Plastic extruding machine

Abstract

The invention discloses a plastic extruder including the material canister, the screw stem, the shell, the discharge head, the first barrier, the second barrier, the discharge hole. The character is that the drawknife is installed in the end of the screw stem; the protecting wire net which has the discharge gate is installed between the screw stem and the second barrier. The hollow is formed by the screw stem end and the inwall of the shell which is set the deslagging mouth. The invention can discharge the slag through the deslagging mouth because of the drawknife, so it need not stop the machine to change the filter screen.

Description

【Technical field】 [0001] The invention relates to a machine for making plastic, in particular to an improved invention of a plastic extruder. 【Background technique】 [0002] At present, in order to recycle waste plastics and waste garbage plastic bags and re-produce them into plastics, they are usually processed by plastic extruders. Plastic extruders in the known technology basically all include hopper, heater, barrel and screw rod. Check the Chinese patent, wherein the utility model patent with the notification number CN2194257Y discloses the following content: a plastic extruder, including an organic barrel, the two ends of the barrel are respectively a feed port and a discharge port, arranged along the outer wall of the barrel There are heating and cooling devices, and there are screw rods and filter screens inside the machine barrel. The feature is that at least two filter screens are fixed on a filter screen support that can move relative to t...

Problems solved by technology

Since there are a large amount of sundries such as iron wires, iron nails, gravel sand and wood chips in the above-mentioned raw materials for producing plastics, when these waste plastic raw materials are to be regenerated into plastics, they must be selected or washed to remove sundries, but manual processing is required. It must be incomplete to remove these debris

When using the above-mentioned disclosed technical solutions to regenerate plastics, the machine must be continuously suspended during production, and the filter screen must be replaced continuously. Some waste plastics with a lot of impurities cannot be processed at all, so they have to be discarded. When they are washed by rainwater, they will cause water pollution. Discarding plastic that can also be reused is a waste of resources
