Description

Technical Field

[0001] This utility model belongs to the field of material sorting and return technology, and specifically relates to a mosquito coil ring sorting and return system. Background Technology

[0002] Mosquito coils (or disc-shaped mosquito coils) are a type of mosquito repellent product. Most of them are manufactured using traditional manual methods or semi-automated equipment. Otherwise, it is difficult to control costs. In the conventional production process, after the mosquito coils are produced and processed, a certain number of mosquito coils are usually stacked up and then manually sent to the subsequent material handling or packaging mechanism.

[0003] Currently, conventional methods often require workers to place stacked mosquito coil rings onto the conveyor lines of the feeding or packaging mechanisms. If there are multiple production lines for mosquito coil rings, multiple workers are needed, resulting in high labor costs, high labor intensity for workers, and difficulty in guaranteeing work efficiency. Later, simple automatic conveying methods emerged, such as using a single conveyor belt to continuously and automatically transport stacked mosquito coil rings. However, each conveyor belt can only correspond to one corresponding mechanism, which has significant limitations and a low level of automation. It is still difficult to adapt to mosquito coil machine production lines composed of multiple feeding mechanisms or multiple packaging machines, and therefore cannot meet the high-efficiency production needs of enterprises.

[0004] In view of this, the applicant conducted in-depth research on the above-mentioned issues, which led to the occurrence of this case. Utility Model Content

[0005] The purpose of this invention is to provide a highly automated mosquito coil ring sorting and return system that can be adapted to mosquito coil machine production lines.

[0006] To achieve the above objectives, this utility model adopts the following technical solution:

[0007] A mosquito coil sorting and return system includes a frame, on which are mounted a first conveyor belt and a second conveyor belt for conveying mosquito coils, and a return conveyor belt located between the first and second conveyor belts. The first and second conveyor belts each have multiple discharge ports on their sides away from the return conveyor belt. The frame is equipped with multiple unloading mechanisms for pushing mosquito coils on the first or second conveyor belt to the corresponding discharge ports. The first and second conveyor belts have opposite conveying directions to the return conveyor belt, and the inlet end of the return conveyor belt is connected to the first conveyor belt. The outlet end of the return conveyor belt is connected to the inlet end of the first conveyor belt and the second conveyor belt. The outlet ends of the first conveyor belt and the second conveyor belt are both provided with return baffles. The outlet end of the return conveyor belt is provided with a diversion baffle. The frame is provided with a return pushing mechanism for pushing mosquito coil rings on the first conveyor belt or the second conveyor belt to the return conveyor belt at the position corresponding to the inlet end of the return conveyor belt. The frame is provided with a diversion pushing mechanism for pushing mosquito coil rings to the first conveyor belt or the second conveyor belt at the position corresponding to the outlet end of the return conveyor belt.

[0008] It also includes a main control terminal for controlling the first conveyor belt conveying, controlling the second conveyor belt conveying, controlling the return conveyor belt conveying, controlling the operation of the unloading mechanism, controlling the operation of the return pushing mechanism, and controlling the operation of the diversion pushing mechanism.

[0009] Furthermore, the return push mechanism includes a first sensor disposed at the outlet end of the first conveyor belt, a second sensor disposed at the outlet end of the second conveyor belt, a first push component disposed above the outlet end of the first conveyor belt, a second push component disposed above the outlet end of the second conveyor belt, and a first lateral drive mechanism for moving the first push component and the second push component.

[0010] Furthermore, the reflux pushing mechanism also includes a third sensor disposed above the inlet end of the reflux conveyor belt.

[0011] Furthermore, the diversion and pushing mechanism includes a fourth sensor disposed on the frame near the outlet end of the return conveyor belt, a fifth sensor disposed on the outlet end of the return conveyor belt, a third pushing component disposed above the outlet end of the return conveyor belt, and a second traverse drive mechanism for moving the third pushing component.

[0012] Furthermore, the feeding mechanism includes a first feeding sensor and a second feeding sensor spaced apart on the frame, and a feeding push component for pushing the mosquito coil rings on the first conveyor belt or the second conveyor belt to the corresponding discharge port. The first feeding sensor, the second feeding sensor, and the feeding push component are all arranged sequentially along the conveying direction of the corresponding first conveyor belt or the second conveyor belt.

