Description

Technical Field

[0001] The invention relates to the technical field of mosquito coil production, in particular to an automatic powder stirring device. Background Art

[0002] The automatic powder stirring device for mosquito coil production is usually composed of a stirring box, a motor, a transmission device, a stirring rod, etc. The device is driven by the motor to make the stirring rod mix the powder in the stirring box, thereby achieving the purpose of uniform mixing.

[0003] After searching, a Chinese patent with announcement number CN220534600U discloses a coating production device, including a frame, a mixing tank is fixedly connected to the frame, a stirring structure is arranged inside the mixing tank, a motor for driving the stirring structure is also installed on the frame, an exhaust assembly is arranged on the frame, and a dust suction assembly used in conjunction with the exhaust assembly is also arranged on the frame. When the aerogel production device proposed in the above scheme is in use, when the staff is pouring the powder raw material, the annular dust suction pipe can extract the dust flying in the environment, and the air bag discharges the dust into the dust collecting box, which can collect the dust, not only can the dust be prevented from polluting the environment around the equipment, but also can be prevented from being inhaled into the body by the staff operating the equipment, providing protection for the health of the workers, and improving the practicality of the aerogel production device. However, the above scheme still has the following shortcomings when it is actually used: During the mixing process of mosquito coil powder, due to the physical properties of the powder and the operation mode of the mixing equipment, a certain amount of dust will be generated. First, the powder itself may have a high specific surface area and a low bulk density, which leads to large gaps between the powder particles and easy formation of dust. Secondly, when the mixing rod, mixing blades and other components of the mixing equipment are running at high speed, they will produce strong shearing, extrusion and friction effects on the powder. These mechanical forces will cause the powder particles to break and refine and generate a large amount of dust. However, the mixing equipment proposed in the above scheme does not have the function of absorbing dust. If the mixing device is not equipped with an effective dust absorption or treatment system, the dust will escape into the air, which will not only pollute the production environment, but also pose a threat to the health of the operators. Long-term inhalation of dust may cause workers to suffer from respiratory diseases, pneumoconiosis and other occupational diseases, seriously affecting their health.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-11 , an automatic powder stirring device, including a frame 1, a mixing tank 2, a dust suction structure, a dust blowing structure, a rotating structure, two air suction parts, two air supply parts and a dust collection structure, the mixing tank 2 is installed on the frame 1, and a motor 3 and a reducer 4 are arranged on the frame 1, and the output shaft of the motor 3 and the input shaft of the reducer 4 are connected by a transmission member, and a rotatable stirring shaft 5 is arranged inside the mixing tank 2, and stirring blades are installed on the stirring shaft 5, and the stirring shaft 5 is fixedly connected to the output shaft of the reducer 4. The staff puts the mosquito-repellent powder into the mixing tank 2, and then starts the motor 3. When the motor 3 is running, the reducer 4 is driven to rotate through the transmission member, and the reducer 4 drives the stirring shaft 5 to rotate. During the rotation of the stirring shaft 5, a plurality of stirring blades thereon jointly complete the stirring effect on the powder; The dust suction structure is arranged on the mixing tank 2, and is used for absorbing the dust generated during the powder mixing process. The dust suction structure includes an air suction pipe 61, a main pipe 63 and a rotary joint 64. The air suction pipe 61 is fixed at the top of the stirring shaft 5, and the air suction pipe 61 and the stirring shaft 5 are coaxially arranged. A plurality of air suction holes 62 are opened on the air suction pipe 61, and the main pipe 63 is fixed just above the mixing tank 2.

