Description

Technical Field

[0001] This utility model relates to the field of spray painting equipment, and in particular to a spray painting device for the surface of food iron cans. Background Technology

[0002] Food tin cans are containers used for packaging food, made primarily of metal materials such as tinplate, and manufactured through a series of processing techniques. After the food tin cans are formed, a painting device is needed to spray paint the surface of the cans to achieve functions such as protection and decoration. Typically, the food tin cans are placed on a rotating worktable. After the equipment is started, the worktable drives the tin cans to rotate at a uniform speed, while the spray gun sprays paint onto the surface of the tin cans. Due to the rotation of the tin cans, the paint can be evenly covered on the circumference of the tin cans.

[0003] Most existing painting equipment uses fixed spray guns, which may result in inconsistent paint coverage on different parts of the tin can surface. For example, if the spray gun is too close to certain parts of the tin can, too much paint will be sprayed in that area, which may cause drips, accumulation, and other problems. On the other hand, if the spray gun is farther away, the amount of paint sprayed may be insufficient, resulting in uneven surface color, exposed substrate, and other problems, which seriously affect the appearance quality and protective performance of food tin cans.

[0004] Therefore, since most of the existing painting devices use fixed spray guns, which may lead to uneven painting on the surface of the iron can, resulting in uneven surface color and exposed substrate, seriously affecting the appearance quality and protective performance of the food iron can, a food iron can surface painting device can be designed, which adopts an adjustable support structure to expand the spraying area of ​​the spray gun. Utility Model Content

[0005] To overcome the problem that most existing painting equipment uses fixed spray guns, which may lead to uneven painting on the surface of iron cans, resulting in uneven surface color and exposed substrate, seriously affecting the appearance quality and protective performance of food iron cans.

The support assembly includes a rectangular slide rail, a rectangular groove is provided on the inner side of the rectangular slide rail, a threaded rod is vertically inserted through the inner side of the rectangular groove of the rectangular slide rail, a rectangular threaded sleeve is sleeved on the outside of the threaded rod, a first U-shaped frame is installed on one side of the rectangular threaded sleeve, a first rotating shaft is horizontally inserted through the middle of the first U-shaped frame, a guide post is provided on the side of the first U-shaped frame away from the rectangular threaded sleeve, the guide post is rotatably connected to the first U-shaped frame through the first rotating shaft, a second U-shaped frame is provided on the end of the guide post away from the first U-shaped frame, a second rotating shaft is horizontally inserted through the end of the guide post away from the first U-shaped frame, and the second U-shaped frame is rotatably connected to the guide post through the second rotating shaft.

[0007] Preferably, the iron can is placed on the operating platform above the support platform, and then the operating platform is rotated while the liquid supply tank is activated to spray out the paint. During this process, the support components are raised, lowered, rotated and adjusted to adjust the spraying direction, so that the paint on the surface of the iron can is more even.

[0008] As a preferred embodiment, each of the lower corners of the load-bearing platform is equipped with a column, and a base plate is provided below the load-bearing platform that is fixedly connected to the column. An annular groove is provided in the middle of the upper part of the load-bearing platform.

[0009] Preferably, an operating platform is provided above the load-bearing platform, a rotating column is installed in the middle of the lower end of the operating platform, a drive motor is installed at the lower end of the rotating column, and multiple sets of support columns are installed around the lower edge of the operating platform. The support columns drive the operating platform to slide along the annular groove and connect with the load-bearing platform.

[0010] Preferably, a water pump is installed at one corner of the liquid supply tank, and a water inlet pipe is installed at the upper corner of the liquid supply tank.

[0011] Preferably, water outlet pipes are symmetrically installed on both sides of the liquid supply tank, and a nozzle is installed at the end of the water outlet pipe away from the liquid supply tank. A fixing ring is fitted around the outside of the water outlet pipe.

[0012] Preferably, a rotating motor is installed at the upper end of the threaded rod, and a first motor is installed at one end of the first rotating shaft.

[0013] Preferably, a second motor is installed at one end of the second rotating shaft, and the fixing ring is fixedly connected to the second U-shaped frame.

[0014] The beneficial effects of this utility model are as follows: The tin can is placed on the operating platform above the support platform. The operating platform then rotates, simultaneously activating the paint supply tank to spray paint. During this process, the support components are raised, lowered, and rotated to adjust the spray direction, resulting in more uniform paint coverage on the tin can surface. This allows for flexible angle adjustment, ensuring even paint coverage and preventing issues such as excessively thick or thin areas, or missed areas. This guarantees consistent and complete paint application, improving appearance quality. Furthermore, since food tin cans may vary in size and shape during production, the adjustable spray gun direction eliminates the need for frequent equipment changes or complex adjustments, quickly adapting to the painting needs of various tin cans, reducing equipment setup time, and increasing production efficiency.