[0013] Furthermore, the frame is provided with a support plate corresponding to the discharge port, the outlet of the support plate is provided with a discharge baffle, and a discharge sensor is provided above the discharge baffle.

[0014] Furthermore, the feeding mechanism also includes a blockage sensor disposed above the support plate, the blockage sensor being located on the support plate near the discharge port.

[0015] Furthermore, the frame is also provided with a sensing mechanism for sensing whether there are mosquito coil rings on the first conveyor belt or the second conveyor belt. The sensing mechanism is located at the inlet end of the first conveyor belt and the second conveyor belt near the outlet end of the return conveyor belt.

[0016] Furthermore, the first pushing component includes a vertically arranged first pushing cylinder and a first push plate fixed to the output end of the first pushing cylinder, and the second pushing component includes a vertically arranged second pushing cylinder and a second push plate fixed to the output end of the second pushing cylinder, with the output ends of both the first pushing cylinder and the second pushing cylinder arranged downwards.

[0017] Furthermore, the feeding and pushing assembly includes a horizontally arranged feeding cylinder, a feeding push plate fixed to the output end of the feeding cylinder, and a fixing plate fixed to the frame for mounting the feeding cylinder, wherein the output end of the feeding cylinder is arranged in the direction of the corresponding discharge port.

[0018] By adopting the aforementioned design scheme, the beneficial effects of this utility model are:

[0019] This utility model discloses a mosquito coil ring sorting and return system. It features a first conveyor belt, a second conveyor belt, and a third conveyor belt on a frame. Multiple feeding mechanisms push mosquito coil rings from the first or second conveyor belt to their corresponding discharge ports, continuously supplying mosquito coil rings to the corresponding sorting or packaging mechanisms at each discharge port. A return pushing mechanism on the frame pushes the mosquito coil rings from the first or second conveyor belt onto a return conveyor belt, and a diversion pushing mechanism pushes the mosquito coil rings from the return conveyor belt onto the first or second conveyor belt, achieving a cyclical return conveying effect. This system is highly automated and adaptable to mosquito coil machine production lines consisting of multiple sorting mechanisms or multiple packaging machines, meeting the high-efficiency production needs of enterprises.

[0020] Furthermore, the installation of a third sensor can prevent the mosquito coil ring from being damaged by collision due to material jamming at the inlet end of the return conveyor belt caused by the first and second push cylinders feeding material onto the return conveyor belt again.

[0021] Furthermore, a sensing mechanism is provided to prevent the third pusher from pushing the mosquito coil ring on the outlet end of the return conveyor belt into contact with the mosquito coil ring normally conveyed on the first or second conveyor belt, thus avoiding damage to the mosquito coil ring from collision.

[0056] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0057] like Figures 1 to 5 As shown, a mosquito coil sorting and return system includes a frame 100. The frame 100 is equipped with a first conveyor belt 1 and a second conveyor belt 2 for conveying mosquito coils, and a return conveyor belt 3 located between the first conveyor belt 1 and the second conveyor belt 2. The first conveyor belt 1, the second conveyor belt 2, and the return conveyor belt 3 are all horizontally arranged. Multiple discharge ports 10 are respectively provided on the side of the first conveyor belt 1 and the second conveyor belt 2 away from the return conveyor belt 3. The frame 100 is equipped with multiple discharge ports for pushing mosquito coils on the first conveyor belt 1 or the second conveyor belt 2 to the corresponding discharge ports. The feeding mechanism 4 of port 10 has a first conveyor belt 1 and a second conveyor belt 2 that are in the opposite direction to the return conveyor belt 3. The two sides of the inlet end of the return conveyor belt 3 are respectively connected to the outlet end of the first conveyor belt 1 and the outlet end of the second conveyor belt 2. The two sides of the outlet end of the return conveyor belt 3 are respectively connected to the inlet end of the first conveyor belt 1 and the inlet end of the second conveyor belt 2. The outlet end of the first conveyor belt 1 is provided with a first return baffle 201, the outlet end of the second conveyor belt 2 is provided with a second return baffle 202, and the outlet end of the return conveyor belt 3 is provided with a diversion baffle 30.

