Abstract

PURPOSE:To prevent wear of a vessel of a mixing machine by mounting a vessel contg. several kinds of material together with a solvent on two revolving rolls and supporting a flange on a shaft interposing a ball bearing so that the flange may revolve independently of the revolution of the revolving rolls. CONSTITUTION:The flange 3 is revolved freely by the action of the ball bearing 4 independently of the revolution of the revolving rolls 1. Accordingly, when an end of a vessel 8 mounted on the revolving rolls 1 and revolves contacts with the flange 3, the flange is revolved smoothly by the friction of the contact in accordance with the revolution of the vessel 8. Therefore, no slip is generated between the flange 3 and the shaft 2 unlike conventional mixing machines. Namely, the flange 2 revolves without being influenced by the revolution of the shaft 2 by providing the ball bearing 4 between the flange 3 and the shaft 2, thus the damage of the machine and the vessel are prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to mixers for materials mixed with solvents.

BACKGROUND OF THE INVENTION In recent years, with the development of materials, material mixing technology has become increasingly important. Along with this, blending machines have also continued to develop.

A conventional mixer will be described below with reference to the drawings. 2 to 4 show conventional mixers. In FIGS. 2 to 4, reference numeral 1 denotes a rotating roll fixed to a shaft 2, and has a rubber film 1' on its surface. Reference numeral 3 designates flanges for preventing containers from falling off, which are arranged to correspond to both ends of the rotary a-ru 1, and the containers 8 come into contact with the inner surfaces thereof. 9 is rotating roll 1fc
This is a pulley that transmits the driving force for rotation to the rotating roll 1, and is fixed to the shaft 2. Reference numeral 5 denotes a fixed frame on which all ball bearings 6 supporting the shaft 2 of the rotating roll 1 are mounted, and is attached to a stand 7.

The operation of the mixer configured as above will be described below. A container 8 containing a material 10 is placed so that it is supported by the rubber membranes 1' of two rotary rows 21 whose both ends are supported by ball bearings 6. When one rotating roller 21 is rotated in the direction of the arrow by the drive source, the container 8 placed on it also rotates in the direction of the arrow, and the other rotating roller 1
rotates in the same way. By rotating the container 8 in this manner, the materials are mixed. At this time, the collar 3 is fixed to the shaft 2 to prevent the container 8 from falling off in the axial direction of the rotating roller 1. The rotating row 21 is composed of a shaft 2 and a rubber 1, and a container 8 rotates on two rotating rollers 1, and one end of the container 8 continues to rotate while being in contact with the collar 3.

Problems to be Solved by the Invention However, in the above configuration, since the collar 3 and the shaft 2 of the rotating roller 1 are fixed, there is a difference in the rotational speed of the collar 3 and the container 8, which continue to rotate.

In this case, the larger the difference between the diameter of the rotating roller 1 and the diameter of the container 8, the greater the difference in the rotation speed, which will continue to rotate while rubbing against each other, causing wear on one or both of them. .

SUMMARY OF THE INVENTION In view of the above-mentioned problems, it is an object of the present invention to provide a mixer that can prevent wear of the collar and container and prevent damage to the equipment or the container.

Means for Solving the Problems In order to solve the above problems, the mixer of the present invention has a collar that prevents containers from falling off, which is supported by a ball bearing on the shaft so that it can rotate freely regardless of the movement of the rotating rolls. It is assumed that the length is 't%.

Effect of the present invention With the above-described configuration, the collar can freely rotate regardless of the rotation of the rotating roller, and the contacting container rotates at the same rotation speed as the rotating roller, thereby preventing slippage due to the difference in rotation speed between the containers. This can prevent mutual damage.

EXAMPLE Hereinafter, a mixer according to an example of the present invention will be explained with reference to the drawings.

FIG. 1 shows a partial sectional view of a mixer in an embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a rotary a-ra, which is composed of a shaft 2 and a rubber pattern 1' fixed to the outer surface. 6 is a ball bearing, located at both ends of shaft 2 (only one shown)
support. A fixed frame 6 supports the ball bearing 6 and is attached to a stand 7. By inserting a ball bearing 4 between the collar 3 and the shaft 2, the collar 3 is supported so as to freely rotate regardless of the rotation of the rotating roll 1.

The operation of the mixer configured as above will be explained below.

The Eritsuba 3 rotates freely due to the action of the ball bearing 4, and is not affected by the movement of the rotating roller 1. Therefore, when one end of the container 8 rotating on the rotating roll 1 comes into contact with the collar 3, the friction force causes the collar 3 to rotate smoothly in accordance with the movement of the container 8. Therefore, unlike the conventional case, slippage does not occur between the container 8 and the collar 3.

As described above, according to this embodiment, by installing the ball bearing 4 between the collar 3 and the shaft 2, the collar 3 is attached to the shaft 2.
The device can operate regardless of the rotation of the device, preventing damage to equipment and containers.

Effects of the Invention As described above, in the present invention, a ball bearing is inserted between the shaft and the collar that support the rotating roll on which the container is placed, and the slip between the container and the collar is eliminated, thereby preventing mutual damage due to friction. It can be prevented.
