Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rust-proof spraying, in particular to a rust-proof spraying treatment device for fire-fighting equipment. BACKGROUND

[0002] In the field of fire-fighting equipment, the rust-proof treatment of fire extinguisher tank bodies is of great importance. At present, the common rust-proof treatment methods for fire extinguisher tank bodies mainly include manual spraying and the use of traditional automatic spraying equipment. Manual spraying relies on manual operation of workers to evenly apply rust-proof paint on the surface of the tank body through a spray gun. Traditional automatic spraying equipment simulates manual spraying actions through a mechanical arm or the like to achieve rust-proof treatment of the tank body. The drying link 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 low in efficiency and difficult to meet large-scale production needs, but also greatly affected by the proficiency and working state of workers, which easily leads to uneven spraying, dead angles and other problems, resulting in poor rust-proof effect. Although traditional automatic spraying equipment improves efficiency to some extent, it cannot automatically adjust the spraying angle according to the shape and size of the fire extinguisher tank body. When treating the arc-shaped part of the tank body, uneven spraying will also occur, thereby affecting the rust-proof performance and service life of the tank body and increasing maintenance costs and safety hazards.

[0045] The working principle of the present application is as follows:

[0046] When the device is used for rust-proof spraying treatment of the fire extinguisher tank body, the automatic feeding, fixing the tank body, spraying the rust-proof paint, drying treatment and automatic unloading are sequentially performed in order, so that the automation and high efficiency of the rust-proof treatment of the fire extinguisher tank body are realized.

[0047] Firstly, the fire extinguisher tank body is carried from the placing frame 421 to the fixing assembly 41 through the feeding assembly 42, the placing frame 421 is used for storing the fire extinguisher tank body to be treated, the clamping groove 422 at the discharge end of the placing frame 421 is convenient for the automatic clamping device 4212 to grab the tank body, the third motor 423 drives the rotating rod 424 and the rotating plate 425 to rotate, so that the automatic clamping device 4212 can rotate to facilitate clamping and placing the fire extinguisher tank body, the fourth motor 427 drives the threaded rod 428 to rotate, the threaded block 429 slides up and down in the lifting groove 426, so as to adjust the height of the automatic clamping device 4212, when the automatic clamping device 4212 moves to the appropriate position, the fifth motor 4210 adjusts the angle of the electric telescopic rod 4211, the electric telescopic rod 4211 is elongated, the automatic clamping device 4212 grabs the fire extinguisher tank body, and then carries the tank body to the fixing assembly 41 (all the above are controlled by the PLC controller, and the large wind program in the PLC controller is pre-set).

[0048] The fixed assembly 41 is fixed by extrusion from the inside of the fire extinguisher tank. When the fire extinguisher tank is placed on the connecting disc 411, the PLC controller controls the first electromagnetic ring 416 to be powered. Since the first electromagnetic ring 416 repels the first permanent magnet ring, the first permanent magnet ring drives the sliding piece 415 to slide upward, and then the second connecting rod 413 pulls the first connecting rod 412, and the first connecting rod 412 drives the extrusion piece 414 to move to the inside of the tank, and the tank is tightly extruded and fixed from the inside, so that the tank does not shake during the subsequent processing.

[0049] In the spraying mechanism 5, the material extraction pump 57 delivers the rust-proof paint to the annular spraying pipe 51 through the annular rotating pipe 56, and then the spraying head 55 on the inner wall of the annular spraying pipe 51 sprays out, sprays the fire extinguisher tank, and the sixth motor 71 drives the reciprocating screw rod 72 to rotate. The reciprocating block 74 is limited by the reciprocating screw rod 72 and the limiting rod 73, and moves linearly along the reciprocating screw rod 72. At the same time, since the gear 78 is engaged with the first tooth 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 in all directions and without dead angle.