[0058] It should be noted that each discharge port 10 on the first conveyor belt 1 and the second conveyor belt 2 of this utility model corresponds to the inlet of the subsequent material handling mechanism (not shown in the figure) or packaging mechanism (not shown in the figure); when opened, the mosquito coil rings are conveyed from the inlet end of the first conveyor belt 1 and the outlet end of the second conveyor belt 2 to the outlet end respectively. When the mosquito coil rings pass through each feeding mechanism 4, the feeding mechanism 4 pushes the mosquito coil rings on the first conveyor belt 1 or the second conveyor belt 2 to the corresponding discharge port 10. The excess mosquito coil rings that are not pushed by the feeding mechanism 4 are blocked by the first return baffle 201 when they are conveyed to the outlet end of the first conveyor belt 1, and the excess mosquito coil rings are blocked by the second return baffle 202 when they are conveyed to the outlet end of the second conveyor belt 2. Correspondingly, the outlet ends of the first conveyor belt 1 and the second conveyor belt 2 correspond to the return baffle 202. At the inlet end of the return conveyor belt 3, the frame 100 is provided with a return pushing mechanism 5 for pushing mosquito coils on the first conveyor belt 1 or the second conveyor belt 2 to the return conveyor belt 3. At the outlet end of the return conveyor belt 3, the frame 100 is provided with a diversion pushing mechanism 6 for pushing mosquito coils on the first conveyor belt 1 or the second conveyor belt 2. The return pushing mechanism 5 pushes the excess mosquito coils on the first conveyor belt 1 or the second conveyor belt 2 to the middle return conveyor belt 3, and then conveys them from the inlet end of the return conveyor belt 3 to the outlet end. Then, the diversion pushing mechanism 6 pushes the mosquito coils at the outlet end of the return conveyor belt 3 back to the outlet end of the first conveyor belt 1 or the second conveyor belt 2 for re-conveyoring, so as to achieve the effect of such cyclical return conveying.

[0059] This utility model also includes a main control terminal for controlling the conveying of the first conveyor belt 1, the conveying of the second conveyor belt 2, the conveying of the return conveyor belt 3, the operation of the unloading mechanism 4, the operation of the return pushing mechanism 5, and the operation of the diversion pushing mechanism 6. It should be noted that the main control terminal of this utility model can be a conventional control system in the field, such as a single-chip microcomputer.

[0060] The return push mechanism 5 includes a first sensor 51 disposed at the outlet end of the first conveyor belt 1, a second sensor 52 disposed at the outlet end of the second conveyor belt 2, a first push component 53 disposed above the outlet end of the first conveyor belt 1, a second push component 54 disposed above the outlet end of the second conveyor belt 2, and a first lateral drive mechanism 55 for moving the first push component 53 and the second push component 54; specifically, the first sensor 51 is fixed on the first return baffle 201 at the outlet end of the first conveyor belt 1 and is used to detect whether there is a mosquito coil ring at the outlet end of the first conveyor belt 1, and the second sensor 52 is fixed on the second return baffle 202 at the outlet end of the second conveyor belt 2 and is used to detect whether there is a mosquito coil ring at the outlet end of the second conveyor belt 2.

[0061] Preferred, such as Figure 2 and Figure 5 As shown, the first transverse drive mechanism 55 includes a first mounting plate 551 arranged horizontally, a transverse slide rail 552 fixed on the first mounting plate 551, a pulley assembly 553 disposed below the transverse slide rail 552, a drive motor 554 for driving the pulley assembly 553 to reciprocate, and a first slide block 555 and a second slide block 556 spaced apart on the transverse slide rail 552; specifically, the arrangement direction of the first mounting plate 551 is perpendicular to the arrangement direction of the first conveyor belt 1, and the first mounting plate The two ends of 551 in the length direction correspond to the outlet ends of the first conveyor belt 1 and the second conveyor belt 2, respectively. The middle parts of the first slide block 555 and the second slide block 556 are slidably mounted on the transverse slide rail 552. The pulley assembly 553 can adopt a conventional pulley structure, that is, the pulley assembly 553 includes a driving pulley 501 in the middle, driven pulleys 502 located at both ends of the length direction of the first mounting plate 551, a number of rotating pulleys 503 located on both sides of the driving pulley 501, and a pulley system wound around the driven pulleys 502 and the driving pulley 501. The belt on the drive wheel 501 connects the drive wheel 501 to the output end of the drive motor 554. The transverse slide rail 552 and the belt are both arranged along the length of the first mounting plate 551. The bottoms of the first slide block 555 and the second slide block 556 are both fixed on the belt. Correspondingly, the first push component 53 is fixed on the first slide block 555, and the second push component 54 is fixed on the second slide block 556. The drive motor 554 can be a conventional servo motor capable of reciprocating rotation. In this embodiment, the distance between the first push component 53 and the second push component 54 needs to be reasonably set according to the actual situation to avoid one push component driving the other push component beyond the set distance of the transverse slide rail 552 when working. It should be noted that the first transverse drive mechanism 55 in this embodiment is not limited to the above structure. Other conventional transverse drive mechanisms in the art can also be used, as long as the above effect can be achieved. For example, two telescopic cylinders arranged opposite each other can be used to control the movement of the first push component 53 and the second push component 54 respectively.

