its small size and minimal space occupation, making it easy to install at corner positions. The rectangular limiting block 140 is characterized by its flat contact surface, uniform force distribution, and large contact area with the end of the cigarette assembly, providing a stable limiting force to ensure the limiting effect.

[0035] like Figure 1As shown, a connecting part 1122 is provided on the outer side of one of the first support arms 112, and the connecting part 1122 is used to connect with the fourth wheel set.

[0036] Specifically, the connection part 1122 facilitates the connection between the mold box structure 100 and the No. 4 wheel set, ensuring that the mold box structure 100 is firmly fixed during high-speed rotation, avoiding loosening, vibration or falling off, and ensuring the high-speed operation stability of the equipment.

[0037] This utility model also discloses a cigarette packaging machine, including the mold structure 100 in the foregoing embodiments. This cigarette packaging machine has the same structure and beneficial effects as the mold structure 100 in the foregoing embodiments. The structure and beneficial effects of the mold structure 100 have been described in detail in the foregoing embodiments and will not be repeated here.

[0038] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
