Description

A spraying device for processing box-shaped columns Technical Field

[0001] This utility model relates to the field of box-shaped column processing technology, specifically a spraying device for box-shaped column processing. Background Technology

[0002] Box columns are columns with hollow cross sections, typically rectangular or square in shape. They have strong compressive and bending resistance and are commonly used in the construction, machinery, and automotive industries. After production, box columns require a spraying device to apply paint to their surface to protect them from corrosion.

[0003] Traditional spraying equipment for box-shaped column processing requires manual adjustment of the column's position and is inconvenient for spraying multiple columns at once, resulting in low efficiency. Therefore, we propose a spraying device for box-shaped column processing to address these issues. Summary of the Invention

[0004] The purpose of this invention is to provide a spraying device for processing box-shaped columns, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a spraying device for processing box-shaped columns, comprising a spray box, a door hinged to the front end of the spray box, a paint tank installed on one side of the spray box, a material pump installed at the top of the paint tank, a suction pipe installed at the bottom of the material pump extending into the interior of the paint tank, a conveying pipe installed on one side of the material pump, a spray pipe installed on one side of the conveying pipe, the spray pipe being located on the left side inside the spray box, a nozzle installed on one side of the spray pipe, a fixing frame installed on the outer wall of the spray pipe, a fixing block installed on one side of the fixing frame, and one side of the fixing block being fixed to the inner wall of the spray box, a rotating gear disk installed at the bottom of the inside of the spray box, a large gear movably arranged at the middle position inside the rotating gear disk, small gears arranged on the outer wall of the large gear, a first servo motor installed at the top of each small gear, a placement plate installed at the top of each first servo motor, a second servo motor installed at the bottom of the large gear, and a mounting base installed on the outer wall of the second servo motor.

[0006] Preferably, a plurality of nozzles are provided, and the plurality of nozzles are distributed at equal intervals on one side of the nozzle pipe.

[0007] Preferably, the pinion gears are provided in four sets, and the four sets of pinion gears mesh with the large gear and the rotating gear disk.

[0008] Preferably, a connecting block is installed at the top of each of the placement plates, and a first threaded rod is movably disposed inside each of the connecting blocks, with a limit block installed on one side of each first threaded rod.

[0009] Preferably, the first threaded rod and the connecting block form a threaded connection, and two sets of limiting blocks are provided.

[0010] Preferably, a second threaded rod is movably provided at the top of the rear end of the door body, and a third servo motor is installed on one side of the second threaded rod. A sliding rod is movably provided at the bottom of the rear end of the door body, and scraper rods are movably provided on the outer walls of both the second threaded rod and the sliding rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the spraying device for processing box-shaped columns not only greatly increases the processing efficiency and achieves better spraying effect, but also realizes automatic wiping and cleaning of the inner surface of the door.

[0014] (1) By setting a first servo motor, a rotating gear, a large gear and a small gear at the bottom of the spray box, and setting four sets of small gears, the cooperation of the above components can spray the four sets of box columns together. At the same time, the first servo motor can also drive the placement plate to rotate, causing the box columns above the placement plate to rotate, thus facilitating the spraying of different surfaces of the four sets of box columns, greatly increasing the processing efficiency.

[0015] (2) By setting up components such as limit blocks, connecting blocks and first threaded rods above the placement plate, after the box-shaped column to be sprayed is placed above the placement plate, the cooperation of the above components can push the limit blocks to fit against both sides of the box-shaped column to limit the box-shaped column, so that it is stably placed above the placement plate for spraying. The spraying process is more stable and the spraying effect is better.

[0016] (3) The spraying device is protected by a door when spraying. If the surface of the door is dirty and it is inconvenient to observe the spraying inside the spray box, the inner surface of the door can be wiped clean by the scraper, the second threaded rod and the sliding rod when the spray box is working, so that the door can be clear and the work can be better observed.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4. This utility model provides an embodiment: a spraying device for processing box-shaped columns, including a spray box 1. A door 18 is hinged to the front end of the spray box 1. A paint tank 2 is installed on one side of the spray box 1. A material pump 4 is installed at the top of the paint tank 2, and a suction pipe 3 is installed at the bottom end of the material pump 4, extending into the interior of the paint tank 2. A conveying pipe 6 is installed on one side of the material pump 4, and a spray pipe 5 is installed on one side of the conveying pipe 6. The spray pipe 5 is located on the left side inside the spray box 1. A nozzle 17 is installed on one side of the spray pipe 5. A fixing frame 8 is installed on the outer wall of the spray pipe 5. A fixing block 7 is installed on one side of the fixing frame 8, and one side of the fixing block 7 is fixed to the inner wall of the spray box 1. The bottom end of the spray box 1... A rotating gear disk 10 is installed, with a large gear 21 movably positioned in the middle of the rotating gear disk 10. Small gears 20 are provided on the outer side walls of the large gear 21, and a first servo motor 11 is installed on the top of each small gear 20. A placement plate 9 is installed on the top of each first servo motor 11. A second servo motor 12 is installed at the bottom of the large gear 21, and a mounting base 13 is installed on the outer side wall of the second servo motor 12. Several nozzles 17 are provided, and the nozzles 17 are evenly distributed on one side of the spray pipe 5 to spray the paint evenly. Four sets of small gears 20 are provided, and the four sets of small gears 20 mesh with the large gear 21 and the rotating gear disk 10, so that four sets of box-shaped columns can be sprayed at one time.