[0062] Preferably, the first pushing assembly 53 includes a vertically arranged first pushing cylinder 531 and a first push plate 532 fixed to the output end of the first pushing cylinder 531. The second pushing assembly 54 includes a vertically arranged second pushing cylinder 541 and a second push plate 542 fixed to the output end of the second pushing cylinder 541. The output ends of both the first pushing cylinder 531 and the second pushing cylinder 541 are arranged downwards. When the first pushing cylinder 531 retracts, the first push plate 532 is located above the mosquito coil ring. When the first pushing cylinder 531 extends, the first push plate 532 is at the same horizontal height as the mosquito coil ring. When the second push cylinder 541 retracts, the second push plate 542 is located above the mosquito coil ring. When the second push cylinder 541 extends, the second push plate 542 and the mosquito coil ring are at the same horizontal height. The drive motor 554 reciprocates and rotates, driving the belt to rotate through the drive wheel 501, thereby driving the first slide block 555 and the second slide block 556 to reciprocate on the transverse slide rail 552, thereby driving the first push assembly 53 to push the mosquito coil ring on the first conveyor belt 1 from the outside to the inside onto the return conveyor belt 3, or driving the second push assembly 54 to push the mosquito coil ring on the second conveyor belt 2 from the outside to the inside onto the return conveyor belt 3.

[0063] Specifically, when the first sensor 51 detects a mosquito coil ring on the outlet end of the first conveyor belt 1, the drive motor 554 drives the belt to rotate, thereby moving the first slide block 555 and the first push cylinder 531 to the outside of the first conveyor belt 1. Then, the first push cylinder 531 extends, causing the first push plate 532 to extend to the same height as the mosquito coil ring, pushing the mosquito coil ring on the first conveyor belt 1 onto the return conveyor belt 3. After the pushing is completed, the first push cylinder 531 retracts to prevent it from touching the mosquito coil rings conveyed later during reciprocating movement. Similarly, when the second sensor 52 detects a mosquito coil ring on the outlet end of the second conveyor belt 2... The drive motor 554 drives the belt to rotate, thereby causing the second slide 556 and the second push cylinder 541 to move outward of the second conveyor belt 2 and perform the above-mentioned actions, pushing the mosquito coil ring on the second conveyor belt 2 onto the return conveyor belt 3. It should be noted that since the first slide 555 and the second slide 556 are fixed on the belt and move synchronously, when the first push cylinder 531 performs the pushing action, the second cylinder remains in a retracted state to avoid touching the mosquito coil ring on the second conveyor belt 2, and when the second push cylinder 541 performs the pushing action, the first cylinder remains in a retracted state to avoid touching the mosquito coil ring on the first conveyor belt 1.

[0064] Preferably, the return conveyor mechanism 5 also includes a third sensor 56 disposed above the inlet end of the return conveyor belt 3. Under normal circumstances, when the mosquito coil ring on the first conveyor belt 1 or the second conveyor belt 2 is pushed to the return conveyor belt 3, the main control terminal will control the return conveyor belt 3 to move a distance towards the outlet end so that the next mosquito coil ring can be sent into the return conveyor belt 3. When the third sensor 56 detects that there is a mosquito coil ring at the inlet end of the return conveyor belt 3, the first push cylinder 531 and the second push cylinder 541 will not extend, that is, they will not make a pushing action, so as to avoid the situation where the mosquito coil ring is damaged by collision due to the first push cylinder 531 and the second push cylinder 541 feeding material onto the return conveyor belt 3 again because the inlet end of the return conveyor belt 3 is jammed due to abnormal conditions.

