Description

Technical Field

[0001] This utility model relates to the field of tobacco processing technology, and in particular to a cigarette pack braking mechanism and a cigarette pack packaging machine. Background Technology

[0002] Cigarette packaging machines often receive a large number of rows of cigarette packs as they enter downstream machines. The downstream machines then need to repackage the cigarette packs into groups. During the re-transmission of a certain number of grouped cigarette packs, subsequent cigarette packs must be stopped in a timely manner.

[0003] Existing packaging machines typically have multiple airbags on one side of the conveyor belt. During cigarette pack transport, the airbags inflate and rub against the cigarette packs to stop them. However, due to the small contact area between the airbags and the cigarette packs, the airbag surfaces are prone to wear, making it difficult to stop the cigarette packs promptly and accurately. When the airbags wear out, the entire braking system needs to be adjusted to ensure timely and accurate stopping, but the adjustment process is unpredictable. Furthermore, when the airbags are severely worn, they need to be replaced, a cumbersome process that results in high time and labor costs for maintenance. Utility Model Content

[0004] The purpose of this utility model is to provide a cigarette pack braking mechanism and a cigarette pack packaging machine. The cigarette pack braking mechanism and the cigarette pack packaging machine ensure the braking effect of the cigarette pack and extend the replacement or maintenance cycle of the ejection component, so as to reduce the time and labor costs during production.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A cigarette pack braking mechanism, installed on the conveyor belt of a cigarette pack packaging machine, includes:

[0007] An ejector assembly is disposed on one side of the conveyor belt;

[0008] A braking assembly is driven to the output end of the ejection assembly and is disposed toward the conveyor belt. The ejection assembly is capable of ejecting the braking assembly toward the middle of the conveyor belt in the width direction to stop the cigarette packs on the conveyor belt.

[0009] As a further technical solution, the ejection component includes a brake airbag, which has two air inlets connected to an external positive pressure air source and a negative pressure air source, respectively. The brake assembly is connected to the side of the brake airbag near the conveyor belt.

[0010] As a further technical solution, the ejection assembly includes an ejection motor, and the braking assembly is drivenly connected to the output shaft of the ejection motor.

[0011] As a further technical solution, the brake assembly includes a brake push block and a guide limiting plate. The brake push block is connected to the ejection assembly, and the limiting guide plate is fixedly disposed on one side of the conveyor belt corresponding to the brake push block.

[0012] The brake pusher has a protruding push portion on its side wall near the guide limiting plate. The guide limiting plate has a guide limiting groove in its middle. The push-out component pushes the brake pusher so that the push portion extends from the guide limiting groove to the middle of the conveyor belt.

[0013] As a further technical solution, the guide limiting plate is provided with at least two guide limiting grooves at intervals in the middle, and the push-pack part is provided corresponding to the guide limiting grooves.

[0014] As a further technical solution, the distance between two adjacent guide limiting grooves is less than the thickness of the cigarette pack.

[0015] As a further technical solution, the guide limiting plate is provided with a guide positioning post, and the brake push block is provided with a guide channel on the side wall near the guide limiting plate to allow the guide positioning post to be inserted.

[0016] As a further technical solution, both ends of the guide limiting plate are bent towards the brake push block, and both ends of the guide limiting plate are provided with a locking interface that can be locked onto the guide strip in the cigarette packaging machine.

[0017] As a further technical solution, the brake assembly also includes a wear-resistant component, which is disposed on the side of the pusher portion opposite to the brake pusher block.

[0018] A cigarette packaging machine includes a packaging machine body, a conveyor belt, and a cigarette packaging brake mechanism. The conveyor belt is configured to correspond to the cigarette packaging outlet end of the packaging machine body. The cigarette packaging brake mechanism is configured on one side of the conveyor belt, and the brake component in the cigarette packaging brake mechanism is configured to face the conveyor belt.

[0019] Compared with the prior art, the technical advantages of the cigarette pack braking mechanism and cigarette pack packaging machine provided by this utility model are as follows:

[0020] 1. Because the brake assembly is located on one side of the conveyor belt via the ejector assembly, when the cigarette packs need to be stopped as they travel along the conveyor belt into the downstream equipment, the ejector assembly pushes the brake assembly towards the middle of the conveyor belt to stop the cigarette packs on the conveyor belt. In this process, the ejector assembly and the brake assembly work together to stop the cigarette packs and ensure a stopping effect. Simultaneously, when stopping the cigarette packs, the ejector assembly does not directly contact the cigarette packs, thus extending the replacement or maintenance cycle of the ejector assembly, reducing the number of times it needs to be replaced or maintained, and lowering time and labor costs in the production process.

