Description
Technical Field
The invention relates to the field of material packaging, in particular to a film feeding device of a film packaging machine.
Background
The existing film packaging machine usually pulls out a film by the extrusion rotation of a group of film pulling belts or a group of film pulling wheels driven by a motor, and introduces the subsequent processes of the packaging machine such as bag making, bag sealing, filling and the like, the structure of a film feeding mechanism is complex, and in actual operation, the film feeding speed and the film pulling speed are easily asynchronous, so that the problems of nonstandard packaging length, easy deviation and the like are caused.
Disclosure of Invention
In order to solve the technical problems, the invention provides a film feeding device of a film packaging machine, which can synchronize film feeding and film pulling, enable a film feeding mechanism to share the weight of most of packaging materials and realize the packaging of heavier materials.
The invention is realized by the following technical scheme:
the film feeding mechanism is fixed on the frame and comprises a film feeding motor and two film feeding rollers, the film feeding motor is connected with the film feeding rollers through gears, the control device is connected with the film feeding motor of the film feeding mechanism and the film pulling motor of the film pulling mechanism, and the control device controls the operation of the film feeding motor and the film pulling motor to enable the film feeding speed and the film pulling speed to be synchronous.
Further, the film material roll is placed above the two film feeding rollers, the two limiting rings are arranged on the film feeding rollers, the positions of the limiting rings can be adjusted, and the limiting rings are arranged on two sides of the film material roll.
Further, draw membrane mechanism including drawing membrane motor, drawing membrane wheel 1, drawing membrane wheel 2 and closing device, draw membrane motor and draw membrane wheel 1 to be connected, closing device with draw membrane wheel 2 to be connected, closing device will draw membrane wheel 1 and draw membrane wheel 2 to extrude together mutually.
Further, the film feeding motor and the film pulling motor are stepping motors or private clothes motors.
The working principle is as follows: the film feeding mechanism rotates the film material roll to feed out the film, the film forms a cylinder shape after passing through the forming mechanism of the packaging machine, then the film pulling mechanism extrudes the side edge of the rolled film, and the rolled film is sealed and cut off by the sealing mechanism of the packaging machine to complete one-time packaging. The film feeding speed and the film pulling speed are synchronous by controlling the cooperative work of the film feeding mechanism and the film pulling mechanism, the film is in a tensioning state between the film feeding mechanism and the film pulling mechanism, and the film feeding mechanism can share the gravity of most of packaging materials.
The invention has the beneficial effects that: 1. the film feeding mechanism and the film drawing mechanism work synchronously to avoid the deviation of the film, the packaging length is standard, 2, the film feeding mechanism shares most of material weight to avoid the film drawing mechanism from generating large pulling force to damage the film, and thus heavier materials can be packaged.
