Double-emptying double-storing non-stop material connecting device

Abstract

The invention discloses a double-emptying double-storing non-stop material connecting device, and particularly relates to the field of the packaging and bagmaking industry. An upper film unwinding device is in transmission connection with an unwinding pneumatic shaft through a gear; an encoder is arranged on the rear side of the upper film unwinding device; a first swing arm, a continuous tractiondevice, a storage device, a traction device and a second swing arm are sequentially connected through a film coil; a lower film unwinding device is arranged under the upper film unwinding device andcomprises a lower encoder, a lower swing arm, a lower continuous traction device, a lower storage device and a lower traction device; and the lower encoder, the lower swing arm, the lower continuous traction device, the lower storage device and the lower traction device are sequentially connected through a film coil. According to the device, storage structures are arranged in the upper unwinding device and the lower unwinding device, and the machine has no need to be shut down when a film is replaced, so that the risk of scaling the film on the machine can be avoided, the waste is reduced, andthe production cost is reduced.

Description

technical field [0001] The invention relates to a non-stop material receiving device with double discharge and double storage, in particular to the field of packaging and bag making industry. Background technique [0002] At present, the large food packaging bags on the market are made of two rolls of film, but if waste can be reduced and material feeding can be achieved without stopping the machine, a storage device must be used. At present, the double discharge can only be used as a storage device by unwinding the roll, and the upper one. The roll cannot be used as a material storage structure, so when the film is replaced, the machine must be stopped, and the film on the machine may be scalded when the machine is stopped, which is a relatively large waste and greatly increases the production cost. Contents of the invention [0003] The purpose of the present invention is to provide a double-discharging and double-storage non-stop material receiving device to solve the a...
