JPS62204906A - Method and device for manufacturing curled chip from waste plastic film - Google Patents

Abstract

PURPOSE:To permit the cost of titled chips to be saved remarkably by manufacturing the chips through only three processes of crushing, mixing and cooling selection. CONSTITUTION:Waste plastic film is crushed and cut into flakes. When the chips are mixed forcibly by a mixer or the like, the temperature of material is raised by shearing effect or mutual friction between materials whereby the curling of the material is started. The progressing degree of the curling is controlled by cooling forcibly the jacket of the mixer or the like through water cooling. The curled chips are sent into a cooling screening machine to cool and select (screen) the fine pieces and the fine powder of the chips simultaneously while combing them up by slowly rotating vanes in a cylindrical drum provided with small holes. The chips are stocked once in a receiving tank, thereafter, are sent into a weighing and bag filling machine to weigh and bag fill them, then, final products may be obtained. Respective processes are connected by pneumatic tubes using blowers whereby continuous work may be effected.

Description

[Detailed Description of the Invention] 〇 [Prior Art] Waste plastic film treatment methods include not only waste treatment such as landfilling and incineration, but also treatment methods by thermal decomposition, recycling treatment, and reforming. There is quality treatment.

From the perspective of resource reuse, pigeon coops, landfills, and incineration are out of the question, but in pyrolysis, recycling, and reforming treatments, crushed flakes that have been processed into granules or powder can be molded. Most of the material was processed into various molded products.

[Problems to be solved by the invention] The conventional method described above had problems such as the following: 0 A processing step is required to transform the crushed flakes into granules or evaporators, and Since a molding process is required to make a molded product, processing costs are high, and from the perspective of recycled product utilization, it is necessary to perform a modification process to maintain the quality of high-cost products. The reforming process was also a major contributing factor to the high cost.

The purpose of the present invention is to provide a reprocessing method and apparatus for solving the above-mentioned problems. [Means for solving the problems] To achieve this purpose Therefore, this invention has the following error.
It is set as tFtG.

(A manufacturing method for obtaining curled chips from waste plastic film, which consists of combining each of the 11 steps.

■ The first step is to crush waste plastic film into flakes.

@ The second step is to shape the flakes into curled chips by vigorous stirring and heating.

θ The shaped curled chips are cooled and sorted (sieved)
The third step.

(2) A production device for obtaining sword-shaped chips from waste plastic film, which consists of the combination of the following devices:

By strongly stirring the 0 @ 7 lakes with a mixer, etc., the shearing effect caused by mixing and the layer lines between the materials are eliminated by water cooling. By controlling by forced cooling, maintaining a predetermined temperature between 40 and 100℃, and controlling the mixing time, curled chips with a predetermined shape can be stably produced. The chips are sent to the cooling W#, where they are not scraped up by gently rotating blades in a cylindrical drum with narrow holes, so they are simultaneously cooled and sorted (divided into m) into fine pieces and powder. Cooling is carried out in the form of a progression,! lil another finished curled tip,
Once stocked in the receiving tank, it is sent to the weighing and bagging machine, where it is weighed and packed into bags to become the finished product. They are connected by a transport pipeline, and the materials to be processed can be transported, making continuous work possible.

〔Example〕

The embodiments of this invention will be described in more detail below. 0 Φ Waste plastic film is put into the crusher 1 and crushed into flakes so that the cut pieces do not exceed 4 cm in size◎ ＠ A certain amount (Ill ~ 20 instants) of the crushed flakes is put into the disc-shaped mixer 2 using the industrial quantity hopper, and when the cutter blade of the mixer is strongly stirred at 1.05 rpm for a certain period of time (3 to 8 minutes), The temperature of the material rises and the sword -
Since the temperature of the material is 50 to 80, the temperature of the material should be adjusted to 50 to 80.
By maintaining the temperature at 0°C, the degree of curling can be controlled and the curled chips are shaped into curled chips with a predetermined shape.The curled chips discharged from the disc mixer 2 are passed through the cooling sieve machine 3. A SM metal fitting 12 and a rubber seal 13 are attached to a blade 11 that rotates slowly in a cylindrical drum 10 made of punched metal with 2x holes.
As a result, the curled chips fall in the cylindrical drum 10 and are cooled by repeated scraping, and at the same time, the chips and powder are removed through holes in the punching metal. The removed pieces are stored in a hopper 6 installed at the bottom of the cylindrical drum IO,
On the other hand, the powdered material is sucked through the exhaust pipe 14 by an exhaust blower, and is poured into a water tank for #F% purification.

■ The curled chips that have been cooled to room temperature and sorted (sieved) are once stocked in the receiving tank 7, and sent to the weighing bag @ 4, where they are weighed and packed into bags to obtain finished products. The equipment in the section above is connected by a pneumatic pipeline 5 containing a blower, and a cyclone 8 is connected to each of these pipelines.
is provided to supplement the fine powder contained in the material fed from the previous process.

〔Effect of the invention〕

The effects of implementing this invention are listed below.

B) Recycling of waste plastic film conventionally required a complicated process of granulation and then injection or extrusion molding, but the method of this invention involves breaking, mixing, cooling and sorting. It is possible to commercialize the product with only 3 steps, resulting in a large cost reduction - KIIJ
This is a processing method that can reduce the amount of water used, so it has a great advantage.

In the strong agitation mixing method of the present invention, the amount of heat required to produce curled chips can be met by just the heat generated during mixing, so it is a method that does not require a heat source for one process, and is therefore inexpensive. There are benefits to it.

(c) The method of the present invention can greatly reduce the processing time required to produce a product, which can greatly contribute to reducing manufacturing costs.

(-4) When the curled chips obtained by the method of the present invention are used as a "filling material for pillows", the feel and heaviness during use are comparable to those of buckwheat hull JIC. Therefore, it can be said that it is a new material @1 arrow that can be widely used as a filling material for things other than pillows.

(e) Processing of waste plastic film Opening the lid is a major cost problem, including the problem of environmental pollution due to the waste plastic film, but by processing it using the method of this invention, it can be effectively This invention can be said to have great merits in terms of social and environmental conservation, as it can be used as a rental source.
