Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel furniture processing technology, and in particular to an anti-splash atomization device for spraying coatings on the surface of steel furniture. Background Technology
[0002] In the production and processing of steel furniture, in order to improve the appearance quality, rust resistance and service life of the furniture, it is usually necessary to spray the surface of the steel furniture. At present, the commonly used device for spraying the surface of steel furniture is the hand-held spray gun, which is widely used in the spraying operation of small steel furniture.
[0003] However, when using existing handheld spray guns to spray the edges and corners of steel furniture, some material may be sprayed onto adjacent surfaces, contaminating them. Furthermore, when spraying adjacent surfaces, the coating may overlap at the edges, resulting in an excessively thick coating, which has limitations.
[0004] The reason for this problem is that in actual spraying operations, the atomized paint sprayed from the nozzle spreads in a fan shape. When the nozzle sprays to the edge of the plane, the material sprayed from the nozzle will cross the corner and spray onto the adjacent material surface, causing excess material to splash onto the adjacent material surface and causing pollution. Furthermore, when spraying adjacent material surfaces, the corners will be sprayed a second time, resulting in the corners being sprayed too thickly, which has limitations. Utility Model Content
[0005] The purpose of this invention is to provide a splash-proof atomizing device for spraying coatings on the surface of steel furniture, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: A splash-proof atomizing device for spraying coating on the surface of steel furniture, comprising a nozzle body, wherein a folding isolation unit is provided on one side of the nozzle body, and the folding isolation unit comprises a folding strip, a positioning block and a locking component;
[0007] The positioning block is fixedly assembled on one side of the nozzle body, the end of the folding strip is rotatably connected to the inside of the positioning block, and the locking member is disposed inside the positioning block. The locking member is used to fix the folding strip after it is rotated 90°.
[0008] Preferably, the positioning block includes a left positioning block and a right positioning block;
[0009] The left and right fixed blocks are respectively disposed on both sides of the folding strip, and the left and right fixed blocks are fixedly assembled with the nozzle body.
[0010] Preferably, a rotating shaft is fixedly mounted inside the folding strip, and the rotating shaft is rotatably connected to the positioning block.
[0011] Preferably, the nozzle body has a feed inlet at one end, and a spray gun is provided on one side of the nozzle body, with the nozzle body and the spray gun being threaded together.
[0012] Preferably, the locking element includes a slot and a spring;
[0013] The slot is located inside the right fixed block; one end of the spring is fixedly assembled inside the slot.
[0014] Preferably, the locking element further includes a plug and a slot;
[0015] The insert is slidably connected inside the slot, and the insert is equilateral triangle in shape. The slot is opened inside the rotating shaft, and the insert is movably engaged in the slot and the slot respectively, thereby preventing the rotating shaft from rotating.
[0016] Preferably, the locking element further includes a push rod;
[0017] The push rod is fixedly assembled at the end of the insert block, and the push rod is slidably connected inside the positioning block.
[0018] The technical effects and advantages of this utility model are as follows:
[0019] This device, through its folding isolation unit, allows the folding strip to rotate 90° and be fixed by locking components when spraying the edges and corners of steel furniture. The folding strip abuts against the adjacent surface, limiting the spray range of the nozzle and preventing atomized paint from splashing across the edges and corners onto the adjacent surfaces. This solves the problem of contaminating adjacent surfaces when spraying edges and corners with existing handheld spray guns. Furthermore, it prevents secondary spraying of edges and corners, solving the problem of excessively thick coating at edges and corners and improving the spraying quality of steel furniture.

[0026] 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.
[0027] This utility model provides, for example Figures 1 to 4 The device shown is a splash-proof atomizing device for spraying on the surface of steel furniture. It includes a nozzle body 1, and a folding isolation unit 2 is provided on one side of the nozzle body 1. The folding isolation unit 2 includes a folding strip 21, a positioning block 22 and a locking element 23.
[0028] The positioning block 22 is fixedly assembled on one side of the nozzle body 1. The end of the folding strip 21 is rotatably connected to the inside of the positioning block 22. The locking member 23 is disposed inside the positioning block 22. The locking member 23 is used to fix the folding strip 21 after it is rotated 90°.
