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, there is a clearance between the stirring blade (ribbon blade) and the bottom wall of the case, so it is inevitable that the mixed material remains on the bottom wall of the case, and after use, the remaining material is forced to target discharge is necessary. However, conventionally, a brush is used for cleaning, but the stirring blades get in the way, making it difficult to clean thoroughly.

OBJECT OF THE INVENTION An object of the present invention is to add a 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, with an upper case half 1a and a lower case half 1a.
The stirring blade 2 is supported by bearings 21 and 22 at both ends of the case upper half 1a. The upper half of the case 1a 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 reference numerals 5 and 5 indicate hydraulic jacks, which support the lower half 1b of the case, and the lower half 1b of the case is normally closely integrated with the upper half 1a of the case. 6, 6 is the lower half of the case 1b and the leg stand 4
This is a spring inserted between the 71, 72
is a vibration motor, which is provided on both left and right sides narrowing the above-mentioned discharge port in the lower half part 1b of the case.

Fig. 2 shows the procedure for discharging the material remaining at the inner bottom of the case, and by lowering the hydraulic jacks 5, 5, the lower half 1b of the case is removed from the upper half 1a of the case.
The lower half 1b of the case 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 vibration motors, the powder adhering to the case wall is dropped by vibration, and the vibration motor causes the powder to fall. The powder on either the left or right side of the lower half of the case can be moved toward the discharge port by the directional vibration acceleration and the feeding of the blades. 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. From then on,
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 and 72 can be installed so that their vibration directions are perpendicular to the center of the lower half of the case. In addition, each motor 71, 72 is connected to a leaf spring 8.
The plate springs 81 and 82 can also be attached via the plate springs 81 and 82, and the attachment direction of the leaf springs 81 and 82 is parallel to the direction of the respective excitation forces.

Under such a configuration, one vibration motor 7
1, 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 the 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 that time, the excitation force of the operating vibration motor 71 is not influenced in any way by the plate spring 81 because the plate spring 81 is installed parallel to the direction of the excitation force. can act on the lower half of the case.

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, and can remove residual adhering powder on the inner surface of the case by the cooperation of the vibration motor and the stirring blade.
Due to their synergistic effect, reliable self-cleaning can be performed.
