Automatic membrane change device of automatic filling binding machine

Abstract

The invention discloses an automatic membrane change device of an automatic filling binding machine and belongs to the field of food machinery. The automatic membrane change device of the automatic filling binding machine realizes to change membrane automatically. The automatic membrane change device of the automatic filling binding machine comprises a membrane roll change device I which is provided with a membrane roll (10) in use and a spare membrane roll (11) and further comprises a membrane deviation correcting device II, a membrane number reduction detecting device III and a pneumatic membrane switching device IV, when the membrane reduction detecting device detects that the membrane on the membrane roll (10) is reduced by a certain degree, the automatic membrane change device enables the speed to be reduced automatically to prepare for changing membrane; when a photoelectric membrane sensor (41) perceives the end of the membrane roll (10) in use, the front end of the spare membrane roll (11) is bonded with the end of the membrane roll (10) in use through a cylinder (46), the 180 degrees position change is finished through a roll change shaft (1), and accordingly the membrane change is finished. The automatic membrane change device of the automatic filling binding machine is capable of substituting manual membrane change and making full use of membranes so that the waste is avoided, and moreover, the membrane change is finished without stopping the automatic filling binding machine, so that the production is not influenced; the automatic membrane change device of the automatic filling binding machine is easy to manufacture, assemble, disassemble, regulate and maintain and is convenient to operate.

Description

technical field [0001] The invention belongs to the field of food machinery and relates to an automatic membrane changing device in an automatic filling and binding machine. Background technique [0002] In the prior art, the packaging film used in the automatic filling and ligating machine is used continuously after the film roll is installed. When the film on the film roll is almost used up, the machine must be shut down with a part of the film reserved and replaced manually. The reason why a part of the film is reserved for the new film roll is that when the film is almost used up, the transport of the film is not normal, which will cause the packaging to be unqualified and waste the main source material, and the replacement film roll must be shut down, unload the original film roll and install a new one. Turning on the machine after the film roll is not only a waste of film, affecting production efficiency, but also inconvenient to operate. Contents of the invention ...
