Description

Technical Field

[0001] This invention relates to the field of special filter rod manufacturing technology for tobacco, and in particular to a filling manifold device for a visible cavity filter rod. Background Technology

[0002] Currently, a variety of substances are added to the cavity of composite visible cavity filter rods, including inorganic clay particles, flavoring carrier particles, and injection components. These substances greatly improve the filtration efficiency of cigarette filters for harmful substances such as tar and nicotine, reduce the harm of cigarettes to the human body, and enhance the visual effect of cigarettes.

[0003] Using injection-molded parts (rubber injection molded parts formed by an injection molding machine, which serve both aesthetic and smoke-guiding functions after being inserted into the visible cavity filter rod) as the filler for the visible cavity filter rod places high demands on the molding equipment. From the feeding and transfer of the injection parts to the filling, precision and stability are required. Due to the large quantity of parts being filled, a confluence device is needed to centrally and precisely distribute the parts and stably transfer them onto the conveyor belt, achieving accurate and efficient turnover and transfer of the parts from suction to delivery to the molding machine. Currently, precise transfer of injection molded filter rods in the production of visible cavity injection molded filter rods cannot be achieved. This is because multiple injection molded filter rods are transferred together during the transfer process. The individual injection molded filter rods are then separated manually or mechanically to ensure that each injection molded filter rod is spaced a certain distance apart and can be filled into different filter rods. However, because the traditional method cannot effectively separate the injection molded filter rods, multiple injection molded filter rods are mixed together. As a result, multiple injection molded filter rods cannot be effectively separated during the transfer process, and when they are subsequently filled into the visible cavity injection molded filter rods, the injection molded filter rods cannot be filled into the filter rods in a one-to-one correspondence. This requires manual intervention, which increases labor costs and significantly reduces the filling efficiency of the filter rods. Summary of the Invention

[0004] The purpose of this invention is to solve at least one technical problem in the background art and to provide a filling manifold device for a visible cavity filter rod.

[0005] To achieve the above objectives, the present invention provides a filling manifold device for a visible cavity filter rod, comprising: a filling conveying assembly and a filling manifold transmission assembly; The injection unit bus transmission assembly includes: a bracket, a busbar structure, and a first drive motor; The injection component conveying assembly conveys the injection components to the manifold structure supported on the bracket. The manifold structure is rotated by the drive motor. Each injection component entering the manifold structure enters the transfer channel of the connecting filter rod according to the required spacing through the rotation of the manifold structure.

[0006] According to one aspect of the present invention, the busbar structure includes: a first busbar, a second busbar, and a third busbar; The first busbar and the second busbar have the same dimensions and specifications; The third busbar is larger than the first busbar and the second busbar; The third busbar is located between the first busbar and the second busbar, and receives the components transmitted through the first busbar and the second busbar.

[0007] According to one aspect of the present invention, the first busbar, the second busbar, and the third busbar each include: a turntable and a housing; The center of the turntable is connected to the output shaft of the first drive motor; The turntable is rotatably supported in the housing, and a casting transfer channel is formed between the circumferential outer wall of the turntable and the inner wall of the housing; The turntable has teeth spaced apart on its circumferential outer wall, through which each component entering the transmission channel is transferred; The housing of the first manifold and the housing of the second manifold are provided with injection inlets.

[0008] According to one aspect of the invention, the first busbar and the third busbar are arranged longitudinally, one side of the housing of the first busbar and one side of the housing of the third busbar communicate to form a first communication portion, and the width of the channel formed at the first communication portion is the same as the width of the transmission channel.

[0009] According to one aspect of the invention, the second busbar and the third busbar are arranged laterally, one side of the housing of the second busbar communicates with the other side of the housing of the third busbar to form a second communication portion, and the width of the channel formed at the second communication portion is the same as the width of the transmission channel.

[0010] According to one aspect of the present invention, the injection component conveying assembly includes: a first injection component conveying structure and a second injection component conveying structure; The first component transfer structure is configured to correspond to the first busbar, and transfers externally transferred components to the first busbar. The second component transfer structure is configured to correspond to the second busbar, and transfers externally transferred components to the second busbar.

