Description

TECHNICAL FIELD The present invention relates to a cylindrical stirrer for stirring and mixing materials such as powders of different kinds or different colors.

[Prior Art] Conventionally, as a stirrer and A for stirring and mixing materials such as powders of different kinds or different colors, for example, FIGS.
There are many types as shown in the figure. In this product, a shovel 2 is arranged in a stirrer body 1 formed in a substantially cylindrical shape, and the shovel 2 is rotated by a motor 11 provided on a pedestal 10 on which the stirrer body 1 is installed. The materials are agitated and mixed in the main body 1. When the inside of the agitator A is cleaned and switched when agitating and mixing the other mixture, the agitator body 1 of the conventional example shown in FIGS. 3 and 4 is used. A plurality of openable / closable lids 4 provided on the front side of the peripheral surface are opened, the inside is cleaned through the opening 3, and switching is performed. The conventional example shown in FIGS. 5 and 6 is used. Then, the lid 4 provided along the longitudinal direction on the upper surface side or the front surface side of the peripheral surface of the stirrer main body 1 is opened to clean the inside to perform switching.

[Problems to be Solved by the Invention] However, in the conventional example as described above, in the case where the plurality of lids 4 are provided, each lid 4 is opened to open the opening 3 when cleaning is performed at the time of switching. The inside of the stirrer A is to be cleaned through the inside of the stirrer A, but when cleaning the entire inside, it is necessary to carry out the cleaning with the body placed in each opening 3, There is a problem that it is difficult to clean because it is necessary to change the body to 3
As in the conventional example shown in FIGS. 5 and 6, in which the lid 4 on the upper surface side or the front surface side is opened to clean the inside,
Cleaning is performed with the waist bent from above, and the posture of the worker who performs the cleaning is poor, and there is a risk of falling inside if the work efficiency is large and the size is large. It is expensive, especially when cleaning the inside through the opening 3, especially between the mounting member 6 to which the shovel 2 is mounted with respect to the shaft 5 shown in FIG. 7 and the inner surface of the side plate 1a. However, there was a problem that it was hard to reach and it was not possible to completely clean the remaining space.

The present invention seeks to solve the above problems,
The purpose is to improve the efficiency of cleaning at the time of switching, and to ensure complete cleaning without remaining amount,
Another object is to provide a cylindrical stirrer that can be easily switched.

[Means for Solving the Problems] In order to achieve the above object, a cylindrical stirrer A according to the present invention has a stirrer body 1 whose outer shape is formed into a substantially cylindrical shape.
In a stirrer in which a material mixing shovel 2 is rotatably disposed inside, a part of a peripheral surface of the stirrer main body 1 including end portions of both side plates 1a located on both side parts of the stirrer main body 1 Is cut out in the longitudinal direction to form an opening 3, and a lid 4 formed in a substantially curved shape so as to be flush with the inner surface of the agitator body 1 is provided in the opening 3 so as to be openable and closable. is there.

[Operation] When the inside of the cylindrical stirrer A is cleaned for switching after stirring and mixing of the materials, the door body 4 is opened and the end portions of both side plates 1a located on both side portions of the stirrer body 1 are included. The inside of the stirrer body 1 is cleaned through an opening 3 formed by cutting a part of the peripheral surface of the stirrer body 1 in the longitudinal direction.

[Embodiment] FIG. 1 is a perspective view of a cylindrical stirrer A according to an embodiment of the present invention. The cylindrical stirrer A can stir and mix materials such as resin powders of different types and different colors,
The outer shape is formed into a substantially cylindrical shape, and a rotatable excavator 2 is provided inside. A plurality of the shovels 2 are provided at regular intervals in the longitudinal direction of a shaft 5 provided between both side plates 1a located on both sides of the agitator body 1, and the shaft 5 is rotated by a motor (not shown). Thus, the agitator body 1 is rotated along the inner surface thereof. That is, the shovel 2 is installed in a state of being separated from the shaft 5 via the mounting member 6, and when rotated, rotates along the inner surface of the stirrer body 1. Reference numeral 7 is an exhaust pipe provided on the upper surface side of the agitator body 1, and 8 is a supply port for supplying the material into the agitator body 1. A part of the peripheral surface of the agitator body 1 including the ends of both side plates 1a of the agitator body 1 is cut out in the longitudinal direction to form an opening 3. A lid 4 formed in a substantially curved shape so as to be flush with the inner surface of the stirrer body 1 is arranged so as to be openable and closable. That is, the peripheral surface of the stirrer body 1 is cut at a right angle in the longitudinal direction with respect to the circumferential direction of the stirrer body 1 to form the opening 3, and the opening 3 is provided with the lid 4 which can be opened and closed. There is. This lid 4 is formed in a substantially curved shape,
As shown in FIG. 2, when the shovel 2 that rotates along the inner surface of the stirrer body 1 when it is closed is rotated, the inner surface of the stirrer body 1 has substantially the same shape as the inner surface of the stirrer body 1 so that it can rotate smoothly. A curved surface portion 4a having a curved surface is formed. The flange portion 4b on the outer periphery of the curved surface portion 4a is machined, and the flange portion 4b is grooved and provided with a sealing material 9 such as an O-ring or sponge packing. At the time of opening and closing, it is opened and closed by turning around a fulcrum shaft a via a lid opening / closing drive motor. When the lid 4 is closed, a constant pressure is applied by a torque limiter provided in the drive motor. It can be closed in the state.

However, when cleaning is performed at the time of switching, the lid 4 is opened and cleaning is performed through the opening 3. The opening 3 includes the end portions of the side plates 1a located on both sides of the agitator body 1. Since a part of the peripheral surface of the stirrer main body 1 is cut out in the longitudinal direction, the lid 4 is opened so that both side plates 1a are partially removed, and the shovel 2 and the mounting member 6 are provided.
Will protrude from the stirrer body 1 to facilitate cleaning, especially the shovel 2 located at the end.
Also, the space between the mounting member 6 and the inner surface of the side plate 1a can be easily cleaned.

In the embodiments described above, the case of the stirrer is shown, but the present invention may be adopted in the mixing and kneading machine.

[Effects of the Invention] As described above, the present invention forms an opening by notching a part of the peripheral surface of the stirrer body in the longitudinal direction including the ends of both side plates located on both sides of the stirrer body to form an opening. However, since a lid that is formed in a substantially curved shape so as to be flush with the inner surface of the stirrer main body is provided in this opening so as to be openable and closable, the entire inside of the stirrer main body is opened through the opening when switching. It can be cleaned and can be cleaned without entering the agitator body, and it can be cleaned in a comfortable posture with the hand extended, reducing the labor load during cleaning. In addition, the work efficiency is improved, and the side plate is partially removed by opening the lid, so it is possible to securely clean every corner of the side plate, which was difficult to clean in the past, and it is safe and The switching work can be performed quickly.
