Description

Technical Field

[0001] This utility model relates to the field of steel plate surface spraying technology, and in particular to an automatic spraying device based on the surface of ultra-fine grain reinforced steel plate. Background Technology

[0002] Steel plate surface spraying is a common surface treatment process designed to enhance its corrosion resistance, wear resistance, and aesthetics. These processes not only improve the performance of steel plates but also expand their application range in industrial and construction fields. With continuous technological advancements, future steel plate surface spraying processes will become more environmentally friendly and efficient, providing higher-quality material solutions for various industries.

[0003] Chinese utility model patent document (Announcement No.: CN118950321A) discloses an automatic spraying device and method based on the surface treatment of ultrafine-grained reinforced steel plates. The device includes a water tank base for absorbing paint dust during spraying and preventing it from remaining in the air. A partition bolt is bolted to the top of the water tank base to isolate the spraying space from the bottom space. A reciprocating spraying mechanism is used to rapidly spray the surface of the steel plate being transported at the bottom, improving spraying efficiency. Guide components are provided on both sides of the steel plate to guide it and prevent deviation. An agitation structure is installed inside the bottom water tank to allow the water inside the base to move, thereby adhering the paint dust remaining in the air through the dispersed water vapor, which then falls to the bottom, preventing prolonged exposure to the air and potential health hazards to workers.

[0004] However, in the aforementioned patents, the dust generated during spraying is carried into the water by agitated water vapor. While this effectively removes the dust, it requires a significant amount of water, leading to unnecessary waste of water resources. Therefore, we propose an automatic spraying device based on the surface of ultra-fine grain reinforced steel plates to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem that when dealing with dust generated during spraying, the dust is carried into the water by agitation of water vapor. Although the dust is treated, a certain amount of water is required, which leads to unnecessary waste of water resources. Therefore, an automatic spraying device based on the surface of ultra-fine grain reinforced steel plate is proposed.

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

[0007] An automatic spraying device for the surface of ultrafine-grained reinforced steel plates includes a vertically arranged support, two conveyor rollers disposed within the support, and a conveyor belt drivenly connected to the two conveyor rollers. It also includes:

[0008] The top box is fixedly installed at the center position between the two sides of the top of the bracket. The front of the top box is equipped with a controller and an observation window.

[0009] The dust collection mechanism includes two exhaust fans symmetrically fixedly installed on the top box. Each exhaust fan is connected to a connecting pipe. One end of each connecting pipe is connected to a transfer box fixedly installed on the top surface of the top box and located between the two exhaust fans. A positioning ring is fixedly installed on one side of the transfer box, and a collection bag is provided on one side of the transfer box. The collection bag can collect dust in the airflow.

[0010] The disassembly mechanism is located on one side of the transfer box, which facilitates the disassembly or installation of the collection bags.

[0011] Furthermore, a conveyor motor is fixedly installed on one vertical surface of the bracket, and the output shaft of the conveyor motor is fixedly connected to one of the conveyor rollers.

[0012] Furthermore, a reciprocating motor is fixedly installed on one side of the top box, and a rotating rod is rotatably connected inside the top box. The output shaft of the reciprocating motor is fixedly connected to the rotating rod, and a reciprocating lead screw is fixedly connected to the rotating rod. A limit plate is slidably connected in the reciprocating groove of the reciprocating lead screw, and a spraying plate is fixedly connected to the bottom end of the limit plate. The limit plate moves back and forth with the reciprocating groove of the reciprocating lead screw, and drives the spraying plate to move back and forth for spraying.

[0013] Furthermore, a limiting groove is provided on the top wall of the top box, and the top end of the limiting plate slides within the limiting groove.

[0014] Furthermore, the disassembly mechanism includes a ring fixedly installed on one side of the transfer box, and a discharge port is provided on one side of the transfer box located inside the ring. A collection bag is fitted onto the discharge port. Multiple fixed pressure rods are symmetrically slidably connected on the ring. A return spring is fitted on the fixed pressure rod. A wedge block is fixedly connected to one end of the fixed pressure rod. The wedge block is fixedly connected to one end of the return spring. When the wedge block moves, it can compress the return spring. Conversely, when the return spring releases its elastic force, it can drive the wedge block to move and reset.

[0015] Furthermore, inclined plates that cooperate with multiple inclined blocks are symmetrically fixedly installed inside the positioning ring. When the positioning ring rotates, the multiple inclined plates can make a circular motion and squeeze the multiple inclined blocks closer to each other.

