Description

[0001]
[Industrial application fields]
The present invention provides a synthetic resin mixing and stirring apparatus characterized in that pellets serving as resin raw materials to be supplied to various synthetic resin molding machines are mixed and stirred on average by two motors inside the mixing container after being poured into the mixing container. It is about.
[0002]
[Prior art]
In general, this type of mixing and stirring device is a device that mixes and stirs a resin material, a colorant, and the like by rotating a stirrer provided on left and right vertical stirring shafts with a stirrer connected to a rotating shaft of a motor that can be moved up and down. It is currently used.
[0003]
[Problems to be solved by the invention]
In the case of using one motor in the mixing and stirring apparatus used in the above-described conventional technology, the motor itself is remarkably enlarged, and only the outer periphery excluding the center of the inner surface of the mixing container is mixed. There was a problem that the central portion of the mixing vessel could not be stirred and mixed on average.
The present invention solves such a conventional problem, and its main object is to rotate two motors, a first main motor and a second sub motor, that move up and down around a concentric shaft. The installation area was reduced, and the outer peripheral part of the mixing container was mixed with the stirring blade provided on the outer peripheral rotating shaft, and the central part of the mixing container was sufficiently stirred and mixed with the central stirring blade of the inner peripheral rotating shaft. An attempt is made to provide a mixing and stirring device.
[0004]
[Means for Solving the Problems]
In order to achieve the above object, the mixing and agitating apparatus of the present invention has a plurality of vertical frames and horizontal frames framed in a square shape, and an elevating horizontal frame is installed between the left and right horizontal frames. Two motors, a first main motor and a second sub motor, are placed above the elevating horizontal frame. The first main motor is connected to an outer peripheral rotation shaft that is inserted through the bearing portion at the top of the elevating horizontal frame. In addition, a stirrer for mixing the outer periphery of the mixing container is connected to the outer peripheral rotation shaft. The inner peripheral rotation shaft of the second auxiliary motor is inserted through the inner core of the outer peripheral rotation shaft, and the inner peripheral rotation shaft is provided with a central stirring blade for stirring only the lower center.
[0005]
【Example】
Next, an embodiment of the present invention will be described with reference to the drawings. In FIGS. 1 and 3, the mixer main body (1) has four vertical corner frames (19) (19)... 20) It is framed in a square shape. Between the vertical frames (19) and (19), an elevating horizontal frame (2) that elevates up and down is installed on a standing guide rod. Two motors, a first main motor (3) and a second sub motor (10), are placed on the elevating horizontal frame (2).
[0006]
The first main motor (3) is connected to and connected to an outer peripheral rotating shaft (5) inserted through a bearing portion (4) provided in the lower elevating horizontal frame (2). The outer peripheral rotating shaft (5) is made of various movable small and large cylindrical shapes located at the lower portion, and is connected with a stirrer (14) for mixing and stirring the inner periphery of the mixing vessel (15). The stirrer (14) is vertically provided with vertical stirring shafts (7) and (7) connected to long and short rotating braces (6) and (6) on the left and right. The vertical stirring shafts (7) and (7) are detachably mounted with stirring blades (8) and (8) each provided with several claw pieces hanging downward.
[0007]
The second sub motor (10) is provided with an inner peripheral rotation shaft (11) vertically inserted into the bearing portion (4) and the outer peripheral rotation shaft (5). The inner peripheral rotating shaft (11) is provided with a central stirring blade (12) for mixing and stirring only the inner center of the mixing vessel (15) at the lower end. Reference numeral (16) indicates a separation protrusion protruding from the bottom (17) of the mixing container (15), and (21) and (22) indicate respective reduction gears and the like. It is.
[0008]
[Action]
Since the present invention is configured as described above, the use of the mixing and stirring apparatus will now be described. Various pellet-like resin raw materials and coloring agents are supplied into the mixing vessel (15) from various raw material tanks. To do. At this time, the first main motor (3) and the second sub motor (10) are both stopped at the raised position. Thereafter, the agitator (14) connected to the first main motor (3) is agitated by the rotation of the first main motor (3) and the second sub motor (10) by the lowering operation of the elevating horizontal frame (2). The blades (8) and (8) mix and stir the outer peripheral portion inside the mixing vessel (15), and the central stirring blade (12) of the inner peripheral rotating shaft (11) connected to the second auxiliary motor (10). The central portion inside the mixing vessel (15) is mixed and stirred to mix the whole on average. After the stirring and mixing, the mixing container (15) can be moved by raising the elevating horizontal frame (2) as each motor is stopped. The above operation is repeated to stir and mix various raw materials.
[0009]
【The invention's effect】
Since the present invention is configured as described above, it is possible to use two small and light motors as compared with the conventional one using one large and heavy motor. The operation is very easy and very economical, and the entire interior of the mixing vessel can be uniformly stirred and mixed by the rotation of two motors. The first main motor, the stirring blade provided on the vertical stirring axis of rotation arm rod of the left and right length connected to the outer peripheral rotating shaft, there is surely mixing and stirring can effectively the circumference of the mixing vessel. In addition, the second sub-motor is provided with an inner peripheral rotation shaft inserted into the inner central portion of the outer peripheral rotation shaft, and a central stirring blade is installed at the lower end of the inner peripheral rotation shaft, so that the inner portion of the outer peripheral rotation shaft is The inserted inner peripheral rotation shaft can remarkably reduce the size of the rotating part, and the central stirring blade of the inner peripheral rotation shaft reliably mixes and agitates the central portion of the mixing vessel, and the inside of the mixing vessel is mixed to the average. It has the effect of enhancing the stirring effect.
