Detailed Description

In the high-efficiency plastic film splitting machine shown in the attached drawing, a film stretching frame can be rotatably positioned on a base 2 around a horizontal axis, the axes of a film unwinding frame and the film stretching frame are arranged in parallel, and a motor drives the film stretching frame to rotate through a belt wheel set (the drawing is clear; the motor and the belt wheel set are omitted). In the film stretching frame, a film stretching shaft 8 can be rotationally positioned on a film stretching support 1 around a horizontal axis through a bearing, two support frames (the support frames comprise a flange head 5 which is fixed with the film stretching shaft and the plane of the flange head is vertical to the axis of the film stretching shaft and a plurality of adjusting rods 6 which are radially fixed on the plane of the flange head through bolts) are arranged at two ends of the film stretching shaft in parallel and fixed with the film stretching shaft, and a plurality of film stretching rods 7 are arranged in parallel with the film stretching shaft and two ends of the film stretching rods are respectively fixed with the support frames. The film unwind stand is an unwind shaft 11 rotatably positioned on an unwind stand 12 by bearings that are interfittable with a cavity in the center of the wound plastic film (the center of the wound plastic film is typically a cylindrical core).

The adjusting rod is provided with a plurality of adjusting holes 6-1 distributed along the length direction of the adjusting rod, screw holes which are axially arranged are respectively formed in two ends of the film stretching rod 7, and an adjusting bolt 13 penetrates through one of the adjusting holes and then is screwed and matched with the screw holes, so that the adjusting rod is fixedly connected with the film stretching rod. Obviously, the film stretching rod is fixed at different adjusting hole positions, and the circumference of the film which winds the film stretching frame for one circle can be changed.

Furthermore, a reinforcing connecting rod 3 is arranged between the adjacent adjusting rods; the two ends of the reinforcing connecting rod are respectively fixed with the adjusting rods one by one (recommended bolt fixation). The reinforcing connecting rod, the film stretching rod and the adjusting rod can be fixed by the same bolt (as the adjusting bolt shown in figure 2); when the reinforcing connecting rod and the film stretching rod are respectively fixed in different adjusting holes of the adjusting rod, bolts are respectively adopted.

The utility model discloses a theory of operation is: firstly, adjusting the fixed position of a film stretching rod on an adjusting rod according to the length of a cut film (the circumference of a circle of the film stretching frame of the splitting machine is just equal to the length of 1 plastic film; and according to the length of a cut plastic film 9, the circumference of the circle of the film stretching frame of the splitting machine can be changed by adjusting the fixed position of the film stretching rod on the adjusting rod); the entire roll of plastic film 10 is then threaded onto the unwind stand and rotatably positioned thereon. Then pulling out a section of plastic film from the plastic film and fixing the section of plastic film on 1 of the film stretching rods (only adhesive tape is used for fixing the section of plastic film), and starting a motor to drive a film stretching frame of a splitting machine to rotate; according to the number of the required plastic films to be cut, a plurality of splitting machine stretching frames are required to rotate for several circles (generally, the same length specification amount is mostly hundreds of sheets, the length change of the cut films is overlarge due to the fact that the number of the rotating circles of the splitting machine stretching frames is too large, and generally, the film is required to be rotated for about 50 circles every time). After the plastic film on the film stretching frame of the splitting machine is rolled up, an art designer knife cuts the film along the edge of a certain film stretching rod by 1 knife, and the plastic films with required number can be obtained.
