[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] like Figure 1 As shown, in an illustrative embodiment of the angle-adjustable mixer of the utility model, the angle-adjustable mixer includes a base 1 , a workbench 2 , a casing 3 , a mixing barrel 4 , a cover 5 , a mixing mechanism 6 and a positioning pin 7 .

[0030] The workbench 2 is hingedly mounted on the base 1 and is equipped with a first drive motor 8. The front side of the base 1 has an inclined support portion 9. The casing 3 is mounted on the workbench 2. The mixing barrel 4 is rotatably mounted on the front side of the workbench 2 and is located in the casing 3. The first drive motor 8 drives the mixing barrel 4 to rotate. The support portion 9 is located below the mixing barrel 4. The cover 5 is mounted on the casing 3 and covers the port of the mixing barrel 4. The stirring mechanism 6 is mounted on the cover 5 and has a second drive motor 10 and an agitator 11. The agitator 11 extends into the mixing barrel 4. The second drive motor 10 drives the agitator 11 to rotate. The agitator 11 is located at the rear side of the mixing barrel 4. The positioning pin 7 passes through the first pin hole 12 opened in the base 1 and the second pin hole 13 opened in the workbench 2. A plurality of first pin holes 12 or second pin holes 13 are arranged on a circle with the hinge point of the base 1 and the workbench 2 as the center.

[0031] By hinged connection with the base 1, the workbench 2 is tilted, so that the mixing barrel 4 is adjusted to the desired tilt angle, and the positioning pin 7 is inserted into the first pin hole 12 and the second pin hole 13 at the corresponding position to fix the workbench 2 and the base 1, so that the mixing barrel 4 is fixed at the current tilt angle. The support part 9 can reduce the height of the front side of the base 1, and provide a moving space for the front part of the workbench 2 that sinks downward due to the tilt. The mixing barrel 4 is located in the front part of the workbench 2, and its gravity can make the front part of the workbench 2 sink downward, reducing the difficulty of tilting the workbench 2.

[0032] The material is put into the mixing barrel 4, the machine cover 5 is closed, the agitator 11 is placed in the mixing barrel 4, the first drive motor 8 and the second drive motor 10 are turned on, and under the drive of the first drive motor 8 and the second drive motor 10, the agitator 11 and the mixing barrel 4 are rotated.

[0033] Since the mixing barrel 4 is tilted, the material itself has fluidity, and flows downward to the front side of the mixing barrel 4 under the action of gravity, that is, the material flows radially in the mixing barrel 4. Furthermore, since the mixing barrel 4 rotates, the material flowing to the front side of the mixing barrel 4 moves from the outside to the back side of the mixing barrel 4 along with the rotating mixing barrel 4, that is, the material moves in the circumferential direction in the mixing barrel 4. Since the agitator 11 is located at the back side of the mixing barrel 4, when the material moves to the back side of the mixing barrel 4, it is stirred by the rotating agitator 11, so as to be fully mixed.

[0034] The weaker the fluidity of the material, the greater the inclination angle of the mixing barrel 4 needs to be in order to allow the material to flow radially to the front side of the mixing barrel 4 within the set time. Therefore, according to the fluidity characteristics of different types of materials, the inclination angle of the mixing barrel 4 is set accordingly, so that each type of material can flow radially to the front side of the mixing barrel 4 within the set time, and then move to the rear stirrer 11 along the circumference of the mixing barrel 4 in time, ultimately ensuring that different types of materials can have sufficient stirring efficiency to meet the experimental mixing of materials with different characteristics.

[0035] In addition, the agitator 11 and the mixing barrel 4 rotate at the same time, so that the agitator 11 not only rotates on itself, but also revolves relative to the mixing barrel 4. The material moves radially and circumferentially in the mixing barrel 4 at the same time. At the same time, the agitator 11 causes the material to further rotate so that the material is fully mixed. There is no dead corner of the mixing action inside the mixing barrel 4, which improves the mixing effect.

