Formula of nano-antibacterial pipe and single-screw extruder for processing nano-antibacterial pipe

Abstract

The invention relates to the technical field of nano-antibacterial pipe extruders, in particular to a formula of a nano-antibacterial pipe and a single-screw extruder for processing the nano-antibacterial pipe. The nano-antibacterial pipe comprises an extruder body, the extruder body is provided with a supporting mechanism, the extruder body is provided with a feeding mechanism for feeding raw materials, the feeding mechanism is provided with an anti-blocking mechanism for preventing blocking during raw material discharging; the supporting mechanism is provided with a dismounting mechanism for assisting in dismounting and replacing of the die head, and the dismounting mechanism is provided with a limiting mechanism for limiting the die head. When the die head on the extruder body is replaced, the bolts in the annular array are detached, one end of the dismounting mechanism is pushed to make the dismounting mechanism abut against the die head needing to be detached, one end of the dismounting mechanism is inserted between the die head and the extruder body, and the dismounting mechanism is pulled away from the direction of the extruder body; and the limiting mechanism limits the die head, so that the die head can be quickly disassembled, and scalding caused by too high temperature is avoided.

Description

Technical field [0001] The present invention relates to the technical field of nano-antibacterial tubing extruders, and is specifically a single screw extruder of nanofacterial tubes and a single screw extruder. Background technique [0002] The PE antibacterial tube is to add a plastic antibacterial agent during the production process. It is generally added to the contactless silver antibacterial agent. The inorganic antibacterial agent is mostly a metal ionic antibacterial agent, consisting of an inorganic carrier and an antibacterial component; by physical adsorption or ion Switching, etc., metal (or ion) such as silver, copper, zinc is fixed to the surface of a porous material such as zeolite, silica gel, and then add it to the article to obtain a material having antimicrobial properties. Single screw extruders are required for nano antibacterial tubes. [0003] However, the current nano-antibacterial tube single-screw extruder is connected to the extruder through the annular...

AI Technical Summary

Problems solved by technology

[0003] However, the die head part of the current nano-antibacterial pipe single-screw extruder is connected to the extruder through an annular array of bolts. When the die head needs to be replaced, the screw is first disassembled, and then the die head is disassembled. The heating components of the extruder are easy to absorb heat due to the close distance, and the temperature of the die head is high, so it is not easy to take and replace. If the die head is replaced after the extruder equipment cools down, it is necessary to restart the extruder heating device, which takes a long time. It affects the processing of pipes; and when the raw materials are unloaded, the hopper is not equipped with an anti-blocking mechanism, and the bottom diameter of the unloading hopper is small, which affects the need to manually swing the gate for anti-blocking, which is not conducive to unloading
