Description

Technical Field

[0001] This utility model relates to the conveying mechanism of a mosquito coil barrel filling machine, and belongs to the technical field of mosquito coil packaging machines. Background Technology

[0002] After production and processing, mosquito coils are typically packaged in a tray using a moisture-proof film or bag to prevent surface moisture. The trays are then placed into mosquito coil containers, thus completing the packaging process. Traditionally, the trays are manually packed into containers. This manual method is labor-intensive, costly, and inefficient, making it unsuitable for automated production lines.

[0003] To achieve automated filling of mosquito coil packaging bags into barrels, a conveyor mechanism is needed to transport the packaging bags containing mosquito coils. Chinese invention patent application CN115959337A, entitled "An Automatic Incense Coil Barrel Filling Device," discloses an automatic incense coil barrel filling device, comprising a frame, on which an incense tray and a barrel tray are fixedly installed. The incense tray is located above the barrel tray and has an incense coil feeding port and an incense coil discharging hole. The barrel tray has a barrel feeding port and a barrel discharging port. The frame is also equipped with a feeding mechanism and a pressing mechanism driven by a drive device. The incense coil feeding mechanism is located at the incense coil feeding port on the frame, the barrel feeding mechanism is located at the barrel feeding port on the frame, the pressing mechanism is located at the corresponding position of the incense coil discharging hole, and the barrel discharging mechanism is located at the barrel discharging port on the frame. The incense coil feeding mechanism, the barrel feeding mechanism, the pressing mechanism, and the barrel discharging mechanism are arranged sequentially along the circumference of the frame.

[0004] Chinese invention patent application CN109515843A, entitled "An Automatic Mosquito Repellent Tablet Packing Machine," discloses an automatic mosquito repellent tablet packing machine, comprising a frame, a mosquito repellent conveyor belt, a paper drum conveyor belt, a lid conveyor belt, a finished product conveyor belt, a gripping mechanism, and a capping mechanism. The mosquito repellent conveyor belt, paper drum conveyor belt, lid conveyor belt, finished product conveyor belt, gripping mechanism, and capping mechanism are mounted on the frame. The paper drum conveyor belt, lid conveyor belt, and finished product conveyor belt are arranged in parallel. The mosquito repellent conveyor belt is located at the output end of the paper drum conveyor belt. A gripping mechanism for placing mosquito repellent tablets into the paper drum is provided between the mosquito repellent conveyor belt and the paper drum conveyor belt. The capping mechanism is located at the output end of the lid conveyor belt. A synchronous conveyor belt is provided below the capping mechanism and the gripping mechanism. A pusher mechanism is provided at the input end of the finished product conveyor belt.

[0005] The aforementioned conveying mechanisms for transporting mosquito coils all include a drive shaft, a driven shaft, a conveyor belt mounted on the drive shaft and driven shaft, and a power mechanism for driving the drive shaft to rotate. This type of conveying mechanism can only transport one packaging bag at a time, and then successively fill the packaging bags into the mosquito coil bucket (generally, 2 to 4 packaging bags can be stacked in one mosquito coil bucket), resulting in relatively low filling efficiency.

[0006] Based on the above issues, the applicant conducted research on these issues and thus this case came into being. Utility Model Content

[0007] The purpose of this invention is to provide a conveying mechanism for a mosquito coil barrel filling machine that can improve barrel filling efficiency.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] The conveying mechanism of the mosquito coil filling machine includes a support frame, a drive shaft mounted on the support frame, a driven shaft mounted on the support frame, a conveyor belt sleeved on the drive shaft and the driven shaft, and a power mechanism for driving the drive shaft to rotate. It also includes a gripping mechanism positioned above the travel path of the conveyor belt. The gripping mechanism has a gripping part capable of gripping mosquito coil packaging bags and a lifting mechanism for moving the gripping part up and down. The gripping part is positioned above the conveyor belt, and a stacking station is provided on the conveyor belt corresponding to the position of the gripping part. The machine also includes a material sensor for detecting whether there is material at the stacking station. When a mosquito coil packaging bag moves to the stacking station, the lifting mechanism drives the gripping part to grip the mosquito coil packaging bag upwards. When the next mosquito coil packaging bag moves to the stacking station, the gripping part releases the gripped mosquito coil packaging bag, causing the two mosquito coil packaging bags to be stacked together.

[0010] In a preferred embodiment of this utility model, the gripping part is a suction cup, with one end of the suction cup being the adsorption end and the other end connected to a vacuum device.

[0011] In a preferred embodiment of the present invention, the lifting mechanism includes a slide rail mounted on the bracket, a slider mounted on the slide rail, and a vertical drive mechanism for driving the slider to move up and down on the slide rail. The suction cup is connected to the slider via a connecting plate.

