Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for kneading materials and an apparatus therefor, and more specifically, the present invention relates to a method for kneading materials to be kneaded and an apparatus therefor. The present invention relates to a kneading method and a kneading device for kneading materials which are designed to shorten the time to improve productivity and reduce costs.

[Prior art]

Conventionally, in order to keep the physical properties of a kneaded material such as a rubber material in a constant state, the kneaded material wrapped around the kneading roll surface is peeled off and then returned to the kneading roll in a balled state. A tandem kneader is known, in which a plurality of kneading rolls are arranged in series and the kneading work is repeated while sequentially feeding the kneading material.

By the way, in the former case of item 1, the worker cuts off the kneaded material that has adhered to the surface of the kneading roll with a scalpel, etc., and then rolls the peeled off kneaded material and rolls it back onto the kneading roll. Since the kneaded material was fed into the kneaded material, the workability was extremely poor and it was dangerous, and cutting the kneaded material required a lot of effort and time, as well as requiring great skill.

Furthermore, in the case of the latter tandem system, there are the following problems.

(When the Al kneading material is insufficiently kneaded, the dispersion of sulfur is poor. Therefore, it is necessary to add more kneading rolls, but in this case, the increase in the number of rolls increases the cost and makes maintenance difficult. , it also requires a lot of effort and time.

(Adding a kneading roll to an existing line requires the kneading machine to be stopped for a number of days, and it is not possible to add a kneading roll due to the problem of installation space, and there are restrictions on the number of compounds available.

(C) When conveying from the kneading roll to the sheet output roll, a distance is required due to the condition of the angle of the conveyor.

(d) It is necessary to raise the height of the kneading roll installation.

(e) The entire train becomes longer, and productivity decreases due to the extension of processing time such as temporary stoppage measures.

[Purpose of the invention]

This invention was devised by paying attention to the problems of the prior art, and its purpose is to prevent the distance between the seven bundle rolls and the sheet delivery roll from becoming unnecessarily long, and to reduce the overall train length. It is possible to shorten the kneading time, change the kneading effect without increasing the number of rolls, and to repeatedly knead the kneaded material without requiring much effort and time. It is an object of the present invention to provide a method for kneading a kneaded material and an apparatus therefor, which can improve physical properties and work efficiently.

[Structure of the invention]

In order to achieve the above object, the present invention receives the kneaded material extruded from the kneading machine by a discharge conveyor disposed at the bottom of the mixing roll, and the kneaded material conveyed by this discharge conveyor is delivered to the side of the kneading roll. The kneaded material placed on the transfer means is then moved up and down to above the input section of the kneading roll via a lifting device, and the kneaded material placed on the transfer means is After the kneaded material is introduced into the input section of the kneading machine via the input means and extruded again, it is raised onto the kneading roll via the transfer means and the lifting device.
The gist of this method is to supply the kneaded material to the sheet output roll via a charging means.

In addition, in the present invention, a discharge conveyor is installed at the discharge lower part of the kneading roll for receiving the kneaded material and conveying it to the side of the kneading roll. A transfer means that can be raised and lowered via an elevating device is disposed on the side of the transfer means, and when the transfer means is raised to the kneading roll input section, the above-mentioned kneading material is transferred to the kneading roll. The gist of the invention is to provide a feeding means for feeding the sheet into a sheet feeding roll installed on the opposite side of the lifting device.
