Description

Technical Field

[0001] This invention relates to the field of novel smoke equipment technology, and in particular to a flexible press-fit device for smoke pipes. Background Technology

[0002] Currently, with the increasing awareness of health and environmental protection, various new types of cigarette products have emerged. The national plan clearly states that tobacco technology innovation is the core of the cigarette industry plan, and specifies that investment in heated tobacco products should be increased. The plan proposes to increase investment in the research and development of cigarette production technology and equipment, improve cigarette quality and production efficiency, and promote the development of the cigarette industry towards intelligence, greening, and high-end.

[0003] In the new type of heated tobacco pipe, a fastener needs to be accurately positioned and implanted to secure the heating element. Existing implantation technology uses a push rod. After the pipe is in place, there is a brief pause before the push rod pushes the fastener into the pipe. After the push rod retracts, the pipe continues to operate. This implantation method has the following problems: 1. Low work efficiency, unable to meet the higher requirements of new tobacco equipment. 2. The fastener is too short, and the push rod is prone to damaging the pipe, increasing the scrap rate and cost. 3. The push rod pressing down on the fastener can lead to inaccurate positioning. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of current firmware pressing methods, the present invention provides a flexible firmware pressing device in a flue, which can solve the problems of firmware pressing, improve production efficiency, meet the needs of automated high-speed production, reduce production costs, accurately position firmware, and solve quality problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: According to one aspect of the present invention, a flexible pressing and fitting device in a cigarette tube is provided, comprising a material introduction mechanism, a device body, and a cigarette turning and output structure; the material introduction mechanism is divided into a cigarette tube hopper and a fitting hopper; the device body is divided into a cigarette tube conveying structure, a fitting conveying structure, and a combined conveying structure; the cigarette tube hopper is connected to the cigarette tube conveying structure, and the fitting hopper is connected to the fitting conveying structure; the cigarette turning and output structure is connected to the end of the combined conveying structure; the cigarette tube conveying structure is sequentially provided with a connecting roller, a conveying roller, a flaring roller, and a transfer roller; the fitting conveying structure is sequentially provided with a picking roller, a misalignment roller, a combining roller, a second cutting roller, a second misalignment roller, a conveying roller, a second combining roller, and a transfer roller; the combined conveying structure is sequentially provided with a combining roller, a pressing roller, a transition roller, a final cutting roller, a separating roller, a conveying roller, a turning roller, and a conical turning structure; the cigarette turning and output structure is sequentially provided with a cigarette receiving roller, a turning roller, a conveying roller, and an output roller.

[0006] Optionally, a push rod is provided in the groove around the flaring wheel. The end of the push rod is tapered, and the axial movement of the push rod is controlled by a cam to flare the inlet of the flue.

[0007] Optionally, each groove around the pressing wheel is provided with a push rod, and multiple push rods are grouped together. They are connected to the cam surface through a cam connecting rod and rollers. The cam surface pushes the push rod to move axially, which is used to press the fastener into the smoke pipe.

[0008] Optionally, three disc-shaped cutters are provided around the pick-up wheel to cut the long strip of fastener into four segments.

[0009] Optionally, the misaligned wheel is used to arrange the four segments of the cut firmware in a state where the axes are parallel and misaligned.

[0010] Optionally, a disc cutter is provided around the second cutting wheel for cutting from the middle of each piece of firmware.

[0011] Optionally, a disc-shaped cutter is provided around the final cutting wheel for cutting from the middle position of the cigarette tube assembly that has been pressed into the fastener.

[0012] Optionally, the initial length of the firmware material in the firmware hopper is 16 times the actual length of the firmware in the product, and the initial length of the flue material in the flue hopper is twice the actual length of the flue in the product.

[0013] Optionally, the conical wheel turning structure is used to turn the outer row assembly around and place it in the middle position of the inner row assembly to form a single row output state.

[0014] Optionally, the steering wheel is a 90° conical wheel shape, installed at a 45° angle in space, used to change the assembly of the smoke receiving wheel output from a horizontal to a vertical state. The advantages of this invention are as follows: The use of a wheel-type transmission structure and press-fitting process enables high-speed operation of the product, meeting the high-speed automation requirements of equipment and significantly improving production efficiency compared to existing technologies. The multi-slitting principle, achieved through multiple slitting, misalignment, merging, and re-slitting of materials as they move between drums, forms ultra-short material aggregates, solving the problem of difficult transportation of ultra-short components in existing technologies. The use of a flaring and cam-pressing process, through a two-step process of flaring the flue inlet before press-fitting the components, achieves a high success rate and flexible continuous press-fitting, effectively solving the problem of flue damage, reducing product scrap rate, and lowering production costs compared to existing push-rod methods. The positioning device and positioning holes ensure accurate component positioning, effectively solving the quality problem of inaccurate component positioning compared to existing technologies.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1 This embodiment provides a flexible press-fit device for a cigarette tube, which includes three main parts: a material introduction mechanism, a device body, and a cigarette branch turning and output structure.