[0011] According to one aspect of the present invention, both the first injection component conveying structure and the second injection component conveying structure include: a second drive motor, a drive wheel, a conveyor belt, a driven wheel, an injection component feeding wheel, and an injection component transmission pipe; The drive wheel is mounted on the output shaft of the second drive motor; The conveyor belt connects the driving wheel and the driven wheel; The driven wheel is connected to the injection delivery wheel via a rotating shaft; The injection delivery wheel is rotatably mounted on the outer wall of the bracket and is positioned opposite to the first or second manifold in the bracket; The injection transfer pipe is connected to an external injection delivery device, receives the injection delivered by the injection delivery device, and transfers the injection to the mating point between the injection delivery wheel and the injection inlet. The injection is then delivered into the transmission channel of the first manifold or the second manifold through the injection delivery wheel.

[0012] According to one aspect of the present invention, the outer wall of the injection delivery wheel is provided with an arc-shaped groove, the two ends of the arc-shaped groove being aligned with the outer wall of the bracket. When the arc-shaped groove rotates to the injection transmission pipe, it receives the injection through the injection transmission pipe. When the arc-shaped groove rotates to the injection inlet, it squeezes the injection into the transmission channel of the first manifold or the second manifold through the arc-shaped groove.

[0013] According to one aspect of the invention, the injection transfer tube is a transparent injection transfer tube.

[0014] According to one aspect of the present invention, the busbar structure includes: a first busbar, a second busbar, and a third busbar; the first and second busbars are of the same size; the third busbar is larger than the first and second busbars; the third busbar is located between the first and second busbars and receives the injection components transferred through the first and second busbars. This arrangement allows the first and second busbars to receive injection components transferred from the injection component transfer assembly, and then the injection components received by the first and second busbars are uniformly transferred to the third busbar, which then transfers the collected injection components at appropriate intervals into the transfer channel connecting the filter rod.

[0015] According to one aspect of the present invention, the first, second, and third busbars each include: a turntable and a housing; the center of the turntable is connected to the output shaft of a first drive motor; the turntable is rotatably supported in the housing, and a component transfer channel is formed between the outer circumferential wall of the turntable and the inner wall of the housing; teeth are spaced apart on the outer circumferential wall of the turntable, and the components entering the transfer channel are transferred by the teeth; the housings of the first and second busbars are provided with component inlets. This arrangement allows the first and second busbars to receive components transferred from the component transfer assembly through the component inlets. The received components flow into the component transfer channel formed between the outer circumferential wall of the turntable and the inner wall of the housing. The components located in the component transfer channel are moved by the teeth as the turntable rotates, and the moving speed can be adjusted as needed, making the spacing between the components more precise and reliable.

[0016] According to one aspect of the present invention, a first busbar and a third busbar are arranged longitudinally. One side of the housing of the first busbar and one side of the housing of the third busbar are connected to form a first connecting portion, and the width of the channel formed at the first connecting portion is the same as the width of the transmission channel. This arrangement allows the filler material transmitted through the first busbar to smoothly enter the third busbar through the first connecting portion. The third busbar uses teeth to separate the filler materials from the first and second busbars for transmission, maintaining a spacing between the filler materials and making the subsequent filling of the visible cavity filter rod more precise and stable.

[0017] According to one aspect of the present invention, the second and third busbars are arranged laterally. One side of the housing of the second busbar is connected to the other side of the housing of the third busbar to form a second connecting portion, and the width of the channel formed at the second connecting portion is the same as the width of the transmission channel. This arrangement allows the filler material transmitted through the second busbar to smoothly enter the third busbar through the second connecting portion. The third busbar uses teeth to separate the filler materials from the second and first busbars for transmission, maintaining a spacing between the filler materials and making the subsequent filling of the visible cavity filter rod more precise and stable.

