Description

Technical Field

[0001] The utility model relates to the technical field of trolley case production, in particular to a trolley case shell forming device. Background Art

[0002] As people's living standards improve, more and more people choose to travel. Trolley cases are the first choice of suitcases for people to travel, which provides great convenience for people's travel. Trolley cases are very convenient to use during travel because they have pull rods and rollers. They are loved and widely used by people. The shell of a trolley case is generally processed by blow molding. However, after the shell is formed, the excess edge material around it needs to be cut.

[0003] After searching, the application number is: CN201922104906.9, which is a blow molding device for the production of luggage. After blow molding, the cylinder can drive the circular cutter to directly cut the remaining edge material after the blow-molded plate is formed. No manual cutting is required, the cutting is convenient, and the integrated fast cutting is performed at the same time, and it is not easy to leave too many burrs on the edge. The lower end of the circular cutter is provided with a circular cutting edge, and mounting plates are provided on both sides of the circular cutter. A disc is fixed on the end face of the propulsion rod of the second cylinder, and the disc is mounted on the upper surface of the mounting plate by bolts. The blow molding plate can be quickly blown up, and the outer surface of the template slides and fits on the inner wall surface of the square ring shell. When the template and the module rise, they can fit and slide, and can be supported by sliding positioning. The blow pipes are distributed on the front and back sides of the support platform, and the blowing is even. The crimping ring frame is fixed by multiple bolts. The bolts are evenly distributed and firmly fixed. The crimping ring frame is tightly crimped, which will not cause air leakage during blow molding.

[0004] The blow molding device for suitcase production disclosed in this patent can effectively cut the excess edge material on the molded trolley suitcase shell, but it requires tools to operate the circular cutter when disassembling and assembling it, which is relatively cumbersome. Moreover, after long-term use, the threads on the bolts, mounting plates and discs are prone to loosening due to wear, and the circular cutter may shake or fall off. Utility Model Content
