Description

Technical Field

[0001] This utility model relates to a mosquito coil packaging machine, and more particularly to an automatic mosquito coil feeding system, belonging to the technical field of automated mosquito coil processing equipment. Background Technology

[0002] A mosquito coil packing machine is an automated device specifically designed to pack mosquito coil products (mainly designed for disc-type mosquito coil tablets) into cylindrical packages and seal them. Its design aims to improve packaging efficiency, reduce labor costs, and ensure the airtightness and aesthetics of the products during transportation and storage.

[0003] For small-box packaging, mosquito coils are typically fed into the equipment via a vibrating disc or conveyor belt. Sensors or a vision system position them to ensure precise alignment. The coils are then pushed into pre-made cylindrical packaging materials (such as PVC or OPP cylinders) to complete the tube-filling process. For large-box packaging, several trays (usually five coils, totaling ten trays) of mosquito coil tablets are first packaged into mosquito coil pouches, and then the coils are packed into mosquito coil tubes.

[0004] In existing technologies, the process of packing mosquito coils into coil containers is typically done manually, resulting in low efficiency and difficulty in guaranteeing quality. Some devices use sponge suction cups for automatic coil packing; however, the unpredictable shape of the coil packaging makes it prone to empty gripping during the suction process, and the process itself can easily damage the coils, leading to quality issues. With the accelerating trend towards automation in mosquito coil production, the low efficiency and high waste of traditional manual packing methods have become increasingly apparent, creating a strong demand for automated equipment. Export-oriented companies are demanding higher standards for packaging aesthetics and standardization, driving market growth for high-end packing equipment. Existing mosquito coil packaging equipment is increasingly failing to meet market demands, creating an urgent need for fully automated mosquito coil packaging equipment to improve production efficiency and solve bottlenecks in production. Summary of the Invention

The mosquito coil bag feeding conveyor belt 22, the mosquito coil tube feeding conveyor belt 27, the positioning workbench 216, and the discharging conveyor belt 220 are respectively installed on the support platform 21. The positioning mechanism is installed on the positioning workbench 216. The feeding push mechanism is set corresponding to the mosquito coil tube feeding conveyor belt 27.

[0036] In this embodiment, the mosquito coil tube feeding conveyor belt 27 is used to feed the mosquito coil tube 4. A mosquito coil tube feeding motor 28 is correspondingly provided to the mosquito coil tube feeding conveyor belt 27, which can drive the mosquito coil tube feeding conveyor belt 27 to move. The connection between the mosquito coil tube feeding motor 28 and the mosquito coil tube feeding conveyor belt 27 is not the focus of this utility model; a conventional driving method can be used. In this embodiment, the mosquito coil tube feeding conveyor belt 27 is annular, and the annular mosquito coil tube feeding conveyor belt 27 is hooked onto the mosquito coil tube feeding drive wheel (…). Between the mosquito coil feeding drive wheel (not shown in the figure) and the mosquito coil tube feeding driven wheel (not shown in the figure), the mosquito coil tube feeding drive wheel and the mosquito coil tube feeding driven wheel are arranged in parallel. The mosquito coil tube feeding motor 28 is connected to the mosquito coil tube feeding drive wheel. The mosquito coil tube feeding motor 28 and the mosquito coil tube feeding drive wheel can be connected by a coupling, gearbox, or belt, etc., as long as the mosquito coil tube feeding motor 28 can drive the mosquito coil tube feeding conveyor belt 27 to move. In this embodiment, the mosquito coil tube feeding motor 28 and the mosquito coil tube feeding drive wheel are connected by gears. In this embodiment, the mosquito coil tube feeding conveyor belt 27 and the mosquito coil tube feeding motor 28 are respectively mounted on the mosquito coil tube feeding bracket (not shown in the figure), and the mosquito coil tube feeding bracket is fixedly mounted on the support platform 21.

