[0002] Powder coating is a solid powdered synthetic resin coating composed of solid resin and pigments, fillers and additives. The processing of powder coating first requires mixing and stirring the raw materials so that the raw materials can be mixed evenly. In order to ensure the uniform mixing and stirring of the raw materials, existing mixers mostly adopt longitudinal reciprocating or horizontal reciprocating mixing directions, which are faster and more uniform than traditional mixers that stir in a single rotation direction.

[0024] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural methods and implementation methods. Therefore, the following specific embodiments and drawings are only illustrative of the technical solution of the present invention and should not be regarded as the entire present invention or as a limitation or restriction of the technical solution of the present invention.

[0025] Example 1

[0026] See also Figure 1 and Figure 2 , this embodiment introduces a mixing and stirring equipment for powder coating processing, which is mainly composed of a mixer body 1, a support frame 2 and a driving mechanism 3. The mixer body 1 includes a body, a stirring blade and a stirring motor. The stirring motor is installed on the side wall of the body, the stirring blade is placed horizontally inside the body, and the end is movably connected to the body, and one end of the stirring motor is connected to the stirring blade through a coupling. A flip-type cover is hinged on the top of the body, which can be opened manually, or a cylinder can be set on the side wall of the body to open the flip-type cover. A corresponding discharge port is provided at the bottom of the body, and an electromagnetic valve or an ordinary valve is provided on the discharge port for closing or opening the discharge port. In the initial state, the mixer body 1 is placed horizontally.

[0027] The support frame 2 includes a first bracket 21 and a second bracket 22. The first bracket 21 is inside and the second bracket 22 is outside. The second bracket 22 is higher than the first bracket 21. The top of one side of the first bracket 21 is hinged to the bottom of one side of the mixer body 1. A driving mechanism 3 is provided between the other side of the first bracket 21 and the other side of the mixer body 1.

[0028] The drive mechanism 3 includes a lifting cylinder 31 and a sling 32. The lifting cylinder 31, serving as the driving portion of the drive mechanism 3, has a fixed end movably mounted on the first bracket 21. The movable end of the lifting cylinder 31 is movably connected to the mixer body 1. Extension or contraction of the lifting cylinder 31 drives the longitudinal rotation of the mixer body 1. When the lifting cylinder 31 extends, the mixer body 1 rotates upward about the hinged joint between the mixer body 1 and the first bracket 21. When the lifting cylinder 31 contracts, the mixer body 1 rotates downward.

[0029] The hanging member 32 is used to connect the mixer body 1 to the second bracket 22 to provide auxiliary support for the mixer body 1. The hanging member 32 includes a drum 321 and a connecting rope 322. The drum 321 is mainly composed of a limit frame, a cylinder and a limit bolt. The limit frame is similar to a U-shape and is installed on the top of the second bracket 22. The cylinder is located inside the limit frame, and the central axis of the cylinder is movably connected to the limit frame. The connecting rope 322 is wrapped around the cylinder, one end is fixed to the cylinder, and the other end is connected to the body of the mixer body 1. In order to facilitate the connection between the body of the mixer body 1 and the connecting rope 322, a corresponding protrusion is provided on the side wall of the body for fixing the end of the connecting rope 322. The limit bolt is threadedly connected to the limit frame and is close to the end face of the cylinder. It should be emphasized that a hole is opened on the end face of the cylinder to match the end of the limit bolt, and the number of the limit bolt is at least one. The connecting rope 322 between the cylinder and the mixer body 1 is reserved for a certain length to cooperate with the extension and retraction of the jacking cylinder 31.

[0030] When the length of the connecting rope 322 needs to be adjusted, the limiting bolt can be loosened to allow the end of the limiting bolt to leave the end surface of the cylinder, and the cylinder can be rotated to loosen the connecting rope 322 to match the longitudinal rotation range of the mixer body 1. The rotation of the cylinder can be manual, driven by a motor, or driven by other linkage components.