[0021] 2. Since the conveyor belt is positioned corresponding to the cigarette pack outlet of the packaging machine body, the cigarette pack braking mechanism is located on one side of the conveyor belt. Therefore, during the process of conveying the cigarette pack from the packaging machine body to the downstream equipment, the cigarette pack can be stopped by the cooperation of the ejection component and the braking component, depending on the packaging situation, to ensure the stopping effect. At the same time, direct contact between the ejection component and the cigarette pack is avoided, thereby reducing the number of times the ejection component needs to be replaced or repaired, and thus reducing the time and labor costs in the production process.

[0028] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0029] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0030] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0031] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0032] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0033] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0034] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0035] Combination Figure 1 and Figure 2 As shown, the cigarette pack braking mechanism provided in this embodiment is installed on the conveyor belt (not shown in the figure) of a cigarette pack packaging machine (not shown in the figure). It brakes the cigarette packs according to the actual production and processing conditions, ensuring a braking effect and extending the replacement or maintenance cycle of the ejection component, thereby reducing time and labor costs during production. The cigarette pack packaging machines to which this braking mechanism is applicable include, but are not limited to, the FK701 packaging machine and the F8 packaging machine. Specifically, the cigarette pack braking mechanism includes an ejection component and a braking component 200: the ejection component is located on one side of the conveyor belt; the braking component 200 is driven at the output end of the ejection component and faces the conveyor belt. The ejection component can push the braking component 200 towards the middle of the conveyor belt to stop the cigarette packs on the conveyor belt.

[0036] Because the brake assembly 200 is mounted on one side of the conveyor belt via the ejector assembly, when the cigarette pack needs to be stopped as it travels along the conveyor belt into the downstream equipment, the ejector assembly pushes the brake assembly 200 towards the middle of the conveyor belt to stop the cigarette pack on the conveyor belt. During this process, the ejector assembly and the brake assembly 200 cooperate to stop the cigarette pack and ensure a stopping effect. Simultaneously, when stopping the cigarette pack, the ejector assembly does not directly contact the cigarette pack, thus extending the replacement or maintenance cycle of the ejector assembly, reducing the number of times it needs to be replaced or maintained, thereby lowering time and labor costs in the production process.

[0037] Preferably, the ejection assembly includes a brake airbag 110, which has two air inlets connected to an external positive pressure air source and a negative pressure air source, respectively. The brake assembly 200 is connected to the side of the brake airbag 110 near the conveyor belt.

[0038] When it is necessary to stop the cigarette packs on the conveyor belt, the brake airbag 110 is inflated by the positive pressure air source, so that the brake airbag 110 can quickly inflate and the brake assembly 200 can quickly and accurately stop the cigarette packs. When it is necessary to continue conveying the stopped cigarette packs on the conveyor belt, the air in the brake airbag 110 is quickly discharged by the negative pressure air source, so that the brake airbag 110 can quickly retract, so that the cigarette packs on the conveyor belt can be released in time, thereby ensuring the overall processing and production rate.

[0039] A single brake airbag 110 can be provided, which can speed up the replacement process when the airbag needs to be replaced; or, multiple brake airbags 110 can be provided at intervals along the conveyor belt conveying direction, with the side of each brake airbag 110 near the conveyor belt connected to the brake assembly 200. In this way, when it is necessary to stop the cigarette packs on the conveyor belt, multiple brake airbags 110 will inflate simultaneously to ensure the smoothness of the brake assembly 200 when it is pushed out, thereby further improving the stopping effect on the cigarette packs.

[0040] In some other embodiments, the ejection assembly includes an ejection motor (not shown in the figure), and a brake assembly 200 is drivenly connected to the output shaft of the ejection motor. The output shaft of the ejection motor is capable of autonomous extension and retraction in the direction from the ejection motor to the conveyor belt, and the output shaft of the ejection motor is perpendicular to the conveying direction of the conveyor belt; by extending or retracting the output shaft of the ejection motor, the brake assembly 200 is driven to stop the cigarette pack or release the stopped cigarette pack. The specific structure and working principle of the ejection motor are described in accordance with existing technology and will not be repeated here.

[0041] Preferably, the brake assembly 200 includes a brake push block 210 and a guide limiting plate 220. The brake push block 210 is connected to the ejection assembly, and the limiting guide plate is fixedly disposed on one side of the conveyor belt corresponding to the brake push block 210. The side wall of the brake push block 210 near the guide limiting plate 220 is provided with a push portion 211, and the guide limiting plate 220 is provided with a guide limiting groove 221 in the middle. When the ejection assembly pushes the brake push block 210, the push portion 211 can extend from the guide limiting groove 221 to the middle of the conveyor belt.