[0037] In this embodiment, the feeding and pushing mechanism includes a feeding cylinder 29 and a feeding pusher 210. The feeding cylinder 29 is fixedly mounted on the support platform 21 via a feeding cylinder mounting bracket (not shown in the figure). The feeding cylinder 29 is located on the side of the mosquito coil tube feeding conveyor belt 27. The feeding pusher 210 is fixedly mounted together with the air rod of the feeding cylinder 29. The feeding cylinder 29 can drive the feeding pusher 210 to move back and forth. In this embodiment, the end face of the feeding pusher 210 is arc-shaped, which allows it to fit more closely to the mosquito coil tube 4 and can play a guiding role during the pushing process. In this embodiment, the feeding and pushing mechanism is provided in two sets, which can feed two sets of mosquito coil tubes simultaneously. Both sets of feeding and pushing mechanisms are equipped with detectors 212. The detectors 212 can be reflective fiber optic sensors used to detect whether there are mosquito coil tubes on the mosquito coil tube feeding conveyor belt 27. The detectors 212 are mounted on the mosquito coil tube feeding bracket via detector brackets 211. A baffle 214 is provided behind the second feeding mechanism (in this invention, the direction of movement of the mosquito coil tube is defined as front to back). The baffle 214 is positioned above the mosquito coil tube feeding conveyor belt 27 and can be used to block the mosquito coil tubes being transported on the conveyor belt 27. The baffle 214 is mounted on a rotary cylinder 213, which is fixedly mounted on the mosquito coil tube feeding bracket. The baffle 214 can be driven to swing by the rotary cylinder 213, thereby achieving the desired movement. The mosquito coils on the mosquito coil feeding conveyor belt 27 are blocked or released. When a large number of mosquito coils accumulate on the conveyor belt 27 and cannot be processed in time, or when other equipment malfunctions and it is necessary to clear the mosquito coils from the conveyor belt 27, the baffle 214 is rotated to release the conveyor belt 27, allowing the mosquito coils 4 on the conveyor belt 27 to be discharged along the conveyor belt 27. Under normal conditions, the baffle 214 blocks the mosquito coil feeding conveyor belt 27. In this embodiment, a discharge cylinder 215 is installed behind the baffle 214. The discharge cylinder 215 is fixedly installed on the mosquito coil feeding bracket. When a defective mosquito coil 4 is found on the conveyor belt 27 in the previous process, the discharge cylinder 215 is activated to push the corresponding mosquito coil away from the conveyor belt 27.

[0038] In this embodiment, mosquito coil tube feeding baffles are fixedly installed on both sides of the mosquito coil tube feeding bracket to block the mosquito coil tube 4 on the mosquito coil tube feeding conveyor belt 27 so that it will not fall off from the side. The mosquito coil tube feeding baffles on both sides of the mosquito coil tube feeding bracket are provided with notches corresponding to the position of the feeding cylinder 29, which can be used for the feeding push head 210 and the mosquito coil tube 4 to pass through.

[0039] In this embodiment, two sets of positioning mechanisms are provided, each corresponding to one set of feeding and pushing mechanisms. The two sets of positioning mechanisms are fixedly installed on the positioning worktable 216. Each set of positioning mechanisms includes two positioning cylinders 217 and two sets of positioning plates. The positioning cylinders 217 are fixedly installed on the positioning worktable 216, and the two positioning cylinders 217 are arranged opposite each other. Each set of positioning cylinders 217 has a set of positioning plates installed on it. The positioning plates can be moved by the positioning cylinders 217 to achieve clamping and positioning of the mosquito coil tube 4. In this embodiment, the opposing surfaces of the two sets of positioning plates are arc-shaped, preferably matching the outer surface of the mosquito coil tube 4, to achieve precise positioning. In this embodiment, each set of positioning plates has two plates: a lower positioning plate 218 and an upper positioning plate 219. The lower positioning plate 218 is fixedly installed on the positioning cylinder 217, and the upper positioning plate 219 is fixedly positioned above the lower positioning plate 218.

[0040] In this embodiment, the feeding conveyor belt 220 is used to feed the mosquito coil tube containing the mosquito coil sachet. A feeding motor 221 is provided corresponding to the feeding conveyor belt 220, which can drive the feeding conveyor belt 220 to move. The connection between the feeding motor 221 and the feeding conveyor belt 220 is not the focus of this utility model, and a conventional driving method can be used. In this embodiment, the feeding conveyor belt 220 is ring-shaped and is connected between the feeding drive wheel (not shown in the figure) and the feeding driven wheel (not shown in the figure). The feeding drive wheel and the feeding driven wheel are arranged in parallel. The feeding motor 221 is connected to the feeding drive wheel. The feeding motor 221 and the feeding drive wheel can be connected by a coupling, gearbox, or belt, etc., as long as the feeding motor 221 can drive the feeding conveyor belt 220 to move. In this embodiment, the feeding motor 221 and the feeding drive wheel are connected by gears. In this embodiment, the feeding motor 221 and the feeding conveyor belt 220 are respectively installed on the feeding bracket (not shown in the figure). The feeding bracket is fixedly installed on the support platform 21. The mosquito coil tube 4 that has been transferred into the mosquito coil bag can be transported away by the feeding conveyor belt 220 and sent to the next process.

