[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0023] Example 1

[0024] refer to Figures 1-3 A powder dispensing machine includes a dispensing machine body 1 and a filling head 2. The dispensing machine body 1 is provided with a discharge pipe 11, and elastic telescopic members 3 are provided on both sides of the discharge pipe 11. The filling head 2 is provided with a fixing part 21 corresponding to the elastic telescopic member 3. The filling head 2 is detachably inserted into the discharge pipe 11 through the fixing part 21 cooperating with the elastic telescopic member 3. The dispensing machine body 1 is also provided with a swing mechanism 4. The swing mechanism 4 can simultaneously compress the elastic telescopic member 3 in a swinging manner, so that the filling head 2 moves downward and separates from the discharge pipe 11.

[0025] It should be noted that the dispensing machine body 1 mentioned in this embodiment can be a powder dispensing machine well known to those skilled in the art, and specifically refer to the dispensing machine disclosed in Chinese Patent CN104229164A.

[0026] Under this design, when the filling head 2 needs to be replaced, the operator pulls the swing mechanism 4 to make the swing mechanism 4 contact the elastic telescopic member 3, and under continuous pulling, the elastic telescopic members 3 located on both sides of the discharge pipe 11 are compressed, causing the filling head 2 to descend and separate from the discharge pipe 11. At this time, the operator can remove the filling head 2 from the elastic telescopic member 3, connect the filling head 2 of the required diameter to the elastic telescopic member 3, and finally release the swing mechanism 4 so that the filling head 2 can be inserted into the discharge pipe 11.

[0027] It should also be noted that the maximum extension stroke of the elastic telescopic component 3 is greater than the length of the overlapping portion of the filling head 2 and the discharge pipe 11. In other words, the filling head 2 separates from the discharge pipe 11 before the elastic telescopic component 3 extends to its maximum stroke.

[0028] In this embodiment, the elastic telescopic member 3 includes a fixed plate 31, a connecting post 32, a spring 33, a movable plate 34, and an adjusting nut 35. The fixed plate 31 is connected to the side of the discharge pipe 11. The connecting post 32 is movably inserted through the fixed plate 31. One end of the connecting post 32 is provided with a hook portion 321 for cooperating with the fixed part 21. The spring 33 and the movable plate 34 are both sleeved on the connecting post 32, and the two ends of the spring 33 abut against the fixed plate 31 and the movable plate 34 respectively. The other end of the connecting post 32 is provided with a thread. The adjusting nut 35 is threadedly connected to the other end of the connecting post 32 and contacts the movable plate 34.

[0029] Specifically, apart from the fixed plate 31, all other components are movable. In actual use, the spring 33 is always in a compressed state, so the spring 33 will always push the movable plate 34. Under the restriction of the adjusting nut 35, it is equivalent to the spring 33 always pushing the connecting column 32 through the movable plate 34, so that the hook part 321 is in close contact with the fixed plate 31, pulling the filling head 2. When the swing mechanism 4 is pulled, the swing mechanism 4 contacts the top of the connecting column 32 and presses down the connecting column 32, so that the movable plate 34 compresses the spring 33. The connecting column 32 and the hook part 321 move down together, and under the drive of the hook part 321, the filling head 2 moves down and separates from the discharge pipe 11. At this time, the operator can remove the filling head 2.

[0030] Preferably, the hook part 321 includes a block 3211 and a plate 3212 connected to one side of the block 3211. The free end of the plate 3212 is bent. The block 3211 is connected to one end of the connecting post 32. When the plate 3212 is engaged with the fixing part 21, the block 3211 abuts against the fixing plate 31.

[0031] In practical applications, the function of the block 3211 is to provide support for the plate 3212, and it can also cooperate with the fixing plate 31 to limit the position. That is, when the block 3211 abuts against the plate 3212, the filling head 2 is installed in place.

[0032] Furthermore, the fixing part 21 includes a connecting piece 211 connected to the filling head 2, and the top of the connecting piece 211 is provided with a bend that matches the plate 3212. The bend on the plate 3212 and the bend on the connecting piece 211 cooperate to achieve the hooking effect, and the bending process is easy.

[0033] In this embodiment, the swing mechanism 4 includes a U-shaped rod 41. The dispensing machine body 1 is provided with symmetrically arranged hinge members 12. The two ends of the U-shaped rod 41 are respectively hinged to the hinge members 12. The hinge members 12 are also provided with elastic members 123 for limiting the downward movement of the U-shaped rod 41 due to its own weight. The discharge pipe 11 is located in the area enclosed by the U-shaped pipe.

[0034] Specifically, without external force, the U-shaped rod 41 will not descend due to its own weight. The operator needs to provide external force to drive the U-shaped rod 41 to swing, so that the side walls of the two vertical parts on the U-shaped rod 41 contact the elastic telescopic members 3 on both sides of the discharge pipe 11, thereby compressing the elastic telescopic members 3 at the same time.

[0035] Furthermore, the U-shaped rod 41 is provided with a pressure block that matches the elastic telescopic member 3. By adding the pressure block, it is ensured that the U-shaped rod 41 can accurately press against the elastic telescopic member 3 when it swings. In a preferred embodiment, the pressure block is made of an elastic material, specifically rubber.

[0036] In this embodiment, the hinge 12 includes symmetrically arranged connecting plates 121 and a fixed shaft 122 connecting the symmetrically arranged connecting plates 121. The end of the U-shaped rod 41 is rotatably connected to the fixed shaft 122. An elastic element 123 is sleeved on the fixed shaft 122 and located on both sides of the end of the U-shaped rod 41. One end of the elastic element 123 is connected to the connecting plate 121, and the other end is connected to the end of the U-shaped rod 41. Preferably, the elastic element 123 is a torsion spring.

[0037] Under the constraint of the torsion spring, the U-shaped rod 41 is kept at rest when no external force is applied, rather than hanging freely. This prevents the U-shaped rod 41 from constantly pressing against the elastic telescopic member 3. The fixed shaft 122 provides a fulcrum for the swing of the U-shaped rod 41. As for the hinge member 12, the connecting plate 121 and the fixed shaft 122, they are common knowledge in the art, so they will not be described in detail in this embodiment.

[0038] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements or modifications can be made without departing from the principle of this application, and these improvements or modifications should also be considered within the scope of protection of this application.