[0042] Specific combination Figure 1 and Figure 2As shown, the pusher portion 211 and the guide limiting groove 221 cooperate with each other to guide the brake pusher 210 to always be pushed out along a predetermined path when the brake pusher 210 is pushed out, so as to ensure the stability when the cigarette pack is stopped. At the same time, the brake pusher 210 and the guide limiting groove 221 cooperate with each other to limit the distance that the brake pusher 210 is pushed out, so as to avoid the brake pusher 210 being pushed out too much, causing the stopped cigarette pack to be squeezed and deformed. The dimensions of the guide limiting groove 221, the pusher portion 211 and the brake pusher 210 are adapted to actual needs and are not specifically limited here. In some other embodiments, the guide limiting plate 220 may not be provided, and only the brake pusher 210 is provided.

[0043] To reduce the damage to the cigarette pack caused by the brake push block 210, the brake push block 210 is preferably made of a non-metallic material with low hardness. In this embodiment, the brake push block 210 is made of nylon material.

[0044] Preferably, in order to further improve the guiding and limiting effect of the brake push block 210, at least two guiding and limiting grooves 221 are provided at intervals in the middle of the guide limiting plate 220, and the push block part 211 is correspondingly provided with the guiding and limiting grooves 221.

[0045] Specifically, in this embodiment, along the height direction, the guide limiting plate 220 has two guide limiting grooves 221 spaced apart at its center, and the brake push block 210 has two corresponding push parts 211. When the push assembly pushes the brake push block 210, the two push parts 211 extend one-to-one from the two guide limiting grooves 221 to the center of the conveyor belt, ensuring both the guiding and limiting effects on the brake push block 210, while also ensuring the braking effect on the cigarette packs on the conveyor belt. Furthermore, when braking the cigarette packs, to avoid the cigarette packs getting stuck between the two push parts 211 and affecting the overall production process, the distance between two adjacent guide limiting grooves 221 is less than the thickness of the cigarette pack, that is, the distance between the two push parts 211 is less than the thickness of the cigarette pack.

[0046] Furthermore, the guide limiting plate 220 is provided with guide positioning posts (not shown in the figure), and the brake push block 210 is provided with a guide channel 212 near the side wall of the guide limiting plate 220 to allow the insertion of the guide positioning posts. During the process of the push assembly pushing the brake push block 210, the guide channel 212 cooperates with the guide positioning posts to further limit the relative position of the brake push block 210 and the guide limiting plate 220, guiding the brake push block 210 to always be pushed out along a predetermined route, so as to further improve the braking effect on the cigarette pack.

[0047] To further enhance the structural strength of the guide limit plate 220 and thus ensure the braking effect on the cigarette pack, both ends of the guide limit plate 220 are bent towards the brake push block 210. To further improve the connection strength, connection stability, and connection convenience of the guide limit plate 220, both ends of the guide limit plate 220 are provided with locking interfaces 222 that can be engaged with the guide strip in the cigarette pack packaging machine. The guide limit plate 220 is engaged with the guide strip in the cigarette pack packaging machine through the two locking interfaces 222. The setting position and shape of the locking interfaces 222 are set according to the corresponding guide strip and are not specifically limited here.

[0048] Preferably, to further slow down the wear rate of the brake pusher 210, in this embodiment, the brake assembly 200 further includes a wear-resistant component 230, which is disposed on the side of the pusher portion 211 opposite to the brake pusher 210. The wear-resistant component 230 can be made of rubber, silicone, or injection molded material, depending on the actual situation, and no specific limitation is made here.

[0049] The cigarette packaging machine includes a packaging machine body, a conveyor belt, and a cigarette packaging brake mechanism. The conveyor belt is positioned corresponding to the cigarette packaging outlet end of the packaging machine body. The cigarette packaging brake mechanism is located on one side of the conveyor belt, and the brake component 200 in the cigarette packaging brake mechanism faces the conveyor belt.

[0050] Because the conveyor belt is positioned corresponding to the cigarette pack outlet of the packaging machine body, and the cigarette pack braking mechanism is located on one side of the conveyor belt, the cigarette pack can be stopped by the push-out component and the braking component 200 working together to ensure a stopping effect, while avoiding direct contact between the push-out component and the cigarette pack. This reduces the frequency of replacement or maintenance of the push-out component, thereby lowering time and labor costs in the production process.

[0051] 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.