[0065] like Figure 1 and Figure 4 As shown, the diversion and pushing mechanism 6 includes a fourth sensor 61 disposed on the frame 100 near the outlet end of the return conveyor belt 3, a fifth sensor 62 disposed on the outlet end of the return conveyor belt 3, a third pushing component 63 disposed above the outlet end of the return conveyor belt 3, and a second lateral drive mechanism 64 for driving the third pushing component 63 to move. The fifth sensor 62 is disposed on the diversion baffle 30.

[0066] The second lateral movement drive mechanism 64 includes a second mounting plate 641 arranged horizontally and a lead screw motor assembly fixed on the second mounting plate 641. The arrangement direction of the second mounting plate 641 and the lead screw motor assembly is the same as that of the first mounting plate 551. The lead screw motor assembly adopts a conventional structure in the art, comprising a lead screw motor 642, a lead screw, and a lead screw nut 643. The lead screw motor 642 drives the lead screw to rotate, causing the lead screw nut 643 to reciprocate on the lead screw. Correspondingly, the third pushing assembly 63 is fixed on the lead screw nut 643. The third pushing assembly 63 includes a vertically arranged third pushing... The cylinder 631 and the third push plate 632 fixed to the output end of the third push cylinder 631 are arranged downward. When the third push cylinder 631 retracts, the third push plate 632 is located above the mosquito coil ring. When the third push cylinder 631 extends, the third push plate 632 and the mosquito coil ring are at the same horizontal height. It should be noted that the second transverse drive mechanism 64 in this embodiment is not limited to the above structure. Other conventional transverse drive mechanisms in the art can also be used, as long as the above effect can be achieved. For example, a stroke cylinder can be used to control the action of the third push component 63.

[0067] When the first conveyor belt 1 and the second conveyor belt 2 are feeding normally, the return conveyor belt 3 is in return mode and will not roll back and forth. Only when the return pushing mechanism 5 pushes the mosquito coil rings to the inlet end of the return conveyor belt 3 will the return conveyor belt 3 move a short distance towards the outlet end, thus leaving space for the next mosquito coil ring to enter. Since the fourth sensor 61 is located near the outlet end of the return conveyor belt 3, when the fourth sensor 61 detects mosquito coil rings, it means that the return conveyor belt 3 is almost full of mosquito coil rings. At this time, the fourth sensor 61 sends a signal to the main control terminal, and the main control terminal controls the return conveyor belt 3 to roll normally, driving the mosquito coil rings towards the return conveyor belt 3. As the mosquito coil moves towards the outlet end of the return conveyor belt 3, it is blocked by the diversion baffle 30. When the fifth sensor 62 at the outlet end of the return conveyor belt 3 senses the mosquito coil, the lead screw motor 642 drives the lead screw nut 643 to move back and forth, and the third push cylinder 631 extends, so that the third push plate 632 continuously pushes the mosquito coil at the outlet end of the return conveyor belt 3 to the first conveyor belt 1 or the second conveyor belt 2 to achieve the diversion effect. When the fifth sensor 62 does not detect the mosquito coil, it means that the mosquito coil on the return conveyor belt 3 has been diverted, and the return conveyor belt 3 returns to the return mode until the fourth sensor 61 detects the mosquito coil again and repeats the above action.

[0068] Preferably, to prevent the diversion and pushing mechanism 6 from pushing the mosquito coil rings on the return conveyor belt 3 into contact with the normally conveyed mosquito coil rings on the first conveyor belt 1 or the second conveyor belt 2 during operation, the frame 100 is also provided with a sensing mechanism 7 for sensing whether there are mosquito coil rings on the first conveyor belt 1 or the second conveyor belt 2. The sensing mechanism 7 is located at the inlet end of the first conveyor belt 1 and the second conveyor belt 2 near the outlet end of the return conveyor belt 3. Preferably, the sensing mechanism 7 in this embodiment is a grating sensor; the grating sensor is fixed on both sides of the first conveyor belt 1 and the second conveyor belt 2 respectively. When the diversion and pushing mechanism 6 is working, the grating sensor is activated. When a mosquito coil enters from the inlet end of the first conveyor belt 1 or the second conveyor belt 2 and is conveyed to the vicinity of the diversion and pushing mechanism 6, it will first be detected by the grating sensor. The grating sensor sends a signal to the main control terminal, which controls the third cylinder to retract, preventing the third push plate 632 from pushing the mosquito coil on the outlet end of the return conveyor belt 3 to touch the mosquito coil normally conveyed on the first conveyor belt 1 or the second conveyor belt 2, thus avoiding damage to the mosquito coil. It should be noted that the sensing mechanism 7 in this embodiment is not limited to using a grating sensor, but can also use other conventional photoelectric sensing mechanisms in the art, as long as they can achieve the above-mentioned effect.