The fixed part of the rotary joint 64 is connected to the inside of the air suction pipe 61, and the rotating part of the rotary joint 64 is connected to a connecting pipe 65. The end of the connecting pipe 65 away from the rotary joint 64 is connected to the main pipe 63. The setting of the rotary joint 64 enables the connecting pipe 65 and the air suction pipe 61 to rotate relative to each other, so as to prevent the connecting pipe 65 from being entangled on the air suction pipe 61 when the air suction pipe 61 rotates with the stirring shaft 5. The dust blowing structure is arranged on the inner wall of the mixing tank 2, and is used to blow the dust toward the dust suction structure. The dust blowing structure includes a plurality of air outlet pipes 71 and a plurality of connecting pipes 73. The plurality of air outlet pipes 71 are fixed on the inner wall of the mixing tank 2, and the plurality of air outlet pipes 71 are distributed in a circumferential array around the stirring shaft 5. A plurality of air outlet holes 72 are provided on each air outlet pipe 71, and two adjacent air outlet pipes 71 are connected through a connecting pipe 73. Each air outlet hole 72 is arranged toward the air suction pipe 61, and the gas will be ejected through the plurality of air outlet holes 72. Since each air outlet hole 72 is arranged toward the air suction pipe 61, the gas ejected from the plurality of air outlet holes 72 can blow the dust toward the direction of the air suction pipe 61, which is conducive to the dust being absorbed by the plurality of air suction holes 62. The rotating structure is arranged on the frame 1, and the rotating structure is driven by the input shaft of the reducer 4. The rotating structure includes a fixed plate 81, and the rotating structure also includes two brackets 82, a rotating shaft 83 and an eccentric wheel 84. One end of each of the two brackets 82 is fixed on the frame 1, and the other end of each of the two brackets 82 is fixedly connected to the fixed plate 81. The rotating shaft 83 is rotatably mounted in the middle position of the side of the fixed plate 81. The eccentric wheel 84 is fixedly sleeved on the rotating shaft 83. The eccentric wheel 84 and the rotating shaft 83 are eccentrically arranged, and the rotating shaft 83 is away from the fixed plate 81. One end of the fixed plate 81 is connected to the input shaft of the reducer 4. When the input shaft of the reducer 4 rotates, it can also drive the rotating shaft 83 to rotate, and the eccentric wheel 84 on the rotating shaft 83 will also rotate accordingly. When the eccentric wheel 84 rotates, it will squeeze the four fixed rods 94 in sequence. When the eccentric wheel 84 squeezes the fixed rod 94, the fixed rod 94 will move and drive the corresponding sliding plug 92 to move. Therefore, when the eccentric wheel 84 rotates, it can drive the two suction parts and the two air supply parts to operate in sequence. The two air suction members and the two air supply members are arranged on the fixed plate 81, the two air suction members are arranged opposite to each other, the two air supply members are arranged opposite to each other, the two air suction members and the two air supply members are distributed in a circumferential array around the center of the fixed plate 81, the air suction members and the air supply members have the same structure, both include a sealing cylinder 91, a sliding plug 92, a fixing rod 94 and two mounting tubes 95, the sealing cylinder 91 is fixed to the side of the fixed plate 81, the sliding plug 92 is sealingly and slidingly connected to the inside of the sealing cylinder 91, one end of the fixing rod 94 is fixed to the sliding plug 92, and the other end of the fixing rod 94 extends to the outside of the sealing cylinder 91, the fixing rod 94 passes through the sealing cylinder 91, and the fixing rod 94 and the sealing cylinder 91 are slidingly connected, the sealing cylinder 91 and the sliding plug 92 are connected by a spring 93, and the two mounting tubes 95 are connected to the sealing cylinder 91. One-way valves 96 are installed on the two mounting tubes 95. The two one-way valves 96 on the same sealing cylinder 91 have opposite flow limiting directions. One of the one-way valves 96 limits the gas to only enter the sealing cylinder 91, and the other one-way valve 96 limits the gas to only flow out of the sealing cylinder 91. Therefore, when the sliding plug 92 moves toward one end of the sealing cylinder 91, the sliding plug 92 can press the gas in the sealing cylinder 91 out, and the sealing cylinder 91 performs an exhaust action at this time. When the sliding plug 92 moves toward the other end of the sealing cylinder 91, the sliding plug 92 can draw air into the sealing cylinder 91, and the sealing cylinder 91 performs an exhaust action at this time. Based on the above process, during the reciprocating movement of the sliding plug 92 in the sealing cylinder 91, the air suction part can periodically perform an air suction action, and the air supply part periodically performs an exhaust action. The dust collection structure is arranged on the frame 1 for collecting dust. The dust collection structure comprises a filter cartridge 101, a filter element 102 and a bottom cover 103. The filter cartridge 101 is installed on the frame 1. An air inlet passage is provided on the top of the filter cartridge 101. The bottom of the filter cartridge 101 is open.

