Device for automatic replacement and external reminding during film covering packaging

Abstract

The invention relates to the technical field of automatic packaging, and discloses a device for automatic replacement and external reminding during film covering packaging. The device comprises a shell, a packaging film shaft is movably connected to the lower end of the inner wall of the shell, a contact mechanism is movably connected to the left end of the packaging film shaft, and a connecting rod is fixedly connected to the left end of the contact mechanism. The left end of the connecting rod is fixedly connected with a moving rod, the right end of the moving rod is movably connected with a compression spring, the right end of the moving rod is fixedly connected with a trigger mechanism, the right end of the trigger mechanism is movably connected with a contact, the right end of the contact is fixedly connected with a protective shell, and the upper end of the moving rod is movably connected with a transmission rod. The upper end of the transmission rod is movably connected with a pressure block. And the triggering mechanism makes contact with the contact, so that internal current is switched on, an external alarm lamp flickers, external personnel are reminded, and the effect that the external personnel are automatically reminded when the internal packaging film is consumed up is achieved.

Description

technical field [0001] The invention relates to the technical field of automatic packaging, in particular to a device that automatically replaces and reminds the outside during film-coated packaging. Background technique [0002] With the gradual development of society, people's living standards have been significantly improved. Due to the relatively developed business in modern times, people have a great demand for the use of goods, so the workload on packaging is relatively strong. Therefore, the packaging of goods is generally All items are packaged by machine, which is intelligent, efficient and time-saving. [0003] However, at present, there are still defects that need to be overcome when the film is replaced in automatic packaging. When packaging items, the machine is generally used to release the film for lamination. When laminating, often due to the use of the film It needs to be replaced after the film is finished, which is a waste of time. At the same time, becau...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a device that automatically replaces and reminds the outside when the film-coated packaging is used up. When the inner packaging film is exhausted, it automatically reminds outsiders and at the same time automatically reminds the inner packaging. The advantage of replacing the film solves the problem that when the film is covered, it is often necessary to replace the film after use, which is a waste of time. At the same time, the film is usually in the packaging process, which often occurs suddenly and easily affects the packaging effect. question
