Description

Technical Field

[0001] This utility model relates to the field of coating machines, and in particular to an automatic coating machine for building construction. Background Technology

[0002] With the acceleration of industrialization, steel structure workshops have been widely used in the construction field. Due to their superior strength, durability, and ease of construction, steel structures are widely used in various factories, warehouses, and large buildings. However, steel is exposed to the air for a long time and is easily affected by natural environmental factors such as oxidation and corrosion, leading to rust on the surface of the steel structure, which in turn affects its service life and safety. Therefore, rust prevention treatment of steel structures is particularly important. At present, the construction of rust-proof coatings for steel structures mainly relies on manual spraying or brushing, which is relatively inefficient. In order to improve coating efficiency, ensure coating quality, reduce paint waste, and ensure the safety of construction workers, some automated coating equipment has begun to enter the market in recent years. Therefore, an automatic coating machine for building construction is proposed.

[0003] Traditional painting machines, after applying anti-corrosion paint to the steel structure support of the factory roof, require workers to manually wrap the paint-flowing nozzle around the outer wall of the machine. This is more cumbersome than automatic winding, and the nozzles of these machines are generally quite long, further increasing the workload for workers. Additionally, if the paint remains stagnant inside the machine for an extended period, it will not atomize evenly when sprayed through the spray gun, and air bubbles may appear on the surface of the steel structure after spraying, reducing the paint's anti-corrosion performance. Furthermore, most existing painting machines cannot effectively remove residual paint from the inner walls, leading to significant paint waste during cleaning.

[0004] To address the shortcomings of existing technologies, this utility model provides an automatic painting machine for building construction. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic painting machine for construction. This machine uses a geared motor to drive a auger roller to rotate slowly, thereby moving the paint liquid inside the roller slowly. This avoids problems such as uneven atomization or air bubbles after spraying, which reduce the anti-corrosion effect, caused by the paint not flowing. Then, the engagement of the drive gear and driven gear rotates the second reciprocating screw, causing a scraper to remove residual paint from the inner wall of the storage tank, preventing excessive paint buildup and waste during cleaning.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An automatic painting machine for building construction includes a storage box. A winding mechanism is provided on the upper surface of the storage box. The winding mechanism includes support plates fixedly connected to both sides of the front end of the upper surface of the storage box. A servo motor is fixedly connected to one outer wall of the support plate. A first reciprocating screw is fixedly connected to the output end of the servo motor. The other end of the first reciprocating screw passes through the support plate and is fixedly connected to a drive disc. Side plates are provided at the rear ends of the support plates. A winding roller is rotatably connected to the inner wall of each side plate. One end of the winding roller passes through the side plate and is fixedly connected to a driven disc. A transmission belt is sleeved on the outer wall of both the drive disc and the driven disc.

[0008] The storage box is equipped with an anti-condensation mechanism. The anti-condensation mechanism includes a U-shaped frame fixedly connected to the outer wall of the front end of the storage box, a reduction motor fixedly connected to the inner wall of the front end of the U-shaped frame, a drive gear fixedly connected to the output end of the reduction motor, a storage slot opened inside the storage box, an auger roller arranged in the middle of the storage slot, a second reciprocating screw arranged on both sides of the auger roller, a second slider sleeved on the shaft of the second reciprocating screw, and a scraper fixedly connected to the outer wall of the side of the second slider away from the auger roller.

[0009] The above technical solution, with its anti-condensation mechanism inside the storage tank and driven by a geared motor, along with components such as the drive gear and auger roller, effectively prevents the paint from solidifying inside the storage tank, ensuring paint flowability and smooth painting operations. This significantly improves the stability and reliability of the painting machine, reducing malfunctions. Furthermore, the winding mechanism, composed of a servo motor and a first reciprocating screw, enables automatic winding, greatly reducing the complexity of manual operation and enhancing the overall automation of the construction process.

[0010] Furthermore, a conveying pump is fixedly connected to the middle of the rear end of the upper surface of the storage box. The input end of the conveying pump is connected through the storage tank. The output end of the conveying pump is fixedly connected to a conveying pipe. The end of the conveying pipe away from the conveying pump passes through a side plate and is rotatably connected to the outer wall of a side of the winding roller. A nozzle is connected through the roller body of the winding roller.

[0011] Through the above technical solution, the paint liquid in the storage tank can be better transported to the inside of the delivery pipe by the delivery pump, and then transported to the inside of the take-up roller through the delivery pipe, and then flowed into the inside of the spray pipe. Furthermore, the rotational connection between the delivery pipe and the center of the outer wall of the take-up roller can effectively prevent the delivery pipe from curling.

[0012] Furthermore, the outer wall of the front end of the auger roller passes through the storage groove and is fixedly connected to the driving gear. Driven gears are provided on both sides of the driving gear. The front end of the second reciprocating screw passes through the storage groove and is fixedly connected to the driven gear. The driving gear and the driven gear are meshed together.

[0013] Through the above technical solution, the meshing of the driving gear and the driven gear can better enable the geared motor to drive the second reciprocating screw to rotate, thereby moving the scraper to treat the paint residue on both sides of the storage tank.

[0014] Furthermore, each of the front outer walls of the support plate is fixedly connected to a mounting plate, each of the inner walls of the mounting plate is fixedly connected to a movable rod, each movable rod is slidably connected to a movable block, the rear outer wall of the movable block is fixedly connected to a first slider, and a limit frame is fixedly connected to the upper surface of the first slider.