[0050] 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 from top to bottom together with the annular spraying pipe 51 and the first fixed ring 54. When the tank enters the arc-shaped part from the cylindrical part, the curvature of the surface of the tank changes, and when the detection wheel 514 contacts the surface of the tank, the pressure received by the detection wheel 514 changes, and the change in pressure drives the detection rod 512 to rotate around the hinged plate 511, so that the conductive sheet 515 slides on the arc-shaped resistance plate 516, thereby changing the resistance value of the second sliding resistor in the detection circuit.

[0051] The PLC controller monitors the change of the resistance value in the detection circuit in real time. When the resistance value deviates from the normal range, it is judged that the tank enters the arc-shaped part and the spraying may be uneven. At this time, the PLC controller controls the second electromagnetic ring 510 to be powered after a period of time (5s, 5s is the time for the spraying head 55 to move from the top to the detection position). The greater the current through the sliding resistor, the greater the direction of the inclination of the detection wheel 514, because the conductive sheet 515 slides on the arc-shaped resistance plate 516 in the direction away from the spraying head 55, and the resistance of the second sliding resistor in the detection circuit gradually decreases.

[0052] Therefore, the greater the upward inclination angle of the spraying head 55, the greater the current through the sliding rheostat, which means that the greater the inclination direction of the detection wheel 514, that is, the more obvious the curvature change of the surface of the tank body. At this time, in order to uniformly spray the anti-rust paint on the arc-shaped part of the tank body, it is necessary to incline the spraying head 55 at a larger angle. This is because when the surface of the tank body transitions from a cylinder to an arc, if the spraying head 55 maintains the original angle for spraying, the paint will not be uniformly sprayed at the arc-shaped area, such as the arc-shaped area near the bottom of the tank body. By increasing the upward inclination angle of the spraying head 55, the direction of paint spraying can be adjusted to allow the anti-rust paint to better adhere to the arc-shaped surface of the tank body, ensuring uniform coverage of the paint and avoiding spraying defects caused by changes in the shape of the tank body, thereby ensuring the overall spraying quality.

[0053] Therefore, the second electromagnetic ring 510 is controlled by the PLC controller to control the amount of current. Since the second electromagnetic ring 510 is magnetically attracted to the second permanent magnet ring 58, the second permanent magnet ring 58 overcomes the elastic force of the second non-magnetic spring, drives the moving block to slide in the moving groove, and then drives the push ring 59 to push the spraying head 55 upward (since the top end of the push 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 adjusting pipe, which is relatively short, so it limits the position of the spraying head 55. However, since the flexible adjusting pipe is flexible, the flexible adjusting pipe can fix the tail end of the spraying head 55, so when the push ring 59 pushes the spraying head 55 upward, only the front end of the spraying head 55 is flipped upward), thereby 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 body, to ensure that the anti-rust paint can be uniformly sprayed on the surface of the tank body, to avoid dead angles or over-thin or over-thick spraying, and to improve the spraying quality and anti-rust effect.

[0054] The working principle of the drying mechanism 6 is similar to that of the spraying mechanism 5. The drying ring 61 is driven by the moving mechanism 7 to move up and down while rotating, thereby uniformly drying the sprayed fire extinguisher tank body. The second motor 432 drives the rotating shaft 433 to rotate, thereby driving the support column 434 and the drying ring 61 to rotate, so that the drying heat can be uniformly transmitted to the surface of the tank body, thereby ensuring that the anti-rust paint can be quickly dried and solidified to form a good anti-rust layer.

[0055] When the fire extinguisher tank is completed with spraying and drying, it enters the discharging process. The rotating plate 3 is rotated (with a rotation angle of 90 degrees each time) under the driving of the first motor 2. When the infrared rays emitted by the infrared emitter 437 are received by the infrared receiver 438, the PLC controller determines that the discharging groove 431 has been rotated to above the discharging port 435. At this time, the PLC controller controls the first electromagnetic ring 416 to be powered off. The first permanent magnet ring drives the sliding sheet 415 to slide downward under the action of the first non-magnetic spring 417. The pressing sheet 414 loosens the fixation on the tank body, and the tank body falls into the discharging groove 431. Subsequently, it enters the conveying structure 436 through the discharging port 435, and the discharging process is completed, waiting for subsequent packaging or transportation.