[0018] According to one aspect of the present invention, the filling component conveying assembly includes: a first filling component conveying structure and a second filling component conveying structure; the first filling component conveying structure is configured corresponding to a first busbar and conveys externally delivered filling components to the first busbar; the second filling component conveying structure is configured corresponding to a second busbar and conveys externally delivered filling components to the second busbar. This configuration allows corresponding filling components to be conveyed to different busbars in the required order via different filling component conveying structures, ensuring that the filling components in different busbars are conveyed in the corresponding order. This ensures that the filling components finally converged to the third busbar can accurately and sequentially enter their corresponding positions for further conveying, guaranteeing more precise and stable filling of the visible cavity filter rod.

[0019] According to one aspect of the present invention, both the first and second injection component conveying structures include: a second drive motor, a drive wheel, a conveyor belt, a driven wheel, an injection component feeding wheel, and an injection component transmission pipe; the drive wheel is mounted on the output shaft of the second drive motor; the conveyor belt connects the drive wheel and the driven wheel; the driven wheel is connected to the injection component feeding wheel via a rotating shaft; the injection component feeding wheel is rotatably mounted on the outer wall of the support and is positioned opposite to the first or second manifold in the support; the injection component transmission pipe is connected to an external injection component feeding device, receives the injection component fed by the injection component feeding device, and transmits the injection component to the mating point between the injection component feeding wheel and the injection component inlet, and the injection component is fed into the transmission channel of the first or second manifold through the injection component feeding wheel. This configuration allows for the guidance and transport of components delivered by the external component delivery device via the component transfer pipe, guiding the components to the mating position between the component delivery wheel and the component inlet. The second drive motor, drive wheel, conveyor belt, and driven wheel can rotate the component delivery wheel. The rotating component delivery wheel, through the structural arrangement on its end face, squeezes the components into the transmission channel of the first or second manifold. This allows the transmission time interval between components to be adjusted according to the rotation speed of the component delivery wheel, making the spacing between components adjustable during the manifolding process. This ensures precise delivery and positioning of components according to production needs, guaranteeing the filling accuracy of the visible cavity filter rod.

[0020] According to one aspect of the present invention, the outer wall of the injection delivery wheel is provided with an arc-shaped groove, the two ends of which are aligned with the outer wall of the support. When the arc-shaped groove rotates to the injection transfer pipe, it receives the injection part guided and transferred through the injection transfer pipe. After receiving the injection part, it stores it and drives the injection part to continue rotating along the outer wall of the support. When the arc-shaped groove rotates to the injection inlet, it squeezes the injection part into the transmission channel of the first or second manifold through the arc-shaped groove. This configuration allows the injection delivery wheel to receive one unit of injection part at a corresponding position with each rotation and deliver the injection part to the transmission channel of the manifold at another corresponding position. The entire process is fast and precise. Moreover, the rotation speed of the injection delivery wheel follows the rotation speed of the second drive motor, which is a servo motor. During the control of the rotation of the injection delivery wheel, the rotation speed can be adjusted as needed. This configuration allows for adjustable spacing between the injection parts entering the injection manifold transmission assembly, effectively improving the timing and accuracy of transmission and increasing production efficiency.

[0021] According to one aspect of the present invention, the injection transfer tube is a transparent injection transfer tube. This configuration allows for observation of whether the quantity of injections delivered to the device of the present invention meets production requirements, enabling timely detection of material delivery status in the early stages of production and avoiding problems such as ineffective separation of injections and filter rod filling failures caused by material delivery errors.

[0022] According to the above-described scheme of this invention, the present invention transports the injection parts through two channels, utilizes an injection part delivery wheel (similar to the principle of a cam mechanism) to achieve interval delivery and precise separation of each injection part, and relies on two dials (dials with teeth) for stable transmission, finally handing the injection parts over to the final confluence plate (third confluence plate), from which they are transferred to the conveyor belt (transfer channel connecting to the cigarette holder), completing the entire separation and transfer process. This device effectively solves the problems of inaccurate injection part separation and unstable transmission in traditional technologies, improving production efficiency and product quality, and is particularly suitable for production scenarios where cylindrical injection parts are added to visible cavity filter rods. The present invention has a compact structure, and through the combination of reciprocating motion of the wheel structure and linear transmission, it achieves efficient and stable transmission of the injection parts, and has good application prospects.