[0015] The above technical solution, through the movable rod and movable block, can better limit the first slider, and at the same time, the first slider drives the limiting frame to move, which can better guide the nozzle.

[0016] Furthermore, both sides of the inner wall at the front end and both sides of the inner wall at the rear end of the storage tank are fixedly connected to limit rods, the rods of the limit rods are slidably connected to limit blocks, and the lower surfaces of the limit blocks are fixedly connected to the second slider.

[0017] Through the above technical solution, the limiting rod and the limiting block can better limit the movement of the second slider on the second reciprocating screw, thereby enabling the scraper to move more stably.

[0018] Furthermore, a movable seat is fixedly connected to the lower surface of the storage box;

[0019] The above technical solution, through the installation of a movable seat, allows the painting machine to be moved more easily by the tires on the movable seat.

[0020] Furthermore, push handles are fixedly connected to both sides of the rear end of the upper surface of the storage box;

[0021] The above technical solution, through the setting of the push plate, allows the coating machine to be moved more effectively by the push handle when necessary.

[0022] Furthermore, a feeding hopper is fixedly connected to one side of the middle of the upper surface of the storage box, and the feeding hopper is connected in a through manner to the storage tank;

[0023] The above technical solution allows for easier filling of the storage tank with an appropriate amount of paint before construction, thus facilitating subsequent painting work.

[0024] This utility model has the following beneficial effects:

[0025] 1. The present invention proposes an automatic painting machine for building construction. When the first reciprocating screw is rotated by a servo motor, the active disc rotates, and then the winding roller is rotated by a transmission belt, thereby winding the spray nozzle. At the same time, the first slider drives the limiting frame to move, thereby guiding the spray nozzle and avoiding the spray nozzle being concentrated in the winding roller body. In addition, the automatic winding mechanism can effectively reduce the labor intensity of workers when winding the spray nozzle.

[0026] 2. The automatic painting machine for building construction proposed in this utility model uses a geared motor to drive the auger roller to rotate slowly, thereby driving the paint liquid inside the auger roller to move slowly. This avoids the problem of uneven atomization or the formation of bubbles after spraying, which reduces the anti-corrosion effect, due to the paint liquid not flowing. Then, the second reciprocating screw is rotated by the meshing of the drive gear and the driven gear, so that the scraper scrapes off the paint liquid remaining on the inner wall of the storage tank, avoiding the problem of excessive paint liquid on the inner wall during cleaning and thus avoiding waste.

The rear outer wall of the movable blocks 408 is fixedly connected to the first slider 411. A limiting frame 412 is fixedly connected to the upper surface of the first slider 411. Through the movable rods 413 and the movable blocks 408, the first slider 411 can be better limited. At the same time, the first slider 411 drives the limiting frame 412 to move, which can better guide the nozzle 9.

The rod body of the limiting rod 307 is slidably connected to the limiting block 308. The lower surface of the limiting block 308 is fixedly connected to the second slider 310. Through the limiting rods 307 and the limiting blocks 308, the second slider 310 is better limited when it moves on the second reciprocating screw 305, so that the scraper 304 can move more stably.

[0046] Reference Figure 1 The lower surface of the storage box 2 is fixedly connected to a movable seat 1. The movable seat 1 allows the painting machine to be moved more easily by the tires on the movable seat 1. Push handles 6 are fixedly connected to both sides of the rear end of the upper surface of the storage box 2. The push handles 6 allow the painting machine to be moved more easily when necessary. A feed hopper 8 is fixedly connected to one side of the middle of the upper surface of the storage box 2. The feed hopper 8 is connected to the storage tank 10. The feed hopper 8 allows an appropriate amount of paint to be poured into the storage tank 10 more easily before construction, which facilitates the subsequent painting work.

[0047] Working Principle: During operation, paint is injected into the storage tank 2 through the feed hopper 8. The coating machine is then moved to the designated position and powered on. The rewinding mechanism 4 reverses to release the spray nozzle 9. During spraying, the conveying pump 7 draws paint from the storage tank 10, which enters the spray nozzle 9 through the conveying pipe 5. The paint is then atomized and sprayed onto the outer wall of the steel structure support through the spray gun. During spraying, the reduction motor 302 drives the drive gear 309 to rotate, which in turn drives the auger roller 306 to rotate slowly, causing the paint inside to flow slowly. Simultaneously, the drive gear 309 meshes with the driven gear 303, causing the driven gear 303 to drive the second reciprocating screw 305 to rotate. Then, through… The rotation of the second reciprocating screw 305 causes the second slider 310 to move the scraper 304, scraping away the paint on the inner wall of the storage tank 10 while also allowing the paint to move slowly. After the spraying is completed, the servo motor 406 is started, causing the servo motor 406 to rotate the first reciprocating screw 409. The rotation of the first reciprocating screw 409 causes the first slider 411 to move the limiting frame 412, guiding the nozzle 9. At the same time as the first reciprocating screw 409 rotates, the drive disc 401 drives the driven disc 403 to rotate through the transmission belt 402. The different ratio of the drive disc 401 and the driven disc 403 causes the take-up roller 405 to rotate more slowly, thus performing the take-up operation on the nozzle 9 by rotating the take-up roller 405.
