Description

Technical Field

[0001] This utility model relates to the field of tobacco manufacturing technology, and in particular to a glue supply system for cigarette machines. Background Technology

[0002] A cigarette rolling machine is a device that uses cigarette paper to wrap tobacco shreds and roll them into cigarette sticks. Current cigarette rolling machines generally wrap tobacco shreds in a large sheet of cigarette paper, apply adhesive to the paper, and roll it into a long cigarette stick, for example, with a diameter of 8mm. Then, it is cut into the required length. In this process, the quality of the adhesive application directly affects the quality of the cigarette stick. Adhesive supply is a crucial component of the adhesive application process, and whether the adhesive is supplied evenly directly impacts the coating effect.

[0003] The glue supply system is used to provide a continuous and quantitative amount of adhesive to the gluing device during the rolling and forming process, enabling the gluing device to continuously and evenly apply glue lines to the cigarette paper, thus bonding the joints. Currently, the SE glue supply system of the ZJ116A model rolling and splicing unit suffers from serious clogging problems. Frequent clogging leads to insufficient glue flow or interruption of glue application at the cigarette strip joints, easily causing the cigarette rolls to slip or the cigarettes to burst at the joints, resulting in a high frequency of maintenance. Moreover, the clogging is greatly affected by seasonal temperature, requiring frequent cleaning and maintenance of the glue circuit, which is not only time-consuming and labor-intensive but also seriously affects equipment efficiency and product quality, potentially producing a large number of cigarettes with Class A quality defects and burst joints.

[0004] The ZJ116A model's glue tank uses a double-layer filter screen with a small gap in the original equipment, which is not only prone to getting dirty and clogging, but also difficult to clean thoroughly, resulting in incomplete filtration of impurities in the glue. If these impurities enter the subsequent glue pump and glue gun, they may also cause blockages. The existing glue supply system requires cleaning 2-3 times a month, each time requiring about 2 hours of hot water cleaning. Furthermore, the gap between the double-layer filter screens is difficult to clean properly, and subsequent clogging of the mesh will hinder glue flow, affecting the spraying pressure. Unstable spraying pressure will severely impact the quality of the glue application. Utility Model Content

[0016] As an optional technical solution for the glue supply system of a cigarette machine, a handle is provided on the upper surface of the filter inside the barrel.

[0017] As an optional technical solution for the glue supply system of a cigarette machine, the pipeline filter includes an external connector and an internal filter. The internal filter is sleeved inside the external connector.

[0022] The glue supply system for cigarette machines provided by this utility model includes a glue tank, an internal filter, a delivery pipe, and a pipeline filter. The glue tank includes a tank body and a lid, which are detachably connected. The glue tank is used to fill glue and can be sealed. The internal filter is detachably fixed inside the tank body.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0030] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0032] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0033] like Figures 1 to 4As shown, this utility model discloses a glue supply system for a cigarette machine, including a glue tank 1, an in-tank filter 2, a conveying pipe 3, and a pipeline filter 4. The glue tank 1 includes a tank body and a lid, which are detachably connected. The glue tank 1 is used to fill glue and can be sealed. The in-tank filter 2 is detachably fixed inside the tank body. The inner diameter at the interface between the tank body and the lid is larger than the outer diameter of the in-tank filter 2, so that the in-tank filter 2 can smoothly enter and exit the tank body. One end of the conveying pipe 3 extends into the glue tank 1 and communicates with the interior of the in-tank filter 2. The improved structure allows the glue to undergo a first filtration before entering the conveying pipe 3, ensuring that most of the impurities in the glue are removed, thus not affecting the subsequent second filtration. The pipeline filter 4 is detachably connected to the interruption position of the conveying pipe 3. The glue flowing into the conveying pipe 3 undergoes a second filtration through the pipeline filter 4 and then flows out of the conveying pipe 3, protecting the service life of the pipeline filter 4. The separate dual filtration system has a simple structure, replacing the original double-layer filter screen with a small gap. This avoids clogging, facilitates separate cleaning, and helps improve the filtration effect. It ensures the effectiveness of the glue pump and glue gun connected to the cigarette machine glue supply system, while the glue spraying pressure is relatively stable, which can effectively guarantee the glue spraying quality, reduce downtime for equipment maintenance, improve product quality, and thus increase the effective operating rate of the equipment.

