Description

Technical Field

[0001] This utility model relates to the field of paint spraying technology, specifically a fireproof paint spraying device. Background Technology

[0002] Fire-retardant coating spraying equipment is a mechanized device specifically designed for the efficient and uniform application of intumescent or non-intumescent fire-retardant coatings to the surface of building materials or equipment. It typically employs high-pressure airless spraying or air-assisted spraying technology, enabling the rapid formation of a continuous, dense fire-retardant coating. This significantly improves construction efficiency, coating uniformity, and material utilization, while reducing the limitations of manual application. Fire-retardant coatings are a key construction tool for achieving passive fire protection in industrial and building fire prevention projects.

[0003] A fire-retardant coating spraying device disclosed in Chinese Patent Publication No. CN217473887U uses a locking component to push and lock the fire door in place. When the fire door is moved by the conveyor belt, the fire door is sprayed through the nozzle on the spray head. Because the conveyor belt runs at a uniform speed, the fire door can be sprayed evenly, and the spraying component does not need to be held by hand, which can speed up the spraying efficiency.

[0004] However, the use of spraying equipment has certain limitations. When spraying materials, it is necessary to clamp and limit the material to ensure the stability of the spraying. However, the contact surface between the material and the clamping components cannot be fully and effectively sprayed, which affects the overall applicability of the spraying equipment and the uniformity of the spraying.

The top of the outer sides of the two second spray heads are fixedly connected to the bottom end of the pull ropes, and the end of the transmission pipe away from the pump is fixedly connected to the first spray head and the second spray head respectively.

[0009] Preferably, the clamping mechanism includes a drive gear rotatably connected to the center of the rear end inside the spraying chamber. A servo motor is provided at the rear end of the drive gear, and the drive gear is installed at the output shaft end of the servo motor. The upper and lower ends of the drive gear are interlocked with racks, and the front ends of the two racks are fixedly connected to the moving block.

[0010] Preferably, the rotating mechanism includes a motor fixedly connected to the center of the left moving block, a clamping plate installed on the output shaft end of the motor, and a clamping plate rotatably connected to the inner side of the right moving block.

[0012] Preferably, the movable cavity and the limiting plate have the same specifications.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This fire-retardant coating spraying device uses a clamping mechanism to drive a gear, which in turn moves a rack. The rack then pushes two sets of moving blocks inside the spraying chamber to move relative to each other, causing the clamps on the moving blocks to hold the material to be sprayed. When the motor starts, the clamps rotate the material, allowing for rapid material rotation. When the drive gear rotates counter-clockwise and the rack releases the clamps on the moving blocks, the drive gear drives the first chain disc to rotate synchronously. The first chain disc then drives the second chain disc via a chain, which in turn drives the second bevel gear via the first bevel gear. The threaded rod at the top of the second bevel gear rotates within the threaded cylinder, which in turn pushes the bracket to lift via a limiting plate, thus stably lifting the material to be sprayed. This allows for rapid spraying of both sides of the material, improving the uniformity of the overall coating and the overall practicality of the spraying device. Attached Figure Description

[0023] like Figure 1-5 As shown, this utility model has the following two specific embodiments.

[0024] Example 1

[0025] A fire-retardant coating spraying device includes a spraying chamber 1, a spraying mechanism at the top of the spraying chamber 1, a clamping mechanism at the center of the rear end of the spraying chamber 1, and moving blocks 5 on the left and right sides of the front end of the clamping mechanism. A rotating mechanism is installed inside the moving blocks 5.

[0026] A door 101 is installed at the front end of the spraying chamber 1. A controller 102 is installed at the bottom of the front end of the door 101. Guide cavities 103 are provided on the left and right sides of the bottom of the inside of the spraying chamber 1. A filter plate 104 is fixed to the top of the inside of the guide cavity 103. A discharge port 105 is fixed to the outside of the bottom of the guide cavity 103. The controller 102 can control and start the electrical equipment inside the spraying chamber 1. At the same time, the guide cavity 103 can collect the excess paint sprayed and discharge it through the discharge port 105 for recycling.

