Description

Technical Field

[0001] The present invention relates to the technical field of anti-rust spraying, and particularly relates to an anti-rust spraying treatment device for fire-fighting equipment. Background Art

[0002] In the field of fire-fighting equipment, the anti-rust treatment of fire extinguisher tanks is of crucial importance. At present, the common anti-rust treatment methods for fire extinguisher tanks mainly include manual spraying and using traditional automated spraying equipment. Manual spraying relies on manual operation by workers, and the anti-rust paint is evenly applied on the surface of the tank through a spray gun; traditional automated spraying equipment imitates the manual spraying action through devices such as robotic arms to achieve the anti-rust treatment of the tank. The drying process usually adopts static air drying or simple drying equipment for treatment.

[0003] However, the existing treatment methods have obvious drawbacks. Manual spraying is not only inefficient and difficult to meet the requirements of large-scale production, but also the spraying effect is greatly affected by the proficiency and working state of workers, and problems such as uneven spraying and dead corners are likely to occur, resulting in poor anti-rust effects. Although traditional automated spraying equipment improves the efficiency to a certain extent, it cannot automatically adjust the spraying angle according to the shape and size of the fire extinguisher tank.

[0034] The working principle of the present invention is as follows: When the device performs rust-proof spraying treatment on the fire extinguisher tank body, it is carried out in sequence according to the order of automatic feeding, fixing the tank body, spraying rust-proof paint, drying treatment, and automatic discharging, realizing the automation and high efficiency of the rust-proof treatment of the fire extinguisher tank body.

[0035] First, the fire extinguisher tank body is transported from the placement frame 421 to the fixing component 41 through the discharging and feeding component 42. The placement frame 421 is used to store the fire extinguisher tank body to be processed. The clamping groove 422 at its discharging end facilitates the automatic gripper 4212 to grab the tank body. The third motor 423 drives the rotating rod 424 and the rotating plate 425 to rotate by a certain degree, so that the automatic gripper 4212 can rotate to facilitate the clamping and placing of the fire extinguisher tank body. The fourth motor 427 drives the threaded rod 428 to rotate, and the threaded block 429 slides up and down in the lifting groove 426, thereby adjusting the height of the automatic gripper 4212. When the automatic gripper 4212 moves to a suitable position, the fifth motor 4210 adjusts the angle of the electric telescopic rod 4211, and the electric telescopic rod 4211 extends, and the automatic gripper 4212 grabs the fire extinguisher tank body, and then transports the tank body to the fixing component 41 (the above are all controlled by the PLC controller, and the main program in the PLC controller is pre-set).

[0036] The fixing component 41 adopts the method of squeezing and fixing from the inside of the fire extinguisher tank body. When the fire extinguisher tank body is placed on the connecting disk 411, the PLC controller controls the first electromagnetic ring 416 to be energized. Since the first electromagnetic ring 416 and the first permanent magnet ring are magnetically repulsive, the first permanent magnet ring drives the sliding piece 415 to slide upward, and further enables the second connecting rod 413 to pull the first connecting rod 412, and the first connecting rod 412 drives the pressing piece 414 to move towards the inside of the tank body, tightly squeezing and fixing the tank body from the inside to ensure that the tank body will not shake during the subsequent processing.

[0037] In the spraying mechanism 5, the material pumping pump 57 conveys the antirust paint to the annular spraying pipe 51 through the annular rotating pipe 56, and then sprays it out from the spraying head 55 on the inner peripheral wall of the annular spraying pipe 51 to spray the fire extinguisher tank body. The sixth motor 71 drives the reciprocating lead screw 72 to rotate. Under the restriction of the reciprocating lead screw 72 and the limiting rod 73, the reciprocating block 74 makes a reciprocating linear motion along the reciprocating lead screw 72. At the same time, since the gear 78 meshes with the first toothed ring 53, the movement of the reciprocating block 74 drives the annular spraying pipe 51 to rotate while moving up and down, so that the spraying head 55 can spray the fire extinguisher tank body in all directions without dead angles.