[0012] In a preferred embodiment of the present invention, the up-and-down driving mechanism includes a rack connected to the slider, a gear cooperating with the rack, and an up-and-down driving motor. The up-and-down driving motor is mounted on the bracket, and the gear is mounted on the output shaft of the up-and-down driving motor.

[0013] In a preferred embodiment of this invention, the gripping part is a gripping robotic arm.

[0014] As a preferred embodiment of this utility model, the conveyor belt has multiple partition plates on the conveyor surface for placing packaging bags, and the multiple partition plates are evenly arranged around the circumference of the conveyor belt.

[0015] In a preferred embodiment of this utility model, a drive shaft is passed through the center of the driven shaft, and the driven shaft is rotatably sleeved on the drive shaft. The drive shaft is connected to a drive motor for driving the drive shaft to rotate. A first drive ring and a second drive ring are installed on the drive shaft. The driven shaft is located between the first drive ring and the second drive ring. The bracket also includes a first driven ring and a second driven ring, and further includes a first receiving belt sleeved on the first drive ring and the first driven ring, and a second receiving belt sleeved on the second drive ring and the second driven ring. The distance between the first receiving belt and the second receiving belt is less than the width of the packaging bag.

[0016] As a preferred embodiment of the present invention, it further includes a material support plate disposed between the first receiving belt and the second receiving belt, and a first cylinder for driving the material support plate to move up and down.

[0017] As a preferred embodiment of the present invention, it further includes a baffle plate corresponding to the material support plate and a second cylinder for driving the baffle plate to move up and down, wherein the material support plate is disposed between the baffle plate and the driven shaft.

[0018] The technical solution of this utility model involves setting a gripping mechanism along the conveyor belt's travel path. Packaging bags are conveyed to the area below the gripping mechanism via the conveyor belt. A lifting mechanism drives the gripping part downwards to grasp the packaging bag, which in turn lifts the bag upwards. The conveyor belt continues to transport the packaging bags. When the next packaging bag moves to the area below the gripping mechanism, the lifting mechanism drives the gripping part downwards, releasing the already grasped bag onto the bag below, thus stacking the two bags together. In subsequent processes, the two stacked bags can be placed together into the mosquito coil container, improving the efficiency of mosquito coil filling. This utility model has the advantage of simple structure. Preferably, this utility model includes a first receiving belt and a second receiving belt, using a support plate to lift the packaging bag, keeping it stationary and facilitating its placement into the mosquito coil container in subsequent processes.

[0038] To better understand the technical solution of this utility model, the following description is provided in more detail with reference to the embodiments.

[0039] Reference Figures 1 to 3The conveying mechanism of the mosquito coil filling machine includes a support 100, a drive shaft 11 mounted on the support 100, a driven shaft 12 mounted on the support 100, a conveyor belt 13 sleeved on the drive shaft 11 and the driven shaft 12, and a power mechanism 10 for driving the drive shaft 11 to rotate. The drive shaft 11 and the driven shaft 12 are arranged in parallel and both are horizontal. This invention also includes a gripping mechanism positioned above the travel path of the conveyor belt 13. The gripping mechanism has a gripping part capable of gripping mosquito coil packaging bags and a lifting mechanism for moving the gripping part up and down. The gripping part is positioned above the conveyor belt 13. In this invention, the power mechanism 10 uses a motor, which can directly or indirectly transmit power to the drive shaft 11, thereby driving the drive shaft 11 to rotate. A stacking station is provided on the conveyor belt 13 corresponding to the position of the gripping part, and a material sensor 40 is also included for detecting whether there is material at the stacking station. The material sensor 40 is a conventional component in the field of electronic control. The material sensor 40 is connected to the controller mentioned above. When it detects that there is a packaging bag at the stacking station, the conveyor belt 13 stops conveying or the gripping mechanism sucks up or releases the mosquito coil bag, and then the conveyor belt continues to convey.

[0040] In a preferred embodiment of this invention, the gripping part is a suction cup 30, with one end of the suction cup 30 serving as the adsorption end and the other end connected to a vacuum device (not shown in the figure). The vacuum device creates a negative pressure at the adsorption end, thereby generating an adsorption force to adhere to the packaging bag. The use of a suction cup 30 to grip the packaging bag is a well-known technique in the art, and its structure will not be described in detail here.

[0041] In a preferred embodiment of this invention, the lifting mechanism includes a slide rail 34 mounted on the bracket 100, a slider 32 mounted on the slide rail 34, and a vertical drive mechanism for driving the slider 32 to move up and down on the slide rail. A groove 33 is provided on the slider 32, and the slide rail 34 fits into the groove 33. The suction cup 30 is connected to the slider 32 via a connecting plate 31. In this embodiment, the connecting plate 31 is arranged horizontally. In this invention, the power mechanism 10, the lifting mechanism, and the vacuum device, among other control mechanisms, can be coordinated and controlled by a controller to achieve coordinated operation of each mechanism.