The cleaning ring 111 is sleeved on the filter element 102, and the bristles 112 are arranged on the inner ring of the cleaning ring 111, and the bristles 112 are in contact with the outer surface of the filter element 102. The driving member and the vibrating member are both provided on the filter cartridge 101. The driving member is used to drive the cleaning ring 111 to move up and down, and the vibrating member is used to drive the filter element 102 to vibrate. The driving member includes two fixing blocks 113, a screw rod 114, a guide rod 115, a shaft rod 121 and two bevel gears. Wheel 122, two fixed blocks 113 are fixed on the outer surface of the cleaning ring 111, the screw rod 114 is rotatably installed in the filter cartridge 101, and the guide rod 115 is fixed in the filter cartridge 101. One of the fixed blocks 113 is threadedly sleeved on the screw rod 114, and the other fixed block 113 is slidably sleeved on the guide rod 115. The shaft 121 is rotatably installed in the filter cartridge 101 through the bearing seat, and the shaft 121 and the screw rod 114 are fixedly connected. One of the bevel gears 122 is fixedly sleeved on the shaft 121, and the other bevel gear 122 is rotatably sleeved on the shaft 121. The rod 123 is rotatably mounted inside the filter cartridge 101, and the two bevel gears 122 mesh with each other. One end of the rotating rod 123 extends to the outside of the filter cartridge 101 and is provided with a knob. When the rotating rod 123 rotates, the two meshing bevel gears 122 can drive the shaft 121 to rotate, so that the shaft 121 drives the screw rod 114 to rotate. Under the limiting action of the guide rod 115, the screw rod 114 can drive the corresponding fixed block 113 to move when it rotates, thereby causing the cleaning ring 111 to move. During the movement of the cleaning ring 111, the cleaning ring 111 is arranged on the cleaning ring 114. The bristles 112 on the inner ring 11 can brush off the dust attached to the surface of the filter element 102. The vibrating member includes an eccentric disk 116 and a fixed column 117.

The fixed column 117 is fixed to the top of the filter element 102, and the fixed column 117 is arranged opposite to the eccentric disk 116. The eccentric disk 116 will continuously squeeze the fixed column 117 during the rotation process, so that the filter element 102 produces a vibration effect. When the filter element 102 vibrates, the dust attached to the surface of the filter element 102 will be shaken off.

[0021] The specific working principle of the present invention is as follows: When the automatic powder stirring device proposed by the present invention is used, the staff puts the mosquito coil powder into the mixing tank 2, and then starts the motor 3. When the motor 3 is running, it drives the reducer 4 to rotate through the transmission member, and the reducer 4 drives the stirring shaft 5 to rotate. During the rotation of the stirring shaft 5, the several stirring blades on it jointly complete the stirring effect of the powder; When the input shaft of the reducer 4 rotates, it can also drive the rotating shaft 83 to rotate, and the eccentric wheel 84 on the rotating shaft 83 will also rotate accordingly. Figure 5As shown, the eccentric wheel 84 squeezes the four fixed rods 94 in sequence during the rotation process. When the eccentric wheel 84 squeezes the fixed rods 94, the fixed rods 94 move and drive the corresponding sliding plugs 92 to move. Therefore, the eccentric wheel 84 can drive the two suction parts and the two air supply parts to operate in sequence during the rotation process. For the two suction parts and the two air supply parts, the two suction parts are arranged opposite to each other, and the two air supply parts are also arranged opposite to each other, and the two suction parts and the two air supply parts are distributed in a circumferential array around the rotating shaft 83. The two suction parts are used to absorb the gas in the suction pipe 61 so that the suction parts can perform dust collection, and the two air supply parts are used to absorb the gas in the suction pipe 61 so that the suction parts can perform dust collection, and the two air supply parts can perform dust collection. It is used to supply gas into the plurality of gas outlet pipes 71 so that the gas is ejected through the plurality of gas outlet holes 72. Based on the above process, when the device stirs the powder, the plurality of gas intake holes 62 on the gas intake pipe 61 can absorb the dust generated during the stirring process. At the same time, the gas will be ejected through the plurality of gas outlet holes 72. Since each gas outlet hole 72 is arranged toward the gas intake pipe 61, the gas ejected from the plurality of gas outlet holes 72 can blow the dust toward the