[0016] Furthermore, the outer ring of the positioning ring is provided with multiple positioning grooves, and a sliding groove is provided vertically on one side of the transfer box above the positioning ring. A sliding plate is slidably connected in the sliding groove, and a positioning pin is fixedly connected to the bottom of the sliding plate. The bottom end of the positioning pin is located in one of the positioning grooves. The cooperation between the positioning pin and the positioning groove can achieve the effect of fixing the positioning ring.

[0017] Compared with the prior art, the advantages of this utility model are:

[0018] 1. In this solution, two exhaust fans extract the dust generated during spraying from the top box and transport it to the transfer box through two connecting pipes. Then, with the airflow, the dust enters the collection bag through the exhaust port, thus achieving the effect of dust collection.

[0019] 2. In this solution, the staff lifts the slide plate upwards, causing the positioning pin to disengage from the positioning groove. At the same time, multiple return springs release their elasticity, causing multiple inclined blocks to move outwards and multiple fixed pressure rods to move away from the collection bag. Then, the collection bag is removed from the discharge port, thus quickly completing the disassembly of the collection bag and treating the dust inside.

[0020] This utility model has a simple structure. It uses a fan to extract dust and transport it to a collection bag to complete the dust collection and treatment. It also allows for the disassembly of the collection bag, avoiding waste of resources and making it convenient for people to use. Attached Figure Description

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.

[0029] Example 1

[0030] Reference Figures 1-4 An automatic spraying device for the surface of ultrafine-grained reinforced steel plates includes a vertically arranged support 1, two conveyor rollers disposed within the support 1, and a conveyor belt 26 drivenly connected to the two conveyor rollers. It also includes:

[0031] The top box 2 is fixedly installed at the center position between the two sides of the top of the bracket 1. The front side of the top box 2 is equipped with a controller 3, and the top box 2 is equipped with an observation window 27. The observation window 27 is set so that the staff can observe the spraying of steel plates inside the top box 2. A conveyor motor 25 is fixedly installed on one vertical surface of the bracket 1, and the output shaft of the conveyor motor 25 is fixedly connected to one of the conveyor rollers.

[0032] In this embodiment, a reciprocating motor 18 is fixedly installed on one side of the top box 2, and a rotating rod 19 is rotatably connected inside the top box 2. The output shaft of the reciprocating motor 18 is fixedly connected to the rotating rod 19. A reciprocating lead screw 20 is fixedly connected to the rotating rod 19. A limiting plate 22 is slidably connected in the reciprocating groove of the reciprocating lead screw 20. A spraying plate 23 is fixedly connected to the bottom end of the limiting plate 22. The limiting plate 22 moves back and forth with the reciprocating groove of the reciprocating lead screw 20, and drives the spraying plate 23 to move back and forth for spraying. A limiting groove 21 is provided on the top wall of the top box 2. The top end of the limiting plate 22 slides in the limiting groove 21. The limiting groove 21 can limit the movement trajectory of the limiting plate 22, so that it keeps moving horizontally.

[0033] In this embodiment, the dust collection mechanism includes two exhaust fans 4 symmetrically fixedly installed on the top box 2. Each exhaust fan 4 is connected to a connecting pipe 5. One end of each connecting pipe 5 is connected to a transfer box 6 fixedly installed on the top surface of the top box 2 and located between the two exhaust fans 4. A positioning ring 7 is fixedly installed on one side of the transfer box 6, and a collection bag 24 is provided on one side of the transfer box 6. The collection bag 24 can collect dust in the airflow. A disassembly mechanism is located on one side of the transfer box 6 to facilitate the disassembly or installation of the collection bag 24. The disassembly mechanism includes a component fixedly installed on the transfer box 6... The side ring 10, and the transfer box 6 is located inside the ring 10 with an outlet 9. The collection bag 24 is fitted onto the outlet 9. Multiple fixed pressure rods 11 are symmetrically slidably connected on the ring 10. The multiple fixed pressure rods 11 can move towards or away from the outlet 9 on the ring 10. A return spring 12 is fitted on the fixed pressure rod 11. One end of the fixed pressure rod 11 is fixedly connected to an inclined block 13. The inclined block 13 is fixedly connected to one end of the return spring 12. When the inclined block 13 moves, it can compress the return spring 12. Conversely, when the return spring 12 releases its elastic force, it can drive the inclined block 13 to move and reset.

