Description

Technical Field

[0001] This utility model relates to the field of coating nozzle technology, specifically a coating nozzle for an automotive coating production line. Background Technology

[0002] In today's automotive manufacturing industry, automotive painting, as a crucial link in the automobile production process, plays a decisive role in the appearance quality, durability, and market competitiveness of vehicles. With the rapid development of the automotive industry and the continuous improvement of consumers' demands for vehicle quality, automotive painting processes face increasingly stringent challenges. However, in the existing technology, the fixed flow rate feeding system cannot be flexibly adjusted according to different coating processes and paint characteristics. For example, when applying primer, topcoat, and special effects coating, the required paint flow rate and spraying speed are different. The fixed flow rate feeding system is difficult to meet these diverse needs, resulting in inconsistent coating quality and problems such as uneven coating thickness, sagging, and missed coating, which affect the appearance quality and overall performance of the car. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a coating nozzle for an automotive coating production line, which solves the problem of the inability to adjust the paint flow rate.

[0012] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0013] Please see Figure 1-8 This utility model provides a technical solution: a coating nozzle for an automotive coating production line, comprising: a main frame 1, an adjusting device 2 snapped onto the outer wall of the main frame 1, a connecting device 3 snapped onto the outer wall of the adjusting device 2, a discharge device 4 threaded onto the outer wall of the main frame 1, the adjusting device 2 comprising an adjusting outer frame 21, an adjusting plate 22 slidably connected to the outer wall of the adjusting outer frame 21, a limiting ball 23 slidably connected to the inner wall of the adjusting outer frame 21, a compression spring 24 fixedly connected to the inner wall of the adjusting outer frame 21, the outer wall of the compression spring 24 slidably connected to the outer wall of the limiting ball 23, and a retaining ring 25 fixedly connected to the outer wall of the adjusting outer frame 21, wherein the limiting ball 23 can be automatically reset by the compression spring 24.

[0014] Five sets of adjustment plates 22 are provided. Each adjustment plate 22 includes an adjustment baffle 221. A fixed rotating shaft 222 is fixedly connected to the outer wall of the adjustment baffle 221. A sliding rotating shaft 223 is fixedly connected to the outer wall of the adjustment baffle 221. The outer wall of the fixed rotating shaft 222 is rotatably connected to a hole in the outer wall of the main frame 1. The outer wall of the sliding rotating shaft 223 is slidably connected to a groove in the outer wall of the adjustment outer frame 21. The outer wall of the adjustment outer frame 21 is engaged with the outer wall of the main frame 1 by a retaining ring 25. The outer wall of the retaining ring 25 is engaged with a groove in the outer wall of the main frame 1. The adjustment plate 22 can slide in the groove on the adjustment outer frame 21 by the sliding rotating shaft 223.

[0015] The connecting device 3 includes a connecting pipe 31, a limiting pipe 32 is fixedly connected to the outer wall of the connecting pipe 31, the outer wall of the limiting pipe 32 is engaged with the outer wall of the adjusting outer frame 21, and the groove on the outer wall of the limiting pipe 32 is engaged with the outer wall of the limiting ball 23. The limiting ball 23 can be fixed in position on the connecting pipe 31 through the groove on the connecting pipe 31.

[0016] The discharge device 4 includes a nozzle 41, a fixed bracket 42 is fixedly connected to the outer wall of the nozzle 41, a fixed knob 43 is threadedly connected to the inner wall of the fixed bracket 42, a baffle block 44 is fixedly connected to the outer wall of the fixed knob 43, the outer wall of the nozzle 41 is threadedly connected to the outer wall of the main frame 1, and the position of the baffle block 44 can be adjusted by the fixed knob 43.

[0017] When in use, the first step is to connect the feed pipe through the connecting device 3. When connecting the feed pipe, the limiting tube 32 is used to connect with the feed pipe, which prepares the paint to enter the nozzle 41.

[0018] The feeding speed is controlled by the adjusting device 2. When the feeding speed needs to be adjusted, the adjusting outer frame 21 is rotated. Since the fixed rotating shaft 222 on the adjusting plate 22 is rotatably connected to the hole on the main frame 1, the sliding rotating shaft 223 will slide relative to the main frame 1 in the groove on the adjusting outer frame 21 during the rotation of the adjusting outer frame 21, thereby driving the adjusting baffle 221 to rotate. When the adjusting baffle 221 rotates, it will open or close, thereby changing the size of the feeding channel, so as to realize the adjustment of the feeding speed. After the rotation is completed, the limiting ball 23 will be locked into the groove on the connecting pipe 31 under the action of the compression spring 24, thus fixing the position of the adjusting device 2.

[0019] In the actual coating process, it is sometimes necessary to adjust the spraying range. At this time, it is necessary to operate the discharge device 4. When it is necessary to adjust the spraying range, turn the fixed knob 43 on the discharge device 4. When the fixed knob 43 is turned, it will drive the baffle block 44 to move towards the nozzle 41. The movement of the baffle block 44 will change the angle of paint spraying, thereby achieving the adjustment of the spraying angle and thus achieving the purpose of adjusting the spraying range.
