Description

Technical Field

[0001] This utility model relates to the field of waste collection technology, and in particular to a negative pressure collection device for minute waste. Background Technology

[0002] In industrial production, various types of micro-waste are inevitably generated. To maintain a stable and orderly production environment, it is necessary to collect this micro-waste. Related technologies primarily employ two methods for collecting micro-waste. The first method uses pre-designated troughs in the equipment to collect fallen micro-waste. However, due to equipment vibration and the blowing action during cleaning, micro-waste flies everywhere, affecting the aesthetics and cleanliness of the area around the equipment, requiring frequent shutdowns for cleaning. The second method involves using a vacuum cleaner throughout the entire process. However, vacuum cleaners are expensive, and their operation generates significant noise, severely impacting the user experience and causing noise pollution. Furthermore, due to structural defects, prolonged continuous operation of the vacuum cleaner can easily lead to its burnout. It is evident that the existing methods for collecting micro-waste in these technologies do not meet customer needs. Utility Model Content

[0003] Therefore, it is necessary to provide a negative pressure collection device for micro-waste, addressing the problem that the existing methods for collecting micro-waste in related technologies cannot meet the needs of customers.

[0004] A negative pressure collection device for minute waste materials includes a controller, a translation cylinder, a vacuum generator, a suction nozzle, and a material tube;

[0005] The vacuum generator is connected to the suction nozzle and the material tube respectively, the output shaft of the translation cylinder is connected to the vacuum generator, and the controller is electrically connected to the vacuum generator and the translation cylinder respectively.

[0006] The controller is used to control the translation cylinder to move the vacuum generator from the waiting station to the material suction station, and to control the vacuum generator to perform material suction at the material suction station.

[0007] When the aforementioned negative pressure collection device for minute waste materials is in operation, the controller first controls the translation cylinder to move the vacuum generator from the waiting station to the suction station. Then, the controller controls the vacuum generator to suction materials at the suction station. After a preset suction time, the controller controls the translation cylinder to move the vacuum generator from the suction station back to the waiting station, and simultaneously stops suctioning materials. During suction, the vacuum generator generates negative pressure, causing the minute waste materials to enter the vacuum generator through the suction nozzle and then through the material pipe. The material pipe collects the minute waste materials, thus maintaining a stable and orderly production environment. Compared with existing technologies, this negative pressure collection device for minute waste materials does not cause minute waste materials to fly everywhere, does not generate noise, and effectively saves energy.

[0008] In one embodiment, the controller includes a control circuit and a power supply, the power supply being used to power the control circuit.

[0009] In one embodiment, the control circuit includes an intermediate relay, a first magnetic switch, a second magnetic switch, a first solenoid valve, a second solenoid valve, a first time relay, and a second time relay;

[0010] The intermediate relay includes a first contact switch, a second contact switch, and a first coil; the first time relay includes a second coil and a third contact switch; and the second time relay includes a third coil and a fourth contact switch.

[0011] The positive terminal of the power supply is connected to one end of the first contact switch, one end of the first magnetic switch, and one end of the second contact switch. The other end of the first contact switch is connected to one end of the first coil, one end of the first solenoid valve, and the other end of the first magnetic switch. The other end of the first magnetic switch is connected to one end of the first coil and one end of the first solenoid valve. The other end of the second contact switch is connected to one end of the second solenoid valve and one end of the second magnetic switch. The other end of the second magnetic switch is connected to one end of the second coil and one end of the third coil. The other end of the second coil is connected to one end of the third contact switch, one end of the fourth contact switch, and the negative terminal of the power supply. The other end of the third coil is connected to the other end of the third contact switch, the other end of the fourth contact switch, the other end of the first coil, the other end of the first solenoid valve, and the other end of the second solenoid valve.

[0012] The first magnetic switch is triggered by an external cylinder, the first solenoid valve is used to control the reciprocating motion of the translation cylinder, the second solenoid valve is used to control the opening and closing of the vacuum generator, the second magnetic switch is triggered by the translation cylinder, the third contact switch is a normally open contact switch with a time delay, and the fourth contact switch is a normally closed contact switch.