[0034] In this embodiment, the in-bucket filter 2 is configured as a cylindrical structure with both upper and lower ends closed, and the lower end of the in-bucket filter 2 is connected to the delivery pipe 3. Several first filter holes are evenly spaced along the circumferential side of the cylindrical in-bucket filter 2. This arrangement ensures that the in-bucket filter 2 can uniformly contact and filter the glue around its perimeter. For example, the in-bucket filter 2 is coaxially arranged with the glue bucket 1, resulting in a more stable and uniform glue flow rate, more balanced force on the in-bucket filter 2, and extended service life. Simultaneously, the in-bucket filter 2 faces the opening of the bucket body, facilitating replacement, cleaning, and installation.

[0035] Furthermore, a connecting post 11 is provided at the bottom of the inner cavity of the glue bucket 1, and a glue outlet is provided in the axial direction of the connecting post 11. The lower end face of the internal filter 2 is sleeved on the connecting post 11. The connecting post 11 is used to position the internal filter 2. The interior of the internal filter 2 is connected to the glue outlet. The conveying pipe 3 is fixedly connected to the connecting post 11 and is connected to the glue outlet. By reconnecting the conveying pipe 3 to the glue bucket 1 for fixation, the structure can be made more stable, preventing the conveying pipe 3 from floating and facilitating the replacement of the internal filter 2. At the same time, this operation will not affect other structures.

[0036] For example, the lower end face of the in-bucket filter 2 is provided with a first threaded hole at the center position, and the outer wall of the connecting post 11 is provided with an external thread. The first threaded hole is threadedly connected to the connecting post 11, which further facilitates the disassembly and assembly of the in-bucket filter 2 and the glue bucket 1.

[0037] Specifically, the upper end of the filter 2 is provided with a handle to facilitate lifting the filter 2 out of the plastic bucket 1.

[0038] Optionally, handles can be selectively installed on the barrel body and the barrel lid to facilitate handling and operation of the switch.

[0039] Understandably, an injection hole is provided in the center of the lid. When injecting glue, the glue material can be injected into the glue container 1 through the injection hole. The glue material input device is connected to the injection hole to prevent impurities in the environment from falling into the glue container 1 if the lid is open. The injection hole is equipped with a cap to block the injection hole when no glue material is being input. The lid and the body of the container are only opened when cleaning the inside or replacing the filter 2 inside the container.

[0040] For example, the glue bucket 1 is placed vertically, and the inner circumference of the bucket lid is covered with a filter screen. The filter screen is spaced between the glue injection hole and the bucket body. During the process of the glue material being poured into the bucket from the glue injection hole on the lid and accumulating, it will pass through the filter screen and be pre-filtered and screened by the gravity of the glue material itself. This provides an extra layer of protection and disperses the impact force of the glue material on the filter 2 inside the bucket when it is poured.

[0041] In this embodiment, the pipeline filter 4 includes an external connector 41 and an internal filter element 42. The internal filter element 42 is sleeved inside the external connector 41. One end of the delivery pipe 3 at the interrupted position extends into the external connector 41 and communicates with the interior of the internal filter element 42, while the other end communicates with the interior of the external connector 41. Both ends of the delivery pipe 3 at the interrupted position are detachably connected to the pipeline filter 4 for easy cleaning and replacement. The internal filter element 42 is provided with a plurality of second filter holes, the second filter holes having a smaller diameter than the first filter holes.

[0042] Specifically, the outer connector 41 can be configured as a cylindrical structure, with one end of the cylindrical structure closed and the other end of the cylindrical structure open and provided with a second threaded hole. The inner filter element 42 is inserted into the outer connector 41, and an external thread is provided on the outer wall of one end of the inner filter element 42. The second threaded hole is threadedly connected to the inner filter element 42. The fixing method between the outer connector 41 and the inner filter element 42 is a threaded sleeve connection.

[0043] 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.