[0038] During the spraying process, the spraying head 55 is located above, and the detection rod 512 and the detection wheel 514 are located below. The two move downwards from top to bottom together with the annular spraying pipe 51 and the first fixed ring 54. When the tank body enters the arc part from the cylindrical part, the curvature of the tank body surface changes, and the pressure received by the detection wheel 514 when it contacts the tank body surface also changes accordingly. The pressure change drives the detection rod 512 to rotate around the hinge plate 511, causing the conductive sheet 515 to slide on the arc-shaped resistor plate 516, thereby changing the resistance value of the second sliding rheostat in the detection circuit.

[0039] The PLC controller monitors the change of the resistance value in the detection circuit in real time. When it detects that the resistance value deviates from the normal range, it is determined that the tank body enters the arc part and the spraying may be uneven. At this time, after a certain period of time (5s, 5s is the time for the spraying head 55 to move from above to the detection position), the PLC controller controls the second electromagnetic ring 510 to be energized (the larger the current passing through the sliding rheostat, the larger the inclination direction of the detection wheel 514. The reason is that when the conductive sheet 515 slides on the arc-shaped resistor plate 516 in the direction away from the spraying head 55, the resistance of the second sliding rheostat in the detection circuit gradually decreases); Therefore, the larger the upward inclination angle of the spraying head 55 is required. The reason is that the larger the current passing through the sliding rheostat is, the larger the inclination direction of the detection wheel 514 is, that is, the more obvious the curvature change of the tank body surface is. At this time, in order to make the antirust paint evenly sprayed on the arc part of the tank body, a larger upward inclination angle of the spraying head 55 is required. This is because when the tank body surface transitions from a cylinder to an arc, if the spraying head 55 maintains the original angle for spraying, the paint will be unevenly sprayed at the arc, such as insufficient spraying amount in the arc area near the bottom of the tank body. By increasing the upward inclination angle of the spraying head 55, the spraying direction of the paint can be adjusted, so that the antirust paint can better fit the arc surface of the tank body, ensure uniform coverage of the paint, avoid spraying defects caused by the change of the tank body shape, and thus ensure the overall spraying quality; Therefore, the power supply to the second electromagnetic ring 510 is controlled by the PLC controller. Since the second electromagnetic ring 510 and the second permanent magnet ring 58 attract each other magnetically, the second permanent magnet ring 58 overcomes the elastic force of the second non-magnetic spring and drives the moving block to slide in the moving groove. As a result, the pushing ring 59 pushes the spraying head 55 to rotate upward (since the top end of the pushing ring 59 is hinged to the spraying head 55, and the spraying head 55 is connected to the annular spraying pipe 51 through a flexible adjustment pipe. The flexible adjustment pipe is relatively short, so it limits the position of the spraying head 55. However, due to the flexibility of the flexible adjustment pipe, it can fix the tail end of the spraying head 55. Therefore, when the pushing ring 59 pushes the spraying head 55 upward, only the front end of the spraying head 55 will flip upward), changing the spraying angle. The purpose of this design is to adjust the angle of the spraying head 55 according to the different shapes and sizes of the fire extinguisher tank bodies, ensure that the rust-proof paint can be evenly sprayed on the surface of the tank body, avoid the occurrence of spraying dead angles or over-thick or over-thin spraying, and improve the spraying quality and rust-proof effect.

[0040] The working principle of the drying mechanism 6 is similar to that of the spraying mechanism 5. Driven by the moving mechanism 7, the drying ring 61 moves up and down while rotating to evenly dry the sprayed fire extinguisher tank body. The second motor 432 drives the rotating shaft 433 to rotate, driving the support column 434 and the drying ring 61 to rotate, so that the drying heat can be evenly transferred to the surface of the tank body, ensuring that the rust-proof paint can be quickly dried and cured to form a good rust-proof layer.

[0041] When the fire extinguisher tank body has completed the spraying and drying processes, it enters the blanking process. The rotating plate 3 rotates driven by the first motor 2 (the preset rotation angle each time is 90 degrees). When the infrared ray emitted by the infrared ray emitter 437 is received by the infrared ray receiver 438, the PLC controller determines that the blanking groove 431 has rotated above the blanking port 435. At this time, the PLC controller controls the first electromagnetic ring 416 to cut off the power supply. The first permanent magnet ring drives the sliding piece 415 to slide downward under the action of the first non-magnetic spring 417, and the pressing piece 414 releases the fixation of the tank body. The tank body falls into the blanking groove 431 and then enters the conveying structure 436 through the blanking port 435 to complete the blanking process and wait for subsequent packaging or transportation.