direction of the gas intake pipe 61, which is conducive to the dust being absorbed by the plurality of gas intake holes 62. This design can collect the dust generated during the stirring process and prevent the dust from flying around. It is worth noting that the number of the air suction parts and the air supply parts is set to two, which enables the two air suction parts and the two air supply parts to operate alternately, thereby allowing the air suction action and the air supply action to be carried out continuously, avoiding the window period between the air suction action and the air supply action, thereby ensuring the dust absorption effect of the device; The air suction member and the air supply member are the key points in the present invention. The structures of the air suction member and the air supply member are exactly the same. Specifically, the flow limiting directions of the two one-way valves 96 on the sealing cylinder 91 are opposite. Specifically, one of the one-way valves 96 limits the gas to only enter the sealing cylinder 91, and the other one-way valve 96 limits the gas to only flow out of the sealing cylinder 91. Therefore, when the sliding plug 92 moves toward one end of the sealing cylinder 91, the sliding plug 92 can press the gas in the sealing cylinder 91 out, and the sealing cylinder 91 performs an exhaust action. When the sliding plug 92 moves toward the other end of the sealing cylinder 91, the sliding plug 92 can press the gas in the sealing cylinder 91 out. Air is drawn into the sealing cylinder 91, and the sealing cylinder 91 performs an air extraction action. Based on the above process, during the reciprocating movement of the sliding plug 92 in the sealing cylinder 91, the suction member can periodically perform an air suction action, and the air supply member can periodically perform an air exhaust action. In terms of pipeline setting, for the two suction members, one of the mounting tubes 95 on the sealing cylinder 91 is connected to the main pipe 63, and the other mounting tube 95 is connected to the filter cylinder 101. For the two air supply members, one of the mounting tubes 95 on the sealing cylinder 91 is connected to the external environment, and the other mounting tube 95 is connected to one of the air outlet pipes 71. Under the suction action of the two suction parts, the absorbed dust will be discharged into the filter cartridge 101 through the corresponding installation pipe 95. A filter element 102 is arranged inside the filter cartridge 101. The dust will adhere to the filter element 102, and the gas will be discharged through the exhaust pipe 104. This design collects the absorbed dust and is convenient for the staff to uniformly handle the dust. Furthermore, when it is necessary to collect the dust attached to the surface of the filter element 102, the staff can turn the knob to make the knob drive the rotating rod 123 to rotate. When the rotating rod 123 rotates, it can drive the shaft 121 to rotate through two mutually meshing bevel gears 122, so that the shaft 121 drives the screw rod 114 to rotate. Under the limiting action of the guide rod 115, the screw rod 114 can drive the corresponding fixed block 113 to move when it rotates, which makes the cleaning ring 111 move. During the movement of the cleaning ring 111 In the embodiment, the bristles 112 arranged on the inner ring of the cleaning ring 111 can brush off the dust attached to the surface of the filter element 102. In addition, when the shaft 121 rotates, the eccentric disk 116 thereon will rotate accordingly. During the rotation, the eccentric disk 116 will continuously squeeze the fixing column 117, so that the filter element 102 produces a vibration effect. When the filter element 102 vibrates, the dust attached to the surface of the filter element 102 will be shaken off. Therefore, under the combination of the brushing effect of the bristles 112 and the vibration effect of the filter element 102, the dust attached to the surface of the filter element 102 will fall smoothly and fall on the bottom cover 103. The staff can quickly deal with the dust by removing the bottom cover 103. It should be noted that the filter element 102 is connected to the two fixing rings 105 through two annular capsules 106. The elastic characteristics of the annular capsules 106 are used to support the filter element 102 to produce a vibration effect. It is worth mentioning that the distinguishing technical features between this application and the comparative document CN220534600U include: The dust blowing structure is arranged on the inner wall of the mixing tank 2, and is used to blow the dust to the dust suction structure. The comparative document CN220534600U does not disclose this technical feature. In the present application, the dust blowing structure is arranged