Due to the advantages of high work efficiency and good spraying effect, the automatic spraying line is widely used in spraying processing plants.

[0003] In the existing technology, by pressing the spring tongue, hydraulic pressure is generated inside, so that the paint is adsorbed into the interior of the spray gun and finally discharged from the nozzle. This operation is convenient and quick, but the existing nozzle is connected to the nozzle by a bolt. When it needs to be replaced, the bolts need to be loosened with the help of auxiliary tools, which is troublesome to operate. In addition, some workpiece surfaces need to be sprayed with more than one color of paint. When the color of the spray paint needs to be changed, the only way is to manually remove the connected paint box, replace the paint of another color and pour it into the interior of the paint box, and then manually dock and fix it with the spray gun. This operation is not only cumbersome but also time-consuming.

DETAILED DESCRIPTION

[0026] The following will combine the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] Example:

[0028] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0029] A spray gun structure for an automatic spray painting line includes a handle 1, a spring tongue 2 being slidably connected to the bottom of the handle 1, an extension shaft 3 being fixedly connected to the left end of the handle 1, a connecting sleeve 4 being threadedly connected to the bottom of the handle 1 and located outside the spring tongue 2, a cover 5 being fixedly connected to the bottom of the connecting sleeve 4, a paint cartridge 6 being pluggably connected to the bottom of the cover 5, a sleeve 7 being fixedly connected to the outside of the extension shaft 3, a nozzle 8 being pluggably connected to the left end of the sleeve 7, and a quick-release assembly 9 being installed inside the sleeve 7;

[0030] The quick-release assembly 9 is used for quickly disassembling and assembling the nozzle 8, making it convenient to replace the nozzle 8 with a new one.

[0031] For further information, see Figure 1 、 Figure 2 and Figure 3 In this embodiment, the quick-release assembly 9 includes an extension tube 901, a main shaft 902, a spring 903, a fixed plate 904, a receiving groove 905 and a first ball 906. The extension tube 901 is fixedly connected to the left end of the sleeve 7, the main shaft 902 is slidably connected to the inside of the sleeve 7, the spring 903 is sleeved on the outside of the main shaft 902, the fixed plate 904 is fixedly connected to the top of the main shaft 902, the receiving groove 905 is opened in the inside of the fixed plate 904, and the first ball 906 is rollingly connected to the outside of the extension tube 901 and the fixed plate 904. By pressing the spring tongue 2, hydraulic pressure is generated inside, thereby moving the paint box 6 inside. Part of the pigment is absorbed into the interior of the extension shaft 3, and finally transmitted from the air pipe to the outside of the nozzle 8 to complete the spraying work. When a small-caliber nozzle 8 is needed, the main shaft 902 is moved away from the nozzle 8, so that the spring 903 is compressed and moves synchronously with the main shaft 902. Then the fixed plate 904 moves with the main shaft 902, so that the nozzle 8 is separated from the interior of the receiving groove 905. Due to the inclined design of the extension tube 901, in order to cooperate with the movement of the main shaft 902, the top of the fixed plate 904 also presents an inclined design, so that the first ball 906 falls to the inclined surface of the fixed plate 904 and the extension tube 901.

[0032] For further information, see Figure 1 、 Figure 2 and Figure 3 In this embodiment, the bottom end of the inner side of the sleeve 7 is fixedly connected with a blocking disk 10, and the nozzle 8 is plugged and unplugged with the fixed disk 904 through the accommodating groove 905. The bottom end of the nozzle 8 is designed with an arc structure. The blocking disk 10 blocks the spring 903 when it moves to the right, completing the compression of the spring 903, and the first ball 906 leaves the bottom of the nozzle 8, releasing the squeezing of the nozzle 8, and the nozzle 8 is easily removed.

[0033] For further information, see Figure 2 and Figure 3 In this embodiment, the bottom of the main shaft 902 is fixedly connected to the support shaft 907, and the bottom of the support shaft 907 is fixedly connected to the impact shaft 908. The top of the impact shaft 908 is designed with an inward contraction structure. The bottom of the impact shaft 908 is fixedly connected to the airbag 909, and the bottom end of the inner side of the sleeve 7 and the outside of the impact shaft 908 are slidably connected with a sleeve 910. The top of the inner side of the sleeve 910 is fixedly connected with an extrusion piece 911, and a second ball 912 is rollingly connected between the blocking disk 10 and the extrusion piece 911. By sliding the sleeve 910 to the left end, the airbag 909 is restored to its original position, and then the extrusion piece 911 squeezes the second ball 912 between the extrusion piece 911 and the blocking disk 10, so that the main shaft 902 is restored to its original position, and the first ball 906 is stuck in both sides of the nozzle 8, completing the installation of the new nozzle 8.

