Abstract

PURPOSE:To make the discharge of a remaining material sure by supporting a stirring blade in the upper half part of a case, providing a movable supporting means which is separated from the upper half part to the lower half part of the case and also vibrating the lower half part thereof. CONSTITUTION:When the stirring blade 2 supported in the upper half part 1a of the case is rotated and also either of rocking motors in the left and the right is driven, the powder stuck on a case wall is allowed to fall by the vibration. The powder in either side of the left and the right of the lower half part of the case is transferred to a discharge port by means of both the unidirectional vibrating acceleration due to the vibration motor and the sending of a blade. Thereafter when the driving of the unidirectional vibration motor is stopped and the other vibration motors of the left and the right are driven, the powder in the other sides of the left and the right of the lower half part can be transferred toward the discharge port. The remaining adhered powder can be surely discharged from the discharge port by repeating this operation as necessary.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an improvement in an apparatus for mixing powders such as resins.

Prior Art and Problems Horizontal mixing devices are sometimes used when performing the original mixing of resin compositions or mixing to prevent material separation during storage of mixed raw materials.

However, in this horizontal mixing device, the stirring blade (
Since there is a clearance between the ribbon blade (ribbon blade) and the bottom wall of the case, it is inevitable that the mixed material remains on the bottom wall of the case, and after use, the remaining material must be forcibly discharged.

However, conventionally, a brush is used for cleaning, but the stirring blades get in the way, making it difficult to clean thoroughly.

OBJECTS OF THE INVENTION An object of the present invention is to add self-cleaning means to the mixing device itself to ensure the discharge of the residual material.

Structure of the Invention The mixing device according to the present invention is provided with a movable support means that supports the stirring blade in the upper half of the case and allows the lower half of the case to be supported separately from the upper half of the case. This structure is characterized by providing a vibration means for vibrating the lower half of the case separated from the case.

Description of examples The present invention will be explained below with reference to the drawings.

FIG. 1A is a side view showing a mixing device according to the present invention, and FIG. 1B is a front view showing the same device.

In FIG. 1A and FIG. 1B, 1 is a horizontal case, which is composed of an upper case half 1a and a lower case half 1b. I support 2. The upper half la of the case is supported and fixed on a frame, but the frame is not shown. Reference numeral 3 denotes a discharge port provided at the center of the lower half 1b of the case. Reference numerals 4 and 4 designate a footrest, and numerals 5 and 5 indicate hydraulic jacks, which support the lower case half 1b, and the lower case half 1b is normally closely integrated with the upper case half 1a. 6
, 6 are springs inserted between the lower half of the case 1b and the leg base 4. Reference numerals 71 and 712 indicate vibration motors, which are provided on both left and right sides of the lower half of the case 1b across the discharge port.

FIG. 2 shows the procedure for discharging the material remaining at the inner bottom of the case, in which the lower half 1b of the case is separated from the upper half 1a of the case by a lowering operation of the hydraulic jack 5.5 across a gap g9g, The lower half of the case 1b is supported by a spring and can vibrate.

By rotating the stirring blade 2 supported on the upper half of the case 1a and operating either of the left and right photographing motors, the powder adhering to the case wall is caused to fall by vibration, and the vibration motor The powder on either the left or right side of the lower half of the case can be moved toward the discharge port by unidirectional vibration acceleration and blade feeding. Next, by stopping the operation of the vibration motor in one direction and operating the other vibration motor on the left and right sides, the powder on the other side of the left and right sides of the lower half of the case can be moved toward the discharge port. Thereafter, by repeating the above operation as necessary, the remaining adhering powder can be reliably discharged from the discharge port.

As shown in FIG. 3, the left and right vibration motors 71.7
2 can be installed so that their vibration directions are perpendicular to the center of the lower half of the case. Further, each motor 71.72 can also be attached via a leaf spring 81.82, and the attachment direction of the leaf spring 81.82 is parallel to the direction of the respective excitation force.

With this configuration, when one vibration motor 71 is operated, the other vibration motor 72 can be separated from the vibration system by the elasticity of the leaf spring 82 (the excitation force of the vibration motor 71 is applied to the leaf spring 82). , acts in a direction that bends and deforms this leaf spring 82). That is, when the vibration motor 71 is in operation, the other stopped vibration motor 72 can be held almost stationary. At this time, since the leaf spring 81 is installed parallel to the direction of the vibration force, the vibration force of the operating vibration motor 71 is not equally affected by the leaf spring and can be applied to the case. It can act on the lower half.

Therefore, the movement of the material remaining at the bottom of the case due to vibration becomes very smooth and efficient, and it also protects the bearings of the stopped vibration motor from being damaged, which is very effective in stabilizing the life of the device. It is.

Effects of the Invention The mixing device according to the present invention has the configuration as described above,
The residual adhering powder on the inner surface of the case can be removed by the cooperation of the vibration motor and the stirring blade, and the cooperative effect allows for reliable self-cleaning.