on the inner wall of the mixing tank 2, and is used to blow the dust to the dust suction structure. The dust blowing structure includes a plurality of air outlet pipes 71 and a plurality of connecting pipes 73. The plurality of air outlet pipes 71 are fixed on the inner wall of the mixing tank 2, and the plurality of air outlet pipes 71 are distributed in a circumferential array around the stirring shaft 5, and each air outlet pipe 71 is provided with a plurality of air outlet holes 72. Two adjacent air outlet pipes 71 are connected by a connecting pipe 73, and each air outlet hole 72 is arranged toward the air intake pipe 61. When the device stirs the powder, the plurality of air intake holes 62 on the air intake pipe 61 can absorb the dust generated during the stirring process. At the same time, the gas will be ejected through the plurality of air outlet holes 72. Since each air outlet hole 72 is arranged toward the air intake pipe 61, the gas ejected from the plurality of air outlet holes 72 can blow the dust toward the direction of the air intake pipe 61, which is conducive to the dust being absorbed by the plurality of air intake holes 62. In addition, the distinguishing technical features between this application and the reference document CN220534600U also include: The dust collection structure is arranged on the frame 1 for collecting dust. The interior of the filter cartridge 101 is provided with a dust cleaning structure, which includes a cleaning ring 111, bristles 112, a driving member and a vibrating member. The comparative document CN220534600U does not disclose this technical feature. In the present application, the absorbed dust will be discharged into the filter cartridge 101 through the corresponding mounting pipe 95. The filter cartridge 101 is provided with a filter element 102. The dust will adhere to the filter element 102, and the gas will pass through the exhaust. The air pipe 104 is discharged. This design collects the absorbed dust, which is convenient for the staff to uniformly handle the dust. Furthermore, when it is necessary to collect the dust attached to the surface of the filter element 102, the staff can turn the knob to make the knob drive the rotating rod 123 to rotate. When the rotating rod 123 rotates, it can drive the shaft 121 to rotate through two mutually meshing bevel gears 122, so that the shaft 121 drives the screw rod 114 to rotate. Under the limiting action of the guide rod 115, the screw rod 114 can rotate when it rotates. The corresponding fixing block 113 is driven to move, which makes the cleaning ring 111 move. During the movement of the cleaning ring 111, the bristles 112 arranged on the inner ring of the cleaning ring 111 can brush off the dust attached to the surface of the filter element 102. In addition, when the shaft 121 rotates, the eccentric disk 116 thereon will rotate accordingly. During the rotation process, the eccentric disk 116 will continuously squeeze the fixing column 117, so that the filter element 102 vibrates. When the filter element 102 vibrates, the dust attached to the filter element 102 is The dust on the surface of the core 102 will be shaken off. Therefore, under the combination of the brushing action of the bristles 112 and the vibration action of the filter element 102, the dust attached to the surface of the filter element 102 will fall smoothly and fall on the bottom cover 103. The staff can quickly deal with the dust by removing the bottom cover 103. It should be noted that the filter element 102 is connected to the two fixing rings 105 through two annular capsules 106. The elastic characteristics of the annular capsules 106 are used to support the filter element 102 to produce a vibration effect. Through the above two distinguishing technical features, the benefits that this application can achieve are: 1. During the mixing process of powder, the device effectively absorbs the generated dust through the suction holes on the suction pipe. At the same time, the gas ejected toward the air outlet arranged in the suction pipe can guide the dust to move toward the suction pipe, thereby significantly enhancing the dust absorption efficiency and ensuring the cleanliness and safety of the working environment; 2. An innovative cleaning mechanism has been designed. Through the linkage of components such as knobs, rotating rods, bevel gears, shafts, screws, cleaning rings and bristles, combined with the vibration effect of the filter element, the dust attached to the surface of the filter element can be easily brushed and shaken off. This design not only improves the efficiency and convenience of dust cleaning, but also allows workers to quickly handle dust by simply removing the bottom cover, greatly reducing the workload and ensuring the continued efficient operation of the equipment.
