Description

Technical Field

[0001] The invention relates to the technical field of plastic pipe processing, and in particular to a station-type bent pipe blanking and assembling device. Background Art

[0002] Traditional plastic bent tube straws are basically packaged directly as finished products during processing, and there are few products with additional accessories on the bent tube. This is mainly because the wall thickness of the plastic bent tube is very thin, usually only 0.2mm, and the tube body is relatively soft, making automatic assembly difficult. Generally, this type of tube blank is not used for automatic assembly.

[0003] Although the actual application of the plastic bent tube straw assembly field is relatively small, with the development of the market, there is a demand for the production of customized medicinal tubes based on thin-walled bent tube straws. This customized medicinal tube is used for the storage and rapid administration of powder (pills). The main feature is that the powder (pills) are filled in the plastic bent tube, and the two ends of the plastic bent tube are respectively equipped with a cap and a suction port. The processing process is mainly to first process a plastic bent tube with accessories at one end by the rubber and plastic processing line, and then hand it over to the pharmaceutical company to fill it with powder (pills) and then package it. Among them, the bent tube blanking assembly is the most important part of the entire customized medicinal tube processing and assembly process.

The positioning pin at the end can effectively position the plastic elbow when pressing down to ensure assembly accuracy. The thread clamp is used during lifting to effectively increase the friction on the wall of the plastic elbow, maximize the avoidance of scratches on the wall, and reduce the impact on the product appearance.
