[0033] It should be noted that, in the description of this specification, the terms "upper", "lower", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention. The head and tail, as well as the front and back in this embodiment are based on the order of flow of the media, that is, the direction in which the media flows first is the front and the head. This is something that a person skilled in the art can understand, and will not be elaborated on here. In this embodiment, for the convenience of description, the X-direction, Y-direction and Z-direction are artificially defined, wherein the length direction of the rack is the X-direction, the height direction of the rack is the X-direction, the width direction of the rack is the Z-direction, and the XY plane is the plane enclosed by the X-direction and the XY plane, as shown in the figure. This is something that a person skilled in the art can understand, and will not be elaborated on here.

[0034] As shown in the figure, the present invention discloses a multi-degree-of-freedom offset material mixing test device, comprising a mixing barrel assembly and a stirring assembly. The mixing barrel assembly includes an inner barrel 2, wherein the inner barrel 2 and the stirring assembly as a whole can be driven to swing with a single degree of freedom within the XY plane; the stirring assembly can be driven to move in the X and Y directions, and the stirring assembly includes an agitator 4, wherein the agitator 4 is arranged such that its axis is offset from the central axis of the inner barrel 2, that is, the agitator 4 is eccentric relative to the inner barrel 2. In this embodiment, both the inner barrel 2 and the stirring assembly as a whole can swing with a single degree of freedom within the XY plane, which simulates material mixing at different inclination angles and provides effective and accurate guidance for studying the effects of different inclination angles on material mixing. In this embodiment, the eccentricity is based on the XZ plane, that is, on the XZ plane, the centers of the agitator 4 and the inner barrel 2 do not coincide and are offset from each other. This is well understood by those skilled in the art and will not be elaborated here.

[0035] In this embodiment, the mixing drum assembly also includes a working panel 3 and a frame 1. The inner drum 2 and stirring assembly are mounted on the working panel 3. The working panel 3 is mounted on the frame 1 in a manner that allows for oscillation with a single degree of freedom within the XY plane. Compared to driving the inner drum 2 and stirring assembly separately, mounting both on the working panel 3 simultaneously allows for tilting of the inner drum 2 and stirring assembly by driving the working panel 3 to swing, thus avoiding the tilt angle deviation that would otherwise affect the simulation results if driven separately. In this embodiment, the inner drum 2 is mounted on the working panel 3 in a manner that allows for oscillation about its own axis. A ring of transmission teeth is provided on the outer circumference of the top surface of the inner drum 2. The working panel 3 is equipped with a motor and a gear transmission pair, which drives the rotation of the inner drum 2 via the gear transmission pair. In this embodiment, the working panel 3 is driven to oscillate via an electric push rod 23 mounted on the frame 1. The two ends of the electric push rod 23 are hinged to the bottom of the frame 1 and the bottom surface of the X-direction end of the working plane, respectively. The extension and retraction of the electric push rod 23 controls the oscillation of the working plane.

[0036] In this embodiment, the working panel 3 is provided with a rotation support plate 22 at both ends along the Z direction, and each of the rotation support plates 22 is provided with a rotating shaft 17, and the two rotating shafts 17 are coaxially arranged. The frame 1 is provided with a side plate 14, and the working panel 3 is swingably provided on the side plate 14 of the frame 1 via the rotating shaft 17, and the swing range of the working panel 3 is 0° to 30°. In this embodiment, a locking plate 16 is also included. The rotation support plate 22 is provided with a limiting column, and the side plate 14 is correspondingly provided with a limiting slot 15. The limiting slot 15 is arc-shaped, and the limiting column passes through the limiting slot 15 and extends to the outside of the side plate 14. The locking plate 16 can be installed on the limiting column to lock the limiting column in the limiting slot 15. As shown in the figure, the limiting slot 15 in this embodiment is a plurality of concentric arcs. In this embodiment, in its initial position, the working plane is parallel to the XZ plane. When it swings to its extreme position, the angle between the working plane and the XZ plane is 30°. Correspondingly, the central angle α of the limiting slide 15 is set to 30° to limit its swing stroke. In this embodiment, an external thread can be provided on the limiting column. When the working plane is swung to the desired angle, the locking plate 16 is threadedly locked to the outer plate 14 using, for example, a butterfly nut. This achieves a clamping and limiting effect on the inner plate 14, thereby locking the inner cylinder 2 at the set angle. In this embodiment, a scale is also provided on the outer plate 14 to intuitively display the inclination angle of the working plane, facilitating adjustment.

[0037] In this embodiment, the stirring assembly further includes a cover plate 6 and a mounting seat 5. The cover plate 6 can be driven to move in the X and Y directions. The cover plate 6 is used to seal the inner cylinder 2. The stirrer 4 is mounted on the cover plate 6 via the mounting seat 5. The cover plate 6 is driven to move in order to seal the inner cylinder 2 or to open the inner cylinder 2 to add or remove materials. As shown in the figure, the stirrer 4 in this embodiment includes a capstan 402 for stirring and an agitator motor 401 for driving the capstan 402 to rotate. The agitator motor 401 is mounted on the mounting seat 5, and the capstan 402 passes through the mounting seat 5. During stirring, the cover plate 6 seals the inner cylinder 2, and the capstan 402 extends into the inner cylinder 2 for stirring.

