[0002] Plastic powder additives are usually powdered solids, which are added to pigments or coatings to enhance their functions, such as enhancing leveling, increasing moiré effects, etc.

[0003] When producing plastic powder additives, stirring and mixing equipment is required to fully stir and mix various powder raw materials together. For example, the patent application document with publication number CN 111249954A discloses a special stirring and mixing machine for powder materials. The stirring tank of this stirring and mixing machine is fixed. By rotating the stirring shaft in the stirring tank, the stirring paddle is driven to rotate to achieve stirring and mixing. This stirring and mixing equipment also has the following problems: In order to ensure that the stirring paddle on the stirring shaft can rotate safely and smoothly, a certain gap must be left between the stirring paddle and the inner wall of the stirring tank, which makes it difficult to fully mix the powder in the gap. Summary of the invention

[0004] In view of this, an object of the present invention is to provide a powder mixer which can fully mix powders and can be used for producing plastic powder additives.

[0005] The technical solution adopted by the present invention to solve the technical problem is:

[0025] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0026] It should be noted that all directional indications in the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. In addition, the descriptions of "preferred", "sub-preferred", etc. in the present invention are only used for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined as "preferred" or "sub-preferred" may explicitly or implicitly include at least one such feature.

[0027] Reference Figures 1 to 9 The present invention proposes a powder mixer that can be used to produce plastic powder additives, including a frame 1, a swing frame 2 rotatably arranged on the frame 1, and a swing frame driver 11 capable of driving the swing frame 2 to swing, a powder container 3 and a power mechanism capable of driving the powder container 3 to rotate relative to the swing frame 2 are arranged on the swing frame 2, and the rotation axis of the powder container 3 intersects or is not in the same plane with the swing axis of the swing frame 2.

[0028] In a preferred embodiment of the present invention, the rotation axis of the powder container 3 and the swing axis of the swing frame 2 are not in the same plane and are perpendicular to each other. The working principle of this embodiment is: after the powder raw material is placed in the powder container 3, it should not be filled up, but a part of the space should be reserved, for example, the volume of the powder filled in the powder container 3 is 1 / 2 or 2 / 3 of its volume, and when the powder container 3 is driven by the power mechanism to rotate, the powder therein can be mixed. While the powder container 3 is rotating, the swing frame 2 continuously swings back and forth, or swings intermittently, so that the powder in the powder container 3 can be fully mixed together.

[0029] The swing frame driver 11 can be a cylinder, a motor, an oil cylinder, etc. In one embodiment of the present invention, the swing frame 2 is hinged to the frame 1, and the swing frame driver 11 is a cylinder, the lower end of the cylinder body of the cylinder is hinged to the frame 1, and the upper end of the output shaft of the cylinder is hinged to the swing frame 2. The front end and the rear end of the swing frame 2 are both provided with connecting shafts 21, and the two connecting shafts 21 are respectively connected to the frame 1 through bearings.

[0030] Reference Figure 1 and Figure 3 The power mechanism includes a plurality of rollers 41 arranged side by side on the swing frame 2 and a rotary driver 42 capable of driving all the rollers 41 to rotate synchronously. The powder container 3 is placed between two adjacent rollers 41. When the rollers 41 rotate, the powder container 3 is driven to rotate by friction. Specifically, the rotary driver 42 is a reduction motor, and a driving gear 43 is connected to the output end of the reduction motor. The left ends of all the rollers 41 are connected to driven gears 44. The driving gear 43 and all the driven gears 44 are connected through the same synchronous toothed belt 45.

[0031] The arrangement of the rotating roller 41 may include the following two embodiments.

[0032] Reference Figure 6 As an embodiment 1 of the roller 41, the powder container 3 has a cylindrical outer barrel 31, and the roller 41 includes a rotating shaft 411 and a barrel supporting member 412 coaxially mounted on the rotating shaft 411, and the outer side wall of the barrel supporting member 412 has a cylindrical surface in contact with the outer barrel 31.

[0033] Reference Figures 7 to 9 As the second embodiment of the roller 41, the powder container 3 has a cylindrical outer barrel 31, and the roller 41 includes a rotating shaft 411 and an eccentric wheel 413 sleeved on the rotating shaft 411. The outer wall of the eccentric wheel 413 has a cylindrical surface in contact with the outer barrel 31, and the axis of the cylindrical surface is parallel to the axis of the rotating shaft 411. The advantage of this embodiment is that the eccentric wheel 413 with a circular cross section is used to drive the powder container 3 to rotate, so that the powder container 3 will have a certain jump in the up and down directions while rotating, which can further improve the powder mixing efficiency. In addition, since the outer side surface of the eccentric wheel 413 is a cylindrical surface, the distance and relative position relationship between the center line of the powder container 3 and the center line of the eccentric wheel 413 remain basically unchanged when the powder container 3 rotates, which can prevent the powder container 3 from falling due to changes in this position relationship.

[0034] The powder container 3 comprises an outer barrel 31 with openings at both ends, an outer barrel cover 32 detachably mounted at both ends of the outer barrel 31, and an inner barrel 33 detachably mounted inside the outer barrel 31. Preferably, the outer barrel 31 and the outer barrel cover 32 are connected by an elastic buckle lock, wherein the buckle body 71 of the elastic buckle lock is fixed on the outer barrel cover 32, and the locking tongue assembly 72 of the elastic buckle lock is mounted on the outer barrel 31; the inner barrel 33 comprises a barrel body 331, an inner barrel cover 332, and a handle 333 rotatably mounted on the barrel body 331.

[0035] Reference Figures 1 to 3, both ends of all the rollers 41 are hinged to the left and right parts of the swing frame 2 respectively, and the left and right ends of the swing frame 2 are provided with limit members capable of supporting the powder container 3. All the limit members include a limit frame 81 and a ball 82 rotatably arranged on the limit frame 81 and abutting against the powder container 3. Specifically, a groove is arranged on the limit frame 81, and the inner side surface of the groove is a spherical surface. The ball 82 is installed in the groove and rotatably cooperates with the groove. The setting of the limit member can prevent the powder container 3 from slipping when the swing frame 2 swings, and the design of the ball 82 can convert the sliding friction into rolling friction, thereby reducing the friction between the powder container 3 and the limit member.

[0036] In certain embodiments of the present invention, the power mechanism may also adopt other structural forms, for example, a sprocket may be used to replace the driving gear 43 and the transmission gear, and a chain may be used to replace the synchronous toothed belt 45.

[0037] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or directly or indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