[0023] According to the above-described solution of the present invention, the present invention can effectively solve the problem that individual injection parts cannot be effectively separated or the spacing cannot be controlled during the production process of visible cavity injection filter rods. By controlling the running speed of the two injection part feeding rollers and the running speed of the three manifolds, the spacing between each injection part can be effectively controlled. Through the effective operation of each servo motor, the stability of injection part separation and transmission is greatly improved, further enhancing the accuracy of injection part filling of visible cavity filter rods, and improving production quality, production efficiency, and product qualification rate. The three manifolds of the present invention have high precision, enabling precise positioning and transmission of injection parts. Attached Figure Description

Detailed Implementation

[0025] The invention will now be discussed with reference to exemplary embodiments. It should be understood that the described embodiments are merely intended to enable those skilled in the art to better understand and thus implement the invention, and are not intended to imply any limitation on the scope of the invention.

[0026] As used herein, the term "comprising" and its variations are to be interpreted as open-ended terms meaning "including but not limited to". The term "based on" is to be interpreted as "at least partially based on". The terms "one embodiment" and "an embodiment" are to be interpreted as "at least one embodiment".

[0027] Figure 1 A schematic top view of a filling manifold device for a visible cavity filter rod according to an embodiment of the present invention; Figure 2This schematic diagram shows a side view of the injection manifold of a visible cavity filter rod according to an embodiment of the present invention. Figure 1 and Figure 2 As shown, in this embodiment, the injection manifold device for the visible cavity filter rod includes: an injection conveying assembly 1 and an injection manifold transmission assembly 2. The injection unit bus transmission assembly 2 includes: a bracket 3, a busbar structure 4, and a first drive motor 5; The injection component conveying assembly 1 conveys the injection components to the manifold structure 4 supported on the bracket 3. The manifold structure 4 is rotated by the first drive motor. Each injection component entering the manifold structure 4 is coordinated by the rotation of the manifold structure 4 and enters the transmission channel of the connecting filter rod according to the required spacing.

[0028] Furthermore, such as Figure 1 and Figure 2 As shown, in this embodiment, the busbar structure 4 includes: a first busbar 6, a second busbar 7, and a third busbar 8; The first busbar 6 and the second busbar 7 have the same dimensions and specifications; The third busbar 8 is larger than the first busbar 6 and the second busbar 7; The third busbar 8 is located between the first busbar 6 and the second busbar 7, and receives the injection components transmitted through the first busbar 6 and the second busbar 7. This arrangement allows the injection components received from the injection component transmission assembly 1 via the first busbar 6 and the second busbar 7 to be uniformly transmitted to the third busbar 8. The third busbar 8 then transmits the collected injection components at appropriate intervals into the transmission channel connecting the filter rod.

[0029] Furthermore, such as Figure 1 and Figure 2 As shown, in this embodiment, the first busbar 6, the second busbar 7, and the third busbar 8 each include: a turntable 9 and a housing 10; The center of turntable 9 is connected to the output shaft of the first drive motor 5; The turntable 9 is rotatably supported in the housing 10, and a casting transfer channel is formed between the circumferential outer wall of the turntable 9 and the inner wall of the housing 10. The turntable 9 has teeth 11 spaced apart on its circumferential outer wall, which are used to transfer the various injection parts that enter the transmission channel. The housings 10 of the first and second busbars 6 and 7 are provided with injection inlets 20. This arrangement allows the first and second busbars 6 and 7 to receive injections from the injection transfer assembly 1 through the injection inlets 20. The received injections flow into the injection transfer channel 22 formed between the outer circumferential wall of the turntable 9 and the inner wall of the housing 10. The injections located in the injection transfer channel 22 are moved by the prying teeth 11 as the turntable 9 rotates. The moving speed can be adjusted as needed, making the spacing between the injections more precise and reliable.

