Description

Technical Field

[0001] This utility model relates to the field of metal powder coating technology, and more specifically, to a testing and spraying device for high-flexibility color steel plate powder coating. Background Technology

[0002] High-flexibility color steel plate powder coating usually refers to metal powder coatings with high flexibility and good adhesion. It is mainly used for the surface treatment of color steel plates to enhance their anti-corrosion, anti-rust and aesthetic effects.

[0003] After the production of metal powder coating is completed, the quality of the product after spraying the metal powder coating is generally required to conduct a preliminary inspection to determine whether the metal powder coating meets the requirements. This spraying process is generally carried out by manually holding the spray gun and spraying it onto the steel plate inside the open box. When using it, it is necessary to manually aim the spray gun at the steel plate, which increases the labor intensity of the workers.

[0004] A search revealed that Chinese patent CN208960215U discloses a powder coating test spraying device. It uses a first motor and a second motor to drive a steel plate mounting platform to rotate 360° along the circumference of the turntable, or rotate 360° on its own. The position of the steel plate can be adjusted according to the position of the spray gun. It is easy to use, requires no manual operation, and saves manpower.

[0005] In actual use, the steel plate of the above-mentioned metal powder coating test spraying device can only rotate 360° along the circumference of the turntable. For color steel plates that need to be sprayed on both sides, after one side is sprayed, the color steel plate is taken out, manually flipped, and then the other side is sprayed, which increases the spraying time and reduces the spraying efficiency. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a test spraying device for high-flexibility color steel plate powder coating, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A test spraying device for high-flexibility color steel plate powder coating includes a housing, a cabinet door installed on the front side of the housing, a cylinder fixedly connected to the top of the housing, a movable box fixedly connected to the output end of the cylinder, a spraying mechanism installed inside the movable box, two infrared heating tubes fixedly connected inside the housing, the two infrared heating tubes being symmetrically distributed inside the housing, and a clamping assembly installed inside the housing.

[0009] The clamping assembly includes a connecting box, which is fixedly connected to the interior of the outer shell. Two connecting rods are fixedly connected to the front side of the connecting box. Two sliding grooves are formed on the front side of the connecting rods, and sliding rods are slidably connected to the inner side of the sliding grooves. Two electric push rods are installed inside the connecting box. A clamping plate is fixedly connected to the output end of the electric push rod. A first rotating disk is rotatably connected to one side of one clamping plate, and a first stepper motor is fixedly connected to one side of the other clamping plate. A first gear is fixedly connected to the output end of the first stepper motor. A second gear meshes with one side of the first gear. A connecting shaft is fixedly connected inside the second gear. The connecting shaft is rotatably connected to the interior of the other clamping plate. A second turntable is fixedly connected to the outer side of the connecting shaft. Multiple anti-slip strips are fixedly connected to one side of both the second turntable and the first rotating disk.

[0010] By adopting the above technical solution, the color steel plate maintains a stable posture during the spraying process, which is conducive to improving the spraying quality.

[0011] As a further description of the above technical solution: the spraying mechanism includes a gear pump, the output end and input end of which are both connected to a connecting pipe. One end of one connecting pipe is connected to a paint tank, which is fixedly connected to one side of the movable box. One end of the other connecting pipe is connected to a diverter pipe, which is fixedly connected to the inside of the movable box. The bottom end of the diverter pipe is connected to two connecting hoses, one end of which is connected to a spraying pipe. The bottom end of the spraying pipe is connected to multiple spray heads. Two second stepper motors are fixedly connected to one side of the movable box. The output end of each second stepper motor is fixedly connected to a lead screw, which is rotatably connected to the inside of the movable box. A spraying housing is threaded onto the outside of the lead screw, and the inside of the spraying housing is fixedly connected to the spraying pipe.

[0012] By adopting the above technical solution, the two spraying shells move back and forth alternately, which allows the paint to be more evenly covered on the surface of the color steel plate.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. By setting up a clamping component, compared with the existing technology, the two clamping plates can clamp the color steel plate while the second turntable and the first flipping plate can rotate to flip the color steel plate, so that the color steel plate can be sprayed on both sides without manual intervention during the spraying process, reducing the time interrupted by manual flipping, and at the same time, it can keep the color steel plate in a stable position during the spraying process, thereby improving the overall spraying efficiency.

[0015] 2. By setting up a spraying mechanism, compared with the existing technology, the conical opening at the bottom of the spraying shell facilitates more concentrated spraying of the paint. At the same time, the two spraying shells can spray back and forth alternately, so that the metal powder paint can be more evenly covered on the surface of the color steel plate, reducing the problem of uneven coating thickness caused by fixed spraying angle or position.

[0023] 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.

[0024] The embodiments disclosed in this application are as follows: Figure 1-6The test spraying device for high-flexibility color steel plate powder coating shown includes a shell 1, a cabinet door 2 installed on the front side of the shell 1, a cylinder 3 fixedly connected to the top of the shell 1, a movable box 4 fixedly connected to the output end of the cylinder 3, a spraying mechanism installed inside the movable box 4, two infrared heating tubes 5 fixedly connected inside the shell 1, the two infrared heating tubes 5 are symmetrically distributed inside the shell 1, and a clamping assembly is installed inside the shell 1.