[0042] As a preferred embodiment of the present invention, the up-and-down driving mechanism includes a rack 35 connected to the slider 32, a gear 36 cooperating with the rack 35, and an up-and-down driving motor 37. The up-and-down driving motor 37 is mounted on the bracket 100, and the gear 36 is mounted on the output shaft of the up-and-down driving motor 37. When the up-and-down driving motor 37 is started, the gear 36 rotates on the rack 35, thereby causing the rack 35 and the slider 32 to move up and down.

[0043] In another embodiment of this utility model, the gripping part can also be a gripping robot arm, which can be used to clamp and release the packaging bag.

[0044] In a preferred embodiment of this invention, the conveyor belt 13 has multiple partition plates 14 on its conveyor surface for placing packaging bags. These partition plates 14 are evenly arranged around the circumference of the conveyor belt 13. The partition plates 14 prevent the packaging bags from shifting during the conveyor belt 13's transport process.

[0045] In a preferred embodiment of this utility model, a drive shaft 27 is passed through the center of the driven shaft 12, and the driven shaft 12 is rotatably sleeved on the drive shaft 27. The drive shaft 27 is connected to a drive motor 20 for driving the drive shaft 27 to rotate. A first drive ring 21 and a second drive ring 22 are mounted on the drive shaft 27. In the embodiment, the first drive ring 21 and the second drive ring 22 are mounted on the drive shaft 27 in a manner that prevents them from rotating relative to the drive shaft 27. The driven shaft 12 is located between the first drive ring 21 and the second drive ring 22. A first driven ring 23 and a second driven ring 24 are also provided on the bracket 100, and the first driven ring 23 and the second driven ring 24 are rotatably mounted on the bracket 100. This utility model also includes a first receiving belt 25 sleeved on the first driving ring 21 and the first driven ring 23, and a second receiving belt 26 sleeved on the second driving ring 22 and the second driven ring 24. The first receiving belt 25 and the second receiving belt 26 are arranged in parallel, and the distance between the first receiving belt 25 and the second receiving belt 26 is less than the width of the packaging bag. Thus, after the packaging bag is conveyed by the first receiving belt 25 and the second receiving belt 26, it can be conveyed by the first receiving belt 25 and the second receiving belt 26 together.

[0046] As a preferred embodiment of the present invention, it further includes a material support plate 50 disposed between the first receiving belt 25 and the second receiving belt 26, and a first cylinder 51 for driving the material support plate 50 to move up and down. The cylinder body of the first cylinder 51 is mounted on the bracket 100, and the piston rod is connected to the material support plate 50.

[0047] As a preferred embodiment of this utility model, it further includes a baffle plate 60 corresponding to the material support plate 50 and a second cylinder 61 for driving the baffle plate 60 to move up and down. The material support plate 50 is disposed between the baffle plate 60 and the driven shaft 12. The cylinder body of the second cylinder 61 is connected to the bracket 100, and the piston rod of the second cylinder 61 is connected to the baffle plate 60. By setting the baffle plate 60, the packaging bag can be prevented from sliding off the ends of the first receiving belt 25 and the second receiving belt 26.

[0048] In operation, the packaging bag (containing a mosquito coil) is fed into the conveyor belt 13. The conveyor belt 13 transports the packaging bag to the material sensor 40. The material sensor 40 receives a signal, the conveyor belt 13 stops moving, and the suction cup 30 moves downward under the action of the lifting mechanism to pick up the packaging bag. After that, the packaging bag rises a certain distance, the material sensor 40 receives a signal and the signal disappears, the conveyor belt 13 continues to transport forward, the next packaging bag moves to the material sensor 40, the material sensor 40 receives a signal, the conveyor belt 13 stops moving, the lifting mechanism drives the suction cup 30 to descend, releasing the packaging bag that has been picked up by the suction cup 30, so that there are two packaging bags at the stacking station. The conveyor belt 13 sends the two packaging bags into the first receiving belt 25 and the second receiving belt 26. At this time, the first receiving belt 25 and the second receiving belt 26 transport the stacked packaging bags to the material support plate 50. The baffle plate 60 rises to prevent the packaging bags from slipping off from one end. The material tray is lifted to 50 liters, raising the two packaging bags together, and then transferring them into the mosquito coil bucket in the next process.

[0049] In the embodiments of this application, a gripping mechanism is provided to stack two packaging bags together, or two gripping mechanisms are provided and arranged along the conveyor belt conveyor direction, so that three packaging bags can be stacked.