[0029] The positioning block 22 includes a left positioning block 221 and a right positioning block 222; the left and right positioning blocks 221 and 222 are respectively disposed on both sides of the folding strip 21, and are fixedly assembled with the nozzle body 1. A rotating shaft 24 is fixedly assembled inside the folding strip 21, and the rotating shaft 24 is rotatably connected to the positioning block 22. A feed port 3 is opened at the end of the nozzle body 1, and a spray gun is provided on one side of the nozzle body 1, with the nozzle body 1 and the spray gun threadedly engaged. The locking component 23 includes a slot 231 and a spring 232; the slot 231 is opened inside the right positioning block 222; one end of the spring 232 is fixedly assembled inside the slot 231. The locking component 23 also includes an insert block 233 and a slot 234; the insert block 233 is slidably connected inside the slot 231, and the insert block 233 is equilateral triangular in shape; the slot 234 is opened inside the rotating shaft 24, and the insert block 233 is movably engaged inside the slot 234 and the slot 231 respectively, thereby preventing the rotating shaft 24 from rotating. The locking component 23 also includes a push rod 235; the push rod 235 is fixedly assembled at the end of the insert block 233, and the push rod 235 is slidably connected inside the positioning block 22.
[0030] Example 1: In this example, the operator holds a spray gun, aligns the nozzle of the spray head 1 with the surface of the steel furniture, and feeds paint through the inlet 3. By controlling the spray gun switch, the operator can perform surface spraying. When the paint reaches the corner of the steel furniture surface, the operator presses the push rod 235 inward. The push rod 235 pushes the insert 233 out of the slot 234. At this time, the spring 232 is compressed. The operator then pushes the folding strip 21, causing it to rotate around the shaft 24. During rotation, the shaft 24 drives the slot 234 to rotate as well. When the folding strip 21 rotates 90°, the slot 234 aligns with the groove 231 in the right fixed block 222. The operator then releases the push rod 235. Under the elastic force of the spring 232, the insert 233 slides out of the groove 231 and engages in the slot 234, thus stopping the shaft 24. Turn the folding bar 21 so that its bent head is against the adjacent surface. At this time, the operator holds the spray gun and aims the nozzle of the spray head 1 at the surface of the steel furniture. The spray gun is turned on, and the paint is atomized and sprayed out from the nozzle of the spray head 1. Under the obstruction of the folding bar 21, the atomized paint cannot cross the corners and splash onto the adjacent surface, thus avoiding contamination of the adjacent surface. The same steps are followed when spraying adjacent surfaces. After the entire surface is sprayed, the operator pushes the push rod 235 by hand. The push rod 235 drives the insert block 233 to slide in the slot 231 against the elastic force of the spring 232, so that the insert block 233 exits from the slot 234 and returns to the slot 231, releasing the anti-rotation of the rotating shaft 24. Then, the folding bar 21 is rotated to the initial position. At this time, the spray gun can be tilted so that it can be sprayed directly on the corners to ensure that there is no coating overlap at the corners, thus meeting the user's needs.
[0031] like Figure 5 The device shown is a splash-proof atomizing device for spraying on the surface of steel furniture. It includes a nozzle body 1, and a folding isolation unit 2 is provided on one side of the nozzle body 1. The folding isolation unit 2 includes a folding strip 21, a positioning block 22 and a locking element 23.
[0032] The positioning block 22 is fixedly assembled on one side of the nozzle body 1. The end of the folding strip 21 is rotatably connected to the inside of the positioning block 22. The locking member 23 is disposed inside the positioning block 22. The locking member 23 is used to fix the folding strip 21 after it is rotated 90°.
[0033] Example 2: In this example, the threaded end of the nozzle body 1 is connected to the spray gun via a threaded connection to complete the assembly of the entire device, ensuring that all components of the device are firmly connected and can perform normal spraying operations. The spray gun used here is a pneumatic handheld spray gun, which has an airflow channel and a paint channel inside. The airflow channel is connected to an external compressed air source, and the paint channel is connected to an external material storage device through the feed port 3, providing a basis for subsequent paint delivery and atomization.
