Description

Detailed Description of the Invention (Industrial Field of Application) The present invention relates to a rotary cylindrical processing device, and more specifically, the present invention relates to a rotary cylindrical processing device, and more specifically, it is used to process articles to be cooled or heated, such as synthetic resins, crushed fish or meat, in the form of sheets, etc. It relates to a device for processing by supplying the liquid in an appropriate form and pressing it onto the surface of a rotating cylindrical body that is being cooled or heated.

(Prior Art) Conventionally, this type of device has been used as a cooling device that is part of a crushing device in the manufacturing process of thermoplastic, thermosetting synthetic resins, etc. −
It is disclosed in Japanese Patent No. 225882. The conventional rotating cylindrical processing apparatus described in the publication includes a rotatably supported cylindrical body 1 and a cooling or heating mechanism for cooling or heating the cylindrical body 1, as shown in FIG. 2 and
A supply unit 3 that supplies a workpiece to the surface of the cylindrical body 1; and a blender disposed adjacent to the supply unit 3 that presses and rolls the workpiece 4 discharged from the supply unit against the surface of the cylindrical body 1. The yarn roll 5 is stretched along the outer periphery of the cylindrical body 1, and the cylindrical body l
an endless belt 6 that transfers the workpiece 4 supplied to the surface of the cylinder 1 while keeping it in close contact with the cylinder 1; It consisted of a crusher 7 for crushing 4 objects to be processed.

As is clear from FIG. 2, the endless belt 6 is wound around three support rollers 8a, 8b, and 8c, and the heald portion between the support rollers 8a and 8b is a cylindrical body.
It is partially wrapped around the outer circumference. In the range of wrapping the endless belt 6 around the cylindrical body 1, if the support roller 8b side is the inlet part and the support roller 8a side is the outlet part, the support roller 8a and support roller 8b are the wrapping ranges of the processed material Q1. The moving direction of the endless belt is changed to almost the opposite direction on the entrance/exit side, and the heald 6 is supported. The workpiece 4 that is separated from the surface of the cylindrical body 1 at the exit of the winding range of the endless belt 6 is one endless belt.
The heald 6 is transported to the top of the support roller 8a while riding on the heald 6, and as the heald 6 changes its moving direction to almost the opposite direction and falls downward, it is crushed into small pieces by the crusher 7. However, at that time, some of the objects 4 to be processed may adhere to the endless belt 6 and not be separated from the heddle. For this reason, a side scraper 9 of the support cola 8a is installed to scrape off such a workpiece 4 from the end' (/schelt 6). On the other hand, the gap is smaller than the thickness of the processed object 4 and is positioned so as to maintain a gap that does not come into contact with the heald surface.

(Problem B to be Solved by the Invention) However, in the conventional rotary cylindrical processing device described above, it is difficult to scrape off the processed material 4 that remains attached to the crusher 7 from the nut 6 at the end. Since the scraper 9 was installed on the side of the support roller 8a, a large amount of fine powder generated when crushing the workpiece 4 entered the gap between the surface of the endless belt and the tip of the scraper 9 at once. Otherwise, the powder may accumulate on the scraper 9 and gradually grow, and the fine powder lumps may enter the above-mentioned gaps. When the fine powder lump enters the gap between the tip of the scraper 9 and the surface of the endless belt in this way, the position of the gap, that is, the portion of the en 1-less held 60 that the tip of the scraper 9 faces, is the area around which the support roller 8a wraps. Because it is in the contact area, there is no room for the entrefluoro to escape, and as a result, the fine powder lumps -1,
There was a problem in that the surface of the endless belt 6 was strongly rubbed and damaged.

The purpose of the present invention is to solve the serious problems of the conventional art, and therefore, a scraper is used to scrape off the processed material that remains attached to the endless belt at the outlet of the cylindrical wrapping range of the endless belt. An object of the present invention is to provide a rotating cylindrical processing device that does not damage an endless belt even when the belt is present.

(Means for Solving the Problems) The rotating cylindrical processing apparatus of the present invention supplies a workpiece to the surface of a cylindrical body that is rotatably supported and heated or cooled, and rolls it with a play shear roll. In a rotating cylindrical processing device that presses and transfers a rolled workpiece to the surface of the cylindrical body using an endless belt partially wrapped around the surface of the cylindrical body, the workpiece is transferred to the surface of the cylindrical body of the endless belt. At the exit side of the wrapping range, the direction of the endless belt is changed to almost the opposite direction, and the front end of the endless belt is attached to the endless belt on the moving direction side near the contact point position on the belt withdrawal side of the support roller that supports the endless belt. The present invention is characterized in that a scraper is disposed to scrape off and remove the processed material.