[0030] In this embodiment, the difference between the third busbar 8 and the first busbar 6 and the second busbar 7 is that the turntable 9 and the housing 10 in the third busbar 8 are larger, and there are more teeth 11 arranged on the outer circumference of the turntable 9.

[0031] In this embodiment, the first drive motor 5 is a servo motor. The servo motor can control the running speed of the first busbar 6 and the second busbar 7 to control the spacing between the two corresponding injection parts in the first busbar 6 and the second busbar 7 respectively. This ensures that the spacing between the two injection parts after entering the third busbar 8 meets the requirements, so that when the third busbar 8 transfers the injection parts, the transfer accuracy of the injection parts is higher, and the filling of the visible cavity filter rod is more accurate and stable.

[0032] Furthermore, such as Figure 1 As shown, in this embodiment, the first busbar 6 and the third busbar 8 are arranged longitudinally. One side of the housing 10 of the first busbar 6 and one side of the housing 10 of the third busbar 8 are connected to form a first connecting portion 12, and the width of the channel formed at the first connecting portion 12 is the same as the width of the transmission channel. This arrangement allows the filler material transmitted through the first busbar 6 to smoothly enter the third busbar 8 through the first connecting portion 12. The third busbar 8 uses teeth 11 to separate the fillers from the first busbar 6 and the second busbar 7 for transmission, maintaining spacing between each filler material. This makes the subsequent filling of the visible cavity filter rod more precise and stable. Finally, the separated fillers are conveyed to the transmission channel of the connecting filter rod through the filler material outlet 23. Furthermore, such as Figure 1As shown, in this embodiment, the second busbar 7 and the third busbar 8 are arranged laterally. One side of the housing 10 of the second busbar 7 is connected to the other side of the housing 10 of the third busbar 8 to form a second connecting portion 13, and the width of the channel formed at the second connecting portion 13 is the same as the width of the transmission channel. This arrangement allows the filler material transmitted through the second busbar 7 to smoothly enter the third busbar 8 through the second connecting portion 13. The third busbar 8 uses teeth 11 to separate the filler materials from the second busbar 7 and the first busbar 6 for transmission, maintaining a distance between each filler material, thus making the subsequent filling of the visible cavity filter rod more precise and stable.

[0033] Furthermore, such as Figure 1 and Figure 2 As shown, in this embodiment, the injection component conveying assembly 1 includes: a first injection component conveying structure and a second injection component conveying structure. The first component conveying structure is set to correspond to the first busbar 6, and conveys the externally conveyed components to the first busbar 6; The second component conveying structure is configured corresponding to the second manifold 7, conveying externally delivered components to the second manifold 7. This configuration allows different component conveying structures to deliver components to different manifolds in the required order, ensuring that components in different manifolds are conveyed in the correct sequence. This guarantees that the components finally converging into the third manifold 8 can accurately and sequentially enter their corresponding delivery positions, ensuring more precise and stable filling of the visible cavity filter rod.