[0013] When the control circuit is working, the first magnetic switch is first triggered by an external cylinder to close. At this time, the control circuit forms a conductive loop consisting of the positive terminal of the power supply, the first magnetic switch, the first solenoid valve, the fourth contact switch, and the negative terminal of the power supply. The first coil is energized in parallel across the first solenoid valve, causing the first and second contact switches to close. After the first and second contact switches close, the intermediate relay forms a self-locking loop. Even if the first magnetic switch is opened, the control circuit still has conductive loops consisting of the positive terminal of the power supply, the first contact switch, the first solenoid valve, the fourth contact switch, and the negative terminal of the power supply, as well as conductive loops consisting of the positive terminal of the power supply, the second contact switch, the second solenoid valve, the fourth contact switch, and the negative terminal of the power supply. Both the first and second solenoid valves are energized. After the first solenoid valve is energized, it controls the translation cylinder to move from the waiting position to the suction position. After the second solenoid valve is energized, it controls the vacuum generator to start and generate negative pressure. When the translation cylinder reaches the suction station, the second magnetic switch senses this and closes. The first and second time relays are simultaneously energized. At this time, the fourth contact switch opens, and the third contact switch closes. The third contact switch opens after a preset time. Since the fourth contact switch has also opened, the first and second solenoid valves and the intermediate relay are all energized. After the first solenoid valve is energized, it controls the translation cylinder to move from the suction station to the waiting station, causing the second magnetic switch to open. After the second solenoid valve is energized, it controls the vacuum generator to shut down and cease generating negative pressure. After the intermediate relay is energized, both the first and second contact switches open. At this point, the control circuit returns to the state before the external cylinder triggered the first magnetic switch to close. When the external cylinder triggers the first magnetic switch to close again, the control circuit continues to perform automated control in the same manner. It can be seen that this control circuit has a high degree of automation and can effectively improve the working efficiency of the aforementioned negative pressure collection device for small waste materials.

[0014] In one embodiment, the output voltage of the power supply is 24V.

[0015] In one embodiment, the negative pressure collection device for the micro-waste further includes an elbow, through which the vacuum generator is connected to the material pipe.

[0016] In one embodiment, a collection box is connected to the end of the feed tube.

[0017] In one embodiment, the translation cylinder is mounted on a fixed plate.

[0018] In one embodiment, the second magnetic switch is installed at the material suction station. Attached Figure Description

[0025] This utility model discloses a negative pressure collection device for tiny waste materials.

[0026] like Figure 1 As shown, the negative pressure collection device for small waste materials includes a controller, a translation cylinder 10, a vacuum generator 20, a suction nozzle 30, and a material pipe 40. The vacuum generator 20 is connected to both the suction nozzle 30 and the material pipe 40. The output shaft of the translation cylinder 10 is connected to the vacuum generator 20. The controller is electrically connected to both the vacuum generator 20 and the translation cylinder 10. The controller is used to control the translation cylinder 10 to move the vacuum generator 20 from the waiting position to the suction position, and to control the vacuum generator 20 to perform suction at the suction position.

[0027] When the aforementioned negative pressure collection device for minute waste materials is in operation, the controller first controls the translation cylinder to move the vacuum generator from the waiting station to the suction station. Then, the controller controls the vacuum generator to suction materials at the suction station. After a preset suction time, the controller controls the translation cylinder to move the vacuum generator from the suction station back to the waiting station, and simultaneously stops suctioning materials. During suction, the vacuum generator generates negative pressure, causing the minute waste materials to enter the vacuum generator through the suction nozzle and then through the material pipe. The material pipe collects the minute waste materials, thus maintaining a stable and orderly production environment. Compared with existing technologies, this negative pressure collection device for minute waste materials does not cause minute waste materials to fly everywhere, does not generate noise, and effectively saves energy.

[0028] The controller includes a control circuit and a power supply, which supplies power to the control circuit.