[0038] In this embodiment, the mounting seat 5 is eccentrically arranged on the cover plate 6, and the mounting seat 5 is provided with a mounting hole 501 for mounting the agitator 4 in a manner that can rotate around its own axis, and the mounting hole 501 is eccentrically arranged on the mounting seat 5. The mounting seat 5 is rotatable, so that the eccentricity of the agitator 4 becomes adjustable. In conjunction with the swingable inner cylinder 2, it provides effective and accurate guidance for the mixing of materials under different inclination angles and different eccentricities, and facilitates the simulation of different test conditions. In this embodiment, the eccentricity of the agitator 4 is achieved through the mounting seat 5, and the mounting hole 501 is eccentric, so that the eccentric angle of the agitator 4 can be adjusted as long as the mounting seat 5 is rotated. In this embodiment, the cover shell is provided with an angle scale, and the angle scale corresponds to the position setting of the mounting seat 5. That is, the angle scale is arranged on the radial outside of the mounting seat 5, as shown in the figure, which can mark the rotation angle of the mounting seat 5 and achieve precise adjustment.

[0039] In this embodiment, an X-direction drive assembly and a Y-direction drive assembly are also included. The stirring assembly also includes a gantry. The working panel 3 is provided with a slide rail extending along the X-direction. The gantry includes a mounting frame 7, a guide rail 8 arranged along the Y-direction and mounted on the bottom surface of the mounting frame 7, and a sliding base 9 arranged at the end of the guide rail 8 and slidingly cooperating with the slide rail; the X-direction drive assembly includes a drive source I10 and a drive rod I11 mounted on the working panel 3, and the drive source I10 drives the sliding base 9 to slide along the slide rail through the drive rod I11; the Y-direction drive assembly includes a drive source II12 and a drive rod II13 mounted on the mounting frame 7, and the cover plate 6 is slidably mounted on the guide rail 8, and the drive source II12 drives the cover plate 6 to slide along the guide rail 8 through the drive rod II13. As shown in the figure, the drive source I10 and the drive source II12 in this embodiment are both servo motors, the drive rod I11 and the drive rod II13 are both screw rods, and the X-direction drive assembly and the Y-direction drive assembly in this embodiment are both provided in two groups, as shown in the figure. The sliding base in this embodiment is provided with a ball sleeve, which cooperates with the drive rod I11 in the X-direction drive assembly to drive the entire door frame and the cover plate 6 installed on the door frame to move in the X direction. A hole is provided in the cover plate 6 that is threadedly engaged with the drive rod II13. The Y-direction drive assembly directly drives the cover plate 6 to move in the Y direction through the drive rod II13. In this embodiment, there are four guide rails 8, and they are arranged symmetrically in pairs, as shown in the figure, to guide and limit the sliding of the cover plate 6.

[0040] In this embodiment, the working panel 3 is provided with a limit block 20, and the gantry is provided with a limit shell 21. The limit blocks 20 are provided in plurality along the X direction, and the limit shell 21 can be driven to move along the Y direction. The limit shell 21 engages with any of the limit blocks 20 to limit the gantry to the working panel 3. In this embodiment, the limit shell 21 is driven by a limit motor, and four limit blocks 20 are provided, which are divided into two groups and are respectively arranged at the positions of the two groups of X-direction drive components. In each group of limit blocks 20, one is used to limit the cover plate 6 and the gantry to the position of the inner cylinder 2 to ensure that the cover plate 6 can close the inner cylinder 2, and the other is used to limit the cover plate 6 and the gantry when the cover plate 6 is raised and away from the inner cylinder 2, so as to avoid hindering the staff from adding materials to the inner cylinder 2 or taking materials out of the inner cylinder 2. In this embodiment, a buffer 19 is also provided on the drive rod I11. The buffer 19 is connected to a sensor. When the drive source I10 drives the gantry toward the inner cylinder 2, the buffer 19 provides shock absorption when the cover plate 6 approaches the upper position of the inner cylinder 2. When the cover plate 6 reaches the upper position of the inner cylinder 2, the sensor detects and sends a signal to control the drive source I10 to stop, causing the cover plate 6 to stop above the inner cylinder 2. The limit motor then drives the limit housing 21 to move downward in the Y direction. The limit housing 21 is covered by the limit block 20 and engages with the limit block 20 to form a limit. Finally, the drive source II12 drives the cover plate 6 downward in the Y direction to cover the inner cylinder 2. The inclination angle of the working panel 3 can then be adjusted according to the test requirements, and various sensors for detection can be arranged, and the material mixing test can be started. How the buffer 19 performs buffering and how the sensor controls the start and stop of the motor are conventional techniques in the art and will not be elaborated here.

[0041] This embodiment also includes a cooling assembly 18, comprising an outer cylinder 24, a water inlet 26, a nozzle 25, a connecting pipe 27, and a water return port 28.

The water inlet 26 and the water return port 28 are both arranged on the bottom surface of the outer tube 24. The cooling water enters through the water inlet 26 and is then connected to each nozzle 25 through the connecting pipe 27.
