Abstract

The utility model relates to a plastic thin film cutting machine which comprises knife shafts arranged in parallel, a knife carrier and a blade, wherein the knife carrier has a concentric revolving body structure and is encircled on the knife shafts, the blade is annular and fixedly arranged on the knife carrier, and the knife carrier is movably connected with the knife shafts. The plastic thin film cutting machine provided by the utility model is detachable, with controllable cutting widths and long life time.

Description

The plastic sheeting cutting machine

Technical field

The utility model relates to a kind of cutting machine, relates in particular to a kind of cutting machine that plastic sheeting is cut of being used for.

Background technology

Plastic sheeting need carry out in various degree cutting according to actual conditions after producing, the different in width of formation, the plate-like or the thread product of different-diameter after the processing after cutting are widely used in various fields.Because plastic sheeting itself has softness, characteristics such as pulling force is strong and yielding, present in addition cutting machine almost is original frame for movement, directly be welded on blade on the cutter shaft, or adopt common butterfly blade, and the cutter axial dimension is big, and cutting edge is thin, the width size can not be controlled, and the cutter poor radiation, service life is short, and the cutter that is used to cut is after working for a long time, meeting is turned or edge of a knife interlock is not tight, make existing cutting machine or cutting tool when plastic sheeting is cut, often can not reach needs of production, perhaps line is run in cutting, perhaps cutter has burr, causes the waste or the loss of plastic sheeting.

Summary of the invention

In order to solve the above-mentioned technical problem that exists in the background technology, the utility model provides a kind of dismountable, cutter to cut that width can be controlled and the plastic sheeting cutting machine of blade long service life.

Technical solution of the present utility model is: the utility model provides a kind of plastic sheeting cutting machine, it comprises two cutter shafts that are parallel to each other and install, cutter shaft is the rigid rotating axle, be connected with knife rest on the cutter shaft, knife rest is concentric rotary structure, is fixedly connected with annular blade around being arranged on the cutter shaft upper tool post.

As preferably, described knife rest is fixed on the cutter shaft by the counterbore screw.

As preferably, described blade is fixed together by push type broach screw or welding or clamping and knife rest.

As preferably, on described two cutter shafts on fixing separately a plurality of knife rests the corresponding coherent of blade connect.

The utility model has the advantages that: the utility model adopts the cutter structure of adjustable movable knife rest, and cutter for same tool changing, toolsetting operation easier are reduced greatly, makes significantly shorten non-cutting time simultaneously; In addition, the utility model make cutter for same can the scope of cutting can precisely control and detachably, strong, the long service life of thermal diffusivity.

Description of drawings

Fig. 1 is the partial structurtes schematic diagram of the utility model cutting mechanism;

Fig. 2 is that the A of Fig. 1 is to view.

The specific embodiment

Referring to Fig. 1, the utility model provides a kind of plastic sheeting cutting machine, comprises two cutter shafts 1 that are parallel to each other and install, cutter shaft 1 is the rigid rotating axle, is connected with knife rest 2 on the cutter shaft 1, and knife rest 2 is concentric rotary structure, around being arranged on the cutter shaft 1, be fixedly connected with blade 3 on the knife rest 2.

As shown in Figure 2, the knife rest 2 on the cutter shaft 1 has a plurality of, and knife rest 2 is fixed on the cutter shaft 1 by counterbore screw 4, so knife rest 2 can be from directly dismounting on the cutter shaft 1, it is quite convenient to use.Several knife rests 2 on two cutter shafts 1 are distributed as corresponding one by one the arrangement on the axial plane of cutter shaft 1, and the blade 3 cutting edge coherents on each knife rest 2 are connect.The quantity of blade 3 is identical with the quantity of knife rest 2, and it is shaped as annular, and section is a rectangle, and the corner angle of both sides are the shearing edge of a knife on its cylindrical, by push type broach screw 5 with itself and the knife rest 2 fastening one that are connected into.When the view picture plastic strap from shearing edge of the present utility model through out-of-date, drive the blade 3 on each knife rest 2, just realized the continuous longitudinal shear of the utility model to view picture plastic sheeting band.

Claims

1. a plastic sheeting cutting machine comprises two cutter shafts that are parallel to each other and install, and it is characterized in that: described cutter shaft is the rigid rotating axle, be connected with knife rest on the described cutter shaft, described knife rest is concentric rotary structure, around being arranged on the cutter shaft, is fixedly connected with annular blade on the described knife rest.

2. plastic sheeting cutting machine according to claim 1 is characterized in that: described knife rest is fixed on the cutter shaft by the counterbore screw.

3. plastic sheeting cutting machine according to claim 2 is characterized in that: described blade is fixed together by push type broach screw or welding or clamping and knife rest.