[0034] In this embodiment, inclined plates 14 that cooperate with multiple inclined blocks 13 are symmetrically fixedly installed inside the positioning ring 7. When the positioning ring 7 rotates, the multiple inclined plates 14 can make a circular motion and squeeze the multiple inclined blocks 13 closer to each other. The outer ring of the positioning ring 7 is provided with multiple positioning grooves 8. A sliding groove 15 is provided vertically on one side of the transfer box 6 above the positioning ring 7. A sliding plate 16 is slidably connected in the sliding groove 15. The setting of the sliding groove 15 allows the sliding plate 16 to slide only vertically. A positioning pin 17 is fixedly connected to the bottom of the sliding plate 16. The bottom end of the positioning pin 17 is located in one of the positioning grooves 8. The cooperation between the positioning pin 17 and the positioning groove 8 can achieve the effect of fixing the positioning ring 7.

[0035] The implementation principle of the automatic spraying device for the surface of ultra-fine grain reinforced steel plate in this application embodiment is as follows: First, the operator lifts the slide plate 16 upwards, causing the positioning pin 17 to disengage from the positioning groove 8. The collection bag 24 is then placed on the discharge outlet 9. By rotating the positioning ring 7, multiple inclined plates 14 make a circular motion and contact multiple inclined blocks 13, squeezing the multiple inclined blocks 13 and causing multiple fixed pressure rods 11 to move. At the same time, the return spring 12 is compressed. After the multiple fixed pressure rods 11 move a certain distance, they contact the bag, thus fixing the bag on the discharge outlet 9, achieving the desired effect. To assess the effectiveness of the collection bag 24 installation, the slide plate 16 is simultaneously released, allowing the slide plate 16 to utilize its vertical limit with the slide groove 15 to drive the positioning pin 17 to fall vertically and insert into one of the positioning slots 8, thereby completing the fixation of the positioning ring 7. The steel plate to be sprayed is placed on the conveyor belt 26, and the controller 3 is used to start the conveyor motor 25, causing the output shaft of the conveyor motor 25 to drive one of the conveyor rollers to rotate. Since the conveyor belt 26 is connected between the two conveyor rollers, the conveyor belt 26 can transport the steel plate. When one end of the steel plate is in the spraying position... When the plate is below 23, the reciprocating motor 18 is started, causing the output shaft of the reciprocating motor 18 to drive the rotating rod 19 to rotate. The rotating rod 19 drives the reciprocating screw 20 to rotate. The limiting plate 22 is limited by sliding between itself and the limiting groove 21. At the same time, it moves back and forth with the direction of movement of the reciprocating screw 20 in the reciprocating groove. The limiting plate 23 drives the spraying plate 23 to move back and forth quickly to spray the steel plate. At the same time, the two exhaust fans 4 draw the dust generated by spraying out of the top box 2 and transport it to the transfer box 6 through the two connecting pipes 5. Then, with the airflow, it enters the collection cloth through the exhaust port 9. The dust is collected inside the bag 24. When the dust inside the bag 24 needs to be treated, the operator lifts the slide plate 16 upwards and moves the positioning pin 17 out of the positioning groove 8. At the same time, multiple return springs 12 release their elastic force to move multiple inclined blocks 13 outwards. The multiple inclined blocks 13 can squeeze multiple inclined plates 14 away and move multiple fixed pressure rods 11 away from the collection bag 24. Then the collection bag 24 is removed from the discharge port 9, and the collection bag 24 is quickly disassembled and the dust inside the collection bag 24 is treated.

[0036] Example 2

[0037] The difference between Embodiment 2 and Embodiment 1 is that: an infrared sensor is provided on the top wall of the top box 2 next to the limiting groove 21, and a dust sensor is provided inside the top box 2. When the infrared sensor detects the steel plate, it sends a signal to the controller 3 to start the reciprocating motor 18 and the spraying plate 23 to perform the spraying work. When dust is generated inside the top box 2, the dust sensor is sensed and sends a signal to the controller 3, which then starts two exhaust fans 4 to remove the dust. All structures in this application can be selected in terms of material and length according to actual use. The attached drawings are schematic structural diagrams, and the actual dimensions can be adjusted appropriately.

[0038] The above description is only a preferred embodiment of this practice, but the scope of protection of this embodiment is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in this embodiment, based on the technical solution and the inventive concept of this embodiment, should be covered within the scope of protection of this embodiment.
