Automatic pull-out device for inner plastic part of cosmetics packaging material bottle lid

Abstract

The invention discloses an automatic pull-out device for an inner plastic part of a cosmetics packaging material bottle lid which is provided with an outer lid and the inner plastic part embedded intothe outer lid, wherein the inner plastic part is provided with a threaded hole. The automatic pull-out device is characterized by comprising a bracket and an unloading column, wherein the upper end of the unloading column is provided with a threaded column part which is in threaded connection to the inner plastic part; a through hole for allowing the plastic column to movably arrange in a throughmode is formed in the bracket; an elastic part for enabling the unloading column to keep move-up trend is arranged on the bracket; under the state of keeping the unloading column move up, the threaded column is exposed with the top surface of the bracket; and a drive mechanism for driving the unloading column to move downwards is further arranged on the bracket. During pull-out, the cosmetics packaging material bottle lid is in threaded connection onto the threaded column part, and the unloading column moves downwards relative to the bracket under driving of the drive structure; the bottom surface of the outer lid is blocked by the top surface of the bracket; and the inner plastic part moves down from the through hole along with the unloading column, so that pull-out of the inner plasticpart is realized. According to a test, the device only needs one person to perform pull-out operation which originally needs five persons for a workshop, so that efficiency is greatly improved, and cost is greatly reduced.

Description

Technical field [0001] The invention relates to a disassembly tool, in particular to a device for automatically pulling out plastic parts in a cosmetic packaging material bottle cap. Background technique [0002] The opening of the container is closed by the bottle cap, and the contents contained in the container can be confined in the container and prevent overflow from the opening. The cosmetic bottle containers with openings are generally single-layer caps, and some are double-layer caps. The double-layer bottle cap has an outer cover and an inner plastic part fixed in the outer cover. The advantage of the existing double-layer bottle cap is that the inner plastic part belongs to inherent packaging. The outer cover is adjusted according to the manufacturer, which reduces the number of mold openings. s. [0003] In the actual production process, there will be cases where customers request to change the product, or defective products during the production process will be repaire...

AI Technical Summary

Problems solved by technology

[0003] In the actual production process, there will be situations where customers request to change the product, or defective products will be repaired during the production process. This kind of change only needs to replace the outer cover or inner plastic parts. In order to save costs, manual extraction is required. The method of separating the inner plastic parts from the outer cover is time-consuming and labor-intensive, and the efficiency is low. It requires multiple employees to operate to meet the operation requirements, which greatly increases the production cost of the enterprise.
