Description

Thin film edge cutting machine

Technical Field

The utility model belongs to film equipment field, concretely relates to film edging machine.

Background

When producing a film, the film is usually trimmed as needed, i.e., both sides of the film are cut off to adjust the width of the film. Currently, pneumatic knives are commonly used for cutting, such as those produced by notoknife. When the pneumatic cutter is used for cutting, a tensioning roller (or called an edge cutting roller) corresponding to the pneumatic cutter is generally provided with a corresponding notch for cutting. If the width of the film needs to be adjusted, the corresponding tensioning roller needs to be replaced so as to adjust the position of the notch, and then the position of the pneumatic cutter is adjusted. The price of single tensioning roller is higher, and heavier, and it is higher to correspond the required cost of purchase tensioning roller according to the width of film, and need spend more time and manual work and change. How to adjust the position of notch fast, the position adjustment that realizes pneumatic cutter is the technical problem that needs to solve at present urgently.

Detailed Description

The following describes in further detail embodiments of the present invention.

As shown in fig. 1 to 3, a film edging machine of the present invention includes a frame 10. The frame 10 is provided with a plurality of tension rollers 12 parallel to each other for tensioning the film. The frame 10 is provided with a slitting roller 14 parallel to the tensioning roller 12, the film likewise passing around the slitting roller 14. The trimming roller 14 comprises a roller shaft 16, a long rubber roller 18 is arranged on the roller shaft 16, a positioning ring 20 is respectively and coaxially arranged on each of two sides of the long rubber roller 18 in a detachable mode, a short rubber roller 22 is respectively and coaxially arranged on the outer side of each positioning ring 20, an annular jacking block (not shown) protruding out of the end face of each short rubber roller 22 is arranged on one side, close to each positioning ring 20, of each short rubber roller 22, and a notch 24 is formed through contact between each annular jacking block and the corresponding short rubber roller 22. The frame 10 is provided with a pneumatic cutter 26 at a position corresponding to the notch 24, and the pneumatic cutter 26 is provided with a circular blade 28 which can extend into the notch 24. The blade 28 is forced by air pressure into the notch 24 to cut, i.e., trim, the film. Because the positioning ring 20 and the short rubber roller 22 are sleeved on the roller shaft 16, the position of the notch 24 can be adjusted by replacing the positioning ring 20 and the short rubber roller 22, and the purpose of adjusting the width of the film is achieved. It is not necessary to replace the entire edge slitting roller 14, thereby reducing costs and improving efficiency.

Further, in order to more conveniently replace the edging roll 14, the following structure is adopted: one end of the roller shaft 16 is fixed to the frame 10 via a bearing (not shown), and a support device 31 is provided on the frame 10 at the other end. The support means comprise a cylindrical body 32 axially mounted on the frame 10 along the axis of the roller 16, a cylindrical needle 34 being movably mounted in the cylindrical body 32. The thimble 34 is provided with a blind hole 36 at an end facing the roller shaft 16, a bearing 30 is provided in the blind hole 36, and the roller shaft 16 is provided in the bearing 30, thereby fixing the whole edge cutting roller 14. The outer wall of the thimble 34 is provided with an external thread, a screw 37 is rotatably provided in the cylinder 32, the screw 37 is engaged with the external thread of the thimble 34, a handle 38 is connected to the screw 37, the screw 37 is rotated by rotating the handle 38, so that the thimble 34 is driven to move back and forth by the thread, thereby fixing or loosening the edging roll 14.

Further, a threaded hole (not shown) is formed in the outer wall of the cylinder 32, and a fastening screw 40 is screwed into the threaded hole, so that the thimble 34 can be pressed by the fastening screw 40, thereby fixing the position of the thimble 34.

Further, a guide rail 42 is provided on the frame 10, and the pneumatic cutter 26 is fixed on the guide rail 42 by a speed wrench (not shown), so that the pneumatic cutter 26 can be replaced or the position of the pneumatic cutter 26 can be adjusted at any time.