[0025] The clamping assembly includes a connecting box 6, which is fixedly connected to the interior of the outer casing 1. Two connecting rods 7 are fixedly connected to the front of the connecting box 6. Two sliding grooves 8 are formed on the front of the connecting rods 7, and sliding rods 9 are slidably connected to the inner sides of the sliding grooves 8. Two electric push rods 10 are installed inside the connecting box 6. A clamping plate 11 is fixedly connected to the output end of each electric push rod 10. A first rotating disk 12 is rotatably connected to one side of one clamping plate 11, and a first stepper motor 13 is fixedly connected to one side of the other clamping plate 11. A first gear 14 is fixedly connected to the output end of the first stepper motor 13. A second gear 15 meshes with one side of the first gear 14. A connecting shaft 16 is fixedly connected inside the second gear 15, and the connecting shaft 16 is rotatably connected to the interior of the other clamping plate 11. A second rotating disk 16 is fixedly connected to the outer side of the connecting shaft 16. Multiple anti-slip strips 18 are fixedly connected to one side of the first rotating plate 12 and the second rotating plate 17. Two electric push rods 10 pull the clamping plate 11 to move relative to each other. The sliding rod 9 slides and slides to the inside of the groove 8 to guide the movement. The two clamping plates 11 respectively drive the second rotating plate 17 and the first rotating plate 12 to clamp the color steel plate. The first gear 14 meshes with the second gear 15 to stably drive the second gear 15 to rotate. The second gear 15 drives the second rotating plate 17 to rotate through the connecting shaft 16. The clamping state of the second rotating plate 17 and the first rotating plate 12 can drive the color steel plate to rotate. This allows the color steel plate to be sprayed on both sides without manual intervention during the spraying process, reducing the time that the spraying operation is interrupted due to manual rotation.

[0026] Reference Figure 3 and 6As shown, the spraying mechanism includes a gear pump 19, with connecting pipes 20 at both the output and input ends of the gear pump 19. One end of one connecting pipe 20 is connected to a paint tank 21, which is fixedly connected to one side of the movable box 4. The other connecting pipe 20 is connected to a diverter pipe 22, which is fixedly connected to the inside of the movable box 4. The bottom end of the diverter pipe 22 is connected to two connecting hoses 23, one end of which is connected to a spraying pipe 24. The bottom end of the spraying pipe 24 is connected to multiple spray heads 25. Two second stepper motors 26 are fixedly connected to one side of the movable box 4. The output end of the second stepper motor 26 is fixedly connected to a lead screw 27, which is rotatably connected to the inside of the movable box 4. The outer side of the lead screw 27 is threadedly connected to a spraying housing 28, and the inner side of the spraying housing 28 is fixedly connected to the spraying pipe 24. By utilizing the different thread directions of the two lead screws 27, the two spraying housings 28 can move back and forth alternately. Through the conical opening at the bottom of the spraying housing 28, the paint can be discharged in a concentrated manner, so that the paint can be more evenly covered on the surface of the color steel plate, reducing the problem of uneven coating thickness caused by fixed spraying angle or position.

[0027] Working principle of this utility model: This utility model designs a testing and spraying device for high-flexibility color steel plate powder coating. The specific structure is shown in the attached instruction manual. Figure 1-6As shown, in this technical solution, through the cooperation of various structures, when the color steel plate needs to be sprayed, firstly, the cabinet door 2 is opened, and the color steel plate is placed between two clamping plates 11. Then, two electric push rods 10 are activated simultaneously, which pull the clamping plates 11 to move. At the same time, the sliding rod 9 is slidably connected to the inner side of the slide groove 8, so that the two clamping plates 11 can move relative to each other, thereby driving the second turntable 17 and the first rotating plate 12 to clamp the two sides of the color steel plate. Then, the cylinder 3 is activated, which pushes the movable box 4 downward, so that the two spraying shells 28 can move above the color steel plate. The gear pump 19 is started, which draws out the paint from the connecting pipe 20 and delivers it to the diversion pipe 22. The paint is then diverted through the diversion pipe 22 to two connecting hoses 23. The connecting hoses 23 deliver the paint to the spray pipe 24 so that multiple spray heads 25 can spray it. The tapered opening at the bottom of the spray housing 28 allows the paint to be sprayed out in a more concentrated manner. At the same time, the second stepper motor 26 is started, which drives the lead screw 27 to rotate. The opposite thread directions of the two lead screws 27 allow them to drive the spray housing 28 to reciprocate alternately. This allows for the spraying of the color steel plate surface. When the color steel plate needs to be flipped, the cylinder 3 raises the movable box 4, and then the first stepper motor 13 is started. The first stepper motor 13 drives the first gear 14 to rotate. The first gear 14 can mesh with and drive the second gear 15 to rotate, so that the second gear 15 can drive the second turntable 17 to rotate through the connecting shaft 16. The first flipping plate 12 is rotatably connected to one side of the clamping plate 11, and the color steel plate is clamped by the second turntable 17 and the first flipping plate 12. Thus, when the second turntable 17 rotates, it can drive the first flipping plate 12 to rotate, so as to complete the flipping of the color steel plate.