[0027] The spraying mechanism includes a paint tank 2 fixedly attached to the center of the top of the spraying chamber 1. A pump 201 is fixedly attached to the center of the bottom of the paint tank 2. A transmission pipe 202 is fixedly attached to the output end of the pump 201. Pull ropes 106 are fixedly attached to the left and right sides of the top of the inside of the spraying chamber 1. A first spray head 3 is fixedly attached to the center of the top of the inside of the spraying chamber 1. Second spray heads 301 are rotatably connected to the top of the left and right sides of the inside of the spraying chamber 1. The top of the outer sides of the two second spray heads 301 are fixedly attached to the bottom end of the pull ropes 106. The end of the transmission pipe 202 away from the pump 201 is fixedly attached to the first spray head 3 and the second spray head 301 respectively. When the pump 201 is started, paint can be input into the first spray head 3 and the second spray head 301 respectively through the transmission pipe 202, and the material is sprayed evenly through the first spray head 3 and the second spray head 301.

[0028] The clamping mechanism includes a drive gear 4 rotatably connected to the center of the rear end inside the spraying chamber 1. A servo motor is provided at the rear end of the drive gear 4. The output shaft of the servo motor is equipped with the drive gear 4. The upper and lower ends of the drive gear 4 are interlocked with racks 401. The front ends of the two racks 401 are fixedly connected to the moving blocks 5. When the drive gear 4 rotates, it can push the racks 401 to move. At this time, the two sets of racks 401 can drive the front moving blocks 5 to move relative to each other and adjust the distance between the two sets of moving blocks 5.

[0029] The rotating mechanism includes a motor 501 fixedly connected to the center of the left moving block 5. A clamping plate 502 is installed on the output shaft end of the motor 501. The clamping plate 502 is rotatably connected to the inner side of the right moving block 5. When the motor 501 is started, it can drive the clamping plate 502 to rotate. At this time, the clamping plate 502 can drive the clamped material to rotate rapidly.

[0030] Example 2

[0031] The difference from Embodiment 1 is that this embodiment discloses a lifting mechanism for lifting and placing materials after they have been released:

[0032] The lifting mechanism includes a first chain disc 6 coaxially fixed to the front end of a drive gear 4. A chain 601 is externally meshed with the first chain disc 6. A second chain disc 602 is internally meshed with the bottom end of the chain 601. A first bevel gear 603 is fixed to the front end of the second chain disc 602. A second bevel gear 604 is meshed with the top of the front end of the first bevel gear 603. A movable cavity 107 is formed at the center of the bottom end inside the spray booth 1. A threaded rod 605 is rotatably connected to the center of the bottom end inside the movable cavity 107. The bottom end of the threaded rod 605 is coaxially fixed with the second bevel gear 604. The threaded rod 605 is externally threaded to a threaded cylinder 606. A limiting plate 607 is fixedly attached to the top of the threaded cylinder 606. A bracket 608 is fixedly attached to the top of the limiting plate 607. When the drive gear 4 rotates, it can drive the first chain disc 6 to rotate synchronously. At this time, the first chain disc 6 can drive the second chain disc 602 to rotate through the chain 601. Then, the first bevel gear 603 at the front end of the second chain disc 602 can drive the threaded rod 605 to rotate inside the threaded cylinder 606 through the second bevel gear 604. At this time, the threaded cylinder 606 can drive the bracket 608 to move up and down through the limiting plate 607.

[0033] The movable cavity 107 has the same specifications as the limiting plate 607. In addition, all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] In this embodiment, the material to be sprayed is placed at the center of the two sets of moving blocks 5. The drive gear 4 rotates, causing the rack 401 to move. The rack 401 then moves the moving blocks 5, and the clamping plates 502 inside the two sets of moving blocks 5 clamp the material. Simultaneously, the drive gear 4 rotates the first chain disc 6, which in turn rotates the second chain disc 602 via the chain 601. The first bevel gear 603 at the front end of the second chain disc 602 then rotates the threaded rod 605 within the threaded cylinder 606 via the second bevel gear 604. The threaded cylinder 606 then rotates the bracket via the limiting plate 607. 608 moves downwards, and at the same time, the pump 201 in the paint tank 2 is started, which can input paint into the first spray head 3 and the second spray head 301 through the transmission pipe 202, and spray the material below. At the same time, the motor 501 in the moving block 5 is started, which can drive the clamped material to rotate quickly through the clamping plate 502, and perform material spraying work efficiently. After the initial spraying is completed, the drive gear 4 reverses, and at this time the two sets of moving blocks 5 can release the clamping of the material. At this time, the drive gear 4 drives the first chain 6 to reverse, and the bracket 608 can be quickly lifted and the material can be quickly lifted. At this time, the left and right sides of the material can be effectively sprayed.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