[0036] In the above-mentioned schematic embodiment, the workbench of the adjustable angle mixer is hinged on the base, and the mixing barrel on the workbench can be fixed at different inclination angles by positioning pins, so that the mixing barrel can adjust the inclination angle for materials with different characteristics, so that it can be used in more experimental scenarios without customization, and the mixing barrel and the agitator can rotate at the same time, which enhances the stirring effect and solves the problem that the current laboratory stirring equipment has a single usage scenario and needs to be customized.

[0037] In some embodiments, a sweeper 14 is installed on the machine cover 5 , and the sweeper includes a first scraper 141 and a second scraper 142 .

[0038] The first scraper 141 is parallel to the axis of the mixing barrel 4 and has a clearance fit with the inner wall of the mixing barrel 4 . The second scraper 142 is installed at the bottom end of the first scraper 141 and is parallel to the bottom surface of the mixing barrel 4 and has a clearance fit therewith.

[0039] During the rotation of the mixing barrel 4, the sweeper 14 fixed on the machine cover 5 moves relative to the mixing barrel 4, the first scraper 141 scrapes the inner wall of the mixing barrel 4, and the second scraper 142 scrapes the bottom surface of the mixing barrel 4, thereby preventing the material from adhering to the inner wall of the mixing barrel 4, ensuring the fluidity of the material, and then ensuring that the material can be fully mixed.

[0040] In some embodiments, the sweeper 14 is located in the middle of the mixing barrel 4, so as to ensure that the material can pass through the sweeper 14 and scrape off the material adhering to the inner wall of the mixing barrel 4 as the mixing barrel 4 moves from the front circumference to the rear side or from the rear circumference to the front side, so that the material can approach the center of the mixing barrel 4 and be directly stirred by the agitator 11, or the material can flow radially in the mixing barrel 4 after being stirred by the agitator 11, so that all the materials in the mixing barrel 4 can be fully stirred by the agitator 11 and fully moved in multiple directions, ultimately ensuring that the materials can be fully mixed.

[0041] In some embodiments, the agitator 11 includes a rotating shaft 111 and a plurality of stirring blades 112 vertically mounted on the rotating shaft, and the stirring blade 112 located at the bottom end of the rotating shaft 111 has a stirring claw 113, and the stirring claw 113 is located at the outer end of the corresponding stirring blade 112 and extends toward the bottom surface of the stirring barrel 4. The stirring claw 113 extending toward the bottom surface of the stirring barrel 4 can enhance the stirring effect of the agitator 11 on the material below it, increase the stirring effect range, and enable the stirring blade 112 to chop both radially flowing and axially flowing materials, further enhancing the stirring effect.

[0042] In some embodiments, the cover 5 is provided with a plug 15, which extends into the mixing barrel 4, and its outer wall is gap-matched with the inner wall of the mixing barrel 4. A pressing edge 16 is provided on the outer wall of the plug 15, and the pressing edge 16 is pressed on the port of the mixing barrel 4.

[0043] The cover plug 15 extending into the mixing barrel 4 can enhance the sealing effect of the cover 5 on the mixing barrel 4, and can also limit the axial position of the mixing barrel 4, so that the mixing barrel 4 rotates more smoothly and is less likely to shake in the radial direction, thereby reducing the vibration of the equipment during mixing. When the mixing barrel 4 rotates, the pressure edge 16 slides on the port to keep it pressed, maintaining the sealing stability of the rotating mixing barrel 4 and preventing material from leaking during mixing.

[0044] In some embodiments, the rear end of the cover 5 is hingedly mounted on the housing 3 so that the cover 5 can be flipped open, thereby improving the convenience of opening and closing operations of the cover 5.

[0045] In some embodiments, a buffer pad 17 is installed on the support portion 9 to prevent the front of the workbench 2 from colliding with the base 1 under the downward pressure of the mixing barrel 4 after the positioning pin 7 is pulled out.

[0046] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0047] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for which protection is requested in the utility model.
