Specific embodiment
The present embodiment is the utility model preferred embodiment, other its all principles and basic structure are identical with the present embodiment
Or it is approximate, within scope of protection of the utility model.
Attached drawing 1 is refer to, the utility model mainly includes engine base(It is not drawn into figure), die holder 1, upper mold seat 2, cutting die 3,
First blowing wheel 4, the second blowing wheel 5, material collecting device 8, the first material pressing device 10, drawing material 11 and second material pressing device 12 of device,
Die holder 1 and upper mold seat 2 are correspondingly arranged, and upper mold seat 2 is arranged on 1 top of die holder, is fixedly mounted on upper mold seat 2 and is useful for being punched
The cutting die 3 of fabrication hole corresponds on die holder 1 at 3 position of cutting die and is equipped with lower cutting die, the first blowing wheel 4 and second accordingly and puts
Material wheel 5 is separately mounted on engine base, the first blowing wheel 4 be equipped with sill band 6, for sill band 6 carry out blowing, second
Blowing wheel 5 is equipped with PET film material strip 7, for carrying out blowing, in the present embodiment, the first blowing wheel 4 and second to PET film material strip 7
Blowing wheel 5 is set in the same horizontal line, and the first blowing wheel 4 is arranged on 5 outside of the second blowing wheel, i.e., the first blowing wheel 4 is under
The distance between die holder 2 is less than the distance between the second blowing wheel 5 and die holder 2, is then 4 distance of the first blowing wheel in other words
Die holder 2 is relatively near.First blowing wheel 4 and the second blowing wheel 5 are referred to as feeding in 1 one side of die holder, the present embodiment
Side, material collecting device 8 are referred to as rewinding side in 1 opposite side of die holder, the present embodiment.Material collecting device 8 is mounted on engine base
On, the first material pressing device 10 is provided between material collecting device 8 and die holder 1, used PET film material strip 7 passes through the first binder
It is wrapped in after device 10 on material collecting device 8, in the present embodiment, the first material pressing device 10 uses two rollings being bonded to each other together
Wheel, one is driving wheel, and one is driven wheel, and first driving means, first driving means are installed with together with driving wheel
Driving wheel is driven to rotate, by the cooperation between driving wheel and driven wheel used PET film material strip 7 is pulled to travel forward, with
Material collecting device 8 is installed with rewinding driving device together, by rewinding driving device material collecting device 8 is driven to rotate, will used
The PET film material strip 7 crossed is wrapped on material collecting device 8.In the present embodiment, PET film material strip 7 is sandwiched in the master of the first material pressing device 10
Between driving wheel and driven wheel, the charging rate of PET film material strip 7 determines that material collecting device 8 rotates too fast by the first material pressing device 10
When, it is sandwiched in due to PET film material strip 7 between the driving wheel and driven wheel of first material pressing device 10, then it is empty to generate material collecting device 8
The phenomenon that turning will not generate charging.Material device 11 is drawn to be mounted on engine base, material device 11 is drawn to be arranged on the rewinding side of engine base, is led to