[0020] The material feeding mechanism consists of two independent hopper systems: a flue hopper and a fastener hopper. The flue hopper stores and supplies flue material, with an initial length twice the actual length of the flue material in the product. The fastener hopper stores and supplies fastener material, with an initial length 16 times the actual length of the fastener material in the product. This design ensures sufficient raw material length for subsequent multiple slitting and processing.

[0021] The main body of the equipment is the core processing part of the entire equipment, which includes three interconnected conveying systems: the smoke pipe conveying structure, the fastener conveying structure, and the combined conveying structure.

[0022] The flue pipe conveying structure is connected to the flue pipe hopper and is sequentially equipped with a connecting roller 1, a first conveying roller 2, a flaring roller 3, and a first transfer roller 4. The connecting roller 1 connects the flue pipe from the hopper into the groove around its circumference. The first conveying roller 2 moves the flue pipe into the groove around the flaring roller 3. A push rod is correspondingly positioned in the groove around the flaring roller 3; the push rod's end is tapered, and its axial movement is controlled by a cam. As the flaring roller 3 rotates, the push rod slowly moves axially towards the flue pipe. When the tapered end of the push rod moves a certain distance towards the flue pipe, it widens the flue pipe inlet to a certain extent, forming a flared angle, providing guidance for the subsequent pressing of the fittings and preventing damage to the flue pipe during pressing. The first transfer roller 4 transports the flared flue pipe to the combined conveying structure.

[0023] The firmware conveying structure is connected to the firmware hopper and includes, in sequence, a picking wheel 6, a staggered wheel 7, a converging wheel 8, a second cutting wheel 9, a second staggered wheel 10, a conveyor wheel, a second converging wheel 12, and a second transfer wheel 13. The picking wheel 6 uses grooves around its perimeter to receive firmware from the hopper into these grooves. Three disc-shaped cutters around the picking wheel 6 cut long firmware strips into four segments, enabling the transport of ultra-short firmware. The staggered wheel 7 arranges the four segments in a parallel, offset configuration to prevent interference between firmware. The converging wheel 8 uses negative pressure and airflow to move the firmware axially, creating a row of output firmware. The second cutting wheel 9 has a disc-shaped cutter around its perimeter to cut each segment in half from the middle. The second staggered wheel 10 arranges the two separated segments concentrically in a parallel, offset configuration. The conveyor wheel transports the processed firmware to the second converging wheel 12. The second converging wheel 12 uses negative pressure and airflow to move the firmware axially, forming a row of firmware status outputs. The second transfer wheel 13 transports the finally processed firmware to the combined conveyor structure.

[0024] The assembly conveyor structure is sequentially configured with a general assembly wheel 5, a pressing wheel 14, a transition wheel 15, a final cutting wheel 16, a separating wheel 17, a second conveyor wheel 18, a turning wheel 19, and a conical wheel turning structure. The general assembly wheel 5 receives the flue pipes and components from the flue pipe conveyor structure and the component conveyor structure, arranging them side-by-side in the grooves around the wheel. Each groove around the pressing wheel 14 corresponds to a push rod, with multiple push rods forming a group. These push rods contact the cam surface via a cam connecting rod and rollers, and the cam surface pushes the push rods to move axially. As the pressing wheel 14 rotates, the cam surface pushes the push rods axially, slowly pushing each component into the middle of the flue pipe, and then slowly withdrawing it through the curved surface, achieving flexible continuous pressing and assembly, so that each flue pipe and component is combined into one unit. The transition wheel 15 conveys the assembly to the final cutting wheel 16. A disc-shaped cutter is positioned around the final cutting wheel 16 to cut the cigarette tube assembly from the middle of the pressed-in fastener, dividing the assembly into two equal sections, resulting in symmetrical placement of the products at both ends. The separating wheel 17, controlled by an internal cam, separates the outer assembly outwards, while the inner assembly remains stationary axially. The second conveyor wheel 18 transports the two-sectioned assembly to the turning wheel 19. The number of grooves on the inner surface of the turning wheel 19 is twice the number on the outer surface. The conical turning mechanism is used to turn the outer assembly around and place it in the middle of the inner assembly, creating a single-row output configuration, ensuring the cut assemblies are output in a single row.

[0025] The cigarette-turning output structure is connected to the end of the combined conveying structure, and is sequentially equipped with a receiving wheel 21, a turning wheel 22, a third conveying wheel 23, and an output wheel 24. The receiving wheel 21 receives the assembly output from the turning wheel 19 and transmits it to the turning wheel 22. The turning wheel 22 is a 90° conical wheel, installed at a 45° angle in space, used to turn the assembly output from the receiving wheel 21 from a horizontal to a vertical position. The third conveying wheel 23 conveys the turned assembly. The output wheel 24 outputs the final product to the next process.

[0026] This equipment employs a wheel-type transmission structure and a novel process route, achieving the transportation of ultra-short components through a multi-splitting principle. It utilizes flaring and cam-pressing processes to improve pressing success rates and ensure flexible, continuous pressing, thus resolving damage to the flue tubes and reducing product scrap rates. The entire equipment can operate at high speeds, meeting the demands of high-speed automation, ultimately outputting flue streams arranged in a single direction.

[0027] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