A second U-shaped frame 310 is provided at the end of the guide post 309 away from the first U-shaped frame 306. A second rotating shaft 311 is transversely inserted at the end of the guide post 309 away from the first U-shaped frame 306. The second U-shaped frame 310 is rotatably connected to the guide post 309 through the second rotating shaft 311.

[0022] Please see Figure 2In this embodiment, each of the lower corners of the support platform 1 is equipped with a column 101. The support platform 1 is provided with a base plate 102 fixedly connected to the column 101. An annular groove 103 is provided in the middle of the upper part of the support platform 1. Driven by the drive motor 106, the rotating column 105 drives the operating table 104 to rotate at a constant speed. The operating table 104 is provided above the support platform 1. The rotating column 105 is installed in the middle of the lower part of the operating table 104. The drive motor 106 is installed at the lower end of the rotating column 105. Multiple sets of support columns 107 are installed around the lower edge of the operating table 104. The support columns 107 drive the operating table 104 to slide along the annular groove 103 and slide to connect with the support platform 1. The support columns 107 drive the operating table 104 to slide along the annular groove 103 and slide to connect with the support platform 1, thereby providing auxiliary support for the operating table 104.

[0023] Please see Figure 3 In this embodiment, a water pump 201 is installed at one corner of the liquid supply tank 2, and a water inlet pipe 202 is installed at the upper corner of the liquid supply tank 2. The paint liquid is poured into the liquid supply tank 2 through the water inlet pipe 202. Water outlet pipes 203 are symmetrically installed on both sides of the liquid supply tank 2. A nozzle 204 is installed at the end of the water outlet pipe 203 away from the liquid supply tank 2. A fixing ring 205 is fitted on the outside of the water outlet pipe 203. Driven by the water pump 201, the paint liquid enters the water outlet pipe 203 from the liquid supply tank 2 and is sprayed through the nozzle 204.

[0024] Please see Figure 4 In this embodiment, a rotating motor 304 is installed on the upper end of the threaded rod 303, and a first motor 308 is installed on one end of the first rotating shaft 307. Driven by the first motor 308, the guide post 309 rotates to a suitable angle through the first rotating shaft 307 and the first U-shaped frame 306. A second motor 312 is installed on one end of the second rotating shaft 311. The fixing ring 205 is fixedly connected to the second U-shaped frame 310. Driven by the second motor 312, the second U-shaped frame 310 drives the fixing ring 205 to rotate to a suitable angle through the second rotating shaft 311 and the guide post 309.

[0025] When working, first place the iron can on the operating table 104, then pour the paint into the supply tank 2 through the water inlet pipe 202, and then drive the rotating column 105 to drive the operating table 104 to rotate at a constant speed through the drive motor 106. At the same time, the support column 107 drives the operating table 104 to slide along the annular slide groove 103 and slide to connect with the load-bearing platform 1, thereby providing auxiliary support for the operating table 104. Finally, driven by the water pump 201, the paint enters the water outlet pipe 203 from the supply tank 2 and is sprayed through the nozzle 204.

[0026] During the spraying process, depending on the height of the can, the threaded rod 303 rotates under the drive of the rotating motor 304, causing the rectangular threaded sleeve 305 to move the first U-shaped frame 306 along the rectangular slide groove 302 inside the rectangular slide rail 301 to a suitable height. Then, depending on the width of the can, the guide post 309 rotates to a suitable angle via the first rotating shaft 307 and the first U-shaped frame 306 under the drive of the first motor 308. At the same time, the second U-shaped frame 310 rotates to a suitable angle via the second rotating shaft 311 and the guide post 309 under the drive of the second motor 312. Through continuous rotation and adjustment, the spray head 204 is adjusted to a suitable position at a distance from the can, so that the coating can be evenly covered on the surface of the can.

[0027] Through the above steps, the tin can is placed on the operating platform 104 above the support platform 1. Then, the operating platform 104 rotates, and at the same time, the liquid supply tank 2 is activated to spray out the paint. During this process, the support components are raised, lowered, rotated, and adjusted to adjust the spraying direction, making the paint spraying on the surface of the tin can more uniform. This allows for flexible adjustment of the angle, ensuring that the paint evenly covers the surface of the tin can, avoiding problems such as excessively thick or thin areas, or missed areas. This ensures the consistency and integrity of the paint spraying, improves the appearance quality, and, since the specifications and shapes of food tin cans may vary during production, the adjustable spray gun direction paint spraying device can quickly adapt to the painting needs of various tin cans without frequent equipment changes or complex adjustments. This reduces equipment debugging time, improves production efficiency, and solves the problem that most existing paint spraying devices use fixed spray guns, which may lead to uneven paint spraying on the surface of the tin can, resulting in uneven surface color, exposed substrate, and other problems that seriously affect the appearance quality and protective performance of food tin cans.