[0041] In this embodiment, the mosquito coil feeding conveyor belt 22 is used to feed mosquito coils. A mosquito coil feeding motor 23 is correspondingly provided to the mosquito coil feeding conveyor belt 22, which can drive the mosquito coil feeding conveyor belt 22 to move. The connection between the mosquito coil feeding motor 23 and the mosquito coil feeding conveyor belt 22 is not the focus of this utility model; a conventional driving method can be used. In this embodiment, the mosquito coil feeding conveyor belt 22 is annular, and the annular mosquito coil feeding conveyor belt 22 is hooked onto the mosquito coil feeding drive wheel (…). Between the mosquito coil feeding drive wheel (not shown in the figure) and the mosquito coil feeding driven wheel (not shown in the figure), the mosquito coil feeding drive wheel and the mosquito coil feeding driven wheel are arranged in parallel. The mosquito coil feeding motor 23 is connected to the mosquito coil feeding drive wheel. The mosquito coil feeding motor 23 and the mosquito coil feeding drive wheel can be connected by a coupling, gearbox, or belt, etc., as long as the mosquito coil feeding motor 23 can drive the mosquito coil feeding conveyor belt 22 to move. In this embodiment, the mosquito coil feeding motor 23 and the mosquito coil feeding drive wheel are connected by gears. In this embodiment, the mosquito coil feeding motor 23 and the mosquito coil feeding conveyor belt 22 are respectively installed on the mosquito coil feeding bracket (not shown in the figure), and the mosquito coil feeding bracket is fixedly installed on the support platform 21. In this embodiment, a conveyor belt gantry 24 is fixedly installed above the front end of the mosquito coil feeding bracket.

The height of the limit opening can be equal to or slightly greater than the height of the mosquito coil bag (in this embodiment, "slightly greater than" means less than the height of two mosquito coil bags stacked together). If the mosquito coil bags are stacked during the conveying process, the limit cover 26 can block the upper mosquito coil bag, allowing it to fall naturally onto the mosquito coil bag feeding conveyor belt 22 behind.

[0042] In this embodiment, the clamping and feeding mechanism 3 is mainly used to clamp the heat-sealed mosquito coil bag and place it into the mosquito coil packaging tube.

When the mosquito coil tube 4 is transported to the set position, it is pushed onto the positioning worktable 216 by the feeding pusher 210, and then the mosquito coil tube is positioned by the positioning mechanism. When the mosquito coil sachet is transported to the set position by the mosquito coil sachet feeding conveyor belt 22, the first drive motor 32, the second drive motor 33, and the third drive motor 34 drive the corresponding drive rods to move. The drive rods drive the driven rods to move, and the driven rods drive the clamping device 319 to move above the mosquito coil sachet. All components are connected via a universal ball joint and a universal ball sleeve. Under its own weight, the clamping device 319 always faces downward. When it moves above the designated mosquito coil bag, the clamping device 319 moves downward. When the trigger baffle 326 touches the mosquito coil bag, it pushes the trigger switch 325 to trigger. The trigger switch 325 controls the four cylinders 321 on the clamping device 319, which push the corresponding clamping plates 323 to clamp the mosquito coil bag and place it into the corresponding mosquito coil tube 4. After the mosquito coil bag is placed in the tube, the feeding pusher 210 continues to push the mosquito coil tube onto the unloading conveyor belt 220, which then sends it to the next process.

[0052] This invention employs a clamping and feeding mechanism combined with a mosquito coil tube loading and unloading structure, enabling fully automated operation by automatically grabbing mosquito coil packs from the conveyor belt and feeding them into the mosquito coil tubes. The coil tubes are then pushed back onto the conveyor belt for transport to the next stage of the process. This invention significantly improves packaging efficiency and quality through intelligent design, making it a key piece of equipment for mosquito coil manufacturers to achieve automation upgrades. In the future, with the integration of IoT technology, remote monitoring and predictive maintenance functions will become more widespread, driving the industry towards a higher level of development. Furthermore, this invention supports intelligent detection functions, such as material shortage shutdown and abnormal alarms, effectively reducing the defect rate.

[0053] This invention can operate at a stable and fast speed. Compared with manual feeding, it can greatly shorten the packaging time of a single mosquito coil, thereby improving the overall production efficiency and meeting the needs of large-scale production. Moreover, it has high precision and can accurately feed the mosquito coil into the packaging tube. The position is accurate and the coils are neatly arranged, reducing problems such as improper placement or tilting of mosquito coils that may occur due to manual operation, thus improving the consistency and quality stability of the packaging.

[0054] Meanwhile, this invention reduces the labor required for manual material feeding, lowering the company's labor costs. It also avoids the impact on production caused by personnel turnover and fatigue. Mosquito coil production may involve dust and odors; using this invention to replace manual operation allows workers to avoid harsh working environments, ensuring employee health and safety. Furthermore, precise control and adjustment through programming facilitate unified management and monitoring of the production process, enabling real-time recording and analysis of production data, which helps optimize production processes and improve management efficiency.