[0069] like Figure 1 and Figure 4As shown, the feeding mechanism 4 includes a first feeding sensor 41 and a second feeding sensor 42 spaced apart on the frame 100, and a feeding push assembly 43 for pushing the mosquito coil rings on the first conveyor belt 1 or the second conveyor belt 2 to the corresponding discharge port 10. The first feeding sensor 41, the second feeding sensor 42, and the feeding push assembly 43 are all arranged sequentially along the conveying direction of the corresponding first conveyor belt 1 or the second conveyor belt 2. The first feeding sensor 41 and the second feeding sensor 42 are both located above the first conveyor belt 1 or the second conveyor belt 2. The frame 100 is provided with a support plate 44 for carrying the mosquito coil rings at the discharge port 10. The outlet of the support plate 44 is provided with a discharge baffle 45 and a control mechanism (not shown in the figure) for controlling the opening of the discharge baffle 45. The control mechanism is connected to the main control terminal. The control mechanism controls the opening of the discharge baffle 45 to feed materials to the corresponding material handling or packaging mechanism. The control mechanism adopts a conventional cylinder or motor in the art, as long as it can open or close the discharge baffle 45. This embodiment does not limit it here. A discharge sensor 46 is provided above the discharge baffle 45. The feeding and pushing assembly 43 includes a horizontally arranged feeding cylinder 431 and a feeding push plate 432 fixed to the output end of the feeding cylinder 431, as well as a fixing plate 433 fixed to the frame 100 for mounting the feeding cylinder 431. The output end of the feeding cylinder 431 faces the discharge port 10. Specifically, a connecting plate 434 is fixed to the output end of the feeding cylinder 431. A connecting rod 435 is fixed on the connecting plate 434. The connecting rod 435 is arranged vertically. The feeding push plate 432 is fixed to the lower end of the connecting rod 435.

[0070] When the discharge sensor 46 above the discharge baffle 45 does not detect the mosquito coil ring, it indicates a material shortage. The discharge sensor 46 sends a signal to the main control terminal, which will prioritize controlling the corresponding feeding mechanism 4. Taking the first conveyor belt 1 as an example, when the mosquito coil ring on the first conveyor belt 1 passes the feeding mechanism 4, it will first pass the first feeding sensor 41, the second feeding sensor 42, and the feeding push component 43 in sequence. Only after the first feeding sensor 41 detects the mosquito coil ring and the second feeding sensor 42 detects it will the main control terminal control the feeding cylinder 431 to operate, thus discharging the mosquito coil ring. The pusher plate 432 pushes the mosquito coil ring from the discharge port 10 to the support plate 44. When the mosquito coil ring is pushed to the support plate 44, it is blocked by the discharge baffle 45. It should be noted that the function of the first feeding sensor 41 is pre-detection. Only when the first feeding sensor 41 and the second feeding sensor 42 detect the mosquito coil ring in sequence will the main control terminal control the feeding cylinder 431 to act. This can effectively prevent the mosquito coil ring from being pushed out of place or even tilted by the feeding pusher plate 432 due to the excessive conveying speed of the first conveyor belt 1 or the untimely feedback of a single feeding sensor.

[0071] Preferably, the feeding mechanism 4 also includes a blockage sensor 47 disposed above the support plate 44. The blockage sensor 47 is located on the support plate 44 near the discharge port 10. Under normal circumstances, in order to prevent frequent material shortages, the main control terminal will control the feeding mechanism 4 to automatically push material to the discharge port 10 at regular intervals. When the material handling mechanism or packaging mechanism corresponding to a certain discharge port 10 malfunctions and operates slowly, causing too many mosquito coils to accumulate on the support plate 44, the mosquito coils will continue to accumulate and remain below the blockage sensor 47 for a long time. When the blockage sensor 47 continuously detects mosquito coils below, it indicates a blockage, meaning that the mosquito coils have accumulated to fill the entire support plate 44. At this time, the feeding mechanism 4 at that location will stop pushing material, and the main control terminal will issue an alarm to the feeding mechanism 4 at that location (correspondingly, an alarm needs to be installed at each discharge port 10) to remind the staff to clean up the mosquito coils in time to avoid the mosquito coils blocking the first conveyor belt 1 or the second conveyor belt 2, affecting the normal operation of the entire return system.