[0029] like Figure 2As shown, the control circuit includes an intermediate relay, a first magnetic switch S1, a second magnetic switch S2, a first solenoid valve YV1, a second solenoid valve YV2, a first time relay, and a second time relay. The intermediate relay includes a first contact switch KA2, a second contact switch KA3, and a first coil KA1. The first time relay includes a second coil KT1 and a third contact switch KT2. The second time relay includes a third coil KT3 and a fourth contact switch KT4. The positive terminal L of the power supply is connected to one end of the first contact switch KA2, one end of the first magnetic switch S1, and one end of the second contact switch KA3. The other end of the first contact switch KA2 is connected to one end of the first coil KA1, one end of the first solenoid valve YV1, and the other end of the first magnetic switch S1. The other end of the first magnetic switch S1 is connected to one end of the first coil KA1 and one end of the first solenoid valve YV1. The other end of the second contact switch KA3 is connected to... One end of the second solenoid valve YV2 and one end of the second magnetic switch S2 are connected. The other end of the second magnetic switch S2 is connected to one end of the second coil KT1 and one end of the third coil KT3. The other end of the second coil KT1 is connected to one end of the third contact switch KT2, one end of the fourth contact switch KT4, and the negative terminal N of the power supply. The other end of the third coil KT3 is connected to the other end of the third contact switch KT2, the other end of the fourth contact switch KT4, the other end of the first coil KA1, the other end of the first solenoid valve YV1, and the other end of the second solenoid valve YV2. The first magnetic switch S1 is triggered by an external cylinder. The first solenoid valve YV1 is used to control the reciprocating motion of the translation cylinder 10. The second solenoid valve YV2 is used to control the opening and closing of the vacuum generator 20. The second magnetic switch S2 is triggered by the translation cylinder 10. The third contact switch KT2 is a normally open contact switch with a time delay. The fourth contact switch KT4 is a normally closed contact switch.

[0030] When the control circuit is working, the first magnetic switch is first triggered by an external cylinder to close. At this time, the control circuit forms a conductive loop consisting of the positive terminal of the power supply, the first magnetic switch, the first solenoid valve, the fourth contact switch, and the negative terminal of the power supply. The first coil is energized in parallel across the first solenoid valve, causing the first and second contact switches to close. After the first and second contact switches close, the intermediate relay forms a self-locking loop. Even if the first magnetic switch is opened, the control circuit still has conductive loops consisting of the positive terminal of the power supply, the first contact switch, the first solenoid valve, the fourth contact switch, and the negative terminal of the power supply, as well as conductive loops consisting of the positive terminal of the power supply, the second contact switch, the second solenoid valve, the fourth contact switch, and the negative terminal of the power supply. Both the first and second solenoid valves are energized. After the first solenoid valve is energized, it controls the translation cylinder to move from the waiting position to the suction position. After the second solenoid valve is energized, it controls the vacuum generator to start and generate negative pressure. When the translation cylinder reaches the suction station, the second magnetic switch senses this and closes. The first and second time relays are simultaneously energized. At this time, the fourth contact switch opens, and the third contact switch closes. The third contact switch opens after a preset time. Since the fourth contact switch has also opened, the first and second solenoid valves and the intermediate relay are all energized. After the first solenoid valve is energized, it controls the translation cylinder to move from the suction station to the waiting station, causing the second magnetic switch to open. After the second solenoid valve is energized, it controls the vacuum generator to shut down and cease generating negative pressure. After the intermediate relay is energized, both the first and second contact switches open. At this point, the control circuit returns to the state before the external cylinder triggered the first magnetic switch to close. When the external cylinder triggers the first magnetic switch to close again, the control circuit continues to perform automated control in the same manner. It can be seen that this control circuit has a high degree of automation and can effectively improve the working efficiency of the aforementioned negative pressure collection device for small waste materials.

[0031] The output voltage of the power supply can be set according to actual needs. Preferably, the output voltage of the power supply is 24V.

[0032] The negative pressure collection device for the micro-waste includes an elbow 50, through which the vacuum generator 20 is connected to the material pipe 40. The elbow 50 facilitates the installation of the material pipe 40. Furthermore, a collection box is connected to the end of the material pipe 40. The collection box allows for more efficient collection of micro-waste.

[0033] The translation cylinder 10 is mounted on the fixed plate 60. The fixed plate 60 ensures a more stable installation of the translation cylinder 10. Furthermore, the second magnetic switch S2 is installed at the material suction station. This installation allows the second magnetic switch S2 to better sense the position of the translation cylinder, thereby improving the control effect of the control circuit.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
