Description

Technical Field

[0001] This utility model relates to the field of enamel coating technology, and in particular to a spray head for an enamel coating machine. Background Technology

[0002] Enamel coating technology plays a vital role in industrial manufacturing, particularly in the home appliance, building materials, and medical device industries. Enamel coatings are widely used due to their corrosion resistance, wear resistance, and aesthetic appeal. As a key piece of equipment in realizing this technology, the performance of the enamel coating machine directly affects the uniformity, efficiency, and quality of the coating, thus having a decisive impact on the final product quality.

[0003] Existing enamel coating technology has several limitations in practical applications. First, many coating machines have fixed nozzle designs, making it impossible to adjust the spraying range according to the specific shape and size of the object. This can lead to uneven spraying, affecting the quality and appearance of the enamel coating. Second, when different types of nozzles need to be changed to meet varying coating requirements, existing equipment often lacks convenient replacement mechanisms, resulting in time-consuming and labor-intensive processes. Furthermore, after prolonged operation, some coating machines struggle to maintain uniformity and consistency in spraying due to the fixed and non-adjustable nozzles, thus reducing production efficiency and product quality. Therefore, the technical problems that need to be solved include how to achieve flexible adjustment of the nozzle spraying range and how to simplify the nozzle replacement process to improve coating efficiency and quality while reducing production costs.

[0004] In response to this technical problem, this application proposes a spray head for an enamel spraying machine. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a nozzle for an enamel coating machine. This nozzle allows for adjustment of the spraying range, preventing uneven coating of the object surface caused by a fixed spraying position, improving the quality of enamel coating, ensuring uniform material distribution, and facilitating convenient replacement of the nozzle. It also avoids the limitations of one-piece, non-removable nozzles that prevent the replacement of different types of nozzles, thus improving work efficiency and shortening the installation and disassembly time of the nozzle.

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

[0007] A nozzle for an enamel coating machine includes a fixed frame. A storage tank is fixedly connected to the top side of the fixed frame, and a feeding port is fixedly connected to the middle of the top side of the storage tank. A fixed base is fixedly connected to the top side of the fixed frame, and a fixed sleeve is fixedly connected inside the fixed base. An adjustment component is provided inside the fixed sleeve. Three mounting brackets are rotatably connected to the outer wall of the fixed base. A sliding plate is slidably connected inside each of the three mounting brackets. A nozzle is provided at the bottom of each of the three sliding plates. A quick-release component is provided on the outer wall of each of the three nozzles. A connecting plate is provided on the side of each of the three sliding plates that is close to the fixed sleeve.

[0008] Furthermore, the adjusting assembly includes a threaded rod rotatably connected to the inside of the fixed sleeve, a movable sleeve being threadedly connected to the outer wall of the threaded rod, and a limit plate being fixedly connected to the bottom end of the threaded rod.

[0009] Furthermore, the quick-release assembly includes sliders that are slidably connected to both the left and right ends of the outer wall of the nozzle. The two sliders are fixedly connected to pins at both ends on the opposite side. Limit blocks are provided on the adjacent side of the two sliders. Springs are provided on the adjacent side of the two limit blocks.

[0010] Furthermore, three connecting pipes are fixedly connected to the outer wall of the storage tank, and the bottom ends of the three connecting pipes are all connected to the nozzle.

[0011] Furthermore, the movable sleeve is fixedly connected to a fixing block on the side adjacent to the three sliding plates, and a rotating shaft is fixedly connected inside the fixing block. The left and right ends of the connecting plate are rotatably connected to the outer wall of the rotating shaft.

[0012] Furthermore, a motor is provided on the top side of the fixed sleeve, and the drive end of the motor is connected to the top end of the threaded rod.

[0013] Furthermore, one end of the spring is connected to the interior of the nozzle, and the other end is connected to one side of the two limiting blocks.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by adjusting the size of the nozzle connection mechanism of the enamel spraying machine, the spraying range of the nozzle can be adjusted, avoiding uneven spraying of the object surface due to the fixed spraying position of the nozzle, improving the enamel spraying quality, and ensuring uniform material reception on the object.

[0016] 2. In this utility model, by setting a fixing mechanism at the nozzle connection, the nozzle of the enamel spraying machine can be conveniently replaced, avoiding the inability to replace different types of nozzles due to the one-piece non-removable nozzle, thus improving work efficiency and shortening the nozzle installation and disassembly time.

