DETAILED DESCRIPTION
[0022] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.
[0023] The present application discloses a material mixing device, referring to Figure 1 、 Figure 2 and Figure 3 , including a barrel body 1, a feeding port is provided on the top of the barrel body 1, and a cover plate 2 is installed at the feeding port. A rotating shaft 3 is rotatably provided in the barrel body 1, and the axis of the rotating shaft 3 is horizontal. A first spiral blade 4 and a second spiral blade 5 are provided on the outer wall of the rotating shaft 3, and the outer diameter of the first spiral blade 4 is smaller than the outer diameter of the second spiral blade 5. A first discharge port is provided on one side of the barrel body 1, and a first discharge pipe 11 is welded to the first discharge port. A baffle 6 for opening / closing the first discharge port is movably provided in the barrel body 1, and a driving member for driving the rotating shaft 3 to rotate is also installed on the barrel body 1.
[0024] In this embodiment, multiple connecting rods are welded to the outer wall of the rotating shaft 3, and the first and second spiral blades 4 and 5 are welded and fixed to the connecting rods. The operator opens the cover 2 to pour material into the barrel 1. The driver then drives the rotating shaft 3 to rotate, causing the first and second spiral blades 4 and 5 to simultaneously stir the material. Once stirring is complete, the baffle 6 is opened to discharge the material from the first discharge pipe 11. This double-layer spiral blade design improves the stirring efficiency of the material within the barrel 1.
[0025] Furthermore, the spiral directions of the first spiral blade 4 and the second spiral blade 5 are opposite.
[0026] In the embodiment of the present application, the first spiral blade 4 can push the material near the axis inside the barrel body 1 to move, and the second spiral blade can push the material near the inner wall of the barrel body 1 inside the barrel body 1 to move. The two materials perform convection motion along the axis of the rotating shaft 3, forming a low-power and high-efficiency mixing environment, further improving the stirring efficiency of the material.
[0027] The driving member includes a driving motor 7, which is mounted on the outer wall of the barrel body 1. The output shaft of the driving motor 7 is transmission-connected to one end of the rotating shaft 3. Specifically, the output shaft of the driving motor 7 and the end of the rotating shaft 3 can be coaxially welded and fixed to achieve transmission.
[0028] Furthermore, the two ends of the rotating shaft 3 pass through the two side walls of the barrel body 1 respectively, and the side wall of the barrel body 1 is provided with an axial hole for the rotating shaft 3 to pass through. A seal 8 is installed at the axial hole to close the gap between the inner wall of the axial hole and the outer wall of the rotating shaft 3. The seal 8 includes a mounting seat 81, a sealing ring 82 and a sealing cover 83. The mounting seat 81 is bolted to the axial hole on the outer wall of the barrel body 1, and the end of the rotating shaft 3 passes through the mounting seat 81. The mounting seat 81 is provided with an annular groove for accommodating the sealing ring 82 on the side away from the barrel body 1. The sealing ring 82 is embedded in the annular groove and coaxially sleeved on the outer wall of the rotating shaft 3. The sealing cover 83 is coaxially sleeved on the outer wall of the rotating shaft 3 and connected to the side of the mounting seat 81 away from the barrel body 1. The two sides of the sealing ring 82 are respectively in compression contact with the sealing cover 83 and the inner bottom wall of the annular groove.
[0029] In the embodiment of the present application, the sealing cover 83 is connected to the mounting base 81 by bolts. Tightening the bolts causes the two sides of the sealing ring 82 to press against the sealing cover 83 and the inner bottom wall of the annular groove, respectively, so that the sealing ring 82 can be firmly installed in the mounting groove. The sealing ring 82 contacts the outer wall of the rotating shaft 3 to prevent impurities in the air from entering the interior of the barrel body 1 through the shaft hole.
[0030] Furthermore, the first discharge port is arranged on the side wall of the barrel body 1 away from the driving motor 7, the baffle 6 is horizontally slidably arranged on the side wall of the barrel body 1 where the first discharge port is located, and a cylinder 61 for driving the baffle 6 to slide to open / close the first discharge port is installed on the side wall of the barrel body 1, as shown in FIG. Figure 4 shown.
[0031] In the embodiment of the present application, the baffle 6 can be connected to the piston rod of the cylinder 61 by bolts, and the cylinder 61 can drive the baffle 6 to slide and open / close the first discharge port.
[0032] Reference Figure 5The cover plate 2 is overlapped at the opening of the barrel body 1. A plurality of positioning members 9 are installed on the barrel body 1 along the circumference of the cover plate 2 to limit the cover plate 2 from moving away from the opening. The positioning member 9 includes a rotating piece 91 rotatably mounted on the outer wall of the barrel body 1 and a press rod 92 slidably mounted on the rotating piece 91. A positioning column 911 is welded and fixed to the rotating piece 91. One end of the press rod 92 is movably mounted on the positioning column 911, and the other end of the press rod 92 is movably abutted against the top of the cover plate 2. A locking nut 93 is threadedly connected to the press rod 92 for abutting against the positioning column 911 and driving the press rod 92 to slide and abut against the cover plate 2.
[0033] In the embodiment of the present application, the operator rotates the rotating plate 91 to cause one end of the press rod 92 to overlap the cover plate 2, and then rotates the locking nut 93 to cause it to contact the positioning post 911. Since the positioning post 911 is fixed, when the locking nut 93 is further rotated, the locking nut 93 is blocked by the positioning post 911 and cannot slide. This allows the press rod 92 to slide relative to the locking nut 93, and drives the end of the press rod 92 to abut the cover plate 2.
[0034] In order to improve the discharge efficiency of the material, a second discharge port is opened at the bottom of the barrel body 1, and a second discharge pipe 12 is welded at the second discharge port. A valve 121 is installed on the outer wall of the second discharge pipe 12. The staff manually opens the valve 121 to discharge the material from the bottom of the barrel body 1.
[0035] The material mixing device of the present embodiment is implemented as follows: multiple connecting rods are welded to the outer wall of a rotating shaft 3, and first and second spiral blades 4 and 5 are welded and fixed to the connecting rods. A worker opens the cover 2 to pour material into the barrel 1. A driver then drives the rotating shaft 3 to rotate, causing the first and second spiral blades 4 and 5 to simultaneously stir the material. Once stirring is complete, the baffle 6 is opened to discharge the material from the first discharge pipe 11. This double-layer spiral blade design improves the stirring efficiency of the material within the barrel 1.