(Function) According to the rotating cylindrical processing device of the present invention, the objects to be processed, which are transferred by being pressed against the surface of the rotating cylindrical body by the endless belt, are separated from the cylindrical body surface and sent to the crusher when they exit the wrapping range of the endless belt. Fall. At this time, the workpiece that remains attached to the endless belt is removed by a scraper provided on the endless belt moving direction side near the contact point position on the belt exit side of the support roller of the endless belt located at the exit of the winding range of the endless belt. scraped off by If a fine powder lump generated when the crusher crushes the workpiece is caught in the minute gap between the scraper tip and the surface of the endless belt, the part of the endless belt facing the scraper tip will be in contact with the support roller. Since the endless belt is detached from the belt, the endless belt bends to the rear side and escapes, and the fine particles pass through the minute gap without being strongly rubbed against the endless belt.

(Example) Hereinafter, the rotary cylindrical processing apparatus of the present invention will be described in more detail with reference to the embodiment shown in the attached concave surface.

FIG. 1 shows the main parts of a rotating cylindrical processing device 210 according to an embodiment of the present invention. The first example shows this example.
In the figures, the same or corresponding parts as the conventional rotary cylindrical processing apparatus shown in the second part are given the same reference numerals, and the explanation thereof will be omitted.

Generally, when a heald is guided by being wrapped around a support roller, the side where the heald starts to wrap around the support roller is called the entry side, and the side where the belt exits from the support roller is called the exit side. The contact start point and the contact end point between the support roller and the belt on the belt entry side and the heald exit side are both referred to as contact points. In the rotary cylindrical processing apparatus 10 of this embodiment, the contact point 2 on the heald withdrawal side of the support roller 8a is disposed on the exit side of the winding range of the cylindrical body L of the endless belt 6 shown in FIG.
The scraper 11 is placed so that the tip thereof faces the belt portion between the place and the point Q on the moving direction side of the endless belt 6.
is provided. However, this heald exit side contact point P
does not include the position of Further, point Q is the limit point at which the processed material scraped off the endless belt 6 by the scraper 11 enters the crusher 7, and is a position where one edge of the crusher 70 is adjacent to the heald portion on the withdrawal side. Therefore, in reality, the location where the tip of the scraper 11 is located does not include this point Q, but is closer to the support roller 8a than this point.

Further, the scraper 11 is installed at an angle greater than the angle of repose so that crushed powder of the object to be processed does not accumulate.

Rotating cylindrical processing apparatus 1 of this embodiment configured as described above
According to No. 0, the basic operation is similar to the conventional rotary cylindrical processing device, when the object to be processed is pressed against the surface of the cylindrical body 1 by the endless belt 6 and transferred, and when it exits the wrapping range of the endless belt 6, it touches the surface of the cylindrical body 1. and falls into the crusher 7. At this time, the workpiece that remains attached to the endless belt 6 is removed from the contact point 2 on the belt withdrawal side and the point Q on the support roller 3 a' of the endless belt 6, which is located at the exit of the winding range of the endless belt 6. It is scraped off by a scraper 11 provided between. If a fine powder lump generated when the crusher 7 crushes the object to be processed is caught in the minute gap between the tip of the scraper 11 and the surface of the endless belt 6, the part of the endless belt facing the tip of the scraper is moved by the support roller. Since it is out of the contact area with 8a, the endless belt 6 bends to the back side and escapes, and the fine powder lump passes through the minute gap without being strongly rubbed against the endless belt 6.
As a result, damage to the surface of the endless belt is prevented.

(Effects of the Invention) As explained above, according to the rotating cylindrical processing device of the present invention, the endless belt movement direction side near the contact point position on the heald withdrawal side of the support roller disposed at the exit portion of the winding range of the endless belt By providing a scraper at the end of the endless belt, even if the crushed powder of the workpiece gets caught in the minute gap between the scraper tip and the surface of the endless belt, the surface of the endless belt will not be damaged, and the life of the endless belt can be extended. Stable operation of the device can be guaranteed.