[0024] Specifically, as shown in Figures 1 and 3, the second servo motor 12 is started to drive the large gear 21 to rotate. The rotation of the large gear 21 causes the small gear 20 meshing with it to rotate inside the rotating gear disk 10, which sequentially transports each group of box-shaped columns above the placement plate 9 to one side of the spray head 17 for spraying. At the same time as the small gear 20 transports the box-shaped columns, the first servo motor 11 is started to drive the placement plate 9 to rotate, so that the spray head 17 can perform comprehensive spraying on different surfaces of the four groups of box-shaped columns.

[0025] Each of the top of the placement plate 9 is equipped with a connecting block 15. Each of the connecting blocks 15 has a first threaded rod 16 movably installed inside it. Each of the first threaded rods 16 has a limit block 14 installed on one side. The first threaded rod 16 and the connecting block 15 form a threaded connection. There are two sets of limit blocks 14. Pushing the limit blocks 14 to move stably limits the box-shaped column.

[0026] Specifically, as shown in Figures 1 and 2, the box-shaped column is placed on top of the four sets of placement plates 9 in sequence. Then, the first threaded rods 16 on both sides of the upper part of the placement plate 9 are rotated in sequence. The first threaded rods 16 rotate and push the limiting blocks 14 to fit against the two sides of the box-shaped column to clamp it, so that the box-shaped column is stably placed on top of the placement plate 9.

[0027] A second threaded rod 22 is movably provided at the top of the rear end of the door body 18, and a third servo motor 23 is installed on one side of the second threaded rod 22. A sliding rod 24 is movably provided at the bottom of the rear end of the door body 18. Scraper rods 19 are movably provided on the outer walls of the second threaded rod 22 and the sliding rod 24. The top of the scraper rod 19 is uniformly provided with internal threads. The scraper rod 19 and the second threaded rod 22 form a threaded connection. The cross-section of the scraper rod 19 is larger than the cross-section of the sliding rod 24. The scraper rod 19 and the sliding rod 24 form a sliding structure, which drives the scraper rod 19 to move stably to scrape and clean the door body 18.

[0028] Specifically, as shown in Figures 2 and 4, when the spray box 1 is performing spraying work, if the inner surface of the door 18 gets dirty, the third servo motor 23 is activated to drive the second threaded rod 22 to rotate. The rotation of the second threaded rod 22 guides the scraper 19 through the sliding rod 24, causing the scraper 19 to move from one side of the inner surface of the door 18 to the other side to scrape and clean the inner surface of the door 18. This keeps the door 18 clean, making it easier to observe the spraying work inside the spray box 1 later.

[0029] Working principle: When using this utility model, open the door 18 to take out the box-shaped column and place it on top of the placement plate 9. Rotate the first threaded rods 16 on both sides of the top of the placement plate 9 in sequence. The rotation of the first threaded rods 16 pushes the limiting blocks 14 to fit against both sides of the box-shaped column and clamp it, so that the box-shaped column is stably placed on top of the placement plate 9. Then, turn on the material pump 4 to draw out the paint inside the paint tank 2 through the extraction pipe 3 and transport it to the inside of the spray pipe 5 through the conveying pipe 6, and then spray it out through the nozzle 17. Then, start the second servo motor 12 to drive the large gear 21 to rotate. The rotation of the large gear 21 causes the small gear 20 meshing with it to rotate inside the rotating gear disk 10, sequentially conveying each group of box-shaped columns above the placement plate 9 to one side of the spray head 17 for spraying. While the small gear 20 is conveying the box-shaped columns, the first servo motor 11 starts and drives the placement plate 9 to rotate, allowing the spray head 17 to perform comprehensive spraying on different surfaces of the four groups of box-shaped columns until the box-shaped columns are finished being sprayed. Then, the door 18 is opened and the first threaded rod 16 is rotated in reverse to move the limiting block 14 and open the limiting of the box-shaped columns, allowing the box-shaped columns to be removed.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
