[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 and Figure 3 The utility model provides an embodiment: a detachable spray head for a powder spraying machine, comprising a spray head shell 1, a plurality of spray holes 2 are provided on the front side of the spray head shell 1, a fixed tube 3 is fixedly connected to the bottom of the spray head shell 1, a connecting tube 4 is slidably connected to the outside of the fixed tube 3, a rotating sleeve 5 is rotatably connected to the outside of the connecting tube 4, a plurality of slide grooves 6 are provided inside the connecting tube 4, a plug-in block 7 is slidably connected to one end of the slide groove 6 near the fixed tube 3, a baffle 8 is slidably connected to one side of the slide groove 6 near the rotating sleeve 5, a thin rope 10 is provided between the baffle 8 and the rotating sleeve 5, a spring 9 is sleeved on the outer side of the thin rope 10, and an anti-blocking component is provided inside the spray head shell 1.

[0031] Specifically, a plurality of spray holes 2 are provided on the front side of the nozzle housing 1, ensuring uniform and efficient spraying operation. The outside of the fixed tube 3 is slidably connected to the connecting tube 4, so that the nozzle can be easily disassembled when it needs to be repaired or replaced, and the outside of the connecting tube 4 is rotatably connected to the rotating sleeve 5, further increasing the flexibility of disassembly and assembly. A plurality of slide grooves 6 are provided inside the connecting tube 4, which not only provide space for other components to move, but also enhance the stability of the overall structure. The end of the slide groove 6 close to the fixed tube 3 is slidably connected to the plug block 7, and the side close to the rotating sleeve 5 is slidably connected to the baffle 8, making the nozzle assembly more firm and disassembly more convenient. A thin rope 10 is provided between the baffle 8 and the rotating sleeve 5. A spring 9 is provided on the outside of the thin rope 10, so that the baffle 8 can move flexibly when subjected to external force, and can be quickly reset by the elastic restoring force of the spring 9. An anti-blocking component is also provided inside the nozzle housing 1 to prevent large pieces of powder from blocking the nozzle hole, ensuring the continuity and stability of the spraying operation.

[0032] Reference Figure 1 and Figure 2The anti-blocking component includes a push rod 11, the outside of the push rod 11 is slidably connected to the inside of the nozzle housing 1, the front side of the push rod 11 is fixedly connected to a moving plate 12, the front side of the moving plate 12 is fixedly connected to a plurality of needles 13, and a spring 14 is arranged between the moving plate 12 and the nozzle housing 1.

[0033] Specifically, the anti-blocking assembly is mainly composed of a push rod 11, a movable plate 12, a needle 13, and a spring 14. The push rod 11, as a driving component of the anti-blocking assembly, is slidably connected to the inside of the nozzle housing 1 so that the push rod 11 can easily move forward and backward inside the nozzle housing 1 when needed, thereby driving the entire anti-blocking assembly to work. The front side of the push rod 11 is firmly connected to the movable plate 12, so that the push rod 11 can drive the movable plate 12 to move synchronously when moving. A plurality of needles 13 are fixedly connected to the front side of the movable plate 12. These needles 13 are neatly arranged, sharp and powerful, and can effectively clear the blocked spray hole 2. A spring 14 is provided between the movable plate 12 and the nozzle housing 1. The existence of the spring 14 not only provides a stable support for the movable plate 12, but also enables the movable plate 12 to quickly reset after clearing the spray hole 2 through its elastic restoring force when the push rod 11 pushes the movable plate 12 forward, so as to prepare for the next anti-blocking operation.

[0034] Reference Figure 1 - Figure 3 The side end of the push rod 11 is fixedly connected with a handle 15, one end of the thin rope 10 is fixedly connected to the side of the baffle 8 away from the fixed tube 3, and the other end of the thin rope 10 is fixedly connected to the inner wall of the rotating sleeve 5, one end of the spring 19 is fixedly connected to the side of the baffle 8 away from the rotating sleeve 5, and the other end of the spring 19 is fixedly connected to the side of the plug-in block 7 away from the fixed tube 3, the plug-in block 7 passes through the connecting tube 4 and is plugged into the fixed tube 3, the outer side of the movable plate 12 is slidably connected to the inside of the nozzle housing 1, one end of the spring 2 14 is fixedly connected to the inner wall of the nozzle housing 1, and the other end of the spring 2 14 is fixedly connected to the middle of the movable plate 12.

[0035] Specifically, the handle 15 is fixedly connected to the side end of the push rod 11, which greatly enhances the convenience of operation. The operator can easily push the push rod 11 through the handle 15, thereby realizing the anti-blocking operation of the nozzle 2. One end of the string 10 is fixedly connected to the side of the baffle 8 away from the fixed tube 3, and the other end is fixedly connected to the inner wall of the rotating sleeve 5, so that the rotation of the rotating sleeve 5 can be transmitted to the baffle 8 through the string 10, thereby realizing the remote control of the baffle 8, which not only enhances the detachability of the nozzle, but also makes the disassembly process more flexible and convenient. The setting of the spring 19 is to ensure the stability and reset ability of the baffle 8 during the movement. One end of it is fixedly connected to the side of the baffle 8 away from the rotating sleeve 5, and the other end is fixedly connected to the side of the plug-in block 7 away from the fixed tube 3, so that the spring 19 can provide the necessary elastic support when the baffle 8 moves, and when the baffle 8 needs to be reset, the baffle 8 is quickly pulled back to its original position through its elastic restoring force. The plug-in block 7 makes the connection between the connecting tube 4 and the fixed tube 3 more firm and reliable. The plug-in block 7 can penetrate the connecting pipe 4 and be plugged into the inside of the fixed pipe 3, thereby ensuring a tight connection between the two. This connection method is not only simple and easy, but also can effectively prevent the connecting pipe 4 and the fixed pipe 3 from loosening or falling off during use. The setting of the spring 2 14 provides necessary support for the resetting of the movable plate 12. One end of the spring 2 14 is fixedly connected to the inner wall of the nozzle housing 1, and the other end is fixedly connected to the middle of the movable plate 12. This connection method enables the spring 2 14 to provide the necessary elastic support when the movable plate 12 moves, and when the movable plate 12 needs to be reset, the movable plate 12 is quickly pulled back to its original position through its elastic restoring force. This not only improves the efficiency of the anti-blocking operation, but also extends the service life of the nozzle.

[0036] Working principle: when the nozzle needs to be replaced, the rotating sleeve 5 is rotated to pull the thin rope 10, and then the plug-in rod 7 is pulled, and then the spring 1 9 is compressed until the plug-in rod 7 completely leaves the fixed tube 3. At this time, the replacement is completed. When a new nozzle needs to be installed, the fixed tube 3 is inserted into the connecting tube 4. At this time, the rotating sleeve 5 is released. Under the action of the spring 1 9, the plug-in rod 7 is pushed to be re-inserted into the fixed tube 3. At the same time, the thin rope 10 will pull the rotating sleeve 5 to rotate and return to its original position. At this time, the installation is completed. When the spray hole 2 is blocked by powder, pressing the push rod 11 drives the movable plate 12 and the needle 13 to move until the needle 13 is completely exposed from the spray hole 2. At this time, the push rod 11 is released, and the movable plate 12 and the push rod 11 are driven to reset under the action of the spring 14 to complete the dredging of the spray hole 2.