[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] Reference Figure 1This utility model provides an embodiment of an enamel coating machine nozzle, comprising a fixed frame 1, a storage tank 2 fixedly connected to the top side of the fixed frame 1, a feeding port 3 fixedly connected to the middle of the top side of the storage tank 2, a fixed base 5 fixedly connected to the top side of the fixed frame 1, a fixed sleeve 8 fixedly connected inside the fixed base 5, a movable sleeve 14 disposed inside the fixed sleeve 8, three mounting brackets 10 rotatably connected to the outer wall of the fixed base 5, each of the three mounting brackets 10 having a sliding plate 12 slidably connected inside, a nozzle 6 disposed at the bottom of each of the three sliding plates 12, a slider 18 disposed on the outer wall of each of the three nozzles 6, and a connecting plate 7 disposed on the side of each of the three sliding plates 12 near the fixed sleeve 8. First, the enamel coating is injected. Specifically, the enamel coating is slowly injected into the storage tank 2 through the feeding port 3 on the top side of the storage tank 2. Then, the coating flows along the connecting pipe 4 and enters the nozzle 6, preparing for the subsequent coating spraying. Three connecting pipes 4 are fixedly connected to the outer wall of the storage tank 2. The bottom ends of the three connecting pipes 4 are all connected to the nozzle 6 to ensure normal paint transportation. Fixed blocks 15 are fixedly connected to the side of the movable sleeve 14 closest to the three sliding plates 12. A rotating shaft 13 is fixedly connected inside the fixed block 15. The left and right ends of the connecting plate 7 are rotatably connected to the outer wall of the rotating shaft 13. Under the action of the connecting plate 7 and the rotating shaft 13, the three sliding plates 12 can be rotated and adjusted horizontally. This adjustment method is similar to the storage method of an umbrella frame. By changing the distance between the three sliding plates 12 and the threaded rod 11, the spraying range of the nozzle 6 can be effectively adjusted. In this way, spraying operations can be performed from multiple angles for objects of different sizes, thereby avoiding uneven material distribution during spraying and ensuring that the enamel paint on the surface of the object is evenly covered. A motor 9 is installed on the top side of the fixed sleeve 8. The drive end of the motor 9 is connected to the top of the threaded rod 11 to increase structural stability. One end of the spring 16 is connected to the inside of the nozzle 6, and the other end is connected to the adjacent side of the two limiting blocks 17 to increase structural stability.

[0024] Reference Figure 2 A threaded rod 11 is rotatably connected inside the fixed sleeve 8. A movable sleeve 14 is threadedly connected to the outer wall of the threaded rod 11. A limit plate is fixedly connected to the bottom end of the threaded rod 11. When it is necessary to adjust the paint spraying range, the motor 9 needs to be started. After the motor 9 starts running, it will drive the threaded rod 11 to rotate inside the fixed sleeve 8. The movable sleeve 14 is provided on the outer wall of the threaded rod 11. Since they are threadedly connected, during the rotation of the threaded rod 11, the movable sleeve 14 will move vertically along the outer wall of the threaded rod 11 under the action of the threads.

[0025] Reference Figure 3The nozzle 6 has sliders 18 slidably connected to both ends of its outer wall. Pins 19 are fixedly connected to the front and rear ends of the two sliders 18 on opposite sides. Limiting blocks 17 are provided on the adjacent sides of the two sliders 18, and springs 16 are provided on the adjacent sides of the two limiting blocks 17. When the two sliders 18 on the outer wall of the nozzle 6 are pressed and move towards each other towards the center of the nozzle 6, they exert a squeezing force on the two limiting blocks 17. Under this squeezing, the limiting blocks 17 are pushed out of their original engaged position inside the nozzle 6. Since the bottom of the nozzle 6 has molds of different orifice sizes, these molds can also disengage from the interior of the nozzle 6 as the limiting blocks 17 are pushed out of their engaged position, thus facilitating the replacement of the nozzle 6.

[0026] Working principle: First, enamel paint is injected into the storage tank 2 through the feeding port 3 on the top side of the storage tank 2. The paint then enters the nozzle 6 through the connecting pipe 4 for spraying. When it is necessary to adjust the paint spraying range, the motor 9 is started. The motor 9 drives the threaded rod 11 to rotate inside the fixed sleeve 8. The movable sleeve 14 on the outer wall of the threaded rod 11 can move vertically on the outer wall of the threaded rod 11 under the action of the threaded connection. With the cooperation of the connecting plate 7 and the rotating shaft 13, the three sliding plates 12 can rotate and adjust horizontally, similar to the storage of umbrella ribs. The spraying range of the nozzle 6 can be adjusted by adjusting the distance between the three sliding plates 12 and the threaded rod 11, allowing for multi-angle spraying of objects of different specifications and avoiding uneven material distribution. When the nozzle 6 needs to be replaced according to different object types, the two sliders 18 on the outer wall of the nozzle 6 can be pressed. When the two sliders 18 move towards the nozzle 6, they can squeeze the two limiting blocks 17, pushing the limiting blocks 17 out of their engaging position inside the nozzle 6. This allows the molds with different aperture sizes at the bottom of the nozzle 6 to disengage from the inside of the nozzle 6, thus enabling the replacement of the nozzle 6.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