[0034] For further information, see Figure 2 and Figure 3 In this embodiment, a circular groove 913 is symmetrically opened inside the impact shaft 908, and the circular groove 913 is designed in a trumpet-shaped structure. A third ball 914 is connected to the inside of the circular groove 913 in a rolling manner. When the main shaft 902 returns to its original position, the third ball 914 contacts the extrusion sheet 911, completing the limitation of the main shaft 902 and preventing the main shaft 902 from escaping from the inside of the sleeve 7.

[0035] For further information, see Figure 1 and Figure 4 In this embodiment, the interior of the paint box 6 is fixedly connected to a sub-packaging box 11, and the interior of the sub-packaging box 11 is fixedly connected to a connecting tube 12, which extends to the interior of the extension shaft 3. By opening the lid 5 to expose the sub-packaging box 11, two different paints are filled into the interior of the sub-packaging box 11, and the connecting tubes 12 are respectively inserted into the interior of the sub-packaging box 11, and the internal paint is transferred to the interior of the extension shaft 3 through a pump.

[0036] For further information, see Figure 1 、 Figure 4 and Figure 5In this embodiment, the paint box 6 has a horizontal axis 13 for external rotation, and a turntable 14 is fixedly connected to the outside of the horizontal axis 13 and located inside the paint box 6. The turntable 14 is rotatably connected to a connecting rod on the outside, and the end of the connecting rod away from the turntable 14 is slidably connected to a track 15. The back of the track 15 is fixedly connected to a tooth plate 16, and the outside of the tooth plate 16 is slidably connected to a slide rail 17. By rotating the horizontal axis 13, the turntable 14 drives the connecting rod to rotate, so that the track 15 follows the movement of the connecting rod and makes a left and right translation motion, so that the tooth plate 16 slides back and forth inside the slide rail 17.

[0037] For further information, see Figure 1 、 Figure 4 and Figure 5 In this embodiment, a rectangular box 18 is fixedly connected to the top of the slide rail 17, and an insert shaft 19 is rotatably connected to the inside of the rectangular box 18. A gear 20 is fixedly connected to the left end of the insert shaft 19 at a position corresponding to the tooth plate 16. The end of the insert shaft 19 away from the gear 20 extends to the inside of the sub-packaging box 11, and a partition plate 21 is fixedly connected to the outside of the insert shaft 19, which engages with the gear 20 through the tooth plate 16, thereby completing the swing of the insert shaft 19 inside the sub-packaging box 11, so that the partition plate 21 blocks one group of the sub-packaging boxes 11, so that when the spray gun is used, the paint inside the other group of sub-packaging boxes 11 will not leak out.

[0038] In this embodiment, the implementation scenario is specifically as follows: when a small-caliber nozzle 8 is needed, the sleeve 910 is slid to the right to extend the airbag 909, and the impact shaft 908 is driven to move with the airbag 909, so that the spring 903 is compressed, and the main shaft 902 slides inside the sleeve 7, and then the fixed plate 904 moves with the main shaft 902, so that the nozzle 8 is separated from the inside of the accommodating groove 905. Due to the inclined design of the extension tube 901, in order to cooperate with the movement of the main shaft 902, the top of the fixed plate 904 also presents an inclined design, so that the first ball 906 falls to the inclined surface of the fixed plate 904 and the extension tube 901, thereby releasing the squeeze on the nozzle 8, easily taking out the nozzle 8, and filling the two different pigments into the packaging box 11. The interior of the sub-packaging box 11 is respectively inserted into the interior of the sub-packaging box 11 through the connecting tube 12, and the internal pigment is conducted to the interior of the extension shaft 3 through the pump. By rotating the horizontal shaft 13, the turntable 14 drives the connecting rod to rotate, so that the track 15 follows the movement of the connecting rod and makes left and right translation motion, so that the tooth plate 16 slides back and forth inside the slide rail 17, and the tooth plate 16 engages with the gear 20 to complete the swing of the plug-in shaft 19 inside the sub-packaging box 11, so that the partition plate 21 blocks one group of the sub-packaging boxes 11, so that when the spray gun is used, the pigment inside the other group of sub-packaging boxes 11 will not leak out.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
