Embodiment Construction

[0016] 1. The pipe body is made of aluminum-plastic composite sheet. First, the aluminum-plastic composite sheet is sterilized with ultraviolet light, and then heated by a high-speed pipe making machine at high frequency and welded to grow the pipe;

[0017] 2. The long tube is pulled by the synchronous motor on the traction belt. At the same time, the photoelectric sensor is used to send a signal according to the color mark on the sheet. Under the command of PV, the rotary knife is driven by the servo motor to rotate and cut into Short tubes.

[0018] 3. On the hydraulic paste injection machine, the worker inserts a short pipe, the pipe is 1.00mm to 1.5mm higher than the mandrel step, mixes it with 40% low density and 60% high density polyethylene, and heats it in the cylinder of the hydraulic paste injection machine To the upper part of 230 ° C, the lower end of about 250 ° C, inject 4kg ~ 6kg with an appropriate pressure, keep the pressure at 1.5kg ~ 2.5kg, push it on the m...

Abstract

The invention discloses an easily-opened aluminum plastic composite packing hose and a manufacturing method thereof, and adopts an aluminum plastic composite sheet to manufacture the hose body, comprising the following steps of: firstly conducting ultraviolet light disinfection to the aluminum plastic composite sheet; later forming a long hose by the high-frequency heating and welding of a high-speed hose-manufacturing machine; and then cutting the long hose manufactured into a plurality of short hoses in a rotating way. The short hoses are on a hydraulic paste-injecting machine, and a mouth piece with a thread on a shoulder and a polygonal orifice cover at the orifice is molded by one shot with a mold; the molded hoses are placed into a rotating box; and a cap in which a thread and a polygonal pit are arranged is molded with polyethylene plastic by one shot. The easily-opened aluminum plastic composite packing hose and the manufacturing method thereof have the advantages of advanced process, simple method, convenient use, and quick and sanitary orifice cover opening, lower the cost, improve the production efficiency, and avoid the pollution of articles in the hose due to the opening of the orifice.

Description

technical field [0001] The invention relates to a method for manufacturing an aluminum-plastic composite packaging paste tube for toothpaste, paste medicine, food, etc., and belongs to the technical field of daily necessities. Background technique [0002] Toothpaste and pasty medicine, food, etc. are often packaged in tubes. The materials of the packaging cream tubes of existing tourism toothpaste and paste drugs, food, etc. include plastic tubes, aluminum thin top tubes and aluminum-plastic composite tubes. Its main composition is composed of a tube body with both ends closed and a cap with an unsealing device. During manufacture, the tube body is injected or stretched, and then the shoulder is processed by injection molding. The nozzle is set on the top of the shoulder. An opening thimble recessed in the cap is designed on the top of the cap. When in use, unscrew the cap, use the thimble to cut through the sealing film of the nozzle, and extrude toothpaste or paste medi...
