By being provided with cone connection so that fixed block can be even closer with the cooperation of the port of the paper web of film roll, to thin
The fixation of film roll is more stablized, and by being provided with limiting slot, can so that the end of countershaft is limited, and reduces shaft rotation
Shaking in the process, while being supported by being provided with idler wheel countershaft, reduce rubbing between the end of shaft and mounting plate
Power is wiped the both ends of shaft are respectively put into limiting slot and are abutted with idler wheel so that shaft rotation process is smooth laborsaving, you can
Realize being rotatably connected for shaft and supporting rack, simple in structure, replacement easy to disassemble.
Description of the drawings
Specific embodiment of the present utility model is described in further detail below in conjunction with attached drawing, wherein：
Fig. 1 is a kind of front view of unreeling structure for film Scissoring device of the utility model；
Fig. 2 is a kind of vertical view of unreeling structure for film Scissoring device of the utility model.
Specific implementation mode
As depicted in figs. 1 and 2, a kind of unreeling structure for film Scissoring device, including supporting rack 1 and shaft 2, support
There are two the settings of frame 1, and the both ends of shaft 2 are rotatablely connected with two supporting racks 1 respectively, are set with paper web 4 in shaft 2, are rolled up on paper web 4
It is wound with plastic film, the both ends of paper web 4 are respectively arranged with fixed block 5, the company being slidably matched with shaft 2 is provided on fixed block 5
Hole 6 is connect, the side of fixed block 5 is provided with the mounting hole 7 penetrated through with connecting hole 6, and mounting hole 7 is threaded with fixing screws 8, Gu
Determine block 5 and be provided with the cone connection 9 coordinated with the port of paper web 4 towards the side of 4 end of paper web, is provided on supporting rack 1
Mounting plate 10 is provided with the limiting slot 11 coordinated with the end of shaft 2 on mounting plate 10, is located at limiting slot 11 on mounting plate 10
Side is provided with the idler wheel 12 abutted with shaft 2.By the way that film roll to be sleeved in shaft 2, then pass through the fixation in shaft 2
Block 5 and the both ends of film roll are fixed, so that film roll can release plastic film with 2 synchronous rotating shaft 2 of shaft, lead to
It crosses and fixed block 5 and shaft 2 is slidably connected, be fixed by screw after the distance between two fixed blocks 5 can be adjusted, from
And realize the fixation to the film roll of different length, and by being provided with cone connection 9 so that fixed block 5 can with it is thin
The port cooperation of the paper web 4 of film roll is even closer, to which the fixation to film roll is more stablized, by being provided with limiting slot 11,
It can so that the end of countershaft 2 is limited, reduce the shaking in 2 rotation process of shaft, while by being provided with idler wheel 12
Countershaft 2 is supported, and the frictional force between the end and mounting plate 10 of shaft 2 is reduced, so that 2 rotation process of shaft is suitable
Cunning is laborsaving, and the both ends of shaft 2 are respectively put into limiting slot 11 and are abutted with idler wheel 12, you can realization shaft 2 can with supporting rack 1
Rotation connection, simple in structure, replacement easy to disassemble.
Preferably, it can be fixedly connected by connecting rod 13 between two support frames as described above 1, the bottom surface and ground of connecting rod 13
Being fitted and connected the both ends of bar 13 can be fixedly connected by welding with two supporting racks 1 respectively, by being provided with connecting rod 13,