[0034] Furthermore, such as Figure 1 and Figure 2 As shown, in this embodiment, both the first injection component conveying structure and the second injection component conveying structure include: a second drive motor 14, a drive wheel 15, a conveyor belt 16, a driven wheel 17, an injection component feeding wheel 18, and an injection component transmission pipe 19. The drive wheel 15 is mounted on the output shaft of the second drive motor 14; Conveyor belt 16 connects drive wheel 15 and driven wheel 17; Driven wheel 17 is connected to injection casting wheel 18 via a rotating shaft; The injection component delivery wheel 18 is rotatably mounted on the outer wall of the bracket 3 and is positioned opposite to the first manifold 6 or the second manifold 7 in the bracket 3; The injection transfer pipe 19 is connected to an external injection delivery device, receives the injections delivered by the injection delivery device, and transfers the injections to the mating point between the injection delivery wheel 18 and the injection inlet 20. The injections are then sent into the transmission channel of the first busbar 6 or the second busbar 7 via the injection delivery wheel 18. This configuration allows for the guidance and transmission of components delivered by the external component delivery device via the component transfer pipe 19, guiding the components to the mating position between the component delivery wheel 18 and the component inlet 20. The second drive motor 14, the drive wheel 15, the conveyor belt 16, and the driven wheel 17 can drive the component delivery wheel 18 to rotate. The rotating component delivery wheel 18, through the structural arrangement on its end face, squeezes the components into the transmission channel of the first manifold 6 or the second manifold 7, allowing the transmission time interval between each component to be adjusted according to the rotation speed of the component delivery wheel 18. This makes the spacing between components adjustable during the confluence process, ensuring precise delivery and positioning of components according to production needs, and guaranteeing the filling accuracy of the visible cavity filter rod.

[0035] Furthermore, such as Figure 1 and Figure 2 As shown, in this embodiment, the outer wall of the injection delivery wheel 18 is provided with an arc-shaped groove 21. The two ends of the arc-shaped groove 21 are aligned with the outer wall of the support 3. When the arc-shaped groove 21 rotates to the injection transmission pipe 19, it receives the injections guided and transmitted through the injection transmission pipe 19. After receiving the injections, it stores them and drives the injections to continue rotating along the outer wall of the support 3. When the arc-shaped groove 21 rotates to the injection inlet 20, it squeezes the injections into the transmission channel of the first manifold 6 or the second manifold 7 through the arc-shaped groove 21. With this configuration, the injection delivery wheel 18 can receive one unit of injection at the corresponding position for each rotation and deliver the injection to the transmission channel of the manifold at another corresponding position. The whole process is fast and accurate. Moreover, the rotation speed of the injection delivery wheel 18 is the same as the rotation speed of the second drive motor 14. In this embodiment, the second drive motor 14 is a servo motor, and the rotation speed can be adjusted as needed during the control of the rotation of the injection delivery wheel 18. This configuration allows for adjustable spacing between individual injection components entering the injection component busbar transmission assembly 2, effectively improving transmission timing and accuracy, and increasing production efficiency.

[0036] Furthermore, in this embodiment, the injection transfer tube 19 is a transparent injection transfer tube. This configuration allows for observation of whether the quantity of injections delivered to the device of the present invention meets production requirements, enabling timely detection of material delivery status in the early stages of production and avoiding problems such as ineffective separation of injections and failure of filter rod filling caused by material delivery errors.

[0037] According to the above-described scheme of this invention, the present invention conveys the injection parts through two channels, utilizes an injection part delivery wheel (similar to the principle of a cam mechanism) to achieve interval delivery and precise separation of each injection part, and relies on two dials (dials with teeth) for stable transmission, finally handing the injection parts over to the final manifold (third manifold), from which they are transferred to the conveyor belt (the transfer channel connecting the filter rod), completing the entire separation and transfer process. This device effectively solves the problems of inaccurate injection part separation and unstable transmission in traditional technologies, improving production efficiency and product quality, and is particularly suitable for production scenarios where cylindrical injection parts are added to visible cavity filter rods. The present invention has a compact structure, and through the combination of the reciprocating motion of the wheel structure and linear transmission, it achieves efficient and stable transmission of the injection parts, and has good application prospects.

[0038] According to the above-described solution of the present invention, the present invention effectively solves the problem that individual injection parts cannot be effectively separated or the spacing cannot be controlled during the production process of visible cavity injection filter rods. By controlling the running speed of the two injection part feeding rollers and the running speed of the three manifolds, effective control of the spacing between individual injection parts is achieved. Through the effective operation of each servo motor, the stability of injection part separation and transmission is greatly improved, further enhancing the accuracy of injection part filling of the corresponding visible cavity filter rod, thereby improving production quality and efficiency. The three manifolds of the present invention have high precision, enabling accurate positioning and transmission of the injection parts.
