Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a stock guide device in a rubber kneading roll device, and more specifically, a part of a rubber material to be kneaded is prevented from dropping off to the outside of a guide member or the outside of a reversing conveyor, and kneading is always performed with a uniform blending. The present invention relates to a stock guide device in a rubber kneading roll device capable of obtaining a rubber material.
[0002]
[Prior art]
Conventionally, rubber kneading roll devices, calendar devices, and the like are known as devices for kneading rubber materials and the like repeatedly and finally forming a sheet-like material.
[0003]
As such a roll device, for example, as shown in FIG. 5, kneading is performed on both end sides between a pair of rotatable front rolls 2 and a back roll 3 disposed horizontally on the conveyor 1. As shown in FIGS. 6 (a) and 6 (b), a pair of plate-like guide members 4a and 4b are arranged opposite to each other so that the rubber material W does not protrude from both sides of the front roll 2 and the back roll 3. (For example, refer to Patent Document 1).
[0004]

Japanese Patent No. 2757508 (first to third pages, FIG. 4)
[0005]
[Problems to be solved by the invention]
However, the roll device as described above may be the plate-shaped guide members 4a and 4b as described above when the front roll 2, the back roll 3 and the rubber material W are wound around. When the rubber material W that has come out of the roll 3 is returned to the upper side of the front roll 2 and the back roll 3 through the transport conveyor 1 and the reverse conveyor 5 as shown in FIGS. , 4b is wider than the inner width of the rubber material W.
[0006]
For this reason, the rubber piece Wa in the outer portion of the sheet-like rubber material W falls to the outside of the guide members 4a and 4b, and the working environment is deteriorated, and a lot of wasted rubber is generated, and a more uniform compounding is performed. There were problems such as damage.
[0007]
This invention pays attention to such a conventional problem, and when the rubber material is repeatedly kneaded, it effectively prevents the rubber material debris from falling outside the guide member, and the front roll and back roll input side It is an object of the present invention to provide a stock guide device in a rubber kneading roll device which can always obtain a rubber material with a uniform blending by returning to the above.
[0008]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the pair of guide members are disposed so as to be able to approach and separate at the center upper portion in the width direction of the front roll and the back roll, and are kneaded on the inner center lower side of the guide member. a guide protrusion to guide the center of always front roll and the back roll rubber material is provided, the guide projection is tapered Te widthwise smell between the front roll and the back roll toward the center bottom surface of the guide member inner surface The guide protrusion is formed in a taper shape so as to be 100 mm or more from the guide member toward the center side of the front roll and the back roll at the center in the width direction of the front roll and the back roll. The gist is that the thickness is 500 mm or less .
[0010]
In this way, the pair of guide members are disposed so as to be able to approach and separate at the center upper portion in the width direction of the front roll and the back roll, and the rubber material to be kneaded is always placed on the inner center lower side of the guide member at the front roll. and a guide protrusion to guide provided at the center side of the back roller, the guide projection, the front roll and the back roll and tapered so as to be tapered toward the center bottom surface of the guide member inner surface Te width direction odor The guide protrusion is formed at a central portion in the width direction between the front roll and the back roll from 100 mm to 500 mm from the guide member toward the center of the front roll and the back roll. This effectively prevents the rubber material debris from falling to the outside of the guide member. By returned to the insertion portion side with Lumpur, but always it is possible to obtain a rubber material having a uniform blend.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
[0012]
In the following description, the same components as those in the conventional example are denoted by the same reference numerals, and the description thereof is omitted.
[0013]
1A and 1B are a side view of a pair of guide members 14a (14b) of the present invention installed on one side between the front roll 2 and the back roll 3, and guide members 14a ( 14b), and the guide member 14a (14b) always guides the rubber material W to be kneaded to the center of the inner surface of the guide members 14a and 14b to the roll center side as shown in FIGS. Guide protrusions 6a and 6b are provided.
[0014]
The pair of guide members 14a and 14b are disposed in a central upper part of the front roll 2 and the back roll 3 so as to be able to approach and separate via a moving device (not shown), and the guide protrusions 6a and 6b are a pair of guide members 14a. , 14b is formed so as to be tapered toward the center of the bottom surface.
[0015]
The guide protrusions 6a and 6b are preferably set to a predetermined length L toward the roll center, for example, 100 mm or more and 500 mm or less. If it is 100 mm or less, there is a risk that fragments of the rubber material W will fall outside the guide members 14a and 14b, and if it is 500 mm or more, the rubber at the center between the front roll 2 and the back roll 3 is used. The interval between the portions where the material W bites becomes narrow, and the rubber material W cannot be efficiently kneaded.
[0016]
Thus, the taper-shaped guide protrusion 6a, 6b which always guides the rubber material W to be kneaded to the roll center side is provided at the center of the bottom surface of the pair of guide members 14a, 14b, as shown in FIG. As described above, the rubber material W is always guided to the center side of the front roll 2 and the back roll 3, and therefore, fragments such as rubber pieces Wa of the rubber material W do not fall outside the guide members 14 a and 14 b, It is possible to obtain a rubber material that is always uniformly blended.
[0017]
【The invention's effect】
In the present invention, as described above, the pair of guide members are disposed so as to be able to approach and separate at the center upper portion in the width direction of the front roll and the back roll, and are kneaded on the inner center lower side of the guide member. always guide projections for guiding the center side of the front roll and the back roll is provided, the guide protrusion, tapers toward Te widthwise smell between the front roll and the back roll in the center bottom of the guide member inner surface The guide protrusion is formed in a taper shape so that the guide protrusion has a width of 100 mm or more and 500 mm from the guide member toward the center of the front roll and the back roll at the center in the width direction of the front roll and the back roll. By forming the following , the following excellent effects are obtained. (A). When the rubber material is repeatedly kneaded, it is possible to effectively prevent pieces of rubber material and the like from falling outside the guide member, and the working environment is not deteriorated, and a lot of wasted rubber is not generated.
(B). It is possible to effectively prevent the rubber material fragments and the like from falling outside the guide member, and to obtain a rubber material having a uniform composition at all times.
(C). The guide protrusion is preferably set to 100 mm or more and 500 mm or less from the guide member toward the center of the front roll and the back roll at the center in the width direction of the front roll and the back roll . If it is 100 mm or less, there is a risk that fragments of the rubber material W will fall to the outside of the guide member as in the conventional case, and if it is 500 mm or more, the rubber material W will bite into the center of the front roll and back roll. The interval becomes narrow and the rubber material W cannot be efficiently kneaded.