[0031] When stirring is required, the mixer body 1 is started, and the lifting cylinder 31 is started at the same time. The lifting cylinder 31 drives the mixer body 1 to rotate longitudinally, and the material at the bottom end of the body moves toward the two ends of the body so that it can contact the stirring blades and be turned and stirred by the stirring blades. In addition, the body has discharge pipes at the bottom of both sides in the length direction of the first bracket 21, and the discharge pipes are provided with valves. When the material inside the body needs to be emptied, after the material is discharged from the discharge port, when the lifting cylinder 31 drives the mixer body 1 to cause the mixer body 1 to shift longitudinally, the lower discharge pipes on both sides of the body can be opened to discharge the material remaining at the bottom end of the body, thereby achieving the purpose of emptying the material inside the body.

[0032] Example 2

[0033] like Figure 3 As shown, this embodiment introduces a mixing and stirring device for powder coating processing, which has basically the same structure as the mixing and stirring device for powder coating processing introduced in Example 1. The difference is that the driving mechanism 3 of this embodiment is mainly composed of a forward and reverse motor 34, a hanging member 32 and an auxiliary support member 33. The fixed end of the forward and reverse motor 34 is installed on the top of the second bracket 22, and the output shaft is fixedly connected to the hanging member 32. The hanging member 32 can adopt the same structure as Example 1, or other structures can be adopted. For example, only a winding drum and a connecting rope 322 are required. The central axis of the winding drum is connected to the output shaft of the forward and reverse motor 34, one end of the connecting rope 322 is connected to the winding drum, and the other end is connected to the body of the mixer main body 1, and the connecting rope 322 is wound on the winding drum. The connecting ropes 322 on both sides of the body are loosened or tightened to realize the longitudinal rotation of the body.

[0034] like Figure 4As shown, the auxiliary support member 33 is used to assist in supporting the mixer body 1 and cooperate with the longitudinal rotation of the mixer body 1. The auxiliary support member 33 includes a support column 331, a support rod 332, a limit ring 333 and a spring 334. The support column 331 is composed of a sleeve and an end cover. The two ends of the sleeve are open, one end of which serves as the bottom end of the sleeve and the inner wall is provided with an internal thread for threaded connection with the end cover. The end cover closes the bottom end of the sleeve, and the sleeve is fixed to the first bracket 21. The bottom end of the support column 331 is fixed to the first bracket 21 and is located below the other side opposite to the hinged side of the mixer body 1 and the first bracket 21. The diameter of the support rod 332 is smaller than the inner diameter of the sleeve. One end of the support rod 332 is located inside the support column 331, and the other end is located above the support column 331 and in contact with the bottom of the mixer body 1. The outer diameter of the retaining ring 333 is consistent with the inner diameter of the sleeve, and the inner diameter of the retaining ring 333 is consistent with the diameter of the support rod 332. The retaining ring 333 is fixedly mounted on the outer surface of the support rod 332, so that the retaining ring 333 is in contact with the inner wall of the support column 331. The spring 334 is located between the bottom of the support column 331 and the retaining ring 333. The spring 334 contacts the end cap and is used to push the retaining ring 333 upwards from the support column 331, ensuring that the top of the support rod 332 is in contact with the bottom of the machine body. To facilitate the longitudinal rotation of the top of the support rod 332 with the machine body, the top of the support rod 332 is curved or spherical.

[0035] When mixing is required, the raw materials are placed inside the machine body, and the mixer body 1 is started for mixing. The forward and reverse motors 34 are driven to rotate the mixer body 1 longitudinally. The forward and reverse motors 34 located above the support column 331 serve as the main driving component. When the forward and reverse motors 34 rotate, the connecting rope 322 is tightened, and the end of the mixer body 1 connected to the connecting rope 322 is raised. When the connecting rope 322 is loosened, the end of the mixer body 1 connected to the connecting rope 322 is lowered, and the other forward and reverse motor 34 rotates in coordination. Alternatively, the connecting rope 322 connected to it is left with a certain length to coordinate with the rotation of the mixer body 1.

[0036] This embodiment has the same beneficial effects as embodiment 1.

[0037] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the scope of protection of the present invention.