[0072] The working process of the sorting and return system of this utility model is as follows:

[0073] The mosquito coil rings are conveyed from the inlet end of the first conveyor belt 1 and the outlet end of the second conveyor belt 2 respectively. When the mosquito coil rings pass through each feeding mechanism 4, the feeding mechanism 4 pushes the mosquito coil rings on the first conveyor belt 1 or the second conveyor belt 2 to the corresponding discharge port 10, thereby continuously providing mosquito coil rings to the material handling mechanism or packaging mechanism corresponding to each discharge port 10. The excess mosquito coil rings that are not pushed by the feeding mechanism 4 are blocked by the first return baffle 201 and the second return baffle 202 respectively when they are conveyed to the outlet end of the first conveyor belt 1 and the outlet end of the second conveyor belt 2, and are pushed in an orderly manner by the return pushing mechanism 5 to the middle return conveyor belt 3.

[0074] After the mosquito coil rings on the first conveyor belt 1 or the second conveyor belt 2 are pushed to the return conveyor belt 3, the main control terminal will control the return conveyor belt 3 to move a certain distance towards the outlet end, so that the next mosquito coil ring can be sent into the return conveyor belt 3. At this time, the return conveyor belt 3 is in return mode. When the fourth sensor 61 detects the mosquito coil ring, it means that the return conveyor belt 3 is almost full of mosquito coil rings. At this time, the fourth sensor 61 sends a signal to the main control terminal, and the main control terminal controls the return conveyor belt 3 to roll normally, driving the mosquito coil rings to move towards the outlet end of the return conveyor belt 3. When the fifth sensor 62 located at the outlet end of the return conveyor belt 3 senses the mosquito coil ring, the main control terminal controls the diversion and pushing mechanism 6 to continuously push the mosquito coil rings located at the outlet end of the return conveyor belt 3 onto the first conveyor belt 1 or the second conveyor belt 2.

[0075] When the diversion and pushing mechanism 6 is working, the sensing mechanism 7 (grating sensor) is activated. When a mosquito coil ring enters from the inlet end of the first conveyor belt 1 or the second conveyor belt 2 and is transported to a location near the diversion and pushing mechanism 6, it will be detected by the grating sensor first. The grating sensor sends a signal to the main control terminal, which controls the third pushing cylinder 631 to retract, preventing the third push plate 632 from pushing the mosquito coil ring on the outlet end of the return conveyor belt 3 to touch the mosquito coil ring normally transported on the first conveyor belt 1 or the second conveyor belt 2, thus avoiding damage caused by collision. When the fifth sensor 62 does not detect a mosquito coil ring, it means that the mosquito coil ring on the return conveyor belt 3 has been diverted, and the return conveyor belt 3 returns to the return mode. The above actions are repeated until the fourth sensor 61 detects a mosquito coil ring again, thus achieving a cyclical return conveying effect.

[0076] This utility model's mosquito coil ring sorting and return system, by setting a first conveyor belt 1, a second conveyor belt 2, and a third conveyor belt 3 on a frame, and by setting multiple feeding mechanisms 4 to push the mosquito coil rings on the first conveyor belt 1 or the second conveyor belt 2 to the corresponding discharge port 10, continuously provides mosquito coil rings to the material handling mechanism or packaging mechanism corresponding to each discharge port 10. Furthermore, a return pushing mechanism 5 is set on the frame 100 to push the mosquito coil rings on the first conveyor belt 1 or the second conveyor belt 2 to the return conveyor belt 3, and a diversion pushing mechanism 6 is set to push the mosquito coil rings on the return conveyor belt 3 to the first conveyor belt 1 or the second conveyor belt 2, achieving a cyclical return conveying effect. It has a high degree of automation and can be adapted to mosquito coil machine production lines composed of multiple material handling mechanisms or multiple packaging machines, meeting the high-efficiency production needs of enterprises.
